Summary of information:We have more than ten years of production experience in the screw industry. The main products are: elastic cotter pin, l...

The motor bearing retaining ring is used to fix the axial position of the bearing. The structure of the bearing retaining ring 1 in the prior art is shown in FIG. 1 , which is a ring-shaped sheet-like structure with a gap, the inner diameter of which is smaller than the inner diameter of the connected bearing, and the outer side 11 of the ring is a continuous arc shape. The inner side of the ring is provided with a groove 12, 13 of the same size on both sides of the midpoint of the ring, and the width of the groove is equal to the distance from the groove to the gap of the ring. When the axial locking force (impact) of the bearing retaining ring of this structure is greater than 6.5N, serious deformation will occur or even the retaining ring will be separated from the shaft shoulder. In order to solve this problem, when the axial locking force is greater than 6.5N, the prior art generally adopts a two-ring combined structure of steel wire ring + bearing retaining ring, and its installation state is shown in Figure 2, as shown in Figure 2, l It is a bearing retaining ring in the prior art, 3 is a locking nut, 4 is a fan blade insert, 5 is a bearing, 6 is a shaft, and 7 is a wire ring. However, such a structure is costly and troublesome to assemble, especially if the bearing retaining ring is not placed in place during assembly, the bearing retaining ring is at risk of being crushed.

The conventional auger bit structure 1 includes a rod body 11, a screw head 12 provided on one end of the rod body 11, a drill tail 13 provided on the other end of the rod body 11, and a plurality of threads 14 arranged around the rod body 11; Wherein, the periphery of the drill tail 13 defines a parting line 15, and the parting line 15 makes the drill tail 13 symmetrically divided into a side 131 and a side 132, and a cutting end 133 is formed at the junction of the end of the side 131 and the end of the side 132, respectively. The cutting end 133 is concavely provided with a quarter-turn chip flute 134 in the same direction of the helix, and the edge 132 continues the chip flute 134 and has a quarter-turn chip flute 135 with different helical curvatures. , using the chip groove 134 and the chip groove 135 to be connected by different helical curvatures, so that the drill tail 13 can form a symmetrical and complete chip groove of 190 degrees.

The development of a structure with simple production, reasonable structure and stable feeding is of great significance to the field of riveting automation. Technical realization elements: The purpose of this utility model is to overcome the deficiencies in the prior art, and to provide an automatic feeding device for pressure riveting nuts, which has a compact structure and a reasonable design, and can realize the automatic conveying of the pressure riveting nut on the pressure riveting die. Reduce the use of space, improve work efficiency and save labor costs. According to the technical scheme provided by the utility model: the automatic feeding device for riveting nuts, which is characterized in that: it includes an installation bracket, a connecting frame, a flap bracket, a material pushing cylinder, a material pushing block and a flap; the flap bracket is arranged on the installation Below the bracket and attached to the mounting bracket through the connecting bracket.

Most of the capacitors on the market have two pins, which are the connection terminals of the positive and negative electrodes of the capacitor. At present, there is a big hidden danger in these capacitors, that is, the connection between the pins and the core inside the capacitor is basically a stick-on connection. When the capacitor is working, the internal temperature rises rapidly, and the stick-type connection is unstable after being heated, and it is easy to detach Or loose.

Here Yueluo eliminates the drawbacks. The purpose of Yueluo is to provide a locking screw by which the gap existing between the locking screw and a transverse hole in a locking screw can be eliminated. Yueluo achieves the proposed object with a locking screw, which has the features of claim 4 . The line connecting the centers of gravity of the respective axially continuous orthogonal cross-sectional areas of the locking screw is regarded as a line. The advantage achieved by Yueluo can basically be seen that, due to the locking screw of Yueluo, the gap between the horizontal hole of the screw and the locking screw can be eliminated. Other advantages are as follows - the insertion accuracy and surgeon time spent remain within the range to date; - the strength of the locking screw is maintained; and - the extraction of an expired broken screw is assured. The further composition of Yueluo and Yueluo is explained in more detail below by means of schematic diagrams of parts of various embodiments.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: butterfly bolts, GB9074.13 hexagon bolts with washers, mechanical equipment bolts, GB819 flat head cross recessed bolts and other products, we can provide you with products suitable for you fastener solutions.
