Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to a positioning mechanism for bolt processing. Background Art

[0002] A bolt is a mechanical part that is used to fasten two or more parts together with a matching nut by rotating. A bolt usually consists of a head and a screw (a cylinder with external threads). A positioning mechanism for bolt processing is a device specially designed to accurately position and fix bolts during bolt processing. The main purpose of this mechanism is to improve the accuracy and efficiency of bolt processing, ensure that the bolt can be accurately installed in the predetermined position, and meet specific connection requirements.

[0003] Some existing positioning mechanisms use relatively simple positioning methods, such as simple pin hole positioning or clamping devices, whose positioning accuracy may not meet the requirements of high-precision bolt processing, which can easily lead to deviations in the bolts during the processing and affect the quality of the final product. Utility Model Content

[0004] The utility model aims to provide a positioning mechanism for bolt processing, which can improve the positioning stability of the bolts and solve the problem of poor positioning stability of the bolts in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A positioning mechanism for bolt processing comprises a base, a notch is arranged at the upper end of the base, an electromagnet is fixedly connected to the bottom of the notch, a movable plate is slidably connected inside the notch, a permanent magnet is fixedly connected to the lower end of the movable plate, the permanent magnet cooperates with the electromagnet, a plurality of clamping plates are arranged in a rectangular array on the side wall of the notch, and the lower ends of the clamping plates are arranged obliquely; a plurality of plates are annularly distributed and arranged at the lower end of the base, and a through groove is arranged inside the plates.

[0007] Preferably, a plurality of slide grooves are arranged inside the base, the plurality of slide grooves are distributed in a rectangular array, the slide grooves are communicated with the notches, and the clamping plates are slidably connected with the slide grooves.

[0008] Preferably, two springs are fixedly connected inside the slide groove, and ends of the springs are fixedly connected to the side walls of the clamping plate.

[0009] Preferably, a plurality of grooves are provided at the lower end of the base, the plurality of grooves are distributed in a ring array, and a rod body is fixedly connected inside the groove.

[0010] Preferably, the plate is rotatably connected to the rod body, a rubber pad is fixedly connected to the top of the groove, and the lower end of the rubber pad is in contact with the side wall of the plate.

[0011] Preferably, a clamping groove is provided at the end of the plate, and an elastic member is fixedly connected to the inner wall of the groove, and the elastic member cooperates with the clamping groove.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] 1. The operator rotates the plate out of the groove, and then passes the fastening bolts through the through groove to fix the plate, thereby fixing the base in the specified position. When the base needs to be dismantled and transported, the operator removes the fastening bolts, and then rotates the plate into the groove for storage. During the process of storing the plate into the groove, the side of the plate squeezes the elastic part, causing the elastic part to deform and slide into the slot, and the plate is clamped and fixed in the groove, thereby greatly saving storage space and avoiding space waste caused by the protrusions being placed randomly.

[0014] 2. After the base is fixed, the operator places the bolt on the upper end of the movable plate. The electromagnet is energized to generate magnetic force to attract the permanent magnet, causing the movable plate to slide down to the inside of the slot. At the same time, the bolt slides into the slot to position the bolt. In the process of the movable plate sliding down to the inside of the slot, the clamp is pushed out of the slide groove by the elasticity of the spring, so that the clamp clamps the bolt, thereby further fixing the bolt, improving the positioning accuracy of the bolt, and preventing it from shifting during the processing process.

In the process of the movable plate 4 sliding downward to the inside of the slot 2, multiple clamps 7 slide out from the side wall of the slot 2 to clamp the bolt. When the bolt is processed, the electromagnet 3 is powered off to repel the permanent magnet 5, so that the permanent magnet 5 pushes the movable plate 4 to slide upward, thereby ejecting the processed bolt. In the process of the movable plate 4 sliding upward, the side of the movable plate 4 contacts the inclined wall set at the lower end of the clamp 7, so that the clamp 7 slides to the inside of the side wall of the slot 2.

[0022] A plurality of slide grooves 6 are arranged inside the base 1, and the plurality of slide grooves 6 are distributed in a rectangular array. The slide grooves 6 are connected to the notch 2, and the splint 7 is slidably connected to the slide grooves 6.

[0025] The plate 12 is rotatably connected to the rod body 11 , a rubber pad is fixedly connected to the top of the groove 9 , and the lower end of the rubber pad is in contact with the side wall of the plate 12 , so that the plate 12 is stored in the groove 9 .

[0026] A card slot 14 is provided at the end of the plate 12, and an elastic member 10 is fixedly connected to the inner wall of the groove 9. The elastic member 10 cooperates with the card slot 14. When the plate 12 is received in the groove 9, the side of the plate 12 squeezes the elastic member 10, so that the elastic member 10 deforms and slides into the card slot 14, thereby locking and fixing the plate 12 in the groove 9.

[0027] In the utility model, the operator rotates the plate 12 out of the groove 9, and then passes the fastening bolts through the through groove 13 to fix the plate 12, thereby fixing the base 1 at a specified position. When the base 1 needs to be dismantled and transported, the operator removes the fastening bolts, and then rotates the plate 12 into the groove 9 for storage. During the process of storing the plate 12 into the groove 9, the side of the plate 12 squeezes the elastic member 10, so that the elastic member 10 deforms and slides into the slot 14, thereby locking and fixing the plate 12 in the groove 9.
