Description

Technical Field

[0001] This utility model belongs to the field of bolt processing technology, specifically relating to a bolt thread rolling tool. Background Technology

[0002] A bolt is a mechanical part, a cylindrical threaded fastener used with a nut. It consists of a head and a shank (a cylinder with external threads), and requires a nut to fasten two parts with through holes. This type of connection is called a bolted connection. Since the two parts can be separated by unscrewing the nut, a bolted connection is a detachable connection. A thread grinder is a thread-machining machine tool that uses a shaped grinding wheel as an abrasive to machine precision threads. In production, thread grinders are commonly used to machine the thread profile of bolts or taps.

[0003] Chinese patent document CN202420410079.4 discloses a capacitor aluminum shell bolt thread rolling machine, including a base plate, a symmetrically distributed inclined support frame above the base plate, an inclined plate fixedly connected above the inclined support frame, and electric cylinder mounting plates fixedly connected to both sides of the inclined plate. A gear frame fixedly connected above the base plate, a motor mounting plate fixedly connected to one side of the gear frame, and a stepper motor fixedly connected above the motor mounting plate. This utility model uses a stepper motor to drive a second helical gear and a rotating wheel to rotate synchronously. The second helical gear and the rotating wheel drive two sliding mounting plates to reciprocate through a connecting arm, so that the second thread rolling plate on one side of the two sliding mounting plates reciprocates synchronously, thereby synchronously rolling the two bolts to be processed between the first thread rolling plate and the second thread rolling plate.

[0004] However, while existing thread rolling machines have achieved the function of effectively producing and processing bolts, they still have some shortcomings. The first thread rolling plate is a fixed plate in the thread rolling process. Due to structural limitations, it cannot be adjusted laterally according to the size and model of the bolt to be rolled, thus changing the lateral distance between the first thread rolling plate and the relatively reciprocating second thread rolling plate. This results in the thread rolling machine having weak adaptability. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A bolt thread rolling fixture, comprising:

[0007] Thread rolling moving plate assembly;

[0008] The thread rolling stationary plate assembly is arranged parallel to the thread rolling moving plate assembly, and the distance between the two is not less than the diameter of the thread-rolling stud.

[0009] The power component is used to drive the moving plate assembly of the wire rolling process to reciprocate linearly relative to the fixed plate assembly of the wire rolling process;

[0010] A feeding assembly is disposed on the side of the wire rolling plate assembly;

[0011] The feeding channel sequentially feeds the bolts to one side of the pushing assembly. Under the action of the pushing assembly, the bolts enter the gap between the thread rolling moving plate assembly and the thread rolling stationary plate assembly.

[0012] The wire-rolling fixed plate assembly includes a fixed plate seat, a fixed plate body connected to the side of the fixed plate seat, and an adjustment mechanism. The adjustment mechanism drives the fixed plate seat to move along the spacing width direction so that the fixed plate body and the wire-rolling moving plate assembly move closer or further apart from each other.

[0013] Furthermore, the wire rolling plate assembly also includes a slide rail that is slidably connected to the plate holder.

[0014] Furthermore, the bottom of the fixed plate seat is provided with a dovetail groove that conforms to the shape of the slide rail.

[0015] Furthermore, the adjustment mechanism includes a mounting base, a handle, and a rotating rod that passes through the mounting base and is connected to the fixed plate base.

[0016] Furthermore, the connection between the fixed plate body and the fixed plate base is a mortise and tenon structure connection.

[0017] Furthermore, a discharge hopper is also provided on the side of the wire rolling plate assembly.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] The thread rolling stationary plate assembly used in this thread rolling fixture, based on the mechanical structure that meets the thread rolling operation process, can adjust the gap distance between the thread rolling stationary plate assembly and the thread rolling moving plate assembly by adjusting the lateral movement of the drive stationary plate seat and the stationary plate body through the adjustment mechanism, thereby matching the size of the bolt to be threaded and making it more adaptable.

[0027] like Figure 1 - Figure 3 As shown, the bolt thread rolling fixture of this utility model includes a thread rolling moving plate assembly 1, a thread rolling fixed plate assembly 2, a power assembly 3, and a material pushing assembly 4.

[0028] Among them, the thread rolling fixed plate assembly 2 and the thread rolling moving plate assembly 1 are arranged in parallel with each other, and the distance between them is not less than the diameter of the thread-rolling stud.

[0029] The power unit 3 is used to drive the moving plate assembly 1 to reciprocate linearly relative to the fixed plate assembly 2;

[0030] The pusher assembly 4 is located on the side of the thread rolling plate assembly 2;

[0031] A feeding channel 5 is provided on one side of the pushing assembly 4. The feeding channel 5 pushes the bolts 7 sequentially toward the pushing assembly 4. Under the action of the pushing assembly 4, the bolts 7 enter the gap between the thread rolling moving plate assembly 1 and the thread rolling stationary plate assembly 2.

[0032] The thread rolling stationary plate assembly 2 used in this thread rolling fixture, based on the mechanical structure that meets the thread rolling operation process, can adjust the gap distance between the thread rolling stationary plate assembly 2 and the thread rolling moving plate assembly 1 by adjusting the mechanism 22 to move the drive stationary plate seat 20 and the stationary plate body 21 laterally, thereby matching the size of the bolt 7 to be threaded and making it more adaptable.

[0033] Specifically, such as Figure 3 As shown, the wire rolling plate assembly 2 includes a plate base 20, a plate body 21 connected to the plate base 20, and an adjustment mechanism 22. The adjustment mechanism 22 drives the plate base 20 to move along the spacing width direction so that the plate body 21 and the wire rolling moving plate assembly 1 move closer or further apart from each other.

[0034] The thread rolling plate assembly 2 also includes a slide rail 23 that is slidably connected to the plate holder 20.

[0035] The slide rail 23 allows the wire rolling plate assembly 2 to move more smoothly in the lateral adjustment, resulting in better smoothness.

[0036] Specifically, the bottom of the fixed plate seat 20 is provided with a dovetail groove 200 that conforms to the slide rail 23. Compared with other groove structures, the dovetail groove 200 provides better tightness and is less prone to loosening. In addition, an oil filling hole connected to the dovetail groove 200 can be provided on the fixed plate seat 20 for easy addition of lubricant.

[0037] In this embodiment, the adjustment mechanism 22 can be driven by a screw assembly. Its structure includes a mounting base 220, a rotating handle 222, and a rotating rod 221 that passes through the mounting base 220 and connects to the fixed plate base 20. Of course, the adjustment mechanism 22 can also adopt other structural forms, such as a telescopic cylinder.

[0038] In this thread rolling plate assembly 2, the plate body 21 and the plate base 20 are connected by a mortise and tenon structure, or directly by bolts 7. No specific restrictions are made here.

[0039] In addition, a discharge hopper 6 is provided on the side of the thread rolling plate assembly 2. The function of the discharge hopper 6 is to guide the threaded bolts 7, so as to facilitate the centralized collection of the bolts 7 for the next processing step.

[0040] The aforementioned wire rolling plate assembly 1, power assembly 3, and pusher assembly 4 are all prior art. For specific structures and connection forms, please refer to the technical solutions mentioned in the background art, namely the patent document with application number CN202420410079.4.
