Automobile bolt thread rolling equipment

Abstract

The utility model relates to a bolt thread rolling device for automobiles, aiming to solve the problem that the thread rolling machine thread plates in current precision screw production are fixed with bolts, and the thread rolling plates are difficult to replace by subsequently removing the bolts. However, the bolts need to be screwed with the aid of tools during installation and removal, and since a large number of bolts are required, more time and manpower are required during assembly and removal, resulting in inconvenience in replacing the thread rolling plates, thereby reducing production efficiency. The utility model includes a machine base, and a driving mechanism is provided on the surface of the machine base. The utility model pulls a handle outward so that the horizontal open end of the handle gradually moves away from the inside of the thread rolling plate, thereby facilitating rapid removal of the thread rolling plate. Similarly, the thread rolling plate required for use is placed inside a first mounting frame on the basis of pulling the handle outward, and then the handle is released. Under the influence of the spring rebound force, the horizontal open end of the handle is directly inserted into the inside of the thread rolling plate, thereby effectively realizing rapid installation of the thread rolling plate.

Description

Technical Field

[0001] The utility model relates to the technical field of automobile bolt production, in particular to automobile bolt thread rolling equipment. Background Art

[0002] Bolts are closely related to our daily life. Bolts are used in many products in many fields, and the automotive field is no exception. The production steps of bolts are roughly as follows: wire drawing (film treatment), forming, grinding, thread rolling, polishing, inspection and packaging.

[0003] A thread rolling machine is a device used to process the outer surface of a cylindrical workpiece. The main components of the thread rolling machine are composed of two identical thread rolling plates. The thread rolling plates have the same tooth shape and helix angle as the bolt thread. When the thread rolling plates move against each other, the bolt blank between the two thread rolling plates is threaded. One bolt thread is processed after the thread rolling plates move back and forth once. The speed is quite high. Usually, thread rolling plates of different sizes are replaced as required during use.

[0004] The utility model discloses a thread rolling machine tooth plate for precision screw production, comprising a machine base, a connecting column is provided at the center position of a rotating wheel, a small gear is provided at the other end of the connecting column, a supporting arm is also provided on the connecting column, a second rotating shaft is provided at one end of the supporting arm, a large gear is installed on the second rotating shaft, a third rotating shaft is provided at one edge of the large gear, a telescopic rod is provided on the third rotating shaft, a groove is provided on the machine base, a first thread plate is provided in the groove, a mounting seat is also provided on the machine base, and a mounting groove is provided on one side of the mounting seat. When the rotating wheel of the thread rolling machine rotates, the small gear on the connecting column rotates accordingly. Since the small gear is meshed with the large gear, the tooth pattern in the thread plate can roll the wire material to complete the thread rolling process of the screw. Different thread plates can be replaced by removing the second bolt above the first thread plate and the first bolt in the mounting seat, thereby solving the problem that the thread rolling plate of the thread rolling machine is inconvenient to replace.

[0005] However, the above-mentioned thread rolling machine die plate for precision screw production still has some shortcomings:

[0006] Although the threading plate of the thread rolling machine used for precision screw production is fixed with bolts, the problem of inconvenient replacement of the threading plate can be solved by removing the bolts later. However, the bolts need to be screwed with tools during installation and removal. At the same time, since a large number of bolts are required, more time and manpower are required for disassembly and assembly, resulting in inconvenience in replacing the threading plate, which reduces production efficiency. In view of this, we propose a bolt thread rolling equipment for automobiles. Utility Model Content

At the same time, since a large number of bolts are required, more time and manpower are required for disassembly and assembly, resulting in the inconvenience of replacing the thread plates, thereby reducing the production efficiency.

A set of limiting rings 503 are fixed on the surface of the handle 502, and a spring 504 is connected to one side of the limiting ring 503. The utility model pulls the handle 502 outward so that the horizontal open end of the handle 502 gradually moves away from the inside of the tooth-rubbing plate 8, which facilitates the rapid disassembly of the tooth-rubbing plate 8. Similarly, on the basis of pulling the handle 502 outward, the tooth-rubbing plate 8 to be used is placed inside the first mounting frame 4, and then the handle 502 is released. Under the influence of the rebound force of the spring 504, the horizontal open end of the handle 502 is directly stuck in the inside of the tooth-rubbing plate 8, which effectively realizes the rapid installation of the tooth-rubbing plate 8.

[0029] It is worth noting that the driving mechanism 2 includes a motor box 201, a motor is provided inside the motor box 201, the movable end of the motor is connected to the turntable 202, a first hinge frame 203 is provided on the surface of the turntable 202, a connecting rod 204 is clamped on the inner side of the first hinge frame 203, and a second hinge frame 205 is provided at one end of the connecting rod 204 away from the first hinge frame 203, wherein the two ends of the connecting rod 204 can rotate along the first hinge frame 203 and the second hinge frame 205 respectively.

[0031] Working principle: the staff pulls the handle 502 outward so that the horizontal open end of the handle 502 gradually moves away from the inside of the rubbing plate 8. At this time, the original rubbing plate 8 can be pulled out of the first mounting frame 4 to complete the disassembly. Similarly, the required rubbing plate 8 is placed inside the first mounting frame 4 on the basis of pulling the handle 502 outward, and then the handle 502 is released.
