Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a thread rolling machine for irregularly shaped bolts. Background Technology

[0002] Thread rolling is a thread processing technology. Because the rolled threads have high strength and good toughness, this processing technology is often used for thread processing of high-end parts.

[0003] For example, Chinese patent CN221184561U discloses a thread rolling machine. This utility model belongs to the field of mechanical processing technology, and in particular to a thread rolling machine. It includes a power distribution box, on the top of which multiple support rods are fixedly provided. The top of the multiple support rods is fixedly provided with the same worktable. A clamping platform is movably provided on the top of the worktable. A drive motor is provided on the top of the worktable. This utility model sets up a locking block, a locking groove, and an outer sleeve. When changing the rolling cutter, the outer sleeve is held and rotated counterclockwise. The outer sleeve drives the rolling cutter and the internal locking groove to rotate. When the outer sleeve can no longer rotate, the locking block moves to the longitudinal groove of the locking groove. The spring applies a pushing force to the rotating shaft, and the rolling cutter is pushed out. Then, the new rolling cutter is taken out, and then the outer sleeve is installed on the rotating shaft. The locking block is inserted into the locking groove, and then the outer sleeve is rotated clockwise to complete the installation of the rolling cutter. The locking method replaces the traditional bolt pressing and fixing mode, improving the replacement efficiency.

[0004] The aforementioned patent has the following problems:

[0005] The patent has some drawbacks in use, such as: when clamping and fixing bolts, the above device can only fix bolts of a single type and cannot clamp irregularly shaped bolts, which may result in unstable clamping and affect subsequent operations. Furthermore, when thread rolling bolts, the rolling cutter cannot be adjusted and cannot be adapted to bolts of any size. In view of this, we propose a thread rolling machine for irregularly shaped bolts. Utility Model Content

[0006] The purpose of this invention is to provide a thread rolling machine for irregularly shaped bolts to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a thread rolling machine for irregularly shaped bolts, comprising:

[0009] A trapezoidal plate is slidably mounted on the top surface of a mounting platform. A drive shaft is rotatably mounted on the top surface of the trapezoidal plate. A fixed platform is fixedly mounted on one end of the drive shaft. A fixed plate is fixedly mounted on one side of the fixed platform. Multiple rolling knives are slidably mounted on one side of the fixed plate.

[0010] An adjustment assembly is disposed within a fixed plate and is used to adjust the movement of multiple rolling cutters.

[0011] In the above technical solution, the adjusting component further includes multiple sliders, each slider being slidably mounted inside a fixed plate. One side of each slider is fixedly connected to one side of each rolling cutter. Each slider has a one-way threaded rod threaded inside it, with the threads on the one-way threaded rods all rotating clockwise. One end of each one-way threaded rod is rotatably connected to the inner bottom surface of the fixed plate. A first bevel gear is fixedly mounted on the outer wall of each one-way threaded rod.

[0012] In the above technical solution, the adjustment component further includes multiple fixing blocks, which are evenly distributed and fixedly installed on the outer side wall of the fixing platform. A gear column is rotatably installed on one side of each fixing block, and a second bevel gear is fixedly installed on one side of each gear column. The second bevel gears mesh with the first bevel gears respectively. The same toothed ring is rotatably installed on the outer side wall of each fixing block, and the inner wall of the toothed ring meshes with the outer side wall of each gear column respectively. A fixing box is fixedly installed on the other side of one of the fixing blocks, and a third motor is fixedly installed inside the fixing box. One end of the output shaft of the third motor is fixedly connected to the other side of one of the gear columns.

[0013] In the above technical solution, further, a mounting base is fixedly installed on one side of the mounting box, and a bidirectional threaded rod is rotatably installed in the mounting base. The two threads on the bidirectional threaded rod have opposite directions of rotation. Two threaded blocks are threadedly installed on the outer wall of the bidirectional threaded rod. The top surfaces of the two threaded blocks are fixedly connected to the bottom surfaces of the two sliding plates respectively. A first motor is fixedly installed on the top surface of the mounting platform. One end of the output shaft of the first motor passes through one side of the mounting box and is fixedly connected to one end of the bidirectional threaded rod.

[0014] In the above technical solution, a second motor is further fixedly installed on the top surface of the trapezoidal plate, and one end of the output shaft of the second motor is fixedly connected to one side of the transmission shaft.

[0015] In the above technical solution, the top surface of the mounting platform is provided with an opening groove, which is located below the fixed platform. An inclined plate is fixedly installed in the opening groove, and a collection box is provided below the inclined plate. The bottom surface of the collection box is fixedly connected to the top surface of the battery box, and a sliding box is slidably installed in the collection box.

[0016] In the above technical solution, the top surface of the mounting platform is provided with a sliding groove, the bottom surface of the sliding groove is fixedly installed with a telescopic cylinder, the bottom surface of the trapezoidal plate is fixedly installed with a mounting block, and one end of the telescopic cylinder is fixedly connected to the outer side wall of the mounting block.

[0017] In the above technical solution, furthermore, multiple support legs are fixedly installed on the bottom surface of the battery storage box.

[0018] The beneficial effects of this utility model are:

[0019] 1. This thread rolling machine for irregularly shaped bolts, when rolling threads on the bolt, activates a telescopic cylinder after the bolt is clamped and fixed. The telescopic cylinder pulls a trapezoidal plate according to the bolt length, moving the trapezoidal plate to a suitable position so that the tail of the bolt enters the fixed plate. At this time, the third motor is activated, driving one of the gear columns to rotate. The gear column meshes with the gear on the inner side of the gear ring. The second bevel gear on one side of the gear column meshes with the first bevel gear. The first bevel gear drives the one-way thread rod to rotate, thereby driving multiple fixed platforms to move. The movement is adjusted according to the thickness of the bolt tail until the multiple fixed platforms are in contact with the bolt tail. Finally, the second motor is activated, driving the transmission shaft to rotate. The multiple fixed platforms roll and engrave threads on the surface of the bolt. After the bolt processing is completed, the first motor is controlled to contact the bolt limit position, and the bolt falls into the open groove and slides into the sliding box by the inclined plate. This structure solves the problem that the rolling cutter cannot be adjusted when rolling threads on bolts, and cannot be adapted to bolts of any size. It is simple and practical.

[0020] 2. The thread rolling machine for irregular bolts allows the worker to manually place the unprocessed bolt between two sliding plates during operation. The first motor is then started, driving a bidirectional threaded rod to rotate. Two threaded blocks slide on the rod, moving the two sliding plates. The semi-circular plates on the sliding plates move closer together until multiple small semi-circular plates completely clamp the bolt. This structure can accommodate bolts of any shape, solving the problem of only being able to fix single-type bolts and being unable to clamp irregular bolts, which could lead to unstable clamping. This offers practical advantages. Attached Figure Description
