Description

Technical Field

[0001] The utility model relates to the technical field of thread rolling machines, in particular to a high-stability transmission device for bolt thread rolling. Background Art

[0002] The thread rolling machine is a kind of mechanical processing equipment specially used for producing threaded fasteners and connectors. The main purpose of the thread rolling machine is to make various metal materials into threaded parts of different specifications and types. It is widely used in machinery, construction, transportation, electronics and other fields. The working principle of the thread rolling machine is to roll cylindrical raw materials into threaded parts of various specifications by rolling.

[0003] When the thread rolling machine is in use, the movable thread rolling plate is driven to reciprocate by the transmission device. When the bolt is transmitted between the movable thread rolling plate and the static thread rolling plate, the movable thread rolling plate and the static thread rolling plate cooperate to realize the thread rolling operation on the bolt. In the prior art, the movable thread rolling plates used in the thread rolling machine are all slidably installed through the slide groove. Since there is no component to intervene in the movable thread rolling plate, the movable thread rolling plate is prone to up and down movement when reciprocating in the slide groove, which makes the movable thread rolling plate prone to instability and jamming, affecting the bolt processing quality. Therefore, it is necessary to design a high-stability transmission device for bolt thread rolling to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a high-stability transmission device for bolt thread rolling.

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

[0006] The cam is provided with a slidable arm for holding the movable thread rolling plate in the upright position, and a cam is provided on the upper end face of the cam, and a cam is provided on the lower end face of the cam, and a cam is provided on the lower end face of the cam, and a cam is provided on the lower end face of the cam.

[0007] Preferably, the connection mechanism comprises a connection rod fixedly mounted on the outer wall of the stabilizing sleeve, and the end of the connection rod is fixedly connected to the upper end surface of the movable thread rolling plate.

[0008] Preferably, the limiting mechanism comprises a limiting rod fixedly installed between the two connecting blocks, and the limiting rod slides through the two buffer sleeves.

[0009] Preferably, the buffer mechanism comprises a buffer spring installed on the outer wall of the slide rod, and two ends of the buffer spring are elastically connected to the outer wall of the connecting block and the inner wall of the buffer sleeve respectively.

[0010] Preferably, the connection mechanism comprises a connection plate rotatably mounted inside the first connection frame, and an end of the connection plate is rotatably connected to the inside of the second connection frame.

[0011] Preferably, the elastic mechanism comprises two spring telescopic rods fixedly mounted on the upper end surface of the base, and the telescopic ends of the two spring telescopic rods are fixedly connected to the bottom wall of the thread rolling machine.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting components such as a stabilizer bar, a stabilizer sleeve and a connecting rod, the movable thread rolling plate can be restricted when moving under the cooperation of the stabilizer bar and the stabilizer sleeve, which can effectively prevent the movable thread rolling plate from moving up and down, thereby increasing the stability of the movable thread rolling plate when moving and avoiding affecting the processing quality of the bolts.

[0014] 2. By setting up components such as a buffer sleeve, a sliding rod and a buffer spring, the buffer sleeve can squeeze the buffer spring during the sliding process, so that the buffer spring is deformed by force to absorb the force. When the buffer spring releases its elastic potential energy to drive the buffer sleeve to move and reset, the force generated by the vibration can be buffered, thereby increasing the stability of the thread rolling machine during operation.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A high-stability transmission device for bolt thread rolling comprises a thread rolling machine 1 and a base 2, a moving thread rolling plate 3 is slidably mounted on the upper end surface of the thread rolling machine 1, a stabilizing rod 5 is fixedly mounted on the upper end surface of the thread rolling machine 1 through a stabilizing frame 4, a stabilizing sleeve 6 is slidably mounted on the outer wall of the stabilizing rod 5, and the outer wall of the stabilizing sleeve 6 is fixedly connected to the upper end surface of the moving thread rolling plate 3 through a connecting mechanism, the connecting mechanism comprises a connecting rod 7 fixedly mounted on the outer wall of the stabilizing sleeve 6, the end of the connecting rod 7 is fixedly connected to the upper end surface of the moving thread rolling plate 3, two connecting blocks 8 are fixedly mounted on the upper end surface of the base 2, and two sliding rods 9 are fixedly mounted between the two connecting blocks 8, Two buffer sleeves 11 are slidably installed on the outer walls of the two sliding rods 9 through a limiting mechanism. The limiting mechanism includes a limiting rod 10 fixedly installed between the two connecting blocks 8. The limiting rod 10 slides through the two buffer sleeves 11. The limiting rod 10 can limit the two buffer sleeves 11 so that the two buffer sleeves 11 can only move axially along the outer wall of the sliding rod 9. The outer walls of the two buffer sleeves 11 are connected to the outer wall of the connecting block 8 through the buffer mechanism. The buffer mechanism includes a buffer spring 12 installed on the outer wall of the sliding rod 9. The two ends of the buffer spring 12 are elastically connected to the outer wall of the connecting block 8 and the inner wall of the buffer sleeve 11 respectively.

[0023] A first connecting frame 13 is fixedly installed on the upper end surface of each buffer sleeve 11, and a second connecting frame 15 is rotatably installed inside the two opposite first connecting frames 13 through a connecting mechanism. The connecting mechanism includes a connecting plate 14 rotatably installed inside the first connecting frame 13, and the end of the connecting plate 14 is rotatably connected to the inside of the second connecting frame 15. The outer walls of the two second connecting frames 15 are fixedly connected to the bottom wall of the thread rolling machine 1, and the upper end surface of the base 2 is fixedly connected to the bottom wall of the thread rolling machine 1 through an elastic mechanism. The elastic mechanism includes two spring telescopic rods 16 fixedly installed on the upper end surface of the base 2, and the telescopic ends of the two spring telescopic rods 16 are fixedly connected to the bottom wall of the thread rolling machine 1.

[0024] When the utility model is used, in the process that the connecting rod transmission mechanism of the thread rolling machine 1 drives the movable thread rolling plate 3 to move, the movable thread rolling plate 3 can drive the stabilizing sleeve 6 to slide on the outer wall of the stabilizing rod 5 through the cooperation of the connecting rod 7. The cooperation of the stabilizing rod 5 and the stabilizing sleeve 6 can limit the movable thread rolling plate 3 when moving, and can effectively prevent the movable thread rolling plate 3 from moving up and down, thereby increasing the stability of the movable thread rolling plate 3 when moving, and avoiding affecting the processing quality of the bolts;

[0025] When the thread rolling machine 1 is running, the vibration generated by its motor and other transmission components can be transmitted to the second connecting frame 15, so that the second connecting frame 15 can transmit the force to the first connecting frame 13 through the cooperation of the connecting plate 14. The force on the first connecting frame 13 can drive the buffer sleeve 11 to slide on the outer wall of the slide rod 9 through the cooperation of the limit rod 10. The buffer sleeve 11 can squeeze the buffer spring 12 during the sliding process, so that the buffer spring 12 is deformed by the force to absorb the force. When the buffer spring 12 releases its elastic potential energy and drives the buffer sleeve 11 to move and reset, the force generated by the vibration can be buffered, thereby increasing the stability of the thread rolling machine 1 during operation. In the process of releasing the elastic potential energy of the buffer spring 12, the damping effect generated by the two spring telescopic rods 16 can absorb the elastic potential energy released by the buffer spring 12, without affecting the buffering and vibration reduction, and also avoiding the reciprocating vibration caused by resonance.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
