Description

Technical Field

[0001] This utility model relates to the field of torsion bar manufacturing technology, and in particular to a clamping structure for a clamping plate shaft torsion bar. Background Technology

[0002] Torsion bars are key components widely used in automobiles and military equipment, playing a crucial role, especially in suspension systems. They are primarily made of high-strength, high-elasticity alloy materials, such as spring steel, exhibiting excellent fatigue and impact resistance. One end of the torsion bar is typically fixed to the vehicle frame or body, while the other end is connected to the suspension's control arm. When the wheels bounce up and down under external forces, the control arm causes the torsion bar to torsion, thereby absorbing and storing energy, thus providing cushioning and shock absorption.

[0003] In the existing technology, during the production process of torsion bars, clamping shafts are used to clamp the torsion bars. Currently, the clamping operation of torsion bars is mainly carried out manually. This process is not only time-consuming and labor-intensive with low clamping efficiency, but also prone to unexpected situations, such as the clamping shaft coming loose when clamping the torsion bar. This can cause the torsion bar to bounce under the reset force, potentially causing injury to workers and posing a certain danger. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where, during the production of torsion bars, a clamping shaft is needed to clamp the torsion bar. Currently, the clamping operation of torsion bars is mainly carried out manually. This process is not only time-consuming and labor-intensive with low clamping efficiency, but also prone to accidents, such as the clamping shaft coming loose during clamping. This can cause the torsion bar to bounce under the reset force, potentially injuring workers and posing a certain degree of danger.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a clamping plate shaft torsion bar clamping structure, comprising: a bracket, and further comprising:

[0006] A square groove 1 is formed on one side of the bracket. Two square grooves 2 are symmetrically formed on one side of the bracket. A U-shaped frame is slidably connected inside the two square grooves 2. A vertical plate is fixedly connected to the opposite side of each U-shaped frame. Two arc-shaped blocks are symmetrically fixedly connected to one side of each vertical plate. A lead screw is rotatably connected to the opposite side of the inner wall of the square groove 1. A threaded plate is threaded to the outer surface of the lead screw. Two retaining frames 1 are symmetrically fixedly connected to the bottom of the threaded plate. A motor is fixedly connected to the top of the bracket. The output end of the motor is fixedly connected to one end of the lead screw. Two retaining frames 2 are symmetrically fixedly connected to the top of the bracket.

[0007] Preferably, the outer surface of the threaded plate is slidably connected to the inside of the square groove, and the width of the threaded plate is equal to the width of the inner wall of the square groove.

[0008] Preferably, guide rods are fixedly connected to opposite sides of the inner wall of the square groove, and the U-shaped frame is slidably connected to the two guide rods.

[0009] Preferably, the outer surface of the guide rod two is provided with a spring three, which is fixedly connected to the bracket and the U-shaped frame respectively.

[0010] Preferably, each of the vertical plates has a sliding groove on its opposite side, and a guide rod is fixedly connected to the opposite side of the inner wall of the sliding groove. A movable frame is slidably connected inside the sliding groove, and the movable frame is slidably connected to the guide rod.

[0011] Preferably, a spring is provided on the outer surface of the guide rod, and the spring is fixedly connected to the movable frame and the vertical plate respectively.

[0012] Preferably, a movable rod is slidably connected to one side of the movable frame, a limit plate is fixedly connected to one end of the movable rod, and a second spring is provided on the outer surface of the movable rod. The second spring is fixedly connected to the limit plate and the movable frame respectively.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model controls the motor to start via a controller, causing its output shaft to drive the lead screw to rotate. Then, with the screw threaded connection between the lead screw and the threaded plate, and with the limiting and guiding action of a pair of threaded plates in the square groove, the threaded plate can move downward along the outer surface of the lead screw, simultaneously driving the clamping frame to move downward. The clamping frame then fits onto the other clamping plate, applying a downward force to press the torsion bar into the two clamping plates. This allows for the simultaneous pressing of two torsion bars, saving time and effort, thus improving the efficiency of torsion bar pressing. Furthermore, the limiting action of the arc-shaped block prevents the torsion bar from detaching and bouncing, improving the safety of the torsion bar pressing operation.

[0015] 2. In this utility model, under the reset force of the second spring, the movable rod can drive the limiting plate to move towards another clamping plate, clamping and limiting the other clamping plate, keeping the other clamping plate stable. This facilitates the subsequent pressing operation of the other clamping plate and the torsion bar, allowing it to be smoothly inserted into the first clamping frame to achieve a certain positioning effect.

[0025] Furthermore, such as Figure 1-4 As shown, the outer surface of the threaded plate 105 is slidably connected to the inside of the square groove 101. The width of the threaded plate 105 is equal to the width of the inner wall of the square groove 101. Through the above-mentioned arrangement, the threaded plate 105 is limited and guided.

[0026] Furthermore, such as Figure 1-4 As shown, guide rods 210 are fixedly connected to the opposite side of the inner wall of the square groove 2 102. The U-shaped frame 2 is slidably connected to the two guide rods 210. With the cooperation of the U-shaped frame 2 and the guide rods 210 slidingly connected, the U-shaped frame 2 can move up and down a certain distance, so as to adapt to the clamping operation of torsion bars of different lengths.

[0027] Furthermore, such as Figure 1-4 As shown, a spring 211 is provided on the outer surface of the guide rod 210. The spring 211 is fixedly connected to the bracket 1 and the U-shaped frame 2 respectively. Under the reset force of the spring 211, the U-shaped frame 2 can be supported and reset to a certain extent.

[0028] Furthermore, such as Figure 1-4 As shown, each of the opposite sides of the vertical plate 201 is provided with a sliding groove 203. A guide rod 204 is fixedly connected to the opposite side of the inner wall of the sliding groove 203. A movable frame 206 is slidably connected inside the sliding groove 203. The movable frame 206 is slidably connected to the guide rod 204. With the above arrangement, the movable frame 206 can slide along the outer surface of the guide rod 204.

[0029] Furthermore, such as Figure 1-4 As shown, a spring 205 is provided on the outer surface of the guide rod 204. The spring 205 is fixedly connected to the movable frame 206 and the vertical plate 201 respectively. Under the reset force of the spring 205, the movable frame 206 and the limiting plate 208 can be reset.

[0030] Furthermore, such as Figure 1-4 As shown, a movable rod 207 is slidably connected to one side of the movable frame 206. A limit plate 208 is fixedly connected to one end of the movable rod 207. A second spring 209 is provided on the outer surface of the movable rod 207. The second spring 209 is fixedly connected to the limit plate 208 and the movable frame 206 respectively.

[0031] Working principle: In use, as shown in the figure, one of the clamping plates is placed inside the clamping frame 107, and the torsion bar is clamped inside the two arc-shaped blocks 202. The arc-shaped blocks 202 limit and fix the torsion bar. One end of the torsion bar is inserted into the groove of one of the clamping plates to engage, so that the other clamping plate is fitted onto the other end of the torsion bar. Under the restoring force of the spring 209, the movable rod 207 can drive the limiting plate 208 to move towards the other clamping plate, clamping and limiting the other clamping plate and keeping it stable. This facilitates subsequent clamping operations on the other clamping plate and torsion bar, allowing for smooth insertion into the clamping frame 106 to achieve a certain positioning effect. Then, the controller starts the motor 104, causing its output shaft to drive the lead screw 103 to rotate. With the threaded connection between the lead screw 103 and the threaded plate 105, and the limiting and guiding effect of the square groove 101 on the threaded plate 105, the threaded plate 105 can move downwards along the outer surface of the lead screw 103, simultaneously driving the clamping frame 106 downwards, thus allowing the clamping frame 106 to... The clamping frame 106 is placed on top of another clamping plate, and a downward force is applied to press the torsion bar into both clamping plates. This allows for simultaneous pressing of two torsion bars, saving time and effort and improving the efficiency of torsion bar pressing. Furthermore, the limiting action of the arc-shaped block 202 prevents the torsion bar from detaching and bouncing, improving the safety of the torsion bar pressing operation. When the clamping frame 106 is placed on the other clamping plate, it contacts the limiting plate 208, applying a downward pressure to the limiting plate 208, thus controlling the movement of the frame. 206 slides downward along the outer surface of the guide rod 204, simultaneously compressing the spring 205. Under the reset force of the spring 205, the movable frame 206 and the limiting plate 208 can be reset. With the sliding connection between the U-shaped frame 2 and the guide rod 210, the U-shaped frame 2 can move up and down a certain distance, thus adapting to the clamping operation of torsion bars of different lengths. Under the reset force of the spring 211, the U-shaped frame 2 can be supported and reset to a certain extent.
