Description

Technical Field

[0001] This utility model relates to the field of transmission shaft manufacturing technology, specifically a transmission shaft production cutting mechanism. Background Technology

[0002] A drive shaft is a mechanical transmission component with wide applications in many fields, including automobiles, construction machinery, agricultural machinery, and industry. It is an indispensable and important component in mechanical transmission systems.

[0003] A search revealed a transmission shaft production cutting mechanism disclosed in Chinese Patent Publication No. CN220006228U. This utility model not only clamps the tail end of the raw material bar through an anti-vibration mechanism and fixes the position of the tail end of the raw material bar through a guide rod and a slide cylinder, thus improving the anti-vibration effect of the device, but also clamps the front end of the raw material bar through a pressing mechanism, thus improving the clamping effect of the device, and also initially fixes the raw material bar through a positioning mechanism, thus improving the pressing effect of the device.

[0004] However, similar to the aforementioned transmission shaft production cutting mechanism, it is generally impossible to clean the fixture and workpiece, which may result in dust, oil, metal shavings and other impurities at the clamping position. These impurities will affect the tightness of the contact between the fixture and the part, leading to inaccurate positioning and consequently affecting the subsequent processing quality of the workpiece. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The aforementioned background technology addresses the shortcomings and defects of existing technologies, such as the inability to clean fixtures and workpieces, which affects the tightness of contact between fixtures and parts, leading to inaccurate positioning and impacting processing quality.

[0006] The transmission shaft production cutting mechanism disclosed in this utility model includes a mounting plate, a clamping assembly on the mounting plate, a sleeve on one side of the clamping assembly, a cleaning cotton installed at one end of the sleeve, a drive plate installed at the other end of the sleeve, an elastic assembly between the drive plate and the mounting plate, a support frame below the drive plate, and a limit assembly between the support frame and the drive plate.

[0007] Furthermore, the elastic component includes a tension spring, one end of which is mounted on the drive plate and the other end of which is disposed on the mounting plate. A telescopic rod is disposed on the inner side of the tension spring, and both ends of the telescopic rod are respectively mounted on the drive plate or the mounting plate.

[0008] Furthermore, two tension springs are provided, and the two tension springs are symmetrically arranged on both sides of the sleeve.

[0009] Furthermore, the limiting component includes a limiting block, which is slidably mounted on the support frame. The upper end of the limiting block is chamfered, and a pressure plate is provided at the lower end of the limiting block. A reset component is provided between the pressure plate and the mounting plate.

[0010] Furthermore, the reset assembly includes a vertical rod mounted on the mounting plate, one end of the vertical rod passing through the pressure plate, and a spring provided on the vertical rod between the pressure plate and the mounting plate.

[0011] Furthermore, the clamping assembly includes clamping plates, and two clamping plates are provided. The two clamping plates are slidably disposed on the mounting plate. A bidirectional threaded rod is provided between the two clamping plates and the mounting plate. The bidirectional threaded rod is rotatably mounted on the mounting plate and is threadedly connected to the clamping plates.

[0012] Furthermore, a guide rail is provided below the mounting plate, and a two-way threaded rod is provided between the guide rail and the mounting plate. A baffle is installed at one end of the support frame.

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

[0014] 1. This utility model, by incorporating a drive plate, cleaning cotton, sleeve, and elastic components, controls the limiting component to release the restriction on the drive plate during operation. Under the action of the elastic component, the drive plate moves, causing the sleeve and cleaning cotton to follow suit. The sleeve is then moved to the center of the clamping assembly, whereupon the workpiece is passed through the sleeve, which is then driven to rotate. The cleaning cotton on the outer side of the sleeve cleans the clamping assembly, while the cleaning cotton on the inner side of the sleeve cleans the clamping position of the workpiece, effectively removing surface impurities and ensuring a closer fit between the fixture and the workpiece, thereby improving positioning accuracy and processing quality.

[0015] 2. This utility model is equipped with components such as springs, vertical rods, pressure plates, and baffles. During operation, the spring components and vertical rod components cooperate with each other to push the moved pressure plate to automatically reset. This allows the limiting block component to automatically restrict the position of the drive plate, and the baffle component restricts the movement of the drive plate. In cooperation with the limiting block, it plays a certain clamping and limiting role, thereby improving the stability of the drive plate. Attached Figure Description

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 4 As shown, the transmission shaft production cutting mechanism of this utility model includes a mounting plate 1, a clamping assembly 2 on the mounting plate 1, a sleeve 3 on one side of the clamping assembly 2, a cleaning cotton 5 installed at one end of the sleeve 3, a drive plate 4 installed at the other end of the sleeve 3, an elastic assembly 6 between the drive plate 4 and the mounting plate 1, a support frame 7 below the drive plate 4, a limit assembly 8 between the support frame 7 and the drive plate 4, a guide rail 9 below the mounting plate 1, and a bidirectional threaded rod 10 between the guide rail 9 and the mounting plate 1. The device is installed on the cutting equipment through the guide rail 9.

[0024] During operation, the limiting component 8 is first used to release the restriction on the drive plate 4. Then, the elastic component 6 controls the drive plate 4 to move. The drive plate 4 drives the sleeve 3 and cleaning cotton 5 to move together, and moves the sleeve 3 to the middle of the clamping component 2. Then, the two ends of the part are inserted into the corresponding sleeve 3 and the sleeve 3 is driven to rotate. The sleeve 3 drives the cleaning cotton 5 to rotate together. The cleaning cotton 5 on the inner side of the sleeve 3 cleans the surface of the part, and the cleaning cotton 5 on the outer side of the sleeve 3 cleans the clamping component 2. After cleaning, the drive plate 4 is pushed to move in the direction of the limit component 8 and the position of the drive plate 4 is limited by the limiting component 8. The part is clamped and fixed by the clamping component 2. After fixing, the part is processed by the cutting equipment.

[0025] like Figure 2 , Figure 3 As shown, the elastic component 6 includes a tension spring 601. One end of the tension spring 601 is mounted on the drive plate 4, and the other end of the tension spring 601 is mounted on the mounting plate 1. A telescopic rod 602 is provided on the inner side of the tension spring 601. The two ends of the telescopic rod 602 are respectively mounted on the drive plate 4 or the mounting plate 1. When the restriction on the drive plate 4 is released, the tension spring 601 drives the drive plate 4 to move towards the clamping component 2. The operator pushes the drive plate 4 to move in the direction of tension, thereby stretching and storing the tension spring 601.

[0026] Two tension springs 601 are provided, and the two tension springs 601 are symmetrically arranged on both sides of the sleeve 3, so that the force on both sides of the drive plate 4 is even, thereby improving the stability of the device during operation.

[0027] The limiting component 8 includes a limiting block 801, which is slidably mounted on the support frame 7. A baffle 11 is installed at one end of the support frame 7. The upper end of the limiting block 801 is chamfered, and a pressure plate 802 is provided at the lower end of the limiting block 801. A reset component is provided between the pressure plate 802 and the mounting plate 1. When the operator drives the pressure plate 802 to move downward, the pressure plate 802 drives the limiting block 801 to move accordingly. When the limiting block 801 separates from the drive plate 4, the restriction on the drive plate 4 is released.

[0028] like Figure 3 As shown, the reset assembly includes a vertical rod 804, which is mounted on the mounting plate 1. One end of the vertical rod 804 passes through the pressure plate 802. A spring 803 is provided on the vertical rod 804 between the pressure plate 802 and the mounting plate 1. When the pressure plate 802 moves downward, it compresses the spring 803, and the spring 803 releases the force to push the pressure plate 802 upward. The pressure plate 802 drives the limit block 801 to reset.

[0029] like Figure 2As shown, the clamping assembly 2 includes two clamping plates 201. The two clamping plates 201 are slidably mounted on the mounting plate 1. A bidirectional threaded rod 202 is provided between the two clamping plates 201 and the mounting plate 1. The bidirectional threaded rod 202 is rotatably mounted on the mounting plate 1 and is threadedly connected to the clamping plates 201. The operator drives the bidirectional threaded rod 202 to rotate, which drives the two clamping plates 201 to move relative to each other. When the two clamping plates 201 are close to each other, the part is clamped. When the two clamping plates 201 are driven to move away from each other, the part is released from the fixation.

[0030] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
