Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a combined positioning tooling fixture plate. Background Technique

[0002] A machined workpiece refers to the cutting, grinding or other physical processing of raw materials to make them into workpieces that meet requirements. The main equipment for machining workpieces is various machine tools, including lathes, milling machines, drilling machines, grinding machines, etc. According to different processing requirements, these devices can use different cutting methods and tools to obtain the best processing effect. Usually, when a workpiece is placed in a machine tool for processing, the workpiece is clamped and then processed. When processing circular workpieces such as round shafts, it is not only necessary to rotate limit structures such as bolts multiple times for fixation, but also prone to slipping, which is very inconvenient.

[0003] At present, when the existing fixture plates clamp round shaft workpieces, they usually use structures such as cross plates and bolts for clamping and limiting. The clamping process is very inconvenient. At the same time, since the surface of the round shaft workpiece is arc-shaped, it is prone to slipping during the processing process, reducing the clamping stability and convenience. At the same time, only one round shaft workpiece can be clamped at a time. When processing another round shaft workpiece, it needs to be disassembled and then clamped, which is very inconvenient and reduces work efficiency. Summary of the Invention

[0004] The main purpose of the utility model is to solve the above-mentioned existing technical problems and provide a combined positioning tooling fixture plate.

[0005] The specific scheme of the utility model is: a combined positioning tooling fixture plate, including a mounting plate. A clamping mechanism is provided at the top of the mounting plate. The clamping mechanism includes a fixing member and a clamping block a. The fixing member includes a mounting seat. The inside of the mounting seat is hollowed out. A driving mechanism is installed on the mounting seat. The output end of the driving mechanism is connected to a gear a. Both sides of the gear a are drivingly connected to a gear b. One end of the gear b is provided with a threaded tube. The end of the threaded tube away from the gear b penetrates through the mounting seat and is rotatably connected. A bearing b is sleeved on the surface of the threaded tube, so that the threaded tube can rotate. The bearing b is embedded in the inside of the mounting seat. The end of the threaded tube away from the gear b is provided with an opening. A threaded rod is in threaded connection with the threaded tube. One end of the threaded rod away from the threaded tube is provided with a clamping block b. The clamping block b is located on one side of the clamping block a. The clamping block a and the clamping block b are arc-shaped.

[0006] According to the above technical solution, the driving mechanism drives the gear a to rotate, the gear a drives the gear b to rotate, and when the gear b rotates, it drives the threaded tube to rotate in the bearing b, so that the threaded rod moves to one side in the threaded tube, thereby pushing the clamping block b to move for clamping. The arc-shaped clamping blocks can facilitate the clamping and processing of round shaft-shaped workpieces.

[0007] Further, the driving mechanism includes a rotating rod which vertically penetrates through and is rotatably connected to the mounting seat. The bottom of the rotating rod is connected to Gear A, and a connecting rod is connected to the bottom of Gear A. The top end of the mounting plate is inlaid with Bearing A, and Bearing A is located directly below Gear A. The bottom of the connecting rod is connected to Bearing A.

[0008] According to the above technical solution, the rotating rod drives Gear A to rotate within Bearing A, thereby achieving the driving effect.

[0009] Further, both Gear A and Gear B are bevel gears.

[0010] According to the above technical solution, the bevel gear arrangement is more in line with its transmission structure, further improving stability.

[0011] Further, multiple groups of clamping mechanisms are evenly distributed on the top end of the mounting plate.

[0012] According to the above technical solution, multiple groups of clamping mechanisms improve the processing efficiency, and one mounting plate can clamp multiple structures.

[0013] Further, there is a gap between the clamping block b and the mounting plate.

[0014] According to the above technical solution, the gap reduces the friction between the clamping block b and the mounting plate, improving the smoothness of movement.

[0015] Further, a rubber layer is provided on the surface of the clamping block b.

[0016] According to the above technical solution, the rubber layer reduces the friction on the workpiece during clamping, and at the same time can also play an anti-slip effect, improving the stability of clamping.

[0017] The present utility model has the following advantages compared with the prior art: This combined positioning tooling fixture plate combines multiple groups of clamping mechanisms, which can not only quickly and conveniently clamp and process circular shaft workpieces, avoiding traditional complex clamping methods, but also improve the wrapping property of the circular shaft during clamping through the arc-shaped clamping block, thereby improving the stability of circular shaft processing and avoiding sliding. At the same time, combining multiple groups of clamping mechanisms can improve work efficiency, clamping multiple circular shaft components at one time, avoiding the need to repeatedly disassemble and clamp circular shaft components, greatly improving the work efficiency and usability of the combined positioning tooling fixture plate.

[0025] Referring to the mounting plate 1-6, this embodiment is a combined positioning fixture plate, which is composed of a mounting plate 1 and a clamping mechanism and other structures. A clamping mechanism is installed on the top of the mounting plate 1, and the clamping mechanism includes a fixing member and a clamping block a2. The fixing member includes a mounting seat 3, and the mounting seat 3 is hollow inside. A driving mechanism is installed on the top of the mounting seat 3, and the driving mechanism is used to drive the gear a4 to rotate. The output end of the driving mechanism is fixedly connected to the gear a4, and the two sides of the gear a4 are transmission-connected to the gear b5. A threaded tube 6 is welded at one end of the gear b5, and the end of the threaded tube 6 away from the gear b5 passes through the mounting plate. The seat 3 is mounted and rotatably connected, and a bearing b7 is mounted on the surface of the threaded tube 6, so that the threaded tube 6 can rotate in the bearing b7. The bearing b7 is embedded and fixed inside the mounting seat 3 and is located on both sides of the hollow part of the mounting seat 3. The threaded tube 6 is provided with an opening at the end away from the gear and is hollowed out inside and provided with threads. It should also be noted that the threaded tube 6 can be purchased directly, and a threaded rod 8 is connected to the inner thread of the threaded tube 6. A clamping block b9 is welded at one end of the threaded rod 8 away from the threaded tube 6. The clamping block b9 is located parallel to one side of the clamping block a2. The clamping block a2 and the clamping block b9 are arc-shaped, so that they can clamp the round shaft workpiece more stably.

[0026] Furthermore, the driving mechanism includes a rotating rod 10, which is vertically inserted into the middle of the mounting seat 3 and rotatably connected. The bottom end of the rotating rod 10 is fixedly connected to the gear a4. The bottom end of the gear a4 is vertically fixedly connected to a connecting rod 11. A bearing a12 is inlaid on the top of the mounting plate 1. The bearing a12 is located directly below the gear a4. The bottom of the connecting rod 11 is connected to the bearing a12, thereby assisting the rotation of the gear a4.

[0027] Furthermore, gear a4 and gear b5 are both bevel gears, which make the transmission more stable.

[0028] Furthermore, multiple clamping mechanisms are evenly distributed at the top of the mounting plate 1, improving the clamping efficiency.

[0029] Furthermore, there is a gap between the clamping block b9 and the mounting plate 1, and the gap is maintained at 5 mm to 8 mm to avoid hard friction between the clamping block b9 and the mounting plate 1, improving the smoothness.

[0030] Furthermore, a rubber layer 13 is provided on the surface of the clamping block b9, reducing the wear on the surface of the round shaft workpiece during clamping and at the same time having an anti-slip effect.

[0031] The working principle of this embodiment is as follows: When installing the round shaft workpiece, first place the workpiece between the clamping block a2 and the clamping block b9. By rotating the rotating rod 10, the gear a4 is driven to rotate. When the gear a4 rotates, it meshes with the gear b5 to drive the two side gears b5 to rotate. The gear b5 drives the threaded tube 6 at one end to rotate in the bearing b7. When the threaded tube 6 rotates, the threaded rod 8 makes a threaded rotational movement with it, causing the threaded rod 8 to change from a rotational movement to a linear movement. At this time, the threaded rod 8 drives the clamping block b9 to approach the clamping block a2, thus achieving the clamping effect, improving the clamping convenience and at the same time improving the stability of the round shaft fixation. When disassembling the round shaft workpiece, rotate the rotating rod 10 in the reverse direction. At the same time, multiple clamping mechanisms can clamp the workpiece, improving the working efficiency and practicality.
