Description

Technical Field

[0001] This utility model relates to the technical field of transmission belt fasteners, specifically to an adjustable sliding locking and fixing structure for a synchronous belt pressure plate. Background Technology

[0002] Synchronous belt clamps are used to connect the two ends of open synchronous belts and fix them to the workpiece on the machine to achieve the purpose of transmission. After the synchronous belt and the clamp are combined, the operator secures them by tightening screws and nuts. Some also have threaded holes drilled in the workpiece, allowing screws to be directly tightened into the threads of the workpiece for fixation.

[0003] Current synchronous belt pressure plates all use circular holes, requiring strict adherence to the dimensions of the mounting holes on the workpiece. Before installation, the holes on the workpiece must be precisely positioned. If the workpiece's holes deviate, assembly with the synchronous belt pressure plate is impossible. Since most tooling cannot be reworked or repaired, when hole deviations occur, the workpiece is generally scrapped and the tooling is remade. Furthermore, the strict hole requirements increase the tooling defect rate. Because of defects, the workpiece needs to be remade, requiring a second investment of time, labor, and materials, ultimately increasing the company's production costs and reducing its competitiveness in the industry.

[0004] In summary, it is necessary to invent an adjustable sliding locking and fixing structure for a synchronous belt pressure plate. Utility Model Content

[0005] To address this issue, this invention provides an adjustable sliding locking and fixing structure for a synchronous belt pressure plate, solving the problem that current synchronous belt pressure plates all use circular holes, which impose strict requirements on the dimensions of the workpiece's mounting holes. Before installation, the holes of the workpiece must be precisely positioned; otherwise, assembly with the synchronous belt pressure plate will be impossible.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable sliding locking and fixing structure for a synchronous belt pressure plate, comprising a synchronous open belt, a worktable provided at the bottom of the outer wall of the synchronous open belt, and a fixing component provided at the top of the outer wall of the synchronous open belt for fixing the synchronous open belt to the worktable.

[0007] Preferably, the fixing component is a pressure plate component, which is disposed above the top of the outer wall of the synchronous opening belt. The pressure plate component includes a pressure plate outer frame, and a tooth fixing plate is slidably installed on the front end of the inner wall of the pressure plate outer frame. The bottom end of the outer wall of the tooth fixing plate is provided with fixing tooth grooves, and the inner wall of the fixing tooth grooves meshes with the teeth at the top of the synchronous opening belt.

[0008] Preferably, a limiting toothed rack is fixed to the bottom of the inner wall of the outer frame of the pressure plate on the side near the toothed fixing plate, and a limiting groove is opened at the top of the outer wall of the toothed fixing plate and at the position corresponding to the limiting toothed rack. The outer wall of the limiting toothed rack is slidably connected to the inner wall of the corresponding limiting groove.

[0009] Preferably, side guide blocks are fixed on both sides of the inner wall of the outer frame of the pressure plate, and side guide grooves are provided on both sides of the outer wall of the tooth fixing plate at positions corresponding to the side guide blocks. The outer walls of the side guide blocks are slidably connected to the inner walls of the guide grooves.

[0010] Preferably, the outer frame of the pressure plate and the tooth fixing plate are provided with first waist-shaped holes at the four corners of their outer walls, and the inner walls of the first waist-shaped holes are provided with fixing bolts for fixing.

[0011] Preferably, a second waist-shaped hole is also provided at the top of the outer wall of the synchronous opening belt and at the position corresponding to the first waist-shaped hole, and the end of the fixing bolt passes through the second waist-shaped hole and is fixed to the worktable.

[0012] Preferably, the fixing components are a pressure plate component and a lower auxiliary pressure plate. The lower auxiliary pressure plate is disposed between the synchronous opening belt and the worktable. The pressure plate component is disposed above the top of the outer wall of the synchronous opening belt. The synchronous opening belt, the pressure plate component, and the lower auxiliary pressure plate are all provided with a third oblong hole. The synchronous opening belt, the pressure plate component, and the lower auxiliary pressure plate are fixed with fixing bolts through the third oblong hole.

[0013] The beneficial effects of the utility model are:

[0014] In this utility model, by changing the circular mounting hole of the synchronous belt buckle plate to an oblong mounting hole, the requirements for the size of the mounting hole are reduced, while the efficiency of installation and fixing is improved. Moreover, the oblong fixing hole can achieve a certain range of parallel adjustment, reducing the requirements for hole position and thus reducing the defect rate of fixed workpieces. At the same time, the installation of the oblong hole does not require special hole position, which can further improve the workpiece assembly time, ultimately achieving the effect of increasing efficiency and reducing consumption.

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example 1:

[0024] Refer to the attached Figure 1-5 This utility model provides an adjustable sliding locking and fixing structure for a synchronous belt pressure plate, including a synchronous open belt 100. A worktable 300 is provided at the bottom of the outer wall of the synchronous open belt 100. A fixing component, a pressure plate component 200, is provided at the top of the outer wall of the synchronous open belt 100 to fix the synchronous open belt 100 to the worktable 300. The pressure plate component 200 is positioned above the top of the outer wall of the synchronous open belt 100. By pressing the pressure plate component 200 downwards, it clamps and fixes the synchronous open belt 100 in conjunction with the worktable 300. The pressure plate component 200 includes a pressure plate outer frame 210, and a toothed fixing plate 220 is slidably installed on the front end of the inner wall of the pressure plate outer frame 210. The bottom of the outer wall of the 0 is provided with a fixing groove 221. The inner wall of the fixing groove 221 engages with the teeth at the top of the synchronous opening belt 100. Specifically, by setting the pressure plate outer frame 210 and the tooth fixing plate 220 separately, the teeth of the pressure plate component 200 will be worn after long-term use, and its fixing effect on the synchronous opening belt 100 will be affected. Direct replacement is too costly. However, the cost can be reduced by replacing the tooth fixing plate 220. The tooth fixing plate 220 can be inserted into the pressure plate outer frame 210 during use. The fixing groove 221 at the bottom of the tooth fixing plate 220 can engage with the teeth at the top of the synchronous opening belt 100, thereby fixing the synchronous opening belt 100.

[0025] Limiting racks 230 are fixed to the bottom of the inner wall of the outer frame 210 of the pressure plate, near the tooth fixing plate 220. Limiting grooves are formed at the top of the outer wall of the tooth fixing plate 220, corresponding to the positions of the limiting racks 230. The outer walls of the limiting racks 230 are slidably connected to the inner walls of the corresponding limiting grooves. The limiting racks 230 and the limiting grooves are provided to ensure that the tooth fixing plate 220 does not wobble after being inserted into the outer frame 210 of the pressure plate. A certain amount of friction can be provided between the limiting racks 230 and the limiting grooves to ensure stability. Side guide blocks 231 are fixed to both sides of the inner wall of the outer frame 210 of the pressure plate. Side guide grooves are formed on both sides of the outer wall of the tooth fixing plate 220, corresponding to the positions of the side guide blocks 231. The side guide blocks 231 and the side guide grooves serve a positioning and guiding function. The outer walls of the side guide blocks 231 are slidably connected to the inner walls of the guide grooves. The sliding connection is provided. First oblong holes 211 are provided at the four corners of the outer wall of the pressure plate outer frame 210 and the tooth fixing plate 220. The inner wall of each first oblong hole 211 is provided with a fixing bolt 400 for fixing. A second oblong hole is also provided at the top of the outer wall of the synchronous opening belt 100 and at the position corresponding to the first oblong hole 211. The end of the fixing bolt 400 passes through the second oblong hole and is fixed to the worktable 300. The first oblong holes 211 and the second oblong holes are provided to facilitate the personnel to fix the synchronous opening belt 100, the pressure plate component 200 and the worktable 300 together with the fixing bolt 400. This allows the pressure plate component 200 to cooperate with the worktable 300 to fix the synchronous opening belt 100. By changing the circular mounting hole of the synchronous belt buckle to an oblong mounting hole, the requirements for the size of the mounting hole are reduced, and the efficiency of installation and fixing is improved.

[0026] The usage process of this utility model is as follows: First, the operator can remove the tooth fixing plate 220, align the side guide block 231 with the side guide groove, and align the limiting rack 230 with the limiting groove. Then, the operator uses the equipment to insert the tooth fixing plate 220 into the slot at the front end of the pressure plate outer frame 210, so that the pressure plate outer frame 210 and the tooth fixing plate 220 become a whole. Next, the end of the synchronous opening belt 100 that needs to be fixed is placed on the workbench 300. Then, the fixed pressure plate component 200 is placed on the top of the synchronous opening belt 100, so that the fixing groove 221 engages with the teeth on the synchronous opening belt 100. Then, the fixing bolt 400 is taken out and fixed by passing the fixing bolt 400 through the first waist-shaped hole 211 and the second waist-shaped hole, and then through the pressure plate outer frame 210, the synchronous opening belt 100 and the workbench 300. In this way, the fixing bolt 400 can fix the synchronous opening belt 100 to the pressure plate component 200 and the workbench 300.

[0027] Example 2:

[0028] Refer to the attached Figure 6Compared with Embodiment 1, the difference in this embodiment is that the fixing components are a lower auxiliary pressure plate 500 and an integrated fixing pressure plate 510. Specifically, the integrated fixing pressure plate 510 engages with the top of the synchronous opening belt 100 through a toothed groove at its bottom end, while the lower auxiliary pressure plate 500 can fix the synchronous opening belt 100 from the bottom end in conjunction with the integrated fixing pressure plate 510. The lower auxiliary pressure plate 500 is disposed between the synchronous opening belt 100 and the worktable 300, and the integrated fixing pressure plate 510 is disposed above the top of the outer wall of the synchronous opening belt 100. 0. Both the lower auxiliary pressure plate 500 and the integrated fixed pressure plate 510 are provided with a third oblong hole. The synchronous opening belt 100, the lower auxiliary pressure plate 500 and the integrated fixed pressure plate 510 are fixed to the worktable 300 through the third oblong hole. The third oblong hole is provided to facilitate the fixing bolt 400 to pass through the synchronous opening belt 100, the worktable 300, the lower auxiliary pressure plate 500 and the integrated fixed pressure plate 510 for fixing. By changing the circular mounting hole of the synchronous belt buckle plate to an oblong mounting hole, the requirements for the size of the mounting hole are reduced, and the efficiency of installation and fixing is improved.

[0029] The usage process of this utility model is as follows: First, the operator can place the lower auxiliary pressure plate 500 on the workbench 300. Then, place the end of the synchronous opening belt 100 that needs to be fixed on the lower auxiliary pressure plate 500. Next, take out the integrated fixing pressure plate 510 and place it on the top of the synchronous opening belt 100, so that the tooth groove at the bottom of the integrated fixing pressure plate 510 meshes with the teeth on the synchronous opening belt 100. Then, take out the fixing bolt 400 and fix it by passing it through the third oblong hole, through the synchronous opening belt 100, the workbench 300, the lower auxiliary pressure plate 500, and the integrated fixing pressure plate 510. In this way, the lower auxiliary pressure plate 500 and the integrated fixing pressure plate 510 can clamp and fix the synchronous opening belt 100 through the fixing bolt 400.
