Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a fastening device for processing wet brakes. Background Technology

[0002] In the field of modern machinery manufacturing, wet brakes are widely used in engineering machinery, mining machinery, and other fields due to their advantages such as good heat dissipation, smooth braking, and large braking torque. During the processing of wet brakes, the fastening of the workpiece is a key step in ensuring machining accuracy and product quality; the performance of the fastening device directly affects the processing efficiency and the yield rate of the finished product. Currently, most of the fastening devices commonly used in the market for processing wet brakes adopt a single clamping method, such as fixing the workpiece by clamping only from the outside. This method is difficult to meet the diverse fixing needs of wet brake workpieces of different specifications. For some workpieces with complex structures and special inner and outer diameters, it is impossible to achieve precise positioning and stable clamping. Problems such as workpiece displacement and shaking are prone to occur during processing, resulting in decreased processing accuracy and increased scrap rate.

[0003] Meanwhile, existing fastening devices have limitations in angle adjustment. They usually lack flexible angle adjustment functions, or the adjustment process is cumbersome and the positioning is inaccurate, making it difficult to adapt to the processing requirements of multiple processes and multiple angles, which greatly limits the improvement of processing efficiency. In addition, some fastening devices are not compatible with different types of processing equipment and have poor versatility.

[0004] Therefore, how to provide a fastening device for wet brake processing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a fastening device for processing wet brakes. This invention can effectively solve the problems of existing fastening devices being unable to securely fix complex workpieces and having inconvenient angle adjustment by using synchronous clamping and positioning on the inner and outer sides and flexible angle adjustment functions, thereby significantly improving the processing accuracy and efficiency of wet brakes.

[0006] A fastening device for processing a wet brake according to an embodiment of the present invention includes a support and a movable disc. The movable disc is rotatably mounted on the front end of the support via a rotating shaft. Three sets of first and second sliding grooves are equidistantly arranged inside the movable disc. An outer fixing plate is slidably installed in the first sliding groove. An inner positioning seat is slidably installed in the second sliding groove. A rotating rod is rotatably installed in the second sliding groove. A sleeve rod is rotatably installed in the first sliding groove. The top of the sleeve rod passes through the movable disc, and the top of the rotating rod passes through the sleeve rod and extends to the top of the sleeve rod. A first threaded hole is formed through the outer fixing plate. A second threaded hole is formed through the inner positioning seat. A first thread is formed on the outer wall of the sleeve rod, and the sleeve rod passes through the first threaded hole, with the first thread engaging with the inner thread of the first threaded hole. A second thread is formed on the outer wall of the rotating rod, and the rotating rod passes through the second threaded hole, with the second thread engaging with the inner thread of the second threaded hole.

[0007] Furthermore, handwheels are fixedly installed on the top outer walls of both the sleeve rod and the rotating rod, and the handwheels are used to drive the sleeve rod and the rotating rod to rotate.

[0008] Furthermore, a limiting groove is formed around the movable disc, and a groove is formed on the side wall of the support. A limiting block is movably installed in the groove, and the limiting block can be inserted into the limiting groove.

[0009] Furthermore, a guide rod is fixedly installed in the groove, and the guide rod is movably inserted into the limiting block. A spring is sleeved on the guide rod, and the two ends of the spring are fixedly connected to the inner wall of the groove and the outer wall of the limiting block, respectively.

[0010] Furthermore, mounting holes are provided at equal intervals around the rear side of the support.

[0011] Furthermore, the three sets of first and second slide grooves are circumferentially and equidistantly distributed inside the movable disc to ensure the uniformity of the distribution of the outer fixing plate and the inner positioning seat.

[0012] Furthermore, the external fixing plate can slide radially within the first groove through threaded engagement with the sleeve rod, thereby clamping and fixing the outer workpiece.

[0013] Furthermore, the inner positioning seat can slide radially within the second slide groove through a threaded engagement with the rotating rod, thereby providing positioning support for the inner workpiece.

[0014] Furthermore, the rotating rod is installed through the sleeve rod, and the rotating rod and the sleeve rod can rotate relative to each other to achieve independent adjustment of the external fixing plate and the internal positioning seat.

[0015] Furthermore, the number of limiting grooves is matched with the size of the limiting block, and the limiting grooves are evenly distributed along the circumference of the movable disk to ensure the limiting effect when the movable disk rotates to different positions.

[0016] The beneficial effects of this utility model are: 1. In this utility model, the threaded engagement between the outer fixed clamping plate and the sleeve rod, and the threaded engagement between the inner positioning seat and the rotating rod, enable synchronous clamping and positioning of the inner and outer sides of the wet brake workpiece. The outer fixed clamping plate and the inner positioning seat can be independently adjusted according to the workpiece size. The three sets of equidistant clamping plates and positioning seats ensure uniform force distribution, effectively prevent the workpiece from shifting or shaking during processing, and improve processing accuracy and stability.

[0017] 2. In this utility model, the movable disc is rotatably mounted on the front end of the support via a rotating shaft. Together with the limiting groove, limiting block, spring, and guide rod forming a limiting structure, the movable disc can be easily rotated and reliably limited when the processing angle needs to be adjusted. This allows the device to adapt to the angle requirements of different processing steps, improving the versatility and applicability of the device and meeting diverse processing scenarios.

[0024] like Figure 1-5As shown, this utility model discloses a fastening device for processing wet brakes, including a support 1 and a movable disc 2. The movable disc 2 is rotatably mounted on the front end of the support 1 via a rotating shaft. Three sets of first sliding grooves 5 and second sliding grooves 6 are equidistantly arranged inside the movable disc 2. An outer fixing plate 7 is slidably installed in the first sliding groove 5, and an inner positioning seat 8 is slidably installed in the second sliding groove 6. A rotating rod 10 is rotatably installed in the second sliding groove 6, and a sleeve rod 9 is rotatably installed in the first sliding groove 5. The top of the sleeve rod 9 passes through the movable disc 2. The top of the rotating rod 10 passes through the sleeve rod 9 and extends to the top of the sleeve rod 9. A first screw hole 14 is opened through the outer fixing plate 7, and a second screw hole 15 is opened through the inner positioning seat 8. A first thread 11 is opened on the outer wall of the sleeve rod 9. The sleeve rod 9 passes through the first screw hole 14, and the first thread 11 and the inner wall thread of the first screw hole 14 mesh with each other. A second thread 12 is opened on the outer wall of the rotating rod 10. The rotating rod 10 passes through the second screw hole 15, and the second thread 12 and the inner wall thread of the second screw hole 15 mesh with each other.

[0025] Handwheels 13 are fixedly installed on the top outer walls of both the sleeve rod 9 and the rotating rod 10, and are used to drive the sleeve rod 9 and the rotating rod 10 to rotate. Limiting grooves 3 are formed around the movable plate 2, and a groove 16 is formed on the side wall of the support 1. A limiting block 19 is movably installed in the groove 16 and can be inserted into the limiting groove 3. A guide rod 17 is fixedly installed in the groove 16 and is movably inserted into the limiting block 19. A spring 18 is sleeved on the guide rod 17, and both ends of the spring 18 are fixedly connected to the inner wall of the groove 16 and the outer wall of the limiting block 19, respectively. Mounting holes 4 are equidistantly formed around the rear side of the support 1 for fixing the support 1 to the processing equipment. Three sets of first sliding grooves 5 and second sliding grooves 6 are equidistantly distributed in a circle inside the movable plate 2 to ensure the uniformity of the distribution of the outer fixed clamping plate 7 and the inner positioning seat 8.

[0026] In practical use, the device is first fixed to the designated position on the wet brake processing equipment through the mounting hole 4 on the rear side of the support 1. Then, according to the size of the workpiece to be processed, the handwheel 13 at the top of the sleeve rod 9 is rotated. Since the first thread 11 on the outer wall of the sleeve rod 9 is threadedly engaged with the first screw hole 14 of the outer fixed clamping plate 7, the outer fixed clamping plate 7 will slide radially in the first slide groove 5, thereby adjusting the position of the outer fixed clamping plate 7 and achieving clamping and fixing of the outer side of the workpiece. At the same time, the handwheel 13 at the top of the rotating rod 10 is rotated, and the second thread 12 on the outer wall of the rotating rod 10 is threadedly engaged with the second screw hole 15 of the inner positioning seat 8. The inner positioning seat 8 slides radially in the second slide groove 6, providing positioning support for the inner side of the workpiece. Since the rotating rod 10 is set through the sleeve rod 9 and the two can rotate relative to each other, the outer fixed clamping plate 7 and the inner positioning seat 8 can be adjusted independently to meet the clamping and positioning requirements of different workpieces.

[0027] When the angle of the movable disk 2 needs to be adjusted to accommodate different processing positions, pull the limiting block 19 outward to compress the spring 18, causing the limiting block 19 to disengage from the limiting groove 3. At this time, the movable disk 2 can be rotated. After rotating to the appropriate position, release the limiting block 19. Under the elastic force of the spring 18, the limiting block 19 inserts into the corresponding limiting groove 3, thus achieving the limiting and fixing of the movable disk 2. The limiting grooves 3 are evenly distributed along the circumference of the movable disk 2, and their number matches the size of the limiting blocks 19, ensuring that the movable disk 2 can be reliably limited when rotated to different positions.

[0028] The fastening device for wet brake processing of this utility model achieves internal and external clamping and positioning of the workpiece through the threaded engagement of the sleeve rod 9 with the outer fixed clamping plate 7 and the rotating rod 10 with the inner positioning seat 8. It is easy to adjust and the clamping is firm. The movable disc 2 can rotate and cooperate with the limiting structure to adapt to the needs of different processing angles, thereby improving the versatility of the device and the processing efficiency.

[0029] As a preferred example of this application, the clamping surface of the outer fixing plate 7 and the supporting surface of the inner positioning seat 8 are both provided with anti-slip textures to increase the friction between them and the workpiece and prevent the workpiece from shifting during processing.

[0030] As a preferred example of this application, the main components such as the support 1, movable plate 2, sleeve rod 9, and rotating rod 10 are all made of high-strength steel, which has good wear resistance and stability, can withstand large loads during processing, and ensure the long-term reliable use of the device.

[0031] As a preferred example of this application, the surface of the handwheel 13 is provided with an anti-slip rubber sleeve, which makes it easy for the operator to grip and rotate, improving the convenience and comfort of operation.
