Description

Technical Field

[0001] This application relates to the field of tooling and fixtures, and in particular to a workpiece clamping platform. Background Technology

[0002] In the field of workpiece machining, the flexibility of the clamping device in switching positions directly affects the efficiency of the workpiece machining process.

[0003] Currently, traditional clamping platforms can only clamp workpieces at a single loading or machining station. When station switching is required, the process of switching between the loading and machining stations is cumbersome, making it difficult to perform loading and machining operations in parallel. The process of loading and clamping the workpiece at the loading station and then transferring the loaded and clamped workpiece to the machining station consumes a lot of time, resulting in low overall workpiece processing efficiency. Utility Model Content

[0004] To improve the efficiency of clamping workpieces for processing, this application provides a workpiece clamping platform.

[0005] The workpiece clamping platform provided in this application adopts the following technical solution: A workpiece clamping platform includes a rotating plate, a main rotating shaft, a base, and a turntable fixture. The main rotating shaft is mounted on the rotating plate and is used to drive the rotating plate to rotate. Multiple bases are circumferentially spaced on the rotating plate. The turntable fixture is mounted on the base and is used to position the workpiece.

[0006] By adopting the above technical solution, the main shaft drives the rotating plate to rotate, and the rotating plate drives multiple bases to rotate, so that the turntable fixture on the base can rotate to the workpiece loading station and the processing station respectively. The workpiece can be loaded onto the turntable fixture at the loading station for positioning, and at the same time, the workpiece positioned by the turntable fixture on the base at the processing station can be processed. This reduces the time spent switching between the loading station and the processing station and improves the efficiency of clamping and processing the workpiece.

[0007] Optionally, the base is rotatably mounted on a rotating plate, and the rotating plate is provided with a secondary rotating shaft for driving the base to rotate.

[0008] By adopting the above technical solution, the secondary shaft drives the base to rotate, which in turn drives the turntable fixture to rotate, adjusting the angle of the turntable fixture. This facilitates the precise loading of the workpiece onto the turntable fixture for positioning. Simultaneously, during the processing, the turntable fixture can also adjust the angle of the workpiece, which is beneficial for processing the workpiece at different angles, thus improving the accuracy and convenience of workpiece clamping and processing.

[0009] Optionally, the turntable fixture includes a positioning disk, positioning blocks, and positioning components. The positioning disk is mounted on a base. Multiple positioning blocks are slidably arranged circumferentially on the positioning disk. The positioning components are mounted on the positioning disk and are used to drive the positioning blocks to slide toward the center of the positioning disk.

[0010] By adopting the above technical solution, after the workpiece is loaded onto the positioning plate, the positioning component drives multiple positioning blocks to slide towards the center of the positioning plate. The multiple positioning blocks can then press against different sides of the workpiece, thereby clamping and positioning the workpiece.

[0011] Optionally, the positioning disk has a guide groove with an opening width smaller than the internal opening width, and the positioning block is slidably disposed in the guide groove.

[0012] By adopting the above technical solution, the guide groove limits the movement of the positioning block, thereby improving the stability of the positioning block on the positioning plate and the stability of the positioning block during movement.

[0013] Optionally, the positioning component includes a positioning motor, positioning screws, and a positioning gear set. The positioning motor is mounted on the positioning disk. Multiple positioning screws are rotatably mounted on the positioning disk, and the multiple positioning screws are threadedly connected to multiple positioning blocks respectively. The positioning gear set is mounted on the positioning disk and is used to drive the multiple positioning screws to rotate when the output shaft of the positioning motor rotates.

[0014] By adopting the above technical solution, the positioning motor is started, and the output shaft of the positioning motor drives multiple positioning screws to rotate through the positioning gear set. The multiple positioning screws can then drive multiple positioning blocks to move synchronously, thus conveniently and synchronously controlling the sliding of multiple positioning blocks.

[0015] Optionally, an adjustment seat is slidably disposed on the base, the positioning plate is disposed on the adjustment seat, and an adjustment component for driving the adjustment seat to slide is disposed on the base.

[0016] By adopting the above technical solution, the adjusting component drives the adjusting seat to slide on the base, which in turn drives the positioning plate to move on the base, thereby adjusting the position of the positioning plate on the base and improving the applicability of the positioning plate to the needs of positioning workpieces in different positions.

[0017] Optionally, the adjusting component includes an adjusting screw, which is rotatably mounted on the base and threaded onto the adjusting seat.

[0018] By adopting the above technical solution, turning the adjusting screw can easily drive the adjusting seat to slide.

[0019] Optionally, the positioning disk is rotatably mounted on an adjusting seat, and the adjusting seat is provided with an adjusting shaft for driving the positioning disk to rotate.

[0020] By adopting the above technical solution, the positioning disk can be rotated by adjusting the shaft drive, and the positioning disk can drive the workpiece to rotate, thereby improving the convenience of processing different sides of the workpiece.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Load the workpiece from the loading station onto the turntable fixture for positioning, and simultaneously process the workpiece positioned on the turntable fixture on the base of the processing station. This reduces the time spent switching between the loading station and the processing station and improves the efficiency of clamping and processing the workpiece. 2. The output shaft of the positioning motor drives multiple positioning screws to rotate through the positioning gear set. The multiple positioning screws can then drive multiple positioning blocks to move synchronously, allowing for convenient and synchronous control of the sliding of multiple positioning blocks. 3. Adjust the shaft drive to rotate the positioning plate, which in turn drives the workpiece to rotate, improving the convenience of processing different sides of the workpiece.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] Example 1: This application discloses a workpiece clamping platform.

[0028] Reference Figure 1 The workpiece clamping platform includes a rotating plate 1, a main rotating shaft 2, a base 3, a rotating table fixture 4, and a secondary rotating shaft 5.

[0029] Reference Figure 1 The main rotating shaft 2 is mounted on the rotating plate 1 and is used to drive the rotating plate 1 to rotate. In this embodiment, the main rotating shaft 2 is a servo motor coaxially connected to the rotating shaft of the rotating plate 1. Multiple bases 3 are rotatably mounted on the rotating plate 1, and the multiple bases 3 are distributed circumferentially along the axis of the turntable on the rotating plate 1. The secondary rotating shaft 5 is mounted on the rotating plate 1 and is used to drive the bases 3 to rotate. In this embodiment, the secondary rotating shaft 5 is a servo motor coaxially connected to the rotating shaft of the base 3. Two bases 3 are rotatably mounted on the rotating plate 1. In other embodiments, if the workpiece has multiple processing steps, the remaining number of bases 3 can also be rotatably mounted on the rotating plate 1.

[0030] Reference Figure 1 , Figure 2 Two turntable fixtures 4 are installed at intervals along the length of a base 3. The turntable fixtures 4 are used to position workpieces. The turntable fixtures 4 include a positioning disk 41, a positioning block 42, and a positioning element 43. The positioning disk 41 is installed on the base 3. Multiple guide grooves 6 are spaced apart on the positioning disk 41 in a circular circumferential direction. The opening width of the guide groove 6 is smaller than the inner opening width. In this embodiment, the guide groove 6 is a T-shaped groove. In other embodiments, the guide groove 6 can also be a dovetail groove. One positioning block 42 is slidably installed in one guide groove 6. The positioning element 43 is installed on the positioning disk 41. The positioning element 43 is used to drive the positioning block 42 to slide toward the center of the positioning disk 41. The positioning element 43 includes a positioning motor 431 and a positioning screw 4. The positioning motor 431 is mounted on the axis of the positioning disk 41. Multiple positioning screws 432 are rotatably mounted on the positioning disk 41 at circumferential intervals around the center of the positioning disk 41. The multiple positioning screws 432 are threadedly connected to multiple positioning blocks 42 respectively. The positioning gear set 433 is mounted on the positioning disk 41. The positioning gear set 433 is used to drive the multiple positioning screws 432 to rotate when the output shaft of the positioning motor 431 rotates. In this embodiment, the positioning gear set 433 includes a driving bevel gear and a driven bevel gear. The driving bevel gear is coaxially mounted on the output shaft of the positioning motor 431. One driven bevel gear is coaxially mounted on each positioning screw 432. The multiple driven gears are all meshed on the driving bevel gear.

[0031] After the workpiece is loaded onto the positioning disk 41, the positioning motor 431 is started. The positioning motor 431 drives multiple positioning screws 432 to rotate through the positioning gear set 433. The multiple positioning screws 432 can then drive multiple positioning blocks 42 to move towards the center of the positioning disk 41. The side wall of the guide groove 6 limits the movement of the positioning blocks 42, improving the stability of the positioning blocks 42 on the positioning disk 41 and the stability of the positioning blocks 42 during movement. The multiple positioning blocks 42 are pressed against different sides of the workpiece, which can conveniently clamp and position the workpiece. Moreover, the multiple positioning blocks 42 are all synchronously controlled by the positioning motor 431, improving the efficiency and synchronicity of driving the multiple positioning blocks 42 to move.

[0032] The implementation principle of Embodiment 1 of this application is as follows: After the rotating plate 1 is rotatably installed on the equipment, the main shaft drives the rotating plate 1 to rotate, and the rotating plate 1 drives the two bases 3 to rotate, so that the two bases 3 can be rotated to the workpiece loading station and the processing station respectively. At this time, the workpiece can be loaded onto the turntable fixture 4 on the base 3 for positioning at the loading station. At the same time, the processing station processes the workpiece positioned on the turntable fixture 4 on the other base 3, so that the workpiece loading and processing are carried out simultaneously, reducing the time spent switching between the workpiece loading station and the processing station, and improving the efficiency of clamping the workpiece for processing. In addition, during the workpiece loading and processing, the secondary rotating shaft 5 can also drive the base 3 to rotate, and the base 3 drives the turntable fixture 4 to rotate, adjusting the angle of the turntable fixture 4 and the angle of the workpiece positioned on the turntable. This facilitates the accurate loading of the workpiece onto the turntable fixture 4 for positioning, and at the same time, it drives the workpiece to adjust its angle during processing, which is conducive to processing the workpiece at different angles, improving the accuracy and convenience of workpiece clamping and processing.

[0033] Example 2, refer to Figure 3 The difference between this embodiment and Embodiment 1 is that: an adjustment seat 7 is slidably mounted on the base 3 along the length of the base 3, the positioning disk 41 is rotatably mounted on the adjustment seat 7, and an adjustment shaft 9 is mounted on the adjustment seat 7. The adjustment shaft 9 is used to drive the positioning disk 41 to rotate. In this embodiment, the adjustment shaft 9 is a servo motor coaxially connected to the rotating shaft of the positioning disk 41; an adjustment component 8 is mounted on the base 3. The adjustment component 8 is used to drive the adjustment seat 7 to slide. The adjustment component 8 includes an adjustment screw 81, which is rotatably mounted on the base 3 and threaded through the adjustment seat 7.

[0034] The implementation principle of Embodiment 2 of this application is as follows: When the operator turns the adjusting screw 81, the adjusting screw 81 can drive the adjusting seat 7 to slide, and the adjusting seat 7 can drive the positioning plate 41 to move, thereby adjusting the position of the positioning plate 41 on the base 3, improving the applicability of the positioning plate 41 to the needs of positioning workpieces in different positions. In addition, during the process of loading or processing workpieces, the positioning plate 41 can also be driven to rotate by the adjusting shaft 9, which facilitates better loading of workpieces, or the positioning plate 41 can drive the workpiece to rotate and adjust, which facilitates processing of different sides of the workpiece.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
