[0026] This utility model provides, for example Figures 1 to 5 The industrial robot positioning fixture shown includes:
[0027] A processing table 1 is provided with a support frame 22 fixed at the bottom end of the processing table 1. Two movable plates 2 are provided at the top of the processing table 1. Each of the two movable plates 2 has a telescopic plate 3 at its top and a clamping plate 4 on its inner top.
[0028] Two T-shaped insertion slots 5 are respectively opened on the inner top of two telescopic plates 3. A T-shaped insertion block 6 is fixed on the outer side of the clamping plate 4. The two T-shaped insertion blocks 6 are respectively inserted into the two T-shaped insertion slots 5. A movable groove 7 is opened on the inner wall of the T-shaped insertion slot 5. A limiting plate 8 is provided inside the movable groove 7. The rear end of the limiting plate 8 extends to the top of the T-shaped insertion block 6. A first threaded rod 9 is provided inside the movable groove 7. One end of the first threaded rod 9 extends to the front end of the telescopic plate 3 and is rotatably connected to the telescopic plate 3 through a bearing. A first threaded groove 10 is opened at the front end of the limiting plate 8. The other end of the first threaded rod 9 extends into the first threaded groove 10 and is connected to the first threaded groove 10 through a thread. A first throttle 11 is fixed on one end of the first threaded rod 9.
[0029] The top of the movable plate 2 is provided with a telescopic groove 12, and the bottom end of the telescopic plate 3 extends into the telescopic groove 12. The telescopic groove 12 is provided with a second threaded rod 13. The bottom end of the second threaded rod 13 passes through the bottom end of the movable plate 2 and is rotatably connected to the bottom end of the movable plate 2 through a bearing. The bottom end of the telescopic plate 3 is provided with a second threaded groove 14, and the top end of the second threaded rod 13 extends into the second threaded groove 14 and is connected to the second threaded groove 14 through a thread. The bottom end of the second threaded rod 13 is fixedly provided with a second throttle 15.
[0030] The top of the processing table 1 is provided with an adjustment groove 16. Inside the adjustment groove 16 are two adjustment blocks 17. The tops of the two adjustment blocks 17 are fixedly connected to the bottoms of the two movable plates 2 respectively. The bottoms of the two second threaded rods 13 pass through the two adjustment blocks 17 respectively and extend to the bottom of the adjustment blocks 17. The second throttle 15 is located at the bottom of the adjustment blocks 17. Inside the adjustment groove 16 is a bidirectional lead screw 18. The two ends of the bidirectional lead screw 18 pass through the two adjustment blocks 17 respectively and are rotatably connected to the two ends inside the adjustment groove 16 through bearings. The two ends of the bidirectional lead screw 18 are connected to the two adjustment blocks 17 through threads with opposite thread directions. A motor 19 is fixedly provided on one side of the processing table 1. The output shaft of the motor 19 is fixedly connected to one end of the bidirectional lead screw 18. A limiting slide groove 20 is provided on both the front and rear walls inside the adjustment groove 16. A limiting slider 21 is fixedly provided at both the front and rear ends of the adjustment blocks 17. The four limiting sliders 21 are respectively located inside the two limiting slide grooves 20.
[0031] Based on the side shape of the workpiece to be positioned and clamped, the inner side shapes of the two clamping plates 4 correspond to the inner side shape of the workpiece to be positioned and clamped. The T-shaped plug 6 on the outer side of the clamping plate 4 is inserted into the T-shaped plug groove 5. The first handle 11 is rotated, which drives the first threaded rod 9 to rotate. Since the first threaded rod 9 and the first threaded groove 10 are connected by threads, the limiting plate 8 moves backward with the rotation of the first threaded rod 9. The rear end of the limiting plate 8 will move to the top of the T-shaped plug 6. At this time, the limiting plate 8 will limit and fix the T-shaped plug 6. In this way, the clamping plate 4 can be connected to the telescopic plate 3. The second handle 15 is rotated, which drives the second threaded rod 13 to rotate. Since the second threaded rod 13 and the second threaded groove 14 are connected by threads, the telescopic plate 3 moves up and down with the rotation of the second threaded rod 13. The telescopic plate 3 drives the clamping plate 4 to move up and down. In this way, the clamping and positioning height of the clamping plate 4 can be adjusted, and thus adjusted according to the height of the workpiece to be clamped and positioned.
[0032] Place the workpiece to be clamped and positioned at the top center of the machining table 1, start the motor 19, and the output shaft of the motor 19 drives the bidirectional lead screw 18 to rotate. Since the bidirectional lead screw 18 and the two adjusting blocks 17 are connected by threads, the two adjusting blocks 17 move closer to each other as the bidirectional lead screw 18 rotates. The two adjusting blocks 17 drive the two movable plates 2 and the telescopic plates 3 to move closer to each other. The two telescopic plates 3 drive the two clamping plates 4 to clamp and position the workpiece. In this way, the workpiece can be clamped and positioned at the center of the machining table 1.
[0033] This utility model uses a limiting plate 8 to limit and fix the T-shaped plug block 6 and the clamping plate 4, making the replacement process of the clamping plate 4 simple and convenient. By replacing different clamping plates 4 on the inside of the telescopic plate 3, it can be used to clamp and position workpieces with different shapes, which is highly applicable. Moreover, the height of the clamping plate 4 can be adjusted as needed, further improving the applicability of the device. This embodiment specifically solves the problem in the prior art that when industrial robots clamp and position different workpieces, the shapes of the contact surfaces between different workpieces and the clamping parts of the industrial robot are different, while the shape of the clamping parts of the industrial robot is fixed. Thus, it can only clamp and position workpieces with a fixed contact surface shape, which is not very applicable.
[0034] To provide a more detailed explanation of the positioning device disclosed in this invention, please refer to the accompanying drawings. Figure 1-5 As shown. 1. Quick replacement of the clamping plate:
[0035] When it is necessary to change the workpiece to be processed, firstly, select a matching clamping plate 4 according to the side shape of the new workpiece. During operation, insert the T-shaped plug 6 on the outside of the clamping plate 4 into the T-shaped plug groove 5 on the top of the telescopic plate 3. Then, rotate the first handle 11, which drives the first threaded rod 9 to rotate. Due to the threaded connection between the first threaded rod 9 and the first threaded groove 10, the limiting plate 8 moves backward until its rear end tightly abuts against the top of the T-shaped plug 6, thus completing the locking and fixing of the clamping plate 4. This "T-shaped quick change" design is one of the core innovations of this utility model. Operators do not need any professional tools; they can complete the replacement of the clamping plate 4 in a very short time by manually rotating the first handle 11, thereby shortening the changeover and debugging time from several hours to a few minutes, greatly improving the response speed and flexibility of the production line.
[0036] Additionally, when precise adjustment of the clamping height is required:
[0037] Before clamping the workpiece, the second handle 15 located at the bottom of the adjusting block 17 can be rotated. The second handle 15 drives the second threaded rod 13 to rotate within the telescopic groove 12. Since the second threaded rod 13 is threadedly connected to the second threaded groove 14 at the bottom of the telescopic plate 3, the telescopic plate 3 will move up and down smoothly, thereby driving the clamping plate 4 to adjust its height synchronously. By rotating the second handle 15 for precise height adjustment, it is possible to ensure that the clamping force can be stably applied to the most suitable position of the workpiece, effectively avoiding workpiece deformation or unstable positioning caused by improper clamping points, thus ensuring the accuracy and product qualification rate of subsequent robot processing.
[0038] Finally, this device can also automatically center the clamping width. After placing the workpiece to be clamped at the top center of the processing table 1, the motor 19 located on one side of the processing table 1 is started. The output shaft of the motor 19 drives the bidirectional lead screw 18 inside the adjusting groove 16 to rotate. Since the two ends of the bidirectional lead screw 18 have opposite thread directions and are threadedly connected to two adjusting blocks 17 respectively, the two adjusting blocks 17 will synchronously move closer or further away from each other as the lead screw rotates. The adjusting blocks 17 drive the movable plate 2, the telescopic plate 3, and the clamping plate 4 to move synchronously, ultimately clamping and positioning the workpiece. Throughout the process, the limiting sliders 21 before and after the adjusting blocks 17 slide within the limiting grooves 20, playing a stable guiding role. Using the motor 19 to drive the bidirectional lead screw 18 for synchronous clamping not only automates the clamping process, reducing the labor intensity and potential errors of manual operation, but more importantly, its synchronous centering characteristic ensures that the workpiece, regardless of size, is always accurately positioned at the theoretical center of the processing table 1, providing a reliable guarantee for the standardized operation and high-precision machining of industrial robots.
[0039] In summary, this utility model cleverly solves the core problems of poor applicability, difficult adjustment, and low automation of existing positioning fixtures by using a quick-change clamping plate, a precisely adjustable height, and an automatically centered width adjustment mechanism. It provides an efficient, reliable, and cost-effective positioning solution for the flexible production of industrial robots.
