Description

Technical Field

[0001] This utility model relates to the field of dehydration shaft processing technology, specifically a tooling fixture for dehydration shaft processing. Background Technology

[0002] In the field of dehydration shaft machining, tooling fixtures are important equipment to ensure machining accuracy and efficiency.

[0003] Traditional clamping devices for dehydration shaft processing have significant shortcomings in practical applications: their clamping mechanisms typically employ a fixed structure design. When dealing with different models of dehydration shafts, the lengths of various shafts vary considerably, and the distance between the two clamping mechanisms is mostly fixed and cannot be adjusted. This prevents workers from quickly adjusting the clamping position according to the actual length of the shaft during processing. In such cases, workers need to spend a considerable amount of time adjusting the clamping mechanism to accommodate shafts of different lengths, resulting in prolonged clamping time and severely impacting the working efficiency of the clamping device. Utility Model Content

At the same time, the left cylinder is driven to rotate by the rotation drive assembly, and the right cylinder is clamped and fixed by the clamping and fixing assembly. This structure can not only stably clamp different models of dehydration shafts, but also ensure the rotational accuracy of the dehydration shaft during processing, thereby improving the processing quality and the versatility of tooling fixtures.

A first bidirectional lead screw and a first guide rod are installed between two mounting plates on the top of the turntable. A first motor drives the first bidirectional lead screw to rotate, causing two first moving seats to slide the fixed frame on the first guide rod. This allows for rapid adjustment of the distance between the two cylinders. This design can accommodate dehydration shafts of different lengths. Workers do not need to spend a lot of time adjusting the clamping position, greatly shortening the time of the shaft clamping process and effectively improving the working efficiency of the tooling fixture.

Detailed Implementation

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Example 1

[0025] Please refer to Figures 1 to 5As shown, a tooling fixture for processing dehydration shafts includes a base 1. A turntable 2 is rotatably connected to the top of the base 1 via a rotating shaft. Two mounting plates are fixedly connected to the top of the turntable 2, spaced apart to the left and right. A first bidirectional lead screw 3 is rotatably connected between the two mounting plates. A first motor 4 is fixedly connected to the outer side of the left mounting plate. The output end of the first motor 4 is fixedly connected to one end of the first bidirectional lead screw 3. A first guide rod 5, parallel to the first bidirectional lead screw 3, is fixedly connected between the two mounting plates. Two first movable seats 6 are threaded onto the first bidirectional lead screw 3. The first movable seats 6 are slidably connected to the first guide rod 5. A fixing frame 7 is fixedly connected to the top of each of the two first movable seats 6. A cylinder 8 is rotatably connected inside each of the two fixing frames 7. The opposite ends of the two cylinders 8 are open. A clamping assembly 9 is provided inside the cylinder 8. A rotary drive assembly 10 for driving the left cylinder 8 to rotate is provided outside the left fixing frame 7. A clamping and fixing assembly 11 for clamping and fixing the right cylinder 8 is provided outside the right fixing frame 7.

[0026] Those skilled in the art will understand that the top of the base 1 is rotatably connected to the turntable 2 via a rotating shaft. A first bidirectional lead screw 3 and a first guide rod 5 are installed between the two mounting plates on the top of the turntable 2. The first motor 4 drives the first bidirectional lead screw 3 to rotate, causing the two first movable seats 6 threadedly connected to the first bidirectional lead screw 3 to slide on the first guide rod 5, thereby driving the fixed frame 7 on the top of the first movable seat 6 to move. The cylinder 8 inside the fixed frame 7 moves accordingly, realizing the adjustment of the distance between the two cylinders 8. The left cylinder 8 is driven to rotate by the rotation drive assembly 10, and the right cylinder 8 is abutted and fixed by the abutting and fixing assembly 11. The clamping assembly 9 inside the cylinder 8 is used to clamp the dehydration shaft.

[0027] The distance between the two cylinders 8 can be adjusted according to the different lengths of the dehydration shaft, which facilitates the clamping and processing of the dehydration shaft and improves the applicability of the tooling fixture.

[0028] Example 2

[0029] Furthermore, four support legs 12 are evenly distributed at the bottom edge of the base 1, and mounting feet 13 are fixedly connected to the bottom end of the support legs 12. Mounting feet 13 are provided with mounting holes 14.

[0030] Those skilled in the art will understand that the four support legs 12 evenly distributed on the bottom edge of the base 1 are fixed to the workbench through the mounting holes 14 on the mounting feet 13, supporting the entire tooling fixture.

[0031] This ensures that the tooling fixtures are stably mounted on the worktable, guaranteeing stability during the machining process.

[0032] Example 3

[0033] Furthermore, the bottom end of the rotating shaft extends to the bottom of the base 1 and is fixedly connected to the first gear 15. The bottom of the base 1 is fixedly connected to the second motor 16, and the output end of the second motor 16 is fixedly connected to the second gear 17 that meshes with the first gear 15.

[0034] Those skilled in the art will understand that the first gear 15 at the bottom of the shaft meshes with the second gear 17 at the output end of the second motor 16. When the second motor 16 is working, it drives the second gear 17 to rotate, which in turn drives the shaft to rotate through the first gear 15, thereby realizing the rotation of the turntable 2.

[0035] The turntable 2 can drive the cylinder 8 to rotate, which makes it easier to adjust the processing position of the dehydration shaft and improves the processing flexibility.

[0036] Example 4

[0037] Furthermore, a limiting reinforcement block 18 is fixedly connected to the top center of the base 1, and the first guide rod 5 is fixedly connected to the limiting reinforcement block 18. A through hole is provided on the limiting reinforcement block 18 for the first bidirectional lead screw 3 to pass through.

[0038] Those skilled in the art will understand that when the first motor 4 drives the first bidirectional lead screw 3 to rotate, the first movable seat 6 slides on the first guide rod 5, and the limiting reinforcing block 18 provides support for the middle part of the first guide rod 5 through its fixed connection with the first guide rod 5; at the same time, the movement stroke of the first movable seat 6 is limited by the physical obstruction of the limiting reinforcing block 18.

[0039] On the one hand, the limiting reinforcement block 18 enhances the structural strength of the first guide rod 5, preventing it from bending and deforming due to stress during long-term use, and ensuring the guiding accuracy of the first moving seat 6 when sliding; on the other hand, by limiting the movement of the first moving seat 6, it prevents the two cylinders 8 from colliding due to excessive movement or exceeding the reasonable processing range, thereby ensuring the safety and reliability of the tooling fixture when adjusting the spacing.

[0040] Example 5

[0041] Furthermore, the clamping assembly 9 includes several mounting slots 901 formed in a ring array on the inner wall of the cylinder 8. Each mounting slot 901 is rotatably connected to a second bidirectional lead screw 902. A drive unit 903 is provided at the end of the cylinder 8 away from the other cylinder 8 to drive each second bidirectional lead screw 902 to rotate synchronously. Two second movable seats 904 are threadedly connected to the second bidirectional lead screw 902. A push rod 905 is hinged to the side of the two second movable seats 904 near the axis of the cylinder 8. The other ends of the two push rods 905 are hinged to a clamping plate 906. An anti-slip pad 907 is provided on the side of the clamping plate 906 near the axis of the cylinder 8. A second guide rod 908 parallel to the second bidirectional lead screw 902 is fixedly connected in the mounting slot 901. The second movable seats 904 are slidably connected to the second guide rod 908.

[0042] Those skilled in the art will understand that the drive unit 903 drives the second bidirectional lead screw 902 to rotate, the two second moving seats 904 on the second bidirectional lead screw 902 slide on the second guide rod 908, and push the clamping plate 906 to move radially along the cylinder 8 through the hinged push rod 905, and the anti-slip pad 907 on the clamping plate 906 clamps the dehydration shaft.

[0043] It can clamp dehydration shafts of different diameters. The anti-slip pad 907 increases friction to prevent the dehydration shaft from sliding during processing and ensures processing accuracy.

[0044] Example 6

[0045] Furthermore, the drive unit 903 includes a fourth gear 9032 rotatably connected to the center of the end of the cylinder 8 away from its opening end, a second bidirectional lead screw 902 extending to the outside of the cylinder 8 and fixedly connected to a third gear 9031 meshing with the fourth gear 9032, a worm gear 9033 coaxially connected to the outside of the fourth gear 9032, two spaced plates fixedly connected to the outer end of the cylinder 8, a worm 9034 rotatably connected between the two plates, a third motor 9035 fixedly connected to the outside of one of the plates, and the output end of the third motor 9035 fixedly connected to one end of the worm 9034.

[0046] Those skilled in the art will understand that the third motor 9035 drives the worm 9034 to rotate, the worm 9034 meshes with the worm wheel 9033, which in turn drives the worm wheel 9033 and the coaxial fourth gear 9032 to rotate. The fourth gear 9032 meshes with the third gear 9031, thereby driving the second bidirectional lead screw 902 to rotate synchronously.

[0047] The synchronous rotation of each second bidirectional lead screw 902 is achieved, ensuring that multiple clamping plates 906 clamp the dehydration shaft evenly and improving the stability of clamping.

[0048] Example 7

[0049] Furthermore, the rotary drive assembly 10 includes an external gear ring 1001 fixedly connected to the outside of the left cylinder 8, a fourth motor 1002 fixedly connected to the outside of the left fixed frame 7, and a fifth gear 1003 that meshes with the external gear ring 1001 fixedly connected to the output end of the fourth motor 1002.

[0050] Those skilled in the art will understand that the fifth gear 1003 at the output end of the fourth motor 1002 meshes with the external gear ring 1001 outside the left cylinder 8. When the fourth motor 1002 is working, it drives the fifth gear 1003 to rotate, thereby driving the left cylinder 8 to rotate.

[0051] The left cylinder 8 drives the dehydration shaft to rotate, meeting the requirements for the rotation of the dehydration shaft during processing and improving the versatility of processing.

[0052] Example 8

[0053] Furthermore, the clamping and fixing assembly 11 includes a fixing plate 1101 fixedly connected to the outside of the right-side fixing frame 7. A vertically arranged threaded rod 1102 is threadedly connected to the fixing plate 1101. An arc-shaped clamping plate 1103 adapted to the cylinder 8 is rotatably connected to the bottom end of the threaded rod 1102. A flexible pad is provided on the contact surface of the arc-shaped clamping plate 1103. A third guide rod 1104 parallel to the threaded rod 1102 is fixedly connected to the top of the arc-shaped clamping plate 1103. The third guide rod 1104 is slidably connected to the fixing plate 1101. A knob 1105 is fixedly connected to the top end of the threaded rod 1102. A number of anti-slip protrusions 1106 arranged in a ring array to cooperate with the flexible pad are provided on the surface of the cylinder 8.

[0054] Those skilled in the art will understand that rotating the knob 1105 causes the threaded rod 1102 to rotate, and the arc-shaped abutment plate 1103 at the bottom of the threaded rod 1102 moves up and down under the guidance of the third guide rod 1104, pressing against or releasing the right side cylinder 8. The flexible pad on the arc-shaped abutment plate 1103 cooperates with the anti-slip protrusion 1106 on the surface of the cylinder 8 to achieve the pressing and fixing of the right side cylinder 8.

[0055] The right-side cylinder 8 can be fixed to ensure the stability of the dehydration shaft during processing and prevent the rotation of the cylinder 8 from affecting the processing accuracy.

[0056] In this embodiment, the first motor 4, the second motor 16, the third motor 9035, and the fourth motor 1002 used in this application are all existing technologies, and the connections between the components are also existing technologies. Therefore, their connection relationships and principles will not be described in detail here. In addition, in this embodiment, each gear transmission component and the lead screw transmission component is provided with protective measures to ensure that they operate normally and are not affected by external factors. For example, the gear transmission component is provided with a protective cover, and the lead screw transmission component is provided with a bellows protective sleeve.

[0057] The working principle and usage procedure of this device are as follows: First, fix the base 1 to the workbench using the mounting holes 14 on the mounting feet 13. Use the support legs 12 to ensure the stability of the tooling fixture. Based on the length of the dehydration shaft, start the first motor 4 to drive the first bidirectional lead screw 3 to rotate, causing the first movable seat 6 to slide on the first guide rod 5, thus moving the fixing frame 7 and the cylinder 8. Adjust the distance between the two cylinders 8. The limiting reinforcing block 18 supports the first guide rod 5 and limits the stroke of the first movable seat 6. Place the dehydration shaft into the cylinder 8. Start the third motor 9035, which drives the second bidirectional lead screw 9034 through the worm gear 9034, worm wheel 9033, fourth gear 9032, and third gear 9031. 2. Rotate to make the second moving seat 904 slide on the second guide rod 908. Drive the clamping plate 906 to clamp the dehydration shaft with the anti-slip pad 907 through the push rod 905. Then rotate the knob 1105 to make the threaded rod 1102 drive the arc-shaped pressing plate 1103 to press against the right cylinder 8 under the guidance of the third guide rod 1104. The flexible pad and the anti-slip protrusion 1106 cooperate to fix it. During processing, start the fourth motor 1002, which drives the left cylinder 8 to rotate through the fifth gear 1003 and the external gear ring 1001. At the same time, the second motor 16 can be started, which drives the turntable 2 to rotate through the second gear 17 and the first gear 15 to adjust the processing position of the dehydration shaft and complete the processing operation of the dehydration shaft.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
