Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology for galvanized composite conical parts, specifically a clamping device for machining the inner surface of galvanized composite conical parts. Background Technology
[0002] A galvanized composite tapered part is a tapered structural part made of galvanized metal as a base and combined with other materials. The machining of its inner surface plays a decisive role in the part's accuracy, surface quality and performance. Stable clamping of the workpiece during the machining process is the core prerequisite for ensuring machining accuracy.
[0003] A clamping device for machining the inner surface of a thin-walled composite conical part, disclosed in CN217750431U, can effectively drive the clamping plate to move laterally and clamp the conical part by operating an electric telescopic rod. The connecting plate connected to the inner side of the rotating shaft can be rotated by the operation of a motor, which can effectively flip the composite conical part clamped by the clamping plate.
[0004] The clamping device for machining the inner surface of the thin-walled composite conical part uses an internal clamping plate to hold the conical part. However, the clamping plate is rectangular, while the outer surface of the conical part is arc-shaped. When the rectangular clamping plate holds the arc-shaped conical part, the conical part is easily displaced by the compression, which affects the final machining effect. Therefore, it needs to be improved. Utility Model Content

[0027] This utility model provides the following technical solution:
[0028] Example 1
[0029] Please see Figure 1-6 This utility model provides a technical solution: a clamping device for machining the inner surface of a galvanized composite conical part, including a machining table 1, a PLC controller 2 fixedly connected to the right side of the machining table 1, an adjustment mechanism 3 provided at the bottom of the machining table 1, a clamping mechanism 5 provided inside the adjustment mechanism 3, and a conical part body 4 provided at the top of the clamping mechanism 5.
[0030] The adjustment mechanism 3 includes a connecting frame 34, which is fixedly connected to the bottom of the processing table 1. The bottom of the connecting frame 34 is fixedly connected to a self-locking motor 32. The top of the self-locking motor 32 is fixedly connected to a rotating shaft 301. The top of the rotating shaft 301 is rotatably connected to the middle of the bottom of the processing table 1. A gear 31 is fixedly connected to the outer periphery of the rotating shaft 301. A rack 35 meshes with the left and right sides of the gear 31. A T-block 33 is fixedly connected to the top of the rack 35. A fixing plate 38 is fixedly connected to the outer side of the rack 35.

[0031] Furthermore, a T-slot corresponding to the movement trajectory of the T-block 33 is provided on the inner side of the processing table 1, and the T-block 33 is slidably connected inside the T-slot. Through the T-slot, the T-block 33 can slide on the inner side of the processing table 1. The T-block 33 can support the rack 35, making the rack 35 more stable during movement.
[0032] Furthermore, a sliding hole corresponding to the movement trajectory of the rack 35 is provided on the inner side of the connecting frame 34, and the rack 35 is slidably connected to the inner side of the sliding hole. Through the sliding hole, the rack 35 can slide inside the connecting frame 34, making the rack 35 more stable during movement.
[0033] Furthermore, a groove corresponding to the movement trajectory of the sliding hole is provided on the inner side of the fixed plate 38, and the sliding hole is slidably connected to the inside of the groove. Through the groove, the sliding hole can slide on the inner side of the fixed plate 38, so that during the lifting process of the lifting platform 51, the sliding hole can be driven to move up and down through the linkage plate 37.
[0034] Example 2
[0035] Please see Figure 1-6 Furthermore, based on Embodiment 1, the clamping mechanism 5 further includes a hydraulic cylinder 56, which is fixedly connected to the top left and right sides of the processing table 1. A lifting platform 51 is fixedly connected to the top of the hydraulic cylinder 56, and the lifting platform 51 is slidably connected to the outside of the slide plate 39. A telescopic rod 55 is fixedly connected to the bottom of the lifting platform 51, and the bottom of the telescopic rod 55 is fixedly connected to the top inside of the processing table 1. A servo motor 54 is fixedly connected to the top outside of the fixed plate 38, and a linkage rod 59 is fixedly connected to the inside of the servo motor 54. A rotating disk 53 is fixedly connected to the inside of the linkage rod 59, and a support member 501 is fixedly connected to the outside of the rotating disk 53. A connecting plate 52 is fixedly connected to the inside of the rotating disk 53, and a rotating plate 58 is rotatably connected to the inside of the connecting plate 52. A V-shaped clamping plate 57 is fixedly connected to the inside of the rotating plate 58. The V-shaped clamping plate 57 is disposed on the outside of the conical body 4, and the inside of the V-shaped clamping plate 57 is in contact with the outside of the conical body 4.
[0036] Furthermore, a circular groove corresponding to the movement trajectory of the support member 501 is provided on the inner side of the fixed plate 38, and the support member 501 is slidably connected to the inside of the circular groove. Through the circular groove, the support member 501 can slide on the inner side of the fixed plate 38, so that the support member 501 can support the rotating disk 53 and make the rotating disk 53 more stable during rotation.
[0037] Furthermore, a fixing hole corresponding to the position of the linkage rod 59 is provided on the inner side of the fixing plate 38, and the linkage rod 59 is rotatably connected to the inner side of the fixing hole. Through the fixing hole, the linkage rod 59 can rotate inside the fixing plate 38, so that when the servo motor 54 is running, it can drive the rotating disk 53 to rotate through the linkage rod 59.
[0038] In actual operation, when this device is used, the conical body 4 is placed at the top center of the lifting platform 51. The self-locking motor 32 is turned on by the PLC controller 2, so that the self-locking motor 32 drives the gear 31 to rotate through the rotating shaft 301. The gear 31 drives the fixed plate 38 and the rotating disk 53 to move through the rack 35. The rotating disk 53 drives the rotating plate 58 and the V-shaped clamping plate 57 to move through the connecting plate 52. The bottom of the V-shaped clamping plate 57 is blocked by the connecting plate 52, so that the V-shaped clamping plate 57 cannot rotate completely downward, so that the V-shaped clamping plate 57 can clamp the conical body 4. When the V-shaped clamping plate 57 contacts the outside of the conical body 4, the V-shaped clamping plate 57 can drive the rotating plate 58 to rotate, so that the rotating plate 58 can be slightly adjusted up and down inside the connecting plate 52, so that the V-shaped clamping plate 57 can fit more tightly with the outer surface of the conical body 4, and the clamping effect of the conical body 4 is better, making the processing of the inner side of the conical body 4 more stable.
[0039] When the conical body 4 needs to be flipped, the PLC controller 2 opens the hydraulic cylinder 56, causing the hydraulic cylinder 56 to move the lifting platform 51 downward, moving the lifting platform 51 away from the bottom of the conical body 4. The PLC controller 2 then opens the servo motor 54, causing the servo motor 54 to drive the rotating disk 53 and the connecting plate 52 to rotate via the linkage rod 59. The connecting plate 52 then drives the V-shaped clamping plate 57 to rotate via the rotating plate 58, causing the V-shaped clamping plate 57 to rotate the conical body 4 180 degrees. After the conical body 4 has rotated, the PLC controller 2 opens the hydraulic cylinder 56, causing the hydraulic cylinder 56 to move the lifting platform 51 upward, so that the top of the lifting platform 51 contacts the bottom of the conical body 4, providing support for the conical body 4 and allowing the inner bottom side of the conical body 4 to be better processed.
