Description

Technical Field

[0001] This utility model relates to the field of slewing bearing processing technology, specifically to a clamping device for deep hole processing of slewing bearings. Background Art

[0002] Slewing bearings are large bearings capable of withstanding combined loads, including large axial and radial loads and overturning moments. However, slewing bearings require the use of machining fixtures for positioning during machining.

[0003] In the prior art, patent document CN216067353U discloses a clamping device for machining slewing bearings, comprising a base, a placement assembly mounted on the base, and a clamping assembly mounted on the base for clamping the slewing bearing. The placement assembly includes a mounting boss mounted on the base. The clamping assembly includes a left clamping block, a right clamping block, and a pusher for simultaneously moving the left and right clamping blocks. The left and right clamping blocks are provided with protective grooves that mate with the slewing bearing. The mounting boss enables the placement of the slewing bearing, while the left and right clamping blocks and the protective grooves provide stable clamping. By placing the teeth of the slewing bearing within the protective grooves, the stability and machining quality of the slewing bearing are improved.

[0004] To address the issue that traditional clamping devices typically clamp the slewing bearing by its edge, existing technology employs a method of placing a boss to position the slewing bearing and using a left clamping block, a right clamping block, and a protective groove to achieve stable clamping of the slewing bearing. However, this method still suffers from the problem that the position of the slewing bearing cannot be flexibly adjusted during use, thus reducing the practicality of the clamping device.

DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] Example 1

[0030] like Figure 1-5As shown, this utility model provides a slewing bearing deep hole machining clamping device, comprising a placement frame 1; an adjustment unit 2 disposed on the outer surface of the placement frame 1 for adjustment; and a clamping unit 3 disposed on the outer surface of the adjustment unit 2 for clamping. The adjustment unit 2 includes an adjustment component disposed on the outer surface of the placement frame 1 and a mounting component disposed on the outer surface of the adjustment component. The clamping unit 3 includes a rotating component disposed on the outer surface of the adjustment unit 2 and a clamping component disposed inside the rotating component. The adjustment component includes a drive motor 21, one side of which is detachably connected to the outer surface of the placement frame 1, and the drive end of the drive motor 21 is fixedly connected to a lead screw rotatably connected to the inner wall of the placement frame 1. 22. The inner wall of the placement frame 1 is detachably connected to a limiting slide rod 23. The outer surface of the limiting slide rod 23 is slidably connected to a moving table 24. The inner wall of the moving table 24 is rotatably connected to the outer surface of the lead screw 22. The mounting assembly includes a mounting frame 25. The bottom surface of the mounting frame 25 is fixedly connected to the upper surface of the moving table 24. When using the slewing bearing deep hole machining clamping device, the placement frame 1 is first installed on the machining table. When it is necessary to adjust the position of the clamping unit 3, the drive motor 21 can be started. The drive end of the drive motor 21 drives the lead screw 22 to rotate, which in turn drives the moving table 24 to move horizontally under the limitation of the limiting slide rod 23, thereby adjusting the position of the moving table 24.

[0031] Example 2

[0032] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the rotating assembly includes a second drive motor 31, the upper surface of the second drive motor 31 is detachably connected to the bottom surface of the mounting frame 25, the upper surface of the second drive motor 31 is detachably connected to a placement platform 33, the upper surface of the placement platform 33 is fixedly connected to a positioning ruler 35, the upper surface of the placement platform 33 has a groove 331, the bottom surface of the placement platform 33 has a positioning hole 332, the bottom surface of the mounting frame 25 is detachably connected to a hydraulic cylinder 32, the telescopic end of the hydraulic cylinder 32 is detachably connected to a positioning column, one end of the positioning column is movably engaged with the inner wall of the positioning hole 332, the clamping assembly includes a threaded rod 34, the outer surface of the threaded rod 34 is rotatably connected to the inner wall of the placement platform 33, the outer surface of the threaded rod 34 is threadedly connected to a moving block 36 that is slidably connected to the inner wall of the placement platform 33, and the outer surface of the moving block 36 is fixedly connected to an arc-shaped clamping plate 37.

[0033] The working principle of the deep hole machining clamping device for the slewing bearing will be explained in detail below.

[0034] like Figure 1-5As shown, when using the slewing bearing deep hole machining clamping device, the placement frame 1 is first installed on the machining table. When it is necessary to clamp and fix the slewing bearing, the slewing bearing to be machined is first placed at the center of the placement table 33. Then, the threaded rod 34 is rotated, which drives the moving block 36 to move under the limit of the placement table 33, thereby adjusting the position of the arc-shaped clamping plate 37, and thus clamping and fixing the slewing bearing. After the fixing is completed, the hydraulic cylinder 32 is activated, so that the positioning pin at the telescopic end of the hydraulic cylinder 32 is inserted into the positioning hole 332, thereby locking the angle of the placement table 33, thus preventing the slewing bearing from rotating during the drilling process. When it is necessary to adjust the angle of the placement table 33, firstly, the positioning pin is pulled out of the positioning hole 332, and then the drive motor 21 is started to drive the placement table 33 to rotate, thereby adjusting the angle of the slewing bearing. After the adjustment is completed, the positioning pin is used to lock the placement table 33 again, which makes it convenient to drill the slewing bearing. When it is necessary to adjust the position of the clamping unit 3, the drive motor 21 is started, and the drive end of the drive motor 21 drives the lead screw 22 to rotate, thereby driving the moving table 24 to move horizontally under the limit of the limit slide 23, thereby adjusting the position of the moving table 24.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
