[0033] The following is in conjunction with the appendix Figure 1-6 The present invention will provide a more detailed description of an embodiment of a clamping device for machining a reducer housing.

[0034] A clamping device for machining a gearbox housing, such as Figure 1 , 2 As shown, the support frame 1 is pre-installed in a predetermined position. The support frame 1 includes a support plate 14, which is rectangular in shape. A fixing frame 15 is vertically installed on the top surface of the support plate 14. The fixing frame 15 is U-shaped. Support columns 16 are vertically installed at the four corners of the bottom surface of the support plate 14. The four support columns 16 are cylindrical in shape and provide support for the support plate 14.

[0035] In this embodiment, such as Figure 3As shown, a placement groove 13 is provided on the top surface of the support plate 14, and a movable plate 8 is slidably connected in the placement groove 13. A third drive assembly 9 is provided on the bottom surface of the support frame 1. The third drive assembly 9 electrically drives the movable plate 8 to move horizontally. The third drive assembly 9 includes two hydraulic cylinders 91, which are symmetrically installed on the inner side of two support columns 16. The piston rods of the two hydraulic cylinders 91 are fixed to the bottom surface of the movable plate 8. When the two hydraulic cylinders 91 are started, the piston rods of the two hydraulic cylinders 91 drive the movable plate 8 to move linearly. The operator places the reducer housing to be processed on the top surface of the movable plate 8 in advance, and then starts the hydraulic cylinders 91. The movable plate 8 drives the reducer housing to move. Two sliding rods 92 are symmetrically installed on the two side walls of the placement groove 13. Each sliding rod 92 is slidably connected to a slider 12 fixed to the movable plate 8. The two sliders 12 drive the movable plate 8 to move along the length direction of the two sliding rods 92. The two sliders 12 guide the linear movement of the movable plate 8.

[0036] In this embodiment, a first limiting block 2 is vertically installed on the top surface of the movable plate 8. The first limiting block 2 is rectangular in shape. The user places the gearbox housing to be processed onto the movable plate 8 in advance. The first limiting block 2 is in contact with one side of the gearbox housing. The first limiting block 2 has the function of limiting the gearbox housing. In order to improve the friction between the first limiting block 2 and the gearbox housing, 3-5 hemispherical protrusions are evenly distributed on the inner side of the first limiting block 2. The protrusions have a diameter of 5-8mm, a height of 2-3mm, and are made of rubber.

[0037] In this embodiment, a sliding plate 3 is slidably connected to the bottom surface of the fixed frame 15 in the horizontal direction. A movable frame 5 is provided on the sliding plate 3, and a limiting component is provided on the movable frame 5. Sliding the movable plate 8 will cause the reducer housing to move. When the limiting component corresponds to the first limiting block 2 in the horizontal direction, the movement stops. The limiting component and the first limiting block 2 clamp the reducer housing. When fixing different reducer housings, the sliding plate 3 is moved in the horizontal direction. The sliding plate 3 drives the movable frame 5 to move horizontally. The movable frame 5 drives the limiting component to move horizontally. Adjusting the horizontal distance between the limiting component and the first limiting block 2 can fix reducer housings of different lengths and improve the versatility of the clamping device.

[0038] In this embodiment, a first driving assembly 4 is provided on the top surface of the fixed frame 15. The first driving assembly 4 drives the sliding plate 3 to move in the vertical direction. The first driving assembly 4 includes a servo motor 41, which is horizontally mounted on the top surface of the fixed frame 15. The output shaft of the servo motor 41 is arranged inward. A fixing block 42 is vertically mounted on the top surface of the fixed frame 15. The fixing block 42 and the servo motor 41 are arranged corresponding to each other along the length direction of the fixed frame. A lead screw 43 is mounted on the output shaft of the servo motor 41 through a coupling. One end of the lead screw 43 is rotatably connected to the inner side of the fixing block 42. A drive guide block 44 is threadedly connected to the lead screw 43.

[0039] A first strip-shaped hole 11 is provided on the top surface of the fixed frame 15 in the horizontal direction. The first strip-shaped hole 11 is provided along the length direction of the fixed frame 15. A slider 12 is slidably connected in the first strip-shaped hole 11. The top and bottom surfaces of the slider 12 extend out of the top and bottom surfaces of the fixed frame 15. The top surface of the slider 12 is fixed to the drive guide block 44, and the bottom surface of the slider 12 is fixed to the sliding plate 3.

[0040] The servo motor 41 is started, and the output shaft of the servo motor 41 drives the lead screw 43 to rotate. The lead screw 43 drives the drive guide block 44 to move linearly, the drive guide block 44 drives the slider 12 to move linearly, and the slider 12 drives the sliding plate 3 to move linearly. This realizes the change of the horizontal position of the sliding plate 3 in an electric manner, thereby realizing the adjustment of the distance between the limit component and the first limit block 2 in an electric manner. The whole process does not require manual adjustment by the staff, reducing the workload of the staff and saving time and effort.

[0041] In this embodiment, reference is made to Figure 5 The movable frame 5 is slidably connected to the sliding plate 3 in the vertical direction. At the same time, a second drive assembly 6 is provided on the sliding plate 3. The second drive assembly 6 drives the movable frame 5 to move horizontally. When it is necessary to transport the reducer housing into the fixed frame 15, the movable frame 5 slides upward. The movable frame 5 drives the limit assembly to move upward, adjusting the vertical position of the limit assembly to facilitate the movement of the reducer housing.

[0042] The second drive assembly 6 includes a first cylinder 61, which is vertically mounted on one side of the sliding plate 3. The piston rod of the first cylinder 61 faces downward, and a moving block 62 is horizontally mounted on the piston rod of the first cylinder 61. A sliding groove is formed on one side of the sliding plate 3 in the vertical direction, and the moving block 62 slides in the sliding groove. The end of the moving block 62 away from the cylinder is fixed to the moving frame 5. When the first cylinder 61 is activated, the piston rod of the first cylinder 61 drives the moving block 62 to move vertically. The moving block 62 drives the moving frame 5 to move vertically, and the moving frame 5 drives the limiting assembly 7 to move vertically, thereby realizing the electric adjustment of the position of the limiting assembly 7.

[0043] In this embodiment, the limiting component 7 includes a second cylinder 71. A through hole 620 is provided on one side of the movable frame 5 in a horizontal direction. The second cylinder 71 is horizontally mounted on the movable frame 5. The piston rod of the second cylinder 71 passes through the through hole 620 and is positioned towards the first limiting block 2. A second limiting block 72 is mounted on the piston rod of the second cylinder. The structure, shape, and size of the second limiting block 72 are the same as those of the first limiting block 2. When the first limiting block 2 moves horizontally to the point where its center corresponds to the center of the second limiting block 72 in the same horizontal direction, the second cylinder 71 is activated. The piston rod of the second cylinder 71 drives the second limiting block 72 to move to one side of the reducer housing. The first limiting block 2 and the second limiting block 72 clamp and fix the reducer housing.

[0044] In this embodiment, reference is made to Figure 6 Two first guide rods 121 are symmetrically installed on the side of the sliding plate 3 away from the first cylinder 61. The moving block 62 is located between the two first guide rods 121. Two elongated holes 52 are symmetrically opened in the vertical direction on the inner side of the moving frame 5. The two first guide rods 121 slide relative to the two elongated holes 52. The two first guide rods 121 have a guiding effect on the vertical movement of the moving frame 5.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
