Description

Technical Field

[0001] This utility model relates to the field of machining equipment, specifically to a clamping device for machining the front end cover of an electric motor. Background Technology

[0002] The machining process of the front end cover includes material pretreatment, milling, drilling, tapping, surface treatment, inspection, and assembly. During the drilling process, the front end cover of the motor needs to be clamped and fixed. However, after drilling a hole, the front end cover needs to be rotated to change the drilling position, requiring the end cover to be loosened. This back-and-forth operation makes the drilling process cumbersome and inefficient. Therefore, those skilled in the art have provided a clamping device for machining the front end cover of a motor to solve the problems mentioned in the background art. Utility Model Content

[0027] Please see Figures 1-4 This embodiment provides a clamping device for processing a motor front end cover, including a worktable 1. A fixed ring 6 is fixedly connected to the center of the upper end of the worktable 1. Sliding rods 3 are symmetrically slidably connected to both sides of the fixed ring 6 inside the worktable 1. The sliding rods 3 pass vertically through the worktable 1. A connecting rod 31 is fixedly connected to the upper end of the sliding rod 3. A rotating ring 32 is rotatably connected between the connecting rods 31. The rotating ring 32 is located above the fixed ring 6. An end cover body 5 is provided between the fixed ring 6 and the rotating ring 32. A mounting plate 35 is fixedly connected to the lower end of the sliding rod 3 below the worktable 1. A telescopic rod 4 is fixedly installed below the worktable 1. The lower end of the telescopic rod 4 is connected to the mounting plate 35.

[0028] One end of the connecting rod 31 is fixedly connected to an arc-shaped block 33. The rotating ring 32 has a rotating groove 321 inside. The arc-shaped block 33 is located inside the rotating groove 321. Multiple connecting blocks 322 are fixedly connected below the rotating ring 32. A push rod 323 is rotatably connected to the connecting block 322.

[0029] In use, the end cap body 5 is placed above the fixing ring 6. The telescopic rod 4 extends, and its lower end drives the mounting plate 35 to descend. The mounting plate 35 then drives the connecting rod 31 to descend via the sliding rod 3. The connecting rod 31 drives the rotating ring 32 to descend via the arc-shaped block 33. During the descent of the rotating ring 32, the pushing rod 323 first contacts the upper surface of the end cap body 5. As it descends, the pushing rod 323 tilts and pushes the protrusion of the end cap body 5 towards the center position. When the end cap body 5 reaches the center position, the pushing rod 323 presses the end cap body 5 firmly against the fixing ring 6. The upper surface of the end cap body 5 is then machined using machining equipment. After machining, the rotating ring 32 rotates, causing the end cap body 5 to rotate, thus changing the machining position for further processing.

[0030] In this embodiment, specifically, multiple support legs 2 are fixedly connected below the workbench 1, and the support legs 2 are connected to each other by reinforcing beams.

[0031] In this embodiment, specifically, multiple through holes are provided above the rotating ring 32, and the through holes communicate with the rotating groove 321. The user can easily rotate the rotating ring 32 by inserting a finger into the through hole.

[0032] In this embodiment, the fixing ring 6 is hollow inside, and there is a gap between the lower end of the fixing ring 6 and the upper surface of the worktable 1. During the processing, when debris falls into the fixing ring 6, it can be removed through the gap between the fixing ring 6 and the worktable 1.

[0033] In this embodiment, specifically, a limiting plate 324 is fixedly connected to the lower end of the connecting block 322, and the limiting plate 324 is located outside the push rod 323. The limiting plate 324 prevents the push rod 323 from being directly vertically downward under the action of gravity when it is not in contact with the end cap body 5, but instead keeps it tilted inward. When the lower end of the tilted push rod 323 contacts the upper surface of the end cap body 5, the push rod 323 continues to tilt inward under the gradually decreasing space restriction, thereby pushing the boss of the end cap body 5 to move towards the center position of the rotating ring 32.

[0034] In this embodiment, specifically, a locking bolt 34 is threadedly connected to one end of the arc-shaped block 33, and a rotating handle is connected to one end of the locking bolt 34. The other end of the locking bolt 34 is in close contact with the inside of the rotating ring 32. By rotating the handle, the locking bolt 34 can be rotated. The rotating end of the locking bolt 34 is in close contact with the inside of the rotating ring 32, thereby locking the rotating ring 32. This prevents the rotating ring 32 from rotating with the arc-shaped block 33, and the rotating ring 32 cannot drive the end cap body 5 to rotate. During processing, the end cap body 5 will not move arbitrarily.

[0035] In this embodiment, specifically, the center of the rotating ring 32 and the center of the fixed ring 6 are located on the same vertical line. When the rotating ring 32 drives the end cap body 5 to rotate, the rotation of the end cap body 5 can keep the center of the fixed ring 6 unchanged, so that the position will not shift when the fixed ring 6 supports the end cap body 5.

[0036] In this embodiment, specifically, the push rod 323 is made of an elastic material. When the rotating ring 32 descends and presses the end cap body 5 against the fixed ring 6 via the push rod 323, the push rod 323, being an elastic material, can deform, allowing the rotating ring 32 to continue descending. At this time, the upper section of the rotating ring 32 can approach the upper section of the end cap body 5, reducing the length requirement of the machining tool in the machining equipment.

[0037] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
