[0043] Example 1

[0044] like Figures 1-5 This embodiment provides a grinding device for an elevator motor end cover, including: a mounting base 1; a turntable assembly 2, the turntable body 21 of the turntable assembly 2 being rotatably connected to the mounting base 1; a first protective box 31 connected to the turntable body 21; a clamping assembly 4 connected to the first protective box 31; a second protective box 32 being vertically connected to the mounting base 1 via a gear lifting assembly 6; and a grinding assembly 5 connected to the second protective box 32; wherein the first protective box 31 and the second protective box 32 are clearance-fitted.

[0045] Specifically, during grinding, firstly, the elevator motor end cover 7 is placed inside the first protective box 31 and clamped using the clamping assembly 4; then, the gear lifting assembly 6 is activated, which drives the second protective box 32 to move closer to the first protective box 31 until the first protective box 31 and the second protective box 32 are properly fitted; finally, the grinding assembly 5 is activated, which grinds the elevator motor end cover 7, while simultaneously activating the turntable body 21 of the turntable assembly 2. The turntable body 21 drives the first protective box 31, the clamping assembly 4, and the elevator motor end cover 7 to rotate, so that the grinding assembly 5 performs comprehensive and uniform grinding on the elevator motor end cover 7, ensuring good grinding uniformity.

[0046] The mounting base 1 is used to support the turntable assembly 2, the first protective box 31, the gear lifting assembly 6, and the second protective box 32. The first protective box 31 and the second protective box 32 are designed to prevent the flying of grinding debris and ensure good safety. Since the first protective box 31 and the second protective box 32 are fitted with a clearance, it is easy to prevent the second protective box 32 from interfering with the first protective box 31 as it rotates with the turntable body 21. Since the first protective box 31 is in a circumferential rotating state and the second protective box 32 is in a circumferential stationary state, in order to ensure the anti-splashing performance between the first protective box 31 and the second protective box 32 as much as possible, the shape of both the first protective box 31 and the second protective box 32 is preferably cylindrical.

[0047] Furthermore, such as Figures 3-4 It also includes: a protrusion 311 connected to the first protective box 31; and a groove 321 connected to the second protective box 32, with the groove 321 and the protrusion 311 in clearance fit.

[0048] Specifically, the protrusion 311 and the groove 321 are fitted together with a clearance, which makes the gap 33 between the first protective box 31 and the second protective box 32 present a wavy line shape, thereby further ensuring the anti-waste splashing performance between the first protective box 31 and the second protective box 32.

[0049] Furthermore, such as Figure 1 and Figure 3 The gear lifting assembly 6 includes: a rack 63 connected to the mounting base 1; a support plate 64 that lifts and engages with the rack 63, the support plate 64 being connected to the second protective box 32; a first motor 65 connected to the support plate 64; and a first gear 61 that meshes with the rack 63, one end of the first gear 61 being connected to the output shaft of the first motor 65, and the other end of the first gear 61 being rotatably connected to the support plate 64.

[0050] Specifically, during lifting, the output shaft of the first motor 65 drives the first gear 61 to rotate, and the first gear 61 moves up and down along the rack 63, thereby causing the first motor 65, the support plate 64, and the second protective box 32 to all move up and down along the rack 63.

[0051] Furthermore, such as Figure 1 and Figure 3 It also includes a second gear 62 that meshes with the rack 63, and both ends of the second gear 62 are rotatably connected to the support plate 64.

[0052] Specifically, driven by components such as the first gear 61 and the first motor 65, the second gear 62 also moves up and down along the rack 63. The two gears help to increase the stability of the load-bearing plate 64 and the second protective box 32 as they move up and down along the rack 63.

[0053] Furthermore, such as Figure 1 and Figure 3 The support plate 64 includes a first plate 641 and a second plate 642 that are respectively raised and lowered on both sides of the rack 63. A first motor 65 is connected to the first plate 641, a second protective box 32 is connected to the second plate 642, and the other end of the first gear 61 is rotatably connected to the second plate 642.

[0054] Specifically, the first plate 641 and the second plate 642 help prevent the bearing plate 64 from moving in the horizontal direction and ensure the smoothness of the bearing plate 64 rising and falling along the rack 63.

[0055] Furthermore, such as Figure 2 and Figure 5 The clamping assembly 4 includes: a first clamping head 41 fixedly connected to one side inside the first protective box 31; and a second clamping head 42 threadedly connected to the other side inside the first protective box 31.

[0056] Specifically, the first clamping head 41 and the second clamping head 42 are used to clamp the elevator motor end cover 7. Due to the threaded connection, the distance between the first clamping head 41 and the second clamping head 42 can be adjusted according to the size of the elevator motor end cover 7.

[0057] Furthermore, such as Figure 2 and Figure 5 The second clamping head 42 includes: a clamping head body 421 located inside the first protective box 31; a threaded rod 422 threadedly connected to the other side of the first protective box 31, one end of the threaded rod 422 being rotatably connected to the clamping head body 421; and an internal hexagonal hole 423 provided at the other end of the threaded rod 422.

[0058] Specifically, during adjustment, firstly, the relevant wrench is engaged with the internal hexagonal socket 423. Then, the relevant wrench is rotated, causing the threaded rod 422 to rotate, thereby moving the clamping head body 421 closer to or further away from the first clamping head 41, thus completing the adjustment.

[0059] Furthermore, such as Figure 1 and Figure 3The turntable assembly 2 also includes a second motor connected to the mounting base 1, and the output shaft of the second motor is connected to the turntable body 21.

[0060] Specifically, the output shaft of the second motor is used to drive the turntable body 21 to rotate.

[0061] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
