Description

Technical Field

[0001] This utility model relates to the field of washing machine parts grinding technology, specifically a grinding equipment for producing the rear flange of the inner drum of a washing machine. Background Technology

[0002] The reference patent title is: A Stamping Burr Grinding Device (Authorization Announcement No.: CN219882044U, Authorization Announcement Date: 2023.10.24). It includes a grinding gun body with a grinding shaft extending from it. The grinding shaft has a grinding disc at its end. A pressure cylinder assembly is fitted around the grinding disc on the grinding gun body. The pressure cylinder assembly includes a fixed inner cylinder and a movable outer cylinder arranged coaxially. The movable outer cylinder slides axially relative to the fixed inner cylinder. A limiting hole extending axially is provided on the movable outer cylinder. One end of the fixed inner cylinder is connected to the grinding gun body, and the other end has a limiting piece slidably connected within the limiting hole. A first mounting piece is provided near the grinding gun body outside the fixed inner cylinder. A second mounting piece is provided on the movable outer cylinder between the first mounting piece and the limiting piece. An elastic body is provided between the second mounting piece and the first mounting piece. This grinding device features workpiece supportlessness, convenient and quick grinding, complete overall functionality, and strong practicality.

[0003] Based on the above document: The rear flange of the washing machine inner drum (especially the flange with a hexagonal disc structure) is the core load-bearing and connecting component of the washing machine inner drum. The flatness of its edges and surfaces directly affects the assembly accuracy and operational stability of the inner drum. Therefore, during the production process, it is necessary to perform fine grinding on its multiple edges and end faces.

[0004] Currently, the industry mostly uses semi-automatic grinding devices for grinding hexagonal disc flanges. Operators need to manually place the flange on the workbench and fix it using traditional clamping structures (such as bolt tightening, one-way reciprocating claws, etc.). Then, they use hand-held grinding tools to perform the operation. However, traditional clamping structures are difficult to quickly and accurately align with the hexagonal edges or reserved holes. Often, it is necessary to repeatedly adjust the clamping position to ensure a stable fixation. In addition, hexagonal disc flanges need to be ground separately for each of the six corners and adjacent end faces. In existing semi-automatic devices, each time the grinding position is changed, the clamping structure needs to be loosened manually, the flange needs to be rotated to the target angle, and then it needs to be fixed again. The operation process is cumbersome and time-consuming. Therefore, this utility model provides a grinding device for the production of rear flanges for washing machine inner drums.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 This utility model provides a technical solution: A grinding device for producing the rear flange of a washing machine inner drum includes a grinding table 1 and a flange body 2. A handheld grinder 3 is equipped on the left side of the grinding table 1, and a fixing mechanism 4 is provided on the top of the grinding table 1 for fixing the flange body 2. The fixing mechanism 4 includes: The fixing component 41 includes a placement platform 411 rotatably mounted on the top of the grinding table 1. A fixing motor 412 is fixedly connected to the bottom of the inner cavity of the placement platform 411. One end of the output shaft of the fixing motor 412 is fixedly connected to a rotating disk 413 through a coupling. An arc-shaped groove 414 is opened on the surface of the rotating disk 413. The inner surface of the arc-shaped groove 414 drives the fixing block 415 to slide through the transmission component 5. The rotating component 42 is located inside the polishing table 1 and is used to drive the placement table 411 to rotate intermittently by 60°.

[0018] The fixing block 415 has six sets; Fixed motor 412 is a three-phase asynchronous motor; A control panel is installed on the front side of the grinding table 1, which can control the start and stop of the fixed motor 412 and the rotating motor 421. After the flange body 2 is placed on the placement platform 411 by setting the fixing component 41, the fixing motor 412 is started. The fixing motor 412 drives the rotating disk 413 to rotate. The arc groove 414 on the surface of the rotating disk 413 drives the fixing block 415 to slide through the transmission component 5, so that the fixing block 415 fits tightly against the inner wall of the groove 6 on the surface of the flange body 2, realizing the rapid fixing of the flange body 2. The operation is convenient and the fixing effect is good.

[0019] In this embodiment, the surface of the flange body 2 is provided with a slot 6 for easy fixing of the fixing block 415, and the surface of the fixing block 415 is provided with an anti-slip sleeve.

[0020] The anti-slip sleeve is made of nitrile rubber and has a diamond-shaped anti-slip texture on the surface. The slot 6 is provided with 12 sets and is designed in a symmetrical circular shape; In this embodiment, the transmission assembly 5 includes a transmission seat 51, the top of which is fixedly connected to the bottom of the fixing block 415, and a transmission block 52 is fixedly connected to the bottom of the transmission seat 51. The surface of the transmission block 52 is slidably connected to the inner surface of the arc groove 414.

[0021] In this embodiment, a limiting groove 7 is provided on the top of the placement platform 411, and the inner surface of the limiting groove 7 is slidably connected to the outer surface of the transmission seat 51.

[0022] The transmission seat 51 can be guided and slidably limited by the limiting groove 7; In this embodiment, the rotating assembly 42 includes a rotating motor 421 installed at the bottom of the grinding table 1. One end of the output shaft of the rotating motor 421 extends into the inner cavity of the grinding table 1 and is fixedly connected to a rotating disk 422. A sliding groove 423 is provided on the surface of the rotating disk 422. A rotating rod 424 is fixedly connected to the top of the rotating disk 422. The surface of the rotating rod 424 drives the connecting shaft 425 to rotate at the bottom of the inner cavity of the grinding table 1 through the linkage assembly 8. The top end of the connecting shaft 425 is fixedly connected to the bottom of the placement table 411.

[0023] Rotary motor 421 is a three-phase asynchronous motor; The height of the rotating rod 424 is slightly higher than the height of the linkage plate 82; In this embodiment, the linkage assembly 8 includes a linkage disk 81 mounted on the surface of the connecting shaft 425. A linkage plate 82 and multiple sets of linkage blocks 83 are mounted on the top of the linkage disk 81. The surface of the linkage block 83 is slidably connected to the inner surface of the sliding groove 423. The surface of the linkage block 83 is in contact with and slidably connected to the surface of the rotating disk 422. A toggle block 84 is fixedly connected to the top of the linkage plate 82.

[0024] With the rotation component 42 in place, the rotation motor 421 drives the rotating disk 422 to rotate. The rotating disk 422 drives the connecting shaft 425 to rotate through the linkage component 8, which in turn drives the placement table 411 and the flange body 2 to rotate intermittently by 60°. There is no need to manually adjust the position of the flange body 2, which ensures the accuracy of the rotation angle and improves the grinding efficiency and quality.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] In use, the flange body 2 is placed on the placement platform 411, so that the slot 6 on the surface of the flange body 2 fits onto the surface of the corresponding fixing block 415. The fixing motor 412 is started through the control panel. The fixing motor 412 drives the rotating disk 413 to rotate. When the rotating disk 413 rotates, the inner wall of the arc groove 414 presses the transmission block 52, so that the transmission block 52 drives the transmission seat 51 to slide in the limiting groove 7. The transmission seat 51 drives the fixing block 415 to move synchronously. By the fixing block 415 fitting against the inner wall of the slot 6, multiple sets of fixing blocks 415 are used for external support or clamping to complete the fixing of the flange body 2. Afterwards, the staff uses a handheld grinder 3 to grind the surface of the flange body 2. During the grinding process, when it is necessary to adjust the grinding position of the flange body 2, start the rotating motor 421 through the control panel. The rotating motor 421 drives the rotating disk 422 to rotate. When the rotating disk 422 rotates, the surface of the rotating disk 422 is in contact with and slides on the surfaces of the two adjacent linkage blocks 83. When the rotating rod 424 moves the lever 84, it will cause the sliding groove 423 to cooperate with the linkage block 83. The linkage block 83 slides on the inner surface of the sliding groove 423. Through the sliding groove 423, the linkage block 83, linkage disk 81, linkage plate 82, connecting shaft 425, grinding table 1 and fixed flange body 2 are driven to rotate synchronously by 60° and then stop. Turn off the rotating motor 421 and use the handheld grinder 3 to grind.
