Description

Technical Field

[0001] The utility model relates to the field of casting grinding, in particular to a grinding device for motor housing castings. Background Art

[0002] In casting, the surface of the casting often becomes rough and uneven due to the influence of various factors when the liquid metal solidifies in the mold, and subsequent processing is required to meet the use requirements. Therefore, grinding the motor housing is an indispensable part of the motor housing production. Figure 1 As shown, a plurality of heat sinks 81 are circumferentially arranged on the outer side of the motor housing 8, and a plurality of fixing strips 82 are circumferentially arranged on the inner side of the motor housing. The arrangement of the heat sinks 81 and the fixing strips 82 makes manual polishing of the motor housing 8 more complicated, and it is inevitable that areas will be missed during the polishing process, which affects the polishing quality of the motor housing.

[0009] Preferably, a guide groove for matching with the fixing strip is provided on the placement column, and the fixing strip and the guide groove are interference fit.

[0010] Through the above technical solution, the cooperation between the fixing strip and the guide groove reduces the rotation of the motor housing after being affected by the high-pressure water flow, which causes the situation where areas are missed during the grinding process.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0030] The present application embodiment discloses a grinding device for a motor housing casting:

[0031] Reference Figure 2-Figure 5 A grinding device for motor housing castings includes a workbench 1, a water grinding structure 2, a placement column 3 and a rotating structure 4. The rotating structure 4 and the water grinding structure 2 are arranged on the workbench 1. The placement column 3 rotates on the workbench 1. The motor housing 8 is sleeved on the placement column 3. The length direction of the motor housing 8 is arranged parallel to the ground. The rotating structure 4 is used to rotate the placement column 3. The water grinding structure 2 includes a high-pressure spray gun 21, a driving structure 22 and a water tank 23. The water tank 23 is fixed on one side of the workbench 1. The high-pressure spray gun 21 is connected to the water tank 23 through a water pipe 24. The high-pressure spray gun 21 is arranged toward the motor housing 8. The driving structure 22 is used to drive the high-pressure spray gun 21 to move back and forth along the length direction of the motor housing 8.

[0032] The operator places the motor housing 8 on the placement column 3, and the rotating structure 4 drives the placement column 3 to rotate, thereby driving the motor housing 8 to rotate, and then the motor housing 8 is polished by spraying a high-pressure water flow with abrasive toward the motor housing 8 through the high-pressure spray gun 21, and the high-pressure spray gun 21 is moved back and forth along the length direction of the motor housing 8 through the driving structure 22; the rotation of the motor housing 8 and the back and forth movement of the high-pressure spray gun 21 are coordinated to reduce the situation of missing areas during polishing.

[0033] Reference Figure 2-Figure 4 The driving structure 22 includes a fixed frame 221, a lead screw 222 and a power source 223. The lead screw 222 rotates and is connected to the workbench 1. The fixed frame 221 moves along the length direction of the lead screw 222. The fixed frame 221 is threadedly connected to the lead screw 222. The power source 223 is used to drive the lead screw 222 to rotate. The lead screw 222 rotates on the workbench 1 parallel to the length direction of the motor housing 8 clamped on the rotating structure 4. The high-pressure spray gun 21 is fixed on the fixed frame 221. The power source 223 can be a motor. The power source 223 drives the lead screw 222 to rotate, thereby driving the fixed frame 221 to move back and forth on the lead screw 222, and then drives the high-pressure spray gun 21 fixed on the fixed frame 221 to move back and forth.

[0034] Reference Figure 3 and Figure 5The rotating structure 4 includes a ratchet 41 and a driving member 42. The ratchet 41 rotates on the workbench 1. One end of the placement column 3 passes through the workbench 1 and is fixed on the end face of the ratchet 41. The driving member 42 includes a cam 421, a driving rod 422 and a driving motor 423. The cam 421 rotates on the driving motor 423. One end of the driving rod 422 is fixedly connected to the cam 421. The driving rod 422 is used to drive the ratchet 41 to rotate. The driving motor 423 drives the cam 421 to rotate, thereby driving the driving rod 422 to drive the ratchet 41 to rotate. The interval time when the driving rod 422 drives the ratchet 41 to rotate can be controlled by setting the speed of the driving motor 423 and the size of the cam 421, so as to achieve the purpose of cooperating with the high-pressure spray gun 21.

[0035] Reference Figure 3-Figure 4 , a guide groove 31 for matching the fixing strip 82 is provided on the placement column 3, and the fixing strip 82 and the guide groove 31 are interference fit. The cooperation between the fixing strip 82 and the guide groove 31 reduces the rotation of the motor housing 8 after being affected by the high-pressure water flow, which causes the situation of missing areas during the grinding process. At the same time, the interference fit between the fixing strip 82 and the guide groove 31 will not affect the operator's manual movement of the motor housing 8. It also includes a snap ring 5, which is sleeved on the placement column 3 through the guide groove 31, and a fixing groove 32 is also provided on the guide groove 31. The length direction of the fixing groove 32 is perpendicular to the length direction of the guide groove 31, and the snap ring 5 is interference fit with the guide groove 31 or the fixing groove 32. The operator sets the motor housing 8 onto the placement column 3 through the guide groove 31, and abuts the fixing strip 81 against the bottom wall of the guide groove 31; then abuts the snap ring 5 against the side of the motor housing 8 through the guide groove 31, and then rotates the snap ring 5 to snap it into the fixing groove 32. The cooperation between the snap ring 5 and the fixing groove 32 fixes the motor housing 8 on the placement column 3, reducing the displacement of the motor housing 8 after being affected by the high-pressure water flow, so that the area is missed during the grinding process. At the same time, the interference fit between the snap ring 5 and the guide groove 31 or the fixing groove 32 will not affect the operator's manual movement of the snap ring 5.

[0036] Reference Figure 3 The workbench 1 is also provided with a water tank 6, which is located at the lower end of the placement column 3. The water tank 6 is used to collect the water sprayed onto the motor housing 8, so as to avoid unnecessary collection and cleaning work for the operator. At the same time, a wastewater recovery structure should be provided in the water tank 6, which is used to guide the wastewater out and filter it to recover water resources and abrasives. Such structures are too numerous to mention on the market, and no more redundant description is given.

[0037] Reference Figure 2-Figure 3The workbench 1 is also covered with a housing 7, which is fixed to the workbench 1 by bolts, and the water mill structure 2, the placement column 3 and the rotating structure 4 are arranged in the housing 7. A door panel 71 is hinged on one side of the housing 7, and an observation window 72 is fixed on the door panel 71. The setting of the housing 7 prevents water from splashing outside the workbench 1 during operation, which adds unnecessary cleaning work to the operator. The observation window 72 on the door panel 71 is used to facilitate the operator to observe the internal situation during operation.

[0038] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
