Description

Technical Field

[0001] The utility model relates to the technical field of motor housing production, in particular to a deburring device for motor housing production. Background Technique

[0002] The motor housing is generally formed by pouring and cooling liquid metal in a mold. Due to reasons such as mold splicing seams and pouring quality, redundant metal parts will be formed on the surface of the motor housing after cooling at the seams or where the mold is not completely aligned on the housing surface, which is called burrs in the industry.

[0003] Burrs will not only form on the outside of the housing, but also a large amount of burrs will be generated inside the motor housing. The burrs in this part are formed at the splicing seams of the mold and are in the shape of flakes.

[0004] Due to the irregular shape of the motor housing surface, high precision is required for mechanical grinding. Generally, it is operated manually. When manually grinding the burrs on the inner wall of the motor housing, it is time-consuming and laborious because the exact position of the burrs cannot be seen.

[0005] Therefore, it is necessary to provide a deburring device for motor housing production to solve the above technical problems. Content of the Utility Model

Detailed Embodiments

[0023] The following further describes the utility model in conjunction with the drawings and embodiments. The implementation manners of the utility model include but are not limited to the following embodiments.

[0024] First Embodiment:

[0025] As Figures 1-4As shown in the figure, the deburring device for the production of the motor housing provided by the present utility model includes: a bottom plate 101, a slide rail 109 is provided at the upper end of the bottom plate 101, a slider 102 is slidably provided on the upper end of the slide rail 109, a base 103 is installed on the slider 102, the base 103 is arc-shaped, the motor housing to be polished can be placed inside the arc of the base 103, and the inner wall of the arc fits with the outer wall of the motor housing. A motor 104 is also installed on the bottom plate 101. As a driving device, the motor 104 is connected to a rotating shaft 105 through a belt. One end of the rotating shaft 105 is installed with a grinding head 107. The grinding head 107 is detachably installed at the end of the rotating shaft 105. The grinding head 107 is composed of a sleeve and steel wires. The diameter of the grinding head 107 is slightly larger than the inner diameter of the motor 104 housing. The rotating shaft 105 is installed and fixed on the bottom plate 101 through a support 106. A bearing is installed at the connection between the rotating shaft 105 and the support 106. In this way, the rotating shaft 105 can rotate on the support 106. An elastic band 108 is provided on the base 103. The elastic band 108 can use rubber as its material, such as a used bicycle inner tube, etc. One end of it is fixed on the side wall of the base 103 through a splint. A groove 112 is provided on the base 103, and the groove 112 runs through. The other end of the elastic band 108 is detachably fixed in the groove 112, for example, it can be tied to the edge of the groove 112. When in use, first place the motor housing on the arc-shaped base 103, then use the elastic band 108 to go around the motor housing and tighten it, and tie the other end to the edge of the groove 112. Under the restraint of the elastic band 108, the motor housing is fixed on the base 103. Then start the motor 104. Driven by the motor 104, the rotating shaft 105 rotates, and then drives the grinding head 107 to rotate. Push the base 103 to drive the motor housing to move towards the direction of the grinding head 107. Since the steel wires of the grinding head 107 have good elasticity and deform under the restraint of the inner wall of the motor housing, the grinding head 107 can be inserted into the motor housing and rotate. During the rotation, the grinding head 107 continuously rubs against the inner wall of the motor housing, and the burrs are cleaned during the friction process, achieving the grinding effect.

[0026] By setting up related devices such as the grinding head 107, the grinding effect on the inner wall of the motor housing is achieved. Compared with the existing manual deburring, the mechanical deburring has higher efficiency and better grinding effect, and can save a large amount of working time.

[0027] Second Embodiment:

[0028] As Figures 1-2 shown, a lead screw 110 is provided on the base 103. One end of the lead screw 110 is movably installed on the support 106, for example, it can be installed through a rotating shaft. The other end of the lead screw 110 is installed with a handwheel 111. This part is a lead screw transmission structure. The user rotates the handwheel 111 to drive the lead screw 110 to rotate. After the lead screw 110 rotates, it pushes the slider 102 threaded with it to move, thereby driving the base 103 to move.

[0029] By setting the lead screw 110, the effect of controlling the front-back movement of the slider 102 is achieved. In addition, the operator only needs to rotate the handwheel 111 to control the movement of the motor housing. There is a certain distance between the grinding part and the operator to prevent the generated debris, dust, etc. from harming the staff.

[0030] Third Embodiment:

[0031] As Figures 3-4 shown, one end of the elastic band 108 is a fixed end, and the other end is a free end. When in use, the free end of the elastic band 108 needs to be fixed to achieve the fixing effect of the elastic band 108 on the motor housing. The connection method between the free end and the base 103 is realized through the following structure: A fixing piece 113 is installed at one end of the elastic band 108, and the length of the fixing piece 113 is greater than the length of the groove 112. When in use, the fixing piece 113 is obliquely placed into the groove 112. After being placed on the other side of the groove 112, the fixing piece 113 is stuck on the back of the groove 112 under the elastic force generated after the elastic band 108 is stretched, thereby realizing the fixation of the free end of the elastic band 108.

[0032] By setting the fixing piece 113, the quick connection and disassembly effect of the free end of the elastic band 108 is achieved, which is convenient for the staff to use.

[0033] Fourth Embodiment:

[0034] As Figure 2 shown, a notch is provided at the lower end of the bottom plate 101, and the notch is located directly below the grinding head 107. Debris will be generated during the grinding process of the motor housing, and the generated debris falls into the prepared storage device below the device through the notch, preventing environmental pollution. At the same time, the collected metal debris can also be recycled.

[0035] Fifth Embodiment:

[0036] A rubber pad is provided on the upper end of the base 103. When in use, the motor housing is constrained between the base 103 and the elastic band 108, and there is a certain pressure on the contact surface. When the motor housing is pushed to make the grinding head 107 enter the interior of the motor housing, the grinding head 107 has a horizontal thrust on the motor housing. At this time, setting a rubber pad on the upper part of the base 103 can increase the friction coefficient between the motor housing and its contact surface to prevent the motor housing from moving.

[0037] In use, first place the motor housing on the arc-shaped base 103, then use the elastic band 108 to bypass the motor housing and tighten it, and tie the other end to the edge of the groove 112. Under the restraint of the elastic band 108, the motor housing is fixed on the base 103. Then start the motor 104. Driven by the motor 104, the rotating shaft 105 rotates, and then drives the grinding head 107 to rotate. Push the base 103 to drive the motor housing to move in the direction of the grinding head 107. Since the steel wire of the grinding head 107 has good elasticity, it deforms under the restraint of the inner wall of the motor housing. Therefore, the grinding head 107 can be inserted into the motor housing and rotate. During the rotation, the grinding head 107 continuously rubs against the inner wall of the motor housing, and the burrs are cleaned during the friction, achieving the grinding effect.

[0038] The above embodiments are only one of the preferred embodiments of the present invention and should not be used to limit the protection scope of the present invention. Any meaningless changes or polish made in the main design concept and spirit of the present invention, as long as the technical problems solved are still the same as those of the present invention, should be included in the protection scope of the present invention.
