Description

Technical Field

[0001] The utility model relates to the field of polishing equipment, in particular to a motor end cover polishing device. Background Art

[0002] The motor end cover is a cover installed at one end of the motor casing. The end cover has a bearing chamber for placing the bearing and a stopper that cooperates with the base. The end cover supports the rotating part, determines the relative position of the rotor and the stator, protects the inside of the motor and guides the wind. Therefore, the quality of the motor end cover directly affects the quality of the motor.

[0003] The current motor end cover polishing device, as described in the patent with announcement number CN209902930U, includes a fixing mechanism, a polishing machine and a vertically arranged vertical plate, on which a horizontally arranged upper mounting plate and a horizontally arranged lower mounting plate are arranged in sequence from top to bottom, the fixing mechanism includes a lifting cylinder installed and fixed on the lower surface of the lower mounting plate, the telescopic end of the lifting cylinder passes through the lower mounting plate, and an end cover fixing tool is installed on the telescopic end of the lifting cylinder, the polishing machine includes a motor installed on the upper part of the vertical plate, a bearing seat is fixedly installed on the upper surface of the upper mounting plate, the middle part of the mounting shaft is rotatably connected to the upper mounting plate through the bearing seat, the lower end of the mounting shaft passes through the upper mounting plate, and the lower end of the mounting shaft is fixed with a polishing disc adapted to the motor end cover.

[0004] With regard to the above-mentioned related technologies, the inventor believes that the motor end cover is detachably mounted on the disc by bolts and a pressure plate to achieve the fixation of the motor end cover, which results in the need to disassemble and assemble the bolts and the pressure plate before and after polishing the motor. This process is time-consuming and labor-intensive, resulting in a relatively low polishing efficiency for the motor end cover. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] See also Figure 1-3 A motor end cap polishing device includes a conveying mechanism 1, the conveying mechanism 1 includes a support table 101, a first motor 103 is fixedly connected to the bottom of the support table 101, and an output end of the first motor 103 is fixedly connected to a rotating table 102 located above the support table 101. The rotating table 102 is used to drive the first motor 103 to rotate when starting work, so that the motor end cap to be polished can be placed on the top of the rotating table 102, so that the motor end cap can be conveyed when the rotating table 102 rotates. A plurality of support columns 109 are fixedly connected to the bottom of the rotating table 102 in an annular array, and a plurality of reinforcing ribs 104 are fixedly connected to the outer side of the support column 109 in an annular array. Each group of reinforcing ribs 104 is fixedly connected to the rotating table 102. The setting of the reinforcing ribs 104 can further connect and fix the support column 109 to the rotating table 102, thereby improving the connection stability between the rotating table 102 and the support column 109.

[0027] The bottom of the support column 109 is movably connected with a ball 110, and the ball 110 is movably connected with the support platform 101. The arrangement of the support column 109 and the ball 110 can play an auxiliary supporting role for the rotating platform 102. The interior of the rotating platform 102 is provided with a plurality of sliding holes 106 in an annular array, and the top of the rotating platform 102 is fixedly connected with a plurality of first limiting columns 105 in an annular array. The interior of each group of sliding holes 106 is penetrated by a second limiting column 107 corresponding to each group of first limiting columns 105. The second limiting columns 107 and the first limiting columns 105 can be inserted into the stopper inside the motor end cover to be polished, so as to play a limiting role for the motor end cover. The bottom of each group of sliding holes 106 is fixedly connected with a moving block 108, and the arrangement of the moving block 108 can drive the second limiting column 107 to move when moving, so as to be tightly pressed against the inner wall of the stopper of the motor end cover of different sizes.

[0028] The clamping mechanism 2 includes a first fixed plate 201 fixedly connected to the bottom of the rotating table 102 in an annular array, and each group of the first fixed plates 201 is slidably connected with a traction rod 204 inside. The setting of the first fixed plate 201 can guide the sliding of the traction rod 204. The traction rod 204 is movably connected to the moving block 108. The end of each group of traction rods 204 away from the cam 210 is fixedly connected with a traction plate 205. The internal thread of the traction plate 205 is connected with an adjusting screw 209. One end of the adjusting screw 209 is fixedly connected to the first fixed plate 201. The setting of the adjusting screw 209 can drive the moving block 108 to move when rotating, so as to adjust the position of the moving block 108 outside the traction rod 204 to meet the requirements of limiting the motor end covers of different sizes.

[0029] A guide rod 203 is symmetrically fixedly connected to one side of each group of first fixed plates 201 away from the cam 210, and a second fixed plate 202 is fixedly connected to one end of the guide rod 203 away from the first fixed plate 201. The second fixed plate 202 is fixedly connected to the rotating table 102. The setting of the guide rod 203 can guide the movement of the moving block 108 and the traction plate 205. A support rod 211 is fixedly connected to the top of the support table 101, and a cam 210 is fixedly connected to the top of the support rod 211. A traction ring 206 is fixedly connected to the outer side of each group of traction rods 204. A return spring 207 is fixedly connected between the traction ring 206 and the first fixed plate 201. Specifically, the return spring 207 is in a compressed state, so that the elastic action of the return spring 207 can push the traction ring 206 and the traction rod 204 to move to one side of the cam 210. Each group of traction rods 204 is movably connected to one end of the cam 210, and each group of movable beads 208 is in contact with the cam 210. The movable beads 208 can roll along the outer side of the cam 210 when the traction rod 204 rotates with the rotating table 102, thereby reducing the wear between the traction rod 204 and the cam 210.

[0030] The polishing mechanism 3 includes a support frame 301 fixedly connected to one side of the top of the support platform 101. A hydraulic rod 302 is fixedly connected inside the support frame 301. A roller frame 303 is fixedly connected to the output end of the hydraulic rod 302. The hydraulic rod 302 can drive the roller frame 303 to move up and down when starting the work. The top of the roller frame 303 is symmetrically fixedly connected with guide columns 306. Both sets of guide columns 306 are slidably connected to the support frame 301. The setting of the guide columns 306 can guide the up and down movement of the roller frame 303. The inside of the roller frame 303 is rotatably connected with a polishing roller 305. A second motor 304 is fixedly connected to one side of the roller frame 303. The output end of the second motor 304 is fixedly connected to the polishing roller 305. The second motor 304 can drive the polishing roller 305 to rotate when starting the work, so that the polishing roller 305 can polish the motor cover passing through the bottom thereof.

[0031] When in use, the motor end cover to be polished is placed on the top of the rotating table 102, and the stop in the motor cover to be polished is located on the outside of the corresponding first limiting column 105 and the second limiting column 107, and then the hydraulic rod 302 is started, so that the hydraulic rod 302 drives the roller frame 303 and the polishing roller 305 to move downward until the polishing roller 305 moves downward to the same height as the top of the motor end cover placed on the top of the rotating table 102, and then the first motor 103 is started, so that the first motor 103 drives the rotating table 102 and each group of first fixed plates 201 to rotate, and the first fixed plate 201 can drive the corresponding traction when rotating. The guide rod 204 rotates accordingly, so that the movable bead 208 can roll along the outer side of the cam 210. When the cam 210 rolls away from the concave part of the cam 210, the cam 210 can push the corresponding traction rod 204 and the corresponding moving block 108 to move to the side away from the cam 210, thereby driving the corresponding second limiting column 107 to move to the side away from the first limiting column 105, so that the first limiting column 105 and the second limiting column 107 can press the inner wall of the stopper of the motor end cover to be polished, thereby fixing the motor end cover to be polished, and the motor end cover can also be transported while the rotating table 102 rotates;

[0032] When the motor end cover is conveyed to the bottom of the polishing roller 305, the second motor 304 can be started, so that the second motor 304 can drive the polishing roller 305 to rotate, so that the polishing roller 305 can be continuously rotated to polish the motor end cover. When the motor end cover after polishing is conveyed to the initial position again, the corresponding movable bead 208 rolls to the concave part of the cam 210 again, and the corresponding return spring 207 restores its deformation, thereby pushing the corresponding traction ring 206, traction rod 204 and moving block 108 to move to one side of the cam 210. Thereby, the corresponding second limiting column 107 is driven to move toward the side of the corresponding first limiting column 105 to release the limiting of the motor end cover after polishing. Then, the polished motor end cover can be removed from the top of the rotating table 102, and during the polishing process of the previous group of motor end covers, the subsequent motor end covers to be polished can be placed on the outer sides of each group of first limiting columns 105 and second limiting columns 107, so there is no need to wait for the previous group of motor end covers to be polished before placing the next group of motor end covers to be polished, thereby effectively improving the polishing efficiency of the motor end covers.

They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
