Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Embodiment one

[0032] In order to solve the technical problems in the background art, the following electric actuator shell polishing equipment is given:

[0033] In combination with Figures 1-6 As shown in the figure, the electric actuator shell polishing equipment provided by the present application comprises a workbench 1, the top of the workbench 1 is fixedly provided with a bearing frame 11, two telescopic rods one 12 in vertical shape are symmetrically fixed on the bearing frame 11 and located directly above the workbench 1, mounting blocks 13 are fixedly installed at the bottom of the two telescopic rods one 12, an electric cylinder one 14 connected with the mounting blocks 13 is fixedly installed on the bearing frame 11, a displacement mechanism 2 is installed at the bottom of the mounting block 13, a mounting seat 3 is installed at the end of the displacement mechanism 2, the displacement mechanism 2 is used for horizontally displacing the mounting block 13, a mounting shaft 31 in vertical shape is rotatably installed on the mounting seat 3, a polishing piece 32 is detachably fixedly installed at the bottom of the mounting shaft 31, wherein the detachable installation mode between the polishing piece 32 and the mounting shaft 31 is an existing structure, which belongs to the technical range known to those skilled in the art and will not be described here, and a motor one 33 for driving the mounting shaft 31 to rotate is fixedly installed on the mounting seat 3.

[0034] The top of the workbench 1 is provided with a fixing base 4, a supporting base 41 is connected to the top of the fixing base 4 in a spherical mode, an adjusting mechanism 5 is installed on the fixing base 4 and connected with the supporting base 41, which is used to rotate or stop the rotation of the supporting base 41 around the connection between the supporting base 41 and the fixing base 4, and it is worth noting that when the supporting base 41 is rotated around the connection between the supporting base 41 and the fixing base 4 through the adjusting mechanism 5, the top of the supporting base 41 can be in an inclined state or a horizontal state, the top of the supporting base 41 is provided with a connecting frame 6, a supporting plate 61 is rotatably installed on the connecting frame 6, a motor 62 for driving the supporting plate 61 to rotate is fixedly installed on the connecting frame 6, a vertical column 63 is rotatably installed on the supporting plate 61, a motor 64 for driving the vertical column 63 to rotate is fixedly installed on the supporting plate 61, the top of the vertical column 63 is provided with a positioning mechanism 7, an electric actuator shell is sleeved outside the positioning mechanism 7, and the positioning mechanism 7 is used to position the electric actuator shell sleeved outside the positioning mechanism 7.

[0035] When grinding the electric actuator housing, the electric actuator housing is fitted onto the outside of the positioning mechanism 7. The positioning mechanism 7 positions the electric actuator housing. The electric cylinder 14 moves the mounting block 13 downward along the two telescopic rods 12. With the cooperation of the displacement mechanism 2, the mounting seat 3 moves horizontally, allowing the grinding disc 32 to contact the surface of the electric actuator housing. The motor 33 is activated, driving the mounting shaft 31 to rotate on the mounting seat 3, thereby rotating the grinding disc 32 to achieve the grinding effect on the surface of the electric actuator housing. Since the electric actuator housing is fitted onto the outside of the positioning mechanism 7, no clamping surface is formed between the positioning mechanism 7 and the outer wall of the electric actuator housing. When grinding other surfaces of the outer wall of the electric actuator housing, the adjustment mechanism 5 rotates the support base 41 around its connection with the fixed base 4, causing the top of the support base 41 to be inclined or horizontal, thereby driving the connecting frame 6 to move synchronously. The motor 62 then moves the support base 41 to the horizontal position. The support plate 61 rotates on the connecting frame 6. Through the cooperation of the electric cylinder 14 and the displacement mechanism 2, the other surfaces of the outer wall of the electric actuator housing can be polished. The column 63 is driven to rotate 180 degrees around the support plate 61. When the electric actuator housing is located below the support plate 61, the side of the electric actuator housing near the support plate 61 is located at the top of the electric actuator housing. At this time, through the cooperation of the electric cylinder 14 and the displacement mechanism 2, the polishing disc 32 contacts the side of the electric actuator housing near the support plate 61. The motor 33 is turned on, and the motor 64 causes the column 63 to rotate on the support plate 61, thus polishing the side of the electric actuator housing near the support plate 61. This achieves complete polishing of the outer wall of the electric actuator housing. It eliminates the need for workers to disassemble the electric actuator housing, manually flip and adjust it, and then clamp and position it. This is more convenient, reduces the workload of workers, and improves polishing efficiency.

[0039] In the embodiment, the adjusting mechanism 5 comprises a rotating ring 51 rotatably connected with the fixed seat 4 and arranged outside the supporting seat 41, an outer gear ring 52 is coaxially fixedly connected to the outside of the rotating ring 51, an electric motor four 53 is fixedly installed on the fixed seat 4, an output shaft of the electric motor four 53 is coaxially fixedly connected with a gear 54 engaged with the outer gear ring 52, an electric push rod two 55 is hingedly connected to the top of the rotating ring 51, the other end of the electric push rod two 55 is hingedly connected with the supporting seat 41, during use, the electric motor four 53 is controlled to be turned on, the output shaft of the electric motor four 53 is rotated to drive the gear 54 to rotate, so that the rotating ring 51 can be driven to rotate on the fixed seat 4 through the outer gear ring 52, the supporting seat 41 can be driven to rotate around the connection position with the fixed seat 4 through the electric push rod two 55, the piston rod of the electric push rod two 55 is controlled to slide along the cylinder body to the outside or inside of the cylinder body, the two ends of the electric push rod two 55 are rotated with the rotating ring 51 and the supporting seat 41 respectively, so that the supporting seat 41 can be rotated around the connection position with the fixed seat 4, and the top of the supporting seat 41 can be inclined to facilitate control.

[0040] In this embodiment, the positioning mechanism 7 includes a positioning rod 71, a guide rod 72, a positioning plate 73, a sliding block 74, a hinge rod 75, and an electric actuator 76. A positioning rod 71 is fixedly installed at the end of the column 63. A mounting cavity 71 is formed on the positioning rod 71. A guide rod 72 is symmetrically and movably inserted through the positioning rod 71 on one side of the mounting cavity 711.

In use, when positioning the electric actuator housing, the electric actuator housing is fitted onto the outside of the positioning rod 71 through the cavity. The electric actuator rod 76 is controlled to make the sliding block 74 slide on the positioning rod 71. Both hinge rods 75 rotate around their own hinge points on the sliding block 74. The other ends of the two hinge rods 75 rotate between the two positioning plates 73, respectively. This allows the two positioning plates 73 to slide away from each other along the two guide rods 72, so that both positioning plates 73 abut against the inner sidewall of the cavity of the electric actuator housing. This achieves the positioning effect of the electric actuator housing body, and the operation is simple.

[0041] Example 3

[0042] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0043] In this embodiment, the connecting frame 6 includes a base plate 65 fixedly installed on the top of the support base 41. Vertical telescopic rods 66 are fixedly installed on both sides of the top of the base plate 65. A vertical plate 67 is fixedly installed on the top of the telescopic rods 66. An electric cylinder 68 connected to the vertical plate 67 is fixedly installed on the base plate 65. The support plate 61 is located between the opposite sides of the two vertical plates 67 and is rotatably connected to both vertical plates 67. A motor 62 is fixedly installed on one of the vertical plates 67 and connected to the support plate 61. By setting the connecting frame 6 to include the base plate 65, telescopic rods 66, vertical plates 67 and electric cylinder 68, in use, the two vertical plates 67 are simultaneously slid upward along the telescopic rods 66 by the two electric cylinders 68, which can adjust the height of the support plate 61 and increase the distance between the support plate 61 and the base plate 65. This makes the device suitable for grinding larger electric actuator housings, increasing its applicability.

[0044] In the embodiment, the bottom of the mounting block 13 is fixedly provided with a cover 8 sleeved outside the two connecting plates 21. It is worth noting that the bottom of the cover 8 extends below the polishing sheet 32. The workbench 1 is provided with a negative pressure assembly 9. The cover 8 is connected with a corrugated hose 81. The other end of the corrugated hose 81 is connected with the negative pressure assembly 9. The negative pressure assembly 9 is used to form negative pressure in the corrugated hose 81. By arranging the cover 8, when the electric actuator shell is polished, the cover 8 is sleeved outside the electric actuator shell. At this time, the negative pressure assembly 9 is used to form negative pressure in the corrugated hose 81, so that the air in the cover 8 enters the corrugated hose 81. When the air flows, the smoke and dust generated during the polishing of the electric actuator shell are sucked into the corrugated hose 81, so that the smoke and dust generated during the polishing of the electric actuator shell are absorbed and treated, the smoke generated during the polishing of the electric actuator shell is effectively prevented from being discharged into the environment, the air quality of the environment is reduced, the physical harm to the workers is avoided, and the situation that the workers are accidentally injured by the splashing of the debris is effectively avoided.

[0045] In the embodiment, the negative pressure assembly 9 comprises a negative pressure box 91 fixedly arranged at the bottom of the workbench 1. One side of the negative pressure box 91 is open.

The filter plate 93 is fixedly arranged in the negative pressure box 91 by screws. The negative pressure box 91 is fixedly provided with an air suction fan 94 in the through hole 92. The negative pressure box 91 is hingedly provided with a blocking plate 95 used to block the open end of the negative pressure box 91. By arranging the blocking plate 95, the open end of the negative pressure box 91 is blocked. The blocking plate 95 is hingedly arranged on the negative pressure box 91, so that the open end of the negative pressure box 91 is blocked or unblocked. The blocking plate 95 and the negative pressure box 91 are fixed by buckles, so that the blocking plate 95 and the negative pressure box 91 are fixed. In use, the air suction fan 94 is controlled to be turned on. When the air suction fan 94 works, the air in the negative pressure box 91 is sucked out through the through hole 92, so that negative pressure is formed in the negative pressure box 91. The corrugated hose 81 is in communication with the negative pressure box 91, so that negative pressure is formed in the corrugated hose 81. At this time, when the air flows, the smoke and dust in the corrugated hose 81 flow into the negative pressure box 91. When the air in the negative pressure box 91 flows out through the through hole 92, the filter plate 93 filters the smoke and dust, so that the smoke generated during the polishing of the electric actuator shell is effectively prevented from being discharged into the environment. At the same time, the debris is left in the negative pressure box 91, so that the debris is collected.

[0046] In the embodiment, the negative pressure box 91 is provided with a collecting box 96 with an open top, the top of the collecting box 96 is below the through hole 92, one side of the sealing plate 95 is fixedly provided with a rubber pad 951 which can abut against the negative pressure box 91, by providing the collecting box 96, the debris remaining in the negative pressure box 91 can fall into the collecting box 96 under the action of gravity, the debris is collected by the collecting box 96, by providing the collecting box 96 which is inserted into the negative pressure box 91, the collecting box 96 is convenient to disassemble, so that the debris collected in the collecting box 96 is convenient to process, by providing the rubber pad 951, when the sealing plate 95 seals the open end of the negative pressure box 91, the adhesion between the sealing plate 95 and the negative pressure box 91 is increased, so that the sealing property between the sealing plate 95 and the negative pressure box 91 is increased.
