[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, a fixture for producing electric actuator housings comprises a platform 1; legs 11 are fixed at the four corners of the bottom of the platform 1; a plurality of groups of arc plates 12 are fixed to the middle of the platform 1; a bidirectional threaded rod 13 is connected to the middle of the arc plate 12; both ends of the bidirectional threaded rod 13 are threadedly connected to a clamping plate 14; an inclined rod 15 is fixed to both sides of the clamping plate 14; a plurality of groups of slide grooves 16 are provided in the middle of the platform 1; a gear 17 is fixed to the end of the bidirectional threaded rod 13; a rack plate 18 is meshed with the bottom side of the gear 17; a handle 19 is fixed to the end of the rack plate 18; when working, the electric actuator housing to be processed is first placed in the middle of the two groups of clamping plates 14, and then the handle 19 is held and pulled to drive the rack plate 18 to move. Since the rack plate 18 is in meshing with the gear 17, the rack plate 18 moves The rotation of the two-way threaded rod 13 can drive the two sets of clamps 14 to move closer to each other, and the clamps 14 will drive the inclined rod 15 to slide in the middle of the slide groove 16 when they move closer. When the clamps 14 move to a certain position, the electric actuator housing can be clamped. This step can clamp the electric actuator housing through the clamps 14, thereby preventing the electric actuator from being easily affected by mechanical force and causing position deviation during production, thereby causing the housing position to deviate from the predetermined position, thereby reducing processing accuracy, causing losses, and causing waste of raw materials. Through the interaction between the inclined rod 15 and the slide groove 16, the auxiliary clamps 14 can maintain stability during movement, thereby improving the stability of the clamping of the clamps 14.

[0024] like Figure 1 、 Figure 2 、 Figure 3 As shown, one side of the arc plate 12 is connected to multiple groups of driven shafts 2; the driven shafts 2 and the bidirectional threaded rods 13 are both provided with belt grooves 21 in the middle; the belt grooves 21 are both connected to belts 22 in the middle; the ends of the driven shafts 2 are fixedly connected to connecting columns 23; the bottoms of the connecting columns 23 are fixedly connected to arc-shaped brush plates 24; when working, when the bidirectional threaded rods 13 rotate, the belts 22 will be affected by friction and drive the driven shafts 2 to rotate, and the rotation of the driven shafts 2 will drive the connecting columns 23 and the arc-shaped brush plates 24. 4 is rotated, and the bristles at the bottom of the arc-shaped brush plate 24 come into contact with the rack plate 18 when rotating, thereby cleaning the rack plate 18. In this step, the arc-shaped brush plate 24 can clean the rack plate 18, thereby preventing the electric actuator from easily generating certain debris during production and processing, and the debris will be scattered around due to the influence of the mechanical processing force, thereby causing part of the debris to fall onto the surface of the rack plate 18, affecting the meshing state of the rack plate 18 and the gear 17.

[0025] like Figure 1 、 Figure 3 As shown, both sides of the rack plate 18 are fixed with multiple groups of L-shaped guide pillars 31; the bottoms of the L-shaped guide pillars 31 are fixed with U-shaped plates 32; the middle of the U-shaped plate 32 is rotatably connected with a rotating shaft 33; the middle of the rotating shaft 33 is fixed with a groove roller 34; one side of the platform 1 is fixed with multiple groups of guide rails 3; when working, when the rack plate 18 is pushed, the L-shaped guide pillars 31 will drive the U-shaped plate 32 and the groove roller 34 to move with the movement of the rack plate 18. Because the groove roller 34 is in contact with the surface of the platform 1, it will generate friction with the groove roller 34 when moving, and under the influence of friction, it will drive the rotating shaft 33 to the U-shaped plate 32 The middle part rotates, and because the groove of the groove roller 34 is stuck in the guide rail 3, the groove roller 34 will be restricted by the guide rail 3 to roll in a straight line when rotating. This step can support the rack plate 18 through the opening of the L-shaped guide column 31, thereby providing a certain supporting force for the rack plate 18, making the rack plate 18 more stable when moving. Through the mutual cooperation of the groove roller 34 and the guide rail 3, the moving trajectory of the rack plate 18 can be limited, thereby preventing the rack plate 18 from easily deviating to the left and right due to uneven force when moving, thereby affecting its ability to drive the bidirectional threaded rod 13 to rotate.

[0026] like Figure 1 、 Figure 4 As shown, the middle of the splint 14 is fixed with multiple groups of pillars 4; the ends of the pillars 4 are fixed with extrusion plates 41; the middle of the extrusion plate 41 is fixed with multiple groups of hollow sleeves 42; the middle of the hollow sleeves 42 is connected with a tension spring 43; the ends of the tension spring 43 are connected with an extrusion block 44; during operation, when the splints 14 move closer to each other, they will drive the pillars 4, the extrusion plates 41 and the extrusion blocks 44 to move. When the extrusion blocks 44 contact the housing of the electric actuator, they will be subjected to a certain amount of pressure and transmit the pressure to the tension spring 4 3, thereby forcing the tension spring 43 to be compressed until the extrusion block 44 is in close contact with the shell and the moving clamp 14 can be stopped. This step is because the electric actuator shell is mostly irregular, which easily causes the contact area between the clamp 14 and the shell to be limited, thereby reducing the clamping effect on the shell, and then it is easy for the shell to be positionally offset during production and processing. At this time, through the mutual cooperation of the extrusion block 44 and the tension spring 43, it can adapt to various shapes, thereby increasing the clamping area of the shell, thereby reducing the occurrence of such situations.

[0027] like Figure 1As shown, the middle part of the support legs 11 is fixed with a hollow disc 5; the middle part of the hollow disc 5 is fixed with multiple groups of support rods 51; when working, the hollow disc 5 and the support rods 51 cooperate with each other to assist the support legs 11 to maintain stability. This step, through the action of the hollow disc 5 and the support rods 51, can reduce the situation where the support legs 11 are easily offset due to the influence of machining force during the production of the shell.

[0028] like Figure 1 、 Figure 4 As shown, the middle part of the extrusion block 44 is connected to an anti-skid pad 6; during operation, when the extrusion block 44 clamps the shell, the anti-skid pad 6 will contact the shell before the extrusion block 44, thereby increasing the friction between the shell and the extrusion block 44. This step can further increase the clamping effect of the extrusion block 44 through the action of the anti-skid pad 6, thereby making the shell more stable during production and processing.

[0029] like Figure 1 、 Figure 2 As shown, a sponge ring 7 is connected to the middle of the handle 19; during work, when the staff holds the handle 19 and pulls it, the sponge ring 7 can increase the comfort of their hands. This step can relieve the fatigue and discomfort of the staff's hands through the action of the sponge ring 7, thereby improving the staff's work experience.

[0030] Working principle: when working, first place the electric actuator housing to be processed in the middle of the two sets of splints 14, then hold the handle 19 and pull it to drive the rack plate 18 to move. Because the rack plate 18 and the gear 17 are in a meshing state, the movement of the rack plate 18 will drive the gear 17 to rotate. At the same time, the rotation of the gear 17 will drive the bidirectional threaded rod 13 to rotate. The rotation of the bidirectional threaded rod 13 can push the two sets of splints 14 to move closer to each other, and the splints 14 will drive the oblique rod 15 to slide in the middle of the slide groove 16 when they move to a certain position, which can clamp the electric actuator housing. This step can clamp the electric actuator housing through the splint 14, thereby preventing the electric actuator from being damaged. During production, it is easily affected by mechanical forces and its position is offset, thereby causing the shell position to deviate from the predetermined position, thereby reducing processing accuracy, causing losses, and causing waste of raw materials. Through the interaction of the inclined rod 15 and the slide groove 16, the auxiliary splint 14 can maintain stability during movement, thereby improving the stability of the splint 14 clamping. During operation, when the two-way threaded rod 13 rotates, the belt 22 will be affected by friction and drive the driven shaft 2 to rotate. The rotation of the driven shaft 2 will drive the connecting column 23 and the arc-shaped brush plate 24 to rotate, and the bristles at the bottom of the arc-shaped brush plate 24 will come into contact with the rack plate 18 when the arc-shaped brush plate 24 rotates, thereby cleaning the rack plate 18. This step can be done by the arc-shaped brush plate 24. The rack plate 18 is used for cleaning to prevent the electric actuator from generating certain debris during production and processing, and the debris will be scattered everywhere due to the influence of the mechanical processing force, thereby causing some debris to fall onto the surface of the rack plate 18, affecting the meshing state of the rack plate 18 and the gear 17. During operation, when the rack plate 18 is pushed, the L-shaped guide column 31 will drive the U-shaped plate 32 and the groove roller 34 to move with the movement of the rack plate 18. Because the groove roller 34 is in contact with the surface of the platform 1, it will generate friction with the groove roller 34 when moving, and drive the rotating shaft 33 to rotate in the middle of the U-shaped plate 32 under the influence of the friction force. And because the groove of the groove roller 34 is stuck in the guide rail 3, the groove roller 34 is rotated. The L-shaped guide post 31 is provided to support the rack plate 18, thereby providing a certain supporting force for the rack plate 18, making the rack plate 18 more stable when moving. The groove roller 34 and the guide rail 3 cooperate with each other to limit the movement trajectory of the rack plate 18, thereby preventing the rack plate 18 from easily deviating left and right due to uneven force when moving, thereby affecting the situation in which the two-way threaded rod 13 is driven to rotate. During operation, when the splints 14 move closer to each other, they will drive the pillar 4 and the extrusion plate 41 and the extrusion block 44 to move. When the extrusion block 44 contacts the electric actuator housing, it will be subjected to a certain pressure and transmit the pressure to the tension spring 43.In this way, the tension spring 43 is forced to compress until the extrusion block 44 is in close contact with the shell, and the moving clamp 14 can be stopped. This step is because most of the electric actuator shells are irregular in shape, which easily causes the contact area between the clamp 14 and the shell to be limited, thereby reducing the clamping effect on the shell, and then it is easy for the shell to be positionally offset during production and processing. At this time, the extrusion block 44 and the tension spring 43 can cooperate with each other to adapt to various shapes, thereby increasing the clamping area of the shell, thereby reducing the occurrence of such situations. When working, the hollow disc 5 and the support rod 51 can cooperate with each other to help the support leg 11 maintain stability. This step is achieved through the hollow disc 5 and the support rod 51. The function of the rod 51 can reduce the positional displacement of the support leg 11 caused by the influence of the mechanical processing force during the production of the shell. During operation, when the extrusion block 44 clamps the shell, the anti-slip pad 6 will contact the shell before the extrusion block 44, thereby increasing the friction between the shell and the extrusion block 44. This step can further enhance the clamping effect of the extrusion block 44 through the function of the anti-slip pad 6, thereby making the shell more stable during production and processing. During operation, when the staff member holds the handle 19 to pull, the sponge ring 7 can increase the comfort of their hands. This step can relieve the fatigue and discomfort of the staff member's hands through the function of the sponge ring 7, thereby improving the staff member's work experience.
