[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0028] See also Figure 1-3 , an embodiment of the present invention includes: a fixing seat is provided on the top of the fixing plate, the end of the handle is movably connected to the fixing seat, and the handle adopts the lever principle and drives the pressing plate to move up and down through the linkage mechanism,

[0029] An assembly jig for a power switch can fix a nut in an upper cover, making it convenient to connect the power switch and the nut and fix it in the upper cover 5. Its structure includes: a base 1, a sliding groove 2, a sliding platform 3, a limit block 4, a limit groove, a nut mounting unit, and a lifting drive unit for driving the nut mounting unit to move up and down. The nut mounting unit can be used to fix the nut of the power switch, so as to ensure that the nut and the power switch are successfully aligned in one go and prevent the nut from rotating when assembling the power switch.

[0030] The sliding groove is arranged on the top of the base, and the sliding platform moves back and forth in the sliding groove. A track is provided in the sliding groove, and the track is movably connected to the sliding platform so that the product can accurately reach the predetermined assembly position, which is convenient for the operators to assemble and take. A handle is provided on the sliding platform to facilitate the user to push and pull the sliding platform, thereby improving work efficiency.

[0031] The limit block is arranged on the sliding platform, the limit groove is arranged on the limit block, and the base is provided with a limit block that cooperates with the sliding platform. The position structure of the limit block and the position structure of the limit groove need to be adjusted and installed according to different upper cover structures to further improve the installation accuracy and efficiency.

[0032] The upper cover of the product is provided with an installation groove for installing a nut. The side wall of the installation groove is provided with a through hole for connecting the power switch. The connecting shaft of the power switch needs to pass through the through hole to connect with the nut, thereby fixing the power switch in the upper cover. The nut installation unit includes a guide column 6, a movable seat 7, a mounting bracket 8 and a mounting hole 9 for placing and fixing the nut. The guide column is provided on the base. The movable seat is movably connected to the guide column. The movable seat is provided with a movable bearing allowing the guide column to pass through. The lifting drive unit drives the movable seat to move up and down on the guide column. The mounting bracket is movably provided at the bottom of the movable seat. The mounting hole is provided on the mounting bracket. The shape and size of the mounting hole can be set according to the shape and size of the nut. Generally, the mounting hole is a hexagonal structure, and the size of the mounting hole is slightly larger than the nut, so that the nut can be fixed in the mounting hole to prevent it from loosening and falling, and also to prevent the nut from being stuck in the mounting hole and unable to escape. The mounting bracket is located above the sliding platform.

[0033] The lifting drive unit may be an electrically controlled structure, for example, comprising a driving cylinder, the output shaft of which is connected to the movable seat. The lifting drive unit comprises a servo motor, a lead screw nut, and a lead screw, wherein the lead screw nut is threadedly connected to the lead screw, which is connected to the movable seat. The servo motor is connected to the lead screw and drives the lead screw to rotate, so that the lead screw nut drives the movable seat to move up and down.

[0034] In addition, upper and lower pull rods can be designed to facilitate the nut to reach the predetermined assembly position, facilitate operation, and reduce costs. At this time, the lifting drive unit includes a control handle 10, a fixed seat 11, an axle seat 12, a rotating connector 13, and a linkage shaft 14. The fixed seat is arranged on the base, and the axle seat is arranged on the top of the fixed seat. The control handle is an L-shaped structure, one end of the control handle is rotatably connected to the axle seat, the upper end of the rotating connector is rotatably connected to the bend of the control handle, and the lower end of the rotating connector is rotatably connected to the upper end of the linkage shaft. Each connecting joint can rotate in all directions and at multiple angles, thereby realizing accurate and rapid up and down vertical movement of the crimping plate, and rapid clamping and positioning. The lower end of the linkage shaft is connected to the movable seat.

[0035] The handle adopts the lever principle and drives the movable seat to move up and down through the rotating connecting piece and the linkage shaft. When the handle is lifted upward, the handle drives the connecting piece upward. At the same time, the linkage shaft drives the pressing plate to move upward along the two-way guide column under the traction of the connecting piece, and the installation hole is away from the upper cover. When the handle is pressed downward, the handle drives the connecting piece downward. At the same time, the linkage shaft drives the pressing plate to move downward along the two-way guide column under the push of the connecting piece, and the installation hole enters the upper cover to install the power switch.

[0036] The working steps of an assembly jig for a power switch include:

[0037] Step 1: Place the product cover on the sliding platform, and use the limit blocks and limit slots to limit and fix the cover, and then push the sliding platform to the designated position;

[0038] Step 2: Lift the control handle, the mounting bracket will rise, and place the nut into the mounting hole;

[0039] Step 3: Press the control handle, and the lifting drive device drives the movable seat and the mounting frame to descend and enter the pre-installation position (mounting slot) of the upper cover;

[0040] Step 4: Manually pass the connecting shaft on the power switch through the through hole and rotate it into the nut. Then use a ratchet wrench to clamp the power switch body and quickly tighten it. As the power switch is tightened, the nut will gradually move away from the mounting hole until it is completely disengaged.

[0041] Step 5: Move the sliding platform to its initial position and lift the nut mounting module to take out the product.

[0042] The beneficial effects of the assembly jig for a power switch of the present invention are:

[0043] 1. Improve the assembly efficiency of operators and reduce the difficulty of product assembly;

[0044] 2. Reduce the management cost of products that are scratched and scrapped due to manual assembly;

[0045] 3. Improve customer satisfaction.

[0046] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
