Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic switch assembly, in particular to an assembly tool for an electromagnetic switch upper cover and a main body. Background Art

[0002] Simply put, an electromagnetic switch is a combination of an electromagnet and a switch. When the electromagnet coil is energized, it generates electromagnetic attraction, and the movable iron core pushes or pulls the switch contacts to close, thereby connecting the controlled circuit. An electromagnetic switch primarily consists of a top cover, a main housing, a coil, a movable iron core, and terminal blocks. The terminal blocks are mounted on the top cover, while the coil and movable iron core are located inside the main housing.

DETAILED DESCRIPTION

[0021] In order to make the technical purpose, technical solution and beneficial effects of the present invention clearer, the following Figure 1-4 The technical solution of the utility model is further illustrated with specific embodiments. Example

[0022] A tool for assembling the upper cover and the main body of an electromagnetic switch includes a stand 1 and two pneumatic screwdrivers. A mounting platform is installed on the stand 1. A longitudinal moving mechanism is provided between the mounting platform and the stand 1. The mounting platform includes a vertical plate 2, an upper horizontal plate 3 and a lower horizontal plate 4. The upper horizontal plate 3 and the lower horizontal plate 4 are both fixedly connected to the vertical plate 2. The pneumatic screwdriver includes a main unit 5 and a tool head 6. The pneumatic screwdriver is a prior art, and the specific structure and working principle are not described in detail. In other embodiments, the pneumatic screwdriver can also be replaced with an electric screwdriver. The main unit 5 of the pneumatic screwdriver is fixed by the upper horizontal plate 3.

[0023] The bottom of the lower horizontal plate 4 is detachably fixed with a mounting base 8 for mounting two pneumatic screwdriver tool heads 6. A limit post 9 is also installed on the mounting base 8. The limit post 9 is located between the two tool heads 6 and parallel to the axis of the tool heads 6. The middle part of the electromagnetic switch cover is raised, and the assembly screws 15 between the cover and the main body are located below the two sides of the raised position 14 ( Figure 4 The assembly screw 15 shown in the figure is one of them), the distance between the bottom end of the limit column 9 and the bottom end of the tool head 6 matches the shape of the electromagnetic switch cover, and the limit column 9 can prevent damage to the tool head 6 or the electromagnetic switch.

[0024] A workbench 10 is fixed to the bottom of the stand 1, and a positioning seat 11 for placing the electromagnetic switch is installed on the workbench 10. A positioning column matching the hole position at the bottom of the electromagnetic switch is provided on the positioning seat 11, which can make the electromagnetic switch in a suitable assembly position.

[0025] Working principle: First, place the electromagnetic switch to be assembled on the positioning seat 11, and then use the longitudinal moving mechanism to make the mounting table drive the pneumatic screwdriver to move downward. After the tool head 6 of the pneumatic screwdriver contacts the assembly screw 15, the pneumatic screwdriver starts, and the tool head 6 can tighten the assembly screw 15 to complete the assembly.

[0026] Furthermore, as one embodiment of the present invention, the longitudinal movement mechanism includes a slide rail 12, a slide seat, and a longitudinal telescopic member 13. The slide rail 12 is vertically fixed to the upright frame 1, the slide seat is fixed to the rear side of the upright board 2, the slide seat is slidably connected to the slide rail 12, and the telescopic rod of the longitudinal telescopic member 13 is fixedly connected to the upright board 2. In this embodiment, the longitudinal telescopic member 13 is a pneumatic cylinder. When the telescopic rod of the cylinder is extended downward, the pneumatic screwdriver can move downward with the upright board 2.

[0027] Furthermore, as one of the embodiments of the present invention, the main body 5 and the tool head 6 of the pneumatic screwdriver are connected by a movable universal joint 7, and the movable universal joint 7 is located between the upper horizontal plate 3 and the lower horizontal plate 4. The lower horizontal plate 4 includes a fixed block 41 and an adjustment block 42 that can expand or reduce the distance relative to the fixed block 41. The bottom of the movable universal joint 7 of one pneumatic screwdriver is installed on the fixed block 41, and the bottom of the movable universal joint 7 of the other pneumatic screwdriver is installed on the adjustment block 42.

[0028] In different models of electromagnetic switches, the spacing between the assembly screws 15 between the upper cover and the main body may vary. At this time, by fine-tuning the spacing between the fixing block 41 and the adjustment block 42, and replacing the mounting seat 8 corresponding to the spacing between the two pneumatic screwdriver tool heads 6, the assembly tooling of the present application can be made more widely applicable.

[0029] Furthermore, as one of the embodiments of the present invention, Figure 3 As shown, the fixed block 41 is provided with a U-shaped notch, with a support plate 44 fixed outside the U-shaped notch. The adjustment block 42 is slidably connected to the U-shaped notch of the fixed block 41. The adjustment block 42 is internally threaded with a screw shaft 43. The ends of the screw shaft 43 extend out of the adjustment block 42 and are respectively rotatably connected to the fixed block 41 and the support plate 44. To fine-tune the distance between the fixed block 41 and the adjustment block 42, the screw shaft 43 is rotated, and the adjustment block 42 moves closer to or away from the fixed block 41.

[0030] Furthermore, as one of the embodiments of the present invention, a handle 45 is installed at one end of the screw shaft 43 extending out of the support plate 44, which is convenient for holding to drive the screw shaft 43 to rotate.
