Description

Technical Field

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

[0002] A relay generally includes a magnetic circuit system, a contact system, and a restoration mechanism, wherein the magnetic circuit system includes parts such as an iron core, a yoke, an armature, and a coil; the contact system includes parts such as a static spring, a moving spring, and a contact base; and the restoration mechanism is a restoration spring or a tension spring. These parts are respectively installed in the main housing and the upper cover. During the assembly process of the relay, after the main housing and the upper cover are assembled, the main housing and the upper cover need to be assembled and connected by screws. In the specific assembly work, four screws are required to connect the main housing and the upper cover. If the screws are only tightened manually, it is time-consuming and labor-intensive, which is not conducive to improving work efficiency. Even if the manual screwdriver is replaced with an electric screwdriver, only one screw can be tightened at a time. Therefore, it is necessary to design an automatic assembly tool that is adapted to the structure of the relay upper cover and the main housing to improve assembly efficiency. Utility Model Content

DETAILED DESCRIPTION

[0019] 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

[0020] A relay cover and body assembly tool includes a stand 1 and four pneumatic screwdrivers. A mounting platform is installed on the stand 1. The mounting platform slides up and down along the stand 1 through a longitudinal moving mechanism. 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 stand 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 repeated here. 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.

[0021] The bottom of the lower horizontal plate 4 is fixedly connected to a leveling plate 9 through a support column 8. A leveling block 10 is detachably fixed to the leveling plate 9. The tool head 6 of the pneumatic screwdriver passes through the leveling block 10 and the leveling plate 9 and extends downward. The tool heads 6 of the four pneumatic screwdrivers are axially parallel.

[0022] A workbench 11 is fixed to the bottom of the stand 1, and a positioning seat 12 for placing the relay and a clamping assembly for fixing the relay are installed on the workbench 11. The positioning seat 12 is provided with holes that match the shape of the relay.

[0023] Working Principle: Because a relatively large number of pneumatic screwdrivers can be used simultaneously, the tool head 6 must be positioned at the appropriate height before use. This requires leveling. Leveling blocks 10 of varying heights can be selected, or different numbers of shims can be stacked on top of the blocks 10 to adjust the height of the tool head 6. The relay to be assembled is then placed on the positioning seat 12, clamped with a clamping assembly. The mounting platform then uses a longitudinal movement mechanism to move the pneumatic screwdriver downward. Once the pneumatic screwdriver's tool head 6 contacts the assembly screw 19, the pneumatic screwdriver activates, tightening the assembly screw 19 to complete assembly. After tightening, the pneumatic screwdriver resets and shuts off. The clamping assembly releases the relay, allowing it to be removed. Figure 4 In the relay structure shown in , four assembly screws 19 are symmetrically arranged with respect to each other, and two of the assembly screws 19 are shown in the figure.

[0024] Furthermore, as one embodiment of the present invention, the longitudinal movement mechanism includes a slide rail 13, a slide seat, and a longitudinal telescopic member 14. The slide rail 13 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 13, and the telescopic rod of the longitudinal telescopic member 14 is fixedly connected to the upright board 2. In this embodiment, the longitudinal telescopic member 14 is a cylinder.

[0025] 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 movable universal joint 7 can make the axis of the main body 5 and the tool head 6 of the pneumatic screwdriver not in a straight line, so as to facilitate the adjustment of the relative positions of the tool heads 6 of each pneumatic screwdriver.

[0026] Furthermore, as one of the embodiments of the present invention, four guide cylinders 15 are fixed to the bottom of the adjustment plate, and the guide cylinders 15 correspond one-to-one to the tool heads 6 of the pneumatic screwdriver. Since the four tool heads 6 work at the same time, the guide cylinders 15 can ensure that the downward movement direction of the four tool heads 6 can remain consistent with the position of the assembly screws 19 corresponding to the relay cover, thereby avoiding the tool head 6 from being skewed with the corresponding assembly screws 19.

[0027] Furthermore, as one embodiment of the present invention, the clamping assembly includes a bidirectional cylinder 16, a connecting rod 17, and a clamping handle 18. The bidirectional cylinder 16 is fixed to the workbench 11. The two telescopic rods of the bidirectional cylinder 16 extend to the left and right sides respectively, and the telescopic rods are connected to the clamping handle 18 via the connecting rod 17. When the two telescopic rods of the bidirectional cylinder 16 are retracted, the two clamping handles 18 can firmly grasp the relay placed on the positioning seat 12, avoiding the shaking that may be caused by tightening four assembly screws 19 at the same time, creating favorable conditions for the smooth completion of assembly.
