Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic switch assembly, in particular to a rapid assembly mechanism for an electromagnetic switch. Background Art

[0002] In the process of producing electromagnetic switches, multiple independent components need to be assembled together. For example, the moving iron core, coil, return spring and other components need to be placed in the housing in an orderly manner, and then the terminal is installed at the end of the housing through bolts to realize the assembly of the electromagnetic switch.

[0003] When connecting the terminal and the housing, it is necessary to control the rotation of the bolt under the action of the screwdriver so that it can be inserted into the threaded groove of the housing. This operation requires the staff to hold the screwdriver and rotate it continuously for multiple turns. In addition, the staff is faced with a large number of installation tasks of the terminal and the housing. Therefore, although it is a simple repetitive action for the staff, the continuous rotation of the screwdriver for a long time can easily cause arm injuries to the staff, and the efficiency is low, which affects the production of batch electromagnetic switches.

[0004] In order to improve the production efficiency of electromagnetic switches, production factories will also spend money to equip electric screwdrivers. There are many types of electric screwdrivers. For example, a Chinese patent with publication number CN101346215A discloses a small, lightweight, quickly rechargeable electric screwdriver and an electric screwdriver device that can reduce operating costs. The electric screwdriver of this invention stores or installs all the functions of the electric screwdriver except the charger in, for example, a resin shell, the shell has a roughly cylindrical barrel portion that rotatably supports a tool bit clamp at a front opening, a handle portion that is separated downward from the barrel portion at a roughly right angle or obtuse angle when viewed from the tool bit clamp side, and the barrel portion stores a brake switch, a clutch, a gear, a motor, a printed circuit board, an electric double layer capacitor, etc. For example, a Chinese patent with publication number CN105682859B discloses an electric screwdriver, in which an electric screwdriver accessory is installed on the electric screwdriver body. The electric screwdriver body comprises: an electric screwdriver drive control circuit arranged in the screwdriver housing, a power cord connected to the electric screwdriver drive control circuit and passing through a first power cord retaining hole, and a power cord fixing annular component fixed to the outer periphery of the power cord.

[0005] When using the screwdriver provided by the above patent to assemble the electromagnetic switch, the staff needs to hold the electric screwdriver, aim at multiple bolts one by one, control the electric screwdriver to drive the bolts to rotate, and complete the connection between the terminal and the housing. Compared with manually turning the bolts, this connection method reduces the labor intensity and improves the efficiency. However, if more than two bolts can be controlled to rotate at the same time, the assembly efficiency of the electromagnetic switch will be further improved. Utility Model Content

[0028] Example 1

[0029] In the production of electromagnetic switches, it is necessary to install the terminal blocks on the end with various components installed inside through bolt connections. In order to complete this step, the staff needs to hold a screwdriver or an electric screwdriver to turn multiple bolts one by one. This method is inefficient and is not conducive to the assembly of batch electromagnetic switches. In order to solve this problem, the inventor of this patent has set up an assembly mechanism that can improve assembly efficiency according to actual needs. The specific scheme of the assembly mechanism is shown below.

[0030] like Figure 1 , Figure 3 , Fig. 9 As shown, the assembly mechanism includes a handle 1, a motor 2, a support frame 4, a transmission device 5 and a rotating device 6. The motor 2 is inverted, and the handle 1 and the support frame 4 are respectively arranged on the upper and lower sides of the motor 2. There are at least two groups of rotating devices 6, and both are adjustable and arranged on the support frame 4, and connected to the output shaft of the motor 2 through the transmission device 5, so as to control the rotation of multiple groups of rotating devices 6 under the operation of the motor 2. Before using the device to complete the assembly of the electromagnetic switch, the staff needs to place the terminal on the housing, and set multiple terminals through the terminal, and at the same time, the end is facing the thread groove of the housing, and then, the multiple groups of rotating devices 6 with adjusted spacing are placed facing the multiple bolts, so that the rotation of the rotating device 6 controls the simultaneous rotation of the multiple bolts and the end is immersed in the thread groove. This operation changes the current situation of rotating the bolts one by one, and improves the assembly efficiency of the electromagnetic switch.

[0031] like Figure 1 , Figure 2 As shown, in order to facilitate the staff to hold the device, a flower stand is provided at the lower end of the handle 1, and a connecting rod 11 is vertically provided below the end corner of the flower stand. An end column 12 is fixedly provided at the lower end of the connecting rod 11. The end corner of the motor 2 housing is provided as an arc groove, one end of the arc groove is provided as a closed structure, and a through hole is provided at the closed structure.

This arrangement allows the support frame 4 and the motor 2 to be stably installed below the handle 1, so that the staff can control the movement of the device by holding the handle 1. In order to facilitate the control of the operation of the motor 2, a control switch is provided on the handle 1, and the control switch is electrically connected to the motor 2.

The number of the second wheel bodies 53 is one more than the number of the rotating devices 6, so that the connecting member 52 can be pulled to move by the redundant second wheel body 53, and the connecting member 52 is in a tensioned state to provide a possibility.

[0033] The first wheel body 51 and the second wheel body 53 can be set as pulleys or sprockets. If they are set as pulleys, the connecting member 52 is set as a belt, and the belt can be a synchronous belt with teeth and has a strong tension. If they are set as sprockets, the connecting member 52 is set as a chain, and the tension of the chain can be moderate. In short, the first wheel body 51 and the second wheel body 53 can achieve effective transmission.

[0034] like Figure 8 As shown, in order to control the rotation of the bolt, the rotating device 6 includes a connecting shaft 64 and a screwdriver 61. A keyway 62 is provided on the top of the screwdriver 61, and a slot 63 is provided on the lower end surface of the connecting shaft 64. A structure adapted to the keyway 62 is provided on the side wall of the slot 63. The upper end of the screwdriver 61 is connected by a bolt and inserted into the slot 63.
