[0002] The main function of an electric motor is to generate driving torque, serving as a power source for electrical appliances or various machines. An electric motor generally consists of a stator, rotor, brushes, and housing. After each part is manufactured, workers typically assemble the components. To further protect the assembled motor from external environmental influences, workers will install end caps on the assembled motor body.

[0003] In existing technology, a motor generally includes a motor body and end covers. A conventional end cover includes a front cover attached to the front of the motor body, a rear cover attached to the rear of the motor body, and several bolts connecting the shell edges of the front and rear covers. These bolts secure the front and rear covers to the motor body, thus protecting the motor body. However, before the front and rear covers are securely connected with bolts, their assembly on the motor body is unstable. When operators manually assemble the bolts, the accuracy is low, affecting the assembly efficiency of the motor body and the front and rear covers, and reducing motor production efficiency to some extent. Therefore, a screw clamping fixture for motor assembly is provided to solve the above problems. Utility Model Content

Through the cooperation of the support assembly 11 and the lifting plate 13, the motor 20 is clamped and fixed, thus facilitating the assembly of the motor body 21, the first end cover 22, and the second end cover 23 with bolts, and improving the assembly efficiency of the motor 20 to a certain extent.

[0030] Please see Figures 1-4As shown, in this embodiment, the support assembly 11 includes two support side plates 111, a mounting plate 112, and a clamping plate 113. The two support side plates 111 are arranged in parallel and vertically, forming the main support body. The mounting plate 112 and the clamping plate 113 are respectively fixedly connected horizontally between the two support side plates 111, and the lifting plate 13 is arranged opposite to the clamping plate 113. Specifically, the mounting plate 112 has multiple mounting holes 1121 through it, and the lifting drive assembly 12 is fixedly mounted on the mounting plate 112 through the multiple mounting holes 1121. The clamping plate 113 has a through hole 1131 through it, which facilitates the assembly operation of the motor 20.

[0032] Please see Figure 4 and Figure 5 As shown, in this embodiment, the cylinder mechanism 121 includes a fixed plate 1211 and a cylinder body 1212. The fixed plate 1211 is fixedly connected to the mounting plate 112 through multiple mounting holes 1121. The cylinder body 1212 is fixedly mounted on the fixed plate 1211 and passes through the mounting plate 112. The lifting plate 13 is drivenly connected to the cylinder body 1212. The cylinder body 1212 drives the lifting plate 13 to move up and down in the longitudinal direction, so that the second end cover 23 on the motor 20 mounted on the lifting plate 13 is tightly connected to the clamping plate 113, thereby clamping the motor 20 tightly between the lifting plate 13 and the clamping plate 113.

[0033] Please see Figure 4 and Figure 5As shown, in this embodiment, the air supply control mechanism 122 includes a control air chamber 1221, a pneumatic switch 1222, and a pneumatic copper silencer 1223. The control air chamber 1221 is fixedly mounted on the support side plate 111. The pneumatic switch 1222 and the pneumatic copper silencer 1223 are respectively disposed on the control air chamber 1221. The pneumatic switch 1222 controls the air supply operation to the cylinder mechanism 121, and the pneumatic copper silencer 1223 reduces the noise generated during operation. Specifically, the control air chamber 1221 is respectively connected to an air inlet 12211 and an air outlet 12212. The air inlet pipe mechanism 124 is connected to the air inlet 12211, and the air outlet pipe 123 is connected to the air outlet 12212. Specifically, the intake pipe mechanism 124 includes a speed regulating throttle valve 1241 and an intake pipe 1242; one end of the speed regulating throttle valve 1241 is connected to the intake port 12211, and the amount of gas entering the control air chamber 1221 is adjusted by the speed regulating throttle valve 1241; one end of the intake pipe 1242 is connected to the speed regulating throttle valve 1241, and the other end is connected to the air supply equipment.

[0035] It should be noted that the specific assembly process of the screw clamping fixture 10 for motor assembly of this utility model is as follows: First, the motor 20 is placed on the lifting plate 13. At the same time, the first end cover 22 is limited by the limiting groove 132, and the positioning column 24 is positioned by passing through the positioning notch 1132 through the clamping plate 113. Then, the pneumatic switch 1222 is pressed, and the gas in the gas supply device enters the cylinder body 1212 through the inlet pipe 1242, the speed regulating throttle valve 1241, the control air chamber 1221, and the outlet pipe 123 in sequence. This causes the cylinder body 1212 to drive the motor 20 set on the lifting plate 13 to move upward, so that the second end cover 23 contacts and connects with the clamping plate 113, thereby fixing the motor 20 between the lifting plate 13 and the clamping plate 113. This makes it convenient for the user to fix the bolts on the motor 20, thus completing the assembly operation of the motor body 21, the first end cover 22, and the second end cover 23.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
