[0020] The following will be combined with the attached embodiment of the present invention Figure 1-8 , clearly and completely describe 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 them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] As shown in the figure, a rotor assembly device of a combination switch includes a base plate 1, a bracket 2, a positioning seat 3, a positioning cylinder 4, a positioning pressure plate 5, a first clamping cylinder 6, a first clamping block 7, a second clamping cylinder 8 and a second clamping block 9. The positioning seat 3 is fixedly arranged on the base plate 1 and a material placement groove 31 is formed on the positioning seat 3. The shape of the material placement groove 31 matches the shape of the base 1a. After the base 1a is placed in the material placement groove 31, a horizontal limit is applied to the base 1a. The bracket 2 is fixedly arranged on the base plate 1 and located on one side of the positioning seat 3. The positioning cylinder 4 is vertically arranged on the bracket 2. Specifically, the positioning cylinder 4 is a sliding cylinder and the output shaft of the positioning cylinder 4 is arranged downward. The positioning pressure plate 5 is fixedly arranged on the sliding seat of the positioning cylinder 4 and located above the positioning seat 3. The first clamping cylinder 6 is fixedly arranged on the sliding seat of the positioning cylinder 4 and located above the positioning pressure plate 5. The first clamping cylinder 6 The output shaft of the first clamping cylinder 6 faces the positioning pressure plate 5, the first clamping block 7 is fixedly arranged on the output shaft of the first clamping cylinder 6, and the first clamping block 7 is formed with two first clamping push rods 71 ​​that downwardly penetrate into the through holes provided on the positioning pressure plate 5, the first clamping push rods 71 ​​are flat-plate-shaped, and the two first clamping push rods 71 ​​are respectively aligned in the longitudinal direction with the connection between the two return springs 3a and the spring clamping plate 2a when the spring clamping plate 2a and the return spring 3a are loaded on the base 1a, the second clamping cylinder 8 is horizontally arranged on the base plate 1 at one side of the positioning seat 3, and the output shaft of the second clamping cylinder 8 faces the positioning seat 3, the second clamping block 9 is fixedly arranged on the output shaft of the second clamping cylinder 8, and the second clamping block 9 is formed with two second clamping push rods 91, and the two second clamping push rods 91 are respectively aligned in the horizontal direction with the two return springs 3a when the spring clamping plate 2a and the return spring 3a are loaded on the base 1a.

[0022] When the rotor of the combination switch is assembled by the above structure, the base 1a is first placed on the positioning seat 3 and clamped into the material placement groove 31. The material placement groove 31 applies a horizontal limit to the base 1a so that the base 1a is stably maintained on the positioning seat 3 to realize the loading of the base 1a. At this time, there is a gap between the first clamping portion 1a1 on the base 1a and the positioning seat 3 for the second clamping portion 2a1 on the spring clamping plate 2a to be inserted. Then, the two reset springs 3a are respectively inserted into the two spring holes on the spring clamping plate 2a, and then the spring clamping plate 2a and the reset spring 3a are placed on the base 1a, so that the lower end of the second clamping portion 2a1 is inserted into the gap between the first clamping portion 1a1 and the positioning seat 3, and the other ends of the two reset springs 3a are placed on the spring seat on the base 1a. 1a2 are respectively aligned horizontally with the two second clamping push rods 91 to realize the loading of the spring clamp 2a and the return spring 3a, and then the assembly device starts to work. First, the positioning cylinder 4 drives the positioning pressure plate 5, the first clamping cylinder 6 and the first clamping block 7 to move toward the positioning seat 3. When the positioning pressure plate 5 moves to abut against the upper end of the positioning seat 3, the positioning pressure plate 5 abuts against the spring clamp 2a to impose a longitudinal limit on the spring clamp 2a. At the same time, the lower end of the second clamping portion 2a1 is inserted into the gap between the first clamping portion 1a1 and the positioning seat 3 to impose a horizontal limit on the spring clamp 2a, so that the spring clamp 2a and the return spring 3a are stably maintained on the base 1a, and then the second clamping cylinder 8 drives the second clamping block 9 to drive the second clamping push rod 91 Move toward the positioning seat 3, and the two second clamping push rods 91 respectively press against the ends of the two return springs 3a during the movement to compress the return spring 3a, so that the return spring 3a is compressed until the end is located above the inner side of the spring seat 1a2. Then the first clamping cylinder 6 drives the first clamping block 7 to drive the first clamping push rod 71 to move toward the positioning seat 3. The two first clamping push rods 71 ​​pass through the through holes on the positioning pressure plate 5 during the movement and press against the spring clamp plate and the two return springs 3a to push the spring clamp plate and the two return springs 3a downward, so that the return spring 3a is clamped between the spring clamp plate and the spring seat 1a2, and the second clamping portion 2a1 is clamped between the first clamping portion 1a1 and the positioning seat 3. When the second clamping portion 2a1 is pushed into place by the first clamping push rod 71 (that is, when the return spring 3a is completely inserted between the spring clamp 2a and the spring seat 1a2), the spring clamp 2a moves slightly on the base 1a under the restoring force of the return spring 3a, so that the first clamping portion 1a1 is clamped with the second clamping portion 2a1, thereby realizing the assembly of the spring clamp 2a, the return spring 3a and the base 1a. Through the above structure and assembly method, the rotor assembly operation of the combination switch is realized by a mechanical structure instead of manual operation, which can effectively avoid human errors during manual operation and ensure the accuracy of assembly. Moreover, during operation, it is only necessary to load the base 1a, the spring clamp 2a and the return spring 3a onto the positioning seat 3 in sequence, and the assembly operation can be completed automatically, thereby making the assembly easy to operate, saving manpower and improving the efficiency of assembly.

[0023] In addition, based on the above structure, a positioning protrusion 51 is formed on the lower surface of the positioning pressure plate 5, and two positioning grooves 52 are formed on the positioning protrusion 51. When the return spring 3a is loaded onto the base 1a, the positioning protrusion 51 is located above one end of the return spring 3a placed on the spring seat 1a2, and the two positioning grooves 52 are respectively aligned with the two return springs 3a in the longitudinal direction. When the positioning pressure plate 5 is driven by the positioning cylinder 4 to press against the spring clamping plate 2a, the two return springs 3a are respectively located in the two positioning grooves 52, and the positioning grooves 52 impose a limit on the return spring 3a, ensuring that when the second clamping push rod 91 compresses the return spring 3a, the return spring 3a will not produce radial deflection due to the force, thereby ensuring that when the first clamping push rod 71 pushes the return spring 3a downward, the return spring 3a can be accurately clamped between the spring clamping plate 2a and the spring seat 1a2, thereby ensuring the assembly accuracy.

[0024] In addition, based on the above structure, two upright guide rods 10 are fixedly provided on the base plate 1, the positioning pressure plate 5 is passed through the guide rods 10 and a sliding bearing 11 is provided between the positioning pressure plate 5 and the guide rod 10, the guide rod 10 and the sliding bearing 11 cooperate to provide a guiding effect when the positioning pressure plate 5 moves longitudinally, thereby ensuring the accuracy of the stability of the positioning pressure plate 5 when it is driven by the positioning cylinder 4 to move, thereby ensuring the accuracy of assembly.

[0025] In addition, on the basis of the above structure, a guide seat 12 located between the positioning seat 3 and the second clamping cylinder 8 is fixedly provided on the base plate 1, and a guide hole 121 is opened on the guide seat 12. The second clamping push rod 91 penetrates into the guide hole 121 so that the outer side surface of the second clamping push rod 91 is in contact with the inner side wall of the guide hole 121. When the second clamping push rod 91 is driven by the second clamping cylinder 8, it slides in the guide hole 121. The guide hole 121 improves the guiding effect of the movement of the second clamping push rod 91, ensuring that the second clamping push rod 91 moves to compress the reset spring 3a, thereby ensuring the stability and accuracy of assembly. Furthermore, a limiting protrusion 92 is formed on the outer surface of the second clamping push rod 91, and a limiting groove 122 matching the limiting protrusion 92 is formed on the inner wall of the guide hole 121. The limiting protrusion 92 is retained in the limiting groove 122. The limiting protrusion 92 and the limiting groove 122 cooperate to provide a limiting effect when the second clamping push rod 91 slides in the guide hole 121, thereby preventing the second clamping push rod 91 from swinging when it moves and compresses the reset spring 3a, thereby further ensuring the accuracy of assembly.

[0026] In addition, on the basis of the above structure, a T-shaped connecting groove 93 is provided on the end of the second clamping block 9 facing the second clamping cylinder 8, and a T-shaped cylindrical connecting column 13 is arranged in the connecting groove 93. The large end of the connecting column 13 is retained in the connecting groove 93, and the small end is screwed to the output shaft of the second clamping cylinder 8. The connecting column 13 is rotated to make it move axially along the output shaft of the second clamping cylinder 8. The connecting column 13 drives the second clamping block 9 and drives the second clamping push rod 91 to move axially along the output shaft of the second clamping cylinder 8 through cooperation with the connecting groove 93, thereby adjusting the stroke of the second clamping push rod 91 when it is driven by the second clamping cylinder 8, ensuring that the second clamping push rod 91 can compress the reset spring 3a to the position above the inner side of the spring seat 1a2, thereby ensuring that the first clamping push rod 71 can push the reset spring 3a downward to make it clamped between the spring clamp plate 2a and the spring seat 1a2 for assembly.

[0027] In addition, in the above structure, a pressure sensor 14 is fixedly provided on the inner wall of the connecting groove 93, and the large head end of the connecting column 13 is abutted against the pressure sensor 14. The pressure sensor 14 is connected to an external controller and an alarm. The specific connection structure is a common prior art and will not be elaborated here. When the second clamping cylinder 8 drives the second clamping block 9 and the second clamping push rod 91 to move the compressed reset spring 3a through the connecting column 13, the restoring force of the reset spring 3a is applied to generate pressure between the connecting column 13 and the pressure sensor 14. The restoring force of the reset spring 3a is detected by the pressure sensor 14 to determine whether the parameters such as the stiffness of the reset spring 3a meet the standard requirements. If the parameters of the reset spring 3a do not meet the standard requirements, the alarm will sound and the assembly action will be stopped through the controller, thereby ensuring the product quality of the rotor of the assembled combination switch.

[0028] In addition, on the basis of the above structure, a vertical guide groove 94 matching the first clamping push rod 71 is opened on the end of the second clamping push rod 91 facing the positioning seat 3. After the second clamping push rod 91 compresses the reset spring 3a into place, the end of the guide groove 94 is located below the first clamping push rod 71. When the first clamping push rod 71 moves downward to push the spring clamp 2a and the reset spring 3a, the first clamping push rod 71 is inserted into the guide groove 94 from top to bottom. The guide groove 94 provides a guiding effect for the movement of the first clamping push rod 71 to ensure that the first clamping push rod 71 can press against the reset spring 3a to reset the reset spring 3a is pushed into place, and because the guide groove 94 provides a path for the first clamping push rod 71 to pass through when the first clamping push rod 71 moves downward, the second clamping push rod 91 can increase the amount of compression of the return spring 3a by increasing the stroke, so that the return spring 3a can be more easily pushed by the first clamping push rod 71 to be stuck between the spring clamp plate 2a and the spring seat 1a2, and also when there is a protrusion on the inner side of the spring seat 1a2 that limits the return spring 3a, the first clamping push rod 71 can compress the return spring 3a to the upper inner side of the protrusion, thereby ensuring that the return spring 3a can be pushed and stuck on the protrusion by the first clamping push rod 71.

[0029] In addition, on the basis of the above structure, the positioning seat 3 can be longitudinally slidably penetrated with two support rods 15 respectively located on both sides of the notch of the positioning groove 52 away from the second clamping cylinder 8, and a support spring 16 is arranged under the support rod 15. The support spring 16 is located in the gap between the first clamping part 1a1 and the positioning seat 3 when the base 1a is loaded onto the positioning seat 3, and when the spring clamping plate 2a is loaded onto the base 1a so that the lower end of the second clamping part 2a1 is inserted into the first clamping part 1a1 and the positioning seat 3, the second clamping part 2a1 is placed on the support rod 15, and the support rod 15 provides support for the second clamping part 2a1 and then for the spring clamping plate 2a, thereby ensuring the stability of the spring clamping plate 2a when it is loaded onto the base 1a, and when the first clamping push rod 71 pushes the spring clamping plate 2a downward, the support rod 15 is forced to slide downward and compress the support spring 16.

[0030] In addition, on the basis of the above structure, a contact sensor 17 is arranged on the positioning seat 3, and the contact sensor 17 is in contact with an external controller and an alarm. Its specific connection structure is a common prior art and will not be elaborated here. After the base 1a is loaded onto the positioning seat 3, the base 1a contacts the contact sensor 17, and the contact sensor 17 detects whether the base 1a is correctly loaded onto the positioning seat 3. Otherwise, the alarm will sound an alarm when the assembly device is started. Here, the position where the contact sensor 17 is set corresponds to the positioning column 4a formed at the lower end of the base 1a, that is, when the base 1a is loaded onto the positioning seat 3, the positioning column 4a contacts the contact sensor 17 to confirm that the base 1a has been correctly loaded onto the positioning seat 3. The position where the contact sensor 17 is set can be adjusted accordingly according to the shape of the base 1a. It is a technical solution that can be clearly implemented by technical personnel in this field and will not be listed one by one here.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
