DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

[0024] like Figures 1 to 4 As shown, a gluing device for a double-column capacitor bushing includes a workbench 1, a rotating support platform, a bracket and a glue gun 2. The rotating support platform includes a drive motor 3, a support shaft 4 and a support platform 5. The drive motor 3 is installed on the workbench 1. The support shaft 4 is vertically arranged, with its upper end connected to the support platform 5 and its lower end connected to the drive shaft of the drive motor 3. The support platform 5 is horizontally arranged, the bracket is arranged on the workbench 1, and the glue gun 2 is arranged on the bracket.

[0025] The present embodiment provides a gluing device for a double-column capacitor bushing. Under its structural configuration, when gluing the double-column capacitor bushing, the double-column capacitor bushing is placed on a support platform 5, and one of the capacitor bushings is aligned with the axis of the support shaft 4. The nozzle of the glue gun 2 is aligned with the connection between the capacitor bushing and the stainless steel flange of the porcelain sleeve. The drive motor 3 then drives the support shaft 4 to rotate, thereby rotating the support platform 5. The rotation of the support platform 5 drives the double-column capacitor bushing to rotate. During the rotation process, the nozzle of the glue gun passes through the connection between the capacitor bushing and the stainless steel flange of the porcelain sleeve to achieve the gluing operation. After completing the gluing operation for one bushing, the positions of the two capacitor bushings are swapped, and the gluing operation is performed on the other capacitor bushing, finally completing the gluing operation for the entire double-column capacitor bushing. During the execution of the above process, only the position of the double-column capacitor bushing needs to be manually determined, and the gluing process is automatically performed, thereby significantly reducing the workload of workers, improving work efficiency, and improving the quality of gluing.

[0026] A double-column capacitor bushing gluing device of this embodiment also includes a clamping assembly, which includes a driving wheel 7 and multiple clamping units. The clamping unit includes a driven wheel 8, an adjusting screw 9, an adjusting rod 11, a positioning rod 14, a first abutting body 16, a second abutting body 18 and a clamping block. The clamping block includes a split clamping portion 19 and a supporting portion 20. The clamping portion 19 is rotatably arranged at the top end of the supporting portion 20. The circumference of the driven wheel 8 fits the circumference of the driving wheel 7. The adjusting screw 9, the adjusting rod 11 and the positioning rod 14 are vertically arranged. The lower end of the adjusting screw 9 is connected to the axle of the driven wheel 8, and the upper end is inserted into the In the clamping block, the support portion 20 is provided with a thread that cooperates with the adjusting screw 9, the lower end of the positioning rod 14 is fixed on the supporting platform 5, and the top of the positioning rod 14 is provided with a bending portion 15, and the bending portion 15 is connected to the side of the adjusting rod 11. The adjusting rod 11 includes a rectangular body 12 and a torsion section 13 provided at the top end of the rectangular body 12, and the torsion section 13 is formed by rectangular torsion. The first abutting body 16 and the second abutting body 18 are provided inside the clamping portion 19 and connected to the clamping portion 19. The first abutting body 16 and the second abutting body 18 respectively abut against the two opposite sides of the adjusting rod 11.

[0027] Under the above structural setting, when the driving wheel 7 is rotated, the driving wheel 7 drives the driven wheel 8 to rotate, and the rotation of the transmission wheel drives the rotation of the adjusting screw 9. During the rotation process, the adjusting screw 9 cooperates with the thread provided in the support part 20, so that the support part 20 moves upward or downward, thereby causing the clamping block to move upward or downward as a whole. When the clamping block moves upward to a certain position, that is, when the first abutting body 16 and the second abutting body 18 contact the torsion section 13, due to the shape setting of the torsion section 13, the first abutting body 16 and the second abutting body 18 will rotate around the torsion section 13, and the rotation of the first abutting body 16 and the second abutting body 18 drives the clamping part 19 to rotate. During the above movement process, the positioning rod 14 realizes the positioning and guiding of the support part 20, prevents the support part 20 from rotating, and also enables the clamping part 19 and the support part 20 to rotate relative to each other. Under such a setting, when the clamping block moves downward to a certain position, the clamping block clamps the capacitor porcelain sleeve stainless steel bottom plate of the double-column capacitor bushing; when the clamping block moves upward to a certain position, the clamping portion 19 rotates, and the clamping block is removed from the capacitor porcelain sleeve stainless steel bottom plate, thereby realizing the automatic swinging of the clamping portion 19, thereby releasing the blocking of the capacitor porcelain sleeve stainless steel bottom plate by the clamping block, making it easier to take and place the capacitor porcelain sleeve stainless steel bottom plate.

[0028] In order to make the adjustment rod 11 more stable, a slot 10 is provided at the top of the adjustment screw 9, and the lower end of the adjustment rod 11 is inserted into the slot 10. After being inserted into the slot 10, it can be supported by the adjustment screw 9, thereby improving stability and reducing the burden on the bending part 15.

[0029] In order to realize the rotation setting between the support part 20 and the clamping part 19, a connecting ring 22 is provided at the upper end of the support part 20, and the connecting ring 22 includes a connecting part 23 and a limiting part 24 connected to each other. The lower end of the clamping part 19 is provided with a connecting groove 21, and the shape of the connecting groove 21 is adapted to the shape of the connecting ring 22. The connecting ring 22 is limited in the connecting groove 21, so that the clamping part 19 can rotate relative to the support part 20.

[0030] In the clamping state, the first abutting body 16 and the second abutting body 18 are in a lower position. When the driving wheel 7 is accidentally rotated, the position of the clamping part 19 will change, resulting in a lack of clamping force. In order to achieve the locking of the clamping state, the following settings are provided: the clamping unit also includes a lifting screw 25, and a lifting screw hole 17 is provided on the first abutting body 16. The lifting screw 25 is inserted into the clamping part 19 from top to bottom and cooperates with the lifting screw hole 17. The second abutting body 18 is fixedly connected to the clamping part 19. When locking, the lifting screw 25 is rotated, and the first resisting body 16 is raised to the position of the lower end of the torsion section 13 through the cooperation relationship between the lifting screw 25 and the first resisting body 16. At this time, there is a height difference between the first resisting body 16 and the second resisting body 18. When the driving wheel 7 has a tendency to move, according to the relevant linkage relationship, the driving wheel 7 cannot rotate due to the obstruction of the first resisting body 16, thereby realizing the locking of the clamping state and ensuring a stable clamping state. When it is necessary to contact this locked state, the position of the first resisting body 16 is controlled by the lifting screw 25, so that it is restored to the same height as the second resisting body 18, thereby achieving normal unlocking.

[0031] As to how to restore the first abutting body 16 to the same height as the second abutting body 18 , this can be achieved by providing an observation opening on the side of the clamping block or by providing a scale corresponding to the thickness of the stainless steel bottom plate of the capacitor porcelain sleeve.

[0032] Specifically, the first abutting body 16 and the second abutting body 18 are configured to be in the shape of a sheet, a block or a rod.

[0033] In order to achieve a reasonable structural setting, an accommodating cavity 6 is provided inside the support platform 5 , and the driving wheel 7 and the driven wheel 8 are arranged in the accommodating cavity 6 .

[0034] In order to facilitate the rotation of the driving wheel 7, the clamping assembly also includes a control wheel 26 and a crank 27. The circumference of the control wheel 26 fits the circumference of the driving wheel 7. The crank 27 is installed on the supporting platform 5 and connected to the axle of the control wheel 26. By rotating the crank 27 in different directions, the driving wheel 7 can be controlled in different rotation directions.

[0035] Furthermore, the bracket includes a longitudinal frame 28 and a transverse frame 29 . The lower end of the longitudinal frame 28 is mounted on the workbench 1 . The transverse frame 29 is connected to the longitudinal frame 28 . The glue gun 2 is mounted on the longitudinal frame 28 .

[0036] Specifically, an adjustment block 30 is provided at one end of the transverse frame 29. The adjustment block 30 is provided with a longitudinal insertion hole and a transverse tightening screw hole. A tightening bolt 31 is provided in the tightening screw hole. The longitudinal frame 28 passes through the insertion hole, and the tightening bolt 31 abuts against the longitudinal frame 28. By adjusting the position of the adjustment block 30, the height of the glue gun 2 can be adjusted. A positioning block 32 is provided at the bottom of the longitudinal frame 28. The positioning block 32 has a longitudinal positioning through hole. The workbench 1 has a positioning hole corresponding to the position of the positioning through hole. A positioning rod 33 is provided in the positioning through hole, and the positioning rod 33 is inserted into the positioning hole. When the positioning rod 33 is inserted into the positioning hole, the bracket is fixed, and the glue application work can be carried out. When the positioning rod 33 is pulled out of the positioning hole, the bracket can be swung open, thereby facilitating the removal and placement of the double-column capacitor bushing.
