Description

Technical Field

[0001] The invention relates to the technical field of automatic damping strip sticking, and in particular to a damping strip clamping device. Technical Background

[0002] The generator damping winding is mainly used to prevent the generator from being impacted by a sudden load change. When the load of the generator changes, the voltage and current in its winding will form an oscillation process. The damping strip can increase the resistance to the oscillation process, forming a damped oscillation, thereby forming a certain buffering effect.

[0003] The damping strips also need to be pasted on the carbon brush holder of the motor. The current method of pasting the damping strips is generally to manually remove the damping strips from the damping strip sheet one by one, and then paste them manually; the existing carbon brush holder damping strip pasting equipment on the market can only be used for rolled damping strips, and the damping strips used on the carbon brush holder are in the form of plates before pasting. In order to be suitable for automatic damping strip pasting equipment, it is necessary to process the damping strips several times to make them into rolls, which invisibly increases the cost of raw materials. In addition, the damping strips on the sheet are connected. When the damping strips are taken out manually or by existing equipment individually, they will stick to other damping strips, which takes time to separate, resulting in low production efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a damping strip clamping device. The technical solution provided by the present invention solves the problem that manual operation or existing equipment cannot individually remove the plate-shaped damping strips from the damping strip sheet.

[0023] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment 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.

[0024] Example 1

[0025] like Figure 1 As shown, in order to solve the technical problem that the above-mentioned manual operation or existing equipment cannot individually remove the plate-shaped damping strips from the damping strip sheet, the present embodiment provides a damping strip clamping device, including a fixed table 100 for fixing the damping strip sheet, and a material picking mechanism 300 for clamping the damping strip on the sheet. The material picking mechanism 300 is arranged on a two-axis transmission mechanism 200, and the two-axis transmission mechanism 200 drives the material picking mechanism 300 to move to any position above the fixed table 100, so as to clamp any damping strip on the fixed table 100.

[0026] See also Figure 6The damping strip sheet is placed on a fixed platform 100. Clamping plates 110 for fixing the damping strip sheet are provided on both sides of the fixed platform 100. Edge pressing blocks 111 for pressing the damping strip sheet are extended on the opposite sides of the two clamping plates 110. The interior of the fixed platform 100 is hollow. A driving cylinder 120 for driving the clamping plates 110 is provided inside the fixed platform 100. Under the action of the driving cylinder 120, the clamping plates 110 are pressed down, and then the edge pressing blocks 111 are used to clamp the damping strip sheet.

[0027] In order to clamp the plate-shaped damping strip, the material picking mechanism 300 includes a clamping assembly 310 slidably disposed on the three-axis transmission mechanism 200. The clamping assembly 310 can be pressed down against the damping strip to be clamped and complete the clamping action.

[0028] For details, see Figure 2-3 The clamping assembly 310 includes a connecting plate 311 and a clamp fixed to the lower end of the connecting plate 311. A moving assembly 340 is provided on the three-axis transmission mechanism 200 to drive the clamping assembly 310 to move vertically. The moving assembly 340 is a moving cylinder 340. The moving cylinder 340 drives the connecting plate 311 to slide up and down, thereby enabling the clamping assembly 310 to move downward to abut against the damping strip to be clamped on the sheet material.

[0029] Furthermore, the clamp includes a clamping block 312 and two pins 314 arranged in the clamping block 312 and extending from the bottom of the clamping block 312. The clamping block 312 is fixed to the lower end of the connecting plate 311. The shape of the bottom of the clamping block 312 matches the damping strip, so that the clamping block 312 can abut against the plate-shaped damping strip to be clamped. Two slidable pins 314 arranged at an acute angle are arranged inside the clamping block 312. The two pins 314 form an angle of 70° and can extend toward the bottom of the clamping block 312. After the two pins 314 are extended, they intersect at the same horizontal position of the pressure strip 321. The clamping block 312 first abuts against the plate-shaped damping strip to be clamped, and then the pins 314 extend out and insert into the plate-shaped damping strip to be clamped, thereby finally achieving the purpose of clamping the plate-shaped damping strip.

[0030] In order to extend the pin 314 out of the bottom of the clamping block 312 to insert and clamp the damping strip, a pressure block assembly that can press down to drive the clamping block 312 to clamp the damping strip is provided above the clamping block 312, and the pressure block assembly is arranged on the connecting plate 311. The pressure block assembly includes a pressure block 313 for extending the pin 314 to insert the damping strip to be clamped, and a pushing assembly 316 for driving the pressure block 313. The pushing assembly 316 is a driving cylinder, which is fixed on the connecting plate 311. A connecting block is fixed on the telescopic end of the driving cylinder, and both sides of the connecting block are respectively fixed to the pressure block 313 to realize the lifting and pressing down of the driving pressure block 313.

[0031] For further information, see Figure 4-5The clamping block 312 is provided with a first sliding groove 318 penetrating along the sliding direction of the pin 314, and a second sliding groove 319 penetrating therethrough is horizontally formed on the pressing block 313. The sliding groove 318 penetrates the clamping block 312 and exposes the pin 314. A pin shaft 315 linked to the pin 314 is inserted in both sliding grooves. The pin 314 and the pin shaft 315 are arranged in linkage. The pressing block 313 is pressed down by driving the cylinder 316, thereby driving the pin shaft 315 to slide downward along the two sliding grooves, thereby driving the pin 314 to extend and extend, and the plate-shaped damping strip is clamped by the pin 314.

[0032] When the material picking mechanism 300 clamps a single damping strip, since the damping strips on the sheet material are connected, the damping strips around it will stick when the damping strip is taken out. Therefore, in order to ensure that a single damping strip is taken out without sticking to other damping strips, the present embodiment also includes a pressure strip 321 arranged on the clamping assembly 310 and used to press the damping strips around the damping strip to be clamped.

[0033] Specifically, the pressure strip 321 is arranged on the connecting plate 311 and is staggered with the clamp in the horizontal direction. The bottom of the pressure strip 321 is formed with a supporting portion 322 extending to the bottom of the clamping block 312, and the supporting portion 322 is formed with a clamping window for the insertion pin 314 to extend into. The supporting portion 322 can press the damping strips around the damping strip to be clamped, and the clamping window exposes the damping strip to be clamped, so that the insertion pin 314 does not stick to the surrounding damping strips after clamping out the damping strip.

[0034] To summarize, a clamping assembly is arranged on the three-axis transmission mechanism, a clamping block that can rest against the plate-shaped damping strip is arranged on the clamping assembly, the clamping block is provided with an extendable pin, the pin is driven by the pressure block assembly to insert and clamp the plate-shaped damping strip, and the damping strips around the damping strip to be clamped are pressed by the pressure strip arranged on the clamping assembly, thereby achieving the purpose of clamping a single damping strip and improving the accuracy and efficiency of attaching the damping strip.

[0035] Example 2

[0036] The present embodiment provides a damping strip clamping device, which also includes a fixing table 100 for fixing the damping strip sheet material, a material picking mechanism 300 for clamping the damping strip on the sheet material, and a transmission mechanism 200 for driving the material picking mechanism 300. The material picking mechanism 300 includes a clamping assembly 310 that can be pressed down to clamp the damping strip and a pressure strip assembly 320 that can be pressed down to compact the damping strip. The clamping assembly 310 and the pressure strip assembly 320 are staggered in the horizontal direction.

[0037] The pressure strip 321 is arranged on the connecting plate 311 and is staggered with the clamp in the horizontal direction. The bottom of the pressure strip 321 is formed with a supporting portion 322 extending to the bottom of the clamping block 312. The supporting portion 322 is formed with a clamping window for the insertion pin 314 to extend into. The supporting portion 322 can press the damping strips around the damping strip to be clamped, and the clamping window exposes the damping strip to be clamped, so that the insertion pin 314 does not stick to the surrounding damping strips after clamping out the damping strip.

[0038] See also Figure 3 In order to ensure that the damping strip can be taken out individually without sticking to other damping strips, as a further improvement in technology, the present embodiment is different from the embodiment 1 in that a support plate 317 is fixed to the upper end of the connecting plate 311, and a pressing component 323 is fixed on the supporting plate 317 to drive the pressure strip 321 to move downward to press the damping strips around the damping strip to be clamped. The pressing component 323 is a pressing cylinder 323, and the telescopic end of the pressing cylinder 323 fixes the pressure strip 321. The pressure strip 321 is slidably arranged on the connecting plate 311 and is located on the other side of the clamping block 312. The damping strips around the damping strip to be clamped are pressed by the abutting portion 322 extending to the bottom of the clamping block 312, and the pressing effect of the damping strip is improved by driving the pressure strip 321 to press downward.

[0039] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
