Description

Technical Field

[0001] The utility model belongs to the technical field of copper bar processing, and specifically relates to a clamping component and a bending component. Background Art

[0002] Copper busbars are sheet-shaped workpieces made of copper with excellent electrical conductivity, heat dissipation and ductility. They are widely used in the field of electrical transmission. In practical applications, due to the limited space for installing copper busbars, in order to enable smooth installation, the copper busbars need to be bent accordingly.

[0003] During the bending process, the copper bar is first clamped by the clamping structure, and then bent by the bending structure. The clamping mechanism clamps the copper bar during processing to prevent it from tilting or shaking, so as to ensure the processing quality of the copper bar.

[0004] At present, compressed air is a common energy source that is relatively easy to obtain and can conveniently drive various mechanical equipment. Therefore, most of the clamping mechanisms for copper bars in the prior art are pneumatically driven. However, pneumatic drive has the following shortcomings in driving the clamping structure: the response speed of the pneumatically driven clamping device is relatively slow, and the air pressure is compressible, which will cause uneven driving speed, thereby affecting the stability of the copper bar clamping. Utility Model Content

[0005] The utility model aims to provide a clamping assembly which can improve the accuracy and stability of clamping a copper busbar.

[0006] The purpose of the utility model is achieved through such a technical solution, a clamping assembly, including: a working frame and a clamping mechanism, the clamping mechanism is installed on the working frame, and the clamping mechanism includes:

[0007] Servo electric push rod, installed on the working frame;

[0008] Two sets of clamping plates are arranged in mirror image, and a clamping space is formed between the clamping plates. The two sets of clamping plates are respectively installed at the output ends of the servo electric push rod;

[0009] The fixed plate is fixedly mounted on the working frame, the clamping plate is slidably connected to the fixed plate, and the sliding contact surfaces of the two are planes inclined relative to the horizontal plane; the bending structure is mounted on the fixed plate;

[0010] The servo electric push rod drives the clamping plate to move along the fixed plate, changing the size of the clamping space, thereby clamping or loosening the copper busbar.

[0011] The clamping assembly in the utility model transfers the copper bar to be processed to the clamping space, starts the servo electric push rod, the output end of the servo electric push rod retracts, and the two groups of clamping plates slide synchronously along the corresponding fixed plates. Under the cooperation of the inclined wedge surface of the clamping plate and the inclined wedge surface of the fixed plate, the clamping space between the two groups of clamping plates gradually becomes smaller until the copper bar is clamped between the clamping plates. If the output end of the servo electric push rod extends forward, the clamping space between the two groups of clamping plates gradually becomes larger, and the copper bar is released. The servo electric push rod is used to move the clamping plate at a uniform and stable speed, with a fast response speed and accurate positioning. The response speed of the pneumatically driven clamping assembly is relatively slow, and because the gas is compressible, the speed stability of the pneumatically driven clamping assembly is poor, and it cannot be used for accurate positioning. The motor is not affected by the ambient temperature and works stably. By adjusting the motor parameters, the clamping force of copper bars of different thicknesses can be adjusted, and the copper bars can be clamped more accurately.

[0012] Preferably, a sliding groove is provided on the edge of the upper surface of the fixing plate, and the clamping plate is provided with a sliding platform matching the sliding groove, and the sliding platform is embedded in the sliding groove and slides along the sliding groove.

[0013] Preferably, the slide groove type is one of a V-shaped groove, a U-shaped groove or a dovetail groove, and the shape of the slide table matches the slide groove.

[0014] Preferably, the clamping assembly further comprises a connecting rod, and the output end of the servo electric push rod is provided with two groups of grooves at intervals, one end of the connecting rod is installed in the groove, and the other end of the connecting rod is connected to the clamping plate.

[0015] Preferably, the fixed plate includes a fixed seat and an inclined wedge plate, one end of the fixed seat is fixedly mounted on the working frame; the inclined wedge plate is installed at intervals on the other end surface of the fixed seat, the upper surface of the inclined wedge plate is arc-shaped, and the lower surface is an inclined surface; the clamping plate is slidably installed on the inclined wedge plate, the upper surface of the clamping plate is consistent with the lower surface of the inclined wedge plate, and the lower surface of the clamping plate is a clamping plane.

[0016] Another object of the utility model is to provide a bending assembly, which can cooperate with the clamping assembly to bend the copper busbar.

[0017] Through such a technical solution, the bending assembly includes a bending structure, which is installed in a clamping mechanism. The bending structure rotates around the clamping mechanism to bend the copper busbar. The bending structure includes a bending plate and a rotary drive reducer; the rotary drive reducer is fixedly installed in the clamping mechanism, the bending plate is installed on the rotary drive reducer, and the bending plate rotates around the clamping mechanism.

[0019] The technical solution of the clamping assembly has the following advantages: a servo electric push rod is used as the power for clamping, and two sets of clamping plates are driven by the servo electric push rod. The two sets of clamping plates move synchronously relative to or opposite to each other according to the inclined wedge surface, so that the copper busbar is accurately and stably clamped between the two sets of clamping plates.

DETAILED DESCRIPTION

[0030] See also Figure 1 , Figure 2 , Figure 3 and Figure 4A clamping assembly includes: a working frame 31 and a clamping mechanism 32, the clamping mechanism 32 is installed on the working frame 31, and the clamping mechanism 32 includes: a servo electric push rod 321, which is installed on the working frame 31; two groups of clamping plates 322 arranged in mirror image, and a clamping space 323 is formed between the clamping plates 322, and the clamping plates 322 are installed at the output end of the servo electric push rod 321; a fixed plate 324 is fixedly installed on the working frame 31, the clamping plate 322 is slidably connected with the fixed plate 324, and the sliding contact surfaces of the two are planes inclined relative to the horizontal plane, and the bending structure 33 is installed on the fixed plate 324. The servo electric push rod 321 drives the clamping plate 322 to move along the fixed plate 324, changes the size of the clamping space 323, and thus clamps or releases the copper busbar. Specifically, the working frame 31 is installed on the production line. Taking the upper group of clamping plates 322 as an example, the plane inclined relative to the horizontal plane is gradually inclined from the outer end surface of the clamping plate 322 to the end surface close to the working frame 31, that is, an inclined wedge surface is formed, and the upper and lower clamping plates 322 are mirror-set. The fixed plate 324 corresponding to the upper group of clamping plates 322 is gradually inclined from the end surface of the fixed plate 324 close to the working frame 31 to the outer end surface of the fixed plate 324. Since the upper and lower groups of inclined wedge surfaces are mirror images, the movement of the two groups of clamping plates 322 is synchronous. By using the cooperation of the inclined wedge surfaces, the two groups of clamping plates 322 move relative to or away from each other, so that the clamping space 323 of the two groups of clamping plates 322 becomes smaller or larger, thereby achieving the clamping or loosening of the copper busbar.

[0031] The clamping assembly in the utility model transfers the copper bar to be processed to the clamping space 323 between the clamping plates 322, starts the servo electric push rod 321, the output end of the servo electric push rod 321 retracts, and the two groups of clamping plates 322 slide synchronously along the corresponding fixed plates 324. The wedge surface of the clamping plate 322 cooperates with the wedge surface of the fixed plate 324, and the clamping space 323 gradually becomes smaller until the copper bar is clamped between the clamping plates 322. If the output end of the servo electric push rod 321 extends forward, the space between the clamping plates 322 gradually becomes larger, the copper bar is taken out, and the next copper bar is processed. The servo electric push rod 321 is used to move the clamping plate 322 at a steady speed, and can be accurately positioned. The motor operation is not affected by the ambient temperature and the operation is stable. The response speed of the pneumatic drive device is relatively slow, and it cannot be used for precise positioning. In addition, due to the compressibility of the gas, the stability of the pneumatic working speed is poor. By adjusting the parameters of the servo electric push rod 321, the clamping force of copper bars of different thicknesses can be adjusted to reduce the clamping marks when the copper bars are clamped. Therefore, compared with pneumatic clamping, the servo electric push rod 321 drive has greater stability and greatly improved accuracy, and the clamping force adjustment is more flexible and more convenient to adjust.

Specifically, the inner wall of each group of grooves 3211 is a plane, and the gap between the inner walls matches the thickness of the connecting rod 325. The connecting rod 325 is installed on the inner wall of the plane, and the installation area is increased. The servo electric push rod 321 pulls the connecting rod 325 more smoothly.
