As shown in fig. 1 to 5, the roller lifting mechanism of the bus arc double-station machining center includes a machine body 1, milling machines 2 located on two sides of the machine body 1, and a roller lifting assembly 3 located between the two milling machines 2, wherein each milling machine 2 includes a clamping mechanism 21, a machine head 22, and a milling cutter 23 located on the machine head 22, and the clamping mechanism 21 is used for clamping a copper bar so that the milling cutter 23 can mill the copper bar. The roller lifting assembly 3 comprises a bracket 31, rollers 32 uniformly distributed on the bracket 31 along the extending direction of the bracket 31, a chain wheel 34 connected with the rollers 32 through a chain 33, a motor 35 driving the chain wheel 34 to rotate, and an air cylinder 36 positioned at the bottom of the bracket 31, wherein the axis of the roller 32 is perpendicular to the extending direction of the bracket 31, and the air cylinder 36 can push the bracket 31 to move up and down. The roller lifting assembly 3 is used for conveying the copper bar in a lifting state; when the decline state, can prevent that gyro wheel lifting unit 3 from restricting milling machine 2 from to the scope of milling of copper bar.

In one embodiment, the copper bar is conveyed to the roller lifting assembly 3 by conveying equipment of the bus arc double-station machining center, and the roller lifting assembly 3 further conveys the copper bar. After the copper bar is conveyed to the position to be processed through the roller 32 of the roller lifting component 3, the clamping mechanism 21 of the milling machine 2 clamps and fixes the busbar, then the cylinder 36 drives the support 31 to move downwards so as to separate the support 31 from the copper bar, and the copper bar is clamped and fixed by the clamping mechanisms 21 at the two ends. The head 22 of the milling machine 2 moves to make the milling cutter 23 process the copper bar. Milling machine 2 does not receive the restriction of gyro wheel lifting unit 3 to the trace of milling of copper bar, therefore milling machine 2 can carry out milling process to the whole copper bar that is located between two milling machines 2, improves milling machine 2 and to female processing range who arranges. After the milling machine 2 finishes milling the copper bar, the air cylinder 36 pushes the support 31 to move upwards so that the roller 32 on the support 31 supports the processed copper bar, the clamp mechanism 21 releases the clamping of the copper bar, and the motor 35 drives the roller 32 to rotate through the chain wheel 34 and the chain 33 so as to convey the copper bar.

It should be noted that, among the prior art, the state that gyro wheel 32 conveying mechanism between two milling machines 2 is not liftable, and milling machine 2 mills the copper bar with man-hour, receives gyro wheel 32 conveying mechanism's restriction, and milling cutter 23 bumps with gyro wheel 32 conveying mechanism very easily, and consequently gyro wheel 32 conveying mechanism has restricted milling cutter 23 to the orbit that mills of copper bar, and then makes milling machine 2 receive the restriction to the machining dimension of copper bar, is unfavorable for milling cutter 23 to process whole copper bar. And this application adopts gyro wheel lifting unit 3, and when milling machine 2 milled the copper bar and adds man-hour, gyro wheel lifting unit 3 moved down in order not to hinder milling cutter 23's the orbit that mills, consequently made milling machine 2 to carry out milling process to whole copper bar.

Preferably, the limiting assembly 37 is disposed on two sides of the bracket 31, the limiting assembly 37 includes a plurality of limiting modules 38, and each limiting module 38 includes a supporting block 381 fixed to the bracket 31 and a vertically disposed limiting wheel 382 mounted on the supporting block 381. The limiting module 38 can prevent the copper bar from breaking away from the bracket 31 along the axial direction of the roller 32, and the limiting wheel 382 can reduce the resistance received when the copper bar moves on the roller lifting component 3.

In an embodiment, when roller lifting assembly 3 carried the copper bar, the copper bar caused the damage to the copper bar easily with the lateral wall friction collision of roller lifting assembly 3 very easily, and was unfavorable for the transport of gyro wheel 32 to the copper bar. Especially, when roller lifting unit 3 just contacted with the copper bar after rising, the copper bar often can with one of them lateral wall butt of roller lifting unit 3's support 31, be unfavorable for gyro wheel 32 to carry the copper bar. Therefore, the two sides of the bracket 31 are provided with the limiting assemblies 37, the copper bar is abutted against a plurality of limiting wheels 382 of the limiting assemblies 37, and the resistance of the copper bar during moving is reduced.

It should be noted that, in the prior art, the copper bar abuts against the side wall of the bracket 31, and the copper bar is rubbed by the side wall of the bracket 31 when moving, which is not beneficial to the movement of the copper bar on the bracket 31. And the limiting assemblies 37 are arranged on two sides of the support 31, and the copper bars are in sliding friction with the limiting assemblies 37 when moving, so that the resistance of the copper bars when moving is reduced. It also needs to explain that the width weak point of copper bar is in the distance between two spacing subassemblies 37, often when the copper bar removes with one of them spacing subassembly 37 butt.

Preferably, each supporting block 381 protrudes towards the inside of the bracket 31 to form two supporting protrusions 383, each supporting protrusion 383 is internally provided with a sliding groove 384, a bearing sliding block 385 is arranged in the sliding groove 384, and a spring 386 is connected between the bearing sliding block 385 and the side wall of the sliding groove 384, and a corresponding limiting wheel 382 is installed between the two bearing sliding blocks 385. The limiting wheel 382 is elastically connected to the supporting block 381, so that the copper bar is protected.

In one embodiment, when the copper bar moves on the roller 32, when the copper bar collides with the limiting wheel 382, the copper bar presses the limiting wheel 382 so that the bearing sliding blocks 385 at the two ends of the limiting wheel 382 slide along the sliding grooves 384 to press the springs 386, thereby preventing the copper bar from colliding with the limiting wheel 382 and being damaged. Wherein the outer shell of the bearing slider 385 is a square outer shell to enable sliding within the sliding groove 384. Spacing wheel 382 elastic connection helps realizing the protection to the copper bar to supporting shoe 381, prevents that the copper bar lateral wall from receiving the collision and damaging. It should be noted that the height distance of the limiting wheel 382 is greater than the thickness distance of the copper bar. The support protrusions 383 located below the support blocks 381 are lower than the top of the roller 32 to prevent the support protrusions 383 from contacting the copper bar.

Preferably, there are two sets of air cylinders 36, each air cylinder 36 includes a cylinder body 361 and an extension rod 362 moving up and down along the cylinder body 361, and the top of the extension rod 362 is fixedly connected with the bracket 31 through a connecting seat 363. The telescopic rod 362 moves along the cylinder 361 to realize the movement of the bracket 31 in the vertical direction, the telescopic rod 362 is connected with the bracket 31 through the connecting seat 363, and the stability of the connection between the telescopic rod 362 and the bracket 31 is improved.
