[0001] The utility model relates to a special device for pole column processing, and is particularly suitable for processing the pole column on the train braking mechanism. Through the synergistic effect of the moving mechanism and the processing mechanism, the device realizes the efficient and precise processing of one or two threaded holes on both end faces of the pole column. Background Art

[0002] The pole column on the train braking mechanism is an important part, and its processing accuracy has a direct impact on the safety performance of the train. At present, the processing of pole columns in the market mostly adopts traditional manual or single-machine processing methods, which have problems such as low processing efficiency and difficult accuracy guarantee.

[0003] The patent with the application number CN201910343856.1 provides an automatic pole column processing device, belonging to the field of mechanical technology. It solves the problem of poor stability existing in the prior art. This automatic pole column processing device is arranged on a lathe. The lathe has a chuck for clamping the pole column and a tool rest for installing tools, and includes a vibrating hopper, a discharge channel, a first manipulator and a second manipulator. The vibrating hopper is fixedly connected to the top of the lathe and the vibrating hopper is located above the chuck. The discharge channel is inclined and the upper end of the discharge channel is communicated with the vibrating hopper. The first manipulator and the second manipulator are both connected to the lathe. The first manipulator can clamp the pole column output from the lower end of the discharge channel at the chuck, and the second manipulator can take out the processed pole column from the chuck. This automatic pole column processing device has high stability.

[0004] However, the above patent technology still has problems such as low processing efficiency and difficult accuracy guarantee, that is, it does not solve the problems existing in the prior art and does not give relevant inspiration. Therefore, it has important practical significance to develop a special device for efficient and precise pole column processing. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a special device for pole column processing to solve the problems raised in the above background art:

[0006] (1) How to achieve the efficient and precise processing of the pole column through an integrated equipment layout and by using automated and mechanized means.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A special device for pole column processing;

[0009] It includes at least one set of moving mechanism and at least one set of processing mechanism, and the moving mechanism corresponds to the processing mechanism one by one;

[0010] The moving mechanism includes two sliding rails, a lead screw slide, an automatic chuck, and a driving motor. The two sliding rails are arranged in parallel. The two ends of the lead screw slide are respectively fitted with the sliding rails. The lead screw slide can reciprocate along the direction of the sliding rails. The sliding seat of the lead screw slide can reciprocate along the length direction of the lead screw slide. The moving trajectory of the sliding seat of the lead screw slide and the moving trajectory of the lead screw slide are perpendicular to each other in the horizontal plane projection. The driving motor is fixedly arranged on the sliding seat of the lead screw slide. The automatic chuck is connected to the output shaft of the driving motor and the driving motor drives the automatic chuck to rotate. The automatic chuck can hold the blank pole column and extend it outside the sliding seat of the lead screw slide.

[0011] The processing mechanism includes a side wall turning tool, an end face turning tool, a drilling power head, a chamfering power head, and a tapping power head. The side wall turning tool, the end face turning tool, the drilling power head, the chamfering power head, and the tapping power head are arranged beside the moving mechanism along the length direction of the lead screw slide.

[0012] On the basis of the above technical solution, the present utility model can also be improved as follows.

[0013] Further, the special device for pole column processing further includes a tool holder. The side wall turning tool, the end face turning tool, the drilling power head, the chamfering power head, and the tapping power head of the processing mechanism are sequentially fixedly connected to the tool holder.

[0014] Further, the special device for pole column processing includes two sets of moving mechanisms and two sets of processing mechanisms. The two sets of moving mechanisms and the two sets of processing mechanisms are symmetrically arranged along the length direction of the tool holder.

[0015] Further, the lead screw slide reciprocates along the direction of the sliding rail through a linear guide rail.

[0016] When adopting this structure, first, the blank pole column is held on the automatic chuck, and the driving motor drives the automatic chuck to rotate, so that the blank pole column rotates. Then, through the reciprocating movement of the sliding seat of the lead screw slide under the action of the lead screw motor, the blank pole column moves horizontally within the processing area of the processing mechanism. Next, according to the part to be processed, the corresponding processing tool (side wall turning tool, end face turning tool, drilling power head, chamfering power head or tapping power head) is selected for processing. After processing, through the cooperation of the lead screw slide and the automatic chuck, the processed pole column is removed, and a new blank pole column is held for the next round of processing.

At the same time, the device has a simple structure and convenient operation, and has a wide application prospect. Description of the Drawings

[0025] Please refer to Figures 1 to 2 as shown in

[0026] The special device for processing this terminal post includes a tool holder 100, two groups of moving mechanisms and two groups of processing mechanisms. The two groups of moving mechanisms and the two groups of processing mechanisms are symmetrically arranged along the length direction of the tool holder 100, and the two groups of moving mechanisms correspond to the two groups of processing mechanisms one by one.

[0027] The moving mechanism includes two sliding rails 210, a lead screw slide table 220, a chuck 230, and a driving motor 240. The two sliding rails 210 are arranged in parallel. The two ends of the lead screw slide table 220 are respectively engaged with the sliding rails 210, and the lead screw slide table 220 reciprocates along the direction of the sliding rails 210 through linear guides (in addition to linear guides, the lead screw slide table 220 can also reciprocate along the direction of the sliding rails 210 through a rack and pinion mechanism. Specifically, the rack and pinion mechanism includes a rack, a reduction motor, and a driving pinion. The rack is fixedly arranged on the lower side of one sliding rail 210, and the direction of the rack is the same as that of the sliding rail 210. The driving pinion is installed on the output shaft of the reduction motor, and the reduction motor is fixedly connected to the housing of the lead screw slide table 220. The driving pinion meshes with the rack. When the rack and pinion mechanism is started, it can drive the whole lead screw slide table 220 to reciprocate along the direction of the sliding rail 210).

[0028] The lead screw slide table 220 includes a lead screw motor, a sliding seat, and a lead screw. The sliding seat of the lead screw slide table 220 can reciprocate along the length direction of the lead screw slide table 220 under the action of the lead screw motor. The moving track of the sliding seat 221 of the lead screw slide table 220 is perpendicular to the projection of the moving track of the lead screw slide table 220 on the horizontal plane. The driving motor 240 is fixedly arranged on the sliding seat 221 of the lead screw slide table 220. The chuck 230 is connected to the output shaft of the driving motor 240, and the driving motor 240 drives the chuck 230 to rotate. The chuck 230 can hold the pole column blank and extend it outside the sliding seat 221 of the lead screw slide table 220;

[0029] The processing mechanism includes a side wall turning tool 310, an end face turning tool 320, a drilling power head 330, a chamfering power head 340, and a tapping power head 350. The side wall turning tool 310, the end face turning tool 320, the drilling power head 330, the chamfering power head 340, and the tapping power head 350 of the processing mechanism are sequentially fixed on the tool holder 100; The side wall turning tool 310, the end face turning tool 320, the drilling power head 330, the chamfering power head 340, and the tapping power head 350 are arranged beside the moving mechanism along the length direction of the lead screw slide table 220;

[0030] The side wall turning tool 310 can perform side wall processing on the pole column blank. The end face turning tool 320 can perform end face processing on the pole column blank. The drilling power head 330 can perform drilling operations on the end face of the pole column blank. The chamfering power head 340 can perform chamfering operations on the edge of the hole wall on the end face of the blank. The tapping power head 350 can perform tapping operations on the edge of the hole wall on the end face of the blank.

[0031] During processing, in the first step, when machining the side wall of the pole column blank, the lead screw slide 220 of the moving mechanism moves away from the tool holder 100 under the action of the rack and pinion mechanism. Then, the pole column blank is clamped on the automatic chuck 230, and the driving motor 240 is started to drive the pole column blank to rotate. The lead screw slide 220 drives the sliding seat to move, so that the pole column blank moves to a position close to the side wall turning tool 310 of the machining mechanism. Then, the linear guide drives the entire lead screw slide 220 to move closer to the tool holder 100. During this process, the side wall turning tool 310 cuts the side wall surface of the pole column blank. However, the above operation cannot cut the entire side wall of the pole column blank in one go, and the cutting of the outer wall of a partial area of the pole column blank is completed. Finally, the linear guide drives the entire lead screw slide 220 to move away from the tool holder 100 to retract the tool;

[0032] In the second step, when machining one end face of the pole column blank, the lead screw slide 220 drives the sliding seat to move, so that the pole column blank moves to a position close to the end face turning tool 320 of the machining mechanism. Then, the linear guide drives the entire lead screw slide 220 to move closer to the tool holder 100. During this process, the lead screw slide 220 drives the sliding seat to move radially along the pole column blank to achieve the cutting of the end face of the pole column blank, and the machining of one end face of the pole column blank is completed. Finally, the linear guide drives the entire lead screw slide 220 to move away from the tool holder 100 to retract the tool;

[0033] In the third step, when drilling the hole on one end face of the pole column blank, the lead screw slide 220 drives the sliding seat to move, so that the pole column blank moves to a position close to the drilling power head 330 of the machining mechanism. The linear guide drives the entire lead screw slide 220 to gradually move towards the drilling power head 330, and the drilling operation is carried out using the drilling power head 330, and then the tool is retracted;

[0034] In the fourth step, when tapping the hole on one end face of the pole column blank, the lead screw slide 220 drives the sliding seat to move, so that the pole column blank moves to a position close to the tapping power head 350 of the machining mechanism. The linear guide drives the entire lead screw slide 220 to gradually move towards the tapping power head 350, and the tapping operation is carried out using the tapping power head, and then the tool is retracted;

[0035] In the fifth step, when chamfering the hole on one end face of the pole column blank, the lead screw slide 220 drives the sliding seat to move, so that the pole column blank moves to a position close to the chamfering power head 340 of the machining mechanism. The chamfering power head 340 is used to carry out the chamfering operation, and then the tool is retracted;

[0036] After the above five steps, the machining of half of the pole column blank is completed. Then, the moving mechanism and machining mechanism on the other side are used to complete the machining of the other half of the pole column blank. The automatic chucks 230 of the two groups of moving mechanisms take over the pole column blank, and finally the overall machining of the pole column blank is completed.

[0037] The above is only one implementation mode of the present utility model. It should be pointed out that for those of ordinary skill in the art, several variations and improvements can be made without departing from the principle of the present utility model, and these should also be regarded as belonging to the protection scope of the present utility model.
