[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-5As shown, the utility model is to solve the problem of low efficiency of back-hole processing using a drilling machine and a special fixture in the prior art. The following technical solutions are provided: an automatic back-hole processing device for a commutator, comprising a workbench 1, a processing support 2 is installed on the upper side of the workbench 1, a lifting seat 4 with an adjustable position is installed on the front side of the processing support 2, a back-hole processing component 3 is provided on the lifting seat 4, the back-hole processing component 3 includes a liftable rotating spindle 35 and a back-hole tool 36 located at the lower end of the rotating spindle 35, a processing platform 8 is installed on the workbench 1 in front of the processing support 2, a loading position 81 and a unloading position 82 are provided on the front side of the processing platform 8, a guide component 9 is provided on the processing platform 8 between the loading position 81 and the unloading position 82, the guide component 9 forms a guide groove, a pusher slider 10 is slidably provided in the guide groove, and a pusher slider corresponding to the loading position 81 is provided on the front side of the processing platform 8. The loading push block 14 is perpendicular to the slider 10, and the loading push block 14 is driven by the second cylinder 12 to translate and push the commutator on the loading position 81 into the guide groove. One end of the guide groove is a processing position corresponding to the back-hole tool 36. The pushing slider 10 is driven by the first cylinder 11 at one end thereof to slide and push the commutator to the processing position. A unloading push block 7 is provided on the upper side of the processing platform 8 and at the rear side of the processing position. The unloading push block 7 is pushed and translated by the third cylinder 6 on one side of the processing support 2 to push the commutator on the processing position to the unloading position 82. By setting the loading push block 14, the pushing slider 10 and the unloading push block 7 and combining them with the loading position 81 and the unloading position 82, the commutator can be automatically and accurately positioned after loading and automatically moved out after processing is completed, which greatly improves the efficiency of loading and unloading and meets the needs of automated production.

[0021] Specifically, the automatic back-hole processing device for the commutator in this embodiment can be used as a separate device or as part of a production line, placed together with equipment for other processing steps, and the commutator can be transferred between different processing steps through a robot.

[0022] In this embodiment, the robot is used to move the commutator of the previous process to the loading position 81, and the robot can also be used to clamp the commutator that has been back-hole processed on the unloading position 82 and transport it to the next process.

[0023] In this embodiment, positioning structures may or may not be provided on the loading position 81 and the unloading position 82. The loading position 81 and the unloading position 82 may be designed as portions protruding forward from the front side of the processing platform 8. The guide component 9 may be configured as two elongated guide blocks, with a guide groove formed between the two guide blocks. The width of the guide groove is consistent with the width of the corresponding commutator. The guide block farther from the loading position 81 is longer than the other guide block. In this way, the loading push block 14 pushes the commutator against the longer guide block, so that the material can be smoothly pushed into the guide groove by the push slider 10.

[0024] The first cylinder 11 can be set on the lower side of the processing platform 8. The extended rod of the first cylinder 11 is connected to the tail of the pusher slide 10 through a connecting block. The front end of the pusher slide 10 can be provided with an arc-shaped positioning groove, the size of which matches the commutator. A quarter-circular arc groove is provided on one side of the end of the blanking pusher block 7. When the commutator is positioned and processed, the arc groove on the blanking pusher block 7 and the arc-shaped positioning groove on the pusher slide 10 together clamp the commutator to prevent the commutator from moving horizontally. After the processing is completed, the pusher slide 10 retreats, and the blanking pusher block 7 can push the commutator forward through the arc groove to achieve blanking.

[0025] The second cylinder 12 can be set on one end surface of the processing platform 8, and the extension rod of the second cylinder 12 can also be connected to the loading push block 14 through a connecting block. The end of the loading push block 14 is also provided with an arc positioning groove.

[0026] In this embodiment, if Figure 2 and 4 As shown, a fourth cylinder 17 is installed on the front side of the processing support 2 below the lifting seat 4, and the extending rod of the fourth cylinder 17 is vertically downward to the pressure plate 5. A through hole 51 is provided on the pressure plate 5 at a position corresponding to the back-hole tool 36. When the commutator is processed, the commutator can be pressed by the pressure plate 5, and cooperated with the blanking push block 7 and the push slider 10 to realize all-round positioning and fixation of the commutator without the need to set up a separate positioning tool.

[0027] In this embodiment, if Figure 1-2As shown, a fifth cylinder 13 is vertically installed on the workbench 1 on the front side of the processing platform 8, and the extending rod of the fifth cylinder 13 is connected to the connecting plate 15 upward, and one end of the connecting plate 15 extends to the bottom of the loading position 81 and one end of the connecting plate 15 is connected to a positioning rod 16 that vertically passes through the processing platform 8. The commutator placed on the loading position 81 can be initially positioned by the positioning rod 16 to prevent the commutator from being misaligned with the loading push block 14, thereby improving the reliability of loading. When the commutator needs to be placed, the fifth cylinder 13 drives the positioning rod 16 to pass upward through the processing platform 8, and then the commutator can be sleeved on the positioning rod 16 for positioning. When the commutator needs to be pushed, the fifth cylinder 13 drives the positioning rod 16 to descend and disengage from the commutator, so that the loading push block 14 can push the commutator to move.

[0028] In this embodiment, the back-hole processing assembly 3 includes a lifting drive motor 31 installed on the top of the lifting seat 4. The main shaft of the drive motor 31 is connected to the screw rod 33 vertically arranged inside the lifting seat 4. The screw rod 33 is provided with a connecting nut 32. The connecting nut 32 is connected to the rotating spindle 35. The rotating spindle 35 is coaxially inserted with a drive spindle 34. The upper end of the drive spindle 34 is connected to the power motor 37 at the rear end of the lifting seat 4. The lifting drive motor 31 can achieve precise lifting and lowering of the rotating spindle 35. The overall structure is compact and reasonable. The drive spindle 34 and the rotating spindle 35 are coaxially arranged. The two can move axially relative to each other, but will not move circumferentially relative to each other. Therefore, when the drive spindle 34 rotates, it can drive the rotating spindle 35 to rotate synchronously, and when the rotating spindle 35 is lifted or lowered, the drive spindle 34 will not lift or lower.

[0029] In this embodiment, if Figure 4 As shown, a transverse plate 18 is provided at the lower end of the processing support 2, and a transverse support seat 19 is provided on the lower side of the transverse plate 18. The transverse plate 18 and the transverse support seat 19 are slidably connected by a slide rail, and the left and right positions of the processing support 2 can be adjusted to adapt to different processing conditions.

[0030] In this embodiment, if Figure 4 As shown, an air-avoidance hole 21 is opened on the processing platform 8 at a position corresponding to the processing position, and a debris collection guide column 20 is installed on the lower side of the processing platform 8 at a position corresponding to the air-avoidance hole 21, which can collect the debris generated during the back-hole process, and the debris will not fall on the processing platform 8 and the workbench 1, reducing the frequency of cleaning the processing platform 8 and the workbench 1. A debris collection frame can be set under the workbench 1, and the debris collection guide column 20 can pass through the workbench 1 and collect the debris from the corresponding debris collection frame.
