[0035] Embodiment 1
[0036] Please refer to Figures 1-7 As shown in the drawings, a pull broach forming type rotating shaft production equipment, including the base 1, the rear end middle part of the upper surface of the base 1 is throughly provided with a guide groove 101, the front end middle part of the inner surface of the guide groove 101 is movably installed with a guide screw 102 through a bearing, the other end of the guide screw 102 extends out of the rear end middle part of the guide groove 101, the rear end of the base 1 is fixedly installed with a first motor 7, the output end of the first motor 7 is fixedly connected with the end part of the guide screw 102 extending out, the outer surface of the guide screw 102 is spirally installed with a workbench 2, the rear end middle part of the upper surface of the base 1 is fixedly installed with a guide rail 103 on both sides, the lower surface of the workbench 2 is movably installed on the outer surface of the guide rail 103;
[0037] It should be noted that the first motor 7 controls the guide screw 102 to rotate clockwise, so as to push the workbench 2 to move horizontally along the guide groove 101, and the guide groove 101 cooperates with the guide rail 103 to limit the workbench 2 during the movement process, so as to ensure the accuracy of the horizontal movement of the workbench 2;
[0038] The first motor 7 controls the guide screw 102 to rotate clockwise, which is set to an indirect state, the number of turns of the single rotation of the transmission shaft of the first motor 7 is set, the number of turns of the single rotation controls the distance of the single horizontal movement of the workbench 2 driven by the guide screw 102, which needs to be matched with the length size of the pull broach head 1201, and the time interval of the operation of the first motor 7 is set, so as to ensure that the first motor 7 starts to control the guide screw 102 to drive the workbench 2 to move towards the direction of the pull broach head 1201 when the pull broach head 1201 is finished from the rotating shaft body 3.
[0039] The middle part of the upper surface of the workbench 2 is fixedly provided with a fixed frame 201 at both ends. Limiting grooves 202 are formed in the outer surface of the fixed frame 201. An adjusting screw 203 is spirally inserted and arranged on the upper surface of the fixed frame 201. A locking ring 204 is movably arranged on the output end of the adjusting screw 203 through a bearing. The locking ring 204 comprises two groups of semi-arc-shaped locking pieces. Locking ears 205 are protrusively arranged on the outer surface of the locking ring 204. The locking ears 205 extend outward through the limiting grooves 202. Locking bolts 206 are spirally inserted and arranged on the upper surface of the locking ears 205 away from the locking ring 204. A rotating shaft body 3 is clamped and fixed on the inner surface of the locking ring 204.
[0040] It should be noted that the fixed frame 201 is used as a support. The locking ring 204 can be controlled to vertically move along the fixed frame 201 by rotating the adjusting screw 203 clockwise or counterclockwise. The locking ears 205 arranged on the locking ring 204 can be inserted through the limiting grooves 202. The locking ears 205 can be used in cooperation with the limiting grooves 202 to limit the vertical movement of the locking ring 204, thereby avoiding deviation of the locking ring 204 during movement.
[0041] The rotating shaft body 3 is inserted into the locking ring 204. The locking ears 205 can be locked by the locking bolts 206. The rotating shaft body 3 can be locked in this way. In this case, the locking ring 204 can be controlled to vertically move by the adjusting screw 203, thereby indirectly driving the rotating shaft body 3 to adjust the position of the rotating shaft body 3 in the fixed frame 201, ensuring that the center point of the end of the rotating shaft body 3 is aligned with the broach head 1201.
[0042] The outer surface of the rotating shaft body 3 is fixedly provided with a fixed ring 4 at both ends. The fixed ring 4 comprises two groups of semi-arc-shaped fixed pieces. Fixed ears 401 are protrusively arranged on the outer surface of the fixed ring 4. Fixed bolts 402 are spirally inserted and arranged on the upper surface of the fixed ears 401 away from the fixed ring 4. A protective ring 5 is fixedly arranged at the front end of the outer surface of one of the fixed rings 4. The inner surface of the protective ring 5 is hollowly provided with an integrated net 501. The end of the integrated net 501 away from the fixed ring 4 is funnel-shaped with a front wide and a rear narrow. The front end of the protective ring 5 and the front end of the integrated net 501 are both truncated. The protective ring 5 and the integrated net 501 are both fixedly provided with an elastic band 502.
[0043] It should be noted that the fixed ring 4 is sleeved on the outer surface of the two ends of the shaft body 3, and the fixed lug 401 is locked by the fixed bolt 402 to complete the fixed connection between the fixed ring 4 and the shaft body 3. The protective ring 5 arranged on the fixed ring 4 at the front end of the shaft body 3 is close to the broach head 1201, and the debris discharged from the hole in the shaft body 3 is discharged from the hole close to the broach head 1201.
[0044] The integrated net 501 arranged in the protective ring 5 can intercept and collect the debris discharged from the shaft body 3. When the integrated net 501 is arranged in a front wide and rear narrow style away from the fixed ring 4, the port of the protective ring 5 away from the fixed ring 4 is in a contracted state, so as to further intercept the debris and prevent the debris from splashing.
[0045] Another fixed ring 4 is fixedly installed on the outer surface of the rear end of the shaft body 3. The other end of the connecting rod 6 is fixedly installed with a clamp 601, and the clamp 601 is arranged in alignment with the center point of the rear end of the shaft body 3. The lower surface of the clamp 601 is spirally penetrated and installed with a positioning pin 602. The rear end of the base 1 is fixedly installed with an air pump 8. The output end of the air pump 8 is fixedly provided with a gas conveying pipe 801, and the other end of the gas conveying pipe 801 is inserted and installed into the clamp 601.
[0046] It should be noted that the connecting rod 6 supports and fixes the clamp 601 to ensure that the clamp 601 is aligned with the center point of the rear end of the shaft body 3. At this time, the end of the gas conveying pipe 801 away from the air pump 8 is inserted into the clamp 601 and locked by the positioning pin 602, so as to complete the alignment and fixation of the gas conveying pipe 801 relative to the center point of the rear end of the shaft body 3. At this time, the air pump 8 is started to generate high-pressure gas flow and inject it into the rear end center point of the shaft body 3 through the gas conveying pipe 801.
[0047] Since the shaft body 3 needs to be first penetrated to form a communication hole before using the broach head 1201 to form a hole by broaching, the high-pressure gas flow can be injected into the communication hole and discharged from the other end through the communication hole. At this time, the high-pressure gas flow discharged can carry the debris generated by the broaching of the shaft body 3 and inject it into the protective ring 5.
[0048] The first motor 7 and the air pump 8 are fixedly installed with an assembly frame 104 on the outer surface of the air pump 8. The assembly frame 104 is fixedly connected with the rear end of the lower surface of the base 1.

[0051] It should be noted that the cutting fluid can be stored in the storage box 105, the liquid pump 1003 is started to cooperate with the flow guide pipe 1002 to extract the cutting fluid in the storage box 105 into the shunt pipe 10, and the cutting fluid is sprayed out through the plurality of nozzles 1001, since the nozzles 1001 and the broach head 1201 are arranged in the same plane, the cutting fluid sprayed out through the nozzles 1001 can be used to flush the broach head 1201, so that the effect of cleaning the debris in the groove of the broach head 1201 is achieved, and the broach head 1201 is cooled to ensure the broaching state;
[0052] The flushed cutting fluid can carry the debris to fall on the filter screen 901 through the opening formed in the upper surface of the base 1, and re-enter the storage box 105 after being filtered by the filter screen 901 and the filter cotton block 902, so that the effect of recycling is achieved, and the cutting fluid can be discharged through the drain hole by opening the plug screw cap 106 arranged at the bottom of the storage box 105 after being used for several times.
[0053] The front end of the upper surface of the base 1 is fixedly installed with a support frame 11, the rear end of the outer surface of the support frame 11 is formed with an adjusting groove 1101, the outer surface of the adjusting groove 1101 is movably and sleevedly installed with an adjusting block 1102, the lower surface of the adjusting block 1102 is fixedly installed with a gripper 1103, the inner surface of the gripper 1103 is inserted and fixedly installed with a broach rod 12, and the rear end of the broach rod 12 is fixedly provided with a broach head 1201;
[0054] The middle part of one side of the outer surface of the adjusting block 1102 is fixedly provided with a first connecting shaft 1104, the other side of the front end of the supporting frame 11 is fixedly installed with a second motor 1105, the front ends of the outer surfaces of both sides of the supporting frame 11 are jointly and movably installed with control rings 13, the middle parts of the sides close to each other of the outer surfaces of the control rings 13 are jointly and penetratively provided with a supporting shaft through the supporting frame 11, the outer surface of the middle part of one side of one of the control rings 13 is fixedly connected with the output end of the second motor 1105, the outer surface of the front end of the other control ring 13 is fixedly provided with a second connecting shaft 1301, and the second connecting shaft 1301 and the outer surface of the first connecting shaft 1104 are jointly and movably provided with a control rod 1302.
[0055] It should be noted that the length dimension of the broach rod 12 and the broach head 1201 exposed from the clamping device 1103 needs to match the length dimension of the shaft body 3 by inserting the broach rod 12 into the clamping device 1103 and locking, at this time, the second motor 1105 can be started to control the control ring 13 to rotate clockwise, and since the second connecting shaft 1301 provided on the control ring 13 is eccentrically arranged, the control ring 13 can drive the control rod 1302 to move horizontally when the control ring 13 rotates clockwise.
[0056] When the control ring 13 drives the second connecting shaft 1301 to rotate to the rear end, the control rod 1302 can be extended towards the rear end, at this time, the first connecting shaft 1104 connected to the other end of the control rod 1302 can be pushed by the extension of the control rod 1302, thereby indirectly pushing the adjusting block 1102 to move horizontally rearward along the adjusting groove 1101, at this time, the broach head 1201 can be controlled to move rearward and contact the center point of the front end of the shaft body 3 by the rearward movement of the adjusting block 1102, and the broach head 1201 can be continuously moved rearward by the continuous rotation of the control ring 13, thereby driving the broach head 1201 to extend into the shaft body 3 for broaching a hole.
[0057] When the control ring 13 drives the second connecting shaft 1301 to rotate to the front end by continuous rotation, the control rod 1302 can be extended towards the front end, at this time, the first connecting shaft 1104 connected to the other end of the control rod 1302 can be pulled by the control rod 1302, thereby indirectly pulling the adjusting block 1102 to move horizontally forward along the adjusting groove 1101, at this time, the broach head 1201 can be controlled to move forward and be separated from the shaft body 3 by the forward movement of the adjusting block 1102, and a single broaching is completed.
[0058] In use, first, the through holes are formed in the center of the two ends of the rotating shaft body 3, and the rotating shaft body 3 is fixed in the locking ring 204, at this time, the locking ring 204 drives the rotating shaft body 3 to vertically ascend by rotating the adjusting screw 203 clockwise, until the front end center of the rotating shaft body 3 is aligned with the broach head 1201, at this time, the first motor 7 is started to control the guide screw 102 to rotate clockwise according to the set single running circle, so as to control the workbench 2 to drive the rotating shaft body 3 to move forward, the single forward moving distance is equal to the length of the broach head 1201, when the rotating shaft body 3 reaches the specified position, the second motor 1105 is started to control the control ring 13 to rotate clockwise;
[0059] When the control ring 13 rotates clockwise, the second connecting shaft 1301 is first rotated towards the rear end of the workbench 2, in the rotating process, the second connecting shaft 1301 pushes the control rod 1302 to extend towards the rear end, at this time, the first connecting shaft 1104 connected to the other end of the control rod 1302 is pushed by the extension of the control rod 1302, so as to indirectly push the adjusting block 1102 to move laterally rearward along the adjusting groove 1101, at this time, the broach head 1201 is controlled to move rearward to contact the center point of the front end of the rotating shaft body 3 by the rearward movement of the adjusting block 1102, and the adjusting block 1102 continuously moves rearward with the continuous rotation of the control ring 13, so as to drive the broach head 1201 to extend into the rotating shaft body 3 for broaching;
[0060] Secondly, when the control ring 13 continuously rotates to drive the second connecting shaft 1301 to rotate away from the front end of the workbench 2, the control rod 1302 is driven to extend towards the front end, at this time, the first connecting shaft 1104 connected to the other end of the control rod 1302 is pulled by the control rod 1302, so as to indirectly pull the adjusting block 1102 to move laterally forward along the adjusting groove 1101, at this time, the broach head 1201 is controlled to move forward to separate from the rotating shaft body 3 by the forward movement of the adjusting block 1102, and the single broaching is completed;
