Detailed Description
In order that the invention may be more readily understood, a more particular description of the invention will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Example 1:
referring to fig. 1 to 10, the present embodiment provides a needle bearing cage splitting device, including: a workpiece 10 transfer unit adapted to transfer the workpiece 10 to be processed and output the processed workpiece 10; a workpiece 10 fixing unit adapted to perform fixed clamping of the workpiece 10 to be machined in an axial direction thereof; and a workpiece 10 sectioning unit adapted to section the workpiece 10 after the fixed clamping in the axial direction of the workpiece 10.
Specifically, the workpiece 10 transfer unit in the present embodiment includes a rotary table 1, at least two stations provided on the rotary table 1, and a driving mechanism connected to the rotary table 1 to drive the rotary table 1 to rotate. It should be noted that, when the rotary table 1 is provided with two stations, one station is used for placing the workpiece 10 to be processed, i.e. for realizing manual discharging, and the other station is used for splitting the processed workpiece 10, i.e. for realizing the feeding operation of the new workpiece 10 to be processed while splitting the processed workpiece 10, so that the processing efficiency can be improved. Of course, the rotary table 1 may be configured, for example, but not limited to, four, six, eight or ten stations, etc., so as to implement the systematic processing operation of different workpieces 10 by rotating the rotary table 1 at each small angle.
For the driving mechanism for driving the rotary table 1, a driving mechanism such as, but not limited to, a combination of a precision planetary reducer and a servo motor 19 is employed, that is, the position of the central axis of the rotary table 1 is connected to a rotary driving shaft which is connected to a servo motor 19 through the precision planetary reducer, so that the rotation of the rotary driving shaft is driven by the servo motor 19, thereby driving the rotation of the rotary table 1.
More specifically, the workpiece 10 sectioning unit includes a pair of sectioning mechanisms symmetrically disposed to symmetrically divide the workpiece 10 equally from both sides of the workpiece 10 along the axial direction of the workpiece 10, respectively. Here, the needle bearing cage (i.e., the workpiece 10 in the present embodiment) is generally split equally to achieve a symmetrical two-half structure of the needle bearing cage, and thus the present embodiment performs the equally split operation of the needle bearing cage along the axis of the needle bearing cage.
The cutting mechanism adopted in the embodiment comprises a blade 7 for cutting a workpiece 10, a cutter bar 6 fixedly connected with the blade 7, a cutter holder 5 fixedly connected with the cutter bar 6 for supporting the cutter bar 6, and a linear driving assembly connected with the cutter holder 5 and suitable for driving the cutter holders 5 of a pair of cutting mechanisms to move in opposite directions or in opposite directions. Alternatively, the linear drive assembly comprises a ball joint 4 connected to the tool holder 5, and a hydraulic cylinder 3 connected to the ball joint 4. The tool holder 5 is connected with the hydraulic cylinder 3 by the spherical joint 4, so that the force transmitted to the tool holder 5 by the hydraulic cylinder 3 is always consistent with the movement center height (H).
In order to define the path of travel of the tool holder 5, it is ensured here that the tool holder 5 is moved precisely in the direction of the workpiece 10 by the hydraulic cylinder 3, the tool holder 5 being mounted on a linear guide 2.
The blades 7 of the pair of slitting mechanisms are adapted to shear the workpiece 10 when the blades 5 of the pair of slitting mechanisms are moved towards each other. It should be noted that, the motion track of the hydraulic cylinders 3 included in the pair of splitting mechanisms can be independently adjusted, the principle of independent control of the hydraulic cylinders 3 at this time is shown in fig. 4, but when the splitting operation is performed, a synchronous valve is arranged between the hydraulic cylinders 3 included in the pair of splitting mechanisms to control the consistency of the actions of the two hydraulic cylinders 3, the principle of simultaneous control of the two hydraulic cylinders 3 is shown in fig. 5,
More specifically, the work 10 fixing unit includes a lower die mechanism adapted to support the bottom of the work 10 in the axial direction of the work 10 and an upper die mechanism adapted to abut against the top of the work 10 and to cover the side wall of the work 10.
The lower die mechanism comprises a workpiece seat 11 for supporting the workpiece 10, and a lower die driving assembly connected with the workpiece seat 11 and suitable for driving the workpiece seat 11 to move towards the upper die mechanism; the workpiece holder 11 is located at a station on the rotary table 1. The upper die mechanism comprises an upper die holder 13 which is suitable for being inserted into and filling the inner cavity of the workpiece 10, and a plurality of evenly distributed slots 21 which are arranged on the side wall of the upper die holder 13 and are suitable for the blades 7 to pass through, wherein the slots 21 on the upper die holder 13 correspond to the slots on the outer cylindrical surface of the workpiece 10. The outer diameter of the upper die holder 13 is designed to be suitable for being matched with the inner diameter of the inner cavity of the workpiece 10, so that the workpiece 10 can be smoothly sleeved on the outer periphery side of the upper die holder 13 when moving towards the upper die holder 13, the upper die holder 13 can avoid fixing the workpiece 10 due to the fact that the inner cavity of the workpiece 10 is filled, and the problem of shaking of the workpiece 10 in the cutting process is avoided. It should be noted that, in order to facilitate the cutting of the blade 7 thoroughly when the workpiece 10 is split, the blade 7 needs to be partially inserted into the slot 21 on the outer side wall of the upper die holder 13 after passing through the slot of the outer cylindrical surface of the workpiece 10, where the longitudinal height of the slot 21 is greater than the axial height of the workpiece 10, i.e. it is satisfied that the blade 7 passes completely through the slot 21. The slots 21 are optionally uniformly arranged into eight slots along the side wall of the upper die holder 13, and the eight slots 21 are uniformly distributed.
The specific principle of the axial fixing of the workpiece 10 in this embodiment is that a supporting effect is formed on the bottom of the workpiece 10 by the working seat, and then the supporting effect is formed on the side wall of the workpiece by the upper die holder 13, so that the whole workpiece 10 is fixed between the working seat and the upper die holder 13. In order to fix the workpiece 10 between the work seat and the upper die holder 13, the workpiece seat 11 and the upper die holder 13 in this embodiment are disposed in a forward direction, i.e., the workpiece seat 11 is located directly below the upper die holder 13. It should be noted that, in order to make the needle bearing cage splitting device of the present embodiment suitable for splitting workpieces 10 of different sizes, the upper die holder 13 is detachably assembled with the upper die holder fixing frame, for example, but not limited to, by an interference clamping or a threaded connection, so as to facilitate the replacement of the corresponding upper die holder 13 for workpieces 10 of different sizes.
The lower die driving assembly adopted in the embodiment comprises a spline shaft 12 fixedly connected with a workpiece seat 11 and a first driving cylinder 9 connected with the spline shaft 12 and suitable for driving the spline shaft 12 to move; the workpiece seat 11 is suitable for being mounted on a station seat, the station seat is fixedly connected with a station on the rotary workbench 1, the station seat is connected with the station of the rotary workbench 1 in a mode of, for example and without limitation, bolts, and the spline shaft 12 is fixedly connected with the workpiece seat 11 in a mode of, for example and without limitation, nuts 15. A spline hole suitable for the spline shaft 12 to pass through is penetrated in the station seat, so that the spline shaft 12 moves along the spline hole of the station seat under the action of the first driving cylinder 9 to realize the driving action on the workpiece seat 11. It should be noted that, in order to make the needle bearing cage splitting device of the present embodiment suitable for splitting workpieces 10 of different sizes, the workpiece seat 11 and the spline shaft 12 are connected by the nut 15, so that the disassembly is convenient, and the workpiece seat 11 of other sizes can be replaced, thereby improving the application range of the whole needle bearing cage splitting device.
Specifically, the workpiece holder 11 includes a bottom support portion 111 integrally connected to the spline shaft 12 and a support portion 112 connected to the bottom support portion 111 for supporting the workpiece 10; the side walls of the support 112 are symmetrically provided with a pair of pockets 20 adapted for the passage of the blades 7. Since the workpiece holder 11 supports the workpiece 10 from the bottom of the workpiece 10, the workpiece holder 11 needs to form a certain coating effect on the side wall of the workpiece 10 from the bottom of the workpiece 10 to the side wall of the workpiece 10, so that the workpiece 10 can be loaded in the workpiece holder 11 to realize a stable fixing effect, and in this case, in order to avoid the workpiece holder 11 from influencing the cutting of the workpiece 10 after coating the side wall of the workpiece 10, a pocket 20 suitable for the penetration of the blade 7 needs to be formed in the side wall of the supporting portion 112. Since the workpiece 10 needs to be split in half, a pair of symmetrically arranged pockets 20 are formed in the side wall of the support portion 112 of the workpiece holder 11 to accommodate the insertion of the pair of blades 7.
In order to prevent the workpiece 10 loaded in the workpiece seat 11 from influencing the accuracy of cutting due to the rotation problem during cutting, a positioning plate 16 is integrally arranged on the side wall of the supporting part 112; the locating piece 16 protrudes towards the top of the upper die holder 13 from the supporting part towards the top of the upper die holder 13; and the splines 16 are adapted to be partially inserted into one of the slots of the cylindrical sidewall of the workpiece 10. Namely, in the process of installing the needle bearing retainer in the workpiece seat 11, a notch on the cylindrical surface of the needle bearing retainer is clamped on the positioning sheet 16, so that the workpiece 10 is prevented from rotating in the workpiece seat 11 and the workpiece is prevented from being correctly machined; after the workpiece 10 is placed in the workpiece seat 11 according to the requirement, the workpiece 10, the spline shaft 12, the workpiece seat 11 and the positioning sheet 16 form a whole, and the synchronous movement process can be realized under the action of the first driving cylinder 9. When the piston rod of the first drive cylinder 9 protrudes toward the upper die holder 13, the workpiece 10 partially loaded on the workpiece holder 11 is pushed onto the upper die holder 13, so that the upper die holder 13 forms a supporting action for the workpiece 10 from the outer side wall of the workpiece 10.
Since the workpiece 10 is partially loaded in the workpiece holder 11, when the cutting is completed, the workpiece 10 can be moved down synchronously with the workpiece holder 11, i.e., in a direction away from the upper die holder 13, along with the retraction of the piston rod of the first driving cylinder 9, but since the upper die holder 13 also forms a supporting effect on the side wall of the workpiece 10, in order to avoid the resistance of the upper die holder 13 to the downward movement of the workpiece 10 and to accelerate the withdrawal of the workpiece 10 from the upper die holder 13, the needle bearing retainer split device of the present embodiment further includes a pushing unit adapted to push the workpiece 10 to be disengaged from the upper die holder 13.
Referring to fig. 11, specifically, the pushing unit includes a material returning member 14 adapted to be sleeved on the outer peripheral side of the upper die holder 13, and a second driving cylinder 18 connected to one end of the material returning member 14 and adapted to drive the material returning member 14 to move; the stripper member 14 is adapted to move along the outer side wall of the upper die holder 13. The material returning member 14 here comprises a first connecting part 141 integrally connected to the second driving cylinder 18 and a second connecting part 142 for being sleeved on the outer peripheral side of the upper die holder 13, and the second connecting part 142 is provided with a through hole 143 suitable for the upper die holder 13 to pass through.

When the first proximity switch 22 finds that the workpiece 10 is located on the station, the servo motor 19 rotates, so that the rotary table 1 rotates to drive the workpiece 10 on the station to reach the splitting position. The PLC sends out instructions to control the servo motor 19 to stop running, and the first driving air cylinder 9 starts to run, the first driving air cylinder 9 pushes up the spline shaft 12 part with the workpiece 10, the workpiece 10 to be split is arranged on the upper die holder 13, and the PLC sends out instructions to control the first driving air cylinder 9 to stop running when the first driving air cylinder 9 encounters the fifth proximity switch through an induction coil arranged on the first driving air cylinder 9 and a fifth proximity switch which is suitable for being connected with the induction coil in an induction mode. At this time, the PLC also simultaneously controls the two hydraulic cylinders 3 to simultaneously move in opposite directions, when the tool holder 5 moves to the fourth proximity switch for sensing the tool holder 5, representing that the split processing for the needle bearing retainer is finished, the PLC issues an instruction to control the two hydraulic cylinders 3 to simultaneously reset, and when the tool holder 5 moves to the third proximity switch for sensing the tool holder 5, the PLC issues an instruction to stop the movement of the tool holder 5. The first driving cylinder 9 is downward, the spline shaft 12 part with the workpiece 10 is downward under the action of gravity, and when the first driving cylinder 9 moves to the sixth proximity switch, the PLC system sends out a command, and the first driving cylinder 9 stops moving; at this time, synchronously, the second driving cylinder 18 moves downwards (i.e. towards the direction of the workpiece seat 11), the material returning part 14 is pushed to move downwards, so as to ensure that the workpiece 10 is separated from the upper die holder 13, when the second driving cylinder 18 to the seventh proximity switch, the PLC system sends out an instruction, the second driving cylinder 18 moves upwards (i.e. away from the direction of the workpiece seat 11), after the second driving cylinder 18 is in place, the eighth proximity switch on the second driving cylinder 18 sends out a signal, the PLC system sends out an instruction, the second driving cylinder 18 stops moving, the workbench rotates by an angle (station angle) under the driving of the servo motor 19, then if the workpiece 10 is arranged on the station according to the signal of the first proximity switch 22, the PLC repeats the instruction, and the split cutting work of the retainer is performed, and if the workpiece is not arranged, the servo motor 19 drives the workbench to rotate by a station … … again, and the cycle is performed. The embodiment adopts PLC control to realize automatic operation. Such as: the proximity switch sends out a signal whether the work piece 10 is arranged on the work station, and the PLC system controls the rotary workbench 1 to rotate and the splitting operation of the split work piece 10 is completed. The operation is stable and reliable, and the safety is good.
