DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 2 and Figure 3 As shown, the present invention provides a molding device for producing a ball cage retainer, including a pipe 5, a clamp is provided at the bottom end of the pipe 5 to clamp the ball cage retainer and drive it to deflect, the clamp includes a base 1 as a support, the base 1 is fixedly connected to the bottom end of the pipe 5, a plurality of clamping cylinders 2 are fixedly connected to the base 1 at equal intervals, a motor 3 is fixedly connected to the output end of the clamping cylinder 2, and a friction wheel 4 is fixedly connected to the output end of the motor 3.

[0017] When grinding the window of the ball cage holder, the ball cage holder is put on the pipe 5 and moved downward until the bottom of the ball cage holder is located between the friction wheels 4. At this time, the clamping cylinder 2 drives the friction wheel 4 to clamp and fix the ball cage holder, and after the motor 3 is started, it will drive the friction wheel 4 to rotate to drive the ball cage holder to rotate.

[0018] like Figure 4-Figure 8 The pipe 5 is provided with a guide groove 6 in the radial direction, two sliders 7 penetrate the guide groove 6 and slide with the guide groove 6, an electric cylinder 23 is provided between the two sliders 7 to adjust the spacing between the two sliders 7, two mounting plates 8 arranged opposite to each other are sleeved on the outside of the pipe 5, the sliders 7 are fixedly connected to the mounting plates 8, supports 9 are fixedly connected at equal intervals on the opposite sides of the two mounting plates 8, the supports 9 on the two mounting plates 8 are arranged in a staggered manner, a first internal spline tube 15 is rotatably installed on the support 9, and the first internal spline tube 15 is internally splined. A first spline shaft 17 is slidably matched, and a magnetic sleeve 20 made of magnetic material is slidably matched outside the first spline shaft 17. An internal hollow cylindrical grinding wheel 22 is fixedly connected to the end face of the magnetic sleeve 20. An electromagnet 19 is fixedly connected to the outer facade of the support 9. A compression spring 21 is fixedly connected to the outer wall of the first spline shaft 17 between the electromagnet 19 and the magnetic sleeve 20. The compression spring 21 applies elastic force to the magnetic sleeve 20. A rotating structure is provided on the end face of the mounting plate 8 to drive the first inner spline tube 15 to rotate.

[0019] The rotating structure is used to drive the first inner spline tube 15 to rotate. The rotation of the first inner spline tube 15 will drive the first spline shaft 17 to rotate. The rotation of the first spline shaft 17 will drive the magnetic sleeve 20 to rotate. The magnetic sleeve 20 is fixedly connected to the cylindrical grinding wheel 22. The rotation of the magnetic sleeve 20 will drive the cylindrical grinding wheel 22 to rotate synchronously. The diameter of the cylindrical grinding wheel 22 is smaller than the width of the ball cage holder window, so that the cylindrical grinding wheel 22 can be inserted into the window. When the electric cylinder 23 is working, the cylindrical grinding wheel 22 can move up and down, and the cylindrical grinding wheel 22 is pressed against the inner wall of the ball cage holder window through the electric cylinder 23. When the cylindrical grinding wheel 22 rotates, the inner wall of the window can be grinded and formed.

[0020] like Figure 7-Figure 11 As shown, the rotating structure includes an end face gear 10, which is rotatably mounted on the end face of the mounting plate 8. A transmission gear 12 is rotatably mounted on the inner wall of the support 9. The transmission gear 12 cooperates with the end face gear 10. A driven gear 16 is fixedly connected to the outer wall of the first inner spline tube 15, and the driven gear 16 matches the transmission gear 12.

[0021] When the end gear 10 is working, it will drive the transmission gear 12 to rotate. The transmission gear 12 is meshed with the driven gear 16. During the rotation of the transmission gear 12, the driven gear 16 will be driven to rotate. The driven gear 16 is fixedly connected to the first internal spline tube 15. When the driven gear 16 rotates, it will drive the first internal spline tube 15 to rotate.

[0022] like Figure 9-11 As shown, a stroke structure is provided on the end face of the transmission gear 12 to drive the first spline shaft 17 to perform linear reciprocating motion along the axial direction. The stroke structure includes a connecting block 14. The end of the first spline shaft 17 is rotatably mounted on the connecting block 14. A nut seat 13 is fixedly connected to the outside of the connecting block 14. A reciprocating screw 11 is coaxially fixedly connected to the end face of the transmission gear 12. The reciprocating screw 11 is threadedly matched with the nut seat 13.

[0023] Since the reciprocating screw 11 is fixedly connected to the transmission gear 12, the reciprocating screw 11 will be driven to rotate synchronously during the rotation of the transmission gear 12. Since the nut seat 13 and the reciprocating screw 11 are threadedly matched and the nut seat 13 cannot rotate, the nut seat 13 will be driven to perform linear reciprocating motion during the rotation of the reciprocating screw 11. During the movement of the nut seat 13, the first spline shaft 17 will be driven to move synchronously through the connecting block 14, so that the first spline shaft 17 drives the compression spring 21 to move. During the movement of the compression spring 21, the magnetic sleeve 20 is driven to move through the elastic force, and the magnetic sleeve 20 drives the cylindrical grinding wheel 22 to perform linear reciprocating motion along the axial direction.

[0024] When the cylindrical grinding wheel 22 is grinding the window, its linear reciprocating motion will constantly change the contact position of the inner wall of the window with the cylindrical grinding wheel 22 to prevent the cylindrical grinding wheel 22 from being continuously worn locally.

[0025] like Figure 9-11 As shown, a driving structure is provided in the pipe fitting 5 for driving the end face gear 10 to rotate, and the driving structure includes a second spline shaft 30 as a main shaft, and the bottom end of the second spline shaft 30 is rotatably mounted on the bottom of the pipe fitting 5, and two sliders 7 are slidably matched with the second spline shaft 30, and are slidably matched with the second inner spline tube 29 on the second spline shaft 30, and one end of the second inner spline tube 29 is rotatably connected to the L-shaped connecting piece 26, and a driving bevel gear 28 is fixedly connected to the outer wall of the other end of the second inner spline tube 29, and a bearing seat 23 is fixedly connected to the end surface of the mounting plate 8, and a transmission shaft 24 is rotatably mounted in the bearing seat 23, one end of the transmission shaft 24 passes through the connecting piece 26 and is fixedly connected to a driven bevel gear 27, and the driven bevel gear 27 matches the driving bevel gear 28, and the other end of the transmission shaft 24 passes through the notch 18 on the pipe fitting 5 and is fixedly connected to a driving gear 25, and the driving gear 25 matches the end face gear 10.

[0026] When the second spline shaft 30 serving as the main shaft is working, it will drive the second internal spline tube 29 to rotate. The second internal spline tube 29 is fixedly connected to the driving bevel gear 28. During the rotation of the second internal spline tube 29, the driving bevel gear 28 will be driven to rotate synchronously. The driving bevel gear 28 and the driven bevel gear 27 are meshed with each other. The rotation of the driving bevel gear 28 will drive the driven bevel gear 27 to rotate. The rotation of the driven bevel gear 27 drives the transmission shaft 24 to rotate. The rotation of the transmission shaft 24 drives the driving gear 25 to rotate. Since the driving gear 25 is meshed with the end gear 10, the driving gear 25 will drive the end gear 10 to rotate when it is running, thereby providing power for the entire device.

[0027] The working principle and use process of the present invention: Step 1: After the electromagnet 19 is energized, it generates an attractive magnetic force on the magnetic sleeve 20. Under the action of the magnetic force, the magnetic sleeve 20 compresses the compression spring 21 and drives the cylindrical grinding wheel 22 to slide on the first spline shaft 17 to reduce the radius of the circle where the multiple cylindrical grinding wheels 22 are located, making it easier for the cylindrical grinding wheels 22 to enter the ball cage holder.

[0028] Step 2: If Figure 1 As shown, the ball cage holder is sleeved on the pipe 5 and moves from top to bottom until all the cylindrical grinding wheels 22 enter the inside of the ball cage holder and align with the window. At this time, the clamping cylinder 2 is started, and the clamping cylinder 2 drives the friction wheel 4 to clamp the bottom of the ball cage holder; After the ball cage holder is clamped and fixed by the friction wheel 4, the electromagnet 19 stops working. At this time, under the elastic force of the compression spring 21, the cylindrical grinding wheel 22 stretches outward and passes through the window of the ball cage holder.

[0029] Step 3: If Fig.11 and Fig.12 As shown, the starting electric cylinder 23 adjusts the distance between the two sliders 7. Since a group of cylindrical grinding wheels 22 are set on each slider 7, after the distance between the two sliders 7 is adjusted, one group of cylindrical grinding wheels 22 abuts against the upper wall inside the window, and the other group of cylindrical grinding wheels 22 abuts against the lower wall inside the window.

[0030] Step 4: The second spline shaft 30 as the main shaft drives the second internal spline tube 29 to rotate. The second internal spline tube 29 is fixedly connected to the driving bevel gear 28. The second internal spline tube 29 rotates, which drives the driving bevel gear 28 to rotate synchronously. The driving bevel gear 28 and the driven bevel gear 27 are meshed with each other. The rotation of the driving bevel gear 28 drives the driven bevel gear 27 to rotate. The rotation of the driven bevel gear 27 drives the transmission shaft 24 to rotate. The rotation of the transmission shaft 24 drives the driving gear 25 to rotate. Since the driving gear 25 and the end gear 10 are meshed, the driving gear 25 drives the end gear 10 to rotate when it is running; When the end gear 10 is working, it will drive the transmission gear 12 to rotate. The transmission gear 12 is meshed with the driven gear 16. During the rotation of the transmission gear 12, the driven gear 16 will be driven to rotate. The driven gear 16 is fixedly connected to the first internal spline tube 15. When the driven gear 16 rotates, it will drive the first internal spline tube 15 to rotate. The rotation of the first inner spline tube 15 will drive the rotation of the first spline shaft 17, and the rotation of the first spline shaft 17 will drive the magnetic sleeve 20 to rotate. The magnetic sleeve 20 is fixedly connected to the cylindrical grinding wheel 22. The rotation of the magnetic sleeve 20 will drive the cylindrical grinding wheel 22 to rotate synchronously. The diameter of the cylindrical grinding wheel 22 is smaller than the width of the ball cage holder window, so that the cylindrical grinding wheel 22 can be inserted into the window. When the electric cylinder 23 is working, the cylindrical grinding wheel 22 can be moved up and down, and the cylindrical grinding wheel 22 is pressed against the inner wall of the ball cage holder window through the electric cylinder 23. When the cylindrical grinding wheel 22 rotates, the inner wall of the window can be grinded and formed; During the grinding and forming process, since one group of cylindrical grinding wheels 22 applies an upward force to the ball cage retainer, and the other group of cylindrical grinding wheels 22 applies a downward force to the ball cage retainer, and the forces applied by the two groups of cylindrical grinding wheels 22 are the same, the axial force on the ball cage retainer is always in a balanced state during the grinding process, so as to prevent the ball cage retainer from axially moving due to the pressure of the grinding wheel when the inner wall of the window is being ground.

[0031] Furthermore, during the grinding process, since the reciprocating screw 11 is fixedly connected to the transmission gear 12, the reciprocating screw 11 will be driven to rotate synchronously during the rotation of the transmission gear 12. Since the nut seat 13 and the reciprocating screw 11 are threadedly matched and the nut seat 13 cannot rotate, the nut seat 13 will be driven to perform linear reciprocating motion during the rotation of the reciprocating screw 11. During the movement of the nut seat 13, the first spline shaft 17 will be driven to move synchronously through the connecting block 14, so that the first spline shaft 17 drives the compression spring 21 to move. During the movement of the compression spring 21, the elastic force drives the magnetic sleeve 20 to move. The magnetic sleeve 20 drives the cylindrical grinding wheel 22 to perform linear reciprocating motion along the axial direction. The linear reciprocating motion will constantly change the contact position of the inner wall of the window on the cylindrical grinding wheel 22 to prevent local and continuous wear of the cylindrical grinding wheel 22.

[0032] Step 5: Start the motor 3, which drives the friction wheel 4 to deflect back and forth within a certain angle, so that the cylindrical grinding wheel 22 can scan the entire inner wall of the window.

[0033] Step 6: The above two groups of cylindrical grinding wheels 22 only grind one of the upper and lower sides of the window. When grinding the other side of the window where each group of grinding wheels is located, it is necessary to start the electric cylinder 23 again to change the height of the two groups of cylindrical grinding wheels 22, so that the two groups of cylindrical grinding wheels 22 are respectively in contact with the ungrinded side of the window to ensure all-round window grinding.

[0034] Compared with the prior art, the ball cage retainer production molding equipment provided by the present invention can independently polish all the windows at the same time when polishing multiple windows of the ball cage retainer, saving the time required for replacing the polished windows during the polishing process to improve production efficiency; in addition, during the polishing process, the two groups of cylindrical grinding wheels 22 apply forces on the inner wall of the window with the same magnitude and opposite directions. Therefore, the axial force on the ball cage retainer is always in a balanced state during the polishing process, so as to prevent the ball cage retainer from axially offset due to the pressure of the grinding wheel when the inner wall of the window is polished, thereby improving the polishing quality.
