Description

Technical Field

[0001] This utility model relates to quenching devices, and more particularly, to a ball cage ultra-precision induction quenching device. Background Technology

[0002] like Figure 1 As shown, a ball cage includes a ball cage body 90, and a gear tooth 91 is provided on the top of the ball cage body 90.

[0003] To ensure the wear resistance of the ball cage body and gear teeth, the ball cage needs to be quenched. However, the ball cage as a whole also needs high fatigue strength and impact resistance. It is difficult to meet the heat treatment requirements of the ball cage by using overall heat treatment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a ball cage ultra-precision induction hardening device, which has the function of local heat treatment.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a ball cage ultra-precision induction hardening device, including a mounting frame, on which a driving component, a clamping component, a high-frequency hardening component and a cooling component are provided. The driving component is used to drive the clamping component to fix the ball cage body and drive the ball cage body through the high-frequency hardening component and the cooling component. The high-frequency hardening component includes a high-frequency induction heating coil, which is arranged above the cooling component.

[0006] Preferably, the clamping assembly includes an upper clamping member and a lower clamping member, and the driving assembly includes a power source, a first guide rod, a second guide rod, and a lead screw. The upper clamping member and the lower clamping member are slidably disposed on the first guide rod and the second guide rod. The lower clamping member is threadedly engaged with the lead screw. The power source drives the lead screw to rotate and drives the lower clamping member to move up and down. After the upper clamping member and the lower clamping member are engaged and clamped, the upper clamping member moves up and down following the lower clamping member.

[0007] Preferably, the upper clamping member includes a base plate, an upper clamping block, and a clamping block mounting post. The clamping block mounting post is fixedly mounted on the base plate and used to fix the upper clamping block. A pair of linear bearings are also provided on the base plate, and the two linear bearings respectively cooperate with guide rod one and guide rod two. A handle is also provided on the clamping block mounting post.

[0008] Preferably, the lower clamping member includes a second base plate and a lower clamping block. The lower clamping block is fixedly mounted on the second base plate. A pair of linear bearings are provided on the second base plate. The two linear bearings respectively cooperate with guide rod one and guide rod two. A copper nut is also fixedly mounted on the second base plate. The copper nut is threadedly engaged with the lead screw.

[0009] Preferably, the lower clamping block includes a base, a positioning platform, and a positioning rod. The base is fixedly mounted on the second base plate, and the positioning rod is located at the center of the positioning platform and fixed to the base. The mounting frame is also provided with a limit rod. When the driving assembly drives the lower clamping member to move downward and touch the limit rod, the limit rod pushes the positioning platform out and retracts the positioning rod into the positioning platform.

[0010] Preferably, the positioning platform has a sleeve at its bottom, which extends into the base. The positioning rod is located in the center hole of the sleeve. The positioning rod has a first fixing hole in the horizontal direction. The sleeve has a second oblong hole in the horizontal direction. Pins are installed in the first fixing hole, the second fixing hole, and the second oblong hole. A spring is also installed between the sleeve and the positioning rod. A limit rod is also installed on the mounting bracket, and the limit rod is located at the bottom of the sleeve.

[0011] Preferably, the cooling assembly includes a cooling ring, the cooling ring having a cooling channel inside, and the inner sidewall of the inner hole of the cooling ring having a plurality of water outlet holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By placing a high-frequency induction heating coil around the outside of the ball cage body, the outer surface of the ball cage is heated. With the help of a cooling component, the heated area is quickly cooled, thus completing the local surface hardening of the ball cage. This ensures the surface hardness while giving it high fatigue strength and impact resistance. 2. By setting up a positioning platform, positioning rod and limiting rod, after the ball cage is quenched, the limiting rod abuts against the sleeve, causing the positioning rod to retract relatively, thereby preventing the ball cage from getting stuck on the positioning rod after heating and cooling and being unable to be removed. Mechanically pushing it out can reduce the jamming problem after quenching. 3. The installation method between the upper clamping block and the clamping block mounting column, pin and positioning rod makes it easy to replace the upper clamping block and positioning rod, making the equipment suitable for products of various models and sizes.

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0016] A ball cage ultra-precision induction hardening device includes a mounting frame 1. The mounting frame 1 is equipped with a drive assembly 2, a clamping assembly 3, a high-frequency hardening assembly 4, and a cooling assembly 5. The drive assembly 2 is used to drive the clamping assembly 3 to fix the ball cage body 90 and to drive the ball cage body 90 through the high-frequency hardening assembly 4 and the cooling assembly 5. The high-frequency hardening assembly 4 includes a high-frequency induction heating coil 6, which is arranged above the cooling assembly 5. A water tank 7 is also provided at the bottom of the mounting frame 1 to receive the cooling liquid flowing out of the cooling assembly 5. A cooler and a water pump can also be connected between the cooling assembly 5 and the water tank 7 through a pipeline to allow the cooling liquid to be circulated.

[0017] The clamping assembly 3 includes an upper clamping member 8 and a lower clamping member 9. The driving assembly 2 includes a power source 10, a first guide rod 11, a second guide rod 12, and a lead screw 13. The upper clamping member 8 and the lower clamping member 9 are slidably mounted on the first guide rod 11 and the second guide rod 12. The first guide rod 11 and the second guide rod 12 are the same and are both straight rods. The lower clamping member 9 is threadedly engaged with the lead screw 13. The power source 10 is a servo motor. One end of the lead screw 13 is fixed to the output end of the servo motor, thereby driving the lead screw 13 to rotate and causing the lower clamping member 9 to move up and down. After the upper clamping member 8 and the lower clamping member 9 are engaged and clamped, the upper clamping member 8 can follow the lower clamping member 9 to move up and down.

[0018] The upper clamping member 8 includes a base plate 14, an upper clamping block 15, and a clamping block mounting post 16. The clamping block mounting post 16 is fixedly mounted on the base plate 14 and the upper clamping block 15 is fixed by screws. A pair of linear bearings 17 are also provided on the base plate 14. The two linear bearings 17 cooperate with the guide rod 11 and the guide rod 2 12 respectively. A handle 18 is also provided on the clamping block mounting post 16. When loading or unloading is required, the upper clamping member 8 can be slid upward as a whole through the handle 18.

[0019] The lower clamping member 9 includes a second base plate 19 and a lower clamping block 20. The lower clamping block 20 is fixedly mounted on the second base plate 19. A pair of linear bearings 17 are also provided on the second base plate 19. The two linear bearings 17 are respectively engaged with the first guide rod 11 and the second guide rod 12. A copper nut 21 is also fixedly mounted on the second base plate 19. The copper nut 21 is threadedly engaged with the lead screw 13.

[0020] The lower clamping block 20 includes a base 22, a positioning platform 23, and a positioning rod 24. The positioning rod 24 and the upper clamping block 15 can position the ball cage to ensure uniform heating. The base 22 is fixedly mounted on the second base plate 19. The positioning rod 24 is located at the center of the positioning platform 23 and fixed to the base 22. The mounting frame 1 is also provided with a limit rod 25.

[0021] A sleeve 26 is fixedly installed at the bottom of the positioning platform 23. The sleeve 26 extends into the base 22. The positioning rod 24 is installed in the center hole of the sleeve 26. The positioning rod 24 has a first fixing hole 27 opened laterally. The sleeve 26 has a long waist hole 28 opened laterally. The base 22 has a second fixing hole 29 opened laterally. A pin 30 is installed in the first fixing hole 27, the second fixing hole 29 and the long waist hole 28. A spring 31 is also installed between the sleeve 26 and the positioning rod 24. A limiting rod 25 is installed at the bottom of the sleeve 26. When the driving assembly 2 drives the lower clamping member 9 to move downward and touch the limiting rod 25, the limiting rod 25 abuts against the sleeve 26 and pushes out the positioning platform 23. At this time, the long waist hole 28 and the pin 30 are in a sliding state. The positioning rod 24 retracts into the positioning platform 23, thereby preventing the ball cage from getting stuck on the positioning rod 24 after heating and cooling and being unable to be removed. Pushing it out mechanically can reduce the jamming problem that occurs after quenching. When the positioning platform 23 moves upward again, the spring 31, which is in a compressed state, releases its elastic potential energy, pushes the sleeve 26 downward, and causes the positioning rod 24 to extend again.

[0022] The cooling component 5 includes a cooling ring 32, with a cooling channel 33 inside the cooling ring 32. Several water outlet holes 34 are provided on the inner side wall of the inner hole of the cooling ring 32. The water outlet holes 34 are arranged in a ring array to ensure uniform cooling.

[0023] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
