[0004] The production and processing of some bearings have certain defects. For example, there are differences in bearing wall thickness and the bearing cannot be placed centrally in the induction equipment.

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] See also Figure 1-Figure 6 As shown, a bearing processing heat treatment equipment with uniform heating includes a heat treatment workbench 11 and a heating controller 12 installed on the heat treatment workbench 11, and the bearing processing heat treatment equipment also includes an induction line 13 connected to the heating controller 12, an induction coil 14 connected to the induction line 13, two groups of support seats 2 symmetrically fixedly installed on the heat treatment workbench 11 about the induction coil 14, an active rotating rod 21 rotatably installed on the support seat 2, and a driven rotating rod 22 movably installed on the support seat 2; a moving component 23 for adjusting the distance between the driven rotating rod 22 and the active rotating rod 21 is provided on the support seat 2; a rotating seat 24 is fixedly connected to the driven rotating rod 22, and a clamping component 25 for clamping and limiting the bearing workpiece is provided on the rotating seat 24; the clamping components 25 are symmetrically distributed on both sides of the induction coil 14, and alternately clamp the bearing and move it into the induction coil 14.

[0036] The bearing sleeve is arranged on the outside of the clamping component 25, and the heat treatment processing position of the bearing is quickly clamped by the clamping component 25. The rotating seat 24 and the clamping component 25 are pushed to move towards the induction coil 14 by the moving component 23, so that the clamped bearing is pushed into the center of the induction coil 14, and the induction coil 14 is quickly heated by the heating controller 12 and the induction line 13. The induction coil 14 performs heat treatment on the clamped bearing on the inside. While the heat treatment is being processed, the active rotating rod 21 is controlled to rotate. The active rotating rod 21 drives the driven rotating rod 22 to rotate synchronously through the guide prism 231. The driven rotating rod 22 drives the rotating seat 24 and the clamping component 25 to rotate synchronously. The clamping component 25 drives the clamped bearing to rotate in the induction coil 14, so that the heat is evenly transmitted and distributed on the bearing, avoiding local overheating of the bearing, thereby reducing the probability of deformation and damage of the bearing due to heating.

[0037] See also Figure 4-Figure 9 As shown, the clamping assembly 25 includes a sliding hole 251 opened at an equal angle on the rotating seat 24, and a clamping claw 252 is slidably connected to the sliding hole 251.

[0038] The bearing sleeve is arranged on the outside of the clamping claws 252, and the multiple clamping claws 252 are controlled to move toward the outside of the rotating seat 24 along the direction of the sliding hole 251. The multiple clamping claws 252 move synchronously and clamp on the inner side of the bearing, so as to quickly limit the heat treatment processing position of the bearing. In addition, the clamping of the multiple clamping claws 252 can keep the bearing centered in the induction ring 14, so that the circumferential surface of the bearing can be heated more evenly.

[0039] See also Figure 4-Figure 9As shown, a clamping cylinder 253 is embedded in the driven rotating rod 22, and a positioning plate 254 is connected to the telescopic end of the clamping cylinder 253. The positioning plate 254 is coaxially movably arranged in the rotating seat 24, and a push rod 255 is rotatably connected to the positioning plate 254. The push rod 255 is rotatably assembled with the clamping claw 252.

[0040] The operating clamping cylinder 253 pushes the positioning plate 254 to move horizontally in the rotating seat 24, and the two ends of the push rod 255 connected between the positioning plate 254 and the clamping claw 252 rotate accordingly. The rotating push rod 255 pushes the clamping claw 252 to slide along the sliding hole 251, thereby realizing the function of synchronously driving multiple clamping claws 252.

[0041] See also Figure 7-Figure 9 As shown, a temperature sensing probe 3 for detecting the temperature of the inner ring of the bearing is embedded and installed on the end surface of the clamping claw 252.

[0042] After the clamping claw 252 is clamped and confined to the inner ring of the bearing, during the heat treatment of the bearing, the temperature sensing probe 3 on the clamping claw 252 can sense the heating temperature of the bearing in real time, and the heat treatment processing temperature can be controlled in time according to the sensed temperature to avoid damage to the workpiece due to excessive heating temperature. In addition, the clamping claw 252 can measure the temperature of the inner wall of the bearing to improve its protectiveness and avoid damage to the outer wall of the bearing when the clamping claw 252 is set under high temperature conditions.

[0043] See also Figure 4-Figure 6 As shown, the moving assembly 23 includes a guide prism 231 fixedly connected to the active rotating rod 21, the guide prism 231 penetrates and is slidably connected to the driven rotating rod 22, a shift cylinder 232 is fixedly installed on the support seat 2, a shift seat 233 is fixedly installed at the telescopic end of the shift cylinder 232, and the shift seat 233 is rotatably assembled with the driven rotating rod 22; a groove structure matching the guide prism 231 is opened in the driven rotating rod 22, and the guide prism 231 is slidably installed in the groove structure opened inside the driven rotating rod 22.

[0044] After the bearing is confined on the clamping assembly 25, the shift cylinder 232 is operated to push the shift seat 233 to move horizontally, and the shift seat 233 drives the driven rotating rod 22 to slide on the guide prism 231, and the driven rotating rod 22 pushes the rotating seat 24 and the clamping assembly 25 to move toward the direction of the induction coil 14. When the clamping assembly 25 on one side of the induction coil 14 clamps the bearing for heat treatment, the clamping assembly 25 on the other side of the induction coil 14 clamps and assembles a new bearing and waits for heating. When the bearing in the induction coil 14 completes the heat treatment, the shift cylinder 232 is operated to control the clamping assembly 25 and the bearing to move away from the induction coil 14, and the shift cylinder 232 on the other side of the induction coil 14 pushes the clamping assembly 25 and the bearing to enter the induction coil 14 for induction processing. The clamping assemblies 25 on both sides of the induction coil 14 alternately control the clamped bearings for heat treatment processing to improve processing efficiency.

[0045] See also Figure 5-Figure 7 As shown, the driven rotating rod 22 is provided with a discharging assembly 4 for independently discharging materials after hot processing of the auxiliary bearing.

[0046] When the shift cylinder 232 drives the driven rotating rod 22 and the clamping assembly 25 to move away from the induction coil 14, the loosened bearing on the clamping assembly 25 can unload the material autonomously with the help of the discharging assembly 4.

[0047] See also Figure 5-Figure 7 As shown, the discharge assembly 4 includes a cross bar 41 fixed on the support seat 2, a discharge push pin 42 is fixedly mounted on the cross bar 41, and a discharge port 43 for bearing drop is provided on the heat treatment workbench 11.

[0048] When the shift cylinder 232 is operated to drive the driven rotating rod 22, the rotating seat 24, and the clamping assembly 25 to move away from the induction coil 14, the bearing on the clamping assembly 25 is loosened first, and the bearing contacts the discharge push pin 42 and separates from the clamping claw 252. The separated bearing is discharged autonomously through the discharge port 43.

[0049] See also Figure 1-Figure 4 , Figure 10-12 As shown, a speed change assembly 5 is provided on the support seat 2 for controlling the rotation speed of the active rotating rod 21 according to the bearing diameter and thickness factors.

[0050] According to the wall thickness and diameter of the processed bearing, the processing speed of the driving active rotating rod 21 is adjusted to ensure that the bearing can be evenly subjected to the heat treatment process.

[0051] See also Figure 1-Figure 4 , Figure 10-12 As shown, the speed change assembly 5 includes a fixed ring 51 fixedly mounted on the support seat 2, an inner gear ring 52 is fixedly mounted on the fixed ring 51, a planet carrier 53 is coaxially connected to the active rotating rod 21, a tooth column 54 is coaxially fixedly connected to the planet carrier 53, and a plurality of planetary gears 55 are equiangularly mounted on the planet carrier 53, the outer sides of the plurality of planetary gears 55 distributed circumferentially are meshed and assembled with the inner gear ring 52, and the inner sides of the plurality of planetary gears 55 distributed circumferentially are meshed and assembled with a sun gear 56; a tooth groove 57 is opened on the sun gear 56 along the axial direction, and the sun gear 56 moves laterally and is engaged with the tooth column 54 through the tooth groove 57.

[0052] When the sun gear 56 moves laterally through the tooth groove 57 and engages with the outside of the gear column 54, the sun gear 56 is engaged with the planet carrier 53. When the sun gear 56 rotates, the planet carrier 53 and the active rotating rod 21 are driven to rotate synchronously through the engaging structure. The active rotating rod 21 controls the clamping assembly 25 and the clamped bearing to rotate, and controls the sun gear 56 to move laterally so that it is meshed and assembled with the planetary gear 55. At this time, the sun gear 56 and the gear column 54 are separated from each other. When the sun gear 56 rotates, the sun gear 56, the planetary gear 55 and the inner gear ring 52 are meshed and assembled, and the planetary gear 55 is driven to rotate in a circle under the action of meshing transmission. The diameter of the sun gear 56 is larger than the diameter of the planetary gear 55, and the gear transmission ratio increases. The planetary gear 55 drives the planet carrier 53 to rotate faster, thereby driving the active rotating rod 21 to rotate faster. The sun gear 56 moves to different positions, and the processing speed of the bearing clamped in the induction ring 14 can be adjusted.

[0053] See also Figure 10-12 As shown, a speed regulating cylinder 561 is fixedly mounted on the support seat 2 , a mounting frame 562 is fixedly mounted on the telescopic end of the speed regulating cylinder 561 , a motor 563 is fixedly mounted on the mounting frame 562 , and an output end of the motor 563 is fixedly connected to the sun gear 56 .

[0054] The running motor 563 controls the rotation of the sun gear 56. According to the bearing wall thickness and diameter, the corresponding position of the sun gear 56 is adjusted to adjust the speed of the bearing clamping processing. The running speed regulating cylinder 561 pushes the mounting frame 562 to move horizontally. The mounting frame 562 drives the motor 563 and the sun gear 56 to move synchronously, and adjusts the corresponding position between the sun gear 56 and the gear column 54 and the planetary gear 55.

[0055] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
