Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for bearing inner and outer rings, and specifically to a device capable of heat treating the inner and outer rings of bearings. Background Technology

[0002] Heat treatment of the inner and outer rings of a bearing involves heating the bearing to a red-hot state to carbonize it. After heating to red-hot, it is necessary to cool it down. Rapid cooling can significantly improve the strength of the bearing. Traditional heat treatment involves placing the bearing workpiece on a fixed part, heating it to a fixed temperature, and then transporting it to a cooling mechanism. The intermediate operations often require manual intervention. After cooling, it is necessary to observe whether the process is successful and whether repeated heating is needed. The overall efficiency of heat treatment is low.

[0003] Existing heat treatment devices for bearing inner and outer rings have a single function and cannot be integrated with operations such as quenching or conveying to the next inspection production line, resulting in low production efficiency. For example, a bearing outer ring processing device disclosed in CN221777956U includes a mesh belt furnace and a chain mesh belt. The chain mesh belt is installed in the frame box of the mesh belt furnace, and a ring support mechanism is also included. The ring support mechanism includes a pressure plate, insert post, limit bar, cross connecting plate, outer limit bar, inner limit bar, support plate, support block, and fixed rod. The pressure plate is pressed onto the surface of the chain mesh belt. A ring-supporting mechanism is installed at the chain mesh belt of the mesh belt furnace. The ring-supporting mechanism presses against the surface of the chain mesh belt to form a structure that vertically supports the outer ring of the bearing. The pressure plate of the ring-supporting mechanism has multiple sets of strip-shaped frames that can cooperate with the outer and inner limit strips to vertically support the outer ring of the bearing. Then, as the pressure plate is carried into the mesh belt furnace for heat treatment, the outer ring of the bearing, which is vertically supported by the ring-supporting mechanism for heat treatment, has a larger exposed area compared to the heat treatment area where the entire surface of the outer ring of the bearing lies on the chain mesh belt. This ensures that the outer ring of the bearing can be better fed into the mesh belt furnace for heat treatment.

[0004] Therefore, it is necessary to invent a device that can perform heat treatment on the inner and outer rings of a bearing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for heat treatment of the inner and outer rings of a bearing, in order to solve the problems in the technology of heat treatment of bearing workpieces that cannot be combined with cooling and quenching operations, and that cannot be connected with the next production line, resulting in low production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for heat treating the inner and outer rings of a bearing includes a processing device body, a heating mechanism, and a positioning clamping part. A movable door is slidably connected to the processing device body. The processing device body is divided into upper and lower parts by an elastic sleeve. The upper part is filled with coolant, and the height of the coolant part is lower than that of the clamping mechanism. The lower part is a receiving cavity. The heating mechanism is installed on the top of the processing device body. The heating mechanism extends into the processing device body and is connected to an electromagnetic heating coil. The processing device body is also provided with a clamping mechanism, which is equipped with mechanical grippers.

[0008] The elastic sheath is provided with at least two positioning clamping parts, and the bottom of the positioning clamping parts is sealed to the elastic sheath by adhesive bonding.

[0009] The cavity is provided with a lifting part that can move along the bottom surface of the main body of the processing device. After the lifting part moves to the bottom of the corresponding positioning clamping part, it lifts the positioning clamping part until the bearing workpiece is completely exposed to the coolant, and the electromagnetic heating coil is located at the center of the bearing workpiece.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] 1. This utility model sets up two parts inside the main body of the processing device, and uses the coolant in the upper part to cool the bearing workpiece heated to the red-hot temperature. The combination of heating and quenching processes improves the strength of the bearing and extends its service life.

[0012] 2. This utility model can lift the positioning clamping part to a fixed height, heat it at the fixed height by the electromagnetic heating coil, and then lower it into the coolant. After repeating this process several times, the heating and quenching of the bearing workpiece is completed. Finally, it is transported to the next production line for inspection by the clamping mechanism. The clamping mechanism can be connected to the next production line, and the dual-station heating and cooling operation improves the production efficiency and the processing efficiency of the bearing workpiece.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model provides, for example Figures 1-5 The device shown is capable of heat treating the inner and outer rings of a bearing, including a processing device body 1, a heating mechanism 2 and a positioning clamping part 4, wherein a movable door 101 is slidably connected to the processing device body 1;

[0022] The main body 1 of the processing device is divided into upper and lower parts by an elastic sleeve 102. The upper part is filled with coolant and the height of the coolant part is lower than that of the clamping mechanism 3. The lower part is a receiving cavity.

[0023] A heating mechanism 2 is installed on the top of the main body 1 of the processing device. The heating mechanism 2 extends into the main body 1 of the processing device and is connected to an electromagnetic heating coil 201.

[0024] The main body 1 of the processing device is also provided with a clamping mechanism 3, and the clamping mechanism 3 is provided with a mechanical gripper 301;

[0025] The elastic leather sleeve 102 is provided with at least two positioning clamping parts 4, and the bottom of the positioning clamping part 4 is sealed to the elastic leather sleeve 102 by adhesive bonding.

[0026] A lifting section is provided within the receiving cavity, which can move along the bottom surface of the main body 1 of the processing device. After the lifting section moves to below the corresponding positioning clamping section 4, it lifts the positioning clamping section 4 until the bearing workpiece is completely exposed above the coolant, and the electromagnetic heating coil 201 is positioned at the center of the bearing workpiece. This invention enables the heating and cooling of multiple bearing workpieces by means of the reciprocating movement of the lifting section between the two positioning clamping sections 4.

[0027] This utility model utilizes the up-and-down movement of the positioning clamping part 4 to heat the bearing workpiece placed on it. When the positioning clamping part 4 is raised, the electromagnetic heating coil 201 is located at the center of the bearing workpiece to be processed, and the entire workpiece is heated and glows red through the electromagnetic heating coil 201.

[0028] The positioning and clamping part 4 is equipped with multiple clamping members 401 arranged in a ring array and capable of moving radially to clamp the bearing workpiece.

[0029] The positioning clamping part 4 is provided with water-permeable holes 402 evenly, and the positioning clamping part 4 is a trumpet shape that is wider at the top and narrower at the bottom.

[0030] Furthermore, in order to ensure the stability of the lifting and lowering movement of the positioning clamping part 4, a vertically arranged guide shaft (not shown in the figure) can be installed on the inner wall of the main body 1 of the processing device so that the positioning clamping part 4 can be penetrated by the guide shaft.

[0031] The lifting section includes a lifting plate 403 that can move laterally along the bottom surface of the main body 1 of the processing device and rise and fall vertically. The lifting plate 403 is located below the elastic sleeve 102 and is not connected to the elastic sleeve 102.

[0032] The bottom of the lifting plate 403 is connected to a scissor-type retraction frame 404, which controls the lifting and lowering of the lifting plate 403. A cylinder 405 is installed inside the scissor-type retraction frame 404, and a push rod 406 is connected to the cylinder 405. The push rod 406 is connected to the bottom surface of the lifting plate 403. The positioning clamping part 4 moves up and down controlled by the bottom cylinder 405 and the scissor-type retraction frame 404. When it moves down, the heated bearing workpiece is lowered into the coolant; when it is raised, the bearing workpiece is reheated. Heating and cooling can be performed according to the process settings.

[0033] The bottom of the scissor-type retractable frame 404 is equipped with a slide rail 407 that is distributed in the same direction as the two positioning clamping parts 4. The bottom of the scissor-type retractable frame 404 can move along the slide rail 407 by means of a motor-driven gear rack mechanism.

[0034] The clamping mechanism 3 is equipped with a motor 303, and a gear set 302 is connected to the shaft of the motor 303. The gear set 302 drives the mechanical gripper 301 to open and close.

[0035] The mechanical gripper 301 can be connected to an external connecting rod, and the mechanical gripper 301 can move outside the main body 1 of the processing device.

[0036] The maximum lifting height of the lifting plate 403 is such that it can abut against the bottom surface of the elastic sleeve 102 and make the elastic sleeve 102 bulge. The positioning clamping part 4 is lifted out of the surface of the coolant. A partition plate 103 is fixedly installed in the middle of the elastic sleeve 102 and sealed to the side wall of the main body 1 of the processing device on both sides. The elastic sleeve 102, the partition plate 103 and the inner side wall of the main body 1 of the processing device together form a tank structure for containing coolant. The height of the partition plate 103 is higher than the height of the coolant.

[0037] After the bearing workpiece has undergone multiple heating and cooling processes, it is finally clamped by the mechanical gripper 301 and transported to the next inspection production line.

[0038] Working principle of this utility model:

[0039] Refer to the instruction manual appendix Figures 1-3 First, the bearing to be processed is placed on the clamping mechanism 3, and the mechanical gripper 301 is used to transport it to the positioning clamping part 4, where it is clamped and fixed by multiple positioning clamping parts 4.

[0040] Refer to the instruction manual appendix Figures 3-5 The bearing workpiece on the positioning clamping part 4 is lifted by the cylinder 405 and the scissor-type retraction frame 404 to the position of the electromagnetic heating coil 201. The heating mechanism 2 starts to work, continuously heating the bearing workpiece to the temperature set by the process and then holding it at that temperature. Then it is lowered into the coolant for cooling. The coolant can be water or oil, thereby improving the strength of the bearing workpiece. After being quenched, it is lifted again and transported to the next inspection production line by the mechanical gripper 301.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
