Description

Technical Field

[0001] This utility model relates to the technical field of bearing heat fitting, and in particular to a temperature-controllable heating device for heat fitting of bearing inner ring. Background Technology

[0002] In the field of mechanical manufacturing, the interference fit between the inner ring of a bearing and the shaft is often achieved using a heat fitting process, which involves heating the inner ring to expand it and then quickly assembling it. Currently, heating plate technology has matured, and heating plates on the market generally have precise temperature regulation functions, which can stably control the heating temperature according to a preset program to meet the requirements of conventional heat fitting processes.

[0003] Based on the technical effects of existing technologies and solutions, there are still areas that need optimization: most devices can only heat a single bearing inner ring at a time. When multiple bearings of the same specification need to be assembled, the clamping and heating process must be repeated, resulting in reduced production efficiency. Although some multi-station heating equipment can process multiple bearings at the same time, each station is independent and dispersed, making it impossible to achieve synchronous rotation and centralized sealing, resulting in serious heat loss. Furthermore, due to inconsistent heating environments, it is difficult to ensure the uniformity of heating effect for multiple bearing inner rings.

[0004] In addition, traditional clamping structures have poor versatility and are difficult to adapt to bearing inner rings of different sizes. When switching product specifications, it is necessary to frequently change the clamps manually, which is cumbersome and reduces work efficiency. Utility Model Content

[0030] Example 1

[0031] Reference Figures 1-4 6, being the first embodiment of this utility model, provides a support mechanism 100 that enables the device to provide overall stable support, drive the inner ring of the bearing 201c to rotate, and seal the heating area.

[0032] The support mechanism 100 includes a support plate 101, a support leg 102 is provided at the bottom of the support plate 101, and a rotating assembly 103 and a sealing component 104 are respectively provided at the top of the support plate 101.

[0033] The rotating assembly 103 includes a fixing groove 103a opened at the bottom of the support plate 101, a motor 103b is provided inside the fixing groove 103a, and the output end of the motor 103b is connected to a rotating disk 103c, which is located at the top of the support plate 101.

[0034] The sealing component 104 includes movable grooves 104a formed at both ends of the top of the support plate 101. A first electric push rod 104b is provided on the surface of the movable groove 104a. A movable block 104c is connected to the output end of the first electric push rod 104b. A sealing ring 104d is fixedly connected to the top of the movable block 104c.

[0035] Specifically, the rotating component 103 can precisely drive the inner ring of the bearing 201c to perform stable circumferential motion. When the motor 103b starts, its output end transmits power to the rotating disk 103c, causing the clamping component 201 and the inner ring of the bearing 201c to rotate synchronously. This ensures that all parts of the inner ring are heated evenly during the heating process, effectively avoiding problems such as deformation of the inner ring or insufficient heating caused by uneven local heating. The sealing component 104 can quickly form a closed heating space. After the first electric push rod 104b is started, it pushes the moving block 104c to slide in the moving groove 104a, causing the sealing ring 104d to move inward and precisely engage. The high-temperature resistant sealing strip at the engagement point of the sealing ring 104d fits tightly, ensuring the sealing of the heating area and effectively reducing heat loss.

[0036] Furthermore, the heating plate 202b is embedded in the placement groove 202a, the power is turned on to start heating, and the rotating disk 103c drives the inner ring to rotate so that the heating is uniform; then the motor 103b in the bottom fixing groove 103a of the support plate 101 is started, and the output end of the motor 103b drives the rotating disk 103c to rotate via the coupling. The rotating disk 103c drives the clamping assembly 201 and the inner ring to rotate synchronously through the sliding block 201b. At the same time, the first electric push rod 104b is started, which pushes the moving block 104c to slide in the moving groove 104a, driving the sealing ring 104d to move inward and dock. The high temperature resistant sealing strip at the docking point of the sealing ring 104d ensures the formation of a closed heating space and reduces heat loss.

[0037] Example 2

[0038] Reference Figure 2 , 4 ~6, the second embodiment of this utility model, provides a heating mechanism 200 to achieve stable clamping and heating of the inner ring of bearings 201c of different sizes.

[0039] The heating mechanism 200 includes a clamping assembly 201 disposed on the top of the rotating assembly 103, and a heating element 202 is disposed on the inner wall of the clamping assembly 201.

[0040] The clamping assembly 201 includes a clamping ring 201a disposed on the top of the rotating disk 103c. Several clamping rings 201a are provided and are distributed circumferentially. A sliding block 201b is fixedly connected to the bottom of the clamping ring 201a, and a bearing 201c is provided on the outside of the clamping ring 201a.

[0041] The heating component 202 includes a placement groove 202a opened on the top of the clamping ring 201a, a heating plate 202b is provided on the surface of the placement groove 202a, and a lifting handle 202c is provided on the top of the heating plate 202b.

[0042] The inner side of the clamping ring 201a is provided with a pressing block 203, the bottom of the pressing block 203 is provided with a pressing ring 204, the bottom of the pressing ring 204 is provided with a second electric push rod 205 for transmission, and the bottom of the second electric push rod 205 is fixedly connected to the top of the rotating disk 103c.

[0043] The bottom of the extrusion block 203 is provided with a trapezoidal groove 206, and the outer side of the extrusion ring 204 is in contact with the inner side of the trapezoidal groove 206.

[0044] The top of the rotating disk 103c has four stroke grooves 207 at each of its four ends. Each stroke groove 207 has a limiting rod 208 on its surface. A spring 209 is fitted on the surface of the limiting rod 208. The left and right sides of the spring 209 are fixedly connected to the inner side of the stroke groove 207 and the outer side of the sliding block 201b, respectively.

[0045] Specifically, by setting up the clamping assembly 201 and the heating component 202, bearings 201c of different diameters can be clamped and their inner rings can be heated.

[0046] Furthermore, the bearing 201c to be heated is sleeved on the outside of the clamping ring 201a, and then the second electric push rod 205 is activated, which pushes the extrusion ring 204 to rise. The extrusion ring 204 moves along the trapezoidal groove 206 at the bottom of the extrusion block 203, causing the extrusion block 203 to move inward. Multiple extrusion blocks 203 work together to clamp the inner ring, ensuring the stability of the inner ring during rotational heating. When the clamping ring 201a moves, it will simultaneously drive the sliding block 201b to move, and the movement of the sliding block 201b can compress the spring 209, increasing the stability of the rotating disk 103c during rotation.

[0047] Example 3

[0048] Reference Figures 1-6 This is the third embodiment of the present invention. The difference between this embodiment and the third embodiment is that this embodiment provides a temperature-controllable heating device for heat fitting of the inner ring of bearing 201c.

[0049] When using this heating device;

[0050] First, the bearing 201c to be heated is placed on the outside of the clamping ring 201a. Then, the second electric push rod 205 is activated, which pushes the extrusion ring 204 to rise. The extrusion ring 204 moves along the trapezoidal groove 206 at the bottom of the extrusion block 203, causing the extrusion block 203 to move inward. Multiple extrusion blocks 203 work together to clamp the inner ring, ensuring that the inner ring is stable during rotational heating.

[0051] Next, the heating plate 202b is embedded into the placement groove 202a, the power is turned on to start heating, and the rotating disk 103c drives the inner ring to rotate so that the heating is uniform; then the motor 103b in the bottom fixing groove 103a of the support plate 101 is started. The output end of the motor 103b drives the rotating disk 103c to rotate through the coupling. The rotating disk 103c drives the clamping assembly 201 and the inner ring to rotate synchronously through the sliding block 201b. At the same time, the first electric push rod 104b is started, which pushes the moving block 104c to slide in the moving groove 104a, driving the sealing ring 104d to move inward and dock. The high temperature resistant sealing strip at the docking point of the sealing ring 104d ensures the formation of a closed heating space and reduces heat loss.

[0052] Finally, after heating is complete, the first electric push rod 104b is activated to separate the sealing ring 104d, and then the second electric push rod 205 is activated to lower the extrusion ring 204. The extrusion block 203 releases the inner ring under the action of the spring 209. Finally, the heated inner ring is manually removed to complete the heat installation.

[0053] In summary, the design of the support mechanism 100 and the heating mechanism 200 has enabled efficient and uniform heating of the bearing 201c inner ring during the heat fitting process, from stable support and clamping of bearings 201c of different sizes to sealing, thereby improving the efficiency of the heat fitting of the bearing 201c inner ring.
