Description

Technical Field

[0001] This utility model relates to the field of oil bath heater technology, specifically an oil bath type mechanical component heater. Background Technology

[0002] In the process of mechanical manufacturing and maintenance, some mechanical components (such as bearings, gears, bushings, etc.) need to be uniformly heated due to assembly requirements or performance optimization. For example, heating can expand the inner ring of a bearing to facilitate interference fit assembly with shaft parts. Oil bath heating has become one of the commonly used methods for heating mechanical components because of its stable heating temperature and uniform temperature distribution.

[0003] The prior art CN222724359U discloses a novel pull-up oil bath, including a device body. Two fixed equipment plates are fixedly installed on the top of the device body, and drive motors are fixedly installed on the sides of the two fixed equipment plates. A stainless steel mesh basket is set inside the device body. By placing an object in the stainless steel mesh basket and then putting it into the device body for oil bath heating, the drive motor drives the auxiliary hook to lift the stainless steel mesh basket, making it convenient to observe the liquid state inside the test tube.

[0004] However, the following shortcomings still exist in actual use: When the object is heated, the stainless steel wire basket is fixed and the heat transfer oil in the oil bath cavity only achieves temperature transfer through natural convection, which easily leads to differences in the flow speed of heat transfer oil in different areas of the wire basket, resulting in uneven heating of mechanical components in different positions in the wire basket.

[0005] Based on this, an oil bath type mechanical component heater is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-4As shown, an oil bath type mechanical component heater includes a housing 100, a controller 101 at the upper end of the housing 100, a heating groove 102 on the housing 100, a heating component in the heating groove 102, and a transmission groove 103 at the lower end of the housing 100 near the heating groove 102. A reciprocating swaying mechanism is provided in the transmission groove 103, and the reciprocating swaying mechanism is connected to a connecting plate 104. Both ends of the connecting plate 104 extend out of the transmission groove 103 and are connected to a lifting component. The lifting component is connected to a heating basket 105. The heating component heats the heating oil. The part to be heated is placed in the heating basket 105. The lifting component moves the heating basket 105 down into the heating groove 102, where it is submerged in the heating oil. The reciprocating swaying mechanism causes the heating basket 105 to sway back and forth, breaking the limitation of natural convection of the heat transfer oil and forming forced convection circulation, ensuring that all parts of the part are in full contact with the heat transfer oil and that the part is heated uniformly.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the reciprocating swaying mechanism includes a motor 201, which is fixedly connected in the transmission groove 103. The output end of the motor 201 is fixedly connected to a rotating disk 202. An adjustment module is provided on the rotating disk 202, and the adjustment module is connected to a limiting rod 203. A limiting groove 204 that cooperates with the limiting rod 203 is provided on the connecting plate 104. When the motor 201 is started, the motor 201 drives the rotating disk 202 to rotate, and the rotating disk 202 drives the upper limiting rod 203 to rotate. The limiting rod 203 slides in the limiting groove 204 of the connecting plate 104, driving the connecting plate 104 to reciprocate in the horizontal direction, thereby causing the heating basket 105 to sway.

[0027] In one embodiment, such as Figure 4 As shown, the adjustment module includes an adjustment frame 301, which is fixedly connected to the rotating disk 202. A threaded rod 302 is rotatably connected in the adjustment frame 301. The threaded rod 302 is driven by a motor 303, which is fixedly connected to the adjustment frame 301. The threaded rod 302 is threadedly connected to a moving block 304, which is slidably connected in the adjustment frame 301. The moving block 304 is fixedly connected to a limiting rod 203. If the sway amplitude needs to be adjusted, the controller 101 starts the motor 303, driving the threaded rod 302 to rotate. The moving block 304 moves the limiting rod 203 closer to or further away from the center of the rotating disk 202, thereby realizing the dynamic adjustment of the sway amplitude.

[0028] In one embodiment, such as Figure 3As shown, the lifting component includes two threaded rods 401, which are rotatably connected to a rotating frame on the connecting plate 104. Lifting sleeves 402 are threaded onto the threaded rods 401, and the two lifting sleeves 402 are fixedly connected to the heating basket 105. Four guide rods 403 are fixedly connected to the connecting plate 104, and the four guide rods 403 are slidably connected to the heating basket 105. A bevel gear 404 is fixedly connected to the two threaded rods 401, and the bevel gear 404 meshes with a bevel gear 405. The bevel gear 405 is fixed... Connected to the transmission rod 406, which is rotatably connected to the connecting plate 104, the transmission rod 406 is driven by the motor 407, which is fixedly connected to the connecting plate 104. The controller 101 controls the motor 407 to start, and the motor 407 drives the transmission rod 406 to rotate. Through the meshing of the bevel gear 404 and the bevel gear 405, the two threaded rods 401 are driven to rotate synchronously, thereby driving the lifting sleeve 402 to move. The lifting sleeve 402 drives the heating basket 105 to rise or fall along the guide rod 403 to complete the placement and removal of parts.

[0029] In one embodiment, such as Figure 2 As shown, the heating component includes a spiral electric heating tube 501, which is located in a heating tank 102. A partition 502 is provided at the upper end of the spiral electric heating tube 501 in the heating tank 102. The spiral electric heating tube 501 is electrically connected to a thermostat 504, which is electrically connected to a temperature sensor 503. The temperature sensor 503 is fixedly connected to the inner wall of the heating tank 102. The temperature sensor 503 monitors the temperature of the heat transfer oil in the heating tank 102 in real time and transmits the signal to the thermostat 504. When the oil temperature is lower than the set value, the thermostat 504 increases the power of the spiral electric heating tube 501. After the oil temperature reaches the set value, the thermostat 504 adjusts the power to maintain a constant temperature.

[0030] In one embodiment, such as Figure 1 As shown, the lower end of the housing 100 is fixedly connected to four casters 600 with brakes, which facilitates the movement of the equipment inside the workshop or laboratory. The braking function can ensure the stability of the equipment during operation and prevent displacement during shaking.

[0031] In one embodiment, such as Figure 2 As shown, a heat insulation layer 700 is provided on the housing 100 at the heating tank 102. The heat insulation layer 700 can effectively reduce the heat loss of the heating tank 102, reduce energy consumption, and at the same time prevent the outer wall temperature of the housing 100 from being too high, thus preventing the operator from being burned.

[0032] In one embodiment, such as Figure 1As shown, the two threaded rods 401 are symmetrically arranged on both sides of the housing 100 to ensure that the heating basket 105 is subjected to balanced force when it is raised and lowered, thus avoiding tilting.

[0033] The above embodiment discloses an oil bath type mechanical component heater, wherein the equipment is moved to a designated work position by the universal wheels 600 at the lower end, and the equipment is fixed by stepping on the brake; heat transfer oil is injected into the heating tank 102, and the temperature sensor 503 monitors the temperature of the heat transfer oil in the heating tank 102 in real time and transmits the signal to the temperature controller 504; when the oil temperature is lower than the set value, the temperature controller 504 increases the power of the spiral electric heating tube 501; after the oil temperature reaches the set value, the temperature controller 504 adjusts the power to maintain a constant temperature; the parts to be heated are placed in the heating basket 105, and the motor 3 407 drives the transmission rod 406 to rotate, and through the meshing transmission of the bevel gear 1 404 and the bevel gear 2 405, the two threaded rods 2 401 are driven to rotate synchronously. This causes the lifting sleeve 402 to move, and the lifting sleeve 402 causes the heating basket 105 to descend along the guide rod 403 to complete the placement of the parts. The motor 1 201 is started, and the motor 1 201 drives the rotating disk 202 to rotate. The rotating disk 202 drives the upper limit rod 203 to rotate. The limit rod 203 slides in the limit groove 204 of the connecting plate 104, driving the connecting plate 104 to move back and forth in the horizontal direction, thereby causing the heating basket 105 to shake, so that the parts are heated evenly. If it is necessary to adjust the shaking amplitude, the controller 101 starts the motor 2 303, drives the threaded rod 1 302 to rotate, and the moving block 304 drives the limit rod 203 to move closer to or away from the center of the rotating disk 202, so as to realize the dynamic adjustment of the shaking amplitude.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
