Description

Technical Field

[0001] This utility model belongs to the field of motor housing processing technology, and relates to a constant temperature mechanism for motor housing processing. Background Technology

[0002] The motor housing is an important component of the motor. It encapsulates the motor's internal parts, effectively protecting them.

[0003] In order to ensure the structural strength of the motor housing during the production and processing, the motor housing needs to be quenched. The heat treatment process of the motor housing generally includes multiple steps such as material preparation, heating, heat preservation, and cooling. In the heat preservation step, the traditional method is to use an insulation box for heat preservation. Traditional heat preservation only heats the outside of the motor housing, which can easily cause the internal temperature of the motor housing to be different from the external temperature, affecting the heat preservation effect.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-4 As shown, this utility model discloses a constant temperature mechanism for processing motor housings, including a worktable 1. A constant temperature chamber 2 is fixedly installed on the top of the worktable 1. An adjustable inner heating column 7 is provided at the top of the interior of the constant temperature chamber 2. An outer heating sleeve 12 is fixedly provided at the bottom of the interior of the constant temperature chamber 2. The size of the outer heating sleeve 12 is larger than the outer diameter of the motor housing, and the size of the inner heating column 7 is smaller than the inner diameter of the motor housing. A movable crossbar 11 is provided on one side of the constant temperature chamber 2. A motor housing clamping assembly is fixedly installed at the end of the crossbar 11 for picking up and putting down the motor housing.

[0019] Specifically, this constant temperature mechanism ensures that the surface temperature of the motor housing remains constant during the quenching and heat preservation process by placing the motor housing inside the outer heating jacket 12 and inserting the inner heating column 7 into the interior of the motor housing through synchronous heating inside and outside, thus ensuring the heat preservation effect of the motor housing.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a constant temperature mechanism for processing motor housings. A first electric push rod 5 is fixedly installed at the center of the top of the inner end of the constant temperature chamber 2. An upper fixing plate 6 is fixedly installed at the telescopic end of the first electric push rod 5. The center of the bottom end of the upper fixing plate 6 is fixedly connected to the top end of the inner heating column 7.

[0021] Multiple heating strips 13 are fixedly arranged at equal intervals inside the outer heating sleeve 12, and the multiple heating strips 13 are located between two adjacent heat dissipation fins of the motor housing.

[0022] Specifically, by setting heating strip 13, which is located between the heat dissipation fins of the motor housing, the heat dissipation of the insulated motor housing is further ensured to be heated evenly.

[0023] A vertical electric slide rail 9 is fixedly installed on one side of the inner wall of the constant temperature chamber 2. A first slide block 14 is slidably connected to the surface of the vertical electric slide rail 9. A horizontal electric slide rail 10 is fixedly installed on the front of the first slide block 14. A second slide block 15 is slidably connected to the surface of the horizontal electric slide rail 10. The front of the second slide block 15 is fixedly connected to the other end of the crossbar 11.

[0024] Specifically, through the cooperation of the vertical electric slide rail 9 and the horizontal electric slide rail 10, the first slide block 14 moves vertically and the second slide block 15 moves horizontally, which enables the clamped motor housing to move vertically and horizontally, ensuring that the motor housing is moved into the interior of the outer heating sleeve 12.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a constant temperature mechanism for processing motor housings. The motor housing clamping assembly includes a fixing ring 16, a carbon ceramic clamping block 17, and a second electric push rod 18. One side of the fixing ring 16 is fixedly connected to the end of the crossbar 11. The second electric push rod 18 is fixedly installed on both sides of the inner wall of the fixing ring 16. The telescopic ends of the two second electric push rods 18 are fixedly installed with carbon ceramic clamping blocks 17.

[0026] Specifically, the carbon ceramic clamping block 17 is moved by the second electric push rod 18, and the motor housing is clamped by the carbon ceramic clamping block 17, which improves the stability of the motor housing movement during the process of picking up and putting down the motor housing.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a constant temperature mechanism for processing motor housings. A temperature sensor 8 is fixedly installed on the other side of the inner wall of the constant temperature chamber 2. A door 3 is hinged to one side of the front of the constant temperature chamber 2. A handle 4 is fixedly installed on one side of the front of the door 3. A PLC controller is fixedly installed on the front of the door 3. The temperature sensor 8, the inner heating column 7, the outer heating sleeve 12, the first electric push rod 5, the second electric push rod 18, the vertical electric slide rail 9, and the horizontal electric slide rail 10 are all electrically connected to the PLC controller.

[0028] Specifically, the operation of electrical equipment is controlled through a PLC controller.

[0029] In specific implementation, when using this constant temperature mechanism to heat-insulate the quenched motor housing, first turn on the power and open the box door 3. Nest the fixing ring 16 with the top of the motor housing and open the second electric push rod 18. The second electric push rod 18 pushes the carbon ceramic clamping block 17 to clamp the motor housing. Then, manually operate the PLC controller (model "S7-1500") to control the stroke of the vertical electric slide rail 9 and the horizontal electric slide rail 10 to place the motor housing to be heat-insulated into the interior of the outer heating sleeve 12. Next, open the first electric push rod 5 to push the inner heating column 7 into the interior of the motor housing. Then, energize and heat the heating wires inside the outer heating sleeve 12 and the inner heating column 7. During the heat preservation process, the temperature sensor 8 monitors the temperature in real time to ensure that the heat preservation temperature is within the set range.

[0030] It should be noted that the temperature sensor 8, inner heating column 7, outer heating sleeve 12, first electric push rod 5, second electric push rod 18, vertical electric slide rail 9 and horizontal electric slide rail 10 used in this application are all commercially available devices known to those skilled in the art.
