Description

Technical Field

[0001] The technical field of motor casing processing equipment of the present application particularly relates to a cooling system of motor casing processing equipment. Background Art

[0002] The motor case is a shell structure used to protect the core components of the motor. It is generally a cylindrical structure with one end open and the other end closed or semi-closed. The core components of the motor, such as the stator assembly and the rotor assembly, are installed in the cylindrical mounting cavity of the outer shell.

[0003] Generally, when making a motor housing, a series of operations such as milling, grinding and polishing are required. During the processing, the workpiece itself will generate a lot of heat due to long-term friction, which will affect the processing accuracy. Therefore, a circulating cooling system is generally set up on the processing equipment and the part in contact with the workpiece. However, in the case of long-term use, the coolant in the cooling pipe will also have impurities, which may affect the flow of the coolant and the cooling effect in the long run. Summary of the invention

[0004] In order to ensure a long-term stable coolant flow effect, the present application provides a cooling system for motor casing processing equipment.

[0005] A cooling system for motor casing processing equipment provided in the present application adopts the following technical solution: a cooling system for motor casing processing equipment, comprising a workbench and a clamping seat body for clamping the motor casing, a heat exchange channel being arranged in the clamping seat body, a friction ball being arranged to move in the heat exchange channel, and driving parts for driving the friction ball to move along the extension direction of the heat exchange channel being arranged at both ends of the heat exchange channel and on the clamping seat body.

[0006] By adopting the above technical solution, a friction ball is separately arranged in the heat exchange channel, and the friction ball can move in the heat exchange channel through the driving member. While moving, the impurities attached to the wall of the heat exchange pipe can be loosened or swept away, so that the impurities can fall off and be circulated and removed with the flow of the coolant, thereby forming a stable coolant flow effect.

[0007] Preferably, the friction ball is connected to a rigid rope, and the driving member is used to drag the rigid rope back and forth.

[0008] By adopting the above technical solution and setting the rigid rope, a more convenient dragging is achieved, and the rigid rope can be adapted to heat exchange channels of various shapes.

[0009] Preferably, the driving member comprises an exposed port arranged on the outer wall of the clamping seat body and a clamping driving wheel arranged between two exposed ports, and the clamping driving wheel is used to clamp the rigid rope.

[0010] By adopting the above technical solution, the clamping drive wheel will be clamped on the rigid rope. During its own rotation, the rigid rope will make a loop motion through friction, and the exposed port will form a corresponding sealing effect, so that the coolant will not overflow during the movement.

[0011] Preferably, the rigid rope has a hollow cavity therein, and the friction ball has a plurality of external expansion points within the cavity.

[0012] By adopting the above technical solution, when the clamping driving wheel squeezes the rigid rope, the chamber inside the friction ball will expand, so that the outer expansion point will bulge, forming a point that contacts the inner wall of the heat exchange channel, thereby forming a scraping effect.

[0013] Preferably, a receiving port which is not co-linear with the liquid flow channel is provided in the heat exchange channel for accommodating the friction ball.

[0014] By adopting the above technical solution, after dragging the outer wall, the friction ball can be hidden in the accommodation port to form a corresponding non-interference storage, so that the coolant will not be affected by the friction ball when flowing.

[0015] Preferably, the outer peripheral surface of the clamping drive wheel has a groove for the rigid rope to be embedded, and the groove has a plurality of protrusions for contacting the outer wall of the rigid rope.

[0016] By adopting the above technical solution, the presence of the protrusions can form better friction, and the grooves limit the position of the rigid rope to form better dragging force.

[0017] Preferably, the distance between the two clamping drive wheels is adjustable.

[0018] By adopting the above technical solution, on the one hand, it is used to control the force of squeezing the inner cavity of the friction ball, and on the other hand, it is also possible to adjust the resistance between the clamping drive wheel and the rigid rope.

[0019] Preferably, a driving block is provided on one side of the clamping driving wheel, and a moving part for driving the two driving blocks to approach each other is provided on the heat exchange channel.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: a friction ball is separately arranged in the heat exchange channel, and the friction ball can move in the heat exchange channel through a driving member. While moving, impurities attached to the wall of the heat exchange pipe can be loosened or swept away, so that the impurities can fall off and be circulated and removed with the flow of coolant, thereby forming a stable coolant flow effect.

Implementation

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The present application embodiment discloses a cooling system for a motor casing processing device, referring to Figure 1 , including a workbench 100 and a clamping seat body 110 for clamping a motor housing, a heat exchange channel 120 is arranged in the clamping seat body 110, and generally the heat exchange channel 120 is serpentine, a friction ball 121 is arranged in the heat exchange channel 120 for movement, and driving parts for driving the friction ball 121 to move along the extension direction of the heat exchange channel 120 are arranged at both ends of the heat exchange channel 120 and on the clamping seat body 110.

[0025] Reference Figure 1 , Figure 2 , the friction ball 121 is connected to a rigid rope 124, and the driving member is used to drag the rigid rope 124 back and forth. The rigid rope 124 is hollow in the middle and has a hollow cavity 125. The friction ball 121 also has an inner cavity 122 in the middle. The inner cavity 122 has multiple external expansion points 123, which are specifically, multiple parts with thinner wall thickness evenly distributed along the spherical surface. When the air pressure in the inner cavity 122 increases, the outer wall of the friction ball 121 has a convex part, which is used to abut against the inner wall of the heat exchange channel 120 to form a certain scraping effect. In this embodiment, the driving member includes an exposed port 130 arranged on the outer wall of the clamping seat 110, and a clamping drive wheel 131 arranged between the two exposed ports 130. The clamping drive wheel 131 is used to clamp the rigid rope 124. The rigid rope 124 is sealed and connected to the exposed port 130.

[0026] Reference Figure 2 , Figure 3The outer peripheral surface of the clamping driving wheel 131 has a groove 132 for the rigid rope 124 to be embedded, and the groove 132 has a plurality of protrusions 133 for contacting the outer wall of the rigid rope 124. The distance between the two clamping driving wheels 131 is adjustable, and a driving block 140 is provided on one side of the clamping driving wheel 131. A driving motor 141 is provided on the driving block 140, which is used to be connected to the rotating shaft of the clamping driving wheel 131 to drive it to rotate, and a moving part for driving the two driving blocks 140 to approach each other is provided on the heat exchange channel 120, so that the bottoms of the two corresponding grooves 132 are close to each other, thereby achieving extrusion and changing the pressure in the friction ball 121. On the one hand, it can be used to change the pressure of the outer expansion point 123 against the inner wall of the heat exchange channel 120, and on the other hand, it can be used to release or reduce the pressure in the friction ball 121, so that the outer expansion point 123 does not contact the inner wall of the heat exchange channel 120, which is convenient for the movement of the friction ball 121.

[0027] The moving part in this embodiment is a bidirectional threaded rod 142 driven to rotate by a motor, and its two ends are threaded in opposite directions and are respectively threadedly connected to the two driving blocks 140 to make the two driving blocks 140 approach or move away from each other.

[0028] At this time, in order to prevent the friction ball 121 from affecting the normal flow of the coolant after cleaning and scraping, a receiving port 150 that is not colinear with the liquid flow channel is provided in the heat exchange channel 120 for placing the friction ball 121. The "not colinear" mentioned here refers to not being colinear with the flow direction of the coolant. Specifically, in this embodiment, there is a broken path on one side of the external heat exchange channel 120, which serves as the above-mentioned receiving port 150. At the end of the movement, the friction ball 121 will enter the receiving port 150. Two receiving ports 150 can be provided, which can be located at both ends or only at one end.

[0029] In this embodiment, refer to Figure 1 During the movement of the friction ball 121, it is worth noting that since the connected driving part is the rigid rope 124, the rope itself may rotate circumferentially during the dragging process, which can prompt the friction ball 121 to move and scrape in different directions, and in the subsequent movement process, especially after the outer expansion point 123 retracts, the rigid rope 124 can also rely on itself to reset, which is more convenient and has a good cleaning effect.

[0030] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
