Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a cooling positioning tooling. Background Art

[0002] In the field of motor manufacturing, the machining quality of the motor rotor is directly related to the overall performance and reliability of the motor. In the production process of the motor rotor, in order to obtain better material properties and assembly accuracy, the rotor is often required to be heated and pressed. However, after heating and pressing, the surface temperature of the rotor is high and needs to be cooled quickly and effectively for subsequent processing.

[0003] Currently, the industry generally uses industrial fans and air coolers as the main heat dissipation equipment for cooling motor rotors after heating and pressing. Industrial fans take away the heat from the rotor surface by forced air convection, while air coolers generate low-temperature air through a refrigeration system, and then use the fan to blow the cold air to the rotor to achieve the purpose of cooling.

[0004] Although industrial fans and air coolers can meet the cooling needs of the rotor to a certain extent, the following problems still exist in actual applications: whether it is an industrial fan or an air cooler, a large amount of energy is wasted in lowering the ambient temperature during the cooling of the motor rotor, resulting in a large amount of energy consumption required for cooling. At the same time, the cooling range of a single industrial fan or air cooler is limited, and it is difficult to ensure that the heat is dissipated evenly and quickly. It is often necessary to set up multiple industrial fans or air coolers for cooling, which further increases the energy consumption required for cooling. Summary of the invention

[0005] The utility model aims to provide a cooling positioning tool to solve the problems existing in the prior art.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A cooling positioning tooling includes clamping tooling located on both sides of the product positioning tooling, the clamping tooling is located on a base plate, the clamping tooling includes a guide rail, a sliding platform, a driving mechanism and a contour floating mechanism, the sliding platform is slidably connected to the guide rail, the sliding platform is connected to the base plate through the driving mechanism, the contour floating mechanism includes a support frame, an elastic component and a cooling unit, the support frame is arranged on the sliding platform, the cooling units are arranged at intervals along the support frame, the cooling units are connected to the support frame through the elastic component, and the cooling units are connected through pipes.

[0008] The utility model clamps the motor rotor to be cooled by the contoured floating mechanism, dissipates heat from the surface of the rotor by the cooling unit surrounding the motor rotor, and performs heat exchange with the rotor surface by the coolant in the cooling unit, so that the heat on the rotor surface can be dissipated evenly and quickly. At the same time, since the temperature of the coolant is close to the ambient temperature, no condensed water is generated on the rotor surface.

[0009] The guide rail is used to limit the moving range of the sliding platform, and the elastic component is used to enable the cooling unit to move after contacting the rotor to avoid damage to the rotor. By adjusting the relative position of the sliding platform and the guide rail, the contoured floating mechanism can adapt to rotors of different sizes, thereby enabling the clamping tooling to be used for rotors of different sizes.

[0010] Preferably, the cooling unit includes a water inlet and a water outlet, the water inlet of the cooling unit at one end of the support frame is connected to the water circulation unit, and the water outlet of the cooling unit at the other end of the support frame is connected to the water circulation unit, and the water circulation unit fills coolant into the cooling unit through the water inlet.

[0011] The cooling unit is filled with coolant through the water circulation unit, and the coolant after heat exchange is recovered to achieve the recycling of the coolant, which reduces the energy consumption in the cooling process, improves the cooling efficiency, and ensures the cooling effect of the coolant.

[0012] Preferably, the support frame comprises a contour plate and a support plate, the contour plate is arranged around the product positioning tooling, adjacent contour plates are connected via the support plate, and the cooling unit is located between adjacent contour plates.

[0013] The contoured plate is arranged around the product positioning fixture, and can fit the rotor tightly, thereby ensuring effective contact between the cooling unit and the rotor surface.

[0014] Preferably, one side of the cooling unit is connected to the support plate via the elastic component, and the other side is used to contact the product on the product positioning tooling.

[0015] The cooling unit and the support plate are connected by the elastic component, allowing the cooling unit to have a certain floating and adaptive ability when contacting the rotor, which not only ensures the close contact between the cooling unit and the rotor surface, but also prevents the cooling unit from causing damage to the rotor.

[0016] Preferably, the guide rails are respectively located on both sides of the sliding platform, and the guide rails are arranged parallel to the moving direction of the sliding platform. When the clamping tooling contacts the product positioning tooling, the guide rails of adjacent clamping tooling contact each other.

[0017] The guide rail limits the moving range of the sliding platform. By adjusting the relative position of the guide rail and the sliding platform and adjusting the spacing between the sliding platforms, it is prevented that the clamping tooling collides with the rotor and damages the rotor.

[0018] Preferably, when the distance between adjacent clamping tools is the farthest, a feeding channel is left between the clamping tools, and the product positioning tool is moved into between the clamping tools through the feeding channel.

[0019] When the feeding channel is formed, the product positioning tool can be moved into or out of the clamping tool through the feeding channel.

[0020] Preferably, a positioning mechanism is provided on the sliding platform, and the positioning mechanism comprises a base and a guide rod, the base and the guide rod are slidably connected, and the sliding platform is connected to the product positioning tooling through the guide rod.

[0022] Preferably, the driving mechanism comprises a limiting rod and a push rod, the sliding platform is slidably connected to the limiting rod, and the push rod pushes the sliding platform to move along the limiting rod.

[0023] The limiting rod limits the moving path of the sliding platform, and the pushing rod pushes the sliding platform to move along the limiting rod, so that the sliding platform approaches or moves away from the product positioning tool.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] (1) The utility model clamps the motor rotor to be cooled by a contoured floating mechanism, dissipates heat from the surface of the rotor by a cooling unit surrounding the motor rotor, and exchanges heat with the rotor surface through the coolant in the cooling unit, so that the heat on the rotor surface can be dissipated evenly and quickly. At the same time, since the temperature of the coolant is close to the ambient temperature, no condensed water will be generated on the rotor surface.

[0026] (2) In the utility model, a guide rail is used to limit the moving range of the sliding platform, and an elastic component is used to enable the cooling unit to move after contacting the rotor to avoid damage to the rotor. By adjusting the relative position of the sliding platform and the guide rail, the contoured floating mechanism can adapt to rotors of different sizes, thereby enabling the clamping tooling to be used for rotors of different sizes.

[0032] like Figure 1~2 As shown, the specific scheme of the embodiment is as follows: a cooling positioning tool is applied to the production line of the motor rotor 1, the motor rotor 1 is placed on the product positioning tool 2, and the production line adopts a ring conveying mechanism to move the product positioning tool 2 to each station.

[0033] A cooling positioning tool comprises clamping tools located on both sides of a product positioning tool 2. When a motor rotor 1 has not reached a cooling station, the distance between adjacent clamping tools is the farthest. A feeding channel is left between the clamping tools. After the motor rotor 1 is heated and pressed, it is moved between the clamping tools through the feeding channel.

[0034] The clamping tool is located on the bottom plate of the annular conveying mechanism. The clamping tool comprises a guide rail 3, a sliding platform 4, a driving mechanism 5 and a contour-profiling floating mechanism. The sliding platform 4 is connected to the bottom plate through the driving mechanism 5.

[0035] The driving mechanism 5 includes a limit rod, a push rod and a clamping cylinder 501. The limit rod and the push rod are respectively fixed to the bottom plate of the annular conveying mechanism through ear plates. The clamping cylinder 501 is arranged at the bottom of any sliding platform 4. The sliding platform 4 is slidably connected to the limit rod, and the sliding platform 4 is connected to the push rod. The push rod pushes the sliding platform 4 to move along the limit rod. The push rod adopts a pneumatic push rod, and the clamping cylinder 501 controls the movement of the push rod.

[0036] The guide rails 3 are respectively located on both sides of the sliding platform 4, and the guide rails 3 are set parallel to the moving direction of the sliding platform 4. The sliding platform 4 is slidably connected to the guide rails 3 through the slider, and the slider is sleeved on the guide rails 3. The guide rails 3 of adjacent clamping tooling are parallel to each other. Positioning holes are respectively provided on the guide rails 3 and the slider. When the relative position of the guide rails 3 and the sliding platform 4 needs to be fixed, bolts or positioning pins are used to pass through the positioning holes to connect the guide rails 3 and the slider.

[0037] The sliding platform 4 is provided with a support rod and a positioning mechanism 6 on the side away from the guide rail 3. The support rods are arranged in parallel. The positioning mechanism 6 is located between the support rods. The positioning mechanism 6 includes a base and a guide rod. The base is arranged on the sliding platform 4. The base and the guide rod are slidably connected. The guide rod is used to be inserted into the positioning hole of the product positioning tooling 2. The sliding platform 4 is connected to the product positioning tooling 2 through the guide rod.

[0038] The contour floating mechanism includes a support frame 7, an elastic component 8 and a cooling unit 9. The support frame 7 includes a contour plate and a support plate. The contour plate is an arc-shaped plate. The contour plate is arranged around the product positioning tooling 2. Adjacent contour plates are connected by the support plate. The contour plate is connected to the sliding platform 4 through a support rod. The cooling unit 9 is located between adjacent contour plates.

[0039] The cooling units 9 are arranged at intervals along the contoured plates of the support frame 7. One side of the cooling units 9 is connected to the support plate through an elastic component 8, and the other side is used to contact the product on the product positioning fixture 2. The elastic component 8 adopts a spring.

[0040] The cooling unit 9 includes a water inlet, a water outlet, a return pipe and a heat conductive block. A water circulation cavity is provided in the heat conductive block. The water circulation cavities are arranged in parallel. The water inlet and the water outlet are located at the top of the heat conductive block.

The water circulation cavities are connected through the return pipe, and adjacent heat conductive blocks are connected through pipelines.

[0041] The water inlet of the cooling unit 9 at one end of the support frame 7 is connected to the water circulation unit, and the water outlet of the cooling unit 9 at the other end of the support frame 7 is connected to the water circulation unit. The water circulation unit fills the cooling unit 9 with coolant through the water inlet, and the coolant returns to the water circulation unit from the water outlet of the cooling unit 9.

[0042] The water circulation unit includes a water reservoir and a cooling system. The cooling system is used to reduce the temperature of the coolant in the water reservoir to improve the heat exchange capacity of the cooling unit 9.

[0043] The working principle of this embodiment is as follows: when the distance between adjacent clamping fixtures is at its farthest, the product positioning fixture 2 is moved between the clamping fixtures through the annular conveying mechanism, and the driving mechanism 5 pushes the sliding platforms 4 to approach each other until the guide rails 3 of the adjacent clamping fixtures contact each other. At this time, the sliding platform 4 is connected to the product positioning fixture 2 through the positioning mechanism 6, and the cooling unit 9 of the contoured floating mechanism contacts the motor rotor 1 to reduce the temperature of the motor rotor 1. After the cooling of the motor rotor 1 is completed, the driving mechanism 5 drives the sliding platforms 4 to move away from each other until a feeding channel is left between the clamping fixtures, and the product positioning fixture 2 is moved out through the annular conveying mechanism, waiting for the arrival of the next motor rotor 1.
