Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts production, and particularly relates to an inner cavity protection device for torque converter housing spraying. Background Art

[0002] A torque converter is a device used to change rotational torque or transmit power. The torque converter can adjust the input and output speed and torque to meet the needs of different working conditions. Its application in automobiles is particularly important, allowing the engine to maintain efficient operation in different speed ranges and provide smooth acceleration and deceleration processes.

[0003] The torque converter housing is usually used to wrap and protect the internal parts of the torque converter. When the torque converter housing is produced and painted, its inner surface cannot be contaminated with paint and needs to be sealed with external protective parts for isolation and protection. However, the external protective parts are easily detached from the torque converter housing during the painting process, causing paint to enter the inner cavity of the torque converter housing and affect the production of the torque converter housing. Utility Model Content

[0004] The utility model aims to solve the problem that the external protective member in the prior art is easy to be separated from the torque converter housing during the painting process, and proposes the following technical solutions:

[0005] An inner cavity protection device for spraying a torque converter housing comprises: a housing and a closing table, a rubber layer is provided on the surface of the closing table, a stabilizing component is provided inside the closing table, the stabilizing component comprises a screw rod, oppositely arranged threads are provided on the surfaces of both ends of the screw rod, sliders are threadedly sleeved on the threaded surfaces at both ends of the screw rod, a pushing block is fixedly connected to one end of the slider, a gear is fixedly connected to the middle part of the screw rod, a rack is meshedly connected to one side of the gear, a bolt is rotatably sleeved on the top of the rack, and a section of the bolt surface is threadedly sleeved on the closing table.

[0006] As a preferred embodiment of the above technical solution, the stabilizing component also includes a stabilizing part, which includes a driven plate, and multiple stabilizing blocks are arranged on both sides of the driven plate. The stabilizing blocks are movably inserted in the side walls of the closed platform, and an elastic ring is sleeved on the surface of the stabilizing blocks.

[0007] As a preferred embodiment of the above technical solution, the stabilizing component further includes a limiting plate, the slider and the rack are both movably inserted in the limiting plate, and the limiting plate is fixedly connected to the closing platform.

[0008] As a preferred embodiment of the above technical solution, the elastic ring is hollow, and two ends of the elastic ring are fixedly connected to the stabilizing block and the inner wall surface of the closing platform respectively.

[0009] The beneficial effects of the utility model are:

[0010] 1. The set stabilizing component can fix the closing table inside the shell to prevent it from detaching from the torque converter shell during the painting process, which will not affect the production of the torque converter shell. At the same time, the fixed closing table can be quickly released through the stabilizing component, making it more convenient to remove the closing table;

[0011] 2. The movement of the push block drives the driven plate to move. When the driven plate contacts the stabilizing block, the rubber layer is pushed to deform. The deformed rubber layer squeezes the inner surface of the shell to increase the static friction with the inner surface of the shell, further increasing the stability of the closing platform and the shell.

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings of the specification.

[0017] Example

[0018] Figure 1-Figure 3 In the figure, the inner cavity protection device for spraying the torque converter housing 10 includes: a housing 10 and a closed platform 20, a rubber layer 40 is provided on the surface of the closed platform 20, a stabilizing component 30 is provided inside the closed platform 20, and the stabilizing component 30 includes a screw rod 31, and the surfaces of both ends of the screw rod 31 are provided with reversely arranged threads, and the threaded surfaces at both ends of the screw rod 31 are threadedly sleeved with sliders 32, one end of the slider 32 is fixedly connected to a pushing block 33, the middle part of the screw rod 31 is fixedly connected to a gear 34, one side of the gear 34 is meshedly connected to a rack 35, the top of the rack 35 is rotatably sleeved with a bolt 36, and a section of the surface of the bolt 36 is threadedly sleeved with the closed platform 20.

[0019] When the inner cavity of the shell 10 is closed, the closing platform 20 is installed into the inner cavity of the shell 10, and the rubber layer 40 closes the inner cavity of the shell 10. Then, the bolt 36 is rotated to drive the rack 35 to move downward, and the gear 34 drives the screw rod 31 to rotate. The two sliders 32 drive the corresponding pushing blocks 33 to move in the opposite direction. The pushing blocks 33 are inserted into the opening of the shell 10 and push the rubber layer 40 to deform, so that the opening of the shell 10 can be closed and the closing platform 20 can be fixed at the same time.

[0020] By setting up the stabilizing component 30, the closing table 20 can be fixed inside the shell 10 to prevent it from detaching from the torque converter shell 10 during the painting process, which will not affect the production of the torque converter shell 10. At the same time, the stabilizing component 30 can quickly release the fixed closing table 20, making it more convenient to remove the closing table 20.

[0021] Figure 2-Figure 3 In the figure, the stabilizing component 30 also includes a stabilizing portion 37, which includes a driven plate 371. A plurality of stabilizing blocks 372 are provided on both sides of the driven plate 371. The stabilizing blocks 372 are movably inserted into the side walls of the closed platform 20, and an elastic ring 373 is sleeved on the surface of the stabilizing blocks 372.

[0022] During the movement of the pushing block 33, the driven plate 371 moves accordingly and contacts with the multiple stabilizing blocks 372 on both sides at the same time. The stabilizing block 372 is partially pushed by the driven plate 371 to deform the rubber layer 40. The deformed rubber layer 40 squeezes the inner surface of the shell 10, and the elastic ring 373 is compressed and deformed accordingly. When the pushing block 33 is reset, the elastic ring 373 in a compressed state drives the stabilizing block 372 to reset, and the rubber layer 40 is reset accordingly and no longer squeezes the inner surface of the shell 10.

[0023] The movement of the pushing block 33 drives the driven plate 371 to move. When the driven plate 371 contacts the stabilizing block 372, the rubber layer 40 is pushed to deform. The deformed rubber layer 40 squeezes the inner surface of the shell 10 to increase the static friction with the inner surface of the shell 10, further increasing the stability of the closing platform 20 and the shell 10.

[0024] Figure 2 In the embodiment, the stabilizing assembly 30 further includes a limiting plate 38 , and the slider 32 and the rack 35 are both movably inserted in the limiting plate 38 , and the limiting plate 38 is fixedly connected to the closing platform 20 .

[0025] The limiting plate 38 is used to limit the slider 32 and the rack 35 to prevent the screw rod 31 from rotating and driving the slider 32 to rotate.

[0026] Figure 3In the embodiment, the elastic ring 373 is hollow, and two ends of the elastic ring 373 are fixedly connected to the stabilizing block 372 and the inner wall surface of the closing platform 20 respectively.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
