Description

Technical Field

[0001] This utility model relates to the field of heat treatment forming fixtures, and in particular to heat treatment fixtures for thrust bearing washers. Background Technology

[0002] The washers in the thrust bearing require tempering heat treatment; see [link / reference]. Figure 4 This is a schematic diagram of a conventional heat treatment structure. The mandrel 01 extends radially outwards and is provided with a fan-shaped positioning element 02 (see...). Figure 5 In this way, the inner wall of the pressure ring contacts the arc-shaped outer wall of the positioning element, achieving radial internal positioning of the pressure ring. After the pressure ring and the gasket between the pressure rings are pressed together by the support seat and the pressure cover, subsequent tempering treatment is performed. However, the presence of the positioning element makes the overall heat treatment tooling too heavy and inconvenient to handle. In addition, since the positioning element and the pressure ring are internally positioned, when the size of the pressure ring changes with the gasket, another type of tooling is required for positioning. Therefore, this tooling is not universal.

[0003] In addition, traditional tooling often results in nuts that cannot be easily removed after long-term use, making it impossible to remove the gland for regular re-grinding. If the total height of the pressure ring and washer is lower than the height of the upper and lower planes of the positioning part 02, the washer cannot be fully compressed, which can lead to washer warping problems.

[0004] In addition, the upper and lower surfaces of the traditional positioning component 02 are flat. When the support base and the pressure cap are in full contact with the upper and lower surfaces of the positioning component 02, if the total height of the pressure ring and the washer is lower than the height of the upper and lower planes of the positioning component, the washer will not be able to be fully compressed, which will lead to the problem of washer warping.

[0005] In summary, reducing tooling weight, improving tooling versatility, enhancing the stability of product quality after shaping, and improving tooling reliability and ease of maintenance have become urgent problems for researchers in this field. Utility Model Content

[0006] The technical problem to be solved by this utility model is: how to reduce the weight of the tooling, improve the versatility of the tooling, improve the stability of the product quality after shaping, and improve the reliability and ease of maintenance of the tooling.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model relates to a heat treatment fixture for thrust bearing washers, comprising: a base; two actuators disposed opposite to each other on the base; a push plate connected to the output end of the corresponding actuator; a support seat disposed between the two push plates; multiple pressure rings axially disposed on the support seat, with washers disposed between adjacent pressure rings; a pressure cap disposed on top of the top pressure ring; and a screw, with clamping members disposed at both ends of the screw; connecting one end of the screw to the clamping members, and then longitudinally inserting the screw... A support base is formed, on which the pressure ring and washer are stacked in sequence. The pressure cap is placed on the topmost pressure ring and pre-tightened by connecting it to the screw via another clamping member. The pressure ring, pressure cap, and support base are then placed on the base. The two actuating components drive the two push plates to move closer to each other and act on the outer walls of the pressure ring, pressure cap, and support base. The axes of the pressure ring and pressure cap are adjusted to be collinear with the axis of the support base. Finally, the clamping member at the top of the screw is tightened to press the pressure ring and washer between the support base and the pressure cap.

[0009] Furthermore, the clamping component is a nut that mates with the screw.

[0010] Furthermore, the actuating component includes: a bracket, the bottom of which is connected to the base; and a cylinder, which is horizontally connected to the bracket.

[0011] Furthermore, a V-shaped groove is provided on one side of the push plate near the pressure ring.

[0012] Furthermore, annular grooves are formed on both the upper and lower surfaces of the pressure rings, and two washers are provided between two adjacent pressure rings. The two washers are arranged opposite to each other, and the vertical wall of the washer is located in the corresponding annular groove.

[0013] The beneficial effects of this utility model are as follows: This utility model is a heat treatment fixture for thrust bearing washers. Unlike mandrels with positioning elements, the screw in this embodiment is a standard part, which reduces the overall weight and cost of the fixture while also facilitating subsequent screw replacement. Furthermore, unlike traditional inner diameter positioning, this embodiment uses outer diameter positioning for the pressure ring, support seat, and pressure cap. This allows for the positioning of pressure rings, support seats, and pressure caps of different diameters, thereby achieving the clamping of washers of different diameters and improving the versatility of the fixture. Also, since this fixture does not use positioning elements... The screw in this fixture uses a mandrel-like design, so it only serves a connecting function and does not provide positioning. This avoids the problem of washer warping due to insufficient tightening, thus improving the stability of product quality. Furthermore, because this fixture uses a screw-clamping mechanism, unlike traditional fixtures where interference from positioning components requires disassembling both nuts from the mandrel before grinding the gland, this fixture allows the screw to be pulled out from the other side when one screw wears down. This enables grinding of the support and gland, improving the convenience of fixture maintenance. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] See Figure 1 , Figure 2 In the figure, the base 1 is placed horizontally on the workbench. One actuator 2 is located on the left side of the base 1, and the other actuator 2 is located on the right side of the base 1. The output ends of the two actuator 2 are opposite to each other and are set horizontally. Two push plates 3 are respectively connected to the output ends of the corresponding actuator 2. The support base 4 is placed between the two push plates 3 and is located in the positioning hole on the base 1. The pressure ring 5 is set on the support base 4 along the axial direction of the support base 4. A washer 6 that needs to be heat-treated is set between two adjacent pressure rings 4. The pressure cover 7 is set on the top of the topmost pressure ring 5.

[0022] In this embodiment, one end of the screw 8 is connected to the clamping member 9, and then it is installed longitudinally from bottom to top into the support base 4. The pressure ring 5 and the washer 6 are stacked on the support base 4 in sequence. The pressure cover 7 is placed on the topmost pressure ring 5. The screw 8 is pre-tightened by connecting it to another clamping member 9. The pressure ring 5, the pressure cover 7, and the support base 4 are placed on the base 1. The two actuators 2 drive the two push plates 3 to move closer to each other and act on the outer wall of the pressure ring 5, the pressure cover 7, and the support base 4. The axis of the pressure ring 5 and the pressure cover 7 is adjusted to be collinear with the axis of the support base 4. Finally, the clamping member 9 at the top of the screw 8 is tightened to press the pressure ring 5 and the washer 6 between the support base 4 and the pressure cover 7.

[0023] Unlike the spindle 01 with positioning element 02, the screw 8 in this embodiment is a standard part, which reduces the overall weight of the tooling and facilitates the replacement of the screw 8 later. In addition, unlike the traditional inner diameter positioning method, this embodiment adopts outer diameter positioning for the pressure ring 5, support seat 4, and pressure cap 7. This allows for the positioning of pressure rings 5, support seats 4, and pressure caps 7 with different diameters, thereby achieving the clamping of washers 6 with different diameters and improving the versatility of the tooling.

[0024] In addition, only disassembly is required. Figure 2 The upper or lower clamping part allows the screw 8 to be pulled out longitudinally from the top or bottom and separated from the pressure cover 7 and support seat 4, which facilitates the subsequent grinding and repair of the pressure cover 7 and support seat 4.

[0025] In some possible embodiments, see Figure 1 The clamping part 9 uses a nut that mates with the screw 8.

[0026] In some possible embodiments, see Figure 1 The execution component 2 includes: a bracket 21 and a cylinder 22; the bottom of the bracket 21 is connected to the base 1; the cylinder 22 is horizontally connected to the bracket 21.

[0027] In this embodiment, the cylinder 22 is connected to the base 1 by a bracket 21, so that the two cylinders 22 are horizontal and opposite to each other.

[0028] In some possible embodiments, see Figure 1 A V-shaped groove 31 is provided on one side of the push plate 3 near the pressure ring 5;

[0029] In this embodiment, by setting the V-groove 31 to increase the contact point with the outer wall of the pressure ring 5, support seat 4, and pressure cover 7, the push plate 3 can be radially pushed by the pressure ring 5, support seat 4, and pressure cover 7.

[0030] In some possible embodiments, see Figure 3 The upper and lower surfaces of the pressure ring 5 are provided with annular grooves 51. Two washers 6 are provided between two adjacent pressure rings 5. The two washers 6 are arranged back to back, and the vertical wall 61 of the washers 6 is located in the corresponding annular groove 51.

[0031] In this embodiment, the washers 6 are arranged vertically and opposite to each other. The vertical wall 61 of the upper washer 6 is located in the bottom annular groove 51 of the upper pressure ring 5, and the vertical wall 61 of the lower washer 6 is located in the top annular groove 51 of the lower pressure ring 5. This achieves the positioning of the two adjacent pressure rings 5 ​​and the two washers 6.
