Description

Technical Field

[0001] This utility model relates to the field of thermal management technology, and in particular to a workpiece tooling for automobiles. Background Technology

[0002] During production and transportation, tooling is needed to support workpieces. For example, cold-rolled steel sheets need to be stacked during production. During stacking, a layer of bubble wrap needs to be placed after each layer of cold-rolled steel sheet to prevent direct contact between adjacent cold-rolled steel sheets and avoid damage to their surfaces. Therefore, a step of removing the bubble wrap needs to be added to the production line, which increases process costs and production cycle time. Utility Model Content

[0003] Therefore, it is necessary to provide a workpiece tooling to address the above problems.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A workpiece fixture includes a placement area and at least one support structure. The support structure includes a plurality of support members and a housing extending in a first direction. The extension direction of the housing is defined as a first direction. Along the first direction, the plurality of support members are spaced apart. Along the first direction, the distance between adjacent support members is greater than the thickness of the workpiece. Each support member includes a support portion. At least a portion of the support member includes a first working state in which the support portion is outside the placement area. The support member also includes a second working state in which at least a portion of the support portion is inside the placement area.

[0006] In the above technical solution, in the first working state, the support part is outside the placement area and does not support the workpiece. The workpiece can move along the first direction. In the second working state, at least part of the support part is inside the placement area. Therefore, the part of the support part inside the placement area can support the workpiece. Since multiple support parts are spaced apart along the first direction, multiple workpieces are stacked along the first direction. Because multiple support parts are spaced apart, adjacent workpieces do not contact each other, thereby reducing the probability of damage to the workpiece surface. Moreover, compared with using bubble wrap to separate adjacent workpieces, the above technical solution reduces the process of picking up bubble wrap and reduces the production cycle.

Specific implementation

[0027] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following is combined with the drawing and technical scheme, and the utility model is further described in detail. It should be understood that the specific technical scheme described here is only used to explain the utility model, and is not used to limit the utility model.

[0028] Please refer to Figures 1-18 , Figure 1The utility model provides a workpiece frock, including placing area 300 and at least one support structure 12, the workpiece in this scheme is with cold plate 10 as an example, cold plate 10 is placed in placing area 300, and support structure 12 includes a plurality of support 122, and support structure 12 plays the role of supporting cold plate 10, and support structure 12 includes the casing 123, and the casing 123 extends along a direction, and the extension direction of casing 123 is defined as the first direction, along the first direction, a plurality of support 122 are arranged at intervals, and each support 122 can support a cold plate 10, and therefore along the first direction, support structure 12 can support a plurality of cold plates 10, along the first direction, the spacing between adjacent support 122 is greater than the thickness of workpiece, that is, the spacing between adjacent support 122 is greater than the thickness of cold plate, and therefore a plurality of cold plates 10 are stacked in the first direction of workpiece frock, and adjacent cold plates 10 do not contact, thereby reducing the probability of damage on the surface of cold plate 10, and support 122 includes support part 1221, and at least part support 122 includes first working state, under first working state: support part 1221 is outside placing area 300, because support part 1221 is outside placing area 300, and cold plate 10 is placed in placing area 300, therefore support part 1221 does not play the role of supporting cold plate 10, and support part 1221 will not block cold plate 10 and moves along the first direction, and cold plate 10 can move along the first direction, and support 122 includes second working state, under second working state: at least part support part 1221 is in placing area 300, because at least part support part 1221 is in placing area 300, and cold plate 10 is placed in placing area 300, therefore support part 1221 plays the role of supporting cold plate 10.

[0029] Further, the plurality of support structures 12 are arranged along the circumferential side of the placement area 300, the shell 123 comprises a first mounting portion 121, the support 122 comprises a connecting portion 1222, the connecting portion 1222 is rotationally connected with the first mounting portion 121, and the support portion 1221 is fixedly connected with the connecting portion 1222. It should be noted that in the present scheme, the first mounting portion 121 and the shell 123 are in one-piece structure, specifically, the first mounting portion 121 is the part of the shell 123 connected with the connecting portion 1222. In other embodiments, the first mounting portion 121 and the shell 123 can also be in split structure, the first mounting portion 121 is first connected with the wall portion of the shell 123, and then the connecting portion 1222 is connected with the first mounting portion 121. Since the connecting portion 1222 is rotationally connected with the first mounting portion 121, and the support portion 1221 is fixedly connected with the connecting portion 1222, the support portion 1221 is rotationally connected with the first mounting portion 121. In the second working state, the support portion 1221 is closer to the placement area 300 than the connecting portion 1222 and the connecting portion of the first mounting portion 121 in the direction from the first mounting portion 121 to the placement area 300. Since in the first working state, the support portion 1221 is located outside the placement area 300, and in the second working state, the support portion 1221 is located inside the placement area 300, the rotationally connecting the connecting portion 1222 with the first mounting portion 121 enables the support 122 to change from the first working state to the second working state or from the second working state to the first working state.

[0030] Referring to Figures 1-13In this embodiment, the connecting portion 1222 extends in a direction, the extending direction of the connecting portion 1222 is defined as a second direction, the support member 122 includes a counterweight portion 1223, along the second direction, the support portion 1221 is located at one side of the connecting portion 1222 and the first mounting portion 121, and the counterweight portion 1223 is located at the other side of the connecting portion 1222 and the first mounting portion 121, because the connecting portion 1222 is rotationally connected with the first mounting portion 121, and the support portion 1221 and the counterweight portion 1223 are respectively located at both ends of the connecting portion 1222 along the first direction, therefore the support portion 1221 and the counterweight portion 1223 can rotate with the connecting portion 1222 and the first mounting portion 121 as the rotation center, along the first direction, one side end of the shell 123 is defined as a first end 1231, in the first working state: along the first direction, the support portion 1221 is farther away from the first end 1231 than the connecting portion 1222, and the counterweight portion 1223 is closer to the first end 1231 than the connecting portion 1222, along the direction from the first mounting portion 121 to the placement area 300, the connecting portion 1222 is closer to the placement area 300 than the counterweight portion 1223, therefore along the first direction, the counterweight portion 1223 has a tendency to rotate towards the first end 1231, and the support portion 1221 has a tendency to rotate away from the first end 1231, the support portion 1221 abuts against the adjacent support member 122 away from the first end 1231, and the support portion 1221 is limited to rotate away from the first end 1231 by the adjacent support portion 1221 away from the first end 1231.

[0031] Further, in this scheme, the connecting portion 1222 has an avoiding portion 12221, and the connecting portion 1222 includes an abutting portion 12222, in the first working state: the support portion 1221 is at least partially located in the adjacent avoiding portion 12221 away from the first end 1231, the abutting portion 12222 abuts against the adjacent connecting portion 1222 away from the first end 1231, and the abutting portion 12222 limits the adjacent support portion 1221 close to the first end 1231 to rotate away from the bottom plate 112.

[0032] In the embodiment, in the first direction, one side end of the shell 123 is defined as a first end 1231, and the support 122 includes a positioning portion 1224 fixedly connected with the wall portion of the first mounting portion 121. In the second working state: the wall portion of the support 1221 close to the first end 1231 abuts against the positioning portion 1224, and the positioning portion 1224 limits the rotation of the support 1221 in the direction close to the first end 1231. Since in the second working state: the support 1221 is located in the placement area 300, the support 1221 plays a supporting role on the cold plate 10, and after the cold plate 10 is placed on the support 1221, the cold plate 10 has a tendency to drive the support 1221 to rotate in the direction close to the first end 1231. The wall portion of the support 1221 close to the first end 1231 abuts against the positioning portion 1224, the positioning portion 1224 limits the rotation of the support 1221 in the direction close to the first end 1231, and thus the cold plate 10 can be placed on the support 1221.

[0033] Referring to Figures 7-13In the embodiment, the support 122 comprises a third working state, the tooling comprises a second mounting portion 400, the second mounting portion 400 is fixedly connected with the first end portion 1231 of the shell 123, and in the third working state, for the support 122 closest to the second mounting portion 400 in the first direction: the support portion 1221 is at least partially located in the placement area 300, the support portion 1221 is not in contact with the positioning portion 1224, the counterweight portion 1223 of the support 122 is in abutment with the second mounting portion 400 in the first direction, and because the second mounting portion 400 is fixedly connected with the first end portion 1231 of the shell 123, the counterweight portion 1223 has a tendency to rotate towards the second mounting portion 400, so that the counterweight portion 1223 is in abutment with the second mounting portion 400, the rotation of the counterweight portion 1223 towards the second mounting portion 400 is limited, and the at least partial location of the support portion 1221 in the placement area 300 is further caused. Because the at least partial location of the support portion 1221 in the placement area 300, the cold plate 10 moves in the first direction in the placement area 300 to the direction close to the second mounting portion 400, the wall portion of the cold plate 10 close to the second mounting portion 400 is in abutment with the portion of the support portion 1221 located in the placement area 300, and the support portion 1221 is driven to rotate to the direction close to the second mounting portion 400, so that the support 122 changes from the third working state to the second working state, that is, the cold plate 10 drives the support portion 1221 to move to the direction close to the second mounting portion 400, the support portion 1221 stops moving after being in contact with the positioning portion 1224, the support 122 is in the second working state, the support portion 1221 supports the cold plate 10, and the cold plate 10 is placed on the support portion 1221.For other support pieces 122, in the third working state: the support part 1221 is at least partially located in the placement area 300, the support part 1221 is not in contact with the positioning part 1224, in the first direction, the counterweight part 1223 is in abutment with the counterweight part 1223 of the adjacent support piece 122 close to the second mounting part 400 side, because the second mounting part 400 is fixedly connected with the first end part 1231 of the shell 123, the counterweight part 1223 has a tendency to rotate towards the second mounting part 400, therefore the counterweight part 1223 is in abutment with the counterweight part 1223 of the adjacent support piece 122 close to the second mounting part 400 side, which can limit the rotation of the counterweight part 1223 towards the second mounting part 400, and further make at least part of the support part 1221 located in the placement area 300, because at least part of the support part 1221 is located in the placement area 300, the cold plate 10 moves in the first direction towards the second mounting part 400 in the placement area 300, the wall part of the cold plate 10 close to the second mounting part 400 is in abutment with the part of the support part 1221 located in the placement area 300, and drives the support part 1221 to rotate towards the second mounting part 400, so that the support piece 122 changes from the third working state to the second working state, that is, the cold plate 10 drives the support part 1221 to move towards the second mounting part 400, and the support part 1221 stops rotating after being in contact with the positioning part 1224, the support piece 122 is in the second working state, the support part 1221 supports the cold plate 10, and the cold plate 10 is placed on the support part 1221; the support piece 122 is in the third working state, the other support pieces 122 located on the side of the support piece 122 close to the second mounting part 400 are in the second working state, and the other support pieces 122 located on the side of the support piece 122 away from the second mounting part 400 are in the first working state, that is, the cold plate 10 is placed on the support piece 122 located on the side of the support piece 122 close to the second mounting part 400 in the third working state, and the support piece 122 located on the side of the support piece 122 away from the second mounting part 400 is in the first working state, that is, no cold plate 10 is placed on the support piece 122 located on the side of the support piece 122 away from the bottom plate 112 in the third working state, and the next cold plate 10 to be placed moves in the placement area 300 and is placed on the support piece 122 in the third working state.

[0034] During the process of placing the cold plate 10 into the placing area 300, the support piece 122 closest to the second mounting part 400 in the first direction changes from the third working state to the second working state, and the cold plate 10 moves in the first direction towards the second mounting part 400. Since the support piece 122 closest to the second mounting part 400 in the first direction is in the third working state, the wall part of the cold plate 10 close to the second mounting part 400 abuts against the part of the support part 1221 located in the placing area 300, and drives the support part 1221 to rotate towards the second mounting part 400, so that the support piece 122 changes from the third working state to the second working state. The cold plate 10 drives the support part 1221 to move towards the second mounting part 400, and the support part 1221 stops moving after abutting against the positioning part 1224. The support piece 122 is in the second working state, the support part 1221 supports the cold plate 10, and the cold plate 10 is placed on the support part 1221. The support piece 122 closest to the second mounting part 400 in the first direction changes from the third working state to the second working state, and the rest of the support pieces 122 change from the first working state to the third working state and then to the second working state. During the process of changing to the second working state, the counterweight part 1223 moves away from the second mounting part 400, i.e. moves close to the adjacent support part 1221. The counterweight part 1223 abuts against the counterweight part 1223 of the adjacent support piece 122 and drives the counterweight part 1223 of the adjacent support piece 122 to move away from the second mounting part 400, so that the support part 1221 of the adjacent support piece 122 moves towards the second mounting part 400, and at least part of the support part 1221 of the adjacent support piece 122 is located in the placing area 300. The support piece 122 is in the second working state, and the adjacent support piece 122 changes from the first working state to the third working state. Then, the next cold plate 10 is placed into the placing area 300, so that the adjacent support piece 122 changes from the third working state to the second working state. The process of changing from the first working state to the third working state and then to the second working state is repeated, so that the stacking work of the plurality of cold plates 10 is realized. Since the support piece 122 can change from the first working state to the third working state and then to the second working state after the cold plate 10 is placed, the stacking speed of the plurality of cold plates 10 is improved, and the production rate of the workpiece is improved.

[0035] During the process of taking out the cold plate 10 placed in the placing area 300, the support 122 closest to the second mounting part 400 in the first direction is changed from the second working state to the third working state, and the rest of the supports 122 are changed from the second working state to the third working state and then to the first working state. For the rest of the supports 122, during the process of taking out the cold plate 10, the cold plate 10 farthest from the second mounting part 400 in the first direction is taken out first, the support part 1221 supporting the cold plate 10 is rotated away from the second mounting part 400, the counterweight part 1223 moves towards the second mounting part 400, and the support 122 is changed from the second working state to the third working state;

[0036] Then, among the remaining cold plates 10, the cold plate 10 farthest from the second mounting part 400 in the first direction is taken out, the support part 1221 supporting the cold plate 10 is rotated away from the second mounting part 400, the counterweight part 1223 moves towards the second mounting part 400, and the support 122 is changed from the second working state to the third working state. At the same time, due to the movement of the counterweight part 1223 towards the second mounting part 400, the counterweight part 1223 of the adjacent support 122 on the side farthest from the second mounting part 400 in the first direction is not in contact with the counterweight part 1223 of the adjacent support 122 on the side farthest from the second mounting part 400 in the first direction, and the counterweight part 1223 of the adjacent support 122 on the side farthest from the second mounting part 400 in the first direction moves towards the second mounting part 400, and the support 122 on the side farthest from the second mounting part 400 in the first direction is changed from the third working state to the first working state.

[0037] For the support 122 closest to the second mounting part 400 in the first direction, during the process of taking out the cold plate 10, the cold plate 10 is taken out in the first direction away from the second mounting part 400, the support part 1221 supporting the cold plate 10 is rotated away from the second mounting part 400, the counterweight part 1223 moves towards the second mounting part 400, and the support 122 is changed from the second working state to the third working state.
