[0038] See Figure 1 and Figure 3 A positioning component includes a support platform 110 and a positioning structure 120.

[0039] The support platform 110 is provided with a limiting groove 112, which is used to accommodate the first component, and the second component can be placed on the first component. For example, the support platform 110 is provided with a support surface 111, and the supporting surface 111 is provided with a limiting groove 112.

[0040] The positioning structure 120 includes a first positioning member 121a and a second positioning member 121b. The first positioning member 121a and the second positioning member 121b are disposed on the support platform 110 and located on opposite sides of the limiting groove 112. The first positioning member 121a can move toward the second positioning member 121b.

[0041] The first positioning member 121a is connected to the first positioning part 122a and the second positioning part 122b. The first positioning member 121a can move toward the second positioning member 121b to drive the first positioning part 122a through the support platform 110 to reach the limiting groove 112, and can drive the second positioning part 122b to move toward the second positioning member 121b.

[0042] It is understood that the first positioning part 122a can be positioned on the side wall of the limiting groove 112 by passing through the support platform 110 and reaching the limiting groove 112, and the second positioning part 122b can be positioned on the second positioning member 121b by moving towards the second positioning member 121b.

[0043] For example, the first positioning part 122a is located inside the support platform 110 and can move toward the limiting groove 112 under the action of the first positioning member 121a, so as to position the first component on the side wall of the limiting groove 112. The second positioning part 122b can move toward the second positioning member 121b under the action of the first positioning member 121a, so as to position the second component on the second positioning member 121b.

[0044] During positioning, the first component is first placed into the limiting groove 112, and then the second component is placed on the first component. Next, the first positioning member 121a moves closer to the second positioning member 121b, so that the first positioning part 122a connected to the first positioning member 121a can move towards the limiting groove 112 to position the first component on the side wall of the limiting groove 112. The second positioning part 122b connected to the first positioning member 121a can move towards the second positioning member 121b to position the second component on the first component on the second positioning member 121b, thereby realizing the positioning and fixing of the first component and the second component.

[0045] In other words, in the positioning component 100 of this application, a limiting groove 112 is provided on the support platform 110 to accommodate the first component. The first positioning member 121a and the second positioning member 121b are respectively arranged on both sides of the limiting groove 112. The first positioning member 121a is connected to the first positioning part 122a and the second positioning part 122b. During the positioning process, the first positioning member 121a can move towards the second positioning member 121b. Then, the first positioning member 121a can drive the first positioning part 122a and the second positioning part 122b to move respectively. The first positioning part 122a positions the first component on the side wall of the limiting groove 112, and the second positioning part 122b positions the second component placed on the first component on the second positioning member 121b. Thus, the positioning of the first component and the second component can be realized at the same time. Moreover, this positioning method makes the structure of the positioning component 100 simpler and the cost lower.

[0046] For details, please refer to Figure 1 In one embodiment, the first component may include a main body and an outer edge portion surrounding the main body. When the first component is placed in the limiting groove 112, the main body can be located within the limiting groove 112, while the outer edge portion can be supported by the support surfaces 111 surrounding the limiting groove 112. The second component placed on the first component can be supported by the outer edge portion of the first component. The edge of the second component may be flush with or protrude from the edge of the outer edge portion of the first component. When the first positioning member 121a moves, the first positioning part 122a can push the main body of the first component onto the side wall of the limiting groove 112 (understandably, this side wall is a side wall opposite to the first positioning part 122a). At the same time, the second positioning part 122b can act on the second component and push the second component onto the second positioning member 121b, thus simultaneously achieving the positioning of the first component and the second component.

[0047] See Figure 3 and Figure 4A first clearance hole 113 may be provided in the support platform 110. The first clearance hole 113 communicates with the limiting groove 112, and a first positioning part 122a is provided in the first clearance hole 113. When the first positioning member 121a moves, the first positioning part 122a can move through the first clearance hole 113 into the limiting groove 112, positioning the first component in the limiting groove 112 on the side wall of the limiting groove 112.

[0048] The second positioning member 121b protrudes from the surface of the support platform 110 to facilitate the second positioning part 122b acting on the second component and pushing the second component onto the second positioning member 121b.

[0049] Furthermore, to facilitate the positioning of the first positioning part 122a within the limiting groove 112 and the simultaneous positioning of the second part on the first part by the second positioning part 122b, while avoiding interference between the first positioning part 121a and the support platform 110 and making the entire positioning assembly 100 more compact, a clearance groove 114 can be provided on the support surface 111. The clearance groove 114 communicates with the first clearance hole 113, and at least a portion of the first positioning part 121a is located within the clearance groove 114. During positioning, the first positioning part 121a can move within the clearance groove 114. Since the first positioning part 121a can be located within the clearance groove 114, the second positioning part 122b connected to the first positioning part 121a can also move closer to the limiting groove 112.

[0050] See Figure 2 The positioning structure 120 may also include a transmission member 123 and an elastic member 124. The transmission member 123 is connected to the first positioning member 121a, and the transmission member 123 is connected to the support platform 110 by the elastic member 124. The elastic member 124 enables the transmission member 123 to drive the first positioning member 121a closer to the second positioning member 121b.

[0051] Understandably, during loading, the transmission component 123 can drive the first positioning component 121a to move away from the second positioning component 121b, so that the first positioning component 121a is away from the second positioning component 121b, in order to place the first component into the limiting groove 112 and place the second component on the first component. After the first component and the second component are loaded, the transmission component 123 can drive the first positioning component 121a to move closer to the second positioning component 121b under the elastic force of the elastic component 124, so that the first positioning part 122a can elastically press the first component onto the side wall of the limiting groove 112, and the second positioning part 122b can elastically press the second component onto the second positioning component 121b.

[0052] Furthermore, in order to facilitate the installation of the elastic element 124 between the transmission component 123 and the support platform 110, the positioning structure 120 may also include a mounting component 125, which is disposed on the support platform 110, and the elastic element 124 is connected between the mounting component 125 and the transmission component 123.

[0053] Furthermore, to improve the stability of the movement of the transmission component 123, the positioning structure 120 may also include a sliding component 126, through which the transmission component 123 is slidably mounted on the support platform 110. The sliding component 126 may be a slide rail.

[0054] The positioning structure 120 may further include a positioning drive 127. The drive end of the positioning drive 127 is connected to a follower wheel 128. The transmission member 123 is provided with a guide slope 129. The positioning drive 127 can drive the follower wheel 128 to abut against the guide slope 129, so that the transmission member 123 can drive the first positioning member 121a away from the second positioning member 121b. The positioning drive 127 may be a cylinder.

[0055] It is understood that by driving the follower wheel 128 to abut against the guide slope 129, the transmission member 123 can drive the first positioning member 121a away from the second positioning member 121b. After the follower wheel 128 is driven away from the guide slope 129, the transmission member 123 can drive the first positioning member 121a closer to the second positioning member 121b under the action of the elastic member 124.

[0056] See Figure 1 and Figure 2 To facilitate the installation and setup of the positioning structure 120 while ensuring a compact structure of the positioning assembly 100, the positioning assembly 100 may further include a support base 130. A support platform 110 is disposed on the support base 130, and an installation space 131 is formed between the support base 130 and the support platform 110. A support surface 111 is provided on the surface of the support platform 110 facing away from the installation space 131. The transmission component 123, the elastic component 124, and the mounting component 125 are located within the installation space 131. A second clearance hole 115 is provided on the support platform 110, and the transmission component 123 is connected to the first positioning component 121a through the second clearance hole 115.

[0057] In one embodiment, the support platform 110 may include a first support plate 116 and a second support plate 117. The first support plate 116 is disposed on the second support plate 117. The side of the first support plate 116 facing away from the second support plate 117 is provided with a support surface 111. The first support plate 116 is provided with a first clearance hole 113. The second support plate 117 is provided with a second clearance hole 115. An installation space 131 is formed between the second support plate 117 and the support base 130.

[0058] See Figure 1 and Figure 3 In order to improve the positioning accuracy of the first component and the second component, the positioning assembly 100 may include two sets of positioning structures 120. In one set of positioning structures 120, the first positioning member 121a and the second positioning member 121b are disposed opposite to each other on both sides of the limiting groove 112 in a first direction. In the other set of positioning structures 120, the first positioning member 121a and the second positioning member 121b are disposed opposite to each other on both sides of the limiting groove 112 in a second direction. The first direction and the second direction are perpendicular to each other.

[0059] It is understandable that by positioning the first component and the second component in the first direction and the second direction using two sets of positioning structures 120, the first component and the second component can be accurately positioned in the horizontal direction.

[0060] Further, see Figure 2 In order to facilitate the first positioning member 121a, which can drive the two sets of positioning structures 120 to move away from the second positioning member 121b, and to reduce costs and make the structure of the positioning assembly 100 more compact, the driving end of the positioning drive member 127 is connected to two follower wheels 128. Each follower wheel 128 is used to abut against the guide slope 129 on the transmission member 123 in the corresponding set of positioning structures 120.

[0061] Specifically, when the positioning drive 127 is activated, its driving end simultaneously drives two follower wheels 128 to move, causing each follower wheel 128 to abut against the guide slope 129 on the transmission member 123 in a corresponding set of positioning structures 120, and driving the corresponding transmission member 123 to move. This allows the first positioning member 121a in both positioning structures 120 to move away from the second positioning member 121b, facilitating the loading of the first and second components. When the positioning drive 127 drives the follower wheels 128 away from the guide slope 129, the transmission member 123 in each set of positioning structures 120, under the action of the corresponding elastic member 124, drives the first positioning member 121a closer to the second positioning member 121b, thus achieving positioning of the first and second components.

[0062] See Figure 5 and Figure 6 This application also provides a welding fixture, including a clamping assembly 200 and a positioning assembly 100. The clamping assembly 200 includes a clamping drive structure 210 and a clamping member 220. The clamping member 220 is provided with a third clearance hole 230, which is used to avoid the welding part between the first component and the second component. The clamping drive is driven to the clamping member 220 so that the clamping member 220 can move to face the support table 110 and can be driven to approach the support table 110 to clamp the second component to the first component.

[0063] Specifically, during loading, the clamping drive structure 210 can drive the clamping member 220 away from the support platform 110 of the positioning component 100. After the first and second components are loaded, the clamping drive structure 210 can first drive the clamping member 220 to move to face the support platform 110. Then, the clamping drive structure 210 drives the clamping member 220 to move and clamp the first and second components on the support platform 110, so that the second component is pressed on the first component to ensure the accuracy of subsequent welding.

[0064] Further, in one embodiment, the clamping drive structure 210 further includes a first clamping drive member 211 and a second clamping drive member 212. The first clamping drive member 211 is drivenly connected to the clamping member 220 so that the clamping member 220 can clamp the second component to the first component in a vertical direction. The second clamping drive member 212 is disposed within the mounting space 131 and is drivenly connected to the first clamping drive member 211 so that the first clamping drive member 211 can drive the clamping member 220 to move horizontally to face the support platform 110. The first clamping drive member 211 and the second clamping drive member 212 can be cylinders.

[0065] It is understood that in the above structure, the second clamping drive 212 is set in the installation space 131 to make full use of the space and make the structure of the welding fixture more compact.

[0066] See Figure 6 The welding fixture may also include a base plate 300 and a base 400. The base 400 is slidably disposed on the base plate 300, and the clamping device is slidably disposed on the base 400. The first clamping drive 211 is disposed on the base 400, and the second clamping drive 212 is drivenly connected to the base 400.

[0067] In one embodiment, the base 400 can also be slidably disposed on the base plate 300 via a slide rail, and the clamping member 220 can also be slidably disposed on the base 400 via a slide rail.

[0068] In one embodiment, the support seat 130 in the positioning component 100 may be disposed on the substrate 300, and the support seat 130 and the base 400 may be located on both sides of the substrate 300 respectively.

[0069] In one embodiment, the positioning drive 127 may be disposed on the substrate 300. For example, the positioning drive 127 may be fixed to the side of the substrate 300 opposite to the support base 130.

[0070] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
