Description

Technical Field

[0001] This invention belongs to the technical field of automotive parts production equipment, specifically relating to a support leg positioning fixture. Background Technology

[0002] The most prominent structural feature of off-road scissor lifts compared to conventional scissor lifts is their outrigger structure. This outrigger structure allows the off-road scissor lift to operate more stably on the ground and adapt to various complex terrains. The outrigger structure typically consists of the outrigger body, two mounting seats, and two hydraulic cylinders. The two mounting seats are installed at opposite ends of the outrigger body, and the two hydraulic cylinders are mounted on the two mounting seats respectively. During use, the outrigger structure must be kept level to prevent the off-road scissor lift from swaying or tipping over. In related technologies, when assembling the two mounting seats onto the outrigger body, they are prone to being assembled onto two different planes, which can potentially affect the operational stability of the off-road scissor lift.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] Based on this, the present invention provides a leg positioning fixture, which can position the leg body 5 and the two mounting seats 4 so that the mounting seats 4 at both ends of the leg body 5 are located in the same plane, preventing the off-road scissor lift from shaking or tipping over during operation.

[0034] like Figures 1 to 3 As shown, this application embodiment provides a leg positioning fixture, including a base 1, two end positioning components 2, and a middle positioning component 3. The two end positioning components 2 are mounted on the base 1 and configured to limit the movement of two workpieces along a first direction, a second direction, and a third direction, respectively, and are spaced apart. The middle positioning component 3 is mounted on the base 1 and configured to limit the movement of the workpiece along the first direction and the third direction, and is located between the two end positioning components 2.

[0035] It should be noted that the first direction above and below refers to the bidirectional direction along its axis, specifically as follows: Figure 1 The X-axis is shown in the diagram. The second direction, above and below, refers to the bidirectional direction along its axis, specifically as shown in the diagram. Figure 1The Y-axis is shown in the diagram. The third direction above and below refers to the bidirectional direction along its axis, specifically as shown in the diagram. Figure 1 The Z-axis is shown in the figure.

[0036] It should also be noted that in this embodiment, the workpiece includes a leg body 5 and two mounting seats 4. The two mounting seats 4 are respectively mounted at both ends of the leg body 5. Each mounting seat 4 includes a base 41, a base plate 42, a first side plate 43, two second side plates 44, and a third side plate 45. The base plate 42 is mounted on the base plate 41. The first side plate 43 is mounted on the end of the base plate 42 away from the leg body 5. The two second side plates 44 are respectively mounted on both sides of the base plate 42 and are symmetrically arranged. The third side plate 45 is mounted on the two second side plates 44 and is located at the end of the second side plates 44 away from the base 41. The leg body 5 is located between the two second side plates 44 and is engaged with the third side plate 45. Since the support leg body 5 is located between the two second side plates 44 and is engaged with the third side plate 45, both the second side plate 44 and the third side plate 45 can limit the support leg body 5, preventing the support leg body 5 from moving away from the third side plate 45 in the first direction, and also preventing the support leg body 5 from moving in the third direction.

[0037] Specifically, when using this device, the outrigger body 5 is first installed between the two mounting bases 4. Then, the assembled outrigger body 5 and the two mounting bases 4 are placed together in the positioning fixture. The workpiece is positioned by the end positioning component 2 and the middle positioning component 3. After positioning is completed, the workpiece can be welded.

[0038] The outrigger positioning fixture provided in this application employs an end positioning component 2, which can position both ends of the workpiece along a first direction, a second direction, and a third direction. During the welding process, it can prevent the workpiece from moving along the first direction, the second direction, and the third direction, facilitating welding. A middle positioning component 3 is also employed, which can position the middle of the workpiece along the first direction and the third direction. Together with the end positioning component 2, they help to improve the positioning effect.

[0039] In one embodiment of this application, please refer to Figures 1 to 3 The end positioning component 2 includes a first end positioning member 21, a second end positioning member 22, and two third end positioning members 23. The first end positioning member 21, the second end positioning member 22, and the two third end positioning members 23 are all installed on the base 1 and are spaced apart. The first end positioning member 21 can limit the workpiece along a first direction, the second end positioning member 22 can limit the workpiece along a second direction, and the third end positioning member 23 can limit the workpiece along a third direction.

[0040] This configuration, using the first end positioning member 21, can limit the workpiece from the bottom of its end, preventing the workpiece end from moving towards the base 1 in the first direction, and also serving to support the workpiece end. The second end positioning member 22 can limit the side of the workpiece end in the second direction, preventing movement in that direction. The third end positioning member 23 can limit the side of the workpiece end in a third direction, preventing movement in that direction. In summary, through the first end positioning member 21, the second end positioning member 22, and the third end positioning member 23, the workpiece can only move away from the base 1 in a third direction, ensuring complete fixation and good positioning during welding.

[0041] In one embodiment of this application, please refer to the following: Figures 1 to 3 The first end positioning component 21 includes a first end mounting block 211, a first end positioning plate 212 and a plurality of first end pin holes 213. The first end mounting block 211 is mounted on the base 1, the first end positioning plate 212 is mounted on the end of the first end mounting block 211 away from the base 1 and can limit the workpiece along the first direction. The plurality of first end pin holes 213 are all opened on the first end positioning plate 212.

[0042] This configuration, employing the first end mounting block 211, facilitates the installation of the first end positioning plate 212, improving ease of use. The first end positioning plate 212 can limit the position of the workpiece end along a first direction, thus serving as a support for the workpiece end. Multiple first end pin holes 213 correspond one-to-one with multiple through holes on the workpiece base plate 42, and are connected to the workpiece base plate 42 via external pins. With the cooperation of the external pins, the first end pin holes 213 prevent the workpiece from moving relative to the first end positioning plate 212, further improving the positioning effect.

[0043] In one embodiment of this application, see reference Figures 1 to 3 The second end positioning component 22 includes a second end mounting block 221, a second end positioning plate 222 and a plurality of second end pin holes 223. The second end mounting block 221 is mounted on the base 1, the second end positioning plate 222 is mounted on the second end mounting block 221 and can limit the workpiece along the second direction, and the plurality of second end pin holes 223 are all opened on the second end positioning plate 222.

[0044] This configuration, employing the second end mounting block 221, facilitates the installation of the second end positioning plate 222, improving ease of use. The two second end positioning plates 222 can limit the workpiece end along the second direction, preventing movement of the workpiece end in that direction. Multiple second end pin holes 223 correspond one-to-one with the multiple through holes on the first side plate 43 of the workpiece, and are connected to the first side plate 43 of the workpiece via external pins. With the cooperation of the external pins, the second end pin holes 223 prevent the workpiece from moving relative to the second end positioning plate 222 and can completely fix the workpiece along a third direction, further improving the positioning effect.

[0045] In one embodiment of this application, please refer to Figures 1 to 3 The third end positioning component 23 includes a third end mounting block 231, a third end positioning plate 232, and a plurality of third end pin holes 233. The third end mounting block 231 is mounted on the base 1, the third end positioning plate 232 is mounted on the third end mounting block 231, and can limit the workpiece along a third direction. The plurality of third end pin holes 233 are all opened in the third end positioning plate 232.

[0046] This configuration, employing a third-end mounting block 231, facilitates the installation of the third-end positioning plate 232, enhancing ease of use. The use of two third-end positioning plates 232 allows for the limiting of the workpiece end along a third direction, preventing movement of the workpiece end in that direction. Multiple third-end pin holes 233 correspond one-to-one with the multiple through holes on the workpiece's second side plate 44, and are connected to the workpiece's second side plate 44 via external pins. With the cooperation of the external pins, the third-end pin holes 233 prevent the workpiece from moving relative to the third-end positioning plate 232 and limit the workpiece along a second direction, further improving the positioning effect.

[0047] In one embodiment of this application, please refer to the following: Figures 1 to 3 The second end positioning member 22 also includes a clearance hole 224, which is formed in the second end positioning plate 222.

[0048] With this configuration, using the clearance hole 224, when it is necessary to remove the external pin from the workpiece base plate 42 and the first end positioning plate 212, the external pin can be removed from between the two first end positioning plates 212 through the clearance hole 224, which facilitates disassembly and installation and helps to improve the convenience of use.

[0049] In one embodiment of this application, see reference Figures 1 to 3The central positioning component 3 includes a central mounting plate 31 and a central positioning member 32. The central mounting plate 31 is mounted on the base 1 and can limit the workpiece along a first direction. The central positioning member 32 is connected to the side of the central mounting plate 31 facing away from the base 1 and can limit the workpiece along a third direction.

[0050] This configuration, using the central mounting plate 31, allows for the limiting of the workpiece's center along the first direction, effectively supporting the center of the workpiece. Furthermore, it facilitates the installation of the central positioning component 32, improving ease of use. The central mounting component also allows for the limiting of the workpiece's center along a third direction. In summary, the cooperation of the end positioning assembly 2 further enhances the positioning effect. In addition, the central positioning component 32 limits the workpiece along a third direction from the side of the workpiece's second side plate 44 facing away from the leg body 5. The third end positioning plate 232 limits the workpiece along a third direction from the side of the workpiece's second side plate 44 towards the leg body 5. With the cooperation of the central positioning component 32, the third end positioning plate 232 improves the device's positioning effect on the workpiece in the third direction.

[0051] In one embodiment of this application, please refer to Figures 1 to 3 The central positioning component 32 includes a first central positioning plate 321 and a second central positioning plate 322. Both the first central positioning plate 321 and the second central positioning plate 322 are connected to the central mounting plate 31 and are spaced apart.

[0052] This configuration, employing the first central positioning plate 321 and the second central positioning plate 322, allows for joint positioning of the workpiece's center. The cooperation of the second end positioning plate 222 further enhances the device's positioning effect on the workpiece in the second direction.

[0053] In one embodiment of this application, please refer to the following: Figures 1 to 3 The first central positioning plate 321 has multiple first central pin holes 323. The second central positioning plate 322 has second central pin holes 324.

[0054] This configuration, employing multiple first central pin holes 323 and second central pin holes 324, allows for one-to-one correspondence with multiple through holes on the third side plate 45, and enables insertion connection between the workpiece and the third side plate 45 via external pins. With the cooperation of the external pin holes, the first central pin holes 323 and second central pin holes 324 prevent the workpiece from moving relative to the first central positioning plate 321 and the second central positioning plate 322, and also limit the workpiece along a third direction, thus improving the positioning effect.

[0055] In one embodiment of this application, see reference Figures 1 to 3Two central positioning components 32 are provided, both of which are connected to the central mounting plate 31 and are spaced apart.

[0056] With this configuration, two central positioning elements 32 are provided, which can further improve the positioning effect of the central positioning component 3 on the center of the workpiece.
