Description

Technical Field

[0001] This utility model relates to the field of positioning equipment technology, specifically, to a positioning device for chassis structural components. Background Technology

[0002] Vehicles used for special operations have structural components mounted on their chassis to facilitate vehicle assembly. These components can be installed in various locations on the chassis, but generally require pre-welding before assembly. The structural components located at the rear of the chassis are of great importance to the overall assembly reliability and operational stability of the vehicle, therefore requiring high precision in positioning.

[0003] In certain models of special-purpose vehicles, the rear of the chassis typically features two identical structural components for assembly, such as... Figure 1 As shown, the structural component can be considered a rigid body, having surfaces and through holes for assembly, represented in the attached drawing as a rectangular block with a circular hole; positioning fixtures for structural components widely used in existing production are shown in the attached drawing. Figure 2 As shown, its end has two snap-fit ​​positions for structural components. During positioning, the snap-fit ​​positions are locked with pressure plates, bolts, etc., and the structural components are pressed tightly onto the vehicle chassis by their own weight.

[0004] Therefore, due to the requirements of their intended use, these tooling fixtures are typically designed to be bulky, difficult to manufacture, and have a very limited range of adjustment. When the vehicle chassis structure undergoes significant changes, they can no longer adapt to the new chassis structure, necessitating a redesign of the tooling. This greatly increases vehicle production costs and reduces production efficiency. Therefore, it is necessary to improve these bulky tooling fixtures with limited adjustment ranges. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a chassis structural component positioning device to solve the problems of large size, high manufacturing difficulty and small adjustment range of the existing structural component positioning fixtures, thereby improving the positioning and installation efficiency of structural components.

[0006] This utility model discloses a chassis structural component positioning device, including a positioning assembly, a support assembly, and a pressing device. The positioning assembly includes a positioning part and a mounting part, with two mounting parts provided. The positioning part and the mounting part are coaxially connected. The mounting part is used to mount the structural component. The positioning part has a positioning surface, and the mounting part is provided with a locking member for pressing the structural component onto the positioning surface. The mounting part is provided with an end hole for mounting a laser positioning device. The support assembly is mounted on the chassis and forms a closed area with the chassis. The positioning assembly is located within the closed area. One end of the pressing device abuts against the support assembly, and the other end abuts against the positioning part, for pushing the positioning assembly to press the structural component onto the chassis.

[0007] Preferably, the positioning part has a pressure-bearing surface, which is used to bear the pressure of the pressure-applying device.

[0008] Preferably, the mounting part is a screw, the two mounting parts are located at both ends of the positioning part, the end hole is provided on the end face of the mounting part opposite to the positioning part, and the locking element is a nut.

[0009] Preferably, the mounting part is provided with a limiting member, and the locking member is provided on the outside of the limiting member. The locking member is used to fasten the structural member between the positioning surface and the limiting member.

[0010] Preferably, the pressure-applying device is a jack.

[0011] Preferably, two pressure-applying devices are provided.

[0012] Preferably, the support assembly includes side supports and a top support. There are two side supports, which are symmetrically placed on both sides of the top support and fixedly connected to it. The side supports are mounted on the chassis.

[0013] Preferably, the side support member has a side support hole and a top support hole, and the top support member has a mating hole. The side support member and the top support member are fixed to each other by connectors passing through the top support hole and the mating hole. The side support hole is used to fix the side support member to the chassis by the connector.

[0014] Preferably, the top support member is provided with a hanging ring for hoisting the top support member.

[0015] Preferably, the laser positioning device is a laser reflector.

[0016] The beneficial effects of this utility model are as follows:

[0017] The positioning component of this invention only requires determining the relative positions of two structural components initially. Therefore, the positioning component can be manufactured in various lengths, resulting in a compact size, strong adaptability, and a wider adjustment range. After determining the relative positions of the structural components, laser-assisted positioning of the components on the chassis is achieved, eliminating the need for moving bulky tooling. Once positioning is complete, a pressure device quickly presses the structural components firmly onto the chassis, resulting in higher positioning and installation efficiency and significantly reduced production costs. Therefore, this invention solves the problems of large size, high manufacturing difficulty, and limited adjustment range in existing structural component positioning tooling, thereby improving the positioning and installation efficiency of structural components.

[0029] Please refer to the appendix. Figure 3 This utility model discloses a chassis structural component positioning device for positioning structural components 100 on a special operation vehicle chassis 200. It includes a positioning component 1, a support component 2, and a pressure device 3. The positioning component 1 includes a positioning part 11 and a mounting part 12. Both the positioning part 11 and the mounting part 12 are elongated structures and are coaxially arranged along the same axis. There are two mounting parts 12, which are located at both ends of the positioning part 11. The two end faces of the positioning part 11 are planes that are parallel to each other and perpendicular to the axis of the positioning part 11. These end faces are positioning surfaces 112, which are used to define the position of the structural component 100. The positioning part 11 also has an upward-facing plane, which is a pressure-bearing surface 111. The pressure-bearing surface 111 is parallel to the axis of the positioning part 11 and is used to support the pressure device 3.

[0030] In this utility model, the mounting part 12 consists of two screws. One end of the mounting part 12 is fixed inside the positioning surface 112. The end face of the mounting part 12 facing away from the positioning part 11 is provided with an end hole 121 for mounting a laser positioning device. Each mounting part 12 is provided with a limiting member 13 and a locking member 14. In this utility model, the limiting member 13 is a washer, and the locking member 14 is a nut. The locking member 14 is located outside the limiting member 13. When positioning the structural member 100, the mounting part 12 passes through the through hole of the structural member 100, and the limiting member 13 is attached to the surface of the structural member 100, so that the structural member 100 is located between the positioning surface 112 of the positioning part 11 and the limiting member 13, and is clamped after being fastened by the locking member 14.

[0031] Support assembly 2 includes side support members 21 and top support members 22. Both side support members 21 and top support members 22 are plate-shaped structures. Two side support members 21 are provided and symmetrically placed on both sides of the top support member 22. The side support members 21 have several side support holes 211 near one end and several top support holes 212 near the other end. Correspondingly, the top support members 22 have several mating holes 221 near both ends. The side support members 21 and top support members 22 pass through the top support holes 212. The connecting member 23 in the mating hole 221 is fixed to each other to form a semi-closed arch structure. The connecting member 23 is preferably a bolt and nut. The side support hole 211 is used to fix the side support member 21 to the chassis 200 of the vehicle through the connecting member 23 when positioning the structural member 100, thereby forming a closed area above the position where the structural member 100 needs to be positioned. The positioning component 1 is set in this area. In addition, the upper surface of the top support member 22 is provided with a hanging ring 222 to facilitate the hoisting of the entire support component 2.

[0032] In this invention, the pressure applying device 3 is a jack. The pressure applying device 3 is set between the positioning part 11 and the top support member 22. When it is necessary to press the structural member 100 onto the chassis 200, since the support component 2 is fixed on the chassis 200, the pressure applying device 3 applies pressure to the bearing surface 111 of the positioning part 11 and the top support member 22, which can push the positioning part 11 downward in the opposite direction and drive the mounting part 12 to press the structural member 100 onto the vehicle chassis 200, thereby locking the position of the structural member 100 and facilitating the welding work of the structural member 100. Preferably, there are two pressure applying devices 3 to ensure the balance of pressure application.

[0033] Reference Figure 3-6The working principle of this utility model is as follows: When positioning the structural component 100, firstly, a positioning component 1 with the same length as the distance between the two structural components 100 is selected. Then, the two structural components 100 are respectively inserted into the mounting part 12. After the positions of the structural components 100 are fixed by the two locking pieces 14, the spacing positioning and coaxial positioning of the structural components 100 can be achieved. Then, the positioning component 1 together with the structural components 100 is placed on the chassis 200, and the end hole 121 of the mounting part 12 is installed. A laser reflector 300 is installed, and a laser emitting device 400 is set at another location on the chassis 200. The distance is measured by the laser emitted and reflected between the two to achieve laser-assisted determination of the position of the structural component 100. Based on this, the position of the structural component 100 on the chassis 200 is continuously adjusted, and the structural component 100 is finally positioned on the chassis 200. Finally, the pressure device 3 pushes the positioning part 11 back to press the structural component 100 tightly onto the chassis 200, thus completing the positioning and pressing of the structural component 100.

[0034] The beneficial effects of this utility model are:

[0035] The positioning component 1 of this utility model only needs to determine the relative positions of the two structural components 100 at the beginning. Therefore, the positioning component 1 can be made in various lengths, which makes it compact, highly adaptable and has a wider range of adjustment. After the relative positions of the structural components 100 are determined, the positioning of the structural components 100 on the chassis 200 can be achieved by laser assistance. There is no need to move the bulky tooling as a whole. After positioning, the pressure device 3 can quickly press the structural components 100 onto the chassis 200, which makes the positioning and installation of the structural components 100 more efficient and greatly reduces the production cost.

[0036] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
