AI Technical Summary
In traditional welding processes, the positioning and clamping of the car body hinge seat rely on manual operation, which leads to inaccurate positioning and uneven clamping, resulting in defects such as welding deformation and incomplete welding. In addition, the gaps between the parts are large when they are assembled, making it impossible to weld them to the car body underframe assembly.
Design a fixture for positioning hinge seats in a vehicle body, including a main frame, a longitudinal beam positioning base plate and a side positioning base plate. It is connected to the hinge seat by a threaded positioning pin and combined with a replaceable positioning pad to achieve precise positioning of the hinge seat and adapt to the fixing of different specifications.
It enables rapid and precise positioning of hinge seats, avoids gaps, improves welding quality and production efficiency, adapts to the efficient fixing of hinge seats of different specifications, and ensures the correct position and posture of workpieces during processing.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to mechanical and welding process technical field, specifically a kind of clamp for car body hinge seat positioning, for the fixation and positioning of car body hinge seat in the process of spot welding. BACKGROUND
[0002] Car body underframe hinge seat is one of common car body components, and is widely used in various dump trucks;The welding of underframe hinge seat is a key link in production process, and its welding quality directly affects the overall performance and service life of product. However, in the traditional welding process, the positioning and pressing of underframe hinge seat often rely on manual operation, there are problems such as inaccurate positioning, uneven pressing, etc., leading to welding deformation, missed welding and other defects;The gap is large when various parts are matched, and it cannot be assembled and welded with car body underframe assembly. SUMMARY
[0003] The utility model aims at overcoming the deficiencies of the prior art, and provides a clamp for car body hinge seat positioning;Mainly solve the problem of backward positioning welding process in prior art.
[0004] The technical scheme provided by the utility model is as follows: a clamp for car body hinge seat positioning, comprising a body frame, wherein the body frame is provided with longitudinal beam positioning bottom plate and side positioning bottom plate;The longitudinal beam positioning bottom plate is fixedly connected with longitudinal beam positioning backing plate, and the side positioning bottom plate is fixedly connected with side positioning backing plate;A round hole is formed in the rear part of the body frame, and a threaded positioning pin passes through the round hole and is connected with the hinge seat.
[0005] Further, the longitudinal beam positioning backing plate is connected with the longitudinal beam positioning bottom plate by first screw.
[0006] Further, the side positioning backing plate is connected with the side positioning bottom plate by second screw.
[0007] The utility model has the advantages that: 1, when using, the center of clamp is aligned with the center of car body underframe assembly, after measuring the distance from the center of hinge seat to front end, the left and right and front and rear positioning of hinge seat can be realized quickly;2, positioning backing plate can be replaced with different thickness, to avoid large gap or over-tightening when clamp and underframe assembly are matched due to part error, thereby ensuring that there is no gap when car body underframe assembly and hinge seat are matched, and ensuring product welding quality;3, the versatility and adjustment function of clamp enable hinge seat of different specifications to be fixed and welded in a short time;4, the clamp ensures that workpiece maintains correct position and posture during machining or assembly process, improves production efficiency and product quality.

[0012] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.
[0013] like Figure 1 , 2 As shown in Figure 3, a fixture for positioning a hinge seat in a vehicle body includes a main frame 1, on which a longitudinal beam positioning base plate 5 and a side positioning base plate 6 are fixed; the longitudinal beam positioning pad 3 is fixedly connected to the longitudinal beam positioning base plate 5 by a first screw 7, and the side positioning pad 4 is fixedly connected to the side positioning base plate 6 by a second screw 8; a round hole is opened at the rear of the main frame 1, and a threaded positioning pin 2 passes through the round hole to connect with the hinge seat 9.
[0014] This utility model discloses a clamp for positioning hinge seats in a vehicle body. In use, the hinge seat is first connected to the clamp via a threaded positioning pin. Then, the clamp is placed on the vehicle body underframe assembly 10, with the center of the clamp aligned with the center of the vehicle body underframe assembly 10. After measuring the distance from the center of the left and right hinge seats to the front end, the left-right and front-back positioning of the hinge seats is achieved. If there is a large gap or excessive tightness in the fit between the clamp and the vehicle body underframe assembly 10, the thickness of the longitudinal beam positioning pad and the side positioning pad can be replaced to ensure a gap-free fit between the vehicle body underframe assembly 10 and the hinge seat, thus guaranteeing the welding quality of the product. The overall device is flexible to operate and features high efficiency, high quality, and low labor intensity.
[0015] It should be understood that any technical features not described in detail in this specification belong to the prior art. Although the embodiments of this utility model patent have been described above in conjunction with the accompanying drawings, this utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make more forms under the guidance of this utility model without departing from the spirit and scope of protection of this utility model and the claims, and these all fall within the protection scope of this utility model.
