Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, and in particular to a clamping tooling for the lower front suspension bracket of the cab. Background Technology

[0002] The front suspension lower bracket is a core component of the automotive suspension system. It mainly connects the front wheels to the vehicle body and undertakes multiple functions such as support, shock absorption, force transmission, and stability. Core components include control arms (such as A-arms, double wishbones, and multi-links), shock absorbers, coil springs / leaf springs, steering knuckles, stabilizer bars, and axles.

[0003] In automobile production and assembly plants, existing front suspension lower brackets require a clamping fixture to be fixed in place, serving as an assembly medium for the automatic tightening equipment in the next process. During the clamping process, manual operation is also required, such as connecting the outer ball cage to the wheel bearing, connecting the stabilizer bar, connecting the steering tie rod, and installing the center axle bolts. Existing clamping fixtures cannot achieve both convenience and robust multi-functionality. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art and achieve the above-mentioned functions, this utility model provides a clamping fixture for the lower front suspension bracket of the cab.

[0005] This utility model is achieved through the following technical solution: The cab front suspension lower bracket clamping fixture includes a base plate installed on a mobile production line. Dovetail groove guide rails are installed on the left and right sides of the bottom of the base plate. A vertical support plate is fixed to the outer end of the dovetail slider extending outward from the dovetail groove guide rail. The top of the support plate is an arc groove. It also includes two positioning posts welded to the upper surface of the base plate, the top of which is a rounded groove that runs through the left and right sides; A limiting block is provided at the rear center of the base plate, and the limiting block can move back and forth. It also includes square tubes located at the two rear corners of the base plate, on which telescopic rods capable of horizontal rotation are provided, and at the end of the telescopic rods are clips.

[0006] Furthermore, a baffle is fixed at the inner end of the dovetail slider, and a reinforcing rib is fixed between the dovetail slider and the support plate.

[0007] Furthermore, the front middle part of the limiting block protrudes forward in an arc, and a sliding groove is provided at the bottom of the limiting block. The limiting block is fixedly connected to the bottom locking block through a vertical plate passing through the sliding groove.

[0008] Furthermore, a rotating block is fixed to the top of the square tube, a rotating ring is provided in the groove of the rotating block, a telescopic rod is fixed on the rotating ring and a spring is built into the telescopic rod, and the card holder is semi-circular.

[0009] Furthermore, the base plate is provided with several countersunk holes for assembling it onto the assembly line.

[0010] The beneficial effects of this utility model are: This invention is applicable to front suspension underbody systems of different lengths. It adopts retractable dovetail slides on both sides, which greatly enhances the support force. It uses a horizontally rotatable elastic support as the shock absorber support component in the front suspension underbody system, which facilitates support and assembly. The bottom limit block that can be positioned forward and backward improves the fault tolerance of this invention. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0014] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] like Figures 1 to 2As shown, this utility model includes a base plate 1 installed on a mobile production line as a base plate. Dovetail groove guide rails 3 are installed on the left and right sides of the bottom of the base plate 1. The dovetail slider 301 extending outward from the dovetail groove guide rail 3 is fixed with a vertical support plate 302 at its outer end. The top of the support plate 302 is an arc groove 304, which is used to engage the outer end of the drive half shaft. The left and right extensions can accommodate front suspension brackets of different lengths on the left and right. (Mobile production lines are a conventional technology in assembly workshops, well known to those skilled in the art, and will not be described in detail here).

[0016] It also includes two positioning posts 2 welded to the upper surface of the base plate 1. The top of the positioning post 2 is a rounded groove that runs through the left and right sides, which is used to place the drive half shaft. A limiting block 501 is provided at the rear center of the base plate 1. The limiting block 501 can move back and forth, so that the assembly engineer can easily hold the lower swing arm after it is installed. It also includes square tubes 4 located at the two rear corners of the base plate 1. The square tubes 4 are equipped with telescopic rods 403 that can rotate horizontally. They can be rotated horizontally to an angle that does not hinder installation. After the front suspension lower bracket is fixed, they can be rotated back to provide support. The end of the telescopic rod 403 is equipped with a clip 404, which serves as a support component for the shock absorber in the front suspension lower bracket.

[0017] A baffle 303 is fixed at the inner end of the dovetail slider 301, and a reinforcing rib 305 is fixed between the dovetail slider 301 and the support plate 302 to provide support. Of course, the reinforcing rib 305 will affect the extension and retraction of the dovetail slider 301 to some extent, but its extension and retraction stroke is sufficient and will not cause any obstruction.

[0018] The front middle part of the limiting block 501 protrudes forward in an arc shape to facilitate contact with the arc edge of the lower swing arm. The bottom of the limiting block 501 is provided with a sliding groove 5. The limiting block 501 is fixedly connected to the bottom locking block 503 through the vertical plate 502 passing through the sliding groove 5. The vertical plate 502 is the sliding medium for the forward and backward displacement of the limiting block 501.

[0019] The top of the square tube 4 is fixed with a rotating block 401. A rotating ring 402 is provided in the groove of the rotating block 401. The telescopic rod 403 is fixed on the rotating ring 402 and has a built-in spring, i.e., elastic support. The clip is semi-circular and is clipped onto the round steel shaft of the shock absorber to ensure that the front suspension lower bracket is in a slightly backward tilted upright state.

[0020] Of course, since the telescopic rod 403 has a cylindrical sleeve structure, the rotating ring 402 itself can also rotate.

[0021] The 401 module can be assembled from top and bottom sections, a process familiar to those in the manufacturing industry, so its manufacturing process will not be described in detail here.

[0022] The base plate 1 is provided with several countersunk holes 101 for assembling it onto the assembly line to prevent the bolts from protruding and scratching the components before they leave the factory.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
