Specific Embodiment

[0020] The present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] The position-limiting tooling for automotive parts, as Figure 1 shown, includes a mounting base 1. On the top surface of the mounting base 1, a position-limiting portion and clamping portions located on both sides of the position-limiting portion are fixedly connected by means of bolt locking. By providing the position-limiting portion, stable support and limitation of the parts are achieved, ensuring that the installation process of the parts is more convenient. By providing the clamping portions, clamping forces are applied to the parts to ensure that the parts can be stably clamped. The clamping portions are provided with a pre-clamping force and a locking force for restricting the parts from sliding out of the position-limiting portion. Under the action of the pre-clamping force, stable limitation during the pre-installation process of the parts is achieved during the installation process of the parts, making the pre-installation process of the parts more stable under the action of the pre-clamping force. Under the action of the locking force, stable locking and clamping of the parts are achieved.

[0022] As Figure 1 shown, the clamping portions include rigid members 2 and elastically deformable members located on both sides of the position-limiting portion. A clamping cavity 3 for placing the parts is defined between the rigid members 2 and the elastically deformable members. The elastically deformable members deform as the parts penetrate into the clamping cavity 3. The parts in the clamping cavity 3 are horizontally arranged, and the two ends in the length direction are respectively abutted against the rigid members 2 and the elastically deformable members. The distance between the rigid members 2 and the elastically deformable members is less than the length of the parts placed in the clamping cavity 3. This setting ensures that the parts placed in the clamping cavity 3 can stably push the elastically deformable members to deform elastically. The elastically deformed elastically deformable members will generate an elastic force, which is the above-mentioned pre-clamping force. By means of the elastic force generated by the elastically deformable members that elastically deform, the parts are abutted against the rigid members 2 to achieve pre-clamping during the installation process of the parts, making the installation process of the parts more convenient.

[0023] As Figure 1 shown, a horizontally arranged locking hexagon socket head bolt 4 is threadedly connected to the rigid member 2. By means of the locking hexagon socket head bolt 4, the user can apply a tightening locking force to the parts by means of the locking hexagon socket head bolt 4 to achieve stable clamping and limitation of the parts, ensuring that the parts can be stably clamped and processed.

[0024] As Figure 1 and Figure 3 shown, the position-limiting portion includes V-shaped blocks 5 distributed in an array. The openings of the V-shaped blocks 5 are vertically upward. By means of the V-shaped blocks 5, stable positioning and preliminary limitation of shaft parts are achieved.

[0025] As Figures 1 - 4As shown, the elastic deformation member includes a sliding rigid plate 6, an elastic deformation plate 7, and a rigid support plate 8 that are fixed in sequence by bonding with an adhesive. The elastic deformation plate 7 is made of cis-butadiene rubber. By utilizing the good elastic deformation performance of the cis-butadiene rubber material, it is ensured that the elastic deformation plate 7 has good and stable elastic deformation performance, enabling the elastic deformation plate 7 to stably undergo elastic deformation and generate elastic force, and ensuring that the overall elastic deformation member has good and stable elastic deformation performance. The end face of the sliding rigid plate 6 abuts against the part and is slidably connected to the rigid support plate 8. Insertion slots 9 are provided on the top surfaces of the sliding rigid plate 6, the elastic deformation plate 7, and the rigid support plate 8. A limiting rod 10 that abuts against the sliding rigid plate 6 is detachably connected in the insertion slot 9. On the groove wall of the insertion slot 9 located at the rigid support plate 8, symmetrically arranged clamping slots 11 are provided. A clamping plate 12 that penetrates into the clamping slot 11 is fixedly connected to the limiting rod 10 by welding. The provided insertion slot 9 is used for placing the limiting rod 10. Through the combined action of the clamping plate 12 and the clamping slot 11, the stable limiting of the position where the limiting rod 10 is located is achieved, ensuring that the limiting rod 10 can stably abut against the sliding rigid plate 6 and realize the stable limiting of the sliding process of the sliding rigid plate 6, enabling the sliding rigid plate 6 to be in a fixed position when the locking hexagon socket head bolt 4 is tightened, and ensuring that the locking hexagon socket head bolt 4 can stably clamp and limit the part.

[0026] As Figures 1 - 4 shown, symmetrically arranged guide rods 13 are fixedly connected to the sliding rigid plate 6 by welding. The guide rods 13 are slidably connected to the rigid support plate 8. Guide holes for the guide rods 13 to penetrate and slide are provided on the rigid support plate 8. Through the combined action of the guide rods 13 and the guide holes, the stable guiding and limiting effects on the sliding process of the sliding rigid plate 6 are achieved, ensuring that the sliding process of the sliding rigid plate 6 is smoother and more convenient. Guide inclined surfaces 14 are provided on the top sides of the mutually approaching sides of the sliding rigid plate 6 and the rigid member 2. The provided guide inclined surfaces 14 are used to guide the part into the clamping cavity 3, making the process of the part penetrating into the clamping cavity 3 more convenient.

[0027] Working principle: The overall structure is installed on the workbench by means of the mounting base 1. The limiting rod 10 is taken out from the insertion slot 9 to ensure that the locking hexagon socket head bolt 4 is located at the end face of the rigid member 2 close to the part and is screwed out. The part is placed into the opening of the clamping cavity 3 and the V-shaped block. During this process, the part will push the sliding plate to slide and squeeze the elastic deformation plate 7 to undergo elastic deformation. Under the action of the elastic force generated by the elastically deformed elastic deformation plate 7, the sliding rigid plate 6 is pushed to abut against the part and the part is pushed to abut against the end face of the rigid member 2. The part is locked by the locking hexagon socket head bolt 4 and corresponding processing is performed on the part.

[0028] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
