Description

Technical Field

[0001] The utility model relates to the technical field of tool positioning, in particular to a positioning tool for assembling a car door lock. Background Art

[0002] In the body manufacturing, each part has to go through several assembly, positioning, and clamping repetitions, so the welding fixture requires the use of a unified positioning reference principle. Generally, the process holes with high requirements for the position accuracy of the important surface of the important parts of the body assembly that affect the geometric shape and size of the body assembly are used as the positioning reference of the fixture. The positioning reference surface generally gives priority to the plane, and try to avoid the curved surface.

[0003] In the comparative document of a rivet conveying and feeding device proposed by announcement number CN219292658U, it is specifically proposed that "it includes a workbench, a horizontal slide is provided on the workbench, a positioning tool for fixing rivets is installed on the horizontal slide, and a positioning plate 1, a positioning plate 2 and a positioning plate 3 are provided on the top of the positioning tool, and a plurality of semicircular positioning grooves are provided on the top of the positioning plate 2 and the positioning plate 3; a lifting cylinder is also provided on the workbench, a horizontal cylinder is installed on the telescopic rod of the lifting cylinder, and a clamping claw device for clamping rivets is provided on the telescopic end of the horizontal cylinder."

[0004] The inventors have found that the comparative documents require that the gasket be placed in alignment with the semicircular positioning groove, and then the rivet is passed through manually or by a robotic arm. The manual placement of the gasket is not accurate and efficient, and the gasket is circular, so it is not conducive to positioning when placed upright. For this reason, we propose a positioning tool for assembling automobile door locks. Utility Model Content

DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Embodiment 1

[0026] Reference Figure 1-6 A positioning tool for assembling a car door lock comprises a workbench 1, wherein the upper end surface of the workbench 1 is provided with a plurality of rivet seats 2, wherein the rivet seats 2 are provided with through holes 3 in the vertical direction, and symmetrical through grooves 4 are provided on both sides of the rivet seats 2, wherein a clamping assembly 5 is slidably provided in the through grooves 4, and a lifting assembly 6 is provided at the bottom of the through hole 3, wherein the lifting assembly 6 is used to drive the clamping assembly 5 to clamp the rivet.

[0027] Reference Figure 3 The clamping assembly 5 includes a support rod 51 slidably arranged on the through slot 4 , an arc block 52 arranged at the end of the support rod 51 , and a column 53 fixedly arranged at the lower end of the support rod 51 .

[0028] It is worth mentioning here that by moving the arc block 52 toward the center of the through hole 3, the center of the rivet can be controlled in the vertical direction, thereby achieving auxiliary positioning of the rivet.

[0029] Reference Figure 4 The lower end surface of the support rod 51 is provided with a T-shaped protrusion 511, and the upper end surface of the through hole 3 is provided with symmetrical T-shaped grooves 31 on both sides, and the T-shaped protrusion 511 is slidably arranged in the T-shaped grooves 31.

[0030] In this embodiment, the T-shaped protrusion 511 and the T-shaped groove 31 cooperate with each other, so that the support rod 51 can slide closely against the upper end surface of the through hole 3, and the support rod 51 can be limited.

[0031] Reference Figure 3The width of the support rod 51 is consistent with the width of the through slot 4.

[0032] Reference Figure 4 The lifting assembly 6 includes a supporting plate a61 slidably arranged in the through hole 3, a fixing plate 62 arranged on the lower end surface of the supporting plate a61, a V-shaped groove 63 arranged on the fixing plate 62, a supporting plate b64 arranged on the lower end surface of the fixing plate 62, and a return spring 65 arranged on the lower end surface of the supporting plate b64.

[0033] It is worth mentioning here that the rivet presses the reset spring 65 downward by its own gravity, thereby driving the fixing plate 62 to move downward, so that the V-shaped groove 63 drives the support rods 51 on both sides to move inward, thereby clamping and limiting the rivet.

[0034] Reference Figure 4 The width of the V-shaped groove 63 is consistent with the width of the column 53 , and the column 53 is slidably arranged in the V-shaped groove 63 .

[0035] In this embodiment, the clamping assembly 5 can clamp and release the rivet by sliding the column 53 in the V-shaped groove 63 .

[0036] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
