Description

Technical Field

[0001] This utility model relates to the field of car model installation technology, specifically a tooling fixture for positioning and installing car models. Background Technology

[0002] In the automotive model manufacturing industry, the pursuit of high-quality and high-efficiency production has always been a continuous goal. Automotive models serve a variety of purposes, from vivid marketing displays to key auxiliary tools for engineering design reviews and performance simulations during automotive R&D. As automotive design trends become more complex and diverse, models also need to accurately reproduce these characteristics. This places extremely high demands on the positioning and installation of various components during model making.

[0003] When assembling a car model, the car base needs to be placed on a fixture, and then the model car frame is installed on the car base. However, existing fixtures usually use two pressure plates to fix the car base when clamping it. When installing the model car frame, manual alignment is required, which reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling fixture for positioning and installing car models, which has the advantages of quick centering and can clamp car model base frames of different sizes. It solves the problem that current tooling fixtures are not convenient for clamping car models of different sizes and require manual centering.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for positioning and installing a car model, comprising: a support mechanism, wherein the support mechanism includes a worktable, and two transverse grooves are symmetrically provided on one side of the top of the worktable, and two longitudinal grooves are symmetrically provided on the other side;

[0006] A lateral limiting mechanism, comprising two limiting frames, each of which has a follower block at its bottom end, and the two follower blocks are slidably embedded into two transverse grooves respectively.

[0007] The longitudinal drive mechanism includes two limiting plates, each with a driven block 2 at its bottom end, and the two driven blocks 2 are slidably embedded in two longitudinal grooves respectively.

[0008] Preferably, the top of the worktable is arrayed with a number of balls, each ball being positioned between two horizontal grooves and two vertical grooves.

[0009] Preferably, several rollers are rotatably mounted on the adjacent sides of the two limiting frames, and the outer edge of each roller extends out of the inner side of the limiting frame. The two driven blocks are connected to a drive rod.

[0010] Preferably, the outer edge of the drive rod is symmetrically provided with two threads, the two threads have opposite helical directions and are helically connected to two driven blocks, and a knob is provided at one end of the drive rod.

[0011] Preferably, the two driven blocks are helically connected to a driven rod, and the outer edge of the driven rod is symmetrically provided with two threads, the helical directions of the two threads being opposite.

[0012] Preferably, a second drive block is spirally connected to the bottom of the middle part of the driven rod. The second drive block is placed below the worktable and below the first drive rod, and a second knob is provided at the end of the second drive block facing the first knob.

[0013] Preferably, each of the two limiting plates is provided with a positioning block at its top, and each of the two positioning blocks is provided with a limiting surface on an adjacent side. The limiting surface is arc-shaped and the arc is convex.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a support mechanism, a lateral limiting mechanism, and a longitudinal driving mechanism, rotates knob one, which drives drive rod one to rotate. Two driven blocks one are screwed together with the opposite spiral directions of the outer edge surface of drive rod one, thereby driving the two driven blocks one to move synchronously towards each other in two transverse grooves. The limiting frame limits the side of the car model. Rotating knob two, located below knob one, drives drive block two to rotate through screw engagement with driven rod. The two driven blocks two are driven to move synchronously towards each other through the two opposite spiral directions of the outer edge surface of driven rod. Two positioning blocks limit the sides of the car model. The arc-shaped limiting surface can fix car models of different sizes. While fixing, positioning can be performed quickly, improving the assembly efficiency of the car model.

[0016] 2. This utility model, by setting up a worktable, ball bearings, a limiting frame, a roller, a knob one, and a knob two, uses the limiting frame to limit the sides of the symmetrical car model. When the positioning blocks position the two ends of the car, the ball bearings at the top of the worktable and the rollers inside the limiting frame can reduce the friction during the positioning of the car model and reduce the wear during the assembly of the car model. The knobs one and two, located on the same side, can be operated alternately with one hand during positioning, which is more convenient. Attached Figure Description
