Description

Technical Field

[0001] This utility model relates to a rapid welding technology for electric vehicle frame parts, specifically a tooling that can quickly position head tubes, headlight brackets, and steering positioning brackets to facilitate welding. Background Technology

[0002] The head tube section on the electric vehicle frame, such as Figure 1 As shown, it includes a head tube, on which headlight brackets and steering limit brackets are welded. The headlight brackets and steering limit brackets are located on both sides and both ends of the head tube, respectively.

[0003] Conventional welding methods involve manual welding of each component. For example, in welding the headlight bracket to the head tube, since the head tube is a straight tube and easy to position, the welding process involves using a fixture to position the head tube, then manually placing the headlight bracket into contact with the head tube for welding. Then, the turn signal bracket is manually positioned and welded to the head tube. This process requires manual positioning of the headlight bracket and then a second manual positioning of the turn signal bracket to complete the welding. Although the straight head tube is easy to position using fixtures, the irregularity of the headlight bracket and turn signal bracket still necessitates manual positioning, resulting in a large workload, tedious work, and low efficiency. Furthermore, manual positioning suffers from accuracy issues and requires a high level of worker skill to reduce defective products. Therefore, how to quickly position the head tube, headlight bracket, and turn signal bracket to facilitate welding fixture installation is a pressing problem. Based on this, this utility model was designed. Utility Model Content

[0026] The present invention will be further described below through embodiments, but the scope of the present invention is not limited thereto.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] This solution is used to position the headlight bracket 1, the turn signal limit bracket 2, and the head tube 3, such as... Figure 1 As shown, this is to facilitate welding the headlight bracket and the steering limit bracket to the head tube.

[0029] Specifically, such as Figure 1-8 As shown, a positioning fixture for a headlight bracket and a steering limit bracket includes a first base plate 4, which is vertically installed. The bottom of the first base plate is fixed on a first worktable (not shown in the figure). An upper positioning mechanism for positioning the upper end of the head tube is fixedly installed at the upper end of the first base plate, and a lower positioning mechanism for positioning the lower end of the head tube and a steering limit bracket positioning mechanism for positioning the steering limit bracket and the head tube are fixedly installed at the lower end. A headlight bracket positioning mechanism for positioning the headlight bracket and the head tube is installed in the middle.

[0030] The upper positioning mechanism includes a first cylinder mounted on the first base plate, and a first limiting post is fixedly mounted on the piston rod of the first cylinder.

[0031] More specifically, a first cylinder seat 5 is fixedly installed on the upper end of the first base plate, the cylinder body of the first cylinder 6 is fixedly installed on the first cylinder seat, the piston rod of the first cylinder is fixedly connected to the first connecting plate 7, and a first limiting post 8 is fixedly installed on the lower end face of the first connecting plate. The first limiting post is in the shape of a stepped shaft, specifically including a first diameter segment and a second diameter segment fixedly connected to the upper end of the first diameter segment. The diameter of the first diameter segment is larger than the diameter of the second diameter segment, and the upper end of the first diameter segment is fixedly connected to the lower end face of the first connecting plate.

[0032] The lower positioning mechanism includes a first bracket fixedly installed at the lower end of the first base plate, a second limiting post fixedly installed on the first bracket, the second limiting post having the same axis as the first limiting post and being symmetrically arranged, the upper end of the head tube being fitted onto the first limiting post, and the lower end being fitted onto the second limiting post.

[0033] More specifically, a first bracket 9 is fixedly installed at the lower end of the first base plate, a first support plate 10 is fixedly installed at the upper end of the first bracket, a second cylinder seat 11 is fixedly installed at the lower end, and a second limiting post is fixedly installed at the upper end of the first support plate. The axes of the second limiting post and the first limiting post coincide and are symmetrically arranged.

[0034] The steering limit bracket positioning mechanism includes a second cylinder seat fixed to the lower end face of a first support plate. The second cylinder seat includes a first horizontal plate 12 fixedly connected to the first bracket and a first vertical plate 13 fixed to the end of the first horizontal plate. A second horizontal plate 14 is fixed to the lower end of the first vertical plate. The cylinder body 15 of the second cylinder is hinged to the end of the second horizontal plate. The piston rod of the second cylinder is hinged to a first connecting member 16. The first connecting member has a first mounting hole 17 and a second mounting hole 18. With the upper end face of the first connecting member as a reference, the first mounting hole is located to the left of the second mounting hole and below the second mounting hole. The projections of the first mounting hole and the second mounting hole in the horizontal and vertical directions do not intersect. The piston rod of the second cylinder is connected to a first pin 20 installed in the first mounting hole through a Y-type connector 19. The Y-type connector and the first pin can be fixed or rotated relative to each other. The first pin and the second mounting hole are clearance-fitted. The upper end of the first vertical plate is hinged to the first connector via a second pin 21 installed in the second mounting hole with a clearance fit. The upper end of the first vertical plate has a groove, forming a structure similar to that of a Y-type connector. The left end of the first support plate is fixedly connected to the first bracket, and the right end of the first support plate is fixedly connected to the second support plate. A magnetic head 30 (or positioning pin) protrudes from the upper surface of the second support plate 29. When the steering limit bracket is placed on the second support plate, the positioning pin / magnetic head extends into the hole 31 on the steering limit bracket without protruding from the hole.

[0035] The headlamp bracket positioning mechanism includes a headlamp limiting seat and a headlamp bracket base. The headlamp bracket base 22 is fixedly installed on the first base plate and located directly below the axis of the first limiting column. The first limiting seat 23 is fixedly installed on one side of the headlamp bracket base, and the second limiting seat 24 is fixedly installed on the other side. The first limiting seat is higher than the headlamp bracket base, and the height of the second limiting seat is usually equivalent to the height of the headlamp bracket base, or it may be slightly lower or higher than the headlamp bracket base. The clamping block 25 is set on the upper end face of the second limiting seat. The clamping block is fixedly connected to the telescopic rod of the third cylinder 26. The front end of the clamping block is also fixedly installed with a positioning rod 27 for insertion into the hole on the headlamp bracket for positioning. The first limiting seat has a positioning hole 29 for the positioning rod to be inserted. The positioning hole and the positioning rod are aligned on the horizontal plane.

[0036] The upper surface of the headlamp bracket is sloping, matching the angle of the headlamp bracket. When the headlamp bracket is placed on the headlamp bracket base, the two holes on the headlamp bracket are on the same horizontal plane. The headlamp bracket has a built-in magnetic head with weak magnetism to assist in positioning the headlamp bracket and make it easy to align the holes on the headlamp bracket with the positioning rod.

[0037] After the headlight bracket is placed in the headlight bracket seat, the third cylinder drives the clamping block to push the headlight bracket towards the first limit seat. The clamping block and the first limit seat clamp and fix the headlight bracket. The cylinder body of the third cylinder is fixed to the first base plate.

[0038] The clamping block and the second limiting seat can be configured as follows: the clamping block is placed directly on the upper surface of the second limiting seat, and the clamping block is driven to run by the third cylinder to form a sliding fit; or the clamping block can be suspended without contacting the second limiting seat.

[0039] During operation, the headlamp bracket is first placed on the headlamp bracket positioning seat and aligned with the positioning rod. The third cylinder drives the clamping block to move towards the first limiting seat. After the positioning rod passes through the hole, it is inserted into the positioning hole and continues to move forward, pushing the headlamp bracket to contact the first limiting seat. Thus, the headlamp bracket is clamped by the clamping block and the first limiting seat. The lower end of the head tube is fitted onto the second diameter section of the second limiting post and abuts against the step formed by the diameter difference between the second and first diameter sections. The middle part contacts the headlamp bracket. The first cylinder drives the first limiting post to move downward, so that the upper end of the head tube is fitted onto the second diameter section of the first limiting post and abuts against the step of the first limiting post. The steering limiting bracket is placed on the second support plate and is attracted by the magnetic head to contact the head tube. The extension rod of the second cylinder extends, causing the first connecting piece to rotate around the second pin shaft and press the head of the first connecting piece against the steering limiting bracket.

[0040] The aforementioned tooling allows for the simultaneous positioning of the head tube, headlight bracket, and steering limit bracket, improving the efficiency of subsequent welding work.
