Description

Technical Field

[0001] This utility model relates to the field of left and right front wheel arch technology, and in particular to a production equipment for welding left and right front wheel arch components. Background Technology

[0002] The core function of the left and right front wheel arch welding assembly production equipment is to process scattered metal sheets into integrated welding assemblies that meet automotive assembly standards through two core functions: "forming and processing" and "precision welding".

[0003] For example, a positioning device for welding anti-detachment automotive front wheel arches, with authorization announcement number "CN217344257U," uses a clamping mechanism to pre-assemble the front wheel arches and place them inside the clamping mechanism. A rotating mechanism then adjusts their position, clamping the front wheel arches in place. Traditional front wheel arch welding positioning equipment often uses a fixed reference structure, requiring manual placement of the front wheel arches directly under the fixed mechanism for positioning and fixation. The placement of the front wheel arches relies entirely on the operator's experience and judgment, leading to deviations in the workpiece positioning each time. This cannot guarantee the consistency of workpiece position in mass production, and consequently causes problems such as welding point offsets and dimensional deviations in welded parts. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing a production equipment for welding left and right front wheel arches, thereby avoiding the offset of welding points.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This production equipment for welding left and right front wheel arches includes a base and vertical blocks. Vertical blocks are fixedly connected to both the front and rear sides of the left end of the base. The inner wall of the vertical block is rotatably connected to a round rod through a bearing. A horizontal plate is fixedly connected to the outer wall of the round rod. A front wheel arch fixing structure is provided at the lower end of the horizontal plate. The right end of the horizontal plate is fixedly connected to the vertical plate. The end of the vertical plate is fixedly connected to a straight plate. The straight plate and the inner wall of the base are both connected by bolt threads.

[0006] This feature allows the straight plate to be fixed to the base with bolts, facilitating the securing of the front wheel arch.

[0007] To further improve the design, the front wheel arch fixing structure includes a first Velcro strap, the lower end of the cross plate is fixedly connected to the first Velcro strap, the first Velcro strap is connected to a second Velcro strap, and the lower end of the second Velcro strap is fixedly connected to a rubber pad.

[0008] This feature allows for the replacement of rubber pads of different thicknesses to accommodate various sizes of front wheel arches.

[0009] Further improvements include ensuring that the lower end of the rubber pad abuts against the left and right front wheel arches.

[0010] This feature prevents scratches on the front wheel arch.

[0011] To further improve the design, a front wheel cover positioning structure is provided at the upper end of the base.

[0012] Further improvements include a square plate for the front wheel arch positioning structure. The base and the inner wall of the square plate are both connected to the bolt thread. The upper end of the square plate is fixedly connected to a spring. The upper end of the spring is fixedly connected to a positioning pin. A tapered guide head is fixedly connected to the upper end of the positioning pin.

[0013] This setting positions the front wheel arch cover so that it is always placed in the same position.

[0014] The beneficial effects of this utility model are as follows: Through the cooperation of the front wheel cover positioning structure and the base, the operator places the left and right front wheel covers to be processed on the upper end of the base. During placement, the positioning hole of the front wheel cover is aligned with the conical guide head of the front wheel cover positioning structure. The conical design of the conical guide head plays a guiding role. Even if there is a slight deviation in the initial placement position of the front wheel cover, during the placement process, after the bottom of the front wheel cover contacts the conical guide head, it will automatically adjust its position along the conical surface until the positioning pin is precisely inserted into the positioning hole of the front wheel cover. When the positioning pin is inserted into the positioning hole, the front wheel cover exerts downward pressure on the positioning pin. The positioning pin compresses the spring downward, and the spring generates an upward reaction force. Through the positioning pin acting on the front wheel cover, the bottom of the front wheel cover is tightly fitted to the upper end of the base, ensuring that the position of the front wheel cover is consistent each time it is placed, thereby preventing the welding point from shifting.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] See attached document Figure 1-6 In this embodiment, a production equipment for welding left and right front wheel arches includes a base 1 and vertical blocks 2. Vertical blocks 2 are fixedly connected to both the front and rear sides of the left end of the base 1, providing support for the vertical blocks 2. The inner wall of the vertical blocks 2 is rotatably connected to a round rod 3 via bearings, allowing the round rod 3 to rotate within the vertical blocks 2. A horizontal plate 4 is fixedly connected to the outer wall of the round rod 3, causing the horizontal plate 4 to rotate. A front wheel arch fixing structure 5 is provided at the lower end of the horizontal plate 4. The right end of the horizontal plate 4 is fixedly connected to a vertical plate 6, and the rotation of the horizontal plate 4 causes the vertical plate 6 to rotate. The end of the vertical plate 6 is fixedly connected to a straight plate 7. The straight plate 7 and the inner wall of the base 1 are both threaded with bolts, which fix the straight plate 7 to the base 1. The lower end of a rubber pad 503 abuts against the left and right front wheel arches, preventing scratches to the front wheel arches. A front wheel arch positioning structure 8 is provided at the upper end of the base 1.

[0024] See attached document Figure 1 , Figure 2 and Figure 4 The front wheel arch fixing structure 5 includes a first Velcro 501. The lower end of the horizontal plate 4 is fixedly connected to the first Velcro 501. The first Velcro 501 is connected to the second Velcro 502. The connection of the two Velcros facilitates the replacement of the rubber pad 503. The lower end of the second Velcro 502 is fixedly connected to the rubber pad 503. By replacing the rubber pad 503 of different thicknesses, it can accommodate front wheel arches of various sizes.

[0025] After the front wheel arch is positioned, the operator holds the vertical plate 6 and rotates it downwards. The vertical plate 6 drives the horizontal plate 4 to rotate around the round rod 3. (When the horizontal plate 4 rotates to a horizontal position and the rubber pad 503 at the lower end contacts the upper end of the front wheel arch, stop rotating the vertical plate 6. At this time, rotate the bolt to fix the straight plate 7 to the base 1 through the bolt thread. The horizontal plate 4 remains in a horizontal fixed state under the action of the vertical plate 6 and the straight plate 7. The rubber pad 503 is tightly pressed against the upper end of the front wheel arch under the pressure of the horizontal plate 4. The rubber pad 503 can not only increase the friction with the front wheel arch, but also prevent the metal horizontal plate 4 from directly contacting the front wheel arch, preventing scratches on the surface of the front wheel arch and playing a protective role.)

[0026] See attached document Figure 1-3The front wheel arch positioning structure 8 includes a square plate 801. The inner walls of the base 1 and the square plate 801 are both connected to bolts. The bolts fix the square plate 801 to the base 1. The upper end of the square plate 801 is fixedly connected to a spring 802. The upper end of the spring 802 is fixedly connected to a positioning pin 803. The model of the spring 802 is selected according to actual needs and can meet the working requirements. The upper end of the positioning pin 803 is fixedly connected to a tapered guide head 804.

[0027] The operator places the left and right front wheel covers to be processed on the upper end of the base 1. During placement, the positioning hole of the front wheel cover is aligned with the conical guide head 804 of the front wheel cover positioning structure 8. The conical design of the conical guide head 804 serves as a guide. Even if there is a slight deviation in the initial placement position of the front wheel cover, during the placement process, after the bottom of the front wheel cover contacts the conical guide head 804, it will automatically adjust its position along the conical surface until the positioning pin 803 is precisely inserted into the positioning hole of the front wheel cover. When the positioning pin 803 is inserted into the positioning hole, the front wheel cover exerts downward pressure on the positioning pin 803. The positioning pin 803 compresses the spring 802 downward, and the spring 802 generates an upward reaction force. Through the positioning pin 803, the force acts on the front wheel cover, making the bottom of the front wheel cover fit tightly against the upper end of the base 1, so that the position of the front wheel cover is consistent each time it is placed.

[0028] Working principle:

[0029] When using the equipment for producing welded left and right front wheel arch components:

[0030] Based on the dimensions of the left and right front wheel covers to be processed, select a rubber pad 503 with an appropriate thickness. If replacement is required, simply separate the first Velcro 501 and the second Velcro 502, remove the old rubber pad 503, and reattach the new rubber pad 503 with the second Velcro 502 to the first Velcro 501 at the lower end of the horizontal plate 4 to complete the adaptation and adjustment of the fixing structure, ensuring that front wheel covers of different sizes can be stably pressed in the future.

[0031] The operator places the left and right front wheel covers to be processed on the upper end of the base 1. During placement, the positioning hole of the front wheel cover is aligned with the conical guide head 804 of the front wheel cover positioning structure 8. The conical design of the conical guide head 804 serves as a guide. Even if there is a slight deviation in the initial placement position of the front wheel cover, during the placement process, after the bottom of the front wheel cover contacts the conical guide head 804, it will automatically adjust its position along the conical surface until the positioning pin 803 is precisely inserted into the positioning hole of the front wheel cover. When the positioning pin 803 is inserted into the positioning hole, the front wheel cover exerts downward pressure on the positioning pin 803. The positioning pin 803 compresses the spring 802 downward, and the spring 802 generates an upward reaction force. Through the positioning pin 803, the force acts on the front wheel cover, making the bottom of the front wheel cover fit tightly against the upper end of the base 1, so that the position of the front wheel cover is consistent each time it is placed.

[0032] After the front wheel cover is positioned, the operator holds the vertical plate 6 and rotates it downwards. The vertical plate 6 drives the horizontal plate 4 to rotate around the round rod 3. When the horizontal plate 4 rotates to a horizontal position and the rubber pad 503 at the lower end contacts the upper end of the front wheel cover, the vertical plate 6 is stopped from rotating. At this time, the bolt is rotated to fix the straight plate 7 to the base 1 through the bolt thread. The horizontal plate 4 is kept in a horizontal fixed state under the action of the vertical plate 6 and the straight plate 7. The rubber pad 503 is pressed tightly against the upper end of the front wheel cover under the pressure of the horizontal plate 4. The rubber pad 503 can not only increase the friction with the front wheel cover, but also prevent the metal horizontal plate 4 from directly contacting the front wheel cover, preventing scratches on the surface of the front wheel cover and playing a protective role.

[0033] After the front wheel cover is positioned and fixed, welding can be carried out. After welding is completed, unscrew the connecting bolts between the straight plate 7 and the base 1, rotate the vertical plate 6 to drive the horizontal plate 4 to flip upward, so that the rubber pad 503 is separated from the welded part. Then, remove the welded part from the base 1. After removing the welded part, the positioning pin 803 is reset upward under the elastic force of the spring 802, returning to the initial state, waiting for the processing of the next front wheel cover. This cycle is repeated to achieve mass production.

[0034] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
