Description
Technical Field
[0001] This utility model relates to the technical field of stainless steel thin-walled tube processing equipment for automotive exhaust systems, specifically a laser cutting fixture for bent stainless steel tubes. Background Technology
[0002] With the rapid development of the automotive industry, the demand for processing stainless steel tubes for automobiles is increasing, especially in tube hole processing, where the requirements for quality, efficiency, and consistency are becoming increasingly stringent. Traditional stainless steel tube hole processing mainly relies on manual operation, including manual positioning, clamping, and drilling. However, this traditional process has many problems, seriously affecting production efficiency and product quality.
[0003] First, in traditional processes, manual positioning and clamping operations typically take 2-3 minutes to complete, while manual drilling of each hole takes approximately 1 minute. For multi-hole machining, the time required is even longer, resulting in low overall processing efficiency. Second, because the accuracy of manual positioning is difficult to guarantee, significant differences in positioning between different operators lead to inconsistent hole positions on the product, affecting product consistency and assembly accuracy. Furthermore, manual drilling places high demands on the operator's physical strength; prolonged operation can easily lead to fatigue, which in turn affects the product's appearance quality and processing stability.
[0004] These problems not only directly lead to a decline in product quality but also increase labor costs and reduce the product's market competitiveness. At the same time, customers have increasingly higher demands for product quality and delivery time, which traditional processes struggle to meet, resulting in decreased customer satisfaction. Utility Model Content
[0005] The purpose of this utility model is to provide a laser cutting fixture for bending stainless steel pipes, so as to solve the problems mentioned in the background art, such as low processing efficiency, poor product quality consistency, high labor cost, and high labor intensity in the drilling operation of stainless steel pipes.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting fixture for bent stainless steel pipes, comprising an L-shaped equipment base with a rotating shaft on its upper part, a fixture centering point at the axis of the rotating shaft, a fixture being mounted on the fixture centering point, the fixture positioning and fixing the bent pipe product, and a laser cutter being mounted above the bent pipe product; the equipment base includes a horizontally arranged base plate and a base upright plate on one short side, the rotating shaft being mounted on the side of the base upright plate near the base plate; the rotating shaft includes a rotating shaft seat with a fixture centering point at its axis; The clamping and centering device includes a cylindrical centering shaft tube, into which a clamp is inserted. The clamp includes a clamping shaft rod that can be inserted into the centering shaft tube. An upper clamp is fixed to the other end of the clamping shaft rod, and a lower clamp is bolted to the upper clamp. An inclined circular hole is provided between the upper and lower clamps, and a bent tube product is inserted therein. The tube axis of the opening portion of the bent tube product is coaxial with the clamping shaft rod. The laser cutter is mounted above the bent tube product via a bracket, and a laser cutting head is provided below the laser cutter. The laser cutting head can emit laser light and perform hole cutting operations on the bent tube product.
[0007] Preferably, a plurality of reinforcing ribs are provided between the base plate and the base upright plate.
[0008] Preferably, the rotating shaft seat is cylindrical and has a bearing inside. A rotating shaft is mounted on the bearing and passes through the rotating shaft seat and the base plate, connecting to a rotary motor. The other end of the rotating shaft is connected to a coaxial rotating disk. The other side of the rotating disk has a spiral groove and is engaged with three chuck jaws on the same circumference. A disc-shaped jaw guide plate is provided at the opening of the rotating shaft seat. The jaw guide plate has radial jaw guide grooves at positions corresponding to the three chuck jaws. A fixture center can be fixedly mounted by the three chuck jaws.
[0009] Preferably, a threaded through hole is provided on the side wall of the mandrel tube, and a locking bolt is provided in the threaded through hole.
[0010] Preferably, the upper end of the lower clamp is provided with an arc-shaped groove that matches the curvature of the bent tube product.
[0011] Preferably, the mandrel tube has multiple tubes with different diameters.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model provides a fixture combined with laser cutting to realize fully automated operation of machining stainless steel pipe holes for automobiles, completely eliminating the unstable factors of human operation, ensuring the consistency of the relative position between product parts, and significantly improving product consistency and assembly accuracy.
[0015] 2. The fully automated operation of this utility model greatly reduces the labor intensity of operators and improves the working environment; at the same time, combined with the quick positioning function of the fixture, it can achieve efficient and precise hole processing. Compared with the traditional manual drilling, which takes about 1 minute to process each hole, the processing efficiency is increased by about 20 times, significantly shortening the production cycle and meeting the needs of large-scale production.
[0016] 3. Traditional processes rely on skilled operators for manual positioning and drilling, resulting in high labor costs. This invention reduces reliance on skilled operators through automated operation, thereby lowering labor costs and improving production efficiency, thus further enhancing economic benefits.
[0017] 4. This utility model ensures the consistency of the hole area position and processing accuracy of the product through precise tooling positioning and laser cutting technology, which significantly improves product quality; at the same time, the increase in processing efficiency and the reduction in cost make the product more competitive in the market and significantly improve customer satisfaction.
