Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically to an anti-interference intake manifold vibration friction welding fixture. Background Technology

[0002] The intake manifold is a crucial component of the engine in fuel-powered vehicles such as automobiles. It primarily consists of a resonant cavity, an intake bend, and a mounting base, mostly made of functional plastics. When welding multiple pipes, they need to be fed into a vibration friction welding fixture. This fixture is a specialized tool for welding automotive engine intake manifolds. The fixture is then mounted on a vibration friction welding machine, which uses this equipment to bring the two components into contact and rub against each other under specific pressure, amplitude, and frequency. The friction generates heat, causing the material to melt at the weld interface. Under pressure, the molten plastic flows out from the weld area, forming an overflow. After the vibration stops, the molten plastic layer solidifies, thus completing the welding of the intake manifold.

[0003] The intake manifold is an important component of a car engine. When processing the intake manifold, multiple sets of pipes need to be welded using a vibration friction welding fixture. However, when welding multiple sets of pipes using existing vibration friction welding fixtures, the internal components are not easy to move. Therefore, when parts are picked up and placed on the vibration friction welding fixture, interference occurs, which affects the welding process of the intake manifold and reduces the efficiency of welding the intake manifold using the vibration friction welding fixture. Utility Model Content

[0004] The purpose of this invention is to provide an interference-resistant intake manifold vibration friction welding fixture to solve the problem mentioned in the background art that existing intake manifold vibration friction welding fixtures are prone to interference when handling parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an interference-resistant intake manifold vibration friction welding fixture, comprising: a lower fixture and an upper fixture, wherein the upper fixture is disposed on the top of the lower fixture.

[0006] A bracket a is fixedly connected to one side of the upper end face of the lower jig by bolts. A cylinder a is installed on one side of the bracket a. A slider a is fixedly connected to one end of the cylinder a. A bracket b is fixedly connected to the other side of the lower jig. A cylinder b is fixedly connected to one side of the bracket b. A slider b is fixedly connected to one end of the cylinder b.

[0007] Specifically, cylinders a and b can drive sliders a and b to move, thereby solving the interference problem that occurs in the welding fixture.

[0008] Preferably, a support frame is fixedly connected to the middle of the upper end face of the lower fixture, and multiple sets of support and positioning components are fixedly connected to one side of the upper fixture.

[0009] Specifically, the support frame is used to support and position the component b to be welded, thereby ensuring stable welding of the intake manifold.

[0010] Preferably, a mold cavity is provided on one side of the support and positioning component, and the part to be welded a is abutted against the inside of the mold cavity.

[0011] Specifically, the positioning components and the mold cavity are used to position the part to be welded, a.

[0012] Preferably, one side of the component to be welded a abuts against the component to be welded b, and one side of the component to be welded b abuts against the support frame.

[0013] Preferably, the outer side of the slider a is slidably connected to the lower jig, and the top of the lower jig is fixedly connected to multiple sets of sliding sleeves.

[0014] Preferably, a sliding rod is slidably connected inside the sliding sleeve, and one end of the sliding rod is fixed to the upper fixture.

[0015] Specifically, the sliding rod and the sliding sleeve work together to guide and position the lower and upper jigs when they are combined, maintaining their stability during the combination.

[0016] Preferably, the lower jig has multiple sets of jig flaps fixedly connected to the side near the sliding sleeve, and handles are fixedly connected to both ends of the lower jig.

[0017] Specifically, the fixture flap is used to support and position the component b to be welded.

[0018] Preferably, the outer side of the slider b is slidably connected to the lower jig.

[0019] Compared with existing technologies, the beneficial effects of this anti-interference intake manifold vibration friction welding fixture are as follows: When welding multiple sets of pipes, the fixture places the component to be welded (b) in the lower fixture, then installs the component to be welded (a) into the upper fixture, and then merges the lower and upper fixtures. The entire fixture can then be installed onto the vibration friction welding equipment for welding. To prevent interference during component handling, cylinders a and b are activated, which respectively move sliders a and b, eliminating interference. Through equipment control, the vibration friction welding fixture is automated, improving production efficiency, product quality, and reducing employee workload. This allows for rapid installation of components into the vibration friction welding fixture for welding. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 This utility model provides a technical solution: an anti-interference intake manifold vibration friction welding fixture, comprising: a lower fixture 1 and an upper fixture 2, wherein the upper fixture 2 is disposed on the top of the lower fixture 1.

[0030] A bracket a3 is fixedly connected to one side of the upper end face of the lower jig 1 by bolts. A cylinder a4 is installed on one side of the bracket a3. A slider a5 is fixedly connected to one end of the cylinder a4. A bracket b6 is fixedly connected to the other side of the lower jig 1. A cylinder b7 is fixedly connected to one side of the bracket b6. A slider b8 is fixedly connected to one end of the cylinder b7.

[0031] A support frame 9 is fixedly connected to the middle of the upper end face of the lower jig 1, and multiple sets of support and positioning components 10 are fixedly connected to one side of the upper jig 2; a mold cavity 11 is provided on one side of the support and positioning components 10, and a welding part a12 is abutted inside the mold cavity 11; a welding part b17 is abutted on one side of the welding part a12, and a side of the welding part b17 abuts against the support frame 9; the outer side of the slider a5 is slidably connected to the lower jig 1, and multiple sets of sliding sleeves 13 are fixedly connected to the top of the lower jig 1; a sliding rod 14 is slidably connected inside the sliding sleeve 13, and one end of the sliding rod 14 is fixed to the upper jig 2; multiple sets of fixture flaps 15 are fixedly connected to the side of the lower jig 1 near the sliding sleeve 13, and handles 16 are fixedly connected to both ends of the lower jig 1; the outer side of the slider b8 is slidably connected to the lower jig 1.

[0032] In practical implementation, this anti-interference intake manifold vibration friction welding fixture, when welding multiple sets of pipes, involves placing the part to be welded, b17, on the support frame 9 and fixture flap 15 of the lower fixture 1, then installing the part to be welded, a12, into the mold cavity 11 of the upper fixture 2, and then merging the lower fixture 1 and the upper fixture 2. Multiple sets of sliding rods 14 of the upper fixture 2 slide within multiple sets of sliding sleeves 13 of the lower fixture 1, thereby positioning the lower fixture 1 and the upper fixture 2 and maintaining the stability of the upper fixture 2 during movement. The fixture flap 15 and the support frame 9 can cooperate to limit the position of the part to be welded, while the mold cavity 11 and multiple sets of support and positioning components 10 can cooperate to limit the position of the part to be welded, a12. Subsequently, the entire vibration friction welding fixture can be installed onto the vibration friction welding equipment. The equipment is started, and the parts to be welded, a12 and b17, will rub against each other. The heat generated by the friction will melt the contact points of the parts, and they will be pressed and fused together under pressure. After welding, the pressure can be released, and the lower jig 1 and the upper jig 2 can be separated to remove the welded air manifold. In order to prevent interference in the jig when picking up and putting down parts, cylinders a4 and b7 are started, which will drive sliders a5 and b8 to move respectively, thereby eliminating the interference position. Through the control of the equipment, the operation of the vibration friction welding jig is automated, which improves the work efficiency during production, improves the product quality, and reduces the workload of employees. In this way, the parts can be quickly installed into the vibration friction welding jig and welded.

[0033] In summary: When using the anti-interference intake manifold vibration friction welding fixture, first place the part to be welded b17 in the lower fixture 1, then install the part to be welded a12 into the upper fixture 2, and then merge the lower fixture 1 and the upper fixture 2. Subsequently, the entire vibration friction welding fixture can be installed onto the vibration friction welding equipment for welding.
