Description

Technical Field

[0001] This utility model relates to the technical field of tricycle processing equipment, and in particular to a tricycle canopy welding device with laser positioning. Background Technology

[0002] A carport, as an outdoor protective barrier, is a protective structure used to protect vehicles from damage. It serves to provide shade, rain protection, protection against falling objects, and aesthetic enhancement. Carports are divided into fixed and mobile types. Mobile carports are mainly used on movable vehicles such as cars, electric tricycles, and electric vehicles. The main materials are canvas, tarpaulin, and plastic. They are inexpensive and a widely used product.

[0003] Most tricycles are not manufactured with a canopy frame structure, so the canopy cannot be directly installed. The frame needs to be welded later to provide basic protection and load-bearing space. The common welding points are located on the upper sides of the tricycle's cargo bed. The canopy frame is usually installed before welding, and then the welding work is carried out manually with a handheld welding gun. This method is not only inefficient but also poses certain safety hazards. In addition, the goggles and protective masks worn by manual welders can affect the accuracy of welding and affect the quality of welding. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for tricycle canopies with laser positioning, which can quickly and accurately determine the welding point and perform automated welding operations, reduce manpower consumption, improve welding efficiency and operational safety, and at the same time improve welding accuracy and ensure welding quality.

[0005] To achieve the above objectives, a welding device for a tricycle canopy with laser positioning is provided, comprising: an electric guide rail, wherein pin plates are symmetrically inserted and fixed at the center of the left and right sides of the electric guide rail, and clamps are fixedly connected to the top of the opposite side of each pin plate; rotating sleeves are rotatably connected to the upper rear side of each clamp, and threaded rods are threadedly connected to the inner side of each rotating sleeve; retaining rings are fixedly connected to the front ends of each threaded rod, and clamping plates are fixedly fitted to the outer sides of each retaining ring; the clamping plates and clamps are correspondingly clamped and fixed to the upper end of the side panel of the tricycle carriage; limiting slide rods are symmetrically fixed to the upper front side of each clamp, and the front ends of each limiting slide rod penetrate the clamping plate and slide in a forward and backward direction; an electric slider is slidably fitted to the top of the electric guide rail in a left and right direction; a servo motor is fixedly fitted to the upper front side of the electric slider; an electric push rod is fixedly fitted to the top output end of the servo motor; and the electric push rod has a front... A welding torch head is fixedly connected to the side output end, and a PLC controller is fixedly connected to the top of the electric push rod. A laser positioning sensor is embedded in the lower middle part of the front side of the PLC controller. The laser positioning sensor is located above the side panel of the tricycle carriage. Manual welding is eliminated. An electric guide rail and clamp are used to hold and fit the upper part of the tricycle carriage. Then, the electric slider drives the welding torch head to complete the automated transfer operation between welding points. At the same time, a servo motor and electric push rod are set to control the angle deflection and extension of the welding torch head for more accurate welding. In addition, the laser positioning sensor and PLC controller perform laser positioning of the canopy frame during the movement of the electric slider and control the electric slider to stop. It can quickly and accurately determine the welding point and perform welding operations, reduce labor consumption, improve welding efficiency and operation safety, and improve welding accuracy to ensure welding quality.

[0006] According to the laser-guided welding device for tricycle canopies, the front end of the welding torch is equipped with several welding nozzles of different diameters. The front ends of these nozzles are aligned horizontally with the welding contact surfaces between the side panels of the vehicle body and the frame. This allows for the selection of different nozzle models for more efficient welding operations as needed.

[0007] According to the laser-positioned tricycle canopy welding device, a hexagonal bolt head is fitted and fixed to the outer side of the rotating screw sleeve. All hexagonal bolt heads are located on the rear side of the clamp and slide against it. This facilitates control of the rotating screw sleeve using a wrench.

[0008] According to the laser-guided welding device for tricycle canopies, a fireproof liner is fixedly connected to the lower front side of the servo motor, and the front side of the fireproof liner slides and fits against the side panel of the vehicle body. This isolates and protects against welding sparks.

[0009] According to the laser-positioned tricycle canopy welding device, anti-detachment rings are fixedly connected to the outer edges of the threaded rod at opposite ends to the limiting slide rod. This prevents the threaded rod from rotating excessively and detaching from the clamping plate.

[0010] According to the laser-positioned tricycle canopy welding device, an anti-slip pad is fixedly attached to the front side of the electric guide rail, and the front side of the anti-slip pad is pressed and adhered to the side panel of the vehicle body. This prevents relative wear between the two while providing anti-slip protection.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] In this invention, manual welding is eliminated. An electric guide rail, along with a clamp, holds and fits the upper part of the tricycle's carriage. An electric slider then drives the welding torch to automatically transfer welding points. A servo motor and an electric push rod are used to control the angle deflection and extension / retraction of the welding torch for more accurate spot welding. Additionally, a laser positioning sensor, working in conjunction with a PLC controller, performs laser positioning of the carriage frame during the movement of the electric slider and controls the slider to stop. This allows for quick and accurate determination of welding points and welding operations, reducing manpower consumption, improving welding efficiency and safety, and enhancing welding accuracy to ensure welding quality.
