Description

Technical Field

[0001] The utility model relates to the technical field of thermal spraying, in particular to a laser positioning device for a thermal spraying gun. Background Art

[0002] Thermal spray gun is a kind of equipment specially used for thermal spray process. Its main function is to heat the material to a molten, semi-molten or softened state and spray it at high speed to form a coating on the surface of the object to be treated. This technology can be used for many purposes, such as improving the wear resistance, corrosion resistance, insulation of parts or repairing worn parts.

[0003] In traditional thermal spraying operations, a laser positioning device is often fixed above the spray gun to accurately guide the spraying area. This installation method is often achieved with the help of bolt fastening or gluing technology. However, this fixed connection configuration, although it ensures the stable positioning of the laser instrument, has its shortcomings when it comes to necessary maintenance inspections or component replacements of the laser instrument. This is mainly reflected in the cumbersome disassembly process, which makes it difficult to efficiently complete the separation of the laser instrument and the spray gun. Utility Model Content

[0004] The utility model aims to provide a laser positioning device for a thermal spraying gun, aiming to solve the problem that the laser instrument on the spray gun in the prior art is inconvenient to maintain and overhaul or replace components.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a laser positioning device for a thermal spray gun, comprising a spray gun body, a support seat being installed on the spray gun body by bolts, a lower ring buckle being fixedly arranged on the support seat, a connecting rod being hingedly arranged on one side of the lower ring buckle, an upper ring buckle being hingedly arranged above the lower ring buckle through the connecting rod, a pressing plate being hingedly arranged on the side of the upper ring buckle away from the connecting rod, a pull rod being hingedly arranged on the side of the lower ring buckle away from the connecting rod, the other end of the pull rod being hinged to the pressing plate, a laser instrument being arranged above the spray gun body, and the laser instrument being located between the upper ring buckle and the lower ring buckle.

[0006] Preferably, two of the connecting rod and the pulling rod are symmetrically arranged to increase the stability of the connection between the upper ring buckle and the lower ring buckle.

[0007] Preferably, the inner walls of the upper and lower ring buckles are both provided with anti-slip pads.

[0008] Preferably, a control button is provided at one end of the laser instrument.

[0009] Preferably, the anti-slip pad is a rubber pad.

[0010] The beneficial effects of the utility model are:

[0011] When the utility model is in use, the lower ring buckle and the upper ring buckle are hingedly connected by using a connecting rod and a pulling rod to form an adjustable clamping mechanism, which allows the laser instrument to be disassembled and assembled quickly and without damage, greatly facilitating daily maintenance and emergency replacement.

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-3 As shown, a laser positioning device for a thermal spray gun comprises a spray gun body 1, a support seat 2 is installed on the spray gun body 1 by bolts, a lower ring buckle 3 is fixedly provided on the support seat 2, a connecting rod 4 is hingedly provided on one side of the lower ring buckle 3, an upper ring buckle 5 is hingedly provided above the lower ring buckle 3 through the connecting rod 4, a pressing plate 6 is hingedly provided on the side of the upper ring buckle 5 away from the connecting rod 4, a pull rod 7 is hingedly provided on the side of the lower ring buckle 3 away from the connecting rod 4, the other end of the pull rod 7 is hinged to the pressing plate 6, a laser instrument 9 is provided above the spray gun body 1, and the laser instrument 9 is located between the upper ring buckle 5 and the lower ring buckle 3.

[0018] In this embodiment, the lower ring buckle 3 is connected to the upper ring buckle 5 by a hinged connecting rod 4, forming an adjustable clamping mechanism. The space between the upper ring buckle 5 and the lower ring buckle 3 is just used to accommodate the laser instrument 9, ensuring the precise alignment of the laser. When the laser instrument 9 needs to be adjusted or replaced, the operator only needs to press down the pressing plate 6 to move the upper ring buckle 5 upward through the lever principle, thereby loosening the clamping of the upper ring buckle 5 on the laser instrument 9, making it easier to take and place the laser instrument 9. This design simplifies the cumbersomeness of the previous fixed installation method and improves work efficiency.

[0019] like Figure 3 As shown, two of the connecting rods 4 and the pulling rods 7 are symmetrically arranged to increase the stability of the connection between the upper ring buckle 5 and the lower ring buckle 3.

[0020] In this embodiment, the connecting rod 4 and the pull rod 7 are both symmetrically doubled to enhance the stability of the connection between the upper ring buckle 5 and the lower ring buckle 3, and maintain good positioning accuracy even in long-term operation or vibration environment.

[0021] like Figure 3 As shown, the inner walls of the upper ring buckle 5 and the lower ring buckle 3 are both provided with anti-slip pads 8.

[0022] In this embodiment, anti-slip pads 8 are additionally provided on the inner walls of the upper ring buckle 5 and the lower ring buckle 3, preferably made of rubber material, which effectively increases the friction coefficient of the contact surface with the laser instrument 9, avoids the displacement of the laser instrument 9 caused by vibration, and further consolidates the stability of positioning.

[0023] like Figure 1 As shown, a control button 10 is provided at one end of the laser instrument 9 .

[0024] In this embodiment, a switch button is specially provided at one end of the laser instrument 9, so that the operator can directly control the opening and closing of the laser without touching the complex mechanical structure, which simplifies the operation process and improves the flexibility and safety of the operation.

[0025] Working principle: The lower ring buckle 3 is connected to the upper ring buckle 5 by a hinged connecting rod 4, forming an adjustable clamping mechanism. The space between the upper ring buckle 5 and the lower ring buckle 3 is just used to accommodate the laser instrument 9, ensuring the precise alignment of the laser. When the laser instrument 9 needs to be adjusted or replaced, the operator only needs to press down the pressing plate 6 to move the upper ring buckle 5 upward through the lever principle, thereby loosening the clamping of the upper ring buckle 5 on the laser instrument 9, making it easier to take and place the laser instrument 9. This design simplifies the cumbersome fixed installation method in the past and improves work efficiency.
