Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, specifically to a laser marking device for automotive oil pipes. Background Technology

[0002] In the automotive manufacturing and repair industry, oil pipes are key components for transporting fluids such as fuel and lubricating oil. They usually need to be marked on their surface with information such as specifications, production batch, and flow direction arrows to facilitate identification, assembly, and subsequent maintenance. Laser marking technology has gradually become the mainstream process for oil pipe marking due to its advantages such as clear marking, durability, and non-contact operation.

[0003] Existing laser marking equipment for automotive oil pipes typically uses a fixed marking head in conjunction with a mechanical clamp. The clamp structure is mostly of a fixed diameter, making it difficult to quickly adapt to oil pipes of different diameters (such as 8-50mm). When changing products, the machine needs to be stopped for adjustment, which affects production efficiency. Furthermore, the marking process often only allows for single-sided marking. If double-sided marking is required, the pipe needs to be clamped again or flipped, which not only increases the complexity of operation but also easily leads to positional deviation.

[0004] Therefore, a laser marking device for automotive oil pipes is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a laser marking device for automotive oil pipes in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A laser marking device for automotive oil pipes includes a cabinet body. The cabinet body is equipped with electrical control equipment inside, and a laser adjustment mechanism is provided on the rear inner wall of the cabinet body. Two sets of laser marking device bodies are symmetrically installed on the movable part of the laser adjustment mechanism for laser marking automotive oil pipes. An automotive oil pipe clamp unit is fixedly installed on the laser adjustment mechanism and located between the two sets of laser marking device bodies for fixing the automotive oil pipes.

[0007] Furthermore, the cabinet body has an inlet and an outlet on each of its two side walls, and a guide mechanism is provided on each of the two side walls of the cabinet body at the inlet and outlet.

[0008] Furthermore, the laser adjustment mechanism includes a transversely moving mold fixedly installed on the inner wall of the rear side of the cabinet body, and a U-shaped frame fixedly installed on the movable part of the transversely moving mold. A motor is fixedly installed on the top surface of the U-shaped frame, and a first bidirectional threaded rod is fixedly connected to the output end of the motor. Two sets of movable frames are threaded on the surface of the first bidirectional threaded rod. The two sets of laser marking equipment bodies are respectively fixedly installed on the movable frames and are arranged symmetrically.

[0009] Furthermore, the automotive oil pipe clamp unit includes a plate body fixedly mounted on a U-shaped frame via a support block, and the surface of the plate body has multiple sets of through slots. A support frame is installed on the top surface of the plate body at the end of the through slots. A second bidirectional threaded rod is threaded into the support frame. A knob is fixedly installed at the top end of the second bidirectional threaded rod. Two sets of movable blocks are threaded on the surface of the second bidirectional threaded rod. A clamping wheel is rotatably mounted at the end of the movable block.

[0010] Furthermore, the movable block has grooves on both sides, and the movable block slides vertically with the second bidirectional threaded rod through the grooves on both sides. The surface of the clamping wheel has an annular groove with a V-shaped cross-section to accommodate different sizes of automotive oil pipes.

[0011] Furthermore, the guiding mechanism includes a side frame fixedly installed on the outer and inner side walls of the cabinet body and corresponding to the inlet and outlet. A rotating shaft is rotatably inserted into the side frame, and a guide roller is fixedly sleeved on the surface of the rotating shaft.

[0012] The beneficial effects of this utility model are as follows: By inserting the automotive oil pipe into the main body of the cabinet, the laser marking equipment body is adjusted to clamp and fix the automotive oil pipe. The laser adjustment mechanism adjusts the position of the two sets of laser marking equipment bodies, thereby adjusting the optical path focal length of the laser marking equipment body. The host computer of the electrical control equipment sends instructions to the PLC to control the marking position of the laser marking equipment body. The host computer sends instructions to the PLC to retrieve the specified marking file, and the laser marking equipment body performs marking on the automotive oil pipe. The two sets of laser marking equipment bodies can be controlled independently, and can perform arbitrary single-sided or double-sided marking on the automotive oil pipe. Attached Figure Description

[0018] like Figures 1 to 5 As shown, a laser marking device for automotive oil pipes includes a cabinet body 1. Electrical control equipment is installed inside the cabinet body 1, and a laser adjustment mechanism 3 is installed on the rear inner wall of the cabinet body 1. Two sets of laser marking device bodies 4 are symmetrically installed on the movable part of the laser adjustment mechanism 3 for laser marking automotive oil pipes. Figure 2 and Figure 3 As shown, specifically, the laser adjustment mechanism 3 includes a transverse moving mold 301 fixedly installed on the inner wall of the rear side of the cabinet body 1, and a U-shaped frame 302 fixedly installed on the movable part of the transverse moving mold 301. A motor 303 is fixedly installed on the top surface of the U-shaped frame 302, and a first bidirectional threaded rod 304 is fixedly connected to the output end of the motor 303. Two sets of movable frames 305 are threaded on the surface of the first bidirectional threaded rod 304. Two sets of laser marking equipment bodies 4 are respectively fixedly installed on the movable frames 305 and are arranged symmetrically.

[0019] More specifically, by moving the mold 301 laterally, the lateral positions of the two sets of laser marking equipment bodies 4 and the automotive oil pipe clamp unit 5 are adjusted. The first bidirectional threaded rod 304 is driven to rotate by the motor 303, so that the two sets of movable frames 305 move synchronously in opposite directions along the threaded rod, thereby enabling the two sets of laser marking equipment bodies 4 to be focused. The two sets of laser marking equipment bodies 4 can operate independently or synchronously.

[0020] An automotive oil pipe clamp unit 5 is fixedly installed on the laser adjustment mechanism 3 and between the two sets of laser marking equipment bodies 4 for fixing the automotive oil pipe; such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, specifically, the automotive oil pipe clamp unit 5 includes a plate 501 fixedly mounted on a U-shaped frame 302 via a support block, and the surface of the plate 501 has multiple sets of through grooves 502. A support frame 503 is installed on the top surface of the plate 501 at the end of the through grooves 502. A second bidirectional threaded rod 504 is threadedly inserted into the support frame 503. A knob 505 is fixedly installed at the top of the second bidirectional threaded rod 504. Two sets of movable blocks 506 are threadedly sleeved on the surface of the second bidirectional threaded rod 504. A clamping wheel 507 is rotatably mounted at the end of the movable block 506.

[0021] More specifically, by rotating the knob 505, the second bidirectional threaded rod 504 is driven to rotate, which causes the two movable blocks 506 on both sides to move synchronously in opposite directions along the through groove 502, thereby adjusting the distance between the two sets of clamping wheels 507 to accommodate automotive oil pipes of different diameters and achieve centered clamping.

[0022] like Figure 5 As shown, in some practical applications, grooves are provided on both sides of the movable block 506, and the movable block 506 slides vertically in the second bidirectional threaded rod 504 through the grooves on both sides. The surface of the clamping wheel 507 is provided with an annular groove with a V-shaped cross section to adapt to different sizes of automotive oil pipes.

[0023] More specifically, the V-shaped annular groove on the surface of the clamping wheel 507 can adapt to the shape of oil pipes of different diameters, provide uniform radial pressure, and avoid damage to the pipe body. The grooves on both sides of the movable block 506 are located at the edge of the second bidirectional threaded rod 504 to guide and limit the movement of the movable block 506.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the two side walls of the main body of the cabinet 1 are respectively provided with an inlet 11 and an outlet 12, and a guide mechanism 2 is provided on the two side walls of the main body of the cabinet 1 at the inlet 11 and the outlet 12.

[0025] More specifically, the inlet 11 and outlet 12 on both sides of the main body 1 of the cabinet, together with the guide mechanism 2, guide the oil pipe to smoothly enter and exit the equipment, reduce friction and deviation, and ensure that the oil pipe maintains a straight movement during transmission, which is convenient for subsequent positioning and marking.

[0026] like Figure 3 As shown, specifically, the guide mechanism 2 includes a side frame 201 fixedly installed on the outer and inner side walls of the cabinet body 1 and corresponding to the inlet 11 and outlet 12. A rotating shaft 202 is rotatably inserted into the side frame 201, and a guide roller 203 is fixedly sleeved on the surface of the rotating shaft 202.

[0027] More specifically, a rotating shaft 202 is installed via a side frame 201, so that the guide roller 203 is located at the edge of the inlet 11 and the outlet 12. Through the free rotation of the guide roller 203, the oil pipe is guided by the guide roller 203 to enter the automotive oil pipe clamp unit 5 axially.

[0028] In summary: By inserting the automotive oil pipe into the main body 1 of the cabinet, the laser marking equipment body 4 is adjusted to clamp and fix the oil pipe. The laser adjustment mechanism 3 adjusts the positions of the two sets of laser marking equipment bodies 4, thereby adjusting the optical path focus of the laser marking equipment body 4. The host computer of the electrical control equipment sends instructions to the PLC to control the marking position of the laser marking equipment body 4. The host computer sends instructions to the PLC to retrieve the specified marking file. The laser marking equipment body 4 then marks the automotive oil pipe. After marking is completed, a return instruction is sent to the host computer. The car oil pipe moves, powered by an external traction device (not shown in the figure). The traction distance and speed are fed back to the marking unit through the electronic control equipment. Marking is performed within the machine frame. The traction device can make the car oil pipe move laterally and vertically to compensate for the error in the actual movement of the car oil pipe. If the car oil pipe requires marking at very short intervals, it can be moved a certain distance. The car oil pipe is stationary during marking. Alternatively, according to the requirements of the car oil pipe, vertical marking can be achieved through two sets of laser marking equipment bodies 4.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
