Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure oil pipe marking equipment, in particular to a marking tool. Background Art

[0002] As an important part of the diesel engine fuel system, the design and assembly quality of the high-pressure fuel pipe are directly related to the reliability of the engine. The high-pressure fuel pipe needs to be inspected during the production process, and laser marking is required for qualified inspections.

[0003] For example, the Chinese utility model patent with patent number CN203680111U discloses an oil inlet pipe marking fixture, which includes a base, a cylinder, a hand-pull valve, a claw seat, claws and a working platform. The cylinder is installed on the base, the hand-pull valve is installed on the cylinder, the claw seat is installed on the piston rod of the cylinder, the claw is installed on the claw seat, and the working platform is fixed on the base. The working platform is located above the claw seat between the claws.

[0004] The existing technology has at least the following problems: first, a clamp is often used to clamp the oil pipe before marking, and then marking is performed. The whole process is relatively complicated and the marking efficiency is low; second, different clamps need to be replaced for oil pipes of different specifications, and the replacement process is troublesome. Utility Model Content

[0005] Aiming at the deficiencies of the existing technology, the utility model develops a marking tool, which can facilitate laser marking of high-pressure oil pipes and can be adjusted according to the specifications of the high-pressure oil pipes, thereby effectively improving the marking efficiency and marking effect of the high-pressure oil pipes.

[0006] The technical solution of the utility model to solve the technical problem is: a marking tool, including a base plate, a mounting groove is penetrated through the base plate, a first support plate and a support seat are detachably provided at both ends of the top of the base plate, a first pipe groove is provided on the top of the first support plate, and a positioning groove is provided on the top of the support seat.

[0007] As an optimization, two sets of mounting slots are provided, each with mounting bolts. These two sets of slots coordinate with each other to define the adjustment direction of the base plate. The mounting bolts also allow the base plate to be mounted to the workbench and easily adjusted.

[0008] As an optimization, the first support plate is slidably arranged on the bottom plate. By slidably arranging the first support plate, the position of the first support plate can be adjusted to adapt to the specifications of the high-pressure oil pipe.

[0009] As an optimization, the first support plate is L-shaped, with two sets of limiting slots on its base. Fastening bolts are installed within the limiting slots, the inner ends of which are connected to the base. A first pipe groove is located at the top of the vertical plate of the first support plate. The limiting slots and fastening bolts facilitate adjustment of the first support plate's position and facilitate assembly and disassembly of the first support plate.

[0010] As an optimization, the support base is provided with first countersunk holes, located on either side of the positioning slot, and first bolts are installed in the first countersunk holes. By providing the first countersunk holes and first bolts, the support base can be fixedly mounted on the base plate, and the first bolts are located within the first countersunk holes, preventing the high-pressure oil pipe from colliding with the first bolts.

[0011] As an optimization, a second support plate is also provided on top of the base plate. The second support plate is disposed between the first support plate and the support seat, abutting the support seat. The second support plate is provided with a second pipe groove, which corresponds to the first pipe groove. By providing the second support plate, the first pipe groove and the second pipe groove can cooperate with the first support plate to support both ends of the high-pressure oil pipe to prevent horizontal shaking. The second support plate cooperates with the support seat to position the mounting nut at the end of the high-pressure oil pipe, axially fixing the high-pressure oil pipe, and ensuring consistent marking position.

[0012] As an optimization, the second support plate is provided with second countersunk holes, which are arranged on both sides of the second pipe groove, and second bolts are installed in the second countersunk holes. By providing the second countersunk holes and second bolts, the high-pressure oil pipe can be disassembled and replaced according to the specifications and dimensions, and the adaptability range is wide.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting the mounting groove, the base plate can be installed on the workbench, and the position of the base plate on the workbench can be adjusted, thereby adjusting the marking position; by setting the first support plate and the support seat, the two ends of the high-pressure oil pipe can be supported; by setting the first pipe groove and the positioning groove, the two ends of the high-pressure oil pipe can be limited, and the positioning groove can fix the mounting nut of the high-pressure oil pipe end, reducing the circumferential rotation of the high-pressure oil pipe and improving the marking accuracy. In addition, different first support plates and support seats can be disassembled and replaced according to the specifications and dimensions of the high-pressure oil pipe, and the adaptability range is wide.
