Description

Technical Field

[0001] This utility model relates to the field of positioning pin technology, and specifically to a wear-resistant positioning pin connecting component. Background Technology

[0002] In modern industrial manufacturing, locating pin assemblies, as key components for positioning and connecting mechanical parts, are widely used in numerous scenarios such as mechanical equipment assembly, mold manufacturing, and automotive parts installation. They ensure the relative positional accuracy between components, guaranteeing the normal operation and stability of equipment.

[0003] Existing positioning pin connection assemblies are prone to severe wear during frequent insertion and removal and friction, leading to decreased positioning accuracy, shortened service life, and consequently affecting the overall performance and reliability of the equipment. Frequent component replacement also increases maintenance costs. Furthermore, due to vibration, external impacts, and other factors, the positioning pin connection assemblies are susceptible to displacement, which not only affects positioning performance but may also cause equipment malfunctions and pose safety hazards.

[0004] Based on the above, this utility model proposes a wear-resistant positioning pin connection assembly, which can effectively solve the above problems. Utility Model Content

[0005] This utility model addresses the shortcomings of the existing technology by providing a wear-resistant positioning pin connection component.

[0006] This utility model is achieved through the following technical solution:

[0007] A wear-resistant locating pin connecting assembly includes a pin rod, a stop portion fixedly connected to the bottom of the pin rod, a fixed pin seat fixedly connected to the bottom of the stop portion, a movable pin seat connected to the bottom of the fixed pin seat, an insertion hole formed at the bottom of the fixed pin seat, and an insertion rod that engages with the insertion hole at the top of the movable pin seat; limiting mechanisms restricting the movement of the movable pin seat are respectively provided on both sides of the fixed pin seat; and a wear-resistant coating is provided on the outer surfaces of the pin rod, the fixed pin seat, and the movable pin seat.

[0008] According to the above technical solution, as a further preferred technical solution, the material of the wear-resistant coating is a ceramic wear-resistant coating.

[0009] According to the above technical solution, as a further preferred technical solution, the limiting mechanism includes a first threaded hole opened on the fixed pin seat, and the first threaded hole is threadedly connected to an anti-slip bolt.

[0010] According to the above technical solution, as a further preferred technical solution, an annular groove is formed on the bottom outer surface of the movable pin seat, and a retaining spring is installed inside the annular groove.

[0011] According to the above technical solution, as a further preferred technical solution, the top of the pin is provided with a second threaded hole for pulling out.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0013] This utility model provides a wear-resistant positioning pin connection assembly. The fixed pin seat and the movable pin seat are connected by a socket and a rod, which can adjust the installation depth according to the installation requirements. The limiting mechanism on both sides of the fixed pin seat can effectively restrict the movement of the movable pin seat, avoiding unnecessary displacement of the movable pin seat due to external forces or other factors during use, thereby ensuring the stability and positioning accuracy of the positioning pin connection assembly. At the same time, the wear-resistant coating on the outer surface of the pin rod, fixed pin seat, and movable pin seat can significantly improve the wear resistance of these components, reduce wear caused by friction during frequent use, extend the service life of the assembly, and reduce the replacement frequency and cost.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0017] A wear-resistant positioning pin connection assembly includes a pin 1, a stop 2 fixedly connected to the bottom of the pin 1, a fixed pin seat 3 fixedly connected to the bottom of the stop 2, a movable pin seat 4 connected to the bottom of the fixed pin seat 3, an insertion hole 31 provided at the bottom of the fixed pin seat 3, and an insertion rod 41 provided at the top of the movable pin seat 4 that engages with the insertion hole 31; limiting mechanisms for restricting the movement of the movable pin seat 4 are respectively provided on both sides of the fixed pin seat 3; and a wear-resistant coating 5 is provided on the outer surfaces of the pin 1, the fixed pin seat 3, and the movable pin seat 4.

[0018] The fixed pin 3 and movable pin 4 of this utility model are connected by the interlocking hole 31 and the insert rod 41, which can adjust the installation depth according to the installation requirements. The limiting mechanism on both sides of the fixed pin can effectively restrict the movement of the movable pin, and avoid unnecessary displacement of the movable pin due to external forces or other factors during use, thereby ensuring the stability and positioning accuracy of the positioning pin connection assembly. At the same time, the wear-resistant coating 5 on the outer surface of the pin rod 1, fixed pin 3 and movable pin 4 can significantly improve the wear resistance of these components, reduce wear caused by friction during frequent use, extend the service life of the components, and reduce the replacement frequency and cost.

[0019] Furthermore, in another embodiment, the material of the wear-resistant coating 5 is a ceramic wear-resistant coating.

[0020] By selecting a ceramic wear-resistant coating as the material for wear-resistant coating 5, the wear resistance of the locating pin connection assembly is improved, meeting the wear resistance requirements in practical applications and extending its service life.

[0021] Furthermore, in another embodiment, the limiting mechanism includes a first threaded hole 6 formed on the fixed pin seat 3, and the first threaded hole 6 is threadedly connected to an anti-slip bolt 7.

[0022] Through the rotating shaft limiting mechanism, under the mutual cooperation of the first threaded hole 6 and the anti-slip bolt 7, the degree of limiting of the movable pin seat 4 can be conveniently adjusted by rotating the anti-slip bolt 7. This ensures that the movable pin seat 4 has a certain degree of freedom of movement, and can also be firmly limited by tightening the anti-slip bolt 7 when needed to prevent it from moving.

[0023] Furthermore, in another embodiment, an annular groove 42 is provided on the bottom outer surface of the movable pin seat 4, and a retaining spring 8 is installed inside the annular groove 42.

[0024] By setting the annular groove 42 and the retaining ring 8, the retaining ring 8 can axially position the movable pin seat 4 during component installation, preventing it from moving in the axial direction.

[0025] Furthermore, in another embodiment, the top of the pin 1 is provided with a second threaded hole 11 for pulling out.

[0026] By providing the second threaded hole 11, when it is necessary to disassemble or replace the locating pin connection assembly, a corresponding pull tool can be screwed into the second threaded hole 11, and then the pull tool can be used to apply pulling force to easily pull the entire locating pin connection assembly out of the installation position.
