Description

Technical Field

[0001] This utility model relates to the field of steel component assembly technology, specifically to a detachable steel component assembly positioning pin module. Background Technology

[0002] Detachable steel component assembly positioning pins are positioning tools used in steel structure assembly. They are primarily used to align and fix pin holes during steel component splicing, ensuring precise alignment between components. Traditional positioning pins typically use a pin shaft coupled with a spring steel B-type pin to fix the pin shaft, thereby positioning two steel components. While this type of positioning pin can position two steel components, it has the following drawbacks in practical use:

[0003] After repeated disassembly and assembly, the elasticity of the spring steel B-type pin decreases, leading to unstable positioning or even detachment. This makes it impossible to fix the spring steel B-type pin to the pin shaft. Furthermore, when the distance between two steel components is less than the length of the pin shaft, it is necessary to install a limiting piece or shim on the outside of the pin shaft to fit the positioning between the two steel components. This results in scattered parts that are easy to lose and low assembly efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a detachable steel component assembly positioning pin module, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Detachable steel component assembly positioning pin module, including:

[0007] The main positioning pin includes a base pin and an extension pin fixed to one end of the base pin. A limit pin plate is fixed to the end of the base pin away from the extension pin.

[0008] The hinge frame has an installation groove on one end of the extension pin and near the base pin. The hinge frame is symmetrically fixed in the installation groove and is hinged to a limiting baffle that contacts the end of the base pin.

[0009] The limiting slide is located between the opposite sides of the two hinged frames. It is slidably installed in the mounting groove along the direction of the base section pin. Both sides of the limiting slide are hinged with connecting rod transmission arms, and the other end of each connecting rod transmission arm is hinged to the limiting baffle.

[0010] The telescopic drive mechanism is mounted on the extension pin and connected to the limit slide. The telescopic drive mechanism causes the limit slide to slide within the mounting groove, so that the limit baffle can be in two states:

[0011] First state: The limit baffles are all in contact with the end of the base section pin;

[0012] Second state: All limit baffles are hidden inside the mounting slots;

[0013] The thickness adjustment rod is threaded through the limiting baffle, and the axial direction of the thickness adjustment rod is parallel to the axial direction of the base section pin.

[0014] This utility model provides a detachable steel component assembly positioning pin module. Compared with the prior art, it has the following advantages:

[0015] 1. By switching between two states of the limiting baffle, the positioning pin module can be quickly inserted and locked. The thickness adjustment push rod thread can adapt to different steel component thicknesses. The design of the thickness adjustment push rod axis being parallel to the axis of the base pin ensures stable contact force direction and improves assembly efficiency. It replaces the existing method of using spring steel B-type pins inserted into the through hole on the pin shaft for positioning, effectively avoiding the situation where the elastic performance of the spring steel B-type pin decreases after repeated installation and disassembly, making it impossible to fix the spring steel B-type pin to the pin shaft. At the same time, this positioning pin module forms an integrated structure, effectively avoiding the loss of parts and facilitating the carrying of this positioning pin module.

[0016] 2. The threaded groove allows the thickness adjustment rod to be temporarily fixed on the adjustment handwheel, effectively preventing the thickness adjustment rod from being lost;

[0017] 3. By replacing the pin sleeve to adapt to different hole diameters, the outer diameter is increased by sleeve to eliminate gaps, and the pin sleeve fits the base section pin shaft for the entire length to ensure uniform force distribution; the limiting sleeve expands the contact area of ​​the limiting pin plate to prevent it from sinking into the pin hole on the steel component, thus preventing the positioning pin module from effectively positioning the two steel components.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Combination Figures 1-4 As shown, the detachable steel component assembly positioning pin module provided by this utility model includes:

[0026] The main positioning pin 1 includes a base pin 11 and an extension pin 12 fixed to one end of the base pin 11. A limiting pin plate 13 is fixed to the end of the base pin 11 away from the extension pin 12. The limiting pin plate 13 is integrally formed with the base pin 11. The extension pin 12 is fixed to the base pin 11 by welding.

[0027] Two hinge frames 2 are provided. An installation groove 121 is provided on the extension pin 12 and at one end near the base pin 11. The hinge frames 2 are symmetrically installed in the installation groove 121 and at one end near the base pin 11. Each of the two hinge frames 2 is hinged to a limiting baffle 21 that can contact the end of the base pin 11 on the side that is far away from each other.

[0028] The limiting slide 3 is located between the two hinged frames 2 on opposite sides. It is slidably installed in the mounting groove 121 along the direction of the base section pin 11. Both sides of the limiting slide 3 are hinged with connecting rod transmission arms 31, and the other end of the connecting rod transmission arms 31 is respectively hinged to the limiting baffle 21.

[0029] The telescopic drive mechanism 4 is mounted on the extension pin 12 and connected to the limiting slide 3. The telescopic drive mechanism 4 causes the limiting slide 3 to slide within the mounting groove 121, so that the limiting baffle 21 can be in two states:

[0030] First state: Both limit baffles 21 are in contact with the end of the base section pin 11;

[0031] Second state: Both limit baffles 21 are hidden inside the mounting slots 121;

[0032] Two thickness adjustment rods 5 are threaded through the two limiting baffles 21 respectively. The outer wall of the thickness adjustment rod 5 is threaded, and the axis of the thickness adjustment rod 5 is parallel to the axis of the base section pin 11. It should be noted that: when the limiting baffles 21 are hidden in the mounting groove 121, the thickness adjustment rods 5 need to be disassembled first.

[0033] In this embodiment, the two states of the limiting baffle 21 are switched to achieve quick insertion and locking of the positioning pin module. The thickness adjustment rod 5 can be threaded to adapt to different steel component thicknesses. The design of the axis of the thickness adjustment rod 5 being parallel to the axis of the base pin 11 ensures stable contact force direction and improves assembly efficiency. This method replaces the existing method of using spring steel B-type pins inserted into the through holes on the pin shaft for positioning. It effectively avoids the situation where the elastic performance of the spring steel B-type pin decreases after repeated installation and disassembly, making it impossible to fix the spring steel B-type pin to the pin shaft. At the same time, this positioning pin module forms an integrated structure, effectively avoiding the loss of parts and facilitating the carrying of this positioning pin module.

[0034] Combination Figures 2-3 As shown, the telescopic drive mechanism 4 includes a threaded push rod 41 rotatably mounted on the extension pin 12. The outer wall of the threaded push rod 41 is threaded. One end of the threaded push rod 41 extends into the mounting groove 121 and is threadedly connected to the limiting slide 3, while the other end extends to the outside of the extension pin 12 and is coaxially fixed to an adjusting handwheel 42. The threaded push rod 41 is threadedly connected to the limiting slide 3, converting the rotational motion of the threaded push rod 41 into the linear motion of the limiting slide 3. The operation is simple and the positioning is accurate. The exposed design of the adjusting handwheel 42 facilitates manual operation, eliminating the need to use tools to rotate the threaded push rod 41.

[0035] Furthermore, two threaded grooves 421 are provided on the side of the adjusting handwheel 42 away from the threaded push rod 41. Each thickness adjusting rod 5 can be engaged with the threaded groove 421 respectively. The threaded groove 421 allows the thickness adjusting rod 5 to be temporarily fixed on the adjusting handwheel 42, effectively preventing the thickness adjusting rod 5 from being lost.

[0036] In this embodiment, a locking knob 51 is coaxially fixed to the end of the thickness adjusting rod 5 away from the base pin 11. A preload bearing ring 52, sleeved on the outside of the thickness adjusting rod 5, is rotatably mounted on the side of the locking knob 51 near the thickness adjusting rod 5. An anti-loosening preload spring 53, sleeved on the outside of the thickness adjusting rod 5, is fixedly mounted on the preload bearing ring 52. It is worth noting that when the anti-loosening preload spring 53 is in its natural state, the end of the anti-loosening preload spring 53 away from the preload bearing ring 52 is flush with the end of the thickness adjusting rod 5 away from the preload bearing ring 52. The preload force of the anti-loosening preload spring 53 is transmitted to the thickness adjusting rod 5 through the preload bearing ring 52, increasing the thread engagement friction and effectively preventing the thickness adjusting rod 5 from rotating naturally on the limiting baffle 21; the locking knob 51 provides operational convenience.

[0037] Specifically, a pin sleeve 6 of the same length is movably sleeved on the outside of the base pin 11. The inner wall of the pin sleeve 6 fits against the outer wall of the base pin 11. The pin sleeve 6 can be replaced to adapt to different hole diameters. The outer diameter is increased by sleeve to eliminate gaps. The pin sleeve 6 fits against the base pin 11 along its entire length to ensure uniform force distribution.

[0038] Furthermore, one end of the outer wall of the pin sleeve 6 is integrally formed with a limiting sleeve 7 that is movably sleeved outside the limiting pin plate 13. When the pin sleeve 6 is sleeved outside the base section pin shaft 11, the limiting sleeve 7 is sleeved outside the limiting pin plate 13, and the cross section between the limiting sleeve 7 and the limiting pin plate 13 is in contact. The limiting sleeve 7 expands the contact area of ​​the limiting pin plate 13 to prevent it from sinking into the inner side of the pin hole on the steel component, thus preventing the positioning pin module from effectively positioning the two steel components.

[0039] Furthermore, such as Figure 4 As shown, the outer wall of the limiting pin plate 13 has a ring-shaped array of limiting grooves 131, and the inner wall of the limiting sleeve 7 has a ring-shaped array and is integrally formed with flange positioning keys 71. The flange positioning keys 71 correspond one-to-one with the limiting grooves 131. The limiting sleeve 7 is fitted on the outside of the limiting pin plate 13, and multiple flange positioning keys 71 are located in the limiting grooves 131 and fit with the cross section between the limiting pin plate 13, so as to achieve the positioning effect between the limiting sleeve 7 and the limiting pin plate 13.

[0040] Working principle and usage process of this utility model:

[0041] During use, when splicing two adjacent steel components, after aligning the pin holes on the two steel components, the operator first rotates the thickness adjustment rod 5 by locking the knob 51, causing the thickness adjustment rod 5 to move spirally on the limit baffle 21. The thickness adjustment rod 5 is then disassembled, and then engaged with the threaded groove 421. The thickness adjustment rods 5 are then installed on the adjusting handwheel 42. The threaded push rod 41 is then rotated on the extension pin 12 by adjusting the handwheel 42, causing the limit slide 3 to slide away from the base pin 11 in the mounting groove 121. The connecting rod transmission arm 31 rotates around its own hinge point on both sides of the limit slide 3. The other end of the connecting rod transmission arm 31 rotates with the limit baffle 21, thereby causing the limit baffle 21 to rotate around the hinge frame 2, so that both limit baffles 21 are hidden in the mounting groove 121. At this time, the worker makes the limiting pin plate 13 contact the side wall of one of the steel components, and the mounting groove 121 is located on the other side of the two steel components. Then, by adjusting the handwheel 42, the threaded push rod 41 rotates in the opposite direction on the extension pin shaft 12, driving the limiting slide 3 to slide in the mounting groove 121 towards the base section pin shaft 11, so that both limiting baffles 21 are in contact with the end of the base section pin shaft 11. At this time, the limiting pin plate 13 and the two limiting baffles 21 are located on the two steel components twice, so that the position of the base section pin shaft 11 is limited by the limiting pin plate 13 and the two limiting baffles 21, and the two steel components can be positioned. This replaces the existing method of using spring steel B-type pins inserted into the through holes on the pin shaft to position the pin shaft. It effectively avoids the situation where the elastic performance of the spring steel B-type pin decreases after multiple installations and disassemblies, making it impossible to fix the spring steel B-type pin to the pin shaft. At the same time, this positioning pin module forms an integrated structure, which is convenient for carrying this positioning pin module.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
