Description

Technical Field

[0001] This invention relates to the field of pivot pin technology, specifically to a pivot pin tool. Background Technology

[0002] Pivot pins are a type of standardized fastener that can be used for static fixed connections or for relative movement with the connected parts. They are mainly used at the hinge joints of two parts to form a hinge connection. Pivot pins are usually locked with cotter pins, which are reliable and easy to disassemble.

[0003] In many mechanical devices, the operation of many parts requires the installation of pivot pins. Referring to patent document CN215919670U, a pivot pin tool is proposed in this patent document. Although it can facilitate the installation of pivot pins and pin holes on individual parts, if two parts are to be hinged using pivot pins, the tool in the patent document needs to be used at least twice. It is not convenient to connect the pin holes on two parts using pivot pins. If two parts are to be hinged manually using pivot pins, the pin holes may not be accurately aligned, and the installation of pivot pins cannot be achieved efficiently and conveniently.

[0004] Therefore, the present invention discloses a pivot pin tool. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a pivot pin tool to solve the problem that it is inconvenient to hinge two parts using a pivot pin.

[0006] To address the aforementioned technical problems, this invention provides a pivot pin tool, the specific implementation of which is as follows:

[0007] A pivot pin tool includes a support plane. A combined guide rod is fixedly connected to the upper surface of the support plane. Two slidable lateral translation jaws are sleeved on the outer surface of the central axis of the combined guide rod. Two first telescopic springs are sleeved on the outer surfaces of the two central axes of the combined guide rod. A longitudinal translation jaw is slidably connected inside each of the two lateral translation jaws. A second telescopic spring is fixedly connected inside each of the two lateral translation jaws. The two second telescopic springs are respectively fixedly connected to the two longitudinal translation jaws. A single-unit guide rod is fixedly connected to the upper surface of the support plane. A rotary drive frame is slidably connected to the outer surface of the central axis of the single-unit guide rod. A threaded drive push rod is threadedly connected inside the rotary drive frame.

[0008] As a further optimization of the pivot pin tool provided by the present invention, fixing bolt grooves are welded at the four corners of the support plane, and a hexagonal bolt is threaded into the interior of each fixing bolt groove.

[0009] The purpose of using the above-described further optimization of the pivot pin tool provided by the present invention, is to provide a fixing bolt groove and a hexagonal bolt so that the supporting plane and its associated structure can be more stably and firmly installed on the fixing surface, thereby avoiding the problem of low installation efficiency of the pivot pin due to the device being able to move at will.

[0010] As a further optimization of the pivot pin tool provided by the present invention, anti-slip raised pads are fixedly connected to the side of the two lateral translation jaws and the two longitudinal translation jaws that are close to each other.

[0011] As a further optimization of the pivot pin tool provided by the present invention, the anti-slip raised pad is made of rubber, and the opposing surfaces of the two anti-slip raised pads are each formed with equidistant raised strips.

[0012] By adopting the above-described further optimized method of the pivot pin tool provided by the present invention, by setting anti-slip raised pads on the lateral translation claw and the longitudinal translation claw, the parts that need to be installed with pivot pins can be stably held, avoiding the situation where the pin holes on the parts are misaligned due to slippage when the lateral translation claw and the longitudinal translation claw hold and fix the parts.

[0013] As a further optimization of the pivot pin tool provided by the present invention, each of the two lateral translation claws has a power-assisted handle fixedly connected to one of its opposite sides.

[0014] By adopting the above-described further optimization of the pivot pin tool provided by the present invention, and by setting an assist handle, the lateral translation jaws can be slid more conveniently and quickly on the combined guide rod, making it easier and faster to install parts on the lateral translation jaws.

[0015] As a further optimization of the pivot pin tool provided by the present invention, each of the two longitudinal translational jaws is fixedly connected to an assisting pull block at the end away from the lateral translational jaw.

[0016] By adopting the above-described further optimization of the pivot pin tool provided by the present invention, and by setting an assistive pulling block, it is possible to more conveniently and quickly operate the longitudinal translational jaw to slide inside the lateral translational jaw.

[0017] As a further optimization of the pivot pin tool provided by the present invention, a strip-shaped placement groove is fixedly connected to the upper surface of the support plane, and the threaded drive push rod can be placed inside the strip-shaped placement groove.

[0018] As a further optimization of the pivot pin tool provided by the present invention, the rotary drive frame can rotate about the central axis of the single-piece guide rod to adjust the angle of the threaded drive push rod.

[0019] The above-described further optimization of the pivot pin tool provided by the present invention, by setting a strip-shaped placement groove, allows for the storage of the disassembled threaded drive pin, preventing the threaded drive pin from detaching from the main body of the device when it is not in use or when it is folded, thus preventing the device from becoming unusable in the future.

[0020] As a further optimization of the pivot pin tool provided by the present invention, a rotating column is fixedly connected to the end of the threaded drive pin away from the support plane, and a rotating block is rotatably connected to the end of the threaded drive pin close to the support plane.

[0021] The above-described further optimization of the pivot pin tool provided by the present invention is to facilitate and expedite the rotation of the threaded drive push rod, and to avoid the problem of low rotation efficiency of the threaded drive push rod caused by hard friction between the threaded drive push rod and the pivot pin.

[0022] Compared with the prior art, the pivot pin tool of the present invention has the following advantages:

[0023] By setting two lateral translation jaws and two longitudinal translation jaws, the parts to be hinged can be gripped and laterally displaced, ensuring precise alignment of the pin holes of the two parts. This facilitates subsequent hinged connection using a pivot pin. Simultaneously, the first telescopic spring ensures the two lateral translation jaws tend to move closer together, preventing lateral deviation of the pin holes between parts due to insufficient displacement of the lateral translation jaws. This avoids poor hinge efficiency caused by inaccurate alignment of the pin holes. Furthermore, the rotary drive frame and threaded drive push rod allow the pivot pin to be pushed into or out of the pin hole on the part when the threaded drive push rod is rotated. This enables hinged connection to be achieved with only one operation, making it more convenient and faster. Attached Figure Description

[0035] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] Embodiment 1 of the pivot pin tool of the present invention

[0038] like Figures 1 to 4 As shown, a pivot pin tool includes a support plane 1, and a combined guide rod 2 is fixedly connected to the upper surface of the support plane 1.

[0039] Each of the four corners of the supporting plane 1 is welded with a fixing bolt groove 13, and each fixing bolt groove 13 is threaded with a hexagonal bolt 14.

[0040] The purpose of setting the fixing bolt groove 13 and hexagonal bolt 14 here is to make the support plane 1 and its auxiliary structure more stable and securely installed on the fixed surface, and to avoid the problem of low installation efficiency of the pivot pin caused by the device being moved at will.

[0041] Two slidable transverse translation claws 3 are fitted on the outer surface of the central shaft of the combined guide rod 2. In order to enable the transverse translation claws 3 to slide smoothly on the pre-combined guide rod 2, the width of the transverse translation claws 3 can be appropriately increased to increase the contact area between the transverse translation claws 3 and the combined guide rod 2, so as to achieve the purpose of the transverse translation claws 3 sliding smoothly on the combined guide rod 2.

[0042] Two first telescopic springs 4 are fitted on the outer surfaces of the two central shafts of the combined guide rod 2. The interiors of the two transverse translation claws 3 are slidably connected to longitudinal translation claws 5. The interiors of the two transverse translation claws 3 are fixedly connected to second telescopic springs 6. The two second telescopic springs 6 are respectively fixedly connected to the two longitudinal translation claws 5.

[0043] like Figure 4 As shown, a circular groove of a certain length is reserved inside the longitudinal translation claw 5 so that when the longitudinal translation claw 5 is completely retracted into the interior of the transverse translation claw 3, space is reserved for the placement of the second telescopic spring 6.

[0044] A single-unit guide rod 7 is fixedly connected to the upper surface of the supporting plane 1. A rotary drive frame 8 is slidably connected to the outer surface of the central shaft of the single-unit guide rod 7. A threaded drive push rod 9 is threadedly connected to the inside of the rotary drive frame 8.

[0045] like Figure 3As shown, when the first pin hole body 10 and the second pin hole body 11 are placed on the transverse translation chuck 3, the central axis of the rotary drive frame 8 should be aligned with the central axis of the pin holes of the first pin hole body 10 and the second pin hole body 11, and the pivot pin body 12 should be pushed out or pushed into the small hole on the first pin hole body 10 and the second pin hole body 11 by the threaded drive push rod 9. Here, the pivot pin body 12 is the pivot pin mentioned above.

[0046] The length of the support plane 1 can be appropriately increased to ensure that there is sufficient length between the rotary drive frame 8, the first pin hole body 10, and the second pin hole body 11 to accommodate the pivot pin body 12.

[0047] The first pin hole body 10 and the second pin hole body 11 mentioned above are the parts that need to be hinged.

[0048] Embodiment 2 of the pivot pin tool of the present invention

[0049] In this embodiment, anti-slip raised pads 15 are fixedly connected to the sides of the two lateral translation claws 3 and the two longitudinal translation claws 5 that are close to each other.

[0050] Specifically, the anti-slip raised pad 15 is made of rubber, and the two anti-slip raised pads 15 have equidistant raised strips on their opposite surfaces.

[0051] By setting anti-slip raised pads 15 on the horizontal translation claw 3 and the vertical translation claw 5, the parts that need to be installed with pivot pins can be stably held, and the sliding of the horizontal translation claw 3 and the vertical translation claw 5 when holding and fixing the parts can be avoided, which would cause the pin holes on the parts to be misaligned.

[0052] Embodiment 3 of the pivot pin tool of the present invention

[0053] In this embodiment, the two lateral translation claws 3 are fixedly connected to the opposite sides of each other with a power handle 16.

[0054] By setting the assist handle 16, it is easier and faster to operate the lateral translation claw 3 to slide on the combined guide rod 2, making it easier and faster to install parts on the lateral translation claw 3.

[0055] In this embodiment, the ends of the two longitudinal translation claws 5 that are away from the lateral translation claws 3 are fixedly connected to the assisting pull block 17.

[0056] By setting up the assist pull block 17, it is easier and faster to operate the longitudinal translation claw 5 to slide inside the lateral translation claw 3.

[0057] Embodiment 4 of the pivot pin tool of the present invention

[0058] In this embodiment, a strip-shaped placement groove 18 is fixedly connected to the upper surface of the support plane 1, and the threaded drive rod 9 can be placed inside the strip-shaped placement groove 18.

[0059] By setting the strip-shaped placement slot 18, the disassembled threaded drive rod 9 can be stored, preventing the threaded drive rod 9 from detaching from the main body of the device when it is not in use or when it is folded, thus preventing the device from being used again.

[0060] In this embodiment, a rotating column 19 is fixedly connected to the end of the threaded drive rod 9 away from the support plane 1, and a rotating block is rotatably connected to the end of the threaded drive rod 9 close to the support plane 1.

[0061] The rotary drive frame 8 can rotate around the central axis of the single-piece guide rod 7 to adjust the angle of the threaded drive push rod 9.

[0062] The purpose of setting the rotating column 19 is to facilitate and quickly rotate the threaded drive push rod 9, and the purpose of adding the rotating block is to avoid the problem of low rotation efficiency of the threaded drive push rod 9 due to hard friction between the threaded drive push rod 9 and the pivot pin.

[0063] The specific working process of this invention is as follows:

[0064] When it is necessary to hinge two parts together using a pivot pin, first pull the two lateral translation claws 3 away from each other, and pull the two longitudinal translation claws 5 out from inside the two lateral translation claws 3. Then, insert the first pin hole body 10 and the second pin hole body 11 into the corresponding lateral translation claws 3 and longitudinal translation claws 5 respectively. Under the action of the second telescopic spring 6, the longitudinal translation claws 5 will move closer to the lateral translation claws 3, so as to clamp the first pin hole body 10 or the second pin hole body 11.

[0065] At the same time, under the action of the first telescopic spring 4, the two lateral translation claws 3 will move closer to each other and drive the pin holes on the first pin hole body 10 and the second pin hole body 11 to align. At this time, the pivot pin body 12 is aligned with the pin holes of the first pin hole body 10 and the second pin hole body 11, and the threaded drive push rod 9 located inside the rotary drive frame 8 is rotated. When the threaded drive push rod 9 rotates, it will generate relative displacement with the rotary drive frame 8, pushing the pivot pin body 12 into the pin holes of the first pin hole body 10 and the second pin hole body 11.

[0066] Similarly, by pushing the pivot pin body 12 out of the pin hole of the first pin hole body 10 and the second pin hole body 11, the above operation can be repeated. This allows for efficient and rapid installation and removal of the pivot pin. After using the tool, as follows: Figure 2 Folding tools allows for convenient storage.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0068] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
