Description

Technical Field

[0001] This utility model relates to the field of chain link processing equipment technology, and in particular to an adjustable eccentric push rod for processing large-size chain links. Background Technology

[0002] Links are the core units in a chain structure. They are interconnected by closed or semi-closed rings of specific shapes to form a chain structure that can transmit force, motion, or bear load. They are mainly ring-shaped components made of metal (such as steel, alloy) or non-metallic (such as high-strength plastic) materials. Their ends are connected by welding, riveting, snapping, or their own structure (such as open rings) to form a chain assembly that can transmit tension, pressure, or torque. The geometry (circular, elliptical, polygonal) and connection method (closed ring, open ring) of the links determine their mechanical properties and applicable scenarios.

[0003] In the chain link processing process, the ring bending machine is an important processing equipment, and the push rod is the core tooling in the chain link processing process. The traditional eccentric push rod for large-size chain link bending processing mainly consists of a base and an eccentric push rod. The eccentric push rod is mainly offset and welded to the base, so it can meet both the installation size requirements and the chain link size requirements.

[0004] However, existing bending machines have limitations when processing large-size chain links. Because the push rod position is fixed, it is impossible to flexibly adjust the push rod position according to the processing requirements of chain links of different sizes. As a result, some large-size chain links cannot be processed using existing bending machines, which affects the diversity of chain link processing and production efficiency.

[0005] To address this problem, this invention proposes an adjustable eccentric push rod for processing large-size chain links. Utility Model Content

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable eccentric push rod for processing large-size chain links, including a base 1. The upper surface of the base 1 has multiple linearly arrayed threaded grooves 5. The inner wall of the base 1 has a cavity 9, and the threaded grooves 5 communicate with the cavity 9. A limiting groove 3 is formed through the upper surface of the base 1 and communicates with the cavity 9. A first mounting groove 2 is formed through the inner wall of the cavity 9. A second mounting groove 6 is formed on the side of the cavity 9 away from the first mounting groove 2. The inner wall of the first mounting groove 2... An adjusting assembly 7 is rotatably connected via a bearing. A push rod 4 is fixedly connected to the upper surface of the adjusting assembly 7, and a fixing assembly 8 is provided on the upper surface of the adjusting assembly 7. The adjusting assembly 7 includes an adjusting screw 701 rotatably connected to the inner wall of the first mounting groove 2 via a bearing. A threaded adjusting block 704 is threadedly connected to the outer wall of the adjusting screw 701. The end of the adjusting screw 701 away from the first mounting groove 2 is rotatably mounted on the inner wall of the second mounting groove 6 via another bearing. A rotating disk 702 is fixedly connected to the end of the adjusting screw 701 away from the second mounting groove 6.

[0019] In actual use, when it is necessary to adjust the position of the push rod 4, the operator first uses a tool to loosen and remove the fixing screw 802 of the fixing component 8, so that it is completely disengaged from the threaded groove 5 of the base 1. Then, the operator holds the handle 703 and rotates the rotating disk 702. Since the rotating disk 702 is fixedly connected to the adjusting screw 701, the rotation of the rotating disk 702 will drive the adjusting screw 701 to rotate in the first mounting groove 2 and the second mounting groove 6 through the bearing. The rotation of the adjusting screw 701 will cause the threaded adjusting block 704 connected to its outer wall to move. The threaded adjusting block 704 is fixedly connected to the mounting plate 706 through the connecting block 705, and the connecting block 705 slides along the inner wall of the limiting slide groove 3, thereby ensuring that the threaded adjusting block 704 can only move in a straight line. In this way, the mounting plate 706 and the push rod 4 fixed on the mounting plate 706 will move with the movement of the threaded adjusting block 704.

[0020] A handle 703 is fixedly connected to the end of the rotating disk 702 away from the adjusting screw 701. An anti-detachment round block is fixedly connected to the side of the handle 703 away from the rotating disk 702 for easy gripping by the operator. A connecting block 705 is fixedly connected to the upper surface of the threaded adjusting block 704. The outer wall of the connecting block 705 is slidably connected to the inner wall of the limiting slide groove 3. A mounting plate 706 is fixedly connected to the side of the connecting block 705 away from the threaded adjusting block 704. The side of the mounting plate 706 away from the connecting block 705 is connected to the push rod 4. One end is fixedly connected; the fixing component 8 includes a fixing through hole 801 that passes through the upper surface of the mounting plate 706, a fixing screw 802 passing through the inner wall of the fixing through hole 801, and the outer wall of the fixing screw 802 being threadedly connected to the inner wall of the threaded groove 5; a fixing washer 803 is fitted on the outer wall of the fixing screw 802, and a fixing nut 804 is fixedly connected to the end of the fixing screw 802 away from the fixing through hole 801, and an internal hexagonal groove 805 is opened on the side of the fixing nut 804 away from the fixing screw 802.

[0021] In actual use, when the push rod 4 is adjusted to the appropriate position, stop rotating the adjusting screw 701. At this time, align the fixing screw 802 in the fixing assembly 8 with the corresponding threaded groove 5 on the base 1. Then, use a tool (such as a hex wrench) to insert into the internal hexagonal groove 805 of the fixing nut 804, thereby rotating the fixing screw 802 to screw it into the threaded groove 5. During the screwing process of the fixing screw 802, the fixing washer 803 will play a role in buffering and increasing friction until the fixing screw 802 is tightened, completing the position adjustment and fixing of the push rod 4. At this time, the push rod 4 and the base 1 are eccentrically set, enabling the ring bending machine to process large-specification chain links that could not be processed before.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
