Description

Technical Field

[0001] This utility model relates to the field of automobile production machinery and equipment technology, specifically a double rocker clamping mechanism. Background Technology

[0002] A dual-rocker clamping mechanism is a mechanical device that uses two sets of connecting rods to swing and achieve clamping function. It typically consists of a fixed base, a main rocker, a driven rocker, and grippers. When an external force drives the main rocker to swing, the motion is transmitted through the connecting rods, causing the driven rockers on both sides to rotate synchronously inward or outward, thereby driving the grippers to complete the clamping or releasing action. Its characteristics include a compact structure, a large force amplification ratio, and the ability to ensure clamping stability. It is suitable for machining fixtures, automated production lines, and other scenarios that require rapid clamping, and is especially suitable for centering clamping or occasions that require large clamping force.

[0003] The prior art patent application number is 202021451147.X, entitled "A Double Rocker Clamping Device for Steel Wire Rope Processing." It includes a motor output end that passes through a through hole in a support plate and is fixedly connected to the center of a rotating rod. One end of the rotating rod is hinged to a long rod, and the other end is hinged to a short rod. The other ends of the long and short rods are hinged to a fixed clamp. The fixed clamp includes an upper clamping rod, an upper clamping plate, a first clamping opening, a lower clamping plate, and a lower clamping rod. The upper and lower clamping rods are respectively penetrated by pins. One end of the pin is fixedly connected to the support plate, and the other end is fixedly connected to a baffle. The upper clamping plate is fixedly connected to the lower surface of the upper clamping rod, and the lower clamping plate is fixedly connected to the upper surface of the lower clamping plate. The inner sides of the first and second clamping openings... The device features anti-slip grooves to prevent the wire rope from slipping. The first and second clamps are arc-shaped, ensuring even force distribution on the clamped wire rope and preventing excessive localized stress that could cause deformation. However, while the structure is simple, using two clamping plates with arc-shaped grooves to hold the workpiece has limited clamping effectiveness and is unsuitable for the stable clamping requirements of workpieces of different sizes. Furthermore, the existing mechanism lacks an automatic locking function after clamping, relying solely on mechanical dead points or friction self-locking. This leads to a risk of loosening when manually unloading force or subjected to vibration, affecting clamping reliability. Especially in high-precision assembly or welding processes in automobile manufacturing, such loosening can cause workpiece displacement and reduce processing quality. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-rocker clamping mechanism, including a mounting plate, a rotating plate rotatably connected to one side of the mounting plate, a positioning groove formed on one side of the mounting plate, and the positioning grooves being evenly distributed sequentially, two clamping blocks rotatably connected to one side of the mounting plate, an installation chamber fixedly connected to one side of the clamping blocks, and a drive rod rotatably connected to one side of the installation chamber. Through a locking mechanism, after the clamping mechanism is in place, the rotating rod can be locked, preventing the rotating plate from rotating and preventing it from loosening when manually unloading force or subjected to vibration, thereby effectively improving clamping reliability. The clamping mechanism allows for adjustment of the clamping range according to requirements, and the clamping protrusions and concave blocks in the clamping mechanism cooperate to form a V-shaped clamping groove, which can stably clamp irregularly shaped or cylindrical workpieces, improving the applicability of the device.

[0006] Preferably, a rotating rod is rotatably connected to one side of the mounting plate. One end of the rotating rod passes through the mounting plate and extends to the other side of the mounting plate. One end of the rotating rod is fixedly connected to the rotating plate.

[0007] Preferably, one end of the rotating rod is fixedly connected to a mounting sleeve, and an insert rod is movably connected to the inner side of the mounting sleeve. One end of the insert rod passes through the rotating rod and extends to the inner side of the positioning groove. By inserting the insert rod into the positioning groove, the rotating rod is locked, thereby locking the rotating plate.

[0008] Preferably, the other end of the insertion rod is fixedly connected to a pull rod, one end of the pull rod passes through the mounting sleeve and extends to the outside of the mounting sleeve, and a compression spring is sleeved on the outside of the pull rod. The compression spring applies pressure to the insertion rod so that the insertion rod can be stably inserted into the positioning groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This dual rocker clamping mechanism, through a locking mechanism, can lock the rotating rod after the clamping mechanism is in place, so that the rotating plate cannot rotate, preventing the rotating plate from loosening when manually unloading force or subjected to vibration, thereby effectively improving the clamping reliability.

[0014] 2.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to again Figure 1-4This utility model provides a double rocker clamping mechanism, including a mounting plate 100. A rotating plate 110 is rotatably connected to one side of the mounting plate 100. A positioning groove 120 is formed on one side of the mounting plate 100, and the positioning grooves 120 are evenly distributed in sequence. A rotating rod 130 is rotatably connected to one side of the mounting plate 100. One end of the rotating rod 130 passes through the mounting plate 100 and extends to the other side of the mounting plate 100. One end of the rotating rod 130 is fixedly connected to the rotating plate 110. A mounting sleeve 140 is fixedly connected to one end of the rotating rod 130. The inner side of the mounting sleeve 140 is movably connected to... Insert rod 141, one end of which passes through rotating rod 130 and extends to the inner side of positioning groove 120. The other end of insert rod 141 is fixedly connected to pull rod 150. One end of pull rod 150 passes through mounting sleeve 140 and extends to the outer side of mounting sleeve 140. A compression spring 151 is sleeved on the outer side of pull rod 150. A connecting rod 160 is rotatably connected to one side of rotating plate 110. One end of connecting rod 160 is rotatably connected to upper clamping block 200. A connecting plate 170 is rotatably connected to one side of rotating plate 110. One side of connecting plate 170 is rotatably connected to lower rotating plate 110.

[0022] Specifically, by pulling the pull rod 150, the pull rod 150 drives the insertion rod 141, causing the insertion rod 141 to move and compress the compression spring 151 inside the mounting sleeve 140, causing the insertion rod 141 to move out of the positioning groove 120. This releases the insertion rod 141 from locking the rotating rod 130. Then, by rotating the rotating rod 130, the rotating plate 110 is rotated, causing the clamping mechanism to clamp the workpiece. After clamping, by releasing the pull rod 150, the compression spring 151 compressed by the insertion rod 141 extends its range and pushes the insertion rod 141 to move, causing the insertion rod 141 to insert into the positioning groove 120 and lock the rotating rod 130, thereby locking the rotating plate 110 connected to the rotating rod 130.

[0023] Example 2: Please refer to again Figure 1-4 Two clamping blocks 200 are rotatably connected to one side of the mounting plate 100. An installation chamber 210 is fixedly connected to one side of the clamping block 200. A drive rod 220 is rotatably connected to one side of the installation chamber 210. One end of the drive rod 220 passes through the installation chamber 210 and extends into the inner cavity of the installation chamber 210. A bidirectional screw 221 is fixedly connected to one end of the drive rod 220. A clamping recess 230 is screwed to the outside of the bidirectional screw 221. A clamping protrusion 240 is screwed to the outside of the bidirectional screw 221. An anti-slip groove 241 is provided on one side of the clamping protrusion 240, and the anti-slip grooves 241 are arranged in sequence.

[0024] Specifically, according to the clamping requirements, the bidirectional screw 221 connected to the drive rod 220 is rotated by rotating the drive rod 220, so that the clamping concave block 230 installed on the bidirectional screw 221 engages with the clamping protrusion 240. The clamping distance between the clamping protrusion 240 and the clamping concave block 230 is adjusted, so that the V-shaped clamping groove between the two is changed, so that the V-shaped clamping groove can match and clamp different shapes, so as to clamp the workpiece more stably.

[0025] Working principle: Pulling the pull rod 150 causes the pull rod 150 to drive the insertion rod 141, which moves and compresses the compression spring 151 in the mounting sleeve 140, causing the insertion rod 141 to move out of the positioning groove 120. This releases the insertion rod 141 from locking the rotating rod 130. Then, rotating the rotating rod 130 causes the rotating plate 110 to rotate, allowing the clamping mechanism to clamp the workpiece. After clamping, releasing the pull rod 150 causes the compression spring 151, which was compressed by the insertion rod 141, to extend and push the insertion rod 141 to move, inserting it into the positioning groove 120 and locking the rotating rod 130. This, in turn, locks the rotating plate 110 connected to the rotating rod 130.

[0026] According to the clamping requirements, the bidirectional screw 221 connected to the drive rod 220 is rotated by rotating the drive rod 220, so that the clamping concave block 230 installed on the bidirectional screw 221 engages with the clamping protrusion 240. The clamping distance between the clamping protrusion 240 and the clamping concave block 230 is adjusted, so that the V-shaped clamping groove between the two is changed, so that the V-shaped clamping groove can match and clamp different shapes, so as to clamp the workpiece more stably.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
