[0003] However, traditional clamping and breaking mechanisms typically use a cylinder connected to a clamping mechanism. Activating the cylinder causes it to push the clamping mechanism to secure the workpiece. To maintain the clamping state until the workpiece is broken, the cylinder needs to continuously apply a large force, causing it to operate for extended periods and resulting in a short lifespan. Utility Model Content

[0004] In view of the technical problems of the prior art, this utility model provides a force-increasing clamping and breaking mechanism.

Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] according to Figure 1-3 This utility model provides a force-increasing clamping and breaking mechanism, including: a base 1, a clamping block 2, a fixing block 3, a clamping cylinder 4, and a guide sleeve 5.

[0019] The clamping block 2 is slidably mounted on the base 1. The fixing block 3 is mounted on the base 1 on the side away from the clamping block 2. The fixing block 3 has a rotatable rotating block 32 on the side near the clamping block 2. The rotating block 32 has a rotatable rotating rod 33 on the side near the clamping block 2. The clamping block 2 has a rotatable rotating plate 23 on the side near the fixing block 3. The rotating plate 23 is rotatably fitted onto the rotating rod 33. The clamping cylinder 4 is connected to the rotating rod 33.

[0020] When clamping block 2 is needed to clamp the workpiece, clamping cylinder 4 is activated, causing rotating rod 33 to move away from clamping cylinder 4. When rotating rod 33 moves, rotating block 32 and rotating plate 23 will be driven. Since the length of rotating block 32 and rotating plate 23 will not change, the ends of both sleeved on rotating rod 33 will rotate relative to rotating rod 33. At the same time, the ends of both away from rotating rod 33 will move away from each other on base 1. Since fixed block 3 is set on base 1, fixed block 3 will not move, but rotating plate 23 will move away from fixed block 3, causing clamping block 2 to be pushed, so that clamping block 2 can clamp the workpiece. When clamping block 2 clamps the workpiece, rotating plate 23 and rotating block 32 are on the same straight line. That is, at this time, rotating plate 23 abuts against rotating rod 33, and rotating rod 33 abuts against rotating block 32, so that fixed block 3 supports clamping block 2. That is, at this time, fixed block 3 mainly applies force to clamping block 2 to keep clamping block 2 in a clamped state. After fixing, clamping cylinder 4 does not need to apply a large force, so the pressure on clamping cylinder 4 is small and the time of bearing large pressure is also less, thus reducing the wear of clamping cylinder 4.

[0021] The clamping block 2 includes: an abutment block 21 and a fastening block 22. The abutment block 21 has an abutment opening 211 on the side near the fastening block 22. The fastening block 22 has a fastening opening 221 on the side near the abutment block 21. The abutment opening 211 and the fastening opening 221 correspond to each other. A baffle 11 is provided at one end of the base 1. The baffle 11 abuts against the abutment block 21. A rotating plate 23 is rotatably disposed on the side of the fastening block 22 away from the baffle 11. The fixing block 3 also includes: a fixing seat 31. The fixing seat 31 is disposed on the base 1. The fixing seat 31 is fixed to the base 1. The rotating block 32 is rotatably connected to the base 1. The clamping cylinder 4 includes: a telescopic rod 41, a connecting block 42, and a housing 43. The connecting block 42 is connected to the telescopic rod 41. A perforated plate 421 is provided on the side of the connecting block 42 away from the telescopic rod 41. The perforated plate 421 is rotatably sleeved on the rotating rod 33. The telescopic rod 41 is movable relative to the base 1. The housing 43 is rotatably connected to the base 1. The housing 43 is rotatably connected to the fixed seat 31.

[0022] The clamping block 2 is divided into two parts: the contact block 21 and the fastening block 22. The two parts have contact openings 211 and fastening openings 221 on their respective sides. When they are combined, they form a circular hole. When it is necessary to clamp workpieces such as round tubes and round rods, the clamping cylinder 4 is activated to place the workpiece in the circular hole. At the same time, the rotating plate 23 drives the fastening block 22 to move toward the contact block 21 and make contact with the contact block 21. The contact block 21 then makes contact with the baffle 11, so that the fastening block 22 presses against the contact block 21. At the same time, the fastening opening 221 presses against the fastening opening 221, so that the workpiece in the circular hole is clamped. When the clamping cylinder 4 is started, the telescopic rod 41 extends and retracts, which in turn causes the connecting block 42 to extend and retract as well. This causes the perforated plate 421, which is fitted onto the rotating rod 33, to move the rotating rod 33. Since the fixed seat 31 remains stationary, the rotating block 32 is rotatably mounted on the fixed seat 31. If the housing 43 is stationary, the telescopic rod 41 and the connecting block 42 can only move in a straight line, while the length of the rotating block 32 remains unchanged and it can only rotate. Its trajectory on one side of the rotating rod 33 is an arc, which does not match the trajectory of the rotating rod 33 when it is driven. Therefore, this utility model allows the housing to rotate relative to the base 1 and the fixed seat 31, thereby enabling the rotating rod 33 to be driven, and its trajectory can match one side of the rotating block 32, thus ensuring the normal operation of this utility model.

[0023] The guide sleeve 5 is located on the side of the base 1 away from the clamping block 2. The guide sleeve 5 has a guide groove 51 on the side away from the base 1.

[0024] When in use, this utility model is fixed on the guide rail and moved to the corresponding breaking mechanism. Therefore, a guide sleeve 5 is provided on the side of the base 1 away from the clamping block 2. The guide sleeve 5 has a guide groove 51 corresponding to the guide rail. Through the guide sleeve 5, this utility model is fixed on the guide rail and moves along the guide rail, making it difficult for it to deviate, so that the position of the workpiece is more accurate when breaking.

[0025] Working principle and usage process of this utility model:

[0026] When it is necessary to clamp the workpiece, place the workpiece in the contact port 211, and then activate the clamping cylinder 4, so that the telescopic rod 41 moves away from the housing 43 and drives the connecting block 42, so that the rotating rod 33 is driven away from the housing 43. When the rotating rod 33 moves, it drives the rotating block 32 and the rotating plate 23 to rotate. At the same time, the housing 43 also rotates. When the rotating plate 23 rotates, it drives the fastening block 22 to move towards the contact block 21, so that the fastening port 221 is in contact with the contact port 211, and the contact block 21 abuts against the baffle 11, so that the workpiece is clamped by the fastening block 22 and the contact block 21. When the workpiece is clamped, the rotating plate 23 and the rotating block 32 are on the same straight line, so that the rotating plate 23 abuts against the rotating rod 33, and the rotating rod 33 abuts against the rotating block 32, so that the fixing block 3 supports the clamping block 2. Then, the present invention can slide to the designated position and pull off the workpiece.

[0027] In summary, this utility model utilizes the combined operation of multiple structures such as the clamping cylinder, the fixing block, and the base during clamping. This ensures that the fixing base primarily supports the clamping block during clamping, reducing the force and duration of the clamping cylinder, thus extending its service life.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
