[0001] The present application relates to the technical field of clamping equipment, in particular to a compact integrated guide rail clamp. BACKGROUND

[0002] The common clamping methods in the current industrial processing are manual clamping, pneumatic clamping and hydraulic clamping. Although manual clamping has low cost and wide application, the clamping force is uncertain, the labor intensity is large and the clamping precision is not enough. Therefore, pneumatic clamping and hydraulic clamping are often used in processing. The pneumatic clamping has low and unstable clamping force, so the work is unreliable. The hydraulic clamping often needs a complex hydraulic system, so the application range is limited and the reaction speed is slow.

[0003] The guide rail clamp is a clamp used for clamping and fixing the guide rail. The existing guide rail clamp is mostly driven by hydraulic clamping, which has the advantage of high clamping force. However, it needs to be connected with a hydraulic system during use, and the clamp has a large volume, which is not convenient to carry and install. In addition, the reaction speed of the hydraulic system is slow during use, which leads to a long time for clamping and taking out the workpiece, greatly affecting the work efficiency. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art, such as slow reaction speed and large equipment volume of the guide rail clamp using hydraulic pressure as the driving force.

[0011] Further, the locking device comprises a stop piston chamber coaxially arranged with the through hole, one end of the stop piston chamber is provided with a sealing cover, the other end is communicated with the through hole, a locking piston is arranged in the stop piston chamber, and a hydraulic chamber connected with the oil storage bin is formed between the locking piston and the sealing cover.

[0012] Further, the end of the hydraulic chamber connected with the through hole is provided with a locking chamber, and the locking chamber gradually reduces in diameter from the hydraulic chamber to the through hole.

[0013] Further, the locking piston comprises a plunger slider arranged in the hydraulic chamber and a locking spring sheet arranged in the locking chamber, and the locking spring sheet gradually reduces in diameter from one end connected with the plunger slider to the outside.
