Description

Technical Field

[0001] The utility model relates to the technical field of mechanical clamping devices, and particularly relates to a quick clamping device. Background Technique

[0002] In a fixture, a device used to prevent a workpiece from displacing or vibrating during machining is called a clamping device. The following requirements should be considered when designing a clamping device:

[0003] 1. Do not change the position of the workpiece during the clamping process.

[0004] 2. The clamping force should be such that it can ensure that the workpiece does not displace or vibrate during machining, and does not damage the surface of the workpiece or cause deformation.

[0005] 3. Easy to operate, quick clamping action to improve productivity; simple structure, easy to manufacture to reduce the cost of the fixture.

[0006] 4. Can self-lock, that is, after the original force is removed, the clamped state of the workpiece can still be maintained.

[0007] 5. Safe operation, low labor intensity.

[0008] The clamping device has three functions: opening and closing the mold, ejecting the plastic part, and having sufficient force to keep the mold closed during injection to resist the pressure of the melt in the mold. The clamping force required per unit projected area of the part is usually 30 - 70 MPa (about 2 - 5 t / in2). The pressure generated during filling and the force generated on the core due to part shrinkage may cause the part to stick, thus making it difficult to separate the two half molds. The magnitude of the initial mold opening force depends on the filling pressure, the geometric dimensions of the material part (depth and draft angle), and is approximately equal to 10% - 20% of the nominal clamping force.

[0009] At present, clamping devices are widely used in industry and daily life. However, the clamping of many clamping devices is relatively cumbersome, and generally, a clamping device only has one clamping method. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Content of the Utility Model

[0010] The purpose of the present utility model is to provide a quick clamping device. Above the inner part of the bottom base of the quick clamping device body, there is a main body support column. Above the main body support column, there is a rotating column head. At the end of the connecting shaft in the center of the rotating column head, there is a top mating installation block. On both sides of the top mating installation block, there are symmetrically arranged cylinder A and cylinder B. Between cylinder A, cylinder B and the top mating installation block, there are mating locking positioning blocks. On one side of the top mating installation block, there is an induction head. On the top of the top mating installation block, there are a mating installation block and a top fixing block. Below one end of the mating installation block, there is a mating clamping plate. Between the bottom end of the clamping plate and the mating installation bracket on the outer wall of the main body support column, there is a connecting column. When clamping materials, first screw the product into the transition connecting head, and then insert it into the hole. After the sensor above the induction head senses it, the two cylinders automatically clamp it. The clamping speed is fast and the operation is convenient.
