Description

Technical Field

[0001] The utility model relates to the technical field of parallel clamps, in particular to a novel parallel clamp. Background Art

[0002] A device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection, also known as a fixture. In order for the surface of the workpiece to meet the technical requirements of size, geometry and relative position accuracy with other surfaces specified in the drawing, the workpiece must be mounted and clamped with a fixture before processing.

[0003] When the clamp is clamping the workpiece, due to the high hardness of the workpiece, the torque generated during the processing is large, and the existing clamps have insufficient clamping force, which can easily cause the workpiece to slip during processing, resulting in workpiece wear and reduced processing accuracy. In addition, the existing clamps occupy a large space, which causes inconvenience to the clamping of the workpiece. In response to the above problems, people invented patent number: CN202022023696.3, which discloses a hydraulic parallel clamp, which includes a fixed seat, a hydraulic cylinder and a connecting rod mechanism. The hydraulic cylinder is fixed on the fixed seat, and a driving block is arranged at the driving end of the hydraulic cylinder. The connecting rod mechanism includes a first connecting rod assembly including a fixed shaft, a rotating rod, a driving rod, a balancing rod and a pressing handle. The driving rod and the balancing rod are rotatably connected to the side of the driving block. When the hydraulic cylinder is started, the driving block can be driven to move. When the driving block moves forward, the driving rod can rotate counterclockwise under the drive of the rotating rod. When the driving rod rotates, the pressing handle can be driven to move toward the direction close to the driving block. When the pressing handle rotates, the balancing rod can be driven to rotate. The balancing block can stabilize the pressing handle to prevent the pressing handle from rotating. The workpiece can be clamped on the frame at the end of the pressing handle. Through the above structural arrangement, the clamping force of the clamp can be effectively improved, and at the same time, the space utilization rate of the clamp can be improved, which facilitates the installation of the workpiece. However, the parallel clamp still has the following problems: 1. The parallel clamp has a complex structure, and it uses multiple components to form a linkage, which increases the manufacturing cost and has a high failure rate of jamming, affecting the stability and life of the parallel clamp. In addition, the parallel clamp is large in size and cannot be used in a smaller space, which has certain limitations in use. Utility Model Content
