Pressure-adjusting structure for double-force-type vice

Abstract

The invention discloses a pressure-adjusting structure for a double-force-type vice. The pressure-adjusting structure is composed of a vice unit, a transmission unit, an adjusting unit and a double-force unit. A push rod of the adjusting unit is arranged in a guide screw in a penetrating mode, a thread sleeve is arranged at the end of the guide screw in a threaded mode, and thus a second elastic element pushes against a pressing block; a clutch ring is arranged on the periphery of the guide screw in a sleeving mode, and provided with a plurality of axial adjusting grooves with different lengths, and a radial sliding oblique groove is arranged among the axial adjusting grooves in a connected mode. The axial adjusting grooves allow an embossment of the guide screw to move relatively, a driving tube is arranged in the thread sleeve in a threaded mode, and the end of the driving tube pushes against the push rod. An adjusting ring is fixedly connected with the clutch ring through a bolt soas to be integrally linked with the clutch ring, and thus the pressure-adjusting structure can adjust of the pressure increasing amount in a multi-stage mode and easily slides into the axial adjustinggrooves, and operation is simple, easy and effortless.

Description

technical field [0001] The invention relates to the technical field of a double-force vise, in particular to a pressure-regulating structure of a double-force vise. Background technique [0002] China Taiwan Announcement No. M300156, an improved booster adjustment structure of a double force vice, mainly forms a multi-stage adjustment part by rotating the predetermined position of the wall surface of the clutch ring, and a sliding part and a multi-stage adjustment positioning part are formed in the multi-stage adjustment part. In addition, the sliding part is in the form of a radial section space, and the adjustment and positioning parts of each section are respectively in the section space form of different axial depths, and the sliding part is connected to the adjustment and positioning parts of each section with different axial depths; thereby , can achieve multi-stage selective, fast and accurate adjustment of the distance from the end of the drive cylinder, and control ...

Problems solved by technology

[0003] Although these structures can adjust the supercharging force in multiple stages, the sliding part and the multi-stage adjusting and positioning parts are connected in a radial and axial direction at 90 degrees, and it is not easy to slide into the sliding part from one of the adjusting and positioning parts. , and then enter the set adjustment and positioning part, it is easy to cause interference and difficult to operate, and the operation process is laborious and inconvenient. In addition, these structures do not have the clamping effect of double force boosting, so that the clamping force of the workpiece It will still be limited, so it is necessary to further improve it due to the various deficiencies that are known.
