Problems solved by technology
[0003] However, most of the existing fixtures for hydraulic machine tools have a single structure, which only drives two clamping plates to clamp the two ends of the workpiece through a two-way screw rod. When this kind of fixture is suitable for ordinary rectangular plates The workpiece can be clamped stably, but when clamping the workpiece with irregular shape, because the clamping surface of the two clamping plates is a plate structure, the contact area between the clamping plate and the workpiece with irregular shape Smaller, the workpiece will be damaged and cannot be clamped stably when it is clamped forcibly, and it cannot be clamped stably when clamping a thinner plate-shaped workpiece

The invention relates to the field of hydraulic machine tool clamps, in particular to a clamp for a hydraulic machine tool. The clamp comprises a supporting assembly, a transmission assembly, an air pressure clamping assembly and a pressing clamping assembly, the transmission assembly is arranged below the supporting assembly, and the air pressure clamping assembly and the pressing clamping assembly are symmetrically arranged at the four corners of the top of the supporting assembly in pairs. Through the transmission assembly arranged at the bottom of the supporting assembly, when a workpieceis clamped and a first rotating shaft in the transmission assembly rotates, a second bevel gear and a third bevel gear can be driven to rotate through a first bevel gear; and when the third bevel gearand the second bevel gear rotate, a first fixing plate and a second fixing plate which are in threaded connection with a first lead screw and a second lead screw can be driven to move in the oppositedirections, the first fixing plate and the second fixing plate can drive a first clamping plate and a second clamping plate to move in the opposite directions through a first sliding block and a second sliding block, and the clamping plates on the clamp can be adjusted more conveniently.
Description
technical field [0001] The invention relates to the field of clamps for hydraulic machine tools, in particular to a clamp for hydraulic machine tools. Background technique [0002] A hydraulic lathe refers to a lathe that uses hydraulic tooling. It can drive different tool holders to move according to specified commands through oil cylinders, and can realize automatic processing of workpieces. When using a hydraulic machine tool to process a workpiece, in order to enable the workpiece to be stably processed by the machine tool, it is necessary to clamp the workpiece with a practical fixture. [0003] However, most of the existing fixtures for hydraulic machine tools have a single structure, which only drives two clamping plates to clamp the two ends of the workpiece through a two-way screw rod. When this kind of fixture is suitable for ordinary rectangular plates The workpiece can be clamped stably, but when clamping the workpiece with irregular shape, because the clamping ...
