Description

A kind of hydraulic clamping device
Technical field
The utility model belongs to mechanical fixture technology field, especially relevant with a kind of hydraulic clamping device.
Background technology
Scroll chuck is clamping device general in machining, existing hub-bearing unit blank adopts scroll chuck to clamp usually, existing scroll chuck generally can only clamp general workpiece, will there are the following problems during as clamped the special workpiece of certain pattern draft: 1, chucking power is little, during jaws clamp on scroll chuck, three claws and surface of the work can only form point contact type and clamp, need during turning to configure top increase chucking power, clamping comparatively bothers, and clamps less stable, affects the service life of scroll chuck simultaneously; 2, existing scroll chuck does not generally arrange axial direction positioning device, general realizes axial location by welding block on scroll chuck to workpiece, during as new in turnery processing workpiece, need again to weld, making block is wasted time and energy, and adds processing cost, clamping inefficiency.
Utility model content
The purpose of this utility model is intended to overcome existing clamping device when clamping the special workpiece of certain pattern draft, and the speed that clamps is comparatively slow and clamp unstable defect, provides a kind of and can clamp fast and the hydraulic clamping device of good stability.
For this reason, the utility model is by the following technical solutions: a kind of hydraulic clamping device, comprise scroll chuck and hydraulic jack, the clamping of scroll chuck or unclamp workpiece action and driven by hydraulic jack and realize, scroll chuck comprises chuck body and is distributed in three claws on chuck body end face, each claw is provided with a corresponding clamping face, it is characterized in that, each described clamping face forms taper seat by interior outward-dipping certain angle, each clamping face is provided with latticed chaste tree groove, the chucking power of claw is improved by the frictional force increased on clamping face, the leading section of each described claw end face outside is all provided with a corresponding position block, each position block is installed on corresponding each claw each via screw, the medial surface of each position block is the Workpiece fixing face of circular arc, each Workpiece fixing face is no more than described each corresponding clamping face, when guaranteeing that claw clamps workpiece, described position block carries out axial location to workpiece, prevent workpiece axial displacement, described position block can pass through screw disassembling, assembling and replacing.
Using the utility model can reach following beneficial effect: the taper seat 1, by being arranged to tilt from inside to outside by the clamping face of three claws, effectively the special workpiece of certain pattern draft can be housed stabilization clamp; 2, by installing a corresponding position block in the leading section of each claw end face outside, without the need to top protection, just can realize the axial location of workpiece, and position block can be changed, and reduces processing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises scroll chuck and hydraulic jack, the clamping of scroll chuck or unclamp workpiece action and driven by hydraulic jack and realize, three claws 3 that scroll chuck comprises chuck body 4 and is distributed on chuck body end face 5, each claw 3 is provided with a corresponding clamping face, each described clamping face forms taper seat by interior outward-dipping certain angle, each clamping face is provided with latticed chaste tree groove 2, the chucking power of claw 3 is improved by the frictional force increased on clamping face, the leading section of the end face outside of each described claw 3 is all provided with a corresponding position block 1, each position block 1 is installed on corresponding each claw 3 each via screw, the medial surface of each position block 1 is the Workpiece fixing face 6 of circular arc, each Workpiece fixing face 6 is no more than described each corresponding clamping face, when guaranteeing that three claws 3 clamp workpiece, described position block 1 pair of workpiece carries out axial location, prevent workpiece axial displacement, described position block 1 can pass through screw disassembling, assembling and replacing.
