Description
Technical field
The utility model belongs to bench vice technical field, is specifically related to a kind of hand-hydraulic bench vice.
Background technology
Bench vice is the indispensable instrument of pincers worker, usually be used to carry out effectively firm fixing to workpiece, common bench vice mainly comprises fixing clamp block and activity clamp block, workpiece is then located in the jaw between fixing clamp block and activity clamp block, activity clamp block moves towards fixing clamp block via the rotation of a rotary actuation bar, thus making workpiece be held between fixing clamp block and activity clamp block, workpiece just can be processed after being fixedly clamped.Above-mentioned bench vice structure is simple, easy to use, is widely used in field of machining.But also there are some defects in this type of bench vice, as clamp as described in workpiece time, need continuous rotary actuation bar to adjust the size between fixing clamp block and activity clamp block, then being exerted pressure by manpower makes workpiece be clamped, and workpiece is when loosening, also need same manpower to adjust jaw to complete loosening of workpiece, this mode wastes time and energy when holding workpiece, inefficiency during use, and easily make clamping force too small and following process or the excessive infringement that workpiece is caused of clamping force can not be carried out by clamping work pieces.
Utility model content
The purpose of this utility model is for the problem existing for existing bench vice, and provides that a kind of clamping speed is fast, service efficiency is high, and chucking power is stablized, and can control chucking power and can not to the hurtful hand-hydraulic bench vice of workpiece according to the workpiece of different size.
The purpose of this utility model realizes by following technical proposal:
A kind of hand-hydraulic bench vice, comprise base, regular jaw and moving jaw, regular jaw and moving jaw are arranged in opposite directions on base and also form jaw between, regular jaw is fixedly connected with base, moving jaw can move back and forth relative to regular jaw, it is characterized in that, described moving jaw is provided with relative to the opposite side of regular jaw and drives its drive unit moved back and forth, described drive unit comprises hydraulic cylinder, gear, tooth bar and clamping screw, the piston rod of hydraulic cylinder stretches out from cylinder body and docks with tooth bar and is connected, tooth bar is provided with teeth and vertical with clamping screw, the front end of clamping screw is threaded with moving jaw, gear to be arranged on screw rod and to engage with above-mentioned tooth bar, hydraulic cylinder is provided with hand-control device.
Driven by Hydraulic Cylinder piston rod stretches, piston rod band carry-over bar moves back and forth, due to wheel and rack engagement, gear and then rotates back and forth, and drive the clamping screw be fixed in above it to rotate back and forth together, the front end of clamping screw is threaded with moving jaw, and it drives the relative regular jaw of moving jaw to move back and forth, thus reaches the object clamping and unclamp workpiece.
In above-mentioned a kind of hand-hydraulic bench vice, the afterbody of described clamping screw is provided with adjusting handle.Adjusting handle can be used for finely tuning moving jaw.
In above-mentioned a kind of hand-hydraulic bench vice, described hand-control device comprises switching valve and turning handle, and turning handle drives switching valve to rotate.Change the pressure oil path of hydraulic cylinder, the duty of hydraulic control cylinder.
In above-mentioned a kind of hand-hydraulic bench vice, described tooth bar, clamping screw and gear are arranged in gear-box, and the sidepiece of gear-box is provided with the opening just right with tooth bar, and opening part is provided with dust cap by securing member.
Compared with prior art, the utility model is owing to being provided with hydraulic cylinder, gear, tooth bar and the clamping screw drive unit as moving jaw, the clamping speed of bench vice is speeded, operating efficiency improves, when hand-hydraulic is adjusted to a certain degree, carry out fine adjustment by adjusting handle again, thus can not cause damage to workpiece.
