Description
Technical field
The present invention relates to Workpiece clamping device field, be specifically related to a kind of fixture of dovetail groove positioning clamping dual-workpiece.
Background technology
In machining, often need process multiple identical workpiece, such as milling workpiece plane, drill workpiece plane hole etc.If carry out clamping processing with a fixture to each workpiece, the clamping of each like this workpiece needs clamping, unclamps, and next workpiece clamps the process of unclamping and repeating so again.Such clamping mode efficiency is low, and labour intensity is large.
Publication number be CN204094513U patent discloses a kind of multi-workpiece fixture of machine tool, comprise pedestal, fixed block, movable block, cylinder guide post, one end are fixedly connected with the adjusting screw(rod) of handle, and recess is established in described fixed block both sides; Described fixed block is fixed on medium position on pedestal; Parallel gripper shoe is fixed at described base bottom two ends; Described cylinder guide post two ends are fixedly connected with in two gripper shoes; Second through hole of described adjusting screw(rod) two ends in two gripper shoes forms rotational structure together with bearing assemble; Described movable block has two and Parallel Symmetric is distributed in fixed block both sides; The square hole gap, upper end of two described movable blocks loads pedestal, and its bottom guide bar through hole and cylinder guide post coordinate and slide and engage with two sections of helicitic textures on adjusting screw(rod) respectively.
Owing to have employed, screw thread is set on adjusting screw(rod), mobile fast upper arrange match with screw flight screw thread to reach clamping effect.Meanwhile, just also needing, cylinder guide post is set and prevents mobile fast circumference from rotating, bearing is set at adjusting screw(rod) two ends and rotates to facilitate adjusting screw(rod).Like this, just cause its complex structure, cost is higher.
Summary of the invention
The object of this invention is to provide a kind of structure simple, the fixture of clamping dual-workpiece with low cost.
For solving complex structure in prior art, the problem that cost is higher, the base case of employing is as follows: a kind of fixture of dovetail groove positioning clamping dual-workpiece, comprising: pedestal, fixed block, left jaw, right jaw, regulating shaft; Wherein, described fixed block is arranged on the middle part of pedestal upper surface, and described pedestal is provided with the through hole of level, and described through hole runs through two non-conterminous vertical planes of pedestal, and described regulating shaft coordinates with via clearance; Described left and right jaw to be set on two ends that regulating shaft stretches out through hole and to adopt and is threaded, and the thread rotary orientation in being threaded of described regulating shaft is identical, and the thread rotary orientation in being threaded of described left and right jaw is contrary; Also comprise left and right spacer, the same of pedestal that be arranged on of described left and right spacer symmetry is not opened on the vertical plane in hole, described left and right spacer is provided with the trapezoidal rails of level, and described left and right jaw is provided with the dovetail groove matched with the trapezoidal rails of left and right spacer.
Operation principle and the beneficial effect of this base case are: after putting into two workpieces to be processed in left and right, rotate forward regulating shaft, setting rotates forward regulating shaft, left and right jaw relative motion, because regulating shaft and left and right jaw are for being threaded, and the thread rotary orientation that left and right jaw is threaded is contrary, so, left and right jaw is along driving shaft relative motion, and clamping work pieces.Because left and right spacer is provided with the trapezoidal rails of level, left and right jaw is provided with the dovetail groove matched with the trapezoidal rails of left and right spacer, so left and right jaw cannot rotate in the circumference of regulating shaft, and can move in the axis of regulating shaft.Adopt guide post different from prior art, owing to have employed dovetail groove slide unit structure.Do not need the supporting adn fixing device that guide post and guide post are set again, make this programme structure simple, with low cost.In addition, dovetail groove slide unit structure has the advantage that precision is high, gap is adjustable, bearing capacity is large, can be good at meeting need of production.
Preferred version 1, as the improvement to base case.Described fixed block is fixedly connected with pedestal by hexagon socket head cap screw.Advantage is, facilitates the dismounting of fixed block, can select the fixed block of different size and shape according to the geomery of part to be processed; In addition, due to the part that hexagon socket head cap screw is not given prominence to, so convenient, the upper surface of workpiece is processed.
Preferred version 2, as the improvement to base case.Also comprise handle, described handle is fixedly connected on regulating shaft one end.Advantage is, convenient operation is laborsaving.
Preferred version 3, as the improvement to base case.Described left and right spacer is fixedly connected with pedestal by screw.Advantage is, facilitates the dismounting of left and right spacer, can select the left and right spacer of different size according to the geomery of part to be processed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fixture of dovetail groove positioning clamping dual-workpiece of the present invention.
Detailed description of the invention
For making content of the present invention more become apparent, be described further below in conjunction with the drawings and specific embodiments.
Embodiment 1
As shown in Figure 1, a kind of fixture of dovetail groove positioning clamping dual-workpiece, comprising: pedestal 1, handle 3, regulating shaft 5, left jaw 7, left spacer 9, screw 11, hexagon socket head cap screw 13, right spacer 15, right jaw 17, dovetail groove slide unit 19, workpiece 100.
After putting into two workpieces to be processed 100 in left and right, rotate forward handle 3, regulating shaft 5 rotates forward, and (setting rotates forward regulating shaft 5, left and right jaw relative motion), because regulating shaft 5 and left and right jaw are for being threaded, and the thread rotary orientation that left and right jaw is threaded is contrary, so, left and right jaw is along the axial relative motion of regulating shaft 5, and clamping work pieces 100.Because left and right spacer is provided with the trapezoidal rails of level, left and right jaw is provided with the dovetail groove matched with the trapezoidal rails of left and right spacer, define dovetail groove slide unit 19, so left and right jaw cannot rotate in the circumference of regulating shaft 5, and can be free to slide in the axis of regulating shaft 5.
When after workpiece 100 completion of processing, backwards rotation handle 3, regulating shaft 5 backwards rotation, left and right jaw, along the axis of regulating shaft 5 from moving, unclamping workpiece 100, just can take out workpiece 100.
When the size of workpiece 100 changes, only need to unload hexagon socket head cap screw 13, just can change the fixed block 15 adapted with workpiece 100 size.Unload screw 11, just can change the left and right spacer that workpiece 100 size adapts.
