Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described further.
As shown in figure 1, the multidirectional clamping tool that links of this mechanical screwing type includes support base 1, hook pressure plate 2, compresses spiral shell Bolt 3, clamp nut 4 and pressing plate back-moving spring 5.
Described 3 one end of hold-down bolt is fixedly connected in support base 1, the other end is down-set through hook-shape structure The installing hole of hook pressure plate 2 is connected with 3 screw thread of hold-down bolt, and the hook-shape structure of hook pressure plate 2 corresponds to the pressure of L-shaped workpiece 6 Tight position;Described pressing plate back-moving spring 5 is socketed on hold-down bolt 3, one end is acted against in support base 1, the other end is leaned On hook pressure plate 2.
In described support base 1, the position of corresponding L-shaped workpiece 6 is provided with auxiliary positioning mouth 11;Set in auxiliary positioning mouth 11 There is arc-shaped limit pressing plate 12 being vertically arranged, being hingedly mounted in auxiliary positioning mouth 11, arcuate structure;It is located at auxiliary positioning Corresponding 12 bottom of arc-shaped limit pressing plate inside support base 1 on the inside of mouth 11, below 12 pin joint of arc-shaped limit pressing plate Position be provided with horizontally disposed act against 12 lower position of arc-shaped limit pressing plate, wear the wedge shape being connected on inside support base 1 and pass Dynamic pin I 13, wedge shape trundle I 13 are located at the tapered ramp structure that the one end inside support base 1 is provided with above-below direction setting, wedge On shape trundle I 13, also socket is provided with wedge pin back-moving spring 14, and 14 one end of wedge pin back-moving spring acts against support base 1 The upper, other end is acted against on wedge shape trundle I 13;Inside support base 1, correspondingly wedge shape I 13 wedge shapes of trundle are oblique for vertical direction The position of face structure is provided with wears the wedge shape trundle II 15 being connected on inside support base 1, and the bottom of wedge shape trundle II 15 is provided with With the tapered ramp structure of the tapered ramp respective outer side edges of wedge shape trundle I 13, the top of wedge shape trundle II 15 passes support Base 1 is simultaneously acted against on the baseplane of hook pressure plate 2.
Support base 1 is first fixedly mounted on lathe frock when using by the multidirectional clamping tool that links of this mechanical screwing type On table top, as shown in figure 1, and then snapping in down-set for the L-shaped structure minor face of L-shaped workpiece 6 in auxiliary positioning mouth 11 and inwardly Side shifting acts against the long side of the L-shaped structure on the inwall of auxiliary positioning mouth 11, hook pressure plate 2 being crimped on L-shaped workpiece 6 then On, finally progressively screw clamp nut 4;Hook pressure plate 2 is driven to move down compression pressing plate back-moving spring in 4 screwing operations of clamp nut 5 and the hook-shape structure of hook pressure plate 2 is made to compress the long side of L-shaped structure of L-shaped workpiece 6, while band in 2 folding process of hook pressure plate Dynamic wedge shape trundle II 15 is vertically moved down, wedge shape trundle II 15 coordinates promotion wedge shape trundle I by tapered ramp 13 ejection compression wedge pin back-moving spring 14 make arc-shaped limit pressing plate 12 be hinged center along which to turn clockwise, arc laterally In spacing 12 rotary course of pressing plate of shape, its top leans the L-shaped structure minor face of L-shaped workpiece 6 and acts against auxiliary to medial movement is firm On the inwall of positioning port 11 and apply clamping force, so realize hook pressure plate 2 and arc-shaped limit pressing plate 12 and meanwhile produce clamping force, Realize the Bidirectional clamping to L-shaped workpiece 6.
Dismounting clamp nut 4 is reversely rotated after completion of processing, hook pressure plate 2 under the elastic force effect of pressing plate back-moving spring 5 Move up reset and depart from L-shaped workpiece 6, at the same under the elastic force effect of wedge pin back-moving spring 14 I 13 retraction of wedge shape trundle, And coordinate promotion wedge shape trundle II 15 to move up reset by tapered ramp, take out the L-shaped workpiece 6 for processing.
In order to when clamp nut 4 is unclamped arc-shaped limit pressing plate 12 can from master reset, as of the present utility model enter one Step improvement project, the bottom of described arc-shaped limit pressing plate 12 is provided with arc-shaped limit pressing plate reset tension spring 16, arc-shaped limit pressing plate 16 one end of reset tension spring is connected with the bottom of arc-shaped limit pressing plate 12, the other end be located at I 13 side of wedge shape trundle support Base 1 connects, and when clamp nut 4 is unclamped, arc-shaped limit pressing plate reset tension spring 16 can pull arc-shaped limit under elastic force effect Pressing plate 12 makes which around its jointed shaft spinning reduction.
In order to prevent II 15 transition of wedge shape trundle from moving down disengaging wedge shape trundle I 13 during clamp nut 4 is screwed Tapered ramp structure so that stuck cannot reset, as further improvement of the utility model scheme, described support base On 1, the position of corresponding II 15 side of wedge shape trundle is provided with the location hole and installation arranged along II 15 radial direction of wedge shape trundle Alignment pin 17 on location hole, on described wedge shape trundle II 15, the position of corresponding alignment pin 17 is provided with along wedge shape trundle The locating slot that II 15 axial directions are arranged;During screwing clamp nut 4, wedge shape trundle II 15 is vertically displaced downwardly to locating slot top After end is acted against on alignment pin 17, wedge shape trundle II 15 stops moving down, and unclamps wedge shape trundle II during clamp nut 4 15 vertically on move to wedge shape trundle II 15 after locating slot bottom is acted against on alignment pin 17 stop on moving.
The multidirectional clamping tool that links of this mechanical screwing type is as the position of corresponding L-shaped workpiece 6 in support base 1 is provided with auxiliary Positioning port 11, is provided with, in auxiliary positioning mouth 11, the arc-shaped limit pressing plate 12 for being hinged setting, and on the inside of auxiliary positioning mouth 11 It is provided with inside support base 1 and acts against the wedge shape trundle I 13 of 12 bottom of arc-shaped limit pressing plate, is vertically arranged in support base 1 Internal II 15 bottom of wedge shape trundle is coordinated with the tapered ramp structure tapered ramp of wedge shape trundle I 13, is therefore being compressed Wedge shape trundle II 15 is driven to move down by wedge shape while hook pressure plate 2 moves down compression L-shaped workpiece 6 in 4 screwing operations of nut Inclined-plane coordinates makes arc-shaped limit pressing plate 12 rotatably compress L-shaped workpiece 6, Jin Ershi along its jointed shaft the ejection of wedge shape trundle I 13 Existing hook pressure plate 2 and arc-shaped limit pressing plate 12 produce the Bidirectional clamping of clamping force, realization to L-shaped workpiece 6, this Bidirectional clamping simultaneously Clamping force screw action from a clamp nut 4, therefore clamping force is uniform, positioning is simple, clamp labour intensity relatively Little, and clamping is firm, can prevent the L-shaped workpiece 6 of centering positioning from misplaced in clamping process again, and then ensure to determine Position effect and machining accuracy, are particularly well-suited to clamp the template workpiece with right angle or corner structure.
