Description

A kind of efficient positioning and clamping mechanism
Technical field
It is specifically a kind of to carry out the positioning clamping machine of efficient quick change workpiece the invention belongs to machinery manufacturing technology field Structure.
Background technology
In mechanical processing process, the positioning and clamping of workpiece is an extremely important link, is related to workpiece accuracy, life Produce the multinomial key elements such as safety, processing efficiency.The positioning and clamping mode of workpiece is divided into manual clamping and the class of automated exchanged cutter two, based on into Originally, complexity and workpiece demand consider, manual installation way is only discussed.
Using two-way push positioning, helical clamping mode more than current manual clamping, after limitation workpiece six-freedom degree, according to The clamping force provided is fed by screw thread and is securely fixed workpiece, typically has vice, pressing plate etc., this is also that general factory is the most frequently used Fixture be equipped with.Unclamp and clamp workpiece, be required to rotate screw thread, slow motion, efficiency is low, to high-volume, small size and cutting The little workpiece of power is but difficult to play very big effect, it is therefore desirable to find a kind of efficient positioning and clamping mechanism of replacement to meet Efficiency requirements.
The content of the invention
The technical problem to be solved
In order to avoid the shortcomings of the prior art, the present invention proposes a kind of efficient positioning and clamping mechanism, it is small to solve Clamping efficiency when type workpiece high-volume is processed.
Technical scheme
A kind of efficient positioning and clamping mechanism, it is characterised in that including pedestal, locating piece, tapered wedges, briquetting, compression spring, Adjusting screw and holding screw;Described pedestal is provided with group hole, circular hole, first hole and second hole, wherein the one of group hole Hold as circular hole, the other end is square hole, adjusting screw is arranged on the circular hole end in group hole, and tapered wedges are arranged on the square hole end in group hole, Compression spring is installed between adjusting screw and tapered wedges;First hole intersects vertically with group hole, second hole and group hole, first party Kong Jun intersects vertically, and briquetting loads from second hole and contacted with tapered wedges, and workpiece is encased in first from one end of first hole On one Angle Position of square hole, briquetting is by Work-sheet pressing, and locating piece loads from the other end of first hole and is located at workpiece same One Angle Position;Circular hole is parallel with group hole and is intersected vertically with first hole, and holding screw is arranged in circular hole, for holding out against positioning Block.
The inclined-plane that described briquetting is contacted with tapered wedges is 30 °~60 °.
Beneficial effect
A kind of efficient positioning and clamping mechanism proposed by the present invention, compared with conventional fixture, its advantage is mainly reflected in Following two aspects:
(1) work speed is changed fast.In clamping process, left hand only needs to perform holddown spring and release spring action, And the right hand performs the action for loading workpiece and unloading workpiece simultaneously, it can complete within several seconds.
(2) clamping force is adjustable, meets different cutting force workpiece demands.

Embodiment
In conjunction with embodiment, accompanying drawing, the invention will be further described:
Technical scheme is as follows:
1) Position Design
According to principle of six-point fixing, therefore using two vertical planes of workpiece longitudinal direction as positioning datum, one of face is used as master Positioning datum is wanted, another face so limits five frees degree of ring rod, last freedom as guide-localization benchmark Degree is then given by the increased adjustable positioning block in workpiece bottom to be limited, and so meets positioning requirements.
2) clamping device
The clamping device structure of fixture is made up of following two parts.
(1) power set-generation clamping force:When considering clamping force source, we have selected spring clamp mode.Cause This, fixture provides clamping force using spring.
(2) clamp system-transmission clamping force:Power produced by making spring is correctly applied on workpiece, must just be had Appropriate transmission mechanism, plays the mechanism of the transmission of power in clamping process, and the clamp system is in the process of transmission power In, size, direction and the application point of power can be changed as needed.According to mentioned above principle and the positioning needs of product, using leading Clamping force is delivered on workpiece to part-tapered wedges and briquetting.
(3) clamping force is adjusted:According to workpiece demand, clamping force size can be adjusted.An adjusting screw is designed during regulation, Decrement for adjusting spring, workpiece clamp clamp force is adjusted in this way.
Referring to accompanying drawing 1, pedestal 1 of the present invention, locating piece 2, tapered wedges 3, briquetting 4, compression spring 5, adjusting screw 6 and tightening Screw 7;Described pedestal 1 is provided with group hole 9, circular hole 10, first hole 11 and second hole 12, wherein the one end in group hole 9 is Circular hole, the other end is square hole, and adjusting screw 6 is arranged on the circular hole end in group hole 9, and tapered wedges 3 are arranged on the square hole end in group hole 9, Compression spring 5 is installed between adjusting screw 6 and tapered wedges 3;First hole 11 intersects vertically with group hole 9, second hole 12 and group Hole 9, first hole 11 intersect vertically, and briquetting 4 loads from second hole 12 and contacted with tapered wedges 3, and workpiece 8 is from first hole 11 one end is encased on an Angle Position of first hole 11, and briquetting 4 compresses workpiece 8, and locating piece 2 is from first hole 11 The other end loads and is located at same Angle Position with workpiece 8;Circular hole 10 is parallel with group hole 9 and is intersected vertically with first hole 11, tightly Screw 7 is determined in circular hole 10, for holding out against locating piece 2.
Tapered wedges 3 carry step surface, and briquetting 4 is placed on the step surface of tapered wedges 3;Both are necessary for inclined-plane at side joint contacting surface, Angle is optimal with 45 ° in 30 °~60 °;Briquetting 4 is with the contact surface shape of workpiece 8 according to depending on the shape of workpiece 8;Briquetting 4 length determines criterion:Afterbody can stretch out pedestal 1 by second hole 12 when taking workpiece 8, that is, ensure when taking workpiece 8, press Block 4 is also partly exposed at second hole 12 and existed, and is easy to operate briquetting 4 outside pedestal 1.
By changing amount of spring compression, the energy of spring store is converted into pressure, and transmit by tapered wedges 3, briquetting 4 Onto workpiece 8, the clamping force to workpiece 8 is formed.
Locating piece loads pedestal, the one-movement-freedom-degree for controlling one direction of workpiece;Briquetting, tapered wedges, compression spring Pedestal is sequentially loaded into adjusting screw, one-movement-freedom-degree and three rotary freedoms for controlling two other direction;Adjust Whole screw can be preconditioned to clamping force.
Its implementation process is as follows:
When dismantling workpiece 8, adjusting screw 6 and tapered wedges 3 are pinned respectively with left hand thumb and middle finger, forefinger pins briquetting 4 Firmly, promote tapered wedges 3 to be moved along pilot hole, briquetting 4 moves release along inclined-plane, you can take out workpiece 8 simultaneously.
During clamping workpiece 8, adjusting screw 6 and tapered wedges 3 are pinned respectively with left hand thumb and middle finger, and forefinger pins briquetting 4 Firmly, promote tapered wedges 3 to be moved along pilot hole, briquetting 4 moves release along inclined-plane, then workpiece 8 is put according to machine direction simultaneously Enter the location of workpiece, until at the locating piece of lower section, then unclamping left hand, spring just promotes tapered wedges 3, briquetting 4 to clamp workpiece 8 simultaneously Positioning.
