Description

A kind of clamping tooling for flat-type part

Technical field

The utility model relates to auxiliary mould field more particularly to a kind of clamping toolings for flat-type part.

Background technique

When processing in machining to the end face of flat-type part, common method is to use the auxiliary moulds such as pressing plate The end face of flat-type part is pushed down, to realize the positioning of flat-type part, then the end face of flat-type part is processed；This The method that kind positions flat-type part, since it is desired that pressure sets the end face of flat-type part, so when needing to flat-type part Entire end face when all being processed, be necessarily required to unclamp pressing plate, change position of the pressing plate on flat-type part end face, then weigh Newly pressing plate compression is continued to process, this means that needing in the process of same end face to flat-type on flat-type part Part carries out multiple clamping centering, and requires just to will affect the plane of the end face processed again to knife after centering every time Degree and roughness equally accurate reduce processing quality；

And if the auxiliary for being contacted with the end face of flat-type part without using pressing plate etc., and flat-type part being compressed downwards Tooling is changed to the tooling for being contacted with the side of flat-type part using withstanding tight block etc., and flat-type part being held out against from side, because Lack downward active force for the power only held out against from side to flat-type part, so holding during processing end face Easily make flat-type part because cutter shear action power and there is a situation where certain side tilt, cause flat-type part without legal Position carry out processing can not；

In order to overcome the problems referred above, magnechuck can be used, magnechuck is first pressed downward tightening position, then by flat-type zero Part is placed on magnechuck, flat-type part is sucked downwards by the electromagnetic action of magnechuck, to can overcome cutter Shear action power, realize processing in clamped one time to the entire end face of flat-type part；But the area of magnechuck has Limit can not be suitable for the flat-type part of all size shape, and the suction-operated of magnechuck is also by used in flat-type part The limitation of material, it is expensive inconvenient, cause magnechuck to be difficult to promote and apply in the actual processing of flat-type part.

Utility model content

To solve the problems, such as above-mentioned existing flat-type part processing, the utility model provides a kind of for putting down The clamping tooling of plate parts, can to the side of flat-type part carry out obliquely hold out against positioning.

Used technical solution is the utility model to solve above-mentioned technical problem: a kind of folder for flat-type part Tooling is held, further includes a right-and-left screw and two including one for being fixedly mounted on the fixed block of flat-type part side It is a to twist the withstanding tight block being located on oppositely oriented two sections of right-and-left screw respectively, the waist being obliquely installed is offered on the fixed block Shape through-hole, the right-and-left screw level are threaded through in waist through hole, and at least one section of sliding bevel is equipped on two withstanding tight blocks, Sliding bevel on same withstanding tight block is parallel to each other, and the inclined direction of the sliding bevel on different withstanding tight blocks is symmetrical arranged, described Fixed block is equipped with multistage respectively with each section of one-to-one guiding surface of sliding bevel, is rotated by right-and-left screw and each Section sliding bevel is bonded with respective guiding surface respectively, makes axial reversed horizontal fortune of two withstanding tight blocks along right-and-left screw It is dynamic, while two withstanding tight blocks being made to slide along guiding surface and right-and-left screw is driven to slide in waist through hole；

The intersection for defining guiding surface and any level datum level is the horizontal base line of guiding surface, and all horizontal base lines are equal Be obliquely installed with right-and-left screw, make two withstanding tight blocks along the axial direction of right-and-left screw when close to each other along the sliding of guiding surface Withstanding tight block and right-and-left screw can be made along the direction perpendicular to right-and-left screw close to flat-type part；

Define guiding surface with arbitrarily perpendicular to the intersection of the vertical datum level of right-and-left screw be guiding surface it is vertical Baseline, all vertical baselines are obliquely installed with vertical direction, keep withstanding tight block close along the direction perpendicular to right-and-left screw Sliding when flat-type part along guiding surface can make withstanding tight block generate the movement along guiding surface diagonally downward；

The inclined direction of the waist through hole is matched with the direction of withstanding tight block banking motion, in order to which right-and-left screw is with top Tight block banking motion, to enable withstanding tight block along direction perpendicular to right-and-left screw and diagonally downward close to flat-type zero Part, and the side of flat-type part is held out against obliquely.

Preferably, two sections of sliding bevels, two sections of sliding bevels on same withstanding tight block are equipped on described two withstanding tight blocks It is located at right-and-left screw two sides.

Preferably, the fixed block includes one section of protrusion, the width of the protrusion close to one end of flat-type part Width less than fixed block far from flat-type part one end, the waist through hole are provided on protrusion, described two withstanding tight blocks It is located at protrusion two sides.

Preferably, multiple fixation holes that fixed block displacement is limited for wearing fastener are offered on the fixed block.

According to the above technical scheme, the beneficial effects of the utility model are:

A kind of clamping tooling for flat-type part provided by the utility model, when in use can be by multiple toolings point It is not fixed on the different side of flat-type part, by rotating right-and-left screw, two withstanding tight blocks can be made along right-and-left screw It is axial move backward and slided along guiding surface, by the setting of guiding surface and sliding bevel inclined direction, make two Withstanding tight block can move simultaneously close to flat-type part when adjacent to each other along direction diagonally downward, while make left-right rotary spiral shell Bolt slides in waist through hole, so that two withstanding tight blocks be made to contact with the side of flat-type part, and by the one of flat-type part Skew back is held out against downwards, is clamped each side of flat-type part together by the cooperation of multiple toolings and is held out against, can be achieved with plate The positioning of class part；Compared with using pressing plate or withstanding tight block in the prior art, because the utility model is from side by flat-type Part is held out against obliquely, so the processing that frock clamp contacted and influenced end face with the end face of flat-type part will not occur, is led It causes to need to carry out multiple clamping centering in the processing of an end face and the case where to knife, and the utility model passes through to flat-type The active force of part side obliquely eliminates the trend that the shear action power of cutter makes flat-type part be upturned, thus Make flat-type part that can smoothly complete the processing of entire end face by clamped one time, be conducive to the flatness for promoting end face and Roughness equally accurate guarantees processing quality；The utility model and scope of application is small and structure is complicated that expensive electromagnetism is inhaled Disk is compared, and is applicable not only to the flat-type part of full range of sizes and a variety of materials, and structure be simply convenient for manufacture and Transhipment, cost is also far below magnechuck, only needs for the utility model to be fixed on flat-type part side when in use and is rotated further by Right-and-left screw, it is easy to operate, a variety of disadvantages of magnechuck in actual use are overcome, suitable for promoting the use.
