Description
Technical field
The utility model relates to a kind of frock clamp of workpiece pedestal porous processing, is applicable to volume large, processed complex, and there is the workpiece of angle in the many and relative datum in hole, belongs to field of machining.
Background technology
Pedestal is the strength member of certain product 1202 parts, the requirement of dimensional accuracy, form and position tolerance is all high, when former technics institution, numerical control device is also not universal, Special tooling clamp is (volume is large, heaviness) of formulating according to the feature of equipment at that time and the processing request of part, it is being meticulous and attending to minutes details in everything that everyway is considered, can complete throughput requirements at that time.But along with production equipment upgrades and the increase of product consumption day by day, original imperfect manufacture occurs gradually: labor strength is large, the process-cycle is long; The wearing and tearing of special tooling, the reason such as aging, dimensional accuracy and form and position tolerance are all difficult to ensure, need to rely on operator's experience to ensure; The problems such as special tooling quantity is many, and maintenance cost is large, are difficult to ensure completing smoothly of production in enormous quantities task.Utilize the advantages such as numerical control device intellectuality, processing variation, high accuracy, labour intensity be low to replace frock to complete boring, fraising and Profile milling and process, special tooling expense and workman's labour intensity is safeguarded in reduction.
Summary of the invention
The purpose of this utility model has been to provide a kind of frock clamp of workpiece pedestal porous processing, this frock clamp has been realized workpiece pedestal porous processing, easy disassembly, greatly reduce operator's labour intensity, ensure cylindricity and the perpendicularity in hole, avoid secondary clamping, improved product quality and production efficiency.
Technical solution:
The utility model comprises: body, and body bottom is provided with locating slot, and body sidewall is provided with bearing, on bearing, have the cell body that can make location-plate move, location-plate is shaped as inverse-T-shaped, and the straight bar part of location-plate is placed in cell body, on the upper surface of bearing, has screwed hole, location-plate is provided with horizontal draw-in groove, boss is established at handlebar middle part, and lower end is provided with screw thread, and the end of thread of handle is placed in screwed hole, boss on handlebar is placed in the horizontal draw-in groove of location-plate, and pressing plate is installed on bearing.
Further: body two side symmetry has bolt holddown groove, thus be convenient to bolt by reaching stationary fixture.
Further: bearing is shaped as " boss " shape, can save raw material, alleviates the weight of fixture, be convenient to installation, thereby play the effect of support positioning plates.
Further: body is provided with the chip-removal hole corresponding with workpiece working position, be mainly the discharge of being convenient to iron filings in the time carrying out processing parts.
The utility model location-plate is shaped as inverse-T-shaped, while being convenient to reverse handle, drives easily "T"-shaped location-plate, reaches with the locating surface of workpiece and contacts.
The utility model tool compared with original technology has the following advantages:
Original frock clamp is carrying out 3-￠ 8
+ 0.016, 3-￠ 41.6
+ 0.027, 3-￠ 16.003
+ 0.016, 3-￠ 16.64
+ 0.019this 12 hole add man-hour, need frock clamp two covers, and fixture heaviness, clamping complexity.In the large situation of processing parts volume, operator, in the time processing different holes, needs travelling workpiece, change positioning datum, labour intensity is very large, needs two people to coordinate, and be horizontal processing, the circularity in hole, perpendicularity are difficult to guarantee, and working (machining) efficiency is low.
The utility model frock clamp only needs a set of, just can realize 3-￠ 8
+ 0.016, 3-￠ 41.6
+ 0.027, 3-￠ 16.003
+ 0.016, 3-￠ 16.64
+ 0.019the processing in this 12 hole, and the utility model frock clamp is lighter than original fixture, and convenient mounting and clamping, only need to reverse handle and drive location-plate to position workpiece plane, does not need repeatedly to change the locating surface of fixture and workpiece.Horizontal processing becomes vertical processing, due to the change of center of gravity, has not only facilitated operator's installation, and improves the circularity in hole, the machining accuracy of perpendicularity to workpiece face.Take full advantage of the intellectuality of numerical control device machining center, high accuracy, changes cutter advantage easily, with part one side location, realize the processing in 12 holes repeatedly not moving, clamping parts in the situation that, the production cycle shortens greatly, has reached upgrading synergy, has reduced the object of labour intensity.Improve the integrated artistic level of this product, and accumulated for the technological process of production optimization of like product from now on provides technology.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
The utility model body 8 bottoms are provided with locating slot, two side symmetry has bolt holddown groove, thereby be convenient to bolt by reaching stationary fixture, body 8 is provided with the chip removal through hole corresponding with workpiece working position, on body sidewall, be connected and installed with " protruding " shape bearing 7 by screw 6, on bearing 7, have the cell body that can make location-plate 5 move, location-plate 5 is shaped as inverse-T-shaped, the straight bar part of location-plate 5 is placed in cell body, on the upper surface of bearing 7, have screwed hole, location-plate 5 is provided with horizontal draw-in groove, boss is established at handle 4 bar middle parts, lower end is provided with screw thread, the end of thread of handle 4 is placed in screwed hole, boss on handle 4 bars is placed in the horizontal draw-in groove of location-plate 5, pressing plate 3 is installed on bearing 7, pressing plate 3 is fixing with bearing 7 by pin 1 and screw 2.
