The clamping block consists of a clamping body, wherein the clamping body is an inclined plane hexahedron; the middle part of an upper surface of the clamping body has a positioning hole which is vertical to the upper surface and is used for placing parts; a clamping groove is formed in the middle of an inclined plane along with a lowered side of the inclined plane and is integrally connected with the part positioning hole; a tool setting groove is formed in the middle of the other side of the inclined plane and is communicated with the positioning hole; and the bottom surface of the tool setting groove is parallel to a positioning surface and the bottom surface of a part chute. The part is placed in the positioning hole in the clamping block, the clamping block is placed in a jaw vice, the positioning bottom surface of the clamping block is leveled up through a standard block and is tightly clamped by the jaw vice, the tool setting groove is aligned, and then the part can be machined. By the clamping block, the problem of difficulty in positioning and clamping of the chute in the part machining process is solved, and the chute can be quickly clamped and positioned; a cutting tool can be quickly set; the part can be quickly machined; and the machining cost is reduced, and the machining efficiency and the yield of the part are improved.
Description
Technical field
The utility model belongs to the frock designing technique, relates to a kind of clamp that is used to process column part skewed slot.
Background technology
The column part that has skewed slot is a kind of part that is used for mechanical positioning or connection, in Aero-Space or other mechanical fields, is generally used.
See also Fig. 1, it is the structural representation that a kind of helicopter has the skewed slot part.This joint is by having a skewed slot in cylindrical part main body upper surface, laterally having a hole on the cylindrical part main body and form.At present, process such part and mainly contain three kinds of schemes: a kind of is to use built-up jig, and the part angle of bevel is balanced; Realization is to the processing of part skewed slot; The shortcoming of this kind scheme is that time is long, and each built-up jig scheme maybe be different, thereby has mismachining tolerance; A kind of is the milling machine head to be shown the angle consistent with skewed slot come processing parts, and the shortcoming of this kind scheme is that the pivot angle error is bigger, and it is overproof to occur part easily, is difficult to guarantee machining accuracy; A kind of is part to be placed on the five axis processing machine beds process, and the shortcoming of this kind scheme is that cost is too high.
Summary of the invention
The purpose of the utility model is: provide a kind of simple in structure, clamping is quick, can make things convenient for, accurately process the clamp of column part skewed slot.
The technical scheme of the utility model is: the clamp that is used to process column part skewed slot comprises a clamping body; Said clamping body bottom surface is a locating surface; Its upper surface is the inclined-plane, and the angle between the two is consistent with part skewed slot inclination angle, and the upper surface of said clamping body vertically is provided with the locating hole that is used to place part; The said clamping body side that raises along the inclined-plane has the tool setting groove; The tool setting groove communicates with locating hole, and the tool setting groove bottom is parallel with locating surface and part skewed slot bottom surface, reduces a side along the inclined-plane and has the clamping slot that is connected as a single entity with the part locating hole.
Said cutter groove and cylindrical part dovetail trench horizontalization are neat.
Locating hole can be square hole or circular hole.
Said clamping body is an inclined-plane hexahedron, and its lower surface is a locating surface, and upper surface is the inclined-plane.
The utility model has the advantages that: the utility model is used to process the clamp of column part skewed slot and has realized the quick-clamping location; Realized quick tool setting; Realized the rapid processing of part; Reduce processing cost, improved working (machining) efficiency and part qualification rate.Evidence, the working (machining) efficiency of the utility model have improved more than 2 times, the part qualification rate from original 80% to be issued to 100%.

The specific embodiment
Explain further details in the face of the utility model down.
Please be simultaneously referring to Fig. 2 and Fig. 3, wherein Fig. 2 is the structural representation that the utility model is used to process clamp first embodiment of column part skewed slot, Fig. 3 is the vertical view of Fig. 2.In this embodiment, said clamp is used for the skewed slot of processing column shape part.The clamp that the utility model is used to process column part skewed slot comprises a clamping body 1, and said clamping body 1 is an inclined-plane hexahedron, and its lower surface is a plane, is locating surface 5, and upper surface is the inclined-plane, and the angle between the upper and lower surfaces is consistent with the inclination angle of skewed slot.The upper surface middle part of said clamping body 1 has one to be used to place the locating hole 2 of cylindrical part perpendicular to upper surface, has clamping slot 3 in the middle of reducing a side along the inclined-plane, is connected as a single entity with part locating hole 2.Have tool setting groove 4 in the middle of the inclined-plane opposite side, tool setting groove 4 communicates with locating hole 2.Tool setting groove 4 bottom surfaces and locating surface 5, part skewed slot bottom surface are all parallel, and cutter groove 4 is neat with cylindrical part dovetail trench horizontalization.
See also Fig. 4, it is the processing sketch map of this embodiment.Actually add man-hour, cylindrical part is placed in the clamp 2 li of locating holes, make the cylindrical part end face parallel with the inclined-plane of clamping body.Then clamp is positioned in the vice, levels up bottom surface 5, clamp location with calibrated bolck, clamp with vice by diagram clamping force direction, centering tool setting groove 4 is processed cylindrical part along the cutter groove, can directly obtain the part skewed slot.
See also Fig. 5, it is the structural representation that the utility model is used to process clamp second embodiment of column part skewed slot.This embodiment is similar with first embodiment, and just processing object is the square body skewed slot, so the locating hole on the clamping body is the square hole that size and square main body section are complementary.Its process is similar with a last embodiment, behind the good square body of positioning and fixing, directly along the feed of cutter groove, processes skewed slot.
In addition; The utility model is used to process the clamp of column part skewed slot can also do further improvement; Particularly its fixed form can be done certain variation; Be cylinder be placed on step up in the body locating hole after, be not limited to clamp with vice, cylinder can be fixedly clamped with the mode of pressing plate or locked with bolts.
The clamp that the utility model is used to process column part skewed slot through design one have a cutter groove oblique parallelepiped; The cylinder part is placed in this oblique parallelepiped's locating hole, after the positioning and fixing, can directly processes the skewed slot of necessary requirement along the cutter groove; Therefore easy to process; And utilizing vice just can be fixedly clamped, clamping is quick, can realize big in batches production.In addition,, therefore can guarantee machining accuracy and homogeneity of product, effectively guarantee crudy to have improved yield rate because the inclined-plane slope of oblique parallelepiped and cutter groove can require accurately to make according to the part skewed slot in advance.
