Below in conjunction with the accompanying drawings and specific embodiment is described in further details to the present invention：
The invention discloses a kind of slot grinding special fixture, the slot grinding fixture be particularly suitable for use in symmetrically arranged groove on part plus
Work.The fixture can ensure the relative positional accuracy of symmetrical channels, improve machining accuracy and crudy.The fixture is fixed to grinding machine
Upper use, here are specific embodiments：
The slot grinding special fixture of the present invention is mainly made up of five parts, respectively clamp body, master positioning and clamping part, angular fixed
Bit position, measuring basis part, above-mentioned five are partially assembled into and form whole fixture together.
The clamp body of the present invention includes base 1 and two supports, i.e. support 1 and support 23.Base 1 is generally grown
Cube shape, support 1 and support 23 are separately fixed at the both ends of base 1.Specifically as shown in Figure 1, Figure 2, Figure 3 shows.Clamp body is folder
The other parts of tool provide mount point, and remaining tetrameric parts is installed on clamp body.In specific implementation process,
Clamp body uses ironcasting, such as HT200.Not only cast using HT200, process and be relatively easy to, and due to HT200 itself
The characteristics of, so its deformation is also smaller after processing, can be very good to ensure the required precision of clamp body, so as to ensure whole fixture
Use and required precision.
The fixture of the present invention is typically required what is used on grinding machine.Accordingly, fixture base 1 lower surface
Two positioning keys 13 are set, and the two positioning keys 13 are fixedly connected using screw with base 1.Two positioning keys 13 are located at bottom respectively
The both ends of seat 1, it is specific as shown in Figure 2.The locating slot of two positioning keys 13 and the working face on grinding machine coordinates realization should during use
Positioning and connection between fixture and grinding machine are combined.The depth of parallelism≤0.02mm of the common axis of two positioning keys 13.
The master positioning of the present invention and clamping part are top including two, i.e. rolling center 4 and stationary center 5, two tops
Point is fitted on base 1 on two supports.In this embodiment, stationary center 5 is installed on support 1, by movable top
Point 4 is installed on support 23.Stationary center 5 is attached with support 1 by taper, can ensure connection it is firm simultaneously
Ensure the axiality of the fixture, preferential selection 1：20 taper.Rolling center 4 is arranged on support 23 along axis to enter
Row movement, workpiece is changed so as to realize that Workpiece clamping processing is unclamped with fixture.The afterbody of rolling center 4 by lock-screw 16 with
Guide shaft 9 connects, and the other end of guide shaft 9 passes support 23, and guide shaft 9 drives rolling center 4 to be moved along axis, and preferential is also leading
The end of axle 9 sets handle 12, and guide shaft 9 can realize quick-detachable connected mode with handle 12 by bearing pin.Specific knot
Structure is as shown in Figure 1 and Figure 2.The both ends of lock-screw 16 in the present invention are respectively provided with screw thread, be connected through a screw thread by rolling center 4 with
Connected between guide shaft 9.The material that stationary center and rolling center in the present invention use is T10, and passes through heat treatment

Between support 1 and support 23, survey mass 8 is correspondingly arranged at the opposite side of workpiece with angular position portion, and concrete structure is as schemed
1st, shown in Fig. 2.Survey mass 8 is fixedly attached on base 1 typically by bolt.The material selection of survey mass is 20# steel, is passed through
Carburizing, quenching are carried out to measuring surface, its end hardness is reached HRC53~58, ensures the requirement of its wearability.
The assembling of fixture and use process are as follows in the present invention：It is first that left side stationary center 5 is corresponding with support 1
Taper hole is installed；Then right side rolling center 4 and lock-screw 16, guide shaft 9, handle 12 are assembled, and locking is fixed
Position pin 11 is installed in place, and ensures axiality≤0.02mm of stationary center 5 and rolling center 4.Workpiece is installed, and adjusts guide shaft
9 with the distance of lock-screw 16, rolling center 4 is by workpiece pre-tightening and locked.The stub axle 7 angularly positioned is with being installed to positioning bottom
It is connected in the through hole of seat 6 and with spring 14.Stub axle 7 should be able to be slided freely up and down under spring force after assembling, without hindrance
Stagnant phenomenon, make stub axle 7 suitable to the angular positioning pretightning force of workpiece by adjusting screw plug 15, both accurate positionings are again convenient to pacify
Dress, dismounting.Survey mass 8 and base 1 are installed, ensure the measuring surface of survey mass 8 and the depth of parallelism of workpiece theoretical centerline
≤0.01mm.Installed finally by two positioning keys 13 of the bottom of base 1 with grinding machine, realize the coarse positioning of fixture, then use
The axis of dial gauge centering workpiece, realize that fixture and the final of grinding machine are accurately positioned.Pass through workpiece both ends first during grinding fluting
Centre bore carries out axial positioning with stationary center 5 and rolling center 4 and clamped, and is angularly positioned by stub axle 7；Then
Rotary handle 12, the auto lock of workpiece is realized, start grinding fluting.After the completion of grinding, measurement fluting size；Meet that processing will
Seek rear rotary handle 12, unclamp rolling center 4 and unload workpiece, u-turn grinding opposite side is slotted to size, ensures size and symmetrical
Degree requires.
The present invention fixture application after, not only processing efficiency than originally improves 2 times or so, its grinding after product once
Delivery-check qualified rate has reached more than 98%.The jig Design reaches in strict accordance with ergonomics and the requirement of human oriented design
Good man-machine harmony, facilitates the use of worker, reduces the labor intensity of worker.The fixture is applied to be positioned with both ends centre bore
Workpiece, when fluting size is inconsistent, only need to change measuring basis size, it is achieved thereby that sleeve clamp processing a variety of is opened
The effect of groove workpiece.
Angular position portion in the present invention can realize that workpiece is angular and be accurately positioned that master positioning and clamping part can
Realize the axially precisely positioned of workpiece and clamp, clamp body, master positioning and clamping part, angular position portion, measuring basis portion
Grade five part composition slot grinding special fixtures, between each several part mating reaction can realize the quick-clamping of workpiece is removed with
And be accurately positioned, ensure the crudy and processing efficiency of workpiece.
