Abstract
The utility model discloses a sliding block type clamp for grinding a large-sized thin-wall space ring type part. The sliding block type clamp comprises a clamp body (4), a movable type sliding block (3) and a sunk screw (2), wherein the clamp body is provided with a radial T-shaped through groove distributed in the circumferential direction; the movable type sliding block (3) is mounted in the T-shaped through groove; the movable type sliding blocks have different specifications for selection; the sizes of threaded holes of the movable type sliding blocks with different specifications are different; the sunk screw (2) is matched with the threaded hole of each of the movable type sliding blocks; when the clamp is mounted, the clamp body (4) is directly absorbed by the magnetic force of a circular flat-grinding machine tool working table-board; when clamping is performed by the clamp, the sunk screw (2) is connected with the clamp body (4), the movable type sliding block (3) and a part (1), the compaction of the part is realized through the screwing force of an thread, the upper surface of the clamp body (4) is a positioning surface, and a gap ranging from 0.05-0.1 mm is formed between the upper surface of the movable type sliding block (3) and the lower end face of the part (1). The sliding block type clamp has the following benefits: the structure is simple, the application is convenient and reliable, the applicability is high (one set of clamp can be used for processing various types of parts and is free of the influence of the self-deformation of the parts), the cost is low (the same clamp body is used for clamping different parts), and the efficiency is high (the same clamp can be used for clamping various types of parts, and the time for replacing a tool is saved).
Description
Technical field
This fixture is mounted on round plain grinding lathe, carries out the fixture of flat surface grinding for large thin-wall spacer ring class series parts.
Background technology
Large thin-wall spacer ring class part end face adopts mill processing method, because accessory size is compared with large (diameter phi 800～φ 1000mm), wall thickness little (2.375～4.625mm), precision high (wall thickness dimension tolerance only ± 0.025mm), parts fixation processing difficulties, distortion are large, precision is difficult for guaranteeing; Part forms series parts with the difference of diameter dimension, gauge, and single-piece is made frock clamp, drops into greatlyr, and the replacing installation holding time of fixture is long, and efficiency is low.
Summary of the invention
The object of the invention is to provide a kind of fixture, utilizes the adaptivity of fixture, realizes the processing of series parts, the clamping machining deformation of minimizing part, and a sleeve clamp can be realized the processing of various parts simultaneously, raises the efficiency.
The object of the invention is to realize by following technical scheme: a kind of slide block type fixture for the grinding of large thin-wall spacer ring class series parts, comprise chuck body 4, packaged type slide block 3, sunk screw 2, it is characterized in that: chuck body has the radially T-shaped groove of circumferential distribution, packaged type slide block 3 is installed in T-shaped groove, packaged type slide block has different specifications alternative, the screwed hole of the packaged type slide block of different size varies in size, and sunk screw 2 matches with the screwed hole of packaged type slide block; When fixture is installed, circle plain grinding lathe work top magnetic force directly holds chuck body 4, when fixture clamping, with sunk screw 2 jockey bodies 4, packaged type slide block 3 and part 1, realize the compression of part by the screwing force of screw thread, chuck body 4 upper surfaces are locating surface, and there is 0.05～0.1mm gap packaged type slide block 3 upper surfaces and part 1 lower surface.
The advantage of the invention is: have T-shaped groove chuck body (T-shaped groove quantity is determined by the uniform quantity of installing hole in spacer ring part) and coordinate from different packaged type slide blocks, by slide block in the movement of the T-shaped groove of chuck body and the use of different length sunk screw, the clamping processing while realizing the different spacer ring series parts cross grinding of diameter difference, thickness difference, hole reference circle size; In same packaged type slide block, there is the screwed hole (as M4, M6, M8) of multiple different sizes, can realize the clamping processing of multiple parts with different installing hole diameters; The uniform diverse location that is dispersed in circumference of clamping compacted position of part, makes clamping force and clamped position dispersion and uniform, prevents the clamping deformation of part; Large thin-wall spacer ring part, after operation processing in early stage, has distortion in various degree, and the fine setting of sunk screw and packaged type slide block rigging position in T-shaped groove, can solve the clamping problem of being out of shape part; Clamp structure is simple, easy to use and reliable, (sleeve clamp can be processed the part of multiple kinds to applicability by force, and be not subject to the impact of part self-deformation), cost low (using same chuck body when different parts fixation), efficiency high (same fixture can clamping various parts, save frock and change the time).

The specific embodiment:
In the present embodiment for the slide block type fixture of large thin-wall spacer ring class series parts grinding, comprise chuck body 4, packaged type slide block 3, sunk screw 2, it is characterized in that: chuck body has the radially T-shaped groove of circumferential distribution, packaged type slide block 3 is installed in T-shaped groove, packaged type slide block has different specifications alternative, the screwed hole of the packaged type slide block of different size varies in size, and sunk screw 2 matches with the screwed hole of packaged type slide block; When fixture is installed, circle plain grinding lathe work top magnetic force directly holds chuck body 4, when fixture clamping, with sunk screw 2 jockey bodies 4, packaged type slide block 3 and part 1, realize the compression of part by the screwing force of screw thread, chuck body 4 upper surfaces are locating surface, and there is 0.08mm gap packaged type slide block 3 upper surfaces and part 1 lower surface.
In the present embodiment, fixture use procedure is as follows:
1, the technological preparation before part grinding.
At the fabrication hole of the position of part end face installing hole processing belt countersunk head chamfering.The diameter of fabrication hole is slightly less than the diameter of installing hole, matches with standard sunk screw; Part both ends of the surface are every a hole processing countersunk head chamfering, and same hole only processes one end.The technological preparation of part as shown in Figure 2.
2, installing and using of fixture.
Circle plain grinding platen magnetic-adsorption chuck body bottom surface; Part lies in a horizontal plane in chuck body; According to fabrication hole choice criteria sunk screw and packaged type slide block; In T-shaped groove in chuck body, pack packaged type slide block into; With sunk screw connection sliding block and part; The radial position of fine setting slide block, after guaranteeing that sunk screw screws in, sunk screw sinks in the orifice chamfer of part and screw tapering face contacts completely with the fillet surface in hole; Tighten screw along cross symmetry direction.The clamping schematic diagram of fixture as shown in Figure 1.
3, the grinding of part
Press the technological preparation processing technology hole before part grinding; Press the installation and application clamping parts of fixture; Grinding part one end face; The part that unloads and overturn, and the installation and application of pressing fixture is with flour milling positioning and clamping part; Grinding other end.
