Description
Technical field
The present invention relates to a kind of rotary lathe and use anchor clamps.
Background technology
In general production and processing, process the coaxial not isometrical hole of a plurality of stageds now mainly with machining center and these two kinds of processing mode processing of boring.Boring processing speed is slow, efficient is low, and the Cutter Body Processing with Machining Center cost is higher, influences economic benefit; Most of for this reason processing is all changed in the turning processing.Because the clamping mode (three-jaw, four paws) of lathe can not satisfy the clamping of the irregular workpiece of profile, usually can use frock clamp.Existing frock clamp is guaranteeing under the prerequisite that processing can be carried out smoothly, mainly with repeated removal clamping and frock axial displacement dual mode clamping workpiece.Repeated removal clamping advantage is that the coaxial not isometrical hole dimension precision of each staged of processing is high, and weak point is that the repeated removal clamping makes positioning reference, precision inconsistent, and dimensional accuracy is low between the Kong Yukong, self size disparity is big, causes the whole workpiece quality to descend; The advantage of frock axial displacement is a clamping; Positioning reference, precision unanimity, shortcoming is that workpiece centre-of gravity shift main shaft gyration centre distance is far away after the displacement, prevents that centrifugal force is excessive in the process; Need to reduce the lathe rotating speed; Influence machined surface roughness, also reduced operating efficiency, make troubles for automated production in enormous quantities.
Summary of the invention
The purpose of this invention is to provide a kind of positioning reference, precision unanimity, the rotary lathe that can promote the whole workpiece dimensional accuracy is used anchor clamps.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of rotary lathe is used anchor clamps; Comprise telophragma (1), terminal pad (2), flap (3), pressing plate one (4), block one (5), location-plate one (6), location-plate two (7), connecting axle (8), locating piece (9), pressing plate two (10), block two (11) and motherboard (12); Said telophragma (1) is fixedly connected with terminal pad (2); Terminal pad (2) is fixed on the lathe spindle; Flap (3) is arranged on the indentation, there of motherboard (12) and is connected on the telophragma (1); The big end of connecting axle (8) is arranged in the telophragma hole, and small end is connected with flap, and motherboard (12) oppositely is fastened on the telophragma (1); Block one (5), location-plate one (6), location-plate two (7), locating piece (9) and pressing plate two (10) are fixed on the flap (3), and block one (5) and pressing plate two (10) are fixed on the motherboard (12).
Said telophragma (1) is fixed on the terminal pad (2) through 4 interior hexagonal cylindrical bolts.
Said flap (3) passes flap (3) arc groove through 2 interior hexagonal cylindrical bolts and is connected on the telophragma (1).
Said motherboard (12) oppositely is fastened on the telophragma (1) through 4 interior hexagonal cylindrical bolts.
A kind of rotary lathe of the present invention is used anchor clamps, is the special fixture of the workpiece that dimensional accuracy is high between a plurality of eccentric orfices of machined into and the Kong Yukong, with the chuck apparatus of manual mode control; Compact conformation, simple; Mounting or dismounting are convenient, guarantee that a clamping just can satisfy to process the high workpiece of dimensional accuracy between two eccentric orfices and the Kong Yukong, and positioning reference, precision unanimity; Eliminate the centrifugal forces affect that the processing eccentric orfice causes; Promote the whole workpiece dimensional accuracy, increase work efficiency, the convenient batch process in batches.

Among the figure: 1, telophragma; 2, terminal pad; 3, flap; 4, pressing plate one; 5, block one; 6, location-plate one; 7, location-plate two; 8, connecting axle; 9, locating piece; 10, pressing plate two; 11, block two; 12, motherboard.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, rotary lathe is used anchor clamps, comprises telophragma 1, terminal pad 2, flap 3, pressing plate 1, block 1, location-plate 1, location-plate 27, connecting axle 8, locating piece 9, pressing plate 2 10, block 2 11 and motherboard 12; Telophragma 1 is fixedly connected with terminal pad 2, and terminal pad 2 is fixed on the lathe spindle, and flap 3 is arranged on the indentation, there of motherboard 12 and is connected on the telophragma 1; The big end of connecting axle 8 is arranged in the telophragma hole, and small end is connected with flap, and motherboard 12 oppositely is fastened on the telophragma 1; Block 1, location-plate 1, location-plate 27, locating piece 9 and pressing plate 2 10 are fixed on the flap 3, and block 1 is fixed on the motherboard 12 with pressing plate 2 10, this rotary lathe with anchor clamps at first the interior hexagonal cylindrical bolt through 4 be fixed on terminal pad 2 on the lathe spindle; That the terminal pad material adopts is casting pig (HT300), in " vexed car " accident that the assurance lathe possibly occur in running, preferentially damages terminal pad; Other main parts size of protection lathe; Telophragma 1 is to be fixed together through 4 interior hexagonal cylindrical bolts and terminal pad 2, and 4 interior hexagonal cylindrical bolts of motherboard 12 usefulness oppositely are fastened on the telophragma 1, guarantees and is connected; 2, telophragma 1 rotates with machine tool chief axis together; Connecting axle 8 big ends are placed in the telophragma hole through the size cooperation, and small end cooperates with flap, confirms flap 3 pivots; Flap 3 is placed on the indentation, there of motherboard 12; Pass the flap arc groove with 2 interior hexagonal cylindrical bolts and be connected on the telophragma 1, location-plate, block, pressing plate are fixed on motherboard and the flap with interior hexagonal cylindrical bolt respectively, overlap frock clamp to this when lathe is removed at needs; Removed motherboard; Can dismantle telophragma, do as a whole through 4 bolts that are connected with main shaft on the directly loosening terminal pad of 4 through holes on the telophragma, the minimizing amount of labour and clamping time with terminal pad.
Add man-hour, at first lie in the bottom surface of workpiece on the flap 3, two limits lean against respectively on location-plate 1, the location-plate 27; Confirmed the positioning reference of workpiece, locking pressure plate 1, pressing plate 2 10, clamping work pieces; Dextrorotation walks around 3, lets locating piece 9 lean against (bolt is compensation cast blank size difference, microcall) on the bolt of block 2 11 earlier; Hole one makes the axle center overlap with spindle axis through rotation; Two bolts in locking flap arc groove place guarantee to add man-hour and main shaft does not have relative displacement, machining hole one; After the completion, two bolts in loosening flap arc groove place rotate counterclockwise again, lean against on the bolt of block 1; Two axle center, hole are overlapped with spindle axis, locking, machining hole two is through calculating; Process two holes at flap 3 center rotational workpieces, can guarantee that workpiece centre-of gravity shift main shaft gyration center amount is minimum, and machining hole one, two o'clock; Block 1, block 2 11 also play the effect of counterweigh, guarantee that it is minimum that centrifugal force is dropped in the process; Thereby improve the lathe rotating speed, also improved the roughness of finished surface, also improve the dimensional accuracy between two holes through adjustment block one, block two.
