Abstract

The utility model discloses an adapter clamper, comprising a center rack on a machine bed table and connected with the machine bed table by a slide rail device, a square hole round plate mounted in the axle center of the center rack, wherein the square hole round plate and the center rack are positioned and fixed by a hammer; the square hole round plate is coaxial with the positioning axle in a main axle hole of a power box; positioning pads are arranged at the four corners of the square hole round plate and a safe connection plate is sleeved with the positioning axle; the safe connection plate and a machine bed chuck are connected and fixed by a SPL locking bolt; the center rack uses an upper open cover way, a large opening and a cross key positioning structure. The square type of the large cube workpiece mounting way is changed into the gyration circle type, so as to satisfy the requirement of the large digital control horizontal lathes for the gyration of the large cube workpiece with features of large outward extension, heavy weight and large appearance size.

Description

A kind of side changes the circle anchor clamps

Technical field

The utility model belongs to technical field of mechanical manufacturing equipment, and relating to a kind of side changes the circle anchor clamps.

Background technology

Fluid cylinder is one of critical component of slush pump, fluid cylinder belongs to the cube part, and its appearance and size is bigger, and weight is heavier, its inner chamber has deep hole, taper hole, major diameter screw thread, various circular arcs etc., complex structure, manufacturing procedure is many and to the requirement height of process equipment, simultaneously because this heavy parts belongs to production in enormous quantities, the station conversion is many, equipment needed thereby is many, and the operation volume of the circular flow is big, and processing cost can't effectively be reduced.

Summary of the invention

The purpose of this utility model provides a kind of side changes the circle anchor clamps, has solved the requirement height that exists in the prior art process equipment, and the station conversion is many, and equipment needed thereby is many, the problem that the operation volume of the circular flow is big.

The technical scheme that the utility model adopted is, a kind of side changes the circle anchor clamps, comprise the centre frame that is provided with on the lathe table top, be connected by railroad between centre frame and the lathe table top, the axle center of centre frame is equipped with the square hole plectane, positions and fixes by the top tool between square hole plectane and the centre frame, and the locating shaft of installing in the spindle hole of square hole plectane and headstock is coaxially set, the place, four right angles of square hole plectane is provided with locating pad, is set with safe connecting plate on the locating shaft.

Side of the present utility model changes the circle anchor clamps, and its feature also is:

The machine chuck of described safe connecting plate and headstock termination is connected and fixed by the SPL check bolt.

Uncap on described centre frame adopts form, big opening and the cross key location structure that intersects.

The beneficial effects of the utility model are, compact conformation, safe and reliable, easy to use has been realized the transformation of two kinds of processing modes, the one, and the processing of fluid cylinder slotted hole can change the horizontal digital-control lathe into by vertical numerical controlled lathe and process; The 2nd, the processing of screw thread can be processed by the mode that thread milling changes cutting thread into, has at utmost realized the operation merging, has guaranteed the product form and position tolerance, has improved surface quality and working (machining) efficiency.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, the structure that the utility model side changes the circle anchor clamps is, comprise the centre frame 8 that is provided with on the lathe table top 11, be connected by railroad 7 between centre frame 8 and the lathe table top 11, the axle center of centre frame 8 is equipped with square hole plectane 6, position and fix by three top tools 10 between square hole plectane 6 and the centre frame 8, the locating shaft of installing in the spindle hole 2 of square hole plectane 6 and headstock 15 is coaxially set, the place, four right angles of square hole plectane 6 is provided with locating pad 9, be set with safe connecting plate 4 on the locating shaft 5, safe connecting plate 4 is connected and fixed by the SPL bolt with the machine chuck 3 of headstock 1 termination.

Pass rectangle parts to be processed in the square hole plectane 6, can realize of the conversion of the rectangular profile of parts to be processed to turning circle; Adopt the vertical bilateral location of 90 degree on the square hole plectane, guaranteed the relative tram of workpiece foreign side with square hole plectane cylindrical.

Centre frame 8 adopts Welding Structure to reduce weight, adopts hot destressing mode to guarantee the stability of centre frame, and the form of uncapping on centre frame adopts and big opening form have made things convenient for the installation of large-scale workpiece and square hole plectane; Centre frame adopt to intersect the cross key locate mode, has guaranteed the parallel of last retracting cylinder roller and two following retracting cylinder roller axis.

Two locating shafts of whole machine adopted cooperate with workpiece two ends locating hole respectively, and two locating shaft centre bores are top to the top with the lathe two ends respectively, realize the adjustment of workpiece centering location and centre frame fast; Workpiece is rigidly connected by safety connecting plate and locating shaft transition realization and machine chuck, the workpiece axial displacement trend of effectively having avoided resistance to cutting to cause; Parts such as workpiece, positioning disk, square hole plectane all adopt low level to install, and need not to adjust in a high position, have improved security greatly; All connections, fastening place bolt all adopt the SPL check bolt, guaranteed clamping, have connected effectively reliably.

The utility model side changes the circle anchor clamps and designs by transformational structure, realized that large-scale cube clamping workpiece mode is by square transformation to the turning circle form, satisfied in of the revolution requirement of large-sized numerical control horizontal lathe overhanging big, weight is big, appearance and size is big cube workpiece, finish the processing of the conical surface, major diameter screw thread, slotted hole, curved surface cavity etc., and by optimization to structure, make the type clamping workpiece centering simply quick, increase the measure of secure context simultaneously, make manufacture process meet the HSE requirement more.
