Abstract
The invention discloses a clamping device for processing a slender axle top hole. The device comprises a spindle and a chuck which are mounted on a body, wherein the spindle is provided with a central hole; a workpiece passes through the central hole of the spindle; a centering sleeve is sleeved at the tail end of the workpiece; the centering sleeve is a cylinder; one side of the outer wall of the cylinder is conical; the conical side of the outer wall of the centering sleeve is in contact with the inner wall of the spindle; the front end of the workpiece is clamped by the chuck; and the section of the workpiece extending out of the spindle is provided with a bracket fixed on a machine tool. The clamping device disclosed by the invention has a simple structure; and the centering sleeve is mounted between the tail end of the processed workpiece and the central hole of the spindle, and a central frame is mounted on the workpiece on the extending section of the spindle, thus the processing accuracy of the central holes at the two ends of the workpiece is sufficiently improved.
Description
Technical field:
The present invention relates to the Vehicle Processing field, relate in particular to a kind of clamping device of slender axles center hole processing.
Background technology:
Anchor clamps are to be used for fixing processing object in the machine-building process, make it to occupy correct position, with the device of accepting construction or detecting.Claim jig again.In a broad sense, any operation in technical process is used for installing rapidly, easily and safely the device of workpiece, all can be described as anchor clamps.For example weld jig, inspection jig, assembling jig, jig etc.
For draw ratio>processing of 35 slender axles two ends centre bore, all the time because on slender axles one end clamping and the chuck, owing to the length of slender axles; Place in the machine tool chief axis centre bore; When treating the main shaft high speed rotating, off-centre often appears in the two ends centre bore that processes, and machining accuracy is lower.
Summary of the invention:
To the prior art problem, the object of the invention provides a kind of clamping device of slender axles center hole processing, effectively raises slender axles good stability in the machine tooling process, and machining accuracy is high.
Technical scheme of the present invention is following:
The clamping device of slender axles center hole processing includes the main shaft, the chuck that are installed on the body, and main shaft is provided with centre bore; Workpiece passes spindle hole, it is characterized in that: workpiece end is set with the centering sleeve, and the centering sleeve is a cylindrical shell; Cylinder body outer wall one side is taper; Taper one side of centring sleeve drum outer wall contacts with the main shaft inwall, and described workpiece front end clamps through chuck, and workpiece stretches out the main shaft section support that is fixed on the lathe is installed.
The clamping device of described slender axles center hole processing, it is characterized in that: described support is a centre frame.
Advantage of the present invention is:
The present invention is simple in structure, between workpiece end of processing and spindle hole, the centering sleeve is installed, and is positioned at the main shaft section of stretching out on the workpiece centre frame is installed, and has fully improved the accuracy of workpiece two ends centre bore processing.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
The clamping device of slender axles center hole processing includes the main shaft 2, the chuck 3 that are installed on the body 1, and main shaft 2 is provided with centre bore 2-1; Workpiece passes main shaft 2 centre bore 2-1, and workpiece end is set with centering sleeve 4, and centering sleeve 4 is a cylindrical shell; Cylinder body outer wall one side is taper 4-1, and taper 4-1 one side of centering sleeve 4 outer walls contacts with main shaft 2 inwalls, and the workpiece front end clamps through chuck 3; Workpiece stretches out the main shaft section support 5 that is fixed on the body 1 is installed, and support 5 is a centre frame.
The present invention is applicable to draw ratio>35 slender axles, require two ends have A, B, C type centre bore or in the thin and long shafts of hexagonal hole.Should be before the processing according to cutting allowance alignment workpiece.Adopt the CA6150B big machine toolings of spindle through-hole such as (spindle through-hole reach 90mm).Processing method: 1) import part into main shaft, lean out 50-100mm, use centering sleeve 4 fixation workpieces, clamping work pieces at the other end.Planar end surface is made a call to a side centre bore.Note the speed that main shaft 2 rotating speeds and tailstock shake, avoid centre drill to fracture.2) go up follow-rest (servicing unit), unclamp claw after, pull out workpiece, adopt the mode on a folder one top, processing work cylindrical and axle head.3) measuring workpieces length turns around, last centre frame 5; The position of adopting earlier the mode on a folder one top to use the short adjustment of existing centre bore centre frame, after turn around, press from both sides centering end; Support with centre frame 5; When the cylindrical circular runout of no centre bore one end of dial gauge adjustment is in 0.05mm, lock centre frame, get centre bore.5) adopt a folder one top mode to accomplish whole processing.
Claims (2)
