Abstract

The utility model relates to a fine adjusting cutter box used for cutter installation on a lathe. The cutter fine adjusting cutter box comprises a cutter box, a sloping block, a screw, a cutter, a lock nut and an adjusting screw, wherein, the cutter box is fixed on a square tool post of the lathe through a bolt; an oblique cone contact is adopted between the cutter box and the sloping block; a top plug is arranged at one end of the sloping block; when the cutter is loaded in the cutter box, the contact surface of the sloping block and the cutter is parallel to the wall surface of the bottom part of the cutter box; the sloping block is lifted and moved by turning the adjusting screw, so that a tool point of the cutter is adjusted to a position as high as the center of a main shaft, and the purpose of fine adjustment of the cutter up and down is achieved, the screw is used for compressing the cutter; and the lock nut is used for locking the adjusting screw and preventing the adjusting screw to loose. The utility model has the advantages that the structure is simple, the operation and the adjustment are convenient, the time for adjusting the cutter is shortened, the work efficiency is improved, and the cost is saved.

Description

Cutter fine setting cutter box

Technical field

The utility model is designed for the fine setting cutter box that lathe is fixed a cutting tool and installed and used.

Background technology

At present the cutter box that uses is for can not mode or be placed on the mode that directly compresses on the knife rest behind cutter underlay pad, there is following defective in this structure: one, because the alignment of shafts height of every lathe there are differences, each cutter is also inequality simultaneously, and the tool dimension after the reconditioning changes, and when reinstalling the cutter box, the point of a knife installation site of its cutter is on the alignment of shafts is not contour, all need to adjust, the cutter adjustment is just inconvenient; And position of tool tip is inaccurate to alignment of shafts height, will cause between cutter and the workpiece to produce the big and quick abrasion of frictional resistance, and the cutter that need more renew, the roughness and the accuracy of form and position of product are relatively poor, produce waste thus; Its two, the point of a knife of cutter adopts pad multi-layer gasket mode adjustment upper-lower position, the stability of cutter clamping and poor reliability.Above-mentioned reason will cause the use durability of cutter to reduce, and the crudy of product descends, and causing producing the cost that uses cutter increases.

Summary of the invention

The purpose of the utility model design provides a kind of fine setting cutter box that can adjust the cutter upper-lower position.

The technical scheme that realizes the utility model above-mentioned purpose is:

Cutter fine setting cutter box is made up of cutter box, skewback, screw, cutter, locking nut and adjustment screw, this cutter box is fixed on the square tool post of lathe by screw, described cutter box adopts scalene cone to contact with skewback, skewback one end is provided with the top and fastens, skewback and cutter contact-making surface were parallel to cutter box bottom wall when cutter was packed the cutter box into, adjust screw by rotation, promote skewback lifting displacement, thereby the point of a knife that makes cutter transfers to and alignment of shafts equal-height position, reach cutter inching purpose up and down, screw is used to compress cutter, and locking nut is used for locking adjustment screw to be prevented to become flexible.

The inclined-plane of described cutter box is identical with the gradient that the inclined-plane of skewback adopts, and its direction is opposite.

The invention has the beneficial effects as follows: come mobile skewback by the extruding of adjusting screw, the position of adjusting cutter is moved in the skewback position, the point of a knife that improves trimming tool bit is to the accuracy contour with the alignment of shafts, thereby guaranteed that cutter is in the optimized cutting state, improved the durability of cutter, the utility model is simple in structure, operation is easy to adjust, shortens the time of adjusting cutter, increase work efficiency, save cost.

Description of drawings

Fig. 1 is the structure diagram of fine setting cutter box;

Fig. 2 is A---the A cut-away view of fine setting cutter box;

Among the figure: 1, cutter box; 2, skewback; 3, screw; 4, cutter; 5, adjust screw; 6, locking nut; 7, fasten on the top.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.

Cutter box with regulatable is fixed on the square tool post of lathe earlier, then the welding alloy cutter 4 of specification 14 * 14 or 18 * 18 is packed into as Fig. 1 and finely tune in the cutter box, screw 6 is adjusted in rotation, promoting top on the skewback 2 fastens 7 and makes and move on the skewback 2, make the point of a knife of cutter 4 transfer to place with the contour H of the alignment of shafts, rotary screw 3 compresses cutter 4, the test run part processing, as on part end face, there being the cylinder small boss to produce, the point of a knife that then is cutter 4 is low, should unclamp screw 3, rotation adjustment screw 6, promote to move on the skewback 2, heighten the height of point of a knife; When on part end face, producing the small boss of circular cone, then heightened for the point of a knife of cutter 4, also should unclamp screw 3, rotation adjustment screw 6, promotion skewback 2 is moved down, turn down the height of point of a knife, after the processing of car part examination several times, when on part end face, both not had boss and producing, at this moment the height of cutter mixes up substantially, adjust screw 6 with nut 5 lockings at last and prevent to become flexible, adjust screw 6 fix tightly cutters, finish installation, the adjustment process of cutter.When re-using behind the cutter grinding, repeat above-mentioned cutter adjustment process.

Claims

1, cutter fine setting cutter box is by the cutter box, skewback, screw, cutter, locking nut and adjustment screw are formed, this cutter box is fixed on the square tool post of lathe by screw, it is characterized in that described cutter box and skewback adopt scalene cone to contact, skewback one end is provided with the top and fastens, skewback and cutter contact-making surface were parallel to cutter box bottom wall when cutter was packed the cutter box into, adjust screw by rotation, promote skewback lifting displacement, thereby the point of a knife that makes cutter transfers to and alignment of shafts equal-height position, reach cutter inching purpose up and down, screw is used to compress cutter, and locking nut is used for locking adjustment screw to be prevented to become flexible.

2, cutter fine setting cutter box according to claim 1, it is characterized in that: the inclined-plane of described cutter box is identical with the gradient that the inclined-plane of skewback adopts, and its direction is opposite.
