Abstract

The utility model relates to a hydrostatic lathe turning tool post mechanism, which mainly solves the problems of the low precision, small tool clamping area, easy crawling of a lead rail and easy abrasion of the existing lathe turning tool post. The static press lathe turning tool post mechanism is characterized in that, the inside of a groove on the upper part of an upper tool post (7) is provided with an upper pressure plate (2); the cam position of the upper pressure plate (2) is provided with a clamping body (8) with an inclined plane on the lower part matched with a cutting board (6); an axis (4) runs through the upper pressure plate and the clamping body (2, 8); the left end of the axis (4) is connected with an oil cylinder (2); and an X axis lead rail (12) and a Z axis lead rail (18) are both hydrostatic lead rails. The hydrostatic lathe turning tool post mechanism is characterized by high processing precision of work pieces, large tool clamping area, no crawling, stable transmission and long service life.

Description

Static pressure turning head mechanism

Technical field:

The utility model belongs to machinery manufacturing technology field, relates in particular to a kind of static pressure turning head mechanism.

Background technology:

At present, traditional mode is the multilayer knife rest on the lathe market, big cargo chute, and middle slide carriage and small tool and square cutter holder, because the number of plies is many, complex structure, middle tone domain joint is many, so precision and poor rigidity, and the long-pending processing back workpiece accuracy that causes for a short time of folder knife face is not high.Simultaneously, the direction that can only not have existing hydrostatic slideway moves (promptly along being parallel to the guide rail direction, X-axis), and along using common rail plate perpendicular to guide rail direction (Z axle), rail plate exist oil site few, easily creep, easy to wear, the easy defective of forging a knife, make the lathe overall precision reduce the lost of life.

The utility model content:

Existing turning head precision is low in order to overcome, the folder knife face long-pending little, guide rail is easily creeped, deficiency easy to wear, the utility model provides a kind of static pressure turning head mechanism, this static pressure turning head mechanism have workpiece machining accuracy height, folder knife face long-pending greatly, do not creep, stable drive, long characteristics of life-span.

The technical solution of the utility model is: a kind of static pressure turning head mechanism, comprise upper tool post, carriage, left and right knife plate, X-axis, Z axis rail, in the groove on upper tool post top top board is arranged, the boss place of top board is equipped with the clamping body that lower bevel cooperates with knife plate, and pass axle between top board, the clamping body, the left end of axle connects oil cylinder, and X-axis, Z axis rail are hydrostatic slideway.

The utlity model has following beneficial effect: owing to take such scheme, this turning head mechanism is made up of carriage and upper tool post and left and right knife plate, changed multilayer cutter frame structure in the past, made that error is little, precision is high, left and right knife plate moves on upper tool post, can adapt to the bigger workpiece of vary in diameter scope, good rigidly, the folder knife face is long-pending big, can effectively increase cutting force and reduce vibrations, be applicable to the brute force cutting that overhangs greatly, thereby improved the machining accuracy of workpiece.X-axis, Z axis rail all adopt constant current closed hydrostatic slideway pair, make to be in the neat liquid abrasion state between the guide pass all the time, have guaranteed that low speed is not creeped, the floating liters per hour of static pressure reports to the police, and make that equipment is safer, transmission is more steady, the life-span is high, precision is high.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model intermediate slide;

Accompanying drawing 2 is schematic diagrames of hydrostatic slideway in the utility model.

1-oil cylinder among the figure, 2-top board, 3-travel switch, 4-axle, 5-clamping body, 6-knife plate, 7-upper tool post, 8-Z axis rail, 9-carriage, 10-carriage motor, 11-upper tool post motor, 12-X axis rail.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By shown in Figure 1, a kind of static pressure turning head mechanism comprises knife rest (7,9), knife plate 6, X-axis, Z axis rail (12,8), knife plate 6 are divided into left and right two, carriage 9 can move along X-axis guide rail 12, driven by carriage motor 10, upper tool post 7 can move along Z axis rail 8, is driven by upper tool post motor 11, two motors are AC servo motor, high efficiency.In the groove on upper tool post 7 tops top board 2 is arranged, the boss place of top board 2 is equipped with the clamping body 8 that lower bevel cooperates with knife plate 6, and the two is (2 years old, 8) pass axle 4 between, the left end of axle 4 connects oil cylinder 2, oil cylinder 2 is built-in with disk spring, on the right side of upper tool post 7 travel switch 3 is arranged, and travel switch 3 aligns with axle 4.X-axis, Z axis rail (12,8) be hydrostatic slideway, adopt the hydrostatic slideway pair of the single pump control in constant current closed type static pressure list chamber, make and be in the neat liquid abrasion state between the guide pass all the time, guaranteed that low speed do not creep, the floating liters per hour of static pressure is reported to the police, and make equipment safer, thereby transmission is more steady, the life-span is high, the high raising of precision competition capability.

In this cutter frame mechanism, utilize left and right knife plate 6 motor-driven the moving on upper tool post 7 on the upper tool post 7, can adapt to the bigger workpiece of vary in diameter scope, good rigidly, the folder knife face long-pending from, can effectively increase cutting force and reduce vibrations, be applicable to the brute force cutting that overhangs greatly, thereby improve the machining accuracy of workpiece.

When knife plate 6 needs are mobile, control oil cylinder 1, the disk spring in the pressure oil compression cylinder, loosen clamping body 5, thereby knife plate 6 is loosened, and at this moment knife plate 6 is promptly removable, after knife plate 6 moves into place, travel switch 3 sends signal, cut off the pressure oil of oil cylinder 1, make in the oil cylinder disk spring clamping that resets, promptly finish the automatic clamping of knife plate 6 and the process of loosening, simple to operation, reliable clamping.

Claims

1, a kind of static pressure turning head mechanism, comprise knife rest (7,9), knife plate (6), X-axis, Z axis rail (12,8), it is characterized in that: in the groove on upper tool post (7) top top board (2) is arranged, the boss place of top board (2) is equipped with the clamping body (8) that lower bevel cooperates with knife plate (6), and the two (2,8) pass axle (4) between, the left end of axle (4) connects oil cylinder (2), and X-axis, Z axis rail (12,8) are hydrostatic slideway.
