Description

Double-cutter clamp of numerical control lathe

Technical Field

The utility model relates to a two cutter anchor clamps of numerical control lathe belongs to lathe frock clamp technical field.

Background

The current manufacturing of boring cutters of numerically controlled lathes is standardized and serialized, and the boring cutters are tools for cutting machining in mechanical manufacturing. The boring process is a more difficult process than other machining processes. With the popularization of common numerically controlled lathes, in hole boring, a boring cutter is fussy and inconvenient to mount in a square cutter frame, so that a simpler, more convenient and more precise cutter mounting method is needed to ensure the quality of products. In addition, in the existing machining, only one type of cutter, such as a boring cutter and a drill bit, can be clamped at a time, and machining efficiency is reduced invisibly.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the utility model provides a two cutter anchor clamps of numerical control lathe to solve the inconvenient operation that current frock clamp exists, work efficiency is low, and can not install boring cutter and drill bit scheduling problem simultaneously.

The technical scheme of the utility model is that: a numerically controlled lathe dual tool holder comprising: the clamp comprises a clamp body, spring jackets and locking nuts, wherein the clamp body comprises a U-shaped seat and locking cylinders respectively arranged at two ends of the U-shaped seat, each locking cylinder is provided with the locking nut and the spring jacket in a matched mode, the spring jackets are clamped between the locking cylinders and the locking nuts, the spring jackets are used for clamping cutters, and a stop block is arranged at one end, close to the back of the U-shaped seat, of the back face of the U-shaped seat.

The two ends of the U-shaped seat are provided with through holes communicated with the locking barrel, and the through holes at the two ends of the U-shaped seat are suitable for placing a cutter handle extending backwards from the inside of the spring clamp sleeve.

The U-shaped seat is a square block.

The locking nut is a hexagonal nut.

The utility model has the advantages that: the utility model discloses forming spring clamp cover, U type seat, lock nut and a locking section of thick bamboo combination and installing the anchor clamps of boring cutter and drill bit simultaneously, add man-hour can install two cutters respectively in two spring clamp covers, install the cutter handle in U type seat and fixed back, put anchor clamps whole on the cubic knife rest again, make U type seat and stop block fixed by cubic knife rest centre gripping can. Compared with the existing clamping mode, the clamp has the advantages of convenience in operation, high working efficiency, strong practicability and the like, and particularly, the boring cutter and the drill bit can be installed simultaneously, so that the cutter changing time between machining procedures is greatly shortened, and the machining efficiency is improved.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

referring to fig. 1 to 4, a dual tool holder for a numerically controlled lathe according to the present invention includes: the anchor clamps body, spring holder 2, and lock nut 1, the anchor clamps body includes U type seat 4, and set up the locking section of thick bamboo 3 on 4 both ends heads of U type seat respectively, every locking section of thick bamboo 3 is supporting to be provided with lock nut 1 and spring holder cover 2, be equipped with the bell mouth that matches with 2 appearances of spring holder cover in the locking section of

thick bamboo

3, 3 upper portion outsides of locking section of thick bamboo are equipped with the external screw thread supporting with lock nut 1, during the installation, spring holder cover 2 is held between locking section of thick bamboo 3 and lock nut 1 by the centre gripping, and the processing cutter is by the centre gripping in spring holder cover 2, when screwing up lock nut 1, thereby spring holder cover 2 draws in gradually and presss from both sides tight processing.

Through holes communicated with the locking barrel 3 are formed in two ends of the U-shaped seat 4, and the through holes in the two ends of the U-shaped seat 4 are suitable for placing a tool handle extending backwards from the inside of the spring jacket 2, so that the normal installation of a machining tool is realized. The spacing distance between the two ends of the U-shaped seat 4 can be determined according to the actual processing requirement, and the normal processing of parts is preferably not influenced.

The U-shaped seat 4 is a square block so as to be convenient for clamping and fixing. Preferably, a stop block 5 is arranged at one end of the back surface of the U-shaped seat 4, when the clamp body is clamped by the square tool rest, the U-shaped seat 4 is fixed by a bolt at one side, and the stop block 5 is fixed by a bolt at the adjacent side, so that the fixing effect can be improved.

When in processing, a processing tool is clamped in the spring jacket 2, then the locking nut 1 is screwed down to gradually draw the spring jacket 2 so as to clamp the processing tool, and then the U-shaped seat 4 and the stop block 5 are clamped and fixed on the square tool rest.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
