Abstract

The utility model relates to a tool rest, which comprises a tool apron. A moving block guide groove or a guide hole with the guiding direction extending along a straight line is disposed on the tool apron, and the guiding direction of the moving block guide groove or the guide hole is defined as the forward and backward direction. A moving block moving forward and backward is assembled in the moving block guide groove or the guide hole in guiding mode, and a compression screw used for locking or releasing the moving block penetrates through the groove wall of the moving block guide groove or the hole wall of the guide hole. A tool groove used for assembling a tool in movably-guiding mode is disposed at the front end of the moving block, the guiding direction of the tool groove is the forward and backward direction, a screwed hole extending forward and communicated with the tool groove is disposed at the rear end of the moving block, and an adjusting screw used for being directly or indirectly matched with the rear end of the corresponding tool in upward-pushing mode is arranged in the screwed hole in screwing mode. The tool rest resolves the problem that the tool of an existing machine-tool tool rest has poor accuracy in adjusting.

Description

Knife rest

Technical field

The utility model relates to the knife rest that is used for fixing cutter on a kind of lathe.

Background technology

At present, the knife rest on the engine lathe is a squaring head, and this knife rest adopts screw fixed cutting tool; When regulating the tool position, earlier the screw on the tool rest of knife rest is unscrewed, but after unscrewing, need to guarantee that screw still has pressure to cutter; Otherwise cutter can become flexible the skew original position, knocks cutter then and makes cutter move the purpose that reaches adjusting forward or backwards, in the process of knocking; Percussion power too conference makes tool displacement too big, otherwise the displacement of cutter is too little, makes percussion power lean on operator's experience decision; Test run is with often regulate will be repeatedly several times, but the phenomenon of dimension overproof is arranged also the time, so the cutter of squaring head is regulated poor accuracy, efficient is low.

The utility model content

The utility model provides a kind of knife rest, is intended to solve the problem that the cutter of existing machine tool knife rest is regulated poor accuracy.

In order to address the above problem, the technical scheme of the utility model is following:

A kind of knife rest; Comprise tool rest; Said tool rest is provided with guide direction along linearly extended movable block guide groove or pilot hole; The guide direction of movable block guide groove or pilot hole is defined as fore-and-aft direction, and guiding is equipped with the movable block that moves forward and backward in said movable block guide groove or the pilot hole, is equipped with the housing screw that is used to lock or discharge movable block on the cell wall of said movable block guide groove or the hole wall of pilot hole; Said movable block front end offers the cutter groove that is used for activity-oriented assembling cutter; The guide direction of cutter groove is a fore-and-aft direction, and the movable block rear end offers the screwed hole that is communicated with said cutter groove that extends forward, is installed with in the screwed hole to be used for the direct or indirect adjustment screw that cooperates with rear end corresponding cutter pushing tow.

Be provided with the unthreaded hole that is communicated between screwed hole and the cutter groove in the said movable block, be equipped with the fine setting fore-set that is used for the jacking force of adjustment screw is passed to corresponding cutters in the unthreaded hole.

The movable block activity-oriented that the utility model is used for fixing cutter is assemblied on the tool rest also through corresponding screw locking or the release that is provided with of tool rest; The position of cutter in the cutter groove of movable block regulated through adjustment screw; Thereby when regulating cutter processing radius; Elder generation's movable block is regulated the position of cutter, through the adjustment screw on the moving slider processing radius of cutter is finely tuned behind the screw on the tool rest of screwing again, and realizes regulating fast and accurately the processing radius of cutter.

Description of drawings

Fig. 1 is the structural representation of the embodiment intermediate slide of cutter.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to describe.

Embodiment: as shown in Figure 1; The movable block guide groove 3 interior guiding that the tool rest 1 of the utility model knife rest is offered along horizontal linear are equipped with movable block 2; The guide direction of movable block guide groove 3 is a fore-and-aft direction, and movable block 2 cooperates with tool rest 1 guiding and fixing through the housing screw on the tool rest 18 along the guide direction of movable block guide groove 3, and movable block 2 front ends offer and are used for the cutter groove 4 that activity-oriented assembles cutter 9; The guide direction of cutter groove 4 is consistent with the guide direction of movable block guide groove 3; Cutter 9 guiding is assemblied in the cutter groove 4 and is fixing through the hold-down screw 5 that wears on cutter groove 4 cell walls, movable block 2 rear ends offer extend forward screwed hole 2-1, be installed with adjustment screw 6 among the screwed hole 2-1; The front end of screwed hole 2-1 is between cutter groove 4 and movable block 3 rear end faces; Be communicated with unthreaded hole 2-2 between screwed hole 2-1 and the cutter groove 4, be equipped with the fine setting fore-set 7 that is used for the jacking force of adjustment screw is passed to corresponding cutters among the unthreaded hole 2-2, that is to say that the motion of fine setting fore-set 7 is consistent with adjustment screw 6.

Movable block guide groove 3 bottom lands on the tool rest 1 are the plane that is parallel to tool rest 1 end face, and the both sides cell wall is parallel to each other and is vertical with bottom land.

In the specific implementation, roughly adjust through 2 pairs of cutter 9 positions of movable block of moving in the movable block guide groove 3, then through screwing or unscrewing adjustment screw 6 trimming tool bits 9 front and back positions.

The utility model can accurately be regulated the tool position according to the pitch of screw thread when regulating the tool position, and coarse adjustment is accomplished through regulating different members with fine setting in reconciling, and governing speed is fast.

In the foregoing description, movable block is installed in the movable block guide groove on the tool rest, and movable block guide groove cell wall plane is a rectangle plane, and in other embodiments, the cell wall plane of movable block guide groove also can be arc-shaped curved surface; Movable block also can be installed in the movable block pilot hole on the tool rest.

In the foregoing description; Cutter is regulated the cutter front and back position through the fine setting fore-set in the adjustment screw pushing tow unthreaded hole in the screwed hole; In other embodiments; Can not establish unthreaded hole and make the screwed hole cutter groove that goes directly, can use long adjustment screw directly to penetrate in the cutter groove like this and directly join on the top with corresponding cutters, what also can cooperate in the screwed hole intermediate gap wears the fine setting fore-set.
