Abstract

The utility model relates to an instrument machine tool, which aims to provide a slag-proof device on a multi-surface cutting instrument machine tool. The slag-proof device comprises a fixing seat 1 and a slag-proof plate 2 which is sleeved in the fixing seat 1 and can be moved from left to right, the fixing seat 1 is equipped with a slotted hole 3, the slag-proof plate 2 is equipped with a circular hole 4, and the circular hole 4 is in the range of the slotted hole 3. After employing the slag-proof device of the utility model, a power transmission shaft of the machine tool penetrates through the circular hole on the slag-proof plate and is sleeved in the slotted hole of the fixing seat, when a gear transmission case body and the power transmission shaft perform relative motion, the power transmission shaft drives the slag-proof plate to move inside the fixing seat, and thereby preventing iron slag outside from intruding.

Description

Anti-bits device on a kind of many flush cuts watchmaker's machine tool

Technical field

The utility model relates to a kind of watchmaker's machine tool, more particularly, is the anti-bits device on a kind of many flush cuts watchmaker's machine tool.

Background technology

Watchmaker's machine tool is a kind of equipment of common processing small-sized machine part.Common multilevel part, shape such as flat, cubic, six sides, all directions, it all is the method that adopts calibration to carry out milling, therefore its work efficiency is lower, if finish large batch of part production, processing has just become a very big problem, the watchmaker's machine tool that has occurred a kind of many flush cuts in the nearest thus watchmaker's machine tool production industry, its principle is to utilize the rotating ratio of power transmission shaft and work spindle, and diaxon rotates in the same way, finishes when realizing the many flush cut of workpiece.But the structure of this class lathe is all fairly simple at present, is not particularly considering aspect the anti-bits more.Because work spindle need laterally move the processing of finishing the workpiece cutting depth, therefore the casing of the gear that links to each other of work spindle can not fix with the power transmission shaft of machine tool chief axis and link to each other, be necessary for the laterally mobile space of leaving of power transmission shaft at the opening part of tank wall, this space is bigger usually, is generally the mounting hole of strip.As shown in Figure 5, work spindle 6 links to each other with gear 7, is fixed on after power transmission shaft 9 on the machine tool chief axis runs through the casing that enters gear 7, cooperates with the travelling gear of case inside.Carry out cutting depth when the workpiece traverse feed and add man-hour, gear 7 is being driven together by work spindle 6 and is laterally moving, produce relative displacement between the tank wall of gear 7 and the power transmission shaft 9, therefore the axle on the tank wall is worn the mounting hole 8 that a kind of horizontal strip is processed at mouthful place usually, so that power transmission shaft 9 is realized freedom of movement therein; The size of mounting hole 8 is relevant with the impulse stroke of axle, therefore will be much larger than the diameter of axle of power transmission shaft 9 on length; Move to an end of mounting hole 8 when power transmission shaft 9 after, the other end of mounting hole 8 can and axle between vacate bigger space, therefore the iron filings that part processing produces can be easy to splash thus and enter box house, influence the operate as normal of machine tool.

The utility model content

The purpose of this utility model is in order to overcome deficiency of the prior art, and the anti-bits device on a kind of simple in structure and many flush cuts watchmaker's machine tool that anti-bits effect is good is provided.

The purpose of this utility model is to be achieved by following technical scheme:

Anti-bits device on a kind of many flush cuts watchmaker's machine tool, but comprise holder 1 and the anti-bits plate 2 that is enclosed within move left and right in the holder 1; Described holder 1 is provided with elongated hole 3, and described anti-bits plate 2 is provided with circular hole 4; Described circular hole 4 is in the scope of elongated hole 3.

As a kind of improvement of the present utility model, described elongated hole 3 is a kind of mounting hole shape.

As a kind of improvement of the present utility model, two outstanding grooves 5 that form in limit up and down of described holder 1; But described anti-bits plate 2 is fixed in the groove 5 and move left and right.

As a kind of improvement of the present utility model, described holder 1 and anti-bits plate 2 are stainless steel material.

Compared with prior art, the beneficial effects of the utility model are:

1. at the tank wall axle tapping of gear anti-bits device of the present utility model is installed, the circular hole that the power transmission shaft of lathe passes on the anti-bits plate packs in the elongated hole of holder again, produce when relatively moving when gear drive casing and power transmission shaft like this, power transmission shaft is driving anti-bits plate and is moving in holder, has stoped flying into of outside iron filings.

2. the utility model is made simply, and with low cost, structure is both artistic and practical.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

As shown in Figure 1, but the anti-bits device on many flush cuts watchmaker's machine tool of the present utility model comprise holder 1 and be enclosed within the anti-bits plate 2 of move left and right in the holder 1; Holder 1 is rectangle as shown in Figure 2, and the middle part laterally is provided with the mounting hole 3 of strip; The length of mounting hole 3 can be slightly larger than the maximum displacement of the power transmission shaft 9 in Fig. 5, highly is slightly larger than the diameter of axle of this power transmission shaft 9; Anti-bits plate 2 as shown in Figure 4, also be rectangle, shape is littler than holder 1, and the middle part of anti-bits plate 2 is provided with the circular hole 4 of the diameter of axle that is slightly larger than power transmission shaft 9, and anti-bits plate 2 is when sliding about in holder 1, and circular hole 4 is in the scope of mounting hole 3 all the time.

Holder 1 and anti-bits plate 2 are made for stainless steel material, and be firmly attractive in appearance; The outstanding grooves 5 that form on two limits up and down of holder 1, as shown in Figure 3, being fixed on up and down in the groove 5 of anti-bits plate 2, about can slide along groove 5.

As shown in Figure 6 and Figure 7, anti-bits device of the present utility model is installed in the tank wall axle tapping of gear 7, and four corners of holder 1 have aperture, are fixed on the tank wall with screw; After power transmission shaft 9 passes anti-circular hole 4 of considering to be worth doing on the plate 2, pack in the mounting hole 3 of holder 1 with anti-bits plate 2 again; Like this when casing and power transmission shaft 9 have horizontal relative displacement, power transmission shaft 9 is driving anti-bits plate 2 all the time and is horizontally slipping along groove 5 in holder 1, because circular hole 4 is in the scope of mounting hole 3 all the time, therefore anti-bits plate 2 also closes mounting hole 3 all the time in sliding, and stops outside iron filings to splash and enters.

At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
