Description

A kind of multistation self-locking knife rest

Technical field

This utility model belongs to mechanical engineering field, more specifically to a kind of multistation self-locking knife rest。

Background technology

Cutter has important function in machining, the quality of cutter directly influences the quality of the quality of part to be processed, and cutter in use can rust gradually, have impact on the efficiency of processing, the surface quality etc. of part, sometimes cutter can even be damaged so that it is cannot re-use, cause damage, therefore, it is very important that cutter to rust carries out sharpening timely, has so not only saved the cost of cutter, also ensure that the quality of processing simultaneously。

Knife machine is used to sharpening cutter, and knife rest is the core of knife machine, and multistation self-locking knife rest is mainly placed on the knife rest of knife machine, is used for clamping different types of cutter and sharpens。Knife-clamping device on current knife machine knife rest can only clamp a kind of cutter and sharpen, need to change different fixtures when the different cutter of sharpening, dismounting and installation inconvenience, clamp structure is complicated, add cost, have impact on working (machining) efficiency, it is therefore desirable to when a kind of simple in construction, sharpening difference cutter, change convenient knife-clamping device。

Summary of the invention

It is intended to design one at this utility model and can eliminate disadvantages mentioned above, simple in construction, it is possible to four kinds of different cutters of clamping, the multistation self-locking knife rest that work efficiency is high and economic performance is excellent。

For achieving the above object, this utility model provides following improvement project: a kind of multistation self-locking knife rest mainly includes casing, gear transmission structure, splined shaft, locking device, fixture for turning tool, circle shank milling cutter fixture, taper-shank cutter fixture, Graver clamp, described gear transmission structure is connected with gear shaft b, gear shaft b is connected with splined shaft, driving lever is enclosed within splined shaft, and splined shaft can be connected with circle shank milling cutter fixture, taper-shank cutter fixture, Graver clamp。Wherein casing is made up of upper box, middle casing, lower box three part, rotate upper box select need tool mounting, when sharpen milling cutter, graver time, stir driving lever and rotate rocking handle realize cutter rotation sharpening。Built-in spring in splined shaft, stir driving lever compression or pull-off spring thus realizing the movement of splined shaft, the locking of three casings is to be realized by 4 swing arm locking devices around upper box, this locking device is made up of swing arm, knob, spring, gear drive is mainly made up of rocking handle, gear shaft, gear etc., the rotation of splined shaft is driven, four kinds of tool mountings respectively round shank milling cutter fixture, taper-shank cutter fixture, fixture for turning tool, Graver clamps by the transmission that connects of three gears。

The actual gain that this utility model produces is: when different cutters are sharpened by (1), rotates upper box and can realize the switching of different fixture, facilitates the sharpening of variety classes cutter, rotary type tower knife-clamping device simple in construction, effectively raise working (machining) efficiency。(2) locking of casing is locked by the swing arm locking device of surrounding, simple and convenient。

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model done detailed introduction: as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, a kind of multistation self-locking knife rest, primary structure includes: 1 rocking handle, 2 lower boxes, casing in 3,4 upper boxes, 5 knobs, 6 swing arm springs, 7 swing arms, 8 gear shaft a, 9 gears, 10 gear shaft b, 11 bearings, 12 spiral covers, 13 springs, 14 splined shafts, 15 sliding bearings, 16 taper shank shape milling fixtures, 17 circle handle type milling fixtures, 18 fixture for turning tools, 19 Graver clamps, 20 rotating shafts, 21 driving levers。Multistation self-locking knife rest is mounted on the turntable seat of knife machine knife rest work, upper box 4 and middle casing 3, lower box 2 is sequentially connected with, rotating shaft 20 runs through 3 casings, upper box 4 can be rotated around rotating shaft 20 by bearing 11, in during work, casing 3 and lower box 2 do not rotate, moving integrally of knife-clamping device is realized by knife rest, during the work of rotary type tower knife-clamping device, needs according to processing select corresponding tool mounting, rotate upper box and gone to operating position, in the process rotated, driving lever 21 is allocated in draw-in groove, now spring 13 is compressed, splined shaft 14 and tool mounting are in released state, this knife-clamping device has four chucks respectively taper shank shape milling fixture 16, circle handle type milling fixture 17, fixture for turning tool 18 and Graver clamp 19, when cutter chuck or graver chuck are gone to operating position, driving lever is transferred to from draw-in groove, now under the elastic force effect of spring 13, splined shaft 14 stretches in the rotating shaft of tool mounting, rotate by rotating rocking handle 1 driven gear axle a8, gear shaft a8 is connected with gear 9, gear 9 is connected with gear shaft b10, gear shaft b10 is connected with splined shaft 14, thus having driven the rotation of tool mounting, realize the rotation sharpening of milling cutter or graver, wherein splined shaft 14, spring 13 is in gear shaft b10, by 12 spiral covers, they are enclosed in gear shaft b10。After upper box goes to operating position, its position can be fixed by the swing arm locking device of surrounding, swing arm locking device is by knob 5, swing arm spring 6, swing arm 7 forms, knob 5 and swing arm 7 are connected together by helicitic texture, swing arm moves along groove in hole, when upper box is locked, spring is compressed swing arm lower end removal hole slot and is rotated to latched position, when upper box converts station, rotating swing arm lower end and retreat in hole slot, under the elastic force of spring, swing arm is just upspring, then upper box is just relaxed, and can be rotated。
