Description

A kind of multistation self-locking knife rest

Technical field

The invention belongs to mechanical engineering field, 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 gradually rust, have impact on the efficiency of processing, the surface quality etc. of part, the most even can damage cutter so that it is cannot re-use, cause damage, therefore, it is very important that cutter to rust sharpens timely, has the most not only saved the cost of cutter, also ensure that the quality of processing simultaneously.

Knife machine is used to sharpen 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 during the different cutter of a kind of simple in construction, sharpening, change convenient knife-clamping device.

Summary of the invention

It is contemplated that design one 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, the invention provides following improvement project: casing mainly includes upper box, middle casing, lower box three part, the locking of upper box and middle casing, lower box is to be realized by 4 swing arm locking devices around upper box, it is made up of swing arm, knob, spring, and gear drive is positioned at casing；Splined shaft is connected with gear shaft b, and socket cover is connected with gear shaft b, and spring is positioned in gear shaft b, and splined shaft realizes its stretching in gear shaft b by compression spring, and the process of splined shaft compression spring is realized by driving lever；Gear drive is mainly made up of rocking handle, gear shaft, gear etc., drives the rotation of splined shaft by the transmission that connects of three gears；Locking device is made up of knob, check lock lever and spring, can be realized the locking of upper box by rotational lock bar；Four kinds of tool mountings are respectively the circular milling fixture of handle, the milling fixture of conical grip, fixture for turning tool, Graver clamp, can carry out rotating sharpening by band cutter when splined shaft is connected with milling fixture and Graver clamp.

The actual gain that the present invention 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 the present invention done detailed introduction: as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, 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 rotary shafts, 21 driving levers.nullMultistation self-locking knife rest is mounted in work on the turntable seat of knife machine knife rest，Casing in 4 upper boxes and 3、2 lower boxes are sequentially connected with，20 rotary shafts run through 3 casings，4 upper boxes can be rotated around 20 rotary shafts by 11 bearings，During work, casing and 2 lower boxes do not rotate in 3，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, 21 driving levers are allocated in draw-in groove，Now 13 springs are compressed，14 splined shafts and tool mounting are in released state，This knife-clamping device has four chucks to be respectively 16 taper shank shape milling fixtures、17 circle handle type milling fixtures、18 fixture for turning tools and 19 Graver clamps，When cutter chuck or graver chuck are gone to operating position，Driving lever is transferred to from draw-in groove，During now under the elastic force effect of 13 springs, 14 splined shafts stretch into the rotating shaft of tool mounting，8 gear shaft a are driven to rotate by rotating 1 rocking handle，8 gear shaft a and 9 gears connect，9 gears and 10 gear shaft b connect，Gear shaft and 14 splined shafts connect，Thus driven the rotation of tool mounting，Realize the rotation sharpening of milling cutter or graver，Wherein 14 splined shaft、13 springs are in 10 gear shaft b，By 12 spiral covers, they are enclosed in 10 gear shaft b.

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 5 knobs, 6 swing arm springs, 7 swing arm compositions, 5 knobs and 7 swing arms 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 rotation to latched position, when upper box conversion 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.
