The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment, the utility model is further described.

A kind of CNC milling machine cutter table as shown in Figure 1 and Figure 2, comprise a table body 1, be fixedly connected with a lock tool rest 2 at the left side edge near operating personnel on the desktop of table body rectangle, with for by Cutting tool installation manner to handle of a knife, or remove cutter from handle of a knife, under the desktop of table body, right side is storage cabinet 3, it can be used for placing the heavier article of handle of a knife one class, in order to avoid fall damage, under desktop left side three open-minded, place the larger article of some profiles to facilitate.Pick and place article for convenient from storage cabinet inside, we can arrange respectively the cabinet door 31 of splitting on close operating personnel one side of storage cabinet and adjacent two, right side exposed lateral side, and the top of while in storage cabinet arranges illuminating lamp.On the table body away from operating personnel's forward edge setting support 4 straight up, support is frame structure, comprise three vertical vertical rods 41 and the cross bar 42 that is connected three vertical rod upper ends, between the vertical rod of right side vertical rod and centre, two layers of shelf 43 are set, a plurality of counterbores are set on the shelf of upper strata, to insert the cutter of all size, there are a plurality of cavitys on lower floor's shelf, to place the small article of sleeve one class.Certainly, chute can be set in vertical rod or equally spaced locating hole is set, so that shelf moves up and down adjusting position, thereby can adapt to the needs of the article of placing differing heights.In addition, between left side vertical rod and middle vertical rod, arrange and the shelf vertical link plate 44 that is arranged side by side, link plate is provided with some pegs 45, in order to hang up the common tool such as hacksaw, iron hammer one class.Also have, we can arrange corresponding lighting on the cross bar of support, and picking and placeing of the article on Portable rack and link plate can be used as the illumination of whole desktop simultaneously on the one hand.

In order to make link plate adapt to hanging up of variety classes instrument, we can adopt following two schemes:

The first scheme, we can arrange the hanging hole 441 of some rectangular arrays on link plate, and peg is detachably connected on hanging hole, so that according to position and the quantity that need to freely change peg that hang up article.Particularly, link plate can adopt existing punched-plate to make, and peg can be made into multidiameter, its less root inserts in hanging hole, and fix with nut in the end that passes link plate, or grab peg and can directly adopt screw, on peg, the threaded end of tool is inserted in hanging hole, and the both sides, front and back that are positioned at link plate on peg are fixed with nut respectively.

First scheme, as shown in Fig. 3 Fig. 4, we also can arrange on the surface of link plate mutual intersection and be latticed T shape chute 442, in order to adjust the position of peg on link plate, peg comprises that T shape sliding sleeve 451, a root be slidably connected in T shape chute is located in the carriage release lever 452 in T shape sliding sleeve, like this, T shape sliding sleeve can move together with carriage release lever in T shape chute, thereby changes the position of peg.In order to be conducive to the position adjustment of peg, T shape chute is mutually intersected and forms by the first chute 443 and second chute 444 of some equidistant arrangements, and the first chute and the second chute equate with the angle of horizontal plane, thereby make the first chute and the second chute mutually intersect to form the latticed of rhombus, preferably, mutually vertical between the first chute and the second chute, like this, when two pegs move along first chute and second chute respectively, not only distance each other can be changed but also the position on link plate can be changed, and when two pegs move along the first different chutes or the second chute respectively, can change the position of peg level and vertical direction on link plate simultaneously.Particularly, when running into the article that need to just can hang up with three pegs, as long as a peg is positioned on the crosspoint of the first chute and the second chute, can make three pegs form easily the triangular arrangement of different sizes on the four direction up and down in crosspoint, thereby facilitate hanging up of various article.Certainly, in order to make peg, in T shape chute, reliably locate, as shown in Figure 4, we also need be in the bottom surface of T shape chute vertically arrange some location counterbore 445 equally spacedly along T shape chute, the root of carriage release lever is suitable with the location counterbore, like this, when the root of carriage release lever fits in the counterbore of location, can make the peg location.In addition, we also can arrange magnet 453 on the end face of carriage release lever root, certainly, the polar orientation of magnet is the axial of carriage release lever, be connected thereby make magnet form magnetic with the bottom surface of location counterbore, to avoid the loosening of carriage release lever, guarantee the reliable location of peg on link plate.When needs are adjusted the position of peg, operating personnel can firmly pull out carriage release lever its bottom surface and location counterbore are separated, can make carriage release lever slide in T shape chute and move to the position needed in company with T shape, and again carriage release lever is fitted in the counterbore of corresponding location, in order to peg is reorientated.For the ease of the carriage release lever that magnetic is linked together, with the location counterbore, be separated, as shown in Figure 5, we can make circular by the magnet of carriage release lever root, and at circular magnet end face, two circular saws 454 are set, circular saw has the flank of tooth of two inclinations, thereby making circular saw cross section along the circumferential direction is triangle, and the gradient of a lateral tooth flank is less, thereby form slide surface 455, the opposite side flank of tooth gradient is larger, itself and the carriage release lever angle between axially can be between the 0-5 degree, the corresponding central angle of each circular saw is 180 degree, correspondingly, as shown in Figure 4, we need arrange the band saw teeth groove 446 coordinated with circular saw in the bottom surface of location counterbore, be understandable that, there is larger magnetic attraction between binding face corresponding to the slide surface of circular saw and band saw teeth groove, and its external force required along tangential slippage is very little, magnetic attraction on the opposite side flank of tooth and band saw teeth groove between the binding face of correspondence is minimum.Like this, when we need to adjust the position of peg, available have gentle hands loose ground rotates carriage release lever, now between the slide surface on circular saw and binding face corresponding on the band saw teeth groove, can produce relative tangential displacement, thereby make carriage release lever produce axial outer moving, the opposite side flank of tooth of circular saw separates with the binding face on the band saw teeth groove, the angle of rotating when carriage release lever approaches 180 while spending, the outset of carriage release lever is from the tooth depth that approaches circular saw, and the fitting area minimum between the binding face of the slide surface of circular saw and band saw teeth groove, now can like a cork carriage release lever be pulled out, make it leave the location counterbore fully, thereby mobile peg easily.

In addition, as shown in Figure 5, we also can arrange perforation radially in the end of carriage release lever, like this, when the mobile peg of needs, can wear rod member as the handle rotated in perforation, to facilitate the rotation of carriage release lever, or rod member can be used as the hook of a peg, avoids falling of article.

As shown in Figure 6, fixing lock tool rest on the table comprises a vertical horizontal dockboard 21, the fixed head 23 that flatly is connected to the vertical dockboard 22 of horizontal dockboard top edge and flatly is connected to horizontal dockboard lower limb, thereby make to lock the U-shaped that tool rest integral body is horizontal placement, the U-bolt groove can be offered in the both sides of fixed head, to facilitate, is fixed by bolts on desktop.Locating hole 211 with the handle of a knife adaptation is set in the middle of horizontal dockboard, and the medial surface of locating hole is provided with the positioning convex 212 with the positioning spline adaptation of handle of a knife, with the horizontal handling cutter for backward pulling type tool holder.The middle setting of vertical dockboard can be held the maintainance set 221 of handle of a knife, and the side at maintainance set arranges locking structure simultaneously.Like this, when the vertical mounting cutter of needs, we can insert handle of a knife in maintainance set, then with locking structure, make the handle of a knife location, and available spanner is locked cutter.We know, handle of a knife has a holding ring between the front end of holding cutter and the tail end that is connected with machine tool chief axis, and the side of front end has two keyways that extend to holding ring, during due to horizontal handling cutter, the front end of handle of a knife holding cutter gos deep in the locating hole of horizontal dockboard, and operating personnel only need tighten the installation that the screw of the handle of a knife tail end exposed can complete cutter, thus the keyway of handle of a knife front end side easily screens on locator protrusions.And during vertical handling cutter, the tail end that handle of a knife is connected with machine tool chief axis gos deep in the maintainance set of vertical dockboard, so the keyway on handle of a knife is exposed at outward outside maintainance set, and we need to locate handle of a knife with corresponding locking structure.

In order to make the handle of a knife location when the vertical handling cutter, we can adopt following two schemes:

The first scheme, we can be arranged on locking structure on vertical dockboard, so that utilizing locking structure directly locates handle of a knife, particularly, as shown in Figure 6, locking structure comprises and is arranged on the tapered end seat 51 that vertical dockboard upper surface is positioned at the maintainance set side, the top of tapered end seat arranges U-shaped groove 511, be provided with turning cylinder 53 in U-shaped groove, be rotationally connected a tapered end 52 on turning cylinder, the keyway adaptation of the head of tapered end and handle of a knife.At ordinary times, the state of tapered end in outwards opening, when handle of a knife is put in maintainance set, get final product rotational lock head, the head of tapered end snapped in the keyway of handle of a knife side, thereby handle of a knife is located reliably, prevents that it from rotating.And, after having loaded and unloaded, only need upwards lift handle of a knife, can drive the outside upset of tapered end to open, thereby easily handle of a knife be taken out.Certainly, we also can arrange a tapered end handle 54 on tapered end, to facilitate the rotation of tapered end.

In addition, we can realize by a set of linkage the automatic turning of tapered end, to further facilitate the locking location to handle of a knife, increase work efficiency.Particularly, as shown in Figure 7, we can first connect a stiffener 24 on the horizontal dockboard one vertical edge of side, the top edge of stiffener connects vertical dockboard, the lower limb of stiffener is connected and fixed plate, and tapered end is connected an end and stretches out and form the first swing arm 55 with turning cylinder, and between tapered end and the first swing arm shape is in an angle, when the first swing arm during in level, the open mode of tapered end in above turning over.In addition, bearing block 242 is set on the medial surface of stiffener, the swinging axle 241 upper and lower corresponding with turning cylinder is set on bearing block, one end of one second swing arm 56 is rotatably connected on swinging axle, simultaneously, the two ends of one synchronous connecting rod 57 are hinged with the free end of the first swing arm and the second swing arm respectively, and the second swing arm and the first swing arm are parallel to each other and are equal in length, thereby first, second swing arm can synchronously be swung with angle ground.Further, the second swing arm is connected an end and extends internally and form depression bar 58 with swinging axle, maintainance set stretches out on the lateral surface of vertical dockboard bottom surface section upper sliding seat 225 and the lower slider seat 226 of arranging vertically is set, one vertical slide bar 227 is slidably connected at, on the lower slider seat, arrange and be positioned on slide bar, bulge loop 228 between the lower slider seat, one back-moving spring 229 is set on slide bar, the upper end of back-moving spring is against bulge loop, the lower end abutment lower slider seat of back-moving spring, thereby making slide bar move to bulge loop on automatically under the promotion of back-moving spring contacts with upper sliding seat, the end that slide bar stretches out the lower slider seat arranges a horizontal transiting rod 59 again, the inner of transiting rod is positioned at the maintainance set below, the outer end of transiting rod is provided with the contact 591 of downward butt depression bar.While being inserted in maintainance set when the needs mounting cutter by handle of a knife, the inner of the lower end contact transiting rod of handle of a knife, thereby the elastic force that overcomes back-moving spring with moving slide-bar vertically moves down, now the contact of transiting rod outer end promotes depression bar downwards, and then drive the second swing arm and upwards rotate, and synchronously upwards rotate by driving the first swing arm under the effect of synchronising (connecting) rod, correspondingly, tapered end rotates and automatically snaps onto the location of handle of a knife side with in keyway.When upwards extracting handle of a knife, handle of a knife can promote tapered end and make depression bar synchronously upwards rotate and reset by the first swing arm, synchronising (connecting) rod, the second swing arm, and back-moving spring promotes slide bar and drive on transiting rod to move and reset.Position by the appropriate design contact on transiting rod, can make contact the acting force arm of depression bar is less than to the radius of gyration of tapered end end, and then make less the moving up and down of contact can form larger depression bar pendulum angle, correspondingly, tapered end also synchronously forms a larger pendulum angle, thereby can guarantee when the handle of a knife lower end contacts with transiting rod, keyway on handle of a knife has been positioned at the side of tapered end, when handle of a knife continues to move down less stroke, tapered end can rotate rapidly and screens is arrived in the keyway of handle of a knife.Otherwise, while carrying on handle of a knife, move speed on transiting rod and will be slower than the speed that tapered end is outwards opened, thereby can avoid producing and interfering with tapered end.

It should be noted that, we can arrange in the both sides of maintainance set two cover locking structures, in order to, to the screens simultaneously of the positioning spline of handle of a knife both sides, make the location of handle of a knife more reliable, stressed more even.Certainly, now need on the vertical edge of horizontal dockboard opposite side, connect a stiffener, and another set of linkage correspondingly is set, to realize the automatic locking of two cover lockable mechanisms to maintainance set

First scheme, we can be first by maintainance set by bearing hinge joint on vertical dockboard, then locking structure is arranged on maintainance set, in order to utilize locking structure that handle of a knife is positioned on maintainance set, then by determining accordingly torque structure, maintainance set is located.

Particularly, as shown in Figure 8, we can arrange a baffle ring 222 on maintainance set stretches out the lateral surface of vertical dockboard upper surface portion, the lower surface of baffle ring abuts in vertical dockboard upper surface, and locking structure comprises the tapered end seat 51 be arranged on baffle ring, and the top of tapered end seat arranges U-shaped groove 511, be provided with turning cylinder 53 in U-shaped groove, be rotationally connected a tapered end 52 on turning cylinder, the keyway adaptation of the head of tapered end and handle of a knife, arrange tapered end handle 54 on tapered end.Like this, when handle of a knife is put in maintainance set, get final product rotational lock head, the head of tapered end is snapped in the keyway of handle of a knife both sides, thereby handle of a knife is positioned on maintainance set reliably.With the similar ground of last scheme, we can arrange in the both sides of maintainance set two cover locking structures, to the positioning spline screens simultaneously of handle of a knife both sides.In addition, we need to arrange axial arranged locating slot 223 on maintainance set stretches out the lateral surface of vertical dockboard bottom surface section, as shown in Figure 9, the cross section of locating slot is roughly triangular in shape, locating slot comprises that a basic spacing side that becomes radially to extend and one extend to the bottom surface of maintainance set outer surface obliquely by base, spacing side, thereby makes the locating slot degree of depth diametrically along the circumferential direction by spacing side one side to opposite side, progressively be decreased to zero.As shown in Figure 8, determine torque structure and comprise the stiffener 24 be connected on the horizontal dockboard one vertical edge of side, the top edge of stiffener connects vertical dockboard, the lower limb of stiffener is connected and fixed plate, a horizontal positional cylinder 61 is set on stiffener, the piston rod of positional cylinder inwardly passes stiffener, and the end of piston rod is resisted against on the locating slot bottom surface of maintainance set, thereby can avoid the rotation of maintainance set.In addition, we also need to arrange regularly on the table a vertical pressurizing cylinder 62, on pressurizing cylinder piston rod straight up, snap ring 621 is set, and is positioned at the sheathed some counterweight rings 63 of part above snap ring at the piston rod of pressurizing cylinder, thereby make pressurizing cylinder produce corresponding oil pressure.Certainly, we also need with positional cylinder between the pipeline that is connected use is set, one end of pipeline is communicated with on pressurizing cylinder the lower cavity away from piston rod, the other end of pipeline is communicated with on positional cylinder the rear portion cavity away from piston rod, thereby make the oil pressure of pressurizing cylinder can be delivered on positional cylinder, and then make the piston rod of positional cylinder tightly against the locating slot of maintainance set, avoid the rotation of maintainance set.Locking nut on the handle of a knife that screws up with a wrench is during with mounting cutter, maintainance set is subject to the moment of torsion that handle of a knife passes over, the bottom surface that locating slot tilts produces an outside thrust to the positional cylinder piston rod, when the moment of torsion of spanner is greater than setting value, the thrust that the locating slot bottom surface produces the positional cylinder piston rod will be greater than the pressure of positional cylinder, thereby the positional cylinder piston rod is outwards moved, maintainance set rotates, thereby can effectively guarantee that the locking torque of handle of a knife remains on a suitable setting value.And while needing the dismounting cutter, spanner rotates backward, because the side of locating slot roughly becomes radially, thereby the end of piston rod can't outwards move, thereby can avoid the rotation of maintainance set.In addition, we also can arrange in the piston rod end of positional cylinder a roller 611, to reduce its wearing and tearing to the locating slot bottom surface.And the weight of counterweight ring can be set according to the needed fastening torque of different cutters, like this, when the cutter of different size is installed, can choose the counterweight ring of corresponding weight.

Further, we also can arrange in the inboard of maintainance set flexible cushion collar 224, and cushion collar can be made with rubber, thus while avoiding loading and unloading cutter to the wearing and tearing of handle of a knife.

Finally, as shown in Figure 2, we also can arrange inlet suction port 71 and air outlet adapter 72 on the limit, left side of table body, between inlet suction port and air outlet adapter, by tracheae, be communicated with, inlet suction port can be used for connecting compression gas pipe, air outlet adapter can be used for connecting pneumatic tool, thereby facilitates the use of the instruments such as air blow gun, pneumatic sieve are criticized, pneumatic grinding head.
