Abstract

The utility model discloses a mechanical master form for a frame planer, which is used for processing the molding surfaces of workpieces, such as a curved surface, etc. The utility model is composed of a knife head, a knife bar, a slide plate, a slide block, etc. The tool bar with a cone and a guide sleeve is fixed on a knife plate of a knife feeding frame on a cross beam of a planer. A spring is fixed between the upper end of the guide sleeve and a bearing ear plate through a positioning rod. The slide block with a taper hole seat is arranged in a curved groove on a moulding plate which is clamped by a clamping plate. The moulding plate is fixed on another knife feeding frame on the cross beam of the planer through a screw bolt. A cone is matched with the taper hole seat to form a clutch.

Description

Metal-planing machine mechanical type pattern

The utility model relates to the direct copy that a kind of machine tooling attachment device, particularly metal-planing machine are used.

Metal-planing machine not only will be used to the plane of planing, and also can be used for the processing of forming face such as curved.If need forming faces such as processing is curved, generally be to adopt that line back manual control is advanced, penetration of a cutting tool, or on lathe, install the fluid pressure type pattern additional and process.The former operates difficultly, and machining accuracy, fineness are poor; The latter is equipment complexity, mounting or dismounting inconvenience then, and unstable properties, and crudy often is difficult to meet the requirements.

The purpose of this utility model provide a kind of simple in structure, mounting or dismounting are convenient, and mechanical type pattern that forming face uses such as the reliable metal-planing machine processing of processing characteristics is curved.

For achieving the above object, the utility model has designed following scheme: the metal-planing machine mechanical type pattern of being made up of parts such as cutter head, knife bar, template and slide blocks, slide block is placed in the shaped groove on the template, template is fixed on the feed support on the planer crossbeam, the knife bar that the upper end has cone is installed in the guide pin bushing, and be fixed on via guide pin bushing on the lifts plate of another feed support on the planer crossbeam, have the taper hole seat on the slide block, cone cooperates with the taper hole seat forms clutch, clutch mutually between cone and the taper hole seat, but do not deviate from; The upper surface of guide pin bushing and fixedly by backstay knife bar is installed between the otic placode of knife bar both sides and is supported spring.

By the clutch that cone and taper hole seat are formed, cone---taper hole can be circular cone, square awl, triangular pyramidal or monocline wedge, diclinic wedge shape.

The utility model is stable and reliable for performance, and forming face such as curved can improve machining accuracy and fineness in order to plane; Simple in structure because of it, not only easy for operation, and be easy on lathe, install and remove, can be with using with dress, thus improve the heavy duty machine tools utilization rate.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the side view of the utility model planing state.

Fig. 3 is the side view of the utility model withdrawing state.

Below in conjunction with accompanying drawing the utility model is further described.

As depicted in figs. 1 and 2, upper end knife bar 2 that cone 5 is housed is installed on the lifts plate 19 of a feed support 20 on the planer crossbeam by bolt 4 via guide pin bushing 3.Backstay 15 is fixed on the last transverse plane of guide pin bushing 3, and the top of backstay 15 is provided with adjusting nut 18, is welded with load otic placode 17 on the two sides of knife bar 2 shafts, and spring 16 is installed on the backstay 15.The slide block 7 that has taper hole seat 6 is placed in the shaped groove 9 ' of template 9, and clamping plate 10 clamp template 9 by bolt 11, by long sleeve 12, short sleeve 13 and bolt 14 with template 9 positioning and fixing on another feed support 20 ' on the planer crossbeam.Knife bar 2 is connected by the clutch of being made up of cone 5 and taper hole seat 6 with slide block 7.Taper hole seat 6 is with the hold-down nut underlying pad of slide block 7 pointer 8 of holding concurrently.

Add man-hour, planing tool 1 is installed on the knife bar 2, lifts plate 19 is close on the feed support 20, and knife bar 2 is in vertical position, taper hole seat 6 driving fit mutually on cone 5 and the slide block 7 of its upper end.Start feed support 20, be installed in knife bar 2 on the lifts plate 19 along with traversing, produce a feed (as shown in Figure 1), knife bar 2 slides in the shaped groove 9 ' of template 9 by the clutch drive slide block of being made up of cone 5 and taper hole seat 67 simultaneously, each slip of slide block 7 causes moving up and down of knife bar 2 self, generates different bites.

Because the cone 5 of knife bar 2 upper ends can be with 6 separation of the taper hole seat on the slide block 7 and with 19 revolutions of lifts plate, so lifts plate 19 is unhinderedly takeoff (as shown in Figure 3) after lathe bed 21 right laterals, 1 pair of workpiece 22 of planing tool are planed.

When lifts plate 19 takeoff, though cone 5 is separated with taper hole seat 6, cone 5 was not deviate from the scope of taper hole seat 6, and knife bar 2 can keep because of the support of the spring 16 that is placed in guide pin bushing 3 upper ends, shaft both sides and pushed up the upper right wall that is attached to taper hole seat 6 this moment.But the center of turn nut 18 adjustment cone 5, taper hole seat 6.

Takeoff at lifts plate 19, when planing tool 1 was lifted away from workpiece 22 surfaces, lathe bed 21 was done the idle running reversion left.Backhaul finishes, and lifts plate 19 falls after rise, and is multiple to original position, and knife bar 2 is along with turning anticlockwise, and its cone 5 is wedged and driving fit mutually from outside to inside along taper hole seat 6.

Repeat said process, all machine until workpiece 22 curved surfaces.
