Description

The general inclined-plane frock of milling of a kind of excavator

Technical field

The present invention relates to a kind of on the excavator part employed general frock during the inclined-plane of milling different angles.

Background technology

In the manufacture process of excavator, there are some parts to need the inclined-plane of milling different angles, the size on the inclined-plane that these need be processed, width and oblique angle have nothing in common with each other.Milling inclined-plane processing at present, is at each bevelled part, is equipped with different frocks.Though these frocks are simple, a kind of processed part of every replacing must be changed frock, and the more time-consuming efficient of dismounting frock is lower, and a lot of occupations of land of frock quantity are bigger.

Summary of the invention

The purpose of this invention is to provide a kind of on the excavator part employed general frock during the inclined-plane of milling different angles.

In order to achieve the above object, technical scheme of the present invention has provided the general inclined-plane frock of milling of a kind of excavator, it is characterized in that: comprise holder, on holder, be provided with swing span, location-plate is fixed on the top of swing span, is provided with the anchor clamps that are used for fixing part to be processed on location-plate, is equipped with central shaft in holder and swing span, pendulous device drives swing span and rotates around central shaft, locatees by positioner after swing span rotate in place.

Side at described holder is provided with dial and the pointer that is used to indicate rotational angle.

Have circular-arc T-slot at the front end of swing span and the both sides of rear end, four tommyhead bolts are housed in the groove, packing ring and nut are housed on the bolt, screw four nuts and just can be locked in the desired position to swing span securely;

There are two ends that the rotating nut of rolling bearing is housed in the kidney slot of the base of described pendulous device, moveable hinge joins holder and swing span together by parts such as articulated slab, location-plate, central shafts, one end of screw rod is contained in and can only rotates in the hole of moveable hinge but relative moving axially can not be arranged, the other end of screw rod screws in the rotating nut, rotating screw bolt is by screw rod moving axially in rotating nut, the drive moveable hinge moves forward and backward, and makes swing span reach required angle position around the central shaft swing by articulated slab;

Described anchor clamps are included in a plurality of screws of arranging on the described location-plate, be positioned at second Anchor plate kit at described location-plate middle part and be positioned at first Anchor plate kit around second Anchor plate kit.

Described positioner is a nut and bolt.

Principle of the present invention is that the spiral fork drives pivoting part, adds on the required angle thereby be transformed into the workpiece machine apace, and can be suitable for the most of part that requires to mill the inclined-plane of excavator.

Advantage of the present invention is simple to operate, safety, and efficient gets a promotion.

The specific embodiment

For the present invention is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.

As shown in Figure 1 to Figure 3, the general inclined-plane frock of milling of a kind of excavator provided by the invention comprises holder 1, on holder 1, be provided with swing span 2, location-plate 3 is fixed on the top of swing span 2, on location-plate 3, be provided with the anchor clamps that are used for fixing part 20 to be processed, these anchor clamps are included in a plurality of screws of arranging on the location-plate 3, be positioned at second Anchor plate kit 9 at location-plate 3 middle parts and be positioned at second Anchor plate kit 9, first Anchor plate kit 8 on every side, in holder 1 and swing span 2, be equipped with central shaft 10, pendulous device 7 drives swing span 2 and rotates around central shaft 10, locatees by positioner after swing span 2 rotate in place.

As shown in Figure 4, positioner is nut 11 and bolt 12.

As Fig. 1 and shown in Figure 4, have circular-arc T-slot at the front end of swing span 2 and the both sides of rear end, four tommyhead bolts 12 are housed in the groove, packing ring and nut 11 are housed on the bolt 12.

In conjunction with Fig. 5 to Fig. 7, pendulous device 7 comprises base 15, the two ends of rotating nut 16 lay respectively in the base 15, rotating nut 16 connects a screw rod 19, outside screw rod 19, be with moveable hinge 18, be respectively equipped with an articulated slab 14 below reaching above the moveable hinge 18, an end of articulated slab 14 is meshed with moveable hinge 18, and the other end is hinged with holder 1 and location-plate 3 respectively.

Be with a bearing 17 respectively at the two ends of rotating nut 16.

The moveable hinge 18 that drives on it by rotary screw 19 moves, be connected with location-plate 3 with holder 1 respectively by two bearings 13 by two articulated slabs 14 again, thereby make location-plate 3 rotate the effect that reaches adjusting angle with the rotation of screw rod 19 around central shaft 10, the angle value of concrete rotation is shown on dial 4 by pointer 5.When plate 3 to be positioned goes to desired location, by bolt 12 and nut 11 swing span 2 and holder 1 are locked, thereby guarantee that machine added-time incline position is constant.Base 15 is provided with kidney slot, rotating nut 16 slides in kidney slot, kidney slot provides a correct movement locus herein, the prevention movement interference, rotating nut 16 two ends place base 15 by bearing 17 and rotate therein simultaneously, this moment, bearing 17 mainly reduced friction, and was convenient to the rotation of rotating nut 16.

During use, the workpiece that need mill the inclined-plane in the excavator is installed on the location-plate 3 of the present invention, following surface and front end block 6 are located respectively, clamp with Anchor plate kit, subsequently, manually control screw rod 19 rotations, make part to be processed be in the demand position, it is fixing with nut 11 and bolt 12, carry out machine then and add.
