Abstract
The utility model discloses a quick-change tool apron device used for a milling rotor. The quick-change tool apron device comprises a base, a tool case and a milling tool, wherein the tool case is mounted in the mounting hole of the base, and the milling tool is mounted in a hole at work end of the tool case. By arranging the tool case between the base and the tool, the tool case and the base are in tight fit installation, and relative motion therebetween is avoided, thereby ensuring that the tool case can bear strong impacts from the tool; an anti-rotation groove and an anti-rotation lug boss are formed on both the tool case and the base, so as to prevent the relative rotation therebetween; the tool case and the base are fixed through a retaining ring in axial direction, so as to prevent the tool case from dropping off; in addition, anti-corrosive grease is filled between the tool case and the base which are sealed through a sealing ring, so that the tool can be taken out and the tool case can be replaced conveniently during repairing.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates to the device that uses on a kind of pavement milling machine, is specifically related to a kind of quick change tool rest device that is used for the milling rotor.
Background technology
Pavement milling machine is one of main machine of maintenance of surface operation, the disease such as rut, carbuncle bag, be full of cracks that is used for flexible pavement is carried out maintenance work, promptly by being installed in the epitrochanterian all a plurality of cutters of milling, the road-surface milling of corrupted is cut into broken shape, so that again the road surface is repaired after removing.Be installed in the epitrochanterian many tool rest devices of milling, be made up of fixed pedestal and cutter usually, pedestal is welded on the cylindrical shell of milling rotor, and cutter is directly installed in the pedestal hole.In the cutting operation process, cutter is finished the cutting of road pavement by rotatablely moving of milling rotor.For guaranteeing the cutter head uniform wear, increase the service life, during cutter work, should be able to accomplish to cut on one side, in the pedestal installing hole, rotate around self axis.Existing tool rest device, cutter, must cut away the cutter base that lost efficacy earlier when pedestal needs to repair because of damage the serious wear of pedestal, can weld new pedestal again.Therefore, there is the shortcoming that application life is short, maintenance bothers in existing cutter base.
Summary of the invention
The purpose of this utility model provides a kind of quick change tool rest device that is used for the milling rotor, has solved the problem of existing cutter base weak point in application life, maintenance trouble.
The technical scheme that the utility model adopted is that a kind of quick change tool rest device that is used for the milling rotor comprises pedestal, in the installing hole of pedestal broach shell is installed, and the milling cutter is installed in the hole of broach shell working end.
Characteristics of the present utility model also are,
Be tight fit between broach shell wherein and the pedestal installing hole;
Be filled with anti-corrosive grease between broach shell wherein and the pedestal, and adopt the sealing ring sealing;
Pedestal installing hole one end wherein is provided with anti-rotation boss and this anti-rotation boss and matches and be provided with anti-rotation groove in the working end of broach shell;
The broach shell other end wherein is provided with back-up ring.
The beneficial effects of the utility model are, by between pedestal and cutter broach shell being set, being tight fit between broach shell and the pedestal and installing, and do not have relative motion between the two, thereby can bear the intense impact of cutter; Be processed with anti-rotation groove and anti-rotation boss on broach shell and the pedestal, prevent to produce relative rotation between the two; Axially fixing of broach shell and pedestal, prevent that broach shell from deviating from back-up ring; In addition, be marked with anti-corrosive grease between broach shell and the pedestal, and, be beneficial to during reparation and take out and change broach shell with the sealing ring sealing.
Description of drawings
Fig. 1 is the structural representation of the utility model quick change tool rest device.
Among the figure, 1. pedestal, 2. back-up ring, 3. sealing ring, 4. broach shell, 5. milling cutter.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model quick change tool rest device, as shown in Figure 1, comprise pedestal 1, broach shell 4 is installed in the installing hole of pedestal 1, adopt tight fit between the installing hole of the external surface of broach shell 4 and pedestal 1, pedestal 1 installing hole one end is provided with the anti-rotation boss, match with this anti-rotation boss and to be provided with anti-rotation groove in the working end of broach shell 4, broach shell 4 is installed on the part in pedestal 1 installing hole, be filled with anti-corrosive grease between the sidewall of its outer round surface and this installing hole, and seal by two O RunddichtringOs 3, the outside that the end that broach shell 4 passes pedestal 1 is in pedestal 1 installing hole is provided with back-up ring 2; In the hole of broach shell 4 working ends milling cutter 5 is installed.Milling cutter 5 adopts standard cutter; O RunddichtringO 3 can prevent that foreign matter from entering bonding surface between broach shell 4 and the pedestal 1, causing this bonding surface corrosion, influences the replacing of broach shell 4; Anti-rotation boss and anti-rotation groove can prevent to relatively rotate between broach shell 4 and the pedestal 1; When back-up ring 2 can prevent to dismantle milling cutter 5, broach shell 4 was deviate from pedestal 1, or broach shell 4 accidents drop in the course of the work.
The course of work of the utility model quick change tool rest device: according to the shape and size of design, process pedestal 1 and broach shell 4 respectively, after machining, install by assembling drawing, and the anti-corrosive grease of between the matching surface of broach shell 4 and pedestal 1, annotating, make required device.The pedestal 1 of this device is welded in the relevant position of milling rotor drum external surface, milling cutter 5 is installed then, the milling rotor of starting pavement milling machine, this milling rotor rotation, and then drive pedestal 1, broach shell 4 and milling cutter 5 together rotate, 5 pairs on milling cutter needs the road surface or the roadbed of maintenance to cut, make its fragmentation, pavement milling machine is removed the waste material of cutting simultaneously, then, again road surface pavement or roadbed are finished the maintenance of highway.
Pedestal in the utility model quick change tool rest device is through finite element analysis, and the result shows, its force-bearing situation is good, do not have obvious region of stress concentration, safety factor affluence; Have very strong impact resistance and mar proof, prolonged application life.
