Abstract

The utility model discloses a cutter disassembling machine for vertical milling machines, which is used for disassembling a cutter and a cutter handle which are used by a numerical control milling machine and a normal milling machine. The cutter disassembling machine for vertical milling machines solves the technical problem of the manual beating mode and the disassembling mode that the labor intensity is large, labor and time are wasted, the disassembling mode is unsafe and the cutter is easy to damage. The cutter disassembling machine comprises a box body, an upper supporting seat, a lower supporting seat, a cylinder, a guide rail, a cutter slide block, a support column, a guide sleeve, a guide post, a gas-liquid force increasing cylinder, a slide block, a pressing block, a cylinder without rods, and a protective door. The utility model has the advantages that mechanical cutter disassembling is realized, the labor intensity is lightened, and cutter disassembling is rapid, and the utility model is safe and labor-saving. The cutter disassembling machine for vertical milling machines is widely used for disassembling the cutter and the cutter handle which are used by a numerical control milling machine machining center and a normal vertical-milling machine.

Description

The special-purpose cutter disassembling machine of end mill

Technical field: the invention is used for the dismounting between CNC milling machine and employed cutter of plain-milling machine and the handle of a knife.

Background technology: the employed cutter of end mill is that Morse's taper connects with handle of a knife, stiction by cutter and handle of a knife contact area transmits moment of torsion, because cutter cutting force in machining is bigger, need the cooperation tapering face of cutter and handle of a knife bigger, under the torsional interaction that cutting force produces, make easily between cutter and the handle of a knife and produce pinning phenomenon, when tool changing, often cutter need be pulled down from handle of a knife, but generation because of pinning phenomenon, be difficult to pull down between cutter and the handle of a knife, all be manually just can unload bottom tool with the blind rivet on the sledgehammer knocking cutter in the past, therefore unloading cutter wastes time and energy., and metal fragment takes place easily splash and hurt sb.'s feelings and damage the cutter phenomenon, at present, the design of part complexity of Digit Control Machine Tool processing, the tool category that needs is various, and quantity is big, and part of every processing just needs to change multiple cutter, therefore the frequent cutter of changing, the dismounting cutter has increased a large amount of unloading the cutter time.

Summary of the invention: the purpose of the invention provides and a kind ofly can alleviate the labour intensity that unloads cutter, and unloads cutter fast, does not damage the special-purpose cutter disassembling machine of end mill of cutter; The purpose of the invention is achieved through the following technical solutions: the special-purpose cutter disassembling machine of end mill is characterized in that being made of casing, undersetting, upper bracket, cylinder, guide rail, cutter slide block, support column, guide pin bushing, guide pillar, gas-liquid power-increasing cylinder, slide block; Undersetting is installed in the casing, the undersetting upper mounting rail, mounting cutter slide block on the guide rail, cylinder is fixedly mounted on the casing, the piston rod of cylinder is connected with the cutter slide block, four support columns are installed on the undersetting, and bearing is installed in the support column upper end, and gas-liquid power-increasing cylinder is installed on the upper bracket, two guide pin bushings are installed on the upper bracket, guide pillar is installed in the guide pin bushing, and slide block is installed in the lower end of guide pillar, and the piston rod of gas-liquid power-increasing cylinder is connected with slide block.

The special-purpose cutter disassembling machine of end mill is installed protective door and Rodless cylinder on casing, the piston of protective door and Rodless cylinder is connected.

The special-purpose cutter disassembling machine of end mill is installed briquetting on slide block.

The advantage of the invention: because the special-purpose cutter disassembling machine of end mill has been arranged, the dismounting cutter carries out on cutter disassembling machine, or else with manually beating, has alleviated the labour intensity that unloads cutter, and is laborsaving; When unloading cutter cutter and handle of a knife assembled state are placed on the cutter slide block, the action of gas-liquid power-increasing cylinder drives slide block and moves down, and the briquetting of installing on the slide block is pressed in the blind rivet on the cutter, and moment is pulled down cutter, realizes unloading fast cutter; Owing to need not beat, not damage cutter; Because gas-liquid power-increasing cylinder can realize that briquetting contacts the back and increases pressure with the cutter blind rivet, is implemented under the static pressure and unloads cutter, does not produce strike note; Move because Rodless cylinder drive protective door has been installed, after protective door is closed, could implement to unload the cutter action, realize the closed cutter that unloads, avoid producing the accident that maloperation produces; Adopt the hardness ratio slide block hardness height of briquetting, directly contact, increased the wearability of working portion, after wearing and tearing, also be convenient to change with the cutter blind rivet by briquetting.Because upper and lower mobile guide pin bushing, the guide pillar structure of having adopted of slide block reduces the generation of side force; Owing to adopted gas-liquid power-increasing cylinder, cancel simple hydraulic power unit, reduced the volume of the special-purpose cutter disassembling machine of end mill.

Description of drawings:

Fig. 2 be among Fig. 1 A to view

The specific embodiment: the special-purpose cutter disassembling machine of end mill is by casing 1, undersetting 2, upper bracket 9, cylinder 13, guide rail 12, cutter slide block 14, support column 4, guide pin bushing 6, guide pillar 7, gas-liquid power-increasing cylinder 8, slide block 5, Rodless cylinder 10, protective door 3, briquetting 11 constitutes, undersetting 2 is installed on the casing 1, undersetting 2 upper mounting rails 12, mounting cutter slide block 14 on the guide rail 12, cylinder 13 is fixedly mounted on the casing 1, the piston rod of cylinder 13 is connected with cutter slide block 14, four support columns 4 are installed on the undersetting 2, bearing 9 is installed in support column 4 upper ends, gas-liquid power-increasing cylinder 8 is installed on the upper bracket, two guide pin bushings 6 are installed on the upper bracket 9, guide pillar 7 is installed in the guide pin bushing 6, slide block 5 is installed in the lower end of guide pillar 7, briquetting 11 is installed on the slide block 5, the piston rod of gas-liquid power-increasing cylinder 8 is connected with slide block 5, Rodless cylinder 10, protective door 3 is installed on the casing 1, and the piston of Rodless cylinder 10 is connected with protective door 3.Its course of work is that protective door is in open mode, the cutter slide block is in the state of stretching out and treats work, when cutter and handle of a knife assembled state state promptly to be torn open are placed on the cutter slide block, press the special-purpose cutter disassembling machine work of knob end mill and start, its program is that cutter slide block band and waited to unload cutter with handle of a knife is withdrawn into position to be torn open, and Rodless cylinder moves, the drive protective door moves, protective door is in closed condition, realizes sealing and unloads cutter, avoids maloperation to take place, when protective door is closed, gas-liquid power-increasing cylinder drives slide block and moves down fast, when briquetting with after blind rivet on the cutter contacts, rapid supercharging, the realization static pressure is finished the cutter work of unloading, do not produce strike note, then, gas-liquid power-increasing cylinder resets, protective door is opened, the cutter slide block stretches out, and takes off the cutter of having pulled down, finishes the cutter work of unloading.
