Abstract

The utility model relates to a movable high-speed perforation machine, which comprises a base, an upright post, a secondary travel component, a rotating seat, a supporting arm and a main shaft head component. A main shaft is driven by a rotating motor to rotate, and the main shaft head component performs servo feeding by a servo motor through ball screw lead driving. The main shaft is provided with a slim electrode of 0.3 to 3mm to discharge workpieces and process small deep holes. The main shaft head component can rotate left and right around the rotating seat of the supporting arm and is fixed by a radial lock nut. The supporting arm can perform up-down movement on the secondary travel component, rotate around the secondary travel component and is fixed by a lock nut. The secondary travel component is driven by a hand wheel to perform servo feeding through ball screw lead driving, and performs up-down movement along the upright post. The upright post is connected with the base; and after being connected with a magnet or an electromagnet in the base, the upright post can be adsorbed on the workpieces, so the small deep holes of the workpieces with a more complicated surface or any space can be operated for an electrical discharge machining. Particularly, when the workpieces are larger and cannot be clamped on a worktable of a common small hole machine, the movable high-speed perforation machine is easier to work, and ensures the processing precision and the processing efficiency.

Description

Portable high speed punch

Technical field

The utility model relates to the electrical process machine field, be mainly used in the dark aperture on the various conductive material workpieces such as processing stainless steel, hardened steel, carbide alloy, copper, aluminium, also can be used for removing the drill bit that fractures in workpiece, screw tap etc., and can defective work piece or screw thread.

Background technology

In machining, because hardness such as stainless steel, hardened steel, hard alloy steel are higher, the dark aperture of difficult processing; Perhaps before carrying out Wire-cut Electrical Discharge Machining, need to process thinner wire hole; Perhaps need on the inclined-plane of workpiece, curved surface, process aperture; Perhaps screw tap machining screw, bit bore in the process such as reamer fraising, fractures cutter in workpiece.Existing method one is to process with the mechanical grinding lathe, and because of machining hole is little, employed abrasive grinding wheel is less, and grinding wheel spindle is thin, under the effect of machine cut power, very easily produces distortion, vibration, is difficult to guarantee the machining accuracy and the surface roughness of workpiece.Another kind method is to adopt the electric spark small hole machining tool, in the aperture process, tool-electrode loses aperture by discharging, and does not have mechanical force because of tool-electrode does not directly contact with workpiece, so can not produce mechanically deform, precision and surface roughness can be guaranteed.

The design has adopted on the process principle basis of galvano-cautery, and the profile and the immanent structure of lathe improved, and makes it adapt to demand in the above-mentioned real work, improves the novel aperture machine that becomes a kind of portable high speed.

Summary of the invention

The purpose of this utility model is the aperture machine that the aperture machine that the profile of the band cross table of routine is bigger improves becomes a portable compact conformation, and its structure is light and handy, and is easy to use, can adapt to the processing request of the dark aperture on any locus.The purpose of this utility model is achieved in that portable high speed punch, and it comprises base, column, secondary stroke assembly, rotating seat, support arm, main tapping assembly etc.Main shaft drives rotation by electric rotating machine, and clamping has the processing of discharging of electrode pair workpiece on the main shaft.Main shaft moves up and down on leading screw under the drive of servomotor, has formed the main tapping assembly.The main tapping assembly can be on support arm the rotating seat left rotation and right rotation, with locking nut fixed position radially.Support arm can move up and down on the secondary stroke assembly, and around the rotation of secondary stroke assembly, uses the locking nut fixed position.The secondary stroke assembly is driven by handwheel and does servo feed by the ball-screw transmission, moves up and down along column.Column is connected with base, behind the magnet or electromagnet in the connection base, just can be adsorbed on the workpiece.Like this can be to the workpiece of more complicated face or the processing of discharging of the dark aperture on the space arbitrarily.

Particularly can't clamping when workpiece is big on the workbench of common aperture machine, it is much easier to adopt this kind packaged type punch to work together, and machining accuracy and working (machining) efficiency are all secure.

The utility model is owing to adopt said structure, and portable high speed punch can be placed on position suitable on the workpiece processing of discharging very easily.

Description of drawings

Accompanying drawing 1 is the operation chart of the portable high speed punch of the utility model.

Accompanying drawing 2 is schematic diagrames that the portable high speed punch of the utility model is processed dark aperture.

The specific embodiment

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing, thus make the technical problems to be solved in the utility model, feature and the technique effect that reached more cheer and bright.

As shown in Figure 1, portable high speed punch is made up of base 15, column 12, secondary stroke assembly 2, rotating seat 10, support arm 7, main tapping assembly 4.Main shaft 6 drives rotation by electric rotating machine 5, and clamping has the processing of discharging of 13 pairs of workpiece of electrode on the main shaft.Main shaft 6 is moving up and down on leading screw 11 under the drive of servomotor 3, has formed main tapping assembly 4.Main tapping assembly 4 can be around 10 left rotation and right rotation of the rotating seat on the support arm 7, with radially tightening nut 9 fixed positions.Support arm 7 can move up and down on secondary stroke assembly 2, and around 2 rotations of secondary stroke assembly, with locking nut 8 fixed positions.Secondary stroke assembly 2 is driven by handwheel 1 and does servo feed by the ball-screw transmission, moves up and down along column 12.Column 12 is connected with base 15, behind the magnet or electromagnet in the connection base, just can be adsorbed on the workpiece.Like this can be to the workpiece of more complicated face or the processing of discharging of the dark aperture on the space arbitrarily.

As shown in Figure 2, be the schematic diagram that the portable high speed punch of the utility model is processed dark aperture.When φ 0.5 electrode 13 clampings to rotating shaft 16, rotate by servomotor driven rotary axle 16 by main shaft 6, the scribe point that aligns workpiece 17 is passed guider 14 processing of discharging vertically downward.When needs processing aperture is dark, can select to use secondary stroke assembly 2, finish processing in order to the stroke that adds large electrode.

Though the utility model discloses with a specific embodiment; but it is not in order to limit the utility model; any those skilled in the art; under the prerequisite that does not break away from design of the present utility model and scope; also can make various variations and modification, therefore protection domain of the present utility model is as the criterion with the scope that claim was defined.
