Abstract

The utility model relates to a tapered-hole processing device, which belongs to the field of the mechanical processing device. The tapered-hole processing device consists of a main shaft box, an exchange gear box, a feeding box, a chute box, a cutter holder, an end bracket, an unthreaded rod, a screw rod, a lathe bed, legs and a cooling device, and is characterized in that: two independent holes are arranged on the head part of the cutter holder, the two holes are coaxial to each other and are provided with a locking device, and each hole is provided with a cutter. A tool bit of the cutter is rotated, so a pointer points a scale of an angle scale, a rotating angle can be displayed, the angle of the tool bit and a cutter rod can be locked by a locking disc so as to be maintained constant, and an fixed angle is formed between the tool bit and the cutter rod. Due to the tapered-hole processing device, a hole with gradient can be processed, i.e. a reversed tapered hole; and when the gradient is changed, the angle of the tool bit and the cutter rod can be adjusted so as to satisfy the processing requirement.

Description

A kind of taper hole process equipment

Technical field

The utility model and machine cut process equipment, a kind of specifically taper hole process equipment.

Background technology

The main building block of engine lathe has: main spindle box, change gear box, feed box, slip crate, knife rest, tailstock, feed rod, leading screw, lathe bed, cabinet base and cooling device.Main spindle box: claim headstock again, its main task is to make main shaft obtain required positive and negative two kinds of different rotating speeds that turn to a series of gear of process that rotatablely moves that main motor transmits, and main spindle box is told part power feed box is passed in motion simultaneously.The medium main shaft of main spindle box is the vital part of lathe.The stationarity that main shaft turns round on bearing directly influences the crudy of workpiece, in case the running accuracy of main shaft reduces, then the use value of lathe will reduce.Lathe tool is the important tool of machine cut processing, and the lathe tool that generally uses is made of knife bar and cutter head at present, and cutter head is packed in the front portion of lathe tool, is the part that lathe tool cuts, and the cutting part of cutter head also is the sub-fraction of cutter head.According to the principle of machined into, general lathe tool can only be processed straight hole, can't finish the processing in the hole that has the gradient.

Summary of the invention

In view of the defective that prior art exists, the purpose of this utility model is to provide a kind of taper hole process equipment, can the acclive circular hole of processing belt.

For achieving the above object, the technical solution that the utility model adopted mainly is to be made of main spindle box, change gear box, feed box, slip crate, knife rest, tailstock, feed rod, leading screw, lathe bed, cabinet base and cooling device, the knife rest head has two independently holes, two holes are coaxial, have locking device, each hole installs one cutter.Described cutter by cutter head, knife bar constitute, cutter head (5) and tool rest weld together, tool rest is connected the knife bar upper end by rotating shaft, locking plate is arranged in the rotating shaft, it is characterized in that: fixed vertical is in the downward pointer of cutter head on the tool rest, knife bar posts angle scale and is positioned at the pointer back, when knife bar is vertical with cutter head, middle 0 degree of pointed angle scale.Angle scale is semicircle, is the boundary with middle 0 degree, and upper left and upper right scale is shown as 45 and spends, between equivalent distribution scale value.Rotary cutter on the scale of pointed angle scale, shows the anglec of rotation, and it is constant that locking plate pins the fixed angle of cutter head and knife bar, and cutter head and knife bar form fixed angle.

After adopting such scheme, compared with prior art have following beneficial effect: the utility model is installed in processing work on the knife rest of lathe, can process the hole that has certain slope, i.e. rounding platform pass, when changing the gradient, the angle of adjusting cutter head and knife bar can satisfy processing request.

Description of drawings

Fig. 1 is a kind of structural representation of taper hole process equipment.

Fig. 2 is a kind of side view of taper hole process equipment.

Fig. 3 is a kind of cutter scheme of installation of taper hole process equipment.

Among the figure: locking plate 1, angle scale 2, pointer 3, knife bar 4, cutter head 5, rotating shaft 6, tool rest 7, main spindle box 8, knife rest 9, cutter 10, locking device 11, tailstock 12.

The specific embodiment

For understanding a kind of taper hole process equipment in depth, be described as follows in conjunction with Fig. 1, Fig. 2:

Constitute by main spindle box 8, change gear box, feed box, slip crate, knife rest 9, tailstock 12, feed rod, leading screw, lathe bed, cabinet base and cooling device, it is characterized in that: knife rest 9 heads have two independently holes, two holes are coaxial, have locking device 11, and each hole installs one cutter 10.Cutter head 5, knife bar 4 constitute, and cutter head 5 and tool rest 7 weld together, and tool rest 7 is connected knife bar 4 upper ends by rotating shaft 6, and locking plate 1 is arranged in the rotating shaft 6.Fixed vertical is in the downward pointer 3 of cutter head 5 on the cutter head tool rest 7, and knife bar 4 posts angle scale 2 and is positioned at pointer 3 back, when knife bar 4 and cutter head 5 are vertical, and middle 0 degree of pointer 3 orientation angle dishes 2.Angle scale 2 is semicircle, is the boundary with middle 0 degree, and upper left and upper right scale is shown as 45 and spends, between equivalent distribution scale value.Before the processing work, rotary cutter 5 on the scale of pointer 3 orientation angle dishes 2, shows the anglec of rotation, and it is constant that locking plate 1 pins the fixed angle of cutter head and knife bar 4, and cutter head 5 and knife bar 4 form fixed angle.To adjust being installed on the lathe of lathe tool of angle, knife bar 4 is fixed on the knife rest of lathe, and start is carried out grinding to workpiece.The angle that shows on the dial, just the angle of cutter head 5 and knife bar 4 formation adds man-hour exactly, and workpiece forms the angle of the circular hole gradient.
