Description

New-type key duplicating machine

Technical field

The utility model relates to a kind of mechanical field, particularly relates to a kind of high accuracy key duplicating machine of new-type portraitlandscape feed.

Background technology

The knife rest shape of the key duplicating machine of people's use now mostly is a square greatly, the square knife rest is provided with and the mould pin, the anchor clamps of milling cutter position correspondence, its tool axis is positioned on the angle of square, as shown in Figure 1, be positioned at the lower right corner of knife rest, yet, because the height difference of key bit, when knife rest the is vertical and point of contact of milling cutter just in time is the minimum point of key bit, in copy key, need knife rest to swing around tool axis like this, can finish the process of preparation key according to the shape of the key bit of original key, yet because milling cutter is circular, and key has certain thickness, thereby the swing of knife rest will inevitably cause that the key flank of tooth forms an inclined-plane, as shown in Figure 2, the Key structure and the original key that cause duplicating have very big difference, and error is big.

The utility model content

The purpose of this utility model is the big shortcoming of the vertical Straight Line and Arc swing feed frame copy key error of existing key duplicating machine, and a kind of high accuracy key duplicating machine of new-type portraitlandscape feed is provided.

The technical solution of the utility model is: a kind of new-type key duplicating machine, comprise base, be arranged at the mould pin on the base, milling cutter, knife rest and the knife rest cardan shaft that joins with drive unit, wherein, knife rest is provided with and the mould pin, the corresponding anchor clamps in milling cutter position, described knife rest is divided into horizontal knife rest and longitudinal tool rest, longitudinal tool rest is set on the longitudinal axis that is installed on the base vertical with the milling cutter knife face, is fixed with cross slide way on the longitudinal tool rest, and laterally knife rest is installed on the cross slide way, wherein, anchor clamps are installed on the horizontal knife rest, laterally are provided with between knife rest and the cross slide way and laterally feed extension spring automatically, and the knife rest cardan shaft advances longitudinal tool rest.

Preferably: the both sides of longitudinal axis are equipped with the parallel adjustment bolt of longitudinal tool rest between described base and the longitudinal tool rest.

Preferably: cross slide way is installed between described horizontal knife rest and the cross slide way adjusts bolt.

Preferably: knife rest, milling cutter gap adjustment bolt are installed between described horizontal knife rest and the cross slide way.

The beneficial effects of the utility model are: the utility model is by changing the structure of key duplicating machine knife rest, make in the process of copy key, no matter be the height point of key bit or the position, same point of contact that low spot all is positioned at milling cutter, it is the position, point of contact of anchor clamps and milling cutter, thereby the structure of the key bit of duplicated key and original key is identical, the accuracy of repetition height, the key flank of tooth that existing key duplicating machine duplicates can not occur is the situation on inclined-plane.In addition, parallel longitudinal is installed between base and the longitudinal tool rest adjusts bolt, be used to adjust the horizontal level of longitudinal tool rest, error can be low to moderate 0.02mm, and cross slide way laterally is installed between knife rest and the cross slide way adjusts bolt, can the adjusting play be 0.01mm, knife rest, milling cutter adjustment bolt laterally are installed between knife rest and the cross slide way, can adjust the gap between milling cutter and the anchor clamps, be generally 0.2mm, improve the precision of key duplicating machine so greatly.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model:

As Fig. 3 to a kind of new-type key duplicating machine shown in Figure 4, comprise base 1, be arranged at the mould pin 2 on the base 1, milling cutter 3, knife rest and the knife rest cardan shaft 4 that joins with drive unit 12, wherein, knife rest is provided with and mould pin 2, the corresponding anchor clamps 5 in milling cutter 3 positions, described knife rest is divided into horizontal knife rest 6 and longitudinal tool rest 7, longitudinal tool rest 7 is set on the longitudinal axis 8 that is installed on the base 1 vertical with milling cutter 3 knife faces, be fixed with perpendicular cross slide way 9 on the longitudinal tool rest 7, laterally knife rest 6 is installed on the cross slide way 9, wherein, anchor clamps 5 are installed on the horizontal knife rest 6, laterally are provided with between knife rest 6 and the cross slide way 9 and laterally feed extension spring 10 automatically, all the time give the power of horizontal knife rest 6 to milling cutter 3 directions, knife rest cardan shaft 4 advances longitudinal tool rest 7.The both sides of longitudinal axis 8 are equipped with the parallel adjustment bolt 11 of longitudinal tool rest between base 1 and the longitudinal tool rest 7, in order to regulate the horizontal level of longitudinal tool rest 7.Cross slide way laterally is installed between knife rest 6 and the cross slide way 9 adjusts bolt 18.Knife rest, milling cutter gap adjustment bolt 13 laterally are installed between knife rest 6 and the cross slide way 9, are used to adjust the gap between milling cutter 3 and the anchor clamps 5.

The structure diagram of existing key duplicating machine as shown in Figure 1, its tool axis 15 is arranged at the lower right corner of knife rest 16, in the time of copy key, distance between the key bit spikes/low-points is between 0-5mm, the B point mills out is the low spot of key, distance between the AB is 5mm, thereby, when milling cutter mills the high point of key, need knife rest 16 to rotate, thereby this moment, the position on milling cutter was the C point around tool axis 15, and the shape of the key flank of tooth 17 that mills out at this point as shown in Figure 2, be an arcwall face, be not inconsistent with the original key shape, thereby inaccuracy.

During work, after regulating various bolts and reaching necessary requirement, original key and the key that needs preparation are all folded up on anchor clamps 5, connect power supply, drive unit 12 drives 4 motions of knife rest cardan shaft, knife rest cardan shaft 4 promotes longitudinal tool rest 7 axle 8 motions longitudinally, simultaneously, under the effect of mould pin 2 and original key, laterally knife rest 6 slides along cross slide way 9, thereby the key that needs duplicate is duplicated successfully under the effect of milling cutter, in addition, the utility model is provided with manual rocking handle 14, can be used for the manual operation key duplicating machine.
