Description

Tool sharpening machine

Affiliated technical field

The present invention relates to a kind of tool sharpening machinery, particularly a kind of can temper simultaneously many cutter with can temper the sharpening machine of inserted tool (as: Stupalox).

Background technology

In prior art, a kind of tool sharpening machine of domestic public use mainly comprises a pair of electronic bistrique, referring to Figure 11,12, this end face to electric wheel bistrique 20,21 is relative, and be the goat's horn formula and be in tilted layout, be provided with a toolframe 22 between them, the upper end of toolframe accompanies cutter 23, its lower end be provided with master plate 24 and one fixing argue 25.This toolframe is promoted slowly by the electronic bistrique 20,21 of rotation at a high speed by hydraulic cylinder 26, and toolframe 22 moves according to the sharpening curve of master plate is upper and lower again when advancing, thereby finishes the sharpening curve that provides according to the master plate sharpening to cutter.The operating efficiency of this tool sharpening machine is lower, once can only grind a cutter, and the time mill of advancing, and bistrique idle running is not ground when retreating, inefficiency not only, and also action is complicated, wayward.Moreover in the process of tempering, bistrique is rigid contact with contacting of cutter, make bistrique and cutter all be easier to damage, especially to inserted tool (as: Stupalox), bistrique can can't be finished because of damage and temper, therefore, it can only finish tempering of metal material class cutter.

Summary of the invention

The objective of the invention is shortcoming, a kind of high efficiency is provided, tempers simple, the easy control of action and can finishes the tool sharpening machine that inserted tool tempers at prior art.

For achieving the above object, solution of the present invention is as follows:

It has a framework platform, by support a rotating shaft is housed on this framework platform, and described rotating shaft links by chain drive and deceleration mechanism; A pattern dish and a folder cutterhead are housed in described rotating shaft at least, be respectively equipped with a slide unit in the both sides of described rotating shaft, described slide unit is installed on the slide rail by linear bearing, described slide rail is fixed on the framework platform by support, be provided with a pair of and the inconsistent pattern contact in the edge pattern dish in the both sides of pattern dish, this is fixed on the slide unit of each side by a support respectively the pattern contact, in the both sides of described folder cutterhead are provided with blade, the a pair of electronic bistrique that temper in the outside, should be fixed on the slide unit of each side by a support respectively electronic bistrique, on described support, be provided with the angle of pitch adjustment structure of electronic bistrique, the adjustment structure that swings and advance and retreat cutter adjustment structure; Below described framework platform, be respectively equipped with the steel wire traction mechanism of two slide units, perhaps on the slide rail of two slide units, be with respectively and promote the spring that slide unit is drawn close to rotating shaft.

The further solution of the present invention is as follows:

Be provided with two folder cutterheads in above-mentioned rotating shaft, these two folder cutterheads are installed in the two ends of rotating shaft respectively, and described pattern dish is installed in the centre of rotating shaft, and in the both sides of each folder cutterhead a pair of electronic bistrique that the blade medial and lateral are tempered are set respectively.

Above-mentioned folder cutterhead is made of basal disc and a plurality of clamp clip that is fixed on the basal disc, and described a plurality of clamp clips all are fan shape, and can piece together becoming and the identical circle of basal disc size, is provided with folder cutter groove between basal disc and clamp clip; Described pattern dish also is made of basal disc and a plurality of pattern sheet that is fixed on the basal disc, and described a plurality of pattern sheets all are fan shape, and can piece together becoming a circle more bigger than basal disc, is provided with the sharpening curve on the external arc line segment of each fan-shaped pattern sheet.

Be provided with an autofeed mechanism on the advance and retreat cutter adjustment structure of above-mentioned support, this mechanism comprises a stepper motor, and this stepper motor changes transmission mechanism by a cover tooth and the feed adjustment structure links.

By above-mentioned solution as can be seen, the present invention makes toolframe into discoid, like this, all can press from both sides cutter along a week of disk, and the rotation by disk, bistrique can temper successively to a plurality of cutters on the disk, action does not have idle work continuously, has not only improved operating efficiency greatly, and temper evenly, action is simple, control easily; Simultaneously, the present invention is improved to Elastic Contact with bistrique with contacting of cutter, realized that flexibility tempers, this flexibility is tempered and can be made cutter and bistrique equal easy damaged not in the process of tempering, be particularly suitable for tempering inserted tool (as: Stupalox), thereby solved the difficult problem that existing sharpening machine is difficult to temper inserted tool.
