Abstract
The invention provides a slide block line cutting clamp which comprises a base plate and a spindle. A pin shaft is arranged on the base plate, the spindle is sleeved on the pin shaft and is of a stage-type cylinder structure, the peripheral surface of the stage-type cylinder structure comprises a small-diameter excircle of a front end and a large-diameter excircle of a bottom end, the small-diameter excircle of the front end is provided with a thread, a cover plate is sleeved on the small-diameter excircle, and the thread of the small-diameter excircle is screwed with a nut; and a straight hole is formed on the base plate, the spindle opposite to the straight hole is provided with a threaded hole, and a stud is spirally connected with the threaded hole of the spindle through the straight hole of the base plate. The spindle is used for locating a workpiece by the slide block line cutting clamp disclosed by the invention, the cover plate presses tightly the workpiece by virtue of the nut, and once line passes through any one of an upper hole and a lower hole. After the line passes through the upper hole or the lower hole by virtue of the slide block line cutting clamp, the line does not need to be repeatedly fed, thus the problem of influence on surface roughness due to surface discharge caused by poor contact of the workpieces in the prior art is prevented.
Description
Technical field
The present invention relates to a kind of slide block linear cutting clamp.
Background technology
In the slide block manufacture process, the Technology for Heating Processing of vacuum hardening, hardness behind the inside and outside circle correct grinding, on entity, are got round relatively centrosymmetric eight workpiece at the HRC56-58 degree.Cut by the commonsense method line and to be difficult for reaching symmetry and be prone to produce the surface-discharge surface of the work of burning; And wear silk for every; In sum, the existence meeting of these problems directly influences the quality of slide block.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of slide block linear cutting clamp is provided.
The object of the invention is realized through following technical scheme:
The slide block linear cutting clamp comprises base plate and mandrel, and characteristics are: said base plate is provided with bearing pin; Suit mandrel on the bearing pin; Mandrel is the step column structure, and the outer edge surface of step column structure comprises the minor diameter cylindrical of front end and the major diameter cylindrical of bottom, and the minor diameter cylindrical of front end is provided with screw thread; Be nested with cover plate on the minor diameter cylindrical, screw thread spins with nut mutually on the minor diameter cylindrical.
Further, above-mentioned slide block linear cutting clamp wherein, has straight hole on the said base plate, has screwed hole on the mandrel relative with straight hole, and the straight hole that double-screw bolt passes on the base plate spins with screwed hole on the mandrel mutually.
The substantive distinguishing features of technical scheme of the present invention is mainly reflected in progressive:
The present invention designs uniqueness, utilizes these anchor clamps to locate workpiece with mandrel, makes the cover plate workpiece pressing by nut, once wears silk in any hole up and down.Pass or down behind the hole, need not repeat to wear silk through this anchor clamps silk, avoided that workpiece contact in the past is bad to be caused surface-discharge and influence surface roughness.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: organigram of the present invention.
The specific embodiment
As shown in Figure 1, the slide block linear cutting clamp comprises base plate 1 and mandrel 2; Base plate 1 is provided with bearing pin 5, suit mandrel 2 on the bearing pin 5, and mandrel 2 is the step column structure; The outer edge surface of step column structure comprises the minor diameter cylindrical of front end and the major diameter cylindrical of bottom; The minor diameter cylindrical of front end is provided with screw thread, is nested with cover plate 3 on the minor diameter cylindrical, and screw thread spins with nut 4 mutually on the minor diameter cylindrical.In addition, have straight hole on the base plate 1, have screwed hole on the mandrel relative with straight hole, the straight hole that double-screw bolt passes on the base plate spins with screwed hole on the mandrel mutually.
Base plate 1 edge guarantees perpendicularity 0.02 ㎜, with each hole of digital control processing, cuts circuit with Numerical Control Wire Cutting.Mandrel 2 cylindricals cooperate with the slide block internal clearance, and base plate 1 is located through bearing pin 5 with mandrel 2, is fixed by double-screw bolt; Cover plate 3 is through nut 4 workpiece pressings.
During concrete the application, first centering fixture datum is inserted in workpiece on the anchor clamps mandrel 2 at 0.02 ㎜, makes cover plate 3 workpiece pressings by nut 4, and silk is penetrated anchor clamps cutting starter hole, and the follow procedure cutting is also adjusted electrical quantity.
Utilize these anchor clamps with mandrel 2 location workpiece, cover plate 3 workpiece pressings are once worn silk in any hole up and down.Pass or down behind the hole, need not repeat to wear silk through this anchor clamps silk, avoided that workpiece contact in the past is bad to be caused surface-discharge and influence surface roughness.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. the slide block linear cutting clamp comprises base plate and mandrel, it is characterized in that: said base plate is provided with bearing pin; Suit mandrel on the bearing pin; Mandrel is the step column structure, and the outer edge surface of step column structure comprises the minor diameter cylindrical of front end and the major diameter cylindrical of bottom, and the minor diameter cylindrical of front end is provided with screw thread; Be nested with cover plate on the minor diameter cylindrical, screw thread spins with nut mutually on the minor diameter cylindrical.
2. slide block linear cutting clamp according to claim 1 is characterized in that: have straight hole on the said base plate, have screwed hole on the mandrel relative with straight hole, the straight hole that double-screw bolt passes on the base plate spins with screwed hole on the mandrel mutually.
