Description

The glass wafer cutting machine

The utility model belongs to the cutting tool technical field, particularly forms the machinery of a series of disjoint circumference cutting vestiges on glass and similar sheet material.

Circular glass sheets such as Watch glass generally are earlier glass plate to be divided into the suitable glass bar of width, cut out circumference cutting trace then on glass bar, and row separates again, and the acquisition blank.Existing hand-powered cutter is to assemble connecting axle on frame, and the upper/lower terminal of connecting axle is connected with driving wheel and cutting tool, between frame and driving wheel spring is housed.This hand-powered cutter is being formed by glass plate in the process of little glass wafer, need earlier glass plate to be divided into the suitable glass bar of width, locate one by one with staff again and, press down driving wheel simultaneously and make rotation, order about cutter and on glass bar, do the circumference cutting by deciding glass bar.This operation labour intensity is big, work efficiency is low, leftover pieces are more and the waster rate is higher.

The purpose of this utility model provides a kind of improved glass wafer cutting machine, and it can also change to standard the cutting position of cutter on glass plate by fastening glass panels easily.

The technical solution of the utility model is: a workbench that is communicated with negative pressure source is set, and the longitudinal rail and the cross slide way of the translation above workbench of guiding frame, positioner can be located mutually and can conveniently adjust its allocation frame and cross slide way, and vertically step device makes crossbeam together with the cross slide way quantitative stepping of guide rail longitudinally.

This improved glass wafer cutting machine, glass plate to be processed keeps flat to be opened negative pressure source behind the workbench and can obtain to fix, cut every row's circumference and only need adjust and fix frame position cross slide way, vertically step device can be realized the longitudinal basis weight stepping of cutting position, this has just improved work efficiency and product percent of pass, has reduced labour intensity.

The novel further improvement of this reality is vertically to add one and half step pitch driving and reversing mechanisms on the step device basis, to realize vertical half step pitch advance and retreat of cutting position, in order to improve the utilization rate of material.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Describe CONSTRUCTED SPECIFICATION of the present utility model and working condition in detail below in conjunction with accompanying drawing:

Illustrated in figures 1 and 2 and glass wafer cutting machine is to go up assembling connecting axle (2) in frame (1), driving wheel (3) is equipped with in the upper end of connecting axle (2), cutting tool (4) is equipped with in the lower end, and spring (31) is supporting driving wheel (3), connecting axle (2) and cutter (4) and making to fall.Glass plate to be cut (64) lies on the workbench (6), and suitably distributing on the work top aperture and negative pressure source (5) are connected; Longitudinal rail (7) is set on the workbench (6), crossbeam (80) falls to being placed on the longitudinal rail (7) together with cross slide way (8) and along the location orifice plate (9) with position, some holes that cross slide way (8) is arranged, frame (1) falls to being placed on the cross slide way (8), with alignment pin (10) run through locating hole (11) and the location orifice plate (9) can realize the located lateral of frame (1) and the change of lateral attitude; With reverse stiff spring (89) longitudinally guide rail draw crossbeam (80) to the right, intermittently rotate traction handwheel (88) by wire wheel axis (87), line take turns (84), steel wire (83) draws crossbeam (80) left; Ratchet (85), ratchet (86) and reverse stiff spring (89) guarantee that line wheel (84) each corner is the pairing angle of an integer ratchet.

Earlier glass plate (64) is lain on the workbench (6) during work, open negative pressure source (5) fastening glass panels (64); Throwing off ratchet (86) makes ratchet (85) together with wire wheel axis (87), line wheel (84) freely turns round, crossbeam (80) moves on to the right side of Fig. 1, make ratchet (86) cooperate ratchet (85) again, Fig. 2 that alignment pin (10) runs through locating hole (11) and location orifice plate (9) shows position, hole, the leftmost side, press down driving wheel (3) and make rotation, cutter (4) is finished glass plate (64) cutting of A circumference as shown in Figure 5, rotating traction handwheel (88) makes ratchet (85) move a tooth position to ratchet (86), steel wire (83) traction crossbeam (80) and above mechanism thereof the step pitch that moves to left, press down driving wheel (3) and make rotation, promptly finish the cutting of B circumference shown in Figure 5, repeat above-mentioned action, finish until C circumference cutting shown in Figure 5; Throw off ratchet (86) again and make crossbeam (80) move on to the right side of Fig. 1 once more, make ratchet (86) cooperate ratchet (85) then, and frame (1) is carried out located lateral again, to finish the cutting of D circumference shown in Figure 5.And so forth, can obtain cutting effect shown in Figure 5.

The line wheel (84) of replacing different-diameter and the location orifice plate (9) of different adjacent holes distances promptly can be used for cutting the glass wafer of different-diameter.

Being equal to ratchet (18) and (19) half sour jujube of staggering mutually with two as shown in Figure 3 is installed on the wire wheel axis (87) apart from phase place, or it is ratchet (18), (19) is affixed mutually and become a double rows of teeth ratchet, ratchet (85) with alternate figures 1, ratchet (86) can same respectively ratchet (18) or ratchet (19) match, form half step pitch driving and reversing mechanism.During work, the cutting that alternate selection ratchet (18) and ratchet (19) the work ratchet of work are finished row's circumference can realize cutting effect shown in Figure 6, reaches stock utilization to greatest extent.

Obviously, the utility model also can be used for cutting out the sequin of other material.

With Fig. 1 as Figure of abstract.
