Abstract

The invention relates to a transmission gap regulating mechanism for a gantry numerical control cutting machine, which is specifically applied to a mechanism moving longitudinally in a reciprocating way in numerical control cutting equipment and belongs to the technical field of cutting equipment. The transmission gap regulating mechanism comprises a permanent seat which is connected to a frame through a first bolt, wherein the permanent seat is rotationally connected with a speed reducer base through a revolving shaft; a speed reducer is fixed on the speed reducer base; a gear is arranged at the output end of the speed reducer; the front end of the gear is meshed with a rack; the speed reducer base is connected with the gear through a bearing; a limiting bracket is connected to the permanent seat through a third bolt; a through hole is formed in the limiting bracket; a limiting bolt passes through the through hole; the front end of the limiting bolt is in threaded connection with the side face of the speed reducer base; the back end of the limiting bolt is connected with a gasket; and a spring is arranged between the gasket and the limiting bracket. Due to the adoption of the transmission gap regulating mechanism, the processing requirement of the frame is lowered, the phenomenon of fracture of an expensive output shaft of a speed reduction box is reduced, the manufacturing cost is lowered, and the product quality is improved.

Description

Transmission gap adjusting mechanism of gantry numerical control cutting machine
Technical field
The present invention relates to a kind of transmission gap adjusting mechanism of gantry numerical control cutting machine, be applied to specifically vertically do back and forth movement mechanism in numerical control cutting equipment, belong to the cutting equipment technical field.
Background technique
At present, the transmission gap adjusting mechanism that uses in numerical control cutting equipment is mounted in the frame intermediate portion, transfers the gap space little.For ease of installing, the open design form need be made in frame this position, can have influence on the rigidity of frame, and installation position processed complex in frame, and the manufacturing cycle is longer.Add difficult assurance of precision in man-hour, need carry out the adjustment of gear engagement when equipment is installed.Rack and pinion engagement is bad, and the phenomenon of gear wear easily appears in equipment in running, and then causes maintenance frequently, corresponding raising manufacture cost.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of structure is ingenious, easy to adjust, assembling is easy, reliable transmission gap adjusting mechanism of gantry numerical control cutting machine operates steadily thereby provide.
According to technological scheme provided by the invention, transmission gap adjusting mechanism of gantry numerical control cutting machine comprises by the first bolt and is connected to fixed base on frame, it is characterized in that: fixed base is rotationally connected the retarder pedestal by rotating shaft, fixing retarder on the retarder pedestal, on the output terminal of retarder, gear is installed, gear front end and tooth bar are connected with a joggle.Described retarder base via shaft is held the connection gear.Connect limiting bracket by the 3rd bolt on described fixed base, limiting bracket is provided with through hole, passes caging bolt in through hole.Be threaded retarder pedestal side of described caging bolt front end, caging bolt rear end connect packing ring, are provided with spring between packing ring and limiting bracket.
Further, be provided with copper sheathing between fixed base and rotating shaft.
Further, fixed base connects respectively two the first bolts up and down.
Further, be provided with spacer between bearing and retarder pedestal.
Further, caging bolt and retarder pedestal are by the nut check position.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is ingenious, and is easy to adjust, and assembly space is large; Reduced the processing request of frame; And reduced the phenomenon that expensive reduction gearbox output shaft ruptures, and reduce the maintenance rate that speed reducer is changed, thereby reduced manufacture cost, improved quality of product.

Embodiment
Following the present invention is further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 2, the present invention mainly comprises by the second bolt 15 and is connected to fixed base 2 on frame 1, and fixed base 2 is rotationally connected retarder pedestal 5 by rotating shaft 4.Fixing retarder 10 on described retarder pedestal 5 is installed gear 6 on the output terminal of retarder 10, gear 6 front ends and tooth bar 7 are connected with a joggle.
Described retarder pedestal 5 connects gear 6 by bearing 8, is provided with spacer 9 between bearing 8 and retarder pedestal 5.Described bearing 8 can play protection retarder output terminal and avoid stressed fracture.
Connect limiting bracket 16 by the 3rd bolt 17 on described frame 1, limiting bracket 16 is provided with through hole, passes caging bolt 11 in through hole.Be threaded retarder pedestal 5 sides of described caging bolt 11 front ends, caging bolt 11 rear ends connect packing rings 18, are provided with spring 12 between packing ring 18 and limiting bracket 16.Described caging bolt 11 and retarder pedestal 5 are by nut 13 locked positions.
Be provided with copper sheathing 3 between described fixed base 2 and rotating shaft 4, reduce friction by copper sheathing 3.
Described fixed base 2 connects respectively two the first bolts 14 up and down.
The present invention drives complete machine and vertically moves, and adopts the gear of retarder on output terminal to be meshed with tooth bar longitudinally, does vertically toward instead moving thereby drive complete machine.Be connected by rotating shaft 4 between retarder pedestal 5 and fixed base 2, can freely rotate in the several angle scope.Caging bolt 11 limits the position of retarder pedestal 5, makes gear 6 and tooth bar 7 mesh all the time.In the situation that engagement is bad, suitably unclamp the second bolt 15, each two bolts up and down of the first bolt 14 are headed on frame 1 to be screwed into and to twist and move back, being screwed into the direction of moving back will according to the direction of gear 6 inclinations, if gear 6 is oblique, will make top two bolts of the first bolt 14 be screwed into left, below two bolts twist and move back, make fixed base 2 drive adjustments that be tilted to the right of other links and gear 6, until till checking gear 6 and tooth bar 7 engagements well, then tighten the second bolt 15.
