Description

Rail type guide mechanism of cutting machine

Technical Field

The invention relates to a cutting machine used in the light industry, in particular to a precise guide mechanism of a mechanical transmission or hydraulic transmission cutting machine.

Background

The cutting machine is a special device used in the light industry for blanking, punching, indentation and other processing processes of flexible materials, a machine type which is driven by machinery or hydraulic pressure is commonly used, power drives an upper template or a lower template of the cutting machine to move vertically upwards or downwards through the mechanical transmission or the hydraulic transmission, the processing of the materials is realized through a die arranged on the upper template or the lower template, the vertical up-and-down movement of the upper template or the lower template needs a guide mechanism to ensure the reliability and the precision of the operation, the guide mechanism of the cutting machine has a plane type and a four-column type, the plane type guide mechanism realizes the guide purpose by utilizing two planes arranged at the left side and the right side of the cutting machine, the plane type guide mechanism has simple structure and easy processing, but the guide precision is not high, and only can be applied to the machine type of the low-end cutting machine, the four-column type guide mechanism realizes the guide through circular guide columns and guide sleeves arranged at the four corners of, the guide precision is high, the application is wide, in the production practice of many years, some defects of the four-column type guide mechanism are gradually revealed, the development and application of the guide mechanism are influenced, firstly, the four-column type guide mechanism has higher requirements on processing, the performance of the same qualified part after being assembled has certain difference, an effective compensation mode is not available for eliminating the difference, secondly, the guide column or the guide sleeve can only be replaced after being worn, the requirements on the maintenance and the repair of equipment are higher, the defects of the four-column type guide mechanism do not have urgent solution requirements on the middle and low-end cutting machine type, but the problem which needs to be considered and solved for a high-speed high-precision high-end cutting machine is solved.

Disclosure of Invention

The invention aims to overcome the defects of the guide mechanism of the existing four-column type cutting machine and provide a track type guide mechanism which is high in precision, can be compensated and is easy to maintain.

The technical scheme of the invention is as follows: the rail type guiding mechanism of the cutting machine comprises a guide rail, a sliding block and a connecting block, the clamp plate, panel and coupling nut, two guide rails are a set of, two sets of symmetry vertical fixation are at the both ends of fuselage under the guillootine, there is a slider on every guide rail, slider and guide rail sliding fit, the slider can be on the guide rail vertical motion, there is the axle to stretch at both ends about the slider, the axle head that the axle stretched has the screw thread, the upper end axle of slider is stretched by coupling nut and the cope match-plate pattern of guillootine and is fixed, the lower extreme axle of slider is stretched by coupling nut and connecting block and is fixed, the cope match-plate pattern of guillootine, the frame construction of 4 slider and connecting block constitution motion on the guide rail, the rigidity of reinforcing mechanism and the synchronism of motion, the cooperation department of guide rail and slider has the panel, the clamp plate is fixed on the slider, there is the screw on the clamp plate, screw tip contact panel on the clamp.

The guide rail has rectangle, triangle-shaped or forked tail, and the same group of guide rail rectangle is paird with triangle-shaped and is constituteed or rectangle and forked tail are paird and are constituteed, has the constant head tank on the guide rail installation face at fuselage both ends under the guillootine, and the guide rail is fixed by the screw in the constant head tank, and the guide rail can be changed after damaging or wearing and tearing, convenient maintenance.

The invention has the beneficial effects that: the clearance between the guide rail and the sliding block of the rail type guide mechanism of the cutting machine can be adjusted, so that the machining or abrasion error can be compensated, the movement precision of the cutting machine is ensured, and meanwhile, the guide rail is convenient to disassemble and convenient to maintain.

The specific implementation mode is as follows:

the invention is further illustrated with reference to the following figures and examples.

FIG. 1 is a front view of a rail type guide mechanism of a cutting machine, FIG. 2 is a partial sectional view of the same set of rails on one side, a dovetail guide rail 4 and a rectangular guide rail 10 are fixed on a lower machine body 9 of the cutting machine, a dovetail slider 3 and the dovetail guide rail 4 are in sliding fit, a rectangular slider 14 and the rectangular guide rail 10 are in sliding fit, upper end shafts of the dovetail slider 3 and the rectangular slider 14 are fixed by an upper connecting nut 2 and an upper cutting machine template 1, lower end shafts of the dovetail slider 3 and the rectangular slider 14 are fixed by a lower connecting nut 8 and a connecting block 7, a pressing plate 5 is fixed on the rectangular slider 14 by a pressing plate fixing screw 11, a pressing plate fastening screw 12 and a pressing plate 5 are in threaded connection, the top end of the pressing plate fastening screw 12 is abutted against a rectangular gib 13, a gap between the rectangular guide rail 10 and the rectangular slider 14 can be adjusted by changing the thickness of the rectangular gib 13, actual contact surfaces, be provided with forked tail panel 15 on one side,

slider holding screw

6 and 3 threaded connection of forked tail slider, the top of slider holding screw 6 is supported on forked tail panel 15, changes the thickness of forked tail panel 15 and just can adjust the clearance between forked tail guide rail 4 and the forked tail slider 3.

The cutting machine adopting the rail type guide mechanism can eliminate the influence of machining errors and abrasion on the matching precision, ensure that the relative motion between the upper template 1 of the cutting machine and the lower machine body 9 of the cutting machine is accurate and reliable, meet the cutting requirement of high speed and high precision at present, and has the advantages of simple structure, mature machining process and convenient installation and maintenance.
