Description
Technical field
The invention belongs to leather cutting equipment, especially a kind of leather cutting head.
Background technology
The Chinese leather industry has contained main body industries such as process hides, shoemaking, fur clothing, leather goods, fur and goods thereof, and the leather usage quantity is huge.At present, leatherware processing enterprise carries out leather cutting by the auxiliary mode of artificial or a small amount of mechanical means, this primary cutting mode, and the leather utilization ratio is low, labor strength is big, and cost is higher.Along with reducing gradually and the continuous rising of labor cost of skilled worker, a kind of high speed of needs, leather cutting equipment efficiently.
The main difficult point and the key point of this equipment are the designs of leather cutting head.This cutting head becomes at a high speed cutting movement up and down to high speed rotary motion by electric motor driving.Because during high-speed cutting, acceleration can produce sudden change, mechanism's vibrations noise is bigger, has influenced cutting accuracy.So require under certain cutting accuracy and fair speed, guarantee that machine vibration is less.During at present domestic electronic leather cutting head work, exist the machine vibration noise serious, the low deficiency that waits of cutting accuracy difference and cutting efficiency.
Summary of the invention
For the vibrations noise that overcomes existing electronic leather cutting head is serious, cutting accuracy difference and the low deficiency of cutting efficiency, the invention provides a kind of electric vertical leather tailoring and cutting head little, that cutting speed in feet per minute is fast, cutting accuracy is high that shakes.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of electric vertical leather tailoring and cutting head, comprise pedestal and motor, described motor is arranged in vertical direction, described motor is connected with transmission shaft by shaft coupling, conical gear is installed in the lower end of described transmission shaft, described conical gear and the subumbrella toothing of going up, one side of described conical gear down is connected with an end of the excentric shaft of arranging in horizontal direction, described excentric shaft is sleeved on the pedestal rotationally, the described opposite side of conical gear down is connected with tunnel shaft, the medullary ray of described tunnel shaft is positioned on the different straight lines with the medullary ray of described excentric shaft, one end of described tunnel shaft is connected with the upper end of expansion link by hinges, the middle part of described expansion link can slide up and down to be sleeved in the fixed jacket, and the blade in order to the cutting cladding is installed in the lower end of described expansion link.
As preferred a kind of scheme: described hinges comprises additional bearing, described additional bearing is installed in an end of tunnel shaft, flat disk and following flat disk are installed in the upper end of described expansion link, and described additional bearing is installed on described going up between flat disk and the following flat disk.This scheme have take up room little, the advantage of compact construction.
Or: described hinges comprises connecting rod, and an end of described connecting rod and described tunnel shaft is hinged, and the upper end of the described connecting rod the other end and described expansion link is hinged.
Technical conceive of the present invention is: when the drive-motor that is in vertical direction begins to rotate, power is imported from vertical direction, fitting by a pair of conical gear is used, change the power transmission direction, become horizontal transmission, under horizontal transmission,, change high-speed cutting campaign up and down into, finish the function of cladding cutting by offset cam mechanism.
Beneficial effect of the present invention mainly shows: compact construction, and transmission of power is steady, and the vibrations noise is little, cutting accuracy height, fireballing a kind of electric vertical leather tailoring and cutting head.
Description of drawings
Fig. 1 is the structural representation of electric vertical leather tailoring and cutting head.
Fig. 2 is the STRUCTURE DECOMPOSITION figure of electric vertical leather tailoring and cutting head.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
See figures.1.and.2, a kind of electric vertical leather tailoring and cutting head, comprise pedestal and motor 1, described motor 1 is arranged in vertical direction, described motor 1 is connected with transmission shaft by shaft coupling 8, conical gear 11 is installed in the lower end of described transmission shaft, described conical gear 11 and the subumbrella toothing of going up, one side of described conical gear down is connected with an end of the excentric shaft of arranging in horizontal direction 5, described excentric shaft 5 is sleeved on the pedestal rotationally, the described opposite side of conical gear down is connected with tunnel shaft, the medullary ray of described tunnel shaft is positioned on the different straight lines with the medullary ray of described excentric shaft 5, one end of described tunnel shaft is connected by the upper end of hinges with expansion link 13, and the middle part of described expansion link 13 can slide up and down to be sleeved in the fixed jacket 19, and the blade 17 in order to the cutting cladding is installed in the lower end of described expansion link 13.
Described hinges comprises additional bearing 6, and described additional bearing 6 is installed in an end of described tunnel shaft, and flat disk and following flat disk are installed in the upper end of described expansion link 13, and described additional bearing 6 is installed on described going up between flat disk and the following flat disk.This scheme have take up room little, the advantage of compact construction.
Or: described hinges comprises a bar, and an end of described connecting rod and described tunnel shaft is hinged, and the upper end of the described connecting rod the other end and described expansion link is hinged.This programme has adopted classical toggle to realize, comparatively speaking, it is bigger to take up room.
Described shaft coupling 8 is positioned at coupling sleeve 7, and described transmission shaft is installed in two right bearings 9, and right bearing 9 is installed on the right bearing overcoat 10; Described upward conical gear 11, following conical gear all are positioned at and connect this seat 12, and the upper end of described additional bearing 6 and described expansion link 13 all is positioned at and connects this seat 12; Described excentric shaft 5 is installed in the left bearing 3, and described left bearing 3 is installed in the left bearing overcoat 4, and described bearing outside 4 is fixedlyed connected with left side step cover 2; Described this seat of connection 12 is fixedlyed connected with lower cover 14, described telescopic shaft 13 is sleeved in two lower bearings 15, be provided with bearing spacer 16 between described two lower bearings 15, described fixed jacket 19 is installed in cutter head and fixes in this seat 20, described guiding overcoat 21 is positioned at cutter head to be fixed outside this seat 20, blade permanent seat 18 is installed in the lower end of described expansion link, and blade 17 is installed on the blade retainer 18.
The working process of present embodiment is: when needs cutting cladding, the motor 1 that is installed in vertical direction begins to rotate, driving upward by shaft coupling 8, conical gear 11 vertical direction rotatablely move, again by last conical gear 11 be installed in subumbrella gear meshing on the excentric shaft of horizontal direction, and drive the rotation of excentric shaft 5 and following conical gear.Because the medullary ray of the medullary ray of the outrigger shaft of an end of the excentric shaft 5 close flank of tooth and the other end axle of excentric shaft is not on same straight line, and excentric shaft is equipped with additional bearing 6 near the outrigger shaft of an end of the flank of tooth, so described additional bearing 6 and excentric shaft have been formed an offset cam mechanism.Offset cam mechanism by excentric shaft 5 and additional bearing 6 formations, thereby the rotation of the rotating band moving cam (being auxiliary bearing 6) by excentric shaft 5, promote an end and have two disks and the other end telescopic shaft 13 that a blade 17 is installed that is fixed and do cutting movement up and down reciprocatingly, finish the function of cutting cladding.
