Abstract
A lower cutter installing structure of a front fly sewing machine comprises an installing plate. The lower cutter installing structure is characterized in that a driving motor is fixedly installed on one side of the installing plate; the output shaft of the driving motor extends to the other side of the installing plate after running through a shaft hole of the installing plate; the other side, which extends out of the other side of the shaft hole, of the driving motor is connected with a cylinder through a cam mechanism; an output shaft of the cylinder is provided with a connecting support plate; a bearing pack is fixed to the installing plate; bearing pack guide shafts pass through via holes of the connecting support plate and can move to and fro vertically under the driving of the connecting support plate; and the ends, which extend out of the via holes of the connecting support plate, of the bearing pack guide shafts are provided with lower cutters. The lower cutter installing structure of the front fly sewing machine is characterized in that the driving mechanism and the lower cutters are separated and the driving mechanism is fixedly installed, so that the driving mechanism is prevented from moving when the lower cutters move downward for cutting, the stability of the whole mechanism is improved, the number of the driving motors is reduced and the production cost is saved.
Description
Technical field
The utility model belongs to textile clothing mechanical field, specifically just relates to a kind ofly for making the button stay sewing machines of left front on clothes, especially relates to button stay sewing machines lower cutter mounting structure.
Background technology
Apparel industry is a very traditional industry, the mankind have the history of making clothes for thousands of years, it is that apparel industry has been shone vitality that modern socialization is produced, each parts of clothes all start to carry out large-scale mechanical automation production, for example on clothes, process a left front, generally there are two kinds of methods, the first is used common flat seam machine sewn by hand, another kind is to use crosspointer button stay sewing machines automatic sewing, while using common flat seam machine sewn by hand, on cloth, make several sutures now, then taking off cloth cuts apart with a knife or scissors the part between suture with scissors or blade again, during manual suture, be difficult to control sutural length, linearity and gradient, and hand cutting easily cuts up cloth cutting, technology controlling and process quality is unstable, while using crosspointer left front automatic sewing, usually the two eedle rear sides at crosspointer button stay sewing machines are provided with cutter assembly, and for cutting otch between suture, existing cutter driving motor and lower cutter are installed together, motor drives lower cutter motion under cylinder drives, this lower cutter mounting structure is because driving mechanism and cutting knife are installed together, lower cutter motion, and driving mechanism is also in motion, cause stability inadequate, machine easily occurs and interfere fault, complex structure, is unfavorable for installing.
Utility model content
The purpose of this utility model is that lower cutter Component driver mechanism and the cutting knife for existing button stay sewing machines is installed together, and the technological deficiency that cutting knife stability is not strong, provides a kind of button stay sewing machines lower cutter mounting structure, strengthens the stability of cutting knife work.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of button stay sewing machines lower cutter mounting structure, it comprises installing plate, it is characterized in that: drive motors is installed on installing plate one side, the output shaft of drive motors reaches installing plate opposite side through the axis hole of installing plate, drive motors stretches out on the opposite side of axis hole and is connected with cylinder by cam mechanism, the output shaft of cylinder is provided with connection gripper shoe, bearing group is fixed on installing plate, bearing group leading axle passes the via hole that connects gripper shoe, bearing group leading axle can move back and forth up and down under connection gripper shoe drives, bearing group leading axle passes the one end that connects gripper shoe via hole lower cutter is housed.
The output shaft of described cylinder is installed with connection gripper shoe, and drive motors can drive the cylinder band gripper shoe that is dynamically connected to move up and down by cam mechanism.
Described bearing group comprises 4 linear bearings, and symmetry is positioned at cylinder both sides respectively, and cutting knife installing plate is equipped with in the leading axle lower end of bearing group lower end, and cutting knife installing plate lower surface is equipped with lower cutter.
Described drive motors is servomotor.
Beneficial effect
The button stay sewing machines lower cutter mounting structure that the utility model provides, driving mechanism and lower cutter are separated, driving mechanism fixed installation, while having avoided lower cutter to cut off motion downwards, driving mechanism moves together, increase the stability of whole mechanism, reduced the quantity of drive motors, saved production cost.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in accompanying drawing 1～5, a kind of button stay sewing machines lower cutter mounting structure, it comprises installing plate 1, it is characterized in that: drive motors 2 is installed on installing plate 1 one sides, the output shaft of drive motors 2 reaches installing plate 1 opposite side through the axis hole 101 of installing plate 1, drive motors 2 stretches out on the opposite side of axis hole and is connected with cylinder 3 by cam mechanism 201, the output shaft of cylinder 3 is provided with and connects gripper shoe 4, bearing group 5 is fixed on installing plate 1, bearing group 5 leading axles 501 pass the via hole that connects gripper shoe 4, bearing group 5 leading axles can move back and forth up and down under connection gripper shoe 4 drives, bearing group 5 leading axles pass the one end that connects gripper shoe 4 via holes lower cutter 6 are housed.
The output shaft of described cylinder 3 is installed with and connects gripper shoe 4, and drive motors 2 can drive cylinder 3 to be with the gripper shoe 4 that is dynamically connected to move up and down by cam mechanism 201.
Described bearing group 5 comprises 4 linear bearings, and symmetry is positioned at cylinder 3 both sides respectively, and cutting knife installing plate 7 is equipped with in leading axle 501 lower ends of bearing group 5 lower ends, and cutting knife installing plate 7 lower surfaces are equipped with lower cutter 6.
Described drive motors 2 is servomotor.
The utility model in the course of the work, first cylinder 3 actions, cylinder output shaft stretches out, and by schematic structure, drives lower cutter 6 cutting knifes to be moved down into operating position, and then drive motors 2 work, by cam structure 201, connect lower cutter 6 and drive lower cutter 6 to start working; Complete when work, lower cutter 6 stops action, and cylinder output shaft is regained, and lower cutter 6 resets)
The utility model separates driving mechanism and lower cutter, driving mechanism fixed installation, and while having avoided lower cutter to cut off motion downwards, driving mechanism moves together, has increased the stability of whole mechanism, has reduced the quantity of drive motors, has saved production cost.
