Background
In industrial production, it is common demand to cut processing to the material, and the cutter of high frequency cutting equipment on the existing market adopts the pneumatic drive mode, but this type of pneumatic cutting equipment can influence the frequency and the degree of depth of vibration at every turn all be different because of atmospheric pressure is unstable and flow is unstable, and atmospheric pressure is less, and the frequency is lower, and the translation rate just will reduce, and the cut-parts effect that otherwise cut out is just poor, and cutting strength is not enough moreover, produces the incomplete penetration or has the burr phenomenon easily when cutting multilayer material.
Disclosure of Invention
The invention aims to provide a high-frequency large-stroke electric vibration cutter, which drives a reciprocating sleeve head to move up and down at high frequency by the walking of steel balls on an inclined slide rail, so that the stroke distance of the cutter is fixed, and the cutter rotates mechanically and physically, so that the cutting force is strong enough, and the cutter is suitable for multi-layer cutting.
The technical scheme includes that the reciprocating cutter is characterized in that a shell, a shaft cover, a spring, a cutter cover, a motor, a coupler, a reciprocating shaft, a reciprocating sleeve head, a graphite copper sleeve, a positioning block, a cutter holder, a cutter, a steel ball and a bearing are sequentially connected and installed from top to bottom, the spring is sleeved on the shaft cover to enable the cutter cover to stretch and reset, the motor is installed in the shell, the reciprocating shaft is installed in the shaft cover through the bearing, one end of the reciprocating shaft is connected with a rotating shaft of the motor through the coupler, the other end of the reciprocating shaft is provided with the reciprocating sleeve head, the front end of the reciprocating shaft is inserted into a cavity of the reciprocating sleeve head, a sliding groove is formed in a shaft body at the front end of the reciprocating shaft in an inclined mode and annularly arranged on the shaft body, a hole is formed in the inner wall of the reciprocating sleeve head and is opposite to the sliding groove of the reciprocating shaft, and the steel ball is installed in the.
A cylindrical semi-closed cavity with an opening at the top is arranged in the reciprocating sleeve head, the front end of the reciprocating shaft is inserted into the cavity, and the steel balls can slide along the sliding grooves when the reciprocating shaft rotates and force the reciprocating sleeve head to reciprocate up and down in the shaft cover; the locating piece is installed on the cutter arbor of reciprocal pullover front end through the graphite copper sheathing, and the cutter inserts in the locating piece and installs on the cutter arbor of reciprocal pullover through the cutter holder, and the front end of locating piece is provided with the bayonet socket, and the restriction is reciprocal pullover to follow the reciprocating shaft rotation in the bayonet socket is inserted to the both ends of cutter holder.
The distance between the highest point and the lowest point of the chute on the circulating reciprocating shaft is less than the depth of a cavity of the reciprocating sleeve head, and the length of the transverse chute section between the highest point and the lowest point of the chute is less than the diameter of a steel ball; the hole on the inner wall of the reciprocating sleeve head is opposite to the middle section of the sliding groove of the reciprocating shaft.
The working principle of the invention is that the rotating speed of a high-frequency motor is 3000 r/min, the frequency of the electric vibrating cutter is 3000 r/min, an inclined surrounding chute is arranged on a reciprocating shaft, the highest point and the lowest point of the chute determine the size of the up-and-down moving stroke of the reciprocating sleeve head, when the reciprocating shaft rotates, a steel ball slides along the chute, and forces the reciprocating sleeve head to move up and down in a shaft cover in a reciprocating manner to drive a cutter to cut, the frequency of the cutter changes along with the change of the rotating speed of the motor, the cutting frequency can be controlled by controlling the rotating speed of the motor through a circuit according to production requirements, and the frequency can not influence the stroke and cutting strength of the cutter.
The invention has the advantages of reasonable structure, stable and safe operation, can flexibly adjust the cutting frequency according to the characteristics of various cut materials, and simultaneously can not influence the stroke and the cutting strength of the cutter.
