Description

Circle cutting device

Technical Field

The utility model belongs to the technical field of cutting tools, and relates to a circle cutting device.

Background

A circle cutter, also called a circular quantitative sampler, is mainly used for cutting various small batches of circles of paper, cotton, chemical fiber, knitting and the like. For example, the Chinese patent document discloses a multifunctional modular circle cutter (No. CN 210256445U), which comprises an outer circle, a turntable, an inner circle cutting mounting plate, an extension arm, a tool bit clamp and a cutter, wherein the outer circle is in a circular ring shape; the turntable can be rotatably sleeved in the inner circle of the excircle and is suspended, and a strip-shaped groove which is through up and down is arranged on the turntable along the radial direction; the two inner circle cutting mounting plates are both positioned below the turntable and are respectively positioned on two sides of the strip-shaped groove, the other end of each inner circle cutting mounting plate is provided with a cutter mounting hole, and the cutter mounting holes are aligned with the strip-shaped grooves; the extension arm is a strip-shaped plate, one end of the extension arm is arranged on the turntable, a tool bit clamp is arranged in a tool mounting hole of the inner circle cutting mounting plate, and the other end of the extension arm is provided with the tool bit clamp; the cutter is arranged at the end part of the cutter head clamp, and the cutter point faces downwards. Although the multifunctional modularized circle cutter can realize circle cutting or circular ring cutting, the multifunctional modularized circle cutter has the following defects: cylindrical magnet and first elastic component have between the cutter that this multi-functional modularization circle cutting ware tool bit anchor clamps were fixed and adjusting nut, because first elastic component has scalability, so in-process at the cutter cutting because there may exist reciprocating of cutter position of atress difference, lead to the reliability that the cutter circle was cut not high.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides a circle cutting device. The utility model solves the technical problem of how to improve the reliability of the circle cutting of the cutter of the circle cutter.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides a circle cutting device, including the positioning seat, it is provided with the swivel becket to rotate on the positioning seat, be provided with the tool bit anchor clamps on the swivel becket, a serial communication port, the tool bit anchor clamps are including fixed cover, the top threaded connection of fixed cover has the capping, be equipped with the cutter in the fixed cover and can drive the push rod that the cutter reciprocated, the push rod is worn to establish the capping and rather than threaded connection, the upper portion cover of cutter is equipped with pressure regulating spring, the lower part cover of cutter is equipped with supporting spring, pressure regulating spring supports and establishes between capping and cutter, supporting spring supports and establishes between the bottom of cutter and fixed cover.

When the cutting tool needs to be adjusted to move downwards, the push rod only needs to be rotated downwards, the push rod moves downwards along the fixed sleeve, the push rod pushes the cutting tool to move downwards, the cutting tool moves downwards after compressing the supporting spring, and the cutting tool is abutted against the push rod under the action of the supporting spring; when cutter rebound needs to be adjusted, only the push rod needs to be rotated upwards, the push rod moves upwards along the fixed sleeve, the cutter moves upwards under the action of the supporting spring until the cutter abuts against the push rod, the push rod and the cutter of the structure are in direct contact, the push rod is in threaded connection with the sleeve cover, the sleeve cover is in threaded connection with the fixed sleeve, and therefore after the push rod drives the cutter to move up and down to adjust the position of the cutter, the cutter cannot shift in the axial direction due to stress, and therefore the reliability of circle cutting of the cutter of the circle cutter is improved.

The positioning rod used for limiting the rotation of the cutter is inserted between the first positioning groove of the fixing sleeve and the second positioning groove of the cutter, so that the cutter cannot shift in the circumferential direction due to stress, and the reliability of circle cutting of the cutter of the circle cutter is improved.

In the circle cutting device, a sliding groove is formed in the rotating ring, and a sliding block movably arranged in the sliding groove is arranged on the fixing sleeve.

During cutting, the position of the cutter in the rotating ring can be adjusted through the movement of the sliding block in the sliding groove, and circles with different diameters can be cut.

In foretell circle cutting device, be provided with the hole of wearing to establish that can supply fixed cover to wear to establish on the slider and be provided with the stop part in the bottom of wearing to establish the hole, fixed sheathe in and be provided with can form spacing complex bellying with the stop part, the inner wall of wearing to establish the hole evenly is provided with four stoppers along circumference, be provided with respectively on the bellying and form four spacing grooves of spacing complex with four stoppers, the top threaded connection who wears to establish the hole has the sliding closure cover, supports between the top of sliding closure cover and bellying and is equipped with fastening spring.

Above-mentioned structure makes fixed cover can set up on the slider firmly, and fix a position the angle of knife tip through the inside structure of fixed cover, avoid influencing the tangent circle of cutter because rocking of fixed cover, simultaneously, upwards stimulate fixed cover and make after the spacing groove breaks away from the stopper rotate 90 or 180 or 270 after fix again in the wearing hole (form spacing cooperation with four spacing blocks through four spacing grooves), and simultaneously, fastening spring can provide the holding down force under the effect of sliding cover, make fixed cover can set up on the slider more firmly, the cutter has also rotated 90 or 180 or 270 along with the rotation of fixed cover in step, at this moment, can cut the straight line through the removal cutter of slider along the spout, thereby make this cyclotomy ware can cut fan-shapedly.

In the above circular cutting machine, the rotating ring is provided with a hand rotating part for conveniently rotating the rotating ring.

In the circle cutting device, the rotating ring is provided with a first scale mark, and the first scale mark is positioned above the sliding groove.

In the circle cutting device, a second scale mark is arranged on the positioning seat along the circumferential direction and is located beside the rotating ring.

In the above circular cutting machine, the positioning seat is annular, a bearing is arranged in the positioning seat, and the rotating ring is arranged on the bearing.

Compared with the prior art, the circle cutting device has the advantages that: this circle ware cutting is fixed to be equipped with the cutter in the cover and can drive the push rod that the cutter reciprocated, push rod and cutter direct contact, and push rod threaded connection covers, cover lid threaded connection is sheathe in fixed, so after the push rod drives the cutter and reciprocates the position of adjusting the cutter, the cutter can not shift phenomenon because of the atress appear in the axial, furtherly, it is equipped with and is used for restricting cutter pivoted locating lever to insert between the constant head tank of fixed cover one and the constant head tank two of cutter, make the cutter can not shift phenomenon because of the atress appear in circumference, thereby improve the reliability of circle ware cutter circle of cutting.
