Description

Electromagnetic vibrating machine for hand tools refers to hand tools designed for chasing in the manufacture of paintings on metal and jewelry.

Known electromagnetic vibrator [patent RU 2472276 C1, IPC Н02K 41/03, published 01/10/2013], comprising a housing on the inside of which are located bearings. Sensors are available to monitor the position of the moving part of the engine associated with the monitoring system. In the first embodiment, return springs are arranged coaxially with the levers. Hooks are located on the moving part. According to the second option, the control system is located in the housing, the levers and control systems are made on the moving part, and the hooks, respectively, on the housing. The levers are made with a retractable core. The difference between the third option and the second is that the levers have a hinge mechanism, are located inside the housing in one transverse plane and are made in the form of sectors. The movement of the moving part occurs on the rollers. The housing is movable, and the movable part is mounted on a fixed mechanism.

The disadvantage of the analogue is the design complexity and providing only one movement.

Known electromagnetic vibrator [patent RU 2130227 C1, IPC Н02K 33/00, Н02K 33/14, published May 10, 1999] containing an electromagnet and an armature made in the form of two identical movable working parts with a gap between them, each of which is a pair half rings of ferromagnetic material, fastened with washers of non-magnetic material. The movable working parts have an elastic connection with each other and are mounted with the possibility of rotation one relative to another. An electromagnet and an armature are mounted on an alternating current bus.

A disadvantage of the analogue is the inability to attach the tool.

A push-pull electromagnetic vibrator is known [patent SU 1762371 A1, IPC Н02K 33/14, published September 15, 1992], where the movable part is made in the form of a non-ferromagnetic rocker mounted on an elastic system with the possibility of rotational movement around a fixed central axis, on both sides of which two ferromagnetic anchors are fixed at opposite ends, and the corresponding electromagnets are mounted on a fixed base, and the windings of the opposite lying electromagnets are connected in parallel and After series-connected capacitors are connected to an AC voltage source.

The disadvantage of the analogue is the design complexity, low reliability and significant impact of vibration on the hands of the operator.

Closest to the proposed tool is a vibrator [patent SU 1405099 A1, IPC Н02K 33/14, published June 23, 1988] containing two electromagnets with two windings placed on opposite sides of a ferromagnetic armature mounted on a movable system, and two identical resonant circuits, formed by one of the windings of each electromagnet and a capacitor connected to it in parallel, the other winding of each electromagnet is connected to the AC network through a resonant capacitor connected in series to it ntura opposing electromagnet.

The disadvantage of the closest analogue is the design complexity and the lack of the ability to attach the tool.

The objective of the invention is to reduce the overall performance, simplify the design, expand the functional and technological capabilities due to the implementation of a ferromagnetic armature in the form of a disk with slots and a tool in the form of a rod with a clamping chuck for fastening the tool, expanding the scope for the jewelry industry by performing an electric drive in the form of electromagnets and ferromagnetic anchors.

EFFECT: increased accuracy of positioning of a hand tool.

The problem is solved and the technical result is achieved by the fact that in an electromagnetic machine of vibrational action for a hand tool containing a housing, two electromagnets with two windings, a ferromagnetic armature, according to the invention, the ferromagnetic armature is made disk, two electromagnets are placed on opposite sides of the ferromagnetic disc armature with radial slots mounted on the rod with the possibility of movement along the axis of the rod from the initial position in the middle part of the body up and down, while at the end A chuck chuck is attached to the rod with the ability to attach the tool, and magnets are installed in the middle part of the body with the possibility of returning the rod to its original position.

The invention is illustrated by drawings. In FIG. 1 shows a general view of an electromagnetic impact machine; FIG. 2 shows a top view in section.

An electromagnetic vibration machine for a hand tool contains (Fig. 1) a housing 1, a winding 2, a ferromagnetic disk armature 3 with radial slots, a rod 4, a chuck for holding the tool 5. Permanent magnets 6 and a damper 7 are located on the body 1. Permanent magnets 6 are made with radial slots for centering the ferromagnetic disk armature 3 (Fig. 2).

An electromagnetic vibration machine for a hand tool operates as follows. When voltage is applied to the winding 2 in the first half-cycle, the ferromagnetic disk armature 3 with radial slots moves in one direction, and in the second half-cycle, the ferromagnetic disk armature 3 with radial slots moves in the opposite direction. Thus, there is an oscillatory process of a ferromagnetic disk armature 3 with radial slots, the rod 4 and the clamping chuck connected to it for mounting the tool 5, this ensures the execution of the process. The alignment of the ferromagnetic disk armature 3 is provided by permanent magnets 6 located along its perimeter. The oscillation frequency of the instrument and magnetic forces are regulated from a controlled source of electrical energy. Damper 7 in FIG. 2 contributes to the protection of the human hand from the vibration of the instrument.

So, the claimed invention allows to reduce such indicators: as the mass and dimensions of the electromagnetic vibrating machine for a hand tool, to increase the accuracy of positioning the tool and expand its scope for the jewelry industry by performing an electric drive in the form of cylindrical electromagnets and cylindrical anchors and expand the functional and technological capabilities due to the implementation of a ferromagnetic anchor in the form of a disk with slots and a tool in the form of a rod with a chuck m for fastening tool.
