Description

The invention relates to the organization of a jeweler's workplace, namely, to secure fixtures and parts when performing precision metalwork, mechanical and jewelry work.

One of the most important conditions for quality work in work and training, to reduce the loss of precious metals (gold, silver) and reduce fatigue, is the master's workplace. Jewelry workbenches come in different designs, but in any case there are mandatory requirements for each jewelry place. The workbench itself should occupy a stable position, the worktop of the workbench (top plate) should be massive and have a segment cut (working cell) with a mounting place for various devices, for example a finel. The finagel can be fixed by tight fitting the shank into the hole in the end face of the center of the working cell or have a screw fastener that allows it to be held without play. Finagel is made of hard wood and serves as an emphasis during the work of the jeweler at the workbench. For the collection of waste during the processing of products, a sliding metal box under the working cell of the workbench is used.

Various designs are known for supporting products during repair using articulated bushings that allow the product to be rotated 360 ° in a horizontal plane.

For example, a support device for repairing products is known, comprising a base, a telescopic socket for a ball with a U-shaped channel in the wall, a ball, a side stopper of the ball, a product supporting element and a rod for connecting the ball to the element (US Pat. No. 4,787,613). The known device allows you to install the product at different heights, rotate in a horizontal plane 360 °, and also change its position from horizontal to vertical and vice versa, however, it is ineffective in processing small-sized products.

A well-known universal holder containing a base, a nest for the ball, with the possibility of vertical movement, the ball, the lower stopper of the ball, a glass, the wall of which covers the lower part of the upper hemisphere, the casing and the rod connecting the ball and the casing (German application laid out No. 102005001348). With this holder, you can rotate the product around vertical, set it obliquely, change its position from vertical to horizontal and vice versa, but it is impossible to move the product in a plane perpendicular to the axis of the inclined rod, which limits its operational capabilities.

A well-known working tool (US Pat. RF PM 93727), containing a base, a ball nest placed on it, a ball located between the nest and the cap covering the lower part of the upper hemisphere, the housing, the jaws mounted on the housing, the power drive of the jaws and the rod for connection ball with the body. A vertical axial hole is selected in the ball, and the end of the rod is mounted in the hole with the possibility of rotation around the axis, while a horizontal blind hole is provided in the housing, and coaxial holes are made in the rod and the body, forming a channel communicated with the blind hole, the screw being placed in blind hole, kinematically connected with a pin located in the channel, spring-loaded towards the blind hole and having the ability to interact with the side surface of the hole in the ball. This device, although devoid of the disadvantages of previous designs, also has disadvantages - low operational characteristics, namely narrow specialization, insufficient versatility compared to the claimed device, in particular, the change of tool is inconvenient.

A device for carrying out jewelry work is known, comprising a base with a handle, a clamp pivotally mounted on one of the sides of the base, and a guide rod rigidly fixed on the end of the base, on which a stop with a clamping screw is mounted with the possibility of movement and fixation (RF patent on PM 3708) . The clamp is removable with the possibility of installation on the opposite side of the base.

Another analog of this type of technical solutions is a device including a base, a ball socket, a ball, a ball stopper - a shaft with an eccentricity, a glass whose wall covers the lower part of the upper hemisphere, a body and a rod connecting the ball and the body (application EP No. 0201817). However, it is also inefficient in the processing of small-sized products.

Known positioning device for the production and repair of jewelry (EP No. 0335126), which allows you to work in numerous positions. The main disadvantage of the device is its complexity and cumbersomeness, as well as the unsuitability in production and high cost, because it includes all the devices at the same time and there is no way to use one tool fully so that it does not interfere with another. It turns out that this device needs a separate table and at the same time it is inconvenient to use it on a jewelry workbench, because it is almost a mini workbench itself, but without a metal collection tray and hand rests.

The closest technical solution is a combined clamping device (US Pat. No. 2026776) containing a c-shaped clamp, a screw with a clamping base installed in the lower part of the clamp, a working surface with a fixed clamp, combinatorial nozzles. In the mounting plate with technological holes, grooves are made in the form of a trapezoid, corresponding to the bevels of the second shelf of the clamp. Combinatorial nozzles (anvil, cone nozzle for more accurate correct work, rolling of thin products and wire) are designed for installation on a mounting plate. The half-clamp can turn around its axis-screw 180 °; The principle of attaching nozzles to an oval plate using fixing screws. The disadvantage of the prototype is low efficiency and lack of convenience compared to high-grade tools.

Common disadvantages of the known technical solutions are cumbersome, low efficiency, a narrow range of tasks, is not suitable for industrial needs (and also are not a universal kit for the work of a domestic craftsman).

The problem to which the claimed combined clamping device is aimed is to improve the operational characteristics of combinatorial nozzles by ensuring their accurate spatial orientation. Another type of technical result, the preparation of which this invention can provide in comparison with the closest analogue, lies in the convenience of the jeweler, especially using a different set of nozzles and removable devices with their possible orientation in space.

The device can be used not only by jewelers, watchmakers, but also by various kinds of fashion designers, modelers, sculptures, artists working with small plastics, ceramics, etc., as well as various kinds of home craftsmen and craftsmen. To do this, the device is divided into classes: professional and amateur.

The objective of the invention is to increase productivity and expand the technological capabilities of the combined clamping device.

The task is achieved through the use of a combined clamping device containing a C-shaped clamp with a hole in the upper part for fixing the mounting module, and a screw with a fifth mounted in the lower part of the clamp for mounting on the table. In this case, the device is equipped with a removable device for mounting combinatorial nozzles installed in the mounting module, including a cylindrical part, at one end of which a clamp is made, while holes are made on the lateral surface of the clamp for additional installation of the mounting module using a rotation mechanism containing a threaded nozzle with a clamp, installed in the hole made in the clamp.

In addition, it is recommended to use the following clips:

- the clamp of the removable fixture is made in the form of a circle (9) with a hole in the center for installation as a combinatorial nozzle of the finel (see Fig. 3a);

- the clamp of the removable device is made in the form of a clamp (10) with holes for rigid installation as a combinatorial nozzle of the final gel (see Fig. 3b);

- the clamp of the removable device is made in the form of an adapter (17) with an opening for installing a single-joint sleeve with an installation base (18) and a clamping screw (24) for installing a universal working surface (25) (see Fig. 4b).

In addition, the following combinatorial nozzles are recommended:

- an engraver in the form of a L-shaped cylindrical rod (27) with the possibility of fixing one of its ends in the mounting hole of the mounting module and the working surface of the engraver (29) with a control slider (28) on the other end of the rod with the possibility of installation at different heights (see Fig. . 5 B).

Preparation of the combined clamping device for operation is as follows.

The clamp (1) of the combined clamping device is fastened to the bench table using the fifth screw (6). Depending on the work being performed, the mounting module (2) is installed on the clamp either on the upper surface or on the side surface of the clamp, or both modules simultaneously (see Fig. 1) using the rotation mechanism (5), which is a threaded nozzle with a clamp installed in holes (30). For convenience in operation, two additional holes (30) are made on the lateral surface of the clamp. Then, the cylindrical part of the selected removable device for a certain type of work, for example with combinatorial nozzles - a universal working plane, or finel, or engraver, is inserted into the mounting hole of the mounting module (3) due to the slot (26) and the loosened tightening screw (4). After its installation, the tightening screw (4) compresses the slot (26), fix the fastening module (2) firmly in the desired horizontal or vertical direction.

The combined clamping device is ready to work, complete tasks and is in a static state.

The use of a removable fixture with a latch in the form of a circle (9) for attaching the finel is necessary to perform work requiring constant rotation of the finel relative to the horizontal plane.

When using a clamp in the form of a clamp (10) for rigid fastening of the finel, work is performed that requires rigid fixation of the part at a certain angle and the desired position.

When using the clamp of a removable fixture made in the form of an adapter with a hole (17) and a clamping screw (4) for installing a single-joint sleeve (23), a universal working surface (25) for a vice (19) is attached to the mounting base (18). This design of the lock allows you to set a different position for combinatorial nozzles: 360 ° rotation around the axis due to the single-hinged sleeve (23), to change the position relative to the horizontal plane due to the orientation of the mounting module (2). You can change the position of, for example, the engraver relative to the vertical plane by using the L-shaped cylindrical rod of the engraver (27), on which the working surface of the engraver (29) of the claimed design is installed due to the slider (28) (see Fig. 5b). In addition, it is possible to change the angle of inclination of the final gel using the claimed design of the removable surface of the final gel (14) (see Fig. 3c).

To install the vise (19) on the universal working surface (25) in the desired position, loosen the ball tightening (20) with the locking screw (24), while it becomes possible to tilt the vise or surface (25) from the vertical axis by an angle of up to 30 °. In addition, when loosening the screw (24), the mounting base (18) is able to rotate in a plane perpendicular to the axis of the single-joint sleeve (23). After installing the universal working surface (25) in a position convenient for processing the product, by turning the knob of the locking screw (24), the ball (20) is secured in the socket (21).

The expansion of operational capabilities is achieved by quickly reinstalling the removable device with various nozzles, which can be oriented on 3 planes.

Thus, the proposed combined clamping device, which allows you to work with the installed product in any position, has successfully passed tests in jewelry workshops.

Suggested combinatorial nozzles: jewelry vice, wooden finel with metal fastening, wooden finel, made of oak and has the ability to replace the wooden part as it wears out; engraver and universal work surface for work with small plastics, for soldering, modeling and sawing. All nozzles have the ability to install in horizontal and vertical surfaces, rotation around the axis. The possibility of changing the wooden surface of the final gel is provided.
