Description

Technical Field

[0001] The utility model mainly relates to a bracket structure for a wire drawing fixture.

Background Art

[0002] The metal wire drawing process usually involves using abrasive tools to form specific textures on the surface of workpieces, and these textures can be straight lines, random lines, corrugations or spiral lines, etc. In the production of hardware parts, wire drawing treatment not only provides an aesthetic appearance but also increases the abrasion resistance and corrosion resistance of the handles.

[0003] When polishing, grinding and wire drawing hardware parts, fixtures are used to position the hardware fittings, and then a series of operations such as grinding and polishing are carried out. The existing fixtures for the production of hardware fittings are only for fixing hardware and polishing, grinding and wire drawing products with small elasticity, and cannot polish, grind and wire draw the 3D free surface of complex curved elastic hardware products. In view of this, we provide a structural solution for the curved surface support of a wire drawing fixture for hardware parts.

[0018] The embodiments of the present invention are described in detail below. The embodiments are shown in the accompanying drawings, wherein the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions.

[0019] In the present invention, unless otherwise specified and limited, the terms "assembly", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, but cannot be understood as limiting the utility model.

[0021] The preferred embodiment provided by the utility model is as follows: Figures 1 to 4 As shown, a bracket structure for a wire drawing fixture includes a base 1 and a curved surface support assembly 2. The base 1 is provided with an embedding position 11, and a plurality of locking holes 12 are arranged along the base 1. The curved surface support assembly 2 and the base 1 are a split assembly structure. The curved surface support assembly 2 can be adjusted to be installed in the base 1 according to the part of the workpiece that needs to be processed;

[0022] The curved surface support assembly 2 includes a support bowl 3, a ball head 4, a screw 5, a locking piece 6, a telescopic support rod 7 and a top connection piece 8; the support bowl 3 includes a bowl portion 31 and a locking rod 32, and the locking rod 32 is connected to the locking hole 12 to fix the curved surface support assembly 2 to the base 1; the locking rod 32 and the locking hole 12 are threadedly connected; the ball head 4 and the locking piece 6 are installed on the support bowl 3, and the ball head 4 can move on the support bowl 3, and the screw 5 passes through the support bowl 3 and is connected to the locking piece 6, so that the locking piece 6 is pushed by the screw 5 to press the locking piece 6 to limit the movement of the ball head 4 in the support bowl 3;

[0023] The telescopic support rod 7 is connected to the ball head 4, and the telescopic support rod 7 changes its angle along with the movement of the ball head 4. The top connecting member 8 is connected to the end of the telescopic support rod 7. The telescopic support rod 7 includes a first support rod 71 and a second support rod 72 which are connected to each other. The first support rod 71 is provided with a connecting hole 73, and the second support rod 72 is provided with an elastic protrusion 74. The elastic protrusion 74 is connected with the connecting hole 73 to limit the relative telescopic length of the first support rod 71 and the second support rod 72.

[0024] The bowl 31 is provided with a screw hole, and the screw 5 is screwed into the screw hole to adjust the extension of the screw 5. The greater the extension of the screw 5 into the bowl 31, the tighter the locking member 6 abuts against the ball head 4, thereby limiting the position of the ball head 4 and fixing the direction of the telescopic support rod 7. The bowl 31 has a concave cavity 33, and the ball head 4 is placed in the concave cavity 33, and the concave cavity 33 covers two-thirds of the surface area of ​​the ball head 4 to limit the ball head 4 from escaping from the concave cavity 33.

[0025] The support base of the wire drawing fixture is generally used to support the hardware processing part 8. The surface of the existing support base is mostly a flat structure and cannot adapt to the hardware processing part 8 with a curved surface. Even if the support base is provided with a bending part to adapt to the curved surface of the hardware processing part, this is a fixed structure and can only adapt to a single processing part, with poor application flexibility. Therefore, in this structure, a curved surface support assembly 2 is added to the support base. The curved surface support assembly 2 includes a support bowl 3, a ball head 4, a screw rod 5, a locking part 6, a telescopic support rod 7 and a top contact part 8; the telescopic support rod 7 can be rotated to change the angle, so as to adapt to the curved surface positions in multiple directions. At the same time, the telescopic support rod 7 can also be extended and adjusted to ensure that the telescopic support rod 7 can abut against the curved surface of the processing part; the top contact part 8 is threadedly connected to the telescopic rod and can be replaced at any time according to the curved surface of the processing part to ensure that it can adapt to contact the curved surface of the hardware processing part, making it more flexible and convenient to use.

The schematic description of the above terms in this specification does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0027] Through the description of the above structure and principle, those skilled in the art should understand that the present invention is not limited to the above specific implementation manners. The improvements and substitutions using the well-known technologies in the art based on the present invention fall within the protection scope of the present invention, which should be defined by each claim.
