A fixture for small disc parts used for mechanical dotting and marking

Abstract

The invention discloses a small-wafer type part clamp for mechanical dotting marking. The small-wafer type part clamp comprises a base, a pressure block, a slide block, a connecting rod and a connecting rod fixing block. One end of the upper portion of the base is provided with a dovetail slot, the two sides, which are close to the base, of the dovetail slot are provided with threaded openings, the center line of the dovetail slot is parallel to the center line of the base, the connecting rod fixing block is disposed at the end portion of the dovetail groove, the connecting rod fixation block is fixedly connected with the base through a bolt, an axial circular hole is arranged in the middle of the slide block, an axial threaded opening is arranged below the circular hole and is disposed at the same vertical plane, the slide block is installed at a side surface, which is disposed on the connecting rod fixing block, in the dovetail slot, a cone-end screw is screwed into a slide block threaded opening, a handle is fixedly connected with the connecting rod, and the connecting rod passes through the connecting rod fixing block to be fixedly connected with the slide block and drives the slide block and the cone-end screw to move. According to the invention, the clamp employs three-point type positioning, limits the freedom degree of each direction, performs good clamping positioning on small wafers in a mechanical dotting marking process, ensures the stability of the clamp in the marking process, effectively prevents vibration and interference, and guarantees the marking quality.

Description

technical field [0001] The invention relates to a clamping device in a mechanical marking process, in particular to a fixture for small disc parts used for mechanical dotting and marking. Background technique [0002] Marking the Data Matrix two-dimensional barcode directly on the surface of the marking object is the basis for realizing the information tracking and full life cycle management of the marking object, and is the key to improving the efficiency of inventory management and realizing the information collection and real-time tracking of the production process. [0003] At present, there are many fixture structures used for marking electronic products, nameplates and other commodities, and most of them are targeted special fixtures. In the patent CN202782199U, a marking tool for the gear shaft is described; in the patent CN203093341U, an automatic flip laser marking tool is disclosed; in the "Handbook of Fixture Structure Design" (page 37), a Screw type single point...

Problems solved by technology

However, in the existing fixtures, such as bolt-press plate combination fixtures, often due to their large size, they easily interfere with the marking needles of the mechanical dotting and marking machine, and cannot perform normal marking.

[0006] 3. For most of the fixtures, due to the complex structure, too many clamping parts or too large volume, the operation is complicated and the disassembly is inconvenient during the clamping and loosening process of the parts, which greatly reduces the production efficiency
