Description

Technical Field

[0001] The utility model belongs to the technical field of marking equipment, and in particular relates to a positioning clamping mechanism and a marking equipment. Background Art

[0002] With the advancement of science and technology, coding machines are widely used in many industries, including manufacturing, pharmaceutical, food and beverage, electronics, etc., and provide high-quality services for high-quality, efficient and low-cost modern processing and production. For example, in the manufacturing industry, coding machines are used to engrave and mark various materials to improve the recognition and added value of products; in the pharmaceutical industry, coding machines mark drug packaging to ensure product traceability and authenticity; in the electronics industry, coding machines are used to mark various components of electronic products, providing permanent marking and anti-counterfeiting functions.

[0003] Moreover, with the continuous advancement of science and technology, marking machine technology is also constantly innovating. However, in actual application, the existing marking equipment usually relies on the two features of positioning holes and clamping holes on the workpiece to achieve the positioning and clamping of the workpiece; and in actual application, many workpieces only have positioning holes but not clamping holes. When marking such workpieces, the existing marking equipment cannot provide a stable clamping force by only using the positioning pin positioning method. Therefore, it often relies on the operator's hand-held during the entire marking process, which makes the entire marking process not only inefficient, but also unable to guarantee the stability and accuracy of the marking.

[0004] In addition, although some marking machines on the market have begun to be equipped with clamping mechanisms, the existing clamping mechanisms usually have problems of complex structure and high manufacturing cost, and they are often difficult to adapt to workpieces of different sizes and thicknesses.

At this time, when the utility model is used to position and clamp the workpiece placed on the workbench of the marking equipment, on the one hand, the workpiece can be positioned by the cooperation between the outer cylindrical surface of the clamping sleeve and the positioning hole set on the workpiece, and on the other hand, the clamping arm can be driven by the rotary drive component to rotate around the pin to clamp the workpiece between the gasket component and the clamping part, thereby realizing the integration of the clamping and positioning of the workpiece. At the same time, it can also meet the clamping requirements of different plate thicknesses by replacing gasket components of different thicknesses and clamping sleeves of different sizes, so that the utility model has the characteristics of strong design compatibility and scalability.

[0007] Furthermore, the middle part of the clamping arm is rotatably mounted inside the horizontal through hole through a pin shaft, and the upper part of the clamping arm is transmission-connected to the rotary drive assembly.

[0008] Furthermore, the rotary drive assembly includes a quick clamp installed on the upper part of the bracket and an arc groove arranged on the upper part of the clamping arm, the handle of the quick clamp is located outside the bracket, the movement direction of the power output end of the quick clamp is in the vertical direction, and a connecting pin is arranged at the lower part of the power output end of the quick clamp, the end of the connecting pin is slidably installed in the arc groove, and the arc groove and the clamping part are respectively arranged on both sides of the clamping arm. At this time, the up and down movement of the connecting pin can be realized by swinging the handle of the quick clamp, and the clamping arm is driven to rotate around the pin shaft through the cooperation between the connecting pin and the arc groove to clamp the workpiece.

[0009] Furthermore, the gasket assembly includes a gasket and at least one gasket, and the gasket and the gasket are installed in sequence from top to bottom under the connecting plate, and the number of gaskets can be flexibly selected according to the thickness of the workpiece so that it can meet the clamping requirements of different plate thicknesses and ensure that the utility model has the characteristics of design compatibility and strong scalability.

[0010] Furthermore, the pad is made of a soft material, such as a rubber material, a foam plastic material, or other conventional flexible material, so as to provide a certain degree of protection for the workpiece in contact with it and prevent the workpiece from being bumped.

[0011] Furthermore, a protective plate is provided on the outer side of the bracket, and various components installed in the bracket are protected by the protective plate to ensure the safety of use.

[0012] On the other hand, the utility model further provides a marking device, which includes a workbench, on which the positioning and clamping mechanism is installed, and the workpiece to be processed is positioned and clamped by the positioning and clamping mechanism.

[0013] It can be seen from the above technical scheme that the utility model has the following advantages: when the utility model is used to position and clamp a workpiece placed on the workbench of the marking equipment, on the one hand, the workpiece can be positioned by the cooperation between the outer cylindrical surface of the clamping sleeve and the positioning hole set on the workpiece, and on the other hand, the clamping arm can be driven to rotate around the pin shaft by the rotating drive assembly to clamp the workpiece between the gasket assembly and the clamping part, thereby realizing the integrated clamping and positioning of the workpiece.
