Description

Novel marking machine

Technical Field

The invention belongs to the technical field of marking machines, and particularly relates to a marking machine suitable for marking the surface of a large cylindrical workpiece.

Background

The marking machine comprises a marking needle assembly, a control part of the marking needle assembly, and a workpiece mounting, bearing and rotating control part. Because the transmission mechanism transmits the torque to the working disc bearing the workpiece in a worm gear manner through the central part of the lower end of the transmission connecting shaft, the requirement cannot be met when a large workpiece has a large torque operation requirement, and the power of the motor is increased to bring waste.

Disclosure of Invention

The novel marking machine is provided for solving the technical problems.

The technical means adopted by the invention for solving the technical problems is to invent a novel marking machine, which comprises a lower workbench, a marking needle assembly and a control part thereof, wherein the marking needle assembly is positioned on the left side of the upper part of the workbench, and the control part is used for mounting, bearing and rotating the workpiece on the right side. The working disc for placing the workpiece is driven by a lower transmission mechanism of the working disc, and the transmission mechanism comprises a transmission connecting shaft, a driven end large gear, a driving end small gear and a motor speed reducer assembly, wherein the lower part of the center of the working disc is directly and fixedly connected with the transmission connecting shaft, the driven end large gear is arranged at the lower part of the transmission connecting shaft, the driving end small gear is meshed with the driven end large gear, and the motor speed reducer. The improvement not only changes the single-stage reduction transmission of the prior art into the two-stage reduction transmission to greatly increase the torque output, but also directly installs the driven bull gear at the lower part of the transmission connecting shaft, and the distance between the meshing point and the rotation center is large, thereby being more beneficial to improving the torque. In order to solve the inertia clearance generated by the rotation in the positive and negative directions, a damping mechanism is arranged at the lower part of the working disc close to the outer edge for eliminating. In order to ensure the bearing capacity and the stability of rotation, a thrust bearing is arranged between the working disc and a supporting disc at the lower part of the working disc, a taper thrust bearing is arranged between the transmission connecting shaft and the supporting disc, and the supporting disc is fixed on the working table through a supporting column.

The workpiece mounting, bearing and rotation control part has the function of circular motion automatic indexing and is realized by matching a working disc, a supporting disc, a transmission mechanism and other parts.

The marking needle assembly can perform linear motion in the X direction and the Y direction on the vertical plane of the marking needle assembly by virtue of an X-direction motor and a Y-direction motor; the marking needle assembly can also be lifted and lowered together with the marking device by virtue of a lifting hand wheel through a lifting mechanism, and the distance between the marking needle assembly and a workpiece can be adjusted by virtue of a radial hand wheel.

During operation, lay the cylinder work piece on the working disc, adjust the mark needle position of beating mark needle subassembly 5 through lifting hand wheel and radial hand wheel, make the surface of work piece beat the printing work within range of marking the needle head, start motor speed reducer subassembly. The automatic indexing mechanism has the function of circular motion, so that the surface of a workpiece in the rotating process of the workpiece can be divided into a plurality of sections according to a set program, and then each section is marked. The surface of each section can be regarded as an approximate plane, the marking needle can mark the surface within 5 mm of concave-convex range by means of the elastic piece arranged on the rear seat of the marking needle, and the work can be completed by a computer software program.

As a further development of the invention, the transmission mechanism can also be used in another way as follows: the lower part of the outer edge of the working disc is provided with a driven inner gear ring which is meshed with a pinion arranged at the output end of the motor speed reducer assembly, and other components and functions are the same, so that the effect of improving the output torque by half effort can be achieved.

The invention has the beneficial effect that the rotation performance of the work disc for bearing the workpiece is greatly improved through the improvement of the transmission mechanism. When the torque is increased, the reasonable design of the transmission mechanism is utilized, compared with the prior art, the electric energy is saved, the motor cost is saved, and the product running performance is more reliable and stable.
