Description

Carving mills feeding mechanism of machine

Technical Field

The invention belongs to the technical field of machining equipment, relates to a carving and milling machine, and particularly relates to a feeding mechanism of the carving and milling machine.

Background

The workpiece processing engraving and milling machine has a plurality of models, and the basic structure is that a movable or unmovable workbench is arranged on a rack, a plurality of groups of rotatable clamping assemblies used for clamping workpieces are arranged on the workbench, the common clamping assemblies are rotary tables and tops, a plurality of movable engraving cutter heads are arranged on the workbench, the clamping assemblies rotate during processing, and each engraving cutter head corresponds to one group of clamping assemblies for engraving. Engraving and milling machines of this type are generally used for engraving pieces of a certain length, such as wood strips. Because some carves the outer peripheral face that needs processing the stuff, so need the centre gripping stuff tip to realize processing, this characteristic leads to ordinary being used for processing the plank or be used for processing the feeder mechanism of stuff tip all can't be suitable for, can't realize auxiliary positioning in the course of working promptly to the structure that utilizes the conveyer belt conveying from the front also can't be suitable for. Generally, the material is manually fed and placed, the clamping assembly is used for clamping two ends of a batten, and the batten is manually taken out and placed at the next station after being processed.

For example, patent No. 201710414425.0 discloses an engraving and milling machine, which comprises a frame and a beam, wherein the frame is provided with two support rods arranged along the longitudinal direction, a plurality of groups of clamping components are arranged between the two support rods along the transverse direction, each clamping component comprises a claw disc and a tip, the claw discs are arranged at the front end of the frame along the transverse direction, the tips are arranged at the rear end of the frame along the transverse direction, and the claw discs and the tips are in one-to-one correspondence and used for clamping and positioning cylindrical workpieces. The carving and milling machine also realizes subsequent carving by utilizing manual discharging. But manual operation is slow in overall efficiency and poor in placement accuracy. The workpiece is not easy to clamp the clamping assembly, clamping deviation often occurs, the shaft axis of the clamped workpiece deviates from the shaft axis of the clamping assembly, clamping precision is reduced, and dislocation of the carving position and reduction of carving precision are further influenced. If round battens are machined, the rotation center can be determined again to be the machining reference by utilizing the rotation characteristic, the machining precision is ensured, more blank allowance is required, a lot of materials are wasted, and machining is inaccurate if the allowance is small. If square battens are to be machined or other non-rotary machining is to be carried out, the machining foundation is not determined again, and only the reference in the initial feeding process is taken as the premise, so that the low precision is directly caused in the machining process.

to the existence of above-mentioned problem, the mode that improves efficiency that technical personnel in the field thought of easily is exactly to adopt the manipulator to snatch timber and transfer and place, though the manipulator can realize that automatic operation realizes about from top to bottom multi-dimensional motion and compare in artifical the improvement that has realized the precision, but because the direction that needs the motion is many, in case the parallel just need set up multiunit manipulator and take place to interfere with other parts such as centre gripping subassembly easily in multiunit station, the space that so needs is big, and the direction that simultaneously needs to compromise is many so each position all probably have the cooperation error, influence follow-up stability and precision easily. Or a limit stopper is added for the purpose of improving accuracy, as easily understood by those skilled in the art, as shown in patent No. 201910545596.6, but the structure still only can be matched with manual feeding, which is very disadvantageous in improving efficiency.
