Description

Accurate positioning mechanism of numerical control mortising machine

Technical Field

The utility model relates to the technical field of mortising processing equipment, in particular to a precise positioning mechanism of a numerical control mortising machine.

Background

In the process of manufacturing the wood product, due to the special physical properties of the wood, the wood product cannot be shaped by materials such as iron, plastics and the like, but can be formed by mutually splicing a plurality of pieces of wood. Specifically, when the timber is spliced, the connection modes such as mortise and tenon are often selected for carrying out. Although, there is a simpler way of assembly using nails for the connection; however, on the one hand, the iron nails are easy to rust due to the oxidation of metal, so that the connection is invalid; on the other hand, after the iron nails are nailed into the timber, irreversible damage can be caused to the timber, so that the secondary recycling of the timber is affected after the timber with the iron nails is scrapped. In addition, when wooden products are operated in mortise and tenon modes, punching is often required; nowadays, the precision requirements for the products themselves are increasing due to the advent of various new materials. The wooden product cannot be shaped, so that the accuracy of the wooden product such as a plastic product or a metal product cannot be achieved; therefore, the hole site can be precisely controlled only when the splicing process is performed, so that the precision of the product is ensured.

Thus, mortises have been created; the mortising machine is a woodworking machine tool for processing rectangular mortises or waist round mortises on timber. In the existing production process of wood products, the punching process is often carried out through a manual woodworking mortising machine, and when the manual woodworking mortising machine punches holes, a worker needs to judge through eye force. The mode is easy to be interfered by the outside, such as light, manual error and the like, and the defects of low working efficiency, low positioning precision, poor consistency and the like are easily caused.

Based on the above, chinese patent CN104858946a discloses a woodworking mortising machine, which comprises a frame, a transverse and longitudinal device is arranged on the frame, and a workbench and a perforating machine are respectively arranged on the transverse and longitudinal device; the transverse device is provided with a transverse movement sensing device, and the transverse movement sensing device comprises a limit switch and a slit switch; the longitudinal device is provided with a longitudinal movement sensing device which is a proximity switch.

However, the woodworking mortising machine disclosed in the above description has the technical problem of inaccurate machining positioning. Specifically, the positioning mechanism of the woodworking mortising machine is arranged in the following manner: the workbench comprises a support on the table surface of the workbench, and a clamping cylinder is arranged on the support. The output shaft of the clamping cylinder penetrates through the bracket and then is provided with a push plate. The workbench is provided with a corresponding baffle corresponding to the push plate; the wood block can be clamped through the corresponding actions of the push plate and the baffle plate. However, in actual production practice, it has been found that materials positioned solely by the relative clamping action of the pusher and the flapper are prone to sloshing, tipping and misalignment. For example, in the current material processing requirements, round bar wood or polygonal wood is common, and the wood is difficult to firmly position by two clamping plates; the phenomenon of inaccurate positioning occurs when the mortises are formed; even if the wood is positioned effectively during the cutting operation, the positioning deviation is liable to occur due to the shaking during the processing or the cutting operation.
