Protective cover for machining platform

Abstract

The invention discloses a protective cover for a machining platform, which comprises two positioning plates respectively mounted on two sides of the machining platform, and protective mechanisms are arranged on the two positioning plates, so that dust and abrasive particles are prevented from being adhered to the surface of a lead screw for driving the machining platform through the protective mechanisms, and the normal work of the machining platform is further ensured; the protection mechanism comprises a mounting plate mounted at the end of the numerical control machine tool, a protection plate is arranged on the mounting plate, a plurality of protection units which are sequentially connected in a sliding and sleeving mode are arranged between the protection plate and the positioning plate, connecting plates are arranged in the middles of the protection units, and synchronous parts are further arranged on the connecting plates. Different from the prior art, when the machining platform works, the lead screw is protected, the connecting plate can be detached when the lead screw is checked, the whole protective cover is prevented from being detached, and it is guaranteed that the multiple protective units can be normally unfolded and closed through the mounting assemblies.

Description

technical field [0001] The invention relates to the technical field of protective appliances for machining centers, in particular to a protective cover for a machining platform. Background technique [0002] Machining center refers to a CNC machine tool equipped with a tool magazine, with automatic tool change function, and multi-process processing after clamping the workpiece at one time. The machining center is a highly mechatronic product. After the workpiece is clamped, the CNC system can control the machine tool to press Automatic selection and replacement of tools in different processes, automatic tool setting, automatic change of spindle speed, feed, etc., can continuously complete various processes such as drilling, boring, milling, reaming, tapping, etc., thus greatly reducing workpiece clamping time, measurement Auxiliary process time such as machine tool adjustment and other auxiliary process time, the processing shape is more complex, the precision is high, and t...

Problems solved by technology

[0003] However, we found in actual use that the protective cover of the machining center needs daily maintenance, and it is necessary to check whether the running track meets the lubrication requirements every day to prevent The damage caused by the huge friction caused by insufficiency, followed by the need to regularly check the shaft of the protective cover of the machining center, so as to prevent dust and abrasive particles from sticking to the surface of the lead screw, resulting in unqualified products, affecting the service life and work of the lead screw accuracy, and when checking the shaft and lead screw of the protective cover, it is often necessary to remove the protective cover as a whole to observe the internal situation. However, when the protective cover is installed, installation and debugging are required to ensure smooth operation and low noise. Small, it will not produce vibration and noise even in high-speed machine tool movement, so it greatly increases the workload of the operator, and if it is not checked, it will gradually affect the service life and accuracy of the screw. For this reason, we propose a Protective cover for processing platform
