Embodiment Construction
[0011] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0012] The structure diagram of the present invention is as figure 2 shown. A weight compensation mechanism applied to the ram 2 of a milling and boring machine with an attachment 4 is characterized in that it includes a compensation oil chamber 3 . The compensation oil chamber 3 is located at the front end of the headstock 1 , that is, below the ram 2 . The front end of the ram 2 of the milling and boring machine where the weight compensation mechanism is located has an additional attachment 4, and the compensation oil chamber 3 provides a separate oil circuit through a servo proportional pressure reducing valve 31 to control the oil pressure ...

The invention relates to the technical field of milling and boring machines, and discloses a weight compensation mechanism applicable for added accessories on a milling and boring machine ram. The weight compensation mechanism is characterized in that the weight compensation mechanism comprises two groups of wire ropes, wire rope pulleys, a balance compensating cylinder and balance weights; the two groups of wire ropes include a group of balance compensating wire ropes and a group of gravity balancing wire ropes; the two groups of the wire ropes are installed at the upper parts of milling and boring machine columns through the wire rope pulleys, and one end of each wire rope is connected to the balance weight; the other end of each gravity balancing wire rope is connected to the rear part of a spindle box for bearing most weight of the spindle box; the gravity balancing wire ropes are connected to the front part of the spindle box through the balance compensating cylinder for compensation; and the balance compensating cylinder is provided with a servo proportional pressure reducing valve used for controlling oil pressure in the balance compensating cylinder. According to the weight compensation mechanism, through arranging a compensating oil chamber at the front end of the spindle box, namely below the ram, the problem of ram bowing caused by change in center of gravity after overhanging of the ram is solved.
Description
technical field [0001] The invention relates to the technical field of milling and boring machines, and more specifically, to a weight compensation mechanism applied to attachments for rams of milling and boring machines. Background technique [0002] For large machine tools such as milling and boring machines, in the process of running and cutting workpieces, the spindle box, ram, spindle and other components cause changes in the force system of the machine tool due to stress, and the machine tool components are caused by friction heat, cutting heat and environmental temperature changes. The thermal deformation that occurs will lead to changes in the relative position between machine tool components, destroying the accuracy of their relative motion, changing the geometric accuracy, control accuracy and machining accuracy of the machine tool, and ultimately reducing the overall performance of the machine tool. [0003] Analyze the deformation of the spindle box and ram of th...
