The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model mechanism is as shown in Fig. 1,2,3,4,5, a kind of Z axis ram gib motion structure, comprise ram casing 1, slide casing 2, screw 5, it is characterized in that: the middle front part of ram casing 1 is socketed on slide casing 2, line slideway 4 is fixedly connected on the postmedian of slide casing 2 by screw 5, straight-line guide rail slide block 8 is fixed on the rear portion of ram casing 1 by screw 5, line slideway 4 is the line slideway assembly with straight-line guide rail slide block 8; Roller scroll box bearing 7 is fixed on the downside of slide casing 2 hole front ends by screw 5, roller scroll box 3 is fixed on roller scroll box bearing 7 by screw 5, roller scroll box 3 joins with ram casing 1 lower end, the both sides of slide casing 2 rear ends, hole respectively are provided with the structure that ram casing 1, slide casing 2, roller scroll box 3, screw 5, roller scroll box bearing 7 match, roller scroll box wedge 9 is limited in the upside of slide casing 2 front ends by screw 5, roller scroll box 3 is fixedly connected on roller scroll box wedge 9 by screw 5.According to described Z axis ram gib motion structure, it is characterized in that: the front end of described ram casing 1 is provided with main shaft inspection rod 10, and line slideway 4 is the line slideway assembly with straight-line guide rail slide block 8.According to described Z axis ram gib motion structure, it is characterized in that: be equipped with between described line slideway 4 and slide casing 2 and adjust backing plate 6.
use principle of the present utility model as shown in Figure 1, the utility model basic function---the implementation method of ram Z axis motion auto-compensation: the guide supporting part of the utility model Z axis ram movement comprises roller scroll box 3, line slideway 4, do forward at ram casing 1 and stretch out when motion, along with ram casing 1 extension elongation is elongated gradually, deadweight and rigidity reason due to the ram casing, ram casing 1 can produce nature and be bent downwardly distortion, namely can produce sagging, thereby affect the kinematic accuracy of Z axis ram, this deformation values can be crossed the main shaft inspection rod 10 of ram casing 1 end installation and measure.This structure is equipped with again straight-line guide rail slide block 8 at ram casing rear portion, straight-line guide rail slide block 8 can carry out rectilinear motion along line slideway 4, be equipped with between line slideway 4 and slide casing 2 and adjust backing plate 6, data according to 10 measurements of main shaft inspection rod, adjust the gauge of backing plate 6 by match grinding, make 8 pairs of ram casings of straight-line guide rail slide block 1 produce the trend that pulls down, thereby realize the auto-compensation to 1 distortion of ram casing.Wherein line slideway 4 and straight-line guide rail slide block 8 are on same straight line, can keep like this ram casing 1 to stretch out motion along linear running, keep the stable of accuracy.
The utility model utilizes a kind of Z axis ram gib motion structure, and this structure can realize effectively that the distortion that horizontal Machining centers is caused carries out auto-compensation, thereby improves the precision of lathe Z axis motion.
Embodiment recited above is described preferred embodiment of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model all should fall into protection domain of the present utility model.
