The testing device of the large-span machine tool guide rail protective cover is characterized in that an under carriage is included, a servo motor which is controlled through a controller is fixed in one side of the under carriage, a synchronous belt and a driving platform which move in the length direction of the under carriage are sequentially matched to be arranged on the servo motor, and guide rails which are matched with the testing protective cover to make reciprocating motion are fixed on the two sides in the width direction of the under carriage. The testing device of the large-span machine tool guide rail protective cover is unique in structure, short in testing period, reliable in testing and long in service life.
Description
Technical field
The present invention relates to a kind of test unit of machine tool guideway, especially relate to a kind of test unit of large span machine tool guide rail protective cover.
Background technology
China's machine industry was keeping higher boom in recent years, the industry size sustainable growth, and the output speedup is far above the mechanical industry average level.2010, in the situation that financial crisis all causes serious impact to global machine industry, the situation of raising after pressing down before China's machine industry but presents.Yet although China's machine industry is huge, and abroad compare, strong not enough.The general dependence on import of China's lathe, cause the import lathe constantly to enter in a large number home market, China's Machine Tool Development industry has been produced to greater impact, some heavy duty machine tools particularly, as the import unit prices such as gantry mill, gantry machining center, milling-boring machine, vertical lathe, numerical control gear machining tool drop, harsher competition has been caused in the heavy duty machine tools market that the market demand has been started to glide.Continue in addition a large amount of machining centers of import, the large wide machine tool product of numerically controlled lathe equivalent, to China's Machine Tool Enterprises carry out structural adjustment, industrial upgrading will cause long-term negative effect.
The large span of lathe is the inexorable trend of Machine Tool Development, the developing direction of modern machine is large span, at a high speed, accurate, compound, intelligence, environmental protection, one of functional part that protective cover is important as lathe, be hinder China NC Machine in, one of bottleneck of high-grade development, the developing direction of lathe main frame also is close in its development, also towards large span, at a high speed, low noise, long-life, save space and the energy, conform and require to wait to adapt to the development need of main frame, on technological layer, be mainly manifested in: maximize, high speed, movingization of combination, economized, environmental protection.It is reported, it is domestic that also not have now specialized factory to produce this be the supporting large span guide rail protection cover of machining center, the many dependence on import of domestic machine tool plant, the foreign side of Chinese-foreign joint machine tool plant is also many using this protective cover as more crucial technology and parts, by foreign side, is directly provided.In order to produce the protective cover that meets above-mentioned requirements, detect its performance thereby at first need protective cover to producing to be tested, reach request for utilization, and also do not solve the test unit of problems at present.
Summary of the invention
The objective of the invention is to overcome the defect of prior art, provide that a kind of structure is unique, experimental period is short, experiment is reliable, the test unit of a kind of large span machine tool guide rail protective cover of long service life.
The present invention realizes in the following way:
A kind of test unit of large span machine tool guide rail protective cover, it is characterized in that: it comprises underframe, be fixed with the servomotor of controlling by controller in underframe one side, be combined with successively the Timing Belt moved along above-mentioned length over end sills direction on servomotor and drive platform, in the both sides of above-mentioned width over side sills direction, being fixed with the guide rail that the compatibility test guard shield moves back and forth;
Described Timing Belt coordinates with described servomotor by bearing;
Described bearing is linear bearing.
The present invention has following effect:
1) structure uniqueness: it comprises underframe protective cover test unit provided by the invention, be fixed with the servomotor of controlling by controller in underframe one side, be combined with successively the Timing Belt moved along above-mentioned length over end sills direction on servomotor and drive platform, in the both sides of above-mentioned width over side sills direction, being fixed with the guide rail that the compatibility test guard shield moves back and forth; According to the stroke of guide rail protection cover, the load-carrying size is selected linear bearing and motor.Linear bearing is a kind of linear motion system with low-cost production, for unlimited stroke and cylinder axis, is used in conjunction with.Because being, bearing ball and axle contact, therefore maneuvering load is little.Steel ball rotates with minimum frictional resistance, thereby can obtain high-speed, high-precision easy motion, and the simulation guide rail protection covers on the effect of actual motion in lathe; Design applicable support frame structure, supporting construction is divided into five parts: base, fixed mount, driving platform, motor cabinet, guide rail.Base is selected applicable section bar and rational welding technology and is guaranteed its intensity.Drive platform to be connected with the guide rail protection cover of test, the principle of work of simulated machine tool machining center is tested together with making it and driving platform in high-speed motion; During according to large span machine tool movement, start and brake and all need larger power, but need high-level positioning precision, so select a day intrinsic safety river motion controller MP2300, by setting parameter, thereby controller accurately transfers to its signal the motion state of the accurate Control experiment platform of motor driver.
2) experimental period is short: it is easy, simple for production, with short production cycle that experimental provision provided by the invention is implemented, and can directly apply to experiment table after new product development and be tested, and saved for nearly 1/2 proving time.
3) experiment is reliable: the product of experimental provision provided by the invention after checking, can be in the situation that analog operation, find the deficiency in some designs, the problems such as the shock there will be up and down as large span lathe, not parallel, interference, thus provide material for research of technique.
4) serviceable life: the way-cover of device experimental verification provided by the invention should be not less than 500,000 times in the specified trouble free service life-span with when operation under line speed, reciprocating stroke.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of test unit of large span machine tool guide rail protective cover, as shown in Figure 1: it comprises underframe 1, be fixed with the servomotor 4 of controlling by controller 5 in underframe 1 one sides, be combined with successively the Timing Belt 6 moved along above-mentioned underframe 1 length direction on servomotor 4 and drive platform 2, in the both sides of above-mentioned underframe 1 Width, being fixed with the guide rail 3 that the compatibility test guard shield moves back and forth;
Described Timing Belt 6 coordinates with described servomotor 4 by bearing;
Described bearing is linear bearing.
During test, will drive platform 2 to be connected with the guide rail protection cover that will test, the principle of work of simulated machine tool machining center, make it and test in large span situation together with driving platform, controller 5 is passed through to setting parameter, thereby controller 5 accurately transfers to the accurate Control experiment platform motion state of servomotor 4 drivers by its signal, the novel lathe guide rail protection cover that design has been produced is installed in experiment table setup parameter as the stability of speed, stroke, its motion of time verifying.
