A kind of numerical control machine slide rail safeguard structure
Technical field
The utility model relates to the protection of numerical control machine slide rail.Especially be applied to oblique lathe bed numerically controlled lathe A type main spindle box Z axis rail protection and leading screw protection.
Background technology
When numerically controlled lathe is worked, have cutting fluid, the iron filings lathe rear portion of flying to, the Z-direction guide rail of existing lathe has the lower-left protective cover that is installed in the cross slid platform left side, by the move left and right of cross slid platform, drives the bottom that it penetrates main spindle box.Other has the lower-left scraper plate that is installed on the main spindle box dividing plate to cooperate this lower-left protective cover to scrape bits when mobile, prevents that cutting fluid, iron filings etc. from entering lathe.But because main spindle box is A type structure, two tie point is separately fixed at lathe bed top and bottom, the tie point that wherein is fixed on the lathe bed bottom is unaffected, and just in time having hindered baffle plate, passes the tie point that is fixed on lathe bed top, because machine tool chief axis runs up and makes cutting fluid, splash at a high speed around the iron filings, therefore the tie point place on main spindle box top still has more cutting fluid, iron filings etc. fly into the lathe rear portion, thereby make cable, electric machine joints etc. are subjected to contamination wear easily, cause short circuit, faults such as damage, the lathe rear portion is leaked flow to ground, polluted working environment.
Summary of the invention
The purpose of this utility model provides a kind of numerical control machine slide rail safeguard structure, at the protection of A type main spindle box top tie point part, has further strengthened the protection to iron filings and cutting fluid especially, has avoided the iron filings cutting fluid to enter lathe.
Numerical control machine slide rail safeguard structure described in the utility model, comprise the lower-left protective cover that is fixed on the cross slid platform left side, lower-left scraper plate on the main spindle box dividing plate, protective cover in the left side is arranged above the protective cover of lower-left, be fixed on lathe top and main spindle box top tie point and be in same horizontal level, the protective cover top has left middle scraper to be fixed on the left side of cross slid platform in the left side, upper left protective cover is fixed on the cross slid platform upper left side, right protective cover is fixed on the cross slid platform right side, upper left protective cover links to each other with right protective cover, and the upper left scraper plate of upper left protective cover top is fixed on the main spindle box dividing plate.
Lower-left protective cover (4) top margin encases the base of protective cover in the left side (7) in the lining, makes its base outside, and protective cover in the left side (7) top margin encases the base of upper left protective cover (9) in the lining, makes its base outside.
Numerical control machine slide rail safeguard structure described in the utility model, because the lathe bed at tie point place has been fixed protective cover in the left side above main spindle box, and it scrapes the left middle scraper of bits to be fixed on the cooperation of cross slid platform left side, the cutting fluid, the iron filings that the obstruction baffle plate are passed the zone also protect, and have solved the problem of the integral protection that uses A type main shaft boxcar Z-direction guide rail.Because the location conflicts of main spindle box upper fixed tie point, and be divided into protective plate fixing and movable part protects, reach the purpose of integral protection.Realized the omnibearing safeguard function of lathe veritably, prevented iron filings and the cutting fluid lathe rear portion of flying to, its door has all been stayed in the machining area, zones such as machine tooling zone and Machine Tool Electric Appliance parts have been separated.
Description of drawings
Fig. 1 is for removing the main mechanical parts installation diagram of lathe of lathe protection, guide rail protection.
Fig. 2 is for installing the right lateral view of the protection of Z-direction guide rail and the protection of part lathe.
Fig. 3 is for installing the left lateral view of the protection of Z-direction guide rail and the protection of part lathe.
The specific embodiment
As Fig. 1-3, on the lathe bed 1, main spindle box 2 has been installed in the left side, and main spindle box 2 is A type structure, and bipod is contained in lathe bed top and bottom, and the centre is emptied, and can pass through the guide rail protector.
Be fixed on the lower-left protective cover 4 in cross slid platform 3 left sides, there is protective cover 7 in the left side its top, protective cover 7 bases are encased by lower-left protective cover 4 in the left side, be fixed on lathe bed 1 top, just with the tie point of main spindle box 2 upper fixed on same horizontal level, the left middle scraper 8 that cooperates protective cover 7 in the left side to scrape bits is installed in cross slid platform 3 left sides, has solved A type main spindle box top tie point and has hindered the problem that protective cover passes.
Upper left protective cover 9 is installed in cross slid platform 3 upper left sides, links to each other with right protective cover 10, and right protective cover 10 is installed in cross slid platform 3 right parts, and the three is connected.By the move left and right of cross slid platform 3, drive the upper left protective cover 9 of guide rail and above main spindle box 2, pass through.Cooperate the effects such as bits function, realization protection lathe rear cable and X-direction motor of scraping of the upper left scraper plate 11 that is contained on the main spindle box dividing plate 5.
Lower-left protective cover 4, upper left protective cover 9, left middle scraper 8, right protective cover 10 are fixed on cross slid platform 3 one, what protective cover 7, main spindle box dividing plate 5, main spindle box 2, lathe bed 1 etc. moved in lower-left scraper plate 6, upper left scraper plate 11, the left side relatively.Be about to left protective cover and make three sections of upper, middle and lowers, interlude is because the location conflicts of main spindle box 2, and is divided into protective plate fixing and movable part protects, and reaches the purpose of integral protection.
