After the adoption of the mechanism, the universal cylindrical grinding machine can realize the adjustment of the feeding directions so as to realize beveling grinding.
Description
Technical field
The utility model is a kind of infeed mean of universal grinding machine external, refers in particular to the adjustable feed mechanism of a kind of direction of feed.
Background technology
The feed mechanism of universal grinding machine external is generally used for finishing the jumping into of hand feed, emery wheel of grinding and two functions such as jumps out.In order to satisfy above-mentioned requirements, this device should have the hand feed function, action such as can finish that emery wheel is jumped soon, and have higher repetitive positioning accuracy, locating speed and stationarity.But the feed mechanism of present common universal grinding machine external does not have the function of adjusting direction of feed, and it can not realize cutting sth. askew into grinding, promptly can not be implemented in the processing of finishing excircle of workpiece and shaft shoulder end face in angular plunge grinding yet.
Summary of the invention
The purpose of this utility model is to design a kind of feed mechanism of universal grinding machine external, adopt this mechanism after, can make universal grinding machine external realize the adjustment of direction of feed, and then realize cutting sth. askew into grinding.
Its main technical schemes is a connection half-nut below last planker, half-nut and screw mandrel match, one end of screw mandrel utilizes bearing to be connected with the piston rod of F.F. oil cylinder, the other end is connected with bevel pinion, last planker utilizes guide rail to be connected respectively with following planker, guide rail is parallel with screw mandrel, and following planker is connected on the base plate, and base plate is fixed on the lathe bed.
The end of screw mandrel is positioned at the internal splined hole of bevel pinion, end face at screw mandrel sets a screw, position corresponding to the dog screw of screw mandrel end on following planker is equipped with a dead block, between the mating surface of guide rail, needle roller is set, is provided for eliminating the elimination clearance mechanism of the fit clearance of screw mandrel and half-nut below the last planker.
Bevel pinion utilizes bearing to be installed in down on the planker, and bevel gear wheel is connected on the power transmission shaft, and power transmission shaft utilizes bearing to be installed on the centring sleeve, and centring sleeve utilizes transmission case to be fixed on the base plate, in the lower end of power transmission shaft worm gear is installed, and worm gear cooperates with worm screw.
The utility model has the advantages that the transmission that utilizes bevel-gear sett, unclamp the fixing screw of planker down, planker is rotated around centring sleeve on base plate, thereby can realize the change of direction of feed, can guarantee the normal delivery of hand feed campaign again; Adopt flat-V-type roller guide, can reduce wear, improve the rigidity of bearing capacity and this mechanism, improve its sensitivity simultaneously, thereby guarantee to have higher grinding accuracy; The dog screw that utilization is contained on the screw mandrel can be realized the location twice with the dead block that is contained in down on the planker, thereby improves the fast repetitive positioning accuracy of jumping; By bevel gear pair be contained in the worm screw in the transmission case, the transmission that worm gear pairs can be realized feed motion; After the F.F. oil cylinder with fast jumping effect has been installed on the screw mandrel, when both having guaranteed that oil cylinder was in the anteposition halted state, the feed motion of screw mandrel, when having guaranteed that again screw mandrel is not done feed motion, screw mandrel can utilize the F.F. oil cylinder to drive upward planker realization by half-nut and jump into fast.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
As shown in the figure: an end of screw mandrel 5 is connected with the piston rod 2 of F.F. oil cylinder 1 by bearing 4, and F.F. oil cylinder 1 links to each other with following planker 6; The other end of screw mandrel 5 is enclosed within the internal splined hole of bevel pinion 9, and its end face is equipped with a dog screw 13, and the dead block 14 of dog screw 13 on being contained in down planker 6 realized the location twice, to improve fast jumping repetitive positioning accuracy.Have plane and the V-type rail that matches respectively on last planker 3 and the following planker 6, be that the one side is to utilize the guide rail of plane contact, opposite side is the V-shaped guide rail of section, is called for short flat-V-type rail, needle roller 25,27 is set respectively between the mating surface of guide rail, and guide rail is parallel with screw mandrel 5.After in the mating surface of flat-V-type rail, being provided with needle roller 25,27, can improve the sliding mode of upper and lower carriage rail face, reduce this, and improve the stationarity of motion the wearing and tearing between friction pair.
Following planker 6 is fixed on the base plate 21, unclamps nut 24, and rotatable planker down is to adjust direction of feed; Base plate 21 usefulness T type screws 23 are fixed on the lathe bed 22.
Connection half-nut 7 below last planker 3, half-nut 7 matches with screw mandrel 5, also is equipped with in addition to eliminate clearance mechanism 26 below last planker 3, to improve the transmission accuracy of half-nut 7 and screw mandrel 5.
Bevel pinion 9 utilizes bearing 10 to be installed in down on the planker 6, makes screw mandrel 5 be the double base form, and higher rigidity is arranged; Bevel gear wheel 8 is connected on the power transmission shaft 15, and power transmission shaft 15 utilizes bearing 17 to be installed on the centring sleeve 16, and centring sleeve 16 is fixed on the base plate 21 by transmission case 20; Worm gear 19 also is connected on the power transmission shaft 15, and the hand feed campaign is delivered to earlier on the worm screw 18 that worm gear 19 matches.During work, the oil cylinder feeding is moved piston, drives screw mandrel 5 fast moving by piston rod 2, and at this moment, screw mandrel 5 should stop operating.When needs change direction of feed, only need unclamp nut 24, make down planker 6 rotate required angle around centring sleeve 16, fastening nut 24 can be realized the change of direction of feed again.11,12 are respectively bearing block and nut among Fig. 1.
