Detailed description of the invention
See Fig. 1-5, the utility model discloses a kind of major diameter on-line measurement driver train (hereinafter referred to as driver train), comprise the gear cluster be made up of the multiple gears be fixedly mounted on same gear wheel shaft and the first tooth bar 3 and the second tooth bar 5 be meshed respectively with at least two gears in this gear cluster, described first tooth bar and the second tooth bar antarafacial are arranged vertically, and are realized the conversion of the first tooth bar and the second tooth bar straight-line motion on perpendicular direction by gear wheel shaft 4.First tooth bar drives it to do synchronous straight reciprocating motion by a linear drive apparatus, second tooth bar is fixedly connected with the gauge head fixed mount installed for gauge head, for driving advance, the retrogressing of gauge head fixed mount, gauge head fixed mount is fixedly mounted on the slide block 61 of line slideway 6.Described gear wheel shaft can only have above-mentioned two gears, also can arrange other gears in addition, and these other gears can be meshed with the second tooth bar, as equipment gear, by arranging the different numbers of teeth, realizes different transmitting ratios.
Described driver train adopts line slideway as guide piece, ensured feeding and the positioning precision of measurement mechanism by the guiding accuracy of line slideway, avoid existing measurement mechanism well and rely on round guide rod to add instability problem in the gauge head feeding process caused by guiding driving oil cylinder.
Described driver train can be directly installed on platen 9, and track 62 needs of line slideway are fixedly mounted on described platen.Each gear of gear cluster is fixed as one each via the gear wheel shaft of key connecting and gear cluster, and the gear wheel shaft of gear cluster is rotaryed connection with described platen, and gear wheel shaft axis is vertical with track installation face.
Certainly, described driver train can also comprise pedestal 1, and correspondingly, the track of described line slideway is fixedly mounted on described pedestal, and described pedestal is then fixedly mounted on described platen.The gear wheel shaft of described gear cluster is preferably rotaryed connection with described pedestal, and gear wheel shaft axis is vertical with track installation face.
Described linear drive apparatus preferably adopts hydraulic ram 2, and the cylinder body of hydraulic ram is fixed on pedestal, and the first tooth bar is fixedly connected on the piston rod (or claiming guide rod) of described hydraulic ram.Described hydraulic ram and the first tooth bar are arranged in parallel.As the concrete connection mode citing of one, described first tooth bar is connected with the overhanging end winding support of hydraulic cylinder piston rod by the L shape structure of its one end.
Described gauge head fixed mount comprises base and is fixed on the support 7 on base, and described support can be shaft-like, and support is vertically fixed on base, and on support, differing heights place is provided with gauge head mount pad/mounting hole separately, in order to meet the installation needs of gauge head differing heights.Adopt paired gauge head in diameter on-line measurement device, this paired gauge head is arranged on support one on the other, and the distance between two gauge heads depends on the diameter of workpiece.
When diameter of work is larger, described gauge head fixed mount can also comprise paired auxiliary stand 8, and described auxiliary stand is also in shaft-like, and on auxiliary stand, differing heights place is also provided with gauge head mount pad/mounting hole separately.Described auxiliary stand is fixed on the bracket one on the other separately, and on the side being fixed on described support and respectively to top and bottom (as shown in Figure 3) that are upper, that exceed described support downwards, distance between two gauge heads installed in order to expansion, thus meet the on-line measurement requirement of larger diameter workpiece, realize larger measurement range.
As further optimal technical scheme, more compared with the number of teeth of all the other gears with the number of teeth of the second tooth bar gears in mesh in described driver train.Ratio of number of teeth between the two for 2:1,3:1,4:1 or can become other any ratios according to the diameter design of workpiece, achieve the stroke ratio being greater than 1:1 of gauge head and hydraulic ram, compared to the stroke ratio of the 1:1 of existing on-line measurement device, even if adopt the utility model to need larger gauge head stroke because measuring larger diameter workpiece, also be unlikely to the hydraulic ram causing adopting larger row journey, therefore also do not need significantly to increase taking up room of hydraulic ram.
Described pedestal comprises Base body and auxiliary fixed block 11, Base body is roughly in bar shaped platy structure, the front end of described Base body is provided with the hook shape projection 12 to downward-extension, from front end, a distance is provided with to downward-extension straight protruding 13 to the back-end, and this distance can be about 1/3 of Base body total length.The overbending direction hooking the hook portion of shape projection towards rear end, for catching on the corresponding construction on platen.The inner side plane hooking shape projection and straight projection and the lower plane being positioned at Base body are therebetween the mounting plane of pedestal, for fitting to the corresponding mounting plane on platen and locate.Described auxiliary fixed block Main Function realizes pedestal fixing on platen, and its cross-sectional plane is L-shaped, and claim it to be provided with two perpendicular limbs here, the end face of a limb is provided with tapped blind hole.In order to pedestal is fixed on platen, first to hook with screw precession in the tapped bore of shape projection and screw be against and hook in bench board respective planes that the protruding medial surface of shape fits, the medial surface of straight projection and bench board respective planes is made to fit tightly location, then with bolt through the counterbore in straight projection and precession assists the tapped blind hole on fixed block to make straight projection be connected and fixed to the corresponding limb of auxiliary fixed block, utilize the appropriate section of assisting another limb of fixed block to catch on platen.The position that auxiliary fixed block and platen respective planes should be fitted and cannot be fitted can by arranging the realizations such as pad.Adopt the pedestal of above-mentioned Split type structure, the working accuracy of each locating surface easily ensures, and is easy to its location and fixes.
The part at described Base body rear portion about 2/3 is overhung at outside platen.Track is fixed on above Base body rear portion, and described gauge head fixed mount is positioned at the top of pedestal, and described hydraulic ram and the first tooth bar are positioned at the below at overhanging part base (i.e. Base body rear portion).Be positioned at the top of pedestal with the second tooth bar gears in mesh, and all the other gears are positioned at the below of pedestal.
As shown in Figure 5, the basic functional principle of described driver train is: driven the first tooth bar to advance by the advance of hydraulic ram, fallback synchronization, retreated.First tooth bar is rotary motion by being meshed the transform linear motion of the first tooth bar with the gear of in all the other gears, the each gear of gear cluster synchronous rotary thereupon, and then the straight-line motion by the engagement of the second rack and pinion by the convert rotational motion of gear being the second tooth bar.Because the first tooth bar and the second tooth bar antarafacial are arranged vertically, gear cluster and the first tooth bar, two complete the right-angled crossing conversion of mode of motion, and namely the hydraulic oil cylinder driving of Z-direction is transformed into the measurement mechanism feed motion of X-direction.Due to many compared with the number of teeth of all the other gears with the number of teeth of the second tooth bar gears in mesh, therefore above-mentioned conversion also achieve simultaneously lower linear velocity to the conversion of higher line speed and compared with short travel to the conversion compared with Long travel.
The exploitation of driver train principle of work of the present utility model to other automatic on-line measurement actuating devices has inspiration meaning.
