In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: processing slim shaft device on a kind of lathe, comprise base plate, on described base plate, slide and be provided with tool rest bracket and support portion base, on described base plate, be fixedly connected with first tooth bar, described first tooth bar engagement fit is connected with A gear, described A gear engagement fit is connected with second gear, described second gear engagement fit is connected with second tooth bar, described second tooth bar is fixedly connected on the base of described support portion, on the base of described support portion, be provided with spring portion, in described spring portion, slide and be provided with support portion, on described support portion, roll and be provided with roller, below, described support portion is provided with first butt hook, in described spring portion, be provided with second butt hook, between described first butt hook and described second butt hook, be provided with spring, on described tool rest bracket, be provided with knife rest, on described knife rest, be provided with cutter.
Described cutter and described roller are symmetrical in the both sides of axis setting and the described axis of scroll chuck, and described A gear is all consistent with described second tooth bar specifications parameter.
Described base plate can slide by the described axis direction along described scroll chuck on lathe.
The utility model has solved the problem of slender axles poor rigidity in process, the higher defect of percent defective of processing slim axle in prior art in solution prior art, realize the percent defective that reduces processing slim axle, there is high accuracy, high efficiency advantage, also there is the function to the positioning and clamping of the slender axles of various diameters, increased the versatility of equipment.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model support portion schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: as shown in Figure 1 to Figure 2, processing slim shaft device on a kind of lathe, comprise base plate 1, on described base plate 1, slide and be provided with tool rest bracket 2 and support portion base 4, on described base plate 1, be fixedly connected with first tooth bar 11, described first tooth bar 11 engagement fit are connected with A gear 21, described A gear 21 engagement fit are connected with second gear 22, described second gear 22 engagement fit are connected with second tooth bar 41, described second tooth bar 41 is fixedly connected on described support portion base 4, on described support portion base 4, be provided with spring portion 42, in described spring portion 42, slide and be provided with support portion 5, on described support portion 5, roll and be provided with roller 51, 5 belows, described support portion are provided with first butt hook 52, in described spring portion 42, be provided with second butt hook 43, between described first butt hook 52 and described second butt hook 43, be provided with spring 53, on described tool rest bracket 2, be provided with knife rest 3, on described knife rest 3, be provided with cutter 31.
Described cutter 31 is symmetrical in the axis of scroll chuck 6 with described roller 51 and is arranged at the both sides of described axis, and described A gear 21 is all consistent with described second tooth bar 41 specifications parameters.
Described base plate 1 can slide by the described axis direction along described scroll chuck 6 on lathe.
Arrange like this, this device is placed on lathe and uses, and is used for processing the slender axles 7 of all size.In tool rest bracket 2, be provided with motor, and motor is connected with A gear 21.Like this, motor can drive A gear 21 to rotate, and after A gear 21 rotates, this device just can have been worked.Arrange like this, the cutter 31 of this device just can processing slim axle 7, cylindrical that can either car slender axles 7, end face that also can car slender axles 7.
Arrange like this, on scroll chuck 6, step up the axle of required processing.When needs cutter 31 turning axle, need knife rest 3 to do feed motion to axle, this time, A gear 21 will active rotation, due to A gear 21 and the 11 engagement fit motions of first tooth bar, and first tooth bar 11 is fixed on base plate 1, described when A gear 21 rotates, tool rest bracket 2 will slide on base plate 1.Like this, as long as control the rotation direction of A gear 21, just can control the direct of travel of cutter 31.
In the time of processing slim axle 7, need to be by cutter 31 near slender axles 7.So just need motor to drive A gear 21 to clockwise rotate.After A gear 21 clockwise rotates, tool rest bracket 2 is just close to slender axles 7.A gear 21 and the 22 engagement fit transmissions of second gear, second gear 22 and the 41 engagement fit transmissions of second tooth bar, and second tooth bar 41 is fixedly connected on described support portion base 4, like this, after A gear 21 clockwise rotates, support portion base 4 will be close to slender axles 7, and support portion base 4 is consistent with the speed of tool rest bracket 2.Again because cutter 31 is symmetrical in the axis of scroll chuck 6 with roller 51 and the both sides with axis are set, like this, cutter 31 and roller 51 are consistent to the distance of slender axles 7.When cutter 31 just contacts preparation processing with slender axles 7 when, roller 51 has also contacted with slender axles 7, and corresponding support force is provided.Like this, cutter 31 is in processing slim axle 7, and slender axles 7 just can not occur bending and deformation.So just can indirectly solve the problem of slender axles 7 poor rigidity in process.Arrange like this, when using this device processing slim axle 7 on lathe, just can not re-use toply, saved procedure of processing, increase work efficiency.
In order to make this device there is better technique effect, be also provided with spring portion 42 and spring 53.Like this, this device was long service time originally, when having produced error, can adjust by spring 53, when cutter 31 is contacted with slender axles 7 with roller 51, can continue to keep corresponding dynamic balance.Like this, just can make roller 51 can, in cutter 31 processing slim axles 7, provide corresponding support force all the time.Arrange like this, use this device just can process the slender axles 7 of random length and diameter, and the slender axles 7 that process are met the requirements, can not produce flexural deformation.
The utility model has solved the problem of slender axles poor rigidity in process, the higher defect of percent defective of processing slim axle in prior art in solution prior art, realize the percent defective that reduces processing slim axle, there is high accuracy, high efficiency advantage, also there is the function to the positioning and clamping of the slender axles of various diameters, increased the versatility of equipment.
