The content of the invention
It is an object of the invention to overcome deficiency of the prior art, there is provided a kind of boring auxiliary mould, can not break It is set to possess bore hole function on the basis of bad existing lathe agent structure.
To solve prior art problem, the technical solution adopted by the present invention：A kind of boring auxiliary mould, including boring component And transmission component；
Boring component includes boring head, ram and boring cutter；Ram is slidably mounted on a side surface of boring head, boring cutter peace Mounted in the center of ram；
Transmission component includes handle, the first power transmission shaft, second driving shaft, connecting shaft and fixing axle；Handle is arranged on first One end of power transmission shaft, the first power transmission shaft are connected by gear pair with second driving shaft, and second driving shaft passes through the first worm and wormwheel Pair is connected with connecting shaft, and connecting shaft passes through the second worm-gears and fixed axis connection；Pass through worm rack between fixing axle and ram Pair connection；Second driving shaft is coaxially disposed with boring head, and fixing axle is arranged on boring head；First worm-gears and the second snail The helical angle of worm screw in worm-gears is 0 °；Rotational handle can drive ram to slide.
Preferably, balancing weight is additionally provided with boring head.
Preferably, in addition to the first power transmission shaft the dial being coaxially disposed, dial are used for the displacement for adjusting ram.
Preferably, the gearratio of transmission component is 5~10:1.
Preferably, the secondary group number of worm rack is two groups, and is symmetrical arranged, the rotation of the worm screw in two groups of worm rack pairs To identical.
Preferably, gear pair is the combination of spur gear pair, bevel gear pair or both.
The device have the advantages that：
1. needing to carry out existing lathe simple dismounting it can be made to possess bore hole function, meet significantly middle-size and small-size The production requirement of processing factory, improve its working ability so as to improve the level of profitability.
2. transformation process is simple to operation, without the agent structure for destroying lathe, so as to increase while ensure that precision Additional functionality is added.
3. being realized by the kinematic pair of big speed ratio to regulation of the boring cutter compared with thin tail sheep, machining accuracy is further improved.
4. the tool structure is simple, construction is reliable, and cost is cheap, is particularly suitable for the processing needs of middle-size and small-size processing factorie.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention Technical scheme, and can not be limited the scope of the invention with this.
As illustrated in fig. 1 and 2, a kind of boring auxiliary mould, including boring component and transmission component.
Boring component includes boring head 16, ram 17 and boring cutter 18.Ram 17 is slidably mounted on the side table of boring head 16 On face, boring cutter 18 is arranged on the center of ram 17.
Transmission component includes the first power transmission shaft 3, second driving shaft 6, connecting shaft 9 and fixing axle 14.The front end of first power transmission shaft 3 Handle 1 is installed, the first drive bevel gear 4 is installed in its rear end.The front end installation driven wheel of differential 5 of second driving shaft 6, its rear end First spur gear 8 is installed.The first worm screw 7 is installed in the front end of connecting shaft 9, and the second worm screw 10 is installed in its rear end.The center of fixing axle 14 Second spur gear 11 is installed, each one the 3rd worm screw 12 of installation in its both ends, the rotation direction of two the 3rd worm screws is identical, the 3rd worm screw with Axle sleeve 15 is also equipped with fixing axle between second spur gear.Fixing axle 14 is arranged on inside boring head 16, in ram 17 A pair of spur racks 13 are installed on trailing flank.Drive bevel gear 4 engages with driven wheel of differential 5, the first spur gear 8 and the first worm screw 7 Engagement, the second spur gear 11 engage with the second worm screw 10, and the 3rd worm screw 12 and spur rack 13 engage.First worm screw 7 and the second snail The helical angle of bar 10 is 0 °, and the first power transmission shaft 3 and second driving shaft 6 are also fixed in a fixed plate by bearing block, with It is easy to uniformly install.
Due to being mounted with other components on boring head 16, therefore it result in barycenter and shift.In order to solve the problem, One balancing weight is installed on boring head 16 so that the barycenter of whole boring head 16 overlaps with its center of rotation.
In order to improve feed accuracy, therefore by the gearratio design of transmission in the larger context, such as 5~10:1, by This causes handle 1 to rotate larger angle, and small change only occurs for the displacement of boring cutter 18.
The operation principle and process of the present invention
First the chuck of lathe is removed, then boring head 16 is arranged on lathe spindle.Other components are in turn mounted to On the correct position of lathe and ensure that transmission tightly engages.Then after workpiece is fixed, rotational handle 1 simultaneously observes scale Disk 2 is to determine the amount of feeding.Finally start lathe and complete bore hole.Because the helical angle of the first worm screw 7 and the second worm screw 10 is 0 °, Therefore the rotation of handle 1 can't be caused during main axis.3rd worm screw 12 is engaged with self-locking performance with spur rack 13, without Other locking devices are set on ram 17.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation Also it should be regarded as protection scope of the present invention.
