Description
[technical field]
The utility model designs machinery field, and in particular to it is a kind of can automatic withdrawal tapping machine.
[background technique]
Existing bench tapping machine small lot processing in using extensively, be in tapping, operate rotational handle, make main shaft to
Lower slider, while main shaft rotates and screw tap mounted thereto is driven to rotate, and completes the tapping to workpiece, and after completing tapping,
Since main shaft drives screw tap rotation decline to be linked together with workpiece, so to operate tapping machine, invert main shaft and reversed
Rotational handle could withdraw screw tap from workpiece, and operating procedure is more in the process, and is easy that screw tap is made to fracture in workpiece,
And tapping depth very important person is control, inaccurately.
Authorization Notice No. is the Chinese utility model patent of CN20673229U, discloses a kind of foot-operated tapping machine, passes through
Lifting motor is installed to main shaft, and connects induction type floor push sensor, by turn of the activity control main shaft of operator's foot
It is gone up and down to machine.This mode system complex, cost requirement is high, is unfavorable for small-sized workshop and uses, and to the activity of operator foot
It is required that it is high, it is easy to operate by mistake.
[utility model content]
The purpose of this utility model is that in view of the deficiencies of the prior art, provide it is a kind of can automatic withdrawal tapping machine, solution
Certainly in the prior art withdrawing when cumbersome operation improve tapping precision while according to accurate control tapping height.
To achieve the above object, the technical solution of the utility model is:
It is a kind of can automatic withdrawal tapping machine, including handle 2, rack 3, main shaft 4, transmission case 5, workbench 6,7 and of pillar
Pedestal 8, handle 2 are mounted on the side of rack 3.It further include turning to switching device 1, the steering switching device includes adjusting bracket 1-
1, limit sensors 1-2 and screw 1-3.The adjusting bracket 1-1 is L shape, and the limit sensors 1-2 is arranged in adjusting bracket 1-
The inside of 1L shape bottom, the other side adjusting bracket 1-1 are provided with sliding groove 1-4；The screw 1-3 is mounted in sliding groove 1-4, will
Adjusting bracket 1-1 is fixed on the side that rack 3 installs handle 2, and the handle 2 rotates through operation and main shaft 4 is driven to move down, institute
Limit sensors 1-2 can be touched by stating after handle 2 turns an angle.
Further, the steering switching device 1 is connected with 3 rigid removable of rack.
The side for turning to switching device and being mounted on rack, the steering switching device and rack are rigidly removable by screw
Connection is unloaded, the position that screw is removable adjusting bracket is unclamped.
The handle touches limit sensors after turning an angle, just cannot rotate further along former direction, lead at this time
Axis and screw tap can rotate backward beginning withdrawing, and operator's opposite direction rotational handle can be realized withdrawing, not need in whole process
Operation bidirectional.
Compared with prior art, the utility model limits the rotation angle of handle, also using setting limit sensors
It is the distance for limiting screw tap and moving down, when handle triggers limit sensors, screwing operation has been completed, and main shaft inverts at this time
Screw tap is driven to start withdrawing, simple to operate, high-efficient, it is smaller that screw tap receives additional impact, improves life of tap.
Further, the installation site for turning to switching device is adjustable, and switching dress can be turned to according to tapping length adjustment
The installation site set realizes the hole processing of different length, can guarantee and completes tapping precision.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the utility model embodiment 1.
Fig. 2 is the detailed figure for turning to switching device.
It is as follows that corresponding structure is numbered in figure:
1, switching device 2, handle 3, rack 4, main shaft 5, transmission case 6, workbench 7, pillar 8, pedestal are turned to
1-1, adjusting bracket 1-2, limit sensors 1-3, screw 1-4, sliding groove.
[specific embodiment]
Clear and complete description is carried out to the technical solution of the utility model below in conjunction with attached drawing.Obviously, described
Embodiment is a part of the embodiment of the utility model, instead of all the embodiments.Based on the embodiments of the present invention, originally
The those of ordinary skill in field other embodiments obtained under the premise of not making creative labor, belong to this reality
With novel protection scope.
Embodiment 1: referring to Fig.1:
It is a kind of can automatic withdrawal tapping machine, including handle 2, rack 3, main shaft 4, transmission case 5, workbench 6,7 and of pillar
Pedestal 8.The bottom end of pillar 7 is fixedly mounted on pedestal 8, the upper end installation frame 3 of pillar 7, and handle 2 is installed in the side of rack 3,
Handle 2 rotates the lifting of adjustable main shaft 4.Transmission case 5 is installed at the top of rack 3, and transmission case 5 drives main shaft 4 to rotate.Workbench
6 are arranged between rack 3 and pedestal 8, and the side of workbench 6 and main shaft 4 are slidably connected, and workbench 6 can glide on main shaft 4
It is dynamic, to adjust the height of workbench 6.
Handle 2 is mounted on the side of rack 3, and handle 2 adjusts the lifting of main shaft 4 by transmission mechanism.
It further include turning to switching device 1, turning to switching device includes adjusting bracket 1-1, limit sensors 1-2 and screw 1-3.
Adjusting bracket 1-1 is L shape, and the L shape bottom inside of adjusting bracket 1-1, the other side of adjusting bracket 1-1 is arranged in limit sensors 1-2
It is provided with sliding groove 1-4, the screw 1-3 is mounted in sliding groove 1-4, and adjusting bracket 1-1 is fixed on rack 3 and installs handle 2
Side, the handle 2 through operation rotate and drive main shaft 4 to move down, the handle 2 can touch after turning an angle
