Abstract
The utility model relates to motor-drivenly on a kind of boring machine attacks casing inner thread device, comprise body (6) and the transmission device (11) with body (6) thread connection, it is characterized in that: described body (6) is provided with the first cavity (9) and the second cavity (10), taper shank (8) is fixed in the first cavity (9) by screw (7), friction lever (2) is embedded in the second cavity (10), and screw tap (1) is fixedly connected in the end of friction lever (2).After adopting technique scheme, the utility model effectively can realize the internal thread of machining box on horizontal boring machine.
Description
Technical field
The utility model relates to a kind of chasing bar, especially relates to motor-drivenly on a kind of boring machine attacking casing inner thread device.
Background technology
Casing has more inner bolt hole usually, often adopts hand tapping in factory, efficiency is low, and labour intensity is large, is not easy the precision ensureing screw.Chinese patent literature (CN104057161A) discloses a kind of internal thread tapping machine and tapping method thereof, comprises upright drill, scroll chuck, guiding catch bar, screw tap toggle and screw tap.Its main points are: guiding catch bar centre is provided with Morse's cone pin, two ends are provided with cylinder backing pin, and the lower end of Morse's cone pin is provided with cylinder taper pin, and Morse's cone pin and cylinder backing pin are solidly connected with guiding catch bar; Part is arranged on scroll chuck, and the main shaft of upright drill drives successively and guides catch bar, screw tap to rotate part tapping.This chasing bar structure is simple, easy to manufacture, expense is low; Adopt and guide catch bar to guide screw tap part to be carried out to the tapping of internal thread on upright drill, part is easy to loading and unloading, technique is simple, processing ease, positioning precision are high, shorten the lay day of part, reduce the labour intensity of workman and the loss of cutter, improve production efficiency, reduce production cost, the part quality of processing be stable, good reliability.But such scheme does not utilize horizontal boring machine and does not possess self-protection function.
Summary of the invention
The purpose of this utility model is to provide the inner thread device of machining box on a kind of horizontal boring machine with defencive function.
The technical scheme realizing above-mentioned purpose is: motor-drivenly on a kind of boring machine attack casing inner thread device, comprise body and the transmission device with body thread connection, be fixed in the first cavity, friction lever is embedded in the second cavity, and screw tap is fixedly connected in the end of friction lever.
Described transmission device comprises and the adjustment block of body thread connection and the pin mother with adjustment block thread connection, is provided with the spring connecting body and friction lever in described second cavity.
After adopting technique scheme, there is following beneficial effect:
(1) can on horizontal boring machine the internal thread of machining box;
(2) reduce artificial labour intensity, improve production efficiency;
(3) the utility model is easy and simple to handle, and cost is low, wide market.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1. screw tap; 2. friction lever; 3. pin is female; 4. adjustment block; 5. spring; 6. body; 7. screw; 8. taper shank; 9. the first cavity; 10. the second cavity; 11. transmission devices.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: motor-drivenly on a kind of boring machine attack casing inner thread device, comprise body 6 and the transmission device 11 with body 6 thread connection, be fixed in the first cavity 9, friction lever 2 is embedded in the second cavity 10, and screw tap 1 is fixedly connected in the end of friction lever 2.
For protection chasing bar and the work-piece tapping adapting to unlike material, described transmission device 11 comprises and the adjustment block 4 of body 6 thread connection and the pin mother 3 with adjustment block 4 thread connection, is provided with the spring 5 connecting body 6 and friction lever 2 in described second cavity 10.
Operation principle of the present utility model is as follows: during tapping, makes screw tap 1 enter screw, and its body 6 advances along taper shank 8, is controlled the relative rotation of body 6 and taper shank 8 by screw 7.During use, the spring 5 in body 6 heads on the taper-face contact of friction lever 2 and regulating block 4, and produces the cutting of frictional force drive screw tap, and when bottom attacked by screw tap or cutting force is excessive, friction lever 2 skids in regulating block, at this moment screw tap 1 can be exited.The pressure of spring 5, can be regulated by pin mother 3.
Claims (2)
