Abstract
The invention discloses a power head. The power head comprises an engine body, the front end portion of the engine body is provided with an assembly head matched with a drill, an air cylinder driving the assembly head to rotate along with a fixed axle is arranged in the middle of the engine body, the moving direction of the air cylinder is parallel to the axis of the engine body, and a pneumatic motor is connected between the air cylinder and the assembly head. In a working process, a driving structure composed of the air cylinder and the pneumatic motor is relatively light in self-weight, and therefore a whole structure of the power head is lighter and more convenient to use.
Description
Technical field
The present invention relates to rig necessary accessories technical field, particularly a kind of unit head.
Background technology
In the general rig course of work, usually need to adopt unit head provide power for drill bit, and, along with the improving constantly of working strength, people also have higher requirement to the performance of unit head.
In the current existing unit head course of work, normally adopt hydraulic cylinder or motor as power source.Yet, although above-mentioned two kinds of motive power outputting apparatus can meet basic need of work, because its equipment self-weight is larger, cause the overall structure of unit head comparatively heavy, the process operations difficulty such as movement are large, cause inconvenience to relevant production work.
Therefore, the important technological problems that how to make lighter those skilled in the art of being of structure of unit head need to solve at present.
Summary of the invention
The purpose of this invention is to provide a kind of unit head, the structure of this unit head is comparatively light.
For solving the problems of the technologies described above, the invention provides a kind of unit head, comprise body, the leading section of described body is provided with the assembly head suitable with drill bit, the middle part of described body is provided with the cylinder that drives described assembly head System of Rotating about Fixed Axis, the direction of motion of described cylinder parallels with the axis of described body, and is connected with air motor between described cylinder and described assembly head.
Preferably, the sidepiece of described body is provided with damper.
Relative above-mentioned background technology, unit head provided by the present invention, comprise body, the leading section of described body is provided with the assembly head suitable with drill bit, the middle part of described body is provided with the cylinder that drives described assembly head System of Rotating about Fixed Axis, the direction of motion of described cylinder parallels with the axis of described body, and is connected with air motor between described cylinder and described assembly head.In the course of work, the deadweight of the drives structure that this kind of cylinder and air motor form is less, thereby makes the overall structure of described unit head lighter.
In another preferred version of the present invention, the sidepiece of described body is provided with damper.In the course of work, after anterior drill bit arrives the depth capacity of specifying boring, outside the hole of the front end of described damper and corresponding boring, the scope of operation offsets, to stop described unit head and drill bit to continue deeply, thereby effectively guaranteed the operating accuracy of drill bit and described unit head, and made its course of work more reliable and more stable.
The accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The assembly structure schematic diagram of the unit head that Fig. 1 provides for a kind of specific embodiment of the present invention.
The specific embodiment
Core of the present invention is to provide a kind of unit head, and the structure of this unit head is comparatively light.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, the assembly structure schematic diagram of the unit head that Fig. 1 provides for a kind of specific embodiment of the present invention.
In the specific embodiment, unit head provided by the present invention, comprise body 11, the leading section of body 11 is provided with the assembly head suitable with drill bit 12, the middle part of body 11 is provided with the cylinder 13 that drives assembly head 12 System of Rotating about Fixed Axis, the direction of motion of cylinder 13 parallels with the axis of body 11, and is connected with air motor 14 between cylinder 13 and assembly head 12.In the course of work, this kind of cylinder 13 is less with the deadweight of the drives structure of air motor 14 compositions, thereby makes the overall structure of described unit head lighter.
Further, the sidepiece of body 11 is provided with damper 15.In the course of work, after anterior drill bit arrives the depth capacity of specifying boring, outside the hole of the front end of damper 15 and corresponding boring, the scope of operation offsets, to stop described unit head and drill bit to continue deeply, thereby effectively guaranteed the operating accuracy of drill bit and described unit head, and made its course of work more reliable and more stable.
In summary, the unit head provided in the present invention, comprise body, the leading section of described body is provided with the assembly head suitable with drill bit, the middle part of described body is provided with the cylinder that drives described assembly head System of Rotating about Fixed Axis, the direction of motion of described cylinder parallels with the axis of described body, and is connected with air motor between described cylinder and described assembly head.In the course of work, the deadweight of the drives structure that this kind of cylinder and air motor form is less, thereby makes the overall structure of described unit head lighter.
Above unit head provided by the present invention is described in detail.Applied specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
Claims (2)
1. a unit head, it is characterized in that: comprise body, the leading section of described body is provided with the assembly head suitable with drill bit, the middle part of described body is provided with the cylinder that drives described assembly head System of Rotating about Fixed Axis, the direction of motion of described cylinder parallels with the axis of described body, and is connected with air motor between described cylinder and described assembly head.
