Problems solved by technology
[0002] In the existing design, the positioning of the drilling depth of the drilling machine is mostly realized by the adjustment of the sleeve positioning rod. During the long-term use, the racks, sleeves, bearings and other components of the drill rod will be worn to a certain extent. Therefore, For some processing workpieces with high requirements for drilling and reaming depth, the positioning accuracy cannot meet the requirements

Embodiment Construction
[0014] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0015] A positionable drill press drilling device such as figure 1 As shown, the sleeve 1 and the spindle drill rod 8 arranged on the sleeve 1 are included, and the tail of the spindle drill rod 8 ( figure 1 The right side of the middle) is provided with a threaded 9 bottom hole, a pulley 2 is fixed on the outside of the sleeve 1 through a washer 3, and an adjustable threaded rod 7 is arranged at the tail of the main shaft drill rod 8 through a spline shaft 4. The adjustable thread The rod 7 is connected to the spline shaft 4 through the lock nut 6, so that the threaded rod 7 can be adjusted to be locked on the spline shaft 4.

The invention discloses a drilling machine drilling device capable of positioning. The drilling machine drilling device comprises a sleeve, and a main shaft drilling rod arranged on the sleeve, and is characterized in that a threaded bottom hole is formed in the tail part of the main shaft drilling rod; a belt pulley is fixed on the outer surface of the sleeve through a washer; an adjustable threaded rod is arranged at the tail of the main shaft drilling rod through a spline shaft; the adjustable threaded rod is connected with the spline shaft through a locking nut; an annular containing cavity is formed inward in the tail of the sleeve; a spring is fixedly arranged in the annular containing cavity; the spring is connected with an annular measuring scale; the annular measuring scale can move along the annular containing cavity; the other end of the annular measuring scale is propped against the end surface of a nut close to the locking nut; a plurality of annular scale lines are arranged on the annular measuring scale from the end part to the spring side. A measuring device is added to provide convenience for positioning the drilling depth, and the measuring device has low probability of deforming or bending, so that the positioning accuracy is improved, and further the positioning depth is prevented from big error in the circumferential direction.
Description
technical field [0001] The invention relates to a positionable drilling machine drilling device. Background technique [0002] In the existing design, the positioning of the drilling depth of the drilling machine is mostly realized by the adjustment of the sleeve positioning rod. During the long-term use, the racks, sleeves, bearings and other components of the drill rod will be worn to a certain extent. Therefore, For some processing workpieces with high requirements for drilling and reaming depth, the positioning accuracy cannot meet the requirements. Contents of the invention [0003] In view of the above problems, the present invention provides a positionable drill press drilling device, adding a measuring device to facilitate the positioning of the drilling depth, and the measuring device is not prone to deformation or bending, which improves the positioning accuracy, and further prevents the positioning depth from moving along the A large error occurs in the circumf...
