Abstract

The utility model discloses a bench woodworking drilling machine which is a special machine for the use of drilling and riveting of a woodworker. The utility model can also be used as the matching devices of a comprehensive multifunctional woodworking machine tool, drilling and riveting. The utility model is characterized in that a spline shaft as a rotating shaft transmits the power through a belt pulley arranged on a splined sleeve in a bearing hole positioned on the upper part of a sleeve cylinder, and namely, the main body of a bench drill; therefore, the rotating shaft obtains the rotary movement; a gear is rotated with a handle, causing a rack extending out of the sleeve cylinder to move up and down; the rotating shaft is driven to slide up and down in the splined sleeve; the rotating shaft moves downwards, the drilling hole is fed inwards, and the rotating shaft moves upwards to cause a drill bit to lift a retracting cutter; the balanced component of the vertical motion force of the rack is a roll type spring. The utility model has the advantages of perfect and reliable performance, simple and portable structure and low cost.

Description

Bench Woodworking drilling machine

The utility model belongs to woodworking machinery.

Woodworking machinery is along with the high-speed development and modernization of China's economy and people's lives, field development such as, building trade all at family expenses carpenter device, Wooden Pattern Making are very fast,, the carpenter still lacks with boring, Mortise machine tool, heavy and the very high Metal Cutting Machine Tool of cost are all used in carpenter's boring, this is very unfavorable, and it is also very backward that existing carpenter beats fourth of the twelve Earthly Branches mode.

The purpose of this utility model is to design a kind of perfect performance, uses reliably, and simply light, cheap bench wood lathe, it can be used as single wood boring machine, also can be used as the comprehensive multifunctional wood craft machines, holes, beats the corollary apparatus at the fourth of the twelve Earthly Branches.

The utility model mainly by rotating shaft, spline housing, sleeve (bench drill body), rolling bearing, shaft seating, tooth bar, gear, bearing pin, rolling spring, handgrip, belt pulley, drill point is first-class forms.

The design's technical conceive, be to be provided with a shaft seating, it utilizes the rolling bearing inner ring that is pressed in the endoporus to connect with rotating shaft, accepted the rotation of rotating shaft, fixed tooth bar on the outer garden face of shaft seating, tooth bar stretches out in the sleeve outside by the bar hole on sleeve right side, bearing and tooth bar are subjected to placing restrictions on of bar hole together, can not rotate, tooth bar in bar hole up and down reciprocatingly straight line move, drive rotating shaft and in spline housing, slide up and down.Rotation and straight line that said mechanism and technical measures have constituted rotating shaft move, and rotatablely moving and holing downwards of rotating shaft just sent to and upwards two kinds of motions of withdrawing lifting.

In the back of gear shaft, the rolling spring is installed, dynamic balance element when it is the quiet state of gear one tooth bar.

Following with reference to comprehensive explanation structure of the present utility model of accompanying drawing and action principle:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a left view.

Fig. 3 is a vertical view.

Fig. 4 is a vertical view cutaway drawing.

Fig. 5 is a rolling spring assembly schematic diagram.

With reference to accompanying

drawing

1,2,3,4, two ends are housed by rolling bearing (5), (6) respectively up and down at sleeve (4), pressing spline housing (2), (3) in its inner ring separately, rotating shaft (1) is a splined shaft, be applied in up and down in two spline housings, upper spline cover (2) connects with key (14), and belt pulley (13) is installed.

Rotating shaft (1) middle part device has rolling bearing (16), its outer ring is pressed in the endoporus of shaft seating (7), the outer garden face of bearing (7) is being fixed tooth bar (8), and its bar hole (20) by sleeve (4) right side stretches out the outside in sleeve (4).

Two ears (21) on sleeve (4) right side, bottom are equipped with bearing pin (10), gear (9) is housed on it, see Fig. 4, the bearing pin front end is installed handgrip (12), rolling spring (11) is installed in the rear end, referring to Fig. 5, wind spring (11) the inner is clipped in the narrow groove at bearing pin (10) rear portion and uses screw pinning, outer end to be screwed on sleeve (4) ear (21) upper left side.

Power makes rotating shaft (1) obtain rotation fortune fortune by belt pulley (13) through spline housing (2).With the left-handed handgrip of hand (12), constantly shredding of wind spring (11), gear (9) driving rack (8) drives bearing (7) and the downward straight line of rotating shaft (1) moves, realize holing and sending to, make handgrip (12) dextrorotation after boring finishes, oppositely resilience of wind spring (11), screen resilience makes gear (9) counter-rotating through bearing pin (10), driving rack (8) drives rotating shaft (1) the lifting withdrawing that moves up through bearing (7), so comes and goes, and realizes carpenter's boring, beats the fourth of the twelve Earthly Branches and process.

After the completion of processing, slowly decontrol handgrip (12), spring force makes rotating shaft (1) get back to the peak resting position.

Fig. 2 has reflected the utility model, hole, beat an example of the corollary apparatus at the fourth of the twelve Earthly Branches as multi-functional carpenter's planer, it is installed in the appropriate location of multi-functional carpenter's planner body (25), power is by the belt pulley on the thicknessing and planning machine (26), through two directive wheels (17), (18) on the utility model, make belt (19) do vertical transmission, process belt pulley (13) will move and transmission of power arrives rotating shaft of the present utility model (1)) on.

Claims

1, a kind of novel bench wood lathe, by rotating shaft (1), on, following spline housing (2), (3), sleeve (4), rolling bearing (5), (6), bearing (7), tooth bar (8), gear (9), bearing pin (10), rolling spring (11), handgrip (12), belt pulley (13), key (14) and drill chuck compositions such as (15), it is characterized in that: rotating shaft (1) transmits power by the belt pulley (13) that is connected in key (14) on the upper spline cover (2), acquisition rotatablely moves, tooth bar (8) is connected on the bearing (7), move up and down with handgrip (12) swing pinion (9) driving rack (8), make rotating shaft (1) boring downwards send and upwards promote withdrawing to, gear (9) and bearing pin (10) rear end are equipped with rolling spring (11), its elastic force makes rotating shaft (1) upwards promote and be still in the extreme higher position, rotating shaft (1) lower end cone is installed drill chuck (15), and its claw clamps drill bit.
