detailed description

As shown in Figures 1 to 7, the present invention includes a motor A1, a chuck A2, a tailstock, a knife rest 3 and a frame 4, and the motor A1 is fixed on the frame 4 through a motor bracket A5; the tailstock includes a tailstock bracket 6 And the tailstock base plate 7, the tailstock bracket 6 is installed on the machine base 4 through the tailstock base plate 7; the tailstock bracket 6 is equipped with a rotary top 8, and the rotary top 8 is concentric with the chuck A2; the upper end surface of the machine base 4 is provided with There are a plurality of grooves A41 parallel to the axial direction of the chuck A2, and the tailstock bottom plate 7 is fixed in the grooves A41 in the center of the machine base 4 through locking screws 9 .

There are two ways to connect the motor and chuck of the present invention:

In the first way, the motor shaft of the motor A1 is connected to the main shaft A11 through the main shaft bearing A10, and the collet A2 is installed on the main shaft A11. In this way, most of the force can be offset by the spindle bearing A when turning, which is beneficial to protect the motor and improve the rigidity of the power part.

In the second method, the motor shaft of the motor A1 is directly connected to the chuck A2 through a Morse taper. Compared with the first method, the main shaft A and the main shaft bearing A are omitted in this method, and the structure is simpler and the cost is saved.

There are also two ways to connect the rotary top 8 and the tailstock support of the present invention:

In the first way, a top bearing 12 is arranged in the opening of the tailstock bracket 6 , and the revolving top 8 is connected to the tailstock bracket 6 through the top bearing 12 .

In the second way, the opening of the tailstock bracket 6 is provided with a moving screw 13, and one end of the moving screw 13 close to the chuck A2 is equipped with a rotary top 8 through a screw bearing sleeve 14, and the other end is a screw nut 15.

Compared with the two, the first structure is relatively simple and cost-saving, but compared with the second structure, it is more troublesome to adjust the rotary center 8, and it must be adjusted by moving the bottom plate 7 of the tailstock and the base 4. The relative position is used to adjust the relative position of the rotary top 8 and the chuck A2 (the tailstock bottom plate 7 can be moved to the relative position along the groove 41 and then fixed by the locking bolt 9 to realize the function of tightening the wood to be processed). In the second method, on the basis of this, it is only necessary to turn the moving screw 13 to realize the telescopic movement of the rotary center 8, adjust the distance between the rotary center 8 and the chuck A, and then tighten the workpiece. Refer to Figure 1 and Figure 2, The moving screw rod 13 can be locked and loosened by the locking screw.

In addition, both the center bearing 12 and the screw bearing sleeve 14 of the present invention are provided with two bearings, and the rotary center 8 is fixed on the inner bearing. This design is to prevent left and right shaking during processing, make the connection more stable, and improve processing accuracy.

When the present invention is in use, the chuck A and the rotary top 8 fix the processed wood (pre-processed part), the motor A1 drives the chuck A to rotate, and then the turning tool can be held by hand to cut on the rotating wood. Wherein, the tool rest 13 is placed in order to facilitate the turning tool. The tool rest 13 of the present invention is specifically designed to be L-shaped (conveniently assembled on the support 4), installed on the top of the support 4, and the horizontal plane of the tool rest 3 is passed through the locking screw. 9 is fixed in the groove A41 on the side of the base 4; the height of the vertical surface of the tool holder 3 is at the same height as the axis centerline of the rotary center 8 and the collet A2. This processing method is more flexible. In addition to processing round shapes, it can also process other objects of different shapes. Because one motor can only provide power in one direction, that is to say, the above method only provides the function of a manual lathe, and can be used in conjunction with a traditional bench drill. In addition, the present invention also provides an auxiliary lathe 20 to replace the processing method of a hand-held turning tool, and the combined use of the two is more effective (see the description of the auxiliary lathe later for details).

In order to further improve the versatility of the present invention, a puncher is also installed on the tailstock base plate 7, so that the present invention has a punching function concurrently; the puncher includes a positioning bracket 16 and a positioning sleeve, and the positioning sleeve is arranged on the positioning bracket 16. In the opening, the end close to the screw nut 15 is inwardly concave, and the positioning sleeve is concentric with the moving screw 13 . In addition, in conjunction with this, the outer end surface of the screw nut 15 is inwardly concave arc-shaped, or the outer end surface of the screw nut 15 is equipped with a plastic protective cover, and the outer end surface of the plastic protective cover is inwardly concave arc-shaped. This can coincide with the spherical surface of the beads, ensuring that beads of different sizes can automatically find the center when they are clamped. And the side of the screw nut 15 that contacts the beads is inwardly recessed in an arc shape or a protective cover is set, further reducing the damage to the beads.

The present invention rotates the tailstock base plate 7 by 180 degrees when punching holes, so that the positioning bracket 16 is opposite to the chuck A2. The twist drill is installed on the chuck A2, and the beads are clamped between the positioning bracket 16 and the screw nut 15, and then the tailstock base plate 7 is pushed to move closer to or away from the chuck A2 to realize the punching function.

Another punching method does not need to rotate the tailstock bottom plate 7, but only needs to install the puncher between the tailstock bracket 6 and the chuck A. When in use, remove the rotary top 8 and fix the beads Hold between the positioning bracket 16 and the screw bearing sleeve 14, and then push the tailstock bottom plate 7 to move closer to or away from the chuck A2 to realize the punching function. The principle that two kinds of punching are realized is the same, and the first one carries out arc-shaped design on the screw nut 15, which is more conducive to protecting the clamped Buddha beads. The operation is also very convenient.

The present invention can realize that the central position of the puncher is consistent with the chuck A through the following two methods, that is, track type and baffle type. Orbital type: the base of the hole puncher is provided with a slider that fits with the groove A (or track) of the machine base 4 to ensure that the hole puncher advances in a straight line along the groove A of the machine base 4 when punching. Realize that the central position of the punching device remains unchanged and maintains concentricity with the chuck A. Baffle type: Fix a baffle next to the lathe track as a backing, let the puncher advance along the baffle and groove A to ensure a straight forward direction, the center position of the punching device remains unchanged, and is concentric with the chuck A The left and right center positions of the holes are consistent.
