Referring to fig. 1 and 2, a fixture for a dual-purpose tapping and drilling machine includes a placement table 1, a mounting seat 2, an adapter 3, a fastener 4, a movable clamping portion 5 and a threaded rod 6.

The top surface of the placement table 1 has a convex groove 1a. The narrower portion of the convex groove 1a is up and out of the top surface of the placement table 1, and the wider portion is down. The convex groove 1a is oriented in a first horizontal direction.

The mounting seat 2 is placed on the placing table 1, the top surface is provided with two bulges, one bulge is used as a fixed clamping part 2a, the other bulge is used for connecting a subsequent threaded rod 6, and the bottom surface is provided with a T-shaped groove 2b. The narrower portion of the male slot 1a is down and out of the bottom surface of the mount 2 and the wider portion is up. The T-shaped groove 2b is oriented in a second horizontal direction perpendicular to the first horizontal direction, which correspond to the X-axis and the Y-axis, respectively.

Referring to fig. 2 and 3, the adapter block 3 includes a lower block 3b and an upper block 3a. The lower block 3b remains in the narrower portion of the tongue 1 a. The lower block 3b and the narrower portion are of equal width, enabling the mounting base 2, the adapter 3 to be moved together in a first horizontal direction relative to the placement table 1. The upper block 3a remains in the narrower portion of the T-shaped slot 2 b. That is, the upper block 3a and the lower block 3b cross each other in a cross shape, and the portion of the upper block 3a beyond the lower block 3b is fitted to the top surface of the placement table 1. The upper block 3a and the narrower portion are also equally wide, enabling the mount 2 to move in a second horizontal direction relative to the adapter block 3. In summary, the mount 2 is movable in the first horizontal direction and in the second horizontal direction with respect to the placement table 1.

The fastener 4 is composed of a bolt 4a and a nut 4 b.

Referring to fig. 2 and 5, for the bolt 4a, the screw is inserted through the adapter block 3, and the nut is located at the wider portion of the T-shaped groove 2b, and is attached to two first connection surfaces 2b1 of the T-shaped groove 2 b. That is, the height of the upper block 3a is slightly smaller than the height of the narrower portion of the T-shaped groove 2b, and the nut is fitted to the two first connecting surfaces 2b1 by the gravity of the bolt 4a itself.

Referring to fig. 2, the nut 4b is located at a wider portion of the male groove 1a and is restrained from rotating. More specifically, the nut 4b may use a square nut 4b, the width of the square nut 4b being the same as the width of the wider portion. The nut 4b can be attached to the two second connection surfaces 1a1 of the male groove 1 a. That is, the height of the lower block 3b is slightly smaller than the height of the narrower portion of the convex groove 1a, and the bolt 4a and the nut 4b are rotated, so that only up and down movement is possible, and the upward movement can be applied to the two second connection surfaces 1a1. By moving the nut 4b upward, the bolt 4a and the nut 4b press the first connection surface 2b1 and the second connection surface 1a1, respectively, so that the mounting base 2 can be relatively fixed to the placement table 1. Conversely, by the downward movement of the nut 4b, the fastener 4 is loosened, and the mount 2 can be moved in the first horizontal direction and in the second horizontal direction with respect to the placement table 1, thereby adjusting the position.

Obviously, an operation capable of rotating the bolt 4a is also required.

Referring to fig. 2 and 4, in some embodiments, the nut of the bolt 4a may be hexagonal, and the top surface of the mounting seat 2 has a bar-shaped groove 2c, and the bar-shaped groove 2c communicates with a wider portion of the T-shaped groove 2 b.

Referring to fig. 2, the movable clamping portion 5 is slidably connected to the top surface of the mounting base 2. More specifically, the top surface of the mounting seat 2 may have a groove 2d, a linear guide rail may be installed in the groove 2d, and the movable clamping portion 5 is installed on a mounting slider matched with the linear guide rail.

The workpiece is clamped through the movable clamping part 5 and the fixed clamping part 2a, correspondingly, the bottom surface of the movable clamping part 5 can be attached to the top surface of the mounting seat 2, the top surface of the movable clamping part 5 can be in the same plane with the top surface of the fixed clamping part 2a, the lengths of the movable clamping part 5 and the fixed clamping part 2a in the second horizontal direction are the same, the mounting position of the movable clamping part 5 on the mounting slide block is set, and the clamping surfaces of the movable clamping part 5 and the fixed clamping part 2a can be completely corresponding.

Referring to fig. 4 and 5, in some embodiments, the clamping surfaces of the movable clamping portion 5 and the fixed clamping portion 2a are provided with notches 5a, and the two notches 5a are aligned in the sliding direction of the movable clamping portion 5. More specifically, the notch 5a may be provided at an intermediate position of the holding surface.

When the workpiece is thin and narrow, the movable clamping portion 5 and the fixed clamping portion 2a interfere with the downward movement of the drill/tap after the workpiece is clamped by the movable clamping portion 5 and the fixed clamping portion 2 a. The notch 5a is designed, in which case the machining position of the workpiece can correspond to the notch 5a, interference being avoided by the notch 5 a.

Referring to fig. 1, a threaded rod 6 is threadedly coupled to the mounting. More specifically, the cylindrical nut 4b of the mating threaded rod 6 is mounted on the corresponding projection. The threaded rod 6 acts on the movable clamping part 5, so that the movable clamping part 5 and the fixed clamping part 2a can clamp a workpiece.

Referring to fig. 2, in some embodiments, the number of T-shaped grooves 2b is two. Correspondingly, there are two upper blocks 3a and two sets of fasteners 4. The sliding direction of the movable clamping part 5 is the second horizontal direction, and correspondingly, the threaded rod 6 and the linear guide rail can correspond to the position between the two T-shaped grooves 2b and are completely staggered with the two T-shaped grooves 2 b.

In some embodiments, the first way in which the threaded rod 6 enables the movable clamping portion 5 and the fixed clamping portion 2a to clamp a workpiece is by an end portion rotatably connected to the movable clamping portion 5. That is, the movable grip portion 5 is slid by rotation of the threaded rod 6. When the workpiece needs to be clamped, the threaded rod 6 is rotated until the movable clamping part 5 and the fixed clamping part 2a clamp the workpiece, so that the threaded rod 6 is difficult to rotate any further.

In some embodiments, the second way in which the threaded rod 6 enables the movable clamping portion 5 and the fixed clamping portion 2a to clamp a workpiece is by the end portion abutting against the movable clamping portion 5. That is, the movable clamp 5 is slid by hand. When the workpiece is required to be clamped, the movable clamping part 5 is manually slid until the movable clamping part 5 and the fixed clamping part 2a preliminarily clamp the workpiece, and the threaded rod 6 is rotated until the end part abuts against the movable clamping part 5, so that the threaded rod 6 is difficult to rotate further.

The application is used in the process of firstly placing a workpiece on the top surface of a placing seat between a movable clamping part 5 and a fixed clamping part 2a, then enabling the movable clamping part 5 and the fixed clamping part 2a to clamp the workpiece, then moving the mounting seat 2 relative to the placing table 1 along a first horizontal direction and a second horizontal direction, adjusting the position, and finally screwing a fastener 4 to relatively fix the mounting seat 2 on the placing table 1.

If the combination of the "screw cap of the bolt 4a may be of the hexagonal shape" and the "T-shaped groove 2b may be of the two" embodiment, it is obvious that the movable clamping portion 5 is possible to block the bolt 4a, thereby affecting the step of "tightening the fastener 4 and fixing the mounting base 2 to the placement table 1" relatively.

Referring to fig. 5, in some embodiments, based on the "two T-shaped grooves 2 b" embodiment, the nut of the bolt 4a may be an outer hexagon, and both vertical sides of the mounting seat 2 in the first horizontal direction have a bar-shaped groove 2c, and the bar-shaped groove 2c is connected to a wider portion of the T-shaped groove 2 b.

Compared with the embodiment of 'the nut of the bolt 4a can be a hexagon socket', a spanner can be used to extend into the bar-shaped groove 2c to rotate the bolt 4a, and the condition that the movable clamping part 5 blocks the bolt 4a is avoided. Of course, the wrench cannot be rotated directly one turn, but can be rotated repeatedly through a certain angle, but the fastener 4 only needs to be switched between being re-tightened and loosened, and does not need to be rotated for a plurality of turns.

Referring to fig. 6, in some embodiments, two vertical sides of the mounting base 2 in the second horizontal direction are detachably connected with a stopper 2e. More specifically, a detachable manner such as a screw, magnetic attraction, or a buckle may be used. The stopper 2e serves to block the corresponding end of the T-shaped groove 2 b.

When the mounting base 2 can move along the second horizontal direction relative to the adapter block 3, the mounting base 2 and the adapter block 3 can be prevented from being separated due to shielding of the two stop blocks 2 e.

Referring to fig. 1 and 3, in some embodiments, the number of the convex grooves 1a is plural.

When the mounting seat 2 can move along the second horizontal direction relative to the adapter block 3, if the moving range is insufficient, the mounting seat 2, the adapter block 3 and the fastening piece 4 can be moved out of the original convex groove 1a together and connected to the other convex groove 1a, so that the range is increased.
