Description

Technical Field

[0001] This utility model relates to a drilling and tapping machine, and in particular to a tooling fixture for a drilling and tapping machine. Background Technology

[0002] A tapping and drilling machine typically performs tapping and drilling operations on a workpiece by changing the tap and drill bit. Accordingly, a fixture is required to hold and fix the workpiece. Generally, a mounting base with multiple convex grooves and multiple clamping blocks can be used as the fixture. The workpiece is placed on the mounting base, and the position of the clamping blocks within the convex grooves is adjusted to accommodate different workpieces. The clamping blocks act on the edges of the workpiece to press and fix it. If multiple locations on a workpiece need tapping / drilling, the above-mentioned fixture becomes cumbersome. After completing one tapping / drilling operation, the clamping blocks need to be released, the workpiece position adjusted, and then the workpiece re-clamped and fixed. Therefore, a bench vise and a two-axis linear module are also used as fixtures. The bench vise clamps and fixes the workpiece, and the two-axis linear module adjusts the position of the workpiece in both the X and Y axes so that the tapping / drilling location is directly below the tap / drill bit. This type of fixture has a more complex structure and is less stable during the tapping / drilling process. Utility Model Content

[0004] This application provides a tooling fixture for a dual-purpose drilling and tapping machine, comprising:

[0005] The placement platform has a convex groove on its top surface in a first horizontal direction;

[0006] The mounting base is placed on the placement platform, with a fixing clamp on the top surface and a T-shaped groove on the bottom surface in a second horizontal direction perpendicular to the first horizontal direction.

[0007] The adapter block includes: a lower block that holds the narrower portion of the convex groove, and an upper block that holds the narrower portion of the T-groove;

[0008] The fastener, a bolt, has its threaded shaft inserted into the adapter block. The bolt nut is located in the wider part of the T-slot, fitting against the two first connecting surfaces of the T-slot. The nut is located in the wider part of the convex groove, is restricted from rotation, and can fit against the two second connecting surfaces of the convex groove.

[0009] The movable clamping part is slidably connected to the top surface of the mounting base;

[0010] A threaded rod, threadedly connected to the mounting, acts on the movable clamping part, enabling the movable clamping part and the fixed clamping part to clamp the workpiece.

[0012] In some embodiments, the bolt nut is an external hexagon; the mounting base has two vertical sides in the first horizontal direction with strip grooves that connect to the wider portion of the T-shaped groove.

[0013] In some embodiments, the mounting base is detachably connected to two vertical sides in the second horizontal direction with a stop block, which is used to block the corresponding end of the T-slot.

[0014] In some embodiments, the threaded rod enables the movable clamping portion and the fixed clamping portion to clamp the workpiece by having its end abut against the movable clamping portion.

[0015] In some embodiments, both the movable clamping part and the fixed clamping part have notches on their clamping surfaces, and the two notches are aligned in the sliding direction of the movable clamping part.

Unless otherwise specified, the embodiments in this application can be combined with each other.

[0033] Please see Figure 1 and Figure 2 A tooling fixture for a dual-purpose drilling and tapping machine includes a placement platform 1, a mounting base 2, an adapter block 3, a fastener 4, a movable clamping part 5, and a threaded rod 6.

[0034] The top surface of the placement platform 1 has a convex groove 1a. The narrower portion of the convex groove 1a is at the top and extends through the top surface of the placement platform 1, while the wider portion is at the bottom. The convex groove 1a is oriented in a first horizontal direction.

[0035] Mounting base 2 is placed on the placement platform 1. Its top surface has two protrusions, one serving as a fixing clamp 2a and the other for subsequent connection of the threaded rod 6. Its bottom surface has a T-slot 2b. The narrower portion of the convex slot 1a extends downwards and through the bottom surface of the mounting base 2, while the wider portion is upwards. The T-slot 2b is oriented in a second horizontal direction, which is perpendicular to the first horizontal direction. These two horizontal directions correspond to the X-axis and Y-axis, respectively.

[0036] Please see Figure 2 and Figure 3 The adapter block 3 includes a lower block 3b and an upper block 3a. The lower block 3b is held within the narrower portion of the convex groove 1a. The lower block 3b and the narrower portion are of equal width, allowing the mounting base 2 and the adapter block 3 to move together relative to the placement table 1 in a first horizontal direction. The upper block 3a is held within the narrower portion of the T-shaped groove 2b. That is, the upper block 3a and the lower block 3b intersect in a cross shape, with the portion of the upper block 3a extending beyond the lower block 3b fitting against the top surface of the placement table 1. The upper block 3a and the narrower portion are also of equal width, allowing the mounting base 2 to move relative to the adapter block 3 in a second horizontal direction. In summary, the mounting base 2 can move relative to the placement table 1 in both the first and second horizontal directions.

[0037] Fastener 4 consists of bolt 4a and nut 4b.

[0038] Please see Figure 2 and Figure 5 For bolt 4a, the threaded rod passes through the adapter block 3, and the nut is located in the wider part of the T-slot 2b, fitting against the two first connecting surfaces 2b1 of the T-slot 2b. That is to say, the height of the upper block 3a is slightly less than the height of the narrower part of the T-slot 2b, and under the action of the bolt 4a's own weight, the nut fits against the two first connecting surfaces 2b1.

[0039] Please see Figure 2Nut 4b is located in the wider portion of the convex groove 1a and is restricted from rotation. More specifically, nut 4b can be a square nut 4b, the width of which is the same as the width of the wider portion. Nut 4b can fit against the two second connecting surfaces 1a1 of the convex groove 1a. That is, the height of the lower block 3b is slightly less than the height of the narrower portion of the convex groove 1a. When bolt 4a is rotated, nut 4b, because its rotation is restricted, can only move up and down. Moving it upward allows it to fit against the two second connecting surfaces 1a1. By moving nut 4b upward, bolt 4a and nut 4b respectively press against the first connecting surface 2b1 and the second connecting surface 1a1, thus fixing the mounting base 2 relatively to the placement platform 1. Conversely, by moving nut 4b downward, fastener 4 is loosened, and the mounting base 2 can still move relative to the placement platform 1 in the first horizontal direction and the second horizontal direction to adjust its position.

[0040] Obviously, it is also necessary to be able to rotate bolt 4a.

[0041] Please see Figure 2 and Figure 4 In some embodiments, the nut of bolt 4a can be an internal hexagonal socket, and the top surface of mounting base 2 has a strip groove 2c that connects to the wider portion of T-shaped groove 2b.

[0042] Please see Figure 2 The movable clamping part 5 is slidably connected to the top surface of the mounting base 2. More specifically, the top surface of the mounting base 2 may have a groove 2d, in which a linear guide rail can be installed, and the movable clamping part 5 is installed on the mounting slider that matches the linear guide rail.

[0043] The workpiece is clamped by the movable clamping part 5 and the fixed clamping part 2a. Correspondingly, the bottom surface of the movable clamping part 5 can be in contact with the top surface of the mounting base 2, and the top surface of the movable clamping part 5 can be on the same plane as the top surface of the fixed clamping part 2a. The movable clamping part 5 and the fixed clamping part 2a have the same length in the second horizontal direction. The installation position of the movable clamping part 5 on the mounting slider is set so that the clamping surface of the movable clamping part 5 and the clamping surface of the fixed clamping part 2a can be completely aligned.

[0044] Please see Figure 4 and Figure 5 In some embodiments, both the movable clamping part 5 and the fixed clamping part 2a have notches 5a on their clamping surfaces, and the two notches 5a are aligned in the sliding direction of the movable clamping part 5. More specifically, the notches 5a may be located at the middle position of the clamping surfaces.

[0045] When the workpiece is thin and narrow, the movable clamping part 5 and the fixed clamping part 2a will interfere with the downward movement of the drill bit / tap after clamping the workpiece. A notch 5a is designed so that the machining position of the workpiece can be mapped to the notch 5a, thus avoiding interference.

[0046] Please see Figure 1 The threaded rod 6 is threadedly connected to the mounting. More specifically, a cylindrical nut 4b matching the threaded rod 6 is mounted on the corresponding protrusion. The threaded rod 6 acts on the movable clamping part 5, enabling the movable clamping part 5 and the fixed clamping part 2a to clamp the workpiece.

[0047] Please see Figure 2 In some embodiments, there are two T-slots 2b. Correspondingly, there are also 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 accordingly, the threaded rod 6 and the linear guide rail can correspond to the positions between the two T-slots 2b, and are completely offset from the two T-slots 2b.

[0048] In some embodiments, the threaded rod 6 enables the movable clamping portion 5 and the fixed clamping portion 2a to clamp the workpiece in a first manner by having its end rotatably connected to the movable clamping portion 5. That is, the movable clamping portion 5 slides by rotating the threaded rod 6. When it is necessary to clamp the workpiece, the threaded rod 6 is rotated until the movable clamping portion 5 and the fixed clamping portion 2a clamp the workpiece, making it difficult for the threaded rod 6 to rotate further.

[0049] In some embodiments, a second way in which the threaded rod 6 enables the movable clamping part 5 and the fixed clamping part 2a to clamp the workpiece is by having its end abut against the movable clamping part 5. That is, the movable clamping part 5 is slidable manually. When it is necessary to clamp the workpiece, the movable clamping part 5 is first slid manually until the movable clamping part 5 and the fixed clamping part 2a initially clamp the workpiece; then the threaded rod 6 is rotated until its end abuts against the movable clamping part 5, making it difficult for the threaded rod 6 to rotate further.

[0050] The usage process of this application is as follows: First, place the workpiece on the top surface of the placement seat, between the movable clamping part 5 and the fixed clamping part 2a; then, clamp the workpiece with the movable clamping part 5 and the fixed clamping part 2a; then, move the mounting seat 2 relative to the placement table 1 along the first horizontal direction and along the second horizontal direction to adjust the position; finally, tighten the fastener 4 to fix the mounting seat 2 relative to the placement table 1.

[0051] If we combine the embodiments where "the nut of bolt 4a can be an internal hexagon" and "there are two T-slots 2b", it is clear that the movable clamping part 5 may block bolt 4a, thus affecting the step of "tightening the fastener 4 and fixing the mounting base 2 relative to the placement platform 1".

[0052] Please see Figure 5 In some embodiments, based on the embodiment where "there are two T-slots 2b", the nut of the bolt 4a can be an external hexagon, and the mounting base 2 has strip grooves 2c on both vertical sides in the first horizontal direction, the strip grooves 2c connecting to the wider part of the T-slots 2b.

[0053] Compared to the embodiment where "the nut of bolt 4a can be an internal hexagon," a wrench can be inserted into the slot 2c to turn bolt 4a, thus avoiding the situation where the movable clamping part 5 blocks bolt 4a. Of course, the wrench cannot be turned one full turn directly, but can only be turned repeatedly at a certain angle. However, fastener 4 only needs to be switched between tightening and loosening, and does not need to be turned multiple times.

[0054] Please see Figure 6 In some embodiments, the mounting base 2 is detachably connected to two vertical sides in the second horizontal direction with stoppers 2e. More specifically, detachable methods such as screws, magnets, or clips can be used. The stoppers 2e are used to block the corresponding end of the T-slot 2b.

[0055] When the mounting base 2 can move relative to the adapter block 3 in the second horizontal direction, the two stops 2e can prevent the mounting base 2 and the adapter block 3 from separating.

[0056] Please see Figure 1 and Figure 3 In some embodiments, there are multiple convex grooves 1a.

[0057] When the mounting base 2 can move relative to the adapter block 3 in the second horizontal direction, if the range of movement is insufficient, the mounting base 2, adapter block 3, and fastener 4 can be moved out of the original convex groove 1a and connected to another convex groove 1a to increase the range.
