Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a drilling machine fixture with a multi-specification adaptable structure. Background Technology

[0002] A drilling machine is a machine tool primarily used to machine holes in workpieces using a drill bit. Its key feature is that the workpiece remains stationary while the cutting tool rotates. It is widely used in machinery manufacturing and repair industries. The drilling machine completes the drilling operation through the rotation and axial movement of the drill bit. Its core functions include drilling, reaming, boring, countersinking, and tapping.

[0003] When drilling, the workpiece needs to be clamped. Clamping tools include three-jaw and four-jaw chucks, or the most common flat-jaw vises. These clamps can only clamp workpieces with regular shapes and cannot clamp workpieces of arbitrary shapes. Therefore, we propose a drilling machine fixture with a multi-specification adaptable structure. Utility Model Content

[0004] This utility model provides a drilling machine fixture with a multi-specification adaptable structure, which has the advantage of clamping workpieces of any shape and solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A drilling machine fixture with a multi-specification adaptable structure is designed, including multiple second mounting seats and at least one first mounting seat. Both the first and second mounting seats can be detachably mounted on the machine tool slot plate. One end of the first mounting seat is inclined upward with an inclined block. Each first mounting seat is provided with a clamping block above it. The bottom of the clamping block is provided with a vertical surface perpendicular to the inclined block. Below the vertical surface is a rectangular cavity with a width greater than the width of the inclined block. The top of the inclined block is placed in the rectangular cavity, so that the clamping block can slide back and forth along the inclined block. This application also includes an adjusting bolt parallel to the vertical surface. The bottom of the adjusting bolt is threadedly connected to the inclined block, and the top of the adjusting bolt is movably placed in the top of the clamping block.

[0006] Preferably, each of the second mounting bases has a stop at one end vertically.

[0007] Preferably, the clamping block and the tilting block are connected by a guide mechanism, which includes guide grooves provided on both sides of the top of the clamping block and parallel to the vertical plane, and L-shaped locking blocks are detachably provided on both sides of the tilting block, with the top of the L-shaped locking blocks slidably placed in the guide grooves.

[0008] Preferably, an elastic mechanism is provided between the top of the rectangular cavity and the top of the inclined block. Driven by the elastic mechanism, the inclined block is always placed at the bottom of the rectangular cavity. The elastic mechanism includes a return spring, with both ends of the return spring placed in spring grooves. The spring grooves are respectively provided on the surface of the inclined block and the inner surface of the rectangular cavity.

[0009] Preferably, there is a gap between the bottom of the clamping block and the machine tool slot plate.

[0010] Preferably, the top of the clamping block is an inclined surface.

[0011] Compared with the prior art, in use, the second mounting base is placed around the workpiece to be processed and positions the workpiece, while the first mounting base is also located on the side of the workpiece and fixed. The clamping block can be driven to press against the workpiece by turning the adjusting bolt with a wrench. This fixing method is simple and reliable. The workpiece can be firmly fixed by simply turning the adjusting bolt by hand. Moreover, both the first and second mounting bases are easy to disassemble and adjust, so that workpieces of any shape can be clamped. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 7 This utility model provides a technical solution: a drilling machine fixture with a multi-specification adaptable structure, including multiple second mounting seats 5 and at least one first mounting seat 4. The first mounting seat 4 and the second mounting seat 5 can be detachably mounted on the machine tool slot plate 1. The machine tool slot plate 1 is the most common component of machine tool equipment, and its main purpose is to install various fixtures, etc. A slider is provided in the T-slot on the surface of the machine tool slot plate 1. When installing the first mounting seat 4 and the second mounting seat 5, the first mounting seat 4 and the slider are fastened by the second locking bolt 9, and the second mounting seat 5 and the slider are fastened by the first locking bolt 7.

[0023] In practical application, the second mounting base 5 is placed around the workpiece to be processed, meaning that the shape of the space enclosed by multiple second mounting bases 5 is consistent with the shape of the workpiece to be processed. This allows the workpiece to be positioned when placed in this space. To better ensure contact between the second mounting base 5 and the workpiece, each second mounting base 5 has a vertical stop 6 at one end. The side of the stop 6 is circular, and the top of the stop 6 has a guide slope, which makes it easier to place the workpiece.

[0024] The second mounting base 5 mentioned above is mainly for positioning the workpiece, while the first mounting base 4 is for locking the workpiece. There is at least one first mounting base 4, which can be increased or decreased according to the actual situation in actual use. The composition of the first mounting base 4 will be described in detail below, such as... Figure 3 As shown, one end of the first mounting base 4 is inclined upward with an inclined block 2, which is a rectangular block. Each first mounting base 4 has a clamping block 3 above it. The bottom of the clamping block 3 has a vertical surface 18 perpendicular to the inclined block 2. Below the vertical surface 18 is a rectangular cavity 13 with a width greater than the width of the inclined block 2. Figure 4 and Figure 5As shown, the top of the inclined block 2 is placed inside the rectangular cavity 13. Since the width of the rectangular cavity 13 is greater than the width of the inclined block 2, there is room for movement between the inclined block 2 and the rectangular cavity 13. This allows the pressing block 3 to slide back and forth along the inclined block 2. When the pressing block 3 slides down along the inclined block 2, the bottom of the pressing block 3 moves forward. When the pressing block 3 slides up along the inclined block 2, the bottom of the pressing block 3 retracts in the opposite direction. like Figure 4 and Figure 5 As shown, each clamping block 3 corresponds to an adjusting bolt 8, such as... Figure 5 As shown, the vertical plane 18 is parallel to the adjusting bolt 8. The bottom of the adjusting bolt 8 is threadedly connected to the inclined block 2, while the top of the adjusting bolt 8 is movably placed inside the top of the clamping block 3. The screw head of the adjusting bolt 8 is located on the end surface of the clamping block 3. Thus, when the adjusting bolt 8 is rotated, since the adjusting bolt 8 is parallel to the vertical plane 18, the adjusting bolt 8 can drive the clamping block 3 to slide downward or move upward along the inclined block 2, thereby realizing the clamping block 3 advancing forward or retracting. like Figure 2 and Figure 7 As shown, after the workpiece is placed, the first mounting base 4 is also located on the side of the workpiece and fixed. At this time, the adjusting bolt 8 can be turned with a wrench. Figure 4 and Figure 5 As shown, the clamping block 3 and the adjusting bolt 8 are inclined upwards. This design has advantages because the adjusting bolt 8 is inclined upwards, so there is a certain distance between the screw head of the adjusting bolt 8 and the machine tool slot plate 1. When the wrench is connected to the screw head, the wrench can rotate within this distance, avoiding the situation where the bolt is horizontal and the wrench is in contact with the machine tool slot plate 1, making it inconvenient to tighten the adjusting bolt 8. Instead, this design allows the operator to continuously tighten the adjusting bolt 8 with a wrench, which is convenient for operation. The adjusting bolt 8 is preferably a hexagonal head bolt, and the corresponding wrench is L-shaped. When the adjusting bolt 8 is tightened, the end of the clamping block 3 can be tightly pressed against the surface of the workpiece to fix the workpiece. This fixing method is simple and reliable, eliminating the need for cylinders or other telescopic components to drive the workpiece and removing the need for a pneumatic control system. During use, the workpiece can be firmly fixed simply by turning the adjusting bolt 8 by hand. Moreover, the first mounting base 4 and the second mounting base 5 are easy to disassemble and adjust, allowing for clamping operations on workpieces of any shape.

[0025] Furthermore, this application makes further improvements to the clamping block 3 and the tilting block 2, thereby enhancing the stability between them. Firstly, the clamping block 3 and the tilting block 2 are connected by a guide mechanism, such as... Figure 4As shown, the guiding mechanism includes guide grooves 11 located on both sides of the top of the clamping block 3 and parallel to the vertical plane 18. L-shaped locking blocks 12 are detachably provided on both sides of the inclined block 2. The tops of the L-shaped locking blocks 12 slide within the guide grooves 11. The inclined block 2 and the L-shaped locking blocks 12 are specifically fastened together by bolts. It should be noted that the clamping block 3 can move along the inclined block 2 even without the guiding mechanism, but with the guiding mechanism, the clamping block 3 is more stable due to the cooperation of the L-shaped locking blocks 12 and the guide grooves 11. To enable the clamping block 3 to automatically rebound, an elastic mechanism is provided between the top of the rectangular cavity 13 and the top of the inclined block 2. Driven by this elastic mechanism, the inclined block 2 remains at the bottom of the rectangular cavity 13. The elastic mechanism includes a return spring 15, with both ends of the return spring 15 positioned within spring grooves 10. The spring grooves 10 are respectively located on the surface of the inclined block 2 and the inner surface of the rectangular cavity 13. Figure 5 As shown, at this time, the clamping block 3 is located at the top of the tilting block 2.

[0026] Based on the above embodiments, it should be further explained that the bottom of the clamping block 3 is provided with a horizontal surface 17, and there is a gap 14 between the bottom of the clamping block 3 and the machine tool slot plate 1 (specifically, there is a gap 14 between the horizontal surface 17 and the machine tool slot plate 1). This gap is used for the clamping block 3 to move up and down.

[0027] Based on the above embodiments, further optimization is possible. The top of the clamping block 3 is an inclined surface 16, which facilitates the placement of the workpiece. Furthermore, the clamping block 3 has tooth marks on the side closest to the workpiece.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
