Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a welding fixture for integral PCD tool tips. Background Technology

[0002] In the field of superhard tool manufacturing, polycrystalline diamond (PCD), with its ultra-high hardness, excellent wear resistance, and thermal conductivity, has become the core material for manufacturing high-precision drill bits. Meanwhile, the cemented carbide matrix, due to its good toughness and strength, is often used as the supporting structure for the PCD cylinder. A reliable connection between the two requires a welding process, where coaxiality accuracy is a key indicator determining the machining performance and service life of the PCD cylinder. If the coaxiality deviation between the PCD cylinder and the cemented carbide matrix is ​​too large after welding, it will lead to uneven stress during drill cutting, not only reducing the surface finish of the workpiece but also increasing the risk of tool breakage. Therefore, this welding process holds an irreplaceable position in superhard tool production.

[0003] However, existing welding technology for PCD cylinders and cemented carbide substrates requires that the actual manufacturing diameter of the PCD cylinder be enlarged by 0.3-0.5 mm compared to the theoretical design diameter to avoid misalignment during manual docking. This enlargement margin accounts for 15%-20% of the total PCD raw material usage, resulting in an increase of one-fifth in PCD material cost for each batch of drill bits produced. This leads to significant material costs in the production of small-diameter PCD cylinders. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an integral PCD tool tip welding fixture. This fixture uses an adjustable base to calibrate and coaxially connect the base and the PDC drill bit, thereby reducing material waste.

The Z-axis moving seat is located on top of the Y-axis moving seat, and the left-side cooling plate is located on top of the Z-axis moving seat. The Y-axis moving seat can drive the Z-axis moving seat to move horizontally along the length direction, and the Z-axis moving seat can drive the left-side cooling plate to move vertically along the height direction. The upper surface of the left-side cooling plate is fixedly connected to the bottom of the base clamping seat. The inner cavity of the base clamping seat and the upper surface of the drill bit clamping seat are both provided with V-shaped grooves.

[0006] Furthermore, the Y-axis moving seat includes a Y-axis fixed seat and a Y-axis moving disk. The Y-axis fixed seat is fixedly connected to the upper surface of the second moving seat. The Y-axis moving disk is slidably disposed on the upper surface of the Y-axis fixed seat. A Y-axis fine-tuning screw capable of pushing the Y-axis moving disk to move horizontally along the length direction of the Y-axis fixed seat is provided on the back side of the Y-axis fixed seat.

[0007] Furthermore, a Y-axis limiting block is fixedly installed on the front of the Y-axis fixed base, and a Y-axis limiting rod is fixedly installed on the front of the Y-axis moving disk. The front end of the Y-axis limiting rod extends forward to the outside of the Y-axis limiting block, and a horizontal limiting groove is provided inside the Y-axis limiting block to allow the Y-axis limiting rod to move horizontally.

[0008] Furthermore, the Z-axis moving base includes a Z-axis moving disk and a Z-axis fixed base. The upper surface of the Z-axis moving disk is fixedly connected to the cooling plate on the left side, and the lower surface of the Z-axis fixed base is connected to the Y-axis moving base. The Z-axis fixed base is provided with a Z-axis fine-tuning screw that drives the Z-axis moving disk to move vertically.

This eliminates the need for manual adjustment of the base, solving the problem of misalignment that easily occurs during traditional manual docking. Therefore, it is not necessary to increase the actual diameter of the PCD cylinder by 0.3-0.5mm, avoiding the problem of increasing the cost of PCD material by one-fifth, which would otherwise lead to higher costs. Furthermore, the V-groove in this fixture can accommodate PCD cylinders of different diameters, so this fixture can also be used normally in the production of small-diameter PCD cylinders.

[0017] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0018] See appendix Figure 1-4As shown, an integral PCD tool tip welding fixture includes a chassis 1. A slide rail assembly 2 is fixedly mounted on the upper surface of the chassis 1. A first movable seat 3 is slidably disposed on one side of the slide rail assembly 2, and a second movable seat 4 is slidably disposed on the other side of the slide rail assembly 2. The slide rail assembly 2 consists of two parallel slide rails, and both the second movable seat 4 and the first movable seat 3 can move horizontally along the surfaces of the two slide rails. The horizontal movement of the first movable seat 3 and the second movable seat 4 on the surfaces of the two slide rails is X-axis movement.

[0019] The second movable seat 4 is equipped with an adjustment component on its top, and a base clamping seat 9 for holding the base is provided on the top of the adjustment component. The first movable seat 3 is equipped with a connecting seat 5, which has an I-shaped vertical section. Both the connecting seat 5 and the adjustment component are equipped with cooling plates 10 on their tops. The upper surface of the right cooling plate 10 is equipped with a mounting plate 8. One side of the upper surface of the mounting plate 8 is equipped with a drill clamping seat 81 corresponding to the base clamping seat 9. The other side of the upper surface of the mounting plate 8 is equipped with an elastic fixing member 82 for fixing the PCD cylinder. The elastic fixing member 82 consists of a fixing seat, a parallel section, and a fixing block. The fixing seat is fixedly connected to the upper surface of the mounting plate 8. The fixing block is in contact with the PCD cylinder. When the fixing block is moved, the PCD cylinder is placed into the inner cavity of the drill clamping seat 81. Because moving the fixing block can deform the parallel section and generate elastic force, when the fixing block is released, the parallel section can release the elastic force, so that the fixing block is reset and the PCD cylinder is fixed, thus achieving clamping.

[0020] The adjustment assembly includes a Y-axis moving seat 6 and a Z-axis moving seat 7. The Z-axis moving seat 7 is located on top of the Y-axis moving seat 6, and the left cooling plate 10 is located on top of the Z-axis moving seat 7. The Y-axis moving seat 6 can drive the Z-axis moving seat 7 to move horizontally along the length direction, and the Z-axis moving seat 7 can drive the left cooling plate 10 to move vertically along the height direction. The upper surface of the left cooling plate 10 is fixedly connected to the bottom of the base clamping seat 9. The inner cavity of the base clamping seat 9 and the upper surface of the drill bit clamping seat 81 are both provided with V-shaped grooves.

[0021] By setting up the cooling plate 10, after the base and the PCD cylinder are placed in the base clamping seat 9 and the drill bit clamping seat 81 respectively, the elastic fixing member 82 fixes the PCD cylinder through its own elasticity. The operator can then move the base in the X, Y, and Z axes by adjusting the position of the second moving seat 4 and the Y-axis moving seat 6 and Z-axis moving seat 7 in the adjustment assembly. This achieves precise alignment between the base and the PCD cylinder without the need for manual adjustment of the base, solving the problem of misalignment that is easy to occur when manually connecting the base. Therefore, it is not necessary to increase the actual diameter of the PCD cylinder by 0.3-0.5mm, avoiding the problem of increasing the cost of PCD material by one-fifth, which would otherwise lead to higher costs. Furthermore, the V-groove in the fixture can accommodate PCD cylinders of different diameters, so the fixture can also be used normally in the production of small-diameter PCD cylinders.

[0022] Both sides of the interior of the two cooling plates 10 are provided with flow holes 11, and the outer side wall of the cooling plate 10 is provided with a connecting hole that communicates with the flow holes 11. By providing the flow holes 11, when the flow holes 11 inside the two cooling plates 10 are connected to external cooling equipment through the connecting hole, the cooling equipment injects coolant into the flow holes 11 for flow, thereby reducing the temperature of the cooling plate 10. When the substrate and the PCD cylinder are welded, the two cooling plates 10 can provide auxiliary heat dissipation.

[0023] Furthermore, the Y-axis moving seat 6 includes a Y-axis fixed seat 62 and a Y-axis moving disk 63. The Y-axis fixed seat 62 is fixedly connected to the upper surface of the second moving seat 4. The Y-axis moving disk 63 is slidably disposed on the upper surface of the Y-axis fixed seat 62. A Y-axis fine-tuning screw 61 is provided on the back of the Y-axis fixed seat 62, which can push the Y-axis moving disk 63 to move horizontally along the length direction of the Y-axis fixed seat 62.

[0024] When the Y-axis fine-tuning screw 61 is rotated, the Y-axis fine-tuning screw 61 can push the Y-axis moving disk 63 to move along the length direction of the Y-axis fixed seat 62 through the thread, so that the base clamping seat 9 can be adjusted in the Y-axis direction.

[0025] Furthermore, a Y-axis limiting block 64 is fixedly installed on the front of the Y-axis fixed base 62, and a Y-axis limiting rod 65 is fixedly installed on the front of the Y-axis moving disk 63. The front end of the Y-axis limiting rod 65 extends forward to the outside of the Y-axis limiting block 64, and a horizontal limiting groove is provided inside the Y-axis limiting block 64 for the Y-axis limiting rod 65 to move horizontally.

[0026] By setting a horizontal limiting groove, when the Y-axis moving disk 63 moves, the Y-axis moving disk 63 will drive the Y-axis limiting rod 65 to move synchronously in the Y-axis limiting block 64. When the Y-axis limiting rod 65 moves to either end of the horizontal limiting groove, the horizontal limiting groove will limit the Y-axis limiting rod 65 to prevent the Y-axis moving disk 63 from falling off due to excessive movement.

[0027] Furthermore, the Z-axis moving base 7 includes a Z-axis moving disk 73 and a Z-axis fixed base 72. The upper surface of the Z-axis moving disk 73 is fixedly connected to the left cooling plate 10, and the lower surface of the Z-axis fixed base 72 is connected to the Y-axis moving base 6. The Z-axis fixed base 72 is provided with a Z-axis fine-tuning screw 71 that drives the Z-axis moving disk 73 to move vertically. The front end of the Z-axis fine-tuning screw 71 extends to the outside of the Z-axis fixed base 72. The surface of the Z-axis fixed base 72 is provided with a Z-axis limiting rod 75. A Z-axis limiting plate 74 corresponding to the Z-axis limiting rod 75 is fixedly installed on one side of the front of the Z-axis moving disk 73. The Z-axis limiting plate 74 is provided with a vertical limiting groove that allows the Z-axis limiting rod 75 to move vertically.

[0028] By rotating the Z-axis fine-tuning screw 71, the Z-axis fine-tuning screw 71 starts the vertical movement of the Z-axis moving disk 73, so that the base clamping seat 9 drives the base to move along the Z-axis. When the Z-axis moving disk 73 moves vertically, the Z-axis moving disk 73 will drive the Z-axis limiting rod 75 to slide vertically inside the Z-axis limiting plate 74. When the Z-axis limiting rod 75 moves to any end of the vertical limiting groove, the vertical limiting groove will limit the Z-axis limiting rod 75 to prevent the Z-axis moving disk 73 from falling off due to excessive movement.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
