Description

Technical Field

[0001] This utility model belongs to the field of drill bit processing technology, specifically relating to a grooving positioning mechanism for drill bit processing. Background Technology

[0002] During the machining process, drill bits need to be grooved to form chip removal grooves and cutting edges. Existing drill bit grooving processes often use a rotary clamping mechanism to clamp and position the tail of the drill bit, and then use a diamond grinding wheel to grind the chip removal grooves on the drill bit. However, the rotary clamping mechanism can only support the clamping part of the drill bit tail. When the machining point is far from the support position, the pressure of the drill bit machining part will be transmitted to the clamping part of the drill bit. Due to the cantilever effect, it is easy to bend and deform, resulting in a decrease in grooving accuracy, or even scrapping the drill bit. Utility Model Content

[0003] This utility model provides a slotting positioning mechanism for drill bit processing, which can provide close-range support and limit the real-time processing part of the drill bit during the drilling process, so as to avoid the drill bit being deformed by pressure.

[0004] This utility model provides the following technical solution: a grooving positioning mechanism for drill bit processing, including a drill bit flat placement groove plate, a drill bit limiting sleeve fixedly connected to one side of the drill bit flat placement groove plate, a chip removal groove opened on the inner wall of the drill bit flat placement groove plate, the chip removal groove being inclined downwards, an extension support block being detachably connected to the bottom end of the drill bit flat placement groove plate, a lead screw being threadedly connected to the inner wall of the extension support block, vertical support plates being rotatably connected to both ends of the lead screw, and a track support plate being slidably connected to the bottom end of the extension support block.

[0005] The drill bit is fixedly connected to the side wall of the flat slot plate with a connecting plate, and the connecting plate is bolted to the extension support block.

[0006] The vertical support plate has a connecting bushing fixedly connected to its inner wall, and the connecting bushing is rotatably connected to the lead screw.

[0007] One end of the lead screw is fixedly connected to a drive motor.

[0008] The lead screw is fitted with two folding sleeves on its outer side. One end of the folding sleeve is fixedly connected to the adjacent connecting shaft sleeve, and the other end of the folding sleeve is fixedly connected to the extension support block.

[0009] The side wall of the extension support block is fixedly connected to a side positioning plate, and the side positioning plate is detachably connected to the track support plate.

[0010] The bottom end of the track support plate is fixedly connected to an installation plate, and the installation plate has installation holes.

[0011] The beneficial effects of this utility model are: by using the drill bit flat slot plate and drill bit limiting sleeve to support the drill bit, in conjunction with the extension support block to support the drill bit flat slot plate and drill bit limiting sleeve, and the screw to adjust the position of the extension support block, it is possible to provide close support and limit the real-time processing part of the drill bit during the drill bit processing process, avoid the drill bit from being deformed by pressure, and improve the stability of the drill bit in the slotting process.

Detailed Implementation

[0017] Please see Figures 1-3 The present invention provides the following technical solution: a grooving positioning mechanism for drill bit processing, including a drill bit flat placement groove plate 1, a drill bit limiting sleeve 11 fixedly connected to one side of the drill bit flat placement groove plate 1, a chip removal groove 12 opened on the inner wall of the drill bit flat placement groove plate 1, the chip removal groove 12 is inclined downward, an extension support block 2 is detachably connected to the bottom end of the drill bit flat placement groove plate 1, a lead screw 21 is threadedly connected to the inner wall of the extension support block 2, both ends of the lead screw 21 are rotatably connected to a vertical support plate 22, and a track support plate 3 is slidably connected to the bottom end of the extension support block 2.

[0018] In this implementation scheme: the tail of the drill bit rod passes through the drill bit flat slot plate 1 and the drill bit limiting sleeve 11 and is clamped in the rotating clamping mechanism. In the initial state, the drill bit flat slot plate 1 and the extension support block 2 are located at the vertical support plate 22 near the drive motor 23. The end of the drill bit protrudes a short distance from the drill bit limiting sleeve 11 and extends into the drill bit flat slot plate 1, and the upper half of the drill bit protrudes from the drill bit flat slot plate 1. As the diamond grinding wheel grinds and slots the drill bit, the slotting position gradually approaches the tail of the drill bit. The drive motor 23 drives the lead screw 21 to rotate, following the progress of the drill bit slotting, driving the drill bit flat slot plate 21 to rotate. Plate 1 and extension support block 2 move towards the tail of the drill bit. With the support of the drill bit flat slotting plate 1 and the drill bit limiting sleeve 11, along with the support of the extension support block 2 and the extension support block 2, and the adjustment of the position of the extension support block 2 by the screw 21, the drill bit can be supported and limited near the machining area during the drilling process. Through multi-point support of the drill bit tail clamping mechanism and the drill bit flat slotting plate 1, excessive force on the drill bit tail clamping mechanism is avoided, preventing deformation of the drill bit due to pressure, thus improving the stability of the drill bit during the grooving process. To improve the accuracy of drill bit grooving, after one process is completed, the drive motor 23 drives the lead screw 21 to rotate in the opposite direction, causing the extension support block 2 to reset, ready for use in the next process. The internal slot dimensions of the drill bit flat slotting plate 1 and the drill bit limiting sleeve 11 match the dimensions of the drill bit to be processed. The extension support block 2 plays a supporting role for the drill bit flat slotting plate 1 during the process, preventing deformation of the drill bit flat slotting plate 1 through comprehensive support from below, thereby avoiding a decrease in the support effect for the drill bit due to deformation of the drill bit flat slotting plate 1. In addition, the height of the extension support block 2 itself plays an extension support role. Raise the height of the drill bit flat placement slot plate 1 and the drill bit limiting sleeve 11 so that there is a distance between the drill bit flat placement slot plate 1 and the drill bit limiting sleeve 11 and the lead screw 21 and the vertical support plate 22 below, so as to avoid the rotating clamping mechanism at the tail of the drill bit. In actual production, the height of the extension support block 2 can be adjusted according to the distance between the rotating clamping mechanism and the equipment mounting base plate in the equipment model. The chip removal groove 12 plays the role of removing chips. In actual use, the drill bit flat placement slot plate 1, the drill bit limiting sleeve 11 and the drill bit processing position are continuously flushed with cutting fluid to cool down and accelerate the removal of chips.

[0019] A connecting plate 13 is fixedly connected to the side wall of the drill bit flat slot plate 1, and the connecting plate 13 is bolted to the extension support block 2. The connecting plate 13 facilitates the connection between the drill bit flat slot plate 1 and the extension support block 2. In actual operation, the bolt is inserted into the corresponding hole on the extension support block 2 through the hole on the connecting plate 13. When changing the drill bit model, or when the drill bit flat slot plate 1 and the drill bit limiting sleeve 11 are damaged, the original drill bit flat slot plate 1 and the drill bit limiting sleeve 11 are removed and replaced with new drill bit flat slot plate 1 and drill bit limiting sleeve 11.

[0020] A connecting bushing 221 is fixedly connected to the inner wall of the vertical support plate 22, and the connecting bushing 221 is rotatably connected to the lead screw 21. By setting the connecting bushing 221, the connection between the lead screw 21 and the vertical support plate 22 can be facilitated, so as to realize the mutual rotation between the lead screw 21 and the vertical support plate 22.

[0021] One end of the lead screw 21 is fixedly connected to a drive motor 23; by setting the drive motor 23, the lead screw 21 can be driven to rotate, thereby driving the extension support block 2 to move laterally. When selecting the drive motor 23, it is necessary to meet the requirements of bidirectional drive, step drive, and locking positioning of the output shaft, so as to drive the rotation of the lead screw 21 according to the actual processing requirements.

[0022] Two folding sleeves 24 are fitted on the outer side of the lead screw 21. One end of the folding sleeve 24 is fixedly connected to the adjacent connecting shaft sleeve 221, and the other end of the folding sleeve 24 is fixedly connected to the extension support block 2. By setting the folding sleeves 24, the lead screw 21 can be shielded and protected to prevent debris from entering the thread groove and affecting the rotation of the lead screw 21.

[0023] The side wall of the extension support block 2 is fixedly connected to a side positioning plate 25, which is detachably connected to the track support plate 3. By setting the side positioning plate 25, the extension support block 2 and the track support plate 3 can be locked and positioned. The bolts are screwed into the slots on the side positioning plate 25 to press the track support plate 3 to achieve the positioning function, so as to perform positioning when the equipment is idle.

[0024] A mounting plate 31 is fixedly connected to the bottom of the track support plate 3, and mounting holes 32 are provided on the mounting plate 31. By setting the mounting plate 31, the entire device can be installed on the mounting base plate of the processing equipment, and bolts are used to thread it through the mounting holes 32 to connect with the mounting base plate of the processing equipment.

[0025] The working principle and usage process of this utility model: The tail of the drill bit rod passes through the drill bit flat slot plate 1 and the drill bit limiting sleeve 11 and is clamped in the rotating clamping mechanism. In the initial state, the drill bit flat slot plate 1 and the extension support block 2 are located at the vertical support plate 22 near the drive motor 23. The end of the drill bit protrudes a short distance from the drill bit limiting sleeve 11 and extends into the drill bit flat slot plate 1, and the upper half of the drill bit protrudes from the drill bit flat slot plate 1. As the diamond grinding wheel grinds and grooves the drill bit, the grooving position gradually approaches the tail of the drill bit. The drive motor 23 drives the lead screw 21 to rotate. Following the grooving process of the drill bit, the drill bit flat slot plate 1 and the extension support block 2 move towards the tail of the drill bit. During the drill bit processing, the real-time processing part of the drill bit is supported and limited nearby. By coordinating the drill bit tail clamping mechanism with the drill bit flat slot plate 1 to provide multi-point support for the drill bit, the excessive force on the drill bit tail clamping mechanism is avoided, which would cause the drill bit to deform under pressure.
