[0002] The diamond cutting insert includes a base and a blade. The base has a raised rib along the outer edge of the disc. The raised rib has several dovetail grooves evenly distributed around its circumference. An inverted dovetail wedge is provided between two adjacent dovetail grooves. A reinforcing rib is provided in a ring between the root of the raised rib and the bottom of the grooves. The blade is pressed and sintered and fixed to the raised rib formed by the dovetail grooves, dovetail wedges and reinforcing ribs. After the diamond insert is worn, it needs to be repaired and reused using a work platform in order to reduce the processing wear and processing cost of the diamond insert.

[0003] However, this type of work platform has the following problems in practical use:

[0018] Compared with related technologies, the PCD diamond crescent end mill and cutting tool repair platform provided by the present invention has the following beneficial effects:

[0019] 1. This invention employs a rotating seat and a rotating block, solving the problem of inconvenient angle adjustment and limited tool processing capabilities during the use of the grinding holder. By tightening the threaded rod, the threaded rod pushes the bearing three downwards, thereby causing the bearing three to push the clamping block to slide, facilitating the fixation of the diamond end mill. By tightening the limit nut, the rotating block is rotated to a suitable angle and limited, causing the rotating block to drive the concave block to rotate, which in turn causes the concave block to drive the threaded rod and clamping block to rotate, facilitating the adjustment of the grinding angle of the diamond end mill. By tightening the limit bolt, the sliding lifting column is slid to a suitable height and limited, while the lifting column drives the rotating block to rotate. The sliding seat facilitates the adjustment of the height of the concave block and clamping block, thus facilitating the adjustment of the diamond end mill's height and improving its performance. Rotating the first rotating wheel causes the first lead screw to rotate, which in turn causes the first nut seat to slide. The first nut seat then causes the second connecting frame to slide, facilitating the adjustment of the position of the second connecting frame and clamping block. Simultaneously, the bottom surface of the second connecting frame is equipped with sliders and ball bearings, improving its stability during sliding. Rotating the second rotating wheel causes the second lead screw to slide, which in turn causes the second nut seat and sleeve to slide, facilitating the adjustment of the lateral position of the diamond end mill and resulting in better grinding performance.

[0020] This invention starts a servo motor, which drives pulley one to rotate. Pulley one drives pulley two to work via a belt. Pulley two drives the gearbox to rotate. Through the set speed regulator and gearbox, the speed can be adjusted from - revolutions per minute to - revolutions per minute, thereby improving grinding efficiency.

[0021] This invention utilizes an arc-shaped block and a limiting post to solve the problem that grinding wheels are usually fixed to a connecting shaft with bolts and an outer protective cover, making disassembly cumbersome and inefficient during replacement. When the grinding wheel needs to be disassembled, the sliding handle moves the arc-shaped block, which in turn moves the limiting ring, facilitating the separation of the grinding wheel from the arc-shaped block. This allows for quick and easy disassembly of the grinding wheel, making it highly practical. During installation, the grinding wheel is engaged with the limiting post, and the sliding handle moves the arc-shaped block and the limiting ring. The telescopic rod and spring push the rectangular block, which in turn moves the limiting block and the arc-shaped block, allowing the grinding wheel to be installed easily.

[0022] In summary, this invention utilizes a screw rod to push the bearing three downwards, which in turn pushes the clamping block to slide, facilitating the fixation of the diamond end mill. By tightening the limit nut, the rotating block is rotated to a suitable angle and limited, causing the concave block to rotate. This, in turn, causes the concave block, screw rod, and clamping block to rotate, allowing for adjustment of the diamond end mill's grinding angle. The speed regulator and gearbox allow for adjustment of the rotation speed from - revolutions per minute to - revolutions per minute, improving grinding efficiency. When the grinding wheel needs to be removed, the sliding handle moves the arc-shaped block, which in turn moves the limit ring, facilitating separation of the grinding wheel from the circular block and enabling quick and easy removal of the grinding wheel.

[0045] The working principle of the PCD diamond crescent end mill and cutting tool repair platform provided by this invention is as follows:

[0046] Implementation steps for the first innovation point:

[0047] Step 1: By turning the threaded rod 41, the threaded rod 41 pushes the bearing 3 42 to slide downward, thereby causing the bearing 3 42 to push the clamping block 43 to slide, which facilitates the fixing of the diamond end mill. By turning the limit nut 39, the rotating block 37 is rotated to a suitable angle and limited. The rotating block 37 drives the concave block 40 to rotate, thereby causing the concave block 40 to rotate the threaded rod 41 and the clamping block 43, which facilitates the adjustment of the grinding angle of the diamond end mill.

The effect is good.

[0049] Step 3: By rotating the first rotating wheel 21, the first rotating wheel 21 drives the first lead screw 20 to rotate, thereby causing the first lead screw 20 to slide the first nut seat 22. The first nut seat 22 drives the second connecting frame 23 to slide, which facilitates the adjustment of the position of the second connecting frame 23 and the clamping block 43. At the same time, the bottom surface of the second connecting frame 23 is provided with a slider 29 and a ball bearing 30, which improves the stability of the second connecting frame 23 when sliding.

[0050] Implementation steps for the second innovation point:

[0051] Step 1: By starting the servo motor 10, the servo motor 10 drives the pulley 11 to rotate. The pulley 11 drives the pulley 2 16 to work through the belt. The pulley 2 16 drives the gearbox 5 to rotate. Through the speed regulator 4 and the gearbox 5, the speed can be adjusted from 0-1400 rpm to 0-3500 rpm, thereby improving the grinding efficiency.

[0052] The third innovation point implementation steps:

[0053] Step 1: When it is necessary to disassemble the grinding wheel 8, slide the sliding handle 50.

This makes it easy and quick to disassemble the grinding wheel 8 and is very practical.
