[0001] The utility model relates to the technical field of chamfering cutter equipment, in particular to a single crystal diamond chamfering cutter structure. Background Art

[0002] Single crystal diamond tools are the main cutting tools in the field of ultra-precision machining. They can produce extremely high workpiece precision and extremely low surface roughness, achieving mirror finishing.

[0003] At present, the tool shank and tool holder of existing single crystal diamond chamfering tools are mostly integrated. Once the tool head and tool shank are damaged, the chamfering tool needs to be removed from the machine tool for replacement. However, the overall disassembly is relatively complicated, which affects the machine adjustment time, and the overall replacement of the chamfering tool increases the processing cost.

[0004] Therefore, there is an urgent need to provide a single crystal diamond chamfering tool structure whose components can be individually disassembled and replaced. Utility Model Content

[0005] In order to overcome the shortcomings that the tool rod and tool holder of existing single crystal diamond chamfering cutters are mostly integrated, once the cutter head and tool rod are damaged, the chamfering cutter needs to be disassembled and replaced as a whole, which is a relatively complicated process and affects the machine adjustment time. In addition, the overall replacement has a high processing cost. The utility model provides a single crystal diamond chamfering cutter structure whose components can be disassembled and replaced separately.

[0006] To solve the above problem, the utility model adopts the following technical solution: a single crystal diamond chamfering tool structure, including a mounting seat, a mounting sleeve is clamped on the mounting seat, a tool rod is threadedly arranged in the mounting sleeve, a slot is provided at the upper end of the tool rod, and a single crystal blade is arranged in the slot of the tool rod.

[0007] More preferably, a connecting plate is provided on the mounting seat through the mounting frame, a cam is rotatably mounted on the connecting plate, and the cam can be fixed against the mounting sleeve after rotation, a torsion spring is sleeved on one end of the cam, a rocker is fixedly connected to the other end of the cam, a first mounting plate is fixedly connected to the mounting sleeve, a guide plate is provided on the first mounting plate through a limiting plate, a screw is threadedly provided on the guide plate and the first mounting plate, a connecting frame is provided on the guide plate, a block is rotatably provided on the connecting frame through a rotating shaft, and the rocker can be limited when the cam rotates through cooperation between the block and the screw, thereby achieving the purpose of fixing the cam.

[0008] More preferably, mounting holes are provided on both sides of the mounting sleeve, mounting bolts are threadedly provided in the mounting holes, and a clamping block for clamping the mounting sleeve is rotatably provided on the mounting bolts.

[0009] More preferably, the block is arc-shaped.

[0010] More preferably, a limiting clamping plate is clamped on the single crystal blade, one end of a guide rod is fixedly connected to the limiting clamping plate, the other end of the guide rod is in contact with the inner wall of the slot of the tool rod, a second mounting plate is slidably arranged on the guide rod, and an elastic member is connected between the second mounting plate and the limiting clamping plate.

[0011] More preferably, a rubber pad is provided on the side of the limiting clamping plate that contacts the single crystal blade.

[0012] Compared with the prior art, the utility model has the following technical effects: 1. By adopting a threaded setting on the tool rod and the mounting sleeve and the mounting seat being snap-fitted together, the tool rod can be designed to be disassembled separately, which is convenient for partial replacement when the tool rod is damaged, thereby reducing processing costs.

[0013] 2. Fix the cam at a specific angle by rotating the rocker and cooperating with the block and the screw so that the cam rests against the mounting sleeve. This avoids the problem of the chamfering cutter loosening due to the rotation of the mounting sleeve during use.

[0014] 3. By turning the mounting bolt, the clamping block moves inward to clamp the mounting sleeve for reinforcement, thereby improving the firmness of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] See also Figure 1 and Figure 2 A single crystal diamond chamfering tool structure includes a mounting seat 4, a mounting sleeve 3 is clamped on the mounting seat 4, a tool rod 1 is provided with an inner thread of the mounting sleeve 3, and the threaded design of the tool rod 1 is convenient for separate disassembly and replacement. A slot is provided on the upper end of the tool rod 1, and a single crystal blade 2 is provided in the slot of the tool rod 1.

[0026] First, screw the tool rod 1 into the mounting sleeve 3, and then insert the mounting seat 4 through the mounting sleeve 3 to complete the assembly of the single crystal diamond chamfering tool. Then, the assembled single crystal diamond chamfering tool is fixed on the machine tool by driving screws into the four corners of the mounting seat 4 to achieve installation. When the tool rod 1 is damaged during use, the tool rod 1 is twisted in the same direction, and the tool rod 1 moves upward and separates from the mounting sleeve 3 under the action of the thread, so that it can be disassembled separately and the processing cost can be reduced.

[0027] Example 2

[0028] Based on Example 1, please refer to Figure 4-Figure 6The front side of the mounting seat 4 is provided with a connecting plate 6 through a mounting frame 5, and a cam 7 is rotatably mounted on the connecting plate 6. After the cam 7 is rotated, it can be fixed against the mounting sleeve 3. A torsion spring 8 is sleeved on one end of the cam 7, and both ends of the torsion spring 8 are respectively connected to the cam 7 and the connecting plate 6. A rocker 9 is fixedly connected to the other end of the cam 7. A first mounting plate 10 is fixedly connected to the top of the mounting sleeve 3 by screw connection. A guide plate 12 is provided on the first mounting plate 10 through a limiting plate 11. A screw 13 is threadedly arranged on the guide plate 12 and the first mounting plate 10. A connecting frame 14 symmetrically distributed on the left and right is provided on the guide plate 12. A stopper 16 is rotatably arranged on the connecting frame 14 through a rotating shaft 15. By cooperating with the stopper 16 and the screw 13, the rocker 9 can be limited when the cam 7 is rotated, thereby achieving the purpose of fixing the cam 7.

[0029] The rocker 9 is rotated to make the cam 7 rest against the installation sleeve 3. Then, the rotated rocker 9 squeezes the stopper 16 to rotate upward and is located between the stopper 16 and the screw 13. The stopper 16 and the screw 13 limit the rocker 9 to fix the cam 7. The cam 7 is used to stabilize the installation sleeve 3 to avoid the problem of the chamfering cutter loosening due to the rotation of the installation sleeve 3 during use.

[0030] See also Figure 3 The left and right sides of the mounting sleeve 3 are provided with mounting holes 1801 which are symmetrically distributed up and down. The mounting holes 1801 are provided with mounting bolts 18 in a threaded manner. A clamping block 17 for clamping the mounting sleeve 3 is rotatably provided on the mounting bolts 18. The clamping block 17 is arc-shaped and can better clamp the mounting sleeve 3. After the mounting sleeve 3 is installed in the mounting seat 4, the mounting bolts 18 are rotated to move the clamping block 17 inward to clamp the mounting sleeve 3 for reinforcement, thereby improving the connection firmness.

[0031] See also Figure 7 A limiting clamping plate 21 is clamped on the single crystal blade 2, and one end of a guide rod 20 is fixedly connected to the limiting clamping plate 21, and the other end of the guide rod 20 is in contact with the inner wall of the slot of the tool rod 1. A second mounting plate 19 is slidably arranged on the guide rod 20, and an elastic member 22 is connected between the second mounting plate 19 and the limiting clamping plate 21, and the elastic member 22 is sleeved on the guide rod 20. A rubber pad 23 is arranged on the side of the limiting clamping plate 21 that contacts the single crystal blade 2. When the limiting clamping plate 21 clamps the single crystal blade 2, the rubber pad 23 is used to protect the single crystal blade 2 to prevent the limiting clamping plate 21 from crushing the single crystal blade 2.

[0032] When installing the single crystal blade 2, the single crystal blade 2 is inserted between the limiting clamp 21 and the clamping slot. The limiting clamp 21 is moved to a suitable position according to the thickness of the single crystal blade 2 and then the single crystal blade 2 is pressed and fixed. In this way, the installation of the single crystal blade 2 is completed, which ensures the stability of use while facilitating disassembly.
