DETAILED DESCRIPTION

[0022] 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 in 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.

[0023] like Figure 1-4 As shown, the utility model provides a technical solution: a modular turning tool head, comprising a mounting seat 1, a triangular blade 3 and a first bolt 2, a mounting block 4 is fixedly installed on the upper surface of the mounting seat 1, a first mounting hole 10 is opened on the front of the mounting block 4, and a limiting thread 14 is opened on the inner wall of the first mounting hole 10, a reinforcement block 12 is fixedly installed on the front of the triangular blade 3, a first positioning hole 16 is opened on the front of the reinforcement block 12, and a second positioning hole 11 is opened on the front of the triangular blade 3, one end of the first bolt 2 passes through the first positioning hole 16 and the second positioning hole 11 in sequence and extends to the inside of the first mounting hole 10, one end of the first bolt 2 is threadedly connected with the limiting thread 14 opened on the inner wall of the first mounting hole 10, by opening the first positioning hole 16 on the front of the reinforcement block 12 and the second positioning hole 11 on the front of the triangular blade 3, the staff can use the first bolt 2 to firmly mount the triangular blade 3 on the outer surface of the mounting block 4.

[0024] Three chip withdrawal grooves 13 are provided on the outer surface of the triangular blade 3, and three turning heads 15 are provided on the outer surface of the triangular blade 3. By providing the three turning heads 15 on the outer surface of the triangular blade 3, when one turning head 15 is damaged, the staff can rotate the triangular blade 3 by removing the first bolt 2, and then continue to work with the remaining intact turning heads 15. By providing the three chip withdrawal grooves 13 on the outer surface of the triangular blade 3, when any one of the turning heads 15 is used for operation, the debris generated can be discharged through the chip withdrawal grooves 13, avoiding damage to the turning head 15 due to untimely discharge of debris. Three grooves 5 are provided on the outer surface of the mounting block 4, and three hidden grooves 6 are provided on the outer surface of the mounting block 4. By using the three grooves 5 on the outer surface of the mounting block 4, it is more convenient to remove the second bolt 8 from the hidden groove 6.

[0025] The inner bottom wall of each hidden groove 6 is provided with a second mounting hole 9, and the interior of each hidden groove 6 is provided with a second bolt 8. By providing the second mounting hole 9 on the inner bottom wall of each hidden groove 6, the device can be assembled with the tool handle. Each hidden groove 6 hides the second bolt 8, making the device look more beautiful. By using the second bolt 8 to pass through the second mounting hole 9 and threading the bottom end of the second bolt 8 with the threaded hole provided on the outer surface of the tool handle, the device can be firmly assembled with the tool handle. When all three turning heads 15 are damaged, the staff only needs to remove the three second bolts 8 to completely remove the modular turning tool head, and then assemble the new modular turning tool head with the tool handle. A shock-absorbing top rod 7 is fixedly installed on the bottom surface of the mounting seat 1. By installing the shock-absorbing top rod 7 on the bottom surface of the mounting seat 1, the shock-absorbing top rod 7 contacts the damper in the tool handle, which can reduce the vibration of the turning tool head during operation, so that the turning effect can be more perfect.

[0026] Working principle: When one of the turning heads 15 is damaged, the staff uses a tool to rotate the first bolt 2 out of the first mounting hole 10 to a certain length, and then rotates the triangular blade 3 around the first bolt 2 one hundred and twenty degrees. Then the staff uses the tool to fasten the first bolt 2 to the first mounting hole 10. When all three turning heads 15 are damaged, the staff only needs to use the tool to remove the three second bolts 8 in turn to separate the turning head from the tool handle, and then replace it with a new turning head.
