The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] The first embodiment of the present application is:

[0021] See also Figure 1 to Figure 3 ,in Figure 1 It is a structural schematic diagram of the first embodiment of the utility model. Figure 2 This is a cross-sectional view of the overall structure of the first embodiment of the utility model. Figure 3 It is a partial structural schematic diagram of the first embodiment of the utility model.

[0022] The utility model provides a composite molded PCD turning tool, including a tool rod 101 and a turning tool mechanism, the turning tool mechanism includes a tool head 105, a disc 106, a latch 107, multiple groups of fixing components and locking components, each group of the fixing components includes a resisting block 109, a clamping block 110, a resisting member and a positioning member, the resisting member includes a sliding rod 111 and a spring 112, the positioning member includes a round rod 113 and a ring 114, and the locking component includes a threaded sleeve 115 and a sleeve 116. The above-mentioned solution solves the problem in the prior art that when replacing the tool head, multiple torsion springs need to be deformed, which is very laborious, and the structure is complex and the practicability is low.

[0023] According to the present specific embodiment, the cutter head 105 is fixedly connected to the disc 106 and is located at one side of the disc 106, one end of the latch 107 is fixedly connected to the disc 106, the other end of the latch 107 passes through the knife rod 101 and is slidably connected to the knife rod 101, and multiple groups of the fixing components are respectively arranged inside the knife rod 101, the knife rod 101 has a rectangular groove 102, the abutting block 109 is arranged in the rectangular groove 102, the abutting piece is fixedly connected to the abutting block 109, the knife rod 101 has a groove 103, the block 110 is arranged in the groove 103 and is fixedly connected to the abutting piece, the positioning piece is arranged at one side of the disc 106, and the locking assembly is arranged on the outside of the knife rod 101. When it is used specifically, the latch 107 is inserted into the knife rod 101. Under the resistance of the latch 107, the resistance block 109 drives the resistance member to move into the rectangular groove 102, and the resistance member drives the clamping block 110 to move toward the outside of the knife rod 101 until the latch 107 is completely inserted into the knife rod 101. At this time, under the action of the resistance member, the clamping block 110 moves into the groove 103, and the resistance block 109 is inserted into the latch 107. Then, the clamping block 110 is abutted against the groove 103 by the locking assembly, thereby fixing the latch 107 to the knife rod 101. When the cutter head 105 needs to be disassembled, the locking assembly is moved away from the outside of the clamping block 110, and then the latch 107 is pulled. Under the resistance of the latch 107, the resistance block 109 moves into the rectangular groove 102, thereby separating the latch 107 from the knife rod 101.

[0024] Among them, the sliding rod 111 passes through the knife rod 101 and is slidably connected to the knife rod 101, one end of the sliding rod 111 is fixedly connected to the supporting block 109, and the other end of the sliding rod 111 is fixedly connected to the blocking block 110, and the spring 112 is sleeved on the outside of the sliding rod 111, one end of the spring 112 is fixedly connected to the supporting block 109, and the other end of the spring 112 is fixedly connected to the knife rod 101. When in use, the knife rod 101 resists the supporting block 109 to move into the rectangular groove 102, the supporting block 109 resists the sliding rod 111 to move, and causes the spring 112 to contract, and the sliding rod 111 resists the blocking block 110 to move.

[0025] Secondly, the circular ring 114 is fixedly connected to the knife rod 101 and is located on the outside of the knife rod 101. One end of the circular rod 113 is fixedly connected to the disc 106, and the other end of the circular rod 113 passes through the circular ring 114. When in actual use, when the pin 107 is inserted into the knife rod 101, the circular rod 113 is inserted into the circular ring 114, thereby facilitating the guidance and positioning of the pin 107.

[0026] At the same time, the threaded sleeve 115 is sleeved on the outer side of the tool rod 101 and is threadedly matched with the tool rod 101. The sleeve 116 is sleeved on the outer side of the tool rod 101 and is fixedly connected with the threaded sleeve 115. When in use, the threaded sleeve 115 is rotated. Under the threaded match of the tool rod 101, the threaded sleeve 115 drives the sleeve 116 to move on the outer side of the tool rod 101, and the sleeve 116 is used to support the block 110.

[0027] In addition, the knife rod 101 has a cavity 104 adapted to the pin 107, and the pin 107 has a slot 108 adapted to the abutment block 109. When in use, the cavity 104 is used to insert the pin 107, which is inserted into the slot 108 through the abutment block 109, thereby abutting and fixing the pin 107.

[0028] When using a composite molded PCD turning tool of this embodiment, the latch 107 is inserted into the tool rod 101. Under the resistance of the latch 107, the resistance block 109 drives the slide bar 111 to move into the rectangular groove 102, and the spring 112 contracts. The slide bar 111 drives the block 110 to move to the outside of the tool rod 101 until the latch 107 is completely inserted into the cavity 104. At this time, under the elastic potential energy of the spring 112, the resistance block 109 is inserted into the groove 108, and the slide bar 111 drives the block 110 to move into the groove 103, so that the block 110 is completely fitted with the groove 103. Then, the threaded sleeve 115 is rotated to move the block 110 into the groove 103. Under the thread cooperation, the threaded sleeve 115 drives the sleeve 116 to move outside the tool rod 101, and the sleeve 116 abuts against the block 110, so that the pin 107 is fixed to the tool rod 101. When the tool head 105 needs to be disassembled, the threaded sleeve 115 is rotated in the opposite direction so that the threaded sleeve 115 drives the sleeve 116 away from the outside of the block 110, and then the pin 107 is pulled out. Under the abutment of the pin 107, the abutment block 109 moves into the rectangular groove 102, so that the pin 107 is separated from the tool rod 101. This method can effectively solve the problem in the prior art that when replacing the tool head, multiple torsion springs need to be deformed, which is very laborious, and the structure is complex and the practicability is low.
