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.

[0020] See also Figure 1-5 As shown, a numerically controlled indexing plate that is easy to disassemble comprises an indexing plate base body 1 arranged on the surface of a machine tool, a connecting block 3 is arranged on the surface of the indexing plate base body 1, an adjusting handle body 2 for rotating the connecting block 3 is arranged on one side of the surface of the indexing plate base body 1, pins 4 are fixed on both sides of the surface of the connecting block 3, connecting holes 5 are opened on the surface of the pins 4, limiting mechanisms 6 for limiting the height of a clamping plate 7 are arranged on both sides of the surface of the indexing plate base body 1, and pin holes 8 corresponding to the pins 4 are opened on both sides of the surface of the clamping plate 7. A through hole 9 is provided on the surface of the pin hole 8, and the inner cavity of the clamping plate 7 is provided with a connecting mechanism 10 for connecting the connecting block 3 and the clamping plate 7. A locking mechanism 12 for limiting the operation of the connecting mechanism 10 is provided on one side of the surface of the clamping plate 7. When the utility model is in use, the staff can use the connecting mechanism 10 placed on the side to connect the clamping plate 7 and the connecting block 3. The structure is simple and reliable. In addition, under the action of the locking mechanism 12, the operation of the connecting mechanism 10 can be limited, thereby improving the stability of the connection between the clamping plate 7 and the connecting block 3.

[0021] The limiting mechanism 6 includes a lifting block 61 fixed on both sides of the surface of the dividing plate base body 1 and a slide groove 63 opened on the surface of the clamping plate 7. The surface of the lifting block 61 is rotatably provided with a ball 62, and the ball 62 and the slide groove 63 slide in close contact. In this embodiment, through the arrangement of the lifting block 61, the ball 62 and the slide groove 63, when the clamping plate 7 is placed on the surface of the connecting block 3, the position of the through hole 9 can be made to coincide with the position of the connecting hole 5 with the assistance of the lifting block 61. In addition, under the action of the ball 62 and the slide groove 63, the stability of the clamping plate 7 during rotation is improved.

[0022] The connecting mechanism 10 includes a threaded rod 102 that rotates in the inner cavity of the clamping disk 7, a handle 101 is fixed to one end of the threaded rod 102, a threaded block 103 is meshed on the surface of the threaded rod 102, and connecting rods 104 that can be inserted into the through hole 9 are arranged on both sides of the surface of the threaded block 103. In this embodiment, through the arrangement of the handle 101, the threaded rod 102, the threaded block 103 and the connecting rod 104, the staff can use the handle 101. Under the action of the handle 101, the threaded rod 102 rotates, and the threaded block 103 meshed with the threaded rod 102 can drive the connecting rod 104 to move, thereby allowing the connecting rod 104 to be pulled out or inserted into the connecting hole 5.

[0023] Limit rods 11 are slidably arranged on both sides of the surface of the threaded block 103, and both sides of the limit rods 11 are fixed to the inner cavity of the clamping disk 7. In this embodiment, the limit rods 11 are arranged to provide a limit for the movement of the threaded block 103, thereby improving the stability of the threaded block 103 during movement.

[0024] The locking mechanism 12 includes an extension block 121 fixed to one side of the surface of the clamping disk 7 and a socket 125 opened on the surface of the threaded rod 102. The surface of the extension block 121 is slidably provided with an insertion rod 124, one end of which is fixed with a lifting block 123, and the surface of the insertion rod 124 is sleeved with a spring 122, one end of the spring 122 is fixed to the surface of the extension block 121, and the other end of the spring 122 is fixed to the surface of the lifting block 123. In this embodiment, through the arrangement of the extension block 121, the spring 122, the lifting block 123, the insertion rod 124 and the socket 125, the staff can manually use the lifting block 123 to pull the insertion rod 124 out of the socket 125, so that the threaded rod 102 can rotate, and under the action of the spring 122, the stability of the connection between the insertion rod 124 and the socket 125 is improved.

[0025] Since the working path of the connecting mechanism 10 is a fixed length, after the threaded rod 102 rotates several times, the position of the insertion hole 125 will still coincide with the position of the insertion rod 124.

[0026] The outer diameter of the lifting block 123 is greater than the outer diameter of the insertion rod 124, and the outer diameter of the insertion rod 124 is equal to the inner diameter of the socket 125. In this embodiment, through this arrangement, it is convenient for the staff to use the lifting block 123 to drive the insertion rod 124 to move, and improve the stability of the insertion rod 124 and the socket 125 when they are fitted together.

[0027] Working principle: When in use, the staff can install the indexing plate base body 1 on the surface of the machine tool, and use the adjustment handle body 2 to drive the connecting block 3 and the clamping plate 7 to rotate, so as to operate the workpiece clamped on the surface of the clamping plate 7. When the staff needs to disassemble the clamping plate 7, the staff can first use the locking mechanism 12 to make the lifting block 123 drive the insertion rod 124 to move, thereby releasing the lock on the threaded rod 102. Then the staff can use the twist handle 101. Under the action of the twist handle 101, the threaded rod 102 and the threaded block 103 are engaged, so that the threaded block 103 drives the connecting rod 104 to be pulled out from the connecting hole 5, so that the connection between the clamping plate 7 and the connecting block 3 can be contacted. Then the staff removes the clamping plate 7 to complete the dismantling. When the clamping plate 7 is installed, the staff also uses the locking mechanism 12 and the connecting mechanism 10 to complete the connection between the clamping plate 7 and the connecting block 3, and during installation, under the action of the limit mechanism 6, it can provide assistance for the movement of the clamping plate 7, thereby improving the practicality of the device.
