DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] As Figure 1 shown in FIG. - 3, a tool holder locking seat for a numerically controlled tool holder that is convenient for installation includes a mounting seat 1. A numerically controlled tool holder main body 3 is provided on the top of the mounting seat 1. Clamping mechanisms 2 are provided on both sides of the surface of the mounting seat 1.

[0022] The clamping mechanism 2 includes a clamping block 201. Mounting grooves 202 are formed on both sides of the inner cavity of the mounting seat 1. The clamping block 201 is located inside the mounting groove 202. A compression spring 203 is fixedly installed on one side of the clamping block 201. The other end of the compression spring 203 is fixedly installed with a connecting plate 204. A push plate 205 is provided on one side of the connecting plate 204. A threaded rod 206 is fixedly installed on one side of the push plate 205. The other side of the threaded rod 206 extends to the outside of the mounting seat 1 and is fixedly installed with a rotating plate 208. Clamping grooves 211 are formed on both sides of the surface of the numerically controlled tool holder main body 3. One side of the clamping block 201 is clamped inside the clamping groove 211.

[0023] The effects achieved by the above components are as follows: By setting the compression spring 203 to push the clamping block 201, one end of the clamping block 201 is clamped inside the clamping groove 211, further playing a role in clamping the numerically controlled tool holder main body 3, facilitating the installation and disassembly of the numerically controlled tool holder main body 3, improving the disassembly and assembly efficiency of the numerically controlled tool holder main body 3. Under the action of the rotating plate 208, it is convenient to manually rotate the threaded rod 206. Then, with the cooperation of the threaded hole 207, the threaded rod 206 drives the push plate 205 to move inside the mounting groove 202 and push the connecting plate 204 to move, so that the connecting plate 204 squeezes the compression spring 203, ensuring the elastic force of the compression spring 203 on the clamping block 201, and thus ensuring that the clamping block 201 is stably clamped inside the clamping groove 211, improving the installation stability of the numerically controlled tool holder main body 3.

[0024] As Figure 3 shown, threaded holes 207 are formed on both sides of the surface of the mounting seat 1. The threaded holes 207 are communicated with the mounting grooves 202. The threaded rod 206 passes through the threaded hole 207 and is threadedly connected to the threaded hole 207.

[0025] The effects achieved by the above components are as follows: By setting the threaded rod 206 and the threaded hole 207 to cooperate with each other to drive the push plate 205 to move, and then the push plate 205 pushes the connecting plate 204 and the clamping block 201, the stability of the clamping block 201 being clamped inside the clamping groove 211 is improved, and thus the installation stability of the CNC tool holder body 3 is improved.

[0026] As Figure 3 shown, a first magnetic block is provided on one side of the connecting plate 204 close to the push plate 205, a second magnetic block is provided on one side of the push plate 205 close to the connecting plate 204, and the first magnetic block and the second magnetic block adsorb each other.

[0027] The effects achieved by the above components are as follows: By setting the first magnetic block and the second magnetic block to cooperate with each other to strengthen the connection between the connecting plate 204 and the push plate 205, and to prevent the separation between the connecting plate 204 and the push plate 205, resulting in the instability of the clamping block 201.

[0028] As Figure 3 shown, limiting grooves 212 are provided on both the front and back of the inner embedding of the installation groove 202, limiting blocks are fixedly installed on both the front and back of the clamping block 201, and the limiting blocks are located inside the limiting grooves 212.

[0029] The effects achieved by the above components are as follows: By setting the limiting grooves 212 and the limiting blocks to cooperate with each other to limit the clamping block 201, the stability of the clamping block 201 when moving inside the installation groove 202 is improved, and thus the clamping block 201 is accurately clamped inside the clamping groove 211.

[0030] As Figure 3 shown, a bottom groove 209 is provided at the bottom of the installation groove 202, one side of the bottom groove 209 communicates with the inside of the installation base 1, and a push rod 210 is fixedly installed at the bottom of the clamping block 201, and the push rod 210 penetrates through the bottom groove 209.

[0031] The effects achieved by the above components are as follows: By setting the push rod 210, it is convenient to move the clamping block 201, and thus it is convenient to move the clamping block 201 out of the inside of the clamping groove 211, facilitating the disassembly of the CNC tool holder body 3.

[0032] As Figure 4 shown, evenly distributed positioning blocks 4 are fixedly installed at the bottom of the inner cavity of the installation base 1, and evenly distributed positioning grooves 5 are provided at the bottom of the CNC tool holder body 3, and the positioning blocks 4 are clamped inside the positioning grooves 5.

[0033] The effects achieved by the above components are as follows: By setting the positioning blocks 4 and the positioning grooves 5 to cooperate with each other to position and install the CNC tool holder body 3, preventing the CNC tool holder body 3 from being installed offset inside the installation base 1 and avoiding affecting the clamping effect of the CNC tool holder body 3.

[0034] The working principle of a numerically controlled tool holder locking seat that is easy to install:

[0035] The compression spring 203 pushes the latch 201 open, so that one end of the latch 201 is clamped inside the clamping groove 211, further playing a role in clamping the numerically controlled tool holder main body 3, facilitating the installation and disassembly of the numerically controlled tool holder main body 3. Under the action of the rotating plate 208, it is convenient to manually rotate the threaded rod 206. Then, under the cooperation of the threaded hole 207, the threaded rod 206 drives the push plate 205 to move inside the installation groove 202 and push the connecting plate 204 to move, so that the connecting plate 204 squeezes the compression spring 203, ensuring the elastic force of the compression spring 203 on the latch 201, and further ensuring that the latch 201 is stably clamped inside the clamping groove 211, improving the installation stability of the numerically controlled tool holder main body 3.

[0036] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
