[0001] The utility model relates to the technical field of tool processing equipment, in particular to a tool clamping device for a numerical control processing center. Background Art

[0002] With the advancement of CNC machining technology, automated and batch metal product processing can be achieved. In the metal manufacturing process of CNC machining centers, tools are needed to drill and grind the surface of metal devices. They are usually in the form of drill rods. Therefore, a fixture is needed to clamp the tool to ensure stability during the processing, thereby ensuring the quality of metal processing.

[0003] After searching, the Chinese patent application publication number CN212444372U discloses a tool clamping device, including a tool disc, the end face of the tool disc is provided with a clamping column for placing the tool arranged along the circumference of the tool disc, the clamping column includes a fixed end and an open end, and the fixed end is fixedly connected to the tool disc.

[0004] A tool clamping device in the above patent has the following shortcomings: although the device can improve the firmness of the connection by arranging the first magnet and the second magnet to adsorb the tool, the positions of the first magnet and the second magnet on the device are fixed. Therefore, when the tool is smaller than the distance between the two second magnets, the tool will be offset to one side and the adsorption effect will be poor, thereby affecting the precision during processing. The first magnet and the second magnet on the device are fixed and installed by bolts. When affected by vibration during processing, the bolts are prone to loosening. If it cannot be detected in time, the clamping tightness will be weakened and the tool will easily fall off. Utility Model Content

Therefore, when the tool is smaller than the distance between the two second magnets, the tool will be offset to one side and the adsorption effect will be poor, thereby affecting the precision during processing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tool clamping device for a CNC machining center, comprising a cylinder and a tool body, wherein the tool body is located in the cylinder, two first rubber rings are symmetrically arranged in the cylinder, mounting holes are opened at both ends of the cylinder, and clamping mechanisms are arranged in the two mounting holes;

The cutter body smaller than the cylinder can be clamped and installed through the first rubber ring. The first rubber ring can reduce the vibration generated during mechanical processing, keep the cutter body stable, avoid processing errors, and achieve high-precision processing. Finally, the cylinder can be sealed and installed through the sealing ring.

[0009] Optionally, the two sliding columns and the two insertion rods are all slidably installed in corresponding installation holes.

[0010] By adopting the above technical solution, two sliding columns and two inserting rods are provided to be slidably installed in corresponding installation holes, thereby playing a role of auxiliary installation.

[0011] Optionally, the two sliding columns and the two insertion rods are of the same size.

[0018] By adopting the above technical solution, a sealing ring can be provided to achieve a sealing installation. Optionally, two sensors are symmetrically fixedly installed on the cylinder, both of which are infrared sensors, and both of which are arranged in parallel with two corresponding nuts. By adopting the above technical solution, when the nut becomes loose, the displacement of the nut can be detected by the sensor, and a signal is then sent to the prompt light installed on the CNC machining center, and then the prompt light is turned on, which can remind the operator to tighten the nut in time to ensure the stability of the clamping plate and prevent the knife body from falling off.
