Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a pneumatic chuck device for a tool. Background Art

[0002] As we all know, in the machining industry, tool clamping and fixation is one of the important links to ensure machining quality and efficiency. Traditional pneumatic chucks (i.e. rotary chucks and spring collets) usually need to be tested for clamping force before use.

[0003] The clamping force of traditional pneumatic chucks usually requires manual inspection. Manual inspection relies on the operator's experience and subjective judgment, making it difficult to ensure consistency and accuracy in each inspection. This is not only inefficient, but also difficult to ensure that the optimal clamping state can be achieved every time. In addition, due to the lack of accurate detection methods, the clamping force may be too high and damage the tool, or too low and cause the tool to loosen, thereby affecting the processing accuracy.

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

In this embodiment, the rotary chuck 1 is first placed on the fixed seat 4, and then the first motor 11 is started through the control system 21. The output end of the first motor 11 drives the first bidirectional screw 10 to rotate, and the first bidirectional screw 10 drives the two groups of first sliders 12 to move from both ends toward the middle during the rotation process. A slider 12 drives the first clamping block 13 until the clamping groove 19 on the side wall of the first clamping block 13 realizes the clamping and fixing of the left and right ends of the rotary chuck 1, and then starts the second motor 16. The output end of the second motor 16 drives the second bidirectional screw 15 to rotate. During the rotation process, the second bidirectional screw 15 drives the second slider 17 to move from both ends to the middle. The second slider 17 drives the second clamping block 18 at the top until the clamping groove 19 on the side wall of the second clamping block 18 contacts the front and rear end side walls of the rotary chuck 1, and finally realizes the centering clamping and fixing of the front, rear, left and right ends of the rotary chuck 1. Subsequently, the air supply pipe 6 is connected to the connector 22 on the air pump 20, and then the electric telescopic rod 8 is driven to drive the detection head 5 to descend and descend into the spring collet chuck 2.The pneumatic chuck is activated through the control system 21, causing the spring collet 2 to clamp the test head 5. After each test, the air pressure value and the corresponding clamping force, as well as any abnormal conditions, are recorded and fed back to the control system 21 to test whether the rotary chuck 1 and the spring collet 2 are qualified. The clamping effect under different air pressure conditions is evaluated and the most appropriate air pressure range is determined. If the clamping force is found to be insufficient or excessive, the cause needs to be investigated. It may be due to improper air pressure setting or a problem with the chuck components. The clamping force of the pneumatic chuck can be systematically tested and adjusted accordingly based on the test results to ensure that the pneumatic chuck can provide stable clamping force during the subsequent clamping of the tool.

[0025] Preferably, in this embodiment, the clamping groove 19 is of V-shaped design. The V-shaped clamping groove 19 can provide a better self-locking effect. Even if it is subjected to vibration or impact during the detection process, the fixation of the rotary chuck 1 is not easy to loosen. The V-shaped clamping groove 19 can provide a better positioning function, making it easier to align the rotary chuck 1 with the center position, and the detection head 5 ensures the positioning accuracy with the spring cylinder.

[0026] In actual use, in order to further prevent the first bidirectional screw 10 and the second bidirectional screw 15 from repelling each other, in this embodiment, the first trough body 9 and the second trough body 14 are designed to be staggered up and down. The staggered design separates the movement trajectories of the two bidirectional screws, and each operates independently without affecting each other.

[0027] During actual use, it is further convenient to prevent the first slider 12 and the second slider 17 from rotating. In this embodiment, the first slot body 9 and the second slot body 14 are both rectangular in design. The rectangular design can effectively limit the rotational freedom of the slider in the slot body, ensuring that the first slider 12 and the second slider 17 can only move in a straight line along the predetermined track.

[0028] In actual use, in order to further ensure the supporting strength of the support frame 7, in this embodiment, the support frame 7 is L-shaped. The L-shaped structure can effectively resist torsional force, so that the support frame 7 is not easily deformed when subjected to external force.

[0029] In actual use, the stability and accuracy of the operation of the first motor 11 and the second motor 16 are further guaranteed. In this embodiment, the first motor 11 and the second motor 16 are both servo motors. The servo motors can control position, speed and torque with high precision. The servo motors use closed-loop control and have good stability. They can avoid problems such as stalling and vibration, thereby ensuring the stability and accuracy of the operation of the first motor 11 and the second motor 16.

[0030] Preferably, in this embodiment, the control system 21 is a PLC controller, and the PLC can be programmed through programming software, so that the control system 21 can flexibly adjust the control logic according to different requirements.

[0031] In actual use, in order to further ensure the support stability of the workbench 3, in this embodiment, support legs 23 are installed at the four corners of the bottom end of the workbench 3. The four support legs 23 can evenly distribute the weight of the workbench 3 to the four fulcrums, reducing the load on a single fulcrum and making the entire workbench 3 more stable.

[0032] In order to explain in detail the possible application scenarios, technical principles, specific solutions that can be implemented, and the purpose and effects of this application, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings.
