Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a laser chuck dustproof sealing mechanism. Background Technology

[0002] Laser chucks are mainly used in laser processing equipment and are an important component of laser cutting equipment. They are primarily responsible for fixing and clamping the material to be cut, ensuring stability and precision during the cutting process.

[0003] A large amount of dust is generated during the machining process. If dust enters the chuck, it will cause a decrease in positioning accuracy and may also wear down internal parts, reducing its service life. Therefore, dustproof design is crucial to the reliability and lifespan of pneumatic chucks.

[0004] In chuck rotation, the air distribution plate is typically fixed to the outer ring of the bearing, while the chassis that drives the workpiece rotation is fixed to the inner ring of the bearing. By controlling the air distribution plate with either air supply or de-air supply, the chassis and air distribution plate can be switched between fastened and de-fastened states, thereby controlling the chassis rotation. For example, after machining one side of the workpiece, it needs to be rotated to the other side for machining. At this time, the air distribution plate is not vented, and the chassis can rotate relative to the air distribution plate. When the workpiece needs to be clamped for machining after rotation, it is necessary to ensure that the workpiece is clamped and cannot rotate. At this time, the air distribution plate is vented, and the internal structure causes friction between it and the chassis. The resulting friction prevents the chassis from rotating, thus allowing machining to proceed smoothly.

[0005] However, during the manufacturing process, due to the high level of dust in the environment, dust inevitably gets between the valve train and the chassis, affecting both and causing wear on internal parts, thus reducing their service life. Therefore, a dustproof sealing mechanism is needed to prevent dust from entering. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The purpose of this utility model is to provide a dustproof sealing mechanism for a laser chuck, which solves the problem of the lack of a dustproof sealing mechanism between the existing gas distribution plate and the chassis, which easily causes wear on internal parts and reduces service life. (II) Utility Model Content

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a laser chuck dustproof sealing mechanism, including a base, a bearing is provided in the middle of the base, characterized in that: a chassis is fixedly connected to one side of the inner ring of the bearing by bolts, a gas distribution plate is provided between the chassis and the bearing, the gas distribution plate is fixedly connected to the inner ring of the bearing by bolts, an annular boss is provided on the circumference of the side of the chassis near the gas distribution plate, the annular boss is provided on the outer side of the gas distribution plate, an installation groove is provided on the outer side wall of the gas distribution plate, a rubber dustproof pad is provided between the installation groove and the annular boss, one end of the rubber dustproof pad is inserted into the installation groove, and the other end abuts against the side wall of the annular boss away from the gas distribution plate.

[0010] Preferably, the rubber dustproof pad is L-shaped, and the end of the rubber dustproof pad near the mounting groove is provided with two sets of protrusions. The distance between the top of the protrusion and the bottom is 3.6mm, and the width of the mounting groove is 3mm.

[0011] (III) Beneficial Effects

[0012] The advantages of the laser chuck dustproof sealing mechanism provided by this utility model are as follows:

[0013] 1. By setting an annular boss and a rubber dustproof pad, an alternating barrier structure is formed between the gap between the air distribution plate and the chassis and the external environment, increasing the difficulty for dust to enter the gap between the air distribution plate and the chassis, so that the air distribution plate and the chassis always maintain a good working condition, reducing the wear between the workpieces and extending the service life.

[0014] 2. By setting the mounting groove and the protrusion of the rubber dustproof pad, the rubber dustproof pad is fixed after being inserted into the mounting groove by utilizing the elastic deformation characteristics of rubber. When the rubber ages, it can be simply removed and replaced with a new one, which is highly convenient. Attached Figure Description

[0024] Please see Figure 1-4A dustproof sealing mechanism for a laser chuck includes a base 1, a bearing 2 disposed in the middle of the base 1, a chassis 3 fixedly connected to one side of the inner ring of the bearing 2 by bolts, an air distribution plate 4 disposed between the chassis 3 and the bearing 2, and the air distribution plate 4 fixedly connected to the inner ring of the bearing 2 by bolts. An annular boss 5 is disposed on the circumference of the chassis 3 near the air distribution plate 4, located on the outer side of the air distribution plate 4. An installation groove 6 is formed on the outer sidewall of the air distribution plate 4, and a rubber dustproof pad 7 is disposed between the installation groove 6 and the annular boss 5. One end of the rubber dustproof pad 7 is inserted into the installation groove 6, and the other end abuts against the sidewall of the annular boss 5 away from the air distribution plate 4. By setting the annular boss 5 and the rubber dustproof pad 7, a staggered barrier structure is formed along the path of dust entering the gap between the air distribution plate 4 and the chassis 3, reducing the probability and amount of dust entering between the air distribution plate 4 and the chassis 3, thus improving service life.

[0026] When the laser chuck dustproof sealing mechanism is used, the rubber dustproof pad 7 is first embedded into the mounting groove 6, and the other end of the rubber dustproof pad 7 abuts against the outer side wall of the annular boss 5. Through the alternating arrangement of the annular boss 5 and the rubber dustproof pad 7, a "barrier dam" is formed to prevent dust from entering between the air distribution plate 4 and the chassis 3.
