Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to a waterproof device for a four-axis indexing turntable. Background Art

[0002] The numerical control turntable for the linked processing of three-dimensional parts usually needs to select a cam roller structure indexing plate with high precision and high efficiency. The fourth-axis numerical control turntable is very helpful for industrial production. Its unique advantages make the processing program of the product simpler. It can reduce the processing time of the article. Different from the third axis, the fourth axis has only one rotating axis, that is, it uses this one rotating axis to process and cut the workpiece. Its accuracy is very high and it can very accurately find the processing point of the workpiece to improve the processing efficiency of the workpiece. The movement of the turntable is driven by a servo motor. After being decelerated by a toothed belt, it drives a precision worm and worm pair to make the turntable rotate. After the turntable is connected, there will be a gap on its outer edge, and the gap communicates with the electronic components inside the numerical control turntable. When there is moisture in the processed workpiece, it is easy to flow into the inside along the stream and cause damage to the electronic components. The traditional sealing ring plate is made of hard material and is easy to have rotational friction with the side of the turntable, resulting in the loss of both, and it cannot prevent the entry of moisture, so the waterproof effect is poor.

Then, the spring is matched with the annular array inside the ring gasket to improve its contact elasticity relative to the turntable, so that it can be relatively squeezed and fitted with the turntable body to prevent moisture from entering. Finally, the wear-resistant clamp is fitted with the turntable to reduce its friction loss and increase its service life.

[0005] According to the waterproof device for a four-axis indexing turntable, the outer annular array of the ring frame is provided with a plurality of mounting holes, and the mounting holes are equipped with screws that are rotatably engaged with the shell, so as to facilitate tight fixation between the ring frame and the shell.

[0006] According to the waterproof device for a four-axis indexing turntable, the ring pad is made of rubber to improve the elasticity of the ring pad itself.

[0007] According to the waterproof device for a four-axis indexing turntable, the front side of the control panel is covered with a smooth pad surface to reduce wear during long-term operation.

[0008] According to the waterproof device for a four-axis indexing turntable, the bottom of the bottom plate and the rear of the side plate are fixedly connected with anti-skid pads to improve the stability during placement.

[0009] According to the waterproof device for a four-axis indexing turntable, a plurality of sealing pads are arranged in a circular array on the opposite side of the wear-resistant snap ring, and the sealing pads are relatively extended into the inner wall of the ring pad and are connected and fixed to the spring, thereby improving the connection strength between the wear-resistant snap ring and the ring pad and preventing moisture from entering the spring to cause rust.

[0010] The above scheme has the following beneficial effects:

[0011] In the present utility model, by first fitting and fixing the ring frame with the shell sleeve and then protruding a ring pad on the front part of its inner side to create a height difference, when the turntable body is placed flat, moisture can naturally flow outwards from the ring frame by gravity and will not accumulate. Then, by annularly arranging springs inside the ring pad to improve the contact elasticity between the ring pad and the turntable, it can be relatively pressed and fitted with the turntable body to prevent moisture from entering. Finally, a wear-resistant snap ring is provided to fit with the turntable, reducing its frictional loss and increasing its service life.
