Description

Chuck module for easy multi-channel processing

This creation is related to the chuck module, especially a chuck module that is easy to perform multi-channel processing.

The chuck is a necessary tool for the general machine tool to clamp the workpiece to facilitate the tool to process the workpiece. In order to allow the jaws of the chuck to operate stably and quickly, a substrate is usually set up in terms of structure. There are two channels inside the substrate. The two channels are designed with one in and one out, and then use at least one control valve to control the gas (or It is the flow of oil) in the aforementioned two channels to control the action of the jaws.

However, the aforementioned two channels are traditionally formed by deep hole machining, which is not only difficult in processing, but also can only process straight channels. Although 3D printing can be used to set up non-linear channels, the processing cost is relatively high. In addition, in addition to processing the substrate, there is another way to install an exposed tube for gas flow on the back of the substrate, but the existence of the exposed tube will inevitably increase the thickness of the overall structure of the chuck. Therefore, the structure of the traditional chuck still has room for improvement.

The main purpose of this creation is to provide a chuck module that is easy to perform multi-channel processing to save costs.

Another purpose of this creation is to provide a chuck module whose overall structure is thinner.

In order to achieve the above purpose, the chuck module of this creation includes a base plate, a control valve, a chuck, and a guide plate. The substrate has a first surface and a second surface opposite to the first surface, wherein there is a groove on the second surface, in addition, the substrate has a first through hole, a second through hole, and a third Perforation and a fourth perforation, the first perforation, the second perforation, the third perforation and the fourth perforation all penetrate the first surface and the second surface and communicate with the groove; the control valve is provided on the substrate The first surface has an air supply hole and a return hole, the air supply hole communicates with the first through hole of the substrate, and the return hole communicates with the second through hole of the substrate; the chuck is arranged on the first surface of the substrate and has a An air inlet and an air outlet, the air inlet communicates with the third through hole of the substrate, and the outlet communicates with the fourth through hole of the substrate; the hardness of the guide plate is less than the hardness of the substrate, and the guide plate is arranged on the substrate The groove has an air inlet channel and an air outlet channel. The two ends of the air inlet channel are respectively connected to the first and third through holes of the substrate, and the two ends of the air outlet channel are respectively connected to the second and fourth through holes of the substrate . Thereby, the high-pressure gas provided by the control valve enters the air inlet channel of the guide plate from the air supply hole through the first through hole of the substrate, and then enters the clamp through the third through hole of the substrate and the air inlet hole of the chuck In the head, the chuck can be controlled by the control valve to clamp the workpiece. On the contrary, the high-pressure gas in the chuck enters the air outlet channel of the guide plate from the air outlet hole through the fourth hole of the substrate, and then Return to the control valve through the second perforation of the substrate and the air return hole of the control valve, so that the chuck can be controlled by the control valve to loosen the workpiece, thus completing a cycle.

It can be seen from the above that because the material of the guide plate is less rigid than the material of the substrate, it is convenient to perform multi-channel processing on the guide plate. As for the substrate, it can achieve the effect of thinning while maintaining sufficient strength to save processing. cost.

Preferably, the number of the control valve and the chuck can be adjusted according to actual needs. For example, one control valve is matched with two chucks, that is, one control valve controls the clamping of two chucks at the same time, or two controls The valve is matched with two chucks and controlled in a one-to-one manner.

Preferably, the guide plate can be a whole plate body or a splicing of two large plate bodies and one small plate body. In the latter case, the two plates are assembled together by two pins. The two pins can also help to block the gas at the same time. As for the junction of the two plates, at least one O-ring can be further provided to avoid air leakage.
