Oil (gas) pressure chuck structure with rapid decoupling

This creation department relates to an oil (gas) pressure chuck structure with rapid de-clamping, especially a designer of a gasoline compression chuck control structure for a fast processing of a professional processing tool and a loosely processed workpiece.

According to the traditional patent application No. M316122 "Gas and hydraulic rotary chucks for machine tools" (please refer to the first figure, which is taken from the first figure of the case), it is generally used in the fixed seat (20). The pressure conveying hole (215) of the fixing seat body (21) serves as a returning device for resetting the piston seat (30) and uses a plurality of compression springs supported on the piston seat (30) as a recovery device to input pressure with the pressure conveying hole. That is, the piston seat (30) can be pushed forward. When the pressure is released, the piston seat (30) is automatically reset by the elastic force of the compression spring (25), and the fork type pull ring (40) and the collet are urged. (80) Displace the front to remove the clamped workpiece/tool; see the structure described in the previous case as follows: 1. Why the fixed seat (20) is rotatable but on the outer diameter The pressure delivery hole (215) is provided, which is a structural device that is not feasible. 2. The collet (80) is placed in the tapered groove (71) of the inclination body (70), and is connected to the small diameter end of the collet (80) by a connecting member, even if the collet (80) cannot be axially Disengagement; this type of connection will cause the collet (80) to be easily disengaged and thrown under high-speed rotation, causing danger. 3. The structure of automatically retracting the piston seat (30) by the elastic force of the compression spring (25) causes the fork type pull ring (40) and the collet (80) to be displaced forward, and the workpiece can be taken out. Actuation mode, in which, if the release force of the compression spring (25) is fatigued, the release collet (80) will not be effectively activated, resulting in difficulty in removing the clamped workpiece. The leader. 4. The fork type pull ring (40) is formed by a group of four fork blocks (41), and is arranged on each sleeve portion of each of the fork blocks (41) which is worn by the rotary seat. There are a plurality of slots extending through the circumferential wall of the ring and are fixedly connected with the connecting member (60); the structure is complicated, and the manufacturing cost and assembly are complicated.

For this reason, according to the traditional practice of patents, there are many problems in the structure of the patent. For this reason, the creator has the experience of specializing in the manufacture of automobile-specific tools, and in order to improve its lack, it is only to study this. The improvement of the product-like products finally finally created the structure of the gasoline press chuck with the rapid de-clamping, which can effectively solve the lack of the above-mentioned traditional habits.

Therefore, the main purpose of this creation is to provide an oil (gas) pressure chuck structure with rapid decoupling, mainly using a plurality of screws to interlock the convex rotating fixed plate with the tapered cylindrical clamp. The structure is provided with a fixed seat set and a pressure control movable piston seat on the periphery of the combination of the convex rotating fixed plate and the tapered cylindrical clamp, and the device is combined with the cone-shaped tube to compress the cone and release the force. The inner diameter of the cone brakes the sliding sleeve and is fixed by a fixing ring. Finally, an oil (gas) cylinder body is sleeved to form a gasoline compression chuck structure; wherein the fixed seat group and the pressure control piston seat and The deep groove ball bearing and the one-way thrust ball bearing are used as the lateral and outer radial rotations in the outer diameter groove between the cone inner diameter brake sliding sleeve seat and the fixing ring and the fixed seat group and the pressure control piston seat. The pulley arrangement has enabled the various components to achieve the effect of sliding in the radial direction and the axial direction.

The secondary purpose of this creation is to provide a hydraulic (gas) pressure chuck structure that directly uses the oil (gas) pressure control method to push the pressure control activity piston seat, and the convex type is fixed. Disk and cone collet and pressure control movable piston seat and cone The inner diameter brake sliding sleeve seat, the fixing ring and the like are integrally combined into a rotatable structure, and are fixed by the oil (gas) cylinder body and fixedly fixed with the fixing seat group, thereby Use oil (gas) pressure to control the inlet and outlet of the oil inlet and outlet, even if the oil pressure directly pushes or releases the pressure control piston seat, so as to push or release the brake sleeve and control the cone clamp The function of the bundle clamping or loosening of the workpiece is characteristic of it.

Another purpose of this creation is to provide an oil (gas) pressure chuck structure with high speed clamping force and stable clamping force and good precision of processing. The oil (gas) pressure direct control method is adopted to quickly make pressure control activities. The displacement of the piston seat in the axial direction can obtain a high clamping force, and the combination structure of the air force can achieve a high clamping stability when the chuck is moved in the axial direction or the radial direction, thereby processing The accuracy of the object is enhanced and is characterized by it.

In summary, there is an oil (gas) pressure chuck structure with rapid de-clamping, which can achieve the stability of rapid stripping and the high precision of clamping force. The structural features and purposes of the present invention, as well as a detailed description of the drawings, can provide a deeper understanding of the structure of the creation.
