Detailed Description
In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.
As shown in fig. 1-2, a grinding machine fixture for machining comprises an oil cylinder 1 and a tailstock 6, wherein a piston of the oil cylinder 1 is connected with an expansion sleeve 3 through a connecting rod 2, the oil cylinder 1, the tailstock 6 and the expansion sleeve 3 are all fixed on a workbench, a push rod 5 is arranged on the tailstock 6, a transmission rod 7 is fixedly connected onto the connecting rod 2, one end of the transmission rod 7 extends into the tailstock 6 and is in transmission with the push rod 5 through a stroke control structure, the transmission rod 7 is generally arranged below to reduce interference with a part or a workpiece 4 as much as possible, and a protective cover is preferably added on the transmission rod to shield the part or the workpiece.
The stroke control structure comprises a large piston and a small piston, a first oil cavity 9 with a larger diameter and a second oil cavity 12 with a smaller diameter are formed in the tail seat 6, the first oil cavity 9 is communicated with the second oil cavity 12, the large piston is in sealing sliding connection with the inner wall of the first oil cavity 9 and is connected with the transmission rod 7, the small piston is in sealing sliding connection with the inner wall of the second oil cavity 12, the small piston is fixedly connected with one end of the ejector rod 5, the tail ends of the large piston and the transmission rod 7 are arranged on the right side of the first oil cavity 9 at the moment, the transmission rod 7 is required to be provided with a bending part to be connected with the large piston, a communication pipeline between the first oil cavity 9 and the second oil cavity 12 is required to be arranged on the left side, and the purpose is to enable the working direction of the large piston during clamping to be consistent with the working direction of the oil cylinder, so that the ejector rod 5 can be pushed to push the tail end of the workpiece 4.
Still include the driving medium, the driving medium is stay cord 10, and the one end and the transfer line 7 of stay cord 10 are connected, and the stay cord 10 other end passes through reverse wheel and big piston fixed connection for the motion opposite direction of big piston and transfer line 7 can set up big piston on the left side of first oil pocket 9 like this, and the intercommunication pipeline sets up on the right, makes this tailstock 6 structure comparatively clean and tidy.
