It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 3, a general tool for processing a guide piston includes a base plate 10, a slider 20, a workpiece support block 30, a positioning pin 40, a pressure plate 50, a fastening drop bolt 60, and a return spring 70.
The upper surface of the workpiece support block 30 is formed with a V-shaped support groove 31, and the support groove 31 is used for placing and supporting the guide piston. The V-shaped structure of the supporting groove 31 can be used for guiding pistons with different outer diameter sizes, and the applicability is strong. The workpiece supporting block 30 is disposed on the slider 20, the workpiece supporting block 30 slides along with the slider 20, and the slider 20 is slidably disposed on the base plate 10 back and forth along the X direction, so that the workpiece supporting block 30 can move along the X direction, thereby achieving position adjustment to more accurately dispose the workpiece.
When the tool is used specifically, the setting direction of the guide piston is the X direction, so that the tool is suitable for adjusting the position of a designed workpiece. Therefore, the center line of the support groove 31 is formed in the Y direction, and the support groove 31 extends in the X direction.
Based on the cylindrical structural characteristic of the guide piston, in order to ensure the centering effect in the workpiece setting process, the structure and the shape of the support groove 31 are bilaterally symmetrical with the center line thereof as the stacking axis.
In some embodiments, the universal tool further comprises a pressure plate 50, wherein the pressure plate 50 is used for pressing and fixing the guide piston.
In order to adapt to workpieces with different outer diameters, a pressing groove 51 for pressing and holding the workpieces and having a V-shaped shape is formed on the pressing plate 50.
In order to help the workpiece to be fixed after press-fitting the workpiece and ensure that the workpiece is stably held, the pressing plate 50 is provided with fastening bolts 60 for fixing it to the base plate 10, the fastening bolts 60 pass through the pressing plate 50, and the ends are threadedly coupled to the workpiece supporting block 30.
The fastening bolt 60 is screwed to the workpiece support block 30 to advance and push the pressing plate 50 to perform a clamping operation.
Further, in some embodiments, the workpiece support 30 and the platen 50 are configured to fit well and make intimate contact when clamped in place. A first table surface 32 is formed on the workpiece supporting block 30, and the first table surface 32 is divided into two parts and respectively formed on the two side edges of the supporting groove 31, the first table surface 32 is perpendicular to the Y direction, a second table surface 52 is formed on the pressing plate 50, the second table surface 52 is divided into two parts and respectively formed on the two side edges of the pressing groove 51, and the second table surface 52 is perpendicular to the Y direction.
When the workpiece is arranged and clamped, the workpiece is positioned between the workpiece support 30 and the pressure plate 50, and the pressure plate 50 and the workpiece support 30 are pushed to be relatively close by the rotation of the fastening bolt 60, so that the clamping and fixing of the workpiece are realized. In some cases, where the outer diameter of the workpiece is relatively small, the first and second lands 32 and 52 come together to effect extreme closure between the workpiece support 30 and the platen 50.
Further, in order to help the pressing plate 50 to reset in the clamping process, a return spring 70 is sleeved on the fastening bolt 60, the return spring 70 is a compression spring, one end of the return spring 70 abuts against the workpiece supporting block 30, and the other end of the return spring abuts against the pressing plate 50. Further, one end of the return spring 70 abuts against the first table 32, and the other end abuts against the second table 52.
