Detailed Description

The following description will explain embodiments of the present invention with reference to the accompanying drawings. As shown in fig. 1 and 2: a piston processing fixture capable of realizing rapid positioning comprises a base plate 1, a spigot positioning disc 2 and a supporting seat 3 are arranged on the top end face of the base plate 1, two positioning shafts 4 which are symmetrically distributed are movably connected in the supporting seat 3, the tail end of each positioning shaft 4 is connected with a first linkage frame 5, the first linkage frame 5 is rotatably connected with a horizontal adjusting shaft 6, the horizontal adjusting shaft 6 is in threaded connection with the supporting seat 3, a handle 7 is arranged at the end part of the horizontal adjusting shaft 6, two sets of rapid pressing mechanisms are symmetrically arranged on the top end face of the supporting seat 3, each rapid pressing mechanism comprises a pressing plate 9 connected on the supporting seat 3 through a bolt 8, a spring 10 is sleeved outside the bolt 8 below the pressing plate 9, one end of the pressing plate 9 is connected with a second linkage frame 11, a vertical adjusting shaft 12 is in threaded connection with the middle part of the second linkage frame 11, the top end of the vertical adjustment shaft 12 is also provided with a handle 7,

The working process of the clamp for processing the piston, which can realize quick positioning, of the embodiment of the utility model is as follows: firstly, a piston piece 14 to be processed is placed on a base plate 1, a spigot of the piston 14 is clamped on a spigot positioning disc 2, then a positioning core shaft 13 is inserted into a positioning hole on the piston 14, two ends of the positioning core shaft 13 are ensured to protrude out of the side wall of the piston 14,

the horizontal adjusting shaft 6 is driven to rotate by rotating the handle 7, and the horizontal adjusting shaft 6 is in threaded connection with the supporting seat 3, so that the rotation of the horizontal adjusting shaft 6 can be converted into linear motion along the axial direction of the horizontal adjusting shaft 6, the first linkage frame 5 is driven to move, the positioning shafts 4 arranged at two ends of the first linkage frame 5 can synchronously move towards the direction of the positioning mandrel 13 at the same time, and after the two positioning shafts 4 are simultaneously contacted with the positioning mandrel 13, the positioning mandrel 13 can be driven to drive the piston piece 14 to rotate until the axis of the positioning mandrel 13 is parallel to the first linkage frame 5, namely, the movement of the horizontal adjusting shaft 6 can adjust the posture of the piston piece 14 in the circumferential direction;

after the adjustment is finished, an operator drives the vertical adjusting shaft 12 to rotate in a mode of rotating the handle 7, and then drives the vertical adjusting shaft 12 to move along the axial direction of the operator, the rapid pressing mechanism is of a lever structure, because the bolt 8 only plays a supporting role in the mechanism (the bolt 8 is not in threaded connection with the pressing plate 9, and the bolt 8 can do relative movement in a connecting hole formed in the pressing plate 9), the bolt 8 is matched with the spring 10 sleeved outside the bolt 8, and the bolt 8 is equivalent to a fulcrum of the lever, when the vertical adjusting shaft 12 moves downwards relative to the second linkage frame 11, one end of the second linkage frame 11 is lifted upwards, one end of the pressing plate 9, which is far away from the second linkage frame 11, is pressed downwards, namely, the end of the pressing plate 9 presses the piston member 14 with a proper posture, and positioning and clamping operations of the piston member 14 are realized.

After the processing is finished, the vertical adjusting shaft 12 is rotated reversely, the pressing plate 9 does not apply pressure to the piston piece 14, then the horizontal adjusting shaft 6 is rotated reversely, the two positioning shafts 4 are separated from contact with the outer wall of the positioning mandrel 13, the positioning mandrel 13 is drawn out from the piston piece 14, and the piston piece 14 is taken down from the base plate 1.
