After drilling, the piston is removed, rotated, and clamped in the groove again. The connection between the piston and the tool is relatively cumbersome, and it needs to be disassembled and assembled twice, which has low processing efficiency. Utility Model Content

[0033] Attached Figure 1 To Attachment Fig.10 As the best embodiment of the piston processing auxiliary device, the present application is further described in detail below in conjunction with the accompanying drawings.

[0034] A piston processing auxiliary device includes a base plate 1 and vertical plates 2 arranged vertically at both ends of the base plate 1. The base plate 1 is provided with a plurality of waist-shaped holes 101. The base plate 1 and the vertical plates 2 form a U-shaped frame. Bolts pass through the waist-shaped holes 101 to fix the base plate 1 to the processing platform of a drilling machine.

[0035] A telescopic control mechanism 6 is fixedly connected to one of the vertical plates 2. The telescopic control mechanism 6 adopts an electric cylinder or a hydraulic telescopic rod. The movable part of the telescopic control mechanism 6 is connected to a horizontally arranged top rod 5. The top plate 3 is arranged at the end of the top rod 5. The top plate 3 is arranged between the two vertical plates 2.

[0036] The piston 17 is horizontally placed between the two vertical plates 2, and is fixed by supporting it with a push rod 5, and then the pin hole of the piston 17 is drilled.

[0037] Since the piston 17 is provided with two symmetrically arranged pin holes, since the holes are drilled only from one direction, the length of the drill bit is required, and eccentricity is also prone to occur. Therefore, basically, the piston 17 is turned over after the pin holes are drilled on one side of the piston 17, and the pin holes on the other side are drilled.

[0038] In order to facilitate the flipping of the piston 17, in this embodiment, a turntable 7 is rotatably connected to the vertical plate 2 arranged opposite to the top plate 3, and a positioning mechanism is provided between the turntable 7 and the vertical plate 2. The positioning mechanism adjusts the turntable 7 to two states: rotation and fixed. The push rod 5 is rotatably connected to the top plate 3.

[0039] Furthermore, a connecting column 301 is protruded on one side of the top plate 3 facing the top rod 5, a pressure plate 501 is provided on one side of the top rod 5 facing the top plate 3, a pressure ring 4 is provided on the outer cover of the pressure plate 501, and the pressure ring 4 is fixedly connected to the connecting column 301. A rotating bearing is provided between the pressure plate 501 and the pressure ring 4, and the two are rotatably connected.

[0040] The top plate 3 and the contact surfaces of the rotating disk 7 and the piston 17 are provided with anti-skid rubber pads, and the piston 17 is clamped between the top plate 3 and the rotating disk 7 .

[0041] After drilling a hole on one side of the piston 17 , remove the positioning mechanism, then rotate the turntable 7 to rotate the piston 17 180°, then install the positioning mechanism, lock the turntable 7 , and drill the pin hole on the other side of the piston 17 .

[0042] The specific positioning mechanism and related components are arranged as follows: a control plate 10 is protrudingly provided on the side of the turntable 7 facing away from the top plate 3 , a slot 13 is protrudingly provided on the vertical plate 2 , and the control plate 10 is rotatably arranged inside the slot 13 .

[0043] The slot 13 is provided with a vertically arranged through hole on the circumferential surface, and the control panel 10 is provided with two relatively symmetrically arranged sockets 1003 on the circumferential surface. The positioning mechanism is an insertion rod 16, which passes through the through hole on the circumferential surface of the slot 13 and is inserted into one of the sockets 1003.

[0044] The angle between the two jacks 1003 is 180°. After the insertion rod 16 is removed, the turntable 7 can rotate. After the turntable 7 rotates 180°, the jacks 1003 are coaxially arranged with the through holes on the slot 13. Then the insertion rod 16 is inserted to lock the turntable 7.

[0045] A convex shaft 1002 is convexly provided on the side of the control panel 10 facing away from the top plate 3 , and the convex shaft 1002 is rotatably connected to the vertical plate 2 .

[0046] The convex shaft 1002 is passed through the outside of the vertical plate 2, and a cover 14 is provided on the outside of the vertical plate 2. The cover 14 is covered on the convex shaft 1002, and the cover 14 and the convex shaft 1002 are connected by a coaxially arranged connecting bolt 15. The contact part between the connecting bolt 15 and the cover 14 is an optical axis, so that the two are connected in rotation.

[0047] This arrangement allows the turntable 7 to be detachable, making assembly and subsequent maintenance easier.

[0048] Support seats 701 are protruding on both sides of the turntable 7, and a horizontally arranged push rod 801 is inserted inside the support seat 701. A chuck 8 is fixed to one end of the push rod 801 facing the axis of the turntable 7. A first spring 9 is sleeved on the push rod 801 and is located between the chuck 8 and the support seat 701.

[0049] The piston 17 is clamped between the two chucks 8 . The inner end surface of the chuck 8 is an arc surface, which abuts against the outer wall of the piston 17 . The first spring 9 pushes the chuck 8 to squeeze the piston 17 , further improving the fixing effect of the piston 17 .

[0050] If the operator starts drilling without inserting the plunger 16 after the piston 17 rotates during the operation, the piston 17 will rotate under the impact, causing safety hazards such as flying knives. In order to avoid this phenomenon, in this embodiment, the control panel 10 is provided with a spring cavity 1001 inside, and a clamping rod 11 with a spring seat 1101 and a second spring 12 are provided inside the spring cavity 1001. The clamping rod 11 is axially arranged along the radial direction of the spring cavity 1001, and the end of the clamping rod 11 is passed through the outside of the control panel 10.

[0051] Two symmetrically arranged locking holes 1301 are provided on the circumferential surface of the slot 13 , and the locking rod 11 is inserted into one of the locking holes 1301 .

[0052] The outer diameter of the clamping rod 11 is larger than that of the inserting rod 16. Thus, when rotating the piston 17, the inserting rod 16 needs to be removed first, and then inserted into the clamping hole 1301, and the clamping rod 11 is pressed down. The turntable 7 can rotate only after the clamping rod 11 is completely separated from the clamping hole 1301.

[0053] After the turntable 7 rotates 180°, the locking rod 11 is coaxially arranged with the locking hole 1301 on the other side, and is inserted into the locking hole 1301 under the push of the second spring 12, thereby completing the automatic locking of the turntable 7. In this way, even if the operator forgets to insert the insertion rod 16, the piston 17 will not rotate during the processing, thereby improving the safety of the operation.

[0054] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
