Embodiment 1

[0031] Embodiment one, see figure 1 , a piston boring machine, including a frame 7 and a cooling mechanism 75. The frame 7 is provided with two laterally distributed tool seats 71 and a workpiece fixing mechanism 72 between the two tool seats. The tool holder 71 is connected to the frame 7 in a laterally movable manner through a screw rod 73 extending laterally and cooperating with a threaded sleeve. A boring tool 74 is connected to the tool seat 71 . The boring bit 74 extends toward the workpiece securing mechanism. The boring tools on the two tool holders are coaxial. The workpiece fixing mechanism 72 includes a workpiece supporting seat 721 and a pressing cylinder 722 located above the tool supporting seat. The cooling mechanism 75 is used to cool the boring tool.

[0032] During use, the piston is rested on the workpiece support seat 721, and then the piston is pressed by the pressing cylinder 722. Both sides of the piston are then bored simultaneously from both side...

Embodiment 2

[0033] Embodiment two, the difference with embodiment one is:

[0034] see figure 2 , Frame 7 is provided with shock-isolation seat 9. The vibration isolation seat 9 includes a vertical damping oil cylinder 91 and a shock absorbing spring 92 sleeved on the damping oil cylinder. The damping oil cylinder 91 includes a damping oil cylinder body 911 . The damping cylinder block 911 is connected with the frame 7. A first piston 912 is disposed inside the damping oil cylinder body 911 . The first piston 912 is connected to the supporting seat 93 through the piston rod 913 . One end of the damping spring 92 is affixed together with the piston rod 913, and the other end is affixed together with the cylinder body 911 of the damping oil cylinder.

[0035] see image 3 , The second piston 914 and the separation plate 94 are also provided in the damping cylinder body 911 . The separating plate 94 and the damping oil cylinder body 911 are affixed together. A first oil chamber 915 ...

Embodiment 3

[0042] Embodiment three, the difference with embodiment two is:

[0043] see Figure 6 , The frame 7 is also provided with an illuminating lamp 77 . The illuminating lamp 77 is connected on the frame 7 through the lamp clip 10 . The lamp clip 10 includes a base 1 and a lamp cap fixing part 2 . Base 1 is connected with frame 7 together. The illuminating lamp 77 is connected on the lamp cap holder 2 .

[0044] see Figure 7 , One side of the base 1 is provided with a base fixing clip 3 . The base fixing clip 3 is integrated with the base 1 . The base fixing clip 3 includes a first clip 31 and a second clip 32 . The first clamping piece 31 is provided with a threaded hole 33 of the clamping piece. The threaded hole 33 of the clip part is a through hole. The threaded hole 33 of the clip part is threadedly connected with a fastening bolt 34 of the clip part. An elastic holding piece 4 is disposed between the first clamping piece 31 and the second clamping piece 32 . The ...

Abstract

The invention relates to machine tools, and provides a piston boring machine. The piston boring machine is characterized in that the piston boring machine comprises a machine frame; two tool aprons and a workpiece fixing mechanism are arranged on the machine frame, the two tool aprons are distributed transversely and can move transversely, and the workpiece fixing mechanism is located between the two tool aprons; boring tools which face the workpiece fixing mechanism are connected to the tool aprons, and the boring tools on the two tool aprons are coaxial; and the workpiece fixing mechanism comprises a workpiece fixing base and a pressing cylinder located on the workpiece supporting base. The piston boring machine can be used for boring the two sides of a piston at the same time, and the problems that when the piston is bored in twice, the production efficiency is low, and the coaxiality of holes in the two sides is poor are solved.

Description

technical field [0001] The invention relates to machine tools, in particular to a piston boring machine. Background technique [0002] During the production process of the piston, coaxial holes need to be bored on both sides of the piston. The existing equipment can only bore out the holes on one side of the piston at one time, so when boring the holes on both sides, the holes on one side must be drilled and then the The piston is reversed and the hole on the other side is bored out. Due to the insertion error when the piston is fixed on both sides, the coaxiality of the holes on both sides is poor and the efficiency is low. Contents of the invention [0003] The invention provides a piston boring machine capable of boring both sides of the piston at the same time, which solves the problems of low production efficiency and low coaxiality of the holes on both sides caused by boring the piston twice . [0004] The above technical problems are solved by the following techni...
