Problems solved by technology

[0006] The above-mentioned patent applications are all designed for the circular surface of the piston rod. However, the surface of the piston cooling nozzle of the present application is flat, so the above-mentioned patent application still cannot solve the problem of requiring two processes and multiple clamping, which increases the The transportation cost, labor cost and qualified rate are reduced. At the same time, only one workpiece to be processed can be clamped at a time, resulting in low production efficiency and high manufacturing cost.

Embodiment 1

[0036] The automatic unloading device includes an electromagnet sheet arranged on the top of each set rod. The area of ​​each electromagnet piece is smaller than the area of ​​the hole in the nozzle body. In this way, without affecting the automatic feeding, after the electromagnet is energized, it can automatically avoid the elastic positioning pin 6, and the corresponding processed piston cooling nozzle body is attracted and removed from the clamp body 3.

Embodiment 2

[0038]The automatic unloading device includes a groove 14 arranged on the bottom plate 1 and parallel to the clamp body 3 , and a second push rod is arranged in the groove 14 . A positioning rod whose height can be raised and lowered is arranged in the groove 14, and the positioning rod can cooperate with the positioning pin hole 11 of the piston cooling nozzle body hole. The positioning rod is preferably arranged at the bottom of the groove 14, and several corresponding through holes are arranged in the groove 14, and the positioning rod can pass through the through holes.

[0039] The above method of using the jig capable of automatically loading and unloading the piston cooling nozzle body hole processing includes the following steps:

[0040] The first step, sleeve loading: manually or automatically, the middle holes 9 of the nozzle bodies of several workpieces 8 to be processed are sequentially set on the set rods in each sleeve 13 .

[0041] In the second st...

Embodiment 1

[0050] The mechanical arm 12 moves in the direction of the clamp body 3, the electromagnet at the top of the sleeve rod is energized, and points to the finished piston cooling nozzle body, but deviates from the elastic positioning pin 6; the mechanical arm 12 continues to move forward until the electromagnet The processed piston cooling nozzle body is attracted; then, the mechanical arm 12 moves in reverse, the electromagnet is de-energized, and the piston cooling nozzle body is removed.

Abstract

The invention discloses a utilization method of a hole making fixture with functions of automatic mounting and demounting of piston cooling nozzles. The method includes the steps: enabling a sleeve to charge, enabling the fixture to wait for feeding, enabling an automatic feeding device to feed, clamping a to-be-processed workpiece, making a dowel hole, turning the fixture, making an oil pipe hole, enabling an automatic discharging device to discharge and the like. By adoption of the method, the plurality of to-be-processed piston cooling nozzles can be clamped in one time, and two procedures of marking the oil injection pipe hole and the dowel hole can be carried out at the same time. In addition, by the automatic feeding device for automatic feeding and the automatic charging device for automatic discharging, automatic mounting or automatic demounting of the to-be-processed workpieces can be realized, the technical problems of high labor intensity and low efficiency in manual feeding are avoided, automation of the whole machining process is realized completely, and operation efficiency is greatly improved.

Description

technical field [0001] The invention relates to an auxiliary processing method for a piston cooling nozzle body, in particular to a method for using a jig capable of automatically loading and unloading a hole processing fixture for a piston cooling nozzle body. Background technique [0002] The piston cooling nozzle is one of the important parts in the cooling system of the diesel engine. Its function is to accurately and timely spray the cooling oil into the predetermined bottom of the piston, fully cool the piston, and prevent the piston from expanding too much due to heat and seizing the cylinder. Cause serious quality accident of diesel engine. [0003] In order to accurately spray the cooling oil into the predetermined bottom of the piston, the piston cooling nozzle body needs to be provided with a positioning pin hole, an oil pipe hole and a hole in the nozzle body at the same time, and there are relative positional requirements between the three holes. When the pisto...
