By adopting at least three milling cutter assemblies 3 to synchronously process a corresponding number of exhaust grooves so as to improve the processing efficiency of the cylinder cover, and the inclined downward water curtain sprayed out by the flat opening on the hollow clamping jaw 6 falls on the cylinder cover, on one hand, scraps are pushed to the end milling cutter 4 along the air guide groove and cooled to the end milling cutter 4, and part of scraps near the end milling cutter 4 are transferred to the surface of the cylinder cover from the air guide groove under the action of rotation of the end milling cutter 4 and flushing of cooling water. On the other hand, flying scraps transferred to the surface of the cylinder cover move towards the exhaust holes along the surface of the cylinder cover under the flushing of the water curtain, and the water curtain sprayed by the flat nozzle on the adjacent hollow clamping jaw 6 forms a connected water curtain edge on the surface of the cylinder cover, so that the problem that the scraps are not flushed and remain on the cylinder cover after the air guide groove is processed is solved.
According to the invention, at least three air guide grooves communicated with the central exhaust hole of the cylinder cover are synchronously machined on the surface of the cylinder cover through the at least three milling cutter assemblies 3, so that the time for machining the air guide groove link of the cylinder cover is greatly shortened, in the process that the hollow clamping jaw 6 on the outer side of the milling cutter assemblies 3 moves along with the milling cutter assemblies 3 towards the chip removal hole 2, the contact part of the opposite milling cutter 4 and the cylinder cover is cooled by the water curtain sprayed by the flat nozzle 7 on the inner side of the hollow clamping jaw 6, the air guide groove and the scraps on the surface of the cylinder cover are flushed, the water curtain sprayed by the adjacent flat nozzle 7 forms a connected water curtain edge on the surface of the cylinder cover, and the scraps are prevented from being left on the cylinder cover due to being not flushed, so that the time for machining the air guide grooves and the scraps on the surface of the cylinder cover is not required to be cleaned, the time for machining the air guide groove link of the cylinder cover is further shortened, and the machining efficiency of the cylinder cover is remarkably improved.
In addition, the outer side of the milling cutter assembly 3 is provided with a rodless cylinder 8 for driving the hollow clamping jaw 6 to lift, and the hollow clamping jaw 6 descends to the outer side of the cylinder cover along with the rodless cylinder 8, so that the plurality of hollow clamping jaws 6 can synchronously move towards the chip removal holes 2 along with the plurality of milling cutter assemblies 3 to push the cylinder cover with the circular outer edge to a machining position aligned with the exhaust holes on the cylinder cover. When the hollow clamping jaw 6 rises to the upper part of the cylinder cover along with the rodless cylinder 8, the water curtain sprayed by the flat-mouth nozzle 7 can be used for flushing scraps to the exhaust hole in the center of the cylinder cover along with the movement of the hollow clamping jaw 6 to the scrap discharging hole 2.
Because the hollow clamping jaw 6 moves together with the milling cutter assemblies 3 which synchronously move, the cylinder cover can be positioned at the centers of the milling cutter assemblies 3 and the hollow clamping jaw 6 after being clamped by the plurality of hollow clamping jaws 6, and the end milling cutter 4 and the cylinder cover are consistent in initial position, so that the processing precision of the air guide groove is improved and maintained.

The end mill 4 can pass through between the adjacent positioning claws 12 and form an air guide groove communicated with the exhaust hole, and the guide post 11 is always positioned above the exhaust hole by the support of the positioning claws 12.
In addition, the top of bracket 501 is provided with annular surrounding edge 14, and the top of annular surrounding edge 14 is provided with top cap 15, and annular surrounding edge 14 and top cap 15 and bracket 501 form the protective housing to avoid the potential safety hazard that the milling cutter assembly 3 of its inside exposes and exists and the easy dirty problem. The top cover 15 is rotatably provided with a polygonal inner hole barrel 16 through a bearing, polygonal holes are formed in the polygonal inner hole barrel 16, polygonal columns 17 are inserted in the polygonal inner hole barrel in a sliding mode, and the pressurizing cylinder 13 is arranged at the top of the cylinder cover and connected with the polygonal columns 17.
And, the top of the cylinder cover is provided with an intermittent rotating mechanism 18 connected with the polygonal inner hole cylinder 16, so that the cylinder cover pressed by the positioning claws 12 can rotate by a corresponding angle for processing the next group of air guide grooves after processing one group of air guide grooves, and the requirement of processing a plurality of air guide grooves on the cylinder cover is met.
The intermittent rotating mechanism 18 comprises a rotating driving motor 1801 and a gear set 1802 which are arranged on the top cover 15, an outer gear ring 19 is sleeved on the polygonal inner hole barrel 16, and the rotating driving motor 1801 is in transmission connection with the outer gear ring 19 by means of the gear set 1802.
The supporting mechanism 9 comprises a plurality of supporting cylinders which are circumferentially distributed at equal intervals around the chip removal holes 2, an opening through which the cylinder cover passes is formed between every two adjacent supporting cylinders, and the supporting mechanism 9 can control the descending speed and formation of the driving bracket 501 to adapt to the requirement of the milling cutter assembly 3 on air guide groove processing of the cylinder cover while supporting the bracket 501, so that the structure of the milling cutter assembly 3 is simplified.
And based on the above optimization of the supporting mechanism 9, the structure of the milling cutter assembly 3 can be simplified, which is beneficial to reducing the cost of arranging a plurality of milling cutter assemblies 3, and more importantly, is beneficial to solving the problem that the end mill 4 cannot move to the exhaust hole due to the interference of the plurality of milling cutter assemblies 3 when the plurality of milling cutter assemblies 3 are mutually close, namely, the air guide groove communicated with the exhaust hole cannot be processed due to the fact that the structure of the end mill 4 is bulky.
Wherein, milling cutter assembly 3 includes eccentric casing 301, high-speed motor 302, blade holder 303 and drive assembly 304, high-speed motor 302 sets up in eccentric casing 301, eccentric casing 301's bottom is provided with the narrow head that extends to chip removal hole 2 direction, blade holder 303 rotates the one end that sets up at the narrow head to do benefit to and avoid end milling cutter 4 to take place the condition of contradicting each other before entering exhaust hole milling cutter assembly 3, drive assembly 304 sets up in the narrow head and is connected blade holder 303 and high-speed motor 302 transmission, eccentric casing 301's outside is provided with the spacing spout 20 that supplies hollow clamping jaw 6 vertical slip grafting.

Since the water curtain edge is located behind the water curtain edge in the traveling direction when the water curtain edge is transferred to the cylinder head and cannot be flushed to the exhaust hole if the water curtain edge is located at the contact position of the end mill 4 and the cylinder head, the cooling effect of the end mill 4 is poor and it is difficult to transfer the flying chips accumulated in the air guide groove to the surface of the cylinder head, in order to solve the contradiction, the following optimization is also performed on the flat nozzle 7:
the flat nozzle 7 comprises a main nozzle 701 and two auxiliary nozzles 702 which are respectively arranged at two sides of the main nozzle 701, wherein the main nozzle 701 and the auxiliary nozzles 702 are obliquely downwards arranged, the inclination degree of the main nozzle 701 is smaller than that of the auxiliary nozzles 702, namely, the water flow sprayed by the main nozzle 701 is positioned in front of the water flow sprayed by the auxiliary nozzles 702 at two sides, the water flow sprayed by the main nozzle 701 cools the contact part of the opposite milling cutter 4 and the cylinder cover, part of scraps are flushed out of the air guide groove, and the water flow sprayed by the auxiliary nozzles 702 forms a water curtain edge behind the scraps flushed out of the air guide groove, so that the contradiction is solved.
In addition, along with the synchronous exhaust hole that removes to the cylinder cap center of adjacent hollow clamping jaw 6, the interval of adjacent hollow clamping jaw 6 can reduce, at this moment, if not adjust the water curtain width, can lead to the waste of water resource because the water curtain is too wide. In addition, although two water curtains ejected from adjacent sub-nozzles 702 can form mutually connected water curtain edges on the cylinder head, since the length of the boundary line of the adjacent water curtains gradually increases and the end point of the boundary line gradually moves upwards, the water flow at the end point of the boundary line has larger kinetic energy due to the fact that the water flow is closer to the sub-nozzles, so that the collision of the adjacent water curtains at the end point of the boundary line is more intense, the water flow at the end point of the boundary line on the cylinder head is more turbulent, and part of scraps are likely to be flushed to the rear of the water curtain along with the turbulent water flow at the end point of the boundary line, and therefore, the width of the water curtain ejected from the sub-nozzles 702 needs to be adjusted in the process that the hollow clamping jaw 6 moves towards the exhaust hole.
