Detailed description of the invention
In order to make those skilled in the art be more fully understood that technical scheme, further illustrate technical scheme below in conjunction with accompanying drawing and by detailed description of the invention.
The present embodiment provides a kind of perforating press, is used for processing automotive hub centre bore, as shown in Figure 1-2, comprising:
Chassis 1, described chassis 1 is provided with punching press oil cylinder 2 and the telescopic oil cylinder no less than two 9, described punching press oil cylinder 2 top is provided with drift 3 in order to process the centre bore of wheel hub, described punching press oil cylinder 2 is arranged above conveyer belt 5 and transfer plate 8, being additionally provided with belt wheel 4 on described telescopic oil cylinder 9, telescopic oil cylinder 9 is connected with belt wheel 4 by connecting plate 13；Described belt wheel 4 drives described conveyer belt 5 to rotate, and belt wheel 4 is connected with motor with motor shaft rotation.Described transfer plate 8 offers conveyer belt 5 can be made to stretch out first through hole 81 at transfer plate 8 top and drift 3 can be made to stretch out second through hole 82 at transfer plate 8 top；Described transfer plate 8 is further arranged below support 10, and described support 10 is arranged at described punching press oil cylinder 2 both sides；
Clout doffer, described clout doffer is arranged at above described drift 3, and described clout doffer is arranged on described telescopic oil cylinder 9 by fixing plate 7, and described clout doffer can move up and down with described telescopic oil cylinder 9.
In the present embodiment, telescopic oil cylinder 9 quantity is four, and chassis 1 is rectangular configuration, and telescopic oil cylinder 9 is separately positioned on four angles place on chassis 1, and described telescopic oil cylinder 9 is symmetricly set on described chassis 1.
In order to make drift 3 pass smoothly from the second through hole 82, the second through hole 82 diameter is more than described drift 3 diameter.
Fixing plate 7 is for fixing clout doffer and position will not be occurred to offset, for needing fixing connection between this fixing plate 7 with described telescopic oil cylinder 9.
In order to enable automotive hub to be positioned at accurate machining position, transfer plate 8 being additionally provided with position adjusting mechanism 11, the purpose arranging position adjusting mechanism 11 is to alleviate the burden manually adjusted.In the present embodiment, position adjusting mechanism includes work portion 111 and moving part 112, and described work portion 111 is arranged on described moving part 112 and can along described moving part 112 linear slide.Specifically, moving part 112 is slide rail, and lower end, described work portion 111 is provided with slide block and cooperates with described moving part 112.Being additionally provided with cylinder (not shown) bottom transfer plate 8, the cylinder rod of cylinder is connected with slide block, and then can move forward and backward by band movable slider.
Owing to conveyer belt transmission precision is low, automotive hub may be inaccurate in the position of transfer plate 8, in order to make position adjusting mechanism 11 adjust the position of automotive hub accurately, the present embodiment is provided with on driver plate 8 position sensor 12, as shown in Figure 4, position sensor 12 quantity is four, and is distributed in the both sides of driver plate 8, when position sensor 12 detects wheel hub, position adjusting mechanism 11 moves to adjust the particular location of wheel hub.
As it is shown on figure 3, clout doffer 6 includes feeding-passage in the present embodiment, being symmetrically arranged with mobilizable baffle plate 63 in described feeding-passage, be also associated with recovering mechanism 64 between described baffle plate 63 and described feeding-passage, recovering mechanism 64 is stage clip.Stage clip is due to the restoring force of self, it is possible to make baffle plate 3 recover downwards naturalness along with the decline of drift 3.Wherein the structure of baffle plate 63 should be identical with the internal structure of feeding-passage, and then ensure that clout will not be fallen on punching press oil cylinder 2 along the gap between baffle plate and feeding-passage.
Specifically, feeding-passage includes vertical feeding passage 61 and tilts feeding-passage 62, and described vertical feeding passage 61 connects with described inclination feeding-passage 62.After clout is flushed to vertical feeding passage 61 by drift 3, clout can enter in inclination feeding-passage 62 from vertical feeding passage 61 and the connectivity part tilting feeding-passage 62, clout is affected along tilting feeding-passage 62 landing, can tilt feeding-passage 62 and be connected with clout collecting vessel (not shown) by self gravitation.Wherein, vertical feeding passage 61 and the angle that tilts between feeding-passage 62 are less than 45 °, and this kind of setting is prevented from clout and gathers tilting to stop in feeding-passage 62, it is to avoid inclination feeding-passage 62 is blocked by clout.
Baffle plate 63 is positioned at described vertical feeding passage 61, and described baffle plate 63 is positioned at the lower section of described vertical feeding passage 61 and the connectivity part of described inclination feeding-passage 62.
In order to anti-baffle plate hangs downwards in its natural state, baffle plate 63 is further arranged below limited block 65, and described limited block 65 is positioned on the sidewall of described vertical feeding passage 61, and described limited block 65 is symmetrical arranged.Pass through gemel connection between baffle plate 63 and described vertical feeding passage 61 medial wall simultaneously.In other embodiments, baffle plate 63 can also pin joint with described vertical feeding passage 61.
This perforating press duty is as follows:
Automotive hub is delivered to above transfer plate 8 by conveyer belt 5, conveyer belt 5 stops, now position adjusting mechanism 11 and position sensor 12 position to automotive hub that cooperates is adjusted, adjust behind tram, punching press oil cylinder 2 moves together with telescopic oil cylinder 9, the clout doffer 6 arranged on telescopic oil cylinder holds out against above automotive hub, punching press oil cylinder 2 holds out against below automotive hub, owing to punching press oil cylinder 2 is primary-secondary oil cylinders, therefore drift 3 is connected with the seed oil cylinder rod of punching press oil cylinder 2, and drift 3 is upwards to automotive hub punching press.The clout that punching press falls enters after in clout doffer 6 and falls in clout collecting vessel from clout doffer 6 again.
Note, the ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not limited to the embodiments described above; described in above-mentioned embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements both fall within the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
