Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a cross-sectional view of the present structure;
fig. 2 is an enlarged view at a of fig. 1.
Detailed Description
Referring to fig. 1 and 2, the invention discloses a large cap straight ejector rod straight ejector seat structure, which comprises a large cap 1, a template assembly, an ejector plate 2 and a bottom plate 3, wherein the ejector plate 2 is provided with an upper block and a lower block, an ejector rod hole and a straight ejector rod 4 sliding with the ejector rod hole are arranged in the template assembly, the template assembly comprises an upper template 5 and a lower template 5, a seat hole communicated with the ejector rod hole is arranged in the template assembly, a straight ejector seat 5 is arranged in the seat hole, the seat hole comprises a first hole and a second hole, the diameter of the first hole is larger than that of the second hole, the intersection position of the first hole and the second hole forms a hole step surface, the straight ejector seat 5 comprises a first ejector seat part 51 and a second ejector seat part 52, the diameter of the first ejector seat part 51 is larger than that of the second ejector seat part 52, the intersection position of the first ejector seat part 51 and the second ejector seat part 52 forms a seat step surface, gaps are respectively arranged between the first ejector seat part 51 and the inner wall of the first hole and the inner wall of the second ejector seat part 52, the length of the second top seat part 52 is larger than that of the second hole, a counter bore is arranged in the straight top seat 5, a screw 6 is fixedly connected with the straight ejector rod 4 into a whole through the counter bore, an elastic gasket is arranged in the counter bore to prevent the screw 6 from loosening, and through the structure, the screw 6 is not directly connected with the straight ejector rod 4 and is fixedly connected with the straight ejector rod 4 through the straight top seat 5; the straight top seat 5 and the inner wall of the seat hole are provided with a gap, and the length of the second top seat part 52 is larger than that of the second hole, so that the straight top seat 5 can be fixedly connected with the straight top rod 4 without fixing the straight top seat 5 and the ejector plate 2, and a gap can be formed between the seat step surface and the hole step surface, the structure ensures that the straight top seat 5 has certain degree of freedom in the radial direction, is fixed with the straight top rod 4 into a whole in the axial direction, and has certain movable gap space with the ejector plate 2, when the guide sleeve 7 has radial deflection, the straight top rod 4 can deflect along with the guide sleeve 7, and the straight top seat 5 can deflect along with the straight top rod 4 through the gap and can ensure the ejection and retraction of the straight top rod 4.
As shown in the figure, an adjusting plate 8 for adjusting the length of the ejector rod hole is arranged at the hole bottom of the ejector rod hole, the adjusting plate 8 is fixed at the hole bottom of the ejector rod hole through a screw 6, because the straight ejector rod 4 is longer, the ejector rod hole is also very long, so that the length error between the straight ejector rod 4 and the ejector rod hole is larger, if the straight ejector rod 4 is short, the adjusting plate 8 with a thicker thickness needs to be installed, so that the large cap 1 can be completely ejected when the straight ejector rod 4 is pushed out by the ejector plate 2, and the stroke of the ejector plate 2 is fixed; on the contrary, if the straight ejector rod 4 is too long, a thinner adjusting plate 8 can be installed. The adjusting plate 8 is provided with an adjusting hole which is communicated with the second hole, the second footstock part 52 is positioned in the adjusting hole and the second hole, a gap is arranged between the second footstock part 52 and the inner wall of the adjusting hole, the length of the second footstock part 52 is greater than the sum of the lengths of the second hole and the adjusting hole, and therefore the straight footstock 5 cannot be directly locked with the ejector plate 2.
The principle is briefly described as follows: when the ejector plate 2 is pushed out, the adjusting plate 8 can push against the end surface of the straight ejector rod 4 so as to push out the straight ejector rod 4, and a gap is formed between the seat step surface and the hole step surface; when the ejector plate 2 returns to reset, the hole step surface extrudes the seat step surface, the straight ejector rod 4 is driven to return through the straight ejector seat 5, and at the moment, a gap is formed between the adjusting plate 8 and the end face of the straight ejector rod 4.
The structure of the straight ejector rod 4 and the straight ejector seat 5 of the large cap 1 provided by the embodiment of the invention is described in detail, a specific example is applied in the text to explain the principle and the implementation mode of the invention, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
