Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
Referring to fig. 3-5, the present invention discloses a locating pin, which comprises a pin head 1 and a pin column 2.
The pin head 1 comprises a guide part 11 and a clamping part 12, the guide part 11 is arranged on the clamping part 12, the top of the guide part 11 is round-head-shaped, the round-head-shaped guide part can prevent products from being scratched, the yield of the products can be improved, the periphery of the guide part 11 is conical, and the guide part has a guide effect due to the adoption of a conical structure; the positioning portion 12 is a cylindrical structure, in this embodiment, the height of the positioning portion 12 is 1.8mm, the diameter of the positioning portion 12 is 1.98mm, the height of the guide portion 11 is 1.6mm, and the height of the pin head 1 is 3.4 mm.
The pin column 2 is of a cylindrical structure, the top end of the pin column 2 is provided with a limiting block 21, the limiting block 21 is arranged between the pin head 1 and the pin column 2, a clamping step 3 is formed between the bottom surface of the pin head 1 and the outer side surface of the limiting block 21, and the top surface of the limiting block 21 is contacted with the bottom surface of the clamping part 12;
the diameter of round pin post 2 is greater than the diameter of stopper 21, the diameter of round pin head 1 bottom (screens portion 12) is greater than the diameter of round pin post 2, form a recess 22 in the outside of stopper 21 between round pin head 1 and round pin post 2, form screens step 3 between the bottom surface of screens portion 12 and the lateral surface of stopper 21, formation of screens step 3 can spacing height for the locating pin can carry out highly spacing when installing in the locating hole, screens step 3 can block on the contact surface, and can conveniently be accurate spacing height again, thereby ensures that the height that the locating pin was installed in the locating hole is unanimous.
When the step structure with the large upper part and the small lower part is machined and formed, the step structure can not be machined in place at the position due to a lathe or a grinding machine, when the groove 22 is machined, the step structure is equivalent to over-cutting machining, so that when the positioning pin is arranged in the positioning hole, the forming surface of the clamping step 3 is more attached to the contact surface and is more smooth.
In this embodiment, the diameter of the pin 2 is 1.6mm, the height of the pin 2 (including the height of the limiting block 21) is 11.16mm, and the height of the whole positioning pin is 15 mm.
When the positioning pin is installed in the positioning hole, the bottom end of the pin column 2 is firstly inserted into the positioning hole, the size of the positioning hole is the same as the diameter of the pin column 2, when the pin column 2 is inserted into the bottom surface of the clamping part 12 of the pin head 1, because the diameter of the clamping part 12 is larger than that of the pin column 2, the clamping part 12 can be clamped outside the positioning hole, the clamping step 3 formed between the clamping part 12 and the outer side surface of the limiting block 21 can be attached to the surface of the die, and because of the formation of the groove 22, the forming surface of the clamping step 3 can be more attached to the surface of the die, and is smoother, and the precision is also improved. Can avoid because the locating pin is installed on the mould when too dark or too shallow, cause the production line to shift to the product, the product size is bad, and the product shape is cut or can be held by the locating pin when getting the product, can not get the product or form the abnormal conditions such as scraping the flower to the product.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
