Description
Technical Field
The utility model relates to a positioning die frock field, concretely relates to can adopt quick locating pin of dismantling of multiple mode.
Background
At present, a complex composite material forming die usually comprises a plurality of sliding blocks, the combination of the sliding blocks and a main body die can be combined without step difference only through accurate positioning, and positioning pins are usually used in the die to ensure the position accuracy of the die during assembly.
The positioning pin used by the existing composite material forming die is generally a conventional cylindrical pin or a taper pin with threads, the cylindrical pin is fixed in a pin hole by interference and used for positioning a sliding block in the die, the positioning accuracy can be influenced by repeated dismounting, the taper pin has certain taper, the self-locking performance is good, the installation is convenient, and the influence of the repeated dismounting on the positioning accuracy is small. No matter be cylindric lock or taper pin, dismantle and all extract through the pin puller, dismantle loaded down with trivial details difficulty to the internal thread of pin very fragile when using the number of times more, need take out the pin again if damage after tapping, seriously influence work efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a dowel pin that can adopt multiple mode to dismantle, can improve the dismantlement efficiency of locating pin, not only can use the pin puller to dismantle the locating pin, can also use the stick-up to prize out the locating pin.
In order to solve the technical problem, the utility model discloses a technical scheme be: there is provided a dowel pin that is detachable in various ways, including: a cylindrical fixed rod body; the front end of the fixing rod body is provided with a pin head, the diameter of the pin head is larger than that of the fixing rod body, and the top of the pin head is provided with an internal threaded hole; a section of connecting neck is arranged between the fixing rod body and the pin head, the diameter of the connecting neck is larger than that of the fixing rod body, and the diameter of the connecting neck is smaller than that of the pin head; the tail end of the fixed rod body extends to form a guide section, and the guide section comprises a guide surface with a certain inclination.
In a preferred embodiment of the present invention, the length of the connecting neck ranges from 3 to 8 mm.
In a preferred embodiment of the present invention, the pin head is shaped like a mushroom head with a circular arc-shaped top.
In a preferred embodiment of the present invention, the length of the fixing rod is an effective fixing length.
In a preferred embodiment of the present invention, the guide section is conical.
In a preferred embodiment of the present invention, the positioning pin is used for positioning the composite material molding die.
The utility model has the advantages that: the utility model discloses can adopt the dowel of multiple mode dismantlement, novel structure satisfies location and the fixed function that should have, provides multiple dismantlement mode, easy operation, and the pin pulling success rate is high, can use general pin puller to extract the dowel, can also use simpler laborsaving efficient prize out the mode and demolish the dowel.
Drawings
FIG. 1 is a schematic structural view of a preferred embodiment of a dowel of the present invention that can be disassembled in a variety of ways;
FIG. 2 is a schematic top view of a locating pin shown being removable in a variety of ways;
the parts in the drawings are numbered as follows: 1-fixing rod body, 2-pin head, 3-connecting neck, 4-guiding section and 5-internal threaded hole.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1 and 2, an embodiment of the present invention includes:
a locating pin capable of being detached in multiple ways, preferably for locating a composite material forming die, comprises: the fixed body of rod 1, round pin nail head 2, connecting neck 3 and direction section 4.
The fixing rod body 1 is cylindrical, and the length of the fixing rod body 1 is the effective fixed length of the positioning pin, so that the length of the fixing rod body 1 is determined according to the size requirement of a die to be positioned.
The pin head 2 is positioned at the front end of the fixed rod body 1, the diameter of the pin head 2 is larger than that of the fixed rod body 1, an internal threaded hole 5 is formed in the top of the pin head 2, and the locating pin can be detached by using a pin puller due to the structure of the internal threaded hole 5. Preferably, the pin head 2 is in the shape of a mushroom head with an arc-shaped top, and the shape of the mushroom head can prevent scratches, is particularly suitable for fixing a composite material forming die during bag making, and can avoid damaging a vacuum bag paved on the surface of the die.
A section of connecting neck 3 is arranged between the fixing rod body 1 and the pin head 2, the diameter of the connecting neck 3 is larger than that of the fixing rod body 1, and the diameter of the connecting neck 3 is smaller than that of the pin head 2. The length of the connecting neck 3 is in the range of 3-8mm, preferably 5 mm. The 3 structures of the connecting neck enable the positioning pin to form a warping groove with a certain width in positioning, and the warping groove structure enables a prying bar or a copper plate to be conveniently used for prying out the positioning pin.
The tail end of the fixed rod body 1 extends to form a guide section 4, and the guide section 4 comprises a guide surface with a certain inclination. In this embodiment, the guide section 4 is conical.
The utility model discloses can adopt the dowel of multiple mode dismantlement, novel structure satisfies location and the fixed function that should have, provides multiple dismantlement mode, easy operation, and the pin pulling success rate is high, can use general pin puller to extract the dowel, can also use simpler laborsaving efficient prize out the mode and demolish the dowel.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship that the products of the present invention are usually placed when used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element to which the term refers must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
