Abstract

The utility model discloses a detachable top plane locating pin structure which comprises a base, a locating pin and a sleeve. Two adjusting holes are formed in the base, and the sleeve is arranged between the locating pin and the base. The detachable top plane locating pin structure overcomes the defects that in the prior art, due to the fact that the position of a locating pin of an upper die and the position of a locating pin of a lower die of a die are fixed, when material parts which are of a similar structure are machined, the die needs to be replaced, and waste of machining is caused. According to the improved detachable top plane locating pin structure, due to the fact that a compressed spring is arranged between the tail end of the locating pin and the base, the locating position of the locating pin can be changed, the range the of sizes of workpieces which can be applicable to die machining can be enlarged, the frequency of replacement of the die is reduced, and cost is reduced.

Description

A kind of detachable top plane positioning latch structure
Technical field
The utility model belongs to a kind of positioner, particularly a kind of detachable top plane positioning latch structure.
Background technology
In the plant equipment, alignment pin is a kind of part commonly used, normally be fixed on the mould at the alignment pin on the mould, the position cannot change, and matching used upper die and lower die can only be processed the materials and parts of single specification, when the similar materials and parts of processing structure, need more mold exchange, cause production efficiency low, and cause the waste of mould, improved production cost.
The utility model content
Technical problem to be solved in the utility model provides a kind of detachable top plane positioning latch structure, can enhance productivity, reduce production costs.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of detachable top plane positioning latch structure, comprise base, alignment pin, fixture, described base is provided with a locating slot, on the described locating slot fixture is installed, and is provided with cavity in the described fixture, described cavity is provided with pilot hole, described alignment pin is installed on the pilot hole of fixture, and described alignment pin front end stretches out pilot hole, is provided with stage clip between rear end and the base.
Further, the alignment pin end is provided with limited block, can cooperate the scope of stretching out of restriction alignment pin with pilot hole.
Further, offer tapped through hole on the described locating slot, described fixture has screw thread outward, is connected with locating slot by tapped through hole, and spiral connects, and is simple, convenient.
Further, the head of described alignment pin is circular arc, reduces the wearing and tearing to the processing materials and parts.
Add man-hour, the front end of the materials and parts pin that is positioned blocks, play positioning action, when machining, alignment pin is depressed, materials and parts can continue to move ahead, under the positioning action of other positioner, proceed processing, when processing different materials and parts, can be by changing the alignment pin of different length, to adapt to the materials and parts of processing worker different size if need.
The beneficial effect that the utlity model has: 1, alignment pin is scalable by spring, to adapt to the materials and parts of different processing dimensions.2, fixture is threaded with locating slot, makes that installation is more convenient, more stable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Shown in Fig. 1, the utility model is a kind of detachable top plane positioning latch structure, comprise base 1, alignment pin 2, fixture 3, described base is provided with a locating slot 4, on the described locating slot 4 fixture 3 is installed, and is provided with cavity in the described fixture 3, described cavity is provided with pilot hole 5, described alignment pin 2 is installed on the pilot hole 5 of fixture 3, and described alignment pin 2 described alignment pin front ends stretch out guiding 5 holes, are provided with stage clip 6 between rear end and the base 1.
Described alignment pin 2 ends are provided with limited block 7, can cooperate the scope of stretching out of restriction alignment pin 2 with pilot hole.
Offer tapped through hole on the described locating slot 4, outside the described fixed cover 3 screw thread is arranged, be connected with locating slot 1 by tapped through hole, passable like this connected mode makes things convenient for installation, the dismounting of fixed cover 3.
The head of described alignment pin 2 is circular arc, reduces the wearing and tearing to the processing materials and parts.
During installation, alignment pin 2 is installed in the fixed cover by pilot hole, directly rotates fixed cover 3 simultaneously, be fixed on the base.
Add man-hour, the front end of the materials and parts pin 2 that is positioned blocks, play positioning action, when machining, alignment pin 2 is depressed, materials and parts can continue to move ahead, under the positioning action of other positioner, proceed processing, if need when processing different materials and parts, can be by changing the alignment pin 2 of different length, to adapt to the materials and parts of processing worker different size.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
