Abstract
The utility model relates to a quick locating pin which comprises a pin head, a first pin pillar and a second pin pillar, wherein the pin head, the first pin pillar and the second pin pillar are connected in series, the length of the second pin pillar is longer than that of the first pin pillar, the diameter of the second pin pillar is smaller than that of the first pin pillar, the pin head is a frustum in shape, and the top of the pin head is a arc-shaped surface. The quick locating pin is simple in structure, a die can be quickly positioned on processing platform, a reject rate of productions is reduced, workload of on-spot inspectors is reduced, and labor efficiency is improved.
Description
Technical field
The utility model relates to the quick location technique field, is specifically related to a kind of quick locating stud.
Background technique
Locating stud is a kind of localization criteria spare of automobile and machinery industry extensive use, and the locating stud of at present automobile industry use mainly is selected from " the die used in automobile standard " of China Automobile Industry Corporation's establishment, i.e. QM3201-93 and QM3202-93.
This standard setting pin is to utilize straight pin to cooperate with the location and installation hole to realize fixed installation.Because locating stud adopts drive fit with cooperating of location and installation hole, the means of fixation of this cooperation is for the mounting hole of non through hole, easily form the sealed gas chamber of inner space, make the air quality of its inner space can not change or change less, volume of air then has greatly changed, thereby air pressure changes and causes be difficult for installing accurately when causing locating, especially when the bed platform of lathe is located with mould, inconvenience is installed, and location efficiency is low.
Summary of the invention
The purpose of this utility model is in order to overcome defects, to provide a kind of energy quick jig, the quick locating stud of increasing work efficiency.
To achieve these goals, the quick locating stud of the utility model design, this locating stud comprises plunger, the first pin and the second pin that connects successively, the length of described the second pin is greater than the length of the first pin, the diameter of described the second pin is less than the diameter of the first pin, described plunger is taper type, and the top of described plunger is arc shaped surface.
In technique scheme, be 45 ° of angles between two sides on the longitudinal section of described plunger.
In technique scheme, be provided with radial direction through hole in the first pin.
The utility model arranges two pins, and the external diameter of two pins and sample different in size when being used for bed platform and mould location, can play the effect of quick jig effectively, have improved working efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, plunger; 2, the first pin; 3, the second pin; 21, through hole.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Quick locating stud as shown in Figure 1, this locating stud comprises plunger 1, the first pin 2 and the second pin 3 that connects successively, the length of the second pin 3 is greater than the length of the first pin 2, the length of common the second pin 3 is about 70mm, the length of the first pin 2 is about 25mm, the diameter of the second pin 3 is less than the diameter of the first pin 2, and plunger 1 is taper type, and the top of plunger 1 is arc shaped surface.On the longitudinal section of plunger 1 between two sides angle R be 45 °, guaranteed the accuracy of locating face.Being provided with diameter in the first pin 2 is the radial direction through hole 21 of 8mm, makes things convenient for positioning action.
The utility model is simple in structure, mould can be positioned effectively rapidly reduced the product disqualification rate on the platform, has reduced field test person's workload, has improved efficiency.
The content that is not described in detail in this specification belongs to the known prior art of related domain professional and technical personnel.
