Abstract
The invention relates to an insert type locating pin locating mechanism. A locating pin is arranged on one side of a tool base plate. A pin sleeve matched with the locating pin is arranged outside the locating pin. The pin sleeve is installed on the tool base plate. The lower end of the locating pin is provided with a first pin shaft which is arranged on a lever. One end of the lever is provided with a second pin shaft, and the other end of the lever is provided with a handle. The insert type locating pin locating mechanism has the advantages of being convenient to operate and free from interference and collision.
Description
Technical field
The present invention relates to the Machining Technology field, specifically a kind of for the mach plug-in type alignment pin of engine cylinder body detent mechanism.
Background technology
In the whole production process of cylinder block machined, be generally at first to process bottom surface and two pin-and-holes in the first order or the second order at present, later all process steps is all to locate with bottom surface and two pin-and-holes, namely plane and two pits locate mode commonly used.Cylinder block is such in the operation principle that adds this locate mode of employing in man-hour: the lifting cylinder block is placed on frock, the bottom surface is contacted with frock base plate locating surface, simultaneously two fixed locating studs on frock enter on the cylinder body bottom surface in two pin-and-holes, cylinder body has just been completed the location like this, then compress cylinder block, prepare to begin processing.Adopt this fixed alignment pin detent mechanism to have distinct issues to be exactly: because two alignment pins exceed frock base plate locating surface, and be fixed on the frock base plate, when the lifting cylinder body when dropping near tool positioning surface, because: a, cylinder body are heavier; B, cylinder body pin-and-hole and alignment pin are difficult to very just getting; C, cylinder body are difficult to hang to get unusual level, that is to say that pin-and-hole and locating surface are difficult to very vertical, are very easy to free interferences, collision when alignment pin enters dowel hole, and damage cylinder block or frock even both sustain damage.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art, a kind of easy to operate plug-in type alignment pin detent mechanism of interfering, colliding can avoided again is provided.
Technical scheme: in order to solve the problems of the technologies described above, a kind of plug-in type alignment pin detent mechanism of the present invention, be provided with alignment pin in frock base plate one side, be provided with in described alignment pin outside the guide that is mated, described guide is arranged on described frock base plate, is provided with the first bearing pin in described alignment pin lower end, and described the first bearing pin is located on lever, be provided with the second bearing pin at described lever one end, the other end is provided with handle.
Be provided with bolt on the frock base plate of described alignment pin one side.
Described the second bearing pin is located at the lower end of described bolt.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: overall structure of the present invention is simple, by first cylinder body being put on the frock base plate, and then the mode of inserting alignment pin realizes the location of cylinder body in machining process, avoided cylinder body to be difficult for accurately aligning with fixed alignment pin the damage that causes cylinder block or alignment pin because of the cylinder block pin-and-hole in clamping process, easy to operate, suitable promoting the use of.

Accompanying drawing 1 is structural representation of the present invention.
Wherein:
1, frock base plate; 2, alignment pin; 3, guide; 4, the first bearing pin; 5, lever; 6, the second bearing pin; 7, handle; 8, bolt
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of plug-in type alignment pin detent mechanism of the present invention, be provided with alignment pin 2 in frock base plate 1 one sides, be provided with in described alignment pin 2 outsides the guide 3 that is mated, described guide 3 is arranged on described frock base plate 1, is provided with the first bearing pin 4 in described alignment pin 2 lower ends, and described the first bearing pin 4 is located on lever 5, be provided with the second bearing pin 6 at described lever 5 one ends, the other end is provided with handle 7; Be provided with bolt 8 on the frock base plate 1 of described alignment pin 2 one sides; Described the second bearing pin 6 is located at the lower end of described bolt 8.overall structure of the present invention is simple, by first cylinder body being put on the frock base plate, and then the mode of inserting alignment pin realizes the location of cylinder body in machining process, avoided cylinder body to be difficult for accurately aligning with fixed alignment pin the damage that causes cylinder block or alignment pin because of the cylinder block pin-and-hole in clamping process, easy to operate a kind of thinking and the method for the invention provides, method and the approach of this technical scheme of specific implementation are a lot, the above is only the preferred embodiment of the present invention, should be understood that, for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each part all available prior art realized.
