Referring to figs. 1 to shown in Fig. 3, detent mechanism of the invention, including drive mechanism 1, the first alignment pin 2, second are positioned
Pin 3, fixed block 6 and locating piece 5.Preferably, drive mechanism 1 can select cylinder.Drive mechanism 1 provided with can its relative stretching with
The external part 11 of retraction, external part 11 connects the first alignment pin 2 and the second alignment pin 3 by connecting plate 4, in the band of drive mechanism
Under dynamic, the first alignment pin 2 and the second alignment pin 3 can do stretching motion.Drive mechanism 1 is arranged on the lower end of fixed block 6, positioning
Block 5 is arranged on the upper end of fixed block, and workpiece 10 to be processed is placed on locating piece 5.In fixed block 6 provided be available for connecting plate 4,
First alignment pin 2 and the mobile space of the second alignment pin 3 movement, to prevent from doing flexible in the first alignment pin 2 and the second alignment pin 3
During motion, interference problem is produced between connecting plate 4 and fixed block 6.First alignment pin 2 and the second alignment pin 3 are slided with locating piece 5
Connection, and may pass through locating piece 5 to its outside stretch out or retracted to inside it.So, added when to workpiece 10 to be processed
Before work, under the drive of drive mechanism 1, the first alignment pin 2 and the second alignment pin 3 are slided relative to locating piece 5 and stretched out, and to fixed
Workpiece 10 to be processed on the block 5 of position plays positioning action.When needing to 10 blanking of workpiece, under the drive of drive mechanism 1,
First alignment pin 2 and the second alignment pin 3 are slidably retractable relative to locating piece 5, fixed to first to avoid needing in blanking operation
The loss that the position alignment pin 3 of pin 2 and second is processed and brought.
Preferably, the first alignment pin 2 and the second alignment pin 3 and locating piece 5 are sliding fit together, it is to avoid the first positioning
The rocking in slip of alignment pin 3 of pin 2 and second, to ensure positioning precision.
With reference to shown in Fig. 1, mobile space is arranged on the bottom of the fixed block 6, the first alignment pin 2 and the second alignment pin 3
It is slidably connected with the top of fixed block 6, the top of fixed block 6 is played to the stretching motion of the first alignment pin 2 and the second alignment pin 3
Guide effect, can cause the first alignment pin 2 and the stretching of the second alignment pin 3 or retraction movement more to stablize.
With reference to shown in Fig. 1, the bottom of fixed block 6 sets limited block 7, and limited block 7 is set at position corresponding with mobile space
Fluted 71 and avoid passage 72.Connecting plate 4, the first alignment pin 2 and the second alignment pin 3 can be moved in groove 71.Avoid
Passage 72 is arranged on the bottom of groove 71, and the width for avoiding passage 72 is less than the width of groove 71, and is connected with groove 71.When
When connecting plate 4, the first alignment pin 2 and the second alignment pin 3 are moved down, the first alignment pin 2 and the second alignment pin 3 are located at connecting plate
The position of 4 bottoms, which can be avoided, to be avoided in passage 72, to avoid influenceing the removable of the first alignment pin 2 and the second alignment pin 3
Distance.Further, the bottom surface of connecting plate 4 and the bottom surface of groove 711 can release formula and offset, the top surface and fixed block of connecting plate 4
On can release formula towards the plane 61 of groove 71 and offset.That is, when the first alignment pin 2 and the second alignment pin 3 do stretching motion, even
Fishplate bar 4 is moved up in groove 71, when being offseted on the top surface and fixed block of connecting plate 4 towards the plane 61 of groove 71, and
The stretching campaign of one alignment pin 2 and the second alignment pin 3 is locked, and reaches farthest extended position.When the first alignment pin 2 and
When two alignment pins 3 do retraction movement, connecting plate 4 is moved down in groove 71, when the bottom surface and the bottom surface of groove of connecting plate 4
711 when being offseted, and the retraction movement of the first alignment pin 2 and the second alignment pin 3 is locked, and reaches farthest retracted position.
With reference to shown in Fig. 1, the top of limited block 7 is connected by positioning element 8 with fixed block 6, first by limited block 7 with fixing
Position between block 6 is determined.Again in the bottom of limited block 7, limited block 7 is fixed with fixed block 6 by secure component 9.Herein
Positioning element can be pin, secure component can be bolt, it is not limited to this.
Preferably, with reference to shown in Fig. 2, positioning element 8 is set close to the edges and corners on the top of limited block 7, and secure component 9 is close
The edges and corners of the bottom of limited block 7 are set, it is thus possible to complete positioning in the edges and corners of limited block 7 and fixed.Preferably, set
Two positioning elements 8 in edges and corners, both installation directions are oppositely arranged, reduced between limited block 7 and fixed block 6
Relative play so that positioning it is more accurate.Similarly, two fixed components 9 of edges and corners are arranged on, both installation directions are
It is oppositely arranged so that fixation is more firm.
With reference to shown in Fig. 3, connecting plate 4 is fixed on external part 11 by secure component 12, and the first alignment pin 2 and second is fixed
Position pin 3 is fixed on connecting plate 4.Bolt can be used herein, and connecting plate 4 is fixed on external part 11, it is not limited to
Bolt.
Preferably, connecting plate 4 is provided with two necks 41, the He of the first alignment pin 2 at the position positioned at the both sides of external part 11
Second alignment pin 3 is clamped in each self-corresponding neck 41, and the part not only reduced required for installing, Er Qiean are installed in clamping
Fill solid and reliable.
Preferably, gap coordinates between the first alignment pin 2 and the second alignment pin 3 and each self-corresponding neck 41, to prevent
When the first alignment pin 2 and the second alignment pin 3 caused by the reasons such as the error of drive mechanism 1 are fluctuating, there is stuck phenomenon
Generation.
Although some specific embodiments of the present invention are described in detail by example, the skill of this area
Art personnel are it should be understood that example above is merely to illustrate, the scope being not intended to be limiting of the invention.The skill of this area
Art personnel to above example it should be understood that can modify without departing from the scope and spirit of the present invention.This hair
