Referring to figs. 1 to shown in Fig. 3, detent mechanism of the present utility model, including drive mechanism 1, the first alignment pin 2, second
Alignment pin 3, fixed block 6 and locating piece 5.Preferably, drive mechanism 1 can select cylinder.Drive mechanism 1, which is provided with, to be stretched with respect to it
The external part 11 for going out and retracting, external part 11 connects the first alignment pin 2 and the second alignment pin 3 by connecting plate 4, in drive mechanism
Drive under, 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,
Locating piece 5 is arranged on the upper end of fixed block, and workpiece 10 to be processed is placed on locating piece 5.It is provided with fixed block 6 and is available for connecting
The mobile space of plate 4, the first alignment pin 2 and the movement of the second alignment pin 3, to prevent from doing in the first alignment pin 2 and the second alignment pin 3
During stretching motion, interference problem is produced between connecting plate 4 and fixed block 6.First alignment pin 2 and the second alignment pin 3 and locating piece 5
Be slidably connected, and may pass through locating piece 5 to its outside stretch out or to its inside retract.So, enter when to workpiece 10 to be processed
Before row processing, 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
Positioning action is played to the workpiece 10 to be processed on locating piece 5.When needing to 10 blanking of workpiece, in the band of drive mechanism 1
Under dynamic, the first alignment pin 2 and the second alignment pin 3 are slidably retractable relative to locating piece 5, to avoid needing in blanking operation to the
The loss that one alignment pin 2 and the second alignment pin 3 are processed and brought.
Preferably, the first alignment pin 2 and the second alignment pin 3 and locating piece 5 are sliding fit together, 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 figure 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, it can make it that the stretching of the first alignment pin 2 and the second alignment pin 3 or retraction movement are more stable.
With reference to shown in figure 1, the bottom of fixed block 6 sets limited block 7, and the opening position corresponding with mobile space of limited block 7 is set
Fluted 71 and avoid passage 72.Connecting plate 4, the first alignment pin 2 and the second alignment pin 3 can move 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 move down, the first alignment pin 2 and the second alignment pin 3 are located at connecting plate
The position of 4 bottoms, which can avoid, 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

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 moves down in groove 71, when the bottom surface of connecting plate 4 and the bottom surface of groove
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 figure 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 determines.Again in the bottom of limited block 7, limited block 7 and fixed block 6 are fixed 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 figure 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 fix.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 figure 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 in the opening position positioned at the both sides of external part 11
Second alignment pin 3 is clamped in each self-corresponding neck 41, and clamping installation not only reduces the part required for installation, Er Qiean
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 caused by the reasons such as the error of drive mechanism 1 and the second alignment pin 3 are fluctuating, there is stuck phenomenon
Generation.
