As preferably, described pressing plate is provided with skewed slot, is provided with the spacer pin that is fixedly connected with the pressing plate guide holder in the described skewed slot.Offer skewed slot at pressing plate, in skewed slot, penetrate spacer pin in order to limit scope of activities and the position of pressing plate when moving up and down, when presser motion moves upward, make pressure head can be withdrawn into alignment pin inside, when pressing plate moves downward, make pressure head stretch out side open groove and cooperate with positioning table workpiece is compressed.
As preferably, described transmission mechanism comprises an end and the handle that supporting seat is flexibly connected, the other end can spin upside down, and the pull bar that is flexibly connected with the pressing plate lower end, the connecting rod that is provided with between the middle part of described handle and the pull bar lower end.Handle can drive the pull bar motion by connecting rod around rotating up and down with the junction of supporting seat, thus so that the motion that pressing plate can compress and get loose.
As preferably, described supporting seat is provided with the guide plate that pull bar is play the guiding role.Pull bar is by the effect of guide plate, and pull bar is in vertical direction motion all the time, avoids pull bar horizontal jitter to occur.
As preferably, described alignment pin is connected with pressing plate guide holder bolt.Alignment pin can be removed from the pressing plate guide holder, after using a period of time the alignment pin wearing and tearing more, the operation of changing alignment pin is comparatively convenient, can adopt different alignment pins for the location of different workpieces in addition, has improved versatility.
As preferably, be provided with cover plate outside the chute of described pressing plate guide holder, described cover plate medial surface is provided with the holddown groove that matches with spacer pin, and described cover plate is connected with pressing plate guide holder bolt.Cover plate covers at the chute opening simultaneously to be located, and makes outside pressing plate can not be exposed to, to playing a protective role by pressing plate.
As preferably, be provided with the adjusting pad between described alignment pin and the pressing plate guide holder.For the different workpiece of thickness, can adopt the adjusting pad of different-thickness, regulate the distance between pressure head and the positioning table, therefore can adapt to the workpiece of different wall, improved versatility.
Therefore, the utlity model has following beneficial effect: workpiece narrow to the weld pass or the closed cavity structure can carry out firm location and clamping, clamps simultaneously and locates and can realize at same device, has simplified anchor clamps, has saved the space.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is a kind of profile of the present utility model.
Among the figure, alignment pin 1, pressing plate 2, supporting seat 3, pressing plate guide holder 4, pull bar 5, handle 6, connecting rod 7, guide plate 8, cover plate 9, spacer pin 10, positioning table 11.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment as shown in Figure 1 and Figure 2, a kind of clamped-in style alignment pin is provided with a pressing plate guide holder 4 at supporting seat 3 tops, and pressing plate guide holder 4 positions its bottom surface by the step on the supporting seat 3, is fixed with supporting seat 3 by bolt to be connected.The chute that pressing plate guide holder 4 lateral surfaces are provided with, the chute outside of pressing plate guide holder 4 is provided with cover plate 9, and pressing plate guide holder 4 tops have been bolted alignment pin 1.The inside of alignment pin 1 is provided with the side open groove that communicates with chute, pressing plate 2 can slide up and down in chute and side open groove, pressing plate 2 top bendings form pressure head, pressure head can stretch out from the side open groove of alignment pin 1, alignment pin 1 bottom is provided with positioning table 11, and the cooperation by pressure head 2 and positioning table 11 comes clamping work pieces, and pressing plate 2 is provided with skewed slot, be provided with spacer pin 10 in the skewed slot, be respectively equipped with in the relevant position of pressing plate guide holder 4 and cover plate 9 for the fixing holddown groove of spacer pin 10.The lower end of pressing plate 2 is provided with guide plate 8 by bearing pin cylinder lever connecting rod 5 between pull bar 5 and the supporting seat 3, and pull bar 5 directions of motion are limited, and prevents that pull bar 5 from swinging.Pull bar 5 lower ends and connecting rod 7 are connected by bearing pin, the other end of connecting rod 7 is connected the middle part and is utilized bearing pin to connect with handle, handle 6 one ends and supporting seat 3 are hinged, by pulling the rotation of handle 6, can control pull bar 5 moves up and down, thereby pressing plate 2 is slided up and down, to reach the compression of workpiece and to get loose.
