Referring to fig. 1, the present invention provides a technical solution: this device is by erection support 1, fixing support 2, cylinder 3, magnetic switch 4, No. two magnetic switch 5, guide arm 6, the movable block 8, locating pin 9, No. two locating pins 10, uide bushing 11, long waist hole 12, guard plate 13 and the pre-thrust handle 7 part are constituteed, erection support 1 is connected with

fixing support

2, 3 one end of cylinder are connected with fixing support 2, fixing

support

2 and 3 junctions of cylinder are provided with the opening, the cylinder piston rod gets into inside fixing support 2 from this opening, two magnetic switch are equipped with on the other end upper portion of cylinder 3, fixing support 2 is inside arranged in to guide arm 6, the one end and the 3 piston rod fixed connection of cylinder of guide arm 6, hinged joint in the middle of the other end and the movable block 8 of guide arm 6. Two sides of the movable block 8 are hinged with a first positioning pin 9 and a second positioning pin 10, one end of the fixed support 2 far away from the cylinder 3 is provided with two guide holes, one end of the first positioning pin 9 and the second positioning pin 10 far away from the movable block 8 is arranged in the guide holes, two ends of the movable block 8 are provided with grooves, two corresponding through holes are respectively arranged on the upper and lower sides of the surface vertical to the grooves, one end of the first positioning pin 9 and the second positioning pin 10 close to the cylinder 3 is arranged in the grooves of the movable block 8 and is hinged with the movable block 8, one side of the middle part of the movable block 8 close to the cylinder 3 is provided with a long waist hole 12, one end of the guide rod 6 far away from the cylinder 3 is arranged in the long waist hole 12 and is hinged with the movable block 8, when the movable block 8 rotates by a certain angle, the movable block can interfere with the guide rod 6 and stop rotating, so that the movable block 8 can rotate by a certain angle through the formed lever mechanism, and the two positioning pins can move by different strokes.

Two magnetic switches are arranged at one end, far away from the guide rod 6, of the piston in the cylinder 3, and signals can be generated when one end, far away from the guide rod 6, of a piston rod of the cylinder is communicated with the two magnetic switches. The magnetic switch on the cylinder 3 is used for judging whether the position of the cylinder piston is at the designated position, and then the positioning state of the clamp and the installation state of the product are judged according to the signal of the magnetic switch. The end of the two positioning pins far away from the movable block 8 is conical, and the size of the conical tail end is larger than that of the hole of the product to be measured. And a guide sleeve 11 is respectively arranged in the two guide holes of the fixed support 2 to reduce the loss caused by the friction between the positioning pin and the guide holes on the fixed support 2 in the work process.

The fixed support 2 is provided with a pre-pushing handle 7 on one side far away from the mounting support 1, the guide rod 6 is fixedly connected with one end of the pre-pushing handle, a protection plate 13 is fixedly connected in the middle of the pre-pushing handle 7 and can move together with the pre-pushing handle 7, the other end of the pre-pushing handle 7 extends out of the fixed support 2, and the handle 7 is manually pushed before the machine runs to ensure that the first positioning pin 9 and the second positioning pin 10 move normally.

The basic process is as follows: after the cylinder 3 ventilates, the cylinder work promotes the movable block 8 and a locating pin 9 and No. two locating pins 10 that the guide arm 6 is connected and moves forward, and a locating pin 9 and No. two locating pins 10 pass the hole of product outside and get into the hole of product inside, because a locating pin 9 and No. two locating pins 10 front end is the tapering and the size of tapering tail end is greater than the hole of product inside, so can produce following three kinds of condition:

1, when the internal product has no neglected loading, the sizes of the front taper tail ends of the first positioning pin 9 and the second positioning pin 10 are larger than the sizes of the holes of the product 14 and the product 15, and the positioning pins are subjected to resistance, so that the piston of the cylinder 3 cannot continue to move forwards and stop. The first magnetic switch 4 is communicated with the piston at the moment and is in a signal state, please refer to fig. 2, so that the condition that the product is not neglected to be installed is judged;

2, when the product in the cylinder has a neglected loading, the positioning pin 9 can be stopped advancing by resistance due to the obstruction of the product 15, the positioning pin 10 can continue advancing without resistance, the movable block 8 rotates anticlockwise, the movable block interferes with the guide rod 6 after reaching a certain angle, and the piston guide rod of the cylinder 3 stops advancing. The first magnetic switch 4 is in a no-signal state at this time, please refer to fig. 3, thereby determining that the product is not loaded.

3, when all the internal products are neglected to be installed, the first positioning pin 9 and the second positioning pin 10 cannot be subjected to resistance force due to no product obstruction and continue to move forwards until the stroke of the cylinder 3 is finished, and the first magnetic switch 4 is in a no-signal state at the moment, please refer to fig. 4, so that the neglected installation of the products is judged.

After the product is processed, the cylinder 3 returns to the initial position, and the second magnetic switch 5 is in a signal state at the moment, so that the product is taken out.

Before the air cylinder is ventilated, the pre-pushing handle is slowly pushed towards the advancing direction of the piston rod of the air cylinder, so that the two positioning pins can completely extend out of the two guide sleeves, and then the air cylinder is ventilated to ensure that the equipment can normally work.

Of course, the pre-pushing handle 7 can be replaced by other modes, for example, a small force is loaded before the cylinder 3 works, so that the cylinder 3 does little work, the guide rod 6 is pushed to advance by a small force, and the purpose of detecting whether the first positioning pin 9 and the second positioning pin 10 work properly can be achieved, and the whole device cannot be damaged. If the structure is adopted, a fixed protection plate can be directly installed on one side of the fixed support 2 far away from the installation support 1. Similarly, the connection between the first positioning pin 9 and the second positioning pin 10 and the movable block 8 and the connection between the movable block 8 and the guide rod 6 are not limited to the hinge connection, and other connection methods, such as a pin connection, may be adopted. The cross-sectional shape of the fixing support is not limited to a rectangle, and other suitable shapes can be provided. Such variations fall within the scope of the present invention.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
