Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 4, a simplified positioning tube and positioning column combined positioning device for wrist arm assembly, a positioning column 16 is fixedly connected with a hoop 17, the positioning tube is fixedly connected with a monaural connecting plate, a pin hole is formed in the monaural connecting plate, the positioning tube comprises a positioning column positioning unit 1 and a positioning tube positioning unit 5, a plurality of supporting units are arranged between the positioning column positioning unit 1 and the positioning tube positioning unit 5, and all the supporting units are distributed along a straight line.
The positioning column positioning unit 1 comprises a positioning boss 8 fixedly arranged, and the positioning boss 8 is used for being matched with the hoop 17.
The positioning tube positioning unit 5 comprises a fixedly arranged positioning pin 19, and the positioning pin 19 is used for being matched with the pin hole.
When the positioning upright post 16 needs to be positioned, the positioning upright post 16 is placed on the supporting unit by using a robot, and the positioning boss 8 is inserted into the center hole of the hoop 17 in the process, so that the hoop 17 is positioned by using the positioning boss 8, the position of the positioning upright post 16 is also fixed under the condition that the position of the hoop 17 is determined, and the positioning of the positioning upright post 16 is realized. When the positioning tube needs to be positioned, the positioning tube is moved to the supporting unit by a robot, the positioning pin 19 is inserted into the pin hole to fix the position of the single-lug connecting plate in the process, and the position of the positioning tube is fixed under the condition that the position of the single-lug connecting plate is fixed, namely, the positioning of the positioning tube is realized.
The utility model discloses can enough fix a position the stand 16 and also can fix a position the registration arm to realize the location according to the structure of location stand 16 and registration arm itself, positioning speed is fast, and the precision is high.
In order to ensure that the positioning boss 8 can be smoothly inserted into the center hole of the hoop 17 and avoid the reduction of efficiency caused by frequently calibrating the position of the hoop 1 by the robot, the positioning boss 8 is conical, and the diameter of the large end of the positioning boss 8 is smaller than or equal to the aperture of the center hole of the hoop 17. After the pointed end of the positioning boss 8 is inserted into the center hole, the positioning boss 8 is in contact with the inner wall of the center hole to guide the hoop 17, so that the position of the hoop 17 does not need to be frequently adjusted by a robot, the positioning speed is accelerated, and the efficiency is improved.
In order to ensure the positioning accuracy of the positioning column 16, it is necessary to ensure that the positioning boss 8 can accurately position the hoop 17, the diameter of the large end of the positioning boss 8 is smaller than the aperture of the central hole, the pushing cylinder 12 is arranged on the side of the positioning boss 8, and the piston rod of the pushing cylinder 12 is parallel to the connecting lines of all the supporting units. Under the condition that the diameter of the large end of the positioning boss 8 is smaller than the aperture of the central hole, the positioning boss 8 cannot be completely attached to the inner wall of the central hole after extending into the central hole, so that the positioning accuracy is reduced, and in order to avoid the condition, the position of the hoop 17 is adjusted by pushing the cylinder 12, so that the positioning accuracy is ensured. Specifically speaking, the hoop 17 includes movable hoop plate 28 and fixed hoop plate 29, movable hoop plate 28 and fixed hoop plate 29 all are the semicircle ring-type, movable hoop plate 28 is articulated with fixed hoop plate 29, fixed hoop plate 29 and location stand 16 fixed connection, after location boss 8 enters into the centre bore, push cylinder 12 promotes fixed hoop plate 29 and removes, until fixed hoop plate 29 with the laminating of location boss 8 can, no matter after location boss 8 enters into the centre bore location boss 8 with the position relation of hoop 17 how, can both promote staple bolt 17 to fixed position through push cylinder 12, consequently, the effect of guaranteeing positioning accuracy has been realized.
Because fixed hoop plate 29 is the semicircle annular, in order to guarantee that push cylinder 12 can not cause location hoop plate 29 to deflect at the in-process that pushes away location hoop plate 29, push cylinder 12 drive is connected with and promotes piece 10, has seted up spacing groove 9 on promoting piece 10, and the extending direction of spacing groove 9 is parallel to each other with the axis of location boss 8. The spacing groove 9 sets up to V type groove to the width of spacing groove 9 is greater than the external diameter of fixed hoop board 29, and the drive promotes the piece 10 and removes after promoting cylinder 12 to start, and when promoting piece 10 and fixed hoop board 29 contact, fixed hoop board 29 enters into spacing groove 9 and is spacing by spacing groove 9, thereby guarantees can not take place to deflect at the removal in-process.
Location stand positioning unit 1 still includes bottom plate 6, location boss 8 and the equal fixed setting on bottom plate 6 of push cylinder 12, the spout has been seted up on bottom plate 6, the extending direction of spout is parallel to each other with the piston rod that pushes cylinder 12, push cylinder 12 drive is connected with movable block 11, movable block 11 slides and sets up in the spout and with push block 10 fixed connection, still fixed being provided with brace table 7 on bottom plate 6, location boss 8 is fixed to be set up on brace table 7, brace table 7 is cylindricly, the diameter of 8 main aspects of location boss is less than the diameter of brace table 7, and location boss 8 and the coaxial setting of brace table 7.
In order to further improve the positioning accuracy, the positioning column positioning unit 1 includes a positioning plate 13 vertically disposed on the side of the positioning boss 8, a positioning groove 14 is opened on the positioning plate 13, the positioning groove 14 is a V-shaped groove, and the bottom of the positioning groove 14 is lower than the bottom of the positioning boss 8. The positioning plate 13 is used for supporting the positioning column 16 on one hand, and is used for limiting the positioning column 16 through the positioning groove 14 on the other hand, so that the positioning column 16 is parallel to the connecting lines of all the supporting units after being placed, and the positioning accuracy is further ensured.
In order to ensure that the positioning upright post 16 is placed and then the pushing cylinder 12 is started, the positioning plate 13 is fixedly provided with an opposite photoelectric sensor 15, the detection light of the opposite photoelectric sensor 15 is parallel to the width direction of the positioning groove 14, and the detection light is higher than the bottom of the positioning groove 14. The detection light is cut off after the positioning column 16 enters the positioning groove 14, so that the positioning column 16 can be determined to be placed in place, and the positioning column 16 can be accurately positioned by using the pushing cylinder 12.
Although can fix a position the registration pin through the cooperation of locating pin 19 with the pinhole, locating pin 19 also can insert in the pinhole when the monaural connecting plate appears the slope, lead to positioning accuracy to descend, in order to avoid this condition to appear, registration pin positioning unit 5 drives actuating cylinder 23 including the fixed briquetting level that sets up 19 sides at the locating pin, and the briquetting level drives actuating cylinder 23's piston rod and all support element's line and is parallel to each other, the briquetting level drives actuating cylinder 23 drive and is connected with the briquetting and drives actuating cylinder 21 perpendicularly, the briquetting drives actuating cylinder 21's piston rod downwards and sets up and fixedly connected with briquetting 27 perpendicularly, the bottom of briquetting 27 is seted up with locating pin 19 assorted jack.
