Description

Technical Field

[0001] The invention relates to the technical field of bolt and nut assembly equipment, in particular to automatic assembly equipment for bolts and nuts. Background Art

[0002] In today's industrial production field, the assembly of bolts and nuts is a common and critical operation, which is widely used in machinery manufacturing, automobile industry, aerospace, electronic equipment manufacturing and the assembly process of various mechanical equipment. Bolts and nuts are usually used and sold in combination. Therefore, bolts and nuts are assembled in advance during the machinery production process to facilitate subsequent sales and supply. At present, the assembly of commonly used bolts and nuts mainly relies on manual operation. The personnel who manually assemble bolts and nuts are affected by some objective factors, and it is difficult to accurately control the tightening torque, and it is impossible to ensure that the tightening torque of each bolt and nut is the same, which affects the matching use or sales process. In addition, the efficiency of the manual assembly process is relatively low, which is difficult to meet the high efficiency requirements of large-scale industrial production.

[0003] The Chinese patent discloses an automatic assembly device for bolts and nuts based on pneumatic technology (authorization announcement number CN207309365U), which includes a base, screws and an automatic screw tightening component box, wherein a pneumatic lifting rod is installed on the top of the base through bolts, and a load-bearing frame is installed on the top of the pneumatic lifting rod through a bracket, an equipment room is installed on the top of the load-bearing frame, and an operating table is installed on the top of the equipment room through a connecting frame, an automatic screw tightening component box is installed on one side of the top of the operating table through a mounting rod, and a vibration plate is provided on the other side of the top of the operating table, a screw aligning machine is installed between the automatic screw tightening component box and the vibration plate, and the discharge trough of the vibration plate is connected to the feed port of the screw aligning machine, and a sliding groove is provided on the surface of the automatic screw tightening component box.

[0004] Although this patent can use a screw arranging machine to put the screws into place and put them in designated positions for tightening, during use, the screws are vibrated and sent out one by one through a vibration plate. During this process, the vibration may easily cause the bolts and nuts to fall off, and a robot is required to pick up the fallen bolts and nuts, which affects the assembly efficiency of the bolts and nuts. The bolts and nuts that fall on the ground need to be picked up manually and put back into the component box, further increasing the assembly cost. Therefore, the present invention provides an automatic assembly device for bolts and nuts to solve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide an automatic assembly device for bolts and nuts to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0010] As a further solution of the present invention, the adjustment assembly includes an I-shaped shaft, one end of the I-shaped shaft is rotatably connected to the first support rod, a half-open shaft is provided at one end of the I-shaped shaft close to the adjustment gear, and the other end of the I-shaped shaft is fixedly connected to a paddle.

[0011] As a further solution of the present invention, the outer circumference of the adjusting gear is respectively provided with eight arc-shaped openings and eight rod-shaped openings, the half-open shaft can rotate at the arc-shaped openings, and the paddle can move at the rod-shaped openings.

[0012] As a further solution of the present invention, the bolt adjustment plate is fixedly connected to one end of the movable rod close to the eight-sided rotating drum, and a plurality of openings are opened on the outer wall of the bolt adjustment plate. Each of the openings is rotatably connected to a bolt adjustment assembly for adsorbing a bolt and rotating the bolt to connect it with a nut.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1.

At the same time, the rotating connecting shaft will drive the first connecting rod to perform circular motion around it, and at the same time drive the second connecting rod to perform circular motion, and the second connecting rod will drive the third connecting rod and the fourth connecting rod to perform ninety-degree reciprocating motion. At the same time, under the limiting action of the fourth connecting rod and the adjusting block, the movable rod moves back and forth on the adjusting block along the slide groove. In this way, the bolt adjusting plate automatically performs reciprocating motion under the drive of the motor and various components, and continuously and automatically assembles the bolts adsorbed on the bolt adjusting assembly with the nuts on the eight-sided rotating drum, thereby achieving an efficient and automated automatic assembly effect of bolts and nuts.

[0034] The working principle of the present invention is:

[0035] When the present invention is used, the driving motor 5 drives the end of the I-shaped shaft 401 close to the semi-open shaft 403 to rotate, and the other end of the I-shaped shaft 401 will make a circular motion, and drive the raised shaft and the semi-open shaft 403 to rotate and the paddle 402 to make a circular motion. When the paddle 402 rotates to the rod-shaped opening 302, the paddle 402 will drive the adjusting gear 3, the connecting shaft 20 and the eight-sided rotating drum 2 to rotate at the same time, and at this time, the protrusion between the arc-shaped opening 301 and the rod-shaped opening 302 is just located at the notch of the semi-open shaft 403, so as not to hinder the rotation of the adjusting gear 3. When the paddle 402 does not rotate to the rod-shaped opening 302, this When the adjusting gear 3 does not rotate, the first connecting rod 6 makes a circular motion around the connecting shaft 20, and drives the second connecting rod 7 to make a circular motion around the part connected with the first connecting rod 6. Since the third connecting rod 21 and the fourth connecting rod 8 are fixedly connected together, the second connecting rod 7 drives the third connecting rod 21 and the fourth connecting rod 8 to make a reciprocating motion of 90 degrees. Under the limiting action of the fourth connecting rod 8 and the adjusting block 18, the movable rod 9 makes a horizontal and vertical reciprocating motion on the adjusting block 18 along the slide groove, thereby driving the end of the bolt adjusting plate 10 close to the eight-sided rotating drum 2 to make a cyclic reciprocating motion between the base 1 and the eight-sided rotating drum 2.

[0036] A nut placing plate 14 is placed above the lifting plate 12. When the nut placing plate 14 is lifted, the nut placing plate 14 will be adsorbed on the outer wall of the eight-sided rotating drum 2 under the action of magnetic attraction, and then rotated under the cooperation of the adjusting gear 3 and the adjusting assembly 4. When the nut placing plate 14 just faces the bolt adjustment plate 10, the bolt adjustment plate 10 will just align with one end of the eight-sided rotating drum 2 and move toward it under the coordinated movement of the first connecting rod 6, the second connecting rod 7, the third connecting rod 21 and the fourth connecting rod 8. At this time, the bolts on the bolt adjustment plate 10 will just align with the bolts on the nut placing plate 14. The nut is connected with the nut under the action of the bolt adjustment assembly 19, and when the nut placing plate 14 continues to move to the end away from the bolt adjustment plate 10, the nut placing plate 14 is removed from the top of the eight-sided rotating drum 2 to obtain the assembled bolts and nuts. The device has a plurality of replaceable bolt placing plates 11 and nut placing plates 14. During use, only the bolt placing plates 11 and nut placing plates 14 on which the bolts and nuts are placed need to be replaced to continuously obtain the assembled bolts and nuts, thereby greatly improving the efficiency of bolt and nut assembly.
