Problems solved by technology

[0003] Most of the existing bolt assembly machines need to rotate the locking set and the hexagon on the bolt before assembly, and can only install the bolts at fixed positions separately. For some mass-produced workpieces or a When there are multiple equidistant bolt holes on the workpiece that need to be assembled, the degree of automation is not high enough, so that the entire transfer process takes a lot of time, which is not conducive to improving assembly efficiency

Embodiment 1

[0030] see Figure 1~4 , in an embodiment of the present invention, a robot for automatic production of bolt assembly includes a workbench 1, a side column 2 whose lower end is fixedly installed on the front side wall of the workbench 1, a top plate 3 fixed on the upper end of the side column 2, and a flange installed on the The upper part of the side column 2 is electrically connected to the electric motor 4 of the power supply and the switch, the worm 5 connected to the output end of the electric motor 4, the locking mechanism and the moving mechanism connected to the worm 5;

[0031] Specifically, the worm 5 passes through the side column 2 and is bearing-connected with it. The side of the worm 5 away from the electric motor 4 is sleeved on a sleeve fixed to the lower part of the top plate 3, and the electric motor 4 is powered on by starting the switch. Drive its work, and electric motor 4 work drives worm screw 5 to rotate.

[0032] Further, the locking mechanism include...

Embodiment 2

[0037] In order to achieve the continuous work function of automatic shifting of the workpiece and matching the hexagonal lock sleeve 13, in another embodiment of the present invention, a robot for automatic production of bolt assembly also includes a feeding mechanism, and the feeding mechanism includes a worm gear engaging the worm 5 17. The Maltese cross movement assembly connected with the worm gear 17, the gear 23 connected to the Maltese cross movement assembly, the rack 24 meshed with the gear 23 and fixed on the supporting plate 25, wherein the worm gear 17, the Maltese cross movement assembly and The gears 23 are all rotatably connected to the mounting frame 21 fixed on the back side of the workbench 1, the Maltese cross movement assembly is connected to the gear 23 through the second transmission belt 22, the rotating worm 5 drives the worm wheel 17 to rotate, and the worm wheel 17 drives the Maltese cross movement assembly The work then drives the gear 23 to rotate i...

Embodiment 3

[0041] An assembly method of a robot for automatic production of bolt assembly, comprising the steps of:

[0042] Step 1, reset, check whether the supporting plate is in the initial position under the gear, if not, press the switch in reverse to make the electric motor drive the worm to reverse and reset the supporting plate;

[0043] Step 2, installation, fix the workpiece on the pallet, and insert the bolts into the assembly holes;

[0044] Step 3, assemble, start the electric motor in the forward direction, use the locking mechanism and the moving mechanism to drive the hexagonal lock sleeve to move up and down reciprocally and rotate and lock, while the gear drives the pallet to feed intermittently;

[0045] Step 4, complete, turn off the switch after all the bolts on the supporting plate have passed through the hexagonal lock sleeve, remove the workpiece installed on the supporting plate, and check the locking condition of the bolts.

[0046] According to the specific de...

Abstract

The invention discloses a bolt assembling automatic production robot and an assembling method thereof. The problem that the existing bolt assembling automation degree is not high is solved. A lockingmechanism comprises a sleeve which penetrates through a top plate and is connected with the top plate through bearings, a bevel gear set connecting the sleeve with a worm, a moving shaft arranged on the sleeve in a sleeved manner, a square rod connected to the lower portion of the moving shaft in a sleeved manner, and a hexagonal lock sleeve fixedly mounted at the lower end of the square rod. Theworm is further connected with a moving mechanism through a first transmission belt. The bevel gear set comprises a first bevel gear fixed to the end, away from an electric motor, of the worm, and a second bevel gear engaged with the first bevel gear and fixed to the sleeve. Two through grooves are symmetrically formed in the inner wall of the sleeve. Limit bars matched with the through grooves inthe inner wall of the sleeve are symmetrically arranged on the outer wall of the moving shaft. The moving mechanism drives the locking sleeve to move up and down, meanwhile, the locking mechanism canfurther drive the moving locking sleeve to rotate, and multiple freedom degrees are achieved.

Description

technical field [0001] The invention relates to the field of industrial assembly, in particular to a robot for automatic production of bolt assembly and an assembly method thereof. Background technique [0002] Nuts and bolts are very common connecting parts in the machinery manufacturing industry. The usual assembly method is to insert the bolts into the holes in the components, and then use the rotation method to lock the bolts. [0003] Most of the existing bolt assembly machines need to rotate the locked set and the hexagon on the bolt before assembly, and can only install the bolts at fixed positions separately. For some mass-produced workpieces or a When a plurality of equidistant bolt holes on the workpiece need to be assembled, the degree of automation is not high enough, so that the entire transfer process takes a lot of time, which is not conducive to improving assembly efficiency. Contents of the invention [0004] Based on the deficiencies in the prior art men...
