Abstract
A plastic gear rack transmission device for a mechanical arm is used for the reciprocating motion of a mechanical arm slide arm of a knockout machine. A motor is fixed to a speed reducer, a drive gear is in shaft connection with the speed reducer, the speed reducer is arranged on a speed reducer fixing plate, the speed reducer fixing plate is connected with a unit support, a guide rail is arranged on the left side face of the slide arm, sliding blocks are arranged on the unit support, the sliding blocks are fixedly locked with the guide rail, a plastic gear rack moulded in an injection mode is assembled parallel to the guide rail on the left side face of the slide arm, the plastic gear rack is of a two-side symmetric structure, the drive gear is meshed with the plastic gear rack, and the unit support is provided with an adjusting screw. The motor rotates to drive the drive gear to rotate, the drive gear rotates to drive the plastic gear rack to move, and each unit of the mechanical arm is made to carry out reciprocating motion under the matching action of a power device and a guide mechanism. Cost is greatly lowered, meanwhile, the defects that the mechanical arm of an existing knockout machine is heavy and high in transmission noise are overcome, and the plastic gear rack transmission device is simple in structure and production process, convenient to mount and maintain, light and low in transmission noise.
Description
Technical field
The present invention relates to industrial automation technical field, specifically a kind of for utilizing gear driven plastics tooth bar on knockout machine manipulator, by gyration, be converted to straight-line transmission device.
Background technology
At present, the kind of drive that common knockout machine manipulator uses can be divided into following two kinds: a kind of is to drive toothed belt transmission by synchronous pulley, and this kind of drive is installed and regulated too loaded down with trivial details, inconvenience dismounting and maintenance; Another kind is by irony gear driven irony rack-driving, this kind of drive has solved the former and has installed that adjusting is too loaded down with trivial details, the problem of inconvenient detachable maintaining, but irony tooth bar has the shortcomings such as transmission noise is large, weight is large, equally also can not meet the requirement that modern knockout machine manipulator quality is light, speed is fast, noise is little.
Summary of the invention
For solving the deficiency that existing knockout machine robot manipulator structure is complicated, heavy, transmission noise is large, goal of the invention of the present invention is to provide a kind of manipulator plastics rack gearing, easy to realize installation and maintenance, the object that transmission noise is little.
For achieving the above object, motor of the present invention is fixed on reductor, driven wheel is connected with the axle of reductor, reductor is contained on reductor fixed head, reductor fixed head is connected with unit rack, on the left surface of cursor slide, guide rail is installed, the slide block that can slide on guide rail is housed on unit rack, slide block and guide rail fixing and locking, on the left surface of cursor slide, be assemblied with the plastics tooth bar of injection forming with guide rail parallel, plastics tooth bar is bilateral symmetry structure, driven wheel and the engagement of plastics tooth bar, on unit rack, band is useful on the set screw that regulates driven wheel and plastics tooth bar back lash.
The present invention replaces toothed belt transmission and the transmission of irony rack-and-pinion of existing knockout machine manipulator with plastics rack-driving, plastics tooth bar production technology is injection mo(u)lding, the structure bilateral symmetry of tooth bar, this structure has solved the contraction distortions that tooth bar causes due to tooth bar both sides cooling velocity difference when moulding is cooling; For making up plastics tooth bar, wear no resistance, the deficiency that service life is short is added special wear-resisting composition in plastics tooth bar moulding material, has extended to a certain extent the service life of plastics tooth bars.
When motor rotates, drive driven wheel rotation, driven wheel rotarily drives the motion of plastics tooth bar, by the engaged transmission of driven wheel and plastics tooth bar, under the mating reaction of power set and guiding mechanism, manipulator unit is moved reciprocatingly.
The present invention compared with prior art, when greatly reducing knockout machine manipulator cost, has solved again the deficiency that existing knockout machine manipulator is heavy, transmission noise is large, and structure and production technology are simple, and installation, maintenance is convenient, lightweight, transmission noise is little.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Fig. 6, motor 5 is fixed on reductor 4, driven wheel 3 is directly installed on the axle of reductor 4, reductor 4 is screwed on reductor fixed head 7, reductor fixed head 7 use screws are arranged on above unit rack 6, a guide rail 8 is installed on cursor slide 1 left surface, two slide blocks 9 are installed on unit rack 6, slide block 9 is by screw and guide rail 8 fixing and lockings for reference for installation, the plastics tooth bar 2 of injection forming is installed with the parallel splicing of guide rail 8 on cursor slide 1 left surface, plastics tooth bar 2 is by screw and cursor slide 1 fixing and locking for reference for installation, plastics tooth bar 2 is bilateral symmetry structure, driven wheel 3 and 2 engagements of plastics tooth bar.
By outer-hexagonal set screw 10, regulate the back lash of driven wheel 3 and plastics tooth bar 2, then with spanner, reductor 4 and reductor fixed head 7 are locked, to guarantee that the driven wheel 3 of motor 5 in operation process can not change with the back lash of plastics tooth bar 2.
As shown in Figure 7, on Z axis, drive driven wheel 3 rotations during the rotation of the motor 5 of lower unit, driven wheel 3 rotarily drives plastics tooth bar 2 and moves up and down, thus the cursor slide 1 of realizing lower unit on knockout machine manipulator Z axis do rise, descending motion; When plastics tooth bar 2 is arranged on Y-axis front-and-back unit, the motor 5 of Y-axis front-and-back unit rotarily drives driven wheel 3 rotations, driven wheel 3 rotarily drive before and after Y-axis plastics tooth bar 2 do advance, setback, thereby realize arm before and after knockout machine manipulator Y-axis do advance, the motion of direction of retreat; The motor 5 that is arranged on Shi，XZhou unit, X-axis unit when plastics tooth bar 2 rotarily drives driven wheel 3 rotations, and gear 3 rotarily drives X-axis plastics tooth bar 2 and does left and right back and forth movement, thereby realizes the reciprocating motion that knockout machine manipulator X-axis is taken out side, fallen side direction.
