[0022] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described below in conjunction with specific implementation manners. Among them, the attached drawings are only for illustrative purposes, showing only schematic diagrams, not physical diagrams, and should not be construed as limitations on this patent; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted

[0023] The grease injector for the garage door shaft support assembly of the present invention includes a workbench 1 arranged above a bracket. A support plate 2 is provided on the front side of the top of the workbench 1 through a column. Two groups of positioning components 3 are symmetrically arranged on the top of the support plate 2. The positioning component 3 includes a positioning column 3-1 and a positioning plate 3-2 arranged on one side of the positioning column 3-1. The structures of the positioning column and the positioning plate are adapted to the garage door shaft support assembly, and the fixation of the garage door shaft support assembly can be realized. A guide rail 4 is arranged on the rear side of the top of the workbench 1 along its front-back direction. A moving plate 5 is movably arranged on the guide rail 4 through a slider. A first cylinder 6 for driving the moving plate 5 to move back and forth is arranged at the rear end of the top of the workbench 1. Two motors 8 are arranged in parallel on the rear side of the top of the moving plate 5 through an L-shaped support plate 7. The driving shaft end of the motor 8 passes forward through the L-shaped support plate and is provided with a docking head 27.

[0024] In this embodiment, since the driving shaft end of the motor extends relatively long, in order to ensure the stability of the driving shaft rotation, two bearing seats 28 are arranged in parallel on the top of the moving plate 5 in front of the L-shaped support plate 7. The driving shaft end of the motor 8 passes forward through the L-shaped support plate 7 and the bearing seat 28 in sequence and is provided with a connecting column. The front end of the connecting column is provided with a docking head 27.

[0025] The garage door shaft support assembly is a worm and worm gear structure with a housing, and is used in pairs. Lubricating grease is injected before the upper and lower housings are assembled. Specifically, as Figure 7 shown is the schematic structural diagram of the back of the lower housing of the garage door shaft support assembly. This back is the mating surface between the lower housing and the positioning component. Convex strips 400 are respectively arranged on the upper and lower parts of this back, and the convex strips 400 extend from the circular area 100 of the lower housing to the rectangular area 200 of the lower housing. The positioning plate can be arranged between the two convex strips to achieve positioning. A bearing support 300 without an assembled bearing is arranged at the center of the circular area 100 of this back. The through hole of the bearing support corresponds to the positioning column. A worm is arranged in the rectangular area on the other side of the lower housing. The rotating shafts at both ends of the worm extend out of the rectangular area of the lower housing to make the worm relatively fixed. A worm gear is movably arranged in the circular area on the other side of the lower housing. The upper end surface of the worm gear is a plane. When in use, the lower housing of the garage door shaft support assembly equipped with the worm gear and the worm is placed on the positioning component. The bearing support on the back of the lower housing is sleeved on the convex positioning column. The upper end of the convex positioning column penetrates into the through hole of the bearing support, and the lower end edge thereof abuts against the inner ring of the bearing support to play a supporting role. The positioning plate is exactly between the two convex strips in the rectangular area to realize its fixation. Then the first cylinder acts to push the moving plate forward, so that the docking head at the driving shaft end of the motor is connected to the rotating shaft at one end of the worm. Then the motor acts to rotate the worm, and further drives the worm gear to rotate. At this time, lubricating grease can be manually injected into the rectangular area of the lower housing, and the worm rotates to further rotate the lubricating grease to the worm gear to achieve uniform distribution.

[0026] Among them, since the end of the worm shaft close to the motor is a regular hexagonal shaft with a through hole, the corresponding butt joint surface is provided with a regular hexagonal groove adapted to the regular hexagonal shaft, and a positioning column adapted to the through hole is arranged in the center of the groove. The butt joint surface is designed according to the shape of the worm shaft to ensure that the two can be matched and connected.

[0027] Considering that the worm gear is relatively movable in the lower housing, there may be a pop-up phenomenon when the worm rotates. Therefore, a top plate 9 is provided on the top rear side of the workbench 1 through a column, and two second cylinders 10 are provided on the front side of the top plate 9 through a vertical plate, and the push plate of the second cylinder 10 is vertically downward, and a T-shaped plate 11 is provided on the push plate of the second cylinder. The T-shaped plate 11 corresponds vertically to the positioning column, and the left and right sides of the T-shaped plate 11 are rotatably provided with rotating wheels 29 through a fixed shaft. After the lower housing of the garage door shaft support assembly equipped with a worm gear and a worm is placed on the positioning assembly and fixed, the second cylinder is started first, and moves downward to make the two rotating wheels abut against the upper end face of the worm gear, and is tangent to the upper end face, which not only presses the worm gear but also rotates with the worm gear, and then the first cylinder and the motor act successively.

[0028] In addition, in order to reduce the workload of workers, automatic filling of lubricating grease is realized. Two discharge valves 12 are arranged at the front side of the bottom of the top plate 9. An oil passage 13 is provided in the discharge valve 12 along its front and rear direction. The oil passage 13 penetrates the front side of the discharge valve to form an outlet, and the oil passage 13 penetrates the rear side of the discharge valve to form an inlet. The front outlet of the discharge valve 12 is connected to an L-shaped discharge pipe 14. The vertical pipe of the L-shaped discharge pipe 14 is located above the positioning plate and corresponds to it. The rear inlet of the discharge valve 12 is connected to a feed pipe 15, and the feed pipe 15 is connected to the oil tank through a guide pipe. The oil tank is a sealed oil tank, which is placed on one side of the workbench. The sealed oil tank is connected to the air source, and the air source continuously and stably enters the sealed oil tank, so that the lubricating grease in the sealed oil tank is discharged through the guide pipe, the feed pipe, the discharge valve, and the L-shaped discharge pipe under pressure, and flows into the rectangular area of ​​the lower shell, and then the lubricating grease is rotated to the worm gear to be evenly distributed. At this time, the discharge and cutting off of lubricating grease can be controlled by controlling the shutdown of the air source.

[0029] Since some lubricating grease will still flow out after the air source is shut down in the above method, in order to improve the degree of automation, add lubricating grease relatively accurately, and further reduce costs, protective plates 16 are provided on the left and right sides of the top of the workbench 1, and a third cylinder 17 is provided on the inner side of the protective plate 16. The third cylinder 17 is used to control the opening or closing of the discharge valve 12.

[0030] Specifically, the third cylinder controls the opening or closing of the material discharge valve in this way. An adjustment channel 18 perpendicular to the oil passage 13 is provided in the left-right direction of the material discharge valve 12. An adjustment column 19 is movably arranged in the adjustment channel 18. An oil passage through hole 20 adapted to the oil passage 13 is provided on the adjustment column 19. The telescopic shaft end of the third cylinder 17 is connected to one end of the adjustment column 19. When the third cylinder acts, the adjustment column can move back and forth to align or stagger the oil passage through hole with the oil passage, thereby opening or completely blocking the oil passage.

[0031] In this embodiment, in order to guide the adjustment column and ensure that it does not rub against the inner wall of the adjustment channel, flange limit disks 21 for blocking the adjustment through hole are arranged on both the left and right sides of the material discharge valve 12. The diameter of the central through hole of the flange limit disk 12 is smaller than the diameter of the adjustment column, so that the adjustment column cannot extend out of the adjustment channel. Limit rods 22 are arranged at both ends of the adjustment column 19. The limit rods 22 extend out from the central through hole of the flange limit disk 21. One limit rod 22 is connected to the telescopic shaft end of the third cylinder 17 through a connecting column, and one limit rod is a free end.

[0032] Further, in order to ensure the stability of the inlet pipe, a support plate 23 for supporting the feed pipe is arranged on the rear side of the workbench 1.

[0033] Preferably, it further includes a touch display screen 25 and a start switch 26. A protective cover 24 is arranged on the two protective plates at the top of the workbench. The touch display screen 25 and the start switch 26 are arranged on the protective cover. The touch display screen is connected to the control chip, and the control chip is respectively connected to the first cylinder, the motor, the second cylinder, and the third cylinder, and controls their sequential actions after startup. The injection time of the lubricating grease can be set through the touch display screen, and the amount of the injected lubricating grease can be determined by the injection time (since the air source applies pressure stably and continuously, the injection amount per minute can be calculated, and then the injection amount corresponding to the corresponding time can be obtained). After the start switch is turned on, the second cylinder, the first cylinder, the motor, and the third cylinder act sequentially. In addition, it further includes an emergency stop switch and a reset switch. In case of danger, the machine can be stopped immediately through the emergency stop switch. When the program goes wrong, it can be restored to the factory value through the reset switch.
