DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described below in combination with specific implementation methods. The drawings are only used for exemplary descriptions, and only show schematic diagrams rather than physical drawings, and cannot be understood as limitations of this patent; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0024] The utility model discloses a grease injection machine for a garage door shaft support assembly, comprising a workbench 1 arranged above a bracket, a support plate 2 being arranged on the top front side of the workbench 1 through a column, two groups of positioning components 3 being symmetrically arranged on the top of the support plate 2, the positioning component 3 comprising 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 being compatible with the garage door shaft support assembly and capable of fixing the garage door shaft support assembly; a guide rail 4 is arranged on the top rear side of the workbench 1 along its front and rear directions, a movable plate 5 is movably arranged on the guide rail 4 through a slider, a first cylinder 6 for driving the movable plate 5 to move back and forth is arranged on the top rear end of the workbench 1; two motors 8 are arranged in parallel on the top rear side of the movable plate 5 through an L-shaped support plate 7, a driving shaft end of the motor 8 is forwardly passed through the L-shaped support plate and is provided with a docking joint 27.

[0025] In this embodiment, since the motor drive shaft end extends relatively long, in order to ensure the stability of the drive shaft rotation, two bearing seats 28 are arranged side by side on the top of the movable plate 5 located on the front side of the L-shaped support plate 7, and the drive shaft end of the motor 8 passes through the L-shaped support plate 7 and the bearing seat 28 in turn. A connecting column is provided on the front end of the connecting column, and a docking joint 27 is provided.

[0026] The garage door shaft support assembly is a worm gear structure with a housing, used in pairs, and lubricating grease is added before the upper and lower housings are assembled. Figure 7 The figure shows a schematic diagram of the back structure of the lower shell of the garage door shaft support assembly, the back is the mating surface of the lower shell and the positioning component, the upper and lower parts of the back are respectively provided with convex strips 400, and the convex strips 400 extend from the circular area 100 of the lower shell to the rectangular area 200 of the lower shell, and the positioning plate can be arranged between the two convex strips to achieve positioning, and a bearing support 300 without bearing assembly is arranged in the center of the circular area 100 of the back, and 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 shell, and the rotating shafts at both ends of the worm extend out of the rectangular area of ​​the lower shell to relatively fix the worm, and a worm wheel is movably arranged in the circular area on the other side of the lower shell, and the upper end surface of the worm wheel is a plane. When in use, the lower shell of the garage door shaft support assembly equipped with a worm wheel and a worm is placed on the positioning component, the bearing support on the back of the lower shell is sleeved on the convex positioning column, the upper end of the convex positioning column is inserted into the through hole of the bearing support, and the lower end edge thereof is against the inner ring of the bearing support to play a supporting role, the positioning plate is just between the two convex strips in the rectangular area to achieve its fixation, and then the first cylinder is actuated to push the moving plate forward, so that the docking joint at the driving shaft end of the motor is connected to the rotating shaft at one end of the worm, and then the motor is actuated to rotate the worm, thereby driving the worm wheel to rotate. At this time, lubricating grease can be manually injected into the rectangular area of ​​the lower shell, and the worm rotates to rotate the lubricating grease to the worm wheel for even distribution.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Specifically, the third cylinder controls the opening or closing of the discharge valve in this way. The discharge valve 12 is provided with an adjustment channel 18 perpendicular to the oil passage 13 in the left and right directions, and an adjustment column 19 is movably arranged in the adjustment channel 18. The adjustment column 19 is provided with an oil passage hole 20 adapted to the oil passage 13. The telescopic shaft end of the third cylinder 17 is connected to one end of the adjustment column 19. When the third cylinder is actuated, the adjustment column can move back and forth to align or offset the oil passage hole with the oil passage, thereby opening or completely blocking the oil passage.

[0032] In this embodiment, in order to guide the adjusting column and ensure that it does not rub against the inner wall of the adjusting channel, flange limit plates 21 for blocking the adjusting through hole are provided on the left and right sides of the discharge valve 12. The diameter of the central through hole of the flange limit plate 12 is smaller than the diameter of the adjusting column, so that the adjusting column cannot extend from the adjusting channel. Limit rods 22 are provided at both ends of the adjusting column 19. The limit rods 22 extend from the central through hole of the flange limit plate 21. One limit rod 22 is connected to the telescopic shaft end of the third cylinder 17 through a connecting column, and the other limit rod is a free end.

[0033] Furthermore, in order to ensure the stability of the oil inlet pipe, a support plate 23 for supporting the feed pipe is provided on the rear side of the workbench 1 .

[0034] As a preferred method, it also includes a touch screen 25 and a start switch 26. A protective cover 24 is provided on the two protective plates on the top of the workbench, and the touch screen 25 and the start switch 26 are provided on the protective cover. The touch 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 to control their actions in sequence after startup. The injection time of the lubricating grease can be set by the touch screen, and the amount of the injected lubricating grease can be determined by the injection time (due to the stable and continuous pressure of the air source, the injection amount / minute can be calculated, and then the injection amount at 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 in sequence. In addition, an emergency stop switch and a reset switch are also included. In the event of danger, the machine can be shut down with one click through the emergency stop switch, and when the program is disordered, it can be restored to the factory value through the reset switch.
