[0036] The utility model is provided with a bidirectional output module 4, and the two glue coating heads 7 can be synchronously changed in position through a frame 1 and a position changing mechanism 5, so that the threaded holes on the left and right sides of the bridge housing of the driving axle 9 are glued at the same time, which greatly improves the glue coating efficiency of the threaded holes, does not require manual operation, avoids the defects of uneven coating and missing coating of the threaded holes in the prior art, and realizes the rhythm consistency and stable production capacity of automated production.

[0037] like Figure 3 and Figure 4 As shown, a balancing mechanism 6 for balancing the support frame 43 is further provided between the support frame 43 and the moving cross bar 3 in this embodiment; the balancing mechanism 6 includes two balancing guide rails 61 provided at both ends of the moving cross bar 3 along the X-axis direction, the two balancing guide rails 61 are respectively located at both ends of the bidirectional ball screw 42, and a balancing slider 62 cooperating with the balancing guide rails 61 is installed on the support frame 43.

[0038] It is further explained that the frame 1 includes at least two columns 11 and a mounting frame 12 mounted on the top of the column 11; the mounting frame 12 extends from the column 11 in the Y-axis direction. The position change mechanism 5 is mounted on the mounting frame 12, and the bearing platform 2 is arranged in a cavity in the frame 1 to prevent the frame 1 from interfering with the gluing head 7 during the gluing process. The support frame 43 in this embodiment is in the shape of a "7", and the gluing head 7 is mounted on the lower end of the support frame 43. The gluing directions of the two gluing heads 7 are relatively set, and the gluing directions of the two gluing heads 7 are relatively set, respectively corresponding to the threaded holes to be glued at both ends of the driving axle 9 shell, to ensure that the threaded holes at both ends of the driving axle 9 shell are glued synchronously.

[0039] As an implementation mode, the glue coating head 7 is installed on the support frame 43 through the glue coating mounting seat 8, and the glue coating head 7 is clamped with the glue coating mounting seat 8. The clamping mode is adopted to facilitate the replacement and installation of the glue coating head 7.

[0040] As an embodiment, the position changing mechanism 5 includes a Y-axis displacement module 51 for driving the moving crossbar 3 to move in the Y-axis direction and a Z-axis displacement module 52 for driving the moving crossbar 3 to move in the Z-axis direction, wherein the Z-axis displacement module includes a Z-axis displacement frame 521, a Z-axis displacement servo motor 522 mounted on the Z-axis displacement frame 521, and a Z-axis moving plate 523 connected to the output shaft of the Z-axis displacement servo motor 522 through a Z-axis moving module, and the Z-axis moving plate 523 is arranged parallel to the moving crossbar 3 and connected through a Z-axis guide assembly 524. When in use, the Z-axis displacement servo motor 522 is started, and the moving crossbar 3 moves along the Z-axis direction following the Z-axis moving plate 523.

When in use, when the Z-axis displacement servo motor 522 is started, the Z-axis moving plate 523 is driven to move up and down through the Z-axis moving module, that is, under the guiding action of the Z-axis guiding column, the moving cross bar 3 is driven to move up and down along the Z-axis, thereby realizing the position change of the glue coating head 7 in the Z-axis direction.

[0042] Reference Figure 6 , the Y-axis displacement module 51 includes a Y-axis displacement motor 511 installed on the mounting frame 12, and the Z-axis displacement frame 521 is connected to the Y-axis displacement motor 511 through the Y-axis moving module 512; at least one set of Y-axis guide components 513, the Y-axis guide components 513 include a Y-axis guide rail 5131 fixedly installed on the mounting frame 12, a Y-axis slider 5132 matched with the Y-axis rail, and the Y-axis slider 5132 is fixedly connected to the lower end surface of the Z-axis displacement frame 521. In this embodiment, there are two sets of Y-axis guide components 513, which are respectively installed on both sides of the X-axis of the mounting frame 12, wherein the Y-axis moving module 512 is installed on the mounting frame 12 between the two Y-axis guide components 513, to ensure the synchronization and stability of the Y-axis movement of the two support frames 43.

[0043] It should be understood that the Z-axis moving module and the Y-axis moving module 512 in this embodiment are both screw-nut substructures, and may also be other moving module structures that can be thought of by technical personnel in this field. The specific structures of the Z-axis moving module and the Y-axis moving module 512 are not elaborated in detail here.

[0044] like Figure 1As shown, the bearing platform 2 in this embodiment includes a bearing frame 21 arranged inside the frame 1 and a tray 22 slidably mounted on the bearing frame 21; the driving axle 9 is mounted on the tray 22, and the threaded holes to be glued on the driving axle 9 correspond to the glue coating head 7. The tray 22 is slidably mounted between the bearing frame 21. When in use, the position of the tray 22 can be automatically controlled, that is, the position of the driving axle 9 can be automatically controlled to move the driving axle 9 to the glue coating position. The change of the position of the tray 22 and the replacement of the glue coating head 7 can ensure that the device is suitable for the glue coating of the threaded holes of various forklift driving axle 9 assemblies, ensuring the wide applicability of the glue coating device of this application.

[0045] It is further explained that a control box is also provided in this embodiment, and the control box is installed on the frame 1 or the carrying platform 2, and is used to control the position change of the glue coating head 7 and the glue coating operation. The specific control process of the glue coating device is as follows:

[0046] This embodiment takes a type of forklift drive axle 9 axle housing as an example, and includes the following control steps:

[0047] First, wait for the pallet 22 to be in place, read the workpiece model, and call the corresponding recipe; start the position change mechanism 5 to adjust the position of the glue coating head 7, that is, start the Z-axis displacement servo motor 522 and the Y-axis displacement servo motor to cooperate and move the two glue coating heads 7 to the first threaded hole position; secondly, start the bidirectional output servo motor 41, and move the glue coating head 7 deep into the corresponding threaded hole. At the same time, open the glue outlet valves of the two glue coating systems, and the glue coating head 7 moves forward while throwing glue to evenly apply the anaerobic glue on the inner wall of the threaded hole. After the bidirectional output servo motor 41 is in place, the glue outlet valve stops, and the bidirectional output servo motor 41 returns to the waiting position. The first threaded hole is glued, and finally the remaining threaded holes are glued in turn until the threaded holes are glued. After completion, the Z-axis displacement servo motor 522, the Y-axis displacement servo motor and the bidirectional output servo motor 41 return to their original positions. After the forklift drive axle 9 after gluing is moved out, the gluing work of the next workpiece is carried out.

[0048] The gluing device of the utility model is arranged with two left-right symmetrical gluing parts, adopting a set of truss manipulators, and utilizing a bidirectional roller screw to realize synchronous displacement and simultaneous feeding of the two sets of gluing systems, thereby improving the effect and saving costs. It is also applicable to the gluing process of the threaded holes of drive axles 9 of different models, different numbers of threaded holes, different positions of threaded holes, and different depths of threaded holes. The manual discrete operation mode of gluing the threaded holes is integrated and designed to form a set of automated system, saving at least two workers, reducing labor costs, and improving the degree of automation in the production of drive axles 9.

[0049] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
