Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic motors, and particularly to a hydraulic motor assembly and conveying line. Background Art

[0002] In the prior art, with the increasingly wide use of hydraulic motors, the assembly of hydraulic motors has become increasingly important. To simplify the assembly of hydraulic motors, assembly lines for hydraulic motors have emerged. Since there are many assembly procedures for hydraulic motors, multiple assembly stations are required. For example, the document with the application number CN202311228695.4 discloses a production line for assembling hydraulic motors, including a conveying line with a frame body. Along the conveying direction of the conveying line on the frame body, a glue dispensing mechanism, a screw driving mechanism, an alignment mechanism, and a marking mechanism are sequentially arranged. This enables the production line to automatically dispense glue, drive screws, and mark, with a high degree of automation, greatly reducing labor costs. The glue dispensing mechanism, the screw driving mechanism, the alignment mechanism, and the marking mechanism are connected by tracks. The specific structure is as follows: Tracks are arranged on the frame body, and baffles for blocking the tracks are arranged on the side of the frame body. The motors for assembly operations are assembled on tooling plates. A conveying mechanism for driving the tooling plates to move by frictionally abutting against the tooling plates is arranged on the tracks. Blocking mechanisms are arranged on the frame body at intervals greater than the length of the tooling plates along the tracks. This enables the motors to enter the working positions orderly.

[0003] The production line for assembling hydraulic motors in the above document can achieve the automatic assembly of hydraulic motors. However, the working mechanisms of the entire production line are connected as a whole through tracks. Since the assembly procedures of hydraulic motors are cumbersome, this results in a high cost, large volume, and large space occupation for the production line. Summary of the Invention

[0015] Based on the above technical solutions, the technical effects that the present invention can achieve are as follows: 1. The hydraulic motor assembly conveying line of the present invention includes a conveying module and a transfer device. The transfer device can realize the transfer of workpieces on different conveying modules. The hydraulic motor assembly conveying line can be provided with multiple conveying modules, and the transfer device is used to play a transfer role between the conveying modules. Therefore, the production line does not need to be integrally arranged, which can effectively reduce the cost and save space; by setting a guiding module at the feeding end or the discharging end of the conveying rack, the transfer device can complete the accurate docking with the conveying module along the guiding module, which is convenient to operate and has high flexibility; 2. In the hydraulic motor assembly conveying line of the present invention, a driving module for driving the tray to lift is further arranged on the conveying rack. The positioning module of the driving module can be inserted and positioned with the tray, and then the positioning module drives the tray to rise to facilitate the processing of the workpiece on the tray; after the processing is completed, the positioning module descends, and the tray can fall on the truss and be continuously conveyed; 3. In the hydraulic motor assembly conveying line of the present invention, guiding strips are arranged on the two ground rails of the guiding module, and the inclined surface at the entrance end of the guiding strip is arranged to facilitate guiding the roller group to enter along the ground rail; an infrared sensor and a signal lamp structure are arranged on the first cross beam in a staggered manner and are correspondingly matched with the reflecting surface on the moving carrier. When both infrared sensors receive the reflected signal, it means that the moving carrier is aligned with the entrance ends of the guiding strips on the two ground rails. Then, only by pushing the moving carrier in the extending direction of the ground rail can it enter the ground rail; 4. In the hydraulic motor assembly conveying line of the present invention, a second cross beam is arranged, and a proximity switch and a locking structure are arranged on the second cross beam. A locking rod is correspondingly arranged on the moving carrier, so that the automatic locking of the locking rod entering the locking range of the locking structure can be realized, and then the position of the moving carrier is fixed, so that the transfer device is in an accurate docking position with the conveying module, and further the transmission of the workpiece is realized; 5. For the hydraulic motor assembly conveyor line of the present invention, the 4 roller modules of the roller group are linked by a linkage rod, which can ensure that the movement directions of the 4 roller modules are the same. The driving rod can drive and control the direction of the roller group. Through the cooperation of the locking tongue on the driving rod and the movable lock on the moving carrier, the adjustment and locking of the movement direction of the roller group can be achieved. When the transfer device needs to be docked with the conveying module, the direction of the roller group can be adjusted first through the driving rod, and the movable lock locks the locking tongue, so that the transfer device can move along the direction parallel to the conveying module. Until the transfer device is successfully aligned with the ground rail, the movable lock is unlocked; then the direction of the roller group is adjusted by the driving rod to rotate 90 degrees, and the movable lock locks the locking tongue again, and the transfer device can be pushed to move along the ground rail until the locking rod on the moving carrier is locked by the locking structure, and the docking between the transfer device and the conveying module is completed.

The guiding module 1 is arranged at the feeding end and / or the discharging end of the conveying module 3. The guiding module 1 guides the transfer device 2. Under the guiding action of the guiding module 1, the transfer device 2 can move to the feeding end or the discharging end of the conveying module 3 and dock with the conveying module 3.

[0024] The guiding module 1 is fixed to the feeding end or the discharging end of the conveying module 3.

[0025] As a preferred technical solution of this embodiment, in order to facilitate the transfer device 2 to enter the ground rail 11, guiding strips 12 are arranged on the surfaces of the two ground rails 11 that cooperate with the transfer device 2. The guiding strips 12 can play a guiding role for the transfer device 2. Specifically, the guiding strips 12 are arranged on the outer sides of the two ground rails 11 facing away from each other. Further preferably, the entrance end of the guiding strip 12 is configured as an inclined surface 121 to facilitate guiding the transfer device 2 into the ground rail 11.

[0026] As a preferred technical solution of this embodiment, a first cross beam 13 is arranged between the two ground rails 11, and the two ends of the first cross beam 13 are fixedly connected to the two ground rails 11; a second cross beam 16 is also arranged between the two ground rails 11, and the two ends of the second cross beam 16 are fixedly connected to the two ground rails 11.

[0027] As a preferred technical solution of this embodiment, in order to determine that the transfer device 2 is successfully aligned with the ground rail 11, at least two infrared sensors 14 are assembled on the first cross beam 13. The at least two infrared sensors 14 are arranged in a staggered manner. Correspondingly, a reflection panel 213 corresponding to the infrared sensors 14 is arranged on the transfer device 2.

[0049] As a preferred technical solution of this embodiment, a positioning pin 33111 is arranged on the upper surface of the upper plate member 3311, and a positioning groove 321 is provided at the bottom of the tray 32. At least two positioning pins 33111 can be arranged, and the positioning pins 33111 can be inserted into the positioning groove 321 of the tray 32 to position the position of the tray 32. In this embodiment, two positioning pins 33111 are arranged, and are respectively arranged near a set of diagonals of the upper plate member 3311.

[0050] As a preferred technical solution of this embodiment, at least two support protrusions are further arranged on the upper surface of the upper plate member 3311 to cooperate with the positioning pins 33111 to stably support the tray 32. In this embodiment, two support protrusions are arranged, and are respectively arranged near another set of diagonals of the upper plate member 3311.

[0051] Based on the above structure, for the hydraulic motor assembly conveying line of this embodiment, the workpiece conveyed is a fitting of the hydraulic motor. When the transfer device 2 docks with the conveying module 3, first, the steering assembly 23 is used to adjust the traveling direction of the roller group 22 of the transfer device 2, and the locking structure 24 locks the driving rod 231, so that the transfer device 2 can travel along a direction parallel to the conveying module 3. When the transfer device 2 moves close to the guiding module 1, observe the signal lights 15. When all the signal lights 15 are on, it means that the transfer device 2 is successfully aligned with the guiding module 1.

[0052] Then, unlock the locking structure 24, rotate the handwheel of the steering assembly 23 by 180 degrees. At this time, another locking tongue 241 rotates to the position of the movable lock 242, and the roller group 22 rotates by 90 degrees. Then rotate the movable lock 242 of the locking structure 24, and the movable lock 242 locks the locking tongue 241, and further the position of the driving rod 231 is locked.

[0053] Finally, the transfer device 2 is pushed towards the guiding module 1. The guiding wheel 2213 can move along the guiding strip 12. When the proximity switch 18 senses that the locking rod 214 enters the locking groove 1711 of the locking structure 17, the locking cylinder 172 is triggered to work. The telescopic end of the locking cylinder 172 extends to lock the locking rod 214 in the locking groove 1711, locking the position of the transfer device 2. An accurate docking is achieved between the transfer device 2 and the conveying module 3, and the tray 32 and the workpiece thereon can be conveyed between the transfer device 2 and the conveying module 3.

[0054] When the tray 32 reaches the corresponding station, it will be detected by the detection switch. The detection switch controls the lifter to lift the limiting tray 32, and the driving module 33 drives the positioning module 331 to lift. The tray 32 is positioned through the insertion assembly. After positioning, the driving module 33 continues to lift the tray 32 to reach the assembly area. After assembly, the driving module 33 descends, driving the tray 32 to descend onto the conveying rack 31. The driving module 33 drives the positioning module 331 to continue descending until it disengages from the tray 32. When the driving module 33 returns to the lowest point, the lifter is reset by the photoelectric switch, and all the constraints on the tray 32 are released. The tray 32 continues to move along the conveying rack 31.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
