Description
Technical Field
[0001] The utility model relates to the technical field of stackers, in particular to a stacker used for machine tool processing. Background Art
[0002] At present, stackers are widely used in the automatic warehousing industry and are an important component of material turnover equipment. Traditional stackers are only used to store materials at designated points on shelves and take materials from shelves and place them at designated points. In this process, there is no great requirement for the placement accuracy of materials, and the docking equipment does not have high positioning accuracy.
[0003] The stacker of the prior art solution has the following technical deficiencies:
[0004] 1. The stacker is driven by a motor to directly drive the walking wheel mechanism on the guide rail to drive the stacker body to move, thereby realizing the horizontal movement of the stacker. However, the movement accuracy is not high. During machine tool processing, it cannot meet the high requirements for the positioning accuracy and operation stability of the stacker in the horizontal direction.
[0005] 2. The lifting mechanism of the stacker uses a steel wire rope and a drum to drive the cage up and down to realize the up and down transfer of materials on the stacker. However, the up and down movement of the cage is supported by a guide wheel and a column. This kind of stability is not high, and it cannot meet the requirements of the positioning accuracy and movement stability of the cage, and cannot meet the requirements of the accuracy of placing and taking materials during machine tool processing. Utility Model Content
[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a stacker for machine tool processing with high operating accuracy and high stability.
[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions: a stacker used for machine tool processing, including a walking mechanism, the walking mechanism including a guide rail, a rack arranged along the axial direction of the guide rail is provided on the side of the guide rail, a mounting seat is slidably provided on the guide rail, the mounting seat is connected to the stacker body, a rotating seat is hinged on the mounting seat, a tensioning mechanism is also provided on the mounting seat for tensioning connection with the rotating seat, a driving member is provided on the rotating seat, and the driving end of the driving member is meshed with a gear and a rack to drive the mounting seat to move along the guide rail.
[0008] As a further improvement of the above technical solution:
[0009] A vertical guide rod is provided on the mounting seat, and the rotating seat connection sleeve is arranged on a sleeve outside the guide rod. The tensioning mechanism includes a tensioning screw rod which is transversely passed through the mounting seat, one end of the tensioning screw rod is connected to the rotating seat, and the other end of the tensioning screw rod which extends out of the mounting seat is wound with an elastic member which abuts against the mounting seat.
[0010] The rotating seat is provided with a reducer, and the driving end of the driving member is connected with a gear through the reducer.
[0011] The driving member is a servo motor, and the reducer is a planetary reducer.
[0012] A transverse limiting screw is also provided on the mounting seat near the tensioning mechanism. The protruding end of the limiting screw movably passes through the rotating seat and is connected to the limiting nut head to prevent the rotating seat from being separated from the mounting seat when the tensioning mechanism fails.
[0013] Limiting pieces are arranged at both ends of the guide rail to form buffering limits for the walking mechanism.
[0014] A vertical guide mechanism matched with the column is also provided, and the vertical guide mechanism is installed on the cargo cage.

[0029] like Figures 1 to 6 As shown, the stacker for machine tool processing of this embodiment includes a traveling mechanism 1, which includes a guide rail 11, a rack 12 arranged axially along the guide rail 11 is provided on the side of the guide rail 11, a mounting seat 13 is slidably provided on the guide rail 11, the mounting seat 13 is connected to the stacker body, a rotating seat 14 is hinged on the mounting seat 13, a tensioning mechanism is also provided on the mounting seat 13 for tensioning connection with the rotating seat 14, a driving member 18 is provided on the rotating seat 14, and a driving end of the driving member 18 is meshed with the rack 12 through a gear 15 to drive the mounting seat 13 to move along the guide rail 11. The specific implementation principle is as follows:
[0030] The stacker is used for high-precision stacking in machine tool processing. When in use, the stacker is driven by the walking mechanism 1 to move horizontally on the guide rail 11. The mounting seat 13 sliding on the guide rail 11 is provided with a gear 15, and the gear 15 is meshed with the rack 12 on the side of the guide rail 11. The driving member 18 drives the gear 15 to move, converting the circular motion of the gear 15 into a linear feed motion of the gear 15 on the rack 12, driving the stacker to move on the guide rail 11 as a whole. The use of the gear 15 and the rack 12 as the transmission structure can improve the operation accuracy of the stacker. More importantly, the gear 15 is set on the rotating seat 14 that can be tensioned and rotated on the mounting seat 13, so that the gear 15 can be tensioned and rotated. By adjusting the angle of the gear 15, the gear 15 is always meshed with the rack 12 on the side of the guide rail 11, thereby improving the stability of the stacker's operation. It is also suitable for the case of non-linear guide rails 11, thereby improving the applicability of the stacker.
[0031] Preferably, the traveling mechanism 1 further comprises traveling wheels (not shown in the figure), which are arranged between the stacker body and the guide rails, and the traveling wheels are used to reduce the resistance between the stacker and the guide rails 11 and improve the smoothness of the stacker moving on the guide rails 11.
[0032] In this embodiment, a vertical guide rod 131 is provided on the mounting seat 13, and the rotating seat 14 is connected to the sleeve 132 outside the guide rod 131. The tensioning mechanism includes a tensioning screw 16 that is transversely inserted into the mounting seat 13. One end of the tensioning screw 16 is connected to the rotating seat 14, and the other end of the tensioning screw 16 that extends out of the mounting seat 13 is wound with an elastic member 17 (such as a spring, rubber, etc.) that abuts against the mounting seat 13. When the tensioning screw 16 presses the elastic member 17, the elastic member 17 generates a force, so that the rotating seat 14 rotates around the guide rod 131 on the mounting seat 13 under the drive of the sleeve 132, until the gear 15 connected to the rotating seat 14 and the rack 12 are matched without clearance to generate thrust and reach a balanced state. By setting the tensioning screw 16, the gear 15 and the rack 12 can automatically achieve a gapless fit, avoiding the gap between the gear 15 and the rack 12, causing the stacker to stop moving, and preventing noise from being generated by multiple starts and stops.
[0033] In this embodiment, a reducer 19 is provided on the rotating seat 14, and the driving end of the driving member 18 is connected to the gear 15 through the reducer 19. By providing the reducer 19, the gear 15 is further provided with more precise walking accuracy, and the positioning accuracy of the stacker in the horizontal direction is further improved.
[0034] In this embodiment, the driving member 18 is a servo motor and the reducer 19 is a planetary reducer. The servo motor has high control accuracy and the planetary reducer has high transmission efficiency and strong stability, which further improves the horizontal positioning accuracy of the stacker and can ensure that the horizontal positioning accuracy of the stacker is ≤±1.5mm.
[0035] In this embodiment, a transverse limiting screw 133 is further provided on the mounting seat 13 near the tensioning mechanism, and the extended end of the limiting screw 133 is movably passed through the rotating seat 14 and connected to the limiting nut head, so as to prevent the rotating seat 14 from being separated from the mounting seat 13 when the tensioning mechanism fails. The limiting screw 133 plays a protective role when the traveling mechanism 1 is running, preventing the tensioning screw 16 from failing when the stacker moves at high speed, causing the gear 15 and the rack 12 to be disengaged, and the stacker derailing and rushing out after losing power, thereby improving the safety and reliability of the stacker.
[0036] In this embodiment, limit members 7 are provided at both ends of the guide rail 11 to form a buffer limit for the walking mechanism 1. The limit members 7 further prevent the stacker from rushing out of the two sides of the guide rail 11 and derailing. Preferably, a buffer member (such as a spring, rubber, etc.) is connected to one end of the limit member 7 close to the stacker body. When the stacker moves to the limit member 7, the buffer member provides a buffering force to prevent excessive impact force from damaging the stacker body.
[0037] In this embodiment, a vertical guide mechanism 3 is also provided to cooperate with the column 5. The vertical guide mechanism 3 is installed on the cargo cage 4 to prevent the cargo cage 4 from deflecting during the up and down movement, thereby preventing damage to the cargo. The vertical guide mechanism 3 includes a swing arm 31, and guide wheels 32 are connected to both ends of the swing arm 31. The guide wheels 32 abut against the column 5. The guide wheels 32 are connected to both ends of the swing arm 31 to play a guiding role, so that when the guide center span of the cargo cage 4 of the same size does not change much, the cargo cage 4 has a heavier load-bearing capacity, improves the stability of the movement of the cargo cage 4, and improves the movement accuracy of the cargo cage 4. In addition, the guide wheels 32 are connected to both ends of the swing arm 31, and the structure is simple and compact. Compared with the traditional guide wheel group for guidance, it is convenient to install and debug, and there is no need to increase the height of the stacker due to the increase in the guide center distance.
[0038] Preferably, a plurality of vertical guide mechanisms 3 can be provided according to the size of the cargo cage 4 to further improve the stability of the movement of the cargo cage 4 .
[0039] In this embodiment, the middle part of the swing arm 31 is swingably connected to the bottom plate 34 through the rotating shaft 33. The bottom plate 34 is fixedly connected to the cargo cage 4, and the guide wheel 32 on the swing arm 31 always abuts against the column 5. The guide wheel 32 slides on the column 5 to guide the movement of the cargo cage 4. By adjusting the angle between the swing arm 31 and the bottom plate 34, the guide wheel 32 on the swing arm 31 always abuts against the column 5, further improving the stability of the movement of the cargo cage 4.
[0040] In this embodiment, a ceiling rail guide mechanism 6 is also included on the top of the stacker to further improve the stability of the stacker body when it moves on the guide rail 11.
[0041] In this embodiment, the traveling mechanism 1 further comprises a guide plate 2 arranged on the guide rail 11. The guide plate 2 plays a guiding role, and the guide plate 2 is arranged on the guide rail 11 to further improve the stability of the stacker running on the guide rail 11.
