Description

Technical Field

[0001] This utility model relates to the field of workbench technology, and in particular to a workbench roller mounting and positioning device. Background Technology

[0002] In industries such as machinery manufacturing and logistics warehousing, workbenches serve as crucial work surfaces and often require casters for easy movement. However, existing workbench caster installation methods present several problems. Traditional methods rely heavily on manual measurement and fixing, making it difficult to guarantee installation accuracy. This can lead to caster misalignment, causing the workbench to drift or wobble during movement, affecting stability and safety. Furthermore, manual installation is inefficient, requiring significant time and manpower, thus increasing production costs.

[0003] Some existing auxiliary installation tools are complex in structure, cumbersome in operation, require high technical skills from operators, and have poor versatility, only applicable to rollers or worktables of specific specifications, failing to meet diverse installation needs. In addition, in the existing installation process, workers need to manually push the positioned rollers to the installation position, which can easily lead to roller displacement during installation, further affecting installation accuracy and efficiency. Therefore, we propose a worktable roller installation and positioning device. Utility Model Content

[0031] In this embodiment, a push handle 5 is fixedly installed on the right side of the movable support platform 3, and multiple pulleys 6 are rotatably installed on the outer side of the movable support platform 3. A workbench roller adjustment displacement assembly 2 is provided above the movable support platform 3, the turntable 7 and the connecting frame 8.

[0032] In this embodiment, the workbench roller clamping and pushing assembly 1 further includes a one-way lead screw 17, a first transmission gear 18, a moving plate 19, and a pushing plate 20. The one-way lead screw 17 is rotatably mounted on the upper and lower sides of the roller fixing box 4. The first transmission gear 18 is fixedly mounted on the outside of the one-way lead screw 17 and the auxiliary shaft 15. Adjacent first transmission gears 18 mesh with each other.

The adjustment arm 21 is rotatably mounted on the inner side of the connecting frame 8, and the movable connecting arm 22 is rotatably mounted on the inner side of the adjustment arm 21.

[0034] In this embodiment, the worktable roller adjustment displacement assembly 2 further includes a second motor 23, a drive shaft 24, a second transmission gear 25, and a toothed groove 26. The second motor 23 is fixedly installed on the inner side of the movable support platform 3, the drive shaft 24 is fixedly installed on the output end of the second motor 23, the second transmission gear 25 is fixedly installed on the outer side of the drive shaft 24, and the toothed groove 26 is opened on the outer side of the turntable 7. The second transmission gear 25 and the toothed groove 26 mesh with each other. The second transmission gear 25 can drive the turntable 7 to rotate through the toothed groove 26. After the turntable 7 rotates, it can adjust the position and angle of the connecting frame 8, the adjusting arm 21, and the movable connecting arm 22, so as to achieve high working efficiency.

[0035] In this embodiment, a driving component is fixedly installed on one side of the connecting frame 8 and the adjusting arm 21. The adjusting arm 21 and the movable connecting arm 22 are fixedly installed on the output shaft of the driving component. The driving component is a stepper motor.

The second motor 23 is controlled to drive the drive shaft 24 and the second transmission gear 25 to rotate. The second transmission gear 25 can drive the turntable 7 to rotate through the tooth groove 26, so as to facilitate the adjustment of the angle of the adjusting arm 21, the movable connecting arm 22 and the roller fixing box 4. A driving component is provided above the connecting frame 8 and the adjusting arm 21, which can drive the adjusting arm 21 and the movable connecting arm 22. The device is adjusted and oscillated so that the movable connecting arm 22 can drive the clamped roller to perform positioning and adjustment, resulting in high work efficiency and high positioning accuracy. After positioning, the roller is aligned with the installation position. At this time, the first motor 11 can be controlled to drive the bidirectional lead screw 12 to rotate in the opposite direction. The bidirectional lead screw 12 can drive the auxiliary shaft 15 to rotate through the bevel gear 16. After the auxiliary shaft 15 rotates, it can drive the one-way lead screws 17 on both sides to rotate through the first transmission gear 18. After the one-way lead screws 17 rotate, they can drive the moving plate 19 and the push plate 20 to move through the threaded engagement. The push plate 20 can push the roller into the installation position. After the sliding plate 13 and the moving clamping plate 14 move in the opposite direction, they can release the clamping of the roller, so that the device does not require manual operation by the operator.
