Technical Field
[0001] This utility model relates to the field of logistics and warehousing equipment technology, specifically to a positioning gripper with a steering adjustment function. Background Technology
[0002] Material grippers are key equipment in logistics and warehousing automation. Positioning grippers can quickly and accurately grab and move goods, significantly shortening operation time and improving warehousing efficiency. Through automated operation, positioning grippers can also reduce labor costs and reduce the risk of goods damage and loss due to human error.
[0003] For example, the utility model patent disclosed in publication number CN215661797U discloses a positioning gripper, comprising: a mounting base and a piston rod retractably mounted in the mounting base, with a limit pin vertically connected to the piston rod; a first gripper and a second gripper pivotally connected via a rotating shaft, the rotating shaft being parallel to the limit pin and passing through the end of the piston rod; the first gripper having a first limiting groove cooperating with the limit pin on the side facing the mounting base, and the second gripper having a second limiting groove cooperating with the limit pin on the side facing the mounting base; a first connecting rod and a second connecting rod, one end of the first connecting rod being rotatably mounted on the mounting base and the other end being rotatably connected to the first gripper, and one end of the second connecting rod being rotatably mounted on the mounting base and the other end being rotatably connected to the second gripper. In this application, the limit pin is in direct contact with the first and second grippers, and the braking force is directly applied to the first and second grippers, resulting in strong clamping stability.
[0004] Although the aforementioned grippers can clamp materials, they are not convenient for adjusting the radial angle before clamping the materials as needed. Furthermore, the grippers are not suitable for adaptively clamping materials that are tilted laterally, thus reducing their practical performance. Therefore, there is an urgent need for positioning grippers with steering adjustment functions to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6One embodiment of this utility model provides a positioning gripper with a steering adjustment function, including an adjustment device 4, wherein a linear slider 5 for guidance is symmetrically arranged on the side end face of the adjustment device 4.
[0025] The transmission screw 7 is threaded to the lower end face of the adjustment device 4. A fixed slide 3 is provided at the bottom of the transmission screw 7, and a linear slide shaft 6 is symmetrically provided at the upper end face of the fixed slide 3. A servo motor 8 is provided on the side of the upper end face of the fixed slide 3, and a drive gear 1 is provided at the output end of the servo motor 8.
[0026] The clamping device 2 is rotatably engaged with the bottom of the inner end face of the fixed slide 3, and the clamping device 2 is meshed with the drive gear 1. The clamping device 2 is used for positioning and clamping.
[0027] The clamping device 2 includes a driven gear 21, a fixed seat 22 is provided at the center of the lower end face of the driven gear 21, and a long-stroke electric cylinder chuck 23 is fixedly provided on the inner end face of the fixed seat 22. Two sets of limiting clamps 24 are provided at the bottom of the long-stroke electric cylinder chuck 23.
[0028] The adjusting device 4 includes a positioning guide 41, a flipping guide 47 rotatably engaged on the inner end face of the positioning guide 41, a first gear 42 rotatably engaged at the center of the inner end face of the flipping guide 47, and a threaded sleeve 43 fixedly disposed at the center of the inner end face of the first gear 42. A stepper motor 49 is disposed near the side of the upper end face of the flipping guide 47, and a second gear 48 is disposed at the output end of the stepper motor 49. A worm gear 44 is disposed at the center of the side end face of the flipping guide 47, and a reduction motor 46 is disposed near the side of the lower end face of the flipping guide 47. A worm 45 is disposed at the output end of the reduction motor 46.
[0029] The driving gear 1 meshes with the driven gear 21, and the worm 45 meshes with the worm wheel 44. When adjusting the radial angle of the two sets of limiting clamps 24, the driving gear 1 can adjust the clamping angle of the limiting clamps 24 on the material in the radial direction by meshing with the driven gear 21.
[0030] The second gear 48 meshes with the first gear 42. The first gear 42 is then threadedly connected to the transmission screw 7 via the threaded sleeve 43. When clamping materials of different heights, the second gear 48 can drive the first gear 42 to rotate via the threaded sleeve 43, thereby facilitating the adjustment of the clamping height of the two sets of limit clamps 24 by the threaded connection between the first gear 42 and the transmission screw 7.
[0031] The worm 45 drives the flipping guide 47 to rotate inside the positioning guide 41 via the worm wheel 44. When the lateral angle of the positioning guide 41 is adjusted, the worm 45 can precisely and stably adjust the two sets of limiting clamps 24 by meshing with the worm wheel 44, which facilitates the subsequent clamping and limiting of materials at different angles.
[0032] Working Principle: Before use, the user can position the equipment onto the slide rail of the external lead screw module or synchronous belt module for traction via the linear slider 5, facilitating subsequent clamping and transfer positioning. During clamping operations, the operator can pre-adjust according to the material being clamped. If it is necessary to adjust the lateral angle of the two sets of limiting clamps 24, the operator can start the reduction motor 46. The reduction motor 46 drives the worm wheel 44 to mesh and rotate through the worm 45, so that the worm wheel 44 can drive the flip guide 47 to rotate precisely laterally inside the positioning guide 41, thereby adjusting the lateral clamping angle of the two sets of limiting clamps 24. The radial clamping angle of the limiting clamp 24 can be adjusted by starting the servo motor 8. At this time, the servo motor 8 can drive the bottom drive gear 1 to rotate. At the same time, the drive gear 1 can drive the side driven gear 21 to rotate. The driven gear 21 can drive the fixed bracket 22 to rotate, thereby quickly adjusting the radial clamping angle of the two sets of limiting clamps 24. When clamping materials, the stepper motor 49 can drive the second gear 48 to rotate. The second gear 48 can drive the threaded rotating sleeve 43 to rotate through the first gear 42, so that the threaded rotating sleeve 43 can be threadedly connected to the transmission screw 7, thereby adjusting the clamping height of the two sets of limiting clamps 24.
