Description

Technical Field

[0001] The utility model relates to the technical field of electromechanics, in particular to a grabbing device for a mechatronic lathe. Background Art

[0002] Mechatronics, also known as mechatronics, is a type of mechanical engineering and automation. Mechatronic lathes can automatically process products. Previously, loading materials onto lathes was done manually, which was dangerous and required a lot of manpower, increasing labor costs. Furthermore, manual loading was extremely slow, slowing down the workpiece forming process and, consequently, the production of parts. To facilitate this, gripping devices have been designed.

[0003] A search of the announcement number CN 215431546 U reveals a gripping device for a mechatronic lathe, comprising a fixed base plate and a gripping mechanism, a rotating shaft, a connecting slider, a fixed frame, and a first threaded rod disposed on one side of the fixed base plate. The top of the fixed base plate is rotatably connected to the rotating shaft, and the top of the rotating shaft is fixedly connected to the first fixed rod. To improve gripping efficiency, a hydraulic push rod drives the second fixed rod fixed to the bottom to move downward. The second fixed rod drives the third rotating rod to rotate inward via the second rotating rod. Simultaneously, the third rotating rod drives the half gear fixed to it to rotate. The half gear drives the meshed rack to slide on both sides on the third fixed rod. Simultaneously, the other side of the rack drives the gripper fixed to it to slide on both sides on the mounting shell. At this time, the two grippers open, resetting the hydraulic push rod. The rack drives the gripper to reset and grip the object to be gripped, greatly improving gripping efficiency.

[0004] However, the above-mentioned gripping device still has some shortcomings during use. The workpiece is gripped by the squeezing force exerted by the grippers on both sides. When the grippers on both sides clamp and move the workpiece, there is a lack of protection under the workpiece, which causes the workpiece to shake and fall easily during movement, making it inconvenient to use. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a gripping device for a mechatronic lathe, which solves the problem of gripping the workpiece by the extrusion force exerted by the grippers on both sides. When the grippers on both sides clamp and move the workpiece, there is a lack of protection under the workpiece, which causes the workpiece to shake and fall easily during movement, making it inconvenient to use.

[0006] The utility model provides the following technical solution: a gripping device for a mechatronic lathe, comprising a connecting plate, the interior of the connecting plate being hollow and having two movable grooves on the lower surface, a bidirectional screw rod being rotatably connected between the inner side walls of the connecting plate, the surface of the bidirectional screw rod being threadedly sleeved with two screw rod sleeves, the lower ends of the two screw rod sleeves extending to the outside of the connecting plate and being fixedly connected to the mounting plate, the lower surfaces of the two mounting plates being fixedly connected to the mounting frames, the inner top walls and bottom walls of the two mounting frames being rotatably connected with threaded rods, the surfaces of the two threaded rods being threadedly sleeved with threaded sleeves, one side surface of the two threaded sleeves being fixedly connected to the splint, one side surface of the two mounting frames being fixedly connected to the cross plate, the lower surfaces of the two cross plates being rotatably connected to a group of rotating rods, and the bottom end of each rotating rod being fixedly connected to a baffle.

[0007] Preferred technical solution one: a sliding rod is rotatably connected between the internal top wall and bottom wall of each installation frame, a sliding sleeve is slidably sleeved on the surface of each sliding rod, each sliding sleeve is fixedly connected to the corresponding clamping plate, and a first motor is fixedly connected to the upper surface of each installation frame, and the output end of each first motor passes through the connected installation frame and is fixedly connected to the corresponding threaded rod.

[0008] This solution can drive the clamping plate to rise and fall under the restriction of the sliding rod and the sliding sleeve through the rotation of the first motor, which is convenient for driving the workpiece to rise and fall.

[0009] Preferred technical solution two: Each of the horizontal plates is fixedly connected to two short plates, each of the sliding sleeves and one side of each threaded sleeve is fixedly connected to a vertical rod, the surface of each vertical rod is fixedly connected to a row of racks, one side of each short plate is rotatably connected to a worm, the top of each rotating rod extends to the top of the connected horizontal plate and is fixedly sleeved with a worm wheel, each of the worm wheels is respectively meshed with the corresponding worm, one end of each worm is fixedly sleeved with a gear, and each gear is respectively meshed with the corresponding rack.

[0010] This solution can drive the baffle to rotate to the bottom of the workpiece through the upward movement of the threaded sleeve and the sliding sleeve to protect it and avoid accidental falling.

[0011] Preferred technical solution three: A limiting rod is fixedly connected between the inner two side walls of the connecting plate, and two limiting sleeves are slidably sleeved on the surface of the limiting rod. The bottom ends of the two limiting sleeves are respectively fixedly connected to the two mounting plates, and the two limiting sleeves and the two limiting sleeves can move respectively inside the two movable grooves.

[0012] This solution limits the movement of the screw sleeve, the mounting plate and the mounting frame through the limit sleeve, making it easier to clamp and fix the workpiece.

[0013] Preferred technical solution four: A second motor is fixedly mounted on one side of the connecting plate, and an output end of the second motor extends to the interior of the connecting plate and is fixedly connected to the bidirectional screw rod.

[0014] In this solution, the rotation of the second motor can drive the two clamping plates to stably clamp the workpiece.

[0015] Preferred technical solution five: rubber pads are fixedly adhered to the surfaces of the two clamping plates, and the surface of each rubber pad is provided with anti-slip grooves.

[0016] This solution can facilitate better clamping of the workpiece and avoid accidental dropping.

[0017] Compared with the prior art, the utility model provides a gripping device for a mechatronic lathe, which has the following beneficial effects: when in use, the rotation of the second motor drives the bidirectional screw to rotate, thereby driving the two screw sleeves and the mounting plate to move toward each other, thereby driving the two mounting frames and the clamping plate to move toward each other to clamp and fix the workpiece. When the workpiece is clamped, the threaded rod is driven to rotate by controlling the rotation of the first motor, thereby driving the threaded sleeve, the limit sleeve and the clamping plate to move upward to drive the workpiece to rise. At the same time, the threaded sleeve and the limit sleeve drive the vertical rod to move upward, and the gear is driven to rotate through the action of the rack, thereby driving the corresponding worm to rotate, thereby driving the worm wheel to rotate, which can drive the rotating rod and the baffle to rotate, so that the two sets of baffles are rotated to the bottom of the workpiece to protect the workpiece, avoiding the workpiece from accidentally falling during the gripping movement, and is convenient to use.

[0024] Embodiment 2: The difference between this embodiment and embodiment 1 is that, a sliding rod 20 is rotatably connected between the internal top wall and the bottom wall of each mounting frame 6, a sliding sleeve 21 is slidably sleeved on the surface of each sliding rod 20, each sliding sleeve 21 is fixedly connected to the corresponding clamping plate 9, and a first motor 22 is fixedly connected to the upper surface of each mounting frame 6. The output end of each first motor 22 passes through the connected mounting frame 6 and is fixedly connected to the corresponding threaded rod 7. The rotation of the first motor 22 drives the clamping plate 9 to rise and fall under the restriction of the sliding rod 20 and the sliding sleeve 21, so as to facilitate driving the workpiece to rise and fall.

[0025] Embodiment 3: The difference between this embodiment and embodiment 1 is that, each horizontal plate 10 is fixedly connected to two short plates 16, each sleeve 21 and one side of each threaded sleeve 8 are fixedly connected to a vertical rod 14, the surface of each vertical rod 14 is fixedly connected to a row of racks 15, and one side of each short plate 16 is rotatably connected to a worm 17. The top of each rotating rod 11 extends to the top of the connected horizontal plate 10 and is fixedly sleeved with a worm gear 18, and each worm gear 18 is respectively meshed with the corresponding worm 17, and one end of each worm 17 is fixedly sleeved with a gear 19, and each gear 19 is respectively meshed with the corresponding rack 15. The upward movement of the threaded sleeve 8 and the sleeve 21 drives the baffle 12 to rotate to the bottom of the workpiece to protect it and avoid accidental falling.

[0026] Example 4: The difference between this example and Example 1 is that a limiting rod 23 is fixedly connected between the inner two side walls of the connecting plate 1, and two limiting sleeves 24 are slidably sleeved on the surface of the limiting rod 23. The bottom ends of the two limiting sleeves 24 are respectively fixedly connected to the two mounting plates 5. The two limiting sleeves 24 and the two limiting sleeves 24 can move respectively inside the two movable grooves 2.

[0029] To sum up, when the mechatronic lathe grasping device is in use, the rotation of the second motor 13 drives the bidirectional screw 3 to rotate, thereby driving the two screw sleeves 4 and the mounting plate 5 to move toward each other, thereby driving the two mounting frames 6 and the clamping plate 9 to move toward each other to clamp and fix the workpiece. When the workpiece is clamped, the rotation of the first motor 22 is controlled to drive the threaded rod 7 to rotate, thereby driving the threaded sleeve 8, the limit sleeve 24 and the clamping plate 9 to move upward to drive the workpiece to rise. At the same time, the threaded sleeve 8 and the limit sleeve 24 drive the vertical rod 14 to move upward, and the gear 19 is driven to rotate by the action of the rack 15, thereby driving the corresponding worm 17 to rotate, thereby driving the worm wheel 18 to rotate, which can drive the rotating rod 11 and the baffle 12 to rotate, so that the two sets of baffles 12 are rotated to the bottom of the workpiece to protect the workpiece, thereby preventing the workpiece from accidentally falling during the grasping movement, which is convenient to use.
