Description
Technical Field
[0001] This utility model relates to the field of machining technology, and in particular to an automatic handling device for workpiece processing. Background Technology
[0002] In machining production lines, small and medium-sized workpieces such as shafts and discs need to be frequently transferred. However, the industry currently mostly uses manual handling or simple trolley handling: manual handling requires workers to directly lift or move the workpieces, which is limited by physical strength, resulting in small amounts of workpieces being moved at a time and slow speed. Moreover, since the surfaces of the workpieces are mostly metal, they are prone to slipping and falling, causing damage and potentially injuring workers. While simple trolley handling can carry more workpieces, it requires manual pushing for positioning and is difficult to accurately stop next to narrow machining stations. Loading and unloading workpieces still requires manual assistance, making the overall process cumbersome and unable to meet the demands of modern production lines for efficient and safe handling. Therefore, we have introduced an automated workpiece handling device. Utility Model Content
[0003] The main objective of this invention is to provide an automatic handling device for workpiece processing, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic handling device for workpiece processing includes a base, with locking casters fixedly installed at the four corners of the lower end of the base, a Z-axis adjustment mechanism fixedly installed on the upper left side of the base, an X-axis adjustment mechanism fixedly installed on the upper rear side of the base, a Y-axis adjustment mechanism fixedly installed on the upper end of the X-axis adjustment mechanism, and a control panel fixedly installed on the front end of the base.
[0005] Preferably, the Y-axis adjustment mechanism includes a third servo motor and a third mounting box. The output end of the third servo motor passes through the rear end of the third mounting box and extends into the third mounting box. A third reducer is fixedly installed at the output end of the third servo motor. A third lead screw is fixedly installed on the output shaft of the third reducer. A third lead screw nut is threaded onto the outer surface of the third lead screw. A clamping assembly is fixedly installed at the front end of the third lead screw nut. A third guide groove with internal and external through-holes is opened at the front end of the third mounting box.
[0006] By adopting the above technical solution: the third servo motor provides power, which is reduced by the third reducer and drives the third lead screw to rotate, so that the third lead screw nut moves along the third lead screw, thereby driving the clamping assembly to stably adjust its up and down position along the third guide groove of the third mounting box. This can accurately control the clamping assembly to move closer to or further away from the workpiece, ensuring the accuracy of the handling and positioning.
[0007] Preferably, the clamping assembly includes a fixed box, a cylinder is fixedly installed on the lower inner wall of the fixed box, and the output end of the cylinder passes through the lower inner wall of the fixed box and extends to the outside of the fixed box. A control plate is fixedly installed on the output end of the cylinder. Connecting blocks are fixedly connected to the left and right ends of the fixed box. V-shaped clamping plates are movably installed on the two connecting blocks via a rotating shaft. Control rods are movably installed in the middle of the two V-shaped clamping plates via a rotating shaft. The ends of the two control rods that are close to each other are movably connected to the left and right ends of the control plate via rotating shafts, respectively.

The rear end of the fixed box is fixedly connected to the front end of the third lead screw nut.
[0008] By adopting the above technical solution: after the cylinder is started, its output end drives the control board to move. The control board pulls the two V-shaped clamping plates to rotate around the connecting block through the control rod, so that the two clamping heads come closer to each other and clamp the workpiece. The anti-slip groove of the clamping head can increase the friction with the workpiece and prevent the workpiece from slipping.
[0009] Preferably, the Z-axis adjustment mechanism includes a first servo motor and a first mounting box. The output end of the first servo motor passes through the right end of the first mounting box and extends into the first mounting box. A first reducer is fixedly installed at the output end of the first servo motor. A first lead screw is fixedly installed on the output shaft of the first reducer. A first lead screw nut is threaded onto the outer surface of the first lead screw. A storage seat is fixedly connected to the upper end of the first lead screw nut. The upper surface of the storage seat is provided with anti-slip texture. A first guide groove with internal and external through-holes is opened at the upper end of the first mounting box. The lower ends of the first servo motor and the lower ends of the first mounting box are both fixedly connected to the upper end of the base.
[0010] By adopting the above technical solution: the first servo motor drives the first lead screw to rotate after being reduced by the first reducer, and the first lead screw nut moves along the first lead screw and drives the placement seat to adjust its front and rear position along the first guide groove of the first mounting box, which can adjust the workpiece to a suitable clamping position and improve the efficiency of pre-handling preparation.
[0011] Preferably, the first reducer is fixedly installed inside the first reducer, the rear end of the first lead screw is movably connected to the rear inner wall of the first mounting box through a rotating shaft, and the upper part of the first lead screw nut is movably sleeved in the first guide groove.
[0012] By adopting the above technical solution: the rear end of the first lead screw is movably connected to the inner wall of the first mounting box through a rotating shaft, ensuring smooth rotation of the first lead screw; the upper part of the first lead screw nut is movably sleeved in the first guide groove, which can restrict the rotation of the first lead screw nut, so that it only moves back and forth along the first guide groove, thereby improving the stability of the Z-axis adjustment mechanism position adjustment.
[0013] Preferably, the X-axis adjustment mechanism includes a second servo motor, a second mounting box, and a connecting plate. The output end of the second servo motor passes through the front end of the second mounting box and extends into the second mounting box. A second reducer is fixedly installed at the output end of the second servo motor. A second lead screw is fixedly installed on the output shaft of the second reducer. A second lead screw nut is threaded onto the outer surface of the second lead screw. A fixing plate is fixedly connected to the upper end of the second lead screw nut. A T-shaped stabilizing plate is fixedly connected to the rear lower end of the fixing plate. A second guide groove with internal and external through-holes is opened at the upper end of the second mounting box. A T-shaped guide groove is opened at the upper end of the connecting plate. The lower ends of the second servo motor and the lower ends of the second mounting box are both fixedly connected to the upper end of the base. The front end of the connecting plate is fixedly connected to the rear end of the base.
[0014] By adopting the above technical solution: the second servo motor drives the second lead screw to rotate after being reduced by the second reducer, and the second lead screw nut moves along the second lead screw and drives the fixing plate to adjust its left and right position along the second guide groove of the second mounting box.
[0015] Preferably, the second reducer is fixedly installed in the second mounting box, the left end of the second lead screw is movably connected to the left inner wall of the second mounting box through a rotating shaft, the upper part of the second lead screw nut is movably sleeved in the second guide groove, and the lower part of the T-shaped stabilizing plate is movably sleeved in the T-shaped guide groove.
[0016] By adopting the above technical solution: the left end of the second lead screw is movably connected to the left inner wall of the second mounting box through a rotating shaft, ensuring smooth rotation of the second lead screw. The upper part of the second lead screw nut is sleeved in the second guide groove, and the lower part of the T-shaped stabilizing plate is sleeved in the T-shaped guide groove. The double limit further restricts the movement direction of the fixed plate, avoids deviation, greatly improves the stability of the X-axis adjustment mechanism movement, and ensures the reliability of the overall handling process.
[0017] Preferably, the lower end of the third servo motor and the lower end of the third mounting box are both fixedly connected to the upper end of the fixing plate, the third reducer is fixedly installed in the third mounting box, the upper end of the third lead screw is movably connected to the upper inner wall of the third mounting box through a rotating shaft, and the front part of the third lead screw nut is movably sleeved in the third guide groove.
[0018] By adopting the above technical solution: the upper end of the third lead screw is movably connected to the inner wall of the third mounting box through a rotating shaft, ensuring smooth rotation of the third lead screw. The front part of the third lead screw nut is sleeved in the third guide groove, restricting its movement to only up and down. This makes the position adjustment of the clamping component more accurate and stable when the Y-axis adjustment mechanism and the X-axis adjustment mechanism work together, thereby improving the overall level of automation in handling.
[0019] Compared with the prior art, the present invention has the following beneficial effects: In use, the workpiece to be transported is placed on the seat of the Z-axis adjustment mechanism. The first servo motor is started via the control panel at the front of the base, which drives the first lead screw to rotate via the first reducer. The first lead screw nut moves the seat along the first guide groove to adjust its position. Then, the second servo motor of the X-axis adjustment mechanism is started, which drives the second lead screw to rotate via the second reducer. The second lead screw nut moves the fixing plate along the second guide groove to adjust the position of the Y-axis adjustment mechanism. Subsequently, the third servo motor is started, which drives the third lead screw to rotate via the third reducer. The third lead screw nut moves the clamping assembly along the third guide groove to approach the workpiece. The cylinder is then activated to push the control board, which drives the V-shaped clamping plate and clamping head to clamp the workpiece via the control rod. The first, second, and third servo motors are then started in reverse to transport the workpiece to the target position and then release the workpiece, thus achieving automated transport and improving efficiency and safety.
