Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a loading and unloading robot. Background Art

[0002] In some mechanical processing, mechanical equipment is usually required to assist in loading and unloading due to the heavy weight of the parts to be processed. A Chinese utility model patent with announcement number CN211250063U discloses a manipulator and device for loading and unloading shaft parts. The automatic lifting and opening and closing of the manipulator are realized by the lifting cylinder and the clamping claw cylinder. The hooks of the clamping fingers are interactively set on the extension arm, and a distance adjustment structure is provided, so that the clamping claw can be adjusted according to the length size of different product parts, and the scope of application is wider. In the above structure, the clamping fingers extend to the left and right ends of the workpiece to clamp it. Some column or shaft parts are solid at both ends and have no holes for extension, so they cannot be effectively clamped and loaded and unloaded. For this reason, we designed a loading and unloading robot. Utility Model Content

[0003] In order to solve the technical problem that it is inconvenient to clamp solid column or shaft parts, the utility model provides a loading and unloading robot.

[0004] The utility model is implemented by the following technical scheme: a loading and unloading robot, comprising two vertically arranged columns, a lateral moving module is installed between the top ends of the two columns, a lifting cylinder is installed on the two sliding blocks on the lateral moving module respectively through an L-shaped bracket, a lifting plate is installed between the bottom ends of the push rods of the two lifting cylinders, two sliding frames are slidably installed on the lifting plate, a clamping assembly is arranged in the sliding frame, and a clamping frame is installed below the clamping assembly.

[0005] As a further improvement of the above scheme, the clamping assembly includes two movable racks arranged inside the sliding frame for moving forward and backward, and two groups of symmetrically distributed movable gears are rotatably installed inside the sliding frame through bearings and shaft rods, the movable gears are meshed with the movable racks for transmission, and a connecting gear is fixed on the front side of the movable gear, a clamping cylinder is installed on the top of the sliding frame, a push rod of the clamping cylinder extends into the sliding frame and is connected to a pushing rack, two groups of pushing racks are provided and are slid up and down in the sliding frame, the two groups of pushing racks are respectively meshed with the connecting gears on both sides, the extension and retraction of the push rod of the clamping cylinder can make the pushing rack move up and down, and then can make the connecting gear rotate, and the moving gear will rotate therewith, so that the moving rack can move inward or outward, thereby changing the distance between the two clamping frames, and thus can fix the workpiece between the two clamping frames.

[0006] As a further improvement of the above scheme, a limiting block is arranged on the rear side of the movable rack, and the sliding frame includes two T-shaped plates, which are connected by a plate material, and a limiting groove is provided on the rear T-shaped plate. The limiting block is slidably placed in the limiting groove, which can limit the moving distance of the movable rack and prevent it from detaching from the sliding frame, thereby improving safety.

[0007] As a further improvement of the above scheme, a vertical plate is installed below the movable rack by screws, and a clamping frame is installed on the inward side of the vertical plate by screws. The clamping frame is L-shaped, and the chamfered corners at the upper edge of the inward side of the clamping frame form a contact arc surface. When the clamping frame clamps column-type or shaft-type parts, its lower two sides will be below the outer side of the workpiece and contact it, and the design of the contact arc surface can avoid scratching it.

[0008] As a further improvement of the above scheme, a mounting plate is installed on the front and rear sides of the upper side of each sliding frame by screws, a rectangular opening is formed between the mounting plate and the sliding frame, and a threaded hole is opened above the mounting plate, and the threaded hole is connected to the rectangular opening, so that the sliding frame can be quickly installed above the lifting plate and can be moved as needed.

[0009] As a further improvement of the above scheme, an adjusting slide hole is provided on the lifting plate, and the upper part of the sliding frame is placed above the lifting plate through the adjusting slide hole, and the rectangular opening is designed to slide with the surface of the sliding frame, and a locking bolt is threadedly connected to the threaded hole, and the bottom end of the locking bolt is in close contact with the upper surface of the lifting plate. The sliding frame and the clamping cylinder can be directly placed above the lifting plate through the adjusting slide hole, which is convenient for their installation. The distance between the clamping frames on the left and right sides can also be adjusted according to the actual length of the workpiece, so that it is suitable for workpieces of various different lengths.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model is provided with a clamping assembly in the sliding frame, and clamping frames are provided at both the front and rear ends below the clamping assembly. The clamping frames can clamp and fix the outer surface of the workpiece, and are suitable for workpieces of various diameters, and can clamp hollow pipes or solid shaft parts, and have diversity;

[0012] 2. By sliding the sliding frame left and right above the lifting plate, the distance between the two sliding frames can be adjusted arbitrarily according to needs, so that the clamping frame can fix both ends of the workpiece, making it more stable when loading and unloading.

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0021] Example: Please combine Figure 1-Figure 5 A loading and unloading robot of the present embodiment includes two vertically arranged columns 1, a lateral moving module 2 is installed between the top ends of the two columns 1, a lifting cylinder 3 is installed on the two sliding blocks on the lateral moving module 2 through an L-shaped bracket 21, a lifting plate 4 is installed between the bottom ends of the push rods of the two lifting cylinders 3, two sliding frames 5 are slidably installed on the lifting plate 4, a clamping assembly 9 is arranged in the sliding frame 5, and a clamping frame 6 is installed below the clamping assembly 9.

[0022] The clamping assembly 9 includes two moving racks 91 that are arranged inside the sliding frame 5 for forward and backward movement, and two groups of symmetrically distributed moving gears 92 are installed inside the sliding frame 5 through bearings and shafts for rotation. The moving gear 92 is meshed with the moving rack 91 for transmission, and a connecting gear 93 is fixed on the front side of the moving gear 92. A clamping cylinder 7 is installed on the top of the sliding frame 5. The push rod of the clamping cylinder 7 extends into the sliding frame 5 and is connected to a pushing rack 71. The pushing rack 71 is provided with two groups and is slid up and down in the sliding frame 5. The two groups of pushing racks 71 are respectively meshed with the connecting gears 93 on both sides. The extension and retraction of the push rod of the clamping cylinder 7 can make the pushing rack 71 move up and down, and then make the connecting gear 93 rotate, and the moving gear 92 will rotate together, so that the moving rack 91 can move inward or outward, change the distance between the two clamping frames 6, and then fix the workpiece between the two clamping frames 6.

[0023] A limiting block is set on the rear side of the movable rack 91, and the sliding frame 5 includes two T-shaped plates, which are connected by a plate material, and a limiting groove is opened on the rear T-shaped plate. The limiting block is slidably placed in the limiting groove, which can limit the moving distance of the movable rack 91 and prevent it from detaching from the sliding frame 5, thereby improving safety.

[0024] A vertical plate 94 is installed below the movable rack 91 by screws, and a clamping frame 6 is installed on the inner side of the vertical plate 94 by screws. The clamping frame 6 is an L-shaped structure, and the chamfered corners at the upper edge of the inner side of the clamping frame 6 form a contact arc surface 61. When the clamping frame 6 clamps column-type or shaft-type parts, its lower two sides will be located below the outer side of the workpiece and contact it. The design of the contact arc surface 61 can avoid scratching it.

[0025] Each sliding frame 5 is installed with a mounting plate 8 on both the front and rear sides of the upper side by screws, a rectangular opening is formed between the mounting plate 8 and the sliding frame 5, and a threaded hole is opened above the mounting plate 8, the threaded hole is connected to the rectangular opening, so that the sliding frame 5 can be quickly installed above the lifting plate 4, and it can be moved as needed.

[0026] An adjusting slide hole 41 is provided on the lifting plate 4, and the upper part of the sliding frame 5 passes through the adjusting slide hole 41 and is placed above the lifting plate 4, and the rectangular opening is designed to slide with the surface of the sliding frame 5, and a locking bolt is threadedly connected to the threaded hole, and the bottom end of the locking bolt is in close contact with the upper surface of the lifting plate 4. The sliding frame 5 and the clamping cylinder 7 can be directly placed above the lifting plate 4 through the adjusting slide hole 41, which is convenient for their installation, and the distance between the clamping frames 6 on the left and right sides can be adjusted according to the actual length of the workpiece, so that it is suitable for workpieces of various lengths.

[0027] The implementation principle of a loading and unloading robot in the embodiment of the present application is as follows: when clamping a workpiece, the lifting cylinder 3 causes the lifting plate 4 to move downward, thereby enabling the two groups of clamping assemblies 9 and the clamping frames 6 to move downward together, and the two clamping frames 6 in each group of the clamping frames 6 are respectively located on both sides of the outside of the workpiece, and then the push rod of the clamping cylinder 7 contracts to push the rack 71 upward, thereby enabling the moving rack 91 to move inward, and at this time, the distance between the two clamping frames 6 in the same group gradually decreases and the workpiece is placed between the two clamping frames 6, so that the workpiece can be fixed, which is convenient for subsequent loading or unloading operations;

[0028] The spacing between the left and right sliding frames 5 is adjusted according to the actual length of the workpiece, so that the clamping frame 6 can fix the two ends of the workpiece, making it more stable when loading and unloading. Specifically, the locking bolts are loosened, and the mounting frame can be moved inward or outward. After moving to the desired position, the locking bolts can be tightened.

[0029] By arranging a clamping assembly 9 in the sliding frame 5, and clamping frames 6 are provided at both the front and rear ends below the clamping assembly 9, the clamping frame 6 can clamp and fix the outer surface of the workpiece, is suitable for workpieces of various different diameters, and can clamp hollow pipes or solid shaft parts, and has diversity;

[0030] By sliding the sliding frame 5 left and right above the lifting plate 4, the distance between the two sliding frames 5 can be adjusted arbitrarily as needed, so that the clamping frame 6 can fix the two ends of the workpiece, making it more stable when loading and unloading.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
