Description

Technical Field

[0001] The utility model belongs to the technical field of clamping devices, in particular to a rotary clamp of a drilling rig. Background Art

[0002] A drilling rig is composed of machines, units and mechanisms. In metal processing or pump body bridge housing grinding operations, the main function of the drilling rig is to use a drill or grinding wheel to operate on metal. The metal parts on the surface of the workbench are fixed by fixtures and the operation is performed according to demand. A fixture refers to a device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture.

[0003] In the prior art, the clamping device is a device for holding an object and then manipulating the object. It can clamp and release the object while performing certain actions. The clamping device is usually composed of a positioning element, a clamp, a locking rod, a motor, and a cylinder. When performing a clamping operation, the clamp is usually driven by a cylinder machine to move, thereby driving the locking rod to fix the metal parts that need to be fixed. It is a necessary device for the drilling rig to operate.

[0004] In the prior art, the clamping devices on the market are usually composed of several groups of fixed gripping rods. During operation, the grippers are driven by motors and cylinders to clamp metal parts. However, there are many types of metal parts. When facing different metal parts, it is necessary to frequently replace the types of locking rods, which results in short effective working time and low grinding efficiency. In addition, due to the complexity of the clamping device, it is time-consuming to disassemble the locking rod. Therefore, a rotary clamp for a drilling rig is proposed to address the above problems.

[0024] During operation, in the process of clamping metal parts, when the metal parts are too complicated, the locking rod 7 needs to be replaced frequently, which results in short effective working time and low grinding efficiency. In addition, due to the complexity of the clamping device, the locking rod 7 is time-consuming to disassemble. Therefore, in view of the above problems, a rotary clamp for a drilling rig is proposed. Through the operation of the cylinder body 15, the cylinder rod 17 is driven to operate. When the cylinder rod 17 performs telescopic operation, it will drive the clamping structure to move as a whole. When the output end of the cylinder base 14 operates, the cylinder rod 17 of the cylinder base 14 will reciprocate. The cylinder rod 17 will drive the four groups of connecting plates 2 installed on the bottom cross plate 1, thereby driving the end slider 4 to perform reciprocating lifting operations, thereby realizing the overall support structure to perform repeated up and down movements, driving the four groups of locking rods 7 installed below to perform clamping operations.

[0025] Furthermore, both ends of the cross bar 6 are installed in the middle of the bottom assembly plate 11, four groups of cross bars 6 are installed on the side of the bottom assembly plate 11, four support rods 13 are installed on the surface of the bottom assembly plate 11, the ends of the support rods 13 pass through the bottom assembly plate 11, nuts 9 are installed at the ends of the support rods 13, and gaskets 12 are installed between the nuts 9 and the middle of the bottom assembly plate 11.

[0026] When working, the clamping device on the market is usually composed of several groups of fixed grab bars. During operation, the motor and the cylinder drive the gripper to clamp the metal parts. The bottom motor 10 installed on the surface of the bottom assembly plate 11 drives the middle connecting rod 3 at the output end to perform telescopic operation, thereby driving the tic-tac-toe bottom plate 1 to move, and the connecting plate 2 will swing with the upper line, and the end slider 4 will operate synchronously with the connecting plate 2.

[0027] Furthermore, the other end of the support rod 13 passes through the upper fixing plate 18 for installation, and the upper fixing plate 18 is connected to the support rod 13 through a nut 9, and a gasket 12 is installed between the nut 9 and the middle of the upper fixing plate 18.

The other end of the cylinder rod 17 is connected to a cylinder body 15, and a cylinder base 14 is installed at the upper and lower ends of the cylinder body 15. Four groups of cylinder support rods 16 are installed on the surface of the cylinder base 14, and a bearing 19 is installed at the bottom of the cylinder base 14.

[0028] During operation, when the end slider 4 moves, the locking rod 7 installed in the middle of the end slider 4 will be driven to operate. The upper line movement of the end slider 4 will drive the locking rod 7 to open or close the shape to fix the metal part.

[0029] Working principle: In the process of clamping metal parts, when the metal parts are too complicated, the locking rod 7 needs to be replaced frequently, which results in short effective working time and low grinding efficiency. In addition, due to the complexity of the clamping device, the locking rod 7 is time-consuming to disassemble. Therefore, in view of the above problems, a rotary clamp for a drilling rig is proposed. Through the operation of the cylinder body 15, the cylinder rod 17 is driven to operate. When the cylinder rod 17 is telescopic, it will drive the clamping structure to move as a whole. When the output end of the cylinder base 14 is operating, the cylinder rod 17 of the cylinder base 14 will reciprocate. The cylinder rod 17 will drive the four sets of connecting plates 2 installed on the bottom tic-tac-toe bottom plate 1 below, thereby driving the end slider 4 to perform reciprocating lifting operations, thereby realizing overall support. The structure performs repeated up and down motions, driving the four groups of locking rods 7 installed below to perform clamping operations. The clamping devices on the market are usually composed of several groups of fixed grabbing rods. During operation, the motor and the cylinder drive the gripper to clamp the metal parts. The bottom motor 10 installed on the surface of the bottom assembly plate 11 drives the middle connecting rod 3 at the output end to perform telescopic operations, thereby driving the tic-tac-toe bottom plate 1 to move, and the connecting plate 2 will swing with the online operation, and the end slider 4 will work synchronously with the connecting plate 2. When the end slider 4 moves, it will drive the locking rod 7 installed in the middle of the end slider 4 to operate. Through the online movement of the end slider 4, the locking rod 7 will be driven to open or close, so as to fix the metal parts.
