The utility model discloses a device for releasing the twist alarm of inner milling center frame, which is used for milling the main journal of crankshaft and the connecting rod journal. A sliding table is arranged on the left side of the center frame and connected with the guide rail horizontally arranged on the bed. A connecting rod is fixed on the sliding table. A frame is fixedly connected with the sliding table. A connecting plate is arranged on the frame. A through hole is drilled on the lower right side surface of the center frame. A second oil cylinder is arranged on the lower right side surface of the center frame. A guide hole is drilled on the end surface of the center frame close to the second oil cylinder. A traction mechanism is arranged between the two guide grooves and at the lower end of the center frame. A first oil cylinder is vertically downwardly arranged on the upper surface of the center frame above the traction mechanism. The piston rod of the first oil cylinder is directly inserted into the square hole of the center frame. When the center frame is horizontally moved, the sliding table drives the connecting rod and the connecting plate to move. The piston rod of the first oil cylinder is inserted into the connecting rod in the guide hole. The piston rod of the first oil cylinder tightly presses the connecting plate on the lower side of the square hole. Since the center frame has three points that can be affected by the traction force, the parallel traction force between the center frame and the guide rail can be effectively maintained.

The utility model relates to the technical field of petroleum machinery spare and accessory part detection, in particular to a workpiece clamp for detecting defects of petroleum machinery spare and accessory parts. Comprising a U-shaped support, universal wheels are arranged at the four corners of the bottom of the U-shaped support, two vertical plates are installed on the inner wall of the top of the U-shaped support in a sliding mode, two hydraulic cylinders are fixedly installed on the two sides of the U-shaped support, and output rods of the hydraulic cylinders extend into the U-shaped support and are fixed to the corresponding vertical plates; sliding plates are slidably mounted on the sides, close to each other, of the two vertical plates, clamps are arranged on the sides, close to each other, of the two sliding plates, sliding grooves are formed in the sides, close to each other, of the two vertical plates, and two first sliding blocks are slidably mounted in the sliding grooves. Through the simple clamping structure, the petroleum machine part can be stably clamped, so that the part can be prevented from shaking or falling off in the moving and detecting process, and great convenience is brought to defect detection work of the petroleum machine part.

The utility model relates to an automatic product discharging structure which comprises a first clamping plate and a second clamping plate. The automatic product discharging structure is simple in structure and ingenious in design, the first clamping plate and the second clamping plate are matched with each other to position a product, and the conveying face of the driving roller shaft assembly and the conveying face of the driven roller shaft assembly abut against the two opposite side faces of the product in the discharging channel correspondingly, so that the product is stressed more evenly; when the first driving assembly drives the driving roll shaft assembly to rotate clockwise, acting force for moving in the discharging direction is applied to a product, the product drives a driven roll shaft to rotate anticlockwise while moving forwards, friction force between the product and a second clamping plate is reduced, and the product quality is improved. In addition, the driven roll shaft assembly further provides counter-acting force towards the discharging direction for the products, so that the products move more stably in the transverse moving process, the bumping or instability situation is avoided, more accurate transverse moving of the products can be achieved, the production efficiency is improved, and loss is reduced.
