Description

Technical Field

[0001] This utility model relates to the technical field of tile pulling devices, specifically a tile pulling limit sensing device that is easy to maintain. Background Technology

[0002] In the field of mechanical manufacturing, "pulling" is a key process in the hydraulic processing of thin-plate parts. These thin plates are usually used as basic components of transmission or support parts and are widely used in equipment such as engines and reducers. Their forming accuracy directly determines the subsequent assembly quality and the stability of the entire machine operation. However, existing pulling devices still have certain defects, such as: The patent application CN202122535629.4, entitled "Tile Pulling Device at the End of Synthetic Resin Tile Production Line," includes: a frame, with front and rear support rollers on the frame; a sliding frame and a sliding drive device that can slide back and forth on the frame between the front and rear support rollers; a channel for synthetic resin tiles to pass through on the sliding frame; a pressure plate in the channel; and a pressure plate drive device on the sliding frame. The pressure plate moves downward under the drive of the pressure plate drive device to press the synthetic resin tile. Several arc-shaped grooves are provided on the lower surface of the pressure plate. However, this device cannot automatically push the workpiece out after processing, leading to reduced work efficiency and failing to meet usage requirements. Therefore, a tile pulling limit sensing device that is easy to maintain is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a pull-tile limit sensing device that is easy to maintain, in order to solve the problem mentioned in the background art that the existing pull-tile device cannot automatically push the workpiece out after processing, which leads to a reduction in work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a base, an equipment frame, and a hydraulic jack assembly. The lower end face of the equipment frame is fixedly connected to the upper end face of the base, and the lower end face of the equipment frame is also fixedly connected to the upper end face of the hydraulic jack assembly. An equipment cavity is provided inside the base, and a dual-axis motor is fixedly connected to the bottom surface of the base. Rotating rods are fixedly connected to the shaft ends on both sides of the dual-axis motor, and helical gears are fixedly connected to the outer end faces of the rotating rods. Threaded rods are connected to the bearings on the front and rear inner walls of the base, and the helical gears are fixedly connected to the threaded rods. The rotating rods are driven by meshing with the threaded rods through the helical gears. A movable column is threadedly connected to the threaded rod, and a clamping plate is rotatably connected to the upper end face of the movable column. A roller is rotatably connected to the upper right end face of the clamping plate.

[0005] The above technical solution facilitates the limit adjustment and maintenance of the puller device.

[0006] As a preferred embodiment of this utility model, a torsion spring is provided at the connection between the movable column and the card plate, and the two ends of the torsion spring are respectively connected to the movable column and the card plate.

[0007] The above technical solution facilitates the automatic reset of the card plate when it is not subjected to external force.

[0008] As a preferred embodiment of this utility model, a sliding rod is slidably connected to the movable column, and both ends of the sliding rod are fixedly connected to the inner wall of the base.

[0009] The above technical solution facilitates the limiting of the moving column, preventing it from rotating with the threaded rod, thereby improving the stability and accuracy of the equipment.

[0010] As a preferred embodiment of this utility model, the upper surface of the base is provided with a sliding groove corresponding to the card plate; an electric telescopic rod is fixedly connected to the lower surface of the equipment frame, and an electric slide rail is fixedly connected to the lower surface of the electric telescopic rod; a pneumatic suction cup is fixedly connected to the lower surface of the electric slide rail.

Various electrical components, such as switches, relays, and PLC controllers, can be installed in the integrated electrical cabinet to achieve automated control and monitoring of the equipment.

[0014] As a preferred embodiment of this utility model, a workbench is provided on the upper surface of the base, and an infrared sensor is fixedly connected to the upper surface of the workbench; an infrared sensor is fixedly connected to the lower surface of the pneumatic suction cup; and an inspection door is rotatably connected to the front surface of the base, with a heat dissipation window provided on the inspection door.

[0015] The above technical solution facilitates the accurate positioning and automatic sensing functions of the equipment.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the device realizes the automated movement and positioning of the equipment through the coordinated arrangement of components such as electric telescopic rod, electric slide rail and pneumatic suction cup, which greatly improves work efficiency and reduces labor costs.

[0017] 1. When the conveyor belt moves the workpiece to the front of the base, the infrared sensor at the lower end of the pneumatic suction cup detects the presence of the workpiece. Then, the electric telescopic rod starts to work, driving the electric slide rail and the pneumatic suction cup to move downwards, so that the pneumatic suction cup is tightly attached to the surface of the workpiece. The suction force generated by the pneumatic suction cup firmly adsorbs the workpiece and moves it directly under the hydraulic top. Then, the pneumatic suction cup puts the workpiece down. Then, the infrared sensor on the worktable detects the presence of the workpiece and transmits the signal to the controller in the integrated electrical cabinet. At this time, the laser alignment sensors on both sides of the hydraulic top immediately detect the edge position of the workpiece. If the deviation exceeds 0.1mm, the controller triggers the electric slide rail to perform a second fine adjustment. After the fine adjustment is completed and the position is confirmed to be correct, the integrated electrical cabinet sends a pressing signal to the hydraulic top. The hydraulic top assembly controls the hydraulic top to perform the pressing operation on the workpiece. After the operation is completed, the integrated electrical cabinet sends a signal to the dual-axis motor. 2. The dual-axis motor drives the threaded rod to rotate via a rotating rod and a helical gear. The threaded rod drives the moving column to move to the right side of the base. When the moving column moves to the bottom of the sliding groove of the base, the clamping plate automatically flips under the action of the torsion spring and is in a vertical position. The clamping plate pushes the edge of the workpiece, thus pushing the processed workpiece out of the worktable. Then the dual-axis motor reverses and controls the moving column to reset. When the clamping plate abuts against the sliding groove, because the upper right side of the clamping plate is rotatably connected to a roller, the roller first contacts the inner wall of the sliding groove and is pushed to the right. Combined with the rotational connection between the left side of the clamping plate and the moving column, under the guidance and pushing action of the roller, the clamping plate bends to the right around the rotation axis. At this time, the torsion spring is deformed and stores force. After the moving column continues to reset to the initial position, the clamping plate remains bent and is stored in the sliding groove, preparing for the automatic flipping and reset when the workpiece is pushed out again (an infrared beam sensor is set at the worktable exit. After the workpiece has completely passed through, a "clear signal" is sent to the integrated electrical cabinet; otherwise, an alarm is triggered and the next round is paused).

A torsion spring 10 is provided at the connection between the movable column 8 and the clamping plate 9, and the two ends of the torsion spring 10 are respectively connected to the movable column 8 and the clamping plate 9, so that the clamping plate 9 can automatically reset when it is not subjected to external force. A sliding rod 11 is slidably connected to the movable column 8, and both ends of the sliding rod 11 are fixedly connected to the inner wall of the base 1, which facilitates limiting the movable column 8 and prevents the movable column 8 from rotating with the threaded rod 7, thereby improving the stability and accuracy of the equipment. The upper surface of the base 1 is provided with a sliding groove corresponding to the card plate 9; the lower surface of the equipment frame 2 is fixedly connected to an electric telescopic rod 12, and the lower surface of the electric telescopic rod 12 is fixedly connected to an electric slide rail 13; the lower surface of the electric slide rail 13 is fixedly connected to a pneumatic suction cup 14, which facilitates the improvement of the automation level of the device. A comprehensive electrical cabinet 15 is provided on the right end of the base 1, which facilitates centralized control and management of the equipment's electrical system, thereby improving the overall operating efficiency and safety of the equipment. Various electrical components, such as switches, relays, and PLC controllers, can be installed inside the comprehensive electrical cabinet 15 to realize automated control and monitoring of the equipment. A workbench is provided on the upper surface of the base 1, and an infrared sensor is fixedly connected to the upper surface of the workbench; an infrared sensor is fixedly connected to the lower surface of the pneumatic suction cup 14; an inspection door is rotatably connected to the front surface of the base 1, and a heat dissipation window is provided on the inspection door to facilitate the accurate positioning and automatic sensing function of the equipment. Working principle: When the conveyor belt moves the workpiece to the front of the base 1, the infrared sensor at the lower end of the pneumatic suction cup 14 detects the presence of the workpiece. Then, the electric telescopic rod 12 starts to work, driving the electric slide rail 13 and the pneumatic suction cup 14 to move downward, so that the pneumatic suction cup 14 is tightly attached to the surface of the workpiece. The suction force generated by the pneumatic suction cup 14 firmly adsorbs the workpiece and moves the workpiece directly under the hydraulic top. Then, the pneumatic suction cup 14 puts the workpiece down. Then, the infrared sensor on the worktable detects the presence of the workpiece and transmits the signal to the controller in the integrated electrical cabinet 15. At this time, the laser alignment sensors on both sides of the hydraulic top immediately detect the edge position of the workpiece. If the deviation exceeds 0.1mm, the controller triggers the electric slide rail 13 to perform a second fine adjustment. After the fine adjustment is completed and the position is confirmed to be correct, the integrated electrical cabinet 15 sends a pressing signal to the hydraulic top. The hydraulic top assembly 3 controls the hydraulic top to perform the pressing operation on the workpiece. After the operation is completed, the integrated electrical cabinet 15 sends a signal to the dual-axis motor 4. The dual-axis motor 4 drives the threaded rod 7 to rotate via the rotating rod 5 and the helical gear 6. The threaded rod 7 drives the moving column 8 to move to the right side of the base 1. When the moving column 8 moves to the bottom of the sliding groove of the base 1, the clamping plate 9 automatically flips under the action of the torsion spring 10 and is in a vertical position. The clamping plate 9 pushes the edge of the workpiece, thereby pushing the processed workpiece out of the worktable. Then the dual-axis motor 4 reverses and controls the moving column 8 to reset. When the clamping plate 9 abuts against the sliding groove, because the upper right side of the clamping plate 9 is rotatably connected to a roller, the roller first makes contact with the sliding groove. The wall contacts and is pushed to the right; combined with the rotational connection between the left side of the clamping plate 9 and the moving column 8, under the guidance and pushing action of the roller, the clamping plate 9 bends to the right around the rotation axis. At this time, the torsion spring 10 is deformed and stores force. After the moving column 8 continues to reset to the initial position, the clamping plate 9 remains bent and is stored in the sliding groove, preparing for the automatic flipping and reset when the workpiece is pushed out next time (an infrared beam sensor is set at the workbench exit. After the workpiece has completely passed, a "clear signal" is sent to the integrated electrical cabinet 15. Otherwise, an alarm is triggered and the next round is paused).
