Abstract
Description
Technical Field
[0001] This utility model relates to the field of six-sided hydraulic press technology, and in particular to a hammer position detection system for a six-sided hydraulic press. Background Technology
[0002] As is widely known, the current method of hammer calibration is mainly done manually. A saw blade is used to score the hammer, and the flatness of the hammer surface is judged by human touch and visual inspection. The hammer position changes after each synthesis, and the hammer needs to be recalibrated and adjusted before each synthesis. Hammer calibration also relies on manual labor, takes a long time before each synthesis, and the results of each calibration are different. The low calibration accuracy affects the synthesis result. Utility Model Content
[0003] In order to overcome the shortcomings of the background technology and solve the existing technical problems, this utility model discloses a six-sided top press hammer position detection system, which improves the detection and adjustment efficiency and effect through automatic visual detection and hammer rotation.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A six-sided top press hammer position detection system includes a main control device, a drive motor, a slewing bearing, a steel ring, a top hammer clamped to the head end of the steel ring, and a large pad fixedly installed at the end of the top press telescopic rod. The inner ring end face of the slewing bearing is fixedly connected to the large pad, and the toothed outer ring of the slewing bearing is fixedly connected to the tail end face of the steel ring. The steel ring has a small pad corresponding to the top hammer and the large pad. A drive gear is coaxially fixed to the output shaft of the drive motor of the main control device, and the drive gear is correspondingly meshed with the toothed outer ring of the slewing bearing through a gear set. The main control device is connected to a three-dimensional vision detection module for detecting the top of the top hammer.
[0005] Furthermore, the large pad includes a base plate and a protruding column located at the center of the upper surface of the base plate. The base plate is detachably installed on the end face of the telescopic rod of the top press by means of a bolt assembly, and the inner ring of the slewing bearing is coaxially fixed to the top surface of the protruding column.
[0006] Furthermore, the gear set includes multiple intermediate gears rotatably mounted on the base plate of the large pad.
[0007] Furthermore, the 3D vision inspection module includes two linear array structured light cameras and a laser displacement sensor.
[0008] Furthermore, the main control device is set as a PLC or an industrial computer.
[0009] Furthermore, the drive motor is configured as a servo motor.
[0010] By adopting the technical solution described above, this utility model has the following beneficial effects: The six-sided top press hammer position detection system disclosed in this utility model overcomes the limitations of existing technologies that rely on manual visual inspection or single-point contact measurement by utilizing a three-dimensional vision detection module. It achieves multi-angle collaborative calibration, resulting in higher accuracy and efficiency. Furthermore, by using a motor to drive a steel ring to automatically rotate the top hammer, it not only saves manpower and facilitates multi-directional visual acquisition, but also helps to automatically adjust the top hammer into position, thereby improving the detection effect.

[0013] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.
[0014] Combined with appendix Figures 1-2 The six-sided top press hammer position detection system includes a main control device 9, a drive motor 8, a slewing bearing 3, a steel ring 5, a top hammer 1 clamped to the head end of the steel ring 5, and a large pad 4 fixedly installed at the end of the top press telescopic rod. The head end of the steel ring 5 is generally square. After the top hammer 1 is inserted, it can rotate and adjust together with the steel ring 5. As attached Figure 1 As shown, the lower end face of the inner ring of the slewing bearing 3 is fixedly connected to the large pad 4, and the upper end face of the toothed outer ring of the slewing bearing 3 is coaxially fixedly connected to the tail end face of the steel ring 5. The steel ring 5 is provided with a small pad 2 corresponding to the top hammer 1 and the large pad 4. The small pad 2 is used to abut against the top hammer 1. Specifically, the large pad 4 includes a base plate and a protruding column located in the center of the upper plate of the base plate, thereby forming a step to facilitate the installation of gear sets and bolts. The base plate can be detachably installed on the end face of the telescopic rod of the top press through a bolt assembly. The inner ring of the slewing bearing 3 is coaxially fixed to the top surface of the protruding column. The signal connection and the output shaft of the drive motor 8 of the main control device 9 are coaxially fixed with a drive gear 7. The drive gear 7 is meshed with the toothed outer ring of the slewing bearing 3 through a gear set. The main control device 9 controls the drive motor 8 to start, thereby driving the steel ring 5 and the top hammer 1 to rotate and adjust. Specifically, the gear set includes two intermediate gears 6 rotatably mounted on the bottom plate of the large pad block 4. Through the transmission of the intermediate gears 6, it is easy to mount the drive motor 8 to the outside to prevent it from affecting the normal operation of the top hammer 1. If necessary, the drive motor 8 is set as a servo motor. The servo motor can accurately control the rotation angle and rotation direction, which is conducive to the efficient adjustment of the top hammer 1. The main control device 9 is connected to a 3D vision inspection module 10 for detecting the top of the hammer 1. As needed, the 3D vision inspection module 10 includes two linear array structured light cameras and a laser displacement sensor. It sets a dynamic tolerance zone for the edge angle as the core detection indicator, overcoming the limitations of existing technologies that rely on manual visual inspection or single-point contact measurement. It acquires 3D point cloud data of the hammer 1's edges using an industrial-grade 3D vision sensor (such as the Keyence LJ-X8000 series, with an accuracy of ±0.01mm), and calculates the angle between the edges. For example, a standard angle of 90°±0.2° is set. When the measured value exceeds this range, an adjustment prompt is triggered, ultimately achieving 360° scanning of the hammer 1's edges without blind spots. The structured light cameras are used to acquire the surface texture features of the edges, and the laser sensor is used to measure the height difference between the edges, with an accuracy of ±0.005mm. Furthermore, the main control device 9 is configured as a PLC or industrial computer to realize signal reception, processing, and feedback adjustment control.
[0015] The six-sided top press hammer position detection system described in this utility model differs from existing technologies that rely on manual hammer calibration, which suffers from low precision, poor efficiency, and a single calibration time exceeding 15 minutes, and cannot achieve multi-edge collaborative calibration. This system utilizes a three-dimensional vision detection module 10 to achieve ±0.05° accuracy through 3D vision detection. Combined with the drive motor 8 to rotate and adjust the top hammer 1, the calibration time is reduced to less than 10 minutes, significantly improving detection efficiency and effectiveness.
