Description

Technical Field

[0001] The utility model relates to the technical field of guide rod detection devices, and specifically relates to a guide rod detection device for a die-casting machine clamping mechanism. Background Technique

[0002] The clamping mechanism of a die-casting machine is a device used to fix the mold and ensure the stability of the mold during the entire die-casting process. The guide rod, also known as the guide pillar, is an important part of the clamping mechanism. Its function is to guide and support the mold, and maintain the accurate alignment of the mold during the mold opening and closing process. Specifically, it is usually composed of more than two cylindrical rods, one end is connected to the template, and the other end is connected to the mold base; it can keep the mold stable during the movement process and prevent the mold from losing alignment due to friction or vibration.

[0003] During the use of the guide rod, in order to prevent accidents, it is necessary to detect the inside of the guide rod to prevent cracks from appearing inside the guide rod, which will affect the load-bearing effect of the guide rod. The guide rod detection device is generally an ultrasonic detector. The ultrasonic detector generally includes a main unit and an ultrasonic probe. The ultrasonic probe collects the internal data of the guide rod, and then the main unit identifies and analyzes the data to judge whether there are cracks.

[0004] The patent with the publication number of CN216816551U currently discloses a digital ultrasonic flaw detector, including an ultrasonic flaw detector. A first rotating shaft is arranged at the upper end of the ultrasonic flaw detector, and a first cover plate is installed at the upper end of the first rotating shaft. A magnetic strip is installed on the inner wall of the first cover plate, and both ends of the magnetic strip are screwed to a first fixing rod. A connecting block is welded on one side of the ultrasonic flaw detector, and a second rotating shaft is installed on the inner wall of the connecting block. A support rod is installed on the outer wall of the second rotating shaft, and one end of the support rod is attached to a soft rubber sleeve. A limiting rod is installed on the inner wall of the support rod, and a magnetic block is installed at one end of the limiting rod. A second fixing rod is screwed on one side of the ultrasonic flaw detector. This digital ultrasonic flaw detector is provided with a third fixing rod and a magnetic sleeve. By setting the third fixing rod to play a role in thread fixing for the magnetic sleeve, when using the device, the setting of the magnetic sleeve is convenient for anti-disconnection fixing of the device connection, increasing the stability of the device.

[0005] Although the above device solves the problem of inconvenient support for the ultrasonic device during use, there are still the following problems:

[0006] The existing detection method is that the staff holds an ultrasonic probe and fits the ultrasonic probe to the outer wall of the guide rod to obtain a set of data. By continuously moving the position of the ultrasonic probe, multiple sets of data are obtained, and all the data are integrated to identify whether there is a crack in the guide rod. This method requires manual detection of the guide rod, resulting in waste of the staff's working time, increased workload of the staff, and occupation of the staff, leading to a reduction in production efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] As Figures 1 to 6 shown, a detection device for the guide rod of the die-casting machine clamping mechanism includes a main machine 1 and an ultrasonic probe 2 connected to the main machine 1. A base 3 is fixedly connected to the outer wall of the main machine 1. The main machine 1 is located on the surface of the base 3. A robotic arm 4 is fixedly connected to the middle of the base 3. A connecting column 5 is fixedly connected to the output end of the robotic arm 4. Connecting blocks 6 are fixedly connected to both ends of the connecting column 5. A connecting plate 7 is fixedly connected to the side of the connecting block 6 away from the connecting column 5. The connecting plate 7 is arranged as an arc-shaped plate. The ultrasonic probe 2 is connected to the middle of one connecting plate 7.

[0025] As Figure 1 shown, the detection device for the guide rod of the die-casting machine clamping mechanism in the present utility model is similar in structure to the existing guide rod detection device. For example, a digital ultrasonic flaw detector disclosed in the patent with the publication number CN216816551U. The main improvement point of the present utility model is that the detection device can automatically detect the guide rod. As Figures 1 to 6 shown, when the detection device for the guide rod of the die-casting machine clamping mechanism in the present utility model is in use, after the clamping mechanism of the die-casting machine works for a period of time, the robotic arm 4 will control the movement of the connecting plate 7, so that the ultrasonic probe 2 contacts the outer wall of the guide rod, realizing the acquisition of the internal data of the guide rod. Then the data is calculated and displayed by the main machine 1 to detect the cracks inside the guide rod. When cracks are detected inside the guide rod, the crack information is sent to the terminal of the staff to issue an alarm to the staff.

[0026] It should be noted that the robotic arm 4 is a mature product of the existing technology. Through the robotic arm 4, 360-degree rotation of the connecting column 5 can be realized, thereby realizing the omnidirectional detection of the guide rod by the ultrasonic probe 2 and obtaining accurate and comprehensive internal data of the guide rod.

[0027] By arranging the robotic arm 4 on the base 3 and the ultrasonic probe 2 on the connecting plate 7, and using the mutual cooperation of the robotic arm 4 and the ultrasonic probe 2, the automatic detection of the guide rod is realized through the robotic arm 4, thereby reducing the working intensity of the staff, reducing the workload of the staff, and improving the production efficiency.

[0028] As Figures 1 to 3 shown, elastic blocks 8 are fixedly connected to both sides of the surface of the connecting plate 7 connected with the ultrasonic probe 2. A moving component is connected to the side of the ultrasonic probe 2 close to the connecting plate 7.

[0029] Specifically, by using the elastic block 8, the ultrasonic probe 2 can be made to fit more closely to the outer wall of the guide rod, so that the ultrasonic probe 2 can detect the guide rod more accurately, improving the accuracy of the detection result.

[0030] As Figure 3 shown, the moving component includes a sliding block 9 and a pressure spring 12. Both the sliding block 9 and the pressure spring 12 are fixedly connected to the ultrasonic probe 2. The surface of the connecting plate 7 is provided with a sliding groove 10 and a placement groove 11 corresponding to the positions of the sliding block 9 and the pressure spring 12.

[0031] Specifically, by using the pressure spring 12, the position of the ultrasonic probe 2 can be slightly moved, making it more convenient for the ultrasonic probe 2 to fit the guide rod. The setting of the sliding block 9 and the sliding groove 10 can prevent the pressure spring 12 from bending and causing the ultrasonic probe 2 to shift, improving the stability of the ultrasonic probe 2.

[0032] As Figure 2 、 Figure 4 and Figure 5 shown, a brush 13 is fixedly connected to the surface of the connecting plate 7 away from the ultrasonic probe 2. The connecting plate 7 is provided with a plurality of oil outlet holes 14. An oil guide groove 15 is opened in the connecting plate 7 and is communicated with the oil outlet holes 14. An oil inlet groove 16 is opened in the connecting block 6 and is communicated with the oil guide groove 15. One end of the oil inlet groove 16 is connected with an oil inlet component, and a control valve is connected to the inner wall of the oil inlet groove 16.

[0033] Specifically, after the ultrasonic probe 2 finishes detecting the guide rod, the robotic arm 4 will control the connecting column 5 to rotate 180 degrees, making the brush 13 face the guide rod. Then the robotic arm 4 controls the brush 13 to fit the outer wall of the guide rod. At this time, the lubricating oil will enter the oil guide groove 15 from the oil inlet groove 16, and then enter the brush 13 through the oil outlet holes 14, and then the lubricating oil is applied to the outer wall of the guide rod by the brush 13; through this setting, the work of automatically replenishing lubricating oil for the guide rod is realized, further reducing the working intensity of the staff and increasing the overall practicality of the detection device.

[0034] As Figure 6 shown, the oil inlet component includes an oil guide pipe 17, a water pump 19, an oil inlet 20 and a protective cover 21. One end of the oil guide pipe 17 is communicated with the oil inlet groove 16. An oil storage tank 18 is opened in the base 3. A water pump 19 is fixedly connected to the inner wall of the oil storage tank 18. One end of the oil guide pipe 17 penetrates the surface of the base 3 and is communicated with the water pump 19. An oil inlet 20 communicated with the oil storage tank 18 is fixedly connected to the surface of the base 3. The protective cover 21 is sleeved on the outer wall of the oil inlet 20.

[0035] Specifically, the staff adds lubricating oil into the oil storage tank 18 through the oil inlet 20, and uses the water pump 19 to enable the lubricating oil in the oil storage tank 18 to pass through the water pump 19, the oil guide pipe 17, the oil inlet groove 16, the oil guide groove 15 and the oil outlet hole 14 in sequence and enter the brush 13.

[0036] As Figure 4 shown in Figure 5 As shown, the control valve includes a flow-limiting ball 22, a limiting spring 23 and a moving rod 24. A limiting groove 26 is formed in the inner wall of the oil inlet groove 16. The flow-limiting ball 22 is located in the limiting groove 26. Two ends of the limiting spring 23 are fixedly connected to the outer wall of the flow-limiting ball 22 and the inner wall of the limiting groove 26 respectively. One end of the outer wall of the flow-limiting ball 22 away from the limiting spring 23 is fixedly connected to a moving rod 24. A moving groove 25 corresponding to the position of the moving rod 24 is formed on the surface of the connecting plate 7. One end of the moving rod 24 is in contact with the surface of the brush 13.

[0037] Specifically, when the brush 13 is about to be in contact with the outer wall of the guide rod, the guide rod will first squeeze the moving rod 24, causing the moving rod 24 to retract into the moving groove 25. The moving rod 24 will drive the flow-limiting ball 22 to move, causing the flow-limiting ball 22 to lose the blockage of the limiting groove 26. At this time, the lubricating oil will enter the oil guide groove 15 through the limiting groove 26 and will not enter the brush 13; when the brush 13 is separated from the guide rod, under the action of the limiting spring 23, the flow-limiting ball 22 will block the limiting groove 26 again, preventing the lubricating oil from entering the brush 13; through this setting, the control of the lubricating oil can be realized, preventing the excessive lubricating oil on the brush 13 from dripping on the ground and reducing the waste of the lubricating oil.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
