Description

Technical Field

[0001] This utility model belongs to the field of magnetic force detection, specifically, it relates to an inspection device for the production of magnetic chucks. Background Technology

[0002] In modern industrial production, magnetic chucks are widely used in many fields such as machining and logistics handling due to their unique adsorption properties. The performance of magnetic chucks is directly related to the safety and stability of the production process. If the suction force of the chuck is insufficient, the workpiece may fall off unexpectedly during machining, which may not only damage the workpiece but also injure the operator. Therefore, it is essential to conduct strict quality inspection on magnetic chucks. However, existing magnetic detection devices increase the labor intensity of workers during use, and the inertia generated when the detection device falls off can easily cause workers to fall and get injured.

[0003] Chinese patent publication number CN222105624U discloses a magnetic force detection device for an electro-permanent magnet chuck. This device is supported by a first support frame and a second support frame, and uses a lifter to raise and lower a lifting rod to perform the detection work. It can effectively replace manual pulling of the detection cylinder for magnetic force detection, reducing the workload of personnel and avoiding injury to users. However, when the second support frame is raised by the lifter for magnetic detection, due to the setting of the shock absorber and spring, the chuck being tested also needs to overcome the elastic force of the spring and shock absorber when the first support frame and the detection cylinder pull the chuck block up. This will cause errors in the final detection results and reduce the accuracy of the inspection results.

[0004] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] Please see Figure 1-8As shown, this embodiment provides an inspection device for the production of magnetic chucks, including an inspection table 1, on which a placement rack 14 is fixedly installed. The placement rack 14 has a placement area 17 and a clamping assembly 8 for clamping the magnetic chucks in the placement area 17. Two sliding rods 15 are fixedly installed on the placement rack 14 relative to the placement area 17. A sliding plate 6 is sleeved on and slidably mounted on the two sliding rods 15. An adsorption block 19 is provided at the bottom of the sliding plate 6 relative to the placement area 17. A fixed frame 2 is fixedly installed on the inspection table 1. A lifting plate 3 is slidably mounted on the fixed frame 2. A cylinder 4 is provided on the fixed frame 2 to drive the lifting plate 3 to slide. A tension sensor 5 is fixedly installed on the lifting plate 3. A connecting rod 16 is fixedly installed between the test end of the tension sensor 5 and the sliding plate 6. A controller 13 is provided on the inspection table 1.

[0041] Specifically, the magnetic chuck is placed in the placement area 17 of the placement rack 14 and fixed by the clamping assembly 8. Then, the magnetic chuck is controlled to generate magnetic force. At the same time, the cylinder 4 drives the lifting plate 3 to move downward, causing the tension sensor 5 and the sliding plate 6 to descend. The sliding plate 6 slides along the sliding rod 15, so that the adsorption block 19 contacts and adsorbs the magnetic chuck. Then, the cylinder 4 pulls the lifting plate 3 upward. If the magnetic chuck adsorbs normally, it will generate tension. This tension is transmitted to the tension sensor 5 through the connecting rod 16. The controller 13 can receive the data from the tension sensor 5 to detect the adsorption force of the magnetic chuck. This can simulate the actual working scenario of the magnetic chuck. The tension sensor 5 accurately measures its adsorption force. The structure is simple and easy to operate. It can effectively detect the adsorption performance of the magnetic chuck, improve the inspection efficiency and accuracy. Compared with the prior art, this device avoids the influence of the spring 72 and the shock absorber on the inspection results, and improves the accuracy of the inspection.

[0042] It should be noted that in this embodiment, the tension sensor 5 (also known as a tension gauge or force sensor) converts physical tension into an electrical signal to accurately measure the magnetic attraction force on the test block. At the same time, the measured value of the tension sensor 5 needs to be monitored, recorded and analyzed in real time by external devices such as a data acquisition instrument, display and recording device, computer and analysis software. Secondly, the structure of the lifting plate 3 being slidably set on the fixed frame 2 is existing technology. Furthermore, in other embodiments, in order to accurately monitor whether the adsorption block 19 is connected to the magnetic suction cup, a position sensor can be installed on the fixed frame 2 at a position relative to the placement frame 14 to facilitate the automated processing of the device. Of course, the installation method and working principle are existing technologies and will not be described here.

[0043] In this embodiment, as Figures 1 to 5As shown, it also includes a cleaning component 9, which is set on the lifting plate 3. The cleaning component 9 includes a blower 91 fixedly installed on the lifting plate 3, an air outlet pipe 93 that passes through and is fixedly installed on the sliding plate 6, and an air supply pipe 92 whose two ends are respectively connected to the air outlet of the blower 91 and the air outlet pipe 93. The air outlet end of the air outlet pipe 93 is set towards the placement area 17. The blower 91 is signal connected to the controller 13. Specifically, after the clamping component 8 clamps the magnetic chuck, the controller 13 controls the blower 91 to start. The airflow generated by the blower 91 is delivered to the air outlet pipe 93 through the air supply pipe 92, and then blown from the air outlet pipe 93 to the magnetic chuck in the placement area 17, blowing away dust, debris and other impurities on the surface of the magnetic chuck, avoiding impurities from affecting the adsorption effect and detection accuracy of the magnetic chuck. The cleaning component 9 can automatically clean the magnetic chuck before detection, ensuring its surface is clean, reducing the interference of impurities on the detection results, improving the reliability of detection, and eliminating the need for manual cleaning, thus improving inspection efficiency.

[0044] In this embodiment, as Figures 3 to 6 As shown, the sliding plate 6 is provided with a buffer assembly 7, which includes a U-shaped plate 74, which is fixedly installed at the bottom of the sliding plate 6. Two movable rods 73 are movably connected through the U-shaped plate 74. The first ends of the two movable rods 73 are fixedly connected to the adsorption block 19, and the second ends of the two movable rods 73 are fixedly installed with limit plates 71. Two sets of springs 72 are respectively sleeved on the two movable rods 73. The two ends of the two sets of springs 72 respectively abut against the adsorption block 19 and the U-shaped plate 74. Specifically, when the adsorption block 19 contacts the magnetic suction cup, if there is a height difference... Or, due to impact force, the adsorption block 19 will drive the movable rod 73 to move on the U-shaped plate 74 and compress the spring 72. The spring 72 acts as a buffer, absorbing the impact energy and reducing the impact force on the adsorption block 19 and the magnetic chuck. At the same time, the limiting plate 71 can prevent the movable rod 73 from moving excessively. The buffer assembly 7 can effectively buffer the impact force when the adsorption block 19 contacts the magnetic chuck, protecting the surfaces of the adsorption block 19 and the magnetic chuck from damage, extending the service life of the equipment, and making the adsorption process more stable, thus improving the accuracy of the detection; at the same time, refer to Figure 6 As shown, when the cylinder 4 drives the sliding plate 6 to rise, the limiting plate 71 is engaged with the U-shaped plate 74. This ensures that the sliding plate 6 can drive the adsorption block 19 to apply a pulling force to the magnetic chuck, while avoiding the spring 72 from affecting the detection results.

[0045] In this embodiment, as Figures 3 to 6 As shown, two limiting sleeves 18 are respectively sleeved and fixedly installed on the sliding plates 6 along the two sliding rods 15. Specifically, the limiting sleeves 18 are fixed on the sliding rods 15 to provide a limiting function for the sliding plates 6, restricting the movement range of the sliding plates 6 on the sliding rods 15, and preventing the sliding plates 6 from sliding excessively and detaching from the sliding rods 15 or exceeding the normal working range.

[0046] In this embodiment, as Figures 3 to 6 As shown, the height of the air outlet end of the air outlet pipe 93 is higher than the height of the adsorption block 19, and the air outlet pipe 93 does not contact the magnetic chuck on the placement area 17.

[0047] In this embodiment, as Figures 3 to 8 As shown, the clamping assembly 8 includes a drive disk 84, which is rotatably mounted at the bottom of the placement frame 14 via a rotating shaft. The drive disk 84 is positioned relative to the placement area 17. The drive disk 84 is driven by a motor 81, which is fixedly mounted on the placement frame 14 and is signal-connected to the controller 13. Multiple clamping plates 85 are slidably mounted on the placement frame 14 around the placement area 17. Each clamping plate 85 has a slider 83 fixedly mounted on it. The slider 83 passes through and slides on the placement frame 14. The placement frame 14 has a groove 86 for the slider 83 to slide. Each slider 83 is rotatably connected to a drive rod 82, the other end of which is hinged to the drive disk 84. The drive disk 84 has a disc-shaped structure, and the drive rod 82 has an arc-shaped structure coaxial with the drive disk 84. The clamping plates 85 are embedded with elements that can fit against the outer wall of the magnetic chuck on the placement area 17. Specifically, in this embodiment, the placement frame 14, clamping plate 85, and slider 83 are preferably made of non-magnetic stainless steel (in other embodiments, aluminum alloy or other materials can be selectively chosen) to avoid affecting the test results of the magnetic chuck. The controller 13 controls the motor 81 to start, and the motor 81 drives the drive disk 84 to rotate. The drive disk 84 drives the slider 83 to slide in the slide groove 86 through the drive rod 82, thereby causing the multiple sets of clamping plates 85 surrounding the placement area 17 to move synchronously inward or outward, realizing the clamping or releasing of the magnetic chuck on the placement area 17. The clamping assembly 8 can automatically clamp and fix the magnetic chuck without manual operation, improving the detection efficiency. At the same time, it can ensure that the magnetic chuck remains stable during the detection process and avoid the impact of shaking on the accuracy of the detection results.

[0048] In this embodiment, as Figures 4 to 8As shown, each of the multiple clamping plates 85 has a top plate 20 at the end opposite to the slider 83. The clamping plates 85 are equipped with an adjustment assembly 21 for adjusting the height of the top plate 20. The adjustment assembly 21 includes an adjustment screw 212 and two fixing rods 211. The two fixing rods 211 are fixedly mounted on the top of the clamping plate 85 and pass through and are movably disposed on the top plate 20. The adjustment screw 212 passes through and is movably disposed on the top plate 20 and is threadedly connected to the clamping plate 85. Specifically, by rotating the adjustment screw 212, the height of the top plate 20 can be adjusted. The clamping plate 85 is threaded together, and the adjusting screw 212 moves up and down, thereby driving the top plate 20 to move up and down. The two fixing rods 211 guide and limit the top plate 20, ensuring that the top plate 20 moves smoothly. The position of the top plate 20 can be adjusted according to the height of the magnetic chuck, so that the top plate 20 can better contact the magnetic chuck and apply pressure. The height of the top plate 20 can be flexibly adjusted by adjusting the component 21 to adapt to magnetic chucks of different thicknesses or heights, improving the versatility of the clamping component 8 and ensuring good clamping and fixing of magnetic chucks of various specifications.

[0049] In this embodiment, as Figure 7 and Figure 8 As shown, a rubber pad 22 is fixedly installed inside the arc-shaped end face of the clamping plate 85. Specifically, the rubber pad 22 can prevent the clamping plate 85 from scratching the outer wall of the magnetic chuck, protect the surface quality of the magnetic chuck, and enhance the stability and reliability of clamping, so as to prevent the magnetic chuck from sliding or shaking during the testing process.

[0050] In this embodiment, as Figure 1 As shown, two side plates 10 are fixedly installed on the inspection table 1 along the placement rack 14. A door panel 11 is hinged between the two side plates 10. A viewing plate 12 is fixedly installed on the door panel 11 relative to the placement rack 14. Specifically, when inspecting the magnetic chuck, the door panel 11 can be closed, and the clamping and adsorption testing process of the magnetic chuck on the placement rack 14 can be observed through the viewing plate 12. After the inspection is completed, the door panel 11 can be opened to take out and put in the magnetic chuck. The door panel 11 can be opened and closed flexibly through the hinge structure with the side plates 10. After the door panel 11 is closed, it can form physical protection for the area of ​​the placement rack 14, avoiding the possible occurrence of parts falling off or splashing during the inspection process (such as when the adsorption block 19 separates from the magnetic chuck) and causing injury to the operator, thus improving the safety of equipment operation.

[0051] Working principle:

[0052] The magnetic chuck to be inspected is placed in the placement area 17 of the placement rack 14. The controller 13 starts the motor 81, which drives the drive plate 84 to rotate. The drive plate 84, via the drive rod 82, pushes multiple sets of clamping plates 85 to slide along the slide grooves 86 on the placement rack 14, thus firmly clamping the magnetic chuck and ensuring its fixed position during inspection. Then, the controller 13 sends a signal to the blower 91, which starts the blower and sends air through the air supply pipe 92 into the air outlet pipe 93. The air outlet pipe 93 blows the air towards the placement area 17 to clean the top of the magnetic chuck, removing any impurities and ensuring the accuracy of subsequent adsorption. Then, the magnetic chuck is made to generate magnetic force (the specific control depends on the type of magnetic chuck; this is existing technology). Afterwards, the controller 13 controls the cylinder 4 to work, pushing the lifting plate 3 to the fixed position. The frame 2 slides downwards, and the lifting plate 3 moves the tension sensor 5 and the connecting rod 16 connected to it downwards, causing the sliding plate 6 to slide down along the sliding rod 15. The adsorption block 19 gradually approaches the magnetic chuck. When the adsorption block 19 contacts the magnetic chuck, it will attract the magnetic chuck. After the adsorption is fixed, the controller 13 controls the cylinder 4 to slowly pull the lifting plate 3 upwards. The tension sensor 5 monitors the tension on the connecting rod 16 in real time and transmits the data to the controller 13. As the tension gradually increases until the magnetic chuck separates from the adsorption block 19, the controller 13 records the maximum tension value measured by the tension sensor 5 at this time. This value is the magnitude of the magnetic chuck's adsorption force, which is used to determine whether the magnetic chuck's adsorption performance meets the standard. The overall structure and operation steps are simple, and it can accurately detect the magnetic chuck's adsorption force, improving the accuracy of the detection results.
