Description

Technical Field

[0001] The invention relates to an electromagnetic chuck performance detection technology, and in particular to an electric permanent magnetic chuck comprehensive performance testing device and a use method thereof. Background Art

[0002] The electromagnetic chuck is a common energized adsorption magnet device in many modern factories or metal processing. By energizing the electromagnetic chuck, it generates a large magnetic force, which is used to transport goods or adsorb metal parts, thereby achieving the effect of transporting or fixing metal parts for easy processing. During the production of existing electromagnetic chucks, in order to ensure that the electromagnetic chucks have good performance and meet the standards, it is usually necessary to conduct a comprehensive performance test on the electromagnetic chuck, so a comprehensive performance test device for the electromagnetic chuck is needed.

[0003] A Chinese invention patent with publication number CN115327455B discloses an electromagnetic chuck comprehensive performance test device and a method for using the same. The electromagnetic chuck comprehensive performance test device and the method for using the same are provided with a movable clamping block. When the device is in use, the main body clamping sliding seat is first directly installed on the outside of the positioning guide rod to ensure the stability of the device. The sliding groove can effectively move along the outside of the positioning guide rod to achieve the effect of position adjustment. An electric push rod is embedded on the outside to provide the movable clamping block at the output end with the ability to move. The piston rod at the output end of the electric push rod can be driven by a driving motor to perform telescopic adjustment, which will drive the inner movable clamping block to concentrate on clamping the electromagnetic chuck. At the same time, the fixed position of the electromagnetic chuck can be determined according to the telescopic length of the piston rod. The device has better flexibility and does not require manual adjustment and clamping by the staff, which greatly reduces the difficulty of the staff's work. At the same time, it is convenient to fix electromagnetic chucks of different shapes and sizes, thereby increasing the flexibility of the device.

[0004] When the existing equipment is in use, the surface of the workpiece being tested may be uneven, resulting in uneven contact area when the load is applied, making the workpiece extremely easy to fall off during detection, and the contact area with the workpiece is small, resulting in low accuracy of the test results. At the same time, the installation of the suction cup or the load applying device is unstable, which may cause uneven load application, resulting in abnormal test results due to uneven contact of the workpiece during detection. Therefore, a comprehensive performance testing device for an electric permanent magnetic suction cup and a method for using the same have been developed. Summary of the invention

[0039] Embodiment 1:

[0040] See also Figure 1-Figure 8 A device for testing the comprehensive performance of an electric permanent magnetic chuck comprises a base 1, a support column 11 is arranged at the upper end of the base 1, a detection member 12 is arranged at the upper end of the support column 11, and the adsorption state is monitored by the detection member 12.

[0041] In this solution, the detection member 12 is a device with a monitoring function such as a sensor, and is connected to an external control device, so that the state of the suction cup can be checked in real time when the workpiece is measured.

[0042] Furthermore, a column 13 is provided at the upper end of the base 1 and on one side of the support column 11, a fixing plate 14 is provided at the upper end of the column 13, a driving member 15 is provided at the upper end of the fixing plate 14, and an output end of the driving member 15 passes through and extends to the lower end of the fixing plate 14, and a limiting component 2 is provided at the output end of the driving member 15, and the suction cup is fixed by the limiting component 2, and a power member 17 is provided at the lower end of the inner cavity of the base 1.

[0043] Specifically, the driving member 15 and the power member 17 are both devices with telescopic functions such as electric telescopic rods, and are connected to an external control device, so that when the driving member 15 is started, it can synchronously drive the limit assembly 2 set at its output end to move. Since a suction cup is clamped at the lower end of the limit assembly 2, it also provides power for the movement of the suction cup.

[0044] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

[0045] Furthermore, the calibration component 3 is mounted in the inner cavity of the base 1 and is used to calibrate the object before adsorption.

[0046] Among them, the calibration component 3 includes a fixed block 31 connected to the power part 17, and docking blocks 32 are provided at both ends of the fixed block 31. At the same time, a first movable plate 33 is provided at one end of the two docking blocks 32 away from each other, and a second movable plate 34 is slidably installed on one side of the docking block 32 and located above the first movable plate 33, and a telescopic part 331 is provided between the first movable plate 33 and the second movable plate 34.

[0047] In this embodiment, when the power part 17 is started, it can synchronously drive the entire calibration component 3 to move up and down, so that the angle of the workpiece placed on the upper end thereof can be adjusted so that the upper end of the workpiece is parallel to the suction cup, and then when the suction cup adsorbs the workpiece, it ensures that the surface of the tested workpiece is flat, so as to reduce the uneven load caused by the uneven surface, which may lead to abnormal detection results.

[0048] At the same time, the telescopic member 331 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the telescopic member 331 is started, it can drive the second movable plate 34 arranged at its output end to move, thereby increasing the distance between the first movable plate 33 and the second movable plate 34, thereby facilitating the rotation of the ball 36.

[0049] Furthermore, through holes 35 are provided at both ends of the first movable plate 33 and the second movable plate 34, and the through holes 35 are connected to the outside, and a sphere 36 is provided between two adjacent through holes 35, and a movable rod 37 is provided on the outer surface of the sphere 36, and the upper end of the movable rod 37 passes through and extends to the outside of the through hole 35, and a connecting block 38 is provided on the upper end of the movable rod 37, and a supporting plate 39 is rotatably installed on the upper end of the connecting block 38, and the adsorbed object is supported by the supporting plate 39. The upper end of the supporting plate 39 passes through and extends to the upper end of the base 1.

[0050] Specifically, when the first movable plate 33 is separated from the second movable plate 34, the ball 36 cooperates with the movable rod 37 arranged on its outer surface to drive the connecting block 38 to move. Since the end of the connecting block 38 is connected to the support plate 39, when the workpiece is placed on the support plate 39, the limiting component 2 moves downward to make the workpiece in a horizontal state, and then the telescopic part 331 cooperates to restore the second movable plate 34 to its initial position, and then the ball 36 is tightly fixed, thereby ensuring that the workpiece is stable before adsorption.

[0051] A baffle is provided at the upper end of the base 1, and one side of the baffle is in contact with the upper end of the workpiece, so that the suction cup can stretch the workpiece when it is activated, thereby accurately testing the adsorption performance, and the workpiece can be protected by the baffle to avoid damage when it is separated from the suction cup.

[0052] Furthermore, the limiting assembly 2 includes a clamping block 21 connected to the driving member 15 , and limiting blocks 22 are arranged at both ends of the clamping block 21 .

[0053] A sliding rod 23 is slidably mounted on the lower end of the clamping block 21, and a positioning plate 24 is symmetrically arranged on the outer surface of the sliding rod 23. A sliding groove 241 is arranged on one side of the positioning plate 24, and a sliding rod 242 is slidably mounted on the inner wall of the sliding groove 241, and the outer surface of the sliding rod 242 is fitted with one side of the sliding rod 23.

[0054] In this embodiment, a guide groove is provided at the lower end of the clamping block 21, and the inner wall of the guide groove is slidably connected to the outer surface of the upper end of the sliding rod 23, and at the same time cooperates with the limit block 22 to limit the sliding rod 23 to prevent the sliding rod 23 from detaching from the clamping block 21.

[0055] A positioning plate 24 is rotatably mounted on the outer surface of the sliding rod 23 . The entire positioning plate 24 is limited by a sliding groove 241 and a sliding rod 242 on the positioning plate 24 , thereby preventing the positioning plate 24 from rotating in a large range around the connection with the sliding rod 23 .

[0056] At the same time, a torsion spring is provided at the rotation connection between the sliding rod 23 and the positioning plate 24, which is used to support the positioning plate 24, so that the positioning plate 24 is always in a taut state and drives the positioning rod 26 to move downward.

[0057] Furthermore, a U-shaped block 25 is rotatably mounted on one side of the positioning plate 24 and below the sliding groove 241 , and the inner wall of the U-shaped block 25 is in contact with the outer surface of the sliding rod 23 .

[0058] A positioning rod 26 is rotatably mounted at the edge of one side of the positioning plate 24 , an adjusting rod 27 is rotatably mounted at the middle position of one side of the positioning rod 26 , and a pressing block 261 is provided at the lower end of the positioning rod 26 .

[0059] Specifically, when the clamp 29 is placed between the pressing block 261 and the fixing rod 28, the positioning plate 24 is driven to rotate around the connection with the sliding rod 23 by the force of the torsion spring, and is limited by the slide groove 241, thereby driving the positioning rod 26 to move downward. Since the pressing block 261 is provided at the lower end of the positioning rod 26, the pressing block 261 cooperates with the fixing rod 28 to tightly fix the clamp 29, ensuring that the test device and its components are installed firmly and avoiding uneven load distribution caused by unstable installation.

[0060] Furthermore, one end of the adjusting rod 27 away from the positioning rod 26 is rotatably connected to the lower end of the sliding rod 23 , and the middle position of the adjusting rod 27 is rotatably connected to one side of the U-shaped block 25 .

[0061] A fixing rod 28 is disposed at the lower end of the U-shaped block 25 , and a clamping plate 29 is disposed between the fixing rod 28 and the pressing block 261 .

[0062] Specifically, by fitting the inner wall of the U-shaped block 25 with the protrusion on the sliding rod 23, the U-shaped block 25 is stably located between the two positioning plates 24, and when the positioning plates 24 rotate around the sliding rod 23, the angle of the lower end of the U-shaped block 25 can be slightly adjusted to make it more suitable for the current scene.

[0063] Since the sliding rod 23 is connected to the U-shaped block 25 and the positioning rod 26 via the adjusting rod 27 , when the positioning plate 24 rotates, the positioning rod 26 is pushed to move downward and the clamping plate 29 is fixed.

[0064] Embodiment 2:

[0066] S1. Fix the permanent magnetic chuck on the test bench and ensure that it is firmly connected to the load application device;

[0067] S2. Place the object to be tested on the test bench and calibrate the workpiece to ensure that the object is accurately docked with the suction cup;

[0068] S3. Gradually apply the load until the adsorption force of the permanent magnetic chuck reaches its limit, record the change of the adsorption force through the sensor, and record the maximum adsorption force value.

[0069] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
