Description

Technical Field

[0001] The present application relates to the field of detection, and in particular to a wireless magnetized magnetic material suction detection device. Background Art

[0002] Magnetic materials are an indispensable component of many electrical and electronic products. In order to meet production needs, the magnetic strength screening of magnetic materials has also become an indispensable link. Only by screening out magnetic materials with appropriate magnetic strength can the final products achieve the expected effect.

[0003] The structure of the product can refer to the Chinese patent document (201621329363.0) disclosed in a magnetic material detection device with accurate readings, which includes a handle, a moving block and a base. A fixed plate is installed under the handle, a rotating threaded rod is connected under the fixed plate, a fixed rod is arranged on the right side of the rotating threaded rod, and the fixed rod is connected to the fixed plate, a scale is printed on the fixed rod, a push rod is installed on the moving block, a guide rail is arranged above the push rod, an adjustment knob is connected to the push rod, a force meter is connected above the display screen, and a lower tray is fixed above the force meter.

[0004] In the above structure, due to the effect of the hand wheel, the moving block cannot be accurately controlled when detecting magnetism, resulting in that the position of the moving block is different each time the magnetism is measured, thus affecting the magnetism detection result.

[0005] There is no wireless magnetized magnetic material suction detection device with high-precision magnetic detection. Summary of the invention

[0006] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0007] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a wireless magnetized magnetic material suction detection device, including: a loading frame, formed with a loading cavity for loading a standard magnetic part for detecting magnetism;

[0008] A workbench, providing a work surface for placing a workpiece to be tested for magnetic properties;

[0010] A base, providing a support surface for mounting the guide post so that the base supports the guide post;

[0011] Wireless magnetizing magnetic material suction detection equipment also includes:

[0012] A clamping assembly, providing a plurality of clamping surfaces for clamping the workpiece to be tested for magnetism so as to fix the workpiece to be tested for magnetism on a work surface;

[0013] A hydraulic rod is arranged at one end of the guide column away from the base and is coaxially arranged with the guide column;

[0014] A driving assembly, used for driving the workbench to move along the axial extension direction of the guide column so that the workpiece to be measured for magnetic properties is close to the standard magnetic part;

[0015] The driving assembly includes a screw and a stepper motor, wherein the screw is threadedly connected to the workbench thread; the screw is rotated by the stepper motor so that the screw drives the workbench to move intermittently along the axial extension direction of the guide column so that the workpiece to be tested for magnetism intermittently approaches the standard magnetic part.

[0016] During the working process or installation process, due to the magnetism between the detected workpiece and the standard magnetic part, when the detected workpiece stops moving, the loading frame will move closer to the base, and the moving distance can reflect the size of the magnetic force; due to the action of the stepper motor and the lead screw, the workbench intermittently approaches the loading frame to make the measured magnetic workpiece intermittently approach the standard part; therefore, the lead screw can drive the workbench to move a distance in the direction of the loading frame and then stop to measure the first magnetic detection; then continue to move and stop to detect the magnetism again; thereby realizing multi-stage magnetic detection and improving the accuracy of magnetic detection.

[0017] Furthermore, a level is provided on the hydraulic rod, which is arranged at one end of the hydraulic rod away from the base and is fixedly connected to the bottom of the loading frame.

[0018] Further, the clamping assembly includes two guide grooves provided on the workbench and configured to be evenly arranged in the length direction of the base;

[0019] The threaded rod arranged on the workbench is constructed to be rotatably arranged on the side wall of the guide groove so that the threaded rod connects the two guide grooves.

[0020] Furthermore, the threaded rod is provided with two clamping blocks, which are constructed so that the clamping block parts are transitionally matched with the inner wall of the guide groove so that the clamping blocks can slide along the length direction of the base.

[0021] Furthermore, the portions of the threaded rod respectively located in the two guide grooves are provided with spiral grooves, and the two spiral grooves extend in a spiral shape along the extending direction of the axis of the threaded rod;

[0022] The spiral directions of the two spiral grooves are opposite to each other so that the two clamping blocks can move relatively along the axial extension direction of the threaded rod.

[0023] Furthermore, a first clamping plate is provided on the upper wall of the clamping block, and is configured to be connected to the inner bottom wall of the clamping block by a spring so that the first clamping plate can slide along the axial extension direction of the guide column.

[0024] Furthermore, two second clamping plates are provided on the side walls of the clamping block and are configured to be slidably arranged along the width direction of the base;

[0025] A plane formed by the two side walls perpendicular to the upper surface of the base and bisecting the width direction of the base is used as a longitudinal reference plane;

[0026] The two second clamping plates are symmetrically arranged on the side wall of the clamping block with respect to the longitudinal reference plane so that the two second clamping plates can move relative to each other.

[0027] Further, a second nut seat is provided on the inner upper inner wall of the clamping block, and is constructed such that a gear is provided on the side wall of the second nut seat;

[0028] Racks meshing with the gears are arranged on the two second clamping plates.

[0029] Further, a guide rod is provided on the upper wall of the clamping block and is constructed to have a thread groove that is threadably matched with the second nut seat;

[0030] One end of the guide rod away from the base protrudes from the upper end of the first clamping plate in a direction away from the base.

[0031] Furthermore, a surface formed by the two side walls perpendicular to the upper surface of the base and bisecting the length direction of the base becomes a vertical reference surface;

[0058] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0059] Reference Figure 1 The wireless magnetized magnetic material suction detection device comprises: a loading frame 1, which is formed with a loading cavity 11 for loading a standard magnetic part for detecting magnetism.

[0060] The workbench 2 provides a work surface for placing the workpiece to be tested for magnetism.

[0061] The guide column 3 is used to guide the moving direction of the workbench 2 so that the workbench 2 can slide along the axial extension direction of the guide column 3; specifically, the workbench 2 is provided with a guide hole 22 for the guide column 3 to penetrate, so that the guide column 3 is inserted into the guide hole 22 so that the guide column 3 and the guide hole 22 are coaxially arranged; a protective cover 31 is provided on the outer side of the guide column 3, and is constructed to have a sliding groove 32 for the workbench 2 to slide along the extension direction of the central axis of the guide column 3.

[0062] The base 4 provides a support surface 41 for installing the guide column 3 so that the base 4 supports the guide column 3; specifically, the bottom side wall of the guide column 3 has a thread, and the base 4 has a corresponding threaded hole, and the thread at the bottom of the guide column 3 is connected to the threaded hole so that the guide column 3 can be detachably arranged on the upper surface of the base 4.

[0063] The clamping assembly 5 provides a plurality of clamping surfaces for clamping the workpiece to be tested for magnetism so as to fix the workpiece to be tested for magnetism on the workbench.

[0064] The hydraulic rod 6 is arranged at the end of the guide column 3 away from the base 4 and is coaxially arranged with the guide column 3; specifically, the end of the hydraulic rod 6 away from the guide column 3 is fixedly connected to the loading frame 1 so that the hydraulic rod 6 drives the loading frame 1 to move along the axial direction of the guide column 3; more specifically, a force meter is also provided at the bottom of the hydraulic rod 6 to reflect the pressure exerted on the hydraulic rod 6.

[0065] The driving assembly 7 is used to drive the workbench 2 to move along the axial extension direction of the guide column 3 so that the workpiece to be measured for magnetic properties is close to the standard magnetic part.

[0066] Among them, the driving component 7 includes a screw rod 71 and a stepper motor 72, and the screw rod 71 is threadedly connected to the workbench 2; more specifically, the screw rod 71 is connected to the output shaft of the stepper motor 72 through a coupling; the screw rod 71 is rotated by the stepper motor 72 so that the screw rod 71 drives the workbench 2 to intermittently move along the axial extension direction of the guide column 3 so that the workpiece to be detected magnetically intermittently approaches or moves away from the standard magnetic part.

[0067] The level 8 provided on the hydraulic rod 6 is provided at one end of the hydraulic rod 6 away from the base 4 and is fixedly connected to the bottom of the loading frame 1; specifically, the level 8 is provided between the loading frame 1 and the hydraulic rod 6 to detect the parallelism of the loading frame 1. When the workbench 2 stops moving, the loading part will shake due to the effect of magnetism; the effect of the level 8 can reflect the stability of magnetism.

[0068] The clamping assembly 5 includes two guide grooves 51 opened on the workbench 2, which are constructed to be evenly arranged in the length direction of the base 4; a threaded rod 52 arranged on the workbench 2 is constructed to be rotatably arranged on the side wall of the guide groove 51; more specifically, a through hole is arranged between the two guide grooves 51, and the threaded rod 52 passes through the through hole and is connected to the two guide grooves 51; specifically, a handle is provided at one end of the threaded rod 52 to facilitate the staff to rotate the threaded rod 52.

[0069] The threaded rod 52 is provided with two clamping blocks 9, and the clamping blocks 9 are partially inserted into the guide groove 51 and transitionally matched with the inner wall of the guide groove 51 so that the clamping blocks 9 can slide along the length direction of the base 4; specifically, the two clamping blocks 9 are both provided with a first clamping surface 91 that contacts the workpiece to be inspected; through the setting of the two clamping blocks 9, the workpiece to be inspected can be upper-limited in the length direction of the base 4.

[0070] The parts of the threaded rod 52 respectively located in the two guide grooves 51 are provided with spiral grooves 53, and the two spiral grooves 53 extend in a spiral shape along the axis of the threaded rod 52, and the spiral directions of 53 in the two guide grooves are opposite; specifically, the first nut seat 92 is fixed at the bottom of the two clamping blocks 9, and the first nut seat 92 is threadedly matched with the two spiral grooves 53; since the spiral directions of the thread grooves are opposite, the two clamping blocks 9 move relative to each other along the axial extension direction of the threaded rod 52; in this way, the clamping of the workpiece to be inspected can be achieved.

[0071] A first clamping plate 93 is provided on the upper wall of the clamping block 9, and is constructed to be connected to the inner bottom wall of the clamping block 9 by a spring 94 so that the first clamping plate can slide along the axial extension direction of the guide column 3; specifically, the first clamping plate 93 has a second clamping surface 95 that contacts the upper end surface of the workpiece to be inspected; during inspection, the worker pulls the first clamping plate 93 to move away from the base 4 so that the second clamping surface 95 of the first clamping plate 93 contacts the upper end surface of the workpiece to be inspected, thereby achieving the limitation of the workpiece to be inspected in the axial extension direction of the guide column 3; when detecting magnetism, the displacement of the workpiece to be inspected due to the influence of the magnetic force affects the detection result.

[0072] Two second clamping plates 96 are provided on the side walls of the clamping block 9, and are constructed to be slidably arranged along the width direction of the base 4; the surface formed by the two side walls perpendicular to the upper surface of the base 4 and bisecting the width direction of the base 4 becomes the longitudinal reference plane; the two second clamping plates 96 are symmetrically arranged on the side walls of the clamping block 9 with respect to the longitudinal reference plane so that the two second clamping plates 96 can move relative to each other; specifically, the two second clamping plates 96 abut against the side edges of the workpiece to be inspected so that the workpiece to be inspected is limited in the width direction of the base 4.

[0073] The clamping block 9 has a cavity inside; a second nut seat 97 is set at the upper end of the inner wall, and the second nut seat 97 is rotatably set in the clamping block 9; a gear 99 is set on the side wall of the second nut seat 97; racks 98 meshing with the gear 99 are set on the two second clamping plates 96; specifically, the gear 99 is meshed with the racks 98 on the two second clamping plates 96, so rotating the gear 99 can realize the relative movement of the two racks 98, thereby making the two clamping plates closer to or farther away from each other.

[0074] A guide rod 10 is provided on the upper wall of the clamping block 9, and is constructed to have a threaded groove that threadably cooperates with the second nut seat 97; the end of the guide rod 10 away from the base 4 protrudes at the upper end of the first clamping plate 93 in a direction away from the base 4 to form a handle 101; specifically, since the guide rod 10 is provided with a threaded groove that engages with the nut seat, the second nut seat 97 can be rotated by simply pulling the guide rod 10; and when clamping the workpiece to be inspected, it is necessary to pull the first clamping plate 93. Therefore, when the first clamping plate 93 is pulled, the two second clamping plates 96 can be moved relative to each other to facilitate the clamping of the workpiece to be inspected.

[0075] The surface formed by the two side walls perpendicular to the upper surface of the base 4 and bisecting the base 4 in the length direction becomes the vertical reference plane; the two groups of clamping components 5 are symmetrically arranged on the upper surface of the workbench 2 relative to the vertical reference plane.
