[0025] The accompanying drawings are used to provide a further understanding of the present invention and form a part of the specification. They are used in conjunction with the embodiments of the present invention to explain the present invention, but do not constitute a limitation to the present invention. Detailed implementation manners

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative work shall fall within the protection scope of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] This embodiment is used to detect the hole positions of a hydraulic valve block. Since the hydraulic valve block is relatively heavy, it takes a lot of manpower to measure the hole positions on different surfaces of the hydraulic valve block, and safety accidents are also likely to occur when moving the hydraulic valve block. Therefore, a device that can conveniently detect the hole positions of the hydraulic valve block is needed.

[0029] As Figures 1-8 shown, this embodiment includes a hydraulic valve block detection bracket 100, a hole position positioning plate 200, a locator 300, and an electromagnetic dragging assembly 400. The hydraulic valve block detection bracket 100 is used to place the hydraulic valve block. The hole position positioning plate 200 is arranged on the hydraulic valve block detection bracket 100 to detect the hole positions of the hydraulic valve block. The locator 300 is arranged on the hole position positioning plate 200 to position the holes of the hydraulic valve block. The electromagnetic dragging assembly 400 is arranged on the hydraulic valve block detection bracket 100 to drag and rotate the hydraulic valve block.

[0030] A horizontal panel 101 is arranged on the hydraulic valve block detection bracket 100 proposed in this embodiment, and the electromagnetic dragging assembly 400 is arranged below the horizontal panel 101. Since the hydraulic valve block can be adsorbed by the electromagnetic dragging assembly 400 through a magnetic field, when the electromagnetic dragging assembly 400 moves, it can drag the hydraulic valve block towards the position of the hole position positioning plate 200, and at the same time, it can also drive the hydraulic valve block to rotate.

[0031] The hole position positioning plate 200 proposed in this embodiment includes a magnetic conductive metal panel 201, which is vertically arranged at the edge position of the horizontal panel 101. A pressing sensor 204 is arranged on the magnetic conductive metal panel 201. At the same time, the positioner 300 includes a magnetic base 301 and a plunger 302. The plunger 302 is fixedly arranged on the magnetic base 301, and the magnetic base 301 is adsorbed on the magnetic conductive metal panel 201 through its own magnetism. When the electromagnetic dragging component 400 drags the hydraulic valve block to the position of the magnetic conductive metal panel 201, if the hole position of the hydraulic valve block completely corresponds to the position of the plunger 302, the plunger 302 can be inserted into the hole position of the hydraulic valve block, and the hydraulic valve block can be attached to the magnetic conductive metal panel 201 and apply pressure to the pressing sensor 204. When the pressing sensor 204 detects the pressure, it proves that the hole position of the hydraulic valve block is accurate.

[0032] When this embodiment is specifically used, first, according to the standard hole position of the hydraulic valve block, a corresponding number of plungers 302 are adsorbed on the magnetic conductive metal panel 201 through the magnetic base 301, so that the positions of the plungers 302 correspond to the standard hole positions. Subsequently, the hydraulic valve block to be detected is placed on the hydraulic valve block detection bracket 100, and the electromagnetic dragging component 400 is used to drag the hydraulic valve block towards the magnetic conductive metal panel 201. By detecting the pressure received by the pressing sensor 204, it is judged whether the hydraulic valve block contacts the surface of the magnetic conductive metal panel 201. If the hydraulic valve block can contact the surface of the magnetic conductive metal panel 201, it proves that the plunger 302 can be inserted into the hole of the hydraulic valve block, and the hole position detection is qualified; if the hydraulic valve block cannot contact the surface of the magnetic conductive metal panel 201, it proves that there is a deviation in the hole position of the hydraulic valve block, resulting in the plunger 302 not being able to be inserted into the hole; after the detection of one surface is completed, the electromagnetic dragging component 400 can rotate the hydraulic valve block by ninety degrees to detect the hole position on the adjacent surface.

[0033] In this embodiment, the electromagnetic dragging component 400 is used to drag and rotate the hydraulic valve block, eliminating the need for manual adjustment by the operator, enabling convenient detection of multiple surfaces of the hydraulic valve block. At the same time, in this embodiment, the hole position detection is completed through the insertion fit between the plunger 302 and the hole of the hydraulic valve block. The hole positions of hydraulic valve blocks of different specifications can be detected by adjusting the number, length, and diameter of the plungers 302. It can not only detect the position of the hole, but also detect the inner diameter and depth of the hole, achieving better detection results.

[0034] The electromagnetic dragging assembly 400 proposed in this embodiment includes an adsorption assembly 401 and a dragging hydraulic cylinder 402. The adsorption assembly 401 is connected to the hydraulic rod of the dragging hydraulic cylinder 402. When the hydraulic rod of the dragging hydraulic cylinder 402 expands and contracts, it drives the adsorption assembly 401 to move. An electromagnet suction head 404 is provided on the adsorption assembly 401 for magnetically adsorbing the hydraulic valve block. At the same time, a through groove 103 is provided on the horizontal panel 101. The through groove 103 completely penetrates the upper and lower surfaces of the horizontal panel 101, and the electromagnet suction head 404 slides in the through groove 103.

[0035] When in use, this embodiment controls the dragging path of the hydraulic valve block through the cooperation of the through groove 103 and the adsorption assembly 401, so that the hydraulic valve block can accurately move to the position of the magnetically conductive metal panel 201. At the same time, by setting the through groove 103 that completely penetrates the horizontal panel 101, the electromagnet suction head 404 can directly contact the hydraulic valve block, improving the adsorption ability of the electromagnet suction head 404 to the hydraulic valve block, and further improving the dragging force of the electromagnet suction head 404 on the hydraulic valve block.

[0036] The electromagnet suction head 404 proposed in this embodiment is arranged on the adsorption assembly 401, and the adsorption assembly 401 is arranged on the hydraulic rod of the dragging hydraulic cylinder 402. When the hydraulic rod of the dragging hydraulic cylinder 402 expands and contracts, it drives the movement of the electromagnet suction head 404 through the adsorption assembly 401. The dragging hydraulic cylinder 402 is used to drive the movement of the electromagnet suction head 404 to drag the hydraulic valve block. The dragging hydraulic cylinder 402 can provide a greater thrust to ensure the dragging effect of the hydraulic valve block.

[0037] Conveyor rollers 104 are provided on the horizontal panel 101 proposed in this embodiment. The conveyor rollers 104 are symmetrically arranged on both sides of the through groove 103. At the same time, a coupling 105 is provided on the horizontal panel 101. The coupling 105 is connected to the conveyor rollers 104, and a conveyor motor 106 is provided on the coupling 105. The conveyor motor 106 is used to drive the rotation of the conveyor rollers 104 through the coupling 105, and the conveyor rollers 104 are used to carry and convey the hydraulic valve block.

[0038] When in use, the hydraulic valve block is placed on the conveyor rollers 104 in this embodiment. The conveyor rollers 104 on both sides of the through groove 103 provide symmetrical support forces for the hydraulic valve block to ensure that the hydraulic valve block remains stable. When the electromagnet suction head 404 drags the hydraulic valve block, the conveyor motor 106 drives the conveyor rollers 104 to rotate through the coupling 105. When the conveyor rollers 104 rotate, they assist the movement of the hydraulic valve block, improving the moving speed of the hydraulic valve block, and thus improving the efficiency of hole position detection.

[0039] The adsorption assembly 401 proposed in this embodiment further includes a telescopic base 405 and a tension spring 406. The electromagnet suction head 404 is arranged on the telescopic base 405. The two ends of the tension spring 406 are respectively connected to the telescopic base 405 and the electromagnet suction head 404. The tension spring 406 is used to stabilize the hydraulic valve block on the conveying roller 104.

[0040] During the specific use of this embodiment, the tension spring 406 is in a stretched state. The pulling force generated by the tension spring 406 acts on the electromagnet suction head 404. When the electromagnet suction head 404 adsorbs the hydraulic valve block, the tension spring 406 exerts a downward pulling force on the electromagnet suction head 404, thereby applying a downward pulling force on the hydraulic valve block, pressing the hydraulic valve block tightly against the conveying roller 104, ensuring that the hydraulic valve block always remains in contact with the conveying roller 104, and further stabilizing the posture of the hydraulic valve block.

[0041] A rotating motor 407 is arranged at the bottom of the telescopic base 405 proposed in this embodiment. The rotating motor 407 is used to drive the electromagnet suction head 404 and the telescopic base 405 to rotate synchronously. During the specific use, when the hole positions on one surface of the hydraulic valve block are detected, the electromagnetic dragging assembly 400 moves the hydraulic valve block away from the magnetizable metal panel 201, and then the rotating motor 407 rotates by a specified angle to make another undetected surface face the position of the magnetizable metal panel 201, so as to facilitate the detection of the hole positions on different surfaces.

[0042] The electromagnetic dragging assembly 400 proposed in this embodiment includes a dragging base 403. The adsorption assembly 401 and the dragging hydraulic cylinder 402 are arranged on the dragging base 403. The adsorption assembly 401 is slidably connected to the dragging base 403. A head connecting seat 408 is arranged at the end of the hydraulic rod of the dragging hydraulic cylinder 402. The telescopic base 405 is arranged on the head connecting seat 408. The dragging base 403 is provided to support the adsorption assembly 401.

[0043] During the specific use of this embodiment, the adsorption assembly 401 slides on the dragging base 403. The dragging base 403 supports the adsorption assembly 401, acting the weight of the hydraulic valve block on the dragging base 403, reducing the shear moment on the hydraulic rod of the dragging hydraulic cylinder 402, thereby improving the working life of the dragging hydraulic cylinder 402.

[0044] The hydraulic valve block detection bracket 100 proposed in this embodiment includes a guiding plate 102. The guiding plate 102 is arranged at a section of the horizontal panel 101 far from the magnetizable metal panel 201. A width adjustment groove 107 is arranged on the guiding plate 102. A guiding strip 108 is slidably arranged on the width adjustment groove 107. A fixing bolt 109 is arranged on the guiding strip 108. The guiding strip 108 is connected to the width adjustment groove 107 through the fixing bolt 109. The guiding strip 108 is used to guide the hydraulic valve block.

[0045] When this embodiment is specifically used, place the hydraulic valve block on the guiding plate 102. By adjusting the distance between the guiding bars 108, make the distance between the guiding bars 108 equal to the width of the hydraulic valve block. Use the fixing bolts 109 to fix the guiding bars 108 in the width adjustment slots 107. Then pass the hydraulic valve block through the space between the guiding bars 108 and push it onto the horizontal panel 101.

[0046] By providing adjustable guiding bars 108, it is applicable to hydraulic valve blocks of different sizes, ensuring that the hydraulic valve block maintains an angle when entering the horizontal panel 101, making the magnetically conductive metal panel 201 parallel to the surface of the hydraulic valve block to be detected, thereby ensuring that the plunger 302 is perpendicular to the surface of the hydraulic valve block.

[0047] The magnetically conductive metal panel 201 proposed in this embodiment is provided with a PLC controller 202. The PLC controller 202 is electrically connected to the conveying motor 106 and the rotating motor 407. The PLC controller 202 controls the operation of the conveying motor 106 and the rotating motor 407. When this embodiment is specifically used, the control of the conveying motor 106 and the rotating motor 407 is realized through the PLC controller 202, with higher control precision, faster response speed, and higher automation degree.

[0048] The pressing sensor 204 proposed in this embodiment is electrically connected to the PLC controller 202. The PLC controller 202 is used to detect the pressure signal of the pressing sensor 204, with higher detection precision. The position of the hydraulic valve block is quantified through the pressure signal of the pressing sensor 204, improving the judgment precision of the hole position detection of the hydraulic valve block.

[0049] The magnetically conductive metal panel 201 proposed in this embodiment is provided with scale dividing lines 203. The scale dividing lines 203 are used to position the magnetic base 301, facilitating the setting of the position of the magnetic base 301 according to the standard hole positions of the hydraulic valve block.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0051] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. In summary, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, creatively design structural manners and embodiments similar to this technical solution, they shall fall within the protection scope of the present invention.
