[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and 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 direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0020] This embodiment is used to detect the hole positions of the hydraulic valve block. Since the hydraulic valve block is heavy, it takes a lot of manpower to measure the hole positions on different surfaces of the hydraulic valve block, and it is also easy to cause safety accidents when moving the hydraulic valve block. Therefore, a device that can conveniently detect the hole positions of the hydraulic valve block is needed.

[0021] like Figure 1-Figure 8 As shown, this embodiment includes a hydraulic valve block detection bracket 100, a hole position positioning plate 200, a positioner 300 and an electromagnetic towing assembly 400, wherein 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 for detecting the hole position of the hydraulic valve block, the positioner 300 is arranged on the hole position positioning plate 200 for positioning the holes of the hydraulic valve block, and the electromagnetic towing assembly 400 is arranged on the hydraulic valve block detection bracket 100 for towing and rotating the hydraulic valve block.

[0022] The hydraulic valve block detection bracket 100 proposed in this embodiment is provided with a horizontal panel 101, and the electromagnetic towing assembly 400 is arranged below the horizontal panel 101. Since the hydraulic valve block can be adsorbed by the electromagnetic towing assembly 400 through the magnetic field, the electromagnetic towing assembly 400 can drag the hydraulic valve block toward the position of the hole positioning plate 200 when moving, and can also drive the hydraulic valve block to rotate.

[0023] The hole positioning plate 200 proposed in this embodiment includes a magnetic metal panel 201, which is vertically arranged on the edge of the horizontal panel 101. A pressure sensor 204 is arranged on the magnetic 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. The magnetic base 301 is adsorbed on the magnetic metal panel 201 through its own magnetism. When the electromagnetic dragging component 400 drags the hydraulic valve block to the position of the magnetic 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 fit onto the magnetic metal panel 201 and apply pressure to the pressure sensor 204. When the pressure sensor 204 detects the pressure, it proves that the hole position of the hydraulic valve block is accurate.

[0024] When this embodiment is used in practice, first, according to the standard hole position of the hydraulic valve block, a corresponding number of plungers 302 are adsorbed on the magnetic metal panel 201 through the magnetic base 301, so that the position of the plunger 302 corresponds to the standard hole position, and then the hydraulic valve block to be tested is placed on the hydraulic valve block detection bracket 100, and the electromagnetic towing assembly 400 is used to tow the hydraulic valve block toward the magnetic metal panel 201, and the pressure of the press sensor 204 is detected to determine whether the hydraulic valve block contacts the surface of the magnetic metal panel 201. If the hydraulic valve block can contact the surface of the magnetic 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 metal panel 201, it proves that there is a deviation in the hole position of the hydraulic valve block, resulting in the plunger 302 being unable to be inserted into the hole; after completing the detection of one surface, the electromagnetic towing assembly 400 can rotate the hydraulic valve block ninety degrees to detect the hole position on the adjacent surface.

[0025] The present embodiment uses the electromagnetic towing assembly 400 to drag and rotate the hydraulic valve block, and no adjustment is required by the operator, so that multiple surfaces of the hydraulic valve block can be conveniently inspected. At the same time, the present embodiment completes the hole position detection through the insertion cooperation of 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 plunger 302. Not only the position of the hole can be detected, but also the inner diameter and depth of the hole can be detected, thereby achieving better detection effect.

[0026] The electromagnetic towing assembly 400 proposed in this embodiment includes an adsorption assembly 401 and a towing hydraulic cylinder 402. The adsorption assembly 401 is connected to the hydraulic rod of the towing hydraulic cylinder 402. When the hydraulic rod of the towing hydraulic cylinder 402 is extended or retracted, the adsorption assembly 401 is driven to move. The adsorption assembly 401 is provided with an electromagnet suction head 404 for adsorbing the hydraulic valve block by magnetic force. 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.

[0027] When in use, this embodiment controls the dragging path of the hydraulic valve block by cooperating with the through slot 103 and the adsorption assembly 401, so that the hydraulic valve block can be accurately moved to the position of the magnetic metal panel 201. At the same time, by setting a through slot 103 that completely penetrates the horizontal panel 101, the electromagnetic suction head 404 can come into direct contact with the hydraulic valve block, thereby improving the adsorption capacity of the electromagnetic suction head 404 on the hydraulic valve block, and further improving the dragging force of the electromagnetic suction head 404 on the hydraulic valve block.

[0028] The electromagnet suction head 404 proposed in this embodiment is arranged on the adsorption component 401, and the adsorption component 401 is arranged on the hydraulic rod of the towing hydraulic cylinder 402. When the hydraulic rod of the towing hydraulic cylinder 402 is extended or retracted, the movement of the electromagnet suction head 404 is driven by the adsorption component 401. The towing hydraulic cylinder 402 is used to drive the movement of the electromagnet suction head 404 to tow the hydraulic valve block. The towing hydraulic cylinder 402 can provide greater thrust to ensure the towing effect of the hydraulic valve block.

[0029] The horizontal panel 101 proposed in this embodiment is provided with a conveying roller 104, and the conveying roller 104 is symmetrically arranged on both sides of the through groove 103. At the same time, a coupling 105 is provided on the horizontal panel 101, and the coupling 105 is connected to the conveying roller 104. A conveying motor 106 is provided on the coupling 105. The conveying motor 106 is used to drive the rotation of the conveying roller 104 through the coupling 105. The conveying roller 104 is used to carry and convey the hydraulic valve block.

[0030] When in use, the hydraulic valve block of this embodiment is placed on the conveying roller 104. The conveying rollers 104 on both sides of the through groove 103 provide symmetrical supporting force 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 conveying motor 106 drives the conveying roller 104 to rotate through the coupling 105. When the conveying roller 104 rotates, it assists the movement of the hydraulic valve block, thereby increasing the moving speed of the hydraulic valve block and thus improving the efficiency of hole position detection.

[0031] The adsorption assembly 401 proposed in this embodiment also 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.

[0032] When this embodiment is used, the tension spring 406 is in a tensioned state. The tension 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 applies a downward tension to the electromagnet suction head 404, thereby applying a downward tension to the hydraulic valve block, and the hydraulic valve block is tightly attached to the conveying roller 104, ensuring that the hydraulic valve block always maintains contact with the conveying roller 104, thereby stabilizing the posture of the hydraulic valve block.

[0033] The telescopic base 405 proposed in this embodiment is provided with a rotating motor 407 at the bottom, and the rotating motor 407 is used to drive the electromagnet suction head 404 and the telescopic base 405 to rotate synchronously. In specific use, after completing the hole position detection of one surface of the hydraulic valve block, the electromagnetic dragging assembly 400 moves the hydraulic valve block away from the magnetic metal panel 201, and then the rotating motor 407 rotates a specified angle to make the other undetected surface face the position of the magnetic metal panel 201, so as to facilitate the detection of the hole positions on different surfaces.

[0034] The electromagnetic towing assembly 400 proposed in this embodiment includes a towing base 403, the adsorption assembly 401 and the towing hydraulic cylinder 402 are arranged on the towing base 403, the adsorption assembly 401 is slidably connected to the towing base 403, the end of the hydraulic rod of the towing hydraulic cylinder 402 is provided with an end connecting seat 408, the telescopic base 405 is arranged on the end connecting seat 408, and the towing base 403 is provided to support the adsorption assembly 401.

[0035] When this embodiment is used, the adsorption assembly 401 slides on the towing base 403, and the towing base 403 supports the adsorption assembly 401, so that the weight of the hydraulic valve block acts on the towing base 403, reducing the shear torque on the hydraulic rod of the towing hydraulic cylinder 402, thereby increasing the service life of the towing hydraulic cylinder 402.

[0036] The hydraulic valve block detection bracket 100 proposed in this embodiment includes a guide plate 102, which is arranged on a section of the horizontal panel 101 away from the magnetic metal panel 201, and a width adjustment groove 107 is provided on the guide plate 102, and a guide bar 108 is slidably provided on the width adjustment groove 107, and a fixing bolt 109 is provided on the guide bar 108. The guide bar 108 is connected to the width adjustment groove 107 by the fixing bolt 109, and the guide bar 108 is used to guide the hydraulic valve block.

[0037] When this embodiment is used, the hydraulic valve block is placed on the guide plate 102, and the distance between the guide bars 108 is adjusted to be equal to the width of the hydraulic valve block. The guide bars 108 are fixed in the width adjustment grooves 107 using fixing bolts 109, and then the hydraulic valve block is passed through the guide bars 108 and pushed onto the horizontal panel 101.

[0038] By setting an adjustable guide strip 108, it is suitable for hydraulic valve blocks of different sizes, ensuring that the hydraulic valve block maintains an angle when entering the horizontal panel 101, so that the magnetic metal panel 201 is parallel to the surface of the hydraulic valve block to be tested, thereby ensuring that the plunger 302 remains vertical to the surface of the hydraulic valve block.

[0039] The magnetic conductive metal panel 201 proposed in this embodiment is provided with a PLC controller 202, and 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 used specifically, the control of the conveying motor 106 and the rotating motor 407 is realized through the PLC controller 202, and the control accuracy is higher, the response speed is faster, and the degree of automation is higher.

[0040] The pressure sensor 204 proposed in this embodiment is electrically connected to the PLC controller 202, and the PLC controller 202 is used to detect the pressure signal of the pressure sensor 204, with higher detection accuracy. The position of the hydraulic valve block is quantified by the pressure signal of the pressure sensor 204, thereby improving the judgment accuracy of the hydraulic valve block hole position detection.

[0041] The magnetic conductive metal panel 201 proposed in this embodiment is provided with scale division lines 203, and the scale division lines 203 are used to position the magnetic base 301, so as to facilitate setting the position of the magnetic base 301 according to the standard hole position of the hydraulic valve block.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
