Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a needle valve disassembly and assembly tool. Background Art

[0002] The atomizer needle valve on the spray robot opens and closes thousands of times a day, which causes great wear and tear on some of the rubber parts.

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0029] Please refer to the following Figures 1 to 4 A needle valve disassembly and assembly tool according to an embodiment of the utility model is described.

[0030] like Figures 1 to 4As shown, the needle valve disassembly tool of the embodiment of the utility model includes a substrate 100, and a plurality of disassembly grooves 101 are provided on the substrate 100. The plurality of disassembly grooves 101 are arranged at intervals along the circumference of the substrate 100, and the disassembly grooves 101 penetrate the substrate 100 along the thickness direction of the substrate 100. The disassembly grooves 101 are open toward the outer edge of the substrate 100 and extend along the first direction. The disassembly groove 101 has a first clamping surface 1011 and a second clamping surface 1012. The first clamping surface 1011 and the second clamping surface 1012 have a spacing L along the second direction. The first direction, the second direction and the thickness direction of the substrate 100 are orthogonal to each other, and the spacing L of at least two disassembly grooves 101 is different.

[0031] According to the needle valve disassembly tool of the embodiment of the utility model, when the needle valve disassembly tool is used, the needle valve can be inserted into the disassembly groove 101 along the first direction, and the first clamping surface 1011 and the second clamping surface 1012 can clamp the two opposite wall surfaces of the needle valve. The staff rotates the substrate 100 to complete the disassembly and assembly of the needle valve. Since the multiple disassembly and assembly grooves 101 are arranged at intervals along the circumference of the substrate 100, and the distance L between at least two disassembly and assembly grooves 101 is different, different types of needle valves can be disassembled and assembled through the disassembly and assembly grooves 101 with different distances L. Therefore, the needle valve disassembly and assembly tool of the embodiment of the utility model integrates the disassembly and assembly grooves 101 of different sizes on one substrate 100, so that the needle valve disassembly and assembly tool can be applicable to different types of needle valves, has a wide range of applications, and has low cost.

[0032] It is understandable that if Figure 1 and Figure 2 As shown, the first clamping surface 1011 and the second clamping surface 1012 are arranged parallel to each other. The valve tip of the needle valve is provided with a first clamping surface (not shown) and a second clamping surface (not shown) on both sides along its radial direction. After the disassembly groove 101 is inserted into the valve tip of the needle valve, the disassembly groove 101 and the needle valve are in clearance fit, the first clamping surface 1011 is opposite to the first clamping surface, and the second clamping surface 1012 is opposite to the second clamping surface. When the staff rotates the substrate 100, the substrate 100 can drive the valve tip of the needle valve to rotate, thereby the valve tip of the needle valve can be disassembled from the needle valve body.

[0033] Alternatively, if Figure 1 and Figure 2 As shown, a plurality of via holes 102 are provided on the substrate 100, and one via hole 102 corresponds to one disassembly and assembly groove 101. The via hole 102 penetrates the substrate 100 along the thickness direction of the substrate 100, and one end of the disassembly and assembly groove 101 away from the opening of the disassembly and assembly groove 101 is connected to the via hole 102, and the inner diameter of the via hole 102 is larger than the distance L between the first clamping surface 1011 and the second clamping surface 1012.

[0034] It is understandable that a through hole 102 is provided inside the disassembly groove 101, and the aperture of the through hole 102 is larger than the groove spacing of the disassembly groove 101. Therefore, when the substrate 100 and the needle valve are too tightly connected and the substrate 100 cannot be pulled out, a thrust can be applied to the substrate 100 to push the needle valve into the through hole 102, and then the substrate 100 is separated along the axial direction of the needle valve. In other words, it is easier for the staff to apply a thrust to the substrate 100 than to apply a pulling force to the substrate 100, thereby making it easier to separate the needle valve from the substrate 100.

[0035] On the other hand, when there are parts interfering around the needle valve, the substrate 100 can be sleeved on the needle valve through the through hole 102, and then the needle valve can be sent into the disassembly groove 101 to disassemble the needle valve, thereby making it more convenient to disassemble the needle valve.

[0036] Of course, the aperture of the via hole 102 cannot be too large, otherwise it will affect the structural strength of the substrate 100. The via hole 102 cannot be too small, otherwise it will make it difficult for the valve tip of the needle valve to escape from the via hole 102. In the example of the present application, the inner circumference of the via hole 102 is circular, and the radius of the via hole 102 is R, 3.5mm≤R≤4mm. This makes it easy for the valve tip of the needle valve to pass through the via hole 102 without any obstacles, and will not affect the structural strength of the substrate 100.

[0037] Alternatively, if Figure 1 As shown, the connection position between at least one of the first clamping surface 1011 and the second clamping surface 1012 and the outer wall surface of the substrate 100 has a first chamfer 1031. For example, a first round chamfer is provided between the first clamping surface 1011 and the second clamping surface 1012 and the outer wall surface of the substrate 100, so that when the disassembly groove 101 is clamped into the valve tip of the needle valve, it can be guided by the first round chamfer to improve the disassembly efficiency of the needle valve.

[0038] Alternatively, if Figure 1 As shown, the connection position between at least one of the first clamping surface 1011 and the second clamping surface 1012 and the inner circumferential surface of the through hole 102 has a second chamfer 1032. For example, a second round chamfer is provided between the first clamping surface 1011 and the second clamping surface 1012 and the inner circumferential surface of the through hole 102, so that when the disassembly groove 101 is clamped into the valve tip of the needle valve, it can be guided by the second round chamfer to improve the disassembly efficiency of the needle valve.

[0039] In one example, if Figure 1 and Figure 2As shown, the plurality of disassembly and assembly grooves 101 are respectively the first groove 111, the second groove 112 and the third groove 113, the outer peripheral contour of the substrate 100 is rectangular, the first groove 111, the second groove 112 and the third groove 113 are respectively arranged on the three side surfaces of the substrate 100 along the circumference of the substrate 100, and the via 102 is arranged on at least one of the first groove 111, the second groove 112 and the third groove 113. It can be understood that the three spacings L of the first groove 111, the second groove 112 and the third groove 113 are all different, so that the needle valve disassembly and assembly tool can disassemble different types of needle valves. Since the first groove 111, the second groove 112 and the third groove 113 are respectively arranged on the three side surfaces of the substrate 100 along the circumference of the substrate 100, the layout of the plurality of disassembly and assembly grooves 101 can be made compact, which is conducive to reducing the overall size of the substrate 100.

[0040] Specifically, the through hole 102 includes a first hole 1021 and a second hole 1022. The first hole 1021 is connected to the first groove 111, and the second hole 1022 is connected to the second groove 112. The aperture of the second hole 1022 is larger than the aperture of the first hole 1021. This makes it easier to disengage the first groove 111 (the second groove 112) from the needle valve, which is beneficial to improving the disassembly and assembly efficiency.

[0041] Alternatively, if Figure 2 As shown, the spacing between the first clamping surface 1011 and the second clamping surface 1012 in the first groove 111 is L1, 3.4mm≤L1≤3.6mm. The spacing between the first clamping surface 1011 and the second clamping surface 1012 in the second groove 112 is L2, 4.9mm≤L2≤5.1mm. The spacing between the first clamping surface 1011 and the second clamping surface 1012 in the third groove 113 is L3, 14.9mm≤L3≤15.1mm. It can be understood that the first groove 111, the second groove 112 and the third groove 113 correspond to needle valves of different models, respectively. Since the spacing L between the first groove 111, the second groove 112 and the third groove 113 has a certain gradient, needle valves of different sizes can be adapted. The machining errors of the spacing between the first groove 111, the second groove 112 and the third groove 113 are all within ±0.1 mm, thereby avoiding the problem that the disassembly groove 101 and the needle valve are too tight to be pulled out, and the problem that the disassembly groove 101 and the needle valve are too loose to slip.

[0042] In some embodiments, Figure 3As shown, the substrate 100 has a thickened area 1041 and a thinned area 1042, the thickness of the thickened area 1041 is greater than the thickness of the thinned area 1042, the first groove 111 and the second groove 112 are both arranged in the thickened area 1041, and the third groove 113 is arranged in the thinned area 1042. It can be understood that the axial dimension of the clamping surface of the needle valve corresponding to the third groove 113 is relatively small. By arranging the third groove 113 at the position of the thinned area 1042, the third groove 113 can be more easily inserted into the corresponding needle valve, thereby making the disassembly and assembly of the needle valve smoother. On the other hand, by arranging the first groove 111 and the second groove 112 in the thickened area 1041, the thickness of the substrate 100 can be appropriately increased without affecting the cooperation between the first groove 111 (the second groove 112) and the needle valve, and the structural strength of the substrate 100 can be improved.

[0043] Alternatively, if Figure 3 As shown, the thickness of the substrate 100 is M, 2mm≤M≤2.5mm. For example, the substrate 100 is made of 45# steel, thereby ensuring the overall structural strength of the substrate 100 and preventing it from being deformed by external forces.

[0044] In some embodiments, Figure 4 As shown, the base plate 100 includes a first sub-plate 1051 and a second sub-plate 1052, the first sub-plate 1051 and the second sub-plate 1052 are pivotally connected, a part of the disassembly slot 101 is provided on the first sub-plate 1051, and another part of the disassembly slot 101 is provided on the second sub-plate 1052. It can be understood that the first sub-plate 1051 and the second sub-plate 1052 can be connected by a pivot, and when the needle valve disassembly tool is used, the first sub-plate 1051 and the second sub-plate 1052 can be flattened, and when the needle valve disassembly tool is not used, the needle valve disassembly tool can be folded and summarized, thereby further reducing the occupied space of the needle valve disassembly tool.

[0045] For example, a latching protrusion (not shown) is provided on one of the first sub-plate 1051 and the second sub-plate 1052, and a groove (not shown) is provided on the other. When the first sub-plate 1051 and the second sub-plate 1052 are folded, the latching protrusion can be elastically engaged in the groove to fix the first sub-plate 1051 and the second sub-plate 1052, thereby improving the stability of the first sub-plate 1051 and the second sub-plate 1052 after folding.
