Description

Technical Field

[0001] This utility model relates to the photovoltaic field, specifically to an auxiliary measuring tool for the thickness of the staggered and small parallel section grooves of a photovoltaic extrusion die. Background Technology

[0002] The lower die slot of an aluminum alloy extrusion die is a critical installation dimension and is a mandatory inspection item upon delivery. However, in some actual structures, two measuring surfaces, such as... Figure 2 The test surfaces I201 and II202 shown are parallel to each other, but they are arranged in an alternating pattern, forming an "alternating and small parallel segment groove". This results in the two small parallel segments not being at the same horizontal level, making it extremely difficult or inaccurate to measure the normal distance (corresponding to the groove thickness) between them using a vernier caliper. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an auxiliary measuring tool for the thickness of the staggered and small parallel section grooves of a photovoltaic extrusion die.

[0004] According to this utility model, an auxiliary measuring fixture for measuring the thickness of the staggered and small parallel sections of a photovoltaic extrusion die is provided. This fixture is used to assist in measuring the thickness of the groove of the photovoltaic extrusion die, which corresponds to the normal distance between the measured surfaces I and II, which are parallel to each other on both sides of the main body of the photovoltaic extrusion die. The measuring fixture includes: a main block and a protruding block I disposed on the main block. The main block has: a fixed surface I for planar engagement with the measured surface II, and a fixed surface II for planar support on the upper surface of the main body. The protruding block I has: an extended measuring surface that is parallel to the fixed surface I and extends at a set length offset, and a recessed surface that is on the same plane as the fixed surface II.

[0005] Preferably, fixed surface I is perpendicular to fixed surface II, and the sunken surface is perpendicular to the extended measuring surface.

[0006] Preferably, on the rectangular plate-shaped main body, a notched corner is formed by fixing surface I and fixing surface II being adjacent to each other.

[0007] Preferably, the perpendicular feet of fixed surface I and fixed surface II are provided with inner rounded corners, wherein the perpendicular feet are the centers of the circles.

[0008] Preferably, the extended measuring surface is located on the other side of the main body that is parallel to the fixed surface I.

[0009] Preferably, a handle is also provided on the protruding block II on the main body, where a fixing surface II is formed.

[0010] Preferably, the handle is vertically centered on the upper plane of the main body opposite to the fixed surface II.

[0011] Preferably, the protruding block I is fixedly mounted to or integrally formed on the main body block.

[0012] Preferably, the protruding block I is rectangular in shape.

[0013] The beneficial effects of this utility model are: by using this measuring fixture, the normal distance between two surfaces that is difficult to measure can be transformed into a plane that is easy to measure, and then a fixed value can be subtracted, making the measurement convenient and accurate.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings. Attached Figure Description

[0019] This utility model provides an auxiliary measuring fixture 100 for measuring the thickness of the groove of a photovoltaic extrusion die with staggered and small parallel sections. It is suitable for measuring the groove thickness of the lower die 200 of the extrusion die (corresponding to the photovoltaic extrusion die). The thickness corresponds to the normal distance between the measured surfaces I 201 and II 202, which are parallel to each other on both sides of the main body 203 of the lower die 200.

[0020] More specifically, such as Figure 2 As shown, the surfaces to be measured, I201 and II202, are parallel and staggered vertically at a predetermined offset distance. When projected onto the virtual left side, they do not intersect. Figure 2 In the main view, the upper and lower continuous parts of the test surface I201 and the test surface II202 are respectively arc-shaped or line segments that are not parallel to the test surface I201 and the test surface II202.

[0021] The measuring fixture 100 includes: a main body block 101, a protruding block I 102, and a handle 110.

[0022] The main body block 101 has the following: a fixing surface I104 for planar engagement with the surface to be measured II202, and a fixing surface II105 for planar support on the upper surface of the main body 203.

[0023] The protruding block I 102 is fixedly mounted or integrally formed on the main body block 101, and has the following: an extended measuring surface 103 that is parallel to the fixed surface I 104 and extends at a set length offset, and a sunken surface 107 that is on the same plane or the same horizontal plane as the fixed surface II 105.

[0024] Thus, when the fixed surface II 105 is overlapped on the upper surface of the main body 203, and the fixed surface I 104 is fixed to the surface II 202 to be measured by plane engagement, the extended measuring surface 103 will be parallel to and directly opposite the surface I 201 to be measured based on the design of staggered extension setting length, and the sunken surface 107 is on the same plane as the upper surface of the main body 203, so that it can be easily measured with vernier calipers. By subtracting the corresponding distance between the extended measuring surface 103 and the fixed surface I 104 from the measured value, the normal distance between the surface I 201 to be measured and the surface II 202 to be measured can be obtained.

[0025] In some embodiments, the test surface I 201 and the test surface II 202 are perpendicular to the upper surface of the main body 203. Correspondingly, the fixed surface I 104 is perpendicular to the fixed surface II 105, and the sunken surface 107 is perpendicular to the extended measurement surface 103.

[0026] An inner radius 108 is provided at the perpendicular foot of the fixed surface I104 and the fixed surface II105, with the perpendicular foot being the center of the circle. This can reduce or eliminate the influence of burrs or abnormal protrusions on the mold edge on the measurement results during use.

[0027] In some embodiments, on the rectangular plate-shaped body 203, the fixing surface I 104 and the fixing surface II 105 are adjacent to each other to form a notched corner; on the protruding block II 106 on which the fixing surface II 105 is formed (at this time, the fixing surface II 105 is the lower surface of the protruding block II 106), for example on the upper plane 109 opposite to the fixing surface II 105, a handle 110 for operation is provided; the extended measuring surface 103 is located on the other side parallel to the fixing surface I 104.

[0028] In some embodiments, the measuring fixture 100 is machined as a single piece, made of tool steel, and the protruding block I 102 is generally rectangular. Figure 1 As shown, protruding block I102 is located at the lower left corner of the main body block 101 from the main viewpoint. Of course, it is not limited to this; the two can also be combined by means of screw fixing, slot engagement, etc.

[0029] In some embodiments, the handle 110 is vertically centered on the upper plane 109 for easy access to the measuring fixture 100.

[0030] <Example of Measurement Method>

[0031] The initial purpose was to measure the distance between the surface to be measured, I201 and II202, but the vernier caliper could not measure it directly.

[0032] Hold the handle 110 of the measuring fixture 100 so that the fixed surface I 104 is close to the surface to be measured II 202, and the fixed surface II 105 is close to the upper surface of the body 203 of the lower die 200 of the extrusion mold. At this time, the recessed surface 107 and the upper surface of the body 203 of the lower die are on the same horizontal plane.

[0033] The distance between the surface to be measured, I201, and the extended measuring surface, 103, is measured as a mm using vernier calipers. The measuring fixture 100 is removed, and the distance between the extended measuring surface, 103, and the fixed surface, I104, is measured as b mm using vernier calipers. The distance between the surface to be measured, I201, and the surface to be measured, II202, is the groove thickness of the lower die 200 of the extrusion mold, which is (ab) mm.

[0034] <Example 1>

[0035] The measuring fixture 100 is made of tool steel, specifically W18Cr4V high-speed steel.

[0036] The width of the fixed surface I104 is 2 (±0.05) mm.

[0037] The distance between the extended measuring surface 103 and the fixed surface I 104 is a fixed value, taking exactly 10mm as an example.

[0038] The perpendicularity between fixed surface I104 and fixed surface II105 is 90 (±0.02)°.

[0039] The center of the inner fillet 108 is the foot of the perpendicular between fixed surface I 104 and fixed surface II 105, and the diameter is 3.5 (±0.05) mm.

[0040] The parallelism accuracy between the fixed surface I104 and the extended measuring surface 103 is 0.002 mm.

[0041] Other dimensions do not affect the measurement or measurement accuracy, and will not be described in detail.

[0042] Holding handle 110, place fixed surface I 104 close to the surface to be tested II 202, and fixed surface II 105 close to the upper surface of the main body 203. At this time, the sinking surface 107 and the upper surface of the main body 203 of the extrusion die 200 are on the same horizontal plane.

[0043] The distance between the measured surface I201 and the extended measuring surface 103 was measured to be 16.55 mm using vernier calipers.

[0044] Measure the distance between the test surface I201 and the test surface II202, that is, the groove thickness of the lower die 200 of the extrusion die = 16.55 - 10 = 6.55 mm.
