Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of poles, and in particular to a pole torque test structure and a device. Background Art
[0002] The mainstream square large-cell cover poles on the market usually adopt an injection molding fastening structure. They are usually cylindrical in shape and have a smooth surface. The pole torque test fixture cannot be fixed. The cover manufacturers generally adopt the method of drilling a single hole in the pole and then tapping the thread: drill a hole of a certain depth on the pole terminal with a fixed diameter drill bit, then thread the hole, and then test the torque with a screw combined with a torque wrench. Since the pole material is mostly aluminum, which is soft, the drilling and tapping test method makes the thread easy to wear and the supporting strength is insufficient. The actual test cannot accurately measure the pole torque. At the same time, with the widespread application of minimalist structures, the thickness of the pole is generally reduced to less than 5mm, and the thickness of the pole no longer supports the drilling and tapping of the pole. As for the pole sleeve fixture method, since the shape of the pole is usually cylindrical, the sleeve fixture is not subjected to force and the sleeve fixture cannot be set. Utility Model Content

[0027] like Figure 1 As shown, an embodiment of the utility model discloses a pole torque test structure, which is applied to a pole terminal 1. For example, the pole terminal 1 is a cylindrical pole terminal on a cell cover. The pole torque test structure includes a force-bearing structure 2 and a force-bearing block 3. Specifically:
[0028] The force-bearing structure 2 is provided on the pole terminal 1, and a force-bearing point is formed on the circumference of the pole terminal 1. The force-bearing structure 2 is a groove or a perforation. The force-bearing block 3 includes a first connecting portion 31 and a first force-bearing portion 32. The shape of the first connecting portion 31 is adapted to the shape of the force-bearing structure 2. The first connecting portion 31 is inserted into the force-bearing structure 2 to limit the circumferential movement of the force-bearing block 3. The first force-bearing portion 32 has a force-bearing point on the circumference.
[0029] Among them, first, a force point is formed on the circumference of the pole terminal 1 through the force structure 2, and then in order to adapt to common torque test pieces, such as torque test wrenches, a force block 3 is matched according to the force structure 2, and the shape of the first connecting part 31 of the force block 3 is adapted to the shape of the force structure 2, and the first connecting part 31 is inserted into the force structure 2 to limit the circumferential movement of the force block 3, and the first force part 32 of the force block 3 has a force point on the circumference, so that the torque test piece is connected to the first force part 32 of the force block 3, and then the torque test of the pole is completed. The pole torque test structure solves the problems that the pole material is relatively soft and the threaded structure is insufficiently stressed, the pole thickness is too thin to tap the thread, and the cylindrical pole has no force point and cannot support the sleeve clamp.
[0030] It should be noted here that the grooves and perforations refer to grooves or perforations with smooth inner wall surfaces, which are different from the existing drilling and tapping, and the plug-in connection refers to the first connecting portion 31 of the force-bearing block 3 being inserted into the force-bearing structure 2 along the vertical direction of the upper surface of the pole terminal 1, which is different from the existing threaded connection.
[0031] In some embodiments, such as Figure 2 As shown, the force-bearing structure 2 is a polygonal groove opened on the upper surface of the pole terminal 1 or a polygonal through-hole penetrating the pole terminal 1. Figure 3 As shown, the first connecting portion 31 is a polygonal column, wherein the polygon has a force point, and the polygon can be three sides, four sides or any number. For example, the polygon is a square, rectangle, cross, straight or hexagonal shape, etc. The shape here is only an example and is not intended to limit the present application.
[0032] In some other embodiments, Figure 1 As shown, the force-bearing structure 2 is at least two grooves opened on the upper surface of the pole terminal 1 or at least two through-holes penetrating the pole terminal 1. Accordingly, the first connecting portion 31 is at least two columns, wherein at least two grooves or through-holes have force-bearing points, and the at least two can be two, three or any number. For example, the groove is a circular groove, and the column is a cylinder. The circular shape here is only an example and is not intended to limit the present application.
[0033] In some embodiments, the shape of the first force-bearing portion 32 may be the same as or different from the shape of the force-bearing structure 2, which is not limited herein. Figure 1 As shown, the force-bearing structure 2 is two grooves or through holes, and the first force-bearing portion 32 is a square column.
[0034] In some embodiments, when the force-bearing structure 2 is a groove, the depth of the groove on the pole is greater than or equal to 2 mm, for example, 3 mm. The 3 mm here is only an example and is not intended to limit the present application.
[0035] In some embodiments, in order to avoid the stress of the pole terminal 1 being easily damaged by the processing area of the stress-bearing structure 2 being too large, the area of the stress-bearing structure 2 accounts for 10% to 30% of the area of the upper surface of the pole terminal 1, for example, 20%. The 20% here is only an example and is not a limitation of the present application. Moreover, the stress-bearing structure 2 is located at the center of the pole terminal 1.
[0036] In some embodiments, the first connection portion 31 is tightly connected to the force-bearing structure 2 , thereby ensuring that the test result is not affected by the looseness between the force-bearing block 3 and the force-bearing structure 2 during the test.
[0037] In some embodiments, in order to ensure force transmission, the first connecting portion 31 and the first force-bearing portion 32 are on the same vertical line of the upper surface of the pole terminal.
[0038] In some embodiments, such as Figure 1 As shown, in order to adapt to the torque test pieces on the market as much as possible, the pole torque test structure also includes an adapter block 4, the adapter block 4 includes a second connecting portion 41 and a second force-bearing portion 42, the shape of the second connecting portion 41 is adapted to the shape of the first force-bearing portion 32, the second connecting portion 41 is connected to the first force-bearing portion 32 and limits the circumferential movement of the adapter block 4, the second force-bearing portion 42 has a force point in the circumferential direction, and the shape of the second force-bearing portion 42 is different from the shape of the first force-bearing portion 32, as shown in FIG. Figure 1 As shown, the first force-bearing portion 32 is a square column, and the second force-bearing portion 42 is a square groove. In addition, the connection between the second connecting portion 41 and the first force-bearing portion 32 can be plug-in or threaded, etc., which is not limited here.
[0039] In some embodiments, the force-bearing block 3 and the adapter block 4 are blocks made of rigid materials, such as non-deformable plastic or metal. The non-deformable plastic or metal here is only an example and is not intended to limit the present application.
[0040] An embodiment of the utility model discloses a pole torque testing device, including a torque testing piece and the pole torque testing structure described in the above embodiment. The pole torque testing structure is not described in detail here, wherein the torque testing piece can be connected to the first force-bearing part 32 or the second force-bearing part 42, so as to complete the torque test of the pole.
