Description

Technical Field

[0001] This utility model relates to the technical field of profile testing equipment, specifically to a universal testing equipment for the straightness and torsion of magnesium-aluminum alloy products. Background Technology

[0002] Existing equipment for testing the straightness and torsion of magnesium-aluminum alloy products typically uses platform testing. When it is necessary to test irregularly shaped profiles, special inspection tools need to be made. Moreover, when the shape and size of the profiles change, special inspection tools need to be redesigned, made, and calibrated. During use, accuracy checks need to be performed regularly, which is too costly. Utility Model Content

[0003] To address the technical problem that the straightness and torsion testing of magnesium-aluminum alloy products requires specialized inspection tools, which are too costly, this utility model provides a universal inspection device for the straightness and torsion of magnesium-aluminum alloy products.

[0004] The technical solution is as follows:

[0005] This application relates to a universal testing device for the straightness and torsion of magnesium-aluminum alloy products, including a tooling mounting platform. Two parallel mounting seats are slidably mounted on the tooling mounting platform. Each mounting seat is equipped with a testing roller. The two testing rollers are arranged side by side in a horizontal direction, and their extension direction is perpendicular to the sliding direction of the mounting seats. Each testing roller can rotate along its respective axis under the drive of a corresponding first driving device. The two mounting seats can slide under the drive of a second driving device, thereby causing the two testing rollers to move closer or further apart.

[0006] The above-mentioned universal testing equipment for straightness and torsion of magnesium-aluminum alloy products uses a line contact between the testing roller and the test object, replacing the previous surface contact testing method. Straightness and torsion are tested by observing and measuring the gap between the test object and the testing roller. The distance between the two testing rollers can be adjusted according to the test object, and the testing rollers can rotate along their respective axes. It is applicable to almost all cross-sectional shapes of magnesium-aluminum alloy products, has high versatility, avoids the use of special inspection tools, and greatly reduces costs.

[0007] In some embodiments, the second driving device includes a first link that can slide along the tooling mounting platform under the drive of the translational driving assembly and at least one set of link assemblies. The first link is arranged parallel between two mounting seats, and the sliding direction of the first link is parallel to the axis of the detection roller. Each link assembly includes two second links arranged opposite to each other on both sides of the first link. The inner ends of the second links are hinged to the first link, and the outer ends of the second links are respectively hinged to the corresponding mounting seats. The outer ends of the second links are respectively mounted on the tooling mounting platform through corresponding linear sliding assemblies. The linear sliding assemblies all extend in the horizontal direction and are perpendicular to the first link.

[0008] In some embodiments, the linear sliding assembly includes a groove formed on the tooling installation platform and a sliding engagement component that slides with the groove. The grooves extend horizontally and are perpendicular to the first connecting rod. The sliding engagement components are respectively disposed at the outer ends of the corresponding second connecting rods, and the upper ends of each sliding engagement component are respectively hinged to the corresponding mounting base.

[0009] In some embodiments, the upper surface of the second link protrudes to form support protrusions that are adapted to the corresponding mounting seats. The bottom surface of each mounting seat is slidably supported on the top surface of the corresponding support protrusion, and each sliding fitting is integrally formed on the outer end of the corresponding support protrusion.

[0010] In some embodiments, there are two sets of the linkage assembly, with the two sets of linkage assemblies respectively located at both ends of the first linkage.

[0011] In some embodiments, the translation drive assembly includes a lead screw extending in the same direction as the first connecting rod. A lead screw mating seat is provided on the tooling mounting platform. A lead screw connecting seat is connected to one end of the first connecting rod near the lead screw mating seat. The inner end of the lead screw is rotatably connected to the lead screw connecting seat. The lead screw is threaded through the lead screw mating seat and forms a lead screw nut kinematic pair with the lead screw mating seat.

[0012] In some embodiments, each mounting base includes a base plate and two rotating shaft mounting bases respectively mounted at both ends of the base plate. Each first drive device includes a rotating shaft and a rocker arm fixedly connected to one end of the rotating shaft. Both ends of each rotating shaft are rotatably mounted on the corresponding rotating shaft mounting base. The detection rollers are synchronously rotated and fitted onto the corresponding rotating shafts.

[0013] In some embodiments, a plurality of flatness inspection modules are also included. Each flatness inspection module is detachably mounted on a mounting base. Each flatness inspection module has a mounting notch at its bottom. The bottom of the mounting notch is an arc-shaped structure adapted to the detection roller. The bottom surface of each flatness inspection module is supported on the upper surface of the corresponding mounting base, and each detection roller passes through the corresponding mounting notch. The upper surfaces of each flatness inspection module are all located on the same horizontal plane.

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0021] like Figures 1 to 5 As shown, a general-purpose testing device for straightness and torsion of magnesium-aluminum alloy products mainly includes a tooling mounting platform 1, a mounting base 2, a testing roller 3, a first driving device 4, and a second driving device 5.

[0022] like Figure 1 and Figure 2 As shown, the tooling installation platform 1 is a stable, high-load-bearing rectangular frame structure. Its upper surface is a horizontal mounting platform, and its lower support legs are equipped with lockable casters 1a. The tooling installation platform 1 adopts a movable structure, making it more flexible and convenient to use. It can realize online rapid inspection of the straightness and torsion of magnesium-aluminum alloy products on the production line or in the warehouse, and the inspection accuracy will not change after movement, without the need for readjustment or calibration.

[0023] like Figure 2As shown, the second drive device 5 mainly includes a first connecting rod 5d, a connecting rod assembly, a linear sliding assembly, and a translational drive assembly. The second drive device 5 can adopt various structures such as a gear and rack mechanism or a worm gear mechanism, and can be controlled electrically or manually. In this embodiment, the second drive device 5 adopts a connecting rod and manual control method, which saves costs and is flexible in use.

[0024] The linear sliding assembly can take various forms such as slide rails, slide tables, or slide grooves. In this embodiment, the linear sliding assembly includes a slide groove 1b opened on the tooling installation platform 1 and a sliding mating part 5e1 that slides with the slide groove 1b. The slide groove 1b is a strip hole opened on the tooling installation platform 1, which is simple, reliable, easy to process, and low in cost.

[0025] The first connecting rod 5d is slidably mounted on the tooling mounting platform 1. Specifically, the bottom surfaces of both ends of the first connecting rod 5d are integrally formed with downwardly extending pins. The tooling mounting platform 1 has slotted holes that are adapted to the corresponding pins. The pins of the first connecting rod 5d can be slidably mounted in the corresponding slotted holes. The extending direction of the slotted holes is the same as the extending direction of the first connecting rod 5d.

[0026] The translation drive assembly includes a lead screw 5a extending in the same direction as the first connecting rod 5d. A lead screw mating seat 5b is provided on the tooling mounting platform 1. The lead screw mating seat 5b has a threaded hole adapted to the lead screw 5a. One end of the first connecting rod 5d near the lead screw mating seat 5b is connected to a lead screw connecting seat 5c. The lead screw connecting seat 5c has a mounting hole adapted to the lead screw 5a. The lead screw 5a is threadedly inserted into the lead screw mating seat 5b and forms a lead screw nut kinematic pair with the lead screw mating seat 5b. Its inner end is rotatably installed in the mounting hole of the lead screw connecting seat 5c.

[0027] The linkage assembly includes two second linkages 5e disposed opposite to each other on both sides of the first linkage 5d. The inner ends of the second linkages 5e are hinged to the first linkage 5d, and the outer ends of the second linkages 5e are connected to corresponding sliding fit parts 5e1. The upper surface of each second linkage 5e has protruding support protrusions 5e2 that are adapted to the corresponding mounting bases 2. The sliding fit parts 5e1 and the support protrusions 5e2 are integrally formed on the corresponding second linkages 5e. In this embodiment, there are two sets of linkage assemblies, each disposed at one end of the first linkage 5d. Correspondingly, linear sliding assemblies corresponding to each second linkage 5e are disposed on both sides of the first linkage 5d. Four sliding grooves 1b are symmetrically distributed on both sides of the first linkage 5d. The sliding grooves 1b and the first linkage 5d extend horizontally, and their extension directions are perpendicular to each other.

[0028] like Figure 1 , Figures 3 to 5As shown, a mounting base 2 is provided on each side of the first connecting rod 5d. The mounting base 2 is slidably mounted on the tooling mounting platform 1 via two sliding mating parts 5e1 on the same side. Specifically, the bottom surface of the mounting base 2 is provided with mounting holes that are adapted to the sliding mating parts 5e1. The upper end of each sliding mating part 5e1 is rotatably mounted in the corresponding mounting hole of the mounting base 2. The bottom surface of each mounting base 2 is slidably supported on the top surface of the corresponding support protrusion 5e2. The two mounting bases 2 are parallel to each other and have the same extension direction as the first connecting rod 5d. Each mounting base 2 includes a base plate 2a and two rotating shaft mounting bases 2b respectively mounted at both ends of the base plate 2a. Each first driving device 4 includes a rotating shaft 4a and a rocker arm 4b fixedly connected to one end of the rotating shaft 4a. The two ends of each rotating shaft 4a are rotatably mounted on the corresponding rotating shaft mounting base 2b. The detection rollers 3 are synchronously rotated and fitted onto the corresponding rotating shafts 4a. The axis of the detection rollers 3 is parallel to the sliding direction of the first connecting rod 5d. When the rotating lead screw 5a drives the first connecting rod 5d to slide, the first connecting rod 5d can drive each mounting seat 2 to slide along the slide groove 1b through the second connecting rods 5e that are hinged to it, thereby causing the two detection rollers 3 to move closer or further apart. By rotating the rocker arm 4b, the corresponding rotating shaft 4a can be driven to rotate, thereby driving the corresponding detection roller 3 to rotate. The rotating shaft 4a can also be rotated by a motor control. In this embodiment, a manual method is used, which is low in cost, reliable in structure, and less prone to failure.

[0029] like Figure 3 As shown, this embodiment also includes several flatness inspection modules 12. Each flatness inspection module 12 is detachably mounted on the mounting base 2. Each flatness inspection module 12 has a mounting notch 12a at its bottom. The bottom of the mounting notch 12a is an arc-shaped structure adapted to the detection roller 3. The two side walls of the notch extend upward from the bottom surface of the flatness inspection module 12 to the bottom of the notch. The bottom surface of each flatness inspection module 12 is supported on the upper surface of the corresponding mounting base 2, and each detection roller 3 passes through the corresponding mounting notch 12a. The upper surfaces of each flatness inspection module 12 are all located on the same horizontal plane.

[0030] This embodiment can be used for straightness and torsion testing of various types of magnesium-aluminum alloy products. See [link to documentation]. Figure 3 When inspecting aluminum alloy sheet A, and a flat surface is needed as the inspection reference, the flatness inspection modules 12 are arranged in a horizontal array to form an inspection surface dot matrix. The size of the inspection area can be adjusted by adjusting the distance between the two inspection rollers 3. Assembly and disassembly are convenient and quick, and the structure is stable and reliable. (See also...) Figure 4 When inspecting aluminum alloy bars, the inspection roller 3 can be rotated using the rocker arm 4b, thereby rotating the aluminum alloy bar and allowing observation of its maximum straightness and torsion. When the aluminum alloy bar can be straightened, the position of maximum bending can be directly marked, facilitating shaping positioning and rapid retesting after shaping. See also Figure 5 When inspecting aluminum alloy profile C, the inspection roller 3 can simultaneously contact the circumferential outer wall of aluminum alloy profile C and the surface of cantilever C1, without the need for other special inspection tools, to inspect the straightness and torsion of aluminum alloy profile C. If the inspection roller 3 and flatness inspection module 12 are deformed or worn, they can be replaced to restore inspection accuracy.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
