Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a hardware plate testing fixture. Background Technology

[0002] On equipment or housings made of metal, hardware plates with an inclined bearing surface are often used (such as the guide plate on a scale used to push or push items in or out). During installation, the bearing surface of the hardware plate forms an angle with the horizontal plane, and the fasteners on the hardware plate are fastened to the other housing of the equipment. Before installation, to check whether the compressive strength of the hardware plate meets the requirements and to ensure the service life of the product, testing fixtures are usually used to test the hardware plate.

[0003] However, with the existing testing fixtures, the hardware plate is placed horizontally and the hammer is pressed down vertically during testing. Since the direction of force on the hardware plate during testing is different from that during normal use, the measurement results cannot accurately reflect the compressive strength of the hardware plate during use, resulting in inaccurate test results. Utility Model Content

[0004] Therefore, it is necessary to provide a hardware plate testing fixture to address the shortcomings of existing technologies.

[0005] A hardware plate testing fixture is used to test a hardware plate. The hardware plate includes two opposing foot plates and a force-bearing plate connected to the two foot plates. The foot plates have hooks protruding horizontally outward. The force-bearing plate is inclined, and its outer surface is the force-bearing surface. The hardware plate testing fixture includes a base plate, a positioning frame and a support frame mounted on the upper surface of the base plate, a pressing cylinder mounted on the support frame, and a hammer assembly mounted on the pressing cylinder. The hardware plate for testing is mounted on the positioning frame, and the base plate supports the hardware plate from the bottom position. The pressing cylinder drives the hammer assembly to adjust its position vertically, so that the hammer assembly presses down on the hardware plate or moves upward away from the hardware plate. The hammer assembly includes a pressure plate, two linkage plates mounted on the pressure plate, two bearings respectively mounted on the two linkage plates, a first linkage rod mounted on the two bearings, and a second linkage rod mounted on the first linkage rod. The end of the second linkage rod away from the first linkage rod is fixed to the pressing cylinder. The linkage plates and the pressure plate mounted on the linkage plates can rotate around the axis of the first linkage rod.

[0006] In one embodiment, the first linkage rod and the second linkage rod are arranged in a T-shape, with the first linkage rod passing horizontally through one end of the second linkage rod and being fixedly installed thereon.

[0007] In one embodiment, the inner side of the linkage plate is provided with a mating hole, the bearing is installed on the mating hole, and the end of the first linkage rod is installed with the inner ring of the bearing.

[0008] In one embodiment, the positioning frame includes a back plate, a front mounting plate, fasteners, and several fixing components. The back plate is located behind the front mounting plate and is mounted on a base plate by the fasteners. The front mounting plate is mounted on the back plate by the fasteners. The fasteners include a first connecting part and a second connecting part. The first connecting part is U-shaped and the second connecting part is connected to one side of the first connecting part. The top of the first connecting part is provided with a downwardly extending latch.

[0009] In one embodiment, the number of fasteners is two, and several sets of mounting holes are provided on both sides of the front mounting plate. During assembly, the two fasteners are respectively installed on the mounting holes on both sides of the mounting plate from the front through fixing members.

[0010] In one embodiment, the positioning frame further includes a limiting member mounted on the front side of the front mounting plate.

[0011] In one embodiment, the support frame includes two first support plates disposed opposite each other and a second support plate mounted on the two first support plates, the second support plate being parallel to the base plate, and the pressing cylinder being mounted on the second support plate.

[0012] The beneficial effects of this utility model hardware plate testing fixture are as follows: by setting a pressure plate, a linkage plate, a bearing, a first linkage rod, and a second linkage rod on the hammer assembly, the first linkage rod and the linkage plate are connected by a bearing, and the linkage plate and the pressure plate installed on the linkage plate can rotate around the axis of the first linkage rod. During the test, the pressure plate is in contact with the force plate, and the pressure plate is completely pressed down on the force plate, thereby effectively simulating the stress situation of the hardware plate during use, improving the accuracy of the testing fixture during testing, and making it highly practical.

[0023] Please see Figures 1 to 4 This utility model provides a hardware plate testing fixture for testing a hardware plate 100. The hardware plate 100 includes two feet 101 arranged opposite to each other and a force plate 102 connected to the two feet 101. The feet 101 are provided with hooks 103 protruding outward horizontally. The force plate 102 is arranged at an angle and the outer side of the force plate 102 is the force-bearing surface.

[0024] The hardware plate testing fixture includes a base plate 10, several support feet 20 installed at the bottom of the base plate 10, a positioning frame 50 and a support frame 30 installed on the upper surface of the base plate 10, a pressing cylinder 40 installed on the support frame 30, and a hammer assembly 60 installed on the pressing cylinder 40. The hardware plate 100 used for testing is installed on the positioning frame 50. The base plate 10 supports the hardware plate 100 from the bottom position. The pressing cylinder 40 drives the hammer assembly 60 to adjust its position vertically, so that the hammer assembly 60 presses down on the hardware plate 100 or moves upward away from the hardware plate 100.

[0025] The positioning frame 50 includes a back plate 51, a front mounting plate 52, fasteners 53, limiting members 54, and several fixing members. The back plate 51 is located behind the front mounting plate 52. The back plate 51 is installed on the base plate 10 by fixing members, and the front mounting plate 52 is installed on the back plate 51 by fixing members.

[0026] In this embodiment, there are two fasteners 53. Each fastener 53 includes a first connecting part 531 and a second connecting part 532. The first connecting part 531 is U-shaped, and the second connecting part 532 is connected to one side of the first connecting part 531. The top of the first connecting part 531 is provided with a downwardly extending slot 533. Several sets of mounting holes 521 are provided on both sides of the front mounting plate 52. During assembly, the two fasteners 53 are respectively installed on the mounting holes 521 on both sides of the mounting plate from the front through fixing members. Furthermore, according to the length of the hardware plate 100 to be tested, the fasteners 53 are selected to be installed on the mounting holes 521 at the required positions. During installation, the fixing member passes through the second connecting part 532 and is installed on the mounting holes 521 of the front mounting plate 52. The limiting member 54 is installed on the front side of the front mounting plate 52.

[0027] The support frame 30 includes two first support plates 31 arranged opposite to each other and a second support plate 32 mounted on the two first support plates 31. The second support plate 32 is parallel to the base plate 10, and the pressing cylinder 40 is mounted on the second support plate 32.

[0028] The hammer assembly 60 includes a pressure plate 61, two linkage plates 62 mounted on the pressure plate 61, two bearings 63 respectively mounted on the two linkage plates 62, a first linkage rod 64 mounted on the two bearings 63, and a second linkage rod 65 mounted on the first linkage rod 64. The first linkage rod 64 and the second linkage rod 65 are T-shaped. The first linkage rod 64 passes horizontally through one end of the second linkage rod 65 and is fixed to the second linkage rod 65 by screws or other means. The end of the second linkage rod 65 away from the first linkage rod 64 is fixed to the drive rod of the pressing cylinder 40.

[0029] The inner side of the linkage plate 62 is provided with a mating hole 621, and the bearing 63 is installed on the mating hole 621. The end of the first linkage rod 64 is installed with the inner ring of the bearing 63. Since the bearing 63 is used to connect the first linkage rod 64 and the linkage plate 62, the linkage plate 62 and the pressure plate 61 installed on the linkage plate 62 can rotate around the axis of the first linkage rod 64.

[0030] During testing, the hardware plate 100 to be tested is first installed on the positioning frame 50. The hooks 103 on both sides of the hardware plate 100 are engaged in the slots 533 of the fasteners 53. The first connecting parts 531 of the two fasteners 53 limit the hardware plate 100 from both sides. The limiting member 54 limits the hardware plate 100 from the rear. The bottom of the hardware plate 100 is in contact with the base plate 10. The force plate 102 on the hardware plate 100 is vertically opposite to the pressure plate 61. The pressing cylinder 40 drives the hammer assembly 60 to press down. After the pressure plate 61 contacts the force plate 102, the pressure plate 61 rotates and adjusts until the pressure plate 61 is in contact with the force plate 102 and the pressure plate 61 is fully pressed down on the force plate 102. The pressing cylinder 40 then drives the hammer assembly 60 to move upward. After multiple tests, if the hardware plate 100 does not deform or the degree of deformation is within the set value, then the hardware plate 100 is a qualified product.

[0031] The beneficial effects of this utility model hardware plate testing fixture are as follows: by setting a pressure plate 61, a linkage plate 62, a bearing 63, a first linkage rod 64, and a second linkage rod 65 on the hammer assembly 60, the first linkage rod 64 and the linkage plate 62 are connected by the bearing 63, the linkage plate 62 and the pressure plate 61 installed on the linkage plate 62 can rotate around the axis of the first linkage rod 64. During the test, the pressure plate 61 is in contact with the force plate 102, and the pressure plate 61 is completely pressed down on the force plate 102, thereby effectively simulating the force situation of the hardware plate 100 during use, improving the accuracy of the testing fixture during testing, and making it highly practical.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
