Description

Technical Field

[0001] The utility model relates to the technical field of testing tools, in particular to a tool used for testing deformation of a galvanized plate. Background Art

[0002] Galvanized sheet refers to a steel sheet with a layer of zinc on the surface. Galvanizing is a commonly used economical and effective rust prevention method. About half of the world's zinc production is used for this process. After production, the galvanized sheet needs to be pressurized for deformation testing to detect whether it is qualified.

[0003] When a deformation test is performed on a galvanized sheet without locking the clamping position, the galvanized sheet under test may be displaced. This is because deformation tests need to be performed on different positions of the galvanized sheet during the test, and the clamping position of the tooling in the prior art is set as a roller, which will move with the roller when the sheet is compressed and deformed, resulting in inaccurate sheet deformation test data. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a tooling for testing the deformation of galvanized sheet metal, which has the advantages of anti-displacement during testing and solves the problem that the galvanized sheet metal under test may be displaced when the deformation test is carried out on the galvanized sheet metal without limiting the locking of the clamping parts.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tool for testing the deformation of a galvanized sheet, comprising a clamping mechanism arranged on the upper surface of a tool base;

[0006] The clamping mechanism comprises a support frame, which is arranged above the tooling base, a connecting frame is arranged inside the support frame, a rotating shaft is arranged horizontally inside the connecting frame and inside the support frame, and a pressing roller is fixed on the outside of the two rotating shafts for clamping the galvanized sheet body, and a locking assembly is arranged on the left side of the front of the support frame for locking the rotating shaft to prevent further rotation;

[0007] The locking assembly includes a guide rail arranged on the left side of the front face of the support frame, a synchronization block is slidably arranged on the outer side of the guide rail, an intermediate plate is fixed on the right side of the synchronization block and directly below the support frame, friction plates are arranged on the outer sides of the two intermediate plates for fitting with the rotating shaft to increase the locking friction force, a fixing plate is arranged on the front side of the support frame and on the right side of the bottom rotating shaft, a locking frame connected to the connecting frame is arranged on the front side of the support frame, locking screw holes are arranged on the outer sides of the locking frame and the fixing plate, and locking bolts are threadedly connected to the inner sides of the two locking screw holes for abutting against the rotating shaft after tightening to prevent its rotation and cause displacement of the plate body.

[0008] Furthermore, an adjustment opening is provided on the front side of the support frame, and the upper rotating shaft is slidably arranged inside the adjustment opening.

[0009] Furthermore, a synchronization rod connected to the front side of the connecting frame is fixed on the upper surface of the synchronization block, so as to enable the synchronization block to move synchronously with the connecting frame.

[0010] Furthermore, the cross-section of the friction plate is arc-shaped to increase the contact surface with the rotating shaft.

[0011] Furthermore, a plate support block is provided inside the support frame and outside the bottom pressure roller for placing the galvanized plate for deformation testing.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The tooling for testing the deformation of galvanized sheet is provided with a clamping mechanism. The pressure roller and locking assembly in the clamping mechanism can stably clamp the galvanized sheet to prevent displacement during the deformation test. Compared with the roller clamping position used in the prior art, the accuracy of the test is significantly improved. The locking bolt, friction plate and other structures in the locking assembly can effectively lock the rotating shaft to prevent displacement of the sheet during the test. Since the locking assembly can ensure the stability of the sheet during the test, more reliable deformation test data can be obtained, which is very important for evaluating the quality of the galvanized sheet. The tooling can adapt to galvanized sheets of different sizes, increasing the versatility and flexibility of the tooling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Please refer to Figure 1-3 In this embodiment, a tool for testing deformation of a galvanized sheet metal includes a clamping mechanism 2 arranged on the upper surface of a tool base 1.

[0020] Example 2: Please refer to Figure 2-3 On the basis of the first embodiment, in order to improve the anti-displacement accuracy of the deformation test, the clamping mechanism 2 in this embodiment includes a support frame 21, and the support frame 21 is arranged above the tooling base 1. A connecting frame 22 is provided inside the support frame 21. A rotating shaft 23 is horizontally provided inside the connecting frame 22 and the support frame 21. Pressure rollers 24 are fixed on the outside of the two rotating shafts 23 for clamping the galvanized sheet body. A locking assembly 25 is provided on the left side of the front of the support frame 21 for locking the rotating shaft 23 to prevent further rotation.

[0021] The locking assembly 25 includes a guide rail 251 arranged on the left side of the front face of the support frame 21, a synchronous block 252 is slidably arranged on the outer side of the guide rail 251, and an intermediate plate 253 is fixed to the right side of the synchronous block 252 and directly below the support frame 21. When the locking assembly 25 needs to work, the synchronous block 252 slides on the guide rail 251 and keeps synchronous movement with the connecting frame 22 through the synchronous rod 26. The outer sides of the two intermediate plates 253 are provided with friction plates 254 to fit the rotating shaft 23 to increase the locking friction force. A fixed plate 255 is provided on the front side of the support frame 21 and on the right side of the bottom rotating shaft 23. The support frame 2 1 is provided with a locking frame 256 connected to the connecting frame 22 on the front side, and locking screw holes 257 are provided on the outer sides of the locking frame 256 and the fixing plate 255, and locking bolts 258 are threadedly connected to the insides of the two locking screw holes 257, so as to abut against the rotating shaft 23 after tightening to prevent the rotating shaft 23 from rotating and causing the plate body to shift. The locking bolts 258 are tightened and passed through the locking screw holes 257. When tightened, the head of the locking bolt 258 abuts against the rotating shaft 23 and is locked in the current position, so that the pressure roller 24 cannot rotate, thereby ensuring the stability of the galvanized plate body during the deformation test.

[0022] In this embodiment, an adjustment port is provided on the front of the support frame 21, and the upper rotating shaft 23 is slidably arranged inside the adjustment port. A synchronization rod 26 connected to the front of the connecting frame 22 is fixed on the upper surface of the synchronization block 252, so as to make the synchronization block 252 move synchronously with the connecting frame 22. The cross-sectional shape of the friction plate 254 is an arc-shaped, so as to increase the contact surface with the rotating shaft 23. The movement of the synchronization block 252 causes the middle plate 253 to move accordingly, and the friction plate 254 will fit onto the rotating shaft 23. The arc-shaped cross-sectional design of the friction plate 254 increases the contact area with the rotating shaft 23, thereby increasing the friction force during locking to prevent the rotating shaft 23 from rotating. A plate support block 27 is provided inside the support frame 21 and on the outside of the bottom pressure roller 24 for placing the galvanized sheet for deformation testing. The locking bolt 258 is turned in the reverse direction to reduce its contact and friction with the rotating shaft 23. The friction plate 254 will no longer be excessively in contact with the rotating shaft 23, allowing the rotating shaft 23 to rotate freely to adjust the test position of the galvanized sheet.

[0023] It should be noted that a cylinder is provided on the upper surface of the support frame 21, and the output shaft of the cylinder is connected to the connecting frame 22. After the galvanized sheet body is placed, power is provided by an external cylinder, and the relative position between the connecting frame 22 and the bottom rotating shaft 23 is controlled by the extension and contraction of the cylinder, thereby controlling the clamping force of the pressure roller 24.

[0024] The working principle of the above embodiment is:

[0025] After the galvanized sheet is placed, power is provided by an external cylinder, and the relative position between the connecting frame 22 and the bottom rotating shaft 23 is controlled by the extension and contraction of the cylinder, thereby controlling the clamping force of the pressure roller 24 to place the galvanized sheet under the deformation testing device. When the locking assembly 25 needs to work, the synchronization block 252 slides on the guide rail 251 and keeps synchronous movement with the connecting frame 22 through the synchronization rod 26. The movement of the synchronization block 252 causes the middle plate 253 to move accordingly, and the friction plate 254 will fit onto the rotating shaft 23. The arc-shaped cross-section design of the friction plate 254 increases the friction with the rotating shaft 23. The contact area increases the friction during locking and prevents the shaft 23 from rotating. The locking bolt 258 is tightened and passed through the locking screw hole 257. When tightened, the head of the locking bolt 258 will press against the shaft 23 and lock it in the current position, so that the pressure roller 24 cannot rotate, thereby ensuring the stability of the galvanized sheet during the deformation test. The locking bolt 258 is turned in the opposite direction to reduce its contact and friction with the shaft 23. The friction plate 254 will no longer be in excessive contact with the shaft 23, allowing the shaft 23 to rotate freely to adjust the test position of the galvanized sheet.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0027] If this patent discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection can also be replaced by an integrated structure (for example, manufactured by a casting process) (except where it is obviously impossible to use an integrated forming process).

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
