Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical steel rolling machinery, in particular to a FDS connected TSS sample positioning and clamping device. Background Art

[0002] The FDS (Flow Drill Screw) process is the flow drill screw connection process, referred to as FDS. It is a process that drives the flow drill screw at a high speed generated by the connection tool, causing it to generate heat through friction with the plate, and drilling, tapping, and tightening are completed in one step under the action of feed pressure, and finally a fully engaged threaded connection is formed between the plate and the screw. It has high strength and small thermal deformation. Parts produced by the FDS connection process must be evaluated and certified when used by the main engine manufacturer. Manufacturers often need to test the mechanical data related to the connection joint to ensure the comprehensive performance of the equipment. The most common of these is the tensile shear test (TSS). The tensile shear test is a tensile test that measures the mechanical properties and fracture form of the connection joint by applying a tensile force to the mating surfaces of the parallel connection specimens and stretching them at a certain rate.

[0003] However, existing FDS connection equipment often relies on manual operation to prepare specimens for tensile shear tests. This lack of precision and efficiency carries high safety risks, including the risk of injury from die crushing. Therefore, there is an urgent need to develop an FDS-connected TSS specimen positioning and clamping device to ensure specimen processing accuracy, improve test efficiency, and protect operator safety.

[0034] In a possible implementation manner, T-shaped bolts 5 are provided around the top of the base 11 . The T-shaped bolts 5 pass through the clamp body 1 and are fixed to the clamp body 1 by nuts 6 .

[0035] In a possible embodiment, a pressing head 10 is provided above the center of the clamp body 1 , the upper end of the pressing head 10 is connected to the transmission system 9 , and a rivet 7 is provided at the lower end of the pressing head 10 .

[0036] In one possible embodiment, the fixture body 1 is machined with a rectangular groove along the center of symmetry, and the length is consistent with the sample requirements. The upper side of the groove is the sample positioning side. When the sample is placed, the long side of the sample is close together, and the other side can be adjusted according to the width of the sample. The width direction of the groove is consistent with the width of the sample, with a minimum width of 40 mm. When it is greater than 40 mm, it is adjusted by an adjustable positioning plate 2. The adjustable positioning plate 2 is cylindrical and adopts an eccentric structure. The positioning and clamping of samples of different widths are adjusted by the size of the eccentricity. In order to prevent the sample from loosening during processing, a movable pressure plate 3 is used for clamping. One end of the movable pressure plate 3 is connected to the fixture body with a bolt, and the other end is tightened to the sample 8 by an adjusting bolt.

[0037] In one possible embodiment, a countersunk hole is provided in the center of the fixture body 1, and a support sleeve 4 is embedded in the center hole. The function of the support sleeve 4 is to be able to drill holes through the rivet 7 and to ensure that the extrusion deformation of the sample during the riveting process is within the quality controllable range. The inner hole diameter is selected according to the size of the rivet 7, and the outer diameter of the support sleeve 4 is ΦD0H7 / h6 clearance matched with the center countersunk hole of the fixture body 1. The two specimens 8 to be riveted are stacked together through the groove. When the specimen 8 is placed, one side is close to the upper side, and the other side is positioned by two adjustable positioning plates 2. One end of the two movable pressure plates 3 is installed on the fixture body 1 through a screw hole and can rotate freely around the bolt. The other end has a bolt screwed into it, and the specimen 8 can be pressed accordingly by the bolt so that it will not loosen during the riveting process.

[0038] In one possible embodiment, the entire clamping device is assembled and mounted on the machine base 11 using four T-bolts 5. The position can be freely adjusted within the T-slots of the machine base 11. The clamping head 10 on the device is aligned with the center of the fixture body 1, and the nuts 6 on the T-bolts 5 are tightened to complete the installation of the TSS specimen 8 positioning clamping device.

[0039] In one possible implementation, two TSS specimen plates are stacked in a groove in the fixture body 1, and the adjustable positioning plate 2 is adjusted to maintain the specimen riveted position accuracy. The clamping head 10 is aligned with the center of the fixture body 1 to ensure symmetrical riveting of the specimen, thereby guaranteeing the accuracy of the tensile data. The integrated positioning and clamping device and FDS connection equipment offer a simple structure, easy operation, and high connection accuracy, effectively preventing injuries to personnel caused by the stamping die, thus achieving intrinsic safety of the equipment, which is of practical significance.

[0040] By adopting the above technical solutions:

[0041] The designed TSS specimen positioning and clamping device is used in conjunction with the FDS riveting equipment. The clamp body 1 is aligned to its center using the clamping head 10 on the alignment device. Simultaneously, two CTS specimen plates 8 are stacked on the clamp body 1, and the specimen riveting position accuracy is maintained by the adjustable positioning plate 2. The device has a simple structure, easy operation, and high connection precision, effectively preventing operator damage from the stamping die and improving experimental safety and reliability.

[0042] Working principle, see Figure 1-3 During use, after the clamping device is installed on the FDS equipment base 11 as described above, two TSS specimens 8 are stacked in the grooves of the fixture body. The adjustable positioning plate 2 is adjusted to maintain the specimen riveting position accuracy, and the specimens are then compressed using the movable pressure plate 3. The equipment is started, and the upper transmission system drives the compression head 10 downward to clamp the specimens. The internal spline rod drives the rivet head, causing the rivet 7 to rotate at high speed. Under a certain pressure, the rivet 7 penetrates the specimen plates in a hot melt state, riveting the two specimen plates together and forming the specific FDS rivet connection.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
