[0009] Preferably, the regulating component includes a connecting plate symmetrically arranged on the rear side of the supporting frame, and supporting brackets are installed in front of the left and right sides of the connecting plate, the front side of the supporting bracket passes through the groove opened on the rear side of the supporting frame and is connected to the movable sleeve, the interior of the movable sleeve is hollow, and a nozzle is installed on the inner wall of the movable sleeve, the rear side of the support frame is symmetrically installed with vertical rods, the outer side of the vertical rods is penetrated by the supporting bracket, and the outer side of the vertical rods is nested with a reset spring connected to the supporting bracket, a connecting rope is installed on one side of the connecting plate, and the other ends of the two connecting ropes are both wound and connected with the driven rod.

[0014] Another technical solution provided by the present invention is to provide a new method for detecting the tensile properties of titanium alloy materials, comprising the following steps: S1: First, insert the two new titanium alloy materials into the upper and lower clamping and stretching components respectively through the clamping and fixing components; S2: Then pull the plug column to the left first, and then manually pull the middle rack assembly forward. At this time, the three rack assemblies move together and drive the three sets of horizontal bidirectional screws to rotate together; S3: When the middle set of transverse bidirectional screws rotates, the meshing connection between the sector gear and the driven gear drives the driven rod to rotate. When the driven rod rotates, it simultaneously winds and reels the two connecting ropes. The two connecting ropes pull the upper and lower connecting plates inward at the same time. The connecting plates drive the support frame and the movable sleeve to move, so that the movable sleeve moves outside the longitudinal bidirectional screws. S4: At the same time, the connecting plate drives the piston assembly into the storage tube, so that the liquid lubricant in the storage tube enters the movable sleeve through the connecting hose, and then the liquid lubricant is sprayed to the outer side of the longitudinal bidirectional screw through the nozzle inside the movable sleeve to perform lubrication operation; S5: At the same time, the three sets of horizontal bidirectional screws rotate, driving the three sets of clamping mechanisms to clamp the two ends of the two new titanium alloy materials at the same time. Then the servo motor in the workbench is started to drive the longitudinal bidirectional screw to rotate. The longitudinal bidirectional screw drives the outer moving block and the crossbeam to move, so that the crossbeam drives the clamping and stretching assembly to apply a stable pulling force to one end of the new titanium alloy material, and then the inspection operation can be carried out.
[0015] Compared with the prior art, the present invention has the following beneficial effects: the novel titanium alloy material tensile property testing device and testing method facilitates lubrication of the outer side of the longitudinal bidirectional screw, thereby preventing the longitudinal bidirectional screw from rusting and causing movement jamming, thereby not interfering with the crossbeam's ability to apply stable tension to the test object, thereby improving the accuracy of tensile property testing of new materials such as novel titanium alloys. The specific contents are as follows: By manually pulling the rack assembly in the middle protective frame, the rack assembly drives the transverse bidirectional screw to rotate through the active gear. When the transverse bidirectional screw rotates, it is meshed with the fan gear and the driven gear to drive the driven rod to rotate, so that the driven rod pulls and reels the two connecting ropes at the same time. The two connecting ropes pull the two connecting plates inward respectively, and then the two connecting plates drive the moving sleeve to move on the outside of the longitudinal bidirectional screw, so that the moving sleeve with a hollow interior can spray liquid lubricant to the outside of the longitudinal bidirectional screw, which is convenient for lubricating the outside of the longitudinal bidirectional screw and avoiding the longitudinal bidirectional screw from rusting and causing the movement to become stuck. Therefore, it will not affect the lifting speed of the moving block, and will not interfere with the crossbeam applying stable tension to the test object, thereby improving the accuracy of tensile performance testing of new materials such as new titanium alloys.
[0016] When the sector gear rotates to separate from the sector gear, the stored force of the vortex spring can automatically drive the driven rod to rotate in the opposite direction and reset. Therefore, the stored force of the reset spring automatically drives the moving sleeve to reset, and then will not affect the subsequent lifting operation of the moving block. By cooperating with the storage tube and the piston assembly, the connecting plate automatically drives the piston assembly to move into the storage tube, so that the liquid lubricant in the storage tube is automatically transported to the movable sleeve through the connecting hose, so that the liquid lubricant can be sprayed out through the nozzle on the inner wall of the movable sleeve later. No additional power source such as a pump is required, thus saving energy. When the horizontal bidirectional screw rotates, it drives the two groups of clamping mechanisms connected by the outer thread on the right end to move inward at the same time, so that the three groups of clamping mechanisms can clamp the two ends of the two new titanium alloy materials at the same time, without the need to manually adjust the clamping one by one. The operation is convenient, saving time and effort, and the clamping force of multiple groups of clamping mechanisms is the same, avoiding different clamping forces due to operational errors during manual clamping, and failing to apply stable tension to the new titanium alloy material. Therefore, it can further ensure that stable tension is applied to the new titanium alloy material, and further improve the accuracy of tensile performance testing of new materials such as new titanium alloys.

The interior of the frame 11 is connected, and the right end of the plug-in column 20 is inserted into the corresponding locking hole 181. The left end of the middle horizontal bidirectional screw rod 12 passes through the left side of the protective frame 11 and is connected to the sector gear 121. A driven rod 13 located on the rear side of the middle horizontal bidirectional screw rod 12 is installed above the support plate 111, and a vortex spring 132 is connected to the outside of the driven rod 13, and the rear side of the sector gear 121 is meshed with the driven gear 131 installed on the left side of the driven rod 13. The diameter of the driven gear 131 is smaller than the diameter of the sector gear 121.
[0021] The regulating component includes a connecting plate 9 symmetrically arranged on the rear side of the support frame 2, and a supporting bracket 22 is installed in front of the left and right sides of the connecting plate 9. The front side of the supporting bracket 22 passes through the groove opened on the rear side of the support frame 2 and is connected to the movable sleeve 15. The interior of the movable sleeve 15 is hollow, and the inner side wall of the movable sleeve 15 is installed with a spray head. The rear side of the support frame 2 is symmetrically installed with a vertical rod 10, and the outer side of the vertical rod 10 passes through the supporting bracket 22. The outer side of the vertical rod 10 is nested and connected with a return spring 101 connected to the supporting bracket 22. A connecting rope 91 is installed on one side of the connecting plate 9, and the other ends of the two connecting ropes 91 are both wound and connected with the driven rod 13. The storage tube 7 is symmetrically installed on the rear side of the support frame 2, and the interior of the storage tube 7 is fitly connected with the piston assembly 71, and the other end of the piston assembly 71 is connected to the connecting plate 9, and the interior of the storage tube 7 is communicated with the interior of the movable sleeve 15 through the connecting hose 23 installed through the support frame 2.
[0022] First, insert the lower end of a new titanium alloy material into the upper through hole 61, and then move the new titanium alloy material upward so that the upper end of the new titanium alloy material is inserted into the accommodating groove in the upper clamping and stretching component 5 and squeezed into contact with the pressure sensor 51. At this time, the lower end of a new titanium alloy material is inserted into the upper inner side of the clamping mechanism 17 in the clamping and fixing component 6, and then the upper end of another new titanium alloy material is inserted into the lower through hole 61. Then, as shown above, insert another new titanium alloy material between the clamping and stretching component 5 and the clamping and fixing component 6. Then, manually pull the plug-in column 20 on the left side of the middle protective frame 11 to the left. At this time, the connecting spring 21 on the outside of the plug-in column 20 accumulates force, and at the same time, the right end of the plug-in column 20 is separated from the corresponding locking hole 181. Then, manually pull the rack assembly 18 in the middle protective frame 11 forward. At this time, the rack assembly 18 drives the active gear The wheel 122 and the transverse two-way screw rod 12 rotate 360 degrees, and the transverse two-way screw rod 12 drives the sector gear 121 to rotate 360 degrees. When the sector gear 121 rotates, it drives the driven gear 131 and the driven rod 13 to rotate. When the driven rod 13 rotates, it simultaneously reels and winds the upper and lower connecting ropes 91, and at the same time, the vortex spring 132 stores force. Since the diameter of the sector gear 121 is larger than the diameter of the driven gear 131, the rotation speed of the driven rod 13 is greater than the rotation speed of the transverse two-way screw rod 12, so that the driven rod 13 quickly reels and winds the connecting rope 91, and then the connecting rope 91 pulls the upper and lower connecting plates 9 to move inward at the same time, and the connecting plate 9 drives the movable sleeve 15 to move through the supporting brackets 22 installed on the left and right sides. At this time, the supporting bracket 22 moves stably on the outside of the vertical rod 10, and the return spring 101 stores force, so that the upper and lower two sets of movable sleeves 15 move inward on the outside of the longitudinal two-way screw rod 14.
[0023] At the same time, the connecting plate 9 drives the corresponding piston assembly 71 to move into the storage tube 7, squeezing the liquid lubricant temporarily stored in the storage tube 7 into the connecting hose 23, and then the connecting hose 23 transports the liquid lubricant to the movable sleeve 15 with a hollow interior. Then the liquid lubricant in the movable sleeve 15 is sprayed out through the nozzle installed on the inner side below, and the liquid lubricant is sprayed onto the outer side of the longitudinal bidirectional screw rod 14, which is convenient for lubricating the longitudinal bidirectional screw rod 14 and avoiding the jamming of the movable block 8 with the outer thread connection when the longitudinal bidirectional screw rod 14 rotates in the later stage. At the same time, the two movable blocks 8 in the upper group are set as shown in the attached figure. Figure 10 As shown, at this time, part of the liquid lubricant sprayed by the upper movable sleeve 15 drips and is collected in the groove 81, and then part of the liquid lubricant in the groove 81 flows directly to the inner wall of the movable block 8 for lubrication, and the other part of the liquid lubricant in the groove 81 flows through the first flow hole 82 and the second flow hole 83 to the inner wall of the movable block 8 for lubrication, thereby improving the lubrication effect.
[0024] When the sector gear 121 rotates to the point where it is no longer engaged with the driven gear 131, the stored force of the vortex spring 132 automatically drives the driven rod 13 to rotate in the opposite direction and reset. At this time, the connecting rope 91 is in the pay-out state, and then the stored force of the reset spring 101 automatically drives the support bracket 22, the connecting plate 9 and the movable sleeve 15 to move in the opposite direction and reset. The connecting plate 9 drives the piston assembly 71 to move in the opposite direction and reset, thereby preventing the movable sleeve 15 from hindering the movement of the movable block 8 in the later stage.
[0025] Example 2: The new titanium alloy material tensile performance testing device and testing method in this embodiment, based on Example 1, can automatically clamp and fix the two ends of two new titanium alloy materials at the same time, and the operation is convenient. For the specific structure, please refer to the attached Figure 5-Figure 6 As shown, the clamping and stretching assembly 5 and the clamping and fixing assembly 6 are both connected with two clamping mechanisms 17 that move toward each other, and the height of the clamping mechanism 17 in the clamping and stretching assembly 5 is smaller than the height of the clamping mechanism 17 in the clamping and fixing assembly 6, and through holes 61 are opened inside the upper and lower side surfaces of the clamping and fixing assembly 6. The right end of the transverse bidirectional screw rod 12 is penetrated and connected in the clamping and stretching assembly 5 and the clamping and fixing assembly 6, and the outer side of the right end of the transverse bidirectional screw rod 12 is threadedly connected to two clamping mechanisms 17.
[0026] When the rack assembly 18 in the middle protective frame 11 is pulled forward, the middle rack assembly 18 drives the two sets of rack assemblies 18 installed on the upper and lower sides to move forward together through the manual telescopic rods 19 installed on the upper and lower sides. At this time, the three sets of rack assemblies 18 move forward at the same time. Therefore, as shown above, the three sets of rack assemblies 18 drive the three sets of driving gears 122 and the horizontal two-way screw rod 12 to rotate together. When the horizontal two-way screw rod 12 rotates, it drives the two clamping mechanisms 17 connected to the outer thread of the right end to move inward at the same time, thereby making the two clamping mechanisms 17 in the upper and lower clamping and stretching assemblies 5 and the clamping fixed The two clamping mechanisms 17 in the fixed component 6 clamp and fix the two ends of the two new titanium alloy materials at the same time, without the need to manually adjust the clamping one by one, which is convenient to operate, saves time and effort, and at the same time makes the clamping force the same, which can further ensure that stable tension is applied to the new titanium alloy material, and further improve the accuracy of tensile performance testing of new materials such as new titanium alloys. After the rack component 18 is pulled forward to a certain position, the plug-in column 20 is manually released, and the plug-in column 20 is automatically inserted into another locking hole 181 through the stored force of the connecting spring 21, thereby fixing the rack component 18 after moving forward.
[0027] Then start the servo motor in the workbench 1, and the servo motor drives one of the longitudinal bidirectional screws 14 to rotate, and then one of the longitudinal bidirectional screws 14 drives the other longitudinal bidirectional screw 14 to rotate through the sprocket assembly connected below, so that the two longitudinal bidirectional screws 14 rotate at the same time. When the two longitudinal bidirectional screws 14 rotate, they drive the two moving blocks 8 connected on the upper and lower sides to move outward, so that the upper moving block 8 drives the upper crossbeam 3 and the clamping and stretching assembly 5 to pull the upper end of the upper new titanium alloy material upward until it breaks or reaches the preset condition, and the lower moving block 8 drives the lower crossbeam 3 and the clamping and stretching assembly 5 to pull the lower end of the lower new titanium alloy material downward until it breaks or reaches the preset condition. At this time, the force sensor 4 detects the force applied to the new titanium alloy material, and the rangefinder 16 detects the elongation of the new titanium alloy material. Later, through software processing in the computer, the tensile properties of the new titanium alloy material are finally obtained. (The selection of the force sensor 4 and the specific connection with the clamping and stretching assembly 5 are both existing technologies, so they are not described in detail here).
[0028] Example 3: The new titanium alloy material tensile performance detection device and detection method in this embodiment, based on the second embodiment, can automatically detect the stability of the clamping of the two clamping and stretching components 5. If the clamping and stretching components 5 are separated from the new titanium alloy material, an alarm can be issued in time. The specific structure is shown in the attached figure. Figure 1 and Figure 12As shown, a pressure sensor 51 is installed in the internal groove of the clamping and stretching assembly 5, a groove 81 is provided inside the upper surface of the upper movable block 8, and a first flow hole 82 and a second flow hole 83 are provided inside the movable block 8, the first flow hole 82 is connected to the bottom of the groove 81, and the second flow hole 83 is connected to the inner side of the first flow hole 82.
[0029] During the detection process, if the clamping and stretching assembly 5 is suddenly separated from the new titanium alloy material when pulling, one end of the new titanium alloy material is separated from the pressure sensor 51. The pressure sensor 51 detects that the pressure is reduced until there is no pressure. At this time, the pressure sensor 51 transmits this signal to the central processing module. The central processing module controls the alarm above the support frame 2 to sound an alarm. At the same time, the central processing module controls the servo motor to stop working to avoid danger.
[0030] In order to better demonstrate the specific detection method of the new titanium alloy material tensile performance detection device, this embodiment provides a detection method of a new titanium alloy material tensile performance detection device, including the following steps: Step 1: First, insert the two new titanium alloy materials into the upper and lower clamping and stretching components 5 respectively through the clamping and fixing components 6; Step 2: Then pull the plug column 20 to the left, and then manually pull the middle rack assembly 18 forward. At this time, the three sets of rack assemblies 18 move together and drive the three sets of horizontal bidirectional screw rods 12 to rotate together; Step 3: When the middle set of transverse bidirectional screw rods 12 rotates, the meshing connection between the sector gear 121 and the driven gear 131 drives the driven rod 13 to rotate. When the driven rod 13 rotates, the two connecting ropes 91 are wound and reeled. The two connecting ropes 91 pull the upper and lower connecting plates 9 to move inward at the same time. The connecting plates 9 drive the support bracket 22 and the movable sleeve 15 to move, so that the movable sleeve 15 moves outside the longitudinal bidirectional screw rod 14. Step 4: At the same time, the connecting plate 9 drives the piston assembly 71 into the storage tube 7, so that the liquid lubricant in the storage tube 7 enters the movable sleeve 15 through the connecting hose 23, and then the liquid lubricant is sprayed to the outer side surface of the longitudinal bidirectional screw 14 through the nozzle inside the movable sleeve 15 to perform lubrication operation; Step 5: At the same time, the three groups of horizontal bidirectional screw rods 12 rotate to drive the three groups of clamping mechanisms 17 to clamp the two ends of the two new titanium alloy materials at the same time, and then start the servo motor in the workbench 1 to drive the longitudinal bidirectional screw rod 14 to rotate.
