[0016] Preferably, both ends of the cross bar are slidably connected to the two groups of trapezoidal groove blocks respectively, and a limiting long rod is fixedly installed in the inner cavity of the support base.

[0017] Preferably, the two groups of trapezoidal groove blocks are respectively slidably connected to both ends of the limiting long rod.

[0018] Preferably, the pushing plate is slidably connected to the inner cavity of the empty groove, and the height of the bottom position of the empty groove is higher than the top surface height of the feeding port.

[0019] Preferably, a usage method of an automatic loading and unloading device for a tensile testing machine includes the following steps:

[0020] Step 1: There is a horizontal height difference between the conveyor belt and the butt-jointed tensile testing equipment, and the height of the conveying and lifting seat component, that is, the conveyor belt, needs to be adjusted. The user can turn on the working mode of the second motor, and the lifting support plate drives the support block and the conveying and lifting seat component to move up or down until the conveyor belt on the conveying and lifting seat component is adjusted to the actual use height. Then, turn off the second motor. After that, the operator docks the adjusted conveying and lifting seat component with another tensile testing machine. After the horizontal heights are the same, the subsequent conveying and loading work can be started.

[0021] Step 2: The user can neatly stack multiple groups of hardware parts to be tested in the storage cavity. The empty groove is for the bottommost hardware part, and the subsequent hardware parts to be tested are stacked upwards. At this time, the user can turn on the hydraulic cylinder, and the pushing plate is pushed into the empty groove until the bottommost hardware part in the empty groove is pushed towards the feeding port. Then, this hardware part will enter the support base through the feeding port and will subsequently fall on the conveyor belt. At this time, the next bottommost hardware part will appear in the empty groove until all the hardware parts to be tested in the storage cavity are pushed into the feeding port.

[0022] Step 3: Before the hardware part to be tested enters the support base from the feeding port, turn on the working modes of the electric telescopic rod, the air pump, and the dust suction head component. During the falling process of the hardware part, the dust suction head component will suck the dust and impurities on its surface into the hose and finally discharge them from the dust discharge cover. The dust and impurities discharged from the dust discharge cover will fall into the dust collection box. After the work is completed, slide the dust collection box out of the support base to clean the dust and impurities inside the dust collection box;

[0023] Step 4: After the hardware part enters the dust removal chamber for dust removal, it directly falls on the conveyor belt of the conveying and lifting seat component. The conveyor belt will drive the hardware part to move towards the deviation correction component. Turn on the first motor, and then the two deviation correction plates will perform an alternating movement of approaching and moving away from each other. In this way, when the hardware part is conveyed to the deviation correction plates by the conveyor belt, the two deviation correction plates can correct the position of the hardware part to prevent the hardware part from deviating from the position of the conveyor belt. The hardware part will continue to be conveyed by the conveyor belt until it is sent to the working table of the testing machine, thus completing the workpiece feeding work.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. When it is necessary to send the hardware part to the tensile testing machine for testing, a conveyor or a conveyor belt is usually used for conveying the hardware part during feeding. During the conveying process, it is necessary to dock the feeding conveyor belt with the working platform of the tensile testing machine so that the hardware part can be conveyed to the working table of the testing machine. Since there is a horizontal height difference between the conveyor belt and the docked tensile testing equipment, it is necessary to adjust the height of the conveying and lifting seat component, that is, the conveyor belt. The user can turn on the working mode of the second motor. The second motor drives the second bevel gear to rotate forward or backward. At the same time, the second bevel gear will drive the first bevel gear to rotate. At this time, the first lead screw rotates forward or backward inside the bottom cavity seat. The lifting block is slidably limited in the bottom cavity seat, and the lifting block drives the lifting support plate to move up or down inside the inner cavity of the bottom cavity seat. The lifting support plate drives the support block and the conveying and lifting seat component to move up or down until the conveyor belt on the conveying and lifting seat component is adjusted to the actual use height, then turn off the second motor. Then the operator docks the conveying and lifting seat component with the other tensile testing machine. After the horizontal heights are the same, the subsequent conveying and feeding work can be started. This setting realizes the adjustment function of the height of the conveying and lifting seat component according to actual needs, is simple and fast to operate, improves work efficiency, and expands the applicable range of the equipment;

[0026] 2. The user can neatly stack multiple groups of hardware parts to be tested in the storage cavity. The hardware part at the bottom layer is in the empty slot, and the subsequent hardware parts to be tested are stacked upwards. At this time, the user can activate the hydraulic cylinder, which drives the pusher plate to extend. The pusher plate is pushed into the empty slot until the bottom-layer hardware part in the empty slot is pushed towards the feeding port. Then, this hardware part will enter the support base through the feeding port and subsequently fall onto the conveyor belt. When the bottom-layer hardware part leaves, due to gravity, the hardware parts originally in the upper layer will descend. At this time, the next bottom-layer hardware part will appear in the empty slot, and then rely on the pusher plate to push it into the feeding port, and so on, until all the hardware parts to be tested in the storage cavity are pushed into the feeding port;

[0027] 3. Before the hardware part to be tested enters the support base from the feeding port, activate the working modes of the electric telescopic rod, air pump, and dust suction head component. When the hardware part lands in the dust removal chamber, the dust suction head component starts the dust suction mode. At the same time, the electric telescopic rod drives the dust suction head component to move up and down reciprocally, which will improve the dust suction efficiency of the dust suction head component for the hardware part. During the falling process of the hardware part, the dust suction head component will suck the dust and impurities on its surface into the hose and finally discharge them from the dust discharge cover. The dust and impurities discharged from the dust discharge cover will fall into the dust collection box. After the work is completed, slide the dust collection box out of the support base to clean the dust and impurities inside the dust collection box. This operation can remove dust and impurities from the surface of the hardware part to be tested, making the surface of the hardware part clean and facilitating subsequent detection work;

[0028] 4. After the hardware part enters the dust removal chamber for dust removal, due to gravity, it will directly fall onto the conveyor belt on the conveyor lifting seat component. Activate the first motor, and the first motor drives the cam to rotate. The cam can make the contact block move up and down reciprocally, and then the two deviation rectifying plates make an alternating movement of approaching and moving away from each other. In this way, when the hardware part is conveyed to the deviation rectifying plates through the conveyor belt, the two deviation rectifying plates can correct the position of the hardware part to prevent the hardware part from deviating from the conveyor belt position. After using the deviation rectifying component to correct the position of the hardware part, the hardware part will continue to be conveyed through the conveyor belt until it is sent to the test bench of the testing machine, thus completing the workpiece blanking work. This setting can correct the position of the hardware part on the conveyor belt through the deviation rectifying component, preventing the hardware part from deviating from the conveyor belt when it lands on the conveyor belt and avoiding affecting the normal conveying and feeding work of the device.

[0048] In summary, the working principle of the present invention: When it is necessary to send the hardware parts to the tensile testing machine for testing, a conveyor or a conveyor belt is usually used for conveying the hardware parts during feeding. During conveying, it is necessary to dock the feeding conveyor belt with the working platform of the tensile testing machine so that the hardware parts can be conveyed to the testing machine workbench. However, there is a horizontal height difference between the conveyor belt and the docked tensile testing equipment, and it is necessary to adjust the height of the conveying and lifting seat component 11, that is, the conveyor belt. The user can turn on the working mode of the second motor 13. The second motor 13 drives the second bevel gear 19 to rotate forward or backward. At the same time, the second bevel gear 19 drives the first bevel gear 18 to rotate. At this time, the first lead screw 16 rotates forward or backward inside the bottom cavity seat 1. The lifting block 15 is limited and slides in the bottom cavity seat 1. The lifting block 15 drives the lifting support plate 14 to move up or down inside the cavity of the bottom cavity seat 1. The lifting support plate 14 drives the support block 12 and the conveying and lifting seat component 11 to move up or down until the conveyor belt on the conveying and lifting seat component 11 is adjusted to the actual use height, then the second motor 13 is turned off. Then the operator docks the conveying and lifting seat component 11 with the adjusted height with another tensile testing machine. After the horizontal heights are the same, the subsequent conveying and feeding work can be started. This setting realizes the adjustment function of the height of the conveying and lifting seat component 11 according to actual needs, is simple and fast to operate, improves work efficiency, and expands the application range of the equipment;

[0049] The user can stack multiple groups of hardware parts to be tested neatly in the storage cavity 33. The empty slot 34 is for the bottommost hardware part, and the subsequent hardware parts to be tested are stacked upwards. At this time, the user can activate the hydraulic cylinder 31. The hydraulic cylinder 31 drives the pusher plate 32 to extend. The pusher plate 32 is pushed into the interior of the empty slot 34 until the bottommost hardware part in the empty slot 34 is pushed towards the feed port 22. Then, this hardware part will enter the support base 21 through the feed port 22 and will subsequently fall onto the conveyor belt. When the bottommost hardware part leaves, due to the factor of gravity, the hardware parts originally in the upper layer will descend. At this time, the next bottommost hardware part will appear in the empty slot 34. Subsequently, rely on the pusher plate 32 to push it into the feed port 22, and so on, until all the hardware parts to be tested in the storage cavity 33 are pushed into the feed port 22;

[0050] Before the hardware part to be tested enters the support base 21 from the feed port 22, activate the working modes of the electric telescopic rod 231, the air pump 234, and the dust suction head component 236. When the hardware part lands in the dust removal chamber 24, the dust suction head component 236 starts the dust suction mode. At the same time, the electric telescopic rod 231 drives the dust suction head component 236 to move up and down reciprocally. The dust suction head component 236 will improve the dust suction efficiency of the hardware part. During the falling process of the hardware part, the dust suction head component 236 will suck the dust and impurities on its surface into the hose 233 and finally discharge them from the dust discharge cover 235. The dust and impurities discharged from the dust discharge cover 235 will fall into the dust collection box 23. After the work is completed, slide the dust collection box 23 out of the support base 21 and clean the dust and impurities inside the dust collection box 23. This operation can remove dust and impurities from the surface of the hardware part to be tested, making the surface of the hardware part clean and facilitating subsequent detection work on it;

[0051] After the hardware parts enter the dust removal chamber 24 for dust removal, due to gravity, they will directly fall onto the conveyor belt of the conveyor lifting seat component 11. The conveyor belt will drive the hardware parts to move towards the deviation rectifying component 25. The deviation rectifying component 25 is used to rectify the deviation of the hardware parts. When the first motor 251 is turned on, the first motor 251 drives the cam 254 to rotate. The cam 254 can make the contact block 255 move up and down reciprocally. Then, the reciprocating plate 256 and the connecting rod 257 move up and down reciprocally. Further, the cross bar 2591 moves up and down reciprocally. Due to the horizontal limitation of the limiting long rod 2592 on the trapezoidal groove block 259, the up and down movement of the cross bar 2591 will cause the trapezoidal groove block 259 to move reciprocally left and right. Then, the two deviation rectifying plates 258 make an alternating movement of approaching and separating from each other. In this way, when the hardware parts are conveyed to the deviation rectifying plates 258 by the conveyor belt, the two deviation rectifying plates 258 can rectify the position of the hardware parts, preventing the hardware parts from deviating from the conveyor belt position. After the position of the hardware parts is rectified by the deviation rectifying component 25, the hardware parts will continue to be conveyed by the conveyor belt until they are sent to the test machine workbench, thus completing the workpiece blanking work. This setting can rectify the position of the hardware parts on the conveyor belt through the deviation rectifying component 25, preventing the hardware parts from landing on the conveyor belt and deviating from the conveyor belt, and avoiding affecting the normal conveying and feeding work of the device.

10. A method for using an automatic loading and unloading device for a tensile testing machine, characterized in that: The automatic loading and unloading device for a tensile testing machine according to any one of claims 1 to 9 comprises the following steps: Step 1: There is a height difference between the conveyor belt and the connected tensile testing equipment, and the height of the conveyor lifting seat component (11), that is, the conveyor belt, needs to be adjusted; the user can start the working mode of the second motor (13), and the lifting support plate (14) drives the support block (12) and the conveyor lifting seat component (11) to move up or down until the conveyor belt on the conveyor lifting seat component (11) is adjusted to the actual use height, and then turn off the second motor (13). The operator then connects the conveyor lifting seat component (11) with the adjusted height to another tensile testing machine. After the horizontal heights are the same, the subsequent conveying and loading work can be started; Step 2: The user can neatly stack multiple groups of hardware to be tested in the storage cavity (33), with the bottom layer of hardware at the empty slot (34), and the hardware to be tested at the back stacked upwards. At this time, the user can open the hydraulic cylinder (31), and push the push plate (32) into the empty slot (34) until the bottom layer of hardware in the empty slot (34) is pushed into the feed port (22). Then, the hardware will enter the support seat (21) through the feed port (22), and will subsequently fall onto the conveyor belt. At this time, the next bottom layer of hardware will appear in the empty slot (34), until all the hardware to be tested in the storage cavity (33) are pushed into the feed port (22); Step 3: Before the hardware to be tested enters the support seat (21) from the feed port (22), the working mode of the electric telescopic rod (231), the air pump (234) and the dust collecting head component (236) are turned on. During the falling process of the hardware, the dust collecting head component (236) will suck the dust and impurities on its surface into the hose (233) and finally discharge them from the dust discharge cover (235). The dust and impurities discharged from the dust discharge cover (235) will fall into the dust collecting box (23). After the work is completed, the dust collecting box (23) is slid and pulled out from the support seat (21) to clean the dust and impurities inside the dust collecting box (23); Step 4: After the hardware enters the dust removal chamber (24) and is dusted, it falls directly onto the conveyor belt on the conveying lifting seat component (11). The conveyor belt will drive the hardware to move toward the correction component (25), turn on the first motor (251), and then the two sets of correction plates (258) will move alternately towards and away from each other. In this way, when the hardware is conveyed to the correction plates (258) through the conveyor belt, the two sets of correction plates (258) can correct the position of the hardware to prevent the hardware from deviating from the conveyor belt position. The hardware will continue to be conveyed through the conveyor belt until the hardware is delivered to the working table of the testing machine, thereby completing the workpiece unloading work.
