However, when it is used, the size of the object to be detected needs to be smaller than the size of the assembled screw cylinder, which is inconvenient for tensile testing of some larger-sized objects, resulting in greater limitations in its use and a smaller scope of application.

Detailed implementation mode

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , wherein Figure 1 is a schematic structural diagram of a preferred embodiment of the stainless steel wire tensile strength detection device provided by the present utility model; Figure 2 is Figure 1 a schematic structural diagram of the clamping assembly shown; Figure 3 is Figure 2 a schematic enlarged structural diagram of part A shown; Figure 4 is Figure 1 a schematic enlarged structural diagram of part B shown. A stainless steel wire tensile strength detection device includes a workbench 1, a pulling cylinder 2 is arranged on the top of the workbench 1, a tensiometer 3 is arranged on the top of the workbench 1, and a first moving bar 4 is slidably connected inside the workbench 1; a clamping assembly 5, the clamping assembly 5 is arranged on one side of the first moving bar 4, the clamping assembly 5 includes a fixed tube 51, a sliding rod 52, a fixed disk 53, a first moving tube 54 and a second moving tube 55, a fixed tube 51 is fixedly connected to one side of the first moving bar 4, a sliding rod 52 is slidably connected inside the fixed tube 51, one end of the sliding rod 52 is fixedly connected to a fixed disk 53, and a first moving tube 54 and a second moving tube 55 are respectively slidably connected inside the fixed disk 53.

[0023] In the specific implementation process, as Figure 2 and Figure 3 shown, a positioning bolt 7 is arranged inside the fixed tube 51, and a positioning hole 6 matched with the positioning bolt 7 is opened inside the fixed tube 51.

[0024] A positioning groove 8 is opened inside the fixed tube 51, a positioning bar 9 is slidably connected to the outer side of the sliding rod 52, and the outer side of the positioning bar 9 is slidably connected to the inner wall of the positioning groove 8.

[0025] A lead screw mechanism 10 is arranged inside the fixed disk 53, and a rotating tube 11 is rotatably connected to the outer side of the second moving tube 55.

[0026] The inner part of the rotating pipe 11 is threadedly connected with a pressing rod 12, and a clamping groove 13 for cooperating with the pressing rod 12 is arranged inside the first moving pipe 54.

[0027] It should be noted that: First, one end of the welding wire needs to be positioned and wound through the rotating rod 17. Then, according to the size of the welding wire, the staff makes the lead screw mechanism 10 start to operate. When the lead screw mechanism 10 operates, it can drive the first moving pipe 54 and the second moving pipe 55 to move in opposite directions, so that the first moving pipe 54 and the second moving pipe 55 can clamp the stainless steel welding wire. When the inner circles of the first moving pipe 54 and the second moving pipe 55 are both in contact with the outer side of the stainless steel welding wire, rotate the rotating pipe 11. When the rotating pipe 11 rotates, it can drive the pressing rod 12 to move, so that the pressing rod 12 can enter the interiors of the first moving pipe 54 and the second moving pipe 55, thereby pressing and fixing the stainless steel welding wire, preventing the welding wire from sliding during the tensile test, and at the same time, it can press and clamp stainless steel welding wires of different sizes. When it is necessary to disassemble the sliding rod 52, rotate the positioning bolt 7 so that the positioning bolt 7 disengages from the inside of the positioning strip 9 and the fixed pipe 51, and then pull the sliding rod 52, so that the sliding rod 52 disengages from the inside of the fixed pipe 51, thereby enabling the sliding rod 52 to be disassembled.

[0028] Reference Figure 1 and Figure 4 As shown in the figure, a second moving strip 14 is slidably connected inside the workbench 1, and a motor 15 is fixedly connected to one side of the second moving strip 14.

[0029] The output end of the motor 15 is fixedly connected with a connection disk 16, and a rotating rod 17 is fixedly connected to one side of the connection disk 16.

[0030] A first through hole 18 is arranged inside the rotating rod 17, and a second through hole 19 is arranged inside the rotating rod 17.

[0031] It should be noted that: When performing a tensile strength test on the stainless steel welding wire, first, the staff passes one end of the welding wire through the interiors of the second through hole 19 and the first through hole 18, and then presses one end of the welding wire against the outer side of the rotating rod 17. Start the motor 15. Under the action of the motor 15, it can drive the rotating rod 17 to rotate, thereby winding and fixing one end of the welding wire.

[0032] The working principle of a stainless steel welding wire tensile strength detection device provided by the present utility model is as follows:

[0033] When the staff needs to conduct a tensile strength test on the stainless steel welding wire by using this device, first, the staff makes one end of the welding wire pass through the second through-hole 19 from bottom to top, and then makes one end of the welding wire pass through the inside of the first through-hole 18 from top to bottom. Then, press one end of the welding wire against the outside of the rotating rod 17, start the motor 15, and the motor 15 can drive the rotating rod 17 to rotate. When the rotating rod 17 moves, it can drive the welding wire to wind, so as to position and fix one end of the welding wire. Then, the staff places the other end of the welding wire at the middle position between the first moving tube 54 and the second moving tube 55. According to the size of the stainless steel welding wire, the lead screw mechanism 10 starts to operate. Under the action of the lead screw mechanism 10, the first moving tube 54 and the second moving tube 55 can move in opposite directions, so that the inner circles of the first moving tube 54 and the second moving tube 55 can be closely attached to the outside of the stainless steel welding wire. Then, rotate the rotating tube 11 to make the pressing rod 12 start to move, so that the pressing rod 12 can press and fix the stainless steel welding wire. Then, use the pulling cylinder 2 and the tensile tester 3 to conduct a tensile strength test on the fixed stainless steel welding wire, which is convenient for the staff to conduct a tensile strength test on stainless steel welding wires of different sizes and improves the tensile strength test efficiency of the stainless steel welding wire to a certain extent.
