[0002] Stainless steel round bar is a cylindrical stainless steel product, widely used in automotive parts, aviation, aerospace hardware tools, chemical industry and other industries.

[0003] Stainless steel round bars require a clamping tool during the processing. When used, the existing clamping tool usually uses two sets of clamping mechanisms to clamp and fix the two ends of the stainless steel round bars. However, the two sets of clamping mechanisms are not convenient for synchronous operation, resulting in low clamping efficiency and affecting processing efficiency. For this reason, technical personnel in this field have proposed a clamping tool for stainless steel round bar processing to solve the problems raised in the above background. Utility Model Content

[0004] The purpose of the utility model is to provide a clamping tool for processing stainless steel round bars to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A pressing component is provided on the processing table and located above the V-shaped bracket, and is used to press down the top of the stainless steel round bar;

[0008] The transmission component is arranged between the movable rod and the movable frame, and is used to drive the movable rod to rotate around the fixed axis.

[0009] The fixed shaft is located in the middle of the movable rod. The pressing component includes a bracket installed in the middle of the processing table, a screw rod is threaded on the bracket, a pressing block is rotatably provided at the bottom end of the screw rod, two limiting rods slidably connected to the bracket are installed on the pressing block, and a rotating block is installed at the top end of the screw rod.

[0010] As a further solution of the present invention: a V-shaped groove is provided at the bottom of the lower pressing block.

[0011] As a further solution of the present invention: the transmission component includes a connecting seat installed on both sides of the bottom end of the movable frame, and a second rotating shaft is rotatably set on the connecting seat. The second rotating shaft is hinged to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the first rotating shaft, and the first rotating shaft is rotatably connected to the bottom end of the movable rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention places the stainless steel round bar on the V-shaped bracket, and then presses the top of the stainless steel round bar through the pressing component, thereby pushing the V-shaped bracket downward, so that the supporting slide plate will also move downward. The elastic force of the spring cooperates with the pressing component to initially clamp the middle part of the stainless steel round bar, and when the supporting slide plate moves downward, it will also drive the movable frame to move downward.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 5 , a clamping tool for processing stainless steel round bars, comprising a processing table 1, two supporting slides 3 are slidably provided in the middle of the processing table 1, a V-shaped bracket 2 is installed on the top of the supporting slide 3 for supporting the bottom of the stainless steel round bar, springs 5 connected to the processing table 1 are provided on both sides of the bottom of the V-shaped bracket 2, a movable frame 4 is installed on the bottom end of the supporting slide 3, two symmetrically distributed connecting grooves 6 are provided on both sides of the processing table 1, a fixed shaft 19 is rotatably provided in the connecting groove 6, the fixed shaft 19 is rotatably connected to the movable rod 7, and an arc-shaped splint 8 is installed on the top of the movable rod 7, and further comprising;

[0021] A pressing component is provided on the processing table 1 and is located above the V-shaped bracket 2, and is used to press down the top of the stainless steel round rod;

[0022] The transmission component is arranged between the movable rod 7 and the movable frame 4 and is used to drive the movable rod 7 to rotate around the fixed axis 19.

[0023] By placing the stainless steel round rod on the V-shaped bracket 2, and then pressing the top of the stainless steel round rod through the pressing component, the V-shaped bracket 2 is pushed downward, so that the supporting slide 3 will also move downward. The elastic force of the spring 5 and the pressing component can initially clamp the middle part of the stainless steel round rod, and when the supporting slide 3 moves downward, it will also drive the movable frame 4 to move downward. The transmission component can drive the movable rod 7 to rotate around the fixed axis 19, so that the arc-shaped clamping plate 8 on the movable rod 7 moves closer to the stainless steel round rod until the arc-shaped clamping plate 8 completes the clamping of both sides of the stainless steel round rod, thereby completing the entire clamping operation.

[0024] In one case of this embodiment, the fixed shaft 19 is located in the middle of the movable rod 7 , so that when the movable frame 4 moves downward, the transmission component can drive the movable rod 7 to rotate around the fixed shaft 19 .

[0025] In one case of this embodiment, the pressing component includes a bracket 13 installed in the middle of the processing table 1, a screw rod 14 is threaded on the bracket 13, a pressing block 15 is rotatably provided at the bottom end of the screw rod 14, and two limiting rods 17 slidingly connected to the bracket 13 are installed on the pressing block 15, and a rotating block 18 is installed at the top of the screw rod 14.

[0026] When in use, place the stainless steel round rod on the V-shaped bracket 2, rotate the rotating block 18, drive the screw rod 14 to rotate, and cooperate with the limit rod 17 to drive the lower pressure block 15 to move downward, so that the lower pressure block 15 can be against the top of the stainless steel round rod and push the stainless steel round rod to move downward. At the same time, the V-shaped bracket 2 will also move downward. During this process, the spring 5 will be gradually compressed. The elastic support force of the spring 5 on the V-shaped bracket 2 and the downward pressure of the lower pressure block 15 can be used to initially clamp the middle part of the stainless steel round rod.

[0027] In one case of this embodiment, a V-shaped groove 16 is provided at the bottom of the lower pressing block 15. The provision of the V-shaped groove 16 facilitates the lower pressing block 15 to stably rest against the top of the stainless steel round rod.

[0028] In one case of this embodiment, the transmission component includes a connecting seat 12 installed on both sides of the bottom end of the movable frame 4, and a second rotating shaft 11 is rotatably provided on the connecting seat 12. The second rotating shaft 11 is hinged to one end of the connecting rod 10, and the other end of the connecting rod 10 is rotatably connected to the first rotating shaft 9. The first rotating shaft 9 is rotatably connected to the bottom end of the movable rod 7.

[0029] When the downward pressure component applies downward pressure to the stainless steel round rod, it will push the V-shaped bracket 2 downward, so that the supporting slide 3 will also move downward, driving the movable frame 4 to move downward synchronously. In the process of the movable frame 4 moving downward, it will drive the connecting rod 10 to rotate around the second rotating shaft 11, and the connecting rod 10 will push the bottom of the movable rod 7 through the first rotating shaft 9, so that the movable rod 7 rotates around the fixed axis 19, so that the arc-shaped clamping plate 8 on the top of the movable rod 7 can clamp and fix the side walls of both ends of the stainless steel round rod.

[0030] When the pressing component exerts downward pressure on the stainless steel round rod, it will push the V-shaped bracket 2 downward, so that the supporting slide 3 will also move downward, driving the movable frame 4 to move downward synchronously. In the process of the movable frame 4 moving downward, it will drive the connecting rod 10 to rotate around the second rotating shaft 11, and the connecting rod 10 will push the bottom of the movable rod 7 through the first rotating shaft 9, so that the movable rod 7 rotates around the fixed shaft 19, so that the arc clamping plate 8 at the top of the movable rod 7 can clamp and fix the two end side walls of the stainless steel round rod.

[0031] Compared with the prior art, the present invention only requires placing the stainless steel round bar on the V-shaped bracket 2 and operating the pressing component to enable the arc clamps on both sides of the processing table 1 to clamp the two sides of the stainless steel round bar synchronously, with high clamping efficiency, thereby improving the overall processing efficiency of the stainless steel round bar.
