Detailed Embodiment

[0029] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the accompanying drawings. Among them, the accompanying drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, and are not used to limit the scope of the present utility model.

[0030] Please refer to Figures 1 - 5 , the present utility model provides a sawing machine tooling fixture, including:

[0031] Workbench 1;

[0032] Clamping mechanism 2, the clamping mechanism 2 includes a first driving member 21, a slideway 22, a pair of sliders 23 and a pair of second driving members 24. The slideway 22 is fixedly connected to the top of the workbench 1. The two sliders 23 are respectively slidably connected to the slideway 22. A plurality of arc rods 231 are respectively hinged to the tops of the two sliders 23, and a channel 232 is provided between each arc rod 231. The arc rods 231 on any one slider 23 are arranged opposite to the channels 232 on the other slider 23;

[0033] The first driving member 21 is located on one side of the two sliders 23 and is used to drive the two sliders 23 to move towards each other along the length direction of the slideway 22, so that the arc-shaped rods 231 on any one slider 23 are inserted into the channels 232 on the other slider 23;

[0034] The second driving member 24 is respectively located on one side of the two sets of arc-shaped rods 231 and is used to drive the two sets of arc-shaped rods 231 to rotate towards each other.

[0035] Specifically, the first driving member 21 drives the two sliders 23 to move towards each other or in opposite directions along the length direction of the slideway 22, and each arc-shaped rod 231 can be inserted into and withdrawn from the corresponding channels 232, so that the arc-shaped rods 231 can clamp pipe workpieces with different numbers or different thicknesses as the sliders 23 move. Then, the second driving member 24 rotates each arc-shaped rod 231, so that the arc-shaped rods 231 can press down the pipe workpieces, improving the stability of the pipe workpieces during the processing. There is no need to separately set a pressing mechanism above the pipe workpieces, and this solution has a higher clamping efficiency.

[0036] First, the first driving member 21 is started, and the second driving member 24 is started, so that there is a certain distance between the arc-shaped rods 231 on the two sliders 23; then, the pipe workpiece is placed on the slideway 22 between the two sliders 23; then, the first driving member 21 is started, driving the two sliders 23 to move towards each other until the arc-shaped rods 231 on the two sliders 23 clamp the pipe workpiece; finally, the second driving member 24 is started, driving each arc-shaped rod 231 to rotate towards each other, giving the pipe workpiece a downward pressing force to further fix the pipe workpiece.

[0037] It should be noted that in order not to affect the movement of the sliders 23 driving the arc-shaped rods 231, the top of the slideway 22 is in an open state. Therefore, the pipe workpiece is supported by the two side walls of the slideway 22.

[0038] Furthermore, in order to improve the support of the two side walls of the slideway 22, the two side walls of the slideway 22 are made thicker.

[0039] Further, in this embodiment, the first driving member 21 includes a screw rod 211 and a motor 212. Threaded holes 233 are formed in the side walls of the two sliders 23. The screw rod 211 is sleeved in the two threaded holes 233, and the motor 212 is located at the end of the screw rod 211 and is used to drive the screw rod 211 to rotate self. Specifically, the motor 212 adopts a servo motor 212. By using the forward and reverse rotation of the servo motor 212 to drive the screw rod 211 to rotate in different directions, the two sliders 23 can be moved towards each other or in opposite directions, thereby facilitating the placement of the pipe workpiece between the two sliders 23 and waiting for the two sliders 23 to approach and clamp.

[0040] Further, after the pipe workpiece is processed, the motor 212 is started, and the two sliders 23 move in opposite directions, and the respective arc-shaped rods 231 move away from each other, and the pipe workpiece is released from the fixed state.

[0041] Further, in this embodiment, the second driving member 24 includes a cylinder 241 and a hinge plate 242. The hinge plate 242 is fixedly connected to the bottom ends of the respective arc-shaped rods 231. The cylinder 241 is connected to the hinge plate 242. The cylinder 241 is used to drive the hinge plate 242 to rotate and drive the respective arc-shaped rods 231 to rotate. Specifically, the cylinder 241 adopts a single-axis cylinder 241. The horizontal planes where the respective hinge plates 242 are located form a certain angle with the tangent planes of the respective arc-shaped rods 231. The rotation directions of the two hinge plates 242 are always opposite. The fixed ends of the respective cylinders 241 are received in the sliders 23 and fixedly connected to the inner walls of the sliders 23. The movable ends of the cylinders 241 are hinged to the hinge plates 242, so that when the cylinders 241 are started, they can drive the respective hinge plates 242 to rotate upward, and further drive the respective arc-shaped rods 231 to rotate toward each other, so that the arc-shaped rods 231 not only have a clamping force, but also have a pressing force downward on the pipe workpiece, improving the stability of the pipe workpiece.

[0042] Further, after the pipe workpiece is processed, the cylinder 241 is started, the hinge plate 242 rotates downward, and the respective arc-shaped rods 231 rotate in a direction away from each other, and the pipe workpiece is released from the fixed state.

[0043] Further, in this embodiment, the inner walls of the opposite surfaces of the slideway 22 are both provided with chutes 221, and the outer walls of the opposite surfaces of the sliders 23 are both provided with protrusions 234. The two sliders 23 are respectively slidably embedded in the two chutes 221. Specifically, the chutes 221 and the protrusions 234 are used to ensure that the sliders 23 always move along the length direction of the slideway 22 and prevent the sliders 23 from deviating from the preset sliding trajectory.

[0044] Further, in this embodiment, a first slag discharge port 235 is provided at the bottom of the slider 23. Specifically, during the sawing process of the pipe workpiece, flying residues will be generated everywhere, and it is inevitable that residues will fall into the slider 23. The function of the first slag discharge port 235 is to clean the residues in the slider 23 into the slideway 22, which is convenient for the staff to uniformly remove the residues from the slideway 22.

[0045] Further, in this embodiment, a second slag discharge port 222 is provided on the side wall of the slideway 22. Specifically, the function of the second slag discharge port 222 is to facilitate the removal of the residues in the slideway 22 to the surface of the workbench 1, so as to facilitate the staff to further clean the residues.

[0046] Further, in this embodiment, a sloping plate 223 is provided on one side of the slideway 22. Specifically, the function of the sloping plate 223 is to guide the sawed pipe workpiece to slide along the length direction of the sloping plate 223 to a designated position.

[0047] Further, in this embodiment, a sawtooth mechanism 3 is provided above each arc-shaped rod 231. Specifically, after the pipe workpiece is fixed by the clamping mechanism 2, the sawtooth mechanism 3 is used to saw off the pipe workpiece.

[0048] Further, in this embodiment, a hinge frame 31 is provided at the top of the workbench 1, and one end of the sawtooth mechanism 3 is hinged to the hinge frame 31. Specifically, the sawtooth mechanism 3 is hinged to the workbench 1 through the hinge frame 31, which facilitates the sawtooth mechanism 3 to be lifted by the hinge frame 31, expands the operating space above each arc-shaped rod 231, and improves the convenience of operation for the staff.

[0049] Further, in this embodiment, a control box 32 is fixedly connected to the top of the sawtooth mechanism 3. Specifically, the control box 32 is used to control the operation of the sawtooth mechanism 3.

[0050] The specific working process of the present utility model is as follows: First, the motor 212 is started, the screw 211 rotates self, the air cylinder 241 is started, the hinge plate 242 rotates, so that the arc-shaped rods 231 on the two sliders 23 move and rotate in a direction away from each other, and thus a preset space for placing the pipe workpiece is left between the two sliders 23; then, the pipe workpiece is placed on the slideway 22 between the two sliders 23 and supported by the side walls of the slideway 22; then, the motor 212 is started to drive the two sliders 23 to move towards each other until the arc-shaped rods 231 on the two sliders 23 clamp the pipe workpiece; subsequently, the air cylinder 241 is started to drive each arc-shaped rod 231 to rotate towards each other, giving the pipe workpiece a downward pressing force to further fix the pipe workpiece; finally, the control box 32 is operated to control the sawtooth mechanism 3 to start processing the pipe workpiece.

[0051] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
