DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-4 A mechanical processing positioning tool shown in the figure includes a positioning frame 1, a clamping plate 2 for clamping a workpiece is symmetrically arranged on the top of the positioning frame 1, a positioning cylinder 3 is arranged on one side of the clamping plate 2, a moving component is arranged on the bottom of the clamping plate 2, and a replacement component for replacing the positioning cylinder 3 is arranged at the connection between the clamping plate 2 and the positioning cylinder 3, and the replacement component includes a trapezoidal slider 4 fixedly connected to one side of the positioning cylinder 3, a trapezoidal slide groove 5 is opened on the side of the clamping plate 2 close to the positioning cylinder 3, the trapezoidal slider 4 is inserted and connected inside the trapezoidal slide groove 5, and a limiting member for limiting the trapezoidal slider 4 from moving out of the trapezoidal slide groove 5 is arranged at the connection between the trapezoidal slider 4 and the trapezoidal slide groove 5.

[0021] It should be noted that when the tubular workpiece needs to be positioned, the two clamps 2 are driven by the moving assembly to clamp the tubular workpiece. However, during the clamping process, the tubular workpiece moves vertically between the two clamps 2. The positioning cylinder 3 is used to penetrate into the interior of the tubular workpiece. The positioning cylinder 3 is driven by the fixed position to limit the two ends of the tubular workpiece respectively, so that the tubular workpiece cannot move in the vertical direction, thereby positioning the tubular workpiece; the cross-sections of the set trapezoidal slider 4 and the trapezoidal slide 5 are both set to be isosceles trapezoids. When in use, the trapezoidal slider 4 is inserted through the top of the trapezoidal slide 5. The isosceles trapezoidal design prevents the trapezoidal slider 4 from moving out of the trapezoidal slide 5 from the horizontal square, so that it can only move vertically in the trapezoidal slide 5. The designed limiting member is used to limit the vertical movement of the trapezoidal slider 4, so that the trapezoidal slider 4 is fixed in the trapezoidal slide 5 by the design of the isosceles trapezoid and the limiting member.

[0022] Furthermore, when the inner diameter of the tubular workpiece to be processed does not match the positioning cylinder 3 on one side of the clamp 2, the trapezoidal slider 4 on one side of the positioning cylinder 3 slides out from the trapezoidal slide groove 5 opened on one side of the clamp 2, and the positioning cylinder 3 that matches the inner wall of the tubular workpiece is found again, and the trapezoidal slider 4 fixedly connected to one side of the positioning cylinder 3 slides into the trapezoidal slide groove 5 again, and the trapezoidal slider 4 is fixed in the trapezoidal slide groove 5 by a limiting member, thereby completing the replacement of the positioning cylinder 3, thereby avoiding the situation where the pipe cannot be clamped and positioned.

[0023] Specifically, the limiting member includes a slot 6 opened on one side of the trapezoidal slider 4, a block 7 is clamped inside the slot 6, the block 7 is inserted and connected to the inner wall of one side of the trapezoidal slide groove 5, and the end of the block 7 away from the slot 6 is fixedly connected to a connecting plate 9 for moving the slot 6.

[0024] It should be noted that the provided block 7 and the slot 6 are used to fix the trapezoidal slider 4 in the trapezoidal slide groove 5. The provided block 7 is inserted and connected to the inner wall of one side of the trapezoidal slide groove 5, and is restricted by the inner wall of the trapezoidal slide groove 5 so that it cannot move in the vertical direction.

[0025] Furthermore, when the trapezoidal slider 4 needs to be fixed in the trapezoidal slide groove 5, the block 7 is driven to move through the connecting plate 9, and the block 7 is moved into the groove 6 opened on one side of the trapezoidal slider 4. The movement of the trapezoidal slider 4 is restricted by the block 7 that cannot move in the vertical direction. When the trapezoidal slider 4 needs to be moved, the block 7 is moved out of the groove 6 to remove the restriction on the trapezoidal slider 4.

[0026] Specifically, the side of the clamp plate 2 away from the trapezoidal slider 4 is fixedly connected to the fixed frame 8, the connecting plate 9 is inserted and connected inside the fixed frame 8, the side of the connecting plate 9 away from the slot 6 is fixedly connected to the spring 10, and one end of the spring 10 away from the connecting plate 9 is fixedly connected to the inner wall of one side of the fixed frame 8.

[0027] Specifically, a connecting rod 11 is inserted and connected in the middle of the spring 10, one end of the connecting rod 11 is fixedly connected to one side of the connecting plate 9, the connecting rod 11 is inserted and connected to the inner wall of one side of the fixed frame 8, and the end of the connecting rod 11 away from the connecting plate 9 is fixedly connected to a movable plate 12 for moving the connecting rod 11.

[0028] It should be noted that the spring 10 is used to push the connecting plate 9 in a direction away from the spring 10 , and the connecting rod 11 and the moving plate 12 are used to pull the connecting plate 9 toward one side of the spring 10 .

[0029] Furthermore, when it is necessary to move the block 7 out of the slot 6, the connecting rod 11 is driven to move by the movable plate 12, and the connecting plate 9 and the block 7 on one side of the connecting plate 9 are driven to move toward the side away from the slot 6 by the connecting rod 11. When the connecting plate 9 moves away from the block 7, the connecting plate 9 squeezes the spring 10 to cause it to deform. When the movement of the movable plate 12 is released, the spring 10 restores its deformation and pushes the connecting plate 9 and the block 7 toward the side away from the spring 10.

[0030] Specifically, a drop hole 13 for dropping debris is opened on the inner wall of the bottom end of the positioning frame 1.

[0031] It should be noted that the blanking hole 13 is used to prevent waste from falling into the positioning frame 1 after mechanical processing of the tubular workpiece. After use, the positioning frame 1 is blown by a fan to blow the waste out of the positioning frame 1 through the blanking hole 13.

[0032] Specifically, a bidirectional screw 14 is provided between the inner walls on both sides of the positioning frame 1 , and the bidirectional screw 14 is threadedly inserted and connected to the bottom of the clamping plate 2 . A limiting member for limiting the rotation of the clamping plate 2 is provided inside the positioning frame 1 .

[0033] Specifically, the limiting member includes a limiting rod 15 fixedly connected between the inner walls on both sides of the positioning frame 1 , and the limiting rod 15 is inserted and connected to the bottom of the clamping plate 2 .

[0034] It should be noted that the limit rod 15 and the bidirectional screw 14 are both inserted and connected at the bottom of the clamp 2, and the front and back sides of the bottom of the clamp 2 are restricted so that it cannot rotate. The threads on the bidirectional screw 14 are symmetrically arranged, and the two clamps 2 are symmetrically threaded on both sides of the bidirectional screw 14, so that the two clamps 2 that cannot rotate are driven to move in different directions by rotating the bidirectional screw 14, thereby completing the clamping, positioning and release of the workpiece; a motor for rotating the bidirectional screw 14 is arranged at one end of the bidirectional screw 14, and a bearing seat for supporting the bidirectional screw 14 is arranged at the other end.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
