[0040] See also Figure 1-11 The utility model provides a technical solution: a longitudinal cutting tool for strip and pipe test pieces, comprising a workbench 1, a fixture 2 and a cutting machine 13 installed on the workbench 1, the fixture 2 comprising a mounting block 21 and two rows of slide bars 22 respectively arranged on both sides of the mounting block 21, a placement hole 211 for the clamped piece to pass through is opened in the middle of the mounting block 21, the two rows of slide bars 22 respectively extend from both sides of the mounting block 21 into the placement hole 211, each of the slide bars 22 is slidably connected to the mounting block 21, and each of the slide bars 22 is sleeved with a spring 23, one end of the spring 23 is fixedly connected to the mounting block 21, and the other end extends to one side of the placement hole 211 and is fixedly connected to the slide bar 22, and when the spring 23 is in a naturally extended state, the ends of the two rows of slide bars 22 abut against each other in the placement hole 211;
[0041] A locking mechanism for fixing the position of the sliding rod 22 is provided between each of the sliding rods 22 and the mounting block 21 .
[0042] The mounting block 21 is a hollow structure. All the slide bars 22 are arranged inside the mounting block 21. One end of the slide bar 22 penetrates the side wall of the mounting block 21 near the placement hole 211 and extends into the placement hole 211. The side wall is provided with a through hole that slides with the slide bar 22 to limit the free swing of the slide bar 22. The two rows of slide bars 22 on both sides of the mounting block 21 are symmetrically arranged and arranged in a linear array in the vertical direction, so that the clamping points on both sides of the clamp 2 exert a relatively symmetrical force on the workpiece to be cut, so that the workpiece to be cut can easily return to the center position between the slide bars 22 on both sides; both sides of the interior of the mounting block 21 are provided with partitions 213, and the springs 23 are sleeved on the slide bars 22 and the two ends are respectively connected to the partitions 213 and the slide bars 22, and the springs 23 are used to provide pressure for the slide bars 22 to squeeze the workpiece to be cut. Among them, the model of the cutting machine 13 is Olihu 305.
[0043] When in use, when the workpiece to be cut is inserted into the placement hole 211, the workpiece to be cut squeezes and pushes the end of the sliding rod 22 located in the placement hole 211, so that the sliding rod 22 moves away from the placement hole 211, and the sliding rod 22 squeezes the corresponding spring 23. At the same time, the sliding rod 22 is pushed against the surface of the workpiece to be cut under the reaction force of the spring 23, so that one end of multiple sliding rods 22 located in the placement hole 211 forms a hole similar to the shape of the workpiece to be cut, so as to realize the pre-clamping function of the workpiece to be cut; the sliding rod 22 is then fixed to the mounting block 21 through a locking mechanism to clamp and fix the workpiece to be cut on the workbench 1; by setting a plurality of freely movable clamping points on the clamp 2, the clamping and fixing of the workpieces to be cut of different shapes can be realized; finally, the workpiece to be cut is cut by the cutting machine 13 installed on the processing table, so as to improve the processing efficiency of the workpiece to be cut to a certain extent.
[0044] In this embodiment, the locking mechanism includes a limit block 24 fixedly connected to the mounting block 21 and a first rotating shaft 25 rotatably connected to the mounting block 21. The limit block 24 is provided with an elastic sheet 241 inclined toward the corresponding slide bar 22. There is a gap between the elastic sheet 241 and the outer surface of the slide bar 22 in a natural state.
[0045] The first rotating shaft 25 is threadedly connected with a push block 26 , and the push block 26 is used to squeeze the end of the elastic sheet 241 to bend toward the sliding rod 22 . The mounting block 21 is provided with a driving part for driving the first rotating shaft 25 to rotate.
[0046] The limit block 24 is in the shape of a circular tube and is sleeved on the slide rod 22. One end of the limit block 24 is fixedly connected to the side of the partition 213 away from the placement hole 211. The other end of the limit block 24 is provided with a plurality of elastic sheets 241 arranged in a circular shape. When the plurality of elastic sheets 241 are in a naturally stretched state, the open ends are gathered toward the slide rod 22, and there is a gap between the plurality of elastic sheets 241 and the slide rod 22, so that the slide rod 22 can move normally; the first rotating shaft 25 is arranged between the elastic sheet 241 and the outer wall of the mounting block 21. It is a tubular structure and is also sleeved on the slide rod 22; the push block 26 is threadedly engaged with the side of the first rotating shaft 25 close to the elastic sheet 241, and the mounting block 21 is provided with a limit groove 212 for limiting the rotation of the push block 26, and the outer wall of the push block 26 is fixedly connected with a slide bar 261 that slides and fits in the limit groove 212.
[0047] When in use, the first rotating shaft 25 is rotated forward, and the external thread on the first rotating shaft 25 pushes the push block 26 to move in the direction of the elastic sheet 241. The inner wall of the push block 26 squeezes the elastic sheet 241, so that the multiple elastic sheets 241 on the limit block 24 gather toward the slide rod 22 until the end of the elastic sheet 241 contacts the slide rod 22. Under the action of the friction force between the elastic sheet 241 and the slide rod 22, the movement of the slide rod 22 is limited, so that the slide rod 22 can stably clamp the workpiece to be cut.
[0048] In this embodiment, the driving part includes two chains 27 and two second rotating shafts 28 arranged on the left and right sides of the mounting block 21, and the two second rotating shafts 28 are both rotatably connected to the mounting block 21;
[0049] Two meshing gears 29 are provided between the two second rotating shafts 28, and the two gears 29 are fixedly connected to one end of the two second rotating shafts 28 respectively;
[0050] The two second rotating shafts 28 are both fixedly connected with a driving sprocket 281 meshing with the adjacent chains 27 , and each of the first rotating shafts 25 is fixedly connected with a driven sprocket 251 meshing with the adjacent chains 27 .
[0051] When in use, one of the second rotating shafts 28 is rotated forward, and the two gears 29 between the two second rotating shafts 28 are used to drive the other second rotating shaft 28 to rotate forward, so as to achieve the purpose of rotating the chains 27 on both sides at the same time; the second rotating shaft 28 drives the chain 27 to move through the driving sprocket 281, so that all the driven sprockets 251 engaged with the chain 27 drive the corresponding first rotating shaft 25 to rotate forward, and then the push block 26 on the first rotating shaft 25 moves toward the direction of the elastic sheet 241 to squeeze the elastic sheet 241, and finally achieves the locking work of all the sliding rods 22 at the same time.
[0052] In this embodiment, a turntable 282 is disposed outside the mounting block 21 to provide power for the second rotating shaft 28 , and the other end of the second rotating shaft 28 penetrates through the side wall of the mounting block 21 and extends into the outside of the mounting block 21 to be fixedly connected to the turntable 282 .
[0053] By arranging the turntable 282 outside the mounting block 21, it is convenient to manually rotate the turntable 282 to drive the second rotating shaft 28 to rotate, and finally fix the sliding rod 22, which is simple and convenient to operate.
[0054] In this embodiment, a slide groove 11 is provided at the lower portion of the workbench 1, and a slider 12 is slidably fitted in the slide groove 11. The slider 12 is fixedly connected to a cutting machine 13. A cutting groove 14 is provided on the top wall of the workbench 1 along the length direction of the slide groove 11. The saw blade 131 of the cutting machine 13 extends from the cutting groove 14 to the top of the workbench 1.
[0055] By fixing the fixed end of the cutting machine 13 on the slider 12, the cutting machine 13 can move in the slide groove 11 together with the slider 12, thereby realizing the cutting processing of longer pieces to be cut. At the same time, the slide groove 11 has a guiding function, so that the cutting processing of the pieces to be cut is more accurate, and the user does not need to have high cutting technology.
[0056] In this embodiment, a motor 16 fixedly connected to the workbench 1 and a screw rod 15 transmission-connected to the output end of the motor 16 are also provided below the workbench 1. The middle part of the screw rod 15 is threadedly connected to the slider 12, and the screw rod 15 is rotationally connected to the slide groove 11.
[0057] The motor 16 is arranged at one end of the chute 11, and one end of the screw rod 15 penetrates the side wall of the chute 11 and extends out of the chute 11 to be fixedly connected to the output end of the motor 16. The motor 16 drives the screw rod 15 to rotate, and then the external thread of the screw rod 15 pushes the slider 12 to move in the chute 11, so that the motor 16 can control the cutting machine 13 to move at a uniform speed to smoothly cut the workpiece to be cut. The model of the motor 16 is 180M-21520C5-E.
[0058] In this embodiment, one end of the slide rod 22 close to the gear 29 is in a ball head shape.
[0059] One end of the slide bar 22 close to the gear 29 is set to be in a ball head shape, so that the workpiece to be cut can squeeze and push the slide bar 22 to move, thereby facilitating the insertion of the workpiece to be cut into the placement hole 211, thereby facilitating the clamping of the workpiece to be cut.
[0060] In this embodiment, a positioning block 31 is fixedly connected to the workbench 1 on one side of the clamp 2, and a centering hole 32 is provided on the positioning block 31 along the direction of the cutting groove 14. The positioning block 31 is provided with a movable plate 33 slidingly connected to the positioning block 31 and a bolt 34 rotatably connected to the movable plate 33, and the bolt 34 is threadedly connected to the positioning block 31.
[0061] The interior of the positioning block 31 is provided with a rectangular cavity, and the movable plate 33 is slidably fitted in the cavity to guide the movement of the movable plate 33. The centering hole 32 is an equilateral triangular hole centered on the plane of the movement trajectory of the saw blade 131, and passes through the two side walls of the positioning block 31 in sequence. The bottom surface of the movable plate 33 and the upper side surface of the centering hole 32 are parallel to the horizontal plane; after the workpiece to be cut is inserted into the centering hole 32, the bolt 34 is rotated forward so that the bolt 34 moves with the movable plate 33 toward the direction of the workpiece to be cut under the push of the internal thread on the positioning block 31, so that the workpiece to be cut is pre-clamped by the regular triangular prism space formed by the bottom surface of the movable plate 33 and the two lower side surfaces of the centering hole 32, so that the workpiece to be cut is stably located on a certain horizontal plane, avoiding the workpiece to be cut from being skewed when being clamped and fixed by the clamp 2, thereby affecting the clamp 2 to smoothly clamp and fix the workpiece to be cut.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
