Description

Technical Field

[0001] This utility model belongs to the field of sawing technology, and in particular relates to a positioning sawing device. Background Technology

[0002] In the metallographic structure testing and experimentation of disc-shaped metal materials, two symmetrical samples need to be cut for testing and experimentation. The current sampling method is: the staff manually scribbles lines on the disc-shaped metal material and then saws it. The sawing speed is slow, which not only affects the work efficiency, but also causes the temperature of the disc-shaped metal material to rise during the slow sawing process, which changes the metallographic structure and affects the accuracy of the test and experimental results. In addition, the positioning reliability of the disc-shaped metal material is poor during the sawing process, and multiple positioning and multiple feeding sawing operations are required, which makes it impossible to cut two identical samples, resulting in the failure to detect the metallographic structure at specific locations. Utility Model Content

[0003] This utility model provides a positioning sawing device to achieve mechanized and rapid positioning and sawing of disc-shaped metal materials, and to achieve the purpose of completing multiple sawing operations with one positioning and ensuring sampling consistency.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a positioning sawing device, including a base, on which a sawing machine driven by a first power device is slidably mounted, and a mounting seat is provided on the sawing execution side of the sawing machine. The mounting seat is provided with a positioning top plate driven laterally by a first linear drive element, and the positioning top plate is provided with a positioning slot.

[0005] Two blocks are provided at the end of the mounting base located in the positioning direction of the positioning top plate, and a first clearance groove is provided between the two blocks, the first clearance groove extending to the mounting base;

[0006] The mounting base is provided with a gantry frame that spans the positioning top plate. The gantry frame is provided with two brackets. Each bracket is slidably mounted with a pressure block driven vertically by a second linear drive element. The pressure block and the stop block are arranged in a one-to-one correspondence.

[0007] As an improvement, both of the brackets are provided with grooves on their sides that are close to each other. A guide rail mounted on the bracket is arranged in the groove, and a slide plate driven vertically by a second linear drive element is slidably mounted on the guide rail. The pressure block is disposed on the slide plate.

[0008] As a further improvement, the base is a wedge-shaped structure, and the sawing machine is slidably mounted on the base; the bracket has an inclined surface on the side near the sawing machine.

[0009] The gantry frame is provided with a second clearance groove, which is located between the two sliding plates.

[0010] As a further improvement, the mounting base is provided with a material support base that abuts against the stop block, and the first clearance groove also extends to the material support base.

[0011] As a further improvement, the mounting base also has a support plate for supporting the positioning top plate, the support plate being arranged between the material support base plate and the first linear drive element.

[0012] After adopting the above technical solution, the effect of this utility model is:

[0013] Because the positioning sawing device includes a base, on which a saw driven by a first power device is slidably mounted, and a mounting seat is provided on the sawing execution side of the saw, with a positioning top plate driven laterally by a first linear drive element on the mounting seat, and a positioning slot on the positioning top plate; two stops are provided at the end of the mounting seat in the positioning direction of the positioning top plate, with a first clearance groove between the two stops extending to the mounting seat; a gantry frame spanning the positioning top plate is provided on the mounting seat, with two supports on the gantry frame, each support having a pressure block driven vertically by a second linear drive element slidably mounted on it, with the pressure block and the stop block corresponding one-to-one; based on the above structure, the positioning sawing device... In the process, firstly, part of the disc-shaped metal material to be sampled is sawn off to form a positioning plane. Then, the material with the positioning plane is moved to the mounting base and the positioning plane abuts against two stops. Next, the first linear drive element drives the positioning top plate to approach the material and the positioning slot pushes and positions it in a covering (covering the arc-shaped surface of the material) manner. Then, the second linear drive element drives the pressure block to press the material tightly. Then, the first power device drives the sawing machine to move towards the pressed material. Then, the sawing machine repeatedly feeds three times and completes the sawing and sampling of two samples. During the sawing process, the first clearance groove is used for clearance.

[0014] In summary, this positioning and sawing device enables mechanized positioning, pressure application, and sample cutting of disc-shaped metal materials. The positioning and sawing are fast, accurate, and highly reliable, without affecting the metallographic structure of the disc-shaped metal materials themselves, effectively ensuring the accuracy of testing and experimental results. At the same time, it allows multiple sawing operations to be completed in a single positioning, pressing, and process, ensuring the consistency of the sample and solving the problem of not being able to detect the metallographic structure at specific locations.

[0015] Since the two supports are provided with grooves on the side that is close to each other, and guide rails mounted on the supports are arranged in the grooves, and a sliding plate driven vertically by a second linear drive element is slidably mounted on the guide rails, and the pressure block is set on the sliding plate, the above structure ensures the linearity of the movement of the pressure block, as well as the reliability and stability of the pressure block applying pressure to the disc-shaped metal material to be sawed and sampled.

[0016] Because the base is a wedge-shaped structure, the sawing machine is tilted and slidably mounted on the base; the bracket has an inclined surface on the side near the sawing machine; the gantry is provided with a second clearance groove, which is located between the two slide plates. Thus, the above structure not only does not affect the normal sawing operation, but also effectively reduces the horizontal displacement of the sawing machine, which is conducive to the miniaturization of the equipment and the reduction of space occupation.

[0017] Because the mounting base is provided with a material support plate that abuts against the stop block, and the first clearance groove also extends to the material support plate, the disc-shaped metal material to be sawed and sampled is supported by the high-precision material support plate during operation to ensure its horizontality and sawing and sampling accuracy.

[0018] Since the mounting base also has a support plate for supporting the positioning top plate, the support plate is arranged between the material support base plate and the first linear drive element. Thus, during the movement of the positioning top plate and the application of positioning jacking force to the disc-shaped metal material to be sawed and sampled, the support plate supports the positioning top plate, ensuring the smooth movement of the positioning top plate and the stability during the application of positioning jacking force, and avoiding shaking during the application of positioning jacking force, which would affect the positioning effect of the disc-shaped metal material to be sawed and sampled.
