Description

Technical Field

[0001] This invention belongs to the field of sawing technology, and particularly relates to a sawing sampling device. Background Technology

[0002] In the metallographic structure testing and experimentation of disc-shaped metal materials, it is necessary to cut two symmetrical samples 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 cutting 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 cutting process, which changes the metallographic structure and affects the accuracy of the testing and experimental results. In addition, the positioning reliability of the disc-shaped metal material during the cutting process is poor, which makes it impossible to cut two completely identical samples, resulting in the failure to detect the metallographic structure at specific locations. Summary of the Invention

[0003] This invention provides a sawing and sampling device to achieve mechanized and rapid positioning and cutting of disc-shaped metal materials, thereby ensuring the accuracy of detection and experimental results.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: a sawing and sampling device, including a body, a base on the body, a saw driven by a first power device slidably mounted on the base, a slide driven by a second power device slidably mounted on the body on the sawing execution side of the saw, a positioning surface pre-cutting clamping mechanism and a sampling positioning and pressing mechanism are arranged sequentially on the slide, and a sawing avoidance groove is provided on the slide corresponding to the sawing position on the positioning surface pre-cutting clamping mechanism and the sampling positioning and pressing mechanism.

[0005] As an improvement, a worktable driven by a first linear drive element is slidably mounted on the machine body, and at least two sets of slides driven by the second power device are slidably mounted on the worktable. Each slide is provided with the positioning surface pre-cutting clamping mechanism and the sampling positioning clamping mechanism.

[0006] As a further improvement, the positioning surface pre-cut clamping mechanism includes a first mounting seat disposed on the slide, the first mounting seat is provided with a first support plate, the first mounting seats located on one side of the first support plate are all provided with a stop block, the first mounting seats located on the other periphery of the first support plate are all provided with a support seat, and each support seat is provided with a top pressure plate driven by a second linear drive element.

[0007] The sawing clearance groove extends to the first mounting base, wherein a support base is correspondingly provided with the sawing clearance groove, and a sawing gap is provided between the first support plate and the support base, the sawing gap communicating with the sawing clearance groove.

[0008] As a further improvement, a protruding support block is formed on the support base located on one side of the saw cut, and the support block is coplanar with the first support plate.

[0009] As a further improvement, both top pressure plates are provided with guide rods, which are slidably mounted on the support base;

[0010] One of the top pressure plates is equipped with a top block.

[0011] As a further improvement, the slide is provided with multiple positioning slots, and the support is positioned and installed in the positioning slots.

[0012] As a further improvement, the length of the positioning groove is greater than the length of the support base.

[0013] As a further improvement, the sampling positioning and clamping mechanism includes a second mounting base disposed on the slide, the second mounting base being provided with a second support plate, and the sawing clearance groove extending to the second mounting base and the second support plate;

[0014] A second stop is provided on the second mounting base located on both sides of the sawing clearance groove. A positioning top plate driven by a third linear drive element is provided on the second mounting base opposite to the second stop. The positioning top plate is provided with a limiting slot.

[0015] The second mounting base is provided with a bracket that spans the positioning top plate, and the bracket is provided with a pressure block driven by a fourth linear drive element.

[0016] As a further improvement, the bracket is provided with two sets of pressure blocks driven by the fourth linear drive element, and symmetrically distributed on both sides of the sawing clearance groove.

[0017] As a further improvement, the machine body is provided with a material trough, and a conveyor line is provided on the machine body located below the material trough, with a material cart connected to the end of the conveyor line.

[0018] After adopting the above technical solution, the effect of the present invention is as follows:

[0019] The sawing sampling device includes a body with a base on it. A saw driven by a first power unit is slidably mounted on the base. A slide driven by a second power unit is slidably mounted on the body on the sawing execution side of the saw. A positioning surface pre-cutting clamping mechanism and a sampling positioning and pressing mechanism are arranged sequentially on the slide. Sawing clearance grooves are provided on the slides corresponding to the sawing positions on the positioning surface pre-cutting clamping mechanism and the sampling positioning and pressing mechanism. Based on the above structure, in operation, the sawing sampling device first places the disc-shaped metal material to be sampled on the positioning surface pre-cutting clamping mechanism for positioning. After the first power unit moves the first power unit to the sawing position, the second power unit drives the positioning surface pre-cutting clamping mechanism on the slide to the sawing position. Then, the first power unit drives the sawing machine to move and cut off part of the material. At this time, the disc-shaped metal material presents a positioning plane. After that, the sawing machine and the positioning surface pre-cutting clamping mechanism return to their original positions. Then, the disc-shaped metal material with part of the material cut off is transferred to the sampling positioning and pressing mechanism for positioning and pressing. Then, the second power unit drives the sampling positioning and pressing mechanism on the slide to the sawing position. Then, the sawing machine performs multiple rapid sawings to complete the sampling of multiple samples.

[0020] In summary, this sawing and sampling equipment enables mechanized positioning, positioning surface sawing, and sample cutting of disc-shaped metal materials. The positioning and cutting are fast and accurate, without affecting the metallographic structure of the disc-shaped metal materials themselves, effectively ensuring the accuracy of the detection and experimental results.

[0021] Because the machine body is slidably mounted with a worktable driven by a first linear drive element, and at least two sets of slides driven by a second power device are slidably mounted on the worktable, each slide is equipped with a positioning surface pre-cutting clamping mechanism and a sampling positioning clamping mechanism. Thus, during operation, the positioning surface pre-cutting clamping mechanism and the sampling positioning clamping mechanism on each slide are connected by the sliding of the worktable, ensuring the continuity of work and improving sampling efficiency.

[0022] The positioning surface pre-cutting clamping mechanism includes a first mounting seat set on a slide, a first support plate on the first mounting seat, a stop block on each of the first mounting seats on one side of the first support plate, and support seats on the other first mounting seats around the first support plate. Each support seat has a top pressure plate driven by a second linear drive element. The sawing clearance groove extends to the first mounting seat, with one support seat corresponding to the sawing clearance groove, and a sawing gap between the first support plate and the support seat. The sawing gap communicates with the sawing clearance groove. Thus, during operation, the first support plate holds the disc-shaped metal material and ensures its horizontality. Then, the cooperation of the stop block and the top pressure plate driven by the second linear drive element achieves positioning of the disc-shaped metal material around its perimeter. After sawing, the sawing gap and the sawing clearance groove avoid the saw blade during operation. The structure is simple, has a good positioning effect on disc-shaped metal materials, and a fast positioning speed.

[0023] Because the support base located on one side of the sawing kerf has a protruding support block, and the support block is set on the same plane as the first support plate, the disc-shaped metal material is supported by the support block when the positioning surface is sawn and formed, so as to ensure the horizontality of the positioning surface sawing and forming.

[0024] Guide rods are provided on both top pressure plates, and the guide rods are slidably installed on the support base; one of the top pressure plates is equipped with a top block, and the guide rods ensure the linearity and stability of the movement of the top pressure plate, which is beneficial to improving the positioning effect of disc-shaped metal materials; the top pressure plate is used to meet the positioning of large-diameter disc-shaped metal materials, and the top block is used to meet the positioning of small-diameter disc-shaped metal materials.

[0025] Because the slide has multiple positioning slots, the support is positioned and installed in the positioning slots, which facilitates quick and accurate installation of the support.

[0026] Since the length of the positioning groove is greater than the length of the support base, the installation position of the support base in the positioning groove can be easily adjusted according to the working requirements under different working conditions.

[0027] The sampling positioning and clamping mechanism includes a second mounting base mounted on a slide, a second support plate on the second mounting base, and a sawing clearance groove extending to the second mounting base and the second support plate. Second stops are located on both sides of the sawing clearance groove on the second mounting base, and a positioning top plate driven by a third linear drive element is located on the second mounting base opposite to the second stops. A limiting slot is located on the positioning top plate. A bracket spanning the positioning top plate is located on the bracket, and a pressure block driven by a fourth linear drive element is located on the bracket. During operation, the second support plate holds the disc-shaped metal material (with a sawn positioning surface) and ensures its horizontality, while simultaneously abutting the positioning surface against the second stop. Then, the third linear drive element drives the positioning top plate close to the disc-shaped metal material, causing the limiting slot to cover and position it. Finally, the fourth linear drive element drives the pressure block to clamp it. Afterward, the sawing machine performs sawing and sampling. The positioning and clamping are fast and reliable, which helps improve the sampling effect.

[0028] Because the support is equipped with two sets of pressure blocks driven by the fourth linear drive element and symmetrically distributed on both sides of the sawing clearance groove, the sawing machine can cut from the middle of the disc-shaped metal material first, and then cut once on each side during the positioning and clamping process, thus completing the cutting and sampling of two samples. The consistency of the samples is high, which solves the problem of not being able to detect metallographic structures in specific locations.

[0029] Because the machine body is equipped with a material trough, and a conveyor line is located on the machine body below the material trough, and a material cart is connected to the end of the conveyor line, the iron filings generated during the sawing process are collected in a concentrated manner through the material trough. Then, the iron filings are transferred through the cooperation of the conveyor line and the material cart, without the need for human intervention, which reduces the labor burden of the workers.
