A concrete core sample grinding device

Abstract

This application relates to the field of concrete core sample processing technology, and discloses a concrete core sample grinding device, including a support plate, a support platform, a linear moving module, a rotary motion module, a rotating plate, a support base, a first rotating shaft, cutting blades, and a grinding disc. In use, driven by an external force, the first rotating shafts on both sides rotate, which in turn drives the cutting blades and grinding discs on both sides to rotate synchronously. Driven by the rotary motion modules on both sides, both ends of the concrete core sample can be cut and ground simultaneously. Driven by the linear moving modules on both sides, the cutting and grinding amounts at both ends of the concrete core sample, as well as the feed rate during cutting and grinding, can be adjusted to complete the cutting and grinding work. Since the rotation of the cutting blades and grinding discs on both sides is achieved by driving the first rotating shafts on both sides, the number of driving sources is reduced.

[0036] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a concrete core sample grinding device, including a support plate 10, a support platform 20, a linear moving module 30, a rotary motion module 40, a rotating plate 50, a support base 60, a first rotating shaft 70, a cutting blade 80, and a grinding disc 90. The support plate 10 is used to abut against the ground or a tabletop, thereby supporting the entire device. The support platform 20 is installed on the top surface of the support plate 10 and is used to support and position the concrete core sample. The linear moving module 30 is installed on the top surface of the support plate 10, located on both sides of the support platform 20 along the length of the support plate 10. The moving ends of both linear moving modules 30 move along the width and length of the support plate 10, and are used to drive connected components to move along the width and length of the support plate 10. The rotary motion module 40 is respectively installed on the moving ends of the two linear moving modules 30, and moves under the drive of the two linear moving modules 30. The axes of the rotating ends of the two rotating motion modules 40 are parallel to the plane of the support plate 10, and are used to drive the connected components to rotate around their axes. Rotating plates 50 are respectively installed on the rotating ends of the two rotating motion modules 40, and rotate under the drive of the two rotating motion modules 40. Support seats 60 are respectively installed on the top surfaces of the two rotating plates 50, and are used to support and install rotatable first rotating shafts 70. The first rotating shafts 70 are rotatably inserted through the two support seats 60, and the axes of the two first rotating shafts 70 are both in plane to the plane of the support plate 10, and are used to support and install cutting discs 80 and grinding discs 90, respectively. Cutting discs 80 are respectively installed at one end of the two first rotating shafts 70, and rotate under the drive of the two first rotating shafts 70. Grinding discs 90 are respectively installed at the other end of the two first rotating shafts 70, and also rotate under the drive of the two first rotating shafts 70. The two first rotating shafts 70 can be controlled to rotate, so as to drive the cutting discs 80 and grinding discs 90 on the same side to rotate, respectively.

[0037] This embodiment of the invention provides a concrete core sample grinding device. Driven by an external force, the first rotating shafts 70 on both sides rotate, which in turn drives the cutting blades 80 and grinding discs 90 on both sides to rotate synchronously. Driven by the rotating motion modules 40 on both sides, the rotating plates 50 on both sides rotate, ultimately causing the cutting blades 80 or the grinding discs 90 to face each other. When the cutting blades 80 face each other, both ends of the concrete core sample can be cut simultaneously. When the grinding discs 90 face each other, both ends of the concrete core sample can be ground simultaneously. Driven by the linear movement modules 30 on both sides, the rotating motion modules 40 on both sides move along the length and width of the support plate 10, ultimately causing the cutting blades 80 and grinding discs 90 on both sides to move along the length and width of the support plate 10. When the cutting blades 80 and grinding discs 90 move along the length of the support plate 10, the cutting and grinding amounts at both ends of the concrete core sample can be adjusted. When the cutting blades 80 and grinding discs 90 on both sides move along the length of the support plate 10, the feed rate for cutting and grinding at both ends of the concrete core sample can be adjusted, thus completing the cutting and grinding work. Furthermore, by driving the first rotating shafts 70 on both sides to rotate, the rotation function of the cutting blades 80 and grinding discs 90 on both sides can be realized, reducing the number of drive sources.

The two rotary motion modules 40 are respectively installed on the top surface of the two movable plates 33.

[0041] In this embodiment, controlling the operation of the first electric push rods 34 on both sides allows the second bases 32 on both sides to move along the width direction of the support plate 10 under the guidance and support of the first guide rails and first sliders on both sides, ultimately driving the cutting discs 80 and grinding discs 90 on both sides to move along the width direction of the support plate 10. Controlling the operation of the second electric push rods 35 on both sides allows the moving plates 33 on both sides to move along the length direction of the support plate 10 under the guidance and support of the second guide rails and second sliders on both sides, ultimately driving the cutting discs 80 and grinding discs 90 on both sides to move along the length direction of the support plate 10.
