Description

Technical Field

[0001] This utility model relates to the field of diamond wire cutting technology, specifically to a digital tensioning mechanism for diamond wire cutting. Background Technology

[0002] Diamond wire sawing offers advantages such as narrow kerf, high efficiency, good slice quality, and the ability to cut curved surfaces, making it a widely adopted cutting technology. During the use of diamond wire saws, especially when replacing new cutting wire, a tensioning mechanism is employed. For example, the tensioning mechanism of a ring wire cutting machine disclosed in utility model patent CN222372022U involves activating an electric push rod when replacing the diamond ring wire. The push rod extends and, after pressing against the machine frame column, generates a counter-force, causing the slide plate to move towards the drive sheave, thereby compressing the spring. This reduces the distance between the driven and drive sheaves, loosening the cutting wire and facilitating the removal and installation of new cutting wire. The electric push rod changes the two extreme positions of the distance between the driven and drive sheaves. If the tension needs adjustment, the distance between the movable and fixed seats in the spring seat must be changed. The position of the movable seat is manually adjusted, relying on the operator's experience. Inexperienced operators may not know the appropriate position for the movable seat. Utility Model Content

[0003] The purpose of this invention is to provide a digital tensioning mechanism for diamond cutting wire, which solves the problem of inconvenient adjustment of tension force.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The digital tensioning mechanism for diamond cutting wire includes:

[0006] The linear drive has a fixed end that is fixed to the roller support plate and a pressure sensor installed on the movable end of the linear drive.

[0007] The slide plate is slidably mounted on the spool support plate. The slide plate has a mounting part for mounting the spool and is connected to a spring baffle.

[0008] A spring seat, having a pressure-bearing surface, is used to mate with the pressure sensor;

[0009] A spring is located between the spring baffle and the spring seat.

[0010] Furthermore, the spring seat includes a fixed seat and a movable seat arranged at intervals on the left and right. The pressure-bearing surface is located on the right side of the movable seat. The fixed seat is provided with a guide rod. The movable seat is slidably assembled on the guide rod. The spring is sleeved on the guide rod and is located between the spring baffle and the movable seat.

[0011] Furthermore, the spring baffle has a through hole through which the guide rod passes.

[0012] Furthermore, the guide rod has two parallel rods, two springs, and one movable seat, which has holes for the two guide rods to pass through.

[0013] Furthermore, the linear drive is an electric actuator.

[0014] Furthermore, the pressure sensor is an S-shaped pressure sensor.

[0015] Furthermore, the spool support plate has a tensioning spool mounting hole for the tensioning spool to pass through and be mounted on the mounting part.

[0016] Furthermore, the sheave support plate also has a drive sheave mounting hole for mounting the drive sheave; the drive sheave mounting hole and the tension sheave mounting hole are spaced apart on the left and right.

[0017] Furthermore, the spool support plate is equipped with a detection sensor for detecting the extreme positions of the slide plate.

[0018] Furthermore, the detection sensor is a slotted photoelectric sensor, and the slide plate is provided with a sensing sheet that cooperates with the slotted photoelectric sensor.

[0019] The beneficial effects of this utility model are:

[0020] When adjusting the initial tension of the spring, the electric push rod extends towards the spring, driving the pressure sensor to push the movable seat in the spring seat. The movable seat moves towards the fixed seat, compressing the spring. The spring baffle is pushed by the spring, and the sliding plate moves synchronously with the spring baffle. The sliding plate drives the tensioning pulley away from the drive pulley, thus achieving the tensioning effect of the diamond cutting wire. As the electric push rod extends, the pressure sensor detects the force in real time; the greater the pressure from the pressure sensor, the greater the tension. Furthermore, the data can be transmitted to a display screen, allowing the operator to visually see the tension level of the diamond cutting wire. Additionally, digital control of the tension can be achieved. A threshold is set via a program; when the pressure sensor reaches the threshold, the electric push rod is de-energized, completing automatic tension adjustment. This digital tensioning mechanism eliminates reliance on operator experience, making adjustment more convenient and precise, thus extending the lifespan of the diamond cutting wire. Furthermore, different tension levels can be controlled during the cutting process via a program, allowing for adjustment throughout the cutting process. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0026] Embodiments of this utility model:

[0027] like Figures 1-3 As shown, the digital tensioning mechanism for diamond wire cutting includes an electric push rod, a wire pulley support plate, a sliding plate, a spring seat, and a spring. This tensioning mechanism is installed on the diamond wire cutting machine and is used to mount the drive wire pulley and the tensioning wire pulley, and can tension the tensioning wire pulley according to the control program.

[0028] The thread sheave support plate is a rectangular plate. It has mounting holes for the tensioning thread sheave and a drive thread sheave; these mounting holes are spaced apart. The diamond cutting wire is a loop, wound around the drive and tensioning thread sheaves during use. The rotation of the drive thread sheave drives the diamond cutting wire to rotate at high speed, thus achieving the cutting function.

[0029] In this embodiment, an electric linear actuator is selected as the linear drive component. The fixed end of the electric linear actuator is fixed to a roller support plate, and a pressure sensor is installed on the movable end. The pressure sensor is mounted on the movable end via a sensor mounting plate. The pressure sensor is an S-shaped pressure sensor.

[0030] The spring seat includes a fixed seat and a movable seat spaced apart on the left and right sides. The right side of the movable seat has a pressure-bearing surface for mating with a pressure sensor;

[0031] The fixed seat is equipped with a guide rod, the movable seat is slidably mounted on the guide rod, and the spring is sleeved on the guide rod.

[0032] The skateboard is mounted on a spool support plate, allowing it to slide left and right. A slider is located at the bottom of the skateboard, engaging with two rails on the spool support plate; these rails extend left and right.

[0033] The skateboard has a mounting section for installing the tensioner spool. During installation, the axle of the tensioner spool is mounted on a bearing housing, which is connected to the mounting section by bolts. The bearing housing passes through the tensioner spool mounting hole, and the tensioner spool and the skateboard are located on the front and rear sides of the spool support plate, respectively. The tensioner spool mounting hole is a rectangular hole, allowing the bearing housing a certain range of movement in the lateral direction.

[0034] A spring baffle is connected to the upper part of the skateboard; the spring is located between the spring baffle and the movable seat, keeping the spring in a compressed state. The spring baffle has a through hole through which the guide rod passes.

[0035] There are two guide rods arranged in parallel, two springs (one is shown in the figure), and one movable seat with holes for the two guide rods to pass through. The aforementioned sensor mounting plate is also guided and assembled onto the guide rods.

[0036] Operating principle of the digital tensioning mechanism for diamond wire cutting:

[0037] When adjusting the initial tension of the spring, the electric actuator extends towards the spring, driving the pressure sensor to push the movable seat in the spring seat. The movable seat moves towards the fixed seat, compressing the spring. The spring baffle is pushed by the spring, and the sliding plate moves synchronously with the spring baffle. The sliding plate then drives the tensioning pulley away from the driving pulley, thus achieving the tensioning effect of the diamond wire. As the electric actuator extends, the pressure sensor detects the force in real time; the greater the pressure from the pressure sensor, the greater the tension. The data can be transmitted to a display screen, allowing the operator to visually observe the tension of the diamond wire. Automatic tension control is also possible. A threshold is set in the program; when the pressure sensor reaches the threshold, the electric actuator is de-energized, completing the automatic tension adjustment. When replacing with new diamond wire, the spring tension needs to be released. At this time, the electric actuator is energized and retracts in the opposite direction. Finally, the sliding plate drives the tensioning pulley towards the driving pulley, slackening the diamond wire, allowing for replacement.

[0038] A detection sensor is installed on the spool support plate to detect the extreme positions of the slide plate. The detection sensor is a slotted photoelectric sensor, and the slide plate has a sensing element that works in conjunction with the slotted photoelectric sensor. Under normal circumstances, as described in the previous paragraph, the slide plate moves within its normal range and does not cause the sensing element to trigger the slotted photoelectric sensor. When the diamond wire breaks, the slide plate will move further away from the drive spool under the pushing force of the spring, or it can be understood as the slide plate exceeding its normal range of movement. At this time, the sensing element on the slide plate can trigger the slotted photoelectric sensor, thereby sending a signal, namely the diamond wire breakage alarm signal.
