Description

Technical Field

[0001] This utility model relates to the field of power equipment stress monitoring technology, and in particular to a power equipment foundation stress monitoring device. Background Technology

[0002] During the cutting process, the cutting tool is subjected to a reaction force from the workpiece being cut. The magnitude and direction of this reaction force are affected by factors such as the direction of the blade, the cutting angle, and the cutting direction, which ultimately affect the cutting effect. In addition, inappropriate reaction force can also affect the service life of the tool.

[0003] A patent with publication number CN221020158U discloses "a sensor for monitoring the force on a cutting tool, including a mounting box disposed on both sides of the cutting head and a pressure sensing plate installed inside the mounting box; a force-transmitting bead for the sensing plate, the force-transmitting bead for the sensing plate being installed on the side of the mounting box facing the cutting head, and the force-transmitting bead for the sensing plate being tangent to both the pressure sensing plate and the surface of the cutting head; an adjustment mechanism, the adjustment mechanism being used to connect the mounting box to the tool handle fixed to the end of the cutting head and to adjust the position of the pressure sensing plate on both sides of the cutting head... A detachable ring is fitted over the fixed ring, and the second screw hole is aligned with the first screw hole at different positions according to the different cutting depths of the cutting head, and then the screw passes through the second screw hole and the first screw hole simultaneously for limiting." However, the adjustment mechanism is rather cumbersome in actual operation, and due to the limitation on the number of first screw holes (e.g., eight sets), the selectivity and flexibility of the adjustment position are greatly limited, and only fixed adjustments corresponding to preset hole positions can be achieved. Utility Model Content

[0004] The purpose of this utility model is to provide a power equipment foundation stress monitoring device in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power equipment foundation stress monitoring device includes a cutter head and a cutter handle fixed to the other end of the cutter head. A fixed ring is fixedly sleeved on one end of the cutter handle near the cutter head. A sleeve sleeved on the outside of the fixed ring is slidably connected to the outside of the cutter head. A movable ring is movably sleeved on the outside of the cutter handle. The movable ring is fixedly connected to one end of the sleeve. The movable ring and the fixed ring are connected by an adjusting screw. An installation groove is opened at the other end of the sleeve. A force-transmitting bead of a sensing element is rotatably embedded in the side of the installation groove near the cutter head. A pressure sensing element is disposed in the installation groove. A pressure plate abutting against the pressure sensing element is fixedly connected to the installation groove by a first bolt. The force-transmitting bead of the sensing element is tangent to the surfaces of both the cutter head and the pressure sensing element.

[0007] As a further description of the above technical solution:

[0008] Guide blocks are fixedly connected to the inner walls on both sides of the sleeve, and guide grooves that cooperate with the guide blocks are opened on both sides of the fixing ring.

[0009] As a further description of the above technical solution:

[0010] The sleeve has mounting grooves at both ends that mate with the cutter head and the retaining ring, respectively. A felt layer that contacts the cutter head is bonded to the mounting groove that mates with the cutter head.

[0011] As a further description of the above technical solution:

[0012] The sleeve has a weight-reducing groove located between the cutter head and the cutter handle.

[0013] As a further description of the above technical solution:

[0014] The movable ring and the sleeve are connected by a series of second bolts threaded together.

[0015] As a further description of the above technical solution:

[0016] A limiting plate is fixedly connected to one end of the adjusting screw near the cutter head.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by rotating the adjusting screw, the movable ring is driven to move the sleeve axially, thereby adjusting the contact position between the sensing element force transmission bead and the cutter head. When the cutting depth of the cutter head is shallow, the sensing element force transmission bead is adjusted to be closer to the tip of the cutter head to better monitor the force. Conversely, the sensing element force transmission bead is adjusted to be farther away from the tip of the cutter head to avoid the presence of the sleeve from hindering the cutting action. The stepless adjustment of the position through the threaded transmission improves the selectivity and flexibility of the adjustment position.

[0019] 2. In this utility model, when the blade is subjected to force and tends to deform during cutting, the force will be transmitted to the pressure sensor through the force transmission bead of the sensing plate. The pressure sensor senses the magnitude and direction of the applied force and transmits the sensed data information to the sensor control system through the wireless transmission module installed at the bottom for data analysis, thereby determining whether there are deviations in the current cutting angle, blade direction, cutting direction, etc., improving cutting accuracy while reducing blade damage.

[0020] 3. In this utility model, the two ends of the sleeve have assembly grooves that cooperate with the cutter head and the fixing ring, respectively. The assembly groove that cooperates with the cutter head is bonded with a felt layer that contacts the cutter head, which prevents the waste generated when the cutter head is cutting from entering between the induction plate force transmission bead and the cutter head, thereby improving the force transmission sensitivity of the induction plate force transmission bead.

[0026] 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 without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-3This utility model provides a technical solution: a power equipment foundation stress monitoring device, including a cutter head 1 and a cutter handle 2 fixed to the other end of the cutter head 1. The cutter handle 2 is installed on the cutting equipment, and its installation principle is based on existing installation methods, which will not be described in detail here. A fixing ring 10 is fixedly sleeved on one end of the cutter handle 2 near the cutter head 1. A sleeve 3 is slidably connected to the outside of the fixing ring 10 and sleeved on the outside of the cutter head 1. Guide blocks 13 are fixedly connected to the inner walls on both sides of the sleeve 3. Guide grooves 1001 that cooperate with the guide blocks 13 are opened on both sides of the fixing ring 10. A movable ring 7 is movably sleeved on the outside of the cutter handle 2. The sleeve 3 is connected to the blade head 1 by several second bolts 14 threaded together. The movable ring 7 and the fixed ring 10 are connected by an adjusting screw 9. The end of the adjusting screw 9 near the blade head 1 is fixedly connected to a limit plate 8. The other end of the sleeve 3 is provided with a mounting groove 302. The mounting groove 302 near the blade head 1 is rotatably embedded with a sensing element force transmission bead 12. A pressure sensing element 11 is provided in the mounting groove 302. A pressure plate 4 that abuts against the pressure sensing element 11 is fixedly connected to the mounting groove 302 by a first bolt 5. The sensing element force transmission bead 12 is tangent to both the blade head 1 and the surface of the pressure sensing element 11. First, when the cutter head 1 is subjected to force and tends to deform during cutting, the force is transmitted to the pressure sensor 4 via the force transmission bead 5. The pressure sensor 4 senses the magnitude and direction of the applied force and transmits the sensed data to the sensor control system via the wireless transmission module installed at the bottom for data analysis. This allows the system to determine whether there are any deviations in the current cutting angle, blade direction, and cutting direction, thereby improving cutting accuracy and reducing tool damage. Second, by rotating the adjusting screw 9, the movable ring 7 is driven to move the sleeve 3 axially according to the thread transmission principle. This adjusts the contact position between the force transmission bead 12 and the cutter head 1. When the cutting depth of the cutter head 1 is shallow, the force transmission bead 12 is adjusted to be closer to the tip of the cutter head 1 to better monitor the force. Conversely, the force transmission bead 12 is adjusted to be further away from the tip of the cutter head 1 to avoid the sleeve 3 obstructing the cutting action. This stepless adjustment method using thread transmission improves the selectivity and flexibility of the adjustment position.

[0028] It should be noted that a remote transmission module electrically connected to the pressure sensing element 4 is installed at the bottom of the mounting slot 302 to transmit data with the external sensor control system. Since this type of data transmission mode of the sensor is existing technology, it will not be described in detail here.

[0029] Specifically, such as Figure 1-3 As shown, the sleeve 3 has mounting grooves at both ends that mate with the cutter head 1 and the fixing ring 10, respectively. A felt layer 6 that contacts the cutter head 1 is bonded to the mounting groove that mates with the cutter head 1, which prevents the waste generated by the cutter head 1 during cutting from entering between the induction plate force transmission bead 12 and the cutter head 1, thereby improving the force transmission sensitivity of the induction plate force transmission bead 12.

[0030] Specifically, such as Figure 2 As shown, the sleeve 3 has a weight-reducing groove 301 located between the cutter head 1 and the cutter shank 2, which reduces the overall weight and makes it easier for the cutter head 1 to cut the workpiece.

[0031] Working principle: When in use, firstly, when the cutter head 1 is subjected to force and tends to deform during cutting, the force will be transmitted to the pressure sensor 4 through the force transmission bead 5. The pressure sensor 4 senses the magnitude and direction of the applied force and transmits the sensed data information to the sensor control system through the wireless transmission module installed at the bottom for data analysis, thereby determining whether there are any deviations in the current cutting angle, blade direction, cutting direction, etc., improving cutting accuracy while reducing tool damage;

[0032] Secondly, by rotating the adjusting screw 9, according to the principle of thread transmission, the moving ring 7 drives the sleeve 3 to move axially, thereby adjusting the contact position between the sensing element force transmission bead 12 and the cutter head 1. When the cutting depth of the cutter head 1 is shallow, the sensing element force transmission bead 12 is adjusted to be closer to the tip of the cutter head 1 to better monitor the force. Conversely, the sensing element force transmission bead 12 is adjusted to be farther away from the tip of the cutter head 1 to avoid the presence of the sleeve 3 from hindering the cutting action. Through this stepless adjustment method of thread transmission, the selectivity and flexibility of the adjustment position are improved.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
