Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to an easily adjustable ring-shaped wall cutting machine. Background Technology

[0002] A cutting machine is a specialized piece of equipment that uses mechanical, thermal, electrical, light, or chemical energy to divide, groove, cut, or contour materials such as metal, stone, concrete, wood, and plastic. Its core function is to separate workpieces according to preset dimensions, shapes, or trajectories using media such as cutting tools, saw blades, laser beams, plasma arcs, and water jets. It is widely used in fields such as construction, manufacturing, decoration, and rescue.

[0003] The ring wall cutting machine is a portable engineering device specifically designed for cutting operations on walls. It uses a high-speed rotating ring saw blade to move along a preset track to perform fully or semi-enclosed cutting on hard walls such as reinforced concrete, brick, and asphalt, in order to meet construction needs such as opening doorways, elevator shafts, and ventilation openings.

[0004] However, when using this ring-shaped wall cutting machine, the ring-shaped cutting saw moves parallel to the slide rail. When the cutting work in one area is completed and it needs to be moved to another area for cutting work, the machine needs to be manually lifted to the corresponding position. This position adjustment process is cumbersome, and the accuracy of manual adjustment is low. Therefore, it does not meet the current needs. In response, we have proposed a ring-shaped wall cutting machine that is easy to adjust. Utility Model Content

In this case, the machine needs to be manually lifted to the corresponding position, which is a cumbersome operation and the accuracy of manual adjustment is low.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable ring-shaped wall cutting machine, comprising a cutting movable slide rail, with a metal shell on both sides of the outer surface of the cutting movable slide rail, a stepper motor fixedly installed on the upper side inside the metal shell, the output shaft of the stepper motor connected to a transmission shaft via a coupling, a threaded rod fixedly connected to the lower end face of the transmission shaft, an internal threaded sleeve with its front and rear ends slidably connected to the metal shell being installed on the upper side of the outer surface of the threaded rod via a threaded structure, a connecting rod fixed on both sides of the lower end face of the internal threaded sleeve, a roller square adjustment turntable fixedly installed on the lower end face of the two connecting rods, and multiple electric rollers installed on the lower end face of the roller square adjustment turntable.

[0007] Preferably, a cutting sliding table is slidably installed at the middle position of the upper surface of the cutting sliding rail, and a wall cutting mechanism is fixedly installed at the middle position of the upper surface of the cutting sliding table.

[0008] Preferably, a main control module is fixedly installed inside a metal housing on one side of the stepper motor, and the stepper motor, the roller square adjustment turntable, and the electric roller are all electrically connected to the main control module;

[0009] Above the stepper motor is a safety indicator light fixedly installed on the outer surface of the metal casing. A remote control device is located on one side of the second safety indicator light from the left. The cutting moving slide, the wall cutting mechanism, and the main control module are all electrically connected to the remote control device.

[0010] Preferably, a first synchronous sprocket is fixedly sleeved on both sides of the outer surface of the transmission shaft, and a second synchronous sprocket is provided on one side of each of the two first synchronous sprockets, and the first synchronous sprockets and the second synchronous sprockets with corresponding positions are connected in series by a synchronous chain.

[0011] Preferably, the second synchronous sprocket is connected to a square rotating shaft at its shaft center. The outer side of the bottom end of the square rotating shaft is provided with a threaded abutment located inside the metal housing and connected to the metal housing by a threaded structure. A square slot is provided at the middle position of the upper end face of the threaded abutment, and the square rotating shaft is inserted into the inside of the square slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a cutting sliding rail for moving the wall cutting mechanism, with a metal shell fixed to both the front and rear ends. The metal shell contains electric rollers that can be driven up and down by a stepper motor. When the equipment needs to perform cutting operations in multiple areas of a wall, the overall movement trajectory of the equipment is input to the central control module, which controls the stepper motor and electric rollers, via a remote control device. After the equipment completes the cutting operation at a certain point, the central control module will first push the electric rollers down through the stepper motor to lift the entire equipment. After the entire equipment is lifted, the electric rollers will move the entire equipment to the next cutting area. This technical solution enables the equipment to automatically adjust its cutting work area, improving the automation level of the equipment while ensuring the accuracy of the cutting operation.

[0016] 2. This utility model uses a stepper motor to drive the electric roller to move downwards, while simultaneously driving two threaded abutments whose lower end faces are in contact with the electric roller to move downwards. The threaded abutments whose lower end faces are in contact with the upper end faces of the electric rollers prevent the cutting slide rail, cutting slide table, and wall cutting mechanism from moving downwards on their own during the movement of the equipment by the electric rollers, thereby improving the overall stability of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The cutting sliding rail 1 (model HGR15), stepper motor 6 (model DM542), and wall cutting mechanism 3 (model jy1200) mentioned in this utility model can be obtained from the market or through private customization.

[0024] Please see Figures 1 to 4 This utility model provides an embodiment of an easily adjustable ring-shaped wall cutting machine, including a cutting movable slide rail 1. A metal housing 16 is provided on both sides of the outer surface of the cutting movable slide rail 1. A stepper motor 6 is fixedly installed on the upper side inside the metal housing 16. The output shaft of the stepper motor 6 is connected to a transmission shaft 8 via a coupling. A threaded rod 7 is fixedly connected to the lower end face of the transmission shaft 8. An internal threaded sleeve 9, whose front and rear end faces are slidably connected to the metal housing 16, is installed on the upper side of the outer surface of the threaded rod 7 via a threaded structure. The lower end face of the internal threaded sleeve 9 is fixed on both sides. A connecting rod 10 is provided, and a square adjusting turntable 11 with rollers is fixedly installed on the lower end face of the two connecting rods 10. Multiple electric rollers 12 are installed on the lower end face of the square adjusting turntable 11. A cutting moving slide 2 is slidably installed at the middle position of the upper end face of the cutting moving slide 1. A wall cutting mechanism 3 is fixedly installed at the middle position of the upper end face of the cutting moving slide 2. A main control module 20 is fixedly installed inside the metal shell 16 on one side of the stepper motor 6, and the stepper motor 6, the square adjusting turntable 11 with rollers and the electric rollers 12 are all electrically connected to the main control module 20.

[0025] Above the stepper motor 6 is a safety indicator light 5 fixedly installed on the outer surface of the metal housing 16. A remote control device 4 is located on one side of the second safety indicator light 5 from the left. The cutting slide 2, the wall cutting mechanism 3, and the main control module 20 are all electrically connected to the remote control device 4. The cutting slide 2, the wall cutting mechanism 3, and the main control module 20 can be controlled through the remote control device 4.

[0026] When it is necessary to use the equipment for cutting operations, the wall cutting mechanism 3 is started by the remote control device 4, and then the wall cutting mechanism 3 is driven by the cutting movable slide table 2 to move along the specified cutting path to carry out the cutting operation.

[0027] When the equipment needs to be used to cut multiple areas of a wall, during the first cutting operation, the overall movement trajectory of the equipment is input to the main control module 20, which controls the stepper motor 6 and the electric roller 12, through the remote control device 4. After the equipment completes the cutting operation at a certain point, the main control module 20 will first start the stepper motor 6. The stepper motor 6 can drive the threaded rod 7 connected to it through the transmission shaft 8 to rotate. Since the front and rear ends of the inner threaded sleeve 9, which is installed on the outer surface of the threaded rod 7 through the threaded structure, are slidably connected to the inner wall of the metal shell 16, the inner threaded sleeve 9 cannot rotate on its own.

[0028] When the threaded rod 7 rotates, the internal threaded sleeve 9, which is threadedly connected to it but cannot rotate on its own, will move up and down under the drive of the threaded structure. At this time, the internal threaded sleeve 9 moves downward. During the downward movement of the internal threaded sleeve 9, the roller square adjustment turntable 11 connected to it through the connecting rod 10 and the electric roller 12 installed on the lower end face of the roller square adjustment turntable 11 will move downward together. When the lower end face of the electric roller 12 contacts the wall and the electric roller 12 is still being driven downward, the entire equipment will be lifted. After the entire equipment is lifted, the electric roller 12 will move the entire equipment to the next cutting area.

[0029] After the equipment is moved to the next cutting area, the electric roller 12 is driven to move upward until the lower end of the cutting slide rail 1 is in contact with the wall again. Then the cutting operation can be carried out by the cutting slide 2 and the wall cutting mechanism 3.

[0030] The above technical solutions enable the equipment to automatically adjust its cutting work area, which improves the automation level of the equipment while ensuring the accuracy of the cutting operation.

[0031] When the stepper motor 6 is started by the main control module 20 and drives the electric roller 12 downward, the safety indicator 5 located above the stepper motor 6 will automatically brighten and sound an alarm to remind the device to start moving and not to approach the device.

[0032] The above technical solution can prevent workers from getting too close to moving equipment, which could cause the equipment to collide with the workers and cause injury, or cause the equipment's movement trajectory to change.

[0033] A first synchronous sprocket 17 is fixedly sleeved on both sides of the outer surface of the transmission shaft 8. A second synchronous sprocket 18 is provided on one side of each of the two first synchronous sprockets 17, and the corresponding first synchronous sprockets 17 and second synchronous sprockets 18 are connected in series by a synchronous chain 14. A square shaft 13 is connected to the axis of the second synchronous sprocket 18. A threaded abutment 15 is provided on the outer side of the bottom end of the square shaft 13, located inside the metal housing 16 and connected to the metal housing 16 by a threaded structure. A square slot 19 is provided in the middle of the upper end face of the threaded abutment 15, and the square shaft 13 is inserted into the square slot 19. The inner wall of the square slot 19 has a square cross-section. The outer surface of the square shaft 13 fits against the inner wall of the square slot 19, and the square shaft 13 and the square slot 19 are slidably connected. The first synchronous sprockets 17 fixedly sleeved on the outer surface of the transmission shaft 8 during rotation are... The first synchronous sprocket 17 will rotate together with the second synchronous sprocket 18 connected in series with it via the synchronous chain 14 and the square rotating shaft 13 connected to the axis of the second synchronous sprocket 18. Since the outer surface of the square rotating shaft 13 is in contact with the inner wall of the square slot 19 located on the upper end face of the threaded abutment 15, when the square rotating shaft 13 rotates, the threaded abutment 15 will rotate synchronously. Driven by the threaded structure, the rotating threaded abutment 15 will move up and down. When the electric roller 12 moves downward, the threaded abutment 15 will move downward at the same speed. The threaded abutment 15, whose lower end face is in contact with the upper end face of the electric roller 12, can prevent the cutting moving slide rail 1, the cutting moving slide table 2 and the wall cutting mechanism 3 from moving downward on their own during the process of moving the equipment via the electric roller 12, thereby improving the overall stability of the equipment.

[0034] A stop plate is mounted on the lower end face of the threaded stop rod 15 via a roller bearing, and the lower end face of the stop plate is in contact with the upper end face of the electric roller 12. The stop plate located on the lower end face of the threaded stop rod 15 reduces the friction between the two, thereby preventing the threaded stop rod 15 from jamming the electric roller 12 and causing the electric roller 12 to be unable to be adjusted in orientation by the roller square adjustment turntable 11.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
