Description

Technical Field

[0001] This application relates to the technical field of grooving equipment, and in particular to a grooving device. Background Technology

[0002] During the construction of a house, it is necessary to cut grooves in the walls to lay water and electricity pipes. Workers usually use a grooving machine to cut grooves in the walls.

[0003] Existing grooving machines are usually handheld. Construction workers first mark the location where grooving is needed on the wall, and then hold the grooving machine in their hands so that the toothed cutter on the grooving machine cuts and grooves along the marked location.

[0004] Regarding the aforementioned technologies, existing grooving machines typically require manual operation by construction workers. During operation, workers are prone to hand tremors, which may lead to inconsistent groove depths in the walls, affecting the subsequent laying of water and electricity pipes. Summary of the Invention

[0005] To address the issue of the high operational difficulty of grooving machines, which affects the grooving effect, this application provides a grooving device.

[0006] The grooving device provided in this application adopts the following technical solution:

[0007] A grooving device includes a movable frame with casters at its bottom, a horizontal screw mounted on the frame, a motor mounted on the frame, the output shaft of the motor fixedly connected to the end of the horizontal screw, a mounting bracket sleeved around the horizontal screw, the mounting bracket threadedly engaging with the horizontal screw, a vertical screw and a vertical guide rod rotatably mounted on the mounting bracket, a second motor mounted on the mounting bracket, the output shaft of the second motor fixedly connected to the end of the vertical screw, a mounting seat sleeved around the outer periphery of the vertical screw and the outer periphery of the vertical guide rod, the mounting seat threadedly engaging with the vertical screw, a grooving machine mounted on the mounting seat, and an adjustment component for adjusting the position of the grooving machine provided on the mounting seat.

[0008] By adopting the above technical solution, the mobile frame is moved to the location where the wall needs to be grooved, and then the position of the grooving machine is adjusted using the adjustment components. Motor 1 or Motor 2 is started, causing the horizontal or vertical screw to rotate, thereby driving the grooving machine to move horizontally or vertically. The grooving machine remains stable during the movement, ensuring consistent grooving depth and reducing the workload of construction personnel, thus saving manpower.

[0009] Preferably, the mounting base includes a movable plate, the adjustment assembly includes a support plate mounted on the top surface of the movable plate, a rotating rod is rotatably mounted on the support plate, two mutually perpendicular rotating plates are fixed to the outer periphery of the rotating rod, the grooving machine is fixedly connected to the relative inner sides of the two rotating plates, and the rotation axis of the grooving machine's toothed cutter is parallel to the horizontal screw.

[0010] By adopting the above technical solution, rotating the rotating rod causes the two rotating plates to move, which in turn drives the grooving machine to rotate, thereby changing the direction of the grooving machine's toothed cutter, and thus grooving the wall according to the requirements.

[0011] Preferably, the top surface of the bearing plate is fixed with two fixing blocks. The fixing blocks have a limiting groove on their side near the rotating plate. The fixing blocks slide along their width direction through the limiting groove to install the limiting blocks. The side of the rotating plate has a connecting groove for inserting the limiting blocks. The side of the limiting blocks away from the rotating plate is fixed with a limiting spring. The end of the limiting spring away from the limiting blocks is fixedly connected to the inner wall of the limiting groove.

[0012] By adopting the above technical solution, when the grooving machine is moved horizontally or vertically, the side of one of the rotating plates is in contact with the top surface of the bearing plate, and the limiting block is inserted into the connecting groove under the elastic force of the limiting spring, thereby limiting the rotating plate and fixing the position of the grooving machine.

[0013] Preferably, the side of the fixing block is provided with a pushing groove that communicates with the limiting groove. The fixing block slides along its own length direction to install the pushing block through the pushing groove. The side of the limiting block is provided with a limiting through groove for the pushing block to pass through. The limiting through groove is provided with a first inclined surface near the inner wall of the limiting spring. The side of the pushing block near the limiting block is provided with a second inclined surface for abutting against the first inclined surface.

[0014] By adopting the above technical solution, the pushing block is moved toward the direction of the limiting block. The pushing block abuts against the inclined surface one and the inclined surface two, thereby pushing the limiting block to move away from the rotating plate, so that the limiting block is disengaged from the connecting groove, so that the construction personnel can adjust the position of the grooving machine.

[0015] Preferably, a reset block is fixed to the side of the pushing block, and a reset groove is formed on the inner wall of the pushing groove. The reset block is slidably connected to the fixed block along the length direction of the fixed block through the reset groove. A reset spring is fixed to the side of the reset block near the limiting block, and the end of the reset spring away from the reset block is fixedly connected to the inner wall of the reset groove.

[0016] By adopting the above technical solution, after the push block is released, the push block moves away from the limit block under the elastic force of the reset spring, so that the push block is reset, so that the limit block can be reset under the action of the limit spring.

[0017] Preferably, the top surface of the movable plate is provided with a sliding groove, and the bottom surface of the bearing plate is fixed with a slider. The slider is slidably connected to the movable plate along the length direction of the fixed block through the sliding groove. An adjusting screw is rotatably installed in the sliding groove, and the adjusting screw is threadedly engaged with the slider.

[0018] By adopting the above technical solution, rotating the adjusting screw causes the slider to move, thereby adjusting the distance between the grooving machine and the wall, and thus adjusting the grooving depth.

[0019] Preferably, a positioning gear is fixedly sleeved on the outer periphery of the adjusting screw, a positioning groove is provided on the top surface of the moving plate, a positioning block is installed on the moving plate by sliding vertically through the positioning groove, the bottom end of the positioning block is provided with a pointed tip, and the positioning block can be inserted into the tooth groove of the positioning gear.

[0020] By adopting the above technical solution, after the grooving machine is moved to the corresponding position, the positioning block is moved downward and inserted into the tooth groove of the positioning gear, thereby limiting the adjustment screw and making it difficult for the adjustment screw to rotate, thus ensuring consistent grooving depth.

[0021] Preferably, a pressing block is fixed to the side of the positioning block, a pressing groove is formed on the inner wall of the positioning groove, the pressing block is slidably connected to the moving plate through the inner edge of the pressing groove, a pressing spring is fixed to the top surface of the pressing block, and the bottom end of the pressing spring is fixedly connected to the inner top surface of the pressing groove.

[0022] By adopting the above technical solution, the positioning block moves downward under the elastic force of the compression spring and is inserted into the tooth groove of the positioning gear, thereby limiting the adjustment screw.

[0023] Preferably, the movable plate has a mounting groove on its side near the wall. A mounting block is slidably mounted on the movable plate along the length of the adjusting screw via the mounting groove. A movable contact is fixed to the side of the mounting block. A fixed contact, electrically contacting the movable contact, is fixed to the inner wall of the mounting groove. The fixed contact is electrically connected to a power source. The movable frame is equipped with a switch one electrically connected to motor one and a switch two electrically connected to motor two. The movable contact is electrically connected to both switch one and switch two. A stop block is fixed to the side of the mounting block. A stop groove is formed on the inner wall of the mounting groove. The stop block is slidably connected to the movable plate along the length of the adjusting screw via the stop groove. A stop spring is fixed to the side of the stop block away from the wall. The end of the stop spring away from the stop block is fixedly connected to the inner wall of the stop groove.

[0024] By adopting the above technical solution, after adjusting the position of the grooving machine, start the grooving machine and move the moving frame towards the wall so that the moving plate is in contact with the wall. At this time, the mounting block moves into the mounting groove, and the moving contact and the fixed contact make electrical contact, so that both switch one and switch two are electrically connected to the power supply. By controlling switch one or switch two, the power to motor one or motor two is turned on and off, thereby controlling the horizontal screw or vertical screw. After grooving is completed, move the moving frame away from the wall. Under the elastic force of the abutment spring, the mounting block moves away from the moving plate, the moving contact and the fixed contact separate, motor one and motor two are de-energized, and the grooving machine stops moving.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Move the mobile frame to the location where the wall needs to be grooved, then use the adjustment components to adjust the position of the grooving machine, start motor one or motor two to make the horizontal or vertical screw rotate, thereby driving the grooving machine to move horizontally or vertically. The grooving machine remains stable during the movement, ensuring consistent grooving depth and reducing the workload of construction workers, thus saving manpower.

[0027] 2. Move the pushing block toward the direction of the limiting block. The pushing block abuts against the inclined plane one and the inclined plane two, thereby pushing the limiting block away from the rotating plate, so that the limiting block disengages from the connecting groove, so that the construction personnel can adjust the position of the grooving machine.

[0028] 3. After adjusting the position of the grooving machine, start the grooving machine and simultaneously move the moving frame towards the wall so that the moving plate is in contact with the wall. At this time, the mounting block moves into the mounting slot, and the moving contact and the fixed contact make electrical contact, so that both switch one and switch two are electrically connected to the power supply. By controlling switch one or switch two, the power to motor one or motor two is turned on and off, thereby controlling the horizontal screw or vertical screw. After grooving is completed, move the moving frame away from the wall. Under the elastic force of the abutment spring, the mounting block moves away from the moving plate, the moving contact and the fixed contact separate, motor one and motor two are de-energized, and the grooving machine stops moving.

An adjusting screw 33 is rotatably mounted within the groove 32, and the slider 51 is threadedly engaged with the adjusting screw 33.

[0040] Rotating the adjusting screw 33 causes the slider 51 to move, thereby adjusting the distance between the grooving machine 55 and the wall, thus adjusting the grooving depth. Starting motor 16 causes the horizontal screw 15 to rotate, which in turn causes the mounting bracket 2 to move horizontally, allowing the grooving machine 55 to groove the wall horizontally. Starting motor 26 causes the vertical screw 25 to rotate, which in turn causes the mounting base 3 to move vertically, allowing the grooving machine 55 to groove the wall vertically.

[0041] Reference Figure 2 and Figure 3 A cavity 341 is provided inside the movable plate 31, and a positioning gear 34 is rotatably installed inside the cavity 341. The positioning gear 34 is sleeved and fixed to the outer peripheral surface of the adjusting screw 33. A positioning groove 35 communicating with the cavity 341 is opened on the top surface of the movable plate 31, and a positioning block 36 is installed on the movable plate 31 by sliding vertically through the positioning groove 35.

[0042] Pull the positioning block 36 upward to separate it from the positioning gear 34, so that the construction personnel can adjust the position of the grooving machine 55. After the adjustment is completed, release the positioning block 36. Under the elastic force of the compression spring 39, the positioning block 36 moves downward and is inserted into the tooth groove of the positioning gear 34, so that the bearing plate 5 is not easy to move.

[0043] Reference Figure 1 and Figure 2 A mounting groove 41 is provided on the side of the movable plate 31 near the wall. The movable plate 31 slides along its width direction through the mounting groove 41 to mount the mounting block 4. Abutment blocks 42 are fixed to both sides of the mounting block 4. An abutment groove 43 is provided on the inner wall of the mounting groove 41. The abutment blocks 42 slide along the width direction of the movable plate 31 through the abutment groove 43. An abutment spring 44 is fixed to the side of the abutment block 42 away from the wall. The end of the abutment spring 44 away from the abutment block 42 is fixedly connected to the inner wall of the abutment groove 43. A movable contact piece 45 is fixed to the side of the mounting block 4 away from the wall. A fixed contact piece 46, which can make electrical contact with the movable contact piece 45, is fixed to the inner wall of the mounting groove 41 away from the wall.

The movable frame 1 is equipped with a switch 47 electrically connected to motor 16 and a switch 48 electrically connected to motor 26. The movable contact 45 is electrically connected to switch 47 and switch 48.

[0044] Move the movable frame 1 towards the wall and start the grooving machine 55. The grooving machine 55 cuts the wall. When the movable plate 31 abuts against the wall, the mounting block 4 is fully inserted into the mounting groove 41. The moving contact 45 and the fixed contact 46 make electrical contact. Switch 1 47 and switch 2 48 are both connected to the power supply. At this time, start switch 1 47 or switch 2 48. Motor 1 16 or motor 2 26 is powered on and works, so that the grooving machine 55 moves in the horizontal or vertical direction and grooves the wall. After the grooving machine 55 moves to the designated position, move the movable frame 1 away from the wall. The mounting block 4 moves towards the wall under the elastic force of the abutment spring 44. The moving contact 45 separates from the fixed contact 46. Motor 1 16 and motor 2 26 are both de-energized, and the grooving machine 55 stops moving.

[0045] Reference Figure 4 and Figure 5 A rotating rod 52 is rotatably mounted on the top surface of the bearing plate 5. Two mutually perpendicular rotating plates 53 are fixed to the outer circumference of the rotating rod 52. A grooving machine 55 is located between the two rotating plates 53 and is fixedly connected to the inner sides of the two rotating plates 53. The rotating shaft of the grooving machine 55 is perpendicular to one of the rotating plates 53. Two fixing blocks 56 are fixed to the top surface of the bearing plate 5, located on both sides of the rotating rod 52. The fixing blocks 56 correspond one-to-one with the rotating plates 53 and can be engaged with the corresponding rotating plates 53. A limiting groove 61 is formed on the side of the fixing block 56 near the rotating plate 53. The fixing block 56 slides along the length of the moving plate 31 through the limiting groove 61 to install the limiting block 6. A connecting groove 54 for inserting the limiting block 6 is formed on the side of the rotating plate 53 away from the rotating rod 52. A limiting spring 62 is fixed to the side of the limiting block 6 away from the rotating plate 53. The end of the limiting spring 62 away from the limiting block 6 is fixedly connected to the inner wall of the limiting groove 61 away from the rotating plate 53. An inclined surface 3 65 is provided on the top surface of the limiting block 6, and the inclined surface 3 65 is located on the side of the limiting block 6 closer to the rotating plate 53.

[0046] When the toothed cutter of the grooving machine 55 is moved vertically or horizontally, one rotating plate 53 is in a vertical state, and the bottom surface of the other rotating plate 53 is in contact with the top surface of the bearing plate 5. Under the action of the limiting spring 62, the limiting block 6 moves toward the rotating plate 53, so that the limiting block 6 is inserted into the connecting groove 54 of the adjacent rotating plate 53, thereby limiting and fixing the grooving machine 55, so that the grooving machine 55 can work stably.

[0047] Reference Figure 4 and Figure 5The fixed block 56 has a pushing groove 71 on its side away from the wall, which communicates with the limiting groove 61. The fixed block 56 slides along its length to mount the pushing block 7 through the pushing groove 71. The limiting block 6 has a limiting through groove 63 on its side for the pushing block 7 to pass through. The limiting through groove 63 has a first inclined surface 64 near the inner wall of the limiting spring 62. The pushing block 7 has a second inclined surface 72 near the side of the limiting block 6 for abutting against the first inclined surface 64. Reset blocks 74 are fixed on both sides of the pushing block 7. The inner wall of the pushing groove 71 has a reset groove 73. The reset blocks 74 slide along the width of the moving plate 31 and are connected to the fixed block 56 through the reset groove 73. A reset spring 75 is fixed on the side of the reset block 74 near the limiting block 6. The end of the reset spring 75 away from the reset block 74 is fixedly connected to the inner wall of the reset groove 73.

[0048] The push block 7 is moved toward the direction of the limit block 6. The push block 7 abuts against the inclined surface 64 and the inclined surface 72, thereby pushing the limit block 6 toward the direction away from the rotating plate 53, so that the limit block 6 is disengaged from the connecting groove 54, so that the construction personnel can adjust the direction of the tooth cutter of the grooving machine 55.

[0049] The implementation principle of the grooving device in this application embodiment is as follows: the movable frame 1 is moved toward the wall, the grooving machine 55 is started, the grooving machine 55 cuts the wall, when the movable plate 31 is in contact with the wall, the moving contact 45 and the fixed contact 46 make electrical contact, the switch 1 47 or the switch 2 48 is turned on, so that the horizontal screw 15 or the vertical screw 25 rotates, and the grooving machine 55 performs grooving along the horizontal or vertical direction, which has high working efficiency and good construction quality.
