Therefore, the three groups of planer tools are in a vertical state.

Description

Technical Field

[0001] This utility model relates to the field of grooving machine technology, and more specifically, to a vertical three-line grooving machine. Background Technology

[0002] The vertical grooving machine is a CNC machine specifically designed for precision grooving of metal sheets. Its vertical structure design optimizes processing accuracy and ease of operation, and it is widely used in stainless steel processing, building decoration and other fields. It mainly achieves grooving of the sheet by driving the cutter head to move back and forth.

[0003] Existing vertical grooving machines can only perform horizontal grooving on boards because the direction of the planer blade is fixed and the machine moves the blade horizontally. If vertical grooving is required, the board needs to be adjusted, which is very cumbersome and not conducive to quickly achieving both horizontal and vertical grooving. Therefore, we propose a vertical three-line grooving machine. Utility Model Content

[0009] Preferably, the first L-shaped plate frame has a T-shaped strip arranged on the side facing the rack, and the rack has a T-shaped groove, which fits onto the T-shaped strip.

[0010] Preferably, rectangular strips are arranged on both sides of the bottom of the workbench, and an installation strip is arranged in the center of the bottom of the workbench.

A lead screw is rotatably arranged inside the rectangular groove, and the lead screw passes through the installation strip. A motor is arranged on the front side of the machine body, and the rotation shaft of the motor output end is connected to the lead screw.

[0011] Preferably, a stabilizing component is arranged on the front side of the top of the horizontal part of the L-shaped mounting plate. The stabilizing component includes a second L-shaped plate frame, which is arranged on the L-shaped mounting plate. A third electro-hydraulic push rod corresponding to the gear is arranged on the top of the second L-shaped plate frame. A block is arranged on the piston end of the third electro-hydraulic push rod.

The cleaning block is close to the first L-shaped plate frame, and the side of the cleaning block facing away from the first L-shaped plate frame is an inclined scraping edge.

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

[0015] 1. This utility model, through its designed tool holder, gears, drive plate, and first electro-hydraulic push rod, allows the planer blades to initially be horizontal when grooving the board. Then, the sliding frame, in conjunction with the fixed plate, lowers and moves the three-line cutter head structure horizontally. At this point, the three sets of planers on the three-line cutter head structure can complete the transverse three-line grooving of the board. When longitudinal grooving is required, the first electro-hydraulic push rod directly moves the drive plate, which then rotates the gear 90 degrees. This causes the tool holder and its planers to rotate 90 degrees, bringing the three sets of planers vertical. The worktable then moves the board back and forth, completing the longitudinal three-line grooving of the board. This allows for rapid transverse and longitudinal grooving of the board, solving the technical problem that current vertical grooving machines are not suitable for rapid transverse and longitudinal grooving. Therefore, this utility model has the advantage of rapidly performing transverse and longitudinal grooving on boards.

[0016] 2. The drive plate of this utility model is formed by combining a first L-shaped plate frame and three sets of racks. All three sets of racks are slidably arranged on the first L-shaped plate frame. Therefore, when adjusting the direction of the planer blades, the operator can use the second electric hydraulic push rod on the first L-shaped plate frame to drive the corresponding racks to move up and down, thereby adjusting the meshing state between the racks and the corresponding gears. This allows for free adjustment of the rotation of the three sets of planer blades as needed. When it is necessary to perform single-line or double-line grooving on the edge of the board, one or two sets of racks and gears can be directly controlled to mesh, thus controlling the direction of one or two sets of planer blades. The edges of the board are planed with corresponding unidirectional or double-line grooving, which can better meet the need for rapid horizontal and vertical grooving of the board. Moreover, the three sets of racks and the first L-shaped board frame work together so that when the three sets of planer blades are adjusted, the three sets of racks mesh with the three sets of gears at the same time. Then, the first L-shaped board frame can drive the three sets of racks to synchronously drive the three sets of gears, so as to achieve simultaneous adjustment of the direction of the three sets of planer blades. This makes the direction adjustment of the three sets of planer blades coordinated. Similarly, the direction adjustment of the two sets of planer blades is also coordinated, without the need for additional adjustment, ensuring the accuracy of the direction adjustment of the three sets of planer blades or the two sets of planer blades.

[0017] 3. A stabilizing component is arranged on the horizontal part of the fixed plate of this utility model, and a square hole is opened at the center of the top of the gear. When the drive plate drives the gear to rotate to achieve horizontal and vertical adjustment of the planer, the operator can directly drive the corresponding block to descend through the third electric hydraulic push rod in the stabilizing component, so that the block is inserted into the square hole of the corresponding gear, thereby achieving stable positioning of the gear. At this time, the upper part of the block is located inside the square tube, and the square tube can limit the block in the horizontal direction, further ensuring the positioning stability of the block on the gear, that is, ensuring the stability of the planer after horizontal and vertical adjustment, thereby further ensuring the effect of the planer to quickly plan the plate horizontally and vertically.

[0018] 4. This utility model arranges several sets of rollers at the bottom of the first L-shaped plate frame, and then arranges cleaning structures on both sides of the first L-shaped plate frame. Therefore, with the cooperation of the rollers, the first L-shaped plate frame generates rolling friction with the rectangular limiting groove, reducing friction. While limiting the first L-shaped plate frame, it can ensure that the first L-shaped plate frame moves more smoothly in the rectangular limiting groove. Moreover, when the first L-shaped plate frame moves, the cleaning block in its corresponding side structure will be pushed against the bottom of the rectangular limiting groove by the push spring. The inclined scraper edge of the cleaning block can directly remove and clean the dust and debris in the rectangular limiting groove, ensuring the smooth and stable movement of the rollers under the first L-shaped plate frame in the rectangular limiting groove. This effectively ensures that the rack in the drive plate can stably and effectively drive the gear, thus ensuring the stability of the planer blade's direction adjustment.

[0032] like Figures 1 to 11 As shown, this utility model relates to a vertical three-line grooving machine, comprising a machine body 1, a worktable 2 slidably arranged on the top of the machine body 1, a clamp 4 arranged on the top front side of the worktable 2, a pressure plate 3 arranged on the top rear side of the worktable 2, a sliding frame 5 arranged on the top of the machine body 1, a fixed plate 6 slidably arranged on the sliding frame 5, and a three-line cutter head structure 7 slidably arranged on the fixed plate 6. The three-line cutter head structure 7 includes an L-shaped mounting plate 8, three sets of equidistant cutter holders 9 rotatably arranged on the horizontal part of the L-shaped mounting plate 8, and planing cutters 10 arranged on the cutter holders 9. The cutter holders 9 penetrate the L-shaped mounting plate 8. A gear 13 is arranged at the top of the flat part. A drive plate 11 is slidably arranged at the top of the horizontal part of the L-shaped mounting plate 8. A first electro-hydraulic push rod 12 is arranged at the top of the horizontal part of the L-shaped mounting plate 8 behind the drive plate 11. The piston end of the first electro-hydraulic push rod 12 is connected to the drive plate 11. The tool holder 9 includes a shaft 901 and a mounting seat 902. The shaft 901 is rotatably arranged on the horizontal part of the L-shaped mounting plate 8. The mounting seat 902 is arranged at the bottom end of the shaft 901 that passes through the horizontal part of the L-shaped mounting plate 8. The planer 10 is arranged on the mounting seat 902 by bolts.

[0033] When grooving the board, the board is first placed on the workbench 2, and then fixed by the clamp 4 and the pressure plate 3. At this time, the planer 10 is initially in a horizontal state. Then, the sliding frame 5, together with the fixed plate 6, drives the three-line cutter head structure 7 to descend and move horizontally. At this time, the three sets of planer blades 10 on the three-line cutter head structure 7 can complete the three-line grooving of the board in the transverse direction. When it is necessary to groove the board in the longitudinal direction, the first electric hydraulic push rod 12 can directly drive the drive plate 11 to move. Then the drive plate 11 drives the gear 13 to rotate 90 degrees. At this time, the gear 13 drives the cutter holder 9 and the planer blades 10 on it to rotate 90 degrees, so that the three sets of planer blades 10 are in a vertical state. Then the workbench 2 drives the board to move back and forth, and the drive structure on the fixed plate 6 drives the three-line cutter head structure 7 to descend. At this time, the three-line grooving of the board in the longitudinal direction can be completed, so that the transverse and longitudinal grooving operations of the board can be quickly realized.

[0034] Specifically, the horizontal part of the L-shaped mounting plate 8 has a rectangular limiting groove 801, and the first L-shaped plate frame 1101 is inserted into the rectangular limiting groove 801; the rectangular limiting groove 801 facilitates the stable lateral movement of the first L-shaped plate frame 1101.

[0035] Furthermore, rectangular bars 201 are arranged on both sides of the bottom of the worktable 2, and an installation bar 202 is arranged in the center of the bottom of the worktable 2. A rectangular opening 101 symmetrical to the rectangular bars 201 is opened on the machine body 1, and the rectangular bars 201 are located in the rectangular opening 101. A rectangular groove 102 corresponding to the installation bar 202 is opened on the machine body 1, and the installation bar 202 is located in the rectangular groove 102. A lead screw 103 is rotatably arranged in the rectangular groove 102, and the lead screw 103 passes through the installation bar 202. A motor 104 is arranged on the front side of the machine body 1, and the rotating shaft of the output end of the motor 104 is connected to the lead screw 103. The rectangular bars 201 and the rectangular opening 101 are used to limit the worktable 2. Then the motor 104 works to drive the lead screw 103 to rotate. Then the lead screw 103, in conjunction with the installation bar 202, drives the worktable 2 to move back and forth.

[0036] In an embodiment of this utility model, the drive plate 11 includes a first L-shaped plate frame 1101, which is slidably arranged on the horizontal part of the L-shaped mounting plate 8. A rack 1102 corresponding to the gear 13 is slidably arranged on the side of the first L-shaped plate frame 1101 facing the gear 13. A second electro-hydraulic push rod 1103 corresponding to the rack 1102 is arranged on the top of the first L-shaped plate frame 1101. The piston end of the second electro-hydraulic push rod 1103 is connected to the corresponding rack 1102.

[0037] When the planer blades 10 are being adjusted for rotation, the operator can use the second electro-hydraulic push rod 1103 on the first L-shaped plate frame 1101 to drive the corresponding rack 1102 to move up and down, thereby adjusting the meshing state of the rack 1102 and the corresponding gear 13. This allows for free adjustment of the rotation of the three sets of planer blades 10 as needed. When single-line or double-line grooving is required on the edge of the board, one or two sets of racks 1102 and gears 13 can be directly controlled to mesh, thus controlling the rotation of one or two sets of planer blades 10. This allows for corresponding unidirectional or double-line grooving of the board edge, thereby improving efficiency. The high-speed planing of the sheet metal requires rapid horizontal and vertical grooving. Furthermore, the three sets of racks 1102, in conjunction with the first L-shaped frame 1101, allow for simultaneous engagement of the three sets of racks 1102 with the three sets of gears 13 when adjusting the direction of the three sets of planer blades 10. The first L-shaped frame 1101 then drives the three sets of racks 1102 to synchronously drive the three sets of gears 13, achieving simultaneous adjustment of the direction of the three sets of planer blades 10. This ensures the coordinated adjustment of the three sets of planer blades 10. Similarly, the coordinated adjustment of the two sets of planer blades 10 also requires no additional calibration, guaranteeing the accuracy of the direction adjustment of the three sets or two sets of planer blades 10.

[0038] Specifically, a T-shaped bar is arranged on the side of the first L-shaped plate frame 1101 facing the rack 1102. A T-shaped groove is opened on the rack 1102, and the T-shaped groove fits onto the T-shaped bar. The T-shaped bar and the T-shaped groove cooperate to facilitate the stable up and down movement of the rack 1102 on the first L-shaped plate frame 1101.

[0039] In an embodiment of this utility model, a stabilizing component 14 is arranged on the front side of the top of the horizontal part of the L-shaped mounting plate 8. The stabilizing component 14 includes a second L-shaped plate frame 1401, which is arranged on the L-shaped mounting plate 8. A third electro-hydraulic push rod 1404 corresponding to the gear 13 is arranged on the top of the second L-shaped plate frame 1401. A block 1403 is arranged on the piston end of the third electro-hydraulic push rod 1404. A square hole 1301 is opened at the center of the top of the gear 13, and the block 1403 corresponds to the square hole 1301. A square tube 1402 corresponding to the block 1403 is arranged at the bottom of the second L-shaped plate frame 1401, and the block 1403 is located inside the square tube 1402.

[0040] When the drive plate 11 drives the gear 13 to rotate to achieve horizontal and vertical adjustment of the planer blade 10, the operator can directly drive the corresponding block 1403 to descend through the third electric hydraulic push rod 1404 in the stabilizing component 14, so that the block 1403 is inserted into the square hole 1301 of the corresponding gear 13, thereby achieving stable positioning of the gear 13. At this time, the upper part of the block 1403 is located inside the square tube 1402, and the square tube 1402 can limit the block 1403 in the horizontal direction, further ensuring the positioning stability of the block 1403 on the gear 13, that is, ensuring the stability of the planer blade 10 after horizontal and vertical adjustment, thereby further ensuring the effect of the planer blade 10 quickly planing the plate horizontally and vertically.

[0041] In an embodiment of this utility model, a number of equidistant rollers 15 are rolled at the bottom of the first L-shaped plate frame 1101. Cleaning structures 16 are arranged at the bottom of both sides of the first L-shaped plate frame 1101. The cleaning structure 16 includes a welding block 1601, a U-shaped frame 1602, a push spring 1603, and a cleaning block 1604. The welding block 1601 is arranged on the first L-shaped plate frame 1101. The U-shaped frame 1602 is inserted into the welding block 1601. The cleaning block 1604 is arranged on the bottom of the welding block 1601 through the U-shaped frame 1602. The push spring 1603 is sleeved on the U-shaped frame 1602 and is located between the welding block 1601 and the cleaning block 1604. The cleaning block 1604 is close to the first L-shaped plate frame 1101, and the side of the cleaning block 1604 facing away from the first L-shaped plate frame 1101 is an inclined scraping edge 1605.

[0042] With the cooperation of the roller shaft 15, the first L-shaped plate frame 1101 generates rolling friction with the rectangular limiting groove 801, reducing friction. While limiting the first L-shaped plate frame 1101, it can ensure that the first L-shaped plate frame 1101 moves more smoothly within the rectangular limiting groove 801. Moreover, when the first L-shaped plate frame 1101 moves, the cleaning block 1604 in the corresponding side cleaning structure 16 will be pushed against the bottom of the rectangular limiting groove 801 by the push spring 1603. Then, the inclined scraper edge 1605 of the cleaning block 1604 can directly remove and clean the dust and debris in the rectangular limiting groove 801, making the inside of the rectangular limiting groove 801 clean. This ensures that the roller shaft 15 under the first L-shaped plate frame 1101 moves smoothly and stably within the rectangular limiting groove 801, which can effectively ensure that the rack 1102 in the drive plate 11 can stably and effectively drive the gear 13, thus ensuring the stability of the rotation adjustment of the planer 10.

[0043] Working principle: This embodiment provides a vertical three-line grooving machine. First, when grooving the board, the board is placed on the workbench 2 and then fixed by the clamp 4 and the pressure plate 3. At this time, the planer 10 is initially in a horizontal state. Then, the sliding frame 5, together with the fixed plate 6, drives the three-line cutter head structure 7 to descend and move horizontally. At this time, the three sets of planer blades 10 on the three-line cutter head structure 7 can complete the three-line grooving of the board in the transverse direction. When it is necessary to groove the board in the longitudinal direction, the first electric hydraulic push rod 12 can drive the drive plate 11 to move directly. Then, the drive plate 11 drives the gear 13 to rotate 90 degrees. At this time, the gear 13 drives the cutter holder 9 and the planer blades 10 on it to rotate 90 degrees, so that the three sets of planer blades 10 are in a vertical state. Then, the workbench 2 drives the board to move back and forth, and the drive structure on the fixed plate 6 drives the three-line cutter head structure 7 to descend. At this time, the three-line grooving of the board in the longitudinal direction can be completed, so that the transverse and longitudinal grooving operations of the board can be quickly realized.

[0044] Secondly, when the planer blades 10 are being adjusted in direction, the operator can use the second electric hydraulic push rod 1103 on the first L-shaped plate frame 1101 to drive the corresponding rack 1102 to move up and down, thereby adjusting the meshing state of the rack 1102 and the corresponding gear 13. This allows for free adjustment of the rotation of the three sets of planer blades 10 as needed. When single-line or double-line grooving is required on the edge of the board, one or two sets of racks 1102 and gears 13 can be directly controlled to mesh, thus controlling the direction of one or two sets of planer blades 10. This allows for corresponding unidirectional or double-line grooving of the board edge, thereby achieving better... To improve the need for rapid horizontal and vertical grooving of boards, and in the form of the three sets of racks 1102 cooperating with the first L-shaped board frame 1101, when adjusting the direction of the three sets of planer blades 10, the three sets of racks 1102 simultaneously mesh with the three sets of gears 13. Then, the first L-shaped board frame 1101 can drive the three sets of racks 1102 to synchronously drive the three sets of gears 13, realizing the simultaneous adjustment of the direction of the three sets of planer blades 10, so that the direction adjustment of the three sets of planer blades 10 has synergy. Similarly, the direction adjustment of the two sets of planer blades 10 also has the same synergy, without the need for additional adjustment, ensuring the accuracy of the direction adjustment of the three sets of planer blades 10 or the two sets of planer blades 10.

[0045] Secondly, after the drive plate 11 drives the gear 13 to rotate to achieve horizontal and vertical adjustment of the planer 10, the operator can directly drive the corresponding block 1403 to descend through the third electric hydraulic push rod 1404 in the stabilizing component 14, so that the block 1403 is inserted into the square hole 1301 of the corresponding gear 13, thereby achieving stable positioning of the gear 13. At this time, the upper part of the block 1403 is located inside the square tube 1402, and the square tube 1402 can limit the block 1403 in the horizontal direction, further ensuring the positioning stability of the block 1403 on the gear 13, that is, ensuring the stability of the planer 10 after horizontal and vertical adjustment, thereby further ensuring the effect of the planer 10 to quickly plan the plate horizontally and vertically.

[0046] Finally, with the cooperation of the roller 15, the first L-shaped plate frame 1101 generates rolling friction with the rectangular limiting groove 801, reducing friction. While limiting the first L-shaped plate frame 1101, it can ensure that the first L-shaped plate frame 1101 moves more smoothly in the rectangular limiting groove 801. Moreover, when the first L-shaped plate frame 1101 moves, the cleaning block 1604 in the corresponding side cleaning structure 16 will be pushed against the bottom of the rectangular limiting groove 801 by the push spring 1603. Then, the inclined scraper edge 1605 of the cleaning block 1604 can directly remove and clean the dust and debris in the rectangular limiting groove 801, making the inside of the rectangular limiting groove 801 clean. This ensures that the roller 15 under the first L-shaped plate frame 1101 moves smoothly and stably in the rectangular limiting groove 801, which can effectively ensure that the rack 1102 in the drive plate 11 can stably and effectively drive the gear 13, thus ensuring the stability of the rotation adjustment of the planer 10.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
