Description

Technical Field

[0001] This utility model relates to the field of grooving machine technology, and more specifically, to a three-plus-one-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 grooving machines typically use a single-line grooving method. When multi-line grooving of a board is required, the board position needs to be constantly adjusted to achieve multi-line grooving. Although this method can achieve the effect of multi-line grooving, it requires constant adjustment of the board, which is prone to errors and has low grooving efficiency. Therefore, existing grooving machines are not suitable for simultaneous multi-line grooving of boards. In view of this, we propose a three-plus-one-line grooving machine. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a three-plus-one-line grooving machine to solve the technical problem that the current grooving machine is not convenient for simultaneously grooving multiple lines on the board.

[0006] A rectangular groove is provided on the front side of the tool holder. Limiting posts are arranged at the four corners of the rectangular groove, and an adjusting screw is arranged in the center of the rectangular groove. The upper part of the planer is a rectangular section, and the lower part of the planer is the tool head. The rectangular section is located in the rectangular groove. The limiting posts pass through the limiting holes, and the adjusting screw passes through the threaded holes.

[0007] Preferably, the three-line tool holder and the single-line tool holder are symmetrically arranged with T-shaped strips on one side facing the mounting plate, and the surface of the mounting plate is provided with T-shaped grooves corresponding to the T-shaped strips, with the T-shaped strips located in the T-shaped grooves.

[0008] Preferably, the three-line tool holder has three sets of fixing slots equidistantly spaced at the bottom front side, the single-line tool holder has one set of fixing slots at the bottom front side, and a fixing block is arranged at the top of the tool holder, and the fixing block is fixed in the fixing slot by bolts.

[0009] Preferably, a positioning structure is fitted onto the hexagonal end of the adjusting screw. The positioning structure includes an outer ring, an inner ring that is rotatably arranged inside the outer ring, a hexagonal hole corresponding to the hexagonal end of the adjusting screw being opened in the center of the inner ring, and three sets of fixing bolts that are equidistantly arranged around the outer ring. A clamping plate is rotatably arranged at one end of the fixing bolts that penetrates into the outer ring.

[0010] Preferably, a groove is formed around the outer circumference of the inner ring, the clamping plate is located in the groove, a rubber layer is provided in the groove, and anti-slip textures are provided on the opposite surfaces of the rubber layer and the clamping plate.

[0011] Preferably, a positioning rod is arranged at the top of the outer ring, a concave groove is arranged at the top of the positioning rod, a pin hole is opened at the bottom center of the concave groove, a rectangular block is arranged at the top center of the front side of the tool holder, and a positioning pin is inserted into the top center of the rectangular block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features independent three-line and single-line tool holders arranged on a mounting plate, with two sets of electro-hydraulic push rods on the mounting plate. These two sets of push rods allow independent control of the three-line and single-line tool holders. The three-line tool holder has three tool supports, and the single-line tool holder has one tool support. Each tool support contains planing blades, and the four planing blades are staggered. Therefore, when planing grooves into the board, the operator can lower the three-line tool holder using the electro-hydraulic push rods, allowing the three planing blades on the three-line tool holder to simultaneously plan three lines into grooves into the board. Alternatively, the single-line tool holder can be lowered using the electro-hydraulic push rods. Then, a single set of planers on the single-line tool holder can perform single-line grooving on the board, or the electric hydraulic push rod can simultaneously control the descent of the three-line tool holder and the single-line tool holder. Then, the single set of planers on the single-line tool holder and the three sets of planers on the three-line tool holder can simultaneously perform four-line grooving on the board. In summary, this equipment can simultaneously achieve single-line, three-line, and four-line grooving effects on the board, providing versatility in grooving the board. Moreover, synchronous multi-line grooving can also ensure the accuracy of multi-line grooving on the board, solving the technical problem that current grooving machines are not convenient for simultaneous multi-line grooving of boards. Therefore, this utility model has the advantage of better multi-line grooving effect on boards.

[0014] 2. The tool holder of this utility model adopts a rectangular groove, a limiting post, and an adjusting screw design. The planer blade adopts a rectangular part and a blade head design. The rectangular part fits into the rectangular groove, and then the limiting hole of the rectangular part is inserted into the limiting post for limiting. The adjusting screw passes through the threaded hole of the rectangular part. Therefore, when performing multi-line grooving, the operator can turn the adjusting screw according to the required grooving spacing, thereby driving the corresponding planer blade to move back and forth in the rectangular groove. That is, the misalignment spacing of the four sets of planer blades can be adjusted so that the grooving spacing can meet the requirements of the board when performing multi-line grooving, thereby further improving the effect of grooving the board.

[0015] 3. This utility model features a positioning structure on the hexagonal end of the adjusting screw. After adjusting the position of the planer by turning the adjusting screw, the hexagonal hole of the inner ring in the positioning structure can be directly fitted onto the hexagonal end of the adjusting screw. Then, the outer ring is rotated so that the positioning rod on the outer ring is vertically upward. The positioning structure is then pushed backward so that the concave groove at the top of the positioning rod is inserted into the rectangular block. The positioning pin on the rectangular block is then inserted into the pin hole, thus fixing the positioning rod. The operator can then turn the fixing bolt, and the clamping plate is clamped to the inner ring by friction, thus positioning the inner ring. The inner ring can also position the adjusting screw, preventing it from rotating. Therefore, during the grooving process, the rotation of the adjusting screw can be effectively prevented from causing displacement of the planer and resulting in deviation in the grooving. This further ensures the effectiveness of multi-line grooving of the board. Attached Figure Description

Detailed Implementation

[0025] like Figures 1 to 6 As shown, this utility model relates to a three-line grooving machine, including a machine body 1, a sliding frame 2 arranged on the top of the machine body 1, several sets of pressure plates 3 equidistantly arranged at the lower front end of the sliding frame 2, clamps 4 symmetrically arranged on the top front side of the machine body 1, a worktable 5 arranged on the top of the machine body 1, a cutter head structure 6 arranged on the front side of the sliding frame 2, the cutter head structure 6 including a mounting plate 7, the mounting plate 7 arranged on the transverse drive structure of the sliding frame 2, and a three-line cutter holder 9 and a single-line cutter holder slidably arranged on the front side of the mounting plate 7. The tool holder 10 has two sets of electro-hydraulic push rods 8 arranged on the mounting plate 7. The piston end of one set of electro-hydraulic push rods 8 is connected to the three-line tool holder 9, and the piston end of the other set of electro-hydraulic push rods 8 is connected to the single-line tool holder 10. Three sets of tool holders 12 are arranged at equal intervals at the bottom of the three-line tool holder 9, and one set of tool holders 12 is arranged at the bottom of the single-line tool holder 10. Planing blades 13 are arranged inside the tool holders 12, and the four sets of planing blades 13 are staggered. The worktable 5 can move back and forth, which is achieved by a servo motor and a lead screw.

[0026] When grooving the board, the board is placed on the workbench 5, and then the workbench 5 moves the board to adjust its position. The board is then fixed in place by the clamp 4 and the workbench 5. Once the board is in place, the operator can use the electric hydraulic push rod 8 to lower the three-line cutter holder 9, and the three sets of planers 13 on the three-line cutter holder 9 can simultaneously perform three-line grooving on the board. Alternatively, the electric hydraulic push rod 8 can be used to lower the single-line cutter holder 10, and the single set of planers 13 on the single-line cutter holder 10 can perform single-line grooving on the board. Or, the electric hydraulic push rod 8 can be used to simultaneously control the descent of the three-line cutter holder 9 and the single-line cutter holder 10, and the single set of planers 13 on the single-line cutter holder 10 and the three sets of planers 13 on the three-line cutter holder 9 can simultaneously perform four-line grooving on the board. In summary, this equipment can simultaneously achieve single-line, three-line, and four-line grooving effects on the board, providing versatility in board grooving. Moreover, simultaneous multi-line grooving can also ensure the accuracy of multi-line grooving on the board.

[0027] Specifically, the three-line tool holder 9 and the single-line tool holder 10 are symmetrically arranged with T-shaped strips 901 facing one side of the mounting plate 7. The surface of the mounting plate 7 is provided with T-shaped grooves 701 corresponding to the T-shaped strips 901, and the T-shaped strips 901 are located in the T-shaped grooves 701. The T-shaped strips 901 on the rear side of the three-line tool holder 9 and the single-line tool holder 10 are located in the T-shaped grooves 701 of the mounting plate 7, which can ensure that the three-line tool holder 9 and the single-line tool holder 10 can slide stably up and down on the mounting plate 7.

[0028] Furthermore, the three-line tool holder 9 has three sets of fixing slots 11 equidistantly opened at the bottom front side, and the single-line tool holder 10 has one set of fixing slots 11 opened at the bottom front side. The tool holder 12 has a fixing block 1206 arranged at the top, and the fixing block 1206 is fixed in the fixing slot 11 by bolts. When installing the tool holder 12, it is mainly done by inserting the fixing block 1206 at its top into the fixing slot 11 and then tightening it with bolts, which makes it easy to disassemble and assemble the tool holder 12.

[0029] In an embodiment of this utility model, a rectangular groove 1201 is provided on the front side of the tool holder 12. Limiting posts 1202 are arranged at the four corners of the rectangular groove 1201. An adjusting screw 1203 is arranged in the center of the rectangular groove 1201. The upper part of the planer 13 is a rectangular part 1301, and the lower part of the planer 13 is a tool head 1302. The rectangular part 1301 is located in the rectangular groove 1201. The limiting posts 1202 pass through the limiting hole 1303, and the adjusting screw 1203 passes through the threaded hole 1304.

[0030] When performing multi-line grooving on the board, the operator can adjust the grooving spacing by turning the hexagonal end of the adjusting screw 1203. With the limiting action of the limiting post 1202, the corresponding planer blade 13 will move back and forth within the rectangular groove 1201. This allows for adjustment of the staggered spacing of the four sets of planer blades 13, ensuring that the groove spacing meets the requirements of the board during multi-line grooving and further improving the grooving effect.

[0031] In this embodiment of the present invention, a positioning structure 14 is fitted onto the hexagonal end of the adjusting screw 1203. The positioning structure 14 includes an outer ring 1401, an inner ring 1402 rotatably arranged inside the outer ring 1401, and a hexagonal hole 1406 corresponding to the hexagonal end of the adjusting screw 1203 is opened in the center of the inner ring 1402. Three sets of fixing bolts 1404 are equidistantly arranged around the outer ring 1401. A clamping plate 1405 is rotatably arranged at one end of the fixing bolts 1404 that penetrate into the inner ring 1401. 02 A groove 1403 is provided around the outer circumference, and a clamping plate 1405 is located in the groove 1403. A rubber layer is provided in the groove 1403, and anti-slip textures are provided on the opposite surfaces of the rubber layer and the clamping plate 1405. A positioning rod 1407 is arranged at the top of the outer ring 1401, and a concave groove 1408 is arranged at the top of the positioning rod 1407. A pin hole 1409 is provided at the bottom center of the concave groove 1408. A rectangular block 1204 is arranged at the top center of the front side of the tool holder 12, and a positioning pin 1205 is inserted into the top center of the rectangular block 1204.

[0032] After adjusting the position of the planer 13 by turning the adjusting screw 1203, the hexagonal hole 1406 of the inner ring 1402 in the positioning structure 14 can be directly fitted onto the hexagonal end of the adjusting screw 1203. Then, rotate the outer ring 1401 so that the positioning rod 1407 on the outer ring 1401 is vertically upward. Then, push the positioning structure 14 backward so that the concave groove 1408 at the top of the positioning rod 1407 is inserted into the rectangular block 1204. Then, insert the positioning pin 1205 on the rectangular block 1204 into the pin hole 1409. At this time, the positioning rod 1407 can be adjusted. 7. After positioning and fixing, the operator can tighten the fixing bolt 1404. Then, relying on the friction of the rubber layer and anti-slip texture, the clamping plate 1405 clamps the inner ring 1402. At this time, the inner ring 1402 can be positioned. Then, the inner ring 1402 can position the adjusting screw 1203 through the hexagonal hole 1406, preventing it from rotating. Therefore, during the grooving process, the rotation of the adjusting screw 1203 can be effectively avoided, which would cause the planer 13 to shift and cause deviation in grooving. This further ensures the effect of multi-line grooving of the board.

[0033] Working Principle: This embodiment provides a three-line grooving machine. First, when grooving the board, the board is placed on the worktable 5. Then, the worktable 5 moves the board to adjust its position. The board is then fixed by the clamp 4 and the worktable 5. Once the board is in position, the operator can use the electric hydraulic push rod 8 to lower the three-line cutter holder 9. The three sets of planing blades 13 on the three-line cutter holder 9 can then perform three-line grooving on the board simultaneously. Alternatively, the electric hydraulic push rod 8 can be used to lower the single-line cutter holder 10. The single-line cutter 13 on the single-line cutter holder 10 can perform single-line grooving on the board, or the electric hydraulic push rod 8 can simultaneously control the three-line cutter holder 9 and the single-line cutter holder 10 to descend, and then the single-line cutter 13 on the single-line cutter holder 10 and the three-line cutter 13 on the three-line cutter holder 9 can simultaneously perform four-line grooving on the board. In summary, this equipment can simultaneously achieve single-grooving, three-grooving and four-grooving effects on the board, and has the versatility of grooving the board. Moreover, the synchronous multi-line grooving can also ensure the accuracy of multi-line grooving on the board.

[0034] Secondly, when performing multi-line grooving on the board, the operator can adjust the grooving spacing by turning the hexagonal end of the adjusting screw 1203. With the limiting action of the limiting post 1202, the corresponding planer blade 13 will move back and forth within the rectangular groove 1201. This allows the staggered spacing of the four sets of planer blades 13 to be adjusted so that the groove spacing meets the requirements of the board during multi-line grooving, thereby further improving the effect of grooving the board.

[0035] Finally, after adjusting the position of the planer 13 by turning the adjusting screw 1203, the hexagonal hole 1406 of the inner ring 1402 in the positioning structure 14 can be directly fitted onto the hexagonal end of the adjusting screw 1203. Then, rotate the outer ring 1401 so that the positioning rod 1407 on the outer ring 1401 is vertically upward. Then, push the positioning structure 14 backward so that the concave groove 1408 at the top of the positioning rod 1407 is inserted into the rectangular block 1204. Then, insert the positioning pin 1205 on the rectangular block 1204 into the pin hole 1409. At this time, the positioning rod 1407 can be adjusted. Positioning and fixing are performed at 407. Then, personnel can tighten the fixing bolts 1404. The friction of the rubber layer and anti-slip texture causes the clamping plate 1405 to clamp the inner ring 1402. At this time, the inner ring 1402 can be positioned. Then, the inner ring 1402 can position the adjusting screw 1203 through the hexagonal hole 1406, preventing it from rotating. Therefore, during the grooving process, the rotation of the adjusting screw 1203 can be effectively avoided, which would cause the planer 13 to shift and cause deviation in grooving. This further ensures the effect of multi-line grooving of the board.
