Description

Technical Field

[0001] This utility model relates to the technical field of glass and stone edge grinding equipment, and in particular to a flip-type upper chamfering grinding head and edge grinding machine. Background Technology

[0002] The chamfering grinding head mechanism in an edge grinding machine generally consists of a cutting blade, a grinding wheel, and a drive motor. In traditional structures, the chamfering grinding head mechanism is fixedly mounted on the frame of the edge grinding machine. When the cutting blade or grinding wheel in the chamfering grinding head mechanism needs to be replaced or maintained, either the entire chamfering grinding head mechanism must be disassembled or the outer cover must be removed before disassembly and maintenance can be performed through the narrow gap between the chamfering grinding head mechanism and the frame. This is extremely inconvenient for workers to maintain, and the time required to replace the cutting blade and grinding wheel is relatively long. Since the cutting blade and grinding wheel are consumable parts, they need to be replaced frequently. Long downtime for equipment replacement will seriously slow down production efficiency.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] This embodiment features a flip-type upper chamfering grinding head, such as... Figure 1-5 As shown, the device includes a frame 1, a grinding head mechanism 2, a bearing seat 3, and a telescopic cylinder 4. The frame 1 is provided with a mounting platform 11, and the bearing seat 3 is fixed to both sides of the mounting platform 11. The grinding head mechanism 2 includes a grinding head assembly 21, a mounting plate 22, and a rotating shaft 23. The grinding head assembly 21 is disposed on the top surface of the mounting plate 22, and the rotating shaft 23 is disposed on one end of the inner side of the bottom surface of the mounting plate 22. Both ends of the rotating shaft 23 are rotatably connected to the bearing seat 3. One end of the telescopic cylinder 4 is hinged to the frame 1, and the other end is hinged to the bottom surface of the mounting plate 22.

[0030] The mounting platform 11 provides mounting space for the grinding head mechanism 2, allowing the bearing seat 3 to be fixedly mounted on the frame 1. The mounting plate 22 is rotatably connected to the bearing seat 3 via a rotating shaft 23, enabling the grinding head mechanism 2 fixed on the mounting plate 22 to rotate together with the mounting plate 22. The two ends of the telescopic cylinder 4 are respectively hinged to the frame 1 and the mounting plate 22. The telescopic cylinder 4 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. When the piston rod of the telescopic cylinder 4 extends, as... Figure 1-3 As shown, the outer side of the mounting plate 22 can be lifted upwards, thereby driving the mounting plate 22 to rotate around the pivot 23, which in turn drives the front end of the grinding head mechanism 2 to press down, causing the cutting blade 215 and grinding wheel 216 mounted on the grinding head mechanism 2 to tilt at a certain angle to process the side of the plate; when the piston rod of the telescopic cylinder 4 retracts, as Figure 4 As shown, the drive mounting plate 22 rotates around the shaft 23, thereby lifting the front end of the grinding head mechanism 2 upwards. This causes the cutting blade 215 and grinding wheel 216 of the grinding head mechanism 2 to move upwards away from the processing area on the frame 1. This provides a larger working space when replacing the cutting blade 215 and grinding wheel 216 of the grinding head mechanism 2, making the replacement of the cutting blade 215 and grinding wheel 216 more convenient and efficient, reducing downtime and improving production efficiency.

[0031] Furthermore, such as Figure 2 As shown, it also includes an adjustment seat 5, which is fixed to both sides of the mounting platform 11 and is located outside the bearing seat 3; the grinding head mechanism 2 also includes an adjustment shaft assembly 24, which is disposed on the outer side of the bottom surface of the mounting plate 22 and parallel to the rotating shaft 23; the adjustment seat 5 is provided with an arc-shaped sliding groove 51, and the adjustment shaft assembly 24 slides in cooperation with the arc-shaped sliding groove 51.

[0032] When the piston rod of the telescopic cylinder 4 extends or retracts, the mounting plate 22 rotates around the pivot shaft 23. At this time, the adjusting shaft assembly 24 slides along the arc-shaped slide groove 51. The arc-shaped slide groove 51 guides the adjusting shaft assembly 24, making the upward rotation of the mounting plate 22 more stable. The two ends of the arc-shaped groove can limit the adjustment shaft assembly 24. When the adjusting shaft assembly 24 slides upward along the arc-shaped groove to the position of the required angle of the grinding head mechanism 2, the grinding head mechanism 2 is in the working position. When the adjusting shaft 241 slides downward to the lowest point, the grinding head mechanism 2 is in the maintenance position.

[0033] Furthermore, such as Figure 5 As shown, the adjusting shaft assembly 24 includes an adjusting shaft 241, an outer washer 242, and a locking bolt 243. The adjusting shaft 241 is disposed at both ends of the outer side of the mounting plate 22. The end of the adjusting shaft 241 facing the adjusting seat 5 has a stepped portion 2411, which slides in cooperation with the arc-shaped sliding groove 51. The outer washer 242 is sleeved on the stepped portion 2411 and is located on the outer side of the adjusting seat 5. The locking bolt 243 is threaded to the outer end face of the adjusting shaft 241 to press the outer washer 242 against the outer wall of the adjusting seat 5.

[0034] The locking bolt 243 is threaded to the end face of the adjusting shaft 241, which can press the outer washer 242 against the outer wall of the adjusting seat 5. This utilizes the friction between the outer washer 242 and the adjusting seat 5 to position the mounting plate 22. Specifically, in actual use, the telescopic cylinder 4 is first driven to extend its piston rod. The mounting plate 22 rotates upward under the drive of the piston rod until the adjusting shaft 241 slides upward along the arc-shaped groove 51 to the required angle position of the grinding head mechanism 2. At this point, the locking bolt 243 is locked to the adjusting shaft 241, pressing the outer washer 242 against the outside of the adjusting seat 5. The huge friction between the outer washer 242 and the adjusting seat 5 can fix the mounting plate 22 to the adjusting seat 5. Even after removing the power source of the telescopic cylinder 4, such as high-pressure gas or hydraulic oil, the mounting plate 22 can still remain in the working position and will not slide down under gravity. This design... This avoids the need for the telescopic cylinder 4 to maintain continuous power to support the mounting plate 22. When it is necessary to replace the cutting blade 215 or grinding wheel 216 of the grinding head mechanism 2, first input the power source, such as high-pressure gas or hydraulic oil, into the telescopic cylinder 4, then loosen the locking bolt 243, and then slowly reduce the pressure of the high-pressure gas or hydraulic oil to allow the mounting plate 22 to slowly descend until the adjusting shaft 241 abuts against the bottom of the arc-shaped slide groove 51. This can prevent the mounting plate 22 from falling rapidly due to sudden loss of support. After replacing the cutting blade or grinding wheel 216, slowly increase the pressure of the high-pressure gas or hydraulic oil to allow the mounting plate 22 to slowly rotate upward until the adjusting shaft 241 abuts against the top of the arc-shaped slide groove 51. At this time, tighten the locking bolt 243, and then remove the power source of the telescopic cylinder 4. The telescopic cylinder 4 only works when the mounting plate 22 needs to rotate, which can effectively increase the service life of the telescopic cylinder 4.

[0035] Furthermore, the adjusting shaft assembly 24 also includes an inner washer 244, which is sleeved on the step portion 2411 and located inside the adjusting seat 5. One side of the inner washer 244 abuts against the adjusting seat 5, and the other side abuts against the step of the step portion 2411.

[0036] When the locking bolt 243 is tightened, the adjusting seat 5 can be clamped by the cooperation of the inner washer 244 and the outer washer 242. By setting the inner washer 244, the contact area between the adjusting shaft assembly 24 and the adjusting seat 5 can be increased, which not only makes the locking bolt 243 more secure after tightening, but also prevents the mounting plate 22 from shaking along the axis of the adjusting shaft 241, making the grinding head mechanism 2 more stable when processing the plate and resulting in higher product quality.

[0037] Furthermore, such as Figure 2-5As shown, the grinding head assembly 21 includes a cutting motor 211, a cutting slide 212, a grinding motor 213, and a grinding slide 214. The cutting slide 212 and the grinding slide 214 are arranged side by side on the upper surface of the mounting plate 22. The cutting motor 211 is disposed on the cutting slide 212, and a cutting blade 215 is installed at the output end of the cutting motor 211. The grinding motor 213 is disposed on the grinding slide 214, and a grinding wheel 216 is disposed at the front end of the grinding motor 213.

[0038] The cutting motor 211 is mounted on the cutting slide 212. The distance between the cutting motor 211 and the edge of the material can be changed by adjusting the cutting slide 212, thereby adjusting the depth of the chamfer. Similarly, the distance between the grinding motor 213 and the material can be adjusted by adjusting the grinding slide 214, so that the grinding wheel 216 can grind the chamfered surface after cutting. The cutting slide 212 and the grinding slide 214 are existing structures and can be purchased from the market, such as a hand-cranked dovetail groove linear slide or an electric linear slide, etc., and are not specifically limited here.

[0039] Furthermore, such as Figure 3 and 5 As shown, the bottom of the grinding slide 214 is provided with a support base 217, which is disposed between the grinding slide 214 and the mounting plate 22.

[0040] It should be noted that the cutting blade 215 cuts the board by its edge, thereby creating a chamfer on the edge of the board, while the grinding wheel 216 grinds the chamfered surface of the board by contacting the end face of the grinding wheel 216 with the chamfered surface of the board. By setting the support base 217, the grinding motor 213 can be raised so that the middle part of the grinding wheel 216 contacts the chamfered surface of the board, thereby increasing the contact area between the grinding wheel 216 and the board and increasing the grinding efficiency.

[0041] Furthermore, such as Figure 2-4 As shown, the frame 1 is equipped with a water tank 12, and the water tank 12 has a water tank opening 13; as Figure 4 and 5 As shown, the grinding head mechanism 2 also includes a water tank cover 25 and a bracket 26. The bracket 26 is disposed on the cutting slide 212 and the grinding slide 214. The water tank cover 25 is installed on the water tank bracket and is used to cover the water tank opening 13.

[0042] During the cutting and grinding process, water needs to be continuously poured onto the board to prevent the board, cutting tools, and grinding wheel 216 from overheating, and to wash away the dust generated during processing. To prevent water from splashing outside the equipment and polluting the production environment, a water tank 12 needs to be installed on the frame 1 along the path of the board to contain the water. Innovatively, the water tank cover 25 is connected to the cutting slide 212 and the grinding slide 214 via a bracket 26. During processing, the water tank cover is placed over the water tank opening 13 to provide waterproofing. When changing the cutting blade 215 or the grinding wheel 216, the water tank cover 25 is removed from the water tank opening 13 to provide operating space for changing the cutting blade 215 and the grinding wheel 216.

[0043] like Figure 3 and Figure 5 As shown, the water tank cover 25 is provided with a first through hole 251 and a second through hole 252. The output end of the cutting motor 211 extends into the water tank 12 through the first through hole 251, and the output end of the grinding motor 213 extends into the water tank 12 through the second through hole 252.

[0044] With this configuration, the output ends of the cutting motor 211 and the grinding motor 213 can be inserted into the water tank 12 to process the sheet material that has passed through the water tank 12.

[0045] like Figure 3 and Figure 5 As shown, the frame 1 is provided with a lower hinge seat 14, the bottom surface of the mounting plate 22 is provided with an upper hinge seat 27, the cylinder end of the telescopic cylinder 4 is hinged to the lower hinge seat 14, the piston rod of the telescopic cylinder 4 is equipped with a fisheye connector 41, and the fisheye connector 41 is hinged to the upper hinge seat 27.

[0046] By installing a fisheye connector 41 on the piston rod of the telescopic cylinder 4, the installation accuracy requirements of the upper hinge seat 27 and the lower hinge seat 14 can be effectively reduced, and the problem of uneven wear at the hinge shaft of the upper hinge seat 27 or the lower hinge seat 14 due to installation deviation can be effectively avoided.
