A sawing machine capable of avoiding profiles

Abstract

This utility model relates to the field of machining technology, and in particular to a sawing machine capable of avoiding profiles. It includes a frame, a clamping device, a pressing device, and a sawing device. The clamping device includes a first movable seat and a clamping platform. The clamping platform is equipped with a clamping mechanism. When the profile is moved by the clamping device to the pressing device, the pressing device can press the profile and process it through the sawing device. When the profile is processed and needs to move backward, the pressing device can release the profile. The driving device drives the clamping platform to rotate to the left around the shaft, thereby causing the profile to rotate relative to the pressing device, disengaging the profile from the pressing device. The profile can then be moved backward by moving the first movable seat. When it reaches the corresponding position, the clamping platform can reset, and the pressing device can re-press the profile. This device can prevent friction between the profile and the pressing device during movement, thus avoiding scratches on the profile. Furthermore, the equipment has high precision and low error.

Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a sawing machine that can avoid profiles. Background Technology

[0002] When the profile moves on the sawing machine, it rests against the back plate to ensure the cut is regular. However, since the profile needs to move and adjust relative to the back plate, the back plate is easily worn after long-term use, which reduces the levelness of the back plate and affects the processing accuracy. The back plate needs to be replaced frequently. Therefore, a sawing machine that can effectively prevent the back plate from wearing down the profile has appeared on the market.

[0003] For example, patent CN219944808U discloses a wear-resistant saw head. This wear-resistant saw head includes a frame, on which the saw head is mounted. The saw head includes a horizontally positioned worktable and a vertically positioned fixed seat. The worktable is used for left-right feeding, and the fixed seat is fixedly mounted on the frame. A sliding plate is slidably mounted on the fixed seat. By sliding the sliding plate on the fixed seat, relative movement of the profile with respect to the sliding plate can be effectively prevented, thereby preventing wear on the profile or the left support plate on the sliding plate.

[0004] The problem with the above technology is that when the profile is cut by the saw head, it needs to be fixed and positioned against the left side plate of the sliding plate. When the profile needs to be moved, the sliding plate needs to be moved to prevent the profile from wearing against the left side plate during the movement. When the profile moves to the corresponding position, the sliding plate will reset and make the left side plate abut against the profile. However, the sliding plate is prone to pushing the profile when resetting, causing the profile to deviate. Moreover, the resetting of the sliding plate requires a high degree of precision and is prone to errors.

[0005] To address this issue, a sawing machine capable of avoiding profiles is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a sawing machine that can avoid friction between the profile and the clamping device when the profile moves, thereby preventing the profile from being scratched and achieving high precision.

[0007] The technical solution adopted by this utility model to solve the problem is: a sawing machine capable of avoiding profiles, including a frame, a clamping device, a pressing device, and a sawing device. The clamping device and the pressing device are both mounted on the frame and can move in the front-back direction. The pressing device is located behind the clamping device. The sawing device is mounted on the frame and can move in the left-right direction. The sawing device is located beside the pressing device. The clamping device includes a first movable seat that can move back and forth. The top left and right ends of the first movable seat are respectively provided with a driving device and a bearing seat. It also includes a clamping platform. The bottom left end of the clamping platform is provided with a shaft. The shaft is rotatably connected to the bearing seat. The output shaft of the driving device faces upward and is connected to the bottom right end of the clamping platform. The top of the clamping platform is provided with a clamping mechanism for clamping the profile.

[0008] As a further improvement to the above technical solution, at least one limiting device is provided on the side of the driving device, and the output shaft of the limiting device faces upward and abuts against the bottom of the clamping platform.

[0009] As a further improvement to the above technical solution, the clamping mechanism includes a left clamping part, a right clamping part, and an upper clamping part. The left clamping part and the right clamping part are respectively disposed on the left and right sides of the top of the clamping platform. The left clamping part can move left and right relative to the right clamping part, and the upper clamping part is disposed above the clamping platform and can move up and down relative to the clamping platform.

[0010] As a further improvement to the above technical solution, the sawing device includes a saw blade, and the clamping device includes a second movable seat that can move back and forth. A clamping platform is provided on the second movable seat. A left clamping part and a right clamping part are respectively provided on the left and right sides of the top of the clamping platform. The left clamping part can move left and right relative to the right clamping part. An upper clamping part that can move up and down relative to the clamping platform is also provided above the clamping platform. A first sawing slit is provided on the clamping platform, and a second sawing slit is provided on the front side of the first sawing slit. Both the first sawing slit and the second sawing slit are used to avoid the saw blade.

[0011] As a further improvement to the above technical solution, a clearance groove is provided at the middle position of the left pressing part, the right pressing part and the upper pressing part. The clearance groove is on the same vertical plane as the first saw cut. The left pressing part includes a first left pressing part and a second left pressing part located on the front and rear sides of the clearance groove. The first left pressing part and the second left pressing part can move independently. The upper pressing part includes a first upper pressing part and a second upper pressing part located on the front and rear sides of the clearance groove. The first upper pressing part and the second upper pressing part can move independently.

[0012] As a further improvement to the above technical solution, both the lower ends of the first and second saw cuts are provided with chip removal sections, which are connected to the outside.

[0013] The beneficial effects of this utility model are as follows: When the profile is moved from the clamping device to the pressing device, the pressing device can press the profile and process it through the sawing device. When the profile is processed and needs to be moved backward, the pressing device can release the profile and drive the clamping platform to rotate to the left around the shaft through the driving device, thereby causing the profile to rotate relative to the pressing device, so that the profile is disengaged from the pressing device. The profile can be moved backward by moving the first moving seat. When it moves to the corresponding position, the clamping platform can be reset and the pressing device can press the profile again. This device can avoid friction between the profile and the pressing device during movement, thus preventing scratches on the profile. Moreover, the equipment has high precision and small error.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Reference Figures 1 to 3A sawing machine capable of avoiding profiles includes a frame 1, a clamping device 2, a pressing device 3, and a sawing device 4. The clamping device 2 and the pressing device 3 are both mounted on the frame 1 and can move in the front-back direction. The pressing device 3 is located behind the clamping device 2. The sawing device 4 is mounted on the frame 1 and can move in the left-right direction. The sawing device 4 is located beside the pressing device 3. The clamping device 2 includes a first movable seat 21 that can move back and forth. The top left and right ends of the first movable seat 21 are respectively provided with a drive device 22 and a bearing seat 23. It also includes a clamping platform 24. The bottom left end of the clamping platform 24 is provided with a shaft 25, which is rotatably connected to the bearing seat 23. The output shaft of the drive device 22 faces upward and is connected to the bottom right end of the clamping platform 24. The top of the clamping platform 24 is provided with a clamping mechanism 26, which is used to clamp the profile.

[0029] The frame 1 is equipped with a slide rail arranged along the moving direction of the clamping device 3 and the sawing device 4. The clamping device 2, the clamping device 3 and the sawing device 4 are all driven by a motor, cylinder or hydraulic cylinder.

[0030] For reference Figure 3 When the profile is moved from the clamping device 2 to the pressing device 3, the pressing device 3 can press the profile and process it through the sawing device 4. When the profile is processed and needs to be moved backward, the pressing device 3 can release the profile and drive the clamping platform 24 to rotate to the left around the shaft 25 through the driving device 22, thereby causing the profile to rotate relative to the pressing device 3, so that the profile is disengaged from the pressing device 3. The profile can be moved backward by moving the first moving seat 21. When it moves to the corresponding position, the clamping platform 24 can be reset and the pressing device 3 can press the profile again. This device can avoid friction between the profile and the pressing device 3 during movement, thus preventing the profile from being scratched. The equipment has high precision and small error.

[0031] The drive unit 22 is a motor, cylinder or hydraulic cylinder.

[0032] In a preferred embodiment, at least one limiting device 27 is provided on the side of the driving device 22, and the output shaft of the limiting device 27 faces upward and abuts against the bottom of the clamping platform 24.

[0033] When the clamping platform 24 is in a horizontal position, the output shaft of the limiting device 27 is at the top. When the clamping platform 24 is tilted by the driving device 22, the output shaft of the limiting device 27 disengages from the clamping platform 24. When the clamping platform 24 is reset, the output shaft of the limiting device 27 abuts against the bottom of the clamping platform 24. Since the output shaft of the driving device 22 will have a certain error during the reset process, the limiting device 27 can confirm the horizontal position of the clamping platform 24, which can prevent the driving device 22 from failing to guarantee the horizontal position of the clamping platform 24 after reset.

[0034] The limit device 27 is a motor, cylinder or hydraulic cylinder.

[0035] In the preferred embodiment, as shown in reference Figure 3 The clamping mechanism 26 includes a left clamping part 261, a right clamping part 262 and an upper clamping part 263. The left clamping part 261 and the right clamping part 262 are respectively disposed on the left and right sides of the top of the clamping platform 24. The left clamping part 261 can move left and right relative to the right clamping part 262. The upper clamping part 263 is disposed above the clamping platform 24 and can move up and down relative to the clamping platform 24.

[0036] The clamping mechanism 26 is provided with a slide rail arranged along the moving direction of the left clamping part 261 and the upper clamping part 263. Both the left clamping part 261 and the upper clamping part 263 are driven by a motor, a cylinder or a hydraulic cylinder.

[0037] The profile can be clamped horizontally by moving the left clamping part 261 toward the right clamping part 262, and the profile can be clamped vertically by moving the upper clamping part 263 toward the clamping platform 24.

[0038] In a preferred embodiment, the sawing device 4 includes a saw blade 41, and the clamping device 3 includes a second movable seat 31 that can move back and forth. A clamping platform 32 is provided on the second movable seat 31. A left clamping part 33 and a right clamping part 34 are respectively provided on the left and right sides of the top of the clamping platform 32. The left clamping part 33 can move left and right relative to the right clamping part 34. An upper clamping part 35 that can move up and down relative to the clamping platform 32 is also provided above the clamping platform 32. A first sawing slit 36 ​​is provided on the clamping platform 32, and a second sawing slit 37 is provided on the front side of the first sawing slit 36. Both the first sawing slit 36 ​​and the second sawing slit 37 are used to avoid the saw blade 41.

[0039] For reference Figure 5 and 6 When the profile moves to the pressing platform 32, the left pressing part 33 can move to the right pressing part 34 and press the profile in the horizontal direction, and the upper pressing part 35 can move to the pressing platform 32 and press the profile in the vertical direction. At this time, the saw blade 41 is located on the side of the first sawing slit 36, and the saw blade 41 can move into the first sawing slit 36 ​​and cut the profile.

[0040] For reference Figure 7 and 8 When the profile is cut to the remaining tail material, the tail material is located at the second sawing kerf 37. The second moving seat 31 can move backward so that the second sawing kerf 37 moves to the side of the saw blade 41. The saw blade 41 can move into the second sawing kerf 37 and cut the tail material of the profile.

[0041] The clamping device 3 includes a slide rail arranged along the moving direction of the left clamping part 33 and the upper clamping part 35. Both the left clamping part 33 and the upper clamping part 35 are driven by a motor, a cylinder or a hydraulic cylinder.

[0042] In a preferred embodiment, a relief groove 38 is provided at the middle position of the left pressing part 33, the right pressing part 34 and the upper pressing part 35. The relief groove 38 is on the same vertical plane as the first saw cut 36. The left pressing part 33 includes a first left pressing part 331 and a second left pressing part 332 located on the front and rear sides of the relief groove 38. The first left pressing part 331 and the second left pressing part 332 can move independently. The upper pressing part 35 includes a first upper pressing part 351 and a second upper pressing part 352 located on the front and rear sides of the relief groove 38. The first upper pressing part 351 and the second upper pressing part 352 can move independently.

[0043] When the profile moves to the clamping platform 32, the first left clamping part 331 and the second left clamping part 332 can move to the right clamping part 34 and clamp the profile in the horizontal direction. The first upper clamping part 351 and the second upper clamping part 352 can move to the clamping platform 32 and clamp the profile in the vertical direction. The saw blade 41 can pass through the clearance groove 38 and the first sawing kerf 36 and cut the profile, dividing the profile into the front half and the back half. Then the second left clamping part 332 and the second upper clamping part 352 can be reset, thereby releasing the back half of the profile. At this time, the back half can be removed from the clamping platform 32 by manual labor or a robot.

[0044] In a preferred embodiment, the lower ends of both the first sawing slit 36 ​​and the second sawing slit 37 are provided with chip removal parts 5, which are in communication with the outside.

[0045] The iron filings generated when the saw blade 41 cuts the profile can be discharged to the outside through the chip removal part 5, which is an inclined plate.

[0046] Usage steps:

[0047] S1. The profile is placed on the clamping platform 24 by manual or robotic arm. The left clamping part 261 can move to the right clamping part 262 and clamp the profile in the horizontal direction. The upper clamping part 262 can move to the clamping platform 24 and clamp the profile in the vertical direction.

[0048] S2. When moving the profile, the drive device 22 drives the clamping platform 24 to rotate to the left around the shaft 25, thereby causing the profile to rotate and causing the profile to be misaligned with the pressing platform 32 and the right pressing part 34. When the first moving seat 21 moves towards the pressing device 3, the profile can pass through the pressing platform 32 and the right pressing part 34. When the profile moves to the corresponding position, the drive device 22 can drive the clamping platform 24 to reset to the horizontal position, so that the profile abuts against the pressing platform 32 and the right pressing part 34. Then the left pressing part 32 can move towards the right pressing part 34 and press the profile in the horizontal direction. The upper pressing part 35 can move towards the pressing platform 32 and press the profile in the vertical direction. At this time, the first sawing slit 36 ​​is located on the side of the saw blade 41. The profile can be cut into the front half and the back half by passing the saw blade 41 through the first sawing slit 36.

[0049] S3. After the profile is cut, the second left clamping part 332 and the second upper clamping part 352 can be reset to release the rear half of the profile. The rear half of the profile can be removed from the clamping platform 32 by manual labor or a robot. Then the first left clamping part 331 and the first upper clamping part 351 can be reset to release the front half of the profile, and the steps of S2 continue until the remaining tail material of the profile is cut.

[0050] S4. When the tail of the profile moves to the clamping platform 32, the left clamping part 32 can move to the right clamping part 34 and clamp the tail of the profile in the horizontal direction. The upper clamping part 35 can move to the clamping platform 32 and clamp the tail of the profile in the vertical direction. Then the left clamping part 261 and the upper clamping part 262 will reset and release the tail of the profile. The driving device 22 can drive the clamping platform 24 to rotate to the right around the shaft 25, so that the right clamping part 262 and the clamping platform 24 are disengaged from the contact of the tail of the profile. Then the first moving seat 21 can move forward to the initial position. The driving device 22 can then drive the clamping platform 24 to reset to the horizontal position.

[0051] S5. The second moving seat 31 can move the tail of the profile backward, so that the second sawing kerf 37 moves to the side of the saw blade 41. Then the saw blade 41 can pass through the second sawing kerf 37 and cut the tail of the profile. After the tail of the profile is cut, the left clamping part 32 and the upper clamping part 35 will reset and release the profile. Then the profile can be unloaded from the clamping platform 32 by manual or robotic arm. Then the second moving seat 31 can move forward to the initial position, so that the first sawing kerf 36 moves to the side of the saw blade 41, and continue the steps of S1.
