Description

Technical Field

[0001] The utility model relates to the technical field of profile processing devices, in particular to a scratch-resistant clamping mechanism and a sawing machine. Background Art

[0002] In the processing of long strip profiles, manual feeding is time-consuming and labor-intensive, so a feeding device is generally provided. The feeding device generally includes a machine table with rollers connected to the machine table for transmission. A processing mechanism is provided at one end of the machine table. The profile is conveyed to the processing mechanism by the rollers. When the processing mechanism processes the profile, the rollers will stop rolling. At this time, the profile is prone to deviation due to inertia. Therefore, most feeding devices on the market will be provided with a clamping mechanism to control the moving position of the profile through the clamping mechanism.

[0003] For example, the patent with publication number CN217452337U discloses a profile cutting device that is convenient for automatically pulling residual tailings, wherein a supporting device is fixedly connected to the right side surface of a processing table, a first pulling device is fixedly installed on the upper surface of the left end of the processing table, and a second pulling device is fixedly installed on the upper surface of the left end of a supporting plate, and the profile tailings can be pulled to the right by the first pulling device and the second pulling device through the supporting device and then clamped and fixed, the support bar of the feed device is fixedly installed on the upper surface of the left end of the processing table and is flush with the upper surface of the supporting plate, and the first screw of the feeding device is threadedly connected to the feeding block, so that the fixing device can be moved left and right to transport the profile;

[0004] The device clamps the profile by a feeding block and drives the feeding block to move the profile by a first screw. Figure 1 It can be seen that the feed block will clamp the middle part of the profile during the process of pushing the profile. After the front end of the profile is processed, the feed block can release the middle part of the profile and move backward, thereby clamping the rear end of the profile, so that the feed block can continue to push the profile, and repeat this process, which is convenient for pushing long strips of profile. However, in the process of repeatedly clamping and pushing the profile, due to the weight of the profile itself or the shape of the profile itself, the part of the profile will be lower than the plane of the feed block. Therefore, the feed block is easy to scratch the profile during the movement, thereby scratching the surface of the profile, affecting the yield of the profile.

[0005] Therefore, an anti-scratch feeding device is proposed to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a scratch-proof clamping mechanism and a sawing machine, which can prevent the clamping mechanism from scratching the profile in the process of pushing the profile.

[0030] Reference Figures 2 to 7, an anti-scratch clamping mechanism, comprising a moving seat 1, a clamping base plate 21 is movably arranged on the moving seat 1, and a first cylinder 22 for driving the clamping base plate 21 to move up and down is arranged on the moving seat 1; a mounting portion 11 is arranged at the side end of the moving seat 1, and a first slide rail 31 and a first drive motor 32 are arranged horizontally along the left and right directions on the mounting portion 11, a clamping side plate 33 is slidably connected to the first slide rail 31, and the clamping side plate 33 is located beside the clamping base plate 21, and the first drive motor 32 is used to drive the clamping side plate 33 to move; a gantry 12 is arranged on the moving seat 1, and a second slide rail 41 and a second drive motor 42 are arranged horizontally along the left and right directions on the gantry 12, a first clamping arm 43 is slidably connected to the second slide rail 41, and the first clamping arm 43 is located above the clamping base plate 21, and the second drive motor 42 is used to drive the first clamping arm 43 to move;

[0031] When clamping the profile, the first cylinder 22 drives the clamping base plate 21 to move upward and abut against the bottom surface of the profile, the first drive motor 32 drives the clamping side plate 33 and the second drive motor 42 drives the first clamping arm 43 to clamp the side of the profile; when adjusting the clamping position of the profile, the first cylinder 22 drives the clamping base plate 21 to move downward and disengage from the bottom surface of the profile, the first drive motor 32 drives the clamping side plate 33 and the second drive motor 42 drives the first clamping arm 43 to disengage from the side of the profile; when adjusting the clamping position of the profile, the clamping base plate 21, the clamping side plate 33 and the first clamping arm 43 do not abut against the profile, thereby preventing the movable seat 1 from scratching the profile during movement.

[0032] In a preferred embodiment, a vertical third slide rail 51 and a third drive motor 52 are provided on the gantry 12, a second clamping arm 53 is slidably connected to the third slide rail 51, the second clamping arm 53 is located above the clamping bottom plate 21, and the third drive motor 52 is used to drive the second clamping arm 53 to move;

[0033] By clamping the profile in the vertical direction by the second clamping arm 53 and the clamping base plate 21 , deviation during processing of the profile can be prevented.

[0034] In a preferred embodiment, a slide groove 14 is provided between the moving seat 1 and the clamping base plate 21, a support rod 15 is slidably connected in the slide groove 14, a third cylinder 17 for driving the support rod 15 to move is provided on the moving seat 1, a support block 16 is provided on the support rod 15, and a groove 211 is provided at the bottom of the clamping base plate 21;

[0035] When the second clamping arm 53 and the clamping base plate 21 clamp the profile in the vertical direction, the clamping base plate 21 is prone to move downward due to the unstable air pressure of the cylinder, and the profile is prone to deformation. Therefore, when the clamping base plate 21 moves upward, the third cylinder 17 drives the support rod 15 to move forward. At this time, the support block 16 abuts against the bottom of the clamping base plate 21, and the clamping base plate 21 cannot move downward.

[0036] When the profile is to be released, the third cylinder 17 drives the support rod 15 to move backward, so that the support block 16 is located below the groove 211, and the clamping bottom plate 21 can move downward.

[0037] In a preferred embodiment, a first roller 13 is provided at the end of the movable seat 1;

[0038] When the clamping base plate 21 moves downward, the profile still abuts against the top end of the first roller 13, which can prevent the profile from being affected by its own gravity or shape when the moving seat 1 changes the clamping position of the profile, and part of its surface will be lower than the clamping base plate 21. During the movement of the moving seat 1, the first roller 13 can lift the profile to prevent the profile from abutting against the clamping base plate 21.

[0039] Reference Figure 8 and 9 A sawing machine comprises a machine table 6, a sawing mechanism 7 is arranged at the end of the machine table 6, a fourth slide rail 81 and a power mechanism 82 are arranged horizontally along the front-back direction at the other end of the machine table 6, a moving seat 1 is slidably connected to the fourth slide rail 81, and the power mechanism 82 is used to drive the moving seat 1 to move;

[0040] The sawing mechanism 7 is a prior art disclosed in the patent publication number CN217452337U, and the power mechanism 82 is a ball screw.

[0041] In a preferred embodiment, in order to make the profile move more smoothly, a plurality of second rollers 91 are provided on the machine table 6 , and the second rollers 91 are located between the sawing mechanism 7 and the moving seat 1 .

[0042] In a preferred embodiment, in order to prevent the movable seat 1 from being blocked by the second roller 91 during the movement, a second cylinder 92 is provided on the machine table 6, and the second cylinder 92 is used to drive the second roller 91 to move up and down;

[0043] When the second cylinder 92 drives the second roller 91 to move downward a certain distance, the second roller 91 is located below the moving base 1 , and at this time, the second roller 91 avoids the moving base 1 .

[0044] When in use, the moving seat 1 is driven by the power mechanism 82 to move from the front end of the profile to the rear end thereof. During the movement, the first roller 13 is in rolling connection with the bottom surface of the profile. The moving seat 1 stops when it moves a certain distance. The first cylinder 22 drives the clamping bottom plate 21 to move upward and the third drive motor 52 drives the second clamping arm 53 to move downward, thereby clamping the profile in the vertical direction. The first drive motor 32 drives the clamping side plate 33 and the second drive motor 42 drives the first clamping arm 43 to move toward the profile and clamp the profile in the horizontal direction.

[0045] The moving seat 1 is driven by the power mechanism 82 to move toward the sawing mechanism 7. During the movement, the bottom surface of the profile is in rolling connection with the bottom surface of the second roller 91. When the moving seat 1 moves to the side of the second roller 91, the second cylinder 92 drives the second roller 91 to move downward to avoid the moving seat 1. At this time, the moving seat 1 can pass over the second roller 91, and then the second roller 91 will reset.

[0046] When the profile moves to the sawing mechanism 7, the moving seat 1 will stop moving, the sawing mechanism 7 will clamp the profile and process the profile. After processing the profile, the first cylinder 22 drives the clamping base plate 21 to move upward and the third drive motor 52 drives the second clamping arm 53 to release the profile in the vertical direction. The first drive motor 32 drives the clamping side plate 33 and the second drive motor 42 drives the first clamping arm 43 to release the profile in the horizontal direction. The power mechanism 82 drives the moving seat 1 to move toward the rear end of the profile and repeatedly clamps the profile. At this time, the sawing mechanism 7 will release the profile, allowing the moving seat 1 to push the profile, thereby repeatedly pushing the profile.

All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
