Because sawing has the advantages of fast cutting speed, convenient operation and high production efficiency, the sawing machine is widely used in the steel, section steel and plate processing industries as an important part processing equipment.

[0003] When a sawing machine is cutting, the workpiece needs to be clamped and fixed to ensure its stability during cutting. In the existing technology, the workpiece is clamped and fixed by manually rotating the screw turntable and the screw transmission structure. However, when the workpiece needs to be cut in multiple places, it is necessary to repeatedly unlock and lock the workpiece, which is cumbersome. Therefore, it is necessary to design a clamping device for sawing machine cutting to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a clamping device for sawing, comprising:

[0007] A saw base, on which a clamping mechanism is provided;

[0008] The clamping mechanism includes a clamping frame, a rotating shaft, a rotating cylinder, a rod body one, a disc one, an anti-slip pad one, a spring, a rod body two, a disc two, an anti-slip pad two, a top plate, a hydraulic cylinder, a push plate, and a sleeve plate;

[0009] The rotating shaft is rotatably mounted on the clamping frame and fixedly connected to the rotating cylinder. The first disc is fixedly connected to the first rod and the first anti-slip pad. The spring is fixedly installed between the first disc and the rotating cylinder. The second disc is fixedly connected to the second rod and the second anti-slip pad. The bottom of the top plate is fixedly connected to the second rod. The hydraulic rod of the hydraulic cylinder is fixedly connected to the push plate. The sleeve is fixedly installed on the top of one top plate and slides on the outside of the push plate. The top of the other top plate is fixedly connected to the push plate.

[0010] A further feature of this invention is that the clamping mechanism includes a frame, a threaded cylinder, and a screw. There are two clamping frames, one of which is fixedly connected to the bottom of the saw base, and the threaded cylinder is fixedly installed on the other clamping frame. The frame is fixedly installed on the top of the saw base, the screw is rotatably installed on the frame, and the hydraulic cylinder is fixedly installed on the top of the frame. The screw is threadedly connected to the threaded cylinder.

[0011] A further feature of this invention is that two sliding rods are slidably mounted on the frame, and the sliding rods are fixedly connected to the clamping frame.

[0012] By adopting the above technical solution, the right clamping frame can move stably.

[0013] A further feature of this invention is that both the disc and the anti-slip pad are slidably fitted onto the outer side of the lower rotating shaft, with the bottom of the anti-slip pad abutting against the clamping frame.

[0014] A further feature of this invention is that the first rod is vertically slidably mounted on the rotating drum, and the top of the first rod is in contact with the second anti-slip pad.

[0015] By adopting the above technical solution, the anti-slip pad 2 can push the rod down when it moves downward.

[0016] A further feature of this invention is that both the second disc and the second anti-slip pad are slidably sleeved on the outside of the upper rotating shaft, with the bottom of the second anti-slip pad abutting against the rotating cylinder.

[0017] By adopting the above technical solution, the rotating drum can be subjected to contact and limiting treatment.

[0018] A further feature of this invention is that the two rods are vertically slidably mounted on the clamping frame.

[0019] A further feature of this invention is that the workpiece to be processed is placed on the top of the saw base.

[0020] A further feature of this invention is that a pushing assembly is provided on the top of the saw base, the pushing assembly including an auxiliary hydraulic cylinder and a pushing component, the hydraulic rod of the auxiliary hydraulic cylinder being fixedly connected to the pushing component.

[0022] A further feature of this invention is that a cutting assembly is provided on the top of the saw base, the cutting assembly including an auxiliary hydraulic cylinder two and a cutting component, and the hydraulic rod of the auxiliary hydraulic cylinder two is fixedly connected to the cutting component.

[0023] The beneficial effects of this utility model are:

[0024] This invention utilizes a clamping mechanism. By rotating a screw, the workpiece is clamped and limited by two rotating cylinders on both sides. When the workpiece needs to be cut again after the initial cutting, the hydraulic cylinder is activated, causing the push plate to move upward. This allows the anti-slip pads one and two to move upward synchronously, releasing the limitation on the rotating cylinders. Then, the workpiece is pushed by the pushing component, and the hydraulic cylinder is activated again to lock and limit the rotating cylinders, thus limiting the workpiece. This eliminates the need for repeated clamping and unclamping of the workpiece via the screw drive structure, making the operation more convenient. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a clamping device for sawing, comprising:

[0034] The saw base 1 is equipped with a clamping mechanism. It should be noted that when cutting the workpiece in multiple places, it is not necessary to repeatedly clamp or unclamp the workpiece through the screw drive structure, making the operation more convenient.

[0035] The clamping mechanism includes a clamping frame 3, a rotating shaft 4, a rotating cylinder 5, a rod 6, a disc 7, an anti-slip pad 8, a spring 9, a rod 2 10, a disc 2 11, an anti-slip pad 2 12, a top plate 13, a hydraulic cylinder 14, a push plate 15, and a sleeve plate 16.

[0036] The rotating shaft 4 is rotatably mounted on the clamping frame 3. The rotating shaft 4 is fixedly connected to the rotating cylinder 5. It should be noted that there are multiple rotating cylinders 5 on each clamping frame 3. The rotating cylinders 5 are used to abut and limit the workpiece to be processed.

[0037] Disc 7 is fixedly connected to rod 6 and anti-slip pad 8. Spring 9 is fixedly installed between disc 7 and rotating cylinder 5. Disc 11 is fixedly connected to rod 10 and anti-slip pad 12. The bottom of top plate 13 is fixedly connected to rod 10. The hydraulic rod of hydraulic cylinder 14 is fixedly connected to push plate 15. Sleeve 16 is fixedly installed on the top of one top plate 13. Sleeve 16 is slidably sleeved on the outside of push plate 15. The top of the other top plate 13 is fixedly connected to push plate 15.

[0038] Through the aforementioned clamping mechanism, activating the hydraulic cylinder 14 causes the push plate 15 to move the sleeve plate 16 and the top plate 13 downwards. The top plate 13 then moves the rod 10 downwards, which in turn moves the disc 11 downwards. The disc 11 then moves the anti-slip pad 12 downwards, causing the anti-slip pad 12 to press against and limit the rotating cylinder 5. The anti-slip pad 12 also presses against the rod 6, causing it to move downwards. This, in turn, causes the disc 7 to move the anti-slip pad 8 downwards. The disc 7 then stretches the spring 9, causing the anti-slip pad 8 to come into contact with the inner wall of the clamping frame 3. This effectively supports the rotating cylinder 5. The limit switch ensures the stability of the multiple rotating drums 5 after clamping the workpiece. If the workpiece needs to be cut again after cutting, the push plate 15 moves upward to release the limit switch on the rotating drum 5. Then, the push assembly 18 pushes the workpiece to move, and the rotating drum 5 rotates. When it moves to the cutting position, the push plate 15 moves downward to lock the rotating drum 5, thus locking the workpiece. This eliminates the need to repeatedly clamp or release the workpiece through the screw drive structure, making the operation more convenient.

[0039] Specifically, the clamping mechanism also includes a frame 2, a threaded cylinder 17, and a screw 18. There are two clamping frames 3. The bottom of one clamping frame 3 is fixedly connected to the base of the sawing machine 1, and the threaded cylinder 17 is fixedly installed on the other clamping frame 3. The frame 2 is fixedly installed on the top of the base of the sawing machine 1. The screw 18 is rotatably installed on the frame 2. The hydraulic cylinder 14 is fixedly installed on the top of the frame 2. The screw 18 is threadedly connected to the threaded cylinder 17.

[0040] Through the aforementioned clamping mechanism, by rotating the screw 18, the threaded cylinder 17 can drive the clamping frame 3 on the right to move, thereby allowing the sleeve 16 to slide on the outside of the push plate 15.

[0041] Specifically, two sliding rods are horizontally slidably installed on the frame 2, and the sliding rods are fixedly connected to the clamping frame 3. The workpiece to be processed is placed on the top of the saw base 1. It should be noted that this allows the clamping frame 3 on the right to move stably.

[0042] Specifically, disc 7 and anti-slip pad 8 are slidably fitted on the outside of the lower rotating shaft 4. The bottom of anti-slip pad 8 abuts against the clamping frame 3. Rod 6 is vertically slidably mounted on the rotating cylinder 5. The top of rod 6 contacts anti-slip pad 12. Disc 11 and anti-slip pad 12 are slidably fitted on the outside of the upper rotating shaft 4. The bottom of anti-slip pad 12 abuts against the rotating cylinder 5. Rod 10 is vertically slidably mounted on the clamping frame 3. It should be noted that this arrangement facilitates the vertical movement of rod 6, disc 7, anti-slip pad 8, rod 10, disc 11, and anti-slip pad 12.

[0043] Specifically, a pushing assembly 19 is provided on the top of the saw base 1. The pushing assembly 19 includes an auxiliary hydraulic cylinder and a pushing component. The hydraulic rod of the auxiliary hydraulic cylinder is fixedly connected to the pushing component. It should be noted that the workpiece to be processed is pushed by the pushing assembly 19.

[0044] Specifically, a cutting assembly 20 is provided on the top of the saw base 1. The cutting assembly 20 includes an auxiliary hydraulic cylinder 2 and a cutting component. The hydraulic rod of the auxiliary hydraulic cylinder 2 is fixedly connected to the cutting component. It should be noted that the workpiece to be processed is cut by the cutting assembly 20.

[0045] Working principle:

[0046] S1: Rotate screw 18. Since screw 18 is threadedly connected to threaded cylinder 17 and threaded cylinder 17 is fixed on right clamping frame 3, rotating screw 18 will cause right clamping frame 3 to move laterally. As the distance between the two clamping frames 3 is adjusted, multiple rotating cylinders 5 gradually approach the workpiece to be processed until the rotating cylinders 5 contact the workpiece surface, completing the initial positioning and clamping of the workpiece. At this time, the rotating cylinders 5 can rotate freely under the support of rotating shaft 4, but are not yet completely locked.

[0047] S2: Start hydraulic cylinder 14, whose hydraulic rod pushes push plate 15 downward. Push plate 15 drives top plate 13 and sleeve plate 16 connected to it to move downward synchronously. Top plate 13 drives rod 10 to move downward. Rod 10 drives disc 11 and anti-slip pad 12 to move downward. Anti-slip pad 12 is in close contact with the top of rotating drum 5, restricting the rotation of rotating drum 5. At the same time, anti-slip pad 12 presses down rod 6. Rod 6 drives disc 7 and anti-slip pad 8 to slide downward. Disc 7 stretches spring 9. Anti-slip pad 8 finally abuts against the inner wall of clamping frame 3, forming a stable limit lock on rotating drum 5 from both the top and bottom, ensuring that the workpiece will not be displaced due to the rotation of rotating drum 5 during the cutting process.

[0048] S3: After the workpiece is firmly clamped, the auxiliary hydraulic cylinder 2 in the cutting assembly 20 pushes the cutting component to cut the workpiece. When one part of the workpiece is cut and the next part needs to be cut, the hydraulic cylinder 14 is started again. The hydraulic rod drives the push plate 15 to move upward. The push plate 15 drives the top plate 13 and the sleeve plate 16 to rise. The rod 2 10, the disc 2 11 and the anti-slip pad 2 12 move upward accordingly, releasing the limit on the rotating drum 5. At this time, the spring 9, due to the elastic force generated by the previous stretching, pulls the disc 1 7 and the anti-slip pad 1 8 upward, separating them from the inner wall of the clamping frame 3, and the rotating drum 5 returns to the free rotation state.

[0049] S4: Start the push assembly 19, and the hydraulic rod of the auxiliary hydraulic cylinder pushes the pusher to move the workpiece to the next cutting position. During the movement of the workpiece, the rotating drum 5 rotates with the movement of the workpiece to adapt to the displacement of the workpiece. When the workpiece reaches the appropriate cutting position, control the hydraulic cylinder 14 again to move the push plate 15 down, repeat the clamping and fixing steps, relock the rotating drum 5, and complete the re-limiting of the workpiece so as to carry out the next cutting operation.

[0050] Through the above working process, the clamping device avoids the cumbersome operation of clamping and fixing or releasing the workpiece multiple times using the screw drive structure in the traditional method. By controlling the up and down movement of the push plate 15 through the hydraulic cylinder 14, the rotating drum 5 can be quickly locked and unlocked, thereby quickly adjusting the position of the workpiece and significantly improving the efficiency of workpiece clamping and adjustment in the sawing operation.

[0051] The foregoing has provided a detailed description of a clamping device for sawing machines. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
