[0001] This utility model belongs to the field of CNC sawing technology, specifically relating to an assembly bed support structure for CNC sawing. Background Technology

[0002] A band saw is a machine tool that uses circular saw blades, band saws, or saw blades as cutting tools to cut round, square, pipe, and profile metal materials. The machining accuracy of band saws is generally not very high. They are mostly used in material preparation workshops to cut various bars, pipes, and other profiles. The saw blade is driven by a drive wheel and a driven wheel. The cutting direction of the saw blade is controlled by a guide rail control frame. Band saws are equipped with manual or hydraulic cylinder clamping and locking mechanisms, as well as hydraulic operating valves and switches.

[0003] Although existing CNC sawing machines are equipped with casters for movement, they are generally fixed and cannot be folded up when not in use, which can easily affect their service life. Furthermore, existing CNC sawing machines cannot balance the stability of the support and the adjustability of the position, resulting in poor applicability. Therefore, we propose an assembly bed support structure for CNC sawing machines. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an assembly bed support structure for CNC sawing machines, so as to solve the problems mentioned in the background art that although existing CNC sawing machines are equipped with casters for movement, they are generally fixed and cannot be folded up when not in use, which can easily affect the service life. In addition, existing CNC sawing machines cannot take into account both the stability of the support and the adjustability of the position, resulting in poor applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bed support structure for a CNC sawing machine, comprising a sawing machine body, a fixing plate 1 fixedly connected to the bottom of the front and rear ends of the sawing machine body, two sets of electric telescopic rods fixedly connected to the surface of the fixing plate 1, a push plate fixedly connected to the output end of the electric telescopic rods, a fixing plate 2 fixedly connected to the bottom of both sides of the sawing machine body, two sets of adjusting screws rotatably connected inside the fixing plate 2, a support foot fixedly connected to the bottom of the adjusting screws, and four sets of storage slots symmetrically opened on both sides of the sawing machine body, the interior of the storage slots... The saw body is equipped with a rotating structure, which includes a rotating rod. A caster wheel is mounted on the bottom of the rotating rod. A fixed rod is fixedly connected inside the rotating rod. Limiting blocks are fixedly connected to the front and rear ends of the fixed rod. Slots are formed on the surface of a set of limiting blocks. Limiting grooves are formed on the inner walls of the front and rear ends of the storage slot. A locking structure is provided at the four corners of the bottom of the saw body. The locking structure includes a sliding groove. A slider is slidably connected inside the sliding groove. A plug is fixedly connected to one end of the slider. Four sets of springs are fixedly connected to the other end of the slider. A pull rod is fixedly connected to the other end of the slider.

[0006] Preferably, the electric telescopic rod is electrically connected to the saw body, and the saw body is electrically connected to an external power source.

[0007] Preferably, the surface of the fixing plate is provided with a threaded groove, the adjusting screw is rotatably connected in the threaded groove, and the bottom of the push plate and the support foot is provided with a rubber pad layer.

[0008] Preferably, the limiting block is rotatably connected within the limiting groove, and both ends of the fixing rod penetrate the inner wall of the storage groove and are fixedly connected to the limiting block. The radius of the limiting block is larger than the radius of the fixing rod, and the rotating rod and the universal wheel are rotatable structures within the storage groove.

[0009] Preferably, the cross-section of the slider is larger than that of the insert block, the surface of the slider is in contact with the inner wall of the groove, and the pull rod passes through one side of the inner wall of the groove and is fixedly connected to the slider.

[0010] Preferably, the two ends of the spring are fixedly connected to the surface of the slider and the inner wall of the groove, respectively, and the center of the four sets of springs and the slider is arranged in a circle.

[0011] Preferably, the slide groove and the limiting groove are on the same axis, the cross-section of the insert is square, and the insert passes through the inner wall of one side of the slide groove and is inserted into the slot.

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

[0013] 1. This assembly bed support structure for a CNC sawing machine features a rotating structure and a locking structure. When the casters need to be retracted, pulling the lever causes the slider to slide within the groove, moving the insert block from the slot into the groove and compressing the spring. The insert block and slot are no longer locked together, allowing the casters to rotate around the fixed rod within the storage groove, thus retracting the casters. After rotating 90 degrees, releasing the lever causes the slider to move under the spring's action, re-inserting the insert block into the slot. The slot and insert block then lock together, fixing the angle of the adjusted casters and retracting them into the storage groove. When not in use, the casters can be stored in the storage groove, preventing them from being exposed for extended periods and increasing their lifespan.

[0014] 2. This assembly bed support structure for a CNC sawing machine is equipped with an electric telescopic rod, a push plate, adjusting screws, support feet, and casters. The casters allow direct movement of the sawing machine body. After moving to a suitable position, the electric telescopic rod drives the push plate downwards, lifting the sawing machine body after it contacts the ground. At this point, the casters can be retracted into the storage slot through the cooperation of the rotating and locking mechanisms. Rotating the adjusting screws on both sides engages with the threaded grooves, causing the support feet to contact the ground. With the push plate and support feet working together, the sawing machine body is stably placed on the ground. This design balances support stability and position adjustability, making it highly versatile. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A bed support structure for a CNC sawing machine includes a sawing machine body 1. Fixed plates 11 are fixedly connected to the bottom of the front and rear ends of the sawing machine body 1. Two sets of electric telescopic rods 12 are fixedly connected to the surface of the fixed plates 11. Push plates 13 are fixedly connected to the output ends of the electric telescopic rods 12. Fixed plates 24 are fixedly connected to the bottom of both sides of the sawing machine body 1. Two sets of adjusting screws 15 are rotatably connected inside the fixed plates 24. Support feet 16 are fixedly connected to the bottom of the adjusting screws 15. Four sets of storage slots 17 are symmetrically opened on both sides of the sawing machine body 1. A rotating structure 2 is provided inside the storage slots 17. The rotating structure 2 includes a rotating rod 21. A caster wheel 22 is installed at the bottom of the rotating rod 21. A fixed rod 23 is fixedly connected internally to the 21. Limiting blocks 24 are fixedly connected to the front and rear ends of the fixed rod 23. Slots 25 are opened on the surface of a set of limiting blocks 24. Limiting grooves 26 are opened on the inner walls of the front and rear ends of the storage groove 17. A locking structure 3 is provided at the four corners of the bottom of the saw body 1. The locking structure 3 includes a slide groove 31. A slider 32 is slidably connected inside the slide groove 31. An insert block 33 is fixedly connected to one end of the slider 32. Four sets of springs 34 are fixedly connected to the other end of the slider 32. A pull rod 35 is fixedly connected to the other end of the slider 32. A rotating structure 2 and a locking structure 3 are provided. When the caster wheel 22 needs to be retracted, the pull rod 35 is pulled to drive the slider 32 to slide in the slide groove 31, so that the insert block 33 moves from slot 25 into slide 31, compressing spring 34. The insert block 33 and slot 25 are no longer engaged, allowing caster wheel 22 to rotate around fixed rod 23 within storage slot 17 via rotating rod 21. This allows caster wheel 22 to be rotated and stored within storage slot 17. After rotating 90 degrees, pull rod 35 is released, and spring 34 pushes slider 32 to move, causing insert block 33 to re-insert into slot 25. Slot 25 and insert block 33 then engage, fixing the angle of caster wheel 22 after adjustment. Caster wheel 22 is then stored within storage slot 17. When not in use, caster wheel 22 can be stored within storage slot 17, preventing it from being exposed for extended periods and increasing the risk of injury. The universal wheel 22 is designed to extend the service life of the machine. It is equipped with an electric telescopic rod 12, a push plate 13, an adjusting screw 15, a support foot 16, and a universal wheel 22. The universal wheel 22 allows the saw body 1 to be moved directly. After being moved to a suitable position, the electric telescopic rod 12 drives the push plate 13 to move down, so that the push plate 13 contacts the ground and lifts the saw body 1. At this time, the universal wheel 22 can be put into the storage slot 17 through the cooperation of the rotating structure 2 and the locking structure 3. Rotating the adjusting screws 15 on both sides, in cooperation with the threaded groove, drives the support foot 16 to contact the ground. The push plate 13 and the support foot 16 cooperate to place the saw body 1 stably on the ground. It can take into account both the stability of the support and the adjustability of the position, and has good applicability.

[0024] Furthermore, the electric telescopic rod 12 is electrically connected to the saw body 1, and the saw body 1 is electrically connected to an external power source. The control system of the saw body 1 includes switches or program logic for controlling the movement of each electric telescopic rod 12. This is prior art and will not be described in detail hereafter. The operator can selectively extend or shorten the electric telescopic rod 12 through the control panel, thereby controlling the lifting and lowering movement of the push plate 13.

[0025] Furthermore, the surface of the fixing plate 14 is provided with a threaded groove, and the adjusting screw 15 is rotatably connected in the threaded groove. By manually turning the head of the adjusting screw 15, the adjusting screw 15 can move axially under the guidance and constraint of the threaded groove, thereby driving the support foot 16 to rise and fall. The bottom of the push plate 13 and the support foot 16 are provided with a rubber pad layer. By utilizing the elastic deformation ability and high friction coefficient of the rubber material, it plays a role in anti-slip, shock absorption and ground protection.

[0026] Furthermore, the limiting block 24 is rotatably connected within the limiting groove 26. The two ends of the fixing rod 23 penetrate the inner wall of the storage groove 17 and are fixedly connected to the limiting block 24. The radius of the limiting block 24 is larger than the radius of the fixing rod 23. The rotating rod 21 and the universal wheel 22 are rotatable structures within the storage groove 17. The limiting block 24 can rotate smoothly within the limiting groove 26. However, because its radius is larger than that of the fixing rod 23, and the limiting groove 26 provides axial constraint to the limiting block 24, the fixing rod 23 and the rotating rod 21 and universal wheel 22 rigidly connected to it are restricted as a whole within the storage groove 17. They can only rotate and will not axially move or fall off.

[0027] Furthermore, the cross-section of the slider 32 is larger than that of the insert block 33, and the surface of the slider 32 is in contact with the inner wall of the slide groove 31. This ensures the stability of the slider 32 when it moves in the slide groove 31 and prevents it from tilting or getting stuck. The pull rod 35 passes through one side of the inner wall of the slide groove 31 and is fixedly connected to the slider 32. The pull rod 35 serves as an operating handle and is fixedly connected to the slider 32, directly transmitting the pushing and pulling force to the slider 32.

[0028] Furthermore, the two ends of the spring 34 are fixedly connected to the surface of the slider 32 and the inner wall of the groove 31, respectively. The four sets of springs 34 are arranged in a circle with the center of the slider 32. When the slider 32 is pulled by the pull rod 35, all the springs 34 are compressed synchronously to generate a uniform restoring force. When the pull rod 35 is released, the restoring force pushes the slider 32 back to its original position, ensuring that the insert block 33 can be accurately inserted into the slot 25.

[0029] Furthermore, the slide 31 and the limiting groove 26 are on the same axis. The cross-section of the insert 33 is square. The insert 33 passes through the inner wall of one side of the slide 31 and is inserted into the slot 25. The outlet of the slide 31 is directly opposite the limiting block 24 in the limiting groove 26. When the rotating rod 21 rotates to a specific angle, the slot 25 on the limiting block 24 will be aligned with the outlet of the slide 31. After the square-section insert 33 is inserted into the slot 25 with the matching shape, it can effectively prevent the limiting block 24 from rotating, thereby achieving reliable locking of the entire rotating structure 2.

[0030] Working principle: The electric telescopic rod 12 drives the push plate 13 to move downwards, so that the push plate 13 contacts the ground and lifts the saw body 1. At this time, the universal wheels 22 can be put into the storage groove 17 through the cooperation of the rotating structure 2 and the locking structure 3. Rotating the adjusting screws 15 on both sides, in cooperation with the threaded groove, drives the support feet 16 to contact the ground. The push plate 13 and the support feet 16 cooperate to place the saw body 1 stably on the ground. When the equipment needs to be moved, the operator first pulls the four pull rods 35 outwards at the same time. The pull rods 35 drive the slider 32 to slide in the slide groove 31 and compress the spring. Spring 34 causes the insert 33 to disengage from the slot 25 of the limiting block 24. Manually rotate the rotating rod 21 (along with the caster 22) from the horizontal storage state to the vertical downward use state. Release the pull rod 35, and the compressed spring 34 pushes the slider 32 back to its original position, causing the insert 33 to insert into the corresponding slot 25 on the current limiting block 24, locking the caster 22 in the use position. Rotate the adjusting screw 15 in the opposite direction to raise the support foot 16 and drive the push plate 13 upward through the electric telescopic rod 12, so that the caster 22 contacts the ground, thereby allowing the equipment to be moved.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
