Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically a cutting machine feeding and positioning device. Background Technology

[0002] A saw blade cutting machine is a common and powerful cutting machine that can cut common materials such as metal square and flat tubes, square and flat steel, I-beams, channel steel, carbon steel, and tubes. When a small number of workpieces need to be cut on site, using a saw blade cutting machine is undoubtedly the most convenient and effective method.

[0003] A search revealed a patent application with publication number CN113618930A that discloses a cutting machine, comprising: a machine body having a gripping part; a motor housed within the machine body and including a motor shaft; and a saw blade assembly connected to the machine body. The saw blade assembly includes a protective cover and an output shaft, the output shaft being driven by the motor shaft and used to mount the saw blade. The machine body is rotatable relative to the saw blade assembly around the output shaft, allowing the cutting machine to have a first working state and a second working state. This cutting machine, when performing planar cutting, is capable of cutting corners in both directions.

[0004] A patent application with publication number CN118386285A discloses a cutting machine, including a fixed base, a cutting assembly, a rotating assembly, a first clamping block, and a second clamping block. The first and second clamping blocks are correspondingly disposed on the fixed base. The cutting assembly is used to cut the object to be cut and is movably disposed on the fixed base between a cutting position and a disengaged position. In the cutting position, the cutting assembly cooperates with each of the first and second clamping blocks to cut the object; in the disengaged position, the cutting assembly is away from the first and second clamping blocks. The rotating assembly is rotatably disposed on the fixed base and is connected to both the cutting assembly and the first clamping block. When the cutting assembly moves from the cutting position to the disengaged position, the first clamping block moves away from the second clamping block; when the cutting assembly moves from the disengaged position to the cutting position, the cutting assembly, through the rotating assembly, drives the first clamping block closer to the second clamping block. This cutting machine can fix the object to be cut during cutting, reducing safety hazards during use.

[0005] A patent application with publication number CN107042462A discloses a cutting machine, including: a base, a cutting head, a baffle, and a mounting base; the base forms a support surface for placing a workpiece; the cutting head is rotatably connected to the base and includes a cutting element, a motor, a housing, and a protective cover; the cutting element is used to cut the workpiece placed on the support surface; the motor is used to drive the cutting element to rotate about an axis; the housing is used to house the motor; the protective cover is used to stop workpiece debris on the side operated by the user; the baffle is used to stop workpiece debris on the opposite side operated by the user; the mounting base is used to replaceably mount the baffle; wherein, the protective cover is movably connected to the housing; the mounting base is connected to the base; this cutting machine has good chip-blocking effect, long service life, and low cost.

[0006] Although the existing cutting machines mentioned above can cut workpieces, in actual use, different products often require cut parts of specific sizes. This requires the cutting machine to be able to flexibly and accurately meet various size requirements. The traditional approach is to first use manual measuring tools such as measuring tapes, rulers, and vernier calipers to draw lines on the workpiece before cutting. This not only results in large errors and low efficiency, but also affects product quality and production progress.

[0007] Therefore, a cutting machine feeding and positioning device is proposed to address the above problems. Utility Model Content

[0035] 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 scope of protection of the present utility model.

[0036] like Figures 1 to 4 As shown, a cutting machine unloading and positioning device includes a base plate 1; a cutting machine 2 is disposed on the top surface of the base plate 1; the cutting machine 2 is used to cut a workpiece 3; a positioning structure is disposed on one side of the base plate 1, and the positioning structure is used to limit the cutting length of the workpiece 3; the positioning structure includes a fixed seat 4 fixedly connected to the side of the base plate 1; a guide square tube 5 is fixedly connected to the side of the fixed seat 4 away from the base plate 1; a positioning baffle 6 is slidably installed on the top surface of the guide square tube 5; a locking assembly is disposed on the bottom surface of the positioning baffle 6, and the locking assembly is used to lock the positioning baffle 6 and the guide square tube 5.

[0037] Before cutting workpiece 3, a measuring tape is used to measure the required length of workpiece 3 on the guide square tube 5, which is the distance between the cutting position of the blade of the cutting machine 2 and the positioning position on the guide square tube 5. Then, the positioning baffle 6 is moved along the guide square tube 5 to the measured fixed position, and the positioning baffle 6 is locked and fixed using the locking assembly. At this time, the distance between the positioning baffle 6 and the cutting position of the blade of the cutting machine 2 is the cutting length of workpiece 3.

[0038] After the position of the positioning baffle 6 is adjusted, the workpiece 3 is placed on the bottom plate 1, and one end of the workpiece 3 contacts the positioning baffle 6 along the guide square tube 5. The cutting machine 2 is then pressed down, so that the blade of the cutting machine 2 cuts the workpiece 3. When workpieces 3 of the same size are needed, the position of the positioning baffle 6 only needs to be adjusted once, so that the cut workpieces 3 can be guaranteed to have uniform size, which improves cutting accuracy and efficiency, and ensures product quality and production progress.

[0039] like Figures 2 to 7 As shown, the locking assembly includes a locking slider 7; the bottom surface of the positioning baffle 6, away from the base plate 1, is evenly provided with multiple fixing grooves 8; the locking slider 7 is bolted into one of the middle fixing grooves 8; the top surface of the guide square tube 5 is provided with a locking slide groove 9; the locking slider 7 is slidably engaged with the locking slide groove 9; the locking slider 7 has an inner cavity 10 inside; the two sides of the inner cavity 10 extend through the two sides of the locking slider 7; a push block 11 is slidably installed in the middle of the inner cavity 10; the top of the push block 11 rotates... A locking screw 12 is movably installed; the locking screw 12 passes through the top surface of the locking slider 7 and is threadedly engaged with the locking slider 7; pressing blocks 13 are slidably installed on both sides of the bottom of the inner cavity 10; a mounting base 14 is fixedly connected to the side of the pressing block 13 near the push block 11; a rotating roller 15 is rotatably installed in the middle of the mounting base 14; the rotating roller 15 is slidably engaged with the bottom inclined surface of the push block 11; a plurality of No. 1 springs 16 are fixedly connected between the bottom side of the pressing block 13 near the middle of the inner cavity 10 and the middle of the inner cavity 10.

[0040] In the initial state, the locking screw 12 drives the push block 11 to be located at the top of the inner cavity 10 of the locking slider 7. At this time, the inclined surfaces on both sides of the bottom of the push block 11 do not squeeze the rotating roller 15, so that the first spring 16 pushes the pressing seat 13 to be housed in the inner cavity 10, so that the locking slider 7 can slide along the locking groove 9.

[0041] During locking, the positioning baffle 6 drives the locking slider 7 to move along the locking groove 9 of the guide square tube 5 to the measured fixed position. Then, the operator rotates the locking screw 12. Due to the threaded engagement between the locking screw 12 and the top of the locking slider 7, the locking screw 12 moves towards the interior of the inner cavity 10, pushing the push block 11 to slide downward along the inner cavity 10. The inclined surfaces on both sides of the bottom of the push block 11 press the rotating rollers 15 on both sides, causing the rotating rollers 15 to rotate and reduce friction. The rotating rollers 15 push the mounting base 14 and the pressing block 13 to slide towards the outside of the locking slider 7, causing the pressing block 13 to slide out from the inner cavity 10 and press the side wall of the locking groove 9. The pressing blocks 13 on both sides simultaneously press the sides of the locking groove 9, locking the locking slider 7 in the locking groove 9, and thus fixing the positioning baffle 6 to the top of the guide square tube 5. This allows the operator to flexibly adjust the position of the positioning baffle 6, thereby facilitating the control and adjustment of the cutting length of the workpiece 3.

[0042] like Figures 6 to 7 As shown, the bottom of the push block 11 is an inverted trapezoidal block, and the top is a cross-shaped column; the bottom two sides of the inner cavity 10 are provided with limiting grooves 17; the two sides of the extrusion block 13 are provided with inserts 18; the inserts 18 are slidably engaged with the limiting grooves 17.

[0043] By setting the bottom of the push block 11 as a trapezoidal block, the two sides of the bottom of the push block 11 are symmetrical inclined surfaces, which can simultaneously push the two rotating rollers 15 to move, so that the two pressing blocks 13 can simultaneously contact the inner walls of the two sides of the pressing locking groove 9, thereby improving the locking stability of the locking slider 7; by setting the top of the push block 11 as a cross-shaped column, the push block 11 can be limited and guided by the inner cavity 10, so that the push block 11 can only slide up and down, thereby improving the accuracy and stability of the movement of the push block 11.

[0044] By slidingly engaging the insert 18 on the extrusion block 13 with the limiting groove 17 on the side wall of the inner cavity 10, not only is the extrusion block 13 prevented from detaching from the inner cavity 10, but the stability of the movement of the extrusion block 13 is also improved.

[0045] like Figure 2 , Figure 3 and Figure 8 As shown, guide sliders 19 are bolted into the two fixing grooves 8 on both sides; guide grooves 20 are provided on both sides of the top surface of the guide square tube 5; the guide sliders 19 and the guide grooves 20 are slidably engaged.

[0046] The guide slider 19 slides with the guide groove 20 to guide the movement of the positioning baffle 6; and after the positioning baffle 6 is fixed, since the guide slider 19 is located in the guide groove 20, it is difficult for the positioning baffle 6 to deflect when it is pressed and contacted by the workpiece 3.

[0047] like Figure 9 and Figure 10 As shown, a square fixing protrusion ring 21 is fixedly connected to one end of the guide square tube 5; a first locking groove 22 is opened on both sides of the fixing protrusion ring 21; a U-shaped retaining strip 23 is fixedly connected to the inner wall of the fixing protrusion ring 21 and to the outer periphery of the first locking groove 22; a square fixing inner groove 24 is opened on the inner side of the other end of the guide square tube 5 and the inner side of the fixing seat 4; the fixing protrusion ring 21 matches the fixing inner groove 24; a second locking groove 25 is opened on both sides of the fixing inner groove 24; the second locking groove 25 matches the first locking groove 22; a plurality of square nuts 26 are slidably installed inside the U-shaped retaining strip 23; a fastening screw 27 is threaded in the middle of the square nut 26; the fastening screw 27 can pass through the first locking groove 22 and the second locking groove 25;

[0048] Since the lengths of workpieces 3 vary, and fixed-length guide square tubes 5 are difficult to adapt to longer workpieces 3, a suitable number of guide square tubes 5 are selected according to the different lengths of the workpieces, and multiple guide square tubes 5 are connected in series end to end.

[0049] Slide the square nut 26 into the U-shaped slot 23, insert the fixing protrusion 21 at the end of one guide square tube 5 into the fixing inner groove 24 at the end of another guide square tube 5, so that the first locking groove 22 corresponds to the second locking groove 25. Use the locking screw 27 to pass through the first locking groove 22 and the second locking groove 25, and then cooperate with the square nut 26 to lock, so that the two guide square tubes 5 are connected end to end; thus facilitating the cutting of workpieces 3 of different lengths.

[0050] like Figures 2 to 4 As shown, a vertical groove 28 is provided in the middle of the positioning baffle 6; a plurality of sliding rods 29 are fixedly connected between the top and bottom surfaces of the vertical groove 28; a pressure plate 30 is slidably installed near the inside of the vertical groove 28; the pressure plate 30 faces the side of the cutting machine 2; the sliding rods 29 slide through the pressure plate 30; a second spring 31 is sleeved on the outer ring of the middle sliding rod 29; the second spring 31 is located at the top of the pressure plate 30; the bottom surface of the pressure plate 30 can press the top surface of the end of the workpiece 3;

[0051] When the workpiece 3 needs to be cut during operation, one end of the workpiece 3 contacts the positioning baffle 6 along the guide square tube 5. At this time, the second spring 31 pushes the pressure plate 30 to slide down along the slide groove 29, so that the pressure plate 30 presses down on the end of the workpiece 3. Together with the guide square tube 5, the end of the workpiece 3 is clamped and fixed, so that when the cutting machine 2 cuts the workpiece 3 downward, the end of the workpiece 3 is prevented from lifting up, thus improving the cutting accuracy of the workpiece 3.

[0052] like Figures 2 to 4As shown, positioning pointers 32 are bolted to both sides of the bottom of the positioning baffle 6; the side of the positioning pointer 32 coincides with the side of the positioning baffle 6 near the cutting machine 2; the positioning pointer 32 is located on the side of the guide square tube 5.

[0053] When working, when measuring the required length of workpiece 3 on the guide square tube 5 with a tape measure, you can draw the positioning point of the commonly used workpiece 3 length on the side of the guide square tube 5; you can also draw the scale line on the side of the guide square tube 5; by moving the positioning pointer 32 along the side of the guide square tube 5, in conjunction with the sliding positioning point or scale line, you can quickly and accurately adjust the cutting length of workpiece 3.

[0054] like Figures 1 to 3 As shown, multiple internally threaded blocks 33 are fixedly connected to both sides of the guide square tube 5; a lifting screw 34 is threadedly installed in the middle of the internally threaded block 33; and a foot block 35 is rotatably installed at the bottom end of the lifting screw 34.

[0055] During operation, rotating the lifting screw 34, in conjunction with the internal thread block 33, pushes the foot block 35 downward, causing the foot block 35 to contact the ground and support the guide square tube 5. Adjusting the height of the guide square tube 5 allows the workpiece 3 to remain horizontal during cutting. Furthermore, by adjusting the height using multiple lifting screws 34, the guide square tube 5 can remain horizontal even on uneven bottom surfaces, thereby effectively improving the cutting quality of the workpiece 3.

[0056] like Figure 1 and Figure 11 As shown, a strip 36 is fixedly connected to the top surface of the base plate 1 near the fixed seat 4; a plurality of positioning grooves 37 are evenly opened on the top surface of the strip 36; a pair of clamping plates 38 are provided on the top surface of the strip 36; a plurality of positioning blocks 39 are fixedly connected to the bottom surface of the clamping plates 38; the positioning blocks 39 can be inserted into the positioning grooves 37; the two clamping plates 38 are located on both sides of the workpiece 3.

[0057] Based on the width of workpiece 3, the distance between the two clamping plates 38 is controlled, and the two clamping plates 38 are installed on the top surface of the strip 36, so that the positioning block 39 is inserted into the positioning groove 37, and the two clamping plates 38 are clamped on both sides of workpiece 3. When cutting workpiece 3, the clamping plates 38 on both sides limit workpiece 3, thereby preventing workpiece 3 from shifting during cutting and improving the cutting quality of workpiece 3.

[0058] like Figure 1As shown, a plurality of cutting slots 40 are evenly provided in the middle of the base plate 1; the cutting blade of the cutting machine 2 is matched with the cutting slots 40; through the cutting slots 40, the cutting blade of the cutting machine 2 cuts the workpiece 3 and enters the cutting slot 40, thereby ensuring that the workpiece 3 can be cut off, while avoiding damage to the cutting blade of the cutting machine 2.

[0059] Working principle: Select an appropriate number of guide square tubes 5 according to the different lengths of the workpiece, and connect multiple guide square tubes 5 end to end in series; slide the square nut 26 into the U-shaped groove 23, insert the fixing protrusion 21 at the end of one guide square tube 5 into the fixing inner groove 24 at the end of another guide square tube 5, so that the first locking groove 22 corresponds to the second locking groove 25, use the locking screw 27 to pass through the first locking groove 22 and the second locking groove 25, and then cooperate with the square nut 26 to lock, so that the two guide square tubes 5 are connected end to end in series and fixed.

[0060] Rotate the lifting screw 34, which, in conjunction with the internal thread block 33, push the foot block 35 downward so that the foot block 35 contacts the ground, supporting the guide square tube 5, adjusting the height of the guide square tube 5, and adjusting the height through multiple lifting screws 34 so that the guide square tube 5 can remain level even on uneven bottom surfaces.

[0061] Use a measuring tape to measure the required length of the workpiece 3 on the guide square tube 5, that is, the distance between the cutting position of the blade of the cutting machine 2 and the positioning position on the guide square tube 5. The positioning point for the commonly used length of the workpiece 3 can be drawn on the side of the guide square tube 5; or a scale line can be drawn on the side of the guide square tube 5. By moving the positioning pointer 32 along the side of the guide square tube 5, in conjunction with the sliding positioning point or scale line, the cutting length of the workpiece 3 can be adjusted quickly and accurately.

[0062] After the positioning baffle 6 moves the locking slider 7 along the locking groove 9 of the guide square tube 5 to the measurement point, the operator rotates the locking screw 12. Due to the threaded engagement between the locking screw 12 and the top of the locking slider 7, the locking screw 12 moves towards the interior of the inner cavity 10, pushing the push block 11 to slide downwards along the inner cavity 10. The inclined surfaces on both sides of the bottom of the push block 11 press the rotating rollers 15 on both sides, causing the rotating rollers 15 to rotate and reduce friction. The rotating rollers 15 push the mounting base 14 and the pressing block 13 to slide towards the outside of the locking slider 7, causing the pressing block 13 to slide out from the inner cavity 10 and press the side wall of the locking groove 9. The pressing blocks 13 on both sides simultaneously press the sides of the locking groove 9, locking the locking slider 7 in the locking groove 9, and thus fixing the positioning baffle 6 to the top of the guide square tube 5.

[0063] The workpiece 3 is placed on the bottom plate 1, and one end of the workpiece 3 contacts the positioning baffle 6 along the guide square tube 5. At the same time, the second spring 31 pushes the pressure plate 30 to slide down along the slide groove 29, so that the pressure plate 30 presses down on the end of the workpiece 3. In conjunction with the guide square tube 5, the end of the workpiece 3 is clamped and fixed. The two clamping plates 38 are clamped on both sides of the workpiece 3.

[0064] The downward cutting machine 2 causes the blade of the cutting machine 2 to cut the workpiece 3; whenever the same size workpiece 3 is needed, the position of the positioning baffle 6 only needs to be adjusted once, so that the cut workpiece 3 can be guaranteed to have a uniform size, improving cutting accuracy and efficiency, and ensuring product quality and production progress.
