Description

Technical Field

[0001] This invention relates to the field of machine tool technology, specifically to a sawing machine tool for processing bar stock parts. Background Technology

[0002] Some furniture manufacturing processes require the use of metal rods, such as metal support columns (legs) for tables, chairs, and beds. These support legs are typically made of cylindrical metal rods. During production, these long rods often need to be cut to the required lengths, necessitating the use of cutting equipment. However, current cutting equipment generates significant amounts of dust during the cutting process, which is detrimental to worker health. Furthermore, cutting requires either electric or manual clamps to hold the rod in place before cutting. Electric clamps increase manufacturing costs, while manual clamps are cumbersome and inefficient. Therefore, we propose a sawing machine for processing rod fittings to address these issues.

[0022] like Figure 1 , Figure 7 , Figure 8 and Figure 9As shown, a water storage tank 11 and a mounting base 12 are fixed to the top of the base 1. The water storage tank 11 is filled with water, and a filter screen plate 15 is slidably installed inside the top of the water storage tank 11. L-shaped handles 16 are fixed to both ends of the filter screen plate 15, and the lower top surfaces of the two L-shaped handles 16 are attached to the top of the water storage tank 11. A water spraying assembly 13 for spraying water to reduce dust at the sawing part of the bar is provided on the mounting base 12. The water spraying assembly 13 includes a housing 1301 fixed to the top of the mounting base 12, and an impeller 1302 is provided inside the housing 1301. The middle of the impeller 1302 is fixed through the impeller. There is a rotating shaft 1303, one end of which is rotatably connected to the side wall of the housing 1301 via a bearing. The water inlet end of the housing 1301 is fixedly connected to a water pumping pipe 1304, one end of which extends into the interior of the water storage tank 11. The water outlet end of the housing 1301 is fixedly connected to a water supply pipe 1305, one end of which passes through the top of the support platform 3 and is fixedly connected to a nozzle 1306. The nozzle 1306 is located on one side of the sawing assembly 8. The top of the support platform 3 is fixed with a support block for supporting the water supply pipe 1305 in order to improve the stability of the water supply pipe 1305.

[0023] like Figure 1 , Figure 3 and Figure 5As shown, a strip-shaped opening for avoiding the sawing assembly 8 is provided on the top of the support platform 3 and inside the enclosure 9. The strip-shaped opening is located directly above the water storage tank 11. A drive assembly 14 for driving the sawing assembly 8 and the water spray assembly 13 is provided on the mounting base 12. The drive assembly 14 includes a second motor 1401 fixed to the top of the mounting base 12. A rotating rod 1402 is fixed to the output shaft of the second motor 1401. One end of the rotating rod 1402 is fixedly connected to one end of the rotating shaft 1303. A fixed surface is fitted on the surface of the rotating rod 1402. A first bevel gear 1403 is fixed, and a second bevel gear 1404 is meshed with the surface of the first bevel gear 1403. A cylinder 1405 is fixed to the middle of the second bevel gear 1404. The cylinder 1405 is rotatably connected to the support platform 3 via a bearing. An L-shaped stabilizing plate is fixed to the bottom of the support platform 3. The bottom end of the cylinder 1405 is rotatably connected to the L-shaped stabilizing plate via a bearing to make the cylinder 1405 more stable when rotating. Two retaining rings are fixedly fitted on the surface of the cylinder 1405. The two retaining rings are respectively fitted and set... The top and bottom of the support platform 3 are designed to ensure greater stability when the cylinder 1405 rotates relative to the support platform 3. A sliding rod 1406 is slidably mounted inside the cylinder 1405. Four limiting strips are fixed in a circumferential array on the surface of the sliding rod 1406. Four limiting grooves that fit the limiting strips are formed in a circumferential array on the inner wall of the cylinder 1405. This allows the sliding rod 1406 to move smoothly within the cylinder 1405, and when the cylinder 1405 rotates, it can smoothly drive the sliding rod 1406 to rotate. The top end of the rod 1406 is rotatably connected to the bottom of the frame 6 via a bearing. Two rings are fixedly fitted on the top end of the slide rod 1406. The two rings are respectively fitted to the upper and lower surfaces of the bottom of the frame 6. This is to make the slide rod 1406 more stable when it rotates relative to the frame 6. A third bevel gear 1407 is fixed to the top end of the slide rod 1406. A fourth bevel gear 1408 is meshed with the surface of the third bevel gear 1407. The fourth bevel gear 1408 is fixedly connected to one end of the reciprocating screw 802.

[0024] The working principle and usage process of this invention are as follows: In use, a longer rod is first placed on the support platform 3, and the rod is passed between two rotating rollers 501 and out through the through hole on the surface of the L-shaped seat 4. The anti-slip rubber sleeve on the surface of the rotating roller 501 will fit tightly with the rod. When it is necessary to drive the rod to move, the first motor 503 can be started. The first motor 503 can drive one of the rotating rollers 501 to rotate. Under the action of the two flat gears 504, the other rotating roller 501 will also rotate synchronously in the opposite direction, so the rod can be driven to move.

[0025] After moving to the appropriate position, cylinder 701 is activated. The extended end of cylinder 701 can move the horizontal plate 702 downwards. The horizontal plate 702, via the first spring 704, can move the frame 6 downwards. The frame 6 can move the sawing assembly 8 downwards towards the bar. When the frame 6 moves downwards, it can move the two connecting rods 1006. The connecting rods 1006 can move the corresponding connecting blocks 1001 towards the center. The connecting blocks 1001, via the corresponding second spring 1005, can move the corresponding clamping blocks 1004 towards the center, thereby allowing the anti-slip rubber pads on the two clamping blocks 1004 to adhere to the surface of the bar. When the clamping blocks 1004... After the anti-slip rubber pad is attached to the surface of the rod, the saw blade 806 is not in contact with the rod at this time, so the frame 6 will continue to move downwards, and the two connecting blocks 1001 will continue to move towards the middle. At this time, the second spring 1005 will be compressed, so it will apply pressure to the clamping block 1004, thereby making the anti-slip rubber pad on the surface of the clamping block 1004 fit tightly with the surface of the rod, so the rod can be clamped and fixed. When the saw blade 806 fits with the rod, the frame 6 can no longer descend. At this time, the ejector end of the cylinder 701 is extended, and the ejector end of the cylinder 701 will drive the horizontal plate 702 to continue to move downwards. At this time, the four first springs 704 will be compressed.

[0026] Then, the second motor 1401 is started. The second motor 1401 drives the rotating rod 1402 to rotate, which in turn drives the rotating shaft 1303 to rotate. The rotating shaft 1303 drives the impeller 1302 to rotate. Through the water pumping pipe 1304 and the water supply pipe 1305, water in the water storage tank 11 can be pumped to the nozzle 1306 and sprayed onto the cutting part of the bar. When the rotating rod 1402 rotates, it drives the first bevel gear 1403 to rotate. The first bevel gear 1403 drives the second bevel gear 1404 to rotate. The second bevel gear 1404 will... The cylinder 1405 rotates, which in turn rotates the slide rod 1406. The slide rod 1406 rotates the third bevel gear 1407, which in turn rotates the fourth bevel gear 1408. The fourth bevel gear 1408 rotates the reciprocating screw 802, which in turn drives the slider 803 to move horizontally back and forth. The slider 803 then moves the mounting block 805 horizontally back and forth, which in turn moves the saw blade 806 horizontally back and forth, thus performing a sawing operation on the bar. During the sawing process, as the sawing depth increases, the saw blade 806 and the frame 6 move downwards. At this time, the compression of the four first springs 704 decreases. As the frame 6 moves downwards, it also drives the two connecting rods 1006 to continue moving, causing the two connecting blocks 1001 to continue moving towards the center. At this time, the second spring 1005 is further compressed, thus clamping the bar more securely.

[0027] When sawing the bar stock, the water sprayed from the nozzle 1306 can prevent dust from spreading in the air, thus benefiting the health of the workers. The sprayed water will fall into the enclosure 9 and then fall back into the water storage tank 11 through the strip opening on the support platform 3. The filter screen 15 installed in the water storage tank 11 can filter impurities in the water, which can save water resources and achieve the effect of reuse. When a lot of impurities accumulate on the filter screen 15 and block the filter holes, the workers can use two L-shaped handles 16 to remove the filter screen 15 from the water storage tank 11 and then clean it.

[0028] After the bar is sawn, the second motor 1401 is turned off and the cylinder 701 is started. The retraction of the cylinder 701 will drive the horizontal plate 702 to move upward. The horizontal plate 702 can drive the frame 6 to move upward through the second guide rod 705 and the first spring 704, which in turn can drive the saw blade 806 to move upward. The frame 6 can drive the two connecting rods 1006 to move, causing the two connecting blocks 1001 to move outward. At this time, the second spring 1005 will slowly return to its original state until the two clamping blocks 1004 move away from the bar, releasing the clamping restriction on the bar. Then, the conveying component 5 is used to drive the bar to move forward for the next round of cutting operations.
