Technical Field
[0001] The utility model belongs to the technical field of woodworking, and in particular relates to a woodworking cutting saw. Background Art
[0002] Carpenters need to use a cutting saw device during the process of cutting wood. The existing cutting device is generally carried out on a workbench, and the motor is installed under the table. The cutting saw passes through the table. When cutting the wood, after making marks on the wood, the wood is pushed close to the cutting saw for cutting.
[0003] However, the cutting saw device of the prior art does not have a guide device for limiting the position of the wood. As a result, if the wood is long, the wood may easily deviate from the stroke when it is pushed forward, causing the wood to be cut crookedly. Secondly, when cutting the wood, the prior art needs to push the end of the wood marking line so that the wood can be cut accurately. When the cutting saw approaches the end of the wood, there is a certain safety risk, and the carpenter's hand is easy to be cut. If the wood is not pushed at the end of the wood marking line, it is easy to cause the wood cutting to deviate. Therefore, the woodworking cutting device of the prior art has certain disadvantages in use.
[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION
[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0029] A woodworking cutting saw, such as Figure 1 , Figure 2 , Figure 5 As shown, it includes a platform 10, which is L-shaped. Four groups of supporting legs are fixedly arranged at the bottom of the platform 10. A motor is fixedly arranged on the vertical inner wall of the platform 10, and a cutting saw 15 is fixedly arranged at the output end of the motor. A workbench 11 is fixedly arranged on the top wall of the platform 10. A rectangular avoidance opening is opened in the middle of the workbench 11, and the top of the cutting saw 15 passes through the avoidance opening. Limiting plates 20 are movably arranged on the two side walls of the top of the platform 10. The two limiting plates 20 are used for guiding and limiting the wood. A rotation adjustment structure is arranged between the limiting plates 20 and the wall surface of the workbench 11; a clamping assembly for clamping the wood is arranged on the side wall where the two limiting plates 20 are close to each other, and the clamping assembly includes a pressing plate 31, and a guiding structure for guiding the wood is also arranged on the wall surface of the limiting plate 20 located below the pressing plate 31.
[0030] like Figure 3 , Figure 5 , Figure 7 As shown, the rotation adjustment structure includes three limit blocks 21 fixedly mounted on the bottom wall of the limit plate 20, and three slide grooves 22 are provided on the two side walls of the top of the workbench 11. The limit blocks 21 are rectangular, and the slide grooves 22 are also rectangular. The limit blocks 21 are movably engaged in the slide grooves 22. The slide grooves 22 located in the middle of the two sides are rotatably mounted with threaded rods 24, one end of the threaded rod 24 is rotatably mounted in the inner wall of the slide groove 22, and the other end of the threaded rod 24 movably penetrates the wall of the workbench 11, and the other end of the threaded rod 24 is fixedly mounted with a turntable 25, and the remaining two slide grooves 22 on each side are fixedly mounted with guide rods 23, and the guide rods 23 movably penetrate the limit blocks 21, and the middle limit block 21 is provided with threaded holes, and the threaded rods 24 are threadedly connected with the threaded holes.
[0031] like Figure 5 , Figure 6As shown, the limit plate 20 is L-shaped, and the horizontal ends of the two limit plates 20 are close to each other. The pressure plate 31 is also L-shaped. The two limit plates 20 are close to each other on one side of the wall to which the limit plates 20 are provided. The limit groove 30 is also L-shaped. The vertical end of the pressure plate 31 is movably engaged in the limit groove 30, and the horizontal end of the pressure plate 31 is located below the horizontal end of the limit plate 20. The clamping assembly also includes a plurality of sets of screws 32 threadedly connected to the horizontal end of the limit plate 20. The screws 32 penetrate the horizontal end of the limit plate 20, and the bottom ends of the screws 32 are rotatably connected to the top wall of the horizontal end of the pressure plate 31. A plurality of sets of springs 33 are fixedly installed on the bottom wall of the cavity of the limit groove 30, and the top ends of the springs 33 are fixedly connected to the bottom wall of the vertical end of the pressure plate 31.
[0032] like Figure 7 As shown, the guide structure includes a plurality of guide rollers 35 movably arranged on the lower side wall surface of the limiting plate 20. The lower side walls of the two limiting plates 20 close to each other are provided with a plurality of rotation grooves 34 distributed at equal intervals, and the guide rollers 35 are movably installed in the rotation grooves 34 through a rotating shaft, and a side arc-shaped wall surface of the guide rollers 35 extends out from the rotation grooves 34.
[0033] like Figure 1 , Figure 4 As shown, a protective cover 12 for protecting the cutting saw 15 is also provided on the upper side of the cutting saw 15. The protective cover 12 is arc-shaped, and an arc-shaped inner groove is opened at the bottom of the protective cover 12. The top of the cutting saw 15 extends into the inner groove at the bottom of the protective cover 12. Fixed brackets 13 are provided between the protective cover 12 and the top walls on both sides of the workbench 11. The fixed brackets 13 are L-shaped, and both ends of the fixed brackets 13 are fixedly connected with connecting plates 14, and the connecting plates 14 are fixedly installed with the protective cover 12 and the table body 10 by screws.
[0034] When in use, mark the mark line to be cut on the wood, put the wood on the workbench 11, align the mark line with the cutting saw 15, and then rotate the turntables 25 on both sides. When the turntables 25 rotate, the threaded rod 24 is driven to rotate. The threaded rod 24 is threadedly connected to the middle limit block 21. Therefore, the position of the limit plate 20 can be adjusted by the turntable 25. By rotating the turntable 25, the two limit plates 20 move closer to each other. After the two limit plates 20 are close to each other, the two limit plates 20 clamp the two side walls of the wood through the guide structure. At this time, the wood is limited by the limit plates 20 on both sides, and then by rotating the screw rod 32, when the screw rod 32 moves downward, the screw rod 32 presses the pressure plate 31, so that the pressure plate 31 moves vertically downward, and the spring 33 is compressed, and at the same time, the horizontal wall surface of the pressure plate 31 limits the top wall surfaces on both sides of the wood. There is no need to lock the wood, and it is only necessary to limit the wood reasonably. At this time, the wall surfaces on both sides of the wood are in contact with the guide rollers 35, and the marking line on the wood is aligned with the cutting saw 15. The working switch of the motor is turned on, and the motor drives the cutting saw 15 to rotate. At this time, the wood is pushed toward one side of the cutting saw 15 for horizontal movement. When the wood is close to the cutting saw 15, the wood is accurately cut. When the wood is being cut, the wood is always in a stable limited state. When the end of the wood is about to approach the cutting saw 15, only any side of the wood needs to be pushed at will to allow the wood to be accurately cut. There is no need for people to hold the marked end of the wood to push, which can reduce the risk of operation.
[0035] It is worth noting that, through the protective cover 12, the protective cover 12 can provide certain protection for the cutting saw 15, reduce or avoid the possibility of human body contacting the cutting saw 15, and improve the safety of the operation.
