DETAILED DESCRIPTION
[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0026] See also Figure 1-6The utility model provides a technical solution: a wood longitudinal and transverse saw with a pressing mechanism, comprising a frame 1, a saw blade installation box 2 is slidably connected to the surface of the frame 1, a saw blade protection shell 3 is arranged on the saw blade installation box 2, and two pressing plates 9 are fixedly connected to the surface of the saw blade protection shell 3. The two pressing plates 9 are arranged to be relatively inclined, so that the two pressing plates 9 can press a larger area of the wooden board, so that when the device cuts the wooden board, the wooden board can be prevented from jumping, etc., and the stability of the device during the cutting process is ensured.
[0027] The inner wall of the frame 1 is slidably connected with a transverse feeding plate 5 for transversely feeding the wooden boards. The surface of the transverse feeding plate 5 is slidably connected with two placement plates 6. The inside of the transverse feeding plate 5 is rotatably connected with a bidirectional threaded rod 7. The surface of the bidirectional threaded rod 7 passes through the surfaces of the two placement plates 6 and is connected with the internal threads of the two placement plates 6. The internal threads of the two placement plates 6 match the threads at both ends of the two bidirectional threaded rods 7 respectively, thereby ensuring that the bidirectional threaded rod 7 can smoothly drive the two placement plates 6 to move relative to or away from each other when rotating, so that the device can clamp and fix wooden boards of different sizes.
[0028] Furthermore, the surfaces of the two placement plates 6 are slidably connected with equidistantly arranged clamping strips 16, and the inside of the clamping strips 16 is slidably connected with two locking balls 18, and the opposite sides of the two locking balls 18 are fixedly connected with a first spring 19 for resetting the two locking grooves 8. Equidistantly arranged locking grooves 8 are provided on both sides of the inside of the transverse feed plate 5, and the surfaces of the locking balls 18 are slidably connected with the inner walls of the locking grooves 8, and then the position of the clamping strip 16 can be limited by the arrangement of the locking balls 18 and the locking grooves 8, thereby avoiding the clamping strip 16 from sliding randomly on the transverse feed plate 5, and at the same time does not affect the staff's pushing and changing of the position of the clamping strip 16, thereby avoiding the existence of the clamping strip 16 affecting the staff's longitudinal cutting of the wood.
[0029] Both sides of the transverse feed plate 5 are rotatably connected with handles 15 with a Z-shaped cross-section, the surface of one handle 15 is fixedly connected to one end of the two-way threaded rod 7, the surface of the other handle 15 is slidably connected to the inside of the two-way threaded rod 7, the surface of the handle 15 slidably connected to the inside of the two-way threaded rod 7 is slidably connected with movable blocks 13 arranged equidistantly around the circumference, the cross-section of the upper end of the movable block 13 is a right triangle, the surface of the movable block 13 is fixedly connected with a second spring 12, the end of the second spring 12 away from the movable block 13 is fixedly connected to the inside of the handle 15 for resetting the movable block 13, the interior of the two-way threaded rod 7 is provided with sliding grooves 14 arranged equidistantly around the circumference, the number of the sliding grooves 14 matches the number of the movable blocks 13, the cross-section of the sliding grooves 14 is also a right triangle, the surface of the movable block 13 is slidably connected to the inner wall of the movable block 13.
[0030] Furthermore, a torsion spring 17 is movably sleeved on the surface of the handle 15 that is slidably connected to the inside of the bidirectional threaded rod 7. The two ends of the torsion spring 17 are respectively fixedly connected to the surface of the handle 15 and the inside of the horizontal feed plate 5 to reset the handle 15. In the initial state of the device, the handle 15 that is slidably connected to the inside of the bidirectional threaded rod 7 is inclined. At the same time, the setting of the handle 15 makes it convenient for the staff to rotate the bidirectional threaded rod 7, thereby improving the use effect of the device.
[0031] The handle 15 slidably connected to the inside of the two-way threaded rod 7 is slidably connected to a limiting rod 11 at one end away from the two-way threaded rod 7. A third spring 10 is movably sleeved on the surface of the limiting rod 11. The two ends of the third spring 10 are respectively fixedly connected to the surface of the limiting rod 11 and the inside of the handle 15. A horizontal U-shaped limiting groove 4 is opened on one side of the inner wall of the frame 1. The vertical groove of the limiting groove 4 is inclined, and the depth of the horizontal groove on the limiting groove 4 gradually becomes shallower. The depth of the vertical oblique groove of the limiting groove 4 is the same as the shallowest depth of the horizontal groove on the handle 15, and the depth of the lower horizontal groove of the limiting groove 4 is the same as the deepest depth of the upper horizontal groove of the limiting groove 4. The surfaces of the handle 15 and the limiting rod 11 are both slidably connected to the inner wall of the limiting groove 4.
[0032] Furthermore, when cutting the wooden board, the two placing plates 6 are driven to move relative to each other by rotating a handle 15 to clamp the wooden board. When the handle 15 is rotated, the handle 15 drives the movable block 13 to rotate, so that the vertical edge of the movable block 13 presses the vertical inner wall of the slide groove 14, thereby ensuring that when the handle 15 is rotated, the bidirectional threaded rod 7 can be smoothly driven to rotate, so that the two placing plates 6 can smoothly clamp the wooden board. While the handle 15 is rotating, the torsion spring 17 is twisted, so that when the handle 15 is no longer rotated, the handle 15 is driven to reverse under the elastic force of the torsion spring 17. At this time, the handle 15 drives the movable block 13 to reverse, so that the inclined surface of the movable block 13 is pressed against the inclined surface of the inner wall of the slide groove 14. The second spring 12 is pressed against the movable block 13, thereby pushing the movable block 13 to retract into the handle 15 and compressing the second spring 12 until the movable block 13 corresponds to the slide groove 14 again. Under the elastic force of the second spring 12, the movable block 13 returns to its original state and is inserted into the slide groove 14 again, and the above action is repeated until the elastic force of the second spring 12 completely disappears. At this time, the handle 15 slidably connected to the inside of the two-way threaded rod 7 returns to its original position, and then through the setting of the slide groove 14, the second spring 12 and the movable block 13, it is ensured that the staff can smoothly drive the two placement plates 6 to clamp the wooden board after turning the handle 15, and at the same time, it can not affect the clamping between the two placement plates 6 after letting go, thereby ensuring the stability of the device in fixing the wooden board and ensuring the stable cutting of the wooden board by the device.
[0033] Then, the transverse feeding plate 5 is started to feed the wooden board transversely and cut the wooden board transversely. The movement of the transverse feeding plate 5 drives the two handles 15 to move synchronously, so that the handle 15 slidably connected to the inside of the two-way threaded rod 7 is sent into the upper transverse groove of the limiting groove 4. Since the upper transverse groove of the limiting groove 4 gradually becomes shallower, as the transverse feeding plate 5 is fed, the inner wall of the limiting groove 4 squeezes the limiting rod 11, causing it to retract into the handle 15 and compress the third spring 10. After the transverse cutting of the wooden board is completed, the transverse feeding plate 5 continues to be fed, so that the handle 15 starts to slide in the vertical inclined groove of the limiting groove 4. Since the handle 15 is initially inclined, this When the board 1 is moved horizontally, the handle 15 is rotated again, and the torsion spring 17 is twisted, and the two placement plates 6 are driven to move relative to each other to a certain extent, so that the two clamping strips 16 clamp the board again, so that when the device cuts the board horizontally, the fixing force of the board is weakened due to the existence of the cutting groove of the board, thereby avoiding the shaking during the cutting process or the need for manual secondary reinforcement, thereby improving the cutting quality of the board by the device and the cutting efficiency of the board, and having high promotion value and practicality.
[0034] Furthermore, as the transverse feed plate 5 is fed forward, the handle 15 moves to the lower transverse groove of the limiting groove 4. Since the depth of the limiting groove 4 becomes deeper at this time, the limiting rod 11 returns to its original state under the elastic force of the third spring 10, and the transverse feed plate 5 returns to perform a second transverse cut on the wooden board. However, since the depth of the vertical oblique groove of the limiting groove 4 is less than the depth of the lower transverse groove, there is a step between the vertical oblique groove of the limiting groove 4 and the lower transverse groove of the limiting groove 4. Therefore, the handle 15 is blocked by the step and cannot return along the vertical oblique groove of the limiting groove 4 again. Instead, it slides back in the lower transverse groove of the limiting groove 4 until it is separated from the lower transverse groove of the limiting groove 4. Under the elastic force of the torsion spring 17, it returns to its original state, and then moves along the upper transverse groove of the limiting groove 4 again to continue to transversely cut the wooden board, thereby ensuring the continuous processing of the device on the transverse cutting of the wooden board, improving the use effect of the device, and having a high promotion value.
[0035] Then, the wooden board can be loosened by simply rotating the handle 15 fixedly connected to the bidirectional threaded rod 7, and the cut wooden board can be taken out.
[0036] Working principle: Turn a handle 15 to drive the two placement plates 6 to move relative to each other, clamp the wooden board, then start the transverse feeding plate 5 to feed the wooden board horizontally, cut the wooden board horizontally, drive a handle 15 to move in the limiting groove 4, and after the transverse cutting of the wooden board is completed, make the transverse feeding plate 5 continue to feed, make the handle 15 slidingly connected to the inside of the two-way threaded rod 7 rotate, drive the two placement plates 6 to move relative to each other to a certain extent again, clamp the wooden board again, thereby avoiding the existence of the cutting notch to reduce the fixing effect of the device on the wooden board.
[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
