Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Reference Figure 1 , Figure 2 , Figure 4The utility model provides an embodiment: a folding telescopic dust-free woodworking table saw, comprising a machine table 1 for supporting the overall device, a cutting knife 2 is arranged on the upper surface of the machine table 1, and the cutting knife 2 is located at the center of the upper surface of the machine table 1. The cutting knife 2 is used to cut the plate. A positioning component is arranged on the upper surface of the machine table 1. The positioning component can clamp and position the plate to ensure that the plate will not be offset when it is cut and pushed forward. The positioning component can block the left and right sides of the plate to prevent impurities generated during cutting from falling from the left and right sides of the machine table 1. A folding telescopic component is arranged on the rear surface of the machine table 1, and the folding telescopic component can change the length of the machine table 1 When cutting the plate, even if the plate is long, it can provide support for the plate to ensure that the plate will not be lifted up due to the large suspended part when cutting, ensuring the stability of the device operation and the processing quality. A lifting component is provided on the upper surface of the machine 1, and the positioning component includes a clamping plate 31. A positioning groove 301 is provided on the front surface of the machine 1. Two groups of clamping plates 31 are provided, and multiple groups of positioning grooves 301 are provided. The clamping plates 31 and the positioning grooves 301 are symmetrically distributed with respect to the center line of the machine 1. The inner wall of the clamping plate 31 is elastically connected to a positioning block 34 through a compression spring 33, and the rear end of the positioning block 34 fits with the positioning groove 301.
[0034] Reference Figure 1 , Figure 2 , Figure 4 The positioning assembly also includes a pull rod 32, a protrusion is provided at the front end of the pull rod 32, the protrusion is located on the front side of the splint 31, and the surface of the protrusion is provided with anti-slip grooves for easy gripping. The pull rod 32 passes through and is slidably connected to the front surface of the splint 31, sliding in the front and rear directions. The rear surface of the pull rod 32 is fixedly connected to the front surface of the positioning block 34. The pull rod 32 and the positioning block 34 will move synchronously. Pulling the pull rod 32 can disengage the positioning block 34 and the positioning slot 301 to release the limitation of the splint 31.
[0035] Reference Figure 1 - Figure 3 The lifting assembly includes a turntable 41, and a threaded rod 44 is fixedly connected to the lower surface of the turntable 41. When the turntable 41 rotates, the threaded rod 44 is driven to rotate synchronously. The threaded rod 44 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The threaded rod 44 is self-locking. The inner wall of the clamping plate 31 is slidably connected to a slide plate 42, and the slide plate 42 slides longitudinally. The left surface of the slide plate 42 passes through and is slidably connected to a baffle 43, and the two slide horizontally. The upper surface of the machine 1 is fixedly connected to a slide bar 45. There are two groups of slide bars 45, which are fixed at the left front and right front corners of the upper surface of the machine 1.
[0036] Reference Figure 1 , Figure 5The folding and telescopic assembly includes a support plate 52, which can provide support for the plate. The support plate 52 is initially in a vertical state, which can reduce the area of the device and facilitate placement. The front end of the left surface of the support plate 52 is fixedly connected with a rotating shaft 53, and the support plate 52 rotates around the center of the rotating shaft 53. The inner wall of the machine 1 is elastically connected with a shift block 51 through a connecting spring 54. A card slot 501 is provided on the left surface of the rotating shaft 53, and the card slot 501 corresponds to the shift block 51. The card slot 501 is provided in a square shape and is located at the center of the rotating shaft 53.
[0037] Reference Figure 1 , Figure 2 , Figure 4 The clamping plate 31 is slidably connected to the upper surface of the machine table 1 and slides horizontally. The positioning block 34 is inserted into the inner wall of the positioning groove 301, which can limit the clamping plate 31. The right surface of the positioning block 34 is set as an inclined surface. By squeezing the inclined surface of the positioning block 34, the positioning block 34 will move forward and disengage from the positioning groove 301 to release the limitation of the clamping plate 31. The left surface of the positioning block 34 is set as a plane. When squeezed, the positioning block 34 will not be displaced, thereby playing a one-way limiting role. One end of the compression spring 33 is fixedly connected to the front surface of the positioning block 34, and the other end of the compression spring 33 is fixedly connected to the inner wall of the front side of the clamping plate 31. When the positioning block 34 moves forward, it will squeeze the compression spring 33 to generate a reaction force.
[0038] Reference Figure 1 - Figure 3 The threaded rod 44 passes through and is threadedly connected to the upper surface of the splint 31, the sliding rod 45 passes through and is slidably connected to the lower surface of the baffle 43, and a handle is provided on the upper surface of the turntable 41. The lower surface of the handle is fixedly connected to a position of the upper surface of the turntable 41 away from the center of the circle. The handle is convenient for grasping. Grasping the handle and rotating it can drive the turntable 41 to rotate. The lower surface of the threaded rod 44 is rotatably connected to the upper surface of the slide plate 42. When the threaded rod 44 rotates, the threaded rod 44 and the slide plate 42 will move longitudinally.
[0039] Reference Figure 1 , Figure 5 The rotating shaft 53 is rotatably connected to the inner wall of the machine 1, and the shift block 51 is set to be L-shaped. The shift block 51 is inserted into the inner wall of the card slot 501, which can limit the rotating shaft 53 so that the rotating shaft 53 cannot rotate. The right surface of the shift block 51 is set to be square. Every time the rotating shaft 53 rotates 90 degrees, the card slot 501 and the shift block 51 are aligned. When the support plate 52 rotates 90 degrees, the lower surface will contact the machine 1 and will be blocked. The shift block 51 penetrates and is slidably connected to the upper surface of the machine 1, sliding horizontally, and the upper surface of the shift block 51 protrudes from the upper surface of the machine 1.
[0040] Reference Figure 1 , Figure 5One end of the connecting spring 54 is fixedly connected to the left surface of the shift block 51, and the other end of the connecting spring 54 is fixedly connected to the inner wall of the left side of the machine 1. When the shift block 51 moves to the left, it will squeeze the connecting spring 54 to generate a reaction force.
[0041] Working principle: When the device is used, first, the shift block 51 is shifted to the left to disengage the shift block 51 and the card slot 501 to release the limit on the rotating shaft 53, and when the shift block 51 moves, it will also squeeze the connecting spring 54 to generate a reaction force, and then the support plate 52 is rotated to drive the rotating shaft 53 to rotate. When the support plate 52 is rotated to the upper surface and the upper surface of the machine 1, the lower surface of the support plate 52 will be blocked by the machine 1. At this time, the support plate 52 is rotated 90 degrees. At this time, the shift block 51 is released, and the reaction force of the connecting spring 54 will push the shift block 51 to move to the right and engage the card slot 501 to limit the rotating shaft 53, ensuring the stability of the support plate 52 and the rotating shaft 53. After the device is used, the support plate 52 can be folded and stored again by rotating the support plate 52 in the opposite direction in the same way.
[0042] When the support plate 52 is unfolded, the plate to be processed is placed on the support plate 52 and the machine table 1, and then the clamps 31 on both sides are moved toward the center of the machine table 1 to clamp the plate. When the clamps 31 move, the slide plate 42 will be driven to move synchronously, and the slide plate 42 and the baffle plate 43 will slide horizontally, and when the clamps 31 move, the positioning block 34 will be driven to move. When the positioning block 34 moves, the inclined surface will be squeezed by the positioning groove 301. The inclined surface of the positioning block 34 will be squeezed and move forward to disengage from the positioning groove 301 to release the limit on the clamp 31, and will squeeze the compression spring 33 to generate a reaction force. Since the positioning block 34 has an inclined surface only on one side, it can play a one-way limit role, so it can remain stable when clamping the plate.
[0043] Then adjust the height of the baffle 43 according to the thickness of the plate. During adjustment, rotate the turntable 41 to drive the threaded rod 44 to rotate, and the rotating threaded rod 44 will drive the slide plate 42 and the baffle 43 to move longitudinally. When they move to the appropriate position, stop rotating the turntable 41, and the height of the slide plate 42 and the baffle 43 will be stabilized due to the self-locking property of the threaded rod 44.
[0044] Then start the cutting knife 2 and push the plate forward. Most of the waste generated by cutting will be blocked by the clamping plate 31 and the baffle 43 and will not be scattered over a large area, which is convenient for subsequent cleaning. When the plate passes through the baffle 43, the waste remaining on the top will be swept down by the baffle 43 to ensure cleanliness and reduce dust pollution. When cutting is completed, the cutting knife 2 can be closed.
[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
