It can realize the movement of the working rack and the cutting tool by controlling the first hydraulic rod and the second hydraulic rod, so that the plate only needs to be fixed, and the plate is cut by controlling the cutting tool.

[0003] In this scheme, the plate is fixed on both sides of the machine body by the threaded rods, and only the displacement of the cutting tool is needed to realize the accurate cutting of the plate, without the need for repositioning and clamping the plate. However, in the actual cutting process, the plate is only fixed from both sides, and it is easy to cause the plate to vibrate due to equipment vibration during the cutting process. When the plate vibrates, the relative position between the cutting tool (such as a saw blade) and the plate will constantly change slightly. For example, when cutting a wooden plate with a circular saw, if the plate vibrates, the saw blade will produce slight deviation in the vertical and horizontal directions, which will cause the cutting path to be no longer a straight line, resulting in a wavy or jagged uneven surface of the cut, and the width of the cut will also increase due to vibration, affecting the accuracy of the cutting size.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Example 1, as Figures 1-5 As shown, a furniture processing board cutting device according to an embodiment of this application includes a processing table 1. Two lifting components 2 are symmetrically slidably connected to both sides of the processing table 1. A top displacement component 3 is fixedly connected to the top of the two lifting components 2. A cutting component 4 is fixedly connected to the displacement end of the top displacement component 3. The cutting component 4 includes a motor 41 and a saw blade 42. The saw blade 42 is keyed to the output shaft of the motor 41. It should be noted that in the specific embodiment of this application, the lifting components 2 can be existing technologies with linear displacement functions such as electric push rods, which are only used to control the lifting of the top displacement component 3. This will not be elaborated here.

[0024] Furthermore, the displacement end of the top displacement component 3 is also fixedly connected to an upper end pressing component 5. The upper end pressing component 5 is symmetrically arranged with multiple upper end rollers 53 on both sides of the saw blade 42. The multiple upper end rollers 53 elastically abut against the plate to be cut. The side of the processing table 1 that carries the plate is provided with a concave surface 14. A bottom support component 6 is slidably arranged in the concave surface 14. The bottom support component 6 is fixedly connected to two lifting components 2. Multiple bottom end rollers 612 are provided on the bottom support component 6 that abut against the bottom side of the plate to be cut.

[0025] It should be noted that the elastic force of the upper end roller 53 elastically abutting the plate is set to make the cutting position of the plate not produce independent amplitude when the plate is vibrated (i.e., the cutting position of the plate remains stable relative to the saw blade 42), and the highest point of the bottom end roller 612 is at the same height as the end face of the plate supported on both sides of the processing table 1, which facilitates better support of the plate and avoids "dropping of the belly" (sagging) or arching of the plate during the supporting process, thereby ensuring the stability of the plate during the cutting process.

[0026] Further, it should be noted that the position of the bottom end roller 612 corresponds to the upper end roller 53 and forms symmetry on both sides of the saw blade 42, leaving a cutting space for the saw blade 42.

[0027] Specifically, as shown in Figure 1 and Figure 4 , the processing table 1 is symmetrically provided with a first sliding groove 11 and a second sliding groove 12 on both sides, and one side of the processing table 1 supporting the plate is symmetrically provided with two fixing assemblies 13, which include a pressing plate 131 that is detachably fixed to the processing table 1 by a bolt 132. It can be understood that after the plate is placed on the processing table 1, the plate is fixed and clamped on the processing table 1 by the pressing plate 131 and the bolt 132 on both sides.

[0028] As shown in Figure 4 , the lifting member 2 is respectively fixed with a first sliding block 21 and a second sliding block 22, the first sliding block 21 is limited to slide in the first sliding groove 11, and the second sliding block 22 is limited to slide in the second sliding groove 12. It should be noted that the power for the displacement of the lifting member 2 along the first sliding groove 11 and the second sliding groove 12 can be realized by an external linear displacement device or a device with linear displacement function, which will not be described here.

[0029] As shown in Figure 1 , Figure 2 and Figure 4 , the top displacement assembly 3 includes a top support frame 31 fixed to the top end of the lifting member 2, and a top displacement member 32 fixed to the top support frame 31, and the motor 41 is fixed to the displacement part of the top displacement member 32. It should be noted that the top displacement member 32 can be a linear slide or other existing technology with linear displacement function.

[0030] As shown in Figures 1-4 , the upper end abutting assembly 5 further includes a bracket 51 fixed to the displacement part of the top displacement member 32, the bracket 51 is fixed with a plurality of elastic expansion members 52, and the other end of the plurality of elastic expansion members 52 is in one-to-one correspondence with and rotatably connected to the plurality of upper end rollers 53.

[0031] As shown in Figure 5As shown, the elastic expansion piece 52 comprises a fixed cylinder 521 fixed to the support 51, a plug-in rod 522 is slidingly inserted into the fixed cylinder 521, a positioning rod 523 is fixed in the fixed cylinder 521, a spring 524 is sleeved on the positioning rod 523, the two ends of the spring 524 abut against the inner wall of the fixed cylinder 521 and the plug-in rod 522, a third sliding groove 525 is arranged in the plug-in rod 522, and the positioning rod 523 is slidingly inserted into the third sliding groove 525. It should be noted that in the initial state, the upper end roller 53 is closer to the lower plate relative to the saw blade 42, so that when the saw blade 42 approaches the upper side of the plate, the upper end roller 53 first abuts against the plate, and with the descent of the saw blade 42, the plug-in rod 522 is inserted into the inside of the fixed cylinder 521 and compresses the spring 524. Under the action of the elastic force of the spring 524, the upper end roller 53 will exert an elastic pressure on the plate to suppress the vibration of the plate.

[0032] As shown in the drawings, Figures 2-4 The bottom support assembly 6 comprises a support 61 and a driving assembly 62. The support 61 comprises a base 611, and a plurality of bottom end rollers 612 are rotatably connected to the base 611. The driving assembly 62 comprises a screw rod 621 and a sliding rod 622. The screw rod 621 is in threaded connection with the base 611, and the sliding rod 622 is in sliding connection with the base 611.

[0033] Specifically, both ends of the screw rod 621 are rotatably penetrated through the second sliding blocks 22 arranged symmetrically and extend to the outside of the machining table 1, and both ends of the sliding rod 622 are fixedly connected to the second sliding blocks 22 arranged symmetrically.

[0034] It can be understood that the bottom support assembly 6 will be synchronously displaced along the first sliding groove 11 and the second sliding groove 12 on the machining table 1 with the lifting piece 2, and at the same time, the rotation of the screw rod 621 can cause the axial displacement of the bottom end rollers 612 along the sliding rod 622, so as to adjust the position of the bottom end rollers 612, so that the bottom end rollers 612 and the upper end roller 53 correspond to each other and support the upper and lower sides of the plate, and at the same time, a cutting space is left for the saw blade 42.

[0035] The present application can keep the plate stable during cutting by abutting against the upper and lower sides of the plate, thereby reducing the phenomenon of uneven cut caused by vibration and the phenomenon of increased cut width caused by vibration.

[0036] Among them, the elastic abutment at the upper end of the plate can not only keep the plate stable, but also avoid damage to the surface of the plate caused by rigid abutment.

[0037] In embodiment 2, in embodiment 1, the elastic expansion piece 52 can also be replaced by a damping device in the prior art to achieve flexible abutment of the upper end roller 53 to the upper end surface of the plate (still with a certain pressure, and the size of the pressure can suppress the vibration of the plate) while more effectively reducing the vibration phenomenon of the plate.

[0038] In the embodiment 3, the base 611 needs to follow the corresponding displacement of the upper end roller 53 (relative to the length and width direction of the machining table 1) so as to form the corresponding abutting action on the top and bottom sides of the plate, thereby the driving assembly 62 can be designed as the prior art as the top displacement member 32, so as to better synchronize the displacement of the upper end roller 53 and the bottom end roller 612, and also reduce the working strength of the workers.

[0039] In the embodiment 4, the dust removal device in the prior art can also be additionally arranged at the base 611, so as to remove the debris falling to the base 611 during the cutting process. Specifically, a hose can be used to cooperate with an external dust removal equipment, and the inlet of the hose is arranged on the base 611.

[0040] It should be noted that the specific type and specification of the bolt 132, the lifting member 2, the motor 41, the saw blade 42, the spring 524 and the screw rod 621 need to be determined according to the actual specification of the device, and the specific selection calculation method adopts the prior art in the field, so it will not be described in detail.

[0041] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
