Description

Technical Field

[0001] The utility model relates to the field of plant board tooling, in particular to a laminated wood board clamping mechanism. Background Art

[0002] When cutting multi-layer laminated plant sheets, you need to stack dozens of layers of sheets first, and then cut them after they are arranged. When cutting, you need to try to fix and compact the sheets at the cutting position to avoid the sheets from rubbing against each other and shifting during the cutting process, which will lead to poor cutting quality and even bad cutting.

[0003] The existing fixing method mainly involves compacting and fixing the circumference of the sheet. However, since the sheet is far away from the cutting position and the sheet is thin and soft, the sheet at the cutting position may still be deformed or misaligned, resulting in a poor fixing effect.

[0024] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0025] Embodiment 1:

[0026] This tooling is mainly used in conjunction with sawing equipment with a workbench to ensure that the multi-layer sheets are compacted and fixed along both sides of the sawing line.

[0027] The main structure includes two mounting beams 1, which are arranged in parallel. On the one hand, the mounting beams 1 are used as mounting carriers for other components, and on the other hand, they are used to be installed and fixed on the sawing equipment used in conjunction to achieve assembly and fixation.

[0028] In specific applications, the mounting beam 1 is used to be fixed on a workbench of a sawing device. The top surface of the mounting beam 1 is coplanar with the workbench surface during installation. The mounting beam 1 is used to support and place sheets on the workbench and is located at the bottom of the sheet together with the workbench.

[0029] The two mounting beams 1 are symmetrically arranged on both sides of the sawing tool and its sawing route, so that the sawing blade can pass through the middle of the two mounting beams 1 and perform reciprocating sawing in the middle of the two mounting beams 1 .

[0030] There is a cutting channel between the two mounting beams 1, and a swing arm 7 and a fixed arm 2 are sequentially arranged above the cutting channel along its length direction. One end of the swing arm 7 is hinged to the fixed arm 2, and the end of the fixed arm 2 away from the swing arm 7 is provided with a fixing seat 21 integrally formed therewith, and the bottom of the fixing seat 21 is welded and fixed to one end of the mounting beam 1.

[0031] A first pressure frame 3 is provided below the fixed arm 2 and is lifted and lowered relative to it. A vertically extending first light rod 4 is fixed to the top of the first pressure frame 3. The first light rod 4 penetrates the fixed arm 2 and slides up and down with the fixed arm 2. A first cylinder 5 is fixedly installed on the fixed arm 2. A first cylinder rod 6 is provided at the bottom end of the first cylinder 5 to cooperate with it. The bottom end of the first cylinder rod 6 is fixed to the top of the first pressure frame 3. Based on the drive of the first cylinder rod 6 and the auxiliary guidance of the first light rod 4, the lifting stroke of the first pressure frame 3 is driven and controlled.

[0032] An upwardly extending articulated seat 12 is provided at one end of the fixed arm 2 close to the swing arm 7, and a third cylinder 13 located above the fixed arm 2 is hingedly installed on the top of the articulated seat 12. One end of the third cylinder 13 is provided with a third cylinder rod 14 matched therewith, and one end of the third cylinder 13 close to the third cylinder rod 14 is rotatably connected to the articulated seat 12 on both sides, and a fixed shaft 15 is fixed on the top of the swing arm 7, and the end of the third cylinder rod 14 is hinged to the fixed shaft 15, so that the driving and control of the swing angle of the swing arm 7 are realized based on the third cylinder 13.

[0033] A second pressure frame 8 with a stroke of approaching or moving away from the swing arm 7 is provided below the swing arm 7, a second light rod 9 vertically fixed thereto is fixed on the top of the second pressure frame 8, the top of the second light rod 9 passes through the swing arm 7 and slides with it, a second cylinder 10 is fixedly mounted on the swing arm 7, a second cylinder rod 11 telescopically matched thereto is provided at the bottom end of the second cylinder 10, the bottom end of the second cylinder rod is fixed on the top of the second pressure frame 8, based on the drive of the second cylinder 10 and the auxiliary guidance of the second light rod 9, the control of the second pressure frame 8 approaching or moving away from the swing arm 7 is realized.

[0034] The length direction of the second pressing frame 8 is in the same direction as the cutting channel, and the first pressing frame 3 and the second pressing frame 8 are centrally located in the cutting channel.

[0035] The first pressing frame 3 and the second pressing frame 8 have the same width.

[0036] The first pressing frame 3 includes a first top plate 16 and a first side plate 17. The bottom ends of the first cylinder rod 6 and the first polished rod 4 are fixed on the first top plate 16. The first side plate 17 is composed of two pieces and is vertically arranged. The top sides of the first side plates 17 are vertically and symmetrically fixed on both sides of the long sides of the first top plate 16. Based on the above structure, the cross section of the first pressing frame 3 is in a "ㄇ" shape.

[0037] The structure of the second press frame 8 is the same as that of the first press frame 3. The second press frame 8 includes a second top plate 18 and a second side plate 19. The bottom ends of the second cylinder rod 11 and the second light rod 9 are fixed on the second top plate 18. The second side plate 19 is upright and includes two pieces symmetrically relative to the second top plate 18. The top sides of the second side plates 19 are vertically fixed on both sides of the second top plate 18.

[0038] The "ㄇ"-shaped structure connecting the first pressing frame 3 and the second pressing frame 8 can realize compaction of the sheet along both sides of its cutting route. The fixed position is along the cutting path and adjacent to the cutting position, which can ensure the fixation of the sheet near the cutting.

[0039] The swing arm 7 and the fixed arm 2 are also "ㄇ"-shaped structures, and a clearance groove is provided at the bottom of the swing arm 7 and the fixed arm 2. The width of the clearance groove is greater than the width of the first pressure frame 3 and the second pressure frame 8. When the first pressure frame 3 / the second pressure frame 8 rises, they can enter the clearance groove, providing more lifting space.

[0040] The fixing process of the plate by this tooling includes:

[0041] Initial stage: the first press frame 3 and the second press frame 8 are both lifted to their high positions to leave space below, and the swing arm 7 is swung upward so that the end of the swing arm 7 away from the fixed arm 2 is a trumpet structure that opens upward, making it convenient for workers to insert and stack the sheets layer by layer from there.

[0042] Press down to fix:

[0043] Start the third cylinder 13, and the swing arm 7 falls until the swing arm 7 is horizontal;

[0044] Start the first cylinder 5 and the second cylinder 10 to control the first pressing frame 3 and the second pressing frame 8 to fall down respectively until the bottom side presses on the top surface of the sheet, and then cutting can be carried out;

[0045] Lift up and release: After the cutting is completed, the first pressing frame 3 and the second pressing frame 8 are lifted up to remove the cut sheet.

[0046] The above operation process realizes the fixation of the sheet near the cutting position along the cutting path during the cutting process. The fixing effect is very good, which can greatly reduce the problems of the sheet being misaligned, moved, deformed, etc. during cutting, thereby improving the cutting quality.

[0047] Embodiment 2:

[0048] This example can be used with a relatively simple sawing mechanism. This example includes a frame body, and the frame body has a support frame 20 on the top. The top surface of the support frame 20 is horizontal and is used to place sheets. Two mounting beams 1 are fixed in the center of the support frame 20. A cutting channel is provided between the two mounting beams 1. The sawing equipment is installed below the cutting channel, and the sawing blade reciprocates through the cutting channel. Other structures are the same as those in Example 1.
