Description
Technical Field
[0001] The utility model relates to the technical field of positioning tools, in particular to a cutting positioning tool and a cutter for T-shaped furniture board decorative strips. Background Art
[0002] The furniture board decorative strip includes an installation part, and decorative parts extend from the ends of the installation part to both sides to form a T shape. The decorative strip is installed on the grooved part of the furniture board through the installation part. After installation, the decorative part blocks the outside of the grooved part of the furniture board to play a decorative role. Since the decorative part is an exposed part and needs to be made as thin as possible to reduce the protrusion degree, the thickness of the decorative part is usually much smaller than that of the installation part. Before installation, according to the sizes of each furniture board, a cutting tool such as an automatic cutting machine is used to cut the decorative strip into multiple segments of corresponding lengths. During cutting, the mutual friction between the cutting tool and the decorative strip will drive the decorative strip to swing, resulting in dimensional deviation at the cutting position. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a cutting positioning tool for T-shaped furniture board decorative strips. During cutting, using this positioning tool to position the decorative strip can reduce the swing amplitude of the decorative strip, thereby reducing the dimensional deviation at the cutting position. The utility model also provides a cutter. During cutting, using the positioning tool of this cutter to position the decorative strip can reduce the swing amplitude of the decorative strip, thereby reducing the dimensional deviation at the cutting position.
[0004] The inventor decided to use a clamping seat with a card slot as the positioning tool. During cutting, the decorative strip is clamped into the card slot to achieve positioning, so that the swing amplitude of the decorative strip can be reduced, thereby reducing the dimensional deviation at the cutting position.
[0005] At the beginning, the inventor directly opened a T-shaped card slot on the clamping seat. During cutting, the T-shaped decorative strip is clamped into the card slot for positioning. After practice, it is found that the clamping seat with a T-shaped card slot has a weak positioning effect on the decorative strip. After research, the inventor found that whether there is a dimensionally matching clamping point between the decorative strip and the card slot determines whether the decorative strip can be firmly clamped in the T-shaped card slot. Specifically: (1) Whether there is a dimensionally matching clamping point between the decorative part of the decorative strip and the upper part of the T-shaped card slot depends on the dimensional matching degree between the width of the decorative strip and the upper part of the card slot; (2) Whether there is a dimensionally matching clamping point between the installation part of the decorative strip and the lower part of the T-shaped card slot depends on the dimensional matching degree between the installation part of the decorative strip and the lower part of the card slot. The width and the installation part size of the decorative strip are relatively large, and correspondingly, the tolerance during processing is also relatively large, resulting in a low dimensional matching degree between the decorative strip and the T-shaped card slot, and there is no dimensionally matching clamping point between the decorative strip and the card slot. Therefore, the decorative strip cannot be firmly clamped in the T-shaped card slot. For this reason, the inventor redesigned the shape of the card slot and designed the following positioning tool.
[0006] To solve the above technical problems, the cutting and positioning tool for the T-shaped furniture board decorative strip of the present utility model includes a clamping seat. The clamping seat is provided with a card slot in the front-back direction, and the slot opening of the card slot faces outward. The decorative strip in the front-back direction is clamped and installed at an angle where one side of the decorative part is outside and the other side is inside. The card slot includes a first card slot for the installation part of the decorative strip to be inserted, and further includes a second card slot opened at the bottom of the first card slot for the inner side of the decorative part of the decorative strip to be inserted. The end of the card slot is open for the decorative strip to extend to the outside.
[0007] Furthermore, the first card slot is compatible with the outer side of the decorative part of the decorative strip.
[0008] Furthermore, a pressing block is provided outside the slot opening of the first card slot for pressing the decorative strip inward.
[0009] Furthermore, the pressing block presses on the clamping seat, and the clamping seat also serves as a limiting part to limit the pressing block.
[0010] Furthermore, it includes a driving mechanism drivingly connected to the pressing block, and the driving mechanism drives the pressing block to approach the clamping seat until the pressing block presses the decorative strip.
[0011] Furthermore, the first card slot has a width of 4 - 5 mm and a depth of 2.5 - 4.5 mm; the second card slot has a width of 0.5 - 1.5 mm and a depth of 0.5 - 1.5 mm.
[0012] Furthermore, the second card slot is opened at the side edge of the bottom of the first card slot; the cross-section of the first card slot is rectangular, and / or the cross-section of the second card slot is rectangular.
[0013] The cutter of the present utility model includes a cutting tool for cutting the T-shaped furniture board decorative strip, and further includes the positioning tool for positioning the decorative strip as described above. The cutting tool is arranged at the end of the card slot of the positioning tool.
[0014] Furthermore, the cutting tool is an automatic cutting machine.
[0015] Furthermore, the automatic cutting machine includes a saw blade and a saw blade driving mechanism drivingly connected to the saw blade. The saw blade driving mechanism drives the saw blade to pass through the end of the card slot of the positioning tool to cut the decorative strip positioned on the positioning tool.
[0016] During cutting, the decorative strip is clamped onto the clamping seat at an angle where one side of the decorative part is outside and the other side is inside. The installation part of the decorative strip is inserted into the first card slot, and the inner side of the decorative part of the decorative strip is inserted into the second card slot. The decorative strip is positioned in this way, so as to reduce the swinging amplitude of the decorative strip and thus reduce the dimensional deviation at the cutting position.
[0017] In the clamped state of the decorative strip, the degree of dimensional matching between the decorative part of the decorative strip and the second card slot determines whether there are card joints with dimensional matching between the decorative strip and the second card slot. Since the thickness of the decorative part of the decorative strip is smaller than that of the installation part, correspondingly, the tolerance during processing is also relatively small. Therefore, the degree of dimensional matching between the decorative part and the second card slot is relatively high. Then, the decorative part of the decorative strip serves as the card joint with dimensional matching between the decorative strip and the second card slot, and the decorative strip is firmly clamped on the second card slot by this means, that is, the positioning effect of the card seat on the decorative strip is relatively strong.

[0023] The following further elaborates on the present invention in detail in combination with specific implementation modes.
[0024] The T-shaped furniture board decorative strip cutter is shown in Figure 1 , Figure 2, including the existing automatic cutting machine 4. The left wall 40 of the automatic cutting machine 4 is provided with two front and rear saw blade slots 401 and 402. Two front and rear circular saw blades 41 and 42 are respectively hidden in the two front and rear saw blade slots 401 and 402. The automatic cutting machine 4 is provided with a saw blade driving mechanism (not shown in the figure), and the saw blade driving mechanism is drivingly connected to the two front and rear saw blades 41 and 42. A front T-shaped furniture board decorative strip cutting positioning tool 10 is provided at the rear side of the front saw blade slot 401, and a rear T-shaped furniture board decorative strip cutting positioning tool 20 is provided at the front side of the rear saw blade slot 402. The automatic cutting machine 4 is used as a cutting tool to cut the T-shaped furniture board decorative strip 5. During cutting, the decorative strip 5 is placed horizontally, and its front part 55 and rear part 56 respectively pass through the positions of the front and rear saw blade slots 401 and 402. The two sets of front and rear cutting positioning tools 10 and 20 respectively position the front part 55 and rear part 56 of the decorative strip 5. The saw blade driving mechanism drives the two front and rear saw blades 41 and 42 to rotate around their respective centers, and drives the two front and rear saw blades 41 and 42 to move leftward respectively, so as to respectively extend out from the two front and rear saw blade slots 401 and 402, and respectively cut the front part 55 and rear part 56 of the decorative strip 5.
[0025] The two front and rear cutting positioning tools 10 and 20 have the same structure. The following takes the front cutting positioning tool 10 as an example for detailed description:
[0026] See Figure 1 , the cutting positioning tool 10 includes a clamping seat 1 and a support frame 6. The top of the support frame 6 is located above the clamping seat 1, and a cylinder 3 is installed thereon. The driving shaft 31 of the cylinder 3 faces downward, and a pressing block 2 is installed at the bottom. The clamping seat 1 is shown in Figure 5 , the top is provided with a first card slot 11 in the front-rear direction. The cross-section of the first card slot 11 is rectangular, and a second card slot 12 in the front-rear direction is opened at the left edge of the slot bottom of the first card slot 11. The cross-section of the second card slot 12 is also rectangular. The width L1 of the first card slot 11 is 4 - 5 mm, and the depth H1 is 2.5 - 4.5 mm. Preferably, L1 is 4.6 mm and H1 is 4 mm. The width L2 of the second card slot 12 is 0.5 - 1.5 mm, and the depth H2 is 0.5 - 1.5 mm. Preferably, L2 is 1 mm and H2 is 1 mm. The front and rear ends of the card slots 11 and 12 are open.
[0027] See Figure 5, the slot openings 115 and 125 of the card slots 11 and 12 of the card holder 1 face upward and are close to the outside world. Therefore, the upper sides of the card slots 11 and 12 are the outside, and correspondingly, the lower sides are the inside. The decorative strip 5 is placed at an angle with one side of the decorative part 52 facing outward and the other side facing inward. Its front part 55 is snap-fitted and installed into the card holder 1 of the cutting and positioning tool 10 from top to bottom. Specifically: the inner side 521 of the decorative part 52 is snapped into the second card slot 12, the installation part 51 is snapped into the first card slot 11, and the outer side 522 of the decorative part 52 is accommodated in the first card slot 11. The front part 55 of the decorative strip 5 is positioned in this way, so that the swing amplitude of the front part 55 of the decorative strip 5 can be reduced, thereby reducing the dimensional deviation of the cutting part 500 (see Figure 4 ). See Figure 1 , Figure 5 . After the decorative strip 5 is positioned, the air cylinder 3 serves as a driving mechanism to drive the pressing block 2 downward close to the card holder 1 until the pressing block 2 presses the front part 55 of the decorative strip 5 and the card holder 1 inward from the outside of the slot opening 115 of the first card slot 11, enhancing the positioning effect of the front part 55 of the decorative strip 5 and preventing the front part 55 of the decorative strip 5 from swinging vertically and slipping out of the first and second card slots 11 and 12 due to external forces; in this state, the card holder 1 also serves as a limiting block to limit the pressing block 2 to prevent the pressing block 2 from deforming the decorative strip 5 due to excessive downward pressing. See Figure 3 , Figure 4 . The front part 55 of the decorative strip 5 extends out to the outside from the front and rear ends of the card slots 11 and 12. The front saw blade slot 401 of the automatic cutting machine 4 is located at the front ends 111 and 121 of the first and second card slots 11 and 12. During cutting, the front saw blade 41 extends leftward from the front saw blade slot 401 and passes through the front ends 111 and 121 of the first and second card slots 11 and 12, and cuts the front part 55 of the decorative strip 5 as shown in Figure 2 . The part of the front part 55 of the decorative strip 5 located behind the cutting part 500 sees Figure 4 , and is just snap-fitted in the card holder 1, and this part is not easy to swing during cutting.
[0028] See Figure 5 . When the decorative strip 5 is in the snap-fitted state, the degree of dimensional matching between the decorative part 52 of the decorative strip 5 and the second card slot 12 determines whether there is a dimensionally matching snap point between the decorative strip 5 and the second card slot 12. Since the thickness of the decorative part 52 of the decorative strip 5 is smaller than that of the installation part 51, correspondingly, the processing tolerance is also relatively small. Therefore, the degree of dimensional matching between the decorative part 52 and the second card slot 12 is relatively high. Then, the decorative part 52 of the decorative strip 5 serves as the dimensionally matching snap point between the decorative strip 5 and the second card slot 12, and the decorative strip 5 is firmly snap-fitted on the second card slot 12 by this means, that is, the card holder 1 has a strong positioning effect on the decorative strip 5.
[0029] See Figure 1, the subsequent cutting and positioning tool 20 has the same structure as the preceding cutting and positioning tool 10, which will not be elaborated. The rear part 56 of the decorative strip 5 is clamped and installed on the clamping seat 1 of the subsequent cutting and positioning tool 20 in the same manner, which will not be elaborated.
[0030] In other embodiments, an existing manual cutting tool can be used to replace the automatic cutting machine 4 to cut the decorative strip 5.
[0031] See Figure 1 , Figure 4 , in other embodiments, the front and rear saw blades 41 and 42 of the automatic cutting machine 4 can be changed to be arranged between the front and rear cutting and positioning tools 10 and 20 to cut the middle part of the decorative strip 5. Specifically: the front saw blade groove 401 is located at the rear end parts of the clamping grooves 11 and 12 of the preceding clamping seat 1, and the front saw blade 41 passes through the rear end parts of the clamping grooves 11 and 12 of the preceding clamping seat 1 to cut the middle part of the decorative strip 5; the rear saw blade groove 402 is located at the front end part of the clamping groove of the subsequent clamping seat 1, and the rear saw blade 42 passes through the front end part of the clamping groove of the subsequent clamping seat 2 to cut the middle part of the decorative strip 5.
[0032] As described above, it is only the implementation mode of the present invention, and the patent protection scope is not limited thereby. Those skilled in the art make non-substantive changes or substitutions based on the present invention, and still fall within the patent protection scope.
