Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture board processing technology, specifically to a positioning fixture for furniture board processing. Background Technology
[0002] Before processing furniture panels, such as before drilling, a positioning fixture is needed to position the panels. This fixture consists of two horizontally aligned clamps with a space between them for the furniture panel. The panel is placed in this space, and the fixture's drive mechanism moves the two clamps together to horizontally clamp the panel, thus achieving positioning. However, the edges of furniture panels are prone to warping under external forces or temperature changes. Existing positioning fixture designs only provide lateral clamping force, leaving the edges of the panel still warped after clamping, which can affect processing. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a positioning fixture for furniture board processing, which can improve the warping phenomenon at the edge of the furniture board after the positioning fixture clamps the furniture board laterally.
[0004] To solve the above-mentioned technical problems, the positioning fixture for furniture board processing of this utility model includes a placement seat, on which are arranged first and second clamps in parallel. The inner sides of the first and second clamps have longitudinal placement positions for vertical furniture boards to be placed and then placed on the placement seat. The first and second clamps together laterally clamp the furniture board that has been placed in the furniture board placement position. The inner surface of the first clamp has a sloping area that is inclined towards the placement seat. The first clamp moves laterally inward from the sloping area to apply pressure towards the placement seat to the first edge of the furniture board, thereby flattening the first edge of the furniture board.
[0005] Furthermore, the first and second clamps are staggered longitudinally.
[0006] Furthermore, there are two second chucks arranged longitudinally side by side, with a gap between the two second chucks, and the first chuck is aligned with this gap; and / or
[0007] The first chuck has at least two longitudinally arranged chucks with a gap between them, and the second chuck is aligned with this gap.
[0008] Furthermore, the second clamp has a pressure block extending from the top of the first clamp, and the second clamp includes a pressure plate mechanism that drives the pressure block to move closer to the placement seat, thereby applying pressure toward the placement seat to the second edge portion of the furniture board opposite to the first edge portion.
[0009] Furthermore, it includes a drive mechanism that drives the first and second clamps to move inward together to clamp the furniture board that has been placed in the furniture board placement position.
[0010] Furthermore, the mounting base has a slot facing the longitudinal placement position, and the drive mechanism is installed in the mounting slot.
[0011] Taking the first and second clamps located on the upper side of the placement base as an example: In use, the furniture board is placed from top to bottom into the furniture board placement position inside the first and second clamps and then placed on the placement base. The first and second clamps clamp the furniture board that has been placed in the furniture board placement position laterally. In this state, the first clamp moves laterally inward from the inclined area on the inner surface to apply downward pressure to the first edge of the furniture board, which can flatten the first edge of the furniture board and thus improve the warping phenomenon of the first edge of the furniture board.

[0015] The present invention will be further described in detail below with reference to specific embodiments.
[0016] Furniture board positioning device (see) Figure 1 Two positioning units 71 and 72 are installed on the base 6. Each positioning unit 71 and 72 includes three positioning clamps 8: front, middle, and rear. The front-to-back direction is longitudinal, and the left-to-right direction is transverse. The three positioning clamps 8 are arranged longitudinally side by side, and the two positioning units 71 and 72 are arranged transversely side by side. Two longitudinal furniture panels 901 and 902 are placed on the left and right positioning units 71 and 72 respectively. The three positioning clamps 8 of the left positioning unit 71 clamp the front, middle, and rear parts of the left furniture panel 901, thereby positioning the furniture panel 901. The three positioning clamps 8 of the right positioning unit 72 also clamp the front, middle, and rear parts of the right furniture panel 902, thereby positioning the furniture panel 902. After the furniture panels 901 and 902 are positioned, they can be drilled. In this embodiment, the furniture panels 901 and 902 are both door panels. Since the left and right positioning units 71 and 72 are symmetrical in structure, and the front, middle and rear three positioning fixtures 8 of each of the left and right positioning units 71 and 72 are identical in structure, the following detailed description will take one of the positioning fixtures 8 of the left positioning unit 71 as an example:
[0017] Positioning clamp 8 (see) Figure 2 Includes a placement seat 1, which is fixedly installed on the base 6 (see...). Figure 1On the left end of the mounting base 1, there are two longitudinally parallel left clamps 27 with identical structures, one in front and one behind. Each left clamp 27 includes a left clamping block 271 mounted on the mounting base 1 and an electric push rod 272. The electric push rod 272 is located to the left of the left clamping block 271, with its rod body 273 extending upward above the left clamping block 271 and mounting a pressure block 275. The pressure block 275 extends to the right to the right of the left clamping block 271. The mounting base 1 has a left-right oriented mounting groove 10, in which a cylinder 23 is installed. The cylinder 23 drives the rod 231 to extend to the right and mounts a right clamp 28. The upper half of the left surface 280 of the right clamp 28 is an inclined downward slope area 281, located above the mounting base 1. The left and right chucks 27 and 28 are arranged side by side horizontally, with longitudinal placement positions 20 on their inner sides. The left surface 280 of the right chuck 28 faces the longitudinal placement positions 20 on the inner sides of the left and right chucks 27 and 28, so this surface is the inner surface. A gap 270 is left between the two left chucks 27, and the right chuck 28 is aligned with this gap 270. The opening of the mounting slot 10 faces the gap 270 and the longitudinal placement positions 20.
[0018] Use positioning fixture 8 to position furniture board 901, see Figure 3 First, place the furniture board 901 into the longitudinal placement position 20 and then flatten it on the placement seat 1. Then, control the cylinder 23 to drive the rod 231 to retract to the left. That is, use the cylinder 23 as the driving mechanism to drive the right clamp 28 to move to the left and closer to the left clamp 27, so that the left and right clamps 27 and 28 move laterally inward until the left and right clamps 27 and 28 together laterally clamp the furniture board 901 in the longitudinal placement position 20. The right clamp 28 moves laterally to the left from the inclined area 281, pushing the right edge 91 of the furniture board 901 downward, applying a leftward pushing force and downward pressure to the right edge 91 of the furniture board 901. If the right edge 91 of the furniture board 901 is warped, the inclined area 281 of the right clamp 28 can press the right edge 91 of the furniture board 901 downward flat, thereby improving the warping of the right edge 91 of the furniture board 901. After the left and right clamps 27 and 28 clamp the furniture board 901 together, the electric push rod 272 is controlled to retract downwards. That is, the electric push rod 272 acts as a pressure plate mechanism, driving the pressure block 275 of the left clamp 27 to apply downward pressure to the left edge 92 of the furniture board 901. If there is warping on the left edge 92 of the furniture board 901, the pressure block 275 of the left clamp 27 can press the left edge 92 of the furniture board 901 downwards to flatten it, thereby improving the warping of the left edge 92 of the furniture board 901.
[0019] See Figure 1Since the left and right positioning units 71 and 72 are symmetrical in structure, and the front, middle, and rear three positioning fixtures 8 of each of the left and right positioning units 71 and 72 have the same structure, other positioning fixtures will not be described in detail in this embodiment. The two front positioning fixtures 8 share the same placement seat 1, the two middle positioning fixtures 8 also share the same placement seat 1, and the two rear positioning fixtures 8 are also like this.
[0020] This embodiment is shown in Figure 2 , Figure 3 Each positioning clamp 8 in the positioning device is a three-point positioning clamp, meaning the left and right clamps 27 and 28 are staggered front and back, working together to laterally clamp the furniture board 901. Therefore, even if the clamps 27 and 28 are relatively short, they can still achieve stable positioning of the furniture board 901. The short clamps 27 and 28 are lightweight and can be driven by a low-power, small-volume cylinder 23. In a non-preferred embodiment, a two-point positioning clamp can be used, where the left and right clamps are directly aligned and work together to laterally clamp the furniture board. However, this would require the clamps to be designed to be as long as possible to ensure positioning effectiveness, resulting in heavier clamps that would need to be driven by a higher-power, larger-volume cylinder.
[0021] See other embodiments. Figure 2 , Figure 3 The left clamp 27 can be modified to be symmetrical to the right clamp 28. When the left and right clamps 27 and 28 clamp the furniture board 901 laterally, the inclined area of the left clamp 27 (see the inclined area 281 of the right clamp 28) applies a rightward pushing force and a downward pressure to the left edge 92 of the furniture board 901.
[0022] See other embodiments. Figure 2 , Figure 3 The left and right chucks 27 and 28 can be swapped or a right chuck 28 can be added directly. The two right chucks 28 are arranged longitudinally in front and behind. Correspondingly, the mounting groove 10 has two parallel grooves in front and behind, and the cylinder 23 has two parallel grooves in front and behind. A gap is left between the two right chucks 28, and a left chuck 27 is aligned with the gap.
[0023] In this embodiment, furniture panels 901 and 902 are both door panels. Other embodiments can be replaced with other furniture panels, such as cabinet panels.
[0024] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
