Description

Technical Field

[0001] This utility model relates to the technical field of furniture processing, specifically to a furniture edge grinding machine. Background Technology

[0002] The contour grinding machine is mainly used for processing irregularly shaped edges of furniture boards, such as MDF, particleboard, and solid wood panels. Its core principle is to control the path of the grinding tool through a precisely manufactured template, thereby mass-producing identical irregularly shaped edges.

[0003] A contour grinding machine mainly consists of a rotary table, a clamping system, a contouring system (template system), a grinding head system, a control system, and auxiliary systems. The contouring system typically includes pulleys mounted on the grinding head system and a plate-shaped mold mounted on the rotary table. During processing, the clamping system fixes the sheet metal to the upper surface of the plate-shaped mold. The grinding head system includes a rotating milling cutter. The position of the milling cutter and the pulleys is relatively fixed. The milling cutter moves closer to the sheet metal until the pulleys contact the edge of the plate-shaped mold. The rotary table rotates the plate-shaped mold and the sheet metal one revolution, with the pulleys always maintaining contact with the edge of the plate-shaped mold, thus completing the edge grinding of the sheet metal. The auxiliary system generally includes a dust removal system. The control system typically includes an electrical control cabinet and an operation panel. The electrical control cabinet includes electrical components such as a PLC controller, frequency converter, contactor, and circuit breaker.

[0004] However, existing contour grinding machines still have the following shortcomings. In order to improve the utilization rate of the board, when the board is initially cut, it will be cut into a preliminary product with a shape similar to the board mold. The smaller the shape difference between the preliminary product and the board mold, the higher the material utilization rate during the overall board layout. Therefore, when placing the preliminary product on the board mold, there are certain positioning requirements for the placement of the board to avoid gaps on the edges of the processed product after it is placed crookedly. In the existing technology, it is necessary to adjust it manually after placement, which requires the operator's experience to adjust the position of the board. This requires a high level of experience from the operator. Therefore, it is necessary to design a furniture grinding machine. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issue of material misalignment that occurs when manually placing the sheet material onto the sheet material mold in the prior art.

[0006] To achieve the above objectives, this utility model provides a furniture edge grinding machine, comprising: a rotary worktable, a base plate mounted on the rotating end of the rotary worktable, a plate-shaped mold detachably mounted on the base plate, a pressing clamp unit mounted on the rotary worktable, and an auxiliary positioning unit mounted on the lower surface of the base plate. The auxiliary positioning unit includes a horizontal sliding ring that is vertically slidably connected to the base plate, at least three positioning mechanisms that are spaced apart along the circumference of the sliding ring, and a hand control mechanism mounted on the sliding plate to drive the sliding ring to slide vertically. The positioning mechanism includes a horizontal telescopic rod whose length direction is consistent with the radial direction corresponding to the sliding ring, and a vertical positioning arm mounted on the end of the telescopic rod away from the sliding ring. The plate-shaped mold is located between several positioning arms.

[0007] Preferably, the upper end of the positioning arm is provided with an inclined wedge portion that is inclined away from the edge of the plate-shaped mold.

[0008] Preferably, the telescopic rod includes a horizontal strip sleeve fixedly connected to the sliding ring, a slide rod that slides into the strip sleeve in the same length direction, and a threaded locking bolt that is threaded onto the end of the strip sleeve away from the sliding ring and can abut against the slide rod; The strip sleeve has a first strip-shaped through groove of the same length direction. The end of the slide rod near the sliding ring is equipped with a limiting bolt that passes through the first strip-shaped through groove. The positioning arm is assembled on the end of the slide rod away from the limiting bolt.

[0009] Preferably, the bottom of the base plate is equipped with a plurality of vertical guide rods, and the sliding ring is slidably mounted on the guide rods; The hand control mechanism includes a mounting ring fixedly connected to the bottom of several guide rods, a control handle horizontally slidably mounted on the mounting ring, and a wedge block mounted on the control handle and located above the mounting ring. A second strip-shaped through groove with the same inclination angle as the inclination angle of the inclined surface of the wedge block is provided through the wedge block. A guide bolt that slides through the second strip-shaped through groove is mounted on the sliding ring.

[0010] Preferably, the pressing clamp unit includes a vertical pressing cylinder mounted on a rotary worktable and located directly above the rotating end of the rotary worktable, a vertical mounting rod mounted on the moving end of the pressing cylinder, a mounting seat coaxially mounted on the mounting rod via a bearing, and a pressing block mounted on the mounting seat via several first mounting bolts. The mounting rod is coaxially arranged with the rotating end of the rotary worktable.

[0011] Preferably, the plate mold is provided with a plurality of countersunk holes, and the plate mold is assembled on the base plate by a plurality of second mounting bolts passing through the corresponding countersunk holes.

[0012] According to the above technical solution, the furniture edge grinding machine provided by this utility model has the following beneficial effects during use: Firstly, when the board needs to be placed on the plate mold, the sliding ring is first driven to slide upward by the manual control mechanism, so that the upper end of the positioning arm is higher than the upper surface of the plate mold. The several upward-protruding positioning arms can position the board, improve the efficiency of board placement, and even those without experience can complete the board placement through the auxiliary positioning unit, reducing the experience requirements of the equipment. Secondly, after the sheet metal is pressed down by the pressure clamp unit, the sliding ring is moved downward by the manual control mechanism, so that the upper end of the positioning arm is lower than the lower surface of the sheet mold to avoid collision with the positioning arm. Thirdly, after changing to different plate molds, the length of each telescopic rod is adjusted so that each positioning arm maintains a suitable distance from the edge of the plate mold, thereby positioning different plates, which is highly practical.

[0013] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0016] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0017] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0018] like Figure 1-4 As shown, a furniture edge grinding machine is characterized by comprising: a rotary worktable 1, a base plate 2 mounted on the rotating end of the rotary worktable 1, a plate-shaped mold 3 detachably mounted on the base plate 2, a pressing clamp unit mounted on the rotary worktable 1, and an auxiliary positioning unit mounted on the lower surface of the base plate 2. The auxiliary positioning unit includes a horizontal sliding ring 4 that is vertically slidably connected to the base plate 2, at least three positioning mechanisms distributed at intervals along the circumference of the sliding ring 4, and a hand control mechanism mounted on the sliding plate for driving the sliding ring 4 to slide vertically. The positioning mechanism includes a horizontal telescopic rod 5 whose length direction is consistent with the radial direction corresponding to the sliding ring 4, and a vertical positioning arm 6 mounted on the end of the telescopic rod 5 away from the sliding ring 4. The plate-shaped mold 3 is located between several positioning arms 6.

[0019] In the above technical solution, the edge grinding machine head system is an existing mature technology, so it is not shown in the figure. The edge grinding machine head system includes a base, a slide that can be slidably mounted on the base and can move close to the plate mold 3, a motor mounted on the slide, a milling cutter mounted on the output shaft of the motor, and the pulley in the contouring system is also mounted on the slide. When the sheet material needs to be placed on the plate mold 3, the sliding ring 4 is first moved upward by the manual control mechanism, which in turn moves the telescopic rod 5 and the positioning arm 6 upward, so that the upper end of the positioning arm 6 is higher than the upper surface of the plate mold 3. The upward protruding positioning arms 6 can position the sheet material, which not only improves the efficiency of sheet material placement, but also allows even those without experience to complete the placement of the sheet material through the auxiliary positioning unit, improving the quality and efficiency of processing and reducing the experience requirements of the equipment. After the sheet metal is pressed down by the pressure clamp unit, the sliding ring 4 is moved downward by the manual control mechanism, which in turn moves several positioning arms 6 downward so that the upper end of the positioning arm 6 is lower than the lower surface of the plate mold 3. Since the pulley needs to be in contact with the side wall of the plate mold 3, the lowered positioning arm 6 can make room for the cooperation between the pulley and the plate mold 3. Otherwise, the positioning arm 6 will collide with the pulley. After replacing different plate molds 3, the length of each telescopic rod 5 is adjusted so that each positioning arm 6 maintains a suitable distance from the edge of the plate mold 3, thereby positioning different plates, which is highly practical.

[0020] In a preferred embodiment of the present invention, the upper end of the positioning arm 6 is provided with an inclined wedge 7 that is inclined away from the edge of the plate mold 3.

[0021] In the above technical solution, the wedge 7 is provided to facilitate the placement of the plate between several positioning arms 6.

[0022] In a preferred embodiment of this utility model, the telescopic rod 5 includes a horizontal strip sleeve 8 fixedly connected to the sliding ring 4, a slide rod 9 slidably inserted into the strip sleeve 8 in the same length direction, and a locking bolt 10 threadedly assembled at the end of the strip sleeve 8 away from the sliding ring 4 and able to abut against the slide rod 9. The strip sleeve 8 has a first strip groove 11 of the same length direction. The end of the slide rod 9 near the sliding ring 4 is equipped with a limiting bolt 12 that passes through the first strip groove 11. The positioning arm 6 is assembled on the end of the slide rod 9 away from the limiting bolt 12.

[0023] In the above technical solution, by loosening the locking bolt 10, the slide rod 9 can slide with the strip sleeve 8, thereby adjusting the length of the telescopic rod 5 and adjusting the distance between the positioning arm 6 and the edge of the plate mold 3. Then, by tightening the locking bolt 10, the strip sleeve 8 and the slide rod 9 are fixed together. The limiting bolt 12 and the first strip through groove 11 can prevent the slide rod 9 from separating from the strip sleeve 8 when it is adjusted.

[0024] In a preferred embodiment of this utility model, the bottom of the base plate 2 is equipped with a plurality of vertical guide rods 13, and the sliding ring 4 is slidably mounted on the guide rods 13. The hand control mechanism includes a mounting ring 14 fixedly connected to the bottom end of several guide rods 13, a control handle 15 horizontally slidably mounted on the mounting ring 14, and a wedge block 16 mounted on the control handle 15 and located above the mounting ring 14. A second strip-shaped through groove 17 with the same inclination angle as the inclined surface of the wedge block 16 is provided through the wedge block 16. A guide bolt 18 that slides through the second strip-shaped through groove 17 is mounted on the sliding ring 4.

[0025] In the above technical solution, the wedge block 16 is moved by controlling the handle 15. When the guide bolt 18 slides downward in the second through groove 17, it will drive the sliding ring 4 to slide downward on several guide rods 13. At this time, the sliding ring 4 will not rise without the action of external force. When the guide bolt 18 slides upward in the second through groove 17, it will drive the sliding ring 4 to slide upward on several guide rods 13, thereby moving the positioning arm 6 upward.

[0026] In a preferred embodiment of the present invention, the pressing clamp unit includes a vertical pressing cylinder 19 mounted on a rotary worktable 1 and located directly above the rotating end of the rotary worktable 1, a vertical mounting rod 20 mounted on the moving end of the pressing cylinder 19, a mounting seat 21 coaxially mounted on the mounting rod 20 via a bearing, and a pressing block 22 mounted on the mounting seat 21 via a plurality of first mounting bolts. The mounting rod 20 is coaxially arranged with the rotating end of the rotary worktable 1.

[0027] In the above technical solution, the pressing cylinder 19 can drive the pressing block 22 to move downward and press it onto the plate. The mounting rod 20 is coaxially arranged with the rotating end of the rotating worktable 1. When the rotating worktable 1 drives the plate mold 3 to rotate, it will drive the pressing block 22 and the mounting base 21 to rotate together.

[0028] In a preferred embodiment of this utility model, the plate mold is provided with a plurality of countersunk holes, and the plate mold is assembled on the base plate 2 by a plurality of second mounting bolts passing through the corresponding countersunk holes.

[0029] In the above technical solution, by loosening and removing several second mounting bolts, the plate mold 3 can be removed from the base plate 2 and replaced with a different plate mold 3.

[0030] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0031] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0032] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
