Description

Technical Field

[0001] This utility model relates to building panel processing machinery, and in particular to a synchronous milling machine for side tenon grooves of lightweight composite wall panels. Background Technology

[0002] With the continuous expansion of the application fields of prefabricated building structures, precast lightweight cement composite wall panels, as an important non-load-bearing or self-supporting enclosure wall material, are widely used due to their excellent thermal insulation, fire resistance, and sound insulation properties. Especially in projects such as subway equipment rooms, lightweight cement composite wall panels, with their lightweight, high strength, excellent fire resistance, and rapid assembly characteristics, are gradually replacing masonry methods and driving the innovation of subway auxiliary building technology.

[0003] To meet the needs of rapid, accurate, and reliable on-site installation, and to further improve the integrity, precision, and seismic performance of the wall, a tongue-and-groove joint installation method is adopted at the splicing of adjacent wall panels. For example, a precast lightweight cement composite wall panel used in a subway system uses calcium silicate board for the wall panel face and side panels, with cement polystyrene particle core material wrapped inside. The specific process is to attach the calcium silicate board to the mold, place a three-dimensional fiber mesh, and then pour cement polystyrene particle core material into the mold to form a precast lightweight cement composite wall panel. Then, the long side panels of the precast lightweight cement composite wall panel are further processed and milled to create tongues or grooves.

[0004] However, in practice, since the parts need to be fixed in the fixture on the milling machine during milling, there is no suitable milling machine available for the aforementioned large-sized precast lightweight cement composite wall panels. The existing method is to place them in a precision machining center for milling, which results in high processing costs and low efficiency, making it difficult to meet the needs of large-scale industrial production.

[0021] To better understand the side milling equipment, let's first introduce the specific structure of the wall panel 400, such as... Figure 3 , 4 As shown, the wall panel 400, after molding, comprises a cement-polystyrene particle core material 410 and an outer calcium silicate board 420. The calcium silicate board 420 surrounds the outer periphery of the cement-polystyrene particle core material 410, and the top and bottom surfaces of the cement-polystyrene particle core material 410 are not covered. The side milling equipment of this application is used to mill the long sidewalls of the wall panel 400 to form tenon and / or tongue structures.

[0022] Working principle: The wall panel 400 is placed on the conveying device 200, which drives the wall panel 400 to move. After moving to the designated position, the wall panel 400 is fixed by the positioning device 300. After the milling device 500 moves to the predetermined position, it performs milling processing on the side walls on both sides of the wall panel 400.

[0023] like Figure 1 As shown, a conveying device 200 and two milling devices 500 are mounted on the equipment base assembly 100.

[0024] Specifically, such as Figure 5 As shown, the equipment base assembly 100 includes a fixed base 110, on which a first longitudinal moving base 120 and several transverse moving bases 140 are connected. A second longitudinal moving base 130 is slidably connected to each of the transverse moving bases 140, and the second longitudinal moving base 130 is arranged parallel to the first longitudinal moving base 120. A milling device 500 is connected to the first longitudinal moving base 120, and the milling device 500 can move back and forth with the first longitudinal moving base 120. Another milling device 500 is connected to the second longitudinal moving base, and the milling device 500 can move in both forward / backward and left / right directions with the second longitudinal moving base and the several transverse moving bases 140. Several lateral moving bases 140 are located at the end away from the second longitudinal moving base 130 and are also connected to a support assembly 210. A conveying device 200 and a waste collection device 600 are connected to the support assembly 210. The conveying device 200 and the waste collection device 600 can move left and right with the lateral moving bases 140. In this embodiment, the number of lateral moving bases 140 is three.

[0025] More specifically, the fixed base 110 is composed of several steel sections welded together with reinforcing ribs.

[0026] The first longitudinal moving base 120 can drive the milling device 500 on the left to move synchronously. Specifically, as shown... Figure 1 , 2 As shown in Figure 5, the first longitudinal moving base 120 includes a first longitudinal base frame 121, a first slide rail slider assembly 122, a first moving transmission mechanism 123, and a first moving drive unit 124. The slide rail of the first slide rail slider assembly 122 is connected to the first longitudinal base frame 121, and the slider of the first slide rail slider assembly 122 is connected to the milling device 500 on the right side. The first moving drive unit 124 is fixedly installed on the milling device 500, and the first moving drive unit 124 drives the milling device 500 to move through the first moving transmission mechanism 123.

[0027] The second longitudinal moving base 130 can drive the milling device 500 on the right side to move synchronously. Specifically, such as... Figure 1 , 2 As shown in Figure 5, the second longitudinal moving base 130 includes a second longitudinal moving base frame 131, a second slide rail slider assembly 132, a second moving transmission mechanism 133, and a second moving drive unit 134. The slide rail of the second slide rail slider assembly 132 is fixedly connected to the second longitudinal moving base frame 131, and the slider of the second slide rail slider assembly 132 is connected to the milling device 500 on the left. The second moving drive unit 134 is fixedly installed on the milling device 500, and the second moving drive unit 134 drives the milling device 500 to move through the second moving transmission mechanism 133.

[0028] The lateral moving base 140 can drive the second longitudinal base to move 130, thereby driving the milling device 500 on the right side to move synchronously. Specifically, as shown... Figure 1 , 2 As shown in Figure 5, the transverse moving base 140 includes a transverse base frame 141, a third slide rail slider assembly 142, a third moving transmission mechanism 143, and a third moving drive unit 144. The slide rail of the third slide rail slider assembly 142 is fixedly connected to the second longitudinal base frame 131, and the slider of the third slide rail slider assembly 142 is fixedly connected to the transverse base frame 141. The third moving drive unit 144 is fixedly installed on the transverse base frame 141, and the third moving drive unit 144 drives the second longitudinal moving base 130 to move through the third moving transmission mechanism 143.

[0029] The lateral moving base 140 can drive the conveying device 200 and the waste collection device 600 to move synchronously. Specifically, for example... Figure 1 , 5As shown in Figure 6, the transverse moving base 140 also includes a fourth slide rail slider assembly 145, a fourth moving transmission mechanism 146, and a fourth moving drive unit 147. The slide rail of the fourth slide rail slider assembly 145 is connected to the transverse base frame 141 and the support assembly 210. The fourth moving drive unit 147 is fixedly installed on the transverse base frame 141. The fourth moving drive unit 147 drives the support assembly 210 to move through the fourth moving transmission mechanism 146, and simultaneously drives the conveying device 200 and the waste collection device 600 to move.

[0030] like Figure 6 As shown, in this embodiment, the third slide rail slider assembly 142 and the fourth slide rail slider assembly 145 share a single slide rail slider assembly.

[0031] In this embodiment, the first moving transmission mechanism 123 and the second moving transmission mechanism 133 are both configured as gear and rack mechanisms, the third moving transmission mechanism 143 and the fourth moving transmission mechanism 146 are both configured as lead screw and nut mechanisms, and the first moving drive unit 124, the second moving drive unit 134, the third moving drive unit 144 and the fourth moving drive unit 147 are all configured as motors.

[0032] like Figure 7 , 8 As shown, in this embodiment, the conveying device 200 is a belt conveyor.

[0033] like Figure 7 , 8 As shown, a positioning device 300 is installed on the bracket assembly 210. The positioning device 300 is located inside the belt conveyor, that is, between two parallel belts, and is used to fix the wall panel 400.

[0034] Specifically, such as Figure 7 , 8 The positioning device 300 shown includes an adsorption fixing part 310 and an adsorption driving part 320. The adsorption fixing part 310 includes several vacuum pumps 311 and several suction cups 312. The vacuum suction cups 312 are connected to the support assembly 210 by leveling bolts 313 to ensure that the suction cups 312 are at the same height as the top surface of the conveyor belt. The adsorption driving part 320 provides power to the several vacuum pumps 311, and the vacuum pumps 311 provide adsorption force to the suction cups 312. In this embodiment, the adsorption driving part 320 is a motor. Figure 3 As shown, in this embodiment, four suction cups 312 are used as an example, and four vacuum pumps 311 are used.

[0035] The milling device 500 is used to mill tenons or grooves into the long sidewall of the wall panel 400. For example... Figure 1 , 2As shown, there are two milling devices 500, located on both sides of the conveying device 200. One is used to mill a tenon structure on the long side wall of the wall panel 400, and the other is used to mill a groove structure on the long side wall of the wall panel 400. The two milling devices 500 are respectively mounted on the first longitudinal moving base 120 and the second longitudinal moving base 130, and can move synchronously with the first and second longitudinal moving bases respectively.

[0036] Furthermore, such as Figure 9 , 10 As shown, the milling device 500 includes a frame 510, a first lifting part 520, a tenon / groove tool mechanism 530, a second lifting part 540, and a trimming tool mechanism 550.

[0037] Specifically, the frame 510 includes a receiving platform 511 at the bottom and a frame 512 fixedly mounted on the receiving platform 511. The frame 512 includes three vertically arranged adjacent sides and a top surface. A first lifting unit 520 is mounted on the side of the frame 512 closest to the conveying device 200 and is capable of vertical movement. In this embodiment, the first lifting unit 520 includes a first motor 521 and a first lead screw and nut mechanism 522 connected together. A tenon / concave tenon cutting mechanism 530 is mounted on the first lead screw and nut mechanism 522. The first motor 521 drives the first lead screw and nut mechanism 522 to move vertically, and the first lead screw and nut mechanism 522 drives the tenon / concave tenon cutting mechanism 530 to move synchronously.

[0038] To ensure the linear motion of the tenon / parietal tool mechanism 530, a first guide part 560 is also installed on the milling device 500. In this embodiment, the first guide part 560 adopts a slide rail slider structure. The fixed end of the slide rail slider structure is fixed on the frame 512, and the movable end of the slide rail slider structure is connected to the tenon / parietal tool mechanism 530.

[0039] The tenon / grooving tool mechanism 530 includes a vertical cutter head 531, a first tool body 532, a first tool transmission mechanism 533, and a first tool drive device 534. The vertical cutter head 531 is detachably mounted on the first tool body 532, which is mounted on a first lifting part 520. The first tool drive device 534 is connected to the first tool body 532 via a first tool rotation mechanism to drive the vertical cutter head 531 to rotate around an axis. In this embodiment, the first tool transmission mechanism 533 is always a belt drive mechanism, and the first tool drive device 534 is always a servo motor.

[0040] like Figure 11 , 12As shown, specifically, the vertical cutter head 531 includes a first connecting portion 5311 connected to the first cutter body 532 and a first working portion 5312 integrally connected to the first connecting portion 5311. The first working portion 5312 is circumferentially provided with a structure adapted for milling tenons or grooves. That is, there are two types of vertical cutter heads 531, one is a tenon milling cutter head (see...). Figure 11 Another type is the concave tenon end mill head (see...) Figure 12 The structures are basically the same, with the only difference being the structure of the first working part 5312.

[0041] The second lifting part 540 is installed on either of the other two parallel sides of the frame 512 and is capable of moving up and down. In this embodiment, the second lifting part 540 includes a connected second motor 541 and a second lead screw and nut mechanism 542. A trimming tool mechanism 550 is installed on the second lead screw and nut mechanism 542. The second motor 541 drives the second lead screw and nut mechanism 542 to move up and down, and the second lead screw and nut mechanism 542 drives the trimming tool mechanism 550 to move synchronously.

[0042] To ensure the linear motion of the trimming tool mechanism 550, a second guide part 570 is also installed on the milling device 500. In this embodiment, the second guide part 570 adopts a slide rail slider structure. The fixed end of the slide rail slider structure is fixed on the frame 512, and the movable end of the slide rail slider structure is connected to the trimming tool mechanism 550.

[0043] The trimming tool mechanism 550 is connected to the second lifting part 540 and can move synchronously with the second lifting part 540. For example... Figure 13 As shown, the trimming tool mechanism 550 includes a horizontal cutter head 551, a second tool body 552, a second tool transmission mechanism 553, and a second tool drive device 554. The horizontal cutter head 551 is detachably mounted on the second tool body 552, which is mounted on the first lifting part 520. The second tool drive device 554 is connected to the second tool body 552 via a second tool rotation mechanism to drive the horizontal cutter head 551 to rotate around an axis. In this embodiment, the second tool transmission mechanism 553 is always a belt drive mechanism, and the second tool drive device 554 is always a servo motor. Before processing the wall panel 400, the trimming tool mechanism 550 can also be used to fine-tune its left and right positions so that the side of the wall panel 400 is parallel to the direction of movement of the conveying device, thereby ensuring processing accuracy. In summary, the trimming tool mechanism 550 can not only perform trimming and milling on the side of the wall panel, but also, in conjunction with the positioning device 300, replace the clamping setting required by conventional machinery, exhibiting good stability and adjustability.

[0044] Specifically, such as Figure 14As shown, the horizontal cutter head 551 includes a second connecting part 5511 connected to the second cutter body 552 and a second working part 5512 integrally connected to the second connecting part 5511. The second working part 5512 is provided with a structure in the circumferential direction for trimming the long side edge of the wall panel 400.

[0045] The waste collection device 600 is used to collect milling debris. It is located between the conveying device 200 and the milling device 500. It is connected to the transverse moving base 140 through the support assembly 210 and can move synchronously with the transverse moving base 140. In this embodiment, there are two waste collection devices 600, which are fixedly installed on the left and right sides of the support assembly 210.

[0046] More specifically, in this embodiment, the waste collection device 600 includes a waste trough 610 fixedly installed on the equipment base 100. The waste trough 610 is equipped with a fully automatic spraying device, which can effectively reduce dust pollution during the cutting process and improve the operating accuracy of the milling cutter equipment.

[0047] like Figure 15 The working process of a milling machine is as follows: Step 1, rough adjustment of milling cutter equipment: According to the width of the wall panel 400, the transverse moving base 140 and the conveying device 200 move synchronously with the second longitudinal moving base 130, so that the wall panel 400 is basically located in the middle of the side milling equipment and the positioning device 300. Step 2, Wall panel leveling and positioning: Wall panel 400 enters the working area of ​​the side milling equipment through the conveying device 400 and positioning device 300. After positioning, fine-tune the leveling bolts 313 to make the wall panel 400 horizontal. Step 3, Alignment of Wall Panel Left and Right: Install the corresponding vertical cutter head 531 and horizontal cutter head 551 according to the wall panel production requirements. One side of the vertical cutter head 531 adopts a concave tenon cutter structure, and the other side of the vertical cutter head 531 adopts a convex tenon cutter structure. Move the milling device 500 to both sides of the wall panel 400. By moving the horizontal moving base 140, the horizontal cutter head 551 is driven to correct the left and right offset position of the wall panel 400. Activate the adsorption drive unit 320 to achieve point-to-point adsorption between several vacuum suction cups 312 and the wall panel 400. Step 4, Milling cutter return to position: Start the first longitudinal moving device 120 and the second longitudinal moving device 130 to move the milling device 500 to the starting position of the edge of the wall panel 400, with the horizontal cutter head 551 corresponding to the bottom of the wall panel; Step 5, Milling Cutter Fine Adjustment: The first longitudinal moving device 120, the second longitudinal moving device 130, the first lifting part 520, and the second lifting part 540 operate to finely adjust the positions of the two tenon / concave tenon tool mechanisms 530 and the trimming tool mechanism 550. The tenon / concave tenon tool mechanism 530 is positioned in the center of the tenon / concave tenon side of the wall panel 400; the trimming tool mechanism 550 is adjusted to correspond to the positions of the upper and lower side panels of the wall panel 400; the two horizontal cutter heads 551 on both sides can be lowered or raised by the second lifting part 540 according to the wall panel production requirements to determine whether they participate in the trimming work. Step 6, Milling operation start: Start the concave / convex tenon tool mechanism 530 and the trimming tool mechanism 550. The sides of both sides of the wall panel 400 can be processed simultaneously, or one side can be processed at a time. During the processing, the fully automatic spraying device and dust collection device of the waste collection device 600 are turned on to absorb dust pollution. Step 7, Finished Product Transfer: After processing is completed, turn off the milling device 500 and start the conveyor device 200 to transfer the wall panel 400 away from the work area.

[0048] The advantages of this application are as follows: (1) The wall panel is first formed and cured to achieve sufficient strength, ensuring the density and overall stability of the substrate (especially the edge area), so as to provide a solid material strength foundation for subsequent precision processing.

[0049] (2) Replaceable milling cutter: A set of equipment can quickly produce different tenon and mortise models by updating the CNC parameters and replacing the milling cutter, without the need to reprocess the mold to achieve customized and diversified production.

[0050] (3) The concave / convex tenon tool mechanism and the trimming tool mechanism are set up to achieve synchronous milling of concave and convex tenons on both sides through synchronous mirror operation. The concave and convex tenons of the wall panel are efficiently matched, and the precise matching of the concave and convex tenon structure is completed in one pass. This eliminates the positioning error of traditional step-by-step processing, ensures the consistency of the tenon and mortise fit gap, improves the wall panel assembly efficiency and sealing performance, and significantly improves the pass rate of the cut panels. No manual cutting is required, which improves production efficiency, avoids the unsightly appearance caused by manual cutting, and is conducive to standardized production in the factory. Depending on the panel processing technology, single-sided processing can also be selected, which has strong construction flexibility.

[0051] (4) The design of fixing the wall panel and moving the milling device is adopted. The multi-point adsorption and fixing of the wall panel can effectively ensure the stability during the cutting process, reduce the processing waste caused by the displacement of the wall panel due to the movement of the device, and achieve high processing accuracy.

[0052] (5) The special waste tank effectively solves the problem of dust accumulation. The fully automatic spraying device installed on it can effectively reduce dust pollution during the cutting process, avoid tool wear and machining accuracy reduction caused by particle accumulation, and significantly improve the finished product qualification rate.

[0053] (7) The suction cup and vacuum pump can be controlled in sections and can be effectively adjusted according to the length of the wall panel; the trimming tool mechanism can not only trim and mill the side of the wall panel, but also replace the clamping setting required by conventional machinery with the positioning device, and has good stability and adjustability.

[0054] (8) The horizontal moving base and the vertical moving base, the first lifting part and the second lifting part can realize multiple uses of one machine, which is suitable for wall panels of different lengths, thicknesses and sizes, and helps to standardize and industrialize the production of wall panels.

[0055] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
