A dustproof structure of a gantry machine tool guide rail

Abstract

This utility model provides a dustproof structure for a gantry milling machine guideway, relating to the field of guideway dustproof technology. It includes a guideway body, which comprises a base. Limit seats are fixedly installed on both sides of the upper surface of the base, and a lead screw is rotatably mounted on one side of each of the two limit seats. In this utility model, by inserting a positioning post on one side of the mounting plate into a hole in the vertical plate, the inclined surface of the first trapezoidal block moves along the through groove under the pushing force of the semi-circular block. The spring is further compressed. When the trapezoidal slot moves to the position of the first trapezoidal block following the positioning post, the spring resets, causing the push plate to move in the opposite direction. This allows the first trapezoidal block to be inserted into the corresponding trapezoidal slot, thus installing the mounting plate on the corresponding side of the vertical plate. The operator pulls the push plate, causing the first trapezoidal block to move and disengage from the corresponding trapezoidal slot, enabling quick disassembly of the bellows cover. The disassembly and assembly steps are simple, and the time required for disassembly and assembly is significantly reduced.

Description

Technical Field

[0001] This utility model relates to the field of dustproof technology for guide rails, and more specifically, to a dustproof structure for guide rails of gantry machine tools. Background Technology

[0002] A gantry milling machine is a large CNC machine tool that uses a "gantry" frame structure to process large, high-precision workpieces. The guide rail is its core moving component, directly affecting the machine tool's positioning accuracy, rigidity, and stability. When using the guide rail, a bellows cover is generally used as a dustproof structure to prevent debris from entering the lead screw structure and to prevent scratching the balls and thread surfaces. For example, the guide rail protective cover for CNC machine tools proposed in publication number "CN217019622U" includes a worktable, a guide rail on the worktable, an accordion-style protective cover on the outer side of the guide rail, a heat dissipation cover in the middle of the accordion-style protective cover, an exhaust fan on the heat dissipation cover, a heat absorption plate on the inner wall of the heat dissipation cover, a heat dissipation fin on the outer wall, a heat conduction column between the heat dissipation fin and the heat absorption plate, mounting brackets at both ends of the accordion-style protective cover, a connecting cover between the mounting bracket and the accordion-style protective cover, an air inlet on the connecting cover, a dustproof net at the air inlet, and the accordion-style protective cover includes a connecting section and a folding section connected in sequence at intervals. The cross-section of the folding section is V-shaped, and multiple heat dissipation blocks are evenly embedded on the side wall of the folding section.

[0003] However, in the above technical solution, since both ends of the bellows cover in the guide rail protective cover are fixed to the guide rail by bolts, each bolt needs to be tightened and loosened one by one during disassembly and assembly. The disassembly and assembly process is cumbersome and time-consuming, which greatly extends the downtime for daily maintenance and emergency repairs. Utility Model Content

[0004] The main purpose of this utility model is to provide a dustproof structure for the guide rail of a gantry milling machine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dustproof structure for a gantry milling machine guide rail includes a guide rail body, the guide rail body including a base, a limit seat fixedly installed on both sides of the upper surface of the base, a lead screw rotatably installed on the opposite side of the two limit seats, an I-beam slide rail fixedly installed on both sides of the upper surface of the base, a slide block slidably arranged on the rail bodies of the two I-beam slide rails, a threaded sleeve fixedly installed on the top of the slide block, and the threaded sleeve is threaded on one side of the lead screw body;

[0007] A bellows cover is provided between each side of the slide and the corresponding limiting seat;

[0010] Each of the positioning columns has a trapezoidal slot.

[0011] Preferably, the second connecting component includes a plurality of sockets, each socket being opened on the side of the upright plate near the corresponding mounting plate. Two mounting holes are opened on both sides of the upright plate. A limit block is fixedly installed in each mounting hole. A sliding column is slidably arranged through one side of each limit block. A stop block is fixedly installed at one end of each sliding column. A spring is sleeved on the side of each sliding column near the stop block. A push plate is fixedly installed at the other end of adjacent sliding columns.

[0012] Two through slots are formed on both sides of the upright plate, and one end of each through slot is connected to the interior of the corresponding insertion hole. Two first trapezoidal blocks are fixedly installed on the opposite side of the two push plates.

[0013] Preferably, a sealing gasket is fixedly installed on the side of each mounting plate near the corresponding upright plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) During installation, by inserting the positioning post on one side of the mounting plate into the insertion hole of the upright plate, the inclined surface of the first trapezoidal block is pushed along the through groove by the semi-circular block, and the spring is further compressed. When the trapezoidal slot moves to the position of the first trapezoidal block along with the positioning post, the spring resets, causing it to drive the push plate to move in the opposite direction, so that the first trapezoidal block can be inserted into the corresponding trapezoidal slot, and the mounting plate is installed on the corresponding upright plate side, thereby quickly installing the bellows cover. During disassembly, the staff pulls the push plate, causing it to move the first trapezoidal block, so that the first trapezoidal block can be disengaged from the corresponding trapezoidal slot, allowing the staff to quickly disassemble the mounting plate from the corresponding upright plate side, thereby quickly disassembling the bellows cover. Compared with the bolt fixing method, the disassembly and assembly steps are simple, the time required for disassembly and assembly is greatly reduced, and the downtime for daily maintenance and emergency repairs is reduced.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] like Figures 1-9 As shown, a dustproof structure for a gantry milling machine guide rail includes a guide rail body 1. The guide rail body 1 includes a base 101. Limit seats 102 are fixedly installed on both sides of the upper surface of the base 101. A lead screw 103 is rotatably installed on the opposite side of the two limit seats 102. I-beam slide rails 104 are fixedly installed on both sides of the upper surface of the base 101. A slide block 105 is slidably provided on the rail body of the two I-beam slide rails 104. A threaded sleeve 106 is fixedly installed on the top of the slide block 105. The threaded sleeve 106 is threaded on one side of the lead screw 103.

[0031] A bellows cover 2 is provided between each side of the slide 105 and the corresponding limiting seat 102;

[0032] Upright plates 3 are fixedly installed on both sides of the slide 105 and on the opposite side of the two limit seats 102. Mounting plates 4 are fixedly installed at both ends of the two bellows covers 2. Each mounting plate 4 is provided with a first connecting component 5 on the side near the corresponding upright plate 3. Each upright plate 3 is provided with a second connecting component 6 on the side near the corresponding mounting plate 4. Adjacent mounting plates 4 and upright plates 3 are connected through the first connecting component 5 and the second connecting component 6.

[0033] The first connecting component 5 includes a plurality of positioning posts 501, each positioning post 501 being fixedly installed on the side of the mounting plate 4 near the corresponding upright plate 3, and a semi-circular block 502 being fixedly installed at one end of each positioning post 501.

[0034] Each positioning post 501 has a trapezoidal slot 503 on its body.

[0035] The second connecting component 6 includes several insertion holes 601. Each insertion hole 601 is opened on the side of the upright plate 3 near the corresponding mounting plate 4. Two mounting holes 602 are opened on both sides of the upright plate 3. A limit block 603 is fixedly installed in each mounting hole 602. A sliding post 604 is slidably arranged through one side of each limit block 603. A stop block 605 is fixedly installed at one end of each sliding post 604. A spring 606 is sleeved on the side of each sliding post 604 near the stop block 605. A push plate 607 is fixedly installed at the other end of adjacent sliding posts 604.

[0036] Two through slots 608 are opened on both sides of the upright plate 3. One end of each through slot 608 is connected to the interior of the corresponding insertion hole 601. Two first trapezoidal blocks 609 are fixedly installed on the opposite side of the two push plates 607.

[0037] Each first trapezoidal block 609 is inserted into the corresponding trapezoidal slot 503, and each positioning post 501 is inserted into the corresponding insertion hole 601. The spring 606 is initially in a compressed state.

[0038] During installation, the positioning post 501 on one side of the mounting plate 4 is inserted into the insertion hole 601 of the upright plate 3. The inclined surface of the first trapezoidal block 609 moves along the through groove 608 under the pushing force of the semicircular block 502, and the spring 606 is further compressed. When the trapezoidal slot 503 moves to the position of the first trapezoidal block 609 along with the positioning post 501, the spring 606 returns to its original position, causing the push plate 607 to move in the opposite direction, so that the first trapezoidal block 609 can be inserted into the corresponding trapezoidal slot 503, thereby installing the mounting plate 4 on the corresponding side of the upright plate 3. The bellows cover 2 can be quickly installed. During disassembly, the operator pulls the push plate 607, which moves the first trapezoidal block 609, allowing the first trapezoidal block 609 to disengage from the corresponding trapezoidal slot 503. This allows the operator to quickly remove the mounting plate 4 from the corresponding upright plate 3, thus quickly disassembling the bellows cover 2. Compared with the bolt fixing method, the disassembly and assembly steps are simple, and it is not necessary to tighten each bolt. The time required for disassembly and assembly is greatly reduced, thus reducing downtime for daily maintenance and emergency repairs.

[0039] In another embodiment of this utility model, a sealing gasket 7 is fixedly installed on the side of each mounting plate 4 near the corresponding upright plate 3.

[0040] One side of the sealing gasket 7 is provided with a through hole corresponding to the positioning post 501.

[0041] When the mounting plate 4 is fixed to one side of the vertical plate 3, the sealing gasket 7 is elastically compressed to ensure a tight fit between the mounting plate 4 and the vertical plate 3, enhance the sealing performance, and effectively prevent external contaminants from entering the guide rail.

[0042] In another embodiment of this utility model, grooves 8 are provided on both sides of the upper surface of each upright plate 3, and a blocking structure 9 for blocking is provided in each groove 8.

[0043] Each push plate 607 has a triangular block 10 fixedly installed on its upper surface.

[0044] The barrier structure 9 includes a positioning frame 901, each positioning frame 901 is fixedly installed inside the corresponding groove 8, and a movable frame 902 is slidably arranged inside each positioning frame 901. A barrier block 903 is fixedly installed at the lower end of the movable frame 902, and a second trapezoidal block 904 is fixedly installed at the top of each movable frame 902.

[0045] When the inclined surface of the first trapezoidal block 609 moves along the through groove 608 under the pushing force of the semicircular block 502, the push plate 607 moves along the direction of the through groove 608. At this time, the triangular block 10 is displaced and does not contact the second trapezoidal block 904, so that when the trapezoidal slot 503 moves to the corresponding position of the first trapezoidal block 609, the push plate 607 can be reset normally. When it is necessary to disassemble the bellows cover 2, the worker pulls the push plate 607, so that the triangular block 10 moves to the position of the second trapezoidal block 904. Under the pushing action of the block 904, the moving frame 902 rises, and the second trapezoidal block 904 can move in the direction of the groove 8. After the triangular block 10 continues to move and the inclined surface disengages from the inclined surface of the second trapezoidal block 904, the moving frame 902 resets and blocks the triangular block 10, so that after the worker releases the push plate 607, it will not reset. After the worker pulls the push plate 607 one by one, the installation plate 4 is moved. Thus, the disassembly of the accordion cover 2 can be completed by only one worker without the need for more manpower.

[0046] The working principle of this dustproof structure for gantry milling machine guideways:

[0047] In use, the positioning post 501 on one side of the mounting plate 4 is inserted into the insertion hole 601 of the upright plate 3. The inclined surface of the first trapezoidal block 609 moves along the through groove 608 under the pushing force of the semi-circular block 502. The spring 606 is further compressed. When the trapezoidal slot 503 moves to the position of the first trapezoidal block 609 along with the positioning post 501, the spring 606 returns to its original position, causing the push plate 607 to move in the opposite direction, so that the first trapezoidal block 609 can be inserted into the corresponding trapezoidal slot 503, and the mounting plate 4 is installed on the corresponding side of the upright plate 3, thereby quickly installing the bellows cover 2. When disassembling, the operator pulls the push plate 607, causing it to move the first trapezoidal block 609, so that the first trapezoidal block 609 can be disengaged from the corresponding trapezoidal slot 503, allowing the operator to quickly disassemble the mounting plate 4 from the corresponding side of the upright plate 3, thereby quickly disassembling the bellows cover 2. The disassembly and assembly steps are simple, and the time required for disassembly and assembly is greatly reduced, reducing the downtime for daily maintenance and emergency repairs.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
