Description

A safety protection device for the edge between the worktable and the pit of a horizontal boring and milling machine Technical Field

[0001] This invention relates to the field of safety protection technology, and in particular to a safety protection device for the edge between the worktable and the pit of a horizontal boring and milling machine. Background Technology

[0002] In the field of mechanical manufacturing, large floor-type boring and milling machines, as key equipment for machining large workpieces, are widely used in various heavy machinery production scenarios due to their wide machining range and strong load-bearing capacity. These machine tools typically have a height difference of approximately 2000mm between the worktable and the fixed pit, and core components such as the machine tool column and operating table need to move in multiple dimensions following the tool's machining trajectory. This unique motion characteristic presents a core challenge for edge safety protection.

[0003] Currently, there is no mature and effective solution in the industry for edge protection between moving parts and fixed pits. Existing protection methods have obvious limitations: some use fixed guardrail structures, but the fixing method seriously conflicts with the movement requirements of the equipment, directly interfering with the X-axis movement of the machine tool column, the Y-axis movement of the spindle head, and the Z-axis movement of the spindle, causing the equipment to be unable to carry out normal processing operations; some attempts use temporary detachable protective structures, which are not only cumbersome to disassemble and assemble, affecting production efficiency, but also have poor protection continuity, making it difficult to cover the entire range of motion of the equipment and failing to form continuous and effective safety protection.

[0004] Essentially, existing protection technologies have failed to overcome the core contradiction between "protection effectiveness" and "equipment operational adaptability." They either restrict equipment movement to ensure protection effectiveness or sacrifice protection performance to meet equipment operational needs, making it impossible to achieve a balance between the two. Summary of the Invention

[0005] The purpose of this invention is to provide a safety protection device for the edge between the worktable and the pit of a horizontal boring and milling machine, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a safety protection device for the edge between the worktable and the pit of a horizontal boring and milling machine, comprising: a machine tool X-axis guide rail; a machine tool device, the machine tool device being mounted on the machine tool X-axis guide rail; a machine tool worktable, the machine tool X-axis guide rail being disposed on the inner side of the machine tool worktable; and a follow-up protection device, the follow-up protection device being installed between the machine tool device and the machine tool worktable, the follow-up protection device being used to follow the machine tool device for follow-up protection.

[0007] Preferably, the machine tool includes: a machine tool base mounted on the X-axis guide rail; a machine tool column fixedly mounted on the upper surface of the machine tool base, with a guide rail mounted on the front of the machine tool column; a spindle box disposed on the front of the machine tool column, the spindle box being slidably connected to the guide rail via a slider; and a spindle mounted on the spindle box.

[0008] Preferably, the follow-up protective device includes: an installation mechanism mounted on a machine tool base; a guide mechanism, with multiple guide mechanisms symmetrically mounted on the installation mechanism; fixed columns symmetrically fixedly mounted on the machine tool worktable; a traction protective mechanism, with both ends of the traction protective mechanism connected to the fixed columns, and the traction protective mechanism interlocking with the installation mechanism; and a load-bearing mechanism mounted on the upper surface of a horizontal support frame.

[0009] Preferably, the mounting mechanism includes: a horizontal support frame, which is horizontally mounted on the machine tool base; a follower column, which is symmetrically mounted at both ends of the horizontal support frame and is perpendicular to the horizontal support frame; and a fixing component, which is connected between the horizontal support frame and the follower column and is used to mount the follower column on the horizontal support frame.

[0010] Preferably, the fixing component includes: a column pressure plate, which is fixedly connected to the bottom end of the follower column; a column base plate, which is fixedly installed on the upper surface of the horizontal support frame, and the column base plate and the column pressure plate are positioned opposite each other; and a first bolt, which is threadedly inserted into the corner between the column pressure plate and the column base plate, and the first bolt is used to install the relative position between the column pressure plate and the column base plate.

[0011] Preferably, multiple sets of the guide mechanisms are installed along the length of the follower column. Each guide mechanism includes: a pulley support frame symmetrically arranged; a pulley shaft inserted between the pulley support frames and located on the inner side of the follower column; a U-shaped groove pulley rotatably disposed outside the pulley shaft; and a second bolt inserted at the corner of the pulley support frame, wherein the pulley support frame is fixedly installed to the follower column by the second bolt.

[0012] Preferably, a rope protection sleeve is inserted and installed on the top of the follow-up column, and the rope protection sleeve is used to guide the follow-up protective equipment.

[0013] Preferably, the bearing mechanism includes: a sleeve support frame, wherein a plurality of sleeve support frames are installed on the upper surface of a horizontal support frame; and a protective sleeve, wherein the protective sleeve is fixedly installed on the sleeve support frame.

[0014] Preferably, the traction protection mechanism includes: a connecting component mounted on a fixed column; a safety rope, the guiding mechanism for guiding the safety rope; and a buckle connected to the end of the safety rope, the buckle being connected between the connecting component and the safety rope.

[0015] Preferably, the connecting assembly includes: a rope mounting ring, which is fixedly mounted on a fixed column; and an adjusting basket, which is hooked onto the rope mounting ring and connected to a locking safety rope.

[0016] The technical effects and advantages of this invention are as follows: This invention utilizes a combination of a guiding mechanism and a traction protection mechanism. The moving column moves left and right along with the machine tool column. During this movement, the distance between the moving column and the fixed column increases or decreases simultaneously in one location while decreasing in the other. However, the safety rope remains fixed at both ends under the guidance of the guiding mechanism. Meanwhile, the spindle box moves up and down under the guidance of the guide rail, and the spindle moves back and forth without interfering with the safety rope's protection. This achieves safety protection between the moving column and the fixed column. The moving protection device can synchronously adjust to the left and right movement of the machine tool column, forming a continuous edge protection barrier. This avoids the protection gaps present in temporary, detachable protection structures, achieving compatibility between the protection function and normal equipment processing. Once installed, it can operate stably for a long time without frequent disassembly, solving the drawbacks of cumbersome disassembly and assembly of temporary protection structures that affect production progress. Furthermore, the adjustable basket allows for quick adjustment of the safety rope to a taut state, facilitating maintenance and reducing interference with the processing flow.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides a safety protection device for the edge between the worktable and the pit of a horizontal boring and milling machine, as shown in Figures 1-4. It includes: a machine tool X-axis guide rail 1; a machine tool device mounted on the X-axis guide rail 1; a machine tool worktable 6, with the X-axis guide rail 1 located inside the worktable 6; and a follow-up protection device installed between the machine tool device and the worktable 6. The follow-up protection device is used to provide follow-up protection along with the machine tool device. The follow-up column 8 moves left and right along with the machine tool column 3. During this movement, the distance between the follow-up column 8 and the fixed column 17 increases or decreases in one direction while simultaneously decreasing in the other. However, the safety rope 20 remains fixed at both ends under the guidance of the guide mechanism. At this time, the spindle box... 4. The vertical movement of the guide rail 31 and the forward and backward movement of the spindle 5 do not interfere with the protection of the safety rope 20, thereby achieving safety protection between the moving column 8 and the fixed column 17. Through the follow-up protective device, the follow-up protective device can be adjusted synchronously with the left and right movement of the machine tool column 3 to form a continuous edge protection barrier, avoiding the protection gap problem of temporary detachable protective structures, and achieving compatibility between the protective function and normal equipment processing. Once installed, it can operate stably for a long time without frequent disassembly and assembly, solving the drawbacks of cumbersome disassembly and assembly of temporary protective structures and affecting production progress. Moreover, the setting of the adjustment basket 19 can quickly adjust the safety rope 20 to a taut state, making maintenance convenient and reducing the interference of protective operations on the processing flow.

[0021] The machine tool equipment includes: a machine tool base 2, which is mounted on the X-axis guide rail 1; a machine tool column 3, which is fixedly mounted on the upper surface of the machine tool base 2, and a guide rail 31 is mounted on the front of the machine tool column 3; a spindle box 4, which is located on the front of the machine tool column 3 and is slidably connected to the guide rail 31 via a slider; and a spindle 5, which is mounted on the spindle box 4 and is guided by the guide rail 31 to facilitate the movement of the spindle box 4, making the linear motion of the spindle box 4 more stable.

[0022] The follow-up protective equipment includes: an installation mechanism, which is installed on the machine tool base 2; a guide mechanism, in which multiple guide mechanisms are symmetrically installed on the installation mechanism; a fixed column 17, which is symmetrically fixedly installed on the machine tool worktable 6; a traction protective mechanism, in which both ends of the traction protective mechanism are connected to the fixed column 17, and the traction protective mechanism and the installation mechanism are interlocked; and a load-bearing mechanism, which is installed on the upper surface of the horizontal support frame 7.

[0023] The installation mechanism includes: a horizontal support frame 7, which is horizontally installed on the machine tool base 2; a follower column 8, which is symmetrically installed at both ends of the horizontal support frame 7 and is perpendicular to the horizontal support frame 7; and a fixing component, which is connected between the horizontal support frame 7 and the follower column 8. The fixing component is used to install the follower column 8 on the horizontal support frame 7. The setting of two follower columns 8 facilitates the installation of the three guide mechanisms.

[0024] The fixing components include: a column pressure plate 81, which is fixedly connected to the bottom end of the follower column 8; a column base plate 82, which is fixedly installed on the upper surface of the horizontal support frame 7, with the column base plate 82 and the column pressure plate 81 positioned opposite each other; and a first bolt 9, which is threadedly installed at the corner between the column pressure plate 81 and the column base plate 82. The first bolt 9 is used to install the relative position between the column pressure plate 81 and the column base plate 82. By loosening the first bolt 9, the relative position between the column pressure plate 81 and the column base plate 82 can be disassembled, thereby facilitating the disassembly of the relative position between the follower column 8 and the horizontal support frame 7.

[0025] Multiple guide mechanisms are installed along the length of the follower column 8. The guide mechanisms include: pulley support frames 10, which are symmetrically arranged; pulley shafts 11, which are inserted between the pulley support frames 10 and located on the inner side of the follower column 8; U-shaped groove pulleys 12, which are rotatably arranged outside the pulley shafts 11; and second bolts 13, which are inserted at the corners of the pulley support frames 10. The pulley support frames 10 are fixedly installed to the follower column 8 by the second bolts 13. The upper two sets of guide devices are used to guide the two sets of traction protection mechanisms respectively, and the lower set is used to change the direction of the safety rope 20 so that the safety rope 20 can be smoothly inserted into the interior of the protective sleeve 16.

[0026] Among them, a rope protection sleeve 14 is inserted and installed on the top of the follow-up column 8. The rope protection sleeve 14 is used to guide the follow-up protective equipment and facilitates the guidance of the safety rope 20.

[0027] The supporting mechanism includes: a sleeve support frame 15, multiple sleeve support frames 15 are installed on the upper surface of the horizontal support frame 7; and a protective sleeve 16, which is fixedly installed on the sleeve support frame 15. The sleeve support frame 15 facilitates the support of the protective sleeve 16, and the protective sleeve 16 facilitates the protection of the safety rope 20.

[0028] Specifically, the traction protection mechanism includes: a connecting component, which is installed on the fixed column 17; a safety rope 20, and a guiding mechanism for guiding the safety rope 20; and a buckle 21, which is connected to the end of the safety rope 20 and is connected between the connecting component and the safety rope 20. The connecting components include: a rope mounting ring 18, which is fixedly installed on the fixed column 17; and an adjusting basket 19, which is hooked onto the rope mounting ring 18 and connected to the safety rope 20 via a locking buckle 21. The adjusting basket 19 is used to adjust the tension of the safety rope 20, keeping it taut through telescopic adjustment to ensure effective protection and adapt to the rope length changes required during equipment movement. The safety rope 20, as the core protective component, forms an edge protection barrier with strong load-bearing capacity and flexible operation, effectively preventing operators from falling into the pit while not interfering with the multi-dimensional movement of the machine tool. The locking buckle 21 is used to fix the two ends and connecting parts of the safety rope 20, achieving a firm connection between the safety rope 20, the rope mounting ring 18, and the adjusting basket 19, preventing the safety rope 20 from falling off and ensuring the reliability of the protective device.
