Description

Technical Field

[0001] This utility model relates to the field of worktable cover technology for flip-type machining centers, specifically a support mechanism for the worktable cover of a flip-type machining center, which is particularly suitable for the sealing and protection of the cover in high-precision, high-frequency worktable exchange scenarios. Background Technology

[0002] With the increasing demand for processing large and complex parts in the aerospace manufacturing industry, the application of flip-type machining centers is becoming more and more widespread. Although its vertically arranged worktable has excellent chip removal performance and machining accuracy, chips and coolant can easily enter the back of the worktable during worktable exchange, causing damage to precision components such as guide rails and racks. Therefore, a cover is needed to achieve sealing protection.

[0003] The existing cover support mechanism of the flip-plate machining center has the following core defects: First, the adjustment dimension is limited, only allowing simple adjustment in the up-down or planar direction, and it cannot take into account the comprehensive and precise adjustment of up-down, left-right and planar parallelism, resulting in insufficient fit between the cover and the worktable and unstable sealing effect; Second, it lacks a buffer and protection structure. When the cover slides along the X-axis with the worktable, it directly and rigidly contacts and rubs against the crossbeam. Long-term use can easily cause wear and deformation of the cover edge, reducing its service life; Third, the fixed mounting method cannot adapt to the installation deviation or angle offset of different base cement columns, resulting in poor versatility. In addition, the support rod connection is too rigid, and the vibration generated by the movement of the worktable is easily transmitted to the cover, further affecting the sealing reliability.

[0004] While existing technologies attempt to optimize adjustment performance through adjusting bolts or slotted holes, they fail to address the core issues of multi-dimensional adjustment, damping and vibration reduction, and universal adaptability, making it difficult to meet the high-precision and long-life requirements of large-scale flip-plate machining centers. Therefore, there is an urgent need for a pull-cover support mechanism with multi-dimensional adjustment capabilities, damping and protection functions, and high versatility to overcome the shortcomings of existing technologies. In view of this, in-depth research was conducted on the above-mentioned problems, leading to this case. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a support mechanism for a workbench cover of a flip-plate machining center, comprising an angle-adjustable fixed seat mounted on a cement column at the rear of the workbench base, a multi-dimensional adjustable support rod with one end fixedly connected to the angle-adjustable fixed seat and the other end connected to an upper support frame, the upper support frame being fixed to the outer frame of the workbench and having upper and lower adjustment bolts at its upper part, the upper support frame having a planar adjustment strip hole extending along the Y-axis at its rear, a fixing bolt passing through the planar adjustment strip hole, a lower support frame being fixedly connected to the outer frame of the workbench, a buffer guide upper crossbeam being bolted to the upper support frame, a buffer guide lower crossbeam being bolted to the lower support frame, and both the buffer guide upper and lower crossbeams having grooves on their inner sides, with buffer slider assemblies embedded in the grooves, the upper and lower ends of the cover being hung on the buffer guide upper and lower crossbeams respectively through the buffer slider assemblies, one side of the cover being fixed to the workbench by bolts, and the other side being sealed to the outer frame of the workbench by an elastic seal.

The ball end of the spherical hinge joint is embedded in the base, and the rod end is fixedly connected to a multi-dimensional adjustment support rod. The locking nut is sleeved on the rod end of the spherical hinge joint to lock and fix the adjusted angle.

[0008] The aforementioned multi-dimensional adjustable support rod includes an outer rod, an inner rod, and a telescopic locking nut. The inner rod is slidably sleeved inside the outer rod. The outer rod has a notch on its side wall. The inner rod is slidably inserted into the outer rod and has a threaded post at its end. The threaded post penetrates the end face of the outer rod. The telescopic locking nut is screwed onto the threaded post and is located on both sides of the connection position between the inner rod and the outer rod. The exposed end of the inner rod is fixedly connected to a spherical hinge joint. The outer rod is detachably connected to the upper support frame.

[0009] The aforementioned upper and lower crossbeams of the buffer guide are both made of 6061 aluminum alloy profiles. The width of the slide groove is 25mm and the depth is 15mm. The body of the buffer slider assembly is made of polyurethane material with a Shore A75 hardness. The surface of the buffer slider assembly is inlaid with a polytetrafluoroethylene wear-resistant layer with a thickness of not less than 2mm.

[0010] The aforementioned pull cover is made of stainless steel corrugated material, and the elastic sealing element is made of silicone strip with a U-shaped cross-section. The elastic sealing element is fixed to the outer frame of the workbench by pressure strips to ensure a tight seal.

[0011] This utility model provides a support mechanism for the pull cover of the worktable in a flip-type machining center. It has the following beneficial effects: 1.

[0018] Example: Refer to the appendix of the instruction manual Figure 1-4 It is known that existing flip-type machining center worktable support mechanisms suffer from insufficient adjustment dimensions, lack of buffer protection, poor versatility, and low reliability. This application provides a large-scale flip-type machining center support mechanism that is compact, offers precise multi-dimensional adjustment, provides significant buffering and vibration reduction, and is highly versatile. The mechanism includes an angle-adjustable fixed seat 1 mounted on a cement column at the rear of the worktable base 10. One end of a multi-dimensional adjustable support rod 2 is fixedly connected to the angle-adjustable fixed seat 1, and the other end is connected to an upper support frame 3. The upper support frame 3 is fixed to the outer frame of the worktable 7 and has upper and lower adjustment bolts 9 at its upper part. An extension along the Y-axis is located at the rear of the upper support frame 3. The planar adjustment slot 14 has a fixing bolt passing through it. The lower support frame 4 is fixedly connected to the outer frame 8 of the workbench. The buffer guide upper crossbeam 5 is bolted to the upper support frame 3, and the buffer guide lower crossbeam 6 is bolted to the lower support frame 4. The inner sides of the buffer guide upper crossbeam 5 and the buffer guide lower crossbeam 6 are provided with sliding grooves. The buffer slider assembly 12 is embedded in the sliding groove. The upper and lower ends of the pull cover 11 are respectively hung on the buffer guide upper crossbeam 5 and the buffer guide lower crossbeam 6 through the buffer slider assembly 12. One side of the pull cover 11 is fixed to the workbench 7 by bolts, and the other side is sealed to the outer frame of the workbench 7 by elastic sealing element 13.

[0019] In the specific implementation process, the aforementioned angle-adjustable fixing seat 1 includes a base 1a, a spherical hinge joint 1b, and a locking nut 1c. The base 1a is fixed to the cement column by expansion bolts. The ball end of the spherical hinge joint 1b is embedded in the base 1a, and the rod end is fixedly connected to the multi-dimensional adjustment support rod 2. The locking nut 1c is sleeved on the rod end of the spherical hinge joint 1b to lock and fix the adjusted angle. The base 1a of the aforementioned angle-adjustable fixing seat 1 is made of Q235 steel plate with a thickness of 20mm. The ball diameter of the spherical hinge joint 1b is 30mm. The locking nut 1c is an M16 high-strength nut to ensure the stability after the angle is fixed.

[0020] In the specific implementation process, the aforementioned multi-dimensional adjustable support rod 2 includes an outer rod 2a, an inner rod 2b, and a telescopic locking nut 2c1c. The inner rod 2b is slidably sleeved inside the outer rod 2a. The outer rod 2a has a notch on its side wall. The inner rod 2b is slidably inserted into the outer rod 2a and has a threaded post at its end. The threaded post penetrates the end face of the outer rod 2a. The telescopic locking nut 2c1c is screwed onto the threaded post and is located on both sides of the connection position between the inner rod 2b and the outer rod 2a. The exposed end of the inner rod 2b is fixedly connected to the spherical hinge joint 1b. The outer rod 2a is detachably connected to the upper support frame 3. The outer rod 2a of the multi-dimensional adjustable support rod 2 is made of φ45mm seamless steel pipe, and the inner rod 2b is made of φ40mm seamless steel pipe with a threaded post at one end. The depth of the inner rod 2b inserted into the outer rod 2a is 50-150mm. The telescopic locking nut 1c is an M16 high-strength nut used in conjunction with an anti-loosening washer.

[0021] In practical implementation, the upper support frame 3 is made of aluminum alloy forging, the upper and lower adjusting bolts 9 are M10 fine thread bolts, and the adjustment accuracy can reach 0.05mm. The length of the planar adjusting strip hole 14 is 80mm and the width is 12mm, which is compatible with M12 fixing bolts. In the specific implementation process, the above-mentioned buffer guide upper crossbeam 5 and buffer guide lower crossbeam 6 are both made of 6061 aluminum alloy profiles, the width of the slide groove is 25mm and the depth is 15mm, the body of the buffer slider assembly 12 is made of polyurethane material with a hardness of Shore A75, and the surface of the buffer slider assembly 12 is inlaid with a polytetrafluoroethylene wear-resistant layer with a thickness of not less than 2mm.

[0022] In the specific implementation process, the above-mentioned pull cover 11 is a stainless steel corrugated cover, the elastic seal 13 is a silicone strip with a U-shaped cross section, and the elastic seal 13 is fixed to the outer frame of the workbench 7 by pressure strip to ensure a tight seal effect.

[0023] When the worktable 7 moves along the X-axis, it drives the pull cover 11 to slide in the grooves of the buffer guide upper crossbeam 5 and the buffer guide lower crossbeam 6 through the buffer slider assembly 12. The buffer slider assembly 12 can effectively reduce friction and impact during the sliding process. By rotating the up and down adjusting bolts 9, the position of the pull cover 11 in the up and down direction can be finely adjusted. Loosening the fixing bolts in the plane adjusting strip hole 14 can adjust the installation angle of the upper support frame 3 to ensure that the pull cover 11 is parallel to the plane of the worktable 7. Adjusting the telescopic locking nut 2c of the multi-dimensional adjusting support rod 2 and pulling the inner rod 2b to slide relative to the outer rod 2a can adjust the position of the pull cover 11 in the left and right directions. Loosening the locking nut 1c of the angle-adjustable fixing seat 1 can adjust the installation angle of the multi-dimensional adjusting support rod 2 to adapt to the installation deviation of the cement column.

[0024] During installation, first fix the base 1a of the angle-adjustable fixing seat 1 to the cement column with expansion bolts. Adjust the angle of the spherical hinge joint 1b according to the installation deviation and tighten the locking nut 1c. Weld the inner rod 2b of the multi-dimensional adjustment support rod 2 to the spherical hinge joint 1b and connect the outer rod 2a to the upper support frame 3 with flange bolts. Adjust the telescopic locking nut 2c to determine the initial left and right positions of the pull cover 11. Fix the upper support frame 3 and the lower support frame 4 to the outer frame 8 of the workbench respectively. Adjust the parallelism between the pull cover 11 and the workbench 7 by adjusting the upper and lower adjustment bolts 9 and the plane adjustment strip hole 14. Finally, hang the pull cover 11 on the crossbeam through the buffer slider assembly 12. Fix one side of the pull cover 11 to the workbench 7 and the other side to the outer frame 8 of the workbench through the elastic seal 13.

[0025] When the worktable 7 is exchanged, the pull cover 11 moves along the X-axis with the worktable 7, and the buffer slider assembly 12 slides in the grooves of the buffer guide upper crossbeam 5 and the buffer guide lower crossbeam 6. The polyurethane body and the polytetrafluoroethylene wear-resistant layer work together to effectively reduce friction and impact. If a sealing deviation is found, it can be precisely corrected at any time through the corresponding adjustment mechanism to ensure long-term reliability.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
