Description

Technical Field

[0001] This utility model relates to the field of machine tool platform technology, specifically a safety platform for a five-axis high-speed milling center. Background Technology

[0002] Machine tool platforms are specialized auxiliary facilities adapted to CNC machine tools. They are fixed next to the machine tool door for workers to stand and operate. They are mostly made of high-strength steel, with a stable structure and a non-slip surface. Some platforms are equipped with simple guardrails for safety. They are closely aligned with the machine tool's observation window, allowing workers to clearly observe the internal processing status. Some platforms also have small storage platforms for placing operating tools, which not only improves the convenience of observation but also provides stable support for personnel, helping to accurately control the processing process and ensure operational safety. For example, utility model patent CN214520142U discloses a machine tool station, including a frame, columns, a table, and a grid plate. The frame is a rectangular frame structure. The columns have four columns, which are vertically fixed to the bottom surfaces of the four corners of the frame. The frame is horizontally arranged, and the bottom surfaces of the four columns are on the same plane. A frame is fixedly connected to the lower inner wall of the frame. The table is located inside the frame, and the lower surface of the edge of the table presses against the upper surface of the frame. The grid plate is located inside the frame, and the lower surface of the grid plate presses against the upper surface of the table. The grid plate has a mesh arranged in a rectangular array. The grid plate has an anti-slip function, and the table can prevent parts or workpieces from falling below the machine tool station. However, when this utility model is transported and stacked in batches, it is prone to slipping due to bumps and shaking, requiring the use of ropes for reinforcement. This makes the pre-transport work quite complicated, and it cannot be stored when not in use, taking up a lot of space. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a safety platform for a five-axis high-speed milling center. It solves the technical problems of existing devices slipping easily when subjected to bumps and shaking during batch transportation and stacking, requiring the use of ropes for reinforcement, which makes the pre-transportation work more complicated, and the inability to be stored when not in use, which takes up a lot of space.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a safety platform for a five-axis high-speed milling center, comprising a load-bearing frame, two auxiliary support plates slidably connected externally to the load-bearing frame, a stepped seat slidably connected internally to the load-bearing frame, auxiliary grooves provided in the auxiliary support plates, sliders slidably disposed in the auxiliary grooves, limit plates fixedly installed on the lower wall of the sliders, two return springs fixedly installed on the upper wall of the auxiliary grooves, two spring positioning pins fixedly installed on the upper wall of the sliders for limiting the position of the return springs, and limit holes provided on the upper walls of the two auxiliary support plates for insertion into the limit plates.

[0005] Preferably, the load-bearing frame has storage slots on both sides, and limiting slots that communicate with the storage slots are opened at the front and rear of the load-bearing frame. A support rod that is fixed to the auxiliary support plate is slidably connected in the storage slot. A limiting block that is slidably connected to the limiting slot is fixedly installed on the outside of the support rod. A foot pedal is fixedly installed on the upper wall of the load-bearing frame. Extension plates that can be placed on the support rod are hinged on both sides of the foot pedal.

[0006] Preferably, the stepped base has locking grooves on both sides, a locking rod that passes through the load-bearing frame and is inserted into the locking groove is fixedly installed in the auxiliary support plate, the load-bearing frame has slide rails on both sides, and pulleys connected to the slide rails are fixedly installed on both sides of the stepped base.

[0007] Preferably, two fixing slots are provided on both sides of the load-bearing frame, and two fixing plates that are inserted into the fixing slots are fixedly installed in the two auxiliary support plates.

[0008] Preferably, the rear wall of the load-bearing frame is provided with a threaded pin hole that communicates with the fixing groove, and both auxiliary support plates are provided with fixing pin holes. The threaded pin holes and fixing pin holes are connected by threaded pin rods.

[0009] Preferably, the outer walls of the two auxiliary support plates are provided with transport grooves.

[0010] Preferably, the edge of the limiting hole is provided with an assembly chamfer to facilitate insertion.

[0011] Beneficial effects This utility model provides a safety station for a five-axis high-speed milling center, which has the following advantages: As the slider slides in the auxiliary groove, it drives the limiting plate to move synchronously. The return spring maintains stable deformation through the spring positioning pin and applies a continuous downward thrust to the slider, so that the limiting plate naturally inserts into the limiting hole, realizing the rapid locking of the position of the auxiliary support plate. This avoids the auxiliary support plate from accidentally sliding during transportation and solves the problem that existing machine tool platforms are prone to slippage when subjected to bumps and shaking during batch transportation and stacking, requiring the use of ropes for reinforcement, which makes the pre-transportation work more complicated. By using a threaded pin and a fixed plate to restrict the lateral freedom of the two auxiliary support plates, and then by inserting a locking rod into the locking groove, the position of the stepped seat in the load-bearing frame is restricted, thereby increasing the stability of the stepped seat during transportation. This solves the problem that existing machine tool platforms cannot be stored when not in use, which takes up a lot of space. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figures 1-4 A safety platform for a five-axis high-speed milling center includes a support frame 1. Two auxiliary support plates 2 are slidably connected externally to the support frame 1, and a stepped seat 3 is slidably connected internally to the support frame 1. An auxiliary groove 4 is formed within the auxiliary support plate 2, and a slider 5 is slidably disposed within the auxiliary groove 4. A limit plate 6 is fixedly installed on the lower wall of the slider 5, and two return springs 7 are fixedly installed on the upper wall of the auxiliary groove 4. Two spring positioning pins 8 are fixedly installed on the upper wall of the slider 5 to limit the position of the return springs 7. Limiting holes 9 are formed on the upper walls of the two auxiliary support plates 2, which can be inserted into the limit plates 6. In use, the support frame 1 provides core support for the safety platform. The auxiliary support plates 2 can slide along the support frame 1 to adjust the overall width of the platform. When the slider 5 slides within the auxiliary groove 4, it drives the limit plates 6 to move synchronously. The return springs 7 maintain stable deformation through the spring positioning pins 8, applying a continuous downward pushing force to the slider 5, causing the limit plates 6 to naturally insert into the limiting holes 9, achieving rapid locking of the position of the auxiliary support plates 2 and preventing accidental sliding of the auxiliary support plates 2 during transportation.

[0016] Please see Figure 2The support frame 1 has storage slots 10 on both sides and limiting slots 11 connected to the storage slots 10 on the front and back. A support rod 12 fixed to the auxiliary support plate 2 is slidably connected in the storage slots 10. A limiting block 13 slidably connected to the limiting slot 11 is fixedly installed on the outside of the support rod 12. A foot pedal 14 is fixedly installed on the upper wall of the support frame 1. Extension plates 15 that can be placed on the support rod 12 are hinged on both sides of the foot pedal 14. In use, the storage slots 10 provide sliding space for the support rod 12. When the auxiliary support plate 2 is unfolded or retracted, the support rod 12 moves along the storage slots 10. The limiting blocks 13 cooperate with the limiting slots 11 to limit the movement of the support rod 12 and prevent the auxiliary support plate 2 from falling off the support frame 1. The foot pedal 14 provides a basic stepping surface for the staff. The extension plates 15 can be flipped around the hinge point of the foot pedal 14. When retracted, they can be flipped to fit the foot pedal 14 without occupying extra space.

[0017] Please see Figure 4 The step seat 3 has locking grooves 16 on both sides. A locking rod 17 is fixedly installed in the auxiliary support plate 2, passing through the load-bearing frame 1 and inserted into the locking groove 16. The load-bearing frame 1 has slide rails 18 on both sides. The step seat 3 has pulleys 19 connected to the slide rails 18 on both sides. In use, after the locking rod 17 is inserted into the locking groove 16 of the step seat 3, the position of the step seat 3 in the load-bearing frame 1 can be initially fixed. The cooperation between the pulleys 19 and the slide rails 18 converts the sliding friction between the step seat 3 and the load-bearing frame 1 into rolling friction, which greatly reduces the resistance when adjusting the step seat 3, so that the staff can push the step seat 3 to adjust its position without effort. At the same time, it reduces the wear of parts and extends the service life.

[0018] Please see Figure 3 The load-bearing frame 1 has two fixing slots 20 on both sides, and two fixing plates 21 that are inserted into the fixing slots 20 are fixedly installed in the two auxiliary support plates 2. When in use, the insertion and cooperation between the fixing plates 21 and the fixing slots 20 further restricts the relative position between the auxiliary support plates 2 and the load-bearing frame 1, and prevents the auxiliary support plates 2 from shifting in the lateral direction. Especially during transportation, it can enhance the support stability of the auxiliary support plates 2.

[0019] Please see Figure 2-3 The rear wall of the load-bearing frame 1 is provided with a threaded pin hole 22 that communicates with the fixing groove 20. Both auxiliary support plates 2 are provided with fixing pin holes 23. The threaded pin hole 22 and the fixing pin hole 23 are connected by a threaded pin rod 24. When in use, after the threaded pin rod 24 passes through the threaded pin hole 22 and the fixing pin hole 23, it can firmly lock the auxiliary support plate 2 and the load-bearing frame 1, forming a double fixing structure, which completely prevents the auxiliary support plate 2 from loosening or sliding during transportation.

[0020] Please see Figure 1-3The outer walls of the two auxiliary support plates 2 are provided with transport grooves 25. When in use, the transport grooves 25 provide convenient force points for workers to move the safety platform. The platform can be lifted or pushed through the transport grooves 25 without the need for additional tools. Especially when the safety platform needs to be adjusted in position with the five-axis high-speed milling center, it can greatly reduce the difficulty of moving and improve the convenience of operation.

[0021] Please see Figure 3 The edge of the limiting hole 9 is provided with an assembly chamfer 26 to facilitate insertion. In use, the assembly chamfer 26 can guide the limiting plate 6 to be quickly and smoothly inserted into the limiting hole 9, avoiding jamming or edge collision caused by misalignment between the limiting plate 6 and the limiting hole 9, and preventing wear on the edge of the limiting plate 6 or the limiting hole 9 due to hard collision, thus extending the service life of the component.

[0022] In Example 1, when the slider 5 slides in the auxiliary groove 4, it drives the limiting plate 6 to move synchronously. The reset spring 7 maintains stable deformation through the spring positioning pin 8 and applies a continuous downward pushing force to the slider 5, so that the limiting plate 6 naturally inserts into the limiting hole 9, thereby realizing the rapid locking of the position of the auxiliary support plate 2 and preventing the auxiliary support plate 2 from accidentally sliding during transportation.

[0023] Specifically, during transportation, the operator stores the safety platform, then holds the transport trough 25 by hand to lift the safety platform and move it onto the transport vehicle. During the lifting process, the return spring 7 releases its elastic force, pressing the slider 5 down along the auxiliary trough 4 until the slider 5 is pressed against the end of the auxiliary trough 4. At this time, the limiting plate 6 has already extended along the end of the auxiliary trough 4. Then, the extended limiting plate 6 can be aligned with the limiting hole 9 and inserted to achieve the stacking of the two safety platforms. The assembly chamfer 26 can guide the limiting plate 6 to be inserted into the limiting hole 9 quickly and smoothly, avoiding jamming or edge collisions caused by misalignment between the limiting plate 6 and the limiting hole 9, and preventing wear on the edges of the limiting plate 6 or the limiting hole 9 due to hard collisions, thus extending the service life of the components. This can also resist the bumps and swaying generated during transportation, making the transportation more stable.

[0024] In Example 2, the lateral freedom of the two auxiliary support plates 2 is restricted by the cooperation of the threaded pin 24 and the fixing plate 21. Then, the position of the step seat 3 in the load-bearing frame 1 is restricted by the locking rod 17 inserted into the locking groove 16, thereby increasing the stability of the step seat 3 during transportation.

[0025] Specifically, during storage, the operator first unscrews the threaded pin 24 along the threaded pin hole 22, then rotates the two extension plates 15 inward around the foot pedal 14 until the two extension plates 15 are in contact with the foot pedal 14. Next, the operator pushes the step seat 3 into the support frame 1. The step seat 3 moves along the two slides 18 via two pulleys 19. When the step seat 3 is in contact with the rear wall of the support frame 1, the locking groove 16 aligns with the holes on both sides of the support frame 1. At this point, the operator retracts the two auxiliary support plates 2 and the two support rods 12 into the storage slot 10. The two limiting blocks 13 move in conjunction with the limiting groove 11. To enhance the accuracy of storing the two auxiliary support plates 2, so that the two locking rods 17 can be inserted into the locking slots 16 through the holes on both sides of the load-bearing frame 1, the step seat 3 cannot move along the slide 18 under the action of the pulley 19. At the same time that the locking slots 16 are locked, the fixing plate 21 is also inserted into the two fixing slots 20. When the inner side of the two auxiliary support plates 2 contacts the two sides of the load-bearing frame 1, the fixing pin hole 23 is aligned with the threaded pin hole 22. At this time, the threaded pin rod 24 can be screwed into the fixing pin hole 23 along the threaded pin hole 22 to restrict the position of the two auxiliary support plates 2 and enhance the stability during transportation or storage.
