Description

TECHNICAL FIELD

[0001] The application relates to the field of a power-assisted cylinder support machining device, in particular to a power-assisted cylinder support milling machine. BACKGROUND

[0002] The power-assisted cylinder is a hydraulic element applied in an automobile braking system, which can amplify the force of a brake pedal by using hydraulic pressure, thereby increasing the pressure of the braking system and improving the braking effect. Specifically, the power-assisted cylinder can increase the braking force by using hydraulic pressure, improve the efficiency of the automobile braking system, and reduce the braking distance, so that the driver can more easily control the braking of the automobile. Since the power-assisted cylinder can reduce the stepping force of the driver when stepping on the brake plate and relieve the driving fatigue of the driver, the power-assisted cylinder is very important for the safety of the automobile.

[0003] The power-assisted cylinder is usually installed on the body structure in the engine compartment, and the specific position varies with the vehicle type. The power-assisted cylinder support is a mechanical component used for supporting and fixing the power-assisted cylinder, and is used for installing the power-assisted cylinder on the automobile. In the manufacturing and maintenance of the automobile, the power-assisted cylinder support is very important. The power-assisted cylinder support is fixed on the automobile by means of bolt connection, and drilling is a necessary step in the manufacturing process of the power-assisted cylinder support. In order to improve the precision and stability of drilling, the opening part of the power-assisted cylinder support needs to be milled in advance.

[0004] REFERENCE Figure 1 AND Figure 2A power cylinder support 1 includes a base plate 11 and a through hole 12 formed in the base plate 11. The through hole 12 is elliptical and penetrates the base plate 11. A vertically arranged upright plate 13 is fixed to the center of one side of the base plate 11. The top side of the upright plate 13 is inclined towards one side of the base plate 11. The downward inclined end of the top side of the upright plate 13 is flush with the surface of the base plate 11. The part of the upright plate 13 near the through hole 12 is fitted to the edge of the through hole 12. A vertically arranged side plate 14 is fixed to the upward inclined end of the upright plate 13. The bottom end of the side plate 14 is fixed to one side of the base plate 11. One edge of the side plate 14 is fixed to one end of the upright plate 13. The side plate 14, the upright plate 13, and the base plate 11 are perpendicular to each other. A vertically arranged inclined plate 15 is fixed to the part of the upright plate 13 and the side plate 14. The bottom end of the inclined plate 15 is fixed to one edge of the base plate 11 and is flush with the bottom edge. The inclined plate 15 is fixedly connected to the side of the upright plate 13 away from the side plate 14 on one side. The side of the inclined plate 15 away from the side plate 14 is inclined in the direction away from the through hole 12. A vertically arranged side plate 2 16 is fixedly connected to the side of the inclined plate 15 away from the side plate 14. The side plate 2 16 is parallel to the side plate 14. The bottom end of the side plate 2 16 is fixedly connected to one side of the bottom plate 11 and fits against the edge of one side of the bottom plate 11. A milled side part 17 is fixedly connected to the side of the side plate 14 and the side plate 2 16 away from the bottom plate 11. The milled side part 17 is plate-shaped. The two milled side parts 17 are respectively located at the opposite edge of the side plate 14 and the side plate 2 16. The two milled side parts 17 are respectively fitted against the edges of the side plate 14 and the side plate 2 16. Four milled bottoms 18 are fixedly connected to the four corners of the bottom side of the bottom plate 11. The milled bottoms 18 are plate-shaped.

[0005] The milling process involves milling the milling plane of the power cylinder bracket 1 to form the milled bottom 18 and the milled side 17, in order to facilitate subsequent drilling. Typically, the cutting tools of milling lathes are positioned close to the fixed workpiece assembly and corresponding to the milling plane of the workpiece. Currently, milling lathes with low automation rely on manual loading by workers. First, the cutting tool is moved away from the fixed assembly, then the worker mounts the workpiece onto the fixed assembly. After fixing, the cutting tool feeds to complete the milling. Once the cutting tool has reset, the worker manually removes the workpiece from the fixed assembly, completing the milling process for one workpiece.

[0006] Regarding the aforementioned technologies, the inventors believe that the manual loading and unloading methods by workers are inefficient, and that the workers' hands are placed under the cutting tool, posing a significant risk of injury. Summary of the Invention

[0007] To improve the safety of milling lathe operation and optimize the loading and unloading process of milling lathe, this invention provides a power cylinder bracket milling machine.

[0008] The present invention provides a power cylinder bracket milling machine with the following technical solution:

[0009] A milling machine for a power cylinder support includes a milling table mounted on the milling machine. A fixed block is mounted on the milling table. A horizontally arranged milling cutter disc is rotatably connected to one side of the milling machine corresponding to the fixed block. Two vertically arranged milling cutter discs are rotatably connected above the fixed block, with the two milling cutter discs corresponding to opposite edges on the top side of the fixed block. The fixed block consists of a fixed block one and a fixed block two. The top side height of the fixed block one is lower than the top side height of the fixed block two. A mounting groove for engaging a vertical plate is formed between the fixed block one and the fixed block two. An inclined portion for adapting an inclined plate is provided on the side of the fixed block two that is higher than the fixed block one. A fixing component is mounted on the fixed block. The milling table has four sides... All edges are equipped with splash guards. One splash guard near the milling cutter head consists of an upper fixed splash guard and a lower rotating splash guard. The end of the milling cutter head near the fixed block passes through the fixed splash guard. The bottom of the fixed splash guard is lower than the height of the milling cutter head. The bottom of the fixed splash guard abuts against the top of the rotating splash guard. Multiple parallel slide bars are fixed to the bottom of the milling table. The milling machine has a slide rail for each slide bar. A guide rod is inserted into each slide bar. The axis of the guide rod is parallel to the length direction of the slide bar. Each guide rod extends from the end of the slide bar to one side of the milling machine. One side of the slide bar is equipped with an active component for driving the slide bar to slide. A recovery groove is provided on the side of the milling machine below the guide rod.

[0010] By adopting the above technical solution, the first fixing block is lower in height and corresponds to the first side plate, while the second fixing block is higher in height and corresponds to the second side plate. The height difference between the top sides of the first and second fixing blocks corresponds to the distance between the first and second side plates. When the power cylinder bracket is positioned on the first and second fixing blocks, the upright plate of the power cylinder bracket is snapped into the mounting groove. Since the upright plate is vertically snapped in, for smooth installation, the width of a portion of the mounting groove should be adapted to the part of the upright plate near the through hole. Thus, the simple positioning of the power cylinder bracket is achieved through the simple structural cooperation of the first fixing block, the second fixing block, and the mounting groove. Furthermore, the fixing components provide stable fixation of the power cylinder bracket during milling, simplifying the fixing process. The key to this solution is optimizing the loading and unloading process by moving a portion of the fixing block off the milling table using a slide bar and guide rod. In this design, when the operator is milling the power cylinder bracket, they stand on the side of the milling machine where the guide rod extends. The active component pushes the fixing block along the guide rod to slide off the milling table, away from the milling cutter head, and closer to the operator. The operator then fixes the power cylinder bracket onto the fixing block. At this point, the operator can quickly disassemble and replace the power cylinder bracket without being limited by the cutting edge on the milling cutter head, which would otherwise result in a slow replacement speed. Furthermore, because the operator installs the bracket after moving away from the milling table, the feed and retraction of the milling cutter head do not need to consider the operator's safety, reducing the amount of feed and retraction of the milling cutter head and keeping it close to the fixing block, thus reducing the motion load on the milling machine motor. Since most of the milling chips are concentrated on the side of the milling table closest to the fixing block, moving the milling table closer to the operator makes it easier for them to clean them up.

[0011] Optionally, the fixing component includes a vertically mounted vertical corner cylinder on the side of the fixing block one away from the milling cutter disc one. The cylinder body of the vertical corner cylinder is fixed to the fixing block one, and the rotating rod of the vertical corner cylinder is located above the fixing block one. The vertical corner cylinder is used to fix the side plate one. An arc-shaped groove is opened on the side of the fixing block two near the milling cutter disc one. A transversely mounted horizontal corner cylinder is arranged in the arc-shaped groove. The rotating rod of the horizontal corner cylinder extends out of the surface of the arc-shaped groove near the milling cutter disc one. The horizontal corner cylinder is arranged corresponding to the through hole.

[0012] By adopting the above technical solution, the rotating rod of the angle cylinder can change its distance from the cylinder body while rotating. Utilizing the operating characteristics of the angle cylinder, a simple fixing method is designed: when the rotating rod of the angle cylinder rotates above the fixed block, the angle cylinder retracts its rod, causing it to abut against the fixed block bracket. When the worker places the power cylinder bracket on the top side of the fixed block, the vertical and horizontal angle cylinders operate simultaneously. For a more intuitive understanding, the operating processes of the vertical and horizontal angle cylinders in this solution are explained separately. The rotating rod of the vertical angle cylinder remains perpendicular to the output rod. The vertical angle cylinder pushes the rotating rod upwards. When the height of the rotating rod is higher than the height of the power cylinder bracket base plate... When the lever rotates 90 degrees upwards towards the booster cylinder bracket, the vertical angle cylinder pulls the lever downwards until it abuts the base plate surface. The middle part of the lever of the horizontal angle cylinder is fixed to the output rod, forming a T-shape. Utilizing the shape characteristics of the elliptical through hole, the length of the lever of the horizontal angle cylinder is greater than the short axis of the through hole but shorter than the long axis. The lever at the initial position is parallel to the long axis of the through hole. The horizontal angle cylinder extends the lever. When the lever passes through the through hole and extends to the outside of the booster cylinder bracket surface, the lever rotates 90 degrees, becoming parallel to the short axis of the through hole. Then the lever is retracted, so that both ends of the lever abut against the booster cylinder bracket. This is achieved by using two mutually perpendicular angle cylinders, taking advantage of the physical structural characteristics of the booster cylinder bracket.

[0013] Optionally, each of the guide rods is provided with threads, and the guide rods are threadedly connected to the slide bars. The milling machine is provided with a rotation drive component for each guide rod.

[0014] By adopting the above technical solution, a lead screw drive is used instead of the ordinary sliding method of the milling table. This solution uses a lead screw drive mainly due to the four advantages of lead screws: First, lead screw drives have the advantage of high precision, enabling minute displacement control and precise position adjustment. Under the same precision, controlling the linear displacement of the lead screw to control the sliding distance of the milling table is more accurate than directly controlling the sliding distance of the milling table. Second, lead screw drives have the advantage of strong load resistance. Multiple lead screws evenly distribute the weight of the assist cylinder bracket, maintaining the axial accuracy of the lead screws for a long time and improving the service life of the lead screws. Third, lead screws have the advantage of high efficiency and energy saving. The friction of the lead screw is small during operation, and the slider and lead screw maintain a high degree of synchronization, enabling long-term stable operation and a long service life. Fourth, lead screw drives have good self-locking performance, which can prevent reverse rotation of the load and maintain the safety of the system.

[0015] Optionally, the rotation drive includes a servo motor arranged laterally corresponding to the guide rod, the servo motor being fixedly connected to one side of the milling machine, and the output shaft of the servo motor being fixedly connected to the end of the guide rod.

[0016] By adopting the above technical solution, the high precision of the lead screw drive allows for precise control of the lead screw's linear displacement, enabling the milling table to be accurately transported to a position convenient for workers to load and unload materials. Servo motors, widely used in industrial production and machinery manufacturing, meet the demands of high precision, high speed, and high load, making them the preferred choice for this solution. Servo motors also offer fast response times, quickly responding to control signals to achieve high-speed movement and rapid stopping. Furthermore, their strong programmability allows for the implementation of various control algorithms and modes to meet diverse application requirements. In addition, servo motors offer high control precision, enabling high-precision speed and force control.

[0017] Optionally, the fixed block is slidably connected to the milling table, and a slider is fixedly connected to the bottom end of the fixed block. The length direction of the slider is towards the milling cutter head. The milling table has a groove corresponding to the slider, and a driving component for driving the fixed block is provided on the milling table.

[0018] By adopting the above technical solution, the sliding connection between the fixed block and the milling table is applied to the loading and unloading of the power cylinder bracket. The worker stands on one side of the milling machine, and the milling table transports the power cylinder bracket, which has been milled, out of the milling machine and closer to the worker. Since the surfaces of the power cylinders are in close contact with the surfaces of fixed block one and fixed block two, the worker would need to use his hands to pry off the power cylinder bracket directly. Therefore, a driving component is needed to drive the fixed block to slide a certain distance, creating a gap between the power cylinder bracket and fixed block two, making it easier for the worker to disassemble. In addition, the reason for choosing fixed block one as the sliding fixed block is to take into account the worker's position. After the milling table transports the power cylinder bracket out of the milling machine, fixed block one is the fixed block away from the end of the milling machine. After fixed block one slides a certain distance toward the worker, the gap between the power cylinder bracket and the fixed block is closer to the end of the milling machine. While the worker's hand on the side closer to the milling machine is unloading, the worker's hand on the side away from the milling machine can simultaneously load the power cylinder bracket, which is conducive to smooth operation and improves efficiency.

[0019] Optionally, the driving component includes an electric push rod that is laterally disposed on one side of the milling table. The electric push rod is fixedly connected to the milling table, and the output rod of the electric push rod is fixedly connected to the bottom of one side of the fixed block.

[0020] By adopting the above technical solution, the electric linear actuator is used as the driving component of the fixed block. Compared with the servo motor, the electric linear actuator also has the advantages of high precision, high reliability, and easy control. However, the electric linear actuator has a smaller force limit and no load-bearing capacity. Since the fixed block only serves as a fixing component for the auxiliary cylinder bracket, the driving component of the fixed block does not need to consider the force and load-bearing conditions. It does not need to use the more expensive servo cylinder, and the fixed block does not need to consider the precision issue. The displacement is just about enough. Among all the instruments that meet the above conditions, the electric linear actuator has the lowest cost.

[0021] Optionally, the portion of the milling table without a fixing block is inclined downwards in a direction away from the fixing block.

[0022] By adopting the above technical solution, due to the blocking effect of the splash guard, iron filings accumulate on the milling table. In order to prevent iron filings from accumulating near the fixed block and affecting the fixation of the booster cylinder bracket, the part of the milling table corresponding to the fixed block is tilted downwards in the direction away from the fixed block, so that the scrap iron filings generated by milling can slide down along the tilted part and facilitate subsequent cleaning by the staff.

[0023] Optionally, of the four splash guards, the bottoms of two splash guards with their surfaces perpendicular to the axial direction of the guide rod are fixed to the milling table. These two splash guards fixed to the milling table are the first splash guards. A rotating splash guard is set perpendicular to the two first splash guards. A horizontally oriented connecting rod is fixed to the middle part of each side of the rotating splash guard. The two connecting rods are rotatably connected to the two first splash guards. The splash guard on the opposite side of the rotating splash guard is the second splash guard. A connecting rod is fixed to the middle part of each side of the second splash guard. The two connecting rods are rotatably connected to the two first splash guards.

[0024] By adopting the above technical solution, the splash guards are used to block iron filings from flying. The connection method of two splash guards parallel to the sliding direction of the milling table facilitates the worker to clean the iron filings accumulated on the milling table. For ease of description, the direction in which the milling table slides out of the milling machine during unloading is called the front side, the corresponding side is the rear side, and the other two sides are called the left and right sides. The front and rear splash guards of the four sides of the milling table are fixed to the milling table. The height of the front and rear splash guards is higher than the top side of the fixed block two but lower than the height of the milling cutter head two after reset. The front and rear splash guards only serve to prevent iron filings from flying. The left and right splash guards can rotate parallel to the front and rear sides. The splash guards on both sides rotate in the direction of their surfaces. When there is enough scrap metal accumulated on the milling table, the operator can rotate the splash guards on both sides away from the milling table when unloading the material. A gap is created between the bottom of the splash guard and the edge of the milling table, and the scrap metal slides down into the recycling tank along the gap. It should be noted that the splash guard on the side closer to the milling cutter head on both sides should avoid interfering with the milling cutter head shaft when the milling table slides. To avoid physical obstruction, the splash guard on the milling cutter head is divided into two parts. The top part is fixed to the motor housing that drives the milling cutter head, and only the bottom part is rotatably connected to the front and rear splash guards as described above.

[0025] Optionally, a power distribution box is provided on one side of the recycling tank near the recycling tank, and a control panel is provided on the top side of the power distribution box.

[0026] By adopting the above technical solution, the control panel and power distribution box are set on one side of the guide rod extending out of the milling machine, close to the operator's position. The operator can control the operation of the servo motor, the operation of the electric push rod, the feed of the milling cutter head, etc. through the control panel. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 3-7 This application will be described in further detail.

[0036] This application discloses a milling machine for a power steering cylinder bracket. (Refer to...) Figure 3A milling machine for a power cylinder support includes a milling table 3 mounted on a milling machine 2 and milling cutter discs 21 mounted on the milling table 3. The milling cutter discs 21 include a horizontally mounted first milling cutter disc 211 and two vertically mounted second milling cutter discs 212. The cutting head end of the first milling cutter disc 211 extends to the top of the milling table 3 from one side. Both second milling cutter discs 212 are mounted on the top of the milling table 3. The milling machine 2 is equipped with drive motors corresponding to the three milling cutter discs 21. A power distribution box 22 is fixedly connected to one side of the machine body, and a control panel 23 is fixedly connected to the top of the power distribution box 22. Before operating the milling machine 2 each day, the staff checks the operating parameters of the milling machine 2 through the control panel 23, and controls the feed and retraction distance of the milling cutter head 21. An incorrect feed distance will affect the thickness of the power cylinder bracket 1, which is very dangerous for automotive parts with high requirements. An incorrect retraction distance will continuously increase the operating burden of the milling machine 2. After the check is correct, the worker continues to feed the material onto the milling table 3. After the milling cutter head 21 completes the milling of the power cylinder bracket 1, the material can be unloaded.

[0037] Reference Figure 4 and Figure 5The mounting platform is equipped with a first mounting block 31 and a second mounting block 32. The top side of the second mounting block 32 is higher than that of the first mounting block 31. The first mounting block 31 is positioned corresponding to the side plate 14 of the power cylinder bracket 1, and the height of the second mounting block 32 is positioned corresponding to the side plate 16 of the power cylinder bracket 1. The difference in the top side height between the first mounting block 31 and the second mounting block 32 corresponds to the difference in the distance between the side plates 14 and 16. The portion of the second mounting block 32 that is higher than the first mounting block 31 is inclined on the side closest to the first mounting block 31. The inclined part is inclined downward towards the side of the fixing block 31; a mounting groove 33 is formed between the fixing block 31 and the fixing block 32, and the mounting groove 33 is set corresponding to the upright plate 13 of the booster cylinder bracket 1. The fixing block 32 is provided with an arc-shaped groove 34 corresponding to the through hole 12 of the booster cylinder bracket 1. The arc-shaped groove 34 is connected to the mounting groove 33. The shape of the groove wall on the side of the arc-shaped groove 34 away from the mounting groove 33 corresponds to the part of the upright plate 13 near the through hole 12; the side of the fixing block 32 away from the milling cutter disc 211 is provided with A vertically arranged vertical corner cylinder 35 is provided, with its cylinder body fixed to the top portion of the fixing block 31 on that side. The rotating rod of the vertical corner cylinder 35 is set upwards. A horizontally arranged transverse corner cylinder 36 is provided at the intersection of the mounting groove 33 and the arc-shaped groove 34 on the fixing block 31. The cylinder body of the transverse corner cylinder 36 is fixed to the fixing block 31, and the rotating rod of the transverse corner cylinder 36 approaches the side of the milling cutter disc 211. A sliding groove 3 is provided on the milling table 3 corresponding to the fixing block 31. 8. A slider is fixedly connected to the bottom of the fixed block 31 corresponding to the slide groove 38. The fixed block 31 is slidably connected to the milling table 3. An electric push rod 37 is provided on the side of the milling table 3 away from the milling cutter disc 211 corresponding to the fixed block 31. The cylinder of the electric push rod 37 is fixedly connected to the milling table 3. The output rod of the electric push rod 37 is parallel to the length direction of the slide groove 38. The piston rod of the electric push rod 37 is fixedly connected to the bottom of the fixed block 31. The parts of the four sides of the milling table 3 without fixed blocks are inclined away from the fixed blocks. Fixed block 1 31, fixed block 2 32, mounting groove 33 and arc groove 34 cooperate to position the booster cylinder bracket 1. Horizontal corner cylinder 36 and vertical corner cylinder 35 fix different parts of the booster cylinder bracket 1 respectively. The two work together to fix the booster cylinder bracket 1 positioned on the fixed block, so that milling cutter disc 1 211 and milling cutter disc 212 can stably mill the booster cylinder bracket 1. The milled chips slide down the inclined part of the milling table 3. Finally, the worker unloads the milled booster cylinder bracket 1.

[0038] Reference Figure 1 and Figure 6The milling machine 2 has two horizontally opened slides 24 on the bottom side of the milling table 3. The length direction of the slides 24 is perpendicular to the axial direction of the milling cutter head 211. A slide frame 25 is fixedly connected to each slide 24 on one side of the milling machine 2. The slides 24 extend to the slide frame 25 and are smoothly connected to the slide frame 25 and the milling machine 2 respectively. A recovery groove 26 is provided below the slide frame 25. A lead screw 27 is rotatably connected in each slide 24. Both ends of each lead screw 27 are rotatably connected to the inner walls of both ends of the slide 24. A slide bar 28 is fixedly connected to each slide 24 on the bottom side of the milling table 3. The slide bar 28 is threadedly connected to the two lead screws 27. A servo motor 29 is fixedly connected to each lead screw 27 in each slide 24 on one side of the milling machine 2. The output shaft of the servo motor 29 passes through the end side wall of the slide 24 and is fixedly connected to the end of the lead screw 27. To improve the dangerous situation of workers putting their hands between the milling cutter heads 21 to load and unload materials, the milling table 3 is slidable by means of lead screw 27 transmission. Two servo motors 29 rotate synchronously to move the milling table 3 to a part away from the milling cutter heads 21. Then the worker disassembles the milled booster cylinder bracket 1 and installs a new booster cylinder bracket 1 on the fixed block.

[0039] Reference Figure 6 and Figure 7Each of the four edges of the milling table 3 is provided with a splash guard 4. For ease of description, the direction in which the milling table 3 slides toward the carriage 25 is taken as the front, and based on the front, there are rear and left and right sides. The bottom of the two splash guards 4 on the front and rear sides are fixed to the edges of the front and rear sides of the milling table 3, respectively, and the two splash guards 4 on the front and rear sides are set vertically. The middle part of the splash guards 4 on the left and right sides away from the milling cutter head 211 is fixed with an axially horizontally set connecting rod 43. The ends of the two connecting rods 43 away from the splash guard 4 are rotatably connected to the two splash guards 4 on the front and rear sides on the same side, respectively. The two connecting rods 43 are each fitted with a torsion spring 44 to connect the two adjacent splash guards 4. A splash guard 4 near the milling cutter head 211 is horizontally divided into two parts: a fixed splash guard 41 at the top and a rotating splash guard 42 at the bottom. The fixed splash guard 41 is fixed to the motor housing of the driving milling cutter head 211 on the side away from the milling table 3. The bottom of the fixed splash guard 41 is lower than the height of the milling cutter head 211. The milling cutter head 211 extends through the fixed splash guard 41 to the top of the milling table 3. A connecting rod 43 is fixed to the middle part of the two edges of the rotating splash guard 42. The end of the connecting rod 43 away from the splash guard 4 is rotatably connected to the two splash guards 4 on the front and rear sides respectively. A torsion spring 44 connecting the two adjacent splash guards 4 is sleeved on the outside of the two connecting rods 43. The main function of the splash guard 4 is to prevent iron filings from flying during milling. Flying iron filings not only pollute the surrounding environment, but may also scratch the skin of workers and cause work-related injuries. During milling, the splash guard 4 blocks the iron filings inside the milling table 3 and slides down the inclined part of the bottom side of the milling table 3, accumulating on the splash guard 4. When the milling table 3 slides above the recovery tank 26, the worker rotates the left and right splash guards 4 around the connecting rod 43 in a direction away from the milling table 3. There is a gap between the bottom of the left and right splash guards 4 and the bottom side of the milling table 3. The iron filings slide along the gap into the recovery tank 26. Due to the setting of the torsion spring 44, the splash guard 4 will automatically reset after the worker releases it. In addition, since the fixed splash guard 41 cannot slide with the milling table 3, the empty part above the rotating splash guard 42 can facilitate the worker standing on one side of the rotating splash guard 42 to load materials.

[0040] The implementation principle of the milling machine with a power cylinder bracket in this application embodiment is as follows: In order to improve the problem that workers need to put their hands between multiple milling cutter discs 21 when loading materials, which is somewhat dangerous, the milling table 3 is pushed away from the milling cutter discs 21 by a sliding component when the worker loads materials. Then the worker loads materials on one side of the milling machine 2. After loading, the sliding component pulls the milling table 3 to slide closer to the milling cutter discs 21, which not only improves the loading efficiency of the milling machine 2, but also ensures the safety of the loading process of the milling machine 2.

[0041] Workers pre-set control parameters according to different workpiece specifications and models. In this embodiment, in order to improve the loading and unloading efficiency of milling machine 2 and improve the automation process of milling machine 2, workers reserve machine downtime according to their actual working conditions for manual disassembly and assembly of the booster cylinder bracket 1. The specific process of loading and unloading milling machine 2 is as follows.

[0042] Two servo motors 29 rotate synchronously according to the pre-set program, driving the lead screw 27 to rotate. The rotation of the lead screw 27 causes the milling table 3 to slide towards the slide 25. The worker stands on one side of the milling machine 2. During the sliding process, the horizontal corner cylinder 36 and the vertical corner cylinder 35 are reset respectively, and the fixation of the auxiliary cylinder bracket 1 is canceled. The electric push rod 37 extends the piston rod and pushes the fixed block 31 a certain distance along the slide 38 towards the worker. A gap appears between the auxiliary cylinder bracket 1 and the fixed block 31. When the milling table 3 slides to the worker's position, the servo motor 29 pauses for a pre-set time to allow the worker to unload and load materials.

[0043] According to the preset time difference, the electric push rod 37 maintains the extended piston rod state. After the worker's hand reaches into the gap to remove the booster cylinder bracket 1, the piston rod of the electric push rod 37 is reset. Then, the worker aligns the side plate 14 of the booster cylinder bracket 1 with the top side of the fixing block 31, the side plate 16 with the top side of the fixing block 32, the vertical plate 13 with the mounting groove 33, and the curved part of the vertical plate 13 near the through hole 12 with the arc groove 34, thus snapping the booster cylinder bracket 1 onto the fixing block. After the servo motor 29 pauses for a few seconds, it drives the lead screw 27 to rotate in the opposite direction, resetting the milling table 3. During the sliding process of the milling table 3 toward the milling cutter head 21, the vertical corner cylinder... The vertical angle cylinder 35 works together with the horizontal angle cylinder 36. The vertical angle cylinder 35 pushes the rotating rod upward. When the height of the rotating rod is higher than the height of the base plate 11 of the booster cylinder bracket 1, the rotating rod rotates 90 degrees upward towards the booster cylinder bracket 1. Then the vertical angle cylinder 35 pulls the rotating rod downward until the rotating rod abuts the surface of the base plate 11. The horizontal angle cylinder 36 extends the rotating rod. When the rotating rod passes through the through hole 12 and extends to the outside of the surface of the booster cylinder bracket 1, the rotating rod rotates 90 degrees and is parallel to the short axis of the through hole 12. Then the rotating rod is retracted so that both ends of the rotating rod abut the booster cylinder bracket 1 to complete the fixation. After the milling table 3 is reset, the servo motor 29 stops operating, completing the loading and unloading.

[0044] As the chips are blocked by the splash guard 4 during milling, they continue to accumulate on the milling table 3. When the accumulation obstructs the installation of the auxiliary cylinder bracket 1, the worker should rotate the rotating splash guard 42 and the splash guard 4 on the opposite side of the rotating splash guard 42 around the connecting rod 43 before loading the material, so that the chips slide down the inclined part of the milling table 3 into the recycling tank 26. The worker then releases the splash guard 4, and the torsion spring 44 resets the two splash guards 4.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
