Description

Technical Field

[0001] This utility model relates to the field of seat polishing technology, specifically a polishing device for the production of lightweight high-speed rail seats. Background Technology

[0002] As a key component of high-speed rail carriages, the use of lightweight materials in the manufacture of high-speed rail seats is a crucial step in achieving overall train weight reduction. Currently, lightweight high-speed rail seats mostly utilize composite materials and new aluminum alloys, ensuring a long service life and high safety performance. Their lighter weight also effectively reduces the overall weight of the train. However, the polishing process in the production of lightweight high-speed rail seats presents numerous challenges. After the seat frame undergoes the molding process, surface imperfections such as burrs and unevenness often remain. If not properly addressed, these imperfections not only affect the seat's appearance but may also pose safety hazards such as scratches to passengers during use.

[0003] Traditional manual polishing methods rely on workers to repeatedly polish the seat frame with sandpaper. This process requires workers to manually press and fix the seat frame, and also to frequently adjust the frame angle to ensure that all parts are polished. This is extremely inconvenient and consumes a lot of manpower and time, resulting in low polishing efficiency. To address these issues, we propose a polishing device for the production of lightweight high-speed rail seats. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for the production of lightweight high-speed rail seats, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for producing lightweight high-speed rail seats, comprising a base and a support plate installed at the top center of the base. The upper end of the support plate has a through groove. A grinding cylinder is rotatably connected to the front side of the top of the base. A connecting shaft is fixed at the center of the grinding cylinder. The top of the support plate is rotatably connected to the top of the connecting shaft via a swivel. A pulley is fixed at the upper end of the connecting shaft. A drive motor is installed on the outer wall of the rear end of the support plate. A pulley is installed at the output end of the drive motor. A drive belt is provided between the drive motor and the pulley. Multiple sets of grinding soft rods are installed at equal intervals inside the grinding cylinder. Clamping components are provided on both sides of the lower end of the through groove.

[0006] As a further preferred embodiment of this technical solution, the clamping assembly includes a clamping seat, a slot, a sleeve, a sliding column, a connecting plate, a locking block, a connecting rod, a return spring, and a handle. Clamping seats are fixed on both sides below the through slot. Slots are provided at the front ends of both sets of clamping seats. Sleeves are fixed to opposite ends of both sets of clamping seats. Sliding columns are provided inside both sets of sleeves. Locking blocks are connected to the front ends of both sets of sliding columns via connecting rods and connecting plates. Return springs are wound around the outside of both sets of connecting rods. A handle is fixed to the front end of both sets of connecting plates.

[0007] As a further preferred embodiment of this technical solution, a control box is installed on the side of the support plate, and the input end of the drive motor is electrically connected to the control box through a wire.

[0008] As a further preferred embodiment of this technical solution, the outer wall of the sliding column is fully fitted with the inner wall of the sleeve, and the sliding column and the sleeve are slidably connected.

[0009] As a further preferred embodiment of this technical solution, the inner wall of the slot is provided with anti-slip texture, and the surface of the card block is covered with a rubber layer.

[0010] As a further preferred embodiment of this technical solution, the two ends of the return spring are respectively connected to the outer wall of the slide column and the inner wall of the sleeve, and the slide column is elastically connected to the inner wall of the sleeve through the return spring.

[0011] This utility model provides a grinding device for the production of lightweight high-speed rail seats, which has the following advantages:

[0012] 1. This utility model involves mounting a rotatable grinding cylinder on a base, and installing multiple sets of detachable grinding rods inside the grinding cylinder. The seat frame to be ground can be placed inside the grinding cylinder, and the drive motor drives the pulley on the connecting shaft to rotate, causing the grinding cylinder to rotate at a constant speed under the drive of the connecting shaft. This allows the multiple sets of grinding rods inside the grinding cylinder to quickly grind the seat frame inside the grinding cylinder. The flexible material of the grinding rods can adapt to the slight concavities and convexities of the curved surface of the seat frame, achieving uniform grinding and effectively improving grinding efficiency.

[0013] 2. This utility model has two sets of clamps installed on the upper end of the grinding cylinder, which can place the seat frame inside the slot. Then, the return spring outside the connecting rod releases its elasticity to push the sliding column backward, allowing the connecting plate to drive the clamping block to quickly insert into the slot. The clamping block and the slot effectively fix the seat frame, achieving quick locking and facilitating the grinding of local parts of the seat frame. Attached Figure Description

If the specific posture changes, the directional indicator will also change accordingly.

[0021] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0022] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0023] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a grinding device for producing lightweight high-speed rail seats includes a base 1 and a stand plate 2 installed at the top center of the base 1. A through groove 3 is provided on the upper end of the stand plate 2. A grinding cylinder 4 is rotatably connected to the front side of the top of the base 1. A connecting shaft 5 is fixed at the center of the inside of the grinding cylinder 4. The top of the stand plate 2 is rotatably connected to the top of the connecting shaft 5 through a swivel seat 6. A pulley 7 is fixed on the upper end of the connecting shaft 5. A drive motor 8 is installed on the outer wall of the rear end of the stand plate 2. A pulley 9 is installed on the output end of the drive motor 8. A drive belt 10 is provided between the drive motor 8 and the pulley 9. Multiple sets of grinding soft rods 11 are installed at equal intervals inside the grinding cylinder 4. Clamping components are provided on both sides of the lower end of the through groove 3.

[0024] By mounting a rotatable grinding cylinder 4 on the base 1 and installing multiple sets of detachable grinding rods 11 inside the grinding cylinder 4, the seat frame to be ground can be placed into the grinding cylinder 4. The drive motor 8 drives the pulley 7 on the connecting shaft 5 to rotate, so that the grinding cylinder 4 rotates at a constant speed under the drive of the connecting shaft 5. This allows the multiple sets of grinding rods 11 inside the grinding cylinder 4 to quickly grind the seat frame inside the grinding cylinder 4. The flexible material of the grinding rods 11 can adapt to the slight concavity and convexity of the curved surface of the seat frame, achieving uniform grinding and effectively improving grinding efficiency.

[0025] In other embodiments, the clamping assembly includes a clamping seat 13, a slot 14, a sleeve 15, a sliding column 16, a connecting plate 17, a locking block 18, a connecting rod 19, a return spring 20, and a handle 21. The clamping seats 13 are fixed on both sides below the through groove 3. The front ends of the two sets of clamping seats 13 are provided with slots 14. The opposite ends of the two sets of clamping seats 13 are fixed with sleeves 15. The sliding columns 16 are provided inside the two sets of sleeves 15. The front ends of the two sets of sliding columns 16 are connected to the locking blocks 18 through the connecting rod 19 and the connecting plate 17. The outside of the two sets of connecting rods 19 is wound with a return spring 20. The front ends of the two sets of connecting plates 17 are fixed with handles 21.

[0026] By installing two sets of clamps 13 on the upper end of the grinding cylinder 4, suitable seat frames can be placed in the slots 14 on the clamps 13. Then, by installing a movable locking block 18 at the front end of the clamps 13, the handle 21 can be pulled, causing the connecting plate 17 to move the locking block 18 and the sliding column 16 forward along the sleeve 15. The seat frame is then placed inside the slot 14. After releasing the pull on the handle 21, the return spring 20 outside the connecting rod 19 releases its elasticity and pushes the sliding column 16 backward, allowing the connecting plate 17 to quickly insert the locking block 18 into the slot 14. The locking block 18 and the slot 14 effectively fix the seat frame, making it easy to grind parts of the seat frame.

[0027] In other embodiments, a control box 12 is installed on the side of the support plate 2, and the input end of the drive motor 8 is electrically connected to the control box 12 through a wire;

[0028] This design enables the control box 12 to precisely control the speed of the drive motor 8, ensuring that the drive motor 8 can be used normally.

[0029] In other embodiments, the outer wall of the sliding column 16 is fully fitted with the inner wall of the sleeve 15, and the sliding column 16 and the sleeve 15 are slidably connected.

[0030] This design effectively prevents the slide column 16 from shaking excessively during its movement as it moves laterally within the sleeve 15, thus significantly increasing the stability of the slide column 16 during use.

[0031] In other embodiments, the inner wall of the slot 14 is provided with anti-slip texture, and the surface of the block 18 is covered with a rubber layer;

[0032] This design effectively increases the friction between the slot 14 and the block 18 and the seat frame, making it easier for the slot 14 and the block 18 to effectively fix the seat frame.

[0033] In other embodiments, the two ends of the return spring 20 are respectively connected to the outer wall of the slide column 16 and the inner wall of the sleeve 15, and the slide column 16 is elastically connected to the inner wall of the sleeve 15 through the return spring 20;

[0034] This design allows the return spring 20 outside the connecting rod 19 to continuously release a backward elastic force on the slide column 16, enabling the slide column 16 to drive the locking block 18 to quickly insert into the slot 14 on the clamp 13.

[0035] Working principle: Start the drive motor 8, which drives the grinding cylinder 4 to rotate at high speed through pulley 7, drive belt 10 and pulley 9. Place the seat frame in the slot 14 of the clamp 13, and pull the clamp 18 to fix it by pulling the handle 21. Adjust the position of the rotating seat 6 in the through slot 3 by operating the control box 12 so that the grinding soft rod 11 contacts the surface of the seat frame and grinds the surface of the seat frame evenly.

[0036] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0037] 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.
