Bus seat production welding workbench

Abstract

This utility model belongs to the field of bus seat manufacturing technology, and particularly relates to a welding workbench for bus seat production. It includes a processing table with a front clamping plate and an arc-shaped clamping plate slidably mounted on its top surface. Two side clamping plates are slidably mounted on one side of the front clamping plate. When welding the bus seat, the bus seat is placed on the processing table, and motor A is started to drive the lead screw to rotate. The rotation of the lead screw drives the first rack to move, which in turn drives the secondary gear to rotate. The rotation of the secondary gear drives the main gear to rotate. When the main gear rotates, the distance between the two base plates is adjusted through the cooperation of two connecting rods, two second connecting columns, and two first connecting columns. During the adjustment of the distance between the two base plates, the distance between the front clamping plate and the arc-shaped clamping plate is adjusted through two sliders, thereby achieving front-to-back clamping of the bus seat. Because the arc-shaped clamping plate is arc-shaped, it can conform to the back of the bus seat, resulting in a more stable clamping effect.

Description

Technical Field

[0001] This utility model belongs to the field of bus seat production technology, and in particular relates to a welding workbench for bus seat production. Background Technology

[0002] Public buses are the most common form of public transportation. Urbanization and motorization have led to a continuous increase in urban population and area, resulting in a rapid increase in demand for public transportation and requiring public transportation companies to invest in more buses. Based on the statistic of 0.6 buses per 10,000 urban residents, there are currently approximately 264,000 urban buses. This number needs to reach at least 630,000 by 2010, averaging at least 30,000 to 40,000 buses per year. Including replacements and scrapping, the average annual increase is 55,000 buses.

[0003] Existing processing tables cannot meet the processing requirements of bus seats during welding. Due to the irregular shape of bus seats, it is difficult to fix and clamp them conveniently and effectively. This difficulty in effectively fixing the bus seats affects subsequent welding work. In view of this, we propose a welding workbench for bus seat production. Utility Model Content

[0004] The purpose of this invention is to provide a welding workbench for the production of bus seats, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a welding workbench for the production of bus seats, comprising: A processing table, wherein a front clamping plate and an arc-shaped clamping plate are slidably installed on the top surface of the processing table, two side clamping plates are slidably installed on one side of the front clamping plate, a lifting plate is slidably installed on one side of the front clamping plate, and two downward pressing columns are fixedly installed on the bottom surface of the lifting plate, and a downward pressing block is fixedly installed at the bottom end of each of the two downward pressing columns. An adjustment assembly is disposed on the front clamping plate and is used to move the two side clamping plates. A lifting assembly is mounted on the front clamping plate and is used to drive the lifting plate to rise and fall; Two top grooves are formed on the top surface of the processing table. A slider is slidably installed in each of the two top grooves. Two base platforms are slidably installed on the bottom surface of the processing table. The bottom ends of the two sliders are fixedly connected to the top surfaces of the two base platforms respectively. The top ends of the two sliders are fixedly connected to the bottom surfaces of the arc-shaped clamping plate and the front clamping plate respectively. A movable component is mounted on a processing table and is used to move two base platforms.

[0006] In the above technical solution, the adjustment component further includes two side grooves, which are formed on one side of the processing table. A movable block is slidably installed in each of the two side grooves. One end of each movable block is fixedly connected to one side of each of the two side clamping plates. Two second racks are slidably installed on the other side of the front clamping plate, and a side gear is rotatably installed on the other side of the front clamping plate. The two second racks are symmetrically arranged on the other side of the front clamping plate and mesh with the side gear. When one of the second racks moves, it drives the side gear to rotate, and when the side gear rotates, it drives the other second rack to move. When the two second racks move, the distance between the two side clamping plates is adjusted by the two movable blocks, facilitating the clamping of the bus seat to the left and right sides by the two side clamping plates.

[0007] In the above technical solution, a telescopic cylinder is further fixedly installed on the other side of the front clamping plate. One end of the telescopic cylinder is fixedly connected to one end of one of the second racks, and the telescopic cylinder pushes one of the second racks to move.

[0008] In the above technical solution, the lifting assembly further includes two top plates, which are fixedly installed on the top surface of the front clamping plate. A common rotating shaft is rotatably installed between the two top plates. Multiple first movable rods are fixedly installed on the outer wall of the rotating shaft. Multiple fixed seats are fixedly installed on the top surface of the lifting plate. A second movable rod is rotatably installed in each of the multiple fixed seats. One side of each of the multiple second movable rods is rotatably connected to one side of each of the multiple first movable rods. A motor B is fixedly installed on one side of one of the top plates. One end of the output shaft of the motor B is fixedly connected to one end of the rotating shaft. When the motor B is started, it drives the rotating shaft to rotate. When the rotating shaft rotates, the lifting plate is lowered through the cooperation of the first movable rods, the second movable rods, and the fixed seats. After the lifting plate descends to a certain position, the lowering block will contact the seat cushion frame of the bus seat, so that the seat cushion frame is pressed tightly. This clamping method achieves the fixation of the bus seat through multiple surface clamping, which facilitates the subsequent welding of the bus seat.

[0009] In the above technical solution, the moving component further includes a main gear, which is rotatably mounted on the bottom surface of the processing table. Two first connecting columns are fixedly mounted on the bottom surface of the main gear, and two second connecting columns are fixedly mounted on the bottom surfaces of the two base platforms. Connecting rods are rotatably mounted on the two second connecting columns, and the other ends of the two connecting rods are rotatably mounted on the two first connecting columns respectively. When the main gear rotates, the distance between the two base platforms is adjusted by the cooperation of the two connecting rods, the two second connecting columns, and the two first connecting columns. When the distance between the two base platforms is adjusted, the distance between the front clamping plate and the arc-shaped clamping plate is adjusted by the two sliders, thereby achieving front and rear clamping of the bus seat. Since the arc-shaped clamping plate is arc-shaped, it can fit the back of the bus seat, thus making the clamping effect more stable.

[0010] In the above technical solution, the moving component further includes a secondary gear, which is rotatably mounted on the bottom surface of the processing table and meshes with the main gear. A first rack is slidably mounted on the bottom surface of the processing table and meshes with the secondary gear. When the first rack moves, it drives the secondary gear to rotate, and when the secondary gear rotates, it drives the main gear to rotate.

[0011] In the above technical solution, two mounting plates are fixedly installed on the bottom surface of the processing table, and the same lead screw is rotatably installed between the two mounting plates. The first rack is threadedly connected to the lead screw. A motor A is fixedly installed on one side of one of the mounting plates. One end of the output shaft of the motor A is fixedly connected to one end of the lead screw. When the motor A is started, it drives the lead screw to rotate. When the lead screw rotates, it will drive the first rack to move.

[0012] In the above technical solution, furthermore, multiple support legs are fixedly installed on the bottom surface of the processing table, and the surfaces of the arc-shaped clamping plate, the side clamping plate, and the lower pressure block are all provided with anti-slip textures. By setting support legs, the stability of the processing table when placed is enhanced, and by setting anti-slip textures, the anti-slip properties of the arc-shaped clamping plate, the side clamping plate, and the lower pressure block when clamping the bus seat are improved, thereby improving the stability during clamping.

[0013] The beneficial effects of this utility model are: 1. This welding workbench for bus seat production, when welding the bus seat, places the bus seat on top of the processing table, starts motor A to drive the lead screw to rotate, the lead screw rotates to drive the first rack to move, the first rack moves to drive the secondary gear to rotate, the secondary gear rotates to drive the main gear to rotate. When the main gear rotates, the distance between the two base platforms is adjusted by the cooperation of two connecting rods, two second connecting columns and two first connecting columns. When the distance between the two base platforms is adjusted, the distance between the front clamping plate and the arc-shaped clamping plate is adjusted by two sliders, thereby achieving front and rear clamping of the bus seat. Since the arc-shaped clamping plate is arc-shaped, it can fit the back of the bus seat, thus making the clamping effect more stable.

[0014] 2. The welding workbench for producing bus seats, after the bus seat is clamped by the front clamping plate and the arc-shaped clamping plate at the front and rear positions, the telescopic cylinder is activated to push one of the second racks to move. When one of the second racks moves, it drives the side gear to rotate. When the side gear rotates, it drives the other second rack to move. When the two second racks move, the distance between the two side clamping plates is adjusted by two moving blocks, so that the two side clamping plates can clamp the left and right positions of the bus seat.

[0015] 3. The welding workbench used for bus seat production clamps the bus seat on its front, back, left, and right sides. At this time, the starter motor B drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the lifting plate to descend through the cooperation of the first movable rod, the second movable rod, and the fixed seat. After the lifting plate descends to a certain position, the lower pressure block will contact the seat cushion frame of the bus seat, so that the seat cushion frame is pressed tightly. This clamping method achieves the fixation of the bus seat through clamping on multiple sides, which facilitates the subsequent welding of the bus seat. Attached Figure Description

[0026] The adjustment component includes two side slots 23, which are located on one side of the processing table 1.

By setting the support legs 25, the stability of the processing table 1 when it is placed is enhanced. By setting the anti-slip textures, the anti-slip properties of the arc-shaped clamping plate 3, the side clamping plate 4, and the lower pressure block 7 when clamping the bus seat are improved, thus improving the stability during clamping.

[0038] In use: When welding a bus seat, place the bus seat on the processing table 1, start the motor A19 to drive the lead screw 18 to rotate. When the lead screw 18 rotates, it will drive the first rack 16 to move. When the first rack 16 moves, it will drive the secondary gear 15 to rotate.

When the main gear 11 rotates, the distance between the two base platforms 10 will be adjusted by the cooperation of the two connecting rods 14, the two second connecting columns 13 and the two first connecting columns 12. When the distance between the two base platforms 10 is adjusted, the distance between the front clamping plate 2 and the arc-shaped clamping plate 3 will be adjusted by the two sliders 9, thereby achieving the front and rear clamping of the bus seat. Since the arc-shaped clamping plate 3 is arc-shaped, it can fit the back of the bus seat, so the clamping effect is more stable.

[0039] After the bus seat is clamped by the front clamping plate 2 and the arc-shaped clamping plate 3 at the front and rear positions, the telescopic cylinder 22 is activated to push one of the second racks 20 to move. When one of the second racks 20 moves, it will drive the side gear 21 to rotate. When the side gear 21 rotates, it will drive the other second rack 20 to move. When the two second racks 20 move, the distance between the two side clamping plates 4 will be adjusted by the two moving blocks 24, so that the two side clamping plates 4 can clamp the left and right positions of the bus seat.

[0040] After the bus seat is clamped on its front, back, left, and right sides, the starter motor B31 drives the rotating shaft 28 to rotate. When the rotating shaft 28 rotates, it drives the lifting plate 5 to descend through the cooperation of the first movable rod 29, the second movable rod 30, and the fixed seat 27. After the lifting plate 5 descends to a certain position, the lower pressure block 7 will contact the seat cushion frame of the bus seat, so that the seat cushion frame is pressed tightly. This clamping method achieves the fixation of the bus seat through clamping on multiple sides, which facilitates the subsequent welding of the bus seat.
