Description

Technical Field

[0001] The utility model relates to a feeding slide mechanism used in an automatic production line, in particular to a long-stroke pneumatic movable slide mechanism. Background Art

[0002] In an automatic production line, such as an automatic welding production line, welding operations are usually completed by a manipulator in a sealed welding workshop. However, before welding, the workpiece to be welded needs to be positioned by a positioning fixture, and then the positioned workpiece to be welded is fed into the welding workshop to complete the welding operation. A set of automatic feeding slide mechanism that can automatically feed the workpiece to be welded that has been clamped and positioned into the welding workshop is required between the outside and inside of the welding workshop. Since the feeding stroke is relatively long, the existing automatic feeding slide mechanism uses a servo motor, a reduction gearbox for driving, and a gear-rack transmission. The existing automatic feeding slide mechanism has a high manufacturing cost, a long production cycle, and excessive product performance, and is not suitable for popularization and use in a production line where production costs need to be continuously reduced. Summary of the Invention

[0003] The purpose of the utility model is to address the defects existing in the above-mentioned prior art and provide a new type of long-stroke pneumatic movable slide mechanism, which can effectively reduce the product development cost and shorten the production cycle on the premise of meeting the production requirements.

[0004] The technical solution adopted by the utility model to achieve the above purpose is: a new type of long-stroke pneumatic movable slide mechanism, including a chassis, a cylinder, a slide rail, a slider, and a slide plate. The cylinder includes cylinder one and cylinder two. Cylinder one is fixedly installed on the upper side of one end of the chassis through fixed bracket one. Two slide rails are installed on the upper surfaces of the opposite sides in the longitudinal direction of the chassis. Multiple sliders are respectively matched with the slide rails to form a sliding connection mechanism. The slide plate is connected to the upper sides of multiple sliders through a connecting device and can move relative to the slide rails above the chassis together with the sliders. Cylinder two is installed below the slide plate through fixed bracket two (16). The piston rod one of cylinder one extends towards the side where cylinder two is located, and the piston rod two of cylinder two extends towards the side where cylinder one is located. The end of piston rod one far from cylinder one and the end of piston rod two far from cylinder two are connected through a floating connection block to form an integral structure. A roller device that can move on the upper surface of the chassis is installed at the bottom of the floating connection block.

[0005] A further technical solution of the utility model is: an external thread is provided at the end of piston rod one far from cylinder one, and a floating joint one is screwed onto the surface of the external thread section at the end of piston rod one. An external thread is also provided at the end of piston rod two far from cylinder two, and a floating joint two is screwed onto the surface of the external thread section at the end of piston rod two. Docking slots are respectively provided at both ends of the floating connection block, and floating joint one and floating joint two are respectively connected to the docking slots at both ends of the floating connection block.

[0006] A further technical solution of the utility model is that cover plates for closing the docking slots are respectively arranged on the upper and lower surfaces of the docking slots at both ends of the floating connection block.

[0007] A further technical solution of the utility model is that the roller device includes a roller bracket, a roller and a rotating shaft. The roller bracket is connected to the bottom surface of the floating connection block. Both ends of the rotating shaft are supported by the roller bracket. The roller is sleeved on the rotating shaft and positioned inside the roller bracket. When the first cylinder or the second cylinder works and the first piston rod or the second piston rod moves, the roller moves on the upper surface of the chassis.

[0008] A novel long-stroke pneumatic movable sliding table mechanism of the utility model has the following beneficial effects: by arranging two cylinders (the first cylinder and the second cylinder respectively) on the chassis, the piston rods of the two cylinders are connected through a floating connection block to form an integral structure. The movement stroke of the sliding plate installed on the upper side of the second cylinder can reach the sum of the movement strokes of the piston rods of the two cylinders, which is greatly improved compared with the driving stroke of the existing single cylinder. And a roller device is arranged on the lower side of the floating connection block, so that the piston rods of the two cylinders can move smoothly, which can meet the requirements of the automatic feeding sliding table in the automatic welding production line. By adopting the structure of the utility model, on the premise of meeting the production requirements, the product development cost can be effectively reduced and the production cycle can be shortened. Through data analysis, compared with the background technology, the development cost of the movable sliding table mechanism of the utility model is reduced by 30%, and the manufacturing cycle is shortened by 20%.

Detailed implementation manner

[0017] As Figures 1 to 6 shown, a new long - stroke pneumatic movable slide - table mechanism of the present utility model includes a chassis 1, a cylinder, a slide rail 2, a slider and a slide plate 10. The chassis 1 is of an overall long - shaped structure and is installed on the ground, and the chassis 1 is used to support the movable slide - table mechanism.

[0018] As Figures 1 to 6 shown, two slide rails 2 are respectively installed on the opposite two installation surfaces in the longitudinal direction of the chassis 1. In the figure, the two slide rails 2 are respectively installed on the upper surfaces near the edges on both sides in the longitudinal direction of the chassis 1, and the two slide rails 2 are respectively fixedly installed on the surface of the chassis 1 by screws. The cylinder includes a first cylinder 3 and a second cylinder 12. The first cylinder 3 is fixedly installed on the upper side of one end of the chassis 1 by screws and pins through the first fixed bracket 4. As shown in the figure, the first cylinder 3 is installed at the position between the two slide rails 2 on the upper left side of the chassis 1. The first fixed bracket 4 is fixedly connected to both the chassis 1 and the first cylinder 3. The slider is installed under the slide plate 10 by screws. Multiple sliders respectively cooperate with the two slide rails 2 to form a sliding connection mechanism. The slide plate 10 is fixedly connected to the upper sides of multiple sliders respectively by screws. The slide plate 10 can move relative to the slide rails 2 above the chassis 1 together with the slider. When the slider moves left and right relative to the slide rails 2, the slide plate 10 also moves left and right along with the slide rails 2.

[0019] As Figure 5 、 Figure 6As shown in the figure, the second cylinder 12 is installed below the slide plate 10 by means of the second fixing bracket 16 with screws and pins. The second fixing bracket 16 is connected to the lower part of the slide plate 10 and is also connected to the second cylinder 12. At the same time, the second cylinder 12 is also arranged at the position between the two slide rails 2 on the right side of the chassis 1. During installation, the axis of the second cylinder 12 should be basically the same as that of the first cylinder 3. The piston rod 5 of the first cylinder 3 extends towards the side where the second cylinder 12 is located, and the piston rod 9 of the second cylinder 12 extends towards the side where the first cylinder 3 is located. The end of the piston rod 5 far from the first cylinder 3 is connected to the end of the piston rod 9 far from the second cylinder 12 through a floating connection block 7 to form an integral structure. In this embodiment, the end of the piston rod 5 far from the first cylinder 3 is provided with an external thread, and the floating joint 6 is screwed onto the surface of the external thread section at the end of the piston rod 5; the end of the piston rod 9 far from the second cylinder 12 is also provided with an external thread, and the floating joint 8 is screwed onto the surface of the external thread section at the end of the piston rod 9. The two ends of the floating connection block 7 are respectively provided with docking slots. The floating joint 6 and the floating joint 8 are respectively connected to the docking slots at the two ends of the floating connection block 7. The upper and lower surfaces of the docking slots at the two ends of the floating connection block 7 are respectively provided with covers 11 for closing the docking slots. The floating joint 6, the floating joint 8, and the floating connection block 7 form a floating connection mechanism.

[0020] As Figure 6 shown, a roller device capable of moving on the upper surface of the chassis 1 is installed at the bottom of the floating connection block 7. The roller device includes a roller bracket 13, a roller 15, and a rotating shaft 14. The roller bracket 13 is connected to the bottom surface of the floating connection block 7. The two ends of the rotating shaft 14 are supported by the roller bracket 13. The roller 15 is sleeved on the rotating shaft 14 and is positioned inside the roller bracket 13. When the first cylinder 3 or the second cylinder 12 works and the piston rod 5 or the piston rod 9 moves, the roller 15 moves on the upper surface of the chassis 1. When the cylinder piston pushes and pulls, the roller 15 of the movable connection block can move on the corresponding plane of the chassis 1 to ensure the stability of the piston rod 5 and the piston rod 9 in the moving direction.

[0021] During operation, the first cylinder 3 and the second cylinder 12 intake or exhaust air simultaneously. Due to the connection of the floating connection block 7, the floating joint 6, and the floating joint 8, the slide plate 10 is driven to make a long-stroke movement. It can be used in an automatic welding production line. By controlling the first cylinder 3 and the second cylinder 12, the slide plate 10 is moved to one end. Then, the welding fixture is installed on the slide plate 10, and the workpiece to be welded is positioned and installed in the welding fixture. Then, by controlling the first cylinder 3 and the second cylinder 12, the slide plate 10 is moved into the welding workroom, and the workpiece is automatically welded by the automatic welding equipment. After welding is completed, by controlling the first cylinder 3 and the second cylinder 12 again, the slide plate 10 moves in the reverse direction to the initial position, and the workpiece can be unloaded.

[0022] The above embodiments are only preferred embodiments of the present utility model, and the structure of the present utility model is not limited to the forms listed in the above embodiments. Any modifications, equivalent replacements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
