Technical Field

[0001] The utility model relates to the technical field of stop devices, in particular to a pneumatic buffer stop device which is convenient to install. Background Technique

[0002] In modern industrial production and assembly processes, production lines are often used for operation. Pallets carrying workpieces travel along the roller path driven by the roller path. When the pallet moves to a certain processing or assembly station, a stop device is needed to block the pallet so that the workpiece stays there for convenient operation. Commonly used stop devices are mostly pneumatic buffer stop devices. When it is necessary to stop the pallet, the piston rod of the cylinder is in the extended state to block and stop the pallet. When it is necessary to release it, the piston rod of the cylinder contracts to allow the pallet to pass normally.

[0003] When installing the existing pneumatic buffer stop device, it is usually fixed on the mounting frame of the roller path through a plurality of fixing bolts. This installation method is relatively cumbersome, and it is not convenient to disassemble and assemble it when repairing and replacing the pneumatic buffer stop device. Therefore, a pneumatic buffer stop device which is convenient to install is proposed. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] The present utility model provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a pneumatic buffer stopping device that is easy to install includes a stopping device body 1. A central column 8 is fixedly connected to the bottom of the stopping device body 1. A connecting plate 9 is fixedly connected to the bottom side wall of the central column 8. A limiting hole 10 is opened at the bottom of the connecting plate 9. The connecting plate 9 is a semi-circular ring structure. A fixing plate 4 is arranged below the stopping device body 1. An upper end of the fixing plate 4 is fixedly connected to a mounting seat 5. A mounting groove 6 is opened on the upper surface of the mounting seat 5. A first limiting block 18 is fixedly installed at the bottom of the inner cavity of the mounting groove 6. The first limiting block 18 is a quarter-circular ring structure. The thickness of the first limiting block 18 is equal to the thickness of the connecting plate 9. A second limiting block 19 is fixedly installed at the upper end of the first limiting block 18. The second limiting block 19 is a semi-circular ring structure. One end of the first limiting block 18 is aligned with one end of the second limiting block 19. A through hole 15 extending to the bottom of the fixing plate 4 is opened at the bottom of the inner cavity of the mounting groove 6. A limiting rod 12 is slidably installed in the through hole 15. The diameter of the limiting rod 12 is equal to the inner diameter of the limiting hole 10. A reset mechanism is connected to the bottom of the limiting rod 12.

[0021] Among them, the reset mechanism is composed of a limiting plate 13, a spring 14, a sleeve 16 and an annular plate 17. A sleeve 16 is fixedly connected to the bottom of the fixing plate 4. The sleeve 16 is coaxial with the through hole 15. A limiting plate 13 is sleeved on the outer wall of the limiting rod 12 and fixedly connected to the limiting plate 13. The limiting plate 13 is slidably installed in the sleeve 16. A spring 14 is also wound around the outer surface of the limiting rod 12. The upper end of the spring 14 is fixedly connected to the bottom of the limiting plate 13. The bottom of the spring 14 is fixedly connected to an annular plate 17. The annular plate 17 is fixedly connected to the bottom of the sleeve 16.

[0022] The spring 14 is always in a compressed state. Under the extrusion of the spring 14, the limiting plate 13 will press against the bottom of the fixed plate 4, causing the upper end of the limiting rod 12 to extend through the through hole 15 into the installation groove 6. By pulling the bottom of the limiting rod 12, the limiting rod 12 can be retracted into the through hole 15.

[0023] Wherein, the distance between the bottom of the limiting rod 12 and the limiting plate 13 is greater than the length of the sleeve 16, and the distance between the top of the limiting rod 12 and the limiting plate 13 is greater than the depth of the through hole 15.

[0024] With such a setting, the lower end of the limiting rod 12 can extend out of the bottom of the sleeve 16, and the upper end of the limiting rod 12 can extend into the installation groove 6.

[0025] Wherein, the top end of the limiting rod 12 is designed as a frustum-shaped structure.

[0026] With such a setting, it is convenient for the limiting rod 12 to be inserted into the limiting hole 10.

[0027] Wherein, a pull ring 11 is fixedly connected to the bottom of the limiting rod 12.

[0028] Through the provided pull ring 11, it is convenient for the staff to pull the limiting rod 12.

[0029] Wherein, the inner diameters of the connecting plate 9, the first limiting block 18, and the second limiting block 19 are all equal, and the outer diameters of the connecting plate 9, the first limiting block 18, and the second limiting block 19 are also all equal.

[0030] Wherein, a buffer cylinder 3 is arranged at the upper end of the stopper body 1. The end of the telescopic rod of the buffer cylinder 3 is fixedly connected with a baffle 2. An electric telescopic rod 7 is arranged inside the stopper body 1, and the end of the electric telescopic rod 7 is fixedly connected to the bottom of the buffer cylinder 3.

[0031] Through the provided electric telescopic rod 7, the height of the buffer cylinder 3 and the baffle 2 can be controlled, so as to buffer and intercept the material.

[0032] The present utility model provides a pneumatic buffer stopper that is convenient for installation. The specific working principle is as follows:

[0033] In use, the fixing plate 4 is fixed on the mounting bracket of the roller path, and then the connecting plate 9 at the bottom of the stopper body 1 is inserted into the mounting groove 6 along the notch position of the second limiting block 19. The bottom of the connecting plate 9 will squeeze the limiting rod 12 downward, causing the limiting rod 12 to shrink into the through hole 15 and compress the spring 14 in the sleeve 16. Then, the stopper body 1 is rotated by ninety degrees so that the connecting plate 9 rotates synchronously. The side wall of the connecting plate 9 will contact the first limiting block 18. At this time, the second limiting block 19 will cover the upper end of the connecting plate 9, thereby preventing the connecting plate 9 from moving up and down. At the same time, the limiting hole 10 at the bottom of the connecting plate 9 will just be aligned with the through hole 15 in the mounting groove 6. The limiting rod 12 in the through hole 15 loses the extrusion of the connecting plate 9 and will move upward under the extrusion of the spring 14 and insert into the limiting hole 10, thereby restricting the rotation of the connecting plate 9. In this way, the connecting plate 9 is fixed in the mounting groove 6, and further the stopper body 1 is fixed on the mounting seat 5. During disassembly, just pull the pull ring 11 at the bottom of the fixing plate 4 to make the limiting rod 12 disengage from the limiting hole 10, and then rotate the stopper body 1 in the reverse direction to complete the disassembly.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
