Description

A refrigerant filling clamping and positioning mechanism Technical Field

[0001] This utility model relates to the technical field of refrigerant filling equipment, specifically a refrigerant filling clamping and positioning mechanism. Background Technology

[0002] On a refrigerant filling production line, after the clamping equipment releases the filling bottle, space is created as the clamping equipment moves, causing the filling bottle to tilt or move outward, thus affecting the subsequent conveying of filling bottles. In order to avoid the clamping and positioning equipment affecting the filling bottle, a refrigerant filling clamping and positioning mechanism needs to be proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a refrigerant filling clamping and positioning mechanism to solve the problem of positional deviation of the filling bottle after the clamping and positioning equipment is moved.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A refrigerant filling clamping and positioning mechanism includes a drive cylinder, a piston rod is movably connected to the output end of the drive cylinder, a connecting block is fixedly connected to the piston rod, a fixed seat is fixedly connected to the lower end of the connecting block, and a positioning clamping groove is provided on the fixed seat.

[0006] The positioning clamping groove has a storage groove on its wall, a push plate is slidably connected in the storage groove, an installation groove is provided on the wall of the storage groove, a sliding hole is provided in the installation groove, a sliding rod is slidably connected in the sliding hole, the sliding rod extends into the storage groove and is fixedly connected to the push plate, and a spring is sleeved on the sliding rod.

[0007] As a preferred embodiment of this utility model, one end of the spring is fixedly connected to the push plate, and the other end of the spring is fixedly connected to the mounting groove.

[0008] As a preferred embodiment of this utility model, the push plate extends into the positioning clamping groove.

[0009] As a preferred embodiment of this utility model, the end of the slide bar away from the push plate extends to the outside of the fixed base and is fixedly connected to the limit block.

[0010] As a preferred embodiment of this utility model, the four outer side walls of the push plate abut against the wall of the storage groove.

[0011] Compared with the prior art, the beneficial effects of the refrigerant filling clamping and positioning mechanism of this utility model are as follows: after the filling bottle is transported to the filling position by the production conveyor line, the cylinder is activated to drive the fixed seat and the positioning clamping groove. The positioning clamping groove pushes the filling bottle against the inner wall of the conveyor line for clamping and fixing. After filling is completed, the cylinder is activated to retract the fixed seat. At the same time, the spring pushes the push plate, so that the push plate abuts against the filling bottle and closes the positioning clamping groove, so that the filling bottle will not fall into the positioning clamping groove and affect the subsequent continuous filling operation.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0019] In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0020] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present invention should be understood according to the specific circumstances.

[0021] Referring to Figures 1-4, an embodiment of the present invention provides a refrigerant filling clamping and positioning mechanism, including a drive cylinder 1, a piston rod 2 movably connected to the output end of the drive cylinder 1, a connecting block 3 fixedly connected to the piston rod 2, a fixing seat 4 fixedly connected to the lower end of the connecting block 3, and a positioning clamping groove 5 provided on the fixing seat 4.

[0022] In use, the drive cylinder 1 is fixedly installed on the production line by the installation equipment, and is installed on the side directly below the filling port. Then, the filling bottle is transported to the area below the filling port on the production line. The drive cylinder 1 is activated to drive the piston rod 2 to extend outward. The piston rod 2 drives the fixed seat 4 to move through the connecting block 3. The fixed seat 4 is fitted onto the outside of the filling bottle through the positioning clamping groove 5 and pushes the filling bottle against the inner wall of the production line, thereby clamping and fixing the filling bottle, and fixing the filling bottle directly below the filling port. After filling is completed, the drive cylinder 1 is activated to drive the piston rod 2 to retract inward. The piston rod 2 drives the fixed seat 4 to move through the connecting block 3, so that the fixed seat 4 disengages and releases the fixing of the filling bottle, so that the filling bottle can be transported and replaced by the production line.

[0023] The positioning clamping groove 5 has a storage groove 6 on its groove wall. A push plate 7 is slidably connected in the storage groove 6. The storage groove 6 has an installation groove 8 on its groove wall. A sliding hole 9 is provided in the installation groove 8. A sliding rod 10 is slidably connected in the sliding hole 9. The sliding rod 10 extends into the storage groove 6 and is fixedly connected to the push plate 7. A spring 11 is sleeved on the sliding rod 10.

[0024] In use, the fixing seat 4 clamps and fixes the filling bottle through the positioning clamping groove 5. At the same time, the filling bottle supports the push plate 7, causing the push plate to retract into the storage groove 6, so as not to affect the clamping and fixing of the filling bottle. When the fixing seat 4 is retracted, the spring 11 pushes the push plate 7, and the push plate 7 will remain against the filling bottle. When the fixing seat 4 is fully retracted, the push plate 7 will be flush with the opening of the positioning clamping groove 5, thereby preventing the filling bottle from entering the positioning clamping groove 5 as the fixing seat 4 is retracted, thus avoiding affecting the conveying and replacement of the filling bottle.

[0025] One end of the spring 11 is fixedly connected to the push plate 7, and the other end of the spring 11 is fixedly connected to the mounting groove 8, so that the spring 11 can only be compressed and extended in its original position.

[0026] The push plate 7 extends into the positioning clamping groove 5 to seal the positioning clamping groove 5 and prevent filling bottles from entering when it is not in use.

[0027] The end of the slide bar 10 away from the push plate 7 extends to the outside of the fixed base 4 and is fixedly connected to the limiting block 12. The limiting block 12 pushes the slide bar 10 and the push plate 7 to pull, so as to prevent the push plate 7 from detaching from the fixed base 4 and the storage slot 6.

[0028] The four outer walls of the push plate 7 abut against the wall of the storage groove 6, so that the push plate 7 can only move parallel within the limit of the storage groove 6.

[0029] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
