A diamond-shaped pin is fixedly connected to one corner of the top of the movable plate, and a cylindrical pin is fixedly connected to the other corner of the top of the movable plate.

[0004] When the existing cylinder lifting and positioning mechanism lifts a spherical workpiece, the workpiece will shake and collide inside the lifting chamber, causing dents and damage to its outer surface, which will affect the subsequent processing of its outer surface by the processing equipment. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in existing cylinder lifting and positioning mechanisms, when lifting spherical workpieces, the spherical workpieces shake and collide inside the lifting chamber, causing dents and damage to their outer surface, which affects the subsequent processing of their outer surface by the processing equipment. Therefore, a cylinder lifting and positioning structure is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cylinder lifting and positioning structure, comprising a drive cylinder, a lifting plate, limit rods, a mounting base, and a limiting chamber. The output end of the drive cylinder is fixedly installed at the center of the bottom surface of the lifting plate. One end of each of the four limit rods is fixedly installed at the four corners of the bottom surface of the lifting plate, and the other ends of the four limit rods are movably engaged inside the limiting chamber. A cargo compartment is provided on the top surface of the lifting plate. Movable rods are symmetrically fixedly installed on the top of the lifting plate. One end of each of the two movable rods is movably engaged at both ends of the bottom surface of the cargo compartment. A feeding ramp is symmetrically opened on the top surface of the cargo compartment, and several circular cargo slots are symmetrically opened on one side of the feeding ramp.

[0007] Preferably, a lower pressure plate is fixedly installed on both sides of the cargo compartment, and a ballast rod is provided at both ends of the cargo compartment. One end of the ballast rod is located directly above the lower pressure plate, and a spring is movably sleeved on the outer side of the movable rod.

[0008] Preferably, a plurality of top rods are symmetrically installed on the top surface of the lifting plate, and the plurality of top rods are arranged below the circular loading trough.

[0011] Preferably, the protective partition has limit holes evenly spaced at its four corners, and a protective sleeve is fixedly installed inside the limit holes.

[0012] Preferably, the limiting rod extends through the interior of the protective sleeve.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the spherical workpiece is stuck inside the circular loading groove to prevent the spherical workpieces from colliding with each other, thereby protecting the flatness of the outer surface of the spherical workpiece. In addition, during the movement of the lifting plate, the four limiting rods will constrain the movement trajectory of the lifting plate, so that the lifting plate can always maintain a straight line movement in the vertical direction.

[0015] 2. In this utility model, the ballast rod presses the lower pressure plate, causing the cargo compartment compression spring to move downwards. The top rod passes through the lower end of the circular cargo groove, pushing out the spherical workpiece that is stuck inside the circular cargo groove. The spherical workpiece is pushed to one side of the unloading slope and rolls down onto the worktable located at a higher position under the action of gravity, completing the unloading operation. There is no need to set up other unloading devices for auxiliary unloading, reducing the processing cost of spherical workpieces. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this utility model provides a cylinder lifting and positioning structure, including a drive cylinder 1, a lifting plate 2, limit rods 3, a mounting base 11, and a limiting chamber 5. The output end of the drive cylinder 1 is fixedly installed at the center of the bottom surface of the lifting plate 2. One end of each of the four limit rods 3 is fixedly installed at the four corners of the bottom surface of the lifting plate 2, and the other end of each of the four limit rods 3 is movably engaged inside the limiting chamber 5. A loading chamber 4 is provided on the top surface of the lifting plate 2. Movable rods 21 are symmetrically fixedly installed on the top of the lifting plate 2. One end of each of the two movable rods 21 is movably engaged at both ends of the bottom surface of the loading chamber 4. A feeding ramp 41 is symmetrically opened on the top surface of the loading chamber 4, and several circular loading slots 42 are symmetrically opened on one side of the feeding ramp 41.

[0025] The specific settings and functions of this embodiment are described below. The spherical workpiece to be transported is placed inside the circular loading slot 42 in the loading compartment 4. Then, the drive cylinder 1 is activated, which drives the lifting plate 2 and the loading compartment 4 installed on the upper end of the lifting plate 2 to move to the specified height, completing the lifting and transport of the spherical workpiece. During the lifting process, the spherical workpiece is stuck inside the circular loading slot 42, which prevents the spherical workpieces from colliding with each other, thereby protecting the flatness of the outer surface of the spherical workpiece. In addition, during the movement of the lifting plate 2, the four limit rods 3 will constrain the movement trajectory of the lifting plate 2, so that the lifting plate 2 can always maintain a straight line movement in the vertical direction. Example

[0026] like Figure 1-5 As shown, this utility model provides a cylinder lifting and positioning structure, including a drive cylinder 1, a lifting plate 2, limiting rods 3, a mounting base 11, and a limiting chamber 5. The output end of the drive cylinder 1 is fixedly installed at the center of the bottom surface of the lifting plate 2. One end of each of the four limiting rods 3 is fixedly installed at the four corners of the bottom surface of the lifting plate 2, and the other ends of the four limiting rods 3 are movably engaged inside the limiting chamber 5. A loading chamber 4 is provided on the top surface of the lifting plate 2. Movable rods 21 are symmetrically fixedly installed on the top of the lifting plate 2. One end of each of the two movable rods 21 is movably engaged at both ends of the bottom surface of the loading chamber 4. A feeding ramp 41 is symmetrically opened on the top surface of the loading chamber 4, and several feeding ramps 41 are symmetrically opened on one side of the feeding ramp 41. A circular cargo compartment 42 has a lower pressure plate 43 fixedly installed on both sides of the cargo compartment 4. A ballast rod 6 is set at both ends of the cargo compartment 4. One end of the ballast rod 6 is set directly above the lower pressure plate 43. A spring 211 is movably sleeved on the outside of the movable rod 21. Several top-mounting rods 22 are symmetrically installed on the top surface of the lifting plate 2. Several top-mounting rods 22 are set below the circular cargo compartment 42. A soft sleeve 221 is movably sleeved on the top end of the top-mounting rod 22. A protective partition 7 is set between the lifting plate 2 and the driving cylinder 1. Limiting through holes 71 are evenly opened at the four corners of the protective partition 7. A protective sleeve 72 is fixedly installed inside the limiting through hole 71. The limiting rod 3 moves through the inside of the protective sleeve 72.

[0027] The overall effect of this embodiment is that when the cargo compartment 4 moves to a designated height, one end of the two ballast rods 6 presses down on the lower pressure plate 43, causing the cargo compartment 4 to compress the spring 211 downwards. The top rod 22 passes through the lower end of the circular cargo groove 42, pushing out the spherical workpiece that is stuck inside the circular cargo groove 42. The spherical workpiece is pushed to one side of the unloading slope 41, and the spherical workpiece rolls down onto the worktable located at a higher position under the action of gravity, completing the unloading operation. There is no need to set up other unloading devices to assist in unloading, reducing the processing cost of the spherical workpiece. In addition, by movably sleeved with a soft sleeve 221 at the top of the top rod 22, the bottom surface of the spherical workpiece is prevented from being scratched by the top rod 22 when it is unloading. After the lifting operation is completed, the drive cylinder 1 drives the lifting plate 2 to reset, and the spring 211 lifts the cargo compartment 4, completing the reset operation.

[0028] The method of use and working principle of this device: Place the spherical workpiece to be transported inside the circular loading trough 42 in the loading chamber 4, and then start the drive cylinder 1. The drive cylinder 1 drives the lifting plate 2 and the loading chamber 4 installed on the upper end of the lifting plate 2 to move to the designated height, completing the lifting and conveying of the spherical workpiece. When the loading chamber 4 moves to the designated height, one end of the two ballast rods 6 presses down on the lower pressure plate 43, causing the loading chamber 4 to move downward. The top rod 22 passes through the lower end of the circular loading trough 42 and pushes out the spherical workpiece stuck inside the circular loading trough 42. The spherical workpiece is pushed to one side of the unloading slope 41. Under the action of gravity, the spherical workpiece rolls down to the worktable located at the higher position, completing the unloading operation.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
