[0002] On the modern high -speed operation automatic packing assembly line, the silk car carousel as the key component of bearing and conveying material, faces the huge load pressure and dynamic inertia challenge. In view of this, the original design has configured the speed reducer mechanism to control the carousel speed, but under heavy load condition, it is still difficult to realize the accurate positioning target. For this purpose, a set of positioning device driven by the cylinder is introduced, and the positioning device is composed of positioning block, positioning column and cylinder, a carousel machine has two positioning blocks, one on one side, and the positioning column is connected with the cylinder, the bottom of the positioning block is the concave structure, and the top of the positioning column is the conical structure, the carousel is in place, and the positioning column is lifted by the cylinder to realize positioning, aiming at making up the speed reducer mechanism limit, ensuring that the carousel can be accurately parked at the preset position when completing 180 degree circular motion.

[0003] However, in the initial stage of actual deployment, the efficiency of the carousel positioning system does not meet the expectation, mainly because the depth of the positioning groove on the positioning block is insufficient, the physical force between the carousel and the positioning column under heavy load condition is not fully considered initially, resulting in unstable positioning, secondly, the gap between the positioning block and the positioning column is too large, which weakens the positioning accuracy, causes lateral displacement and causes the positioning block to wear. The angle of the positioning groove bevel and the positioning column does not match, resulting in uneven distribution of contact points, accelerating the material fatigue and wear rate, and the original positioning block material toughness and wear resistance are limited, and cannot withstand long-term high-frequency impact load. SUMMARY

[0004] In order to solve the existing problems in the prior art, the purpose of the present application is to provide a full-automatic packing assembly line carousel positioning device, which can solve the problems of unstable and inaccurate positioning of the carousel under heavy load condition due to insufficient depth of the positioning groove and too large contact gap of the existing positioning block, make the contact surface less likely to wear, and make the angle matching more stable, and the stability is better under long-term high-frequency impact load.

[0018] Hereinafter, the present application will be further described in conjunction with the drawings and specific embodiments, it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0019] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0020] The terms "first", "second", and the like in the present application are used to distinguish similar objects, and are not used to describe a particular order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, a first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0021] As shown in Figure 1 and Figure 2 An automatic packaging line carousel positioning device, comprising positioning blocks 3 installed on both sides of the carousel, and positioning columns 2 provided on the piston rods of the air cylinders, the bottom of the positioning block 3 is provided with a downward protruding V-shaped clamp 4, the top of the positioning column 2 is provided with a V-shaped groove 5 matching the V-shaped clamp 4, and the V-shaped groove 5 at the top of the positioning column 2 is inserted into the V-shaped clamp 4 through air cylinder control to realize the position fixation of the positioning block 3.

[0022] When positioning the carousel through the carousel positioning device, the originally concave positioning block 3 is replaced by the convex V-shaped clamp structure, and the originally conical top positioning column 2 is replaced by the structure with V-shaped groove 5. When the positioning column 2 is lifted up by the air cylinder to cooperate with the positioning block 3 to position the carousel, the V-shaped groove 5 is completely matched with the V-shaped clamp 4 outside, forming a stable and tight engagement relationship, the V-shaped clamp can better accurately butt joint with the V-shaped groove structure, and the inclined surface between the V-shaped clamp 4 and the V-shaped groove 5 can better enhance the stable connection between the positioning block 3 and the positioning column 2, ensuring more accurate position fixation, effectively solving the problem of unstable and inaccurate positioning of the carousel under heavy load due to insufficient depth of the positioning groove and too large contact gap of the existing positioning block 3, making the contact surface less prone to wear, and the angle matching more stable, and the stability better under long-term high-frequency impact load.

[0023] Further improvement is that a limiting sleeve 1 is arranged outside the positioning column 2, and the positioning column 2 is limited and telescopic along the inner hole of the limiting sleeve 1.

[0024] A limiting sleeve 1 fixed by bolts is added to the existing equipment, and the positioning column 2 is located inside the limiting sleeve 1. When the piston rod of the air cylinder performs telescopic control, the positioning column 2 slides along the limiting sleeve 1. When positioning the turntable, the stability of the positioning column 2 can be further increased through the limiting sleeve 1, avoiding the situation that the positioning is unstable due to the physical force of the turntable on the positioning column 2 under the heavy load state. Generally, a chamfer is formed at the inner hole of the limiting sleeve 1 or at the turning point of one end of the positioning column 2 to facilitate the disassembly and assembly of the two.

[0025] Further improvement is that the cross-section of the positioning column 2 is of a rectangular structure, the inner hole of the limiting sleeve 1 is a square hole matching the positioning column 2, and both the positioning column 2 and the positioning block 3 are made of high-carbon steel.

[0026] The circular movable positioning column 2 driven by the air cylinder is changed to a rectangular positioning column 2, and at the same time, a limiting sleeve 1 with a square hole is added to better adapt to the limitation of the new rectangular movable positioning block 3, ensuring the tight fit and stable connection between the two, avoiding the problem that the V-shaped groove at the top of the positioning column 2 cannot be positioned due to the angle rotation during telescopic movement, increasing the contact area, and changing the material to high-carbon steel, which has higher hardness and stronger wear resistance, greatly increasing the service life, effectively solving the wear problem, improving the output, and reducing the failures. At the same time, through the above improved positioning device, the accuracy of the rotary rack positioning and the operation efficiency of the overall system are greatly improved, and it also helps to extend the service life of each component and reduce the maintenance times.

[0027] Further improvement is that the contact surface between the V-shaped chuck 4 and the V-shaped groove 5 is of a "Ji" - shaped structure.

[0028] The overall shape of the contact surface between the V-shaped chuck 4 and the V-shaped groove 5 is similar to a "Ji" - shaped structure, which can effectively increase the contact area. At the same time, through the arc angle at the bottom of the V shape, the supporting effect can also be improved, so that the stability after fitting is better.

[0029] Further improvement is that as Figure 3 shown, a threaded hole 6 recessed inward is provided at the bottom of the positioning column 2.

[0030] Through the threaded hole 6, the disassembly and assembly with the piston rod of the air cylinder are convenient, and at the same time, the angle adjustment for installation is more flexible, enabling it to accurately enter the inner hole of the limiting sleeve 1.

[0031] The above embodiments are only the preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
