Description
General-purpose flexible gripper fixture for machining cylinders Technical Field
[0001] This utility model relates to the field of cosmetic processing, and in particular to a general-purpose flexible gripper tool for processing cylindrical objects. Background Technology
[0002] Cosmetics are widely used in daily life. At the same time, users have placed new demands on cosmetic containers. Generally, most cosmetic containers are round or cylindrical, and these types of products are typically held in place using clamps during the manufacturing process.
[0003] However, due to the round sides, there may be some movement or instability during clamping. When clamped directly, it may cause excessive local force, leading to bottle breakage. If the clamping force is reduced, it may not be able to clamp properly, and there is a risk of it falling during movement. Summary of the Invention
[0004] To solve the above-mentioned technical problems, this utility model provides a general-purpose flexible gripper tooling for machining cylinders.
[0005] The technical solution of this utility model is: a general-purpose flexible gripper fixture for machining cylinders, comprising two clamping parts arranged in pairs, and at least one clamping part is provided with a drive source, and under the drive of the drive source, the two clamping parts move closer or further apart; at least one clamping part is a flexible clamping mechanism, which includes:
[0006] A fixed plate and a movable clamping plate are connected by a flexible component, which includes:
[0007] A connecting shaft passes through both a fixed plate and a movable clamping plate, and when an external force is applied, the fixed plate and the movable clamping plate rotate around the connecting shaft.
[0008] A buffer elastic element is disposed between a fixed plate and a movable clamping plate. The direction of the force exerted by the buffer elastic element is perpendicular to the connecting shaft. In the initial state, the fixed plate and the movable clamping plate are arranged parallel to each other.
[0009] Furthermore, the buffer elastic element can be any one of a spring, torsion spring, elastic band, or elastic column. Generally, a spring can be placed between the two contact surfaces, which can achieve automatic reset. In the initial state, the two surfaces are parallel under the elastic force of the buffer element. When the movable pressing plates come into contact with the product, they resist the elastic force and rotate to ensure the pressing effect. When they are not in contact with the product, they reset again under the action of the elastic force.
[0010] Furthermore, a movable connecting plate is provided between the fixed plate and the movable clamping plate. The fixed plate and the movable connecting plate are connected by a flexible component, and the movable connecting plate and the movable clamping plate are connected by a flexible component. The two flexible components ensure that the angle changes are more flexible and adaptable to different clamping effects.
[0011] Furthermore, the movable clamping plate is configured to cooperate with at least one product. That is, one movable clamping plate can clamp one product, or one movable clamping plate can clamp two or more products. Generally speaking, it is recommended to clamp two products at a time.
[0012] Furthermore, a rotating sleeve is provided on the outside of the connecting shaft. The rotating sleeve ensures more flexible rotation.
[0013] Furthermore, one of the two clamping parts is fixedly installed, while the other is installed at the drive end of the drive source, which is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. A drive rod is used to achieve clamping through a unidirectional movement.
[0014] Furthermore, the driving source is a parallel pneumatic gripper, which has two driving ends, each with two clamping parts. Clamping is achieved through a single parallel pneumatic gripper.
[0015] Furthermore, when one clamping part is a rigid clamping mechanism, the rigid clamping mechanism is a rigid clamping plate, and the other clamping part is a flexible clamping mechanism. The product is directly clamped by the rigid clamping plate, and the rigid clamping mechanism and the flexible clamping mechanism work together to clamp the product.
[0016] Furthermore, both clamping parts are flexible clamps.
[0017] Furthermore, the clamping surface of the clamping part is a plane or a groove;
[0018] When the clamping surface is a plane, an anti-slip layer is installed on that plane;
[0019] When the clamping surface is a groove, the groove is designed to mate with the product. This mating design achieves stable clamping, and the addition of an anti-slip layer ensures stable clamping. For example, a silicone or rubber layer can be used, and the groove can also be a V-groove.
[0020] Furthermore, the flexible component also includes a rotating connector and a rotating connecting groove that mate with the connecting shaft. The rotating connector is disposed within the rotating connecting groove, and the connecting shaft passes through both the rotating connector and the rotating connecting groove. The size of the rotating connecting groove is larger than that of the rotating connector. This allows rotation to occur within the rotating connecting groove, ensuring smooth rotation, while the sidewalls of the connecting groove also provide a limiting effect.
[0021] The beneficial technical effects of this utility model are that, by incorporating a flexible component, when the clamping part contacts the product, the rotation of the connecting shaft achieves flexible clamping of the product. Simultaneously, the buffer elastic element ensures compression. When released, the buffer elastic element resets, aligning the clamping part in a horizontal position, facilitating the next clamping operation. This flexible gripper fixture can adapt to different product sizes, improving fixture efficiency and saving processing costs. Furthermore, this fixture has a simple structure and novel design, ensuring its service life and reducing tooling waste. Attached Figure Description

[0032] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0033] Referring to Figures 1-5, the general-purpose flexible gripper fixture for machining cylinders includes:
[0034] It includes two clamping parts 1 arranged in pairs, and at least one clamping part 1 is provided with a driving source 2, and the two clamping parts 1 move closer or further apart under the drive of the driving source 2; at least one clamping part 1 is a flexible clamping clamp, which includes:
[0035] The fixed plate 4 and the movable clamping plate 5 are connected by a flexible component 3, which includes:
[0036] The connecting shaft 31 passes through both the fixed plate 4 and the movable clamping plate 5, and when an external force is applied, the fixed plate 4 and the movable clamping plate rotate around the connecting shaft 31.
[0037] The buffer elastic element 32 is disposed between the fixed plate 4 and the movable clamping plate 5. The direction of the force of the buffer elastic element 32 is perpendicular to the connecting shaft 31. In the initial state, the fixed plate 4 and the movable clamping plate 5 are arranged in parallel.
[0038] Furthermore, the buffer elastic element 32 can be any one of a spring, torsion spring, elastic band, or elastic column. Generally, a spring can be placed between the two contact surfaces, which can achieve automatic reset. In the initial state, the two are parallel under the elastic force of the elastic buffer element. When the movable pressing plates 5 come into contact with the product, they resist the elastic force and rotate to ensure the pressing effect. When they are not in contact with the product, they reset again under the action of the elastic force.
[0039] Furthermore, a movable connecting plate 6 is provided between the fixed plate 4 and the movable clamping plate 5. The fixed plate 4 and the movable connecting plate 6 are connected by a flexible component 3, and the movable connecting plate 6 and the movable clamping plate 5 are connected by the flexible component 3. The two flexible components 3 ensure that the angle changes are more flexible and adaptable to different clamping effects.
[0040] Furthermore, the movable clamping plate 5 is configured to cooperate with at least one product. That is, one movable clamping plate 5 can clamp one product, or one movable clamping plate 5 can clamp two or more products. Generally speaking, it is recommended to clamp two products at a time.
[0041] Furthermore, a rotating sleeve 35 is provided on the outer side of the connecting shaft 31. The rotating sleeve 35 ensures more flexible rotation.
[0042] Furthermore, one of the two clamping parts 1 is fixedly installed, while the other is installed at the drive end of the drive source 2, which is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. A drive rod is then used to achieve clamping through a one-way movement mechanism.
[0043] Furthermore, the drive source 2 is a parallel pneumatic gripper, which has two drive ends, each with a clamping part 1. Clamping is achieved through a single parallel pneumatic gripper.
[0044] Furthermore, when one clamping part 1 is a rigid clamping device, the rigid clamping device is a rigid clamping plate, and the other clamping part 1 is a flexible clamping device. The product is directly clamped by the rigid clamping plate, and the rigid clamping device and the flexible clamping device work together to clamp the product.
[0045] Furthermore, both clamping parts 1 are flexible clamps.
[0046] Furthermore, the clamping surface of the clamping part 1 is a plane or a groove;
[0047] When the clamping surface is a plane, an anti-slip layer is installed on that plane;
[0048] When the clamping surface is a groove, the groove is designed to mate with the product. This mating design achieves stable clamping, and the addition of an anti-slip layer ensures stable clamping. For example, a silicone or rubber layer can be used, and the groove can also be a V-groove.
[0049] Furthermore, the flexible component 3 also includes a rotating connector 33 and a rotating connecting groove 34 that cooperate with the connecting shaft 31. The rotating connector 33 is disposed within the rotating connecting groove 34, and the connecting shaft 31 passes through both the rotating connector 33 and the rotating connecting groove 34. The size of the rotating connecting groove 34 is larger than that of the rotating connector 33. This allows rotation to occur within the rotating connecting groove 34, ensuring smooth rotation, while the sidewall of the connecting groove can also provide a limiting effect.
[0050] By incorporating the flexible component 3, when the clamping part 1 contacts the product, the rotation of the connecting shaft 31 achieves flexible clamping of the product. Simultaneously, the buffer elastic element 32 ensures compression. When released, the buffer elastic element 32 resets, placing the clamping part 1 in a horizontal position, facilitating the next clamping operation. This flexible gripper fixture can adapt to different product sizes, improving fixture efficiency and saving processing costs. Furthermore, this fixture has a simple structure and novel design, ensuring its service life and reducing tooling waste.
[0051] Referring to Figures 1-4, it is recommended to use a parallel pneumatic gripper, which has two drive ends, each with a clamping part 1.
[0052] Furthermore, one clamping part is rigidly clamped, that is, a rigid clamping plate is directly installed;
[0053] The other is a flexible clamping mechanism, which includes a fixed plate, a movable connecting plate, and a movable clamping plate, with each movable clamping plate working together to clamp two products;
[0054] For example, typical lipstick manufacturing uses a four-station product fixture. The product has a certain amount of movement within the station. After processing, the product needs to be clamped and moved. Originally, four cylinders were used for clamping. Moreover, because the product has a certain amount of movement, it can also lead to uneven force, causing the product to fall.
[0055] When using this fixture, the two clamping parts are close together, and the rigid clamping plate contacts one side of the product. At this time, the movable clamping plate on the other side also clamps the product. Due to the action of the connecting shaft and the buffer elastic element, it can perform other buffer clamping functions. At the same time, with the change of angle, it can ensure stable clamping of the product.
[0056] Driven by the moving mechanism, it is moved to other parts or the next workstation;
[0057] When the product is released, the buffer elastic element recovers under its own elasticity, restoring the movable clamping plate to its initial position, thus achieving automatic recovery.
[0058] If the springback fails to return in time, simply remove the connecting shaft and replace it with another replacement part to restore the elasticity. The structure is simple and reliable, and the subsequent maintenance cost is extremely low.
[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
