Description

Technical Field

[0001] This utility model relates to the field of electrochemical processing, and in particular to a gripping device for gripping parts in an acidic chemical solution. Background Technology

[0002] In the industrial production of anodizing surface treatment, parts are hung using specific fixtures or bound to racks with aluminum wire before being immersed in an acidic solution for electrochemical treatment. During the process of entering and exiting the chemical bath, parts or fixtures may detach and sink to the bottom due to mutual shaking or unstable clamping. Industrial chemical baths are typically quite deep, making it difficult for human hands to retrieve parts from the bottom.

[0003] Using ordinary metal tools, such as hook-like rods, to pick up parts is inaccurate, and parts are prone to falling during the lifting process, which is very inconvenient. Therefore, there is an urgent need to propose a solution to these problems. Utility Model Content

[0004] The purpose of this invention is to provide a gripping device for gripping parts in acidic chemical solutions, which solves the problems of low gripping accuracy and low gripping stability of existing gripping tools.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A gripping device for grasping parts in an acidic chemical solution includes a support rod and a mechanical claw. The support rod has an operating hole extending along its length. The mechanical claw includes a base and multiple flexible fixing members. The base can enter the operating hole. The multiple flexible fixing members are spaced apart on the base circumferentially, and their extension directions are at an angle to the axial direction of the support rod. The flexible fixing members are used to fix the parts in the acidic chemical solution. The gripping device also includes an operating member. One end of the operating member is connected to the base, and the other end can pass through the operating hole. The flexible fixing member has a gripping state and a releasing state. When the flexible fixing member is in the gripping state, the operating member pulls the base towards the operating hole. The operating hole compresses the flexible fixing member, causing it to close towards the axis of the operating hole to grasp the part. When the flexible fixing member is in the releasing state, the base exits the operating hole, and the flexible fixing member unfolds.

[0007] Optionally, the flexible fastener includes a connecting part and a fixing part connected to each other. The connecting part is installed on the base, and the length direction of the connecting part is set at an angle to the axial direction of the support rod. The fixing part is used to fix the part.

[0008] Optionally, the length direction of the fixing part is parallel to the axial direction of the operating hole.

[0009] Optionally, a groove is provided at the end of the fixing part away from the connecting part.

[0010] Optionally, the base includes a seat body and a screw portion. A plurality of flexible fixing members are spaced apart on the seat body circumferentially. The screw portion is connected to one end of the seat body and is provided with an external thread. One end of the operating member is sleeved on the screw portion. The gripping device also includes a fastener. The fastener has a threaded hole. The fastener is threadedly engaged with the screw portion and can press one end of the operating member against the seat body.

[0011] Optionally, the base further includes an annular portion connected to the outer periphery of the base body, and a plurality of flexible fasteners are spaced apart on the annular portion along the circumferential direction of the annular portion.

[0016] The beneficial effects of this utility model are:

[0017] This invention discloses a gripping device for grasping parts in an acidic chemical solution. The gripping device includes a support rod and a mechanical claw. The support rod has an operating hole extending through its length. The mechanical claw includes a base and multiple flexible fixing members. The base can enter the operating hole. The multiple flexible fixing members are spaced apart on the base circumferentially, and the extension direction of the flexible fixing members is at an angle to the axial direction of the support rod. The flexible fixing members are used to fix the parts in the acidic chemical solution. The gripping device also includes an operating member. One end of the operating member is connected to the base, and the other end can pass through the operating hole. The flexible fixing member has a gripping state and a releasing state. When the flexible fixing member is in the gripping state, the operating member pulls the base towards the operating hole. The operating hole presses the flexible fixing member, causing the flexible fixing member to close towards the axis of the operating hole to grasp the part. When the flexible fixing member is in the releasing state, the base exits the operating hole, and the flexible fixing member unfolds. This embodiment features a gripping device. The mechanical gripper of the gripping device consists of a base and flexible fixing components. Multiple flexible fixing components are spaced apart along the circumference of the base. When gripping parts in an acidic chemical solution, the operating component pulls the base towards the operating hole until the operating hole abuts against the flexible fixing component. Since the extension direction of the flexible fixing component is at an angle to the axis of the support rod, the operating hole forces the flexible fixing component to close towards the axis of the operating hole, thereby allowing the flexible fixing component to grip the part from all sides with high gripping accuracy. At the same time, during the movement of the gripped part, the operating component can be tightened to firmly fix the flexible fixing component in place, preventing the part from falling and ensuring high gripping stability. Furthermore, the pulling force on the operating component can be controlled at will for parts of different weights, making the gripping device highly operable and improving its reliability and user satisfaction.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0026] This embodiment proposes a gripping device for gripping parts in an acidic chemical solution, which solves the problem that the gripping accuracy and gripping stability of existing gripping tools are both low.

[0027] like Figures 1-2As shown, a gripping device for grasping parts in an acidic chemical solution includes a support rod 1 and a mechanical claw 2. The support rod 1 has an operating hole extending through it along its length. The mechanical claw 2 includes a base 21 and multiple flexible fixing members 22. The base 21 can enter the operating hole. The multiple flexible fixing members 22 are spaced apart on the base 21 circumferentially, and the extension direction of the flexible fixing members 22 is at an angle to the axial direction of the support rod 1. The flexible fixing members 22 are used to fix the parts in the acidic chemical solution. The gripping device also includes an operating member 4. One end of the operating member 4 is connected to the base 21, and the other end can pass through the operating hole. The flexible fixing members 22 have a gripping state and a releasing state. When the flexible fixing members 22 are in the gripping state, the operating member 4 pulls the base 21 to move towards the operating hole. The operating hole presses the flexible fixing members 22, causing the flexible fixing members 22 to close towards the axis of the operating hole to grasp the parts. When the flexible fixing members 22 are in the releasing state, the base 21 exits the operating hole, and the flexible fixing members 22 unfold.

[0028] Understandably, when a part falls to the bottom of an acidic chemical solution tank, it needs to be retrieved using tools. Existing methods for grasping parts have low accuracy and stability. Therefore, this embodiment addresses this by providing a grasping device. The mechanical gripper 2 of the grasping device consists of a base 21 and flexible fixing members 22. Multiple flexible fixing members 22 are spaced apart circumferentially around the base 21. When it is necessary to grasp a part in the acidic chemical solution, the operating member 4 can pull the base 21 towards the operating hole until the operating hole abuts against the flexible fixing member 22. Due to the extension direction of the flexible fixing member 22... The operating hole is set at an angle to the axis of the support rod 1. The operating hole forces the flexible fixing member 22 to close towards the axis of the operating hole, so that the flexible fixing member 22 can grasp the part from all sides with high grasping accuracy. At the same time, during the movement of the grasped part, the operating member 4 can be tightened to firmly fix the part with the flexible fixing member 22, making it less likely for the part to fall off and the grasping stability is high. Furthermore, the pulling force on the operating member 4 can be controlled at will for parts of different weights, making the grasping device highly operable and improving the reliability of the grasping device and user satisfaction.

[0029] For example, the operating element 4 is a metal wire. This arrangement facilitates the pulling of the operating element 4, improving the operability of the gripping device.

[0030] Optionally, the flexible fastener 22 includes a connecting portion 221 and a fixing portion 222 connected to each other. The connecting portion 221 is mounted on the base 21, and the length direction of the connecting portion 221 is set at an angle to the axial direction of the support rod 1. The fixing portion 222 is used to fix the parts. By connecting the base 21 and the fixing portion 222 through the connecting portion 221, the gripping range of the flexible fastener 22 can be increased, thereby improving the reliability of the gripping device.

[0031] Optionally, the length direction of the fixing part 222 is parallel to the axial direction of the operating hole. Understandably, when the connecting part 221 closes to the axis of the operating hole, the fixing part 222, which is parallel to the axial direction of the operating hole, can clamp the part, thereby increasing the fixing strength of the part and preventing the part from falling, thus improving the stability of the part gripping.

[0032] Optionally, a groove 2221 is provided at the end of the fixing part 222 away from the connecting part 221. This arrangement can increase the friction at one end of the fixing part 222, thereby enabling the fixing part 222 to grip the part in a forked manner, increasing the contact points with the part, and thus improving the reliability of part gripping.

[0033] For example, the groove 2221 is a V-shaped groove. The V-shaped groove 2221 has two sharp corners, which further enhances the gripping ability of the fixing part 222 on the part and improves the reliability of the gripping device.

[0034] Optionally, the base 21 includes a seat body 211 and a screw portion 212. Multiple flexible fasteners 22 are spaced apart around the seat body 211. The screw portion 212 is connected to one end of the seat body 211 and has external threads. One end of the operating member 4 is fitted onto the screw portion 212. The gripping device also includes a fastener 3 with a threaded hole. The fastener 3 is threadedly engaged with the screw portion 212 and can press one end of the operating member 4 against the seat body 211. This arrangement, through the engagement of the screw portion 212 and the fastener 3, clamps one end of the operating member 4 onto the seat body 211. The structure is simple and reliable, improving the connection strength between the base 21 and the operating member 4. Furthermore, when the acidic chemical solution tank is deep or shallow, different lengths of support rods 1 and operating members 4 are required. This arrangement allows for easy replacement of the operating member 4 by tightening the fastener 3 at any time, improving the ease of assembly and disassembly of the gripping device.

[0035] For example, fastener 3 is a nut. This arrangement reduces the cost of fastener 3 and improves its reliability, thereby enhancing the economy and durability of the gripping device.

[0036] Optionally, the base 21 also includes an annular portion 213, which is connected to the outer periphery of the base body 211. Multiple flexible fasteners 22 are spaced apart along the circumference of the annular portion 213. The annular portion 213 allows the flexible fasteners 22 to be arranged at arbitrary intervals, enabling users to freely adjust the number of flexible fasteners 22, thus improving the structural rationality of the gripping device and user satisfaction.

[0037] Optionally, the fastener 3 has a through hole along the axial direction of the screw portion 212, through which the operating member 4 can pass. This arrangement reduces interference between the screw portion 212 and the operating hole, thereby improving the smoothness of movement of the operating member 4. In addition, this arrangement allows the operating member 4 to be passed through the through hole first, then bent into a shape that fits the screw portion 212, and then fitted onto the screw portion 212. When the fastener 3 is tightened, the fastener 3 moves toward the seat 211, thereby slowly pressing the operating member 4 against the seat 211, thus improving the fixing strength of the operating member 4.

[0038] Optionally, the flexible fastener 22 is plate-shaped. This arrangement increases the contact area between the flexible fastener 22 and the part, thereby improving the gripping stability of the flexible fastener 22.

[0039] Optionally, the support rod 1 is cylindrical. This design makes the surface of the support rod 1 smoother, avoiding scratching parts that have not sunk to the bottom of the acidic chemical solution tank, and improving the reliability of the gripping device.

[0040] Optionally, the mechanical gripper 2, the operating component 4, and the support rod 1 are all made of aluminum alloy or titanium alloy. Understandably, when using ordinary metal tools to pick up parts, the acidic solution in the tank will corrode the tools, causing them to become damaged after a certain period of use. Simultaneously, the corroded metal residue will contaminate the solution in the tank, rendering it unusable. In this embodiment, the mechanical gripper 2, the operating component 4, and the support rod 1 are all made of aluminum alloy or titanium alloy. These components have excellent corrosion resistance in acidic solutions, allowing for long-term use without frequent replacement, thus improving the reliability of the gripping device.

[0041] Of course, in other embodiments, the mechanical claw 2, the operating component 4 and the support rod 1 can also be made of other components resistant to acid solution corrosion. They can be set as needed according to the actual application scenario, and no further restrictions are imposed here.

[0042] The operation process of the gripping device in this embodiment is as follows:

[0043] First, observe the location where the parts fell, and select support rods 1 and operating parts 4 of different lengths as needed according to the depth of the acidic chemical solution tank.

[0044] Connect one end of the mechanical gripper 2 to one end of the operating member 4, and pass the other end of the operating member 4 through the operating hole.

[0045] Hold the support rod 1 and extend the mechanical claw 2 to the vicinity of the part, so that the flexible fixing part 22 covers the part. At the same time, pull out the operating part 4 and press down the support rod 1 to bring the base 21 close to the operating hole until the operating hole presses the flexible fixing part 22 to grab the part.

[0046] Hold the support rod 1 and move it upward. During the upward movement, tighten the operating part 4 to prevent the part from falling. After the part is removed from the acidic chemical solution tank, loosen the operating part 4 to open the flexible fixing part 22 and put the part down.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
