Abstract
Description
Technical Field
[0001] This utility model relates to the field of surface treatment technology, and in particular to a tooling for mounting small button-like hard anodized materials. Background Technology
[0002] Small button-type hard anodizing fixtures are mainly used for the electrical connection and physical mounting of small metal parts during the hard anodizing process. Because small button-like workpieces are typically small, finely shaped, and numerous, higher demands are placed on the clamping stability, conductivity reliability, and ease of operation of the fixture during surface treatment. The anodizing process relies on stable current conduction and contact interfaces; poor mounting will directly affect the thickness, uniformity, and adhesion of the oxide layer on the workpiece surface, and may even lead to the scrapping of the workpiece.
[0003] However, traditional clamping structures lack flexibility, are complex to operate manually, and are not conducive to the rapid positioning and clamping of small workpieces, which can easily lead to low efficiency and unstable operation. In addition, conventional fixtures are mostly rigid structures and cannot automatically adjust the clamping force according to the workpiece size tolerance, which can easily lead to insecure clamping or excessive clamping force that damages the workpiece and affects the clamping stability of the workpiece.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication 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.
[0047] like Figs. 1 to 5 As shown: A small button-like rigid anode mounting fixture includes: a hanger 1 and multiple clamping components 2 sequentially arranged on the hanger 1;
[0048] Each clamping assembly 2 includes a pair of clamping arms 21 arranged in a V-shape. One end of the clamping arm 21 is connected to the hanger 1, and the other end is provided with a pair of jaws 22 for clamping small button-like workpieces 01.
[0049] The clamping arms 21 have an elastic structure. They are in an open state when no external force is applied, and when force is applied, they come together so that the two sides of the jaws 22 cross and form a clamping state. The clamping force is applied to the jaws 22 by its own elastic restoring force to clamp the small button-like workpiece 01.
[0050] By setting a pair of V-shaped clamping arms 21 and a clamping claw 22 at the end of the clamping arms 21, the size and structure of the small button-like workpiece 01 can be accurately aligned to achieve stable clamping, overcoming the operational difficulties of traditional hooking or pressing methods when clamping small workpieces.
[0051] The clamping arm 21 adopts an elastic structure design and has self-adaptive clamping capability. It can stably clamp small button-like workpieces 01 with different dimensional tolerances, effectively preventing the workpiece from loosening or shifting during the anodizing process and ensuring process stability.
[0052] As a preferred embodiment of the above, the gripper 22 includes a first locking strip 221 and a second locking strip 222 respectively disposed on both sides, and the first locking strip 221 and the second locking strip 222 are structurally staggered.
[0053] The first clip 221 and the second clip 222 are symmetrically arranged in cross sections, and each is provided with a first clamping part 221a and a second clamping part 221b that are connected to each other. The two first clamping parts 221a are arranged opposite each other and are inclined inward, and the two second clamping parts 221b are arranged opposite each other and are open outward.
[0054] When the clamping arm 21 is in a closed state under force, the second clamping bar 222 is inserted into the gap formed between the two first clamping bars 221, forming a receiving space 223 for clamping small button-like workpieces 01.
[0055] In use, press the V-shaped clamping arm 21 to insert the second clamping strip 222 into the gap formed between the two first clamping strips 221, and place the small button-like workpiece 01 into the receiving space 223. Release the hand, and the small button-like workpiece 01 will be clamped under the elastic restoring force of the V-shaped clamping arm 21. The operator only needs to press the V-shaped clamping arm 21, put the workpiece into the clamping space and release the hand to complete the clamping process. This eliminates the cumbersome alignment, manual tightening and clamping steps in traditional fixtures, greatly improves clamping efficiency, and is especially suitable for batch or automated production.
[0056] The "inward tilt + outward opening" shape of the clamping part allows the jaws 22 to form local point or line contact with the workpiece, avoiding large-area obstruction, expanding the effective processing area of the workpiece, which is conducive to the uniform distribution of current and improves the density and uniformity of the anodized layer.
[0057] The gripper 22 closes under the elastic restoring force of the gripping arm 21, and at the same time forms a three-dimensional clamping structure through the "geometric interlocking of the two clamping bars", which effectively prevents the workpiece from shifting or loosening due to electrolyte impact or bubble disturbance during the anodizing process, and enhances the stability of the workpiece during the processing.
[0058] The first clamping bar 221 and the second clamping bar 222 are symmetrically arranged in structure, and the accommodating space 223 is adaptively formed by the gap of the clamping jaws 22, which can accommodate small button-like workpieces 01 with certain dimensional tolerances or different diameter specifications, thus having a wider range of applications and reducing the frequency of tooling changes.
[0059] In the embodiments, the number of first card strips 221 is at least two, and the number of second card strips 222 is one. In this embodiment, the number of first card strips 221 is two, and the number of second card strips 222 is one. The clamping state forms three clamping points, which minimizes the number of contact points and is the most secure. Alternatively, the number of first card strips 221 and second card strips 222 can be at other intervals, all of which are within the protection scope of this application.
[0060] The clamping arm 21 is connected to the first clamping bar 221, and the first clamping bar 221 and the second clamping bar 222 are provided with rounded corners 221c. Specifically, the rounded corners 221c at the connection between the clamping arm 21 and the first clamping bar 221, and the first clamping bar 221 and the second clamping bar 222, avoid stress concentration caused by sharp corners or acute angles, help to distribute the load, and improve the structural strength and fatigue life of the entire clamping assembly 2 during repeated clamping / releasing.
[0061] One specific implementation of the first clip 221 and the second clip 222 is as follows: the end faces of the first clip 221 and the second clip 222 are square. Specifically, the first clip 221 and the second clip 222 are formed by cutting the sheet-like V-shaped clamping arm 21 to form a square cross section, and then bending the first clip 221 and the second clip 222. The processing technology is simple, the structure is highly integrated, and additional processes such as welding and splicing are reduced, thereby reducing processing costs.
[0062] Another specific implementation of the first clip 221 and the second clip 222 is as follows: the end faces of the first clip 221 and the second clip 222 are circular (not shown). The circular cross-section of the first clip 221 and the second clip 222 forms point contact with the surface of the cylindrical small button-like workpiece 01, further reducing the contact area, effectively increasing the processable area of the workpiece during the anodizing process, helping to form a more uniform anodizing current path, and improving the consistency of oxide layer thickness and surface quality.
[0063] In this embodiment, the surfaces of the first clip 221 and the second clip 222 opposite to each other are provided with small protrusions (not shown) to increase friction and enhance clamping stability.
[0064] Among them, the upper and lower rows of clamping components 2 of the hanger 1 are staggered. Specifically, the staggered structure can prevent the upper row of workpieces from blocking the current or electrolyte flow path of the lower row of workpieces during the anodizing process, reduce the shadow effect and local current density changes, and improve the consistency of the oxide layer.
[0065] As a preferred embodiment of the above, the clamping component 2 and the hanger 1 are detachably connected, which can be quickly replaced when the clamp is worn, fails, or needs to be replaced, without having to replace the entire hanger 1, thus saving maintenance costs and time. Specifically, the clamping component 2 and the hanger 1 can be connected by snap-fit or by screw, both of which are within the protection scope of this application.
[0066] In this embodiment, at least one lifting structure 11 is provided on the hanger 1 to lift the hanger 1 as a whole. The entire set of hanging fixtures can be quickly lifted into or out of the electrolytic cell by means of hooks, robotic arms and other equipment, which significantly improves handling efficiency and operation speed and is suitable for assembly line operation requirements.
[0067] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
