Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to an insulated double-headed clamp. Background Technology

[0002] Anodizing is a surface treatment process for aluminum materials. It typically involves exposing the aluminum material to an electrolyte solution and applying an electric current. The electrolytic principle causes the aluminum to react with oxygen, forming a dense oxide film. This oxide film possesses corrosion resistance, hardness, and aesthetic appeal, making it important in many applications.

[0003] The electrolyte used in anodizing is usually sulfuric acid, a strong acid. To ensure operator safety, there are high requirements for the stable clamping of aluminum materials. For example, a sheet metal clamp with announcement number CN220703823U includes: a clamping assembly comprising an elastic element, a clamping block, and a connecting block; one end of the elastic element is connected to the clamping block, and the other end is connected to the connecting block; the clamping block and the connecting block are hinged; and a mounting base that cooperates with the clamping assembly to clamp the workpiece to be processed, with the connecting block mounted on the mounting base. While this clamp solves the problems of easy detachment and unstable clamping in traditional clamps during the anodizing process, in actual use, there are often situations where operators experience electric leakage or electric shock during manual operation, which can seriously endanger the operator's personal safety and significantly reduce production efficiency. Utility Model Content

[0004] Therefore, in order to solve the problem of easy leakage of current during the operation of the clamp, this utility model provides an insulated double-headed clamp, the specific technical solution of which is as follows:

[0005] An insulating double-headed clamp includes a base and a clamping mechanism. An insulating structure is mounted on the base, and insulating flat pads and insulating stepped pads are arranged sequentially on the insulating structure, forming an installation gap between the insulating flat pads and the insulating stepped pads. The clamping mechanism includes a clamping component and a mounting seat that engages with the installation gap. The clamping component is rotatably mounted on the mounting seat, and the clamping component is provided with insulating teeth for engaging with the base to clamp aluminum materials.

[0006] The aforementioned insulated double-headed clamp, by incorporating an insulating structure with an installation gap, facilitates the snap-fit ​​installation of the mounting base while simultaneously insulating it, preventing leakage and electric shock during manual operation and resolving the issue of leakage during clamp operation. The clamping components, working in conjunction with the base, effectively hold the aluminum material. Furthermore, the insulated toothed plates enable rapid positioning and clamping of the aluminum material, reducing auxiliary time and thus improving production efficiency.

[0007] Furthermore, the base platform includes a clamping plate and a base plate. The base plate is mounted on top of the clamping plate and is fixed to the clamping plate by screws. One end of the clamping plate extends out of the base plate and forms a clamping step. The insulating toothed plate cooperates with the clamping step to clamp the aluminum material.

[0008] Furthermore, the insulating structure includes a first positioning bolt and a second positioning bolt. The first positioning bolt is threaded onto one end of the base plate and passes through the base plate and the clamping plate in sequence.

[0009] Furthermore, the second positioning bolt is threaded onto the other end of the base plate, and the bottom of the second positioning bolt extends out of the base plate and is threaded onto a balance nut, with the bottom of the clamping plate flush with the bottom of the balance nut.

[0010] Furthermore, the first positioning bolt is fitted with the insulating flat washer and the insulating stepped washer in sequence, and the second positioning bolt is also fitted with the insulating flat washer and the insulating stepped washer in sequence, with an installation gap formed on both the first positioning bolt and the second positioning bolt.

[0011] Furthermore, the mounting base has snap-fit ​​holes at both ends, which snap into the mounting gap.

[0012] Furthermore, the clamping assembly includes a pull rod, an elastic element, and a first rotating shaft rotatably mounted on one end of the mounting base. The pull rod is sleeved on the first rotating shaft by a stud. One end of the elastic element is connected to the pull rod, and the other end of the elastic element is connected to the other end of the mounting base.

[0013] Furthermore, the clamping assembly also includes a connecting piece and a second rotating shaft located below the first rotating shaft. The connecting piece is connected between the pull rod and the insulating toothed plate. The second rotating shaft is rotatably mounted on the mounting base, and the insulating toothed plate is sleeved on the second rotating shaft by a stud.

[0014] Furthermore, the clamping assembly also includes a first spacer and a second spacer, the first spacer being sleeved on the first rotating shaft and located between the pull rod and the mounting base, and the second spacer being sleeved on the second rotating shaft and located between the insulating toothed plate and the mounting base.

[0015] Furthermore, the elastic element is a tension spring, and rubber sleeves are provided at the connection between the elastic element and the pull rod, as well as at the connection between the elastic element and the mounting base. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0025] like Figures 1-3As shown, an insulating double-headed clamp in one embodiment of the present invention includes a base 1 and a clamping mechanism; an insulating structure 2 is installed on the base 1, and an insulating flat pad 3 and an insulating stepped pad 4 are arranged sequentially on the insulating structure 2, forming an installation gap between the insulating flat pad 3 and the insulating stepped pad 4; the clamping mechanism includes a clamping component 5 and a mounting seat 6 that is engaged in the installation gap, the clamping component 5 is rotatably mounted on the mounting seat 6, and the clamping component 5 is provided with insulating toothed plates 51 for cooperating with the base 1 to clamp aluminum materials.

[0026] The aforementioned insulated double-headed clamp, by providing an insulating structure 2 with an installation gap, facilitates the snap-fit ​​installation of the mounting base 6 while also insulating the mounting base 6, preventing leakage and electric shock during manual operation and solving the problem of leakage during clamp operation; by providing a clamping component 5, which works with the base 1 to achieve the clamping effect on the aluminum material; and by providing an insulating toothed plate 51, the aluminum material can be quickly positioned and clamped, reducing auxiliary time and thus improving production efficiency.

[0027] Specifically, the insulating toothed plate 51 is made of ceramic material. Ceramic material has excellent mechanical strength and wear resistance, which can maintain stable performance during long-term use, reduce processing errors caused by wear, and has good corrosion resistance, which can be used for a long time in corrosive environments such as acids and alkalis, thus extending its service life.

[0028] like Figures 1-3 As shown, in one embodiment, the base 1 includes a clamping plate 11 and a base plate 12. The base plate 12 is mounted on top of the clamping plate 11. The base plate 12 and the clamping plate 11 are fixed together by screws 13. One end of the clamping plate 11 extends out of the base plate 12 and forms a clamping step. The insulating toothed plate 51 cooperates with the clamping step to clamp the aluminum material.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, the insulating structure 2 includes a first positioning bolt 21 and a second positioning bolt 22. The first positioning bolt 21 is threaded onto one end of the base plate 12 and passes through the base plate 12 and the clamping plate 11 in sequence. By providing the first positioning bolt 21, the base plate 12 and the clamping plate 11 are connected in combination, which has high load-bearing capacity and fatigue resistance, can maintain the stability and reliability of the connection during long-term use, and is easy to disassemble and maintain.

[0030] like Figure 2As shown, in one embodiment, the second positioning bolt 22 is threadedly fixed to the other end of the base plate 12, and the bottom of the second positioning bolt 22 extends out of the base plate 12 and is threadedly connected to a balance nut 221. The bottom of the clamping plate 11 is flush with the bottom of the balance nut 221. By providing the balance nut 221, the other end of the base plate 12 is made flush with the clamping plate 11, preventing the base platform 1 from tilting during operation and affecting the clamping effect.

[0031] like Figure 2 As shown, in one embodiment, an insulating flat washer 3 and an insulating stepped washer 4 are sequentially fitted on the first positioning bolt 21, and an insulating flat washer 3 and an insulating stepped washer 4 are also sequentially fitted on the second positioning bolt 22. An installation gap is formed on both the first positioning bolt 21 and the second positioning bolt 22.

[0032] In one embodiment, the mounting base 6 has snap-fit ​​holes at both ends, which snap into the mounting gap.

[0033] like Figures 1-3 As shown, in one embodiment, the clamping assembly 5 includes a pull rod 52, an elastic element 53, and a first rotating shaft 54 ​​rotatably mounted on one end of the mounting base 6. The pull rod 52 is sleeved on the first rotating shaft 54 ​​by a stud. One end of the elastic element 53 is connected to the pull rod 52, and the other end of the elastic element 53 is connected to the other end of the mounting base 6. Thus, by providing the pull rod 52, the operator can easily control the clamping state of the insulating toothed plate 51 on the clamping plate 11. By providing the elastic element 53, when no external force is applied, the rings of the elastic element 53 are in close contact, generating an initial tensile force, which helps control the stiffness and improves the stability of the aluminum material during clamping.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the clamping assembly 5 further includes a connecting piece 55 and a second rotating shaft 56 located below the first rotating shaft 54. The connecting piece 55 connects the pull rod 52 and the insulating toothed plate 51. The second rotating shaft 56 is rotatably mounted on the mounting base 6, and the insulating toothed plate 51 is sleeved on the second rotating shaft 56 by a stud. Compared with traditional clamps, the insulating toothed plate 51 forms a shorter lever arm, resulting in a smaller torque on the insulating toothed plate 51 when the weight of the aluminum material exerts an upward lever force on the insulating toothed plate 51 as a fulcrum during clamping. This makes the aluminum material less prone to loosening and achieves a stable clamping effect.

[0035] like Figure 1 and Figure 3As shown, in one embodiment, the clamping assembly 5 further includes a first spacer 57 and a second spacer 58. The first spacer 57 is sleeved on the first rotating shaft 54 ​​and is located between the pull rod 52 and the mounting base 6. The second spacer 58 is sleeved on the second rotating shaft 56 and is located between the insulating toothed plate 51 and the mounting base 6. By providing the first spacer 57 and the second spacer 58, the pull rod 52 and the insulating toothed plate 51 are protected, preventing friction and collision between them and the mounting base 6 that could lead to wear, thus extending their service life.

[0036] Furthermore, there are multiple clamping components 5 and multiple mounting bases 6, with the multiple clamping components 5 arranged at intervals on the mounting bases 6. By providing multiple clamping components 5, the insulated double-headed clamp provides support to the aluminum material in different vertical directions on the plane of the aluminum material during clamping. This avoids the problem of the aluminum material easily rotating and swinging around the insulated double-headed clamp as an axis, which can cause loosening when there is only one clamping component 5. This increases the balance and stability of the insulated double-headed clamp.

[0037] Preferably, the number of clamping components 5 and the number of mounting bases 6 are both two.

[0038] In one embodiment, the elastic element 53 is a tension spring, and rubber sleeves 59 are provided at the connection between the elastic element 53 and the pull rod 52, as well as at the connection between the elastic element 53 and the mounting base 6. The rubber sleeves 59 have a certain insulating function.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
