Description

Technical Field

[0001] This utility model relates to a basket clamp, and more particularly to a basket clamp with a tensioning device. Background Technology

[0002] Electroplating equipment using hanging baskets is generally used for electroless processes. The hanging basket is used to fix the electroplated parts, usually by clamping them directly. In this operating condition, the temperature of the chemical solution is usually high because activation is achieved at high temperatures. As a result, products exposed from a low-temperature room temperature environment to a high-temperature chemical solution will become uneven and develop depressions. Therefore, only thicker products can be produced because thicker products have a larger heat capacity, a gentler temperature gradient, and higher rigidity, which can resist thermal stress deformation and is less prone to deformation.

[0003] However, in the actual electroplating process, there is a large demand for thin sheet products. Since thin sheet products do not have the aforementioned characteristics of thicker products, they are prone to deformation during the electroplating process, which leads to the inability to guarantee the flatness of the products, resulting in a low yield rate of electroplated parts and failing to meet the current electroplating requirements. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a basket clamp with a tensioning device, which can ensure that thin plate products have good flatness and no deformation during electroplating, and that the yield of electroplated products is high.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a basket-type clamp with a tensioning device, comprising:

[0006] support;

[0007] A pressing component, which is movably protrudes from the bracket;

[0008] A clamping assembly is disposed at the front end of the pressing assembly for clamping or releasing the product when the pressing assembly moves within the bracket;

[0009] The tensioning part is disposed between the clamp assembly and the pressing assembly;

[0010] A telescopic assembly, one end of which is rotatably connected to the clamp assembly, and the other end of which is connected to the bracket via an elastic component;

[0011] When the pressing component moves forward, the tensioning part and the elastic component are compressed, and the clamping assembly is in an open state; when the pressing component retracts, the clamping assembly is in a clamping state and the tensioning part and the elastic component provide clamping tension for the clamping assembly.

[0012] Furthermore, the bracket is U-shaped, and the pressing component, tensioning part, telescopic component, elastic component and clamping component are all disposed on one side of the U-shape of the bracket.

[0013] Furthermore, the pressing assembly includes an end cap and a pressing rod; the end cap is tightly attached to one side end face of the bracket; the pressing rod is connected to the end cap, and extends out of the bracket and is connected to the clamping assembly, the front end of the pressing rod has an abutment portion that contacts the clamping assembly, and a guide screw is provided in the vertical direction of the abutment portion.

[0014] Furthermore, the clamp assembly includes:

[0015] Mounting base, the pressure rod protrudes from the mounting base;

[0016] A base is provided on one side of the mounting base. A U-shaped groove is provided at the front end of the base. A clamping part extending from the base is provided along one side of the U-shaped groove, and a fixing screw is provided on the other side to pass through and fix the base. Two parallel waist holes are also provided on the base opposite to the U-shaped groove, so that the guide screw can move laterally along the two waist holes.

[0017] The clamping block is rotatably mounted on the fixing screw, and a torsion spring sleeved on the fixing screw is provided between the upper surface of the clamping block and the base.

[0018] A transmission screw is disposed through the base and located between the guide screw and the fixing screw; the transmission screw is provided with a rotating block, one end of which abuts against the contact part, and the other end is rotatably connected to the clamping block;

[0019] When the pressure rod moves forward, it drives the contact part to move forward until the contact part contacts the rotating block and drives the rotating block to rotate clockwise. The rotating block simultaneously drives the clamping block to rotate counterclockwise, and the torsion spring is compressed. At this time, the clamping block and the clamping part are in a loose state.

[0020] When the pressure rod moves backward, it causes the contact part to move backward, and the torsion spring returns to its elastic force, thereby causing the clamping block to rotate clockwise and clamp the product with the clamping part.

[0021] Furthermore, the telescopic assembly includes telescopic frames disposed on both sides of the mounting base, and one end of each of the two telescopic frames is rotatably connected to the mounting base, and the other end is connected to an elastic component via a transmission shaft, wherein the elastic component is connected to the bracket.

[0022] Furthermore, the tensioning part includes two tension springs, which are respectively disposed at the upper and lower ends of the pressure rod, and are respectively connected to the end cap and the mounting base.

[0023] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0024] This utility model relates to a basket-type clamp with a tensioning device. By linking the tensioning part, the elastic component, and the clamp assembly together, when the clamp assembly is released, the pressure bar moves forward, first compressed by the tensioning part, and then the clamp assembly is released. When it is necessary to clamp the product, the pressure bar retracts, the clamp assembly clamps the product, and the tensioning part and the elastic component provide tension to the clamp blocks, thereby providing uniform mechanical tension to stretch the thin plate, maintain its flatness, and avoid uneven plating thickness due to deformation. The product has a good electroplating effect, meeting the needs of enterprises during electroplating. Attached Figure Description

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] This utility model provides a basket-type clamp with a tensioning device to solve the problem that when thin sheet products are electroplated using clamps in the prior art, the shape becomes uneven and dents appear, which makes the thin sheet products prone to deformation after electroplating.

[0036] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figures 1 to 3 A basket clamp with a tensioning device according to an embodiment of this application includes a bracket 1, a pressing component 2, a clamping component 3, a telescopic component 4, and a tensioning part 5; the pressing component 2 movably extends out of the bracket 1; the clamping component 3 is disposed at the front end of the pressing component 2, and is used to clamp or release the product when the pressing component 2 moves within the bracket 1; the tensioning part 5 is disposed between the clamping component 3 and the pressing component 2; one end of the telescopic component 4 is rotatably connected to the clamping component 3, and the other end is connected to the bracket 1 through an elastic member 6.

[0037] This utility model discloses a basket-type clamp with a tensioning device. When the pressing component moves forward, it first compresses the tensioning part and the elastic component, at which point the clamp assembly is in a loose state. When the pressing component 2 retracts, the clamp assembly 3 is in a clamping state and tension is provided to the clamp assembly 3 through the tensioning part 5 and the elastic component 6. This increases the tension when the clamp assembly 3 clamps the thin plate product, thereby stretching the thin plate and making the product flat and free of dents when clamped, resulting in a high yield rate of electroplated products.

[0038] For further details, please refer to [link / reference]. Figure 6The bracket 1 is in the shape of a sideways U, and the pressing component 2, tensioning part 5, telescopic component 4 and clamping component 3 are all located on one side of the U-shape of the bracket 1.

[0039] For further details, please refer to [link / reference]. Figures 1 to 3 , Figure 6 and Figure 7 The pressing assembly 2 includes an end cap 20 and a pressing rod 21; the end cap 20 is tightly attached to one side end face of the bracket 1; the pressing rod 21 is connected to the end cap 20, and extends out of the bracket 1 and is connected to the clamp assembly 3; the front end of the pressing rod 21 has an abutment portion 22 that contacts the clamp assembly 3, and the abutment portion 22 is arc-shaped; a guide screw 23 is provided in the vertical direction of the abutment portion 22.

[0040] Furthermore, the clamp assembly 3 includes a mounting base 39, a base 30, a clamping part 32, a fixing screw 33, a clamping block 35, and a transmission screw 36. The base 30 is disposed on one side of the mounting base 39, and the pressure rod 21 extends from the mounting base 39 to the base 30. The base 30 has a U-shaped cross-section, and a U-shaped groove 31 is opened at the front end of the base 30. A clamping part 32 extending from the base 30 is disposed along one side of the U-shaped groove 31. A fixing screw 33 is disposed on the other side of the U-shaped groove 31 and is fixed to the base 30. The clamping block 35 is rotatably disposed on the fixing screw, and a torsion spring sleeved on the fixing screw 33 is also disposed between the upper surface of the clamping block 35 and the base. The clamping block 35 and the clamping part 32 constitute a clamping assembly for clamping the product.

[0041] The base 30 is provided with two parallel waist holes 34 on the opposite side of the U-shaped groove 31, and the guide screw 23 is located in the two waist holes 34. When the pressure rod 21 moves, the guide screw 23 moves along the two waist holes 34. The guide screw plays the role of guiding the pressure rod 21 to ensure that the direction of movement does not deviate.

[0042] The transmission screw 36 is disposed through the base 30 and is located between the guide screw 23 and the fixing screw 44; the transmission screw 36 is provided with a rotating block 37, one end of the rotating block 37 abuts against the contact part 22, and the other end is rotatably connected to the clamp block 35.

[0043] During operation, when the pressure rod 21 moves forward, it drives the contact part 22 to move forward along the direction of the waist hole until the contact part 22 contacts the rotating block 37. Then, when it continues to move forward, it pushes the contact part 22 to make contact with the rotating block 37, which drives the rotating block 37 to rotate clockwise around the transmission screw 36. The clockwise rotation of the rotating block 37 drives the clamping block 35 to rotate counterclockwise around the fixing screw 33. At this time, the torsion spring 38 is compressed, and the clamping block 35 and the clamping part 32 are in a loose state and will not clamp the product.

[0044] When the pressure rod 21 moves backward, it causes the contact part 22 to move backward, and the torsion spring 38 restores its elasticity, thereby causing the clamp block 35 to rotate clockwise and cooperate with the clamp part 32 to clamp the product.

[0045] For further details, please refer to [link / reference]. Figure 3 and Figure 4 The telescopic assembly 4 includes telescopic frames 41 disposed on both sides of the mounting base 39. One end of each telescopic frame 41 is rotatably connected to the mounting base 39, and the other end is connected to an elastic member 6 via a transmission shaft 42. The elastic member 6 is connected to the bracket 1. Thus, one end of the telescopic assembly is telescopically connected to the bracket 1 via the elastic member 6, and the other end is rotatably connected to the mounting base 39. When the pressure rod 21 moves forward, it causes the telescopic frames 41 to retract, and the elastic member 6 is simultaneously compressed.

[0046] In addition, the tensioning part 5 includes two tension springs 50, which are respectively disposed at the upper and lower ends of the pressure rod 21, and the two ends of the tension springs 50 are respectively connected to the end cover 20 and the mounting base 39.

[0047] In this embodiment, the elastic component 6 is a spring.

[0048] When the pressure rod 21 moves forward, the upper and lower tension springs 50 are compressed first, and simultaneously drive the telescopic frame 41 to retract. After the telescopic frame 41 retracts, it simultaneously drives the elastic component 6 located between the telescopic frame 41 and the support 1 to be compressed. Thus, when the pressure rod 21 moves backward, the tension springs 50 and the elastic component 6 provide tension to the clamp assembly.

[0049] In addition, the elastic restoring force provided by the tension spring 50 and the elastic component 6 is weaker than the force of the torsion spring that closes the clamp, which ensures that the tension spring 50 provides tension to the torsion spring to achieve the tensioning effect on the product.

[0050] based on Figures 1 to 7 The actual work process is as follows:

[0051] When the product is released, the end cap 20 is pressed down. The end cap 20 drives the pressure rod 21 to move forward through the bracket 1. At this time, the two tension springs 50 are compressed first. After the tension springs are compressed, the telescopic frame moves forward. After the telescopic frame moves forward, the elastic component is also compressed. Then the pressure rod continues to move forward. The front end of the pressure rod 21 moves forward along the waist hole 34 until the contact part 22 contacts the rotating block. After the rotating block 37 rotates, it drives the clamping block 35 to rotate counterclockwise. The torsion spring 38 is compressed. At this time, the clamping block and the clamping part are in an open state and cannot clamp the product.

[0052] When clamping the product, the sequence of action is the reverse of the above. Pulling the end cap 20 outward causes the end cap 20 to move the pressure rod 21 back within the bracket 1. After the torsion spring 38 regains its elasticity, it causes the clamping block 35 to rotate clockwise. The clamping block and clamping part close together, clamping the thin sheet product. Simultaneously, the presence of the tension spring and elastic component, and because the elasticity of the tension spring and elastic component is weaker than that of the torsion spring, allows the tension spring and elastic component to apply tension to the clamping block, which is then transmitted to the product. This ensures the product is in a stretched clamping state, maintaining flatness and preventing indentation, resulting in a high product yield.

[0053] This invention links the tensioning part, the elastic component, and the clamping assembly together. When the clamping assembly is released, the pressure rod moves forward, first compressing the tensioning part and the elastic component, and then causing the clamping assembly to release. When it is necessary to clamp the product, the pressure rod retracts, the clamping assembly clamps the product, and the tensioning part and the elastic component provide tension to the clamping block, thereby providing uniform mechanical tension to stretch the thin plate, maintain its flatness, and avoid uneven plating thickness due to deformation. The product has a good electroplating effect and meets the needs of use.

[0054] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
