Description

Technical Field

[0001] This utility model relates to the field of bar feeding technology, specifically to a clamping conductive device and a clamping body reset mechanism. Background Technology

[0002] Electroplating rods are rods with a metal element layer of 20-30μm thickness formed on the surface of hard optical shafts through electroplating. They are suitable for use in automated industries and with linear bearings. During electroplating, the plating rods are generally clamped by conductive clamps.

[0003] In related technologies, conductive clamps typically use alligator clips or screws to fix the rod to the conductive clamp. This method is prone to poor contact during use, affecting the conductivity. While a wraparound clamp conductive mechanism can avoid poor contact, it requires high machining precision and is more expensive, making it unsuitable for large-scale production applications. Utility Model Content

[0004] In view of this, the present invention provides a clamping conductive device to solve the problems of complex structure, low clamping stability and high cost of clamping conductive devices.

[0005] On the one hand, this utility model provides a clamping conductive device, including:

[0006] The mounting base is provided with at least two first slide rails;

[0007] A pair of movable seats are disposed opposite to each other on the mounting base. Each movable seat has a first slider on one side that corresponds to the first slide rail, so that the movable seat reciprocates along the first slide rail.

[0008] A pair of clamping components are respectively disposed on the other side of the pair of movable seats;

[0009] The clamping assembly includes a clamping body, which is fixedly connected to the movable seat;

[0010] A pair of movable supports are arranged vertically along the clamping body and are rotatably mounted on the clamping body;

[0011] Each of the pair of movable supports is connected to a clamping plate support, and the clamping plate support is connected to a clamping plate.

[0012] Beneficial effects: By setting at least two first slide rails on the mounting base, a pair of movable seats are positioned opposite each other on the mounting base. The cooperation between the first slider on the movable seat and the first slide rail on the mounting base allows the movable seat to reciprocate along the first slide rail, thereby adjusting the distance between the two clamping components to clamp and release the bar. A pair of movable supports are provided vertically in the clamping components. These movable supports are rotatably connected to the clamping body, and clamping plate supports and clamping plates are sequentially connected to the movable supports. This allows the clamping plates to have an adjustable angle when clamping the bar, making it suitable for clamping bars of different diameters. Since each clamping assembly has two movable supports, each clamping assembly includes two clamping plates arranged vertically along the clamping body. When the conductive clamping device clamps the rod, the four clamping plates on the two clamping assemblies abut against the rod, giving the rod four clamping points. This ensures the stability of the contact surface between the clamping plates and the rod, and allows the rod to automatically center itself. Furthermore, it increases the conductive contact surface between the clamping plates and the rod, ensuring a greater current carrying capacity and allowing for more uniform current transmission to the rod. In addition, the conductive clamping device provided by this invention has a simple structure, high clamping stability, and low manufacturing cost.

[0013] In one alternative embodiment, a centering assembly is further included, the centering assembly comprising a support rod and a movable rod, the support rod being rotatably mounted on the mounting base, and one end of the movable rod being rotatably connected to the support rod and the other end being rotatably connected to the movable seat.

[0014] In one alternative embodiment, the clamping assembly further includes a flexible braided strip disposed on the clamping plate.

[0015] In one alternative embodiment, the clamp has a V-shaped groove on the end face of the side closest to the flexible braided strip.

[0016] In one alternative embodiment, the flexible braided tape is a metal flexible braided tape.

[0017] In one alternative embodiment, the clamping assembly further includes a plurality of elastic elements disposed between the clamping plate bracket and the movable bracket.

[0018] In one alternative embodiment, a clamping cylinder assembly is further included, disposed on the mounting base and connected to the clamping body, for providing clamping force to the clamping assembly.

[0019] On the other hand, this utility model also provides a clamp reset mechanism, comprising:

[0020] Linear displacement mechanism;

[0021] At least one clamping conductive device as described above, the clamping conductive device being disposed on the linear displacement mechanism and reciprocating along the linear displacement mechanism.

[0022] In one optional embodiment, the linear displacement mechanism includes at least two second slide rails and a second slider corresponding to each of the second slide rails. The second slider is disposed on the mounting base, causing the mounting base to reciprocate along the second slide rails.

[0023] In one alternative embodiment, at least one drive cylinder is further included, which is fixedly connected to the mounting base, for providing reset power to the clamping conductive device. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] According to embodiments of the present invention, such as Figures 2 to 5 As shown, a conductive clamping device 10 is provided, comprising: a mounting base 100, on which at least two first slide rails 130 are provided; a pair of movable seats 110, which are disposed opposite to each other on the mounting base 100, and a first slider 120 corresponding to the first slide rails 130 is provided on one side of each movable seat 110, so that the movable seat 110 reciprocates along the first slide rails 130; a pair of clamping assemblies, which are disposed corresponding to each other on the other side of the pair of movable seats 110; the clamping assemblies include a clamping body 111, which is fixedly connected to the movable seat 110; a pair of movable brackets 112, which are disposed vertically along the clamping body 111 and rotatably disposed on the clamping body 111; and clamping plate brackets 113 are respectively connected to the pair of movable brackets 112, and clamping plates 114 are connected to the clamping plate brackets 113.

[0034] In this embodiment, the mounting base 100 is provided with two parallel first slide rails 130, which extend along the length of the mounting base 100. The mounting base 100 is made of metal and has sufficient strength and rigidity to stably support the entire structure of the clamping conductive device 10. A pair of movable seats 110 are arranged opposite each other on the mounting base 100. Each movable seat 110 has two first sliders 120 at its bottom. The two first sliders 120 slide in cooperation with the two first slide rails 130, so that the movable seat 110 can move smoothly back and forth along the direction of the first slide rails 130, thereby adjusting the distance between the two clamping components to clamp and release the rod.

[0035] Clamping assemblies are provided on the other side of each pair of movable seats 110. Each clamping assembly includes a clamping body 111, which is fixedly connected to the movable seat 110. The clamping body 111 and the movable seat 110 are fixedly connected by bolts to ensure a firm and reliable connection. Each clamping assembly also includes a pair of movable brackets 112, which are arranged vertically along the clamping body 111 and rotatably mounted on the clamping body 111. The movable brackets 112 are connected to the clamping body 111 via a pivot and can rotate around the pivot at a certain angle to accommodate clamping bars of different diameters. Clamping plate brackets 113 are respectively connected to the pair of movable brackets 112, and clamping plates 114 are connected to the clamping plate brackets 113. The clamping plate brackets 113 and the movable brackets 112 are connected by bolts, and the connection position can be adjusted as needed. The clamping plates 114 are fixed to the clamping plate brackets 113 and are used to contact and clamp the bars.

[0036] Since each clamping assembly is equipped with two movable supports 112, each clamping assembly includes two clamping plates 114 arranged vertically along the clamping body 111. When the clamping conductive device 10 clamps the rod, the four clamping plates 114 on the two clamping assemblies abut against and clamp the rod, giving the rod four clamping points. This ensures the stability of the contact surface between the clamping plates 114 and the rod, and allows the rod to automatically center itself. Furthermore, it increases the conductive contact surface between the clamping plates 114 and the rod, ensuring a greater current carrying capacity and allowing the current to be transmitted to the rod more evenly. In addition, the clamping conductive device 10 provided by this invention has a simple structure, high clamping stability, and low manufacturing cost.

[0037] In one embodiment, an alignment component is also included, comprising a support rod 131 and a movable rod 132. The support rod 131 is rotatably mounted on the mounting base 100, and one end of the movable rod 132 is rotatably connected to the support rod 131, and the other end is rotatably connected to the movable seat 110.

[0038] In this embodiment, the support rod 131 is rotatably mounted on the mounting base 100. A through hole is provided in the middle of the support rod 131. One end of a rotating shaft is disposed within the through hole and hinged to the support rod 131, while the other end is connected to the mounting base 100, allowing the support rod 131 to rotate around the rotating shaft. Two movable rods 132 are provided. One end of one movable rod 132 is rotatably connected to the support rod 131, and the other end is rotatably connected to one of the movable seats 110. One end of the other movable rod 132 is rotatably connected to the other end of the support rod 131, and the other end is rotatably connected to the other movable seat 110. The centering assembly ensures synchronous movement of the pair of movable seats 110, guaranteeing the symmetry and stability of the clamping. Furthermore, even if the clamping cylinder assembly 117 of one clamping component malfunctions, the other clamping cylinder assembly 117 can still drive the two movable seats 110 to move bilaterally. Further, the centering assembly also has a centering compensation function to ensure that the two clamping plates 114 are automatically centered, suitable for electroplating rods of different diameters.

[0039] In one embodiment, the clamping assembly further includes a flexible braided strip 115 disposed on the clamping plate 114. Further, the flexible braided strip 115 is a metal flexible braided strip 115.

[0040] In this embodiment, the flexible braided tape 115 is a metal flexible braided tape 115, which can be woven from multiple fine metal wires and has good flexibility, wear resistance, and conductivity. The flexible braided tape 115 covers the surface of the clamping plate 114 and directly contacts the clamped rod. The flexible braided tape 115 deforms under compression, thereby increasing the contact area between the rod and the flexible braided tape 115, thus avoiding poor contact between the flexible braided tape 115 and the rod, reducing electrical shock, preventing damage to the product surface and thus avoiding damage to the plating, and improving the connection stability between the flexible braided tape 115 and the rod. Moreover, the multiple clamping plates 114 and the flexible braided tape 115 are all clamped onto the rod, which can enhance the current carrying capacity of the clamping plate 114 and make the current transmission more uniform.

[0041] In other possible implementations, the clamping assembly also includes a connector 116, which is mounted on the clamping body 111. The two ends of the connector 116 are respectively connected to the two clamping plates 114 of the clamping assembly, which can further enhance the conductivity of the clamping plates 114.

[0042] In one embodiment, the clamping plate 114 has a V-shaped groove on one end face near the flexible braided strip 115.

[0043] In this embodiment, by providing a V-shaped groove on the end face of the clamping plate 114 near the flexible braided strip 115, the clamping plate 114 can better adapt to the clamping of round or polygonal rods, increasing the contact area with the rods and improving clamping stability. Moreover, when the clamping plate 114 clamps the rods, the V-shaped groove can also play a certain centering role, so as to enhance the stability of the rod clamping.

[0044] In one embodiment, the clamping assembly further includes a plurality of elastic elements disposed between the clamping plate bracket 113 and the movable bracket 112.

[0045] In this embodiment, a compression spring is provided between each clamping plate bracket 113 and its corresponding movable bracket 112 as an elastic element. The provision of the elastic element enables the clamping plate 114 to have a certain elastic buffering effect when clamping the workpiece, which can adapt to workpieces of different hardness and shape, while avoiding damage to the workpiece due to excessive clamping force.

[0046] In one embodiment, a clamping cylinder assembly 117 is also included, which is disposed on the mounting base 100 and connected to the clamping body 111, for providing clamping force to the clamping assembly.

[0047] In this embodiment, the clamping cylinder assembly 117 may include a cylinder and a piston. The piston is disposed in the cavity of the cylinder. The cylinder is mounted on the mounting base 100 and the piston is connected to the clamping body 111. The cylinder provides driving force to drive the piston to move, and the piston controls the clamping body 111 to move reciprocally along the first guide rail.

[0048] In other possible implementations, a motor and transmission mechanism can be used to provide clamping force to the clamping assembly. The motor is fixed to the mounting base 100, and the transmission mechanism transmits power to the clamping body 111, controlling the clamping body 111 to reciprocate along the first guide rail. The motor is a servo motor, which can control the magnitude of the clamping force. The transmission mechanism includes gears and racks, converting the rotational motion of the motor into the linear motion of the clamping assembly.

[0049] During use, the conductive clamping device 10 is first installed in a suitable position. Then, the clamping cylinder assembly 117 controls a pair of movable seats 110 to move towards or away from each other along the first slide rail 130, changing the distance between the pair of clamping assemblies. When a workpiece needs to be clamped, the pair of movable seats 110 are controlled to move towards each other, causing the clamping plate 114 to contact the surface of the bar. The flexible braided strap 115 increases the contact area with the bar, achieving a stable clamping of the workpiece. When the workpiece needs to be released, the pair of movable seats 110 are controlled to move away from each other, causing the clamping plate 114 to move away from the workpiece, completing the release action.

[0050] On the other hand, such as Figure 1As shown, this utility model also provides a clamping resetting mechanism, including: a linear displacement mechanism; at least one clamping conductive device 10, the clamping conductive device 10 being disposed on the linear displacement mechanism and reciprocating along the linear displacement mechanism. Further, the linear displacement mechanism includes at least two second slide rails 20 and second sliders 200 corresponding to each of the second slide rails 20, the second sliders 200 being disposed on the mounting base 100, causing the mounting base 100 to reciprocate along the second slide rails 20.

[0051] In this embodiment, the direct displacement structure is mounted on the surface to be installed, which can be the ground or a machine platform. The linear displacement mechanism includes two parallel second slide rails 20, which are fixed to the surface to be installed and extend along the feeding direction. Simultaneously, two second sliders 200 are provided at the bottom of the mounting base 100, and the two second sliders 200 respectively slide in engagement with the two second slide rails 20, thereby enabling the entire clamping conductive device 10 to reciprocate smoothly along the direction of the second slide rails 20.

[0052] In one embodiment, at least one drive cylinder 30 is also included, which is fixedly connected to the mounting base 100, for providing reset power for clamping the conductive device 10.

[0053] In this embodiment, the drive cylinder 30 and the clamping conductive device 10 are arranged in a one-to-one correspondence. The cylinder body of the drive cylinder 30 is fixed on the surface to be installed, and the piston rod is connected to the mounting base 100. By controlling the extension and retraction of the drive cylinder 30, the clamping conductive device 10 can be driven to reciprocate on the second slide rail 20 to realize the clamping body reset function.

[0054] During use, two clamping conductive devices 10 can be set up. The clamping component of one of the clamping conductive devices 10 clamps the rod. Then, the drive cylinder 30 connected to the clamping conductive device 10 pushes the clamping conductive device 10 and the rod to move along the second slide rail 20. When the drive cylinder 30 reaches its maximum movement range, the clamping component of the clamping conductive device 10 releases the rod and controls the clamping conductive device 10 to return to its initial position, ready for the next feeding operation. At the same time, the clamping component of the other clamping conductive device 10 clamps the rod and controls the drive cylinder 30 connected to the clamping conductive device 10 to retract. When the drive cylinder 30 retracts to its minimum movement range, the clamping component is controlled to release the rod, and the other clamping device is controlled to clamp the rod again. This reciprocating alternation achieves the clamping and synchronous movement of the rod.
