Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping device for forging automotive camshafts. Background Technology

[0002] Automotive camshaft forging is a manufacturing process that involves heating steel at high temperatures and applying strong pressure to shape it. It is mainly used to produce critical camshaft parts in engines.

[0003] In the traditional automotive camshaft forging process, the clamps generally only serve a fixing function and lack an effective protective structure. This can easily lead to two types of problems in actual production: First, the clamping force is difficult to distribute reasonably. If the operator tightens the clamp excessively to prevent the workpiece from sliding under high temperature and high pressure, it will cause the clamp itself to be subjected to concentrated force and fatigue damage, resulting in a shortened service life. Second, when the camshaft is clamped under high pressure, the clamp metal is in direct contact with the workpiece without buffering or isolation design. This can easily form indentations or scratches on the workpiece surface, which not only affects the surface accuracy and aesthetics, but may also become stress concentration points in subsequent use, reducing the fatigue life of the parts and the overall reliability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a clamping device for automotive camshaft forging, comprising a docking flange for docking with a robotic arm to achieve automated operation, and a support base fixedly installed on one side of the docking flange; a clamping assembly fixedly installed on the support base, and the clamping assembly being electrically connected to the robotic arm control system to perform controlled clamping actions; a fixing plate fixed to the clamping portion of the clamping assembly; and a contact plate slidably installed inside the fixing plate via a spring telescopic rod. In use, the two contact plates are controlled by the clamping assembly to clamp the automotive camshaft forging material, and the spring telescopic rod maintains elastic protection of the automotive camshaft forging material.

[0006] In at least some embodiments, the clamping assembly includes a motor fixed inside the support base, and a long lead screw is fixedly connected to the output end of the motor.

[0007] In at least some embodiments, a lifting seat that is slidably installed inside the support base is screwed to the long lead screw and is controlled by the rotation of the long lead screw to perform lifting and lowering actions.

[0008] In at least some embodiments, a second rotating plate and a third rotating plate are rotatably mounted on both sides of the lifting seat, a first rotating plate rotatably mounted on the upper part of the support seat is rotatably connected to the second rotating plate, a clamping plate is rotatably mounted on the second rotating plate and the third rotating plate, and a fixing plate is fixedly mounted on the inner side of the clamping plate.

[0009] In at least some embodiments, the spring telescopic rod includes a fixed tube fixed to the fixed plate, a sliding rod slidably mounted on one side of the fixed tube via a spring, the sliding rod being fixedly connected to the contact plate, and a guide rod fixed to the outside of the contact plate being slidably connected to the fixed plate.

[0010] In at least some embodiments, a short lead screw is rotatably installed inside the fixed tube. One end of the short lead screw passes through the fixed tube and extends to the outside, where a knob is fixedly connected. The outside of the lead screw is screwed to a sliding plate that is slidably installed inside the fixed tube. The sliding plate is connected to the sliding rod through the spring. In use, the initial position of the sliding plate is changed by rotating the knob, thereby controlling the initial tension of the spring.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, automated production operations are achieved by docking the flange with the robotic arm. When the device is working, the two contact plates move closer together under the drive of the clamping assembly to clamp the camshaft forging material. At the same time, the spring telescopic rod plays a buffering and elastic compensation role, so that the clamping force can be automatically adjusted within the range, thereby avoiding indentations or scratches on the workpiece surface caused by excessive rigid clamping. While ensuring stable workpiece clamping and preventing slippage, the device effectively disperses and buffers stress using the principle of elastic protection. This not only extends the service life of the fixture but also improves the surface quality and yield of camshaft forgings. Through the combination of automated control and elastic protection, this device achieves stable, safe, and efficient clamping, making it suitable for the mass production and automated forging of modern automotive camshafts.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Implementation examples, based on Figures 1-4 As shown in the figure, the present invention provides a clamping device for forging automotive camshafts, including a docking flange 1 for docking with a robotic arm to achieve automated operation, a support base 2 fixedly installed on one side of the docking flange 1, a clamping assembly 3 fixedly installed on the support base 2 and used for electrically connecting with the robotic arm control system to perform controlled clamping actions, a fixing plate 5 fixed on the clamping part of the clamping assembly 3, and a contact plate 6 slidably installed inside the fixing plate 5 via a spring telescopic rod 7. In use, the two contact plates 6 are controlled by the clamping assembly 3 to perform clamping actions on the automotive camshaft forging material, and the spring telescopic rod 7 maintains elastic protection for the automotive camshaft forging material.

[0017] The aforementioned clamping device for forging automotive camshafts connects with a robotic arm via a docking flange 1 to achieve automated production operations. The support base 2 serves as the bearing foundation, securely installing the clamping assembly 3 and electrically connecting it to the robotic arm control system, thereby enabling precise adjustment of the clamping force according to the forging process requirements. The clamping part of the clamping assembly 3 is fixed with a fixing plate 5, and a contact plate 6 is installed on the inner side of the fixing plate 5 via a spring telescopic rod 7. The contact plate 6 can generate a certain elastic displacement during the clamping action. When the device is working, the two contact plates 6 approach each other synchronously under the drive of the clamping assembly 3 to clamp the camshaft forging material. At the same time, the spring telescopic rod 7 plays a buffering and elastic compensation role, so that the clamping force can be automatically adjusted within the range, thereby avoiding indentations or scratches on the workpiece surface caused by excessive rigid clamping. While ensuring the workpiece is securely clamped and preventing slippage, the elastic protection principle is used to effectively disperse and buffer stress, which not only extends the service life of the fixture, but also improves the surface quality and yield of camshaft forgings.

[0018] In this embodiment, the clamping assembly 3 includes a motor 305 fixed inside the support base 2. A long lead screw 306 is fixedly connected to the output end of the motor 305. A lifting seat 302 slidably installed inside the support base 2 is screwed to the long lead screw 306 and is controlled by the rotation of the long lead screw 306 to perform lifting and lowering actions. A second rotating plate 303 and a third rotating plate 307 are rotatably installed on both sides of the lifting seat 302, respectively. A first rotating plate 301 rotatably installed on the upper part of the support base 2 is rotatably connected to the second rotating plate 303. A clamping plate 304 is rotatably installed on the second rotating plate 303 and the third rotating plate 307. A fixing plate 5 is fixedly installed inside the clamping plate 304.

[0019] Automatic clamping control is achieved through the linkage structure of motor 305, long lead screw 306, lifting seat 302, and multiple sets of rotating plates and clamping plates 304.

[0020] Specifically, the motor 305 is fixed inside the support base 2, and its output end is fixedly connected to the long lead screw 306. When the motor 305 rotates, it drives the long lead screw 306 to rotate synchronously. The lifting seat 302 is connected to the long lead screw 306 by screw connection, so that the precise lifting action is achieved inside the support base 2 under the rotation of the lead screw.

[0021] The lifting seat 302 is rotatably mounted on both sides with a second rotating plate 303 and a third rotating plate 307 respectively. The first rotating plate 301 is set on the upper part of the support seat 2 and is rotatably connected with the second rotating plate 303. When the lifting seat 302 rises or falls, it drives the second rotating plate 303 and the third rotating plate 307 to rotate, thereby driving the clamping plates 304 at both ends of the rotating plates to move closer or open synchronously, completing the clamping or releasing action.

[0022] The fixing plate 5, which is fixed inside the clamping plate 304, provides direct contact support for the workpiece. It can be seen that the structure cleverly achieves synchronous control of the clamping plate 304 under the single drive of the motor 305 through the transmission linkage between the lead screw lifting and the multi-rotor plate. This makes the clamping action both stable and precise, and can meet the reliable clamping and rapid release requirements of automotive camshaft forging workpieces.

[0023] In this embodiment, the spring telescopic rod 7 includes a fixed tube 701 fixed on the fixed plate 5. A slide rod 702 is slidably installed on one side of the fixed tube 701 via a spring. The slide rod 702 is fixedly connected to the contact plate 6. A guide rod 4 fixed on the outside of the contact plate 6 is slidably connected to the fixed plate 5. A short lead screw 704 is rotatably installed inside the fixed tube 701. One end of the short lead screw 704 passes through the fixed tube 701 and extends to the outside, where a knob 703 is fixedly connected. The outside of the lead screw is screwed to a sliding plate 705 slidably installed inside the fixed tube 701. The sliding plate 705 is connected to the slide rod 702 via a spring. In use, the initial position of the sliding plate 705 is changed by rotating the knob 703, thereby controlling the initial tension of the spring.

[0024] The adjustable initial tension of the spring is achieved by combining components such as the fixed tube 701, slide bar 702, guide rod 4, short lead screw 704, and slide plate 705.

[0025] Specifically, one end of the fixed tube 701 is fixedly connected to the fixed plate 5 as an integral support structure. The slide rod 702 is slidably installed inside the fixed tube 701 by means of a spring, and its outer end is fixed to the contact plate 6, so that the contact plate 6 can generate elastic displacement during the clamping process.

[0026] To ensure the stability of the slide bar 702 during reciprocating motion, a guide rod 4 that slides with the fixed plate 5 is also provided on the outer side of the contact plate 6 to prevent deviation. A short lead screw 704 is rotatably installed inside the fixed tube 701. One end of the lead screw passes through the fixed tube 701 and is fixedly connected to the knob 703. When in use, the operator can directly rotate the knob 703 to drive the short lead screw 704 to rotate. The short lead screw 704 is threadedly connected to the sliding plate 705, which is slidably mounted inside the screw. Therefore, during rotation, the sliding plate 705 is moved back and forth along the interior of the fixed tube 701. The sliding plate 705 and the slide rod 702 are connected by a spring. When the position of the sliding plate 705 changes, the initial tension or compression of the spring changes accordingly, thereby adjusting its initial tension. In this way, when clamping the workpiece, the elastic protective force provided by the contact plate 6 can be precisely adjusted according to the needs, so as to achieve both a stable clamping and the prevention of damage to the workpiece surface.

[0027] The working principle of this utility model is as follows: The flange 1 is connected to the robotic arm to achieve automated production operations. The support base 2 serves as the bearing foundation, securely installing the clamping assembly 3 and electrically connecting it to the robotic arm control system. This allows for precise adjustment of the clamping force according to the forging process requirements. A fixing plate 5 is fixed to the clamping part of the clamping assembly 3. A contact plate 6 is installed inside the fixing plate 5 via a spring telescopic rod 7. The contact plate 6 can generate a certain elastic displacement during clamping. When the device is working, the two contact plates 6 move closer synchronously under the drive of the clamping assembly 3 to clamp the camshaft forging material. Simultaneously, the spring telescopic rod 7 acts as a buffer and elastic compensation, allowing the clamping force to be automatically adjusted within a range, thus avoiding indentations or scratches on the workpiece surface caused by excessive rigid clamping. While ensuring stable workpiece clamping and preventing slippage, the elastic protection principle effectively disperses and buffers stress, not only extending the service life of the fixture but also improving the surface quality and yield of the camshaft forging.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
