Description

Technical Field

[0001] This utility model relates to the technical field of tooling technology in machining processes, and in particular to an integrated tooling for shaping and inspecting long shaft workpieces. Background Technology

[0002] For long shaft workpieces, bending deformation is highly likely to occur during forging and heat treatment. Excessive bending deformation can lead to excessive subsequent processing, disrupting the production rhythm of the entire production line, reducing production efficiency, and in some cases, making the workpiece unprocessable and scrapped, resulting in significant economic losses. Therefore, long shaft workpieces need to be straightened after heat treatment. Currently, the deformation detection method for long shaft workpieces is mostly based on a combination of a large runout gauge and a lever gauge to detect radial runout. The degree of bending deformation of the workpiece is judged by the radial runout value. The general process is as follows: the workpiece is straightened on a straightening machine, removed and installed on a runout gauge for runout detection. If the runout value is too large, it is installed back on the straightening machine for straightening and re-testing, and the process is repeated until the radial runout value meets the design requirements. The entire process is labor-intensive, time-consuming, and has very low work efficiency. If the workpiece is produced in large quantities, it will seriously disrupt the production rhythm of the entire production line, greatly reduce overall production efficiency, and cause huge economic losses. Utility Model Content

[0003] The purpose of this invention is to solve the problems of high labor intensity, long time consumption, and low work efficiency in the shaping and inspection of long shaft workpieces in the prior art, and to propose an integrated tooling for shaping and inspecting long shaft workpieces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A long-axis workpiece shaping and inspection integrated fixture includes a fixture base with symmetrically arranged clamping parts at both ends. The working end of the clamping part coincides with the axis of the long-axis workpiece. The fixture also includes: a V-shaped support block disposed on the fixture base for supporting the long-axis workpiece to be straightened; a pad block that moves freely along the axial direction and is placed below the part to be straightened; a pressure head disposed above the pad block to clamp the long-axis workpiece, the pressure head being driven to move up and down by a press; and a lever gauge that is attracted to the side edge of the fixture base by its own permanent magnet for detecting the radial runout of the long-axis workpiece.

[0006] To ensure that the workpiece does not shift during the workpiece straightening process, preferably, the surface of the tooling base has a mounting groove, the V-shaped support block is embedded in the mounting groove of the tooling base, and is fastened with bolts to achieve relative positioning and fixation.

[0007] To achieve precise local alignment, the pad is further aligned vertically with the pressure head.

[0008] To prevent the workpiece from slipping during the straightening process, the pad is further provided with a shim on the surface of the pad block near the long shaft type workpiece.

[0009] To ensure a smooth and reliable process for tightening and loosening the workpiece, preferably, the tightening part includes a tailstock and an ejector pin. Two tailstocks are provided and are fixedly installed at both ends of the tooling base. A drive cylinder is mounted on the tailstock. The ejector pins are respectively mounted in the center holes of the two tailstocks and can move along the axis of the center hole. The tightening and loosening of the workpiece is completed by the drive cylinder.

[0010] To enhance the adaptability and reliability of the workpiece clamping process, the tailstock further includes a sliding groove inside.

[0020] Example:

[0021] Reference Figures 1-4 A long-shaft workpiece forming and inspection integrated fixture includes a rectangular fixture base 1, which serves as the basic platform for the entire fixture. It is fixed to the lower working platform of a forming press by at least four T-bolts, ensuring the overall stability and accuracy of the fixture. The fixture base 1 has symmetrically arranged clamping parts 5 at both ends, with the working end of the clamping part 5 coinciding with the axis of the long-shaft workpiece. The fixture also includes: a V-shaped support block 2, mounted on the fixture base 1 to support the long-shaft workpiece to be straightened; a pad block 3, freely movable along the axial direction and placed below the part to be straightened; a pressure head 4, positioned above the pad block 3 to clamp the long-shaft workpiece, driven up and down by the press; and a lever gauge 6, which is attracted to the side edge of the fixture base 1 by its permanent magnet, facilitating operator adjustment of the inspection position for detecting the radial runout of the long-shaft workpiece, allowing for accurate measurement of the radial runout value at different positions. The lever gauge 6 does not obstruct the loading and unloading of the workpiece.

[0022] Place the long shaft workpiece on the V-shaped support block 2. Place a pad block 3 below the straightening section as needed. Start the forming press, causing the pressure head 4 to move downwards and squeeze the workpiece. After the workpiece is deformed by the squeeze, its lower part contacts the pad block 3, effectively preventing over-forming and workpiece scrap. After one forming and straightening operation, move the worktable of the forming press to its highest point, and the clamping part 5 clamps the long shaft workpiece, causing it to detach from the V-shaped support block 2. At this time, adjust the detection needle of the lever gauge 6 to the position to be tested on the workpiece. Gently rotate the workpiece and observe the range of change of the dial pointer of the lever gauge 6 to measure the radial runout value at this position. If the radial runout value after forming and straightening does not meet the drawing requirements, operate the drive clamping part 5 again to retract. The workpiece slowly slides into the V-shaped support block 2 under gravity. Then press the power switch of the forming press to perform another forming and straightening operation until the radial runout of the workpiece meets the drawing requirements.

[0023] The tooling base 1 has a mounting groove 101 on its surface. The V-shaped support block 2 is embedded in the mounting groove 101 of the tooling base 1 and is fastened with bolts to achieve relative positioning and fixation.

[0024] This installation method not only provides high-precision positioning, but also enhances the stability of the V-shaped support block 2, ensuring that no displacement occurs during the workpiece straightening process. At the same time, the bolt fastening design allows the V-shaped support block 2 to be adjusted or replaced according to actual needs, improving the maintenance convenience and service life of the tooling.

[0025] To ensure that the pressure applied by the pressure head 4 is evenly transmitted to the pad block 3, the pad block 3 is aligned vertically with the pressure head 4, thereby achieving precise local straightening and avoiding workpiece deformation or damage due to uneven pressure distribution, thus improving the reliability of the tooling and the quality of workpiece straightening.

[0026] The pad 3 has a shim 301 on its surface near the long shaft workpiece to increase the friction between it and the workpiece and prevent the workpiece from slipping during the straightening process.

[0027] The clamping part 5 mainly includes a tailstock 501, an ejector pin 502, and a drive cylinder 503. There are two tailstocks 501, which are fixedly installed at both ends of the tooling base 1. Each tailstock 501 provides a stable mounting point to ensure the accuracy of the ejector pin 502. There are two ejector pins 502, which are respectively assembled in the center holes of the two tailstocks 501 and can move along the axis of the center hole. They are used to directly contact and clamp or loosen long shaft-type workpieces. The drive cylinder 503 is fixedly installed on the tailstock 501 and connected to the ejector pin 502. It is used to drive the ejector pin 502 to complete the clamping and loosening action of the workpiece. The drive cylinder 503 provides power to ensure that the clamping and loosening process of the workpiece is smooth and reliable.

[0028] The clamping part 5 includes a tailstock 501 and an ejector pin 502. There are two tailstocks 501, which are fixedly installed at both ends of the tooling base 1. A drive cylinder 503 is mounted on the tailstock 501. The ejector pin 502 is respectively mounted in the center hole of the two tailstocks 501 and can move along the axis of the center hole. The drive cylinder 503 completes the clamping and loosening action of the workpiece, ensuring the smoothness and reliability of the clamping and loosening action, so that the stability of the workpiece is guaranteed during the inspection process, and the loading and unloading operation of the workpiece is also simplified.

[0029] The tailstock 501 has a sliding groove 506 inside. The output end of the drive cylinder 503 extends into the sliding groove 506 and is fixedly installed with a pressure plate 505. A ball 504 is provided in the sliding groove 506. The ball 504 abuts against the ejector pin 502 and the pressure plate 505 respectively, allowing the ejector pin 502 to be finely adjusted within a certain range, which enhances the adaptability and reliability of the workpiece clamping process. The sliding groove 506 is a cylindrical cavity, and the diameter of the central hole where the ejector pin 502 is located is larger than the diameter of the ejector pin 502. This ensures that the ejector pin 502 can move smoothly along the central hole to realize the clamping and loosening action of the workpiece. This design not only ensures the flexibility of the ejector pin 502's movement, but also ensures the accuracy and stability of its movement.

[0030] Long shaft-type workpieces are placed on V-shaped support blocks 2, and pad blocks 3 are placed below the straightening section as needed. Ensure that pad blocks 3 and pressure heads 4 are vertically aligned to prepare for the subsequent straightening operation. Start the forming press, causing pressure heads 4 to move downwards and compress the workpiece. Because pressure heads 4 and pad blocks 3 are vertically aligned, the workpiece deforms under compression and contacts pad blocks 3 at the bottom, effectively preventing over-forming and workpiece scrap. After one straightening operation, the worktable on the forming press is moved to its highest point. Press the cylinder drive button, driving cylinder 503 to drive ball 504, which in turn extends ejector pin 502, pressing against the long shaft-type workpiece to disengage it. V-shaped support block 2. At this time, adjust the detection needle of lever gauge 6 to align with the position to be detected on the workpiece, gently rotate the workpiece to be detected, observe the range of change of the dial pointer of lever gauge 6, and measure the radial runout value at this position. If the radial runout value after shaping and straightening does not meet the requirements of the drawing, operate the drive cylinder 503 again to retract the ejector pin 502. The workpiece slowly slides into V-shaped support block 2 under the action of gravity. Then press the power switch of the shaping press to perform the shaping and straightening action again until the radial runout of the workpiece meets the requirements of the drawing.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
