Description

Technical Field

[0001] This utility model relates to the field of straightness calibration technology, and in particular to a straightness calibration device for pin-type metal parts. Background Technology

[0002] A straightness calibration device is a specialized tool or equipment used to detect and calibrate whether a workpiece, equipment, or moving mechanical part maintains a precise straightness in the straight direction. It is commonly used in machine tool guideways, optical instruments, precision mechanical assembly, and engineering measurement. This device uses methods such as laser interferometers, optical collimators, electronic levels, rulers, or mechanical measuring elements to detect straightness deviations of the object being measured, and achieves calibration through data analysis and adjustment. Using a straightness calibration device can effectively eliminate deviations caused by guideway wear, assembly errors, or machining deformation, ensuring the stability of equipment operation and the accuracy of machined parts, thereby improving overall production quality and reliability.

[0003] During the manufacturing process of metal parts such as pins, the straightness of the parts needs to be calibrated and tested using specialized monitoring instruments. Currently, most existing straightness calibration devices use V-blocks to support and place the parts under test. This design cannot be flexibly adjusted according to the length specifications of the parts. Furthermore, when using monitoring instruments to test the straightness of these parts, manual rotation and adjustment are required, which not only affects the test results but also poses a risk of finger injuries during manual adjustment. Therefore, these methods have certain limitations in their application.

[0004] Based on this, we propose a straightness calibration device for pin-type metal parts to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a straightness calibration device for pin-type metal parts, which can solve the problems of existing straightness calibration devices when testing pin-type metal parts, where the support component cannot be flexibly adjusted according to the length specifications, requires manual flipping and adjustment, resulting in unstable test results and the risk of finger pinching.

[0007] To solve the above-mentioned technical problems, this utility model provides a straightness calibration device for pin-type metal parts, adopting the following technical solution: It includes a support base plate, a calibration and detection assembly mounted on the top of the support base plate, two sets of support brackets connected to the top of the support base plate near the calibration and detection assembly, and a pin workpiece connected between the two sets of support brackets. Each support bracket includes a support frame, a guide roller connected to the top of the support frame via a bearing, a first pulley connected to one side of each of the two sets of guide rollers, a second pulley connected to the middle of one side of the support frame via a bearing, and transmission belts connected between the second pulleys and the two sets of first pulleys.

[0008] Optionally, a guide plate is installed at the bottom of the support frame, and a through-hole with positive and negative screw holes is provided in the middle of the guide plate.

[0009] Optionally, the calibration and testing assembly includes a fixed base, an adjusting rod connected to the top of the fixed base, a sliding adjuster connected to the middle of the adjusting rod, a support arm hinged to one side of the sliding adjuster, and a straightness tester provided at one end of the support arm.

[0010] Optionally, a first guide rail is mounted on the top of one end of the support base, and an adjustment base is slidably connected to the top of the first guide rail. The adjustment base and the fixed base are structurally matched and are fixedly connected.

[0011] Optionally, a second guide rail is mounted on the top of the end of the support substrate away from the first guide rail. An optical detection module is provided in the middle of the top of the second guide rail. A limiting groove is formed in the middle of the second guide rail. A positive and negative screw is connected to the middle of the limiting groove through a bearing. An adjustment handwheel is also provided at one end of the positive and negative screw and the second pulley.

[0012] Optionally, the limiting groove and the guide plate are in a sliding fit, and the positive and negative screws and the positive and negative screw holes are in a threaded fit.

[0013] In summary, this utility model has at least one of the following beneficial effects:

[0014] 1. The straightness calibration device designed in this scheme mainly consists of a support base plate, calibration and detection components, support frame components, and pin shaft workpieces. The support frame body, through the sliding fit between the limiting slide groove and the guide plate, and the threaded fit structure between the positive and negative screws and the positive and negative screw holes, can move and adjust the two sets of support frames mounted on the top of the second guide rail in relative or opposite directions. This allows for flexible adjustment of the distance between the two sets of support frames according to the length specifications of the metal parts such as pin shaft workpieces to be tested. At the same time, by utilizing the cooperation between the support frame body, guide roller, first pulley, second pulley, and transmission belt, the metal parts such as pin shaft workpieces placed between the tops of the two sets of support frames can also be easily flipped and adjusted. This adjustment process does not require manual hands to directly contact the metal parts such as pin shaft workpieces for flipping and adjustment, which not only improves the flexibility of the equipment in detecting metal parts such as pin shaft workpieces, but also avoids accidents such as bumps and pinches to the hands of workers during the flipping and adjustment process.

[0015] 2. The straightness calibration device designed in this scheme works in conjunction with the adjustment base and support frame components installed on the top of the first guide rail. Since the adjustment base is slidably connected to the first guide rail and fixedly connected to the fixed base, the adjustment base, which is equipped with a sliding adjuster, support arm, and straightness tester, can be slidably limited to the top of the first guide rail. This allows the device to flexibly adjust the position of the straightness tester for calibration and testing of metal parts such as pins. Moreover, the adjustment base and the fixed base adopt a detachable structural design, which allows the device to be disassembled, connected, repaired, and replaced according to the usage conditions. This can effectively improve the flexibility and practicality of the device in the field of straightness calibration technology. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Refer to Figures 1 to 4 This utility model provides an embodiment of a straightness calibration device for pin-type metal parts, including a support base plate 1. A calibration and detection component 2 is mounted on the top of the support base plate 1. Two sets of support brackets 3 are connected to the top of the support base plate 1 near the calibration and detection component 2. A pin workpiece 4 is also connected between the two sets of support brackets 3. Each support bracket 3 includes a support frame 5. A guide roller 6 is connected to the top of the support frame 5 via a bearing. A first pulley 7 is connected to one side of each of the two sets of guide rollers 6. A second pulley 8 is connected to the middle of one side of the support frame 5 via a bearing. The second pulley 8 is also connected to the two sets of first pulleys 7. With a transmission belt 9, the straightness calibration device, through the sliding fit between the limiting slide groove 21 and the guide plate 10, and the threaded fit between the positive and negative screws 22 and the positive and negative screw holes 11, can adjust the relative or opposite directions of the two sets of support frames 5 mounted on the top of the second guide rail 19. The distance between the two sets of support frames 5 can be flexibly adjusted according to the length specifications of the metal parts such as the pin shaft workpiece 4 to be tested. Through the cooperation of the support frame 5, guide roller 6, first pulley 7, second pulley 8 and transmission belt 9, the metal parts such as the pin shaft workpiece 4 placed between the tops of the two sets of support frames 5 can be flipped and adjusted.

[0024] A guide plate 10 is installed at the bottom of the support frame 5. A through-hole 11 (positive and negative screw holes 11) is provided in the middle of the guide plate 10. The guide plate 10 and the through-hole 11 at the bottom of the support frame 5 are used for limiting the connection and adjustment between the two sets of support frames 5 and the first guide rail 17. The calibration and testing assembly 2 includes a fixed base 12. An adjusting rod 13 is connected to the top of the fixed base 12. A sliding adjuster 14 is connected to the middle of the adjusting rod 13. A support arm 15 is damped and hinged to one side of the sliding adjuster 14. A straightness tester 16 is also provided at one end of the support arm 15. The straightness tester 16, through the cooperation of the fixed base 12, adjusting rod 13, sliding adjuster 14, and support arm 15, can achieve flexible adjustment and stable support according to usage requirements under the damping hinge action of the support arm 15. The device can perform precise detection based on the position of the pin workpiece 4, enabling efficient calibration and detection of the straightness of the pin workpiece 4 by the straightness detector 16. A first guide rail 17 is installed on the top of one end of the support base 1. An adjustment base 18 is slidably connected to the top of the first guide rail 17. The adjustment base 18 and the fixed base 12 are structurally matched and fixedly connected. Through the slid connection between the adjustment base 18 and the first guide rail 17, and the fixed connection between the adjustment base 18 and the fixed base 12, the adjustment base 18, which is equipped with a sliding adjuster 14, a support arm 15, and a straightness detector 16, can be slidably limited to the top of the first guide rail 17. This allows the device to flexibly adjust the position of the straightness detector 16 for calibration and detection of metal parts such as the pin workpiece 4.

[0025] A second guide rail 19 is mounted on the top of the end of the support base plate 1 furthest from the first guide rail 17. An optical detection module 20 is located in the center of the top of the second guide rail 19. A limiting groove 21 is formed in the center of the second guide rail 19. A positive and negative screw 22 is connected to the center of the limiting groove 21 via a bearing. Adjusting handwheels 23 are respectively provided at one end of the positive and negative screw 22 and one end of the second pulley 8. The limiting groove 21 and the positive and negative screw 22 formed inside the second guide rail 19 are used for limiting the connection between the two sets of support frames 5 and the first guide rail 17. The adjustment mechanism allows for a sliding fit between the limiting slide groove 21 and the guide plate 10, and a threaded fit between the positive and negative screws 22 and the positive and negative screw holes 11. Through this structural design, the two sets of support frames 5 mounted on the top of the second guide rail 19 can be moved and adjusted in relative or opposite directions. Furthermore, the distance between the two sets of support frames 5 can be flexibly adjusted according to the length specifications of the metal parts such as the pin workpiece 4 to be inspected.

[0026] Working Principle: The straightness calibration device designed in this scheme mainly consists of a support base plate 1, a calibration and detection component 2, a support frame component 3, and a pin workpiece 4. The support frame 5, through the sliding cooperation between the limiting slide groove 21 and the guide plate 10, and the threaded cooperation between the positive and negative screws 22 and the positive and negative screw holes 11, can move and adjust the two sets of support frames 5 mounted on the top of the second guide rail 19 in relative or opposite directions. The distance between the two sets of support frames 5 can be flexibly adjusted according to the length specifications of the metal parts such as the pin workpiece 4 to be tested. Through the cooperation of the support frame 5, guide roller 6, first pulley 7, second pulley 8 and transmission belt 9, it is also convenient to flip and adjust the metal parts such as the pin workpiece 4 that are limited and placed between the tops of the two sets of support frames 5. This adjustment process does not require manual contact with the metal parts such as the pin workpiece 4 for flipping and adjustment, which can improve the flexibility of the equipment in detecting metal parts such as the pin workpiece 4, and at the same time avoid accidents such as bumps and pinches to the workers' hands when flipping and adjusting the metal parts such as the pin workpiece 4.

[0027] The straightness calibration device designed in this scheme uses an adjusting base 18 and a support frame assembly 3 installed on the top of the first guide rail 17. Since the adjusting base 18 is slidably connected to the first guide rail 17 and fixedly connected to the fixed base 12, the adjusting base 18, which is equipped with a sliding adjuster 14, a support arm 15, and a straightness detector 16, can be slidably limited to the top of the first guide rail 17. This allows the device to flexibly adjust the position of the straightness detector 16 for calibration and testing of metal parts such as pin workpieces 4. Furthermore, the adjusting base 18 and the fixed base 12 adopt a detachable structural design, which also allows the straightness detector 16 to be disassembled, connected, repaired, and replaced according to usage. When used in conjunction with the optical detection module 20, the straightness detector 16 can perform dual calibration on metal parts such as pin workpieces 4 that are flipped and adjusted between the tops of the two sets of support frames 5, which can effectively improve the accuracy of the straightness calibration of the device.
