Description

Technical Field

[0001] This utility model relates to the field of straightness inspection clamping technology, specifically a clamping fixture for machining straightness inspection. Background Technology

[0002] In the field of machining, straightness inspection is a key step in ensuring product quality. The performance of clamping fixtures directly affects the accuracy and efficiency of inspection. Traditional clamping fixtures often lack flexible and effective adjustment mechanisms when fixing inspection parts. For example, it is difficult to achieve fast and stable clamping for inspection parts of different sizes and shapes, which may cause the inspection parts to shake or shift during the inspection process, thus affecting the accuracy of the straightness inspection results and failing to meet the inspection requirements of high-precision machining. Therefore, it is necessary to constantly change the corresponding clamping tools to meet the needs of workpieces of different sizes. For example, when inspecting the straightness of different shaft parts, corresponding clamping workpieces are required to clamp shaft parts of different diameters.

[0003] In the straightness inspection process, existing clamping fixtures typically employ a single inspection method and lack precise adjustment capabilities. On the one hand, the position and angle adjustment of the inspection equipment are not flexible enough, making it difficult to accurately adapt to the actual position and inspection requirements of the inspection piece. This limits the inspection range and prevents the comprehensive and accurate inspection of the straightness of the inspection piece. On the other hand, the lack of an effective horizontal calibration device during the inspection process makes it difficult to ensure that the inspection equipment is in a horizontal state, which also adversely affects the accuracy of the straightness inspection results and reduces the reliability and effectiveness of the entire inspection work. To solve the above problems, we propose a clamping fixture for machining straightness inspection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a clamping fixture for inspecting the straightness of machining processes, thereby solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a clamping fixture for inspecting the straightness of machining, including a base plate, a platform fixedly installed on the top surface of the base plate, a lifting plate above the platform, clamping plates fixedly installed on both sides of the bottom surface of the lifting plate, a support platform on the right side of the base plate, and a lifting platform installed on the support platform, an mounting platform fixedly installed on the top of the lifting platform, a housing on the mounting platform, an adjusting plate inside the housing, a laser beam fixedly installed on the top surface of the adjusting plate, and spirit levels installed on both sides of the top surface of the adjusting plate and on both sides of the laser beam.

[0006] As a preferred technical solution of this utility model, an mounting plate is fixedly installed on one side of the top surface of the base plate, and a second hydraulic rod is fixedly installed in the middle of the top surface of the mounting plate. The output end of the second hydraulic rod passes through the top of the mounting plate and is fixedly connected to the top surface of the lifting plate. The vertical cross-section of the mounting plate is L-shaped.

[0007] As a preferred embodiment of the present invention, the support platform has an internal cavity, the lifting platform is located on the top of the support platform and extends through the cavity, and the left side of the support platform has a heat dissipation hole that extends through the cavity.

[0008] As a preferred embodiment of this utility model, the bottom of the lifting platform is provided with a groove, and a first hydraulic rod is fixedly installed on the bottom inner wall of the cavity opened by the support platform. The output end of the first hydraulic rod is fixedly connected to the top inner wall of the groove opened at the bottom of the lifting platform.

[0010] As a preferred technical solution of this utility model, the adjusting plate is slidably connected in the receiving groove opened at the top of the housing, the mounting platform has a cavity inside, and a worm gear is rotatably connected to the right inner wall of the cavity inside the mounting platform, which passes through and extends to the left side of the mounting platform. A handwheel is installed at the end of the worm gear located outside the mounting platform.

[0011] As a preferred technical solution of this utility model, a rotating shaft is rotatably connected to the inner walls of the cavity opened inside the mounting platform on the side that are close to each other, and a worm wheel and a gear are respectively installed on both sides of the outer ring of the rotating shaft.

[0012] As a preferred embodiment of this utility model, the top of the shelf is provided with the inspection piece to be inspected, and the top surface of the shelf is provided with insertion holes on both sides for the lower part of the clamp to be inserted, and the clamp is a V-shaped plate.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Example 1: Please refer to Figures 1-4A machining straightness inspection clamping fixture includes a base plate 1. The base plate 1 is first placed stably on the worktable, and the inspection piece 20 to be inspected is placed on the shelf 3. The inspection piece 20 can be a cylindrical workpiece such as a shaft, or a rectangular workpiece. Since the top surface of the shelf 3 has insertion holes on both sides for the lower part of the clamping plate 2 to be inserted, it can clamp smaller workpieces. The second hydraulic rod 16, which is fixedly installed in the middle of the top surface of the mounting plate 15, is activated. The output end of the second hydraulic rod 16 passes through the top of the mounting plate 15 and is fixedly connected to the top surface of the lifting plate 14. As the output end of the second hydraulic rod 16 extends downward, it pushes the lifting plate 14 down, thereby driving the V-shaped clamping plates 2, which are fixedly installed on both sides of the bottom surface of the lifting plate 14, to move downward, thereby clamping and fixing the workpiece such as the inspection piece 20. The insertion holes on the shelf 3 enable the clamping plates 2 to clamp and fix smaller workpieces.

[0019] Next, the first hydraulic rod 6, which is fixedly installed on the inner wall of the cavity at the bottom of the support platform 7, is activated. The output end of the first hydraulic rod 6 is fixedly connected to the inner wall of the groove at the bottom of the lifting platform 5. The output end of the first hydraulic rod 6 extends upward, pushing the lifting platform 5 to move upward on the top of the support platform 7. The lifting platform 5 drives the mounting platform 10, which is fixedly installed on the top, to rise. The housing 11 on the mounting platform 10 and the laser beam 12 on the top of the adjusting plate 13 inside the housing 11 also rise accordingly. The laser beam 12 is adjusted to a suitable height position so as to perform straightness inspection on the inspection piece 20. At the same time, the level bubble 4 installed on the top surface of the adjusting plate 13 and on both sides of the laser beam 12 is observed to ensure that the laser beam 12 is in a horizontal state, thus ensuring the accuracy of the inspection.

[0020] Example 2: Please refer to Figures 1-4 When it is necessary to adjust the angle of the laser beam 12 to ensure that the laser beam 12 is horizontal, the handwheel 8 installed at one end of the worm 9 located on the left side of the mounting platform 10 can be rotated. Since the worm 9 is rotatably connected to the right inner wall of the cavity opened inside the mounting platform 10 and extends through to the left side of the mounting platform 10, the rotation of the handwheel 8 drives the worm 9 to rotate.

[0021] On the rotating shaft rotatably connected to the inner walls of the cavity inside the mounting platform 10, a worm gear 17 and a gear 18 are respectively installed. The worm gear 17 meshes with the worm 9. The rotation of the worm 9 drives the worm gear 17 to rotate, which in turn drives the rotating shaft to rotate. The gear 18 on the rotating shaft also rotates. Since the gear 18 meshes with the rack 19 fixedly installed on the semi-circular bottom surface of the adjusting plate 13, the rotation of the gear 18 drives the rack 19 to move, thereby allowing the adjusting plate 13 to slide in the receiving groove opened on the top of the housing 11. This allows the angle of the laser beam 12 on the top of the adjusting plate 13 to be adjusted, so that the laser beam 12 is in a horizontal state, ensuring the accuracy of the inspection. When the adjusting plate 13 is adjusted to the initial horizontal state, the adjusting plate 13 and the top surface of the platform 3 are on the same horizontal plane, ensuring that the platform 3 is in a horizontal state.

[0022] Example 3: Please refer to Figures 1-4 For larger inspection pieces 20, they are first placed on the platform 3. Based on the height of the inspection piece 20, the height of the lifting platform 5 is adjusted by the first hydraulic rod 6 so that the mounting platform 10 and the laser beam 12 are in a suitable height range.

[0023] Then, based on the width of the inspection piece 20, the extension and retraction of the second hydraulic rod 16 is controlled, and the descent distance of the lifting plate 14 is adjusted so that the V-shaped clamp 2 can accurately clamp both sides of the inspection piece 20. Due to the design of the V-shaped clamp 2, a good clamping effect can be achieved for inspection pieces 20 of different widths.

[0024] During the inspection process, if a slight angular deviation is found in the laser beam 12 due to prolonged use of the device or external factors, it can be detected in time by observing the level bubble 4. Then, following the method in Example 2, the handwheel 8 is rotated, and the angle of the laser beam 12 on the adjustment plate 13 is finely adjusted by utilizing the transmission relationship of the worm 9, worm wheel 17, gear 18 and rack 19 to ensure the accuracy of the straightness inspection.

[0025] The first hydraulic rod 6 and other components inside the support platform 7 will generate heat during long-term operation. The left side of the support platform 7 has heat dissipation holes that penetrate and extend into the cavity of the support platform 7. These heat dissipation holes can promote air circulation and dissipate the heat generated inside the support platform 7, ensuring that the first hydraulic rod 6 and other components work in a suitable temperature environment, reducing performance degradation or failure caused by overheating, thereby enabling continuous and stable straightness inspection of the clamping fixture and improving inspection efficiency.

[0026] Implementation effect: By using the platform 3 set on the base plate 1 and the V-shaped clamps 2 on both sides of the bottom of the lifting plate 14 and the second hydraulic rod 16, inspection pieces 20 of different sizes can be clamped quickly and stably. The operation is convenient and avoids the need to change different clamping mechanisms when clamping different workpieces, thus improving work efficiency.

[0027] Through the transmission structure of handwheel 8, worm 9, worm gear 17, gear 18 and rack 19, the angle of laser beam 12 can be precisely adjusted to further improve inspection accuracy. The level bubble 4 installed on the adjustment plate 13 facilitates observation of whether the laser beam 12 is horizontal, ensuring the accuracy of inspection. It can also be used to detect the surface flatness of frustum-shaped or conical parts. At the same time, the first hydraulic rod 6 on the support platform 7 drives the lifting platform 5 to rise and fall, which can flexibly adjust the height of the mounting platform 10 and the laser beam 12 to meet the inspection needs of different heights, greatly improving the convenience of straightness inspection.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
