Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, and more specifically, to a modular measuring positioning fixture. Background Technology

[0002] In the measurement process of industrial production, accurate positioning and stable fixation of workpieces are the key prerequisites for ensuring measurement accuracy. In the traditional workpiece fixing method, glue is often used to stick the workpiece to the top of the measuring platform. This method can fix the workpiece in the short term, but it has many insurmountable drawbacks. Firstly, after removing the workpiece, glue residue is easily left on the top of the platform. This residue will cause the platform surface to be uneven. When measuring other workpieces in the future, the uneven surface will make the workpieces unstable, which will affect the consistency of the measurement benchmark, reduce the measurement accuracy, and may even lead to large deviations in the measurement data, posing a hidden danger to production quality control. Secondly, the removal process of adhesive-fixed fixtures is very inconvenient. It requires the use of tools to scrape it off, which not only consumes a lot of time and manpower, but may also scratch the surface of the measuring platform during the scraping process, further damaging the flatness of the platform and shortening its service life. Therefore, a modular measuring positioning fixture is proposed. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular measuring and positioning fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular measuring and positioning fixture, including a support platform, providing a flat and stable platform for workpiece measurement. A first guide groove is provided on one side of the top of the support platform, and multiple second guide grooves are provided on the other side of the top of the support platform. A limiting side block is provided at the top of the first guide groove, and a limiting end block is provided at the top of the second guide groove. The positions of the limiting side block and the limiting end block can be limited by the first guide groove and the second guide groove. The bottom of the limiting side block is fixedly connected to a first limiting guide block, and one side of the limiting side block is fixedly connected to a second limiting strip. A first threaded hole is opened in the middle of the limiting side block, and a first extrusion bolt is inserted in the middle of the first threaded hole. The position of the limiting side block can be adjusted by sliding the first limiting guide block inside the first guide groove. The position of the limiting side block can be fixed by rotating the first extrusion bolt to extrude the inner wall of the first guide groove, which is convenient for positioning workpieces of different sizes. The bottom of the limiting end block is fixedly connected to a second limiting guide block, and one side of the second limiting guide block is fixedly connected to a first limiting strip. A second threaded hole is opened in the middle of the limiting end block, and a second extrusion bolt is inserted in the middle of the second threaded hole. The position of the limiting end block can be adjusted by sliding the second limiting guide block inside the second guide groove. The position of the limiting end block can be fixed by rotating the second extrusion bolt to extrude the bottom wall of the inner cavity of the second guide groove, which is convenient for positioning workpieces of different sizes.

[0005] Preferably, the second guide groove is perpendicular to the first guide groove, and the inner cavity cross-sectional shape of both the second guide groove and the first guide groove is set to "T" shape. This vertically distributed guide groove design forms a cross-shaped positioning reference, which can position the workpiece from two mutually perpendicular directions, providing a structural basis for the precise fixation of the workpiece.

[0006] Preferably, the first limiting guide block and the second limiting guide block are adapted to the first guide groove and the second guide groove, respectively. The first limiting guide block is disposed in the middle of the first guide groove, and the second limiting guide block is disposed in the middle of the second guide groove. This can limit the position of the first limiting guide block and the second limiting guide block, making it convenient for sliding adjustment.

[0007] Preferably, the limiting end block and the limiting side block are in one-to-one correspondence, and the second limiting strip and the first limiting strip are located on the opposite side of the limiting side block and the limiting end block, respectively. The second limiting strip and the first limiting strip can abut against the two sides of the workpiece, thereby playing the role of lateral and end positioning.

[0008] Preferably, a nut groove is provided at the top of the inner cavity of both the first threaded hole and the second threaded hole. The screw head at one end of the first extrusion bolt and the second extrusion bolt is set inside the nut groove. The nut groove stores the top screw head of the first extrusion bolt and the second extrusion bolt, which can prevent the screw head from protruding from the surface of the limiting side block and the limiting end block, prevent the screw head from interfering with the placement and positioning of the workpiece, and ensure that the workpiece can be placed stably on the support platform.

[0009] Preferably, one end of the second extrusion bolt and the first extrusion bolt respectively penetrates the inner cavity of the second limiting guide block and the first limiting guide block and fits against the bottom wall of the inner cavity of the second guide groove and the first guide groove. When the limiting side block slides to the appropriate position, the first extrusion bolt is tightened. Through the friction between the first extrusion bolt and the bottom wall of the first guide groove, the limiting side block can be fixed in the current position to prevent it from shifting during the measurement process. When the limiting end block slides to the appropriate position, the second extrusion bolt is tightened. The limiting end block is fixed by the friction between the second extrusion bolt and the bottom wall of the second guide groove.

[0010] The technical effects and advantages of this utility model are as follows: 1. This utility model first limits the workpiece on both sides by setting limiting side blocks and limiting end blocks, ensuring that the workpiece is in an accurate position during the measurement process and improving measurement accuracy. Then, the top of the workpiece base is limited by the first limiting strip and the second limiting strip to achieve limiting and fixing, which is convenient for measurement and use. Moreover, it can be quickly placed and taken out by sliding, which is convenient for replacement and use. At the same time, the cooperation between the second guide groove and the first guide groove with the first limiting guide block and the second limiting guide block makes it easy to adjust the position of the limiting side blocks and limiting end blocks according to the size of the workpiece base, which is convenient to adjust and adapt to the use of workpiece bases of different sizes, improving the flexibility of use. 2. This utility model also features a second extrusion bolt and a first extrusion bolt that pass through the limiting end block and the limiting side block respectively and fit into the inner cavity of the second guide groove and the first guide groove, which facilitates the fixing of the position of the limiting end block and the limiting side block. The top screw heads of the first extrusion bolt and the second extrusion bolt are stored in the nut groove, which can prevent the bolt screw heads from protruding from the surface of the limiting side block and the limiting end block, prevent the screw heads from interfering with the placement and positioning of the workpiece, and ensure that the workpiece can be placed stably on the support table. In summary, through the interaction of the above-mentioned multiple functions, it is possible to ensure that the workpiece is in an accurate position during the measurement process, thereby improving measurement accuracy. Furthermore, it is possible to quickly place and remove the workpiece through sliding, facilitating replacement and improving measurement accuracy. It is also easy to adjust and adapt to workpiece bases of different sizes, thereby increasing the flexibility of use and improving measurement efficiency. Attached Figure Description

[0017] As attached Figure 1-4 The modular measuring and positioning fixture shown includes a support platform 1, which provides a flat and stable platform for workpiece measurement. A first guide groove 2 is provided on one side of the top of the support platform 1, and multiple second guide grooves 3 are provided on the other side of the top of the support platform 1. A limiting side block 4 is provided on the top of the first guide groove 2, and a limiting end block 5 is provided on the top of the second guide groove 3. The positions of the limiting side block 4 and the limiting end block 5 can be limited by the first guide groove 2 and the second guide groove 3. The bottom of the limiting side block 4 is fixedly connected to a first limiting guide block 6, and one side of the limiting side block 4 is fixedly connected to a second limiting strip 9. The middle of the limiting side block 4 is provided with a first threaded hole 10, and a first pressing bolt 11 is inserted into the middle of the first threaded hole 10. The position of the limiting side block 4 can be adjusted by sliding the first limiting guide block 6 inside the first guide groove 2. The position of the limiting side block 4 can be fixed by rotating the first pressing bolt 11 to press the inner wall of the first guide groove 2, which is convenient for positioning workpieces of different sizes. A second limiting guide block 7 is fixedly connected to the bottom of the limiting end block 5. A first limiting strip 8 is fixedly connected to one side of the second limiting guide block 7. A second threaded hole 12 is opened in the middle of the limiting end block 5. A second pressing bolt 13 is inserted in the middle of the second threaded hole 12. The position of the limiting end block 5 can be adjusted by sliding the second limiting guide block 7 inside the second guide groove 3. The position of the limiting end block 5 can be fixed by rotating the second pressing bolt 13 to press the bottom wall of the inner cavity of the second guide groove 3, which is convenient for positioning workpieces of different sizes.

[0018] As attached Figure 1-4As shown, the second guide groove 3 is perpendicular to the first guide groove 2. The inner cross-sectional shape of both the second guide groove 3 and the first guide groove 2 is set to "T" shape. This vertically distributed guide groove design forms a cross-shaped positioning reference, which can position the workpiece from two mutually perpendicular directions, providing a structural basis for the precise fixation of the workpiece. The first limiting guide block 6 and the second limiting guide block 7 are respectively adapted to the first guide groove 2 and the second guide groove 3. The first limiting guide block 6 is set in the middle of the first guide groove 2, and the second limiting guide block 7 is set in the middle of the second guide groove 3. The positions of the first limiting guide block 6 and the second limiting guide block 7 can be limited, which is convenient for sliding adjustment. The limiting end block 5 and the limiting side block 4 correspond one-to-one. The second limiting strip 9 and the first limiting strip 8 are located on the opposite side of the limiting side block 4 and the limiting end block 5, respectively. The second limiting strip 9 and the first limiting strip 8 can abut against the two sides of the workpiece, playing the role of lateral and end positioning. As attached Figure 1-4 As shown, a nut groove is provided at the top of the inner cavity of the first threaded hole 10 and the second threaded hole 12. The screw heads at one end of the first extrusion bolt 11 and the second extrusion bolt 13 are set inside the nut groove. One end of the second extrusion bolt 13 and the first extrusion bolt 11 respectively penetrates the inner cavity of the second limiting guide block 7 and the first limiting guide block 6 and fits against the bottom wall of the inner cavity of the second guide groove 3 and the first guide groove 2. The nut groove stores the top screw heads of the first extrusion bolt 11 and the second extrusion bolt 13, which can prevent the bolt screw heads from protruding from the limiting side block 4. The surface of the limiting end block 5 is tightened to prevent the screw head from interfering with the placement and positioning of the workpiece, ensuring that the workpiece can be placed stably on the support table 1. After the limiting end block 4 slides to the appropriate position, the first pressing bolt 11 is tightened. Through the friction between the first pressing bolt 11 and the bottom wall of the first guide groove 2, the limiting end block 4 can be fixed in the current position to prevent it from shifting during the measurement process. After the limiting end block 5 slides to the appropriate position, the second pressing bolt 13 is tightened, and the limiting end block 5 is fixed by the friction between it and the bottom wall of the second guide groove 3.

[0019] The working principle of this utility model is as follows: When in use, the first limiting guide block 6 is slidably set inside the first guide groove 2, and the limiting side block 4 is slid to a suitable position. The first pressing bolt 11 is rotated, and the limiting side block 4 can be fixed in the current position by the friction between the first pressing bolt 11 and the bottom wall of the first guide groove 2, so as to prevent it from being displaced during the measurement process. The second limiting guide block 7 is slidably set in the middle of the second guide groove 3 and the limiting end block 5 is slid to a suitable position. The second extrusion bolt 13 is rotated to fix the limiting end block 5 by using its friction with the bottom wall of the second guide groove 3, so that the second limiting strip 9 and the first limiting strip 8 are located on the opposite side of the limiting end block 5 and the limiting side block 4. The workpiece is placed on the opposite side of the limiting end block 5 and the limiting side block 4, and is limited by the first limiting strip 8 and the second limiting strip 9, which can achieve precise positioning and facilitate measurement. Furthermore, by cooperating with the multiple limiting side blocks 4 and limiting end blocks 5, multiple workpieces can be positioned simultaneously, improving measurement efficiency.
