[0023] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0024] The following is for reference. Figures 1-2 This invention describes a clamping base suitable for fixing workpieces according to an embodiment of the present invention.

[0025] like Figures 1-2As shown, the fixture base includes a main support 1 and two auxiliary supports 2. The main support 1 supports the workpiece, and the two auxiliary supports 2 are respectively arranged on the left and right sides of the main support 1. The auxiliary supports 2 can slide up and down relative to the main support 1 and are fixedly connected to the main support 1 to support and fix the workpiece.

[0026] The fixture base of this embodiment can be applied to workpieces such as rotating bodies, stepped shafts, and end caps. For example, the fixture base is used to fix the rotor end cap, the main bracket 1 is used to support the center position of the rotor end cap, and two auxiliary brackets 2 are used to support the ends of the rotor end cap. Considering irregular rotating bodies, stepped shafts, and end caps, this embodiment allows the auxiliary brackets 2 to slide up and down relative to the main bracket 1. After adjusting the auxiliary brackets 2 to a suitable height position, they are fixedly connected to the main bracket 1. Then, the workpiece is placed on the fixture base and fixed with the auxiliary brackets 2, achieving support and adjustment for different positions of the workpiece. This design can perfectly adapt to workpieces of different shapes and sizes, avoiding the limitations of traditional fixed bases when dealing with non-standard workpieces.

[0027] Both the auxiliary bracket 2 and the main bracket 1 have two opposing inclined surfaces on their upper surfaces, with a horizontal surface between them. In this embodiment, both the auxiliary bracket 2 and the main bracket 1 have a V-shaped groove structure on their upper surfaces. The V-shaped groove can accommodate cylinders of different diameters within a certain range without requiring replacement or adjustment of the support, making it ideal for production lines or experimental environments that process products of various specifications, reducing the need for equipment adjustments. The two opposing inclined surfaces and the horizontal surface in the V-shaped groove structure can support and position the outer circumference of the workpiece, such as the rotor end cover, preventing the workpiece from rolling back and forth. Compared to the arc-shaped groove structure design, it has greater versatility and better stability. Therefore, the upper surfaces of both the auxiliary bracket 2 and the main bracket 1 are designed with a V-shaped groove structure. This design can perfectly fit the shape of the rotating body, ensuring the stability of the workpiece during clamping and measurement. This innovative design not only significantly improves the clamping accuracy but also effectively reduces errors caused by irregular workpiece shapes. Therefore, it greatly improves the processing efficiency and product quality of the entire production line.

[0028] Therefore, the base fixture in this embodiment has an extremely simple and compact structure, which not only facilitates operation and maintenance but also achieves extremely high precision during clamping, ensuring the accuracy of workpiece positioning. Furthermore, the sub-support 2 can be steplessly adjusted in height, making workpiece placement more stable. At the same time, this design, through a flexible adjustment mechanism, perfectly adapts to workpieces of different shapes and sizes, avoiding the limitations of traditional fixed bases when dealing with non-standard workpieces. This not only reduces the need to change to different base models and lowers production costs but also significantly improves the flexibility and adaptability of the production line.

[0029] Furthermore, the main bracket 1 is provided with a first sliding part 11 on both sides, and the sub-bracket 2 is provided with a second sliding part 21 on the side facing the main bracket 1, which slides in cooperation with the first sliding part 11. One of the first sliding part 11 and the second sliding part 21 is a groove, and the other of the first sliding part 11 and the second sliding part 21 is a protrusion.

[0030] In this embodiment, such as Figure 1 As shown, the main bracket 1 has sliding grooves on both sides, and the sub-bracket 2 has a protrusion on the side facing the main bracket 1. Through the sliding cooperation between the sliding groove and the protrusion between the sub-bracket 2 and the main bracket 1, the operator can make high-precision free adjustments to the sub-bracket 2 to adapt to workpieces of various shapes and sizes.

[0031] Specifically, a sliding groove is provided in the middle of each side of the main bracket 1, and the sliding groove extends in the vertical direction. A corresponding protrusion is provided in the middle of the side of the sub-bracket 2 facing the main bracket 1, so that the sub-bracket 2 can move upward or downward as a whole, and avoid the sub-bracket 2 from shifting when sliding up and down.

[0032] Furthermore, each end of the main bracket 1 is provided with a plurality of locking holes 12 arranged in the vertical direction, and each end of the sub-bracket 2 facing the main bracket 1 is provided with through holes 22. The fixture base also includes a locking member 3, which passes through the through hole 22 and selectively locks and fixes itself to any one of the locking holes 12.

[0033] In this embodiment, each end of the main bracket 1 is provided with multiple locking holes 12. After the sub-bracket 2 slides to a suitable position relative to the main bracket 1 in the vertical direction, the locking member 3 passes through the through hole 22 of the sub-bracket 2 and locks into the corresponding locking hole 12, thus firmly locking the sub-bracket 2 to both sides of the main bracket 1, making the structure of the fixture base in this embodiment more stable. Furthermore, by designing multiple locking holes 12 arranged sequentially in the vertical direction, stepless adjustment of the fitting height is achieved, which can adapt to workpieces of different shapes and sizes. The locking member 3, as a key connecting component, ensures the stability of the sub-bracket 2 after adjustment and effectively prevents workpiece displacement during processing.

[0034] Furthermore, the fixture base also includes a lifting rod 4, which is supported at the lower end of the sub-support 2. In this embodiment, the height of the sub-support 2 in the vertical direction can be quickly adjusted by the lifting rod 4, enabling this embodiment to adapt to workpieces of different sizes, such as rotor end caps, further improving the flexibility and adaptability of clamping.

[0035] Specifically, the lifting rod 4 is supported at the middle of the lower end of the sub-support 2, ensuring the stability of the sub-support 2 during adjustment. In one embodiment, the lifting rod 4 includes a sleeve seat and a movable rod. The top end of the movable rod is connected to the sub-support 2, and the lower end of the movable rod is movably disposed within the sleeve seat and protrudes from the sleeve seat. An elastic element is provided within the sleeve seat for connecting the movable rod. The elastic element prevents the movable rod from detaching from the sleeve seat and provides support and cushioning for the movable rod. Specifically, when the movable rod moves upward, the elastic element is stretched; when the movable rod moves downward, the elastic element is compressed, which controls the upper and lower limits of the movable rod, thereby allowing the height of the sub-support 2 to be adjusted as needed, ensuring that the movable rod moves up and down within a certain height range. In another embodiment, the lifting rod 4 is a telescopic rod, and the height of the sub-support 2 is adjusted by adjusting the telescopic rod.

[0036] Furthermore, the sub-support 2 can slide relative to the main support 1 until the upper surface of the sub-support 2 and the upper surface of the main support 1 are aligned with each other. That is, the sub-support 2 can slide so that the V-shaped groove on the upper surface of the sub-support 2 is aligned with the V-shaped groove on the upper surface of the main support 1, which is applicable to cylindrical rotating bodies, end caps and other workpieces.

[0037] Furthermore, the fixture base also includes a fixing frame 5, which is fixed to the side of the sub-support 2 opposite to the main support 1, and a portion of the fixing frame 5 protrudes above the sub-support 2. The fixing frame 5 is used to fix the workpiece. With this configuration, the fixing frame 5 is fixed on the sub-support 2 to fix the workpiece and prevent it from rotating or moving during processing, thereby ensuring processing accuracy and product quality.

[0038] Furthermore, the fixture 5 is provided with a second fixing hole and a third fixing hole, with the second fixing hole located above the third fixing hole. The second fixing hole is used to fix the workpiece. The fixture base also includes a first fastener 6, which passes through the third fixing hole and is fixedly connected to the sub-support 2. With this configuration, the first fastener 6 passes through the third fixing hole of the fixture and is connected to the sub-support 2, thereby ensuring that the fixture 5 is stably fixed on the sub-support 2. When the workpiece is placed on the fixture base, it can be fixed by the first fastener 6 passing through the second fixing hole, preventing it from flipping or moving.

[0039] Furthermore, the fixture base also includes a base plate 7, on which the main bracket 1 is mounted. The base plate 7 has fourth fixing holes at its four corners for fixed connection to the worktable. With this configuration, the base plate 7 serves as the supporting foundation for the entire device. The second fastener 8 passes through the fourth fixing holes, firmly fixing the base plate 7 to the worktable, ensuring the stability and accuracy of the entire device.

[0040] Furthermore, the dimension of the sub-support 2 in the vertical direction is smaller than that of the main support 1 in the vertical direction; and / or, the dimension of the sub-support 2 in the horizontal direction is smaller than that of the main support 1 in the horizontal direction. With this configuration, the volume of the main support 1 is larger than that of the sub-support 2, so that the main support 1, as the key component that mainly supports the workpiece, can adjust the support height of the workpiece end by moving the sub-support 2 up and down, thereby ensuring the clamping stability of the workpiece.

[0041] Therefore, the fixture base of this embodiment ensures close cooperation and efficient operation between various components, which not only improves the accuracy of measurement, but also ensures the stability of the clamping process, thereby significantly improving the efficiency of the entire production process and the quality of the product. At the same time, it also significantly reduces the difficulty of operation and maintenance costs, making the fixture base of this embodiment have broad application prospects in industrial production.
