Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping fixture for anchor plate machining. Background Technology

[0002] In modern industrial manufacturing, machining equipment, as the core tool for precision machining of various parts, directly impacts the final product quality and production cycle with its machining accuracy and efficiency. During machining, stable workpiece fixation is fundamental to ensuring machining accuracy. Traditionally, this step relied primarily on manual operation by the operator. The operator needed to precisely adjust the workpiece's position on the machine tool table according to its shape, size, and machining requirements, and then secure it firmly using screws, clamps, and other fasteners to prevent workpiece displacement due to vibration, cutting forces, or other factors during machining, which would affect machining accuracy. However, with the accelerated transformation of manufacturing towards automation and intelligence, traditional manual positioning and fastening methods are no longer sufficient to meet the demands of efficient and precise production. Especially in automated production lines for embedded parts, achieving full-process automated control has become crucial for improving production efficiency and reducing labor costs.

[0003] In automated material handling systems, robots are the preferred choice due to their efficiency and flexibility. However, while robots can accurately execute picking and placing actions according to preset programs, they lack the ability to make fine adjustments to workpieces. Specifically, in the processing of embedded anchor plates, due to the wide variety of anchor plate types and sizes, even products from the same batch may have slight dimensional differences. Continuing to use traditional manual positioning methods is not only inefficient but also makes it difficult to guarantee consistency in positioning each time, thus affecting processing accuracy. On the other hand, requiring robots to have the ability to adjust each workpiece individually necessitates the introduction of complex vision recognition systems and high-precision servo drive technology. This undoubtedly increases equipment costs and system complexity significantly, reducing the cost-effectiveness and maintainability of automated production lines. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a machining fixture for anchor plates. This design effectively solves the problems of low efficiency and poor consistency of traditional manual positioning methods, while avoiding the high cost and high complexity caused by individual robot adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes a base, the top surface of which is provided with a positioning reference plane, the positioning reference plane is provided with a reference limiting block, the side of which is provided with a fixed limiting block, the reference limiting block and the fixed limiting block cooperate to form a clamping area with a specific height, a top block is provided below the clamping area, the height of the top block is the same as the specific height of the clamping area, the upper end of the top block is provided with a supporting surface adapted to the shape of the bottom surface of the anchor plate, the lower end of the top block is fixedly connected to the base, a pressing assembly is provided above the clamping area, the pressing assembly includes multiple pressing blocks, the bottom surface of the pressing blocks is provided with a pressing surface matching the contour of the top surface of the anchor plate.

[0006] Preferably, both the reference limiting block and the fixed limiting block have an L-shaped groove at their upper ends. The groove includes a first positioning surface and a second positioning surface that intersect perpendicularly. The first positioning surface is parallel to the positioning reference surface, and the second positioning surface is perpendicular to the positioning reference surface.

[0007] Preferably, the first positioning surface is flush with the top surface of the top block.

[0008] Preferably, the second positioning surface is provided with a wear-resistant alloy layer.

[0009] Preferably, an adjusting pad is provided on the second positioning surface of the reference limiting block, and the side of the adjusting pad is parallel to the second positioning surface.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0024] Please see the appendix Figure 1-6 The anchor plate machining fixture of this embodiment includes a base 1, a positioning reference plane on the top surface of the base 1, a reference limiting block 3 on the positioning reference plane, a fixed limiting block 4 on the side of the reference limiting block 3, the reference limiting block 3 and the fixed limiting block 4 cooperate to form a clamping area with a specific height, a top block 5 is provided below the clamping area, the height of the top block 5 is the same as the specific height of the clamping area, the upper end of the top block 5 is provided with a support surface adapted to the shape of the bottom surface of the anchor plate, the lower end of the top block 5 is fixedly connected to the base 1, a clamping assembly is provided above the clamping area, the clamping assembly includes a plurality of clamping blocks 6, the bottom surface of the clamping block 6 is provided with a pressing surface matching the contour of the top surface of the anchor plate.

[0025] A horizontal sliding stage is installed below the base 1. The sliding stage moves the base 1 to two stopping positions. One position is used for positioning and placing the anchor plate on the base 1, and the other position is used for drilling holes in the anchor plate. The upper end of the base 1 is the positioning reference surface 2. There are two reference limiting blocks 3 on the left rear side of the positioning reference surface 2. The two reference limiting blocks 3 are distributed at a 90-degree angle. The two reference limiting blocks 3 are used for positioning the rear side and left side of the anchor plate. The intersection of the extended lines of the rear side and left side of the anchor plate is the base point of the machining coordinates. This allows for the use of a single set of coordinate points during the processing and handling of anchor plates. Furthermore, for rectangular anchor plates of different specifications, the base point of the processing coordinates remains stable at this single point under the constraint of the two reference limiting blocks 3, thus improving the applicability of the processing fixture. The fixed limiting block 4 is located on the alignment surface of the reference limiting block 3. There are at least two fixed limiting blocks 4, with the two fixed limiting blocks 4 and the two reference limiting blocks 3 distributed along the four sides of the anchor plate. The top cap 9 inside the fixed limiting block 4 exerts a squeezing force on the side edges of the anchor plate. To ensure the anchor plate's side edge is completely flush with the reference limiting block 3, and further, depending on the size of the anchor plate, the number of reference limiting blocks 3 and fixing limiting blocks 4 can be increased on the base 1 to ensure stable support for the anchor plate. The anchor plate is fixed at a certain distance above the base 1, and is supported below by multiple sets of top blocks 5. The staggered distribution of the multiple sets of top blocks 5 can support the anchor plate at a certain height above the base 1, so that even if cutting debris falls onto the base 1 after drilling, it will not affect the anchor plate. For the next step of drilling the anchor plate, raising the fixed height of the anchor plate ensures that the holes can be completely drilled through, guaranteeing the quality and accuracy of the drilling. To further improve the stability of the anchor plate in the clamping area, a clamping assembly is installed above the anchor plate. The clamping block 6 inside the clamping assembly is located above the anchor plate, and the clamping block 6 exerts downward pressure on the anchor plate, making the anchor plate tightly adhere to the top block 5. This prevents the anchor plate from vertically shaking during drilling, ensuring the stability of the anchor plate during drilling.

[0026] Both the reference limiting block 3 and the fixed limiting block 4 have grooves on their inner sides at the upper end. Under the action of the grooves, the reference limiting block 3 and the fixed limiting block 4 will have two additional planes. The one parallel to the positioning reference surface 2 is the first positioning surface 7. The height of the first positioning surface 7 is the same as the height of the top block 5. The first positioning surface 7 is below the anchor plate and plays a positioning and supporting role for the anchor plate. The second positioning surface 8 is perpendicular to the first positioning surface 7 and is used for side limiting of the anchor plate. The surface of the second positioning surface 8 has a wear-resistant alloy layer, which improves the wear resistance of the second positioning surface 8 and ensures that the reference points determined by the two second positioning surfaces 8 will not change after multiple uses, thus ensuring the stability of the reference points and ensuring the accuracy of subsequent drilling.

[0027] An adjusting pad is installed on the side of the second positioning surface 8 on the reference limit block 3. The adjusting pad is used for calibration after the first positioning surface is worn. The adjusting pad is connected to the second positioning surface 8 on the reference limit block 3 by bolts. In contrast, a top cap 9 and a drive assembly 10 are placed horizontally on the second positioning surface 8 on the fixed limit block 4. The drive assembly 10 is a component that can drive the top cap 9 to slide horizontally. The drive assembly 10 can be an electric push rod, a hydraulic push rod, or a pneumatic push rod. The thrust of the top cap 9 on the side of the anchor plate can make the anchor plate closer to the second positioning surface 8 of the reference limit block 3, thereby ensuring the accurate placement of the anchor plate on the reference limit block 3 and the fixed limit block 4.

[0028] The clamping assembly contains a hydraulic cylinder 12 and an adjusting rod 11. The hydraulic cylinder 12 can drive the adjusting rod 11 to rotate and move vertically. The adjusting rod 11 and the clamping block 6 form an inverted L-shaped structure. When fixing the anchor plate, the clamping block 6 is pressed on the surface of the anchor plate. When taking the anchor plate off or on, in order to prevent the clamping block 6 from affecting the movement of the anchor plate, the adjusting rod 11 is raised and rotated by the hydraulic cylinder 12. In this way, the vertical projection of the clamping block 6 will leave the clamping area, which makes it easier to take the anchor plate off or on.

[0029] The clamping block 6 and the adjusting rod 11 are detachably connected by the fixing nut 13, which facilitates the replacement of the clamping block 6 in the future. In addition, the position of the clamping block 6 on the adjusting rod 11 can be changed by the two sets of fixing nuts 13, which can be well applied to anchor plates of different specifications, and can also make the pressing surface of the clamping block 6 fit more closely with the top surface of the anchor plate.

[0030] The top block 5, the fixed limiting block 4, and the clamping assembly are all fixed to the base 1 with screws. When processing different anchor plates, their installation positions can be changed, so that the device can be compatible with different embedded parts products and improve the compatibility of the equipment.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
