Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum casting processing and fixing technology, and in particular to an adaptive fixing device for aluminum casting processing. Background Technology
[0002] The fixing of cast aluminum parts is a crucial step in the casting process, ensuring their stability and accuracy during machining, testing, and assembly. The fixing methods for cast aluminum parts mainly fall into two categories: mechanical fixing and chemical fixing. Mechanical fixing primarily relies on clamping devices, bolt connections, etc., to secure the cast aluminum parts to the machining equipment or workbench. Chemical fixing utilizes adhesives and other chemical materials to bond the cast aluminum parts to other components.
[0003] In the machining of cast aluminum parts, clamping devices are widely used to secure and fix the parts. The irregular shape of cast aluminum parts presents challenges to clamping devices. Traditional clamping devices are often designed to fix workpieces with relatively regular or standard shapes. When faced with cast aluminum parts with varying curvature or shapes, these devices may not be able to effectively adapt and fit tightly against the workpiece surface. This mismatch can lead to insufficient clamping force, causing the workpiece to move or deform during machining, thus affecting machining accuracy and workpiece quality.
[0004] The inability of the clamping device to adapt can also lead to uneven stress on the workpiece. During the clamping process, if the clamping device cannot distribute the clamping force evenly, the cast aluminum part may experience stress concentration due to excessive local pressure. This stress concentration may not only cause workpiece deformation but also lead to defects such as cracks, and in severe cases, even result in the scrapping of the workpiece. Utility Model Content
[0005] The main objective of this invention is to provide an adaptive fixing device for machining cast aluminum parts, which can effectively solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] An adaptive fixing device for machining cast aluminum parts includes an adaptive distance adjustment device. The adaptive distance adjustment device includes an adjustment seat and a slider. The side wall of the adjustment seat has two symmetrical grooves, and a slider is installed in each groove. The inner end of the slider is provided with a gear engagement part. An adjustment plate adapted to the gear engagement part is installed in the seat of the adjustment seat, and a cover is installed at the opening of the adjustment seat. Rotating the adjustment plate causes the slider to slide along the groove, thereby adjusting the slider distance.
[0008] The slider is connected to a first clamping fixing device or a second clamping fixing device via a fixing block. The first clamping fixing device and the second clamping fixing device include a mounting frame and a double-headed telescopic device. The fixing block is connected to the double-headed telescopic device via the mounting frame. The two ends of the double-headed telescopic device are connected to jaws. A connecting frame is connected to the mounting frame and connected to the jaws. A clamping cavity is provided between the two jaws for placing the cast aluminum parts to be processed.
[0009] Among them, the two slide grooves are located on the quadrant points of the adjustment seat, the adjustment seat and the cover are fixed by bolts, the slider and the slide groove are smoothly designed, and the slider and the gear docking part are integrated.
[0010] The slider and the fixed block are fixed by bolts. The fixed block and the mounting frame are designed as an integral part. The mounting frame is connected to the double-headed telescopic device by bolts. The two ends of the double-headed telescopic device are connected to the grippers by bolts. The cross-section of the grippers is arc-shaped.
[0011] The first clamping fixing device and the second clamping fixing device have the same structure, and the mounting frame and the connecting frame are equipped with two sets of clamps.
[0012] The first clamping fixing device and the second clamping fixing device are adjusted in opposite directions. The adjusting seat is rotated to adjust the orientation of the clamping openings of the first clamping fixing device and the second clamping fixing device.
[0013] The inner wall of the gripper is equipped with an anti-slip inner block, and the end face of the anti-slip inner block is connected to an anti-slip pad by an adhesive. The anti-slip inner block and the gripper are connected by a rotating shaft.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The clamping device, with its double-headed telescopic mechanism and gripper design, can firmly hold cast aluminum parts, ensuring stability and safety during machining. The curved design of the grippers adapts to cast aluminum parts of different shapes, improving clamping flexibility and applicability. Meanwhile, the use of anti-slip inner blocks and anti-slip pads increases the friction between the grippers and the cast aluminum parts, effectively preventing slippage during machining and further guaranteeing machining accuracy and quality.
[0016] The adaptive distance adjustment device achieves precise adjustment of the slider distance through the cooperation of the adjustment seat and the slider, thus accommodating cast aluminum parts of different sizes. This adjustment method not only simplifies the operation process and improves work efficiency, but also ensures a uniform distribution of clamping force, avoiding deformation or damage to the cast aluminum parts caused by uneven force. In addition, the smooth design between the groove and the slider reduces friction and improves the smoothness of sliding, making the adjustment process easier and more accurate.
[0017] The combined use of the clamping fixing device and the adaptive distance adjustment device gives the entire device a high degree of versatility and adaptability. The first and second clamping fixing devices have the same structural design and can be used interchangeably, increasing the device's flexibility. At the same time, details such as the bolt fixing of the adjusting seat and the cover, the matching design of the slider and the slide groove, and the rotating shaft connection between the gripper and the anti-slip inner block all improve the structural strength and durability of the device, extending its service life.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figure 1 - Figure 4 As shown, an adaptive fixing device for machining cast aluminum parts includes an adaptive distance adjustment device 1. This device 1 consists of an adjustment seat 11 and a slider 13. The adjustment seat 11 has two symmetrical grooves 12 on its side wall, each groove 12 housing a slider 13. The inner end of the slider 13 is designed with a gear engagement portion 15, while the interior of the adjustment seat 11 houses an adjustment disc 16 adapted to the gear engagement portion 15. To ensure the integrity of the device, a cover 17 is installed at the opening of the adjustment seat 11. By rotating the adjustment disc 16, the slider 13 can slide along the grooves 12, thereby achieving precise adjustment of the slider 13's distance.
[0025] The slider 13 is connected to either the first clamping device 2 or the second clamping device 3 via the fixing block 14. Both clamping devices include a mounting frame 21 and a double-headed telescopic device 22. The fixing block 14 is connected to the double-headed telescopic device 22 via the mounting frame 21, and grippers 23 are connected to both ends of the double-headed telescopic device 22. A connecting frame 24 is connected to the mounting frame 21 and is connected to the grippers 23. A clamping cavity 26 is formed between the two grippers 23 for placing the cast aluminum part to be processed.
[0026] The two slide grooves 12 are located at the quadrant points of the adjusting seat 11, which is fixed to the cover 17 with bolts to ensure the stability of the device. A smooth design is incorporated between the slider 13 and the slide grooves 12 to reduce friction and improve sliding smoothness. The slider 13 and the gear mating part 15 are integrated into a single unit, which improves the structural strength and durability of the device.
[0027] The slider 13 and the fixing block 14 are fixed together with bolts to ensure a strong connection. The fixing block 14 and the mounting bracket 21 are designed as a single unit, which simplifies the structure, reduces the number of parts, and lowers manufacturing costs. The mounting bracket 21 is connected to the double-headed telescopic device 22 with bolts. The two ends of the double-headed telescopic device 22 are connected to the grippers 23 with bolts. The grippers 23 have an arc-shaped cross-section, which can better adapt to cast aluminum parts of different shapes and improve the flexibility and stability of clamping.
[0028] The first clamping fixing device 2 and the second clamping fixing device 3 have the same structural design, which makes them interchangeable in function and increases the versatility of the device. Both the mounting bracket 21 and the connecting bracket 24 are equipped with two sets of grippers 23, which can clamp two cast aluminum parts simultaneously, improving processing efficiency.
[0029] The adjustment directions of the first clamping fixing device 2 and the second clamping fixing device 3 are opposite. Rotating the adjusting seat 11 can simultaneously adjust the orientation of the clamping openings of the first clamping fixing device 2 and the second clamping fixing device 3, so as to adapt to the processing requirements of different directions and improve the adaptability of the device.
[0030] The inner wall of the gripper 23 is fitted with an anti-slip inner block 25. Anti-slip pads are attached to the end faces of the anti-slip inner block 25 via adhesive. This design increases the friction between the gripper 23 and the cast aluminum part, preventing slippage of the cast aluminum part during machining. The anti-slip inner block 25 is connected to the gripper 23 via a rotating shaft, allowing for easy replacement of worn anti-slip inner blocks 25 and improving the maintenance efficiency and service life of the device.
[0031] Insert slider 13 into the groove 12 of adjusting seat 11. Ensure the inner end of slider 13 mates with the gear mating part 15 inside adjusting seat 11. Install cover 17 to close the opening of adjusting seat 11. Secure fixing block 14 to slider 13 with bolts. Connect mounting bracket 21 to the integral part of fixing block 14. Connect double-headed telescopic device 22 to mounting bracket 21. Attach claws 23 to both ends of double-headed telescopic device 22 with bolts. Ensure claws 23 have an arc-shaped cross-section to accommodate different shaped cast aluminum parts. Connect anti-slip inner block 25 to the inner wall of claws 23 via a pivot. Attach anti-slip pads to the end face of anti-slip inner block 25 with adhesive. Attach connecting bracket 24 to mounting bracket 21. Ensure claws 23 on connecting bracket 24 are aligned with claws 23 on mounting bracket 21. Check all bolts and fasteners are secure. Test slider 13 to slide smoothly within groove 12. Test whether the double-headed telescopic device 22 can extend and retract normally. Test whether the gripper 23 can firmly clamp the cast aluminum part.
[0032] Place the cast aluminum part to be processed into the clamping cavity 26. Rotate the adjusting plate 16 to move the slider 13 along the slide groove 12, adjusting the distance of the slider 13 to suit the size of the cast aluminum part. Ensure that the opening of the jaw 23 faces the appropriate direction for processing. By rotating the bolt of the double-headed telescopic device 22, move the jaw 23 inward to clamp the cast aluminum part. Ensure that the anti-slip pad of the jaw 23 is in close contact with the cast aluminum part to prevent slippage. Start the processing equipment and perform the required processing operation on the cast aluminum part. Rotate the bolt of the double-headed telescopic device 22 to move the jaw 23 outward to release the cast aluminum part. Remove the processed cast aluminum part. Regularly check the tightness of the bolts and fasteners. Replace the worn anti-slip inner block 25 to ensure clamping effect. Clean the equipment and maintain its good working condition.
