Description

Technical Field

[0001] The utility model relates to the technical field of casting clamping, in particular to a clamping tool for processing automobile die castings. Background Art

[0002] Automotive die-castings, particularly aluminum alloy die-castings, offer significant lightweighting advantages. Compared to traditional steel materials, aluminum alloy die-castings significantly reduce the overall weight of a vehicle while maintaining strength. This helps reduce energy consumption, improves fuel efficiency and range, and effectively enhances vehicle performance.

[0003] Die-castings require some post-processing before use, such as spraying, cutting, polishing and other processes. Therefore, they need to be fixed with clamping fixtures. Some die-castings may have uneven end faces. If there is a large height difference at the bottom of the workpiece, resulting in uneven distribution of the center of gravity, it may reduce the stability of the clamping and cause the workpiece to fall off or be damaged during processing. This will not only affect production progress and product quality, but may also pose a threat to the personal safety of operators.

The height positioning block 15 is controlled by rotating the threaded rod 11, so that the clamping height can be fixed, thereby realizing the requirement of clamping workpieces at different heights.

[0023] Threaded rods 11 are provided on both sides of the interior of the guide frame 6 for driving the height positioning block 15 to slide longitudinally. A push-out frame 26 is installed at the bottom end of the guide frame 6. A telescopic component 17 is provided on the outside of the push-out frame 26 and is installed on one side of the horizontal slide 5. A telescopic component 2 13 is provided inside the push-out frame 26 for horizontally pushing out the inclined platform 8. A telescopic component 3 25 is also provided inside the push-out frame 26. The telescopic end of the telescopic component 3 25 passes through and extends to one side of the inclined platform 8. The guide frame 6 and the push-out frame 26 both slide along the length direction of the horizontal slide 5. The telescopic component 1 7 is used to drive the guide frame 6 to move as a whole to reduce the clamping distance. The telescopic component 2 13 is set to drive the inclined platform 8 to move and adjust the extension distance of the upper support base 12. The telescopic component 3 25 is used to lift the height of the upper support base 12 to meet the bottom support requirements.

[0024] A push plate is provided on the side of the tilting platform 8 facing the ejection frame 26. A slide groove 9 is provided on the inclined end surface of the tilting platform 8, allowing the upper support base 12 to slide along the inclined surface. The telescopic assembly 3 25 abuts against the end surface of the upper support base 12, and the top of the upper support base 12 is horizontal.

The top of the horizontal slide 5 is detachably installed with a positioning pin 14 whose end is inserted into the positioning hole 2. Through the setting of the positioning pin 14 and the positioning hole 2, the position of the horizontal slide 5 can be easily fixed, thereby avoiding the situation where the tool falls off due to the shaking of the clamping assembly 10 during the processing process.

[0029] The present invention can support the bottom ends of the die-casting at different heights by setting a plurality of horizontal slides 5, thereby improving the stability of clamping. By sliding the inclined platform 8 along the length direction of the horizontal slide 5 and rotating the horizontal slide 5 along the working platform 1, the support position of the bottom of the die-casting can be adjusted, thereby increasing the contact area between the bottom of the die-casting and the upper support base 12, thereby improving the stability of clamping.
