Detailed Description

This embodiment provides a auto-lock grinding jig, and it mainly includes top board 4, apron 5, anchor clamps board 10 and holding down plate 13, and the cooperation of each part through this auto-lock grinding jig can realize that the auto-lock of product is tight to can also reduce the product that probably leads to in the operation process and bump the fish tail. The respective components are explained below by way of example.

Referring to fig. 1 and 2, the upper press plate 4 and the cover plate 5 are required to be matched with each other in use, and therefore, positioning pins 3 and positioning holes are correspondingly arranged between the upper press plate 4 and the cover plate 5 so as to realize positioning, for example, in one embodiment, the positioning pins 3 are arranged on the upper press plate 4, and the positioning holes are arranged on the cover plate 5 corresponding to the positioning pins 3. Meanwhile, the lower side of the upper pressing plate 4 is provided with a pressing block 1 for pre-pressing the cover plate 5, so that the cover plate 5 can press a product downwards firstly when in use, the product is prevented from tilting due to the extrusion of two sides in the process of being clamped, and preferably, the lower side of the cover plate 5 is provided with a flexible part corresponding to the position of the product, such as a high-strength rubber plate 6, so as to prevent the product from being damaged. Of course, a plurality of second ejection parts matched with the structures on the clamp plate 10 are arranged on the lower side of the upper pressure plate 4. For example, in one embodiment, the ejector pin 2 is provided as a second ejector, and a plurality of through holes are provided in the cover plate 5 corresponding to the second ejector, so that the second ejector can pass through the through holes and then slide blocks 7 on the lower ejector jig plate 10.

As shown in fig. 3, a plurality of pairs of pressing blocks 8 and sliding blocks 7 are arranged on the clamp plate 10, the clamp plate 10 is provided with a material ejecting channel corresponding to the sliding block 7, matching portions 11, such as matching grooves, for matching and connecting products, are arranged on two opposite sides of the outer wall surface of the pressing block group 8, and the sliding block 7 is matched with the middle of the pressing block group 8 through matching surfaces which are tapered from top to bottom. For example, in an embodiment, as shown in fig. 4 and 5, a plurality of product positioning seats 9 are provided on the clamp plate 10, each product positioning seat 9 is provided with the pressing block group 8 and the sliding block 7, each pair of pressing block groups 8 includes two pressing blocks which are arranged oppositely left and right, and a matching portion 11 is provided on the outer side of the two pressing blocks which are arranged oppositely left and right, i.e. on the opposite side, in this embodiment, a plurality of pairs of matching grooves are correspondingly provided on the outer side of the two pressing blocks which are arranged oppositely left and right to fix a plurality of products, a matching hole penetrating through the clamp plate 10 is provided between the two pressing blocks which are arranged oppositely left and right to be used for matching and connecting the sliding block 7, the matching hole has an inner diameter which is tapered from top to bottom, and the sliding block 7 has an outer diameter which is adapted to the inner diameter of the matching hole and is tapered from top to bottom, and the matching hole can be simultaneously used as the material ejecting channel and is used for matching with the lower pressing plate 13. Thereby, after the cooperation through top board 4 and apron 5 realizes the pre-compaction, can push down slider 7 through the second liftout portion of top board 4 for slider 7's lateral wall can promote two briquetting back of the body motion mutually, in order to reach the purpose that compresses tightly the landing leg of product.

In a preferred embodiment, the slider 7 only needs to have a mating end at the top end, the mating end has an outer diameter that tapers from top to bottom, and the outer diameter of the rest of the slider 7 may not change.

Referring to fig. 6, a plurality of first ejecting portions 12 are disposed at positions of the lower pressing plate 13 corresponding to the sliders 7, and are used for being matched with the ejecting channels and ejecting the sliders 7, so that clamping of the product is released. The lower pressing plate 13 is designed to be conveniently detached from the clamp plate 10 after the product is ground, and the sliding block 7 is lifted upwards through the first material ejecting part 12 to enable the pressing block to be loosened and closed, so that the pressing force on the product supporting legs is lost, and the product can be easily detached.

Examples

In this embodiment, the upper platen 4, the cover plate 5, the clamp plate 10 and the lower platen 13 are all circular, and in order to save space and accommodate more products, the clamp plate 10 is provided with a plurality of rows of first product positioning seats 9 arranged in parallel, and the outer sides of two ends of the first product positioning seats 9 are provided with a plurality of rows of second product positioning seats 9 perpendicular to the first product positioning seats 9. The product is a side key of the mobile phone, a left supporting leg and a right supporting leg are arranged on the lower side of the key, and the two supporting legs can be clamped by the matching part 11.

Before the use, the slide block 7 of the self-locking clamp is in a loose state, and the pressing block is also in a loose state at the moment. At the moment, the product is loaded, a cover plate 5 is placed on the clamp plate 10, then the upper pressing plate 4 is pressed downwards to pre-press the cover plate 5 through the pre-pressing block 1, so that the cover plate 5 presses the product downwards firstly, and the product is prevented from tilting due to stress in the clamping process. Then, the upper pressing plate 4 is continuously pressed downwards, so that the first material ejecting part 12 downwards presses the sliding block 7, the sliding block 7 moves downwards under the stress and presses the pressing block to be spread so as to press the left supporting leg and the right supporting leg of the product through the matching part 11 on the outer side, and therefore the product is locked on the clamp plate 10. Then the cover plate 5 is taken down, the sliding block 7 cannot be jacked upwards due to the matching friction force between the sliding block and the pressing block, so that the self-locking purpose is achieved, and the product is fixed on the clamp plate 10 and cannot fall off. After grinding is finished, the sliding block 7 is jacked up through the first jacking portion 12 of the lower pressing plate 13, so that the pressing block is loosened, the pressing force on the product supporting leg is lost, and the product can be easily disassembled.

The above, only for the concrete implementation of this utility model, but the scope of protection of this utility model is not limited to this, and any person skilled in this technical field is in the technical scope of this utility model discloses, according to the technical scheme of this utility model and novel design add in equal replacement or change, all should be covered in the scope of protection of this utility model.
