Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy parts processing, and in particular to a pressure-proof cover plate structure and a positioning processing device. Background Art

[0002] The shell of electronic products can be made of aluminum alloy, which has the characteristics of high strength, good corrosion resistance and long service life. Aluminum alloy needs to be processed into thin-walled parts first, and then the thin-walled parts of aluminum alloy are milled and drilled by CNC machine tools.

[0003] After CNC machine processing, thin-walled parts need to be painted to change their appearance. Therefore, thin-walled parts have higher requirements for surface flatness. When a chuck-type fixture is used to clamp thin-walled parts, the chuck-type fixture is easy to scratch the surface of the thin-walled parts, which reduces the processing quality of the thin-walled parts.

[0004] For example, the technical solution disclosed in the comparative document CN201721641125.8 discloses a die-cast aluminum alloy motor housing processing fixture, including a chuck, a mounting plate connected to the chuck via a plurality of support seats, a plurality of auxiliary limit cylinders equidistantly spaced circumferentially distributed on the surface of the mounting plate, the auxiliary limit cylinders are controlled by an electromagnetic valve, the auxiliary limit cylinders are connected to the mounting plate via a cylinder mounting seat, and three clamping claws equidistantly spaced circumferentially distributed on the surface of the chuck body. The die-cast aluminum alloy motor housing processing fixture is easy to use and quick to install, and no shaking occurs during the processing. When it is necessary to clamp thin-walled parts for processing, since the die-cast aluminum alloy motor housing processing fixture clamps the side wall of the thin-walled part through the clamping claws, when the force of the clamping claws abutting against the thin-walled part is too large, the clamping claws are likely to scratch the surface of the thin-walled part.

The bottom plate 210 is embedded in the mounting groove 101, so that the bottom plate 210 is not easy to shake. A first arc groove 2101 is provided on the side of the bottom plate 210 away from the mounting base 100. The bottom plate 210 is also provided with a connecting hole 2102 and a second telescopic through hole 2103. The fixing member 230 is sequentially penetrated in the connecting groove 101. The elastic cover plate 220 is provided with a second arc groove 2201 on one side adjacent to the first arc groove 2101, the first arc groove 2101 and the second arc groove 2201 are adapted to the arc surface of the processed part, the elastic cover plate 220 is covered on the bottom plate 210, the elastic cover plate 220 is provided with a third telescopic through hole 2202 and a processed through hole 2203, and the processed through hole 2203 is connected to the second arc groove 2201;

[0034] In this embodiment, when processing thin-walled parts, the lifting cylinder 420 moves the positioning plate 410 upward, so that the bottom of the positioning block 411 moves to the same height as the first arc groove 2101, and the thin-walled part is placed on the first arc groove 2101, and one end of the thin-walled part is abutted against the positioning block 411, so that the thin-walled part is fixed in the position of the first arc groove 2101, and then the elastic cover plate 220 is driven down by the contraction of the telescopic component 300, and the second arc groove 2201 of the elastic cover plate 220 abuts against the thin-walled part. The contact surface of the elastic cover plate 220 abutting against one side of the thin-walled part is elastic, and the thin-walled part is clamped between the first arc groove 2101 and the second arc groove 2201. The part of the side wall of the thin-walled part that needs to be processed is located in the processing hole 2203, and then the drill is controlled by the CNC machine tool to extend into the processing hole 2203 to process the thin-walled part.

[0035] In the above-mentioned compression-free cover plate structure 10, a thin-walled part is placed in the first arc groove 2101, and one end of the thin-walled part is abutted against the positioning block 411, so that the position of the thin-walled part on the first arc groove 2101 is fixed, so that the position of the thin-walled part processed by the CNC machine tool is accurate, thereby improving the processing accuracy; the thin-walled part is clamped between the first arc groove 2101 and the second arc groove 2201 by the bottom plate 210 and the elastic cover plate 220, the contact surface of the thin-walled part and the bottom plate 210 and the elastic cover plate 220 are adapted, and the side of the elastic cover plate 220 abutting against the thin-walled part is elastic, which avoids scratches on the surface of the thin-walled part, thereby improving the processing quality of the thin-walled part.

[0036] like Figure 3 and Figure 5 As shown, in one embodiment, the elastic cover plate 220 also includes a cover plate body 221 and a silicone layer 222, the cover plate body 221 is provided with a first locking channel 2204 and a first processing channel 2205, the silicone layer 222 is provided with a second locking channel 2206 and a second processing channel 2207, the silicone layer 222 covers a side of the elastic cover plate 220 adjacent to the bottom plate 210, the first locking channel 2204 is connected to the second locking channel 2206 to form a third telescopic through hole 2202, the telescopic end of the telescopic component 300 is sequentially penetrated through the second locking channel 2206 and the second processing channel 2207, the telescopic end of the telescopic component 300 abuts against the side of the cover plate body 221 away from the silicone layer 222, the first processing channel 2205 is connected to the second processing channel 2207 to form a processing through hole 2203. In this embodiment, the cover body 221 is made of steel, so that the cover body 221 is not easily damaged. The thin-walled parts are clamped between the base plate 210 and the silicone layer 222. The silicone layer 222 is soft in texture, which prevents the thin-walled parts from being scratched by the elastic cover 220. The silicone layer 222 can be deformed and fit tightly with the thin-walled parts, so that the friction between the silicone layer 222 and the thin-walled parts is increased, and the thin-walled parts are more stable when clamped.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, the number of telescopic components 300 is multiple, and the number of the first telescopic through hole 103, the second telescopic through hole 2103, the second telescopic lock hole and the third telescopic through hole 2202 is multiple. In this embodiment, the multiple telescopic components 300 are spaced at the same distance, and the multiple telescopic components 300 abut against the elastic cover plate 220 when they are contracted, so that the elastic cover plate 220 is evenly abutted against the thin-walled parts, thereby implementing a more stable clamping of the thin-walled parts between the elastic cover plate 220 and the bottom plate 210.

[0038] like Figure 2 As shown, in one embodiment, the telescopic assembly 300 includes a telescopic cylinder 310 and a telescopic rod 320, one end of the telescopic rod 320 is connected to the telescopic end of the telescopic cylinder 310, the telescopic rod 320 is sequentially inserted into the first telescopic through hole 103, the second telescopic through hole 2103 and the third telescopic through hole 2202, and the other end of the telescopic rod 320 is abutted against the elastic cover plate 220. In this embodiment, the telescopic cylinder 310 is connected to an air source, and the telescopic cylinder 310 is controlled by controlling the air source to extend and retract to drive the telescopic rod 320 to extend and retract, so that the thin-walled parts between the bottom plate 210 and the elastic cover plate 220 are quickly loosened and clamped, so that the thin-walled parts can be quickly replaced for processing.

[0039] like Figure 1 As shown, in one embodiment, there are multiple processed holes 2203, first arc grooves 2101 and second arc grooves 2201. In this embodiment, multiple thin-walled parts can be mounted on the corresponding first arc grooves 2101 and clamped, and then the thin-walled parts corresponding to the processed holes 2203 can be sequentially passed through by a CNC machine tool, thereby accelerating the processing efficiency of the thin-walled parts.

[0040] like Figure 1 As shown, in one embodiment, a plurality of first arc grooves 2101 are arranged in parallel on the bottom plate 210, and a plurality of second arc grooves 2201 are arranged in parallel on the elastic cover plate 220. In this embodiment, the plurality of first arc grooves 2101 are arranged in parallel, so that the thin-walled parts installed on the first arc grooves 2101 are parallel, so that the positions of the thin-walled parts to be processed are parallel, and the CNC machine tool only needs to move in parallel to process different thin-walled parts, thereby improving the processing speed of the thin-walled parts.

[0041] like Figure 1 and Figure 4As shown, in one embodiment, the number of the mounting holes 102 and the connecting holes 2102 is multiple. In this embodiment, multiple fixing members 230 fix the bottom plate 210 on the mounting base 100, so that the connection strength between the bottom plate 210 and the mounting base 100 is improved, and the drill bit of the CNC machine tool is not easy to affect the bottom plate 210 during processing, so that the parts placed in the first arc groove 2101 are more stable.

[0042] like Figure 1 As shown, in one embodiment, the lifting assembly 400 further includes a guide member 430, the lifting cylinder 420 is provided with a guide groove 4201, one end of the guide member 430 is connected to the positioning plate 410, and the other end of the guide member 430 is passed through the guide groove 4201. In this embodiment, the guide member 430 slides along the extension direction of the guide groove 4201, and the guide member 430 guides the positioning plate 410, thereby reducing the shaking generated when the positioning plate 410 moves.

[0043] like Figure 1 As shown, in one embodiment, the number of guide members 430 and guide grooves 4201 is two, and the two guide grooves 4201 are arranged on both sides of the telescopic end of the lifting cylinder 420, and one end of each guide member 430 is connected to the positioning plate 410, and the other end of each guide member 430 is inserted into the corresponding guide groove 4201.

[0044] A positioning processing device includes the non-pressing cover plate structure 10 of any of the above embodiments. In this embodiment, the thin-walled part is clamped between the first arc groove 2101 and the second arc groove 2201 by the elasticity of one end surface of the elastic cover plate 220, thereby preventing the surface of the thin-walled part from being clamped by the clamping plate assembly 200, thereby improving the processing quality of the thin-walled part.

[0045] Compared with the prior art, the present invention has at least the following advantages:

[0046] 1. The above-mentioned pressure-free cover plate structure 10 and positioning processing device, the thin-walled part is placed in the first arc groove 2101, and one end of the thin-walled part is abutted against the positioning block 411, so that the position of the thin-walled part on the first arc groove 2101 is fixed, so that the position of the thin-walled part processed by the CNC machine tool is accurate, thereby improving the processing accuracy;

[0047] 2. The thin-walled part is clamped between the first arc groove 2101 and the second arc groove 2201 by the bottom plate 210 and the elastic cover plate 220. The contact surfaces of the thin-walled part and the bottom plate 210 and the elastic cover plate 220 are adapted to each other, and the side of the elastic cover plate 220 abutting against the thin-walled part is elastic, which avoids scratches on the surface of the thin-walled part, thereby improving the processing quality of the thin-walled part.

[0048] The above embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
