Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for processing exfoliated corrosion samples, and specifically to an auxiliary device for processing exfoliated corrosion samples. Background Technology

[0002] The exfoliation corrosion test is an important test for evaluating the exfoliation corrosion resistance of aluminum alloys. Before conducting the exfoliation corrosion test, it is necessary to use processing equipment such as sawing machines and milling machines to process the sample into the dimensions required by the test standard. For aluminum alloys, it is also necessary to drill holes in the sample. Before processing, it is necessary to use vises and auxiliary devices to limit the position of the sample.

[0003] Chinese Patent Publication No. CN219805721U discloses an auxiliary device for processing exfoliation corrosion samples, comprising: a support body; a sample placement part for placing the sample to be processed, the sample placement part being located on one side of the support body and extending inward, the sample placement part having a third flat placement surface; and a tension adjustment mechanism disposed on the support body, the tension adjustment mechanism being disposed relative to the third placement surface of the sample placement part and capable of extending into the sample placement part to clamp the sample located within the sample placement part. This auxiliary device for processing exfoliation corrosion samples requires only two sample loading and unloading operations from milling the side surface to completing drilling, and can drill multiple samples simultaneously. It is simple to operate, convenient for sample loading and unloading, and the sample processing quality and dimensions meet standard requirements. It has high work efficiency and is particularly suitable for processing large batches of samples.

[0004] In the existing technology, after processing one side of the sample, the pressure screw needs to be rotated again to release the sample from the limit position, and then the sample is taken out and moved to a different position. This increases the complexity of the work and requires workers to further align multiple samples, which increases labor intensity and reduces work efficiency. Utility Model Content

[0005] This invention provides an auxiliary device for processing peeling corrosion samples, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides an auxiliary device for processing exfoliated corrosion samples, comprising:

[0008] Auxiliary frame;

[0009] The pressure screw is threaded onto the surface of the auxiliary frame and is used to limit and press the aluminum alloy sample.

[0010] Clamping bars are fixedly connected to the lower surface of the auxiliary frame to help the auxiliary frame and vise be assembled together;

[0011] A rotating device is installed on the surface of the auxiliary frame to facilitate processing by helping the aluminum alloy sample to rotate at an angle.

[0012] The limiting device is installed on the side wall of the auxiliary frame. By adjusting the distance between the two limiting blocks, the sample can be quickly centered.

[0013] Furthermore, the rotating device includes a slide rail, which is fixedly connected to the inner wall of the auxiliary frame. A slide plate is slidably connected to the inner wall of the slide rail, and a disc is fixedly connected to the surface of the slide plate. A turntable is rotatably connected to the upper surface of the disc.

[0014] With the above technical solution, when it is necessary to adjust the side of the sample processing, the counter-pressure screw is rotated in the opposite direction, and then the slide is pulled outward to move the disc and turntable out of the auxiliary frame. Further rotation of the turntable can achieve rapid adjustment of the side of the sample.

[0015] Furthermore, two connecting blocks are fixedly connected to the surface of the auxiliary frame, both of which are U-shaped, and pressing blocks are fixedly connected to both sides of the slide plate, the pressing blocks being made of rubber.

[0016] With the above technical solution, the pressure block will abut against the inner wall of the connecting block when the slide plate slides inward towards the inner rail, thereby achieving a limit and further preventing the slide plate from moving during the processing.

[0017] Furthermore, an extension plate is fixedly connected to the surface of the skateboard, and a plug rod is slidably connected to the surface of the extension plate. The surface of the turntable has four circular grooves, and the dimensions of the four circular grooves are all adapted to the dimensions of one end of the plug rod.

[0018] The above technical solution enables rapid adjustment of the turntable angle by inserting the insert rod into the circular groove at a fixed position, eliminating the need for further observation of the sample placement angle.

[0019] Furthermore, a spring is fitted onto the surface of the insertion rod, and the two ends of the spring are fixedly connected to the insertion rod and the extension plate, respectively.

[0020] With the above technical solution, the spring drives the insertion rod to be stably inserted into the circular groove, and it will not come out.

[0021] Furthermore, the limiting device includes a bidirectional screw, which is rotatably connected to the auxiliary frame. Two limiting blocks are threadedly connected to the surface of the bidirectional screw. The cross-section of the two limiting blocks is trapezoidal. Push blocks are slidably connected to the surface of the two limiting blocks. The surface of the push blocks is chamfered and is L-shaped.

[0022] Through the above technical solution, rotating the bidirectional screw can adjust the limiting block to a position that matches the length of the sample. After the rotating device adjusts the angle, the sample moves inward and then abuts against the surface of the limiting block. Through its shape design, multiple samples can be quickly aligned.

[0023] Furthermore, the surface of the push block is rotatably connected to three rollers.

[0024] With the above technical solution, when the pusher moves upward to push the sample, the roller contacts the sample, reducing the friction between the two and making it easier for the pusher to pull upward.

[0025] Furthermore, a limiting rod is fixedly connected to the surface of the auxiliary frame, and both limiting blocks are slidably connected to the limiting rod.

[0026] Through the above technical solution, the limiting rod can restrict the limiting block, so that the limiting block will not rotate when the bidirectional screw rotates.

[0027] The above-described solution of this utility model has at least the following beneficial effects:

[0028] 1. This utility model, by setting a rotating device, can quickly adjust the side of the sample after processing one side of the sample, without having to take the sample out of the auxiliary frame and place it again, thus speeding up the adjustment process as much as possible, making the replacement process more convenient, and further improving work efficiency.

[0029] 2. This utility model, by setting a limiting device, can cooperate with the rotating device to quickly align multiple samples after the side of the sample is adjusted. This allows the samples to be directly processed after moving into the auxiliary frame, reducing the adjustment steps for the samples and thus speeding up the processing efficiency.

Detailed Implementation

[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figures 1 to 4 As shown, an embodiment of this utility model provides an auxiliary device for processing exfoliated corrosion samples, comprising:

[0038] Auxiliary frame 1; pressing screw 2, threadedly connected to the surface of auxiliary frame 1, used to limit and press the aluminum alloy sample; clamping strip 3, fixedly connected to the lower surface of auxiliary frame 1, used to help auxiliary frame 1 combine with vise; rotating device 4, set on the surface of auxiliary frame 1, to facilitate processing by helping the aluminum alloy sample to rotate at an angle; limiting device 5, set on the side wall of auxiliary frame 1, to facilitate quick centering of the sample by adjusting the distance between the two limiting blocks 52.

[0039] like Figures 1 to 3As shown, the rotating device 4 includes a slide rail 401, which is fixedly connected to the inner wall of the auxiliary frame 1. A slide plate 402 is slidably connected to the inner wall of the slide rail 401. A disc 403 is fixedly connected to the surface of the slide plate 402, and a turntable 406 is rotatably connected to the upper surface of the disc 403. When it is necessary to adjust the side of the sample processing, the counter-rotating screw 2 is rotated in the opposite direction, and then the slide plate 402 is pulled outward, which can move the disc 403 and the turntable 406 out of the auxiliary frame 1. Further rotation of the turntable 406 can realize the rapid adjustment of the side of the sample. Two connecting blocks 404 are fixedly connected to the surface of the auxiliary frame 1. Both connecting blocks 404 are U-shaped. A pressing block 405 is fixedly connected to both sides of the slide plate 402. The pressing block 405 is made of rubber. The pressing block 405 slides the slide plate 402 inward towards the slide rail 401. When moving, it will abut against the inner wall of the connecting block 404, thereby achieving a limit and further preventing the slide plate 402 from moving during processing. An extension plate 408 is fixedly connected to the surface of the slide plate 402, and an insertion rod 409 is slidably connected to the surface of the extension plate 408. The surface of the turntable 406 has four circular grooves 407, and the size of the four circular grooves 407 is adapted to the size of one end of the insertion rod 409. By inserting the insertion rod 409 into the circular groove 407 at a fixed position, the angle of the turntable 406 can be quickly adjusted without further observation of the angle of the sample placement. A spring 410 is sleeved on the surface of the insertion rod 409. The two ends of the spring 410 are fixedly connected to the insertion rod 409 and the extension plate 408 respectively. The spring 410 drives the insertion rod 409 to be stably inserted into the circular groove 407 without detaching.

[0040] In this embodiment of the utility model (working principle), the sample is placed on the turntable 406. When adjusting the side, the pressure screw 2 is rotated upwards, and the sample is disengaged from the limit position. The slide plate 402 drives the disc 403 and the turntable 406 to be pulled outwards until they can rotate. The insertion rod 409 is further pulled, causing the insertion rod 409 to disengage from the circular groove 407. Then the sample rotates to the position to be processed. At this time, the insertion rod 409 will be tightly inserted into the circular groove 407 by the spring 410 to limit the turntable 406. At this time, the angle of the sample is adjusted. The slide plate 402 is pushed inwards, and the pressure block 405 will press against the inside of the connecting block 404 to limit the slide plate 402. At this time, the slide plate 402 will no longer slide, and the operator can process the sample.

[0041] like Figure 1 and Figure 4As shown, the limiting device 5 includes a bidirectional screw 51, which is rotatably connected to the auxiliary frame 1. Two limiting blocks 52 are threadedly connected to the surface of the bidirectional screw 51. The cross-section of each limiting block 52 is trapezoidal, and a push block 53 is slidably connected to the surface of each limiting block 52. The surface of the push block 53 has a chamfered surface and is L-shaped. Rotating the bidirectional screw 51 adjusts the limiting blocks 52 to a position suitable for the sample length. After the rotating device 4 adjusts the angle, the sample moves inward and abuts against the limiting blocks. The surface of block 52, through its shape design, can quickly align multiple samples. The surface of push block 53 is rotatably connected with three rollers 54. When push block 53 moves upward to push the sample, rollers 54 contact the sample, reducing the friction between them and facilitating the upward pulling of push block 53. The surface of auxiliary frame 1 is fixedly connected with limit rods 55. Both limit blocks 52 are slidably connected to limit rods 55. Limit rods 55 can restrict limit blocks 52, so that limit blocks 52 will not rotate when bidirectional screw 51 rotates.

[0042] In this embodiment of the invention, when the sample is placed, the bidirectional screw 51 is rotated to adjust the two limiting blocks 52 to a position that matches the side of the sample. Furthermore, when the sample adjustment angle is returned, the inclined surface of the limiting block 52 can achieve alignment. If the sample in the higher area is offset due to rotation and movement, the push block 53 can be pulled upward. Through the cooperation of the chamfered surface of the push block 53 and the surface roller 54, the upper sample can be aligned with the lower sample, so that no error occurs during the simultaneous processing of multiple samples.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
