[0042] The sandblasting assembly of the present application is provided with a cleaning basket 300 matched with the sandblasting fixture 200. The cleaning basket 300 is covered on the top of the sandblasting fixture 200. The loading column 310 is abutted against the urethane positioning column 220, and the product is pushed from the urethane positioning column 220 to the loading column 310 through the unloading plate 230, so as to realize rapid unloading of the product and improve efficiency.

[0043] The sandblasting assembly of the present application is also provided with a pressing plate 400 matched with the sandblasting fixture 200. The pressing plate 400 is used to press the products on each of the urethane foam positioning columns 220 at the same time, so that the products are fastened to the urethane foam positioning columns 220, and the loading is completed quickly; and the fourth through hole 410 of the pressing plate 400 is also provided with a flaring structure, and the inclined surface of the flaring structure is abutted against the product, so that the force applied to the product is more uniform, and the contact area with the product is smaller, thereby reducing the possibility of damage to the product.

[0044] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0045] An embodiment of the present application provides a sandblasting fixture 200, such as Figures 1 to 5 As shown, the sandblasting fixture 200 includes at least but is not limited to:

[0046] A bottom plate 210, wherein the bottom plate 210 is provided with a plurality of first through holes 211;

[0047] A plurality of urethane foam positioning columns 220, each of which comprises a solid material portion 221, a column 222, and a mounting portion 223. The mounting portion 223 is disposed at the bottom end of the column 222, and the mounting portion 223 is mounted in the first through hole 211. The solid material portion 221 is disposed at the upper end of the column 222, and the diameter of the solid material portion 221 gradually decreases from one end connected to the column 222 to the other end. The solid material portion 221 is used to fix the annular product 100 by interference fit;

[0048] The blanking plate 230 is provided with a plurality of second through holes 231 , the positions of the second through holes 231 correspond to the positions of the solid material portion 221 , and the blanking plate 230 is used to slide along the column 222 .

[0049] The use process of the sandblasting jig 200 is as follows: when loading, the annular product 100 is put on the fixed part of the urethane positioning column 220, and the annular product 100 is pressed toward the bottom plate 210 through the pressure plate 400 or other means, so that an interference fit is achieved between the annular product 100 and the fixed part, and the product is fixed; when unloading, the unloading plate 230 is moved away from the bottom plate 210, so that the unloading plate 230 pushes the annular product 100 to the smaller end between the fixed parts, so that the annular product 100 is loosened from the fixed part, and the product is unloaded.

[0050] In this embodiment, by setting the fixing part of the rubber positioning column 220, the elastic deformation of the rubber positioning column 220 is utilized to achieve interference fit with the annular product 100 to complete the clamping of the product. The clamping is simple and convenient. At the same time, the rubber positioning column 220 has a certain elasticity, which can effectively prevent damage to the product and improve the yield rate. By setting the shape of the solid material part 221, the product can be guided when it is sleeved on the rubber positioning column 220, which is convenient for loading. By setting the unloading plate 230, when unloading the product, the product on the rubber positioning column 220 can be pushed down by moving the unloading plate 230 at the same time, so as to realize fast unloading.

[0051] In one embodiment, a limiting ring 224 is provided between the column 222 and the mounting portion 223 of the urethane locating column 220. Figure 2 As shown, the diameter of the limiting ring 224 is larger than the diameter of the column 222 and also larger than the diameter of the mounting portion 223. By setting the limiting ring 224, when each PU positioning column 220 is installed on the base plate 210, the depth of the mounting portion 223 inserted into the first through hole 211 is fixed, thereby ensuring the neatness of the PU positioning column 220. At the same time, the limiting ring 224 can also be used to limit the blanking plate 230 to prevent the blanking plate 230 from fitting against the base plate 210 and affecting the movement of the blanking plate 230.

[0052] In one embodiment, a guide rod 212 is provided on the side of the base plate 210, a third through hole 232 is provided on the side of the blanking plate 230, the guide rod 212 passes through the third through hole 232, and a limit block 213 with an area larger than the third through hole 232 is provided at the top of the guide rod 212.

[0053] like Figure 1 and Figure 3 As shown, four guide rods 212 are provided, and every two guide rods 212 are respectively provided on the two sides of the bottom plate 210, and two third through holes 232 are respectively provided on the corresponding sides of the blanking plate 230, and the positions of the third through holes 232 are aligned with the positions of the guide rods 212. Through the provision of the guide rods 212, the blanking plate 230 is displaced under the action of the guide rods 212, so as to ensure the flatness of the blanking plate 230 during displacement, and avoid incomplete blanking caused by skew; through the restriction of the limit block 213, it can be ensured that the blanking plate 230 will not be excessively displaced during blanking and thus be separated from the urethane positioning column 220.

[0054] In one embodiment, if Figure 4As shown, the guide rod 212 is fixed to the bottom plate 210 through a threaded nut structure; a first groove 214 is provided on the bottom surface of the bottom plate 210 at a position corresponding to the guide rod 212, and the nut is provided in the first groove 214, and the depth of the first groove 214 is greater than the thickness of the nut. The provision of the first groove 214 and the nut prevents the nut from protruding from the bottom surface of the bottom plate 210, thereby ensuring the flatness of the bottom surface of the bottom plate 210.

[0055] In one embodiment, if Figure 4 As shown, the side of the bottom plate 210 is provided with a strip groove 215. The two opposite sides of the bottom plate 210 are respectively provided with strip grooves 215, which have formed a handle to facilitate personnel or a robot to lift or clamp the sandblasting fixture 200.

[0056] Figure 6 Schematic diagram of the structure of the sandblasting assembly provided in one embodiment of the present application. Figure 6 and Figure 7 As shown, the sandblasting components include at least but are not limited to:

[0059] The cleaning basket 300 is used to be disposed above the sandblasting jig 200 with a cover during unloading, and the loading column 310 abuts against the urethane locating column 220 so that the product slides from the urethane locating column 220 to the loading column 310 .

[0060] The working process of the sandblasting jig 200 and the cleaning basket 300 is as follows: after the processing of the annular product 100 fixed on each urethane locating column 220 of the sandblasting jig 200 is completed, the cleaning basket 300 is placed on the top of the sandblasting jig 200, such as Figure 7 As shown, each loading column 310 of the cleaning basket 300 needs to be aligned with each urethane positioning column 220 and abut against each other; the combined cleaning basket 300 and the sandblasting fixture 200 are turned over, and the blanking plate 230 is pushed toward the cleaning basket 300, so that the annular product 100 is loosened from the fixed part under the action of the blanking plate 230 and slides onto the loading column 310 of the cleaning basket 300.

[0061] In the embodiment of the present application, a cleaning basket 300 is provided to match the sandblasting jig 200. The cleaning basket 300 is covered on the top of the sandblasting jig 200. The loading column 310 is abutted against the urethane positioning column 220. The product is pushed from the urethane positioning column 220 to the loading column 310 through the unloading plate 230, so as to realize rapid unloading of the product and improve efficiency.

[0062] In one embodiment, if Figure 2 and Fig.10 As shown, the first end of the loading column 310 is provided with a chamfer, and the first end of the loading column 310 is an end that abuts against the urethane foam positioning column 220, and the top of the solid material portion 221 is provided with a second groove 2211 that matches the shape of the first end of the loading column 310. Through the provision of the chamfer and the second groove 2211, the loading column 310 and the urethane foam positioning column 220 can be quickly aligned under the guidance of the chamfer and the second groove 2211 when they abut, and the loading column 310 and the urethane foam positioning column 220 after abutment are interlocked with each other, and the relative position is stable, thereby avoiding the situation that the loading column 310 and the urethane foam positioning column 220 are not aligned or skewed, resulting in the annular product 100 failing to slide smoothly from the urethane foam positioning column 220 to the loading column 310.

[0063] In one embodiment, the loading column 310 is composed of a cylinder 311 and a side edge 312 disposed on the side wall of the cylinder 311.

The pressing plate 400 is used to press the products on each of the urethane foam positioning columns 220 at the same time, so that the products are fastened to the urethane foam positioning columns 220, and the loading is completed quickly.

[0066] In one embodiment, if Fig. 9As shown, the inner side wall 411 of the fourth through hole 410 is inclined to form a flared structure. The inner side wall 411 of the fourth through hole 410 is inclined to form a C-angle inclined surface to press the R angle of the top of the annular product 100, thereby compacting the annular product 100. The inclined surface of the flared structure abuts against the product, so that the force applied to the product is more uniform, and the contact area with the product is smaller, thereby reducing the possibility of damage to the product.

[0067] An embodiment of the present application further provides a sandblasting device, including: a sandblasting jig 200 as provided in any of the above embodiments; or, a sandblasting assembly as provided in any of the above embodiments.
