[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1-3 As shown, a bowl-shaped part positioning and processing device includes:

[0026] Substrate 1, on which a positioning station is provided;

[0027] A positioning mechanism is provided on the positioning station. The positioning mechanism includes a positioning plate 2. The positioning plate 2 is provided with a positioning groove 21 that matches the workpiece 4. A plurality of positioning components 5 are provided around the positioning groove 21. The positioning components 5 abut against the outer edge of the workpiece 4. The positioning components 5 are used to press and position the workpiece 4 on the positioning groove 21.

[0028] The pushing mechanism 6 is disposed on the positioning plate 2. The pushing mechanism 6 and the positioning component 5 are respectively disposed on both sides of the positioning groove 21. The pushing mechanism 6 includes a support block 61. The support block 61 is provided with a support surface 62 that matches the inner sidewall of the workpiece 4. The support block 61 is used to abut and support the inner sidewall of the workpiece 4.

[0029] The positioning plate 2 of this utility model is provided with a positioning groove 21 for loading the workpiece 4. The support surface 62 on the support block 61 abuts against the inner wall of the workpiece 4. The positioning component 5 presses and positions the workpiece 4 in the positioning groove 21. Most of the processing parts can be completed in one clamping of the workpiece 4, while ensuring high positioning accuracy and production efficiency. The support block 61 abuts against the inner wall of the workpiece 4, which greatly reduces the amount of processing deformation.

[0030] In one embodiment of this utility model, a fixing component 3 is provided around the positioning station. The fixing component 3 includes a fixing plate 31, a strip groove 32 is provided on the fixing plate 31, a fixing bolt is provided through the strip groove 32, and a fixing screw hole 34 matching the fixing bolt is provided on the base plate 1. The fixing bolt passes through the strip groove 32 and connects with the fixing screw hole 34 to fix the positioning plate 2 on the base plate 1.

[0031] Specifically, the fixing bolt 33 passes through the strip groove 32 and connects to the fixing screw hole 34 to fix the positioning plate 2 on the base plate 1. This allows for quick positioning of the positioning plate 2, facilitating maintenance and replacement of the positioning plate 2. It is suitable for processing products of various specifications and has a wide range of applications.

[0032] In one embodiment of the present invention, a fixing groove is provided at one end of the fixing plate 31 and a fixing inclined surface 35 is provided at the other end. When the fixing plate 31 fixes the positioning plate 2 on the base plate 1, the fixing groove is engaged on the edge of the positioning plate 2 and the fixing inclined surface 35 abuts against the base plate 1.

[0033] Specifically, when the fixing plate 31 fixes the positioning plate 2 onto the base plate 1, the fixing groove is engaged on the edge of the positioning plate 2, and the fixing inclined surface 35 abuts against the base plate 1. The fixing groove is engaged on the positioning plate 2, which can prevent positional movement during the tightening process of the fixing bolts, ensuring the positional accuracy after tightening. The abutment between the fixing inclined surface 35 and the base plate 1 can increase the contact area between the fixing plate 31 and the base plate 1, ensuring the fixing effect of the positioning plate 2.

[0034] In one embodiment of the present invention, the positioning groove 21 is an annular groove, the width of the annular groove is greater than the edge thickness of the workpiece 4, and the inner diameter of the annular groove is the same as the inner diameter of the workpiece 4, so that the inner edge of the workpiece 4 abuts against the inner wall of the annular groove. An opening 22 is provided on the outer wall of the annular groove, and the opening 22 is used to expose the outer edge of the workpiece 4.

[0035] Specifically, since the inner diameter of the annular groove is the same as the inner diameter of the workpiece 4, the inner edge of the workpiece 4 abuts against the inner wall of the annular groove, which allows for quick positioning of the workpiece 4 and improves processing efficiency. At the same time, the opening 22 is used to expose the outer edge of the workpiece 4, allowing the outer wall of the workpiece 4 to be processed. Most of the processing can be completed in one clamping, thus improving processing efficiency.

[0036] In one embodiment of the present invention, the positioning plate 2 and the base plate 1 are provided with through holes 23, the through holes 23 are located inside the positioning groove 21, and the through holes 23 are connected to the inner cavity of the workpiece 4.

[0037] Specifically, the through hole 23 is located inside the positioning groove 21 and is connected to the inner cavity of the workpiece 4. Since the inner diameter of the annular groove is the same as the inner diameter of the workpiece 4, the inner edge of the workpiece 4 abuts against the inner wall of the annular groove. After processing the workpiece 4, the workpiece 4 may be unable to be removed due to processing or temperature. By blowing air through the through hole 23, the workpiece 4 can be easily separated from the positioning plate 2.

[0038] In one embodiment of the present invention, the positioning plate 2 is provided with a sliding groove that matches the support block 61, the support block 61 is slidably mounted on the sliding groove, the support block 61 is provided with a limiting slot 63 that matches the inner sidewall of the workpiece 4, the support block 61 is drivenly connected to an adjustment component, and the adjustment component is used to adjust the position of the support block 61.

[0039] Specifically, the bowl-shaped workpiece 4 is placed on the positioning plate 2, and the limiting slot 63 on the support block 61 limits the protrusions and other features inside the bowl-shaped workpiece 4, which can quickly position the workpiece 4 and also make the supporting surface 62 on it abut against the inner wall of the workpiece 4, further improving the clamping accuracy of the workpiece 4.

[0040] In one embodiment of the present invention, the adjusting component includes an adjusting block 64, which is fixedly disposed on the positioning plate 2. An adjusting bolt 65 is rotatably disposed on the adjusting block 64, and an adjusting screw hole is provided on the support block 61. The free end of the adjusting bolt 65 is connected to the adjusting screw hole.

[0041] Specifically, rotating the adjusting bolt 65 causes the adjusting screw to rotate on the adjusting screw hole, thereby pushing the support block 61 to slide on the sliding groove to a suitable position. This allows the support block 61 to effectively support the inner wall of the workpiece 4, enabling it to provide uniform support during processing, reducing vibrations during processing, and improving processing accuracy.

[0042] In one embodiment of the present invention, the positioning component 5 includes a pressure plate 51, a waist-shaped groove 54 is provided on the pressure plate 51, a pressure bolt 52 is provided through the waist-shaped groove 54, and a pressure screw hole 53 is provided on the positioning plate 2. The pressure bolt 52 passes through the waist-shaped groove 54 and is connected to the pressure screw hole 53. The pressure plate 51 is used to press and position the workpiece 4 on the positioning groove 21.

[0043] Specifically, rotating the pressure bolt 52 causes the pressure plate 51 to press and position the workpiece 4 on the positioning groove 21, ensuring uniform pressure at each positioning point, reducing other problems caused by stress changes during the processing, and enabling most processing parts to be completed in one clamping while ensuring high positioning accuracy and production efficiency.

[0044] In one embodiment of the present invention, a buffer pad is provided on the pressing end of the pressing plate 51, and an adjusting screw hole is provided on the free end of the pressing plate 51, and an adjusting screw 55 is provided on the adjusting screw hole.

[0045] Specifically, a buffer pad is provided on the pressing end of the pressure plate 51. The pressure plate 51 presses the workpiece 4, effectively ensuring the pressing effect on the workpiece 4, while avoiding scratches on the surface of the workpiece 4 and improving the processing quality of the workpiece 4. An adjusting screw hole is provided on the free end of the pressure plate 51, and an adjusting screw 55 is provided on the adjusting screw hole. The pressing end of the pressure plate 51 abuts against the edge of the workpiece 4, and the end of the adjusting screw 55 on the pressure plate 51 abuts against the positioning plate 2. This not only reduces the movement stroke of the pressure screw, but also changes the pressing posture (contact angle) between the pressing end and the workpiece 4, further ensuring positioning accuracy.

[0046] In one embodiment of this utility model, a spring 56 is sleeved on the pressure screw. One end of the spring 56 is connected to the positioning plate 2, and a retaining ring 57 is provided on the other end. The spring 56 is concentrically arranged with the pressure screw hole 53, and the diameter of the spring 56 is larger than the inner diameter of the pressure screw hole 53. The pressure plate 51 is provided with a plurality of annular grooves that match the retaining ring 57, and the retaining ring 57 is engaged in the annular grooves.

[0047] Specifically, a spring 56 is fitted onto the pressure screw. One end of the spring 56 is connected to the positioning plate 2, and the other end is fitted with a retaining ring 57. Under the reaction force of the spring 56, when the pressure screw is released, the pressure plate 51 can be moved away from the workpiece 4, effectively avoiding interference between the pressure plate 51 and the workpiece 4 during unloading. The diameter of the spring 56 is larger than the inner diameter of the pressure screw hole 53. The retaining ring 57 is engaged in the annular groove, ensuring that after the pressure screw is completely disengaged from the pressure screw hole 53, the pressure plate 51 remains on the positioning plate 2. The workpiece 4 is clamped again. At the same time, the spring 56 has a certain bending property. The pressure plate 51 can be moved away from the workpiece 4 by bending the spring 56 or rotating the pressure plate 51, which makes it easier to unload the workpiece 4. The pressure plate 51 is provided with a number of ring grooves 58 that match the retaining ring 57. The appropriate pressure position can be selected according to the clamping position of different workpieces 4, so that the pressure end of the pressure plate 51 matches the edge of the workpiece 4, which further improves the accuracy of repeated clamping and improves the clamping consistency of each workpiece 4.

[0048] Usage process

[0049] Rotating the adjusting bolt 65 causes the adjusting screw to rotate in the adjusting screw hole, thereby pushing the support block 61 to slide in the sliding groove to a suitable position, placing the bowl-shaped workpiece 4 on the positioning plate 2. Since the inner diameter of the annular groove is the same as the inner diameter of the workpiece 4, the inner edge of the workpiece 4 abuts against the inner wall of the annular groove. At the same time, the limiting slot 63 on the support block 61 limits the protrusions and other features inside the bowl-shaped workpiece 4, and the supporting surface 62 on it abuts against the inner wall of the workpiece 4. Then, the multiple positioning components 5 arranged around the positioning groove 21 lock and fix the workpiece 4 to the positioning plate. 2. Rotate the pressure bolt 52 to tighten it with the pressure screw hole 53, causing the pressure end on the pressure plate 51 to abut against the edge of the workpiece 4. At the same time, the end of the adjusting screw 55 on the pressure plate 51 abuts against the positioning plate 2 until each positioning component 5 fixes the position of the workpiece 4. The contact surface when pressing the bowl-shaped workpiece 4 is small, and the obstruction of the bowl-shaped part is small. Most of the processing parts can be completed in one clamping of the bowl-shaped workpiece 4, while ensuring high positioning accuracy and production efficiency. The support block 61 abuts against the inner wall of the workpiece 4, which greatly reduces the amount of processing deformation.
