[0028] Example 1

[0029] A machining workpiece positioning fixture is provided, please refer to Figure 1 , including a processing platform 10, which is located on mechanical processing equipment such as a milling machine, a lathe, a drilling machine and a sawing machine.

[0030] See also Figure 1 A plurality of through slots 11 are provided on the processing platform 10, and the through slots 11 are used to discharge processing debris.

[0031] See also Figure 1 , Figure 2 The pad 20 is rotatably connected to the processing platform 10, and the pad 20 is used to carry the workpiece. That is, after the workpiece is placed on the pad 20, the position of the workpiece can be adjusted by rotating the pad 20, without the need to move the workpiece back and forth multiple times. Preferably, a blocking edge 22 is provided on the pad 20 to block the workpiece.

[0032] See also Figure 1 , Figure 2 A handle 23 is provided on the outer ring of the pad 20, and the pad 20 can be easily rotated by the provided handle 23, thereby further improving the convenience of operation.

[0033] See also Figure 1 , Figure 3 The crimping assembly 30 includes a plurality of vertical rods 31 fixedly connected to the processing platform 10, and abutment plates 32 are movably provided on the plurality of vertical rods 31, and a limiting sleeve 33 is screwed on each set of vertical rods 31, and the limiting sleeve 33 can be rotated downward to push the abutment plate 32 to abut against the edge of the workpiece.

[0034] See also Figure 1 , Figure 3 A plurality of vertical rods 31 are located outside the pad 20. After the position of the workpiece is adjusted, the edge of the workpiece is close to the side of the abutment plate 32. By rotating the limit sleeve 33 downward, the limit sleeve 33 pushes the abutment plate 32 downward to abut the edge of the workpiece, thereby preliminarily fixing the workpiece.

[0035] See also Figure 1 , Figure 3 The chain 40 is connected to the abutment plate 32 through a pulling assembly 50. The chain 40 is wound into a receiving circle above the pad 20. The pulling assembly 50 can drive the chain 40 to tighten the receiving circle and lock the workpiece; the pulling assembly 50 includes an electric cylinder body 53 and a plurality of first ring bodies 51 and a plurality of second ring bodies 52 arranged on the abutment plate 32. One end of the chain 40 passes through the plurality of first ring bodies 51 and is connected to the movable end of the electric cylinder body 53, and the other end of the chain 40 passes through the plurality of second ring bodies 52 and is connected to the movable end of the electric cylinder body 53.

[0036] As the abutment plate 32 abuts against the edge of the workpiece, the receiving ring follows the abutment plate 32 and is sleeved on the workpiece. Then, the movable rod of the electric cylinder body 53 is extended to drive the two ends of the chain 40 to move, so that the two sides of the formed receiving ring move along the multiple first ring bodies 51 and the multiple second ring bodies 52 respectively, and then the receiving ring is tightened. After the receiving ring is tightened, the chain 40 contacts the workpiece to play a locking role, thereby completing the positioning of the workpiece.

[0037] When the positioning is canceled, the movable rod of the electric cylinder body 53 contracts, the receiving ring relaxes the chain 40 and no longer locks the workpiece, and then the limiting sleeve 33 is rotated upward, so that the abutment plate 32 loses the precise abutment with the edge of the workpiece.

[0038] After the workpiece is initially abutted and fixed by the abutment plate 32, the workpiece is locked by moving the locking chain 40, thereby positioning the workpiece on the processing platform 10, which can achieve the positioning effect on workpieces of different shapes. The operation is simple when processing and canceling the positioning after positioning the workpiece, and there is no need to operate separately from multiple different directions, thereby improving the processing efficiency of the workpiece.

[0039] Example 2

[0040] A machining workpiece positioning fixture is provided, please refer to Figure 1 , Figure 2 , Figure 4 A plurality of insertion holes 21 are provided on the pad 20, and at least one pin rod 35 is provided on the abutment plate 32. The pin rod 35 can be inserted into the insertion hole 21 to fix the pad 20. In the initial fixation process of the workpiece, when the abutment plate 32 abuts downward against the edge of the workpiece, the pin rod 35 is driven to be inserted into the insertion hole 21, that is, the position of the pad 20 is fixed, and the pad 20 will not continue to rotate to change the position of the workpiece.

[0041] See also Figure 3 A spring 34 is wound around each vertical rod 31, and the spring 34 is used to elastically support the support plate 32. After the limit sleeve 33 is rotated upward, the support plate 32 can be pushed upward under the elastic force of the spring 34, so as to facilitate the removal of the workpiece.

[0042] See also Figure 4 A plurality of anti-slip protrusions 36 are provided on the lower side of the butt plate 32 to improve the butt fixing effect on the workpiece.

[0043] A rubber sleeve is sleeved on the chain 40. When the chain 40 is tightened and in contact with the workpiece, the rubber sleeve protects the workpiece and avoids damage to the workpiece.
