[0032] A horizontal cylindrical cavity is opened in the middle of the mounting seat 100, and a bearing seat 101 is installed on the inner wall of the cavity. A product fixing plate 109 is fixed to one end of the rotating shaft 103, and a scale is provided on one side of the product fixing plate 109, and a workpiece to be measured is fixed to the other side. The other end of the rotating shaft 103 passes through the axial hole provided in the middle of the clamping plate 108 and the bearing of the bearing seat 101 in sequence, and is fixedly inserted into the through hole opened at one end of the rotating wheel 104. A rotating plunger 105 is installed at the other end of the rotating wheel 104. The clamping plate 108 is fixedly installed on the end face of the mounting seat 100 close to the product fixing plate 109. The axial hole provided in the middle of the clamping plate 108 and the rotating shaft 103 are clearance-matched, and the rotating shaft 103 is movably sleeved in the bearing of the bearing seat 101.

[0033] A radial threaded hole is opened inside the clamping plate 108, and a knob handle 107 is threadedly connected to the threaded hole. By screwing the knob handle 107, the lower end of the knob handle 107 passes through the threaded hole of the clamping plate 108 and is fixed in a hemispherical groove opened on the outer wall of the rotating shaft 103, thereby fixing the rotating shaft 103 and limiting the circumferential and axial movement of the rotating shaft 103.

[0034] The end surface of the mounting seat 100 close to the rotating wheel 104 is provided with a plurality of positioning holes. By pressing in or pulling out one end of the rotating plunger 105, the other end of the rotating plunger 105 is driven to be inserted into or pulled out of the positioning hole, thereby limiting or not limiting the rotating wheel 104 in the circumferential direction relative to the mounting seat 100.

[0035] like Figure 3 As shown, the end surface of the mounting seat 100 close to the rotating wheel 104 is provided with three positioning holes, and copper sleeves are arranged in the positioning holes. The three positioning holes are evenly spaced along the circumferential direction, wherein two positioning holes are located on the left and right symmetrical sides of the horizontal radial direction of the central axis of the rotating shaft 103, and the other positioning hole is located on the upper side or the lower side of the vertical radial direction of the central axis of the rotating shaft 103, wherein the positioning hole on the left side is a 0 degree positioning hole, the positioning hole on the right side is a 180 degree positioning hole, and the positioning hole on the upper side or the lower side is a 90 degree positioning hole;

The bearing fixing ring 102 and the rotating wheel 104 do not contact.

[0038] The use process of positioning fixture 1 is as follows:

[0039] When the unbalance measurement of the workpiece to be measured on the product fixing plate 109 is performed, the knob handle 107 is first turned in the forward direction to fix the lower end of the knob handle 107 in the hemispherical groove of the outer wall of the rotating shaft 103, one end of the rotating plunger 105 is pulled out and the rotating wheel 104 is positioned to the 90-degree positioning hole, and one end of the rotating plunger 105 is pressed in to insert the other end of the rotating plunger 105 into the 90-degree positioning hole. During the process, the rotating wheel 104 drives the rotating shaft 103 and the product fixing plate 109 to rotate. At this time, the end face of the product fixing plate 109 faces the horizontal radial direction of the central axis of the rotating shaft 103, and then the knob handle 107 is turned in the reverse direction to fix the lower end of the knob handle 107 in the hemispherical groove of the outer wall of the rotating shaft 103, and the rotating shaft 103 is limited in circumferential and axial movement. At this time, the unbalance measurement of the workpiece to be measured on the product fixing plate 109 is performed through the test bench 0;

[0040] When the workpiece to be measured on the product fixing plate 109 is to be corrected for imbalance, that is, the workpiece to be measured is corrected by adding glue and weighting, firstly, the knob handle 107 is turned in the positive direction, and the lower end of the knob handle 107 is not fixed in the hemispherical groove of the outer wall of the rotating shaft 103, and one end of the rotating plunger 105 is pulled out and the rotating wheel 104 is positioned to the 0 degree positioning hole or the 180 degree positioning hole, and then one end of the rotating plunger 105 is pressed in to insert the other end of the rotating plunger 105 into the 0 degree positioning hole or the 180 degree positioning hole. During the process, the rotating wheel 104 drives the rotating shaft 103 and the product fixing plate 109 to rotate. At this time, the end face of the product fixing plate 109 is facing the vertical direction. The imbalance correction does not need to fix the lower end of the knob handle 107 in the hemispherical groove of the outer wall of the rotating shaft 103. At this time, the workpiece to be measured on the product fixing plate 109 is corrected for imbalance by adding glue and weighting;

[0041] The positioning fixture 1 of the utility model has a simple structure, is easy to operate, and has good stability. The knob plunger 105 and the rotating wheel 104 can cooperate to realize the positioning of the workpiece to be measured at different angles. When the positioning fixture 1 is used in an unbalance machine, it can not only perform measurements but also perform corrections. The front or back side of the workpiece to be measured can be facing upwards, which is convenient for adding glue and correction, thereby improving the efficiency of product imbalance correction.
