[0020] Example 1
[0021] This embodiment provides Figure 1 to Figure 4A tooling fixture for polishing the outer side of an expansion ring is shown, comprising a tapered shank seat 1, which is composed of a horizontal tapered shank portion 11 and a vertical fixed seat 12. The shank end on the left side of the tapered shank portion 11 is fixedly connected to the middle of the left side surface of the fixed seat 12. A circle of placement grooves 2 for placing the expansion ring is provided on the outer circle of the right side surface of the fixed seat 12. A pressure plate 3 is vertically provided on the right side of the fixed seat 12, and the pressure plate 3 is fixed to the right side surface of the fixed seat 12 through a fixing assembly 4.
[0022] When in use, first install the parts on the fixture, and then place the expansion ring to be processed in the placement groove 2 on the fixed seat 12, and then fix the expansion ring tightly on the fixed seat 12 through the pressure plate 3, and fix the pressure plate 3 through the fixing component 4. After placing it, place the tapered handle seat 1 horizontally as a whole and fix it on a lathe or other equipment, and then the outside of the expansion ring can be ground and polished by the lathe, thereby solving the problem that the expansion ring cannot be well fixed during each processing, causing the expansion ring to shake during the grinding and polishing process, thereby improving the qualified rate of the final product processed and improving work efficiency.
[0023] Furthermore, the fixing assembly 4 includes a plurality of through holes 41 opened on the pressure plate 3, the through holes 41 are circumferentially arranged on the pressure plate 3, and the spacing between the plurality of through holes 41 is smaller than the ring diameter of the placement groove 2, and also includes bolts 42 corresponding one-to-one to the plurality of through holes 41, and the fixing seat 12 is also provided with screw holes corresponding one-to-one to the bolts 42, the bolts 42 horizontally pass through the through holes 41 and are inserted into the fixing seat 12, and the bolts 42 are threadedly connected to the fixing seat 12 in the screw holes of the fixing seat 12.
[0024] The bolts 42 are provided so that the bolts 42 pass through the pressing plate 3 and cooperate with the screw holes on the fixing seat 12, and the pressing plate 3 is tightly fixed on the fixing seat 12 to form a whole, so that the pressing plate 3 tightly fixes the expansion ring on the fixing seat 12, thereby increasing stability and preventing the expansion ring from shaking during processing, thereby improving the qualified rate of the finished product.
[0025] Furthermore, a washer 5 is vertically provided at each through hole 41 . The washer 5 is located between the pressure plate 3 and the head of the bolt 42 . The washer 5 is sleeved on the bolt 42 .
[0026] The washer 5 provided can be used to protect the pressure plate 3 so that the bolts 42 will not cause damage to the surface of the pressure plate 3 when fixing the pressure plate 3, disperse the pressure of the bolts 42 on the pressure plate 3, increase the fixing area of the bolts 42 on the pressure plate 3, and improve the stability of the expansion ring fixing the pressure plate 3, wherein the washer 5 is a waist-shaped groove, and one end of the waist-shaped groove of the washer 5 is opened.
[0027] Furthermore, the number of the through holes 41 is four, and the number of the bolts 42 is four.
[0028] By setting four through holes 41 and bolts 42, the bolts 42 cooperate with the pressure plate 3, and the expansion ring can be evenly fixed from four directions. At the same time, the pressure plate 3 is evenly stressed to avoid excessive stress at a certain point of the pressure plate 3, which may cause damage to the expansion ring.
[0029] Furthermore, a positioning boss 6 protruding outward is provided in the middle of the right side of the fixing seat 12 , and the boss is inserted into the left side of the pressing plate 3 .
[0030] The positioning boss 6 can not only play a positioning role in fixing the pressing plate 3 and the fixing seat 12 together, making it convenient for workers to install, but also play a role in limiting and fixing the pressing plate 3, further improving the fixing effect of the expansion ring.
