Technical Field
[0001] This utility model relates to the field of outer diameter inspection technology, and in particular to a tool for inspecting the outer diameter of a compressor oil rod. Background Technology
[0002] In refrigerator compressors, the compressor oil rod is installed at the center of the crankshaft. The oil rod is fixed and the oil pumping function is realized by the rotation of the crankshaft and the relative movement of the oil rod. The refrigerant oil flows from the groove of the oil rod to the crankshaft and then sprays out through the hole at the top of the crankshaft. In the prior art, the outer diameter of the oil rod is generally judged to be within the preset range by an inspection tool with a through hole.
[0003] However, it's worth considering that one inspection tool can only inspect oil bars of one size. Different inspection tools are needed for each size of oil bar. When there are many product specifications, the manufacturing, management, and sourcing costs of these inspection tools become extremely high.
[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0018] This specification provides one or more embodiments of a compressor oil rod outer diameter inspection tool, such as... Figure 1 and Figure 2 As shown, it includes a support column 1, and the support column 1 has a through hole 2 for accommodating the oil rod; Several grooves 3 are provided on the inner wall of the through hole 2. Inspection strips 4 slide in the grooves 3. Elastic elements adapted to the inspection strips 4 are installed in the grooves 3. A pushing structure for pushing the inspection strips 4 to move is installed on the support column 1. When it is necessary to inspect the outer diameter of a batch of oil bars, the operator pushes the inspection strips 4 to move according to the outer diameter of the oil bar to be inspected by the pushing structure, and controls the spacing between the inspection strips 4. When the inspection strips 4 move to the preset position, the operator drives the oil bar to be inspected to pass through the through hole 2. By observing whether the oil bar can be inserted between the inspection strips 4, it can be determined whether the outer diameter of the oil bar is within the preset range. It is convenient to adjust the position of each inspection strip 4 according to the specifications of the oil bar, and thus facilitate the inspection of the outer diameter of oil bars of different specifications. One inspection tool can cover oil bars of various outer diameter specifications, eliminating the need to manufacture an inspection tool for each specification of oil bar, saving tooling manufacturing costs and storage management costs.
[0019] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the pushing structure includes a rotating sleeve 6 sleeved outside the support column 1. Two first annular grooves 7 are formed on the outer wall of the support column 1. A guide ring 8 is rotatably connected within the first annular groove 7, and the guide ring 8 is fixedly connected to the inner wall of the rotating sleeve 6. A locking unit adapted to the rotating sleeve 6 is installed on the support column 1. An abutment adapted to the inspection strip 4 is installed on the rotating sleeve 6. The abutment includes a support plate 5 fixedly installed on the inspection strip 4. A second annular groove 9 is formed on the inner wall of the rotating sleeve 6, and the end of the support plate 5 furthest from the inspection strip 4 is located within the second annular groove 9. A plurality of arc-shaped plates 10 are fixedly connected, the number of arc-shaped plates 10 and the number of support plates 5 are the same, and the arc-shaped plates 10 are provided with inclined surfaces adapted to the support plates 5. The locking unit includes a first fixing ring 11 fixedly sleeved on the outside of the support column 1, and the first fixing ring 11 is located above the rotating sleeve 6. The top of the rotating sleeve 6 is provided with a plurality of positioning grooves 13. A plurality of positioning posts 12 pass through the first fixing ring 11, and the bottom end of the positioning post 12 is located in the corresponding positioning groove 13. A presser adapted to the positioning post 12 is installed on the support column 1. The presser includes a component disposed on the first fixing ring 1. The top of the upper movable ring 14 and the bottom of the positioning post 12 are fixedly connected. A second fixed ring 15 is provided above the movable ring 14 and is fixedly connected to the support post 1. The top of the movable ring 14 and the bottom of the second fixed ring 15 are connected by several compression springs 16. When the operator drives the movable ring 14 to move upward, the compression springs 16 are compressed, and the movable ring 14 drives the positioning post 12 to slide relative to the first fixed ring 11, so that the bottom end of the positioning post 12 disengages from the corresponding positioning groove 13, releasing the restriction on the position of the rotating sleeve 6. The operator then drives the rotation... Sleeve 6 and guide ring 8 rotate relative to the first annular groove 7 and support column 1. Rotating sleeve 6 drives arc plate 10 to rotate synchronously. The inclined surface on arc plate 10 slides relative to support plate 5. Arc plate 10 can push support plate 5 and inspection strip 4 to slide relative to slide groove 3, changing the position of inspection strip 4. After the position of inspection strip 4 and rotating sleeve 6 is adjusted, the operator releases movable ring 14. Compression spring 16 drives movable ring 14 and positioning column 12 to move down so that the bottom end of positioning column 12 is inserted into the corresponding positioning groove 13, thereby fixing rotating sleeve 6 and arc plate 10 relative to support column 1.
[0020] In embodiments of this utility model, such as Figure 2 and Figure 5As shown, the elastic element includes several guide posts 17 fixedly installed on the inspection strip 4. A guide sleeve 18 is slidably sleeved on the outside of the guide post 17. The guide sleeve 18 is fixedly connected to the inner wall of the slide groove 3. A tension spring 19 is sleeved on the outside of the guide sleeve 18, and the two ends of the tension spring 19 are fixedly connected to the inner wall of the inspection strip 4 and the slide groove 3, respectively. When the pushing structure pushes the inspection strip 4 to translate, the support plate 5 drives the inspection strip 4 and the guide post 17 to slide relative to the guide sleeve 18. The tension spring 19 is in a stretched state and applies pressure to the inspection strip 4 so that the end of the support plate 5 is always in close contact with the arc plate 10. Through the design of the guide post 17 and the guide sleeve 18, the inspection strip 4 moves smoothly relative to the slide groove 3.
