[0036] Refer to the attached Figure 1-4 The utility model provides a device for detecting the symmetry of the keyway of the movable scroll of a scroll compressor, comprising the following structure:

[0037] The base 1 has a sliding seat 2 slidably connected to the front and rear sides of the inner wall bottom of the base 1. A mounting plate 3 is fixed on the top of the sliding seat 2. The opposite sides of the two mounting plates 3 are planar structures.

[0038] Two brackets 4, the tops of the two brackets 4 are fixedly connected to the left and right sides of the bottom of the linear module 5 respectively, and the top movable end of the linear module 5 is provided with a truss 6, and the left and right ends of the top of the truss 6 are slidably connected with a positioning seat 8.

[0039] In this embodiment, the front and rear ends of the base 1 are movably connected to the front and rear ends of the slide rod 11 respectively, and the outer side of the slide rod 11 is slidably connected to the bottom end of the slide seat 2.

[0040] The slide rod 11 cooperates with the slide seat 2 to complete the sliding guide on the base 1 under the slide seat 2.

[0041] In this embodiment, a locking bolt 21 is threadedly connected to the bottom of the sliding seat 2 , and the bottom of the locking bolt 21 abuts against the outer side of the sliding rod 11 .

[0042] The locking bolt 21 completes the working position adjustment of the slide 2 outside the slide rod 11. When performing inspection operations on movable scrolls of different specifications, it is necessary to use professional measuring tools to adjust the working positions of the two slides 2 on the base 1 and complete the working position locking adjustment of the two dial indicators 31 on the mounting plate 3.

[0043] In this embodiment, a mounting groove is fixedly provided on the top of the mounting plate 3 , and a dial indicator 31 is fixedly provided on the top of the mounting plate 3 . The centers of the detection heads of the two dial indicators 31 are on the same axial direction.

[0044] The setting of the two dial indicators 31 facilitates the inspection of the front and rear sides of the movable scroll when the linear module 5 drives the movable scroll on the truss 6 to move. The inspector observes the changes in the values ​​on the dial indicators 31 to determine whether the symmetry of the keyway of the movable scroll meets the product processing requirements.

[0045] In this embodiment, guide grooves are fixedly provided on both ends of the left and right sides of the truss 6, and the guide grooves cooperate with the outer sides of the positioning seat 8. The left and right ends of the truss 6 are movably connected with guide rods 7. The outer sides of the guide rods 7 are movably sleeved with the bottom of the positioning seat 8. The outer sides of the guide rods 7 are sleeved with a limiting spring 71. One end of the limiting spring 71 is clamped with the outer side of the positioning seat 8, and the other end of the limiting spring 71 is clamped with the end of the truss 6.

[0046] The guide groove and the guide rod 7 cooperate to complete the working guidance and movement stability of the positioning seat 8 on the truss 6. The design of the limit spring 71 pushes the two positioning seats 8 toward the middle of the truss 6. The user needs to engage the keyway on one side of the bottom of the movable scroll with the positioning pin 81 and push the positioning pin 81 to complete the engagement of the keyway on the other side of the movable scroll with the positioning pin 81 to complete the inspection and assembly of the movable scroll. The linear module 5 drives the movable scroll to move between the inspection heads of the two dial indicators 31 to complete the keyway symmetry detection of the movable scroll, thereby improving the keyway symmetry detection efficiency of the movable scroll.

[0047] In this embodiment, a positioning pin 81 is fixed to the top of the positioning seat 8, and the opposite sides of the two positioning pins 81 are respectively engaged with the key grooves at the bottom of the movable scroll, and the center line of the opposite sides of the two positioning pins 81 is perpendicular to the center line of the detection heads of the two dial indicators 31.

[0048] If the two keyways at the bottom of the movable scroll are skewed, it cannot be smoothly assembled on the two locating pins 81, that is, it is judged that the symmetry of the keyway of the movable scroll does not meet the product requirements. If the movable scroll is normally assembled on the two locating pins 81, it is judged that the keyway is symmetrical about the middle of the movable scroll. By testing with two dial indicators 31, it is judged whether the keyway is symmetrical about the middle of the movable scroll.

[0049] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
