Description

Technical field:

[0001] The utility model relates to the technical field of air compressor processing equipment, and more specifically to a parallelism detection tool for installing a moving disc of an air compressor. Background technology:

[0002] Air compressors are the main body of air source devices and are widely used in industrial production. Oil-free scroll air compressors provide clean, oil-free compressed air and are a new type of air compressor with development prospects.

[0003] When installing an oil-free scroll air compressor, higher precision is required. It is necessary to ensure that the parallelism of the outer end surface of the plate on which the moving disk is installed meets the requirements after it is fixed as a whole. However, it is generally placed horizontally, and then the upper static disk is placed and then rotated to check whether there are friction problems between the two. If there is friction, it means that the adjustment is not in place, and the upper static disk needs to be removed and adjusted, which is very troublesome. Utility model content:

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a parallelism detection tool for the moving plate of an air compressor, which can place the air compressor with the moving plate installed on the top surface of the anti-collision plate, insert the moving plate into the central through groove, and fix the front end surface of the air compressor housing by connecting bolts, so as to detect the parallelism of the front wall surface of the radially extending edge of the moving plate, and the detection is accurate and convenient.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A parallelism detection tool for the installation of a dynamic plate of an air compressor comprises a fixed base plate, a connection detection plate in a vertical state is fixed to the front top surface of the fixed base plate, a central through slot is formed in the middle of the connection detection plate, two micrometers are installed on the connection detection plate at the left and right sides of the lower part of the central through slot, and a micrometer is installed on the connection detection plate at one side of the upper part of the central through slot; the three micrometers are distributed at three positions of the central through slot, so that the detection is more accurate.

[0007] The detection rods of all micrometers are inserted into the corresponding transverse through holes on the connection detection plate, and the rear ends of the detection rods extend out of the rear ends of the transverse through holes to facilitate detection.

[0008] The upper and lower left and right sides of the connection detection plate are formed with connection through holes, the screw portion of the connection bolt is inserted into the corresponding connection through hole, and the rear end of the screw portion of the connection bolt extends out of the rear end of the corresponding connection through hole.

[0009] The rear wall surfaces of the left and right parts of the connection detection plate are fixedly connected to the left bracket and the right bracket by multiple bolts, and the bent parts formed at the bottom of the left bracket and the right bracket are fixedly connected to the fixed bottom plate by bolts.

[0010] An anti-collision plate is fixed on the top surface of the fixed bottom plate, and the left and right parts of the front wall surface of the anti-collision plate are both formed with mounting grooves extending backwards, and the bending parts of the left bracket and the right bracket are inserted into the corresponding mounting grooves.

[0011] The connection detection plate is fixedly connected with three clamping blocks by bolts, and each clamping block is clamped with a micrometer.

[0012] The outstanding effects of the utility model are:

[0013] 1. It can place the air compressor with the installed moving disc on the top surface of the anti-collision plate, insert the moving disc into the central through groove, and fix the front end surface of the air compressor housing by connecting bolts to detect the parallelism of the front wall surface of the radially extending edge of the moving disc. The detection is convenient and accurate.

[0014] 2. Its detection state is that the air compressor is fixed on its side for detection, and this state is the placement state of the air compressor when it is subsequently installed to the whole machine, making it closer to the working condition and making its detection accuracy higher.

[0016] Figure 2 It is a partial side view of the utility model;

[0017] Figure 3 It is a partial top view between the fixed bottom plate and the anti-collision;

[0018] Figure 4 It is a schematic diagram of the local structure where the detection board is connected. Specific implementation method:

[0019] For example, see Figures 1 to 4As shown, a parallelism detection tool for the dynamic plate installation of an air compressor includes a fixed base plate 10, the top surface of the fixed base plate 10 is pressed against an anti-collision plate 60, and the left and right parts of the front wall surface of the anti-collision plate 60 are both formed with mounting grooves extending backward, the bent parts of the left bracket 40 and the right bracket 50 are inserted into the corresponding mounting grooves, and the bent parts of the left bracket 40 and the right bracket 50 are fixedly connected to the top surface of the fixed base plate 10 by bolts, and the left and right top surfaces of the anti-collision plate 60 are pressed against a strip plate 61 extending forward and backward, and the strip plate 61 is fixedly connected to the fixed base plate 10 by bolts, and the anti-collision plate 60 is clamped between the strip plate 61 and the fixed base plate 10, and the screw portion of the bolt is inserted into the through hole of the strip plate 61 and the corresponding through hole of the anti-collision plate 60, and the bottom end of the screw portion of the bolt extends out of the bottom surface of the anti-collision plate 60 and is screwed to the fixed base plate 10.

[0020] The anti-collision plate 60 is a nylon plate, which can prevent the air compressor housing and the fixed bottom plate 10 from being damaged or rubbed against each other during subsequent inspection.

[0021] Further, the left and right rear walls of the connection detection plate 20 are fixedly connected to the left bracket 40 and the right bracket 50 by multiple bolts, and a central through slot 21 is formed in the middle of the connection detection plate 20, and two micrometers 30 are installed on the connection detection plate 20 at the left and right sides of the lower part of the central through slot 21, and a micrometer 30 is installed on the connection detection plate 20 at one side of the upper part of the central through slot 21;

[0022] The detection rods of all the micrometers 30 are inserted into the corresponding transverse through holes 22 on the connection detection plate 20 .

[0023] The upper and lower left and right sides of the connection detection plate 20 are formed with connection through holes, and the screw portion of the connecting bolt 1 is inserted into the corresponding connecting through hole, and the rear end of the screw portion of the connecting bolt 1 extends out of the rear end of the corresponding connecting through hole.

[0024] Furthermore, three clamping blocks 70 are fixedly connected to the connection detection plate 20 by bolts, and each clamping block 70 clamps a micrometer 30 .

[0025] The clamping block 70 is formed with a plug-in through hole in the middle, and two extensions extending outward are formed on one side of the plug-in through hole. The two extensions are fixed by bolts. The clamping part of the dial gauge 30 is in the plug-in through hole, and its outer side wall is pressed against the inner side wall of the plug-in through hole. By rotating the bolts of the two extensions, the clamping part of the dial gauge 30 can be clamped and fixed. When the bolts of the two extensions are loosened, the outer side wall of the plug-in through hole and the outer side wall of the clamping part of the dial gauge 30 will not be pressed against each other, so the dial gauge 30 can be removed, which is very convenient.

[0026] Furthermore, a central groove is formed in the middle of the anti-collision plate 60, and the rotating part of the central fixing bolt 2 is inserted into the central groove. The screw part of the central fixing bolt 2 is inserted into the corresponding through hole on the bottom surface of the central groove and is screwed to the fixed base plate 10, and the bottom surface of the rotating part of the central fixing bolt 2 is pressed against the bottom surface of the central groove.

[0027] The left bracket 40 and the right bracket 50 are both L-shaped, and the rear wall surfaces connecting the left and right parts of the detection plate 20 are fixedly connected to the vertical plate parts of the left bracket 40 and the right bracket 50 by multiple bolts.

[0028] When the present embodiment is used, the air compressor mainframe with the movable disc installed is first placed on the top surface of the anti-collision plate 60, and the movable disc is moved forward along the top surface of the anti-collision plate 60 so that the movable disc is inserted into the central through groove 21 in the middle of the connection detection plate 20. Then, the connection bolt 1 is rotated so that the screw portion of the connection bolt 1 is screwed to the front end surface of the air compressor mainframe, and the front end surface is pressed against the rear end surface of the connection detection plate 20 (generally, the connection between the screw portion of the connection bolt 1 and the front end surface of the air compressor mainframe only requires rotating the connection bolt 1 about 2 turns). The four connecting bolts 1 are adjusted by diagonal rotation. At this time, the front wall of the radially extending edge of the moving plate is pressed against the rear ends of the detection rods of the three micrometers 30. Then, the values ​​of the three micrometers 30 are observed. When the values ​​of the three micrometers 30 are between 0.110mm and 0.140mm, and the difference between the three data is 0.01mm, it means that the requirements are met. For those that do not meet the requirements, it is necessary to rotate the connecting bolts 1, separate the air compressor host from the connecting detection plate 20, and then adjust it. The detection is convenient and accurate.

[0029] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
