Description

Technical Field

[0001] The utility model belongs to the technical field of compressor valve plates, in particular to a mounting fixture for a valve plate component of an automobile air-conditioning compressor. Background Art

[0002] The valve plate components of the automobile air-conditioning compressor include the inner valve plate, valve plate, outer valve plate, and outer valve protection plate, which are arranged in sequence and fixed by screws. The outer valve plate and the outer valve protection plate have five corners and are similar in shape. The outer valve plate is slightly smaller than the outer valve protection plate. The inner valve plate and the outer valve plate are elastic, and the outer valve protection plate is a rigid structure. The function of the inner valve plate is to control the five outer holes on the valve plate, and the outer valve plate is used to control the five inner holes on the valve plate. The outer valve protection plate is used to control the maximum angle of the outer valve plate leaving the valve plate.

[0003] Existing automotive air-conditioning compressor valve plate components are difficult to remove after installation. For example, a valve plate assembly fixture for automotive air-conditioning compressors, as shown in Patent Publication No. CN211163009U, includes an annular support seat and a polygonal rotating block. After the valve plate assembly is installed, the aforementioned patent requires manual removal of the valve plate from the annular opening. Due to the small gap between the annular opening and the valve plate, removal is difficult, impacting processing efficiency.

[0004] To this end, we propose an automobile air-conditioning compressor valve plate component mounting fixture to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 A fixture for mounting valve plates of automotive air-conditioning compressors includes a fixture assembly, a valve plate assembly, and a positioning assembly. The fixture assembly includes a cylindrical support base 1 with vertical slideways 2 on both sides. A movable plate 3 slides up and down within the slideways 2. An annular opening 4 is provided on the top surface of the support base 1. Below the annular opening 4, movable cavities 5 are provided on both sides of the support base 1. A top block 6 slides up and down within the movable cavity 5. The top block 6 is connected to the movable plate 3 on the same side via a connecting rod 7. A clamping block 8 is provided at the upper end of the movable plate 3, and a drive assembly for driving the two movable plates 3 to move synchronously is provided at the lower portion of the support base 1.

[0021] The valve plate assembly includes a valve seat 9, an upper valve disc 10, a lower valve disc 11, and bolts 12. The positioning assembly includes a fixed lower positioning block 13 and a movable upper positioning block 14. Lower positioning block 13 is fixedly connected to the bottom surface of annular opening 4, thereby positioning lower valve disc 11 and valve seat 9. Upper positioning block 14 is hinged to the top of annular opening 4, thereby positioning upper valve disc 10. This hinged connection prevents upper positioning block 14 from interfering with handling of the valve plate assembly.

[0022] To use this automotive air-conditioning compressor valve plate assembly mounting fixture, first place the bolt 12 in the center of the annular opening 4, then sequentially fit the lower valve disc 11 and valve seat 9 onto the bolt 12. After positioning the lower valve disc 11 and valve seat 9 with the lower positioning block 13, the drive assembly drives the two movable plates 3 downward synchronously until the clamping block 8 secures the valve seat 9. Next, fit the upper valve disc 10 onto the bolt 12, and after positioning it with the upper positioning block 14, the valve plate assembly is installed using nuts and bolts 12.

[0023] After installation is completed, the two movable plates 3 are driven to move upward synchronously by the driving assembly, thereby unlocking the valve plate assembly by the clamping block 8. The movable plate 3 continues to move upward, and the top block 6 moves upward accordingly and lifts the valve plate assembly from the annular opening 4.

[0024] The outer surface of the support base 1 is provided with threads 15. The drive assembly includes a rotating block 16 that is sleeved onto the support base 1. The lower end of the movable plate 3 is L-shaped, and a spring 17 is fixedly connected between the lower end of the movable plate 3 and the bottom of the chute 2. When the rotating block 16 rotates downward, the movable plate 3 moves downward; when the rotating block 16 rotates upward, the spring 17 drives the movable plate 3 upward synchronously.

[0025] To further improve work efficiency, the top surface of the top block 6 is inclined, so that after the top block 6 lifts the valve plate assembly, the valve plate assembly slides out the material against the inclined top surface of the top block 6. The inclined upper side of the top surface of the top block 6 is located on the side where the positioning assembly is located, thereby preventing the valve plate assembly from colliding with the positioning assembly.

[0026] To minimize interference with the installation of the valve plate assembly, the clamping block 8 cannot be too large. However, a smaller clamping block 8 has limited adaptability when installed on valve plate assemblies of varying sizes. To address this issue, a screw 18 extends through the thread 15 at the upper end of the movable plate 3. One end of the screw 18 is rotatably connected to one side of the clamping block 8. Rotating the screw 18 adjusts the extension length of the clamping block 8, thereby accommodating the installation requirements of valve plate assemblies of varying sizes.

[0027] The side of the clamping block 8 is fixedly connected to a limiting rod 19, and the limiting rod 19 is slidably arranged through the upper end of the movable plate 3. The clamping block 8 is limited by the limiting rod 19 to prevent the clamping block 8 from rotating with the screw 18.

[0028] A placement opening 20 for the bolt 12 is fixedly opened in the middle of the annular opening 4. The placement opening 20 is used to position the bolt 12, that is, to locate the center of the valve seat 9, the upper valve disc 10, and the lower valve disc 11. The lower positioning block 13 is then used to position the lower valve disc 11 and the valve seat 9, and the upper positioning block 14 is used to position the valve seat 9 and the upper valve disc 10.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
