Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air compressor assembly, in particular to an assembly method of a piston air compressor. BACKGROUND

[0002] The piston air compressor is a device that realizes gas compression through the reciprocating motion of the piston, and is widely used in industrial, manufacturing, construction and other fields, especially suitable for small-scale air demand and low pressure range scenarios. The specific working process of the piston air compressor is as follows: 1. Suction process: the motor drives the crankshaft to rotate, the crankshaft drives the piston to move downward through the camshaft, the cylinder volume increases, the intake valve opens, and the air enters the cylinder through the air filter; 2. Compression process: the piston moves upward, the cylinder volume decreases, the air is compressed, the pressure rises, and when the air pressure reaches the set value, the exhaust valve opens; 3. Exhaust process: the compressed air enters the air tank through the exhaust valve, exhaust pipe and one-way valve, completing a working cycle; The crankshaft continuously rotates, and the piston reciprocates to realize continuous compression.

[0003] At present, in the assembly process of the piston air compressor, the camshaft, crankshaft, piston, shell and motor are directly assembled, however, this direct assembly method cannot ensure that the two pistons are perpendicular, which will affect the air compression effect and efficiency of the piston air compressor. SUMMARY

[0004] In view of the above-mentioned shortcomings in the prior production technology, the present application provides an assembly method of a piston air compressor, thereby.

[0005] The technical scheme adopted by the present application is as follows: An assembly method of a piston air compressor, comprising the following steps: S1, assembling the camshaft and the piston part; S2, assembling the camshaft and the two piston parts: obtaining the camshaft and the piston part after the assembly in S1, assembling the two piston parts on both sides of the camshaft respectively, and making the two piston parts perpendicular to each other; S3, synchronously assembling the shaft and the two crankshafts: inserting the synchronizing shaft into the camshaft, and then assembling the two crankshafts on both sides of the synchronizing shaft respectively, and making the crankshafts located on the outside of the camshaft to form a transmission assembly; S4, assembling the first shell: obtaining the transmission assembly in S3, and assembling the first shell to the transmission assembly; S5, assemble the cylinder head assembly, and sequentially install a plurality of the completed cylinder head assemblies to corresponding positions of the first shell; S6, assembly of the second shell: align the inlet end of the second shell with the inlet end of the cylinder head assembly, align the outlet end of the second shell with the outlet end of the cylinder head assembly, and assemble the second shell to the first shell; S7, assembly of the driving member: connect the driving end of the driving member to the synchronization shaft, and connect the driving member to the second shell, to complete the assembly of the entire piston air compressor.

[0006] Thus, when assembling the piston air compressor, the two piston parts are constrained by the first shell, and the two pistons are constrained by aligning the inlet end and the outlet end of the second shell with the inlet end and the outlet end of the cylinder head assembly. Compared with the existing direct assembly method, this method is simple in structure and easy to operate. The double-constraint method of the first shell and the second shell ensures that the two piston parts are perpendicular to each other after assembly, thereby improving the air compression effect and efficiency of the entire piston air compressor.

[0007] As a further improvement of the above technical solution: in S1, the assembly of the camshaft includes the following steps: S1-1, assembly of two first bearings: assemble two first bearings from both sides of the cam part to the cam part; S1-2, assembly of two spacers: assemble two spacers from both sides of the cam part to the cam part, and make the spacers outside the first bearings; S1-3, assembly of two second bearings: assemble two second bearings from both sides of the cam part to the cam part, and make the second bearings outside the spacers, to complete the assembly of the camshaft.

[0008] As a further improvement of the above technical solution: in S1, the assembly of the piston part includes the following steps: S1-A, assembly of two piston rings: assemble two piston rings from both sides of the piston to the piston; S1-B, assembly of two leather cups: assemble two leather cups from both sides of the piston to the piston, and make the leather cups outside the piston rings; S1-C, assembly of two leather cup pressing plates: assemble two leather cup pressing plates from both sides of the piston to the piston, and make the leather cup pressing plates outside the leather cups; S1-D, the fixing operation of the piston ring, the leather cup and the leather cup pressing plate: sequentially penetrating the locking piece through the leather cup pressing plate, the leather cup and the piston ring, and connecting the locking piece with the piston, so that the piston ring, the leather cup and the leather cup pressing plate are fixed on the piston, to complete the assembly of the piston part.

[0009] As a further improvement of the above technical solution: the S4 comprises the following steps: S4-1, assembly of the front body and the rear body: obtaining the transmission assembly in S3, respectively installing the front body and the rear body on both sides of the transmission assembly, and connecting the front body and the rear body; S4-2, assembly of the four cylinder sleeve end covers: respectively assembling the four cylinder sleeve end covers around the transmission assembly, and connecting the cylinder sleeve end covers with the front body and the rear body; Wherein: the front body is assembled on the side of the transmission assembly away from the second shell, and the rear body is assembled on the side of the transmission assembly close to the second shell. Thus, during the assembly of the first shell, the four cylinder sleeve end covers are respectively assembled around the transmission assembly to constrain the two piston parts through the four cylinder sleeve end covers, so as to ensure that the two piston parts are perpendicular to each other.

[0010] As a further improvement of the above technical solution: in S4, after the front body, the rear body and the cylinder sleeve end cover are assembled, the body front end cover and the cooling fan are sequentially assembled on the side of the front body away from the rear body.

[0011] As a further improvement of the above technical solution: the S5 comprises the following steps: S5-1, assembly of the cylinder sleeve: assembling the cylinder sleeve on the first shell; S5-2, assembly of the valve plate: first, assembling the first sealing ring on the side of the valve plate close to the cylinder sleeve, then respectively assembling the first valve piece and the second valve piece on both sides of the valve plate, and then assembling the valve plate on the cylinder sleeve and fixing the valve plate on the first shell; S5-3, assembly of the cylinder head: first, assembling the second sealing ring on the cylinder head, then assembling the second sealing ring on the first sealing ring, and fixing the cylinder head on the first shell, to complete the assembly of the cylinder head assembly.

[0012] As a further improvement of the above technical solution: in S5-2, the first sealing ring, the first valve piece and the second valve piece are all embedded in the valve plate; and the second sealing ring is embedded in the cylinder head.

[0013] As a further improvement to the above technical solution, step S6 includes the following steps: S6-1 Assembly of the flange air passage end cap: First, assemble multiple first cross-bridge pipes and multiple second cross-bridge pipes to the side of the flange air passage end cap close to the first housing, and align the first cross-bridge pipes and the second cross-bridge pipes with the inlet end of the cylinder head assembly and the outlet end of the cylinder head assembly, respectively, so as to assemble the flange air passage end cap onto the cylinder head assembly and fix the flange air passage end cap to the first housing. S6-2. Assembly of the flange air passage cover: Assemble the flange air passage cover onto the side of the flange air passage end cover away from the cylinder head assembly to complete the assembly of the second housing. Thus, during the assembly of the second housing, the first cross-bridge pipe is aligned with the inlet end of the cylinder head assembly, and the second cross-bridge pipe is aligned with the outlet end of the cylinder head assembly. Multiple first cross-bridge pipes constrain the position of the second housing relative to the first housing and relative to the cylinder head assembly, thereby constraining the two piston sections and ensuring that the two piston sections are perpendicular to each other.

[0014] As a further improvement to the above technical solution: the number of the first bridge pipe and the number of the second bridge pipe are both equal to the number of the cylinder head assembly.

[0015] As a further improvement to the above technical solution: in S7, the driving component is assembled on the flange air passage cover plate, and the driving component is located on the side of the flange air passage cover plate away from the flange air passage end cover.

[0016] The beneficial effects of this invention are as follows: In assembling a reciprocating air compressor, this invention constrains the two piston sections through a first housing and aligns the inlet and outlet ends of the second housing with the inlet and outlet ends of the cylinder head assembly to further constrain the two pistons. Compared to existing direct assembly methods, this method is simpler in structure and easier to operate. The dual constraint of the first and second housings ensures that the two piston sections are perpendicular to each other after assembly, thereby improving the air compression effect and efficiency of the entire reciprocating air compressor.

[0017] The present invention also includes the following advantages: 1. In the assembly process of the first housing, the present invention assembles four cylinder liner end caps around the transmission assembly to constrain the two piston parts through the four cylinder liner end caps, thereby ensuring that the two piston parts are perpendicular to each other.

[0018] 2. In the assembly process of the second housing, the present invention aligns the first bridge pipe with the inlet end of the cylinder head assembly and the second bridge pipe with the outlet end of the cylinder head assembly, thereby constraining the position of the second housing relative to the first housing and the position relative to the cylinder head assembly through multiple first bridge pipes and multiple bridge pipes, thereby constraining the two piston parts and ensuring that the two piston parts are perpendicular to each other.

Thus, when assembling the piston 201 air compressor, the first housing 6 constrains the two piston parts 2, and the inlet and outlet ends of the second housing 8 are aligned with the inlet and outlet ends of the cylinder head assembly 7 to constrain the two pistons 201. Compared to the existing direct assembly method, this method is simpler in structure and easier to operate. The double constraint of the first housing 6 and the second housing 8 ensures that the two piston parts 2 are perpendicular to each other after assembly, thereby improving the air compression effect and efficiency of the entire piston 201 air compressor.

[0023] For example, drive component 9 uses a motor.

S1-D, piston ring 202, cup 203 and cup pressure plate 204 fixing operation: the locking member 205 passes through the cup pressure plate 204, cup 203 and piston ring 202 in sequence, and the locking member 205 is connected to the piston 201 so that the piston ring 202, cup 203 and cup pressure plate 204 are fixed on the piston 201, so as to complete the assembly of piston part 2.

[0026] Specifically, in S2, the assembly of the camshaft 1 and the piston 2 refers to assembling the piston 201 onto the first bearing 102.

S4-2 Assembly of the four cylinder liner end caps 603: Assemble the four cylinder liner end caps 603 around the transmission assembly 5 respectively, and connect the cylinder liner end caps 603 to the front engine block 601 and the rear engine block 602. Wherein: the front body 601 is mounted on the side of the transmission assembly 5 away from the second housing 8, and the rear body 602 is mounted on the side of the transmission assembly 5 close to the second housing 8. In step S4, after the front housing 601, rear housing 602, and cylinder liner end caps 603 are assembled, the front end cap 10 and cooling fan 11 are sequentially assembled on the side of the front housing 601 away from the rear housing 602. Thus, during the assembly of the first housing 6, the four cylinder liner end caps 603 are respectively assembled around the transmission assembly 5 to constrain the two piston parts 2, thereby ensuring that the two piston parts 2 are perpendicular to each other.

[0030] Specifically, in S5-1, assembling the cylinder liner 701 onto the first housing 6 means assembling the cylinder liner 701 onto the cylinder liner end cover 603.

S6-2 Assembly of the flange air passage cover plate 804: Assemble the flange air passage cover plate 804 onto the side of the flange air passage end cover 801 away from the cylinder head assembly 7 to complete the assembly of the second housing 8. Thus, during the assembly of the second housing 8, the first cross-bridge pipe 802 is aligned with the inlet end of the cylinder head assembly 7, and the second cross-bridge pipe 803 is aligned with the outlet end of the cylinder head assembly 7. The positions of the second housing 8 relative to the first housing 6 and relative to the cylinder head assembly 7 are constrained by the multiple first cross-bridge pipes 802 and multiple cross-bridge pipes, thereby constraining the two piston parts 2 and ensuring that the two piston parts 2 are perpendicular to each other.

[0032] Specifically, in S6-1, fixing the flange air passage end cover 801 to the first housing 6 means that the flange air passage end cover 801 is connected to the rear body 602.

[0033] In this embodiment, the number of first bridge pipes 802 and the number of second bridge pipes 803 are equal to the number of cylinder head assemblies 7.

[0035] In summary, when assembling the piston 201 type air compressor, the present invention constrains the two piston parts 2 by means of the first housing 6 and aligns the inlet and outlet ends of the second housing 8 with the inlet and outlet ends of the cylinder head assembly 7, thereby constraining the two pistons 201. Compared with the existing direct assembly method, this method has a simpler structure and is easier to operate. The double constraint of the first housing 6 and the second housing 8 ensures that the two piston parts 2 are perpendicular to each other after assembly, thereby improving the air compression effect and air compression efficiency of the entire piston 201 type air compressor.
