Description
Technical field
The present invention relates to a kind of compressor of mechanical engineering field, the magnet frame structure that particularly relates to a kind of reciprocating compressor, specifically a kind of distortion of the piston joint that can prevent to be connected piston flange also can be kept the magnet frame structure of reciprocating compressor of the concentricity of piston.
Background technique
In general, the reciprocating compressor is by the straight reciprocating motion of piston in cylinder, and gas is sucked, compresses and discharges.
Fig. 1 is a kind of longitudinal sectional drawing of existing reciprocating compressor.As shown in Figure 1, existing reciprocating compressor is by forming as the bottom: the shell 10 that is communicated with gas suction pipe SP and gas outlet pipe DP; It is inner and play the frame unit 20 of elastic force support effect to be positioned at shell 10; Supported the reciprocating electric motor 30 of shell 10 inside and be fixed in by frame unit 20; Be mechanically connected to the compression unit 40 of reciprocating electric motor 30 and supporting frame unit 20; And elasticity is supported reciprocating electric motor 30 and vacuum vacuum spring unit 50.
Reciprocating electric motor 30 is by forming as the bottom: be fixed in the outside stabilizer 31 between middle frame 22 and the afterframe 23; Be positioned at the inboard of outside stabilizer and insert the inner stabilizer that is fixed in afterframe 23; Between outside stabilizer 31 and inner stabilizer 32 and the shifter 35 that carries out straight reciprocating motion along the direction of the magnetic line of force.
As shown in Figures 2 and 3, shifter is by forming as the bottom: between outside stabilizer 31 and inner stabilizer 32 and can move, be connected to the magnet framework 36 on the piston 42 of compression unit 40 simultaneously; For the magnet M that equidistantly installs at the outer circumferential face of above-mentioned magnet framework 36 corresponding to the winding around C that is fixed on outside stabilizer 31.
Piston joint 37 is by the connection main body 37A of cylindrical shape, and is bent to form in an end that connects main body 37A and with the adpting flange 37B that bolt B is connected piston 42 flange 42B and forms.In connecting main body 37A, for when the piston 42 that comprises shifter 35 moves back and forth, guarantee the gas communication in the outside in the magnet framework 36, be formed with ventilated port 37a; And adpting flange 37B be smooth disc-shape and in the central the zone be formed with piston hole 37b; With piston hole 37b is the center, is formed with the attachment hole 37c that the enough connecting bolt B of energy are connected in piston 42 along circumferencial direction.
Piston 42 cylindrical shapes are also slided to be inserted into the piston main body part 42A of cylinder 41 inside and to be the piston flange 42B that the disc-shape expansion is formed at the rear end of piston main body part 42A and is incorporated into the piston joint 37 of above-mentioned magnet framework 36 by the piston hole 37b by piston joint 37 and form.And on piston flange 42B,, also be formed with attachment hole 42a for attachment hole 37c corresponding to above-mentioned piston joint 37.
In Fig. 1,2,3, mark 38a is the magnet fixed hole, and mark 51 and 52 is the vacuum spring of the place ahead one side and rear one side.
The action of above-mentioned existing reciprocating compressor is as follows:
After the outside stabilizer 31 of reciprocating electric motor 30 is connected power supply, form magnetic field between outside stabilizer 31 and inner stabilizer 32, therefore, shifter 35 moves with the direction of piston 42 along magnetic field; Meanwhile, piston 42 carries out straight reciprocating motion by the inside that acts on cylinder 41 of spring unit 50, and produces pressure difference in the compression volume P of cylinder 41, thereby refrigerant gas is drawn into above-mentioned compression volume.After being compressed to certain pressure, discharge these gas.This motion will be carried out again and again repeatedly.
The adpting flange 37B of the piston flange 42B aligned magnetic iron frame 36 piston joints 37 of piston 42, with connecting bolt B the attachment hole 37c of the attachment hole 42a of piston 42 flange 42B and adpting flange 37B is run through then and tighten, thereby above-mentioned magnet framework 37 and piston 42 are linked together with the coupling nut (not shown).
But, on the magnet frame structure of above-mentioned existing reciprocating compressor, though with the flange of blue 37B of connecting bolt B press joining method and piston 42, but, because the thickness of adpting flange 37B is all thinner usually, therefore, distortion easily is distorted in connection procedure.Like this, will stagger in the center of the center of magnet framework 37 and piston 42, thereby cause the serious abrasion between piston 42 and the cylinder 41.
This shows that the magnet frame structure of above-mentioned existing reciprocating compressor still has defective, and demands urgently further being improved.
The problem that exists for the magnet frame structure that solves above-mentioned reciprocating compressor, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that the magnet frame structure of above-mentioned existing reciprocating compressor exists, the inventor is based on being engaged in this type of product specification manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, magnet frame structure in the hope of the reciprocating compressor of founding a kind of new structure, can improve the general magnet frame structure structure of the reciprocating compressor of existing routine on the market, make it have more practicability.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
Summary of the invention
