Abstract
A refrigerator compressor rotor clamp comprises a handle (1). The handle (1) is welded with the upper end of a clamp tube (4), a side support rod (3) is fixedly connected on the handle (1) and is hinged with the middle of an upper connecting rod (2), the lower end of an upper connecting rod (2) is hinged with one end of a lower connecting rod (5), the other end of the lower connecting rod (5) penetrates the clamp tube (4) to be hinged on a pull rod (6), the pull rod (6) is inserted into the clamp tube (4), a stopper (7) is fixedly connected in the clamp tube (4), one end of a spring (8) is fixedly connected with the stopper (7) and the other end of the same is fixedly connected with the pull rod (6). Due to the fact that the diameter of the clamp tube is smaller than the inner diameter of a rotor, the heated rotor is clamped after being pulled by the pulling rod by means of the principle that expansion diameter of the clamp tube is larger than the inner diameter of the rotor, the number of reworked or scrapped rotors during shrinkage fit is decreased, work efficiency is improved and convenience is brought for people's work.
Description
Technical field:
The present invention relates to clamping apparatus technical field, clamp pincers more specifically to a kind of refrigerator press rotor.
Background technology:
At present, hot jacket rotor is a mature technology comparatively in refrigerator press assembling, in assembling, first rotor is heated in heating furnace, after heating, immediately rotor is assembled on the bent axle of press, clamping now rotor often uses kilocalorie clamp rotor outer circle or provokes rotor with plug and fill on bent axle, in this process, often occur that rotor drops on ground or rotor outer circle damages the phenomenon of doing over again, production efficiency is low, workpiece do over again scrap many.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and providing a kind of refrigerator press rotor to clamp pincers, it has effectively solved the rotor after heating and has clamped problem, has reduced the quantity that workpiece is done over again or scrapped, improve operating efficiency, for people's work has brought convenience.
Technology solution of the present invention is as follows:
A kind of refrigerator press rotor clamps pincers, it comprises handle, the upper end of handle and clamp welds together, on handle, be fixedly connected with side pole, the middle part of side pole and upper connecting rod is hinged, and the lower end of upper connecting rod and one end of lower link are hinged, the other end of lower link is hinged on pull bar through clamp, pull bar is plugged in clamp, is fixedly connected with block in clamp, and one end of spring is fixedly connected on block, the other end is fixedly connected on pull bar;
On clamp, form elongated slot, the lower nozzle that elongated slot is cut apart clamp becomes several arc plates, and pull bar lower end diameter is greater than the diameter of the lower nozzle of clamp.
Described pull bar bottom has the shrinkage pool of bullet shape.
Beneficial effect of the present invention is:
1, this rotor clamps to clamp and utilizes clamp diameter to be less than rotor internal diameter, the principle that clamp swell diameter is greater than in rotor after on pull bar clamps the rotor after heating, it has reduced the quantity that rotor is done over again or scrapped in hot jacket process, has improved operating efficiency, for people's work has brought convenience.
2, this rotor clamps pincers pull bar bottom the shrinkage pool of bullet shape, is convenient to rotor and clamps pincers and be placed on the fuel sucking pipe on bent axle, for rotor hot jacket has played good guide effect, has improved production efficiency.
Brief description of the drawings:
Structural representation when Fig. 1 is of the present invention unclamping;
Structural representation when Fig. 2 is of the present invention unclamping;
Fig. 3 is the schematic appearance of 4 clamp lower ends in Fig. 1;
In figure: 1, handle; 2, upper connecting rod; 3, side pole; 4, clamp; 5, lower link; 6, pull bar; 7, block; 8, spring.
Detailed description of the invention:
Embodiment: see shown in Fig. 1,2, a kind of refrigerator press rotor clamps pincers, it comprises handle 1, handle 1 welds together with the upper end of clamp 4, on handle 1, be fixedly connected with side pole 3, side pole 3 is hinged with the middle part of upper connecting rod 2, one end of the lower end of upper connecting rod 2 and lower link 5 is hinged, the other end of lower link 5 is hinged on pull bar 6 through clamp 4, pull bar 6 is plugged in clamp 4, in clamp 4, be fixedly connected with block 7, one end of spring 8 is fixedly connected on block 7, the other end is fixedly connected on pull bar 6;
On clamp 4, form elongated slot, the lower nozzle that elongated slot is cut apart clamp 4 becomes several arc plates, and pull bar 6 lower end diameter are greater than the diameter of the lower nozzle of clamp 4.
Described pull bar 6 bottoms have the shrinkage pool of bullet shape.
Operation principle: the rotor during by releasing orientation clamps pincers and inserts in rotor inner hole, and then hold with a firm grip handle 1 and upper connecting rod 2, open connecting rod 2 lower ends outward, drives lower link 5 to open outward, and connecting rod 5 drives pull bar 6 up to promote; Pull bar 6 up promotes and is expanded in be shaped slotted lower end of clamp 4, make clamp 4 mutually stuck with rotor internal diameter, thereby can cross movable rotor to bent axle, and the appearance similar of fuel sucking pipe on shrinkage pool and the bent axle of pull bar bottom is convenient to rotor to clamp and clamp on the fuel sucking pipe being placed on bent axle.Then unclamp handle 1 and upper connecting rod 2, pull bar 6 returns to home position under the effect of spring 8, and rotor drops from clamping pincers, completes assembling process.The structure of clamp 4 lower ends as shown in Figure 3.
