Abstract
The utility model discloses a tool for assembling a piston, a connecting rod and a piston pin. The tool comprises a base, wherein a left side plate is connected to one end of the base, and a right side plate is connected to the other end of the base; a round hole is formed in the left side plate, a piston positioning cylinder is matched with the round hole, a jacking shaft is in threaded connection with the right side plate, the left end of the jacking shaft is connected with a push plate, and the right end of the jacking shaft is connected with a crank; a support frame is fixedly connected to the base through a bolt, and a piston pin support plate is arranged above the support frame; and the piston positioning cylinder and the jacking shaft are arranged coaxially. The tool has the advantages of time and labor saving, high assembling efficiency and low labor intensity of an operator.
Description
Technical field
The utility model relates to a kind of frock, is used for the frock of piston, connecting rod and piston pin assembling.
Background technology
At present, the assembly method between piston of engine, connecting rod and the piston pin is piston to be stood upside down to be placed on the mounting platform earlier, utilizes the crane instrument that connecting rod is sling; The small end of connecting rod is aimed in the little retaining of piston, and the piston pin assembling has been removed in manual work, with piston pin hole and wrist-pin hole alignment; Discharge water flat piston pin and slowly propelling again; Up to the retaining ring for piston pin mouth place of the other end, the retaining ring for piston pin of both sides is installed then, accomplish the installation of piston, connecting rod, piston pin.This mode wastes time and energy, and efficiency of assembling is low, and labour intensity is big, and is particularly more inconvenient to the assembling of piston, connecting rod and the piston pin of large-scale diesel engine.
Summary of the invention
The purpose of the utility model provide a kind of time saving and energy saving, easy to assembly, efficient is high is used for the frock of piston, connecting rod and piston pin assembling, overcomes the deficiency of prior art.
The frock that is used for piston, connecting rod and piston pin assembling of the utility model comprises base, is connected with left plate at an end of base, and the other end is connected with right plate; On left plate, have and be furnished with the piston positioning cylinder in circular hole and the circular hole, on right plate, be connected with apical axis through thread connecting mode, the left end of apical axis is connected to push pedal, and the right-hand member of apical axis is connected to crank; Bolt is connected with bracing frame on base, and the bracing frame top is provided with the piston pin support plate; Described piston positioning cylinder, the coaxial setting of apical axis.
The frock that is used for piston, connecting rod and piston pin assembling of the utility model is inverted in piston above the base during use, and the piston positioning cylinder is inserted in the hole on the left plate; The right part of piston positioning cylinder is got in the piston pin hole on the piston, and a crane is sling by connecting rod and small end head gets into piston cavity downwards, and piston pin places on the piston pin support plate; This moment piston pin axial line just with piston on piston pin hole, the center line of wrist-pin end of connecting rod, the axial line of piston positioning cylinder overlap; Rotate apical axis then, push pedal is moved to the left, lean the right side of piston pin; Piston pin is moved to the left; Thereby in the entering piston pin hole and penetrate in the wrist-pin hole, gudgeon pin shaft is when position suitable, and the retaining ring for piston pin of packing into gets final product.The advantage that this frock has is time saving and energy saving, efficiency of assembling is high, labor intensity of operating staff is low.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is that sketch map is looked on a left side shown in Figure 1;
Fig. 3 is an A-A sectional schematic diagram shown in Figure 1.
The specific embodiment
Like Fig. 1,2, shown in 3: 1 is base, is connected with left plate 2 at an end of base 1, and the other end is connected with right plate 13; On left plate 2, have and be furnished with piston positioning cylinder 3 in circular hole and the circular hole, the right half diameter of piston positioning cylinder 3 is less than the diameter of left half, and the diameter of right half and the piston pin aperture on the piston match.
On right plate 13, be connected with apical axis 8 through thread connecting mode, the left end of apical axis 8 is connected to push pedal 7, and the right-hand member of apical axis 8 is connected to crank.
Bolt is connected with flute profile and the downward bracing frame 9 of notch on base 1, and bracing frame 9 tops are provided with piston pin support plate 12, and piston pin support plate 12 is V-shaped.Piston positioning cylinder 3, apical axis 8 coaxial settings.
In order to adjust the height of left plate 2 and right plate 13; Bolt on left plate 2 and the right plate 13 penetrates the elongated hole of the long above-below direction in hole; Bolt on the bracing frame 9 penetrates the hole and also is the elongated hole of above-below direction; To guarantee left plate 2, right plate 13, bracing frame 9 conversion height and positions, satisfy the assembling of the piston of all size.
During use piston 4 is inverted in above the base 1, in the hole on the piston positioning cylinder 3 insertion left plates 2, the right part of piston positioning cylinder 3 is got in the piston pin hole on the piston 4; Play that crane is sling connecting rod 5 and small end head gets into the inner chamber of piston 4 downwards; Piston pin 6 places on the piston pin support plate 12, this moment piston pin 6 axial line just with piston 4 on piston pin hole, the center line of connecting rod 5 small ends, the axial line of piston positioning cylinder 3 overlap, rotate apical axis 8 then; Push pedal 7 is moved to the left; Lean the right side of piston pin 6, piston pin 6 is moved to the left, thereby get in the piston pin hole and penetrate in the connecting rod 5 little stomidiums; When piston pin 6 axial locations were suitable, the retaining ring for piston pin of packing into got final product.
