Description
Technical field
The utility model relates to a kind of reciprocating saw.
Background technology
Existing reciprocating saw includes reduction box loam cake, towing plate, reciprocating lever and ball bearing, and the reciprocating lever cross-under is in ball bearing, and towing plate and reciprocating lever move back and forth.Reciprocating lever is back and forth generating heat in the process; After oil thrown away or dryout; To not have grease lubrication between reciprocating lever and needle bearing, reciprocating lever and the ball bearing, and make reciprocating lever and needle bearing, ball bearing incite somebody to action very quick-wearing or gummed, influence the operate as normal of reciprocating saw; Cause reciprocating saw to lose efficacy, finally influence the service life of reciprocating saw.
The utility model content
The purpose of the utility model is to provide the automatic fuelling device of reciprocating saw, because of no grease lubrication, causes easily and weares and teares or glue together between the reciprocating lever that can solve existing reciprocating saw effectively and the needle bearing ball bearing, influences the problem of reciprocating saw operate as normal.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The automatic fuelling device of reciprocating saw; Comprise reduction box loam cake, towing plate, reciprocating lever and ball bearing; It is characterized in that: be provided with oil storage tank in the reduction box loam cake, the top of oil storage tank is connected with the seal oil lid, and the bottom of oil storage tank is provided with first oilhole; First oilhole is corresponding towards the end face of towing plate one side with ball bearing, and the lubricating oil in the oil storage tank drips the surface in reciprocating lever through first oilhole.
Further, the bottom of oil storage tank also is provided with second oilhole, and second oilhole is positioned at the top of towing plate, and the lubricating oil in the oil storage tank drips the surface in towing plate through second oilhole.
Preferably, reciprocating lever and towing plate are structure as a whole.
Further, ball bearing is connected with sealing ring in a side of towing plate dorsad.
Preferably, sealing ring adopts the wool felt collar.
The utility model is owing to adopted technique scheme; Guarantee reciprocating lever in the course of the work; Oil storage tank carries out oily constantly to reciprocating lever and towing plate, needle bearing is lubricated in motion process at the lubricating oil on the towing plate, ball bearing is lubricated in motion process at the lubricating oil on the reciprocating lever; Effectively reduce wearing and tearing or gummed between reciprocating lever and needle bearing, the ball bearing, thereby increased the functional reliability and the service life of reciprocating saw greatly.The utility model is simple in structure, makes easyly, and cost is low, and is practical.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of the automatic fuelling device of the utility model reciprocating saw;
Fig. 2 is the structural representation of ball bearing in the utility model;
Fig. 3 is the structural representation of needle bearing in the utility model;
Fig. 4 is the I place structure enlarged diagram among Fig. 1;
Fig. 5 is the II place structure enlarged diagram among Fig. 1.
The specific embodiment
Extremely shown in Figure 5 like Fig. 1; Be the automatic fuelling device of the utility model reciprocating saw, comprise reduction box loam cake 1, towing plate 2, reciprocating lever 3 and ball bearing 4, be provided with oil storage tank 11 in the reduction box loam cake 1; The top of oil storage tank 11 is connected with seal oil lid 12; It is corresponding towards the end face of towing plate 2 one sides with ball bearing 4 that the bottom of oil storage tank 11 is provided with first oilhole, 13, the first oilholes 13, the lubricating oil in the oil storage tank 11 through 13 of first oilholes in the surface of reciprocating lever 3.The bottom of oil storage tank 11 also is provided with the top that second oilhole, 14, the second oilholes 14 are positioned at towing plate 2, the lubricating oil in the oil storage tank 11 through 14 of second oilholes in the surface of towing plate 2.Ball bearing 4 is connected with sealing ring in a side of towing plate 2 dorsad, and preferred sealing ring adopts wool felt collar 5.
In the oil storage tank 11 of reduction box loam cake 1, add butter, with oil cap 12 sealings.When reciprocating saw is worked; Needle bearing 6 drives towing plate 2 straight reciprocating motions, and towing plate 2 drives reciprocating lever 3 straight reciprocating motions, machine vibration; Internal temperature raises; Make the flowability of butter increase, oil storage tank 11 internal pressures increase, and drip in first oilhole 13 and second oilhole 14 of butter from reduction box loam cake 1.Sketch map when being illustrated in figure 1 as reciprocating lever 3 and being positioned at low order end, when reciprocating lever 3 beginnings during toward left movement, the oil droplet that drips in first oilhole 13 is in the surface of reciprocating lever 3; Through the motion of reciprocating lever 3, butter is added in the ball bearing 4, increase lubricating between reciprocating lever 3 and the ball bearing 4.Through the sealing function of wool felt collar 5, when reciprocating lever 3 spread out of ball bearing 4 toward right motion, butter was sealed in the ball bearing 4 by wool felt collar 5, prevents that effectively butter is from leaking into the outside simultaneously.The oil droplet that drips in second oilhole 14, adds to butter in the needle bearing 6 through the motion of towing plate 2 in the surface of towing plate 2, increases lubricating between towing plate 2 and the needle bearing 6.Through the lubrication at above-mentioned two places, thereby the service life and the functional reliability of reciprocating saw have been increased greatly.
More than be merely the specific embodiment of the utility model; But the technical characterictic of the utility model is not limited thereto; Any is the basis with the utility model; For realizing essentially identical technique effect, do the ground simple change, be equal to replacement or modification etc., all be covered by among the protection domain of the utility model.
