Abstract
The utility model discloses a speed-regulating connecting rod used for a single-cylinder diesel engine, which comprises a rod body (3). The rod body (3) is made of a steel plate by the punching process. A first supporting arm (4) provided with a through hole (1) and a second supporting arm (5) provided with a through hole (2) are arranged at one end of the rod body (3). A third supporting arm (6) is arranged at the other end of rod body (3). The first supporting arm (4) and the second supporting arm (5) are normally intersected, and the third supporting arm (6) and the first supporting arm (4) are arranged in parallel to each other. The speed-regulating connecting rod further comprises a screw rod (7) capable of being connected with a speed-regulating handle, wherein the screw rod (7) is fixedly connected with the third supporting arm (6). The speed-regulating connecting rod has the advantages of light weight, good quality, easy fabrication and low manufacturing cost, and provides the condition for the reduction in weight and cost of the single-cylinder diesel engine.
Description
Technical field
The utility model relates to a kind of speed governing connecting rod of single cylinder diesel, belongs to the diesel engine manufacturing technology.
Background technique
Speed governing connecting rod described in the utility model, an end that is mounted on the gear chamber cover is connected with governor lever by extension spring, and the structural member that its other end is connected with the speed governing handle.Drive of the displacement of speed governing handle by manpower, the aperture of regulating throttle, and the adjustment of realization diesel powered output shaft rotating speed along the set arc chute of gear chamber cover.
Existing described speed governing connecting rod is an ironcasting.This ironcasting speed governing connecting rod, not only its organization of commodity supply day is becoming tight, and its Heavy Weight, the processing technology complexity, preparation cost is higher, and quality also is difficult to guarantee that its functional reliability is also relatively poor relatively.
Summary of the invention
The utility model aims to provide a kind of speed governing connecting rod by the stamping forming single cylinder diesel of steel plate, to overcome the existing many deficiencies of prior art ironcasting speed governing connecting rod.
The utility model realizes that the technological scheme of its purpose is:
A kind of speed governing connecting rod of single cylinder diesel comprises being provided with the screwing through hole that is connected with gear chamber cover with screw, and with the body of rod of the through hole that is used for being connected with the adjusting screw of governor lever extension spring, its innovative point is:
A, the described body of rod, be that the one end has first support arm that is provided with described through hole and second support arm that is provided with described through hole, and its other end have the 3rd support arm, and first support arm and second support arm are just crossing mutually, and the 3rd support arm parallels the punching of the steel plate structural member of layout with first support arm;
B, also comprise the double-screw bolt that can be connected with the speed governing handle; Described double-screw bolt is fixedlyed connected with the 3rd support arm.
Can understand by above given technological scheme, the utility model is because it adopts the 3mm steel plate, by blanking and together with punch forming of described through hole, thereby simplified processing technology, alleviated weight, reduced cost of production, guaranteed quality, improve functional reliability, beautified moulding, realized its purpose that will realize.
The utility model is also advocated fixedlying connected of described screw and the 3rd support arm, is welding or riveted joint.With further simplification technology, to eliminate prior art and adopt screw-nut to connect, the inevitable connection that produces of institute is become flexible, and influences its functional reliability.
The utility model also advocates to be provided with recess on the body of rod between first support arm and second support arm.Further alleviating weight of the present utility model, and its work flexibility and reliability more.
After technique scheme was implemented, characteristics such as materials tissue that the utility model had is convenient, and in light weight, processing technology is simple and easy, and cost of production is relatively low, and quality and functional reliability are good, and be handsome in appearance were self-evident.
Description of drawings
Fig. 1 is the blanking unfolding state figure of a kind of embodiment of the utility model; 9 is the pilot hole of the reduced diameter section of the double-screw bolt 7 when with double-screw bolt 7 riveted joints shown in the figure;
Fig. 2 is the plan view of a kind of embodiment of the present utility model;
Fig. 3 is the plan view of Fig. 2; Double-screw bolt shown in the figure 7 is with the 3rd support arm 6 riveted joint of the body of rod 1, and an end of described double-screw bolt 7 has a reduced diameter section, and the 3rd support arm 6 is provided with the through hole equipped with the reduced diameter section of double-screw bolt 7; In the specific implementation, this through hole can with the through hole 1 of first support arm 4 and the through hole 2 of second support arm 5, punching molding together.
Embodiment
A kind of typical embodiment is shown in accompanying drawing 2,3.
A kind of speed governing connecting rod of single cylinder diesel, comprise and be provided with the through hole 1 that is connected with gear chamber cover with screw, the body of rod 3 with the through hole 2 that is used for being connected with the adjusting screw of governor lever extension spring, the described body of rod 3, be that the one end has first support arm 4 that is provided with described through hole 1 and second support arm 5 that is provided with described through hole 2, and its other end have the 3rd support arm 6, and first support arm 4 and second support arm 5 are just crossing mutually, and the 3rd support arm 6 parallels the punching of the steel plate structural member of layout with first support arm 4; Also comprise the double-screw bolt 7 that can be connected with the speed governing handle; Described double-screw bolt 7 and 6 riveted joints of the 3rd support arm.On the body of rod 3 between first support arm 4 and second support arm 5, be provided with recess 8.
Except that above-mentioned embodiment was described, double-screw bolt 7 of the present utility model can be welded to connect with the 3rd support arm 6.In order to guarantee that form and position tolerance realizes correct assembly relation, the welding of mould location is adopted in the welding of suggestion double-screw bolt 7 and the 3rd support arm 6.
The concise and to the point description of production process of the present utility model is: adopt the thick steel plate of 3mm, earlier through blanking and punching (as shown in Figure 1), again through punch forming of mould.
The utility model first sample is very gratifying in machine effect on probation.For the loss of weight of single cylinder diesel has been created condition with reducing cost.
