Abstract
The invention relates to a testing device of a rolling cylinder liner comprising the cylinder liner, a fixture and a rolling wheel. The cylinder liner is provided with a supporting shoulder, the end part of the supporting shoulder is provided with a tool withdrawal groove, the fixture is used for fixing the cylinder liner, the rolling wheel rolls the tool withdrawal groove, one end of the fixture is provided with a step, the other end is provided with a screw thread, and the step end is provided with a counter. In the invention, the cylinder liner is not broken in the process of use, the life of a motor is prolonged, a lot of maintenance costs are saved, and therefore, comprehensive costs are reduced.
Description
Technical field
The present invention relates to the cylinder jacket proving installation.
Background technology
Cylinder jacket is the engine heart component, the water jacket wall of wet liner directly contacts with chilled water, be subjected to the alterante stress of connecting rod swing and reciprocating motion of the pistons in the course of the work, and wet liner there is stress at supporting shoulder relief groove place, so very easily rupture in wet liner supporting shoulder withdrawing place.Make at the supporting shoulder withdrawing place of wet liner to add compressive stress, this compressive stress can be offset a part of alterante stress in the course of the work, thereby can not ruptured in cylinder jacket supporting shoulder withdrawing place for this reason.Because wet liner supporting shoulder withdrawing place wants roll extrusion at the essential procedure that increases of production run, increases operating personnel and equipment, therefore can increase the cost of production.
Summary of the invention.
The technical problem to be solved in the present invention is: provide a kind of and apply compressive stress at cylinder jacket supporting shoulder place relief groove, make cylinder jacket offset a part, produce fracture hidden danger roll extrusion cylinder jacket proving installation thereby solved cylinder jacket supporting shoulder place in the course of work and alterante stress.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of roll extrusion cylinder jacket proving installation, comprise cylinder jacket, has the supporting shoulder on the cylinder jacket, supporting point of shoulder portion offers relief groove, also comprises anchor clamps that are used for fixing cylinder jacket and the rolling wheel that relief groove is carried out roll extrusion, and described anchor clamps one end has step, the other end has screw thread, and described step end is provided with counter.
According to another embodiment of the invention, roll extrusion cylinder jacket proving installation further comprise described counter comprise inductor and with corresponding the forming of inductor near switch.
According to another embodiment of the invention, roll extrusion cylinder jacket proving installation comprises that further described rolling wheel drives by hydraulic jack, and described hydraulic jack is connected by support with rolling wheel.
According to another embodiment of the invention, roll extrusion cylinder jacket proving installation comprises that further described cylinder jacket is connected with the anchor clamps clearance fit.
According to another embodiment of the invention, roll extrusion cylinder jacket proving installation further comprises away from described step end and is provided with the opening pad, by nut pad is fixedlyed connected with cylinder jacket.
The invention solves the defective that exists in the background technology, cylinder jacket can not rupture in the use of the present invention, and the life-span of engine is improved, and has saved a lot of maintenance costs, so integrated cost is to reduce.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Wherein: 1, cylinder jacket, 2, supporting shoulder, 3, relief groove, 4, anchor clamps, 41, step, 42, screw thread, 43, the opening pad, 44, nut, 5, rolling wheel, 6, counter, 61, inductor, 62, near switch, 7, hydraulic jack, 8, support.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of roll extrusion cylinder jacket proving installation, comprise cylinder jacket 1, has supporting shoulder 2 on the cylinder jacket 1, supporting shoulder 2 ends offer relief groove 3, also comprise anchor clamps 4 that are used for fixing cylinder jacket 1 and the rolling wheel 5 that relief groove 3 is carried out roll extrusion, and described anchor clamps 4 one ends have step 41, the other end has screw thread 42, and described step 41 ends are provided with counter 6.The preferred described rolling wheel 5 of the present invention drives by hydraulic jack 7, and described hydraulic jack 7 is connected by support 8 with rolling wheel 5, thereby can guarantee that rolling wheel 5 has level of freedom, is convenient to rolling wheel 5 roll extrusion relief grooves 3.
Wherein, described counter 6 comprise inductor 61 and with corresponding the forming of inductor 61 near switch 62, come test fixture 4 rotational speeies by inductor 61, and rotating cycle.In order smoothly cylinder jacket 1 to be taken off from anchor clamps 4, the preferred cylinder jacket 1 of the present invention is connected with anchor clamps 4 clearance fit.For fixed air cylinder sleeve 1, the present invention preferably is provided with opening pad 43 away from described step 41 ends, by nut 44 opening pad 43 is fixedlyed connected with cylinder jacket 1, thereby cylinder jacket 1 is fixed on the anchor clamps 4.
The invention process process is as follows:
At first, the cylinder jacket 1 that has relief groove 3 is installed on the anchor clamps 4, and by anchor clamps 4 driven rotary, the speed of rotation can be set according to designing requirement; Then, start start button, rolling wheel 5 is done feed motion under the effect of hydraulic jack 7 hydraulic couplings, rolling wheel 5 clamping cylinders cover 1 supporting shoulder 2 lower surface relief grooves 3 places during work; Then, anchor clamps 4 begin rotation, and anchor clamps 4 are rotated in place the back by sending signal near switch 62; At last, and then rolling wheel 5 begins to release, and anchor clamps 4 rotations stop.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
