Abstract
The utility model relates to a cylinder sleeve supporting shoulder pressure resistance limiting value detection device, which comprises a positioning sleeve, a support ring, a pressure plate and a pressure head, wherein the positioning sleeve is barrel-shaped; the upper edge of the positioning sleeve is propped against the support ring; a support ring annular step is arranged on the outer edge on the bottom surface of the support ring, and is in fit tolerance with the excircle of the positioning sleeve; and a pressure plate annular step is arranged on the circumference of the bottom surface of the pressure plate, and the pressure head presses and leans against the pressure plate. According to the utility model, the support ring is arranged on the positioning sleeve in a sleeving way, and is sleeved with a popping excircle step surface at the upper part of a cylinder sleeve to be detected, so that a relief groove at the root part of a supporting shoulder is just positioned on the support ring, the lower edge of the pressure plate leans against the upper edge of the cylinder sleeve, then the relief groove at the root part of the supporting shoulder is just positioned in a stress position through the pressure head and the pressure plate pushed by a pressing machine, the rolling effect of a certain batch is detected through a number of destruction tests, and then the quality of the cylinder sleeve in the certain batch is judged.
Description
Technical field
The utility model relates to the cylinder jacket field, especially relates to a kind of pick-up unit that detects cylinder jacket supporting shoulder compression resistance ultimate value.
Background technology
Cylinder jacket is one of vital part of engine, is in " heart " position of engine, and cylinder jacket and piston, cylinder head are formed airtight cylinder operation space jointly.The reliability of cylinder jacket directly determines the reliability of engine, and in the cylinder jacket failure mode, the fracture of supporting shoulder is the inefficacy of a danger close, and the lighter damages piston and piston ring, and weight person's cylinder body, cylinder cap and connecting rod all damage.In order to prevent the fracture of cylinder jacket supporting shoulder, staple product adopts roll extrusion supporting shoulder relief groove technology, and after the roll extrusion of cylinder jacket supporting shoulder relief groove circular arc, its surface metal is compacted, and its molecules align improves its mechanical property more closely in order.
As shown in Figure 2, the top of cylinder jacket 7 is provided with cylinder jacket supporting shoulder relief groove 8, if cylinder jacket supporting shoulder ruptures, its fracture line 9 tilt, and fracture line 9 lower ends are at cylinder jacket supporting shoulder relief groove 8 places.
But after the roll extrusion; Lean on conventional cubing can't judge the roll extrusion effect, can adopt X ray stress ga(u)ge or X-ray diffractometer to detect the size of the residual-stress value at roll extrusion position, thereby judge the roll extrusion effect indirectly; But the own instrument of X ray stress ga(u)ge or X-ray diffractometer is expensive; And X-radiation is harmful, and it is high to detect cost, also very unfavorable to workman's health.
The utility model content
The purpose of the utility model is to provide the pick-up unit of the withstand voltage limit of a kind of easy detection cylinder jacket supporting shoulder relief groove.
The technical scheme of the utility model is:
Cylinder jacket supporting shoulder compression resistance ultimate value pick-up unit; Comprise abutment sleeve, support ring, platen and pressure head; Said abutment sleeve is tubular; Abutment sleeve upper edge and support ring are abutted against, and outer, said support ring bottom surface is provided with the support ring ring-shaped step, are tolerance fit between said support ring ring-shaped step and the abutment sleeve cylindrical; Said platen bottom surface circumference is provided with the platen ring-shaped step, and pressure head is pressed against on the platen.
Also comprise positioning seat, said abutment sleeve lower edge is provided with the step with the corresponding clamping of positioning seat.
The utility model is sheathed support ring on abutment sleeve, and the cylindrical step surface that the top of cylinder jacket to be detected is protruded is enclosed within on the support ring, makes supporting shoulder root relief groove just in time be positioned on the support ring; The lower edge of platen leans against the upper edge of cylinder jacket, promotes pressure head and platen through pressing machine then, makes supporting shoulder root relief groove just in time be in stressed place; Detect a certain batch roll extrusion effect through destructive test several times, and then judge the cylinder jacket quality of this batch, though need to destroy cylinder jacket; But with respect to harmful ray detection; The utility model is harmless, and the checkout equipment cost of required use is low, and it is also low to detect cost.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of cylinder jacket.
Embodiment
As shown in Figure 1, the utility model comprises positioning seat 1, abutment sleeve 2, support ring 3 and platen 5 and pressure head 6.Positioning seat 1 is dish-type, and abutment sleeve 2 is the tubular of upper and lower opening, and abutment sleeve 2 lower ends are connected with positioning seat 1 through seam, and the two adopts tolerance fit.The lower edge of support ring 3 is connected to the upper edge of abutment sleeve 2 through seam, and the two also is to adopt tolerance fit.The interior circular diameter of support ring 3 and cylinder jacket to be detected are suitable at this place's external diameter, and the tolerance fit between the two is F8/h7.Along the circumferential direction be locked with some bolts 4 between abutment sleeve 2, the support ring 3.The downside of platen 5 is provided with the step surface with cylinder jacket 7 upper edge shape adaptation, and the tolerance fit between the two is H7/f6, and platen 5 upper surfaces are the plane, and pressure head 6 is pressed in platen 5 upper surfaces.
During detection, the positioning seat 1 of this device is installed on the hydraulic pressure machine worktable, puts into support ring 3 to cylinder jacket 7 gently; Cover platen 5 then, pressure head 6 is connected with the claw of rampiston lower end, and hydraulic pump starts; The promotion piston moves down; When pressure head 6 with after platen 5 contacts, pressure boost gradually is up to breaking cylinder jacket 7.As shown in Figure 2, fracture location 9 is for playing cylinder jacket 7 inwalls from supporting shoulder root relief groove 8, and the direction of fracture is tilted to, and just can judge the quality of roll extrusion effect through the pressure size of test.The maximum pressure that bears when cylinder jacket breaks is called supporting shoulder compression resistance ultimate value.
Claims (2)
1. compression resistance ultimate value pick-up unit is takeed in the cylinder jacket supporting; It is characterized in that: comprise abutment sleeve, support ring, platen and pressure head; Said abutment sleeve is tubular; Abutment sleeve upper edge and support ring are abutted against, and outer, said support ring bottom surface is provided with the support ring ring-shaped step, are tolerance fit between said support ring ring-shaped step and the abutment sleeve cylindrical; Said platen bottom surface circumference is provided with the platen ring-shaped step, and pressure head is pressed against on the platen.
2. cylinder jacket supporting shoulder compression resistance ultimate value pick-up unit according to claim 1, it is characterized in that: also comprise positioning seat, said abutment sleeve lower edge is provided with the step with the corresponding clamping of positioning seat.
