1. can not carry out on-the-spot test, can not test and install or the inconvenient workpiece that moves;
2. the large-scale workpiece that can not test size surpasses A/F between anvil block and the pressure head;
3. complex structure, cost is higher;
4. operation easier is bigger, needs tester's operation of specialty.
The utility model content:
In order to address the above problem, the utility model provides a kind of Portable Brinell hardness tester, and it not only can test the hardness of common workpiece, can also carry out scene test fast to hardness bigger, can't workpiece clamping and that installed and fixed.
To achieve these goals, the utility model is taked following design proposal:
A kind of Portable Brinell hardness tester is characterized in that: it comprises the pressure head pillar, cuts off and pressure head; Axial location in pressure head pillar bottom is provided with the pressure head hole, is provided with the intersect vertical axis position of pressure head pillar and cuts off the hole; Pressure head hole and cut off the hole and connect; Cut off to be arranged at and cut off in the hole, pressure head is arranged in the pressure head hole, and the upper surface of pressure head contacts with the middle part that cuts off, and the lower end of pressure head is exposed by the pressure head hole.
The described top that cuts off the hole is provided with cleaning eye, cleaning eye and pressure head hole and cut off the hole and connect.
The utility model also comprises the sleeve that is used to hold the pressure head pillar, and the outer wall of pressure head pillar is provided with supporting surface, and the shape of sleeve lining is propped up the corresponding supporting surface that is provided with of column outer wall shape with pressure head.
Described pressure head pillar is a right cylinder that has the circular conical surface projection, and pressure head pillar top is a sphere; To prop up the column outer wall shape corresponding with pressure head, and sleeve is the cylinder that an inwall has circular conical surface.
Described cutting off is right cylinder, with the pressure head pillar cut off the corresponding setting in hole.
Described pressure head is a right cylinder that is arranged in the pressure head hole, pressure head pillar bottom, and its upper surface is the plane, and the lower end is a sphere.
The sphere and the pressure head of described pressure head lower end are integrative-structures, or are embedded in the steel ball or the sintered carbide ball of pressure head lower end.
The utility model also comprises the augmentor that applies test power to pressure head pillar top, the dynamic augmentor that is made of hammer or plexor member; Or the static augmentor that constitutes by the gap frame that has screw rod and spanner.
The advantage of the Portable Brinell hardness tester that the utility model provides is simple, conveniently to carry, needn't take a sample, can be used for on-the-spot test more greatly, heavier, hardness that inconvenience is moved, workpiece has been installed.The Portable Brinell hardness tester that the utility model provides can be by dynamic reinforcing, also can be by static afterburning.Can only contact sample when dynamically afterburning and simultaneously finish test, need not anvil block, so be specially adapted to test the hardness of large-scale workpiece that can't clamping.
Description of drawings:
Fig. 1 is the utility model Portable Brinell hardness tester structure cut-open view;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1, pressure head pillar, 2, sleeve, 3, cleaning eye, 4, cut off the hole, 5, cut off, 6, the pressure head hole, 7, pressure head, 8, sample.
Describe the utility model in detail below in conjunction with drawings and Examples.
Embodiment:
The utility model Portable Brinell hardness tester structure will cut off 5 and put into and cut off hole 4 as shown in Figure 1 and Figure 2, pressure head 7 be put into pressure head hole 6, and pressure head pillar 1 is put into sleeve 2.Pressure head 7 lower ends in the pressure head pillar 1 contact with sample 8 surfaces, pressure head 7 upper ends with cut off 5 and contact, and provide support for whole pressure head pillar 1 by cutting off 5, pressure head pillar 1 is suspended in the sleeve 2, the circular conical surface of pressure head pillar 1 outer wall is higher than the circular conical surface of sleeve 2 inwalls and leaves the space.
When carrying out hardness test, the Portable Brinell hardness tester that the utility model is provided is placed on the sample 8, and pressure head pillar 1 top is vertically applied test pressure.Test power is delivered to and cuts off 5 by cutting off hole 4, is delivered to pressure head 7 by cutting off 5 again, makes lower end pressing in sample 8 surfaces of pressure head 7 form impressions.When test power reaches when cutting off 5 fracture threshold value, cut off 5 and cut off 4 inside upper part edges, hole and pressure head 7 upper end-face edges and shear and fragment into three sections.The test power that is applied on the pressure head 7 was cancelled in the moments that cut off 5 fractures, like this, cut off 5 fracture and can guarantee to be applied to the test power that test power on the pressure head 7 reaches and be no more than regulation.5 two ends that cut off of fracture are stayed and are cut off in the hole 4, and the stage casing is moved in the complete retraction pressure head hole 6 on the pressure head 7 relative pressure head pillars 1 by in the jacking cleaning eye 3.When cutting off for 5 whens fracture, pressure head 7 is also cancelled by 5 supports that provide for pressure head pillar 1 are provided, and pressure head pillar 1 integral body moves down, and its circular conical surface is fallen on the circular conical surface of sleeve 2.Sleeve 2 provides support for pressure head pillar 1, guarantees that its lower end do not pound the surface of dropping on sample 8.
