Abstract
The utility model discloses an auxiliary device for quickly detecting the hardness. The device consists of a supporting sleeve and a cushion block, wherein the supporting sleeve is a hollow cylinder; the cushion block is a cylindrical sheet with a circular hole in the center; the outer diameter of the cushion block is slightly larger than that of the supporting sleeve; the supporting sleeve is vertically arranged on a workbench of a hardness meter; the cushion block is put on the end face of the supporting sleeve; and a circular rod at the lower end of a movable claw is inserted into an inner hole of the cushion block. The auxiliary device for quickly detecting the hardness of the movable claw can directly test the hardness value of a starting claw under the condition that three pawls of the starting claw are not used for cutting; the diameter of the outer circle of the supporting surface of the device at least needs to be equal to that of a disk part of the starting claw; the whole circumferential surface of the disk part of the starting claw is attached to the plane of the upper part of the cushion block, so that the lower end of a workpiece is enlarged to achieve a steadily supporting effect; therefore, the hardness of the starting claw to be tested can be quickly and accurately detected; and the hardness test operation is convenient and simple.
Description
Technical field
The utility model relates to the material hardness detection range, particularly the servicing unit of the similar 6QA starting dog of a kind of favourable fast detecting hardness.
Background technology
The starting dog that engine is used, as shown in Figure 1, when hardness test is carried out in its three pawl ends, because the end face at claw place is much bigger than the other end, the power that penetrator applies when beating hardness and lower end anchorage force produce a moment of flexure not on coaxial cable, make the workpiece unstability and topple over, therefore can't directly detect claw end face hardness everywhere at all, way before is to slice off 3 nail-presss, regrind make upper and lower surface parallel after, put the sclerometer workbench again and carry out hardness test.So not only will destroy workpiece and cause the waste loss, increase many time, human and material resources simultaneously, inspection cost greatly increases.
Summary of the invention
The utility model provides a kind of quick test start pawl hardness servicing unit, can effectively increase work efficiency, and reduces inspection cost, detects fast, and it is fast to change the detection parts, and the size specification conversion is many.
Technical solution of the present utility model is such, a kind of servicing unit of fast detecting hardness, comprise penetrator, starting dog, cushion block, support set, the sclerometer worktable, it is characterized in that support set (4) is bearing on the sclerometer worktable (5), cushion block (3) is installed on support set (4) top, starting dog (2) is installed on cushion block (3) top, starting dog (2) is penetrator (1) on the top, support set (4) is cylindrical, the middle part is hollow, cushion block (3) is the cylinder sheet, there is endoporus at the center, pore size has more than a kind of specification, the cushion block of different size is arranged more than (3) one, and starting dog (2) lower end cylinder inserts the endoporus of cushion block (3).
Support set (4) center hollows out wall thickness 2～12mm, and height is greater than the lower end round bar length of starting dog (2), and external diameter is bigger than the excircle of workpiece that detects.
The utility model advantage compared with prior art is, the servicing unit of the quick test start pawl of this kind hardness makes 3 pawls of starting dog to cut to grind the back just can directly test its hardness number, guaranteed that starting dog is not only quick but also accurate when tested for hardness, hardness test is convenient and simple for operation.

Fig. 1 is the structural representation that the implementation case hardness detects workpiece-6QA starting dog.
Fig. 2 is that the utility model hardness detects the servicing unit structural drawing.
Fig. 3 is that 6QA starting dog hardness of the present utility model detects servicing unit use synoptic diagram.
Among Fig. 1～Fig. 3, penetrator (1), starting dog (2), cushion block (3), support set (4), sclerometer worktable (5).
Embodiment
Most preferred embodiment of the present utility model is: at first, this device is made of support set and cushion block, as Fig. 2.Support set is the hollow cylindrical shape in a middle part, has the slice of cylinder of circular hole centered by the cushion block.The external diameter of cushion block can be a bit larger tham the external diameter of support set, and the interior Circularhole diameter of cushion block is a bit larger tham starting dog lower end round bar, when detecting starting dog, earlier hardness being detected servicing unit is put on the scleroscopic big bear dish, again the lower end round bar of starting dog was interted circular hole on the cushion block, starting dog chassis portion and cushion block are steadily fitted, be equivalent to like this starting dog lower end " increase ", workpiece also can be stood firm under sclerometer pressure, thereby can effectively accurately measure the hardness of upper surface fast.A kind of servicing unit of fast detecting hardness, comprise penetrator, starting dog, cushion block, support set, the sclerometer worktable, it is characterized in that support set (4) is bearing on the sclerometer worktable (5), cushion block (3) is installed on support set (4) top, starting dog (2) is installed on cushion block (3) top, starting dog (2) is penetrator (1) on the top, support set (4) is cylindrical, the middle part is hollow, cushion block (3) is the cylinder sheet, and there is endoporus at the center, and the aperture has more than a kind of specification, cushion block (3) has different size more than one, and starting dog (2) lower end cylinder inserts the endoporus of cushion block (3).
The detection of the claw hardness of the starting dog (see figure 1) of using with regard to engine illustrates embodiment of the present utility model below.At first cylinder iron or steel process as shown in Figure 2 support set and cushion block, the support set center hollows out, wall thickness is 2mm～12mm, highly is greater than the lower end round bar length of starting dog.The support set external diameter is bigger than the detection faces cylindrical of survey workpiece, for the hardness that adapts to the different size workpiece detects usefulness, can do the different cushion block of a series of internal orifice dimension, and the thickness of cushion block is 5～15mm, and external diameter can be identical with support set or big slightly.
The use of device was seen shown in Figure 3 when hardness detected, at first support set (4) is steadily placed vertically on scleroscopic worktable (5), size according to detection workpiece lower end, select the cushion block (3) of suitable diameter of bore to be placed on support set (4) end face, again the lower end round bar of starting dog (2) is interted endoporus into cushion block, guaranteeing that starting dog chassis portion puts is attached on the cushion block plane, move support set (4) then, make the point that will detect hardness be in the below of penetrator (1), at this moment can load and begin to detect hardness.
This hardness detects servicing unit and is not only applicable to starting dog, also is applicable to all parts greater than a header structure of similar starting dog, and be specially adapted to need be at the part of big end tested for hardness.Small end position size according to part to be measured is selected suitable cushion block for use, as long as the big end that is connected with small end is the plane, all can use this device.
