Description
Technical Field
The utility model belongs to the technical field of check out test set, concretely relates to a device that is used for auxiliary measurement to have metal axle hardness on flange limit.
Background
At present, with the rapid development of the metal material industry, the research on the hardness of the metal is more and more important. Hardness refers to the ability of a material to locally resist the pressure of a hard object, such as its surface, and is an indicator of how hard or soft various materials are compared. In the production process of the bonding wire, different kinds of metal shafts are used, including different sizes of the intermediate shaft and the finished shaft. In the production process of the bonding wire, a metal shaft is needed in each process of material preparation and finished products, the quality of the metal shaft is particularly important, various aspects such as the surface, the performance and the like of the finished product of the bonding wire can be influenced, and the detection of the hardness of the metal shaft is an important basis for the qualification of the bonding wire after the bonding wire is put into a factory.
At present, although a corresponding hardness tester is used for measuring hardness, due to the particularity of the structure (cambered surface with a flange edge) of the metal shaft, the metal shaft cannot be directly placed on a test table of the hardness tester for direct measurement, and a tool is needed for auxiliary measurement.
Disclosure of Invention
To the not enough of above-mentioned prior art existence, the utility model provides a device that is used for the auxiliary measurement to have the metal axle hardness on flange limit.
The utility model discloses a realize through following technical scheme.
The device for assisting in measuring the hardness of the metal shaft with the flange edge is characterized by comprising a tray, a clamp and a horizontal measuring device; the side wall of the tray is provided with two opposite through holes; the clamp comprises two clamping jaws which are oppositely arranged in the tray, each clamping jaw is connected with one end of a connecting rod, and the other end of each connecting rod penetrates through the through hole of the tray and is connected with the adjusting button; the level measurement device is arranged at the upper end of the tray.
The device according to the above, characterized in that the gripping surface of the gripping jaw is arc-shaped.
According to above-mentioned device, characterized in that, the clamping face of clamping jaw is attached with the rubber pad.
According to the device, the through holes of the tray are bolt holes, and the outer wall of the connecting rod is provided with threads.
The apparatus of the above, wherein the leveling device is a level.
The beneficial effects of the utility model are that, the utility model provides a device that is used for the auxiliary measurement to have the metal axle hardness on flange limit, the measurement that can be more convenient has the hardness of the metal axle on flange limit. Due to the diversity of the sizes and the types of the shafts, the difficulty of measurement is increased, but the utility model can realize the auxiliary measurement of the metal shafts with different sizes by adjusting the adjusting buttons at the two ends; furthermore, the utility model discloses have level measurement device, can guarantee the accuracy of measuring numerical value, be with the rubber pad on the clamping face of clamping jaw, can protect the surface of metal axle better.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in FIG. 1, the device for auxiliary measurement of the hardness of the metal shaft with the flange edge comprises a tray 1, a clamp and a horizontal measuring device 2; the tray comprises a horizontal base plate and a side wall, the base plate and the side wall are matched to form a cavity structure with an opening at the top, the tray is used for placing a shaft to be measured, the bottom of the tray requires high levelness to ensure the accurate value of measurement, and the side wall of the tray is provided with two through holes which are opposite in position, namely a first through hole and a second through hole; the clamp comprises a first clamping jaw, a second clamping jaw, a first connecting rod, a second connecting rod, a first adjusting button and a second adjusting button, the two clamping jaws are oppositely arranged in the tray and used for clamping a shaft to be measured, the clamping surfaces of the two clamping jaws are arc-shaped, rubber pads are adhered to the clamping surfaces of the two clamping jaws, the surface of a metal shaft can be better protected, wherein, the first clamping jaw 3 is connected with one end of a first connecting rod 4, the other end of the first connecting rod 4 penetrates through a first through hole of the tray to be connected with a first adjusting button 5 arranged outside the tray, the second clamping jaw 3 'is connected with one end of a second connecting rod 4', the other end of the second connecting rod 4 'penetrates through a second through hole of the tray to be connected with a second adjusting button 5' arranged outside the tray, the distance between the two clamping jaws is adjusted by rotating the two adjusting buttons to clamp shafts with different sizes in a matching manner for hardness measurement, and the adjusting buttons are square blocks; level measurement device 2 sets up in the upper end of tray for the levelness of device when detecting the measurement, level measurement device is the spirit level, through level measurement device's cooperation, completion auxiliary measuring that can be better. Furthermore, two through holes of the tray are bolt holes, the outer walls of the two connecting rods are provided with threads, and the threads of the connecting rods are matched with the threads in the bolt holes of the tray.
During the use, will wait to measure the axle earlier and put tray 1 in, adjust two clamping jaws through two knobs of rotation and press from both sides tightly waiting to measure the axle, then place whole device on the sclerometer test platform, whether the bubble of the above-mentioned spirit level of observation device is located the levelness of intermediate position with the definite device, and the back of finishing the adjustment can carry out the hardness test.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention. It should be noted that other modifications and equivalents may be made by those skilled in the art in light of the teachings of the present disclosure to achieve the same purpose, and should be construed as within the scope of the present disclosure.
