It should be noted that: like reference numerals denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
In order to understand the actual situation of stress deformation of a machine tool (such as a gear hobbing machine and a small upright of a gear grinding machine), accuracy of test data needs to be guaranteed, and external interference is reduced, so that a sensor needs to be mounted on a stable tool, and the stability of the tool needs to be guaranteed by the tool which also needs to be mounted on a stable base. The absolute deformation testing tool (hereinafter referred to as a testing tool) of the machine tool disclosed by the utility model takes a drilling machine as a base, and the tool can meet the absolute deformation testing of machine tools with different heights and different depths.
Fig. 1 is a schematic structural diagram of a machine tool absolute deformation testing tool based on a drilling machine according to an embodiment of the present utility model. As shown in fig. 1, the absolute deformation test fixture of the machine tool with the drilling machine as a base comprises a drilling machine 1 and a test fixture 100 fixed on the drilling machine 1. In use, the drill press 1 may be placed on a flat bottom surface and the test fixture 100 secured to the drill press 1 by the connection plate 2 (e.g., secured to the drill press 1 by bolting) on a skid plate. Fig. 2 is a schematic structural diagram of the test fixture 100. As shown in fig. 2, the test fixture 100 further includes a first strip-shaped flat plate 3, a second strip-shaped flat plate 4, a first support rod 5, a second support rod 6, a first displacement sensor and a second displacement sensor.
In some embodiments, the first strip-shaped flat plate 3 and the second strip-shaped flat plate 4 are arranged one above the other, and can be connected and fixed to the connecting plate 2 by using threaded holes arranged on the two.
One end of the first strip plate 3 includes two or more (e.g., 2, 3, 4, 5, 6, etc.) first threaded holes. The first screw holes are arranged along the length direction of the first strip-shaped flat plate 3. In some embodiments, the first threaded holes are equally spaced. In some embodiments, the first threaded holes are non-equally spaced. In use, a suitable first threaded hole may be selected for connection with the connection plate 2, depending on the depth of the machine tool to be measured. The other end of the first flat bar 3 (i.e., the end far from the first screw hole) is connected to the first support bar 5. The first support rod 5 is provided with a first displacement sensor.
One end of the second strip plate 4 includes two or more (e.g., 2, 3, 4, 5, 6, etc.) threaded holes. The second screw holes are arranged along the length direction of the first strip-shaped flat plate 3. In some embodiments, the second threaded holes are equally spaced. In some embodiments, the second threaded holes are non-equally spaced. In use, a suitable second threaded hole may be selected for connection with the connection plate 2, depending on the depth of the machine tool to be measured. The other end of the second flat bar 4 (i.e., the end remote from the second screw hole) is connected to the second support bar 6. The second support bar 6 is provided with a second displacement sensor.
In some embodiments, the number of first support bars is 1 to 2 and the number of second support bars is 1 to 2. For example, the first strip plate 3 is connected to only one first support bar 5, and the second strip plate 4 is also connected to only one second support bar 6. For another example, two first support bars 5 may be provided on the first strip-shaped flat plate 3, and two second support bars 6 may be provided on the second strip-shaped flat plate 4. In fig. 2, only a case where each bar-shaped flat plate is connected to two support bars is shown, which is only exemplary and not intended to limit the present utility model.
Each support bar (including the first support bar 5 and the second support bar 6) may also be provided with 1 to 5 displacement sensors 20, respectively (only one displacement sensor 20 is shown in fig. 2 for simplicity). Therefore, for each deformation test, there are at least 2 displacement sensors 20 to obtain the deformation data of the machine tool, so that the accuracy of the deformation data of the machine tool can be satisfied.
In some embodiments, the angle between the first displacement sensor and the first support bar 5 is adjustable, and the height of the first displacement sensor on the first support bar 5 is also adjustable. In some embodiments, the angle between the second displacement sensor and the second support bar 6 is adjustable, and the height of the first displacement sensor on the second support bar 6 is also adjustable. In some embodiments, the included angle between the first strip-shaped flat plate 3 and the second strip-shaped flat plate 4 is also adjustable, and the position of the displacement sensor connected to the test fixture can be changed by adjusting the included angle between the first strip-shaped flat plate 3 and the second strip-shaped flat plate 4. By providing the displacement sensor 20 with adjustable positions (including height and angle), the deformation of the components of each angle and height in the machine tool can be detected, thereby enabling a more accurate grasp of the deformation condition of the machine tool.
In some embodiments, the connection between the first strip panel 3 and the first support bar 5 and the connection between the second strip panel 4 and the second support bar 6 may be non-detachable, such as by welding. In some embodiments, the connection between the first strip plate 3 and the first support bar 5 and the connection between the second strip plate 4 and the second support bar 6 may be detachable, for example by a threaded connection, by a snap connection, by a hinge connection, etc. For example, screw holes may be provided at the ends of the first and second flat bar 3 and 4 to which the support bars are connected, and then the first and second support bars 5 and 6 may be screwed into the screw holes to be connected.
When the height of the first support bar 5 and/or the second support bar 6 cannot meet the deformation test of the machine tool having a high height, other extension devices (for example, the support bar extension base 10 shown in fig. 2) may be further added between the first bar-shaped flat plate 3 and the first support bar 5 and between the second bar-shaped flat plate 4 and the second support bar 6 to enable the sensors located on the first support bar 5 and the second support bar 6 to detect the deformation of the machine tool having a high height. It should be noted that, in fig. 2, the support rod extension base 10 is only shown below one support rod 5, which is for simplicity and not limiting the present utility model, and in practical use, the support rod extension base 10 may be further connected below each first support rod 5 and each second support rod 6. In some embodiments, the support rod extension base 10 has threaded holes at both ends, one end of which can be connected to the strip-shaped flat plates (e.g., the first strip-shaped flat plate 3, the second strip-shaped flat plate 4) by means of threaded connection, and the other end of which is connected to the support rods (e.g., the first support rod 5, the second support rod 6) by means of threaded connection.
The test fixture disclosed by the utility model has a simple structure, and some parts (such as the first strip-shaped flat plate 3, the second strip-shaped flat plate 4, the first support rod 5, the second support rod 6, the first displacement sensor and the second displacement sensor) can be detached and adjusted, and the support rod lengthening base 10 can be added, so that the absolute deformation test of machine tools with different heights and different depths can be met, and the application range is wide.
The materials of the first flat bar 3, the second flat bar 4, the first support bar 5, and the second support bar 6 used in the present utility model may be any rigid materials. The use of rigid materials further ensures the stability of the test fixture 100 and also allows for more accurate deformation data to be measured.
