Description
Technical Field
The invention relates to a tension measuring device of a contact measuring head.
Background
At present, the position or size of a component in a machine tool or a measuring machine can be measured generally by using both optical measurement (non-contact measurement) and mechanical measurement.
Optical measurements using lasers, whose beams impinge on the table when the drill bit is mounted on the chuck of a drilling machine or the tool is mounted on the spindle of a milling machine via a chuck type tool holder, can be used to locate the edge of a workpiece using a probing method. The spot of the laser will show the actual position of the spindle centre line relative to the workpiece, clamp or holder. This visible datum point allows the operator to locate the spindle at a particular location point, the center point of the workpiece, and the center of the hole or the center of the scribe line. This may also enable them to correct the vise, set the inclination of the milling head and the centre indexer and rotary table.
Although the optical measurement method reduces the debugging and clamping time of some workpieces, the optical parts are extremely expensive, and the high-precision polishing and other treatment are required. More importantly, the optical measurement is susceptible to ambient light and stray light, and the processing of noise signals is difficult. On the other hand, it is difficult to perform treatments such as concave holes on the boundary line and discontinuous shape treatments by optical measurement.
In view of this, in the case of processing non-continuous or more precise measurement objects, the prior art generally uses a contact-type detection device for measurement.
For example, patent document (publication No. CN 103403491B) discloses a contact probe for checking the position or size of a machine tool or measuring machine, comprising a support frame having a protective casing and a support and positioning area, a movable armset housed locally in the protective casing and comprising an arm carrying a feeler adapted to contact a component to be checked, an advancing device arranged between the support frame and the movable armset for pushing the movable armset against the support and positioning area, a restraining and positioning system located between the movable armset and the support frame at the support and positioning area, and a processing device having a laminar piezoelectric sensor connected to the support frame and adapted to provide a force signal in response to a force applied to the feeler, and to process said force signal, to compare it with a threshold value, and provides a contact signal indicative of contact between the stylus and the part to be inspected.
However, in the contact probe of the above-mentioned document, when a fine measurement object such as a bearing inner ring after grinding is measured, the measured contact force greatly affects the accuracy and quality of the bearing, and a large tension causes a flaw on a product and a small tension affects a machining dimension.
In addition, because the circular measuring head is used, certain abrasion can be generated due to contact force in the using process, and further mechanical errors are generated. Therefore, with this type of detector, a regular correction of the tension of the measuring head is required.
As can be seen from the above patent documents, the measurement of the tension of the measuring head is substantially performed by measuring the tension of the measuring head rigidly coupled to the elastic member or the pressure-sensitive member in the measuring head. Conventionally, in a measurement of a tension in an axial direction of a probe plus a spring, a jig is generally provided in the axial direction to apply a pressure in the axial direction. For example, chinese patent document CN 206017325U.
However, as described above, the important cause of the tension error of the measuring head is that the measuring head having a circular or regular shape is worn, and if the measuring head and the spring are pressed only in the axial direction, the part that is in contact with the measuring head forms an indefinite angle or gap due to the shape of the measuring head, and the measurement accuracy is greatly affected.

FIG. 2 is a schematic structural diagram of a tension measuring device of a contact measuring head according to a preferred embodiment of the present invention.
Detailed Description
The present invention will be more clearly and completely described in the following description of preferred embodiments, taken in conjunction with the accompanying drawings.
Fig. 1 is a schematic view of a contact measurement head according to this embodiment. As shown in fig. 1, the contact type measuring head 200 of the present embodiment includes a rod-shaped measuring head 201 and an elastic member or a pressure-sensitive member connected to the measuring head 201, and the measuring head 201 presses the elastic member 203 to a cylindrical housing 202.
In this embodiment, as can be seen from fig. 1, the tip of the gauge head 201 is circular, and the circular tip is easily worn during use, so that the measured tension value is not necessarily the maximum tension value when the tension measurement is performed in the axial direction.
On the other hand, in the present embodiment, the gauge head 201 is connected to the elastic member 203 inside the housing 202, but in some embodiments, the elastic member 203 is not provided, and force transmission is performed by a hydraulic pressure or the like. Some contact measuring heads even directly contact the measuring head to the pressure-sensitive part. These are all applicable to the present invention.
Fig. 2 is a schematic structural diagram of a tension measuring device of the contact measuring head of the present embodiment. As shown in fig. 2, the tension measuring apparatus 100 of the contact measuring head according to the present invention includes: a tension measuring part which comprises a measuring terminal 25 which is abutted with one end of the measuring head 201 far away from the elastic component or the pressure sensitive component and is used for measuring the tension of the contact measuring head 200; a fixing portion 11 that fixes the housing 202; a screw rod 12, the screw rod 12 being perpendicular to the axial direction of the contact measuring head 200, and one end being fixed to the fixing portion 11; the adjusting seat of the screw rod 12, the screw rod 12 condition seat includes a screw member 17 in screw connection with the screw rod 12, the screw member 17 is movably fixed to a bottom plate 30.
Specifically, the fixing portion 11 is provided with a through hole for receiving a portion of the housing 202 of the contact measuring head 200, and then is fixed by a bolt. The screw 12 is also fixed to the fixing portion 11 by a bolt. Before the measurement, the fixing portion 11 may be fixed to the contact measuring head 200 and then slid on the screw rod 12.
Of course, in other embodiments, the fixing portion is not necessarily a sheet metal as in this embodiment, and a clamp may be directly used to clamp the housing portion of the contact measuring head.
The tension measuring section includes a tension gauge 22, and the gauge 201 is inserted through a hole in the measuring terminal 25 and abuts against an elastic body of the tension gauge 22. That is, the measurement of the tension is done by a tensiometer. When the gauge 201 abuts on the elastic body of the tension gauge 22, the tip of the gauge 201 is a worn circle, and the direction of the tension of the gauge head is not necessarily in the axial direction of the gauge 201, and therefore, the measurement reading directly in the axial direction is generally too small.
In addition, the screw member 17 is cylindrical, and a screw hole in threaded connection with the screw rod 12 is arranged on the axis of the screw member 17; the screw rod adjusting seat also comprises a position adjusting mechanism which is partially fixed on the bottom plate 30 and used for adjusting the horizontal position of the screw member 17.
That is, the screw 17 is a cylindrical body provided with a screw hole into which the lead screw 12 is rotatably inserted. Since the screw 12 is fixed to the fixing portion 11, the screw 12 is slightly displaced in a direction perpendicular to the horizontal plane when the screw 17 is rotated. In this way, the stylus 201 is also rotated by a slight angle in a direction perpendicular to the horizontal plane.
When the screw 17 is rotated, the measuring head 201 and the contact measuring head 200 are continuously displaced, and at this time, the tension meter 22 continuously reads, and the maximum reading (or the reading within the proximity range of the maximum reading) is selected as the tension value of the contact measuring head.
Further, the above-mentioned effect can be enhanced by adjusting the horizontal position of the screw 17 by the above-mentioned position adjusting mechanism. Specifically, in the embodiment, the position adjusting mechanism comprises a stopper 14, a stopper 16, a positioning bolt 13 and a positioning bolt 15, wherein the stopper 14 and the stopper 16 are fixed on the bottom plate 30;
the positioning bolt 13 is threaded through the stopper 14 and abuts against the screw 17, so that the screw 17 is displaced in a direction parallel to the axial direction of the contact measurement head 200.
Accordingly, the positioning bolt 15 is screwed through the stopper 16 to abut against the screw 17, so that the screw 17 is displaced in a direction perpendicular to the axial direction of the contact measuring head 200. Of course, as shown in fig. 2, other stoppers may be provided at symmetrical positions of the stoppers 14 and 16 to facilitate adjustment.
Therefore, the angle of the measuring head 201 can be finely adjusted by more means, so that the adjustment is more convenient, and the measurement precision is further improved.
On the other hand, the measurement terminal 25 is fixed to a vertical rod 23 perpendicular to the bottom plate 30; one end of the vertical rod 23 is fixed to the base plate 30 by the vertical rod fixing seat 24.
The vertical rod holder 24 may be displaced on the base plate 30 in a direction parallel to the axial direction of the contact measuring head 200.
The vertical rod 23 serves to support the measuring terminal 25, and since the vertical rod 23 is closer to the stylus 201, the adjustment of the position of the vertical rod greatly affects the stylus and can be used as a rough adjustment, and can be generally applied to the adjustment of the touch type measuring head 200 to the horizontal.
The vertical stick is fixed to the base plate 30 by the vertical stick fixing base 24 and then can be adjusted to be displaced in the horizontal direction. Specifically, the method can be implemented by a bolt type structure or an eccentric wheel shaft and the like, and the implementation manners belong to conventional technical means in the field, and therefore, the detailed description is omitted.
Further, the vertical rod holder 24 is shaped to extend in a direction perpendicular to the axial direction of the contact measuring head 200, and forms an "L" shaped configuration together with the vertical rod 23. The measurement terminal 25 is provided with a tension adjustment knob 21 for adjusting an elastic body for measuring tension in the tension meter 22, and the tension adjustment knob 21 is selectively and finely adjusted to generate a reading of the tension meter 22.
The vertical rod holder 24 is formed in an "L" shape with respect to the vertical rod 23 to prevent the contact measuring head 200 from rotating around the axis of the contact measuring head 200 when the position of the contact measuring head 200 is adjusted. Because the tip portion of the probe, which is worn, is displaced in a manner not favorable for reading when the rotation occurs. In other words, in an ideal situation, the displacement of the contact measuring head according to the present embodiment of the present invention should be limited to a plane perpendicular to the horizontal direction and the axial direction of the contact measuring head (i.e., the X-axis, the Y-axis, and the Z-axis, but not including the rotation angle).
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
