DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a work mounting apparatus according to the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a side view showing a partial cross section of a moving table equipped with a work mounting device of the present invention, and FIG. 2 is a view taken in the direction of arrow A in FIG. In the figure, reference numeral 10 indicates a moving table, which can be moved forward and backward by a drive source (not shown) via three linear motion bearings on three rails 14 arranged in parallel on a base 12 at predetermined intervals. The table 16 is guided and supported, and a tilt block 18 fixed on the table 16 and having its upper surface tilted at a predetermined angle. A work mounting device 22 for mounting and supporting a work 20 is provided on the upper surface of the tilt block 18. ing. In this case, the shape of the work to be attached to the mounting device is, for example, as shown in FIGS. 3 to 4, an inclined shaft 26 inclined at a predetermined angle is implanted on the upper surface of a plate-shaped substrate 24 formed in a different shape. Vertically through the two pins 28, 30 and project this vertically
Flanges 28a and 30a having substantially the same diameter are formed on the two pins projecting downward.

When this type of work 20 is mounted on the tilt block 18, the tilt angle of the tilt block 18 is determined so that the tilt axis 26 is vertical. When the work is fixed by the mounting device 22 provided on the tilt block 18, the work 20 on the tilt block 18 is accurately positioned at the measurement position (not shown) by the movement of the moving table 10 by the action of the actuator (not shown). The tilt axis 26 of the positioned work 20 measures two points at each of the upper and lower sides of the outer circumference (two points at different angles of 90 ° on the same plane), and the measured values are calculated in the control device to obtain the tilt axis. The angle and position of is determined and compared with a reference value to determine the quality of the work.

In this case, the mounting device 22 provided on the inclined block 18 is constructed as follows. On the inclined block 18, two pins 28 and 30 projecting from the lower surface of the work 20 have a width corresponding to the outer diameter of a flange formed on each pin so as to guide and support the two pins in series in a predetermined linear range in series. A guide base 34 including a pair of rectangular cross-section blocks 34a, 34b, and 34c forming the guide groove 32.
Is attached, and an abutment block 36 having a V groove 35 is attached to an end of the guide groove 32. The groove width of the guide groove 32 in the vicinity of the contact block 36 is formed so that the upper portions of the facing surfaces thereof protrude from each other to be narrow, and the outer diameter portion of the two pins 28, 30 between the bottom portion of the substrate 24 of the work 20 and the flange. The locking portions 32a and 32b for guiding the are formed [see (a) of FIG. 4].

Further, one block 34c of the guide groove 32 is provided behind the pair of blocks constituting the guide groove 32.
Is provided by the actuator 33 so as to advance and retreat in a direction orthogonal to the guide direction of the guide groove 32. When the moving block 34c moves backward, the guide groove 32 expands and the work 20 dropped from the part is further moved. A through discharge hole 38 for discharging to the outside is formed in the inclined block 18 (see FIG. 1). In addition, the movable plate 40 is provided on the upper surface of the inclined block 18 near the contact block 36 and the actuator 4
It is supported by 2 (for example, a pneumatic cylinder) so as to be able to move back and forth along the guide groove 32.

As shown in FIG. 3, this moving plate 40
Is a notch recess 44 that can store the work 20 on the tip side surface.
Is formed and one of the two surfaces (actuator side) of the cutout recess 44 that are orthogonal to the movement axis of the movement plate 40 and that face each other (actuator side) is moved by the forward movement of the actuator 42.
A protrusion 46 is formed as a pressing portion for pressing the side surface of the substrate 24 of 0, and the substrate 2 of the work 20 is moved backward by the actuator 42 when the pressing is released on the side surface facing this.
An engaging portion 48 that engages with the four side surfaces is formed. An actuator 50 is attached to the upper surface of the inclined block 18 in the vicinity of the contact block 36 perpendicularly to this surface via a stand 52. The upper surface of the substrate 24 is pressed and held (see FIG. 1).

The mounting device thus constructed operates as follows. That is, FIG. 3 is a partially enlarged view of the work clamp operation explanatory view of the view taken along the arrow A of FIG. 1, in which (a) shows the state before and after the work is clamped, and (b) shows It is a figure which shows the clamped state of a workpiece | work. First, with the moving plate 40 in the retracted position, the moving plate 40 is moved from the notch recess 44 to
The pins 28, 30 of the book on the outer periphery of these flanges in the guide groove 3
Insert it in 2 to constrain the posture of the deformed work in a certain direction. In this state, when the actuator 42 is operated to move the moving plate 40 forward, the work 20 is cut into the notch recess 4
4, the side surfaces of the substrate 24 are pressed by the protrusions 46 provided inside 4 to move the two pins along the guide groove 32, and when the work 20 is further advanced, the pins 28 and 30 of the substrate 2 are moved.
4 The outer diameter between the bottom surface and the flange is the engaging portion 32 of the guide groove 32.
It is locked to a and 32b.

When the moving plate 40 reaches the moving end, of the two pins provided on the substrate 24 of the work 20, the pin 28 at the tip is brought into contact with the V groove 35 formed in the contact block 36 to be positioned. At the same time, the side surface of the substrate of the work 20 is brought into contact with the protrusion 46 of the moving plate 40, and the work can be laterally held. Further, the work 20 has its substrate 24
The upper surface of is pressed by the pressing element 54 and is securely clamped. Then, the work 20 mounted on the mounting device on the tilt block is accurately positioned by positioning the tilt shaft 26 of the work 20 at the measurement position by the movement of the moving table 16, and a predetermined measurement is performed.

After this, the movable table 16 returns to the original position again, and when the clamp is released, the movable plate 40 is retracted by the actuator 42, and the end of the work 20 is notched into the concave portion 4
4 is moved to a predetermined position by being locked to the locking portion 48 of No. 4, one moving block forming the guide groove 32 is moved to 34c.
Is moved backward by the actuator 33 to open the guide groove 32, the work 20 for which measurement has been completed is discharged to the outside from this portion through the through discharge hole 38 of the inclined block 18.

As described above, since the moving plate for mounting and discharging the work only by the reciprocating motion is formed in a thin plate shape, the shape of the notch recess 44 of the moving plate 40 is limited to the shape of the work described above. Without changing the shape of other work, it can be easily designed and manufactured according to its shape, as long as it has a part where the bottom surface of the work is guided by the guide groove, and it can be used for other purposes. The range can be extended.
