The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 to 5, the utility model discloses a tool angle adjusting device of precision positioning, including base 1, install scale plate 2 on base 1, rotate and connect in the angle adjustment plate 3 at the scale plate 2 back, it is preferred, angle adjustment plate 3 can directly realize rotating with scale plate 2 through rotation axis 31 and be connected, but not limited to this, can realize rotating through the mode of rotation axis cooperation axle sleeve or bearing and connect. The top of scale plate 2 has convex arc face and gear portion 22 that use the rotation axis of rotation axis 31 as the centre of a circle, angle adjusting plate 3 has the concave arc face of matching convex arc face and forms half enclosed construction to the top of scale plate 2, 3 internal rotations of angle adjusting plate are provided with an regulation pole 4 that has helix structure 41, helix structure 41 meshes with gear portion 22, angle adjusting plate 3's the back is used for fixed tool, scale plate 2 is equipped with scale 21 in the front that is close to convex arc face, angle adjusting plate 3 is equipped with the pointer 33 that is used for instructing scale 21 in the front that is close to concave arc face. This device adjusts the corner of tool through the cooperation of adjusting pole 4 and gear portion 22, and the concrete principle is: when the adjusting lever 4 is rotated, the gear portion 22 generates a rotational moment to the spiral line structure 41, so the angle adjusting plate 3 rotates around the rotating shaft 31, the jig mounted on the back of the angle adjusting plate 3 rotates together, and the indication of the rotation angle is accurately reflected by the scale 21 pointed by the pointer 33. The scale 21 has no problem of being shielded, thereby being convenient for adjustment. The angle adjusting plate 3 fixes the jig through the jig fixing hole 32 on the back surface, and the fixing area is large. Here, the scale 21 takes 1 ° as the minimum unit, but the minimum unit of the scale 21 may be less than 1 °, and the accuracy may be improved to below 1 °. The adjusting rod 4 may be a screw or a worm.
As shown in fig. 1, 3 and 4, the angle adjusting plate 3 is provided with an adjusting rod holder 5 at a non-adjusting end of the adjusting rod 4, the adjusting rod holder 5 has a shaft hole through which the adjusting rod 4 passes and a jack screw hole perpendicular to the shaft hole, and a jack screw 51 for jacking against the arc surface of the adjusting rod 4 is provided in the jack screw hole. During angle adjustment, the jackscrew 51 releases the adjusting rod 4 outwards; after the adjustment is completed, the jackscrew 51 is screwed to abut against the adjusting rod 4, and the adjusting rod 4 cannot be loosened to cause the change of the position of the jig.
As shown in fig. 1 to 4, the angle adjusting plate 3 is provided with a micrometer screw 6 at an adjusting end of the adjusting rod 4, the micrometer screw 6 includes a fixing sleeve 61 through which the adjusting rod 4 passes and a knob 62 fixed at the adjusting end of the adjusting rod 4, the knob 62 has scale marks at an edge close to the fixing sleeve 61, and the fixing sleeve 61 is provided with indicating lines matching the scale marks. When the knob 62 is rotated, on one hand, the angle of the knob relative to the fixed sleeve 61 changes, and on the other hand, the axial position of the knob relative to the fixed sleeve 61 changes, so that the reading can be amplified to be changed by the readings of the two, and the precision can be further improved to be below 1 degree.
As shown in fig. 2, the scale lines equally divide the edge 50 of the knob 62, the angle adjustment plate 3 rotates 1 ° relative to the scale plate 2 every two rotations of the knob 62, each rotation of the knob 62 corresponds to an arc on the indication line, and the outer end of the knob 62 is provided with a locking button 63 for preventing the knob 62 from rotating. So that the distance between adjacent arcs represents 0.5 deg., and the angle between adjacent graduations on the knob 62 represents 0.01 deg. on the graduated plate 2, so that the accuracy of the readings can be of the order of 0.01 deg.. At the time of reading, the locking button 63 is pressed first, so that the micrometer screw 6 cannot be loosened to cause deviation of the reading.
As shown in fig. 5 and 6, the angle adjusting plate 3 has an adjusting lever hole 34 through which the adjusting lever 4 passes, the middle of the adjusting lever hole 34 is perforated with a concave arc surface, the front edge of the gear part 22 has an arc-shaped groove 23, and the front of the concave arc surface has an arc-shaped protrusion 35 surrounding the arc-shaped groove 23. The adjustment lever 4 is thus geared with the gear portion 22 at the opening position of the adjustment lever hole 34; meanwhile, the arc-shaped protrusion 35 can be matched with the arc-shaped groove 23, so that the angle adjusting plate 3 has only rotational freedom relative to the scale plate 2 and does not move relatively in the axial direction of the rotating shaft 31, and the angle adjusting plate and the scale plate are prevented from loosening during adjustment.
As shown in fig. 1, two pointers 33 pointing to the scale 21 are provided on the concave arc surface, and the positions of the two pointers 33 are mirror-symmetrical with respect to a vertical plane on which the axis of the rotating shaft 31 is located. Therefore, no matter the angle adjusting plate 3 rotates forwards or backwards, a pointer 33 can point to the scale 21, so that the angle adjusting plate 3 has a larger adjusting range, and a user can read data conveniently.
As shown in fig. 1, the gear portion 22 is provided with a plurality of grooves 221 which are distributed at intervals along the convex arc surface and are matched with the helical line structure 41. The groove 221 can be cut into the convex arc surface for engagement with the adjustment lever 4. The groove 221 structure can also be replaced by a number of convex teeth protruding over a concave arc. As shown in fig. 1, 2 and 4, the base 1 is wider than the scale plate 2, and a plurality of supporting feet 13 are provided at the bottom of the base 1. The device can be laid on an uneven surface, and the overturning risk caused by unstable gravity center can be reduced.
As shown in fig. 1, 2 and 4, the upper surface of the base 1 is provided with a plurality of fixing grooves 11 matching with the width of the scale plate 2, each fixing groove 11 is provided with a plurality of fixing holes 12, and the bottom of the scale plate 2 is provided with threaded holes 24 for fixing screws in cooperation with the fixing holes 12. When the device is provided with different jigs, the gravity center of the whole body can be changed along the width direction of the base 1, and in order to avoid the loss of balance of the device, the scale plate 2 can be fixed in different fixing grooves 11, so that the gravity center always falls in the middle of the range of the plurality of supporting feet 13.
As shown in fig. 3 and 6, the back surface of the angle adjusting plate 3 is provided with a plurality of jig fixing holes 32 which are distributed in a rectangular shape. The jig is generally fixed by placing four corners on the angle adjusting plate 3, so the jig fixing holes 32 are generally rectangular. Therefore, the angle adjusting plate 3 can meet the fixing requirements of various jigs by drilling the jig fixing holes 32 with corresponding distances in advance.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
