Based on the processing clamp 1, the clamping process of the glasses leg 2 is roughly as follows: placing the glasses legs 2 into the limiting holes and placing the glasses legs on the horizontal limiting surface, wherein one surface of each glasses leg 2 is attached to the vertical limiting surface; the pressing plate 14 is pressed down, and the glasses legs 2 are kept stable through the matching of the toothed plate 141, the horizontal limiting surface and the vertical limiting surface; driving the limiting strips 12 to move to the clamping positions of the limiting strips, and clamping the glasses legs 2; with platen 14 in its idle state.

EXAMPLE III

The embodiment of the invention provides an angle adjusting device 3, which can be used in the first embodiment and is used for adjusting the angle of a machining clamp 1.

As shown in fig. 7 to 10, the angle adjusting device 3 includes an adjusting base 31 and a level adjusting plate 32, the adjusting base 31 is installed on the working table 4, and the level adjusting plate 32 is installed on the adjusting base 31 through a level adjusting mechanism for adjusting an included angle between a plate surface and a horizontal plane.

Further, as shown in fig. 7-10, the angle adjusting device 3 further includes an angle adjusting plate 33, the angle adjusting plate 33 is rotatably stacked on the level adjusting plate 32 through a first rotating shaft 351, an eccentric second rotating shaft 352 is disposed on the level adjusting plate 32, a kidney-round adjusting hole is disposed on the angle adjusting plate 33, a diameter of the second rotating shaft 352 is the same as a width of the adjusting hole, and the second rotating shaft 352 is inserted into the adjusting hole.

The angle adjustment plate 33 is stacked on the level adjustment plate 32, that is, the plate surface of the angle adjustment plate 33 is parallel to the plate surface of the level adjustment plate 32, and generally, the lower plate surface of the angle adjustment plate 33 contacts with the upper plate surface of the level adjustment plate 32. The horizontal adjusting mechanism is used for adjusting the included angle between the plate surface of the horizontal adjusting plate 32 and the horizontal plane, and the included angle between the plate surface of the angle adjusting plate 33 and the horizontal plane is also adjusted.

It will be appreciated that the machining jig 1 is connected to the above-mentioned angle adjustment plate 33, for example, is mounted on the above-mentioned angle adjustment plate 33. In one embodiment, as shown in fig. 7-10, the angle adjusting plate 33 is provided with a positioning pin 38 for matching with the positioning pin 38 of the machining fixture 1, so that the machining fixture 1 can be positioned and placed on the angle adjusting plate 33, and the angle adjusting plate 33 can move to drive the machining fixture 1 to move together, thereby achieving the purposes of adjusting the levelness and the angle of the machining fixture 1. The positioning pins 38 are preferably provided in plural numbers, and more preferably, are arranged near each corner of the angle adjustment plate 33. The adjustment base 31 is attached to the table 4, and when the jig drive mechanism 6 is provided, the adjustment base 31 is preferably connected to the jig drive mechanism 6.

Alternatively, the level adjustment plate 32 and the angle adjustment plate 33 are the same in size, for example, both are rectangular plates and have the same length and width dimensions.

The first rotating shaft 351 is preferably located at the middle of the level adjustment plate 32, and in a structure in which the level adjustment plate 32 is a rectangular plate, for example, the first rotating shaft 351 passes through the center of the plate surface of the level adjustment plate 32. The first rotating shaft 351 is also preferably connected to a middle portion of the angle adjusting plate 33, and in a configuration in which the angle adjusting plate 33 is a rectangular plate, for example, the first rotating shaft 351 passes through the center of the plate surface of the angle adjusting plate 33. Obviously, the axis of the first rotating shaft 351 is perpendicular to the horizontal adjusting plate 32 and the angle adjusting plate 33, and the angle adjusting plate 33 can rotate relative to the first rotating shaft 351.

The second rotating shaft 352 is obviously disposed offset from the first rotating shaft 351; the second shaft 352 is an eccentric shaft, i.e. the rotation axis of the second shaft 352 does not coincide with the central axis of the second shaft 352. Optionally, the second rotating shaft 352 is of a sleeve type structure and includes a fixed shaft 3521 and a movable shaft 3522, wherein the fixed shaft 3521 is fixed on the level adjustment plate 32, a cylindrical through hole is formed in the movable shaft 3522, the diameter of the cylindrical through hole is the same as that of the fixed shaft 3521, and the central axis of the cylindrical through hole is deviated from the central axis of the movable shaft 3522, so that the movable shaft 3522 is sleeved on the fixed shaft 3521 and can rotate relative to the fixed shaft 3521; further preferably for cylindrical through hole for the screw hole, the outer wall of fixed axis body 3521 be the screw thread outer wall and with cylindrical through hole threaded connection, avoid activity axis body 3522 to appear the position dislocation after adjusting to target in place. Of course, it is also possible to provide the second rotating shaft 352 as an integrally formed structure and rotatable with respect to the level adjusting plate 32, and the specific structure is not illustrated here.

It is easy to understand that the waist-shaped adjusting hole comprises a rectangular section and two arc-shaped sections connected to two ends of the rectangular section, and the width of the adjusting hole is the width of the rectangular section; since the diameter of the second rotating shaft 352 (corresponding to the diameter of the fixed shaft 3521 for the structure including the fixed shaft 3521 and the movable shaft 3522) is the same as the width of the adjusting hole, after the second rotating shaft 352 is inserted into the adjusting hole, it is in contact with the wall of the rectangular section of the adjusting hole at both sides or in contact with the arc-shaped inner wall of the arc-shaped section of the adjusting hole.

The angle adjusting device 3 provided in this embodiment can adjust the included angle between the surface of the horizontal adjusting plate 32 and the horizontal plane through the horizontal adjusting mechanism, and can adjust the position of the angle adjusting plate 33 in multiple dimensions through the cooperation of the second rotating shaft 352 on the horizontal adjusting plate 32 and the waist-shaped adjusting hole on the angle adjusting plate 33, so as to adjust the angle of the loaded equipment, and is easy to operate; simple structure, reliable operation and low equipment cost.

When the angle adjusting device 3 is applied to the processing production of the glasses legs 2, particularly the laser marking production of the glasses legs 2 with higher process requirements, because the surfaces of the glasses legs 2 are provided with coatings, the coatings cannot be damaged during laser engraving, and the marked surfaces are smooth, have no obvious hand feeling and are clear, the position adjusting precision of the surfaces to be marked of the glasses legs 2 can be improved through the angle adjusting device 3, and the condition that the marking identification positions are inaccurate when the positions of the glasses legs 2 are deflected after being clamped is avoided; when a plurality of glasses legs 2 are processed at one time, the surfaces to be marked of the glasses legs 2 are positioned on the same horizontal plane, so that the marking efficiency and the marking quality are improved.

The rotation of the second rotating shaft 352 can be achieved manually or by an automatic control device, such as a conventional rotation driving device, which can be easily designed by those skilled in the art according to actual needs, and is not exemplified here. In the structure in which the second rotation shaft 352 includes the fixed shaft 3521 and the movable shaft 3522, in the manual operation mode, the top end of the movable shaft 3522 may be located above the top end of the fixed shaft 3521, and a slit or notch suitable for the operation of a tool such as a screwdriver may be formed in the top end of the movable shaft 3522.

Further optimizing the structure of the angle adjusting device 3, the angle adjusting device 3 is further provided with a locking unit for locking the angle adjusting plate 33 on the level adjusting plate 32 after the angle adjusting plate is adjusted in place, so as to ensure the continuity and stability of the angle adjusting in-place state. In one embodiment, as shown in fig. 7 and 9, the locking unit includes at least one locking bolt 36, at least one threaded locking hole is disposed on the level adjustment plate 32, the number of the locking bolts 36 is the same as that of the threaded locking holes, and the locking bolts 36 are disposed in a one-to-one correspondence manner, and each locking bolt 36 passes through the angle adjustment plate 33 and is screwed into the corresponding threaded locking hole; after the angle adjusting plate 33 is adjusted to the proper position by the second rotating shaft 352, the angle adjusting plate 33 and the level adjusting plate 32 can be fixed together by screwing the locking bolt 36 into the threaded locking hole.

Obviously, other forms of threaded fasteners such as screws are conventional alternatives to the lock bolt 36 described above and are also within the scope of the present application.

Further, the locking bolt 36 is preferably provided in plurality, and the threaded locking hole is correspondingly provided in plurality, so as to ensure stability and reliability of the locking structure of the angle adjusting plate 33.

As can be understood, since the locking bolt 36 needs to pass through the angle adjustment plate 33 and then be screwed into the corresponding threaded locking hole, a bolt through hole is correspondingly formed on the angle adjustment plate 33. Since the angle adjustment plate 33 tends to rotate relative to the level adjustment plate 32, the bolt passing hole may be an arc hole coaxial with the first rotating shaft 351 to ensure that the locking bolt 36 can be screwed with the threaded locking hole of the level adjustment plate 32 all the time.
