In order to facilitate multi-angle, reliable measurement of large-size parts using the reflective ball 200, the present application relates to an auxiliary measuring device for a reflective ball 200 of a laser tracker, see fig. 1 and 2, which is used for the reflective ball 200 and includes a clamping portion 100, a universal adjusting block 200 and a rod assembly 300.

The clamping portion 100 is used to clamp the outer sidewall of the reflective ball 700, and in some embodiments of the present application, the clamping portion 100 may be a clamp ring, where the clamp ring has an opening, and the opening is fastened by a fixing element to fasten the clamp ring and the reflective ball 700.

Specifically, referring to fig. 1 to 3, the snap ring has a first flange 110 and a second flange 120 at the opening, the first flange 110 and the second flange 120 are opposite and have threaded holes (not shown) respectively formed thereon, and the bolt 101 passes through the threaded holes of the first flange 110 and the second flange 120 to lock the opening.

The universal adjustment block 200 may be connected to the first flange 110 or the second flange 120.

The rod assembly 300 includes a plurality of rods that are connected in sequence along their length to form extension bars that enable long-range measurements of the part under test.

In some embodiments of the present application, referring to fig. 1, the lever assembly 300 includes a first lever portion 310, a second lever portion 320, and a third lever portion 330.

The first, second and third rod portions 310, 320 and 330 are connected to each other in sequence along their respective lengths to form an extension rod.

The universal adjusting block 200 is connected to one end of the first rod portion 310 in a universal rotation manner, and particularly a ball groove is formed at one end of the first rod portion 310, and the ball of the universal adjusting block 200 is rotated in the ball groove, so that the measuring angle of the reflective ball 700 can be adjusted when the ball of the universal adjusting block 200 is rotated.

Referring to fig. 2-4, the other end of the first stem 310 forms a first metal connection block 311, which in some embodiments of the present application is formed as a connection block with a boss, the first metal connection block 311 extending into one end of the second stem 320.

The second rod portion 320 is hollow and conductive, and is provided with a conductive elastic restoring member therein, and one end of the elastic restoring member is connected to the first metal connecting block 311.

An indication circuit is arranged in the third rod portion 330, a second metal connecting block 3311 is arranged at one end of the third rod portion 330, the second metal connecting block 3311 stretches into the other end of the second rod portion 320, and the other end of the elastic reset piece is connected with the second metal connecting block 3311.

Referring to fig. 4, one end of the indicating circuit is connected to the second metal connection block 3311, and the other end is connected to the second lever portion 320.

When the second metal connection block 3311 is in contact connection with the second rod portion 320, the indication circuit forms a closed loop, and the indication circuit will give out an indication at this time, otherwise, the indication circuit will not give out an indication.

In some embodiments of the present application, the second metal connection block 3311 is connected to the first metal connection block 311 through an elastic restoring member, and thus, when the first metal connection block 311 is connected to the second rod portion 320, the second metal connection block 3311 is connected to the second rod portion 320 in contact, and at this time, the indication circuit forms a closed loop.

When an operator holds the auxiliary measuring device and applies force to make the surface of the reflecting ball 200 closely adhere to the surface of the measured part, the force is transmitted to the elastic resetting piece through the first rod portion 310 and the first metal connecting block 311 thereon, so that the elastic resetting piece is subjected to, for example, lateral deformation pressure to drive the first metal connecting block 311 to continuously contact with the inner side wall of the second rod portion 320, at this time, the indication circuit forms a closed loop to send an indication,

when the operator removes the applied force or the applied force weakens until the first metal connection block 311 is out of contact with the inner side wall of the second lever portion 320, the indication circuit does not form a closed loop, and no indication is given.

When an operator sees the indication, the operator indicates that the currently operated reflecting ball 700 is tightly attached to the measured part, and measurement can be started; when the operator cannot see the indication, the surface of the reflective ball 700 is not tightly attached to the measured part, and at this time, if measurement is started, the problem of inaccurate measurement exists, so that the operator needs to adjust the angle of the reflective ball 700 to tightly attach the reflective ball 700 to the measured part, and the measurement accuracy and precision are improved.

In some embodiments of the present application, referring to fig. 2 and 3, the resilient return member is selected as a spring 400, one end of which is sleeved (e.g., welded) onto the first metal connection block 311, and the other end of which is sleeved (e.g., welded) onto the second metal connection block 3311.

The spring 400 has a high hardness, and when the auxiliary measuring device is not used, the spring 400 is at an initial position, and the spring 400 is not deformed, and a gap is formed between the first metal connection block 311 and the inner side wall of the second rod portion 320, that is, the first metal connection block 311 and the inner side wall of the second rod portion 320 are in non-contact connection.

In addition, since the hardness of the spring 400 is high in the present application, if the spring 400 is deformed to contact and connect the first metal connection block 311 with the inner sidewall of the second rod portion 320, a certain force needs to be applied by an operator, so that the reflective ball 700 can be ensured to reliably contact with the measured part.

When the force applied by the operator is insufficient, the spring 400 is deformed but not deformed yet, so that the first metal connecting block 311 is in contact with the inner side wall of the second rod portion 320, and the indication circuit does not give an indication at this time, and when the operator observes that no indication exists, the applied force is increased again, so that the reliable contact between the reflective ball 700 and the measured part is ensured.

In some embodiments of the present application, for ease of indication, referring to fig. 1, the third rod portion 330 includes a first rod 331, a second rod 332, and a third rod (not labeled) connected in sequence along the length, forming an extension rod.

The lengths of the first, second, and third bars 310, 320, 331, 332, and 332, respectively, as described above, may be flexibly set.

The indication circuit as described above includes the battery 500 and the indication unit 600, and the battery 500 is used to supply power to the indication unit 600 when the indication circuit is a closed loop, so that the indication unit 600 gives an indication.

The first lever 331 includes a circumferential outer sidewall that is conductive, and referring to fig. 2, 3 and 5, an accommodating space for accommodating the battery 500 is formed inside the first lever 331, and one end of the first lever 331 is provided with a connection terminal, which is the second metal connection block 3311 as described above, insulated from the circumferential outer sidewall by an insulating portion 3312.

Referring to fig. 3, one pole (e.g., positive electrode) of the battery 500 is connected to the second metal connection block 3311.

The second rod 332 is electrically conductive, and an accommodating space for accommodating the indication unit 600 is formed inside the second rod 332, one end 610 of the indication unit 600 is connected to the other pole (e.g., negative pole) of the battery 500, and the other end of the indication unit 600 is connected to the second rod 332.

As described above, the first lever 331, the second lever 332, and the third lever are connected to each other, and therefore, at least the circumferential outer side wall of the first lever 331 and the second lever 332 are in contact electrical connection.

Wherein it is necessary to ensure the safety of the measurement when the operator holds the auxiliary measuring device, the third lever is arranged to be non-conductive.

The second lever 320, the first lever 331, and the second lever 332 are in contact electrical connection when the second lever 320 and the third lever 330 are connected in sequence.

Therefore, in the auxiliary measuring device, referring to fig. 3, the first metal connection block 311, the spring 400, the second metal connection block 3311, the battery 500, the indicating unit 600, the second rod 332, the first rod 331, and the second rod 320 are electrically connected in this order, forming an electrical connection loop.

When the auxiliary measuring device is not used, the spring 400 is at the initial position, and the spring 400 is not deformed, and a gap is formed between the first metal connection block 311 and the inner sidewall of the second rod portion 320, that is, the first metal connection block 311 and the inner sidewall of the second rod portion 320 are not connected to each other, and at this time, the electrical connection circuit as described above cannot form a closed circuit, so that the battery 500 cannot supply power to the indication unit 600, and the indication unit 600 does not issue an indication.

When an operator applies a certain force to make the reflective ball 700 reliably contact with the measured part, the force deforms the spring 400, so that the first metal connection block 311 contacts with the inner side wall of the second rod portion 320, and the electrical connection loop forms a closed loop as described above, and at this time, the battery 500 provides the electrical energy for the indication unit 600, and the indication unit 600 gives an indication.

When the force applied by the operator is insufficient, the spring 400 is deformed but not deformed yet, so that the first metal connecting block 311 is in contact with the inner side wall of the second rod portion 320, at this time, the battery 500 cannot provide electric energy for the indicating unit 600, the indicating unit 600 does not give an indication, and when the operator observes that no indication exists, the applied force is increased again, so that reliable contact between the reflecting ball 700 and the measured part is ensured.

As described above, the indication circuit may be an audible indication circuit, a visual indication circuit, or an audible and visual indication circuit.

Correspondingly, when the indication circuit is an audio indication circuit, the corresponding indication unit 600 may be a buzzer, when the indication circuit is an optical indication circuit, the corresponding indication unit 600 may be an LED lamp, and when the indication circuit is an audio-optical indication circuit, the corresponding indication unit 600 may be a combination of the buzzer and the LED lamp.

The indication circuit described above may be placed outside the auxiliary measuring device, so long as the first metal connection block 311 and the inner wall of the second rod portion 320 can be brought into contact with each other when the reflective ball 700 and the measured component are in close contact with each other.

In order to facilitate the operator to observe the indication, when the indication unit 600 is a buzzer or a combination of a buzzer and an LED lamp, the second rod 332 provided with the indication unit 600 as described above may be provided to be transparent and have a sound penetrating hole so as to transmit the sound generated by the buzzer out through the sound penetrating hole, or the light generated by the LED lamp may be displayed to the operator through the transparent second rod 332.

When the indication unit 600 is an LED lamp, the second lever 332 provided with the indication unit 600 as described above may be provided to be transparent so that the light generated from the LED lamp is displayed to the operator through the transparent second lever 332.
