[0002] In order to improve the machining accuracy of CNC machine tools, an encoder is usually installed on the mechanical spindle of the CNC machine tool. The magnetic encoder has become the preferred encoder for the mechanical spindle because it can be directly installed on the mechanical spindle.

[0003] Since an appropriate reading gap needs to be left between the reading head and the magnetic ring of the magnetic encoder, the magnetic encoder is usually installed with the aid of an installation tool to eliminate the adjustment process of the reading gap. The existing installation tool includes a reading head mounting part and a magnetic ring mounting part. The magnetic ring mounting part is connected to the reading head mounting part and can rotate relative to the reading head mounting part. The reading head mounting part is mounted on the spindle box, the reading head is mounted on the reading head mounting part, the magnetic ring is mounted on the magnetic ring mounting part and fixedly connected to the mechanical spindle. The reading head mounting part and the magnetic ring mounting part locate the distance between the reading head and the magnetic ring, so that the magnetic ring and the reading head do not need to be adjusted and tested for the reading gap after installation.

[0004] The installation tool in the above solution can only assist in the installation of a magnetic encoder of one size. For magnetic encoders of different sizes, installation tools of different sizes need to be manufactured, which reduces the use value of the installation tool and is not conducive to the practical application of the installation tool. Summary of the invention

The multiple magnetic ring mounting seats are evenly arranged around the rotation axis of the rotating disk, and the sliding direction of the magnetic ring mounting seats is the direction close to or away from the rotation axis of the rotating disk; An adjustment assembly, comprising a first adjustment portion and a second adjustment portion; Among them, the first adjustment part is connected to all the magnetic ring mounting seats, the second adjustment part is connected between the first adjustment part and the reading head mounting seat, the first adjustment part is used to synchronously adjust the positions of all the magnetic ring mounting seats, the second adjustment part is used to synchronously adjust the position of the reading head mounting seat when the first adjustment part adjusts the magnetic ring mounting seat, and the second adjustment part is used to disconnect from the first adjustment part when the rotating disk rotates.

[0007] By adopting the above technical solution, the mounting block is installed on the spindle box, the rotating disk is mounted on the mechanical spindle, the first adjustment part adjusts the positions of multiple magnetic ring mounting seats, the second adjustment part synchronously adjusts the position of the reading head mounting seat, the magnetic rings are installed on the multiple magnetic ring mounting seats, and the reading head is installed on the reading head mounting seat. Under the linkage adjustment of the first adjustment part and the second adjustment part, the reading gap between the reading head and the magnetic ring can automatically meet the reading requirements, so that without adjusting the reading gap, the installation tooling can enable magnetic encoders of different sizes to be installed on the mechanical spindle, thereby improving the actual use value of the installation tooling.

[0009] By adopting the above technical solution, multiple bidirectional telescopic rods are connected to multiple magnetic ring mounting seats to form a whole. Moving the bidirectional telescopic rods can make all the magnetic ring mounting seats slide synchronously and make the sliding strokes of all the magnetic ring mounting seats consistent. On the one hand, the adjustment efficiency of the magnetic ring mounting seats is improved, and on the other hand, the adjustment error of the magnetic ring mounting seats is reduced.

[0014] Optionally, an elastic card adapted to the adjustment rod is provided on the reading head mounting seat, and the elastic card is used to elastically clamp the adjustment rod.

[0015] By adopting the above technical solution, the adjusting rod is clamped in the elastic clamp, which makes it easy to put the adjusting rod back in place and makes it difficult for the adjusting rod to affect the rotation of the rotating disk.

The sliding direction of the sliding hole guide sliding rod is a direction close to or away from the rotation axis of the rotating disk, and the sliding direction of the adjusting hole guide sliding rod is set at an angle to the sliding direction of the sliding hole guide sliding rod.

The pawl is rotatably connected to the rotating disk, and the torsion spring is arranged between the pawl and the rotating disk. The torsion spring is used to drive the pawl head of the pawl to be engaged in one of the tooth grooves of the ratchet.

[0019] By adopting the above technical solution, the torsion spring drives the pawl to limit the one-way rotation of the ratchet, making it difficult for the ratchet to rotate in the opposite direction after the sliding rod drives the sliding rod to slide toward the rotation axis of the rotating disk, so that the position of the magnetic ring mounting seat after abutting against the mechanical main shaft can be automatically fixed.

[0020] Optionally, a return spring is arranged in the slide hole, and the return spring is used to drive the slide rod to slide away from the rotation axis of the rotating disk.

[0021] By adopting the above technical solution, when it is necessary to release the fixed state of the magnetic ring mounting seat, the pawl is rotated to release the restriction of the pawl on the ratchet wheel. The reset spring can automatically drive the slide rod to reset and slide through the elastic force, so that the magnetic ring mounting seat can be easily reset automatically.

[0022] Optionally, a clamping block is connected to the magnetic ring mounting seat, and the clamping block is used to fit into a clamping slot provided on the mechanical spindle.

[0033] Furthermore, a fixing bolt 31 is threadedly penetrated on the reading head mounting seat 3, and the bolt head of the fixing bolt 31 is a hexagon socket bolt head. The fixing bolt 31 is pressed against the mounting block 1 to fix the position of the reading head mounting seat 3 on the mounting block 1.

A clamping block 41 is fixedly connected to the magnetic ring mounting seat 4, and the clamping block 41 is used to fit into the clamping slot provided on the mechanical spindle, so that the connection between the magnetic ring and the mechanical spindle is more stable after the magnetic ring is mounted on the magnetic ring mounting seat 4.

[0036] Reference Figure 1 and Figure 3 The adjustment assembly 5 includes a first adjustment part 51, a second adjustment part 52 and an adjustment drive part 53. The first adjustment part 51 is connected to the six magnetic ring mounting seats 4, and is used to adjust the positions of the six magnetic ring mounting seats 4 to meet the installation requirements of magnetic rings of different sizes. The second adjustment part 52 is connected between the first adjustment part 51 and the reading head mounting seat 3. The second adjustment part 52 is used to synchronously adjust the position of the reading head mounting seat 3 when the first adjustment part 51 adjusts the magnetic ring mounting seat 4, and is used to disconnect from the first adjustment part 51 when the rotating disk 2 rotates, so that the reading gap between the reading head and the magnetic ring does not need to be adjusted, and the magnetic ring can rotate relative to the reading head. The adjustment drive part 53 is connected to the first adjustment part 51, and is used to drive the first adjustment part 51 to synchronously adjust the positions of the six magnetic ring mounting seats 4.

[0037] During installation, the mounting block 1 is mounted on the spindle box, the rotating disk 2 is sleeved on the mechanical spindle, the adjusting drive part 53 drives the first adjusting part 51 to adjust the positions of the six magnetic ring mounting seats 4, the second adjusting part 52 synchronously adjusts the position of the reading head mounting seat 3, the magnetic ring is mounted on the six second screw holes 43, and the reading head is mounted on the two first screw holes 33. Under the linkage adjustment of the first adjusting part 51 and the second adjusting part 52, the reading gap between the reading head and the magnetic ring can automatically meet the reading requirements, so that the installation tooling can enable magnetic encoders of different sizes to be installed on the mechanical spindle without adjusting the reading gap, thereby improving the actual use value of the installation tooling.

[0038] Reference Figure 1 In the present application, the first adjustment part 51 includes a two-way telescopic rod 511, and six two-way telescopic rods 511 are provided. The six two-way telescopic rods 511 are respectively located between two adjacent magnetic ring mounting seats 4. The two movable ends of the two-way telescopic rod 511 are respectively fixedly connected to the two magnetic ring mounting seats 4 corresponding to themselves. Moving the two-way telescopic rod 511 can make the six magnetic ring mounting seats 4 slide synchronously.

[0039] Reference Figure 4 The second adjustment part 52 includes an adjustment rod 521, and the two ends of the adjustment rod 521 are respectively fixedly connected with a first connecting ring 522 and a second connecting ring 524, the first connecting ring 522 is sleeved with a first connecting column 523, the first connecting column 523 is fixedly connected to the reading head mounting base 3, the second connecting ring 524 is sleeved with a second connecting column 525, and the second connecting column 525 is fixedly connected to the rod body of one of the two-way telescopic rods 511.

[0040] Furthermore, the first connecting ring 522 is connected to the first connecting column 523 in the form of a cylindrical sleeve pair, and the second connecting ring 524 is connected to the second connecting column 525 in a sliding manner along the central axis direction of the second connecting column 525 .

[0041] When the first connecting ring 522 and the first connecting column 523 are in a sleeved state, and when the second connecting ring 524 and the second connecting column 525 are in a sleeved state, the adjusting rod 521 realizes the connection between the bidirectional telescopic rod 511 and the reading head mounting seat 3. On the one hand, the reading head mounting seat 3 and the magnetic ring mounting seat 4 can be synchronously adjusted in position. On the other hand, the distance between the reading head mounting seat 3 and the magnetic ring mounting seat 4 is limited so that the reading gap does not need to be adjusted.

[0042] Reference Figure 4Furthermore, an elastic card 526 adapted to the adjustment rod 521 is fixedly provided on the reading head mounting seat 3, and the elastic card 526 is used to elastically clamp the adjustment rod 521. The second connecting ring 524 is slid out along the central axis direction of the second connecting column 525, so that the second connecting ring 524 and the second connecting column 525 can be in a disengaged state, so that the connection relationship between the reading head mounting seat 3 and the two-way telescopic rod 511 is easy to release, and the adjustment rod 521 is swung so that the adjustment rod 521 is clamped in the elastic card 526, so that the adjustment rod 521 can be easily put back.

[0043] Reference Figure 1 and Figure 3 The adjusting driving part 53 comprises an adjusting disk, which is rotatably connected to a side of the rotating disk 2 away from the magnetic ring mounting seat 4. The adjusting disk is in a circular ring shape and is used to be sleeved on the mechanical main shaft.

Under the guiding effect of the slide hole 21 and the adjustment hole 5311, rotating the adjustment disk can drive the slide bar 512 to slide in a direction close to or away from the axis of the rotating disk 2, so that the six two-way telescopic rods 511 can be convenient for synchronously driving the six magnetic ring mounting seats 4 to adjust their positions.

[0045] Reference Figure 3 and Figure 5 Furthermore, the adjustment disk is a ratchet 531, and the adjustment driving unit 53 further includes a pawl 532 and a torsion spring 533. The pawl 532 is rotatably connected to the rotating disk 2, and the torsion spring 533 is fixed between the pawl 532 and the rotating disk 2. The torsion spring 533 is used to drive the pawl head of the pawl 532 to be clamped in one of the tooth grooves of the ratchet 531. The torsion spring 533 drives the pawl 532 to limit the unidirectional rotation of the ratchet 531, so that the ratchet 531 drives the slide bar 512 to slide toward the axis of the rotating disk 2 and is difficult to rotate in the opposite direction, so that the position of the magnetic ring mounting seat 4 after abutting against the mechanical main shaft can be automatically fixed.

[0046] Furthermore, a shift block 5312 is fixedly provided on the ratchet 531, and the shift block 5312 is used to shift the ratchet 531, so that the rotation of the ratchet 531 is more convenient; a knob 5321 is fixedly connected to the pawl 532, and the central axis of the knob 5321 coincides with the rotation axis of the pawl 532. The pawl 532 is rotated using the knob 5321, so that the rotation of the pawl 532 is more convenient.

The return spring 513 is used to drive the slide rod 512 to slide away from the axis of the rotating disk 2. When it is necessary to release the fixed state of the magnetic ring mounting seat 4, the knob 5321 is rotated to release the restriction of the pawl 532 on the ratchet 531. The return spring 513 can automatically drive the slide rod 512 to return and slide through the elastic force, so that the magnetic ring mounting seat 4 is easy to automatically reset.

[0048] When making adjustments, the dial block 5312 is turned to rotate the ratchet 531, the ratchet 531 drives the slide bar 512 to slide, the slide bar 512 drives the two-way telescopic rod 511 to move, the two-way telescopic rod 511 drives the magnetic ring mounting seat 4 to slide, and the reading head mounting seat 3 slides along with the two-way telescopic rod 511 under the pulling action of the adjustment rod 521, so that the magnetic ring mounting seat 4 and the reading head mounting seat 3 can be adjusted synchronously, so that the magnetic ring mounting seat 4 can install magnetic rings of different sizes without adjusting the reading gap.
