The following describes the operation of an alignment device and system with a digital display according to an embodiment of the present application with reference to fig. 1 to 5. It is to be understood that the following description is exemplary only and is not intended to limit the scope of the present application.

In this embodiment, the alignment means comprises an alignment jig, as shown in fig. 1-5. The alignment jig comprises a first jig 1, a connecting portion 2 and a second jig 3 which are sequentially connected in the height direction. The first clamp 1, the connecting portion 2 and the second clamp 3 are all cylindrical, and the outer diameters of the first clamp 1 and the second clamp 3 are larger than the outer diameter of the connecting portion 2. The interior of the alignment jig is provided with a cavity communicating from the first jig 1 to the second jig 3. The vertical direction in fig. 1 is defined as the height direction, and the axial direction of the alignment jig is parallel to the height direction.

The alignment system may further comprise an equipment platform for carrying the alignment device and an equipment ram for gripping the part and moving the part to align with a tooling axis in the equipment platform when the alignment system is in use, the position of the equipment ram being normally adjusted to be alignable with the equipment platform. The alignment system is used for calibrating the position of the equipment platform or the position of the equipment pressure head before or during the use of the alignment system.

In order to further improve the alignment accuracy and to facilitate the operator to observe the positional offset of the tooling shaft or the equipment ram for adjustment, the alignment device further comprises at least one displacement detection sensor 4 and a digital display 6. In this embodiment, the number of the displacement detection sensors 4 is at least four. The displacement detection sensor 4 comprises a mounting part 42 and a probe 41, the mounting part 42 is fixed on the outer wall of the alignment fixture, the probe 41 at least partially enters the inside of the cavity, and the probe 41 can detect the position offset of the tool shaft or the equipment pressure head when moving in the cavity. The digital display 6 is connected to the displacement detection sensor 4, and can display detection data of the displacement detection sensor 4 in real time. When the alignment device is used for aligning the equipment platform and the equipment pressure head, a worker can conveniently adjust the displacement of the equipment platform or the equipment pressure head by referring to the display data of the digital display 6, the alignment precision of the equipment platform and the equipment pressure head is ensured, and the working efficiency of the alignment operation is improved. As shown in fig. 5, the alignment fixture further includes a sliding groove 9 and a shifting block 8 disposed inside the sliding groove 9, the shifting block 8 is coupled with the sensor bracket 5 on which the displacement detection sensor 4 is mounted, and may be connected by a link mechanism or other transmission mechanism, when the shifting block 5 is located at a first portion (e.g., a first end) of the sliding groove 9, the probe 41 protrudes into the cavity of the connection portion 2, and when the shifting block 5 is located at a second portion (e.g., a second end) of the sliding groove 9, the probe 41 is retracted toward the outside in a radial direction with respect to the connection portion 2 without blocking the tool shaft or the equipment ram from entering.

When the alignment system is used to align a tooling shaft on an equipment platform with an equipment ram, there are mainly two scenarios: first scene: the dial 8 is moved to the second position of the slide groove 9, and the probe 41 of the displacement sensor 4 is retracted. The digital display 6 displacement information is cleared. The elastic collet 31 of the second clamp 3 is sleeved on the tool shaft of the equipment platform, and the elastic collet 31 is locked. The equipment pressure head is manually or automatically moved downwards to enter the first clamp 1, the shifting block 8 is shifted to the first position of the sliding groove 9, the probe 41 of the displacement detection sensor 4 extends out of the cavity, the probe 41 is abutted against the outer wall of the equipment pressure head, the display values of all directions on the digital display 6 are observed, and the equipment pressure head is correspondingly adjusted according to the display values and the suggested adjustment values until 4 directions reach zero positions. The second scenario: the dial 8 is moved to the second position of the slide groove 9, and the probe 41 of the displacement sensor 4 is retracted. The digital display 6 displacement information is cleared. The elastic collet 31 of the second clamp 3 is sleeved into the device press head and locks the collet chuck. The fixture shaft of the equipment platform is inserted into the first fixture 1, the shifting block 8 is shifted to the first part of the sliding groove 9, the probe 41 of the displacement detection sensor 4 extends out of the cavity, the probe 41 is abutted against the outer wall of the fixture shaft, the display values of all directions on the digital display 6 are observed, and corresponding adjustment is carried out on the equipment platform according to the display values and the recommended adjustment values. Until 4 directions reach zero.

In this embodiment, the alignment device further comprises a display bracket 7, and one side of the digital display 6 is fixed to the outer wall of the connection part 2 through the display bracket 7, so that the digital display 6 and the alignment jig form a single unit, and the digital display 6 and the alignment jig can be integrally packaged, transported and moved, and the alignment device has good portability. The display bracket 7 and the alignment fixture can also be detachably connected, and the digital display 6 and the alignment fixture are separately placed during packaging and transportation, and then assembled during use. The connection line between the displacement detection sensor 4 and the digital display 6 may be disposed inside the display bracket 7, or disposed outside the display bracket 7, so as to ensure the connection stability between the digital display 6 and the displacement detection sensor 4. The displacement detection sensor 4 may also be connected to the digital display 6 by means of wireless communication. In another embodiment, the digital display 6 may be provided separately from the alignment jig, and the digital display 6 may be placed near the alignment jig or at a console of a worker when in use. The displacement detection sensor 4 and the digital display 6 can be connected through a separately arranged pluggable connecting wire, or the displacement detection sensor 4 and the digital display 6 are connected in a wireless communication mode.

As shown in fig. 1 to 4, in this embodiment, a plurality of the displacement detection sensors 4 are included, and the plurality of the displacement detection sensors 4 are at the same height and are uniformly distributed along the circumferential direction of the alignment jig. The mounting portion 42 of each of the displacement detection sensors 4 may be mounted to the outer wall of the connection portion 2 by one sensor bracket 5, respectively, or a plurality of the displacement detection sensors 4 may be mounted to the outer wall of the connection portion 2 by one annular sensor bracket 5. The probe 41 enters at least partially into the cavity at the connection portion 2, and the detection direction of the probe 41 is perpendicular to the axial direction of the alignment jig. In this embodiment, four displacement detection sensors 4 are exemplarily shown, and the displacement detection sensors 4 may be contact type displacement sensors, and when a tool shaft or a tool ram is in contact with the probe 41 of the contact type displacement sensors, the contact type displacement sensors obtain detection data at the probe 41. When the tool shaft or the equipment pressure head passes through the connecting part 2 in use, the tool shaft or the equipment pressure head is contacted with the probe 41 protruding from the inner wall of the cavity, the detection data of the displacement detection sensor 4 can reflect the distance between the tool shaft or the equipment pressure head and the inner wall of the cavity at the installation position, and the smaller the distance between the shaft second part and the inner wall of the cavity at the installation position is, the smaller the detection data is, and the larger the distance between the second part and the inner wall of the cavity at the installation position is. The digital display 6 synchronously displays the detection data of the four displacement detection sensors 4, and a worker can adjust the displacement of the tool shaft or the equipment pressure head by comparing the detection data of the four displacement detection sensors 4, so that the tool shaft or the equipment pressure head is adjusted to be positioned at the very center of the cavity, for example, the axle center of the tool shaft and the axle center of the cavity are in the same straight line.

As shown in fig. 3, for example, the probes 41 of the four displacement detection sensors 4 are defined as a probe 41A, a probe 41B, a probe 41C, and a probe 41D, respectively, the probe 41A and the probe 41C being disposed opposite to each other, and the probe 41B and the probe 41D being disposed opposite to each other. When the tool shaft or equipment pressure head is too biased to the direction of the probe 41A, the equipment pressure head can be controlled to enable the tool shaft or equipment pressure head to be slightly adjusted to the direction of the probe 41C. Likewise, comparing the sensed data at probe 41B with the sensed data at probe 41D, manipulating the device ram when the two-sided data are different causes the tooling shaft or device ram to move to one side. Finally, the detection data of the probe 41A and the detection data of the probe 41C are consistent, and if the detected object is an axis, the detection data of the four displacement detection sensors 4 are required to be the same, so that the tool axis or the equipment pressure head can be ensured to be positioned at the most central position of the cavity. This alignment device with digital display has a significant advantage: the flexible input shafts with different diameters can be aligned in a compatible mode, deviation values in four directions can be accurately quantized, adjustment suggestions are provided, and the flexible input shaft has the characteristics of high flexibility and high accuracy and is convenient to use and master.

Only four displacement detection sensors 4 are described here as an example. In other embodiments, the number of displacement detecting sensors 4 may be increased or decreased, for example, two displacement detecting sensors 4, three displacement detecting sensors 4, six displacement detecting sensors 4, eight displacement detecting sensors 4, etc. may be provided, and one displacement detecting sensor 4 may be provided, where it is necessary for a worker to know in advance the ideal data at the displacement detecting sensor 4, and the adjustment of the alignment is completed when the device indenter adjusts the actual measured data to be equal to the ideal data. When a plurality of displacement detection sensors 4 are provided, they may be uniformly distributed or unevenly distributed and may be installed at a plurality of designated positions. The sensor holders 5 and the displacement detection sensors 4 may be in one-to-one correspondence, or one-to-many correspondence. When other numbers of displacement detection sensors 4 are adopted, the device can adapt to compatible alignment of input shafts with different diameters, accurately quantize deviation values of at least one direction and provide adjustment suggestions, and has the characteristics of high flexibility and high accuracy, and is convenient to use and master.

In the embodiments of fig. 1 to 4, the alignment jig is described as a cylindrical shape. In other embodiments, the alignment jig may have other shapes, such as square columns. The mounting position of the displacement detection sensor may be located at the first jig or the second jig, or displacement detection sensors of different heights may be provided. The above variations are all within the scope of the present application.
