Description

Technical Field

[0001] This utility model relates to the field of encoder zero-point recovery technology, and in particular to a mechanical device for quickly recovering lost encoder position data. Background Technology

[0002] To meet the production needs of various vehicle models at OEMs and save on investment costs, most OEM welding workshops utilize flexible production lines. Typically, flexible lines use large turntables / hubs to accommodate multiple vehicle models. To ensure the accuracy of the turntable / hub's position, inverters and encoders are usually used to control its rotation. Sudden power outages or other issues can cause malfunctions in the inverters or encoders, resulting in the loss of the turntable / hub's current position and zero-point data (electrical position). When encoder position data is lost, two methods are generally used to recover it: one is to manually rotate the turntable / hub to roughly confirm the position and then re-teach other equipment based on the new position; the other is to restore the turntable / hub to its original position as much as possible based on the status of other equipment / facilities, after which other equipment makes minor adjustments based on the position status. Due to the lack of reference points or large reference point errors, a significant amount of time is required to recalibrate the position and restore normal production line operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 2 A mechanical device for rapidly recovering lost encoder position data, comprising:

[0020] A reference base 10 is mounted on a turntable fixed base, and the reference base 10 is provided with a V-shaped groove 101;

[0021] Indicating instrument 2;

[0022] Connector 3 is installed on the rotating part of the turntable;

[0023] A fixing device is provided on the connector 3 to fix the indicating instrument 2 to the connector 3. In this utility model, the reference base 10 is set on the turntable fixed base, and the lowest point of the V-shaped groove 101 is set as the zero point position for zero point calibration. When the encoder is damaged or the power is cut off, resulting in the loss of zero point storage data, the indicating instrument 2 is rotated by rotating the turntable rotating part. The indicating instrument 2 is a dial indicator. When the dial indicator probe reaches the deepest point of the groove 101 during the movement of the dial indicator, the zero point position of the encoder can be obtained by observing when the pointer points to the lowest digital point.

[0024] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0025] In this embodiment, the connector 3 is provided with a first countersunk hole 301 and a placement groove 302; the fixing device includes a fixing box 4 and at least two locking members 5. The fixing box 4 has openings on both sides and a second countersunk hole 401 at its bottom. The locking members 5 pass through the placement groove 302 and are detachably connected to the fixing box 4. During installation, the probe of the indicator 2 passes through the second countersunk hole 401, and the bushing at the top of the indicator 2 engages with the first countersunk hole 301. The top of the probe can move within the first countersunk hole 301. After the top of the fixing box 4 engages with the placement groove 302, the locking members 5 connect the connector 3 and the fixing box 4, thereby fixing the fixing box 4 onto the connector 3. The rear side of the indicator 2 contacts the rear side of the fixing box 4 to prevent the indicator 2 from rotating. Since the indicator 2 is set inside the fixing box 4, it plays a protective role for the indicator 2.

[0026] In this embodiment, both the connector 3 and the fixing box 4 are provided with threaded holes. The locking member 5 is a bolt. The bolt passes through the threaded hole on the connector 3 and connects with the threaded hole on the fixing box 4, thereby fixing the fixing box 4 on the connector 3.

[0027] In this embodiment, the fixing device further includes a protective sleeve 6. The top end of the protective sleeve 6 is screwed to the wall of the second countersunk hole 401. After the protective sleeve 6 is screwed to the wall of the second countersunk hole 401, the probe of the indicating instrument 2 is placed inside it, which serves to protect the probe.

[0028] In this embodiment, the reference base 10 is detachably connected to the turntable fixing base, facilitating the installation and removal of the reference base 10. Specifically, the reference base 10 is provided with multiple through holes.

[0029] In this embodiment, the connector 3 is detachably connected to the rotary table, facilitating the installation and removal of the connector 3. When another rotary table needs to find its zero point, the connector 3 is removed, and the zero point position of the encoder is obtained when the probe of the indicating instrument 2 is aligned with the lowest point of the groove 101 on the reference base 10 on the fixed base of the rotary table. Specifically, the connector 3 is provided with multiple through holes.
