Description

Technical Field

[0001] The utility model relates to the technical field of chain detection, in particular to automatic chain transmission detection equipment. Background Art

[0002] Chains can be divided into roller chains, toothed chains and other types according to their structure, among which roller chains are the most widely used. Roller chains consist of inner link plates, outer link plates, pins, sleeves and rollers. The inner link plates and sleeves, and the outer link plates and pins are connected by interference fit, respectively, and are called inner and outer chain links; the rollers and sleeves, and the sleeves and pins are clearance fits. When the inner and outer link plates are relatively flexed, the sleeves can rotate freely around the pins. The rollers are movably mounted on the sleeves. When working, the rollers roll along the sprocket tooth profiles to reduce the wear of the gear teeth.

[0003] At present, in most chain production processes, chain inspection is carried out manually, that is, relying on the experience of inspectors, judging whether the chain is qualified by appearance observation and feel, which is inefficient. By using mechanical inspection, it is generally necessary to put the chain on the inspection machine, clamp the chain by the inspection unit above, and then drive the chain. The transmission of the chain is observed by the inspection unit to judge whether the chain is qualified. However, the lengths of the chains are different, which is not convenient for inspecting chains of different specifications. In order to further improve work efficiency and facilitate the inspection of chains of different lengths, the utility model proposes a chain automatic transmission inspection device.

[0031] The adjustment mechanism 7 includes a limit unit and a transmission unit;

[0032] The limiting unit is used to limit the rotation of the second tensioning wheel 5 and the tensioning rod 6;

[0033] The transmission unit is used to control the synchronous rotation of the second tensioning wheel 5 and the tensioning rod 6;

[0034] The transmission unit includes a push block 701, a rack 702, a first gear 703, and a second gear 704;

[0035] The push block 701 is vertically slidably mounted on one side outer wall of the workbench 1, and the push block 701 is used to drive the rack 702 to move synchronously;

[0036] The rack 702 is fixed to one end of the push block 701, and the rack 702 is used to push the first gear 703 to rotate;

[0037] The first gear 703 is fixed to the outer wall of the first tensioning wheel 4 and is located inside the workbench 1. The first gear 703 is used to drive the second gear 704 to rotate;

[0038] The second gear 704 is fixed to the outer wall of the second tensioning wheel 5, and the second gear 704 is used to rotate in the opposite direction under the drive of the first gear 703;

[0039] The limiting unit includes a rotating rod 705, a threaded rod 706, a stop block 707, and a rubber pad 708;

[0040] The rotating rod 705 is fixed to one end of the threaded rod 706 to drive the threaded rod 706 to rotate;

[0041] The threaded rod 706 is rotatably mounted inside the push block 701 and extends to the outside of the push block 701. The threaded rod 706 is used to drive the stop block 707 to rotate;

[0042] The stop block 707 is fixed to one end of the threaded rod 706, and the stop block 707 is used to limit the up and down movement of the push block 701;

[0043] The rubber pad 708 is fixed on the workbench 1 and contacts the outer wall of the stop block 707 . The rubber pad 708 is used to provide friction for the stop block 707 .

[0044] In this embodiment: when using this device, the inner side of the chain to be tested is engaged with the outer wall of the coupling wheel 3. At this time, the positioning rod 2 and the tensioning rod 6 are at the minimum distance. By rotating the rotating rod 705, the rotating rod 705 rotates and drives the threaded rod 706 to rotate. The rotating threaded rod 706 will synchronously drive the block 707 to rotate, so that the block 707 changes from horizontal to vertical, so that the two ends of the block 707 are no longer tightly attached to the outer wall of the rubber pad 708, and the vertical movement limit of the push block 701 is released. At this time, the push block 701 can be given an upward thrust, and the upward moving push block 701 will synchronously drive the rack 702 to move, and the upward moving rack 702 will give a thrust to the first gear 703 engaged with its outer wall, and the first gear 703 will rotate under this thrust and synchronously drive the second gear 704 to rotate. At this time, the rotation directions of the first gear 703 and the second gear 704 are opposite, so that the rotation directions of the first tensioning wheel 4 and the second tensioning wheel 5 are also opposite, and the tensioning rod 6 connected to the first tensioning wheel 4 and the second tensioning wheel 5 will also rotate with the first tensioning wheel 4 and the second tensioning wheel 5 rotates and the axis of the first tensioning wheel 4 and the second tensioning wheel 5 makes circumferential motion, so that the two tensioning rods 6 move away from each other until the chain sleeved on the sleeve wheel 3 and the tensioning rod 6 is tight. At this time, the rotating rod 705 can be rotated again to make the stop block 707 close to the outer wall of the rubber pad 708, thereby completing the vertical movement limit of the push block 701. The taut chain can use a driving motor connected to the positioning rod 2 to drive a positioning rod 2 to rotate. The rotating positioning rod 2 will drive the chain sleeved on the sleeve wheel 3 and the tensioning rod 6 to transmit the chain. The chain is scanned by the detection head arranged on the workbench 1, and the scanned electrical signal is transmitted to the built-in processor with the position information, so as to complete the detection of the chain in the transmission state, thereby achieving the purpose of quickly limiting the chains of different specifications and lengths, and further improving the work efficiency.

[0045] Please refer to Figure 1-Figure 3 The outer walls of the first gear 703 and the second gear 704 are meshed with each other, the positions of the two tensioning rods 6 are symmetrical to each other, the installation positions of the tensioning rod 6 and the second tensioning wheel 5 and the first tensioning wheel 4 are far away from the axis of the first tensioning wheel 4 and the second tensioning wheel 5, and the inner wall of the workbench 1 is formed with a slide groove for the vertical movement of the push block 701 and the rack 702. One end of a positioning rod 2 is connected to the driving motor through a rotating shaft and a coupling, which is used to drive the positioning rod 2 to rotate and thereby drive the chain transmission.

[0046] In this embodiment: through this structure, the first tensioning wheel 4 and the second tensioning wheel 5 can be rotated to make the tensioning rod 6 eccentrically connected to the second tensioning wheel 5 and the first tensioning wheel 4 move away from each other, so that the chain connected to the sleeve wheel 3 and the tensioning rod 6 is tightened, thereby achieving the purpose of quickly positioning chains of different lengths.

[0047] Please refer to Figure 1-Figure 3The inner wall of the workbench 1 is formed with a movable groove for the vertical movement of the push block 707. There are two rubber pads 708. The two rubber pads 708 are fixed in the inner movable groove of the workbench 1 and are symmetrically distributed on both sides of the push block 707. The outer wall of the rubber pad 708 is an oval structure as a whole. The inner cavity of the push block 701 is formed with a threaded groove matching the outer wall of the threaded rod 706.

[0048] In this embodiment, this structure ensures that the elliptical abutment block 707 does not contact the outer wall of the rubber pad 708 when in the vertical state, but abuts against the outer wall of the rubber pad 708 when in the horizontal state, thereby limiting the vertical movement of the push block 701.
