Description

Technical Field

[0001] The utility model belongs to the technical field of detection, and in particular relates to an inner and outer diameter detection mechanism for a thrust flat gasket. Background Art

[0002] Thrust flat washers are used in thrust bearings. They serve as the thrust bearing track to position and bear loads. To ensure the performance of the bearing, the inner and outer diameters of the washers need to be tested.

[0003] Conventional gasket inspections are carried out manually using plug gauges to inspect the inner diameter and outer diameter respectively. Due to the large number of gaskets, the workload of inspectors is very large and the cost is high. In addition, manual inspections often result in human errors, which reduces the inspection accuracy. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to solve the problem that the gasket detection in the prior art all adopts manual inspection of the inner diameter and the outer diameter respectively through a plug gauge, due to the large number of gaskets, the workload of the inspectors is large and the cost is high, and manual inspection often has human errors, resulting in reduced inspection accuracy. A thrust flat gasket inner and outer diameter inspection mechanism is now provided.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a thrust flat gasket inner and outer diameter inspection mechanism, comprising a base, a sliding rod is longitudinally arranged on the base, a plurality of gaskets are sequentially sleeved on the outside of the sliding rod from top to bottom and can slide down by gravity, an inner diameter through gauge for gaskets with qualified inner diameters to pass through is provided at the bottom of the sliding rod, the two are detachably connected, and an outer diameter leakage gauge for gaskets with qualified outer diameters to pass through is fixed on the base, the outer diameter leakage gauge is located below the inner diameter through gauge and the two are coaxially arranged.

[0006] During inspection, first remove the sliding rod from the base and put multiple gaskets to be tested on the outside of the sliding rod in turn through the inner diameter gauge at the bottom of the sliding rod. The gaskets that can pass through the inner diameter gauge smoothly are qualified inner diameter products, and those that cannot be smoothly inserted are defective products. Then, while supporting the gasket, place the sliding rod with the gasket vertically on the base. In the process of the gasket sliding down by its gravity, since the inner diameter of the gasket has been inspected and qualified during loading, the gasket can smoothly pass through the sliding rod and the inner diameter gauge and continue to slide down to the outer diameter leakage gauge. When the outer diameter of the gasket is larger than the inner diameter of the outer diameter leakage gauge, it cannot pass through the outer diameter leakage gauge and will be stuck, and it needs to be taken out; when the outer diameter of the gasket is less than or equal to the inner diameter of the outer diameter leakage gauge, it can slide down through the outer diameter leakage gauge and is a qualified product.

[0007] The above technical scheme first uses an inner diameter through gauge to detect the inner diameter of the gasket during the gasket sleeve process, and then relies on the gasket's own gravity to detect the outer diameter of the gasket during its falling process using an outer diameter leakage gauge. The inner diameter and outer diameter detection can be achieved at one time, and a sliding rod is used to allow multiple gaskets to be sleeved, thereby achieving synchronous detection of multiple gaskets, thereby improving detection efficiency.

[0008] Furthermore, the base includes a bottom plate, a top plate for hanging the sliding rod, and a longitudinal plate connecting the bottom plate and the top plate, the top plate is provided with a U-shaped groove, the notch of the U-shaped groove passes through a side wall of one side of the top plate, the sliding rod includes a rod body and a cap body located on the top of the rod body, the cross-sectional area of ​​the cap body is larger than the cross-sectional area of ​​the rod body, the hanging setting of the sliding rod can be realized when the rod body passes through the U-shaped groove and the cap body abuts against the top plate, when the gasket mounted on the sliding rod is unqualified or the inspection is completed, the sliding rod can be moved out of the notch of the U-shaped groove to remove the unqualified gasket or install the next batch of gaskets to be inspected.

[0009] Furthermore, a mounting seat is provided on the bottom plate, and a slot for inserting the outer diameter leakage gauge is provided on the top of the mounting seat, and the outer diameter leakage gauge can be positioned after being inserted into the slot.

[0010] Furthermore, a transition groove is provided at the bottom of the mounting seat for gaskets with qualified outer diameter to fall into. The transition groove is an inverted U-shaped structure and a dividing cylinder is provided on the base for pushing the qualified gasket out of the transition groove; the gasket that passes the outer diameter leakage gauge falls into the transition groove, and the output end of the dividing cylinder extends to push the qualified gasket out of the transition groove.

[0011] Furthermore, a first photoelectric sensor is provided in the transition groove, and a second photoelectric sensor is provided at one end of the base away from the dividing cylinder. When a qualified gasket falls into the transition groove, the first photoelectric sensor senses the gasket, and the dividing cylinder pushes the gasket out of the transition groove. If the first photoelectric sensor cannot sense a signal for a long time, it means that a defective outer diameter part is stuck in the outer diameter gauge, or there is no material to be inspected; when the gasket reaches the second photoelectric sensor, the second photoelectric sensor sends a signal, and the dividing cylinder will automatically retreat. If the second photoelectric sensor has no signal for a long time when the dividing cylinder is pushed out, it means that material is stuck or the dividing cylinder is damaged when the dividing cylinder is pushed out.

[0012] Furthermore, the inner ring of the outer diameter leakage gauge is provided with a chamfer to guide the contact between the outer diameter leakage gauge and the gasket, and the outer ring of the inner diameter pass gauge is also provided with a chamfer to guide the contact between the inner diameter pass gauge and the gasket.

[0013] Furthermore, an inclined surface is provided at one end of the base plate away from the material distribution cylinder for the gasket to fall. When the cylinder pushes the qualified gasket to this position, it can fall along the inclined surface. The design of this inclined surface allows the distribution cylinder to have a push-out stroke that does not need to be too large, and also takes into account the minimum placement distance of the sensor, saving tooling size and the area occupied by the mechanism placement.

[0014] The beneficial effects of the utility model are as follows: the utility model firstly uses an inner diameter through gauge to detect the inner diameter of the gasket during the process of gasket sleeve installation, and then relies on the gasket's own gravity to detect the outer diameter of the gasket during its falling process using an outer diameter leakage gauge, which can realize the detection of the inner diameter and the outer diameter at one time, and uses a sliding rod to allow multiple gaskets to be sleeved, thereby realizing synchronous detection of multiple gaskets and improving detection efficiency.

[0032] The slide bar 2 includes a rod body 201 and a cap body 202 located on the top of the rod body 201. The cross-sectional area of ​​the cap body 202 is larger than that of the rod body 201. When the rod body 201 passes through the U-shaped groove 1021 and the cap body 202 abuts against the top plate 102, the suspension setting of the slide bar 2 can be realized. When the gasket 7 mounted on the slide bar 2 is unqualified or the inspection is completed, the slide bar 2 is moved out of the notch of the U-shaped groove 1021 to remove the unqualified gasket 7 or install the next batch of gaskets 7 to be inspected.

At this time, the dividing cylinder 5 pushes the gasket 7 out of the transition groove 1042. When the gasket 7 reaches the second photoelectric sensor 8, the second photoelectric sensor 8 sends a signal. At this time, the dividing cylinder 5 will automatically retreat, and the gasket 7 falls along the inclined surface 105.
