Illustratively, the part hole site machining leakage detection apparatus 100 includes a mounting bracket 10, a plurality of detection execution assemblies 20, and a detection sensor 30.

The detection execution assemblies 20 are movably arranged on the mounting bracket 10, each detection execution assembly 20 is used for being respectively arranged in one-to-one alignment with the hole site on the part, and each detection execution assembly 20 comprises a detection end and a trigger end which are oppositely arranged; the detection sensor 30 is disposed on the mounting bracket 10 and is disposed near the trigger end, and the trigger end and the detection sensor 30 trigger when the detection executing assembly 20 is blocked by the part from retreating.

In summary, implementing the technical scheme of the embodiment has the following beneficial effects: when the part hole site leakage machining detection equipment 100 is used, a detection device is installed and fixed on a functional component (such as a peripheral liquid receiving disc) in a detection area or around the detection area through a mounting bracket 10, at the moment, a detection execution component 20 keeps an initial state, a trigger end keeps a safe distance from a detection sensor 30, and the detection sensor 30 is not triggered; during detection, a part (such as a cylinder cover conduit valve seat) subjected to primary processing is moved into a detection area through a truss manipulator, the hole positions on the part and the detection execution assemblies 20 are arranged in a one-to-one alignment mode, under normal conditions, when the hole positions on the part are processed normally, the detection ends of the detection execution assemblies 20 can smoothly extend into the hole positions, the detection execution assemblies 20 cannot retreat, but when a certain hole position is subjected to missed processing conditions, the detection execution assemblies 20 corresponding to the missed processing hole positions retreat due to blocking of the part, the triggering end shields the detection sensor 30, the detection sensor 30 feeds back signals to the controller to perform missed processing alarm, and workers are reminded of timely intervention, so that the part with the missed processing problem can be prevented from flowing into a finishing process, the problems of a tool box collision machine and tool breakage are avoided, and unnecessary economic losses are avoided.

Typically, a row(s) of holes are machined in the cylinder head conduit valve seat, with the holes being arranged in a straight line. The hole sites may be through holes or blind holes. Thus, to accommodate the inspection requirements of the plurality of hole sites so configured, in some alternative embodiments, the plurality of inspection execution assemblies 20 are arranged side-by-side in at least one row on the mounting bracket 10; and in the initial state, all detection ends of the detection execution assemblies 20 are flush, and all trigger ends of the detection execution assemblies 20 are flush.

After the device is arranged, the truss machine writer only needs to adjust the cylinder cover conduit valve seat and the detection device (for short, the detection device is used for detecting the leakage of the part hole site) to the horizontal position, so that the detection execution assembly 20 is horizontally aligned with the hole site one by one, then the cylinder cover conduit valve seat is moved to be close to the detection device, and the detection end can be inserted into the corresponding hole site, so that the detection operation is completed, the detection mode is simple and efficient, and the practicability is strong. Meanwhile, the structural arrangement requirements on a plurality of detection execution assemblies 20 of the detection device are low, the structural arrangement of the plurality of detection execution assemblies 20 is regular and simple, and the design and manufacturing difficulties and cost of the detection device are reduced.

It is easy to understand that the detection end and the trigger end of each detection execution assembly 20 are all kept flush in the initial state, which helps to ensure accuracy of the detection result, and avoid false triggering of the detection sensor 30.

With continued reference to fig. 1 and 2, in some alternative embodiments, the mounting bracket 10 includes a carrier plate 11, and the carrier plate 11 is rectangular. The support plate 11 is provided with a mounting through hole, the detection execution assembly 20 comprises a detection seat 21 and a detection rod 22, the detection seat 21 is arranged on the support plate 11, the detection seat 21 is provided with sliding holes penetrating through two opposite ends of the detection seat, the sliding holes are aligned with the mounting through hole, and the detection rod 22 penetrates through the sliding holes and can slide relative to the detection seat 21 under the stress condition.

The detection seat 21 is fixedly connected with the carrier plate 11, so that the detection execution assembly 20 and the mounting bracket 10 are reliably assembled, the detection rod 22 is arranged in the sliding hole in a penetrating mode and is slidably mounted with the detection seat 21, when the hole position leakage machining occurs on the part, and the detection rod 22 is applied with blocking force, the detection rod 22 can slide backwards in the sliding hole and the mounting through hole in the direction away from the part, one end, away from the part, of the detection rod 22 shields the detection sensor 30, and then the detection sensor 30 is triggered.

With continued reference to fig. 3 and 4, optionally, the inspection seat 21 includes a seat cylinder 211 and a flange 212, where the flange 212 is mounted on an outer cylinder wall of the seat cylinder 211, and the flange 212 is connected to the carrier 11. The seat cylinder 211 plays a role of a linear bearing, plays a role of guiding and limiting the linear sliding of the detection rod 22, and ensures that the detection rod 22 moves stably and reliably. The flange 212 and the carrier plate 11 can be assembled and fixed by any one of screw connection, buckle connection, magnetic attraction connection, adhesion and the like, so that the requirement of assembling the detection execution assembly 20 and the mounting bracket 10 is met.

In addition, on the basis of any of the above embodiments, the detection rod 22 includes the small-diameter rod section 221 and the large-diameter rod section 222, and the small-diameter rod section 221 and the large-diameter rod section 222 are coaxially connected and cooperate to form a positioning step; the end of the small-diameter rod section 221 away from the large-diameter rod section 222 is set as a detection end, and the end of the large-diameter rod section 222 away from the small-diameter rod section 221 is set as a trigger end.

The small-diameter rod section 221 is relatively smaller in diameter and is easier to be matched and spliced with hole sites with different hole diameters, so that the application range of the detection execution assembly 20 is enlarged, the formed positioning step is abutted against the side wall of the hole site of the part forming area, and therefore the feeding of the part towards the detection device can be positioned, for example, a pressure sensor is arranged on the positioning step, and after the pressure sensor is abutted against the side wall of the part, a signal is fed back to the controller, so that the controller controls the truss manipulator to stop driving the part to feed towards the detection device, the situation that the part excessively extrudes the detection execution assembly 20 to cause the detection execution assembly 20 to retreat to trigger the detection sensor 30 by mistake is avoided.

With continued reference to fig. 3 and 4, further, the detection executing assembly 20 further includes an elastic member 23, a limit baffle 24 is further disposed between the small-diameter rod section 221 and the large-diameter rod section 222, the elastic member 23 is telescopically disposed outside the large-diameter rod section 222, one end of the elastic member 23 abuts against the limit baffle 24, and the other end of the elastic member 23 abuts against one of the end surfaces of the detection seat 21.

When the detecting rod 22 is blocked by the part and retreats, the limiting baffle 24 presses the elastic piece 23 to enable the elastic piece 23 to elastically shrink; when the detection operation is finished, after the transfer part of the truss manipulator leaves, the elastic piece 23 releases the elastic force to push the detection rod 22 to automatically reset, so that the detection device is used for a second time, and the automation level of the detection device is improved.

Optionally, the elastic member 23 adopts a spring, and the spring is sleeved outside the large-diameter rod section 222, so that the installation is more stable, and the large-diameter rod section 222 plays a role in limiting and guiding the expansion and deformation of the spring.

In addition, in addition to any of the above embodiments, the mounting bracket 10 further includes a first mounting plate 12 and a second mounting plate 13, the first mounting plate 12 is disposed at one end of the carrier plate 11 in the longitudinal direction, and the second mounting plate 13 is disposed at the other end of the carrier plate 11 in the longitudinal direction. It can be appreciated that the first mounting plate 12, the carrier plate 11 and the second mounting plate 13 cooperate to form a U-shaped plate structure, and according to practical needs, the first mounting plate 12 and the second mounting plate 13 may be integrally formed with the carrier plate 11, for example, formed by bending a plate, and may, of course, also be detachably assembled.

Wherein, first mounting panel 12, support plate 11 and second mounting panel 13 enclose into and have the holding chamber, and during initial state, detection seat 21 and trigger end all are located the inside in holding chamber. In addition, when the detecting rod 22 is blocked by the part so that the triggering end extends out of the detecting seat 21, the accommodating cavity can also provide enough movement travel required by the triggering end, so that the other parts around can prevent the triggering end from extending normally and not effectively shielding and triggering the detecting sensor 30.

Further, the first mounting plate 12 is provided with a first bar-shaped notch 121, and the second mounting plate 13 is provided with a second bar-shaped notch. The first strip-shaped notch 121 and the second strip-shaped notch can penetrate into the bolts, so that the mounting bracket 10 can be fixed to the functional components in the detection area or around the detection area through bolt screwing, the mounting mode is simple, the connection is stable and reliable, and the mounting bracket is convenient to assemble and disassemble.

Still further, the first bar-shaped notch 121 is aligned with the second bar-shaped notch, the detecting sensor 30 includes a transmitting sensor 31 and a receiving sensor 32, one of the transmitting sensor 31 and the receiving sensor 32 is mounted on the first mounting plate 12, the other of the transmitting sensor 31 and the receiving sensor 32 is mounted on the second mounting plate 13, and the detecting light emitted by the transmitting sensor 31 reaches the receiving sensor 32 through the first bar-shaped notch 121, the accommodating cavity and the second bar-shaped notch.

That is, the detection light is ensured to pass through the inside of the accommodating cavity, on one hand, the detection light can be blocked by the trigger end moving backwards for a short stroke, and the detection sensor 30 is reliably triggered; on the other hand, the trigger end can be prevented from extending out of the accommodating cavity and being easily interfered by surrounding parts, so that the detection light can not be effectively shielded.
