The specific meaning of the above terms in the present utility model can be understood as appropriate by those of ordinary skill in the art.

The technical scheme of the utility model is specifically described below with reference to the accompanying drawings.

The utility model provides a part detection tool, which comprises a driving mechanism 1 and a lifting mechanism, as shown in figure 1. When in use, the lifting mechanism is arranged above the detection station and can lift and move relative to the detection station under the drive of the driving mechanism 1. The piston head to be detected is located at the detection station.

It should be noted that the above-mentioned detecting station refers to a device or structure for placing the piston head or conveying the piston head to a position where a different tool is located, and does not refer to a fixed position.

The lifting mechanism comprises a sealing component 2 and a compacting component 3, and the sealing component 2 is positioned at the lower end of the lifting mechanism; the pressing component 3 is positioned above the sealing component 2 and can provide downward pressing force for the sealing component 2; the part to be detected (in this embodiment, the piston head is taken as an example) is located on the detection station, and the lifting mechanism can be driven by the driving mechanism 1 to move until the sealing assembly 2 is tightly attached to the upper end face of the part to be detected.

Specifically, the driving mechanism 1 includes a driving motor 11, a synchronizing assembly 12 and a ball screw 13, and the lifting mechanism is fixedly connected with the ball screw 13. The driving motor 11 comprises a servo motor and a speed reducer, and the synchronous assembly 12 comprises two synchronous wheels and a synchronous toothed belt connected with the synchronous wheels. The speed reducer and the ball screw 13 are respectively connected with two synchronous wheels. Under the action of the servo motor, the ball screw 13 arranged along the vertical line direction moves up and down and drives the lifting mechanism connected with the ball screw to move synchronously.

It should be noted that the moving range of the lifting mechanism can be adjusted according to actual needs.

The structure of the lifting mechanism is shown in fig. 2 and 3. The specific configuration thereof will be described below with reference to the accompanying drawings.

In this embodiment, the lifting mechanism mainly comprises three parts, namely a sealing assembly 2, a pressing assembly 3 and a pressing assembly 4.

In order to conveniently realize detecting the tightness of the piston head, the tool further comprises a vacuum detection mechanism, wherein the vacuum detection mechanism is in the prior art and comprises an air extractor, a pneumatic detection device and the like, and the vacuum detection mechanism is not described in detail herein.

Specifically, the sealing assembly 2 includes a sealing ring 21 and an air guide passage, as shown in fig. 4 (the air guide passage is not shown).

One end of the air guide channel can be connected with the vacuum detection mechanism through an air guide pipe, and the other end of the air guide channel can be communicated with a part to be detected of the part, as shown in fig. 5.

When vacuum detection is performed, the vacuum detection mechanism is started until the pressure is the working pressure. In this case, the tightness of the component can be detected. Other inspection actions can then be performed on the part by adjusting other component actions while maintaining the pressure environment, at which time the quality of the part can be determined based on the pressure change. If the pressure change range exceeds the equipment processing requirement value, the part fails to pass the detection; otherwise, the part is indicated to be qualified.

The detection mode can realize the detection of a plurality of different indexes (such as spring force of the part, height difference of the part, tightness of the part and the like) on one detection device, and effectively improves the detection efficiency.

In the detection, the shape and size of the seal ring 21 may be adjusted according to the actual structure of the component. For example, the shape of the seal ring 21 may be rectangular or O-shaped.

As an alternative embodiment, the lifting mechanism further comprises a pressing assembly 4; the pressing assembly 4 comprises a pressing cylinder 41 and a push rod 42, and the push rod 42 is arranged through the sealing assembly 2 and the pressing assembly 3 by a linear bearing.

In this embodiment and similar embodiments, the extrusion assembly 4 further includes a connecting member 43 and a bracket 44, wherein the movable end of the extrusion cylinder 41 can be fixedly connected with the bracket 44 via the connecting member 43, and the push rod 42 is located below the bracket 44 and is fixedly connected with the bracket 44. When the pressing cylinder 41 is operated, the bracket 44 and the push rod 42 can be moved up and down in synchronization.

As an alternative embodiment, the lifting mechanism further comprises a displacement detection assembly 5, and the displacement detection assembly 5 is fixedly connected with the extrusion assembly 4 and can move along with the movement of the push rod 42, so that the displacement condition of the push rod 42 can be conveniently obtained.

In this embodiment, the displacement detecting assembly 5 is fixedly connected to the pressing assembly 4 via a bracket 44.

The lower end of the connecting shaft is fixedly connected with the transverse connecting plate 31, and the upper end of the connecting shaft is connected with the fixed plate 7 through a linear bearing. The pushing member 32 is also fixedly provided on the fixing plate 7. When the two pushing members 32 are simultaneously started and pressed down, the transverse connecting plate 31 can move downwards under the action of the pushing members 32 at the moment because the fixing plate 7 is fixed, and the two ends of the transverse connecting plate 31 are balanced in stress. Therefore, the sealing assembly 2 can be uniformly pressed down relative to the part to be detected, so that the pressing force of the part to be detected under the actual use condition can be effectively simulated. At this time, whether the part is qualified or not can be judged according to the detection data at the vacuum detection mechanism.

It should be noted that the transverse connection plates 31 are symmetrically arranged with respect to the push rods 42. In addition, the middle part of the transverse connection plate 31 is provided with a bearing via which the push rod 42 is connected to the transverse connection plate 31.
