Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 to 6, the following technical solutions are adopted in the present embodiment: a detection device for special parts comprises a base 1, a safety light curtain 2, an electric servo cylinder mechanism 3, a multifunctional fixed support 4, a displacement sensor 5, a force sensor 6, a part to be detected 7, a proximity switch 8, a proximity switch support 9, a pressing block 10, a positioning seat assembly 11, a measurement window 12, a feeding guide rail 14 and a pressing block cylinder 15, wherein the base 1 is fixed on a workbench, the two feeding guide rails 14 are parallelly erected on the base 1, the positioning seat assembly 11 is arranged on the feeding guide rail 14, the part to be detected 7 is placed on the positioning seat assembly 11, the proximity switch support 9 is arranged on the left side of the positioning seat assembly 11, the proximity switch 8 is fixed inside the proximity switch support 9, the two pressing block cylinders 15 are symmetrically arranged on the two sides of the feeding guide rail 14, the pressing block 10 is transversely arranged on the pressing block cylinder 15, the multifunctional fixed support 4 is arranged in the middle of the base 1, the electric servo cylinder mechanism 3 is arranged at the upper end of, force transducer 6 and displacement sensor 5 set up respectively on multi-functional fixed bolster 4, and force transducer 6 below is provided with measurement window 12, and base 1 one side still is provided with safe light curtain 2, ensures operation process safety.

It is noted that the measuring window 12 and the part 7 to be measured are provided with measuring contacts 13.

The working principle of the specific embodiment is as follows: in a state to be detected, the positioning seat assembly 11 is positioned at the far end of each sensor so as to facilitate the picking and placing of a part to be detected; the part 7 to be detected is placed in the circular sunken structure on the positioning seat assembly, after a detection program is started, the positioning seat assembly 11 moves to a specified position along the direction of the feeding guide rail, and at the moment, a measurement contact point area on the part enters a measurement window; the proximity switch of the part to be detected sends a signal after detecting the part, and the pressing block cylinder 15 drives the pressing block to move downwards to fix the part; after the electric servo cylinder mechanism starts to move upwards, after two measuring contact points 13 in a window to be measured and on a part are contacted, the corresponding force is recorded by the force sensor, meanwhile, the corresponding displacement is recorded by the displacement sensor and is transmitted to corresponding hardware in real time, and a force-displacement curve is automatically generated through a pre-programmed program; after the measurement is finished, the electric servo cylinder resets, the pressing block cylinder resets, and the part moves backwards along with the positioning seat assembly, so that the part can be taken out. The safety light curtain 2 stops running when detecting the blocking signal in the whole process, and the process safety is ensured.

Example 1: the measured part of the embodiment is an exhaust valve with an elastic gasket, the structure of which is shown in fig. 4 and 5, the measured part 7 comprises a first gasket 7-1, a second gasket 7-2, a rocker arm 7-3 and a valve cover 7-4, the inner end of the rocker arm 7-3 is sleeved with the valve cover 7-4, and the valve cover 7-4 is connected with the first gasket 7-1 through the second gasket 7-2. The second gasket 7-2 is an elastic gasket.

A wastegate valve with a resilient gasket of this embodiment requires a "force-displacement curve" corresponding to the resilient gasket (as shown in fig. 6) to be checked to verify compliance with design requirements.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
