[0031] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figures 1-5 As shown, a loading device for a fuel injector housing inspection equipment includes: a support base 40, a carrier plate 60, a drive mechanism 20, a carrier block 50, a storage mechanism 10, and a robot arm 30. The carrier plate 60 is horizontally arranged and rotatably connected to the support base 40. The drive mechanism 20 is drively connected to the carrier plate 60, driving the carrier plate 60 to rotate around its center. The carrier block 50 is fixed at the circumferential edge of the carrier plate 60 and rotates synchronously with the carrier plate 60. The carrier block 50 is provided with a carrier hole 52 for carrying a fuel injector housing 100. The storage mechanism 10 includes several storage positions for storing fuel injector housings 100, which are vertically stored in the storage positions. The robot arm 30 is configured to grasp the fuel injector housings 100 in the storage positions and place them into the carrier holes 52.

[0033] Driven by the drive mechanism 20, the carrier plate 60 rotates intermittently around the support base 40 according to the detection rhythm, so as to ensure that when the robot arm 30 is stopped, it can grab the fuel injector housing 100 stored in the storage mechanism 10 and place the fuel injector housing 100 in the carrier hole 52. When the carrier plate 60 rotates under the drive mechanism 20, it can transport the fuel injector housing 100 placed in the carrier hole 52 to the detection position.

[0034] It should be noted that the drive mechanism 20 is a drive motor, which is selected from existing finished motors based on the corresponding speed and torque, and will not be elaborated here.

[0035] In this embodiment, the fuel injector housing 100 is a rotating body, and its overall structure can be divided into an upper housing 101 and a lower housing 103. The outer diameter of the upper housing 101 is significantly larger than that of the lower housing 103. Furthermore, a housing platform stage 102 exists between the upper housing 101 and the lower housing 103. The outer diameters of the upper housing 101 and the lower housing 103 change significantly at the housing platform stage 102.

[0036] The support block 50 includes a block body 51, and a support hole 52 extends vertically through the block body 51. The support hole 52 includes a first support portion 521 and a second support portion 522 that are interconnected, and the first support portion 521 is located above the second support portion 522.

[0037] The inner diameter of the first supporting part 521 is adapted to the upper housing 101, so that the first supporting part 521 can fully accommodate the upper housing 101 and limit the outer diameter of the fuel injector housing 100, so that the fuel injector housing 100 remains vertical and will not tip over.

[0038] Similarly, the inner diameter of the second supporting portion 522 is adapted to the lower housing 103, so that the second supporting portion 522 can fully accommodate the lower housing 103 and limit the outer diameter of the fuel injector housing 100, so that the fuel injector housing 100 remains vertical and will not tip over.

[0039] Furthermore, since the outer diameter of the upper housing 101 is larger than the outer diameter of the lower housing 103, the diameter of the first bearing portion 521 is also larger than the diameter of the second bearing portion 522.

[0040] The block 51 is also provided with fixing holes 53 for fixing the support block 50 and the support plate 60. The support block 50 is fixedly connected to the support plate 60 by bolts passing through the fixing holes 53.

[0041] Preferably, the support block 50 is made of plastic material to prevent damage to the fuel injector housing 100 when it comes into contact with it.

[0042] During loading, the robotic arm 30 grabs the fuel injector housing 100 stored in the storage mechanism 10 and places the fuel injector housing 100 above the bearing hole 52, aligning the center of the fuel injector housing 100 with the center of the bearing hole 52. Then, the robotic arm 30 releases the fuel injector housing 100, allowing it to fall naturally into the bearing hole 52.

[0043] In another embodiment of this utility model, the bearing hole 52 further includes a third bearing portion 523 communicating with the second bearing portion 522. The third bearing portion 523 is located below the second bearing portion 522, and the diameter of the third bearing portion 523 is smaller than the diameter of the second bearing portion 522. The third bearing portion 523 can increase the adaptability of the bearing block 50, enabling the bearing block 50 to support fuel injector housings 100 of different specifications.

[0044] As another embodiment of this utility model, such as Figure 6 As shown, a fuel injector housing detection equipment loading device further includes an ejection and unloading mechanism 70 for extending into the bearing hole 52 to eject the fuel injector housing 100 out of the bearing hole 52.

[0045] The ejector unloading mechanism 70 includes a lifting component 71 and an ejector rod 72 fixedly connected to the moving end of the lifting component 71; the upper end of the ejector rod 72 is provided with an ejection receiving cavity for accommodating the lower end of the fuel injector housing 100. Relying on the lifting action of the ejector unloading mechanism 70, the fuel injector housing 100 can be ejected from the support block 50, effectively reducing the number of movements of the robot arm 30 and improving the unloading efficiency.

[0046] When the fuel injector housing 100 is pushed out of the bearing hole 52 by the ejector rod 72, the bearing effect of the receiving cavity prevents it from contacting the inner surface of the fuel injector housing 100, thus preventing damage to the inner surface of the fuel injector housing 100. At the same time, the limiting effect of the receiving cavity prevents the fuel injector housing 100 from moving unrestricted in the horizontal direction during the ejection process.

[0047] Preferably, the lifting component 71 is one of a lifting hydraulic cylinder, a lifting pneumatic cylinder, or an electric push rod.

[0048] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0049] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
