[0002] For the traditional assembly and connection process of valve body parts, threaded connection, welding and other methods are often used to connect the parts together. For threaded connection, the processing accuracy of the hole is relatively high, and the connection strength will be weakened; for welding, due to the high temperature, the connector will be thermally deformed, which will cause the size and shape of the parts to change, resulting in low assembly accuracy and even air and liquid leakage. Because some mechanical parts are used in extreme environments, it is required that they can still maintain a good fixed connection effect under the above extreme environments.

Specifically, it provides a solenoid valve body base for an electronically controlled shock absorber, the solenoid valve body base includes a base part, an intermediate connecting part and a base top part, and the base part, the intermediate connecting part and the base top part have relative interference dimensions, so that the base part, the intermediate connecting part and the base top part will produce an interference effect when they are matched without any fasteners; the base top part is used for detachable connection with the upper tooling, and the base part is used for detachable connection with the lower tooling; the upper tooling and the lower tooling are used to realize the press-fitting of various components of the solenoid valve body base; a two-dimensional code is laser-printed on the surface of the base part, the intermediate connecting part and the base top part, and the two-dimensional code is used to track the changes in the pressing pressure of the interference fit during processing.
[0004] Furthermore, the base part and the top part are connected via the intermediate connecting member.
[0005] Furthermore, the upper tooling is composed of an upper tooling seat body and a guide cone, a receiving cavity is provided at the bottom of the upper tooling seat body, a guide cone is provided in the receiving cavity, and the guide cone realizes the guiding installation of the base top part; the lower tooling is composed of a lower tooling seat body and a positioning frame, the positioning frame is accommodated in the lower tooling seat body, a positioning groove is provided at the top of the positioning frame, and the base part is detachably arranged in the positioning groove, thereby realizing the positioning of the base part.

[0007] .Furthermore, the QR code stores information about the corresponding parts, including the pressing pressure threshold range, manufacturer information, and production date.
[0008] Furthermore, the upper tooling and the lower tooling are used to realize the interference fit of the parts of the solenoid valve body base. During the interference fit assembly process, an external pressure monitoring device is used to scan the QR code to read the pressing pressure threshold range information. At the same time, the pressure monitoring device monitors the interference fit pressing pressure during the assembly process in real time.
[0009] Furthermore, the interference fit pressing pressure monitored in real time is compared with the pressing pressure threshold range information stored in the QR code.

[0010] Compared with the prior art, the electromagnetic valve body base for an electric shock absorber of the utility model has the following beneficial effects: the various parts of the electromagnetic valve body base are set to a structure with a relative interference size, and then the above parts are press-fitted with interference fit by using a press-fitting device including an upper tooling and a lower tooling with a specific structure, so that a tight connection is formed between the parts.

[0019] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.
[0020] like Figure 1-7 The utility model provides a solenoid valve body base for an electric-controlled shock absorber, and the solenoid valve body base includes a base part 1, an intermediate connecting part 2 and a base top part 3. The base part 1, the intermediate connecting part 2 and the base top part 3 have relative interference dimensions, so that the base part 1, the intermediate connecting part 2 and the base top part 3 will produce an interference effect when they are matched without any fasteners; the base top part 3 is used to be detachably connected to an upper tooling 4, and the base part 1 is used to be detachably connected to a lower tooling 5; the upper tooling 4 and the lower tooling 5 are used to realize the press-fitting of various components of the solenoid valve body base, thereby realizing the interference fit installation between the base part 1, the intermediate connecting part 2 and the base top part 3; the base part 1 and the base top part 3 are connected and arranged through the intermediate connecting part 2.
[0021] Specifically, the upper tooling 4 is composed of an upper tooling seat body and a guide cone, the bottom of the upper tooling seat body is provided with a receiving cavity, the receiving cavity is provided with a guide cone, and the guide cone realizes the guiding installation of the base top part; the lower tooling 5 is composed of a lower tooling seat body and a positioning frame, the positioning frame is accommodated in the lower tooling seat body, the top of the positioning frame is provided with a positioning groove, and the base part 1 is detachably arranged in the positioning groove, so as to realize the positioning of the base part 1; that is, the upper tooling 4 and the lower tooling 5 realize the guiding and positioning of the base part 1 and the base top part 3 before installation and during the assembly process. In the assembly process, preferably, the pressing pressure applied by the upper tooling 4 and the lower tooling 5 is 300-10000N.
[0022] In order to further ensure the assembly quality, a QR code is also printed on the surface of the base part 1, the intermediate connector 2 and the base top part 3 by laser, and the QR code is used to track the change of the interference fit pressing pressure during processing. The QR code stores the detailed information of the corresponding part, including the pressing pressure threshold range, manufacturer information, and production date.
[0023] Specifically, in the process of implementing the interference fit assembly of the parts of the solenoid valve body base by using the upper tooling 4 and the lower tooling 5, the QR code is first scanned by an external pressure monitoring device to read the compression pressure threshold range information, and at the same time, during the assembly process, the pressure monitoring device monitors the compression pressure applied during the assembly process in real time. The compression pressure monitored in real time is compared with the compression pressure threshold range information stored in the QR code. When the compression pressure monitored in real time is not within the set threshold range, an alarm is immediately issued to stop the assembly.
[0024] Furthermore, according to the needs, the pressing pressure data, timestamp and other information applied during the press-fitting process can be stored in real time and entered into the background data system for later use in tracing the quality of the product, thereby tracing and managing the quality of the product. During the press-fitting process, the operator needs to adjust the pressing pressure and speed according to the actual situation to ensure that each part can achieve the best assembly effect, thereby ensuring the assembly quality of the product.
[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
