Description

Technical Field

[0001] This invention relates to the field of solenoid valve manufacturing technology. Specifically, it relates to a semi-automatic press-fitting mechanism for solenoid valve bodies. Background Technology

[0002] As a core component of the vehicle suspension system, the assembly precision and performance of the shock absorber directly determine the ride smoothness, handling stability, and ride comfort of the entire vehicle. The solenoid valve, as a key actuator for adaptive damping adjustment in the shock absorber, has its pressing process being a crucial step in the shock absorber assembly production process.

[0003] Currently, the press-fitting production of solenoid valves for vibration dampers in the industry generally adopts a traditional single-person, single-machine, single-workstation operation mode. This production mode requires multiple independent machines and breaks down the press-fitting operation of the solenoid valves into multiple independent processes, resulting in a fragmented production process with poor continuity. Random sampling is used during the press-fitting process to confirm the results.

[0004] Existing patented technologies and production equipment mostly only enable single-station solenoid valve press-fitting, followed by offline spot checks. However, these production methods still have many technical shortcomings. First, production efficiency is low; a single station can only press-fit a single workpiece at a time, making it impossible to achieve synchronous parallel operation across multiple stations. This results in a slow production cycle and is difficult to adapt to the needs of large-scale, high-volume industrial production. Second, labor costs are high; the entire press-fitting and auxiliary processes require multiple operators to work together, leading to high human involvement. This not only increases the company's labor costs but also introduces subjective differences, making human error more likely and affecting product assembly consistency. Third, multiple independent single machines are scattered, resulting in a large equipment footprint, high overall energy consumption, and the inability to perform online automatic inspection. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to provide a semi-automatic pressing mechanism for solenoid valve bodies, which can effectively solve the problems of low efficiency, large equipment footprint, high energy consumption, single-station pressing only, and inability to achieve online fully automatic detection of pressing results of existing solenoid valve pressing equipment.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A semi-automatic pressing mechanism for an electromagnetic valve body includes two sets of identical pressing fixtures symmetrically distributed. Each pressing fixture includes a frame and a servo press, a press head device, an automatic positioning fixture changing device, a detection device, and a clamping device mounted on the frame. The press head device is located below the servo press and moves horizontally via a first sliding device.

Debris or dust generated during the pressing process is removed by the vacuum cleaner 113 to ensure cleanliness requirements.

[0029] Reference Figure 1 In practice, a housing 200 is installed outside the two sets of pressing fixtures 100.

[0030] In this embodiment, the electric gripper 111b is an E-ELGPRS32-100 type electric gripper, and the pneumatic gripper 111a is an MHZ2-16D2 type pneumatic gripper. The diffuse reflection photoelectric sensor 103b is a PG3-BLD300PB type, the rodless cylinder 109a is an Airtac magnetically coupled rodless cylinder RMH16X400S, the first guide rail 105a, the second guide rail 104a, the third guide rail 109b, the fourth guide rail 106a, and the fifth guide rail 114c are all HGH15CA1R520ZAPI type guide rails, and the first motor 105c, the second motor 104b, the fourth motor 106c, and the fifth motor 114a are all Siemens low-inertia motors. The first electric linear slide 105b, the second electric linear slide 104c, the fourth electric linear slide 106b, and the fifth electric linear slide 114b are all STH8-L10 type electric linear slides with linear guide rails.

[0031] In practical use, all cables, including signal lines and power lines, are connected via cable slings 112. These cables move along with the component during movement, ensuring optimal performance. The invention features two symmetrical pressing fixtures 100, allowing one operator to operate both simultaneously. The servo press 101 is fixed in position, and the three pressing heads 102a move left and right via a first sliding device 105 (compared to...). Figure 7 (The same applies below). The pressing parts on the pressing head 102a are different. According to the specific pressing requirements, the required pressing head 102a is moved to be directly below the servo press 101. At the same time, the tooling processing position 103a moves left and right through the second sliding device 104, so that the required tooling processing position 103a is moved to be directly below the pressing head 102a. At this time, the servo press 101 can press the workpiece on the tooling processing position 103a by pressing the pressing head 102a. After pressing, the workpiece is checked by the detector 109c to see if it is qualified. If it is qualified, it is assembled on the tooling processing position 103a. The specific work is as follows: Reference Figure 7 The six tooling processing stations 103a from left to right are defined as station A, station B, station C, station D, station E, and station F. Station E is the inspection station. The four parts of the workpiece are manually placed into station A, station B, station C, and station D respectively. The workpieces in station B and station C are separate and need to be pressed. At this time, station B and station C are moved to the bottom of the pressing head 102a in sequence by the sliding device. The servo press 101 is started to press the workpieces in station B and station C in sequence. Then, the workpiece in station A is picked up by the gripper device 111 and placed on station D. Station D is moved to the bottom of the pressing head 102a. The servo press 101 is started to press the two together. Then, the workpiece in station A is picked up by the gripper device 111 and placed on station F to wait.

[0032] After the workpiece at station C is pressed, it is clamped by the gripper device 111 and placed on station E for inspection. After passing the inspection, the workpiece pressed at station B is clamped by the gripper device 111 and placed on station E. Then, the two are clamped together by the gripper device 111 and placed on station F. Then, station F is moved to below the pressure head 102a by the sliding device. The servo press 101 is started to press the parts on station F together, which is the finished solenoid valve assembly.

[0033] When a workpiece is placed on the tooling processing station 103a, a diffuse reflection photoelectric sensor 103b detects whether the workpiece is properly and correctly placed on each tooling processing station 103a. If the workpiece is not properly placed or incorrectly placed, the machine will not start. When the workpiece needs to be pressed, the cylinder assembly 117 lifts upward to hold the workpiece, serving both a positioning function and a pressure transmission function.

[0034] In this embodiment, all electrical or pneumatic components are connected to a controller, such as a PLC controller, to achieve automatic control.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
