[0002] The main purpose of an electro-hydraulic valve controller is to control a hydraulic system via electrical signals, thereby opening and closing valves and regulating flow. An electro-hydraulic valve controller typically consists of an upper connector with a control panel and a lower base, which are manually pressed together. During the pressing process, the pressing force must be limited to a certain range. Excessive pressing force can easily cause cracking, damaging the base or connector of the electro-hydraulic valve controller. Insufficient pressing force will result in the base and connector not being properly installed.

[0003] In the existing technology, in order to achieve high-precision pressing of two workpieces, on the one hand, due to the special structure of the electro-hydraulic valve controller, it cannot be applied to the installation of the electro-hydraulic valve controller. On the other hand, the existing technologies mostly adopt the reasonable combination of servo motors and guide mechanisms, which has high manufacturing costs and complex structures, and ordinary presses can hardly meet the requirements.

[0004] In response to the shape and high-precision pressing requirements of the base and connector of the electro-hydraulic valve controller, the applicant designed a pressing device suitable for pressing the electro-hydraulic valve controller. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing workpiece pressing technology, such as high cost, complex structure, and difficulty in meeting the requirements of ordinary presses, and to provide a pressing device for an electro-hydraulic valve controller that has a simple structure and can accurately control the pressing force and pressing distance.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a pressing device for an electro-hydraulic valve controller, comprising:

[0007] Fixed base plate;

[0008] A pressing support platform and a bottom mold are fixedly installed on the fixed base plate;

[0009] A pressing cylinder, the cylinder body of which is fixedly mounted on the pressing support platform, and the piston rod of which passes through the pressing support platform and is connected to an upper pressing mold; the upper pressing mold and the bottom pressing mold are arranged correspondingly in the vertical direction.

[0010] A guide assembly, installed on the pressing support platform, is used to guide the movement of the upper mold.

[0011] During pressing, the base of the electro-hydraulic valve controller is placed on the bottom mold, and the connector of the electro-hydraulic valve controller is pre-installed on the upper surface of the base.

[0012] Furthermore, a pressure sensor for real-time detection of the pressing force is provided between the piston rod of the pressing cylinder and the upper mold.

[0013] Furthermore, the guiding component includes:

[0014] At least two linear bearings are symmetrically mounted on the upper surface of the pressing support platform;

[0015] At least two guide posts are provided, which are inserted into the linear bearing; the upper ends of the guide posts are connected by guide frames, and the lower ends of the guide posts are fixedly connected to the upper mold.

[0016] Furthermore, a distance measuring sensor for detecting the moving distance of the upper mold is installed on the guide frame.

[0017] Furthermore, two linear bearings are provided, which are respectively located on both sides of the pressing cylinder, and the lower ends of the two guide pillars are respectively located at both ends of the upper mold, moving vertically along with the upper mold.

[0018] Furthermore, at least one buffer is installed on the pressing support platform.

[0019] Furthermore, the bottom support mold includes a pad fixedly mounted on a fixed base plate, a placement mold fixedly mounted on the pad, and a receiving cavity disposed on the upper surface of the placement mold for accommodating the base of the electro-hydraulic valve controller; wherein,

[0023] The beneficial effects of the pressing device of the electro-hydraulic valve controller of this utility model are:

[0024] This utility model is a pressing device specifically designed for pressing electro-hydraulic valve controllers. An upper pressing mold is installed at the end of the output piston rod of the pressing cylinder, and a bottom mold corresponding to the upper pressing mold is installed on the mounting base plate. When pressing is required, it is only necessary to control the on / off state of the pressing cylinder, and the upper pressing mold is moved and guided by the guide component to realize the pressing of the electro-hydraulic valve controller. The structure is simple, the pressing is reliable, and the investment cost is low.

[0025] Meanwhile, a pressure sensor for real-time detection of the pressing force is installed between the piston rod of the pressing cylinder and the upper pressing mold. A distance sensor for detecting the moving distance of the upper pressing mold is installed on the guide frame. The pressure sensor detects the pressing force between the upper pressing mold and the bottom mold in real time to ensure that the pressing force is controlled within a suitable range during pressing. At the same time, the distance sensor detects the moving distance of the upper pressing mold in real time to achieve precise control of the pressing distance. This avoids the situation where the base or connector of the electro-hydraulic valve controller breaks due to excessive pressing force or excessive pressing distance, or the situation where the base or connector of the electro-hydraulic valve controller is not pressed in place due to insufficient pressing force or insufficient pressing distance.

These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] like Figures 1-4The present invention discloses a specific embodiment of a pressing device for an electro-hydraulic valve controller, comprising a fixed base plate 1, a pressing support platform 2 and a bottom mold 3 fixedly mounted on the fixed base plate 1, a pressing cylinder 4, and a guide assembly 6. The cylinder body 41 of the pressing cylinder 4 is fixedly mounted on the pressing support platform 2, and the piston rod 42 of the pressing cylinder 4 passes through the pressing support platform 2 and is connected to an upper pressing mold 5. The upper pressing mold 5 and the bottom mold 3 are vertically aligned. The guide assembly 6 is mounted on the pressing support platform 2 and is used to guide the movement of the upper pressing mold 5. During pressing, the base 201 of the electro-hydraulic valve controller is placed on the bottom mold 3, and the connector 202 of the electro-hydraulic valve controller is pre-installed on the upper surface of the base 201.

[0034] This embodiment is a pressing device specifically designed for pressing electro-hydraulic valve controllers. An upper pressing mold 5 is installed at the end of the output piston rod of the pressing cylinder 4, and a bottom mold 3 corresponding to the upper pressing mold 5 is installed on the mounting base plate. When pressing is required, it is only necessary to control the on / off state of the pressing cylinder 4, and the upper pressing mold 5 is moved and guided by the guide component 6 to realize the pressing of the electro-hydraulic valve controller. The structure is simple, the pressing is reliable, and the investment cost is low.

[0035] like Figure 2 and Figure 3 As shown, the guide assembly 6 includes at least two linear bearings 61 and at least two guide pillars 62. Specifically, in this embodiment, two linear bearings 61 and two guide pillars 62 are provided. The two linear bearings 61 are symmetrically installed on the upper surface of the pressing support platform 2. The guide pillars 62 pass through the linear bearings 61. The upper ends of the guide pillars 62 are connected by guide frames 63, and the lower ends of the guide pillars 62 are fixedly connected to the upper pressing mold 5. To achieve controllable and precise pressing of the base 201 of the electro-hydraulic valve controller and the connector, in this embodiment, a pressure sensor 7 for real-time detection of the pressing force is provided between the piston rod of the pressing cylinder 4 and the upper pressing mold 5. A distance sensor 8 for detecting the moving distance of the upper pressing mold 5 is installed on the guide frame 63. Two linear bearings 61 are provided, and the two linear bearings 61 are respectively located on both sides of the pressing cylinder 4. The lower ends of the two guide pillars 62 are respectively located at both ends of the upper pressing mold 5 and move with the upper pressing mold 5 in the vertical direction.

[0036] A pressure sensor 7 is installed between the piston rod of the pressing cylinder 4 and the upper pressing mold 5 to detect the pressing force in real time. A distance sensor 8 is installed on the guide frame 63 to detect the moving distance of the upper pressing mold 5. The pressure sensor 7 detects the pressing force between the upper pressing mold 5 and the bottom mold 3 in real time to ensure that the pressing force is controlled within a suitable range during pressing. At the same time, the distance sensor 8 detects the moving distance of the upper pressing mold 5 in real time to achieve precise control of the pressing distance. This avoids the situation where the base 201 or connector 202 of the electro-hydraulic valve controller breaks due to excessive pressing force or excessive pressing distance, or the base 201 or connector 202 of the electro-hydraulic valve controller is not pressed in place due to insufficient pressing force or insufficient pressing distance.

[0037] In this embodiment, at least one buffer 9 is installed on the pressing support platform 2 to reduce the moving speed of the upper mold 5 during pressing. Figure 4 As shown, the bottom mold 3 in this embodiment includes a pad 31 fixedly mounted on a fixed base plate 1, a placement mold 32 fixedly mounted on the pad 31, and a receiving cavity 33 disposed on the upper surface of the placement mold 32 for accommodating the base 201 of the electro-hydraulic valve controller.

The air pump is connected to the air circuit of the pressing cylinder 4, and a pressure regulating valve 10 for adjusting the input air pressure of the pressing cylinder 4 is provided on the air circuit connecting the air pump and the pressing cylinder 4.

[0039] This pressing device uses a distance sensor 8 and a pressure sensor 7 as its core components to precisely control the pressing distance and pressing force between the base 201 and connector 202 of the electro-hydraulic valve controller. The upper pressing mold 5 and the bottom pressing mold 3 work together to press the base 201 and connector 202 of the electro-hydraulic valve controller, ensuring the accurate relative position of the pressing of the base 201 and connector 202 of the electro-hydraulic valve controller. The pressing cylinder 4, the pressure regulating valve 10, the buffer 9, and the distance sensor 8 work together to precisely adjust the pressing speed and pressing distance between the connector 202 and the base 201 of the electro-hydraulic valve controller. The pressing cylinder 4, the pressure regulating valve 10, and the pressure sensor 7 work together to adjust the pressing force between the connector 202 and the base 201 of the electro-hydraulic valve controller within the required range. It should be understood that the pressing device of this embodiment can be installed on the production line to meet the high-precision and high-accuracy pressing requirements between the base 201 and connector 202 of the electro-hydraulic valve controller.

[0040] The pressing device in this embodiment is used as follows: The base 201 of the electro-hydraulic valve controller is placed on the bottom mold 3, and the connector 202 of the electro-hydraulic valve controller is pre-installed on the base 201. The pressing cylinder 4 automatically presses down, the distance sensor 8 automatically detects whether the pressing distance meets the requirements, the pressure sensor 7 automatically detects whether the pressing force is within the pressing requirement range, the pressing cylinder 4 automatically retracts, and the pressing of the base 201 and connector 202 of the electro-hydraulic valve controller is completed.

[0041] This press-fitting device replaces the complex servo feedback for distance signals with a distance sensor 8, and controls the cylinder pressing speed through a pressure regulating valve 10 and a buffer 9. The cylinder, buffer 9, and pressure sensor 7 replace the complex servo displacement and feedback for real-time torque signals, resulting in a simple overall structure and convenient control.
