Description

Technical Field

[0001] This utility model relates to the field of automotive solenoid valve technology, and in particular to a solenoid valve coil, shielding cover, and riveting guide sleeve positioning and mounting device. Background Technology

[0002] EBS (Electronic Braking System) employs an electronic approach to activate all braking system components, achieving braking consistency between the tractor and trailer, providing comfortable deceleration control, and enabling continuous self-testing through integrated diagnostic and monitoring functions. The EBS system includes brake signal sensors, a central controller (ECU), proportional relay valves, a rear axle adjuster, ABS solenoid valves, trailer control valves, wheel speed sensors, and brake pad wear sensors. These components collectively form the core of the EBS system, enabling electronically controlled braking. The standardization and high integration of EBS system components are crucial for reducing production and installation costs and improving vehicle economy. Solenoid valve coils and shields are important components of valve products. During installation, multiple coils must be manually pressed into the shield one by one, and then the riveting guide sleeves connecting the coils and shields must be pressed into the center through-hole of the coil and the positioning hole of the shield one by one to install the coil inside the shield. Manual assembly is time-consuming and labor-intensive, and cannot guarantee the stability and quality of the installed product. Therefore, it is necessary to standardize and integrate the production of solenoid valve coils and shields to improve the reliability of the installation between the shield and the coil. Summary of the Invention

[0003] This utility model provides a positioning and installation device for an electromagnetic valve coil, a shield, and a riveting guide sleeve. This device can simultaneously press multiple coils into the shield and press multiple riveting guide sleeves from both sides into the central through holes of multiple coils and the positioning holes of the shield, thereby connecting the coils and the shield. The positioning and installation of the coils, shield, and riveting guide sleeves are all automated through a controller, resulting in high installation efficiency, saving labor costs, and high consistency and qualification of installation.

[0004] The technical solution adopted to achieve the above-mentioned objectives of this utility model is as follows:

[0005] A positioning and installation device for an electromagnetic valve coil, shield, and riveting guide sleeves is disclosed. This device positions and installs the shield, multiple coils, and multiple riveting guide sleeves. The device includes a mounting plate, an upper cylinder, an upper pressure block, a left cylinder, a left pressure block, a right cylinder, and a right pressure block. The mounting plate has a shield limiting groove, on which the shield is secured. Multiple coils are secured above the shield's installation position. Each coil has a central through hole connecting its two ends. The shield has corresponding positioning holes on both sides of the coil installation location. Multiple riveting guide sleeves are inserted into the positioning holes, but none of them penetrate the shield. The upper cylinder, left cylinder, and right pressure block... All right cylinders are fixed to the mounting plate, and the piston rod of the upper cylinder is vertically downward toward the shielding cover limiting groove. The piston rods of the left and right cylinders are horizontally toward the shielding cover limiting groove from the left and right sides, respectively. The upper pressure block, left pressure block, and right pressure block are fixed to the piston rod ends of the upper, left, and right cylinders, respectively. The upper cylinder moves down, so that the upper pressure block presses on multiple coils, pressing multiple coils into the shielding cover at the same time. The left and right cylinders move towards the middle, so that the left and right pressure blocks press on the riveting guide sleeves on the left and right sides of the shielding cover, respectively, pressing multiple riveting guide sleeves into the central through holes of multiple coils and the positioning holes of the shielding cover from both sides, thereby realizing the positioning and installation of coils, shielding cover, and riveting guide sleeves.

[0006] The upper pressure block has pressure plates fixedly connected to both sides of its bottom. When the upper pressure block moves down to be close to the coil, the pressure plates on both sides of the bottom of the upper pressure block press on the upper sides of the multiple coils respectively.

[0007] Each coil has a positioning boss fixedly connected to the upper part of one end. When the coil is installed inside the shielding cover, the positioning boss just presses against the upper surface of the shielding cover, and the center line of the central through hole of the coil coincides with the center line of the positioning hole of the shielding cover.

[0008] The bottom of the pressure plate at one end of the positioning boss on the coil is provided with a positioning groove that matches the upper contour of the positioning boss, and the bottom of the pressure plate at the other end is provided with an arc-shaped groove that matches the upper contour of the coil.

[0009] The center lines of the left cylinder, the right cylinder, and the shielding cover limiting groove are on a straight line.

[0010] The bottom contour of the shielding cover matches the structure of the shielding cover limiting groove.

[0011] Positioning posts are provided at intervals on the side of the left and right pressure blocks facing the shielding cover limiting groove. The number and position of the positioning posts on the left and right pressure blocks match the number and position of the positioning holes on the shielding cover.

[0012] The mounting plate is also equipped with three displacement sensors, which monitor the movement of the upper pressure block, left pressure block, and right pressure block, respectively.

[0013] The positioning and installation device also includes a controller, which is connected to the upper cylinder, the left cylinder, the right cylinder and three displacement sensors respectively. The controller controls the movement of the upper cylinder, the left cylinder and the right cylinder respectively, and receives the movement stroke monitored by the three displacement sensors respectively, and determines whether the movement stroke is qualified, thereby determining whether the installation of the coil, the shielding cover and the riveting guide sleeve is qualified.

[0014] An outer cover is connected to the mounting plate, which covers the mounting plate, the upper cylinder, the left cylinder, and the right cylinder. A human body sensor is installed on the inner wall of the outer cover. The human body sensor is connected to the controller. The human body sensor receives a signal of a person approaching and transmits the signal to the controller. The controller performs early warning and shutdown operations based on the received signal.

[0015] Compared with the prior art, the positioning and installation device for the solenoid valve coil, shield, and riveting guide sleeve provided by this utility model has the following advantages: 1. The positioning and installation device for the solenoid valve coil, shield, and riveting guide sleeve provided by this utility model can press multiple coils into the shield at the same time, and press multiple riveting guide sleeves into the central through holes of multiple coils and the positioning holes of the shield from both sides, thereby connecting the coil and the shield. Moreover, the positioning and installation of the coil, shield, and riveting guide sleeve are all automated through the controller, which has high installation efficiency, saves labor costs, and has high installation consistency and qualification.

[0016] 2. The solenoid valve coil, shielding cover and riveting guide sleeve positioning and installation device provided by this utility model are equipped with displacement sensors to monitor the downward stroke displacement of the coil and the left or right pressure stroke displacement of the riveting guide sleeve. The installation position can be judged based on the stroke displacement, without the need for manual inspection.

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] The solenoid valve coil, shield, and riveting guide sleeve positioning and mounting device provided in this embodiment can position and mount the shield, multiple coils, and multiple riveting guide sleeves. The structures of the shield 1, coil 2, and riveting guide sleeve 3 are as follows: Figures 1-2As shown, the shielding cover is shaped like an inverted U-shape, including a base plate 101 and side plates 102 vertically connected to both sides of the base plate. In this embodiment, three coils are installed side by side inside each shielding cover. Shielding cover positioning holes 103 are provided on both sides of the coil mounting location on the side plates, meaning each shielding cover has six positioning holes. Specifically, each coil has a central through hole 202 connecting both ends of the coil. A positioning boss 201 is fixedly connected to the upper part of one end of each coil. When the coil is installed inside the shielding cover, the positioning boss presses against the upper surface of the shielding cover (i.e., on the side plate), and the center line of the central through hole of the coil coincides with the center line of the positioning hole of the shielding cover. The riveting guide sleeve passes through the positioning hole of the shield and the central through hole of the coil, thereby connecting the coil and the shield. Specifically, six riveting guide sleeves are provided, each including a connected positioning sleeve and a positioning ring. The outer diameter of the positioning ring is larger than the outer diameter of the positioning sleeve. The central through hole of the coil, the positioning hole of the shield, and the outer diameter of the positioning sleeve are the same. The positioning sleeve of the riveting guide sleeve passes through the positioning hole of the shield and the central through hole of the coil, thereby connecting the coil and the shield. Furthermore, the positioning boss has a trapezoidal structure.

[0029] The solenoid valve coil, shielding cover, and riveting guide sleeve positioning and mounting device provided in this embodiment includes a mounting plate 4, an upper cylinder 502, an upper pressure block 503, a left cylinder 601, a left pressure block 602, a right cylinder 701, and a right pressure block 702. Figure 3 and Figure 4 As shown. In this embodiment, the mounting plate is provided with a shielding cover limiting groove 401, mounting slide grooves 402 located on both sides of the shielding cover limiting groove for mounting the left cylinder and the right cylinder respectively, and a displacement sensor mounting groove 403 located behind the two mounting slide grooves. Its structure is as follows. Figure 5 As shown. Before installing the shielding cover, multiple coils, and riveting guide sleeve, first place the shielding cover in the shielding cover limiting groove, then place the coils above the shielding cover installation position, and insert the riveting guide sleeve into the shielding cover positioning hole, but do not insert the riveting guide sleeve into the shielding cover. Figure 6 As shown, this avoids affecting the coil pressing inside the shielding cover; specifically, the structure of the shielding cover limiting groove matches the bottom structure of the shielding cover to ensure that the shielding cover can be snapped into the shielding cover limiting groove.

[0030] In this embodiment, the upper cylinder, left cylinder, and right cylinder are all fixed on the mounting plate. The piston rod of the upper cylinder is vertically downward toward the shielding cover limiting groove, and the piston rods of the left and right cylinders are horizontally toward the shielding cover limiting groove from the left and right sides, respectively. Specifically, the upper cylinder is fixedly mounted on the mounting plate by the support frame 501, that is, the support frame is fixedly mounted on the mounting plate, the upper cylinder is vertically downward fixed on the support frame, and the left and right cylinders are horizontally fixed in the two mounting grooves of the mounting plate, respectively.

[0031] The upper, left, and right pressure blocks are fixed to the piston rod ends of the upper, left, and right cylinders, respectively. The upper cylinder moves downwards, pressing the upper pressure block onto multiple coils, simultaneously pressing the coils into the shielding cover. The left and right cylinders move towards the center, pressing the left and right pressure blocks onto the riveting guide sleeves on the left and right sides of the shielding cover, respectively. This presses the riveting guide sleeves into the central through holes of the multiple coils and the positioning holes of the shielding cover, thus achieving the positioning and installation of the coils, shielding cover, and riveting guide sleeves. Specifically, pressure plates 5031 are fixedly connected to both sides of the bottom of the upper pressure block. When the upper pressure block moves downwards close to the coils, the pressure plates on both sides of the bottom of the upper pressure block press onto the upper sides of the multiple coils, such as... Figure 7 and Figure 8 As shown; furthermore, the bottom of the pressure plate at one end of the positioning boss on the coil is provided with a positioning groove 5032 that matches the upper contour of the positioning boss, and the bottom of the pressure plate at the other end is provided with an arc-shaped groove 5033 that matches the upper contour of the coil, as shown. Figure 8 As shown, the number of positioning slots and arc-shaped slots is the same as the number of coils. That is, each upper pressure block has three positioning slots and three arc-shaped slots at its bottom. When the upper pressure block presses on multiple coils, the three positioning slots press on the positioning bosses of the three coils respectively, and the three arc-shaped slots press on the ends of the three coils away from the positioning bosses respectively. In this application, the shielding cover is first positioned by the shielding cover limiting slot, and then the coil is positioned by the positioning slots. As long as the positions of the upper pressure block and the shielding cover limiting slot do not shift, the accuracy of the coil's position inside the shielding cover can be ensured, avoiding displacement when the coil is pressed down. Moreover, in this application, the upper pressure block presses down on the coil from both sides, ensuring that the force on both sides of the coil is uniform when it is pressed down.

[0032] Preferably, the center lines of the left cylinder, the right cylinder, and the shielding cover limiting groove are aligned. Further, positioning posts are spaced apart on the side of the left and right pressure blocks facing the shielding cover limiting groove. The number and position of the positioning posts on the left and right pressure blocks match the number and position of the shielding cover positioning holes; that is, three left positioning posts 603 are spaced apart on the left pressure block, and three right positioning posts 703 are spaced apart on the right pressure block. When the left and right pressure blocks move towards the center, the three left positioning posts penetrate the three left riveting guide sleeves and into the three shielding cover positioning holes on the left side of the shielding cover and the central through holes of the three coils. The three right positioning posts penetrate the three right riveting guide sleeves and into the three shielding cover positioning holes on the right side of the shielding cover and the central through holes of the three coils, ensuring that the concentricity of the shielding cover and the coils remains highly consistent. The left and right pressure blocks continue to move towards the center, pressing the riveting guide sleeves into the central through holes of the coils. Preferably, the diameter of the left and right positioning posts is less than or equal to the diameter of the through holes on the riveting guide sleeves.

[0033] In this embodiment, three displacement sensors 8 are also installed on the mounting plate. The three displacement sensors monitor the movement stroke of the upper pressure block, the left pressure block, and the right pressure block, respectively. Figure 4 Specifically, the displacement sensor for monitoring the upper pressure block is mounted on the support frame, and the displacement sensors for monitoring the left and right pressure blocks are respectively mounted on the displacement sensor mounting slots on the left and right sides of the mounting plate. In this embodiment, an outer cover box 9 is also connected to the mounting plate, which covers the mounting plate, the upper cylinder, the left cylinder, and the right cylinder. See [link to documentation]. Figure 3 Specifically, the outer casing is made of transparent acrylic material. Human body sensors 10, such as infrared sensors and grating sensors, are installed on the inner wall of the outer casing.

[0034] The solenoid valve coil, shield, and riveting guide sleeve positioning and installation device provided in this embodiment also includes a controller. The controller is connected to the upper cylinder, left cylinder, right cylinder, three displacement sensors, and a human body sensor. The controller controls the movement of the upper cylinder, left cylinder, and right cylinder, and receives the movement stroke monitored by the three displacement sensors. It determines whether the movement stroke is qualified, thereby determining whether the installation of the coil, shield, and riveting guide sleeve is qualified. The human body sensor receives a human body approach signal and transmits the signal to the controller. The controller performs early warning and shutdown operations based on the received signal.
