Description

Technical Field

[0001] This invention relates to the field of mechanical tooling technology, and in particular to an external dual CDC solenoid valve positioning angle tooling. Background Technology

[0002] The external dual CDC solenoid valve is an electromagnetic control valve body with dual independent fluid control functions. As a core component of precision fluid control equipment such as air suspension and hydraulic control systems, it achieves precise adjustment of fluid on / off and flow rate through precise angle control of dual-sided coil assemblies. It is widely used in scenarios with extremely high requirements for valve body assembly precision, such as automotive chassis suspension and industrial precision hydraulic equipment.

[0003] In existing technologies, the coil assembly of external dual CDC solenoid valves is mostly completed manually. After aligning the coil terminals with the valve body, the coil nut is tightened directly with a wrench. Installation and debugging often face problems of low accuracy and efficiency. Therefore, the market urgently needs a new type of tooling that can simplify the operation process and improve the accuracy of installation and debugging. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a positioning angle tooling for an external dual CDC solenoid valve, which solves the problems of low coil assembly accuracy and efficiency of the external dual CDC solenoid valve.

[0005] The present invention also provides a positioning angle fixture for an external dual CDC solenoid valve, comprising: a base plate, a scale plate fixedly connected to the upper middle part of the base plate, an angle sleeve provided at the center of the scale plate, and a pointer fixedly connected to the outer surface of the angle sleeve, the pointer cooperating with the scale of the scale plate; The base plate, scale, angle sleeve and pointer are provided in two sets. The lower side of the two sets of base plates are fixedly connected to a track. The outer surface of the track is slidably connected to a square flange linear bearing. The outer surface of the square flange linear bearing is fixedly connected to a base. A solenoid valve limiting block is hinged to one side of the base, and a quick clamp is installed between the other side of the base and the solenoid valve limiting block. The solenoid valve body is clamped between the base and the solenoid valve limiting block. The solenoid valve body includes coil terminals on both sides, and the coil terminals are located between two sets of angle sleeves.

[0006] Preferably, the surfaces of the base and the solenoid valve limiting block used to fit the solenoid valve body are arc-shaped. An anti-slip pad is provided on the inner side of the arc-shaped surface. The arc-shaped surface fits the outer contour of the cylindrical solenoid valve body, greatly increasing the contact area and making the clamping force more uniform. The inner anti-slip pad can increase the friction between the valve body and the clamping surface, effectively preventing the solenoid valve body from slipping during assembly, ensuring positioning accuracy, and at the same time forming a flexible contact to avoid scratches and damage caused by direct contact between the hard clamping surface and the valve body.

[0007] Preferably, a positioning block is fixedly connected to the inner side of the base, and a protrusion is provided on the upper surface of the positioning block. The fixed connection between the positioning block and the base ensures the stability of the positioning structure and prevents it from loosening or shifting. The protrusion on the upper surface can cooperate with the positioning hole of the solenoid valve body to limit the solenoid valve body on the base, completely restricting the displacement and rotation of the valve body, so that the position of the solenoid valve body is fixed after clamping, ensuring that the coil terminal and the engagement groove of the angle sleeve are aligned, simplifying the alignment operation during clamping, reducing the difficulty of manual alignment, and improving clamping efficiency.

[0008] Preferably, the outer surface of the solenoid valve body is provided with a positioning hole, which engages with the protrusion of the positioning block. The engagement of the positioning hole and the protrusion forms a positioning mechanism, which can effectively prevent the valve body from shifting due to external force during assembly and ensure the accuracy of angle positioning. The engagement structure makes the clamping and alignment of the solenoid valve body more intuitive and convenient. The operator only needs to align the positioning hole with the protrusion to complete the initial positioning of the valve body, without the need for repeated adjustments, which greatly shortens the clamping time.

[0009] Preferably, the outer surface of the base plate is rotatably connected to the angle sleeve. The side of the angle sleeve away from the base plate is provided with a locking groove. The rotatable connection between the angle sleeve and the base plate allows the angle sleeve to be flexibly adjusted to adapt to different angle requirements in the drawings. The locking groove on the side away from the base plate provides a locking position for the solenoid valve coil terminal, allowing the terminal to be accurately inserted. This enables the preset angle of the angle sleeve to be directly transmitted to the coil terminal, indirectly achieving the angle positioning of the solenoid valve coil.

[0010] Preferably, the position of the engaging groove corresponds to the position of the coil terminal, and the shape of the engaging groove matches the shape of the coil terminal. The engagement groove and the coil terminal are positioned and matched, which can achieve precise engagement between the two, so that the angle between the solenoid valve coil and the angle sleeve is consistent, reducing angle deviation. The tight engagement structure prevents relative rotation between the terminal and the engaging groove, so that the coil will not shift in angle during the process of tightening the coil nut, ensuring the angle accuracy after tightening.

[0011] Preferably, the outer surface of the base plate is provided with an arc-shaped opening, and the side of the angle sleeve near the base plate is provided with an internal thread locking hole. The arc-shaped opening on the base plate is adapted to the rotation trajectory of the angle sleeve. During the adjustment of the angle sleeve, the internal thread locking hole can move flexibly along the arc-shaped opening, without limiting the angle adjustment range of the sleeve, and adapting to different angle assembly requirements. The internal thread locking hole on the angle sleeve provides a screw-in point for external fasteners, and the threaded internal thread locking hole can achieve a firm fit with the bolt.

[0012] Preferably, the position of the arc-shaped opening corresponds to the position of the internal thread locking hole, and the arc-shaped opening exposes the position of the internal thread locking hole. The internal thread locking hole is used to lock and fix the angle sleeve at a set angle position. The arc-shaped opening corresponds to the position of the internal thread locking hole, and the internal thread locking hole is exposed, allowing external bolts to easily pass through the arc-shaped opening and screw into the internal thread locking hole. The locking operation is simple and convenient, greatly shortening the angle fixing time. The exposed internal thread locking hole allows the operator to see the locking position intuitively, reducing human operation errors.

[0013] Preferably, there are two tracks, located on both sides of the base. The tracks are used for position adjustment of the base. The two tracks are symmetrically arranged on both sides of the base, which can provide double-sided support and guidance for the base, making the base slide more smoothly and avoiding tilting during the sliding process. This ensures that the base drives the solenoid valve body to move smoothly and ensures that the coil terminal can be accurately aligned with the locking groove of the angle sleeve, thereby improving the accuracy of the coil terminal being embedded in the locking groove.

[0014] Preferably, the quick clamp is used to press and position the solenoid valve body with the solenoid valve limiting block, and the angle sleeve is used to achieve high-precision installation of the solenoid valve body. The quick clamp can quickly drive the solenoid valve limiting block to press the solenoid valve body, realizing quick clamping and loosening of the valve body. The operation is simple and convenient, without the need for complex tools, which greatly shortens the clamping and disassembly time and improves the overall assembly efficiency. The angle sleeve provides precise angular positioning for the solenoid valve body, realizing high-precision engagement and positioning of the coil terminals, controlling the installation angle of the valve body within the range required by the drawings, and greatly improving the installation accuracy of the solenoid valve.

[0015] Compared with the prior art, the present invention provides an external dual CDC solenoid valve positioning angle fixture, which has the following beneficial effects: 1. By setting the dial, angle sleeve and pointer, high-precision positioning of the angle of the double coils of the solenoid valve can be achieved, thereby improving the assembly accuracy of the solenoid valve.

[0016] 2. By adapting the locking groove of the angle sleeve to the coil terminal, precise locking and positioning of the coil terminal and the locking groove can be achieved. Moreover, it can be plugged in and unplugged, making the operation convenient and quick, and improving assembly efficiency.

[0017] 3. By setting up the base, solenoid valve limit block, positioning block protrusion and solenoid valve body positioning hole, the solenoid valve body can be accurately clamped and positioned, reducing the slippage of the valve body during clamping. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This invention discloses an external dual CDC solenoid valve positioning angle fixture, comprising: a base plate 1, a bearing scale 2, an angle sleeve 3, etc. The two angle positioning structures are connected as a whole through a fixed connection between the lower side and a rail 5, ensuring the stability of the fixture. Its rigid structure provides a stable installation and support benchmark for each component. The scale 2, a circular disc structure with 360° continuous angle graduations, is fixedly connected to the upper center of the base plate 1. In conjunction with a pointer 4, it indicates the angle adjustment of the angle sleeve 3. The operator can adjust the angle according to the scale. The angle sleeve 3 is precisely adjusted to the preset angle shown in the drawing. Angle sleeve 3 is positioned at the center of the scale 2 to achieve precise engagement and positioning of the coil terminal of the solenoid valve body 11, indirectly limiting the installation angle of the solenoid valve coil. After the angle is adjusted to the correct position, it is locked in place by the engagement of the internal thread locking hole 301 and the external bolt. A pointer 4 is fixedly connected to the outer surface of the angle sleeve 3, with one end fixedly connected to the outer surface of the angle sleeve 3 and the other end serving as the indicator, opposite to the scale surface of the scale 2. The pointer 4 rotates synchronously with the rotation of the angle sleeve 3. The rotation of the angle sleeve 3 is converted into precise scale values, allowing operators to quickly and accurately adjust the angle. The pointer 4 matches the scale of the dial 2. The outer surface of the base plate 1 is rotatably connected to the angle sleeve 3. The outer surface of the base plate 1 is provided with an arc-shaped through-hole 101, the position of which corresponds to the internal thread locking hole 301 of the angle sleeve 3. The through-hole size is adapted to the passage of the external locking bolt, and the arc trajectory matches the rotation trajectory of the angle sleeve 3. The side of the angle sleeve 3 closest to the base plate 1 is provided with an internal thread locking hole 301, through which the external bolt passes. 01 Screw into the internal thread locking hole 301. The bolt head presses against the outer surface of the base plate 1. By using the locking force of the thread and the friction between the bolt and the base plate 1, the relative rotation between the angle sleeve 3 and the base plate 1 is restricted, thereby achieving angle locking of the angle sleeve 3. The position of the arc-shaped through-hole 101 corresponds to the position of the internal thread locking hole 301, and the arc-shaped through-hole 101 exposes the position of the internal thread locking hole 301. The internal thread locking hole 301 is used to lock and fix the angle sleeve 3 at the set angle position. The angle sleeve 3 is used to achieve high-precision installation of the solenoid valve body 11. The base plate 1, dial 2, angle sleeve 3, and pointer 4 constitute the angle positioning structure of the tooling. The dial 2 provides a scale for angle adjustment. The angle sleeve 3 can rotate around the base plate 1 at the center of the dial 2. During the rotation, it drives the pointer 4 to rotate as well, achieving precise angle indication. The arc-shaped through-hole 101 on the base plate 1 corresponds to the internal thread locking hole 301 of the angle sleeve 3, and the arc-shaped through-hole 101 protrudes from the internal thread locking hole 301, making it easy for external fasteners to pass through the internal thread locking hole 301 and lock the angle sleeve 3 at the set angle required by the drawing, preventing the angle sleeve 3 from shifting. The angle sleeve 3 provides precise angle support for the coil terminals on the left and right sides of the solenoid valve body 11, achieving high-precision installation and positioning of the solenoid valve body 11 and ensuring the accuracy of the angle installation of the dual CDC solenoid valve.

[0022] Reference Figure 1 , Figure 4 , Figure 7 and Figure 8 A solenoid valve limiting block 8 is hinged to one side of the base 7. Through this hinge structure, the clamping space can be opened and closed by rotating around the hinge point, facilitating the insertion and removal of the solenoid valve body 11. When the quick clamp 9 is driven to press down towards the base 7, its arc-shaped surface tightly fits the outer contour of the solenoid valve body 11, achieving pressure and limiting of the solenoid valve body 11. A quick clamp 9 is installed between the other side of the base 7 and the solenoid valve limiting block 8, driving the solenoid valve limiting block 8 to quickly press or release the solenoid valve body 11. This is a manual quick clamping mechanism. The lower end of its hook structure is rotatably connected to the base 7, and the upper end of the hook structure engages with the solenoid valve limiting block 8. This is an existing mechanism. The solenoid valve body 11 is clamped between the base 7 and the solenoid valve limiting block 8. This is a core component of fluid control and is an existing device, mainly composed of a double valve body, coil assembly, and terminals, utilizing the principle of electromagnetic induction. The control valve core movement realizes fluid on / off and flow regulation. The two sides of the solenoid valve body 11 include coil terminals. The coil terminals are located between two sets of angle sleeves 3. The surfaces of the base 7 and the solenoid valve limiting block 8 that are used to fit the solenoid valve body 11 are arc-shaped. The inner side of the arc-shaped surface is provided with anti-slip pads. The side of the angle sleeve 3 away from the base plate 1 is provided with a locking groove 302. The groove shape is adapted to the shape of the solenoid valve coil terminal. After the coil terminal is locked into the locking groove 302, its rotation is restricted. The operator can directly tighten the coil nut to ensure that the coil installation angle is within the preset angle range. The position of the locking groove 302 corresponds to the position of the coil terminal. The shape of the locking groove 302 matches the shape of the coil terminal. The quick clamp 9 is used to make the solenoid valve limiting block 8 press and position the solenoid valve body 11. The base 7, solenoid valve limiting block 8, and quick clamp 9 constitute the clamping and fixing structure of the tooling. The quick clamp 9 allows the solenoid valve limiting block 8 to rotate around the hinge point, realizing quick clamping and loosening of the solenoid valve body 11, which is convenient to operate and securely clamped. The arc-shaped mating surface of the base 7 and the solenoid valve limiting block 8 is adapted to the outer contour of the solenoid valve body 11. With the anti-slip rubber pad on the inner side of the arc-shaped surface, it avoids bumping and damage to the solenoid valve body 11 during clamping. The engaging groove 302 on the side of the angle sleeve 3 away from the base plate 1 engages with the solenoid valve body 11. The coil terminal of the valve body 11 is adapted. After the coil terminal is inserted into the locking groove 302, the angle between the coil terminal and the angle sleeve 3 is kept consistent. Use a special wrench to tighten the solenoid valve coil nut to lock the angle between the coil and the solenoid valve body 11. The coil terminal is a metal wire protruding from the coil body. The locking groove 302 locks the coil terminal, indirectly fixing the angle of the coil. Then tighten the lock nut to fix the coil on the solenoid valve body 11, so that the angle of the left and right coils meets the requirements of the drawing.

[0023] Reference Figure 6 , Figure 7 and Figure 8The base plate 1, dial 2, angle sleeve 3, and pointer 4 are provided in two sets. Two tracks 5 are symmetrically fixedly connected to the lower sides of the two sets of base plates 1, forming horizontal guide tracks 5. These tracks provide horizontal guidance for the square flange linear bearing 6 and the base 7, satisfying the left and right movement requirements of the solenoid valve body 11 and preventing the base 7 from shifting position during movement. The square flange linear bearing 6 is slidably connected to the outer surface of the track 5, fitted onto the outer surface of the track 5, and contains ball bearings that cooperate with the track 5, reducing the sliding friction between the base 7 and the track 5, significantly reducing movement resistance, allowing the operator to easily push the base 7 to move, and enabling the base 7 to slide smoothly along the track 5. The outer surface of the square flange linear bearing 6 is fixedly connected to the base 7, forming an openable clamping space through hinged engagement with the solenoid valve limit block 8. This, combined with the quick clamp 9, enables the rapid clamping and releasing of the solenoid valve body 11, while simultaneously allowing the square flange linear bearing 6 to slide smoothly along the track 5. The flange linear bearing 6 moves along the track 5, driving the solenoid valve body 11 to adjust its left and right positions. The inner side of the base 7 is fixedly connected to the positioning block 10, which realizes the precise positioning of the solenoid valve body 11 on the base 7, restricts the displacement of the solenoid valve body 11, and ensures that the position of the solenoid valve body 11 is fixed after clamping, so that the coil terminal of the solenoid valve body 11 is aligned with the engagement groove 302 of the angle sleeve 3. The upper surface of the positioning block 10 is provided with a protrusion, and the outer surface of the solenoid valve body 11 is provided with a positioning hole 1101, which is a concave hole structure. The shape and size of the concave hole are adapted to the protrusion of the positioning block 10, and can form a tight engagement with the protrusion, restricting the displacement of the solenoid valve body 11 and ensuring the accuracy of the clamping position. The positioning hole 1101 of the solenoid valve body 11 engages with the protrusion of the positioning block 10. There are two tracks 5, which are located on both sides of the base 7 respectively. The tracks 5 are used for the position adjustment of the base 7. The two sets of angle positioning structures are connected as a whole by the rails 5. There are two rails 5, which are symmetrically distributed on both sides of the base 7. They provide guidance and support for the sliding of the square flange linear bearing 6. The square flange linear bearing 6 drives the base 7 to slide along the rails 5, realizing the position adjustment of the base 7 and the clamped solenoid valve body 11. This allows the coil terminals on both sides of the solenoid valve body 11 to be engaged one by one into the two left and right engagement slots 302 for angle positioning. The positioning block 10 on the inner side of the base 7 and its protrusion engage with the positioning hole 1101 on the outer surface of the solenoid valve body 11, further restricting the displacement of the solenoid valve body 11. This ensures that the coil terminals on both sides of the solenoid valve body 11 can be accurately aligned with the engagement slots 302 of the two sets of angle sleeves 3, thus ensuring the accuracy of the angle positioning of the coil terminals on both sides of the double CDC solenoid valve.

[0024] The working principle of the above embodiments is as follows: This fixture consists of two base plates 1 on the left and right and two rails 5 forming an overall fixture frame. A 360° scale 2 is installed on the upper center of each of the two base plates 1. An angle sleeve 3 is rotatably connected to the center of the scale 2. A pointer 4 is fixedly connected to the outside of the angle sleeve 3, which together form a double-sided angle positioning structure. Two square flange linear bearings 6 are installed on the two rails 5. A base 7 is fixedly connected to the square flange linear bearings 6. A solenoid valve limit block 8 is installed on the base 7, thus forming a solenoid valve clamping and fixing structure that can slide along the rails 5. In use, first adjust the pointers 4 on both sides of the tooling according to the drawing requirements, so that the pointers 4 are aligned with the scale on the dial 2. Then, use bolts to insert into the arc-shaped through-hole 101 and engage with the internal thread locking hole 301 to lock and fix the angle sleeve 3. After clamping the solenoid valve body 11 between the base 7 and the solenoid valve limit block 8, push the base 7 to slide to the left along the track 5, so that the coil terminal on the left side of the solenoid valve body 11 is engaged in the engagement groove 302 of the left angle sleeve 3. After confirming that the angle meets the drawing requirements, use a special wrench to tighten the left solenoid valve coil nut to fix its angle with the solenoid valve body 11. Then, push the base 7 to slide to the right along the track 5, so that the coil terminal on the right side of the solenoid valve body 11 is engaged in the engagement groove 302 of the right angle sleeve 3. After confirming that the angle meets the drawing requirements again, use a special wrench to tighten the right solenoid valve coil nut to complete the angle fixing of both coils, so that the coil angles on both sides of the solenoid valve body 11 meet the drawing requirements.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
