Description

Technical Field

[0001] The invention belongs to the technical field of shock absorbers, and in particular relates to a connector spray paint protection tooling. Background Art

[0002] During the painting process of the shock absorber, the protection of the connector is an important link. The connector of the shock absorber, especially the mounting surface, does not need to be painted, so these parts must be effectively protected during painting. The commonly used protection method is to use a nylon sleeve to protect the connector shaft. However, this traditional protection method has some significant problems.

[0003] First, there is a gap between the end face of the nylon sleeve and the shock absorber product, and the paint mist generated during the painting process may enter through these gaps, thereby contaminating the connector. This contamination not only affects the appearance quality of the product, but may also have a certain impact on its function, especially in precision assembly, which will cause additional cleaning and finishing work, increasing production costs.

[0004] Secondly, due to the variety of types and shapes of shock absorber connectors, in order to adapt to different shapes of connectors, corresponding nylon sleeves must be made for each type and specification of connectors. This diverse demand has led to a wide variety of types and specifications of nylon sleeves, resulting in a large amount of time and space required to store and manage these sleeves in production management. This not only increases storage and management costs, but also reduces production efficiency to a certain extent.

[0005] In summary, the existing shock absorber paint protection method has gaps in the operation process that lead to contamination and complex management of diverse specifications. These problems urgently need to be improved to improve the effect of paint protection and the efficiency of production management. Utility Model Content

[0025] In order to solve the technical problems of low manual assembly efficiency, unstable quality and low yield rate in the installation step of the star-shaped spring sheet during the installation of the shock absorber bottom valve in the prior art, the present application proposes a connector spray paint protection tooling.

[0026] See also Figure 1 , Figure 2 and Figure 3In a possible embodiment, the connector spray paint protection tooling includes: a suspension rope 1, a connecting rod 2, a protective sleeve 3 and a limit block 203; wherein, one section of the length of the two connecting rods 2 connected in an axis forms an X-shaped structure, and one end of the X-shaped structure of the two connecting rods 2 is respectively connected to the two ends of the suspension rope 1; the connecting rods 2 at the other end of the X-shaped structure are respectively connected to the protective sleeve 3 axis; the suspension rope 1 is movably connected to the connecting rod 2; the straight-line distances from the axis connection of the two connecting rods 2 to the central axis of the protective sleeve 3 are equal; the protective sleeve 3 is an internally hollow structure, and the opposite ends of the two protective sleeves 3 have openings, and the two connector shafts 401 of the workpiece 4 are placed at one end of the opening of the protective sleeve 3, and in a horizontal state, the center lines of the two protective sleeves 3 are coaxial; the limit block 203 is set at the connection between the connecting rod 2 and the protective sleeve 3 At axis II 202, at the angle on the opposite side of the opposite surfaces of the two protective sleeves 3, the limit block 203 is connected to the protective sleeve 3 or the connecting rod 2, and the limit block 203 has a right angle. When the protective sleeve 3 is in a horizontal state, the limit block 203 fits the connecting rod 2 and the protective sleeve 3 at the right angle; it also includes: a hanging buckle 101, connecting the hanging rope 1 and the connecting rod 2; and a limit screw 303 and a support block 304, one end of the support block 304 is placed in the protective sleeve 3, and the other end passes through the side wall of the protective sleeve 3 and is sleeved in the limit screw 303 of the side wall of the protective sleeve 3. When the limit screw 303 is rotated, the support block 304 moves toward the center line of the protective sleeve or the side wall of the protective sleeve; the protective sleeve 3 includes a metal sleeve 301 and a protective end face 302, and the protective end face 302 is arranged at the open end of the metal sleeve 301.

[0027] In the above scheme, effective protection of the connector during painting can be achieved by the coordinated use of the lifting rope 1, the connecting rod 2 and the protective sleeve 3. The lifting rope 1 is connected to one end of the X-shaped structure of the connecting rod 2. The protective sleeve can be adjusted to open and close through the movable connection of the lifting rope 1. The connecting rod 2 is connected by an axis to form an X-shaped structure, so that the two protective sleeves 3 can move and fix relative to each other. The limit block 203 provides support and limitation between the protective sleeve 3 and the connecting rod 2 to ensure that the protective sleeve 3 remains horizontal during use. The setting of the limit screw 303 and the support block 304 enables the protective sleeve 3 to adapt to the diameter size of the connector shaft 401 of different workpieces 4 to meet the spray painting clamping of different workpieces. The protective end face 302 is at the open end of the metal sleeve 301 to ensure the sealing between the protective sleeve 3 and the connector shaft 401.

[0028] This embodiment achieves the clamping and protection of the connector during painting by using a combination of a suspension rope 1, a connecting rod 2 and a protective sleeve 3. The design of the X-shaped structure and the limit block 203 allows the protective sleeve 3 to remain stable and horizontal during use. The design of the limit screw 303 and the support block 304 allows the protective sleeve 3 to adapt to connectors of different sizes, and the protective end face 302 provides a better sealing effect. The overall design is simple and easy to operate, which improves work efficiency and reduces human operation errors. At the same time, the combination of the metal sleeve 301 and the protective end face 302 prevents the inner wall of the metal sleeve 301 from being accidentally sprayed with paint mist, ensuring the service life and durability of the protective sleeve 3.

[0029] In a possible implementation manner, the protective end surface 302 is an annular rubber protective strip, which is sleeved on the inner wall of the open end of the metal sleeve 301 to fill the gap between the metal sleeve 301 and the connector shaft 401 .

[0030] In the above scheme, by setting an annular rubber protective strip on the inner wall of the open end of the metal sleeve 301, the gap between the metal sleeve 301 and the connector shaft 401 can be effectively filled, providing a good sealing effect, preventing paint / paint mist from entering the protective sleeve 3 during the painting process, and protecting the connector.

[0031] This embodiment improves the sealing effect of the protective sleeve 3 by using the annular rubber protective strip, prevents paint from entering the interior, and protects the connector. The rubber material has good elasticity and wear resistance, can maintain the sealing effect for a long time, and prolong the service life of the protective sleeve 3. At the same time, the annular design makes installation and replacement more convenient, and improves the use efficiency.

[0032] In a possible implementation manner, the protective end surface 302 is an annular rubber protective sheet, which is sleeved on the open end of the metal sleeve 301 to fill the gap between the metal sleeve 301 and the connector shaft 401 .

[0033] In the above scheme, by setting an annular rubber protective sheet at the open end of the metal sleeve 301, the gap between the metal sleeve 301 and the connector shaft 401 can be effectively filled, providing a good sealing effect, preventing paint from entering the protective sleeve 3 during the painting process, and protecting the connector.

[0034] In this embodiment, the annular rubber protective sheet can be replaced with other elastic materials, such as silicone or polyurethane, to meet different usage requirements. The size and shape of the protective sheet can also be adjusted according to the specific size of the connector to provide a better sealing effect.

[0035] In a possible implementation manner, the suspension rope 1 is a soft steel wire or iron wire.

[0036] In the above scheme, by using soft steel wire or iron wire as the sling rope 1, the load-bearing capacity and durability of the sling rope 1 can be increased while maintaining its flexibility for easy adjustment and use.

[0037] This embodiment improves the load-bearing capacity and durability of the sling 1 by using soft steel wire or iron wire, and adapts to more diverse usage scenarios. The soft steel wire or iron wire material has good flexibility, is easy to adjust and use, and provides a better operating experience.

[0038] In this embodiment, the sling 1 can be replaced with other materials, such as high-strength nylon rope or polyester fiber rope, to meet different usage requirements. The length and diameter of the sling can also be adjusted according to actual conditions to provide better usage effects.

[0039] In a possible implementation manner, when the horizontal connecting head shaft 401 is placed in the protective sleeve 3, the two connecting rods 2 at the other end of the X-shaped structure are parallel.

[0040] In the above solution, by placing a horizontal connecting head shaft 401 in the protective sleeve 3, the two connecting rods 2 at the other end of the X-shaped structure can be kept in a parallel state, providing a more stable support and protection effect.

[0041] This embodiment improves the stability of the protective sleeve 3 by making the two connecting rods 2 at the other end of the X-shaped structure parallel, ensures the stable position of the connecting head during the painting process, prevents paint from entering the interior of the protective sleeve 3, and provides better protection effect.

[0042] In a possible implementation manner, the connecting shaft II 202 is a detachable shaft connection.

[0043] In the above scheme, by adopting the detachable connecting shaft II 202, the protective sleeve 3 can be easily disassembled and replaced, thereby improving the convenience of maintenance and use of the protective sleeve 3 and improving the practicality and applicability of the tooling.

[0044] In a possible implementation manner, the protective sleeve 3 is provided with different apertures.

[0045] In the above solution, by providing protective sleeves 3 with different apertures, connectors of different sizes can be adapted, thereby improving the versatility and adaptability of the tooling and meeting diverse needs.

[0046] A connector spray paint protection tooling according to an embodiment of the present invention is described in detail as follows;

[0047] The connecting rod mechanism is used to convert the product's gravity into horizontal pressure. At the same time, the protective sleeve is always in a horizontal state through the limit device designed on the protective sleeve / metal sleeve, thereby ensuring that the sleeve end face is closely matched with the product plane and plays a good protective role. The tooling consists of three parts, see Figure 1 :

[0048] ① Hoisting part: This part mainly plays the role of fixing and tightening, including the wire rope 1 and the metal structure buckle 101. The wire rope has the characteristics of strong bearing capacity, wear resistance, corrosion resistance, good elasticity and high softness, and can meet the function of tooling suspension and force transmission.

[0049] ②Connecting rod: The connecting rod mainly connects components and transmits transportation force. The connecting rod 2 can convert the pulling force of the hoisting part into horizontal pressure through the connecting shaft Ⅰ201 to ensure that the protective sleeve 3 is tightly pressed on the protective product. The rotatable connection structure of the connecting shaft Ⅱ202 is convenient for easily adjusting the distance between the protective sleeves when installing the protective product. The limit block 203 is used to limit the movement range of the protective sleeve to ensure that the protective sleeve 3 is always in a horizontal state.

[0050] ③ Protective sleeve: This part mainly plays the role of protection and load-bearing. The metal sleeve 301 mainly plays the role of protection and support to prevent the paint from being sprayed onto the part of the workpiece that needs protection. The protective end face 302 is in direct contact with the workpiece. If necessary, a rubber protective sheet can be used to ensure that the tooling and the workpiece mating surface are in close contact to prevent paint mist from penetrating into the protective sleeve and contaminating the workpiece. The limit screw 303 cooperates with the support block 304, see Figure 2 By adjusting the limit screws to control the up and down movement of the support block, it can adapt to workpieces of different sizes, ensure that the center lines of the workpiece and the protective sleeve are on the same line, and ensure that the relative position of the protective end face 302 and the workpiece is correct.

[0051] The specific usage process is as follows, see Figure 3 Assembly diagram: During assembly, first pull the protective sleeve 3 horizontally to a sufficient distance, then place the connecting head shaft 401 of the workpiece 4 in the metal sleeve 301 of the protective sleeve, reset the protective sleeve and tighten the lifting rope 1, under the tension of the lifting rope, the connecting rod 2 generates a clamping force toward the center, so that the protective sleeve 3 moves toward the workpiece and clamps it, and the proximal end of the metal sleeve 301 moves downward under the action of the gravity of the workpiece 4, and when it returns to the horizontal position, it contacts and stops with the limit block 203. At this time, the protective sleeve 3 and the workpiece 4 are tightly fitted together under the action of the double force, and are suspended on the painting station by the lifting rope to complete the assembly action, clamp the workpiece 4 for painting, and the connecting head shaft 401 is protected in the protective sleeve without being painted, and only the workpiece 4 and the workpiece end face 402 are sprayed.

[0052] If a workpiece of a different type is to be replaced, it is only necessary to adjust the limit screw 303 so that the connecting head shaft 401 is located on the center line of the protective sleeve 3, and the type change is convenient and fast.

[0053] 1. The connector spray paint protection tooling of the utility model is added with a connecting rod mechanism, which converts the product's own gravity into a clamping force of the protective sleeve toward the workpiece. The limit block on the connecting rod is used to ensure that the protective sleeve is in a horizontal position with the workpiece, so as to better achieve a close fit between the connector protection tooling and the workpiece, avoid paint spraying to places where paint is not needed, and greatly reduce the time required to clean up the paint later.

[0054] 2. Aiming at the problem of many types and different shapes of joints, the adaptive protective structure of the utility model is designed; support blocks and limit screws are added inside the protective cover, and the height of the support block can be controlled by adjusting the extension length of the screw. The protective cover can be suitable for workpieces of various specifications and automatically adapt to joints of different shapes and sizes. There is no need to make a specific nylon sleeve for each joint, thereby saving a lot of time and space costs.

[0055] 3. In order to ensure the efficiency of the painting process, the protective cover and the connector can be quickly installed and disassembled, easy to operate, and can complete the protection and removal of the joint part in a short time.

[0056] 4. Considering that the protective device needs to be in contact with various chemical paint mists for a long time, corrosion-resistant and wear-resistant metals, rubbers and other materials are selected to manufacture the device to ensure its stability and reliability in long-term use.

[0057] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
