[0049] The mutual extrusion between the extrusion mechanism and the hook 501 of the present invention can stably realize the installation and fixation of automotive parts, and avoid the instability that the parts are easily shaken when only hanging the parts traditionally.

[0053] Each hanging mechanism 5 includes a hook 501: the hook 501 is used to hang the automotive parts to be painted.

[0054] The extrusion mechanism includes an extrusion driving member (such as the electro-hydraulic rod 502) and a pressing plate 503. The extrusion driving member can drive the movement of the pressing plate 503 to cooperate with the hook 501 to clamp and fix the parts.

[0055] The cooperation between the hook 501 and the extrusion mechanism; the hook 501 is used to hang the parts to be painted.

[0056] The extrusion driving member of the extrusion mechanism (such as the electro-hydraulic rod 502) is connected to the pressing plate 503, and the movement of the driving member drives the movement of the pressing plate 503, so as to realize the clamping and fixing of the parts.

[0057] Through the telescopic adjustment mechanism 2, the height or position of the fixture assembly can be adjusted to meet the painting requirements of different parts.

[0058] The extrusion driving member pushes the pressing plate 503 to move towards the part placement groove of the hook 501. The pressing plate 503 and the hook 501 cooperate with each other to firmly clamp the parts on the hook 501 to avoid shaking during the electrophoretic painting process.

[0059] In the present invention, through the cooperation between the hook 501 and the extrusion mechanism, the stable installation of the parts is realized, the shaking during electrophoretic painting is avoided, and the painting quality is improved.

[0062] In the present invention, the extrusion driving member can be the electro-hydraulic rod 502.

[0063] The telescopic adjustment mechanism 2 can be an electric telescopic rod.

[0064] Further, in the present invention, the hook 501 includes a hook 501 body. The hook 501 body includes a first longitudinal plate 5011, a first transverse plate 5012 and a second longitudinal plate 5013. The first longitudinal plate 5011 is connected to the second longitudinal plate 5013 through the first transverse plate 5012. The first longitudinal plate 5011 and the second longitudinal plate 5013 are arranged parallel to each other, and the first transverse plate 5012 is perpendicular to both the first longitudinal plate 5011 and the second longitudinal plate 5013; the first longitudinal plate 5011, the first transverse plate 5012 and the second longitudinal plate 5013 enclose a part placement groove;

[0065] In the present invention, the first longitudinal plate 5011 serves as the main supporting part of the hook 501, playing a role of bearing and fixing.

[0066] The first horizontal plate 5012 connects the first vertical plate 5011 and the second vertical plate 5013, playing a role in connection and support. At the same time, the first horizontal plate 5012 is horizontally arranged, facilitating the subsequent arrangement and placement of automotive parts.

[0067] The second vertical plate 5013: is arranged parallel to the first vertical plate 5011, jointly forming the two side walls of the hook 501; it can perform lateral limit on automotive parts.

[0068] Furthermore, in the present invention, the first vertical plate 5011 is connected to the second vertical plate 5013 through the first horizontal plate 5012, forming a stable frame structure. The first vertical plate 5011 and the second vertical plate 5013 are parallel to each other, and the first horizontal plate 5012 is perpendicular to both the first vertical plate 5011 and the second vertical plate 5013, ensuring the stability and symmetry of the structure.

[0069] The first vertical plate 5011, the first horizontal plate 5012, and the second vertical plate 5013 jointly enclose a groove for placing parts to be painted, called the part placement groove. The shape and size of this groove can be designed according to the specific shape and size of the parts to be painted to ensure that the parts can be stably placed therein. Generally, the part placement groove is a rectangular groove, which is convenient for cooperating with the pressing plate 503 to press and fix automotive parts.

[0070] The part placement groove provides a stable placement space for the parts to be painted, ensuring that the parts will not shake or shift during the electrophoretic coating process.

[0071] Through the mutual connection of the first vertical plate 5011, the first horizontal plate 5012, and the second vertical plate 5013, the hook 501 body forms a solid frame structure, which can bear the weight of the parts and the external forces that may be generated during the coating process. This hook 501 structure can be adjusted according to the shapes and sizes of different parts. By changing the size and shape of the part placement groove, it can be applied to various types of automotive parts.

[0072] The design of the part placement groove ensures the stable placement of the parts during the coating process, reduces the possibility of shaking, and thus improves the coating quality.

[0073] The hook 501 body is composed of a simple plate-like structure, which is easy to manufacture and maintain, reducing the production cost.

[0075] Further, in the present invention, the hook 501 further includes a second transverse plate 5014. The first transverse plate 5012 and the second transverse plate 5014 are distributed at both ends of the first longitudinal plate 5011. The hook 501 is connected to the cross plate 1 through the second transverse plate 5014. The main function of the second transverse plate 5014 is to connect the hook 501 to the cross plate 1.

[0076] It is located at the other end of the first longitudinal plate 5011 of the hook 501 body and, together with the first transverse plate 5012, is distributed at both ends of the first longitudinal plate 5011. Through the arrangement of the second transverse plate 5014, it facilitates the installation and fixation of the second transverse plate 5014 on the cross plate 1.

[0077] The second transverse plate 5014 is connected to the cross plate 1 by a certain fixing method (such as bolts, welding, etc.) to ensure that the position of the hook 501 on the cross plate 1 is fixed and stable.

[0078] Further, in the present invention, the pressing plate 503 is connected to the hook 501 through a sliding guiding mechanism. The sliding guiding mechanism includes a guiding longitudinal groove 506 provided on the hook 501 and a guiding block 507 provided at the end of the pressing plate 503. The pressing plate 503 is inserted into the guiding longitudinal groove 506 of the hook 501 through the guiding block 507. Through the mutual cooperation of the guiding longitudinal groove 506 and the guiding block 507 in the present invention, the linearity of the movement of the pressing plate 503 can be ensured. The mutual cooperation of the hook 501 and the pressing plate 503 can ensure the stability of the position of the pressing plate 503 during subsequent use and reduce the shaking of the pressing plate 503 during subsequent pressing and fixing.

[0079] Further, in the present invention, the pressing mechanism is connected to the hook 501 through a fixing plate 505. The pressing driving member passes through the fixing plate 505 and is connected to the pressing plate 503. The setting of the fixing plate 505 plays a good bridging role and facilitates the installation and fixation of the pressing mechanism on the hook 501.

[0080] In the present invention, the fixing plate can be connected to the hook in a detachable connection manner, and the two can be connected by screws or bolts. In the present invention, the fixing plate can be designed as an L-shaped plate structure, and a through-hole is provided on the fixing plate. The driving piston of the pressing driving member passes through the above through-hole and is connected to the pressing plate.

[0081] Furthermore, in the present invention, the pressing plate 503 is connected with a pressing and buffering mechanism. The pressing and buffering mechanism includes a clamping plate 6, and the clamping plate 6 is connected with the pressing plate 503 through a supporting and buffering mechanism; the supporting and buffering mechanism includes at least one buffering component, and each buffering component includes a connecting screw rod 7; the clamping plate 6 is connected to the pressing plate 503 through the connecting screw rod 7; an elastic member is sleeved on the connecting screw rod 7; one end of the elastic member is in contact with the pressing plate 503, and the other end is in contact with the pressing plate 503; with the arrangement of the supporting and buffering mechanism of the present invention, during use, the position of the clamping plate 6 has a certain floating ability, avoiding rigid extrusion of the parts to be painted by the clamping plate 6; reducing the extrusion loss of the parts to be painted.

[0082] In the present invention, the clamping plate 6 is located below the pressing plate 503 and is in direct contact with the parts to be painted; the parts are clamped and fixed by applying pressure through the clamping plate 6.

[0083] The supporting and buffering mechanism includes buffering components, and each buffering component includes a connecting screw rod 7 and an elastic member (such as a spring).

[0084] One end of the connecting screw rod 7 is connected to the pressing plate 503, and the other end is connected to the clamping plate 6; the elastic member (such as a spring) is sleeved on the connecting screw rod 7, with one end in contact with the pressing plate 503 and the other end in contact with the clamping plate 6; when the pressing plate 503 moves downward to apply pressure to the parts, the elastic member (such as a spring) is compressed, playing a buffering role and avoiding damage to the parts caused by excessive pressure.

[0085] Through the elastic characteristics of the elastic member, the pressure applied to the parts can be adjusted to ensure that the clamping force is appropriate.

[0086] The elastic member (such as a spring) plays a buffering role between the pressing plate 503 and the clamping plate 6, avoiding damage to the parts due to excessive pressure when the pressing plate 503 directly contacts the parts.

[0087] Through the elastic characteristics of the elastic member, the pressure applied to the parts can be adjusted to ensure that the clamping force is appropriate, neither causing the parts to loosen due to insufficient pressure nor causing damage to the parts due to excessive pressure.

[0088] The buffering effect of the elastic member makes the clamping process smoother, reducing the shaking of the parts caused by sudden application of pressure.

[0089] The buffering effect of the elastic member effectively avoids damage to the parts caused by excessive pressure, improving the painting quality of the parts.

[0090] Through the elastic characteristics of the elastic member, the pressure applied to the parts can be adjusted to ensure that the clamping force is appropriate, improving the versatility and adaptability of the fixture.

[0091] The buffering effect of the elastic member makes the clamping process smoother, reduces the shaking of components caused by sudden application of pressure, and improves the stability of the painting process.

[0092] The structure of the elastic member (such as a spring) is simple, easy to inspect and replace, reducing the maintenance cost.

[0093] The pressing and buffering mechanism is applicable to the electrophoretic painting process of automotive components, especially in occasions where precise clamping and protection of components are required; through the buffering effect of the elastic member, the fixture can better adapt to components of different shapes and sizes, ensuring the stability of the components during the painting process, thereby improving the painting quality and production efficiency; through the design of the pressing and buffering mechanism, the connection between the pressing plate 503 and the clamping plate 6 is more flexible and safe; the buffering effect of the elastic member not only protects the components from damage, but also improves the versatility and adaptability of the fixture.

[0094] Further, in the present invention, a pressing groove is provided at one end of the clamping plate 6 away from the pressing plate 503; the pressing groove is an arc-shaped groove; the pressing groove is located at one end of the clamping plate 6 away from the pressing plate 503, that is, the part where the clamping plate 6 is in direct contact with the component to be painted.

[0095] The design of the pressing groove enables the clamping plate 6 to better fit the surface of the component, ensuring uniform distribution of the clamping force and improving the stability and reliability of clamping.

[0096] The pressing groove is an arc-shaped groove; the arc-shaped groove can better fit the surface of the component, especially those with curved surfaces, ensuring uniform distribution of the clamping force.

[0097] The arc-shaped groove can reduce the hard contact between the clamping plate 6 and the component, avoiding scratching or damage to the component caused by sharp edges; the design of the arc-shaped groove enables the clamping plate 6 to adapt to various components of different shapes, improving the versatility of the fixture.

[0098] Further, in the present invention, two hanging mechanisms 5 are provided on each cross plate 1, and the two hanging mechanisms 5 are distributed relatively on the cross plate 1; the hook 501 in each hanging mechanism 5 is connected to the cross plate 1 through the second transverse plate 5014; two hanging mechanisms 5 are provided on each cross plate 1; this design can improve the utilization rate of the cross plate 1 and ensure the efficiency of the painting process at the same time.

[0099] The two hanging mechanisms 5 are distributed relatively on the cross plate 1; this layout can ensure the balance of the cross plate 1 and reduce the shaking or instability caused by asymmetric distribution.

[0100] The hook 501 in each hanging mechanism 5 is connected to the cross plate 1 through the second transverse plate 5014.

[0101] The second transverse plate 5014 fixes the hook 501 on the transverse plate 1, ensuring the stable position of the hook 501 on the transverse plate 1; through the connection of the second transverse plate 5014, the fixing of the hook 501 on the transverse plate 1 is more firm, enhancing the stability of the entire hanging mechanism 5.

[0102] The two hanging mechanisms 5 are distributed relatively, which can ensure the balance of the transverse plate 1 during the painting process and reduce the shaking.

[0103] Two hanging mechanisms 5 are arranged on each transverse plate 1, which can improve the utilization rate of the transverse plate 1 and ensure the efficiency of the painting process at the same time.

[0104] Two hanging mechanisms 5 are arranged on each transverse plate 1, which can hang two parts simultaneously, improving the painting efficiency.
