Description

Technical Field

[0001] This utility model relates to the field of automotive painting, and in particular to a universal anti-sticking paint clamp for sliding doors. Background Technology

[0002] Sliding doors need to be installed on the side of the body-in-white using existing fixtures before painting. During painting, the sliding doors rotate around the fixtures. If there is no effective limit, they are prone to contact with the side sheet metal, causing damage to the wet paint film and requiring rework.

[0003] Existing anti-stick coating solutions have significant drawbacks: Poor universality and prone to paint loss: For example, CN215235221U proposes a universal anti-stick paint device for four car doors, which requires the side panel stop edge to be connected by a hole positioning clip. However, light commercial vehicle models have many styles / configurations and the side panel structure varies greatly, making the device difficult to be universal; moreover, the obstruction of the stop edge causes paint loss, and manual repainting is required after disassembly. Weak adsorption and high maintenance: For example, CN223184754U proposes a magnetic door painting limit process lock that relies on magnets to adsorb the inner panel of the sliding door. However, the sliding door is large and heavy, and the magnets are not strong enough to easily detach (which may damage the sheet metal). In addition, the magnets are easy to break and need to be replaced frequently. Cumbersome management and operation: The existing clamps do not utilize the universal structure of the sliding door sill of light passenger vehicles, and different models require different clamps, making on-site management difficult; moreover, the disassembly and assembly are complicated, the weight is large, and the manual operation time is high. Utility Model Content

[0004] The purpose of this invention is to provide a universal anti-sticking paint clamp for sliding doors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a universal anti-sticking paint clamp for sliding doors, comprising a main rod, a connecting plate, a limiting crossbar, a support block, a limiting baffle, a positioning pin, and a limiting block; The connecting plate and the limiting crossbar are respectively located at both ends of the main rod, and the support block is located at the end of the connecting plate, which is used to contact and support the inner panel of the sliding door to maintain the opening angle of the sliding door; The limiting crossbar is used to press against the threshold sheet metal when the inner panel of the sliding door hits the support block, and to provide Z-axis pressure to the clamp to prevent the clamp from springing open. The limiting baffle is inserted through the middle of the main rod and is used to contact the sill sheet metal. When the inner panel of the sliding door hits the support block, it provides Y-axis pressure to the clamp to prevent the clamp from springing open. The positioning pin is connected to the middle of the main rod through a limiting block. The positioning pin is an inclined pin with a preset angle, which is used to insert obliquely into the positioning hole of the sill sheet metal to achieve fixture positioning.

[0006] Preferably, the support block is in the shape of a double cylinder. This double cylinder structure makes the contact between the support block and the inner panel of the sliding door a straight line, so as to disperse the impact force when the inner panel of the sliding door is hit and avoid deformation of the sheet metal of the inner panel of the sliding door.

[0007] Preferably, the angle between the positioning pin and the limiting crossbar is 55 degrees.

[0008] Preferably, the fixture is made entirely of stainless steel and can be reused after cleaning and paint removal.

[0009] Preferably, the connecting plate is Z-shaped, which makes the contact point between the support block and the inner panel of the sliding door located in the interior trim covering area of ​​the final assembly, so as to save the manual repair and rework process of the contact point.

[0010] Preferably, the limiting block is used to limit the clamp in the Z direction to prevent the main rod from directly contacting the sill sheet metal and causing paint damage.

[0011] The technical effects and advantages of this utility model are as follows: By supporting the sliding door through the contact between the support block and the inner panel of the sliding door, the fixed opening angle of the sliding door can be maintained, completely avoiding contact between the sliding door and the side panel sheet metal when the sliding door is closed, and preventing damage to the wet paint film; at the same time, the limiting baffle and the limiting crossbar provide Y-axis and Z-axis pressure respectively, which can resist the impact force when the sliding door rotates, prevent the limit failure caused by the clamp popping open, and further ensure the safe distance between the sliding door and the side panel during the painting process, fundamentally eliminating the problem of paint sticking and rework.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides, for example Figures 1-3The universal anti-sticking paint clamp for sliding doors shown includes a main rod 1, a connecting plate 5, a limiting crossbar 7, a support block 6, a limiting baffle 2, a positioning pin 4, and a limiting block 3; The connecting plate 5 and the limiting crossbar 7 are respectively located at both ends of the main rod 1, and the support block 6 is located at the end of the connecting plate 5, which is used to contact and support the inner panel of the sliding door to maintain the opening angle of the sliding door; The limit bar 7 is used to press against the threshold sheet metal when the inner panel of the sliding door hits the support block 6, and to provide Z-axis pressure to the clamp to prevent the clamp from springing open. The limiting baffle 2 is inserted through the middle of the main rod 1 and is used to contact the sill sheet metal. When the inner panel of the sliding door hits the support block 6, it provides Y-direction pressure to the clamp to prevent the clamp from springing open. The positioning pin 4 is connected to the middle of the main rod 1 through the limiting block 3. The positioning pin 4 is an inclined pin with a preset angle, which is used to insert obliquely into the positioning hole of the sill sheet metal to realize the positioning of the fixture.

[0016] By supporting the sliding door with the contact between the support block 6 and the inner panel of the sliding door, the fixed opening angle of the sliding door can be maintained, completely avoiding contact between the sliding door and the side panel sheet metal when the sliding door is closed, and preventing damage to the wet paint film. At the same time, the limit baffle 2 and the limit crossbar 7 provide Y-axis and Z-axis pressure respectively, which can resist the impact force when the sliding door rotates, prevent the limit failure caused by the clamp popping open, and further ensure the safe distance between the sliding door and the side panel during the painting process, fundamentally eliminating the problem of paint sticking and rework.

[0017] Furthermore, the support block 6 is shaped as a double cylinder. This double cylinder structure ensures that the support block 6 and the inner panel of the sliding door make a straight-line contact, thereby dispersing the impact force when the inner panel of the sliding door is hit and preventing deformation of the inner panel sheet metal.

[0018] Furthermore, the angle between the positioning pin 4 and the limiting crossbar 7 is 55 degrees.

[0019] Furthermore, the entire fixture is made of stainless steel and can be reused after cleaning and paint removal.

[0020] Furthermore, the connecting plate 5 is Z-shaped, which makes the contact point between the support block 6 and the inner panel of the sliding door located in the interior trim covering area of ​​the final assembly, thus eliminating the need for manual repair and rework of the contact point.

[0021] Furthermore, the limiting block 3 is used to limit the fixture in the Z direction to prevent the main rod 1 from directly contacting the sill sheet metal and causing paint damage.

[0022] First, the operator inserts the positioning pin 4 of the fixture into the preset positioning hole of the sill sheet metal at an angle to complete the initial positioning of the fixture. At this time, the limiting block 3 connected to the positioning pin 4 will abut against the sill sheet metal to limit the fixture in the Z direction, preventing the main rod 1 from directly contacting the surface of the sill sheet metal and preventing paint damage to the sheet metal. At the same time, the limiting baffle 2, which is installed in the middle of the main rod 1, will fit against the side of the sill sheet metal to provide a Y-direction support base for subsequent impact resistance.

[0023] During the painting process, due to the support of the support block 6, the sliding door is restricted to a fixed opening angle and cannot move further toward the side panel, thereby avoiding contact between the sliding door and the side panel sheet metal and preventing damage to the wet paint film; at the same time, the Z-shaped structure of the connecting plate 5 ensures that the contact point is located in the part covered by the interior trim of the final assembly, eliminating the need for subsequent touch-up painting.

[0024] When the inner panel of the sliding door strikes the support block 6, it generates an impact force towards the threshold: The impact force will cause the limit bar 7 to press down against the sill sheet metal, providing Z-axis pressure to the clamp, offsetting the Z-axis component of the impact force, and preventing the clamp from springing up. At the same time, the limiting baffle 2 that fits the sill sheet metal will be subjected to lateral compression by the impact force, providing Y-direction pressure to the clamp, offsetting the Y-direction component of the impact force, and preventing the clamp from springing away towards the side. The bidirectional pressure and the Z-axis limiting effect of the limiting block 3 work together to ensure that the fixture remains stable under impact force and avoid limit failure.

[0025] After the painting process is completed, the operator only needs to pull the positioning pin 4 out of the positioning hole of the threshold sheet metal to complete the fixture disassembly; the disassembled fixture is cleaned and depainted, and the treated fixture can be reused for the next batch of sliding door painting operations, realizing recycling.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
