Description

Technical Field

[0001] This utility model relates to the field of chassis spraying technology, and in particular to a chassis cover spraying fixture. Background Technology

[0002] During the manufacturing process of the chassis cover, surface painting is required. Currently, the chassis cover mainly consists of a cover body, with left and right side walls on both sides. The top and bottom of the cover body have upper and lower folded edges, respectively. Several ventilation holes are provided on the left and right side walls, and cover mounting lugs are provided on the vertical sides of the left and right side walls. After machining, the chassis cover needs to be painted on its outer surface. However, painting can only be done on the outer surface, not the inner surface. Furthermore, due to the presence of ventilation holes, paint can seep into the interior during painting, potentially causing the inner surfaces to be painted around the ventilation holes as well, thus affecting the painting quality of the chassis cover. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a chassis cover spraying fixture, which can quickly fix the chassis cover and protect the interior, and facilitate hanging for painting.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a chassis cover spraying fixture, wherein the chassis cover includes a cover body, and a left side wall and a right side wall are provided on the left and right sides of the cover body. An upper folded edge and a lower folded edge are respectively provided at the upper and lower ends of the cover body. A plurality of ventilation holes are provided on the left and right side walls. Cover hanging ears are provided on the vertical sides of the left and right side walls. The spraying fixture includes a middle support, and an upper base plate and a lower base plate are provided on the middle support. The upper folded edge and the lower folded edge are respectively fastened to the upper base plate and the lower base plate. Ventilation hole sealing plates for sealing ventilation holes are snapped on the inner sides of the left and right side walls. A left hanging plate and a right hanging plate are also provided on the left and right sides of the upper and lower base plates. The left hanging plate and the right hanging plate are respectively hooked and cooperated with the cover hanging ears on the left and right side walls. Hanging holes are provided at the upper ends of the left hanging plate and the right hanging plate.

[0005] As a preferred embodiment, the left and right hanging plates have the same structure and are symmetrically arranged. The left hanging plate is provided with a hanging plate lug, and the hanging plate lug and / or the cover lug are provided with a hanging groove. The hanging plate lug hooks and engages with the corresponding cover lug.

[0006] As a preferred embodiment, a bolt-connecting post is provided on the inner side of the housing body. The vent sealing plate includes a sealing plate portion and a connecting plate portion connected in an L-shape. The sealing plate portion fits against the left or right side wall to seal the vent. The connecting plate portion is provided with a sleeve hole that fits onto the bolt-connecting post. The connecting plate portion fits against the inner side of the housing body.

[0007] As a preferred embodiment, the upper base plate and the lower base plate are symmetrically covered by the chassis cover on their front and rear sides, and the front and rear ends of the left and right mounting plates are provided with mounting lugs.

[0008] As a preferred embodiment, positioning grooves are provided on the left and right sides of both the upper and lower base plates, and the left and right hanging plates are respectively constrained within the positioning grooves.

[0009] As a preferred embodiment, the vent sealing plate has an L-shaped bend on its sealing plate portion, and the edges of the left and right side walls are also provided with connecting strips. The bend and the connecting strips are in contact and cooperate with each other. The connecting strips and the cover body cooperate to constrain the front and rear position of the vent sealing plate.

[0010] As a preferred embodiment, the intermediate support further includes a vertical plate connecting the upper base plate and the lower base plate. The vertical plate is provided with vertical reinforcing ribs, which are welded to the upper base plate and the lower base plate and fixed by insertion.

[0011] After adopting the above technical solution, the effect of this utility model is as follows: The spraying fixture includes a middle support, on which a parallel upper base plate and a lower base plate are provided. The upper folded edge and the lower folded edge are respectively fastened to the upper base plate and the lower base plate. Ventilation hole sealing plates for sealing ventilation holes are fastened to the inner sides of the left side wall and the right side wall. A left hanging plate and a right hanging plate are also provided on the left and right sides of the upper base plate and the lower base plate. The left hanging plate and the right hanging plate are respectively connected to the covers on the left side wall and the right side wall. The mounting brackets are designed for hook-and-loop engagement. The upper ends of the left and right mounting plates have hanging holes. Therefore, during assembly, the vent sealing plates are first attached to the left and right side walls to block the ventilation holes. Then, the upper and lower folded edges are fastened onto the upper and lower base plates. At this point, the chassis cover is supported on the upper and lower base plates. Next, the left and right mounting plates are installed from both sides to engage with the mounting brackets. Finally, the hanging holes are hooked onto the hooks of the paint spraying conveyor line to paint the outer surface of the chassis cover. This painting fixture in this embodiment can protect the inside of the chassis cover, is easy to assemble, and prevents the inner surfaces from being painted.

[0012] Furthermore, since the left and right hanging plates have the same structure and are symmetrically arranged, the left hanging plate is provided with a hanging plate lug, and the hanging plate lug and / or the cover lug are provided with a hanging groove. The hanging plate lug hooks and engages with the corresponding cover lug. Therefore, during assembly, the hanging plate lug on the left hanging plate is first misaligned with the cover lug, and then it is slid horizontally upward to complete the hanging plate lug being locked in the hanging groove, making hooking convenient.

[0013] Furthermore, since the inner side of the housing body is provided with bolt connecting posts, the vent sealing plate includes a sealing plate part and a connecting plate part connected in an L-shape. The sealing plate part fits against the left or right side wall to seal the ventilation hole. The connecting plate part is provided with a sleeve hole that fits onto the bolt connecting posts. The connecting plate part fits against the inner side of the housing body. Therefore, the vent sealing plate can fit better to seal the ventilation hole. Then, the bolt connecting posts are fitted into the sleeve holes, thereby completing the sealing of the vent sealing plate.

[0014] Furthermore, since the upper and lower base plates are symmetrically fitted with the chassis cover on their front and rear sides, and the front and rear ends of the left and right hanging plates are provided with hanging lugs, two chassis covers can be symmetrically installed on the upper and lower base plates, thus improving the spraying efficiency.

[0015] Furthermore, since the upper base plate and the lower base plate are provided with positioning grooves on the left and right sides, and the left hanging plate and the right hanging plate are respectively constrained in the positioning grooves, the left hanging plate and the right hanging plate can be easily positioned, thereby ensuring better hook-and-loop engagement between the hanging plate lugs and the cover lugs.

[0016] Furthermore, since the sealing plate of the vent sealing plate is provided with an L-shaped bend, and the edges of the left and right sides are also provided with connecting strips, the bend and the connecting strips are in contact and cooperate with each other. The connecting strips and the cover body work together to constrain the front and rear position of the vent sealing plate. Therefore, the vent sealing plate is better squeezed and stuck between the connecting strips and the cover body, thus achieving a better fit and mounting. Attached Figure Description
