Description

Technical Field

[0001] The utility model belongs to the technical field of tools for automobile production, and in particular relates to an engine coating line. Background Art

[0002] The structure of the engine painting line mainly includes: conveyor belt (chain), hook, spray room, and drying room. The function of the engine painting line is mainly to perform protective and decorative painting operations on engine parts such as engine cover, oil pan, cooler, etc.

[0003] On the other hand, the common hooks mentioned above have a relatively simple structure, which mainly includes a hook body and a connecting structure of a conveyor belt (chain), which ultimately ensures that the workpiece to be painted can enter and exit the spraying room and the drying room together with the conveyor belt (chain).

[0004] For example, a Chinese utility model patent with patent announcement number CN219003448U and announcement date 2023.05.12 discloses a special hanger for powder coating of engine oil pan, including a main body, which is a columnar structure, and a hook A is installed on the rear side of the main body. The main body and the hook A together form a connecting structure, and a telescopic rod is inserted into the left side of the outer peripheral surface of the main body. The telescopic rod is provided at two locations, and the two telescopic rods are arranged in a linear array, and a handle is installed on the left side of the telescopic rod.

[0005] The structural principle and advantages of the hanger in this utility model patent are generally as follows: through the inclined setting of the main body and the hook B, the purpose of keeping the opening of the oil pan continuously inclined when limiting the oil pan can be achieved, so that the accumulated water inside can be quickly discharged during flushing.

[0006] However, in actual use, the hanger still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0007] 1. The hook A structure is on the conveyor belt (chain), which is easy to shift left and right, thus reducing the quality of painting and damaging adjacent workpieces;

[0008] 2. The workpiece to be painted lacks height adjustment function on this hanger, so the scope of application is relatively small. If the part to be painted on the workpiece is too low or too high, the problem of inadequate painting is likely to occur.

[0009] Therefore, in summary, there is an urgent need for a new coating line structure in which the hook itself is not easy to slide and shift, and the height of the workpiece to be painted can be adjusted, so as to be used for painting various engine parts. Utility Model Content

[0010] The utility model provides an engine coating line, which can arrange mounting holes, perforated frame units, perforated column units, lifting plate units, limit rod units, and screw-connected hooks on a conveyor belt, so that: 1. the screw-connected hooks are indirectly plugged on the conveyor belt to ensure that the workpieces on the screw-connected hooks will not shift on the conveyor belt; 2. the lifting plate unit can adjust the height of the workpiece to ensure that within a certain range, the parts to be painted can be effectively painted, whether high or low.

[0011] The technical solution adopted by the utility model to solve the above-mentioned problems is: an engine painting line, the structure of which includes a conveyor belt and a screw-connected hook, and also includes a mounting hole arranged on the conveyor belt, an open-hole frame unit arranged on the upper surface of the conveyor belt and engaged with the side of the conveyor belt, an open-hole column unit inserted in the mounting hole and the open-hole frame unit and used for installing the screw-connected hook at the lower end, a lifting plate unit arranged on the upper surface of the open-hole frame unit, and a limit rod unit inserted in the open-hole column unit and used for engaging with the upper surface of the lifting plate unit.

[0012] A further preferred technical solution is that the perforated frame unit includes an intermediate plate arranged on the upper surface of the conveyor belt, two limiting side plates respectively arranged at both ends of the intermediate plate, and a connecting hole arranged on the intermediate plate and used to pass through the perforated column unit.

[0013] A further preferred technical solution is that the perforated frame unit further includes a first anti-slip strip arranged on the lower surface of the middle plate.

[0014] A further preferred technical solution is that the open-hole column unit includes a vertical column inserted into the mounting hole and the connecting hole, a hanging hole arranged on the vertical column and used to insert the limiting rod unit, and a threaded groove arranged on the lower end surface of the vertical column and used to install the threaded hook.

[0015] A further preferred technical solution is that the lifting plate unit includes a vertical stud arranged on the upper surface of the intermediate plate, a transverse plate for supporting the limiting rod unit, an end hole arranged on the transverse plate and used to pass through the vertical stud, and an adjusting nut arranged on the vertical stud and used to support the transverse plate.

[0016] A further preferred technical solution is that the lifting plate unit further includes an anti-drop nut which is arranged on the vertical stud and is used to press down the transverse plate.

[0017] A further preferred technical solution is that the lifting plate unit further comprises an arc-shaped groove which is arranged on the upper surface of the transverse plate and is used for engaging the limiting rod unit.

[0018] A further preferred technical solution is that the lifting plate unit further includes a second anti-slip strip arranged on the arc-shaped groove.

[0019] A further preferred technical solution is that the limiting rod unit includes a transverse rod which is inserted into the hanging hole and is used for engaging above the lifting plate unit.

[0020] A further preferred technical solution is that the limiting rod unit further includes a pull ring arranged at the end of the transverse rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0033] As attached Figure 1-7 As shown, an engine coating line has a structure including a conveyor belt 11 and a screw-connected hook 12, and also includes a mounting hole 1 arranged on the conveyor belt 11, an open-hole frame unit 2 arranged on the upper surface of the conveyor belt 11 and engaged with the side of the conveyor belt 11, an open-hole column unit 3 inserted in the mounting hole 1 and the open-hole frame unit 2 and used for installing the screw-connected hook 12 at the lower end, a lifting plate unit 4 arranged on the upper surface of the open-hole frame unit 2, and a limit rod unit 5 inserted in the open-hole column unit 3 and used for engaging with the upper surface of the lifting plate unit 4.

[0034] In this embodiment, the conveyor belt 11 can be a belt or a steel belt. One end of the screw hook 12 is a stud and the other end is a hook body, and the tip of the hook is upturned to ensure that engine workpieces such as the oil pan are more stably suspended on the hook with the upturned tip.

[0035] In addition, the conveyor belt 11 is wound around the two driving rollers 13, and the driving rollers 13 are located outside the paint spraying room 14. The integral structure composed of the perforated frame unit 2, the perforated column unit 3, the lifting plate unit 4 and the limit rod unit 5 can be hung up and removed when the mounting hole 1 is located outside the paint spraying room 14, thereby ensuring the effectiveness of the entire painting operation.

[0036] Among them, the installation hole 1 only needs to allow the perforated column unit 3 to pass through, and the perforated frame unit 2 is in an inverted U shape, which is stuck on both sides of the conveyor belt 11 to ensure that the perforated column unit 3 is more stable and not easy to shift compared to the installation hole 1.

[0037] Finally, the lifting plate unit 4 indirectly lifts and lowers the workpiece, and the limiting rod unit 5 ensures that the perforated column unit 3 and the workpiece are stably suspended.

[0038] The perforated frame unit 2 includes an intermediate plate 201 arranged on the upper surface of the conveyor belt 11, two limiting side plates 202 respectively arranged at both ends of the intermediate plate 201, and a connecting hole 203 arranged on the intermediate plate 201 and used to pass through the perforated column unit 3.

[0039] In this embodiment, the connection hole 203 is in a square shape, and accordingly, the cross-sectional shape of the perforated column unit 3 is also in a square shape, so as to prevent the workpiece from rotating uncontrollably.

[0040] The perforated frame unit 2 further includes a first anti-slip strip 204 disposed on the lower surface of the middle plate 201 .

[0041] In this embodiment, the perforated frame unit 2 is first buckled on the conveyor belt 11, and then the perforated column unit 3 is inserted upward. During this period, the first anti-slip strip 204 can prevent the entire perforated frame unit 2 from slipping.

[0042] The perforated column unit 3 includes a vertical column 301 inserted into the mounting hole 1 and the connecting hole 203, a hanging hole 302 arranged on the vertical column 301 and used to insert the limiting rod unit 5, and a screw groove 303 arranged on the lower end surface of the vertical column 301 and used to install the screw hook 12.

[0043] In this embodiment, the cross-sectional shape of the vertical column 301 is square, and the hanging hole 302 and the screw groove 303 are both circular, with the former being opened horizontally and the latter being opened vertically.

[0044] The lifting plate unit 4 includes a vertical stud 401 arranged on the upper surface of the middle plate 201, a transverse plate 402 for supporting the limiting rod unit 5, an end hole 403 arranged on the transverse plate 402 and used to pass through the vertical stud 401, and an adjusting nut 404 arranged on the vertical stud 401 and used to support the transverse plate 402.

[0045] In this embodiment, the number of the vertical studs 401 is four, which are arranged in groups of two, corresponding to the two horizontal plates 402 .

[0046] When the adjusting nut 404 is adjusted upward, the workpiece can be indirectly lifted, and vice versa, the position of the workpiece to be painted can be aligned with the nozzle as much as possible.

[0047] The lifting plate unit 4 further includes an anti-drop nut 405 which is arranged on the vertical stud 401 and is used to press down the transverse plate 402 .

[0048] In this embodiment, a single vertical stud 401 is provided with one adjusting nut 404 at the bottom and one anti-drop nut 405 at the top, so as to ensure that the transverse plate 402 is stably installed.

[0049] The lifting plate unit 4 further includes an arc-shaped groove 406 disposed on the upper surface of the transverse plate 402 and used for engaging the limiting rod unit 5 .

[0050] In this embodiment, the main structure of the limiting rod unit 5 is a round rod, and the arc groove 406 can stably engage the limiting rod unit 5 to prevent the limiting rod unit 5 from accidentally sliding out of the hanging hole 302 .

[0051] The lifting plate unit 4 further includes a second anti-slip strip 407 disposed on the arc-shaped groove 406 .

[0052] In this embodiment, the second anti-slip strip 407 made of rubber can further fix the limiting rod unit 5 on the arc groove 406 in an anti-slip manner.

[0053] The limiting rod unit 5 includes a transverse rod 501 which is inserted into the hanging hole 302 and is used for engaging above the lifting plate unit 4 .

[0054] In this embodiment, the transverse rod 501 is a round rod, which is inserted into the hanging hole 302 after the hanging hole 302 exceeds the transverse plate 402 upward.

[0055] The limiting rod unit 5 further includes a pull ring 502 arranged at the end of the transverse rod 501 .

[0056] In this embodiment, after the workpiece is finished painting, the vertical column 301 needs to be lifted appropriately, and then the horizontal rod 501 can be pulled out relatively effortlessly. The above pulling-out action can be performed by holding the pull ring 502 with fingers, ensuring that the plugging and unplugging action of the limit rod unit 5 is more effortless.

[0057] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
