Description

Technical Field

[0001] This utility model relates to the field of coating, sanding, and roughening equipment, and in particular to a sanding and roughening chassis device. Background Technology

[0002] In shipyard painting, roughening refers to the process of using specialized tools or equipment to treat the pre-treated ship surface coating, making the originally smooth surface rough and forming a certain micro-texture and roughness. Shipyard painting operations require roughening between each coat of paint, that is, to strengthen the adhesion between the two coats of paint, the previous coat of paint is sanded and roughened.

[0003] Since the roughening process involves the top layer of paint, the pressure applied needs to be carefully controlled. Currently, the process usually involves manual sanding with an angle grinder. However, the traditional manual roughening method is inefficient and produces inconsistent quality, often requiring multiple reworks to meet the standards, which seriously affects the production schedule. The construction window is relatively short, mainly because if the process cannot be completed quickly before the optimal humidity for painting, it will severely affect the quality of the previous painted surface.

[0004] The existing automated sanding equipment uses a roughening chassis that is required to completely sand away the paint on the base surface. This cannot be applied to the technical problem to be solved in this patent, which is to roughen the paint surface with a certain hardness. Therefore, how to develop a roughening chassis that can balance roughening strength and usage efficiency has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a grinding and roughening chassis device. Under the cooperation of torsion spring and hinge shaft, the grinding end of the roughening mechanism flexibly adheres to the surface to be worked on. Then, as the grinding machine body drives the chassis device to rotate, the chassis device can flexibly roughen the surface to be worked on, so that the roughening chassis can effectively balance roughening force and usage efficiency.

[0006] This utility model is achieved through the following technical solution:

[0007] A grinding and roughening chassis device includes a support plate and multiple roughening mechanisms. The upper surface of the support plate is coaxially connected to the drive end of the grinding machine body. The grinding machine body drives the support plate to rotate. The roughening mechanisms are arranged circumferentially on the lower surface of the support plate and are elastically fixed to the lower surface of the support plate. When grinding is performed, the support plate presses down on the roughening mechanisms, and the grinding end of the roughening mechanism flexibly adheres to the surface to be worked.

[0008] According to the above technical solution, preferably, the texturing mechanism includes a support component, a base, a torsion spring, and a texturing block.

Under the combined action of the torsion spring and the hinge shaft, the grinding end of the roughening mechanism flexibly adheres to the surface to be worked on. Then, as the grinding machine body drives the chassis device to rotate, the chassis device flexibly roughens the surface to be worked on, so that the roughening chassis can effectively balance roughening force and usage efficiency.

[0012] As can be seen, in the above technical solution, the staff can quickly adjust the angle between the base and the fixed plate by turning the adjusting screw.

[0013] According to the above technical solution, preferably, the fixing plate is detachably and fixedly connected to the L-shaped support plate by multiple sets of locking bolts.

[0014] According to the above technical solution, preferably, the multiple sets of texturing mechanisms are arranged in an umbrella-shaped radial structure. The support components include an L-shaped support rod and a fork-shaped pressure plate. The L-shaped support rod is fixedly connected to the lower surface of the support plate. The end of the fork-shaped pressure plate is hinged to the end of the L-shaped support rod through a hinge shaft. A torsion spring is sleeved on the hinge shaft. The two ends of the torsion spring abut against the L-shaped support rod and the fork-shaped pressure plate, respectively. The base is hinged to the fork-shaped pressure plate through a hinge shaft. The torsion spring is sleeved on the hinge shaft. The texturing block is fixedly connected to the base. The torsion spring drives the base and the texturing block to flexibly adhere to the surface to be constructed.

[0015] According to the above technical solution, preferably, the support assembly includes a fixed seat and an elastic pressure plate unit. The fixed seat is fixedly connected to the lower surface of the support plate, and the elastic pressure plate unit is hinged to the fixed seat and the base respectively through a hinge shaft. A torsion spring is sleeved on the hinge shaft.

[0016] According to the above technical solution, preferably, the elastic pressure plate unit includes two sets of pressure plates, which are fixedly connected to both ends of the hinge shaft, and the pressure plates are symmetrically arranged on both sides of the fixed seat.

[0017] According to the above technical solution, preferably, the elastic pressure plate unit further includes a limiting rod, which is fixedly connected to the pressure plate and abuts against the fixed seat.

[0018] According to the above technical solution, preferably, a distance sensor is provided on the lower surface of the support plate, and the distance sensor is used to sense the distance between the lower surface of the support plate and the surface to be constructed.

[0019] The beneficial effects of this utility model are as follows: When the worker places the grinding equipment on the surface to be worked on, the grinding machine body presses down the chassis device, and the support plate presses down the roughening mechanism. Under the combined action of the torsion spring and the hinge shaft, the grinding end of the roughening mechanism flexibly adheres to the surface to be worked on. Then, as the grinding machine body drives the chassis device to rotate, the chassis device flexibly roughens the surface to be worked on, so that the roughening chassis can effectively balance roughening force and usage efficiency.
