Description

Technical Field

[0001] This utility model relates to the field of polishing devices, and in particular to a surface polishing device for heat exchanger housings. Background Technology

[0002] The main function of a polishing device is to remove surface damage layers, achieving a fine polishing effect and making the surface smoother and shinier. The polishing device uses an electric motor to drive a polishing disc or polishing needle to rotate at high speed, working in conjunction with the polishing compound to remove surface stains, oxide layers, and shallow scratches, thereby achieving the polishing effect.

[0003] After the plastic shell of the heat exchanger is produced, it needs to be polished. The existing polishing methods are mostly done by workers holding the equipment by hand. This polishing method has certain limitations. When multiple surfaces of the plastic part need to be polished, workers need to hold the shell and polish multiple surfaces one by one, which is inefficient. To solve the above problems, a surface polishing device for heat exchanger shells is needed. Utility Model Content

[0004] The purpose of this invention is to provide a surface polishing device for heat exchanger housings to solve the problems mentioned in the background art.

[0009] Preferably, the upper surface of the mounting plate is rotatably connected to a first rotating shaft and a second rotating shaft.

The surface of the second rotating shaft is fixedly connected to a second pin gear and a second polishing disc, and the second pin gear is in contact with a cam disc.

[0010] Preferably, a sliding plate is fixedly connected to the upper surface of the base, a support plate is fixedly connected to the upper surface of the sliding plate, and a friction plate is fixedly connected to one side of the support plate.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

By setting a multi-face polishing mechanism, multiple surfaces can be polished simultaneously, thereby improving polishing efficiency.

[0023] Preferably, the multi-faceted polishing mechanism includes a sleeve 15 fixedly connected to the lower surface of the C-shaped plate 25, an adjusting shaft 16 rotatably connected to the inner wall of the sleeve 15, and a square plate 17 fixedly connected to the surface of the adjusting shaft 16.

[0024] By setting the sleeve 15 and installing the support adjustment shaft 16, the angle position of the square plate 17 can be adjusted, thereby affecting the extension length of the top rod 18.

[0025] Preferably, the multi-face polishing mechanism further includes a push rod 18 slidably connected to the inner wall of the sleeve 15.

One end of the spring 20 is fixedly connected to the inner wall of the sleeve 15, and the other end of the spring 20 is fixedly connected to the surface of the push rod 18.

[0026] By setting the friction sleeve 19, the friction force of the plastic part sleeved on the surface of the sleeve 15 is increased, and the stability of the plastic part is maintained during polishing. By setting the spring 20, the friction sleeve 19 is driven to reset.

[0027] Preferably, a mounting plate 6 and a motor 7 are fixedly connected to the upper surface of the base 1. The output end of the motor 7 passes through the upper surface of the mounting plate 6 and is fixedly connected to a convex shaft disk 8. A third polishing disk 24 is fixedly connected to the upper surface of the convex shaft disk 8.

[0028] By setting the mounting plate 6, the first rotating shaft 10 and the second rotating shaft 9 are supported. By setting the motor 7, the motor 7 is started, which drives the cam disc 8 and the third polishing disc 24 to rotate. By setting the third polishing disc 24, the polishing operation is performed.

The friction sleeve 19 is reset under the action of the spring 20, realizing the effect of material detachment from the sleeve 15.

[0033] The working principle of this utility model is as follows: A surface polishing device for a heat exchanger shell, before polishing, a plastic shell is fitted onto a sleeve 15. Rotating the adjusting shaft 16 rotates the square plate 17, causing the push rod 18 to push the friction sleeve 19 into contact with the surface of the shell, thus positioning the plastic shell. Then, the motor 7 and a pair of electric drive shafts 2 are started. The first synchronous pulley 3 and the second synchronous pulley 4 drive the synchronous belt 5 to rotate.

The first polishing disc 12, the second polishing disc 13 and the third polishing disc 24 rotate to perform friction polishing on the plastic shell. After the plastic shell is polished, the adjusting shaft 16 contacts the surface of the friction plate 22, driving the square plate 17 to rotate, so that the top rod 18 drives the friction sleeve 19 to slide back to its original position under the action of the spring 20, releasing the friction contact state with the plastic shell. At this time, the plastic shell separates from the surface of the sleeve 15 and slides off the slide plate 23. With the above structure, multiple surfaces can be polished, improving the polishing efficiency.
