Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a pressure sandblasting machine. Background Technique

[0002] A pressure sandblasting machine is a tool that uses a compressed air stream to spray quartz sand on the surface of stainless steel parts for surface cleaning or finishing processing. When aluminum bottles are being produced and processed, a sandblasting machine is usually required to clean the metal burrs on the surface, so that impurities, dirt, and oxide layers on the surface of the aluminum bottles are removed. At the same time, the surface of the medium is roughened to improve the surface hardness of the base material. The pressure sandblasting machine is generally set as a manual small turntable. The operator needs to control the spray gun while rotating the small turntable to control the aluminum bottle. The manual control of the turntable results in uneven sandblasting, and it is easy to cause scratches and deformation on the surface of the workpiece. For this reason, we propose a pressure sandblasting machine. Content of the Utility Model

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1-6 , the present invention provides a technical solution:

[0026] Embodiment 1

[0027] A pressure sandblasting machine, comprising: a sandblasting box 001;

[0028] It further includes:

[0029] A fixed table 002, which is arranged inside the sandblasting box 001 and is used to support and fix the main parts;

[0030] A transmission assembly 003, which is arranged inside the fixed table 002 and is used to drive multiple aluminum bottles to move together.

[0031] Among them, the staff can first put the aluminum bottles with external thread inserts to be processed and cleaned into the placement table 004 inside the sandblasting box 001 one by one. Subsequently, the staff picks up the spray gun to clean the impurities, burr dirt and oxide layer on the surface of the aluminum bottle. At the same time, the transmission assembly 003 drives several aluminum bottles at a constant speed, and several aluminum bottles rotate simultaneously. Then, the staff can evenly sandblast the aluminum bottles.

[0032] A gas box 110 is arranged at the top of the sandblasting box 001, two operation ports 120 are arranged at the front end of the sandblasting box 001, a filter screen 130 is fixedly connected inside the sandblasting box 001, and a sand box 140 is connected to the bottom of the sandblasting box 001.

[0033] Among them, the staff adjusts the sandblasting parameters, wears personal protective equipment, and then inserts both hands into the two operation ports 120 respectively. Subsequently, the staff picks up the spray gun below the gas box 110, aims the spray gun at the aluminum bottle with an external thread insert, cleans and modifies the surface of the aluminum bottle, and the coarse sand ejected will enter the sand box through the filter screen 130, so as to facilitate the recycling of the coarse sand.

[0034] The transmission assembly 003 includes a toothed ring 301, transmission gears 302 and a servo motor 303. Four transmission gears 302 are meshed and connected to the outer wall of the toothed ring 301. The toothed ring 301 is rotatably connected to the fixed table 002. The four transmission gears 302 are distributed in a circular array about the central axis of the toothed ring 301. A servo motor 303 is installed at the rear end of one of the transmission toothed rings 301.

[0035] Among them, the servo motor 303 drives one of the transmission gears 302 to rotate. The transmission gear 302 drives the toothed ring 301 to rotate inside the fixed table 002. While the toothed ring 301 is rotating, it drives the other three transmission gears 302 meshed and connected to it to rotate synchronously. Thus, the surface of the aluminum bottle can be exposed at a constant speed, which is convenient for the staff to sandblast the aluminum bottle without dead angles, sandblast the aluminum bottle evenly, avoid over-sanding a certain position of the aluminum bottle, and cause damage to the surface of the aluminum bottle. Moreover, it is set to drive four aluminum bottles at the same time, and the staff can sandblast the four aluminum bottles at the same time, improving the working efficiency of the device.

[0036] A protective shell 210 is fixedly connected to the outer wall of the fixed table 002. The ends of the four transmission gears 302 are fixedly connected with rotating rods 220. The rotating rods 220 are rotatably connected to the protective shell 210. The rotating rods 220 penetrate through the protective shell 210, and a clamping box 230 is fixedly connected to the bottom end of the rotating rods 220.

[0037] An activity groove 231 is opened inside the clamping box 230. Two clamping plates 232 are slidably connected to the inner wall of the activity groove 231. The two ends of the rear sides of the two clamping plates 232 are fixedly connected with telescopic springs 233. The clamping plates 232 are movably connected to each other through the telescopic springs 233.

[0038] Among them, the staff puts the four aluminum bottles on the placing table 004 one by one, and overcomes the elastic force of the telescopic springs 233 at the rear ends of the two clamping plates 232 to spread apart the two clamping plates 232, so that the two clamping plates 232 clamp the bottom end of the aluminum bottle, thereby grasping the bottom end of the aluminum bottle and fixing the aluminum bottle.

[0039] A fixing rod 234 is connected between the two clamping plates 232. The fixing rod 234 is slidably connected to the clamping plates 232. The inner walls of the two clamping plates 232 are set to be arc-shaped.

[0040] Among them, the setting of the fixing rod 234 can limit the positions of the two clamping plates 232 and avoid the situation that the clamping plates 232 loosen and the aluminum bottle falls off.

[0041] Four placing tables 004 are arranged above the filter screen 130. The four placing tables 004 are distributed in a circular array about the central axis of the fixed table 002. The positions of the placing tables 004 correspond to the positions of the clamping boxes 230 one by one.

[0042] Both ends of the four placement platforms 004 are fixedly connected with sliding rings 410, and the inner walls of the sliding rings 410 are movably connected with a plurality of balls 420 at equal intervals.

[0043] Among them, the placement platform 004 can support the aluminum bottle to ensure the stable rotation of the aluminum bottle. At the same time, the arrangement of the balls 420 reduces the contact area between the aluminum bottle and the placement platform 004, thereby reducing the friction generated when the aluminum bottle rotates, making the rotation of the aluminum bottle smoother.

[0044] Embodiment 2

[0045] In this second embodiment, other structures remain unchanged. Different from the first embodiment, a transmission can be installed at the connection between the transmission gear 302 and the servo motor 303. By adjusting the transmission, the rotation speed of the transmission gear 302 can be adjusted, and thus, according to the processing requirements, the rotation speed of the aluminum bottle can be adjusted to improve the sandblasting efficiency and effect.
