[0036] The present invention is described in detail below by way of embodiments with reference to the accompanying drawings.

[0037] It should be noted that certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that technicians may use different nouns to refer to the same component. This specification and claims do not use the difference in nouns as a way to distinguish components, but use the difference in the functions of the components as the criterion for distinction. As mentioned throughout the specification and claims, "including" or "comprising" is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred embodiment of the implementation of the utility model, but the description is based on the general principles of the specification and is not used to limit the scope of the utility model. The scope of protection of the utility model shall be determined by the definition of the attached claims. Example

[0038] As attached Figure 1 As shown, this embodiment describes a gear box housing cleaning system, including a conveying turntable, a housing fixture 1, and a cleaning device.

[0039] The conveying turntable includes a turntable body 201 , a slide rail 206 , a driving sprocket 204 , a driven sprocket 205 , a bent plate chain 203 , and a motor 202 .

[0040] The slide rail 206 is fixedly mounted on the side of the turntable body 201 . The slide rail 206 is in the shape of a rounded rectangle as a whole and is preferably disposed close to the edge of the turntable body 201 .

[0041] The driving sprocket 204 and the driven sprocket 205 are arranged on the horizontal central axis of the turntable body 201 and are connected and fixed by the bent plate chain 203 .

[0042] The bent plate chain 203 preferably adopts a single-sided bent plate chain.

[0043] The motor 202 is installed on the other side of the turntable body 201 , and its output shaft is connected and fixed to the driving sprocket 204 for outputting power and driving the driving sprocket 204 to rotate.

[0044] The housing fixture 1 is plate-shaped as a whole, and a positioning point and a clamping mechanism are arranged on its surface. The positioning point is used to position the gearbox housing during loading and unloading, and the clamping mechanism is used to clamp and fix the gearbox housing on the surface of the housing fixture 1.

[0045] The clamping mechanism can adopt commonly used mechanical fixing structures such as bolt fixing, pressure plate fixing, etc., which will not be described in detail here.

[0046] A slider matched with the slide rail 206 is fixedly arranged on the back of the housing fixture 1, and the bottom of the housing fixture 1 is fixedly arranged on the single-side bent plate of the bent plate chain 203 by bolts. The slider can be welded and fixed on the back of the housing fixture 1.

[0047] The motor 202 is turned on to drive the driving sprocket 204 to rotate, and the bent plate chain 203 rotates synchronously. Under the driving force of the bent plate chain 203, the housing clamp 1 moves synchronously with the bent plate chain 203 through the cooperation of the slider and the slide rail 206. Since the two end surfaces of the slide rail 206 are set in semicircular shape, the slide rail 206 has a smooth running track, and the housing clamp 1 can move along the slide rail 206 in a synchronous and smooth cycle with the bent plate chain 203.

[0048] The cleaning device is set as an ultrasonic cleaning box 301. The ultrasonic cleaning box 301 is set below the turntable body 201, and the relative distance between the ultrasonic cleaning box 301 and the turntable body 201 is set according to the actual needs of the production operation, as well as the length and depth of the ultrasonic cleaning box 301. The setting should be such that the gear box housing running below the turntable body 201 can be completely immersed in the cleaning solution. Example

[0049] As attached Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, based on Example 1, a gear box housing cleaning system recorded in this example further includes a loading and unloading mechanism.

[0050] The loading and unloading mechanism preferably adopts a robot 401.

[0051] The manipulator 401 is set at the manipulator position. Through program debugging, the manipulator 401 is used to pick up the gear box housing before cleaning, and install the gear box housing on the surface of the housing fixture 1 according to the set motion trajectory to complete the gear box housing loading operation.

[0052] At the same time, the manipulator 401 is also used to remove the cleaned gear box housing from the housing fixture 1 to complete the gear box housing unloading operation.

[0053] The positioning points on the surface of the housing fixture 1 are used for auxiliary positioning of the robot.

[0054] In order to enable the robot 401 to complete the loading and unloading operations of the shell more smoothly, the clamping mechanism of the shell clamp 1 is structurally changed in this embodiment.

[0055] In this embodiment, there are multiple clamping mechanisms, and the specific number is determined according to actual production operation requirements and factors such as the weight of the shell.

[0056] The clamping mechanism includes a cavity 501, a spring 502 disposed inside the cavity, and a steel ball 503 fixed to the front end of the spring.

[0057] An opening is provided at the front end of the cavity 501. By changing the length of the cavity 501, the spring 502 inside is in a compressed state, and at least two-thirds of the diameter length of the steel ball 503 is further arranged to be located outside the cavity 501, and the gap between the steel ball 503 and the surface of the shell fixture 1 is ≧ the edge thickness of the gear box shell.

[0058] During loading:

[0059] The manipulator 401 takes the gear box housing and places the gear box housing on the surface of the housing fixture 1 along the running trajectory set by the program;

[0060] The manipulator 401 provides a set thrust, and the edge of the gearbox housing moves along the surface of the steel ball 503 toward the surface of the housing fixture 1. Due to the spherical structure of the steel ball 503, the gearbox housing can smoothly press the steel ball 503 toward the inside of the cavity 501 under the action of the thrust;

[0061] After the gearbox housing is attached to the surface of the housing fixture 1 , the steel ball 503 is quickly reset under the pressure of the spring 502 , and the edge of the gearbox housing is fixed in the gap between the steel ball 503 and the surface of the housing fixture 1 .

[0062] The unloading process is the reverse operation process of the above process. Its operating principle is the same as that of the loading process, so it will not be repeated here. Example

[0063] As attached Figure 5 As shown, based on Example 1 or Example 2, a gear box housing cleaning system recorded in this example further includes a water removal and dust removal mechanism.

[0064] The water and dust removal mechanism includes a base 601 and a plurality of steel air pipes 602 arranged on the base.

[0065] The outlet of the steel air pipe 602 is arranged adjacent to the surface of the gearbox housing.

[0066] The steel air pipe 602 is connected to an external air compression device, such as an air compressor, to provide pressurized gas of a set pressure, thereby removing debris such as dust, machining chips, and residual water attached to the surface of the gearbox housing.

[0067] The base 601 is fixed to the upper end surface of the turntable body 201 by welding with a bracket. The welding position of the bracket on the turntable body 201 should be selected at a position that avoids obstruction of the operation of other structures of the system.

[0068] There may be multiple water removal and dust removal mechanisms, and this embodiment does not limit the specific number of the mechanisms. Example

[0069] As attached Figure 6 As shown, based on any one of embodiments 1-3, a gear box housing cleaning system recorded in this embodiment further includes a water cleaning mechanism.

[0070] The water cleaning mechanism includes a circulating filtering water tank 701 .

[0071] The circulating filtering water tank 701 is connected to the ultrasonic cleaning tank 301 through a water pipe, and a valve is provided at the water pipe.

[0072] Filter materials such as sponges and a submersible pump are arranged in the circulating filtration water tank 701, and the submersible pump is fixedly connected to the water pipe.

[0073] Open the valve and start the submersible pump. The water or other solution in the ultrasonic cleaning tank 301 flows into the circulating filtration water tank 701 through the water pipe, and after the water body is filtered by the filter material arranged inside the circulating filtration water tank 701, it is pumped back into the ultrasonic cleaning tank 301.

[0074] A plurality of circulating filtration water tanks 701 may be connected in series or in parallel to form a multi-stage filtration system. This embodiment does not limit the specific number of circulating filtration water tanks 701 .

[0075] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
