Description

Technical Field

[0001] The invention relates to the technical field of cleaning aluminum chips after milling of a motor housing, and in particular to a pneumatic cleaning device and a cleaning method for aluminum chips and debris after milling of a motor housing. Background Art

[0002] The motor housing is an external shell that protects the internal components of the motor and provides a supporting structure. It is usually installed on the outside of the motor to protect, dissipate heat and fix the motor. The motor housing is made of a variety of materials, including aluminum alloy, cast iron and steel. Among them, aluminum alloy motor housings are widely used due to their light weight, good heat dissipation and corrosion resistance. When milling aluminum alloy motor housings, aluminum chips will be generated. The aluminum chips are small and soft, and appropriate chip removal measures must be taken to prevent blockage and affect subsequent processes.

[0003] In the prior art, after some large aluminum motor casings are milled, workers mostly use hand-held air pumps and air guns to clean the aluminum chips remaining in the inner cavity and outer wall of the motor casing. In this process, firstly, the worker needs to hold the air pump and air gun and move along the outer wall of the motor to clean various places on the outer wall of the motor. The cleaning process is relatively time-consuming. Secondly, when it is necessary to clean the inner cavity of the motor casing, the worker needs to lift the heavy motor casing to facilitate the air pump and air gun to enter the inner cavity of the motor casing, which can easily cause worker fatigue, increase operating inconvenience and the safety hazard of the motor casing injuring the worker. Finally, manual cleaning is prone to missing some aluminum chips, affecting the cleaning effect, and may even cause problems during subsequent assembly or use. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that after some large aluminum motor casings are milled, most workers use hand-held air pumps and air guns to clean the aluminum chips remaining in the inner cavity and outer wall of the motor casing. In this process, firstly, the worker needs to hold the air pump and air gun and move along the outer wall of the motor to clean various places on the outer wall of the motor. The cleaning process is relatively time-consuming. Secondly, when the inner cavity of the motor casing needs to be cleaned, the worker needs to lift the heavy motor casing to facilitate the air pump and air gun to enter the inner cavity of the motor casing, which can easily cause worker fatigue, increase operating inconvenience and the safety hazard of the motor casing injuring the worker. Finally, manual cleaning is likely to miss some aluminum chips, affecting the cleaning effect, and may even cause problems in subsequent assembly or use.

[0015] The method for cleaning aluminum chips and debris after the motor housing is milled includes the following steps:

[0016] S1, loading the motor casing. The worker first lifts the closed folding cover by flipping the handle. The closed folding cover drives the guide plate in the auxiliary feeding mechanism to relax to a horizontal state through the linkage lifting assembly. The worker pushes the motor casing into the stepped cavity of the support plate through the guide plate. Both the external cleaning mechanism and the internal cleaning mechanism are on the top surface of the top connection frame.

[0017] S2, the outer wall and inner cavity of the motor casing are cleaned synchronously. The worker puts down the closed folding cover, and the closed folding cover drives the guide plate in the auxiliary feeding mechanism to be lifted to a vertical state through the linkage lifting assembly. The driving motor drives the external cleaning mechanism and the internal cleaning mechanism to move in the vertical direction at the same time. The air pump connected to the end of the common air pipe is used to blow away the aluminum chips remaining in the inner cavity and outer wall of the motor casing at the same time, and the aluminum chips remaining in the motor casing and the outside are gathered through the gathering bucket at the bottom of the closed box.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The present invention provides a top connection frame at the bottom of the inner cavity of the closed box, a support plate is provided inside the top connection frame, and a stepped cavity is provided inside the support plate. The stepped cavity is used to store a larger motor casing, and a synchronous cleaning component is provided inside the top connection frame. The synchronous cleaning component includes an external cleaning mechanism and an internal cleaning mechanism, which can simultaneously perform jet treatment on the outer wall of the motor casing placed inside the stepped cavity and the aluminum chips remaining in the inner cavity, which has many advantages. First, synchronous cleaning improves the cleaning efficiency, reduces the manual operation time of workers, and reduces labor intensity. Secondly, it avoids the safety hazards of workers lifting heavy objects and improves work safety. In addition, internal and external cleaning are carried out simultaneously, which ensures the comprehensive cleaning of aluminum chips, improves the cleaning effect, and reduces the impact of residual aluminum chips on subsequent assembly or motor operation.

[0020] 2. The present invention is provided with an auxiliary feeding mechanism in the gap between the top frame and the support plate, and a linkage lifting assembly is provided between the auxiliary feeding mechanism and the closed folding cover of the closed box. When the closed folding cover is lifted, the linkage lifting assembly can control the auxiliary feeding mechanism to fill the gap between the top frame and the support plate, so that the workers can feed the motor casing into the stepped cavity of the support plate. When the closed folding cover is lowered, the closed box is closed, and finally the cleaning process of the motor casing is completely carried out in a closed environment to protect the environment. The linkage lifting assembly can control the auxiliary feeding mechanism to move away from the gap between the top frame and the support plate to prevent the aluminum chips sprayed off the outer wall of the motor casing from being retained on the top of the auxiliary feeding mechanism, resulting in the problem that the subsequent aggregation of the aluminum chips takes a long time.

[0021] 3. The internal cleaning mechanism and the external cleaning structure of some cleaning equipment in the prior art are mostly directly connected to the air pipe. When the internal cleaning mechanism and the external cleaning structure are displaced in the vertical direction, the air pipe will be pushed, and the air pipe will be worn in the process. Even if a tank chain is provided, the tank chain will be worn after long-term use, which increases the maintenance cost and labor cost. However, the present invention has a distribution pipe fixedly arranged at the bottom of the side of the internal guide box and the external guide box, and a common air pipe is arranged at the end of the distribution pipe. The common air pipe can be connected to an air pump. When the internal cleaning mechanism and the external cleaning structure are displaced in the vertical direction, clean gas can be continuously obtained through the internal guide box and the external guide box. There is no displaced air pipe, which greatly reduces the maintenance cost and labor cost. BRIEF DESCRIPTION OF THE DRAWINGS

When the worker lifts the closed folding cover 14 by flipping the handle 9 and is ready to put the motor housing to be cleaned into the closed box 18, the closed folding cover 14 is wound around the pulling rope 2 through the top rope pulley 1, driving the counterweight column 4 to move upward, and the guide plate 13 is relaxed to a horizontal state due to its own weight. At this time, the middle rope pulley 11 is wound around a certain amount of horizontal rope 5.

The outer wall of the internal guide box 31 is fixedly connected to one end of the horizontal rod 22, and the other end of the horizontal rod 22 is fixedly connected to the side of the inner cavity of the closed box 18. The vertical box 29 is movably inserted into the internal guide box 31 along the vertical direction. The top of the vertical box 29 is fixedly connected to the internal disk 27, and the outer wall of the internal disk 27 has an external nozzle 270 in a circular array, and the external nozzle 270 is inclined.

[0047] An internal screw barrel 30 is fixedly arranged in the inner cavity of the vertical box 29, and an internal screw 28 is screwed into the internal thread of the internal screw barrel 30.

[0049] The specific implementation steps and principles of the present invention are as follows:

[0050] In the initial state, the closed folding cover 14 is in a state of closing the side of the closed box 18, and the counterweight column 4 pulls the guide plate 13 to a vertical state through the horizontal rope 5 and the middle rope pulley 11. The external ring 26 and the internal disk 27 are both on the top surface of the support disk 210. The worker first lifts the closed folding cover 14 by flipping the handle 9. The closed folding cover 14 is wound around the pulling rope 2 through the top rope pulley 1, driving the counterweight column 4 to move upward. The guide plate 13 is relaxed to a horizontal state due to its own weight. At this time, the middle rope pulley 11 is wound around a certain amount of horizontal rope 5.

[0051] The worker puts down the closed folding cover 14, and the closed folding cover 14 drives the guide plate 13 in the auxiliary feeding mechanism to be lifted to a vertical state through the above-mentioned linkage lifting assembly. The driving motor 17 drives the internal screw 28 and the external screw 36 to rotate simultaneously through the first pulley 23, the second pulley 25, and the transmission belt 24. The internal screw 28 and the external screw 36 drive the internal screw barrel 30 and the external screw barrel 34 to move upward in reverse order, driving the internal disk 27 and the external ring 26 to move in the vertical direction, and through the common air pipe 39 The external air pump, external guide hole 350, internal guide hole 320, internal nozzle 261 and external nozzle 270 spray out the aluminum chips remaining on the inner and outer walls of the motor casing. The aluminum chips remaining on the inner and outer walls of the motor casing eventually fall into the gathering bucket 7, driving the external cleaning mechanism and the internal cleaning mechanism to move in the vertical direction at the same time. The external air pump at the end of the common air pipe 39 blows out the aluminum chips remaining in the inner cavity and outer wall of the motor casing at the same time, and the aluminum chips remaining in the motor casing and the outside are gathered through the gathering bucket 7 at the bottom of the closed box 18.
