Description

Technical Field

[0001] This utility model relates to the field of blade processing technology, and in particular to a grinding device for grinding aero-engine blades. Background Technology

[0002] Grinding is a crucial step in the production of aero-engine blades. Due to the complex structure of aero-engine blades, automated grinding is difficult or too costly. Currently, aero-engine blade grinding is mainly done manually. This grinding is conducted in an open environment, where grinding debris is splashed into the air. Wearing masks alone is insufficient to protect workers from the debris, which can easily cause injury. Furthermore, the debris cannot be effectively collected.

[0003] Furthermore, the large amount of shavings generated during the grinding process of aero-engine blades can interfere with the working vision of the grinding operators, easily leading to improper operation and causing grinding tools to fly out, resulting in scratches, cuts, and other injuries to the grinding operators. At the same time, the high noise generated during the grinding process in an open work environment can easily damage the hearing of the grinding operators. Therefore, there is an urgent need for a grinding device that can prevent grinding shavings from flying into the grinding operators and causing injury. Summary of the Invention

[0004] The purpose of this invention is to overcome at least one deficiency of the prior art and provide a grinding device for grinding aero-engine blades that helps to prevent grinding debris generated during the grinding operation from splashing onto the grinding operator and causing injury to the operator.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A grinding apparatus for grinding aero-engine blades according to this application includes:

[0007] Support base;

[0008] A protective cover is installed on the support base, and a grinding operation cavity is formed inside the protective cover. A grinding clearance opening communicating with the grinding operation cavity is provided on one side of the protective cover in the horizontal direction, and an observation opening communicating with the grinding operation cavity is provided on the top plate of the protective cover.

[0009] A transparent observation window is installed on the top plate of the protective cover and covers the observation opening.

[0010] The beneficial effects of this utility model are as follows: In this embodiment, a protective cover is provided, inside which a grinding chamber is provided, and a transparent observation window is installed on the observation opening of the top plate of the protective cover. Thus, the grinding operator can insert both hands into the grinding chamber from the outside of the protective cover through the grinding clearance opening to operate the grinding mechanism. This allows the aero-engine blades to be ground inside the grinding chamber. During the grinding process, the protective cover can block the grinding debris generated during the grinding operation, and it is easy to observe the grinding operation inside the grinding chamber through the transparent observation window. The position of the aero-engine blade to be ground can be flexibly adjusted according to the grinding operation requirements, so that the position of the aero-engine blade to be ground is accurately ground by the grinding mechanism. It also helps to prevent the grinding debris generated during the grinding operation from splashing onto the grinding operator and causing injury to the grinding operator.

[0011] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0012] According to one embodiment of the present invention, the bottom plate of the protective cover of the grinding device for grinding aero-engine blades is provided with a slag removal port communicating with the grinding working chamber. The grinding device for grinding aero-engine blades further includes:

[0013] A slag collection box is installed on the lower side of the base plate of the protective cover, and a slag collection cavity is formed inside the slag collection box that communicates with the slag removal port.

[0014] The shavings collection box provided in this embodiment can collect the shavings that fall from the shavings removal port, so that the shavings in the grinding chamber can be cleaned in time, avoiding the accumulation of shavings in the grinding chamber, which would affect the work of the grinding operators, improve the safety of the grinding environment and the grinding efficiency of the grinding operators.

[0015] According to one embodiment of the present invention, the grinding debris collection box of the grinding device for grinding aero-engine blades includes:

[0016] The housing body is installed on the lower side of the bottom plate of the protective cover.

[0017] A rotating door is rotatably mounted on the second observation opening, and the rotating door has an open position and a closed position relative to the main body of the box.

[0018] In this embodiment, a rotating door is provided, which can be controlled between the open and closed positions. When the rotating door is in the open position, the rotating door and the housing body form a visible channel, making it convenient for the grinding operator to observe the amount of grinding shavings in the grinding shavings collection chamber and to clean the grinding shavings on the inner wall of the housing body. When grinding is being performed, the rotating door is placed in the closed position, and the grinding shavings that fall during the grinding operation will be collected in the grinding shavings collection chamber, preventing the grinding shavings in the grinding shavings collection box from spreading outward.

[0019] According to one embodiment of the present invention, the shavings collection box is provided with a second shavings removal port that communicates with the shavings collection cavity, and a shavings removal drawer is movably installed on the second shavings removal port, the shavings removal drawer extending into the shavings collection cavity.

[0020] In this embodiment, the slag removal drawer is movably installed on the slag removal opening two. Slag is deposited in the slag removal drawer. The grinding operator removes the slag removal drawer from the slag removal opening two, removes the slag from the drawer, and then reinstalls the slag removal drawer back onto the slag removal opening two. This facilitates the removal of slag from the slag collection box and is easy to operate.

[0021] According to one embodiment of the present invention, the grinding debris collection box is provided with an exhaust port communicating with the grinding debris collection cavity on one side in the horizontal direction, and an exhaust device is installed at the exhaust port.

[0022] In this embodiment, an exhaust device is installed at the exhaust port. The suction generated by the exhaust device during operation will draw the grinding debris generated in the grinding operation chamber into the grinding debris collection chamber through the grinding debris removal port. This facilitates timely cleaning of the grinding debris generated during the grinding process, prevents the grinding debris from splashing out and interfering with the grinding operation personnel, and improves production safety.

[0023] According to one embodiment of the present invention, the bottom plate of the protective cover is provided with a plurality of shavings falling inlets communicating with the grinding operation cavity, and the shavings removal outlet includes a plurality of shavings falling inlets.

[0024] In this embodiment, multiple swarf drop outlets are provided. The swarf generated during the grinding process falls into the swarf collection box through these outlets. The grinding operation can be carried out on the swarf removal outlet, which increases the amount of swarf falling and prevents the aero-engine blades from falling directly into the swarf collection box from the swarf removal outlet.

[0025] According to one embodiment of the present invention, the grinding device for grinding aero-engine blades further includes:

[0026] A shock-absorbing pad is installed on the inner side of the base plate of the protective cover. The shock-absorbing pad has a third abrasive cleaning port that communicates with the first abrasive cleaning port in the vertical direction.

[0027] In this embodiment, by providing a shock-absorbing pad, the grinding operator works on the shock-absorbing pad, which reduces the vibration generated during the grinding process between the grinding tool and the workpiece, reduces the fatigue caused by vibration during the grinding operation, and improves the work efficiency of the grinding operator.

[0028] According to one embodiment of the present invention, the grinding device for grinding aero-engine blades further includes:

[0029] Flame-retardant sound-absorbing components are installed on the inner wall of the protective cover.

[0030] In this embodiment, a flame-retardant sound-absorbing component is provided, which can absorb sound and retard flames.

[0034] According to one embodiment of the present invention, the top plate of the protective cover of the grinding device for grinding aero-engine blades includes:

[0035] Horizontal plate;

[0036] An inclined movable plate is rotatably mounted on the horizontal plate, and the inclined movable plate is provided with the observation port one.

[0037] In this embodiment, the tilting movable plate is rotatably mounted on the horizontal plate, which allows the grinding operator to rotate the tilting movable plate so that the position of the tilting movable plate forms a placement opening for placing the aero-engine blades. This makes it easy for the grinding operator to put the aero-engine blades into the grinding working chamber or take the aero-engine blades out of the grinding working chamber through the placement opening.

[0038] According to one embodiment of the present invention, the grinding device for grinding aero-engine blades further includes:

[0039] The grinding mechanism is movably disposed within the grinding operation cavity.

[0040] In this embodiment, by movably setting the grinding mechanism inside the grinding operation cavity, it is beneficial for the grinding operator to flexibly operate the grinding mechanism to grind the aero-engine blades according to the grinding operation requirements, and it is also labor-saving.

[0041] According to one embodiment of the present invention, the grinding device for grinding aero-engine blades further includes:

[0042] The support member is detachably mounted on the protective cover and is located on the same side as the grinding clearance opening. The lower side of the inclined movable plate at the end away from the horizontal plate abuts against the upper end of the support member.
