Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, and in particular to a mounting seat hole closing tool, equipment and method. Background Art

[0002] In the field of aero-engines, the precision and reliability of parts are crucial, especially those located in key connection parts. For a certain type of aero-engine parts, the material is a difficult-to-process high-temperature alloy GH3536. GH3536 high-temperature alloy is known for its high strength, excellent corrosion resistance and heat resistance, but also because of its high hardness and toughness, it is easy to produce thermal deformation during processing, affecting the precision of the parts. The wall thickness of the part is 1.2mm~1.4mm, and the overall rigidity of the part is poor. In order to ensure the stability and other performance of the engine, the part is designed with 12 evenly distributed support mounts on the small end shape. There is also a boss on the outer circle of each mount. It is necessary to install a ball head seat and a ball head in each mounting seat hole. The ball head is rotatably connected to the inside of the ball head seat. In order to prevent the ball head seat of the part from falling out, the boss on the outer circle of the support mount needs to be closed at 60°, that is, the diameter is reduced. Because the ball head in the support mounting seat is the key part connecting the flame tube and the engine combustion chamber, the ball head is required to rotate flexibly and freely so that the positioning pin can accurately enter the ball head for connection when the combustion chamber components are assembled. Therefore, the closing quality must be guaranteed after the support pin mounting seat is assembled with the ball head seat. Due to the difficult processing of GH3536 high-temperature alloy, as well as the poor overall rigidity of the parts and the complex structure, this closing process becomes particularly difficult.

[0003] The traditional closing method uses the impact method to close the mouth. Due to the influence of the part structure, the front end face of the support mounting seat needs to be supported on a temporary pressure plate during processing. Then two people hold the part down, and one person uses a hammer to manually hit the punch to perform the closing operation. When operating this method, it is necessary to visually check that the punch and the support mounting seat hole are on the same axis. Due to individual differences, there is a situation where the closing is not straight, with more on one side and less on the other side. Since the impact closing method is used, the closing part is prone to peeling due to different personal strength during the closing process. At the same time, knocking is prone to cracks and deformation, affecting the quality of the part. Therefore, the traditional closing method is not only time-consuming and labor-intensive, but also difficult to ensure the closing quality and easy to cause damage to the parts, resulting in low overall part production efficiency, low qualified rate of finished parts, and high cost.

[0004] To address the above issues, it is necessary to explore technology, utilize existing production conditions, and innovate processing methods to solve the problem of closing the support mounting seat after assembling the ball head seat and the ball head, ensure the processing quality and efficiency of the parts, improve the processing quality of the parts, and make the parts meet the performance requirements of aircraft engines. Summary of the invention

[0005] In view of the problems in the prior art that closing of a mounting seat is prone to damage of parts, low closing efficiency and high cost, the present invention provides a tool, equipment and method for closing a mounting seat hole.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A mounting seat hole closing tool, comprising a body and a top; The front end of the body is provided with a front tongue; when closing, the front tongue cooperates with the U-shaped space between the part and the support mounting seat; The tip is arranged inside the main body and can move in the horizontal direction of the main body; a closing groove is arranged at one end of the tip close to the front end tongue, and the angle between the groove wall of the closing groove and the horizontal direction is equal to the angle between the side wall of the boss after closing and the horizontal direction; the other end of the tip is provided with a pushing device, which is used to push the tip to move toward the part direction to close the boss.

[0007] Optionally, the jacking device includes a clamping screw, which passes through the rear end of the body and is connected to the rear end of the top.

[0008] Optionally, the pressing screw is connected to the top through a cylindrical pin.

[0009] Optionally, one end of the compression screw away from the top end is detachably connected with a movable handle.

[0010] Optionally, a stopper is provided at one end of the front end tongue close to the top end, and a curved surface is provided at the bottom of the stopper, and when closing, the curved surface fits against the outer wall of the support mounting seat.

[0011] Optionally, a key slot is provided on the main body, and the key slot is parallel to the axis of the support mounting seat and is located directly above the axis of the support mounting seat.

[0012] Optionally, a locating pin is radially arranged on the top edge, and the free end of the locating pin is inserted into the keyway and can move freely inside the keyway along the axial direction of the support mounting seat.

[0013] Optionally, a handle is also provided on the body.

[0014] A parts processing equipment comprises the above-mentioned mounting seat hole closing tool.

[0015] A method for closing a mounting seat hole using the above-mentioned closing tool comprises: Place the front tongue against the inside of the U-shaped space between the part and the support mounting seat and fit it against the inner wall of the U-shaped space; Make the axis of the top coincide with the axis of the support mounting seat, and make the end of the boss abut against the side wall of the closing groove; The jacking tip moves toward the part until the outer wall of the boss is completely fitted with the side wall of the closing groove to complete the closing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a tool for closing a seat hole, comprising a body and a top. A front end tongue is arranged at the front end of the body. When closing, the front end tongue is matched with a U-shaped space between a part and a support mounting seat. The tool can be stably positioned in the U-shaped space between the part and the support mounting seat, thereby ensuring the stability and accuracy of the closing process. The matching of the front end tongue with the U-shaped space between the part and the support mounting seat can effectively avoid the deformation of the thin wall of the part under stress during the closing process. The top is arranged inside the body, moves along the horizontal direction of the body, and a closing groove is arranged at one end of the top close to the front end tongue. By making the angle between the groove wall of the closing groove and the horizontal direction equal to the angle between the side wall of the boss after closing and the horizontal direction, during the closing process, the closing can be ensured to meet the accuracy requirements of the closing angle, and the problem of inconsistent closing caused by different personal operations can be effectively avoided. By arranging a jacking device at the other end of the top, the jacking top is moved toward the part direction to close the boss, and the boss is closed, and the deformation and peeling of the closing part will not be caused by different personal operation strength. The tool has a simple structure and is easy to operate. It can not only achieve precise closing, but also save a lot of manpower and improve the closing efficiency and quality.

[0017] The jacking device includes a clamping screw rod, which passes through the rear end of the body and is connected to the rear end of the top. Through the arrangement of the clamping screw rod, when closing the mouth, the top can be pushed forward by rotating the screw rod to close the boss, which has a simple structure, low processing cost and can provide sufficient jacking force.

[0018] The clamping screw is connected to the top through a cylindrical pin, which ensures a firm connection between the clamping screw and the top, prevents loosening or falling off during the jacking process, and improves the reliability and safety of the tool.

[0019] The end of the compression screw away from the top is detachably connected with a movable handle, and the design of the movable handle allows the operator to conveniently rotate the compression screw to perform the jacking operation. At the same time, the detachability of the handle also facilitates the carrying and storage of the tool.

[0020] The end of the front tongue near the tip is provided with a stopper, and the bottom of the stopper is provided with an arc surface, and when closing the mouth, the arc surface fits with the outer wall of the support mounting seat. The setting of the stopper further improves the stable positioning of the tool when closing the mouth, and prevents deviation during the closing process. The arc surface at the bottom of the stopper fits with the outer wall of the support mounting seat, which can effectively position the tool and prevent the tool from damaging the outer wall of the support mounting seat.

[0021] The body is provided with a keyway, which is parallel to the axis of the support mounting seat and is located directly above the axis of the support mounting seat. The design of the keyway enables the top to remain parallel to the axis of the support mounting seat during movement, thereby ensuring the accuracy and consistency of the closing.

[0022] A positioning pin is radially arranged on the top of the top, and the free end of the positioning pin is inserted into the keyway and can move freely in the keyway along the axis direction of the support mounting seat. The positioning pin is inserted into the keyway, which further limits the moving direction of the top, so that the top pushing direction is always parallel to the axis of the support mounting seat, further improving the stability and accuracy of the closing process.

[0023] The main body is also provided with a handle, which is convenient for the operator to hold, apply force and move the tool, thereby improving the convenience and efficiency of operation.

[0024] The present invention also provides a parts processing equipment, including the above-mentioned mounting seat hole closing tool, which can realize automatic or semi-automatic closing operation and improve production efficiency and processing quality.

[0025] The present invention also provides a method for closing the above-mentioned mounting seat hole closing tool, which ensures the stability of the closing tool by making the front end tongue press against the inside of the U-shaped space between the part and the supporting mounting seat and fit with the inner wall of the U-shaped space; then the axis of the top is made to coincide with the axis of the supporting mounting seat, and the end of the boss is made to press against the side wall of the closing groove, further ensuring the stability, accuracy and consistency of the closing; finally, by pushing the top toward the part until the outer wall of the boss is completely fitted with the side wall of the closing groove, the boss can be accurately closed, improving the processing quality and performance of the part. The method is simple, easy to operate and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0044] See also Figure 1 and Figure 2 For a certain type of aircraft engine parts, the material is the difficult-to-process high-temperature alloy GH3536. The GH3536 high-temperature alloy is known for its high strength, excellent corrosion resistance and heat resistance, but also because of its high hardness and toughness, it is easy to produce thermal deformation during the processing process, affecting the accuracy of the parts. The wall thickness of the part is as high as 1.2mm~1.4mm, and the overall rigidity of the part is poor. In order to ensure the stability and other performance of the engine, the part is designed with 12 evenly distributed support mounting seats 10 on the small end shape. A boss 11 is also provided on the outer circle of each support mounting seat 10. A ball head seat 12 and a ball head 13 need to be installed in the hole of each support mounting seat 10. The ball head 13 is rotatably connected to the inside of the ball head seat 12. In order to prevent the ball head seat 12 of the part from falling out, the boss on the outer circle of the support mounting seat 10 needs to be subjected to a 60° closing treatment, that is, a diameter reduction treatment. See the structure after treatment. Figure 2Since the ball head 13 in the support mounting seat 10 is the key part for connecting the flame tube and the engine combustion chamber, the ball head 13 is required to rotate flexibly and freely so that the positioning pin can accurately enter the ball head 13 for connection when the combustion chamber components are assembled. Therefore, the quality of the closing must be ensured after the support mounting seat 10 is assembled with the ball head seat 12. Due to the difficult processing of the GH3536 high-temperature alloy, the poor overall rigidity of the parts, the complex structure and other factors, this closing process becomes particularly difficult.

[0050] Example 4 See also Figures 3 to 6The present invention provides a mounting seat hole closing tool, comprising a body 1 and a top 2; the top 2 is located inside the body 1 and moves in the horizontal direction; the body 1 is provided with a handle 3, and optionally, the handle 3 is installed at the rear end of the body 1; the front end of the body 1 is provided with a front tongue 4, and when closing, the front tongue 4 cooperates with the U-shaped space between the part and the supporting mounting seat 10; the end of the front tongue 4 close to the top 2 is provided with a stopper 6, and the bottom of the stopper 6 is provided with an arc surface, and when closing, the arc surface and the supporting mounting seat 10 The outer wall is fitted, and optionally, the stopper 6 is connected to the main body 1 by a countersunk screw; the top 2 can move in the horizontal direction of the main body 1, and a closing groove 14 is provided at one end of the top 2 close to the front end tongue 4, and the angle between the groove wall of the closing groove 14 and the horizontal direction is 30°; a clamping screw 5 is provided at the other end of the top 2, and the clamping screw 5 passes through the rear end of the main body 1 and is connected to the rear end of the top 2, optionally, the clamping screw 5 is connected to the top 2 by a cylindrical pin 7, and the end of the clamping screw 5 away from the top 2 is detachably connected with a movable handle 9.

[0051] A key slot 15 is provided on the main body 1, and the key slot 15 is parallel to the axis of the support mounting seat 10 and is located directly above the axis of the support mounting seat 10; a locating pin 8 is radially arranged on the top 2, and the free end of the locating pin 8 is inserted into the key slot 15 and can move freely inside the key slot 15 along the axis direction of the support mounting seat 10, so as to control the moving stroke of the top 2. Optionally, when the locating pin 8 moves to the end of the key slot 15 close to the part, the closing size requirement at the closing place is just reached.

[0052] See also Figures 7 and 8 , first place the part with the large end facing down on the platform, then hold the handle 3 with one hand to pick up the closing tool, and use the other hand to rotate the movable handle 9 to adjust the distance between the top 2 and the body 1 to be greater than the axial length of the support mounting seat 12, and place the tool on the outer diameter of the support mounting seat 10 to ensure that the stopper 6 fits the outer diameter of the support mounting seat 10, and put the front end tongue 4 on the body 1 into the U-shaped space of the support mounting seat 10 of the part, and fit it with the front end surface of the support mounting seat 10, so that the end of the boss 11 conflicts with the side wall of the closing groove 14 in the top 2, and the top 2 is driven to move in the closing direction by rotating the movable handle 9. The closing part of the step 11 will be evenly squeezed and will enter the 60° tapered hole on the top 2, that is, the closing groove 14. When the cylindrical pin 8 on the top 2 moves to the limit position in the groove, the size requirement of the closing is met, the movable handle 9 is reversed, the top 2 retreats, and the tool is taken out. The closing is completed and the closing of the next support mounting seat 10 can be carried out.

[0053] See also Fig. 9 and Fig.10To further illustrate the beneficial effects of the present invention, the existing closing method is compared with the closing method of the present invention. The traditional closing method uses an impact method to close the mouth. Due to the influence of the part structure, it is necessary to support the front end surface of the support mounting seat against a temporary pressure plate during processing. Then two people hold the part, and one person manually knocks the punch with a hammer to perform the closing operation. It can be seen that due to different personal strengths, dense pits will be produced at the closing part after closing, the closing quality is poor, and there are safety hazards to the parts and operators during the knocking process. When the closing tool provided by the present invention is used for closing, it is only necessary to turn the movable handle 9 to easily achieve closing, and the surface of the closing part after closing is smooth without any pits or damage, which greatly improves the closing efficiency, closing quality and safety of closing operation.

[0054] The present invention also provides a parts processing equipment, including the above-mentioned mounting seat hole closing tool, which can realize automatic or semi-automatic closing operation, thereby improving production efficiency and processing quality.

[0056] The method ensures the stability of the closing tool by making the front end tongue 4 press against the inside of the U-shaped space between the part and the support mounting seat 10 and fit with the inner wall of the U-shaped space; then the axis of the top 2 is made to coincide with the axis of the support mounting seat 10, and the end of the boss 11 is made to press against the side wall of the closing groove 14, further ensuring the stability, accuracy and consistency of the closing; finally, by pushing the top 2 toward the part until the outer wall of the boss 11 is completely fitted with the side wall of the closing groove, the boss can be accurately closed, improving the processing quality and performance of the part. The method is simple, easy to operate and efficient.

[0057] In summary, the present invention provides a tool, device and method for closing the hole of a mounting seat, by setting a front end tongue at the front end of the body; when closing, by cooperating the front end tongue with the U-shaped space between the part and the supporting mounting seat; so that the tool can be stably positioned in the U-shaped space between the part and the supporting mounting seat, ensuring the stability and accuracy of the closing process, while effectively avoiding the deformation of the thin wall of the part due to the cooperation of the front end tongue with the U-shaped space between the part and the supporting mounting seat during the closing process.
