Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a heat treatment fixture for steel parts on aircraft. Background Technology

[0002] Steel parts are widely used in aircraft. Most parts require heat treatment after forming to improve their mechanical properties, machinability, eliminate work hardening, release residual stress, and increase hardness. During heat treatment, the parts will deform due to high temperatures, requiring manual correction by fitters. The increased hardness of the parts after heat treatment makes correction difficult, labor costs high, and consistency cannot be guaranteed by manual correction.

[0003] To address this issue, we propose a heat treatment fixture for steel parts used in aircraft. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technology where parts deform after being subjected to high temperatures, requiring manual correction by fitters, increasing the hardness of parts after heat treatment, making correction difficult, costly, and unable to guarantee consistency. Therefore, a heat treatment fixture for steel parts on aircraft is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heat treatment fixture for steel parts on an aircraft includes a lower mold body, an upper mold body is engaged above the lower mold body, positioning components are inserted into the lower mold body and the upper mold body, and a limiting wedge is inserted at the top of the positioning components. Eye bolts are installed on both sides of the lower mold body and the upper mold body.

[0006] Preferably, the positioning component includes a plug-in post, which is inserted into the lower mold body and the upper mold body, and the lower end of the plug-in post is fixedly connected to a limit plate.

[0007] Preferably, the insertion post is cylindrical, and the lower mold body and the upper mold body are provided with round holes at the four corners that are adapted to the insertion post.

[0008] Preferably, the surface diameter of the limiting plate is larger than the surface diameter of the insertion post, and grooves adapted to the limiting plate are provided at the four corners of the lower surface of the lower mold body.

[0009] Preferably, the upper surface of the limiting wedge is provided with an inclined surface, and a through hole adapted to the limiting wedge is opened inside the upper part of the insertion post.

[0010] Preferably, reference holes are provided on both sides of the opposite side of the lower mold body and the upper mold body.

[0011] Preferably, two eye bolts are symmetrically installed on one side of both the lower and upper mold bodies.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This device allows the part to be clamped between the lower and upper mold bodies by passing the positioning component through the lower mold body and inserting the limiting wedge into the positioning component. This effectively fixes the part, preventing deformation and springback during high-temperature heat treatment. It also reduces the difficulty of manual shaping later. Furthermore, when the part size is small, one set of lower and upper mold bodies can clamp multiple parts during heat treatment, greatly improving production efficiency and reducing labor costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3 A heat treatment fixture for steel parts on an aircraft includes a lower mold body 1, an upper mold body 2 that is engaged above the lower mold body 1, a positioning component 3 inserted inside the lower mold body 1 and the upper mold body 2, and a limiting wedge 4 inserted at the top of the positioning component 3, and eye bolts 5 installed on both sides of the lower mold body 1 and the upper mold body 2.

[0017] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the positioning component 3 includes a plug-in post 31. The plug-in post 31 is inserted into the lower mold body 1 and the upper mold body 2, and the lower end of the plug-in post 31 is fixedly connected to the limit plate 32. The lower mold body 1 and the upper mold body 2 can be assembled and used through the plug-in post 31.

[0018] Furthermore, refer toFigure 2 and Figure 3 It can be seen that the insertion post 31 is cylindrical, and round holes adapted to the insertion post 31 are opened at the four corners of the lower mold body 1 and the upper mold body 2. The insertion of the insertion post 31 can be facilitated by the round holes opened at the four corners of the lower mold body 1 and the upper mold body 2.

[0019] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the surface diameter of the limiting plate 32 is larger than the surface diameter of the insertion post 31. The limiting plate 32 can conveniently limit the function of the insertion post 31. The four corners of the lower surface of the lower mold body 1 are provided with grooves that are compatible with the limiting plate 32. The grooves provided at the four corners of the lower surface of the lower mold body 1 can conveniently accommodate the insertion post 31.

[0020] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the upper surface of the limiting wedge 4 is provided with an inclined surface. By setting the upper surface of the limiting wedge 4 as an inclined surface, it can be convenient to squeeze and limit each other with the insertion post 31. The upper interior of the insertion post 31 is provided with a through hole that matches the limiting wedge 4. Through the through hole opened in the upper interior of the insertion post 31, the limiting wedge 4 can be inserted into the through hole, which facilitates the function of limiting the insertion post 31 and makes it easier for the lower mold body 1 and the upper mold body 2 to clamp the part.

[0021] Furthermore, refer to Figure 2 and Figure 3 It can be seen that reference holes 6 are provided on both sides of the opposite side of the lower mold body 1 and the upper mold body 2. Two reference holes 6 are provided on the opposite side of the lower mold body 1 and the upper mold body 2, which can be used as references for mold processing.

[0022] Furthermore, refer to Figure 1 and Figure 2 It can be seen that two eye bolts 5 are symmetrically installed on one side of both the lower mold body 1 and the upper mold body 2. By installing two eye bolts 5 on one side of both the lower mold body 1 and the upper mold body 2, it is convenient to move the lower mold body 1 and the upper mold body 2.

[0023] Working principle: When this utility model is in use, when the current mold 1 is in use, according to the attached... Figure 1 Appendix Figure 2 and attached Figure 3By inserting the plug pins 31 into the four corners of the lower mold body 1 and the upper mold body 2, and then placing the part on the surface of the lower mold body 1, the upper mold body 2 can be pressed onto the lower mold body 1. The plug pins 31 can guide the placement of the upper mold body 2, and the reference hole 6 can ensure the accuracy of the engagement between the lower mold body 1 and the upper mold body 2. Then, the limiting wedge 4 is passed through the through hole opened above the plug pin 31, and after being hammered and tightened, the lower mold body 1 and the upper mold body 2 are moved by the eye bolts 5 and placed in the heat treatment furnace for heat treatment. The above is the complete working principle of this utility model.
