Description

Technical Field

[0001] This utility model relates to the field of aero-engine component manufacturing technology, specifically to a borescope cover retaining ring installation fixture. Background Technology

[0002] Borehole probes are used in the aerospace field to detect internal damage in aircraft engines, turbine blades, and other components, playing a crucial role in ensuring flight safety. Borehole probes come in various specifications, and the borehole cover retainers are often non-standard parts. To adapt to the upgrading of engine products and achieve suitable economic benefits, large-scale mass production using specialized equipment is not feasible. Therefore, the production tooling equipment needs to offer advantages such as low investment, stable performance, and the ability to improve production quality and efficiency.

[0003] Currently, when using tooling to assemble the hole cover retaining ring (see...), Figure 1 The process of assembling the hole cover retaining ring 6 into the gap of the cylinder 7 to block the plug 4, and assembling the plug 4, hole cover retaining ring 6, cylinder 7, spring 8, and push rod 9 into a whole has the following problems: 1. It requires two workers to work together, which increases labor costs and has low assembly efficiency; 2. The workers are prone to damage to parts during the assembly process. Utility Model Content

[0004] The purpose of this utility model is to provide a hole cover retaining ring installation fixture for borehole probes that solves the above-mentioned problems. It is simple in structure, reliable in use, and low in manufacturing cost. Compared with existing fixtures, it is simple to operate and can be completed by one worker, saving labor costs. It is highly practical, effectively improving production efficiency, while avoiding damage to parts due to improper personnel coordination, ensuring product quality, and reducing product manufacturing costs.

[0005] The technical solution of this utility model is:

[0006] A borescope cover retainer mounting fixture includes a base. The key technical features are: the upper surface of the base has a lower positioning hole corresponding to the cylinder body; a top cover is fixed to the top of the base using positioning bolts; the top cover has an upper positioning hole corresponding to a plug; the center lines of the upper and lower positioning holes coincide; a pressure rod is provided on the side of the base; the upper end of the pressure rod is used to connect to a press; the lower end of the pressure rod has a pressure head; and the end of the pressure head extends between the base and the top cover.

[0007] The aforementioned borehole cover retaining ring installation fixture has upright plates on the front and rear sides of the base, and the two upright plates form a sliding groove for the corresponding top cover. The side of the base has a positioning groove for the corresponding positioning bolt, and the side of the top cover has a fixing hole for connecting with the positioning bolt.

[0008] The aforementioned borehole cover retaining ring installation fixture has a vertical extrusion section at the end of the pressure head. The lower end of the vertical extrusion section is located above the gap between the cylinder and the plug, and the lower end dimension of the vertical extrusion section is smaller than the width of the gap.

[0009] In the aforementioned borehole cover retaining ring installation fixture, the fixed end of the pressure head is connected and fixed to the pressure rod using a pin.

[0010] The beneficial effects of this utility model are:

[0011] This tooling was designed to simplify the installation of the cap retainer, prevent damage to mating parts, and ensure stable machining. In use, the cylinder and plug are assembled and positioned using the lower positioning hole on the base and the upper positioning hole on the top cover. Then, the vertical pressing part of the pressure head presses down on the cap retainer, causing a portion to enter the groove in the cylinder. Rotating the cylinder then fully engages the retainer, locking the plug in place and preventing it from detaching from the cylinder. The entire process can be operated by one person, saving labor costs, offering high practicality, effectively improving production efficiency, preventing damage to parts due to improper personnel coordination, resulting in high product quality and reduced manufacturing costs.

[0014] The present invention will be described in detail with reference to the accompanying drawings.

[0015] like Figure 1 As shown, the borehole cover retaining ring installation fixture for the borehole probe includes a base 3. The upper surface of the base 3 is provided with a lower positioning hole 301 corresponding to the cylinder 7. A top cover 2 is fixed above the base 3 by positioning bolts 10. The top cover 2 is provided with an upper positioning hole 201 corresponding to the plug 4. The center lines of the upper positioning hole 201 and the lower positioning hole 301 coincide. A pressure rod 1 is provided on the side of the base 3. The upper end of the pressure rod 1 is used to connect to a press. The lower end of the pressure rod 1 is provided with a pressure head 5. The end of the pressure head 5 extends between the base 3 and the top cover 2.

[0016] In this embodiment, the base 3 has upright plates on its front and rear sides, forming sliding grooves corresponding to the top cover 2. The base 3 has positioning grooves 302 on its side corresponding to the positioning bolts 10. The top cover 2 has fixing holes on its side for connection with the positioning bolts 10. The top cover 2 can move vertically up and down along the sliding grooves and can be vertically positioned by the positioning bolts 10. The end of the pressure head 5 has a vertical pressing part 501. The lower end of the vertical pressing part 501 is located above the gap between the cylinder 7 and the plug 4, and the lower end dimension of the vertical pressing part 501 is smaller than the width of the gap. The fixed end of the pressure head 5 is connected and fixed to the pressure rod 1 using a pin.

[0017] Operating instructions:

[0018] 1. Place the base 3 on the workbench, insert the lower part of the cylinder 7 into the lower positioning hole 301 of the base 3, put the spring 8 on the top rod 9 and insert the cylinder 7, put the hole cover retainer 6 on the plug 4, insert the upper part of the plug 4 into the upper positioning hole 201 of the top cover 2, insert the lower part of the plug 4 into the cylinder 7, apply downward pressure to the top cover 2 to ensure that the spring 8 is compressed by about 1 / 3, and tighten the positioning bolt 10 to ensure that the top cover 2 and the base 3 will not have relative displacement.

[0019] 2. Connect the pressure rod 1 to the press, and ensure that the vertical pressing part 501 of the pressure head 5 is pressed tightly against the plug 4, guaranteeing that the orifice cap retaining ring 6 is positioned between the pressure head 5 and the cylinder 7. Use tweezers to insert the orifice cap retaining ring 6 into the gap between the plug 4 and the cylinder 7. Start the press to apply force, pressing the orifice cap retaining ring 6 into the groove of the cylinder 7, then stop applying force. Rotate the cylinder 7 to the left until the orifice cap retaining ring 6 is fully pressed into the groove, completing the installation.
