A rapid sleeve pressing device and method for band drill jig type tires

Abstract

The application provides a quick sleeve pressing device and method for a drill template type tire, which comprises a pressing fixing assembly and a sleeve pressing assembly. The pressing fixing assembly is used for fixing the drill template type tire to avoid movement of the drill template type tire during sleeve pressing. The sleeve pressing assembly comprises a mandrel, sleeve pressing guide columns and locking cross pins. The main body of the sleeve pressing guide column is a guide column, and a mounting plate is fixed to the lower end of the sleeve pressing guide column. The bottom surface of the mounting plate is fixed with the sleeve pressing guide column through the locking cross pins. The number and position of the sleeve pressing guide columns correspond to drill template holes on the drill template type tire, and the sleeve pressing guide columns are axially perpendicular. The sleeve pressing guide columns are used for mounting the bushings to be pressed. The application no longer needs to knock each drill sleeve for sleeve pressing, and all drill sleeves can be pressed into the drill template type tire by one-time knocking.

Description

Technical Field

[0001] This invention belongs to the field of machining technology and relates to a rapid pressing device and method for a die-type tire with a drill. Background Technology

[0002] There is a type of sheet metal part in aircraft that has holes and requires a drill-die type jig (e.g.) Figure 1 Forming and drilling: These perforated sheet metal parts are part of aircraft systems, and drill jig-type fixtures are essential tooling for forming and drilling these parts. Drill jig-type fixtures typically have multiple drill jig holes. Previously, drill bushings on these fixtures required manual hammering installation one by one. This method has several drawbacks: 1. Manual hammering installation is a single-piece installation, which is time-consuming. 2. Due to the lack of guidance, manual hammering installation greatly increases the possibility of axial misalignment of the installed drill bushings. 3. Because of axial misalignment issues during manual hammering installation, drill bushings are scrapped, requiring the machining of multiple drill bushings as spares, resulting in wasted machining time, materials, and time costs. Therefore, the installation method for drill bushings on drill jig-type fixtures needs optimization to improve installation efficiency. Summary of the Invention

[0003] Based on the structural characteristics and usage requirements of drill jig type jigs, a rapid pressing device and method for drill jig type jigs are provided to achieve rapid pressing of drill sleeves onto drill jig type jigs. It has the following functions:

[0004] ① The design incorporates a guiding mandrel to prevent axial deviations after drill bushing installation. ② The designed pressing device eliminates the need to individually tap each drill bushing; a single tap is sufficient to press all drill bushings into the jig-type mold. ③ Due to the guiding mandrel design, there is no need to machine multiple drill bushings as spare parts.

[0005] The technical solution adopted in this invention is as follows:

[0006] A quick pressing device for a die-type jig includes a pressing and fixing assembly and a pressing assembly. The pressing and fixing assembly is used to fix the die-type jig and prevent it from moving during the pressing process. The pressing assembly includes a mandrel 01, a pressing guide post 02, and a locking cross pin 03. The main body of the pressing guide post 02 is a guide post, and a mounting plate is fixed to its lower end. The mandrel 01 is fixed to the bottom surface of the mounting plate by the locking cross pin 03. The number and position of the mandrel 01 correspond to the drill holes on the die-type jig, and the mandrel 01 is axially perpendicular. The mandrel 01 is used to install the drill sleeve to be pressed.

[0007] The clamping and fixing assembly includes a slider 04, a stop block 05, a support plate 06, a clamping body 07, a handle nut 08, and a cover plate 09.

[0008] The clamping body 07 includes a base plate and an L-shaped upright plate, with the L-shaped upright plate fixed to the base plate. Two stop blocks 05, a cover plate 09, and a support plate 06 are fixedly connected to form a box structure. The stop blocks 05 are on both sides, and the cover plate 09 is fixed between the two stop blocks 05, with a guide post installed in the middle of its inner side. The support plate 06 is fixed to the top of the two stop blocks 05. The box structure has two sets, which are fixed to the horizontal and vertical side plates of the L-shaped upright plate, respectively. The support plate 06 has through holes. Two handle nuts 08 are respectively confined in the through holes on the support plate 06 and can rotate freely. Their lower ends are threadedly engaged with the slider 04, converting the rotation of the handle nuts 08 into the up and down movement of the slider 04. The slider 04 has a vertical strip groove, which cooperates with the guide post on the cover plate 09 to achieve motion guidance. In use, the die-type jig is placed on the base plate of the clamping body 07 and close to the L-shaped upright plate. The lower ends of the two sliders 04 abut against the top surface of the die-type jig to fix the die-type jig.

[0009] A method for rapid compression molding of a jig-type tire includes the following steps:

[0010] Step 1: Insert the drill bit to be press-fitted into the mandrel 01, and then fasten it to the press-fit guide post 02 by locking the cross pin 03.

[0011] Step 2: Place the die-type jig on the base plate of the fixture 07 and ensure it is in close contact with the L-shaped vertical plate of the fixture 07, ensuring no gaps; adjust the two handle nuts 08 to move the two sliders 04 down and press the die-type jig together.

[0012] Step 3: Align the mandrel 01 with the drill bushing hole in the die-type tire, ensuring that the guide post 02 is axially perpendicular, and tap the guide post 02 until the drill bushing is pressed into the die-type tire; the die-type tire pressing is now complete.

[0013] The beneficial effects of this invention are as follows:

[0014] This invention enables the pressing of all drill bushings into a jig-type mold with a single strike, improving pressing efficiency. Furthermore, the guide mandrel design effectively prevents axial deviations after pressing, thus improving pressing accuracy. The design of this rapid pressing device with a jig-type mold eliminates the need to process multiple drill bushings as spares, saving labor, materials, and time costs. Attached Figure Description
