Abstract

This application belongs to the field of industrial auxiliary equipment, and specifically relates to a tooling trolley device for rotating shell workpieces. The device connects and fixes a fixed rod, a rotating seat, and a right-angle seat using quick-release pins. Based on the dimensions of the rotating shell workpiece, the flange size is replaced with a suitable size. The tooling trolley is pushed outdoors, and the length of the extended screw is adjusted by turning the screw nut, thereby adjusting the trolley height. After adjustment, once the height is determined, the flange is moved to the appropriate position via a sprocket drive assembly and a screw drive assembly. The trolley frame is then inserted under a transfer trolley carrying the rotating shell workpiece, and the rotating shell workpiece is aligned with the flange and clamped. Finally, a worker pushes the handle to transfer the tooling trolley along with the rotating shell workpiece. This solves the problem in existing technologies where the inability to adjust the workpiece height leads to a lack of quick docking between the tooling trolley device and the transfer trolley, thus better ensuring the safety of both the workpiece and the worker.

Description

Technical Field

[0001] This application belongs to the field of industrial auxiliary equipment, and specifically relates to a tooling carriage device for rotating shell workpieces. Background Technology

[0002] When performing automated repair painting on rotating shell workpieces, such as aircraft radomes, it is necessary to install them from a transport vehicle to a tooling vehicle outdoors. The height of the transport vehicle for rotating shell workpieces is fixed. In existing technologies, the tooling vehicle for rotating shell workpieces generally does not have a height adjustment function, and if the heights of the tooling vehicle and the transport vehicle are different, they cannot be docked. After the automated painting is completed, the rotating shell workpieces need to be transferred to a drying room for drying, which also requires the realization of a rapid transfer function for rotating shell workpieces.

[0003] An existing workpiece-specific tooling carriage consists of a movable base plate, a support plate, an adjusting plate, a support rod, a rotating wheel, an adjusting rod, a connecting rod, and a fixed seat. The height of the adjusting plate can be adjusted by rotating the wheel, thereby adjusting the installation range of the workpiece size.

[0004] The above design cannot achieve the functions of adjusting the workpiece height and quickly docking the tooling carriage with the transfer carriage. Utility Model Content

[0005] The purpose of this application is to provide a tooling carriage device for rotating shell workpieces, so as to solve the problem that the existing design cannot realize the adjustment of workpiece height and the quick docking function between the tooling carriage device and the transfer car.

[0006] The technical solution of this application is: a tooling carriage device for a rotating shell workpiece, comprising a frame, a tooling fixture, and a rotating shell; the tooling fixture is mounted on the frame, and the rotating shell is mounted on the tooling fixture; the tooling fixture includes a movable flap, the frame includes a frame body, an extended lead screw, and a limiting assembly; the frame body is placed horizontally on the ground, and handrails are symmetrically connected to both sides of the frame body; the movable flap is located on the frame body, one end of the limiting assembly is hinged to the side wall of the movable flap, and the other end is hinged to the top of the frame body; the extended lead screw is threadedly connected to the frame body, and a lead screw nut is threadedly connected to the upper end of the extended lead screw, and a caster wheel is threadedly connected to the lower end of the extended lead screw.

[0007] Preferably, there are two sets of limiting components symmetrically arranged on both sides of the movable flap. Each limiting component includes a fixed rod and a rotating seat. A right-angle seat is provided on the side wall of the movable flap. The rotating seat is fixedly connected to the top of the frame body. One end of the fixed rod is connected to the right-angle seat by a pin, and the other end is hinged to the rotating seat.

[0008] Preferably, the tooling fixture further includes a flange, a sprocket drive assembly, a lead screw drive assembly, and a lead screw nut pair; the flange is disposed on the lead screw drive assembly, the lead screw drive assembly is disposed on the movable flap, the sprocket drive assembly is disposed at one end of the movable flap and connected to the lead screw drive assembly; a lead screw slider drive mechanism is disposed inside the lead screw drive assembly; a sprocket chain drive mechanism is disposed inside the sprocket drive assembly and connected to the slider of the lead screw drive assembly; the lead screw nut pair is threadedly connected between the movable flap and the frame body.

[0009] The tooling trolley device for rotating shell workpieces disclosed in this application involves first connecting and securing the fixed rod, rotating seat, and right-angle seat using quick-release pins. Based on the dimensions of the rotating shell workpiece, the flange size is replaced with a suitable one. The entire tooling trolley is then pushed outdoors. The length of the extended screw is adjusted by turning the screw nut, thereby adjusting the trolley height. After adjustment, once the height is determined, the flange is moved to the appropriate position via the sprocket drive assembly and screw drive assembly. The trolley frame is then inserted under the transfer trolley carrying the rotating shell workpiece. The rotating shell workpiece is aligned with the flange and clamped, secured from the outside using hook bolts. After installation, the nuts behind the hook bolts are tightened. Finally, a worker pushes the handle to transfer the tooling trolley along with the rotating shell workpiece. This solves the problem in existing technologies where the inability to adjust the workpiece height leads to slow docking between the tooling trolley device and the transfer trolley, thus better ensuring the safety of both the workpiece and the worker.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] A tooling carriage for a rotating shell workpiece, such as Figure 1 As shown, it includes a frame, a tooling fixture, and a rotating housing. The tooling fixture is mounted on the frame, and the rotating housing is mounted on the tooling fixture.

[0015] The fixture includes a movable flap 5, and the frame includes a frame body 1, an extended screw 12, and a limiting assembly. The frame body 1 is placed horizontally on the ground, with handlebars 2 symmetrically connected to both sides. The movable flap 5 is located on the frame body 1. One end of the limiting assembly is hinged to the side wall of the movable flap 5, and the other end is hinged to the top of the frame body 1, so that the frame body 1 can support the movable flap 5 through the limiting assembly when it is flipped. The extended screw 12 is threaded onto the frame body 1, with a screw nut 11 threaded to the upper end and a caster wheel 4 threaded to the lower end. By rotating the extended screw 12, the height of the frame can be adjusted, thereby changing the height difference between the frame and the movable flap 5.

[0016] Preferably, there are two sets of limiting components symmetrically arranged on both sides of the movable flap 5. The limiting components include a fixing rod 13 and a rotating seat 14. A right-angle seat is provided on the side wall of the movable flap 5. The rotating seat 14 is fixedly connected to the top of the frame body 1. One end of the fixing rod 13 is connected to the right-angle seat by a pin, and the other end is hinged to the rotating seat 14. Before the movable flap 5 is flipped, the pin is removed; after the movable flap 5 is flipped, the pin is inserted between the right-angle seat and the fixing rod 13 to fix it.

[0017] Preferably, the tooling fixture further includes a flange 3, a sprocket drive assembly 7, a lead screw drive assembly 8, and a lead screw and nut pair 6. The flange 3 is mounted on the lead screw drive assembly 8, which is mounted on the movable flap 5. The sprocket drive assembly 7 is located at one end of the movable flap 5 and connected to the lead screw drive assembly 8. The lead screw drive assembly 8 internally incorporates a lead screw-slider drive mechanism, which uses a conventional design and will not be described in detail. The sprocket drive assembly 7 internally incorporates a sprocket and chain drive mechanism, which is connected to the slider of the lead screw drive assembly 8, also using a conventional design and will not be described in detail. The flange 3 can move horizontally along the direction of the lead screw under its drive.

[0018] The lead screw and nut assembly 6 is threadedly connected between the movable flap 5 and the frame body 1. By rotating the lead screw in the lead screw and nut assembly 6, the height of the movable flap 5 can be adjusted, thereby ensuring that the height difference between the frame body 1 and the movable flap 5 is appropriate.

[0019] In use, first, connect and fix the fixed rod 13, rotating seat 14, and right-angle seat using quick-release pins. Replace the flange 3 with a suitable size according to the dimensions of the rotating shell workpiece. Push the entire tooling cart outdoors. Adjust the length of the extended screw 12 by turning the screw nut 11, thereby adjusting the height of the cart frame. After adjustment, once the height is determined, move the flange 3 to the appropriate position using the sprocket drive assembly 7 and screw drive assembly 8. Then, insert the cart frame under the transfer cart with the rotating shell workpiece, align the rotating shell workpiece with the flange 3, and clamp it. Secure it from the outside of the flange 3 using hook bolts. After installation, tighten the nuts behind the hook bolts. Finally, the worker pushes the handle 2 to transfer the tooling cart along with the rotating shell workpiece. This solves the problem in existing technologies where the inability to adjust the workpiece height leads to slow docking between the tooling cart and the transfer cart, better ensuring the safety of both the workpiece and the worker.
