Description

Technical Field

[0001] This utility model relates to the technical field of five-axis turntable components, and in particular to a five-axis turntable component assembly table. Background Technology

[0002] A five-axis rotary table is a type of CNC rotary table and a commonly used component in machine tool processing. The axis that rotates around the X-axis is defined as the A-axis, and the axis that rotates around the Z-axis is defined as the C-axis. The five-axis cradle rotary table can meet the processing requirements of the workpiece fixed on the output flange by combining the A-axis and C-axis.

[0003] The existing five-axis rotary table has a complex structure, requiring the assembly of multiple large and precision components (such as the base, rotary table, oscillating heads of each axis, drive units, etc.) in a strict order and with high precision requirements to finally form a complete rotary table. However, the current assembly process is highly dependent on manual operation, which presents a significant bottleneck.

[0004] Specifically, during the assembly process, hoisting equipment (such as overhead cranes and electric hoists) is commonly used to transport heavy parts one by one to a simple assembly platform or work area. The key pain point is that after the parts are suspended in the air, in order to meet the requirements of subsequent connection, hole alignment, or positioning, operators often need to repeatedly and laboriously manually adjust the posture and angle of the parts in the air. For example, a large bearing seat needs to be tilted at a specific angle to accurately mate with the base below, or the oscillating head assembly needs to be rotated to a precise position to install the drive motor and cables. This angle adjustment process has several serious problems:

[0005] Difficult to fix precisely: Manual operation lacks reliable auxiliary positioning devices, and adjustments are made solely based on experience and feel. Parts are prone to swaying in the air due to gravity and cable tension. Even if they are adjusted to close to the required angle, it is extremely difficult to maintain stability without external support. Workers may need to try multiple times, or even require additional personnel for support or fine-tuning.

[0006] Time-consuming and labor-intensive: Each angle adjustment is a delicate and time-consuming process that requires workers to concentrate highly, operate the lifting equipment carefully, and manually apply push / pull forces. For large and heavy parts, this process is particularly strenuous and slow.

[0007] Impact on assembly accuracy: The instability and difficulty in precisely fixing angle adjustments directly lead to the relative positions and orientations of components failing to meet the accuracy requirements of the design drawings. Even minor angular deviations can be amplified in subsequent assembly steps, potentially causing interference, excessively tight or loose fits, or even requiring rework and reassembly.

[0008] Reduced overall efficiency: Repeated and inefficient angle adjustment operations, and the resulting precision problems and rework, significantly slow down the assembly rhythm of the entire five-axis rotary table component. The "bottleneck time" of each part assembly is lengthened, resulting in low overall assembly line efficiency and limited production capacity.

[0009] Increased safety risks: Frequent manual operation of heavy suspension components for angle adjustment also increases the risk of operational errors, accidental slippage or collision of parts, posing a potential threat to the safety of workers and equipment. Utility Model Content

[0010] Based on the existing primitive assembly method that relies on manual hoisting and aerial attitude adjustment, the inefficiency, instability and difficulty in fixing the angle adjustment process have become a key technical obstacle restricting the assembly quality, production efficiency and operation safety of five-axis turntable components. This utility model proposes a five-axis turntable component assembly platform.

[0011] This utility model proposes a five-axis rotary table assembly platform, including an assembly frame. The outer surface of the assembly frame is rotatably connected to a turntable with a worm gear via bearings. The outer surface of the assembly frame is also rotatably connected to a handle with a worm, and the worm of the handle meshes with the worm gear of the turntable.

[0012] The assembly frame is equipped with an adjustment device and a support device. The adjustment device includes an adjustment screw, and the rotation of the adjustment screw adjusts the position of the support device.

[0013] The support device is located on the outer surface of the adjustment device, and the support device includes a set of support rollers, which supports the shaftless turntable component that is being assembled on the assembly frame.

[0014] Preferably, the adjustment device further includes a drive motor, which is fixedly installed on the inner wall of the assembly frame. The two ends of the adjustment screw are rotatably connected to the inner wall of the assembly frame through bearings. One end of the output shaft of the drive motor is fixedly installed to one end of the adjustment screw through a coupling. A limit rod is fixedly installed on the inner wall of the assembly frame.

[0015] Preferably, the outer surface of the adjusting screw is threadedly connected to an adjusting frame, one end of the adjusting frame is slidably sleeved with the outer surface of the limiting rod, the outer surface of the adjusting frame is hinged to an adjusting electric cylinder via a pin, a deflection gear is fixedly installed on the outer surface of the pin of the adjusting electric cylinder, and a deflection rack is fixedly installed on the inner wall of the assembly frame, the deflection gear meshing with the deflection rack.

[0016] Preferably, a mounting bracket is fixedly installed on the outer surface of the pin of the adjusting electric cylinder, a ball bearing is rotatably connected to the inner wall of the mounting bracket, a limit strip is fixedly installed on the inner wall of the assembly bracket, and the outer surface of the ball bearing is slidably connected to the outer surface of the limit strip.

[0017] Preferably, the support device further includes a support plate, which is fixedly installed at one end of the piston rod of the adjusting electric cylinder. A limit sleeve is fixedly installed on the outer surface of the support plate, and the inner wall of the limit sleeve is slidably inserted into one end of the support roller assembly.

[0018] Preferably, a support shell is fixedly installed on the outer surface of the support plate, a fixing sleeve is fixedly installed on the inner wall of the support shell, a fine-tuning airbag is fixedly installed on the inner wall of the fixing sleeve, one end of the support roller assembly is slidably connected to the inner wall of the fixing sleeve and then fixedly installed to one end of the fine-tuning airbag, a return spring is fixedly installed on the inner wall of the support shell, and one end of the return spring is fixedly installed to the outer surface of the support roller assembly.

[0019] Preferably, the outer surface of the fine-tuning airbag is fixedly connected to a delivery branch pipe with a control valve, the outer surface of the delivery branch pipe is connected to the outer surface of the supporting shell, the outer surface of the fine-tuning airbag is fixedly connected to an air outlet control valve through a pipe, one end of the air outlet control valve is fixedly installed to the outer surface of the fixed sleeve, an air pump is fixedly installed on the inner wall of the assembly frame, the air inlet of the air pump is fixedly connected to a connecting hose, one end of the connecting hose is fixedly connected to one end of the delivery branch pipe, and the outer surface of the connecting hose is fixedly installed to the outer surface of the adjustment frame.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. By setting an adjustment device, the support device can be stored, so that the support device does not occupy the space of the assembly rack when not in use. The adjustment frame can be moved by rotating the adjustment screw. After the deflection gear on the adjustment electric cylinder meshes with the deflection rack, the adjustment electric cylinder is flipped from a horizontal state to a vertical state, which facilitates the support of the five-axis turntable components. The state of the adjustment electric cylinder can be supported by the insertion between the ball bearings and the limit strip on the mounting frame.

[0022] 2. By setting up a support device, the five-axis turntable component can be supported. Turning the handle can drive the turntable to rotate. The base of the five-axis turntable component is fixedly installed with the turntable, thereby allowing adjustment of the installation angle, which facilitates the installation of subsequent parts. By adjusting the electric cylinder, the support plate is pushed close to the five-axis turntable component. After the support roller group contacts the five-axis turntable component, it supports the five-axis turntable component. By supplying gas to the fine-tuning airbag, the fine-tuning airbag expands and supports the five-axis turntable component. At the same time, it facilitates the support roller group to fit against the outer surface of the shaftless turntable component, thus facilitating stable installation. This solves the technical problem of the existing primitive assembly method that relies on manual hoisting and aerial attitude adjustment. Due to the inefficiency, instability and difficulty in fixing the angle adjustment link, it has become a key obstacle restricting the assembly quality, production efficiency and operation safety of the five-axis turntable component.

[0032] 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.

[0033] Reference Figures 1-8 A five-axis turntable assembly platform includes an assembly frame 1, a door panel is hinged to the assembly frame 1, a turntable 11 with a worm gear is rotatably connected to the outer surface of the assembly frame 1 via a bearing, and a handle 12 with a worm is rotatably connected to the outer surface of the assembly frame 1, the worm of the handle 12 meshing with the worm gear of the turntable 11.

[0034] The assembly frame 1 is equipped with an adjustment device and a support device. The adjustment device includes an adjustment screw 21, and the rotation of the adjustment screw 21 adjusts the position of the support device.

[0035] Specifically, in order to automatically adjust the position of the support device, the adjustment device also includes a drive motor 2, which is fixedly installed on the inner wall of the assembly frame 1. The two ends of the adjusting screw 21 are rotatably connected to the inner wall of the assembly frame 1 through bearings. One end of the output shaft of the drive motor 2 is fixedly installed to one end of the adjusting screw 21 through a coupling. The threads at both ends of the adjusting screw 21 are symmetrically distributed. A limit rod 22 is fixedly installed on the inner wall of the assembly frame 1.

[0036] Specifically, an adjusting frame 23 is threadedly connected to the outer surface of the adjusting screw 21. One end of the adjusting frame 23 is slidably sleeved with the outer surface of the limiting rod 22. An adjusting electric cylinder 24 is hinged to the outer surface of the adjusting frame 23 via a pin. The adjusting electric cylinder 24 is an electro-hydraulic cylinder. A deflection gear 25 is fixedly installed on the outer surface of the pin of the adjusting electric cylinder 24. A deflection rack 26 is fixedly installed on the inner wall of the mounting frame 1. The deflection gear 25 meshes with the deflection rack 26. By moving the adjusting frame 23, the deflection gear 25 can mesh with the deflection rack 26, thereby driving the adjusting electric cylinder 24 to rotate.

[0037] Specifically, in order to facilitate the stabilization of the electric adjustment cylinder 24 after steering, a mounting bracket 3 is fixedly installed on the outer surface of the pin of the electric adjustment cylinder 24. A ball bearing 31 is rotatably connected to the inner wall of the mounting bracket 3. A limit strip 32 is fixedly installed on the inner wall of the assembly frame 1. The outer surface of the ball bearing 31 is slidably connected to the outer surface of the limit strip 32.

[0038] By setting an adjustment device, the support device can be stored, so that the support device does not occupy the space of the assembly frame 1 when it is not in use. The rotation of the adjustment screw 21 can drive the adjustment frame 23 to move. After the deflection gear 25 on the adjustment electric cylinder 24 meshes with the deflection rack 26, the adjustment electric cylinder 24 is flipped from a horizontal state to a vertical state, which facilitates the support of the five-axis turntable component. The state of the adjustment electric cylinder 24 can be supported by the insertion between the ball bearing 31 on the mounting frame 3 and the limit bar 32.

[0039] To support the base of the five-axis turntable, a support device is located on the outer surface of the adjustment device. The support device includes a support roller assembly 42, which supports the shaftless turntable component assembled on the assembly frame 1. To better adjust the support force, a pressure sensor can be installed inside the support roller assembly 42. The pressure sensor can detect the pressure on the support roller assembly 42, thereby enabling precise adjustment of the position of the support roller assembly 42. In the absence of a pressure sensor, the support roller assembly 42 can be manually observed to determine whether it is in contact with the base.

[0040] Specifically, the support device also includes a support plate 4, which is fixedly installed at one end of the piston rod of the adjusting electric cylinder 24. In order to limit the support roller assembly 42, a limiting sleeve 41 is fixedly installed on the outer surface of the support plate 4. The inner wall of the limiting sleeve 41 is slidably inserted into one end of the support roller assembly 42. The support roller assembly 42 is composed of rollers and a bracket, and the rollers are rotatably connected to the bracket.

[0041] Specifically, in order to fine-tune the position of the support roller assembly 42, a support housing 43 is fixedly installed on the outer surface of the support plate 4, a fixing sleeve 44 is fixedly installed on the inner wall of the support housing 43, a fine-tuning airbag 45 is fixedly installed on the inner wall of the fixing sleeve 44, one end of the support roller assembly 42 is slidably connected to the inner wall of the fixing sleeve 44 and then fixedly installed on one end of the fine-tuning airbag 45. In order to facilitate the reset of the support roller assembly 42, a reset spring 46 is fixedly installed on the inner wall of the support housing 43, and one end of the reset spring 46 is fixedly installed on the outer surface of the support roller assembly 42.

[0042] Specifically, in order to deliver gas into the fine-tuning airbag 45, a delivery pipe 5 with a control valve is fixedly connected to the outer surface of the fine-tuning airbag 45. The control valve is an SMC solenoid valve, model VQ5251-5HB. The outer surface of the delivery pipe 5 is connected to the outer surface of the supporting shell 43. In order to facilitate the gas discharge from the fine-tuning airbag 45, an exhaust control valve 51 is fixedly connected to the outer surface of the fixed sleeve 44 through a pipe. One end of the exhaust control valve 51 is fixedly installed to the outer surface of the fixed sleeve 44. The exhaust control valve 51 is an SMC solenoid valve, model VQ5251-5HB. An air pump 52 is fixedly installed on the inner wall of the assembly frame 1. The air inlet end of the air pump 52 is fixedly connected to a connecting hose 53. One end of the connecting hose 53 is fixedly connected to one end of the delivery pipe 5. The outer surface of the connecting hose 53 is fixedly installed to the outer surface of the adjusting frame 23.

[0043] By setting up a support device, the five-axis turntable component can be supported. Rotating the handle 12 can drive the turntable 11 to rotate. The base of the five-axis turntable component is fixedly installed with the turntable 11, thereby allowing the installation angle to be adjusted, which facilitates the installation of subsequent parts. By adjusting the electric cylinder 24, the support plate 4 is pushed close to the five-axis turntable component. After the support roller assembly 42 contacts the five-axis turntable component, it supports the five-axis turntable component. By supplying gas to the fine-tuning airbag 45, the fine-tuning airbag 45 expands and supports the five-axis turntable component. At the same time, it facilitates the support roller assembly 42 to fit against the outer surface of the shaftless turntable component, thereby facilitating stable installation. This solves the technical problem of the existing primitive assembly method that relies on manual hoisting and aerial attitude adjustment. Due to the inefficiency, instability and difficulty in fixing the angle adjustment link, it has become a key obstacle restricting the assembly quality, production efficiency and operation safety of the five-axis turntable component.

[0044] The power supply structure involved can be powered by connecting a plug to the assembly frame or by installing a battery inside, which is existing technology.

[0045] Working principle: By installing the five-axis turntable base on the turntable 11 and opening the door panel, the support and adjustment devices can be easily operated. The drive motor 2 is started, which drives the adjusting screw 21 to rotate. The adjusting screw 21 can drive the adjusting frame 23 to move. After the deflection gear 25 of the adjusting electric cylinder 24 on the adjusting frame 23 meshes with the deflection rack 26, the adjusting electric cylinder 24 deflects as the adjusting frame 23 moves. After changing from a horizontal state to a vertical mounting frame 1 state, the mounting frame 3 moves and inserts into the limiting bar 32. The ball bearing 31 rolls on the upper and lower surfaces of the limiting bar 32, and the adjusting electric cylinder 24 moves to the set position that needs to be supported.

[0046] The electric cylinder 24 pushes the support plate 4 to rise, so that the support roller assembly 42 contacts the lower surface of the five-axis turntable base. When the lower surface of the five-axis turntable base is uneven, or when the five-axis turntable base needs to be deflected when installing other parts, the air pump 52 is turned on to draw air into the connecting hose 53. After the air enters the delivery pipe 5 through the connecting hose 53, the corresponding solenoid valve is turned on and the gas enters the fine-tuning airbag 45. After the fine-tuning airbag 45 expands, it pushes the support roller assembly 42 to move. The support roller assembly 42 moves within the limit sleeve 41 and contacts the five-axis turntable base to support it. When the shaftless turntable base needs to be adjusted, the gas in the fine-tuning airbags 45 on both sides is opened through the gas outlet control valve 51 and the gas flows out. Under the elastic force of the return spring 46, the fine-tuning airbag 45 drives the support roller assembly 42 to return to its original position. The middle support roller assembly 42 supports the five-axis turntable base, which facilitates the deflection of the base.

[0047] When the angle of the base needs to be adjusted, the handle 12 is rotated, and the worm gear of the handle 12 drives the worm wheel of the turntable 11 to rotate, thereby driving the fixed base to adjust the angle.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
