Description

Technical Field

[0001] This utility model belongs to the field of mechanical tooling and relates to a precision connection platform for a power transmission device used in flexible assembly. Background Technology

[0002] The existing method of connecting integrated power transmission devices involves fixing the engine to a bracket, then horizontally lifting the integrated transmission device. The operator uses a pry bar to adjust the angle of the engine output end gear sleeve and directs the crane to raise and lower to adjust the height of the integrated transmission device so as to align the input end gear of the integrated transmission device with the output end gear sleeve of the engine. The device is then positioned using locating pins, and the engine and integrated transmission device are connected and tightened with bolts.

[0003] The connection process using a crane is greatly affected by human factors, is difficult to observe, cannot be accurately connected by measurement, has low work efficiency, is prone to collisions and damage to the mating surfaces of parts, creating potential quality hazards, and requires personnel to work under the crane for extended periods, and to "level" the connection by swaying the slings and the integrated transmission device, posing significant safety risks. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a flexible assembly power transmission device connection platform. The engine is placed on an engine mounting platform, and the integrated transmission device is then placed on an integrated transmission device mounting platform. A process gear is installed on the engine output end gear sleeve. Using a lead screw and slide rail, the integrated transmission device is brought close to the engine. The teeth of the integrated transmission device input end gear and the process gear are then observed to ensure complete correspondence. If they are not completely aligned, their horizontal and vertical distances are measured, and the height difference is compensated by adjusting a linked ball screw jack. The position of the integrated transmission device in the X direction is adjusted by sliding a lateral moving platform along the X direction, ensuring complete engagement of the teeth of the integrated transmission device input end gear sleeve and the process gear. The integrated transmission device and the engine are connected by sliding a longitudinal slide rail along the Y direction and secured with bolts. This improves work efficiency and enhances the inherent safety of the equipment.

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

[0006] A power transmission device precision connection platform for flexible assembly, the connection platform includes an engine fixing platform (1), an integrated transmission device fixing platform (2), and a connection reference workbench (3);

[0007] The engine fixed platform (1) and the integrated transmission device fixed platform (2) are both arranged axially on the connecting reference worktable (3). The position of the engine fixed platform (1) is fixed, while the integrated transmission device fixed platform (2) can move along the X, Y and Z directions.

[0008] Furthermore, the engine mounting platform (1) includes a support leg (4), an engine support platform (5), and an engine support seat (6). The support leg (4) is fixedly connected to the engine support platform (5) located above it, and the engine support seat (6) is connected and fastened to the engine support platform (5) located below it. The engine is fixed on the engine support seat (6).

[0009] Furthermore, the support leg (4) and the engine support platform (5) are fixedly connected by bolts.

[0010] Furthermore, the engine support base (6) and the engine support platform (5) are fastened together by bolts.

[0011] Furthermore, the engine support platform 5 is marked with the fixed positions of the engine support seats for different products, and holes are made there.

[0012] Furthermore, each product's engine support mount is equipped with several adjusting shims ranging in thickness from 0.02mm to 2mm for engine leveling.

[0013] Furthermore, the fixed platform (2) of the integrated transmission device includes a screw device (7), a longitudinal slide rail (8), a slide rail conversion table (9), a ball screw device (10), a transverse moving platform (11), a linkage ball screw lift (12), an integrated transmission device support platform (13), and an integrated transmission device support ring (14).

[0014] The longitudinal slide rail (8) is located on the upper surface of the connecting reference worktable (3) and fixed. The slide rail conversion table (9) is located on the longitudinal slide rail (8) and can move along its longitudinal direction. The screw device (7) is fixed to the lower surface of the slide rail conversion table (9) and the slide rail conversion table (9) moves along the longitudinal slide rail (8) through the screw device (7). The upper surface of the slide rail conversion table (9) is connected to the ball screw device (10). The lower surface of the transverse moving platform (11) is connected to the ball screw device (10). A linkage ball screw jack (12) is fixed at each of the four corners of the upper surface of the transverse moving platform (11). A comprehensive transmission device support platform (13) is fixed above the linkage ball screw jack (12). A comprehensive transmission device support ring (14) is installed above the comprehensive transmission device support platform (13). The comprehensive transmission device angle adjustment mechanism (17) is installed above the comprehensive transmission device support platform (13) and connected to the comprehensive transmission device support ring (14) located on one side of it.

[0015] Furthermore, manually cranking the handwheel causes the ball screw device 10 to move the transverse moving platform 11 0.02mm along the Y direction for every 1 degree of rotation; manually cranking the handwheel also causes the linkage ball screw lifting machine 12 to raise or lower the integrated transmission device support platform 13 0.02mm for every 1 degree of rotation.

[0016] Furthermore, each product is equipped with a corresponding integrated transmission device support ring 14, and several adjusting shims with a thickness of 0.02mm to 2mm for leveling the integrated transmission device.

[0017] Further, after the engine and integrated transmission are leveled, the angle of the integrated transmission is adjusted by the angle adjustment mechanism to make the engine and integrated transmission parallel. The process gear is installed at the output end of the engine, and the process gear sleeve is installed at the input end of the integrated transmission. The motor drives the ball screw device 10 to move the slide rail conversion table 9 on the longitudinal slide rail, so that the integrated transmission gradually approaches the engine. When the process gear and the gear sleeve just make contact, the motor is turned off. The coaxiality of the process gear and the process gear sleeve is measured. By adjusting the ball screw device 10 and the linkage ball screw lift 12, the coaxiality is made less than or equal to 0.04. The process gear and the process gear sleeve are disassembled, the motor is started, and the connection between the engine and the integrated transmission is completed.

[0018] The advantages of this utility model:

[0019] This invention installs a process gear at the engine output end and a process sleeve at the input end of the integrated transmission device. The two parts to be connected are then "drawn out," their coaxiality is measured, and then the height, left-right, and front-back positions of the integrated transmission device are adjusted using a lead screw device, ball screw device, linked ball screw jack, and slide rails. This achieves a precise connection between the engine and the integrated transmission device. Previously, adjusting the height, left-right, and front-back positions while the integrated transmission device was suspended was necessary for connection, which easily caused bumps and damage to the mating surfaces of the parts, creating potential quality issues. Furthermore, personnel working under a crane for extended periods and having to use slings to sway the integrated transmission device to "level" it posed significant safety hazards. Therefore, this invention changes the traditional connection process, offering advantages such as avoiding surface damage to the product, eliminating safety hazards during lifting operations, and improving work efficiency.

The position of the engine fixing platform (1) is fixed, and the integrated transmission device fixing platform (2) can move along the X, Y, and Z directions.

[0027] Working principle:

[0028] The motor-driven lead screw device drives the fixed platform of the integrated transmission device to move axially. Check the coaxiality of the input gear of the integrated transmission device and the output gear sleeve of the engine. If they are not coaxial, adjust the linkage ball screw jack to compensate for the height difference. Adjust the position of the integrated transmission device in the X direction by sliding the transverse moving platform along the X direction to make the input gear of the integrated transmission device and the output gear sleeve of the engine coaxial. Connect the integrated transmission device and the engine by sliding the longitudinal slide rail along the Y direction and tighten it with bolts to improve work efficiency and enhance the inherent safety of the equipment.

[0029] like Figure 2 As shown, the engine mounting platform (1) is mainly composed of support legs (4), engine support platform (5), and engine support seat (6). The support legs (4) are fixedly connected to the engine support platform (5) located above them by bolts, and the engine support seat (6) is fixedly connected to the engine support platform (5) located below them by bolts. The engine is fixed on the engine support seat (6).

[0030] Working principle:

[0031] Each product is equipped with a corresponding engine support base. The fixed positions of the engine support bases for different products are marked on the engine support platform 5, and holes are drilled for bolt connection and fastening. Each product's engine support base is equipped with several adjustment shims with a thickness ranging from 0.02mm to 2mm for engine leveling.

[0032] like Figure 3 As shown, the fixed platform (2) of the integrated transmission device is mainly composed of a screw device (7), a longitudinal slide rail (8), a slide rail conversion table (9), a ball screw device (10) (with an operating handwheel), a transverse moving platform (11), a linkage ball screw lift (12) (with an operating handwheel), an integrated transmission device support platform (13), and an integrated transmission device support ring (14).

[0033] The longitudinal slide rail (8) is located on the upper surface of the connecting reference worktable (3) and is fixedly connected by bolts. The slide rail conversion table (9) is located on the longitudinal slide rail (8) and can move longitudinally along it. The screw device (7) is fixed to the lower surface of the slide rail conversion table (9) and the slide rail conversion table (9) moves longitudinally along the longitudinal slide rail (8) through the screw device (7). The upper surface of the slide rail conversion table (9) is connected to the ball screw device (10), and the lower surface of the transverse moving platform (11) is connected to the ball screw device (10). One linkage ball screw jack (12) is fixed at each of the four corners of the upper surface of the transverse moving platform (11). The integrated transmission device support platform (13) is fixed above the linkage ball screw jack (12), and the integrated transmission device support ring (14) is installed above the integrated transmission device support platform (13). The integrated transmission device angle adjustment mechanism (17) is installed above the integrated transmission device support platform (13) and connected to the integrated transmission device support ring (14) located on one side of it. The integrated transmission device support ring (14) and the integrated transmission device support platform (13) are connected by bolts. The integrated transmission device support ring (14) and the integrated transmission device angle adjustment mechanism (17) are connected by a lead screw drive.

[0034] The process of using the power transmission device connection platform for flexible assembly is as follows:

[0038] (2) The fixed platform of the integrated transmission device is adjusted along the axis, front and back, and height.

[0039] 1) The motor drives the lead screw device (7), which drives the longitudinal slide rail (8) to move axially. After the longitudinal slide rail (8) approaches the engine fixed platform (1), the lead screw device is switched to manual mode. The handwheel is manually turned. For every 1 degree of rotation of the handwheel, the longitudinal slide rail (8) moves 0.5 mm axially.

[0040] 2) Manually crank the handwheel to drive the ball screw device (10), which in turn drives the transverse moving platform (11) to move back and forth. For every 1 degree the handwheel rotates, the transverse moving platform (11) moves back and forth by 0.02 mm.

[0041] 3) Manually crank the handwheel to drive the linkage ball screw jack (12), which in turn moves the integrated transmission device support platform (13) 0.02mm in the vertical direction;

[0042] (3) Connection between engine and integrated transmission

[0043] 1) Position the engine and the integrated transmission unit close to the appropriate location, install the process gear (15) at the engine output end, and install the process gear sleeve (16) at the integrated transmission unit input end;

[0044] 2) such as Figure 1 , Figure 4 As shown, after the engine and the integrated transmission device are leveled, the angle of the integrated transmission device is adjusted by the integrated transmission device angle adjustment mechanism so that the end face of the process gear (15) and the end face of the process gear sleeve (16) are parallel.

[0045] 3) Use a laser alignment instrument to measure the coaxiality of the process gear (15) and the process sleeve (16);

[0046] 4) Based on the measurement results, manually crank the handwheel to drive the ball screw jack (12) to adjust the front and rear position of the integrated transmission device; manually crank the handwheel to drive the linkage ball screw jack (12) to adjust the height position of the integrated transmission device; so that the coaxiality of the process gear (15) and the process sleeve (16) is less than 0.04.

[0047] 5) Remove the process gear (15) and process gear sleeve (16);

[0048] 6) Crank the handwheel to drive the lead screw device (7) so that the integrated transmission device moves axially and completes the connection between the engine and the integrated transmission device.

[0050] 1. Check the coaxiality of the process gear installed at the engine output end and the process gear sleeve installed at the input end of the integrated transmission device, and then adjust them to achieve a precise connection between the engine and the integrated transmission device.
