A rotating mechanism is installed at the upper end of one side of the tooling base 1, and the output end of the rotating mechanism is hinged to one end of the rotating pallet 2. The upper end of the tooling base 1 is slidably connected to the support 3. The support 3 is used to support the lower end surface of the rotating pallet 2 and is in line contact or point contact with the lower end surface of the rotating pallet 2, and the support 3 is connected to the telescopic mechanism. The telescopic mechanism is used to drive the support 3 to move closer to or away from the rotating mechanism. The rotating mechanism is used to drive the rotating pallet 2 to rotate around the rotating mechanism within the range of line contact or point contact between the rotating pallet 2 and the support 3. The upper end of the rotating pallet 2 is used to install the product to be assembled.

[0022] The present invention can install the product to be assembled on the upper end of the rotating pallet 2 through the coordinated arrangement of the tooling base 1, the rotating support plate 2, the support 3, the telescopic mechanism and the rotating mechanism, and use the telescopic mechanism to drive the support 3 to move closer to or away from the rotating mechanism, thereby realizing the driving of the rotating pallet 2 to rotate around the hinge with the rotating mechanism, and thereby realizing the function of adjusting the use angle of the rotating pallet 2 to adjust the assembly angle of the product to be assembled; through the connection between the end of the rotating pallet 2 and the rotating mechanism, and the linear contact or point contact between the rotating pallet 2 and the upper end of the support 3, the rotating pallet 2 can be rotated as needed. The driving mechanism drives the rotating pallet 2 to rotate around the rotating mechanism within the range of line contact or point contact between the rotating pallet 2 and the support 3, thereby conveniently fine-tuning the use direction of the rotating pallet 2 to adjust the assembly direction of the product to be assembled; at the same time, during the rotation of the rotating pallet 2, the support 3 is in line contact or point contact with the rotating pallet 2, and will not interfere with the rotation of the rotating pallet 2. In this way, the problem of inconvenient alignment and positioning when assembling heavy parts can be solved and the adjustment effect can be guaranteed, and the influence of adjustment accuracy caused by mutual interference between structures can be avoided.

[0023] In this embodiment, the telescopic mechanism can adopt an electric telescopic rod, a ball screw nut mechanism, etc. to achieve sliding drive of the support 3, and can be directly installed on the tooling base 1.

[0024] As attached Figure 3 As shown, in another specific embodiment, the rotating mechanism includes a rotating motor 21, a driving gear 24, a rotating seat 25 and a turntable 26. The rotating seat 25 is disc-shaped and is installed at the upper end of one side of the tooling base 1. A semicircular rotating groove is provided on the lower end surface of the turntable 26. The turntable 26 is fitted and clamped on the upper end of the rotating seat 25 through the rotating groove, and the turntable 26 can rotate around the center of the disc-shaped turntable 25 through the rotating groove. The upper end of the turntable 26 is used to be hinged with the end of the rotating support plate 2. A protruding fan-shaped gear 23 is provided on one side of the turntable 26. The rotating motor 21 is installed on the tooling base 1. The rotating motor 21 is used to drive the driving gear 24 to rotate, and the driving gear 24 is meshed with the fan-shaped gear 23.

[0025] Thus, when in use, the driving gear 24 can be driven to rotate by rotating the motor 21, and the sector gear 23 can be driven to rotate, thereby driving the turntable 26 and the rotating support plate 2 thereon to rotate.

[0026] In a further embodiment based on the above, the rotating mechanism further includes a reducer 22, the output end of the rotating motor 21 is connected to the reducer 22, and the driving gear 24 is connected and driven to rotate through the reducer 22. In this way, the accuracy of the steering adjustment can be increased by setting the reducer 22.

[0027] Among them, in a further embodiment based on the above, the rotating mechanism further includes a sensor fixing plate 28, a sensor transmission shaft 27 and an angle sensor B20. The sensor transmission shaft 27 is installed at the center of the rotating seat 25 on the rotating disk 26. The angle sensor B20 is installed on the rotating seat 25 through the sensor fixing plate 28 and connected to the sensor transmission shaft 27 to detect the rotation angle of the sensor transmission shaft 27. In this way, when the rotating disk 26 rotates, the sensor transmission shaft 27 installed at the center of the rotating seat 25 on the rotating disk 26 is used to transmit active information to the angle sensor B20, and the angle sensor B20 collects relevant information for reference and adjustment by construction personnel.

[0028] In another specific embodiment, the rotating mechanism is hinged to the end of the rotating support plate 2 through a hinge structure 14. In this embodiment, the hinge structure 14 can also be limited by a cotter pin or other structure, and connected by a bolt or other structure for easy assembly and disassembly. In this embodiment, an angle sensor A18 can also be provided at the hinge structure 14 as required, so that the angle sensor A18 collects relevant information for reference and adjustment by construction personnel.

[0029] In another specific embodiment, the upper end of the support 3 is rotatably provided with several rollers for contacting the lower end surface line of the rotating support plate 2. In this embodiment, several rollers can be arranged in a row, or only one longer roller can be arranged. In this way, the rotating support plate 2 can be effectively supported by the rollers, and the setting of the rollers can prevent the rotating support plate 2 from interfering with the rotating support plate 2 when adjusting the angle or direction, thereby affecting the adjustment accuracy.

[0030] In another specific embodiment, the upper end of the support 3 is provided with a plurality of balls for point contact with the lower end surface of the rotating support plate 2. In this embodiment, the plurality of balls can be arranged in a row. In this way, the rotating support plate 2 can be effectively supported by the plurality of balls, and the arrangement of the balls can prevent the rotating support plate 2 from interfering with the rotating support plate 2 when adjusting the angle or direction, thereby affecting the adjustment accuracy.

[0031] As attached Figure 4 As shown, in another specific embodiment, it also includes a universal wheel telescopic rod 6 and a universal wheel 7. Several universal wheels 7 are arranged in a rectangular array at the lower end of the tooling base 1, and are respectively connected to the lower end of the tooling base 1 through the universal wheel telescopic rod 6. In this embodiment, four universal wheels 7 can be set, and are respectively set at the four corners of the lower end of the tooling base 1. The universal wheels 7 and the universal wheel telescopic rod 6 are detachably connected through hexagonal bolts A8, wherein the hexagonal bolts A8 can be M18x40x1.5 hexagonal bolts. In this embodiment, the universal wheels 7 can all be self-locking, so that the device can be provided with a convenient mobile function through the arrangement of several universal wheels 7, and the use height of the entire device can be adjusted as needed in conjunction with the universal wheel telescopic rod 6.

[0032] As attached Figure 7 As shown, in a further embodiment based on the above, a controller 16, a level sensor 17 and a battery 19 may also be provided, wherein the level sensor 17 is provided at the bottom center of the tooling base 1, for sensing whether the tooling base 1 is in a horizontal state, and the controller 16 is electrically connected to the level sensor 17 and the universal wheel telescopic rod 6, respectively, so that the controller 16 controls the universal wheel telescopic rod 6 to adjust the level accordingly according to the data collected by the level sensor 17, that is, the corresponding control is achieved by connecting the controller 16 to the servo motor of the universal wheel telescopic rod 6, and the relevant electrical equipment is normally connected to the battery 19.

[0033] During use, due to the assembly and team welding of large structural parts, for structures with high assembly or welding precision requirements, in order to efficiently and accurately meet the installation requirements, it may be necessary to level the structure in advance. The tooling trolley can provide a one-key leveling function through the controller 16, the horizontal sensor 17, the universal wheel telescopic rod 6 and the universal wheel 7, and automatically adjust the precision to facilitate subsequent operations; considering the safety during use, to prevent the parts from tilting during the process of aligning and positioning the universal wheel telescopic rod 6, the controller 16 will lock in time according to the real-time signal sent back by the horizontal sensor 17 to prevent the parts from tilting.

[0034] At the same time, in this embodiment, the controller 16 can also be connected to the above-mentioned rotating motor 21, telescopic mechanism, angle sensor B20 and angle sensor A18, so as to realize corresponding automatic adjustment control.

[0035] Specifically, the controller 16, the horizontal sensor 17, etc. are installed on the tooling base 1. The controller 16 can be set in the middle and rear position of the tooling base 1 to facilitate wiring and maintenance. A waterproof and flame-retardant shell is set outside the controller 16 to improve the safety level. After the control program is written into the controller 16, the functions of signal collection, signal processing and signal output can be realized; the horizontal sensor 17 is installed in the middle and lower part of the tooling base 1, and a horizontal sensor mounting plate is set in the middle and lower part of the tooling base 1. The advantage of setting a separate plate in the middle and lower part of the tooling base 1 is that the deformation of the tooling base 1 can be avoided to the greatest extent, so that the measurement data is more accurate. After the controller 16 processes the signal sent back by the horizontal sensor 17, an accurate angle value with the ground is obtained; the angle sensor A18 measures the angle by measuring the rotation angle of the rotating shaft in the hinge structure 14 at the rotating connection position. Two angle sensors A18 can be set at both ends of the rotating shaft at the rotating connection position. The measured data can be complementary during use. After the controller 16 processes the signal sent back by the angle sensor A18, an accurate angle value is obtained, so that the measurement data is more accurate. The battery 19 is installed in the middle and front position of the tooling base 1, which can make the center of gravity of the tooling trolley in the middle and balance the center of gravity when loading parts. A reinforced structure design is made at the position of the battery 19, which is more stable and reliable and not easy to tilt during use. In order to facilitate the protection, maintenance and repair of the battery 19, a detachable protective cover is designed.

[0036] As attached Fig. 9 As shown, in another specific embodiment, it also includes a fixing frame and several connecting plates, and the several connecting plates are installed at intervals on the upper end surface of the rotating support plate 2, and several limit blocks are installed vertically upward on the connecting plates. A connecting frame for connecting the product to be assembled is installed on the fixing frame, and an opening for the limit blocks to be inserted and mutually engaged is opened on the fixing frame. The product to be assembled can be detachably installed on the fixing frame through the upper connecting frame. In this way, the product to be assembled can be installed through the fixing frame, which is convenient for the disassembly and assembly of the product to be assembled. At the same time, by installing the product to be assembled through the fixing frame, it is convenient to adjust the structure or size of the fixing frame according to the size of different products to be assembled, without affecting the design and use of the rotating support plate 2 and other structures, so as to reduce the construction cost and increase the construction efficiency.

[0037] In this embodiment, the left and right sides of the rotating support plate 2 can be correspondingly provided with side limit structures 15 for limiting the deviation of the fixing frame, so as to prevent the left and right swing caused by external factors during the movement of the tooling and during use, and to prevent the left and right swing caused by the movement of the tooling, so as to ensure the stability of the fixing frame during use. This design structure is simple and convenient to install and adjust, and can be safe and reliable in the production process, thereby promoting the improvement of production efficiency. When in use, after the fixing frame and other structures are hung according to the corresponding positions, the bolts and nuts of the side limit structures 15 are used to fix it and the rotating support plate 2.

[0038] In this embodiment, a hexagonal bolt C11 for contacting the lower end of the fixing frame can be installed on the hinge structure 14. Thus, the end of the fixing frame can be lifted or lowered by the hexagonal bolt C11, thereby adding a certain fine-tuning means. The hexagonal bolt C11 can be an M16x30x1.5 hexagonal bolt.

[0039] As attached Figure 5 , Attachment Figure 6 and attached Fig.10 As shown, in a further embodiment based on the above, a through hollow structure is respectively provided on both sides of the rotating support plate 2 close to and away from the rotating mechanism, a contact plate for contacting the support 3 is provided on the lower end surface of the rotating support plate 2, and adjusting bolts are respectively threadedly connected on the connecting plates on both sides of the rotating support plate 2, and a through hole is correspondingly provided on the contact plate below the adjusting bolt, and the adjusting bolt can pass through the hollow structure of the rotating support plate 2 and the through hole of the contact plate in turn, and the adjusting bolt is used to abut against the lower end of the fixing frame, and correspondingly abut to raise or lower the distance between the fixing frame and the connecting plate, and at the same time, it will not contact the parts during use, that is, it will not cause damage to the paint of the parts. In this way, the distance between the fixing frame and the connecting plate can be further fine-tuned by driving the adjusting bolts at different positions as needed, thereby achieving further fine-tuning of the installation angle of the product to be assembled. In this embodiment, the adjusting bolts can be set at the four corners below the fixing frame.

[0040] As attached Figure 1 and attached Figure 2As shown, specifically, if the style of the fixing frame A4 is required, the specific position of the connecting frame A10 thereon can be designed according to the product to be installed, wherein the position of the hexagonal bolt B9 as the adjusting bolt can be changed according to the style of the fixing frame A4, wherein the hexagonal bolt B9 can be an M20x70x1.5 hexagonal bolt; if the style of the fixing frame B5 is required, the specific position of the connecting frame B13 thereon can be designed according to the product to be installed, wherein the position of the hexagonal bolt D12 as the adjusting bolt can be changed according to the style of the fixing frame B5, wherein the hexagonal bolt D12 can be an M16x60x1.5 hexagonal bolt. This solution only requires designing different fixing frames for different parts, reducing production costs and promoting the improvement of production efficiency.

[0041] The support 3 is connected with the rotatable plate 2 and the rotatable plate 2 by a screw, a guide rail and a high-torque servo motor, and the support 3 is driven by the rotatable plate 2 to move along the guide rail, so as to realize the adjustment of the assembly angle of the rotatable plate 2 and the parts thereon. The support 3 and the rotatable plate 2 are connected by a screw, a guide rail and a high-torque servo motor, and the rotatable plate 2 and the rotatable plate 2 are adjusted by the screw. The design is suitable for disassembly and replacement, and this design structure is simple, convenient to adjust, stable to use, and promotes the improvement of production efficiency; the fixed frame is connected to the rotating support plate 2 by a wall-mounted design, and the fixed frame can be designed according to the parts to be assembled or welded as needed. Before installing it on the rotating support plate 2, the parts to be assembled must be installed in advance, and then it is hoisted onto the rotating support plate 2 as a whole. This design is convenient for its hoisting and is conducive to the subsequent micro-adjustment of various angles of the adjusting bolts; the universal wheel telescopic rod 6 and the universal wheel 7 are arranged in a coordinated manner and installed on the four corners of the tooling base 1 for leveling and height adjustment of the tooling. The universal wheel 7 is installed at the lower end of the universal wheel telescopic rod 6, and is fixed to the plate body below the universal wheel telescopic rod 6 by bolts and other structures and fixed, so as to facilitate the subsequent movement and position adjustment of the tooling. The universal wheel 7 adopts a brake design to facilitate its fixation; the adjusting bolt can make micro-adjustments to the position of the fixed frame and the parts to be assembled thereon, assisting workers to complete the final assembly or welding effect.

[0042] Among them, considering that the rotating pallet 2 and the tooling base 1 adopt a hinge-type rotating design, after the assembly parts are installed on the rotating pallet 2, the support 3 is prevented from moving. Therefore, after the angle is adjusted to the appropriate position, the high-torque servo motor connected to the support 3 through the screw is locked to prevent safety problems after the parts are installed.

[0043] Among them, the tooling base 1 can be designed with a lightweight chemical Chinese-shaped structure using square steel, which is light while ensuring strength. The battery installation area and the controller installation area can be set on the tooling base 1 as needed, and both are provided with protective shells and have waterproof grade requirements. The tooling base 1 is also provided with a horizontal sensor mounting seat and an angle sensor mounting seat as needed. The above mounting seats can all adopt an adjustable design to facilitate the later debugging of the sensors.

[0044] The patented structure of the present invention is simple, with low manufacturing cost, multi-degree-of-freedom adjustment, simple and convenient use, and can significantly improve production efficiency. It has high versatility, high adaptability, strong interchangeability, and can be used in coordination with multiple devices. It plays an important and positive role in the installation and welding of parts of most heavy equipment. It is stable to use during the production process, and is beneficial to reducing processing costs and improving processing efficiency for single-piece small-batch production.

[0045] A specific implementation of this scheme is as follows: First, install the parts on the fixed frame, and the connection method adopts limit and bolt compression. The matching position of the fixed frame and the parts is installed according to the matching position size designed in advance; according to the angle of the corresponding assembly parts, adjust the rotating support plate 2 to a suitable angle. After the angle is adjusted to a suitable position, lock the high-torque servo motor connected to the support 3 through the lead screw to prevent safety problems after the parts are installed; before hoisting the parts, first level the tooling trolley to ensure safety and accuracy of position during installation. At this time, a leveling signal can be input to the controller 16. The controller 16 controls the servo motors of the four universal wheel telescopic rods 6 respectively through the signal transmitted by the horizontal sensor 17 to achieve one-button leveling. The universal wheel telescopic rod 6 and the tooling base 1 are connected with a standard thread, which is convenient for adjustment during use; hoist the installed fixed frame and parts as a whole, and adjust them according to the positions of multiple hanging points on the rotating support plate 2 through the matching position size designed in advance. After adjustment, hang it on the rotating support plate 2.

[0046] The fixed parts are moved to the appropriate position of the assembled or welded products by the tooling trolley. According to the height and level of the adjusted parts, the universal wheel telescopic rod 6 is controlled by the controller 16 to realize the precise height adjustment of the parts. When adjusting the accurate vertical position of the parts, the verticality of the parts can be detected with the help of external auxiliary equipment such as a plumb bob total station, and the lateral verticality and welding gap between the parts on the tooling trolley and the assembled or welded products can be adjusted by measuring the external auxiliary measuring equipment total station. After determining the position, the brakes of the universal wheel 7 need to be locked to prevent the position from moving during the fine-tuning process; the accurate welding position is found by measuring the external auxiliary measuring equipment total station, and the parts are further fine-tuned as needed by using the adjusting bolts on the rotating support plate 2 to ensure the final position requirements and carry out subsequent assembly operations.
