detailed description

The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

As shown in Fig. 1, the ultra-wide embroidery machine steady-state frame provided by the present invention includes an embroidery machine girder 1, several backpacks 2 for reinforcing the girder, a base 3, a backpack reinforcing plate 4, a shock absorbing plate 5, and The main pillar between the machine frame and the base 6, the front auxiliary pillar 7 for strengthening the embroidery machine frame and the main pillar, the rear auxiliary pillar 8 for strengthening the main pillar, the suspension of the embroidery machine head 9, and the front auxiliary pillar 7 for reinforcement The front auxiliary sub-pillar 10 etc. of the front.

The crossbeam of the embroidery machine of the present invention adopts a double-beam structure placed horizontally side by side; the backpack is L-shaped, and one of the right-angled arms penetrates into the inside of the crossbeam and then is fixedly connected to the inner wall of the crossbeam (it can be seen in the figure: one of the backpack The right-angle arm horizontally passes through the reserved hole on the girder and then is affixed to the inner wall of the girder), while the other right-angle arm is vertically downward and affixed to the base of the embroidery machine. The fixed connection between the backpack and the base makes the stability of the whole structure better guaranteed. The premise of the large self-weight base of the base ensures the stability of the entire embroidery machine during the movement without jumping.

The embroidery machine beam includes two beams, each beam is a hollow cuboid structure, its length is controlled within the range of 16.8m, the size of the entire section is 500×300mm, and the wall thickness is 10mm. The two beams are placed side by side horizontally and Welded together to form a whole.

The embroidery machine base 3 is a steel frame structure, which is located in the priority installation position in the structure of the embroidery machine. First arrange two square tubes 18 of the same length in parallel, place the triangular iron frame 11 that needs to be fixed between the two square tubes, and then spot-weld first to determine the relative position between them, and wait for the relative position After being determined, weld their structures again. The whole process should pay attention to the structural deformation in the welding process. After the main steel frame is determined, weld the auxiliary steel frame 19 again. The auxiliary steel frame is the same height as the square pipe. The steel frame is also a structure similar to the square tube, so a pair of auxiliary steel frames weld the two ends of the two rectangular tubes together to form a zigzag shape.

The main pillar 6 of the embroidery machine is a square tube with a thickness of 20mm, which is vertically placed on the upper surfaces of the two auxiliary steel frames respectively, and their relative positions in the horizontal direction will completely coincide, so that the sides of a pair of main pillars form a One surface of the can pass parallel to the side of the lower base, and the entire installation process is also completed by welding.

The structure of the front auxiliary pillar 7, the rear auxiliary pillar 8, and the front auxiliary auxiliary pillar 10 of the embroidery machine is a steel pipe similar to the structure of the main pillar, but different in size range; the front auxiliary pillar 7 and the rear auxiliary pillar The pillar 8 is erected on the lower base, and the main pillar is clamped in the middle to play the role of reinforcement. The front auxiliary pillar 10 is used to strengthen the front auxiliary pillar 7 to further support the main pillar.

The knapsack reinforcement plate 4 of the embroidery machine is installed on the girder after the position of the knapsack hole on the girder is determined; specifically, the backboard reinforcement plate is installed on the outer side of the first beam directly in contact with the knapsack (See Figure 7: When installing, one right-angled arm of the backpack first passes through the opening of the backplane reinforcing plate horizontally, and then passes through the reserved holes on the two beams). During the process, it is necessary to ensure that the holes of the backpack reinforcement plate are exactly the same as the reserved holes on the girder, so that there will be no deviation during the installation of the backpack, and avoid the situation that it cannot be installed.

When the crossbeam of the embroidery machine is installed on the main pillar, the damping plate 5 needs to be welded to the bottom surface of the crossbeam, and then the whole crossbeam is placed on the main pillar for welding and fixing. As a preference, a damping plate for buffering the vibration of the beam is provided between the embroidery machine beam and the base; the damping plate is composed of three steel plates, and two smaller steel plates 5-1 are placed in parallel and connected to each other. Space apart a certain distance (usually distance is 3-5mm and get final product), and a larger steel plate 5-2 consistent with the cross-section of the main pillar of the embroidery machine is set as the base plate.

There is a reserved hole on the girder for placing the backpack. This hole needs to be cut before the girder is welded on the main pillar. Because the entire backpack needs to go through the entire girder, before the two separate beams are welded, it is necessary to process a reserved hole that runs horizontally through both sides on one beam, and a reserved hole that runs through one side on the other beam. hole (the corresponding position on the surface of the inner cavity on the other side is not opened); because the structural shapes of the two beams are completely consistent, the relative positions of the reserved holes determined on the two beams should be exactly the same , to ensure that there will be no deviation when the entire backpack is installed.

The knapsack 2 above the embroidery machine is in contact with the inner side of a crossbeam hanging the head suspension of the embroidery machine through the opening of the knapsack reinforcing plate and the reserved hole on the girder. When installing the knapsack, wait until the knapsack The end face of the horizontal right-angle arm touches the inner side of a single beam, and then welds with a welding process at the place where the backpack reinforcement plate contacts the backpack. Using the same method, install the six backpacks on the girder in turn, making sure that their heights in the horizontal position are exactly the same. Finally, the lower end of the backpack is connected to the base of the embroidery machine, which is also fixed by welding. During the whole welding process, it is necessary to consider whether there will be welding deformation, and the welding deformation must be eliminated during the installation process, so that the entire structure can complete the assembly task as required.

The working principle of the present invention is:

As shown in Figure 2, the working area of the entire embroidery machine is very wide, and deflection deformation will inevitably occur under the drive of the embroidery machine head. The ultra-wide stable frame is equipped with a backpack at the position of the maximum deflection deformation, and Let the upper end of the backpack run through the entire frame of the embroidery machine, which strengthens the stability of the entire embroidery machine. In the mechanical analysis of the simulation, the maximum deflection deformation is controlled within 1mm. The mutual extrusion of the front and rear auxiliary pillars improves the stability of the entire main pillar, thereby ensuring the dynamic stability of the girder and preventing the girder from shaking back and forth, thereby improving the working accuracy of the entire embroidery machine and improving the embroidery as much as possible. On the basis of efficiency, the quality of finished embroidery can be better completed.

Finally, it should be noted that what is listed above are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All deformations that can be directly derived or associated by those skilled in the art from the content disclosed in the present invention should be considered as the protection scope of the present invention.
