[0002] When horizontal printing is used to process workpieces, if the axial size of the workpiece is too large relative to the radial size, such workpieces are likely to cause a load on the rotating shaft mechanism of the clamp; for arc additive technology, during the processing, the workpiece will generate a high temperature due to processing, and may be deformed by heat or its own weight; therefore, when using a horizontal bed to produce long-axis workpieces, a support device must be added; the surface of the workpiece produced by arc additive manufacturing technology has interlayer fusion marks. If a traditional rigid support mechanism is used, the rigid uneven contact of the surface will generate huge alternating stress, which will greatly reduce the life of the parts of the rotating shaft mechanism and affect the forming of the workpiece; at the same time, most of the existing support mechanisms cannot move in multiple directions, and cannot reasonably match the support requirements of the processed workpiece during use.

[0023] Example 1

[0024] like Figures 1 to 3 As shown, a support mechanism of a horizontal additive device includes a horizontal transverse mechanism 1, a vertical mechanism 2 and a horizontal longitudinal mechanism 3;

[0025] The horizontal transverse mechanism 1 includes a horizontal guide rail 11 and a first slider 12 that slides along the horizontal guide rail 11;

[0026] The vertical mechanism 2 includes a cylinder 23 and a sliding mechanism; the sliding mechanism includes a vertical guide rail 24 and a second slider 25 that slides along the vertical guide rail 24; the cylinder 23 is fixedly connected to the sliding mechanism through a shell for driving the sliding mechanism, and the shell is used to support the slider mechanism and is fixed on the first slider; specifically, the shell includes an outer shell 21 and an inner shell 22; the outer shell 21 includes an outer bottom plate 211 fixed to the first slider 12 and an outer side plate 212 fixedly connected to the outer bottom plate 211 as an integral structure; the inner shell 22 includes an inner top plate 223 fixedly connected to the outer side plate 212, an inner side plate 222 fixedly connected to the vertical guide rail 24 through the second slider 25, and an inner bottom plate 221 fixedly connected to the cylinder 23 as an integral structure; wherein, a through hole is provided on the inner bottom plate 221, and the cylinder 23 includes a cylinder body 231 and a piston rod 232, the cylinder body 231 is placed on the inner bottom plate 221, and the piston rod 232 is placed under the inner bottom plate 221 through the through hole. Because the inner shell 22 is an integrated structure, when the inner bottom plate 221 moves, it can drive the inner side plate 222 and the inner top plate 223 to move together. At the same time, the inner side plate 222 can be provided with one side or multiple sides, as long as the second slider 25 fixed to the inner side plate 222 can follow the inner bottom plate 221 to move up and down along the vertical guide rail 24.

[0027] The horizontal longitudinal mechanism 3 includes a longitudinal guide rail 31, a third slider 32, and a support assembly 33. The longitudinal guide rail 31 is fixedly connected to the housing, and the support assembly 33 moves translationally on the longitudinal guide rail 31 via the third slider 32. Specifically, the longitudinal guide rail 31 is fixedly connected to the inner top plate 223, the vertical mechanism 2 is fixed to the first slider 12 of the horizontal transverse mechanism 1, and the horizontal longitudinal mechanism 3 is fixed to the inner top plate 223 of the inner housing 22 of the vertical mechanism 2.

[0028] Specifically, the support assembly 33 includes support wheels 331, a support base plate 332, and support side plates 333. The support side plates 333 are provided with through-holes for mating with the support wheels 331 and grooves 3331 for supporting the workpiece to be processed. The support wheels 331 are fixedly assembled to the support base plate 332 through the through-holes. There are two support wheels 331, which are used to secure the workpiece to be processed by being arranged on the left and right sides.

[0029] Specifically, the groove 3331 is triangular in shape. The groove 3331 of the support side plate 333 is designed to allow the alternating stress to which the workpiece is subjected during machining to be transferred to the third slider 32 via the groove 3331. When the third slider 32 is subjected to the force of the workpiece, it slides via the longitudinal guide rail 31, thereby alleviating the eccentric effect caused by the alternating stress. At this time, the support assembly 33 will passively move laterally a certain distance to ensure a balance between the upward support force and the alternating stress.

[0030] The working process of this embodiment is as follows: first, the workpiece to be processed is installed on the rotating shaft mechanism, and the position of the first slider 12 on the horizontal guide rail 11 is manually adjusted according to the axial length of the workpiece to be processed. After adjustment, the pressure regulating system is turned on, and the cylinder 23 is inflated. The piston rod 232 is squeezed by the gas and tends to move inside the cylinder body 231. When the gas is further increased, since the piston rod 232 is fixed on the inner bottom plate 221 and the inner shell 22 is an integrated structure, the inner bottom plate 221 moves up and down, driving the inner side plate 222 to move up and down, and the second slider 25 on the inner side plate 222 moves up and down along the guide rail, and the cylinder 23 and the inner shell 22 are linked. Since the longitudinal guide rail 31 is fixed on the inner top plate 223, the movement of the cylinder 23 simultaneously drives the horizontal longitudinal mechanism 3 to move, so that the two support wheels 331 are placed under the workpiece. When the workpiece is being processed, alternating stress will be generated due to the processing. At this time, the workpiece will transmit the alternating stress to the horizontal longitudinal mechanism 3 in contact with it. Specifically, the support wheel 331 of the support assembly 33 and the groove 3331 of the support side plate 333 receive the force of the workpiece. This force causes the support assembly 33 to slide on the longitudinal guide rail 31 through the third slider 32, thereby changing the eccentricity of the workpiece, thereby balancing the alternating stress on the workpiece.

[0031] Example 2

[0032] like Figures 1 to 3 As shown, based on the first embodiment, the horizontal transverse mechanism 1 further includes evenly distributed fixing holes 13 and a dustproof housing 21; the outer plate 212 of the vertical mechanism 2 is provided with a lifting slot 2121 and two latching slots 2122, with the latching slots 2122 positioned to one side of and communicating with the lifting slot 2121. Because the outer plate 212 of the vertical mechanism 2 is used to prevent dust, the outer plate with the lifting slots 2121 and the latching slots 2122 can be located on any side, as long as it does not affect the proper movement of other components and matches the position of the fixing holes of the horizontal transverse mechanism 1.

[0033] Specifically, the first limiting assembly includes a first limiting rod and a second limiting rod, the second limiting rod being vertically fixed to the first limiting rod; the first limiting rod is placed in the fixing hole 13, and the second limiting rod extends from the slot 2122. The first limiting assembly is used to fix the support mechanism after the position is adjusted to prevent the support mechanism from moving due to excessive force.

[0034] Specifically, the second limiting assembly includes a third limiting rod 2123, a limiting block 2125, and a fourth limiting rod 2124. The limiting block 2125 has a through hole for the third limiting rod 2123 to pass through. The limiting block 2125 is fixed to the outer plate 212. The fourth limiting block 2125 is vertically fixed to the third limiting rod 2123. The third limiting rod 2123 is placed in the fixing hole 13, and the third limiting rod 2123 extends from the slot 2122. The second limiting assembly is used to fix the support mechanism after its position is adjusted to prevent the support mechanism from moving due to excessive force.

[0035] The working process of this embodiment includes a support adjustment process and a fixing process. Specifically, the support adjustment process is as follows: first, the workpiece to be processed is installed on the rotating shaft mechanism. According to the axial length of the workpiece to be processed, the position of the first slider 12 on the horizontal transverse mechanism 1 on the horizontal guide rail 11 is manually adjusted. After adjustment, the pressure regulating system is turned on and the cylinder 23 is inflated. The piston rod 232 is squeezed by the gas and has a tendency to move inside the cylinder body 231. When the gas is further increased, since the piston rod 232 is fixed to the inner bottom plate 221 and the inner shell 22 is an integrated structure, the inner bottom plate 221 moves up and down, driving the inner side plate 222 to move up and down. The second slider 25 on the inner side plate 222 moves up and down along the guide rail, and the cylinder 23 and the inner shell 22 are linked. Since the longitudinal guide rail 31 is fixed to the inner top plate 223, the movement of the cylinder 23 simultaneously drives the horizontal longitudinal mechanism 3 to move, and the two support wheels 331 are placed below the workpiece to be processed. Specifically, since there are interlayer weld marks on the surface of the additively manufactured workpiece, when the support wheel contacts the weld mark, a longitudinal unbalanced force will be generated, and alternating stress will be generated during the rotation of the workpiece; therefore, the present application designs a horizontal longitudinal mechanism 3 to solve the generated alternating stress. Among them, the support wheel 331 of the support assembly 33 in the horizontal longitudinal mechanism 3 and the groove 3331 of the support side plate 333 are subjected to a force, which causes the support assembly 33 to slide on the longitudinal guide rail 31 through the third slider 32, thereby changing the eccentricity of the processed workpiece, thereby balancing the alternating stress. The fixing process is: when the first limit assembly is used, after the position is adjusted, the second limit rod is adjusted to a suitable position through the lifting groove 2121 on the outer plate 212, and then slides to the slot 2122 on the outer plate 212 to extend and then fix the first limit rod with force in the fixing hole 13 of the horizontal transverse mechanism 1. When the second limiting assembly is used, after the position is adjusted, the third limiting rod 2123 is inserted into the limiting block 2125, and then the fourth limiting rod 2124 is fixed on the third limiting rod 2123, so that the fourth limiting rod 2124 is adjusted to a suitable position through the lifting slot 2121 on the outer plate 212, and then slides to the slot 2122 on the outer plate 212 to extend out and then fix the third limiting rod 2123 with force in the fixing hole 13 of the horizontal transverse mechanism 1.

[0036] In summary, the present invention satisfies the use in multiple directions by setting multiple guide rails and sliders in different directions, and at the same time designs a support component 33 on its horizontal longitudinal mechanism 3 to alleviate the alternating stress on the processed workpiece. Therefore, the support mechanism can adjust the support force within a large range, has strong versatility, and reduces the scrap rate of the processed workpiece.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
