[0041] like Figures 1 to 6 As shown, an adjustable material rack includes a base 1;

[0042] Pillars 2, the base 1 is detachably provided with a plurality of the pillars 2 distributed in an array;

[0043] A plurality of frames 3, each of the frames 3 having corners movably connected to different pillars 2;

[0044] Connecting rod 4, a plurality of connecting rods 4 are movably connected to the frame 3; a plurality of limiting rods 41 and a plurality of supporting components 42 are movably connected to the connecting rod 4,

[0045] The limiting rod 41 is used to limit the edge of the workpiece 5 , and the supporting assembly 42 is used to support the workpiece 5 on the frame 3 .

[0046] The adjustable material rack of the present invention is particularly suitable for placing and supporting aluminum alloy structural parts (workpieces 5 ), and of course, it can also be suitable for placing and supporting other types of workpieces 5 .

[0047] Specifically, the adjustable material rack of the present solution is mainly composed of a base 1, pillars 2 and a frame 3. A plurality of vertical pillars 2 are arranged on the base 1. The plurality of pillars 2 are grouped together to form an installation space. The frame 3 is located in the installation space and connected to the pillars 2. The outer contour of the frame 3 in the present embodiment can be a polygon, such as a triangle or a quadrilateral, preferably a rectangle. In this case, the four pillars 2 are together to form an installation space. The four corners of each frame 3 are movably connected to the pillars 2 (such as bolted or sliding connections), and a plurality of frames 3 distributed at intervals can be installed on every four pillars 2 in the height direction. Since the frame 3 is movably connected to the pillars 2, that is, the spacing between two adjacent frames 3 can be freely adjusted, and workpieces 5 of different models can be placed on the frame 3 after adjusting the spacing according to needs.

[0048] In addition to the adjustable vertical spacing between two adjacent frames 3, the frame 3 of this solution is also provided with a plurality of movably connected connecting rods 4, that is, the horizontal spacing between two adjacent connecting rods 4 can also be adjusted to adjust the placement density between the workpieces 5 and improve the quality of the workpieces 5. In addition, the limit rod 41 and the support assembly 42 are also movably installed on the connecting rod 4, that is, the setting position of the limit rod 41 and the support assembly 42 on the connecting rod 4 can also be freely adjusted. Therefore, the limit rod 41 can limit the edges of workpieces 5 of various shapes / sizes, specifically, the limit rod 41 presses against the outer edge of the workpiece 5 to prevent the workpiece 5 from falling off the frame 3; multiple support rods can be installed at different positions on the connecting rod 4 according to needs to support the key parts of workpieces 5 of different shapes / sizes, and the adaptability range is wider.

[0049] Furthermore, the support column 2 is provided with a plurality of first connection holes 21 spaced apart along the height direction thereof, and each corner of the frame 3 is provided with a detachable frame connection member 31, and each frame connection member 31 is connected to any of the first connection holes 21 by a first bolt;

[0050] Any of the frame connectors 31 of each of the frames 3 are installed in the first connecting holes 21 at the same height.

[0051] In this embodiment, bolt connection is preferably used to complete the movement of the frame 3 on the pillar 2. The frame 3 can be fixed in any first connection hole 21 on the pillar 2 through the frame connector 31 and the first bolt. When the vertical spacing between two adjacent frames 3 needs to be adjusted, the first bolt is unscrewed from the previous first connection hole 21, and the frame 3 and the frame connector 31 are moved to the required height, and then the first bolt is tightened in another first connection hole 21. The overall structure is simple, and the assembly and adjustment methods are more diverse.

[0052] Further, the frame 3 includes a first connecting arm 32, a second connecting arm 33, a third connecting arm 34 and a fourth connecting arm 35 connected end to end, and the first connecting arm 32, the second connecting arm 33, the third connecting arm 34 and the fourth connecting arm 35 form the frame 3 with a rectangular cross section;

[0053] At least one fifth connecting arm 36 is further provided in the frame 3, and two ends of the fifth connecting arm 36 are detachably provided on the second connecting arm 33 and the fourth connecting arm 35 respectively;

[0054] A plurality of second connecting holes 321 are arranged at intervals on the first connecting arm 32, a plurality of third connecting holes 341 are arranged at intervals on the third connecting arm 34, a plurality of fourth connecting holes 361 are arranged at intervals on the fifth connecting arm 36, a plurality of connecting rods 4 are arranged between the first connecting arm 32 and the fifth connecting arm 36, and both ends of the connecting rods 4 are respectively connected to any of the second connecting holes 321 and any of the fourth connecting holes 361 through second bolts 43, a plurality of connecting rods 4 are also arranged between the third connecting arm 34 and the fifth connecting arm 36, and both ends of the connecting rods 4 are respectively connected to any of the third connecting holes 341 and any of the fourth connecting holes 361 through third bolts 44.

[0055] In this embodiment, the frame 3 is preferably rectangular, and is respectively composed of a first connecting arm 32, a second connecting arm 33, a third connecting arm 34 and a fourth connecting arm 35 connected end to end, wherein the long sides are the first connecting arm 32 and the third connecting arm 34. A fifth connecting arm 36 is also provided in the middle of the rectangular frame 3, and the fifth connecting arm 36 may be one or two, and the two ends of the fifth connecting arm 36 are connected to the second connecting arm 33 and the fourth connecting arm 35 by bolts. The fifth connecting arm 36 is usually arranged in parallel with the first connecting arm 32 or the third connecting arm 34, and preferably two fifth connecting arms 36 are arranged, so that the mounting holes 4211 of the two groups of connecting rods 4 connected to the first connecting arm 32 or the third connecting arm 34 do not interfere with each other.

[0056] Since the first connecting arm 32 is provided with a plurality of second connecting holes 321, and one group of the fifth connecting arms 36 is provided with a plurality of fourth connecting holes 361, the connecting rod 4 can be set at any position on the above two connecting arms, and the number of the connecting rods 4 set on the above two connecting arms can also be freely adjusted. Similarly, since the third connecting arm 34 is provided with a plurality of third connecting holes 341, and the other group of the fifth connecting arms 36 is also provided with a plurality of fourth connecting holes 361, the connecting rod 4 can also be set at any position on the above two connecting arms, and the number of the connecting rods 4 set on the third connecting arm 34 and the second group of the fifth connecting arms 36 can also be freely adjusted according to demand, and the adaptability range is wider.

[0057] Furthermore, the support assembly 42 includes a support seat 421 , and each of the connecting rods 4 is provided with a plurality of support seats 421 of different heights.

[0058] In the present embodiment, bolt connection is adopted to replace the welding fixing method. Through the standardized spacing design between the first connecting hole 21 (screw hole), the second connecting hole 321, the third connecting hole 341, and the fourth connecting hole 361, and equipped with a plurality of support seats 421 of different heights (such as 3, 4 or more kinds), professional material racks of various specifications can be flexibly combined to meet diverse needs, ensuring that the adjustable material rack of the present solution is compatible with various types of workpieces 5, and can be easily and flexibly adjusted according to the actual degree of deformation of the workpiece 5 during the heat treatment process, so as to achieve the best use effect.

[0059] Furthermore, the support assembly 42 further includes an adjustment rod 422, and a mounting hole 4211 is formed at one end of the support seat 421, and the bottom end of the adjustment rod 422 is inserted into the mounting hole 4211;

[0060] The other end of the support seat 421 is provided with a plug-in column 4212, and a plurality of fifth connection holes 45 are arranged at intervals on the connection rod 4, and the plug-in column 4212 is inserted into any of the fifth connection holes 45;

[0061] Another support seat 421 is stacked on the support seat 421 , and the plug-in column 4212 located at the bottom is inserted into the mounting hole 4211 of the support seat 421 located at the top.

[0062] The connecting rod 4 is provided with a plurality of support seats 421 of different heights. When the fixed support seat 421 still fails to contact and press against the inner wall of the workpiece 5, an adjustment rod 422 of different heights can be provided above it (usually the adjustment rod 422 is locked on the support seat 421 by bolts) to increase the height of the support seat 421, so as to better support various types of workpieces 5. The bottom end of the adjustment rod 422 is inserted and clamped in the mounting hole 4211 of the support seat 421. The two can be separated only by manual pulling. Generally, the two are tightly combined.

[0063] In addition to the adjustment rod 422 being inserted tightly into the mounting seat, the two mounting seats can also overlap each other, that is, the plug-in column 4212 of the upper mounting seat is inserted tightly into the mounting hole 4211 of the next mounting seat to adjust the overall height of the mounting seat to better adapt to the support and fixation of the workpiece 5.

[0064] Furthermore, the support assembly 42 also includes a first adjustment plate 423, a first end 4231 of the first adjustment plate 423 is provided with a first adjustment groove 4232, one end of the fourth bolt 424 is movably arranged in the first adjustment groove 4232, the other end of the fourth bolt 424 passes through the first adjustment groove 4232 and is detachably connected to the mounting hole 4211, and the adjustment rod 422 is detachably arranged at the second end 4233 of the first adjustment plate 423.

[0065] In order to further adjust the supporting position of the adjusting rod 422, the present scheme is also provided with a first adjusting plate 423, and the first adjusting plate 423 is usually set on the mounting seat through the fourth bolt 424. Since the first adjusting plate 423 is provided with a first adjusting groove 4232, when the fourth bolt 424 is not tightened, the fourth bolt 424 can move in the waist-shaped first adjusting groove 4232. Since the adjusting rod 422 is fixed at the second end 4233 of the first adjusting plate 423, when the first adjusting plate 423 is translated a certain distance, the horizontal position of the adjusting rod 422 fixed thereto can also be fine-tuned to better support the key parts of the workpiece 5.

[0066] Furthermore, if Figures 2 to 4 As shown, the second end 4233 extends horizontally, and the adjusting rod 422 is vertically arranged on the second end 4233; or, the second end 4233 is bent toward or away from the connecting rod 4, and the adjusting rod 422 is transversely arranged on the second end 4233.

[0067] Since the workpiece 5 to be supported and fixed is irregular in shape and rather special overall, in addition to supporting the bottom surface of the workpiece 5, part of the side wall surface of the workpiece 5 also needs to be pressed tightly to prevent it from deforming. Therefore, the first adjustment plate 423 of this solution has three shapes, the first is a horizontally extending plate, the second is a second end 4233 of the first adjustment plate 423 is bent vertically downward, and the third is a second end 4233 of the first adjustment plate 423 is bent vertically upward. Users can set the corresponding first adjustment plate 423 at different positions according to their needs, so as to better press and support the workpiece 5.

[0068] Furthermore, the support assembly 42 further includes a positioning block 425, and the positioning block 425 is detachably disposed on the top of the support seat 421;

[0069] The positioning block 425 is provided with a limiting protrusion 4251 , and the limiting protrusion 4251 is used to be clamped in the positioning groove 51 of the workpiece 5 ; the positioning block 425 is also provided with a plurality of through holes 4252 , and the through holes 4252 are located at the periphery of the limiting protrusion 4251 .

[0070] The positioning block 425 is usually larger in size than the support seat 421 and is in the shape of a large disc, which can better support the relative center position of the bottom surface of the workpiece 5. The limiting protrusion 4251 on the positioning block 425 is inserted into the positioning groove 51 of the workpiece 5, which has a good positioning effect. The positioning block 425 is also provided with a plurality of through holes 4252, which can reduce the weight and manufacturing materials of the positioning block 425.

[0071] Furthermore, the frame connector 31 includes a first side wall 311 and a second side wall 312 connected end to end, the first side wall 311 and the second side wall 312 form the frame connector 31 with an L-shaped vertical section, the frame 3 is arranged above the first side wall 311, and the second side wall 312 is connected to the first connection hole 21 of the pillar 2 through at least one first bolt;

[0072] A stopper 313 for limiting the frame 3 is further provided above the first side wall 311 ; a reinforcing portion 314 is further provided between the bottom end of the first side wall 311 and the second side wall 312 .

[0073] The frame connector 31 is usually L-shaped, and the second side wall 312 of the frame connector 31 is set close to the pillar 2. The second side wall 312 is connected and fixed to the pillar 2 by a first bolt. The frame can also be installed on the first side wall 311 by bolts. Frame connectors 31 are provided at the four corners of the frame to prevent it from moving horizontally on the pillar 2.

[0074] Of course, in this embodiment, in addition to using bolts to fix the first side wall 311 and the corners of the frame, a stopper 313 can also be used to limit the frame. A stopper 313 is also provided on the first side wall 311. The horizontal cross section of the stopper 313 is also L-shaped, which can limit the four corners of the frame to prevent the frame from moving. It is also possible to use bolts to fix the first side wall 311 and the frame, and to set the stopper 313 to limit the frame.

[0075] Furthermore, a second adjustment plate 46 is provided on the connecting rod 4, and a second adjustment groove 461 is opened at one end of the second adjustment plate 46. One end of the fifth bolt 462 is movably set in the second adjustment groove 461, and the other end thereof passes through the second adjustment groove 461 and is detachably connected to the fifth connecting hole 45.

[0076] Similarly, in this embodiment, in order to fine-tune the horizontal position of the limit rod 41, a second adjustment plate 46 is set on the connecting rod 4, and the limit rod 41 is set on the second adjustment plate 46. Since the second adjustment plate 46 is provided with a second adjustment groove 461, when the fifth bolt 462 is not tightened, the fifth bolt 462 can move in the waist-shaped second adjustment groove 461. Since the limit rod 41 is fixed on the second adjustment plate 46, when the second adjustment plate 46 is translated a certain distance, the horizontal position of the limit rod 41 fixed thereto can also be fine-tuned, so as to better limit the edge of the workpiece 5.

[0077] In this solution, the sizes of all the first connection holes 21, the second connection holes 321, the third connection holes 341, the fourth connection holes 361 and the fifth connection holes 45 can be M10 thread holes, and the mounting hole 4211 of the support seat 421 can also be M10 thread holes.

[0078] Further, the top of the adjusting rod 422 is arc-shaped or flat-shaped. In this solution, the top of the adjusting rod 422 can be adjusted to an arc-shaped or flat-shaped shape according to different supporting parts of the workpiece 5, that is, a flat-headed adjusting rod 422 or a round-headed adjusting rod 422 can be used.

[0079] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
