Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a supporting chassis with a height adjustment function. Background Art

[0002] The production process of a machine refers to the entire process of making products from raw materials (or semi-finished products). For machine production, it includes the transportation and storage of raw materials, preparation for production, manufacturing of blanks, processing and heat treatment of parts, assembly and debugging of products, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, and regard the production process as a production system with input and output. The support frame is a commonly used tooling for machining mechanical parts. The parts to be processed are placed on the support frame to facilitate the machine tool to perform the required processing until the finished product is completed, and then the parts can be easily removed.

[0003] At present, most of the existing support frames are of fixed height when in use. If the height of the processing machine needs to be constantly changed during use, the number of bottom support frames needs to be constantly replaced. The support frames are relatively cumbersome to install and disassemble, which makes the device inconvenient to use and easily reduces processing efficiency. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a support frame with a height adjustment function, including a support platform 1, connecting columns 11 are fixedly installed at the four corners of the lower end of the support platform 1, and a supporting leg 15 is installed at the lower end of each connecting column 11. A fixing plate 13 is fixedly installed inside the support platform 1, and a connecting plate 16 is installed at the lower end of the fixing plate 13. Two second support rods 19 are rotatably installed at the lower end of the connecting plate 16, and two first support rods 18 are rotatably installed at the lower end of the connecting plate 16. The lower ends of each second support rod 19 and the first support rod 18 are installed with the same auxiliary base 21.

[0020] In this embodiment, Figure 1 and Figure 2 As shown, a threaded column 14 is rotatably installed on the upper end of each supporting leg 15, and each supporting leg 15 is installed by matching the outer surface thread of the threaded column 14 with the groove below the connecting column 11. This structure can drive the supporting leg 15 to fit with the ground by rotating the threaded column 14 when in use, so that it can provide auxiliary support for the device after the height is adjusted, thereby improving the stability of the device.

[0021] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a reserved groove 12 is opened inside the support platform 1, the fixing plate 13 is installed in the upper half of the reserved groove 12, and the connecting plate 16 is installed in the lower half of the reserved groove 12. The reserved groove 12 cooperates with the fixing plate 13 to install the connecting plate 16 in the reserved groove 12 opened inside the support platform 1, so as to facilitate the installation of the device.

[0022] In this embodiment, Figure 1 and Figure 3 As shown, the four corners of the lower end of the connecting plate 16 are fixedly installed with a first rotating hub 17, and each of the first support rod 18 and the second support rod 19 is connected to the connecting plate 16 through the first rotating hub 17. This structure can adjust the height of the device through the cooperation between the first rotating hub 17, the first support rod 18, and the second support rod 19 and the subsequent auxiliary base 21 and other parts during use.

[0023] In this embodiment, Figure 1, Figure 3 and Figure 4 As shown, a sliding block 2 is rotatably installed at the lower end of each first support rod 18, and two limiting grooves 22 are provided at the upper end of the auxiliary base 21. Each first support rod 18 is slidably installed above the auxiliary base 21 through the cooperation of the sliding block 2 and the limiting groove 22. This structure can limit the sliding block 2 through the limiting groove 22 when in use, and support and adjust the connecting plate 16 by rotating the motor 24 and the second rotating hub 23 in cooperation with the first support rod 18 and the second support rod 19.

[0024] In this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, two second rotating hubs 23 are fixedly installed on the upper end of the auxiliary base 21, and the side end of each second rotating hub 23 is installed with the same rotating motor 24. Each second support rod 19 is connected to the auxiliary base 21 through the second rotating hub 23. This structure can quickly support or lower the device when in use, thereby facilitating the height adjustment of the device.

[0025] The use method and advantages of the utility model: When the support frame with height adjustment function is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, when using, the user places the device on a horizontal plane, picks up the supporting platform 1, installs the connecting columns 11 at the four corners below the supporting platform 1, then picks up the supporting legs 15, and installs the threaded columns 14 above the supporting legs 15, and then assembles the four supporting legs 15 and installs them below the connecting columns 11 along the threaded columns 14, and then the user installs the fixing plate 13 in the reserved groove 12 opened inside the supporting platform 1, and then installs the connecting plate 16 under the fixing plate 13, and then installs the first rotating pivot 17 at the four corners below the connecting plate 16, installs the second supporting rod 19 in the two first rotating pivots 17, and then installs the first supporting rod 18 in the other two first rotating pivots 17, and then installs the sliding block 2 under the two first supporting rods 18, and then the user picks up the auxiliary base 21, installs the two second rotating pivots 23 above the auxiliary base 21, and installs the rotating pivots 23 between the two second rotating pivots 23. The motor 24 is driven to connect them, and then the auxiliary base 21 is installed under the connecting plate 16, the sliding block 2 is installed in the limiting groove 22 opened above the sliding block 2, and the lower end of the second support rod 19 is connected to the second rotating hub 23. When the user needs to use the device, the user first starts the rotating motor 24, and the rotating motor 24 cooperates with the second rotating hub 23 to drive the two second support rods 19 to rotate. While the second support rod 19 rotates, it cooperates with the first rotating hub 17 and the connecting plate 16 to lift up part of the support platform 1 to adjust its height. After adjusting to the appropriate height, the user rotates the threaded column 14 to make the support leg 15 contact the ground again for auxiliary support. At this time, the first support rod 18 will also rise together with the second support rod 19 under the action of the limiting groove 22, the sliding block 2 and the first rotating hub 17, thereby keeping the device in a horizontal state while supporting the device after the height adjustment.
