Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically a 3D printing device with an adaptive support mechanism. Background Technology

[0002] A 3D printer is a tool for printing models of objects. With the development of technology, the applications of 3D printers are becoming increasingly widespread. It's a technology that uses a digital model file as a basis, employing powdered metal or plastic and other bondable materials to construct objects layer by layer. Previously used primarily in mold making and industrial design for model creation, it is now increasingly being used for the direct manufacturing of some products. Parts printed using this technology are already being used in high-value applications (such as hip joints, teeth, or some aircraft components). "3D printing" signifies the widespread adoption of this technology. 3D printing is typically achieved using a digital material printer.

[0003] There are currently no effective solutions to the problems in the relevant technologies.

[0004] 1. Existing 3D printing devices with adaptive support mechanisms lack well-adaptive components in their support mechanisms, resulting in the device only being able to support and fix one type of 3D printing device, thus reducing the practicality of the support mechanism. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a 3D printing device with an adaptive support mechanism to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A 3D printing device with an adaptive support mechanism includes a base, a printer body, and a fixing plate. The upper end of the base has a placement groove, the printer body is disposed inside the placement groove, the fixing plate is slidably connected to both ends of the placement groove, a second return spring is fixedly connected to one end of the fixing plate, a connecting rod is fixedly connected to one end of the fixing plate, support blocks are fixedly connected to both ends of the base, plastic clips are arranged in an internal circumferential array on the support blocks, and a fastening bolt is threaded onto one end of the support blocks.

[0008] A further improvement of this utility model is that: the front and rear inner walls of the placement groove are provided with sliding grooves, and the two sides of the fixing plate are fixedly connected with sliders, and the sliders and the sliding grooves are compatible.

[0009] A further improvement of this utility model is that the slider is slidably connected to the inside of the groove, and the fixing plate is slidably connected to the placement groove through the slider and the groove.

[0010] Using the above technical solution, the slider and groove in the solution can limit the position of the fixed plate, allowing the fixed plate to make linear sliding motion.

[0011] A further improvement of this utility model is that: the support block has an internal movable cavity, the plastic clip is located on one side of the inner wall of the movable cavity, the connecting rod is located at the center of the plastic clip arranged in a circumferential array, and the fastening bolt has an internal through groove that is compatible with the connecting rod.

[0012] Using the above technical solution, the connecting rod in this solution can slide inside the through groove.

[0013] A further improvement of this utility model is that: one end of the support block is provided with a threaded groove, the fastening bolt is threaded into the inside of the threaded groove, one end of the plastic clip is provided with a first sliding surface, and the inner side of one end of the fastening bolt is provided with a second sliding surface.

[0014] Using the above technical solution, the first and second sliding surfaces in this solution are used to rub against each other, so that the plastic clips arranged in the circumferential array move closer to each other under the friction and compression of the fastening bolts, clamping the connecting rod, thereby ensuring the stability of the fixing plate.

[0015] A further improvement of the present invention is that: a limiting block is fixedly connected to the front end of the base, a connecting push plate is slidably connected to the outer wall of the limiting block, a limiting groove is opened inside the connecting push plate, the connecting push plate is slidably connected to the outer wall of the limiting block through the limiting groove, and a limiting plate is fixedly connected to the front end of the limiting block.

[0017] A further improvement of this utility model is that a first reset spring is fixedly connected to the rear end of the connecting push plate, and the end of the first reset spring away from the connecting push plate is fixedly connected to the front end of the base.

[0018] Using the above technical solution, the first reset spring in the solution can drive the connecting push plate to perform a reset movement, so that the connecting push plate returns to its original position.

[0019] A further improvement of this utility model is that: wedge-shaped baffles are fixedly connected to both ends of the connecting push plate, and a wedge-shaped stop block is fixedly connected to the end of the connecting rod away from the fixed plate, and the positions of the wedge-shaped baffles and the wedge-shaped stop block are adapted to each other.

[0020] Using the above technical solution, the wedge baffle and the wedge block in the solution are used to rub against each other, so that the wedge block drives the fixed plate to move through the connecting rod under the thrust of friction, thereby facilitating the placement of the printer body inside the placement slot.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By placing the printer body in the placement slot, the second return spring can drive the fixing plate to perform a reset movement, so that the fixing plate fixes the printer body inside the placement slot. It can fix printer bodies of different sizes. In conjunction with rotating the fastening bolts, the plastic clips move closer together to clamp the connecting rod, thereby ensuring the stability of the fixing plate.

[0023] 2. By pushing the connecting push plate, the wedge baffle and the wedge block rub against each other, so that the wedge block moves the fixed plate through the connecting rod under the thrust of friction, thus making it easy to place the printer body into the placement slot and making it convenient for the staff to operate.
