Description

Technical Field

[0001] This utility model relates to a 3D printing device, and more particularly to a 3D printing device for forming molds for mining machinery parts. Background Technology

[0002] As 3D printing technology matures, its applications have expanded from printing plastic products to printing metal products. Mining machinery may require specific parts to adapt to specific working conditions in different working environments. 3D printing can be customized according to specific needs without the need for mold making, saving mold manufacturing costs and time. It can also meet the needs of small-batch, multi-variety parts production for mining machinery.

[0003] During printing, the height, left-right, and front-back positions of the print head need to be adjusted. A rotating disk needs to be set on the machine to rotate the print head to meet the printing requirements. However, due to the large size and weight of the parts printed by mining machinery, the existing solution of directly setting a rotating disk on the machine makes it difficult to unload the parts after printing. If hoisting is required, it cannot be done from the top due to the influence of the deposition head, thus making construction difficult. Utility Model Content

[0004] Addressing the shortcomings of existing 3D printing technologies in handling large-mass parts, which makes it difficult to unload and remove them from the machine, this invention provides a 3D printing device for forming molds of mining machinery parts.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A 3D printing device for forming molds of mining machinery parts includes a machine table with a table and a print head set on the machine table. The print head is driven by a moving mechanism to move horizontally and vertically. It also includes a track set on the machine table and extending to the left and right sides, and a traveling trolley set on the track. The machine table is equipped with a liftable rotary drive mechanism. A rotating disk is mounted on the traveling trolley. The bottom of the rotating disk is equipped with a sleeve with a non-circular insertion hole. The output end of the rotary drive mechanism matches the shape of the insertion hole.

[0007] Preferably, the insertion hole is a conical hole, and the output end of the rotating mechanism is a conical head that matches the shape of the conical hole.

[0008] Preferably, a leveling switch for positioning the traveling trolley is provided between the machine table and the traveling trolley.

[0009] Preferably, it also includes two synchronously driven telescopic cylinders, the output of which is provided with a mounting plate, and the rotary drive mechanism is a servo motor mounted on the mounting plate, the output shaft end of which is provided with a tapered head for engaging with the insertion hole.

[0010] Preferably, the moving mechanism includes a stand, a lead screw mechanism mounted on the stand for vertical drive, a mounting bracket mounted on the nut seat of the lead screw mechanism, two forward and backward slide rails on the left and right sides of the mounting bracket, two forward and backward sliders mounted on the forward and backward slide rails, left and right slide rails mounted on the two forward and backward sliders, and left and right sliders mounted on the left and right slide rails. The mounting bracket is provided with a set of forward and backward pulley drive assemblies and a set of left and right pulley drive mechanisms. The forward and backward sliders and the right slider are respectively fixed or clamped to the pulleys of the two sets of pulley drive mechanisms. The pulley drive assembly includes a motor, pulleys, and a synchronous belt. The motor drives the pulleys to rotate, thereby driving the synchronous belt to rotate. When the synchronous belt rotates, it drives the corresponding slider to move. The forward and backward pulley drive assembly includes two sets of pulleys and two synchronous belts, and the two pulleys on its rear side are connected by a synchronous shaft.

[0011] Preferably, the traveling trolley has a mounting hole in the middle, and a bearing is provided at the mounting hole. The rotating disk rotates and engages with the traveling trolley through the bearing.

[0012] As a preferred option, the trolley is also equipped with a support platform, on which support balls are rotatably embedded, providing multi-position support to the bottom surface of the rotating disc.

[0013] Preferably, the traveling trolley is equipped with a disc brake that clamps the track.

[0014] Compared with the prior art, the advantages of this utility model are as follows: This application sets a track and a traveling trolley on the machine base so that after printing is completed, the printed parts can be transported out from the side by the trolley for hoisting and transfer without interference with the print head; in addition, the print head can only move and adjust its position in the left, right, front, back and vertical directions, and a rotating disk is set on the traveling trolley. After being raised by a liftable motor under the machine base, it is inserted into the sleeve under the rotating disk to complete the docking and drive the rotating disk to rotate, so as to meet different needs in printing.

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0021] This embodiment mainly describes the title of the 3D printing device for forming molds of mining machinery parts, as follows:

[0022] 3D printing equipment for molding dies for mining machinery parts, such as Figure 1-5 As shown, the system includes a machine base 10 with a table and a print head 30 mounted on top of the machine base 10. The print head 30 is driven by a moving mechanism to move horizontally and vertically. It also includes a track 20 located on the table of the machine base 10 and extending to the left and right sides, and a traveling carriage 40 mounted on the track 20. The machine base 10 has a height-adjustable rotary drive mechanism inside. A rotating disk 50 is mounted on the traveling carriage 40, and a sleeve 501 with a non-circular insertion hole is located at the bottom of the rotating disk 50. The output end of the rotary drive mechanism matches the shape of the insertion hole. In this design, the deposition head mainly achieves height, left-right, and front-back position adjustments, while rotation is achieved by the rotating disk 50. The rotating disk 50 is mounted on the traveling carriage 40 and is driven by the height-adjustable rotary drive mechanism inside the machine base 10. When the traveling carriage 40 moves to the processing position, it stops, and the rotary drive mechanism is raised and inserted into the insertion hole at the bottom of the sleeve 501 to achieve a rotational connection. After connection, limit or rotational processing can be performed. Rotational processing is mainly used for printing circular workpieces, such as moving cones. The print head 30 can be a laser deposition head, which introduces metal powder into the deposition head and melts it with a laser to print it according to the shape of the model. After cooling and solidification, it becomes a rough part blank, which can then be further processed to obtain the required workpiece.

[0023] Preferably, the socket is a conical hole, and the output end of the rotating mechanism is a conical head that matches the shape of the conical hole. The conical head is a multi-faceted pyramid or frustum, and when it is inserted into the socket, the rotating disk 50 will automatically rotate to align it with the socket.

[0024] Preferably, a leveling switch for positioning the traveling trolley 40 is provided between the table surface of the machine tool 10 and the traveling trolley 40. The leveling switch includes a slotted photoelectric switch disposed at the bottom of the traveling trolley 40 and a baffle plate disposed on the table surface of the machine tool 10. When the slotted photoelectric switch moves with the traveling trolley 40, the slotted photoelectric switch is not obstructed, and the traveling trolley 40 moves normally. When the slotted photoelectric switch is obstructed by the baffle plate, its feedback signal controls the traveling trolley 40 to stop moving and brake to a stop.

[0025] Preferably, the system also includes two synchronously driven telescopic cylinders 601. The output of each telescopic cylinder 601 is provided with a mounting plate 602, and the rotary drive mechanism is a servo motor 603 mounted on the mounting plate 602. The output shaft end of the servo motor 603 is provided with a tapered head for engaging with the insertion hole. The telescopic cylinders 601 are used to drive the servo motor 603 to rise and fall, thereby inserting the tapered head into the insertion hole.

[0026] Preferably, the moving mechanism includes a support frame 101, a lead screw mechanism 103 mounted on the support frame 101 for vertical driving, a mounting bracket 102 mounted on the nut seat of the lead screw mechanism 103, two forward and backward slide rails 701 mounted on the left and right sides of the mounting bracket 102, two forward and backward sliders 702 mounted on the forward and backward slide rails 701, left and right slide rails 704 mounted on the two forward and backward sliders 702, and left and right sliders 705 mounted on the left and right slide rails 704. The system includes a set of forward-backward pulley drive assemblies 703 and a set of left-right pulley drive mechanisms. The forward-backward slider 702 and the right-right slider are fixed or clamped to the pulleys of the two sets of drive mechanisms, respectively. The pulley drive assembly 703 includes a motor, pulleys, and a synchronous belt. The motor drives the pulleys to rotate, thereby driving the synchronous belt to rotate. When the synchronous belt rotates, it moves the corresponding slider. The forward-backward pulley drive assembly 703 includes two sets of pulleys and two synchronous belts, with the two rear pulleys connected by a synchronous shaft 706. This design provides a specific structure for driving the printhead 30 to move vertically, horizontally, and vertically.

[0027] Preferably, the traveling trolley 40 has a mounting hole in the middle, and a bearing is provided at the mounting hole. The rotating disk 50 is rotatably engaged with the traveling trolley 40 through the bearing. The outer wall of the sleeve 501 at the bottom of the rotating disk 50 is connected to the inner ring of the bearing by an interference fit.

[0028] Preferably, the traveling trolley 40 is also equipped with a support platform, on which support balls are rotatably embedded, providing multi-position support to the bottom surface of the rotating disk 50. This design, by incorporating support balls, reduces friction between the ball and the rotating disk 50 through their rotation, thus ensuring its support.

[0029] Preferably, a disc brake is provided between the traveling trolley 40 and the track 20 to clamp the track 20. When positioning via the leveling switch, if a small deviation occurs, fine-tuning is performed using the following method: After braking, when the conical head rises, release the brake. After the conical head is fully inserted into the insertion hole, release the brake again. When the conical head rises, it will drive the traveling trolley 40 to adjust the left and right deviations, thereby ensuring the concentricity of the conical head and the rotating disc 50.

Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
