Description

Technical Field

[0001] This utility model specifically relates to the field of processing equipment technology, and more specifically to a frame processing device for a 3D printer. Background Technology

[0002] There are several ways to process the frame of a printer. Traditionally, stamping or die casting is used. While this can achieve the desired frame shape, the surface of the frame is relatively rough. Furthermore, welding is required to assemble the frames, which results in low production efficiency and makes it difficult to guarantee the assembly accuracy between the frames.

[0003] To address the above issues, we provide a frame processing device for 3D printers. In this device, the frame to be processed is placed on a model table, and the edges of the frame are processed in one go using a processing tool. The movement of the processing tool enables the frame edges to be shaped in one go, ensuring processing accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a frame processing device for 3D printers. The frame to be processed is placed on a model table, and the model table provides internal support for the frame. Then, an electric pusher cylinder drives the push rod to retract, so that the pressure plate at the top of the push rod fits against the inner edge of the frame. This effectively fixes the frame on the model table without obstructing the processing edge of the frame, ensuring that the processing tool can process the frame in one go, thus guaranteeing the processing quality and accuracy of the frame and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A frame processing device for a 3D printer includes a movable clamping assembly comprising a carrier plate; a model stage is integrally mounted on the carrier plate; the edge of the model stage is fitted against the inner wall of the frame; a circular hole is provided at the center of the carrier plate and the model stage to facilitate the passage of a push rod of an electric push cylinder; the side of the carrier plate away from the model stage is fixedly installed with a vertical plate; two vertical plates are provided and symmetrically arranged; grooves are provided on the vertical plates to facilitate the contact of pressure blocks; the pressure blocks are detachably installed with a pad and a sliding plate; the frame is placed on the edge of the model stage, with the bottom of the frame fitted against the carrier plate, thus effectively ensuring that the frame will not loosen after being fixed during processing, effectively guaranteeing the processing accuracy of the frame;

[0007] The slide plate has two integrally formed semicircular blocks at its bottom, each of which is slidably mounted to a guide rod. One of the semicircular blocks is fixedly mounted to a slide frame. The end of the slide frame away from the semicircular block is fitted with a first lead screw. Both ends of the first lead screw are fixedly mounted to the base via bearing seats. One end of the first lead screw is fixedly mounted to a first drive motor. The first drive motor drives the first lead screw to rotate, thereby moving the slide frame and the slide plate, moving the frame to be processed to the processing position, reducing the travel of the processing tool, and improving work efficiency.

[0008] As a further technical solution of this utility model, both ends of the two guide rods are fixedly mounted on the base plate by bearings with seats; a rectangular groove is provided on the base plate, and the bearings with seats for mounting the guide rods are mounted on both ends of the rectangular groove; during the movement of the slide, it moves along the two guide rods, effectively ensuring that the frame on the carrier plate will not shift during the movement, and ensuring that the machining tool is positioned correctly.

[0009] As a further technical solution of this utility model, an electric push cylinder is fixedly installed at the bottom of the skateboard; the push rod of the electric push cylinder passes through the skateboard, the carrier plate and the model platform; a pressure plate is fixedly installed at the top of the push rod of the electric push cylinder; the pressure plate is in contact with the frame; by driving the push rod to retract through the electric push cylinder, the pressure plate at the top of the push rod is in contact with the protruding plate inside the frame, and the pressure plate effectively fixes the frame by cooperating with the model platform.

[0010] As a further technical solution of this utility model, a transverse moving component is fixedly installed at one end of the base; the transverse moving component includes two symmetrically arranged support plates; a second lead screw is arranged between the two support plates; guide slides are arranged on both sides of the second lead screw; one end of the second lead screw is fixedly installed with a second drive motor; the second drive motor is fixedly installed with one of the support plates; a transverse slide is fitted on the second lead screw and the two guide slides; a longitudinal slide is fitted on the transverse slide. The second lead screw is driven to rotate by the second drive motor to realize the transverse movement of the machining tool, and the longitudinal slide is driven to move the machining tool longitudinally by the rotation of the electric lead screw inside the longitudinal slide, thereby meeting the different needs of the machining tool during the machining process.

[0011] As a further technical solution of this utility model, the longitudinal slide table is installed with the bottom of the longitudinal slide frame through a slide rail and a slider;

[0012] As a further technical solution of this utility model, a vertical moving component is fixedly installed at one end of the longitudinal slide; the vertical moving component includes a U-shaped frame fixedly installed with the longitudinal slide; the U-shaped frame is vertically arranged, and a vertical lead screw is installed inside the U-shaped frame; one end of the vertical lead screw is fixedly installed with a third drive motor; the vertical lead screw is installed through a vertical sliding plate; a machining tool is fixedly installed on the side of the vertical sliding plate away from the U-shaped frame; when the machining tool needs to perform different depth machining on the frame, the vertical lead screw is driven to rotate by the third drive motor, so that the vertical sliding plate moves up and down along the U-shaped frame to meet the machining needs of the machining tool.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In use, the two upright plates are first fixed to the slide plate by pressure blocks, then the carrier plate and the model platform are fixedly installed on the upright plates, and the electric push cylinder is fixedly installed at the bottom of the slide plate. The push rod of the electric push cylinder passes through the slide plate, the carrier plate and the model platform. A pressure plate is fixedly installed at the top of the push rod of the electric push cylinder. Through the cooperation of the pressure plate and the model platform, the frame is effectively clamped and fixed.

[0015] 2. In this utility model, the two ends of the pressure plate fit into the protruding positions on the inner side of the frame, which effectively avoids obstructing the outer edge of the frame and ensures that the processing tool moves along the edge of the frame as a whole during the processing, thus ensuring the processing quality and efficiency of the frame.

[0016] 3. In this utility model, during processing, the slide plate moves along the guide rod to the bottom of the processing tool via the slide frame, which effectively reduces the stroke of the processing tool;

[0017] 4. In this utility model, when the position of the machining tool needs to be moved during the processing, the second drive motor drives the second lead screw to rotate, thereby enabling the transverse slide on the second lead screw and guide slide to move laterally. This allows the longitudinal slide to drive the longitudinal slide and vertical moving assembly to move laterally, meeting the needs of the machining tool. When the machining tool needs to move longitudinally, the longitudinal slide drives the vertical moving assembly to move back and forth, allowing the machining tool to process different positions of the frame. When the machining tool needs to process the frame to different depths, the third drive motor drives the vertical lead screw to rotate, enabling the vertical slide to slide up and down along the edge of the U-shaped frame, meeting the processing needs of the machining tool.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7In this embodiment of the present invention, a frame processing device for a 3D printer includes a movable clamping assembly 2, which includes a carrier plate 24. A model platform 25 is integrally mounted on the carrier plate 24. The edge of the model platform 25 is fitted to the inner wall of the frame 7. A circular hole is provided at the center of the carrier plate 24 and the model platform 25 to facilitate the passage of the push rod of the electric push cylinder 210. The side of the carrier plate 24 away from the model platform 25 is fixedly installed with a vertical plate 27. Two vertical plates 27 are provided and are arranged symmetrically. A groove is provided on the vertical plate 27 to facilitate the fitting of pressure blocks 211. The pressure blocks 211 are detachably installed with a sliding plate 21 via pads. Through the cooperation of the two pressure blocks 211 and the two vertical plates, the stability of the carrier plate 24 and the model platform 25 during the processing is effectively guaranteed.

[0028] The bottom of the slide plate 21 has two semi-circular blocks integrally formed, and the semi-circular blocks are slidably installed with two guide rods 26 respectively; one of the two semi-circular blocks is fixedly installed with the slide frame 28; the end of the slide frame 28 away from the semi-circular block is fitted with the first lead screw 22; the two ends of the first lead screw 22 are fixedly installed on the base 1 by bearings with seats; one end of the first lead screw 22 is fixedly installed with the first drive motor 23.

[0029] More specifically, both ends of the two guide rods 26 are fixedly mounted on the base plate 20 by bearings with seats; the base plate 20 is provided with a rectangular groove, and the bearings with seats for the guide rods 26 are installed at both ends of the rectangular groove. The rectangular groove on the slide plate 21 effectively avoids the bottom of the electric push cylinder 210 from being blocked during the sliding process, ensuring smooth processing and sliding above the slide plate 21.

[0030] By adopting the above technical solution, in use, firstly, the two upright plates 27 are fixed to the slide plate 21 by the pressure block 211, then the carrier plate 24 and the model platform 25 are fixedly installed on the upright plates 27, the electric push cylinder 210 is fixedly installed at the bottom of the slide plate 21, and the push rod of the electric push cylinder 210 passes through the slide plate 21, the carrier plate 24 and the model platform 25. A pressure plate 29 is fixedly installed at the top of the push rod of the electric push cylinder 210. Through the cooperation of the pressure plate 29 and the model platform 25, the frame 7 is effectively clamped and fixed.

[0031] An electric push cylinder 210 is fixedly installed at the bottom of the slide plate 21; the push rod of the electric push cylinder 210 passes through the slide plate 21, the carrier plate 24 and the model platform 25; a pressure plate 29 is fixedly installed at the top of the push rod of the electric push cylinder 210; the pressure plate 29 is in contact with the frame 7.

[0032] In this embodiment, a transverse moving component 3 is fixedly installed at one end of the base 1; the transverse moving component 3 includes two symmetrically arranged support plates 30; a second lead screw 33 is arranged between the two support plates 30; guide slides 32 are arranged on both sides of the second lead screw 33; one end of the second lead screw 33 is fixedly installed with a second drive motor 31; the second drive motor 31 is fixedly installed with one of the support plates 30; a transverse slide 34 is fitted on the second lead screw 33 and the two guide slides 32; a longitudinal slide 35 is fitted on the transverse slide 34.

[0033] By adopting the above technical solution, the two ends of the pressure plate 29 are fitted with the protruding positions on the inner side of the frame 7, which effectively avoids blocking the outer edge of the frame 7 and effectively ensures that the processing tool 40 moves along the edge of the frame 7 as a whole during the processing, thus ensuring the processing quality and efficiency of the frame 7.

[0034] Furthermore, during machining, the slide plate 21 moves along the guide rod 26 via the carriage 28 to the bottom of the machining tool 40, which effectively reduces the stroke of the machining tool 40;

[0035] In this embodiment, the longitudinal slide table 35 is installed in conjunction with the bottom of the longitudinal slide frame 5 via a slide rail and a slider;

[0036] A vertical moving component 6 is fixedly installed at one end of the longitudinal slide 5; the vertical moving component 6 includes a U-shaped frame 60 fixedly installed with the longitudinal slide 5; the U-shaped frame 60 is vertically arranged, and a vertical lead screw 62 is installed inside the U-shaped frame 60; one end of the vertical lead screw 62 is fixedly installed with a third drive motor 61; the vertical lead screw 62 is installed through a vertical sliding plate 41; a machining tool 40 is fixedly installed on the side of the vertical sliding plate 41 away from the U-shaped frame 60.

[0037] By adopting the above technical solution, when the position of the machining tool 40 needs to be moved during the processing, the second drive motor 31 drives the second lead screw 33 to rotate, so that the second lead screw 33 and the transverse slide 34 on the guide slide rod 32 can move laterally, so that the longitudinal slide 35 drives the longitudinal slide 5 and the vertical moving component 6 to move laterally, thus meeting the needs of the machining tool 40. When the machining tool 40 needs to move longitudinally, the longitudinal slide 5 drives the vertical moving component 6 to move back and forth, thus meeting the processing needs of the machining tool 40 at different positions of the frame 7. When the machining tool 40 needs to process the frame 7 at different depths, the third drive motor 61 drives the vertical lead screw 62 to rotate, so that the vertical slide 41 reaches the top and the machining tool 40 slides up and down along the edge of the U-shaped frame 60, thus meeting the processing needs of the machining tool 40.

[0038] As a further explanation of the above embodiments: each motor, electric actuator and other drive element is controlled by a controller; the operating program is set by various parameters of the product and processing requirements, and is uniformly controlled by the controller; the controller can be Siemens S7-1200 / 1500 or Mitsubishi FX5U.

[0039] Controlling the coordinated operation of various driving components through a controller is an existing technology, and its specific principles will not be elaborated here.

[0040] The working principle of this utility model is as follows: In use, firstly, two upright plates 27 are fixed to the slide plate 21 by pressure blocks 211. Then, the carrier plate 24 and the model platform 25 are fixedly installed on the upright plates 27. The electric push cylinder 210 is fixedly installed at the bottom of the slide plate 21, and the push rod of the electric push cylinder 210 passes through the slide plate 21, the carrier plate 24 and the model platform 25. A pressure plate 29 is fixedly installed at the top of the push rod of the electric push cylinder 210. Through the cooperation of the pressure plate 29 and the model platform 25, the frame 7 is effectively clamped and fixed.

[0041] The two ends of the pressure plate 29 are fitted with the protruding positions on the inner side of the frame 7, which effectively avoids obstructing the outer edge of the frame 7 and ensures that the machining tool 40 moves along the edge of the frame 7 as a whole during the machining process, thus ensuring the machining quality and efficiency of the frame 7.

[0042] During machining, the slide plate 21 moves along the guide rod 26 via the carriage 28 to the bottom of the machining tool 40, which effectively reduces the stroke of the machining tool 40;

[0043] During the machining process, when the position of the machining tool 40 needs to be moved, the second drive motor 31 drives the second lead screw 33 to rotate, thereby enabling the second lead screw 33 and the transverse slide 34 on the guide slide 32 to move laterally. This enables the longitudinal slide 35 to drive the longitudinal slide 5 and the vertical moving assembly 6 to move laterally, thus meeting the needs of the machining tool 40. When the machining tool 40 needs to move longitudinally, the longitudinal slide 5 drives the vertical moving assembly 6 to move back and forth, thus meeting the machining tool 40's machining needs at different positions on the frame 7. When the machining tool 40 needs to machine the frame 7 to different depths, the third drive motor 61 drives the vertical lead screw 62 to rotate, enabling the vertical slide plate 41 to reach the top and the machining tool 40 to slide up and down along the edge of the U-shaped frame 60, thus meeting the machining needs of the machining tool 40.
