Description

Technical Field

[0001] This application relates to the field of CNC machine tool technology, specifically a palletizing and unloading assembly and a high-efficiency CNC machining center. Background Technology

[0002] CNC (Computer Numerical Control) machine tools are automated machine tools controlled by a program. This control system logically processes programs with control codes or other symbolic instructions, decodes them via a computer, and enables the machine tool to execute predetermined actions. Through cutting tools, it processes raw materials into semi-finished parts. Traditional machining involves manual operation of ordinary machine tools, where the machine tool is manually operated to cut metal, and the precision of the product is measured visually using calipers and other tools. Modern industry has long used computer-controlled machine tools. CNC machine tools can automatically process any product and component directly according to programs pre-programmed by technicians. This is what we call "CNC machining." CNC machining is widely used in all areas of mechanical processing, and it is a developing trend and an important and necessary technical means in mold processing.

[0003] After the CNC machine tool completes the processing of the workpiece, the workpiece is removed from the worktable and placed therefore, and then transported to a designated location. During the temporary placement, the workpiece is moved by mechanical means and stacked for storage, thereby reducing the floor space occupied by the workpiece.

[0004] If the workpieces are easy to transport later, they will be temporarily placed on a trolley. When the workpieces are heavy, the workpieces placed at the top of the trolley will cause the other end of the trolley to tilt due to their own weight, resulting in the instability of the trolley. Utility Model Content

[0005] The purpose of this application is to provide a palletizing and unloading component and a high-efficiency CNC machining center to solve the problem mentioned in the background art that when the workpiece is heavy, the workpiece placed first on the top end of the trolley will cause the other end of the trolley to tilt due to its own weight, resulting in the instability of the trolley.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] This utility model provides a palletizing and unloading assembly, including: a frame, an unloading mechanism, and a palletizing and placing mechanism. The unloading mechanism is disposed above the frame, and the palletizing and placing mechanism is disposed inside the frame. The palletizing and placing mechanism includes a limiting rail welded to both ends of the inner wall of the frame and a placement platform horizontally slidably connected inside the limiting rail. The placement platform is provided with casters around its bottom. The palletizing and placing mechanism also has a circular groove opened on the surface of the placement platform and a fixing plate fixed on the outer wall of the limiting rail. The fixing plate has an "L" shaped cross section and a vertical circular hole opened on the top of the fixing plate. The palletizing and placing mechanism also includes a connecting rod slidably connected inside the vertical circular hole of the fixing plate and a spring sleeved on the connecting rod. A baffle is integrally formed on the connecting rod, and the two ends of the spring are respectively attached to the outer walls of the baffle of the fixing plate and the connecting rod.

[0008] By adopting the above technical solution, the stability of the workpiece during the palletizing process can be improved.

[0009] Preferably, the feeding mechanism further includes a slide rail welded to the frame and a slider that is horizontally slidably connected inside the slide rail, and the slider has a toothed plate integrally formed on it.

[0010] By adopting the above technical solution, horizontal movement can be achieved, thereby allowing the subsequent structure at one end to be displaced synchronously.

[0011] Preferably, the feeding mechanism further includes a bidirectional motor fixed above the slide rail and gears connected to the output ends of the bidirectional motor on both sides by a shaft, and the gears mesh with the rack plate on the slider.

[0012] By adopting the above technical solution, during the rotation process, the meshing structure below can be driven to move horizontally in a synchronized manner.

[0013] Preferably, the feeding mechanism further includes a cylinder fixed above the slider and an electromagnet structure disposed on the output end of the cylinder.

[0014] By adopting the above technical solution, movement in the "Y" axis direction can be achieved, providing an electromagnet structure to hold and fix the workpiece.

[0015] In another aspect, this utility model also provides a high-efficiency CNC machining center, including a palletizing and unloading assembly as described in any of the above claims. The high-efficiency CNC machining center further includes an operation box, which is disposed on one side of the outer wall of the frame.

[0016] By adopting the above technical solution, the internal structure can be protected, and the workpiece can be shielded during the processing.

[0017] Preferably, the high-efficiency CNC machining center further includes: a movable worktable, which is located inside the control box and can move in the "X" and "Z" axis directions inside the control box.

[0018] By adopting the above technical solution, the position of the workpiece placed above can be adjusted by moving along the "X" and "Z" axes.

[0019] Preferably, the high-efficiency CNC machining center further includes: a machining structure, which is located inside the operating box and outside the movable worktable, and the machining structure consists of a "Y" axis lifting mechanism and a workpiece machining device on the "Y" axis lifting mechanism.

[0020] By adopting the above technical solution, the workpiece can be processed by moving the "Y" axis.

[0021] In summary, this application has the following beneficial effects: by providing a palletizing and placing mechanism, the limiting rail can prevent one end of the placing platform from tilting when the workpiece is placed on top of the placing platform, and by inserting the connecting rod into the circular groove above the placing platform, it can prevent the placing platform from shaking due to the weight of the workpiece when it is placed on top of the placing platform, thereby improving the accuracy of subsequent palletizing of the workpiece.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0029] Example 1

[0030] Please see Figures 1-4 This embodiment provides a technical solution: a palletizing and unloading assembly, including: a frame 1, an unloading mechanism 2, and a palletizing and placing mechanism 3;

[0031] Frame 1 provides an effective fixed connection for the internal structure. The feeding mechanism 2 is located above the frame 1 and can move the processed workpiece. The slide rail 201 is welded to the frame 1 and can move the internal structure horizontally. The slider 202 is horizontally slidably connected inside the slide rail 201. During the movement of the slider 202, it can synchronously drive the connected structure to move synchronously. The slider 202 has a toothed plate integrally formed on it, which can easily engage with the structure on the outer wall.

[0032] A bidirectional motor 203, fixed above the slide rail 201, is connected by bolts to provide rotation for the structure at its output end. Gears 204, connected to the output ends of the bidirectional motor 203 via shafts, continuously rotate when connected to the motor and mesh with a rack plate on the slider 202. During rotation, the gears 204 provide horizontal movement for the slider 202. A cylinder 205, fixed above the slider 202 and connected by bolts, drives the structure connected to its output end to move vertically. An electromagnet structure 206, energized at the output end of the cylinder 205, is a device that generates electromagnetism when energized. This electromagnet structure 206 is magnetic when energized and loses its magnetism when de-energized. This is existing technology and will not be described further below.

[0033] The palletizing and placement mechanism 3 is located inside the frame 1. This mechanism provides for the subsequent palletizing and placement of workpieces. The mechanism includes limiting rails 301 welded to both ends of the inner wall of the frame 1. These rails limit the movement of the internal structure, preventing it from tilting. A placement platform 302 is horizontally slidably connected inside the limiting rails 301. The platform 302 provides for the palletizing and placement of workpieces and facilitates their subsequent transport to a designated position. The platform 302 is equipped with casters around its bottom, allowing it to move horizontally on the ground. A circular groove 303 is formed on the upper surface of the platform 302, allowing external structures to be inserted into it for subsequent connection.

[0034] A fixing plate 304 is fixed on the outer wall of the limiting track 301. The fixing plate 304 is connected by bolts. The cross-sectional shape of the fixing plate 304 is "L" shaped, and a circular hole is opened inside the fixing plate 304. A connecting rod 305 is vertically slidably connected inside the fixing plate 304. The connecting rod 305 can be inserted into the circular groove 303 during movement. A baffle is integrally formed on the connecting rod 305. A spring 306 is sleeved on the connecting rod 305. The spring 306 can achieve the compression work through its own elasticity. The two ends of the spring 306 are respectively attached to the outer walls of the baffles of the fixing plate 304 and the connecting rod 305. The spring 306 drives the connecting rod 305 to move vertically by compression.

[0035] When the finished workpieces need to be stacked, the lifting connecting rod 305 is moved vertically upwards, moving the placement platform 302 into the limiting track 301 inside the frame 1. Then, the lifting of the connecting rod 305 is stopped, and the connecting rod 305 is squeezed by the spring 306 under the fixing plate 304, thereby moving the bottom end of the connecting rod 305 into the circular groove 303 above the placement platform 302, thus providing stability for the placement platform 302 when placing workpieces. Then, the cylinder 205 drives the electromagnet structure 206 to adhere to the surface of the workpiece, at which point the electromagnet structure 206 will attract the workpiece. The bidirectional motor 203 drives the gear 204 to rotate, thereby driving the slider 202 to move inside the slide rail 201 during the rotation of the gear 204, thereby synchronously moving the workpiece attracted by the electromagnet structure 206 onto the placement platform 302 for subsequent stacking.

[0036] Example 2

[0037] Please see Figures 1-3This embodiment provides a technical solution: a palletizing and unloading assembly, including: an operation box 4, a movable workbench 5, and a processing structure 6;

[0038] The operating box 4 is located on one side of the outer wall of the frame 1. The operating box 4 can effectively shield the workpiece being processed inside, preventing debris from flying. The movable worktable 5 is located inside the operating box 4. A clamping block is provided above the movable worktable 5 to fix the workpiece. The movable worktable 5 can move in the "X" and "Z" axis directions inside the operating box 4, allowing the fixed workpiece to move in the "X" and "Z" axis directions. The processing structure 6 is located outside the movable worktable 5, and the processing structure 6 consists of a "Y" axis lifting mechanism and a workpiece processing device on the "Y" axis lifting mechanism. It can cooperate with the "X" and "Z" axis movement of the movable worktable 5 to perform multi-position processing on the workpiece.

[0039] The workpiece is placed on the movable worktable 5, which clamps and fixes the workpiece. The movable worktable 5 drives the workpiece to move in the "X" and "Z" axis directions, and cooperates with the movement of the machining structure 6 in the "Y" axis direction, so that the workpiece can be effectively machined at various positions.

[0040] The implementation principle of the palletizing and unloading component and high-efficiency CNC machining center of this application is as follows:

[0041] First, the workpiece is placed on the movable worktable 5, which clamps and fixes the workpiece. The movable worktable 5 drives the workpiece to move in the "X" and "Z" axis directions, and in conjunction with the movement of the machining structure 6 in the "Y" axis direction, the workpiece can be effectively machined at various positions.

[0042] Secondly, when the finished workpieces need to be stacked, the lifting connecting rod 305 is moved vertically upwards, at which point the placement platform 302 is moved into the limiting track 301 inside the frame 1. Then the connecting rod 305 is no longer lifted. At this time, the connecting rod 305 is squeezed by the spring 306 under the fixing plate 304, thereby driving the bottom end of the connecting rod 305 to move into the circular groove 303 above the placement platform 302, thus providing stability for the placement platform 302 when placing workpieces.

[0043] Finally, the cylinder 205 drives the electromagnet structure 206 to adhere to the surface of the workpiece. At this time, the electromagnet structure 206 will attract the workpiece. The bidirectional motor 203 drives the gear 204 to rotate. During the rotation of the gear 204, the slider 202 moves inside the slide rail 201, thereby synchronously moving the workpiece attracted by the electromagnet structure 206 to the placement table 302 for subsequent stacking.

[0044] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
