[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] like Figures 1 to 4 As shown, where Figure 1 This is a schematic diagram of the overall structure of a long workpiece grinding and anti-collision receiving machine suitable for centerless grinders. Figure 2 This is a schematic diagram of the structure of the feeding V-wheel 9. Figure 3 This is a schematic diagram showing the installation position of the lifting inclined block 17. Figure 4 This is a schematic diagram of the structure of the left and right fixed plates 21. This utility model provides a long workpiece through-grinding anti-collision receiving machine suitable for centerless grinders: it includes a main body 1, an electrical control box 2, and auxiliary mechanisms. The auxiliary mechanisms include a receiving synchronous belt 6, a workpiece buffer plate 7, a feeding V-wheel 9, a positioning blocking plate 11, a lifting plate 18, a transition pad 19, a line height adjustment seat 20, left and right fixed plates 21, a full-material sensor 22, a synchronous belt drive motor 24, a wedge-shaped material-lifting assembly 8, a water receiving device, and a protective device. The water receiving device includes a first water receiving tray 13 and a second water receiving tray 23. The protective device includes a chain guard 10 and a V-wheel motor guard 12. This solution ensures that the workpiece is not damaged by impact or scratches, and also allows the ground workpieces to be sequentially received into the receiving machine. It is understood that the aforementioned solution can guarantee that the workpiece is not damaged by impact or scratches.
[0021] In this embodiment, an electrical control box 2 is installed on the main body 1 of the equipment. The electrical control box 2 is used to install electrical control components such as PLC. The frame of the main body 1 is welded from 50×50×4mm Q235 square tubing; the electrical control box 2 is installed inside; a height adjustment support assembly and a movable support assembly are provided at the bottom; the line mounting position is provided with a screw adjustment mechanism for the line height adjustment seat 20; the double-row synchronous belt mounting panel is provided with a horizontal moving guide rail, and the line distance can be adjusted by the overall adjustment handwheel 3; this facilitates the adjustment of the front and rear distance of the line. The corresponding detachable parts in this application are all connected by bolts, which are common in the prior art.
[0022] The receiving synchronous belt 6 is located on the top of the equipment body 1, near the full material sensor 22. The workpiece buffer plate 7 is located on the top of the equipment body 1 near the feeding side of the receiving synchronous belt 6. Multiple feeding V-wheels 9 are located on the bottom of the equipment body 1 near the workpiece buffer plate 7. The positioning blocking plate 11 is located on the discharge side of the multiple feeding V-wheels 9. The lifting plate 18 is connected to the output end of the lifting dual-shaft cylinder 14. Multiple transition pads 19 are detachably installed on the equipment body 1. The line height adjustment seat 20 is located on the end of the equipment body 1 away from the electrical control box 2. The left and right fixing plates 21 are symmetrically arranged. The full-material sensor 22 is electrically connected to the electrical control box 2 and located on the discharge side of the receiving synchronous belt 6, and the wedge-shaped top-feeding assembly 8 is electrically connected to the electrical control box 2 and located on the feed side of the receiving synchronous belt 6. The water receiving device and the protective device are respectively installed on the equipment body 1. The receiving synchronous belt 6 uses a T10 type 75mm wide baffle synchronous belt as the conveying medium. The double-row synchronous belt and synchronous pulley are both processed by double-row one-time molding and two-stage cutting to ensure that the synchronous belt and synchronous pulley can run synchronously. The workpiece buffer plate 7 and the transition pad 19 are both made of urethane rubber to ensure that the surface of the ground workpiece is not damaged or scratched during the conveying process. Multiple feeding V-wheels 9 are used to export and convey the ground workpiece. During the conveying process, the full-material sensor 22 is used to sense the fullness of the material. The lifting plate 18 is used to lift and distribute the material. The positioning baffle 11 is used to limit the workpiece during transport. Then, it facilitates the material distribution after the lifting plate 18 is lifted. After distribution, the workpiece rolls down the guide, and the top is limited by the workpiece buffer plate 7. Finally, the workpiece falls onto the receiving synchronous belt 6 for transport.
[0023] The wedge-shaped ejector assembly 8 uses the lifting dual-axis cylinder 14 as the driving force, and is equipped with lifting guide rods 15 and guide linear bearings 16 on both sides as a guiding mechanism to ensure its stability. The lifting output working surface is the lifting inclined block 17. The lifting inclined block 17 is made of bakelite, which ensures the strength of the lifting inclined block 17 without scratching the grinding workpiece, and also ensures that the lifting inclined block 17 is durable and not easily damaged.
[0024] The multiple feeding V-wheels 9 are made of POM material and employ a single-support structure with deep groove ball bearings. Power is provided by a double-row sprocket drive and a speed-regulating geared motor. This structure is used to achieve the feeding of parts via the transmission of the feeding V-wheels 9.
[0025] Secondly, the first water receiving tray 13 is located at the bottom of the equipment body 1 on the side away from the feeding V-wheel 9; the second water receiving tray 23 is located on both sides of the equipment body 1. The first water receiving tray 13 and the second water receiving tray 23 are used to collect water during the conveying of the workpiece.
[0026] Then, the chain guard 10 is disposed on the outside of the transmission chain of the feeding V-wheel 9; the V-wheel motor guard 12 is disposed on the outside of the synchronous belt drive motor 24 of the transmission sprocket of the transmission chain of the feeding V-wheel 9. The chain guard 10 and the V-wheel motor guard 12 are used to protect the transmission mechanism.
[0027] Furthermore, the main body 1 of the equipment is also equipped with an overall adjustment handwheel 3, a left-right adjustment handwheel 4, and a front-back adjustment handwheel 5. The corresponding handwheels are used for adjusting the equipment.
[0028] Finally, the dimensions of the workpiece to be ground, as described in the main body 1 of the equipment, are: length 300mm-1200mm, and diameter [missing information].
[0029] When using the long workpiece anti-collision receiving machine for centerless grinders according to this utility model, the device is first set on the discharge side of the grinder, and the discharge gap between the feeding V-wheel 9 and the grinding wheel of the grinder is matched to facilitate the direct feeding of the workpiece onto the feeding V-wheel 9 for conveying after grinding. Then, when the stop plate 11 abuts against the workpiece, the lifting double-axis cylinder 14 is activated to raise the lifting wedge block 17 to lift the workpiece, facilitating the conveying of the workpiece onto the receiving synchronous belt 6. When the full material sensor 22 detects the workpiece signal, the receiving synchronous belt 6 stops operating. This application uses chain-driven feeding V-wheel 9 for receiving and wedge-shaped lifting. The automated through-feed grinding material collection system, using a dual-row synchronous belt combined with a material collection method, achieves automated through-feed grinding material collection. The lifting inclined block 17 is made of bakelite, and the feeding V-wheel 9 ensures that the grinding workpiece is not scratched during the conveying process, ensuring that the grinding surface remains intact. The workpiece buffer plate 7 and the transition pad 19 are both made of urethane rubber, ensuring that the grinding workpiece surface is not bumped or scratched during the conveying process. The main feature of this application is that it ensures normal automated through-feed grinding material collection without bumping or scratching the surface of the parts, ensuring that the workpiece can be stored intact in the material collection device after grinding, thus ensuring that the workpiece is not bumped or scratched, and at the same time, it can sequentially collect the ground workpiece into the material collection machine.
[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
