Description

Technical Field

[0001] This utility model relates to the field of valve guide manufacturing technology, specifically to an automatic feeding device for valve guide grinding machines. Background Technology

[0002] The function of the valve guide is to guide the movement of the valve, ensuring that the valve performs reciprocating linear motion, allowing the valve and valve seat to fit correctly, and transferring the heat of the valve stem to the cylinder head. The valve guide operates at a relatively high temperature, approximately 200°C. As the valve stem moves within the guide, it is only lubricated by engine oil splashed from the valve train, making it prone to wear. Therefore, most valve guides are made as separate parts using self-lubricating materials such as ductile iron or powder metallurgy.

[0003] Valve guides made by powder pressing have uneven or rough surfaces. To ensure high precision and performance, they need to be precision-machined using a grinding machine in subsequent processes. Currently, the loading of valve guides into the grinding machine is done manually, with each frame of products being lifted and then poured into the grinding machine's tray. This is labor-intensive, and the valve guides are prone to damage due to impacts during the tilting process. Summary of the Invention

[0004] This utility model provides an automatic feeding device for a valve guide grinding machine. By setting up a feeding machine between the outlet of the loading trolley and the inlet of the grinding machine's material tray, and setting a force-relieving component at the outlet of the feeding machine, the feeding machine conveys the material transported by the loading trolley to the grinding machine's material tray, and the force-relieving component absorbs the impact force of the material when it falls. Therefore, it can reduce the labor intensity of workers, improve production efficiency, and reduce the risk of workpiece damage.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An automatic feeding device for a valve guide grinding machine includes:

[0007] Loading trolley;

[0008] Grinding machine tray, the grinding machine tray being disposed on a grinding machine; and

[0009] The feeding machine is located between the outlet of the loading trolley and the inlet of the grinding machine tray, and is used to feed materials to the grinding machine tray. The outlet of the feeding machine is equipped with a force-relieving component that is activated by the falling force of the material to allow it to fall.

[0010] Preferably, the loading trolley includes a trolley frame, a loading bin located on top of the trolley frame, and a trolley bin door located at the outlet.

[0011] Preferably, the bottom of the trolley frame is equipped with casters.

[0012] Preferably, the outlet of the self-loading trolley of the feeding machine is inclined upward towards the feed inlet of the grinding machine's material tray.

[0013] Preferably, the feeder is a stepped feeder, and the feeder is also equipped with a speed control knob for adjusting the feeding speed.

[0014] Preferably, the feeder is equipped with a workpiece sensor at the discharge port for sensing whether there is material in the grinding machine tray.

[0015] Preferably, the unloading component includes two baffles that are rotatably connected to the discharge port of the feeder.

[0016] As can be seen from the above technical solutions, this utility model has the following beneficial effects:

[0017] 1. In this utility model, by setting up a feeding machine, the feeding machine is used to deliver valve guides to the grinding machine when the grinding disc of the material bed is short of material, thereby avoiding the need to manually lift each frame of products and then pour them into the grinding disc of the grinding machine, so as to reduce the labor intensity of workers and improve production efficiency; at the same time, a force relief component is set at the discharge port of the feeding machine, which can be used to open the force relief component when the valve guide is unloaded by gravity, thereby avoiding excessive impact force from damaging the valve guide and preventing product damage.

[0018] 2. In this utility model, the feeding machine is also equipped with a speed adjustment knob for adjusting the feeding speed. The speed adjustment knob can be connected to the drive motor of the feeding machine to adjust the feeding speed so as to match the production rhythm and further improve production efficiency.

[0019] 3. In this utility model, a workpiece sensor is provided at the discharge port of the feeder to sense whether there is material in the grinding machine tray. The workpiece sensor is used to sense whether there is material and how much material is in the grinding machine tray. When there is insufficient workpiece in the grinding machine tray, the feeder can be activated to lift the valve guide into the grinding machine tray. Therefore, the working status of the feeder can be controlled according to the actual production needs, which can further improve production efficiency and meet production requirements.

[0025] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: (Refer to...) Figure 1 An automatic feeding device for a valve guide grinding machine includes a loading trolley 10, a grinding machine material tray 20, and a feeder 30. The grinding machine material tray 20 is mounted on the grinding machine. The feeder is positioned between the outlet of the loading trolley 10 and the inlet of the grinding machine material tray 20, for feeding material into the grinding machine material tray 20. Furthermore, the feeder 30 has a force-relieving component at its outlet that is opened by the falling force of the material. In use, the pressed and formed valve guide is placed inside the loading trolley 10. When the outlet of the loading trolley is opened, the valve guide automatically slides down to the bottom of the feeder for storage. Within the material handling area, valve guides can then be fed to the grinding machine's material tray via a feeder for precision machining. This invention utilizes a feeder to deliver valve guides to the grinding machine when the material tray is low on material, thus avoiding the need for manual lifting of each frame of products before dumping them into the grinding machine's material tray. This reduces labor intensity and increases production efficiency. Simultaneously, a force-relieving component is installed at the feeder's outlet. This component opens when the valve guides are unloaded using gravity, preventing excessive impact from damaging the valve guides and protecting the products from injury.

[0027] Reference Figure 2 As a preferred technical solution in this embodiment, the loading trolley 10 includes a trolley frame 110, a loading bin 120, and a trolley bin door 130. Further, the loading bin 120 is located at the top of the trolley frame, the outlet is located at the bottom of the loading bin 120, and the trolley bin door 130 is located at the outlet of the loading trolley 10. In this way, the loading bin 120 can be unloaded by opening the trolley bin door 130. It should be noted that the loading bin 120 has a bucket-shaped structure that is wider at the top and narrower at the bottom. The loading bin 120 is used to store valve guides to be processed by the grinding machine. When it is necessary to deliver valve guides to the grinding machine, the material can be automatically slid down onto the feeding machine through the outlet by opening the trolley bin door 130.

[0028] Furthermore, in order to facilitate the movement of the loading trolley 10, casters 140 are provided at the bottom of the trolley frame 110. During operation, the loading trolley 10 can be moved to a suitable position by moving the casters, so as to load the grinding machine.

[0029] Reference Figure 3 , Figure 4 In some embodiments, the feeder 30 is inclined upward from the outlet of the self-loading trolley 10 towards the feed inlet of the grinding machine tray 20. In this case, the valve guide in the self-loading trolley 10 can be lifted upward into the grinding machine tray 20. Of course, the feeder 30 is not limited to being inclined upward; other configurations are also possible, as long as the self-loading trolley 10 can deliver the valve guide to the grinding machine tray 20.

[0030] Furthermore, the feeder 30 is a stepped feeder, which is an automated material handling equipment widely used in industrial production, especially in the field of pipe fitting processing. The stepped feeder automatically transports materials from one place to another, which can improve production efficiency and reduce labor costs.

[0031] Furthermore, the feeder is also equipped with a speed control knob 310 for adjusting the feeding speed. The speed control knob 310 can be connected to the drive motor of the feeder to adjust the feeding speed in order to match the production rhythm and further improve production efficiency.

[0032] Furthermore, the feeder 30 is equipped with a workpiece sensor at the discharge port for sensing whether there is material in the grinding machine tray 20. The workpiece sensor is used to sense whether there is material in the grinding machine tray and how much there is. When there is insufficient workpiece in the grinding machine tray, the feeder can be activated to lift the valve guide upward into the grinding machine tray 20.

[0033] In some embodiments, the unloading assembly includes two baffles 320 rotatably connected to the discharge port of the feeder 30. Further, the baffles are made of resin material, so that when the valve guide falls through the discharge port, it will first contact the baffles. Since the baffles are rotatably set on the discharge port and the material of the baffles is soft, the gravity of the falling valve guide will drive the baffles on both sides to open to realize the opening of the discharge port, so that the material conveyed by the feeder can fall into the grinding machine tray. At the same time, since the baffles are relatively soft, the valve guide will not be damaged when it contacts the baffles, reducing the risk of valve guide impact.

[0034] In use, the valve guide to be precision-machined by the grinding machine is placed in the loading trolley 10. When the loading trolley 10 opens the lower trolley door 130, the valve guide automatically slides down to the storage area at the bottom of the feeder 30. When the workpiece sensor detects that there are not enough workpieces in the grinding machine tray 20, the feeder 30 starts to work, conveying the valve guide upwards to the grinding machine tray 20. Since a baffle 320 is set at the discharge port of the feeder 30, the impact force of the workpiece falling into the grinding machine tray 20 can be buffered to avoid damage to the valve guide and reduce the risk of valve guide collision. At the same time, the feeder 30 is also equipped with a speed adjustment knob 310 for adjusting the feeding speed, which can be used to match the production rhythm to further improve production efficiency.

[0035] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
