Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to a multi-station micro-hole polishing machine. Background Technology

[0002] Fluid polishing is a process that uses a fluid medium (such as abrasive slurry, gas, or magnetic fluid) to precisely grind the surface of a workpiece. It is suitable for ultra-precision machining of complex geometries, internal cavities, and microstructures. Abrasive Flow Machining (AFM) involves forcing a viscoelastic abrasive slurry (silicone + abrasive grains) through the internal cavity or surface of the workpiece under high pressure, using the cutting action of the abrasive grains to remove burrs and polish the surface. Existing polishing equipment for microporous workpieces is mostly single-station polishing, meaning that polishing cannot be performed simultaneously during product loading and unloading, affecting polishing efficiency. Furthermore, the abrasive recovery system is often inadequate, failing to achieve sufficient collection and recirculation of the abrasive. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a multi-station micro-hole polishing machine that can realize automatic feeding, polishing and unloading of products. Moreover, by adopting multiple stations, the polishing of products does not affect the feeding of unpolished products and the unloading of polished products, which greatly improves the production efficiency of the equipment.

[0004] To solve the above-mentioned technical problems, the present invention provides a multi-station micro-hole polishing machine, including a machine base, a rotatable turntable, an abrasive supply system, an abrasive recycling system, a mold closing device, a material unloading device, and a collection area. The turntable is installed on the machine base and has multiple stations, including a material loading station, a polishing station, and a material unloading station. Each station is equipped with a tooling for placing products.

[0005] The mold clamping device includes a clamping head and a mold clamping lifting drive unit. The clamping head is installed on the power output end of the mold clamping lifting drive unit, and the clamping head is driven to rise and fall by the mold clamping lifting drive unit. The discharge port of the abrasive supply system is connected to the discharge channel of the clamping head.

[0006] The abrasive recovery system is connected to the abrasive supply system via a switching valve;

[0007] The unloading device includes a material-picking gripper, a material-picking and mold-closing lifting drive unit, and a material-picking and translation drive unit. The material-picking gripper is installed on the power output end of the material-picking and translation drive unit, and the material-picking gripper is driven by the material-picking and translation drive unit to reciprocate between the collection area and the unloading station.

[0008] Furthermore, the turntable is also equipped with a sensor for detecting the presence of a product.

[0009] Furthermore, the collection area is an inclined trough with one end higher than the other; a collection trough is provided below the feeding device.

[0010] Furthermore, the surface of the machine tool is provided with a perforated grid plate, and the abrasive recovery system includes a receiving funnel, a first abrasive recovery pipe, an abrasive recovery hopper, and a second abrasive recovery pipe. The receiving funnel is located directly below the polishing station. The cavity between the grid plate and the machine tool is connected. The two ends of the first abrasive recovery pipe are respectively connected to the receiving funnel and the abrasive recovery hopper. The two ends of the second abrasive recovery pipe are respectively connected to the cavity and the abrasive recovery hopper. The abrasive recovery hopper is connected to a switching valve.

[0011] Furthermore, the abrasive supply system includes an abrasive cylinder, an extrusion cylinder, and an extrusion piston. The extrusion piston is installed at the end of the push rod of the extrusion cylinder and is located inside the abrasive cylinder. The abrasive cylinder is connected to the switching valve. The switching valve is also connected to one end of the abrasive feed pipe, and the other end of the abrasive feed pipe is connected to the discharge channel of the pressing head.

[0013] Furthermore, the workstation also includes a spare workstation located between the polishing workstation and the loading workstation.

[0014] The beneficial effects of this utility model are:

[0015] This invention is designed for polishing products with tiny internal holes. Unpolished products are placed at the loading station. After automatic startup, the products rotate to the polishing station, where a mold-closing device closes and presses the products for polishing. After polishing, the mold-closing device automatically releases, and the polished products rotate to the unloading station. The unloading device picks up the products and places them in the collection area. This system enables automatic loading, polishing, and unloading of products. Furthermore, the multi-station design ensures that polishing does not affect the loading of unpolished products or the unloading of polished products, significantly improving the equipment's production efficiency.

[0016] Furthermore, the abrasive can be collected and reused through an abrasive recycling system, and can also be combined with automated loading and unloading to improve the automation level of the entire equipment.

[0025] Product 100. Detailed Implementation

[0026] The following specific embodiments illustrate the detailed implementation of this utility model. Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0027] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this utility model.

[0028] Example: A multi-station micropore polishing machine, such as Figures 1 to 5As shown, the device includes a machine base 1, a rotatable turntable 2, an abrasive supply system 8, an abrasive recycling system 7, a mold clamping device 3, a material unloading device 4, and a collection area 5. The turntable is installed on the machine base and has multiple workstations, including a material loading workstation 21, a polishing workstation 22, and a material unloading workstation 23. Each workstation is equipped with a tooling 24 for placing the product 100.

[0029] The mold clamping device 3 includes a clamping head 31 and a mold clamping lifting drive unit 32. The clamping head is installed on the power output end of the mold clamping lifting drive unit, and the clamping head is driven to lift and lower by the mold clamping lifting drive unit. The discharge port of the abrasive supply system is connected to the discharge channel of the clamping head.

[0030] The abrasive recovery system is connected to the abrasive supply system via a switching valve 6;

[0031] The unloading device 4 includes a material-picking gripper 41, a material-picking and mold-closing lifting drive unit 42, and a material-picking and translation drive unit 43. The material-picking gripper is installed on the power output end of the material-picking and translation drive unit, and the material-picking gripper is driven by the material-picking and translation drive unit to reciprocate between the collection area and the unloading station.

[0032] In this embodiment, the turntable is also equipped with a sensor 26 for sensing whether a product is present at the workstation.

[0033] In this embodiment, the collection area is an inclined trough with one end higher than the other; a collection trough 44 is provided below the feeding device. The collection area is used to collect products. The feeding device places the product at one end of the collection area, and the product will automatically flow down, facilitating product collection. The collection trough is located below the position through which the picking gripper moves, and is used to collect abrasive that may drip from the product during movement. Because the polishing medium of this polishing machine is a fluid, abrasive will adhere to the product after polishing and may drip down.

[0034] In this embodiment, the surface of the machine tool is provided with a perforated grid plate 11. The abrasive recovery system 7 includes a receiving funnel 71, a first abrasive recovery pipe 72, an abrasive recovery funnel 73, and a second abrasive recovery pipe 74. The receiving funnel is located directly below the polishing station. The cavity between the grid plate and the machine tool is connected. The two ends of the first abrasive recovery pipe are respectively connected to the receiving funnel and the abrasive recovery funnel. The two ends of the second abrasive recovery pipe are respectively connected to the cavity and the abrasive recovery funnel. The abrasive recovery funnel is connected to a switching valve. For example, the bottom of the cavity can also be funnel-shaped, and the lowest point of the cavity can be connected to one end of the second abrasive recovery pipe. During the polishing process at the polishing station, the abrasive mainly enters the receiving funnel through the holes on the tooling and then enters the abrasive recovery funnel through the first abrasive recovery pipe to achieve backflow. Some of it will splash to other places, and this part will enter the abrasive recovery funnel through the grid plate, the cavity, and the second abrasive recovery pipe to achieve backflow.

[0035] In this embodiment, the abrasive supply system 8 includes an abrasive cylinder 81, a compression cylinder (not shown in the figure), and a compression piston 82. The compression piston is installed at the end of the push rod of the compression cylinder and is located inside the abrasive cylinder. The abrasive cylinder is connected to the switching valve. The switching valve is also connected to one end of the abrasive feed pipe 83, and the other end of the abrasive feed pipe is connected to the discharge channel of the pressing head. The working principle of the abrasive supply system is similar to that of an air pump, enabling the supply and return of abrasive.

[0036] In this embodiment, the polishing machine is further provided with a hydraulic device 9 and an air-cooling device 10. The hydraulic device is located on the side of the polishing machine, and the air-cooling device is located on the top of the polishing machine.

[0037] In this embodiment, the workstation also includes a spare workstation 25, which is located between the polishing workstation and the loading workstation. For example, a blowing device can be installed at the spare workstation for cleaning the tooling.

[0038] The turntable can be driven to rotate by a rotary drive mechanism, which is existing technology and will not be described in detail here.

[0039] The working principle and process of this utility model:

[0040] The turntable rotates counterclockwise continuously. The product is placed at the loading station. After the sensor detects that there is a product at the loading station, the product rotates to the polishing station. The mold closing device presses the product down. The mold closing device is equipped with an abrasive feed pipe. The abrasive supply system is started and abrasive is transported through the abrasive feed pipe to polish the product. After the abrasive enters the product, it falls into the receiving funnel and is collected in the abrasive recovery funnel through the first abrasive recovery pipe.

[0041] After polishing is completed, the mold closing device automatically lifts up, and the product is transferred to the unloading station. After the sensor detects that there is a product at the loading station, the unloading device moves the product to the collection area. The residual abrasive on the product will enter the mesh plate and flow into the receiving funnel, and be collected into the abrasive recovery funnel through the second abrasive recovery pipe.

[0042] The abrasive supply system switches between conveying and recovering abrasive through a switching valve. The principle is similar to that of an air pump, so it will not be described in detail.

[0043] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
