Description

Technical Field

[0001] The utility model relates to the field of mechanical processing equipment, in particular to a grinding device for mechanical processing. Background Art

[0002] Some mechanical parts need to go through a grinding process after forming. During the grinding process, metal debris will be generated, which makes it difficult to clean up later and affects the surrounding working environment. In order to solve the above technical problems, patent CN219380189U discloses a grinder that achieves the effect of debris suction and treatment by arranging a dust collection ring cover, a dust removal box and an exhaust fan above the grinding disc, but it still has the following defects:

[0003] 1. When the grinding device grinds mechanical parts, the debris generated is affected by the cutting force and moves in all directions. The adsorption force of the dust collection ring cover is exactly opposite to the direction of the debris divergence movement. In order to ensure that the debris can be smoothly sucked into the dust collection ring cover, the adsorption wind force provided by the device must overcome the resistance of the debris divergence movement, resulting in high requirements for the adsorption wind force of the device.

[0004] 2. Since the device requires high wind force for adsorption, when air carrying debris passes through the filter, the strong wind force may cause the debris to pass through the gaps in the filter or get stuck in the gaps in the filter. Therefore, this patent has the risk of poor exhaust or debris still being carried in the exhausted air.

[0005] 3. When the debris generated during the grinding process of mechanical parts is large or heavy, the kinetic energy of the debris to disperse in all directions is high. Such debris will still fall around the work area and cannot be sucked in by the dust collection ring hood.

[0006] In view of this, how to provide a grinding device that can partially or completely solve the above-mentioned technical problems is a technical problem that people in this field urgently need to solve. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] Reference Figure 1-Figure 3 The utility model provides a grinding device for mechanical processing, in which a fixed tool 1 can fix a workpiece for grinding, and comprises: a first bellows 2, the first bellows 2 is hollow inside, and a plurality of air holes 201 are arranged through its upper surface; an operating platform 3, the operating platform 3 is fixedly arranged on the upper surface of the first bellows 2, and the fixed tool 1 is installed on the upper surface of the operating platform 3; a second bellows 4, the second bellows 4 is connected with the first bellows 2 and a vertically arranged exhaust duct 5, a filter screen 6 is arranged in the exhaust duct 5, and an exhaust fan 7 is arranged near the exhaust port of the exhaust duct 5; a collecting tank 8, the collecting tank 8 is arranged below the second bellows 4 and is connected with the second bellows 4; a grinding mechanism, the grinding mechanism is located above the operating platform 3 and can grind the workpiece.

[0041] like Figure 2 As shown, the grinding mechanism includes: a cylinder 9, which is located above the operating platform 3 and the telescopic end of the cylinder 9 extends downward; a rotating motor 10, which is fixedly connected to the telescopic end of the cylinder 9; a grinding disc 11, which is fixedly connected to the output end of the rotating motor 10; a support frame 12, one end of the support frame 12 is fixed to the ground, and the other end extends above the cylinder 9, and the cylinder 9 is fixedly connected to the support frame 12.

[0042] like Figure 1As shown, in this embodiment, it also includes: an isolation cover 13, the isolation cover 13 is fixedly connected to the telescopic end of the cylinder 9, and the connection is located above the rotating motor 10. The isolation cover 13 can cover the upper surface of the first bellows 2. The isolation cover 13 can be made of heat-resistant transparent glass, which is convenient for the operator to grasp the grinding situation in real time.

[0043] In this embodiment, the air flow cross section of the exhaust duct 5 is larger than the air flow cross section of the second wind box 4. It also includes a connecting pipe 14 and a support block 15. One end of the connecting pipe 14 is connected to the first wind box 2, and the other end is connected to the second wind box 4. The bottom surface of the second wind box 4 is higher than the bottom surface of the first wind box 2. The collecting tank 8 is inclined along the flow direction of the air, and the position is lower near the end of the exhaust duct 5. A special-shaped gap is formed between the collecting tank 8 and the connecting pipe 14 and the ground, and the support block 15 is adapted to the shape of the special-shaped gap and fixed in the special-shaped gap. A discharge port is provided at one end of the collecting tank 8 near the exhaust duct 5, and a door body 16 is installed on the discharge port.

[0044] In this embodiment, Figure 1 The front and rear sides of the first bellows 2 are also provided with manipulators capable of grabbing the polished workpiece, so as to realize the loading and unloading of the polished workpiece.

[0045] The specific working process is as follows:

[0046] The manipulator loads the workpiece to be polished into the fixed fixture 1, and starts the cylinder 9, which drives the polishing disc 11 to move down and contact the workpiece. At the same time, the isolation cover 13 moves down and covers the first bellows 2. Figure 1 shown.

[0047] Start the rotating motor 10 to start the grinding process of the grinding workpiece, and start the exhaust fan 7 at the same time. The exhaust fan 7 can discharge the air in the first bellows 2 and the second bellows 4, so that the first bellows 2 creates a negative pressure environment and sucks air from the air hole 201. The debris generated during the grinding process enters the first bellows 2 together with the air, and the air entrained with the debris passes through the connecting pipe 14 and the second bellows 4 in turn. Some heavier debris falls to the collection tank 8 below during the movement and rolls to the right side of the collection tank 8 due to the inclined setting of the collection tank 8. The remaining debris enters the exhaust duct 5 along with the air.

[0048] When the air containing debris enters the exhaust duct 5, the area of ​​the flow cross section suddenly increases, causing the flow rate to decrease. Part of the debris falls directly into the collection trough 8 below, and the remaining debris is filtered by the filter net 6 and also falls into the collection trough 8 below.

[0049] The operator can clearly observe the grinding of the workpiece through the isolation cover 13. After the grinding is finished, the workpiece is unloaded by another manipulator. After a certain number of workpieces are polished, the door body 16 is opened to collect the debris stored in the collecting tank 8 and take it out for processing.

[0050] The utility model provides a grinding device for mechanical processing, in which the air hole 201 generates downward adsorption wind force under the action of the exhaust fan 7, and the debris generated by the grinding of the workpiece is automatically dispersed around the operating platform 3 under the action of the grinding cutting force, and enters the first wind box 2 under the influence of the downward adsorption wind force. The adsorption wind force does not need to overcome the divergence power of the debris, and can adsorb the debris with the help of the gravity of the debris itself, which greatly reduces the adsorption wind force requirement of the debris. The debris sucked into the first wind box 2 moves along the second wind box 4 and passes through the filter 6 in the exhaust duct 5 to be separated from the air and fall into the collection tank 8. The exhaust duct 5 is arranged vertically, and when the air entrained with the debris passes through the exhaust duct 5, the air is forcibly turned, so the wind force will be reduced. In this case, when the air entrained with the debris passes through the filter 6, the separation effect of the debris and the air is greatly improved. An isolation cover 13 is provided above the first bellows 2. The isolation cover 13 and the grinding disc 11 can move up and down synchronously. When the grinding disc 11 is working, the isolation cover 13 can cover the first bellows 2. In this way, all debris is confined within the isolation cover 13 and can be completely sucked into the first bellows 2, thereby improving the collection rate of debris. The air flow cross-section of the exhaust duct 5 is larger than the air flow cross-section of the second bellows 4. According to the "narrow tube effect", the flow velocity of the air will decrease when passing through the exhaust duct 5, which can further improve the separation effect of debris and air. The collection trough 8 is tilted below the second bellows 4, and some of the debris dropped by the air entrained with debris during the movement of the second bellows 4 will also fall into the collection trough 8; the debris in the collection trough 8 can slide to the lower end of the collection trough 8 by its own gravity and be taken out and processed from the door body 16. The connecting pipe 14 can make the bottom surface of the second wind box 4 higher than the bottom surface of the first wind box 2 and provide installation space for the collecting tank 8. The support block 15 can support the collecting tank 8 and the connecting pipe 14 to improve the overall stability of the device.
