Its purpose is to solve the problem that the existing grinding device cannot simultaneously meet the cooling and dust collection functions of the grinding device;

[0004] By referring to the above comparative documents, it can be seen that the prior art still has the following deficiencies. Although the grinding device integrates water sprinkling cooling and dust collection, when the grinding device is hand-held to grind the corresponding accessories of the regulating valve, since there is more water inside the grinding device, the grinding device is heavy, so it is very laborious to work with the hand-held grinding device. If less water is filled in order to reduce gravity, it is often necessary to repeatedly add water to the inside of the device, resulting in inconvenient operation. In addition, a dust collection structure is added to absorb dust, but the dust collection structure is also installed on the grinding device, which will increase the burden of the grinding device when working by hand, resulting in insufficient ease and effort in the operation. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-7 The utility model provides a technical solution: a regulating valve grinding device, comprising a storage box 1 and a grinding gun 2, a storage chamber 21 is opened on the left side of the upper end of the storage box 1, a concave support ring 6 is fixed to the upper end of the storage chamber 21, and a supporting circular plate 7 close to the gun handle is fixedly sleeved on the periphery of the grinding gun 2, the outer edge of the supporting circular plate 7 is arc-shaped, and spring return rods 17 fixed to the inner wall of the storage chamber 21 are provided on both sides of the upper end of the concave support ring 6, and the end of the spring return rod 17 is connected to a frustum block 18, and the inclined surface of the frustum block 18 corresponds to the arc surface of the supporting circular plate 7.

[0028] When the various accessories of the regulating valve are ground and processed by the grinding device, the grinding gun 2 is taken out from the storage chamber 21, and the truncated cone block 18 is pressed on the supporting circular plate 7. During this process, the supporting circular plate 7 will push the truncated cone block 18 outward along the inclined surface of the truncated cone block 18, and the truncated cone block 18 will compress the spring return rod 17, so that the supporting circular plate 7 and the grinding gun 2 can be easily taken out from the storage chamber 21.

[0029] In this embodiment, the grinding gun 2 is inserted into the storage chamber 21, and a motor 3 is installed inside the grinding gun 2. The power end of the motor 3 is connected to a rotating shaft 4. The rotating shaft 4 rotates and passes through the gun head of the grinding gun 2. A grinding disc 5 is fixed to the end of the rotating shaft 4. A water storage chamber 9 is opened at the right end of the storage box 1, and a receiving groove 8 is opened at the upper end of the storage box 1. A water pump 11 connected to the water storage chamber 9 is fixed in the receiving groove 8, and the water outlet of the water pump 11 is connected to a spring water pipe 12. A water pipe 13 is provided in the gun 2, and the end of the spring water pipe 12 is connected to one end of the water pipe 13. An annular pipe 15 close to the grinding disc 5 is fixedly sleeved on the periphery of the grinding gun 2, and a plurality of cooling nozzles 16 are connected to the lower end of the annular pipe 15. A solenoid valve 14 is connected between the annular pipe 15 and the water pipe 13. A first switch 19 and a second switch 20 are installed on the handle of the grinding gun 2. The first switch 19 is connected in series with the motor 3, and the second switch 20 is connected in series with the solenoid valve 14.

[0030] When the grinding gun 2 is taken out, the spring water pipe 12 will be stretched, and the motor 3 will be started through the first switch 19. The motor 3 drives the rotating shaft 4 and the grinding disc 5 to rotate. When the grinding disc 5 grinds the regulating valve, the water pump 11 is started. At the same time, the solenoid valve 14 is started through the second switch 20. The water pump 11 pumps the water in the water storage chamber 9 into the spring water pipe 12, the water pipe 13, the solenoid valve 14, the annular pipe 15 and the cooling nozzle 16. The water is sprayed from the cooling nozzle 16 and sprayed onto the grinding disc 5, which is beneficial to comprehensively cool the grinding disc 5 and ensure the service life of the grinding disc 5. In addition, a plurality of cooling nozzles 16 are provided, so the sprayed water will comprehensively reduce the dust generated by grinding to avoid dust during the grinding process.

[0031] In this embodiment, a water storage chamber 9 is opened at the right end of the storage box 1, and the lower end of the annular tube 15 is connected to a plurality of cooling nozzles 16.

[0032] Since the water is stored in the water storage chamber 9 in the storage box 1, and the grinding gun 2 and the storage box 1 can be used separately, when the grinding gun 2 is used alone to grind various accessories of the regulating valve, compared with the related existing technology, water does not need to be stored in the grinding gun 2, and there is no need to add an additional dust suction structure on the grinding gun 2. The weight of the grinding gun 2 is relatively light, which helps to reduce the burden of the handheld grinding gun 2 when grinding the regulating valve, making the weight of the grinding gun 2 relatively light, so the grinding operation is easy and labor-saving.

[0033] The upper end of the storage box 1 is connected to a water inlet valve 10 which is in communication with the water storage chamber 9 .

[0034] By opening the water inlet valve 10 , water can be added to the water storage chamber 9 , thereby ensuring the water storage capacity in the water storage chamber 9 .

[0035] In this embodiment, a concave support ring 6 is fixed to the upper end of the storage chamber 21, and a support circular plate 7 close to the gun handle is fixedly sleeved on the periphery of the grinding gun 2. The outer edge of the support circular plate 7 is arc-shaped, and both sides of the upper end of the concave support ring 6 are provided with spring return rods 17 fixed to the inner wall of the storage chamber 21. The end of the spring return rod 17 is connected to a frustum block 18, and the inclined surface of the frustum block 18 corresponds to the arc surface of the support circular plate 7.

[0036] When the grinding gun 2 is used and needs to be stored, the gun head of the grinding gun 2 is inserted downward into the storage chamber 21, and the spring water pipe 12 is automatically stored in the storage groove 8 after shrinking, so as to prevent the spring water pipe 12 from being exposed to the outside for a long time. In addition, when the gun head of the grinding gun 2 is inserted downward into the storage chamber 21, the arc surface of the outer edge of the supporting circular plate 7 will push the circular cone block 18 outward along the inclined surface of the circular cone block 18, and the circular cone block 18 will compress the spring return rod 17 until the concave support ring 6 supports the supporting circular plate 7. At this time, the circular cone block 18 is pressed on the supporting circular plate 7, achieving the effect of locking the supporting circular plate 7 to prevent the grinding gun 2 from falling out of the storage chamber 21. Therefore, inserting the grinding gun 2 into the storage chamber 21 can not only protect the grinding gun, but also make it convenient to carry the grinding device as a whole.

[0037] A handle 21 is fixed to the middle of the upper end of the storage box 1 .

[0038] The grinding device can be lifted by holding the handle 22, so as to facilitate carrying the grinding device.

[0039] Working principle:

[0040] When the various accessories of the regulating valve are ground by the grinding device, the grinding gun 2 is taken out from the storage chamber 21, the spring water pipe 12 will be stretched, and the motor 3 is started by the first switch 19. The motor 3 drives the rotating shaft 4 and the grinding disc 5 to rotate. When the grinding disc 5 grinds the regulating valve, under the premise of starting the water pump 11, the solenoid valve 14 is started by the second switch 20 at the same time. The water pump 11 pumps the water in the water storage chamber 9 into the spring water pipe 12, the water pipe 13, the solenoid valve 14, the annular pipe 15 and the cooling nozzle 16. The water is sprayed from the cooling nozzle 16 and sprayed onto the grinding disc 5, thereby facilitating the comprehensive cooling of the grinding disc 5. In addition, the sprayed water can comprehensively reduce the dust generated by grinding.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
