Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inner grinding rods, and more specifically to an inner grinding rod with a cleaning function. Background Art
[0002] Since the inner wall of the cast pipe is relatively rough during the production process, in order to improve its quality and make it better meet the needs of customers, it is often necessary to grind its inner wall. When grinding the inside of the steel pipe, a lot of dust and debris are usually generated. The existing grinding device is generally offline after the steel pipe is ground, and a separate workstation is used to blow the inside of the steel pipe. This cleaning method reduces the factory's production and processing efficiency for steel pipes, and increases the factory's production cost for material processing, which is relatively inconvenient.
[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and an inner grinding rod with a cleaning function is provided, in order to achieve a purpose with more practical value. Utility Model Content
[0004] In order to overcome the above defects of the prior art, the utility model provides an inner grinding rod with a cleaning function to solve the problems existing in the above background technology.
[0005] The utility model provides the following technical solutions: an inner grinding rod with a cleaning function, comprising an inner grinding rod main body, an outer rod penetrating the inner side of the inner grinding rod main body, air guide grooves penetrating the inner side of the outer rod, two end covers fixedly installed on the outer side of the outer rod, the end covers are respectively arranged at the two ends of the inner grinding rod main body, bearings are arranged between the inner grinding rod main body and the outer rod, the number of the bearings is three, a front joint is installed at one end of the outer rod, a plurality of air outlet holes corresponding to the air guide grooves of the outer rod are evenly opened on the side of the front joint, and a drill bit is connected to the front of the front joint.
[0006] Furthermore, the bearing is configured as a needle roller bearing, which has a compact structure so that it can better meet the smaller radial space requirement between the inner grinding rod body and the outer rod, and at the same time has the excellent characteristics of low friction resistance, high speed, high load and smooth operation.
[0007] Furthermore, retaining rings are installed on both sides of the bearing. The retaining rings installed on both sides of the bearing are used to limit the installation of the bearing on the outside of the outer rod, thereby preventing the bearing from being displaced on the outer rod during actual use of the device, thereby affecting its uniform support for the outer inner grinding rod body.
[0008] Furthermore, a silicone gasket is arranged between the mutually contacting surfaces of the outer sleeve rod and the front joint, and the silicone gasket is used to improve the sealing of the connection between the outer sleeve rod and the front joint, thereby preventing high-speed airflow from leaking from the gap between the outer sleeve rod and the front joint, thereby affecting the airflow blowing into the material honing hole.
[0009] Furthermore, the outer sleeve rod and the end cap are connected by metal welding. By metal welding between the outer sleeve rod and the end cap, the connection strength between the outer sleeve rod and the end cap is improved, thereby reducing the possibility of breakage of the connection between the outer sleeve rod and the cap during use.
[0010] Furthermore, the drill bit is configured as a ratchet self-locking drill chuck. By configuring the drill bit as a ratchet self-locking drill chuck, the material can be fixed by the device after drilling, thereby better blowing and cleaning the debris in the inner wall of the material.
[0011] Technical effects and advantages of the utility model:
[0012] 1. The utility model is provided with an outer sleeve rod, a front joint, a drill bit, a head cover, and an air outlet. When in use, high-pressure gas is injected into the device from the air inlet of the outer sleeve rod, and the gas is discharged through the air outlet. Thus, after the device drills a hole, the debris inside the material can be quickly cleaned, the material processing procedure is simplified, and the practicability of the device is greatly improved.
[0013] 2. The utility model sets the bearing as a needle roller bearing, which has a compact structure, so that it can better meet the smaller radial space requirement between the inner grinding rod body and the outer rod. At the same time, it has the excellent characteristics of small friction resistance, high speed, high load and smooth operation, which is very suitable for the high-speed use requirements of the device during grinding, and greatly improves the practicability of the device.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] Example 1: Please refer to Figure 1-4 The utility model provides an inner grinding rod with a cleaning function, comprising an inner grinding rod body 101, an outer rod 102 is provided on the inner side of the inner grinding rod body 101, and air guide grooves are provided at both ends of the outer rod 102. Two end covers 107 are fixedly installed on the outer side of the outer rod 102, and the end covers 107 are respectively provided at both ends of the inner grinding rod body 101. A bearing 105 is provided between the inner grinding rod body 101 and the outer rod 102, and the number of the bearings 105 is three. A front joint 103 is installed at one end of the outer rod 102, and a plurality of air outlet holes 109 corresponding to the air guide grooves of the outer rod 102 are evenly opened on the side of the front joint 103, and a drill bit 104 is connected to the front of the front joint 103.
[0021] Working principle: When in use, after the device has honed the material, the position between the device and the material is fixedly connected through the drill bit 104, and then a high-speed airflow is introduced from one end of the outer rod 102, input into the front joint 103 through the air guide groove of the outer rod 102, and then the gas is discharged through the air outlet 109 on the front joint 103, thereby blowing the dust in the gap between the inner grinding rod body 101 and the material, so that it is blown out of the material honing hole along with the air flow, thereby realizing rapid cleaning of the dust in the material honing hole, so as to improve the efficiency of the device in processing materials.
[0022] Embodiment 2:
[0023] The difference between the second embodiment and the first embodiment is that the bearing 105 is set as a needle bearing, and retaining rings 108 are installed on both sides of the bearing 105. A silicone gasket 106 is set between the mutually abutting surfaces of the outer rod 102 and the front joint 103. The outer rod 102 and the head cover 107 are connected by metal welding. The drill bit 104 is set as a ratchet self-locking drill chuck. When in use, by setting the bearing 105 as a needle bearing, the model of which is GB / T5801-1994, in order to meet the relatively small radial dimension space between the inner grinding rod body 101 and the outer rod 102, the position of the bearing 105 is fixed by the retaining ring 108, so as to To prevent the bearing 105 from being displaced on the device, the connection between the outer rod 102 and the front joint 103 is sealed by a silicone gasket 106 to prevent high-speed airflow from leaking from the gap between the front joint 103 and the outer rod 102, thereby affecting the purging effect of the dust in the device. The connection strength between the outer rod 102 and the head cover 107 is improved by welding. By setting the drill bit 104 as a ratchet self-locking drill chuck, the device can fix the material after drilling is completed, so that the incoming gas can better clean the debris on the inner wall of the material. At the same time, the device can meet the processing requirements of a maximum hole diameter of 58mm.
[0024] Finally: The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
