Description

Technical Field

[0001] The present invention relates to the technical field of concentric hole machining, and more particularly to a device for machining concentric holes of magnesium alloy parts. Background Art

[0002] Magnesium alloy is an alloy composed of magnesium as the base and other elements added. It has the following characteristics: high strength: magnesium alloy has relatively high strength and stiffness, can withstand large loads, and at the same time maintains excellent stability; large elastic modulus: magnesium alloy has a large elastic modulus, which means that it can recover to its original state better when subjected to external forces.

[0003] A magnesium alloy concentric hole machining device is a device specifically used for machining concentric holes. The magnesium alloy concentric hole machining device is mainly used to machine two or more holes with the same diameter and coincident axes on a workpiece. These holes play a key role in aspects such as mechanical assembly and the movement of rotating components, and can ensure the precise fit and smooth movement of components.

[0004] During the use of existing magnesium alloy concentric hole machining devices, there are some deficiencies as follows:

[0005] During the machining of specific magnesium alloy concentric holes, different machining methods are selected from the center hole, annular groove, and annular groove opened on the outside of the circular groove according to different actual machining requirements. When existing machining equipment is used for machining, different machining equipment needs to be selected according to the machining requirements. Therefore, existing machining equipment cannot be applied to multiple machining situations, and existing equipment needs to replace and adjust the cutting tool when performing different machining requirements. Existing equipment takes a lot of time to adjust during adjustment, so it is not convenient for users to adjust the equipment. Summary of the Invention

The cross-sectional dimension of the square sliding block has a clearance fit with the cross-sectional dimension of the first sliding groove.

[0016] The technical effects and advantages of the present invention:

[0017] 1. During the processing of the circular hole in the present invention, first, a suitable drill bit is selected according to the diameter of the circular hole, then the drill bit is placed on one side of the adjustment and positioning component, and then the electromagnetic positioning column works to make the electromagnetic sliding column energized, and then the electromagnetic sliding ring slides on the outside of the electromagnetic sliding column, thereby driving the push column to move. The push column is used to push the push component to move away from the power component, thereby driving the push ring body to slide on the outside of the rotating shaft, so that the distance between the push ring body and the positioning circular plate is shortened. Then the angle between the first U-shaped arm and the second circular hole becomes smaller, and at the same time, the rotating positioning plate rotates along the rotating hole and drives the first U-shaped arm to rotate. The second U-shaped arm rotates along the second circular hole, thereby driving the positioning block and the pulling shaft to rotate along the second circular hole. Then, the pulling shaft is used to push the clamping and grooving component, and under the positioning of the square sliding block in the first sliding groove, the clamping and grooving component moves towards the clamping column. Then, the cutting tool clamping block and the clamping protrusion clamp the opening drill bit. Then, the power component works to drive the rotating shaft clamping component and the rotating shaft to rotate, thereby driving the push component, the adjustment arm component, the annular groove opening component, the adjustment and positioning component, the clamping and grooving component, and the drill bit clamped by the clamping and grooving component to rotate. Then, the sliding power component is used to push the workpiece clamping component to clamp and position the magnesium alloy to move on the positioning track towards the concentric hole processing component to approach, and drilling work can effectively drill the magnesium alloy part, which is convenient for the user to quickly replace drill bits with different diameters.

[0018] 2. During the process of machining an annular groove, the drill bit clamped by the clamping and grooving assembly is removed. Then, the pushing column drives the pushing assembly to move, and the second U-shaped arm rotates along the second rotating positioning shaft. Subsequently, the distance between the clamping and grooving assembly and the center of the clamping column is adjusted by the positioning block and the pulling shaft, and then the distance between the second tool and the center of the clamping column is adjusted. Then, the power assembly operates to drive the rotating shaft clamping assembly and the rotating shaft to rotate, and then drives the pushing assembly, the adjusting arm assembly, the annular groove opening assembly, the adjusting and positioning assembly, the clamping and grooving assembly, and the clamping and grooving assembly to rotate. Then, the sliding power assembly pushes the magnesium alloy part clamped and positioned by the workpiece clamping assembly to move on the positioning track and approach the concentric hole machining assembly, so that an annular groove can be opened on the magnesium alloy part. Moreover, the clamping and grooving assembly can be sequentially expanded to open an annular groove with a specified width on the magnesium alloy part, enabling the device to machine an annular groove according to actual processing requirements.

[0019] 3. When the circular hole needs to be enlarged or an annular groove needs to be opened inside the circular hole, the rotating shaft is loosened by the rotating shaft clamping assembly, and then the clamping column is installed on the rotating shaft clamping assembly and positioned. When the rotating shaft is removed, the pushing assembly, the adjusting arm assembly, the annular groove opening assembly, the adjusting and positioning assembly, and the clamping and grooving assembly are synchronously removed. At this time, the pushing column is moved to the side close to the magnesium alloy part. Then, after the concentric hole machining assembly is positioned, according to the diameter of the circular hole, the pushing column pushes the pushing assembly to reduce the angle between the first U-shaped arm and the second U-shaped arm, and the distance between the rotating limit shaft and the clamping and grooving assembly is shortened. Subsequently, the rotating limit shaft drives the annular groove opening assembly to move, and the telescopic rod extends, so as to adjust the distance between the outside of the first tool and the center of the sliding adjustment ring, thus being able to adapt to the grooving work inside circular holes with different diameters and facilitating the use of the device.

[0020] 4. The present invention can be used in various machining situations of magnesium alloy parts, enabling different machining requirements to be achieved by a single device during the concentric hole machining of magnesium alloy parts, which is convenient for users. The limiting ring can effectively limit the pushing assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In a preferred embodiment, the annular groove opening assembly 204 includes a sliding adjustment ring 2041. On the outer side of the sliding adjustment ring 2041, a telescopic rod 2042 is fixedly connected. A third circular hole 2043 is formed on the outer side of the telescopic rod 2042. A first cutter 2044 is installed on the outer side of the third circular hole 2043; during the processing of the circular hole, first select a suitable drill bit according to the diameter of the circular hole, then place the drill bit on one side of the adjustment and positioning assembly 205, then make the electromagnetic sliding column 104 energized by the operation of the electromagnetic positioning column 103, and then make the electromagnetic sliding ring 105 slide on the outer side of the electromagnetic sliding column 104, thereby driving the push column 106 to move. The push column 106 pushes the push assembly 202 to move away from the power assembly 2011, thereby driving the push ring body 2021 to slide on the outer side of the rotating shaft 2013, so that the distance between the push ring body 2021 and the positioning circular plate 2051 is shortened, and then the angle between the first U-shaped arm 2031 and the second circular hole 2036 becomes smaller, and at the same time the rotary positioning plate 2032 rotates along the rotary hole 2033 and drives the first U-shaped arm 2031 to rotate, and the second U-shaped arm 2035 rotates along the second circular hole 2036, thereby driving the positioning block 2037 and the pulling shaft 2038 to rotate along the second circular hole 2036, and then the pulling shaft 2038 pushes the clamping and grooving assembly 206 and under the positioning of the square sliding block 2062 by the first sliding groove 2056, the clamping and grooving assembly 206 moves towards the clamping column 2057. Then, the opening drill bit is clamped by the tool clamping block 2063 and the clamping protrusion 2064. Then, the power assembly 2011 operates to drive the rotating shaft clamping assembly 2012 and the rotating shaft 2013 to rotate, thereby driving the push assembly 202, the adjusting arm assembly 203, the annular groove opening assembly 204, the adjustment and positioning assembly 205, the clamping and grooving assembly 206, and the drill bit clamped by the clamping and grooving assembly 206 to rotate. Then, the magnesium alloy clamped and positioned by the workpiece clamping assembly 108 is pushed by the sliding power assembly 102 to move on the positioning track 107 towards the concentric hole processing assembly 2 for drilling work, which can effectively drill the magnesium alloy parts and facilitate the user to quickly replace drill bits with different diameters.

[0037] In a preferred embodiment, the adjustment and positioning assembly 205 includes a positioning circular plate 2051. A second U-shaped groove 2052 is formed on the outer side of the positioning circular plate 2051. A second rotating positioning shaft 2053 is installed on the inner side of the second U-shaped groove 2052. A baffle 2054 is fixedly connected to the inner side of the second U-shaped groove 2052. A clamping column 2057 is fixedly connected to one side of the positioning circular plate 2051. A limiting strip 2055 is fixedly connected to one side of the positioning circular plate 2051. A first sliding groove 2056 is formed on the side of the limiting strip 2055 close to the second U-shaped groove 2052. During the process of machining an annular groove, the drill bit clamped by the clamping and grooving assembly 206 is removed. Then, the pushing assembly 202 is driven to move by the pushing column 106. Then, the second U-shaped arm 2035 rotates along the second rotating positioning shaft 2053. Subsequently, the distance between the clamping and grooving assembly 206 and the center of the clamping column 2057 is adjusted by the rotation of the positioning block 2037 and the pulling shaft 2038. Consequently, the distance between the second cutter 2067 and the center of the clamping column 2057 is adjusted. Then, the power assembly 2011 operates to drive the rotating shaft clamping assembly 2012 and the rotating shaft 2013 to rotate, thereby driving the pushing assembly 202, the adjusting arm assembly 203, the annular groove opening assembly 204, the adjustment and positioning assembly 205, the clamping and grooving assembly 206, and the clamping and grooving assembly 206 to rotate. Then, the magnesium alloy part clamped and positioned by the workpiece clamping assembly 108 is pushed by the sliding power assembly 102 to move on the positioning track 107 towards the concentric hole machining assembly 2, so that an annular groove can be opened on the magnesium alloy part. Moreover, the clamping and grooving assembly 206 can be sequentially expanded to open an annular groove with a specified width on the magnesium alloy part, enabling the device to machine an annular groove according to actual processing requirements.

[0038] In a preferred embodiment, the clamping and grooving assembly 206 includes an L-shaped fixing plate 2061. Square sliding blocks 2062 are fixedly connected to both the front and back surfaces of the L-shaped fixing plate 2061. A tool clamping block 2063 is fixedly connected to the bottom of the L-shaped fixing plate 2061. A clamping protrusion 2064 is fixedly connected to the inner side of the tool clamping block 2063. A limiting groove 2065 is formed on the outer side of the L-shaped fixing plate 2061. Second sliding grooves 2066 are formed on both the front and back surfaces inside the limiting groove 2065. A second tool 2067 is fixedly connected to one side of the L-shaped fixing plate 2061. When it is necessary to enlarge a circular hole or to form an annular groove inside the circular hole, the rotating shaft clamping assembly 2012 releases the rotating shaft 2013, and then the clamping column 2057 is installed on the rotating shaft clamping assembly 2012 and positioned. When the rotating shaft 2013 is removed, the pushing assembly 202, the adjusting arm assembly 203, the annular groove forming assembly 204, the adjusting and positioning assembly 205, and the clamping and grooving assembly 206 are synchronously removed. At this time, the pushing column 106 is moved to the side close to the magnesium alloy part. Then, after the concentric hole machining assembly 2 is positioned, according to the diameter of the circular hole, the pushing column 106 pushes the pushing assembly 202 to reduce the angle between the first U-shaped arm 2031 and the second U-shaped arm 2035, and to shorten the distance between the rotation limiting shaft 2034 and the clamping and grooving assembly 206. Subsequently, the rotation limiting shaft 2034 drives the annular groove forming assembly 204 to move, and the telescopic rod 2042 extends, so as to adjust the distance between the outside of the first tool 2044 and the center of the sliding adjustment ring 2041, thereby enabling the grooving operation inside circular holes with different diameters and facilitating the use of the equipment.

[0039] In a preferred embodiment, there is an interference fit between the diameter of the first circular hole 2022 and the diameter of the rotating shaft 2013, an interference fit between the diameter of the first rotation positioning shaft 2024 and the diameter of the rotation hole 2033. A fillet is formed on the outer side of the rotation positioning plate 2032, and the center of the fillet of the rotation positioning plate 2032 coincides with the center of the rotation hole 2033. There is an interference fit between the diameter of the pulling shaft 2038 and the height of the second sliding groove 2066, and an interference fit between the length of the pulling shaft 2038 and the distance between the front and back surfaces inside the second sliding groove 2066.

[0040] In a preferred embodiment, there is a clearance fit between the diameter of the third circular hole 2043 and the inner diameter of the rotation limit shaft 2034, a clearance fit between the diameter of the second circular hole 2036 and the diameter of the second rotation positioning shaft 2053, a clearance fit between the inner diameter of the sliding adjustment ring 2041 and the diameter of the rotation shaft 2013. The distance between the push columns 106 is larger than the outer diameter of the limit ring 2014 and smaller than the outer diameter of the push ring body 2021. The diameter of the push column 106 is smaller than the difference between the diameter of the push ring body 2021 and the diameter of the limit ring 2014, and the diameter of the push column 106 is as large as possible without affecting the use of the limit ring 2014. The cross-sectional dimension of the square sliding block 2062 has a clearance fit with the cross-sectional dimension of the first sliding groove 2056.

[0041] The working principle of the present invention: During the processing of the circular hole, first select a suitable drill bit according to the diameter of the circular hole, then place the drill bit on one side of the adjustment and positioning assembly 205, and then make the electromagnetic sliding column 104 energized by the operation of the electromagnetic positioning column 103. Then, make the electromagnetic sliding ring 105 slide on the outside of the electromagnetic sliding column 104, and then drive the push column 106 to move. The push column 106 pushes the push assembly 202 to move away from the power assembly 2011, and then drives the push ring body 2021 to slide on the outside of the rotation shaft 2013. Then, the distance between the push ring body 2021 and the positioning circular plate 2051 is shortened. Then, the angle between the first U-shaped arm 2031 and the second circular hole 2036 becomes smaller, and at the same time, the rotation positioning plate 2032 rotates along the rotation hole 2033 and drives the first U-shaped arm 2031 to rotate. The second U-shaped arm 2035 rotates along the second circular hole 2036, and then drives the positioning block 2037 and the pulling shaft 2038 to rotate along the second circular hole 2036. Then, the pulling shaft 2038 pushes the clamping and grooving assembly 206, and under the positioning of the square sliding block 2062 by the first sliding groove 2056, the clamping and grooving assembly 206 moves towards the clamping column 2057. Then, the cutting tool clamping block 2063 and the clamping protrusion 2064 clamp the hole-opening drill bit. Then, the power assembly 2011 operates to drive the rotation shaft clamping assembly 2012 and the rotation shaft 2013 to rotate, and then drives the push assembly 202, the adjustment arm assembly 203, the annular groove opening assembly 204, the adjustment and positioning assembly 205, the clamping and grooving assembly 206, and the drill bit clamped by the clamping and grooving assembly 206 to rotate. Then, the sliding power assembly 102 pushes the magnesium alloy clamped and positioned by the workpiece clamping assembly 108 to move on the positioning track 107 towards the concentric hole processing assembly 2 for drilling work, which can effectively drill the magnesium alloy part and facilitate the user to quickly replace drill bits with different diameters.

[0042] During the process of machining an annular groove, remove the drill bit clamped by the clamping and grooving assembly 206. Then, drive the pushing assembly 202 to move by the pushing column 106. Next, make the second U-shaped arm 2035 rotate along the second rotation positioning shaft 2053. Subsequently, rotate and adjust the distance between the clamping and grooving assembly 206 and the center of the clamping column 2057 through the positioning block 2037 and the pulling shaft 2038. Consequently, the distance between the second cutter 2067 and the center of the clamping column 2057 is adjusted. Then, drive the rotating shaft clamping assembly 2012 and the rotating shaft 2013 to rotate by the operation of the power assembly 2011. Subsequently, drive the pushing assembly 202, the adjusting arm assembly 203, the annular groove opening assembly 204, the adjusting and positioning assembly 205, the clamping and grooving assembly 206, and the clamping and grooving assembly 206 to rotate. Then, push the magnesium alloy part clamped and positioned by the workpiece clamping assembly 108 to move on the positioning track 107 towards the concentric hole machining assembly 2 by the sliding power assembly 102, so as to machine an annular groove on the magnesium alloy part. Moreover, the clamping and grooving assembly 206 can be successively enlarged to machine an annular groove with a specified width on the magnesium alloy part, enabling the device to machine an annular groove according to actual processing requirements;

[0043] When it is necessary to enlarge a circular hole or machine an annular groove inside the circular hole, loosen the rotating shaft 2013 by the rotating shaft clamping assembly 2012. Then, install the clamping column 2057 on the rotating shaft clamping assembly 2012 and position it. When removing the rotating shaft 2013, the pushing assembly 202, the adjusting arm assembly 203, the annular groove opening assembly 204, the adjusting and positioning assembly 205, and the clamping and grooving assembly 206 are synchronously removed. At this time, move the pushing column 106 to the side close to the magnesium alloy part.
