In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] In the existing technology, the center adjustment device does not have rotational freedom on the Z-axis perpendicular to the horizontal plane, which makes the horizontal angle of the center unadjustable. It is difficult to ensure that the center and the workpiece reach a concentric holding state, and it cannot meet the requirements under certain conditions.

[0032] Please see Figure 1 , Figure 1 This is a three-dimensional structural schematic diagram of a center adjustment device 100 according to one embodiment of the present invention. The present invention provides a center adjustment device 100, which includes a base 10, a center 20, an adjustment mechanism 30, and a horizontal angle adjustment member 40. The center 20 is used to abut against the workpiece. The adjustment mechanism 30 is rotatably connected to the base 10 about a first axis perpendicular to the horizontal plane. The center 20 is disposed on the adjustment mechanism 30. The horizontal angle adjustment member 40 is relatively movably disposed on the base 10 and connected to the adjustment mechanism 30. The horizontal angle adjustment member 40 can drive the adjustment mechanism 30 to rotate about the first axis, and keep the adjustment mechanism 30 and the base 10 relatively fixed.

[0033] Please refer to the following for details. Figure 3 , Figure 3 It is the top-level adjustment device in Figure 2The image shows a cross-sectional view along the BB direction. The tip 20 is connected to the adjusting mechanism 30 by clamping. It should be understood that the tip 20 can also be connected to the adjusting mechanism 30 by welding, gluing, or magnetic attraction. A first pin 913 is provided between the adjusting mechanism 30 and the base 10. The adjusting mechanism 30 has a first pin hole 911, and the base 10 has a second pin hole 912. The two ends of the first pin 913 engage with the first pin hole 911 and the second pin hole 912, respectively. The first axis is the axis of the first pin 913. It is understood that the first pin 913 enables the adjusting mechanism 30 and the base 10 to rotate around the first axis. It should be understood that in some other embodiments, bearings can be provided in the first pin hole 911 and the second pin hole 912, and the first pin 913 passes through the bearings to reduce the friction generated when the adjusting mechanism 30 rotates. Alternatively, in other embodiments, hinges, connecting rods or other structures can be used to achieve the rotational connection between the adjustment mechanism 30 and the base 10. This utility model does not specifically limit the rotational connection method between the adjustment mechanism 30 and the base 10.

[0034] It is understood that the horizontal angle adjusting member 40 has a driving function and can fix the adjusting mechanism 30 relative to the base 10. For example, in this embodiment, the horizontal angle adjusting member 40 is constructed as a screw, which can drive the adjusting mechanism 30 to rotate around the first axis, and can also abut against the adjusting mechanism 30 to achieve relative fixation of the position. In other embodiments, the horizontal angle adjusting member 40 can also be constructed as a bolt, pin, or other structure.

[0035] By setting up a horizontal angle adjusting member 40 and an adjusting mechanism 30, on the one hand, the tip 20 is set on the adjusting mechanism 30, and the adjusting mechanism 30 can rotate around a first axis perpendicular to the horizontal plane on the base 10, thereby changing the horizontal angle of the tip 20; on the other hand, the horizontal angle adjusting member 40 can be relatively movably connected to the base 10, and the horizontal angle adjusting member 40 can drive the adjusting mechanism 30 to rotate around the first axis. Furthermore, the horizontal angle adjusting member 40 can fix the adjusting mechanism 30 and the base 10 relatively, thereby cooperating with the adjusting mechanism 30 to adjust the horizontal angle of the tip 20, so as to help the tip and the workpiece to support each other concentrically and improve the machining accuracy of the workpiece.

[0036] In one embodiment of this implementation, please refer to Figure 1The horizontal angle adjusting component 40 includes two first screws 41, and the base 10 has two first threaded holes 42. The two first screws 41 are threaded into the two first threaded holes 42 respectively. The two first screws 41 abut against the opposite sides of the adjusting mechanism 30, thereby driving the adjusting mechanism 30 to rotate around the first axis and fixing the adjusting mechanism 30 and the base 10 relatively. It can be understood that when the two first screws 41 abut against the opposite sides of the adjusting mechanism 30, they can clamp the adjusting protrusion 921, thereby fixing the adjusting mechanism 30 and the base 10 relatively. Furthermore, when the two first screws 41 rotate in the first threaded holes 42, they can move relative to the base 10, thereby pushing the adjusting mechanism 30, which in turn drives the tip 20 to rotate around the first axis, thereby adjusting the horizontal angle of the tip 20.

[0037] Specifically, in combination Figure 1 The base 10 is provided with two spaced first fixing blocks 922, and two first threaded holes 42 are opened on the two first fixing blocks 922. The two first threaded holes 42 pass through the two first fixing blocks 922 respectively. The center lines of the two first threaded holes 42 coincide and are parallel to the horizontal plane. The center lines of the two first threaded holes 42 do not intersect with the first axis. Two first screws 41 are threadedly engaged with the two first threaded holes 42 respectively. The adjusting mechanism 30 is provided with an adjusting protrusion 921. The adjusting protrusion 921 is located between the two first fixing blocks 922, and the center lines of the two first threaded holes 42 pass through the adjusting protrusion 921. The two first screws 41 abut against the opposite sides of the adjusting protrusion 921 respectively.

[0038] In one embodiment of this implementation, combined with Figure 2 and Figure 3 , Figure 2 yes Figure 1 The image shows a front view of the tip adjustment device. The adjustment mechanism 30 includes a mounting block 31 and a connecting assembly 32. The connecting assembly 32 is rotatably connected to the base 10, and the mounting block 31 is connected to the tip 20. The mounting block 31 is rotatably connected to the connecting assembly 32 about a second axis, which is parallel to the horizontal plane. It is understood that when the mounting block 31 rotates about the second axis, it can drive the tip 20 to rotate about the second axis, thereby adjusting the pitch angle of the tip 20.

[0039] Specifically, in combination Figure 2 and Figure 3 , Figure 2 yes Figure 1 A front view of the top adjustment device 100; Figure 3 It is the top adjustment device 100 in Figure 2The image shows a sectional view along the BB direction. Mounting block 31 clamps the tip 20 in a clamping manner. Mounting block 31 has a third pin hole 961. Connecting component 32 has a second pin 962, the axis of which is the second axis. The second pin 962 and the third pin hole 961 are in clearance fit. A first pin hole 911 is formed on connecting component 32.

[0040] In one embodiment of this implementation, please refer to Figures 1 to 3 The top adjustment device 100 also includes a pitch adjustment member 50, which is relatively movably connected to the connecting assembly 32 and to the mounting block 31. The pitch adjustment member 50 can drive the mounting block 31 to rotate around the second axis and can fix the mounting block 31 and the connecting assembly 32 relatively.

[0041] Specifically, in combination Figures 1 to 3 The connecting component 32 has two second fixing blocks 931 spaced apart. Each second fixing block 931 has a third threaded hole 932 that passes through it. The center lines of the two third threaded holes 932 are parallel and perpendicular to the second axis, and do not intersect the second axis. The mounting block 31 is located between the two second fixing blocks 931, and the center lines of both third threaded holes 932 pass through the mounting block 31. The pitch adjustment component 50 includes two third screws 933, which are respectively inserted into the two third threaded holes 932 and abut against opposite sides of the mounting block 31. Understandably, when the two third screws 933 abut against the two sides of the mounting block 31, they can clamp the mounting block 31, thereby fixing the mounting block 31 and the connecting assembly 32 relatively. Furthermore, when the two third screws 933 rotate within the third threaded hole 932, they can move relative to the connecting assembly 32, thereby pushing the mounting block 31 to rotate around the second axis, which in turn allows the mounting block 31 to drive the tip 20 to rotate around the second axis, thus achieving adjustment of the tip 20's pitch angle.

[0042] In one embodiment of this implementation, please refer to Figure 1 and Figure 3 The connecting assembly 32 includes a first connector 321 and a second connector 322. The first connector 321 is slidably connected to the second connector 322 along a first direction inclined to a horizontal plane. The mounting block 31 is rotatably connected to the first connector 321 about a second axis, and the second connector 322 is rotatably connected to the base 10 about the first axis. It is understood that when the first connector 321 moves along the first direction inclined to a horizontal plane, its position in the direction perpendicular to the horizontal plane will change, thereby facilitating the height adjustment of the tip 20.

[0043] Specifically, in combination Figure 1 and Figure 3 The first direction is perpendicular to the second axis. A dovetail groove 941 extending along the first direction is provided on the second connector 322. A protrusion (not shown) adapted to the shape of the dovetail groove 941 is provided on the first connector 321. The protrusion and the dovetail groove 941 can slide together along the first direction. The bottom surface of the protrusion fits against the bottom wall of the dovetail groove 941, and both are inclined to the horizontal plane. A first pin hole 911 is formed on the second connector 322. A second pin 962 is connected to the first connector 321.

[0044] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 The top adjustment device 100 also includes a height adjustment member 60, which is slidably connected to the base 10 and connected to the first connector 321. The height adjustment member 60 can drive the first connector 321 to move along a first direction and fix the first connector 321 and the second connector 322 relative to each other.

[0045] Specifically, in combination Figure 2 and Figure 3 The height adjustment component 60 is constructed as a screw. It can be understood that the screw can push the first connecting member 321 to slide in the first direction, and can also abut against the first connecting member 321 to achieve relative fixation of the position.

[0046] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 The height adjustment component 60 includes two second screws 61, and the base 10 includes two second threaded holes 62. The two second screws 61 are threaded into the two second threaded holes 62 respectively. The two second screws 61 can abut against both sides of the first connecting member 321, thereby driving the first connecting member 321 to move along a first direction and fixing the first connecting member 321 and the base 10 relatively. It should be noted that when the two second screws 61 abut against the first connecting member 321, they can work together with the second connecting member 322 to clamp and fix the first connecting member 321, thereby fixing the first connecting member 321 and the second connecting member 322 relatively. Furthermore, when the two second screws 61 rotate within the second threaded holes 62, they can move relative to the base 10, thereby pushing the first connecting member 321 to move along the first direction, thus changing the position of the first connecting member 321 in the direction perpendicular to the horizontal plane, thereby achieving height adjustment of the tip 20. Understandably, choosing to use two second screws 61 as the height adjustment component 60 is beneficial in two ways: firstly, it simplifies the structure of the top adjustment device 100, and secondly, it reduces the manufacturing cost of the top adjustment device 100.

[0047] Specifically, in combination Figure 2 and Figure 3The base 10 is provided with two third fixing blocks 934, and the third fixing blocks 934 are provided with second threaded holes 62. The second threaded holes 62 penetrate the third fixing blocks 934. The center line of one second threaded hole 62 is perpendicular to the horizontal plane, and the center line of the other second threaded hole 62 is parallel to the horizontal plane. The first direction is perpendicular to the second axis. The height adjustment component 60 includes two second screws 61, which are respectively inserted into the two second threaded holes 62. One second screw 61 abuts against the top side of the first connector 321 and can provide a downward force in the vertical direction. The other second screw 61 abuts against the side of the first connector opposite to the second connector 322 and can provide a leftward force in the horizontal direction.

[0048] In one embodiment of this implementation, please refer to Figure 1 , Figure 3 and Figure 4 , Figure 4 It is the top-level adjustment device in Figure 3 The image shows a cross-sectional view along the CC direction. The center adjustment device 100 also includes a base 70 and a drive driver 80. The drive driver 80 is mounted on the base 70, and a base 10 is slidably connected to the base 70. The base 10 is positioned on the drive end of the drive driver 80, and the drive direction of the drive driver 80 is a second direction, parallel to the horizontal plane. It is understood that the drive driver 80 can drive the base 10 to move along the second direction, thereby allowing the center 20 to move closer to or further away from the workpiece to be processed, which is beneficial for improving the degree of automation.

[0049] Specifically, in combination Figure 1 , Figure 3 and Figure 4 The actuator 80 is a cylinder, which is connected to the base 70. The base 10 is connected to the drive end of the cylinder. A first guide rail assembly 951 is provided on the base 70. The first guide rail assembly 951 extends along the second direction. The base 10 is connected to the first guide rail assembly 951. The first guide rail assembly 951 can provide guidance for the movement of the base 10 relative to the base 70 along the second direction.

[0050] In one embodiment of this implementation, please refer to Figure 3The base 10 includes an elastic element 13, a third connecting element 11, and a fourth connecting element 12. The third connecting element 11 and the fourth connecting element 12 are connected by the elastic element 13, which can elastically deform along a second direction. The fourth connecting element 12 is connected to the drive end of the push driver 80. The adjustment mechanism 30 is rotatably mounted on the third connecting element 11 about a first axis. It is understood that the third connecting element 11 and the fourth connecting element 12 are connected by the elastic element 13, which can elastically deform along a second direction. When the tip 20 abuts against the workpiece, the elastic element 13 provides support force to the tip 20, which helps reduce the risk of the driving force of the push driver 80 directly acting on the tip 20, thereby reducing the risk of the workpiece being damaged by the pressure of the tip 20.

[0051] Specifically, in combination Figure 3 The elastic element 13 is a spring, the axis of which is set along the second direction. The two ends of the spring abut against the third connecting member 11 and the fourth connecting member 12 respectively. The fourth connecting member 12 is provided with a second guide rail assembly 952, which extends along the second direction. The third connecting member 11 is connected to the second guide rail assembly 952. The second guide rail assembly 952 can provide guidance for the movement of the third connecting member 11 relative to the fourth connecting member 12 along the second direction. The second pin hole 912 is opened on the third connecting member 11.

[0052] Please see Figure 1 This utility model provides a machining equipment, which includes a machining device and a center adjustment device 100. The machining device has a spindle and a machining mechanism. The spindle is used to clamp and fix the workpiece in conjunction with the center adjustment device 100, and the machining mechanism is used to machine the workpiece. Specifically, the machining equipment also includes a mounting surface parallel to the horizontal plane. The center adjustment device 100 is mounted on the mounting surface, and the spindle is mounted on one side of the center adjustment device 100 along a second direction. The spindle and the center adjustment device 100 are distributed on both sides of the workpiece machining position, and the machining device is located on one side of the workpiece machining position. By adding the center adjustment device 100 provided in this utility model to the machining equipment, the horizontal angle of the center 20 can be adjusted.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
