Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a jacking device for milling machine equipment. Background Art

[0002] A milling machine is a machine tool that is mainly used to process planes, slots, gears, etc. of various parts. Milling is performed when there is relative motion between the rotating milling cutter and the workpiece.

[0003] During the processing, the existing milling machines usually use three axes to move to process the workpiece. When processing the inner wall of the annular workpiece, it is necessary to rotate a certain angle based on the Z axis to process the inner wall of the annular workpiece. However, the existing three-axis milling machines cannot rotate based on the Z axis, nor can they rotate the inner wall of the annular workpiece. The current method is to indirectly achieve the processing goal by adjusting the workpiece multiple times or using special fixtures, which not only increases the complexity of the operation, but also may affect the processing accuracy.

[0056] Please refer to Figure 1-Figure 3 An embodiment of the utility model provides a lifting device 100 for a milling machine, comprising:

[0057] A machining head assembly 110 is used for performing milling processing on a workpiece;

[0058] A two-way motion assembly 120, on which the processing head assembly 110 is disposed to drive the processing head assembly 110 to move along a first direction A and / or a second direction B;

[0059] The rotating assembly 130 is disposed on a side of the two-way motion assembly 120 away from the processing head assembly 110;

[0060] A lifting assembly 140 is disposed on a side of the rotating assembly 130 away from the two-way motion assembly 120 to drive the rotating assembly 130 to move along a third direction, wherein the first direction A is perpendicular to the second direction B and the third direction;

[0061] The rotating assembly 130 moves to drive the machining head assembly 110 to rotate along the axial direction of the lifting assembly 140 to perform rotary milling relative to the workpiece.

[0062] In this embodiment, since the rotating component 130 is arranged on the side of the two-way motion component 120 away from the processing head component 110; the lifting component 140 is arranged on the side of the rotating component 130 away from the two-way motion component 120 to drive the rotating component 130 to move along the third direction, the first direction A is perpendicular to the second direction B and the third direction, so that the processing head component 110 moves in the X and Y axis directions through the two-way motion component 120, and moves and rotates in the Z axis direction through the rotating component 130 and the lifting component 140.

[0063] The machining head assembly 110 is allowed to be precisely positioned and angle-adjusted in three-dimensional space, so that complex milling tasks can be performed, including but not limited to inner wall machining of an annular workpiece.

[0064] Precise control of the machining head assembly 110, especially fine adjustments in rotation and lifting, helps to improve the accuracy of the machining process and reduce machining errors.

[0065] Compared with the traditional method that requires multiple adjustments to the workpiece position or the use of special fixtures, the jacking device 100 for milling machine equipment simplifies the operation process and improves work efficiency.

[0066] The machining head assembly 110 is directly responsible for performing milling machining on the workpiece.

[0067] The machining head assembly 110 is mounted on a two-way motion assembly 120, allowing the machining head to move precisely in two directions (usually horizontal X-axis and Y-axis).

[0068] The rotating assembly 130 is located on the other side of the two-way motion assembly 120, and provides the processing head assembly 110 with a rotation capability, so that the processing head can rotate around the axis of the lifting assembly 140, which makes it possible to process complex shapes.

[0069] The lifting assembly 140 is located on the other side of the rotating assembly 130, and controls the movement of the rotating assembly 130 along a third direction (usually a vertical Z axis). The addition of the lifting assembly 140 provides adjustment capability along the Z axis, so that the processing head can adapt to workpieces of different heights, and also supports the rotation of the processing head around the Z axis.

[0070] In at least one embodiment of the present application, the rotating assembly 130 includes:

[0071] A rotating shaft 131, one end of which is disposed on the two-way motion assembly 120, and the other end of which is disposed on the lifting assembly 140;

[0072] The rotating motor 132 is rotatably connected to the rotating shaft 131 to drive the rotating shaft 131 to rotate around the axis of the lifting assembly 140 .

[0073] Please refer to Figure 1-Figure 6 In this embodiment, the rotation motor 132 is started to drive the rotation shaft 131 to rotate. The rotation shaft 131 transmits the power to the machining head assembly 110, so that the machining head can rotate around the axis of the lifting assembly 140. It is allowed to machine specific shapes and features by adjusting the rotation angle of the machining head while keeping the workpiece fixed, especially for complex workpieces that need to be rotated around a specific axis.

[0074] By directly rotating the machining head to adjust the machining angle instead of repositioning the workpiece, machining preparation time can be reduced and overall machining efficiency can be improved.

[0075] The use of the rotary motor 132 in combination with the rotary shaft 131 allows precise control of the rotation angle of the machining head, which helps to improve the accuracy during the machining process.

[0076] It is able to process workpieces at multiple angles and directions, expanding the processing range of the milling machine, especially for workpieces with complex shapes and special requirements that are difficult to process with traditional milling machines.

[0077] The rotating shaft 131 is a key part connecting the two-way motion assembly 120 and the lifting assembly 140, allowing the lifting assembly 140 to move in the vertical direction while realizing the rotation of the processing head. One end is connected to the two-way motion assembly 120 to ensure the freedom of movement in the X-axis and Y-axis, and the other end is connected to the lifting assembly 140 to ensure the movement and rotation capabilities in the Z-axis direction.

[0078] The rotating motor 132 is connected to the rotating shaft 131 and is responsible for driving the rotating shaft 131 to rotate. The function of the rotating motor 132 is to realize precise rotation control of the processing head. The rotation angle and speed of the processing head can be precisely adjusted through the speed and direction control of the motor.

[0079] The rotating motor 132 is a servo motor; the rotating shaft 131 is rod-shaped, and a protrusion is convexly provided on the outer peripheral surface of the rotating shaft 131.

[0080] In at least one embodiment of the present application, the lifting assembly 140 includes:

[0081] The telescopic member 141 is coaxially arranged with the rotating shaft 131;

[0082] The driving member 142 has one end of the telescopic member 141 disposed on the rotating shaft 131 and the other end thereof in transmission connection with the driving member 142 . The driving member 142 drives the telescopic member 141 to move along the third direction.

[0083] Please refer to Figure 1-Figure 6 In this embodiment, the activation of the driving member 142 drives the telescopic member 141 to telescope along the Z axis. This directly affects the vertical position of the processing head, thereby allowing the user to adjust the position of the processing head assembly 110 according to the different heights or processing depth requirements of the workpiece. The coaxial arrangement of the telescopic member 141 and the rotating shaft 131 ensures that the rotation ability of the processing head assembly 110 is not affected during the vertical movement, thereby achieving precise adjustment in the vertical direction and flexible control in the rotation direction.

[0084] By precisely controlling the vertical position of the machining head, higher machining accuracy and quality can be achieved, especially when processing complex workpieces or performing fine machining.

[0085] Users can easily adjust the vertical position of the processing head without complicated manual adjustments or the use of special tools, thus simplifying the operation process and improving work efficiency.

[0086] The introduction of the lifting assembly 140 reduces the need for manual adjustments, which not only speeds up production but also improves the safety of the operation process.

[0087] The combined use of the telescopic member 141 and the driving member 142 coaxial with the rotating shaft 131 provides the milling machine with the dual functions of vertical movement and rotation, enabling the machine tool to handle more complex and diverse processing tasks.

[0088] The telescopic member 141 is coaxially arranged with the rotating shaft 131 , so that the telescopic member 141 can maintain synchronization with the rotating shaft 131 when performing vertical movement or adjustment, thereby ensuring the coordination and consistency of the rotation and lifting movement of the processing head.

[0089] One end of the telescopic member 141 is connected to the rotating shaft 131, and the other end is in transmission connection with the driving member 142. The driving member 142 is used to drive the telescopic member 141 to move along a third direction (usually a vertical direction, i.e., the Z axis), allowing the lifting assembly 140 to achieve precise vertical positioning of the processing head to meet the processing requirements of different heights.

[0090] The driving member 142 and the telescopic member 141 form an electric cylinder.

[0091] In at least one embodiment of the present application, the lifting device for a milling machine further comprises:

[0092] The fixing platform 150 has a fixing surface 150 a , and a connecting hole 150 b is opened at the center of the fixing surface 150 a . One end of the rotating shaft 131 passes through the connecting hole 150 b and is fixed to the two-way motion component 120 .

[0093] Please refer to Figure 1-Figure 6 In this embodiment, during the operation of the milling machine, the fixed table 150 serves as a basic platform to provide stable support for the entire jacking device. The rotating shaft 131 passes through the fixed table 150 through the connecting hole 150b and is fixedly connected to the two-way motion component 120. The rotating shaft 131 can transmit power and motion while maintaining stability, allowing the processing head to perform precise linear and rotational motion along a predetermined path. The presence of the fixed table 150 ensures the symmetry and balance of the entire mechanism, which helps to maintain the stability and accuracy of the machine tool during high-speed motion and complex operations.

[0094] By mounting the lifting device on the fixed platform 150 , the entire lifting device is kept stable during operation, thereby reducing processing errors caused by vibration or imbalance.

[0095] This ensures that the rotating shaft 131 and the machining head assembly 110 can accurately move and rotate along a predetermined path, thereby improving machining accuracy.

[0096] The fixed platform 150 is an important component of the lifting device, providing a stable platform to support the operation of the entire mechanism.

[0097] A connecting hole 150 b is provided at the geometric center of the fixing surface 150 a so that the rotating shaft 131 can pass through the fixing platform 150 and thus be connected to the two-way motion assembly 120 .

[0098] After one end of the rotating shaft 131 passes through the connecting hole 150b, it is fixed to the two-way motion assembly 120. This not only ensures the stability of the rotating shaft 131, but also ensures the precise movement and rotation of the processing head assembly 110.

[0099] In at least one embodiment of the present application, the rotating assembly 130 further includes:

[0100] A rotating member 133 is rotatably connected to the rotating motor 132, and a connecting hole 133a and a limiting hole 133b communicating with the connecting hole 133a are formed on the rotating member 133;

[0101] A limiting convex portion 1311 is protruded from the outer circumference of the rotating shaft 131, the rotating shaft 131 passes through the connecting hole 133a, and the limiting convex portion 1311 is received in the limiting hole 133b;

[0102] When the rotating member 133 drives the rotating shaft 131 to rotate, the limiting protrusion 1311 prevents the rotating shaft 131 from rotating relative to the rotating member 133 .

[0103] Please refer to Figure 1-Figure 6 In this embodiment, during the operation of the milling machine, the rotating motor 132 is started and drives the rotating member 133 to rotate. The limiting protrusion 1311 ensures that the rotating shaft 131 can accurately move synchronously with the rotating member 133 during rotation, avoiding any relative sliding or displacement, and ensuring the accuracy and stability of the rotation.

[0104] By using the limiting protrusion 1311 in conjunction with the limiting hole 133 b , accurate synchronization between the rotating shaft 131 and the rotating member 133 can be ensured, thereby avoiding errors during the movement process.

[0105] The limiting protrusion 1311 reduces the mechanical wear caused by the relative movement between the rotating shaft 131 and the rotating member 133, thereby extending the service life of the device.

[0106] The rotating member 133 is rotatably connected to the rotating motor 132 and serves as an intermediate component for transmitting the rotating power. The connecting hole 133a and the limiting hole 133b ensure the accurate positioning and stability of the rotating shaft 131.

[0107] The connecting hole 133 a on the rotating member 133 allows the rotating shaft 131 to pass through, and the limiting hole 133 b connected to the connecting hole 133 a is used to accommodate the limiting protrusion 1311 on the rotating shaft 131 to ensure the synchronous movement between the rotating shaft 131 and the rotating member 133 .

[0108] The limiting protrusion 1311 protrudes from the outer circumference of the rotating shaft 131 and penetrates through the connecting hole 133a and is received in the limiting hole 133b, so as to prevent the rotating shaft 131 from being displaced relative to the rotating member 133 during rotation.

[0109] The rotating member 133 is meshed with the rotating motor 132 via gears, so that the output torque of the rotating motor 132 is transmitted to the rotating member 133 , and the rotating member 133 is driven to rotate around the axis of the rotating shaft 131 .

[0110] In at least one embodiment of the present application, a mounting position 150c is formed on a side of the fixed platform 150 away from the processing head assembly 110, the rotating motor 132 and the rotating member 133 are arranged on the mounting position 150c, and the mounting position 150c is connected to the connecting hole 150b.

[0111] Please refer to Figure 1-Figure 6 In this embodiment, during the operation of the milling machine, the rotary motor 132 is started on the mounting position 150c, and transmits power to the rotary shaft 131 through the rotating member 133. Due to the direct connection between the mounting position 150c and the connecting hole 150b, it can be ensured that the rotary shaft 131 and the processing head assembly 110 thereon can be accurately rotated and positioned as required.

[0112] By centrally arranging the rotating motor 132 and the rotating member 133 on the mounting position 150c of the fixed platform 150, space utilization is optimized, making the device more compact and neat.

[0113] The direct connection between the mounting position 150c and the connecting hole 150b simplifies the power transmission path, reduces energy loss and motion error, and improves the accuracy and reliability of operation.

[0114] The rotating motor 132 and the rotating member 133 are placed on the mounting position 150 c of the fixed platform 150 , which helps to simplify the mechanical structure and makes the connection between the motor and the rotating member 133 more direct and efficient.

[0115] The mounting position 150c is directly connected to the communication hole 150b in the fixing table 150, thereby ensuring that the rotating motor 132 and the rotating member 133 can directly affect the rotating shaft 131 passing through the communication hole 150b, thereby driving the processing head assembly 110 to perform the required rotation and position adjustment.

[0116] In at least one embodiment of the present application, the rotating assembly 130 further includes:

[0117] An auxiliary member 134 is disposed on a side of the rotating member 133 close to the processing head assembly 110 , and the auxiliary member 134 is provided with a rotating hole 134 a;

[0118] A rotating portion 1312 is disposed at one end of the rotating shaft 131 close to the processing head assembly 110 . The rotating portion 1312 is movably received in the rotating hole 134 a .

[0119] Please refer to Figure 1-Figure 6 In this embodiment, when the milling machine starts to operate, the rotary motor 132 drives the rotary member 133 (including the auxiliary member 134 and the rotary portion 1312) to rotate. The rotary shaft 131 cooperates with the rotary hole 134a of the auxiliary member 134 through its rotary portion 1312, thereby achieving stable and precise rotary motion. The rotary shaft 131 is allowed to maintain precise alignment with the machining head assembly 110 during rotary machining, thereby ensuring high precision and high stability of the machining process.

[0120] Through the precise matching of the auxiliary component 134 and the rotating portion 1312 , the stability and alignment of the rotating shaft 131 during rotation can be ensured, thereby improving the processing accuracy.

[0121] The introduction of the auxiliary member 134 increases the stability of the entire system and reduces vibrations and errors caused by unstable bearing movement.

[0122] The auxiliary member 134 and the rotating portion 1312 help extend the service life of the equipment by reducing unnecessary wear and improving the stability of the overall system.

[0123] The auxiliary member 134 is cylindrical and has a stepped hole therein.

[0131] In at least one embodiment of the present application, the processing head assembly 110 includes:

[0132] A driving motor 111 is provided on the first moving block 1213;

[0133] The machining cutter head 112 is disposed at the output end of the driving motor 111 .

[0134] Please refer to Figure 1-Figure 6 In this embodiment, when the milling machine is started, the first motor 1211 and the second motor 1221 respectively drive the first screw rod 1212 and the second screw rod 1222 to rotate, and drive the first moving block 1213 and the second moving block 1223 to move along two perpendicular directions through the transmission mechanism.

[0135] This enables the machining head assembly 110 to be accurately positioned at any position within the plane. The driving motor 111 then drives the machining cutter head 112 to rotate and perform the required milling operation.

[0136] The milling machine can accurately control the position of the processing head on two planes, greatly improving the processing accuracy and flexibility.

[0138] The first moving assembly 121 is composed of a first motor 1211, a first screw rod 1212 and a first moving block 1213 connected thereto. The first moving block 1213 is fixedly connected to the processing head assembly 110, ensuring that the processing head assembly 110 moves with the movement of the first moving assembly 121.

[0142] The first motor 1211 is started to drive the first screw rod 1212 to rotate.

[0143] The rotation of the first screw rod 1212 is converted into linear motion through the first moving block 1213 which is transmission-connected thereto.

[0144] The first moving block 1213 moves along the first direction A. Since the first moving block 1213 is fixedly connected to the processing head assembly 110 , the processing head assembly 110 also moves along the first direction A.

[0145] Movement in the second direction B (e.g. Y axis):

[0146] The second motor 1221 is started to drive the second screw rod 1222 to rotate.

[0147] The rotation of the second screw rod 1222 is also converted into linear motion through the second moving block 1223 transmission-connected thereto.

[0148] The second moving block 1223 moves along the second direction B. Since the second moving block 1223 is fixedly connected to the first motion assembly 121 , the entire processing head assembly 110 moves along the second direction B.

[0149] Movement in the third direction (such as the Z axis):

[0150] The driving member 142 (which may be a motor or other driving mechanism) of the lifting assembly 140 is started to drive the telescopic member 141 (such as a guide rod or a screw rod) to move along the third direction.

[0151] The movement of the telescopic member 141 adjusts the height of the rotating assembly 130 (including the processing head assembly 110 ), so that the processing head can adapt to workpieces of different heights or perform depth-controlled processing tasks.

[0152] Rotational motion of the rotating assembly 130:

[0153] The rotating motor 132 is started, and drives the rotating shaft 131 to rotate through the rotating member 133 (including gears, belts or direct connection).

[0154] The rotation of the rotating shaft 131 drives the machining head assembly 110 (especially the machining tool head 112 ) to rotate, allowing rotary milling processing to be performed.

[0155] Thus, a lifting device 100 for a milling machine is provided, comprising:

[0156] A machining head assembly 110 is used for performing milling processing on a workpiece;

[0157] A two-way motion assembly 120, on which the processing head assembly 110 is disposed to drive the processing head assembly 110 to move along a first direction A and / or a second direction B;

[0158] The rotating assembly 130 is disposed on a side of the two-way motion assembly 120 away from the processing head assembly 110;

[0159] A lifting assembly 140 is disposed on a side of the rotating assembly 130 away from the two-way motion assembly 120 to drive the rotating assembly 130 to move along a third direction, wherein the first direction A is perpendicular to the second direction B and the third direction;

[0160] The rotating assembly 130 moves to drive the machining head assembly 110 to rotate along the axial direction of the lifting assembly 140 to perform rotary milling relative to the workpiece.

[0161] In this embodiment, since the rotating component 130 is arranged on the side of the two-way motion component 120 away from the processing head component 110; the lifting component 140 is arranged on the side of the rotating component 130 away from the two-way motion component 120 to drive the rotating component 130 to move along the third direction, the first direction A is perpendicular to the second direction B and the third direction, so that the processing head component 110 moves in the X and Y axis directions through the two-way motion component 120, and moves and rotates in the Z axis direction through the rotating component 130 and the lifting component 140.

[0162] The machining head assembly 110 is allowed to be precisely positioned and angle-adjusted in three-dimensional space, so that complex milling tasks can be performed, including but not limited to inner wall machining of an annular workpiece.

[0163] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
