Description

Technical Field

[0001] This invention relates to the field of machine tool processing technology, and in particular to a method for processing an adjustable angle golf club shank. Background Technology

[0002] In golf clubs, loft generally refers to the angle between the center line of the clubface and the vertical line to the ground when the club is at rest. It reflects the degree of tilt of the clubface when it contacts the golf ball at impact. Loft significantly affects the ball's flight path, trajectory, backspin, and spin (when the shot is off-target). Modern golf clubs are generally made as separate clubs consisting of a grip, a shaft with adjustable angle, and a clubhead. The connection angle between the shaft and the clubhead is adjustable.

[0003] The tube handle assembly mainly consists of a tube handle and connecting screws, such as Figure 3 The illustrated tube handle 3 includes a threaded head 30 and an inner bore head 31. One end of the threaded head 30 has an internal threaded hole 302 for threaded connection with the handle rod connection end. One end of the inner bore head 31 has an mounting inner hole 312 for inserting a ball head and engaging with a connecting screw for connection and fixation. (See reference) Figure 3 The internal threaded hole 302 of the pipe handle 3 has an angle α with the central axis of the mounting inner hole 312. Different pipe handles 3 can be designed with different angles.

[0004] The handle is generally made of aluminum alloy through machining and surface oxidation laser engraving. The main processes include turning the outer diameter, milling the wrench position, marking the marking points, turning the cap head and inner hole, tapping, oxidation, and laser engraving. Among these, turning the outer diameter, milling the wrench position, marking the marking points, turning the cap head and inner hole, and tapping are the main machining processes completed on machine tools. Traditional machining methods require different machine tools to complete each machining process, that is, multiple machine tools need to process in sequence to complete the machining of the part. The flow of the workpiece between multiple processes not only makes the work-in-process occupy a high rate of machine tool usage, but also requires the use of multiple clamping fixtures to control the errors caused by multiple clamping, which inevitably increases auxiliary time. In addition, it is difficult to ensure the quality of the parts such as machining accuracy, and the production efficiency is low when mass production. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a machining method for an adjustable angle golf club handle, which features fewer clamping operations, higher precision, and higher efficiency in the machining process.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows:

[0007] A method for machining an adjustable-angle golf club shank includes a machine tool support, a first spindle movable along the X-axis mounted on the machine tool support, a second spindle movable along the X-axis mounted on the machine tool support, a first turret movable along the X, Z, and Y axes mounted on the machine tool support, and a second turret movable along the X, Z, and Y axes mounted on the machine tool support; the first spindle is equipped with a first clamping device capable of clamping a workpiece or a cutting tool, the second spindle is equipped with a second clamping device capable of clamping a workpiece or a cutting tool, the rotation axis of the first spindle coincides with the rotation axis of the second spindle, the first turret is equipped with a first cutting disc capable of rotating to switch between different cutting tools, and the second turret is equipped with a second cutting disc capable of rotating to switch between different cutting tools;

[0008] The machining steps for the tube handle are as follows:

[0009] S1: The first clamping device clamps the left end of the cylindrical workpiece, the first tool disc is installed and switched to an external turning tool, the first tool turret is adjusted to an appropriate position along the X-axis, Z-axis and Y-axis, the first spindle drives the cylindrical workpiece to rotate along the C-direction, and the external turning tool processes the right end face of the cylindrical workpiece to make it flat.

[0010] S2: The second clamping device is first replaced with a center drill. The second spindle drives the center drill to rotate and simultaneously advances to the left on the X-axis to process the center of the right end face of the cylindrical workpiece to form a guide hole. The second clamping device is then replaced with a twist drill. The second spindle drives the twist drill to rotate and simultaneously advances to the left on the X-axis to process the guide hole in S1 to form a smooth hole.

[0011] S3: The second clamping device is fitted with a tap, and the second spindle drives the tap to rotate while advancing to the left on the X-axis to process the smooth hole and form the internal thread hole at the right end of the tube handle;

[0012] S4: Adjust the external turning tool on the first tool turret, adjust the first tool turret to the appropriate position along the X-axis, Z-axis and Y-axis, and rotate the first spindle along the C direction while adjusting its position in the X-axis direction to process the outer cylindrical surface of the cylindrical workpiece, forming the first right outer diameter of the tube handle, the second right outer diameter of the tube handle, the first chamfer between the first right outer diameter of the tube handle and the second right outer diameter of the tube handle, and the second chamfer on the right end face;

[0013] S5: The first tool disc is installed and switched to a milling cutter. The rotation axis of the milling cutter is perpendicular to the rotation axis of the first spindle. The milling cutter rotates to process the outer circular surface on the left side of the outer circle of the first right tube. The first spindle advances on the X-axis to form a strip-shaped groove on the outer circular surface. After each strip-shaped groove is processed, the first spindle rotates a certain angle to form several uniformly spaced wrench positions with strip-shaped grooves on the circumference of the tube handle.

[0014] S6: The first clamping device releases the workpiece, the second clamping device clamps the outer diameter of the first right tube, the second spindle rotates, the second tool disc is installed and switched to the external turning tool, the second turret is adjusted to the appropriate position along the X-axis, Z-axis and Y-axis, and the left end face of the wrench position and the outer diameter surface on the left side of the wrench position are machined to form the outer diameter of the left tube of the handle and the conical outer diameter.

[0015] S7: A center drill and a twist drill are mounted on the first tool disc. The first tool turret is adjusted to a suitable position along the X-axis, Z-axis and Y-axis. The first tool disc is rotated to switch tools, so that the rotation axis of the center drill or twist drill forms an angle α with the central axis of the conical outer circle. The center drill or twist drill rotates, and the first tool turret advances along the X-axis and Y-axis towards the workpiece to process the left end face of the conical outer circle to form a light hole. The central axis of the light hole forms an angle α with the central axis of the conical outer circle.

[0016] S8: A reamer is installed on the first tool disc. The first tool turret is adjusted to a suitable position. The first tool disc is rotated to switch tools, so that the rotation axis of the reamer forms an angle α with the central axis of the conical outer circle. The reamer rotates and advances and processes along the central axis of the light hole in S7 to form the mounting inner hole of the pipe handle. The central axis of the mounting inner hole forms an angle α with the central axis of the internal thread hole.

[0017] The first spindle is mounted on a first track platform that can move along the X-axis. The first track platform is equipped with a first spindle motor that drives the first spindle to rotate and a first track motor that drives the first track platform to move along the X-axis.

[0018] The second spindle is mounted on a second track platform that can move along the X-axis. The second track platform is equipped with a second spindle motor that drives the second spindle to rotate and a second track motor that drives the second track platform to move along the X-axis.

[0019] The first turret includes a first tool disc support, the first tool disc is rotatably disposed on the right side of the first tool disc support, and a tool position for mounting tools is provided on the outer circumference of the first tool disc;

[0020] The second turret includes a second tool disc support. The second tool disc is rotatably disposed on the left side of the second tool disc support. Several tool positions for mounting tools are provided on the outer circumference of the second tool disc.

[0021] The tool position is detachably mounted with an external turning tool and several drive units. The center drill, twist drill, milling cutter, or reamer can be mounted on the drive unit, and the drive unit can drive the center drill, twist drill, milling cutter, or reamer to rotate.

[0022] The first turret and the second turret are mounted on the same tool holder slide rail platform. The first turret and the second turret can move along the X-axis on the tool holder slide rail platform, and the tool holder slide rail platform can move along the Y-axis and the Z-axis.

[0023] In step S4, the outer circle of the first right tube and the outer circle of the second right tube (301) form a stepped axis, and the diameter of the outer circle of the first right tube is larger than that of the outer circle of the second right tube.

[0024] In step S5, the wrench position of the pipe handle forms 6-8 strip-shaped grooves.

[0025] Preferably, step S60 is performed after step S6 and before step S7:

[0026] After the external turning tool finishes machining the tapered outer circle, the posture of the external turning tool is adjusted to machine the left end face of the tapered outer circle, forming an end face chamfer.

[0027] Preferably, step S9 is performed after step S8:

[0028] The first tool turret is equipped with a boring bar. The boring bar rotates and the first turret controls the boring bar to advance towards the central axis of the mounting inner hole to machine the left end face of the mounting inner hole and form the inner hole chamfer.

[0029] The beneficial effects of this invention are:

[0030] 1. Improved processing efficiency. This processing method completes the machining of the tube handle on a single machine tool. From blank to finished product, the workpiece is processed by the lateral movement of the first and second spindles along the X-axis and the flexible movement of the first and second turrets along the X, Z, and Y axes to adjust the position of the workpiece and the cutting tool, thus completing all machining operations. This reduces the machine tool's footprint and, compared to traditional methods involving multiple intermediate transfers and manual clamping, shortens the production cycle and improves processing efficiency.

[0031] 2. It possesses good convenience and applicability. The internal threaded hole of the pipe shank has an offset angle α between its central axis and the mounting inner hole. This offset angle α is achieved by adjusting the axial offset angle between the rotation axes of the center drill, twist drill, and reamer on the first tool turret and the central axis of the pipe shank in steps S7 and S8. More specifically, the offset between the rotation axis of the rotating tool and the central axis of the pipe shank can be achieved by adjusting the mounting posture of the drive unit on the first tool turret. During machining, the first tool turret controls the rotating tool to advance along its rotation axis. The movement and advance of the first tool turret in the X, Y, and Z axes are controlled by servo motors. Several drive units can be installed at different tool positions on the first tool turret according to the requirements of the machining steps, and different rotating tools can be installed on the drive units. The offset angle α can be adjusted by adjusting the mounting posture of the drive unit to achieve the axial offset angle between the rotation axis of the rotating tool and the central axis of the pipe shank, which is relatively convenient and can meet the machining requirements of pipe shanks with different offset angles, thus possessing good convenience and applicability.

[0032] 3. Ensure product quality. During the machining process, the workpiece is clamped only twice, which is significantly less than traditional machining methods. This reduces errors caused by fewer clamping operations, ensuring machining accuracy and improving product quality.

[0033] 4. Cost savings and simplified processing. Reduced labor input and equipment usage lower production costs. Attached Figure Description

The first tool turret 41 is adjusted to an appropriate position along the X-axis, Z-axis, and Y-axis. The first spindle 211 rotates along the C-axis and is simultaneously adjusted to its position in the X-axis direction. At the same time, the external turning tool 50 is adjusted to its posture mounted on the tool position 40 to machine the outer cylindrical surface of the cylindrical workpiece, forming the first right outer diameter 300, the second right outer diameter 301, the first chamfer 303 between the first right outer diameter 300 and the second right outer diameter 301, and the second chamfer 304 on the right end face of the pipe handle 3. Preferably, the angles of the first chamfer 303 and the second chamfer 304 are 45°. Further, referring to... Figure 3 The outer circle 300 of the first right tube and the outer circle 301 of the second right tube form a stepped axis, and the diameter of the outer circle 300 of the first right tube is larger than that of the outer circle 301 of the second right tube.

[0061] S5: Reference Figure 8 The first tool disk 411 is equipped with and switched to a milling cutter 53. At this time, the rotation axis of the milling cutter 53 is perpendicular to the rotation axis of the first spindle 211. The milling cutter 53 rotates to process the outer surface of the left side of the outer diameter 300 of the first right tube. The first spindle 211 advances on the X-axis to form a strip groove on the outer surface. After each strip groove is processed, the first spindle 211 rotates a certain angle to form a wrench position 306 with several uniform strip grooves on the circumference of the tube handle 3.

[0063] Preferably, step S60 is performed after step S6:

The first tool turret 41 is adjusted to a suitable position along the X-axis, Z-axis and Y-axis. The first tool disk 411 rotates to switch tools, so that the rotation axis of the center drill or twist drill 51 forms an angle α with the central axis of the conical outer circle 311. The center drill or twist drill 51 rotates, and the first tool turret 41 can move and advance along the X-axis, Y-axis and Z-axis to process the left end face of the conical outer circle (311) to form a light hole.

[0068] Furthermore, there is an angle α between the internal threaded hole 302 of the pipe handle 3 and the central axis of the mounting inner hole 312. This angle α is achieved by adjusting the axis of rotation of the center drill, twist drill 51, and reamer 54 on the first tool disk 411 in steps S7 and S8, so as to achieve the axial angle between the axis of rotation of the rotating tool and the central axis of the pipe handle 3. The offset between the axis of rotation of the rotating tool and the central axis of the pipe handle 3 can be achieved by adjusting the mounting posture of the drive unit 55 on the first tool disk 411. During the machining process, the first tool turret 41 controls the rotating tool to advance along the axis of rotation of the tool. The movement and advance of the first tool turret 41 on the X-axis, Y-axis and Z-axis are controlled by servo motors. Several drive units 55 can be installed on different tool positions on the first tool disk 411 according to the requirements of the machining steps, and different rotary tools can be installed on the drive units 55.

The boring bar rotates, and the first tool turret 41 controls the boring bar to advance towards the central axis of the mounting inner hole 312 to machine the left end face of the mounting inner hole 312, forming the inner hole chamfer 3120 of the mounting inner hole 312.

[0071] Furthermore, threaded holes are evenly distributed on the circumference of the outer diameter 310 of the left tube of the handle 3. When the inner hole 312 is inserted into the golf head assembly, the connecting screw is tightened from the threaded hole to achieve the fit between the handle 3 and the golf head assembly.
