[0011] This automotive suspension control arm drilling and boring combined machining device includes a bed 1, a transverse sliding seat 6, a power head A7, a power head B10, a drill bit 9, and a boring tool 11 (see the instruction manual appendix). Figure 1 and 2 ).

[0012] A longitudinal slide block 3 is slidably mounted on the middle of the bed 1 via a longitudinal slide rail 2. A longitudinal lead screw 5 is mounted on the bed 1 below the longitudinal slide block 3 via a servo motor 4; the longitudinal lead screw 5 is connected to the longitudinal slide block 3. During operation, the servo motor 4 drives the longitudinal lead screw 5 to rotate forward and backward, thereby pushing the longitudinal slide block 3 to slide back and forth along the longitudinal slide rail 2.

[0013] The longitudinal sliding seat 3 is equipped with a clamping assembly (see the instruction manual). Figure 1 and 2The clamping assembly includes two sets of transverse clamping seats 13 and one set of longitudinal clamping seats 14; a set of longitudinal clamping seats 14 is mounted on the longitudinal sliding seat 3; two sets of transverse clamping seats 13 are symmetrically mounted on the longitudinal sliding seat 3 on one side of the longitudinal clamping seat 14 (see the appendix to the instruction manual). Figure 1 and 2 ).

[0014] Both the longitudinal clamping seat 14 and the transverse clamping seat 13 include a support plate 15, a rotary pressing cylinder 16, and a support block 17 (see the attached instruction manual). Figure 2 and 3 The longitudinal sliding seat 3 is equipped with a support plate 15; the support plate 15 is equipped with a support block 17; the support block 17 is provided with a V-shaped support opening 19 (see the instruction manual appendix). Figure 3 ).

[0015] A clamping block 18 is mounted on the support plate 15 above the support block 17 via a rotating pressing cylinder 16 (see instruction manual appendix). Figure 3 During operation, the workpiece (automotive suspension control arm) can be placed on the support blocks 17 of the longitudinal clamping seat 14 and the transverse clamping seat 13. Then, the downward pressing cylinder 16 is rotated to drive the clamping block 18 to clamp and fix the workpiece in cooperation with the support block 17. In this process, the assembly 20 of the workpiece (automotive suspension control arm) is placed on the support block 17 of the transverse clamping seat 13, and the clamping block 18 of the transverse clamping seat 13 clamps and fixes the assembly 20 in cooperation with the support block 17.

[0016] Four sets of transverse slide seats 6 are slidably mounted on the bed 1 on both sides of the longitudinal slide seat 3 via transverse slide rails. A transverse lead screw 12 is mounted on the bed 1 below the transverse slide seats 6 via a servo motor 4; the transverse lead screw 12 is connected to the transverse slide seat 6 (see the instruction manual appendix). Figure 1 and 2 When the servo motor 4 is working, it can drive the transverse sliding seat 6 to slide back and forth along the transverse slide rail by rotating the transverse lead screw 12 in both directions.

[0017] Two sets of transverse sliding seats 6, located in the same transverse direction, are equipped with drill bits 9 via power heads A7 and chucks 8; the other two sets of transverse sliding seats 6, located in the same transverse direction, are equipped with boring tools 11 via power heads B10 and chucks 8.

[0018] Both power head A7 and power head B10 are existing purchased equipment, model BT50. When power head A7 rotates, it can drive drill bit 9 to rotate synchronously; when power head B10 rotates, it can drive boring tool 11 to rotate synchronously.

[0019] The CNC system of this automotive suspension control arm drilling and boring composite machining device is provided by Taiwan's Syntec. During operation, it can control each component to move sequentially according to the program.

[0020] When the car suspension control arm drilling and boring composite machining device is working, the workpiece to be processed (car suspension control arm) is first placed on the support block 17 of the longitudinal clamping seat 14 and the transverse clamping seat 13. Then, the rotating pressing cylinder 16 drives the clamping block 18 to clamp and fix the workpiece in cooperation with the support block 17.

[0021] After the workpiece is clamped and fixed, the servo motor 4 pushes the longitudinal sliding seat 3 through the longitudinal lead screw 5, so that when the center of the workpiece assembly 20 on the longitudinal sliding seat 3 corresponds to the drill bit 9, the longitudinal sliding seat 3 stops moving.

[0022] Subsequently, the power head A7 drives the drill bit 9 to rotate. During the rotation of the drill bit 9, the servo motor 4 drives the corresponding transverse sliding seat 6 to move through the transverse lead screw 12, causing the power head A7 to drive the rotating drill bit 9 closer to the workpiece assembly 20, thus completing the drilling action. After the drill bit 9 completes the drilling action, the transverse sliding seat 6 drives the power head A7 to retract and reset.

[0023] After the above work is completed, the servo motor 4 pushes the longitudinal sliding seat 3 through the longitudinal lead screw 5, so that the center of the workpiece assembly 20 on the longitudinal sliding seat 3 corresponds to the boring tool 11; at this time, the longitudinal sliding seat 3 stops moving.

[0024] Subsequently, the power head B10 drives the boring bar 11 to rotate; during the rotation of the boring bar 11, the servo motor 4 drives the corresponding transverse sliding seat 6 to move through the transverse lead screw 12, so that the power head B10 drives the rotating boring bar 11 to approach the workpiece assembly 20, and completes the boring action.

[0025] After the boring operation is completed, the servo motor 4 drives the corresponding transverse sliding seat 6 via the transverse lead screw 12, which in turn drives the power head B10 to reset. Then the longitudinal sliding seat 3 resets, and a new workpiece is then placed on top, allowing the drilling and boring machine for the automotive suspension control arm to enter the next work cycle.

[0026] This automotive suspension control arm drilling and boring composite machining device can change the installation position of the power head A7 on the lateral sliding seat 6 and the installation position of the power head B10 on the lateral sliding seat 6 as needed when machining different models of automotive suspension control arms, so as to meet the production needs of different models of automotive suspension control arms.

[0027] The automotive suspension control arm drilling and boring composite machining device has a compact structure and ingenious design. It can complete the drilling and boring of the automotive suspension control arm in a single clamping, which solves the problem of low efficiency in the existing drilling and boring machining methods for automotive suspension control arms. It is particularly suitable for the needs of automotive suspension control arm machining.
