Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a convenient multi-directional adjustment fixture for CNC machine tools. Background Art

[0002] In current machining processes, workpieces often have multiple areas requiring machining. Operators frequently face situations where they need to remove the workpiece from the machining equipment, manually adjust its position, and then re-clamp it for machining. This traditional approach has several drawbacks: firstly, manually adjusting the workpiece position is tedious and time-consuming, significantly reducing overall machining efficiency; secondly, because the position adjustment relies entirely on the operator's visual inspection and experience, this imprecise positioning method often fails to ensure that each machining area of ​​the workpiece is accurately aligned with the machining equipment, thus adversely affecting the machining accuracy of the workpiece. Utility Model Content

[0003] To address the problem that manual adjustment of the workpiece position in existing technologies can easily lead to insufficient machining accuracy, this utility model proposes a convenient multi-directional adjustment fixture for CNC machine tools.

[0006] Furthermore, a support rod is provided at the end of the flap away from the rotating rod, and the support rod abuts against or separates from the bottom inner wall of the cylinder box as the flap rotates around the rotating rod.

[0007] Furthermore, the bottom of the flap is provided with a sliding groove, and a movable block is provided on the piston rod of the first telescopic cylinder. The movable block is embedded in the sliding groove, and the movable block moves in the sliding groove along with the piston rod of the first telescopic cylinder.

[0008] Furthermore, the clamping component includes six second telescopic cylinders disposed on the turntable. Three second telescopic cylinders are disposed on each turntable, and two second telescopic cylinders form a group, for a total of three groups. Two second telescopic cylinders in the same group are symmetrically disposed on two turntables. Two clamping blocks are disposed on each of the two second telescopic cylinders in the same group. The two clamping blocks move closer to or further away from each other as the second telescopic cylinders move.

[0009] Furthermore, each second telescopic cylinder is also equipped with a third motor, which has a connecting plate. The clamping block is mounted on the connecting plate, and the third motor drives the clamping block to rotate.

[0024] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] A convenient multi-directional adjustable fixture for CNC machine tools includes a base 1, a motor housing 2 mounted on the base 1, a first motor 4 housed inside the motor housing 2, and a cylinder housing 3 connected to the first motor 4 mounted above the motor housing 2. The first motor 4 drives the cylinder housing 3 to rotate. A first telescopic cylinder 5 is mounted inside the cylinder housing 3, and a flap 6 is movably mounted above the cylinder housing 3. The piston rod of the first telescopic cylinder 5 is connected to the flap 6. A rotating shaft 15 is also mounted above the flap 6, with turntables 9 mounted at both ends of the rotating shaft 15. A second motor 8 is mounted on the side of the turntables 9 facing away from the rotating shaft 15, and the second motor 8 drives the rotating shaft 15 and the turntables 9 to rotate together. Multiple clamping components for clamping workpieces of different shapes are mounted on the two turntables 9.

[0026] Furthermore, one end of the flap 6 is rotatably connected to the upper end of the cylinder housing 3 via a rotating rod 62.

[0027] Furthermore, a support rod 7 is provided at the end of the flap 6 away from the rotating rod 62. The support rod 7 abuts against or separates from the bottom inner wall of the cylinder housing 3 as the flap 6 rotates around the rotating rod 62.

[0028] Furthermore, the bottom of the flap 6 is also provided with a sliding groove 61, and a movable block is provided on the piston rod of the first telescopic cylinder 5. The movable block is embedded in the sliding groove 61 and moves in the sliding groove 61 along with the movement of the piston rod of the first telescopic cylinder 5.

[0029] Furthermore, the clamping component includes six second telescopic cylinders 10 disposed on the turntable 9. Three second telescopic cylinders 10 are disposed on each turntable 9, and two second telescopic cylinders 10 are arranged as a group, for a total of three groups. Two second telescopic cylinders 10 in the same group are symmetrically disposed on two turntables 9. Two clamping blocks are disposed on the two second telescopic cylinders 10 in the same group, and the two clamping blocks move closer to or further away from each other as the second telescopic cylinder 10 moves.

[0030] Furthermore, each second telescopic cylinder 10 is also equipped with a third motor 11, and the third motor 11 is equipped with a connecting plate 16. The clamping block is installed on the connecting plate 16, and the third motor 11 drives the clamping block to rotate.

[0031] Furthermore, a circular block 17 is provided on the side of the connecting plate 16 facing the clamping block, and a cylinder 18 is provided on the clamping block. The circular block 17 is embedded in the cylinder 18, and a spring 19 connected to the circular block 17 is also provided inside the cylinder 18.

[0032] Furthermore, the shapes of the clamping blocks on the three sets of second telescopic cylinders 10 are all different, namely square clamping block 12, round clamping block 13 and triangular clamping block 14.

[0033] In a specific embodiment, such as Figures 1 to 5As shown, the convenient multi-directional adjustable fixture for CNC machine tools proposed in this application includes a base 1, a motor housing 2 above the base 1, a cylinder housing 3 above the motor housing 2, and a flip plate 6 above the cylinder housing 3. Mounting plates are mounted on both sides of the upper surface of the flip plate 6. There are two mounting plates, one on the left and one on the right. A turntable 9 is mounted on each mounting plate, and a rotating shaft 15 is positioned between the two turntables 9. A second motor 8 is mounted on the side of the turntable 9 facing away from the rotating shaft 15, driving the rotating shaft 15 to rotate. Since the two turntables 9 are fixed to both ends of the rotating shaft 15, the two turntables 9 rotate synchronously when the rotating shaft 15 rotates. Clamping components for holding the workpiece to be processed are mounted on the two turntables 9.

[0034] Here, a first motor 4 is installed inside the motor housing 2. The first motor 4 is connected to the bottom surface of the cylinder housing 3. When the first motor 4 is started, the cylinder housing 3 rotates above the motor housing 2, and the turntable 9 and the clamping parts on the turntable 9 also rotate. This design allows the orientation of the workpiece to be processed held by the clamping parts to be adjusted, and the workpiece to be processed can be rotated to the position required by the operator. The operator can adjust the direction without removing the workpiece, which not only simplifies the operation process, but also improves the processing accuracy of the workpiece compared with the traditional manual removal and adjustment of the workpiece.

[0035] In addition, if Figure 2 As shown, the left end of the flap 6 is rotatably mounted on the left side of the upper end of the cylinder housing 3 via a rotating rod 62. A support rod 7 is also provided on the right end of the flap 6 facing the cylinder housing 3. The length of the support rod 7 is the same as the depth of the cylinder housing 3. When the support rod 7 abuts against the bottom inner wall of the cylinder housing 3, the flap 6 remains horizontal at the top of the cylinder housing 3. Inside the cylinder housing 3, a first telescopic cylinder 5 is also provided. The first telescopic cylinder 5 is installed on the side of the cylinder housing 3 away from the rotating rod 62. A sliding groove 61 is also provided on the lower surface of the flap 6. A movable block is provided inside the sliding groove 61, and the piston rod of the first telescopic cylinder 5 is connected to the movable block. When the piston rod extends or retracts, it drives the movable block to move within the sliding groove 61. This design prevents the piston rod from getting stuck during extension or retraction, thus ensuring the reliability of the flap 6's movement. When the first telescopic cylinder 5 drives the piston rod to move, it lifts the right end of the flap 6, causing the flap 6 to rotate along the rotating rod 62. The height at which the flap 6 is lifted can be adjusted by controlling the length of the piston rod extending beyond the first telescopic cylinder 5. When the flap 6 is lifted, the turntable 9 on the flap 6 also moves accordingly. This design allows for adjustment of the height and tilt angle of the workpiece held by the clamping components, thus facilitating the processing of the workpiece.

[0036] Specifically, the clamping device includes two second telescopic cylinders 10 mounted on two turntables 9. Three second telescopic cylinders 10 are mounted on each turntable 9, for a total of six. It is important to note that the positions of the second telescopic cylinders 10 on the two turntables 9 are matched, with each pair of cylinders forming a group, for a total of three groups. The two cylinders 10 in each group are positioned on the left and right turntables 9 respectively. Each second telescopic cylinder 10 is equipped with a clamping block. The clamping blocks on the two cylinders 10 in the same group move closer together or separate as the cylinder 10 moves, thereby clamping the workpiece to be processed. It is worth mentioning that a third motor 11 is also provided on each second telescopic cylinder 10. A connecting plate 16 is provided on the third motor 11, and the clamping block is installed on the connecting plate 16. When the third motor 11 drives the connecting plate 16 to rotate, it drives the clamping block to rotate. Since the workpiece to be processed is firmly clamped by the clamping block, the workpiece to be processed can rotate with the rotation of the clamping block, thereby realizing the precise adjustment of the workpiece position and facilitating processing.

[0037] Furthermore, multiple circular blocks 17 are provided on the side of each connecting plate 16 facing the clamping block. Correspondingly, a cylinder 18 is provided on the clamping block to accommodate the circular blocks 17, and a spring 19 is also provided inside the cylinder 18. One end of the spring 19 is connected to the inner bottom of the cylinder 18, and the other end is connected to the circular block 17. Specifically, the elastic deformation of the spring 19 can absorb the impact force generated during the clamping process, thereby effectively reducing the direct impact on the workpiece to be processed, playing a buffering and protective role, and ensuring the safety and stability of the workpiece during the clamping process. The shapes of the clamping blocks provided on the three sets of second telescopic cylinders 10 are all different. The two second telescopic cylinders 10 of the first group are each provided with two square clamping blocks 12, the two second telescopic cylinders 10 of the second group are each provided with two circular clamping blocks 13, and the two second telescopic cylinders 10 of the third group are each provided with two triangular clamping blocks 14. By rotating the turntable 9, the positions of the clamping blocks of different shapes can be switched to clamp workpieces of different shapes.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
