[0025] As Figure 1 and Figure 2 shown, the present utility model proposes a fixture for machining automotive parts.

[0026] In an exemplary embodiment, the fixture for machining automotive parts includes:

[0027] A bottom plate 1;

[0028] A clamping mechanism, arranged on the bottom plate 1. The clamping mechanism includes a fixed component and a moving component, and a placement position for placing parts is provided between the fixed component and the moving component;

[0029] A driving mechanism, arranged on the bottom plate 1. The output end of the driving mechanism is connected to the moving component, and the driving mechanism is used to drive the moving component to approach or move away from the fixed component.

[0030] In this embodiment, through the provided moving component and fixing component, after the component is installed at the placement position, through the cooperation between the moving component and the fixing component, the component can be firmly fixed at the placement position. During the clamping process, the movement of the moving component is realized through the driving mechanism, and the clamping force can be freely adjusted, ensuring the firmness of the component clamping and improving the processing quality of the workpiece 16.

[0031] In this embodiment, the placement position is between the moving component and the fixing component. During the specific processing process, the workpiece 16 to be processed is installed at the placement position, and then the workpiece 16 can be fixed by clamping through the clamping mechanism. When the moving component approaches the fixing component, the workpiece 16 is clamped, and when the moving component moves away from the fixing component, the workpiece 16 is loosened, and the workpiece 16 can be taken out.

[0032] It should be noted that the bottom plate 1 in this embodiment is mainly used to connect with the workbench of the machine tool, and bolts and other fasteners are used for fixing during the connection.

[0033] In an exemplary embodiment, the moving component includes a driving block 5. On the side of the driving block 5 close to the fixing component, there is a moving clamping block 7. On the moving clamping block 7, there is a pushing portion 9, and the pushing portion 9 is used to contact the component and drive the component to approach the fixing component.

[0034] In this embodiment, the output end of the driving mechanism drives the driving block 5 to move. The driving block 5 will drive the moving clamping block 7 to move synchronously. The pushing portion 9 of the moving clamping block 7 will contact the workpiece 16, and finally push the workpiece 16 to the fixing component to realize the stable fixing of the workpiece 16.

[0035] Exemplarily, the moving clamping block 7 is detachably connected to the driving block 5, specifically connected by bolts or screws. On the moving clamping block 7, there is an avoidance groove 8 for avoiding the protruding part of the component. The avoidance groove 8 is located between the pushing portions 9. The moving clamping block 7 is integrally "L"-shaped, connected to the driving block 5 in the vertical direction, and the avoidance groove 8 is opened in the horizontal direction. And the avoidance groove 8 in this embodiment can be adaptively set according to the shape of the workpiece 16. When processing different parts, the moving clamping block 7 can be replaced for clamping, improving the applicable range of the present utility model.

[0036] Exemplarily, in this embodiment, the number of the pushing portions 9 is two, located on the front and rear sides of the avoidance groove 8, aiming to increase the contact area between the moving clamping block 7 and the workpiece 16, being able to drive the workpiece 16 to move quickly and stably, and during clamping, multiple pushing portions 9 can also improve the clamping stability.

[0037] In an exemplary embodiment, the fixing component includes a positioning seat 11. The positioning seat 11 is arranged on the bottom plate 1, and on the side of the positioning seat 11 close to the moving component, there is a fixed clamping block 12.

[0038] In this embodiment, by providing the positioning seat 11 and the fixed clamping block 12 provided on the positioning seat 11, the workpiece 16 can be abutted against the fixed clamping block 12 only under the action of the moving clamping block 7.

[0039] Exemplarily, the fixed clamping block 12 is a vertical plate mounted on the positioning seat 11. The left end of the workpiece 16 can be completely pressed on the fixed clamping block 12 to achieve stable clamping. And a abutting portion 13 is provided on the side of the clamping block close to the moving assembly. The abutting portion 13 is the part in contact with the workpiece 16. In this embodiment, the abutting portion 13 is the right end face of the fixed clamping block 12, and the moving assembly can be used to drive the component to closely abut against the abutting portion 13. In this embodiment, the fixed clamping block 12 is mounted on the positioning seat 11 through connecting pieces such as bolts or screws to achieve fixation.

[0040] It is worth noting that a plurality of first connecting pieces 14 are provided on the positioning seat 11 for connecting the positioning seat 11 and the bottom plate 1.

[0041] In an exemplary embodiment, the driving mechanism includes a fixed seat 2. A driving screw 3 is provided on the fixed seat 2. A mating hole 6 is formed on the side of the driving block 5 close to the fixed seat 2. The mating hole 6 is threadedly connected with the driving screw 3. The rotation of the driving screw 3 can be used to drive the driving block 5 to approach or move away from the fixed assembly.

[0042] In this embodiment, by providing the fixed seat 2, the driving screw 3 can be supported and positioned, and the driving screw 3 is rotatably connected to the fixed seat 2. When the driving screw 3 rotates, since the driving screw 3 and the driving block 5 are threadedly connected, the driving screw 3 can drive the driving block 5 to move along the axial direction of the driving block 5 to drive the moving assembly to move.

[0043] Exemplarily, the driving mechanism further includes a mounting plate 4. The mounting plate 4 is detachably connected to the bottom plate 1, and the fixed seat 2 is provided on the mounting plate 4. A plurality of second connecting pieces 15 are provided on the mounting plate 4 for connecting the mounting plate 4 and the bottom plate 1.

[0044] It is worth noting that in this embodiment, the driving screw 3 can be rotated manually, or the driving screw 3 can be rotated by an electric driving member such as a motor.

[0045] It should also be noted that in this embodiment, in addition to the above driving mechanism, components with telescopic functions such as hydraulic cylinders and hydraulic rods can also be used to drive the driving block 5 to move.

[0046] It should also be noted that in this embodiment, a positioning groove is formed at the front end of the fixed seat 2. The driving block 5 is slidably connected with the positioning groove. By providing the positioning groove, the driving block 5 can be limited and guided to achieve stable movement of the driving block 5.

[0047] In an exemplary embodiment, a positioning block 10 is detachably connected to the base. The positioning block 10 is located at the placement position, and the positioning block 10 is provided with a contact surface that contacts the component.

[0048] In this embodiment, the workpiece 16 can be preliminarily positioned by the provided positioning block 10. After the workpiece 16 is mounted on the positioning block 10, the workpiece 16 can move on the positioning block 10 under the action of the moving component until it abuts against the fixed clamping block 12.

[0049] Exemplarily, the positioning block 10 in this embodiment is integrally in the structure of a cuboid, and its width is smaller than the width of the workpiece 16 to avoid the downward protruding part of the special-shaped workpiece 16. The upper surface of the positioning block 10 has three positioning points, and the heights of the three positioning points are higher than other places, so as to reduce the contact area between the positioning block 10 and the workpiece 16, reduce the frictional resistance when the workpiece 16 moves, and facilitate the movement of the workpiece 16 on the positioning block 10.

[0050] In summary, through the provided clamping mechanism and driving mechanism, under the action of the driving mechanism, the workpiece 16 can drive the moving component in the clamping mechanism to move to the fixed clamping block 12 for clamping, effectively reducing and eliminating the vibration generated by the workpiece 16 during high-speed rotation, and further eliminating and reducing problems such as unstable product quality and abnormal damage of the tool caused by vibration.

[0051] The above embodiments only illustrate the principles and effects of the present invention by way of example, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
