Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a multi-piece clamping and positioning device for half-shaft gears. Background Art

[0002] When processing the half-shaft of a gear, sometimes it is necessary to drill holes in the large-end face of such a half-shaft. The traditional processing method uses a three-jaw chuck for clamping, but the workpiece is too long to ensure the clamping accuracy, and only one product can be processed at a time, which is not conducive to improving work efficiency. Summary of the Invention

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a multi-piece clamping and positioning device for half-shaft gears, which includes a base. The base is fixedly connected to a table board through a column. A chute is arranged on the table board. Through holes are evenly and symmetrically arranged on both sides of the chute. Inner cylinders are arranged in the through holes. A notch is arranged at the connection between the through hole and the chute. Elastic pieces are arranged on the inner cylinders corresponding to the notches. Oblique sliders are arranged in the chute corresponding to the notches. Sliders and oblique sliders are alternately placed at intervals in the chute. The oblique sliders include upper sliders and lower sliders with the same structure. The cross-sections of the upper sliders and the lower sliders are right-angled triangles. The hypotenuses of the upper sliders and the lower sliders are connected. An adjusting bolt is arranged at one end of the chute. A cover plate is arranged on the surface of the chute. The inner cylinders are fixed in the through holes through positioning bolts.

[0004] The sum of the lengths of the sliders and the oblique sliders is less than the length of the chute, and the width of the oblique sliders is less than the width of the chute.

[0005] Positioning bolts connecting the through holes and the inner cylinders are arranged on the table board, and holes for the positioning bolts to pass through are arranged in the inner cylinders.

[0006] Compared with the prior art, the beneficial effects of the utility model are as follows: The utility model can clamp multiple workpieces at one time, which is convenient for clamping and is conducive to improving production efficiency. Moreover, through the cooperation of the oblique sliders and the elastic pieces, it is conducive to locking the workpieces and ensuring the processing accuracy. Brief Description of the Drawings

[0007] Figure 1 is a structural schematic diagram of the utility model.

[0008] Figure 2 is Figure 1 the cross-sectional structural schematic diagram of

[0009] In the figure: adjusting bolt 1, table board 3, inner cylinder 4, positioning bolt 5, upper slider 6, lower slider 7, slider 8, elastic piece 9, base 10, column 11. Detailed Description of the Embodiment

[0010] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0011] In Figure 1 and Figure 2 a multi-piece clamping and positioning device for a half-shaft type gear, which includes a base 10. The base 10 is fixedly connected to a platen 3 through a column 11. A chute is provided on the platen 3. Through holes are evenly and symmetrically arranged on both sides of the chute. Inner cylinders 4 are arranged in the through holes. A notch is provided at the connection between the through hole and the chute. Elastic pieces 9 are arranged on the inner cylinders 4 corresponding to the notches. Oblique sliders are arranged in the chute corresponding to the notches. Sliders 8 and oblique sliders are alternately placed at intervals in the chute. The oblique sliders include an upper slider 6 and a lower slider 7 with the same structure. The cross sections of the upper slider 6 and the lower slider 7 are right-angled triangles. The hypotenuses of the upper slider 6 and the lower slider 7 are joined. An adjusting bolt 1 is arranged at one end of the chute. A cover plate is arranged on the surface of the chute. The inner cylinders 4 are fixed in the through holes through positioning bolts 5.

[0012] Further, the sum of the lengths of the sliders 8 and the oblique sliders is less than the length of the chute, and the width of the oblique sliders is less than the width of the chute.

[0013] Further, positioning bolts 5 connecting the through holes and the inner cylinders 4 are arranged on the platen 3, and holes for the positioning bolts 5 to pass through are arranged in the inner cylinders 4.

[0014] When processing a workpiece, the workpiece is placed into the inner cylinder 4. The adjusting bolt 1 is tightened. The slider 8 pushes the oblique slider to move to the right. Since the oblique slider includes an upper slider 6 and a lower slider 7 with the same structure, and the width of the oblique slider is less than the width of the chute, at this time, the upper slider 6 and the lower slider 7 will move towards the inner cylinders 4 on both sides respectively and squeeze the elastic pieces 9. The elastic pieces 9 will lock the workpiece to prevent it from shifting during processing. At the same time, the positioning bolts 5 can also pass through the empty cylinders of the inner cylinders 4 to further lock and position the workpiece. Then it is fixed on a machine tool through the base 10 for processing.

[0015] After processing is completed, the positioning bolts 5 are loosened, and at the same time, the adjusting bolt 1 is loosened. At this time, the elastic pieces 9 rebound, and the upper slider 6 and the lower slider 7 return to their original positions, facilitating the removal of the processed workpiece.

[0016] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
