[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The present embodiment provides a technical solution: a boring jig for automobile parts, comprising a fixed base plate 1, a support column 7 is arranged at the center of the fixed base plate 1, a positioning shaft 8 is arranged at the upper end of the support column 7, an electric push rod 9 is arranged on the inner side of the support column 7, a screw rod 3 is arranged on the upper side of the fixed base plate 1, a sliding seat 4 is passed through the screw rod 3, a limiting clamping rod 12 is arranged on one side of the upper part of the sliding seat 4, a cylinder 5 is arranged on the inner side of the upper part of the sliding seat 4, a lower pressure plate 6 is arranged on the upper end of the cylinder 5, a turntable 10 is arranged at one end of the screw rod 3, and a rotating handle 11 is arranged on the side of the turntable 10 away from the screw rod 3.

[0019] like Figure 1-3 As shown, the turntable 10 can be driven to rotate by rotating the handle 11, thereby rotating the screw 3, causing the sliding seat 4 to move horizontally, and then adjusting the distance between the sliding seat 4 and the support column 7, so that the device can adapt to disc structures of different sizes, so that the limit clamping rod 12 at the upper end of the sliding seat 4 can clamp and fix the outer ring side of the disc structure. At the same time, the cylinder 5 drives the lower pressure plate 6 to press down and fix the disc structure, ensuring that the parts that need boring processing are effectively fixed.

[0020] Clamping grooves 2 are arranged on both sides of the fixed base plate 1. The fixed base plate 1 is slidably connected to the support column 7. The support column 7 is connected to the upper end of the electric push rod 9 by bolts.

[0021] like Figure 1-3 As shown, the electric push rod 9 can adjust the height of the support column 7 so that the support column 7 can support disc workpieces of different thicknesses. The positioning shaft 8 can be installed in a corresponding size according to the size of the circular hole of the workpiece, thereby positioning the center of the disc workpiece, or it can be disassembled and not used.

[0022] The sliding seat 4 is connected to the fixed base plate 1 through a screw rod 3, and the screw rod 3 is connected to the rotating disk 10 through bolts.

[0023] like Figure 1-3 As shown, the rotation of the screw rod 3 can provide power for the movement of the sliding seat 4, so that the sliding seat 4 moves toward the support column 7 or away from the support column 7.

[0024] The sliding seat 4 is connected to the cylinder 5 by screws, and the upper end of the cylinder 5 is connected to the lower pressing plate 6 by bolts.

[0025] like Figure 1-3 As shown, the cylinder 5 provides power for the movement of the lower pressing plate 6, so that the lower pressing plate 6 can stably press the workpiece to ensure the stability of the workpiece during processing.

[0026] The positioning shaft 8 is connected to the support column 7 through threads, and the lower end of the electric push rod 9 is connected to the fixed base plate 1 through bolts.

[0027] The rotating handle 11 is connected to the rotating disk 10 via bolts.

[0028] The working principle of the automobile parts boring fixture provided by the utility model is as follows: Figure 1-Figure 3 As shown, when in use, the clamping grooves 2 on both sides of the fixed base plate 1 are clamped and fixed by the T-bolts on the boring lathe. According to the diameter of the workpiece, the turntable 10 is adjusted to rotate by rotating the handle 11, so that the screw rod 3 rotates, and then the sliding seat 4 moves in the horizontal direction, and the spacing between the sliding seats 4 is adjusted, so that it can adapt to workpieces of different diameters. The outer ring side of the disc workpiece is clamped and fixed by the limit clamping rod 12 on the movable sliding seat 4. At the same time, the cylinder 5 drives the lower pressure plate 6 to move downward, so that the lower pressure plate 6 is pressed and fixed to the position of the disc workpiece that does not need boring, so that the workpiece fixing effect is guaranteed, and then the accuracy of workpiece processing is guaranteed. Such a jig can adapt to disc workpieces of different sizes, thereby improving the utilization rate of the jig.

[0029] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
