Since the workpiece is long, it is difficult to center it, and the jaws are easily dropped when moving, damaging the workpiece. The alignment time is very long, the labor intensity of workers is high, the processing efficiency is low, the quality is poor, the paint surface of the workpiece is easily scratched, and the operator is required to have high operating skills.

[0029] The present invention will be further described with reference to the following embodiments.
[0030] Example 1.
[0031] like Figure 1-4 As shown, a quick clamping device for a time delayer includes a positioning packing 1, which is fixedly mounted on the main shaft of a lathe. A two-jaw centering chuck 2 is fixedly mounted on the positioning packing 1, and two movable clamping jaws 3 are slidably mounted on the two-jaw centering chuck. An arc-shaped clamping block 4 is fixedly mounted on the opposite side of the two movable clamping jaws 3, and each arc-shaped clamping block 4 is symmetrical with the clamping activity center line F of the movable clamping jaw 3. A centering shaft clamping block 5 is installed in the center of the two-jaw centering chuck 2 by interference fit.
[0032] The present application is used for processing the inner hole of the timer 9. First, it is fixedly installed on the lathe spindle through the positioning packing 1 and rotates with the lathe spindle. At the same time, the positioning packing 1 is also fixedly installed with a two-jaw centering chuck 2. The two-jaw centering chuck 2 is symmetrically moved and clamped about the center point of the chuck. This technology is a common chuck in the prior art and is not described in detail in this application. The present application installs an arc-shaped clamping block 4 on the movable clamping jaw 3 to clamp the timer 9. Since the four sides of the timer 9 are the same and have edges, the two arc-shaped clamping blocks 4 are in contact with the edges of the timer 9 to clamp them, so as to fix the rotation axis of the timer 9. At the same time, the centering shaft clamping block 5 can be used to axially limit the timer 9 with through holes 10 of different diameters, and further limit the rotation axis of the timer 9.
[0033] The centering shaft clamp 5 includes a fixed part 6, a positioning hole 7 is provided in the center of the two-jaw centering chuck 2, the fixed part 6 and the positioning hole 7 are installed with interference fit, and a guide slope 8 is provided on the side of the centering shaft clamp 5 away from the fixed part 6. A delay device 9 is movably clamped between the two movable clamping jaws 3, and a through hole 10 is provided on the delay device 9, which is engaged with the guide slope 8.
[0034] The centering shaft clamping block 5 is concentrically fixed to the center of the two-jaw centering chuck 2 through the fixing portion 6, and is clamped with the through hole 10 of the delay device 9 through the guide slope 8. The guide slope 8 can facilitate the rapid clamping of the through hole 10.
[0035] The horizontal length of the inner arc of the arc-shaped clamping block 4 is D1, the side width of the delay device 9 is D2, and D1 and D2 satisfy D1>D2.
[0036] The arc-shaped clamping block 4 needs to ensure that the side surfaces of the delay device 9 are covered and clamped.
[0037] The outer diameter of the guide slope 8 is R1, the inner diameter of the guide slope 8 is R3, the outer diameter of the through hole 10 is R2, and R1, R2, and R3 satisfy R1>R2>R3.
[0038] The guide slope 8 allows the through hole 10 to be quickly snapped onto the slope.
[0039] The rotation axis of the lathe spindle and the rotation axis of the through hole 10 are on the same straight line.
[0040] The vehicle-mounted rotating shaft drives the time delay device 9 to rotate concentrically.
[0041] The utility model drives the arc-shaped clamping block 4 to engage with the side wall edge of the delay device 9 through two movable clamping claws 3, and then engages with the guide slope 8 on the centering shaft clamping block 5 through the through hole 10, so that the delay device 9 can be quickly aligned and its axial and radial directions can be limited. The lathe shaft is then used to drive the delay device 9 to rotate and process the inner hole. The alignment time of the delay device 9 is short, the alignment accuracy is higher, and the clamping degree of the delay device 9 is higher.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
