[0033] refer to Figures 1 to 8An embodiment of the utility model provides a universal pop-up dial, including: a dial body 1, a dial pin 4, an elastic member 3, a first blocking member 2 and a second blocking member 71.

[0034] The dial body 1 has a first working surface 1a and a second working surface 1b opposite to each other. The first working surface 1a is used to face the tailstock of the grinding machine, and the second working surface 1b is used to face the end surface of the axle to be processed.

[0035] When in use, the tailstock (not shown) of the grinder is fixedly connected to the dial body 1 and drives the dial body 1 to rotate, and then the pin 4 on the dial body 1 drives the axle to be processed (not shown) to rotate.

[0036] Combination Figure 1 , Figure 2 and Figure 5 Two oblong holes 7 are provided on the second working surface 1b. The oblong holes 7 are step-type through holes. The oblong holes 7 form a second opening 7b on the second working surface 1b. The other side opening of the oblong hole 7 is its first opening 7a. The orthographic projection of the first opening 7a on the plane where the dial body 1 is located surrounds the orthographic projection of the second opening 7b on the plane where the dial body 1 is located. The orthographic projection of the first opening 7a on the plane where the dial body 1 is located does not overlap with the orthographic projection of the second opening 7b on the plane where the dial body 1 is located.

[0037] Combination Figure 2 and Figure 7 The detent pin 4 has a sheet-like base 41 and a column 42 fixed on the base 41. The column 42 is perpendicular to the base 41. The detent pin 4 is located in the oblong hole 7. In a natural state, the base 41 of the detent pin 4 contacts the step plane of the oblong hole 7. The column 42 of the detent pin 4 passes through the dial body 1 from the second opening 7b of the oblong hole 7. The oblong hole 7 limits the detent pin 4 to move along the length direction of the oblong hole 7 and along the opening direction of the oblong hole 7.

[0038] The base 41 only needs to extend beyond the column 42 in the radial direction of the column 42. The sheet-shaped base 41 can reduce the dimension of the detent pin 4 in the axial direction thereof.

[0039] refer to Figure 2 , the elastic member 3 is located in the oblong hole 7. The elastic member 3 is, for example, a spring or a bent spring sheet.

[0040] Combination Figure 2 and Figure 6 The second blocking member 71 is fixed at the first opening 7a of the oblong hole 7 to block the first opening 7a of the oblong hole 7, and a third assembly through hole 711 is provided on the second blocking member 71 to allow the elastic member 3 and the push pin 4 to withdraw from the oblong hole 7 from the third assembly through hole 711.

[0041] Note: The second blocking member 71 is relatively thin. Figure 2The second blocking member 71 is omitted.

[0042] Combination Figure 2 , Figure 3 , Figure 4 and Figure 6 The first blocking member 2 blocks the third assembly through hole 711 in a detachable manner, and the oblong hole 7, the second blocking member 71 and the first blocking member 2 cooperate to form an oblong groove.

[0043] One end of the elastic member 3 is fixedly connected to the base 41 of the detent pin 4 (for example, by welding), and the other end is against the bottom of the oblong groove. The elastic member 3 and the detent pin 4 can move along the length direction of the oblong hole 7 as a whole.

[0044] The assembly process of the universal pop-up dial is as follows: fix the second blocking member 71 at the first opening 7a of the oblong hole 7 to block the first opening 7a. Insert the elastic member 3 and the detent pin 4 into the oblong hole 7 from the third assembly through hole 711 on the second blocking member 71, and the portion of the base 41 of the detent pin 4 that protrudes beyond the column 42 abuts against the stepped surface of the oblong hole 7. Then insert (for example, screw in) the first blocking member 2 into the third assembly through hole 711 to block the third assembly through hole 711. The assembly process is simple.

[0045] The maintenance process of the universal pop-up dial is as follows: remove the first blocking member 2 from the third assembly through hole 711, remove the elastic member 3 and the pull pin 4 from the third assembly through hole 711, and then replace the new elastic member 3 and the pull pin 4. The maintenance process is simple.

[0046] The process of using the universal pop-up dial is as follows: the elastic member 3 and the pin 4 are moved along the length direction of the oblong hole 7 to a suitable position so that the free end of the column 42 of the pin 4 is inserted into the driving groove on the end surface of the axle to be processed. The bottom of the driving groove abuts against the column 42 of the pin 4.

[0047] Since the detent pin 4 can move freely along the length direction of the oblong hole 7, the universal pop-up dial can be applied to axles with different drive slot positions. Since the detent pin 4 is replaceable, the shape and size of the column 42 of the detent pin 4 can be freely customized, and the universal pop-up dial can adapt to drive slots of different shapes and sizes.

[0048] Optionally, refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 The first blocking member 2 is an externally threaded countersunk nut, and a processing groove 21 is provided on the surface of the first blocking member 2 facing away from the second opening 7b of the oblong hole 7. The processing groove 21 is used to detachably fix the first blocking member 2 in the third assembly through hole 711 and avoid structural interference.

[0049] refer to Figure 4The processing groove 21 is a rectangular groove. For example, a flat-blade screwdriver can be inserted into the processing groove 21 to screw the externally threaded countersunk nut into the third assembly through hole 711.

[0050] The processing groove 21 can be, for example, a cross-shaped groove.

[0051] Optionally, the second blocking member 71 is a metal plate. For example, the second blocking member 71 is welded to the second opening 7b of the oblong hole 7. The second blocking member 71 is fixed by welding to reduce structural interference.

[0052] Optionally, the cylinder 42 of the detent pin 4 is a cylindrical body 42 with a chamfered free end, which matches the shape of the driving groove on the end face of the axle to be processed and facilitates the free end of the cylinder 42 of the detent pin 4 to be inserted into the driving groove.

[0053] Optionally, the base 41 of the detent pin 4 is disc-shaped.

[0054] Optionally, the elastic member 3 is a spring, and when the base 41 of the detent 4 contacts the stepped plane of the oblong hole 7, the spring is in a free state or in a compressed state.

[0055] Optionally, refer to Figure 1 and Figure 8 A first assembly through hole 6 is opened in the middle of the first working surface 1a of the dial body 1. The first assembly through hole 6 is a stepped circular through hole. The opening size formed by the first assembly through hole 6 on the first working surface 1a of the dial body 1 is larger than the opening size formed by the first assembly through hole 6 on the second working surface 1b of the dial body 1.

[0056] When in use, the tailstock of the grinding machine passes through the first assembly through hole 6 and exceeds the second working surface 7 b of the dial body 1 .

[0057] Optionally, refer to Figure 1 and Figure 2 When the first blocking member 2 and the second blocking member 71 are withdrawn, the oblong hole 7 is connected to the first assembly through hole 6. This design is to make the overall structure compact.

[0058] Optionally, refer to Figure 1 and Figure 8 The dial body 1 includes a circular bottom area 11 and a circular boss 12 disposed on the circular bottom area 11, and a plurality of second assembly through holes 5 are provided in the area where the circular bottom area 11 exceeds the circular boss 12. The second assembly through holes 5 are also used for assembly between the dial body 1 and the tailstock of the grinding machine.

[0059] In the embodiments of the present invention, reference is made to Figure 1 Two oblong holes 7 are arranged on the dial body 1 , the length direction of the two oblong holes 7 is the radial direction of the dial body 1 , and the included angle between the length directions of the two oblong holes 7 is 120°.

[0060] There may be errors in the size and position of the three drive grooves on the end face of the axle to be processed, but the probability that two drive grooves can match the pins 4 in the two oblong holes 7 is greater. In addition, the pins 4 are movable and replaceable. These two factors combined further improve the adaptability of the universal pop-up dial.

[0061] In other embodiments, the number of the oblong holes 7 may also be 3, and the included angle between any two oblong holes 7 in the length direction is 120°. Figure 1 The embodiment shown.
