The described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 3 A seat ring press height detection jig comprises a frame 1, a second clamping block 5 is fixed to the upper surface of the frame 1 by bolts, two screw rods 8 are welded to one side of the second clamping block 5, and a first clamping block 2 is slidably connected to the outer sides of the two screw rods 8, and an engine cylinder head with a press-fitted seat ring is placed between the first clamping block 2 and the second clamping block 5, and then the first clamping block 2 is pushed to move along the screw rod 8, so that the first clamping block 2 and the second clamping block 5 clamp and fix the engine cylinder head;

[0023] The outer sides of the two screw rods 8 are provided with locking components for fixing the first clamping block 2. The tops of the first clamping block 2 and the second clamping block 5 are provided with dovetail grooves 6. The first slider 3 and the second slider 4 are slidably connected in the two dovetail grooves 6 respectively. Two guide rods 16 are welded on one side of the second slider 4. The two guide rods 16 pass through the first slider 3. The outer sides of the two guide rods 16 are slidably connected with a third slider 19. The top of the third slider 19 is located between the two guide rods 16. A through hole 20 is provided. A through hole 20 is slidably connected to the seat. The third slider 19 is provided with a locking assembly for fixing the scale rod 9. The third slider 19 is moved along the guide rod 16, and the scale rod 9 on the third slider 19 is moved to just above the seat ring. Then the locking assembly no longer fixes the scale rod 9. At this time, under the action of gravity, the scale rod 9 is moved downward and inserted into the seat ring, so that the scale rod 9 is inserted to the bottom, so that the height of the seat ring can be measured by the scale rod 9, which is convenient for measuring the height of the seat ring press-fitting, thereby improving the convenience of the seat ring press-fitting detection.

[0024] In the utility model, the locking components are two flange nuts 7, which are respectively threadedly connected to the outer sides of the two screw rods 8, and the two flange nuts 7 are both located on the side of the first clamping block 2 away from the second clamping block 5. After the first clamping block 2 and the second clamping block 5 clamp and fix the engine cylinder head with the seat ring pressed, the first clamping block 2 is locked and fixed by the flange nuts 7, thereby preventing the first clamping block 2 from moving;

[0025] The locking assembly includes a avoidance groove 14, which is provided in the third slider 19. The avoidance groove 14 is connected to the through hole 20. An arc block 15 is slidably connected in the avoidance groove 14. A pull rod 17 is welded on one side of the arc block 15, and the pull rod 17 extends out of the third slider 19. The circumferential outer wall of the pull rod 17 is sleeved with a spring 18 at a position located in the avoidance groove 14, and the two ends of the spring 18 are respectively fixed to the arc block 15 and the third slider 19. Then, the pull rod 17 is pulled to move, and the pull rod 17 will drive the arc block 15 to move and squeeze the spring 18, so that the scale rod 9 is no longer fixed. When the scale rod 9 falls to the bottom, the pull rod 17 is released. At this time, the arc block 15 will be reset under the action of the spring 18, so that the arc block 15 squeezes and fixes the scale rod 9 under the action of the spring 18, which can prevent the scale rod 9 from moving.

[0026] A sleeve 12 is sleeved on the outer side of the scale rod 9, and an observation groove for observing the scale is provided on one side of the sleeve 12. Two symmetrically distributed stop rods 10 are welded on the outer side of the sleeve 12 to limit the movement of the sleeve 12. Vertically distributed grooves 13 are provided on both sides of the scale rod 9 to allow the sleeve 12 to move vertically along the groove direction of the groove 13. When the scale rod 9 falls to the bottom, the stop rod 10 will contact the engine cylinder head. At this time, the scale rod 9 falls and the stop rod 10 will prevent the sleeve 12 from falling. At this time, the scale on the scale rod 9 can be observed through the observation groove on the sleeve 12, so that the staff can observe the scale conveniently. The third slider 19 is located between the first slider 3 and the second slider 4.

[0027] Working principle: when it is needed, the engine cylinder head with the seat ring pressed is placed between the first clamping block 2 and the second clamping block 5, and then the first clamping block 2 is pushed to move along the screw rod 8, so that the first clamping block 2 and the second clamping block 5 clamp and fix the engine cylinder head, and then the first clamping block 2 is locked and fixed by the flange nut 7, and the first clamping block 2 will drive the first slider 3 to move along the guide rod 16 during the movement, and then the third slider 19 can be moved along the guide rod 16, and the scale rod 9 on the third slider 19 is moved to the top of the seat ring, and then the pull rod 17 is pulled to move, and the pull rod 17 will drive the arc block 15 to move and squeeze the spring 18. At this time, under the action of gravity, the scale rod 9 will move downward and be inserted into the seat ring, so that the scale rod 9 is inserted to the bottom, so that the height of the seat ring is measured by the scale rod 9, which is convenient for measuring the height of the seat ring press-fitting, and improves the convenience of the seat ring press-fitting detection.
