[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] As Figure 1 shown, the mechanism is used for the high-pressure sealing detection of the product 10. The mechanism includes a stop block 1, a support base 2, a T-shaped floating block 3 and an elastic adjustment assembly. The stop block 1 is installed on the support base 2, and the product 10 is installed on the stop block 1. The stop block 1 is installed on the upper part of the support base 2 through the T-shaped floating block 3 with clearance fit and can float up and down. An elastic adjustment assembly is arranged below the stop block 1. An ear is arranged in the middle of the support base 2, and the elastic adjustment assembly is elastically installed on the ear in the middle of the support base 2, and the upper end of the elastic adjustment assembly is in contact connection with the bottom surface of the stop block 1.

[0025] The stop block 1 is used to be embedded into the product opening 12 of the product 10, so that the top surface of the stop block 1 is connected to the piston 11 of the product 10, thereby restricting the up and down freedom of the piston 11.

[0026] In specific implementation, as Figure 1 shown, the product 10 adopts a brake caliper, and a matching concave structure for the elastic adjustment assembly to pass through is arranged on the outer side of the brake caliper.

[0027] As Figure 1 and Figure 2 shown, there are two elastic adjustment assemblies. The two elastic adjustment assemblies are arranged in parallel at intervals. The upper ends of the two elastic adjustment assemblies are both in contact connection with the bottom surface of the stop block 1, and the lower ends are elastically connected to the ears of the support base 2.

[0028] The elastic adjustment assembly includes a T-shaped support block 5, a compression spring 6, a limit bolt 7, an upper locking nut 8 and a lower locking nut 9. A threaded through hole is opened on the ear of the support base 2. The lower end of the limit bolt 7 passes through the threaded through hole on the ear of the support base 2. Upper locking nuts 8 and lower locking nuts 9 are both sleeved on the limit bolt 7 outside the upper and lower sides of the threaded through hole through threads. The upper end of the limit bolt 7 is fixedly sleeved with a T-shaped support block 5 and is used for contact connection with the bottom surface of the stop block 1. A compression spring 6 is sleeved on the limit bolt 7 between the T-shaped support block 5 and the upper locking nut 8. The upper and lower ends of the compression spring 6 are respectively connected to the T-shaped support block 5 and the upper locking nut 8. The initial spring force of the compression spring 6 in the natural state is equal to the self-weight of the stop block 1.

[0029] The upper end of the limit bolt 7 is provided with a flange. An annular groove is formed in the upper end of the inner wall of the central hole of the T-shaped support block 5. The flange is fitted into the annular groove, so that the upper end of the limit bolt 7 and the central hole of the T-shaped support block 5 are fitted together, and the top surfaces of the T-shaped support block 5 and the limit bolt 7 are flush. And it is required that the depth of the annular groove of the T-shaped support block 5 is greater than the thickness of the flange of the limit bolt 7, and the dimensional difference between the depth of the annular groove of the T-shaped support block 5 and the thickness of the flange of the limit bolt 7 is greater than the up-and-down floating clearance dimension between the T-shaped floating block 3 and the support seat 2.

[0030] The lower part of the support seat 2 is connected to the equipment translation cylinder, and the equipment translation cylinder is used to drive the whole mechanism to move.

[0031] Such as Figure 3 As shown, it further includes an inner hexagon bolt 4. The T-shaped floating block 3 is installed in the horizontal hole formed in the upper part of the support seat 2 with a clearance fit, and the T-shaped floating block 3 is fixed to the side of the stop block 1 by the inner hexagon bolt 4.

[0032] After the inner hexagon bolt 4 passes through the central hole of the T-shaped floating block 3, it is screwed into the threaded hole provided on the side of the stop block 1, so as to fix the T-shaped floating block 3 and the stop block 1 together by the inner hexagon bolt 4.

[0033] The outer circle of the T-shaped floating block 3 and the circular through hole of the support seat 2 are in clearance fit, and there is a certain designed clearance amount to ensure that the stop block 1 can move up and down a certain distance. The clearance amount is a set value to ensure that the stop block 1 can elastically move up and down a certain amount to ensure that the stop block 1 effectively engages with the product opening 12.

[0034] The T-shaped floating block 3 has an outer end extending out of the support seat 2. An outer flange is provided at the outer end, and the diameter of the outer flange is greater than the diameter of the horizontal hole of the support seat 2, which is used to limit the displacement of the stop block 1 along the axial direction of the T-shaped floating block 3.

[0035] In a specific implementation, the stop block 1 is a cuboid. The upper end surface is used to support the piston 11 of the product 10, and a threaded hole is provided on the back surface. At the same time, the back surface is in contact with the support seat 2. The upper end of the support seat 2 is provided with a circular through hole as a horizontal hole for installing the T-shaped floating block 3. The inner hexagon bolt 4 is screwed into the threaded hole on the back surface of the stop block 1 through the inner hole of the T-shaped floating block 5 to realize the connection between the stop block 1 and the support seat 2.

[0036] The up-and-down clearance amount between the depth of the annular groove of the T-shaped support block 5 and the thickness of the flange of the limit bolt 7 is greater than the clearance amount between the circular through hole of the support seat 2 and the outer diameter of the T-shaped floating block 3, ensuring that the T-shaped support block 5 only bears the self-weight of the stop block.

[0037] There are two lugs protruding from the middle of the support base 2. The two lugs are symmetrically arranged on both sides, and a vertical threaded through hole is provided at the center position of each lug. The threaded through hole is used to install the limit bolt 7. Locking nuts 8 and 9 are respectively provided at the upper and lower end faces of the lug for the limit bolt 7. The two locking nuts can fasten the limit bolt 7 on the lug. According to the height of the product 13, adjust the up and down positions of the limit bolt 7 to determine the initial position of the stop block 1, and then tighten the upper and lower locking nuts 8 and 9.

[0038] The upper end of the limit bolt 7 is matched with the T-shaped support block 5, and the T-shaped support block 5 is sleeved on the limit bolt 7. The T-shaped support block 5 is in contact with the lower plane of the stop block 1 and is used to support the stop block 1 in the free state. The T-shaped support block 5 is a plastic part and is in contact with the lower end face of the stop block 1 to bear the weight in the free state.

[0039] A compression spring 6 is provided between the T-shaped support block 5 and the upper locking nut 8 along the axial direction. The compression spring 6 is used to support the T-shaped support block 5. The upper end of the compression spring 6 is in contact with the T-shaped support block 5, and the lower end is in contact with the upper locking nut 8. The initial spring force of the compression spring 6 is equal to the self-weight of the stop block 1.

[0040] The support base 2 mainly serves to support the stop block 1. The lower end of the support base 2 is connected to the equipment translation cylinder. The equipment translation cylinder drives the support base 2 and then drives the stop block 1 to translate to the product opening 12 to limit the displacement of the piston 11.

[0041] The existing press-fitting piston tooling is as Figure 2 shown, including a stop block 1, a support base 2, and an internal hexagonal bolt 4. The difference is that the present utility model adjusts the connection mechanism between the stop block and the support base on the basis of the existing technology. The connection structure includes a T-shaped floating block 3, an internal hexagonal bolt 4, a T-shaped support block 5, a compression spring 6, a limit bolt 7, an upper locking nut 8, and a lower locking nut 9. The stop block 1 can effectively and accurately enter the product opening 12, and at the same time, the up and down initial positions of the stop block 1 can be adjusted.

[0042] The specific implementation process of the present utility model is as Figure 3 shown:

[0043] In the elastic adjustment component, after loosening the upper locking nut 8 and the lower locking nut 9, adjust the position of the limit bolt 7 screwed into the threaded through hole of the lug of the support base 2 to adjust the height of the limit bolt 7; after adjusting the height, tighten the upper locking nut 8 and the lower locking nut 9 so that the position of the limit bolt 7 relative to the lug of the support base 2 is fixed.

[0044] At the beginning of the assembly process, fix the product 10 on the stop block 1 so that the piston 11 is in contact with the upper surface of the stop block 1.

[0045] At this time, blow air into the oil inlet hole 13 of the product for high-pressure sealing detection. The stopper 1 enters the opening 12 of the product 10 to limit the up and down freedom of the piston 11. After blowing air to inflate and maintaining the pressure for a certain time, the on-line detection is completed.

[0046] The floating stopper 1 can effectively enter the opening 12 of the product, avoiding jamming due to differences in the initial positions of the pistons 11. At the same time, the up and down height can be adjusted to suit multiple specifications of products, with strong versatility.

[0047] Therefore, the utility model effectively improves the one-time passing rate of high-pressure sealing detection, reduces the types of tooling, reduces the product changeover time, improves production efficiency, and reduces production costs.
