[0025] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0026] like Figure 1 As shown, a sealing assembly tool comprises:

[0027] A base 1 and an assembly platform 11 arranged on the base 1;

[0028] like Figure 2 As shown, the implementation includes: an adjustment column seat 3, which is arranged on the assembly platform 11, a slide groove 34 is arranged in the port of the adjustment column seat 3, an auxiliary assembly sleeve 33 is arranged in the slide groove 34, and the outer wall surface of the auxiliary assembly sleeve 33 is an inclined plane in a conical shape, and the outer diameter decreases uniformly from top to bottom. During installation, the staff will put the sealing member to be assembled on the outer wall surface of the auxiliary assembly sleeve 33 to allow the sealing member to be evenly expanded;

[0029] In this embodiment, specifically, a mounting rod 31 is connected to one side of the surface of the base 1, and the side of the adjusting column seat 3 is connected to the mounting rod 31. A lifting cylinder 32 is vertically connected to the adjusting column seat 3. The rod body of the lifting cylinder 32 passes through the adjusting column seat 3 and is connected to the top surface of the auxiliary assembly sleeve 33, so as to drive the automatic lifting and lowering adjustment of the auxiliary assembly sleeve 33. By sleeve the sealing member to be assembled on the outer wall surface of the auxiliary assembly sleeve 33, the sealing member is evenly expanded, and then the lifting cylinder 32 is started to drive the auxiliary assembly sleeve 33 to lower its height, so that the bottom port of the auxiliary assembly sleeve 33 is sleeved on the piston and located above the sealing groove of the piston, so that the expanded sealing member is pushed downward to be stuck in the sealing groove, so that convenient assembly can be achieved;

[0030] like Figure 2 and Figure 3As shown, the implementation also includes: a double-ended screw 2, which is rotatably arranged on the assembly table 11, and sliding seats 24 are sleeved on both sides of the double-ended screw 2, and a clamping block 21 and a clamping block 23 are connected to the two sliding seats 24, and clamping notches 22 are arranged in the ports of the clamping block 21 and the clamping block 23, and the inner wall of each clamping notch 22 is connected to a rubber protective pad, which can provide buffer protection for the outer wall surface of the piston;

[0031] Among them, the assembly table 11 is provided with a mounting groove 111, the double-headed screw 2 is rotatably arranged in the mounting groove 111, and two sliding seats 24 are respectively threadedly sleeved on two opposite sections of the thread teeth of the double-headed screw 2, and an auxiliary slide bar 112 is arranged in the mounting groove 111. Each sliding seat 24 is movably sleeved on the auxiliary slide bar 112. The double-headed screw 2 is driven by a servo motor externally arranged on the side of the assembly table 11. The servo motor drives the double-headed screw 2 to rotate, driving a pair of sliding seats 24, so that the clamping block 1 21 and the clamping block 2 23 are close to each other, so that the clamping notch 22 can automatically clamp and fix pistons of different batches;

[0032] In this embodiment, limiting rods 211 are further provided on the side of clamp block 1 21 at both ends of the clamping notch 22, and clamp block 23 is provided with slots 231 at positions corresponding to each limiting rod 211, and each limiting rod 211 is movably inserted in the slot 231, so as to improve the stability of clamp block 1 21 and clamp block 2 23 during clamping.

[0033] like Figures 1 to 3 As shown, in this embodiment, it should also be noted that the actual size of each component in the application document is selected and installed before implementation according to the actual needs on site. The lifting cylinder 32 and servo motor mentioned in the document are both commercially available products of the prior art, and the working principle has been made public. The corresponding product model is selected for installation before implementation. In addition, it should be noted that this application document only targets the existing assembly of seals (O-rings). Most of them are assembled manually into the seal groove on the piston. This method is time-consuming and labor-intensive, with low assembly efficiency and the disadvantage of easily damaging the seal due to excessive pulling force. It does not involve other aspects; the working principle of the assembly tooling of this kind of seal is introduced as follows:

[0034] During installation and use, the staff places the piston to be assembled on the assembly table 11, so that the double-headed screw 2 is driven by the servo motor to rotate, driving a pair of sliding seats 24, so that the clamping block 1 21 and the clamping block 2 23 are brought close together, so that the clamping notch 22 can automatically clamp and fix pistons of different batches;

[0035] After the piston is fixed, the seal to be assembled is sleeved on the outer wall of the auxiliary assembly sleeve 33 to expand the seal evenly, and then the lifting cylinder 32 is started to drive the auxiliary assembly sleeve 33 to be lowered, so that the bottom port of the auxiliary assembly sleeve 33 is sleeved on the piston and located above the sealing groove of the piston. In this way, the expanded seal is pushed downward and stuck in the sealing groove, which can achieve convenient assembly and save time and effort. The seal is evenly expanded, which can effectively avoid damage to the seal due to excessive pulling force, and has higher assembly efficiency and a wider range of adaptability.

[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
