DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described below in combination with specific implementation methods. The drawings are only used for exemplary descriptions, and only show schematic diagrams rather than physical drawings, and cannot be understood as limitations of this patent; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0015] The utility model of the unloading valve joint and outer ring assembly tooling includes a manual crimping machine 1 and an assembly mold. The assembly mold is arranged on the workbench of the manual crimping machine 1. The assembly mold includes a base 2 and an assembly seat 3. The assembly seat 3 is detachably arranged on the top of the base 2. A cross plate 4 is arranged at the lower end of the slide rod of the manual crimping machine 1. Two punching rods 5 are vertically arranged on the cross plate 4, and the punching rods 5 correspond to the assembly seat 3. Among them, the manual crimping machine is a prior art product and will not be described in detail. A T-slot is provided on the workbench of the manual crimping machine, and a T-block is slidably arranged in the T-slot. A threaded blind hole is provided on the top of the T-block, and a threaded through hole is provided on the base. Bolts pass through the bolt through hole and the threaded blind hole to detachably fix the base on the workbench.

[0016] In order to prevent the slide bar from sliding down and crushing the operator when the manual crimping machine fails, the assembly seat is movably arranged on the top of the base. Figure 1 , Figure 2As shown, the top front side and the rear side of the base 2 are respectively provided with a fixed block 10, and a guide rod 11 is provided between the two fixed blocks 10. The assembly seat 3 is provided on the guide rod 11 and can move back and forth. The fixed block 10 located at the rear side of the base 2 is threadedly connected with a limit bolt 12, and the limit bolt 12 is horizontally penetrated on the fixed seat 10, and its front end extends out of the fixed block 10. When not working, the assembly seat is located at the front side of the base, which is convenient for placing the unloading valve joint. After the placement is completed, the assembly seat is pushed backward so that its rear side is pressed against the front end of the limit bolt. At this time, the assembly seat corresponds to the punch rod. Specifically, the punch rod corresponds to the positioning column of the first assembly seat or the contoured groove of the second assembly seat; after the assembly is completed, the assembly seat is pulled forward to be located at the front side of the base, and the unloading valve joint is taken out. The limit thread is used to adjust the position of the assembly seat moving backward, which is convenient for the punch rod to correspond to the positioning column of the first assembly seat or the contoured groove of the second assembly seat.

[0017] At the same time, in order to facilitate the back and forth pulling of the assembly seat, a pull rod 13 is provided on the front side of the assembly seat 3. The front and rear positions of the assembly seat on the base can be adjusted forward and backward by the pull rod, so as to facilitate the alignment of the positioning column or the contoured groove on the top of the base with the punching rod.

[0018] Since the unloading valve joint has two specifications, one is an L-shaped elbow joint, which has a barrel portion that matches the outer ring, an L-shaped tube body with a smaller diameter located above the barrel portion, and a mounting portion connected to the other end of the L-shaped tube body, and the mounting portion is arranged vertically relative to the barrel portion; the other is a straight pipe joint, one end of which is the same as the barrel portion of the elbow joint, and is used to assemble the outer ring; the outer ring is a barrel with a stepped outer side, and the outer ring is embedded in the barrel portion of the elbow joint and the straight pipe joint, respectively, and has an interference fit with it. Correspondingly, there are two types of assembly seats, one is a first assembly seat for assembling the elbow joint and the outer ring, and the other is a second assembly seat for assembling the straight pipe joint and the outer ring, and the assembly methods of the two are slightly different. By replacing the assembly seat, the assembly of the two joints and the outer ring can be realized respectively. Of course, in actual use, in order to save trouble and labor, two crimping machines will be used to assemble different assembly seats respectively to realize the assembly of the two joints and the outer ring.

[0019] Specifically, Figure 1As shown, the assembly seat 3 is a first assembly seat 31, and positioning seats 6 are respectively arranged on the left and right sides of the top of the first assembly seat 31. A U-shaped groove 7 running through the front and rear side walls is opened on the top of the positioning seat 6, and a positioning column 8 is arranged on the top of the first assembly seat 31 located on the front side of the positioning seat 6, and the positioning column 8 corresponds to the U-shaped groove 7 front to back; the bottom front end of the punching rod 5 is an arc-shaped piece 51, and the arc-shaped piece 51 is bent toward the front side, and the arc-shaped piece is adapted to the vertical tube body curvature of the L-shaped tube body of the elbow joint, and the arc-shaped piece 51 corresponds to the positioning column 5. When in use, place the outer ring on the positioning column, place the elbow joint on the outer ring, its barrel portion corresponds to the outer ring, and its mounting portion is stuck in the U-shaped groove. Push the first assembly seat backward so that its rear side surface presses the front end of the limit bolt, and pull the handle of the manual crimping machine to the lowest end. At this time, the arc-shaped piece of the punching rod presses downward on the top surface of the barrel portion of the elbow joint, so that the outer ring is pressed into the inner side of the barrel portion of the elbow joint.

[0020] like Figure 2 As shown, the assembly seat is the second assembly seat 31', and the left and right sides of the top of the second assembly seat 31' are respectively provided with profiling grooves 9, which are adapted to the shape of the straight pipe joint and are convenient for inverting the straight pipe joint. The bottom of the punching rod 5 is a disc 51', and the disc 51' corresponds to the profiling groove 9. When in use, the straight pipe joint is placed vertically upside down in the profiling groove, at which time the barrel of the straight pipe joint is partially located outside the profiling groove, and then the outer ring is placed vertically upside down in the barrel of the straight pipe joint, and the outer ring can be partially embedded in the inner side of the barrel of the straight pipe joint, and the second assembly seat is pushed backward so that its rear side is pressed against the front end of the limit bolt, and the handle of the manual crimping machine is pulled to the lowest end. At this time, the disc of the punching rod presses the outer ring downward, so that the outer ring is pressed into the inner side of the barrel of the straight pipe joint.

[0021] The layout process of this assembly tool is: first assemble the fixed block, guide rod, limit bolt and assembly seat on the base, then fix the base on the workbench of the manual crimping machine, adjust the rearward position of the assembly seat by the limit bolt, pull the assembly seat forward, place the joint and outer ring, and then push the assembly seat to the rearmost side, manually press the handle of the crimping machine to move the slide rod downward, and then press the punch rod downward to realize the assembly of the joint and the outer ring.
