[0018] like Figure 1 , Figure 2 As shown, a retaining spring assembly fixture structure includes a mounting base 1, a positioning fixture 2, a cylinder 3, a retaining spring placement seat 4, and a retaining spring push block 5;

[0019] The positioning fixture 2 includes a product mounting seat 21 and a spring push block slide 22. The positioning fixture 2 is installed on the mounting base 1. The cylinder 3 is fixedly installed on one end of the positioning fixture 2. One end of the spring push block 5 is fixedly installed on the cylinder 3, and the other end is accommodated in the spring push block slide 22. The spring push block 5 slides in the spring push block slide 22 driven by the cylinder 3. The bottom of the product mounting seat 21 is connected to the spring push block slide 22.

[0020] The retaining spring placement seat 4 is installed on the side wall of the retaining spring push block slot 22 and is located between the product mounting seat 21 and the retaining spring push block 5. The distance between the retaining spring placement seat 4 and the bottom of the retaining spring push block slot 22 is the thickness of a retaining spring 6.

[0021] In one embodiment, a retaining spring placement slot 41 is formed on the retaining spring placement seat 4 , and a plurality of retaining springs 6 are stacked and accommodated in the retaining spring placement slot 41 .

[0022] In one embodiment, the end of the retaining spring push block 5 close to the retaining spring placement seat 4 has a notch 51 , and the shape of the notch 51 is adapted to the shape of the outer edge of the retaining spring 6 .

[0023] In one embodiment, the positioning fixture 2 has a pressing plate 23 , and the pressing plate 23 is located on the top of the retaining spring push block 5 .

[0024] In one embodiment, a shaft receiving hole 211 is provided at the bottom of the product mounting seat 21 for receiving the rotating shaft.

[0025] In one of the embodiments, the thickness of one end of the retaining spring push block 5 close to the retaining spring placement seat 4 matches the thickness of the retaining spring 6 .

[0026] The mounting base 1 can be a plate-like structure, so that the positioning fixture 2 is mounted on the mounting base 1. The positioning fixture 2 includes a product mounting seat 21 and a spring push block slide 22. The product mounting seat 21 is used to place the air cylinder 7. One end of the rotating shaft of the air cylinder 7 that needs to be sleeved with the spring 6 is accommodated in the shaft body accommodating hole 211. The spring push block 5 can be dragged by the cylinder 3 to slide in the spring push block slide 22. The spring push block slide 22 is connected to the product mounting seat 21. The spring placement seat 4 is installed on the side wall of the spring push block slide 22 of the positioning fixture 2 and is located between the product mounting seat 21 and the spring push block 5. The distance between the spring placement seat 4 and the bottom of the spring push block slide 22 is the thickness of a spring 6. Several springs 6 are sleeved in the spring placement groove 41 in sequence and can slide on the spring placement groove 41. The spring 6 at the bottom can be separated from the spring placement groove 41, and the spring push block 5 pushes the spring 6 to slide in the spring placement groove 41.

[0027] When the clamping spring 6 needs to be sleeved on the rotating shaft of the pumping cylinder 7, the cylinder 3 is started, and the cylinder 3 pushes the clamping spring push block 5 to slide in the clamping spring push block slideway 22, thereby pushing the clamping spring 6 to move in the direction of the pumping cylinder 7 until the clamping spring 6 is clamped on the rotating shaft of the pumping cylinder 7. At this time, the top surface of the clamping spring push block 5 abuts against the bottom surface of the clamping spring placement seat 4. After the clamping spring is placed on the seat 4, the cylinder 3 pulls the clamping spring push block 5 to slide in the clamping spring push block slideway 22 in the direction away from the pumping cylinder 7. When the clamping spring push block 5 is separated from the bottom surface of the clamping spring placement seat 4, the bottommost clamping spring 6 on the clamping spring placement seat 4 falls into the clamping spring push block slideway 22, ready for the next sleeve connection.

[0028] In this way, the retaining spring assembly fixture structure, through the coordinated arrangement of the cylinder 3, the retaining spring placement seat 4, the retaining spring push block 5, the product mounting seat 21 and the retaining spring push block slide 22, places the retaining spring 6 in the retaining spring placement seat 4, the retaining spring 6 at the bottom is placed in the retaining spring push block slide 22, and the pumping cylinder 7 is placed in the product mounting seat 21, and the cylinder 3 is started to push the retaining spring push block 5. During the sliding process of the retaining spring push block 5 in the retaining spring push block slide 22, the retaining spring 6 is pushed to move in the direction of the pumping cylinder 7 until the retaining spring 6 is clamped on the shaft of the pumping cylinder 7, and the entire assembly process is automatically completed, and the retaining spring 6 is quickly assembled on the pumping cylinder 7.

[0029] In one embodiment, the end of the retaining spring push block 5 close to the retaining spring placement seat 4 has a notch 51 , and the shape of the notch 51 is adapted to the shape of the outer edge of the retaining spring 6 .

[0030] In this way, the open end of the clamping spring 6 faces the direction of the inflating cylinder 7, and the shape of the side of the clamping spring 6 facing away from the open end matches the shape of the notch 51, so that the clamping spring push block 5 can push the clamping spring 6 to move.

[0031] In one embodiment, the positioning fixture 2 has a pressing plate 23 , and the pressing plate 23 is located on the top of the retaining spring push block 5 .

[0032] In this way, by setting the pressure plate 23, it is possible to effectively prevent the retaining spring push block 5 from falling out of the retaining spring push block slide groove 22 during the sliding process in the retaining spring push block slide groove 22, thereby ensuring that the assembly work of the retaining spring 6 proceeds normally.

[0033] In one of the embodiments, the thickness of one end of the retaining spring push block 5 close to the retaining spring placement seat 4 matches the thickness of the retaining spring 6 .

[0034] In this way, the distance between the bottom of the retaining spring placement seat 4 and the bottom of the retaining spring push block slide groove 22 is the thickness of a retaining spring 6, so the retaining spring push block 5 is adapted to the thickness of the retaining spring 6, which can facilitate the retaining spring push block 5 to pass through the bottom of the retaining spring placement seat 4 during the sliding process, and at the same time, it can also abut against the retaining spring 6 on the retaining spring placement seat 4 to prevent the retaining spring 6 from falling from the retaining spring placement seat 4.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
