Description

Technical Field

[0001] This application relates to the technical field of retaining ring processing, and in particular to a retaining ring clamping device. Background Art

[0002] Currently, the retaining ring processing process is mainly carried out by wire cutting. First, the retaining rings are stacked on the tooling fixture, and then pulse spark discharge machining is performed. After the pulse spark discharge machining is completed, the pressure plate is manually loosened to remove the workpiece, and the next process cycle is carried out. During the working process, since only 5 retaining rings can be processed each time, the efficiency is low. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, one of the purposes of this application is to provide a retaining ring clamping device, which has the advantage of high efficiency.

[0004] The above object of this application is achieved through the following technical solutions:

[0005] A retaining ring clamping device includes a bottom plate. At least one positioning post is provided on the bottom plate. A pressing component is provided on the positioning post. The retaining ring is sleeved on the positioning post and is pressed by the pressing component. The pressing component includes a pressure plate and a fixing member. The fixing member is used to fix the pressure plate on the positioning post. The pressure plate and the positioning post are detachably connected. Shifting grooves are provided on the pressure plate and the positioning post.

[0006] By adopting the above technical solution, during use, the retaining ring is sleeved on the positioning post, and then the pressure plate is used to press multiple retaining rings, so that multiple retaining rings can be fixed, and the processing efficiency is relatively high.

[0007] In a preferred example of this application, it can be further configured that: a relief groove is further provided on the bottom plate. The relief groove penetrates through the bottom plate. The relief groove corresponds to the positioning post.

[0008] By adopting the above technical solution, the existence of the relief groove enables the molybdenum wire to pass through the bottom plate to process the retaining ring.

[0009] In a preferred example of this application, it can be further configured that: the width of the relief groove is not less than the width of the shifting groove.

[0010] By adopting the above technical solution, it further enables the molybdenum wire to be processed more conveniently.

[0011] In a preferred example of this application, it can be further configured that: mounting holes are provided on the bottom plate. Plugging rods are further provided on the positioning post. The plugging rods are adapted to the mounting holes and are inserted into the mounting holes. The mounting holes are non-circular holes.

[0012] By adopting the above technical solution, for the mounting hole with a non-circular hole, it can play a certain anti-misoperation effect when installing the positioning post on the bottom plate.

[0013] In a preferred example of the present application, it can be further configured as follows: sleeving a certain number of retaining rings on the positioning post, then connecting the pressing plate to the positioning post, adjusting the position of the retaining rings to make them neatly arranged, and then fixedly connecting the pressing plate and the positioning post and pressing the uppermost retaining ring.

[0014] By adopting the above technical solution, when sleeving the retaining rings on the positioning post, the retaining rings are arranged so that they are neatly arranged, and then the retaining rings are compacted and fixed, thereby facilitating the processing of the retaining rings.

[0015] In a preferred example of the present application, it can be further configured as follows: when adjusting the position of the retaining rings, insert the adjusting member into the displacement groove, and through the action of the adjusting member, make the retaining rings move and abut against the positioning post.

[0016] By adopting the above technical solution, by inserting the adjusting member into the displacement groove, making the retaining rings move and abut against the positioning post, a good positioning and arranging effect can be achieved.

[0017] In a preferred example of the present application, it can be further configured as follows: judge whether there is any retaining ring protruding or sunken among the arranged retaining rings. If so, remove the corresponding retaining ring.

[0018] By adopting the above technical solution, that is, when the inner diameter of the retaining ring is too large or too small, when one side of it abuts against the positioning post, the other end will form a protrusion or depression on the vertical plane formed by the other retaining rings. Therefore, in this way, the non-conforming retaining rings can be removed.

[0019] In a preferred example of the present application, it can be further configured as follows: the adjusting member includes an adjusting rod and an adjusting groove, and a deformation layer covers the adjusting groove, and the deformation layer is used to contact the retaining ring under the action of pressure.

[0020] By adopting the above technical solution, that is, during the process of adjusting the retaining rings, by introducing gas into the adjusting groove, the presence of the gas causes the deformation layer to deform and contact the retaining ring, thereby achieving the purpose of adjusting the position of the retaining ring.

[0021] In a preferred example of the present application, it can be further configured as follows: after arranging, judge the retaining rings. If there is no retaining ring protruding or sunken, fixedly connect the pressing plate and the positioning post, and make the pressing plate press the uppermost retaining ring. After pressing, cancel the pressure on the deformation layer to make the deformation layer recover, and take out the adjusting member from the displacement groove.

[0022] By adopting the above technical solution, after the position of the retaining ring is adjusted in place, the retaining ring is pressed by the pressing plate, so as to achieve the purpose of fixing the retaining ring. After the retaining ring is fixed, the gas in the adjusting groove is discharged, so that the deformation layer does not contact the retaining ring, and then the adjusting part is taken out from the shifting groove.

[0026] The present application will be further described in detail below with reference to the drawings.

[0027] Refer to Figure 1 and Figure 2 As shown in the figures, a retaining ring clamping device disclosed in the present application includes a bottom plate 1. At least one positioning column 4 is provided on the bottom plate 1. In this embodiment, there are four positioning columns 4. An inserting rod 41 is provided on the positioning column 4. The inserting rod 41 is annular, and more specifically, such as oval or racetrack-shaped. A mounting hole 12 adapted to the inserting rod 41 is provided on the bottom plate 1. The mounting hole 12 is a non-circular hole and penetrates through the bottom plate 1. A relief groove 11 penetrating through the bottom plate 1 is further provided on the bottom plate 1. The relief groove 11 corresponds to the positioning column 4 one by one and is communicated with the corresponding mounting hole 12.

[0028] A downward pressing assembly 2 is further provided on the positioning column 4. The downward pressing assembly 2 includes a pressing plate 21 and a fixing member 22. In this embodiment, the fixing member 22 is a bolt. The pressing plate 21 is fixedly connected to the positioning column 4 by the bolt. Shifting grooves 3 are provided on both the pressing plate 21 and the positioning column 4. The width of the relief groove 11 is not less than the width of the shifting groove 3. In this embodiment, the width of the relief groove 11 is equal to the width of the shifting groove 3.

[0029] When the retaining rings are sleeved on the positioning columns 4, according to production requirements, a certain number of retaining rings are sleeved on the positioning columns 4. At this time, the upper surface of the uppermost retaining ring protrudes from the upper surface of the positioning column 4. Subsequently, the pressing plate 21 is connected to the positioning column 4, so that the pressing plate 21 contacts the retaining ring and applies a force to the retaining ring. At this time, when the retaining ring is subjected to an external force, it can still move;

[0030] Adjust the position of the retaining ring through the adjusting member so that the retaining rings are neatly arranged. The adjusting member includes an adjusting rod and an adjusting groove. A deformation layer is covered on the adjusting groove. The deformation layer can be made of rubber material and can be arc-shaped. The adjusting groove is connected to an external air source. Under the action of the air source, the deformation layer will deform. When the deformation layer contacts the retaining ring, under the action of pressure, the retaining ring moves, and the side of the retaining ring away from the deformation layer abuts against the positioning post 4.

[0031] Judge the arranged retaining rings to see if there are any retaining rings protruding or sunken. If so, remove the corresponding retaining rings. In this step, if the retaining ring is a non-open retaining ring, judge whether there is a retaining ring protruding or sunken from the cylindrical surface formed by other retaining rings. If the retaining ring is an open retaining ring, it can be judged by the degree of deformation of the deformation layer at the opening of the retaining ring. When applied to an open retaining ring, the area of the deformation layer is larger than the width of the adjusting groove, that is, the deformation layer can extend to the opening of the open retaining ring. When the deformation layer is under pressure, it deforms and can finely adjust the opening position of the retaining ring, so that the opening position is more consistent in the vertical direction.

[0032] If there is no retaining ring protruding or sunken, fixedly connect the pressing plate 21 and the positioning post 4, and make the pressing plate 21 press the uppermost retaining ring. After pressing, cancel the pressure on the deformation layer to make the deformation layer recover, and take out the adjusting member from the displacement groove 3.

[0033] The implementation principle of this embodiment is: By sleeving the retaining rings on the positioning posts 4, and then applying pressure to the retaining rings through the pressing plate 21 and fixing them, multiple retaining rings can be processed, thereby improving work efficiency.

[0034] The embodiments of this specific implementation manner are all preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
