[0043] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0044] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.
[0045] like Figures 1 to 5 As shown, the first exemplary embodiment of the present application provides a wire retaining ring installation device, which mainly includes a first sleeve 1 and a first push rod 2.
[0046] The first sleeve 1 is used to be inserted into the through hole 7 of the workpiece, such as the valve body through hole of the hydraulic valve, and the barrel cavity of the first sleeve 1 includes a retaining ring cavity section 101 located at the sleeve insertion end of the first sleeve 1. As the name implies, the retaining ring cavity section 101 can accommodate the wire retaining ring 6, and the wire retaining ring can be brought into the workpiece through hole 7 by using the first sleeve 1. The first push rod 2 is used to be inserted into the first sleeve 1, and can move along the axial direction of the first sleeve 1 and rotate around its own axial direction. In addition, the push rod insertion end of the first push rod 2 is formed with a first inclined end face 201 inclined relative to its own axial direction.
[0047] Therefore, for the wire retaining ring 6 with a larger diameter, higher hardness and poor shrinkage and deformation ability, when the first push rod 2 is inserted into the first sleeve 1, the wire retaining ring 6 can be compressed along its own radial direction to cause slight deformation, and then the wire retaining ring 6 is adjusted to a state parallel to the first inclined end face 201, and the wire retaining ring 6 can be installed into the retaining ring cavity section 101. At this time, the peripheral wall of the wire retaining ring 6 is pressed against the peripheral wall of the retaining ring cavity section 101, thereby generating a certain friction force, so that the wire retaining ring 6 is positioned in the retaining ring cavity section 101. In other words, when the first push rod 2 is inserted into the first sleeve 1 and the wire retaining ring 6 is accommodated, the wire retaining ring 6 can be parallel to the first inclined end face 201 and compressed along its own radial direction.
[0048] After the first sleeve 1 containing the wire retaining ring 6 is inserted into the workpiece through hole 7, the first push rod 2 is pushed to move along the axial direction of the first sleeve 1, thereby driving the wire retaining ring 6 located in the retaining ring cavity section 101 to move to the Figure 5 In the state a shown in the figure, the leading end of the wire retaining ring 6 first moves to the retaining ring groove 701 located in the workpiece through hole 7, but at this time the wire retaining ring 6 is still in a state parallel to the first inclined end face 201, that is, inclined to the retaining ring groove 701, and for this purpose, the first push rod 2 is rotated around its own axis to rotate the first inclined end face 201 to push the wire retaining ring 6 to swing to Figure 5 The state b shown is that the steel wire retaining ring 6 is moved into the retaining ring slot 701 as a whole, thereby completing the installation process of the steel wire retaining ring 6 and meeting the assembly requirements of the steel wire retaining ring with large diameter and high hardness. In the above process, the first push rod 2 only needs to push the steel wire retaining ring 6 along the retaining ring cavity section 101, and the overall pushing stroke is short, thereby reducing the difficulty of assembling the steel wire retaining ring 6 and reducing the friction and wear between the steel wire retaining ring 6 and the wall surface of the barrel cavity of the first sleeve 1.
[0049] In an optional or preferred embodiment, Figure 1 As shown, the sleeve insertion end of the first sleeve 1 can be formed as a stepped hole, that is, the wall thickness of the sleeve insertion end is smaller than the wall thickness of the rest of the barrel. In this way, the stepped hole itself can be formed into the above-mentioned retaining ring cavity section 101, and the larger wall thickness of the rest of the barrel can reduce the overall processing difficulty of the first sleeve 1, and at the same time can reduce the risk of the first sleeve 1 being deformed due to pressure.
[0050] In the case where the sleeve insertion end of the first sleeve 1 is formed as a stepped hole, as Figure 1As shown, the other end of the first push rod 2 opposite to the push rod insertion end can be formed as a push rod driving end, wherein the diameter of the push rod insertion end can be set to be larger than the diameter of the push rod driving end and equal to the diameter of the stepped hole. Thus, in the process of inserting the first push rod 2 into the first sleeve 1, the push rod driving end can be inserted from the stepped hole until the push rod insertion end moves into the stepped hole and is limited in the stepped hole, so that when the wire retaining ring 6 is installed into the retaining ring cavity section 101, it can fit the first inclined end surface 201 to maintain the inclined state.
[0051] In an optional or preferred embodiment, Figure 4 As shown, when the first sleeve 1 is inserted into the workpiece through hole 7, the peripheral end surface of the retaining ring cavity section 101 can be flush with the side wall surface of the retaining ring groove 701. In other words, in the process of inserting the first sleeve 1 into the workpiece through hole 7, the first sleeve 1 moves along the axial direction of the workpiece through hole 7 until the end surface of the sleeve plug-in end of the first sleeve 1 is flush with the side wall surface of the retaining ring groove 701, that is, the peripheral end surface of the retaining ring cavity section 101 is flush with the side wall surface of the retaining ring groove 701, and the first sleeve 1 can stop moving further. When the peripheral end surface of the retaining ring cavity section 101 is flush with the side wall surface of the retaining ring groove 701, during the process in which the first push rod 2 pushes the wire retaining ring 6 located in the retaining ring cavity section 101 to move to the retaining ring groove 701, the wire retaining ring 6 can move throughout the first sleeve 1 until it moves into the retaining ring groove 701, thereby avoiding contact between the wire retaining ring 6 and the inner wall surface of the workpiece through hole 7 and causing wear on both sides.
[0052] In order to enable the first sleeve 1 to be accurately inserted into the appropriate position of the workpiece through hole 7, the other end of the first sleeve 1 opposite to the sleeve insertion end is formed as a sleeve limiting end, and the sleeve limiting end is provided with a positioning plate portion 102 for docking and positioning the peripheral end face of the workpiece through hole 7. The key is that the length between the inner wall surface of the positioning plate portion 102 and the end face of the sleeve limiting end can be set to be equal to the length between the peripheral end face of the workpiece through hole 7 and the side wall surface of the retaining ring groove 701. In this way, in the process of inserting the first sleeve 1 into the workpiece through hole 7, when the positioning plate portion 102 abuts against the peripheral end face of the workpiece through hole 7, the first sleeve 1 can stop moving. At this time, the peripheral end face of the retaining ring cavity section 101 of the first sleeve 1 is just flush with the side wall surface of the retaining ring groove 701, thereby realizing the precise insertion of the first sleeve 1. In this embodiment, the first sleeve 1 can form a threaded fit with the workpiece through hole 7, that is, the outer wall of the first sleeve 1 and the inner wall of the workpiece through hole 7 are respectively provided with mutually matching threads, thereby facilitating the insertion and positioning of the first sleeve 1.
[0053] In an optional or preferred embodiment, Figure 2As shown, the wire retaining ring installation device also includes a second sleeve 3 and a second push rod 4. The second sleeve 3 is used to coaxially dock with the sleeve insertion end of the first sleeve 1. The barrel cavity of the second sleeve 3 includes a compression chamber section 301 whose cavity diameter decreases along the axial direction of the second sleeve 3. The diameter of the narrow end of the compression chamber section 301 is consistent with the diameter of the retaining ring cavity section 101. The second push rod 4 is used to be inserted into the second sleeve 3 and can move along the axial direction of the second sleeve 3.
[0054] It should be noted that the diameter of the wide end of the compression chamber section 301 is larger than the diameter of the wire retaining ring 6 , so as to facilitate the placement of the wire retaining ring 6 into the compression chamber section 301 from the wide end.
[0055] In this way, in the process of installing the wire retaining ring 6 into the retaining ring cavity section 101 of the first sleeve 1, the second sleeve 3 can be coaxially connected with the sleeve insertion end of the first sleeve 1, so that the narrow end of the compression chamber section 301 is aligned and connected with the retaining ring cavity section 101, and then the wire retaining ring 6 is placed into the compression chamber section 301 from the wide end of the compression chamber section 301 so that it is accommodated in the compression chamber section 301, and then the second push rod 4 is inserted into the second sleeve 3 from the wide end of the compression chamber section 301, so that the second push rod 4 can push the wire retaining ring 6 located in the compression chamber section 301 toward the narrow end, and the wire retaining ring 6 is gradually compressed and deformed during the movement, and further moves into the retaining ring cavity section 101 of the first sleeve 1, thereby completing the process of installing the wire retaining ring 6 into the first sleeve 1.
[0056] Furthermore, the interpenetrating end of the second push rod 4 is formed with a second inclined end face 401 which is inclined relative to its own axial direction, and the inclination of the second inclined end face 401 is consistent with the inclination of the first inclined end face 201. Therefore, for the wire retaining ring 6 with a large diameter, high hardness, and poor shrinkage and deformation ability, in the process of using the second push rod 4 to push the wire retaining ring 6 to move, the second inclined end face 401 fits the end face of the wire retaining ring 6, so that the wire retaining ring 6 is adjusted to an inclined state parallel to the second inclined end face 401. In this way, in the pushing process, it is only necessary to keep the second inclined end face 401 and the first inclined end face 201 parallel to each other, so that the wire retaining ring 6 can be pushed into the retaining ring cavity section 101 in an inclined posture parallel to the first inclined end face 201, and there is no need to adjust the posture of the wire retaining ring 6 later, thereby improving assembly efficiency.
[0057] In an optional or preferred embodiment, the barrel cavity of the second sleeve 3 also includes a guide cavity section connected to the narrow end of the compression cavity section 301, and the diameter of the guide cavity section is equal to the diameter of the narrow end. Therefore, in the process of the second push rod 4 pushing the wire retaining ring 6 along the barrel cavity of the second sleeve 3, the wire retaining ring 6 is first compressed by the compression cavity section 301, and then enters the guide cavity section. In the guide cavity section, the posture of the wire retaining ring 6 can be fine-tuned. Under the push of the second push rod 4, the wire retaining ring 6 can be adjusted to be completely parallel to the second inclined end face 401 of the second push rod 4; in the state where the second sleeve 3 and the sleeve insertion end of the first sleeve 1 are coaxially connected, under the push of the second push rod 4, the wire retaining ring 6 can smoothly transition from the guide cavity section to the retaining ring cavity section 101 of the first sleeve 1 to avoid jamming.
[0058] In an optional or preferred embodiment, referring to Figure 2 and Figure 3 The barrel cavity of the second sleeve 3 also includes a sleeve cavity section 302 connected to the narrow end of the compression chamber section 301, and the diameter of the sleeve cavity section 302 is larger than the diameter of the narrow end. When the second sleeve 3 is coaxially connected with the sleeve insertion end of the first sleeve 1, the sleeve insertion end of the first sleeve 1 is inserted in the sleeve cavity section 302. At this time, the retaining ring cavity section 101 of the first sleeve 1 is connected to the narrow end of the compression chamber section 301, and the wall surface of the retaining ring cavity section 101 is connected to the wall surface of the compression chamber section 301, so that under the push of the second push rod 4, the wire retaining ring 6 can move smoothly from the compression chamber section 301 to the retaining ring cavity section 101.
[0059] In some other embodiments, the barrel cavity of the second sleeve 3 may include a compression chamber section 301, a guide chamber section and a sleeve chamber section 302 connected in sequence, wherein the guide chamber section is connected to the narrow end of the compression chamber section 301. In this case, when the sleeve insertion end of the first sleeve 1 is inserted into the sleeve chamber section 302, the retaining ring chamber section 101 of the first sleeve 1 can be aligned and connected with the guide chamber section, and the wire retaining ring 6 can first pass through the compression chamber section 301 for compression under the push of the second push rod 4, and then pass through the guide chamber section for fine-tuning of posture and linear movement, and finally enter the retaining ring chamber section 101 seamlessly.
[0060] In the illustrated embodiment, when the first sleeve 1 is inserted into the second sleeve 3, the sleeve insertion end of the first sleeve 1 forms a clearance fit with the sleeve cavity section 302, thereby achieving mutual locking of the two. In other embodiments, the first sleeve 1 and the second sleeve 3 can also be connected to each other through threaded fit, and after the wire retaining ring 6 is pushed into the first sleeve 1, the first sleeve 1 and the second sleeve 3 can be easily and quickly disassembled, thereby improving assembly efficiency.
[0061] In an optional or preferred embodiment, referring to Figure 1 and Figure 4The other end of the first push rod 2 opposite to the push rod insertion end is formed as a push rod driving end, and the peripheral wall of the push rod driving end is provided with a push rod pin hole 202, and the wire retaining ring installation device includes a push rod pin shaft (not shown in the drawings) for passing through the push rod pin hole 202. When the wire retaining ring 6 initially enters the retaining ring slot 701 and requires swing adjustment, as shown in FIG. Figure 5 The stage of adjusting from state a to state b shown in the figure requires rotating the first push rod 2 to push the wire retaining ring 6 to completely fall into the retaining ring slot 701. At this time, the push rod pin can be inserted into the push rod pin hole 202. By pushing the push rod pin, the first push rod 2 can be driven to rotate around its own axis with little effort.
[0062] In an optional or preferred embodiment, Figure 4 As shown, the wire retaining ring installation device also includes a limiting rod 5, which is used to be inserted into the workpiece through hole 7. When the limiting rod 5 is inserted into the workpiece through hole 7, the end face of the inserted end of the limiting rod 5 is flush with the side wall surface of the retaining ring slot 701. Therefore, after the first push rod 2 is used to push the wire retaining ring 6 into the retaining ring slot 701, under the limiting action of the limiting rod 5, the wire retaining ring 6 cannot move further, so that it falls into the retaining ring slot 701 accurately, avoiding the excessive thrust of the first push rod 2 causing the wire retaining ring 6 to be pushed out of the retaining ring slot 701.
[0063] It should be noted that in this exemplary embodiment, the limiting rod 5 can be inserted into the workpiece through hole 7 by threaded cooperation, and at the same time, the first sleeve 1 can also be inserted into the workpiece through hole 7 by threaded cooperation, thereby improving the connection tightness of the above three.
[0064] The second exemplary embodiment of the present application further provides a wire retaining ring installation method, which uses the above-mentioned wire retaining ring installation device and includes:
[0065] S1: inserting the first push rod 2 into the first sleeve 1;
[0066] S2: placing the wire retaining ring 6 parallel to the first inclined end surface 201 of the first push rod 2 and compressing it in its own radial direction, and pushing it into the retaining ring cavity section 101 at the sleeve insertion end of the first sleeve 1;
[0067] S3: insert the first sleeve 1 into the workpiece through hole 7, and drive the wire retaining ring 6 to move along the retaining ring cavity section 101 to the retaining ring slot 701 by pushing and rotating the first push rod 2.
[0068] In the above step S3, the following steps may be performed:
[0069] S3′: first push the first push rod 2 to drive the wire retaining ring 6 to move, until the leading end of the wire retaining ring 6 moves to the retaining ring slot 701, and then rotate the first push rod 2 to drive the wire retaining ring 6 to swing, until the trailing end of the wire retaining ring 6 swings into the retaining ring slot 701.
[0070] Or perform the following steps:
[0071] S3”: Push the first push rod 2 to drive the wire retaining ring 6 to move until the leading end of the wire retaining ring 6 is about to move to the retaining ring slot 701, and rotate the first push rod 2 while pushing the first push rod 2, so as to drive the wire retaining ring 6 to move as a whole into the retaining ring slot 701.
[0072] In practical applications, step S3' or step S3" may be selected according to the convenience and accuracy requirements of the actual operation, and this application does not limit this.
[0073] In an optional or preferred embodiment, the wire retaining ring installation method further comprises the following steps:
[0074] Before inserting the sleeve insertion end into the workpiece through hole 7, the sleeve insertion end is coaxially docked with the second sleeve 3 so that the compression chamber section 301 of the second sleeve 3 and the retaining ring chamber section 101 are connected to each other;
[0075] The wire retaining ring 6 is placed into the compression chamber section 301 , and the wire retaining ring 6 is pushed along the compression chamber section 301 into the retaining ring receiving chamber section 101 by the second push rod 4 .
[0076] In a specific embodiment, the specific process of installing the wire retaining ring 6 into the workpiece through hole 7 is as follows:
[0077] Step 1: insert the first push rod 2 into the first sleeve 1, so that the inserted end of the first push rod 2 is in the retaining ring cavity section 101, then insert the first sleeve 1 into the second sleeve 3, and then put the wire retaining ring 6 into the compression cavity section 301 of the second sleeve 3;
[0078] Step 2: Insert the second push rod 4 into the compression chamber section 301, and move the second inclined end surface 401 in contact with the wire retaining ring 6, so as to push the wire retaining ring 6 into the retaining ring chamber section 101 of the first sleeve 1 in an inclined posture, as shown in FIG. Figure 3 As shown, until the wire retaining ring 6 is attached to the first inclined end surface 201 of the first push rod 2;
[0079] Step 3: Insert the limit rod 5 into one end of the workpiece through hole 7, then pull the first sleeve 1 out of the second sleeve 3 and insert the first push rod 2 and the wire retaining ring 6 into the other end of the workpiece through hole 7, and then push the first push rod 2 until the first push rod 2 cannot be pushed. At this time, the leading end of the wire retaining ring 6 falls into the retaining ring slot 701, as shown in FIG. Figure 5 State a shown;
[0080] Step 4: Rotate the first push rod 2 to rotate the first inclined end surface 201, thereby pushing the wire retaining ring 6 to swing until the wire retaining ring 6 completely enters the retaining ring slot 701.

[0081] Step 5: Remove the limiting rod 5 and the second sleeve 3 together with the first push rod 2 from the workpiece through hole 7 .
