All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Currently, the drilling process for elastic retaining rings typically involves first marking lines on the part for positioning, and then drilling holes at the marked lines. This method has the following drawbacks: 1. Marking lines on each product results in low processing efficiency; 2. During processing, the drill bit vibrates with the drilling machine, and since there is no positioning or guidance for the drill bit, it is prone to breakage. Therefore, a new tooling for drilling elastic retaining rings needs to be designed to solve these problems.

[0027] This utility model provides, for example Figures 1 to 6 The invention relates to a drilling fixture for an elastic retaining ring, which is used for clamping the elastic retaining ring. It includes a support fixture 1, a clamping fixture 2 at the top of the support fixture 1, and a retaining ring 3 placed between the support fixture 1 and the clamping fixture 2. The top of the support fixture 1 has an installation groove 102 for placing the workpiece.

[0028] When in use, the support fixture 1 is placed in the designated position, which is the drilling area of ​​the retaining ring 3. The mounting groove 102 on the support fixture 1 is used to place the retaining ring 3. Then the clamping fixture 2 clamps the retaining ring 3.

[0029] During drilling, the support fixture 1 supports the retaining ring 3, and the clamping fixture 2 determines and fixes the installation position of the retaining ring 3. Then, the tooling personnel drill the retaining ring 3 through the guide hole 204 of the clamping fixture 2. Afterwards, the staff uses external tools or other methods to prevent the retaining ring 3 from moving or shifting during drilling, and to ensure the consistency of drilling the retaining ring 3.

[0030] A support plate 103 is provided at one end of the support fixture 1 near the clamping fixture 2. One side of the support plate 103 is an arc surface, which is a contact surface 101. An installation groove 102 is formed between the contact surface 101 and the support plate 103.

[0031] The highest point of the mounting groove 102 is lower than the highest point of the support plate 103.

[0032] In use, the support plate 103 of the support fixture 1 supports the clamping fixture 2. The support plate 103 is the highest point of the support fixture 1, ensuring that the retaining ring 3 can be placed between the clamping fixture 2 and the support fixture 1. The contact surface 101 of the support fixture 1 is an arc surface that fits against the inner side wall of the retaining ring 3, increasing the stability of the retaining ring 3 during the support process.

[0033] The mounting groove 102 is located between the support plate 103 and the contact surface 101, and the insert portion 303 of the retaining ring 3 is installed inside the mounting groove 102.

[0034] The mounting groove 102 is a semi-open groove formed by the recess of the base of the supporting tooling 1, and the junction of the mounting groove 102 and the contact surface 101 is rounded.

[0035] In use, the depth of the recess in the mounting groove 102 is the same as the height of the protrusion in the insert portion 303 of the retaining ring 3, which helps to improve the stability of the insert portion 303 and the mounting groove 102. The junction of the mounting groove 102 and the contact surface 101 is rounded, and the junction of the elastic ring 301 and the insert portion 303 is a recessed groove with an arc-shaped bottom. The recessed groove and the junction of the mounting groove 102 and the contact surface 101 are engaged, so that the retaining ring 3 is more stably installed inside the mounting groove 102.

[0036] The clamping fixture 2 includes a mounting plate 201, and a base is provided at one bottom side of the mounting plate 201. The base is composed of a protrusion 205 and a vertical plate 202.

[0037] In use, the mounting plate 201 of the clamping fixture 2 is connected to the support plate 103. The support plate 103 supports one side of the bottom end of the mounting plate 201 to ensure the distance between the mounting plate 201 and the support fixture 1.

[0038] The base of the mounting plate 201 fits into the end face of the support fixture 1, and the base is formed by the protrusion 205 and the upright plate 202.

[0039] A groove 203 is provided between the protrusion 205 and the upright plate 202. The outer side of the protrusion 205 is the side of the groove 203, and the side of the groove 203 near the upright plate 202 is the intersecting surface 206.

[0040] The bottom end of the groove 203 is in contact with the intersection line of the mounting groove 102 and the contact surface 101, and the intersecting surface 206 is in contact with the contact surface 101.

[0041] The end face of the protrusion 205 is provided with a guide hole 204, and the bottom end of the protrusion 205 fits into the interior of the mounting groove 102.

[0042] In use, the bottom end of the protrusion 205 is an arc surface that fits against the bottom end of the mounting groove 102. The protrusion 205 is engaged with the mounting groove 102. After engagement, the protrusion 205 has two functions: function 1, to support the mounting plate 201 and prevent the mounting plate 201 from tilting, which would affect the installation of the retaining ring 3; function 2, after engagement with the mounting groove 102, the guide hole 204 of the protrusion 205 determines the position of the hole in the retaining ring 3, ensuring the consistency of the hole in the retaining ring 3.

[0043] The groove 203 engages with the mounting groove 102 and the contact surface 101 at the junction, increasing the stability of the base and further increasing the stability of the mounting plate 201. The intersecting surface 206 of the groove 203 fits into the contact surface 101, so that the base fits into the end face of the support fixture 1.

[0044] The mounting groove 102 contains a workpiece, which is a retaining ring 3. The retaining ring 3 includes an elastic ring 301. The two ends of the elastic ring 301 are provided with an embedding part 303. The end face of the embedding part 303 is provided with a drill hole 302.

[0045] The embedded part 303 is located inside the mounting groove 102. The drill hole 302 of the embedded part 303 is coaxial with the guide hole 204. The arc surface of the inner wall of the elastic ring 301 is in contact with the contact surface 101.

[0046] When in use, after the clamping fixture 2 is installed on the end face of the support fixture 1, the insert 303 is snapped into the inside of the mounting groove 102. The arc surface at the bottom of the insert 303 fits with the arc at the bottom of the mounting groove 102. At this time, the bottom of the insert 303 is coaxial with the bottom of the protrusion 205 and fits with the arc at the bottom of the mounting groove 102, ensuring that the drilling position of the retaining ring 3 is consistent.

[0047] After the insert 303 is installed inside the mounting groove 102, the arc surface of the side wall of the elastic ring 301 fits against the contact surface 101, increasing the stability of the retaining ring 3 installation.

[0048] Working principle

[0049] The support fixture 1 is placed in the designated position, which is the area where the retaining ring 3 is drilled. Then, the clamping fixture 2 is placed on the top of the support plate 103 of the support fixture 1. The base of the clamping fixture 2 is in contact with the end face of the support fixture 1. The bottom end of the protrusion 205 is an arc surface that fits with the bottom end of the mounting groove 102. The protrusion 205 is engaged with the mounting groove 102. The groove 203 is engaged with the junction of the mounting groove 102 and the contact surface 101. Then, the side of the groove 203 near the vertical plate 202 is the intersecting surface 206, which fits with the contact surface 101 to increase the stability of the base.

[0050] Secondly, after the support fixture 1 and clamping fixture 2 are installed, a space is formed between the support fixture 1 and clamping fixture 2 for the installation of the retaining ring 3. The retaining ring 3 is placed inside the space, and the embedded part 303 of the retaining ring 3 is installed inside the mounting groove 102. The junction of the elastic ring 301 and the embedded part 303 is a recessed groove. The recessed groove and the junction of the mounting groove 102 and the contact surface 101 are engaged. The arc surface of the side wall of the elastic ring 301 fits against the contact surface 101, increasing the stability of the retaining ring 3 installation. At this point, the retaining ring 3 is installed.

[0051] Finally, when drilling is required, the staff uses external tools or other methods to fix the retaining ring 3 on the side away from the base to prevent the retaining ring 3 from moving or shifting during drilling, to ensure the consistency of drilling the retaining ring 3, and to ensure that the drill hole 302 for drilling the retaining ring 3 is coaxial with the guide hole 204. After the staff has fixed the other side, the drilling mechanism drills the retaining ring 3 through the guide hole 204.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
