Description

Technical Field

[0001] The utility model relates to the field of valve processing auxiliary tools, in particular to a retaining ring processing fixture. Background Art

[0002] The retaining ring is a workpiece commonly used on valves. Since the retaining ring usually needs to be processed (including but not limited to grinding, drilling and tapping) before being assembled on the valve, the retaining ring needs to be in a clamped state during processing. The current tool for clamping the retaining ring is a six-jaw chuck as shown in patent publication CN217801028U. Since the six jaws of this six-jaw chuck are linked, the positions of the six jaws cannot be adjusted according to the specific usage requirements of the six-jaw chuck, so the clamping adaptability of this six-jaw chuck is relatively poor.

[0024] As attached Figure 1 , Attachment Figure 2 And attached Figure 3The invention discloses a retaining ring 5 processing fixture, comprising a chassis 1, on which a slideway 101 is arranged, wherein there are three slideways 101, the distance between two adjacent slideways 101 is equal, and the angle formed between two adjacent slideways 101 is 120 degrees, and the fixture further comprises a clamping jaw 2, each slideway 101 is slidably clamped with a clamping jaw 2, each clamping jaw 2 is provided with a step surface 202, each clamping jaw 2 is provided with a tightening bolt 3, the tightening bolt 3 tightens the outer wall edge of the chassis 1, and the tightening bolt 3 on the clamping jaw 2 arranged on each slideway 101 is parallel to the slideway 101.

[0025] In this type of clamp, three slideways 101 are arranged on the chassis 1, and each slideway 101 is provided with a sliding clamping jaw 2, and each clamping jaw 2 is installed with a tightening bolt 3, and the tightening bolt 3 presses the outer wall edge of the chassis 1, and each slider 4 of this type of clamp is independently adjusted on the slideway 101 of the chassis 1, and the movement of the clamping jaws 2 will not interfere with each other. The step surface 202 on the clamping jaw 2 is used to contact with the chuck. Since the step surface 202 is arranged on the clamping jaw 2, the three clamping jaws 2 on the chassis 1 can be used to clamp retaining rings 5 ​​of different specifications.

[0026] In summary, the positions of the three clamping jaws 2 of the chassis 1 in this clamp can be adjusted independently, there is no interference when the three clamping jaws 2 are adjusted, and the clamping adaptability is stronger.

[0027] It should be noted that this type of clamp is not suitable for installation on a rotating clamping table (the clamp needs to rotate), but is suitable for placement on a platform surface (that is, the clamp does not need to rotate).

[0028] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As described above, the clamping jaw 2 is provided with an extension piece 201 , and the tightening bolt 3 is provided on the extension piece 201 .

[0029] Specifically, the extension piece 201 is located outside the outer wall edge of the bottom plate 1 , and the extension piece 201 does not contact the bottom plate 1 .

[0030] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As described above, each clamping jaw 2 is provided with two parallel tightening bolts 3 .

[0031] The parallel tightening bolts 3 are arranged on the extension piece 201 of each clamping jaw 2 to facilitate the adjustment of the position of the clamping jaw 2 on the chassis 1 .

[0032] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 The device further comprises a slider 4, which is slidably clamped in the slideway 101, and the clamping jaw 2 and the slider 4 are detachably matched together.

[0033] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As described above, the slideway 101 is a T-shaped slideway 101 , and the slider 4 is a T-shaped slider 4 .

[0034] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As described above, the chassis 1 is a ring-shaped chassis 1.

[0036] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As described above, all the tightening bolts 3 are located in one plane.

[0037] Combined with Figure 1 And attached Figure 3 As shown in , the method of using the processing fixture of this retaining ring 5 is as follows. First, slide the jaws 2 on the chassis 1 toward the center (the friction between the slider 4 and the chassis 1 is relatively large, and the slider 4 will not slide on the chassis 1 without a large external force), and tighten the tightening bolt 3 so that the tightening bolt 3 does not contact the outer wall of the chassis 1. When the jaw 2 slides to the point where the extension piece 201 contacts the outer wall of the chassis 1 (this state is the initial state of the entire fixture), try to place the retaining ring 5 on the step surface 202 of the jaw 2. If the retaining ring 5 cannot clamp on the step surface 202 of the jaw 2, the jaw 2 needs to slide toward the outer wall of the chassis 1, and the adjusting tightening bolt 3 can be screwed to make the jaw 2 move a certain distance toward the outer wall of the chassis 1. Compared with the fixture shown in CN217801028U, this processing fixture has stronger adaptability and clamping performance for non-standard circular retaining rings (such as retaining rings with protruding ears on the outer wall).
