[0033] On the one hand, if Figure 1 and Figure 2 As shown, an embodiment of the present application provides a grinding and polishing fixture 100, including a mounting seat 110, a clamping assembly 120 and a locking member.
[0034] The mounting seat 110 has a mounting surface 111, and the mounting surface 111 is provided with a mounting hole 112. The clamping assembly 120 is mounted in the mounting hole 112. One end of the clamping assembly 120 close to the mounting surface 111 includes a first clamping portion 1211 and a second clamping portion 1221 spaced apart from each other. The first clamping portion 1211 and the second clamping portion 1221 are configured to be controllably close to and away from each other, so as to cooperate with each other to clamp the workpiece.
[0035] The locking member is connected to the mounting base 110 , and one end of the locking member can extend into the mounting hole 112 and abut against the clamping assembly 120 to lock and fix the clamping assembly 120 relative to the mounting base 110 .
[0036] It should be noted that, in this embodiment, the workpiece to be processed is a bar. In other embodiments, the workpiece to be processed may also be other products, which are not limited here. The following description will be made by taking a bar as an example.
[0037] Using the above-mentioned grinding and polishing jig, first separate the first clamping part 1211 and the second clamping part 1221, put the bar bar between the first clamping part 1211 and the second clamping part 1221, and then bring the first clamping part 1211 and the second clamping part 1221 close to each other to clamp the bar bar. Next, put the clamping assembly 120 into the mounting hole 112 and lock it with the locking member to ensure that at least part of the bar bar protrudes from the mounting surface 111. Finally, press the bar bar onto the polishing pad with the grinding and polishing jig for grinding and polishing. Since the first clamping part 1211 and the second clamping part 1221 can move close to and away from each other, bars of different sizes can be clamped, which effectively improves the versatility of the grinding and polishing jig.
[0038] In one embodiment, the mounting surface 111 is provided with a plurality of mounting holes 112, and the polishing fixture includes a plurality of clamping components 120 and a plurality of locking members, each clamping component 120 is mounted in a corresponding mounting hole 112, and the plurality of locking members and the plurality of clamping components 120 are arranged in a one-to-one correspondence, that is, each clamping component 120 is locked and fixed by a corresponding locking member. In this way, a plurality of bar bars can be clamped by a plurality of clamping components 120, so that the polishing fixture can polish a plurality of bar bars at the same time, thereby improving processing efficiency. Figure 2 In the illustrated embodiment, there are four mounting holes 112, which are evenly spaced along the circumference of the mounting seat 110. In this way, during the grinding and polishing process, the bar protruding from the mounting surface 111 contacts the polishing pad, and the four bar bars can provide more stable support, thereby ensuring the stability of the mounting seat 110 during the grinding and polishing process.
[0039] In one embodiment, the mounting hole 112 also penetrates the side of the mounting seat 110 away from the mounting surface 111, that is, the mounting hole 112 penetrates the two opposite sides of the mounting seat 110. In this way, the clamping assembly 120 can be placed into the mounting hole 112 from the other outer side to ensure that the bar bar protrudes from the mounting surface 111, and then the clamping assembly 120 is locked by the locking member. In addition, the bar bar may need to remain connected to the optical fiber during the polishing process, and the optical fiber can also extend from the side of the mounting seat 110 away from the mounting surface 111 through the mounting hole 112, thereby facilitating the placement of the optical fiber.
[0040] Please also see Figure 3In one embodiment, the clamping assembly 120 includes a first clamping member 121 and a second clamping member 122, which are arranged at intervals and can be controlled to approach and move away from each other. The end of the first clamping member 121 close to the mounting surface 111 has the above-mentioned first clamping portion 1211, and the end of the second clamping member 122 close to the mounting surface 111 has the above-mentioned second clamping portion 1221. In this way, when the first clamping member 121 and the second clamping member 122 approach each other, the first clamping portion 1211 and the second clamping portion 1221 will synchronously approach and move away from each other.
[0041] Furthermore, the clamping assembly 120 also includes an adjustment module, which is connected to the first clamping member 121 and the second clamping member 122, and the adjustment module can adjust the distance between the first clamping member 121 and the second clamping member 122, thereby adjusting the distance between the first clamping portion 1211 and the second clamping portion 1221, so that the first clamping member 121 and the second clamping member 122 can clamp bar strips of different sizes.
[0042] Optionally, the adjustment module may also be a stud with two sections of threads, the two sections of threads are located at both ends of the stud, and the directions of the two sections of threads are opposite, and the first clamping member 121 and the second clamping member 122 are threadedly connected to the two ends of the stud, so that they are close to or away from each other during the rotation of the stud. In addition, in order to improve the stability of the adjustment, multiple studs can be set for synchronous adjustment, which is not limited here.
[0043] In other embodiments, the adjustment module may also include a bolt and a top screw, one end of the bolt passes through the first clamp 121 and is threadedly connected to the second clamp 122, the other end of the bolt abuts against the side of the first clamp 121 away from the second clamp 122, the top screw is threadedly connected to the first clamp 121, and one end of the top screw abuts against the second clamp 122. In this way, the distance between the first clamp 121 and the second clamp 122 can be adjusted by the bolt and the top screw. Similarly, in order to improve the stability of the adjustment, multiple bolts and multiple top screws can be set for adjustment.
[0044] In one embodiment, the first clamping member 121 and the second clamping member 122 are arranged at intervals along the width direction of the mounting hole 112, and the locking member extends into the mounting hole 112 along the width direction of the mounting hole 112 and abuts against the first clamping member 121 or the second clamping member 122. Specifically, the locking member abuts against the side of the second clamping member 122 that is away from the first clamping member 121. In other embodiments, the clamping assembly 120 may further include a mounting block, the first clamping member 121 and the second clamping member 122 are arranged at intervals on a side of the mounting block close to the mounting surface 111, and at least one of the first clamping member 121 and the second clamping member 122 can move back and forth, so that the first clamping member 121 and the second clamping member 122 are close to and away from each other, and the locking member abuts against the mounting block.
[0045] In one embodiment, at least one of the first clamping member 121 and the second clamping member 122 abuts against two inner walls of the mounting hole 112 that are opposite to each other along the length direction thereof. In this way, the first clamping member 121 and the second clamping member 122 are fixed in the length direction of the mounting hole 112 by two inner walls of the mounting hole 112, and in the width direction of the mounting hole 112 by one inner wall of the mounting hole 112 and the locking member, so that the clamping assembly 120 can be fixed relative to the mounting seat 110, thereby preventing the clamping assembly 120 from shaking, thereby ensuring the polishing effect.
[0046] See also Figure 4 and Figure 5 In one embodiment, the first clamping portion 1211 is provided with a clamping groove 1212, and the clamping groove 1212 includes a first clamping surface 1213 and a bottom surface 1214 that are connected to each other and set at an angle, and the second clamping portion 1221 has a second clamping surface 1222, and the first clamping surface 1213 and the second clamping surface 1222 are opposite to each other and parallel to each other, so as to clamp and fix the bar bar in the process of approaching each other. At the same time, when placing the bar bar, the bar bar can be placed in the clamping groove 1212 first, and then the bar bar can be clamped and fixed. It can be understood that in other embodiments, the clamping groove 1212 can be provided on the second clamping portion 1221, and the clamping surface can be provided on the first clamping portion 1211, which is not limited here.
[0047] Furthermore, the first clamping surface 1213 and the second clamping surface 1222 are tilted relative to the height direction of the mounting hole 112, that is, tilted relative to the vertical direction, so that the bar bar is tilted relative to the vertical direction after clamping, meeting the required polishing angle. Figure 1 In the illustrated embodiment, the first clamping surface 1213 and the second clamping surface 1222 are inclined at an angle of 15° relative to the vertical direction to meet the bar polishing angle of 75°.
[0048] See also Figure 1 and Figure 2In one embodiment, the polishing fixture further includes a counterweight 130, which is detachably connected to the mounting seat 110 and is located on a side of the mounting seat 110 away from the mounting surface 111, so as to increase the counterweight during the polishing process, increase the polishing pressure, and improve the polishing effect. In addition, as described above, the mounting hole 112 passes through the side of the mounting seat 110 away from the mounting surface 111, and the optical fiber can extend through the mounting hole 112, and the optical fiber extending from the mounting hole 112 can be fixed on the counterweight 130.
[0049] In one embodiment, the mounting seat 110 is further provided with a locking hole 113, one end of the locking hole 113 is connected to the mounting hole 112, and the other end passes through the mounting seat 110, and the locking member extends into the mounting hole 112 through the locking hole 113 and abuts against the clamping assembly 120.
