Description

Technical Field

[0001] The utility model relates to the field of lens processing, in particular to a clamp component for processing rod lenses. Background Art

[0002] Rod mirror, as a special optical element, is widely used in various optical systems and equipment. Its shape is similar to a slender cylinder, and the surface needs to achieve extremely high smoothness and flatness to meet the requirements of optical performance. Therefore, in the production process of rod mirror, grinding (including fine grinding and polishing) is a crucial link.

[0003] Traditional grinding equipment for polishing rod mirrors mainly consists of two parts: one is the pressure head used to press the rod mirror, and the other is the fixture used to place and fix the rod mirror. This fixture is usually designed with a fixed socket whose inner diameter matches the outer diameter of the rod mirror to ensure that the rod mirror can be stably placed in the fixture.

[0004] During operation, the operator needs to first insert the rod mirror into the socket of the fixture and ensure that it is placed firmly. Then, the grinding equipment presses one end of the rod mirror against the workbench through the pressure head to grind it. In this process, the pressure head is usually equipped with polishing materials or abrasives, which remove tiny protrusions and defects by friction with the surface of the rod mirror, thereby gradually improving its surface finish.

[0005] However, this traditional grinding equipment has a significant problem: alignment accuracy. Since the fixture and the pressure head need to be precisely aligned to ensure that the rod mirror is not subjected to uneven pressure or misalignment during the grinding process, this is often a challenging task in actual operation. If the alignment is inaccurate, the two are easily misaligned during the pressing process, which will not only affect the grinding effect, but may also cause scratches, indentations and other damages on the surface of the rod mirror, and may even make the entire rod mirror scrapped.

[0006] Therefore, improving the alignment accuracy and stability of the grinding equipment is one of the urgent problems to be solved in the current rod mirror production process. Summary of the invention

[0007] In order to solve the above problems, the utility model discloses a clamp assembly for processing a rod mirror.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions: a fixture assembly for processing a rod mirror, comprising an outer sleeve connected to a pressure head of a grinding device, and an inner sleeve used for aligning with the outer sleeve, wherein the inner sleeve and the outer sleeve are detachably connected and matched; the inner diameter of the inner sleeve matches the rod mirror to be processed, and a first buffer washer is provided at the bottom end of the outer sleeve;

[0009] When the inner sleeve is placed in the outer sleeve, the outer end portion of the inner sleeve is exposed from the outer sleeve, and the rod mirror placed in the inner sleeve can extend to the outside of the inner sleeve.

[0010] In the above solution, a flange is arranged at the outer end of the inner sleeve, and the outer diameter of the flange is larger than that of the outer sleeve.

[0011] In the above solution, a second buffer washer 201 is disposed at the top end of the outer sleeve 101 , and the second buffer washer 201 is located below the flange 202 .

[0012] In the above solution, a plurality of guide strips are arranged at the bottom end of the inner sleeve along its axial direction.

[0013] In the above solution, the protruding thickness of the guide strip is gradually reduced from top to bottom.

[0014] In the above solution, an outer edge is protruding from the outer periphery of the bottom end of the outer sleeve, and the outer edge is fitted together with the pressure head of the grinding equipment.

[0015] The solution of the embodiment of the present application directly integrates the outer sleeve on the pressure head of the grinding equipment. This integrated design not only simplifies the structure of the clamp assembly, but also improves its overall stability. When installing and placing the rod mirror, the operator can easily achieve accurate alignment of the rod mirror and the pressure head by simply switching the inner sleeve and the outer sleeve.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0021] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention. As used in the specification and appended claims of the present invention, the singular expressions "a", "an", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0022] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0023] Example 1: See Figure 1-3 A fixture assembly for processing a rod mirror comprises an outer sleeve 101 connected to a pressure head 100 of a grinding device, and an inner sleeve 200 for aligning with the outer sleeve 101, wherein the inner sleeve 200 and the outer sleeve 101 are detachably connected and matched; specifically, the outer diameter of the inner sleeve 200 can be the same as the inner diameter of the outer sleeve 101, such as Figure 2 As shown, during connection, one end of the inner sleeve 200 is inserted into the outer sleeve 101 , and the rod mirror 300 is inserted into the inner sleeve 200 .

[0024] The inner diameter of the inner sleeve 200 matches the rod mirror to be processed, and the bottom end of the outer sleeve 101 is provided with a first buffer washer 102;

[0025] When the inner sleeve 200 is placed in the outer sleeve 101 , the outer end portion of the inner sleeve 200 is exposed from the outer sleeve 101 , and the rod mirror placed in the inner sleeve 200 can extend to the outside of the inner sleeve 200 .

[0026] A second buffer washer 201 is disposed at the top end of the outer sleeve 101 , and the second buffer washer 201 is located below the flange 202 .

[0027] The first buffer gasket 102 is located at the bottom end of the outer sleeve 101. It is made of a highly elastic material (such as silicone) and has a certain thickness and softness to provide a buffering effect when the pressure head presses the rod mirror to prevent the rod mirror from breaking due to excessive pressure. The second buffer gasket 201 at the top of the outer sleeve 101 is located on the lower side of the flange 202 of the inner sleeve 200, and can play a buffering role for the inner sleeve 200 as a whole.

[0028] In this embodiment, the outer sleeve 101 is directly integrated on the pressure head 100 of the grinding device. This integrated design not only simplifies the structure of the fixture assembly, but also improves its overall stability. When installing and placing the rod mirror, the operator only needs to switch and cooperate with the inner sleeve 200 and the outer sleeve 101 to easily achieve accurate alignment of the rod mirror and the pressure head 100.

[0029] In addition, in order to adapt to different sizes of rod mirrors, multiple inner sleeves 200 with different inner diameters can be designed. The operator can select a suitable inner sleeve according to the actual size of the rod mirror to ensure the stability and accuracy of the rod mirror during the grinding process. This flexible and changeable design not only improves the versatility of the outer sleeve 101, but also greatly reduces the production cost and the time for changing the fixture, further improving the production efficiency.

[0030] Example 2: See Figure 1-3 The outer end of the inner sleeve 200 is provided with a flange 202, and the outer diameter of the flange 202 is larger than the outer sleeve 101. The flange 202 is located at the outer end of the inner sleeve 200, and its outer diameter is slightly larger than the inner diameter of the outer sleeve 101, forming a certain protruding step, so as to facilitate the removal of the inner sleeve 200 after grinding.

[0031] Example 3: Figure 4 As shown, the bottom end of the inner sleeve 200 is provided with a plurality of guide strips 203 along its axial direction. Specifically, the protruding thickness of the guide strips 203 is gradually reduced from top to bottom. The guide strips 203 are axially arranged along the bottom end of the inner sleeve 200, and the number can be determined as required (generally 3-6). The protruding thickness thereof is gradually reduced from top to bottom, forming a certain inclined surface. This design can guide the rod mirror to be smoothly inserted into the inner sleeve.

[0032] Example 4: See Figure 1-3 The outer rim 103 is convexly provided on the outer circumference of the bottom end of the outer sleeve 101, and the outer rim 103 is fitted together with the pressure head 100 of the grinding equipment. The outer rim 103 is located on the outer circumference of the bottom end of the outer sleeve 101, and its shape matches the pressure head 100 of the grinding equipment. The outer rim is made of hard material and has a certain thickness and strength, so as to provide a certain support effect for the outer sleeve 101, making it more stable during operation.

[0033] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
