Description

Technical Field

[0001] This invention relates to the field of surface grinding mill technology, and more particularly to a surface grinding mill fixture. Background Technology

[0002] In the field of modern precision machining, surface grinders are widely used as key equipment in the grinding of thin-film products in industries such as electronics and optics. With the trend of product refinement and thinning, the performance requirements for surface grinder fixtures are becoming increasingly stringent.

[0003] Existing surface grinding machine fixtures typically use a single material to create the fixed profile structure of the product. During actual processing, due to the extremely thin thickness of the product, friction and pressure generated during machining easily lead to rapid wear of the tooth pitch on the fixed profile. Related research data indicates that the service life of such fixtures is generally only 4-5 hours. This short lifespan necessitates frequent fixture replacements, significantly increasing both production time and material costs. Summary of the Invention

[0004] In order to solve the technical problems existing in the background art, the present invention proposes a surface grinding machine fixture.

[0005] The present invention provides a surface grinding machine fixture, comprising: a fixture outer ring, a fixture inner ring, and a mounting component for connecting the machine base. The fixture inner ring is adapted to be mounted on the fixture outer ring, and the fixture inner ring and the fixture outer ring are located on the same first surface. The mounting component is disposed between the fixture inner ring and the fixture outer ring to limit the fixture inner ring during the rotation of the fixture outer ring, thereby keeping the fixture inner ring on the first surface.

[0006] Preferably, the outer ring of the fixture is a steel sheet, the inner ring of the fixture is a fiberboard, the steel sheet is provided with an installation area, and the fiberboard is adapted to be installed in the installation area.

[0007] Preferably, the mounting assembly includes multiple positioning protrusions arranged in a ring array on the steel sheet, and the fiberboard has multiple positioning grooves, with the multiple positioning protrusions being fitted and stored in the multiple positioning grooves one by one.

[0008] Preferably, the multiple positioning protrusions are located on the inner wall of the steel sheet and extend into the installation area, and the multiple positioning protrusions are located on the first surface.

[0009] Preferably, the mounting area on the steel sheet is a recessed cavity with a width of 20-30mm. The fiberboard is completely embedded in the recessed cavity, and a product positioning area is provided on the fiberboard.

[0010] Preferably, the outer ring of the steel sheet is provided with a fixed gap tooth pitch, which matches the tooth pitch of the machine tool and is used to drive the fixture to rotate.

[0011] Preferably, the gap between the steel sheet and the fiberboard is 0.15-0.2mm, the thickness of the steel sheet is 0.2-0.5mm, the thickness of the fiberboard is the same as that of the steel sheet, the difference between the height of the positioning protrusion and the depth of the positioning groove is less than 0.1mm, the contact surface of the positioning protrusion has a 60-degree inclination angle, and the radius of the rounded corner at the end of the protrusion is 20mm.

[0012] This invention proposes a surface grinding machine fixture with the following advantages: The outer ring of the fixture uses a tempered steel sheet, whose high wear resistance significantly increases the lifespan of the fixed tooth pitch from the original 4 hours to 4 days, greatly improving the fixture's durability, reducing the frequency of fixture replacement, and lowering production costs. The inner ring fiberboard can be replaced individually after wear, avoiding abnormal situations such as machine breakage and product fragmentation caused by overall fixture wear, effectively reducing the product defect rate and improving machine processing efficiency. The mounting components, through the cooperation of positioning protrusions and positioning grooves, achieve quick installation and stable connection between the inner and outer rings of the fixture. When the fiberboard needs to be replaced due to wear, the operation is convenient and quick, without significantly affecting production efficiency, greatly improving the flexibility and economy of fixture use. The structural design of the tempered steel sheet and fiberboard, and their cooperation, enables precise product positioning. Combined with the special angle and rounded corner design of the positioning protrusion, it ensures the stability of the product during processing, reduces product defects caused by inaccurate positioning, and improves product processing quality.

[0015] Figure 3 This is a structural diagram of the fiberboard of a surface grinding machine fixture proposed in this invention. Detailed Implementation

[0016] refer to Figure 1-3 This invention proposes a fixture for a surface grinder, comprising: an outer ring for connecting to the machine base, an inner ring for the fixture, and a mounting assembly. The inner ring is fitted onto the outer ring, and both the inner and outer rings are located on a first surface. The mounting assembly is disposed between the inner and outer rings, and its function is to limit the movement of the inner ring during the rotation of the outer ring, ensuring that the inner ring remains on the first surface and guaranteeing the stability of the fixture operation.

[0017] Furthermore, the outer ring of the fixture is made of stainless steel sheet 1, and the inner ring is made of fiberboard 4. Stainless steel sheet 1 has good wear resistance, effectively extending the service life of the outer ring of the fixture; fiberboard 4 is relatively soft, making it easy to replace after wear, and avoids the chipping problem that may occur with pure stainless steel sheet. The stainless steel sheet 1 has an installation area 3, on which the fiberboard 4 is fitted and installed to achieve a stable combination.

[0018] The mounting components include multiple positioning protrusions 2 arranged in a ring array on the steel sheet 1, and multiple positioning grooves 5 on the fiberboard 4. During installation, the multiple positioning protrusions 2 can be fitted and stored one-to-one in the multiple positioning grooves 5. This structural design not only facilitates the rapid installation of the inner and outer rings of the fixture, but also effectively prevents the fiberboard 4 from shifting relative to the steel sheet 1 during fixture operation, ensuring the stability of the overall fixture structure.

[0019] Multiple positioning protrusions 2 are located on the inner wall of the steel sheet 1 and extend into the installation area 3, and are all on the first surface, ensuring that the positioning protrusions 2 can accurately cooperate with the positioning grooves 5 to effectively limit the fiberboard 4.

[0020] The mounting area 3 on the steel sheet 1 is an inwardly recessed cavity with a width of 20-30mm. This size ensures that the fiberboard 4 is completely embedded in the cavity, allowing the fiberboard 4 to fit tightly against the steel sheet 1. The fiberboard 4 has a product positioning area 6 for placing the product to be processed. The precise positioning of the product is achieved through the cooperation of the steel sheet 1 and the fiberboard 4.

[0021] The outer ring of the steel sheet 1 is provided with a fixed clearance tooth pitch, which is precisely matched with the tooth pitch of the machine tool. When the machine tool is running, the two mesh with each other, thereby driving the fixture to rotate and ensuring that the fixture can run smoothly on the machine tool to achieve effective processing of the product.

[0022] The gap between the outer and inner rings of the fixture is controlled at 0.15-0.2mm, ensuring smooth installation of the fiberboard 4 within the steel plate 1 while preventing wobbling during operation due to excessive gap. The thickness of the steel plate 1 is 0.2-0.5mm, and the thickness of the fiberboard 4 is consistent with that of the steel plate 1 to ensure uniform overall fixture thickness and balance during processing. The height difference between the positioning protrusion 2 and the depth difference between the positioning groove 5 is less than 0.1mm, ensuring a tight fit between the positioning protrusion 2 and the positioning groove 5 and enhancing the positioning effect. The contact surface of the positioning protrusion 2 is designed with a 60-degree inclination angle, and the radius of the protrusion end is 20mm. This design facilitates product positioning and placement while reducing damage to the product.

[0023] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and the inventive concept of the present invention, should be covered within the scope of protection of the present invention.
