Description

Technical Field

[0001] This utility model belongs to the field of grinding disc processing technology, specifically relating to an adjustable tooling for grinding disc processing. Background Technology

[0002] Alloy grinding discs are core components widely used in fiber powder preparation or grinding in industries such as wood-based panels, pharmaceuticals, pulverizing, tobacco, and machinery. They include multi-element alloy grinding discs, high-chromium alloy grinding discs, and nickel hard alloy grinding discs. Alloy grinding discs have a hardness higher than ductile iron and stainless steel, and higher chromium white iron and nickel hard white iron grinding discs have better impact toughness. During the production and processing of alloy steel grinding discs, positioning fixtures are required to position and fix the alloy steel grinding discs for machining.

[0003] For example, CN 218556870 U discloses an adjustable positioning fixture for grinding disc processing, belonging to the field of alloy steel grinding disc processing technology. It includes a bottom cylindrical shell and a fixture table. The upper end of the bottom cylindrical shell is rotatably connected to a rotating cover via a bearing ring, and a rotating mechanism is provided within the bottom cylindrical shell. One end of the rotating mechanism is fixedly connected to the inner wall of the rotating cover. The fixture table is fixedly connected to the upper side of the rotating cover. The fixture table has a hollow structure and a clamping mechanism within it. Two symmetrically arranged openings are opened on the upper side of the fixture table, and two symmetrically arranged clamping blocks are fixedly connected to the two openings at both ends of the clamping mechanism. In this utility model, the clamping mechanism allows for adjustment of the distance between the two clamping blocks, clamping and fixing the grinding disc. This facilitates positioning and clamping grinding discs of different diameters and lengths. The rotating mechanism allows the grinding disc on the fixture table to rotate, improving processing convenience.

[0004] While the above-mentioned cases can fix grinding discs of different diameters and lengths in actual use, they have many components, making operation cumbersome and costly, which makes it difficult to meet current needs. Therefore, this utility model provides an adjustable tooling for grinding disc processing. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable tooling for grinding disc processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tooling for grinding disc processing, comprising a base frame, two fixing plates fixedly connected to the top of the base frame, and a fixing member for fixing the grinding disc fixedly connected to the front of the fixing plates by bolts, the fixing member comprising a mounting column bolted to the fixing plate, four elastic limiting members equidistantly arranged in an annular shape on the outer side of the top of the mounting column, a guide groove provided on the front of the fixing member, and a limiting block slidably connected inside the guide groove.

[0007] In a preferred embodiment, a sliding block is slidably connected inside the guide groove, and sliding grooves adapted to the sliding block are provided on both sides of the inner cavity of the guide groove. A screw is fixedly connected to the front of the sliding block, and the limiting block is threadedly connected to the outside of the screw.

[0008] In a preferred embodiment, both sides of the sliding block are fixedly connected to the two ends of the guide groove by conical springs, and the length of the conical spring closer to the fixing member is less than the length of the other conical spring.

[0009] In a preferred embodiment, each of the elastic limiting members includes a first limiting part fixedly connected to the top of the mounting post, a second limiting part at the bottom of the first limiting part, and two third limiting parts on both sides of the bottom of the second limiting part.

[0010] In a preferred embodiment, the connection between the first limiting part and the second limiting part, and the connection between the second limiting part and the third limiting part, are provided with abutting protrusions. The abutting protrusions are triangular in shape, and the ends of the abutting protrusions are arc-shaped.

[0011] In a preferred embodiment, the third limiting part is fixedly connected to the mounting post with a first reset member, the second limiting part is fixedly connected to the mounting post with a second reset member, the first limiting part is fixedly connected to the mounting post with a third reset member, the first reset member has the smallest thickness, the second reset member has a deformation cavity inside, the third reset member has the largest thickness, and the top of the third reset member has a deformation groove.

[0012] In a preferred embodiment, the fastener is an integral injection-molded structure, and both ends of the base frame are provided with mounting grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This adjustable tooling for grinding disc processing can fix the grinding disc simply by aligning the mounting hole inside the grinding disc with the fixing part and pressing it. It is not only very simple and convenient, but also requires fewer parts, which reduces the cost of the equipment and increases its market competitiveness.

[0015] This adjustable fixture for grinding discs features a limiting part as a crucial component of the fixing mechanism. This allows the fixture to fit snugly against the edge of the grinding disc, preventing it from shifting or falling off during processing. The limiting part also possesses a degree of elasticity, allowing for appropriate deformation based on the actual bore diameter of the grinding disc, thus ensuring a secure fixation. A key feature of the limiting part is the abutment protrusion, which is triangular in shape with an arc-shaped end. This design not only enhances the friction between the limiting part and the grinding disc but also allows the fixture to better adapt to subtle changes in the grinding disc surface. When the grinding disc is placed on the fixing mechanism, the abutment protrusion fits tightly against the disc surface, preventing slippage or displacement. Furthermore, the arc-shaped design of the abutment protrusion reduces wear between the fixture and the grinding disc, extending the fixture's service life.

[0016] This adjustable fixture for grinding disc processing has a reset component to ensure that the limiting part can quickly return to its original state after being subjected to external force. The reset component can maintain the stability of the limiting part and prevent it from deforming or being damaged by external force. At the same time, the reset component also has a certain degree of elasticity and can be adjusted appropriately according to the actual hole diameter of the grinding disc, thereby ensuring good adaptability of the fixture to grinding discs with different hole diameters.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-3 This utility model provides an adjustable tooling for grinding disc processing, including a base frame 1. Two fixing plates 2 are fixedly connected to the top of the base frame 1. Fixing members 3 for fixing grinding discs are fixedly connected to the front of the fixing plates 2 by bolts. The fixing members 3 include mounting posts 301 that are bolted to the fixing plates 2. The fixing members 3 are integrally injection molded structures. Both ends of the base frame 1 are provided with mounting grooves 101. The base frame 1 can be installed through the mounting grooves 101. After installation, the fixing members 3 are installed inside the fixing plates 2 by bolts, thus completing the assembly of the equipment and making it ready for use.

[0024] In this embodiment, four elastic limiting members 302 are provided at equal intervals in a ring around the top of the mounting post 301. Each elastic limiting member 302 includes a first limiting part 3021 fixedly connected to the top of the mounting post 301, a second limiting part 3022 at the bottom end of the first limiting part 3021, and two third limiting parts 3023 on both sides of the bottom of the second limiting part 3022. The connection between the first limiting part 3021 and the second limiting part 3022 and the second limiting part 3022 are connected. Each connection point with the third limiting part 3023 is provided with an abutment protrusion 3024. The abutment protrusion 3024 is triangular in shape, and its end is arc-shaped. The third limiting part 3023 is fixedly connected to the mounting post 301 with a first reset member 303. The second limiting part 3022 is fixedly connected to the mounting post 301 with a second reset member 304. The first limiting part 3021 is fixedly connected to the mounting post 301 with a third reset member 305. The first reset member 303... The second reset member 304 has the smallest thickness and a deformation cavity inside. The third reset member 305 has the largest thickness and a deformation groove at the top of the mounting post 301. The four elastic limiting members 302 are distributed in a ring at equal intervals. When the grinding disc needs to be installed on the tooling, the mounting hole of the grinding disc is first aligned with the mounting post 301. As the grinding disc is gradually pressed down, the edge of the grinding disc will first contact the abutment protrusion 3024 of the third limiting part 3023. Due to the arc design of the abutment protrusion 3024, it can adapt well to the shape of the edge of the grinding disc and increase the friction to prevent the grinding disc from sliding during installation. As the grinding disc continues to be pressed down, the third limiting part 3023 will be subjected to downward pressure and deformed through the first reset member 303. At the same time, the second limiting part 3022 and the first limiting part 3021 will also be subjected to pressure and deformed through the second reset member 304 and the third reset member 305. These deformations allow the elastic limiting member 302 to fit tightly against the edge of the grinding disc, thereby achieving a stable fixation of the grinding disc. When the grinding disc is fully installed in place, the external force disappears, and the first reset member 303, the second reset member 304, and the third reset member 305 will quickly return to their initial state, causing the third limiting part 3023, the second limiting part 3022, and the first limiting part 3021 to also return to their initial positions. In this way, the elastic limiting member 302 tightly wraps around the edge of the grinding disc, achieving a stable fixation of the grinding disc.

[0025] By designing reset components of different thicknesses and structures (first reset component 303, second reset component 304, and third reset component 305), and abutment protrusions 3024 with arc-shaped ends, this fixture can well adapt to grinding discs with different hole diameters and edge shapes, achieving stable fixation. Due to the design of the elastic limiting component 302, when the grinding disc is installed on the fixture, it can closely fit the edge of the grinding disc, and achieve stable fixation of the grinding disc through the elastic force of the reset component. This helps to prevent the grinding disc from shaking or falling off during processing, improving processing accuracy and safety. The design of this fixture makes the installation and removal of the grinding disc very simple and quick. Users only need to align the mounting hole of the grinding disc with the mounting post 301 and press down gently to complete the installation, without the need for additional tools or equipment.

[0026] In this embodiment, a guide groove 201 is provided on the front side of the fixing member 3. A limiting block 203 is slidably connected inside the guide groove 201, and a sliding block 202 is slidably connected inside the guide groove 201. Sliding grooves adapted to the sliding block 202 are provided on both sides of the inner cavity of the guide groove 201. A screw 4 is fixedly connected to the front side of the sliding block 202, and the limiting block 203 is threadedly connected to the outside of the screw 4. Both sides of the sliding block 202 are fixedly connected to the two ends of the guide groove 201 by conical springs 204. The length of the conical spring 204 closer to the fixing member 3 is less than the length of the other conical spring 204. On the front side of the fixing member 3, the design of the guide groove 201 provides a sliding track for the limiting block 203 and the sliding block 202. When it is necessary to adjust the position of the limiting block 203 to accommodate grinding discs of different sizes, it can... During the sliding process of the sliding block 202, the conical springs 204 on both sides will exert elastic force. The conical spring 204 closer to the fixing part 3 has a relatively large elastic force due to its shorter length, which can provide stronger support for the sliding block 202. The other conical spring 204 has a relatively small elastic force due to its longer length, which allows the sliding block 202 to produce a larger displacement when subjected to external force. This design makes the position adjustment of the limiting block 203 more flexible and can adapt to grinding discs of different sizes. After the limiting block 203 is adjusted to the appropriate position, the user can place the grinding disc on the fixing part 3 and fix the grinding disc by the limiting block 203. Since the position of the limiting block 203 can be adjusted according to the size of the grinding disc, this fixture can achieve stable fixation of grinding discs of different sizes.

[0027] By designing a combined structure of guide groove 201, limit block 203 and sliding block 202, this tooling can achieve height adaptability to grinding discs of different sizes. Users only need to adjust the position of limit block 203 to meet the fixing requirements of different grinding discs.

[0028] The working principle and usage process of this utility model are as follows: First, the base frame 1 can be installed through the mounting groove 101. After installation, the fixing part 3 is installed inside the fixing plate 2 by bolts, thus completing the assembly of the equipment and making it ready for use. When it is necessary to install the grinding disc onto the tooling, first align the mounting hole of the grinding disc with the mounting post 301. As the grinding disc is gradually pressed down, the edge of the grinding disc will first contact the abutting protrusion 3024 of the third limiting part 3023. Due to the arc design of the abutting protrusion 3024, it can adapt well to the shape of the edge of the grinding disc, while increasing the friction and preventing the grinding disc from sliding during installation. As the grinding disc continues to be pressed down, the third limiting part 3023 will be subjected to downward pressure and deformed through the first reset part 303. At the same time, the second limiting part 3022 and the first limiting part 3021 will also be subjected to pressure accordingly and deformed through the second reset part 304 and the third reset part 305. These deformations allow the elastic limiting member 302 to tightly conform to the edge of the grinding disc, thus achieving a stable fixation of the grinding disc. Once the grinding disc is fully installed and the external force disappears, the first reset member 303, the second reset member 304, and the third reset member 305 will quickly return to their initial state, causing the third limiting part 3023, the second limiting part 3022, and the first limiting part 3021 to also return to their initial positions. In this way, the elastic limiting member 302 tightly wraps around the edge of the grinding disc, achieving a stable fixation. When it is necessary to adjust the position of the limiting block 203 to accommodate grinding discs of different sizes, the sliding block 202 can be slid. During the sliding process of the sliding block 202, the sides... The conical spring 204 will exert its elastic force. The conical spring 204 closer to the fixing part 3 has a relatively large elastic force due to its shorter length, which can provide stronger support for the sliding block 202. The other conical spring 204 has a relatively small elastic force due to its longer length, which allows the sliding block 202 to produce a larger displacement when subjected to external force. This design makes the position adjustment of the limiting block 203 more flexible and can adapt to grinding discs of different sizes. After the limiting block 203 is adjusted to the appropriate position, the grinding disc is fixed by the limiting block 203. Since the position of the limiting block 203 can be adjusted according to the size of the grinding disc, this fixture can achieve a stable fixation of grinding discs of different sizes.
