Description

Technical Field

[0001] This utility model relates to the field of grinding disc processing and positioning technology, specifically to an improved grinding disc processing and positioning device. Background Technology

[0002] The millstone is a core grinding tool in traditional agriculture and modern industry. Its core component consists of two circular stone discs stacked on top of each other. The lower disc is fixed as a base, while the upper disc rotates around an axis to achieve the grinding function. Its material is mainly granite to ensure wear resistance and stability.

[0003] In the grinding wheel machining process, accurate positioning is crucial to ensuring the dimensional accuracy, shape accuracy, and surface quality of the grinding wheel. However, existing positioning devices often require operators to spend a lot of time adjusting and fixing the grinding wheel when clamping it. The operation process is complicated, which reduces the processing efficiency. Moreover, the repeatability of each clamping is poor, making it difficult to ensure the consistency of grinding wheel processing in different batches. Therefore, there is an urgent need for an improved grinding wheel machining positioning device to overcome the above defects. Utility Model Content

[0004] The purpose of this utility model is to provide an improved grinding disc processing positioning device, which has the advantages of good positioning effect and convenient clamping and fixing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved grinding disc machining positioning device, comprising a worktable, a base, a fixed clamping assembly, a rotational lifting adjustment assembly, and an inner clamping assembly. The base is fixedly installed at the bottom of the worktable. The fixed clamping assemblies are all located on both sides of the top of the worktable. The inner clamping assembly is located at the center of the top of the worktable. The rotational lifting adjustment assembly is located at the center of the bottom of the worktable. The fixed clamping assembly includes a first positioning arc-shaped block, a first sliding groove, a first motor, a first slider, and a first threaded rod. The rotational lifting adjustment assembly includes a positioning column, a first gear, a second gear, a second motor, a positioning seat, a clamping rod, and an electric push rod. The inner clamping assembly includes a fixed block, a third motor, a second sliding groove, a second positioning arc-shaped block, a connecting rod, a second slider, and a second threaded rod.

[0006] Furthermore, a positioning column is rotatably connected to the center of the workbench via a bearing. A first gear is fixedly installed at the bottom of the positioning column, and a second gear is meshed with the surface of the first gear through teeth. A second motor is fixedly installed at the top of the second gear.

[0007] Furthermore, the top of the second motor is fixedly connected to the bottom of the workbench, and a first sliding groove is provided on both sides of the top of the workbench. A first slider is slidably connected inside the first sliding groove, and a first positioning arc block is fixedly installed on the top of the first slider.

[0008] Furthermore, the first slider is internally connected to a first threaded rod via a threaded connection, and a first motor is fixedly installed on both sides of the worktable. The output shaft of the first motor passes through the inner cavity of the first slide groove and is fixedly connected to the side of the first threaded rod that is relatively far away from it. A locking rod is fixedly installed on the top of the positioning column.

[0009] Furthermore, a positioning seat is slidably connected to the surface of the clamping rod, an electric push rod is fixedly installed at the top of the inner cavity of the positioning seat, the bottom of the electric push rod is fixedly connected to the top of the clamping rod, and a fixing block is fixedly installed at the top of the positioning seat.

[0010] Furthermore, a third motor is fixedly installed on both the left and right sides of the fixing block, and a second sliding groove is opened on both the front and rear sides of the fixing block. A second slider is slidably connected inside the second sliding groove, and a connecting rod is fixedly installed on the side of the second slider that is relatively far away from it.

[0011] Furthermore, a second positioning arc-shaped block is fixedly installed on the side of the connecting rod that is relatively far away from the other side. The second sliding block is connected to a second threaded rod through a threaded connection. The side of the third motor that is relatively close to the other side passes through the inner cavity of the second slide groove and is fixedly connected to the side of the second threaded rod that is relatively far away from the other side.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention increases the stability of the overall device by setting a base, fixes the outer side of the grinding disc by setting a fixing clamping assembly, fixes the inner ring of the grinding disc by setting an inner clamping assembly, and adjusts the height and rotation angle of the inner clamping assembly by setting a rotation lifting adjustment assembly. During fixing, according to the height of the grinding disc, the electric push rod is opened, which drives the positioning seat to move upward, thereby adjusting the height of the fixing block. After adjustment, the third motor is opened, which drives the second threaded rod to rotate, causing the second slider to drive the connecting rod and the second positioning arc block to move outward, and the grinding disc is fixed under the action of the second positioning arc block. After fixing, the second motor is turned on, which drives the second gear and the first gear to rotate, causing the positioning column to rotate and thus adjusting the position of the grinding disc. After adjustment, the first motor is turned on, which drives the first threaded rod to rotate, causing the first slider to move the first positioning arc block inward, thereby clamping and fixing the outer side of the grinding disc. This method has the advantages of good positioning effect and convenient clamping and fixing. It solves the problem that existing positioning devices often require operators to spend a lot of time adjusting and fixing when clamping the grinding disc, which is complicated, reduces processing efficiency, and has poor repeatability of each clamping, making it difficult to ensure the consistency of processing of different batches of grinding discs.

The second motor 44 drives the second gear 43 and the first gear 42 to rotate, causing the positioning column 41 to rotate, thereby adjusting the position of the grinding disc. After adjustment, turn on the first motor 33. The first motor 33 drives the first threaded rod 35 to rotate, causing the first slider 34 to move the first positioning arc block 31 inward, thereby clamping and fixing the outer side of the grinding disc. This has the advantages of good positioning effect and convenient clamping and fixing.
