Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically a four-corner positioning tooling for processing alumina ceramic sheets. Background Technology

[0002] Alumina ceramics are ceramic materials primarily composed of alumina (Al₂O₃) and are used in thick-film integrated circuits. Alumina ceramics possess good electrical conductivity, mechanical strength, and high-temperature resistance. It is important to note that ultrasonic cleaning is required. Alumina ceramics are a widely used ceramic material, and due to their superior properties, their applications in modern society are becoming increasingly widespread, meeting both everyday and specialized needs.

[0003] The existing Chinese utility model patent with announcement number CN207788706U discloses a four-corner positioning fixture for processing alumina ceramic sheets. This utility model includes a drying chamber with a drying slope. A hot air blower is installed in the cavity structure at the bottom of the drying slope. Stirring blades are installed in the drying chamber. A feed inlet is opened on the vertical surface of the drying chamber, and a discharge outlet is opened on the bottom surface of the drying chamber. Corn kernels come out from the feed inlet and slowly slide down the drying slope. The hot air blower heats the corn kernels under the action of the induced draft fan, and the stirring blades stir them. Multiple stirring blades process the corn kernels in sequence, resulting in good drying effect. Hot air heating and mechanical stirring avoid direct heating and drying of corn kernels, which can make the corn kernels dry evenly. The corn kernels that have been processed once can be repeatedly dried through a conveyor belt and a receiving box to ensure that the corn kernel drying effect meets the standards.

[0004] The existing alumina ceramic sheet processing method is not convenient for positioning and clamping the alumina ceramic sheet around its perimeter, nor is it convenient for clamping and rotating circular alumina ceramic sheets, thus affecting the practical effect of the equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of existing technologies that make it inconvenient to clamp alumina ceramic sheets around their perimeter and rotate circular alumina ceramic sheets, and to provide a four-corner positioning fixture for processing alumina ceramic sheets.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A four-corner positioning fixture for processing alumina ceramic sheets includes:

[0008] A support block has four motorized rotating shafts movably connected around its perimeter. A connecting plate is fixedly installed on one side of each motorized rotating shaft. A connecting groove, shaped like a "C," is fixedly installed on the top side of one side of the connecting plate. A silicone groove, also shaped like a "C," is fixedly installed inside the connecting groove. A support frame, also shaped like a "C," is fixedly installed on the bottom side of one side of the connecting plate. A motor, also shaped like a "C," is fixedly installed at the bottom of the support frame. A rotating rod, also shaped like a "C," is fixedly installed on the top of the motor. A rubber tube, shaped like a "C," is fixedly installed on the outside of the rotating rod.

[0009] In a preferred embodiment, a base plate is fixedly installed at the bottom of the support block, and four bases are fixedly installed around the bottom of the base plate. The bases are structures used to support the bottom.

[0010] In a preferred embodiment, an electric turntable is fixedly installed on the top of the support block, and a support plate is movably connected to the top of the electric turntable, the support plate being a support structure.

[0011] In a preferred embodiment, an anti-slip block is fixedly installed on the top of the support plate, the anti-slip block being a structure for preventing slippage.

[0012] In a preferred embodiment, four support grooves are fixedly installed around the support block, and a fixing block is fixedly installed at the bottom of the support groove. The fixing block is a structure used for fixing.

[0013] In a preferred embodiment, the fixing block is triangular in shape, and a telescopic column is fixedly installed on one side of the inner side of the support groove. The telescopic column is a structure for telescopic movement.

[0014] In a preferred embodiment, a spring is fixedly installed on one side of the telescopic column, and a connecting rod is fixedly installed on one side of the spring. The connecting rod is a structure used for connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This four-corner positioning fixture for processing alumina ceramic sheets uses a silicone groove inside the connecting slot on the top of one side of the connecting plate to clamp and fix the alumina ceramic sheet around its perimeter. The silicone groove also acts as a buffer. When a circular alumina ceramic sheet needs to be clamped, the connecting plate can be rotated by an electric rotating shaft, allowing the silicone tube to clamp the circular alumina ceramic sheet around its perimeter. The motor can also rotate the rotating rod, allowing the circular alumina ceramic sheet clamped by the silicone tube to rotate, thus improving the practicality of this four-corner positioning fixture for processing alumina ceramic sheets.

[0017] 2. This four-corner positioning fixture for processing alumina ceramic sheets uses the retraction of telescopic columns to move four connecting rods from the periphery to the center, thereby positioning and clamping the alumina ceramic sheets around their perimeter. Springs provide a buffering effect, improving the practicality of the fixture. An electric turntable allows for rotational adjustment of the alumina ceramic sheet on the top of the support plate, and anti-slip blocks provide a non-slip effect, further enhancing the practicality of the fixture.

[0024] Combined with appendix Figure 1-4 In this embodiment, a four-corner positioning fixture for processing alumina ceramic sheets includes: a support block 1, a base plate 11 fixedly installed at the bottom of the support block 1, four bases 12 fixedly installed around the bottom of the base plate 11, an electric turntable 13 fixedly installed at the top of the support block 1, a support plate 14 movably connected to the top of the electric turntable 13, and an anti-slip block 15 fixedly installed at the top of the support plate 14.

[0025] Specifically, the base plate 11 can support the support block 1, the four bases 12 around the bottom of the base plate 11 can support the bottom of the four corner positioning fixture for processing the alumina ceramic sheet, and the electric turntable 13 can drive the support plate 14.

[0026] Four support grooves 2 are fixedly installed around the support block 1. A fixing block 21 is fixedly installed at the bottom of the support groove 2. The fixing block 21 is triangular in shape. A telescopic column 22 is fixedly installed on one side of the inside of the support groove 2. A spring 23 is fixedly installed on one side of the telescopic column 22. A connecting rod 24 is fixedly installed on one side of the spring 23.

[0027] Specifically, the fixing block 21 can provide auxiliary support for the support groove 2, and the extension and retraction of the telescopic column 22 inside the support groove 2 can push the connecting rod 24 to move. The spring 23 can provide a buffering effect and avoid the problem of excessive clamping force.

[0028] Support block 1, with four electric rotating shafts 3 movably connected around its perimeter. A connecting plate 31 is fixedly installed on one side of each electric rotating shaft 3. A connecting groove 32 is fixedly installed on the top side of one side of the connecting plate 31. The connecting groove 32 is in the shape of a "C". A silicone groove 33 is fixedly installed inside the connecting groove 32. The silicone groove 33 is in the shape of a "C". A support frame 34 is fixedly installed on the bottom side of one side of the connecting plate 31. The support frame 34 is in the shape of a "C". A motor 35 is fixedly installed at the bottom of the support frame 34. A rotating rod 36 is fixedly installed on the top of the motor 35. A rubber tube 37 is fixedly installed on the outside of the rotating rod 36. The side of the rubber tube 37 is in the shape of a "C".

[0029] Specifically, the electric rotating shaft 3 can drive the connecting plate 31 to rotate, the silicone groove 33 inside the connecting groove 32 can clamp the alumina ceramic sheet around its perimeter, and the operation of the motor 35 can drive the rotating rod 36 to rotate, thereby causing the rubber tube 37 to rotate the clamped circular alumina ceramic sheet.

[0030] Working Principle: First, the four-corner positioning fixture for processing alumina ceramic sheets is placed in the designated position. The four bases 12 around the bottom of the base plate 11 provide support around the bottom of the fixture, improving its practicality. The support plate 14 supports the alumina ceramic sheet, and the anti-slip slider 15 on the top of the support plate 14 provides an anti-slip effect, further enhancing the practicality of the fixture. The operation of the electric turntable 13 rotates the alumina ceramic sheet on top of the support plate 14, improving its practicality and convenience. The fixing block 21 supports the support groove 2. The extension and retraction of the telescopic column 22 inside the support groove 2 pushes the connecting rod 24 to move simultaneously to the sides or center. The spring 23 provides a buffering effect. This allows the connecting plate 31 to move, and the silicone groove 33 inside the connecting groove 32 can be used to position and clamp the alumina ceramic sheet around its perimeter, improving the practicality and stability of the four-corner positioning fixture for processing alumina ceramic sheets. When it is necessary to clamp the perimeter of a circular alumina ceramic sheet, the operation of the electric rotating shaft 3 can drive the connecting plate 31 to rotate 180 degrees, so that the perimeter of the circular alumina ceramic sheet can be clamped and fixed through the rubber tube 37. At the same time, the rubber tube 37 and the silicone groove 33 can play a buffering role, improving the practicality of the four-corner positioning fixture for processing alumina ceramic sheets. The operation of the motor 35 can drive the rotating rod 36 to rotate, so that the rubber tube 37 can rotate. At the same time, in conjunction with the rotation of the electric turntable 13, the clamped circular alumina ceramic sheet can be rotated, improving the practicality and convenience of the four-corner positioning fixture for processing alumina ceramic sheets.
