Description

Technical Field

[0001] This utility model belongs to the field of machining technology, specifically relating to a fixture for machining ceramic rods. Background Technology

[0002] Ceramic rods, as a common ceramic material, are widely used in industries such as electronics, machinery, and optics, especially in electronic components, insulating materials, and precision instruments. The processing of ceramic rods is quite challenging, mainly due to the brittleness and high hardness of ceramic materials, as well as the precise shape requirements. Therefore, specially designed fixtures are needed to ensure stability and accuracy during the processing.

[0003] Patent publication number CN202910723U discloses a fixture for processing slender ceramic rods, including a cylindrical fixture body. The fixture body has holes at both the upper and lower ends. One end of the fixture body has a clamping hole for holding the ceramic rod, and the other end of the fixture body has a small hole for abutting against the ejector pin of the tailstock of an external cylindrical grinding machine. The small hole fits tightly with the ejector pin, and the clamping hole fits with the ceramic rod with an interference fit. The main advantages of this patent are: convenient processing and the ability to ensure the straightness and roundness of the processed slender ceramic rod.

[0004] However, the existing fixtures used for processing slender ceramic rods have the following problems: when the existing fixtures clamp and fix the ceramic rod workpieces, the clamping force is too large or too small, which causes the workpieces to be damaged or the clamping is unstable. Therefore, we propose a fixture for processing ceramic rods. Utility Model Content

[0005] The purpose of this utility model is to provide a fixture for processing ceramic rods, which can solve the problem that existing processing fixtures in the related technology cause workpiece damage and unstable clamping when clamping and fixing ceramic rod workpieces due to excessive or insufficient clamping force.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A fixture for processing ceramic rods includes a support platform, a worktable fixedly connected to the top of the support platform, a precision positioning device provided on the top of the support platform, the precision positioning device including a base column, the bottom of the base column being rotatably connected to the top of the support platform, a threaded rod fixedly connected to the top of the base column, a threaded slip ring threadedly connected to the threaded surface of the threaded rod, a safety clamping assembly provided on the outer wall of the threaded slip ring, and a force-binding block fixedly connected to the moving end of the safety clamping assembly.

[0008] The safety clamping assembly includes multiple slide grooves, which are formed on the top of the worktable. A transverse slider is slidably connected to the inner wall of each slide groove. A hinge rod is hinged to the bottom of each transverse slider, and the end of the hinge rod away from the transverse slider is hinged to the outer wall of a threaded slip ring. A vertical plate is fixedly connected to the top of the transverse slider. A sliding column is slidably connected through the side of the vertical plate. The side of a force-combining block is fixedly connected to the end of the sliding column away from the vertical plate. A compression spring is provided between the force-combining block and the vertical plate. A placement plate is fixedly connected to the top of the worktable. The sliding column serves as the moving end of the safety clamping assembly.

[0009] The bottom of the force-binding block is in contact with the top of the workbench, and the multiple force-binding blocks are evenly spaced.

[0010] The outer wall of the hinge rod is provided with a gap from the bottom of the workbench, and the side of the force-binding block near the placement plate is provided with a rough surface.

[0011] A splash protection device is provided on the side of the vertical plate away from the force-binding block. The splash protection device includes an elastic telescopic rod. The fixed end of the elastic telescopic rod is fixedly connected to the side of the vertical plate away from the force-binding block. A protective arc plate is fixedly connected to the telescopic end of the elastic telescopic rod. A triangular top plate is fixedly connected to the top of the protective arc plate. A fastening pad is fixedly connected to the outer wall of the protective arc plate.

[0012] The protective arc plate is made of a sound-absorbing and highly durable material, and the side of the fastening pad is in contact with the side of the triangular top plate.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention, through the setting of a precise positioning device, enables the base column, threaded rod, threaded slip ring, sliding groove, transverse slider, hinge rod, vertical plate, sliding column, force-binding block, compression spring, and placement plate to cooperate. The force-binding block stops moving due to the reverse force, but the vertical plate continues to move towards the placement plate. At this time, the vertical plate applies a force to the compression spring, so that the force-binding block can apply a specific clamping force to the ceramic rod workpiece. This avoids the workpiece being damaged due to excessive or insufficient clamping force when the fixture is clamping and fixing the ceramic rod workpiece.

[0015] This utility model, through the setting of a splash-proof protection device, enables the elastic telescopic rod, protective arc plate, triangular top plate, and fastening pad to cooperate. The protective arc plate slides towards the placement plate, causing the triangular top plate to slide towards the placement plate. The triangular top plate slides towards the placement plate, causing the fastening pad to slide towards the placement plate, so that the fastening pads are pressed tightly together. This prevents the flying chips and noise from processing from causing injury to the workers when the device processes the workpiece. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5 As shown, a fixture for processing ceramic rods includes a support platform 1, a worktable 2 fixedly connected to the top of the support platform 1, a precision positioning device 3 provided on the top of the support platform 1, the precision positioning device 3 including a base column 31, the bottom of the base column 31 being rotatably connected to the top of the support platform 1, a threaded rod 32 fixedly connected to the top of the base column 31, a threaded slip ring 33 threadedly connected to the threaded surface of the threaded rod 32, a safety clamping assembly provided on the outer wall of the threaded slip ring 33, and a force-binding block 39 fixedly connected to the moving end of the safety clamping assembly, the force-binding block 39 being provided to ensure the basic clamping conditions of the device.

[0025] The safety clamping assembly includes multiple slides 34, which are formed on the top of the worktable 2. A transverse slider 35 is slidably connected to the inner wall of each slide 34. A hinge rod 36 is hinged to the bottom of the transverse slider 35. The end of the hinge rod 36 away from the transverse slider 35 is hinged to the outer wall of the threaded slip ring 33. A vertical plate 37 is fixedly connected to the top of the transverse slider 35. A sliding column 38 is slidably connected through the side of the vertical plate 37. A force-combining block 39 is fixedly connected to the side of the sliding column 38 away from the vertical plate 37. A compression spring 310 is provided between the force-combining block 39 and the vertical plate 37. A placement plate 311 is fixedly connected to the top of the worktable 2. The sliding column 38 is set as the moving end of the safety clamping assembly. The elastic force of the compression spring 310 can be set according to the force on the clamped workpiece.

[0026] The bottom of the force-jointing block 39 contacts the top of the worktable 2. The multiple force-jointing blocks 39 are evenly spaced, which ensures the stability of the workpiece during clamping.

[0027] The outer wall of the hinge rod 36 is provided with a gap between it and the bottom of the worktable 2. The side of the force-jointing block 39 near the placement plate 311 is provided with a rough surface. The rough surface can prevent the workpiece from loosening when it is clamped.

[0028] Based on the above structure, the ceramic rod workpiece is placed on the placement tray 311. Then, the operator manually rotates the base column 31. The rotation of the base column 31 causes the threaded rod 32 to rotate. The rotation of the threaded rod 32 causes the threaded slip ring 33 to move upwards under the constraint of the transverse slider 35 and the hinge rod 36. The downward movement of the threaded slip ring 33 causes the hinge rod 36 to rotate. The rotation of the hinge rod 36 causes the transverse slider 35 to slide towards the placement tray 311. The sliding of the transverse slider 35 towards the placement tray 311 causes the vertical plate 37 to slide towards the placement tray 311. The sliding of the vertical plate 37 towards the placement tray 311 causes the sliding column 38 to slide towards the placement tray 311. Sliding in the direction of 11, the sliding column 38 slides towards the placement plate 311, causing the force-acting block 39 to slide towards the placement plate 311. When the force-acting block 39 slides and contacts the ceramic rod workpiece, the force-acting block 39 is subjected to a reverse force and stops moving, but the vertical plate 37 still moves towards the placement plate 311. At this time, the vertical plate 37 applies a force to the compression spring 310, so that the force-acting block 39 can apply a specific clamping force to the ceramic rod workpiece, avoiding the situation where the workpiece is damaged due to excessive or insufficient clamping force when the fixture clamps and fixes the ceramic rod workpiece.

[0029] like Figure 1-5As shown, a splash protection device 4 is provided on the side of the vertical plate 37 away from the force-binding block 39. The splash protection device 4 includes an elastic telescopic rod 41. The fixed end of the elastic telescopic rod 41 is fixedly connected to the side of the vertical plate 37 away from the force-binding block 39. The telescopic end of the elastic telescopic rod 41 is fixedly connected to a protective arc plate 42. A triangular top plate 43 is fixedly connected to the top of the protective arc plate 42. A fastening pad 44 is fixedly connected to the outer wall of the protective arc plate 42. The fastening pad 44 can isolate the internal dust and flying debris from the outside.

[0030] The protective arc plate 42 is made of a sound-absorbing and highly durable material. The side of the fastening pad 44 contacts the side of the triangular top plate 43. The necessary contact ensures the smooth operation of the device.

[0031] According to the above structure, the vertical plate 37 slides towards the placement plate 311, causing the elastic telescopic rod 41 to slide towards the placement plate 311. The elastic telescopic rod 41 slides towards the placement plate 311, causing the protective arc plate 42 to slide towards the placement plate 311. The protective arc plate 42 slides towards the placement plate 311, causing the triangular top plate 43 to slide towards the placement plate 311. The triangular top plate 43 slides towards the placement plate 311, causing the fastening pad 44 to slide towards the placement plate 311, so that the fastening pads 44 are pressed together, so that when the device processes the workpiece, it avoids the flying chips and noise from processing from causing injury to the workers.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
