Description

Technical Field

[0001] This utility model belongs to the technical field of automated polishing equipment, and in particular relates to an automated polishing fixture for workpieces that can be quickly changed. Background Technology

[0002] Polishing fixtures are key auxiliary devices used to securely hold workpieces during polishing operations. Their design directly affects polishing efficiency, surface quality, and operational safety.

[0003] Because existing tooling often uses threaded clamps to secure workpieces, it requires many turns of screwing to complete the fixation, resulting in a very slow installation process.

[0004] To address these issues, we propose an automated workpiece grinding fixture with rapid changeover capability. Utility Model Content

[0005] The purpose of this invention is to solve the problem of very slow installation and operation speed, and to propose an automated workpiece grinding fixture that allows for quick changeover.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated workpiece grinding fixture with quick changeover capability includes a frame. An operating table is fixedly connected to the upper part of the frame. A magnet is slidably inserted inside the operating table. A foot pedal is movably fitted under the magnet, and the rear of the foot pedal is fixedly connected to the operating table. A steel workpiece is placed on the operating table, and the magnet attracts and holds the workpiece. Stepping on the foot pedal downwards exerts a downward force on the magnet, reducing the magnetic force and allowing the workpiece to be removed. The magnetic force is controlled by stepping, facilitating quick workpiece changeover.

[0008] Preferably, a return spring is provided between the operating table and the foot pedal. The upper end of the return spring is fixedly connected to the operating table, and the lower end of the return spring is fixedly connected to the foot pedal. The spring force of the return spring acts upward on the foot pedal, causing the foot pedal to return to its original position, facilitating the re-fixing of the workpiece.

[0009] Preferably, the operating table includes a table body, the lower end of which is fixedly connected to a guide sleeve and a bearing bracket, and the rear part of the table body is fixedly connected to the machine frame.

[0010] Preferably, the magnet block includes a magnet ring, with a threaded post inserted inside the magnet ring. A nut is threaded onto the threaded post and secured within the magnet ring. A washer ring is placed at the lower end of the magnet ring. The magnet ring slides within the platform and guide sleeve. A sleeve frame is fixedly connected to the lower end of the threaded post. Stepping down on the foot pedal acts downwards on the sleeve frame, which in turn acts downwards on the threaded post, which in turn acts downwards on the nut, which in turn acts downwards on the magnet ring. Placing the workpiece on the operating table and then releasing the foot pedal allows internal gas to slowly escape using the clearance between the magnet ring and the platform / guide sleeve. This clearance helps buffer the impact force and protects the magnet ring.

[0011] Preferably, the footrest includes a frame, a footrest frame is fixedly connected to the lower end of the frame, and a rotating shaft is fixedly connected to the rear end of the frame. The rotating shaft is rotatably mounted in a bearing bracket, and the frame moves through the sleeve frame. The lower end of a return spring is fixedly connected to the upper end of the frame. When a foot is inserted into the footrest frame and pressed down, the footrest frame acts downwards on the frame, increasing the downward force on the sleeve frame using leverage, making it convenient to pull the magnet downwards with the foot.

[0012] Preferably, the stepping frame further includes reinforcing rods, which are fixedly connected to the frame body. The reinforcing rods increase the stability of the frame's external shape.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Place the steel workpiece on the operating table, use the magnet to hold the workpiece in place, step down on the foot pedal to make the foot pedal act downwards, and through the foot pedal, the magnet acts downwards and away from the workpiece, reducing the attraction force on the workpiece, and remove the workpiece. The attraction force can be controlled by stepping down, which facilitates quick workpiece replacement.

[0015] 2. Step down on the foot pedal, which acts downward on the sleeve frame, which in turn acts downward on the threaded post, which in turn acts downward on the nut, which in turn acts downward on the magnetic ring. Place the workpiece on the operating table, then release the foot pedal. The allowance between the magnetic ring and the table body and guide sleeve allows the internal gas to slowly leak out. The allowance helps to buffer the impact force and protect the magnetic ring.

[0016] 3. Insert your foot into the footrest and step down on the footrest. The footrest acts downward on the frame, using leverage to increase the downward force on the frame, making it easier to pull the magnet down with your foot. Attached Figure Description

[0024] like Figure 1 As shown, a return spring 5 is provided between the operating platform 2 and the foot pedal 4. The upper end of the return spring 5 is fixedly connected to the operating platform 2, and the lower end of the return spring 5 is fixedly connected to the foot pedal 4. The elastic force of the return spring 5 acts upward on the foot pedal 4, causing the foot pedal 4 to return to its original position.

[0025] like Figure 1 and 2 As shown, the operating platform 2 includes a platform body 21. A guide sleeve 22 and a bearing bracket 23 are fixedly connected to the lower end of the platform body 21, and the rear part of the platform body 21 is fixedly connected to the frame 1. The guide sleeve 22 guides the magnet block 3 to rise and fall, and the bearing bracket 23 guides the foot pedal 4 to swing.

[0026] like Figure 1 and 3As shown, the magnet block 3 includes a magnet ring 31, with a threaded post 32 inserted inside the magnet ring 31.
