Description

Technical Field

[0001] This utility model relates to the field of cemented carbide processing technology, and in particular to a polishing clamping device for alloy strips. Background Technology

[0002] In the performance evaluation of cemented carbide, it is necessary to observe the porosity and metallographic structure of the cemented carbide. To facilitate observation, the observation surface of the cemented carbide is usually ground and polished first. During grinding and polishing, the operator holds the sample by hand and polishes it. Due to the imbalance of downward force applied by the operator during polishing, the end face after grinding and polishing is beveled, and it is also easy to burn fingers. At the same time, the polishing disc is a high-speed rotating device, so manual operation also poses a great safety risk. Utility Model Content

[0003] This utility model provides an alloy strip polishing clamping device to overcome the shortcomings of the prior art and solve the safety and unevenness problems that exist in existing polishing and grinding processes, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A polishing clamping device for alloy strips is mounted on a polishing machine. The polishing machine includes a machine base, an internal motor, and a polishing disc connected to the motor's output shaft. The device includes a pair of vertical rods mounted on the machine base, with pressure blocks fitted on the vertical rods. A spring is fitted at the lower end of each pressure block and is fitted onto the vertical rod. At least one pair of horizontal rods are positioned between the pressure blocks, with a horizontal sliding block fitted on each horizontal rod. A guide block is fitted at the lower end of each horizontal sliding block, and a movable block is fitted on each guide block. A guide groove is formed at the upper end of each movable block, and the guide block passes through the guide groove. A pair of clamping devices are threaded onto the movable block. The screw, with its inner end acting on the outer wall of the guide block, has multiple placement slots at its lower end. A magnetic attraction device is installed within the movable block. During polishing, this device attracts the alloy strip placed in the slots, securing it in place. Simultaneously, pressing down on the movable block during grinding ensures the lower wall of the alloy strip adheres tightly to the polishing disc. A spring mechanism allows the alloy strip to disengage from the polishing disc after polishing is complete. Furthermore, the movement of the transverse block allows for polishing of the alloy strip in two symmetrical directions via two positions on the polishing disc.

[0006] Furthermore, the magnetic attraction device is equipped with an electromagnet and a battery. When the battery supplies power to the electromagnet, the electromagnet generates a magnetic field, which is used to attract the alloy strip. The use of an electromagnet facilitates switch control.

[0007] Furthermore, the placement slots are arranged in parallel to each other to facilitate the placement and positioning of multiple alloy strips.

[0008] Furthermore, the intersecting arrangement of the placement slots allows for improved polishing results by performing perpendicular grinding and polishing operations on the alloy strips.

[0009] Furthermore, baffles are provided at both ends of the placement groove. The baffles limit the alloy strip to prevent it from moving out of the placement groove during polishing.

[0010] Furthermore, the height of the baffle is less than the depth of the placement groove to facilitate the removal of the alloy strip.

[0011] Furthermore, the guide block and the guide groove are matched in shape and structure, and the guide block is dovetail-shaped or T-shaped, which facilitates the adjustment of the position of the movable block.

[0012] Furthermore, the magnetic attraction device includes a placement box located within the movable block. Multiple magnets are placed inside the placement box, with a one-to-one correspondence between the magnets and the placement slots. The length direction of each magnet is parallel to the length direction of its corresponding placement slot, and the magnet is positioned directly above its corresponding placement slot. One end of the placement box has a rotating shaft, and an eccentric rod is eccentrically positioned on the inner end of the rotating shaft. The magnet is placed on the eccentric rod. This design increases the distance between the magnet and the alloy strip by rotating the eccentric rod, thereby reducing the magnet's attraction to the alloy strip and facilitating the removal of the alloy strip.

[0013] The advantages of the above technical solution are:

[0014] This invention can fix the alloy strip during grinding and polishing, and also ensure the grinding and polishing effect. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0016] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0017] Figure 2 The three-dimensional structure of the transverse block is shown. Figure 1 .

[0018] Figure 3 The three-dimensional structure of the transverse block is shown. Figure 2 . Detailed Implementation

[0019] like Figures 1-3As shown, an alloy strip polishing clamping device is mounted on a polishing machine. The polishing machine includes a machine base 1, inside which is a motor. A polishing disc 11 is connected to the output shaft of the motor. The device includes a pair of vertical rods 2 mounted on the machine base 1. A pressure block 20 is sleeved on the vertical rod 2. A spring 21 is provided at the lower end of the pressure block 20 and is sleeved on the vertical rod 2. At least one pair of horizontal rods 22 are provided between the pressure blocks 20. A horizontal moving block 3 is sleeved on the horizontal rod 22. A guide block 30 is provided at the lower end of the horizontal moving block 3. A movable block 31 is sleeved on the guide block 30. A guide groove 32 is opened at the upper end of the movable block 31. The guide block 30 passes through the guide groove 32. The shape and structure of the guide block 30 and the guide groove 32 are matched, and the guide block 30 is dovetail-shaped or T-shaped. A pair of tightening screws are threaded onto the movable block 31. The inner ends of the tightening screws act on the outer wall of the guide block 30. Multiple placement slots 35 are provided at the lower end of the movable block 31. The placement slots 35 are arranged either parallel to each other or intersecting each other. Baffles 36 are provided at both ends of each placement slot 35. The height of the baffles 36 is less than the depth of the placement slot 35. A magnetic attraction device 34 is provided inside the movable block 31. During polishing, the magnetic attraction device is used to attract the alloy strip 4 placed in the placement slot 35.

[0020] In this embodiment, during operation, the operator places the alloy strip 4 in the placement groove 35, and then uses the magnetic attraction device 34 to adsorb and fix the alloy strip 4.

[0021] Then start the motor so that it drives the polishing disc 11 to rotate.

[0022] During grinding and polishing, the operator moves the transverse block 3 to a position and then presses down on the movable block 31, causing the movable block 31 and its lower end alloy strip 4 to move downwards, so that the lower wall of the alloy strip 4 contacts the polishing disc 11, and then performs the grinding and polishing operation. After this process has been repeated for a period of time, the transverse block 3 is moved to the other end of the crossbar 22, and grinding and polishing are performed again.

[0023] After polishing is completed, the force is removed, and the alloy strip 4 will then move upward under the action of the spring 21, thus releasing the magnetic attraction device 34 from the alloy strip 4 and removing it.

[0024] Optionally, the magnetic attraction device 34 is equipped with an electromagnet and a battery. When the battery supplies power to the electromagnet, the electromagnet generates a magnetic field for the attraction of the alloy strip 4. When attraction is in progress, the start and stop of the electromagnet's attraction force can be controlled by the power switch.

[0025] Optionally, the magnetic attraction device 34 includes a placement box located within the movable block 31. Multiple magnets are placed inside the placement box, with a one-to-one correspondence between the magnets and the placement slots 35. The length direction of the magnet is parallel to the length direction of its corresponding placement slot 35, and the magnet is located directly above its corresponding placement slot 35. One end of the placement box is provided with a rotating shaft, and an eccentric rod is eccentrically provided on the inner end of the rotating shaft. The magnet is placed on the eccentric rod. When the attraction is canceled, the magnet can be moved away from the alloy strip by rotating the eccentric rod, thereby reducing the magnet's attraction to the alloy strip, and then the alloy strip 4 can be removed.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
