Technical Field

[0001] This utility model relates to the field of magnetic steel processing technology, specifically a magnetic steel grinding positioning device. Background Technology

[0002] Magnet steel is a common name for permanent magnet materials, specifically referring to magnetic materials that can maintain their magnetism for a long time. Permanent magnetism is the most important characteristic of magnet steel.

[0003] Grinding machines are used in the processing of magnets. Existing grinding machines are equipped with jaws to hold cylindrical magnet materials for grinding.

[0004] Conventional grippers use pneumatic or hydraulic power to drive the grippers to hold magnetic materials. This driving method causes the grippers to impact the magnetic materials, and direct impact can damage both the grippers and the magnetic materials.

[0005] In view of this, we propose a magnetic steel grinding positioning device. Utility Model Content

[0008] The two connecting blocks are symmetrically distributed along the transverse axis of the gripping end of the jaws. The two connecting blocks are connected to the jaws through an adjustment structure, which is used to adjust the position of the two connecting blocks relative to the jaws.

[0009] The flexible contact strip is disposed on the inner side of the two connecting blocks and is used to abut against the magnetic steel material.

[0010] Preferably, the flexible contact strip may be made of a wear-resistant material, but not limited to rubber.

[0011] Preferably, the flexible contact strip has multiple grooves on its contact side;

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides two embodiments.

[0035] Example 1

[0036] Please see Figures 1 to 5 A magnetic steel grinding positioning device, wherein the chuck of the grinding machine tool includes a chuck disk 100 and a soft contact bar 400. The chuck disk 100 is installed on the grinding machine tool and is driven by a motor inside the machine tool as a power source. The chuck disk 100 is provided with a cleaver 200, and the clamping end of the cleaver 200 is provided with a connecting block 300.

[0037] Two connecting blocks 300 are symmetrically distributed laterally along the clamping end of the gripper 200. The two connecting blocks 300 are connected to the gripper 200 through an adjusting structure 500, which is used to adjust the position of the two connecting blocks 300 relative to the gripper 200. A soft contact strip 400 is set inside the two connecting blocks 300. The soft contact strip 400 is made of wear-resistant rubber material and is used to abut against the magnetic material. When the soft contact strip 400 contacts the magnetic material, it is a soft contact and has a certain buffering effect.

[0038] The flexible contact strip 400 has multiple grooves 401 on its contact side; the grooves 401 can be arc-shaped. When the flexible contact strip 400 contacts the magnetic material, the grooves 401 provide sufficient space for compression.

[0039] This utility model, by setting a connecting block 300 and a soft contact strip 400, has the advantage that the soft contact strip 400 plays a buffering role when it comes into contact with the magnetic steel material, making it less likely to cause collision damage. It solves the problem that direct impact when the gripper 200 clamps the magnetic steel material may cause damage to both the gripper 200 and the magnetic steel material.

[0040] Example 2

[0041] Please see Figures 2 to 6 A magnetic steel grinding positioning device includes an adjusting structure 500 comprising a fixing block 501 fixedly disposed at the outer end of a gripper 200. A threaded rod 502 with both positive and negative threads passes through the fixing block 501. A rotating handle 504 is fixedly disposed at the end of the threaded rod 502. Two threaded sections of the threaded rod 502 are respectively threadedly connected to moving blocks 505, which are respectively fixedly connected to the outer ends of two connecting blocks 300. Rotating the rotating handle 504 causes the threaded rod 502 to rotate, and the two threaded moving blocks 505 move relative to or away from each other, thereby causing the two connecting blocks 300 to move relative to or away from each other.

[0042] Two limiting rings 503 are fitted onto the threaded screw 502, and the two limiting rings 503 respectively contact and engage with the upper and lower ends of the fixing block 501. The two limiting rings 503 limit the position of the threaded screw 502, so that the connection position between the threaded screw 502 and the fixing block 501 remains stable.

[0043] Two connecting blocks 300 each have a slot 302 on one opposite end of their inner sides. A retaining strip 402 is provided on the mounting side of the flexible contact strip 400, which can be engaged within the two mating slots 302. The retaining strip 402 has a T-shaped cross-section and is adapted to fit the two mating slots 302. When the two connecting blocks 300 move away from each other, the distance between the two slots 302 increases, allowing the retaining strip 402 to be inserted or removed, thus enabling the replacement of the flexible contact strip 400.

[0044] This utility model, by setting a fixing block 501, a positive and negative threaded screw 502, a limiting ring 503, a rotating handle 504, a moving block 505, a slot 302, and a locking strip 402, has the advantages of being able to quickly replace the soft contact strip 400 after it is damaged, and being easy to operate.

[0045] The gripper 200 has a guide groove 201 at its gripping end. Guide blocks 301 are fixedly mounted on the outer sides of the two connecting blocks 300, and the guide blocks 301 can slide within the guide groove 201. The guide block 301 has a trapezoidal cross-section and is adapted to fit the guide groove 201. When the two connecting blocks 300 move relative to each other or away from each other, the guide blocks 301 slide along the guide groove 201, thereby maintaining the stability of the movement of the two connecting blocks 300.

[0046] Working principle: The jaw disc 100 is installed on the grinding machine. The jaws 200 are opened, and the cylindrical magnetic steel material is inserted into the jaw disc 100. Then the jaws 200 clamp the magnetic steel material. The flexible contact bar 400 abuts against the magnetic steel material. The magnetic steel material is clamped by squeezing the magnetic steel material through the flexible contact bar 400. Then the magnetic steel material is processed by the grinding machine.

[0047] To replace the flexible contact strip 400, the operator rotates the handle 504, causing the threaded screw 502 to rotate. The two threaded moving blocks 505 move in opposite directions, causing the two connecting blocks 300 to move in opposite directions. The distance between the two slots 302 increases, allowing the retaining strip 402 to be removed, thus removing the flexible contact strip 400. A new flexible contact strip 400 is then installed, and the new retaining strip 402 is placed between the two slots 302. The handle 504 is rotated in the opposite direction, causing the threaded screw 502 to rotate in the opposite direction. The two moving blocks 505 move relative to each other, causing the two connecting blocks 300 to move relative to each other. After the two slots 302 align, they lock the retaining strip 402, thus fixing the new flexible contact strip 400.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
