Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically a magnetic polishing fixture. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface.

[0003] The surface of a tap can be made smooth by grinding and polishing. However, in the current grinding process, the tap is usually clamped and fixed in the middle. Since the clamping part cannot contact the grinding material during the grinding process, the clamping part needs to be ground and polished again after the initial grinding and polishing. This makes the polishing process complicated. In addition, the existing clamping method does not allow for convenient replacement of the tap.

[0004] Therefore, a magnetic polishing fixture is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a magnetic polishing fixture that can solve the problems of incomplete polishing and easy replacement of existing devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a support frame and a connecting rod disposed at the lower end of the support frame, wherein there are a plurality of connecting rods, a connecting sleeve is inserted into the lower end of the connecting rod, and a strong magnetic block is disposed between the connecting sleeve and the connecting rod;

[0007] The lower end face of the connecting rod is provided with a connector, the connector is magnetically connected to the strong magnetic block, the strong magnetic block is magnetically connected to the inside of the connecting sleeve, and the connector is inserted into the inside of the connecting sleeve;

[0008] A tap is provided below the connecting sleeve. The tap is inserted into the inside of the connecting sleeve and is magnetically connected to the lower surface of the strong magnetic block.

[0009] Preferably, the upper half of the connecting sleeve is provided with a placement groove, and the lower half of the connecting sleeve is provided with a insertion groove, wherein the placement groove and the insertion groove are connected.

[0010] Preferably, the placement slot has a square structure, the strong magnetic block has the same structure as the placement slot, and the connector has the same structure as the strong magnetic block.

[0011] Preferably, the strong magnetic block has a through-hole insertion conical groove, the insertion conical groove has a conical structure, and the upper half of the tap body has a chamfered insertion joint with a conical structure.

[0012] Preferably, the connector passes through the connector groove, and the connector is inserted into the connector tapered groove.

[0013] Preferably, the strong magnetic block is an integral square structure, the upper half of the tap is ground to form a square-structured connector, and the insertion groove has the same structure as the connector.

[0014] Preferably, the connector passes through the connector slot, and the upper surface of the connector is magnetically connected to the lower surface of the strong magnet.

[0015] Compared with the prior art, the present invention provides a magnetic polishing fixture, which has the following advantages:

[0016] 1. Based on the magnetic attraction of the strong magnetic block itself, the connector, strong magnetic block, connecting sleeve, and tap can be positioned and connected. Based on the magnetic attraction of the connection, the tap and connecting sleeve can be easily adjusted and replaced, improving the convenience of replacement.

[0017] 2. By magnetically connecting the connector and the taper groove, the upper part of the tap can be magnetically fixed, thus achieving the effect of fixing the tap as a whole. Compared with the traditional method of clamping the entire tap, the tap can be ground and shaped in one go, preventing the clamping part from being unable to be effectively ground.

[0018] 3. By setting the shapes of the insertion conical groove and the insertion connector to fit each other in a conical shape, the connection area between the insertion connector and the insertion conical groove is increased, ensuring the stability of the magnetic connection of the tap body.

[0019] 4. By setting the connector and the strong magnet to the same square structure, the contact area between the connector and the strong magnet is maximized, ensuring that the magnetic connection is stable and reliable when the connector is used in different configurations.

[0025] 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.

[0026] Example:

[0027] Please see Figure 1 - Figure 4 A magnetic polishing fixture in this embodiment includes a support frame 1 and a connecting rod 2 disposed at the lower end of the support frame 1. There are several connecting rods 2, and a connecting sleeve 5 is inserted into the lower end of the connecting rod 2. A strong magnetic block 4 is disposed between the connecting sleeve 5 and the connecting rod 2.

[0028] A connector 3 is provided on the lower end face of the connecting rod 2. The connector 3 is magnetically connected to the strong magnetic block 4. The strong magnetic block 4 is magnetically connected to the inside of the connecting sleeve 5. The connector 3 is inserted into the inside of the connecting sleeve 5.

[0029] A tap 6 is provided below the connecting sleeve 5. The tap 6 is inserted into the inside of the connecting sleeve 5 and is magnetically connected to the lower surface of the strong magnetic block 4.

[0030] Among them, by installing a drive source on the upper end of the support frame 1, the device is equipped with the ability to drive the rotation of a single connecting rod 2, rotate the upper part as a whole, and support the height movement of it. This driving method is a well-known technology in the field, so it is not described in detail in this embodiment. At the same time, the stability of grinding the tap 6 is ensured by the support of the grinding material below.

[0031] Based on the magnetic attraction of the strong magnetic block 4 itself, the connector 3, the strong magnetic block 4, the connecting sleeve 5, and the tap 6 can be positioned and connected. Based on the magnetic attraction of their connection, the tap 6 and the connecting sleeve 5 can be easily adjusted and replaced, improving the convenience of their replacement.

[0032] The upper part of the connecting sleeve 5 is provided with a placement groove 501, and the lower part of the connecting sleeve 5 is provided with a insertion groove 502. The placement groove 501 and the insertion groove 502 are connected.

[0033] The placement slot 501 has a square structure, the strong magnetic block 4 has the same structure as the placement slot 501, and the connector 3 has the same structure as the strong magnetic block 4.

[0034] The strong magnetic block 4 has a through-hole insertion cone groove 401, which has a cone-shaped structure. The upper half of the tap 6 has a chamfered insertion connector 601 with a cone-shaped structure.

[0035] The connector 601 passes through the connector groove 502, and the connector 601 is inserted into the connector cone groove 401;

[0036] The connecting sleeve 5 has a placement groove 501 and a insertion groove 502 inside, which provides a placement space for the strong magnetic block 4 and a guiding support for the tap 6 and the insertion connector 601, so that the insertion connector 601 and the insertion tapered groove 401 are inserted and positioned. By setting the shape of the insertion tapered groove 401 and the insertion connector 601 to be a tapered shape that fits each other, the connection area between the insertion connector 601 and the insertion tapered groove 401 is increased, ensuring the stability of the magnetic connection of the tap 6.

[0037] By magnetically connecting the connector 601 and the connector groove 401, the upper half of the tap 6 is magnetically fixed, which can achieve the effect of fixing the tap 6 as a whole. Compared with the traditional method of clamping the tap 6 as a whole, the tap 6 can be ground and shaped in one go, preventing the clamping part from being unable to be effectively ground.

[0038] The strong magnetic block 4 has an integral square structure. The upper half of the tap 6 is ground into a square structure of the connector 601. The connector groove 502 has the same structure as the connector 601.

[0039] The connector 601 passes through the connector slot 502, and the upper surface of the connector 601 is magnetically connected to the lower surface of the strong magnet 4.

[0040] By setting the connector 601 and the strong magnet 4 to the same square structure, the contact area between the connector 601 and the strong magnet 4 is maximized when the tap 6 is inserted into the connecting sleeve 5, ensuring that the magnetic connection is stable and reliable when the connector 601 is used in different configurations.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods.
