Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a magnetic anti-error clamp for irregularly shaped magnets. Background Technology

[0002] In the traditional magnetization process of NdFeB magnets, the workpiece to be magnetized is typically placed manually into the magnetization station inside the magnetizer by holding a jig. However, this method has drawbacks: First, the operator needs to insert the jig into the magnetization station inside the magnetizer, which poses a high risk of mechanical injury; second, it is difficult to precisely control the depth of the jig's insertion into the magnetizer by manual operation. If it is inserted too deeply or too shallowly, it will not reach the accurate magnetization station, resulting in the magnet not being saturated; in addition, the orientation of the jig is easily misidentified during manual placement, which can lead to reverse magnet polarity and the production of defective products.

[0003] Therefore, the applicant intends to propose a magnetizing and error-proofing fixture for irregularly shaped magnets to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fault-preventing clamp for magnetizing irregularly shaped magnets. This clamp ensures that irregularly shaped workpieces arrive at the magnetization station in the correct direction, while the operator does not need to reach into the magnetizer, thus ensuring operational safety.

[0005] To achieve the above objectives, the solution of this utility model is: a magnetizing and error-proofing fixture for irregularly shaped magnets, including a jig plate and a clamp;

[0006] The fixture plate is provided with several contour mounting slots for placing irregularly shaped workpieces to be magnetized, and one end of the fixture plate is provided with a mounting part;

[0007] One end of the clamp is an insertion end that extends into the magnetizer, and the other end of the clamp is a limiting end that restricts the depth of insertion into the magnetizer. The insertion end of the clamp is provided with a clamping part for clamping the fixture plate. An assembly part is provided in the clamping space of the clamping part. The assembly part cooperates with the mounting part of the fixture plate to position the fixture plate and distinguish the orientation of the fixture plate. The limiting end of the clamp is provided with a stop edge that abuts against the outer surface of the magnetizer to limit the depth of insertion of the clamp into the magnetizer.

[0008] Furthermore, it also includes a cover plate, which is placed on the fixture plate to prevent irregularly shaped workpieces from falling off the fixture plate, and the clamping part clamps the cover plate and the fixture plate.

[0009] Furthermore, the cover plate has a ceramic coating to prevent scratching irregularly shaped workpieces.

[0010] Furthermore, it also includes an elastic element, which is provided between the clamping part and the assembly part, so that the clamping part outputs a preload force to the fixture plate.

[0011] Furthermore, the elastic element is a spring.

[0012] Furthermore, the fixture plate consists of several pieces, and the top surface of the fixture plate is provided with several contour mounting grooves. The fixture plates are stacked, and in two adjacent pieces, the top surface of one fixture plate is in close contact with the bottom surface of the other fixture plate.

[0013] Furthermore, the mounting part is a protrusion with an L-shaped cross-section, and the assembly part is provided with a groove that mates with the protrusion, so that the jig plate is fixedly fitted to the assembly part in a single direction.

[0014] Furthermore, the edge is provided with a hand grip for the operator to grasp the clamp.

[0015] Furthermore, the clamping part is provided with an insertion / removal port, which is used by the operator to put the gripping fixture plate into or take out the clamping part.

[0016] The beneficial effects of adopting the above scheme are as follows:

[0017] 1. Ensure the irregularly shaped workpiece is saturated with magnetization. The fixture clamps the jig plate, and the stop edge limits the depth of the jig plate into the magnetizer, so that the irregularly shaped workpiece reaches the magnetization station;

[0018] 2. Ensure the correct magnetization direction for irregularly shaped workpieces. The contour mounting groove first restricts the direction of the irregularly shaped workpiece, and the mounting and assembly parts work together to restrict the direction of the irregularly shaped workpiece again. The two limiting actions ensure that the irregularly shaped workpiece can be placed into the magnetizer in the correct orientation.

[0019] 3. Ensure operator safety. The clamp's limiting end is equipped with a stop, which not only limits the depth of entry into the magnetizer but also allows the operator to grip the clamp, eliminating the need for the operator's hands to enter the magnetizer and preventing mechanical injury.

[0030] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "Irregularly Shaped Magnet Magnetizing Error-Preventing Fixture" is provided in conjunction with the accompanying drawings.

[0031] The traditional magnetization method involves manually inserting a jig plate 1 into the magnetizer 4 to magnetize the workpiece on the jig plate 1. This method has several drawbacks, including the risk of injury to the operator and the possibility of reverse magnetization. Therefore, this application designs a clamp 2 to hold the jig plate 1. After clamping, the clamp 2 ensures the jig plate 1 is oriented correctly. Then, the jig plate 1 is fed into the magnetization station 41 of the magnetizer 4 by the limiting end of the handheld clamp 2. This eliminates the need for the operator to insert their hand into the magnetizer 4 and ensures saturated magnetization.

[0032] like Figure 4 In the illustrated embodiment, a magnetizing and error-proof fixture 2 for irregularly shaped magnets includes a jig plate 1 and a clamp 2. The jig plate 1 has several contour mounting slots 11 for placing irregularly shaped workpieces to be magnetized. One end of the jig plate 1 has a mounting portion 12. One end of the clamp 2 is an insertion end that extends into the magnetizer 4, and the other end of the clamp 2 is a limiting end that restricts the depth of insertion into the magnetizer 4. The insertion end of the clamp 2 has a clamping portion 22 for clamping the jig plate 1. An assembly portion 21 is provided in the clamping space of the clamping portion 22. The assembly portion 21 cooperates with the mounting portion 12 of the jig plate 1 to position the jig plate 1 and distinguish the orientation of the jig plate 1. The limiting end of the clamp 2 has a stop 23 that abuts against the outer surface of the magnetizer 4 to limit the depth of insertion of the clamp 2 into the magnetizer 4.

[0033] The function of the clamping part 22 is to clamp the fixture plate 1, see [link / reference] Figure 4 In one embodiment, the clamping part 22 is a "U"-shaped structure composed of two side clamping plates and a bottom support plate. The recess of the "U"-shaped structure forms a clamping space. The two side clamping plates clamp the fixture plate 1 located in the clamping space. The bottom support plate supports the fixture plate 1. The top of the clamping space is provided with an assembly part 21, which cooperates with the mounting part 12 at one end of the fixture plate 1.

[0034] When magnetizing irregularly shaped workpieces, the operator first places the workpiece into the contour mounting slot 11 of the fixture plate 1, ensuring the correct orientation of the workpiece. Next, the operator holds the fixture plate 1 and mates its mounting part 12 with the assembly part 21 of the clamp 2, ensuring the fixture plate 1 is correctly oriented on the clamp 2. Simultaneously, the clamping part 22 of the clamp 2 clamps the fixture plate 1 to complete the clamping. Then, the operator holds the retaining edge 23 of the clamp 2 and inserts the end of the clamp 2 into the magnetizer 4, pushing it forward until the retaining edge 23 abuts against the outer surface of the magnetizer 4. At this point, the fixture plate 1 reaches the magnetization station 41. After the magnetizer 4 starts and completes the magnetization, the operator holds the retaining edge 23 to remove the clamp 2.

[0035] To ensure the stability of irregularly shaped workpieces, such as Figure 3 and Figure 4 As shown, a cover plate 3 is added above the fixture plate 1. The cover plate 3 covers the fixture plate 1, blocking irregularly shaped workpieces and preventing them from falling off. The operator places the cover plate 3 and the fixture plate 1 together into the clamping space of the clamping part 22, whereby the clamping part 22 clamps the cover plate 3 and the fixture plate 1. Furthermore, Figure 3 Two examples of cover plate 3 shapes are shown. This case does not limit the specific shape of the cover plate 3, as long as it can achieve the effect of preventing irregularly shaped workpieces from falling off.

[0036] To prevent the cover plate 3 from scratching irregularly shaped workpieces, a smooth ceramic coating is applied to its surface.

[0037] To optimize the clamping effect of the clamping part 22, such as Figure 1 As shown, an elastic element 24 is also provided between the clamping part 22 and the assembly part 21 of this application. Specifically, an elastic element 21 is provided between the clamping plate on one side of the clamping part 22 and the assembly part 21. The elastic element 21 outputs a preload force to the fixture plate 1 through the clamping plate. During clamping, as... Figure 1 As shown, the operator holds one side of the clamping plate and moves it away from the clamping space; then, the operator inserts the jig plate 1 into the clamping space, and simultaneously, the mounting part 12 of the jig plate 1 cooperates with the assembly part 21, so that the jig plate 1 is placed into the clamp 2 in the correct direction; next, the operator releases the clamping plate, and the clamping plate moves towards the clamping space; finally, as shown... Figure 2 As shown, the clamping part 22 is tightly attached to the fixture plate 1, and the spring member applies a preload force to the fixture plate 1 through the clamping part 22, making the fixture plate 1 more securely fixed. Preferably, the elastic member 24 is a spring.

[0038] To improve production efficiency by mass-producing irregularly shaped workpieces, the fixture plate 1 consists of several pieces. The top surface of the fixture plate 1 is provided with several contour mounting grooves 11. The top surface of one fixture plate 1 is in close contact with the bottom surface of another fixture plate 1. In this stacking method, the bottom surface of another fixture plate 1 can also serve as a cover plate 3 for another fixture plate 1.

[0039] The mounting part 12 cooperates with the assembly part 21 to fix the jig plate 1 to the fixture 2 in a unique direction. This cooperation structure can take many forms, but the main idea is to achieve unique assembly by relying on the mutual constraint of the physical shapes of the mounting part 12 and the assembly part 21. Preferably, the mounting part 12 is a protrusion with an L-shaped cross-section, and the assembly part 21 has a groove that mates with the protrusion, so that the jig plate 1 is fixedly fitted to the assembly part 21 in a unique direction.

[0040] The baffle 23 is provided with a hand grip 25, which is convenient for the operator to grasp and place the fixture plate 1 clamped by the clamp 2 into the magnetizer 4.

[0041] The clamping part 22 is provided with a pick-and-place opening 221. When assembling the jig plate 1, the operator grasps the jig plate 1 at the position corresponding to the pick-and-place opening 221 and then assembles the jig plate 1 into the clamp 2. The pick-and-place opening 221 provides space for the operator's hands, making it easy to assemble and disassemble the jig plate 1.

[0042] The foregoing has provided a detailed description of the present application. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are merely for the purpose of helping to understand the technical solutions and core ideas of the present application. It should be noted that those skilled in the art can make various improvements and modifications to the present application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
