Description

Technical Field

[0001] This utility model relates to the field of mechanical zeroing technology, and in particular to a spring electromagnet combined electromagnetic zeroing structure. Background Technology

[0002] Mechanical zeroing is required during machining processes. Mechanical zeroing is an operation that adjusts the moving parts or measuring systems of mechanical equipment to a known, fixed "zero point" position. It is usually used to ensure the accuracy, repeatability, and reliability of equipment and is an important part of equipment installation, commissioning, repair, or periodic maintenance. Traditional mechanical zeroing usually uses an electromagnet to attract the moving parts to the zero position.

[0003] Existing mechanical zeroing techniques cannot adequately protect against collisions, and direct attraction by electromagnets can result in significant impact forces, easily damaging the equipment. Utility Model Content

[0004] The main purpose of this utility model is to provide a spring electromagnet combined electromagnetic zero-position structure, which aims to solve the problem that it is not possible to provide good anti-collision protection during mechanical zeroing. Direct attraction of the electromagnet will result in a large impact force, which can easily damage the equipment.

[0005] To achieve the above-mentioned utility model objectives, the first aspect of this utility model proposes a spring electromagnet combined electromagnetic zero-position structure including a base, a mounting bracket and a fixing bracket fixedly installed on the top of the base, the mounting bracket and the fixing bracket having one end face parallel, an electromagnet installed inside the mounting bracket, and an anti-collision mechanism provided inside the fixing bracket.

[0006] The anti-collision mechanism includes a sliding frame, an anti-collision rubber head, a limiting rod, and a second spring. The limiting rod is fixedly installed on one side of the sliding frame and slidably connected inside the fixed frame. The sliding frame is slidably connected to one side of the fixed frame through the limiting rod. The second spring is fixedly installed on the side wall of the sliding frame, and the anti-collision rubber head is installed on one side of the sliding frame.

[0007] Furthermore, the anti-collision rubber head is located on one side of the electromagnet;

[0008] Furthermore, a limit frame is fixedly installed on one side of the sliding frame, and double-sided adhesive is fixedly installed on one side of the anti-collision rubber head, with the anti-collision rubber head adhering to the inside of the limit frame through the double-sided adhesive;

[0009] Furthermore, the anti-collision rubber head has a cavity inside, and a diamond-shaped reinforcing rib is fixedly installed inside the cavity;

[0010] Furthermore, the fixed frame has a liquid storage cavity inside, a movable plate is fixedly installed at one end of the sliding frame, the movable plate has a through hole inside, and half of the liquid storage cavity is filled with damping fluid.

[0011] Furthermore, the through hole is a tapered hole;

[0012] Furthermore, the mounting bracket is equipped with a fine-tuning mechanism;

[0013] Furthermore, the fine-tuning mechanism includes a movable plate, an adjusting component, a first spring, a threaded rod, and a guide rail. The movable plate is fixedly installed at one end of the electromagnet, the guide rail is fixedly installed inside the mounting frame, the movable plate is slidably connected to the side wall of the guide rail, the threaded rod is rotatably connected inside the mounting frame, the threaded rod is movably connected to the movable plate, and the adjusting component is fixedly installed at one end of the threaded rod.

[0016] Beneficial effects:

[0017] This utility model discloses a spring-electromagnetic combination electromagnetic zero-position structure, which adopts a design with an anti-collision mechanism inside the fixed frame. The anti-collision rubber head can first contact the moving part, and then the second spring starts to store and compress. Then the moving part continues to slowly approach, compressing the spring. When the distance is close to the electromagnet, the electromagnet will generate an attractive force on the moving part, stop driving the moving part, and make the electromagnet attract the moving part until it reaches the zero position of the electromagnet. This makes the impact force of the moving part at the zero position of the electromagnet close to zero, so as to achieve a better anti-collision protection effect. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly and specifically defined.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0029] Reference Figure 1-4 An embodiment of this utility model provides a spring electromagnet combined electromagnetic zero position structure, including a base 1, a mounting bracket 2 and a fixing bracket 3 fixedly installed on the top of the base 1, the mounting bracket 2 and the fixing bracket 3 having one end face parallel, an electromagnet 21 installed inside the mounting bracket 2, and an anti-collision mechanism provided inside the fixing bracket 3.

[0030] The anti-collision mechanism includes a sliding frame 31, an anti-collision rubber head 33, a limiting rod 35, and a second spring 34. The limiting rod 35 is fixedly installed on one side of the sliding frame 31 and is slidably connected inside the fixed frame 3. The sliding frame 31 is slidably connected to one side of the fixed frame 3 through the limiting rod 35. The second spring 34 is fixedly installed on the side wall of the sliding frame 31, and the anti-collision rubber head 33 is installed on one side of the sliding frame 31.

[0031] This embodiment implements a design that incorporates an anti-collision mechanism inside the fixed frame 3. The anti-collision rubber head 33 can first contact the moving part, and then the second spring 34 begins to compress under force. The moving part continues to slowly approach, compressing the spring. When the distance approaches the electromagnet 21, the electromagnet 21 will generate an attractive force on the moving part, stopping the drive on the moving part and causing the electromagnet 21 to attract the moving part until it reaches the zero position of the electromagnet 21. This makes the impact force of the moving part at the zero position of the electromagnet 21 close to zero, achieving a better anti-collision protection effect. When the attraction force of the electromagnet 21 is greater than the elastic force of the second spring 34, the mechanical zeroing function can be stably realized.

[0032] In some embodiments, such as Figure 1 As shown, the anti-collision rubber head 33 is located on one side of the electromagnet 21.

[0033] It should be noted that by placing the anti-collision rubber head 33 on one side of the electromagnet 21, the anti-collision rubber head 33 can make contact with the moving parts first.

[0034] In some embodiments, such as Figure 3As shown, a limit frame 32 is fixedly installed on one side of the sliding frame 31, and double-sided adhesive 333 is fixedly installed on one side of the anti-collision rubber head 33. The anti-collision rubber head 33 is adhered to the inside of the limit frame 32 by the double-sided adhesive 333.

[0035] It should be noted that the anti-collision head 33 can be easily removed and installed by using double-sided tape 333 to install the anti-collision head 33.

[0036] In some embodiments, such as Figure 3 As shown, the anti-collision rubber head 33 has a cavity 331 inside, and a rhomboid reinforcing rib 332 is fixedly installed inside the cavity 331.

[0037] It should be noted that by setting the diamond-shaped reinforcing ribs 332, the internal cavity 331 of the anti-collision rubber head 33 can be supported, making the anti-collision rubber head 33 less prone to deformation.

[0038] In some embodiments, such as Figure 2 As shown, the fixed frame 3 has a liquid storage chamber 37 inside, and a movable plate 36 is fixedly installed at one end of the sliding frame 31. The movable plate 36 has a through hole 361 inside. Half of the liquid storage chamber 37 is filled with damping fluid 371, and the through hole 361 is a conical hole.

[0039] It should be noted that the reservoir 37 can be used to store damping fluid 371. The through hole 361 allows the damping fluid 371 to pass through the moving plate 36. By providing the damping fluid 371, the moving plate 36 has a certain damping effect when the block moves to the end position, so that the moving part has a strong damping effect when it is about to come into contact with the electromagnet 21, thereby further buffering and reducing the impact on the moving part.

[0040] In some embodiments, such as Figure 4 As shown, the mounting frame 2 is equipped with a fine-tuning mechanism, which includes a movable plate 211, an adjusting component 22, a first spring 24, a threaded rod 25, and a guide rail 26. The movable plate 211 is fixedly installed at one end of the electromagnet 21, and the guide rail 26 is fixedly installed inside the mounting frame 2. The movable plate 211 is slidably connected to the side wall of the guide rail 26. The threaded rod 25 is rotatably connected inside the mounting frame 2 and is movably connected to the movable plate 211. The adjusting component 22 is fixedly installed at one end of the threaded rod 25.

[0041] It should be noted that the adjusting component 22 can be used to control the rotation of the threaded rod 25, and the guide rail 26 can restrict the movable plate 211 from rotating. This allows the threaded rod 25 to drive the movable plate 211 to move inside the mounting frame 2 during rotation, thereby achieving the effect of fine-tuning the electromagnet 21 and enabling fine-tuning of the zero position.

[0042] In some embodiments, such as Figure 4As shown, a first spring 24 is fixedly installed inside the mounting bracket 2. One end of the first spring 24 is in contact with the movable plate 211, and the other end of the first spring 24 is in contact with the inner wall of the mounting bracket 2.

[0043] It should be noted that by setting the first spring 24, the movable plate 211 can be supported, thus preventing the movable plate 211 from shaking after adjustment.

[0044] In some embodiments, such as Figure 4 As shown, a connecting wire 23 is fixedly installed at the connecting end of the electromagnet 21, and the connecting wire 23 is distributed in a spiral shape inside the mounting bracket 2.

[0045] It should be noted that the connecting wire 23 can be used to energize the electromagnet 21. By making the connecting wire 23 spirally distributed inside the mounting bracket 2, the electromagnet 21 will not exert a large pulling force on the connecting wire 23 during fine adjustment.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
