Description

Technical Field

[0001] This utility model relates to the field of linear motor assembly technology, and in particular to a metal clamp device for mounting neodymium iron boron magnet blocks for linear motors. Background Technology

[0002] Neodymium iron boron magnets, also known as rare-earth permanent magnets, are magnetic materials made primarily from praseodymium and neodymium through a process of extraction and sintering. They are high-performance permanent magnets with characteristics such as high remanence, high coercivity, and high magnetic field strength. They retain their magnetism for extended periods under oxygen-free, high-temperature conditions; exhibit good thermal stability; and demonstrate excellent chemical stability and high corrosion resistance. Their most significant advantage is the ability to fill large volumes of magnets with minimal demagnetization, making them widely used in the electronics industry, machinery manufacturing, and instrumentation.

[0003] When installing neodymium iron boron magnets into a motor, the internal space of the motor is small, and the neodymium iron boron magnets need to be clamped. Current metal clamps are inconvenient to reach into the motor, and the clamping force of tweezers is too weak, making it easy for the neodymium iron boron magnets to fall out, which affects the installation of neodymium iron boron magnets into the motor. Based on this, this application proposes a metal clamp device for installing neodymium iron boron magnet blocks in a linear motor, which can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a metal clamp device for installing neodymium iron boron magnet blocks for linear motors.

[0005] The purpose of this utility model is achieved through the following technical solution: A metal clamp device for installing neodymium iron boron magnet blocks for linear motors includes a main grip, a guide hole is provided in the middle of the outer side of the main grip, and notches are provided on both sides of the outer side of the main grip. A pin is installed inside each of the two notches, and a clamping rod is rotatably installed on the outer side of each of the two pins. A combined rod is slidably installed on one side between the two clamping rods, and a guide rod is installed on one side of the outer side of the combined rod, which passes through the guide hole and the two are slidably engaged. A non-magnetic clamping plate is installed at one end of the outer side of each of the two clamping rods, and a clamping head is installed at the other end of the outer side of each of the two clamping rods.

[0006] Optionally, a through groove is provided at one end of the two clamping rods, and slots are provided on the upper and lower walls of the two through grooves. The two ends of the combined rod are respectively located inside the two through grooves, and limit posts are installed at both ends of the combined rod, which slide in cooperation with the slots.

[0007] Optionally, a limit cap is installed at the outer end of the guide rod, and two springs are sleeved on the outside of the guide rod, which are located on both sides of the main grip respectively.

[0008] Optionally, one end of each of the two clamping rods is recessed to form a groove, and one side of each of the two non-magnetic clamping plates is protruded to form a locking platform, which respectively engages with the groove.

[0009] Optionally, each of the two clamping rods has a tenon groove at one end away from the outside of the groove, and a mortise is installed at one end of each of the two clamps, which respectively engage with the two tenons. Each of the two clamps has an anti-slip protrusion on the side away from the outer surface of the mortise.
