Description

Technical Field

[0001] The utility model relates to the technical field of linear motor equipment, in particular to a high-efficiency cooling linear motor. Background Art

[0002] A linear motor is an electric motor that converts electrical energy into linear mechanical motion. Linear motors usually consist of a fixed part (stator) and a moving part (pusher or slider). They can adopt different working principles and structures according to different designs and applications.

[0003] The structure of a linear motor is relatively simple, and it is usually small and lightweight, making it suitable for applications with limited space. In addition, the mover in a linear motor is the part that actually performs mechanical movement. During movement, it will be heated by the resistance generated by the current passing through the wire, thereby generating heat. However, the mover is often small in size, and the internal space is compact, so the heat dissipation is relatively slow, which affects the operation of the mover. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency cooling linear motor to solve the problem that the mover in the existing linear motor is the part that actually performs mechanical movement, and during the movement it will be heated by the resistance generated by the current passing through the wire, thereby generating heat, and the mover is often small in size, and the internal space is compact, and the heat dissipation is slow, which affects the operation of the mover.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency cooling linear motor, comprising a linear motor body, the linear motor body comprising a stator and a mover sliding on the top of the stator, the outer periphery of the mover being provided with a cooling component for cooling the mover, the cooling component comprising a cooling shell mounted on the top of the mover, the bottom end of the cooling shell being symmetrically and evenly provided with through grooves, a heat collection cavity being provided inside the cooling shell, and a heat conductive block for conducting heat generated by the mover being evenly and symmetrically fixed at the bottom end of the heat collection cavity, the heat conductive block passing through the through groove and abutting against the mover, and the top end of the heat collection cavity being symmetrically provided with heat dissipation fins for conducting heat from the heat collection cavity.

[0006] As a further solution of the utility model: a cooling block for cooling the mover is slidably connected to the bottom end of the cooling shell, and the cooling block is symmetrically slidably connected to the two ends of the mover.

[0007] As a further solution of the utility model: one end of the cooling block is symmetrically connected with an adjusting screw that fixes the cooling shell to the outer periphery of the mover, and one end of the adjusting screw is provided with a fixing block near one end of the mover.

[0008] As a further solution of the utility model: a liquid inlet for the coolant to enter is arranged at one end of the cooling block, and a liquid outlet for the coolant to be discharged is arranged at the end of the cooling block opposite to the liquid inlet.

[0009] As a further solution of the utility model: a connecting rod slidably connected to the cooling shell is fixedly connected to the top of the cooling block, and the connecting rod is symmetrically fixed to one end of the cooling block, and a connecting slide rod slidably connected to the cooling shell is fixedly connected to the top of the connecting rod.

[0010] As a further solution of the utility model: the fixing block is made of polytetrafluoroethylene material.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model first pulls the cooling blocks on both sides of the bottom end of the cooling shell through the connecting rod and the clamping slide rod according to the width of the mover at the top end of the linear motor body, and then sets the cooling shell on the outer periphery of the mover, and then rotates the adjusting screws at both ends of the cooling block to drive the fixing blocks to clamp and fix the two ends of the mover, and the movers with different widths at the top end of the stator can be clamped and fixed to dissipate heat through the connecting rod, the clamping slide rod and the adjusting screw;

[0013] The coolant is injected into the cooling block from the liquid inlet, and then the liquid inlet is sealed by the sealing block. The moving element can be cooled by the cooling block to increase the cooling efficiency of the moving element. Then, the sealing block at one end of the liquid outlet is removed to remove the coolant that cannot be cooled. When the moving element is working, the heat generated is conducted to the inside of the heat collection cavity through the heat conduction block, and then the heat is conducted through the heat dissipation fins at the top of the heat collection cavity. The heat generated by the moving element when working is quickly and efficiently conducted to increase the working stability of the moving element. BRIEF DESCRIPTION OF THE DRAWINGS
