Description

Technical Field

[0001] This utility model relates to wire electrical discharge cutting equipment, and more particularly to a wire threading and guiding mechanism with a multi-directional mating structure. Background Technology

[0002] Patent document CN220921171U discloses an automatic wire threading guide mechanism, which includes an upper wire threading mechanism, a lower wire threading mechanism, and a lifting drive mechanism. The lifting drive mechanism can drive the upper wire threading mechanism and / or the lower wire threading mechanism to rise and fall to achieve docking or separation between the two. A guide tube capable of penetrating a small-diameter hole in the workpiece is provided between the upper and lower wire threading mechanisms. By setting a guide tube capable of penetrating a small-diameter hole in the workpiece, docking of the upper and lower wire threading mechanisms is achieved, thereby realizing automatic wire threading. However, this wire threading guide mechanism uses the method of inserting the guide tube into a fixed hole for docking, which requires high installation accuracy of each component. Collisions and wear are prone to occur during docking, making malfunctions likely. Therefore, it is necessary to optimize its structure to overcome the above-mentioned defects. Utility Model Content

[0003] The purpose of this invention is to provide a wire threading and guiding mechanism with a multi-directional mating structure to improve the stability of its docking process.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A wire threading and guiding mechanism with a multi-directional mating structure, comprising:

[0006] A support load-bearing assembly is installed in the cutting equipment and has a load-bearing space inside;

[0007] The adapter support assembly is installed in the support bearing assembly via a vertical lifting structure and can rise or fall within the support bearing assembly.

[0008] A lifting drive assembly is installed in the support and bearing assembly and cooperates with the transfer carrier assembly through a transmission structure. The lifting drive assembly drives the transfer carrier assembly to rise or fall.

[0009] The conveying traction assembly is installed in the transfer carrier assembly and can rise or fall together with the transfer carrier assembly. It has a cutting wire conveying channel inside, and the cutting wire is pulled by the conveying traction section.

[0010] A conveyor guide assembly is installed in the transfer carrier assembly and can rise or fall together with the transfer carrier assembly. It is connected to the conveyor traction assembly and guides the cutting wire output from the conveyor traction assembly.

[0011] A cooling spray assembly is installed in the support and bearing assembly and corresponds to the position of the conveying guide assembly. When the conveying guide assembly rises or falls, it can approach or move away from the cooling spray assembly. The cutting wire inside the assembly can pass through the cooling spray assembly and be sprayed with coolant by the cooling spray assembly.

[0012] A lateral positioning component is installed in the support and bearing component and corresponds to the cooling spray component and the conveying guide component. The lateral positioning component positions the conveying guide component so that it docks with the cooling spray component.

[0013] Specifically, the supporting load-bearing components include:

[0014] A support base frame is arranged laterally, and the cooling spray assembly and the lateral positioning assembly are installed in the support base frame;

[0027] The clamping guide wheel is installed at the end of the piston rod of the clamping cylinder and can rotate at the end of the piston rod. The clamping cylinder drives the clamping guide wheel to move closer to or away from the traction guide wheel, forming a cutting wire conveying channel between the traction guide wheel and the clamping guide wheel. The traction guide wheel and the clamping guide wheel pull the cutting wire.

[0028] The conveyor guide assembly includes:

[0029] The guide core tube is arranged vertically and installed on the side of the support frame via an adapter block. Its top end is connected to the pressure guide wheel and the traction guide wheel.

[0030] The cooling jet assembly includes:

[0031] The cooling water nozzle is installed in the support base and is connected to the coolant supply equipment. It is positioned at the bottom of the guide tube. After the cutting wire output from the guide tube enters the cooling water nozzle, the cooling water nozzle sprays coolant onto it.

[0032] The lateral positioning components include:

[0033] The positioning block is installed in the support base and located on the side of the cooling water nozzle. When the bottom end of the guide tube is connected to the cooling water nozzle, the positioning block abuts against one side of the guide tube.

[0034] A positioning cylinder is installed in the support base and located on the other side of the cooling water nozzle;

[0035] The positioning block is installed at the end of the piston rod of the positioning cylinder. The positioning cylinder drives the positioning block to move. When the bottom end of the guide core tube is connected with the cooling water nozzle, the positioning block abuts against the other side of the guide core tube. The positioning block and the positioning seat block position the bottom end of the guide core tube, so that the guide core tube is accurately and stably connected with the cooling water nozzle, and the cutting wire in the guide core tube can smoothly enter the cooling water nozzle, which facilitates the automatic wire threading operation.

[0036] The advantages of this utility model are:

[0037] This wire threading and guiding mechanism uses a lead screw lifting drive assembly to raise or lower the transfer carrier assembly, thereby causing the conveying traction assembly and the conveying guide assembly to rise and fall together. The height can be adjusted according to actual needs to adapt to different working conditions and operational requirements, improving the versatility and flexibility of the mechanism. The positioning seat block and positioning moving block of the transverse positioning assembly cooperate with each other to position the bottom end of the guide core tube when it connects with the cooling water nozzle, ensuring accurate and stable connection between the guide core tube and the cooling water nozzle. This ensures that the cutting wire inside the guide core tube smoothly enters the cooling water nozzle, facilitating automatic wire threading, improving the accuracy and reliability of wire threading, reducing manual intervention, and increasing production efficiency.
