Therefore, springs of different outer diameters can be processed, and the entire adjustment process is simple and convenient.

Description

Technical Field

[0001] This utility model relates to the field of lifting mechanism technology, and in particular to a spindle lifting mechanism for a computer numerical control spring coiling machine. Background Technology

[0002] Spring coiling machines, commonly known as spring production machines, generally refer to mechanical equipment used to produce springs. Based on functional characteristics, they are classified as: compression spring machines, extension spring machines, universal machines, disc spring machines, and specialized spring machines such as serpentine spring machines and torsion spring machines. Based on drive method, they are classified as: semi-automatic, automatic, and CNC. The mandrel is a component used to cut the spring steel wire after the spring is coiled. The mandrel lifting mechanism is a crucial part of the spring coiling machine. During spring processing, it is essential to ensure the stability of the mandrel and to allow for adjustment of the mandrel's rise or fall when the spring's outer diameter changes, thereby guaranteeing the quality of the spring products and the lifespan of the mandrel.

[0003] However, existing mandrel lifting mechanisms generally require disassembly using multiple fixing bolts and nuts to loosen the mandrel and adjust its vertical position before fixing it again with bolts and nuts. This method is cumbersome to adjust and has poor reliability. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a spindle lifting mechanism for a computer numerical control spring coiling machine, which can solve the problems of existing spindle lifting mechanisms having the disadvantages of troublesome adjustment and poor reliability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a spindle lifting mechanism for a computer numerical control spring coiling machine, comprising a spring coiling machine base, a front panel fixedly connected to the upper surface of the spring coiling machine base, and a rectangular groove formed in the middle of the left side surface of the front panel;

[0006] The rectangular groove has a guide hole at the bottom, a spring is fixedly connected to the bottom of the guide hole, a second anti-drop sleeve is fixedly connected to the upper end of the spring, and a guide post is fixedly connected to the upper surface of the second anti-drop sleeve.

[0007] The guide post is slidably connected to the inner wall of the guide hole, and a through hole is opened in the middle of the upper surface of the front plate, which communicates with the rectangular groove.

[0008] The inner wall of the through hole is equipped with a lifting mechanism.

[0009] Preferably, the lifting mechanism includes a fixed sleeve, which is fixedly connected to the inner wall of the through hole, and a lifting screw is rotatably connected to the inner wall of the fixed sleeve.

[0010] The lifting screw is fixedly connected to a circular turntable at its upper end outside the fixed sleeve, and two handles are fixedly connected to the upper surface of the circular turntable, which are arranged in a front-to-back manner.

[0011] Preferably, the lower end of the lifting screw rotates through the inner wall of the fixed sleeve and rotates into the interior of the rectangular groove, and the lower end of the lifting screw located inside the rectangular groove is fixedly connected to the first anti-drop sleeve.

[0012] Preferably, a movable sleeve is threaded onto the outer wall of one end of the lifting screw inside the rectangular groove, and connecting plates are fixedly connected to both the front and rear surfaces of the movable sleeve.

[0013] Preferably, a fixing post is fixedly connected to the lower surface of both connecting plates, a core seat is fixedly connected to the lower surface of the two fixing posts, and one end of the guide post located outside the guide hole is fixedly connected to the lower surface of the core seat.

[0014] Preferably, a mandrel is fixedly installed inside the core seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The spindle lifting mechanism for the CNC spring coiling machine drives the moving sleeve to move upward by rotating the lifting screw. The moving sleeve drives the core seat to move upward through two connecting plates and two fixed columns, thereby driving the spindle to move upward. By rotating the lifting screw in both directions, the spindle can be driven to move up and down. Therefore, springs with different outer diameters can be processed. The whole adjustment process is simple and convenient, which improves the practicality of this lifting mechanism.

[0017] (2) The spindle lifting mechanism used in the CNC coiling machine, while the spindle seat moves upward, will drive the guide column to move upward through the inner wall of the guide hole. The guide column plays a guiding and stabilizing role in the overall up and down movement of the spindle seat, improving the stability of the spindle seat during operation. At the same time, the spring plays a buffering role in the overall descent of the spindle seat. Attached Figure Description
