Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire thread sleeve processing technology, specifically a large-diameter wire thread sleeve cutting device with a buffer mechanism. Background Technology
[0002] Wire thread inserts are a new type of internal thread fastener. They are spring-shaped concentric bodies with internal and external threads, precisely machined from high-strength, high-precision, and smooth-surfaced cold-rolled diamond-shaped stainless steel wire. They are mainly used to reinforce and protect the internal threads of low-strength materials. The working principle of wire thread inserts is to form an elastic connection between the screw and the internal thread of the base, eliminating thread manufacturing errors and improving connection strength. However, cutting is required during the forming and processing of wire thread inserts. Existing cutting devices have complex structures and cannot adjust the cutting height, so they cannot be universally used for processing different types of workpieces. Furthermore, the existing cutting devices operate by using a motor to drive a cam to rotate, which in turn presses the cutter to cut. The cutting is a hard contact without buffering, which can damage the motor when cutting large-diameter wire thread inserts. In addition, a spring is required to reset the cutter, which is prone to damage. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a large-diameter wire thread insert cutting device with a buffer mechanism. The device has a simple structure, can not only adapt to the processing settings of different types of wire thread inserts, but also has a buffer function during cutting, avoiding damage to the motor caused by rigid connection, and saving the spring added for tool reset. It is more convenient to use and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a large-diameter steel wire thread sleeve cutting device with a buffer mechanism, comprising a mounting base, two vertical sliding seats on the upper surface of the mounting base, the vertical sliding seats having a U-shaped cross-section, an adjustable cutting seat between the two vertical sliding seats, the adjustable cutting seat being uniformly connected to the two vertical sliding seats via a sliding connection assembly, a vertical adjustment drive component for adjusting the adjustable cutting seat being provided in the middle of the upper surface of the sliding connection assembly, two sliding rails being fixedly mounted on the front surface of the adjustable cutting seat, the sliding rails having an L-shaped cross-section, a sliding block that can slide vertically between the two sliding rails, a cutting tool being provided at the center of the lower end of the sliding block, a cutting drive motor being fixed in the middle of the upper surface of the adjustable cutting seat, the output shaft end of the cutting drive motor being connected to the sliding block via a crank-connecting rod mechanism.
[0005] Furthermore, the sliding connection assembly includes a sliding rail fixed inside the vertical sliding seat, and the adjustable cutting seat is provided with a sliding groove corresponding to the sliding rail. The cooperation between the sliding rail and the sliding groove makes the adjustable cutting seat slide up and down more smoothly.
[0006] Furthermore, the up-and-down adjustment drive includes an adjusting threaded column connected to the mounting base via a bearing. The adjustable cutting seat has a threaded blind hole in the middle, which is connected to the adjusting threaded column via a threaded connection. A rotating nut is fixed to the outer side of the lower end of the adjusting threaded column. Rotating the rotating nut can drive the adjusting threaded column to rotate. The relative rotation of the adjusting threaded column and the threaded blind hole can drive the adjustable cutting seat to move up and down. The adjustable cutting seat can drive the sliding track and the cutting tool to move up and down, thereby adjusting the lowest point of the cutting tool during movement. This can meet the needs of different models of wire thread sleeve forming machines.
[0007] Furthermore, the crank-connecting rod mechanism includes a crank mounted on the end of the output shaft of the cut-off drive motor, a connecting rod connected to the crank, and the lower end of the connecting rod connected to a sliding block via a pin.
[0008] Furthermore, the cutting tool includes a tool holder fixed to the sliding block by bolts. A cutting blade is fixed in the middle of the lower end of the tool holder. The lower end of the cutting blade has a tapered structure. When the cutting drive motor is running, the sliding block is driven to move up and down reciprocally by the crank and connecting rod. The reciprocating motion of the sliding block drives the cutting blade to move up and down. The reciprocating up and down motion of the cutting blade repeatedly cuts the wire thread sleeve, making cutting more convenient. Moreover, the crank and connecting rod mechanism avoids the rigid connection of the cam push in the conventional structure, and has a buffering effect.

When the cutting drive motor 7 is running, the crank 62 and connecting rod 61 drive the sliding block 5 to move up and down reciprocally. The reciprocating motion of the sliding block 5 drives the cutting blade 42 to move up and down. The reciprocating motion of the cutting blade 42 repeatedly cuts the wire thread insert, making cutting more convenient. Furthermore, the crank-connecting rod mechanism 6 avoids the rigid connection of the cam-driven mechanism in conventional structures, providing a buffering effect. This large-diameter wire thread insert cutting device with a buffering mechanism has a simple structure. It can not only adapt to the processing settings of different types of wire thread inserts, but also has a buffering function during cutting, avoiding damage to the motor caused by rigid connection, and saving the spring added for tool reset, making it more convenient to use.
