Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a four-axis tapping machine. Background Technology

[0002] In the field of machining, tapping is a common machining process used to create internal threads on workpieces. Traditional tapping equipment typically employs a single-axis design, processing only one hole at a time, resulting in low efficiency. This is especially true when machining multi-hole or complex workpieces, often requiring multiple clamping and repetitive operations, leading to low production efficiency and extended processing cycles. Furthermore, single-axis tapping equipment has limited functionality, making it difficult to adapt to the machining needs of different thread specifications, thus increasing equipment purchase and maintenance costs.

[0003] With the development of industrial automation, the requirements for processing efficiency and quality are constantly increasing, highlighting the limitations of traditional single-axis tapping equipment. For example, when machining multi-hole workpieces, operators need to frequently adjust the workpiece position or change equipment, which not only increases labor intensity but also easily leads to a decrease in processing accuracy due to operational errors. At the same time, single-axis equipment cannot meet the needs of mass production, limiting the overall efficiency of the production line.

[0004] To address these issues, improved tapping equipment has emerged in the market, such as tapping machines with a dual-axis design. These machines, through simultaneous dual-axis machining, can improve production efficiency to some extent. However, existing dual-axis tapping equipment still has shortcomings in workpiece clamping, automated operation, and adaptability to diverse machining needs. For example, the clamping mechanism design is not flexible enough, which may cause the workpiece to shift during machining, affecting machining accuracy; at the same time, the equipment's applicability is limited, making it difficult to simultaneously meet the machining needs of different thread specifications. Utility Model Content

[0005] The purpose of this invention is to provide a four-axis tapping machine to solve the above-mentioned problems.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model provides a four-axis tapping machine, including a tapping machine base, tapping mechanisms, a waste trough, a material trough, a conveyor belt, a hopper, and a trough. At least two tapping mechanisms are installed on the tapping machine base. The waste trough and the tapping machine base are integrated. The material trough and the tapping machine base are integrated. A baffle is provided between the waste trough and the material trough and is fixedly connected to the tapping machine base. The hopper is installed on the tapping mechanisms. The trough is fixedly installed on the tapping machine base. Both ends of the conveyor belt are connected to the tapping mechanisms and the trough, respectively.

[0008] The tapping mechanism includes a main body, a material tray, a tapping drill bit, a baffle plate, a limiter, and a discharge hopper. The material tray is movably mounted on the main body. The tapping drill bit is equipped with a stepper motor and a lifting cylinder. The tapping drill bit is mounted on the output end of the stepper motor, and the stepper motor is mounted on the output end of the lifting cylinder. The lifting cylinder is fixedly mounted on the main body. The baffle plate is mounted above the material tray. The limiter is mounted on the side of the material tray. The discharge hopper is mounted on the main body and located below the material tray.

[0009] In the above technical solution, the operator puts the material to be processed into the trough, starts the equipment, and the material is arranged through the trough and enters the conveyor belt. The conveyor belt transports the material to the material position of the material tray. The material tray rotates under the drive of the servo motor, sending the material to the bottom of the tapping drill bit. The limit switch starts to work to clamp and fix the material, ensuring that the material will not shift during processing. The tapping drill bit moves downward under the drive of the stepper motor and the lifting cylinder to perform the tapping operation on the material. After tapping is completed, the limit switch resets, the material is released, the material tray continues to rotate, and the material is pushed out of the material tray after contacting the baffle plate and discharged through the hopper, completing the entire processing process.

[0010] In one embodiment, at least two conveyor belts and at least two troughs are provided, and each is connected to a tapping mechanism via a conveyor belt. In this technical solution, the material is arranged through the troughs and moves along the conveyor belt to the tapping mechanism to dock with the material tray, thereby completing the automatic feeding operation.

[0011] In one embodiment, a servo motor connected to a material tray is installed on the main body of the mechanism. The servo motor controls the rotation of the material tray to feed materials. In this technical solution, the material tray is transported by the servo motor, so that the materials can be tapped and moved.

[0012] In one embodiment, the limiter includes a limit cylinder, a movable rod, a fixed rod, a limit rod, and a guide rail. The two ends of the movable rod are movably mounted on the guide rail and the output end of the limit cylinder, respectively. The middle part of the movable rod is movably mounted on the fixed rod, which is fixedly connected to the main body of the mechanism. The limit rod is movably mounted on the guide rail, and the guide rail is fixedly mounted on the main body of the mechanism. Two sets of the movable rod, fixed rod, limit rod, and guide rail are provided, and the two sets of movable rods, fixed rods, limit rods, and guide rails are mirror-distributed along the output end of the limit cylinder. In this technical solution, the limit cylinder of the limiter drives the movable rod to move along the guide rail, causing the limit rod to cooperate with the material tray to clamp and fix the material, ensuring that the material will not shift during processing.

[0013] In one embodiment, the material tray is provided with several material positions, and holes are opened at the bottom of the material positions. In this technical solution, the waste generated during the processing falls into the waste trough through the holes at the bottom of the material tray, thereby realizing the automatic collection and processing of waste.

[0014] In one embodiment, the two limiting rods are installed on the sides of two material positions of the material tray to limit and fix the material on the material position after the material tray rotates.

[0015] The advantages or beneficial effects of the above technical solutions include at least the following:

[0016] 1. Improved efficiency: The dual-axis tapping machine can process two holes, significantly improving production efficiency. At the same time, multiple holes can be processed in one clamping, reducing repetitive operations.

[0017] 2. Wide range of applications, suitable for processing multi-hole or complex workpieces, reducing equipment requirements, and can install taps of different specifications at the same time to meet diverse needs;

[0018] 3. Cost savings: One dual-axis machine can replace multiple single-axis machines, reducing procurement and maintenance costs. Attached Figure Description
