Description

Technical Field

[0001] This application relates to the field of metal pipe processing equipment, and in particular to a drilling and cutting integrated machine tool for locking sleeves. Background Technology

[0002] Locking sleeves, as key components of mechanical connectors, are widely used in machinery manufacturing, the automotive industry, and other fields. In modern manufacturing, the demand for locking sleeves continues to grow, placing higher demands on their processing efficiency and quality. Traditional processes mainly rely on multiple specialized machines to complete different steps, such as drilling and cutting. These machines, through precise operation, ensure product performance and reliability, and occupy an important position in the industry.

[0003] Currently, the processing of locking sleeves typically employs a step-by-step approach. Specifically, the raw material sleeve is first fed into a cutting machine for initial length cutting, and then transferred to a drilling machine for necessary positioning hole machining. In addition, some improvements exist, such as optimizing fixture design to enhance clamping stability or introducing an assembly line layout to shorten transfer time. Nevertheless, the mainstream approach remains based on a design philosophy of independent functional modules.

[0004] However, the above methods reveal significant shortcomings: the need to frequently change workpiece positions between multiple machines not only significantly extends the overall work cycle and increases labor intensity, but also easily accumulates errors due to repeated loading and unloading actions, ultimately affecting product accuracy consistency. These problems are particularly pronounced in high-volume continuous production scenarios, necessitating an integrated solution capable of handling multiple tasks simultaneously to overcome existing limitations. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a drilling and cutting integrated machine tool for locking sleeves. A drilling and cutting integrated machine tool for locking sleeves includes a frame, an automatic feeding component on the frame, and a drilling and cutting mechanism at one end of the frame. The drilling and cutting mechanism includes a drive motor, a cutter head fixedly connected to the output shaft of the drive motor, the cutter head including a drill bit, a cutting head fixedly connected to the end of the drill bit, the inner diameter of the cutting head being smaller than the inner diameter of the drill bit, and a drive component on the frame for driving the cutter head to slide toward the workpiece.

[0006] By adopting the above technical solution, when the user processes the sleeve, the drive assembly drives the cutter head to move towards the sleeve, and the cutting head drills a hole in the sleeve until the drill bit penetrates the hole in the side wall of the sleeve to complete the drilling. After drilling is completed, the automatic feeding assembly drives the sleeve to move forward, the drive assembly drives the cutter head to move towards the sleeve, the automatic feeding assembly drives the sleeve to rotate, and the cutting blade cuts the sleeve along its circumference. This completes the drilling and cutting of the locking sleeve on the machine tool, replacing the traditional method of cutting on one machine and drilling on another, thereby improving processing efficiency and reducing manpower.

[0007] Preferably, a guide slope is provided on the connection side of the drill bit and the cutting head, and a spiral line is provided on the guide slope.

[0008] By adopting the above technical solution, when the user uses the spiral, it facilitates the drilling of the hole and guides the drill bit until the drilling is completed.

[0009] Preferably, the drive assembly includes a power motor fixedly connected to the frame, a sliding seat fixedly connected to the output shaft of the power motor, and the drive motor slidably connected to the top of the sliding seat. The sliding direction of the sliding seat is perpendicular to the feeding speed of the sleeve.

[0010] By adopting the above technical solution, when the user uses the device, the power motor works, which can push the sliding seat to slide towards the sleeve, and then push the cutter head to slide towards the sleeve to achieve cutting and drilling.

[0011] Preferably, a guide rail is fixedly connected to the frame, and a slider is fixedly connected to the bottom of the sliding seat, with the slider slidably connected to the guide rail.

[0012] By adopting the above technical solution, when the user uses it, the drive motor pushes the sliding seat to slide, and the slider slides on the guide rail, which can guide and limit the sliding seat, making the sliding seat slide more stably.

[0013] Preferably, accordion covers are fixedly connected to both sides of the sliding seat, and the two ends of the accordion covers away from the sliding seat are fixedly connected to the frame to cover the guide rail.

[0014] By adopting the above technical solution, when the user uses the bellows cover, its telescopic function can follow the extension and contraction of the sliding seat, preventing the debris generated during drilling from falling onto the guide rail, thereby preventing the debris from affecting the normal sliding of the slider.

[0015] Preferably, a limit cylinder is hinged on the frame, and an arc-shaped plate is fixedly connected to the end of the piston rod of the limit cylinder. A pressure wheel is provided on the top of the arc-shaped plate, and the pressure wheel is used to abut against the top of the sleeve.

[0016] By adopting the above technical solution, when the user uses the device, the piston rod of the limiting cylinder extends and pushes the arc plate to flip downward, so that the clamping wheel abuts against and supports the top of the sleeve, thereby limiting the vertical direction of the sleeve.

[0017] Preferably, a material-blocking cylinder is fixedly connected to the frame. The material-blocking cylinder is located on the side of the frame away from the drive motor. A baffle is fixedly connected to the end of the piston rod of the material-blocking cylinder. The baffle is used to abut against the side of the sleeve away from the drive motor.

[0018] By adopting the above technical solution, when the user uses the material-blocking cylinder, the piston rod extends and pushes the baffle against the side wall of the casing to limit the casing in the horizontal direction, reducing the swaying of the casing during drilling or cutting.

[0019] Preferably, a feeding channel is fixedly connected to the frame, the feeding channel is located below the cutter head, and the feeding channel is inclined downward.

[0020] By adopting the above technical solution, when the user uses the device, the cut locking sleeve falls into the feeding channel, and the feeding channel guides the locking sleeve outward. Attached Figure Description

Detailed Implementation

[0023] The following will be combined with the appendix Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model.

[0024] This application provides a drilling and cutting integrated machine tool for locking sleeves, mainly comprising a frame 1, an automatic feeding assembly 2, and a drilling and cutting mechanism 3. The core component of the drilling and cutting mechanism 3 is a drive motor 31 that drives a cutter head 32 to complete drilling and cutting operations. The cutter head 32 consists of a drill bit 321 and a cutting head 322, with a guide bevel and helical design between them to ensure a more precise and stable drilling process. The automatic feeding assembly 2 can push the sleeve towards the cutter head 32 and can also push the sleeve to rotate around its axis.

[0025] A feeding channel 11 is fixedly connected to the frame 1. The feeding channel 11 is located below the cutter head 32. The feeding channel 11 is set at an angle downward. The cut locking sleeve falls into the feeding channel 11, and the feeding channel 11 guides the locking sleeve outward.

[0026] Specifically, the cutting head 32 comprises two key components: a drill bit 321 and a cutting head 322. The drill bit 321 is made of high-strength alloy steel, possessing excellent wear resistance; the cutting head 322 is made of cemented carbide, exhibiting extremely high hardness and a long service life. The two are connected by a guide bevel formed through precision grinding, and a helical structure is added to the bevel to optimize the cutting path and prevent deviation.

[0027] In addition, the main power source is a power motor 33 mounted on the frame 1. A sliding seat 34 is fixedly connected to the output shaft of the power motor 33. The drive motor 31 is slidably connected to the top of the sliding seat 34. The sliding direction of the sliding seat 34 is perpendicular to the feeding speed of the sleeve. A guide rail 342 is fixedly connected to the frame 1. A slider 341 is fixedly connected to the bottom of the sliding seat 34 and is slidably connected to the guide rail 342. Bellows covers 35 are fixedly connected to both sides of the sliding seat 34. The two ends of the bellows covers 35 away from the sliding seat 34 are fixedly connected to the frame. 1. The guide rail 342 is blocked; the power motor 33 works, which can push the sliding seat 34 to slide towards the sleeve, and then push the cutter head 32 to slide towards the sleeve to realize cutting and drilling; the drive motor 31 pushes the sliding seat 34 to slide, and the slider 341 slides on the guide rail 342, which can guide and limit the sliding seat 34, making the sliding seat 34 slide more stably; the extension and retraction function of the bellows cover 35 can follow the extension and retraction of the sliding seat 34 to prevent the debris generated by drilling from falling onto the guide rail 342, thereby preventing the debris from affecting the normal sliding of the slider 341. A limiting cylinder 4 is hinged to the frame 1. An arc-shaped plate 41 is fixedly connected to the end of the piston rod of the limiting cylinder 4. A pressure wheel 42 is provided on the top of the arc-shaped plate 41. The pressure wheel 42 is used to abut against and support the top of the sleeve. When the piston rod of the limiting cylinder 4 extends, it pushes the arc-shaped plate 41 to flip downward, so that the pressure wheel 42 abuts against and supports the top of the sleeve, thus limiting the vertical direction of the sleeve. A material-stopping cylinder 5 is fixedly connected to the frame 1. The material-stopping cylinder 5 is located on the side of the frame 1 away from the drive motor 31. A baffle 51 is fixedly connected to the end of the piston rod of the material-stopping cylinder 5. The baffle 51 is used to abut against the side of the sleeve away from the drive motor 31. When the piston rod of the material-stopping cylinder 5 extends, it pushes the baffle 51 against the side wall of the sleeve, thus limiting the horizontal direction of the sleeve and reducing the shaking of the sleeve during drilling or cutting.

[0028] The implementation principle of this embodiment is as follows: After the equipment is started, the automatic feeding component 2 pushes the sleeve to be processed to the designated position. Then, the power motor 33 drives the sliding seat 34 to carry the cutter head 32 closer to the sleeve. In the initial stage, the cutting head 322 first cuts into the surface to form an initial opening. Then, the drill bit 321 gradually enlarges the diameter until it penetrates the side wall to generate the required hole. After that, the above steps are repeated, the angle is adjusted and the sleeve is moved forward for a certain distance before switching to the circumferential sawing mode to cut off the entire sleeve and finally complete the integrated molding process. Compared with the previous decentralized independent production lines, this greatly shortens the turnover cycle and significantly reduces labor consumption, achieving good economic and social benefits. The difference between this embodiment and the previous embodiment lies in the addition of a safety detection step. Specifically, a sensor array is added to the existing system to collect various operating parameters in real time and compare them with preset thresholds. Once an anomaly is detected, an alarm is immediately triggered to prompt staff to check and repair, thereby minimizing potential risks and ensuring long-term reliable operation.
