Description

Technical Field

[0001] This utility model relates to a circular hole machining device, specifically a CNC one-time tool change type multi-semi-circular hole machining execution device. Background Technology

[0002] In the traditional field of machining semi-circular holes in barrel-shaped workpieces, existing processing equipment has many shortcomings. Most equipment uses a single drill bit, resulting in low processing efficiency and difficulty in meeting the needs of mass production. While some multi-drill bit equipment suffers from problems such as unreasonable drill bit layout and uneven power transmission, leading to low machining accuracy, uneven hole distribution, and poor hole surface quality. Furthermore, the equipment lacks flexibility and versatility, making it difficult to adapt to machining barrel-shaped workpieces of different sizes and specifications. Additionally, the drill bit is prone to deviation and instability during processing, failing to guarantee consistency and reliability. Utility Model Content

[0003] This utility model provides a CNC one-time tool change type multi-semi-circular hole machining execution device to solve the problem of low machining efficiency in the existing single drill bit machining method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides a CNC one-time tool change type multi-semi-circular hole machining execution device, including: a machining frame, a lifting mechanism, a rotary drive mechanism and a drill linkage mechanism. The lifting mechanism is installed on the top of the machining frame, and the workpiece to be processed is installed next to the bottom of the machining frame. The output end of the lifting mechanism is provided with a rotary drive mechanism, and the output end of the rotary drive mechanism is connected to the input end of the drill linkage mechanism. The drill bit linkage mechanism is equipped with a linkage component and at least two drilling output ends. The drill bit linkage mechanism is detachably installed at the output end of the lifting mechanism. The input end of the linkage component in the drill bit linkage mechanism is connected to the output end of the rotary drive mechanism, and the output end of the linkage component is connected to the drilling output ends. The linkage component can drive all drilling output ends to rotate simultaneously under the drive of the rotary drive mechanism.

[0005] Preferably, the linkage component is rotatably mounted inside a housing, and the drilling output end is also rotatably mounted inside the housing, with the housing and the output end of the lifting mechanism being detachably connected.

[0006] Preferably, the drilling output end is a drill bit, and all drill bits are arranged on a circumference.

[0007] Preferably, a guide assembly extending to the middle of the drill bit is installed on the outer casing, the guide assembly is in close contact with the sidewall of the drill bit, and the guide assembly guides the rotation of the drill bit.

[0008] Preferably, the workpiece to be processed has a barrel-shaped structure, the drill bit is used to form a semi-circular hole in the inner wall of the workpiece, and the guide assembly is surrounded by all the drill bits.

[0009] Preferably, the guiding assembly includes a guide shaft and a support plate. The guide shaft is fixed to the output end of the lifting mechanism, and the support plate is fixed on the guide shaft. The support plate guides and supports the drill bit.

[0010] Preferably, the support plate has a notch through which the drill bit passes, and the inner wall of the notch guides the rotation of the drill bit.

[0011] Preferably, the linkage component includes: a power shaft, a power gear, and an output gear. The power shaft is the input end of the linkage component, the power gear is fixed on the power shaft, and the output gear meshes with the power gear. The output gear is the output end of the linkage component, and each output gear is fixed with a drill bit.

[0012] Preferably, the housing includes a mounting cylinder and a mounting cover, which are fastened together to form a mounting cavity. A power gear and an output gear are installed inside the mounting cavity, and the mounting cover is detachably connected to the output end of the lifting mechanism.

[0013] Preferably, the mounting cover is detachably connected to the output end of the lifting mechanism by screws, and the mounting cover is passed through by an anti-rotation pin, which is inserted into the output end of the lifting mechanism.

[0014] Compared with existing technologies, this utility model has the following advantages: This CNC (Computer Numerical Control Machine Tool) single-tool-changing multi-semi-circular hole machining execution device, through the coordinated cooperation of the lifting mechanism, the rotary drive mechanism and the drill linkage mechanism, can realize the simultaneous rotation and precise machining of multiple drills, greatly improving machining efficiency and shortening the machining cycle. It is especially suitable for the machining needs of semi-circular holes on the inner wall of barrel-shaped workpieces in mass production. Secondly, the drills are arranged on a circumference, and the setting of the guide shaft and the support plate plays a key guiding and supporting role. The notch on the support plate allows the middle part of the drill to pass through, and its inner wall is closely attached to the side wall of the drill, providing stable radial support for the drill. This effectively avoids the deviation or shaking of the drill during rotation due to uneven force or its own weight, thereby ensuring the machining quality and accuracy of the semi-circular holes, making the machined hole walls smoother and the dimensions more accurate.

[0021] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4 As shown, this utility model proposes a CNC one-time tool-changing multiple semi-circular hole machining execution device, including: a machining frame 1, a lifting mechanism 2, a rotary drive mechanism 3, and a drill bit 42 linkage mechanism 4. The lifting mechanism 2 is installed on the top of the machining frame 1, and the workpiece 6 to be machined is installed next to the bottom of the machining frame 1. The output end of the lifting mechanism 2 is provided with the rotary drive mechanism 3, and the output end of the rotary drive mechanism 3 is connected to the input end of the drill bit 42 linkage mechanism 4. The drill bit 42 linkage mechanism 4 is provided with a linkage component 41 and at least two drilling output ends. The drill bit 42 linkage mechanism 4 is detachably installed on the output end of the lifting mechanism 2. The input end of the linkage component 41 in the drill bit 42 linkage mechanism 4 is connected to the rotary drive mechanism 4. The output end of mechanism 3 is connected to the drilling output end, and the output end of linkage component 41 is connected to the drilling output end. The linkage component 41 can drive all drilling output ends to rotate simultaneously under the drive of rotary drive mechanism 3. Lifting mechanism 2 includes: lifting cylinder 21, guide rod 22, connecting frame 23 and lifting seat 24. Lifting cylinder 21 is installed on processing frame 1. The output end of lifting cylinder 21 is connected to connecting frame 23. The lower end of connecting frame 23 is connected to lifting seat 24. Lifting seat 24 has a hole for inserting anti-rotation pin 54. There are two guide rods 22, which are located on both sides of lifting cylinder 21. The guide rods 22 pass through processing frame 1 and are connected to lifting seat 24. Rotary drive mechanism 3 is located inside connecting frame 23.

[0022] The lifting mechanism 2 first drives the rotary drive mechanism 3 and the drill bit 42 linkage mechanism 4 to move up and down as a whole, so that the drill bit 42 reaches the appropriate position of the workpiece 6 to be processed. The rotary drive mechanism 3 starts to operate, and the linkage component 41 in the drill bit 42 linkage mechanism 4 connected to its output end moves accordingly, transmitting the rotational power to each drilling output end, driving all drill bits 42 to rotate simultaneously, realizing the synchronous processing of multiple holes on the workpiece. This solves the problems of low processing efficiency and poor consistency of multi-hole processing of traditional single drill bit 42. Through the coordinated cooperation of various components, the processing efficiency is effectively improved, ensuring the processing accuracy and quality of multiple semi-circular holes 61. Moreover, the detachable design of the drill bit 42 linkage mechanism 4 facilitates quick replacement and maintenance according to different processing needs.

[0023] The linkage component 41 is rotatably mounted inside a housing 5, and the drilling output end is also rotatably mounted inside the housing 5. The housing 5 is detachably connected to the output end of the lifting mechanism 2. Its output end drives the linkage component 41 to rotate inside the housing 5. The linkage component 41 transmits power to each drilling output end through a transmission mechanism, realizing synchronous processing of multiple drill bits 42. At the same time, it facilitates quick replacement of the drill bit 42 linkage mechanism 4 according to different processing requirements, increasing the practicality of the device.

[0024] The drilling output end is a drill bit 42, and all drill bits 42 are arranged on a circumference. Through the circumferential arrangement, the spacing between each drill bit 42 is uniform, ensuring that the semi-circular hole 61 produced is highly accurate and evenly distributed on the inner wall of the barrel-shaped workpiece.

[0025] A guide assembly 51 extending to the middle of the drill bit 42 is installed on the outer casing 5. The guide assembly 51 is in close contact with the side wall of the drill bit 42 and guides the drill bit 42 to rotate. The guide assembly 51 both guides the rotation of the drill bit 42 and prevents the drill bit 42 from breaking.

[0026] The workpiece 6 to be processed has a barrel-shaped structure. The drill bit 42 is used to form a semi-circular hole 61 on the inner wall of the workpiece 6. The guide assembly 51 is surrounded by all the drill bits 42. Since the semi-circular hole 61 is relatively long and needs to be continuously inserted into the drill bit 42, the drill bit 42 needs to be designed to be relatively long. However, the drill bit 42 is too long, which may cause it to break during drilling. Since the inner wall of the workpiece 6 is being processed, the inner wall of the semi-circular hole 61 tends to cause the drill bit 42 to move towards the axis of the workpiece 6 during processing. Therefore, the guide assembly 51 is designed to support the drill bit 42 once near the axis, reducing the probability of the drill bit 42 breaking.

[0027] The guide assembly 51 includes a guide shaft 511 and a support plate 512. The guide shaft 511 is fixed to the output end of the lifting mechanism 2, and the support plate 512 is fixed on the guide shaft 511. The support plate 512 guides and supports the drill bit 42.

[0028] The support plate 512 has a notch through which the drill bit 42 passes, and the inner wall of the notch guides the rotation of the drill bit 42. The support plate 512 fixed on the guide shaft 511 guides and supports the drill bit 42, and provides stable radial support for the drill bit 42, ensuring that the drill bit 42 maintains linear motion during rotation and feed, effectively improving machining accuracy and hole surface quality.

[0029] The linkage assembly 41 includes a power shaft 411, a power gear 412, and an output gear 413. The power shaft 411 is the input end of the linkage assembly 41. The power gear 412 is fixed to the power shaft 411, and the output gear 413 meshes with the power gear 412. The output gear 413 is the output end of the linkage assembly 41. Each output gear 413 is fixed with a drill bit 42. The power gear 412 meshes with multiple output gears 413, transmitting power evenly to each output gear 413. Each output gear 413 is fixedly connected to a drill bit 42, thereby driving all drill bits 42 to rotate synchronously. Through precise gear meshing, it is ensured that each drill bit 42 rotates at the same speed and phase, effectively improving machining accuracy and hole surface quality.

[0030] The outer casing 5 includes a mounting cylinder 52 and a mounting cover 53. The mounting cylinder 52 and the mounting cover 53 are fastened together to form a mounting cavity. A power gear 412 and an output gear 413 are installed inside the mounting cavity. The mounting cover 53 is detachably connected to the output end of the lifting mechanism 2. This detachable connection between the mounting cover 53 and the output end of the lifting mechanism 2 facilitates quick disassembly and maintenance of the gear set. CNC (Computer Numerical Control) one-time tool change means that by mounting multiple drill bits 42 on the outer casing, multiple drill bits 42 can be replaced simultaneously when the outer casing 5 is replaced.

[0031] The mounting cover 53 is detachably connected to the output end of the lifting mechanism 2 via screws. An anti-rotation pin 54 passes through the mounting cover 53 and is inserted into the output end of the lifting mechanism 2. The anti-rotation pin 54 prevents the mounting cover 53 from rotating, solving the problems of easy loosening of the linkage component 41 and unstable power transmission in traditional devices. The screw connection ensures a stable connection between the mounting cover 53 and the lifting mechanism 2, while the anti-rotation pin 54 effectively prevents the mounting cover 53 from rotating with the power gear 412, ensuring the stability of power transmission.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
