Description

Technical Field

[0001] This invention relates to the field of chamfering technology for parts, and more particularly to a mobile chamfering device for parts edges. Background Technology

[0002] In the field of mechanical manufacturing, the edges of parts often need to be chamfered during the machining process. This process can remove burrs and sharp edges left after machining, preventing scratches to operators or damage to other mating parts during assembly. It can also reduce stress concentration, improve the structural stability and service life of parts, and optimize the appearance of parts to meet the requirements of product precision and aesthetics. Among them, shaft parts are key components of mechanical transmission systems. They need to fit with other components through inner holes. To ensure smooth fit, reduce assembly resistance, and prevent deformation of the inner hole edges due to impacts during use, chamfering the inner hole edges of shaft parts has become an indispensable key process in the production process of shaft parts.

[0003] Currently, there are two significant limitations in the chamfering of the inner hole edges of shaft components. First, the angle adaptability is poor. When different angles need to be machined, it is necessary to frequently change the tool mounting bracket with the corresponding angle specifications. After each change, the tool position must be recalibrated, making the operation cumbersome and time-consuming, significantly increasing the preparation time. Second, the machining fit is insufficient. Since the outer diameter of the existing mounting bracket is fixed, it cannot be flexibly adjusted according to the actual hole diameter of the shaft component. As a result, the tip of the chamfering tool cannot effectively fit with the inner hole wall when it is first inserted into the hole. During the machining process, the tool is prone to unnecessary ineffective displacement, which not only affects the stability of the chamfering accuracy but also consumes additional machining time, resulting in low overall machining efficiency, poor flexibility, and low practicality.

The fixed base is fixedly installed on the top of the worktable, and the moving base is inserted into the top of the fixed base. The moving push rod is fixedly installed on the side of the fixed base, and one end of the push rod is fixedly installed on the side of the moving base.

[0007] Furthermore, the clamping assembly also includes a fixed clamping block and a fixed push rod. The fixed clamping block is inserted into the top of the worktable, and the fixed push rod is fixedly installed on the side of the worktable. One end of the push rod is fixedly installed on the side of the fixed clamping block.

[0008] Furthermore, the inserting mechanism is provided in three sets, and the three sets of inserting mechanisms are arranged in a circular array on the side of the rotating disk.

[0009] Furthermore, the moving mechanism also includes a drive motor, which is fixedly installed inside the moving base, and the drive motor and the rotating disk are connected by a gear set.

[0010] Furthermore, the control mechanism also includes an angle positioning rod and an outer diameter positioning rod. The angle positioning rod is rotatably connected to the inside of the rotary disk along the axial direction, and the outer diameter positioning rod is rotatably connected to the inside of the rotary disk along the radial direction. Both the angle positioning rod and the outer diameter positioning rod are threaded rods. The angle positioning rod is screwed into the inside of the control frame through the rod body thread, and the outer diameter positioning rod is screwed into the inside of the positioning frame of one of the cutting mechanisms through the rod body thread.

[0011] Furthermore, the planing mechanism also includes an angled connecting rod, with its two ends rotatably connected to the bottom of the planing tool holder and the side of the driven block, respectively.

[0012] Furthermore, the control frame is provided with a displacement groove arranged radially along the rotating disk on its exterior, and a displacement rod is provided on the side of the active block, the displacement rod being inserted into the interior of the displacement groove.

[0014] Furthermore, the driven block has a driven protrusion inside, and the linkage rod has a driven groove with a spiral direction on the outside, with the driven protrusion inserted into the driven groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The chamfering assembly allows for rapid adjustment of both the chamfering outer diameter and chamfering angle without disassembling the frame or the cutting tool. These two adjustment functions are independent and do not interfere with each other. Specifically, for the chamfering outer diameter, the rotational outer diameter of the three cutting mechanisms can be directly adjusted via the outer diameter positioning rod to accommodate the inner holes of shaft parts with different diameters. For the chamfering angle, only the tilt angle of the cutting tool needs to be adjusted via the angle positioning rod. The entire adjustment process eliminates the need for disassembly and assembly of components within the chamfering assembly and repeated tool position calibration. This significantly simplifies the operation, eliminating the tedious disassembly and calibration processes of traditional machining. It also ensures the fit between the tool and the inner hole wall after each adjustment, effectively preventing unnecessary displacement. Ultimately, it can adapt to the chamfering needs of various shaft parts, improving the equipment's versatility and flexibility, reducing process preparation time and machining errors, further ensuring machining accuracy, and significantly improving overall machining efficiency.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please refer to Figures 1 to 11 Example 1:

[0041] This invention proposes a mobile component edge chamfering processing device, comprising: a clamping assembly 1, which includes a worktable 101; and a chamfering assembly, which consists of a moving mechanism 2, a control mechanism 3, and a cutting mechanism 4.

[0042] The moving mechanism 2 includes a fixed base 201, a moving base 202, a moving push rod 203, and a drive motor 204. The fixed base 201 is fixedly installed on the top of the worktable 101, and the moving base 202 is inserted into the top of the fixed base 201. The moving push rod 203 is fixedly installed on the side of the fixed base 201, and one end of the push rod 203 is fixedly installed on the side of the moving base 202. The drive motor 204 is fixedly installed inside the moving base 202. The control mechanism 3 includes a rotary table 301 and a control frame 302. The rotary table 301 is rotatably connected to the top of the moving base 202, and... The control frame 302 is inserted into the interior of the rotary table 301; the planing mechanism 4 includes a positioning frame 401, a planing tool holder 402, a linkage rod 404, a driven block 405, and an active block 406. The positioning frame 401 is inserted into the interior of the rotary table 301, and one end of the planing tool holder 402 is rotatably connected to the top side of the positioning frame 401. The linkage rod 404 is rotatably connected to the interior of the positioning frame 401, and the driven block 405 is inserted into the front side of the positioning frame 401. The active block 406 is inserted into the rear side of the positioning frame 401. A planing tool 5 is detachably and fixedly installed on the top of the planing tool holder 402.

[0043] The fixture assembly 1 further includes a fixed clamping block 102 and a fixed push rod 103. The fixed clamping block 102 is inserted into the top of the worktable 101, and the fixed push rod 103 is fixedly installed on the side of the worktable 101. One end of the push rod 103 is fixedly installed on the side of the fixed clamping block 102. The cutting mechanism 4 is provided in three sets, and the three sets of cutting mechanisms 4 are arranged in a circular array on the side of the rotary table 301. In use, when it is necessary to chamfer the edge of the inner hole of the shaft component, the shaft component is fixed to the top of the worktable 101 by the fixed clamping block 102. The movable push rod 203 drives the movable seat 202 to move. The drive motor 204 and the spindle 301 are connected by a gear set. The drive motor 204 drives the spindle 301 to rotate. When the spindle 301 rotates, it can drive the three sets of cutting mechanisms 4 to rotate synchronously. When the cutting mechanism 4 moves with the movable seat 202 and extends into the edge of the inner hole of the shaft component, the cutting tool 5 can be used to perform chamfering operation on the edge of the inner hole, thereby realizing the movable chamfering operation. The chamfering depth can be adjusted by controlling the extension and retraction of the movable push rod 203, making it flexible and convenient to use.

[0044] The control mechanism 3 also includes an angle positioning rod 303 and an outer diameter positioning rod 304. The angle positioning rod 303 is rotatably connected to the inside of the rotary disk 301 along the axial direction, and the outer diameter positioning rod 304 is rotatably connected to the inside of the rotary disk 301 along the radial direction. Both the angle positioning rod 303 and the outer diameter positioning rod 304 are threaded rods. The angle positioning rod 303 is screwed into the inside of the control frame 302 through the rod body thread, and the outer diameter positioning rod 304 is screwed into the inside of the positioning frame 401 of one of the set of cutting mechanisms 4 through the rod body thread. In use, the rotational outer diameter of the three sets of cutting mechanisms 4 can be directly adjusted through the outer diameter positioning rod 304 to adapt to the inner hole of shaft parts with different hole diameters. As for the chamfer angle, the tilt angle of the cutting tool 5, i.e., the chamfer angle, can be adjusted only through the angle positioning rod 303.

[0045] The planing mechanism 4 also includes an angle connecting rod 403, with its two ends rotatably connected to the bottom of the planing tool holder 402 and the side of the driven block 405, respectively. During use, the angle positioning rod 303 can adjust the tilt angle of the planing tool 5, which is the chamfer angle during machining. The adjustment is flexible and convenient, requiring no replacement parts, simplifying the operation process and adapting to the machining of parts with different chamfering requirements. When the angle positioning rod 303 is rotated, it can drive the control frame 302 to move via the rod thread. The control frame 302 has a displacement groove 3021 radially arranged along the rotary disk 301 on its exterior, and a displacement rod 4061 is provided on the side of the driving block 406. The displacement rod 4061 is inserted into the displacement groove 3021. When the control frame 302 moves, the displacement groove 3021 can drive the driving block 406 to move together via the displacement rod 4061. The linkage rod 404 has a spiral-shaped active groove 4041 on its outside, and an active protrusion 4062 inside the active block 406. The active protrusion 4062 is inserted into the active groove 4041. When the active block 406 moves, the active protrusion 4062 can drive the linkage rod 404 to rotate through the active groove 4041. The driven block 405 has a driven protrusion 4051 inside, and the linkage rod 404 also has a spiral-shaped driven groove 4042 on its outside. The driven protrusion 4051 is inserted into the driven groove 4042. When the linkage rod 404 rotates, the driven groove 4042 can drive the driven block 405 to move through the driven protrusion 4051. Thus, when the driven block 405 moves, it can drive the planer holder 402 to rotate through the angle connecting rod 403 to change the operating angle. The change in the angle of the planer holder 402 changes the operating angle of the planer tool 5, that is, the chamfer angle, which is quick and convenient to adjust.

[0046] The control mechanism 3 also includes a synchronization disc 305, which is rotatably connected inside the rotary disc 301. A synchronization rod 4011 is located in the middle of the positioning frame 401, and the synchronization disc 305 has an arc-shaped synchronization groove 3051 inside. The synchronization rod 4011 is inserted into the synchronization groove 3051. During use, the initial outer diameter during chamfering can be adjusted via the outer diameter positioning rod 304, greatly reducing ineffective displacement and improving work efficiency. When the outer diameter positioning rod 304 is rotated, it can drive its mating parts through the rod's thread. The positioning frame 401 moves radially along the rotary disk 301. When the positioning frame 401 moves, the synchronizing rod 4011 can drive the synchronizing disk 305 to rotate through the synchronizing groove 3051. When the synchronizing disk 305 rotates, the cooperation of the other synchronizing grooves 3051 and the synchronizing rod 4011 can drive the other two sets of cutting mechanisms 4 to move synchronously and change the outer diameter. Thus, under the cooperation of the three sets of cutting mechanisms 4, the initial outer diameter of the chamfer can be adjusted, ensuring that the cutting tool 5 can quickly and effectively fit with the inner wall after being inserted into the hole to achieve the chamfering operation. The processing is stable and efficient.

[0047] The specific usage and function of this embodiment: In this invention, according to actual processing requirements, the chamfering angle and the initial chamfering outer diameter of the chamfering assembly are adjusted. The tilt angle of the cutting tool 5 can be adjusted through the angle positioning rod 303. The tilt angle of the cutting tool 5 is the chamfering angle during processing. The adjustment is flexible and convenient, without the need to change parts, simplifying the operation process. It can adapt to the processing of parts with different chamfering requirements. When the angle positioning rod 303 is rotated, the angle positioning rod 303 can drive the control frame 302 to move through the rod thread. When the control frame 302 moves, the displacement groove 3021 can move through the displacement rod 406. 1. The active block 406 moves synchronously. When the active block 406 moves, its active protrusion 4062 can drive the linkage rod 404 to rotate through the active groove 4041. When the linkage rod 404 rotates, the driven groove 4042 can drive the driven block 405 to move through the driven protrusion 4051. Thus, when the driven block 405 moves, it can drive the planer holder 402 to rotate through the angle connecting rod 403, changing the operating angle. The change in the angle of the planer holder 402 changes the operating angle of the planer tool 5, i.e., the chamfer angle. The initial outer diameter during chamfering can be adjusted through the outer diameter positioning rod 304, which can greatly reduce the amount of ineffective displacement and improve efficiency. In terms of working efficiency, when the outer diameter positioning rod 304 is rotated, the outer diameter positioning rod 304 can drive the positioning frame 401 that it is in sync with to move radially along the rotary disk 301 through the rod body thread. When the positioning frame 401 moves, the synchronizing rod 4011 can drive the synchronizing disk 305 to rotate through the synchronizing groove 3051. When the synchronizing disk 305 rotates, the cooperation of the other synchronizing grooves 3051 and the synchronizing rod 4011 can drive the other two sets of cutting mechanisms 4 to move synchronously to change the outer diameter of use. Thus, under the cooperation of the three sets of cutting mechanisms 4, the initial outer diameter of the chamfer can be adjusted, ensuring that the cutting tool 5 can quickly engage with the hole after being inserted into it. The inner wall is effectively fitted to achieve the chamfering operation. After adjustment, the shaft component is fixed to the top of the worktable 101 by the fixing block 102. The moving push rod 203 drives the moving seat 202 to move, and the drive motor 204 drives the spindle 301 to rotate. When the spindle 301 rotates, it can drive the three sets of cutting mechanisms 4 to rotate synchronously. When the cutting mechanism 4 moves with the moving seat 202 and extends into the edge of the inner hole of the shaft component, the cutting tool 5 can be used to perform the chamfering operation on the edge of the inner hole, thereby realizing the moving chamfering operation. The chamfering depth can be adjusted by controlling the extension and retraction of the moving push rod 203.
