Description

Technical Field

[0001] This application relates to the field of metal processing, and in particular to a deburring and chamfering device. Background Technology

[0002] Deburring and chamfering of metal workpieces are essential steps in the metal processing workflow. In existing deburring and chamfering machines, the grinding mechanism typically includes multiple grinding motors and grinding drills, with each motor and drill corresponding to a different workpiece for deburring and chamfering.

[0015] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0016] like Figures 1 to 3 As shown, one embodiment provides a deburring and chamfering device, which includes: a base 100, a movable worktable 200, and a chamfering mechanism 300.

[0017] A base 100; a movable worktable 200 is mounted on the base 100; a chamfering mechanism 300 includes a support 310, a lifting assembly 320, and a grinding assembly 330. The support 310 is located on one side of the movable worktable 200, the lifting assembly 320 is located on the support 310, and the grinding assembly 330 is located on the lifting assembly 320, corresponding to the movable worktable 200; the grinding assembly 330 includes a grinding motor 331, a drive wheel 332, a grinding unit 333, a driven wheel 334, a first belt 335, and a second belt 336. All elements 333 are mounted on the lifting assembly 320. There are six grinding units 333 arranged at intervals. Three adjacent grinding units 333 form a grinding group. The driving wheel 332 is mounted on the output end of the grinding motor 331. The number of driven wheels 334 corresponds one-to-one with the number of grinding units 333. The driven wheels 334 are mounted on the grinding units 333. There are two first belts 335, which are connected between the driving wheel 332 and one driven wheel 334 in the grinding group. There are four second belts 336, which are connected between two driven wheels 334 in the same grinding group.

[0018] The lifting assembly 320 may include a motor, a lead screw drive mechanism, and a moving base. Since the lifting assembly 320 is prior art, it is not specifically limited here.

[0019] In this embodiment, during operation, the workpiece is placed on a mold, which is then placed on and fixed on a movable worktable 200. The movable worktable 200 moves the workpiece directly below the grinding assembly 330, adjusting the relative position between the workpiece and the grinding assembly 330. The lifting assembly 320 on the support base 310 drives the grinding assembly 330 to rise and fall as a whole, aligning the drill bit 3336 of the grinding assembly 330 with the position on the workpiece where deburring or chamfering is required.

[0020] The grinding motor 331 starts, and its output drives the drive wheel 332 to rotate. The drive wheel 332 drives the first driven wheel 334 in each of the two grinding groups to rotate via two first belts 335. Within the same grinding group, the first driven wheel 334 drives the other two driven wheels 334 to rotate sequentially via a second belt 336, thereby causing the six grinding units 333 to rotate synchronously. The rotating grinding units 333 contact the workpiece to complete deburring or chamfering. During the processing, the movable worktable 200 can be used to adjust the workpiece position to achieve multi-position processing.

[0021] This device synchronously controls multiple grinding units 333 via a single grinding motor 331, enabling simultaneous deburring or chamfering of edges and holes on multiple workpieces, significantly improving processing efficiency. The transmission structure, consisting of a drive pulley 332, a first belt 335, a driven pulley 334, and a second belt 336, ensures smooth transmission and a compact structure, avoiding the complex layout of multi-motor drives and reducing equipment size and cost. The grinding assembly 330 can be height-adjusted via a lifting assembly 320, and the horizontal position of the workpiece can be adjusted using a movable worktable 200, adapting to workpieces of different thicknesses or sizes, offering high flexibility.

[0022] like Figures 1 to 3 As shown, in some embodiments, the drive pulley 332 is provided with a plurality of first grooves that cooperate with the first belt 335 at intervals.

[0023] When the grinding motor 331 drives the drive wheel 332 to rotate, the two first belts 335 are respectively embedded in the corresponding first grooves on the drive wheel 332, rotating synchronously with the drive wheel 332 and driving the driven wheel 334 in the grinding assembly to rotate. In this way, the cooperation between the first groove and the first belt 335 increases the contact area and friction between the belt and the drive wheel 332, effectively preventing belt slippage during transmission, ensuring that the power of the drive wheel 332 is stably transmitted to the grinding assembly, ensuring that the rotation speed of each grinding unit 333 is consistent, and improving machining accuracy and stability.

[0024] like Figures 1 to 3As shown, in some embodiments, the driven wheel 334 is provided with a plurality of second grooves that cooperate with the second belt 336 at intervals.

[0025] Within the same grinding unit, when the driven wheel 334 is driven by the second belt 336, the second belt 336 is embedded in the second groove on the driven wheel 334, rotating synchronously with the driven wheel 334 and driving the next driven wheel 334 to rotate. The cooperation between the second groove and the second belt 336 avoids slippage or offset of the belt drive within the same grinding unit, ensuring the synchronous rotation speed of the three grinding units 333 and ensuring consistent chamfering or deburring effects.

[0026] like Figures 1 to 3 As shown, in some embodiments, the grinding unit 333 includes a mounting base 3331, a bearing assembly, a rotating shaft 3332, a movable sleeve 3333, a cylindrical pin 3334, a spring 3335, and a drill bit 3336. The mounting base 3331 is disposed on the lifting assembly 320, the bearing assembly is installed in the mounting base 3331, the rotating shaft 3332 passes through the bearing assembly, the movable sleeve 3333 is movably sleeved on the rotating shaft 3332 through the cylindrical pin 3334, the spring 3335 is disposed between the rotating shaft 3332 and the movable sleeve 3333, and the drill bit 3336 is sleeved on the movable sleeve 3333.

[0027] When the grinding unit 333 is working, the rotating shaft 3332 rotates stably under the support of the bearing assembly, driving the drill bit 3336 to rotate synchronously via the movable sleeve 3333. When the drill bit 3336 contacts the workpiece, the workpiece generates a reaction force on the drill bit 3336. The movable sleeve 3333 compresses the spring 3335 and moves axially along the rotating shaft 3332 via the cylindrical pin 3334, buffering the impact force at the moment of contact. After machining is completed, the spring 3335 returns to its original position, and the movable sleeve 3333 drives the drill bit 3336 back to its original position. In this way, the cooperation between the spring 3335 and the movable sleeve 3333 forms an elastic buffer structure, avoiding damage to the workpiece surface or breakage of the drill bit 3336 caused by hard contact between the drill bit 3336 and the workpiece, thus extending the service life of the drill bit 3336.

[0028] like Figures 1 to 3 As shown, in some embodiments, the rotating shaft 3332 has a waist-shaped groove 3337, and the movable sleeve 3333 has two oppositely arranged through holes 3338. The cylindrical pin 3334 passes through the waist-shaped groove 3337 and the two through holes 3338.

[0029] A waist-shaped groove 3337 is provided on the rotating shaft 3332. In this embodiment, the two openings of the waist-shaped groove 3337 are arranged radially along the rotating shaft 3332. And the length direction of the opening of the waist-shaped groove 3337 is arranged axially along the rotating shaft 3332.

[0030] When the movable sleeve 3333 moves axially along the rotating shaft 3332 under impact, the cylindrical pin 3334 slides within the waist-shaped groove 3337 of the rotating shaft 3332, thus enabling the movable sleeve 3333 to move. The length of the waist-shaped groove 3337 determines the maximum travel of the movable sleeve 3333, preventing the movable sleeve 3333 from moving excessively and detaching from the rotating shaft 3332.

[0031] like Figures 1 to 3 As shown, in some embodiments, the mobile worktable 200 includes a first linear drive assembly 210, a second linear drive assembly 220, a base 230, a positioning assembly 240, and a material fixing assembly 250. The first linear drive assembly 210 is disposed on the base 100, and the second linear drive assembly 220 is disposed on the output end of the first linear drive assembly 210. The movement direction of the output end of the second linear drive assembly 220 is perpendicular to the movement direction of the output end of the first linear drive assembly 210. The base 230 is mounted on the output end of the second linear drive assembly 220. The positioning assembly 240 and the material fixing assembly 250 are both disposed on the base 230. The positioning assembly 240 is used to fix the mold, and the material fixing assembly 250 is used to fix the processed parts on the mold.

[0032] The mold is fixed to the base 230 by the positioning component 240, and the workpiece to be processed is fixed to the mold by the material fixing component 250. The first linear drive component 210 drives the base 230 to move in the second direction, and the second linear drive component 220 drives the base 230 to move in the first direction, thereby adjusting the horizontal position of the workpiece so that the part of the workpiece to be processed is precisely aligned with the grinding component 330.

[0033] It is understandable that the first direction corresponds to the X-axis (i.e., the left-right direction) of the spatial coordinate system, the second direction corresponds to the Y-axis (i.e., the front-back direction) of the spatial coordinate system, and the third direction corresponds to the Z-axis (i.e., the up-down direction) of the spatial coordinate system.

[0034] It is worth noting that the first linear drive assembly 210 and the second linear drive assembly 220 have the same structure. The first linear drive assembly 210 may include a motor, a lead screw transmission mechanism, and a moving base. Since the first linear drive assembly 210 is prior art, it is not specifically limited here.

[0035] The positioning assembly 240 may include a positioning cylinder and a positioning element. The positioning cylinder is fixed on the base 230, and the positioning element is connected to the output end of the positioning cylinder. When the mold is placed on the base 230, the positioning cylinder is activated, driving the positioning element to move downward, so that the positioning element presses against the edge of the mold.

[0036] The material-fixing assembly 250 may include a material-fixing cylinder, a connecting rod mechanism, and material-fixing components. The material-fixing cylinder is mounted at an angle on the base 230. Multiple material-fixing components are provided, each connected to the output end of the material-fixing cylinder via the connecting rod mechanism. Each material-fixing component has a material-fixing groove for adhering to the workpiece. Before processing, the material-fixing cylinder drives the connecting rod mechanism to ensure that the multiple material-fixing components adhere to their respective workpieces, thereby preventing the workpiece from wobbling during processing.
