Description

Technical Field

[0001] This utility model relates to the technical field of deburring equipment, specifically to a deburring device for parts processing. Background Technology

[0002] Deburring is a crucial step in parts manufacturing. Burrs not only affect the appearance of parts but can also negatively impact subsequent assembly and use, such as reducing fit accuracy and increasing wear. Traditional deburring methods mainly include manual grinding and vibratory grinding. Manual grinding relies heavily on worker skills and experience, is inefficient, and struggles to guarantee consistent deburring quality. Furthermore, the dust and noise generated during manual grinding pose a health risk to workers.

[0003] While vibratory grinding improves deburring efficiency to some extent, it still presents several challenges. For example, vibratory grinding equipment is typically complex in structure and difficult to maintain, and insufficient contact between the workpiece and the grinding media during the grinding process leads to uneven deburring results. Furthermore, the abrasive and other media residues are difficult to remove from the workpiece surface, especially for workpieces with complex shapes and grooves, making cleaning even more challenging. To address these issues, this invention provides a deburring device for parts processing. Utility Model Content

The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0028] Refer to the instruction manual appendix Figure 1 To be continued Figure 4 As shown, this device achieves omnidirectional deburring of workpieces through the synergistic action of a rotary drive assembly and a workpiece placement tank assembly. The deburring device for parts processing includes a rotary drive assembly 1 and a workpiece placement tank assembly 2 mounted on its top surface. The rotary drive assembly 1 provides rotational power to the entire device, while the workpiece placement tank assembly 2 holds the workpiece to be processed and the diamond abrasive, and promotes full contact between the workpiece and the diamond abrasive through vibration during rotation.

[0029] The rotary drive assembly 1 includes a base 11, on the bottom surface of which three legs 12 are fixed in a circular array to provide stable support. A geared motor 13 is fixed on the left side of the inner cavity of the base 11. The bottom surface of the housing of the geared motor 13 is connected to the bottom surface of the inner cavity of the base 11 by screws. The top end of the output shaft of the geared motor 13 is connected to the center of the bottom surface of the placement groove 21 by a coupling, thereby transmitting the rotational power to the workpiece placement groove assembly 2.

[0030] The workpiece placement tank assembly 2 includes a placement tank 21 connected to the output shaft of the geared motor 13 via a coupling, and a screen 23 for holding the workpiece placed inside the placement tank 21. An opening is provided on the right side wall of the placement tank 21, and a diamond abrasive discharge port 22 is fixed inside the opening. One end face of the diamond abrasive discharge port 22 located inside the placement tank 21 is flush with the inner side wall of the placement tank 21 to facilitate the smooth discharge of diamond abrasive. A gate is provided at the outer end of the diamond abrasive discharge port 22 to control the discharge amount and time of diamond abrasive. A sealing cover 24 is locked to the upper end of the placement tank 21 via a latch to prevent workpieces and diamond abrasive from splashing out during rotation. The sealing cover 24 is also designed to be easy to open for placing and removing workpieces and cleaning the placement tank 21.

[0031] The workpiece placement screen 23 is the core component of the workpiece placement slot assembly 2. It includes a column 236 fixed in the center of the inner cavity of the placement slot 21, and a screen 231 threaded onto the outer surface of the column 236. Three protruding strips 237 are fixed in a circular array on the outer surface of the column 236 to increase the contact area with the screen 231 and improve its stability. A positioning hole 232, matching the column 236 and the protruding strips 237, is provided in the center of the screen 231 to ensure that the screen 231 is securely fitted onto the column 236. Inwardly recessed grooves 233 are provided on both the left and right sidewalls of the screen 231 for the small vibrating motor 234 to be fixed to both sides of the screen 231 with screws. The power cord of the small vibrating motor 234 is connected in parallel with the power cord of the geared motor 13 via an electric slip ring to provide power to the small vibrating motor 234 during rotation. Handles 235 are fixed symmetrically on the inner wall of the screen 231 to facilitate the operator to remove and place the screen 23 from the placement slot 21.

[0032] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0033] Under the condition that the electrical connections of the geared motor 13, the small vibratory motor 234 and the slip ring are normal and there is no looseness or damage, prepare the workpiece to be deburred and an appropriate amount of diamond abrasive. The workpiece should be cleaned and free of oil and impurities.

[0034] Unlock the latch at the top of the placement slot 21, open the sealing cover 24, and prepare to place the workpiece and diamond abrasive. Place the holding screen 23 onto the column 236 through the positioning hole 232 to secure the screen 231. Place the workpiece to be processed evenly inside the screen 231, then pour in an appropriate amount of diamond abrasive. The diamond abrasive should cover the surface of the workpiece, but not too much, to avoid affecting the rotation and vibration effects. Place the sealing cover 24 on the placement slot 21 and tighten the latch to prevent the workpiece and diamond abrasive from splashing out during rotation.

[0035] The geared motor 13 is started via the control panel or switch. The output shaft of the geared motor 13 drives the placement groove 21 to rotate through the coupling, thereby causing the workpiece and the diamond abrasive in the holding screen 23 to rotate in a circular motion. After the geared motor 13 starts, the small vibration motor 234 is connected in parallel with the power line of the geared motor 13 through the electric slip ring and also starts to work, shaking the screen 231 so that the workpiece and the diamond abrasive not only come into contact and grind during rotation, but also have the contact effect of jumping up and down and jumping left and right. Driven by the geared motor 13, the placement groove 21 and the holding screen 23 rotate together, while the small vibration motor 234 vibrates the screen 231. Under the dual action of rotation and vibration, the workpiece comes into full contact with the diamond abrasive, achieving all-round deburring treatment.

[0036] After the processing time is up, first turn off the small vibration motor 234, then turn off the reduction motor 13. Wait for the placement tank 21 and the holding screen 23 to stop rotating, unlock the latch, open the sealing cover 24, and prepare to remove the workpiece and clean the diamond grit. Use the handle 235 to remove the holding screen 23 from the placement tank 21, pour the deburred workpiece out of the screen 231 and collect it. Open the gate of the diamond grit discharge port 22 to discharge the diamond grit in the placement tank 21 and collect it for the next use. At the same time, clean the residual diamond grit and impurities in the placement tank 21 and the holding screen 23.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
