Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, and in particular to a burr removal device for automotive nuts. Background Technology

[0002] Burr removal equipment for automotive nuts is one of the key pieces of equipment for ensuring nut quality and improving production efficiency. Burrs on mechanical parts can be caused by various factors, including plastic deformation during machining, flash from casting and forging, and weld residue. With increasing industrialization and automation, particularly in the aerospace and instrumentation sectors, the demand for precision in manufacturing mechanical parts and the miniaturization of mechanisms have made the harmful effects of burrs particularly apparent, gradually attracting widespread attention. These small burrs can affect the normal use of the nut.

[0003] The existing method of using an electromagnet to attract and fix the nut requires fixing the side of the nut with the electromagnet during attraction. This makes it impossible to grind one side of the nut, thus requiring a second deburring process and reducing the speed of deburring the nut.

[0004] An existing patent (publication number: CN219465698U) discloses a burr removal mechanism for preventing loosening nuts. It includes a C-shaped frame, with a deburring machine fixedly connected to the bottom surface of the horizontal frame of the C-shaped frame. A motor is fixedly connected to the right side of the right vertical frame of the C-shaped frame. The left end of the motor's rotating shaft extends to the right side of the left vertical frame of the C-shaped frame and is fixedly connected to a first circular plate. By rotating an L-shaped rod, it drives a disc and its side arc-shaped groove to rotate, causing three L-shaped strips to open outwards. This causes three clamping strips to open outwards simultaneously, fixing the inner wall of the nut to be ground, thus enabling rapid grinding of the outer side of the nut.

[0005] To address the aforementioned issues, while existing patents can fix the inner side of the nut to be ground, allowing for rapid grinding of the outer side, they can only process one nut at a time during deburring, resulting in low equipment production efficiency and hindering rapid nut processing. Summary of the Invention

[0006] The purpose of this utility model is to provide a burr removal device for machining automotive nuts, which can drive the outer shell of the device to rotate and grind and remove burrs from the workpiece inside. It can also process multiple nuts at once, improving processing efficiency. The auxiliary protrusions set inside the outer shell of the device can play an auxiliary role in deburring, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a burr removal device for machining automotive nuts, comprising a device housing, with support legs connected to both ends of the device housing, a drive mechanism for driving the device being provided inside one of the support legs, and an auxiliary mechanism for assisting in the processing of internal workpieces being provided on one side of the device housing.

[0008] The drive mechanism includes a drive motor, which is fixed inside a support leg by bolts. The drive motor's power output shaft is fixed with a drive wheel, and a belt is connected to the outer surface of the drive wheel. A driven wheel is connected to the upper end of the belt, and a reducer fixedly connected to the support leg is connected to one side of the driven wheel. A transmission rod fixedly connected to the equipment housing is fixed to the output end of the reducer.

[0009] Preferably, the outer surface of the equipment housing is hinged with a protective door, and the inner wall of the equipment housing is provided with a number of auxiliary protrusions.

[0010] Preferably, the auxiliary mechanism includes an internal gear ring, which is fixed to one side of the equipment housing, and a transmission gear meshes with the inner wall of the internal gear ring.

[0012] Preferably, a chain is engaged on the outer surface of the driving sprocket, and a driven sprocket is engaged at one end of the chain.

[0013] Preferably, the driven sprocket has an installation rod that penetrates the inner wall of the equipment housing fixed inside, and a plurality of stirring rods are fixed at equal intervals on the outer surface of the installation rod.

[0014] Preferably, the outer surface of the mounting rod is fitted with a protective sleeve that is fixedly connected to the equipment housing, and the protective sleeve is rotatably connected to the inside of the support leg through a bearing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The set drive mechanism can drive the equipment shell to rotate, grind and deburr the internal workpieces, and process multiple nuts at one time, improving processing efficiency. The auxiliary protrusions set inside the equipment shell can play an auxiliary role in deburring.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A burr removal device for machining automotive nuts includes a housing 1, with support legs 2 connected to both ends of the housing 1. One of the support legs 2 has a drive mechanism for driving the device inside, and an auxiliary mechanism for assisting in the processing of internal workpieces is provided on one side of the housing 1.

[0028] The drive mechanism includes a drive motor 3, which is fixed inside a support leg 2 by bolts. The power output shaft of the drive motor 3 is fixed with a drive wheel 31. A belt 32 is connected to the outer surface of the drive wheel 31. A driven wheel 33 is connected to the upper end of the belt 32. A reducer 34, which is fixedly connected to the support leg 2, is connected to one side of the driven wheel 33. A transmission rod 35, which is fixedly connected to the equipment housing 1, is fixed to the output end of the reducer 34. A protective door 4 is hinged to the outer surface of the equipment housing 1. Several auxiliary protrusions 6 are provided on the inner wall of the equipment housing 1.

[0029] By adopting the above technical solution, before using the deburring equipment for machining automotive nuts, the equipment housing 1 is first placed in a suitable position. The support legs 2 ensure the stability of the equipment. The protective door 4 on the equipment housing 1 is opened, and the workpiece to be deburred is poured into the equipment housing 1. Polishing materials, such as abrasives and chromium oxide powder, are added inside. Then the protective door 4 is closed. The drive motor 3 drives the drive wheel 31 to rotate, which causes the belt 32 to drive the driven wheel 33 to rotate, thereby driving the reducer 34 to run. The transmission rod 35 on the reducer 34 drives the equipment housing 1 to rotate, grinding and deburring the workpiece inside. Multiple nuts can be processed at once, improving processing efficiency. The auxiliary protrusions 6 set inside the equipment housing 1 can assist in deburring.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the auxiliary mechanism includes an internal gear ring 5, which is fixed to one side of the equipment housing 1. A transmission gear 51 is meshed on the inner wall of the internal gear ring 5. A connecting rod 52 is fixed inside the transmission gear 51. A drive sprocket 53 is fixed at the end of the connecting rod 52. A chain 54 is meshed on the outer surface of the drive sprocket 53. A driven sprocket 55 is meshed at one end of the chain 54. An installation rod 56 that penetrates the inner wall of the equipment housing 1 is fixed inside the driven sprocket 55. Several stirring rods 57 are fixed at equal intervals on the outer surface of the installation rod 56. A protective sleeve 58 that is fixedly connected to the equipment housing 1 is sleeved on the outer surface of the installation rod 56. The protective sleeve 58 is rotatably connected to the inside of the support leg 2 through a bearing.

[0031] By adopting the above technical solution, when the equipment shell 1 rotates, it will drive the internal gear ring 5, which in turn will mesh with the transmission gear 51 to rotate. Meanwhile, the connecting rod 52 drives the drive sprocket 53 to rotate. At this time, the chain 54 synchronously drives the driven sprocket 55 to rotate, which causes the mounting rod 56 to drive multiple stirring rods 57 to move, stirring the polishing material and workpiece inside the equipment shell 1. This ensures that the material and workpiece have more complete contact, improving the deburring effect. The protective sleeve 58 set on the equipment shell 1 can play a protective role, preventing the mounting rod 56 from shifting when rotating, and reducing the wear of the mounting rod 56.

[0032] Working principle: By pouring the workpiece to be deburred into the equipment housing 1 and adding polishing material, the protective door 4 is closed. The drive motor 3 drives the drive wheel 31 to rotate, which in turn drives the driven wheel 33 to rotate via the belt 32. This drives the reducer 34 to run. The transmission rod 35 on the reducer 34 drives the equipment housing 1 to rotate, grinding and deburring the workpiece inside. Multiple nuts can be processed at once. When the equipment housing 1 rotates, it drives the internal gear ring 5, which in turn meshes with the transmission gear 51 to rotate. The connecting rod 52 drives the drive sprocket 53 to rotate. At this time, the chain 54 synchronously drives the driven sprocket 55 to rotate, which causes the mounting rod 56 to drive multiple stirring rods 57 to move, stirring the polishing material and workpiece inside the equipment housing 1 to ensure more thorough contact between the material and the workpiece. The protective sleeve 58 on the equipment housing 1 provides protection.

[0033] 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 the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
