Description

Technical Field

[0001] The utility model relates to a chamfering device, in particular to an automatic chamfering tool for bars. Background Art

[0002] In the field of machining, bar chamfering is a crucial process, crucial for improving part quality, aesthetics, and the smooth execution of subsequent processing. Traditional bar chamfering relies on manual labor or simple mechanical equipment, which suffers from low efficiency, low precision, complex operation, and high labor intensity. Especially in high-volume production scenarios, manual or low-precision mechanical equipment cannot meet the stringent requirements for product consistency, production efficiency, and cost control.

[0003] Specifically, manual chamfering is easily affected by factors such as the operator's skill level and fatigue, resulting in inconsistent chamfer dimensions and poor roundness. Simple mechanical equipment often lacks the flexibility to adapt to different bar specifications, nor can it guarantee bar stability and machining accuracy during high-speed machining. Furthermore, traditional loading methods often require manual intervention, increasing production costs and labor intensity while reducing production efficiency. Utility Model Content

[0004] The utility model aims to provide an automatic chamfering tool for bars, so as to improve the automation of bar chamfering.

[0005] The utility model is realized by adopting the following technical scheme: an automatic chamfering tool for rods, characterized in that it includes a toothed disc, a baffle, a chamfering grinding wheel and an automatic feeding device, the toothed disc is provided with a plurality of grooves for placing rods, the baffle is arranged on the outside of the rotating surface of the toothed disc, the toothed disc and the chamfering grinding wheel are coaxially arranged, and the automatic feeding device is arranged on one side of the baffle.

[0006] Furthermore, the toothed disc includes an angle disc and a rubber-coated disc, and the rubber-coated disc is fixed on the motor and rotates with the motor; the angle disc is provided with a plurality of grooves for placing rods, and the width and depth of the grooves are designed according to the diameter and length of the rods to ensure that the rods will not loosen during rotation and can achieve effective rolling.

[0007] Furthermore, the baffle includes a grinding baffle and a loading baffle. The grinding baffle and the loading baffle are arranged on both sides of the chainring. A gap is left between the grinding baffle and the chainring so that the rod on the chainring contacts the grinding baffle and the chainring at the same time. The grinding baffle is used to provide the necessary friction during the rotation of the rod, so that the rod rolls along its own axis in the groove; the loading baffle provides an installation position for the automatic loading device.

[0008] Furthermore, the baffle also includes a positioning baffle, which is arranged on the grinding baffle along the radial direction of the chainring and gradually becomes thicker along the rotation direction of the chainring, and is used to adjust the longitudinal position of the rod in the groove.

[0009] Furthermore, the chamfering grinding wheel has a chamfering grinding surface with an adjustable angle, which is used to chamfer the rotating rod. By adjusting the position and angle of the chamfering grinding wheel, the width and angle of the chamfer can be controlled.

[0010] Furthermore, the automatic loading device includes a sensor and a push rod device. The automatic loading device is arranged on the loading baffle, and the outlet of the automatic loading device is facing the chainring. The sensor is used to detect whether the rod reaches the specified position. When the rod is detected, the push rod device is started to push the rod into the groove of the chainring to realize automatic loading.

[0011] Furthermore, the groove depth of the angle plate is smaller than the diameter of the rod but larger than its radius, so that the rod is in contact with the chainring and the baffle at the same time.

[0012] The automatic chamfering tool for bars described in the utility model has the following beneficial effects:

[0013] Improved Processing Precision: The cleverly designed chainring and baffle combination ensures stable rotation and uniform rolling of the bar during processing, ensuring consistent roundness and width of the chamfer. The chainring thickness and slot width can be flexibly adjusted to suit the bar size, further enhancing processing precision and applicability.

[0014] Improved production efficiency: The design of the automated loading device enables automatic feeding and precise positioning of the bars, significantly reducing manual intervention and improving production efficiency. At the same time, the continuous drive of the motor ensures the continuity and efficiency of the chamfering process.

[0015] Reduce labor intensity: Due to the realization of automatic loading and stable processing, operators only need to monitor and maintain the equipment and do not need to directly participate in physical labor, which effectively reduces labor intensity.

[0016] Enhanced equipment applicability: This device is suitable for chamfering of bars of various specifications. By adjusting the relevant parameters of the toothed disc and the grinding wheel, it can achieve flexible processing of bars of different diameters and lengths, thereby improving the versatility and utilization rate of the equipment.

[0017] Control processing costs: Automated, high-precision processing methods help reduce material waste and defective products, while improving production efficiency and equipment utilization efficiency, thereby helping to reduce overall processing costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0027] like Figure 1-5As shown, an automatic chamfering tool for bars includes a crankset 100, a baffle 200, a chamfering grinding wheel 300, and an automatic loading device 400. The crankset 100 and the chamfering grinding wheel 300 are coaxially arranged, the baffle 200 is arranged outside the rotating surface of the crankset 100, and the automatic loading device 400 is arranged on one side of the baffle 200.

[0028] The crankset 100 consists of an angle disc 101 and a rubber-coated disc 102. The rubber-coated disc 102 is fixed to the motor and rotates with the motor. The angle disc 101 is provided with multiple slots for accommodating rods. The width and depth of the slots are designed according to the diameter and length of the rods. The depth of the slots should be less than the rod diameter but greater than its radius. This ensures that the chamfered rod 001 contacts both the crankset 100 and the baffle 200 simultaneously, ensuring that the rod does not loosen during rotation and can effectively roll.

[0029] The baffle 200 includes a grinding baffle 201, a feeding baffle 202 and a positioning baffle 203. The grinding baffle 201 and the feeding baffle 202 are respectively arranged on both sides of the chainring 100, and the positioning baffle 203 is arranged on the grinding baffle 201 along the radial direction of the chainring 100. The positioning baffle 203 gradually becomes thicker along the rotation direction of the chainring 100. The grinding baffle 201 is used to provide the necessary friction during the rotation of the rod, so that the rod rolls in the diameter direction in the groove to ensure the roundness of the chamfer. The feeding baffle 202 provides an installation position for the automatic feeding device. The positioning baffle 203 is used to adjust the longitudinal position of the rod in the groove to ensure the consistency of the chamfer width.

[0030] The chamfering grinding wheel 300 has a chamfering grinding surface 301, the angle of which is adjustable, for chamfering the rotating bar. By adjusting the position and angle of the chamfering grinding wheel, the width and angle of the chamfer can be controlled.

[0031] The automatic loading device 400 includes a sensor 401 and a push rod device 402. The automatic loading device 400 is installed on the loading baffle 202, and the outlet of the automatic loading device 400 is directly opposite the chainring 100. The sensor 401 is used to detect whether the bar has reached the specified position. When the bar is detected, the push rod device 402 is activated to push the bar 002 being automatically loaded into the groove of the chainring 100, thereby realizing automatic loading.

[0032] After loading is completed, the rod enters the gap between the grinding baffle 201 and the chainring 100 along with the chainring 100, and the rod on the chainring 100 is aligned by the positioning baffle 203, and then the rod is rotated around its own axis by the friction of the grinding baffle 201. At the same time, the rod rotates around the axis of the chainring 100 as a whole under the drive of the chainring 100. In this process, the surface to be chamfered of the rod contacts the chamfering grinding surface 301 of the chamfering grinding wheel 300 to complete the chamfering. After chamfering is completed, the rod moves to the lower end of the chainring 100 and falls off naturally to complete the unloading.

[0033] The above embodiments describe the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Without departing from the spirit and scope of the present invention, modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the scope of protection of the appended claims.
