Description

Chamfering device

Technical Field

The utility model relates to the technical field of machining, in particular to a chamfering device.

Background

It is known that machined products or other products such as injection molded products may have sharp corners and may easily scratch a person's hand after the machining is completed, and thus the sharp corners need to be machined to form rounded corners during the machining, thereby avoiding injury to the person.

For the sensor product, the problem that the sharp edge of the sensor can scratch the hand is not considered when the manufacturer initially designs the sensor, for example, the edge of the shell of the sensor is sharp, and the sensor is inconvenient to install and use for customers. To address this problem, many manufacturers use manual die cutting to eliminate the sharp edges of the sensor. However, the quality of the product processed by the manual die cutting mode is low, the consistency is poor, and the efficiency is low.

In addition, some manufacturers are also considering reworking product production molds to machine sensor products having rounded edges. However, the manufacturer re-opens the mold and requires all adjustments to the design of the entire sensor product, which is expensive and costly.

Therefore, it is necessary to provide a chamfering device for overcoming the above-mentioned drawbacks of the prior art.

In one embodiment of the present utility model, referring to fig. 1-4b, there is provided a chamfering apparatus 100 comprising a motor 10, a chamfering blade 30 driven to rotate by the motor 10, and a work table 40 for placing a work piece 90 to be chamfered, wherein a chute 42 for allowing the work piece 90 to be chamfered to slide therein is formed on the work table 40, a chamfering window 462 is formed at the bottom of the chute 42, and the chamfering blade 30 is disposed to extend into the chamfering window 462 and interfere with the work piece 90 to be chamfered, thereby chamfering the edge of the work piece 90 to be chamfered.

In the chamfering device provided by the utility model, since the chamfering blade extends into the chamfering window and protrudes from the chamfering window, when a product to be chamfered such as a sensor housing is placed into the chute and slid along the chute, the corner of the sensor housing is in contact with the chamfering blade, and the chamfering blade rotating at a high speed cuts out a part of the material of the corner portion, thereby forming a rounded corner shape at the corner portion. The chamfering device has the advantages of simple structure, convenient operation and low cost, and is worth popularizing.

In one embodiment, the workpiece table 40 has a bottom wall 46 and side plates 44 disposed on two sides of the bottom wall 46, and the bottom wall 46 and the two side plates 44 together define the chute 42. The chute 42 may also be formed by forming a recess in the workpiece table 40 on both sides equivalent to the side plates and bottom equivalent to the bottom wall. Preferably, the chamfer window 462 is formed in both the side plate 44 and the bottom wall 46, and the chamfer cutter 30 is disposed to extend into the chamfer window 462 and protrude upward from the bottom wall 46. When the operator places the workpiece 90 in the chute 42, the operator slowly pushes the workpiece 90 in the chute 42 by means of a tool or by hand, and in the process of pushing the workpiece 90, the edge angle of the edge of the workpiece 90 interferes with the chamfering blade 30 extending from the chamfering window 462, and the chamfering blade 30 rotating at a high speed cuts away part of the material of the edge angle along with the rotation, so that a fillet structure is formed at the edge angle position, and finally, the purpose of chamfering the outer shell of the workpiece 90 such as a sensor is achieved.

Preferably, each of the side plates 44 is provided with a guide surface 442 along the end of the sliding direction of the work to be chamfered 90. The distance between the two guide surfaces 442 is greater than the distance between the rest of the two side plates 44, thus corresponding to the formation of an open structure at the guide surfaces 442, which facilitates easy handling of the workpiece by the operator after chamfering the workpiece, and removal of the chamfered workpiece.

Preferably, the motor 10 has a motor base 12 and an output shaft 14 disposed on the motor base 12, and a cutter shaft 20 is disposed between the output shaft 14 and the chamfering tool 30. In other words, one end of the arbor 20 is fixedly connected to the output shaft 14, and the other end is fixedly connected to the chamfering tool 30. When the motor is energized, a motor assembly (not shown) inside the motor housing 12 starts to operate, thereby driving the output shaft 14 to rotate, and the cutter shaft 20 and the chamfer cutter 30 fixedly connected with the output shaft 14 synchronously rotate at a high speed, thereby realizing power transmission through the above-mentioned connection structure.

Preferably, the motor base 12 is mounted on the side wall 52 of the mounting base 50, the output shaft 14, the cutter shaft 20 and the chamfering cutter 30 are arranged in the cavity 54, and the chamfering cutter 30 penetrates through the cavity 54 and stretches into the chamfering window 462. Through the mounting seat 50, the motor seat 12 can be stably fixed on the mounting seat 50, and the whole power transmission system (comprising the motor 10, the cutter shaft 20 and the chamfering cutter 30) is enabled to run more stably, so that a high-quality chamfering effect is realized, and bad flaws such as burrs and the like at the edge angle of the workpiece 90 are avoided.

In one embodiment, the chamfering device 100 may further include a base 60, and the mount 50 and the work table 40 are disposed on the base 60. The provision of the base 60 allows the entire chamfer structure (i.e., the motor 10, arbor 20, chamfer cutter 30, and mounting base 50) to be formed as a stronger whole.

Further, a slit 464 that extends in the sliding direction of the work to be chamfered 90 and penetrates the bottom wall 46 in the thickness direction of the bottom wall 46 is formed in the bottom wall 46, the slit 464 being provided such that the relative width of the two side plates 44 is adjustable. The provision of the slit 464 divides the entire chute 42 into two parts, so that by adjusting the relative position between the two parts, adjustment of the distance between the two side plates 44 is achieved. This means that workpieces of different sizes, such as sensors, can be placed into the chute 42 for the purpose of chamfering products of different sizes.

To facilitate the operator's handling of the chamfering device 100, a bracket 70 supporting the base 60 may be further included. The bracket 70 is provided to increase the height of the entire chamfering device, thereby enabling an operator to stand more comfortably.

To avoid operator injury due to flying out of material chips from the high speed cutting of the chamfer cutter 30, a cover plate 80 may be provided over the cavity 54.

It is conceivable that in order to achieve more efficient chamfering operation, for example, chamfering the corners on both sides of the workpiece 90 at the same time, two sets of chamfering structures may be provided, for example, corresponding chamfering structures (such as the motor, the arbor, the chamfering blade and the corresponding mounting seat described above) are symmetrically provided on both sides of the two side plates 44, so that chamfering operation can be performed on the corners on both sides of the workpiece at the same time, which greatly increases the operation speed.

Those of skill in the art will appreciate that the various operations, methods, steps in the flow, acts, schemes, and alternatives discussed in the present application may be alternated, altered, combined, or eliminated. Further, other steps, means, or steps in a process having various operations, methods, or procedures discussed herein may be alternated, altered, rearranged, disassembled, combined, or eliminated. Further, steps, measures, schemes in the prior art with various operations, methods, flows disclosed in the present application may also be alternated, altered, rearranged, decomposed, combined, or deleted.

The foregoing is only a partial embodiment of the present application, and it should be noted that it will be apparent to those skilled in the art that modifications and adaptations can be made without departing from the principles of the present application, and such modifications and adaptations are intended to be comprehended within the scope of the present application.
