Technical Field
[0001] The utility model relates to the technical field of mechanical processing, and more specifically to a chamfering device. Background Art
[0002] As we all know, machined products or other products such as injection molded products may have sharp edges and corners after processing, which can easily scratch people's hands. Therefore, these sharp edges and corners need to be cut during processing so that they can be rounded to avoid causing harm to people.
[0003] For sensor products, manufacturers did not consider the problem of sharp edges that may cause scratches when initially designing sensors. For example, the edges of the sensor shell are relatively sharp, which is inconvenient for customers to install and use. To solve this problem, many manufacturers use manual die-cutting to eliminate the sharp edges of the sensor. However, the quality of products processed by this manual die-cutting method is relatively low, the consistency is poor, and the efficiency is low.
[0004] In addition, some manufacturers are also considering re-processing product production molds to process sensor products with rounded edges. However, manufacturers need to adjust the design of the entire sensor product to re-open the mold, which is expensive and costly.
[0005] Therefore, the industry needs to provide a chamfering device to overcome the above-mentioned defects of the prior art. Utility Model Content
[0006] The purpose of the utility model is to solve the above problem and provide a chamfering device.
[0007] In order to meet the purpose of the utility model, the utility model adopts the following technical solutions:
[0008] A chamfering device comprises: a motor, a chamfering tool driven to rotate by the motor, and a workpiece table for placing a workpiece to be chamfered, a slide groove for allowing the workpiece to be chamfered to slide therein is formed on the workpiece table, a chamfering window is formed at the bottom of the slide groove, and the chamfering tool is configured to extend into the chamfering window and interfere with the workpiece to be chamfered, thereby chamfering the edge of the workpiece to be chamfered.
[0009] Preferably, the workpiece platform has a bottom wall and side panels arranged on both sides of the bottom wall, and the bottom wall and the two side panels jointly define the slide groove.
[0010] Preferably, the chamfered window is formed jointly on at least one side plate and the bottom wall; and the chamfering knife is arranged to extend into the chamfered window and protrude upward from the bottom wall.

[0014] Preferably, it further comprises a base, and the mounting seat and the workpiece table are arranged on the base.
[0015] Preferably, a gap is formed on the bottom wall, extending along the sliding direction of the workpiece to be chamfered and penetrating the bottom wall in the thickness direction of the bottom wall, and the gap is arranged so that the relative width of the two side walls is adjustable.

[0016] Compared with the prior art, the beneficial technical effects of the utility model are as follows:
[0017] In the chamfering device provided by the utility model, the inverting device includes a motor, a chamfering knife driven to rotate by the motor, and a workpiece table for placing the workpiece to be chamfered. A slide groove is formed on the workpiece table for the workpiece to be chamfered to slide therein, and a chamfering window is formed at the bottom of the slide groove, and the chamfering knife is configured to extend into the chamfering window.

[0029] In one embodiment of the present invention, reference Figure 1-4b , a chamfering device 100 is provided, comprising: a motor 10, a chamfering tool 30 driven to rotate by the motor 10, and a workpiece table 40 for placing a workpiece 90 to be chamfered, characterized in that: a slide groove 42 is formed on the workpiece table 40 for allowing the workpiece 90 to be chamfered to slide therein, and a chamfering window 462 is formed at the bottom of the slide groove 42, and the chamfering tool 30 is configured to extend into the chamfering window 462 and interfere with the workpiece 90 to be chamfered, thereby chamfering the edge of the workpiece 90 to be chamfered.
[0030] In the chamfering device provided by the utility model, since the chamfering knife extends into the chamfering window and protrudes from the chamfering window, when a product to be chamfered, such as a sensor housing, is placed in the slide slot and slides along the slide slot, the corner of the sensor housing contacts the chamfering knife, and the high-speed rotating chamfering knife cuts off a part of the material at the corner, thereby forming a rounded shape at the corner. This chamfering device has a simple structure, is easy to operate, and is low in cost, and is worthy of promotion.
[0031] In one embodiment, the workpiece platform 40 has a bottom wall 46 and side panels 44 disposed on both sides of the bottom wall 46, and the bottom wall 46 and the two side panels 44 jointly define the slide groove 42. The slide groove 42 can also be formed in this way: a groove is formed on the workpiece platform 40, the two sides of the groove are equivalent to the above-mentioned side panels, and the bottom of the groove is equivalent to the bottom wall. Preferably, the chamfer window 462 is jointly formed on the side panels 44 and the bottom wall 46; the chamfering knife 30 is configured to extend into the chamfer window 462 and protrude upward from the bottom wall 46. After the operator places the workpiece 90 into the slide groove 42, the operator slowly pushes the workpiece 90 in the slide groove 42 with the help of tools or by hand. In the process of pushing the workpiece 90, the edges of the workpiece 90 interfere with the chamfering tool 30 extending from the chamfering window 462. The high-speed rotating chamfering tool 30 cuts off part of the material at the edges as it rotates, thereby forming a rounded corner structure at the edges, and finally achieving the purpose of chamfering the workpiece 90, such as the housing of a sensor.
[0032] Preferably, each of the side plates 44 is provided with a guide surface 442 at the end along the sliding direction of the workpiece 90 to be chamfered. The distance between the two guide surfaces 442 is larger than the distance between the other parts of the two side plates 44, so it is equivalent to forming an open structure at the guide surface 442, which is conducive to the operator to easily hold the workpiece after chamfering the workpiece, and then take away the chamfered workpiece.
[0033] Preferably, the motor 10 has a motor base 12 and an output shaft 14 disposed on the motor base 12; a knife shaft 20 is disposed between the output shaft 14 and the chamfering knife 30. In other words, one end of the knife shaft 20 is fixedly connected to the output shaft 14, and the other end is fixedly connected to the chamfering knife 30. When the motor is powered on, the motor assembly (not shown) inside the motor base 12 starts to operate, thereby driving the output shaft 14 to rotate, and the knife shaft 20 and the chamfering knife 30 fixedly connected to the output shaft 14 rotate synchronously at high speed, thereby realizing power transmission through the above-mentioned connection structure.
[0034] Preferably, it further comprises a mounting seat 50 with a cavity 54 formed therein; the motor seat 12 is mounted on the side wall 52 of the mounting seat 50; the output shaft 14, the blade shaft 20 and the chamfering knife 30 are arranged in the cavity 54; the chamfering knife 30 passes through the cavity 54 and extends 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 entire power transmission system (composed of the motor 10, the blade shaft 20 and the chamfering knife 30) can run more smoothly, thereby achieving a high-quality chamfering effect and avoiding burrs and other undesirable defects at the edges and corners of the workpiece 90.
[0035] In one embodiment, the chamfering device 100 may further include a base 60, and the mounting base 50 and the workpiece table 40 are disposed on the base 60. Providing the base 60 can make the entire chamfering structure (that is, the motor 10, the cutter shaft 20, the chamfering cutter 30 and the mounting base 50) form a more solid whole.
[0036] In addition, a slit 464 is formed on the bottom wall 46, extending along the sliding direction of the workpiece 90 to be chamfered and penetrating the bottom wall 46 in the thickness direction of the bottom wall 46. The slit 464 is configured to make the relative width of the two side plates 44 adjustable. The slit 464 can be provided to divide the entire chute 42 into two parts, so that by adjusting the relative position between the two parts, the distance between the two side plates 44 can be adjusted. This means that workpieces of different sizes, such as sensors, can be placed in the chute 42, thereby achieving the purpose of chamfering products of different sizes.
[0037] In order to facilitate the operator to operate the chamfering device 100, a bracket 70 may be further included to support the base 60. The bracket 70 may be provided to increase the height of the entire chamfering device, thereby allowing the operator to operate more comfortably while standing.
[0038] In order to prevent material debris generated by high-speed cutting of the chamfering cutter 30 from flying out and causing harm to the operator, a cover plate 80 may be provided on the cavity 54 .
[0039] It can be imagined that: in order to achieve more efficient chamfering operations, such as chamfering the edges and corners on both sides of the workpiece 90 at the same time, two sets of chamfering structures can be set, such as symmetrically setting corresponding chamfering structures (such as the above-mentioned motor, tool shaft, chamfering tool and corresponding mounting seat) on both sides of the two side plates 44, so that the edges and corners on both sides of the workpiece can be chamfered at the same time, which greatly improves the operation speed.
[0040] Those skilled in the art will appreciate that the various operations, methods, steps, measures, and schemes in the processes discussed in this application may be alternated, altered, combined, or deleted. Further, other steps, measures, and schemes in the various operations, methods, and processes discussed in this application may also be alternated, altered, rearranged, decomposed, combined, or deleted. Further, the steps, measures, and schemes in the prior art that are similar to those disclosed in this application may also be alternated, altered, rearranged, decomposed, combined, or deleted.
[0041] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
