Description

Double-sided chamfering device

Technical Field

The utility model relates to the technical field of chamfering devices, in particular to a double-sided chamfering device.

Background Art

Chamfering is to remove burrs on parts caused by machining, so that the product is not sharp and will not cut the user. It is also for the convenience of parts assembly. Generally, chamfering is required on the inner circle of the parts. Chamfering machine is a small precision machine tool professionally used for chamfering of mold manufacturing, hardware machinery, machine tool manufacturing, hydraulic parts, valve manufacturing, textile machinery, and removing burrs of products processed by milling and planing. The use of fast machine chamfering is the development trend of the machinery industry.

After searching, Chinese patent publication number CN219787716U discloses a double-sided chamfering device for a bushing, which includes a processing table, which is fixedly connected to a grinding mechanism, which is slidably connected to a clamping mechanism, which is fixedly connected to a first driving member for driving the clamping mechanism to slide toward or away from the grinding mechanism, which is slidably connected to a fixed block for the bushing to be clamped, which is fixedly connected to a second driving member for driving the fixed block to slide toward or away from the clamping mechanism, which is slidably connected to a positioning block for plugging with an oil hole, which is slidably connected to the fixed block, and which is provided with a slide groove for the positioning block to be clamped and slide, and the positioning block and the fixed block are connected by a first elastic member. The device drives the bushing to move the positioning block toward the direction close to the first elastic member. When the positioning block is aligned with the oil hole, the first elastic member forces the positioning block to move toward the direction close to the oil hole until the positioning block protrudes out of the oil hole, thereby improving the stability of the bushing placement. The device can only chamfer one type of bushing, and its practicality needs to be improved. In the prior art, when chamfering a cylindrical workpiece, the cylindrical workpiece will be subjected to forces in all directions, and it is necessary to avoid the workpiece from shifting. In addition, for workpieces of different diameters and lengths, it is necessary to frequently replace the appropriate chamfering device, which increases the labor of employees and makes the chamfering process more cumbersome. Therefore, a double-sided chamfering device is required.

The utility model is further described below in conjunction with the accompanying drawings:

As shown in Figures 1 to 5, a double-sided chamfering device includes a base 1, on which are mounted two symmetrically arranged chamfering mechanisms 2, on which is mounted a clamping mechanism 3, within which is disposed an adjusting mechanism 4, a mounting groove 101 is provided in the middle of the base 1, and two collecting grooves 102 are provided on the top of the base 1, wherein debris generated by chamfering will fall into the collecting grooves 102 for easy collection, and a plurality of electric slide rails 103 are connected to the top of the base 1 by bolts.

In this embodiment, the chamfering mechanism 2 includes two connecting frames 201 that can move left and right. The connecting frames 201 are respectively slidably connected to the electric slide rails 103 on both sides. A motor 202 is connected to the connecting frame 201 by bolts. The output end of the motor 202 is connected to a rotating rod 203 by bolts. An adjusting screw 204 is rotatably connected inside the rotating rod 203. An adjusting block 205 is threadedly connected to the adjusting screw 204. A second motor 206 is connected to the side of the adjusting block 205 by bolts. The output end of the second motor 206 is connected to a chamfering cutter 207 through a coupling. According to the diameter of the cylindrical workpiece that needs to be chamfered, the position of the adjusting block 205 on the adjusting screw 204 is adjusted, so that the chamfering cutter 207 adapts to the diameter of the cylindrical workpiece.

In this embodiment, the clamping mechanism 3 includes two symmetrically arranged first racks 301, a slide rod 302 is slidably connected inside the first rack 301, the slide rod 302 is connected to the mounting groove 101 by bolts, the top of the first rack 301 is connected to a bracket 303 by bolts, and a symmetrically arranged limit block 304 is welded to the top of the bracket 303, and a workpiece 5 to be chamfered is arranged in the limit block 304. By adjusting the distance between the two limit blocks 304, cylindrical workpieces of various diameters can be clamped.

In this embodiment, the adjustment mechanism 4 includes a third motor 401, and the output end of the third motor 401 is connected to two symmetrically arranged bidirectional screws 402, the bidirectional screws 402 are rotatably connected in the mounting groove 101, the bidirectional screws 402 are threadedly connected to the second rack 403, the second rack 403 is meshed with a gear 404, the first rack 301 is meshed with the gear 404, and the symmetry axes of the two first racks 301 and the center point of the output shaft of the first motor 202 are located in the same vertical plane. Such an arrangement enables the chamfering mechanism 2 to have consistent chamfering cutting motions at various locations when chamfering the workpiece 5 to be chamfered, thereby ensuring a good chamfering effect. The first rack 301 and the second rack 403 are slidably connected in the mounting groove 101 The center position of the gear 404 is connected with a connecting shaft 405 by bolts, and the adjusting mechanism 4 includes a gear rod 406, which is threadedly connected to the base 1. The gear rod 406 can clamp the gear 404, and the bidirectional screw 402 drives the second rack 403 to move left and right. The second rack 403 meshes with the gear 404, and the gear 404 drives the first rack 301 to move left and right when it rotates, thereby adjusting the distance of the limit block 304. By clamping the gear 404 by the gear rod 406, the workpiece 5 to be chamfered can be firmly limited in the limit block 304, so as to prevent the bidirectional screw 402 from being subjected to excessive force during chamfering and causing thread slippage, thereby affecting the fixing effect of the limit block 304 on the workpiece 5 to be chamfered.

Working principle: Before using the device, it is necessary to adjust the device according to the diameter and length of the workpiece 5 to be chamfered. First, according to the diameter of the workpiece 5 to be chamfered, the adjusting screw 204 is rotated to move the position of the adjusting block 205 in the rotating rod 203, so that the chamfering knife 207 adapts to the diameter of the workpiece. Then, the workpiece 5 to be chamfered is moved between the two limit blocks 304, and the third motor 401 is turned on. The third motor 401 drives the bidirectional screw 402 to rotate, and the bidirectional screw 402 adjusts the distance of the second rack 403. The second rack 403 meshes with the gear 404. The gear 404 drives the first rack 301 to move left and right when it rotates. The strip 301 drives the bracket 303 to move synchronously, thereby adjusting the distance of the limit block 304, clamping the workpiece 5 to be chamfered in the limit block 304, and finally clamping the gear 404 by the gear rod 406, which can firmly limit the workpiece 5 to be chamfered in the limit block 304, and finally make the electric slide rail 103 push the connecting frame 201 to move to the middle, so that the chamfering knife 207 is close to the chamfering position of the workpiece 5 to be chamfered. After the adjustment is completed, the No. 1 motor 202 is turned on, and the No. 1 motor 202 drives the rotating rod 203 to rotate slowly. At the same time, the second motor 206 is turned on, and the second motor 206 drives the chamfering knife 207 to rotate quickly to chamfer the workpiece 5 to be chamfered.
