Description

Technical Field

[0001] The present application relates to the technical field of workpiece chamfering, and in particular to a chamfering device. Background Art

[0002] As we all know, a tablet press is a pharmaceutical equipment that can press drug powder into tablets of different shapes.

[0003] In the existing system, the chamfer size of the die hole in the tablet press turret is required to be 0.1mm×45°. If the chamfer is too large, drug powder will remain in the chamfer, causing color mixing or reduced yield. If the chamfer is too small or there is no chamfer, it is easy to burr or scratch or even lose the coating (the sharp corner is too small, and the coating is not easy to adhere). Therefore, it is necessary to process the appropriate chamfer size.

[0004] In actual manufacturing, chamfering and deburring by fitters is a common process in the manufacturing industry. Fitters use tools such as chamferers and scrapers to chamfer the edges and openings of machined parts. Some chamfering is done on the machine. The size of the chamfer processed in this way is generally larger than 0.2mm, and some even reach 3-5mm (the size of the chamfer is related to the size of the part. Generally, the larger the part, the larger the chamfer size, except for special requirements). For the chamfering of the opening of the die hole in the tablet press turret, the current processing method is mainly for fitters to rely on experience and use scrapers or manual grinding to chamfer the opening. The quality of parts processed in this way is unstable, the efficiency is low, and it is easy to increase the chamfer, causing the parts to be scrapped.

[0005] Therefore, it is necessary for those skilled in the art to provide a chamfering device that can achieve high-precision chamfering and improve work efficiency in a timely manner. Utility Model Content

[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0054] Please refer to Figures 1 to 9 , Figure 1 This is a schematic diagram of the structure of the chamfering device in the embodiment of the present application; Figure 2 for Figure 1 A front view of the chamfering device shown; Figure 3 for Figure 1 A side view of the chamfering device shown; Figure 4 for Figure 1 A schematic diagram of the structure of the adjusting rod assembly in the chamfering device shown; Figure 5 for Figure 4 A cross-sectional view of the adjustment lever assembly shown; Figure 6 for Figure 1 A schematic diagram of the structure of a chamfering device in the chamfering device shown; Figure 7 for Figure 1 Another schematic diagram of the structure of the chamfering device at another angle shown; Figure 8 This is a schematic diagram of the assembly of the chamfering device and the workpiece to be chamfered in the embodiment of the present application; Fig. 9 It is an assembly cross-sectional view of the chamfering device and the workpiece to be chamfered in the embodiment of the present application.

[0055] The chamfering device provided in the embodiment of the present application includes a chamfering body 1 , a chamfering device 2 and an adjustment mechanism 3 .

[0056] Among them, the chamfering body 1 is used to be positioned and installed on the workpiece 6, the chamferer 2 is movably connected to the chamfering body 1, the chamferer 2 is used to move relative to the chamfering body 1 along a first direction, and the chamferer 2 is used to rotate around the axis of the first direction to chamfer the workpiece 6. Furthermore, the adjustment mechanism 3 includes an adjustment positioning block 31 and an adjustment rod assembly 32, the adjustment positioning block 31 is fixed on the chamfering body 1, the adjustment rod assembly 32 is movably embedded in the adjustment positioning block 31, and the adjustment rod assembly 32 is used to move along the second direction to trigger the chamferer 2 to move along the first direction.

[0057] It should be noted that the so-called second direction may be a direction perpendicular to the first direction. Figure 1 The X-axis direction is shown, and the second direction is as Figure 1 The Y-axis direction is shown.

[0058] It can be seen that when the chamfering device is working, first, the chamfering body 1 is positioned and installed on the workpiece 6 to be chamfered, so that the chamferer 2 is located at the center of the hole to be chamfered, and then, the movement of the adjusting rod assembly 32 along the second direction relative to the adjusting positioning block 31 is triggered to trigger the chamferer 2 to move along the first direction, thereby achieving the purpose of adjusting the relative position of the chamferer 2 and the workpiece 6; after the adjustment is completed, the adjusting rod assembly 32 is separated from the chamferer 2, and the chamferer 2 is rotated around the axis of the first direction to realize the chamfering operation on the workpiece 6.

[0059] In this way, by adjusting the position of the chamfering device 2 relative to the workpiece 6, the chamfering size of the hole to be chamfered on the workpiece 6 can be controlled, thereby achieving the purpose of high-precision chamfering processing.

[0060] Compared with the prior art, the chamfering device provided in the embodiment of the present application has a simple structure, low cost, and easy operation. It can not only greatly improve the work efficiency of chamfering, but also can accurately control the size of the chamfer, with good control accuracy and stable chamfering size, thereby ensuring the quality stability of the chamfering process.

[0061] In some embodiments, the adjustment rod assembly 32 includes an angle positioning pin 321, a locking screw 322, and a connecting piece 323. The angle positioning pin 321 is movably embedded in the adjustment positioning block 31, the angle positioning pin 321 is used to move relative to the adjustment positioning block 31 along the second direction, the locking screw 322 is threadedly screwed to the adjustment positioning block 31, the locking screw 322 is used to rotate relative to the adjustment positioning block 31 to push the angle positioning pin 321 to move, the connecting piece 323 extends out of the locking screw 322 and is connected to the angle positioning pin 321, and the connecting piece 323 is used to move with the angle positioning pin 321 when the locking screw 322 pushes the angle positioning pin 321 to move.

[0062] Specifically, the connecting piece 323 is a connecting screw, and the locking screw 322 connects the angle positioning pin 321 together through the connecting screw. The locking screw 322 is provided with an inner hole for the connecting screw to pass through. The inner hole is a light hole, and the inner diameter of the inner hole is larger than the outer diameter of the connecting screw, so that the connecting screw can freely pass through the locking screw 322. At the same time, after the locking screw 322 connects the angle positioning pin 321 together through the connecting screw, there is a preset gap between the locking screw 322 and the angle positioning pin 321.

[0063] In this way, when the locking screw 322 is rotated through the thread, the gap between the locking screw 322 and the angle positioning pin 321 can be reduced until the locking screw 322 contacts the angle positioning pin 321, and pushes the angle positioning pin 321 and the connecting screw threadedly connected to the angle positioning pin 321 to move forward synchronously. In other words, as the locking screw 322 rotates, the angle positioning pin 321 and the connecting screw do not rotate but only move linearly with the rotation of the thread of the locking screw 322.

[0064] Of course, according to actual needs, the locking screw 322 can be rotated by twisting the hexagonal countersunk hole at the end.

[0065] In order to facilitate triggering the chamfering tool 2 to move along the first direction, a mating groove 221 is provided on the chamfering tool 2, and the mating groove 221 has a mating inclined surface 222; correspondingly, a contact surface 3211 is provided at one end of the angle positioning pin 321 away from the locking screw 322, and the contact surface 3211 contacts and abuts against the mating inclined surface 222 to trigger the chamfering tool 2 to move.

[0066] It can be understood that, driven by the locking screw 322, the angle positioning pin 321 moves linearly along the second direction close to the chamferer 2 until the contact surface 3211 on the angle positioning pin 321 contacts and abuts against the matching inclined surface 222, and the chamferer 2 is subjected to the component force along the first direction, thereby achieving the purpose of triggering the chamferer 2 to move along the first direction.

[0067] Of course, according to actual needs, the matching groove 221 on the chamfering device 2 can be a V-shaped groove, and the end of the angle positioning pin 321 away from the locking screw 322 is a V-shaped structure.

[0068] In some embodiments, the chamfering device 2 includes a grinding head 21 and a straight rod 22. The grinding head 21 is used to chamfer the workpiece 6, and the straight rod 22 is connected to the grinding head 21.

[0069] In order to facilitate the assembly of the chamfering device 2 and the chamfering body 1, the chamfering device further includes a bearing 4, and the straight rod 22 is installed on the chamfering body 1 through the bearing 4. Of course, the bearing 4 can be a deep groove ball bearing 4, the inner ring of the deep groove ball bearing 4 is connected to the straight rod 22 of the chamfering device 2, and the outer ring of the deep groove ball bearing 4 is connected to the chamfering body 1. The chamfering device 2 can move relative to the chamfering body 1 along the first direction, and at the same time, the chamfering device 2 can also rotate relative to the chamfering body 1 around the axis of the first direction.

[0070] In some embodiments, the chamfering device 2 is an integrally formed grinding wheel. The use of a formed grinding wheel can make the surface finish after chamfering high.

[0071] In order to limit the movement of the chamfering device 2 after the position of the chamfering device 2 is adjusted, the chamfering device further includes a locking assembly 5 .

[0072] Specifically, the locking assembly 5 includes a locking sleeve 51 and a locking top screw 52. The locking sleeve 51 is sleeved on the straight rod 22, and the locking top screw 52 connects the locking sleeve 51 and the straight rod 22, so that the locking sleeve 51 is locked to the straight rod 22. That is, after the chamfering tool 2 is adjusted to a good position, the locking sleeve 51 can be connected to the chamfering tool 2 through the locking top screw 52.

[0073] In order to facilitate driving the chamfering device 2 to rotate, the chamfering device further includes a rotary drive member connected to the chamfering device 2 to drive the chamfering device 2 to rotate around an axis in the first direction. The rotary drive member may be a hand electric drill.

[0074] In some embodiments, the chamfering body 1 is provided with at least two positioning bosses 11, and the at least two positioning bosses 11 are used to embed in the workpiece 6 so that the chamfering body 1 is positioned on the workpiece 6 and the chamferer 2 is located at the center of the hole to be chamfered on the workpiece 6.

[0075] Preferably, two positioning bosses 11 can be set at the bottom of the chamfering body 1, and the two positioning bosses 11 are respectively used to embed into the holes on both sides of the hole to be chamfered in the workpiece 6, so that the chamfering body 1 is positioned on the workpiece 6, and the chamferer 2 is located at the center position of the hole to be chamfered on the workpiece 6.

[0076] In some embodiments, the chamfering body 1 is provided with an observation window 12 for observing the position of the chamferer 2 after movement.

[0077] Preferably, the observation window 12 is an arc-shaped notch provided on the chamfered body 1 .

[0078] To sum up, when chamfering, first, place the chamfering device on the workpiece 6, and the two positioning bosses 11 on the chamfering body 1 cooperate with the small clearance of the hole on the workpiece 6 to achieve positioning, ensuring that the chamferer 2 is located at the center of the hole to be chamfered; then, by adjusting the locking screw 322 inside the adjusting mechanism 3, the chamferer 2 is moved downward by utilizing the contact surface 3211 on the angle positioning pin 321 to cooperate with the matching inclined surface 222 on the chamferer 2, and the lowered position of the chamferer 2 can be seen through the arc-shaped observation window 12 on the chamfering body 1. After adjusting the position of the chamferer 2, the locking sleeve 51 and the chamferer 2 are locked by locking the top screw 52, ​​so that the chamfer can remain unchanged in size. After the adjustment is completed, the locking screw 322 is adjusted in the reverse direction to disengage the angle positioning pin 321 from the chamferer 2; finally, the chamferer 2 is rotated by providing power through the electric hand drill. After processing, the chamfering device is taken out, put into the next hole, and the electric hand drill is turned to achieve chamfering.

[0079] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
