Description

Technical Field

[0001] This application relates to the field of machining equipment technology, and in particular to a fixed-length chamfering device. Background Technology

[0002] Miniature shafts, as precision components, are widely used in precision instruments such as electric motors and circuit boards. During the machining of miniature shafts, their ends are typically chamfered. Traditional chamfering processes usually involve semi-manual grinding, which is time-consuming. With technological advancements, chamfering machines are now commonly used for miniature shaft chamfering. Automated grinding not only alters the local shape of the miniature shaft but also removes burrs from its surface, resulting in a smoother finish. However, most existing chamfering machines use robotic arms to clamp the miniature shaft before performing the chamfering process. The robotic arms, due to their reciprocating motion, are not highly efficient.

[0003] Before the chamfering process, miniature shafts typically undergo a length-fixing process to grind their end faces to improve precision. In existing technology, the length-fixing and chamfering processes are usually completed using two separate machines. After the miniature shaft is lengthened, it needs to be shaped and transferred to the chamfering device, resulting in significant time wastage between the length-fixing and chamfering processes. Therefore, to further improve the processing efficiency of miniature shafts, a device capable of simultaneously performing length-fixing and chamfering is urgently needed. Utility Model Content

[0004] One objective of this application is to provide a fixed-length chamfering device that can solve at least one of the defects in the aforementioned background art.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a fixed-length chamfering device, comprising a body, a fixed-length mechanism, and a chamfering mechanism. A rotating assembly for conveying a micro shaft is rotatably mounted on the body. A support assembly is provided on the body, and a fixing assembly is mounted on the support assembly. The fixing assembly rotates synchronously with the rotating assembly and is used to cooperate with the rotating assembly in conveying the micro shaft. The fixed-length mechanism is used to grind the end face of the micro shaft. The chamfering mechanism includes a chamfering grinding disc and a housing. A groove is provided on the housing. The chamfering grinding disc is rotatably mounted inside the housing and partially protrudes from the groove. The chamfering mechanism is connected to a first adjusting assembly, which is used to drive the chamfering mechanism to move.

[0006] With the above setup, the micro shaft to be processed can be placed into the rotating assembly to perform the fixed-length process and the chamfering process sequentially. The fixing structure can fix the micro shaft to the rotating assembly, thereby preventing the micro shaft from falling off the rotating assembly due to its own weight during transportation. When the required chamfer specifications and size change, the position of the chamfering mechanism can be adjusted through the first adjusting component, thereby grinding chamfers of different specifications on the micro shaft.

[0007] Preferably, the rotating component is a conveyor wheel, which is rotatably mounted on the machine body and has multiple material troughs. This configuration allows the micro-shafts to be placed in the material troughs, and as the conveyor wheel rotates, the micro-shafts are processed sequentially according to their position, further improving the processing efficiency of the micro-shafts and enabling the processing of more micro-shafts per unit time.

[0008] Preferably, the fixing component is a conveyor belt, located between the support component and the conveyor wheel. The support component includes a first support member and a second support member. The conveyor belt located between the first and second support members cooperates with the conveyor wheel and blocks the material trough. This configuration limits the movement range of the conveyor wheel using the first and second support members. When the microshaft is placed in the material trough, the conveyor belt within the first and second support members adheres to the microshaft and presses it tightly against the bottom wall of the material trough, thus preventing the microshaft from detaching. After the microshaft is processed, it continues to rotate with the conveyor wheel. When the conveyor belt in the area where the microshaft is located detaches from the conveyor wheel, the limiting effect on the microshaft is released.

[0009] Preferably, the support assembly further includes a third support member, a fourth support member, and a fifth support member, which cooperate to tighten the conveyor belt and make it fit tightly against the conveyor wheel. This arrangement allows the third, fourth, and fifth support members to tighten the conveyor belt away from the conveyor wheel, enabling a portion of the conveyor belt to be taut and fit tightly against the material trough, ensuring that the material can be stably placed and conveyed within the material trough.

[0010] Preferably, the machine body is equipped with a first motor and a second motor. The rotating shaft of the first motor is fixedly connected to the conveyor wheel. The rotating shaft of the second motor is provided with a gear that cooperates with the conveyor belt. With this configuration, the first motor drives the conveyor wheel to rotate at a uniform speed, making the processing of the micro shaft more standardized. The second motor drives the conveyor belt to rotate actively, and the conveyor wheel and the conveyor belt have the same rotational speed, so as to avoid wear between the conveyor wheel and the conveyor belt due to speed difference.

[0011] Preferably, the first adjustment component includes a horizontal adjuster and a vertical adjuster. The horizontal adjuster is used to drive the chamfering mechanism to move left and right, and the vertical adjuster is used to drive the chamfering mechanism to move up and down. This configuration allows the position of the chamfering mechanism to be adjusted via the horizontal and vertical adjusters, ensuring that the chamfering mechanism can adjust its position according to actual needs, making the chamfering grinding disc fit the micro-shaft more closely.

[0012] Preferably, the length-fixing mechanism is installed on the machine body. The length-fixing mechanism includes a length-fixing grinding disc and a fixed disc, which are respectively arranged on both sides of the conveyor wheel. A second adjustment component for adjusting the position of the length-fixing grinding disc is connected to the length-fixing grinding disc, and a third adjustment component for adjusting the position of the fixed disc is connected to the fixed disc. With this configuration, the fixed disc can limit the position of the micro-shaft, while the length-fixing grinding disc can grind the end face of the micro-shaft and change its length to better meet processing standards. After length-fixing, the micro-shaft can immediately undergo a chamfering process, further improving the processing efficiency of the micro-shaft. The second and third adjustment components work together to adjust the positions of the fixed disc and the length-fixing grinding disc, thereby grinding the micro-shaft to the desired length.

[0013] Preferably, a first drive assembly is mounted on the fixed-length mechanism, and a second drive assembly is mounted on the chamfering mechanism. The first drive assembly drives the fixed-length grinding disc to rotate, and the second drive assembly drives the chamfering grinding disc to rotate. This configuration allows the first and second drive assemblies to provide power to the fixed-length grinding disc and the chamfering grinding disc respectively, enabling them to rotate at high speed and thus grind the surface of the micro-shaft.

[0014] Preferably, a feeding section for filling microshafts is installed above the conveyor wheel; the feeding section is funnel-shaped, wider at the top and narrower at the bottom, and the size of the lower opening of the feeding section matches the thickness of the conveyor wheel. With this configuration, microshafts can be filled into the material trough through the feeding section. When a microshaft enters the feeding section, it slides along the inclined surface of the feeding section into the material trough under the action of gravity. Excess microshafts accumulate in the feeding section, and as the conveyor wheel rotates, the number of microshafts in the feeding section gradually decreases.

[0015] Preferably, the machine body is equipped with a discharge section, and the discharge section is provided with a receiving plate, which is located between the conveyor wheel and the conveyor belt. After being cut to a fixed length and chamfered, the miniature shaft can move along the conveyor wheel towards the discharge section, and then the miniature shaft enters the discharge section for collection through the receiving plate.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: Once the micro-shaft is placed inside the rotating assembly, it is transported to the chamfering mechanism by the fixing assembly for the chamfering process. When the micro-shaft is placed in the material trough, it can be chamfered immediately after reaching a fixed length as the conveyor wheel rotates, further improving the processing efficiency of the micro-shaft. It can achieve single-end face grinding and chamfering grinding of the micro-shaft in one step, suitable for PCB drill bits and milling cutters. The conveyor belt can be pulled tightly against the material trough by the support assembly, further improving the limiting effect on the micro-shaft within the material trough.

[0017] When the machining standards of the miniature shaft change, the position of the chamfering mechanism can be adjusted via the first adjusting component, and the position of the length-fixing mechanism can be adjusted via the second and third adjusting components. This invention can perform length fixing and chamfering simultaneously, and has the advantages of small footprint and high production efficiency. Attached Figure Description

[0025] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0029] One aspect of this application provides a fixed-length chamfering device, one preferred embodiment of which is, for example... Figure 1 and Figure 2As shown, the device includes a body 1, a length-fixing mechanism 6, and a chamfering mechanism 2. A rotating assembly for conveying a micro-shaft is rotatably mounted on the body 1. A support assembly 5 is provided on the body 1, and a fixing assembly is mounted on the support assembly 5. The fixing assembly can rotate synchronously with the rotating assembly. The fixing assembly cooperates with the rotating assembly to convey the micro-shaft, preventing the micro-shaft from detaching from the rotating assembly due to its own weight during transport, further improving the safety of micro-shaft conveying. The length-fixing mechanism 6 can be used to grind the end face of the micro-shaft, thereby changing the length of the micro-shaft. The chamfering mechanism 2 includes a chamfering grinding disc 21 and a housing 22. The housing 22 has a groove 220. The chamfering grinding disc 21 is rotatably mounted inside the housing 22 and partially protrudes from the groove 220. When the rotating assembly transports the micro-shaft to the vicinity of the groove 220, the chamfering grinding disc 21 fits against the micro-shaft and forms a chamfer on the surface of the micro-shaft through grinding. In addition, to further improve the applicability of this device, a first adjustment component 100 is connected to the chamfering mechanism 2. When the required chamfer specifications and size change, the position of the chamfering mechanism 2 can be adjusted by the first adjustment component 100, thereby grinding chamfers of different specifications on the micro shaft.

[0030] It is understood that this application has both fixed length and chamfering functions, and can realize one-time forming of single end face grinding and chamfering grinding of micro shafts, which is suitable for PCB drill bits and milling cutters.

[0031] Specifically, such as Figure 3 As shown, the rotating component is a conveyor wheel 3, which is rotatably mounted on the machine body 1. The conveyor wheel 3 is provided with multiple material troughs 31. With this arrangement, the micro shaft can be placed in the material troughs 31. As the conveyor wheel 3 rotates, the micro shaft will undergo fixed-length processing and chamfering processing in sequence according to its position, which can further improve the processing efficiency of the micro shaft and process more micro shafts per unit time.

[0032] Furthermore, such as Figure 3 As shown, the fixing component is a conveyor belt 4, which is located between the support component 5 and the conveyor wheel 3. The support component 5 includes a first support member 51 and a second support member 52. The conveyor belt 4, located between the first support member 51 and the second support member 52, cooperates with the conveyor wheel 3 and blocks the material trough 31. The first support member 51 and the second support member 52 can limit the cooperation range between the conveyor wheel 3 and the conveyor belt 4. When the micro shaft is placed in the material trough 31, the conveyor belt 4 located in the first support member 51 and the second support member 52 is in contact with the micro shaft and squeezes the micro shaft tightly against the bottom wall of the material trough 31, thereby cooperating with the conveyor wheel to transport the micro shaft. After the micro shaft is processed, the micro shaft continues to rotate with the conveyor wheel 3. The limiting effect on the micro shaft can only be released when the conveyor belt 4 in the area where the micro shaft is located is disengaged from the conveyor wheel 3.

[0033] In this embodiment, as Figure 3 and Figure 4 As shown, the support assembly 5 also includes a third support member 53, a fourth support member 54, and a fifth support member 55. These three components work together to tighten the conveyor belt 4 and ensure it is tightly pressed against the conveyor wheel 3, guaranteeing that no gaps appear in the contact area between the conveyor wheel 3 and the conveyor belt 4. The conveyor belt 4 is used to limit the movement of the micro-shaft. Compared to the clamping assembly used in transmission, the conveyor belt 4 in this application is made of a softer material and has a certain amount of deformation space, thus preventing scratches from being left on the surface of the micro-shaft.

[0034] To further improve the machining efficiency of miniature shafts, in some embodiments of this application, such as... Figure 4 As shown, a first motor 200 and a second motor 201 are installed on the machine body 1. The first motor 200 drives the conveyor wheel 3 to rotate. The rotating shaft of the first motor 200 is fixedly connected to the conveyor wheel 3. When the motor is running, the rotating shaft drives the conveyor wheel 3 to rotate at a constant speed. Furthermore, a gear 202 that can cooperate with the conveyor belt 4 is provided on the rotating shaft of the second motor 201. The second motor 201 drives the gear 202 to rotate synchronously through the rotating shaft. When the gear 202 rotates, it drives the conveyor belt 4 to rotate synchronously. In addition, the rotational speeds of the first motor 200 and the second motor 201 should be matched to ensure that the conveyor belt 4 and the conveyor wheel 3 rotate synchronously, thereby avoiding wear caused by the speed difference between the conveyor wheel 3 and the conveyor belt 4.

[0035] In this embodiment, as Figure 2 As shown, the first adjustment component 100 includes a horizontal adjuster 101 and a vertical adjuster 102. The horizontal adjuster 101 is used to drive the chamfering mechanism 2 to move left and right, and the vertical adjuster 102 is used to drive the chamfering mechanism 2 to move up and down. By adjusting the position of the chamfering mechanism 2 through the horizontal adjuster 101 and the vertical adjuster 102, it is ensured that the chamfering mechanism 2 can adjust its own position according to actual needs, so that the chamfering grinding disc 21 fits the micro shaft more closely.

[0036] In this embodiment, as Figure 1 and Figure 5As shown, the length-fixing mechanism 6 is installed on the machine body 1. The length-fixing mechanism 6 includes a length-fixing grinding disc 61 and a fixed disc 62, which are respectively arranged on both sides of the conveyor wheel 3. When the machine is running, both the length-fixing grinding disc 61 and the fixed disc 62 have overlapping surfaces with the conveyor wheel 3, so that the micro shaft can change its size under the grinding of the length-fixing grinding disc 61 to better meet the processing standards. The fixed disc 62 is used to limit the position of the micro shaft and ensure that the end face of the micro shaft can fit against the length-fixing grinding disc 61. After the micro shaft is lengthened, a chamfering process can be performed immediately, further improving the processing efficiency of the micro shaft. In addition, a second adjustment component 400 for adjusting the position of the fixed length grinding disc 61 is connected to the fixed length grinding disc 61, and a third adjustment component 401 for adjusting the position of the fixed disc 62 is connected to the fixed disc 62. The operator can adjust the distance between the fixed disc 62 and the fixed length grinding disc 61 by manipulating the second adjustment component 400 and / or the third adjustment component 401, thereby grinding the micro shaft to the desired fixed length.

[0037] Furthermore, such as Figure 2 and Figure 5 As shown, a first drive assembly 300 is mounted on the fixed-length mechanism 6, and a second drive assembly 301 is mounted on the chamfering mechanism 2. The first drive assembly 300 drives the fixed-length grinding disc 61 to rotate, and the second drive assembly 301 drives the chamfering grinding disc 21 to rotate. By providing power to the fixed-length grinding disc 61 and the chamfering grinding disc 21 respectively through the first drive assembly 300 and the second drive assembly 301, both can rotate at high speed, thereby grinding the surface of the micro shaft and further improving the processing efficiency of the micro shaft.

[0038] In this embodiment, as Figure 1 and Figure 6 As shown, a feeding section 500 for filling micro shafts is installed above the conveyor wheel 3. The feeding section 500 is funnel-shaped, wider at the top and narrower at the bottom, and the size of the lower opening of the feeding section 500 matches the thickness of the conveyor wheel 3. The operator can place the micro shafts in the feeding section 500. Under the action of gravity, the micro shafts will slide along the inclined surface of the feeding section 500 into the material trough 31. Then, the micro shafts will rotate with the conveyor wheel 3 and undergo fixed-length and chamfering processing. Excess micro shafts will accumulate in the feeding section 500. As the conveyor wheel 3 rotates, the number of micro shafts in the feeding section 500 will gradually decrease.

[0039] Furthermore, such as Figure 1 and Figure 6As shown, a discharge section 600 is also installed on the machine body 1. A receiving plate 601 is provided on the discharge section 600, and part of the receiving plate 601 is located between the conveyor wheel 3 and the conveyor belt 4. After being fixed in length and chamfered, the micro shaft can approach the discharge section 600 along the conveyor wheel 3, and then the micro shaft enters the discharge section 600 for collection through the receiving plate 601. Furthermore, in order to avoid the micro shafts accumulating near the receiving plate 601, the discharge section 600 can be designed in an inclined state.

[0040] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
