Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to, but is not limited to, the technical field of precision shaft machining, and particularly relates to a grinding device. BACKGROUND

[0002] In the production process of a precision shaft, tail pins or knife marks often exist on the end face, so that secondary machining is needed to ensure that the precision shaft meets the production requirements. At present, the tail pins on the end face or the knife marks on the end face are basically solved by secondary turning machining (that is, using a turning tool for grinding) or a horizontal double-end-face grinding machine for grinding the double-end face of the precision shaft. However, the secondary turning machining has low efficiency and low precision for clamping and turning the workpiece of the precision shaft. When the horizontal double-end-face grinding machine grinds, the two grinding wheels grind at the same time, which causes the grinding allowance of the two ends of the precision shaft to be inconsistent, thereby affecting the machining precision and further causing the precision shaft to not meet the production requirements. Therefore, how to improve the precision and efficiency of the secondary machining of the end face of the precision shaft is a technical problem to be solved. CONTENT OF THE UTILITY MODEL

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application. The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed.

[0033] Reference Figures 1 to 5 As shown, the grinding apparatus according to an embodiment of this application includes:

[0034] The feeding assembly 100 includes a feeding wheel 110, a positioning member 120, and a first driving member 130. The feeding wheel 110 has a plurality of feeding slots 111 spaced apart on its surface. The positioning member 120 abuts against the first side of the feeding wheel 110 and protrudes from the feeding wheel 110. The first driving member 130 is used to drive the feeding wheel 110 and the positioning member 120 to rotate synchronously.

[0035] The clamping assembly 200 is located above the feeding wheel 110 and is used to clamp the workpiece 300 that has passed through the feeding channel 111 of the preset processing area.

[0036] The grinding wheel assembly 400 is located on the side of the feed wheel 110 away from the clamping assembly 200. The grinding wheel assembly 400 is used to grind the first end of each workpiece 300 in the processing area facing the grinding wheel assembly 400.

[0037] Therefore, when the grinding wheel assembly 400 grinds the first end of each workpiece 300 in the processing area, the positioning member 120 abuts against the first side of the feeding wheel 110, which can limit the length of the workpiece 300. At the same time, since the clamping assembly 200 clamps the workpiece 300 located on the feeding groove 111 of the feeding wheel 110 in the processing area, it can further ensure that the workpiece 300 will not fall out of the feeding groove 111 during the grinding process, thereby achieving higher precision grinding of the first end of the workpiece 300. As the feeding wheel 110 rotates, the unprocessed workpiece 300 is continuously fed into the processing area, allowing the grinding wheel assembly 400 to continuously grind the workpiece 300. Therefore, compared with related technologies, the embodiments of this application can realize secondary processing of the end face of workpieces 300 such as precision shafts, with higher precision and efficiency.

[0038] Reference Figure 1 and Figure 2 As shown, the grinding wheel assembly 400 includes a grinding wheel 410 and a third driving member 420. The third driving member 420 drives the grinding wheel 410 to rotate, thereby grinding the workpiece 300 in the processing area. This application embodiment does not limit the model of the first driving member 130 and the third driving member 420; those skilled in the art can selectively configure them according to actual needs.

[0039] This application embodiment does not impose any limitations on the dimensions of the feeding wheel 110 and the positioning element 120; those skilled in the art can selectively set them according to actual needs. The positioning element 120 can be set as a disc with a diameter larger than that of the feeding wheel 110, or it can be set as a ring; this application embodiment does not impose any limitations on this. The positioning element 120 and the feeding wheel 110 can be integrally formed or set independently; this application embodiment does not impose any limitations on this.

[0040] Both the feeding wheel 110 and the positioning component 120 are disc-shaped, as shown in the reference. Figure 1 and Figure 2 As shown, the bearing passes through the positioning member 120 and the feeding wheel 110 and is fixedly connected to the fixed end of the first driving member 130 to achieve synchronous rotation control of the positioning member 120 and the feeding wheel 110.

[0041] Reference Figure 5 As shown, the clamping assembly 200 is provided with a clamping arc surface 210, which can be made of a material with a certain degree of elasticity, such as a belt 220.

[0042] Reference Figure 5 As shown, the feeding channel 111 is arranged circumferentially along the surface of the feeding wheel 110. This embodiment does not limit the spacing of the feeding channel 111; those skilled in the art can selectively set it according to the processing requirements of the grinding wheel 410.

[0043] Understandably, referring to Figure 1and Figure 3 As shown, the clamping assembly 200 includes a second driving member, a belt 220 and a plurality of pulleys. The belt 220 is sleeved on each pulley and located in the preset processing area. The belt 220 abuts against the wheel surface of the feeding wheel 110. The second driving member is used to drive each pulley to rotate.

[0044] By setting multiple pulleys, the movement of the belt 220 can be controlled, thereby reducing the friction between the workpiece 300 and the belt 220 when the workpiece 300 rotates with the feed wheel 110 and during processing, thus extending the life of the belt 220. This application embodiment does not limit the number of second driving components. Those skilled in the art can choose to set multiple or one according to actual needs. For example, if a belt 220 or chain is used for linkage drive, then one driving component can be set. In other embodiments, one can be set for each pulley.

[0045] The embodiments of this application do not limit the number of pulleys.

[0046] Understandably, referring to Figure 3 As shown, the multiple pulleys include a first pulley 231, two second pulleys 232 and two third pulleys 233; the second pulleys 232 and the third pulleys 233 are respectively located on both sides of the first pulley 231, and the two second pulleys 232 and the two third pulleys 233 are arranged correspondingly.

[0047] By correspondingly setting two second pulleys 232 and two third pulleys 233, it can be further ensured that the pressing arc surface 210 formed by the belt 220 matches the wheel surface of the feed wheel 110 in the processing area, resulting in a better pressing effect. The first pulley 231 can keep the belt 220 in a taut state, further improving the pressing effect.

[0048] Understandably, belt 220 has a certain degree of elasticity.

[0049] Understandably, referring to Figures 1 to 3 As shown, the grinding device also includes a first mounting plate 510, and the fixed ends of each pulley, feed wheel 110 and positioning member 120 are connected to the first mounting plate 510. The first mounting plate 510 is also provided with an adjustment groove 511, and the fixed end of the first pulley 231 is slidably disposed in the adjustment groove 511.

[0050] By setting up the first mounting plate 510 and installing each pulley, feeding wheel 110 and positioning component 120 on the first mounting plate 510, the ease of installation can be improved, and the expected effect of each pulley, feeding wheel 110 and positioning component 120 after installation can be further ensured.

[0051] Understandably, referring to Figure 1 andFigure 2 As shown, the grinding device also includes an adjuster 520, which is used to adjust the position of the fixed end of the first pulley 231 in the adjusting groove 511.

[0052] The present application does not limit the structure of the regulator 520. In some embodiments, the regulator 520 can be set as a stud 521, one end of which is connected to the first pulley 231. The position of the stud 521 protruding from the first mounting plate 510 is adjusted by the nut 522 to realize the position of the first pulley 231 in the adjustment groove 511, thereby adjusting the tension of the belt 220.

[0053] Understandably, all pulleys are equipped with belt 220 mounting slots.

[0054] By providing belt 220 mounting grooves for each pulley, the probability of belt 220 detaching from the pulley can be reduced.

[0055] Understandably, referring to Figure 2 and Figure 3 As shown, the grinding device also includes a base 530 and a receiving assembly. The base 530 has a receiving groove 531. The first mounting plate 510 and the grinding wheel assembly 400 are both located on the base 530 and are located on opposite sides of the receiving groove 531. The feeding wheel 110 and the positioning member 120 partially pass through the receiving groove 531. The receiving assembly is located below the receiving groove 531.

[0056] By setting the base 530, the material receiving component and other parts can be separated. The material receiving component can automatically receive the workpiece 300 that falls due to gravity, thereby saving energy and achieving automatic material receiving.

[0057] The receiving assembly may include a receiving tray or container, or a conveyor track. This application does not limit the specific components, and those skilled in the art can selectively configure them according to actual needs.

[0058] Understandably, referring to Figure 1 and Figure 2 As shown, the grinding device also includes a vibratory feeder assembly 600, which is located on one side of the feed roller 110 and is used to automatically feed material to the feed roller 110.

[0059] By setting the vibratory feeder assembly 600, the workpiece 300 can be automatically fed and the processing end face of the fed workpiece 300 can be made to face the grinding wheel assembly 400.

[0060] Understandably, referring to Figures 1 to 4As shown, the vibratory feeder assembly 600 includes a vibratory feeder 610 and a conveying track 620. The conveying track 620 is inclined toward the feeding wheel 110, and the first end of the conveying track 620 away from the feeding wheel 110 is higher than the second end close to the feeding wheel 110.

[0061] By raising the first end of the conveying track 620 higher than the second end, the workpiece 300 can be automatically fed under the action of gravity. When the feeding channel is filled with workpiece 300, the feeding wheel 110 is driven to rotate, so that the empty feeding slot 111 is aligned with the conveying port of the conveying track 620, thereby realizing automatic feeding without the need for additional power and with lower energy consumption.

[0062] Understandably, the vibratory feeder 610 is equipped with a vision component and an air blowing component. The vision component is used to control the air blowing component to blow off the workpiece 300 after it is detected that the machined surface does not match the preset direction so as to re-divide the direction.

[0063] By adding a vision component to perform visual analysis on the workpiece 300 after it is oriented, it is possible to identify workpieces 300 whose machining surface does not conform to the preset direction. The workpiece 300 can be blown off by the blowing component, thereby further ensuring that the machining surface of the workpiece 300 conveyed to the conveying track 620 is facing the grinding wheel assembly 400.

[0064] The vision component can be a camera, infrared sensor, or other device capable of recognizing contours. The air blowing component can be an air hole or a nozzle; however, this application does not limit the specific configuration, and those skilled in the art can choose to configure it according to actual needs.

[0065] Reference Figure 2 As shown, the vibratory feeder 610 is provided with a directional track 611 and a hopper area 612. During vibration, the workpieces 300 in the hopper area 612 will enter the directional track 611 in an orderly manner. The air blowing component is arranged on the side of the directional track 611. The embodiments of this application do not limit the structure of the air blowing component, nor the number of air blowing components. Those skilled in the art can selectively set it according to actual needs.

[0066] The above is a detailed description of the preferred embodiments of this application. However, this application is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
