Description

Technical Field

[0001] The present application relates to the field of mechanical manufacturing technology, and in particular to a grinding seat and a grinding device. Background Art

[0002] In the process of mechanical manufacturing, it is often necessary to grind various workpieces. When grinding, the workpiece is generally placed on a grinding seat for fixing, and then the workpiece is grinded by a grinding machine. Among these workpieces, some workpieces have a spherical surface, which results in poor fixing effect on the grinding seat, so that the grinding effect is relatively poor when the grinding machine grinds around the spherical part of the workpiece.

[0003] Current grinding seats can fix workpieces with spherical surfaces. However, when the grinding machine grinds it, the concentricity of its spherical surface cannot be well controlled. Utility Model Content

[0004] In view of this, the present application provides a grinding seat and a grinding device capable of improving the concentricity of the spherical surface of a workpiece.

[0005] Some embodiments of the first aspect of the present application provide a grinding seat for carrying a workpiece to be ground, wherein the workpiece includes an inner surface and an outer surface. The grinding seat includes a support mechanism for carrying the workpiece, wherein the support mechanism has a spherical surface, and the grinding seat also includes an adsorption member and a driving member, wherein the adsorption member is arranged on the support mechanism, and the adsorption member is used to adsorb and fix the workpiece of the support mechanism. The driving member is connected to the support mechanism, and the driving member is used to drive the support mechanism to rotate around a predetermined axis, and the predetermined axis passes through the center of the spherical surface of the support mechanism.

[0006] In the above-mentioned grinding seat, the supporting mechanism has a spherical surface. When the workpiece to be ground has a spherical surface, it is beneficial for the supporting mechanism to carry the workpiece. In addition, the driving member can drive the supporting mechanism to rotate around a predetermined axis, and the predetermined axis passes through the center of the spherical surface of the supporting mechanism. When the workpiece is ground, it is beneficial for the supporting mechanism to drive the workpiece to rotate, which is beneficial for the workpiece to be ground evenly, thereby facilitating the concentricity of the spherical surface of the workpiece.

[0007] In some embodiments, the adsorption element includes an adsorption area, and the predetermined axis also passes through the center of the adsorption area.

[0008] In the above-mentioned grinding seat, when the driving member is working, the workpiece fixed to the supporting mechanism rotates around a predetermined axis driven by the driving member, and the predetermined axis passes through the center of the adsorption area, which is beneficial to reducing the influence of the centrifugal force exerted on the workpiece on the adsorption force of the adsorption member on the workpiece, thereby helping to improve the stability of the workpiece fixed to the grinding seat.

[0009] In some embodiments, the support mechanism includes a first support member and a second support member, the first support member is used to abut against the inner surface of the workpiece, the second support member is used to abut against the outer surface of the workpiece, and the second support member is detachably fixed to the first support member.

[0010] In the above-mentioned grinding seat, the first support member abuts against the inner surface of the workpiece, and the second support member abuts against the outer surface of the workpiece, which is equivalent to the workpiece being clamped by the first support member and the second support member, thereby helping to reduce the edge collapse of the workpiece during the grinding process.

[0011] In some embodiments, a connection block is disposed on the second support member, and a magnetic block is disposed on the first support member, and the magnetic block and the connection block are connected by magnetic attraction.

[0012] In the above-mentioned grinding seat, compared with the connection methods of the snap-fit ​​or buckle structure, on the one hand, the magnetic attraction connection method is conducive to simplifying the structural design; on the other hand, the effect of magnetic attraction is conducive to guiding the connection between the first support member and the second support member, thereby helping to improve the convenience and accuracy of the connection.

[0013] In some embodiments, the magnetic block is disposed inside the first support member.

[0014] The above-mentioned grinding seat is conducive to better fitting the first support member to the inner surface of the workpiece, improving the stability of the support, and is also conducive to reducing the debris generated by the magnetic block adsorption grinding.

[0015] In some embodiments, the connection block protrudes from the surface of the second support member, the first support member has a mounting groove for arranging the magnetic block, and when the support mechanism carries the workpiece, the connection block passes through the inner and outer surfaces of the workpiece and contacts the magnetic block.

[0016] In the above-mentioned grinding seat, the connection block is in contact with the magnetic block, which is beneficial to enhancing the magnetic force between the connection block and the magnetic block, improving the connection strength between the first support member and the second support member, and thus facilitating improving the supporting effect on the workpiece.

[0017] In some embodiments, the driving member includes a motor and a transmission belt, and the motor is connected to the support mechanism via the transmission belt to drive the support mechanism to perform rotational motion.

[0018] In the above-mentioned grinding seat, the motor can output a uniform rotation speed, and driving the supporting mechanism by transmission is beneficial to improving the stability of the rotational motion.

[0019] Some embodiments of the second aspect of the present application provide a grinding device for grinding a workpiece to be ground, the workpiece comprising an inner surface and an outer surface, the grinding device comprising: a grinding seat as in the first aspect of the present application; a grinding assembly, which grinds at least the outer surface of the workpiece; and a movable assembly, which is connected to the grinding assembly to adjust the position of the grinding assembly.

[0020] In the above-mentioned grinding device, the grinding seat involved in the first aspect of the present application is adopted, and the position of the grinding component for grinding the workpiece is adjusted by a movable component without changing the position of the workpiece, which is conducive to maintaining stable rotational motion of the workpiece on the grinding seat, thereby helping to further improve the concentricity of the spherical surface of the workpiece.

[0021] In some embodiments, the movable assembly includes a base and a movable arm movably connected to the base, the grinding assembly includes a mounting seat and a grinding head disposed on the mounting seat, and the mounting seat and the movable arm are movably connected via an elastic component.

[0022] In the above-mentioned grinding device, in the process of adjusting the position of the grinding component through the movable component, if the force applied by the grinding component to the workpiece is large, the elastic component can store part of the force as elastic potential energy, and then gradually release the elastic potential energy, which is helpful to reduce the situation where part of the workpiece is over-grinded, thereby helping to improve the quality of the workpiece after grinding.

[0023] In some embodiments, the mounting seat and the movable arm are also movably connected via a rigid component, and the mounting seat can move along the rigid component relative to the movable arm.

[0024] In the above-mentioned grinding device, the rigid component is used to help guide the deformation direction of the elastic component, thereby helping to reduce the unexpected swing of the grinding head caused by the deformation of the elastic component.

[0025] In the present application, the workpiece is first placed on the first support member of the supporting mechanism, and then the second support member of the supporting mechanism is fixed to the first support member, thereby forming support for the inner and outer surfaces of the workpiece, thereby reducing the edge collapse of the workpiece during the grinding process. The adsorption member adsorbs and fixes the workpiece, thereby improving the stability of the workpiece fixed to the supporting mechanism. Then the driving member drives the supporting mechanism to rotate around a predetermined axis, thereby driving the workpiece fixed to the supporting mechanism to rotate. At the same time, the grinding head also starts to rotate, and the movable arm adjusts the position of the grinding head to grind the workpiece. In this way, the workpiece is helped to be evenly ground, thereby helping to improve the concentricity of the spherical surface of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0077] The first aspect of the present application discloses a grinding seat for carrying a workpiece to be ground, wherein the workpiece includes an inner surface and an outer surface, and the grinding seat includes a supporting mechanism for carrying the workpiece, wherein the supporting mechanism has a spherical surface, and the grinding seat also includes: an adsorption member, which is arranged on the supporting mechanism, and the adsorption member is used to adsorb and fix the workpiece on the supporting mechanism; and a driving member, which is connected to the supporting mechanism, and the driving member is used to drive the supporting mechanism to rotate around a predetermined axis, and the predetermined axis passes through the center of the spherical surface of the supporting mechanism.

[0078] In the above-mentioned grinding seat, the supporting mechanism has a spherical surface. When the workpiece to be ground has a spherical surface, it is beneficial for the supporting mechanism to carry the workpiece. In addition, the driving member can drive the supporting mechanism to rotate around a predetermined axis, and the predetermined axis passes through the center of the spherical surface of the supporting mechanism. When the workpiece is ground, it is beneficial for the supporting mechanism to drive the workpiece to rotate, which is beneficial for the workpiece to be ground evenly, thereby facilitating the concentricity of the spherical surface of the workpiece.

[0080] In the above-mentioned grinding device, the grinding seat involved in the first aspect of the present application is adopted, and the position of the grinding component for grinding the workpiece is adjusted by a movable component without changing the position of the workpiece, which is conducive to maintaining stable rotational motion of the workpiece on the grinding seat, thereby helping to further improve the concentricity of the spherical surface of the workpiece.

[0081] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0082] See also Figure 1 The embodiment of the present application provides a grinding seat 10 for carrying a workpiece 2 to be ground, wherein the workpiece 2 includes an inner surface and an outer surface.

[0083] In some embodiments, the inner surface comprises a spherical surface.

[0084] In some embodiments, the outer surface comprises a spherical surface.

[0085] In some embodiments, the workpiece 2 does not have a spherical surface.

[0086] See also Figure 1 The grinding seat 10 includes a supporting mechanism 110, an adsorbing member 120 and a driving member 130. The adsorbing member 120 is disposed on the supporting mechanism 110, and the driving member 130 is connected to the supporting mechanism 110. The supporting mechanism 110 is used to carry the workpiece 2, the adsorbing member 120 is used to adsorb and fix the workpiece 2 carried on the supporting mechanism 110, and the driving member 130 is used to drive the supporting mechanism 110 to rotate around a predetermined axis L.

[0087] See also Figure 1 In some embodiments, the support mechanism 110 has a spherical surface, which is conducive to better supporting the workpiece 2 having a spherical surface.

[0088] See also Figure 1 In some embodiments, the support mechanism 110 includes a first support member 1110 and a second support member 1120, wherein the first support member 1110 is used to abut against the inner surface of the workpiece 2, and the second support member 1120 is used to abut against the outer surface of the workpiece 2, and the second support member 1120 can be detachably fixed to the first support member 1110. In this way, the first support member 1110 abuts against the inner surface of the workpiece 2, and the second support member 1120 abuts against the outer surface of the workpiece 2, which is equivalent to the workpiece 2 being clamped by the first support member 1110 and the second support member 1120, thereby helping to reduce the edge collapse of the workpiece 2 during the grinding process. In the present application, when the workpiece 2 is carried by the support mechanism 110, the workpiece 2 can be first carried on the first support member 1110, and then the second support member 1120 can be fixed to the first support member 1110.

[0089] In some embodiments, the second support member 1120 is made of ceramic material, which can help improve the hardness of the second support member 1120 and help the second support member 1120 to resist grinding.

[0090] In some embodiments, the spherical surface of the support mechanism 110 exists on the first support member 1110. In some embodiments, the spherical surface of the support mechanism 110 exists on the second support member 1120.

[0091] In some embodiments, the spherical surface of the supporting mechanism 110 exists on both the first supporting member 1110 and the second supporting member 1120 .

[0092] See also Figure 2, a connection block 140 is provided on the second support member 1120, and a magnetic block 150 is provided on the first support member 1110, and the magnetic block 150 is connected to the connection block 140 by magnetic attraction. Thus, compared with the connection methods of snap-fit ​​or buckle structures, on the one hand, the magnetic attraction connection method is conducive to simplifying the structural design; on the other hand, the effect of magnetic attraction is conducive to guiding the connection between the first support member 1110 and the second support member 1120, thereby facilitating the convenience and accuracy of the connection.

[0093] In some embodiments, the connection block 140 includes a metal material, so that the magnetic block 150 can magnetically attract the connection block 140 .

[0094] In some embodiments, the connection block 140 is disposed on the first support member 1110, and the magnetic block 150 is disposed on the second support member 1120. In this way, the second support member 1120 can be detachably fixed to the first support member 1110, which is conducive to improving the convenience of replacing the magnetic block 150.

[0095] See also Figure 2 , the magnetic block 150 is disposed inside the first support member 1110. In other words, the magnetic block 150 does not protrude from the surface of the first support member 1110. This is conducive to better fitting the first support member 1110 with the inner surface of the workpiece 2, improving the stability of the support, and also helping to reduce the debris generated by the magnetic block 150 adsorbing the grinding.

[0096] See also Figure 2 , the connection block 140 protrudes from the surface of the second support member 1120, and the first support member 1110 has a mounting groove for arranging the magnetic block 150. When the support mechanism 110 carries the workpiece 2, the connection block 140 passes through the inner surface and the outer surface of the workpiece 2 and contacts the magnetic block 150. In this way, the connection block 140 contacts the magnetic block 150, which is conducive to enhancing the magnetic force between the connection block 140 and the magnetic block 150, improving the connection strength between the first support member 1110 and the second support member 1120, and thus helping to improve the support effect on the workpiece 2.

[0097] See also Figure 2 As mentioned above, the grinding seat 10 further includes an adsorption member 120, which is used to adsorb and fix the workpiece 2 on the support mechanism 110. In other words, the adsorption member 120 can adsorb and fix the workpiece 2 carried by the support mechanism 110. In this way, it is helpful to reduce the shaking of the workpiece 2 during the grinding process and improve the stability of the grinding seat 10 in carrying the workpiece 2.

[0098] In some embodiments, see Figure 2, the adsorption member 120 is disposed on the first support member 1110 of the support mechanism 110. Thus, compared with the adsorption member 120 being disposed on the second support member 1120 that can be detached from the first support member 1110, the position of the adsorption member 120 can be more stable.

[0099] See also Figure 2 , the adsorption member 120 includes an adsorption area 1210, and the predetermined axis L also passes through the center of the adsorption area 1210. In this way, when the driving member 130 is working, the workpiece 2 fixed to the support mechanism 110 rotates around the predetermined axis L driven by the driving member 130, and the predetermined axis L passes through the center of the adsorption area 1210, which is conducive to reducing the influence of the centrifugal force on the workpiece 2 on the adsorption force of the adsorption member 120 on the workpiece 2, thereby facilitating the stability of the workpiece 2 fixed to the grinding seat 10.

[0100] In some embodiments, the adsorbent 120 fixes the workpiece 2 by vacuum adsorption. In some embodiments, the adsorbent 120 includes a suction cup, which adsorbs the workpiece 2 to fix the workpiece 2. In some embodiments, the adsorption force of the adsorbent 120 on the workpiece 2 comes from atmospheric pressure. Figure 2 The adsorption member 120 includes an air hole 1220, and the air hole 1220 is connected to an external pneumatic system. In this way, it is helpful to better control the adsorption force of the adsorption member 120 on the workpiece 2, so as to adsorb or release the workpiece 2.

[0101] In some embodiments, the adsorption member 120 fixes the workpiece 2 by magnetic adsorption, and the adsorption member 120 includes a magnet.

[0102] See also Figure 1 As mentioned above, the grinding seat 10 further includes a driving member 130, and the driving member 130 is used to drive the supporting mechanism 110 to rotate around a predetermined axis L. The predetermined axis L passes through the center of the spherical surface of the supporting mechanism 110. It can be understood that when the workpiece 2 having a spherical surface is carried on the supporting mechanism 110, the predetermined axis L passes through the center of the spherical surface of the workpiece 2.

[0103] In some embodiments, the driving member 130 is connected to the supporting mechanism 110 away from the adsorption member 120 , so as to improve the space utilization rate of the supporting mechanism 110 for carrying the workpiece 2 .

[0104] See also Figure 1 The driving member 130 includes a motor 1310 and a transmission belt 1320. The motor 1310 is connected to the support mechanism 110 via the transmission belt 1320 to drive the support mechanism 110 to rotate. In this way, the motor 1310 is convenient to output a uniform rotation speed, and driving the support mechanism 110 by transmission is conducive to improving the stability of the rotation movement.

[0105] In some embodiments, the support mechanism 110 includes a connecting rod 1130 , a central axis of the connecting rod 1130 coincides with the predetermined axis L, and a transmission belt 1320 is connected to the connecting rod 1130 .

[0106] See also Figure 1 In some embodiments, the grinding seat 10 further includes a loading mechanism 160, and the loading mechanism 160 is used to load the supporting mechanism 110 and the driving member 130. In some embodiments, the loading mechanism 160 includes a loading plate 1610, a first supporting member 1110 and a second supporting member 1120 of the supporting mechanism 110 are arranged on one side of the loading plate 1610, and the driving member 130 is arranged on the other side of the loading plate 1610, and the connecting rod 1130 of the supporting mechanism 110 passes through the loading plate 1610 to be connected with the driving member 130. There is a gap between the connecting rod 1130 of the supporting mechanism 110 and the loading plate 1610, so that the driving member 130 can drive the supporting mechanism 110. The motor 1310 of the driving member 130 is fixedly arranged with the loading plate 1610. In this way, it is beneficial to reduce the vibration of the motor 1310 when it is working, thereby reducing the undesirable shaking of the supporting mechanism 110 when grinding the workpiece 2, and improving the quality of the workpiece 2 after grinding.

[0107] See also Figure 3 The present application also discloses a grinding device 1, which includes the aforementioned grinding seat 10, a grinding assembly 30 and a movable assembly 20. The grinding seat 10 is used to carry a workpiece 2 to be ground, the grinding assembly 30 is used to grind the workpiece 2, and the movable assembly 20 is used to adjust the position of the grinding assembly 30.

[0108] Please refer to Figure 3 and Figure 4 The movable assembly 20 includes a base 210 and a movable arm 220, and the movable arm 220 is movably connected to the base 210. The grinding assembly 30 includes a mounting seat 310 and a grinding head 320, and the grinding head 320 is disposed on the mounting seat 310.

[0109] In some embodiments, the grinding head 320 can rotate 360 ​​degrees, so that the workpiece 2 can be ground.

[0110] See also Figure 4 In some embodiments, the mounting seat 310 and the movable arm 220 are movably connected via an elastic component 40. In this way, when the position of the grinding component 30 is adjusted by the movable component 20, if the force applied by the grinding component 30 to the workpiece 2 is large, the elastic component 40 is conducive to storing a part of the force as elastic potential energy, and then gradually releasing the elastic potential energy, thereby facilitating the reduction of partial over-grinding of the workpiece 2, thereby facilitating the improvement of the quality of the workpiece 2 after grinding.

[0111] In some embodiments, the elastic member 40 is a spring.

[0112] In some embodiments, there may be a plurality of elastic components 40, such as two, so as to facilitate reasonable arrangement of the plurality of elastic components 40 according to the required elastic force.

[0113] See also Figure 3 The movable arm 220 includes a first arm 2210 connected to the base 210, and the first arm 2210 can rotate relative to the base 210 in a first plane P1. The movable arm 220 also includes a second arm 2220 connected to the first arm 2210, and the second arm 2220 can rotate relative to the first arm 2210 in a second plane P2. The movable arm 220 also includes a third arm 2230 connected to the second arm 2220, and the third arm 2230 can rotate relative to the second arm 2220 in the second plane P2. The movable arm 220 also includes a fourth arm 2240 connected to the third arm 2230, and the fourth arm 2240 can rotate relative to the third arm 2230 in a third plane P3. The movable arm 220 also includes a fifth arm 2250 connected to the fourth arm 2240, and the grinding assembly 30 is connected to the fifth arm 2250, and the fifth arm 2250 can rotate relative to the fourth arm 2240 in a fourth plane P4. The second plane P2 is perpendicular to the first plane P1, the third plane P3 is perpendicular to the second plane P2, and the fourth plane P4 is perpendicular to the third plane P3. In this way, by sequentially connecting and rotatable first arm 2210, second arm 2220, third arm 2230, fourth arm 2240 and fifth arm 2250, the flexibility of the movable arm 220 is improved, thereby facilitating the adjustment of the position of the grinding assembly 30.

[0114] In some embodiments, see Figure 4 The movable assembly 20 further includes a fixing block 2260 , which is disposed on the fifth arm 2250 , and the mounting seat 310 is movably connected to the fixing block 2260 via an elastic component 40 .

[0115] In some embodiments, the fixing block 2260 has a receiving space for receiving the elastic component 40 and a portion of the mounting seat 310. One side of the receiving space is connected to the elastic component 40, and the other side is in contact with a portion of the mounting seat 310. In this way, the elastic component 40 is confined within the receiving space, thereby improving the stability of the connection between the mounting seat 310 and the fixing block 2260 when the elastic component 40 is subjected to a force.

[0116] In some embodiments, the elastic component 40 is in a compressed state. Thus, the elastic component 40 in a compressed state has a certain elastic force. If the grinding assembly 30 applies a large force to the workpiece 2, the elastic component 40 can resist a part of the force without causing a large deformation, thereby further improving the stability of the connection between the mounting seat 310 and the fixing block 2260 when the elastic component 40 is subjected to the force. In other embodiments, the elastic component 40 is in a stretched state.

[0117] Please refer to Figure 4 and Figure 5 In some embodiments, the mounting seat 310 and the movable arm 220 are also movably connected via a rigid component 50, and the mounting seat 310 can move relative to the movable arm 220 along the rigid component 50. In this way, the rigid component 50 is helpful to guide the deformation direction of the elastic component 40, thereby helping to reduce the undesired swing of the grinding head 320 caused by the deformation of the elastic component 40. In some embodiments, the mounting seat 310 is movably connected to the movable arm 220 through the rigid component 50 and the fixed block 2260.

[0118] In some embodiments, see Figure 5 The mounting seat 310 has a through hole 3110, the rigid component 50 passes through the through hole 3110, and the two ends of the rigid component 50 are respectively fixed to the two sides of the accommodation space of the fixing block 2260, and there is a gap between the rigid component 50 and the through hole 3110. In this way, it is beneficial to make the mounting seat 310 move along the direction defined by the rigid component 50.

[0119] In some embodiments, the rigid member 50 is a pin.

[0120] In some embodiments, the rigid component 50 is sleeved in the elastic component 40. This helps to reduce the space occupied by the rigid component 50, thereby improving the compactness of the grinding device 1.

[0121] In some embodiments, the number of rigid components 50 is the same as the number of elastic components 40 .

[0122] In some embodiments, see Figure 4 The grinding device 1 further includes a detection component 60, which is disposed on the fifth arm 2250 of the movable arm 220 and is used to detect the concentricity of the spherical surface of the workpiece 2 after grinding. In this way, it is helpful to identify the workpiece 2 after grinding as a good product or a defective product according to the detection situation, so as to facilitate the placement of the workpiece 2 after grinding into different areas for the convenience of subsequent processes.

[0123] In some embodiments, the detection component 60 includes a CCD camera, and the CCD camera and the fixing block 2260 are arranged relative to the fifth arm 2250.

[0124] In the above-mentioned grinding device 1, the workpiece 2 is first placed on the first support member 1110 of the support mechanism 110, and then the second support member 1120 of the support mechanism 110 is fixed to the first support member 1110, so as to support the inner and outer surfaces of the workpiece 2, thereby reducing the edge collapse of the workpiece 2 during the grinding process. Then the adsorption member 120 adsorbs and fixes the workpiece 2, thereby improving the stability of the workpiece 2 fixed to the support mechanism 110. Then the driving member 130 drives the support mechanism 110 to rotate around the predetermined axis L, thereby driving the workpiece 2 fixed to the support mechanism 110 to rotate. At the same time, the grinding head 320 also starts to rotate, and the movable arm 220 adjusts the position of the grinding head 320 to grind the workpiece 2. After the grinding is completed, the detection component 60 detects the concentricity of the spherical surface of the workpiece 2 after grinding, and identifies the workpiece 2 as a good product or a defective product, so that the workpiece 2 is placed in different areas for subsequent processes.
