[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.
[0033] As mentioned in the background, in polishing equipment, the active and passive rockers are mounted with driven rollers and spherical screws, respectively. The contact between the driven rollers and spherical screws allows the active rocker to drive the passive rocker in a reciprocating motion. However, this contact is point contact, which can easily cause the spherical screw to wear during motion. This, in turn, requires frequent adjustment of the spherical screw, negatively impacting the grinding process.
[0034] Please refer to Figure 1 and Figure 2 The swing gear transmission polishing grinding head 100 and polishing equipment provided in the embodiment of the present invention can solve the above problems, which will be described in detail below.
[0035] The pendulum gear transmission type polishing grinding head 100 includes a driving member 110, a cam 120, an active pendulum rod 130, a driven pendulum rod 140 and a grinding block 150;
[0036] Among them, the cam 120 is connected to the driving member 110 in a transmission manner, the active rocker arm 130 cooperates with the cam 120, the active rocker arm 130 is provided with an active rocker tooth 131, and the driven rocker arm 140 is provided with a driven rocker tooth 141, the active rocker tooth 131 is meshed with the driven rocker tooth 141, and the active rocker arm 130 is provided with a grinding block 150 in a one-to-one correspondence, and the driven rocker arm 140 is provided with a grinding block 150 in a one-to-one correspondence.
[0037] During operation, the driving member 110 can drive the cam 120 to rotate, and the contact between the cam 120 and the active rocker arm 130 drives the active rocker arm 130 to swing, and the cooperation between the active rocker arm 131 and the driven rocker arm 141 realizes the swing transmission between the active rocker arm 130 and the driven rocker arm 140. The cooperation contact is more stable and less prone to wear, which can reduce the adjustment frequency and reduce the negative impact on the grinding operation.
[0038] It is worth noting that there are multiple grinding blocks 150, and each grinding block 150 can correspond to one active swing rod 130 or one passive swing rod 140. That is, when the active swing rod 130 swings, it can drive the corresponding grinding block 150 to move synchronously; similarly, when the passive swing rod 140 swings, it can also drive the corresponding grinding block 150 to move synchronously.
[0039] Furthermore, the grinding block 150 is detachably connected to the active swing arm 130 and the driven swing arm 140. This allows for quick and easy replacement of the grinding block 150 when the grinding block 150 becomes excessively worn. Furthermore, when the workpiece changes, the grinding block 150 corresponding to the workpiece can be replaced, thereby increasing the versatility of the overall swing-tooth drive polishing grinding head 100.
[0040] refer to Figure 2 The number of active rocker arms 130 and driven rocker arms 140 is at least two, and at least two active rocker arms 130 and at least two driven rocker arms 140 are alternately arranged in sequence, that is, the active rocker teeth 131 and the driven rocker teeth 141 are also alternately arranged in sequence, thereby improving the transmission stability.
[0041] It is worth noting that the alternating arrangement can be understood as both sides of an active rocker arm 130 are followed by a driven rocker arm 140. Similarly, both sides of a driven rocker arm 140 are followed by an active rocker arm 130, that is, the arrangement is in the order of an active rocker arm 130, followed by a driven rocker arm 140, followed by an active rocker arm 130, and then followed by a driven rocker arm 140...
[0042] In addition, at least two active rocking rods 130 and at least two driven rocking rods 140 are arranged in an enclosed manner, that is, the active rocking tooth 131 and the driven rocking tooth 141 are also arranged in an enclosed manner. The same active rocking tooth 131 will engage with two driven rocking teeth 141 at the same time, and the same driven rocking tooth 141 will also engage with the same active rocking tooth 131, thereby forming a closed loop, which can further improve the transmission stability.
[0043] In this embodiment, the number of the active rocker rods 130 and the number of the driven rocker rods 140 are both three, that is, the number of the active rocker teeth 131 and the number of the driven rocker teeth 141 are also three; of course, in other embodiments of the present invention, the number of the active rocker rods 130, the active rocker teeth 131, the driven rocker rods 140 and the driven rocker teeth 141 can also be two, four, seven, etc., and there is no limitation on the specific number of settings.
[0044] refer to Figure 1 The driving member 110 includes a main shaft 111, a coupling 112, a grinding head seat 113 and a sleeve 114. The coupling 112 is used to connect the main shaft 111 and the grinding head seat 113. The sleeve 114 is connected to the grinding head seat 113 and is sleeved on the main shaft 111. The cam 120 is connected to the sleeve 114 through transmission.
[0045] During operation, the main shaft 111 can drive the grinding head seat 113 to rotate synchronously through the coupling 112 . The shaft sleeve 114 is sleeved on the main shaft 111 to protect the main shaft 111 and also rotates synchronously with the grinding head seat 113 .
[0046] It is worth noting that both the active swing arm 130 and the driven swing arm 140 can be movably connected to the grinding head base 113. Even if the active and driven swing arms 130, 140 rotate at different frequencies than the grinding head base 113, the movably connected swing arms can still provide improved support for the two swing arms. The specific connection location can be the fulcrum of the swing, thereby improving the swing stability of the active and driven swing arms 130, 140 through the grinding head base 113.
[0047] Furthermore, in order to improve the support strength of the main shaft 111 and the grinding head seat 113 , the driving member 110 may further include a joint bearing 115 , which is disposed between the main shaft 111 and the grinding head seat 113 .
[0048] refer to Figure 3 In order to improve the shock absorption performance and avoid excessive vibration during the rotation process, the driving member 110 may further include a buffer pad 116, which is arranged between the coupling 112 and the grinding head seat 113.
[0049] Specifically, the buffer pad 116 can include a large rubber pad and a small rubber pad. The large rubber pad is arranged on one end of the coupling 112 close to the sleeve 114 and is located on the inner side of the grinding head seat 113; the small rubber pad is arranged at the threaded connection between the coupling 112 and the grinding head seat 113, thereby buffering and reducing shock at multiple positions between the coupling 112 and the grinding head seat 113.
[0050] refer to Figure 1 The swing gear transmission polishing grinding head 100 also includes a transmission member 160, which includes a driving gear 161, a transmission gear 162 and a driven gear 163 that are meshed in sequence. The driving gear 161 is sleeved on the shaft sleeve 114, and the cam 120 is sleeved on the driven gear 163. The number of teeth of the driving gear 161 and the driven gear 163 are different.
[0051] Since there is a difference in the number of teeth between the driving gear 161 and the driven gear 163 , differential transmission is achieved between the main shaft 111 and the cam 120 , thereby enabling the grinding block 150 to swing at a normal frequency, thereby better completing the grinding operation.
[0052] refer to Figure 1 and Figure 2 In order to improve the transmission smoothness between the active rocker arm 130 and the cam 120 , the active rocker arm 130 may be connected to a roller 132 , and the roller 132 cooperates with the cam 120 .
[0053] It is worth noting that the side of the cam 120 close to the active rocker arm 130 is a curved surface with crests and troughs. The roller 132 can contact the crests and troughs in an orderly manner, thereby driving the active rocker arm 130 to swing.
[0054] In this embodiment, a connecting frame 133 is provided on the active rocker arm 130, and rollers 132 are provided at both ends of the connecting frame 133. When the roller 132 at one end of the connecting frame 133 contacts the peak point of the cam 120, the roller 132 at the other end may contact the trough point of the cam 120. After the cam 120 rotates a certain angle, the contact positions at the two ends are exchanged, thereby driving the active rocker arm 130 to swing.
[0055] An embodiment of the present invention also provides a polishing device, including a swing gear transmission polishing grinding head 100, a power source and a control box, the control box is used to be electrically connected to various electrical components, the power source is used to be connected to the main shaft 111 in the driving member 110 of the swing gear transmission polishing grinding head 100, and the power source is used to provide power to drive the main shaft 111 to rotate.
[0056] It is worth noting that the power source can specifically be a rotating motor, a rotating cylinder or a rotating hydraulic cylinder, and there is no limitation on the specific power form.
[0057] In summary, the swing gear drive polishing grinding head 100 and polishing equipment provided by the embodiments of the present invention have at least the following advantages:
[0058] (1) It can realize the swing transmission between the active swing rod 130 and the driven swing rod 140 through the cooperation of the active swing tooth 131 and the driven swing tooth 141. The cooperation contact is more stable and less prone to wear, thereby reducing the adjustment frequency and reducing the negative impact on the grinding operation.
[0059] (2) By setting a joint bearing 115 between the main shaft 111 and the grinding head seat 113, on the one hand, the support strength of the main shaft 111 and the grinding head seat 113 can be improved, and on the other hand, the rotation smoothness of the two can be ensured.
[0060] (3) It is possible to provide a buffer pad 116 between the coupling 112 and the grinding head seat 113, and improve the shock absorption performance of the two at multiple positions and multiple directions through the buffer pad 116, so as to make the grinding operation of the integral swing gear transmission polishing grinding head 100 more stable.
[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
