DETAILED DESCRIPTION

[0048] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0049] like Figure 1 The schematic diagram of the flip positioning device according to the preferred embodiment of the present invention is shown, which is used to drive the workpiece 200 to flip, so as to realize the processing of at least two surfaces to be processed of the workpiece 200 at the same station, effectively improving the work efficiency. The workpiece 200 includes a support arm or a wheel hub, etc. Of course, the workpiece 200 can be a connecting member, and the connecting member is used to connect the wheel hub, etc., wherein the wheel hub is detachably mounted on the connecting member, and the wheel hub connected to the connecting member is driven to rotate by the flip positioning device 100 to process at least two surfaces to be processed of the wheel hub.

[0050] like Figures 1 to 4 As shown, a flip positioning device 100 includes:

[0051] A flip connector 110, comprising at least one connecting plate 111, each connecting plate 111 is provided with a first through hole 1111;

[0052] At least one flip support assembly 120, each flip support assembly 120 is respectively arranged opposite to a connecting plate 111, including a fixed member 121, a first rotating member 122, a second rotating member 123 and a top shaft 124, the first rotating member 122 is rotatably connected to the outside of the fixed member 121, and the first rotating member 122 is connected to the connecting plate 111, a top shaft 124 is slidably arranged inside the fixed member 121, and the top shaft 124 is rotatably connected to the second rotating member 123 on one end facing the connecting plate 111, and the second rotating member 123 can move with the top shaft 124 and pass through the first through hole 1111, wherein the top shaft 124 moves along its axial direction;

[0053] A driving assembly 130 is drivingly connected to the first rotating member 122 .

[0054] The flip positioning device is used to drive the workpiece 200 to flip, and the workpiece 200 is provided with a sleeve hole that cooperates with the second rotating member 123. When installing the workpiece 200, first fix the workpiece 200 on the flip connection member 110, and make the sleeve hole on the workpiece 200 and the first through hole 1111 arranged oppositely. At this time, the workpiece 200 is located on the side of the connecting plate 111 away from the flip support assembly 120, and then manually or electrically push the top shaft 124 so that the second rotating member 123 on the top shaft 124 passes through the first through hole 1111 and is inserted into the sleeve hole to achieve the positioning function. Thereafter, the driving assembly 130 drives the first rotating member 122 to rotate, and the first rotating member 122 drives the flip connection member 110 and the workpiece 200 to rotate around the axis direction of the top shaft 124. When disassembling the workpiece 200, push the top shaft 124 to move in the opposite direction and make the second rotating member 123 slide out of the sleeve hole, and then remove the workpiece 200.

[0055] By adopting the above structure, the top shaft 124 can cooperate with the workpiece 200 and can make the workpiece 200 rotate around the axis direction of the top shaft 124. It can be seen that when the workpiece 200 rotates, it is matched and connected with the top shaft 124, which effectively prevents the workpiece 200 from falling during the rotation process and improves the stability and safety of the rotation of the workpiece 200. In addition, the movement process of the top shaft 124 can be carried out manually or electrically, with a variety of options, making the operation more convenient and further improving efficiency.

[0056] like Figure 3 and Figure 4As shown, the flip support assembly 120 also includes a locking member 125 for locking and unlocking the top shaft 124 so that the top shaft 124 and the workpiece 200 can be fixed after being matched, thereby preventing the top shaft 124 from being separated during the rotation of the workpiece 200 and affecting the use effect.

[0057] Specifically, the locking member 125 includes a limit sleeve 1251 and a handle 1252. The limit sleeve 1251 is arranged on the side of the fixing member 121 away from the first rotating member 122. The limit sleeve 125 is hollow inside so that the top shaft 124 can slide inside the limit sleeve 125, that is, the top shaft 124 is slidably arranged inside the limit sleeve 125. A limit hole 12511 is arranged on the limit sleeve 1251, and a handle 1252 cooperating with the limit hole 12511 is arranged on the top shaft 124. The handle 1252 is located at one end of the top shaft 124 away from the second rotating member 123.

[0058] When the second rotating member 123 on the top shaft 124 is inserted into the sleeve hole of the workpiece 200, the handle 1252 and the limiting hole 12511 are arranged opposite to each other. By rotating the top shaft 124, the handle 1252 can be clamped in the limiting hole 12511 to achieve the purpose of locking the workpiece 200. When the second rotating member 123 needs to be removed from the sleeve hole, the top shaft 124 is rotated in the opposite direction by the handle 1252 to move the handle 1252 out of the limiting hole 12511 to achieve the purpose of unlocking the workpiece. At this time, the top shaft 124 can be pulled out by the handle 1252.

[0059] It should be noted that, after the locking member 125 locks the workpiece, the driving assembly 130 drives the first rotating member 122 to rotate. In this process, since the second rotating member 123 and the top shaft 124 are rotatably connected, the workpiece 200 can rotate relative to the top shaft 124 and along with the first rotating member 122, that is, the top shaft 124 is fixed at this time.

[0060] More specifically, the handle 1252 and the top shaft 124 are arranged vertically. The top shaft 124 is cylindrical, and the limiting sleeve 1251 is C-shaped and can be sleeved on the outside of the top shaft 124. The C-shaped limiting sleeve 1251 can avoid the handle 1252 and make the top shaft 124 move relative to the limiting sleeve 1251.

[0061] In one embodiment, the handle 1252 and the top shaft 124 are telescopically connected.

[0062] In another embodiment, the handle 1252 and the top shaft 124 are threadedly connected.

[0063] like Figures 2 to 4As shown, the fixing member 121 includes a supporting base 1211 and a sleeve 1212. The supporting base 1211 is fixedly arranged on one side of the connecting plate 111, and is provided with a second through hole 12111 arranged opposite to the first through hole 1111. The top shaft 124 is slidably arranged in the second through hole 12111. The sleeve 1212 is arranged on the supporting base 1211 and is located on the side of the supporting base 1211 facing the connecting plate 111. The sleeve 1212 is hollow inside, and the inside of the sleeve 1212 is opposite to the second through hole 12111, so that the top shaft 124 can pass through and slide with the fixing member 121.

[0064] The support base 1211 and the sleeve 1212 can be connected by fasteners, and the fasteners include screws and bolts. Figure 3 A countersunk hole 12112 is provided on the side of the support base 1211 away from the sleeve 1212, so that the head of the screw or the like is embedded in the countersunk hole 12112 to prevent the head of the screw from affecting the installation of other parts, such as the limiting sleeve 1251. Specifically, the limiting sleeve 1251 is provided on the side of the support base 1211 away from the sleeve 1212, and the limiting sleeve 1251 can also be fixed to the support base 1211 by fasteners. Among them, a slideway for sliding the top shaft 124 is formed inside the limiting sleeve 1251, between the second through hole 12111 and the inside of the sleeve 1212, so that the top shaft 124 can slide.

[0065] like Figure 3 and Figure 4 As shown, the support base 1211 is provided with a first positioning groove 12113 that cooperates with the sleeve 1212, and the second through hole 12111 is located in the first positioning groove 12113. By providing the first positioning groove 12112, when the support base 1211 and the sleeve 1212 are connected, the second through hole 12111 and the inside of the sleeve 1212 are opposite to each other, so as to prevent assembly errors from affecting the sliding connection between the top shaft 124 and the fixing member 121. Specifically, the first positioning groove 12113 and the second through hole 12111 are both circular, and the two are coaxially arranged. At this time, the end of the sleeve 1212 that cooperates with the first positioning groove 12112 is also circular.

[0066] like Figure 3 to Figure 4 As shown, the first rotating member 122 includes an outer shaft seat 1221 , which is rotatably disposed outside the sleeve 1212 and connected to the connecting plate 111 .

[0067] Furthermore, the first rotating member 122 further includes a first positioning plate 1224 , two sides of which are respectively connected to the connecting plate 111 and the outer shaft seat 1221 , and the first positioning plate 1224 is a hollow structure to allow the second rotating member 123 and the top shaft 124 to pass through.

[0068] refer to Figure 2, the connecting plate 111 is provided with a second positioning groove 1112 matched with the first positioning disc 1224, and the first through hole 1111 is located inside the second positioning groove 1112. By providing the second positioning groove 1112, the installation positioning accuracy is improved, and the assembly error is effectively prevented from affecting the use of the flip positioning device 100. Specifically, the second positioning groove 1112 and the first through hole 1111 are both circular and coaxially arranged, and the first positioning disc 1224 matched with the second positioning groove 1112 is annular.

[0069] In one embodiment, the first rotating member 122 and the driving assembly 130 are connected via a belt drive.

[0070] In another embodiment, the first rotating member 122 and the driving assembly 130 are connected by gear transmission. Specifically, the first rotating member 122 includes a first gear 1225 that cooperates with the driving assembly 130 to achieve transmission connection between the two. The first gear 1225 is arranged between the first positioning plate 1224 and the outer shaft seat 1221, and the first gear 1225 is hollow inside to allow the top shaft 124 to pass through. The connecting plate 111, the first positioning plate 1224, the first gear 1225 and the outer shaft seat 1221 can be connected by fasteners.

[0071] Furthermore, the first rotating member 122 further includes a first bearing 1222 and a first retaining spring 1223 . The first bearing 1222 is sleeved between the sleeve 1212 and the outer shaft seat 1221 , and is locked by the first retaining spring 1223 , so that the outer shaft seat 1221 can rotate relative to the sleeve 1212 .

[0072] Furthermore, the first gear 1225 can be a sector gear. By increasing the number of the first bearings 1222, the sector gear with greater force can be supported. Specifically, the number of the first bearings 1222 and the number of the first retaining springs 1223 are two respectively.

[0073] like Figure 3 and Figure 4 As shown, a second bearing 126 is sleeved between the top shaft 124 and the second rotating member 123. Preferably, the number of the second bearings 126 is two.

[0074] Furthermore, the second rotating member 123 is an annular structure, and a head 127 and a second retaining spring 128 are respectively disposed at both ends of the second rotating member 123 to position the second bearing 127 inside the second rotating member 123. The head 127 is located on the side of the second rotating member 123 away from the top shaft 124.

[0075] like Figure 1 , Figure 3 and Figure 5As shown, the driving assembly 130 includes a motor 131 and a second gear 132, the motor 131 and the second gear 132 are in transmission connection, and the second gear 132 is meshed with the first gear 1225. In this way, the motor drives the second gear 132 to rotate, the second gear 132 drives the first gear 1225 to rotate, and the first gear 1225 drives the flip connector 110 and the workpiece 200 to rotate.

[0076] like Figure 1 and Figure 2 As shown, the number of the flip support assembly 120 and the number of the connecting plates 111 are two respectively, and each connecting plate 111 corresponds to one flip support assembly 120 .

[0077] Specifically, the flip connector 110 further includes a mounting plate 112, two connecting plates 111 are respectively arranged on opposite sides of the mounting plate 112, and the first through holes 1111 on the two connecting plates 111 are arranged opposite to each other. The mounting plate 112 is used to mount the workpiece 200. After the workpiece 200 is mounted on the mounting plate 112, the workpiece 200 is located between the two connecting plates 111, and two sleeve holes are arranged on the workpiece 200, each sleeve hole corresponds to a first through hole 1111, so that the flip support assembly 120 can position the sleeve holes. Figure 3 and Figure 4 , and then the top shafts 124 on both sides of the workpiece 200 can be pushed so that the second rotating member 123 on the top shaft 124 is inserted into the corresponding sleeve hole and locked by the locking member 125. It should be noted that the top shafts 124 on both sides are coaxially arranged so that the driving assembly 130 drives the workpiece 200 to rotate around the axis of the top shaft 124.

[0078] like Figure 1 and Figure 6 As shown, the flip positioning device 100 also includes:

[0079] A transmission assembly 140, the driving assembly 130 is connected to the two flip support assemblies 120 through the transmission assembly 140. The transmission assembly 140 can drive the two flip support assemblies 120 to rotate at the same time.

[0080] Specifically, refer to Figure 1 , Figure 3 , Figure 5 and Figure 6The transmission assembly 140 includes a transmission shaft 141, a third gear 142, two fourth gears 143 and two first mounting seats 144. The first mounting seats 144 are rotatably provided at both ends of the transmission shaft 141. The first mounting seats 144 can be fixed on a workbench or a bracket to fix the transmission assembly 140. The third gear 142 and the fourth gear 143 are sleeved on the transmission shaft 141. The third gear 142 is meshed with the second gear 132, and each fourth gear 143 is meshed with the first gear 1225. The motor 131 drives the second gear 132 to rotate, the second gear 132 drives the third gear 142 to rotate, the third gear 142 drives the transmission shaft 141 and the fourth gear 143 to rotate, and each fourth gear 143 drives the first gear 1225 to rotate, thereby realizing that the driving assembly 130 drives the two flip support assemblies 120 to rotate at the same time.

[0081] More specifically, a bearing is sleeved between the first mounting seat 144 and the transmission shaft 141 .

[0082] In one embodiment, the third gear 142 is located between the two fourth gears 143. Further, the two first mounting seats 144 are located between the two fourth gears 143 and on both sides of the third gear 142. A pressure cover 145 is provided on the side of the fourth gear 143 away from the first mounting seat 144.

[0083] In another embodiment, the third gear 142 is located between two fourth gears 143 , and the two fourth gears 143 are located between two first mounting seats 144 .

[0084] like Figure 1 , Figure 2 and Figure 6 As shown, the transmission assembly 140 is located at the lower part of the mounting plate 112, and the mounting plate 112 is provided with an avoidance hole 1121 for avoiding the rotation of the third gear 142. At this time, the workpiece 200 is located at the upper part of the mounting plate 112.

[0085] like Figure 5 As shown, the driving assembly 130 also includes a reducer 133 and a second mounting seat 134 , the motor 131 and the reducer 133 are transmission connected, the reducer 133 is mounted on the second mounting seat 134 , and the second gear 132 is sleeved on the output shaft of the reducer 133 .

[0086] refer to Figure 5 The driving assembly 130 further includes two third mounting seats 135, which are rotatably connected to the output shaft of the reducer 133 and are located on the side of the third mounting seats 135 away from the reducer 133. Specifically, a bearing is provided between each third mounting seat 135 and the output shaft of the reducer 133.

[0087] In one example, the second gear 132 is located between two third mounting seats 135 .

[0088] The second mounting seat 134 and the third mounting seat 135 mentioned above can be installed on a workbench or a bracket to fix the driving assembly 130 .

[0089] Continue to refer Figure 5 and Figure 2 The driving assembly 130 is located at the lower part of the mounting plate 112 and at one side of the mounting plate 112 where the avoidance hole 1121 is arranged.

[0090] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the flip positioning device 100 further includes a second positioning plate 150, which is disposed on the side of the mounting plate 112 away from the avoidance hole 1121, so that the workpiece 200 is fixed on the mounting plate 112 through the second positioning plate 150. In this way, when the workpiece 200 is mounted on the mounting plate 112, the two sleeve holes on the workpiece 200 can be aligned with the second rotating member 123 on the top shaft 124, thereby improving the mounting accuracy.

[0091] Specifically, the mounting plate 112 is provided with a third positioning groove 1122, which is located on the side of the mounting plate 112 away from the avoidance hole 1121. The second positioning plate 150 cooperates with the third positioning groove 1122 to achieve positioning and installation of the workpiece 200 on the mounting plate 112. In one example, the second positioning plate 150 and the third positioning groove 1122 are both circular.

[0092] More specifically, a mounting groove 151 is provided on a side of the second positioning plate 150 facing the workpiece 200 , and the workpiece 200 can be embedded in the mounting groove 151 and fixed by a fastener.

[0093] After one surface of the workpiece 200 to be processed is processed, the workpiece 200 can be rotated by the flip positioning device 100 so that the other surface of the workpiece 200 to be processed is located at the processing station. The principle of the flip positioning device 100 is as follows:

[0094] In the first step, the two top shafts 124 are pushed to move toward the workpiece 200 respectively, so that the second rotating member 123 on the top shaft 124 is inserted into the sleeve hole on the workpiece 200, and then the handle 1252 on the top shaft 124 is rotated and clamped in the limiting hole 12511 on the limiting sleeve block 1251, so as to lock the top shaft 124 and realize the purpose of positioning the workpiece by the top shaft 124.

[0095] In the second step, the motor 131 drives the second gear 132 to rotate through the reducer 133, and the second gear 132 drives the third gear 142 to rotate. The two fourth gears 143 rotate simultaneously with the second gear 132, and each fourth gear 143 drives a first gear 1225 to rotate, so that the flip connector 110 and the workpiece 200 rotate along the axis direction of the top shaft 124 until the surface to be processed of the workpiece 200 is at the processing station, at which time the surface to be processed of the workpiece 200 can be processed.

[0096] After the processing is completed, the handles 1252 on the two top shafts 124 can be rotated to move the handles 1252 out of the limiting holes 12511 on the limiting sleeve 1251 to achieve the purpose of unlocking the top shaft 124. At this time, the top shaft 124 is pushed away from the workpiece 200 to make the second rotating member 123 on the top shaft 124 move out of the sleeve hole to facilitate the disassembly and assembly of the workpiece 200.

[0097] It should be noted that after the workpiece 200 mounted on the mounting plate 112 completes the processing of one surface to be processed, the workpiece 200 is driven to rotate by the flip positioning device 100 so that another surface to be processed of the workpiece 200 is located at the work station. It can be seen that the workpiece 200 may have multiple surfaces to be processed, and the rotation angle is controlled by the motor 131 so that different surfaces to be processed of the workpiece 200 are located at the work station. In one example, the motor 131 drives the workpiece 200 to rotate 30° to process the surface to be processed of the workpiece 200 located at the work station. In another example, the workpiece 200 has two surfaces to be processed, and the two surfaces to be processed are located on the front and back sides of the workpiece 200, respectively. At this time, the motor 131 controls the workpiece 200 to rotate 90°.
