[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] In one embodiment, Figure 1-Figure 8 As shown, an auxiliary tooling for centering check of tire bead suction claws of a forming machine comprises an auxiliary tooling mechanism 1, a forming drum 2, a tire bead suction claw body 3 and a base 4, wherein the auxiliary tooling mechanism 1 comprises a mounting disc 101, a magnetic block 102 is attached to one side of the outer side of the mounting disc 101, a first mounting hole 103 is provided at the center point of one side of the magnetic block 102, a first threaded hole 104 is provided at one side of the mounting disc 101 corresponding to the first mounting hole 103, a first screw 105 penetrates one side of the magnetic block 102 through the first mounting hole 103, and the first screw 105 is threadedly connected to the mounting disc 101 through the first threaded hole 104, a positioning groove 15 is provided at the center point of one side of the forming drum 2, and the positioning groove 15 is adapted to the magnetic block 102, and a mounting assembly is provided on the other side of the mounting disc 101.

[0032] In this embodiment, when it is necessary to measure the alignment between the tire bead suction claw body 3 and the forming drum 2, the tire bead suction claw body 3 is moved to the outside of the forming drum 2, and the magnetic block 102 is aligned and placed into the inside of the positioning groove 15. Since the magnetic block 102 is magnetic, the auxiliary tooling mechanism 1 and the forming drum 2 are magnetically fixed. At this time, the alignment is measured by the auxiliary tooling mechanism 1. After long-term use, the magnetism of the mounting disc 101 decreases or the mounting disc 101 is damaged. At this time, the mounting disc 101 needs to be replaced. The first screw 105 is removed by a screwdriver, and the fixation of the magnetic block 102 and the mounting disc 101 is released. The first screw 105 is used to penetrate the new magnetic block 102 through the first mounting hole 103, and then the first screw 105 is threadedly installed on the mounting disc 101 through the first threaded hole 104, thereby fixing the magnetic block 102 and the mounting disc 101. The structure is simple, and there is no need to replace the entire auxiliary tooling mechanism 1 when it is damaged, thereby reducing the cost of use.

[0033] In one embodiment, Figure 3 As shown, the mounting assembly includes a measuring caliper 106, and the measuring caliper 106 is symmetrically attached to the other side of the outside of the mounting disc 101. A first mounting groove 107 adapted to the mounting disc 101 is opened on one side of the measuring caliper 106, and a second screw hole 108 is opened on one side of the first mounting groove 107. A second mounting hole 109 is opened on one side of the mounting disc 101 at a position corresponding to the second screw hole 108. A second screw 110 is penetrated through the second mounting hole 109 on the outside of the mounting disc 101, and the second screw 110 is threadedly connected to the measuring caliper 106 through the second screw hole 108. A slide groove 111 is provided inside, and a measuring component is provided inside the slide groove 111. When the measuring caliper 106 and the mounting disc 101 are installed, the mounting disc 101 is engaged with the measuring caliper 106 through the first mounting groove 107, and then the second screw 110 is used to penetrate the mounting disc 101 through the second mounting hole 109. The second screw 110 is rotated. Due to the setting of the second screw hole 108, the second screw 110 and the measuring caliper 106 are threadedly installed, thereby fixing the mounting disc 101 and the measuring caliper 106. When one of the measuring calipers 106 is damaged, the measuring caliper 106 can be quickly replaced by the above method, thereby improving practicality.

[0034] In one embodiment, Figure 4As shown, the measuring assembly includes a measuring plate 112, which is slidably mounted inside the slide groove 111, and a limiting groove 113 is provided on the other side of the measuring caliper 106. A slider 114 is slidably mounted on the other side of the measuring caliper 106 through the limiting groove 113, and the slider 114 and the measuring plate 112 are fixedly mounted. Scale lines 115 are equidistantly provided on the other side of the measuring caliper 106, and the scale lines 115 are located on one side of the limiting groove 113. A rotating assembly is provided on the other side of the mounting disc 101. When the measuring plate 112 is used alone for measurement, the gear 117 is slid outside the rotating rod 116 to release the engagement between the gear 117 and the rack 120. At this time, the slider 114 is pushed to drive the measuring plate 112 to move, and the measuring plate 112 is moved to fit with the tire bead suction claw body 3. At this time, the position of the scale line 115 where the slider 114 is located is read.

[0035] In one embodiment, Figure 6 As shown, the rotating assembly includes a rotating rod 116, which is rotatably mounted on the other side of the mounting disc 101. A gear 117 is sleeved on the outside of the rotating rod 116, and the gear 117 can slide on the outside of the rotating rod 116. A slot 118 matching the rotating rod 116 is provided on the outside of the gear 117. A knob 119 is fixedly mounted on one end of the rotating rod 116. When the two measuring plates 112 need to be moved together for measurement, the gear 117 is slid on the outside of the rotating rod 116 so that The gear 117 is meshed with the rack 120. At this time, the gear 117 can be driven to rotate by turning the knob 119. The rotation of the gear 117 drives the two racks 120 to move. The two racks 120 drive the two measuring plates 112 to move. One end of one of the measuring plates 112 is moved to fit with the tire bead suction claw body 3. After reading, one end of the other measuring plate 112 is moved to fit with the tire bead suction claw body 3. The operation is simple, and the centering degree of the tire bead suction claw body 3 on the forming drum 2 is obtained by calculating the difference between the left and right sides of the same horizontal plane.

[0036] In one embodiment, Figure 4 and Figure 5 As shown, linkage components are symmetrically arranged on the outside of the gear 117, and the two measuring plates 112 can be moved through the linkage components, thereby improving the measurement efficiency.

[0037] In one embodiment, Figure 5As shown, the linkage assembly includes a rack 120, which is symmetrically distributed on both sides of the outside of the gear 117, and the two racks 120 are meshed with the gear 117. One end of the two racks 120 is fixedly installed with the two sliders 114 respectively, and the two measuring plates 112 are driven to move together through the meshing of the gear 117 and the rack 120. The structure is stable and safe to use. At the same time, the meshing of the gear 117 and the rack 120 is released, and the two measuring plates 112 can be measured separately, which improves practicality.

[0038] In one embodiment, Figure 1 As shown, a fixing frame 5 is fixedly installed on one side of the top of the base 4, a second mounting groove 6 is opened on one side of the outside of the fixing frame 5, a first screw rod 7 is rotatably installed inside the second mounting groove 6, a first motor 8 is fixedly installed on the top of the fixing frame 5, and the output end of the first motor 8 is connected to the first screw rod 7, and the first screw rod 7 is driven to rotate by the operation of the first motor 8.

[0039] In one embodiment, Figure 1 and Figure 7 As shown, the external thread of the first screw rod 7 is connected to the lifting frame 9, and the interior of the lifting frame 9 is respectively fixedly installed with a driving motor 10 and a reduction box 11, the output end of the driving motor 10 is connected to the input end of the reduction box 11, and the output end of the reduction box 11 is connected to the molding drum 2. The rotation of the first screw rod 7 can change the height of the lifting frame 9, and then change the height of the molding drum 2. The driving motor 10 drives the reduction box 11 to work, and the reduction box 11 drives the molding drum 2 to rotate, so that the molding drum 2 contacts the feeding component of the molding machine, and the tire skin is attached to the outside of the molding drum 2.

[0040] In one embodiment, Figure 1 As shown, a third mounting groove 12 is opened on the other side of the top of the base 4, and a second screw rod 13 is rotatably installed inside the third mounting groove 12. A second motor 14 is fixedly installed on one side of the base 4, and the output end of the second motor 14 is connected to the second screw rod 13, and the second screw rod 13 is driven to rotate by the operation of the second motor 14.

[0041] In one embodiment, Figure 1 As shown, the tire bead suction claw body 3 is threadedly connected to the second screw rod 13, and the tire bead suction claw body 3 is slidably installed with the base 4 along the length direction of the second screw rod 13 through the third installation groove 12. The second screw rod 13 rotates to make the tire bead suction claw body 3 slide on the top of the base 4, thereby changing the position of the tire bead suction claw body 3, so that the tire bead suction claw body 3 moves to the outside of the forming drum 2, and the tire being processed is clamped and transported to the next step of processing through the tire bead suction claw body 3.

[0042] The working principle of the present invention is: during the use of the molding machine, it is necessary to adjust the alignment between the molding drum 2 and the tire bead suction claw body 3 to ensure that the tire bead suction claw body 3 can intactly clamp and remove the tire from the outside of the molding drum 2, so the horizontal center lines of the molding drum 2 and the tire bead suction claw body 3 must coincide with each other. When measuring the alignment, the second motor 14 drives the second screw rod 13 to rotate, and the rotation of the second screw rod 13 causes the tire bead suction claw body 3 to slide on the top of the base 4, thereby changing the position of the tire bead suction claw body 3, so that the tire bead suction claw body 3 moves to the outside of the molding drum 2, and aligns the magnetic suction block 102 into the inside of the positioning groove 15. Since the magnetic suction block 102 is magnetic, the auxiliary tooling mechanism 1 is magnetically fixed to the molding drum 2.

[0043] When it is necessary to move the two measuring plates 112 together for measurement, slide the gear 117 on the outside of the rotating rod 116 so that the gear 117 is engaged with the rack 120. At this time, the gear 117 can be driven to rotate by turning the knob 119. The rotation of the gear 117 drives the two racks 120 to move, and the two racks 120 drive the two measuring plates 112 to move. Move one end of one of the measuring plates 112 to fit with the tire bead suction claw body 3. After reading, move one end of the other measuring plate 112 to fit with the tire bead suction claw body 3. This operation is simple, and the degree of centering of the tire bead suction claw body 3 on the forming drum 2 is obtained by calculating the difference between the left and right sides of the same horizontal plane.

[0044] If the two measuring plates 112 are to be used separately, the gear 117 is slid outside the rotating rod 116 to release the meshing of the gear 117 and the rack 120. At this time, the slider 114 is pushed to move the measuring plate 112, and the measuring plate 112 is moved to fit with the tire bead suction claw body 3. At this time, the position of the scale line 115 where the slider 114 is located is read, thereby improving practicality.

[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
