Description

Technical Field

[0001] This utility model relates to a tire gripper production equipment for a tire vulcanizing machine. Background Technology

[0002] Tire grippers are key equipment in the tire vulcanization process, connecting the green tire and the vulcanizing machine. Their core function is to precisely grip, transfer, and release tires during loading (transferring the green tire from the storage tank to the vulcanizing chamber) and unloading (removing the vulcanized tire from the vulcanizing chamber). For example, the tire gripper disclosed in patent number CN211968502U has a slidingly fitted movable ring and a fixed ring. The movable ring requires mounting holes for the transmission linkage, and the fixed ring requires four bolt holes for the slide rail. After casting and preliminary machining, the fixed and movable rings are as follows... Figure 1 As shown, the retaining ring at this point only has weight-reducing holes, which need to be machined into the shape shown. Figure 2 The structure shown requires ensuring the positional relationship between each hole and the positional relationship between the drilled hole and the weight reduction hole during drilling. Traditionally, this is done on a regular drilling machine, which is not only inefficient but also time-consuming and labor-intensive for positioning and adjusting the position. Utility Model Content

[0003] The purpose of this utility model is to provide a tire gripper production equipment for a tire vulcanizing machine, which can solve the technical problems of low efficiency and difficult positioning when processing mounting holes and bolt holes on fixed rings and movable rings in the traditional way.

[0004] The technical solution of this utility model is as follows: The tire vulcanizing machine tire gripper production equipment includes: frame; A positioning platform, fixed on a frame, includes a fixed plate with a circular groove. An annular positioning plate is rotatably mounted in the circular groove. The annular positioning plate has a positioning groove for positioning a movable ring and at least two positioning protrusions for inserting into a weight-reducing hole of a fixed ring to achieve positioning of the fixed ring. The shape, size, and position of the positioning protrusions correspond to the weight-reducing hole of the fixed ring. An upper set bolt is screwed into the groove wall of the positioning groove through a threaded hole to lock the movable ring. A lower set bolt is screwed into the bottom wall of the circular groove through a threaded hole to lock the annular positioning plate relative to the fixed plate. A scale line is provided at the mating point between the annular positioning plate and the fixed plate to indicate the relative rotation angle between the two. The drilling mechanism includes a left drilling module and a right drilling module, which are symmetrically arranged on the frame. The drill bit of the left drilling module is used to set the mounting holes on the movable ring, and the right drilling module includes four drill bits, which are used to set the four bolt holes on both sides of the weight reduction hole on the fixed ring.

[0005] Based on the above solution, further improvements are made as follows: rubber posts are fixed to the front ends of the upper and lower set bolts. The rubber posts increase the friction between the set bolts and the corresponding annular positioning disc and movable ring, ensuring no misalignment after positioning. They also protect the contacted outer surfaces, preventing damage from the set bolts' pressure and friction.

[0006] Based on the above solution, further improvements are made as follows: multiple evenly distributed rolling grooves are provided on the lower surface of the annular positioning disk within the circular groove, and ball bearings are rotatably assembled within the rolling grooves. This significantly reduces the friction between them.

[0007] Based on the above scheme, the following improvements are made: at least one handle is provided radially on the annular positioning disk for rotating the annular positioning disk.

[0008] Based on the above scheme, the following improvements are made: there are four positioning protrusions, which are evenly distributed along the circumference of the annular positioning disk.

[0009] Based on the above scheme, the following improvements are made: anti-slip screw sleeves are provided at the rear ends of the upper and lower set bolts.

[0010] The beneficial effects of this application are as follows: When using the tire gripper production equipment for tire vulcanizing machines, the un-drilled movable ring and fixed ring are placed on the positioning groove and positioning protrusion, respectively. The fixed ring is locked in all directions by the positioning protrusion, which corresponds to the shape, size, and position of its weight-reducing hole. The positioning groove limits the horizontal movement of the movable ring, which can only rotate relative to the annular positioning plate. Since there are no requirements for the position of the movable ring before drilling, locking is not necessary at this time. When drilling is required, the movable ring is pushed up by the upper set screw to lock it relative to the annular positioning plate. After rotating the annular positioning plate to zero the scale, the lower set screw is used to lock it. The bolt locks the annular positioning disc relative to the fixed disc. At this point, the drilling mechanism can be activated. Simultaneously, on the movable ring corresponding to the pair of weight-reducing holes, mounting holes are drilled using the left drilling module, and four bolt holes are drilled using the four drill bits of the right drilling module. After lifting the drilling mechanism, the lower set screw is loosened, and the annular positioning disc is rotated until the scale displays 45°, then stopped. The annular positioning disc is locked again using the lower set screw, and the drilling steps of the above drilling mechanism are repeated to complete the drilling of the second set of holes. Then, the step of rotating 45° each time is repeated, for a total of 7 rotations, completing the machining of a total of 40 holes on the movable and fixed rings. Therefore, this application not only precisely locks the position of the fixed ring using the positioning protrusion and marks it as the starting position, but also allows for the machining of all holes through 7 rotations and machining, making the entire process simple, convenient, fast, and efficient. Furthermore, the precise positioning ensures the machining accuracy and positional accuracy of each hole, significantly improving product quality and processing efficiency.

[0015] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0016] A specific embodiment of the tire gripper production equipment of this utility model is as follows: Figure 3-5 As shown, the tire vulcanizing machine tire gripper production equipment includes a frame 3, a positioning table 4, and a drilling mechanism.

[0017] The positioning platform 4 is fixed on the frame 3 and includes a fixed plate 41. The fixed plate 41 has a circular groove 411, and an annular positioning plate 42 is rotatably mounted in the circular groove 411. The annular positioning plate 42 has a positioning groove 421 for positioning and placing the movable ring 1, and at least two positioning protrusions 422 for inserting into the weight reduction hole 21 of the fixed ring 2 to achieve positioning of the fixed ring 2. The shape, size and position of the positioning protrusions 422 correspond to the weight reduction hole 21 of the fixed ring 2. A set bolt 423 is screwed onto the groove wall of the positioning groove 421 through a threaded hole to lock the movable ring 1. A set bolt 412 is screwed onto the bottom wall of the groove 411 through a threaded hole to lock the annular positioning disc 42 relative to the fixed disc 41. A scale line 424 is provided at the mating point between the annular positioning disc 42 and the fixed disc 41 to show the relative rotation angle between the two. The drilling mechanism includes a left drilling module 5 and a right drilling module 6. The left and right drilling modules are symmetrically arranged on the frame 3. The drill bit 7 of the left drilling module 5 is used to set the mounting hole 11 on the movable ring 1. The right drilling module 6 includes four drill bits 7, which are respectively used to set the four bolt holes 22 on both sides of the weight reduction hole 21 on the fixed ring 2.

[0018] Rubber posts 413 are fixed to the front ends of the upper set bolt 423 and the lower set bolt 412. The rubber posts 413 increase the friction between the set bolts and the corresponding annular positioning disc 42 and movable ring 1, ensuring no misalignment after positioning. They also protect the contacted outer surfaces from damage caused by the set bolts' squeezing and friction. Multiple evenly distributed rolling grooves 415 are provided within the circular groove 411 corresponding to the lower surface of the annular positioning disc 42, with ball bearings 416 rotatably mounted within each groove. This significantly reduces friction between them. At least one handle 425 is radially provided on the annular positioning disc 42 for rotating it. Four positioning protrusions 422 are evenly distributed circumferentially around the annular positioning disc 42. Anti-slip screw sleeves 414 are provided at the rear ends of the upper set bolt 423 and the lower set bolt 412.

[0019] When using the tire gripper production equipment of the tire vulcanizing machine, the un-drilled movable ring 1 and fixed ring 2 are placed on the positioning groove 421 and positioning protrusion 422, respectively. The fixed ring 2 is locked in all directions by the positioning protrusion 422, which corresponds to the shape, size and position of its weight reduction hole 21. The positioning groove 421 restricts the horizontal movement of the movable ring 1. The movable ring 1 can only rotate relative to the annular positioning plate 42. Since there is no requirement for the position of the movable ring 1 before drilling, locking is not required at this time. When drilling is required, the movable ring 1 is pushed up by the upper set bolt 423 to lock the movable ring 1 relative to the annular positioning plate 42. After rotating the annular positioning plate 42 to zero the scale, the lower set bolt 412 is used to lock the movable ring 1 relative to the annular positioning plate 42. Lock the annular positioning disk 42 relative to the fixed disk 41. At this point, the drilling mechanism can be started. Simultaneously, on the movable ring 1 corresponding to the pair of weight-reducing holes 21, drilling the mounting hole 11 through the left drilling module 5 and the four bolt holes 22 through the four drill bits 7 of the right drilling module 6. After lifting the drilling mechanism, loosen the lower set screw 412 and rotate the annular positioning disk 42 until the scale shows 45°, then stop. Lock the annular positioning disk 42 again through the lower set screw 412 and repeat the drilling steps to complete the drilling of the second set of holes. Then repeat the step of rotating 45° each time, for a total of 7 rotations, to complete the machining of a total of 40 holes on the movable ring 1 and fixed ring 2. Therefore, this application not only accurately locks the position of the fixed ring 2 using the positioning protrusion 422 and marks it as the starting position, but also allows for the machining of all holes through 7 rotations and machining, making the entire process simple, convenient, fast, and efficient. Furthermore, the precise positioning ensures the machining accuracy and positional accuracy of each hole, significantly improving product quality and processing efficiency.
