Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a tire mold pattern module detection device. Background Art

[0002] As we all know, tire molds are key equipment used for vulcanization molding of various types of tires. They play a vital role in the tire production process. The quality of tire molds also determines the quality of the corresponding tires produced. Therefore, in order to facilitate the quality inspection of tire molds, we propose a tire mold pattern module detection device.

[0003] After searching, the Chinese patent publication number CN219511509U discloses a tire mold pattern detection device, which is roughly described as comprising a workbench, a pair of symmetrically arranged sliding blocks are slidably connected to the top of the workbench, two adjustment components are arranged on the outer sides of the pair of sliding blocks, the adjustment component comprises a fixed block fixedly connected to the top of the sliding block, the bottom of the fixed block is rotatably connected to a rotating shaft, a groove adapted to the rotating shaft is provided on the outer side of the sliding block, and a rotating rod is fixedly connected to the top of the rotating shaft. When in use, the tire mold is placed on the outer side of a pair of support plates, and a pair of electric push rods are started respectively. The pair of electric push rods drive the corresponding support plates to be close to the inner wall and limit them. According to the size of the tire mold, the screw is dragged to drive the rotating shaft to rotate through the rotating rod, and the angle of the arc plate is adjusted so that the two arc plates on one side are adapted to the outer side of the tire mold. The screw is limited by a nut, and the nut is in contact with the fixed block to keep the screw, the rotating rod and the rotating shaft stable. The double-axis motor is started, and the double-axis motor The rotation drives a pair of sliders to slide through a pair of threaded rods, and the slider drives the sliding block to slide through the corresponding connecting rod, driving the arc plate to limit the tire mold, and the electric push rod drives the detector to move through the connecting block to detect the tire mold. The Chinese patent announcement number CN213336024U discloses a tire mold pattern detection device, which is roughly described as including a bottom plate, a fixed plate is fixedly connected to the top of one side of the bottom plate, and a connecting plate is fixedly connected to the top of the other side of the bottom plate. The middle part of the connecting plate is rotatably connected with a rotating shaft, and the end of the rotating shaft close to the fixed plate is threadedly connected with a connecting cylinder, and the end of the connecting cylinder away from the rotating shaft is fixedly connected with a movable plate. When it is in use, through the cooperation between the bottom plate, the fixed plate, the movable plate, the rotating shaft and the connecting cylinder, the rotating shaft is rotated to make the connecting cylinder move along the X-axis direction, and the connecting cylinder drives the movable plate to move, so that the distance between the movable plate and the fixed plate changes, and the pressure between the two is used to fix the mold, and finally the tire mold pattern is detected by the detection head.

[0004] Although the above-mentioned prior art solutions can form corresponding detection on the tire mold, in actual situations, in order to facilitate demolding of the tire after casting and curing, most tire molds adopt multiple independent split structures. The multiple split structures are in contact with each other and closed to form a casting mold cavity of the tire, and the multiple split structures are separated from each other to facilitate demolding after the tire casting is completed. Therefore, it is not only a single split structure that determines the quality of tire casting. The overall structure of the tire mold formed by the matching installation of multiple split structures also determines the overall quality of the cast tire. Considering that the pattern in the tire mold is a plurality of repeated structural forms connected in end-to-end sequence, and although the above-mentioned two technical solutions propose to detect the formation of tire mold patterns through a detector or a detection head, the detection data is the data of a single pattern module. When a size comparison is formed for multiple pattern modules, it is necessary to repeatedly detect the data of a single pattern module and form a comparison through the detected data. The convenience of operation needs to be further improved. Summary of the invention

The ring scale plate 11 and the indicating disc 12 are fixedly connected in the adjusting frame 3 and on the rotating shaft 1 respectively. The ring scale plate 11 is provided with a scale ring 13 matching the indicating disc 12. The relative displacement between the indicating disc 12 and the ring scale plate 11 is read by the indicating disc 12 covering the scale ring 13 on the ring scale plate 11, and then the relative displacement between the fixed frame 2 and the adjusting frame 3 is read.

The step transmission frame 24 is slidably connected to the outer frame 26, and the step transmission frame 24 is provided with a flat push surface 28 matching the pressure sensor 27. The reading of the pressure sensor 27 forms the detection of the position change of the adjusting frame 3 relative to the rotating shaft 1. In order to form a detection of the position change of the adjusting frame 3 relative to the fixing frame 2, the sensitivity is higher and it is more convenient to detect the small position change between the adjusting frame 3 and the fixing frame 2.

[0025] The touch screen 30, circuit board 31, data transmission charging port 32 and button 33 in this embodiment are all conventional devices purchased on the market and known to those skilled in the art. In the present invention, we only use them without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of the instruction manual, and will not be described in detail here.

[0026] In summary, the working principle of the tire mold pattern module detection device is that before use, it is necessary to complete the relative matching installation of multiple split structures in the tire mold, that is, the multiple split structures can be matched to form a complete casting mold cavity, and then the retaining auxiliary operation structure and the adjustment auxiliary operation structure are adjusted respectively according to the specific size of the casting mold cavity relative to the retaining shift rack 5 and the adjustment shift rack 7. Under the elastic pushing action of the elastic reset spring 43, the retaining moving rack 4 and the retaining shift rack 5 are relatively moved and stopped, and then the two fixed reduced diameter circular contacts 9 are moved. The distance between the two adjusting reduced diameter round contacts 10 is slightly larger than the inner diameter of the casting mold cavity. Similarly, after the relative movement of the adjustment moving rack 6 and the adjustment opposing shifting rack 7 is stationary, the distance between the two adjusting reduced diameter round contacts 10 is slightly larger than the inner diameter of the casting mold cavity. In this state, the length of the free extension of the elastic return spring 43 will make the two auxiliary force-applying rods 46 have a suitable relative distance relative to the two auxiliary levering rods 47, respectively. The relative distance can satisfy the operator's single-handed grasping of the matching auxiliary force-applying rods 46 and auxiliary levering rods 47, and the operator can control the grasping hand The degree of closing of the palm and fingers can form the control of the relative distance between the grasped auxiliary force-applying rod 46 and the auxiliary force-assisting rod 47. By controlling the relative distance between the auxiliary force-applying rod 46 and the auxiliary force-assisting rod 47, the corresponding drive of the fixed shifting rack 5 and the corresponding drive of the adjustment moving rack 6 can be realized. Through the corresponding transmission of the two synchronous gears 8, the fixed shifting rack 5 moving relative to the fixed frame 2 can drive the fixed moving rack 4 to form a synchronous relative movement, and finally the relative distance between the two fixed reduced diameter circular contacts 9 is adjusted. The positioning movable rack 6 that moves relative to the adjusting frame 3 can drive the positioning counter-shift rack 7 to form a synchronous relative movement, and finally achieve the adjustment of the relative distance between the two positioning reduced-diameter circular contacts 10, and synchronously adjust the relative distance between the two fixed reduced-diameter circular contacts 9 and the relative distance between the two positioning reduced-diameter circular contacts 10, so that the relative distance between the two fixed reduced-diameter circular contacts 9 and the relative distance between the two positioning reduced-diameter circular contacts 10 are both smaller than the internal diameter of the casting mold cavity, so as to facilitate the overall placement of the tire mold pattern module detection device relative to the casting mold cavity.

[0027] Furthermore, both the fixed reduced-diameter circular contact 9 and the adjusted reduced-diameter circular contact 10 enter the casting mold cavity, and the relative distance between the two adjusted reduced-diameter circular contacts 10 is kept smaller than the internal diameter of the casting mold cavity, and by releasing the relative gripping action of the auxiliary lever 47 on the fixed frame 2 and the corresponding auxiliary force rod 46 on the fixed shift rack 5, under the elastic reset action of the corresponding elastic reset spring 43 between the released auxiliary force rod 46 and the auxiliary lever 47, the movement drive of the fixed shift rack 5 is formed, and under the meshing transmission action of the fixed shift rack 4, the synchronous gear 8 and the fixed shift rack 5, the moving fixed shift rack 5 will form a fixed shift rack. The synchronous driving of the movable rack 4 eventually achieves the relative distance adjustment of the two fixed reduced diameter circular contacts 9. The two relatively far-apart fixed reduced diameter circular contacts 9 will first approach the casting mold cavity and then form a tight contact with the casting mold cavity. Under the theoretical state, under the influence of the circular structure inside the casting mold cavity and the pushing effect of the corresponding elastic return spring 43, the two fixed reduced diameter circular contacts 9 will automatically coincide with the inner diameter of the casting mold cavity, and the central axis of the rotating shaft 1 coincides with the central axis of the casting mold cavity. Then, the relative distance between the adjusting frame 3 and the fixed frame 2 is adjusted according to the detection needs. The adjustment method is to rotate the threaded rod 16. Since the threaded rod 16 is rotatably connected to the fixed end block 14 Therefore, the rotation of the threaded rod 16 will not drive the fixed frame 2 to rotate, and the threaded rod 16 is threadedly connected to the rotating shaft 1. Therefore, when the operator has not yet relaxed the synchronous grasping of the auxiliary lever 47 on the adjusting frame 3 and the auxiliary force rod 46 on the adjusting and shifting rack 7, the rotation of the threaded rod 16 will drive the rotating shaft 1 to adjust the relative distance relative to the fixed frame 2, so as to achieve the synchronous adjustment of the adjusting and shifting rack 6 and the adjusting and shifting rack 7, so that the two adjusting and reducing round contacts 10 can form a corresponding relationship between different levels in the casting mold cavity. After the adjustment is completed, the operator releases the auxiliary lever 47 on the adjusting frame 3 and the auxiliary force rod on the adjusting and shifting rack 7. 46 is grasped, and under the elastic pushing action of the corresponding elastic return spring 43, the adjusting and shifting rack 7 will be relatively far away from the adjusting frame 3, and under the meshing transmission action of the adjusting and moving rack 6, the adjusting and shifting rack 7 and the synchronous gear 8, the adjusting and moving rack 6 and the adjusting and shifting rack 7 will be synchronously relatively far away, and finally the two adjusting and reducing circular contacts 10 are pressed tightly against the casting cavity. Under the theoretical state, under the influence of the circular structure inside the casting cavity and the pushing action of the corresponding elastic return spring 43, the two adjusting and reducing circular contacts 10 will autonomously coincide with the inner diameter of the casting cavity, and the central axis of the circular scale 11 coincides with the central axis of the casting cavity.

[0028] Furthermore, when the actual structure inside the casting mold cavity has a dimensional deviation compared to the circular structure under the theoretical state, it will cause the central axis of the rotating shaft 1 to deviate from the central axis of the casting mold cavity, which will eventually manifest as the central axis of the circular ring dial 11 and the central axis of the casting mold cavity to deviate from each other. Similarly, it will also cause the central axis of the indicating disk 12 to deviate from the central axis of the casting mold cavity, which is intuitively manifested as the indicating disk 12 offsetting and blocking the scale ring 13 on the circular ring dial 11. By reading the obstructed scale of the scale ring 13, it is possible to achieve a comparative detection of the relative offset between the layer contacted by the fixed reduced diameter circular contact 9 inside the casting mold cavity and the layer contacted by the adjustable reduced diameter circular contact 10. By rotating and adjusting the adjusting frame 3 relative to the fixed frame 2, a complete detection of the layer corresponding to the contact of the adjusting and reducing circular contact 10 in the casting mold cavity is realized. When the relative offset between the indicating disc 12 and the circular scale plate 11 is small, it means that the overall quality of the casting mold cavity is good. When the relative offset between the indicating disc 12 and the circular scale plate 11 is large, it means that the overall quality of the casting mold cavity is poor. During the detection process, when the relative offset between the indicating disc 12 and the circular scale plate 11 is very small and is not enough to form a reading through the relative offset change of the indicating disc 12 to the scale ring 13, the pressure sensor 27 is formed by starting the touch display screen 30. Thereafter, when a relative offset is formed between the rotating shaft 1 and the adjusting frame 3, the pressure sensor 27 is detected and intervened. When the outer ring 20 and the inner ring 21 are offset, a relative displacement will be formed between the outer ring 20 and the inner ring 21, and the movement of the inner ring 21 will drive the guide sleeve 23 and the elastic spring 25 to form a position change. Under the action of the change in the compression amount of the elastic spring 25 itself, the force acting on the step transmission frame 24 will be changed, thereby causing the corresponding pressure of the flat push surface 28 and the pressure sensor 27 to change, resulting in a change in the reading of the pressure sensor 27, so as to facilitate the improvement of the detection accuracy of the relative displacement between the indicating disk 12 and the annular dial 11. The outer ring 20 and the inner ring 21 can also be rotated to adjust the detection direction of the pressure sensor 27, so as to facilitate the adjustment of the detection preparation and the enrichment of the detection direction. The retention auxiliary operation structure is shaped relative to the retention counter-shift rack 5. When adjusting the position, the first step is to rotate the corresponding auxiliary force-applying rod 46 to make the corresponding installation connecting shaft 41 rotate relative to the fixed displacement rack 5. The rotating installation connecting shaft 41 will drive the limiting hook frame 42 fixedly connected thereto to form a separation rotation relative to the tooth marks on the fixed displacement rack 5. When the limiting hook frame 42 is completely rotated out relative to the tooth marks on the fixed displacement rack 5, the upper external slide 37 and the lower external slide 38 on the fixed displacement rack 5 can both form a displacement adjustment relative to the fixed displacement rack 5. After the adjustment is completed, the auxiliary force-applying rod 46 is rotated in the opposite direction to make the corresponding limiting hook frame 42 re-engage in the new corresponding tooth marks on the fixed displacement rack 5, so that the fixed auxiliary operation structure can be positioned relative to the fixed displacement rack 5 again.The principle of position adjustment formed by the auxiliary operation structure of the position adjustment relative to the position adjustment rack 7 is the same as the principle of position adjustment formed by the auxiliary operation structure of the position adjustment relative to the position adjustment rack 5. The position adjustment rack 5 and the position adjustment rack 6 are both provided with scale lines. Through the covering state of the fixed frame 2 and the adjustment frame 3 with the two scale lines, it is convenient to form a measurement reading of the relative distance between the two fixed reduced diameter circular contacts 9, and it is also convenient to form a measurement reading of the relative distance between the two position adjustment reduced diameter circular contacts 10.
