Description

Technical Field

[0001] The utility model relates to the technical field of tire mold processing, in particular to an S-shaped mold splitting fixture for tire pattern processing. Background Art

[0002] In tire mold processing, the shape, size and arrangement of the tread blocks directly determine the pattern style on the tire surface. Different pattern designs can give the tire different appearances. The shape, arrangement and vibration characteristics of the tread blocks when in contact with the ground will affect the noise level of the tire. Reasonable design of the tread blocks can change the way air flows between the tire patterns, reduce air vibration, and thus reduce the noise generated during the tire rolling process.

[0003] The shape of the tread block is usually quite special, with arc-shaped and irregular shapes. Some existing clamp designs do not fit the shape of the tread block well enough and cannot completely fit the surface of the tread block, resulting in a small contact area during clamping and an inability to provide uniform clamping force. This can easily cause the tread block to loosen and shake during processing, affecting the engraving accuracy. In view of this, an S-type parting clamp for tire pattern processing is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide an S-shaped parting fixture for tire pattern processing, so as to solve the problem that the fixture proposed in the related art cannot completely fit the surface of the pattern block, resulting in looseness and shaking during the processing, which affects the engraving accuracy.

[0006] Furthermore, the positioning mechanism includes a reference hole opened on the top of the fixed plate, there is a height difference between the connecting plate and the fixed plate, and a reference groove is formed, the top of the connecting plate is fixedly connected with a positioning pin, and the side walls of the fixed plate and the mounting plate are penetrated by fixing holes, and the internal threads of the fixing holes are connected with bolts.

[0007] Furthermore, the adjustment assembly includes forward and reverse screw rods rotatably installed inside the mounting plate, and the forward and reverse screw rods are fixedly connected to a handle at one end away from the mounting plate.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] See also Figures 1-4 As shown, the purpose of this embodiment is to provide an S-type parting fixture for tire pattern processing, including a mounting plate 1, a fixing plate 5 is fixedly connected to the top of the mounting plate 1, and connecting plates 4 are fixedly connected to both sides of the fixing plate 5, and the bottom of the connecting plate 4 is fixedly connected to the top of the mounting plate 1, and the connecting plate 4 and the side wall of the fixing plate 5 form an S-shaped avoidance groove 9. A positioning mechanism for positioning the pattern block is provided in the fixing plate 5, and the positioning mechanism includes a reference hole 8 opened at the top of the fixing plate 5, and there is a height difference between the connecting plate 4 and the fixing plate 5, and a reference groove 18 is formed. The top of the connecting plate 4 The top of the mounting plate 1 is fixedly connected with a positioning pin 7, and the side walls of the fixing plate 5 and the mounting plate 1 are penetrated with a fixing hole 12, and the internal thread of the fixing hole 12 is connected with a bolt 6. Clamps 3 are slidably installed on both sides of the top of the mounting plate 1, and an adjustment component for adjusting the position of the clamping plate 3 is provided in the mounting plate 1. Fixing grooves 10 are penetrated on both sides of the mounting plate 1, and the inside of the fixing groove 10 is fixedly connected with the base 2. The top shapes of the clamping plate 3, the connecting plate 4 and the fixing plate 5 are all arc-shaped. The arc shape is designed to fit completely with the surface of the pattern block to prevent loosening or shaking during processing;

[0022] The S-shaped avoidance groove 9 is to prevent the fixture from being cut when processing the S-shaped parting surface of the pattern block. First, the fixture is fixed on the processing table through the base 2 and the fixing groove 10, and then the pattern block can be quickly and accurately positioned using the reference groove 18, the reference hole 8 and the positioning pin 7. At this time, the arc surface of the fixing plate 5 is completely in contact with the pattern block, and then two bolts 6 are passed through the fixing holes 12 and screwed into the corresponding threaded holes of the pattern block for preliminary fixation. Finally, the two splints 3 further fix the pattern block to prevent the pattern block from loosening or shaking during processing, which affects the engraving accuracy.

[0023] The adjustment assembly includes a forward and reverse screw rod 13 rotatably mounted inside the mounting plate 1, and a handle 11 is fixedly connected to one end of the forward and reverse screw rod 13 away from the mounting plate 1. Two left-right symmetrical screw nuts 16 are threadedly mounted on the forward and reverse screw rod 13, and the top of the screw nut 16 is fixedly connected to the bottom of the clamping plate 3. Two slide grooves 14 are provided inside the mounting plate 1, and the outer wall of the screw nut 16 is slidably mounted inside the slide groove 14. Two limiting grooves 15 communicating with the slide groove 14 are provided inside the mounting plate 1, and a limiting block 17 is slidably installed in the limiting groove 15, and the side wall of the limiting block 17 is fixedly connected to the side wall of the screw nut 16;

[0024] The forward and reverse screw rods 13 are provided with two sections of threads in opposite directions, and the rotation direction of the two sections of threads is symmetrically arranged with the midpoint of the forward and reverse screw rods 13 as the center. The screw nut 16 is symmetrically arranged with the midpoint of the forward and reverse screw rods 13 as the center. When the forward and reverse screw rods 13 rotate, the screw nut 16 will also rotate. Under the action of the limit block 17 and the limit groove 15, it can be ensured that the screw nut 16 only moves horizontally in the slide groove 14. By turning the handle 11 to drive the forward and reverse screw rods 13 to rotate, the two screw nuts 16 move close to or far away from each other, and at the same time drive the two splints 3 to move close to or far away from each other, so as to adjust the spacing of the clamp to adapt to pattern blocks of different sizes. Finally, by turning the handle 11, the two splints 3 are further fixed to the pattern blocks.

[0025] During specific use of the present invention, the fixture is fixed on the processing table through the base 2 and the fixing groove 10, and the reference groove 18, the reference hole 8 and the positioning pin 7 can be used to quickly and accurately position the pattern block. At this time, the arc surface of the fixing plate 5 is completely in contact with the surface of the pattern block, and then the two bolts 6 are passed through the fixing holes 12 and screwed into the corresponding threaded holes of the pattern block for preliminary fixation. Finally, the two splints 3 further fix the pattern block to prevent the pattern block from loosening or shaking during the processing, which affects the engraving accuracy. When the sizes of the pattern blocks are inconsistent, the forward and reverse screw rods 13 are rotated by rotating the handle 11, so that the two screw nuts 16 move closer or farther away, and at the same time drive the two splints 3 to move closer or farther away. The spacing between the two splints 3 can be adjusted to adapt to pattern blocks of different sizes. Finally, the two splints 3 are further fixed to the pattern blocks by rotating the handle 11.
