The inability of fixtures to automatically adjust these parameters results in instability of the tire blanks during processing, increasing the risk of product defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing tire blank clamps in the prior art, which are difficult to automatically clamp various types of tire blanks.

[0006] To solve the above technical problems, this utility model provides a multi-station automatic tire blank positioning fixture, comprising: a base, an operating table fixedly connected to the upper surface of the base, two tire blank bodies placed on the upper surface of the operating table, a clamping structure provided on the upper surface of the operating table, the clamping structure including a connecting plate, the connecting plate being fixedly connected to the operating table, connecting rods fixedly connected to both ends of the connecting plate near the tire blank bodies, positioning plates fixedly connected to the ends of the two connecting rods that are close to each other, four positioning seats fixedly connected to the side of the base near the connecting plate, a motor fixedly connected to the end of the four positioning seats away from the base, a chain drivingly connected to the output end of the motor, a sprocket drivingly connected to the end of the chain near the connecting plate, a screw fixedly connected inside the sprocket, two moving rings threadedly connected to the arc surface of the screw, opposite threads opened at both ends of the screw, adjusting rods fixedly connected to the side of the two moving rings near the connecting plate, clamping plates fixedly connected to the ends of the two adjusting rods that are far from each other, and the inner wall of the connecting plate being slidably connected to the two adjusting rods.

[0007] The effect achieved by the above components is as follows: when it is necessary to clamp the tire blank body, the motor output end drives the chain, the chain drives the sprocket to rotate, and at the same time the sprocket drives the screw to rotate. The screw drives the moving ring to move away from each other, and at the same time the moving ring drives the adjusting rod to move closer to the tire blank body. The adjusting rod drives the clamping plate to move towards the positioning plate. The clamping plate and the positioning plate clamp the tire blank body at the same time, thereby achieving the effect of automatic positioning of the tire blank.

[0008] Preferably, the inner walls of both the positioning plate and the clamping plate are fixedly connected with buffer pads, and the cross-section of the buffer pads is arc-shaped.

[0009] The effect achieved by the above components is that when the positioning plate and clamping plate hold the tire blank body, they can buffer the pressure on the surface of the tire blank body, thereby achieving the effect of protecting the tire blank body.

[0010] Preferably, two limiting blocks are fixedly connected to both ends of the connecting plate near the screw, and the inner wall of the limiting blocks is rotatably connected to the screw.

[0011] The effect achieved by the above components is to prevent the screw from deviating in other directions when the motor drives the screw to rotate, so that the screw rotates more stably on the inner wall of the limit block.

[0012] Preferably, a limiting rod is fixedly connected to the inner wall of the connecting plate, and the adjusting rod is slidably connected to the limiting rod.

[0013] The effect achieved by the above components is that when the adjusting rod moves, it can move on the arc surface of the limiting rod, thereby achieving the function of limiting the adjusting rod.

[0014] Preferably, the upper surface of the connecting plate is provided with a heating structure, the heating structure including a back plate, the back plate being fixedly connected to the upper surface of the connecting plate, a slide rail being fixedly connected to the upper surface of the back plate, a slider being slidably connected to the inner wall of the slide rail, a lead screw being threadedly connected to the inside of the slider, the lead screw abutting against the slide rail, a knob being fixedly connected to the upper surface of the lead screw, a connecting rod being fixedly connected to the upper surface of the slider, an adjusting plate being fixedly connected to the end of the connecting rod away from the slider, a rotating shaft being rotatably connected to the inside of the adjusting plate, and a disc being rotatably connected to the arc surfaces at both ends of the rotating shaft, a plurality of insertion holes being opened on the inner walls of the discs and the adjusting plate, pins being slidably connected to the inner walls of the insertion holes, a connecting plate being fixedly connected to the lower surface of the disc, a round rod being fixedly connected to the end of the connecting plate away from the disc, a fixing frame being fixedly connected to the lower end of the round rod, and heating lamps being fixedly connected to both sides of the inner wall of the fixing frame.

When the connecting rod moves, it moves the adjusting plate and the disc in the direction that needs to be heated. The disc moves the connecting plate and the round rod, and the round rod moves the heating lamp inside the fixing frame. When it moves to the appropriate position, rotating the knob on the upper surface of the slider moves the lead screw downward. Then, the adjusting plate and the rotating shaft inside the disc are rotated. When the appropriate position is reached, the insertion hole is aligned and the pin is inserted, thereby adjusting the heating range of the heating lamp.

[0019] The effect achieved by the above components is that the anti-slip pad moves downward so that it makes full contact with the slide rail, increasing the friction and thus fixing the slider.

[0020] Compared with related technologies, the multi-station automatic tire blank positioning fixture provided by this utility model has the following beneficial effects:

[0021] By setting up a clamping structure, when it is necessary to fix the tire blank body, the motor drives the chain to rotate, the chain drives the sprocket to rotate, the sprocket drives the screw to rotate in the limiting block, the screw rotation drives the moving ring to move away from each other in the arc surface of the screw, the moving ring drives the adjusting rod to move away from each other in the arc surface of the limiting rod, the adjusting rod drives the clamping plate to move towards the positioning plate, and the clamping plate drives the inner wall buffer pad to move towards the positioning plate, thus achieving the function of automatically clamping the tire blank.

[0022] By setting up a heating structure, when it is necessary to heat the damaged part of the tire blank for repair, first move the slider. When it is moved to the appropriate position, rotate the knob. The knob drives the lead screw to move downward. The lead screw drives the anti-slip pad to press downward, increasing the friction with the slide rail, thus achieving the effect of fixing the slider. When it is necessary to adjust the angle of the heating lamp, first pull out the pin from the socket, rotate the disc, and when the appropriate angle is reached, align the pin with the socket and insert it into the socket, thereby achieving the effect of adjusting the angle of the heating lamp.

The inner wall of the connecting plate 401 is slidably connected to the two adjusting rods 411. When it is necessary to clamp the tire blank body 3, the output end of the motor 406 drives the chain 407 to rotate. The chain 407 drives the sprocket 408 to rotate. At the same time, the sprocket 408 drives the screw 409 to rotate. The screw 409 drives the moving ring 410 to move away from each other. At the same time, the moving ring 410 drives the adjusting rod 411 to move closer to the tire blank body 3.

Heating lamps 512 are fixedly connected to both sides of the inner wall of the fixing bracket 511. When heating is required at the location of the tire blank body 3 after repair, the slider 503 is pulled to move the connecting rod 504. When the connecting rod 504 moves, it can move the adjusting plate 505 and the disc 507 in the direction that needs to be heated. The disc 507 moves the connecting plate 509 and the round rod 510. The round rod 510 moves the heating lamp 512 inside the fixing frame 511. When it moves to the appropriate position, the knob 516 on the upper surface of the slider 503 is rotated to move the lead screw 514 downward. Then the rotating shaft 506 inside the adjusting plate 505 and the disc 507 is adjusted to rotate. When it is adjusted to the appropriate position, the insertion hole 508 is aligned and the pin 513 is inserted, so that the heating range of the heating lamp 512 can be adjusted.

[0035] When heating is needed to repair the damaged area of ​​the tire blank body 3, first move the slider 503. When it is moved to the appropriate position, rotate the knob 516. The knob 516 drives the lead screw 514 to move downward. The lead screw 514 drives the anti-slip pad 515 to press downward, increasing the friction with the slide rail 502, thus achieving the effect of fixing the slider 503.
