Description

Technical Field

[0001] The utility model belongs to the technical field of measurement, and in particular relates to a high-precision measuring tool for detecting mold dimensions. Background Art

[0002] Molds are important processing tools in tire manufacturing. Under the action of external forces, they can transform the blank into a part with a specific shape and size. However, in order to ensure the accuracy of the part, it is necessary to measure the dimensions of the mold after the tire mold is produced to determine whether the mold meets the production standards.

[0003] However, when measuring the inner diameter of a tire mold, a traditional size measuring device needs to move the measuring block to both sides. Since the measuring block of the traditional measuring device cannot effectively achieve friction damping in order to move, there may be accidental touches that cause the measuring block to move, thereby affecting the final measurement data. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of low data accuracy caused by the movement of the measuring block of the traditional measuring device due to mis-touch, and to propose a high-precision measuring tool for detecting mold dimensions.

[0007] The two ends of the spring are respectively connected to the bottom of the fixing rod and the bottom of the inner wall of the fixing groove, and the end of the support rod away from the fixing rod is connected to the bottom of the inner wall of the fixing groove. The placement groove is opened on the top of the sliding sleeve seat.

[0013] Slide grooves are provided on both sides of the inner wall of the support frame, and sliders are slidably connected in the slide grooves, and one side of the slider is connected to one side of the moving block.

[0015] The top of the base is fitted with a mold, and a through slot is opened on the top of the base, and a motor is fixedly installed on one side of the base, the output shaft of the motor extends into the through slot and is connected to a double-grooved rod, the other end of the double-grooved rod is rotatably connected to one side of the inner wall of the through slot, the outer wall of the double-grooved rod is threadedly connected to two threaded seats, the outer wall of the threaded seat is slidably connected to the inner wall of the through slot, and a plywood is connected to the top of the threaded seat, and rubber pads are provided on the opposite sides of the two plywood.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. In the present invention, a damping mechanism is provided, and the elasticity of the spring is used to cause the spring to move the fixed rod, which in turn causes the fixed rod to drive the friction plate on the top to fit into the inner wall of the measuring box, thereby generating a certain amount of friction. As a result, after the measurement is completed, friction is used to prevent accidental touch from causing the contact block to drive the sliding sleeve seat to move, thereby driving the measuring block to move and causing inaccurate measurement data, thereby ensuring the accuracy of the device's measurement.

[0018] 2. In the present invention, a motor is provided to drive the double-threaded rod to rotate, and the double-threaded rod drives the two threaded seats to move toward each other, so that the threaded seats drive the clamping plates to move, so that the two clamping plates clamp the mold.
