Description

TECHNICAL FIELD

[0001] The utility model relates to precision measurement and assembly technical field, in particular to a kind of height measuring mechanism for moulding press assembly. BACKGROUND

[0002] In moulding press assembly process, the lower hot plate of each station needs to be set in steps, and the setting range is between 0.01mm-0.15mm, to avoid the height difference of adjacent plates being too large, resulting in shaking, side turning or other quality problems when the mold is transferred. The existing measuring equipment sets a reference plate, manually presses the reference plate on the previously assembled workpiece, and then measures the height difference using measuring instruments. This measurement method is inconvenient to operate, and requires one hand to press the reference plate and the other hand to operate the measuring instrument. It is inefficient and the measurement accuracy is easily affected by human factors, making it difficult to meet the needs of high-precision assembly. UTILITY MODEL CONTENTS

[0003] The utility model aims at the defects and deficiencies of prior art, and provides a kind of height measuring mechanism for moulding press assembly.

[0004] To achieve the above object, the utility model adopts the technical scheme that:

[0005] The height measuring mechanism for moulding press assembly, comprising a base and a differential head, the bottom of the base is a flat surface, the bottom surface of the base is evenly distributed with a plurality of adsorption holes, the fixed sleeve of the differential head is fixed on the base, the orientation of the measuring rod on the differential head is consistent with the orientation of the bottom surface of the base, and the joint connected with the adsorption hole is fixed on the base.

[0006] Further, the adsorption holes are distributed in a matrix, a plurality of communication holes are provided on the base, the communication holes are connected with each other, the joint is connected in the communication hole, and the adsorption hole is connected in the communication hole.

[0007] Further, a locking device is provided on the differential head, and the locking device is used to fix the position of the measuring rod on the differential head.

[0008] Further, the locking device is a mechanical knob structure, which locks the measuring rod of the differential head through friction.

[0009] Further, the number of adsorption holes is 9.

[0010] With the above structure, the beneficial effects of this utility model are as follows: Operation is convenient; only the knob of the micrometer tumbler or micrometer head needs to be operated manually. Simply open the vacuum interface to allow the base to adhere to the reference plate, and measurement can be performed without manually pressing the reference plate, reducing manual operation steps and improving measurement efficiency. Measurement accuracy is high; the micrometer head accuracy can reach ±0.01 mm, meeting the high-precision measurement requirements of the heat spreader stepped setting under the molding machine. It has strong applicability and can be used for measuring and assembling height differences in various materials, such as tungsten steel plates, alloy plates, and ceramic plates of various materials, making it more widely applicable than a simple magnetic adsorption base.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figs. 1 to 3 As shown, the height measuring mechanism for molding machine assembly of this utility model includes a base 1 and a micrometer head 3; the bottom of the base 1 is a flat surface; a plurality of adsorption holes 103 are evenly distributed on the bottom surface of the base 1; the fixing sleeve of the micrometer head 3 is fixed on the base 1; the orientation of the measuring rod 301 on the micrometer head 3 is consistent with the orientation of the bottom surface of the base 1; a connector 2 that communicates with the adsorption holes 103 is fixed on the base 1.

[0019] The fixing sleeve of the differential head 3 is fixed on the connecting block 101 of the base 1;

[0020] The measuring rod 301 can be moved in and out after the differential cylinder is rotated; the joint 2 is connected to a negative pressure air source, the surface roughness of the bottom of the base 1 is less than 0.8 microns, the bottom surface of the base 1 is first placed on a reference plate, then the negative pressure air source is started, negative pressure is generated in the adsorption holes 103, and the base 1 is stably adsorbed on the surface of the reference plate; only the differential cylinder or the knob needs to be operated manually, the operation is convenient, the base can be adsorbed on the reference plate only by opening the vacuum interface, measurement can be performed, manual pressing of the reference plate is not needed, the artificial operation steps are reduced, and the measurement efficiency is improved; the measurement precision is high, the precision of the differential head can reach ±0.01 millimeters, high-precision measurement requirements of the step setting of the heat plate of the mold pressing machine are met; and the adaptability is high, and the height difference measurement and assembly of various different materials of plate materials, such as tungsten plates, alloy plates, and ceramic plates of various materials, can be performed, so that the base is more widely applicable than a base adsorbed by a simple magnet.

[0022] The adsorption holes 103 are evenly distributed on the bottom surface of the base 1 in matrix distribution, so that the adsorption force of the base 1 on the reference plate is more uniform. In actual processing, the main channel 102 is connected between the joint 2 and the communication hole 104; and because the communication hole 104 is laterally bored, the end port of the communication hole 104 needs to be sealed by a plug to prevent air leakage.
