Description
Technical Field
The utility model relates to a welding strength and gas tightness test fixture of plastics.
Background
From our daily life to the field of advanced science, plastic products play an increasingly important role, and are limited by the reasons of plastic processing technology and the like, and many products with complex structures cannot be processed and formed at one time, and a plurality of parts need to be seamlessly linked together through welding to form a complete part.
Currently, the most used plastic welding modes include ultrasonic welding, laser welding, hot plate welding, friction welding, high-frequency welding and the like. Different welding methods and welding processes need to be selected for plastics of different materials, so that the welding strength and the air tightness of different plastics under different welding methods need to be tested, and the existing plastic welding strength and air tightness testing tool is complex in structure, high in manufacturing cost, troublesome in operation, small in application range and to be further improved.
SUMMERY OF THE UTILITY MODEL
To the current situation of above-mentioned prior art, the utility model aims to solve the technical problem that a simple structure is provided, low in manufacturing cost is honest and clean, easy operation is convenient, the welding strength and the gas tightness test frock of plastics that application scope is wide is provided.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a welding strength and gas tightness test fixture of plastics, its characterized in that, includes casing, lid and pneumatic joint, lid seal weld is in the upper end opening part outside edge of casing, the recess that the hoop distributes is seted up at the lower plane edge of lid, the upper end opening part of casing inserts in the recess, the inside bottom surface center of casing upwards is formed with the support column, the upper end laminating of support column is on the lower plane of lid, the bottom at the casing is established to pneumatic joint detachable sealed the inlaying.
Preferably, a threaded hole is formed in one side of the inner bottom surface of the shell, and the pneumatic connector is inserted into the threaded hole in a sealing and threaded mode.
Compared with the prior art, the utility model has the advantages of: the utility model discloses simple structure, low in manufacturing cost is honest and clean, and easy operation is convenient, and application scope is wide.

Detailed Description
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.
As shown in fig. 1, a plastic welding strength and air tightness testing tool comprises a shell 1, a cover body 2 and a pneumatic connector 3, wherein the cover body 2 is welded on the outer edge of an opening at the upper end of the shell 1 in a sealing manner, the lower plane edge of the cover body 2 is provided with grooves 21 which are distributed annularly, the opening at the upper end of the shell 1 is inserted into the groove 21, a support column 11 is formed upwards in the center of the inner bottom surface of the shell 1, the upper end of the support column 11 is attached to the lower plane of the cover body 2, and the pneumatic connector 3 is detachably embedded at the bottom of the shell 1 in; one side of the inner bottom surface of the shell 1 is provided with a threaded hole 12, and the pneumatic connector 3 is inserted into the threaded hole 12 in a sealing mode.
When in use: the clamp 4 is opened to enable two ends of the clamp 4 to be clamped at the centers of the outer sides of the shell 1 and the cover body 2 respectively and located at the outer sides of two ends of the supporting columns 11 respectively, so that the shell 1 and the cover body 2 are temporarily fixed, then the shell 1 and the cover body 2 are hermetically welded at the outer side joint of the shell 1 and the cover body 2 by using one of welding modes, and the supporting columns 11 are arranged to prevent the cover body 2 from sinking due to the clamping force of the clamp 4, so that the edge of the cover body 2 is uneven, and the welding quality is guaranteed; then, the pressurizing equipment is connected with the pneumatic connector 3 through an air pipe, then, the pressurizing equipment introduces high-pressure air between the shell 1 and the cover body 2 through the air pipe and the pneumatic connector 3, the pressure between the shell 1 and the cover body 2 is gradually increased along with the continuous introduction of the high-pressure air, finally, the explosion occurs, and the air pressure intensity during the explosion is recorded; in a similar way, the shell 1 and the cover body 2 are subjected to sealing welding in another welding mode and are subjected to inflation blasting again, the air pressure intensity during blasting is recorded after blasting, and the size of the air pressure intensity during two blasting processes is compared, so that the welding mode which is more suitable for the materials of the shell 1 and the cover body 2 can be obtained.
The utility model discloses simple structure, low in manufacturing cost is honest and clean, and easy operation is convenient, and application scope is wide.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
