Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment detection, in particular to a binary sealing head detection fixture. Background Art

[0002] In the automated filling production of sprayers, a binary sealing mechanism is usually required to encapsulate gas and spray into an aerosol can. For example, an electric binary sealing mechanism with the patent application number "201921342911.7" includes an aerosol can contact sealing head. During use, the aerosol can contact sealing head presses on the aerosol can at its lower end, and the sealing vacuum ring starts to evacuate the air, and it is required that the aerosol can contact sealing head is always sealed to the aerosol can. For this reason, a sealing buffer air spring is specifically provided, which can play a role in buffering and providing a pre-pressure, and at the same time can, to a certain extent, make up for the problem that the aerosol can contact sealing head is not parallel to the upper end surface of the aerosol can, improving its sealing performance. However, due to the guiding mechanism provided inside the sealing buffer air spring, the adjustment and compensation range is very limited. If the parallelism deviation between the aerosol can contact sealing head and the upper end surface of the aerosol can is large, it will seriously affect the sealing effect between the aerosol can contact sealing head and the aerosol can. Therefore, it is often required that the end surface of the aerosol can contact sealing head is parallel to the tooling plate (the aerosol can is placed on the tooling plate), so as to ensure that the aerosol can contact sealing head is parallel to the upper end surface of the aerosol can.

[0003] However, for the detection of this parallelism, a feeler gauge or a single dial indicator is usually used for measurement. The operation is relatively cumbersome, the detection accuracy is low, and it is not convenient for real-time adjustment of the parallelism, bringing a lot of inconvenience to the work. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the above background art, and provide a binary sealing head detection fixture. By setting multiple groups of the dial indicator mounting parts, and fixing a dial indicator on each group of the dial indicator mounting parts, it can perform detections in multiple directions synchronously, the detection is more accurate, and it is also convenient for real-time adjustment of the parallelism, and the use is more convenient.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a binary sealing head detection fixture, including a detection base, a fixture mounting part adapted to the aerosol can contact sealing head is arranged at the upper end of the detection base, a knuckle rod and multiple dial indicator mounting parts are arranged at the lower end of the detection base, the dial indicator mounting parts are evenly arranged on the outer side of the knuckle rod, a universal bearing is arranged at the lower end of the knuckle rod, a knuckle seat is arranged outside the universal bearing, and a detection substrate is arranged outside the knuckle seat; a dial indicator is arranged on the dial indicator mounting part, and the measuring end of the dial indicator abuts against the detection substrate.

[0006] Further, a first external thread is provided at the upper end of the articulated rod, and the articulated rod is connected to the lower end of the detection base through the first external thread; a second external thread is provided at the lower end of the articulated seat, and the articulated seat is connected to the detection substrate through the second external thread.

[0007] Further, four groups of dial indicator mounting parts are provided and distributed in the four directions of east, west, south, and north. They can perform detections in multiple directions synchronously, making the detection more accurate, facilitating real-time adjustment of parallelism, and being more convenient to use.

[0008] Further, a mounting hole is provided inside the dial indicator mounting part, and a set screw threaded hole is provided on one side of the dial indicator mounting part. The lower end of the dial indicator penetrates through the mounting hole and is fixedly mounted on the dial indicator mounting part in an up-and-down adjustable manner through the set screw and the set screw threaded hole, making the installation and adjustment more convenient.

[0009] Further, a mirror surface wear-resistant layer is provided on the lower end surface of the detection substrate, which reduces the contact gap with the tooling plate and improves the detection accuracy.

[0016] The present utility model will be further described in detail below in conjunction with the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0017] As Figures 1 to 3 shown, a binary sealing head detection fixture includes a detection base 01. An installation part 03 of the fixture adapted to the aerosol can contact sealing head 02 is provided at the upper end of the detection base 01. A flexible rod 04 and four dial indicator installation parts 05 are provided at the lower end of the detection base 01. The dial indicator installation parts 05 are evenly arranged in the four directions of east, west, south, and north on the outer side of the flexible rod 04. It can perform detections in multiple directions synchronously, making the detection more accurate and facilitating real-time adjustment of the parallelism, and being more convenient to use. A universal bearing 06 is provided at the lower end of the flexible rod 04. A flexible seat 07 is provided outside the universal bearing 06. A detection substrate 08 is provided outside the flexible seat 07. A dial indicator 09 is provided on the dial indicator installation part 05. The measuring end of the dial indicator 09 abuts against the detection substrate 08.

[0018] As Figure 1 and Figure 2 shown, a first external thread 10 is provided at the upper end of the flexible rod 04. The flexible rod 04 is connected to the lower end of the detection base 01 through the first external thread 10. A second external thread 11 is provided at the lower end of the flexible seat 07. The flexible seat 07 is connected to the detection substrate 08 through the second external thread 11.

[0019] As Figure 1 and Figure 3 shown, an installation hole 12 is provided inside the dial indicator installation part 05. A set screw threaded hole 13 is provided on one side of the dial indicator installation part 05. The lower end of the dial indicator 09 penetrates through the installation hole 12 and is fixed to the dial indicator installation part 05 in an adjustable manner up and down through a set screw and the set screw threaded hole 13, making the installation and adjustment more convenient.

[0020] As Figure 1 and Figure 3 shown, a mirror wear-resistant layer 14 is provided on the lower end surface of the detection substrate 09, which reduces the contact gap with the tooling plate 15 and improves the detection accuracy.

[0021] The usage steps of the present utility model are as follows:

[0022] S1. Install the dial indicator 09 (with a measuring stroke of 10 mm) on the dial indicator mounting part 05, make the measuring end of the dial indicator 09 abut against the detection substrate 08, and press down the measuring end by 3 - 4 mm;

[0023] S2. Calibrate this detection jig (the calibration method is the prior art) to ensure that the detection substrate 08 is perpendicular to the detection base 01. At this time, adjust the pointer scale on the dial indicator 09 to make the pointers of the four groups of dial indicators 09 all point to the scale "0";

[0024] S3. Install this detection jig on the aerosol can contact sealing head 02, and then gradually lower this detection jig. At this time, the sealing buffer air spring plays a buffering role to avoid overshoot. Until the detection substrate 08 abuts against the tooling plate 15, then adjust the heights of the four directions of the tooling plate 15 according to the difference in the change amount of the four groups of dial indicators 09. This adjustment method can adopt the method of screw jacking or copper sheet support, etc., to ensure that the change amounts of the scales of the four groups of dial indicators 09 are consistent, that is, the requirement of its parallelism is met, and the detection and real-time adjustment of the parallelism are completed.
