Description

Technical Field

[0001] This utility model belongs to the field of detection device technology, specifically relating to a bottle mouth detection fixture. Background Technology

[0002] Bottle neck inspection fixtures, used to inspect the neck dimensions of preforms or bottles, determine whether the neck dimensions meet requirements. Bottle neck inspection involves measuring the outer diameter, inner diameter, and height of the neck. In existing technologies, neck inspection requires the use of a neck clamp and an inner diameter plug gauge. The clamp measures the outer diameter and height, while the plug gauge measures the inner diameter. However, the existing inspection tools have the following drawbacks:

[0003] 1. The bottle neck clamp is made as a single piece, which is not convenient for processing, affecting processing accuracy and efficiency. In addition, each bottle neck clamp can only detect one type of bottle neck. If multiple bottle necks are to be detected, multiple bottle neck clamps need to be processed accordingly, which consumes more raw materials and violates the green concept of energy conservation and material reduction.

[0004] 2. It requires holding the bottle mouth clamp to inspect the bottle mouth, and the inspection results are easily affected by human factors. Utility Model Content

[0011] As a further technical solution, the outer peripheral wall of the first insert boss is provided with a first sealing ring groove, and a first sealing ring is provided in the first sealing ring groove, and the inner wall of the first hole section is tightened by the first sealing ring.

[0012] And / or, the outer peripheral wall of the second insert boss is provided with a second sealing ring groove, and a second sealing ring is provided in the second sealing ring groove, which tightens the inner wall of the second hole section.

[0013] As a further technical solution, the detection insert is connected to the insert mounting position via a connector.

[0014] As a further technical solution, the detection insert is connected to the insert mounting position by magnetic attraction.

[0019] As a further technical solution, there are two bottle mouth inner diameter detection stations, namely a bottle mouth inner diameter detection station with the maximum allowable size and a bottle mouth inner diameter detection station with the minimum allowable size.

[0020] The two bottle neck inner diameter detection platforms are respectively connected to the top surface of the first bottle neck clamping plate;

[0021] Alternatively, two bottle neck inner diameter measuring stations can be stacked, with the largest permissible bottle neck inner diameter measuring station connected to the top surface of the first bottle neck clamping plate, and the smallest permissible bottle neck inner diameter measuring station connected to the top surface of the largest permissible bottle neck inner diameter measuring station, and the largest permissible bottle neck inner diameter measuring station and the smallest permissible bottle neck inner diameter measuring station arranged coaxially.

[0022] The beneficial effects of this utility model are as follows: By using the bottle mouth outer diameter detection hole, the bottle mouth inner diameter detection platform, and the bottle mouth height clamping position to respectively detect the outer diameter, inner diameter, and height of the bottle mouth, when detecting different styles of bottle mouths, only the corresponding detection insert, the bottle mouth inner diameter detection platform, and the second bottle mouth clamping plate need to be replaced.

Hole 21, bottle mouth inner diameter measuring platform 3, and bottle mouth height clamping position 5 correspond to the size measurement of bottle mouth outer diameter, inner diameter, and height, respectively. When measuring different styles of bottle mouths, only the corresponding measuring insert 2, bottle mouth inner diameter measuring platform 3, and second bottle mouth clamping plate 4 need to be replaced. The first bottle mouth clamping plate 1, as the base, does not need to be replaced, reducing the consumption of raw materials and conforming to the green concept of energy conservation and material reduction. Moreover, the measuring insert 2, bottle mouth inner diameter measuring platform 3, and second bottle mouth clamping plate 4 can be processed separately, which is conducive to improving processing accuracy and processing efficiency.

[0035] Specifically, the detection insert 2 can be detachably connected to the top surface of the first bottle neck plate 1, or it can be embedded and installed from the top surface of the first bottle neck plate 1.

[0036] When the detection insert 2 is inserted into the top surface of the first bottle neck clamp 1, the top surface of the first bottle neck clamp 1 has a downwardly recessed insert mounting position 11, and the detection insert 2 is detachably installed into the insert mounting position 11. The insert mounting position 11 is a stepped mounting hole, which includes a first hole segment 111 and a second hole segment 112. The first hole segment 111 extends downward from the top surface of the first bottle neck clamp 1, and the second hole segment 112 extends downward from the bottom surface of the first hole segment 111. The second hole segment 112 can extend downward to the bottom surface of the first bottle neck clamp 1, or it can extend downward to a position at a certain height from the bottom surface of the first bottle neck clamp 1. The size of the first hole segment 111 is larger than the size of the second hole segment 112, and a hole segment mounting plane 113 is formed between the first hole segment 111 and the second hole segment 112. The detection insert 2 includes a first insert boss 22 and a second insert boss 23. The first insert boss 22 is adapted to the first hole segment 111, and the second insert boss 23 is adapted to the second hole segment 112. A boss mounting plane 24 is formed between the first insert boss 22 and the second insert boss 23. In a specific implementation, the first insert boss 22 is located in the first hole segment 111, and the second insert boss 23 is located in the second hole segment 112. The boss mounting plane 24 is connected to the hole segment mounting plane 113, and the hole segment mounting plane 113 supports the boss mounting plane 24, thereby initially installing the detection insert 2 into the insert mounting position 11.

[0037] More specifically, the outer peripheral wall of the first insert boss 22 is provided with a first sealing ring groove 221, and a first sealing ring is provided in the first sealing ring groove 221; and / or, the outer peripheral wall of the second insert boss 23 is provided with a second sealing ring groove 231, and a second sealing ring is provided in the second sealing ring groove 231; by tightening the inner wall of the first hole section 111 by the first sealing ring, and / or by tightening the inner wall of the second hole section 112 by the second sealing ring, the detection insert 2 is securely installed in the insert mounting position 11.

[0038] More specifically, the detection insert 2 is connected to the insert mounting position 11 via a connector; the boss mounting plane 24 is provided with a first connecting hole 241 penetrating the first insert boss 22, and the hole section mounting plane 113 is provided with a second connecting hole 1131 extending toward the bottom surface of the first bottle neck plate 1. Based on the cooperation between the connector and the first connecting hole 241 and the second connecting hole 1131, the detection insert 2 is securely installed in the insert mounting position 11.

[0039] More specifically, the detection insert 2 is magnetically connected to the insert mounting position 11; the specific magnetic connection methods include the following two:

[0040] Magnetic attraction method 1: The mounting plane 24 of the boss and the mounting plane 113 of the hole are respectively embedded with permanent magnets of opposite polarities, and the attraction between opposite poles is achieved. The permanent magnets can be neodymium iron boron magnets, ferrite magnets, etc.

[0041] Magnetic attraction method 2: The permanent magnet is embedded in the hole section mounting plane 113, and the boss mounting plane 24 or the detection insert 2 is made of magnetically conductive material;

[0042] Alternatively, a permanent magnet may be embedded in the mounting plane 24 of the boss, and the mounting plane 113 of the hole segment or the first bottle mouth clamp 1 may be made of a magnetically conductive material; wherein the magnetically conductive material may be iron, steel, silicon steel sheet, etc.

[0043] Permanent magnets achieve adsorption and connection by generating adsorption force through magnetizing magnetically conductive materials.

[0044] Specifically, the first bottle neck clamping plate 1 has a third connecting hole 12 extending from the bottom surface to the top surface and a first pin hole 13 extending from the top surface to the bottom surface; the bottom surface of the bottle neck inner diameter measuring platform 3 has a fourth connecting hole 31 extending towards the top surface and a second pin hole 32; based on the cooperation of the positioning pin with the first pin hole 13 and the second pin hole 32, the bottle neck inner diameter measuring platform 3 is initially connected to the top surface of the first bottle neck clamping plate 1; based on the cooperation of the connector with the third connecting hole 12 and the fourth connecting hole 31, the bottle neck inner diameter measuring platform 3 is securely connected to the top surface of the first bottle neck clamping plate 1.

[0046] Specifically, the bottom surface of the first bottle neck clamping plate 1 is detachably connected to multiple support feet 6; the first bottle neck clamping plate 1 has a seventh connecting hole 15 extending from the top surface to the bottom surface; the support feet 6 have an eighth connecting hole 61 extending from the top surface to the bottom surface; based on the cooperation of the connector with the seventh connecting hole 15 and the eighth connecting hole 61, the support feet 6 are securely connected to the bottom surface of the first bottle neck clamping plate 1. By setting support feet 6 on the bottom surface of the first bottle neck clamping plate 1, it is convenient to place the testing fixture. During testing, it is only necessary to place the testing fixture on the table and test the bottle neck to be tested on the testing fixture, without having to hold the testing fixture by hand, reducing the influence of human factors on the testing results; moreover, the support feet 6 can raise the bottom surface of the first bottle neck clamping plate 1, reducing the chance of rust and extending its service life.

[0047] Specifically, there are six inspection inserts 2, which are divided into three groups along the X-axis direction. The two inspection inserts 2 within each group are arranged vertically along the Y-axis direction. The two bottle mouth outer diameter inspection holes 21 of the two inspection inserts 2 in the first group are respectively the anti-theft ring diameter inspection hole with the maximum allowable size and the anti-theft ring diameter inspection hole with the minimum allowable size; the two bottle mouth outer diameter inspection holes 21 of the two inspection inserts 2 in the second group are respectively the thread outer diameter inspection hole with the maximum allowable size and the thread outer diameter inspection hole with the minimum allowable size; the two bottle mouth outer diameter inspection holes 21 of the two inspection inserts 2 in the third group are respectively the inlet outer diameter inspection hole with the maximum allowable size and the inlet outer diameter inspection hole with the minimum allowable size. In the inspection item of the outer diameter of the bottle mouth, the outer diameter size inspections of three positions including the anti-theft ring, the thread and the inlet are included. Corresponding to this, the three positions of the bottle mouth are placed into the bottle mouth outer diameter inspection holes 21 of the three groups of inspection inserts 2. If the corresponding position of the bottle mouth can enter the corresponding bottle mouth outer diameter inspection hole 21 with the maximum allowable size and cannot enter the corresponding bottle mouth outer diameter inspection hole 21 with the minimum allowable size, then the outer diameter size of the corresponding position of the bottle mouth is qualified; if the corresponding position of the bottle mouth cannot enter the corresponding bottle mouth outer diameter inspection hole 21 with the maximum allowable size, or can enter the corresponding bottle mouth outer diameter inspection hole 21 with the minimum allowable size, then the outer diameter size of the corresponding position of the bottle mouth is unqualified.

[0048] Specifically, there are two bottle mouth inner diameter inspection platforms 3, which are arranged vertically along the Y-axis direction. The two bottle mouth inner diameter inspection platforms 3 are respectively the bottle mouth inner diameter inspection platform 3 with the maximum allowable size and the bottle mouth inner diameter inspection platform 3 with the minimum allowable size. If the bottle mouth inner diameter inspection platform 3 with the maximum allowable size cannot enter the bottle mouth, and the bottle mouth inner diameter inspection platform 3 with the minimum allowable size can enter the bottle mouth, then the inner diameter size of the bottle mouth is qualified; if the bottle mouth inner diameter inspection platform 3 with the maximum allowable size can enter the bottle mouth, or the bottle mouth inner diameter inspection platform 3 with the minimum allowable size cannot enter the bottle mouth, then the inner diameter size of the bottle mouth is unqualified. In addition, the two inner diameter inspection platforms can also be stacked along the Z-axis direction. The bottle mouth inner diameter inspection platform 3 with the maximum allowable size is connected to the top surface of the first bottle mouth clamping plate 1, and the bottle mouth inner diameter inspection platform 3 with the minimum allowable size is connected to the top surface of the bottle mouth inner diameter inspection platform 3 with the maximum allowable size. The bottle mouth inner diameter inspection platform 3 with the maximum allowable size and the bottle mouth inner diameter inspection platform 3 with the minimum allowable size are coaxially arranged. At this time, the method of inspecting the inner diameter of the bottle mouth is the same as above.

[0049] Specifically, there are four bottle neck height detection positions 5, divided into two groups along the X-axis. Within each group, two bottle neck height detection positions 5 are arranged left and right along the X-axis. The first group has two positions: one for the maximum allowable support ring height and one for the minimum allowable support ring height. The second group has two positions: one for the maximum allowable anti-theft ring height and one for the minimum allowable anti-theft ring height. The bottle neck height detection includes height checks for both the support ring and the anti-theft ring. The bottle neck is inserted into its corresponding height detection position 5. If the corresponding position of the bottle neck can fit into the maximum allowable height detection position but cannot fit into the minimum allowable height detection position, the height of that position is acceptable. If the corresponding position of the bottle neck cannot fit into the maximum allowable height detection position, or can fit into the minimum allowable height detection position, the height of that position is unacceptable.
