Description

Technical Field

[0001] The utility model relates to the technical field of assembly gap detection, in particular to an assembly gap detection tool for a mandrel and push rod connector. Background Art

[0002] After the plug is connected to the ejector rod, the perforation begins. The assembly gap between the connector and the plug is mainly measured with a vernier caliper. Since the assembly surface of the connector and the plug is a tapered surface, it is not easy to measure with a vernier caliper. If the assembly gap between the connector and the plug is too small, it will cause the plug to be unable to be assembled. If the gap is too large, it will cause the plug to sag and shake during the perforation process, increasing the extreme difference in the wall thickness of the rough tube, affecting the product quality. In severe cases, it will cause the plug to fall off. When rolling without a plug, it will cause a serious perforation and rolling accident.

[0003] The thickness gauge is made of thin steel sheets and consists of several pieces of different thicknesses. It is mainly used to check the gap between two joint surfaces, so it is also called a "feeler gauge" or "seam gauge". The thickness of each piece of gauge is marked in millimeters.

[0004] The prior art has multiple feeler gauges with different thicknesses. When measuring, the gauges need to be inserted and pulled out of the gaps continuously until a suitable gauge is found, which makes the measurement cumbersome. In addition, multiple gauges take up a large space when stored, and adjacent gauges are prone to mutual interference during measurement. Therefore, a tool for detecting the gap between the head and the push rod connector assembly is needed. Utility Model Content

[0005] The purpose of the present application is to provide a tool for detecting the assembly gap of a mandrel and mandrel connector to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a tool for detecting the gap between a mandrel and a mandrel connector assembly, comprising a scale piece group, the scale piece group comprising a head scale piece, a middle scale piece and a tail scale piece which are slidably connected in sequence, the head scale piece is the thinnest, a plurality of middle scale pieces are provided, and the thicknesses of the head scale piece, the plurality of middle scale pieces and the tail scale piece increase in sequence;

[0007] The intermediate scale piece and the tail scale block are both provided with receiving grooves. The receiving groove provided on the intermediate scale piece is used to receive the previous intermediate scale piece or the head scale piece close to the head scale piece, and the receiving groove provided on the tail scale block is used to receive the intermediate scale piece. The head scale piece, several intermediate scale pieces and the tail scale block are slidably connected in sequence.

[0008] A support rod is fixed on one end of the head scale piece close to the tail scale block, and an end of the support rod away from the head scale piece slides through a plurality of intermediate scale pieces and the tail scale block and is connected with an operating handle.

[0009] Preferably, the support rod is composed of a plurality of detachable support blocks, and the plurality of detachable support blocks are fixedly connected by connecting bolts.

[0010] Preferably, a convex head and a concave groove are formed at the front and rear ends of the support block respectively, and the convex head and the concave groove are adapted to each other. The front end of one of the support blocks is fixed to the end of the head scale piece close to the operating handle, and one end of the other support block is fixed to the end of the operating handle close to the head scale piece. Several support blocks are also installed between one support block and the other support block, and a connecting bolt passes through the connection between the concave groove and the convex head from one side.

[0015] 1. In the utility model, through the arrangement of the scale piece group and the support rod, when it is necessary to detect the gap after the assembly of the top head and the top rod connector, it is only necessary to hold the operating handle and push the support rod to make the support rod move and push the head scale piece, and the head scale piece enters the gap, and then several intermediate scale pieces on the rear side of the head scale piece are unfolded and enter the gap in turn, until a certain intermediate scale piece or the tail scale piece is blocked and cannot enter the gap. At this time, the last intermediate scale piece entering the gap is the thickness of the gap. The gap detection tool for the top head and the top rod connector assembly can be used to quickly detect the gap after the top head and the connector are assembled. The gap between the multiple scale pieces is determined by the size of the scale pieces.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-3 The tool for detecting the gap between the mandrel and the mandrel connector assembly shown in the figure comprises a blade assembly 1, wherein the blade assembly 1 comprises a head blade 11, a middle blade 12 and a tail blade block 13 which are slidably connected in sequence, wherein the head blade 11 is the thinnest, and a plurality of middle blades 12 are provided, and the thicknesses of the head blade 11, the plurality of middle blades 12 and the tail blade block 13 are increased in sequence;

[0024] The intermediate scale piece 12 and the tail scale block 13 are both provided with a receiving groove 14. The receiving groove 14 provided on the intermediate scale piece 12 is used to receive the previous intermediate scale piece 12 or the head scale piece 11 close to the side of the head scale piece 11, and the receiving groove 14 provided on the tail scale block 13 is used to receive the intermediate scale piece 12. The head scale piece 11, the plurality of intermediate scale pieces 12 and the tail scale block 13 are slidably connected in sequence.

[0025] A support rod is fixed to one end of the head scale piece 11 close to the tail scale block 13, and the end of the support rod away from the head scale piece 11 slides through several intermediate scale pieces 12 and the tail scale block 13 and is connected to the operating handle 2. At the same time, support holes 15 for the support rod to pass through are also opened on the intermediate scale pieces 12 and the tail scale block 13.

[0026] Based on the above structure, when it is necessary to detect the gap after the assembly of the top and push rod connector, it is only necessary to hold the operating handle 2 and push the support rod to move the support rod and push the head scale piece 11, so that the head scale piece 11 enters the gap, and then several intermediate scale pieces 12 on the rear side of the head scale piece 11 are unfolded and enter the gap in turn, until a certain intermediate scale piece 12 or the tail scale piece 13 is blocked and cannot enter the gap. At this time, the last intermediate scale piece 12 that enters the gap (or the head scale piece 11, that is, after the head scale piece 11 enters the gap, the subsequent intermediate scale pieces 12 are blocked and cannot enter the gap) is the thickness of the gap. The gap detection tool for the top and push rod connector assembly can be used to detect the gap between the top and push rod connector. The gap after the rear-mounted top head and the connector are quickly assembled. Since multiple scale pieces are unfolded in sequence, there will be no interference between the scale pieces, and the measurement is convenient. After the measurement, only the operating handle 2 needs to be pulled to make the operating handle 2 drive the head scale piece 11 to move toward the tail tooth block through the support rod, and drive the several middle scale pieces 12 to move during the movement, so that the several middle scale pieces 12 and the head scale piece 11 are stored in sequence, so that the space occupied by the multiple scale pieces after storage is small, thereby achieving the purpose of facilitating storage and reducing the occupied space after storage, and also making the top head and top rod connector assembly gap detection tool more convenient to carry and use.

[0027] Furthermore, the support rod is composed of a plurality of detachable support blocks 3, and the plurality of detachable support blocks 3 are fixedly connected by connecting bolts 4, and a convex head 31 and a concave groove 32 are formed at the front and rear ends of the support blocks 3, respectively, and the convex head 31 and the concave groove 32 are adapted to each other, and the front end of one of the support blocks 3 is fixed to the end of the head scale piece 11 close to the operating handle 2, and one end of the other support block 3 is fixed to the end of the operating handle 2 close to the head scale piece 11, and a plurality of support blocks 3 are installed between one support block 3 and another support block 3, and the connecting bolt 4 passes through the connection between the concave groove 32 and the convex head 31 from one side;

[0028] The connecting bolt 4 is a square rod structure, and the protrusion 31 and the recess 32 are both provided with square holes adapted to the connecting bolt 4;

[0029] By configuring the support rod to be a plurality of detachable support blocks 3, when the ruler set 1 is folded, the user can separate the plurality of support blocks 3 connected end to end by pulling out the connecting bolt 4, thereby disassembling and storing the plurality of support blocks 3, thereby further avoiding the phenomenon that the support rod is large in size after storage, resulting in a large space occupation. At the same time, it is also convenient for the user to flexibly change the length of the support rod according to actual use needs, thereby unfolding different numbers of rulers when measuring the gap thickness, which is more flexible and convenient to use.

[0030] Furthermore, a storage groove 21 is opened at the upper end of the operating handle 2, and several support blocks 3 and several connecting bolts 4 are placed in the storage groove 21 after being disassembled. A box cover 22 for closing the storage groove 21 is hinged at the opening of the storage groove 21. Through the setting of the storage groove 21, multiple support blocks 3 and multiple connecting bolts 4 that have been disassembled can be stored, which can further avoid the loss of the support blocks 3 or connecting bolts 4 after disassembly, and is also convenient for orderly storage of the support blocks 3 and connecting bolts 4 after disassembly, and the actual use effect is better.

[0031] Furthermore, a compensating gasket 5 is fixed to the rear side of the tail scale block 13. When the head scale piece 11, several intermediate scale pieces 12 and the tail scale block 13 are fully extended, the side wall of the operating handle 2 close to the tail scale block 13 abuts against one side of the compensating gasket 5. The use of the compensating gasket 5 can avoid the occurrence of a gap between the operating handle 2 and the tail scale block 13 after the head scale piece 11, several intermediate scale pieces 12 and the tail scale block 13 are fully extended, thereby ensuring the stability of the overall structure of the top and top rod connector assembly gap detection tool, thereby facilitating the use of the top and top rod connector assembly gap detection tool for stable measurement operations.

[0032] Working principle of the utility model: in daily use, when it is necessary to detect the gap after the assembly of the top head and the top rod connector, you only need to hold the operating handle 2 and push the support rod to move the support rod and push the head scale piece 11, and the head scale piece enters the gap. Then, several intermediate scale pieces 12 on the rear side of the head scale piece 11 are unfolded and enter the gap in turn, until a certain intermediate scale piece 12 or the tail scale block 13 is blocked and cannot enter the gap. At this time, the last intermediate scale piece 12 or head scale piece 11 to enter the gap is the thickness of the gap. Using this top and top rod connector assembly gap detection tool can quickly adjust the gap after the top head and the connector are assembled. Since multiple scale pieces are unfolded in turn, there will be no mutual interference between the scale pieces, and the measurement is convenient. After measurement, you only need to pull the operating handle 2 to make the operating handle 2 drive the head scale piece 11 to the tail through the support rod. The tooth block moves, and during the movement, it drives several middle scale pieces 12 to move, so that several middle scale pieces 12 and the head scale piece 11 are stored in sequence, so that the space occupied by multiple scale pieces after storage is small. At the same time, by setting the support rod as multiple detachable support blocks 3, when the scale piece group 1 is stored, the user can separate the multiple support blocks 3 connected end to end by pulling out the connecting bolt 4, so as to disassemble and store the multiple support blocks 3, thereby further avoiding the phenomenon that the support rod has a large volume after storage, resulting in a large space occupation, thereby achieving the purpose of facilitating storage and reducing the occupied space after storage, and also making the head and top rod connector assembly gap detection tool more convenient to carry and use, and also convenient for the user to flexibly change the length of the support rod according to actual use needs, so as to unfold different numbers of scale pieces when measuring the gap thickness, which is more flexible and convenient to use.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
