Example 1

As shown in Figure 2 and Figure 4, a hose precision measuring device mainly includes a base 6, a scale 5, a sliding deck 8, a movable knife seat 4 and a cutting knife 11, and a slide bar is fixedly installed on the base 6 3 and a fixed deck 10, the slide bar 3 is movably socketed with one end of the movable knife seat 4, and the other end of the movable knife seat 4 is a free end, and a cutting knife 11 is installed on the free end of the movable knife seat 4, and the movable knife seat 4 is free. The tool holder 4 can slide linearly relative to the slide bar 3, or the slide bar 3 can be used as a rotating shaft to rotate within a certain range relative to the slide bar 3. At least two slide grooves 9 parallel to each other are provided on the base 6, and three slide grooves 9 parallel to each other are provided in this embodiment. Corresponding to the chute 9, as shown in Figure 5, a slide rail 15 cooperating with the chute 9 is provided at the bottom of the sliding deck 8, and the sliding deck 8 moves in parallel with the fixed deck 10 and is aligned with the fixed deck. 10 to form a card slot 7.

The ruler 5 directly etched on the top surface of the seat 8 and/or the fixed holder 10 can make the structure of the precise measuring and cutting device for the hose of the present utility model simpler and more compact. The scale 5 and the card slot 7 are parallel to each other, wherein by setting the scale 5 on the sliding clamp 8 and the fixed clamp 10 at the same time, it is convenient for the operator to perform cutting operations on different sides of the base 6 .

As shown in Figure 6, when using the above-mentioned hose precise measuring and cutting device to accurately measure and cut the hose 1, the specific operation method is as follows:

First, according to the diameter of the curved hose 1 as shown in Figure 1, manually pull the sliding deck 8 away from the fixed deck 10 to a suitable position, and the sliding deck 8 and the fixed deck A slot 7 can be formed between 10, and then the hose 1 to be measured and cut is put into the slot 7. In order to adapt the slot 7 to hoses 1 of different diameters, the side surfaces of the sliding bracket 8 and the fixed bracket 10 that are in contact with the hose 1 can be respectively set as inclined surfaces, so that the slot 7 becomes a V shape. card slot.

Then, manually move the sliding bracket 8 closer to the fixed bracket 10 until the hose 1 in the slot 7 is straightened. During this process, the operator can slightly correct the hose 1 with his fingers downward, so that the hose 1 is in a relatively straight state, which is beneficial to further reduce the measurement error and cutting error of the hose 1 .

Finally, move the movable knife seat 4, and according to the scale value indicated by the scale 5, the operator can use the cutting knife 11 to measure and cut the straightened hose 1 . In order to adapt to the cutting of flexible pipes 1 with different pipe diameters, and to ensure that the flexible pipe 1 can be cut off at one time when cutting, the cutting knife 11 can be flexibly connected with the movable knife seat 4, and the cutting knife 11 can be moved relative to the The telescopic movement of the movable knife seat 4 is preferably to make the movable socket between the cutting knife 11 and the movable knife seat 4, so as to ensure that the cutting knife 11 does not deviate relative to the movable knife seat 4 when it moves telescopically, so as to ensure the cutting accuracy.

In the above-mentioned precise measurement and cutting process of the hose 1, the chute 9 is preferably a T-shaped chute, and correspondingly, the slide rail 15 is preferably a T-shaped slide rail, which can increase the relative strength of the sliding bracket 8 to the fixed The movement stability of the parallel movement of the deck 10 is conducive to improving the accuracy and reliability of the hose 1 cutting. Considering that the end of hose 1 is usually used as a measurement reference point, the flatness of the end of hose 1 has an important influence on the accurate measurement of hose 1. In order to facilitate the port cutting of the hose 1 in the card slot 7 and ensure the flatness of the hose 1 port, as shown in Figure 2 and Figure 4, it can be set at the same end of the sliding clamp 8 and the fixed clamp 10 Port cutter 2, one end of the port cutter 2 is pivotably connected to the base 6, and a cutter groove 12 can also be provided on the base 6, and the cutter groove 12 is located directly below the port cutter 2 to ensure that the port When the cutting knife 2 is pressed down, its cutting edge can completely fall into the cutting knife groove 12, so as to ensure that the end of the hose 1 can be cut off once when cutting, and ensure the flatness of the cut surface of the hose 1 end.

When the flatness of the cut surface of the hose 1 port is qualified, the flat plane on the port cutter 2 can cooperate with the cut surface of the hose 1 port and serve as the reference plane for measuring and cutting. The scale "0" on the scale 5 The position of the hose 1 is aligned with the datum plane, and at the same time, the axial movement of the hose 1 can be prevented by using the port cutter 2 . After the hose 1 is positioned in the slot 7, move the movable knife seat 4, and use the cutting knife 11 to cut the straightened hose 1 at the length to be cut according to the scale value indicated by the scale 5. Even if this knife does not necessarily cut off the hose 1, the cutting position of the hose 1 has been accurately marked, and then it is not difficult to cut off the hose 1. As shown in Fig. 4 and Fig. 5, the movable baffle 13 is articulated at one end of the sliding card seat 8, and at the same time, the limit pin 16 is fixedly connected to the sliding card seat 8, and the limit pin 16 is located below the movable baffle 13. , on the movable baffle 13, an incision groove is provided, and the movable baffle 13 and the limit pin 16 jointly form the position limiting device of the port cutter 2, wherein the movable baffle 13 can rotate at a fixed point relative to the sliding deck 8, And the movable baffle 13 can stay in a suitable fixed position through the limit pin 16 . Utilizing the limiting device of the port cutter 2, the pressed port cutter 2 can be limited in an appropriate position, so that the flat plane on the port cutter 2 and the cut surface of the hose 1 are close to each other, so as to form a hose 1, the measurement accuracy and cutting accuracy of the hose 1 can be further improved.

Example 2

As shown in Figure 3, a hose precision measuring device includes a spring 14, the spring 14 is located in the chute 9, and its two ends are respectively connected and fixed with the base 6 and the sliding holder 8, and other structures are the same as those in the embodiment 1.

When using the flexible tube precision measuring device to accurately measure and cut the flexible tube 1, its specific operation method is basically the same as that of embodiment 1. The difference is that due to the existence of the spring 14, when the sliding deck 8 is manually pulled apart and the hose 1 to be measured and cut is put into the slot 7, you only need to let go, and the sliding deck 8 can be used The contraction elastic force of the spring 14 moves closer to the fixed holder 10 until the hose 1 located in the groove 7 is straightened. Therefore, the precise measuring and cutting device for hoses in this embodiment can avoid the uneven force during the operation of purely manual straightening hose 1 in embodiment 1, ensure that the force on each part of hose 1 is basically the same, and reduce the pressure of hose 1. The difference in deformation of each part is conducive to improving the measurement accuracy and cutting accuracy of the hose 1 . At the same time, this structure also makes the structure of the precise measuring and cutting device for the hose simple and compact, the operation is more convenient, and the implementation cost is low.

The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model.
