DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0034] Example 1: Reference Figure 1-Figure 7A cutting device with a detection function for spring processing includes a mounting table 1, and also includes: a mounting frame 2, the mounting frame 2 is mounted on the mounting table 1, an upper cutter 25 and a lower cutter 26 are arranged on the mounting frame 2, the upper cutter 25 makes a reciprocating up and down motion toward the lower cutter 26 to cut the spring; a feeding cylinder 16 arranged on the mounting table 1 is rotated to automatically transport the spring between the upper cutter 25 and the lower cutter 26; a turntable 3 connected to the mounting table 1 is rotated, a plurality of material receiving seats 33 are arranged on the circumference of the turntable 3, and a material receiving groove 34 is opened in the material receiving seat 33, so that before the upper cutter 25 and the lower cutter 26 cut the spring, The cut section of the spring is located in the receiving groove 34 of the receiving seat 33; after the spring is cut, it falls into the receiving groove 34 of the receiving seat 33, and a pressure sensor 322 corresponding to the receiving seat 33 is arranged on the turntable 3, which is used to detect the elastic force of the spring after the spring in the receiving seat 33 is compressed; a mounting plate 11 is installed on the mounting table 1, and the feeding cylinder 16 is rotatably connected to the mounting plate 11 near one end of the mounting frame 2, and a motor 162 is installed on the mounting plate 11, and gears 161 are installed on the output end of the motor 162 and one end of the feeding cylinder 16, and the two gears 161 are meshed; a first guide plate 5 and a second guide plate 6 are respectively installed on the mounting table 1;

[0035] The device can automatically convey the spring located on the mounting plate 11 between the upper cutter 25 and the lower cutter 26 through the intermittent rotation of the feeding cylinder 16, and the upper cutter 25 moves downward to cooperate with the cutting edge of the lower cutter 26 to cut the spring, and the cut spring located in the receiving seat 33 is transposed by the rotation of the turntable 3. During the transposition process, the spring in the receiving seat 33 is driven to be squeezed, and the elastic force of the compressed spring is measured by the pressure sensor 322, and then the elastic force performance of the cut spring is tested to avoid the cut spring elastic force not meeting the requirements;

[0036] Specifically, when the device is in use, the spring to be cut is placed on the mounting plate 11 (it should be noted that the spring to be cut is longer, not shorter), and the feeding cylinder 16 intermittently feeds between the lower cutter 26 and the upper cutter 25, thereby realizing automatic feeding of the spring;

[0037] Subsequently, the upper cutter 25 is moved downward to cut the spring, and when the feeding cylinder 16 feeds the spring between the upper cutter 25 and the lower cutter 26, the receiving seat 33 on the turntable 3 will be located on one side of the upper cutter 25 and the lower cutter 26, and the spring fed between the upper cutter 25 and the lower cutter 26 by the feeding cylinder 16, that is, the extended part, will be located in the receiving groove 34 of the receiving seat 33. After the upper cutter 25 cuts the spring, the cut spring will remain in the receiving groove 34, and during the rotation and transposition process of the turntable 3, the spring in the receiving seat 33 is driven to be squeezed, and the elastic force of the compressed spring is detected by the pressure sensor 322, and then the elastic force performance of the cut spring is tested to avoid the cut spring elastic force not meeting the requirements.

[0038] The qualified springs will fall into the first guide plate 5, and the unqualified springs will fall into the second guide plate 6 for easy collection.

[0039] Example 2: Reference Figure 2 , Figure 3 , Figure 4 , a cutting device with detection function for spring processing, which is basically the same as the embodiment 1, and further comprises: two guide rods 12 connected by a connecting block 13, an adjusting frame 14 is symmetrically fixedly connected to the mounting plate 11, and an adjusting slot 15 is provided on the adjusting frame 14, and the connecting blocks 13 at both ends of the guide rod 12 are respectively slidably connected to the corresponding adjusting slots 15 to adjust the position of the guide rod 12 on the mounting plate 11;

[0040] The spring to be cut is located between two guide rods 12. The guide rods 12 are made of metal and have a certain weight. Therefore, after adjusting the position on the adjustment frame 14, the guide rods 12 will not slide at will. Therefore, the spring can be limited during the feeding process of the feeding tube 16 to prevent the spring from skewing.

[0041] Example 3: Reference Figure 1 , Figure 2 , Figure 5 , a cutting device with detection function for spring processing, which is basically the same as the embodiment 2, and further: the mounting frame 2 is symmetrically connected with guide columns 22, a connecting rod 23 is slidably connected between the two guide columns 22, a tool holder 24 is installed on the connecting rod 23, an upper cutter 25 is installed on the tool holder 24 by bolts, and a lower cutter 26 is installed on the lower bottom plate of the mounting frame 2, and a main cylinder 21 is installed on the mounting frame 2, and the telescopic end of the main cylinder 21 is connected to the connecting rod 23;

[0042] A plurality of first cylinders 31 are fixedly connected to the circumference of the turntable 3, and a material receiving seat 33 is connected to the telescopic end of the first cylinder 31 to push the material receiving seat 33 to approach the upper cutter 25 and the lower cutter 26;

[0043] The main cylinder 21 pushes the connecting rod 23, so that the upper cutter 25 moves down to approach the lower cutter 26, thereby cutting the spring. The main cylinder 21 is used to drive the upper cutter 25 to reciprocate up and down, which is very convenient and has a reasonable structural design.

[0044] The upper cutter 25 is mounted on the cutter holder 24 by bolts, and can be easily disassembled and replaced.

[0045] Example 4: Reference Figure 1-Figure 7 , a cutting device with a detection function for spring processing, which is basically the same as Example 3, and further: a second cylinder 32 is installed on the first cylinder 31, a mounting block 321 is installed on the telescopic end of the second cylinder 32, and a pressure sensor 322 is installed on the end surface of the mounting block 321; it also includes an arc-shaped upper cover plate 4 installed on the mounting table 1, and the arc-shaped upper cover plate 4 is fixedly connected with an extension plate 41 near the upper cutter 25, and the arc-shaped upper cover plate 4 is located above the material receiving seat 33 to cover the upper opening of the material receiving groove 34; a stop plate 42 is fixedly connected to the arc-shaped upper cover plate 4, and the stop plate 42 is located at the front end of the material receiving seat 33. The second cylinder 32 pushes the mounting block 321 to squeeze the spring located between the stop plate 42 and the mounting block 321, and the pressure sensor 322 measures the elastic force of the spring;

[0046] When the turntable 3 drives the receiving seat 33 to rotate to a position close to the upper cutter 25 and the lower cutter 26, the turntable 3 stops rotating, and the first cylinder 31 pushes the receiving seat 33 to further approach the upper cutter 25 and the lower cutter 26, so that the receiving seat 33 is close to the upper cutter 25 and the lower cutter 26. At this time, the feeding cylinder 16 feeds the spring between the upper cutter 25 and the lower cutter 26, and the extended spring will be located in the receiving groove 34 of the receiving seat 33. Then the first cylinder 31 drives the receiving seat 33 to retract, and the arc-shaped upper cover plate 4 can prevent the spring located in the receiving groove 34 from accidentally falling out. At the same time, the setting of the extension plate 41 can also prevent the spring from accidentally falling out when cutting the spring.

[0047] Then the upper cutter 25 cuts the spring, and the cut spring remains in the receiving groove 34. Then the turntable 3 continues to rotate. At this time, there is a receiving seat 33 of the spring in the receiving groove 34, and one end thereof faces the abutment plate 42. When one end of the receiving seat 33 faces the abutment plate 42, the second cylinder 32 pushes the mounting block 321 to squeeze the spring in the receiving groove 34. When the telescopic end of the second cylinder 32 extends to the set length, it stops. At this time, the pressure sensor 322 in contact with one end of the spring measures the thrust transmitted by the spring to the pressure sensor 322, and then detects whether the elastic force of the spring meets the requirement.

[0048] After the inspection is completed, the qualified springs will be pushed into the first material guide plate 5 by the second cylinder 32 when the receiving seat 33 passes through the first material guide plate 5, and the qualified springs will slide from the first material guide plate 5 to the collection box below;

[0049] The unqualified springs will be pushed into the second material guide plate 6 by the second cylinder 32 when the receiving seat 33 passes through the second material guide plate 6, and enter the unqualified collection box for collection;

[0050] Therefore, the device can perform elastic force detection on the cut springs while cutting the springs, and can automatically classify and collect qualified and unqualified springs. Compared with the spring cutting method of the prior art, the device can collect the cut springs well, avoiding the change of the force position of the spring when the upper cutter 25 cuts the spring due to the different contact positions between the upper cutter 25 and the spring, which causes splashing after cutting.

[0051] Furthermore, a mounting groove 350 is provided in the material receiving groove 34, and a rotating drum 35 is rotatably connected in the mounting groove 350, and the outer periphery of the rotating drum 35 extends into the material receiving groove 34;

[0052] A rubber wheel 352 is fixedly connected to one end of the rotating drum 35 close to the mounting block 321, a spiral groove 351 is provided on the outer circumference of the rotating drum 35, a first friction pad 353 is installed on the mounting platform 1 above the turntable 3, the first friction pad 353 is located between the mounting frame 2 and the turntable 3, and the rubber wheel 352 corresponds to the first friction pad 353; a second friction pad 354 is installed on the mounting platform 1 above the turntable 3, and the second friction pad 354 corresponds to the rubber wheel 352;

[0053] When the cut spring is in the receiving groove 34, the rotation of the turntable 3 causes the rubber wheel 352 on the rotating drum 35 to contact the first friction pad 353 first, and the rotating drum 35 rotates under the action of the friction force. The spiral groove 351 makes the spring just dropped in the receiving groove 34 move further toward the first cylinder 31 under the rotation of the rotating drum 35, thereby preventing one end of the spring from leaking out of the receiving seat 33, thereby further preventing the spring from falling from the receiving seat 33.

[0054] After the rubber wheel 352 is separated from the first friction pad 353, the first cylinder 31 pushes the spring to perform the test;

[0055] Then the rubber wheel 352 contacts the second friction pad 354 again, so that the squeezed spring rotates in the receiving groove 34, so that the spring is tested for spring force again in the rotating state.

[0056] It should be noted that the connection between the first cylinder 31 and the second cylinder 32 and the external air pipe is achieved through a rotating pipe adapter, so there is no need to worry about the rotation of the turntable 3 causing failure to supply air to the first cylinder 31 and the second cylinder 32;

[0057] Secondly, the pressure sensor 322 is connected via a rotating connector, and there is no need to worry about the problem of the cable being unable to connect.

[0058] Example 5: Reference Figure 1-Figure 7 , a spring cutting method mainly comprises the following steps:

[0059] S1, the feeding cylinder 16 conveys the spring located on the mounting plate 11 to between the upper cutter 25 and the lower cutter 26, and the spring extending from the upper cutter 25 and the lower cutter 26 is located in the receiving groove 34;

[0060] S2, the upper cutter 25 moves downward to cut the spring, and the cut spring falls into the receiving trough 34, and then the turntable 3 rotates;

[0061] S3, the rotating turntable 3 brings the receiving seat 33 to the abutment plate 42, the spring is pushed by the second cylinder 32 to be squeezed, and the elastic force of the spring is measured by the pressure sensor 322;

[0062] S4. The springs that meet the elastic force requirements fall into the first guide plate 5, and the springs that do not meet the elastic force requirements fall into the second guide plate 6.

[0063] The present invention can automatically convey the spring located on the mounting plate 11 between the upper cutter 25 and the lower cutter 26 through the intermittent rotation of the feeding cylinder 16, and the upper cutter 25 moves downward to cooperate with the cutting edge of the lower cutter 26 to cut the spring, and the cut spring located in the receiving seat 33 is transposed by the rotation of the turntable 3. During the transposition process, the spring in the receiving seat 33 is driven to be squeezed, and the elastic force of the compressed spring is measured by the pressure sensor 322, and then the elastic force performance of the cut spring is tested to avoid the cut spring elastic force not meeting the requirements;

[0064] Moreover, the device can detect the elastic force of the cut springs while cutting them, and can automatically classify and collect qualified and unqualified springs. Compared with the spring cutting method of the prior art, the device can collect the cut springs well, avoiding the change of the force position of the spring when the upper cutter 25 cuts the spring due to the different contact positions between the upper cutter 25 and the spring, which causes splashing after cutting.

[0065] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the present invention can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
