Description

Technical Field

[0002] The reel is a cylindrical structure accessory, which has a very wide range of applications, such as as a part of a chemical container, as a sleeve of a large mechanical accessory, as a wheel hub for a tire, etc. During the production and processing, after the reel is processed by large mechanical equipment, such as a plate rolling machine, it is necessary to test the reel's ovality, centrality and other parameters.

[0003] At present, laser rangefinders are mostly used for detection. However, due to the heavy weight of the cylinder, especially the heavy cylinder, the cylinder must be lifted out of the plate rolling machine before measurement due to the physical limitations of the rangefinder. However, this method obviously requires a large amount of construction, and once the measurement fails, the roll needs to be re-suspended and installed on the plate rolling machine for processing again. After processing, the material is unloaded for inspection again, and this is repeated, and the workload of measurement is very large.

[0004] In addition, since the temperature of the roll surface is very high during roll processing, it is necessary to wait for the roll to cool down naturally before unloading. Obviously, it takes a lot of time for the high-temperature roll to cool down naturally to a specific low temperature. Therefore, in actual working process, measuring the processed roll in this way is not only very inefficient, but also time-consuming and labor-intensive, and the measurement workload is very large.

[0040] Example 1

[0041] like Figure 1-5 As shown, a roll measuring device includes a measuring frame rod 24, which is shaped like a horizontally arranged frame rod body, and a vertical frame rod body is integrally arranged upward vertically. The vertical frame rod body is fixedly connected to the mounting plate, and is installed in an existing manner. During the measurement process, it is supported on the ground by the mounting plate.

[0042] The front end of the measuring frame rod 24 is connected with a measuring roller mechanism 2. The specific structure of the measuring roller mechanism 2 is as follows:

[0043] The measuring roller mechanism 2 includes a measuring wheel 21, which is assembled and connected with an elastic telescopic rod assembly. During the measurement process, the elastic telescopic rod assembly elastically contacts the side wall of the reel; the elastic telescopic rod assembly is fixedly connected with a driving rod 27, and the driving rod 27 is assembled and connected with a recording pen corresponding to the paper roll recording mechanism. During the measurement process, the elastic telescopic rod assembly carries the recording pen to continuously move back and forth horizontally. During the movement, the recording pen 28 records the movement trajectory on the paper roll recording mechanism.

[0044] Specifically, according to the existing conventional method, the measuring wheel 21 is rotatably connected to the wheel frame 22, and the elastic telescopic rod assembly includes a telescopic long rod 23 fixedly connected to the wheel frame 22, and the telescopic long rod 23 is slidably connected to the spring tube 26 (the top of the above-mentioned spring tube 26 is fixedly connected to the fixed seat 241, and the fixed seat 241 is fixedly connected to the top of the measuring frame rod 24).

[0045] At the same time, the front end of the driving rod 27 is fixedly connected to a driving plug seat 272 that is slidably connected to the spring barrel 26; the telescopic long rod 23 is fixedly connected to the driving plug seat 272 (the driving plug seat 272 is in the shape of a flat cylinder and slides in the barrel cavity of the spring barrel 26). At the same time, the spring barrel 26 is provided with two sections of springs 25 that are respectively fixedly connected to the side walls of the driving plug seat 272 on both sides (the other end of the spring 25 is fixed to the end position in the spring barrel 26).

[0046] Correspondingly, a long rectangular sliding opening adapted to the driving rod 27 is opened on the spring tube 26 , and the driving rod 27 passes through the long rectangular sliding opening and is fixedly connected to the driving plug seat 272 .

[0047] At the same time, the rear end of the driving rod 27 is fixedly connected to a connecting plate 271, the connecting plate 271 is fixedly connected to a sliding frame 29 slidably connected to the measuring frame rod 24, and the recording pen 28 is fixedly connected to a fixed plate 281 installed on the top of the sliding frame 29. Therefore, when the driving rod 27 moves back and forth, the sliding frame 29 carries the recording pen 28 to move back and forth.

[0048] During the inspection process, the roll 1 being processed is rotated by driving the curling machine by unloading, and at this time, the measuring wheel 21 is elastically pressed against the roll 1 (the spring 25 on one side is compressed and the spring 25 on the other side is stretched). Since the roundness of the roll 1 is easy to be irregular during processing, when the roundness of the roll 1 is irregular, at this time, under the resistance of the roll 1, the measuring wheel 21 continuously carries the telescopic long rod 23 to move back and forth (forward and backward), and at the same time, the telescopic long rod 23 carries the drive plug seat 272 to move back and forth elastically, and the drive plug seat 272 carries the drive rod 27 to move back and forth (in this process, the drive rod 27 slides on the long rectangular slide of the spring tube 26), and the drive rod 27 carries the recording pen 28 to move back and forth.

[0049] In this way, the recording pen 28 is associated with the rotation of the reel 1, and during the rotation of the reel 1, the horizontal reciprocating motion of the recording pen 28 is associated with the circularity of the reel 1, that is, when the circularity of the reel 1 is irregular, the recording pen 28 can be caused to move accordingly.

[0050] In order to record the motion trajectory of the recording pen 28, the other end of the measuring frame rod 24 is equipped with a roll paper recording mechanism corresponding to the measuring roller mechanism 2. Specifically, the roll paper recording mechanism is used to unwind the roll paper corresponding to the recording pen 28. During operation, the recording pen 28 draws the motion trajectory on the roll paper.

[0051] Example 2

[0052] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the above-mentioned paper roll recording mechanism 3 includes a gear transmission assembly.

[0053] Specifically, the gear transmission assembly includes a driving gear 31 fixedly connected to one side of the measuring wheel 21 (the rotation of the measuring wheel 21 drives the driving gear 31 to rotate, and the specific method is the same as the existing method. The driving gear 31 is fixedly installed on the axle of the measuring wheel 21. The rotation of the measuring wheel 21 drives the axle to rotate on the wheel frame 22, and the driving gear 31 is driven by the axle to move in a circle). Correspondingly, the driving gear 31 is meshed with a driven gear 32 (both are bevel gears).

[0054] At the same time, the driven gear 32 is fixedly connected with a long shaft rod 33 , and correspondingly, a convex plate rotatably connected with the long shaft rod 33 is fixedly connected to the wheel frame 22 .

[0055] The above-mentioned paper roll recording mechanism 3 also includes a paper roll 36 that slides on the long shaft rod 33. During the rotation of the long shaft rod 33, the paper roll 36 is carried to rotate. During the rotation of the paper roll 36, the wound recording paper is unwound (the recording paper is wound on the cylinder mentioned below), and it interacts with the recording pen 28 to draw the movement trajectory of the recording pen 28.

[0056] Specifically, since the measuring wheel 21 carries the telescopic rod to move back and forth during the detection process (the measuring wheel 21 moves back and forth), therefore, during the high-speed rotation process, since the active gear 31 meshes with the driven gear 32, and the meshing force is large, the reciprocating movement of the measuring wheel 21 carries the active gear 31 and the meshed driven gear 32 to move back and forth (in the high-speed movement state, since the meshing force of the active gear 31 meshing with the driven gear 32 is large, the friction force that needs to be overcome for the relative horizontal slip and dislocation of the active gear 31 and the driven gear 32 is very large, resulting in the reciprocating movement of the measuring wheel 21, carrying the active gear 31 and the driven gear 32 to move back and forth (that is, the active gear 31 and the driven gear 32 move back and forth synchronously, and the two are not easy to slip relative to each other), and there will be no relative slip between the two, and the meshing situation will not easily occur). And since the amplitude of the reciprocating movement of the measuring wheel 21 is not very large (the overall shape of the reel 1 is regular, even if it is irregular, the amplitude of the irregularity after the plate rolling machine is processed is not particularly large), therefore, the active gear 31 and the driven gear 32 are not easy to dislocate and disengage.

[0057] Even if the two become disengaged during operation, the operator can correct them manually and re-engage them (the measuring device disclosed in the utility model is a temporary emergency measuring device, which can detect obvious irregular shapes of the reel 1 during production).

[0058] During the horizontal sliding process of the long shaft rod 33 , it slides horizontally relative to the recording paper roll; specifically, the paper roll 36 is rotatably connected to the mounting bracket 35 , and the mounting bracket 35 is fixedly connected to the measuring frame rod 24 .

[0059] The shape of the paper reel 36 is:

[0060] The paper roll 36 includes a cylinder body, in which a sleeve shaft 361 is fixedly connected, and the sleeve shaft 361 is rotatably connected to the mounting frame 35; the long shaft rod 33 is limited in the shaft cavity of the sleeve shaft 361. The shaft cavity of the sleeve shaft 361 includes a cylindrical cavity portion rotatably connected to the long shaft rod 33, and the cylindrical cavity portion is integrally formed with a protruding limiting cavity portion 3611 (the longitudinal cross-section of the limiting cavity portion 3611 is rectangular).

[0061] Correspondingly, the above-mentioned long shaft rod 33 is fixedly connected with a convex sliding seat 34 which is slidably connected in the limiting cavity 3611. During the rotation of the long shaft rod 33, the convex sliding seat 34 is limited in the limiting cavity 3611, carrying the cylinder to rotate. During the horizontal sliding of the long shaft rod 33, the convex sliding seat 34 slides horizontally in the limiting cavity 3611.

[0062] Therefore, when the long shaft rod 33, the measuring wheel 21, the driving gear 31 and the driven gear 32 move horizontally synchronously, the convex sliding seat 34 slides horizontally in the limiting cavity 3611, thereby not affecting the reciprocating horizontal movement of the entire device.

[0063] During the reciprocating horizontal movement, the convex sliding seat 34 is still limited in the limiting cavity 3611, and the paper roll 36 follows the rotation to unwind the recording paper (according to the existing method, the other end of the recording paper is pulled by the operator by hand or fixed to the winding machine, and is wound by the winding machine, such as a winding shaft or motor structure).

[0064] During the detection process implemented in the above manner, the recording paper is continuously unrolled to record the motion trajectory on the recording paper in coordination with the trajectory movement of the recording pen 28, thereby reflecting the regularity of the shape of the roll 1. For example, during the detection process, the irregularity of the recorded trajectory curve is very large, and the horizontal reciprocating motion of the surface recording pen 28 is seriously irregular, thereby indicating that the shape of the surface roll 1 is seriously irregular.

[0065] By adopting the above-mentioned device, during the processing of the roll 1, there is no need to unload the heavy or high-temperature roll 1 and test it after cooling. During the processing, the roll 1 can be directly driven to rotate by the processing roll 1 equipment. With the device disclosed in the utility model, the roll 1 can be easily, quickly and efficiently tested. This testing method is not only efficient, but also relatively accurate, and can intuitively and effectively determine the shape characteristics of the roll 1.

[0066] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
