And the rotation of the can 10 is facilitated due to the rotatable design of the roller 231.

Referring to fig. 3, the adjusting component 220 is disposed on one side of the traversing bracket 210 and is in transmission connection with the traversing bracket 210, and the adjusting component 220 can drive the traversing bracket 210 to move transversely relative to the calibration platform 100.

By the threaded engagement of the lateral adjustment nut 223 and the lateral adjustment screw 222, the lateral bracket 210 is driven to move laterally when the lateral adjustment screw 222 is rotated.

In other embodiments, the adjustment member 220 may comprise a motorized push rod, the push rod end of which is coupled to the traversing carriage 210 such that the motorized push rod may drive the traversing carriage 210 to move laterally. Alternatively, the adjusting member 220 may include a hydraulic cylinder or air cylinder, the piston rod end of which is connected to the traverse bracket 210, so that the hydraulic cylinder or air cylinder can drive the traverse bracket 210 to move laterally.

Referring to fig. 4 to 6, the calibration platform 100 is further provided with a height adjustment mechanism 300, and the height adjustment mechanism 300 can adjust the vertical height position of the tank 10 relative to the calibration platform 100.

In some embodiments, the height adjustment mechanism 300 includes a base 310, an adjustment carriage 320, and a drive member 330, as well as a roller set 340.

The base 310 is fixedly mounted on the calibration platform 100, and the base 310 is provided with an adjusting inclined plane which is arranged at an included angle with the height direction. The adjusting sliding seat 320 is arranged on the base 310, the adjusting sliding seat 320 is provided with a matching surface corresponding to the adjusting inclined surface, and the matching surface is arranged in parallel with the adjusting inclined surface.

The driving component 330 is in transmission connection with the adjusting sliding seat 320, and the driving component 330 can drive the adjusting sliding seat 320 to slide along the adjusting inclined plane relative to the base 310. Wherein, the driving part 330 includes an adjusting nut 331 and a driving screw 322, the adjusting nut 331 is fixedly arranged on the adjusting slide 320, one end of the driving screw 322 is rotatably arranged on the base 310, and the other end of the driving screw 322 is in threaded connection with the adjusting nut 331.

Further, a roller set 340 is further disposed between the base 310 and the adjusting slide 320, and the roller set 340 is composed of a plurality of rollers side by side. Each roller can be in rolling contact with the matching surface and the adjusting inclined surface respectively. The roller group 340 is arranged to change the relative sliding motion between the base 310 and the adjusting slide 320 into the relative rolling motion, so that the contact friction force is changed into the rolling friction force, the resistance of the adjusting slide 320 to move up and down is reduced, and the smoothness of the height adjustment of the tank 10 is improved.

In some embodiments, a limiting portion is further disposed on the calibration platform 100 for limiting the range of movement of the adjustment slide 320 relative to the base 310. For example, the limiting part is a limiting rod 120, the lower end of the limiting rod 120 is connected to the calibration platform 100, and the other end of the limiting rod passes through the base 310 and the adjusting slide 320 in sequence. Correspondingly, a through hole can be formed on the base 310 corresponding to the limiting rod 120, a kidney-shaped hole 321 can be formed on the adjusting sliding seat 320 corresponding to the limiting rod 120, and the limiting rod 120 sequentially penetrates through the through hole and the kidney-shaped hole 321. The limit rod 120 is matched with the through hole and the kidney-shaped hole 321, so that the limit of the range of up-and-down movement of the adjusting slide 320 relative to the base 310 can be realized.

In some embodiments, the traversing carriage 210 is supported on the alignment platform 100 by a height adjustment mechanism 300. In detail, the traverse bracket 210 is connected to the upper surface of the adjustment slider 320, the traverse bracket 210 can move up and down with respect to the alignment platform 100 as being follower to the adjustment slider 320, and the adjustment member 220 can drive the traverse bracket 210 to move laterally with respect to the adjustment slider 320. In this example, the other end of the stop lever 120 may pass through the base 310 and the adjustment slider 320 in order upward and may be connected to the traverse bracket 210.

Further, a transverse limiting structure 500 may be disposed between the transverse moving rack 210 and the alignment platform 110, where the limiting structure 500 is used to limit a path of transverse movement of the transverse moving rack 210, so as to prevent the transverse moving rack 210 from shifting along the axial direction of the can 10 during the transverse moving process. The spacing structure 500 may take a variety of forms: for example, the limiting structure 500 includes a first limiting portion 510 and a second limiting portion 520 disposed on the calibration platform 110, where the first limiting portion 510 and the second limiting portion 520 are disposed on opposite sides of the traversing support 210, and two sides of the traversing support 210 can respectively contact against the first limiting portion 510 and the second limiting portion 520. In an embodiment, the first limiting portion 510 may be a guiding wheel disposed on one side of the traverse support 210, and the second limiting portion 520 is a guiding wheel disposed on the other side of the traverse support 210. The guide wheels on both sides of the traversing carriage 210 can be disposed in pairs.

In other embodiments, the limiting structure 500 may also be a guide hole and a guide rod respectively disposed on the traversing bracket 210 and the alignment platform 100, where the guide hole extends along a lateral direction, and the guide rod is disposed through the guide hole.

As shown in fig. 3, when the height adjusting mechanism 300 adjusts the height of the tank 10 up and down, the traversing bracket 210 is suspended relative to the calibration platform 100. The translational adjustment mechanism 200 further includes a support bracket 240 in view of the stability of the support of the tank 10. One end of the support bracket 240 is connected with the traversing bracket 210, and the other end of the support bracket 240 can be abutted against the calibration platform 100. Specifically, the support bracket 240 includes a support bar having an upper end connected to the bottom of the traverse bracket 210 and a support foot connected to a lower end of the support bar in an up-down adjustable manner. For example, the supporting feet are in threaded connection with the lower ends of the supporting rods, after the height of the tank body 10 is adjusted in place by the height adjusting mechanism 300, the supporting feet are adjusted up and down according to the distance between the current transverse moving support 210 and the calibration platform 100, so that the supporting feet can be propped against the upper surface of the calibration platform 100, the supporting support 240 can play a role in supporting the transverse moving support 210, and the stability of supporting the tank body 10 is improved.

In addition, since the traversing carriage 210 can move up and down along with the height adjusting mechanism 300, the aforementioned traversing adjusting screw 222 connected to the traversing carriage 210 will interfere with the fixing base 221. To solve the interference problem, the top of the fixing base 221 is provided with an upward opening. When the lateral position of the can 10 needs to be adjusted, the end of the lateral adjusting screw 222, which is far away from the lateral bracket 210, can be set to be positioned at the top of the fixing base 221 by the lateral clamp of the opening, and can rotate relative to the fixing base 221. And then the transverse moving bracket 210 is driven to transversely move by rotating the transverse adjusting screw 222.

After the transverse position of the tank 10 is adjusted, when the height of the tank 10 needs to be adjusted, the end of the transverse adjusting screw 222, which is far away from the transverse moving bracket 210, can be separated from the fixing seat 221 from the opening in the process that the transverse moving bracket 210 moves upwards along with the height adjusting mechanism 300, so that the tank 10 can be adjusted to a proper height according to the needs.

Referring to fig. 7, the axis positioning mechanism 400 is disposed on the calibration platform 100 and located on the axial end side of the can 10. In detail, the can 10 has opposite front and rear ends in the axial direction, the axis positioning mechanisms 400 are respectively provided in two groups, and the two groups of axis positioning mechanisms 400 are respectively provided at the front side of the front end and the rear side of the rear end of the can 10. In the present embodiment, the translation adjusting mechanism 200 and the height adjusting mechanism 300 correspond to a bottom frame structure capable of supporting the can 10, and the two sets of axis positioning mechanisms 400 correspond to end frame structures capable of supporting two ends of the can 10, so that the translation adjusting mechanism 200, the height adjusting mechanism 300 and the axis positioning mechanisms 400 together define a placement space of the can 10 having a substantially rectangular parallelepiped shape.

Further, the axle center positioning mechanism 400 includes a positioning thimble 410, and a central axis of the positioning thimble 410 is parallel to the alignment axis 110. That is, by aligning the central axis of the can 10 with the central axis of the positioning thimble 410, the central axis of the can 10 is parallel to the reference line, and the axis alignment of the can 10 is completed.

In addition, the center axis of the can 10 can be overlapped with the center axis of the positioning thimble 410 by the adjustment of the translation adjusting mechanism 200 and the height adjusting mechanism 300.

In some embodiments, the manner in which the central axis of can 10 coincides with the central axis of locating thimble 410 may be: the positioning thimble 410 is disposed at one side of the end of the can 10, and the positioning thimble 410 can be inserted into a central positioning hole of the end of the can 10 in a direction parallel to the central axis of the can 10. As the name implies, the center locating hole of the end of the can 10 is a hole whose center coincides with the center axis of the can 10. Positioning thimble 410 can be inserted into the positioning hole such that the center axis of positioning thimble 410 coincides with the center of the positioning hole. Wherein, the positioning thimble 410 is preferably cylindrical, and the positioning hole is preferably a circular hole matched with the outer Zhou Shi of the positioning thimble 410. In addition, the end of the positioning thimble 410 may be needle-tip-shaped, so that the positioning thimble 410 may be easily inserted into the positioning hole.

It will be appreciated that the center of the circular hole is the center of the locating hole, and the center of the locating hole coincides with the central axis of the tank 10. When the positioning thimble 410 is vertically inserted into the positioning hole, the central axis of the positioning thimble 410 coincides with the center of the positioning hole, so that the central axis of the can 10 coincides with the central axis of the positioning thimble 410. In addition, the positioning thimble 410 is inserted into the positioning hole, so that the axis positioning mechanism 400 not only can calibrate the axis of the tank 10, but also can be positioned and connected with two ends of the tank 10 to stably support the tank 10. Thereby facilitating the operation of rotating the can body 10 and the like in the process of equally dividing and scribing the peripheral surface of the subsequent can body 10.

In this example, the process of alignment of the axis of the tank 10 is generally: the can 10 is laid down on the roller 231 of the traverse bracket 210. The axis positioning mechanism 400 is positioned and installed at both ends of the calibration platform 100 according to the length of the tank 10. Checking whether the positioning hole at the end of the can 10 is aligned with the needle point of the positioning thimble 410 of the axis positioning mechanism 400. If not, the horizontal position and the height position of the can body 10 are adjusted by the translation adjusting mechanism 200 and the height adjusting mechanism 300, so that the positioning hole at the end part of the can body 10 is aligned with the positioning thimble 410, and the purpose that the central axis of the can body 10 coincides with the central axis of the positioning thimble 410 can be achieved.

In some embodiments, hub positioning mechanism 400 further includes a positioning bracket 420, a drive rod 430, and a fixed sleeve 440.

The positioning bracket 420 is fixedly mounted on the calibration platform 100. It should be noted that, when the positioning bracket 420 is fixedly mounted to the calibration platform 100, it is required to ensure that the central axis of the positioning thimble 410 thereon is parallel to the calibration axis 110.

Preferably, the positioning block 450 is disposed at the bottom of the positioning bracket 420. The alignment platform 100 is provided with a positioning slot (i.e., the aforementioned linear slot) extending along the alignment axis 110. The positioning block 450 may be in a bar shape, and can be clamped into the positioning groove, so that positioning and mounting of the positioning bracket 420 relative to the calibration platform 100 can be realized, and positioning of the positioning thimble 410 on the positioning bracket 420 can be realized. In other words, the positioning block 450 and the positioning groove cooperate to position the positioning thimble 410 such that the central axis of the positioning thimble 410 is parallel to the calibration axis 110.

Referring to FIG. 7, positioning thimble 410 is movably coupled to the top of positioning bracket 420 along its own axis. In detail, the positioning thimble 410 is connected to one end of the driving rod 430. The length extension direction of the driving rod 430 is parallel to the alignment axis 110, and the driving rod 430 is movably disposed on top of the positioning bracket 420 along its length extension direction.

Center axis coincides with center axis of drive rod 430 when positioning thimble 410 is connected to the end of drive rod 430. Thus, movement of the drive rod 430 will move the positioning thimble 410 toward the can 10 and ensure that the central axis of the positioning thimble 410 is always parallel to the alignment axis 110. By arranging the positioning thimble 410 at the end of the driving rod 430, the driving rod 430 is convenient to drive the positioning thimble 410 to move towards one side of the can body 10, so that the positioning thimble 410 can be inserted into a positioning hole at the end of the can body 10, and the axial line of the can body 10 is adjusted.

Preferably, the positioning thimble 410 is connected to the end of the driving rod 430 through shaft hole matching. So that the positioning pins 410 can rotate and move relative to the driving rod 430 to accommodate the rotation of the can 10.

Further, the driving rod 430 may be a screw. The screw can be screw-fitted with a screw nut 441 on the fixing sleeve 440. The fixed sleeve 440 is fixedly mounted at the top of the positioning bracket 420, and the screw rod can be penetrated into the fixed sleeve 440 through the screw rod nut 441, and both ends of the screw rod extend outwards. The positioning thimble 410 is connected to the end of the screw rod near the tank 10, and a wrench for rotating the screw rod conveniently can be arranged at the other end of the screw rod.

In this example, the screw is turned by a wrench to bring the positioning thimble 410 close to the end of the can 10, and whether the positioning hole of the end of the can 10 is aligned with the end of the positioning thimble 410 is checked. Misalignment moves the can 10 up and down and horizontally laterally by the height adjustment mechanism 300 and the translation adjustment mechanism 200, respectively, until the locating thimble 410 is fully aligned with the locating hole in the end of the can 10. Then, the screw rod is rotated to enable the positioning thimble 410 to be inserted into the positioning hole at the end part of the can body 10, and at the moment, the central axis of the can body 10 coincides with the central axis of the positioning thimble 410.

According to the tank axis calibration device, the tank 10 placed in a lying state can be installed and supported and axis calibrated, and then the circumferential surface of the tank 10 can be equally divided and marked. Wherein the step of axis calibration comprises: the horizontal position of the tank body 10 relative to the calibration platform 100 is adjusted through the translation adjusting mechanism 200, and the vertical height position of the tank body 10 relative to the calibration platform 100 is adjusted through the height adjusting mechanism 300, so that the central axis of the tank body 10 coincides with the central axis of the positioning thimble 410.

In detail, the can 10 is laid down on the roller 231 of the traverse bracket 210. Rotating the wrench rotates the lead screw so that the locating thimble 410 can be located near the end of the can 10. Check if the locating hole in the end of can 10 is aligned with locating thimble 410. When the tank body 10 is misaligned, the driving screw 322 drives the adjusting slide seat 320 to move up and down so as to adjust the height position of the tank body 10. And the transverse moving bracket 210 is driven to move transversely by the transverse adjusting screw 222 to adjust the transverse position of the can body 10 until the positioning thimble 410 is aligned with the positioning hole at the end of the can body 10. Then, the screw rod is rotated to enable the positioning thimble 410 to be inserted into the positioning hole at the end part of the can body 10, and at the moment, the central axis of the can body 10 coincides with the central axis of the positioning thimble 410.

After the central axis of the can 10 coincides with the central axis of the positioning thimble 410, the method further comprises the following steps:

first scribing: a first line segment is drawn along the axial direction of the can body 10 at one side of the can body 10, and the first line segment has a predetermined horizontal height. Specifically, referring to fig. 3, the predetermined level is a level that can coincide with a level at which the central axis of the can 10 is located. In actual operation, the first line segment may be drawn on the left side surface of the can body 10 by using the height gauge in combination with the drawing needle.

Second scribing: a second line segment is drawn on the opposite side of the can body 10 in the axial direction of the can body 10 at the same level as the first line segment. Where the opposite side of the can 10 refers to the other side of the can 10 opposite the location of the first line segment, such as the right side in fig. 3.

In actual operation, the second line segment can be drawn on the right side surface of the tank body 10 at the same horizontal height by utilizing the height ruler and the scriber, and the horizontal height of the second line segment coincides with the horizontal plane of the central axis of the tank body 10. That is, the central angle of the surface of the can body 10 spaced between the second line segment and the first line segment is 180 °, and the first line segment and the second line segment bisect the peripheral surface of the can body 10.

Third scribing: a third line segment is drawn at the bottom of the can body 10 along the axial direction of the can body 10. As shown in fig. 3, the bottom of the can 10 is the lowest point of the surface of the can 10 in the vertical direction. That is, the first line segment, the second line segment, and the third line segment at this time are respectively located at the left 0 ° position, the right 180 ° position, and the bottom 90 ° position on the circumferential surface of the can 10.

Fourth scribing: after rotating the tank body by 180 degrees and repeating the step of axis calibration, a fourth line segment is drawn at the bottom of the tank body 10 along the axial direction of the tank body 10. It will be appreciated that when the can 10 is rotated 180 ° after the first, second and third line segments are drawn, the top of the can 10 will now be rotated to the bottom, thereby facilitating the drawing of a fourth line segment at the bottom of the can 10. And, rotate the jar body 10 and repeat the step of above-mentioned axis calibration after 180, can effectively guarantee jar body 10 positional accuracy, improve jar body 10 circumference halving's precision.

After the steps, the line marking of each equal-dividing line segment on the circumferential surface of the tank body 10 is completed, and then the position of the component to be installed on the surface of the tank body 10 can be determined according to each equal-dividing line segment, so that the installation precision of the component on the surface of the tank body 10 is improved, and the product quality is improved.

In one embodiment, in the fourth scribing step, after repeating the axis calibration step, before scribing the fourth wire segment, the method further includes the steps of: the level of the first line segment and the level of the second line segment are measured separately. After the level of the first line segment and the level of the second line segment are measured, the level of the first line segment and the level of the second line segment are compared. If the two are consistent, the subsequent operation can be continued, namely, a fourth line segment is drawn.

If the level of the first line segment is not consistent with the level of the second line segment, the tank 10 is rotated until the level of the first line segment is consistent with the level of the second line segment. Therefore, the position of the fourth line segment can be ensured to be positioned at the middle position between the first line segment and the second line segment, the dividing and scribing of the circumferential surface of the tank body 10 can be realized, and the accuracy of the circumferential dividing of the tank body 10 can be improved.

In one embodiment, after the fourth scribing step, further comprising: after the tank 10 is rotated by 90 ° and the axis calibration step is repeated, the level of the third line segment and the level of the fourth line segment are measured. In this example, after the dividing and scribing of the circumferential surface of the can body 10 is completed, the accuracy of scribing of the fourth line segment can be known by measuring the horizontal heights of the third line segment and the fourth line segment, and the dividing and scribing can be used as the data reference of the subsequent operation.
