Description

The auxiliary adjusting device is located between the main roller and the tension arm device. The diamond wire is arranged neatly by the take-up device and the wire arranging device and then is transmitted to the tension arm device. The tension arm device adds tension to the diamond wire and then transmits the diamond wire to the auxiliary adjusting device. The relative position of the diamond wire and the main roller is adjusted by the auxiliary adjusting device according to the length of the material and then the diamond wire is transmitted to the main roller.

[0003] A guide groove is arranged on the auxiliary adjusting device. When the relative position of the diamond wire and the main roller is adjusted, the diamond wire needs to be kept at the center position of the guide groove to ensure that the diamond wire is at the preset position. However, in the actual production process, the operator only confirms whether the diamond wire is at the preset position by visual observation, which leads to a large adjustment error and makes it difficult to adjust to the right position. At the same time, due to the poor cutting environment, the guide mechanism used for adjusting the position of the diamond wire is prone to precision deviation, which further increases the adjustment error.

[0024] In order for those skilled in the art to better understand the scheme of the application, the technical scheme in the specific embodiment of the application will be described clearly and completely below in combination with the drawings in the embodiment of the application. It should be understood that those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the application.

[0025] As Figure 1As shown, an auxiliary adjustment device 100 is used to adjust the diamond wire of a cutting device to a preset position so that the diamond wire is tangent to the main roller and the extension direction of the diamond wire is perpendicular to the extension direction of the main roller axis. The auxiliary adjustment device 100 includes a guide rail mechanism 11, a moving mechanism 12, a rotating mechanism 13, a guide wheel mechanism 14, and a calibration mechanism 15. The moving mechanism 12 and the guide rail mechanism 11 are slidably connected, and the rotating mechanism 13 is at least partially rotatably connected to the moving mechanism 12. The calibration mechanism 15 is at least partially disposed on the rotating mechanism 13, specifically, as shown in... Figure 7 As shown, the calibration mechanism 15 includes a mounting component 151 and a calibration component 152. The mounting component 151 is fixedly connected to the rotating mechanism 13. The calibration component 152 is mounted on the mounting component 151, and its position relative to the mounting component 151 is adjustable. The diamond wire is adjusted to a preset position by sliding the moving mechanism 12 relative to the guide rail mechanism 11 and rotating the rotating mechanism 13 relative to the moving mechanism 12, and by adjusting the position of the calibration component 152 relative to the mounting component 151. The guide wheel mechanism 14 is rotatably connected to the rotating mechanism 13, and at least partially wound around the guide wheel mechanism 14. The guide wheel mechanism 14 is used to guide the movement of the diamond wire.

[0026] like Figure 1 As shown, the auxiliary adjustment device 100 includes a guide mechanism 16, which is fixedly connected to a rotating mechanism 13. The guide mechanism 16 extends along a preset direction and is used to guide the diamond wire to be wound onto the main roller. When the diamond wire extends along the preset direction, it is in a preset position.

[0027] Specifically, the guide mechanism 16 comprises a first guide mechanism 161, one end of the first guide mechanism 161 is fixedly connected with the rotating mechanism 13, and the other end of the first guide mechanism 161 abuts against and is tangent to the main roller. The first guide mechanism 161 comprises a first end 1611 and a second end 1612, the first end 1611 is arranged at the end of the first guide mechanism 161 connected with the rotating mechanism 13, and the second end 1612 is arranged at the end of the first guide mechanism 161 abutting against the main roller, the direction from the first end 1611 to the second end 1612 is arranged as the extension direction of the first guide mechanism 161, and the first guide mechanism 161 extends along the preset direction. The first guide mechanism 161 can provide a guiding and calibrating effect for adjusting the diamond wire to the preset position, so that the position adjustment of the diamond wire is accurate and convenient. As an alternative implementation, the first guide mechanism 161 and the rotating mechanism 13 are detachably connected, and after the diamond wire is adjusted to the preset position, the first guide mechanism 161 can be detached from the rotating mechanism 13, so that the first guide mechanism 161 can be used to adjust the diamond wire of other cutting equipment, thereby improving the versatility of the first guide mechanism 161 and saving costs. Moreover, since the main roller rotates at high speed during work, this arrangement ensures that the main roller is not affected by the first guide mechanism 161 during work. At the same time, this arrangement also reduces the occupied space of the auxiliary adjusting device 100, thereby reducing the interference of the auxiliary adjusting device 100 and improving the safety of the auxiliary adjusting device 100. The guide mechanism 16 further comprises a second guide mechanism 162, and the second guide mechanism 162 is fixedly connected with the rotating mechanism 13. The second guide mechanism 162 is provided with a guide groove 1621, and the end of the diamond wire away from the guide roller mechanism 14 is located in the guide groove 1621 and is wound around the main roller after passing through the guide groove 1621. The guide groove 1621 extends along the preset direction, and the calibrating piece 152 calibrates the extension direction of the diamond wire. The guide groove 1621 plays a guiding role when the position of the diamond wire is adjusted, so that the position adjustment of the diamond wire is accurate and convenient. Moreover, the guide groove 1621 can serve as a position reference of the diamond wire. Since the diamond wire bears a large load during work, when the position of the diamond wire deviates from the preset position, the diamond wire is skewed and deviates from the preset direction. At this time, the position deviation of the diamond wire can be obtained according to the guide groove 1621, so that the diamond wire can be adjusted to the preset position in time, thereby avoiding the wear of the diamond wire between the guide groove 1621, which causes the diamond wire to fail and break, and improving the reliability of the diamond wire. At the same time, the guide groove 1621 can also prevent the diamond wire from interfering, thereby improving the safety of the diamond wire.

[0028] As Figure 2As shown, the moving mechanism 12 can slide on the guide rail mechanism 11 along the extension direction of the guide rail mechanism 11. Specifically, the moving mechanism 12 includes a fixed state and a sliding state, as an alternative embodiment, the moving mechanism 12 includes a first moving piece 121 and a first fastener 122, the first moving piece 121 is provided with a first connecting hole 1211, the first connecting hole 1211 is provided as a threaded hole, and the first fastener 122 is threadedly connected with the first connecting hole 1211. In the present application, the first fastener 122 includes a handle portion 1221 and a connecting portion 1222, the connecting portion 1222 is threadedly connected with the first connecting hole 1211, and the handle portion 1221 and the connecting portion 1222 are integrally formed. Rotating the handle portion 1221 can make the first fastener 122 abut against the guide rail mechanism 11 and generate a friction pre-tightening force between the first fastener 122 and the guide rail mechanism 11, so as to fix the moving mechanism 12 and the guide rail mechanism 11, at this time, the moving mechanism 12 is in the fixed state. Rotating the handle portion 1221 can also make the first fastener 122 separate from the guide rail mechanism 11, so that the moving mechanism 12 can slide along the extension direction of the guide rail mechanism 11, at this time, the moving mechanism 12 is in the sliding state.

[0029] As Figures 3 to 5As shown, the moving mechanism 12 further comprises a second moving piece 123, which is fixedly connected with or integrally formed with the first moving piece 121. The rotating mechanism 13 is rotatably connected with the second moving piece 123, and the guide wheel mechanism 14 is rotatably connected with the rotating mechanism 13, and the diamond wire is at least partially wound on the guide wheel mechanism 14. Specifically, the auxiliary adjusting device 100 comprises a second fastener (not shown in the figure), and the rotating mechanism 13 is provided with a second connecting hole 131, and the second moving piece 123 is provided with a third connecting hole 1231, and the second fastener at least partially passes through the second connecting hole 131 and the third connecting hole 1231 to fixedly connect the second moving piece 123 and the rotating mechanism 13. The rotating mechanism 13 is further provided with a fourth connecting hole 132, and the second moving piece 123 is further provided with a fifth connecting hole 1232, and the second fastener further at least partially passes through the fourth connecting hole 132 and the fifth connecting hole 1232 to fixedly connect the second moving piece 123 and the rotating mechanism 13. Among them, the fifth connecting hole 1232 is set as a crescent-shaped hole, according to the specific structure of the rotating mechanism 13 and the second moving piece 123, the second connecting hole 131, the third connecting hole 1231 and the fourth connecting hole 132 can be set as threaded holes or through holes. It can be understood that the axes of the second connecting hole 131 and the third connecting hole 1231 coincide, and by connecting the second fastener to different positions of the fifth connecting hole 1232, the rotating mechanism 13 can rotate around the axes of the second connecting hole 131 and the third connecting hole 1231, thereby realizing the rotating connection of the rotating mechanism 13 and the moving mechanism 12. Of course, the crescent-shaped hole provided on the second moving piece 123 is only one embodiment of the present application, and the technical scheme of realizing the rotating connection of the rotating mechanism 13 and the second moving piece 123 by providing a crescent-shaped hole on the rotating mechanism 13 is also within the protection scope of the present application.

[0030] As shown in Figure 6 The guide wheel mechanism 14 comprises a mounting seat 141 and a guide wheel 142, the mounting seat 141 is fixedly connected with or integrally formed with the rotating mechanism 13, and the guide wheel mechanism 14 is rotatably connected with the mounting seat 141. The guide wheel 142 is provided with an accommodating groove 1421, and the diamond wire is arranged in the accommodating groove 1421. The accommodating groove 1421 can prevent the diamond wire from separating from the guide wheel mechanism 14, so that the diamond wire has higher safety and reliability.

[0031] As shown in Figure 4 and Figure 7 The mounting piece 151 is fixedly connected with or integrally formed with the rotating mechanism 13, and the calibration piece 152 is fixedly connected to the rotating mechanism 13 through the mounting piece 151, so that the calibration mechanism 15 can move relative to the guide rail mechanism 11 together with the moving mechanism 12 and the calibration mechanism 15 can rotate relative to the moving mechanism 12 together with the rotating mechanism 13. The calibration piece 152 is connected with the mounting piece 151 and the displacement of the calibration piece 152 relative to the mounting piece 151 can be adjusted. In order to clearly illustrate the technical scheme of the present application, it is also defined thatFigure 7 The upper, lower, left, right, front, and back are shown. Specifically, the adjusting mechanism 1511 is arranged on the mounting member 151, and the adjusting mechanism 1511 can adjust the relative position between the calibration member 152 and the mounting member 151. The adjusting mechanism 1511 includes a first adjusting mechanism 1511a and a second adjusting mechanism 1511b. The first adjusting mechanism 1511a can cause the calibration member 152 and the mounting member 151 to produce a relative displacement in the left-right direction, and the second adjusting mechanism 1511b can cause the calibration member 152 and the mounting member 151 to produce a relative displacement in the front-back direction. In this way, the structure of the calibration mechanism 15 is simple and the cost is small, and the operation of the calibration mechanism 15 is convenient and practical. Through the above arrangement, the structure of the calibration mechanism 15 is simple and the cost is small, and the position of the calibration member 152 relative to the mounting member 151 is adjusted by the first adjusting mechanism 1511a and the second adjusting mechanism 1511b, so that the structure of the calibration mechanism 15 is simple and practical, and the operation is convenient. The calibration member 152 is arranged as a laser, and the relative position between the calibration member 152 and the mounting member 151 is adjusted by the adjusting mechanism 1511, so that the calibration member 152 can emit laser light extending in a predetermined direction to guide the diamond wire to the predetermined position. This arrangement uses the laser calibration method to make the diamond wire position adjustment have high linearity and strong accuracy.

[0032] The auxiliary adjusting device 100 includes an adjusting state and a fixed state. When the diamond wire has reached the predetermined position, the auxiliary adjusting device 100 is in the fixed state, and at this time the main roller can drive the diamond wire to rotate at high speed, so that the diamond wire can cut the material.

[0033] When the predetermined position needs to be changed and the position of the diamond wire needs to be adjusted to a new predetermined position, the auxiliary adjusting device is in the adjusting state, and at this time the relative position of the moving mechanism 12 on the guide rail mechanism 11 and the relative position between the rotating mechanism 13 and the moving mechanism 12 are adjusted, and the diamond wire is adjusted to the new predetermined position by the laser emitted by the calibration member 152 guiding the diamond wire connected to the main roller. The adjustment method is as follows:

[0034] The first guide mechanism 161 is abutted to the main roller and is tangent to the main roller.

[0035] The position of the calibration member 152 relative to the mounting member 151 is adjusted, so that the light emitted by the calibration member 152 extends in a predetermined direction.

[0036] The moving mechanism 12 moves along the guide rail mechanism 11, and / or the rotating mechanism 13 rotates relative to the moving mechanism 12, so that the diamond wire located in the guide groove 1621 coincides with the light emitted by the calibration member 152.

[0037] Specifically, the first guide mechanism 161 is installed on the rotating mechanism 13, and the rotating mechanism 13 is adjusted to rotate relative to the moving mechanism 12 and abut the one end of the first guide mechanism 161 away from the rotating mechanism 13 against the main roller.

[0038] The first adjusting mechanism 1511a is adjusted to make the laser emitted by the calibration piece 152 tangent to the main roller, and the second adjusting mechanism 1511b is adjusted to make the calibration piece 152 adjusted when the laser emitted by the calibration piece 152 is tangent to the outer side edge of the accommodating groove 1421.

[0039] As an alternative embodiment, since the installation position of the main roller is fixed, the calibration piece 152 can not be adjusted again after the initial adjustment is completed, and subsequent when the diamond wire deviates from the preset position, the position of the diamond wire is adjusted by using the moving mechanism 12 and the rotating mechanism 13.

[0040] The method for adjusting the position of the diamond wire by using the rotating mechanism 13 is: opening the calibration piece 152, adjusting the rotating mechanism 13 to rotate relative to the moving mechanism 12, and adjusting when the laser emitted by the calibration piece 152 is tangent to the main roller.

[0041] The method for adjusting the position of the diamond wire by using the moving mechanism 12 is: opening the calibration piece 152, rotating the handle part 1221 to make the moving mechanism 12 slide relative to the guide rail mechanism 11, and adjusting when the laser emitted by the calibration piece 152 is tangent to the diamond wire.

[0042] In the present application, the calibration method by laser positioning makes the position adjustment of the diamond wire have higher linearity and stronger accuracy; and the laser positioning also provides a reference datum for the position adjustment of the moving mechanism 12 and the rotating mechanism 13, expands the application range of the calibration mechanism 15 and further improves the accuracy of the auxiliary adjusting device 100; the calibration method by laser positioning also reduces the influence of the environment on the calibration accuracy, improves the reliability and convenience of the repeated use of the auxiliary adjusting device 100. At the same time, the setting method for adjusting the position of the calibration piece 152 by the first adjusting mechanism 1511a and the second adjusting mechanism 1511b avoids the adjustment error of the calibration piece 152 and guarantees the adjustment accuracy of the auxiliary adjusting device 100.

[0043] It should be understood that for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
