Description

Technical Field

[0001] This invention belongs to the technical field of profile processing equipment, specifically relating to a CNC corner code guiding mechanism and its working method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In the field of profile assembly, using corner brackets to connect and fix profiles to adjacent profiles is a common method. In traditional profile assembly, because the corner brackets and the inner cavity of the profile have a clearance fit, after the corner brackets are placed at both ends of the inner cavity of the fixed profile, their planes inevitably have an inclination in the horizontal direction, making it difficult to align with the horizontal plane of the corresponding inner cavity of the adjacent profile. Existing technology publication number CN218347253U provides a guide corner bracket that achieves posture correction of the corner bracket through guide screw holes. This guide corner bracket has a special structure. However, for ordinary corner brackets, existing technology does not consider a mechanism for automatically correcting the posture of the angle steel pieces. This means that during actual profile assembly, tools are needed to semi-automatically adjust the position and angle of the angle steel pieces. The operation process is not only cumbersome and inefficient, but also makes it difficult to guarantee the accuracy and consistency of the assembly. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a CNC corner code guiding mechanism and its working method. By controlling the support rod mechanism, the upper plane of the guide block coincides with the lower plane of the inner cavity of two adjacent profiles, ensuring that adjacent profiles can be smoothly inserted into the corner codes at both ends of the fixed profile. This achieves high-precision correction of the corner codes and automatic splicing of the profiles, improving assembly efficiency and consistency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, the present invention provides a CNC corner code guiding mechanism, comprising: a vertical plate base; a first vertical guide rail pair is provided on one side of the vertical plate base, and the vertical plate base is connected to a vertical slide plate through the first vertical guide rail pair; the vertical slide plate is connected to one side of a horizontal slide plate through a horizontal guide rail pair; the vertical slide plate is driven by a lifting cylinder provided on the vertical plate base, and the horizontal slide plate is driven by a translation cylinder provided on the vertical slide plate, wherein both the translation cylinder and the lifting cylinder are connected to a compressed air source, and the compressed air source is connected to a control device;

[0007] A second vertical guide rail pair is provided on the other side of the horizontal slide plate. A first support rod mechanism and a second support rod mechanism are arranged on the second vertical guide rail pair. The first support rod mechanism is driven by a first servo transmission mechanism provided on the top of the horizontal slide plate, and the second support rod mechanism is driven by a second servo transmission mechanism provided on the top of the horizontal slide plate. Both the first servo transmission mechanism and the second servo transmission mechanism are connected to a control device.

[0008] Both the first and second support rod mechanisms include a slide block, a support rod, and a guide block. The slide block is fixedly mounted on the slider of the second vertical guide rail pair on one side. The support rod is provided at one end of the slide block. The support rod is provided with a scale and a guide block. The guide block is used to guide the angle of the angle steel in the profile and to guide the assembly of adjacent profiles.

[0009] Furthermore, the upper part of the upright plate base is provided with a U-shaped groove, so that the telescopic rod of the lifting cylinder can move in and out of the U-shaped groove; the telescopic rod of the lifting cylinder is hinged to the vertical slide plate through a connector, and the vertical slide plate is connected to the movable slider of the first vertical guide rail pair through fasteners.

[0010] Furthermore, the top of the upright base is also provided with an adjustable limiting component, which can move up and down to adjust the travel of the vertical slide; the adjustable limiting component is provided with a pressure sensor, which is used to control the start and stop of the lifting cylinder.

[0011] Furthermore, the first servo transmission mechanism includes a first servo motor and a first lead screw. The first servo motor is fixedly mounted on the horizontal slide plate via a servo mechanism bracket. The end of the first lead screw near the first servo motor is fixedly mounted on the horizontal slide plate via a bearing. The slider of the first lead screw is connected to the slide of the first support mechanism. The slider of the first lead screw and the support rod of the first support mechanism are fixed at the same end of the slide of the first support mechanism. The first lead screw is driven to rotate by the first servo motor, thereby driving the slide of the first support mechanism to move up and down.

[0012] Furthermore, the second servo transmission mechanism includes a second servo motor and a second lead screw. The second servo motor is fixedly mounted on the horizontal slide plate via a servo mechanism bracket. One end of the second lead screw near the second servo motor is fixedly mounted on the horizontal slide plate via a bearing. The slider of the second lead screw is connected to the slide of the second support mechanism. The slider of the second lead screw and the support rod of the second support mechanism are respectively fixed to both ends of the slide of the second support mechanism. The second lead screw is driven to rotate by the second servo motor, thereby driving the slide of the second support mechanism to move up and down.

[0013] Furthermore, the translation cylinder is fixedly mounted on the edge of the vertical slide plate via a cylinder bracket, and the cylinder bracket and the vertical slide plate are fixedly connected by a connector.

[0014] Furthermore, the control device is equipped with a control panel for setting parameters and controlling the extension and retraction speed and clamping force of the translation cylinder and the lifting cylinder.

[0015] Furthermore, both the first servo motor and the second servo motor are connected to the control device. The control device controls the rotation speed and number of rotations of the first servo motor and the second servo motor respectively, thereby controlling the movement distance of the slider of the corresponding lead screw.

[0016] Furthermore, the first vertical guide rail pair, the second vertical guide rail pair, and the horizontal guide rail pair are all provided with lubricating oil filling ports, which are used to add lubricating oil to prevent wear when the guide rail pairs move frequently.

[0017] Secondly, the present invention also provides a method for operating a CNC corner code guiding mechanism, comprising the following steps:

[0018] S1. Adjust the guide block according to the size of different profiles, and make adjustments with reference to the scale on the support rod;

[0019] S2. After the angle steel sheet is inserted into the cavity of the fixed profile, the translation cylinder and the lifting cylinder are started under the control of the control device, and the first support rod mechanism and the second support rod mechanism are sent to the designated position.

[0020] S3. After the first support rod mechanism and the second support rod mechanism reach the designated position, the first servo motor and the second servo motor are started under the control of the control device, and drive the support rod to drive the guide block to correct the orientation of the angle steel, so that the angle steel can be easily inserted into the adjacent profile when assembling the fixed profile and the adjacent profile.

[0021] Compared with the prior art, the advantages and positive effects of this invention are:

[0022] This invention adjusts the guide blocks of the first and second support rod mechanisms to ensure that the upper plane of the guide block coincides with the lower plane of the inner cavity of the fixed profile and the lower plane of the inner cavity of the adjacent profile, thus ensuring that the adjacent profiles can be smoothly inserted into the corner brackets at both ends of the fixed profile. The first and second servo motors are connected to the control device, which can precisely control the rotation speed and number of rotations, thereby precisely controlling the movement distance of the corresponding lead screw slider, achieving precise adjustment of the height of the support rod mechanism to meet the assembly requirements of different profiles. At the same time, the translation cylinder and the lifting cylinder are connected to the compressed air source and the control device, which can control their extension speed and clamping force, further improving the accuracy and stability of the equipment operation, realizing high-precision corner bracket correction and automatic profile splicing, and greatly improving assembly efficiency.

[0023] The adjustable limiting component at the top of the vertical plate base of this invention can adjust the travel of the vertical slide plate, and the pressure sensor in the limiting component can control the start and stop of the lifting cylinder, effectively preventing the vertical slide plate from deforming and failing due to continuous contraction of the lifting cylinder, thus ensuring the safe and stable operation of the equipment. Lubricating oil filling ports are provided on the first vertical guide rail pair, the second vertical guide rail pair, and the horizontal guide rail pair, which can be lubricated regularly, effectively preventing wear when the guide rail pairs move frequently, extending the overall service life of the equipment, and reducing maintenance costs.

[0031] Example 1

[0032] This embodiment discloses a CNC corner code guiding mechanism, such as Figures 1-3 As shown, it includes: a vertical plate base 1; a first vertical guide rail pair 3 is provided on one side of the vertical plate base 1, and the vertical plate base 1 is connected to a vertical slide plate 2 through the first vertical guide rail pair 3; the vertical slide plate 2 is connected to one side of a horizontal slide plate 5 through a horizontal guide rail pair 7; the vertical slide plate 2 is driven by a lifting cylinder 4 provided on the vertical plate base 1, and the horizontal slide plate 5 is driven by a translation cylinder 10 provided on the vertical slide plate 2;

[0033] On the other side of the horizontal slide plate 5, a second vertical guide rail pair 15 is provided. A first support rod mechanism 11 and a second support rod mechanism 12 are arranged on the second vertical guide rail pair 15. The first support rod mechanism 11 is driven by a first servo transmission mechanism provided on the top of the horizontal slide plate 5, and the second support rod mechanism 12 is driven by a second servo transmission mechanism provided on the top of the horizontal slide plate 5.

[0034] Both the first support rod mechanism 11 and the second support rod mechanism 12 include a slide block, a support rod 14, and a guide block 13. One side of the slide block is fixedly mounted on the slider of the second vertical guide rail pair 15. One end of the slide block is provided with the support rod 14, which is equipped with a scale and a guide block 13. The guide block 13 is used to guide the angle of the angle steel within the profile, thus guiding the assembly of adjacent profiles. Specifically, since the height and thickness of the angle steel have a certain gap with the inner cavity of the profile, their fit is a clearance fit. When the angle steel is placed at both ends of the inner cavity of the fixed profile, the upper or lower plane of each angle steel will definitely have a certain inclination to the horizontal direction, making it impossible for it to be aligned with adjacent profiles. The horizontal planes of the inner cavities of the corresponding profiles are aligned. To ensure that each corner bracket is smoothly inserted into the inner cavity of the adjacent profile, the height of each support rod 14 can be adjusted so that the upper plane of the guide block 13 of the first support rod mechanism 11 and the second support rod mechanism 12 is aligned with the lower plane of the inner cavity of the fixed profile, that is, coplanar with the lower plane of the corner brackets at both ends of the fixed profile. The upper plane of the guide block 13 of the first support rod mechanism 11 and the second support rod mechanism 12 is aligned with the lower plane of the inner cavity of the adjacent profile, that is, the lower plane of the adjacent profile is coplanar with the lower plane of the corner brackets at both ends of the fixed profile, thereby enabling the adjacent profile to be smoothly inserted into the corner brackets at both ends of the fixed profile, realizing the splicing between the fixed profile and the adjacent profile.

[0035] The upper part of the upright base 1 is provided with a U-shaped groove, which allows the telescopic rod of the lifting cylinder 4 to extend and retract within the U-shaped groove; the telescopic rod of the lifting cylinder 4 is hinged to the vertical slide plate 2 via a connector, and the vertical slide plate 2 is connected to the movable slider of the first vertical guide rail pair 3 via fasteners.

[0036] The top of the vertical plate base 1 is also provided with an adjustable limiting component, which can move up and down to adjust the travel of the vertical slide plate 2; the adjustable limiting component is provided with a pressure sensor, which is used to control the start and stop of the lifting cylinder 4, and can effectively prevent the vertical slide plate 2 from deforming and failing due to the continuous contraction of the lifting cylinder 4.

[0037] The first servo transmission mechanism includes a first servo motor 6 and a first lead screw 16. The first servo motor 6 is fixedly mounted on the horizontal slide plate 5 via a servo mechanism bracket 9. The end of the first lead screw 16 near the first servo motor 6 is fixedly mounted on the horizontal slide plate 5 via a bearing. The slider of the first lead screw 16 is connected to the slide of the first support rod mechanism 11. The slider of the first lead screw 16 and the support rod 14 of the first support rod mechanism 11 are fixed at the same end of the slide of the first support rod mechanism 11. The first lead screw 16 is driven to rotate by the first servo motor 6, thereby driving the slide of the first support rod mechanism 11 to move up and down.

[0038] The second servo transmission mechanism includes a second servo motor 8 and a second lead screw 17. The second servo motor 8 is fixedly mounted on the horizontal slide plate 5 via a servo mechanism bracket 9. One end of the second lead screw 17 near the second servo motor 8 is fixedly mounted on the horizontal slide plate 5 via a bearing. The slider of the second lead screw 17 is connected to the slide of the second support mechanism 12. The slider of the second lead screw 17 and the support rod 14 of the second support mechanism 12 are respectively fixed at both ends of the slide of the second support mechanism 12. The second lead screw 17 is driven to rotate by the second servo motor 8, thereby driving the slide of the second support mechanism 12 to move up and down.

[0039] The translation cylinder 10 is fixedly mounted on the edge of the vertical slide plate 2 by a cylinder bracket. The cylinder bracket and the vertical slide plate 2 are fixedly connected by a connector. The connector can be a hexagonal countersunk bolt, which can both remove the cylinder bracket and prevent the connector from obstructing other components.

[0040] Both the translation cylinder 10 and the lifting cylinder 4 are connected to a compressed air source, which is connected to a control device. The control device controls the extension and retraction speed and clamping force of the translation cylinder 10 and the lifting cylinder 4, respectively.

[0041] The first servo motor 6 and the second servo motor 8 are both connected to the control device. The control device controls the rotation speed and number of rotations of the first servo motor 6 and the second servo motor 8 respectively, thereby controlling the movement distance of the slider of the corresponding lead screw.

[0042] The first vertical guide rail pair 3, the second vertical guide rail pair 15, and the horizontal guide rail pair 7 are all provided with lubricating oil filling ports, which are used to add lubricating oil to prevent wear when the guide rail pairs move frequently.

[0043] Example 2

[0044] This embodiment also provides a working method for a CNC corner code guiding mechanism, including the following steps:

[0045] S1. Adjust the guide block 13 according to the size of different profiles, and make adjustments with reference to the scale on the support rod 14;

[0046] S2. After the angle steel sheet is inserted into the cavity of the fixed profile, the translation cylinder 10 and the lifting cylinder 4 are started under the control of the control device, and the first support rod mechanism 11 and the second support rod mechanism 12 are sent to the designated position.

[0047] S3. After the first support rod mechanism 11 and the second support rod mechanism 12 reach the designated position, the first servo motor 6 and the second servo motor 8 are started under the control of the control device, and drive the support rod 14 to drive the guide block 13 to correct the orientation of the angle steel. This facilitates the insertion of the angle steel into the adjacent profile during the assembly of the fixed profile and the adjacent profile. Specifically, by adjusting the height of each support rod 14, the upper plane of the guide block 13 of the first support rod mechanism 11 and the second support rod mechanism 12 coincides with the lower plane of the inner cavity of the fixed profile, that is, it is coplanar with the lower plane of the corner brackets at both ends of the fixed profile. The upper plane of the guide block 13 of the first support rod mechanism 11 and the second support rod mechanism 12 coincides with the corresponding lower plane of the inner cavity of the adjacent profile, that is, the lower plane of the adjacent profile is coplanar with the lower plane of the corner brackets at both ends of the fixed profile. This enables the adjacent profile to be smoothly inserted into the corner brackets at both ends of the fixed profile, realizing the splicing between the fixed profile and the adjacent profile.

[0048] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
