[0020] The present invention provides a spindle control mechanism for a horizontal CNC machine tool, which has the following beneficial effects:

[0021] 1. The spindle operating mechanism of the horizontal CNC machine tool, through the coordinated action of the bearings, fixing seats, bolts and warning components in the detection mechanism, can drive the swing plate and the shielding plate to swing when the cylindrical material is offset, so that the light of the first warning light or the second warning light is emitted, and the staff is prompted with different brightness, so that the staff can find the offset of the material in time, effectively avoid the problem of poor processing accuracy caused by material offset, and ensure the stability and accuracy of the processing process.

[0022] 2. The spindle operating mechanism of the horizontal CNC machine tool is equipped with a first warning light and a second warning light in the warning component, and the brightness of the second warning light is greater than that of the first warning light. When there is a small deviation, the first warning light is emitted to remind the staff, and when there is a large deviation, the second warning light is on to give a more obvious warning. This dual warning method allows the staff to judge the degree of material deviation more accurately according to the brightness of the light, so as to take corresponding measures in time to adjust the processing status and improve the processing accuracy and quality.

[0023] 3. The spindle control mechanism of the horizontal CNC machine tool uses the elastic extrusion of the spring to make the rotating wheel contact with the cylindrical material. During the normal rotation of the cylindrical material, the rotating wheel will rotate accordingly, driving the movable rod to move and causing the bell to make a small sound, reminding the staff that the machine tool is working normally. When the material offset rotation amplitude increases, the bell will swing sharply and produce a louder sound, realizing real-time monitoring of the processing status, ensuring that the staff is aware of the material processing status at any time, and further reducing the probability of processing accuracy problems caused by unstable material fixation.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] For example, see Figure 1-6 The present invention provides a technical solution: a spindle control mechanism for a horizontal CNC machine tool, comprising a control component 1, a control component 2 is fixedly connected to the outer wall of the control component 1, a spindle component 4 is movably connected to the outer wall of the control component 1, a chuck 3 is rotatably connected to the outer wall of the control component 1, a mounting hole 6 is opened on the outer wall of the control component 1 at the position of the chuck 3, and a detection mechanism 5 is fixedly connected to the outer wall of the control component 1 at the position of the mounting hole 6;

[0036] Combined with Figure 1 As shown, the chuck 3 is arranged on the operating component 1, and the control component 2 can control the start of each device, insert the circular material to be processed into the mounting hole 6 and then fix it on the chuck 3, and then the spindle component 4 is started to turn the cylindrical material;

[0037] The detection mechanism 5 includes:

[0038] Bearing 54, a cylindrical material is fixed inside the chuck 3, and the cylindrical material is also inserted into the bearing 54 and the mounting hole 6;

[0039] The fixed seat 51 and the bearing 54 are divided into an inner ring, an outer ring and a rotor, and the fixed seat 51 is fixedly connected to the inner ring of the bearing 54;

[0040] A bolt 52, the bolt 52 being threadedly connected to the interior of the fixing seat 51;

[0041] The warning component 55 is fixedly connected to the outer ring of the bearing 54 .

[0042] The fixing seat 51 is fixedly connected to the inner ring of the bearing 54 via a connecting rod 53, and the bolt 52 is in active contact with the cylindrical material;

[0043] Combined with Figure 2 and attached Figure 3 As shown, the cylindrical material is also inserted into the bearing 54, and then the bolt 52 is rotated to fix the cylindrical material. Therefore, when the chuck 3 drives the cylindrical material to rotate normally, the warning component 55 will not be driven to rotate. Then, when the cylindrical material deviates, the swing plate 552 will be driven to deviate, and then the swing plate 552 and the shielding plate 551 will swing. When the shielding plate 551 is normally hung down, the light emitted by the second warning light 554 and the first warning light 553 will be blocked. Then, a small swing of the shielding plate 551 will cause the first warning light 553 to leak out to prompt the staff. When the cylindrical material swings greatly, it will drive the shielding plate 551 to swing greatly. At this time, the light of the second warning light 554 will prompt the staff. The brightness of the second warning light 554 is greater than that of the first warning light 553, so the brightness will further prompt the staff.

[0044] The warning assembly 55 includes a swing plate 552 , which is fixedly connected to the outer ring of the bearing 54 .

[0045] The outer wall of the swing plate 552 is fixedly connected with a shielding plate 551 , the outer wall of the operating component 1 adjacent to the shielding plate 551 is fixedly connected with a second warning light 554 , and the outer wall of the second warning light 554 is fixedly connected with a first warning light 553 .

[0046] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0047] A placement groove 7 is provided inside the operating component 1 , and the placement groove 7 is communicated with the mounting hole 6 , and a prompt mechanism 8 is fixedly connected inside the placement groove 7 .

[0048] The prompt mechanism 8 includes a spring 82, which is fixedly connected to the inner wall of the placement groove 7. The outer wall of the spring 82 is fixedly connected to a movable rod 83, and the outer wall of the movable rod 83 is rotatably connected to a rotating wheel 85. The inner wall of the placement groove 7 is fixedly connected to a limiting ring 84, and the outer wall of the movable rod 83 is fixedly connected to a movable component 86.

[0049] A bracket 81 is fixedly connected between the spring 82 and the inner wall of the placement groove 7, and the rotating wheel 85 is in active contact with the cylindrical material.

[0050] The movable rod 83 is inserted into the limiting ring 84;

[0051] Combined with Figure 6 and attached Figure 7 As shown, the elastic length of the spring 82 is greater than the distance from the movable rod 83 to the cylindrical material, so the rotating wheel 85 is squeezed onto the cylindrical material under the elastic extrusion of the spring 82. A protrusion is set on the rotating wheel 85, so during the rotation of the cylindrical material, the rotating wheel 85 will be driven to rotate, and then the movable rod 83 will be driven to move, and then the bell 863 will be driven to move, causing it to make a small sound when shaking, prompting the staff that they are working normally, and then when the cylindrical material is offset, the increase in the rotation amplitude will drive the bell 863 to swing significantly, and then drive the bell 863 to produce a sound, thereby prompting the staff that the cylindrical material has shifted.

[0052] The movable component 86 includes a limiting hole 861, which is formed on the outer wall of the movable rod 83, and the limiting rod 862 is inserted into the inner wall of the limiting hole 861, and the outer wall of the limiting rod 862 is movably connected with a bell 863;

[0053] Combined with Figure 8 As shown, the diameter of the limiting hole 861 is larger than that of the limiting rod 862 , and balls are provided at both ends of the limiting rod 862 to prevent the limiting rod 862 from falling off the limiting hole 861 .

[0054] For example 3, please refer to Figure 1-8 , the present invention provides another technical solution:

[0055] In this embodiment, the outer wall of the rotating wheel 85 is smooth, so it will not shake when in contact with the cylindrical material, and will not cause the bell 863 to make a sound;

[0056] A spindle control mechanism for a horizontal CNC machine tool, comprising a control component 1, a control component 2 is fixedly connected to the outer wall of the control component 1, a spindle component 4 is movably connected to the outer wall of the control component 1, a chuck 3 is rotatably connected to the outer wall of the control component 1, a mounting hole 6 is opened on the outer wall of the control component 1 at the position of the chuck 3, and a detection mechanism 5 is fixedly connected to the outer wall of the control component 1 at the position of the mounting hole 6;

[0057] Combined with Figure 1 As shown, the chuck 3 is arranged on the operating component 1, and the control component 2 can control the start of each device, insert the circular material to be processed into the mounting hole 6 and then fix it on the chuck 3, and then the spindle component 4 is started to turn the cylindrical material;

[0058] The detection mechanism 5 includes:

[0059] Bearing 54, a cylindrical material is fixed inside the chuck 3, and the cylindrical material is also inserted into the bearing 54 and the mounting hole 6;

[0060] The fixed seat 51 and the bearing 54 are divided into an inner ring, an outer ring and a rotor, and the fixed seat 51 is fixedly connected to the inner ring of the bearing 54;

[0061] A bolt 52, the bolt 52 being threadedly connected to the interior of the fixing seat 51;

[0062] The warning component 55 is fixedly connected to the outer ring of the bearing 54 .

[0063] The fixing seat 51 is fixedly connected to the inner ring of the bearing 54 via a connecting rod 53, and the bolt 52 is in active contact with the cylindrical material;

[0064] Combined with Figure 2 and attached Figure 3 As shown, the cylindrical material is also inserted into the bearing 54, and then the bolt 52 is rotated to fix the cylindrical material. Therefore, when the chuck 3 drives the cylindrical material to rotate normally, the warning component 55 will not be driven to rotate. Then, when the cylindrical material deviates, the swing plate 552 will be driven to deviate, and then the swing plate 552 and the shielding plate 551 will swing. When the shielding plate 551 is normally hung down, the light emitted by the second warning light 554 and the first warning light 553 will be blocked. Then, a small swing of the shielding plate 551 will cause the first warning light 553 to leak out to prompt the staff. When the cylindrical material swings greatly, it will drive the shielding plate 551 to swing greatly. At this time, the light of the second warning light 554 will prompt the staff. The brightness of the second warning light 554 is greater than that of the first warning light 553, so the brightness will further prompt the staff.

[0065] The warning assembly 55 includes a swing plate 552 , which is fixedly connected to the outer ring of the bearing 54 .

[0066] The outer wall of the swing plate 552 is fixedly connected with a shielding plate 551 , the outer wall of the operating component 1 adjacent to the shielding plate 551 is fixedly connected with a second warning light 554 , and the outer wall of the second warning light 554 is fixedly connected with a first warning light 553 .

[0067] A placement groove 7 is provided inside the operating component 1 , and the placement groove 7 is communicated with the mounting hole 6 , and a prompt mechanism 8 is fixedly connected inside the placement groove 7 .

[0068] The prompt mechanism 8 includes a spring 82, which is fixedly connected to the inner wall of the placement groove 7. The outer wall of the spring 82 is fixedly connected to a movable rod 83, and the outer wall of the movable rod 83 is rotatably connected to a rotating wheel 85. The inner wall of the placement groove 7 is fixedly connected to a limiting ring 84, and the outer wall of the movable rod 83 is fixedly connected to a movable component 86.

[0069] A bracket 81 is fixedly connected between the spring 82 and the inner wall of the placement groove 7, and the rotating wheel 85 is in active contact with the cylindrical material.

[0070] The movable rod 83 is inserted into the limiting ring 84;

[0071] Combined with Figure 6 and attached Figure 7 As shown, the elastic length of the spring 82 is greater than the distance from the movable rod 83 to the cylindrical material, so the rotating wheel 85 is squeezed onto the cylindrical material under the elastic extrusion of the spring 82, and the rotating wheel 85 is driven to rotate during the rotation of the cylindrical material. When the cylindrical material is offset, the increase in the rotation amplitude will drive the bell 863 to swing significantly, and then drive the bell 863 to produce a sound, thereby reminding the staff that the cylindrical material has been offset.

[0072] The movable component 86 includes a limiting hole 861, which is formed on the outer wall of the movable rod 83, and the limiting rod 862 is inserted into the inner wall of the limiting hole 861, and the outer wall of the limiting rod 862 is movably connected with a bell 863;

[0073] Combined with Figure 8 As shown, the diameter of the limiting hole 861 is larger than that of the limiting rod 862 , and balls are provided at both ends of the limiting rod 862 to prevent the limiting rod 862 from falling off the limiting hole 861 .
