Description

Technical Field

[0001] The utility model relates to the technical field of vertical milling machines, in particular to a tightening and fixing device for a motor of a vertical milling machine. Background Art

[0002] Compared with horizontal milling machines, the main difference between vertical milling machines and horizontal milling machines is that the spindle is arranged vertically. In addition to the different spindle arrangements, the worktable can be raised and lowered. The milling cutter used in vertical milling machines is relatively flexible and has a wider range of applications. Vertical milling cutters, machine clamp cutter discs, drill bits, etc. can be used. Keyways, planes, boring holes, etc. can be milled. Horizontal milling machines can also use the above tools, but they are not as convenient as vertical milling machines. The main thing is that the hanger can be used to enhance the strength of the tool (mainly three-face milling cutters, sheet milling cutters, etc.). Grooves, planes, cutting, etc. can be milled. Horizontal milling machines generally have vertical milling heads. Although the functions and rigidity of this vertical milling head are not as powerful as those of vertical milling machines, they are sufficient to cope with vertical milling processing. This makes the overall function of horizontal milling machines more powerful than vertical milling machines. Vertical milling machines do not have this feature and cannot process workpieces suitable for horizontal milling. The productivity is higher than that of horizontal milling machines.

[0003] The motor on the existing vertical milling machine can convert electrical energy into mechanical energy, so that the cutting tool of the milling machine rotates at high speed, thereby achieving the effect of cutting the surface of the workpiece. Generally, a belt structure is installed in the middle, but the existing motor structure cannot automatically adjust the tightness, nor can it conveniently detect the tightness of the belt. It requires manual testing again and again, which is very cumbersome. Secondly, when the belt is installed on the gear, it may fall off after working for a long time, but it cannot be discovered in the first time, which will delay production efficiency. Therefore, a vertical milling machine motor tension fixing device is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing motor structure cannot automatically adjust the tightness, nor can it conveniently detect the tightness of the belt, and requires manual testing again and again, which is very cumbersome. Secondly, when the belt is installed on the gear, it may fall off after working for a long time, but it cannot be discovered in the first time, which will delay production efficiency. A vertical milling machine motor tension fixing device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vertical milling machine motor tensioning and fixing device, including a machine table, a drive controller is installed on one side of the front and back of the machine table, one end of the drive controller is electrically connected to the drive motor, one end of the drive motor is transmission-connected to the drive shaft, the external thread of the drive shaft is connected to a movable slide, the movable slides are slidably connected to the side of the machine table, and the top of the movable slide is connected to a sliding adjustment plate.

[0006] Preferably, a slide bar is provided on the top of the machine platform, a slide adjustment plate is slidably connected to the top of the slide bar, and a welding plate is welded to one side of the top of the slide adjustment plate.

[0007] Preferably, a derailment detection end is installed on one side of the front face of the welding plate, the front face of the derailment detection end is electrically connected to a derailment detection probe, embedded frames are installed on the top and bottom of one side of the front face of the welding plate, a lifting drive control component is installed on the top of the embedded frame, the bottom end of the lifting drive control component is transmission-connected with a coupling, the external thread of the coupling is connected with a slider, and the slider is slidably connected to the inside of the embedded frame.

[0008] Preferably, an adjustment hook is installed on the front of the slider, the components in the top and bottom frames on the front of the welding plate are the same, but in opposite directions, and one side of the derailment detection end is electrically connected to the lifting drive control component.

[0009] Preferably, a motor body is installed on one side of the top of the machine platform, a wheel disc is installed in the motor body, and a belt is clamped in the middle of the wheel disc.

[0010] Preferably, a gear set is installed in the middle of the top end of the sliding adjustment plate, the other side of the belt is clamped on the surface of the gear set, the surface of the gear set is provided with an annular groove, and the belt is clamped in the annular groove.

[0011] Preferably, tension detectors are installed on both sides of the top of the sliding adjustment plate close to the gear group, the front of the tension detector is electrically connected to a Bluetooth transmitter, one end of the tension detector is connected to a tension arm, and a hook is installed at one end of the tension arm.

[0012] Beneficial Effects

[0013] In the utility model, when the belt position is above the annular groove, it will be determined that the belt is deflected upward, and the opposite is true below. When the derailment detection end verifies and calculates that the belt is deflected upward, it will transmit a signal to the lifting drive control component at the top, and then the lifting drive control component at the top will control the motor at the bottom to start, and indirectly drive the slider to slide down through the motor at the bottom. During the sliding process of the slider, the front adjustment hook will press down the belt, so that the belt re-enters the annular groove, which solves the problem that the belt may fall off when it is installed on the gear and works for a long time, but it cannot be discovered in the first time, which will delay production efficiency.

[0014] In the utility model, the tension detector detects the tension of the belt through the tension arm and the hook, and the tension detector transmits the detected tension value to the mobile terminal through the Bluetooth transmitter. The operator can observe the change of tension on the mobile device. When the required tension is reached, the movement of the sliding adjustment plate is stopped, so that the belt can be adjusted to the optimal tightness, which solves the problem that the existing motor structure cannot automatically adjust the tightness, nor can it conveniently detect the tightness of the belt, and requires manual testing again and again, which is very cumbersome.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0024] Reference Figure 1-4A vertical milling machine motor tightening and fixing device includes a machine table 1, a driving controller 4 is installed on one side of the front and back of the machine table 1, one end of the driving controller 4 is electrically connected to a driving motor 5, one end of the driving motor 5 is transmission-connected to a driving shaft 6, the external thread of the driving shaft 6 is connected to a moving slide 7, the moving slide 7 is slidably connected to the side of the machine table 1, and the top of the moving slide 7 is connected to a sliding adjustment plate 2.

[0025] In this device, the tightness of the belt is adjusted mainly by adjusting the distance between the sliding adjustment plate 2 and the motor body 8. The closer the distance, the lower the tightness. The movement of the movable slide 7 is mainly dependent on the driving motor 5, and the driving motor 5 is mainly controlled by the driving controller 4. The driving motor 5 will control the driving shaft 6 to rotate clockwise and counterclockwise, and the movable slide 7 will slide back and forth with the rotation. When sliding, the movable slide 7 will drive the top sliding adjustment plate 2 to slide on the sliding rod 3. The sliding rod 3 here is similar to the slide rail of the sliding adjustment plate 2.

[0026] A slide bar 3 is provided on the top of the machine platform 1 , a slide adjustment plate 2 is slidably connected to the top of the slide bar 3 , and a welding plate 11 is welded to one side of the top of the slide adjustment plate 2 .

[0027] A derailment detection end 18 is installed on one side of the front of the welding plate 11, and the front of the derailment detection end 18 is electrically connected to a derailment detection probe 17. An embedding frame 20 is installed on the top and bottom of one side of the front of the welding plate 11, and a lifting drive control component 19 is installed on the top of the embedding frame 20. The bottom end of the lifting drive control component 19 is transmission-connected with a connecting shaft 21, and the external thread of the connecting shaft 21 is connected to a slider 22, and the slider 22 is slidably connected to the inside of the embedding frame 20.

[0028] The front of the slider 22 is equipped with an adjustment hook 23. The components in the top and bottom bezels 20 of the front of the welding plate 11 are the same, but in opposite directions. One side of the derailment detection end 18 is electrically connected to the lifting drive control component 19.

[0029] The structure on the welding plate 11 in the sliding adjustment plate 2 is used to detect whether the belt 10 is out of the annular groove at the outer center position of the gear set 12. The derailment detection probe 17 on the front of the derailment detection end 18 is similar to a small belt slip detector, which is specially used to detect whether the belt is slipping. At the same time, an image acquisition element will be installed in the derailment detection probe 17 to collect the image of the belt position outside the gear. After the collection, the image will be transmitted to the derailment detection end 18. A small computer is installed in the derailment detection end 18 to calculate the position of the belt. The small computer will use the annular groove outside the gear as a reference when calculating. When the belt position is above the annular groove, it will be determined that the belt is offset upwards, and the opposite is true below. When the derailment detection probe 17 is installed, the image acquisition element will be installed in the derailment detection probe 17 to collect the image of the belt position outside the gear. After the collection, the image will be transmitted to the derailment detection end 18. A small computer will be installed in the derailment detection end 18 to calculate the position of the belt. The small computer will use the annular groove outside the gear as a reference when calculating. When the belt position is above the annular groove, it will be determined that the belt is offset upwards, and the opposite is true below. When the measuring end 18 checks and calculates that the belt is deflected upward, it will transmit a signal to the lifting drive control component 19 at the top, and then the lifting drive control component 19 at the top will control the start of the motor at the bottom, and indirectly drive the slider 22 to slide down through the motor at the bottom. During the sliding process of the slider 22, the front adjustment hook 23 will press down the belt 10, so that the belt 10 re-enters the annular groove. After the work is completed, the slider 22 will return to its initial position. It should be noted that the structure in the bottom embedded frame 20 is mainly used to hook the downward-deflected belt 10 into the annular groove. The working principles are the same. At the same time, the upper and lower adjustment hooks 23 are arc-shaped, but in opposite directions. The specific circuit design of the small computer needs to be based on actual conditions. Specific embodiment 2:

[0031] Reference Figure 1-4 A motor body 8 is installed on one side of the top of the machine 1, a wheel disc 9 is installed in the motor body 8, and a belt 10 is clamped in the middle of the wheel disc 9.

[0032] A gear set 12 is installed in the middle of the top of the sliding adjustment plate 2, and the other side of the belt 10 is clamped on the surface of the gear set 12. The surface of the gear set 12 is provided with an annular groove, and the belt 10 is clamped in the annular groove.

[0033] Tension detectors 13 are installed on both sides of the top of the sliding adjustment plate 2 near the gear set 12. The front of the tension detector 13 is electrically connected to a Bluetooth transmitter 14. One end of the tension detector 13 is connected to a tension arm 15, and one end of the tension arm 15 is installed with a hook 16.

[0034] The tension detectors 13 on both sides of the top of the sliding adjustment plate 2 are used to detect the tension of the belt 10 and indirectly detect the tightness of the belt 10. The higher the tension value, the higher the tightness. The tension detector 13 here is an electronic storage type. When working, the hook 16 is hooked to the position where the belt 10 and the gear set 12 are connected, and then the sliding adjustment plate 2 is controlled to move. As the sliding adjustment plate 2 moves, the tension detector 13 will detect the tension of the belt 10 through the tension arm 15 and the hook 16. The tension detector 13 will transmit the detected tension value to the mobile terminal through the Bluetooth transmitter 14. The operator can observe the change of tension on the mobile device. When the required tension is reached, the movement of the sliding adjustment plate 2 is stopped, so that the belt 10 can be adjusted to the optimal tightness. The principle of the tension detector 13 here is mainly to use the principle of elastic deformation. By stretching the sample, the tensile strength, yield strength, elongation and other mechanical performance indicators of the sample are measured. Its basic principle is to apply a certain tensile load to the sample to make the sample tensile deformation, so as to obtain the corresponding mechanical performance indicators.

[0035] In summary:

[0036] 1. When the belt position is above the annular groove, it will be determined that the belt is deflected upward. The opposite is true below. When the derailment detection end 18 verifies and calculates that the belt is deflected upward, it will transmit a signal to the top lifting drive control component 19, and then the top lifting drive control component 19 will control the bottom motor to start, and indirectly drive the slider 22 to slide down through the bottom motor. During the sliding process of the slider 22, the front adjustment hook 23 will press down the belt 10, so that the belt 10 re-enters the annular groove.

[0037] 2. The tension detector 13 will detect the tension of the belt 10 through the tension arm 15 and the hook 16. The tension detector 13 will transmit the detected tension value to the mobile terminal through the Bluetooth transmitter 14. The operator can observe the change of tension on the mobile device. When the required tension is reached, the movement of the sliding adjustment plate 2 is stopped, so that the belt 10 can be adjusted to the optimal tightness.
