Description

Technical Field

[0001] This invention belongs to the field of metalworking machine tool technology, specifically a horizontal, dual-spindle, dual-disc five-axis machining center. Background Technology

[0002] A five-axis machining center is a high-precision CNC machining equipment that has the function of linkage control of five coordinate axes and can perform multi-face machining on workpieces with complex curved surfaces and irregular structures in one go. Compared with traditional machining equipment, it has stronger adaptability to machining complex workpieces and higher machining accuracy.

[0003] In most existing five-axis machining centers, only a single spindle and a single workpiece are configured. During the machining process, only a single workpiece can be processed. Before and after machining, the loading and unloading of the workpiece will cause a long waiting time for the five-axis machining center, thus making the working efficiency of the five-axis machining center low. To address this, related technologies improve the single-axis single-workpiece machining center by adding a spindle and a table, thereby improving the machining efficiency of the machining center and making it suitable for the production and processing of batch precision parts.

[0004] However, in practical applications, it has been found that since the core value of a dual-spindle, dual-table five-axis machining center lies in doubling efficiency without doubling the footprint, it occupies a smaller area and has less internal space compared to a conventional five-axis machining center. Furthermore, when the two spindles are machining simultaneously, the chip generation efficiency is doubled. Also, due to the different stages of actual machining, the chip removal volume varies, resulting in significant variations in the chip removal volume within the machining center. When the chip removal system is always operating at high efficiency, it will cause the chip removal system to idle and waste energy when the chip removal volume is small. On the other hand, if the chip removal efficiency is insufficient, chip accumulation will occur during the process of removing a large amount of chips.

[0005] In view of this, the present invention proposes a horizontal dual-spindle dual-disc five-axis machining center to solve the above-mentioned technical problems. Summary of the Invention

The sliding roller supports the chip conveyor belt upwards, and the weight sensing column is electrically connected to the electric support column.

[0009] Preferably, multiple weight sensing columns are provided, and the multiple weight sensing columns are arranged at equal intervals.

[0010] Preferably, a chip discharge port is provided on one side of the machine tool body, a waste chip box is installed outside the chip discharge port, the chip discharge belt extends through the chip discharge port to the top of the waste chip box, a hinge rod is rotatably installed in the chip discharge groove, one end of the mounting bracket is fixedly installed on the hinge rod, and the end of the mounting bracket away from the hinge rod is located above the sensing column.

[0011] Preferably, the mounting bracket is equipped with a connecting rod above the waste bin, and a cleaning brush is mounted on the connecting rod, with the cleaning brush in contact with the bottom surface of the waste conveyor belt.

[0013] Preferably, the cleaning brush consists of an elastic frame and a brush body. The elastic frame is made of elastic material, and the elastic frame has uniformly distributed material drop grooves along the movement direction of the chip conveyor belt. The brush body is fixedly installed on the elastic frame, and the brush body and the material drop grooves are arranged at intervals.

[0014] Preferably, an adsorption block is fixedly installed on the elastic frame, and an adsorption groove is provided on the mounting frame, with the adsorption block and the adsorption groove being magnetically adsorbed together.

[0015] Preferably, a one-way slow-release component is fixedly installed at the connection point between the hydraulic push rod and the series pipe.

[0017] The beneficial effects of this invention are as follows: 1. The horizontal dual-spindle dual-disc five-axis machining center of the present invention, by setting a variable speed chip removal mechanism, can detect the chip production rate in real time during actual processing and production, and adjust the power of the drive motor in real time according to the chip production rate, thereby linking the chip removal efficiency with the chip production efficiency. On the one hand, it can reduce the energy consumption of the equipment when chip production is low, and on the other hand, it can accelerate the chip removal efficiency when chip production is high, reducing the probability of chip accumulation and blockage. Thus, the improved horizontal dual-spindle dual-disc five-axis machining center of the present invention is more practical.

[0018] 2. The horizontal dual-spindle dual-disc five-axis machining center of the present invention uses a hydraulic push rod to extend and push the connecting rod to deflect and pull the tension spring. During this process, as the end of the connecting rod gradually moves away from the mounting frame, one end of the elastic frame is pulled, causing the elastic frame, brush body, and adsorption block to detach from the chip removal belt and adsorption tank one by one in sequence. At this time, the effective range of the cleaning brush and the chip removal belt gradually decreases, thereby gradually reducing the resistance of the cleaning brush to the operation of the chip removal belt and reducing the load on the drive motor. Conversely, when the amount of chip removal decreases, the operating speed of the chip removal belt slows down. At this time, under the reset action of the tension spring, the connecting rod and the cleaning brush gradually reset, thereby gradually increasing the effective area of ​​the cleaning brush on the chip removal belt and enhancing the cleaning effect on the chip removal belt.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 8 As shown, the horizontal dual-spindle dual-disc five-axis machining center of the present invention includes a machine tool body 1 and a five-axis machining system 11 installed in the machine tool body 1. In this invention, the five-axis machining system 11 is a dual-spindle dual-disc five-axis machining system 11 commonly used in conventional technology. As a technology well known to those skilled in the art, it will not be described in detail here. It also includes a variable speed chip removal mechanism, which is installed inside the machine tool body 1 and adjusts the speed according to the amount of chips removed. The variable speed chip removal mechanism includes a blowing nozzle, a mounting bracket 22, a chip removal belt 23, a drive motor 24, and a sensing column; The purge nozzle is installed on the five-axis machining system 11. The purge nozzle is used to spray fluid to the machining position. The purge nozzle is connected to an external fluid pump through a pipeline. The machine tool body 1 has a chip removal groove 12, a mounting frame 22 is installed in the chip removal groove 12, and a chip removal belt 23 is installed on the mounting frame 22. The chip removal belt 23 is used to transport chips. The drive motor 24 is mounted on the mounting bracket 22, and the output end of the drive motor 24 is used to drive the chip conveyor belt 23 to rotate. The chip removal groove 12 is equipped with a sensing column, and the mounting bracket 22 is installed on the top of the sensing column. The sensing column is an elastic telescopic structure. The sensing column is electrically connected to the drive motor 24 through a pre-set program. The higher the degree of compression of the sensing column, the greater the power of the drive motor 24.

[0023] In order to adjust the chip removal effect according to the actual working conditions when operating a horizontal twin-spindle twin-disc five-axis machining center, a variable speed chip removal mechanism is set in this invention. By sensing the weight change of the accumulated chips in real time during the working process, the chip removal efficiency is adjusted. When the chip production is slow, the machine operates at low speed to reduce the energy consumption of the equipment. When the chip production is fast, the machine operates at high speed to improve the chip removal effect, thereby realizing intelligent adjustment of the chip removal effect.

[0024] Specifically, during actual processing, the dual-spindle, dual-disc operation mode results in significant variations in chip removal volume due to changes in processing steps and stages. The generated chips are blown into the chip removal trough 12 by the fluid from the blow nozzles, which are continuously supplied with fluid by a fluid pump. In this invention, "fluid" refers to compressed air or coolant; the specific type used depends on the actual processing technology. As chip production efficiency changes, the total amount of chips falling onto the chip removal belt 23 per unit time varies. In this invention, the chip removal belt 23 is mounted on a mounting frame 22, which is sensed by... Because the column is supported, changes in weight alter the pressure on the sensing column. Under the control of a pre-set program, the power of the drive motor 24 is adjusted in real time according to the weight changes, thereby changing the speed at which the drive motor 24 drives the chip conveyor belt 23. When the chip production rate increases, the chip conveyor belt 23 operates faster, reducing the thickness of the chips that subsequently fall onto the chip conveyor belt 23, thus facilitating the discharge of chips to the outside. Conversely, when the chip production rate decreases, the power of the drive motor 24 is reduced synchronously, thereby reducing the total energy consumption for chip removal, which aligns with the energy-saving and environmentally friendly production concept.

[0025] This invention, by setting up a variable speed chip removal mechanism, detects the chip generation rate in real time during actual processing and production, and adjusts the power of the drive motor 24 in real time according to the chip generation rate. This links chip removal efficiency with chip generation efficiency, reducing energy consumption of the equipment at low chip generation speed and accelerating chip removal efficiency at high chip generation speed, thus reducing the probability of chip accumulation and blockage. This makes the improved horizontal dual-spindle dual-disc five-axis machining center of this invention more practical.

[0026] In a preferred embodiment of the present invention, the sensing column is composed of an electric support column 25 and a weight sensing column 26; The electric support column 25 is fixedly installed at the bottom of the chip discharge groove 12, and the electric support column 25 supports the mounting bracket 22; The weight sensing column 26 is mounted on the mounting bracket 22. A sliding roller 27 is rotatably mounted on the top of the weight sensing column 26. The sliding roller 27 supports the chip conveyor belt 23 upward. The weight sensing column 26 is electrically connected to the electric support column 25.

[0027] Multiple weight sensing columns 26 are provided and arranged at equal intervals.

[0028] To further enhance the accuracy of chip generation rate detection, in this invention, the sensing column consists of an electrically driven support column 25 and a weight sensing column 26. The weight sensing column 26 is mounted on a mounting frame 22 and supported by a smooth-surfaced sliding roller 27 on the upper part of the chip conveyor belt 23. When chips fall onto the upper part of the chip conveyor belt 23, the weight acts on the sliding roller 27 through the chip conveyor belt 23, and then on the weight sensing column 26 through the sliding roller 27. This causes multiple weight sensing columns 26 to bear pressure together, thereby changing the average value of the detection value of the weight sensing column 26. Under the control of a pre-set program... Under the control, the weight change of the weight sensing column 26 directly controls the electric support column 25 to produce a corresponding length change. At the same time, the power of the drive motor 24 is also changed through program control. Specifically, when the weight detected by the weight sensing column 26 increases, the length of the electric support column 25 shortens, which increases the tilt angle of the mounting frame 22 and the chip conveyor belt 23 on the mounting frame 22. On the one hand, the increase in tilt angle improves the efficiency of the chips rolling along the movement direction of the chip conveyor belt 23. On the other hand, the increase in tilt angle makes the channel cross section for the chips to leave the machine tool body 1 larger, thereby reducing the difficulty of chip removal.

[0029] In a preferred embodiment of the present invention, a chip discharge port 13 is provided on one side of the machine tool body 1, a waste chip box 3 is installed outside the chip discharge port 13, the chip discharge belt 23 extends through the chip discharge port 13 to the top of the waste chip box 3, a hinge rod 31 is rotatably installed in the chip discharge groove 12, one end of the mounting bracket 22 is fixedly installed on the hinge rod 31, and the end of the mounting bracket 22 away from the hinge rod 31 is located above the sensing column.

[0030] The mounting bracket 22 has a connecting rod 4 installed above the waste bin 3. A cleaning brush is installed on the connecting rod 4, and the cleaning brush is in contact with the bottom surface of the waste conveyor belt 23.

[0031] Under the action of the chip conveyor belt 23, the debris is continuously transported to the waste bin 3. The staff can clean the waste bin 3 regularly. During this process, the chip conveyor belt 23 continues to operate and, during its rotation after discharging the waste, it generates relative movement with the cleaning brush on the connecting rod 4. The cleaning brush cleans the chip conveyor belt 23, thereby causing the debris in the gaps of the chip conveyor belt 23 to fall out, enhancing the transportation effect of the chip conveyor belt 23 and reducing the weight change caused by the increase of waste in the gaps of the chip conveyor belt 23. At the same time, the connecting rod 4 is installed on the mounting frame 22. Therefore, during the deflection of the mounting frame 22, the chip conveyor belt 23 is always not completely separated from the cleaning brush, thus allowing the cleaning operation to continue.

[0032] In a preferred embodiment of the present invention, one end of the connecting rod 4 is hinged to the mounting frame 22. A hydraulic push rod 41 and a tension spring 42 are fixedly mounted on the mounting frame 22. The middle part of the connecting rod 4 is connected to the hydraulic push rod 41 and the tension spring 42. A hydraulic telescopic rod 43 is fixedly mounted on the waste bin 3. The hydraulic telescopic rod 43 is located on the descent path of the mounting frame 22. The hydraulic telescopic rod 43 and the hydraulic push rod 41 are connected by a series pipe 44.

[0033] The cleaning brush consists of an elastic frame 5 and a brush body 51. The elastic frame 5 is made of elastic material. The elastic frame 5 has evenly distributed material drop grooves 52 along the movement direction of the chip removal belt 23. The brush body 51 is fixedly installed on the elastic frame 5. The brush body 51 and the material drop grooves 52 are arranged alternately. The arrangement of the brush body 51 and the material drop grooves 52 allows the cleaning brush to perform multiple cleanings in a sequential manner when cleaning the chip removal belt 23. This enhances the cleaning effect and facilitates the removal of waste chips into the waste bin through the material drop grooves 52.

[0034] An adsorption block 53 is fixedly installed on the elastic frame 5, and an adsorption groove is provided on the mounting frame 22. The adsorption block 53 is magnetically adsorbed to the adsorption groove.

[0035] To adjust the resistance of the cleaning brush to the operation of the chip conveyor belt 23 during changes in chip removal speed, in this invention, the connecting rod 4 is hinged to the mounting frame 22, and its middle part is connected to the mounting frame 22 by a hydraulic push rod 41 and a tension spring 42. When the tilt angle of the mounting frame 22 changes, the pressure of the mounting frame 22 on the hydraulic telescopic rod 43 changes, thereby changing the hydraulic strength inside the hydraulic push rod 41 and the hydraulic telescopic rod 43. This, in conjunction with the tension spring 42, changes the deflection angle of the connecting rod 4. Specifically, when the mounting frame 22 tilts downward, the operating speed of the chip conveyor belt 23 increases, the hydraulic telescopic rod 43 is compressed, and the hydraulic oil inside it is transported to the hydraulic push rod 41 through the series pipe 44. The push rod 41 extends to push the connecting rod 4 to deflect and pull the tension spring 42. During this process, as the end of the connecting rod 4 gradually moves away from the mounting bracket 22, one end of the elastic frame 5 is pulled, causing the elastic frame 5, brush body 51, and adsorption block 53 to separate from the chip removal belt 23 and adsorption groove one by one in sequence. At this time, the effective range of the cleaning brush and the chip removal belt 23 gradually decreases, thereby gradually reducing the resistance of the cleaning brush to the operation of the chip removal belt 23 and reducing the load on the drive motor 24. Conversely, when the amount of chip removal decreases, the operating speed of the chip removal belt 23 slows down. At this time, under the reset action of the tension spring 42, the connecting rod 4 and the cleaning brush gradually reset, thereby gradually increasing the effective area of ​​the cleaning brush on the chip removal belt 23 and enhancing the cleaning effect on the chip removal belt 23.

[0036] In a preferred embodiment of the present invention, a one-way slow-release component is fixedly installed at the connection point between the hydraulic push rod 41 and the series pipe 44. The one-way slow-release component consists of a connecting pipe 6, a conical plug 61, and a release pipe 62. The connecting pipe 6 is fixedly connected between the hydraulic telescopic rod 43 and the series pipe 44. The conical plug 61 is fixedly installed inside the connecting pipe 6. The conical plug 61 is made of elastic material. The diameter of the end of the conical plug 61 facing the series pipe 44 is smaller than the diameter of the end facing the hydraulic telescopic rod 43. The release pipe 62 is fixedly installed on the conical plug 61 and penetrates the conical plug 61.

[0037] The connecting pipe 6 is threaded with a fastening bolt 63, and the release pipe 62 is provided with an adjustment groove 64. An adjustment piston 65 is slidably installed in the adjustment groove 64, and the adjustment piston 65 is rotatably connected to the fastening bolt 63.

[0038] To slow down the resetting rate of the cleaning brush, facilitating the gradual cleaning of debris filling the gaps in the chip removal belt 23 during rapid operation, a one-way slow-release component is incorporated in this invention. The connecting pipe 6 connects the series pipe 44 to the hydraulic telescopic rod 43, while the conical plug 61, in conjunction with the release pipe 62, controls the rate at which hydraulic oil enters the hydraulic telescopic rod 43. Specifically, when the mounting bracket 22 deflects downwards, hydraulic oil flows from the hydraulic telescopic rod 43 towards the series pipe 44. At this time, the conical plug 61 gradually opens under hydraulic pressure, allowing hydraulic oil to smoothly enter the hydraulic push rod 41, causing the connecting rod 4 to deflect rapidly. When the mounting bracket 22 returns to its original position... When in position, under the action of the tension spring 42, the hydraulic push rod 41 is squeezed, causing the hydraulic oil to flow towards the hydraulic telescopic rod 43. Under the action of hydraulic pressure and the elasticity of the conical plug 61 itself, the conical plug 61 closes, and the hydraulic oil can only be slowly released to the hydraulic telescopic rod 43 through the release pipe 62, thereby controlling the reset rate of the connecting rod 4. At the same time, during long-term use, when the equipment is under maintenance, the staff can actively adjust the fastening bolt 63 to push the adjusting piston 65 to move in the adjusting groove 64, thereby adjusting the cross-sectional size of the release pipe 62, so that the reset rate of the connecting rod 4 can be manually adjusted to adapt to different processing techniques.
