Description

Technical Field

[0001] This utility model relates to the field of horizontal machining centers, and more particularly to a horizontal machining center with two workstations. Background Technology

[0002] Horizontal machining centers, with their high precision and efficiency, are widely used in aerospace, automotive manufacturing, mold making, and other fields. Dual-station horizontal machining centers further optimize the production process by having two worktables work alternately, enabling simultaneous workpiece clamping and machining, significantly reducing auxiliary time and improving equipment utilization and production efficiency.

[0003] Existing clamping devices also have significant limitations in workpiece clamping. The clamping force adjustment of some devices is not precise enough. During machining, insufficient clamping force can easily cause workpiece displacement or vibration, affecting machining accuracy and surface quality, and even leading to safety accidents. Excessive clamping force can cause workpiece deformation, especially for thin-walled, precision workpieces. Furthermore, existing clamping operations largely rely on manual adjustment, resulting in low automation, cumbersome operation, and difficulty in meeting the demands of efficient, continuous machining. The consistency of manual operation is also difficult to guarantee, increasing the instability of machining quality.

[0004] Existing dual-station horizontal machining centers still face numerous technical bottlenecks in practical applications. Regarding visualization, the viewing glass on the protective door is easily contaminated by chips and coolant splashes, and lacks an efficient cleaning mechanism, leading to reduced light transmittance. This makes it difficult for operators to clearly observe the machining status, affecting machining accuracy control and handling of abnormal situations. Although some equipment is equipped with lighting devices, the light distribution is uneven and the brightness is not adjustable, failing to meet the special lighting requirements of precision machining and increasing the difficulty of machining quality control.

[0033] Reference Figure 1-5This utility model provides an embodiment of a horizontal machining center with dual workstations, including a bed 1. A transmission mechanism 2 is fixedly connected to one side of the bed 1, and a spindle 3 is fixedly connected to one side of the transmission mechanism 2. A support platform 4 is fixedly connected to the other side of the bed 1. A worktable 5 is rotatably connected to the top of the support platform 4. A motor is fixedly connected to the top of the support platform 4, with its output end penetrating and rotatably connected to the support platform 4, and also fixedly connected to the worktable 5. A slip ring is provided at the bottom of the motor. Sliding doors 7 are slidably connected to both sides of one end of the bed 1, with a handle at one end of each sliding door 7 for easy opening. Tempered glass 8 is provided at one end of each sliding door 7. A protective plate 9 is fixedly connected to the center of the top of the worktable 5. Rotary tables 11 are rotatably connected to both sides of the top of the worktable 5.

The top of the rotating table 11 is fixedly connected to a support plate 14, and the rotating plate 13 and the support plate 14 are rotatably connected. Sliding blocks 15 are slidably connected through both ends of the top of the support plate 14. A transmission component is set at the bottom of the sliding block 15. A cleaning component is set at the top of the bed 1. The slip ring ensures that the power and control signals are transmitted continuously during the rotation of the motor, ensuring the stability and reliability of the rotation of the worktable 5 and the rotating table 11, and avoiding equipment failure due to electrical connection problems. The tempered glass 8 on the sliding door 7 makes it easy to observe the processing status. The cleaning component can effectively keep the glass clean and the machine tool interior relatively tidy, which is conducive to the operator monitoring the processing process in real time, timely detection and handling of abnormalities. The dual-station design combines the rotation function of the worktable 5 and the rotating table 11. A cabinet door that can be rotated and opened is set on one side of the bed 1. While processing at one station, workpiece clamping, tool changing and other preparation work can be carried out at the other station, which greatly shortens the processing auxiliary time and improves equipment utilization and production efficiency.

[0034] The transmission assembly includes an L-shaped rotating rod 17, the top of which is rotatably connected to one side of the bottom of a sliding block 15, and the L-shaped rotating rod 17 is rotatably connected to a rotating plate 13. A clamping block 16 is fixedly connected to the top of each sliding block 15, and a fixing block 33 is fixedly connected to the other side of the bottom of each sliding block 15.

Driven by the hydraulic cylinder 19, the two clamping blocks 16 move synchronously towards or away from each other, which can quickly complete the clamping and loosening operation of the workpiece. Compared with the traditional manual clamping method, it greatly shortens the clamping time and improves the processing efficiency. The cleaning component includes a servo motor 22, which is fixedly connected to both sides of the top of the bed 1. The output end of the servo motor 22 passes through and is rotatably connected to the top of the bed 1. The output end of the servo motor 22 is fixedly connected to the lead screw 24.

A telescopic hose 27 is fixedly connected to the output end of the fan 26. The telescopic hose 27 and the air outlet duct 25 are slidably connected to each other. The scraper 23 and the air outlet duct are also fixedly connected to the top of the bed 1. The coordinated operation of 25 can quickly and effectively remove stains, chips, dust and other debris from the tempered glass 8 on the sliding door 7, maintaining good visibility and providing operators with a clear field of vision. A lighting lamp 29 is fixedly connected to the inner top wall of the bed 1. A lampshade 30 is fixedly connected to the bottom of the lighting lamp 29. A filter 31 is slidably connected through one end of the outer ring of the lampshade 30. Elastic plates 32 are fixedly connected to both sides of the outer ring of the filter 31. By switching the filter 31, the spectral characteristics and penetration ability of the light can be changed to adapt to the needs of different material processing and processing procedures. For example, when processing light-sensitive materials, using a blue light filter 31 can prevent the material from being affected by light and causing changes in its performance; when observing the internal details of a workpiece, using an anti-reflection filter 31 can enhance the light penetration and facilitate clearer observation. The sliding design of the filter 31 and the assistance of the elastic plate 32 allow operators to easily and quickly switch the filter 31 without complicated tools or operating procedures, improving the convenience and efficiency of operation. A control panel 6 is fixedly connected to one side of the bed 1, and a cooling mechanism 10 is provided at one end inside the bed 1. The cooling mechanism 10 includes a universal bamboo tube, a liquid storage tank, a centrifugal pump, and a transmission pipeline.

[0035] Working Principle: First, the motor inside the support table 4 drives the worktable 5 to rotate, realizing the switching between the two workstations. When the workpiece on one workstation is being processed under the spindle 3, the operator can operate at the other workstation by rotating the cabinet door on one side of the bed 1. The motor inside the worktable 5 drives the rotating table 11 to rotate, adjusting the workpiece angle. At the same time, the hydraulic cylinder 19 pushes the connecting column 18, causing the sliding blocks 15 and clamping blocks 16 on both sides to move in opposite directions, driving the L-shaped rotating rods 17 on both sides to rotate. The rotation of the L-shaped rotating rods 17 on both sides drives the rotating plate 13 to rotate, causing the L-shaped rotating rods 17 at both ends to rotate, driving the sliding blocks 15 and clamping blocks 16 at both ends to move in opposite directions. The clamping blocks 16 move synchronously towards or away from each other, completing the rapid clamping and release of the workpiece, realizing parallel clamping and processing, improving efficiency. The transmission mechanism 2 stably transmits power to the spindle 3, driving the spindle 3 to rotate at high speed, driving the cutting tool to perform milling, drilling and other processing operations. The rotation function of the worktable 5 and the rotary table 11 allows the workpiece to be processed in different postures and positions, meeting the multi-process processing requirements of complex parts. When the workpiece is being processed, the servo motor 22 is powered on and drives the lead screw 24 to rotate. The scraper 23 and the air outlet duct 25, which are threadedly connected to the lead screw 24, move linearly back and forth along the lead screw 24 under the guidance of the sliding rod 28. The fan 26 starts first and delivers compressed air to the air outlet duct 25 through the telescopic hose 27, blowing out a high-pressure airflow to first clean the coolant and dirt such as iron filings and dust. Then the scraper 23 scrapes away the remaining dirt on the surface of the tempered glass 8 on the sliding door 7, keeping the glass clean and easy to observe. The lighting lamp 29 is powered on and emits light, which is emitted through the lampshade 30 to illuminate the processing area. When it is necessary to adjust the light characteristics, the operator can manually squeeze the elastic plate 32 to slide out and replace the filter 31. Switching between different filters 31 changes the spectral characteristics and penetration ability of the light to meet the needs of different processing scenarios. The operator sends control signals through the buttons, knobs and other components on the control panel 6. These signals are transmitted through the circuit to control the operating parameters of the equipment, realizing precise control of various functional modules of the machine tool and ensuring that the processing proceeds smoothly according to the predetermined program.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
