Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, specifically relating to a multi-station cutting device for automotive parts processing. Background Technology

[0002] In the current era of rapid development in the automotive manufacturing industry, the processing precision and production efficiency of automotive parts have become key indicators for measuring manufacturing level. Among them, cutting (one of the operations of milling, turning or drilling) is the core link in the forming of parts, which puts extremely high demands on the performance of processing equipment. In particular, multi-station cutting devices, with their advantage of being able to process multiple parts at the same time, are widely used in the mass production of complex parts.

[0003] Existing cutting devices for automotive parts processing utilize the relative movement of the tool and the workpiece, employing the shearing force of the high-speed rotating tool edge to mill excess material from the workpiece surface, achieving the specified dimensions, shape, and surface quality. To prevent displacement during milling, a clamping assembly is needed to securely hold the workpiece. However, automotive parts come in various shapes, ranging from square structures like engine blocks to round rotating parts like drive shafts. The clamping and securing requirements differ significantly for different shapes. Traditional clamping assemblies typically use specialized fixtures that can only accommodate parts of a single shape. Square fixtures cannot securely hold round workpieces, leading to radial slippage; conversely, round fixtures struggle to hold square workpieces, potentially causing circumferential offset during processing. This "one-clamp-one-use" approach not only increases the time cost of fixture changes and reduces equipment utilization but also risks causing positioning datum deviations due to frequent fixture replacements, affecting machining accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a multi-station cutting device for processing automotive parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station cutting device for processing automotive parts, comprising:

[0006] A machine base, the top of which is connected to a vertical frame and the vertical frame is provided with a cutting assembly for cutting parts. The cutting assembly is slidably connected to the vertical frame through a feeding assembly and can achieve a feeding action along a preset trajectory.

[0007] A fixing component is located on the top of the machine base and below the cutting component. The fixing component is used to clamp and fix the parts to be cut. During the cutting operation, the parts can be firmly locked in the preset processing position. The fixing component includes two sets of fixing tables and adjustable clamps connected to the fixing tables. By adjusting the clamping head of the adjustable clamp, square and round parts can be firmly clamped and fixed.

[0008] Preferably, the machine base is provided with a processing table on the top, and two sets of fixed tables are respectively connected to the two ends of the top of the processing table. A lead screw is rotatably connected to the fixed table through a bearing, and a clamping block is connected to the lead screw through a lead screw nut.

[0009] Preferably, one end of the fixed platform is connected to a servo motor and the output shaft of the servo motor is connected to a lead screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The position of the clamping head of the adjustable fixture can be flexibly adjusted by the threaded rod, so that the clamping head can contact the square parts and clamp the square parts in conjunction with the clamping block. The arc frame and the clamping block can be adapted to round parts of different diameters. The sliding distance of the clamping block can be freely adjusted according to the size of the parts. Whether it is a small square connector or a large round shaft part, the device can provide stable fixation. There is no need to equip each part with a special fixture. The fixation of parts of different shapes can be completed through simple operation, eliminating the steps of fixture replacement and debugging, saving a lot of preparation time and improving processing efficiency.

[0017] (2) The coordinated movement of the feeding assembly and the X-axis servo screw linear module enables multiple parts to be cut at multiple stations after being clamped once by the fixed table.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] This utility model provides, for example Figure 1-5 The multi-station cutting device for machining automotive parts shown includes:

[0028] A base 1 is provided, and a stand 2 is connected to the top of the base 1. The stand 2 is provided with a cutting assembly 3 for cutting parts. The cutting assembly 3 is slidably connected to the stand 2 through a feeding assembly 4 and can perform a feeding action along a preset trajectory. This feeding action can accurately control the relative position between the cutting assembly 3 and the parts, meet the cutting requirements of parts at different depths and different work positions, and ensure that the cutting operation is carried out smoothly according to the preset processing parameters.

[0029] The fixing component 5 is located on the top of the machine base 1 and below the cutting component 3. The fixing component 5 is used to clamp and fix the parts to be cut. During the cutting operation, the parts can be firmly locked in the preset processing position, effectively avoiding the displacement of the parts due to the cutting force and affecting the processing accuracy. The fixing component 5 includes two sets of fixing tables 6 and adjustable clamps 7 connected to the fixing tables 6. By adjusting the clamping head 8 of the adjustable clamp 7, square and round parts can be firmly clamped and fixed, realizing universal clamping of parts of different shapes, eliminating the need for frequent clamping, and improving the versatility and processing efficiency of the device.

[0030] The machine base 1 is equipped with a processing table 9 on the top, which provides a stable bearing platform for the processing of parts. Two sets of fixed tables 6 are respectively connected to the top two ends of the processing table 9. The multi-station setting facilitates the processing of multiple sets of parts in conjunction with the feeding assembly 4. The fixed table 6 is rotatably connected to a lead screw 10 through a bearing, and a clamping block 11 is driven to the lead screw 10 through a lead screw nut. The rotation of the lead screw 10 can be converted into the linear motion of the clamping block 11 through the lead screw nut, thereby realizing the clamping and releasing action of the clamping block 11 on the parts. The transmission is smooth and the precision is high.

[0031] One end of the fixed platform 6 is connected to a servo motor 12, and the output shaft of the servo motor 12 is connected to the lead screw 10. The servo motor 12 can provide precise power output for the rotation of the lead screw 10. The rotation amount of the lead screw 10 can be controlled by controlling the speed and rotation angle of the servo motor 12, thereby controlling the moving distance of the clamping block 11. The top of the fixed platform 6 is provided with two sets of sliding grooves, and the bottom sides of the clamping block 11 are slidably connected to the sliding grooves by sliders. The cooperation between the sliding grooves and the sliders can guide the movement of the clamping block 11, prevent the clamping block 11 from deviating during the movement, ensure the linearity and stability of the movement of the clamping block 11, and further improve the clamping accuracy.

[0032] The adjustable clamp 7 includes a V-frame 13, which provides a stable mounting base for other components of the adjustable clamp 7. Both ends of the V-frame 13 are connected to transmission frames 14, which provide support for the installation and transmission of the threaded rod 15. An arc frame 17 for fitting circular parts is connected to the V-frame 13. The arc frame 17 can adapt to the outer contour of the circular parts, increasing the contact area with the circular parts and improving the clamping stability of the circular parts. The transmission frame 14 is rotatably connected to the threaded rod 15 through a threaded cylinder, and one end of the threaded rod 15 rotates through the arc frame 17 and connects to the clamping head 8. By rotating the threaded rod 15, the position of the clamping head 8 can be adjusted, so that the clamping head 8 can be adapted and adjusted according to the size and shape of the square parts, enhancing the flexibility and reliability of clamping.

[0033] The clamping head 8 is equipped with a suction cup 16. The suction cup 16 can further enhance the fixing effect of the clamping head 8 on the parts through adsorption. Especially for parts with flat surfaces, it can increase the adsorption force on the basis of the clamping force to prevent the parts from loosening or sliding during pre-fixation.

[0034] The cutting assembly 3 includes a mounting frame 18, which provides a mounting carrier for other components of the cutting assembly 3. A geared motor 19 is mounted on the top of the mounting frame 18, and the output shaft of the geared motor 19 is connected to a first transmission component 20. The geared motor 19 provides suitable power and speed for the cutting operation, and the first transmission component 20 transmits the power of the geared motor 19. A rotating shaft 21 is rotatably connected to the front end of the mounting frame 18 via a bearing, and a second transmission component 22 is connected to the top of the rotating shaft 21. The bearing ensures the flexible rotation of the rotating shaft 21, and the second transmission component 22 receives the power transmitted by the first transmission component 20. The first transmission component 20 and the second transmission component 22... The transmission components 22 are connected by a transmission belt 23, which enables smooth power transmission and reduces impact and vibration during power transmission. The bottom of the rotating shaft 21 is connected to a milling head 24, and a milling cutter 25 is mounted on the milling head 24. The rotation of the rotating shaft 21 can drive the milling head 24 and the milling cutter 25 to rotate, thereby realizing the cutting and machining of parts. The first transmission component 20 and the second transmission component 22 are both sprockets, while the transmission belt 23 is a chain. The transmission through the meshing of the chain and the sprocket has the characteristics of accurate transmission ratio and large power transmission. It can stably transmit power at high speed and is not easy to slip, ensuring the reliability of power transmission.

[0035] The feeding assembly 4 includes a Z-axis servo lead screw linear module 26. The Z-axis servo lead screw linear module 26 is mounted on the stand 2, and the Z-axis moving slide of the Z-axis servo lead screw linear module 26 is connected to the mounting frame 18. The Z-axis servo lead screw linear module 26 can accurately control the movement of the cutting assembly 3 in the Z-axis direction, realize the up and down feeding action of the cutting assembly 3, and ensure the accurate control of the cutting depth.

[0036] The base 1 is equipped with an X-axis servo lead screw linear module 27 on its top, and the X-axis moving slide of the X-axis servo lead screw linear module 27 is connected to the bottom center of the machining table 9. The X-axis servo lead screw linear module 27 can accurately control the movement of the machining table 9 in the X-axis direction, drive the parts fixed on the machining table 9 to move, realize multi-station cutting processing, eliminate the need for frequent clamping of parts, and improve processing efficiency and processing accuracy.

[0037] This multi-station cutting device for processing automotive parts, when placing a square part (a square automotive chassis connecting bracket), places the square part on the fixed table 6. Then, the transmission structure of the adjustable clamp 7 is operated first, rotating the handle at the outer end of the transmission frame 14, which drives the threaded rod 15 inside the transmission frame 14 to rotate. The threaded rod 15 pushes the clamping head 8 towards the square part. As the threaded rod 15 continues to rotate, the clamping head 8 gradually approaches and contacts the side of the square part, while the suction cup 16 gradually contacts the square part, creating a negative pressure between the inside of the suction cup 16 and the square part, firmly adhering to the surface of the part. At this time, the clamping head 8 plays a role in initial positioning and auxiliary support, preventing the part from shifting during the subsequent clamping process of the clamping block 11. After contacting and stabilizing the square component, the operator controls the servo motor 12 to start via the controller. The power output of the servo motor 12 is directly transmitted to the lead screw 10, which then begins to rotate. Since the lead screw 10 and the lead screw nut are tightly engaged by threads, the rotational motion of the lead screw 10 is converted into the linear motion of the lead screw nut. The clamping block 11 is fixedly connected to the lead screw nut, so the clamping block 11 will move along with the lead screw nut. The slide groove on the top of the fixed platform 6 forms a guiding constraint on the slider at the bottom of the clamping block 11, ensuring that the clamping block 11 can only slide smoothly to the other side of the square component along the slide groove direction until the anti-slip pad on the surface of the clamping block 11 is tightly attached to the side of the square component. At this time, the servo motor 12 automatically stops running, and the clamping head 8 completes the fixation of the square component.

[0038] If the part is circular (such as a circular shaft), the adjustable fixture 7 is reset, and then the circular part is placed on the fixed table 6. The inner arc surface of the arc frame 17 naturally fits the outer contour of the circular part. The inclusiveness of the arc structure provides initial positioning of the part, placing it in a roughly machining center position. Then, the operator controls the servo motor 12 to start through the controller. The lead screw 10 rotates, causing the clamping block 11 to slide along the slide. When the clamping block 11 approaches the circular part, since the arc frame 17 has already formed a partial circumferential support for the part, the clamping block 11 applies a clamping force from one side, forming a stable clamping space together with the arc frame 17. As the clamping block 11 continues to move, the clamping force gradually increases. Finally, under the combined action of the clamping force of the clamping block 11 and the supporting force of the arc frame 17, the circular part is stably fixed, providing a reliable guarantee for cutting.

[0039] When the parts need to be milled at a fixed position after being clamped and fixed, the Z-axis servo lead screw linear module 26 of the feeding assembly 4 receives the command and its internal motor drives the lead screw to rotate. The slider on the lead screw carries the cutting assembly 3 up and down along the guide rail on the stand 2. During the sliding process, the position sensor installed on the side of the cutting assembly 3 monitors the distance to the parts in real time and feeds the data back to the controller. When the milling cutter 25 reaches the preset initial cutting height, the controller issues a stop signal, the Z-axis servo lead screw linear module 26 stops moving, and the cutting assembly 3 remains in that position waiting for the cutting command. Then, the operator controls the reduction motor 19 of the cutting assembly 3 to start through the controller. The power is transmitted to the transmission belt 23 through the first transmission component 20. The transmission belt 23 drives the second transmission through friction. When component 22 rotates, the rotating shaft 21 connected to the second transmission component 22 rotates accordingly. The milling head 24 at the bottom of the rotating shaft 21 rotates synchronously. The milling cutter 25 installed in the bottom of the milling head 24 maintains a stable rotation under the action of centrifugal force. At the same time, the X-axis servo lead screw linear module 27 drives the slider at the bottom of the processing table 9 to move along the guide rail in the top of the machine base 1. The parts on the processing table 9 move horizontally together with the processing table 9. The feeding component 4 drives the cutting component 3 to feed slowly according to the preset cutting path. The milling cutter 25 contacts the surface of the part and begins to cut. During the cutting process, the moving speed of the processing table 9, the feed speed of the cutting component 3, and the rotation speed of the milling cutter 25 are kept coordinated by the controller to ensure that the cutting process is continuous and stable. The fixing component 5 always maintains the clamping force on the part to prevent the part from being displaced under the action of cutting force.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
