Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy die casting equipment, and in particular to a laser processing equipment for aluminum alloy die castings with an auxiliary positioning mechanism. Background Technology

[0002] Aluminum alloy die castings are widely used in many fields due to their excellent performance. Laser processing is an important method in the subsequent machining of aluminum alloy die castings. For example, lasers can be used for cutting, laser welding, and laser surface treatment, enabling precise machining of the die castings and improving product accuracy and quality.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing laser processing equipment for aluminum alloy die castings has some shortcomings in actual use. When clamping and fixing aluminum alloy die castings, traditional clamping methods are often difficult to adapt to die castings of different widths or irregular shapes, which can easily lead to unstable clamping. During laser processing, the die castings are prone to displacement, affecting the accuracy and quality of laser processing. Therefore, to address the above problems, an aluminum alloy die casting laser processing equipment with an auxiliary positioning mechanism is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing laser processing equipment for aluminum alloy die castings, which has defects in the clamping and fixing process. Traditional clamping methods are difficult to adapt to die castings of different widths and irregular shapes, and are prone to unstable clamping and displacement of the die castings, which seriously affect the accuracy and quality of laser processing. Therefore, this invention proposes a laser processing equipment for aluminum alloy die castings with an auxiliary positioning mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laser processing device for aluminum alloy die-casting parts with an auxiliary positioning mechanism, comprising a laser cutting table, a plurality of operation buttons mounted on the surface of the laser cutting table, a movable laser mounted on the upper surface of the laser cutting table, and a clamping device provided on the upper surface of the laser cutting table, the clamping device comprising a U-shaped frame, the U-shaped frame being fixedly connected to the upper surface of the laser cutting table, two threaded rods being threadedly inserted into the U-shaped frame, one end of the threaded rod being fixedly connected to a rotating shaft, and the end of the threaded rod away from the rotating shaft being rotatably connected to a clamping plate, the clamping plate being slidably connected to the upper surface of the laser cutting table.

[0006] The effect achieved by the above components is as follows: by setting a clamping device consisting of a U-shaped frame, threaded rod, and clamping plate on the upper surface of the laser cutting table, the clamping plate spacing can be flexibly adjusted by using the threaded transmission of the threaded rod, thereby adapting to and firmly clamping aluminum alloy die-casting parts of different widths. This effectively avoids displacement of the die-casting parts during laser processing, ensures the stability and accuracy of laser processing, and enhances the applicability of the equipment to workpieces of different specifications.

[0007] Preferably, the surface of the U-shaped frame is provided with sliding holes, and two sliding plates are slidably connected in the sliding holes. The sliding plates are fixedly connected to one side of the clamp.

[0008] The effect achieved by the above components is that the slide plate slides in the sliding hole and is fixedly connected to the clamping plate, so that the clamping plate obtains stable guidance during movement, enhances the smoothness of the movement of the clamping plate, avoids shaking or displacement when adjusting the position, further ensures the accuracy and firmness of clamping the aluminum alloy die casting, and improves the laser processing effect.

[0009] Preferably, the surface of the clamping plate is provided with a plurality of circular grooves, the inner wall of the circular grooves is fixedly connected to a spring, the other end of the spring is fixedly connected to a circular rod, and the circular rod is slidably connected to the inner wall of the circular groove.

[0010] The effect achieved by the above components is that when performing laser processing on irregular aluminum alloy die-cast parts, the round rod can significantly increase the contact area with the workpiece, effectively expand the clamping range, firmly clamp irregular workpieces that are originally difficult to fix, and improve the practicality of the device.

[0011] Preferably, the arc surface of the rotating shaft is provided with a plurality of strip grooves, and the plurality of strip grooves are arranged in a circumferential array.

[0012] The effect achieved by the above components is that the circumferentially arrayed grooves on the arc surface of the rotating shaft increase the friction between the shaft and the operator's fingers, making it less likely for the operator to slip during rotation.

[0013] Preferably, a soft pad, which is made of silicone rubber, is fixedly connected to the arc surface of the round rod.

[0014] The effects achieved by the above components are as follows: when clamping a workpiece, the silicone rubber pad on the arc surface of the round rod adheres tightly to the workpiece surface due to its own softness, further increasing the contact area with the workpiece and enhancing the clamping firmness; on the other hand, the silicone rubber material is flexible and can effectively prevent scratching or damaging the workpiece surface during clamping, thus playing a good protective role.

[0015] Preferably, the surface of the laser cutting table is provided with an auxiliary device, the auxiliary device including a U-shaped block, the U-shaped block being fixedly connected to the surface of the laser cutting table, a fixing rod being fixedly connected to the inner wall of the U-shaped block, a baffle being rotatably connected to the arc surface of the fixing rod, two support rods being fixedly connected to the surface of the baffle, a screw being fixedly connected to the surface of the U-shaped block, and an arc plate being threadedly connected to the arc surface of the screw.

[0016] The aforementioned components achieve the following effect: by setting up auxiliary devices, the operation buttons are prevented from being accidentally touched. When the operator sets the parameters, the baffle is rotated to cover the operation buttons of the laser cutting table. The support rod abuts against the surface of the laser cutting platform, and the baffle forms a physical barrier, which can prevent the operation buttons from being accidentally triggered by the operator when moving around the equipment due to accidental scratches or touches. This reduces the occurrence of abnormal equipment start-ups, incorrect parameter modifications, and other situations, and improves the stability of the laser cutting table.

[0017] Preferably, the arc surface of the fixing rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the baffle and the U-shaped block, respectively.

[0018] The effect achieved by the above components is that when the arc-shaped plate on the rotating screw releases the limit on the baffle, the torque of the torsion spring will then drive the baffle to automatically rotate upward and open on the arc surface of the fixed rod, thus improving the convenience of the device.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, a clamping device consisting of a U-shaped frame, a threaded rod, and clamping plates is set on the upper surface of the laser cutting table. The spacing between the clamping plates can be flexibly adjusted by the threaded transmission of the threaded rod, thereby adapting to and firmly clamping aluminum alloy die-casting parts of different widths. This effectively avoids displacement of the die-casting parts during laser processing, ensures the stability and accuracy of laser processing, and enhances the applicability of the equipment to workpieces of different specifications.

[0021] 2. In this utility model, by setting an auxiliary device, the effect of preventing accidental touch of the operation button is achieved. When the operator sets the parameters, the baffle is rotated to cover the operation button of the laser cutting table. The support rod abuts against the surface of the laser cutting platform, and the baffle forms a physical shielding barrier. This can prevent the operator from accidentally triggering the operation button due to unintentional scratching or touching when moving around the equipment, reduce the occurrence of abnormal equipment start-up, incorrect parameter modification, etc., and improve the stability of the laser cutting table.

[0028] Reference Figures 1-5 As shown, this utility model provides a technical solution: a laser processing device for aluminum alloy die-casting parts with an auxiliary positioning mechanism, including a laser cutting table 1. Several operation buttons 5 are installed on the surface of the laser cutting table 1. A movable laser 2 is installed on the upper surface of the laser cutting table 1. A clamping device 3 is provided on the upper surface of the laser cutting table 1. By setting the clamping device 3, which consists of a U-shaped frame, a threaded rod 302, and clamping plates 304, on the upper surface of the laser cutting table 1, the spacing of the clamping plates 304 can be flexibly adjusted using the threaded transmission of the threaded rod 302. This allows for the adaptation and firm clamping of aluminum alloy die-casting parts of different widths, effectively preventing displacement of the die-casting parts during laser processing. The movement ensures the stability and accuracy of laser processing and enhances the applicability of the equipment to workpieces of different specifications. An auxiliary device 4 is set on the surface of the laser cutting table 1. By setting the auxiliary device 4, the operation button 5 is prevented from being accidentally touched. When the operator sets the parameters, the baffle 43 is rotated to cover the operation button 5 of the laser cutting table 1. The support rod 46 abuts against the surface of the laser cutting platform, and the baffle 43 forms a physical shielding barrier, which can prevent the operator from accidentally triggering the operation button 5 due to scratching or touching when moving around the equipment. This reduces the occurrence of abnormal equipment start-up, incorrect parameter modification, etc., and improves the stability of the laser cutting table 1.

[0029] The specific configuration and function of its clamping device 3 and auxiliary device 4 will be explained in detail below.

[0030] Reference Figure 2 and Figure 3 As shown, in this embodiment: the clamping device 3 includes a U-shaped frame 301, which is fixedly connected to the upper surface of the laser cutting table 1. Two threaded rods 302 are threadedly inserted into the U-shaped frame 301. One end of each threaded rod 302 is fixedly connected to a rotating shaft 303, and the end of the threaded rod 302 away from the rotating shaft 303 is rotatably connected to a clamping plate 304. The clamping plate 304 is slidably connected to the upper surface of the laser cutting table 1. A sliding hole 305 is provided on the surface of the U-shaped frame 301, and two sliding plates 306 are slidably connected within the sliding hole 305. The sliding plate 306 is fixedly connected to one side of the clamping plate 304. The sliding plate 306 slides within the sliding hole 305 and is fixedly connected to the clamping plate 304, providing stable guidance for the clamping plate 304 during movement. This enhances the smoothness of the clamping plate 304's movement and prevents it from wobbling or shifting when adjusting its position. This further ensures the accuracy and firmness of clamping the aluminum alloy die-casting parts and improves the laser processing effect. Several circular grooves 307 are formed on the surface of the clamping plate 304. Springs 308 are fixedly connected to the inner wall of the circular grooves 307. The other side of the spring 308... A round rod 309 is fixedly connected to the end, and the round rod 309 is slidably connected to the inner wall of the round groove 307. When performing laser processing on irregular aluminum alloy die-cast parts, the round rod 309 can significantly increase the contact area with the workpiece, effectively expanding the clamping range and firmly clamping irregular workpieces that were originally difficult to fix, thus improving the practicality of the device. The arc surface of the rotating shaft 303 is provided with several strip grooves 310, which are arranged in a circumferential array. The strip grooves 310 arranged in a circumferential array on the arc surface of the rotating shaft 303 increase the... To reduce friction between the rod and the operator's fingers and prevent slippage during rotation, a soft pad 311 is fixedly connected to the arc surface of the rod 309. The soft pad 311 is made of silicone rubber. When clamping the workpiece, the silicone rubber soft pad 311 on the arc surface of the rod 309 adheres tightly to the workpiece surface due to its softness, further increasing the contact area and enhancing the clamping firmness. On the other hand, the flexible texture of silicone rubber effectively prevents scratching or damaging the workpiece surface during clamping, providing good protection.

[0031] Reference Figure 4 and Figure 5As shown, specifically, the auxiliary device 4 includes a U-shaped block 41, which is fixedly connected to the surface of the laser cutting table 1. A fixing rod 42 is fixedly connected to the inner wall of the U-shaped block 41. A baffle 43 is rotatably connected to the arc surface of the fixing rod 42. Two support rods 46 are fixedly connected to the surface of the baffle 43. A screw 44 is fixedly connected to the surface of the U-shaped block 41. An arc plate 45 is threadedly connected to the arc surface of the screw 44. Two torsion springs 47 are sleeved on the arc surface of the fixing rod 42. The two ends of the torsion springs 47 are fixedly connected to the baffle 43 and the U-shaped block 41, respectively. When the arc plate 45 on the screw 44 is rotated to release the restriction on the baffle 43, the torque of the torsion springs 47 will then drive the baffle 43 to automatically rotate upward and open on the arc surface of the fixing rod 42, which improves the convenience of the device.

[0032] The working principle is as follows: rotating the shaft 303 drives the threaded rod 302, which is threadedly connected to the U-shaped frame 301, to rotate. This threaded transmission causes the clamping plate 304 to slide on the surface of the laser cutting table 1, thereby adjusting the spacing of the clamping plates 304 to accommodate aluminum alloy die-cast parts of different widths. Simultaneously, the sliding plate 306 within the sliding hole 305 on the surface of the U-shaped frame 301 is fixed to the clamping plate 304, providing stable guidance for its movement, preventing wobbling and ensuring clamping accuracy. For irregular die-cast parts, the spring 308 within the circular groove 307 on the clamping plate 304 pushes the circular rod 309 to adaptively conform to the workpiece surface, increasing the contact area and expanding the clamping range. The silicone rubber pad 311 on the arc surface of the circular rod 309 further tightens the fit against the workpiece, increasing friction and protecting the workpiece surface. Furthermore, the circumferential array of strip grooves 310 on the arc surface of the shaft 303 increases friction with the operator's fingers, facilitating the application of force to rotate the shaft 303 and achieving precise adjustment of the clamping plate 304's position.

[0033] When protection is needed for operation button 5, push the baffle 43 to rotate on the arc surface of the fixing rod 42 until the support rod 46 on the baffle 43 abuts against the surface of the laser cutting table 1. At this time, the baffle 43 covers and shields the operation button 5. Then rotate the arc plate 45 on the screw 44 until the arc plate 45 abuts against the baffle 43 to fix the baffle 43. This prevents the operation button 5 from being accidentally triggered by the operator when moving around the equipment due to accidental scratches or touches, reducing the occurrence of abnormal equipment start-up, incorrect parameter modification, etc. When the operator needs to use operation button 5, rotate the arc plate 45 on the screw 44 until the arc plate 45 no longer abuts against the baffle 43. At this time, the torque of the torsion spring 47 will cause the baffle 43 to automatically rotate and open on the arc surface of the fixing rod 42, and then the operator can operate operation button 5.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
