Description

Technical Field

[0001] This utility model relates to the field of skateboard bridge production technology, specifically a water-cooled cutting device for skateboard bridge production. Background Technology

[0002] Skateboarding evolved from surfing in the late 1950s and early 1960s. Skateboarding is a board sport in which athletes use their feet to glide on various terrains, surfaces, and specific facilities, performing a variety of complex gliding, jumping, spinning, and flipping maneuvers to the rhythm of music. Skateboard trucks are the core load-bearing and steering components of a skateboard, directly affecting the stability, flexibility, and control of the ride. Waterjet cutting technology, with its cold processing, high precision, and environmentally friendly characteristics, has become the ideal choice for processing irregularly shaped skateboard truck structures.

[0003] The existing waterjet cutting head has insufficient angle adjustment capability. A waterjet cutting head with a fixed angle cannot adjust the jet direction in real time according to the curved surface of the workpiece, which leads to the deviation of the cutting path or the need for multiple clamping and positioning, significantly reducing the processing efficiency. Therefore, we need to propose a waterjet cutting device for the production of sliding bridges. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] A water-jet cutting device for skateboard bridge production includes a workbench 1 and a water-jet cutting head 2. The top of the workbench 1 is provided with an adjustment component for adjusting the position of the water-jet cutting head 2. A connecting plate 4 is provided on the adjustment component. A power mechanism 5 for rotating and tilting the water-jet cutting head 2 is provided at the bottom of the connecting plate 4. The water-jet cutting head 2 achieves precise positioning in three-dimensional space through the adjustment component. Combined with the multi-angle adjustment capability of the power mechanism 5, it can adapt to the complex geometric contours of the skateboard bridge.

[0022] The power mechanism 5 includes a rotating component 51 and a tilting component 52. The rotating component 51 includes a mounting shell 5101, which is fixedly mounted on the bottom of the connecting plate 4. A turntable 5102 is rotatably mounted on the bottom of the mounting shell 5101. The top of the turntable 5102 passes through the mounting shell 5101 and is connected to a drive motor 5103 (Panasonic MINAS A6 series MSMF042L1U2M). A connecting rod 5104 is fixedly connected to the bottom of the turntable 5102. A fixing member 5105 is hinged to the bottom of the connecting rod 5104. The waterjet cutting head 2 is fixedly mounted on the bottom of the fixing member 5105. The turntable 5102 is driven by the drive motor 5103, which drives the waterjet cutting head 2 to achieve 360° continuous rotation.

[0023] The tilting assembly 52 includes a first hinge seat 5201, which is fixedly installed on the bottom of the turntable 5102. An electric push rod 5202 (model: Festo DSNU-25-80-PA) is hinged to the bottom of the first hinge seat 5201. A second hinge seat 5203 is fixedly connected to one end of the telescopic end of the electric push rod 5202. The second hinge seat 5203 is fixedly connected to the fixing member 5105 through a fixing block. The tilting assembly 52 drives the fixing member 5105 to swing around the hinge point through the linear telescopic extension of the electric push rod 5202, thereby realizing the tilt angle adjustment of the waterjet cutting head 2. The electric push rod 5202 has a built-in high-precision displacement sensor (resolution 0.01mm), which, combined with the CNC system, provides real-time feedback of the cutting angle data to ensure that the jet direction is aligned with the normal of the workpiece surface.

[0024] The drive motor 5103 is fixedly installed inside the mounting housing 5101. One end of the output shaft of the drive motor 5103 is fixedly connected to the top of the turntable 5102. The drive motor 5103 is a hollow shaft direct drive servo motor, which is coaxially connected to the turntable 5102.

[0025] The adjustment assembly includes two sets of first electric slide rails 301 (model HIWIN HGW25CCZAC), both sets of first electric slide rails 301 are fixedly installed on the top of the worktable 1, and the top of the two sets of first electric slide rails 301 are respectively slidably connected to first sliders 302. The top of the two sets of first sliders 302 are fixedly connected to support frames 303. The inner top of the support frame 303 is fixedly connected to a second electric slide rail 304 (model: THK SSR20XW1UU). The bottom of the second electric slide rail 304 is slidably connected to a second slider 305. The connecting plate 4 is fixedly installed on the bottom of the second slider 305. The electric slide rail adopts ball screw drive and is combined with closed-loop feedback of grating ruler to ensure the repeatability accuracy of the cutting path. The support frame 303 adopts a lightweight aluminum alloy truss structure, which reduces inertial load while ensuring rigidity.

[0026] Two sets of mounting plates 6 are symmetrically fixedly connected to the bottom of the workbench 1. Each of the two sets of mounting plates 6 is equipped with a clamping component 7 for positioning the slide bridge. The symmetrical layout of the clamping components 7 can simultaneously apply a balanced clamping force to both ends of the slide bridge to prevent the workpiece from shifting during processing.

[0027] The clamping assembly 7 includes a drive cylinder 701 (model: SMC CDQ2B20-100DCMZ). The drive cylinder 701 is fixedly installed on one side wall of the mounting plate 6. One end of the extension end of the drive cylinder 701 passes through the mounting plate 6 and is fixedly connected to a connecting block 702. The top of the connecting block 702 passes through the worktable 1 and is connected to a clamping plate 703. The drive cylinder 701 is a double-acting pneumatic-hydraulic booster cylinder, and the output force can be steplessly adjusted (range 500-2000N). The clamping force is controlled by a proportional valve to avoid damage to brittle materials (such as carbon fiber composite materials) due to overpressure. Both cylinders are equipped with encoders or displacement sensors. The PLC synchronously controls the servo valve through high-speed pulse output (such as 100kHz) to achieve closed-loop position control.

[0028] The top of the workbench 1 is provided with two sets of through slots 8 that are adapted to the connecting blocks 702. The two sets of connecting blocks 702 are slidably connected to the two sets of through slots 8 respectively. The sliding mating surfaces of the connecting blocks 702 and the through slots 8 are embedded with self-lubricating copper sleeves to reduce frictional resistance. The clamping surface of the clamping plate 703 is covered with a polyurethane anti-slip layer, which protects the workpiece surface and increases the coefficient of friction to ensure clamping stability.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
