[0002] In the engineering field, gantry milling often requires the use of fixtures to fix and position the workpiece to ensure the stability and accuracy of the workpiece during the processing. For the gantry milling of the hydraulic cylinder seat, the support structure of some fixtures is not stable enough to effectively hold the hydraulic cylinder seat, which can easily cause vibration and instability during the processing, affecting the processing quality; some fixtures require a long time to install and adjust, which increases the processing preparation time and reduces the processing efficiency. Utility Model Content
[0003] The utility model aims to provide a gantry milling fixture and a gantry milling machine for a hydraulic cylinder seat which can effectively improve the processing accuracy, stability and processing efficiency.
[0004] A gantry milling tooling fixture for a hydraulic cylinder seat is installed on a workbench and includes a positioning tooling and a supporting tooling. The positioning tooling is used to position the hydraulic cylinder seat, and the supporting tooling is used to tighten the hydraulic cylinder seat. The supporting tooling includes a fixed base and a supporting plate. One side of the supporting plate can abut against the hydraulic cylinder seat, and the other side can abut against the fixed base. The fixed base and the support plate are connected by fasteners.
[0005] In the above scheme, the positioning tooling can ensure that the hydraulic cylinder seat will not shake in the vertical direction, and the supporting tooling can effectively prevent the hydraulic cylinder seat from moving horizontally during the processing through the structure of the fixed base and the support plate, thereby improving the processing accuracy; after the hydraulic cylinder seat is moved to the workbench, the fixed base can be moved to a suitable position first, and then the support plate can be placed between the hydraulic cylinder seat and the fixed base, and one side of the support plate can be abutted against the hydraulic cylinder seat and the other side can be abutted against the fixed base, and then the base and the support plate can be locked and fixed by fasteners, and then the positioning tooling can be installed. The design of the supporting tooling and the positioning tooling can firmly tighten the hydraulic cylinder seat so that it can be firmly fixed on the workbench, which improves the stability during processing and reduces the influence of vibration and unstable factors during processing; the design of the tooling fixture enables the hydraulic cylinder seat to be fixed and limited quickly and accurately, saving adjustment and installation time and improving processing efficiency.
[0006] Furthermore, the bottom of the fixed base is T-shaped, and the fixed base can be embedded in the T-shaped groove of the workbench.
[0007] In the above scheme, the fixed base at the bottom of the T-shape can be better embedded in the T-slot of the workbench, so that the fixation of the supporting tooling on the workbench is more firmly and stably, reducing the possibility of movement or shaking during processing, improving the stability and accuracy of processing, and also simplifying the installation steps of the supporting tooling on the workbench, making the installation faster and more convenient, saving adjustment and installation time, and improving work efficiency.
[0008] Furthermore, the support plate includes a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are connected in a V shape, and a plurality of connecting holes are formed on the first connecting plate and the second connecting plate.
[0009] In the above scheme, the first connecting plate and the second connecting plate are connected in a V-shape, which increases the stability of the support plate, enables the hydraulic cylinder seat to be better tightened during the processing, and improves the stability and accuracy of the processing. Multiple connecting holes are provided on the first connecting plate and the second connecting plate. The connecting holes can be selected according to the specific installation situation to make the connection between the support plate and the fixed base more flexible.
[0010] Furthermore, the first connecting plate and the second connecting plate are integrally formed.
[0011] In the above scheme, the one-piece connecting plate structure is more solid, reduces the weak points of the connection, improves the overall strength and stability of the support plate, can better withstand pressure and vibration during processing, and ensures the stability and accuracy of processing. Since there are no splicing or connections, the one-piece support plate reduces the possibility of failure points and looseness, increases the reliability and durability of the support tooling, and reduces the frequency of maintenance and replacement.
[0012] Furthermore, the positioning tooling includes a pressure block, a positioning block and a tightening bolt. The positioning block is fixed on the workbench, one end of the pressure plate is connected to the positioning block, and the other end is pressed on the hydraulic cylinder seat. The tightening bolt passes through the pressure block and extends into the T-slot of the workbench.
[0013] In the above scheme, the positioning block is fixed on the workbench, and there is a step on the hydraulic cylinder seat. One end of the pressure block is connected to the positioning block, and the other end is pressed on the step position of the hydraulic cylinder seat. The tightening bolt passes through the pressure block and extends into the T-slot of the workbench, so that the pressure block can press the hydraulic cylinder seat. This can avoid the vibration of the gantry milling machine during processing, causing the hydraulic cylinder seat to shift and cause errors, thereby ensuring the stability and accuracy of the processing.
[0014] Furthermore, the pressing block is provided with an oblong hole.
[0015] In the above scheme, the oblong hole on the pressure block is for facilitating the installation of the tightening bolt. Since the tightening bolt needs to extend into the T-slot of the workbench to ensure the overall stability, an oblong hole is provided on the pressure block to facilitate the operator to flexibly tighten the tightening bolt according to the installation position of the hydraulic cylinder seat on site.
[0016] Furthermore, the positioning tool also includes a cushion block, which can be installed on the positioning block and connected to the lower part of the pressing block.
[0017] In the above scheme, the pad is installed on the positioning block and connected to the pressing block. The height of different pads can be changed to adapt to workpieces of different heights or unevenness, thereby ensuring the stable positioning of the workpiece and improving the processing accuracy and quality. The design of adding pads increases the flexibility and applicability of the positioning tooling, enabling it to better adapt to workpieces of different sizes or shapes, and improving the versatility and efficiency of the tooling fixture.
[0018] Furthermore, a locking nut is sleeved on the tightening bolt.
[0019] In the above scheme, the anti-loosening nut can effectively prevent the tightening bolt from loosening under vibration or load, maintain the stability of the tooling fixture, and thus ensure the safety and precision during the processing. The anti-loosening nut can also reduce the wear of the threads on the tightening bolt, extend the service life of the tightening bolt, reduce maintenance costs, and improve the reliability and durability of the equipment.
[0020] A gantry milling machine comprises a workbench and a gantry milling fixture for a hydraulic cylinder seat as described in any one of the above schemes, wherein the workbench is provided with a plurality of T-slots, and the bottom of the fixed base can be snapped into the T-slots.
[0021] In the above scheme, by clamping the bottom of the fixed base into the T-slot on the workbench, a firm connection between the fixture and the workbench is ensured, the stability of the entire gantry milling machine is improved, and the processing process is made smoother and more reliable. Multiple T-slots are arranged on the workbench so that the fixed base can be clamped at different positions, thereby meeting the needs of processing workpieces of different sizes and enhancing the applicability and flexibility of the gantry milling machine.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the bottom of the fixed base 31 is T-shaped, and the fixed base 31 can be embedded in the T-slot 4 of the workbench 1. The fixed base 31 with a T-shaped bottom can be better embedded in the T-slot 4 of the workbench 1, so that the fixing of the supporting tool 3 on the workbench 1 is more firmly and stably reduced, the possibility of movement or shaking during the processing is reduced, the stability and accuracy of the processing are improved, and the installation steps of the supporting tool 3 on the workbench 1 are simplified, making the installation faster and more convenient, saving the adjustment and installation time, and improving the work efficiency.
