Description

Technical Field

[0001] This utility model belongs to the field of oil tank pad drilling technology, specifically an oil tank pad drilling fixture. Background Technology

[0002] In the fuel supply system of automobiles, construction machinery and other equipment, the fuel tank pad is a key structural component to ensure the stability and safety of the fuel tank installation. Its main function is to achieve the positioning support of the fuel tank by connecting with the frame or the main body of the equipment, so as to prevent the fuel tank from being displaced or damaged due to vibration and bumps during the operation of the equipment.

[0003] To achieve precise assembly of the fuel tank gasket with the vehicle frame and equipment body, the fuel tank gasket needs to be drilled to form uniformly sized assembly holes. The drilling process relies on specialized fixtures to ensure machining accuracy. Currently, the fixtures used in the industry for drilling fuel tank gaskets are mainly based on a fixed clamping design, typically including a base, locating pins, clamping devices, and drill bushing guide structures.

[0004] Currently, the fixtures used in the industry for drilling fuel tank gaskets mainly position the gaskets through a fixed clamping structure, and then work with a drilling machine to complete the drilling operation. However, existing fixtures lack a dynamic compensation mechanism for the contact state between the drill rod and the gasket, and cannot adjust the position of the gasket according to real-time changes during the processing. When drilling deep holes, the fixed fixture makes the gasket lack effective support and propulsion guidance, which may cause the gasket to undergo micro-deformation due to uneven force during the drilling process, further affecting the accuracy of the drilling position. In severe cases, it may even require rework or scrapping of the gasket, reducing production efficiency.

[0005] Therefore, a drilling fixture for fuel tank gaskets is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a fuel tank gasket drilling fixture, which can clamp and guide the fuel tank gasket during the drilling process, realize dynamic compensation between the drill and the gasket, greatly improve the working efficiency of drilling fuel tank gaskets, reduce the defect rate of fuel tank gasket production, and facilitate operation by workers.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drilling fixture for fuel tank gaskets, including a fixing block;

[0008] The surface of the fixing block is equipped with a clamping assembly, which includes a mounting bracket disposed on one side surface of the fixing block, a drive handle disposed on the surface of the mounting bracket, and a stabilizing plate, abutment rod, hydraulic rotary cylinder, connecting pipe, support rod, and drilling rod for clamping.

[0009] The surface of the fixing block is equipped with a disassembly and replacement assembly, which includes a threaded rod installed inside the mounting bracket, a nut disposed on one side surface of the fixing block, bolts for disassembly and replacement, and a mounting plate.

[0010] Preferably, the stabilizing plate is hinged to the upper surface of the mounting bracket, the stabilizing plate is hinged to the drive handle, the two support rods are symmetrically mounted on one side surface of the fixed block, the hydraulic rotary cylinder is mounted on one end of the two support rods, the two connecting pipes are respectively mounted on the inlet and outlet ends of the hydraulic rotary cylinder, the drilling rod is mounted on the output end of the hydraulic rotary cylinder, and one end of the drilling rod passes through the fixed block and extends to the other side of the fixed block. The abutment rod is disposed on the side surface of the drive handle near the fixed block.

[0011] Preferably, the abutting end of the abutting rod is equipped with an abutting joint.

[0012] Preferably, a friction sleeve is installed at the handle end of the drive handle.

[0013] Preferably, one end of the threaded rod passes through the fixing block and extends to the outside of the fixing block, and is threadedly connected to the nut.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1.

[0025] 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.

[0026] like Figures 1 to 5 As shown, this utility model provides a drilling fixture for fuel tank gaskets, including a fixing block 1;

[0027] A clamping assembly 2 is mounted on the surface of the fixing block 1. The clamping assembly 2 includes a mounting bracket 21 disposed on one side surface of the fixing block 1, a drive handle 23 disposed on the surface of the mounting bracket 21, and a stabilizing plate 24, an abutment rod 25, a hydraulic rotary cylinder 26, a connecting pipe 27, a support rod 28, and a drilling rod 29 for clamping.

[0028] The stabilizing plate 24 is hinged to the upper surface of the mounting bracket 21. The stabilizing plate 24 is hinged to the drive handle 23. Two support rods 28 are symmetrically installed on one side surface of the fixed block 1. The hydraulic rotary cylinder 26 is installed at one end of the two support rods 28. Two connecting pipes 27 are respectively installed at the inlet and outlet ends of the hydraulic rotary cylinder 26. The drilling rod 29 is installed at the output end of the hydraulic rotary cylinder 26, and one end of the drilling rod 29 passes through the fixed block 1 and extends to the other side of the fixed block 1. The abutment rod 25 is set on the side surface of the drive handle 23 near the fixed block 1. The coordinated design of the drive handle 23, the stabilizing plate 24 and the abutment rod 25 converts the rotation of the drive handle 23 into the linear motion of the abutment rod 25 pushing the oil tank pad, replacing the traditional fixed clamping structure. This realizes the active advancement of the pad according to the processing requirements during the drilling process, avoiding problems such as uneven force and micro-deformation when drilling deep holes due to the pad being fixed, and significantly improving drilling accuracy.

[0029] The abutting end of the abutting rod 25 is equipped with an abutting joint 22. The abutting joint 22 can be made of flexible or high-friction materials such as rubber or nylon. When the abutting rod 25 pushes the pad, it can avoid scratches and pressure damage caused by direct contact between the metal and the surface of the pad. It can also increase the friction between the abutting joint 22 and the pad through the high friction coefficient, prevent slippage between the pad and the abutting joint 22 during the pushing process, and ensure the effectiveness of the pushing action.

[0030] The handle end of the drive handle 23 is equipped with a friction sleeve. The friction sleeve increases the friction between the handle end and the operator's hand, avoiding the problem of handle slippage caused by hand sweat, oil, etc., and reducing the risk of operation error. At the same time, the friction sleeve can adopt an anti-slip texture design to further improve grip comfort, reduce hand fatigue caused by long-term operation, and optimize the human-computer interaction experience.

[0031] The surface of the fixing block 1 is equipped with a disassembly and replacement assembly 3, which includes a threaded rod 31 installed inside the mounting bracket 21, a nut 32 provided on one side surface of the fixing block 1, a bolt 33 for disassembly and replacement, and a mounting plate 34.

[0032] One end of the threaded rod 31 passes through the fixed block 1 and extends to the outside of the fixed block 1, and is threadedly connected to the nut 32. This breaks the limitations of the traditional integrated design of the fixture. The position of the mounting bracket 21 can be adjusted or the mounting bracket 21 can be disassembled directly through the threaded rod 31 and the nut 32. The bolt 33 and the mounting plate 34 can be used to quickly disassemble and replace components such as the abutment rod 25, so that the fixture can be adapted to the processing of oil tank pads of different specifications and thicknesses, thereby improving the versatility and adaptability of the equipment.

[0033] Mounting plate 34 is inserted into the surface of drive handle 23 and is connected to abutment rod 25, making the assembly of mounting plate 34 and drive handle 23 more convenient.

[0034] Bolt 33 is threaded into a threaded hole on the surface of mounting plate 34, and one end of bolt 33 passes through mounting plate 34 and is threaded into a threaded hole on the surface of drive handle 23. The threaded locking of bolt 33 is added to the plug-in structure to prevent the mounting plate 34 and drive handle 23 from loosening or falling off when the clamp is working (drive handle 23 rotates and vibrates), ensuring the effective transmission of power when the abutment rod 25 is pushed forward, and further ensuring the stability of the pushing action.

[0035] Among them, the hydraulic rotary cylinder 26 and the connecting pipe 27 are existing technologies, and their working principle is a well-known technology. The appropriate model is selected according to the actual use.

[0036] Working principle and process: Place the oil tank pad to be drilled in the preset processing area of ​​the fixed block 1, and ensure that the position of the pad to be drilled is aligned with the axis of the drilling rod 29, so as to lay the benchmark for subsequent precise drilling.

[0037] The operator holds the friction sleeve end of the drive handle 23 and then rotates the drive handle 23. Since one end of the stabilizing plate 24 is hinged to the upper surface of the mounting bracket 21 and the other end is hinged to the drive handle 23, the rotation of the drive handle 23 will drive the stabilizing plate 24 to rotate synchronously around the hinge point. At the same time, the abutment rod 25 on one side of the drive handle 23 gradually approaches the fuel tank pad as the handle moves. The drive handle 23 is continuously rotated until the abutment joint 22 at the end of the abutment rod 25 is tightly fitted with the side of the fuel tank pad. By adjusting the rotation angle of the drive handle 23, the support of the stabilizing plate 24 is used to ensure that the pressure of the abutment rod 25 is uniform, avoiding uneven force on the pad and causing initial deformation. Finally, the fuel tank pad is stably clamped on the surface of the fixing block 1, completing the positioning and fixing.

[0038] By controlling the hydraulic system, pressurized oil enters the hydraulic rotary cylinder 26 through the connecting pipe 27. The input end of the connecting pipe 27 is connected to the external control hydraulic system (the support rod 28 provides stable support for the hydraulic rotary cylinder 26 to prevent it from shaking during operation). The hydraulic rotary cylinder 26 starts under hydraulic drive, and the output end drives the drilling rod 29 to rotate at high speed.

[0039] As the drill rod 29 cuts the pad, the drilling depth gradually increases. At this point, the drive handle 23 needs to be rotated slowly according to the drilling depth. The abutment rod 25 continuously drives the pad towards the drill rod 29, ensuring that the drill rod 29 always maintains contact with the cutting surface of the pad and continues to complete the cutting and drilling. During the advance, the rotation force of the drive handle 23 needs to be adjusted according to the drilling load to avoid the drill rod 29 spinning freely due to insufficient advance or excessive advance increasing the drilling resistance. Until the drill rod 29 completely penetrates the oil tank pad (reaching the preset drilling depth), the hydraulic rotary cylinder 26 is closed to stop the drill rod 29 from rotating.

[0040] Reverse rotation of the drive handle 23 drives the abutment rod 25 and the abutment joint 22 away from the oil tank pad, releasing the pushing and clamping state; then the drilled pad is removed from the processing area of ​​the fixed block 1. If the pad is pressed against the limiting surface of the fixed block 1 due to pushing, the pad can be gently pushed away from the limiting surface to ensure smooth removal and complete the single processing.

[0041] When it is necessary to replace the abutment rod 25 that is adapted to different specifications of pads (such as adjusting the size of the abutment joint 22), or when the friction sleeve of the drive handle 23 is worn, first unscrew the bolt 33 on the surface of the mounting plate 34 so that the bolt 33 is removed from the threaded hole of the mounting plate 34 and the drive handle 23, and then pull the mounting plate 34 out of the surface of the drive handle 23, and the abutment rod 25 connected to it can be removed for replacement.

[0042] If it is necessary to adjust the position of the mounting bracket 21 to accommodate the advance stroke of pads of different lengths, or to disassemble the mounting bracket 21, the nut 32 can be loosened, the mounting bracket 21 can be moved to a suitable position along the axis of the threaded rod 31, or a new mounting bracket 21 can be directly replaced, and then the nut 32 can be tightened again to improve the adaptability of the fixture to the processing of oil tank pads of different specifications.

[0043] 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.
