Description

Technical Field

[0001] This utility model relates to the field of engine manufacturing technology, and in particular to an engine cylinder block oil hole inspection tool. Background Technology

[0002] An engine is a machine that can convert other forms of energy into mechanical energy. The engine block is the core component of the engine. It is the structural foundation of the engine and a key component to ensure the efficient and stable operation of the engine. During the manufacturing process of the engine block, in order to ensure that the oil holes are unobstructed, the oil holes need to be inspected using testing tools after the engine block is manufactured.

[0003] As disclosed in Utility Model No. CN220473707U, an engine cylinder block oil hole detection fixture includes a fixture frame, a support module, and several fixing modules. The detection fixture can be fixed to the ground or a testing table via the fixture frame. The fixture frame is provided with an installation opening that can accommodate a vertically oriented engine cylinder block. One end of the support module is fixed to the fixture frame, and the other end of the support module can support the engine cylinder block at the installation opening. Each fixing module is installed around the periphery of the installation opening and fixedly connected to the fixture frame. When detecting oil holes in the engine cylinder block, the engine cylinder block can be placed vertically in the installation opening and supported by the end of the support module. The engine cylinder block can then be fixed by connecting it to the fixing modules, thereby increasing the exposure of the engine cylinder block and improving the light intensity of the oil holes in the engine cylinder block, thus avoiding false detection of oil holes in the engine cylinder block. However, once the engine block is fixed during the application of this technical solution, its position and angle cannot be adjusted. Since there are generally multiple engine blocks and the oil holes are located in different positions, there is a technical problem that the position of the detection fiber optic can not be quickly and stably adjusted to facilitate the inspection workers to carry out the engine oil hole inspection work efficiently. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides an engine cylinder block oil hole detection fixture, which can solve the technical problem that the position and angle of the engine cylinder block cannot be adjusted after it is fixed. Since there are generally multiple engine cylinder blocks and the oil holes are distributed in different positions, there is a problem that the position of the engine cylinder block and the detection fiber cannot be quickly and stably adjusted to facilitate the inspection workers to perform engine oil hole detection work efficiently.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an engine cylinder block oil hole detection fixture, including a base plate, a frame at the top of the base plate, a carrier at the middle position of the top of the base plate, a reserved groove at the top of the carrier, a light strip at the middle position of the bottom of the carrier, a fixed seat at the middle position of the front and rear ends of the bottom of the carrier, a rotating shaft at the middle position of the bottom of the carrier, stabilizing sliding sleeves on both sides of the bottom of the carrier, a stabilizing guide rail at the top of the base plate, a sliding rod at the top between the two sides inside the frame, a sliding seat at the middle position of the outside of the sliding rod, a detection optical fiber at the bottom of the sliding seat, and a fixing component on the inner side of the fixed seat.

[0006] As a preferred embodiment of this utility model, the bottom end of the rotating shaft and the top end of the base plate are movably connected at the middle position, and the slide block can slide outside the slide rod.

[0007] As a preferred embodiment of this utility model, the stabilizing guide rail is annular, the stabilizing sleeve is arc-shaped, the stabilizing sleeve is nested on the top of the stabilizing guide rail, and the stabilizing sleeve can slide on the top of the stabilizing guide rail.

[0008] As a preferred embodiment of this utility model, the reserved slot is circular and the reserved slots are arranged at equal intervals at the top of the inside of the carrier.

[0009] As a preferred embodiment of this utility model, the fixing component includes a stabilizing clamp plate, which is disposed on the inner side of the fixing base. A buffer pad is disposed on the inner side of the stabilizing clamp plate. An adjusting screw is disposed at the middle position of the outer side of the stabilizing clamp plate. A limiting rod is disposed on one side of the bottom of the outer side of the stabilizing clamp plate. A through hole is disposed at the middle position of the top of the inner side of the fixing base. A fastening screw sleeve is disposed on the outside of the adjusting screw.

[0010] In a preferred embodiment of this invention, the diameter of the adjusting screw is smaller than the inner diameter of the through hole, and one end of the adjusting screw penetrates the interior of the through hole.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By setting adjustment and positioning components between the top of the base plate and the bottom of the carrier and the top of the inner side of the frame, the carrier can be rotated around the rotation axis to adjust the placement angle of the engine cylinder block placed on it. At the same time, the stabilizing sleeve slides on the stabilizing guide rail to stabilize the carrier and the engine cylinder block. The horizontal position of the detection fiber can be adjusted by driving the slide block to slide outside the slide rod. This achieves the purpose of adjusting the positioning angle of the engine cylinder block and the position of the detection fiber to facilitate technicians to perform engine cylinder block oil hole detection operations, which helps to improve detection efficiency and reduce detection workload.

[0013] 2. By providing a fixing component on the inner side of the mounting base, the engine block to be tested is placed on top of the carrier during use, and the stabilizing clamp is pressed against both ends of the cylinder. Then, the fastening screw is tightened to press against the inner side of the mounting base. The adjusting screw can then be adjusted in the opposite direction to push the stabilizing clamp to hold and fix the engine block.

[0020] Example

[0021] Please refer to Figure 1-4 As shown, this utility model provides an engine block oil hole inspection fixture, including a base plate 1, a frame 7 at the top of the base plate 1, a carrier 2 at the middle of the top of the base plate 1, a circular pre-reserved groove 12 at the top of the carrier 2, and the pre-reserved grooves 12 are arranged at equal intervals at the top of the carrier 2. A light strip 15 is provided at the middle of the bottom of the carrier 2. A fixed seat 4 is provided at the middle of the front and rear ends of the bottom of the carrier 2. A rotating shaft 11 is provided at the middle of the bottom of the carrier 2. The bottom of the rotating shaft 11 is movably connected to the middle of the top of the base plate 1. During the inspection, the carrier 2 can be rotated around the rotating shaft 11 to adjust the placement angle of the engine block placed on it. Arc-shaped stabilizing sleeves 5 are provided on both sides of the bottom of the carrier 2. The top of the plate 1 is provided with a ring-shaped stabilizing guide rail 3. The stabilizing sleeve 5 is nested on the top of the stabilizing guide rail 3 and can slide on the top of the stabilizing guide rail 3. When the carrier 2 rotates, the stabilizing sleeve 5 slides on the stabilizing guide rail 3 to stabilize the carrier 2 and the engine block. The top of the frame 7 between the two sides is provided with a slide rod 8. The middle position of the slide rod 8 is provided with a slide seat 9. The slide seat 9 can slide outside the slide rod 8. The bottom of the slide seat 9 is provided with a detection fiber optic cable 10. By driving the slide seat 9 to slide outside the slide rod 8, the horizontal position of the detection fiber optic cable 10 can be adjusted. This achieves the purpose of adjusting the positioning angle of the engine block and the position of the detection fiber optic cable 10 to facilitate the technicians to perform engine block oil hole detection operations, which helps to improve detection efficiency and reduce detection workload.

[0022] When in use, the mounting frame 2 can be rotated around the rotating shaft 11 to adjust the placement angle of the engine cylinder block placed on it. At the same time, the stabilizing sleeve 5 slides on the stabilizing guide rail 3 to stabilize the mounting frame 2 and the engine cylinder block. The horizontal position of the detection fiber optic cable 10 can be adjusted by driving the sliding block 9 to slide outside the sliding rod 8.

[0023] As a further implementation of this embodiment, such as Figure 1-4As shown, a fixing component is provided on the inner side of the fixing base 4. The fixing component includes a stabilizing clamp 6, which is located on the inner side of the fixing base 4. A buffer pad 18 is provided on the inner side of the stabilizing clamp 6. An adjusting screw 14 is provided at the middle position on the outer side of the stabilizing clamp 6, and a fastening sleeve 16 is provided on the outer side of the adjusting screw 14. After placing the engine block to be tested on the top of the carrier 2, the stabilizing clamp 6 is pressed against both ends of the cylinder block, and the fastening sleeve 16 is tightened to press it against the inner side of the fixing base 4. The adjusting screw 14 can then be adjusted in the opposite direction to push the stabilizing clamp 6 to clamp and fix the engine block. At the same time, the buffer pad 18 can prevent the cylinder block from being clamped. To prevent excessive damage to the cylinder block, a limiting rod 13 is provided on one side of the bottom outer side of the stabilizing clamp 6. The limiting rod 13 prevents the stabilizing clamp 6 from deflecting and affecting the clamping effect. A through hole 17 is provided at the middle position of the top inner side of the fixing seat 4. The diameter of the adjusting screw 14 is smaller than the inner diameter of the through hole 17. One end of the adjusting screw 14 passes through the interior of the through hole 17. The through hole 17 is used to limit and stabilize the adjusting screw 14 during the forward and backward adjustment movement. This achieves the effect of convenient, quick, stable and safe clamping and fixing of the engine cylinder block to ensure the stable operation of oil hole detection. It is also applicable to engine cylinder blocks of different sizes.

[0024] When in use, place the engine block to be tested on the top of the carrier 2, and press the stabilizing clamp 6 against both ends of the cylinder block. Then tighten the fastening nut 16 to press it against the inside of the fixing seat 4. The adjusting screw 14 can be adjusted in the opposite direction to push the stabilizing clamp 6 to clamp and fix the engine block. At the same time, the buffer pad 18 can be used to avoid excessive clamping and damage to the cylinder block, and the adjusting screw 14 is limited and stabilized through the through hole 17.

[0025] Specific working principle:

[0026] When using the engine block oil hole inspection fixture, first place the engine block to be inspected on top of the carrier 2, aligning the cylinder block with the pre-drilled slot 12 to ensure exposure. Secure the stabilizing clamp 6 against both ends of the cylinder block, then tighten the fastening sleeve 16 to press it against the inside of the fixing seat 4. This allows the adjusting screw 14 to be reversed, pushing the stabilizing clamp 6 to hold and fix the engine block. The buffer pad 18 prevents excessive clamping and damage to the cylinder block. The adjusting screw 14 is then limited and stabilized through the through hole 17. Finally, turn on the light strip 15 to illuminate the cylinder. The light is directed into the engine cylinder, making the cylinder and oil holes brighter. At the same time, the inspector uses the optical fiber to probe the oil holes in the engine cylinder to ensure that the oil holes are unobstructed. During the inspection, the carrier 2 is rotated around the rotating shaft 11 to adjust the placement angle of the engine cylinder placed on it. Simultaneously, the stabilizing sleeve 5 slides on the stabilizing guide rail 3 to stabilize the carrier 2 and the engine cylinder. The horizontal position of the detection optical fiber 10 can be adjusted by moving the sliding block 9 outside the sliding rod 8, thus enabling quick and accurate detection of the engine cylinder oil holes.
