Abstract
Description
Technical Field
[0001] This utility model relates to the field of engine manufacturing technology, specifically to a processing lifting platform for cylinder block inspection. Background Technology
[0002] Engine block gas tightness testing is a technical method to assess the presence of leaks by testing the sealing performance of the gas inside the cylinder block. This method uses pressure testing and pressure change analysis to determine the sealing performance of various cylinder block components (such as valves, piston rings, cylinder head gaskets, etc.), ensuring normal engine operation and reducing the risk of failure. Testing principle: It employs pressure change time series analysis and temperature change image set detection. By pressurizing the inside of the cylinder block and monitoring pressure changes, combined with temperature compensation, leak points are identified. If a poor seal exists, gas will leak from the gaps, causing a pressure drop, and the detection system can locate the coordinates of the leak.
[0003] For example, the publication number is CN222393731U, the publication date is January 24, 2025, and the title is "An Engine Cylinder Head Sealing Test Device". This device includes a frame with a worktable, a lateral moving mechanism, a side clamping sealing mechanism, a lifting mechanism, an upper sealing mechanism, a front sealing mechanism, a rear sealing mechanism, a plugging mechanism, and a leakage detection mechanism. All sealing mechanisms and the lifting mechanism in this invention are driven by an automatic telescopic structure, resulting in a high degree of automation and eliminating the need for manual operation. It achieves efficient airtightness testing of the engine cylinder head; the entire process is automated and requires no manual intervention; and each sealing mechanism is equipped with an airtight sealing ring between itself and the engine cylinder head, ensuring a good sealing effect. The entire device is equipped with a protective mesh cover for good safety.
[0004] In existing technology, the engine block is transported by a conveyor line to a testing station. Subsequently, a lifting mechanism raises the engine block, which is then inspected by a testing mechanism. However, because the lifting mechanism lacks a mechanism to limit engine movement, the engine becomes unstable during raising, causing it to wobble and resulting in scratches on the bottom of the engine block. Utility Model Content
[0005] The purpose of this invention is to provide a machining lifting platform for cylinder block inspection, so as to overcome the shortcomings of the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a machining lifting platform for cylinder block inspection, comprising:
[0007] A conveyor frame on which multiple conveyor rollers are rotatably connected;
[0008] The engine block abuts against each of the conveyor rollers;
[0009] The frame is located at the bottom of the conveyor frame;
[0010] The cylinder is mounted on the frame;
[0011] The limiting mechanism includes a support plate fixedly connected to the cylinder, and two limiting components are provided on the support plate;
[0012] The limiting assembly includes a lifting rod that is vertically slidably connected to a support plate, a rotating cylinder that is rotatably connected to the support plate, a connecting rod that is rotatably connected to the rotating cylinder, a vertical rod that is rotatably connected to the connecting rod, the vertical rod that is slidably connected to the support plate, and two limiting blocks that are fixedly connected to the vertical rod.
[0013] As the lifting rod descends vertically, it drives the rotating drum to rotate passively, thereby causing the two limit blocks to come into contact with the side wall of the engine cylinder.
[0014] Furthermore, an abutment rod is fixedly connected to the lifting rod, and an abutment groove is provided on the rotating drum, with the abutment rod slidingly abutting against the abutment groove.
[0015] Furthermore, a blind groove is provided on the support plate for the rotation of the rotating drum.
[0016] Furthermore, the support plate has a horizontal groove for the vertical rod to slide.
[0017] Furthermore, a fixed rod is fixedly connected inside the blind groove, a lifting rod is sleeved on the fixed rod, and an elastic element is provided between the lifting rod and the fixed rod.
[0018] Furthermore, the elastic element is a compression spring.
[0019] Compared with the prior art, the present invention provides a processing lifting platform for cylinder block inspection. By setting a limiting mechanism, under the power drive of the cylinder, during the process of the support plate rising, the lifting rod comes into contact with the engine cylinder block and slides vertically, driving the rotating drum to rotate passively, so as to pull one end of the connecting rod to move synchronously. The other end of the connecting rod drives the limiting block to move through the vertical rod, so that the limiting block limits the outer wall of the engine cylinder block, preventing the engine cylinder block from shaking and causing scratches during the lifting process.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0030] Please see Figure 1-7 This utility model provides a processing lifting platform for cylinder block inspection, comprising: a conveyor frame 1 on which multiple conveyor rollers 2 are rotatably connected; specifically, each conveyor roller 2 is connected to the others by a sprocket and a chain, and a drive motor is provided to drive one of the conveyor rollers 2 to rotate, which is prior art and will not be described in detail here; preferably, the multiple conveyor rollers 2 located at the middle position along the length direction of the conveyor frame 1 are in two sections; it is understood that by setting the conveyor rollers 2 in two sections, a lifting space is formed between the conveyor rollers 2, which facilitates the lifting of the limiting mechanism 6 by the power of the cylinder 5, so as to achieve the purpose of lifting the engine cylinder block 3; specifically, the width of the bearing plate 61 is smaller than the width of the above-mentioned lifting space.
[0031] Preferably, a baffle (such as a baffle plate) is fixedly connected to the conveyor frame 1. Figure 2The baffle is used to limit the engine cylinder block 3 during the conveying process. It can be understood that the baffle is only used to limit the engine cylinder block 3 during the conveying process, while the limiting mechanism 6 in this embodiment is used to limit the engine cylinder block 3 during the lifting process. The function of the baffle is to ensure that the engine cylinder block 3 does not deviate, so that the limiting mechanism 6 can limit the lifting process of the engine cylinder block 3 in the subsequent lifting process.
[0032] The engine cylinder block 3 abuts against each of the conveying rollers 2; the frame 4 is located at the bottom of the conveyor frame 1; the cylinder 5 is located on the frame 4; specifically, the output end of the cylinder 5 passes through and extends to the outside of the frame 4.
[0033] The limiting mechanism 6 includes a support plate 61 fixedly connected to the cylinder 5, and two limiting components are provided on the support plate 61. Specifically, the limiting components include a lifting rod 62 vertically slidably connected to the support plate 61. The lifting rod 62 abuts against the bottom of the engine cylinder block 3. It is understood that the engine cylinder block 3 has multiple cylinder holes, and the lifting rod 62 abuts against a solid position between two adjacent cylinder holes. A rotating cylinder 64 is rotatably connected to the support plate 61. The support plate 61 has a blind groove 611 for the rotating cylinder 64 to rotate. A connecting rod 65 is rotatably connected to the rotating cylinder 64. Specifically, the rotating cylinder 64 and the connecting rod 65 are connected by a crossbar, and the connection between the connecting rod 65 and the crossbar is... The contact point is located away from the axis of the rotating drum 64, i.e., eccentrically positioned; a vertical rod 66 is rotatably connected to the connecting rod 65, and the vertical rod 66 is slidably connected to the support plate 61; specifically, the support plate 61 has a horizontal groove 612 for sliding the vertical rod 66; two limiting blocks 67 are fixedly connected to the vertical rod 66; preferably, the limiting blocks 67 are arranged at right angles; during the vertical descent of the lifting rod 62, the rotating drum 64 is driven to rotate passively, thereby causing the two limiting blocks 67 to abut against the side wall of the engine cylinder block 3; specifically, an abutting rod 63 is fixedly connected to the lifting rod 62, and an abutting groove 641 is provided on the rotating drum 64, with the abutting rod 63 slidingly abutting against the abutting groove 641; more specifically, the abutting groove 641 is spirally formed.
[0034] Specifically, a fixed rod 68 is fixedly connected inside the blind groove 611, and a lifting rod 62 is sleeved on the fixed rod 68. An elastic element 69 is provided between the lifting rod 62 and the fixed rod 68; specifically, the elastic element 69 is a compression spring.
[0035] Working principle: When in use, the conveyor frame 1 transports the engine cylinder block 3 to the lifting space position through the rotation of the conveyor roller 2. It can be understood that at this time, the segmented conveyor roller 2 can still support the engine cylinder block 3.
[0036] Subsequently, cylinder 5 starts, driving the support plate 61 to rise. During its rise, the lifting rod 62 abuts against the bottom of the engine cylinder block 3, causing the lifting rod 62 to move vertically downward and compress the elastic element 69, causing the elastic element 69 to contract. At the same time, during the downward movement of the lifting rod 62, the abutting rod 63 and the abutting groove 641 abut against each other, causing the rotating drum 64 to rotate passively, thereby driving one end of the connecting rod 65 to move, causing the other end of the connecting rod 65 to pull the vertical rod 66 to slide in the horizontal groove 612, thereby causing the limiting block 67 to abut against the side wall of the engine cylinder block 3, completing the limiting of the engine cylinder block 3 and preventing the engine cylinder block 3 from shaking and causing scratches during the lifting process.
[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
