Description

Technical Field

[0001] The invention belongs to the technical field of automobile production, in particular to a device for detecting the machining surface of a compressor housing of an automobile engine. Background Art

[0002] Turbochargers are generally used in automobile engines and aircraft engines. With the development of society, the use of automobiles is becoming more and more frequent, so the demand for turbochargers is also increasing. During the production of existing turbochargers, the threaded outer shell of the turbocharger is produced by casting, and then the internal rotor is assembled into a complete turbocharger. Since the outer shell of the turbocharger is relatively rough after casting, further processing work is required, that is, the outer shell of the turbocharger needs to be cut and polished.

[0003] The casing of a turbocharger is usually machined using a milling machine. Since the casing of a turbocharger is asymmetrical in shape, when the milling machine clamps the casing of the turbocharger for rotation, the casing is likely to rotate unstably under the action of centrifugal force. Therefore, an instrument is required to inspect the inside of the casing after processing to ensure that there are no defects or uneven areas. However, when inspectors use scanners for inspection, it is easy to miss inspections, and the inspection time is long, which is very inconvenient, so the inspection tools need to be improved. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting the following technical solutions: a device for detecting the machining surface of a compressor housing of an automobile engine, comprising a machining blank housing, a detection device is arranged at the axis center of the machining blank housing, a support plate is arranged at the bottom of the machining blank housing, and an axis limit device is arranged at the axis center of the inner cavity of the support plate;

[0006] The cluster detector includes an outer disk shell, which is formed by stacking multiple groups of outer disk shells and internal optical components so as to obtain multiple groups of detection data during one movement, thereby eliminating the interference of errors. A processing unit is fixedly connected to the axis of the inner cavity of the outer disk shell, and the outer surface of the processing unit is evenly provided with distance-adjusting rods, which are segmented hollow rods. The inner cavity of the processing unit is evenly provided with detection rods, and the end of the detection rod away from the processing unit is fixedly connected with a scanning lens, and the middle part of the outer surface of the detection rod is fixedly connected with a fixed rod sleeve, and the side of the outer surface of the fixed rod sleeve away from the distance-adjusting rod is fixedly connected with a compression gasket. Since the end of the distance-adjusting rod is inserted into the compression gasket, and the compression gasket and the inner wall of the outer disk shell form an enclosed space, when the distance-adjusting rod pressurizes or depressurizes the inside of the compression gasket, the compression gasket can drive the detection rod to slide through the fixed rod sleeve.

[0007] Furthermore, the guide slide cylinder includes a thin cylinder shell, the top of the inner wall of the thin cylinder shell is slidably connected to a guide slip ring, the lower surface of the guide slip ring is slidably connected to a traction bottom cylinder through a lower pull rod, and active rollers are symmetrically arranged on both sides of the inner wall of the guide slip ring. The axis of the active roller is rotated by controlling the motors on both sides, and then rotates around the middle of the inner wall of the guide slip ring with the outer surface of the motor as the connection point.

The end of the detection rod away from the inner wall of the processing shell is slidably connected to the inner wall of the processing unit through the through-hole, and the inner cavity of the detection rod is fixedly connected to the inner cavity of the processing unit through the connecting wire, the end of the distance adjustment rod away from the processing unit extends to the inside of the compression washer, and the side of the compression washer away from the processing unit is fixedly connected to the inner wall of the outer disk shell. The number of the outer disk shells is four, the end of the distance adjustment rod away from the fixed rod sleeve is fixedly connected to the outer surface of the processing unit, the upper and lower ends of the processing unit extend to the outside of the outer disk shell, and the top of the signal processing cylinder is fixedly connected to the ceiling.

[0009] Furthermore, the support plate includes a load-bearing plate, a bunching disk is fixedly connected to the axis of the inner cavity of the load-bearing plate, an inverted motor is evenly arranged on the upper surface of the bunching disk, an embedded rotating wheel is fixedly connected to the bottom end of the inverted motor output shaft, a light receiving ring is arranged at the axis of the inner wall of the load-bearing plate, and a pressurizing outer ring is sleeved on the outer surface of the light receiving ring.

[0010] Furthermore, the axis limiting device includes a rotating ring shell, the lower surface of the rotating ring shell is evenly provided with annular slide rails, and the annular slide rails are evenly provided with penetrating air vents, which are in contact with and connected to the pressurized outer ring below, and the top of the inner wall of the rotating ring shell is evenly provided with an eccentric outer shell, and the inner wall of the eccentric outer shell is slidably connected with a solid push block on the side close to the processing blank shell, and the end of the solid push block away from the processing blank shell is fixedly connected with a sliding piston, and the inner cavity of the solid push block is evenly provided with auxiliary rolling balls on the side close to the processing blank shell, and the outer surface of the solid push block is sleeved with a vertical lighting lamp on the side close to the processing blank shell, and the light receiving ring can receive light from the vertical lighting lamp directly above, and draw a corresponding arc trajectory through the internal photosensitive equipment according to the movement trajectory of the vertical lighting lamp.

[0011] Furthermore, the lower surface of the rotating ring shell is rotatably connected to the upper surface of the pressurized outer ring through an annular slide rail, and the outer surface of the rotating ring shell is rotatably connected to the outer surface of the embedded runner, the side of the solid push block close to the processing blank shell is mutually squeezed with the outer surface of the processing blank shell through an auxiliary rolling ball, the top of the eccentric shell extends to the outside of the rotating ring shell, and the bottom of the eccentric shell is fixedly connected to the top of the inner wall of the rotating ring shell. The outer surface of the sliding piston is slidably connected to the inner wall of the eccentric shell, the outer surface of the solid push block is slidably connected to the upper part of the inner wall of the rotating ring shell through a spring washer, and the axis of the bottom of the processing blank shell is plugged into the axis of the clustering disk.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device can perform outer surface scanning on the inner wall of the milled inner wall of the processed blank shell by rotating and pushing the stacked cluster detectors downward, thereby detecting unqualified parts of the inner wall of the processed blank shell instead of the human eye to prevent the production of defective products. Since inspectors are prone to missed inspections and blind spots when using general scanners for inspection, the cluster detector of the device scans while pushing downward to ensure that there are no blind spots in the scanning part of the inner wall, and the systematic inspection work is more convenient, so it is more suitable for production needs.

[0014] 2. The lens used to scan the inner wall can be moved by the distance adjustment rod during movement, so that the lens and the current inner wall of the blank shell are kept at a relatively close distance, making the image scanned by the lens clearer and achieving a controllable zoom effect. The retractable feature of the detection rod allows the cluster detector to pass through the narrower inner wall of the blank shell, thereby avoiding the problem of the detection rod being stuck with the inner wall of the processed blank shell and unable to move, thereby improving the flexibility of the device.

[0015] 3. In order to prevent the thin connecting rod from slipping and causing the cluster detector to loosen and become difficult to control, the friction between the active roller and the thin connecting rod needs to be large enough. The thin connecting rod will rotate with the cluster detector, so the bottom end of the thin connecting rod will drive the detection rod to rotate around the guide slip ring under the action of friction. The traction bottom cylinder can drive the guide slip ring to slide down through the pull rod, so that the active roller can slide down synchronously with the thin connecting rod. After the thin connecting rod is fully inserted into the thin cylinder shell, the active roller clamps the thin connecting rod in the middle position, thereby making the thin connecting rod more stable.

[0016] 4. When the detection device is working, the axial limit device of the device can detect whether the blank shell is stably limited at the axial position by rotating in close proximity to the blank shell from the outside, thereby ensuring that the internal detection device will not rotate around the inner wall of the blank shell in an eccentric manner, causing the cluster detector to easily collide with the inner wall of the blank shell.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0026] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a processing surface detection device for a compressor housing of an automobile engine, comprising a processing blank housing 1, a detection device 2 is arranged at the axis center of the processing blank housing 1, a support plate 3 is arranged at the bottom of the processing blank housing 1, and an axis limit device 4 is arranged at the axis center of the inner cavity of the support plate 3;

[0027] The detection device 2 includes a signal processing cylinder 21, a transfer extension arm 22 is fixedly connected to the axis of the lower surface of the signal processing cylinder 21, a photosensitive component 23 is arranged at the lower part of the outer surface of the transfer extension arm 22, a cluster detector 24 is rotatably connected to the axis of the bottom of the transfer extension arm 22, and the bottom of the cluster detector 24 is slidably connected to a guide slide 26 through a thin connecting rod 25, and the thin connecting rod 25 is inserted into the interior of the guide slide 26, and then the cluster detector 24 is driven to slide downward through the guide slide 26;

[0028] The cluster detector 24 includes an outer disk shell 241. The cluster detector 24 is formed by stacking multiple sets of outer disk shells 241 and internal optical components so as to obtain multiple sets of detection data in one movement process, thereby eliminating the interference of errors. The processing unit 242 is fixedly connected to the axis of the inner cavity of the outer disk shell 241. The outer surface of the processing unit 242 is evenly provided with a pitch rod 247. The pitch rod 247 is a segmented hollow rod. The inner cavity of the processing unit 242 is evenly provided with a detection rod 243. The end of the detection rod 243 away from the processing unit 242 is fixedly connected to the outer surface of the processing unit 242. A scanning lens 244 is fixedly connected, a fixed rod sleeve 245 is fixedly connected to the middle of the outer surface of the detection rod 243, and a compression gasket 246 is fixedly connected to the side of the outer surface of the fixed rod sleeve 245 away from the distance adjusting rod 247. Since the end of the distance adjusting rod 247 is inserted into the compression gasket 246, and the compression gasket 246 and the inner wall of the outer disk shell 241 form a closed space, when the distance adjusting rod 247 pressurizes or depressurizes the inside of the compression gasket 246, the compression gasket 246 can drive the detection rod 243 to slide through the fixed rod sleeve 245.

[0029] The guide slide 26 includes a thin cylinder shell 261, the top of the inner wall of the thin cylinder shell 261 is slidably connected to a guide slip ring 262, the lower surface of the guide slip ring 262 is slidably connected to a traction bottom cylinder 265 through a lower pull rod 264, and active rollers 263 are symmetrically arranged on both sides of the inner wall of the guide slip ring 262. The axis of the active roller 263 is rotated by the control of motors on both sides, and then rotates around the middle of the inner wall of the guide slip ring 262 with the outer surface of the motor as the connection point.

[0030] The bottom end of the thin connecting rod 25 extends to the axis of the inner wall of the thin cylindrical shell 261, the outer surface of the thin connecting rod 25 is rollingly connected to the middle of the outer surface of the active roller 263, both sides of the outer surface of the active roller 263 are rotationally connected to the inner wall of the guide slip ring 262 through the bent connecting rod, and the bottom of the traction bottom cylinder 265 is fixedly connected to the bottom of the inner wall of the thin cylindrical shell 261. The end of the detection rod 243 away from the inner wall of the processing blank shell 1 is slidably connected to the inner wall of the processing unit 242 through the through hole, and the inner cavity of the detection rod 243 is fixedly connected to the inner cavity of the processing unit 242 through the connecting wire, and the end of the pitch adjustment rod 247 away from the processing unit 242 extends to the inside of the compression washer 246, and the side of the compression washer 246 away from the processing unit 242 is fixedly connected to the inner wall of the outer disk shell 241. There are four outer disk shells 241, and one end of the pitch adjusting rod 247 away from the fixed rod sleeve 245 is fixedly connected to the outer surface of the processing unit 242. The upper and lower ends of the processing unit 242 extend to the outside of the outer disk shell 241, and the top of the signal processing tube 21 is fixedly connected to the ceiling.

[0031] When using the device to detect the outer surface smoothness of the processed blank shell 1 after milling, the axis center of the bottom end of the processed blank shell 1 is docked with the axis center of the axis limit device 4. At this time, the exhaust pipe on the side of the blank shell is inserted on the outer surface of the support plate 3. Then, the detection device 2 directly above is slowly pushed downward, and the thin connecting rod 25 is inserted into the interior of the guide slide 26 to complete the docking work. At this time, the preparation work is completed.

[0032] During operation, the transfer extension arm 22 twists the cluster detectors 24 connected in series through the thin connecting rod 25. At this time, the rotating outer disk shell 241 scans and detects the inner wall of the processed blank shell 1 through the scanning lenses 244 on all sides. After scanning for several circles to ensure that there are no dead angles, the guide slide 26 slowly pulls the cluster detector 24 downward through the guide slide 26, so that the outer disk shell 241 scans the inner wall of the processed blank shell 1 from top to bottom to realize the detection work.

[0033] As the cluster detector 24 moves, the shape of the inner wall of the processed blank shell 1 that it scans will change. Therefore, when it is located at the upper position of the processed blank shell 1, the distance adjustment rod 247 can push the detection rod 243 further outward, so that the distance between the scanning lens 244 and the inner wall of the processed blank shell 1 is closer, and the collected image is clearer. As the cluster detector 24 descends, the scanned inner wall of the processed blank shell 1 also shrinks. At this time, the detection rod 243 is retracted into the interior of the outer disk shell 241 to prevent the detection rod 243 from being stuck with the inner wall of the processed blank shell 1, resulting in the problem that the cluster detector 24 cannot move down to work normally.

[0034] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of the first embodiment, the support plate 3 includes a load-bearing plate 31, a bunching disk 32 is fixedly connected to the axis of the inner cavity of the load-bearing plate 31, an inverted motor 33 is evenly arranged on the upper surface of the bunching disk 32, an embedded rotating wheel 34 is fixedly connected to the bottom end of the output shaft of the inverted motor 33, a light receiving ring 36 is arranged at the axis of the inner wall of the load-bearing plate 31, and a pressurizing outer ring 35 is sleeved on the outer surface of the light receiving ring 36.

[0035] The axis limiting device 4 includes a rotating ring shell 41, and an annular slide rail 42 is evenly provided on the lower surface of the rotating ring shell 41, and the annular slide rail 42 is evenly provided with a penetrating vent, which is in contact with and connected to the pressurized outer ring 35 below. An eccentric shell 43 is evenly provided on the top of the inner wall of the rotating ring shell 41. A solid push block 45 is slidably connected to the side of the inner wall of the eccentric shell 43 close to the processing blank shell 1. A sliding piston 44 is fixedly connected to the end of the solid push block 45 away from the processing blank shell 1. Auxiliary rolling balls 46 are evenly provided on the side of the inner cavity of the solid push block 45 close to the processing blank shell 1. A vertical lighting lamp 47 is sleeved on the side of the outer surface of the solid push block 45 close to the processing blank shell 1. The light receiving ring 36 can receive the light emitted by the vertical lighting lamp 47 directly above, and draw a corresponding arc trajectory through the internal photosensitive equipment according to the movement trajectory of the vertical lighting lamp 47.

[0036] The lower surface of the rotating ring shell 41 is rotatably connected to the upper surface of the pressurizing outer ring 35 through the annular slide rail 42, and the outer surface of the rotating ring shell 41 is rotatably connected to the outer surface of the embedded runner 34. The side of the solid push block 45 close to the processing blank shell 1 is mutually squeezed with the outer surface of the processing blank shell 1 through the auxiliary rolling ball 46. The top of the eccentric shell 43 extends to the outside of the rotating ring shell 41, and the bottom of the eccentric shell 43 is fixedly connected to the top of the inner wall of the rotating ring shell 41. The outer surface of the sliding piston 44 is slidably connected to the inner wall of the eccentric shell 43, and the outer surface of the solid push block 45 is slidably connected to the upper part of the inner wall of the rotating ring shell 41 through a spring washer. The axis of the bottom of the processing blank shell 1 is plugged into the axis of the clustering disk 32.

[0037] The concave active rollers 263 on both sides pull the cluster detector 24 downward by rotating the thin connecting rod 25. In order to prevent slipping, the friction between the active roller 263 and the thin connecting rod 25 needs to be large enough, and the thin connecting rod 25 will rotate with the cluster detector 24, so the bottom end of the thin connecting rod 25 will drive the detection rod 243 to rotate around the guide slip ring 262 under the action of friction, and the traction bottom cylinder 265 can drive the guide slip ring 262 to slide down through the lower pull rod 264, so that the active roller 263 can slide down synchronously with the thin connecting rod 25. After the thin connecting rod 25 is fully inserted into the thin cylinder shell 261, the active roller 263 clamps the thin connecting rod 25 in the middle position, thereby making the thin connecting rod 25 more stable.

[0038] After the bottom end of the processed blank shell 1 is docked with the axis of the clustering disc 32, the axis limit device 4 will detect whether the processed blank shell 1 has a deviation problem due to inaccurate docking. After the lower pressurized outer ring 35 pressurizes the inside of the rotating ring shell 41 through the open annular slide rail 42, each solid push block 45 will be pushed toward the axis of the bottom of the outer surface of the processed blank shell 1 due to the thrust of the sliding piston 44, and finally squeezed against the bottom of the outer surface of the processed blank shell 1 through the auxiliary rolling ball 46. Then, the inverted motor 33 drives the rotating ring shell 41 to rotate around the processed blank shell 1 by rotating the embedded rotating wheel 34;

[0039] If the bottom of the processed blank shell 1 is perfectly butted against the axis of the clustering disc 32, the solid push block 45 which has been stretched to a fixed length will not change in length due to the extrusion of the blank shell during rotation;

[0040] If the bottom of the processed blank shell 1 is eccentrically docked with the axis of the clustering disk 32, the solid push block 45 that has been stretched to a fixed length will change in length during rotation due to the squeezing of the blank shell and the pressurization of the sliding piston 44. At this time, the trajectory of the vertical lighting lamp 47 sweeping across the light receiving ring 36 is not a perfect circle. According to the eccentric position of the circle on the light receiving ring 36, the misalignment direction of the processed blank shell 1 is judged, and trimming and adjustment work is performed to ensure that the processed blank shell 1 is successfully docked with the clustering disk 32.

[0041] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
