Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to a positioning device for an engine detection instrument. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The term engine can be applied to both power generation devices and the entire machine including the power device.

[0003] However, there are some problems with the prior art: during the production process of the engine casing, it is necessary to inspect the appearance of the engine casing to prevent cracks, flaws and other problems in the engine casing that affect the use of the engine. However, during the appearance inspection of the engine casing, the engine casing is generally fixed and then subjected to appearance inspection, or is directly placed for appearance inspection. However, this inspection method can only perform appearance inspection on one side. If the other side of the engine casing is to be inspected, it needs to be disassembled, turned over and re-fixed. The whole process is relatively cumbersome, which affects the inspection efficiency of the engine casing. At the same time, the fixing and clamping style is single, and can only be clamped and inspected for the same engine. When replacing engines of different sizes, the corresponding fixtures need to be replaced for clamping and fixing, which can easily increase the production cost of the enterprise. Therefore, we propose a positioning device for an engine detection instrument. Utility Model Content

[0029] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0030] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 5As shown, a positioning device for an engine detection instrument provided by an embodiment of the utility model comprises a base 1, wherein two groups of guide rails 2 are arranged on the upper surface of the base 1, and the two groups of guide rails 2 are slidably connected to two groups of slide plates 3 together, and a first driving assembly 4 is arranged on the upper surface of the base 1, and the first driving assembly 4 is transmission-connected to the two groups of slide plates 3, and a first fixing plate 5 is arranged on the upper surface of the slide plate 3, and a transverse plate 6 is slidably connected to one side of the first fixing plate 5, and a placement plate 10 is fixedly installed on the upper surface of the first fixing plate 5, and a second driving assembly 7 is arranged on the upper surface of the placement plate 10, and the second driving assembly 7 is transmission-connected to the transverse plate 6, and a vertical plate 11 is fixedly installed on the upper surface of the transverse plate 6, and a rotating shaft 12 is rotationally connected to one side of the vertical plate 11, and a third driving assembly 8 is arranged on the upper surface of one group of transverse plates 6, and the third driving assembly 8 is transmission-connected to the rotating shaft 12, and a clamping assembly 9 is fixedly installed on one end of the rotating shaft 12. In the production process of the engine, it is necessary to perform appearance inspection on the produced engine to prevent cracks, defects and other problems in the engine casing from affecting the normal use of the engine. However, in the process of engine appearance inspection, the engine is generally inspected. Fix it and then perform an appearance inspection on it, or directly place the engine for appearance inspection, but this inspection can only perform an appearance inspection on one side. If you want to inspect the other side of the engine, you need to disassemble the engine casing, turn it over and re-fix it. The whole process is relatively cumbersome, which affects the efficiency of the engine casing inspection work. At the same time, the fixing and clamping style is single, and can only be clamped and inspected for one engine. When replacing engines of different sizes, it is necessary to replace the corresponding clamps for clamping and fixing, which is easy to increase the production cost of the enterprise. Therefore, the two groups of skateboards 3 are moved relative to or away from each other by the first drive component 4, so as to adjust the distance between the two groups of skateboards 3, so as to facilitate clamping and fixing of engine casings of different sizes. The second drive component 7 drives the cross plate 6 to move up and down, so as to facilitate the suspension of the engine casing in the air, and then the third drive component 8 drives the rotating shaft 12 to rotate, so that the clamping component 9 rotates, so that the engine casing rotates 360 degrees, and the engine casing can be inspected 360 degrees in appearance, so as to improve the inspection efficiency and reduce the workload of the staff.

[0032] The first driving assembly 4 includes a first motor 401, which is fixedly mounted on the upper surface of the base 1, and the first motor 401 is located between the two groups of guide rails 2.

Both ends of the surface of the first forward and reverse screw rod 402 are threadedly connected with moving blocks 404, and the two groups of moving blocks 404 are respectively fixedly mounted on the lower surfaces of the two groups of skateboards 3. The first forward and reverse screw rod 402 is rotated by rotating the output shaft of the first motor 401 to drive the two groups of moving blocks 404 to move closer to or away from each other on the surface of the first forward and reverse screw rod 402, thereby changing the distance between the two groups of skateboards 3, and facilitating the adjustment of the appropriate distance according to the size of the engine casing, fixing the engine casing, and performing appearance inspection.

[0033] The second driving assembly 7 includes a threaded rod 701, one end of the threaded rod 701 is fixedly installed on the upper surface of the skateboard 3, and the other end is fixedly installed on the lower surface of the placement plate 10, and one end of the threaded rod 701 passes through the upper surface of the placement plate 10, and one end of the threaded rod 701 is fixedly installed with a second motor 702, and the second motor 702 is fixedly installed on the upper surface of the placement plate 10. A threaded hole is opened on the upper surface of the cross plate 6, and the cross plate 6 is threadedly connected to the threaded rod 701 through the threaded hole. The threaded rod 701 is rotated by rotating the output shaft of the second motor 702. Under the rotation of the threaded rod 701, the cross plate 6 moves upward or downward on the surface of the threaded rod 701, thereby adjusting the height of the engine casing, facilitating the rotation of the engine casing, and facilitating the cooperation of the staff to fix the engine casing.

[0034] A guide column 13 is fixedly installed between the skateboard 3 and the placement plate 10. A guide hole corresponding to the guide column 13 is opened on the upper surface of the cross plate 6. The guide column 13 is slidably connected in the guide hole. The guide column 13 limits the moving direction of the cross plate 6 while increasing the connectivity between the cross plate 6 and the threaded rod 701, thereby facilitating the height adjustment of the cross plate 6.

[0035] The third driving assembly 8 includes a worm wheel 801, which is fixedly mounted on the surface of the rotating shaft 12, and the worm wheel 801 is meshedly connected with a worm 802, and both ends of the worm 802 are rotatably connected with a second fixed plate 803, and one end of the worm 802 passes through one side of the second fixed plate 803, and the second fixed plate 803 is fixedly mounted on one side of the vertical plate 11. One end of the worm 802 is fixedly mounted with a first driving roller 804, and the surface of the first driving roller 804 is meshed with a toothed belt 805, and the toothed belt 805 is meshed with a first driving roller 804. A second driving roller 806 is provided, and a third motor 807 is fixedly installed at one end of the second driving roller 806.

The output shaft of the third motor 807 rotates, so that the second driving roller 806 drives the first driving roller 804 to rotate synchronously through the toothed belt 805, so as to drive the worm 802 to drive the worm wheel 801 to rotate, so that the rotating shaft 12 rotates synchronously with the worm wheel 801, so that the engine casing can be inspected for appearance at 360 degrees to improve the inspection efficiency.

[0036] The clamping assembly 9 includes a fixed seat 901, which is fixedly installed on one end of the rotating shaft 12, and a third fixed plate 902 is fixedly installed at both ends of one side of the fixed seat 901. A second positive and negative screw rod 903 is rotatably connected between the two groups of third fixed plates 902, and one end of the second positive and negative screw rod 903 passes through one end of the third fixed plate 902, and a fourth motor 904 is fixedly installed at one end of the second positive and negative screw rod 903. The fourth motor 904 is fixedly installed on one side of the third fixed plate 902, and both ends of the surface of the second positive and negative screw rod 903 are threadedly connected with a movable block 905, and a fourth fixed plate 906 is fixedly installed on one side of the movable block 905. Two groups of through holes are opened at one end of the fourth fixed plate 906, and a guide column 907 is slidably connected in the through hole.

A rubber plate 911 is fixedly installed at one end of the clamping plate 909. The output shaft of the fourth motor 904 rotates, so that the second positive and negative screw rods 903 drive the two groups of movable blocks 905 to move closer or farther away, so as to clamp the convenient part of the engine casing. During the clamping process, the rubber plate 911 contacts the engine casing, and the rubber plate 911 undergoes elastic deformation to protect the clamping part of the engine casing. At the same time, the guide column 907 slides in the through hole when the rubber plate 911 is subjected to force, and the clamping plate 909 applies pressure to the spring 910. The spring 910 deforms when subjected to force and provides a reverse force to the clamping plate 909, so that the two groups of rubber plates 911 clamp the engine casing more tightly to prevent the risk of the engine casing falling during the rotation process.
