Description

Technical Field

[0001] This utility model relates to the field of DR imaging technology, specifically a multi-turntable detection device for DR imaging. Background Technology

[0002] The DR imaging multi-turntable inspection device is a high-precision instrument used in industrial non-destructive testing, capable of omnidirectional inspection of workpieces with complex shapes. This device utilizes multiple turntables working in tandem to ensure multi-angle imaging of the workpiece under X-ray irradiation, thereby improving inspection accuracy and efficiency.

[0003] The technical solution disclosed in CN217586991U is a multi-turntable inspection device for DR imaging, used for omnidirectional scanning of workpieces. This application uses pulleys and synchronous belt drives to rotate multiple output shafts synchronously, achieving the goal of simultaneously scanning and inspecting multiple workpieces with DR, saving inspection time and improving inspection efficiency. However, the synchronous belt drive used in this application generates a large amount of heat during transmission. This heat is stored internally and cannot be dissipated in time. Prolonged exposure to an overheated working environment can cause internal cracking of the synchronous belt, affecting its service life and requiring frequent replacement.

[0004] To address this, we provide a multi-turntable detection device for DR imaging. Utility Model Content

[0005] The purpose of this invention is to provide a multi-turntable detection device for DR imaging to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-turntable detection device for DR imaging includes a transmission housing with multiple ventilation holes at the top and bottom, four support frames symmetrically arranged at the bottom of the transmission housing, through holes on both sides of the transmission housing, and heat dissipation components arranged on both sides of the inside of the transmission housing corresponding to the positions of the through holes.

[0008] Preferably, the heat dissipation component includes a cooling fan and a drive motor. The drive motor is symmetrically fixed to both sides of the inside of the transmission housing by bolts. The output end of the drive motor is fixed with a cooling fan, and a filter screen is provided inside the through hole.

[0009] Preferably, the transmission housing has an input shaft inside, and three rotating shafts are respectively arranged on both sides of the transmission housing. The six rotating shafts are arranged symmetrically with respect to the input shaft. The bottom of the rotating shaft is movably connected to the transmission housing, and the top of the rotating shaft extends out of the transmission housing and is provided with an indexing plate.

[0010] Preferably, pulleys are fitted in the middle of both the input shaft and the rotating shaft, and a synchronous belt is fitted on the outer side of each pulley, with the synchronous belt providing power connection to all pulleys.

[0011] Preferably, the bottom of the transmission housing is provided with multiple sliding grooves, and a lead screw is provided inside the sliding groove. The two ends of the lead screw are respectively movably connected to the transmission housing. A fixed slider is sleeved on the outside of the lead screw, and a tensioning wheel is provided at the top of the fixed slider. One side of the tensioning wheel abuts against the timing belt.

[0012] Preferably, an internally threaded disc is fitted on the outer side of one end of the lead screw that extends out of the transmission housing. A worm gear is fixed on one side of the internally threaded disc, and a worm is provided on the top of the worm gear. The worm gear meshes with the worm.

[0013] Preferably, one end of the worm gear is movably connected to the mounting block, the mounting block is fixed to the front end of the transmission housing, the worm gears are in pairs and the ends away from the mounting block are fixedly connected by a coupling, and a rotating handle is fixed to the outside of the coupling.

[0014] Preferably, a sleeve is fitted on the outer side of the bottom end of the input shaft, and a claw is fixed at the bottom of the sleeve.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] This invention uses a drive motor to rotate a cooling fan to dissipate the heat generated during the internal synchronous belt transmission, thus achieving a cooling effect and preventing the synchronous belt from overheating and causing internal cracks that could affect its service life. At the same time, the filter screen installed inside the through hole can prevent external dust from entering the transmission box and affecting the transmission effect.

[0017] This invention uses a rotating handle to drive a coupling to control the synchronous rotation of worm gears at both ends. The rotation of the worm gears drives the rotation of the worm wheel at the bottom, which in turn drives the rotation of the internal threaded disc. The rotation of the internal threaded disc drives the rotation of the lead screw, which in turn drives the fixed slider to move back and forth through a guide groove. The back and forth movement of the fixed slider drives the tensioning wheel to move back and forth to adjust the pressure on the timing belt, making it easy to adjust the belt tension simultaneously and quickly.

[0023] 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.

[0024] like Figure 1-4 As shown, a multi-turntable detection device for DR imaging includes a transmission housing 1. The top and bottom of the transmission housing 1 are provided with multiple ventilation holes 2. Four support frames 3 are symmetrically arranged at the bottom of the transmission housing 1. Through holes are provided on both sides of the transmission housing 1. Heat dissipation components are provided on both sides of the inside of the transmission housing 1 corresponding to the positions of the through holes.

[0025] like Figure 1 and Figure 2 As shown, the heat dissipation component includes a cooling fan 7 and a drive motor 8. The drive motor 8 is symmetrically fixed to both sides of the inside of the transmission housing 1 by bolts. The output end of the drive motor 8 is fixed with the cooling fan 7, and a filter screen 6 is provided inside the through hole.

[0026] An input shaft 9 is provided inside the transmission housing 1. Three rotating shafts 10 are provided on each of the two sides inside the transmission housing 1. The six rotating shafts 10 are arranged symmetrically with respect to the input shaft 9. The bottom of the rotating shafts 10 is movably connected to the transmission housing 1. The top of the rotating shafts 10 extends out of the transmission housing 1 and is provided with an indexing plate 12.

[0027] Both the input shaft 9 and the rotating shaft 10 are fitted with pulleys 11 in the middle, and a timing belt 13 is fitted on the outer side of the pulleys 11. The timing belt 13 is used to power all the pulleys 11.

[0028] In this embodiment, the input shaft 9 rotates to drive the pulley 11 to control the rotation of the synchronous belt 13. The rotation of the synchronous belt 13 drives the rotating shaft 10 to rotate through the pulley 11. The rotation of the rotating shaft 10 drives the indexing plate 12 to rotate. The heat generated when the synchronous belt 13 rotates can be dissipated to the outside through the vent 2. The drive motor 8 is turned on, and the drive motor 8 drives the cooling fan 7 to rotate to dissipate the heat generated when the internal synchronous belt 13 is driven, thereby achieving a cooling effect and preventing the synchronous belt 13 from overheating and causing internal cracking, which would affect its service life. At the same time, the filter screen 6 set inside the through hole can prevent external dust from entering the transmission box 1 through the through hole and affecting the transmission effect.

[0029] like Figure 3 and Figure 4 As shown, multiple sliding grooves 14 are provided at the bottom of the transmission housing 1. A lead screw 15 is provided inside the sliding groove 14. Both ends of the lead screw 15 are movably connected to the transmission housing 1. A fixed slider 16 is sleeved on the outside of the lead screw 15. A tension wheel 17 is provided at the top of the fixed slider 16. One side of the tension wheel 17 abuts against the synchronous belt 13.

[0030] The lead screw 15 extends out of the transmission housing 1 and is fitted with an internal threaded disc 21 on the outer side. A worm wheel 20 is fixed on one side of the internal threaded disc 21, and a worm 19 is provided on the top of the worm wheel 20. The worm wheel 20 meshes with the worm 19.

[0031] One end of the worm gear 19 is movably connected to the mounting block 18, which is fixed to the front end of the transmission housing 1. The worm gears 19 are in pairs, and the ends away from the mounting block 18 are fixedly connected by a coupling 22. A handle 23 is fixed on the outside of the coupling 22.

[0032] A sleeve 4 is fitted on the outer side of the bottom end of the input shaft 9, and a claw 5 is fixed at the bottom of the sleeve 4.

[0033] In this embodiment, the adjusted utility model is installed at a designated position above the turntable of the testing equipment. It is fixed to the external fixed equipment by the support frame 3 set on the bottom surface of the transmission box 1. The claw 5 is inserted into the T-slot of the CNC turntable through the sleeve 4 and rotates together with the CNC turntable, so that the input shaft 9 obtains input power. When it is necessary to adjust the tension of the synchronous belt 13 to control the speed of the indexing plate 12, the handle 23 can be rotated. The handle 23 drives the coupling 22 to control the synchronous rotation of the worm gears 19 at both ends. The rotation of the worm gears 19 drives the worm wheel 20 at the bottom to rotate. The rotation of the worm wheel 20 drives the internal threaded disc 21 to rotate. The rotation of the internal threaded disc 21 drives the lead screw 15 to rotate. The rotation of the lead screw 15 drives the fixed slider 16 to move back and forth through the guide of the slide groove 14. The back and forth movement of the fixed slider 16 drives the tensioning wheel 17 to move back and forth to adjust the pressure on the synchronous belt 13, so as to control the speed of the indexing plate 12.

[0034] The working principle of this utility model is as follows: A support frame 3, located on the bottom surface of the transmission housing 1, is fixed to an external device. A claw 5 is inserted into the T-slot of the CNC rotary table via a sleeve 4 and rotates with the rotary table, thus providing input power to the input shaft 9. The rotation of the input shaft 9 drives the pulley 11 to control the rotation of the synchronous belt 13. The rotation of the synchronous belt 13, through the pulley 11, drives the rotating shaft 10 to rotate, which in turn drives the indexing plate 12. The heat generated by the synchronous belt 13 during rotation can be dissipated through the vent 2. By turning on the drive motor 8, the cooling fan 7 is activated to dissipate the heat generated by the synchronous belt 13 during transmission, achieving a cooling effect and preventing overheating that could cause internal cracking and affect its service life. Simultaneously, a filter screen 6 installed inside the vent prevents external dust from entering the transmission housing 1 and affecting the transmission effect. When it is necessary to adjust the tension of the timing belt 13 to control the speed of the indexing plate 12, the handle 23 can be rotated. The handle 23 drives the coupling 22 to control the worm gears 19 at both ends to rotate synchronously. The rotation of the worm gears 19 drives the worm wheel 20 at the bottom to rotate. The rotation of the worm wheel 20 drives the internal threaded disc 21 to rotate. The rotation of the internal threaded disc 21 drives the lead screw 15 to rotate. The rotation of the lead screw 15 drives the fixed slider 16 to move back and forth through the guide groove 14. The back and forth movement of the fixed slider 16 drives the tensioning wheel 17 to move back and forth to adjust the pressure on the timing belt 13, which facilitates the control of the speed of the indexing plate 12.
