[0015] A method for using a positioning device for cable tray assembly includes the following steps:

[0016] Step 1: The top of the base is equipped with a support groove. Place the cable tray in the support groove, and then the cylinder drives the lifting column to move down, simultaneously moving the lifting plate and the connecting seat down. The lifting plate is not in contact with the motor. The connecting seat applies a pulling force to spring one. Spring one pulls the horizontal plate down. The connecting seat applies a pushing force to the two push plates. With the use of spring two, spring two applies a pushing force to the connecting plate, which can push the side pressure plate to move. Furthermore, the connecting seat drives the pressure plate and the fixed cylinder to move down.

[0017] Step 2: After the connecting seat moves down to the appropriate position, spring 1 is pulled tight to the lifting plate, the lifting plate presses against the top of the two side plates, and the two side pressure plates press against the inner side of the two side plates. Spring 2 is in a compressed state, the pressure plate presses against the bottom plate, and spring 3 is in a compressed state, thereby achieving the purpose of centering the cable tray and also achieving full locking and fixing, improving stability, and providing a good foundation for subsequent processing. At this time, the lifting plate is connected to the top of the motor.

[0018] Step 3: The cylinder continues to drive the lifting column to move downwards, which in turn drives the connecting seat to move downwards. The lifting plate presses further against the top of the two side plates, and the two side pressure plates also press further against the inner side of the two side plates. The pressure plate presses further against the bottom plate, which improves the stability of the cable tray. The downward movement of the lifting column causes the lifting plate to continue to move downwards. The lifting plate presses against the motor, which drives the motor and sliding plate to move downwards, allowing the four drill rods to pass through the corresponding positioning holes to drill holes in the top of the side plates, improving drilling accuracy and efficiency. At this time, the four springs are in a compressed state.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is equipped with a positioning mechanism and a drilling mechanism. The positioning mechanism includes a cylinder, a lifting column, a horizontal plate, a first spring, a connecting seat, two push plates, two connecting plates, two second springs, two side pressure plates, an elastic support mechanism, a guide interface, and a spring groove. The elastic support mechanism includes a pressure plate, a fixed cylinder, a pressing column, an inner cavity, a third spring, and a sliding block. The drilling mechanism includes a sliding plate, a motor, two drill rods, a fourth spring, two driven teeth, a transmission chain, and a drive tooth. The cylinder drives the lifting column to move downward, synchronously driving the lifting plate and the connecting seat to move downward. The lifting plate is not in contact with the motor. The connecting seat applies a pulling force to the first spring, which pulls the horizontal plate downward. The connecting seat applies a pushing force to the two push plates. With the use of the second spring, the second spring applies a pushing force to the connecting plate, which can push the side pressure plate. As the plate moves, the connecting seat drives the pressure plate and the fixed cylinder to move downwards. When the connecting seat moves to a suitable position, the horizontal plate presses against the top of the two side plates, and the two side pressure plates press against the inner side of the two side plates. Spring 2 is in a compressed state, the pressure plate presses against the bottom plate, and spring 3 is in a compressed state, thereby achieving the purpose of aligning the cable tray and placing the positioning holes in a suitable position, which facilitates subsequent drilling of the top of the side plates. It is applicable to cable trays of different widths and also achieves comprehensive locking and fixing, improving stability and providing a good foundation for subsequent processing. At this time, the lifting plate just contacts the top of the motor, and the cylinder continues to drive the lifting column to move downwards, so that the lifting plate presses against the two motors, which can drive the sliding plate and the drill rod to move downwards, so that the drill rod passes through the corresponding positioning holes to drill holes in the top of the side plates, improving drilling accuracy and efficiency, and making it highly practical.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 8 This invention provides a positioning device for assembling cable trays, including a base 1 and a fixing frame 2 connected to the top of the base 1. The fixing frame 2 is connected to a positioning mechanism for positioning the cable tray. The positioning mechanism includes a cylinder 3, a lifting column 16, a horizontal plate 5, a spring 20, a connecting seat 21, two push plates 13, two connecting plates 12, two springs 24, two side pressure plates 9, and an elastic support mechanism. The cylinder 3 is used to drive the lifting column 16 to rise and fall. The lifting column 16 passes through the horizontal plate 5. The length of the horizontal plate 5 is greater than the width of the cable tray. The two ends of the spring 20 are connected to the connecting seat 21 and the lifting plate 4. The elastic support mechanism is used to support the connecting seat 21. The end of the push plate 13 is hinged to the connecting seat 21. One end of the connecting plate 12 is inserted into the push plate 13, and the other end is hinged to the side pressure plate 9. When the included angle between the two push plates 13 gradually increases, the spring 24 is gradually compressed, which increases the pressure of the connecting plate 12 on the side pressure plate 9. That is, the side pressure plate 9 gradually presses against the side plate 111, improving the stability of the cable tray. The side pressure plate 9 can move along the length of the horizontal plate 5. Spring 24 is used to drive the connecting plate 12 to move away from the push plate 13. The side pressure plate 9 is connected to a drilling mechanism, which includes a sliding plate 8, a motor 7, two drill rods 10, and spring 30. The sliding plate 8 is vertically connected to the side pressure plate 9. The motor 7 is used to drive the two drill rods 10 to rotate synchronously. Spring 30 is used to drive the sliding plate 8 to move away from the horizontal plate 5. The lifting column 16 is connected to a lifting plate 4 for pressing the drill rods 10 to move downward.

[0031] The cable tray is placed in the support groove 6, and the cable tray can be tilted. The cylinder 3 drives the lifting column 16 to move down, and simultaneously drives the lifting plate 4 and the connecting seat 21 to move down. At this time, the lifting plate 4 is not in contact with the motor 7. The connecting seat 21 applies a pulling force to the spring 20, and the spring 20 pulls the horizontal plate 5 down. The connecting seat 21 applies a pushing force to the two push plates 13. With the use of the second spring 24, the second spring 24 applies a pushing force to the connecting plate 12, which can push the side pressure plate 9 to move. The direction of movement is away from the lifting column 16. Furthermore, the connecting seat 21 drives the pressure plate 14 and the fixed cylinder 15 to move down. After the connecting seat 21 moves down to a suitable position, the horizontal plate 5 presses down on the top of the two side plates 111, while the two side pressure plates 9 press tightly against the inner side of the two side plates 111. The second spring 24 is in a compressed state, the pressure plate 14 presses tightly against the bottom plate 112, and the third spring 27 is in a compressed state, thereby achieving the purpose of aligning the cable tray and placing the positioning hole 11 in a suitable position, which facilitates subsequent drilling of the top of the side plate 111. It can be applied to cable trays of different widths, and also achieves full locking and fixation, improving stability and providing a good foundation for subsequent processing. At this time, the lifting plate 4 just contacts the top of the motor 7 (state one). Cylinder 3 continues to drive the lifting column 16 to move downward, causing the lifting plate 4 to press against the two motors 7, which can drive the sliding plate 8 and the drill rod 10 to move downward. At this time, the spring 30 is in a gradually compressed state, causing the drill rod 10 to pass through the corresponding positioning hole 11 to drill a hole in the top of the side plate 111, improving drilling accuracy and efficiency, and making it highly practical (state two). As the lifting column 16 continues to move downward, the connecting seat 21 also continues to move downward, and the spring 20 is further stretched, which increases the pressure exerted by the horizontal plate 5 on the side plate 111. The included angle between the two push plates 13 is further increased, which further compresses the spring 24, that is, the side pressure plate 9 is further pressed against the inside of the side plate 111. The fixed cylinder 15 moves downward further, and the spring 27 is further compressed, which increases the pressure exerted by the pressure plate 14 on the bottom plate 112, further improving the stability of the cable tray.

[0032] After the cable tray is processed, cylinder 3 drives the lifting column 16 to move upward, simultaneously driving the lifting plate 4 and connecting seat 21 to move upward. The compressed spring 4 30 returns to its original position, lifting the sliding plate 8, simultaneously driving the motor 7 and drill rod 10 to move upward, separating the drill rod 10 from the drill hole. Meanwhile, the pressure plate 14 remains pressed against the base plate 112, and the side pressure plate 9 remains pressed against the side plate 111. The cable tray is still in a fixed state (changing from state two to state one). Cylinder 3 continues to drive the lifting column 16 to move upward, and the lifting plate 4 and connecting seat 21 move upward. When the machine 7 is separated, the connecting seat 21 moves further upward, applying a pushing force to the spring 20, which can push the horizontal plate 5 upward and separate it from the top of the side plate 111. At the same time, the included angle between the two push plates 13 decreases, and the spring 24 pulls the connecting plate 12 back, so that the two side pressure plates 9 move closer to each other and separate from the side plate 111. Furthermore, the connecting seat 21 pulls the fixing cylinder 15 and the pressure plate 14 upward, so that the pressure plate 14 separates from the bottom plate 112, realizing the complete loosening of the cable tray and making it easy to remove from the support groove 6.

[0033] The positioning mechanism also includes a guide interface 19 and a spring groove 25. The guide interface 19 is connected to the bottom of the lifting plate 4, the lifting column 16 passes through the guide interface 19, the spring groove 25 is set in the push plate 13, the second spring 24 is located in the spring groove 25, and the two ends of the second spring 24 are connected to the connecting plate 12 and the push plate 13. The connecting plate 12 is slidably connected to the spring groove 25, so that the connecting plate 12 moves stably.

[0034] Spring 20 is fitted onto lifting column 16, and both ends of spring 20 are connected to guide interface 19 and connecting seat 21.

[0035] The elastic support mechanism includes a pressure plate 14, a fixed cylinder 15, a pressing column 22, an inner cavity 26, a spring 27, and a sliding block 28. The fixed cylinder 15 is connected to the bottom of the connecting seat 21. The sliding block 28 guides the pressing column 22. The pressure plate 14 is connected to the end of the pressing column 22. The inner cavity 26 is located inside the fixed cylinder 15. The two ends of the spring 27 are connected to the sliding block 28 and the fixed cylinder 15. When the cable tray is in the positioning state, the pressure plate 14 is pressed against the middle of the base plate 112, and the sliding block 28 provides good guidance for the pressure plate 14, making the lifting and lowering of the pressure plate 14 stable. As the fixed cylinder 15 gradually moves downward, the pressing column 22 gradually inserts into the inner cavity 26, the sliding block 28 moves upward relative to the fixed cylinder 15, and the spring 27 is gradually compressed, causing the pressure exerted by the pressure plate 14 on the base plate 112 to gradually increase, thus providing good fixation for the base plate 112.

[0036] The sliding block 28 is slidably connected to the inner cavity 26, and the sliding block 28 is fixedly connected to the end of the pressing column 22.

[0037] The horizontal plate 5 has two rectangular holes 23. The side pressure plate 9 is slidably connected to the corresponding rectangular holes 23, so that the side pressure plate 9 moves stably. The horizontal plate 5 is provided with multiple positioning holes 11 that match the drill rod 10. There can be four positioning holes 11. The drill rod 10 passes through the corresponding positioning holes 11 to process the top of the side plate 111, which can improve the drilling accuracy and prevent it from being skewed.

[0038] The drilling mechanism also includes two driven teeth 34, a transmission chain 33, and a drive tooth 32. A motor 7 is connected to the top of the sliding plate 8, and the power output end of the motor 7 is connected to the drive tooth 32. The drive tooth 32 and the driven teeth 34 are rotatably connected to the bottom of the sliding plate 8. The drive tooth 32 and the two driven teeth 34 are connected via the transmission chain 33. The end of the drill rod 10 is connected to the driven teeth 34. The motor 7 can drive the drive tooth 32 to rotate, and through the transmission chain 33, it can drive the two driven teeth 34 to rotate. The driven teeth 34 drive the corresponding drill rod 10 to rotate, facilitating drilling of the top of the side plate 111. The drilling depth is controllable; simply moving the lifting column 16 further downwards will move the lifting plate 4 downwards, causing the motor 7 and drill rod 10 to move further downwards.

[0039] The transmission connection is a chain drive, which has a simpler structure and higher transmission efficiency compared to other transmission methods, making it suitable for long-term, high-power transmission. It has a high load-bearing capacity, is less prone to breakage, and is relatively stable and reliable, suitable for long-term operation.

[0040] The side of the side pressure plate 9 is provided with a groove 29, and the sliding plate 8 is slidably connected to the groove 29. A guide post 31 is connected inside the groove 29, and the sliding plate 8 is slidably connected to the guide post 31. The four springs 30 are sleeved on the guide post 31, and both ends of the four springs 30 are connected to the sliding plate 8 and the side pressure plate 9. The groove 29 and the guide post 31 can make the sliding plate 8 rise and fall stably. During the downward movement of the sliding plate 8, the lifting plate 4 continuously presses against the motor 7, and the four springs 30 are gradually compressed. The guide post 31 can prevent the four springs 30 from undergoing large deformation and play a protective role for the four springs 30.

[0041] The lifting column 16 is connected to the annular seat 18, the lifting plate 4 is fixedly connected to the annular seat 18, and the end of the lifting plate 4 is slidably connected to the vertical groove 17 set inside the fixed frame 2, which can improve the stability of the lifting plate 4, that is, the lifting column 16 moves steadily.

[0042] During the cable tray positioning process, the distance between the two side pressure plates 9 is controlled by the lifting column 16, while the position of the horizontal plate 5 remains unchanged. This method is suitable for fixing wider cable trays (meaning that the distance between the two side plates 111 is relatively large), making it highly adaptable.

[0043] A method for using a positioning device for cable tray assembly includes the following steps:

[0044] Step 1: The top of the base 1 is provided with a support groove 6. The bridge frame is placed in the support groove 6, and then the cylinder 3 drives the lifting column 16 to move down, which simultaneously drives the lifting plate 4 and the connecting seat 21 to move down. The lifting plate 4 is not in contact with the motor 7. The connecting seat 21 applies a pulling force to the spring 20. The spring 20 pulls the horizontal plate 5 down. The connecting seat 21 applies a pushing force to the two push plates 13. With the use of the second spring 24, the second spring 24 applies a pushing force to the connecting plate 12, which can push the side pressure plate 9 to move. Furthermore, the connecting seat 21 drives the pressure plate 14 and the fixed cylinder 15 to move down.

[0045] Step 2: After the connecting seat 21 moves down to a suitable position, spring 1 20 is pulled tight to the lifting plate 4, the horizontal plate 5 is pressed against the top of the two side plates 111, and the two side pressure plates 9 are pressed against the inner side of the two side plates 111. Spring 2 24 is in a compressed state, the pressure plate 14 is pressed against the bottom plate 112, and spring 3 27 is in a compressed state, thereby achieving the purpose of centering the cable tray, and also achieving full locking and fixing, improving stability, and providing a good foundation for subsequent processing. At this time, the lifting plate 4 is connected to the top of the motor 7.

[0046] Step 3: Cylinder 3 continues to drive the lifting column 16 to move down, which in turn drives the connecting seat 21 to move down. The lifting plate 4 presses further against the top of the two side plates 111, and the two side pressure plates 9 also press further against the inner side of the two side plates 111. The pressure plate 14 presses further against the bottom plate 112, which improves the stability of the cable tray. The downward movement of the lifting column 16 causes the lifting plate 4 to continue to move down. The lifting plate 4 presses against the motor 7, which drives the motor 7 and the sliding plate 8 to move down, so that the four drill rods 10 pass through the corresponding positioning holes 11 to drill holes in the top of the side plates 111, improving the drilling accuracy and efficiency. At this time, the spring 30 is in a compressed state.

9. A positioning device for cable tray assembly according to claim 1, characterized in that, The lifting column (16) is connected to an annular seat (18), the lifting plate (4) is fixedly connected to the annular seat (18), and the end of the lifting plate (4) is slidably connected to the vertical groove (17) provided inside the fixed frame (2).

10. A method of using a positioning device for cable tray assembly according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: The top of the base (1) is provided with a support groove (6). The bridge frame is placed in the support groove (6). Then the cylinder (3) drives the lifting column (16) to move down, and simultaneously drives the lifting plate (4) and the connecting seat (21) to move down. The lifting plate (4) is not in contact with the motor (7). The connecting seat (21) applies a pulling force to the first spring (20). The first spring (20) pulls the horizontal plate (5) down. The connecting seat (21) applies a pushing force to the two push plates (13). With the use of the second spring (24), the second spring (24) applies a pushing force to the connecting plate (12), which can push the side pressure plate (9) to move. Furthermore, the connecting seat (21) drives the pressure plate (14) and the fixed cylinder (15) to move down. Step 2: When the connecting seat (21) moves down to a suitable position, spring 1 (20) is pulled tight to the horizontal plate (5), the horizontal plate (5) is pressed against the top of the two side plates (111), and the two side pressure plates (9) are pressed against the inner side of the two side plates (111). Spring 2 (24) is in a compressed state, the pressure plate (14) is pressed against the bottom plate (112), and spring 3 (27) is in a compressed state, thereby achieving the purpose of centering the bridge frame, and also achieving full locking and fixing, improving stability, and providing a good foundation for subsequent processing. At this time, the lifting plate (4) is connected to the top of the motor (7). Step 3: The cylinder (3) continues to drive the lifting column (16) to move down, and continues to drive the connecting seat (21) to move down. The horizontal plate (5) presses further on the top of the two side plates (111), and the two side pressure plates (9) also press further on the inner side of the two side plates (111). The pressure plate (14) presses further on the bottom plate (112), which improves the stability of the bridge frame. The downward movement of the lifting column (16) causes the lifting plate (4) to continue to move down. The lifting plate (4) presses on the motor (7), which drives the motor (7) and the sliding plate (8) to move down, so that the four drill rods (10) pass through the corresponding positioning holes (11) to drill holes in the top of the side plate (111), which improves the drilling accuracy and efficiency. At this time, the spring four (30) is in a compressed state.
