Description

Technical Field

[0001] This utility model relates to the field of mounting rack technology, and in particular to a mounting rack for spindle machining. Background Technology

[0002] In mechanical engineering, a spindle refers to the shaft that receives power from an engine or electric motor and transmits it to other machine parts. It is one of the core components of machining equipment, responsible for driving the rotation of cutting tools or workpieces to achieve cutting operations. Its performance directly affects machining accuracy, efficiency, and product quality.

[0003] A mounting bracket is used during bearing machining. Existing mounting brackets are not adjustable; after removing the upper shaft, workers need to bend over to remove the lower shaft. Furthermore, the shafts are typically placed on a workbench, lacking sufficient restraint. Therefore, we designed a mounting bracket for spindle machining. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mounting bracket for spindle machining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spindle machining support includes two base plates, a side plate fixed to the top of the base plates, a conveying mechanism installed between the two side plates, and a plurality of clamping mechanisms installed at equal intervals on the conveying mechanism.

[0007] The clamping mechanism includes two symmetrically arranged U-shaped frames. The top of each U-shaped frame has a slot, and a pressure plate is connected to the slot via a torsion spring. A connecting rod is fixed between the two pressure plates. The U-shaped frames have holes for the connecting rod to pass through. A stop bar is fixed to the top of the outer wall of each of the two side plates. A lever corresponding to the stop bar is fixed to the outer wall of the connecting rod. The pressure plate connected by the torsion spring presses against the spindle to maintain a certain stability. When the clamping mechanism moves the spindle to its highest position, the lever contacts the stop bar, forcing the connecting rod to drive the pressure plate to deflect counterclockwise, making it easier to manually remove the spindle and making it more convenient to remove.

[0008] As a further embodiment of this utility model, the bottom of the base plate is fixed with casters.

[0009] As a further embodiment of this utility model, the conveying mechanism includes a first conveying roller and a second conveying roller, which are connected by a conveyor belt. A drive motor for driving the second conveying roller to rotate is fixed to the outer wall of one of the side plates. A control panel is fixed to the outer wall of the side plate and is electrically connected to the drive motor.

[0010] As a further embodiment of this utility model, a second sprocket is coaxially fixed at both ends of the first conveyor roller, and a first sprocket is coaxially fixed at both ends of the second conveyor roller. The first sprocket and the second sprocket are connected by a chain. The first sprocket and the second sprocket are rotatably connected to the corresponding side plates. The output shaft of the drive motor is coaxially fixed to the first sprocket through a coupling. Both sides of the conveyor belt are fixed to the two chains.

[0011] As a further embodiment of this utility model, a support plate is fixed to the bottom of the inner wall of the U-shaped frame, and an arc-shaped groove is provided on the support plate for placing the main shaft and preventing it from rolling out.

[0012] As a further embodiment of this utility model, the two U-shaped frames on the clamping mechanism are fixed with the same mounting plate, the mounting plate is fixed to the outer wall of the conveyor belt, and the conveyor belt is a sheet metal conveyor belt.

[0013] The beneficial effects of this utility model are:

[0014] This utility model is equipped with a base plate, side plates, a conveying mechanism, a clamping mechanism, and a stop bar. The drive motor drives the rotation of the second conveying roller, which, in conjunction with the first conveying roller, enables the conveyor belt to be transported. The start and stop are controlled via a control panel. After the main shaft at the highest point is removed, the drive motor can be controlled to run the conveying mechanism until the main shaft of the next layer moves to the highest position. This process is repeated so that each time the main shaft is removed, it is always at the highest position for easy removal.

[0015] This invention is useful in that when placing the spindle, the lever needs to be turned so that the pressure plate deflects counterclockwise to facilitate the placement of the spindle. The pressure plate connected by the torsion spring squeezes the spindle to maintain a certain stability. When the clamping mechanism moves the spindle to the highest position, the lever contacts the stop bar, forcing the connecting rod to drive the pressure plate to deflect counterclockwise, making it easier to manually remove the spindle and making it more convenient to take out.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-4 A spindle machining placement frame includes two base plates 1, a side plate 2 fixed to the top of the base plate 1, a conveying mechanism 3 installed between the two side plates 2, and a plurality of clamping mechanisms 12 installed at equal intervals on the conveying mechanism 3.

[0024] The clamping mechanism 12 includes two symmetrically arranged U-shaped frames 15. The top of the U-shaped frame 15 has a slot 16, and a pressure plate 17 is connected to the slot 16 through a torsion spring. The same connecting rod 19 is fixed between the two pressure plates 17. The U-shaped frame 15 has a hole for the connecting rod 19 to pass through. The top of the outer wall of the two side plates 2 is fixed with the same stop rod 13. The outer wall of the connecting rod 19 is fixed with a lever 20 corresponding to the stop rod 13. The pressure plate 17 connected by the torsion spring squeezes the spindle to maintain a certain stability. When the clamping mechanism 12 drives the spindle to move to the highest position, the lever 20 contacts the stop rod 13, forcing the connecting rod 19 to drive the pressure plate 17 to deflect counterclockwise, which makes it easier to manually remove the spindle and makes it more convenient to remove.

[0025] In this embodiment, a caster wheel 11 is fixed to the bottom of the base plate 1.

[0026] In this embodiment, the conveying mechanism 3 includes a first conveying roller 5 and a second conveying roller 6. The first conveying roller 5 and the second conveying roller 6 are connected by a conveyor belt 4. A drive motor 10 for driving the second conveying roller 6 to rotate is fixed on the outer wall of one of the side plates 2. A control panel is fixed on the outer wall of the side plate 2, and the control panel is electrically connected to the drive motor 10.

[0027] In this embodiment, the two ends of the first conveying roller 5 are coaxially fixed with second sprockets 9, and the two ends of the second conveying roller 6 are coaxially fixed with first sprockets 7. The first sprockets 7 and second sprockets 9 are connected by chains 8. The first sprockets 7 and second sprockets 9 are rotatably connected to the corresponding side plates 2. The output shaft of the drive motor 10 is coaxially fixed with the first sprocket 7 through a coupling. The two sides of the conveyor belt 4 are fixed with two chains 8. The drive motor 10 directly drives the first sprockets 7 and the second conveying roller 6 to rotate. Under the action of the first sprockets 7, the second sprockets 9 and the chains 8, the conveyor belt 4 is moved, effectively avoiding slippage.

[0028] In this embodiment, a support plate 18 is fixed to the bottom of the inner wall of the U-shaped frame 15, and an arc-shaped groove is provided on the support plate 18 for placing the main shaft and preventing it from rolling out.

[0029] In this embodiment, the two U-shaped frames 15 on the clamping mechanism 12 are fixed with the same mounting plate 14. The mounting plate 14 is fixed to the outer wall of the conveyor belt 4, which is a sheet metal conveyor belt.

[0030] Working principle: The system includes a base plate 1, side plates 2, a conveying mechanism 3, a clamping mechanism 12, and a stop bar 13. During use, the main shaft can be placed on the support plate 18 within the U-shaped frame 15. It should be noted that longer main shafts can be placed on the same clamping mechanism 12, i.e., within two U-shaped frames 15, while shorter main shafts can be placed within one U-shaped frame 15. Multiple main shafts can be placed on one side of the conveyor belt 4. The second conveying roller 6 is rotated by the drive motor 10, which, combined with the first conveying roller 5, enables the conveying of the conveyor belt 4. Start and stop are controlled via the control panel. After the main shaft is removed, the drive motor 10 can be controlled to make the conveying mechanism 3 run until the main shaft of the next layer moves to the highest position. This process is repeated so that the main shaft is always in the highest position when it is removed, making it easy to take out. When placing the main shaft, the lever 20 needs to be turned so that the pressure plate 17 deflects counterclockwise, which facilitates the placement of the main shaft. The pressure plate 17 connected by the torsion spring squeezes the main shaft to maintain a certain stability. When the clamping mechanism 12 drives the main shaft to move to the highest position, the lever 20 contacts the stop bar 13, which forces the connecting rod 19 to drive the pressure plate 17 to deflect counterclockwise, making it easier to manually remove the main shaft and making it more convenient to take out.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
