Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a centering clamping device for shaft workpieces. Background Technology

[0002] Shafts are a common type of part in mechanical manufacturing. They are generally cylindrical mechanical parts whose length is greater than their diameter and are mainly used to support rotating parts (such as gears, pulleys, sprockets, etc.) and transmit motion and power.

[0003] When machining shaft-type workpieces, existing clamping mechanisms can only fix them. When different surfaces need to be machined, the workpiece must be clamped and fixed, flipped over, and then fixed again. This method is inefficient, affects the machining progress, and is inconvenient to operate. Therefore, this application proposes a centering clamping device for shaft-type workpieces. Utility Model Content

[0004] The purpose of this invention is to address the problem of inconvenience in processing different surfaces in the prior art by proposing a centering and clamping device for shaft-type workpieces.

[0005] The technical solution of this utility model: a centering and clamping device for shaft-type workpieces, including a base plate, and further comprising:

[0006] Mounting plate, the mounting plate is fixedly mounted on base plate, mounting columns are symmetrically fixedly mounted on base plate, sleeves are rotatably mounted on mounting columns, and a limiting mechanism is provided on base plate to fix and rotate shaft-like workpieces inside sleeves;

[0007] A guiding mechanism, which is mounted on the base plate, is used to move shaft-type workpieces inside the sleeve.

[0008] Optionally, the limiting mechanism includes a first gear fixedly sleeved on the sleeve, a second gear rotatably mounted on one side of the mounting column, the second gear meshing with the first gear, a mounting ring fixedly mounted on the sleeve, a plurality of circumferentially arranged electric telescopic rods fixedly mounted on one side of the mounting ring, a connecting ring slidably mounted on the sleeve, one end of the electric telescopic rod being fixedly connected to the connecting ring, a guide rod hinged to the connecting ring, a connecting rod symmetrically slidably mounted on the sleeve, one side of the connecting rod being hinged to the guide rod, and a clamping plate slidably mounted on one end of the connecting rod penetrating the sleeve, the clamping plate being arc-shaped.

[0009] Optionally, the guiding mechanism includes a slide plate slidably mounted on a mounting plate, the bottom of the slide plate being cut-faced, a rotating roller rotatably mounted on the slide plate, an anti-slip pad being provided on the rotating roller, a guide block slidably mounted on one side of the bottom of the mounting plate, the guide block being cut-faced and in contact with the slide plate, and guide wheels being fixedly mounted at equal intervals on the clamping plate.

[0010] Optionally, a first motor is fixedly installed on one side of the mounting column, the output shaft of the first motor is fixedly connected to a second gear, and a mounting bracket is fixedly installed on one side of the mounting plate, the mounting bracket being rotatably connected to the second gear.

[0011] Optionally, a second motor is fixedly installed on one side of the slide plate, the output shaft of the second motor is fixedly connected to the rotating roller, a connecting rod is slidably installed on the bottom side of the mounting plate, one end of the connecting rod is fixedly connected to the guide block, and a first spring is sleeved on the connecting rod.

[0012] Optionally, a pull plate is slidably mounted on one side of the bottom of the mounting plate, and one side of the pull plate is fixedly connected to the guide block.

[0013] Optionally, a second spring is fixedly installed at one end of the connecting rod, and one end of the second spring is fixedly connected to the clamping plate.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This invention uses an electric telescopic rod to move a connecting ring, causing a guide rod at one end of the connecting ring to press against a connecting rod. A clamp at one end of the connecting rod fixes the shaft-like workpiece. In conjunction with a first motor driving a second gear to rotate, the fixed shaft-like workpiece can rotate, improving processing efficiency and facilitating adjustment.

[0016] Furthermore, the supporting force provided by the first spring causes the guide block to press against the bottom of the slide plate, while the rotating roller at the top of the slide plate presses against the bottom of the shaft-like workpiece. In conjunction with the second motor driving the rotating roller to rotate, the shaft-like workpiece is horizontally displaced, thus improving processing efficiency.

[0017] This invention enables the shaft-type workpiece to rotate while also moving horizontally, improving processing efficiency and facilitating operation. Attached Figure Description

[0029] Example

[0030] like Figure 1 , Figure 2 As shown, the centering and clamping device for shaft workpieces proposed in this utility model includes a base plate 1 and a mounting plate 2. The mounting plate 2 is fixedly mounted on the base plate 1. Mounting columns 3 are symmetrically fixedly mounted on the base plate 1. A sleeve 4 is rotatably mounted on the mounting columns 3 for placing shaft workpieces. A limiting mechanism is provided on the base plate 1 to fix and rotate the shaft workpieces in the sleeve 4.

[0031] like Figure 2 , Figure 3As shown, the limiting mechanism includes a first gear 15 fixedly sleeved on the sleeve 4, a second gear 14 rotatably mounted on one side of the mounting post 3, the second gear 14 meshing with the first gear 15, a mounting ring 5 fixedly mounted on the sleeve 4, a plurality of circumferentially arranged electric telescopic rods 6 fixedly mounted on one side of the mounting ring 5, a connecting ring 7 slidably mounted on the sleeve 4, one end of the electric telescopic rod 6 being fixedly connected to the connecting ring 7, a guide rod 8 hinged to the connecting ring 7, and a connecting rod 9 symmetrically slidably mounted on the sleeve 4, one side of the connecting rod 9 being hinged to the guide rod 8, and the connecting rod 9 sliding through one end of the sleeve 4. A clamping plate 21 is installed, which is arc-shaped to center the shaft-like workpiece when clamping it. The electric telescopic rod 6 is activated, and its retraction causes the connecting ring 7 to move. Since one end of the guide rod 8 is hinged to the connecting rod 9, the connecting rod 9 moves downward when the connecting ring 7 retracts, thus fixing the shaft-like workpiece placed in the sleeve 4. The second gear 14 is rotated, which drives the first gear 15 to rotate, thereby causing the shaft-like workpiece fixed in the sleeve 4 to rotate. When it is necessary to remove the fixation of the shaft-like workpiece, the electric telescopic rod 6 can be extended.

[0032] like Figures 2-4 As shown, the guiding mechanism includes a slide plate 10 slidably mounted on a mounting plate 2. The bottom of the slide plate 10 is cut-out. A rotating roller 11 is rotatably mounted on the slide plate 10. The rotating roller 11 is provided with an anti-slip pad to improve friction. A guide block 19 is slidably mounted on one side of the bottom of the mounting plate 2. The guide block 19 is cut-out and contacts the slide plate 10. Guide wheels 16 are fixedly mounted at equal intervals on the clamping plate 21. A connecting rod 20 is slidably mounted on one side of the bottom of the mounting plate 2. One end of the connecting rod 20 is fixedly connected to the guide block 19. A first spring 18 is sleeved on the connecting rod 20. The first spring 18 provides a supporting force to the guide block 19, causing the guide block 19 on one side of the connecting rod 20 to squeeze the slide plate 10, causing it to move upward. This ensures that the top of the rotating roller 11 is always in contact with and presses against the bottom of the shaft-like workpiece. The guide wheels 16 can only move in the lateral directions. In conjunction with the rotation of the rotating roller 11, the shaft-like workpiece can rotate and move horizontally at the same time, improving processing efficiency and facilitating operation.

[0033] like Figure 1 , Figure 2As shown, a first motor 13 is fixedly installed on one side of the mounting column 3, and the output shaft of the first motor 13 is fixedly connected to the second gear 14. A mounting bracket is fixedly installed on one side of the mounting plate 2, and the mounting bracket is rotatably connected to the second gear 14. A second motor 12 is fixedly installed on one side of the slide plate 10, and the output shaft of the second motor 12 is fixedly connected to the rotating roller 11. A pull plate 17 is slidably installed on one side of the bottom of the mounting plate 2, and one side of the pull plate 17 is fixedly connected to the guide block 19. When the pull plate 17 is pulled, the guide block 19 is no longer in contact with the slide plate 10, and the rotating roller 11 is no longer pressing against the rotating roller 11. A second spring 22 is fixedly installed on one end of the connecting rod 9, and one end of the second spring 22 is fixedly connected to the clamping plate 21.

[0034] The working principle of this embodiment is as follows: A shaft-like workpiece is placed inside the sleeve 4. The electric telescopic rod 6 is activated, causing the connecting ring 7 to move as it retracts. Since one end of the guide rod 8 is hinged to a connecting rod 9, when the connecting ring 7 retracts, the connecting rod 9 moves downwards, fixing the shaft-like workpiece placed inside the sleeve 4. This activates the first motor 13, whose output shaft drives the second gear 14 to rotate. The second gear 14 then drives the first gear 15 to rotate, thereby causing the fixed shaft-like workpiece inside the sleeve 4 to rotate. When it is necessary to remove the fixation of the shaft-like workpiece, simply extend the electric telescopic rod 6 and activate the second motor 12. The output shaft of the second motor 12 drives the rotating roller 11 to rotate, enabling the shaft-like workpiece to rotate while also moving horizontally, improving processing efficiency and facilitating operation.

[0035] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
