Description

Technical Field

[0001] This utility model relates to the field of milling machine cylindrical workpiece clamping and positioning technology, specifically a rapid positioning device for milling cylindrical workpieces. Background Technology

[0002] Milling machine cylindrical workpiece clamping and positioning refers to the process of firmly fixing a cylindrical workpiece on the milling machine table and placing it in an accurate machining position during the milling process to ensure machining accuracy and stability. This process usually requires the use of specific fixtures, such as three-jaw chucks, four-jaw chucks, center clamping devices, or special cylindrical workpiece fixtures. When clamping and positioning, it is essential to ensure that the axis of the workpiece maintains an appropriate spatial relationship with the movement direction of the milling machine spindle or machining tool, such as perpendicular or parallel, depending on the machining requirements.

[0003] Currently, when milling machines clamp cylindrical workpieces, manual positioning is required before the clamping mechanism can be manually operated, which is very cumbersome and affects the processing efficiency of the milling machine.

[0004] Therefore, a rapid positioning device for milling cylindrical workpieces is proposed to solve the above problems. Utility Model Content

[0010] Furthermore, the motor compartment is equipped with a forward and reverse motor, the top of the motor compartment is equipped with a motor shaft connected to the output end of the forward and reverse motor, and the side of the motor compartment is provided with a heat dissipation groove for motor heat dissipation.

[0011] Through the above technical solution, the motor shaft can rotate in both directions on the top of the motor compartment under the drive of the forward and reverse motors.

[0012] Furthermore, a support cylinder is installed on the clamping mechanism. The inner side of the support cylinder is sleeved on the outside of the motor shaft with a gap. The bottom circular plate of the support cylinder is fixed to the top of the motor compartment by bolts. A cross cover is fixedly installed on the top of the support cylinder. A circular hole communicating with the inside of the support cylinder is opened at the center of the top of the cross cover.

[0013] With the above technical solution, the motor shaft can rotate inside the support cylinder, and the motor shaft is connected to the outside through the round hole on the cross cover.

[0014] Furthermore, the square sleeves on the top four directions of the cross cover are provided with limiting grooves, the bottom square plate of the clamp plate is slidably connected to the inner side of the square sleeve on the cross cover, a sliding rod that is slidably connected to the limiting groove is installed on the bottom square plate of the clamp plate, and anti-slip texture is provided on the top inner side of the clamp plate.

[0015] Through the above technical solution, the clamping plate can slide back and forth within the length range of the top limiting groove of the cross cover using the slide rod.

[0016] Furthermore, a support column is installed at the top center of the adjusting plate, and a circular feeding plate is installed on the top of the support column.

[0018] Furthermore, the adjustment plate is evenly provided with four arc-shaped grooves, and the slide rod on each clamp plate is slidably connected to a corresponding arc-shaped groove on the adjustment plate. The top of the slide rod has two limiting plates located on the top edge and bottom edge of the arc-shaped groove, respectively.

[0019] Through the above technical solution, the slide rod can avoid falling off from the arc groove. At the same time, when the adjusting plate rotates, it can drive the four slide rods to slide in the limiting groove through the arc groove, thereby driving the four clamping plates to move simultaneously.

[0020] Furthermore, a connecting shaft is installed at the bottom center of the adjusting plate. The adjusting plate is located at the top of the cross cover, and the connecting shaft passes through the round hole at the top of the cross cover into the support cylinder and connects to the motor shaft.

Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

The cylindrical workpiece is placed on the loading plate 33, and the four clamping plates 25 are simultaneously moved towards the center of the circle by adjusting the adjusting plate 3 to quickly clamp the cylindrical workpiece and automatically center and position it. It can be used for clamping and positioning cylindrical workpieces of various sizes, effectively improving the processing efficiency of the milling machine.

[0034] Example 2

[0035] Please see Figure 1-2 Based on embodiment 1, this embodiment further specifies that the square sleeves on the top four directions of the cross cover 22 are provided with limiting grooves 23. The bottom square plate of the clamping plate 25 is slidably connected to the inner side of the square sleeve on the cross cover 22. A sliding rod 24 that is slidably connected to the limiting groove 23 is installed on the bottom square plate of the clamping plate 25. Anti-slip texture is provided on the top inner side of the clamping plate 25. The clamping plate 25 can be limited and slid inside the square sleeve on the cross cover 22 through the sliding rod 24, and the anti-slip texture on the clamping plate 25 can better clamp the cylindrical workpiece.

[0036] Example 3

[0037] Please see Figure 2-3 Based on Embodiment 1, this embodiment further specifies that a support column 32 is installed at the top center of the adjustment plate 3, and a circular feeding plate 33 is installed on the top of the support column 32. Multiple connecting blocks are connected at equal intervals between the bottom edge of the feeding plate 33 and the top edge of the adjustment plate 3. The bottom of the clamping surface of the clamping plate 25 is flush with the top of the feeding plate 33. The feeding plate 33 can support the cylindrical workpiece, and the clamping surface of the clamping plate 25 can clamp the cylindrical workpiece when it moves in the direction of the center of the feeding plate 33.

[0038] Example 4

[0039] Please see Figure 1-3 Based on Embodiment 1, this embodiment further specifies that four arc-shaped grooves 31 are evenly provided on the adjusting plate 3. The sliding rod 24 on each clamping plate 25 is slidably connected to a corresponding arc-shaped groove 31 on the adjusting plate 3. The top of the sliding rod 24 has two limiting plates located on the top edge and bottom edge of the arc-shaped groove 31, respectively. The limiting plates on the sliding rod 24 can prevent the sliding rod from separating from the arc-shaped groove 31. When the adjusting plate 3 rotates, it can drive the four clamping plates 25 to move simultaneously towards the center of the material plate 33 through the four arc-shaped grooves 31, thereby enabling the clamped cylindrical workpiece to be automatically centered and positioned.

[0040] Example 5

[0041] Please see Figure 1-4 Based on embodiment 1, this embodiment further specifies that a connecting shaft 34 is installed at the bottom center of the adjusting plate 3. The adjusting plate 3 is located at the top of the cross cover 22. The connecting shaft 34 passes through the round hole at the top of the cross cover 22 and enters the support cylinder 21 to connect with the motor shaft 12. The motor shaft 12 drives the connecting shaft 34 to rotate in both directions, so that the adjusting plate 3 can rotate in both directions, thereby enabling the four clamping plates 25 to quickly clamp and release the cylindrical workpiece.

[0042] Working principle: When using this positioning device for cylindrical workpieces on a milling machine, the bottom of the cylindrical workpiece is first placed on the loading plate 33. Then, the forward and reverse motors are started, driving the motor shaft 12 to rotate clockwise. The motor shaft 12 drives the adjusting plate 3 to rotate clockwise through the connecting shaft 34. Since the slide rods 24 are slidably installed in the arc grooves 31 on the adjusting plate 3, the clockwise rotation of the adjusting plate 3 drives the four slide rods 24 to move simultaneously towards the center. Because the slide rods 24 are connected to the clamping plates 25, the four clamping plates 25 move simultaneously under the drive of the slide rods 24 to clamp the cylindrical workpiece and can be centered during the clamping process. The range of movement of the four clamping plates 25 can accommodate cylindrical workpieces of various sizes, effectively improving the processing efficiency of the milling machine.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
