Description

Technical Field

[0001] The utility model relates to the technical field of shaft processing and positioning, in particular to a shaft workpiece processing and positioning device. Background Art

[0002] Shaft workpieces are an indispensable and important component of mechanical equipment in modern industrial technology. The positioning device during the processing of shaft workpieces is a key link to ensure processing accuracy and stability.

[0003] Existing machining and positioning devices for shaft workpieces mostly rely on two-point positioning and clamping. However, this two-point clamping method has a high dependence on the size and shape of the workpiece. At the same time, in order to ensure the stability of the workpiece during machining, a large stress usually needs to be applied during the clamping process, which may cause damage to the workpiece surface. For this reason, we propose a machining and positioning device for shaft workpieces. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See attached Figure 1-3A shaft workpiece processing positioning device comprises a base 1, on which a bottom clamp block 2, a positioning rod 3 and a movable rod 5 are arranged. The bottom clamp block 2, the positioning rod 3 and the movable rod 5 are arranged in pairs, and the positioning rod 3 and the movable rod 5 are arranged at both ends of the bottom clamp block 2. A top clamp plate 4 is hinged on the top of the positioning rod 3. A notch 41 for matching the movable rod 5 is arranged at one end of the top clamp plate 4 away from the positioning rod 3. The top of the movable rod 5 is a threaded rod. A nut 6 is threadedly connected to the outer wall of the threaded rod. A side positioning plate 7 is arranged between the top clamp plate 4 and the nut 6. One side of the side positioning plate 7 is provided with a pair of U-shaped positioning ends 71 ​​which are sleeved on the top of the movable rod 5 and cooperate with the nut 6. The workpiece is placed on the bottom clamp 2, and then the side positioning plate 7 is moved so that the side positioning plate 7 abuts against one side of the workpiece, and then the nut 6 is tightened so that the top clamp 4 presses the top of the workpiece. At this time, the workpiece is clamped at multiple points by the bottom clamp 2, the top clamp 4 and the side positioning plate 7. The clamping force of the multi-point clamping is stable, and no excessive stress is generated on the workpiece, which helps to ensure the stability of the processing quality.

[0024] In this embodiment, a limiting plate 42 is provided on the top clamping plate 4 to abut against the side wall of the side positioning plate 7. The limiting plate 42 limits the two sides of the side positioning plate 7 to prevent the side positioning plate 7 from deviating and affecting the clamping stability.

[0025] In this embodiment, the bottom of the movable rod 5 is hinged to the base 1, and the top of the movable rod 5 passes through the slot 41. The movable rod 5 deflects outward around the axis hinged to the base 1, and the top clamp 4 is rotated around the hinge axis with the positioning rod 3. At this time, large shaft parts or irregular shaft parts that need to be clamped can be placed on the bottom clamp block 2 for clamping, which greatly improves the practicability of the device.

[0026] In this embodiment, a side clamping block 72 for abutting against a side wall of the workpiece is provided on a side of the side positioning plate 7 away from the U-shaped positioning end 71 , thereby increasing the clamping force of the side positioning plate 7 on the workpiece.

[0027] In this embodiment, V-shaped clamping openings are provided inside the bottom clamping block 2 and the side clamping block 72. The V-shaped structure is not limited to the specific shape of the workpiece, thereby improving the fastening force and compatibility of the clamp.

[0028] In this embodiment, the length of the U-shaped positioning end 71 is greater than the length of the movable rod 5. The U-shaped positioning end 71 is sleeved on the movable rod 5 and can move left and right, so as to facilitate clamping of workpieces of different thicknesses.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
