Technical Field

[0001] This utility model relates to the technical field of workpiece positioning devices, specifically a rapid rotation angle positioning device. Background Technology

[0002] A workpiece is the object of machining. It can be a single part or a combination of several parts fixed together. When a workpiece is manufactured, it needs to be clamped and positioned for further processing. In order to ensure machining accuracy, the workpiece must first occupy a correct position, that is, be positioned, and then be clamped and fixed.

[0003] Before machining, existing workpieces often need to be positioned and clamped. However, traditional workpiece positioning and clamping mechanisms are difficult to quickly and effectively correct the workpieces. In actual use, it is necessary to repeatedly position the workpiece plane or groove features, which greatly increases the correction time and significantly reduces the machining efficiency of the workpieces. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rapid rotation angle positioning device, which solves the problem that existing workpieces often need to be positioned and clamped before tooling processing. However, traditional workpiece positioning and clamping mechanisms are difficult to quickly and effectively correct the workpieces. In actual use, it is necessary to repeatedly position the workpiece plane or groove features, which greatly increases the workpiece correction time and significantly reduces the workpiece processing efficiency.

[0005] This utility model provides the following technical solution: a rotation angle rapid positioning device, including an auxiliary worktable, on which a plurality of connecting limiting grooves are evenly opened, and two machining center V-blocks are symmetrically arranged on the top of the auxiliary worktable, and two side pads are symmetrically arranged on the inner sidewalls of the machining center V-blocks, and two fixing screws are symmetrically arranged on both sides of the top of the machining center V-blocks.

[0006] A contact plate is provided above the V-block of the machining center. Both ends of the contact plate are penetrated by the fixing screw. A workpiece contact block is provided in the middle of the bottom end of the contact plate. A connecting washer and a fixing nut are sleeved on the top of the fixing screw.

A mounting through hole is opened in the middle of the machining positioning cylinder. A positioning contact screw is inserted through the mounting through hole. A positioning contact ball is provided at the end of the positioning contact screw.

[0007] Preferred technical solution 1: A first fastening nut is fitted on the positioning and abutting screw, and a second fastening nut is fitted on the end of the positioning and abutting screw.

[0008] Preferred technical solution 2: Two limiting connecting blocks are symmetrically arranged on both sides of the bottom end of the V-shaped block of the machining center, and the limiting connecting blocks are slidably inserted into the connecting limiting groove.

[0009] Preferred technical solution 3: A V-shaped groove is provided in the middle of the V-shaped block of the machining center.

[0010] This solution enables the V-block of the machining center to more easily provide contact support to the workpiece body.

[0011] Preferred technical solution four: The bottom end face of the workpiece contact block is a curved arc shape that facilitates clamping and fixing.

[0013] Preferred technical solution five: A washer is sleeved on the positioning and contacting screw, and the washer is located on the side of the second fastening nut.

[0014] This solution enables the positioning screw to be firmly fixed to the machining positioning cylinder by the mutual contact between the second fastening nut and the first fastening nut.

[0015] Compared with the prior art, this utility model provides a rapid positioning device for rotation angle, which has the following beneficial effects:

[0016] (1) This utility model provides two machining center V-blocks on the top of the auxiliary worktable. The two machining center V-blocks can support the bottom of the workpiece body. A cross plate is provided above the machining center V-blocks, and a workpiece abutment block is provided at the bottom of the cross plate. The workpiece abutment block can be driven by the user rotating the fixing nut, so that the two ends of the cross plate are abutted and the workpiece abutment block can be firmly abutted against the upper part of the workpiece body. A positioning abutment screw is provided on the machining positioning cylinder, and a positioning abutment ball is provided at the end of the positioning abutment screw.

[0022] Please see Figure 1-4 ,

[0023] Example 1: A rapid positioning device for rotation angle includes an auxiliary worktable 1. Several connecting and limiting grooves 2 are evenly provided on the auxiliary worktable 1. Two machining center V-blocks 3 are symmetrically arranged on the top of the auxiliary worktable 1. Two side pads 4 are symmetrically arranged on the inner sidewalls of the machining center V-blocks 3. Two fixing screws 5 are symmetrically arranged on both sides of the top of the machining center V-blocks 3.

[0024] A contact plate 6 is provided above the V-block 3 of the machining center. Both ends of the contact plate 6 are penetrated by fixing screws 5. A workpiece contact block 7 is provided in the middle of the bottom end of the contact plate 6. A connecting washer 8 and a fixing nut 9 are sleeved on the top of the fixing screw 5. The fixing nut 9 is located above the connecting washer 8. Workpiece bodies 10 are provided on the two V-blocks 3 of the machining center. Both sides of the workpiece body 10 are abutted by the side pads 4. Several mounting screw holes 11 are evenly opened on the top of the auxiliary worktable 1. A machining positioning cylinder 12 is provided on the front side of the workpiece body 10. A connecting screw 13 is provided at the bottom end of the machining positioning cylinder 12.

[0025] The connecting screw 13 is inserted into the mounting screw hole 11. The middle part of the machining positioning cylinder 12 is provided with a mounting through hole 14. A positioning abutment screw 15 is inserted through the mounting through hole 14. A positioning abutment ball 16 is provided at the end of the positioning abutment screw 15. A first fastening nut 17 is sleeved on the positioning abutment screw 15. A second fastening nut 18 is sleeved at the end of the positioning abutment screw 15. Two limiting connecting blocks 19 are symmetrically arranged on both sides of the bottom end of the machining center V-block 3. The limiting connecting blocks 19 are slidably inserted into the connecting limiting groove 2.

[0026] Example 2: The difference between this example and Example 1 is that the V-shaped groove is provided in the middle of the V-shaped block 3 of the machining center.

[0027] This makes it easier for the V-block 3 of the machining center to resist and support the workpiece body 10.

[0028] Example 3: The difference between this example and Example 1 is that the bottom end face of the workpiece contact block 7 is a curved arc shape that facilitates clamping and fixing.

[0029] This allows the workpiece contact block 7 to fit more closely and contact the upper surface of the workpiece body 10.

[0030] Example 4: The difference between this example and Example 1 is that a washer is fitted on the positioning contact screw 15, and the washer is located on the side of the second fastening nut 18.

[0031] This allows the positioning screw 15 to be firmly fixed to the machining positioning cylinder 12 by the mutual contact between the second fastening nut 18 and the first fastening nut 17.

[0032] In this embodiment, the existing workpieces often need to be positioned and clamped before tooling processing. However, traditional workpiece positioning and clamping mechanisms are difficult to quickly and effectively correct the workpieces. In actual use, it is necessary to repeatedly position the workpiece plane or groove and other features, which greatly increases the correction time of the workpiece and greatly reduces the processing efficiency of the workpiece.

[0033] In summary, in specific implementation, when the user needs to position and clamp the workpiece body 10 before tooling, the user first places the workpiece body 10 into the middle of the two machining center V-blocks 3, and two side pads 4 are symmetrically arranged on both sides of the inner wall of the machining center V-blocks 3, so that the two sides of the workpiece body 10 can be more stable by the resistance of the side pads 4.

[0034] Next, both ends of the contact plate 6 are simultaneously fitted onto the fixing screw 5, so that the workpiece contact block 7 at the bottom of the contact plate 6 fits and is locked onto the upper end of the workpiece body 10. The user then fits the fixing nut 9 onto the top of the fixing screw 5. By tightening the fixing nut 9, the upper parts of both ends of the contact plate 6 are brought into contact, so that the workpiece contact block 7 on the contact plate 6 can be fixed against the top of the workpiece body 10, and the workpiece body 10 is stably clamped on the V-block 3 of the machining center.

[0035] Finally, by rotating the connecting screw 13 at the bottom of the machining positioning cylinder 12, the positioning contact ball 16 at the end of the positioning contact screw 15 inserted on the machining positioning cylinder 12 can be located at the end of the workpiece body 10. By adjusting the position of the positioning contact screw 15 inserted in the mounting through hole 14, the positioning contact ball 16 at the end of the positioning contact screw 15 can abut against the end of the workpiece body 10, thereby completing the positioning and clamping of the workpiece body 10. This allows the user to quickly and conveniently position and clamp the workpiece body 10 that needs to be processed, without having to perform multiple repeated positioning operations, greatly reducing the workpiece calibration time and improving the workpiece processing efficiency.
