Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a simple rotatable indexing tooling fixture. Background Technology

[0002] In production, it is common to encounter workpieces that require machining a set of surfaces that are evenly distributed at a certain angle or distance, and whose shapes and sizes are the same. For example, drilling a set of equally divided holes, milling a set of equally divided grooves, or machining polyhedra. In order to complete the machining of equally divided surfaces of the workpiece in one clamping, the workpiece is first clamped by a fixture, and then the fixture and the workpiece are rotated by a certain angle or moved by a certain distance to change the position of the machined surface. The device that achieves the above indexing requirements is called an indexing device.

[0003] Currently, CNC milling machines are commonly used to process rotating parts. To achieve the above indexing requirements, if CNC milling machines are used directly, there are many processes, such as turnover and clamping and positioning processes, which result in long processing time and low efficiency. If traditional universal indexing heads are used, there are problems such as the universal indexing head being bulky, large in size, and having a complex indexing process.

[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model, and should not be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0026] Please refer to the following: Figures 1-4 A simple rotatable indexing fixture includes a base 1, with fixed disks 2 fixedly connected to both sides of the top of the base 1. A positioning component 3 is provided inside the fixed disk 2. A turntable 4 is rotatably provided on one side of the fixed disk 2. A fixed frame 5 is fixedly connected to one side of the turntable 4. Two clamping plates 6 are slidably provided on the inner wall of the fixed frame 5. A pointer 7 is fixedly connected to the top of the turntable 4. The surface of the fixed disk 2 is provided with a scale that works in conjunction with the pointer 7.

[0027] The workpiece is placed in the fixed frame 5 on one side of the two turntables 4. The workpiece is clamped by the two clamping plates 6 moving towards each other. An arc-shaped groove is provided on one side of the clamping plate 6, which can fix the shaft-shaped or square workpiece, improving its applicability. The turntable 4 rotates on one side of the fixed plate 2, which drives the workpiece to adjust its angle. When the turntable 4 rotates, its top pointer 7 slides on the surface of the fixed plate 2. The angle of the workpiece can be known according to the scale pointed to by the pointer 7.

[0028] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the positioning component 3 includes a rotating shaft 31 rotatably mounted on the inner wall of the fixed disk 2. One end of the rotating shaft 31 is fixedly connected to the axis of the turntable 4. A positioning block 32 is fixedly connected to the outer side of the rotating shaft 31. A positioning screw 33 is fixedly connected to the inner wall of the positioning block 32. An annular groove 34 is opened on the inner wall of the fixed disk 2 to cooperate with the positioning screw 33. A fixing nut 35 is screwed onto the positioning screw 33.

[0029] refer to Figure 2 As shown, a connecting rod 8 is fixedly connected to the top of the positioning block 32, and a handle 9 is fixedly connected to the top of the connecting rod 8.

[0030] The handle 9 and connecting rod 8 drive the positioning block 32 to rotate, which in turn drives the rotating shaft 31 to rotate the turntable 4. When the rotating shaft 31 rotates, the positioning screw 33 in the positioning block 32 rotates in the annular groove 34. After adjusting the workpiece angle, the positioning block 32 is fixed by tightening the fixing nut 35, so that one side of the positioning block 32 fits tightly with one side of the fixing plate 2, thereby fixing the rotating shaft 31 and achieving the effect of convenient and quick positioning of the workpiece.

[0031] refer to Figure 3 As shown, a bidirectional lead screw 10 is rotatably installed at the bottom of the fixed frame 5. Two moving rods 11 are screwed onto the bidirectional lead screw 10. One side of the moving rod 11 is fixedly connected to one side of the clamping plate 6. A knob 12 is fixedly connected to one end of the bidirectional lead screw 10.

[0032] The top of the fixed frame 5 is provided with a guide groove 13 that works with the moving rod 11. The top of the moving rod 11 is fixedly connected with a positioning plate 14. A bolt is screwed into the positioning plate 14, and the bottom end of the bolt abuts against the top of the fixed frame 5.

[0033] The double-acting lead screw 10 can be easily rotated by the knob 12. When the double-acting lead screw 10 rotates, it drives the two moving rods 11 to move towards each other. The moving rods 11 drive the clamping plate 6 to move, thereby clamping and fixing the workpiece. When the moving rods 11 move, their tops slide in the guide groove 13, which guides and limits the moving rods 11, improving the stability of the moving rods 11 during movement. After the workpiece is clamped, the bolts in the positioning plate 14 are tightened to position the positioning plate 14, thereby fixing the clamping plate 6 and improving the clamping stability of the clamping plate 6.

[0034] refer to Figure 4 As shown, a movable block 15 is fixedly connected to one end of the positioning screw 33, and a movable groove 16 is connected to one side of the annular groove 34. The outer side of the movable block 15 slides in the movable groove 16.

[0035] When the positioning screw 33 slides in the annular groove 34, the moving block 15 at one end of the positioning screw 33 slides synchronously in the moving groove 16 to guide and limit the positioning screw 33.

[0036] The working principle of the simple rotatable indexing fixture provided by this utility model is as follows:

[0037] In use, the workpiece is placed in the fixed frame 5 on one side of the two turntables 4. The workpiece is clamped by the two clamping plates 6 moving towards each other. The clamping plates 6 have an arc-shaped groove on one side, which can fix shaft-shaped or square workpieces, improving applicability. The handle 9 and the connecting rod 8 drive the positioning block 32 to rotate, so that the rotating shaft 31 drives the turntable 4 to rotate, thereby adjusting the angle of the workpiece. The pointer 7 on the top of the turntable 4 slides on the surface of the fixed plate 2. The angle of the workpiece can be determined according to the scale pointed to by the pointer 7. After adjusting the angle of the workpiece, the positioning block 32 is fixed by tightening the fixing nut 35, so that one side of the positioning block 32 fits tightly with one side of the fixed plate 2, thereby fixing the rotating shaft 31 and achieving the effect of convenient and quick positioning of the workpiece.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
