[0029] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a simple clamping mechanism, including a base 1, a ball 2, an adjusting component 3, a fastener 4, and a clamping seat 5 with a triangular groove 51. The side wall of the clamping seat 5 is provided with a side through hole 52 communicating with the triangular groove 51. The fastener 4 is inserted into the side through hole 52, and one end of the fastener 4 extends into the triangular groove 51 and is used to fix the workpiece 100 to be processed in the triangular groove 51. It can be understood that the fastener 4 includes, but is not limited to, ball-head screws, bolts, etc., and the side through hole 52 communicates with one side of the triangular groove 51. The workpiece 100 to be processed includes, but is not limited to, a cylinder, etc.

[0031] The sphere 2 is installed between the base 1 and the clamp 5; the adjusting assembly 3 is installed on the base 1 and connected to the clamp 5, and is used to adjust the tilt angle between the clamp 5 and the base 1. Understandably, the opposite ends of the sphere 2 abut against the center portion of the clamp 5 and the center component of the base 1, respectively, so that the clamp 5 can rotate around the sphere 2.

[0032] In this utility model, the clamping base 5 is provided with a triangular groove 51 and a side through hole 52 communicating with the triangular groove 51. The fastener 4 is installed in the side through hole 52. By adjusting the depth of the fastener 4 inserted into the triangular groove 51, the fastener 4 can press and fix the workpiece 100 to be processed in the triangular groove 51. The workpiece 100 to be processed can be fixed in the triangular groove 51 by one fastener 4. The disassembly and assembly operation between the workpiece 100 to be processed and this simple clamping mechanism is simple.

[0033] Furthermore, the sphere 2 is installed between the base 1 and the clamp 5, and the adjusting component 3 is installed on the base 1 and connected to the clamp 5. The adjusting component 3 allows the clamp 5 to rotate around the sphere 2, thereby adjusting the tilt angle between the clamp 5 and the base 1. In other words, the installation angle of the workpiece 100 on this simple clamping mechanism is achieved. In this invention, the simple clamping mechanism has a simple structure, low manufacturing cost, and is easy to operate.

[0034] In one embodiment, such as Figure 1As shown, the cross-section of the triangular groove 51 is an isosceles triangle. The side through hole 52 connects to the side wall corresponding to the base of the triangular groove 51. The fastener 4 is used to press the workpiece 100 to be processed against the adjacent side walls corresponding to the adjacent two sides of the triangular groove 51. Understandably, the fastener 4 can move the workpiece 100 towards the apex of the triangular groove 51 until the fastener 4 presses the workpiece 100 into the triangular groove 51, and the workpiece 100 abuts against the two adjacent inner walls of the triangular groove 51. In this embodiment, the isosceles triangular groove 51 improves the stability of the fastener 4 pressing the workpiece 100 into the triangular groove 51. Furthermore, the axis of the side through hole 52 coincides with the perpendicular bisector of the isosceles triangle.

[0035] In one embodiment, such as Figure 1 As shown, the clamping base 5 is also provided with three rounded chamfered grooves 55, which are respectively located at the three corners of the triangular groove 51. The cross-section of the triangular groove 51 is an isosceles triangle, and the corners of the isosceles triangle are rounded chamfers. The clamping base 5 can be directly drilled using a CNC machine tool, which is fast and low-cost. If the included angle of the triangular groove 51 is directly made into an included angle formed by two hypotenuses, electrical discharge machining is required when machining the triangular groove 51, which is costly.

[0036] In one embodiment, such as Figure 1 As shown, one end of the fastener 4 that extends into the triangular groove 51 is a tapered end (not shown in the figure). The tapered end is used to fix the workpiece 100 to be processed in the rounded chamfered groove 55 of the triangular groove 51. It can be understood that if the corner of the triangular groove 51 is made into a rounded chamfered groove 55, when some workpieces 100 with smaller cross-sections (cylindrical electrodes, etc.) are fixed in the triangular groove 51, the tapered end of the fastener 4 can push the workpiece 100 to be processed into the rounded chamfered groove 55.

[0037] In one embodiment, such as Figure 1 and Figure 2 As shown, the clamp 5 has a first arc-shaped groove 53 at the end opposite to the triangular groove 51, and the base 1 has a second arc-shaped groove 11 at the end facing the clamp 5. The sphere 2 is installed in the first arc-shaped groove 53 and the second arc-shaped groove 11. Understandably, the top of the sphere 2 is located in the second arc-shaped groove 11, the top of the sphere 2 is located in the first arc-shaped groove 53, and the middle part of the sphere 2 is located between the clamp 5 and the base 1. This allows the clamp 5 to rotate around the sphere 2, while ensuring the stability of the sphere 2 installed between the base 1 and the clamp 5.

[0038] In one embodiment, such as Figure 1 and Figure 2 As shown, the clamp 5 is provided with a first connecting hole 54, a second connecting hole, a third connecting hole and a fourth connecting hole at one end facing the base 1, which surround the first arc-shaped groove 53; it can be understood that the first connecting hole 54, the second connecting hole, the third connecting hole and the fourth connecting hole are all located at the bottom of the clamp 5.

[0041] Specifically, by adjusting the depth of the first adjusting member 31 inserted into the first connecting hole 54, or by adjusting the depth of the second adjusting member inserted into the second connecting hole, or by adjusting the depth of the third adjusting member inserted into the third connecting hole, or by adjusting the depth of the fourth adjusting member inserted into the fourth connecting hole, the clamp 5 can rotate around the sphere 2. In this embodiment, the simple clamp mechanism has a simple structure and is easy to adjust.

[0042] In one embodiment, the line connecting the first connecting hole 54 and the third connecting hole is perpendicular to the line connecting the second connecting hole and the fourth connecting hole; it can be understood that the line connecting the first connecting hole 54 and the third connecting hole, as well as the line connecting the second connecting hole and the fourth connecting hole, both pass through the center of the first arc-shaped groove 53.

[0043] The line connecting the first through hole 12 and the third through hole is perpendicular to the line connecting the second through hole and the fourth through hole. Understandably, the lines connecting the first through hole 12 and the third through hole, as well as the lines connecting the second through hole and the fourth through hole, all pass through the center of the second arc-shaped groove 11. In this embodiment, the first adjusting member, the second adjusting member, the third adjusting member, and the fourth adjusting member are respectively installed in the front, back, left, and right directions of the base 1, thereby allowing adjustment of the tilt angle of the clamp 5 from these four directions.
