DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] Embodiment 1:

[0029] A clamp for efficiently clamping a connecting rod, such as Figures 1 to 8As shown, the connecting rod 3 includes a connecting rod body 1 and a connecting rod seat 2. The connecting rod body 1 and the connecting rod seat 2 are connected by a fastener, and the fastener is preferably a bolt, which passes through the connecting rod seat 2 and is threadedly connected to the connecting rod body 1.

[0030] A positioning protrusion is provided at the end of the connecting rod body 1, and a positioning groove is opened at the end of the connecting rod seat 2. The positioning protrusion is adapted to the positioning groove, and the positioning protrusion is inserted into the positioning groove, so as to further ensure the relative stability of the two and facilitate the installation of fasteners to connect the connecting rod body 1 and the connecting rod seat 2.

[0031] The clamp includes a support seat 4, a positioning seat 5 and a clamping assembly 6. The support seat 4 is used to support the connecting rod 3. Specifically, at least three supporting protrusions 9 are arranged on the support seat 4. The supporting protrusions 9 are all truncated cone-shaped, and the axis connecting line of the three supporting protrusions 9 is a triangular structure. The upper end surfaces of the three supporting protrusions 9 are abutted against the lower surface of the connecting rod body 1. The three supporting protrusions 9 support the connecting rod body 1 at three points, which not only can achieve stable support for the connecting rod body 1, but also through the contact between the three supporting protrusions 9 and the connecting rod body 1, the contact area is reduced, which can effectively reduce the wear on the connecting rod body 1.

[0032] A positioning clamp 51 is provided on the positioning seat 5, and the positioning clamp 51 is used to position the end of the connecting rod body 1. The positioning clamp 51 is opposite to the end of the connecting rod body 1. In the present embodiment, the positioning clamp 51 is in a "C" shape. By making the inner side wall of the positioning clamp 51 abut against the end of the connecting rod body 1, the position of the connecting rod body 1 is restricted to achieve the positioning of the connecting rod body 1. It should be noted that the positioning clamp 51 with a "C" shape can fit the shape of the end of the connecting rod body 1 more closely, so the positioning effect of the connecting rod body 1 is better, and the positioning clamp 51 with a "C" shape can position connecting rod bodies 1 of different sizes, and has a wider range of applications.

[0033] Furthermore, the positioning seat 5 is detachably arranged on the mounting seat 10, and the mounting seat 10 is installed on the support seat 4. Specifically, a guide groove 11 for guiding the positioning seat 5 is opened on the mounting seat 10, and the positioning seat 5 is arranged in the guide groove 11. A fixing bolt 12 is threadedly connected to the mounting seat 10, and the fixing bolt 12 extends into the guide groove 11 and is threadedly connected to the positioning seat 5. A limiting bolt 13 for limiting the positioning seat 5 is threadedly connected to the mounting seat 10, and the end of the limiting bolt 13 extends into the guide groove 11, and the end of the limiting bolt 13 abuts against the end of the positioning seat 5.

[0034] When adjusting the position of the locating seat 5, loosen it by rotating the fixing bolt 12, and then rotate the limit bolt 13 to adjust the length of the limiting bolt 13 extending into the guide groove 11, so that the locating seat 5 can move along the guide groove 11, and finally, rotate the fixing bolt 12 to make it extend into the guide groove 11 and be threadedly connected with the locating seat 5, thereby fixing the position of the locating seat 5, and accurately adjusting the position of the locating seat 5 to ensure that the locating clamp 51 can accurately position the end of the connecting rod body 1, and when the inner side wall of the locating clamp 51 is worn, it can be loosened by rotating the fixing bolt 12, so that the locating seat 5 can be removed for replacement.

[0035] A positioning portion 7 is provided on the support seat 4, and the positioning portion 7 is used to position the end of the connecting rod seat 2. Preferably, in this embodiment, there are two positioning portions 7 and the two are arranged opposite to each other. A positioning surface 71 is provided on the positioning portion 7, and the positioning surface 71 can be fitted with the outer wall of the connecting rod seat 2 to limit the position of the connecting rod seat 2 and realize the positioning of the connecting rod seat 2. Moreover, since the positioning surface 71 on the positioning portion 7 is fitted with the outer wall of the connecting rod seat 2, the positioning effect of the connecting rod seat 2 is better.

[0036] The connecting rod body 1 is positioned by the positioning clamp 51 and the connecting rod seat 2 is positioned by the positioning portion 7, thereby achieving accurate positioning of the connecting rod 3.

[0037] The clamping assembly 6 can press the connecting rod 3 onto the support seat 4. Preferably, in this embodiment, there are at least three clamping assemblies 6. On the surface of the connecting rod 3, the three clamping points of the three clamping assemblies 6 form a triangular structure, thereby ensuring that the surface of the connecting rod 3 is evenly stressed, and the connecting rod 3 can be pressed onto the support seat 4 more stably, thereby achieving stable clamping of the connecting rod 3.

[0038] Specifically, the clamping assembly 6 includes a driving member 61, a pressure block 62 and two connecting rods 63. The driving member 61 is preferably a cylinder. The output end of the driving member 61 is rotatably connected to the end of the pressure block 62. One end of the two connecting rods 63 is rotatably connected to the driving member 61, and the other ends of the two connecting rods 63 are rotatably connected to the middle of the pressure block 62. The two connecting rods 63 are respectively located on both sides of the pressure block 62. The driving member 61 is used to drive the pressure block 62 to move, so that the pressure block 62 can rotate around the connection point between it and the connecting rod 63.

[0039] The end of the pressure block 62 is provided with a protruding clamping portion 8, which is used to abut against the upper surface of the connecting rod body 1. By contacting the protruding clamping portion 8 with the upper surface of the connecting rod body 1, the contact area is reduced, which can effectively reduce the wear on the connecting rod body 1.

[0040] It should be noted that, by extending the output end of the driving member 61, the pressure block 62 is driven to rotate around the connection point between the pressure block 62 and the connecting rod 63 until the protruding clamping portion 8 on the pressure block 62 abuts against the upper surface of the connecting rod body 1. Conversely, by retracting the output end of the driving member 61, the pressure block 62 is driven to rotate around the connection point between the pressure block 62 and the connecting rod 63, and the protruding clamping portion 8 on the pressure block 62 is away from the upper surface of the connecting rod body 1.

[0041] A clamping unit includes a plurality of clamps arranged in an array. A single clamping assembly 6 can respectively clamp two adjacent connecting rod bodies 1 on corresponding supporting seats 4. It should be noted that a single clamping assembly 6 can respectively clamp two adjacent connecting rod bodies 1 on corresponding supporting seats 4. The overall structure is more compact, occupies less space, and is more efficient in clamping multiple connecting rods 3.

[0042] Embodiment 2:

[0043] The difference between the second embodiment and the first embodiment is that Fig. 9 As shown, the positioning clamp 51 has a "V"-shaped structure. It should be noted that the positioning clamp 51 with a "V"-shaped structure can fit the shape of the end of the connecting rod body 1 more closely, so the positioning effect of the connecting rod body 1 is better, and the positioning clamp 51 with a "V"-shaped structure can position connecting rod bodies 1 of different specifications and sizes, and has a wider range of applications.
