Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The clamp locking mechanism shown includes: a power unit, a support unit and a clamping unit, the support unit includes a support plate 3 and a clamp placement plate 6, the clamp 5 is arranged on the clamp placement plate 6, the clamp placement plate 6 is arranged on the support plate 3, the clamping unit includes a pressing arm 8, a side connecting plate 9, a first hinged link 10 and a second hinged link 11, the side connecting plate 9 is arranged on the support plate 3, the first hinged link 10 is connected to the side connecting plate 9, the first hinged link 10 is provided with a bearing 12, the power output end of the power unit is connected to the second hinged link 11, a process bearing groove 16 is opened on the pressing arm 8, the bearing 12 is matched with the process bearing groove 16, the pressing arm 8 is hinged to the second hinged link 11, and a positioning pin is also provided on the clamp placement plate 6, which is matched with the clamp 5.
[0032] The above-mentioned clamp locking mechanism utilizes a power unit to drive the second hinged link 11 and the pressure arm 8 to realize lifting and lowering movement. At the same time, since a bearing 12 is provided on the first hinged link 10, and the bearing 12 is connected with the process bearing groove 16, during the movement of the pressure arm 8, the pressure arm 8 will be under the action of the process bearing groove 16 to realize locking and unlocking of the clamp 5, thereby improving the locking efficiency of the clamp 5 and realizing automatic locking. At the same time, locking can be achieved using a single power unit, saving procurement and maintenance costs, which is conducive to cost control.
[0033] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7As shown, in this embodiment, the clamp locking mechanism also includes a mechanism base 1, and the power unit and the support plate 3 are both arranged on the mechanism base 1; the mechanism base 1 provides stable support for the entire clamp locking mechanism, and the mechanism base 1 is a rectangular structure, which ensures the stability of the clamp locking mechanism during the working process. The pressure arms 8 are arranged in pairs, and the pressure arms 8 are arranged relative to each other. A movable groove corresponding to the pressure arm 8 is opened on the clamp placement plate 6, and the pressure arm 8 swings back and forth in the movable groove to achieve clamping and unlocking. At the same time, the movable groove also limits the swing range of the pressure arm 8. The clamp locking mechanism also includes a bearing rod, one end of the bearing rod is connected to the support plate 3, and the other end of the bearing rod is connected to the first hinge link 10. The inner ring of the bearing 12 is fixed on the bearing rod, and the outer ring of the bearing 12 rolls in the process bearing groove 16. The side connecting plates 9 are arranged in pairs at both ends of the first hinge link 10, with the purpose of connecting the first hinge link 10 to the support plate 3.
[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, in this embodiment, the clamp locking mechanism also includes a support column 4, one end of the support column 4 is connected to the mechanism base 1, and the other end of the support column 4 is connected to the clamp placement plate 6; the clamp locking mechanism also includes a pad 7, and the pad 7 is arranged at the connection between the support column 4 and the clamp placement plate 6; on the basis of the support plate 3, the support column 4 is added to further improve the stability of the clamp locking mechanism. At the same time, compared with directly connecting the support column 4 to the clamp placement plate 6, by setting the pad 7, the contact area between the pad 7 and the clamp placement plate 6 can be increased, so that the support of the support column 4 to the clamp placement plate 6 is more stable.
[0035] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, in this embodiment, the power unit is a cylinder 2, and the power output end of the cylinder 2 is connected to the second articulated link 11; the clamp locking mechanism also includes a cylinder connector 13, one end of the cylinder connector 13 is connected to the cylinder 2, and the other end of the cylinder connector 13 is connected to the second articulated link 11; a single cylinder 2 is used to drive the second articulated link 11 through the cylinder connector 13, so that the pressure arm 8 can lock and unlock the clamp 5 under the lifting action of the cylinder 2. The use of a single cylinder 2 can not only reduce procurement costs and reduce the cost of the automated production line, but also help to reduce the cost of subsequent equipment maintenance, and reduce the occupied space, saving space for the automated production line, and the cylinder 2 is a piston rod cylinder, which has a lower cost.
[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, in this embodiment, a hinge hole 14 is provided on the second hinged link 11, a hinge rod is provided on the hinge hole 14, and the pressure arm 8 is connected to the hinge rod; by connecting the pressure arm 8 to the hinge rod, during the up and down movement of the second hinged link 11, the pressure arm 8 will swing along the process bearing groove 16 with the hinge rod as the fixed rotation axis, thereby realizing the locking and unlocking of the clamp 5, and improving the stability of the swinging process of the pressure arm 8.
[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, in this embodiment, a locating pin hole 15 is provided on the clamp 5, and the locating pin hole 15 is matched with the locating pin; in the process of installing the clamp 5, the locating pin hole 15 is matched with the locating pin on the clamp placement plate 6 to realize the installation and positioning of the clamp 5, and the matching tolerance between the locating pin hole 15 and the locating pin is H7g6. Although there is a gap between the locating pin hole 15 and the locating pin, this is within the allowable range and will not affect the connection and positioning stability. By matching the locating pin hole 15 with the locating pin, and then using the pressure arm 8 to clamp the clamp 5, the clamp 5 is restricted from moving in all directions, achieving complete locking to meet the working requirements.
[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, in this embodiment, the design angle of the process bearing groove 16 is 150°; by the design angle of the process bearing groove 16 The angle of the pressing arm 8 should be 150° to ensure that the swinging posture of the pressing arm 8 can just lock or unlock the clamp 5 so that its motion trajectory coincides with the position of the pressing arm 8.
[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the support plate 3 is in a convex shape; by setting the support plate 3 in a convex shape, the material usage of the support plate 3 is reduced as much as possible on the basis of ensuring that the support plate 3 stably supports the fixture placement plate 6, saving costs. At the same time, due to the reduction in the use of materials, the floor space is also saved.
[0040] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5and Figure 7 As shown, in this embodiment, first, the clamp locking mechanism is in the unlocked state. At this time, the cylinder 2 pushes the cylinder connector 13 and the second hinged link 11 upwards. Since the bearing 12 is fixed in position, the outer ring of the bearing 12 rolls in the process bearing groove 16 on the pressing arm 8. Therefore, the pressing arm 8 swings along the process bearing groove 16 under the action of the cylinder 2, and the pressing ends of the two pressing arms 8 swing away from each other, and the clamp locking mechanism is unlocked; thereafter, the clamp 5 is installed on the clamp placement plate 6, and it is ensured that the locating pin hole 15 is matched with the locating pin, and then the clamp 5 is locked, and the cylinder 2 falls back downward, and the cylinder connector 13 and the second hinged link 11 drive the pressing arm 8 to descend, and the pressing arm 8 is in the cylinder 2. Under the action, it swings along the process bearing groove 16, and the pressing ends of the two pressure arms 8 swing in a direction close to each other until the clamp 5 is pressed, thereby achieving the fixation of the clamp 5. It should be noted that since the pressure arm 8 needs to press the clamp 5, the part of the clamp 5 that is in contact with the pressure arm 8 can be made of a high-strength and wear-resistant material to improve the service life of the clamp 5, and the interior of the process bearing groove 16 must be finely ground and polished to ensure that the bearing 12 can roll smoothly inside it. The above-mentioned clamp locking mechanism has been used in equipment for 3D detection of automotive control unit pins. In addition, it can also be applied to other application scenarios that require automatic locking of clamps and automated production lines.
[0041] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
