Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

In the present embodiment, as shown in fig. 1, the first clamping assembly 2 and the second clamping assembly 3 are disposed opposite to each other on the upper surface 11 of the substrate 1, and a clamping station (not shown) for clamping the workpiece 100 is formed between the first clamping assembly 2 and the second clamping assembly 3, and at the same time, the first clamping assembly 2 and the second clamping assembly 3 are also slidable in the opposite direction to each other.
Next, in the present embodiment, as shown in fig. 2, the driver 4 is provided on the lower surface 12 of the substrate 1, and the driver 4 has the first driving end 41 and the second driving end 42 respectively in the direction in which the first clamping unit 2 and the second clamping unit 3 are opposed, while the first driving end 41 and the second driving end 42 are linearly movable in the direction in which they are opposed to each other.
In the present embodiment, as shown in fig. 2, the first transmission unit 5 and the second transmission unit 6 are both provided on the lower surface 12 of the base plate 1. The substrate 1 is formed with a through hole 13 corresponding to the first transmission assembly 5 and the second transmission assembly 6, the first transmission assembly 5 is connected to the first clamping assembly 2 through the through hole 13, and the second transmission assembly 6 is connected to the second clamping assembly 3 through the through hole 13.
In practical use, when the first driving end 41 and the second driving end 42 move to the first preset position in the opposite directions, the first clamping assembly 2 and the second clamping assembly 3 clamp the workpiece 100, and meanwhile, the first transmission assembly 5 and the second transmission assembly 6 respectively form self-locking. When the first driving end 41 and the second driving end 42 move to a second preset position in a direction away from each other, the first clamping assembly 2 and the second clamping assembly 3 release the workpiece 100, and the first transmission assembly 5 and the second transmission assembly 6 are unlocked.
It can be seen from the above description that, when the first driving end 41 and the second driving end 42 of the driving element 4 move to the first preset position respectively in the opposite directions, the first clamping assembly 2 and the second clamping assembly 3 can clamp the workpiece 100 together, and the first transmission assembly 5 and the second transmission assembly 6 can form self-locking respectively at this time, so that it is ensured that the first clamping assembly 2 and the second clamping assembly 3 can continuously generate a large clamping force on the workpiece 100, and the magnitude of the clamping force is independent of the driving force of the driving element 4, thereby improving the clamping stability of the workpiece 100. In addition, since only one driving member 4 is provided in the present embodiment, the workpiece 100 can be clamped, so that the entire tool is simpler in structure and easier to maintain.
Specifically, in the present embodiment, as shown in fig. 1, the first clamping assembly 2 includes: a first slide plate 21, a first push block 22 and a first clamping member 23. The first sliding plate 21 is slidably disposed on the upper surface of the substrate 1, specifically, a sliding rail (not shown) may be disposed on the upper surface of the substrate 1, and a sliding block (not shown) is disposed at the bottom of the first sliding plate 21, and the sliding of the first sliding plate 21 on the substrate 1 may be achieved through sliding fit between the sliding block and the sliding rail. Next, as shown in fig. 1, the first pushing block 22 is disposed on a side of the first sliding plate 21 away from the substrate 1, so that the first pushing block 22 can slide along with the first sliding plate 21.

In order to clamp the workpiece 100 by the first clamping side 232 of the first clamping member 23, in the present embodiment, the first sliding plate 21 and the first clamping member 23 are also connected to the first transmission assembly 5, so that the driving member 4 can drive the first sliding plate 21 and the first clamping member 23 to slide relative to the workpiece 100 through the first transmission assembly 5, thereby clamping and fixing the workpiece 100 in cooperation with the second clamping member 33.
Similarly, in the present embodiment, the corresponding second clamping assembly 3, as shown in fig. 1, specifically includes: a second slide plate 31, a second push block 32 and a second clamping member 33. The second sliding plate 31 is slidably disposed on the upper surface of the substrate 1, specifically, a sliding rail (not shown) may be disposed on the upper surface of the substrate 1, and a sliding block (not shown) is disposed at the bottom of the second sliding plate 31, and the sliding of the second sliding plate 31 on the substrate 1 may be achieved through the sliding fit between the sliding block and the sliding rail. Next, as shown in fig. 1, the second pushing block 32 is disposed on a side of the second sliding plate 31 away from the substrate 1, so that the second pushing block 32 can slide along with the second sliding plate 31. In addition, as shown in fig. 1, the second clamping member 33 is disposed opposite to the second push block 32 in the sliding direction of the second slide plate 31, and the second clamping member 33 includes: a second abutment side 331 arranged opposite the second pusher 32, a second clamping side 332 facing away from the second abutment side 331. In order to clamp the workpiece 100 by the second clamping side 332 of the second clamping member 33, in the present embodiment, the second sliding plate 31 and the second clamping member 33 are also connected to the second transmission assembly 6, so that the driving member 4 can drive the second sliding plate 31 and the second clamping member 33 to slide relative to the workpiece 100 through the second transmission assembly 6, thereby clamping and fixing the workpiece 100 in cooperation with the first clamping member 23.
In addition, in order to enable the first transmission assembly 5 to form self-locking after clamping the workpiece 100, as shown in fig. 2 and 3, a side portion of the first sliding plate 21 opposite to the base plate 1 protrudes to form a first protrusion 211 entering the through hole 13, and a side portion of the first clamping member 23 opposite to the base plate 1 protrudes to form a first protrusion 234 entering the through hole 13. In addition, in the present embodiment, as shown in fig. 3, the first transmission assembly 5 includes: a first T-shaped connector 51 and a first connector block 52.
Specifically, as shown in connection with fig. 3, the first transmission assembly 51 includes: the first vertical connecting arm 511 and the first horizontal connecting arm 512, wherein one end of the first vertical connecting arm 511 is connected to the first horizontal connecting arm 512, the other end of the first vertical connecting arm 511 is hinged to the first driving end 41, meanwhile, the first horizontal connecting arm 512 is located in the through hole 13, and one end of the first horizontal connecting arm 512, which is far away from the second transmission assembly 6, is hinged to the first protrusion 211. Further, the first connecting block 52 is disposed opposite to the first horizontal connecting arm 512 in the sliding direction of the first slide plate 21. In the present embodiment, as shown in fig. 3, the first connecting block 52 includes: the first connecting block body 521 hinged with the first protrusion 234, and a first protrusion 522 partially protruding from one side of the first connecting block body 521 opposite to the first horizontal connecting arm 512, wherein the first protrusion 522 is hinged with one end of the first horizontal connecting arm 512 opposite to the second transmission assembly 6.
Similarly, in order to enable the second transmission assembly 6 to form a self-locking after clamping the workpiece 100, as shown in fig. 2 and 4, the second sliding plate 31 partially protrudes with respect to one side of the base plate 1 to form a second protrusion 311 entering the through hole 13, and the second clamping member 33 partially protrudes with respect to one side of the base plate 1 to form a second protrusion 334 entering the through hole 13. Further, in the present embodiment, as shown in fig. 4, the second transmission assembly 6 includes: a second T-shaped connector 61 and a second connector block 62.
Specifically, as shown in fig. 4, the second transmission assembly 61 includes: a second vertical connecting arm 611 and a second horizontal connecting arm 612, wherein one end of the second vertical connecting arm 611 is connected to the second horizontal connecting arm 612, the other end of the second vertical connecting arm 611 is hinged to the second driving end 42, meanwhile, the second horizontal connecting arm 612 is located in the through hole 13, and one end of the second horizontal connecting arm 612, which is far away from the first transmission assembly 5, is hinged to the second protrusion 311. Further, the second connecting block 62 is disposed opposite to the second horizontal connecting arm 612 in the sliding direction of the second sliding plate 31. In the present embodiment, as shown in fig. 4, the second connection block 62 includes: a second connecting block body 621 hinged to the second protrusion 334, and a second protrusion 622 partially protruded from a side of the second connecting block body 621 opposite to the second horizontal connecting arm 612, and the second protrusion 622 is hinged to one end of the second horizontal connecting arm 612 opposite to the first transmission unit 5.
It can be seen that, during the process of clamping the workpiece 100, as shown in fig. 2, 3 and 4, the first driving end 41 and the second driving end 42 of the driving member 4 can be used to make the first driving end 41 and the second driving end 42 respectively perform linear motion toward the directions opposite to each other, and during the process of moving the first driving end 41 and the second driving end 42, the first sliding plate 21 and the second sliding plate 31 can be pulled to move relative to each other by the first horizontal connecting arm 512 of the first T-shaped connecting member 51 and the second horizontal connecting arm 612 of the second T-shaped connecting member 61 respectively until the first clamping member 23 and the second clamping member 33 can be pushed by the first pushing block 22 and the second pushing block 32 respectively, so as to complete the clamping and fixing of the workpiece 100. Meanwhile, in the process of moving the whole first T-shaped connecting member 51, as shown in fig. 3, by means of the hinged relationship between the first vertical connecting arm 511 and the first driving end 41, the hinged relationship between the first horizontal connecting arm 512 and the first protrusion 211, and the hinged relationship between the first horizontal connecting arm 512 and the first protrusion 522, the whole first T-shaped connecting member 51 can deflect towards the direction opposite to the driving member 4 until the hinged end formed by the first horizontal connecting arm 512 and the first protrusion 211, the hinged end formed by the first horizontal connecting arm 512 and the first protrusion 522, and the hinged end formed by the first connecting block body 521 and the first protrusion 234 are in the same straight line along the direction parallel to the substrate 1, so that the first transmission assembly 5 can be self-locked, i.e. the state shown in fig. 2. When the whole second T-shaped connecting member 61 is in the process of moving, as shown in fig. 4, by means of the hinged relationship between the second vertical connecting arm 611 and the second driving end 42, the hinged relationship between the second horizontal connecting arm 612 and the second protrusion 311, and the hinged relationship between the second horizontal connecting arm 612 and the second protrusion 622, the whole second T-shaped connecting member 61 can be deflected toward the direction opposite to the driving member 4 until the hinged end formed by the second horizontal connecting arm 612 and the second protrusion 611, the hinged end formed by the second horizontal connecting arm 612 and the second protrusion 622, and the hinged end formed by the second connecting block body 621 and the second protrusion 334 are in the same straight line along the direction parallel to the base plate 1, so that the second transmission assembly 6 can be self-locked, i.e. the state shown in fig. 2.
As can be seen from the above, by virtue of the self-locking of the first transmission assembly 5 and the second transmission assembly 6, the first clamping component 23 and the second clamping component 33 can be ensured to continuously clamp the workpiece 100, and the clamping stability of the workpiece 100 is ensured.
In addition, as shown in fig. 1, a first blocking edge 233 is formed by extending a side of the first clamping component 23 away from the substrate 1 horizontally in a direction opposite to the first pushing block 22, and the first blocking edge 233 abuts against a side of the first pushing block 22 away from the substrate 1, that is, abuts against a top of the first pushing block 22. Correspondingly, the second clamping component 33 is away from the substrate 1, and extends horizontally in a direction opposite to the second pushing block 32 to form a second rib 333, and the second rib 333 abuts against a side of the second pushing block 32 away from the substrate 1, that is, abuts against the top of the second pushing block 32. Therefore, as can be seen from the above, by the abutment of the first rib 233 against the top of the first push block 22 and the abutment of the second rib 333 against the top of the second push block 32, the first clamping component 23 and the second clamping component 33 can be positioned respectively, so that only a unique movement posture of the first clamping component 23 and the second clamping component 33 is ensured in the movement process, and the movement performance of the first clamping component 23 and the second clamping component 33 is improved.
Finally, it should be noted that in order to achieve the relative movement between the first driving end 41 and the second driving end 42 of the driver 4 in the present embodiment, as shown in fig. 2, in the present embodiment, the driver 4 includes: a cylinder 43, a first top plate 44, a second top plate 45, a first cylinder connection member, and a second cylinder connection member.
As shown in fig. 2, the air cylinder 43 is disposed on the lower surface of the substrate 1, and the air cylinder 43 includes: a cylinder 431, a first piston rod (not shown) and a second piston rod (not shown) disposed in the cylinder 431, while the first piston rod and the second piston rod are disposed opposite to each other in a direction in which the first clamping assembly 2 and the second clamping assembly 3 are opposite to each other. Meanwhile, the first top plate 44 is fixedly connected with the first piston, the second top plate 45 is fixedly connected with the second piston rod, and the corresponding first cylinder connector is the first driving end 41 and is disposed on the first top plate 44, and the second cylinder connector is the second driving end 42 and is disposed on the second top plate 45. It can be seen that the first top plate 44 and the second top plate 45 can respectively drive the first cylinder connecting member and the second cylinder connecting member to perform a linear motion relative to each other by the contraction motion of the first piston rod and the second piston rod in the cylinder 43.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
