In some embodiments, referring to fig. 2 and 3, the clamping fixture 100 further includes a third supporting component 50, the third supporting component 50 includes a supporting member 51 and a positioning needle 52, the supporting member 51 is connected to one end of the driving rod 21 and protrudes from the substrate 11, the positioning needle 52 is connected to a side of the supporting member 51 facing the first supporting component, and the positioning needle 52 is used for being inserted into the workpiece 200 to position the workpiece 200. When the driving rod 21 moves in the chute 111 along the X-axis direction, the supporting member 51 and the positioning needle 52 also move along the X-axis direction along with the driving rod 21, so that the workpiece 200 can be placed on the supporting assembly 10, and after the workpiece 200 is placed, the driving rod 21 moves along the opposite direction of the X-axis, so as to drive the supporting member 51 and the positioning needle 52 to move along the opposite direction of the X-axis, so that the positioning needle 52 can be inserted into the workpiece 200, and further fix the workpiece 200.
In some embodiments, referring to fig. 2 and 4, the positioning plate 12 is further provided with a second avoidance hole 123, where the second avoidance hole 123 corresponds to the positioning needle 52, and is used for the positioning needle 52 to penetrate to avoid the positioning needle 52. Thus, by providing the second avoidance hole 123, the positioning needle 52 can pass through the second avoidance hole 123 to position the workpiece 200, so that the positioning plate 12 is prevented from influencing the use of the positioning needle 52.
In some embodiments, referring to fig. 2, the support assembly 10 further includes a plurality of positioning pins 13, wherein the plurality of positioning pins 13 are connected to a side of the positioning plate 12 facing away from the support assembly 10, and the plurality of positioning pins 13 are configured to be inserted into the workpiece 200 to position the workpiece 200. The positions and the number of the positioning pins 13 can be set according to practical requirements, for example, the positioning pins are arranged around the profiling cavity 121, and when the workpiece 200 is placed in the profiling cavity 121, the positioning pins 13 are inserted into the workpiece 200, so that the purpose of positioning the workpiece 200 on the XY plane is achieved.
The working process of the clamping fixture 100 provided by the embodiment of the utility model is approximately as follows: firstly, pushing force is applied to the driving rod 21 to push the driving rod 21 to slide in the sliding groove 111 along the X-axis direction, the driving rod 21 drives the transmission piece 31 to slide in the first movable groove 112, so that the transmission piece 31 moves away from the driving rod 21, and the transmission piece 31 drives the first abutting piece 32 to slide in the second movable groove 113, so that the first abutting piece 32 moves away from the transmission piece 31; meanwhile, the driving rod 21 drives the second abutting piece 41 to slide in the third movable groove 114, so that the second abutting piece 41 moves away from the driving rod 21; the driving rod 21 also moves the supporting member 51 and the positioning needle 52. Thus, the first abutting piece 32, the second abutting piece 41 and the positioning needle 52 can be controlled to move simultaneously by the driving rod 21. After the driving rod 21 moves along the X axis, one end of the first abutting element 32, the second abutting element 41 and the positioning needle 52, which are used for fixing the workpiece 200, moves away from the profiling cavity 121, at this time, the workpiece 200 can be placed in the profiling cavity 121, and the workpiece 200 is pre-positioned through the profiling cavity 121. Then, the driving rod 21 is released or the driving rod 21 is pulled to move in the opposite direction of the X axis, at this time, the fourth elastic member 22 gives the driving rod 21 elastic force to push the driving rod 21 to move in the opposite direction of the X axis, the third elastic member 42 pushes the second supporting member 41 to move toward the driving rod 21, so that the second supporting member 41 abuts against the workpiece 200, the second elastic member 34 pushes the driving member 31 to move toward the driving rod 21, and the first elastic member 33 pushes the first supporting member 32 to move toward the driving member 31, so that the first supporting member 32 abuts against the workpiece 200. Thus, the workpiece 200 can be positioned from a plurality of directions, and the positioning effect is good.
When the workpiece 200 needs to be disassembled, the operator only needs to push the driving rod 21 again to separate the first abutting piece 32, the second abutting piece 41 and the positioning needle 52 from the workpiece 200, so that the workpiece 200 can be taken out from the profiling cavity 121.
In the clamping jig 100 provided by the embodiment of the utility model, when clamping or disassembling the workpiece 200, an operator only needs to push the driving rod 21 to slide, and the driving rod 21 simultaneously moves the first abutting part 32, the second abutting part 41 and the positioning needle 52 in a direction away from the workpiece 200, so that the workpiece 200 can be easily placed in the profiling cavity 121 or taken out from the profiling cavity 121. Because the auxiliary jig is not required in the process of assembling and disassembling the workpiece 200, the structure of the clamping jig 100 is simplified, and the manufacturing cost of the clamping jig 100 is reduced. In addition, the clamping jig 100 is convenient to assemble and disassemble the workpiece 200, and an operator can easily remove the limitation on the workpiece 200 by pushing the driving rod 21, so that the operation is simple and convenient.
In addition, under the action of the second elastic member 34, the third elastic member 42 and the fourth elastic member 22, the first supporting member 32, the second supporting member 41 and the positioning needle 52 elastically abut against the workpiece 200, so that the first supporting member 32, the second supporting member 41 and the positioning needle 52 are prevented from rigidly contacting the workpiece 200, and the purpose of protecting the workpiece 200 is achieved.
