Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present application provides a pressing claw 100. The press jaw 100 is capable of pushing a workpiece into a mechanism carrying the workpiece during a blanking process. The pressing claw 100 comprises a base 10, a clamping assembly 20 and a pushing assembly 30.

For ease of understanding, a three-dimensional coordinate system is established in FIG. 1, with the directions of the X, Y and Z axes being shown as being perpendicular to each other. Wherein the first direction is defined as the Z-axis direction and the second direction is defined as the X-axis direction.

The clamping assembly 20 is used for clamping the workpiece to transfer the workpiece, and the pushing assembly 30 is used for pushing the workpiece into a mechanism for bearing the workpiece. In the present embodiment, the number of the clamping assemblies 20 and the pushing assemblies 30 is two, the two groups of clamping assemblies 20 are disposed on the base 10 at intervals, and the two groups of pushing assemblies 30 respectively correspond to the two groups of clamping assemblies 20. When two groups of clamping assemblies 20 need to put the workpieces into the mechanism for carrying the workpieces, the clamping assemblies 20 release the workpieces first, and meanwhile the pushing assembly 30 pushes the workpieces to enable the workpieces to accurately fall into the mechanism for carrying the workpieces. Because the pushing component 30 can accurately push the workpiece into the mechanism for bearing the workpiece in the discharging process, the risk of inaccurate falling position caused by the falling position of the workpiece due to self-gravity is avoided.

Referring to fig. 1 and 2, the two sets of clamping assemblies 20 in the present embodiment have the same structure, and one set of clamping assemblies is described below as an example. The clamping assembly 20 includes a clamping drive 21, a buffer unit 22, a first jaw 23a, a second jaw 23b, and a positioning member 24. The clamping driving member 21 may be a clamping jaw cylinder, the clamping driving member 21 is connected to the base 10, and the clamping driving member 21 is connected to the pushing component 30. The first clamping jaw 23a is connected to the pushing assembly 30, the second clamping jaw 23b is connected to the buffer unit 22, and the buffer unit 22 is connected to the clamping driving member 21. A positioning member 24 is attached to the base 10, and the positioning member 24 is spaced apart from the first jaw 23a and the second jaw 23b, for example, the positioning member 24 is located between the first jaw 23a and the second jaw 23 b. When the pressing claw 100 clamps a workpiece, the workpiece is abutted against the positioning member 24 to position the workpiece, and the clamping driving member 21 drives the pushing assembly 30 and the buffer unit 22 to move so as to drive the first clamping jaw 23a and the second clamping jaw 23b to approach each other to accurately clamp the side surface of the workpiece, wherein the second clamping jaw 23b is elastically abutted against the workpiece under the buffering action of the buffer unit 22 when being abutted against the workpiece. Since the second jaw 23b is elastically abutted against the workpiece, the first jaw 23a and the second jaw 23b do not pinch the workpiece when clamping the workpiece.

In the present embodiment, the number of the first clamping jaws 23a is two, the number of the second clamping jaws 23b is one, the second clamping jaw 23b is located between the two first clamping jaws 23a, and the three clamping jaws jointly clamp the workpiece.

Referring to fig. 2 and 3, the buffer unit 22 includes a support 221 and a buffer 222. The support 221 includes a connection block 2211, a connection rod 2212, and a support block 2213. The support block 2213 is connected to the clamping driving piece 21, the connecting block 2211 is connected to the support block 2213, the number of the connecting rods 2212 is two, two connecting rods 2212 are arranged at intervals, and two ends of each connecting rod 2212 are connected with the support block 2213 and the connecting block 2211 respectively. The second clamping jaw 23b is slidably connected to the two connecting rods 2212, the number of the buffer pieces 222 is two, the buffer pieces 222 can be springs, the two buffer pieces 222 are respectively sleeved on the two connecting rods 2212, and two ends of each buffer piece 222 are respectively abutted to the second clamping jaw 23b and the connecting block 2211. When the clamping driving member 21 drives the buffer unit 22 to move towards the workpiece, the second clamping jaw 23b starts to slide along the connecting rod 2212 and compress the buffer member 222 after abutting against the surface of the workpiece, and the second clamping jaw 23b elastically abuts against the workpiece under the action of the buffer member 222 so as to achieve the purpose of preventing clamping damage to the workpiece.

In order to be able to clamp the workpiece more firmly, the first clamping jaw 23a and the second clamping jaw 23b are each provided with anti-slip patterns 231, the anti-slip patterns 231 being formed by grid-shaped grooves. When the anti-skid patterns 231 are abutted against the workpiece, friction between the first clamping jaw 23a and the workpiece and friction between the second clamping jaw 23b and the workpiece can be increased, so that the first clamping jaw 23a and the second clamping jaw 23b clamp the workpiece more firmly.

Referring to fig. 1 and 2, each set of pushing components 30 includes a pushing member 31, an elastic member 32 and a limiting member 33. The number of the pushing pieces 31 is two, and the two pushing pieces 31 are slidably connected to the base 10. The pushing member 31 includes a rod body 311, a stop portion 312, a pushing portion 313 and a ball portion 314, for example, a guide bearing 11 is mounted on the base 10, one end of the rod body 311 is slidably connected to the guide bearing 11 along the Z-axis direction, the other end of the rod body 311 penetrates through the limiting member 33 and the positioning member 24, the ball portion 314 is connected to one end of the rod body 311 away from the guide bearing 11, and the ball portion 314 is used for pushing a workpiece so as to push the workpiece into a mechanism for carrying the workpiece. Because the ball head 314 is in point contact with the workpiece, the contact area between the ball head 314 and the workpiece is small, so that the pushing piece 31 is not easy to scratch the workpiece in the process of pushing the workpiece, and the workpiece is protected.

The stop portion 312 is connected to a side surface of the rod 311, and a diameter of the stop portion 312 is larger than a diameter of the rod 311. The number of the elastic members 32 is two, the two elastic members 32 are respectively sleeved on the two rod bodies 311, and two ends of the elastic members 32 are respectively abutted against the stop portion 312 and the base 10. The rod 311 can slide relative to the base 10 under the action of the elastic member 32 to drive the ball portion 314 to push the workpiece.

The limiting member 33 is connected to the clamping driving member 21, the two first clamping jaws 23a are connected to the limiting member 33, and the two first clamping jaws 23a are connected to the clamping driving member 21 through the limiting member 33. The limiting member 33 is provided with two protruding inclined surface portions 331, in this embodiment, the inclined surface portions 331 are provided with a yielding hole 332, and the yielding hole 332 is elongated and is disposed along the X-axis direction. The portions of the two rod bodies 311 located at the lower sides of the stop portions 312 respectively penetrate through the yielding holes 332 on the two inclined surface portions 331 and penetrate through the positioning piece 24 located below the inclined surface portions 331, when the limiting piece 33 moves under the driving of the clamping driving piece 21, the rod bodies 311 slide in the yielding holes 332 along the X-axis direction relative to the limiting piece 33, and can relatively move to the lower end or the higher end of the yielding hole 332. The supporting portion 313 is connected to a side of the stopping portion 312 facing the limiting member 33, and an end of the supporting portion 313 facing the limiting member 33 is a cambered surface. When the clamping assembly 20 does not clamp the workpiece, the abutting part 313 on the abutting part 31 abuts against the limiting part 33 under the action of the elastic part 32; when the clamping assembly 20 starts to clamp the workpiece, the limiting member 33 is driven by the clamping driving member 21 to move along the X-axis direction, at this time, the abutting portion 313 slides along the inclined direction of the inclined surface portion 331 from the bottom of the inclined surface portion 331 to the top of the inclined surface portion 331, and at the same time, the rod body 311 slides along the X-axis direction from the lower end to the higher end of the relief hole 332; when the rod 311 moves along the X-axis, the inclined surface 331 pushes the abutting portion 313, so that the abutting portion 313 slides along the rod 311 along the Z-axis direction relative to the base 10, and the stopper 312 compresses the elastic member 32. The pushing member 31 can avoid the workpiece when the clamping assembly 20 clamps the workpiece due to the action of the limiting member 33. Meanwhile, the limiting member 33 enables the pushing member 31 to compress the elastic member 32 to accumulate power, so that the pushing member 31 can push the workpiece into the mechanism for carrying the workpiece when the clamping assembly 20 releases the workpiece. Due to the existence of the relief hole 332, the rod body 311 moves relative to the relief hole 332 when the limiting member 33 moves, so that the abutting portion 313 abuts against different height positions of the inclined surface portion 331.

The nip finger 100 also includes a sensing member 40 and a sensor 50. The sensing element 40 is integrally formed on the second jaw 23 b. The sensor 50 may be a proximity switch, the sensor 50 being coupled to the base 10, the sensor 50 sensing the presence of the workpiece on the clamping assembly 20 by sensing the sensing member 40. When the clamping assembly 20 takes a material, for example, when the clamping assembly 20 does not clamp a workpiece, the second clamping jaw 23b moves with the sensor member 40 to a range sensed by the sensor 50, and at this time, when the sensor 50 senses the sensor member 40, an operator can know that the clamping assembly 20 does not clamp the workpiece. When the clamping assembly 20 clamps the workpiece, the sensing element 40 is located outside the sensing range of the sensor 50, and the operator can know that the clamping assembly 20 clamps the workpiece because the sensor 50 does not sense the sensing element 40.

The press jaw 100 further includes a sensor 60, the sensor 60 being configured to sense a mechanism carrying a workpiece. When the workpiece is clamped by the pressing claw 100, the external mechanism for carrying the workpiece moves to the pressing claw 100, or the pressing claw 100 moves to the mechanism for carrying the workpiece, and when the sensor 60 senses the mechanism for carrying the workpiece, the alignment of the pressing claw 100 and the mechanism for carrying the workpiece is described, and at this time, the pressing claw 100 can press the workpiece into the mechanism for carrying the workpiece.

The working process of the pressing claw 100 provided in the embodiment of the present application is approximately:

first, the workpiece is clamped by the pressing claw 100, for example, the pressing claw 100 can be moved to the upper side of the workpiece by an external driving mechanism, and then, the pressing claw 100 descends and makes the positioning member 24 abut against the workpiece, and the clamping assembly 20 can accurately clamp the workpiece under the positioning action of the positioning member 24. Then, the clamping driving member 21 moves by driving the supporting member 221 and the limiting member 33 to drive the first clamping jaw 23a and the second clamping jaw 23b to approach each other along the X-axis direction; the first clamping jaw 23a directly abuts against the workpiece, and the second clamping jaw 23b slides along the connecting rod 2212 and compresses the buffer member 222 when abutting against the workpiece, at this time, the second clamping jaw 23b elastically abuts against the workpiece under the action of the buffer member 222. While the clamping assembly 20 clamps the workpiece, the limiting member 33 moves along with the clamping driving member 21, at this time, the rod 311 slides from the lower end to the higher end of the yielding hole 332 along the X-axis direction, the abutting portion 313 on the rod 311 slides from the bottom end to the top end of the inclined surface 331, and under the action of the inclined surface 331, the abutting portion 313 slides along the Z-axis direction with the rod 311 relative to the base 10, and the stop portion 312 compresses the elastic member 32.

When the material pressing paw 100 needs to discharge, the clamping driving member 21 drives the first clamping jaw 23a and the second clamping jaw 23b to loosen the workpiece, at this time, the rod body 311 slides from the higher end to the lower end of the yielding hole 332 along the X-axis direction, the abutting portion 313 on the rod body 311 slides from the top end to the bottom end of the inclined surface portion 331, and meanwhile, the elastic member 32 resets and pushes the stop portion 312 to enable the rod body 311 to drive the ball portion 314 to push the workpiece in the Z-axis direction, so as to push the workpiece into the mechanism for bearing the workpiece.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
