In many cases, the gripper device is installed on a robot or AGV, and the robot or AGV is used to automatically grip and transport the product. For example, in the Chinese invention patent application with application number 202111565726.6, application publication date February 11, 2022, and invention name "A gripper device and an industrial robot having the gripper device", the gripper device disclosed therein includes: two synchronous pulleys and a synchronous belt wound around the two synchronous pulleys; a first gripper and a second gripper arranged opposite to each other, and the two are respectively connected to the synchronous belt on different sides of the synchronous pulley; a telescopic assembly connected between the first gripper and the second gripper, which has an extended state and a retracted state. When the telescopic assembly is in the extended state, the first gripper and the second gripper release the workpiece; when the telescopic assembly is in the retracted state, the first gripper and the second gripper clamp the workpiece. Since the first clamping jaw and the second clamping jaw are both strip-shaped and both clamping jaws are vertically connected to the synchronous belt, the first clamping jaw and the second clamping jaw move parallel to each other when clamping or releasing the workpiece, which results in a larger volume of the entire clamping jaw device.

[0007] The present invention discloses an adaptive spacing adjustable clamping jaw device, wherein the clamping arm body is rotatably mounted on the clamping frame in the following specific manner: a sleeve is fixedly provided at one end of the clamping arm body, a vertical shaft used in conjunction with the sleeve is fixedly provided on the clamping frame, and the sleeve is rotatably mounted on the vertical shaft via a bearing.

[0008] The present invention provides an adaptive spacing adjustable clamping jaw device, wherein the two limiting structures are two limiting plates, both of which are fixed on the clamping frame, and both of which are located between two clamping arm bodies, and each of the limiting plates is arranged corresponding to the clamping arm body it is close to.

[0036] like Figure 1 As shown, combined with Figure 2-20 As shown, the adaptive spacing adjustable clamping jaw device of the present invention includes a clamping frame 20, on which two clamping arms 39 are rotatably mounted. The clamping frame 20 is also provided with a clamping arm driver connected to the two clamping arms 39, and the clamping arm driver can drive the two clamping arms 39 to rotate closer to or away from each other.

[0037] The clamping frame 20 in this embodiment is in the shape of a rectangular parallelepiped, and the two clamping arms 39 are rotatably installed in the middle position on one side of the length direction of the clamping frame 20. When the clamping arm driver drives the two clamping arms 39 to rotate away from each other, the two clamping arms 39 move closer to the two ends of the clamping frame 20 respectively until the two clamping arms 39 are basically arranged parallel to the clamping frame 20, which can minimize the volume of the entire adaptive spacing adjustable clamping jaw device; when the clamping arm driver drives the two clamping arms 39 to rotate closer to each other, the two clamping arms 39 move away from the two ends of the clamping frame 20 respectively until the two clamping arms 39 are perpendicular to the clamping frame 20 (at this time, the two clamping arms 39 are parallel to each other), and at this time, the two clamping arms 39 are in a clamping state and can clamp the product 4 located between the two clamping arms 39.

[0038] like Figure 2 , 10 As shown, the clamping arm driver includes a clamping motor 45 and a forward and reverse rotating screw 54, and the forward and reverse rotating screw 54 is rotatably mounted on the clamping frame 20, and the clamping motor 45 is mounted on the clamping frame 20 and connected to the forward and reverse rotating screw 54, and two nuts 50 are threadedly connected to the forward and reverse rotating screw 54, and the two nuts 50 are respectively connected to the forward and reverse threads of the forward and reverse rotating screw 54.

[0039] The two nuts 50 are arranged in one-to-one correspondence with the two sliders 55, and the nuts 50 are fixedly connected to the corresponding sliders 55. The two sliders 55 are both slidably installed on the clamping frame 20. Specifically, a slide rail 53 is fixedly provided on the clamping frame 20, and the slide rail 53 is arranged along the length direction of the clamping frame 20. The two sliders 55 are both slidably installed on the slide rail 53.

[0040] Since the two nuts 50 are fixedly connected to the two sliders 55 respectively, and the sliders 55 are slidably installed on the clamping frame 20, when the clamping motor 45 drives the forward and reverse rotation screw 54 to rotate, the two nuts 50 drive the two sliders 55 to slide closer to or away from each other along the clamping frame 20, and the two sliders 55 are arranged one by one with the two clamping arms 39. A connecting rod 46 is hinged between the slider 55 and the corresponding clamping arm 39, that is, one end of the connecting rod 46 is hinged to the slider 55, and the other end of the connecting rod 46 is hinged to the clamping arm 39 corresponding to the slider 55.

[0041] When the two sliders 55 slide toward each other along the clamping frame 20, the two sliders 55 push the two clamping arms 39 to rotate toward each other through the two connecting rods 46, that is, the two clamping arms 39 are used to clamp the product 4; when the two sliders 55 slide away from each other along the clamping frame 20, the two sliders 55 pull the two clamping arms 39 to rotate away from each other through the two connecting rods 46, that is, the two clamping arms 39 are used to release the product 4.

[0042] Combination Figure 3-9 As shown, the clamping arm 39 includes a clamping arm body 40 and an extension arm 48, the clamping arm body 40 is rotatably mounted on the clamping frame 20, the extension arm 48 is arranged side by side with the clamping arm body 40, the extension arm 48 is slidably connected to the clamping arm body 40, an elastic member is provided between the extension arm 48 and the clamping arm body 40, the connecting rod 46 is hinged between the slider 55 and the corresponding extension arm 48 of the clamping arm 39, and two limiting structures are provided on the clamping frame 20, the two limiting structures are arranged one by one with the two clamping arm bodies 40, when the two clamping arm bodies 40 rotate close to each other, they can resist against their respective corresponding limiting structures and no longer continue to rotate, when the two clamping arm bodies 40 resist against their respective corresponding limiting structures, the extension arm 48 can slide away from the clamping arm body 40 under the push of the connecting rod 46 and cause the elastic member to deform.

[0043] The specific way in which the clamping arm body 40 is rotatably mounted on the clamping frame 20 is as follows: a sleeve 38 is fixedly disposed at one end of the clamping arm body 40, a vertical shaft 35 used in conjunction with the sleeve 38 is fixedly disposed on the clamping frame 20, and the sleeve 38 is rotatably mounted on the vertical shaft 35 via a bearing. In this way, the clamping arm body 40 can rotate around the vertical shaft 35 in the horizontal direction.

[0044] The two clamping arm bodies 40 can rotate around their respective vertical axes 35 in the horizontal direction to move closer to or farther from each other. During this process, the two extension arms 48 rotate along with the two clamping arm bodies 40 to move closer to or farther from each other.

[0045] The present invention discloses an adaptive spacing adjustable clamping jaw device, wherein a guide column 49 is slidably inserted into the clamping arm body 40, and both ends of the guide column 49 are respectively located on opposite sides of the clamping arm body 40, one end of the guide column 49 is fixedly connected to an extension arm 48, and an elastic member is provided between the other end of the guide column 49 and the clamping arm body 40, and the extension arm 48 can slide away from the clamping arm body 40 under the push of a connecting rod 46 and cause the elastic member to produce compression deformation.

[0046] In this embodiment, four guide posts 49 are provided on each clamping arm body 40, and the four guide posts 49 form two guide post groups, and each guide post group includes two guide posts 49. A baffle 51 is fixedly connected between the other ends of the two guide posts 49 of each guide post group, and the baffle 51 is located between the clamping arm body 40 and the slide rail 53, and the baffle 51 and the extension arm 48 are respectively located on opposite sides of the clamping arm body 40. It can be said that the baffle 51 is located on the side of the clamping arm body 40 close to the slide rail 53, and the extension arm 48 is located on the side of the clamping arm body 40 away from the slide rail 53. An elastic member is provided between the baffle 51 and the clamping arm body 40, and the elastic member is a gas spring 52, one end of the gas spring 52 (the piston rod of the gas spring 52 in this embodiment) is fixedly connected to the baffle 51, and the other end of the gas spring 52 (the piston cylinder of the gas spring 52 in this embodiment) is fixedly connected to the clamping arm body 40. It can be seen that the extension arm 48 is slidably connected to the clamping arm body 40 through the guide column 49. When the connecting rod 46 pushes the extension arm 48 to slide away from the clamping arm body 40, the baffle 51 compresses the gas spring 52 and causes it to undergo compression deformation (i.e., the piston rod of the gas spring 52 contracts into the piston cylinder); thereafter, when the connecting rod 46 no longer pushes the extension arm 48, i.e., the baffle 51 no longer compresses the gas spring 52, the gas spring 52 returns to its extended state. During this process, under the push of the gas spring 52, the extension arm 48 slides close to the clamping arm body 40 until the two are against each other.

[0047] The gas spring 52 is a prior art, and its specific structure and working principle are not described here. In addition to the gas spring 52, the elastic member can also use an ordinary coil spring, that is, one end of the coil spring is fixedly connected to the baffle 51, and the other end of the coil spring is fixedly connected to the clamping arm body 40.

[0048] The two limiting structures are two limiting plates 47, both of which are fixed on the clamping frame 20, and both of which are located between the two clamping arms 39 / clamping arm bodies 40. Each limiting plate 47 is arranged corresponding to the clamping arm 39 / clamping arm body 40 to which it is close, that is, each limiting plate 47 forms a corresponding arrangement relationship with the clamping arm 39 / clamping arm body 40 to which it is close.

[0049] In the initial state, Fig.11 , 12 As shown, when the clamping arm 39 has not clamped the product 4, the elastic member is in the extended state, and under the action of the elastic member, the extension arm 48 is pressed against the clamping arm body 40. When the clamping motor 45 drives the forward and reverse screw 54 to rotate forward, the two sliders 55 slide toward each other along the clamping frame 20, and then the two sliders 55 push the two clamping arms 39 to rotate toward each other through the two connecting rods 46. In this process, the extension arm 48 and the clamping arm body 40 are pressed against each other under the action of the elastic member in the extended state, and the force of the connecting rod 46 pushing the extension arm 48 cannot cause the elastic member to produce compression deformation. Therefore, although the connecting rod 46 pushes the extension arm 48, it can also cause the entire clamping arm 39 to rotate, as shown in FIG. Fig.13 , 14 As the two clamping arms 39 continue to rotate, until the two clamping arm bodies 40 respectively abut against the corresponding limit plates 47, the two clamping arm bodies 40 no longer rotate towards each other, and at this time the two clamping arm bodies 40 are parallel to each other, that is, at this time the two clamping arms 39 are in a state of clamping the product 4, as shown in FIG. Fig.15 , 16 If the two clamping arms 39 can just clamp the product 4 at this time, the clamping motor 45 is turned off; if the distance between the two clamping arms 39 is larger than the outer dimensions of the product 4 at this time, the clamping motor 45 needs to continue to drive the forward and reverse screws 54 to rotate, so that the two sliders 55 continue to slide closer to each other along the clamping frame 20, so that the force of the connecting rod 46 pushing the extension arm 48 becomes larger and the elastic member can produce compression deformation, so that the extension arm 48 slides away from the clamping arm body 40, that is, the extension arm 48 moves toward the product 4 (the distance between the two extension arms 48 becomes smaller), until the two extension arms 48 clamp the product 4, as shown in FIG. Figure 17-20 As shown. It can be seen that the purpose of providing the extension arm 48 is to be able to adjust the distance between the two clamping arms 39 so as to adapt to products 4 of different external dimensions.

[0050] When the product 4 needs to be released, the clamping motor 45 drives the forward and reverse screws 54 to rotate in the opposite direction, and the two sliders 55 slide away from each other along the clamping frame 20, so that the force of the connecting rod 46 pushing the extension arm 48 disappears, and the compressed elastic member returns to the extended state, so that the extension arm 48 slides close to the clamping arm body 40 until the two are against each other, at which time the extension arm 48 is out of contact with the product 4. Afterwards, as the two sliders 55 continue to slide away from each other along the clamping frame 20, the two sliders 55 pull the two clamping arms 39 to rotate away from each other through the two connecting rods 46, so that the distance between the two clamping arms 39 increases, and the product 4 is released.

[0051] The adaptive spacing adjustable clamping jaw device of the present invention, wherein the clamping frame 20 is also provided with an electric push rod 26 and a single-line laser radar 28, the electric push rod 26 and the single-line laser radar 28 are both arranged between two clamping arms 39, the electric push rod 26 is located above the two clamping arms 39, and the single-line laser radar 28 is located below the electric push rod 26 and is located in the same horizontal plane as the two clamping arms 39.

[0052] When the two clamping arms 39 clamp the product, the electric push rod 26 can be extended to press against the side of the product 4, so that the side of the product 4 can be supported. Then, the electric push rod 26 and the two clamping arms 39 cooperate with each other to clamp the product 4 firmly.

[0053] The single-line laser radar 28 is used to identify the product 4 to enhance the automatic performance of the entire adaptive spacing adjustable gripper device.

[0054] The electric push rod 26 and the single-line laser radar 28 are both existing technologies, and their specific structures and working principles are not described in detail here.
