Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, for the utility model discloses a steel sheet snatchs gripper, including two body of rods 1 of welded fastening together and install in a plurality of vacuum chuck 2 of two body of rods 1 length direction both ends department. The two rod bodies 1 are crossed and the axes of the two rod bodies 1 are vertically arranged, so that the two rod bodies 1 form a cross-shaped structure. When installing vacuum chuck 2 on the body of rod 1, the terminal surface of the absorption end of vacuum chuck 2 all is located the coplanar.
Referring to fig. 2 and 3, the rod body 1 includes a body section 11 located in the middle and extension sections 12 located at two ends of the body section 11 in the length direction, and the axes of the extension sections 12 and the axis of the body section 11 are located on the same straight line. The body sections 11 of the two rods 1 are fixed together. A bidirectional screw 13 is arranged between the extension section 12 and the body section 11, and the left-hand thread section and the right-hand thread end of the bidirectional screw 13 are respectively in threaded connection with the body section 11 and the extension section 12. An operation part 131 integrally formed with the bidirectional screw 13 is provided between the left-handed thread section and the right-handed thread section of the bidirectional screw 13, and the diameter of the operation part 131 is larger than that of the bidirectional screw 13. The external surface of the operation part 131 is provided with a plurality of ribs 1311 integrally formed with the operation part 131, and the ribs 1311 are uniformly arranged along the circumferential direction of the operation part 131. By holding the operation part 131 by hand, the bidirectional screw 13 is easily rotated, thereby controlling the body section 11 and the extension section 12 to approach or separate from each other.
A guide rod 14 is further arranged between the body section 11 and the extension section 12, one end of the guide rod 14 is fixedly connected with the body section 11 through a connecting sheet 141, and the other end of the guide rod 14 is connected with the extension section 12 in a sliding manner. The guide bar 14 is spaced apart from the operating portion 131 of the bidirectional screw 13, and the operator can hold the operating portion 131 to rotate the bidirectional screw 13. The guide rod 14 is fixedly connected with the connecting piece 141 by welding, and the connecting piece 141 is attached to one end surface of the body section 11 facing the extension section 12 and fixed on the body section 11 by bolts.
Referring to fig. 4, a guide hole 121 is opened at a position opposite to the guide rod 14 at an end of the extension 12 facing the body segment 11, and the guide hole 121 has a diameter such that the guide rod 14 is inserted into the guide hole 121 and slides inside the guide hole 121. The length of the guide bar 14 is shorter than that of the bidirectional screw 13. The end of the guide rod 14 extending into the guide hole 121 is provided with an external flange 142 extending outwards and integrally formed with the guide rod 14, and the diameter of the external flange 142 matches the diameter of the guide hole 121. At one end of the guide hole 121 close to the body section 11, the hole wall of the guide hole 121 is provided with an inner flange 1211 integrally formed with the extension section 12, and the inner diameter of the inner flange 1211 matches with the diameter of the guide rod 14.
The end of the guide bar 14 extending into the guide hole 121 cannot be removed from the guide hole 121 by the engagement of the inner flange 1211 and the outer flange 142. And since the length of the guide rod 14 is shorter than that of the bidirectional screw 13, the bidirectional screw 13 is still in a state of connecting the body section 11 and the extension section 12 when the inner flange 1211 abuts against the outer flange 142.
Referring to fig. 2, the vacuum chuck 2 is mounted on an extension 12 of the rod body 1 by means of a slider 3. The slider 3 comprises a rectangular block 31. The block 31 is provided with a slide hole 32 penetrating the block 31, and the slide hole 32 has a diameter such that the extension 12 can slide relative to the block 31 while penetrating the slide hole 32. The vacuum chuck 2 is fixed to the outer side wall of the block 31. A screw hole communicating with the slide hole 32 is formed in the surface of the block 31, a jack screw 33 is screwed into the screw hole, and when the block 31 is attached to the extension section 12, the jack screw 33 is rotated to move the jack screw 33 in the direction of the slide hole 32, and the jack screw 33 is pressed against the extension section 12, thereby fixing the position of the block 31.
A plurality of fastening holes 122 are opened along the axial direction of the extension section 12. The jack screw 33 is opposed to the chucking hole 122 when the block 31 is mounted on the extension 12. The diameter of the chucking hole 122 is matched with the large diameter of the jack screw 33 so that the jack screw 33 can be inserted into the chucking hole 122. Through stretching into the jackscrew 33 in the card hole 122 to can guarantee that the vacuum chuck 2 on the block 31 when adsorbing the steel sheet, the gliding condition can not appear on extension 12 to block 31 because of the weight of steel sheet.
In order to facilitate the jackscrew 33 to be opposite to the clamping hole 122, a clamping strip 123 integrally formed with the extension section 12 is provided on the surface of the extension section 12, and the length direction of the clamping strip 123 is arranged along the axial direction of the extension section 12. A sliding groove 311 for the card strip 123 to pass through is formed in the block body 31 at a position opposite to the card strip 123, the sliding groove 311 is communicated with the sliding hole 32, and the sliding groove 311 is connected with the card strip 123 in a sliding manner. Through the clamping strip 123 and the sliding groove 311, the jackscrew 33 is always opposite to the clamping hole 122 formed on the extension section 12 when the sliding block 3 moves.
The implementation principle of the embodiment is as follows: when adopting the steel sheet to snatch the gripper and snatch the steel sheet of different specifications, rotate two-way screw 13 through handheld operation portion 131 who rotates two-way screw 13 to adjust the interval between extension section 12 and the body section 11, make its and the steel sheet specification phase-match that will snatch, thereby when vacuum chuck 2 absorbs the steel sheet, make the adsorption affinity that the steel sheet received more even, thereby make the steel sheet difficult to break away from with vacuum chuck.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
