Auxiliary positioning mechanism and gripping device

Abstract

This application relates to the field of mechanical manufacturing equipment technology, and proposes an auxiliary positioning mechanism and a gripping device. The auxiliary positioning mechanism includes: a base, a first slide rail, and at least one positioning component. The first slide rail includes a first track and a second track. Each positioning component includes a positioning element and a transmission element. The positioning element includes a support element, a second slide rail, at least two first sliding blocks, and a positioning block. The support element is slidably connected to the first slide rail. The second slide rail is mounted on the support element. The first sliding blocks are arranged on the second slide rail. The positioning block is used to connect with a gripper to position the gripper. The transmission element is mounted on the base and connected to the support element. The transmission element is used to drive the support element to move. The gripping device includes: the auxiliary positioning mechanism and at least one gripper. Each gripper is connected to a positioning block.

Claims

2. The auxiliary positioning mechanism as described in claim 1, wherein, The auxiliary positioning mechanism further includes a fastener, which is connected to the first sliding block and is used to fix the relative position of the first sliding block and the second slide rail.

3. The auxiliary positioning mechanism as described in claim 1, wherein, The transmission component further includes: an adjusting screw, a screw sleeve, and fixed seats disposed on both sides of the bearing component. The screw sleeve is threadedly connected to the adjusting screw and fixedly connected to the bearing component. The first end of the adjusting screw is connected to the transmission component, and the second end of the adjusting screw passes through the fixed seat and is rotatably connected to the fixed seat. The transmission component is used to drive the adjusting screw and the screw sleeve to rotate relative to each other, so as to drive the bearing component to move by means of the screw sleeve.

4. The auxiliary positioning mechanism as described in claim 3, wherein, The auxiliary positioning mechanism further includes a fixing plate, which has a first mounting part and a second mounting part. The first mounting part is connected to the carrier, and the second mounting part is connected to the threaded sleeve. The fixing plate is used to fix the relative position between the carrier and the threaded sleeve.

5. The auxiliary positioning mechanism as described in claim 4, wherein, The second mounting part has a first boss and a second boss on the side opposite to one of the bearing members. The opposing sides of the first boss and the second boss are provided with snap-fit ​​grooves. The screw sleeve is provided with a snap-fit ​​part, and the snap-fit ​​part snaps into the snap-fit ​​groove.

6. The auxiliary positioning mechanism as described in claim 1, wherein, The auxiliary positioning mechanism further includes at least two second sliding blocks, wherein the first connecting part is slidably connected to the first track via the second sliding blocks, and the second connecting part is slidably connected to the second track via the second sliding blocks.

7. The auxiliary positioning mechanism as described in claim 1, wherein, The base has a plurality of support members on one side away from the first slide rail. The plurality of support members are arranged around the base to support the base.

8. The auxiliary positioning mechanism as described in claim 7, wherein, The auxiliary positioning mechanism further includes: a plurality of adsorption elements, each of the support members being provided with an adsorption element.

9. A gripping device, improved in that the gripping device comprises: The auxiliary positioning mechanism as described in any one of claims 1 to 8; at least one gripper, each gripper being connected to a positioning block.

10. The gripping device as described in claim 9, wherein, A positioning block is provided with a positioning surface and a positioning part, the positioning part being disposed on the positioning surface. Each gripper includes at least two clamping parts, and there is a positioning space between the opposing surfaces of each clamping part. When each gripper is connected to a positioning block, the positioning part of the positioning block is located within the positioning space to position the relative positions of the clamping parts of each gripper. When the ends of the clamping parts of each gripper abut against the positioning surface, the clamping parts of each gripper can be positioned in a third direction by means of the positioning surface. The first direction and the second direction are both perpendicular to the third direction.
