Positioning device

Abstract

This application discloses a positioning device, including a platform, a pressing cylinder, a first pressing member, and a translation module. The platform is used to support the product. The pressing cylinder is located above the platform and is connected to both the first pressing member and the translation module. The pressing cylinder is equipped with a pressure relief valve. When tightening screws at different positions on the part, the translation module drives the first pressing member to move, allowing it to adapt to different positions on the part and thus improving the accuracy of pressing the part. Simultaneously, when the first pressing member moves relative to the part, the pressure relief valve releases pressure from the pressing cylinder, removing the pressure applied by the first pressing member to the part and reducing the risk of the first pressing member scratching the part.

Claims

1. A positioning device for positioning the relative positions of a product and a part, the improvement of which comprises: A platform for supporting the product; A pressing cylinder and a first pressing component are provided. The pressing cylinder is located above the platform and connected to the first pressing component, which drives the first pressing component to move up and down relative to the platform. The first pressing component is used to press the part towards the product. The first pressing component has two clearance holes for accommodating screws and screwdriver bits, allowing the screwdriver bits to lock the part and the product together. A translation module is connected to the pressing cylinder and is used to drive the pressing cylinder to translate relative to the platform, thereby moving the first pressing component. The pressing cylinder is equipped with a pressure relief valve. When the translation module drives the pressing cylinder to move, the pressure relief valve is used to relieve pressure on the pressing cylinder to remove the force applied by the pressing cylinder to the first pressing component.

2. The positioning device as described in claim 1, wherein, The positioning device further includes a first flap, which is rotatably connected to the platform, and the translation module is connected to the first flap; the first flap is used to drive the translation module to rotate relative to the platform, and simultaneously drive the pressing cylinder and the first pressing component to rotate.

3. The positioning device as described in claim 2, wherein, The first flap has a closed state and an open state. When the first flap is in the closed state, the pressing surface of the first pressing member faces downward. When the first flap is in the open state, the pressing surface of the first pressing member faces upward. The first pressing member is used to support the part when the first flap is in the open state. The pressing surface of the first pressing member is provided with an adsorption hole, which is used to adsorb the part.

4. The positioning device as described in claim 2, wherein, The translation module includes a first cylinder, a first slide rail, and a first mounting plate. The first slide rail and the first cylinder are respectively disposed on the first flip plate. The first mounting plate is connected to the first slide rail, and the pressing cylinder is connected to the first cylinder. The first cylinder is used to drive the first mounting plate to slide on the first slide rail and simultaneously drive the pressing cylinder to move horizontally relative to the platform to adjust the position of the first pressing component.

5. The positioning device as described in claim 4, wherein, The positioning device further includes a second mounting plate, which is connected to the first mounting plate and the pressing cylinder respectively. The second mounting plate is provided with a second slide rail, and the first pressing member is slidably connected to the second slide rail. The second slide rail is used to guide the first pressing member to move up and down.

6. The positioning device as described in claim 5, wherein, The pressing cylinder is connected to the first pressing member via a connecting block. A reset member is provided between the connecting block and the second mounting plate. One end of the reset member is connected to the connecting block, and the other end is in contact with the second mounting plate.

7. The positioning device as described in claim 5 or 6, wherein, The first mounting plate is provided with a limiting block, a portion of which extends above the downward pressing cylinder. The limiting block is used to limit the upward stroke of the downward pressing cylinder. Alternatively, the downward pressing cylinder is connected to the first pressing member via a connecting block. The connecting block is provided with a limiting bolt, which is movably connected to the connecting block via threads. A portion of the limiting bolt protrudes downward from the connecting block and is used to contact the first mounting plate or the second mounting plate to limit the downward stroke of the connecting block.

8. The positioning device as described in claim 4, wherein, The first flap is provided with a front limiter and a rear limiter, which are spaced apart along the moving direction of the translation module; the translation module also includes a baffle disposed between the front limiter and the rear limiter, the baffle being connected to the telescopic end of the first cylinder, and the front limiter and the rear limiter being used to limit the movement of the baffle.

9. The positioning device as described in claim 2, wherein, The positioning device further includes a blocking assembly, which includes a second cylinder and a blocking member. The second cylinder is connected to the first flap and the blocking member respectively. A portion of the blocking member extends above one of the clearance holes of the first pressing member, and the blocking member is used to cover the clearance hole. The second cylinder is used to drive the blocking member to move relative to the platform so that the blocking member and the first pressing member remain relatively stationary.

10. The positioning device as described in claim 2, wherein, The positioning device further includes a second flip plate and a third flip plate, which are rotatably connected to the platform. The second flip plate is provided with a second pressing member, and the third flip plate is provided with a third pressing member. The second pressing member and the third pressing member are respectively located on both sides of the first pressing member. The second pressing member and the third pressing member can act on the wiring of the part and position the wiring.
