[0025] A tooling quick-change device comprises a main connection block 1 and a plurality of auxiliary connection blocks 14, wherein the side of the main connection block is respectively provided with a horizontal main connection block positioning guide hole, a main connection block probe mounting hole 26 and a main connection block valve hole 9, and the top of the main connection block is provided with a vertical main connection block communication connector mounting hole and a water inlet or air inlet 2, a guide positioning pin 25 is fixedly installed at the main connection block positioning guide hole, a main connection block probe seat 27 is fixedly installed at the main connection block probe mounting hole, a main connection block probe 28 is fixedly installed on the main connection block probe seat, a plurality of main connection block communication connectors 30 are fixedly installed at the main connection block communication connector mounting hole, a main connection block switching valve is installed at the main connection block valve hole, and the water inlet or air inlet is connected to the main connection The connecting block valve holes are connected, and the side parts of the auxiliary connecting block are respectively provided with a horizontal auxiliary connecting block positioning guide hole, an auxiliary connecting block probe mounting hole 21, and an auxiliary connecting block valve hole 16. The top of the auxiliary connecting block is provided with a vertical auxiliary connecting block communication connector mounting hole and a water outlet or air outlet 13. A positioning guide sleeve 22 is fixedly installed at the auxiliary connecting block positioning guide hole, a auxiliary connecting block probe seat 20 is fixedly installed at the auxiliary connecting block probe mounting hole, and an auxiliary connecting block probe 19 is fixedly installed on the auxiliary connecting block probe seat. A plurality of auxiliary connecting block communication connectors 24 are fixedly installed at the auxiliary connecting block communication connector mounting hole, and an auxiliary connecting block switching valve corresponding to the main connecting block switching valve is installed at the auxiliary connecting block valve hole. The water outlet or air outlet is connected to the auxiliary connecting block valve hole.

[0026] Optimized, the main connection block communication connector mounting hole is connected to the main connection block probe mounting hole, and a main connection block communication connector cover 29 is fixedly installed at the main connection block communication connector mounting hole. A plurality of main connection block communication interfaces are provided on the main connection block communication connector cover, and a main connection block communication connector connected to the main connection block probe is installed at each main connection block communication interface, which can realize stable operation of the main connection block power supply and communication, and each communication interface does not affect each other.

[0027] Optimized, the auxiliary connection block communication connector mounting hole is connected to the auxiliary connection block probe mounting hole, and a auxiliary connection block communication connector cover 23 is fixedly installed at the auxiliary connection block communication connector mounting hole. A plurality of auxiliary connection block communication interfaces are provided on the auxiliary connection block communication connector cover, and each auxiliary connection block communication interface is installed with an auxiliary connection block communication connector connected to the auxiliary connection block probe, which can realize stable operation of the auxiliary connection block power supply and communication, and each communication interface does not affect each other.

[0028] Furthermore, each of the auxiliary connecting block valve holes is a blind hole, and the auxiliary connecting block switching valve is provided with an auxiliary connecting block valve core 10, and an auxiliary connecting block sleeve 12 is clamped on the outer end of the auxiliary connecting block valve hole, and the outer end of the auxiliary connecting block sleeve protrudes from the auxiliary connecting block and the inner hole of the auxiliary connecting block sleeve is a conical structure, and an auxiliary connecting block spring 15 is installed in the auxiliary connecting block valve hole, and the auxiliary connecting block valve core is movably installed in the auxiliary connecting block sleeve and cooperates with the inner hole of the auxiliary connecting block sleeve, and the auxiliary connecting block spring is clamped on the auxiliary connecting block valve core. When the auxiliary connecting block valve core is pushed forward by external pressure, the auxiliary connecting block valve core retracts into the auxiliary connecting block valve hole, so that a passage is formed between the auxiliary connecting block sleeve, the auxiliary connecting block valve hole and the water outlet or air outlet, so that the auxiliary connecting block water path or air path is in a quickly connected state. When the external pressure is withdrawn, the auxiliary connecting block valve core automatically resets under the action of the auxiliary connecting block spring, so that the auxiliary connecting block water path or air path is in a quickly disconnected state.

[0029] Furthermore, each of the main connecting block valve holes is a blind hole, the main connecting block switching valve is provided with a main connecting block valve core 7, the outer end of the main connecting block valve hole is movably installed with a main connecting block sleeve 4, the inner hole of the outer end of the main connecting block sleeve is a bell-mouth shape, the main connecting block valve core is movably installed in the main connecting block sleeve and the bottom is fixedly connected to the main connecting block, a main connecting block spring 8 is installed in the main connecting block valve hole and rests on the end of the main connecting block sleeve, and the outer end of the main connecting block valve core is a bell-mouth shape that matches the inner holes of the main connecting block sleeve and the auxiliary connecting block sleeve.

[0030] When external force pushes the main connecting block to move toward the auxiliary connecting block, the main connecting block sleeve and the auxiliary connecting block sleeve continue to move after contact, and the two are squeezed and fitted to form a good seal. Due to the action of the main connecting block spring, the main connecting block will drive the main connecting block valve core to continue to move forward until the main connecting block is moved against the auxiliary connecting block. At this time, the end of the main connecting block valve core will extend into the auxiliary connecting block sleeve to push the auxiliary connecting block valve core forward, causing the auxiliary connecting block valve core to retract into the auxiliary connecting block valve hole, thereby forming a gas or water path between the water inlet or air inlet, the main connecting block valve hole, the main connecting block sleeve, the auxiliary connecting block sleeve, the auxiliary connecting block valve hole and the water outlet or air outlet, thereby quickly connecting the gas or water path of the workstation and providing an air source or water source for the workstation.

[0031] When processing is completed at that station, the main connection block retreats away from the secondary connection block, and the main connection block valve core withdraws from the secondary connection block sleeve. The main connection block sleeve returns to its original position under the action of the secondary connection block spring's restoring force, forming a seal between the main connection block sleeve and the main connection block valve core, cutting off the air or water path. At this time, the valve core of the secondary connection block sleeve loses the pressure of the main connection block valve core and returns to its original position under the action of the secondary connection block spring's restoring force. The seal between the secondary connection block valve core and the secondary connection block sleeve cuts off the air or water path, thereby achieving rapid switching between water or air paths at multiple stations.

[0032] The secondary connection block valve core is optimally fixed with a flange 18. The outer end of the secondary connection block valve core is tapered to mate with the outer end of the secondary connection block valve hole. This ensures a good seal when the secondary connection block valve core is not connected, and ensures smooth flow of water or gas passages when connected. The flange facilitates installation and sealing.

[0033] Optimized, a sealing groove is provided on the outer end surface of the main connecting block sleeve, and a first seal 5 is installed in the sealing groove, which facilitates the formation of a good seal between the main connecting block sleeve and the auxiliary connecting block sleeve after the water circuit or the gas circuit is connected; a second seal 3 is provided between the main connecting block sleeve and the main connecting block, which facilitates the formation of a good seal between the main connecting block sleeve and the main connecting block; a third seal 6 is provided on the valve core of the main connecting block to prevent gas or water leakage between the valve core of the main connecting block and the main connecting block sleeve when the gas source or water source is not connected.

[0034] Furthermore, a fourth seal 17 is provided between the auxiliary connecting block sleeve and the auxiliary connecting block, which facilitates good sealing between the auxiliary connecting block sleeve and the auxiliary connecting block; a fifth seal 11 is provided at the flange of the auxiliary connecting block valve core to achieve good sealing between the auxiliary connecting block valve core and the auxiliary connecting block sleeve, preventing backflow of air or water when the air source or water source is not connected.

[0035] Furthermore, an additional floating mechanism is installed at the rear of the main connecting block. This mechanism is driven to reciprocate by a pneumatic device. The additional floating mechanism is connected to the main connecting block via a set screw. The main connecting block includes a set screw clearance hole with a set screw compensation space. A buffer adjustment spring, sleeved over the set screw, is installed between the additional floating mechanism and the main connecting block. The pneumatic device drives the additional floating mechanism to reciprocate, thereby driving the reciprocating motion of the main connecting block. The buffer adjustment spring and the set screw compensation space ensure that the main connecting block can achieve floating compensation, preventing the main connecting block's guide positioning pins from becoming stuck or misaligned.

[0036] The present invention protects a tool quick-changing device, in which the auxiliary connection block parts are composed of multiple sets, which are fixedly installed on the corresponding work stations respectively. The main connection block part only requires one set, which can move left and right along the work station. After being aligned with the auxiliary connection block part of the corresponding work station, the main connection block moves toward the auxiliary connection block part, and the guide positioning pin of the main connection block is inserted into the positioning guide hole of the auxiliary connection block of the corresponding work station to realize the precise positioning and guiding of the main connection block. When the guide positioning pin runs to the end of the positioning guide hole, the main connection block probe is just inserted into the auxiliary connection block probe seat to realize the connection of the circuit and supply power to the communication system. In addition, the main connection block switching valve is connected to the auxiliary connection block switching valve to form a water or air source passage, so that the water or air source passes through the main connection block and the auxiliary connection block and is supplied to the corresponding workstation for use until the processing of the workstation is completed. The main connection block retreats under the drive mechanism, and the auxiliary connection block of the workstation is partially powered off, and the water source or air source is in a disconnected state. Then the main connection block is driven by the drive device to run to the auxiliary connection block of the next workstation, and the above actions are repeated to complete the processing of the next workstation.

[0037] Since the present invention is provided with multiple sets of auxiliary connection blocks and one set of main connection blocks, through the movement of the main connection blocks, one set of main connection block systems can be quickly switched between multiple sets of auxiliary connection block systems, thereby realizing rapid switching of circuits, communications, water circuits or gas circuits of multiple workstations. Two sets of main connection block switching valves and auxiliary connection block switching valves can be provided, one set for the gas circuit and the other set for the water circuit. Not only is the structure simple and the floor space occupied small, but the production cost of the enterprise is reduced, the production efficiency is improved, and the system operation is stable and reliable.

[0038] In summary, the present invention provides a tooling quick-change device with a simple structure, low cost, small footprint, and the ability to achieve multi-station communication, power supply, and rapid switching of gas or water sources.
