Description

Technical Field

[0001] The utility model relates to the technical field of processing fixtures, in particular to fully automatic assembly equipment for cooling piston nozzle valves. Background Art

[0002] The cooling piston nozzle is a device used to cool the fixture during the fixture clamping process. It usually consists of one or more cooling nozzles, which can reduce the temperature of the fixture by spraying cooling media, such as cold water or coolant. The fully automatic assembly equipment for cooling piston nozzle valves is a highly automated assembly equipment specially used for the production of cooling piston nozzle valves. The equipment adopts advanced automation technology and can realize the fully automatic assembly process from parts to finished products. This equipment usually consists of a conveying system, a detection system, an assembly station and a control system. The conveying system transports parts from the parts storage area to the assembly station, and the detection system performs quality inspection on the parts to ensure the accuracy and quality of the assembly. The assembly station is used to assemble the parts into cooling piston nozzle valves, which includes automated assembly robotic arms, fixing fixtures and bolt tightening devices. The control system is used to control and monitor the assembly process to ensure the smooth progress of the assembly. During the fully automatic assembly process, the equipment will automatically perform the matching, assembly and tightening of parts according to the preset program. It can automatically complete the positioning, alignment, connection and fixing of parts to ensure the accuracy and reliability of the assembly.

[0003] In the clamping process of the existing fully automatic assembly equipment for cooling piston nozzle valves, if the traditional fixture is used to clamp the cooling piston nozzle valve, there will be some disadvantages. First, the operator needs to manually adjust the fixture to adapt to cooling piston nozzle valves of different models and specifications. This process is cumbersome and time-consuming, and requires the operator to have certain experience and skills. Traditional fixtures can usually only adapt to specific models and specifications, and cannot flexibly adapt to the fixing and clamping requirements of parts of different sizes or shapes. This limits the flexibility of clamping and makes it difficult to adapt to product changes or the assembly requirements of new products. When clamping the cooling piston nozzle valve, the traditional fixture may have problems such as uneven clamping force or excessive clamping force, which affects the accuracy and quality of assembly. In addition, since the fixture needs to be manually adjusted and operated, the clamping process is cumbersome and time-consuming, which may reduce production efficiency and increase production costs. After repeated clamping for a long time, the fixture will heat up, affecting the assembly effect. These problems have caused traditional fixtures to be unsuitable in the fully automatic assembly environment, resulting in low production efficiency. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides fully automatic assembly equipment for cooling piston nozzle valves, which has the advantages of no need for additional manual adjustment when clamping cooling piston nozzle valves of different models, and can clamp cooling piston nozzle valves of different sizes and shapes, and can ensure uniform clamping force during the clamping process, and will not generate heat after long-term repeated clamping. It solves the problem that traditional clamps need to be manually adjusted to adapt to cooling piston nozzle valves of different models and specifications, and usually can only adapt to cooling piston nozzle valves of specific models and specifications, and may not be able to effectively fix and clamp parts of different sizes or shapes. When clamping the cooling piston nozzle valve, there may be uneven clamping force or excessive clamping force. The clamp will generate heat after long-term repeated clamping, resulting in low assembly accuracy.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose of clamping different types of cooling piston nozzle valves without additional manual adjustment, and being able to clamp cooling piston nozzle valves of different sizes and shapes, ensuring uniform clamping force during the clamping process, and not generating heat during long-term repeated clamping, the utility model provides the following technical solutions: fully automatic assembly equipment for cooling piston nozzle valves, including a clamp shell and a fixed disk, the fixed disk is fixedly installed on the end face of the clamp shell, an air pipe is arranged in the fixed disk, the air pipe is connected to a pneumatic module, a through hole with a diameter larger than the diameter of the cooling piston nozzle valve angle head is opened in the center of the clamp shell, an air bag is coaxially fixedly installed in the through hole, the air bag is in the shape of a ring, the inner diameter of the air bag in an uninflated state is larger than the diameter of the cooling piston nozzle valve angle head, the air pipe is connected to the interior of the air bag, and the air bag wraps the cooling piston nozzle valve angle head when in an inflated state.

[0008] Preferably, the inner ring surface of the airbag is provided with an anti-slip surface, and the anti-slip surface is made of rubber material.

[0009] Preferably, a circular ring-shaped counterweight ring is fixedly mounted on the bottom end surface of the clamp shell, the inner diameter of the counterweight ring is smaller than the inner diameter of the clamp shell, the inner diameter of the airbag when not inflated is equal to the size of the counterweight ring, and the bottom end surface of the airbag is fixedly mounted on the top of the counterweight ring.

[0010] Preferably, the top end surface of the airbag is fixedly connected to the fixing plate.

[0011] Preferably, an air pressure monitoring module is also provided inside the airbag.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a fully automatic assembly device for cooling piston nozzle valve, which has the following beneficial effects:

[0014] 1. The fully automatic assembly equipment for the cooling piston nozzle valve uses an airbag structure, an air pipe structure, an anti-slip surface, and a fixture shell structure. Compared with the traditional technical structure, in the process of clamping the cooling piston nozzle valve angle head with the fixture, this structure only needs to inflate the airbag to complete precise clamping. There is no need to manually replace or adjust the fixture, and the cooling piston nozzle valve angle heads of different sizes and shapes can be clamped. It has high flexibility, simplifies the clamping steps, and improves production efficiency. In the clamping process, the clamping force is uniform, and will not affect the assembly effect and performance of the cooling piston nozzle valve.

[0015] 2. The fully automatic assembly equipment for the cooling piston nozzle valve uses an airbag structure in conjunction with a fixture shell structure. Compared with the traditional technical structure, this structure replaces and flows the gas inside the airbag during repeated clamping of multiple cooling piston nozzle valve angle heads. Therefore, during repeated clamping, the heat generated by clamping can be taken away by the gas, thereby avoiding the problem of low assembly accuracy caused by heating of the fixture after long-term repeated clamping.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , the fully automatic assembly equipment for the cooling piston nozzle valve includes a fixture shell 1 and a fixed disk 2. The fixed disk 2 is fixedly installed on the end face of the fixture shell 1 shown. An air pipe 3 is arranged in the fixed disk 2. The air pipe 3 is connected to a pneumatic module. A through hole with a diameter larger than the diameter of the air-cooling piston nozzle valve angle head 8 is opened in the center of the fixture shell 1. An air bag 4 is coaxially fixedly installed in the through hole. The reason why this installation ensures that the air bag 4 will only expand toward the axis during the inflation process is that the diameter of the through hole opened in the center of the fixture shell 1 is larger than the diameter of the air-cooling piston nozzle valve angle head 8. When the air bag 4 is inflated, since the diameter of the through hole is larger than the diameter of the air-cooling piston nozzle valve angle head 8, the air bag 4 can only expand inward, that is, expand toward the axis. This design can ensure that the air bag 4 tightly wraps the air-cooling piston nozzle valve angle head 8 during the clamping process, provides a uniform clamping force, and prevents the air bag 4 from expanding outward. It can also allow the air bag 4 to be fully stretched in the vertical direction, so that it can be better clamped during the inflation process of the air bag 4. Figure 7 and Figure 8 As shown, the airbag 4 is in the shape of a ring, and the inner diameter of the airbag 4 in the uninflated state is larger than the diameter of the air-cooling piston nozzle valve angle head 8. The air pipe 3 is connected to the inside of the airbag 4, and the airbag 4 wraps the air-cooling piston nozzle valve angle head 8 when it is in the inflated state. Since the shape of the air-cooling piston nozzle valve angle head 8 may vary, the ring-shaped airbag 4 can better adapt to angle heads of different shapes. Compared with airbags 4 of other shapes, the ring-shaped airbag 4 can better wrap the air-cooling piston nozzle valve angle head 8 and provide uniform clamping force. And the ring-shaped airbag 4 can evenly clamp the air-cooling piston nozzle valve angle head 8 inward in the inflated state. Compared with airbags 4 of other shapes, the ring-shaped airbag 4 can maintain a relatively uniform clamping force distribution, thereby ensuring the accuracy and quality of assembly. Its structure is also relatively simple, easy to manufacture and install, and can effectively withstand the force and pressure during the clamping process.

[0027] See also Figure 6 A circular ring-shaped counterweight ring 6 is also fixedly installed on the bottom end surface of the clamp shell 1. The inner diameter of the counterweight ring 6 is smaller than the inner diameter of the clamp shell 1. The inner diameter of the airbag 4 when not inflated is equal to the size of the counterweight ring 6. The bottom end surface of the airbag 4 is fixedly installed on the top of the counterweight ring 6. An anti-slip surface 5 is provided on the inner ring surface of the airbag 4. In the fully automatic assembly equipment for the cooling piston nozzle valve, the function of the anti-slip surface 5 is to increase the friction between the airbag 4 and the air-cooling piston nozzle valve angle head 8, to ensure that the airbag 4 can tightly wrap the angle head during the clamping process, and provide a stable and uniform clamping force. The anti-slip surface 5 is made of rubber material and has good friction properties. When the airbag 4 is inflated, the friction between the anti-slip surface 5 and the surface of the air-cooling piston nozzle valve angle head 8 increases, preventing the airbag 4 from slipping during the clamping process, and ensuring that the airbag 4 can tightly wrap the angle head. Slippage may cause a decrease in assembly accuracy or assembly failure. The presence of the anti-slip surface 5 can effectively avoid this situation. Please refer to Figure 4 , an air pressure monitoring module 7 is also provided inside the airbag 4. The role of the air pressure monitoring module 7 in the fully automatic assembly equipment for the cooling piston nozzle valve is to monitor the air pressure inside the airbag 4 and provide a feedback signal to the control system to achieve control and regulation of the inflation process of the airbag 4. The air pressure monitoring module 7 can detect the air pressure changes inside the airbag 4 in real time. During the assembly process, by monitoring the inflation state of the airbag 4, it can be determined whether the airbag 4 has been inflated to a predetermined pressure level to ensure the stability and accuracy of the assembly. The air pressure monitoring module 7 can convert the detected air pressure signal into an electrical signal and feed it back to the control system. The control system can adjust the inflation pressure of the airbag 4 in real time according to these feedback signals to meet the requirements and goals of the assembly. By timely adjusting the inflation pressure of the airbag 4, the quality and effect of the assembly can be ensured.

[0028] Working principle: During use, first put the clamp shell 1 on the air-cooled piston nozzle valve angle head 8, and ensure that the counterweight ring 6 at the bottom of the clamp shell 1 is flush with the end face of the air-cooled piston nozzle valve angle head 8, then start the pneumatic module connected to the air pipe 3, and inflate the airbag 4 through the air pipe 3. During the inflation process, the airbag 4 will gradually expand and wrap the air-cooled piston nozzle valve angle head 8. At this time, an air pressure monitoring module 7 is provided inside the airbag 4 to monitor the internal air pressure of the airbag 4 and synchronously control the pneumatic module. When the air pressure monitoring module 7 detects that the internal air pressure of the airbag 4 is in a stable state and the pressure inside the airbag 4 no longer changes, it means that the airbag 4 completely fixes the air-cooled piston nozzle valve angle head 8. At this time, the next step of automated assembly can be carried out for the clamped air-cooled piston nozzle valve angle head 8.

[0029] When it is necessary to release the clamping of the air-cooling piston nozzle valve angle head 8, the pneumatic module only needs to be changed to the air extraction mode to shrink the airbag 4, so that the air-cooling piston nozzle valve angle head 8 can be released.
