Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, and more specifically to a fire extinguisher valve assembly tooling. Background Technology

[0002] Fire extinguishers use driving pressure to spray a filled extinguishing agent, extinguishing fires by isolating oxygen, lowering temperature, and inhibiting combustion. Existing fire extinguishers typically include an extinguishing agent storage container, a spray device, a pressure device, an operating device, an indicating device, a handle / lifting ring, and markings. The fire extinguisher valve is the core control component, responsible for opening and closing the extinguishing agent spray channel and connecting the cylinder, spray device, and other key parts. Its performance directly affects the normal use and extinguishing effectiveness of the fire extinguisher. Fire extinguisher valve assembly fixtures are specialized process equipment used for the efficient and precise assembly of valve components (such as the valve body, seals, operating mechanism, and safety devices). Through standardized positioning, clamping, and auxiliary operations, they ensure assembly accuracy, improve production efficiency, and reduce human error.

[0003] For example, the prior art disclosure number CN217045342U describes an automatic assembly device for fire extinguisher valves. This utility model uses the cooperation between a vertical plate, a first connecting plate, a first fixing plate, and a fixing mechanism to fix the fire extinguisher, preventing it from moving during assembly. By setting a limiting mechanism, the valve can be clamped, which is convenient. By setting an assembly component, the clamped valve can be moved to the fire extinguisher nozzle and rotated to complete the assembly. No manual installation is required, reducing labor intensity and increasing production efficiency.

[0004] However, the existing technology described above still has the following problems in use: Traditional assembly fixtures require operators to first stop the entire fixture and then manually remove the two assembled fire extinguisher valve parts from the fixture. This process is time-consuming and labor-intensive, severely impacting the assembly efficiency of the fire extinguisher valve parts. Therefore, this utility model provides a fire extinguisher valve assembly fixture with high assembly efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a fire extinguisher valve assembly fixture. The fixture loads components while the assembly table rotates, automatically assembling two stacked fire extinguisher valve parts under the pressure block as the assembly table rotates. Furthermore, the assembled parts are automatically gripped by a mechanical claw and transported to a discharge plate, ultimately falling into a collection box. This automatic unloading effectively increases the assembly speed of fire extinguisher valve parts, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire extinguisher valve assembly fixture, including an assembly frame, an assembly platform on the top of the assembly frame, a plurality of mounting slots arranged in a circular array on the top of the assembly platform, a clamp for placing fire extinguisher valve parts fixed inside each mounting slot, a top plate fixed on the top of the assembly frame, a pressing block for pressing two fire extinguisher valve parts and a mechanical claw for unloading the parts at the bottom of the top plate, and a drive mechanism for driving the assembly platform to rotate fixed at the bottom of the assembly frame.

[0007] In a preferred embodiment, a first electric push rod is fixedly provided on the top of both the pressure block and the mechanical claw. The pressure block is connected to the top plate through the first electric push rod, and the pressure block is automatically raised and lowered by means of the first electric push rod, thereby improving the assembly speed of the fire extinguisher valve parts.

[0008] In a preferred embodiment, a through hole is provided on one side of the top plate, and a first electric push rod on the mechanical claw passes through the through hole. A second electric push rod is fixedly provided on the top of the top plate. The piston rod of the second electric push rod is fixed to the first electric push rod on the mechanical claw. By cooperating with the first and second electric push rods, the position of the mechanical claw can be automatically adjusted, thereby improving the feeding rate.

[0009] In a preferred embodiment, a feeding plate is fixedly provided on the top of one side of the assembly frame. The feeding plate is located in front of the mechanical claw, and a collection box is connected to the bottom of the feeding plate. The feeding plate and the collection box are designed to facilitate the collection of assembled fire extinguisher valve parts and facilitate centralized processing.

[0010] In a preferred embodiment, the drive mechanism includes a geared motor, which is fixed at the center of the bottom of the assembly frame, and the top end of the output shaft of the geared motor passes through the assembly frame and is fixed to the bottom of the assembly table.

[0011] In a preferred embodiment, an emergency stop button is fixedly provided at the front end of the assembly frame. The emergency stop button is connected to the reduction motor, the first electric push rod, the second electric push rod, and the mechanical claw via wires. When the operator discovers a problem in the assembly process, he can quickly press the emergency stop button to instantly cut off the power supply to these devices, causing the entire assembly fixture to stop all movements immediately and preventing the problem from becoming more serious.

[0012] In a preferred embodiment, the bottom of the assembly frame has multiple evenly distributed fixing holes, and multiple bolts are passed through the multiple fixing holes in sequence to firmly fix it, thereby improving stability.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention utilizes an assembly table that rotates while loading components. Two stacked fire extinguisher valve parts rotate with the assembly table to a position below a pressure block, whereby a first electric push rod drives the pressure block to press down, completing the automatic assembly. Furthermore, the assembled parts are automatically gripped by a mechanical claw and transported to a discharge plate, ultimately falling into a collection box, thus achieving automatic unloading and effectively improving the assembly speed of fire extinguisher valve parts.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figures 1-5This utility model provides a fire extinguisher valve assembly fixture, including an assembly frame 1. The top of the assembly frame 1 is provided with an assembly platform 2. The top of the assembly platform 2 has multiple mounting slots 3 arranged in a circular array. Each mounting slot 3 is fixedly provided with a clamp 4 for placing fire extinguisher valve parts. The top of the assembly frame 1 is fixedly provided with a top plate 5. The bottom of the top plate 5 is provided with a pressing block 6 for pressing two fire extinguisher valve parts and a mechanical claw 7 for unloading. The mechanical claw 7 is a mechanical device that can simulate the function of a human hand to realize actions such as grasping, carrying, and manipulating objects. The bottom of the assembly frame 1 is fixedly provided with a drive mechanism 8 for driving the assembly platform 2 to rotate.

[0023] The pressure block 6 and the mechanical claw 7 are both fixedly provided with a first electric push rod 9. The pressure block 6 is connected to the top plate 5 through the first electric push rod 9. A through hole 10 is opened on one side of the top plate 5. The first electric push rod 9 on the mechanical claw 7 passes through the through hole 10. A second electric push rod 11 is fixedly provided on the top of the top plate 5. The piston rod of the second electric push rod 11 is fixed to the first electric push rod 9 on the mechanical claw 7.

[0024] A feeding plate 12 is fixedly provided on the top of one side of the assembly frame 1. The feeding plate 12 is located in front of the mechanical claw 7, and a collection box 13 is connected to the bottom of the feeding plate 12.

[0025] In actual use, the two parts to be assembled for the fire extinguisher valve are first stacked into the fixture 4. The assembly table 2 rotates while feeding the parts. The two stacked valve parts rotate with the assembly table 2 to the bottom of the pressure block 6. At this time, the first electric push rod 9 between the pressure block 6 and the top plate 5 automatically extends, driving the pressure block 6 to press down on the parts, thereby automatically assembling the two parts into place. Then, the assembled parts are transported with the assembly table 2 to the bottom of the mechanical claw 7. The first electric push rod 9 between the mechanical claw 7 and the top plate 5 drives the mechanical claw 7 to move down and grab the assembled parts. Then, the second electric push rod 11 drives the first electric push rod 9 and the parts on the mechanical claw 7 to move to the right. When the parts are moved to the top of the unloading plate 12, the mechanical claw 7 is released, and the parts fall automatically into the collection box 13 through the unloading plate 12, thus completing the automatic unloading process.

[0026] Refer to the instruction manual appendix Figure 1 Figure 3 The drive mechanism 8 includes a geared motor 81, which is fixed at the bottom center of the assembly frame 1. The top end of the output shaft of the geared motor 81 passes through the assembly frame 1 and is fixed to the bottom of the assembly table 2. The geared motor 81 is a power transmission device that integrates a motor and a reduction mechanism. Its main function is to reduce the output speed of the motor and increase the output torque, thereby driving the assembly table 2 to rotate stably.

[0027] An emergency stop button 14 is fixedly installed at the front end of the assembly frame 1. The emergency stop button 14 is connected to the reduction motor 81, the first electric push rod 9, the second electric push rod 11 and the mechanical claw 7 by wires. The emergency stop button 14 is a safety control device that can quickly cut off the power supply to the equipment or stop the operation of the equipment in an emergency. When the staff finds a problem in the assembly process, they can quickly press the emergency stop button 14 to instantly cut off the power supply to the reduction motor 81, the first electric push rod 9, the second electric push rod 11 and the mechanical claw 7, so that the entire assembly fixture can stop all movements immediately and prevent the problem from becoming more serious.

[0028] To improve the stability of the entire assembly fixture, such as Figure 3 As shown, multiple evenly distributed fixing holes 15 are provided at the bottom of the assembly frame 1. Multiple bolts are passed through the multiple fixing holes 15 in sequence to firmly fix it, thereby improving stability.

[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
