Description

Technical Field

[0001] The utility model belongs to the technical field of valve component processing, and in particular relates to a fixture for integrally processing a plurality of valve components. Background Art

[0002] When processing the inner hole of the valve cover, the valve part is generally clamped and tightened by a fixture, and then the inner hole of the valve part is processed by a rotating tool. However, when processing valve parts, the existing device can generally only process one valve part at a time. When processing the next valve part, the previous valve part needs to be disassembled, and then the next valve part needs to be clamped. At this time, the tool is in an inoperative state, and it is difficult to prepare the clamped valve part, which makes the processing efficiency of the valve part low. In addition, the general fixed clamping device has only one clamping method. Some valve parts cannot be processed in one time and need to be used in conjunction with other processing devices. Since only part of the area can be clamped, multiple clamping and movement are required to complete the processing of the entire workpiece, which increases the complexity and difficulty of the operation. Since multiple clamping and movement are required, the processing time may be extended, affecting production efficiency.

[0003] The existing authorization number is CN 217965149 U, which discloses a plurality of valve assembly integral processing fixtures, the fixture assembly includes at least two clamping blocks and a clamping through hole for placing a nut between at least two clamping blocks, the clamping blocks are movable so that at least two clamping blocks have an assembly position away from each other to expand the clamping through hole and a clamping position close to each other to reduce the clamping through hole, the side of the clamping block close to the limited clamping through hole is raised upward to form a support boss, when at least two clamping blocks are in the assembly position and the valve stem nut is set in the limited clamping through hole, the convex ring part is set above the support boss and the outer peripheral surface of the convex ring part is flush with the outer side surface of the support boss or protrudes relative to the outer side surface of the support boss. The convex ring part of the outer periphery of the valve stem nut is flush with the outer side surface of the support boss or protrudes relative to the outer side surface of the support boss, thereby increasing the distance between the convex ring part of the outer periphery of the valve stem nut and the upper surface of the clamping block, which is more convenient to take.

[0004] However, the functionality of the above-mentioned fixture for integrally processing multiple valve assemblies is relatively poor. The device clamps the valve components and then processes them using multiple processing cutter heads. It may be necessary to hire more workers to operate and control the multiple cutter heads. This will lead to an increase in labor costs and may increase labor intensity and work risks. When multiple cutter heads are running at high speeds, they may cause safety issues such as large noise and vibration. In addition, if collisions or damage occur between the cutter heads, serious accidents and losses may occur. At the same time, the practicability of the device is relatively poor. The device has high requirements for the valve components to be processed. If a three-port valve component is to be processed, it is necessary to equip it with other clamping devices for use in conjunction to achieve complete processing of the valve component, which is rather troublesome. Therefore, it is necessary to propose a fixture for integrally processing multiple valve components to solve the above-mentioned problems. Utility Model Content

Two groups of through-type screw hole structures are opened on the outer side of the clamping claw, and the clamping claw is threadedly connected to the top of the fixing seat in a circular array.

DETAILED DESCRIPTION

[0027] Please refer to Figure 1-6 A fixture for integrally processing multiple valve components, comprising: a workbench 1, the bottom of the workbench 1 is rotatably connected to a support column 2 for supporting it, the top of the workbench 1 is installed with a clamping device for fixing a valve member 8, a support platform 5 for fixing the bottom of the clamping device is fixedly arranged on the support column 2, a frame 6 is fixed next to the workbench 1, and a processing drill 7 for processing the valve member 8 is arranged on the frame 6.

[0028] Furthermore, the support column 2 is rotatably connected to the workbench 1. The workbench 1 is a circular turntable structure. The workbench 1 can be driven to rotate by the rotating structure on the support column 2, so that the device can be processed continuously. The support table 5 is fixed on the support column 2. The support table 5 supports the control device 44 and the cylinder body 33 of the clamping device installed on the workbench 1. The valve parts that rotate to the bottom are processed in sequence using a processing cutter head. By fixing multiple valve parts on the workbench, the valve parts that rotate to the bottom are processed in sequence using a processing cutter head. The next valve body can be clamped and processed by rotating the workbench, and processing can be achieved while clamping. In order to improve the processing efficiency of the valve body, movement or collision can be avoided during the processing process, thereby improving the efficiency and accuracy of the entire processing process. Since multiple valve parts are fixed, the time and workload of manual operation and adjustment are reduced, and the labor cost is reduced. At the same time, the rotatable workbench can also enable workers to operate more flexibly, thereby improving production efficiency.

[0029] Furthermore, the clamping device includes a chuck fixing device 3 and a snap-fit ​​fixing device 4. Two groups of chuck fixing devices 3 and snap-fit ​​fixing devices 4 are respectively arranged on the workbench 1. Different positions of the valve component 8 can be processed according to requirements. The use of two different clamping devices can flexibly adapt to the clamping and fixing of various valve components. Various different types of valve components can be processed on the same device. The two different types of clamping devices improve the utilization rate of the equipment, reduce the time and work for changing the fixture, make the operation on the workbench more intensive, thereby improving the adjustment of the entire work and improving the processing efficiency and high efficiency.

[0030] Furthermore, the chuck fixing device 3 includes a claw 31, a fixing seat 32 and a cylinder body 33. Two groups of through-type screw hole structures are opened on the outer side of the claw 31. The claw 31 is threadedly connected to the top of the fixing seat 32 in a ring array. Six groups of claws 31 form a complete fixing structure, and the fixing seat 32 is fixed on the elastic film. The cylinder body 33 controls the air pressure, which drives the claw 31 to expand and contract the inner wall of the valve member 8.

[0031] Further, the clamping and fixing device 4 includes a fixing block 41, a connecting rod 42, a clamping base 43 and a control device 44. The fixing block 41 is provided with a groove matching the valve member 8. Two connecting rods 42 are fixedly arranged at the bottom of the fixing block 41, and a slide groove for the connecting rods 42 to slide is provided on the clamping and base. The clamping base 43 is provided with a groove matching the valve member 8, and cooperates with the two sets of fixing blocks 41 to fix the bottom and side of the valve member 8. The movement of the connecting rod 42 is controlled by the control device 44 to drive the fixing block 41. For clamping the valve member 8, the cylinder can quickly move and lock the claws through compressed air, thereby improving the processing speed and efficiency. The pneumatic film chuck can accurately control the position and pressure of the chuck to ensure that the workpiece is firmly clamped and will not be damaged. The valve members that are not suitable for the chuck fixing device can be processed. By fixing the two sides and the bottom of the valve member with three or four holes, the top of the valve member can be processed. A groove that matches the valve member is provided on the clamping base, which reduces the damage caused by the displacement of the valve member during processing and improves the accuracy of valve member processing.

[0032] The working principle of the multi-valve assembly integral processing fixture provided by the utility model is as follows:

[0033] The first step is to ensure that the device and fixture are in good condition, clean the surface of the workbench 1, and connect the device to the power source. In addition, the valve member 8 needs to be prepared.

[0034] The second step: according to the processing needs, the valve component 8 is put on the claw 31, and the claw 31 is controlled by the cylinder body 33 to fix the inner wall of the valve component 8, or the bottom of the valve body is fixed to the card and base 43, and the fixing block 41 is controlled by the control device 44 to clamp and fix the valve component 8, and ensure that its position is correct and stable.

[0035] The third step: start the device to rotate the workbench 1 so that the first valve component 8 on the workbench is aligned with the processing drill bit 7, and then the processing drill bit 7 rotates and moves to realize the processing of the first valve component 8. After the processing is completed, the workbench 1 is controlled to rotate so that the second valve component 8 is aligned with the processing drill bit 7. At this time, the first processed valve component 8 is disassembled, and then a new valve component 8 is clamped. Based on the above, one valve component 8 can be processed and the other valve component 8 can be disassembled and assembled, thereby improving the processing efficiency of the valve component 8.

[0036] Step 4: Pay attention to safety during the processing and wear personal protective equipment, such as gloves, goggles, etc. to prevent accidents. After completing the processing, clean the workbench 1 and return all tools to their positions.
