Description

Technical Field

[0001] The utility model relates to the technical field of valve casting processing equipment, and particularly relates to a processing base for valve castings. Background Technique

[0002] A casting is a metal formed object obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, through subsequent processing means such as grinding, an object with a certain shape, size and performance is obtained. When processing valve castings, there is a step of grinding the outside of the valve, so before processing, clamping equipment is mostly used to fix the valve castings.

[0003] During the operation of valve castings, including installing and disassembling the castings in the clamping equipment, since it is necessary to ensure the stability of the valve castings, the clamping force of the clamping equipment is often large, so it is easy to cause bumps and scratches on the clamping end face of the valve castings during the operation, which has an adverse impact on the processing quality of the valve castings. At this time, secondary grinding will undoubtedly reduce the production efficiency of the valve castings. Content of the Utility Model

[0025] Please refer to Figures 1-3 , the present utility model provides a processing base for valve castings, including a base 1. At both ends of the top of the base 1, a base 2 and a fixed seat 3 are respectively arranged. On one side of the outer wall of the base 2, an electric push rod 4 is fixedly connected. The telescopic end of the electric push rod 4 penetrates through the base 2 and is fixedly connected with a movable seat 5. Among them, the bottom of the movable seat 5 is slidably connected with the top of the base 1. Limiting grooves corresponding to the movable seat 5 are respectively opened at both bottoms of the base 2 to limit the horizontal movement direction of the movable seat 5 and ensure the stability of its movement.

[0026] On one side close to each other of the fixed seat 3 and the movable seat 5, a positioning component 6 is arranged. At the center of the side of the movable seat 5 far from the fixed seat 3, a rotary motor 7 corresponding to the positioning component 6 is fixedly connected.

[0027] The positioning component 6 includes a turntable 601. An indexing plate 602 is arranged outside the turntable 601, and a locking bolt 603 is arranged at the center of the indexing plate 602. Among them, the turntable 601 located on the fixed seat 3 is connected to the fixed seat 3 by a bearing, and the turntable 601 located on the movable seat 5 is fixedly connected to the driving shaft of the rotary motor 7. When the rotary motor 7 is started, it is convenient to drive the turntable 601 to rotate, thereby driving the valve casting to rotate and facilitating the staff to adjust the angle of the valve casting.

[0028] The locking bolt 603 penetrates through the indexing plate 602 and is threadedly connected to the turntable 601. A threaded hole corresponding to the locking bolt 603 is opened at the center of the interior of the turntable 601. It is convenient to fix between the turntable 601 and the indexing plate 602 through the locking bolt 603, and at the same time, it is convenient to disassemble and replace the indexing plate 602 to adapt to valve castings with flanges of different sizes and specifications.

[0029] In this embodiment, a plug rod 604 is fixedly connected to the outer wall of the indexing plate 602. A jack 605 corresponding to the plug rod 604 is opened on the side of the turntable 601 close to the indexing plate 602. The plug rod 604 and the jack 605 are in one-to-one correspondence and fit. Through the plugging combination of the plug rod 604 and the jack 605, it is convenient to quickly position and install the indexing plate 602.

[0030] An anti-slip rubber pad 608 is fixedly connected to the surface of the indexing plate 602. The anti-slip rubber pad 608 is made of rubber. When clamping the valve casting, it contacts the end face flange, which can not only play an anti-slip role, but also play a buffering and protecting role to prevent damage to the end face of the valve casting.

[0031] On one side of the indexing plate 602 close to the center of the base 1, a receiving hole 606 is opened, and a positioning column 607 is threadedly connected inside the receiving hole 606.

[0032] A through groove 8 is provided at the center of the top of the base 1. A conveyor belt 10 is arranged at the bottom of the through groove 8. Brackets 9 corresponding to the conveyor belt 10 are fixedly connected to both sides of the base 1.

[0033] A receiving groove corresponding to the conveyor belt 10 is provided inside the base 1. The conveyor belt 10 passes through the receiving groove and is located at the bottom of the through groove 8. The conveyor belt 10 is driven by a servo motor installed outside the bracket 9. The servo motor is connected to an external power supply. The waste generated during the processing can pass through the through groove 8 and fall on the conveyor belt 10 for conveying, realizing the real-time conveying and cleaning of the waste, effectively avoiding the accumulation of waste at the bottom of the valve casting, and making the working environment cleaner.

[0034] During use, first, according to the flange style of the valve casting to be processed, a corresponding and fitting positioning disk 602 is installed on the surface of the turntable 601. Then, the positioning columns 607 are screwed out. Specifically, when operating, it is not necessary to screw out all the corresponding positioning columns 607. Only a certain number of positioning columns 607 are evenly extracted from the periphery of the positioning disk 602, and then they can be inserted into the screw holes at both ends of the valve casting to be processed.

[0035] Subsequently, the electric push rod 4 is connected to an external power supply and started, driving the movable seat 5 to slide on the top of the base 1 and approach the fixed seat 3. Only the positioning disks 602 in the two positioning assemblies 6 are needed to limit the two ends of the valve casting to be processed, and there is no need for strong clamping, which is convenient for protecting the end face quality of the valve casting to be processed.

[0036] In this device, the rotating motor 7 is a servo motor, and the drive shaft can be self-locked. During the grinding process, the stability of the valve casting to be processed can be ensured, that is, it does not translate or rotate.

[0037] During the processing, by starting the rotating motor 7, the turntable 601 and the valve casting to be processed between the two positioning disks 602 can be driven to rotate to adjust the angle of the valve casting, making it more convenient for the staff to process.

[0038] All kinds of waste chips generated during the processing fall on the top of the base 1, pass through the through groove 8 and then fall on the surface of the conveyor belt 10. When the conveyor belt 10 is started during work, the waste can be moved and discharged in real time, thereby avoiding the accumulation of waste at the bottom of the valve casting and affecting the processing. The surface of the conveyor belt 10 in this device is a conveyor belt, and the middle of the conveyor belt is slightly concave to support the conveying of solid-liquid mixtures.

[0039] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
