Description

Technical Field

[0001] The utility model relates to the technical field of valve bodies, in particular to a machine tool for producing valve bodies. Background Technique

[0002] Before machining a valve body with a numerical control machine tool, it is necessary to clamp and position the valve body first to keep its position fixed. When clamping the valve body, T-shaped screws are placed in the T-shaped grooves of the bottom plate, and more than three pressing plates are used to press the valve body tightly on the workbench to fix its position. Since the position of clamping the valve body each time is random, accurate positioning of the valve body cannot be achieved after the pressing plate presses it. When programming the numerical control machine tool to machine the valve body, it is necessary to start programming from the origin of the coordinate system of the valve body. Therefore, this method requires finding the origin and tool setting again each time of clamping, and the advantages of the numerical control machine tool cannot be fully utilized. Since the existing method is to make the flange surface of the valve body fit and press tightly against the workbench surface to fix the valve body, only the upper top surface part of the valve body can be machined in one clamping. To machine other surfaces, re-clamping is required, which is cumbersome in operation, causes unnecessary labor, and has low efficiency.

[0003] After retrieval, the utility model patent with the authorization announcement number CN212371205U discloses a special positioning and clamping device for a numerical control machine tool for machining valve bodies, which includes a bottom plate, a circumferential rotation angle device, a chuck and three jaws. The circumferential rotation angle device is fixed on the bottom plate, the chuck is assembled on the circumferential rotation angle device, and the three jaws are radially clamped on the chuck. A support plate is fixed on the bottom plate, and the inner side surface of the support plate is parallel to the outer side surface of the chuck. A bolt ejector rod coaxial with the chuck is threadedly connected to the support plate. One end of the bolt ejector rod facing the chuck is provided with a pressing disc coaxial with the chuck, and the other end of the bolt ejector rod is provided with an adjusting handle. The structure of the utility model is simple, the operation is convenient, the positioning of the valve body is reliable, and it is not easy to swing, and the machining processes of multiple surfaces can be carried out, achieving the purpose of one-time positioning and machining multiple surfaces, and further improving the production efficiency;

[0004] In the above patent, although the valve body can be reliably positioned, is not easy to swing, and the machining processes of multiple surfaces can be carried out, achieving the purpose of one-time positioning and machining multiple surfaces, a large amount of waste chips will be generated during the actual machining process. If these waste chips are not removed in time, it will affect the subsequent valve body machining operation. Therefore, we propose a machine tool for producing valve bodies.

[0024] Full-range clamping mechanism 4: It includes a valve body lifting plate 43, a plate placement avoidance groove 44, and a primary positioning reference mark 45.

The primary positioning reference marks 45 are provided in the middle of the two placement abutment plates 3. The full-range clamping mechanism further includes servo cylinders 41 and clamping plates 42. The servo cylinders 41 are respectively arranged at the four corners of the outer surface of the interlayer 2. The telescopic ends of the servo cylinders 41 are fixedly connected to the clamping plates 42. Rubber interlayers are provided on the sides of the four clamping plates 42 facing the center of the machine tool 1. The lower ends of the clamping plates 42 are respectively fixedly connected to the upper ends of the valve body lifting plates 43 on the same side. The input ends of the servo cylinders 41 are electrically connected to the output ends of the control switch group 8. When valve body processing operations need to be carried out, the valve body to be processed can be manually positioned through the primary positioning reference mark 45, and the valve body to be processed is placed in the middle of the placement abutment plate 3. At this time, the control switch group 8 can be adjusted. The four servo cylinders 41 operate simultaneously. The telescopic ends of the four servo cylinders 41 extend by a specified length, and then drive the four clamping plates 42 to move relatively closer until they reach the specified position. At this time, the clamping plates 42 cooperate with the rubber interlayers to clamp the valve body to be processed;

[0025] Debris removal mechanism 6: It includes an avoidance groove 64 and a slag leakage hopper 65. The slag leakage hopper 65 is arranged in the middle of the lower surface of the machine tool 1.

At this time, the control switch group 8 can be adjusted. The four servo cylinders 41 operate simultaneously. The telescopic ends of the four servo cylinders 41 extend by a specified length, and then drive the four clamping plates 42 to move relatively closer until they reach the specified position. At this time, the clamping plates 42 cooperate with the rubber interlayer to clamp the valve body to be processed. At this time, the external air pump can be adjusted, and the two telescopic cylinders 62 operate simultaneously. The telescopic ends of the two telescopic cylinders 62 contract, and then drive the two placing abutting plates 3 to open. The two placing abutting plates 3 face downward and block the placing plate avoidance groove 44 at this time. At this time, the four valve body lifting plates 43 lift the valve body to be processed, and the four clamping plates 42 clamp the valve body to be processed from four directions. At this time, the external processing instrument can be installed inside the installation groove 7, and the external instrument polishes the clamped valve body. At this time, a large amount of debris is generated, and these debris fall onto the inclined placing abutting plate 3, and then, affected by gravity, fall into the slag box 9 along the slag leakage hopper 65.
