Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of band saw cutting tooling, specifically relating to a band saw cutting tooling with upper and lower support inclined surfaces for valves. Background Technology
[0002] The circular electric sealed isolation valve body structure consists of two cylindrical components: an upper support and a lower support. When processing these two components, it is first necessary to cut the material with a band saw, then cut beveled surfaces at the ends of the components before splicing them together.
[0003] However, current band saws cannot clamp tilted components when processing cylindrical parts because the pneumatic grippers on both sides of the machine are symmetrically arranged, thus preventing tilted cutting.
[0004] To solve this problem, a special auxiliary tooling needs to be made before each cutting. The auxiliary tooling includes a rectangular main board with inclined limiting grooves on the sides. In order to ensure that the component to be cut does not shift during the cutting process, the end of the component to be cut needs to be inserted into the limiting groove and welded to fix it. Then, the pneumatic jaws of the machine tool are used to clamp the main board so that the component to be cut is kept inclined during the cutting.
[0005] However, this method requires cutting off the auxiliary tooling welded to the material head after cutting and grinding the surface of the processing components. The steps are cumbersome, the band saw cutting efficiency is low, and it increases the labor intensity of the workers. Utility Model Content
[0006] To address the problems existing in the prior art, this utility model provides a valve upper and lower support inclined band saw cutting fixture. By using pneumatic grippers to hold the deformation areas on both sides of the limiting groove, the limiting groove is slightly contracted, thereby clamping and fixing the component to be cut inside the limiting groove. This prevents the component from being removed from the limiting groove and forms a tight fixation with the main board. This eliminates the need for welding and subsequent cutting and grinding auxiliary fixtures, greatly simplifying the operation process, improving the band saw cutting efficiency, and reducing the labor intensity of workers.

DETAILED DESCRIPTION
[0020] The utility model will be further described below in combination with the drawings and specific embodiments:
[0021] As shown in the specific embodiments, Figures 1-3 The arrow direction in the drawing is the clamping direction of the pneumatic clamping jaw.
[0022] The utility model provides a kind of valve upper and lower support bevel band saw blanking tool, including main plate 1, the pneumatic clamping jaw on machine tool clamps the two sides of main plate 1 and forms fixed, the limiting groove 3 of being inserted with the component to be cut 2 is cooperated with the side of main plate 1 and is set, the limiting groove 3 is inclined and is set, the region of the two sides of main plate 1 in limiting groove 3 is formed into deformation area 4, the region of main plate 1 between the two sides of deformation area 4 is formed into elastic area 9, the two sides of deformation area 4 are connected by means of elastic area 9, the two sides of deformation area 4 have the tendency of gathering to elastic area 9 by the clamping of pneumatic clamping jaw, the component to be cut 2 in limiting groove 3 is clamped and fixed by the gathering of the two sides of deformation area 4.
[0023] The band saw machine of present is in the processing cylindrical component to be cut 2, since the pneumatic clamping jaw on machine tool two sides is symmetrically set, cannot clamp inclined component to be cut 2, thus cannot carry out inclined blanking, thus all need to make special auxiliary tool, auxiliary work includes a rectangular main plate 1, the side of main plate 1 is provided with the limiting groove 3 of being inclined, in order to guarantee that component to be cut 2 does not deviate during cutting saw, need to be inserted with limiting groove 3 with the end of component to be cut 2 and carry out welding fixed, then the pneumatic clamping jaw of machine tool is clamped with main plate 1, to carry out cutting saw in the state of keeping component to be cut 2 inclined.But this method needs to cut down auxiliary tool after blanking and polish the surface of processing component, step is more complicated, band saw blanking efficiency is low and increases the labor intensity of staff.
[0024] Because the main plate 1 in the utility model is additionally provided with deformation area 4, although limiting groove 3 is cooperated with the shape of component to be cut 2, but component to be cut 2 can still be taken out relatively easily, but when pneumatic clamping jaw clamps main plate 1, Figure 2As shown in the diagram, the arrows indicate the clamping direction of the pneumatic grippers, and label 10 represents the cutting saw blade 10 of the machine tool. Under the external force of the pneumatic grippers on both sides of the limiting groove 3, the deformation zones 4 on both sides undergo slight elastic deformation centered on the elastic zone 9. This causes the opening side of the limiting groove 3 to slightly contract, thereby clamping and fixing the component 2 to be cut within the limiting groove 3, preventing the component 2 from being removed from the limiting groove 3 and forming a tight fixation with the main board 1. Compared to the traditional welding fixing method, this fixture eliminates the need for welding and subsequent cutting and grinding auxiliary fixtures, greatly simplifying the operation process, improving the efficiency of band saw cutting, and reducing the labor intensity of the workers.
[0025] like Figure 1 and Figure 3 As shown, the elastic zone 9 is provided with a deformation groove 5 that penetrates the main board 1 vertically. The opening side of the deformation groove 5 is connected to the horizontal side of the limiting groove 3. The length direction of the deformation groove 5 is perpendicular to the clamping direction of the pneumatic gripper. The deformation zone 4 converges towards the center along the deformation groove 5 by means of the clamping of the pneumatic gripper. In order to realize the deformation of the limiting groove 3, the present invention provides a deformation groove 5 at the inner center of the limiting groove 3, thereby providing deformation space for the deformation zone 4, so that the pneumatic gripper can clamp the limiting groove 3 with a small force to form a contraction to clamp and fix the component 2 to be cut.
[0026] like Figures 1-3 As shown, clamping side plates 6 are provided on both sides of the limiting groove 3. The inner side of the clamping side plate 6 abuts against the limiting groove 3, and the outer side of the clamping side plate 6 is flush with the side of the main board 1. The component to be cut 2 is clamped and fixed by means of the clamping side plates 6 on both sides. The clamping side plate 6 is welded to the main board 1 as a whole. The clamping side plate 6 can increase the limiting range of the limiting groove 3, making it easier to clamp the component to be cut 2 and preventing the component to be cut 2 from rotating during the feeding process.
[0027] like Figure 1 As shown, a grid-like friction pattern 7 is provided on the contact surface between the clamping side plate 6 and the component to be cut 2. The horizontal lines of the friction pattern 7 are at an angle of 30-60° to the horizontal plane. By setting the friction pattern 7, the friction force between the clamping side plate 6 and the component to be cut 2 is increased, thereby further preventing the component to be cut 2 from rotating during the cutting process and ensuring the cutting quality of the band saw.
[0028] like Figures 1-2 As shown, a support plate 8 perpendicular to the motherboard 1 is also provided below the motherboard 1. The length direction of the support plate 8 is parallel to the clamping direction of the pneumatic gripper. The bottom surface of the clamping side plate 6 and the bottom surface of the support plate 8 are on the same horizontal plane. The support plate 8 can ensure the stability of the tooling placement and can make the plane of the axis of the component to be cut 2 overlap with the plane of the motherboard 1, ensuring the clamping stability of the limit groove 3 on the component to be cut 2.
