Description

Technical Field

[0001] The utility model relates to the technical field of flange production, in particular to a tooling for a flange tapping machine with quick positioning. Background Technique

[0002] A flange is a pipe fitting used to connect two pipes or devices, and it has a wide range of applications in multiple industrial fields such as petroleum, chemical industry, food, medicine, textile, and machinery. During the production process of the flange, tapping processing needs to be carried out on the preset holes on its surface to generate internal threads on the inner wall of the holes, so as to facilitate the subsequent connection and fixation between flanges. Therefore, a corresponding tapping machine is born to realize this step of tapping processing of the flange holes.

[0003] After retrieval, the existing patent (publication number: CN209632231U) discloses a tapping mechanism for a tapping machine used for screw production, including an installation base and a reciprocating lead screw. A sliding groove is arranged on the installation base, a sliding seat is arranged in the sliding groove, a rotating motor is arranged on the sliding seat, a lead screw nut seat is arranged on the reciprocating lead screw, the lower end of the lead screw nut seat is fixed on the installation base, one end of the reciprocating lead screw is connected to the rotating motor, the other end of the reciprocating lead screw is connected to a tapping rotating shaft, the tapping rotating shaft is connected to a tapping head, and a temperature reduction linkage device is arranged on the installation base. The temperature reduction linkage device includes a support frame fixed on the installation base, a support rod fixed on the sliding seat, and an oil delivery tank fixed on the support frame. A driving gear is arranged on the support frame, and a horizontal rack is arranged at the upper end of the support rod. The reciprocating lead screw is used as a transmission component to simultaneously meet the driving requirements of linear feed and rotation, streamline the structure, reduce costs, and at the same time can achieve the precise output of tapping oil to avoid waste.

[0004] However, in the above scheme, it is inconvenient for quick positioning. During the tapping process, if the flange accidentally moves, it will seriously affect the tapping accuracy. Therefore, it needs to be positioned and locked before tapping. However, the existing ones are inconvenient for quickly positioning and locking the flange, which reduces the tapping processing efficiency of the flange to a certain extent and causes inconvenience in its use.

[0005] In view of this, the utility model proposes a tooling for a flange tapping machine with quick positioning. Content of the Utility Model

[0006] The utility model proposes a tooling for a flange tapping machine with quick positioning, which solves the problem of inconvenient quick positioning in the related technology.

[0007] The technical solution of the present utility model is as follows: A tooling for a flange tapping machine with quick positioning, including a machine body. One side of the top of the machine body is fixedly connected with a fixed frame. One side of the top of the fixed frame is fixedly connected with a hydraulic cylinder. The output end of the hydraulic cylinder penetrates through the fixed frame and is fixedly connected with a sliding plate. One side of the bottom end of the sliding plate is provided with a pressing component. The other side of the bottom end of the sliding plate is fixedly connected with a servo motor. The output end of the servo motor is fixedly connected with a tapping drill bit through a coupling. The other side inside the machine body is fixedly connected with a driving motor. The output end of the driving motor is fixedly connected with a processing table through a coupling. Clamping grooves are opened around the upper end of the processing table. The inner wall of the clamping groove is fixedly connected with an electric push rod. The output end of the electric push rod extends to the outside of the clamping groove and is fixedly connected with a clamping block. One side of the machine body is provided with a splash-proof component.

[0008] The pressing component includes a fixed box. The fixed box is fixedly connected to one side of the bottom end of the sliding plate. At the middle position of the inner top wall of the fixed box, a fixed rod is fixedly connected. The surface of the fixed rod is slidably connected with a movable plate. A return spring is wound around the surface of the fixed rod at the top end of the movable plate. The top end of the return spring is fixedly connected with the inner top wall of the fixed box. At both ends of the bottom end of the movable plate, sliding rods extending to the outside of the fixed box are fixedly connected. The bottom ends of the sliding rods are fixedly connected with a pressing plate. When the tapping drill bit descends for tapping, the elastic force of the return spring can be utilized to make the movable plate drive the sliding rods to descend, and then the pressing plate can drive the rubber pad to firmly and flexibly press and fix one side of the top end of the flange, avoiding accidental displacement and sliding of the flange during tapping.

[0009] Preferably, a rubber pad is fixedly connected to the bottom end of the pressing plate, and serrated grooves are opened at the bottom end of the rubber pad, improving the stability of the flexible pressing and fixing between the bottom end of the pressing plate and one side of the top end of the flange plate.

[0010] Preferably, a reserved groove is opened on the inner wall of the fixed box, and reserved blocks slidably matched with the inside of the reserved groove are fixedly connected to both sides of the movable plate, making the up and down sliding of the movable plate smoother and more stable.

[0011] Preferably, one side of the top view of the clamping block is arc-shaped, and four clamping blocks are evenly distributed at equal angles, facilitating the clamping and fixing of the four sides of the inner wall of the flange and improving its positioning firmness.

[0012] Preferably, the anti-splash component includes a filter box fixedly connected to one side of the bottom end of the machine body. A drain pipe is fixedly connected to the middle position of the bottom end of the filter box. A door body is hinged to one side of the filter box. Two ends of the upper end of the inner wall of the filter box are fixedly connected with guide plates. A chute is opened at one end of the bottom end of the guide plate. A filter frame is movably connected to the bottom end of the guide plate. Two ends of the top end of the filter frame are fixedly connected with sliding plates. One side of the top end of the machine body is fixedly connected with an anti-splash frame through bolts. The bottom end of the anti-splash frame is communicated with the inside of the filter box. The relatively high anti-splash frame can prevent the cooling oil sprayed during tapping from splashing too far. At the same time, the cooling oil and the debris generated by tapping flow into the inside of the filter box, and the filter frame is used to filter and screen them. At the same time, the sliding of the sliding plate inside the chute can facilitate the removal or installation of the filter frame from the inside of the filter box, thereby facilitating the centralized treatment of the debris filtered by the filter frame.

[0013] Preferably, the height of the anti-splash frame is higher than the overall height of the processing table, and the shape of the top view of the anti-splash frame is O-shaped, which can prevent the cooling oil sprayed during tapping from splashing too far and realize its anti-splash action.

[0016] Preferably, a drainage table is fixedly connected to one side of the top end of the machine body, and the shape of the drainage table is a frustum of a cone, which guides the sprayed cooling oil and debris and makes it more smooth to drain into the inside of the filter box through the through groove.

[0017] Preferably, a limiting groove is opened on the inner wall of the fixing frame, and a limiting block slidably matched with the inside of the limiting groove is fixedly connected to one side of the sliding plate, making the up and down sliding of the sliding plate more stable and enabling the vertical up and down tapping of the tapping drill bit, avoiding the inclination of the tapping drill bit and reducing the tapping accuracy.

[0018] The working principle and beneficial effects of the present utility model are as follows:

[0019] In this utility model, through the arranged pressing assembly, driving motor, clamping block and electric push rod, first start the electric push rod to drive the clamping block to move from the inside to the outside to clamp and fix the flange, realizing its rapid positioning. Then, when the tapping drill bit descends for tapping, the elastic force of the return spring can be utilized to make the movable plate drive the sliding rod to descend, and further make the pressing plate drive the rubber pad to firmly and flexibly press and fix one side of the top of the flange, avoiding the inadvertent displacement and sliding of the flange during tapping, ensuring the rapid positioning and locking of the flange, avoiding ensuring the accuracy during tapping. At the same time, after tapping one hole is completed, the driving motor can be started to drive the processing table to rotate to another hole, realizing automatic and rapid tapping, avoiding the cumbersome inconvenience of the traditional method of disassembling the flange and then repositioning and fixing the flange, improving its practicability and the working efficiency of tapping, and thus realizing the function of facilitating rapid positioning;

[0020] In this utility model, through the arranged anti-spray component, by using the relatively high anti-spray frame, it can avoid the cooling oil sprayed during tapping from splashing too far, resulting in the top of the machine body being too dirty and causing inconvenience for subsequent cleaning by the staff. At the same time, the cooling oil and the chips generated during tapping will be guided by the drainage table to fall into the filter box. At this time, the filter frame is used to filter and screen them, so that the filtered cooling oil is discharged through the drain pipe, facilitating its recycling. At the same time, the sliding of the sliding plate in the sliding groove can be utilized to facilitate the removal or installation of the filter frame from the filter box, and further facilitate the centralized treatment of the chips filtered by the filter frame, improving its practicability, and thus realizing the function of facilitating anti-spray collection.

[0031] The pressing component 5 includes a fixed box 503, which is fixedly connected to one side of the bottom end of the sliding plate 10. At the middle position of the inner top wall of the fixed box 503, a fixed rod 509 is fixedly connected. A movable plate 502 is slidably connected to the surface of the fixed rod 509. A return spring 508 is wound around the surface of the fixed rod 509 at the top end of the movable plate 502. The top end of the return spring 508 is fixedly connected to the inner top wall of the fixed box 503. At both ends of the bottom end of the movable plate 502, sliding rods 506 extending to the outside of the fixed box 503 are fixedly connected. The bottom ends of the sliding rods 506 are fixedly connected with a pressing plate 501. When the tapping drill bit 4 descends for tapping, the elastic force of the return spring 508 can be utilized to make the movable plate 502 drive the sliding rods 506 to descend, so that the pressing plate 501 can drive the rubber pad 505 to firmly and flexibly press and fix one side of the top end of the flange, avoiding accidental displacement and sliding of the flange during tapping.

[0035] On the basis of Embodiment 1, a preferred embodiment of the quick-positioning flange tapping machine tool provided by the present utility model is as follows Figures 1 to 6As shown: The anti-splash component 6 includes a filter box 602, which is fixedly connected to one side of the bottom end of the machine body 7. And a drain pipe 603 is fixedly connected to the middle position of the bottom end of the filter box 602. A door body 604 is hinged to one side of the filter box 602. And guide plates 606 are fixedly connected to both ends of the upper end of the inner wall of the filter box 602. A chute 609 is opened at one end of the bottom end of the guide plate 606. And a filter frame 605 is movably connected to the bottom end of the guide plate 606. Slide plates 608 are fixedly connected to both ends of the top end of the filter frame 605. An anti-splash frame 601 is fixedly connected to one side of the top end of the machine body 7 by bolts. And the bottom end of the anti-splash frame 601 is communicated with the inside of the filter box 602. By using the relatively high anti-splash frame 601, it is possible to prevent the cooling oil sprayed during tapping from splashing too far. At the same time, the cooling oil and the chips generated by tapping flow into the inside of the filter box 602 and are filtered and screened by the filter frame 605. At the same time, the filter frame 605 can be taken out or installed from the inside of the filter box 602 regularly, thereby facilitating the centralized treatment of the chips filtered by the filter frame 605.

[0036] In this embodiment, the height of the anti-splash frame 601 is higher than the overall height of the processing table 9. And the shape of the top view of the anti-splash frame 601 is O-shaped. By using the relatively high and O-shaped anti-splash frame 601, it is possible to prevent the cooling oil sprayed during tapping from splashing too far.

[0037] In this embodiment, the inclination angle of the top end of the guide plate 606 with respect to the horizontal direction is 30 degrees. And the cross-sectional shape of the guide plate 606 is a right trapezoid. By using the guide plate 606 with an inclined top end, it is possible to guide the cooling oil and chips flowing into the inside of the filter box 602, facilitating their centralized discharge into the inside of the filter frame 605 for filtering and screening.

[0038] In this embodiment, a sliding structure is formed between the inside of the slide plate 608 and the chute 609. And the cross-sectional shapes of the slide plate 608 and the chute 609 are inverted convex shapes. By using the sliding of the inverted convex slide plate 608 inside the chute 609, the firm stability of the sliding installation between the filter frame 605 and the bottom end of the guide plate 606 is improved.

[0039] In this embodiment, a drainage table 607 is fixedly connected to one side of the top end of the machine body 7. And the shape of the drainage table 607 is frustum-shaped. By using the frustum-shaped drainage table 607, it is possible to guide the sprayed cooling oil and chips, making it more smooth for them to be discharged into the inside of the filter box 602 through the through groove.

[0040] In addition, a limit groove 12 is opened on the inner wall of the fixing frame 2. And a limit block 11 that is slidably matched with the inside of the limit groove 12 is fixedly connected to one side of the sliding plate 10. By using the sliding of the limit block 11 inside the limit groove 12, the up and down sliding of the sliding plate 10 is made more stable. And vertical up and down tapping of the tapping drill bit 4 can be realized, preventing the tapping drill bit 4 from tilting and reducing the tapping accuracy.

[0041] Working principle and usage process of the present utility model: First, place the flange on the top of the processing table 9. Then, start the electric push rod 14 to drive the clamping block 13 to move from the inside to the outside to clamp and fix the flange, achieving its rapid positioning. Then, start the driving motor 8 to drive the processing table 9 to rotate, so that one of the holes on the flange can be aligned directly below the tapping drill bit 4. Next, start the hydraulic cylinder 1 to drive the sliding plate 10 to descend. At this time, the rubber pad 505 will first contact one side of the top of the flange, and use the reaction force to make the pressing plate 501 rise and drive the sliding rod 506 to slide, so that the movable plate 502 slides inside the fixed rod 509 and compresses the return spring 508. Furthermore, the elastic force of the return spring 508 can be utilized to make the movable plate 502 drive the sliding rod 506 to descend, and then the pressing plate 501 can drive the rubber pad 505 to firmly and flexibly press and fix one side of the top of the flange, preventing the flange from accidentally shifting and sliding during tapping.

[0042] After that, when the bottom end of the tapping drill bit 4 contacts the top of the flange, start the servo motor 3 to drive the tapping drill bit 4 to rotate, realizing the tapping process for the holes on the flange. At the same time, spray cooling oil through an external conduit to cool the tapping area of the tapping drill bit 4. After tapping one hole, the hydraulic cylinder 1 can be started to drive the tapping drill bit 4 to rise above the flange, and then the driving motor 8 is started to drive the processing table 9 to rotate, so that another hole on the flange is directly below the tapping drill bit 4. Then, repeat the above operations to realize the tapping processing of multiple holes on the flange, avoiding the cumbersome inconvenience of having to disassemble the flange, rotate it, and then position and fix the flange after tapping one hole, and improving the working efficiency of flange tapping.

[0043] Meanwhile, by using the relatively high anti-splash frame 601, it can prevent the cooling oil sprayed during tapping from splashing too far. At the same time, the cooling oil and the debris generated by tapping will be guided by the drainage table 607 and fall into the internal part of the filter box 602. At this time, the guide plate 606 is used to guide again, making it flow concentratedly into the internal part of the filter frame 605. Then, the filter frame 605 can be used to filter and screen it, so that the filtered cooling oil is discharged through the drain pipe 603, facilitating its recycling. At the same time, after the tapping processing is completed, the door body 604 can be opened, and then the filter frame 605 is pulled, so that the sliding plate 608 slides inside the sliding groove 609 until it is completely taken out from the internal part of the filter box 602, facilitating the centralized treatment of the debris filtered by the filter frame 605. During installation, the sliding plate 608 is slid into the internal part of the sliding groove 609, improving the smoothness and firmness of the sliding installation of the filter frame 605 inside the filter box 602.

[0044] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
