Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a positioning tooling for flange processing. Background Technique

[0002] The flange is simply called a flange, which is just a general term. Usually, it refers to a disc-shaped metal body with several fixing holes on its periphery for connecting other things. It is widely used in machinery. Flanges often need to be processed in cooperation with positioning tooling.

[0003] Prior art such as a flange and its processing positioning tooling disclosed in a patent document with the publication number of CN115446628A includes a disc and a rotating assembly. The surface of the disc is provided with arc surfaces, and the number of the arc surfaces is 6. A convex ring is welded on the top of the disc, and a mounting hole is opened on the top of the disc. The disc and the convex ring are of an integral structure, including a base. A circular frame is movably embedded and connected to the top of the base. A first ball is arranged between the base and the circular frame. The rotating assembly is installed on the surface of the base. The present invention solves the problems that the existing positioning tooling is rather troublesome when positioning and clamping the flange blank during the processing of the flange. The processing positioning tooling can only position the flange provided with positioning holes, which not only affects the processing efficiency but also increases the processing cost. At the same time, when the processing positioning tooling fixes the flange, it will affect the processing of the hole positions, and it is necessary to adjust the clamping position multiple times, with complex operations and time-consuming and laborious.

[0004] Currently, most flanges are often internally supported by clamping blocks. Due to the complex structure, the production cost of the equipment is increased. At the same time, since there are threads inside the flange, during the tightening operation, the threads are easily worn due to force, resulting in damage to the flange and increasing the economic loss of the producer. Therefore, improvements are needed. Content of the Utility Model

[0005] The purpose of the utility model is to at least partly solve the disadvantages in the prior art, and a positioning tooling for flange processing is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A positioning tooling for flange processing, including a workbench, the lower surface of the workbench is fixedly connected with supporting feet, a fastening device is arranged on the surface of the workbench, the fastening device includes a screw rod, the screw rod is in threaded connection with the inner wall of the workbench, the upper end of the screw rod is fixedly connected with a pressing disc, a positioning groove is arranged on the upper surface of the workbench, a resisting block is slidably connected to the inner wall of the positioning groove, one side of the resisting block is fixedly connected with a supporting plate, and an auxiliary device is arranged on the surface of the workbench. This scheme has a simple structure and low production cost. At the same time, this scheme uses a rubber block to contact the flange, effectively reducing the wear of the internal threads of the flange and reducing the economic loss of the producer.

[0007] Preferably, a rubber block is fixedly connected to the side of the support plate away from the abutting block, and one side of the rubber block is arc-shaped. When processing the flange, place the flange on the workbench, then rotate the nut. The nut drives the pressing disc and the screw rod to rotate. Subsequently, the pressing disc moves downward, the pressing disc presses the abutting block, and the abutting block then displaces in the direction away from the screw rod. The stabilizing spring deforms under force. Subsequently, the rubber block presses the inner ring of the flange, and the flange is then firmly supported, and the flange can be processed. After the processing operation is completed, only need to rotate the nut in the reverse direction. Subsequently, the pressing disc loses the extrusion on the abutting block, and the stabilizing spring pushes the abutting block, the support plate and the rubber block to reset.

[0008] Preferably, a stabilizing spring is fixedly connected to one side of the abutting block. The stabilizing spring is located in the positioning groove, and the end of the stabilizing spring away from the abutting block is fixedly connected to the inner wall of the positioning groove to ensure that the abutting block resets after losing the extrusion of the extrusion block.

[0009] Preferably, the lower edge of the pressing disc is chamfered, and a nut is fixedly connected to the upper surface of the pressing disc to facilitate adjusting the position of the pressing disc.

[0010] Preferably, the number of the positioning grooves and the abutting blocks is three each, and the three positioning grooves and the abutting blocks are arranged in a circumferential array to stably position the flange.

[0011] Preferably, the auxiliary device includes a support rod. The support rod slides on the inner wall of the workbench. A cushion block is fixedly connected to the upper end of the support rod, and a stabilizing frame is fixedly connected to the lower end of the support rod. A sliding sleeve is fixedly connected to the lower surface of the workbench. A control rod is slidably connected to the inner wall of the sliding sleeve. One end of the control rod is beveled, and a pull ring is fixedly connected to one end of the control rod. This solution can assist in discharging the flange, reduce the tight fit between the flange and the workbench surface, and make it difficult for the user to remove it, ensuring the normal use of the equipment.

[0012] Preferably, a return spring is fixedly connected to the upper surface of the stabilizing frame. The return spring is sleeved on the support rod, and the end of the return spring away from the stabilizing frame is fixedly connected to the lower surface of the workbench. Push the pull ring in the direction close to the workbench. The pull ring pushes the control rod to displace. The control rod pushes the stabilizing frame, the support rod and the cushion block upward. The return spring deforms under force. Subsequently, the cushion block supports the flange, and then the user can remove the flange. Subsequently, pull the pull ring in the direction away from the workbench, and the pull ring drives the control rod to reset, facilitating subsequent operations.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] In the present utility model, when processing a flange, the flange is placed on the workbench. Subsequently, the nut is rotated, and the nut drives the pressing disc and the screw rod to rotate. Then, the pressing disc moves downward, and the pressing disc presses against the abutting block. The abutting block then displaces in a direction away from the screw rod, and the stabilizing spring deforms under force. Subsequently, the rubber block presses against the inner ring of the flange, and the flange is immediately fastened and lifted, enabling the processing of the flange. After completing the processing operation, only the nut needs to be rotated in the reverse direction. Then, the pressing disc loses the extrusion force on the abutting block, and the stabilizing spring pushes the abutting block, the supporting plate, and the rubber block to reset. Then, the pull ring is pushed in the direction close to the workbench, and the pull ring drives the control rod to displace. The control rod pushes the stabilizing frame, the supporting rod, and the cushion block upward, and the reset spring deforms under force. The cushion block then lifts the flange, and then the user can remove the flange. Then, the pull ring is pulled in the direction away from the workbench, and the pull ring drives the control rod to reset, facilitating subsequent operations. The structure of this solution is simple, and the production cost is low. At the same time, this solution uses a rubber block to contact the flange, effectively reducing the wear of the internal thread of the flange, reducing the economic losses of producers, and can assist in blanking the flange, reducing the situation where the flange fits tightly with the workbench surface and is difficult for the user to remove, ensuring the normal use of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figures 1-5 For this utility model, a technical solution is provided: a positioning tooling for flange processing, including a workbench 1. Fixedly connected to the lower surface of the workbench 1 are support feet 2. Arranged on the surface of the workbench 1 is a fastening device 3. The fastening device 3 includes a screw rod 31, which is threadedly connected to the inner wall of the workbench 1. Fixedly connected to the upper end of the screw rod 31 is a pressing disc 32. Arranged on the upper surface of the workbench 1 is a positioning groove 34. Slidingly connected to the inner wall of the positioning groove 34 is a resisting block 37. Fixedly connected to one side of the resisting block 37 is a supporting plate 38. Arranged on the surface of the workbench 1 is an auxiliary device 4. This solution has a simple structure and low production cost. At the same time, this solution uses a rubber block 36 to contact the flange, effectively reducing the wear of the internal thread of the flange and reducing the economic loss of the producer.

[0023] Specifically, fixedly connected to the side of the supporting plate 38 away from the resisting block 37 is a rubber block 36. One side of the rubber block 36 is arc-shaped. When processing the flange, place the flange on the workbench 1, and then rotate the nut 33. The nut 33 drives the pressing disc 32 and the screw rod 31 to rotate. Subsequently, the pressing disc 32 moves downward. The pressing disc 32 presses the resisting block 37. The resisting block 37 then displaces in the direction away from the screw rod 31. The stabilizing spring 35 deforms under force. Subsequently, the rubber block 36 presses the inner ring of the flange, and the flange is then firmly supported and lifted, and thus the flange can be processed. After the processing operation is completed, only need to rotate the nut 33 in the reverse direction. Subsequently, the pressing disc 32 loses the extrusion on the resisting block 37, and the stabilizing spring 35 pushes the resisting block 37, the supporting plate 38 and the rubber block 36 to reset.

[0024] In this embodiment: fixedly connected to one side of the resisting block 37 is a stabilizing spring 35. The stabilizing spring 35 is located in the positioning groove 34. The end of the stabilizing spring 35 away from the resisting block 37 is fixedly connected to the inner wall of the positioning groove 34, ensuring that the resisting block 37 resets after losing the extrusion of the extrusion block.

[0025] Specifically, the lower edge of the pressing disc 32 is chamfered. Fixedly connected to the upper surface of the pressing disc 32 is a nut 33, which is convenient for adjusting the position of the pressing disc 32.

[0026] Specifically, the number of both the positioning groove 34 and the resisting block 37 is three. The three positioning grooves 34 and the resisting blocks 37 are arranged in a circumferential array, which can stably position the flange.

[0027] Specifically, the auxiliary device 4 includes a support rod 44. The support rod 44 slides on the inner wall of the workbench 1. A cushion block 41 is fixedly connected to the upper end of the support rod 44, and a stabilizing frame 42 is fixedly connected to the lower end of the support rod 44. A sliding sleeve 46 is fixedly connected to the lower surface of the workbench 1. A control rod 45 is slidably connected to the inner wall of the sliding sleeve 46. One end of the control rod 45 is beveled. A pull ring 47 is fixedly connected to one end of the control rod 45. This solution can assist in discharging the flange, reduce the tight fit between the flange and the surface of the workbench 1, and prevent the situation where it is difficult for the user to remove it, ensuring the normal use of the equipment.

[0028] In this embodiment: A return spring 43 is fixedly connected to the upper surface of the stabilizing frame 42. The return spring 43 is sleeved on the support rod 44. The end of the return spring 43 away from the stabilizing frame 42 is fixedly connected to the lower surface of the workbench 1. Push the pull ring 47 in the direction close to the workbench 1. The pull ring 47 pushes the control rod 45 to displace. The control rod 45 pushes the stabilizing frame 42, the support rod 44, and the cushion block 41 upward. The return spring 43 deforms under force. The cushion block 41 then lifts the flange, and then the user can remove the flange. Then pull the pull ring 47 in the direction away from the workbench 1. The pull ring 47 drives the control rod 45 to reset, facilitating subsequent operations.

[0029] Working principle: When processing the flange, place the flange on the workbench 1, and then rotate the nut 33. The nut 33 drives the extrusion disc 32 and the screw rod 31 to rotate. Then the extrusion disc 32 moves downward. The extrusion disc 32 presses against the abutting block 37. The abutting block 37 then displaces in the direction away from the screw rod 31. The stabilizing spring 35 deforms under force. Then the rubber block 36 presses against the inner ring of the flange, and the flange is immediately fastened and lifted, and the flange can be processed. After the processing operation is completed, only rotate the nut 33 in the reverse direction. Then the extrusion disc 32 loses the extrusion on the abutting block 37. The stabilizing spring 35 pushes the abutting block 37, the support plate 38, and the rubber block 36 to reset. Then push the pull ring 47 in the direction close to the workbench 1. The pull ring 47 pushes the control rod 45 to displace. The control rod 45 pushes the stabilizing frame 42, the support rod 44, and the cushion block 41 upward. The return spring 43 deforms under force. The cushion block 41 then lifts the flange, and then the user can remove the flange. Then pull the pull ring 47 in the direction away from the workbench 1. The pull ring 47 drives the control rod 45 to reset, facilitating subsequent operations. This solution has a simple structure and low production cost. At the same time, this solution uses the rubber block 36 to contact the flange, effectively reducing the wear of the internal thread of the flange, reducing the economic loss of the producer, and can assist in discharging the flange, reducing the tight fit between the flange and the surface of the workbench 1, and preventing the situation where it is difficult for the user to remove it, ensuring the normal use of the equipment.
