Description

Technical Field

[0001] The present application relates to the technical field of machine tool processing of thin-walled cylinder products, and in particular to an internal support clamping tool for processing thin-walled cylinders. Background Art

[0002] When designing and manufacturing power switches and transmission housings, in order to meet the requirements of electrical performance, mechanical strength, installation convenience and other aspects, thin-walled cylindrical structures are usually adopted. In the power system, power switches and transmission housings often need to be connected to other equipment or pipelines, so it is necessary to process flange surfaces on the cylinder so that these components can be connected through flanges to ensure the stability and sealing of the connection.

[0003] The flange surfaces on the power switch and the power transmission shell are usually processed by a lathe. The lathe includes a lathe bed, a headstock, and a tailstock. The headstock is fixed to the lathe bed, and the tailstock is slidably arranged on the lathe bed. The tailstock slides along the length direction of the lathe bed, so that the lathe can adapt to cylindrical workpieces of different lengths. The headstock and the tailstock are both provided with a main shaft for fixing the supporting structure. In the prior art, the supporting structure includes four screws threadedly connected to the fixed shaft. The four screws are arranged in a circular array with the axis of the fixed shaft as the center, and an arc block consistent with the inner wall circle of the cylinder is provided on the screw head.

[0004] However, in actual use, it was found that this clamping method, on the one hand, requires manual use of a wrench to rotate the screw until the arc block is tightly against the inner wall of the cylinder, and the cylinder clamping and adjustment time is long and the efficiency is low. On the other hand, the manual adjustment method cannot ensure that the supporting force of the four arc blocks on the inner wall of the cylinder is consistent. After the processing is completed, when the supporting tooling is loosened to measure the product size, the flange outer circle and the sealing groove are prone to out-of-round size deviations.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Embodiment 1, Embodiment 1 of the present application discloses an internal support clamping tool for processing thin-walled cylinders, referring to Figure 1 and Figure 2 , including a support block 1, on which a plurality of control blocks 2 are slidably connected, and the plurality of control blocks 2 are arranged in a circular array with the axis of the support block 1 as the center. In the embodiment of the present application, there are four control blocks 2, and the control block 2 slides radially along the support block 1, so that a control slide groove 21 for sliding the control block 2 is provided on the support block 1, and one end of the control block 2 located at the control slide groove 21 is arranged in a dovetail shape, and the shape of the control slide groove 21 is adapted to the control block 2. Through the dovetail arrangement of the control block 2, on the one hand, the stability of the control block 2 sliding on the support block 1 is improved, and on the other hand, the control block 2 is restricted from moving in a direction away from the support block 1, thereby improving the stability of the control block 2 sliding on the support block 1.

[0034] Reference Figure 1 and Figure 2A contact block 22 is fixedly provided on the side of the control block 2 away from the control sliding block 3. The side of the contact block 22 away from the control block 2 is arranged in an arc shape, so that the contact block 22 and the control block 2 are detachably connected. The arc-shaped adapted contact block 22 can be replaced according to the inner diameter of the cylinder to be supported, which effectively increases the contact area between the contact block 22 and the inner wall of the cylinder, and improves the effect of providing support to the cylinder through the contact block 22, and the cylinder is not easily deformed during the support process. The abutment block 22 is fixed to the control block 2 by two control bolts 221, and the two control bolts 221 are symmetrically arranged on both sides of the center line of the abutment block 22, thereby improving the stability of the abutment block 22 fixed on the control block 2, and the abutment block 22 is provided with a control countersunk hole 222 for accommodating the screw head of the control bolt 221 and a control through hole 223 for the control bolt 221 to pass through, the control countersunk hole 222 is connected with the control through hole 223, and the support block 1 is provided with a control threaded hole 224 that is threadedly matched with the control bolt 221. The abutment block 22 and the control block 2 are fixed by the control bolt 221, so that the connection strength between the abutment block 22 and the control block 2 is high and the installation is convenient, so that it is convenient to replace the matching abutment block 22 according to the size of the cylinder.

[0035] Reference Figure 1 and Figure 2 The control block 2 is fixedly connected with a limiting plate 23, and a limiting groove 231 for accommodating the limiting plate 23 is provided on the control block 2, and an engaging groove 225 for engaging the limiting plate 23 is provided on the abutting block 22. When the abutting block 22 is fixed to the control block 2, one end of the limiting plate 23 is located in the limiting groove 231, and the other end of the limiting plate 23 is located in the engaging groove 225. The limiting plate 23 and the control block 2 are fixed by a limiting bolt 232. The limiting plate 23 cooperates with the engaging groove 225 to provide positioning for the installation of the abutting block 22, so that the abutting block 22 is convenient to move to the control through hole 223 and communicate with the control threaded hole 224, thereby improving the disassembly and assembly efficiency of the abutting block 22. The two ends of the limiting plate 23 are arranged in an arc shape, so that the limiting plate 23 can slide into the engaging groove 225, which further improves the installation efficiency of the abutting block 22.

[0036] A friction-increasing pad is provided at one end of the abutment block 22 that is away from the control block 2. The friction-increasing pad is supported by rubber material. Through the setting of the friction-increasing pad, the friction between the abutment block 22 and the inner wall of the cylinder is effectively increased, and the effect of supporting the cylinder through the abutment block 22 is improved, and the cylinder is not easy to rotate relative to the support block 1; the rubber setting can also provide a certain buffering force, so that the abutment block 22 is not easy to cause damage to the inner wall of the cylinder, thereby improving the supporting effect of the abutment block 22 on the inner wall of the cylinder.

[0037] Reference Figure 1 and Figure 2A control slider 3 for controlling the sliding movement of the control block 2 is slidably connected to the support block 1. The control slider 3 is coaxially arranged with the support block 1. The control slider 3 slides along the axial direction of the support block 1. The control block 2 and the control slider 3 are matched with an oblique wedge. The control slider 3 is set with a square inclined surface. In the embodiment of the present application, the angle between the inclined surface of the control slider 3 and the axis of the control slider 3 is 10 degrees. Through the design of the oblique wedge cooperation between the control block 2 and the control slider 3, when the control slider 3 slides along the axial direction of the support block 1, the four control blocks 2 located on the support block 1 can synchronously slide along the radial direction of the support block 1, and the sliding lengths of the four control blocks 2 are consistent, so that the supporting force and position size of the abutment block 22 on the inner wall of the cylinder are consistent, thereby improving the quality of support provided to the cylinder.

[0038] Reference Figure 1 and Figure 2 The support block 1 is provided with a control slide member for controlling the sliding movement of the control slide block 3. The control slide member is a control oil cylinder 4. The control oil cylinder 4 includes a housing 41 and a piston rod 42. The piston rod 42 is slidably arranged in the housing 41. One end of the housing 41 is in contact with the end face of the support block 1 away from the control block 2. The support block 1 and the housing 41 are fixed by fixing bolts 43. There are four fixing bolts 43. The four fixing bolts 43 are arranged in a circular array with the axis of the support block 1 as the center. The four fixing bolts 43 are staggered with the control block 2. A control flange 44 is provided at the other end of the housing 41. The control flange 44 is used to enable the control oil cylinder 4 to be fixed to the fixed shafts on the head and foot of the milling machine. The fixed shaft is rotatably arranged on the milling machine, so that the control oil cylinder 4 can be driven to rotate according to the rotation of the fixed shaft, and then the cylinder body can be driven to rotate, which is convenient for machining the flange surface on the cylinder body.

[0039] Reference Figure 2 The piston rod 42 is coaxially fixed with the control slide block 3. When the control slide block 3 slides under the action of the control cylinder 4, it can drive the control block 2 to slide along the control slide groove 21, effectively improving the speed and efficiency of providing support to the inner wall of the cylinder through the internal support clamping tooling, and the magnitude of the force providing support to the inner wall of the cylinder can be adjusted by the pressure of the control cylinder 4, so that the internal support clamping tooling can adapt to cylinders of different diameters and wall thicknesses. The whole set of tooling is simple to operate, safe and reliable, and solves the problem of elastic deformation of thin-walled cylinders during clamping. Reference Figure 1 and Figure 2The support block 1 is coaxially provided with a limit tube 11, and the support block 1 is provided with a limit cavity 111 for the limit tube 11 to be engaged. The limit tube 11 is coaxially fixed with a limit baffle 112 at one end away from the control slider 3. The limit baffle 112 is in contact with both the support block 1 and the control block 2. When the control slider 3 slides to be in contact with the limit tube 11, the sliding distance of the control block 2 is the largest. The setting of the limit baffle 112 can, on the one hand, limit the shaking of the control block 2 in the direction away from the support block 1, and on the other hand, can provide protection for the control chute 21, so that foreign impurities or dust are not easy to move into the control chute 21, thereby ensuring the stability and reliability of the sliding of the control block 2; the setting of the limit tube 11 can effectively limit the maximum sliding distance of the control slider 3, thereby ensuring the service life of the internal support clamping tooling. The limit baffle 112 is fixed to the support block 1 by a connecting bolt 113.

[0040] Reference Figure 2 A positioning rod 12 corresponding to the control block 2 is fixed on the support block 1. The positioning rod 12 is threadedly fixed to the control block 2. One end of the positioning rod 12 is in contact with the housing 41 of the control cylinder 4. The other end of the positioning rod 12 passes through the support block 1 and extends into the control slide groove 21. A positioning slide groove 121 for the positioning rod 12 to slide is provided on the control block 2. With the cooperation of the positioning rod 12 and the positioning slide groove 121, the sliding length of the control block 2 is further limited, thereby ensuring the service life of the internal support clamping tooling.

[0041] Embodiment 2 is different from Embodiment 1 in that, referring to Figure 3 and Figure 4 , a control member for judging the sliding length of the control block 2 is provided on the support block 1, and the control member includes a partition block 5 slidably arranged on the support block 1, and the partition block 5 is arranged corresponding to the control block 2. A partition slide groove 51 for the partition block 5 to slide is opened through the support block 1, and a partition embedding groove 52 for the partition block 5 to be embedded after sliding is provided on the control block 2. When the sliding distance of the control block 2 is the smallest, the partition embedding groove 52 is connected with the partition slide groove 51, and a partition elastic member for pushing the partition block 5 to slide toward the partition embedding groove 52 is provided on the support block 1. In the embodiment of the present application, the partition elastic member is a partition spring 53, one end of the partition spring 53 is fixed to the support block 1, and the other end of the partition spring 53 is fixed to the partition block 5. The partition block 5 can slide down to be embedded in the partition embedding groove 52 under the action of the partition spring 53.

[0042] Reference Figure 3 and Figure 4The partition block 5 is provided with a partition slope 54 on the side facing the control slider 3. When one end of the partition block 5 provided with the partition slope 54 is embedded in the partition embedding groove 52 under the action of the partition spring 53, the other end of the partition block 5 is completely received in the partition slide groove 51. When the control block 2 slides in the direction away from the axis of the control slider 3, the partition block 5 slides in the direction away from the control block 2 under the cooperation of the partition slope 54 and the inner wall of the partition embedding groove 52. Then, the end of the partition block 5 not provided with the partition slope 54 slides to the outside of the partition slide groove 51, so that the end of the partition block 5 away from the partition slope 54 includes a plurality of reflective blocks 55 of different colors. The number of reflective blocks 55 depends on the sliding length of the partition block 5. When the sliding distance of the control block 2 is the longest, all the partition blocks 5 are located outside the partition slide groove 51.

[0043] Reference Figure 3 and Figure 4 The reflective block 55 is made of resin material, and the dye used to dye the reflective block 55 has a certain fluorescent effect. A reflector 56 cooperating with the reflective block 55 is provided at one end of the support block 1 away from the control block 2. In actual use, the operator can shine a light from the opening of the cylinder toward the partition block 5. The operator can judge the sliding distance of the control block 2 according to the color feedback on the reflector 56, so as to facilitate the judgment of whether the sliding distances of the four control blocks 2 are consistent, and can effectively test the service life of the internal support clamping tooling.

[0044] Reference Figure 3 and Figure 4 The support block 1 is also slidably connected with a locking block 6. The support block 1 is provided with a locking groove 61 for the locking block 6 to slide. The control block 2 is provided with a locking groove 62 for the locking block 6 to slide and embed. When the sliding distance of the control block 2 is the largest, the locking groove 61 is connected with the locking groove 62. The locking block 6 cooperates with the locking groove 62 to limit the sliding of the control block 2 in the direction away from the axis of the control slide block 3, further limiting the sliding length of the control block 2 and ensuring the service life of the internal support clamping tooling. A control gear 63 is provided between the locking block 6 and the partition block 5. The control gear 63 is rotatably connected to the support block 1. The locking block 6 and the partition block 5 are both provided with a control rack meshing with the control gear 63. When the partition block 5 slides in the direction away from the control block 2 under the action of the control block 2, the locking block 6 can slide in the direction of the control block 2 under the action of the gear transmission. No additional driving source is required, which is convenient for controlling the sliding length and timing of the locking block 6.

[0045] Reference Figure 3 and Figure 4A locking inclined surface 64 is provided on the side of the locking block 6 facing away from the partition block 5. When the control block 2 slides toward the axis of the control slide block 3, the locking block 6 slides in the direction away from the control block 2 under the cooperation of the locking inclined surface 64 and the inner wall of the locking groove 62. Through the setting of the locking inclined surface 64, the locking block 6 is not easy to affect the sliding of the control block 2 toward the axis of the control slide block 3, which facilitates to release the locking of the control block 2 by the locking block 6 to a certain extent.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
