Description

Technical Field

[0001] This utility model relates to the field of fixture and tooling technology, and in particular to an auxiliary tooling for thin-walled rotating parts. Background Technology

[0002] Imagine two points at the two ends of an object, and a line connecting the two points passes through the object. The object rotates around this line as its center. When rotating, each part of the object has the same shape when it reaches a fixed position. This is a standard solid of revolution. Common circular tubes and cylinders are solid of revolution structures. When processing such thin-walled solids of revolution, appropriate fixtures are needed for clamping.

[0003] Existing auxiliary tooling for thin-walled rotary parts mostly uses a three-jaw chuck to automatically clamp the parts. However, this method is prone to problems during clamping, as the clamping blocks may not simultaneously contact the outer or inner wall of the part if it is not positioned correctly. This can easily cause the part to deform, affecting its subsequent use and resulting in poor clamping performance. Therefore, there is an urgent need for an auxiliary tooling for thin-walled rotary parts to solve these problems. Utility Model Content

[0004] The main purpose of this utility model is to provide an auxiliary tooling for thin-walled rotating parts.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] An auxiliary tooling for a thin-walled rotating part includes a base. The upper end of the base has a set of cross-shaped cavities. A gearbox is installed at the center of each cavity. A main gear is located on one side of the gearbox. A bidirectional screw is installed inside the main gear. One end of the bidirectional screw is connected to a drive motor. Secondary gears are connected to both sides of the main gear. A stud is fixed to each of the secondary gears. A screw block is fitted onto each stud and the bidirectional screw. A limit groove is fixed to the top of each screw block. A locking plate is installed in the limit groove. A drive box is fixed to the inner wall of the limit groove. Two sets of electric push rods are symmetrically installed inside the drive box.

[0007] Preferably, the cavity is formed on the base, the bidirectional screw is rotatably installed in the cavity, and the output shaft of the drive motor is fixedly connected to one end of the bidirectional screw.

[0008] Preferably, the bidirectional screw passes through the gearbox, the main gear is fixed on the bidirectional screw, the auxiliary gear meshes with the main gear, and both the auxiliary gear and the main gear are bevel gears.

[0009] Preferably, one end of the stud is fixedly connected to the secondary gear, and the other end of the stud is rotatably connected to the cavity.

[0010] Preferably, the screw block, the stud, and the bidirectional screw are all connected by threads, the screw block matches the specifications of the cavity, the limiting groove is fixed to the screw block by screws, and the limiting groove has an arc-shaped structure.

[0011] Preferably, the drive box is formed on the limiting groove, and the fixing part of the electric push rod is connected to the inner wall of the drive box by screws.

[0012] Preferably, the output end of the electric push rod is connected to the locking plate by screws, and the locking plate and the limiting groove have the same curvature.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] In the process of clamping thin-walled rotating parts, this utility model can drive a bidirectional screw to rotate according to the diameter of the part. This causes the main gear to drive two sets of studs to rotate through the secondary gear. The four sets of studs can move synchronously to adjust the position of the limiting groove to match the diameter of the part. Then, the part is placed in the limiting groove and positioned using the limiting groove. Then, the locking plate moves under the action of the electric push rod to automatically clamp the part. This allows the locking plate to be positioned before clamping, effectively preventing the part from deforming and improving the clamping effect of the device. Attached Figure Description

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-4 As shown, this embodiment provides an auxiliary tooling for a thin-walled rotating part, including a base 2. The upper end of the base 2 has a set of cross-shaped cavities 3. A gearbox 1 is installed at the center of the cavity 3. A main gear 11 is provided on one side of the gearbox 1. A bidirectional screw 7 is installed in the main gear 11. One end of the bidirectional screw 7 is connected to a drive motor 5. A secondary gear 12 is connected to both sides of the main gear 11. A stud 9 is fixed on the secondary gear 12. A screw block 8 is sleeved on both the stud 9 and the bidirectional screw 7. A limit groove 4 is fixed at the top of the screw block 8. A locking plate 10 is installed in the limit groove 4. A drive box 6 is fixed on the inner wall of the limit groove 4. Two sets of electric push rods 13 are symmetrically installed in the drive box 6.

[0023] The cavity 3 is formed on the base 2, and the bidirectional screw 7 is rotatably installed in the cavity 3. The output shaft of the drive motor 5 is fixedly connected to one end of the bidirectional screw 7, and the drive motor 5 drives the bidirectional screw 7 to rotate.

[0024] The bidirectional screw 7 passes through the gearbox 1. The main gear 11 is fixed on the bidirectional screw 7. The auxiliary gear 12 meshes with the main gear 11. Both the auxiliary gear 12 and the main gear 11 are bevel gears. The bidirectional screw 7 drives the auxiliary gear 12 to rotate through the main gear 11.

[0025] One end of the stud 9 is fixedly connected to the auxiliary gear 12, and the other end of the stud 9 is rotatably connected to the cavity 3. The auxiliary gear 12 drives the stud 9 to rotate.

[0026] The screw block 8, stud 9, and double-acting screw 7 are all connected by threads. The screw block 8 matches the specifications of the cavity 3. The limiting groove 4 is fixed to the screw block 8 by screws. The limiting groove 4 has an arc-shaped structure. During the rotation of the stud 9 and double-acting screw 7, the screw block 8 can move synchronously under the action of the threads, thereby adjusting the position of the limiting groove 4 to match the outer diameter of the part.

[0027] The drive box 6 is formed on the limiting groove 4. The fixing part of the electric push rod 13 is connected to the inner wall of the drive box 6 by screws. The drive box 6 provides an installation position for the electric push rod 13, and the electric push rod 13 can drive the locking plate 10 to move.

[0028] The output end of the electric push rod 13 is connected to the locking plate 10 by screws. The locking plate 10 and the limiting groove 4 have the same curvature. The electric push rod 13 can lock the part in the limiting groove 4 by pushing the locking plate 10.

[0029] The working principle of this device is as follows: The base 2 is installed and fixed and connected to an external electrical control mechanism. During the clamping process of thin-walled rotating parts, the bidirectional screw 7 is driven by the drive motor 5 to rotate according to the diameter of the part. This causes the main gear 11 to drive the two sets of studs 9 to rotate through the secondary gear 12. This allows the four sets of screw blocks 8 to move synchronously and adjust the position of the limiting groove 4 to match the diameter of the part. Then, the part is placed in the limiting groove 4 and positioned using the limiting groove 4. Then, the locking plate 10 moves under the action of the electric push rod 13 to automatically clamp the part. This allows the locking plate 10 to be positioned before clamping, effectively preventing the part from deforming and improving the clamping effect of the device.
