Description

Technical Field

[0001] This utility model belongs to the field of small rotor assembly technology, and more specifically, it relates to a small rotor assembly tooling. Background Technology

[0002] The rotor is a key component used for rotation in a mechanical system. It usually works with shafts, bearings, etc., and plays an important role in a variety of equipment. In short, the rotor is any component with rotational motion. It is the core component that converts power into rotational motion. When assembling small rotors, small rotor assembly fixtures are usually needed to press the bearings and rotor together.

[0003] Some small rotor assembly fixtures do not limit or fix the rotor during use, or only limit and fix one side of the rotor. However, during assembly, the operator manually places the rotor into the fixture. If the operator tilts or shifts the rotor during pressing, the rotor is prone to breakage when squeezed, which will affect the pressing effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a small rotor assembly tool to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a small rotor assembly fixture, which is achieved by the following specific technical means:

[0006] A small rotor assembly fixture includes a base, a pair of first guide rods mounted on the top of the base, a movable plate slidably mounted between the pair of first guide rods, a pressure plate mounted on the bottom of the movable plate, an mounting plate mounted on the top of the pair of first guide rods, a hydraulic rod mounted on the top of the mounting plate, and the output end of the hydraulic rod extending to the bottom of the mounting plate and connecting to the movable plate. A placement seat is mounted at the middle position of the top of the base, and the top of the placement seat has a placement groove. A pair of second guide rods are mounted on one side of the top of the base, and a fixing limiting plate slidably mounted between the pair of second guide rods. A pair of third guide rods are symmetrically installed at both ends of one side of the fixed limiting plate. A movable limiting plate is slidably installed between the pair of third guide rods. The fixed limiting plate and the movable limiting plate are symmetrically provided with a pair of limiting grooves on opposite sides. A first tension spring is installed on the side of each pair of third guide rods near the movable limiting plate, and the other end of the first tension spring is connected to the inside of the movable limiting plate. A first compression spring is fitted around the periphery of the second guide rod, and the two ends of the first compression spring are respectively connected to the bottom end of the fixed limiting plate and the top end of the base. An ejection assembly is installed inside the base.

[0007] Furthermore, a second compression spring is fitted around the periphery of the first guide rod, and the two ends of the second compression spring are respectively connected to the top end of the base and the bottom end of the movable plate.

[0008] Furthermore, lower positioning rods are installed at the four corners of the top of the base.

[0009] Furthermore, upper positioning rods are installed at the four corners of the bottom of the movable plate at positions that match the lower positioning rods, and the upper positioning rods match the lower positioning rods.

[0010] Furthermore, the ejector assembly includes a mounting groove, which is installed at the top of the base below the placement seat and communicates with the placement groove. An ejector plate is slidably installed in the mounting groove. A plurality of second tension springs are installed at the bottom end of the ejector plate, and the other end of the second tension springs is connected to the bottom end of the mounting groove. A cam is rotatably installed in the mounting groove at a position below the ejector plate via a bearing seat, and the cam is in close contact with the ejector plate.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a small rotor assembly fixture, including a base 1. A pair of first guide rods 2 are mounted on the top of the base 1. A movable plate 3 is slidably mounted between the pair of first guide rods 2. The movable plate 3 can move up and down along the first guide rods 2. A pressure plate 4 is mounted on the bottom of the movable plate 3. The size of the pressure plate 4 matches the size of the rotor, and the pressure plate 4 extends to two sections on both sides for pushing the movable limiting plate 12 and the fixed limiting plate 10 downward. An mounting plate 5 is mounted on the top of the pair of first guide rods 2. A hydraulic rod 6 is mounted on the top of the mounting plate 5, and the output end of the hydraulic rod 6 extends to the bottom of the mounting plate 5 and connects to the movable plate 3. A placement seat 7 is mounted at the middle position of the top of the base 1. The top of the placement seat 7 is provided with a placement groove 8. Both the placement seat 7 and the placement groove 8 are circular. The size of the placement groove 8 matches the size of the bearing. A pair of second guide rods 9 are mounted on one side of the top of the base 1. A fixed limiting plate 10 is slidably installed between the second guide rods 9. The fixed limiting plate 10 can move up and down between the second guide rods 9. A pair of third guide rods 11 are symmetrically installed at both ends of one side of the fixed limiting plate 10. A movable limiting plate 12 is slidably installed between the pair of third guide rods 11. The movable limiting plate 12 can move along the third guide rods 11. A pair of limiting grooves 13 are symmetrically provided on opposite sides of the fixed limiting plate 10 and the movable limiting plate 12. The size of the pair of limiting grooves 13 matches the size of the rotor to limit the rotor. A first tension spring 14 is installed on the side of the pair of third guide rods 11 near the movable limiting plate 12. The other end of the first tension spring 14 is connected to the inside of the movable limiting plate 12. A first compression spring 15 is fitted around the second guide rod 9. The two ends of the first compression spring 15 are connected to the bottom end of the fixed limiting plate 10 and the top end of the base 1, respectively. An ejection assembly is installed inside the base 1.

[0027] The first guide rod 2 is fitted with a second compression spring 16 around its periphery, and the two ends of the second compression spring 16 are respectively connected to the top end of the base 1 and the bottom end of the movable plate 3.

[0028] The base 1 has a lower positioning rod 17 installed at the four corners of its top end, and the top of the lower positioning rod 17 is provided with a positioning groove for positioning.

[0029] Among them, upper positioning rods 18 are installed at the four corners of the bottom of the movable plate 3 at positions that match the lower positioning rods 17, and the upper positioning rods 18 match the lower positioning rods 17.

[0030] As the upper positioning rod 18 moves downward, it enters the positioning groove at the top of the lower positioning rod 17, thereby positioning the moving plate 3.

[0031] The ejector assembly includes a mounting groove 19, which is installed at the top of the base 1 below the placement seat 7 and is connected to the placement groove 8. The diameter of the mounting groove 19 is smaller than the diameter of the placement groove 8 to prevent the bearing from falling into the interior of the placement groove 8. An ejector plate 20 is slidably installed in the mounting groove 19 and can slide from the mounting groove 19 into the placement groove 8. Several second tension springs 21 are installed at the bottom of the ejector plate 20, and the other end of the second tension springs 21 is connected to the bottom of the mounting groove 19 to pull the ejector plate 20 to reset. A cam 22 is rotatably installed in the mounting groove 19 below the ejector plate 20 via a bearing seat and is in close contact with the ejector plate 20.

[0032] When the protruding end of the cam 22 rotates to a position where it is in contact with the bottom end of the ejector plate 20, the ejector plate 20 moves upward and into the placement groove 8, ejecting the bearing.

[0033] A knob 23 is installed on one side of the base 1, and one end of the knob 23 extends into the mounting groove 19 and is connected to the cam 22 to control the rotation of the cam 22.

[0034] An anti-slip pad can be added to one side of the knob 23 to increase the damping between it and the base 1 and improve stability.

[0035] The working principle of this embodiment is as follows: When using this small rotor assembly fixture, the operator first uploads the extension length data of the hydraulic rod 6 to the hydraulic control system. After adjustment, the operator places the bearing in the placement groove 8, then pulls the movable limiting plate 12 and places the rotor in a pair of limiting grooves 13, inserting the bottom end of the rotor into the bearing. After insertion, the operator releases the movable limiting plate 12. Under the action of the first tension spring 14, the movable limiting plate 12 re-fits with the fixed limiting plate 10, thereby fixing the rotor through the limiting grooves 13. After fixing, the operator controls the hydraulic rod 6 to extend, causing the pressure plate 4 to move downward and press the rotor and bearing together. After pressing, the hydraulic rod 6 retracts. At this time, the operator pulls the movable limiting plate 12 and removes the rotor. During the assembly process, if the bearing fails to be installed successfully, the operator can rotate the knob 23. The knob 23 drives the cam 22 to rotate, causing the ejector plate 20 to move upward and push out the bearing.
