Description

Technical Field

[0001] This utility model belongs to the field of deep groove ball bearing assembly technology, specifically a ball clamping tool for deep groove ball bearing assembly. Background Technology

[0002] Because deep groove ball bearings are designed with a filling angle, the outer race needs to be slightly deformed during assembly before the last steel ball can be installed. Currently, light-duty products can be assembled manually by deforming the bearing, while heavy-duty bearings require tooling to deform the bearing. Moreover, impact loads cannot be used for assembly, otherwise irreversible damage will be caused to the steel balls and raceways, resulting in scrap. This not only increases the operating cost but also results in a low assembly pass rate. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a ball clamping fixture for deep groove ball bearing assembly. It solves the problem that currently, light products can be assembled manually by deforming them, while heavy bearings require the use of fixtures to deform the bearings and cannot be assembled with impact loads, otherwise irreversible damage will be caused to the steel balls and raceways, resulting in scrap. This not only increases the working cost but also results in a low assembly qualification rate.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a deep groove ball bearing assembly clamping fixture, comprising a base, with a fixed seat one and a fixed seat two slidably mounted on both ends of the base, and a plurality of positioning grooves correspondingly opened on both ends of the base, on the fixed seat one and the fixed seat two, respectively. Two positioning pins are respectively installed in the positioning grooves opened on the fixed seat one and the fixed seat two. A support seat is fixedly mounted on the fixed seat two, and an inner cavity and a sliding groove are opened inside the support seat. A rotating shaft is installed in the inner cavity through a bearing, and one end of the rotating shaft passes through the support seat and is connected to a rotary shaft. A cam is installed on the rotating shaft, and a push rod two is slidably mounted in the sliding groove. A limit groove is opened at one end of the push rod two located in the inner cavity, and the cam is pressed against the push rod two through the limit groove.

[0005] As a further embodiment of this utility model: a pressure cap is provided on the outer wall of the support base, and one end of the rotating shaft passes through the support base and is locked by the pressure cap.

[0006] As a further embodiment of this utility model: a panel is fixedly installed on the base, and a top rod is fixedly installed on the fixing seat.

[0007] As a further embodiment of this utility model: one end of the rotary shaft is connected to a spinning arm, and the base has movable grooves at both ends.

[0008] As a further embodiment of this utility model: the bottom of the first fixed base and the second fixed base are equipped with movable blocks, the two movable blocks are slidably installed in the two movable slots respectively, and a push-pull rod is slidably installed through the base.

[0009] As a further embodiment of this utility model: one end of the push-pull rod passes through the base and is connected to the moving block, and the other end of the push-pull rod is equipped with a handle.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This deep groove ball bearing assembly clamping fixture, consisting of a push rod 1, a push rod 2, a rotary shaft, and a panel, allows for efficient operation. During operation, the ball bearing to be clamped is placed on the panel, and the positions of fixed seats 1 and 2 are adjusted. When push rod 1, mounted on fixed seat 1, presses against a point on the outer diameter of the ball to be clamped, the operator presses down the spinning arm. The spinning arm rotates, driving the rotary shaft, which in turn drives the rotating shaft. The rotating shaft, in turn, causes the cam mounted on it to rotate within a limiting groove. Because the cam is pressed against push rod 2, its rotation causes push rod 2 to move within a sliding groove until the end of push rod 2 presses against the symmetrical point between the ball bearing to be clamped and push rod 1. When the spinning arm is pressed down to a certain position, the outer ring of the ball bearing to be clamped undergoes a certain elastic deformation, allowing the steel ball to be installed. After installation, the spinning arm is raised, releasing the pressure applied to the outer diameter of the ball to be clamped by push rod 2, and the assembled bearing is removed. This process is repeated for the next set of bearings, reducing the negative impact of forceful assembly and improving the assembly pass rate.

[0012] 2. This deep groove ball bearing assembly clamping fixture, consisting of push-pull rods, a first fixed seat, moving blocks, and positioning pins, allows the operator to push two push-pull rods via handles during operation. These rods move two moving blocks within two moving slots, which in turn move the first and second fixed seats and their mounted components synchronously. Once in the desired position, the two positioning pins are fixed into the positioning slots on the first and second fixed seats and the base. This fixture can be adjusted to the appropriate position according to different product sizes, improving work efficiency. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a ball clamping fixture for a deep groove ball bearing assembly, including a base 1, a panel 2 fixedly installed on the base 1, and a top rod 8 fixedly installed on a fixed seat 3.

[0020] Fixed base 1 has a first fixed base 3 and a second fixed base 4 slidably mounted on both ends. Movable blocks 19 are mounted on the bottom of fixed base 1 and fixed base 2. The two movable blocks 19 are slidably mounted in the two movable slots 16 respectively. A push-pull rod 20 is slidably mounted through the base 1. One end of the push-pull rod 20 passes through the base 1 and is connected to the movable block 19. The other end of the push-pull rod 20 is equipped with a handle 21. Because of the push-pull rod 20, the operator pushes the two push-pull rods 20 through the handle 21. The two push-pull rods 20 drive the two movable blocks 19 to move in the two movable slots 16. The movement of the two movable blocks 19 drives the first fixed base 3, the second fixed base 4 and the components mounted on them to move synchronously, which facilitates subsequent work. It can be adjusted to the appropriate position according to different product sizes, thus improving work efficiency.

[0021] Several positioning slots 17 are provided on both ends of the base 1, on the first fixed seat 3 and the second fixed seat 4 respectively. Two positioning pins 18 are installed in the positioning slots 17 on the first fixed seat 3 and the second fixed seat 4 respectively. Because of the installation of positioning pins 18, the positioning pins 18 can prevent the first fixed seat 3 and the second fixed seat 4 from shifting during the operation, thus improving the stability of the operation.

[0022] A support base 5 is fixedly installed on the fixed base 2 4. A pressure cap 11 is provided on the outer wall of the support base 5. One end of the rotating shaft 14 passes through the support base 5 and is locked by the pressure cap 11.

[0023] The support base 5 has an inner cavity 10 and a sliding groove 12. A rotating shaft 14 is installed in the inner cavity 10 through a bearing. One end of the rotating shaft 14 passes through the support base 5 and is connected to a rotary shaft 7. One end of the rotary shaft 7 is connected to a spinning arm 6. The base 1 has moving grooves 16 at both ends. Because of the spinning arm 6, the physical strength of the assembly work can be saved and the workload of the workers can be reduced.

[0024] A cam 15 is installed on the rotating shaft 14. When the operator uses the spinning arm 6 to drive the rotating shaft 14 and the cam 15 installed on it to rotate, the cam 15 is close to the push rod 9. Therefore, the rotation of the cam 15 will drive the push rod 9 to move in the slide groove 12 until the end of the push rod 9 hits the symmetrical point between the ball bearing to be clamped and the push rod 8, until the outer ring of the ball bearing to be clamped is deformed, thereby installing the steel ball. This reduces the negative impact caused by violent assembly and improves the assembly qualification rate.

[0025] A push rod 9 is slidably installed in the slide groove 12. A limiting groove 13 is opened at one end of the push rod 9 located in the inner cavity 10. The cam 15 is close to the push rod 9 through the limiting groove 13.

[0026] The working principle of this utility model is as follows: During operation, the operator pushes the two push-pull rods 20 through the handle 21. The two push-pull rods 20 drive the two moving blocks 19 to move within the two moving slots 16. The movement of the two moving blocks 19 drives the fixed seat 3, the fixed seat 4, and the components mounted on them to move synchronously. When they reach the appropriate position, the two positioning pins 18 are fixed in the positioning slots 17 opened on the fixed seat 3, the fixed seat 4, and the base 1. When the top rod 8 installed on the fixed seat 3 presses against a point on the outer diameter of the ball to be clamped, the operator presses down the spinning arm 6. The spinning arm 6 rotates, driving the rotary shaft. 7 rotates, and the rotary shaft 7 drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 drives the cam 15 mounted on it to rotate in the limiting groove 13. Since the cam 15 is close to the push rod 9, the rotation of the cam 15 will drive the push rod 9 to move in the slide groove 12 until the end of the push rod 9 hits the symmetrical point of the ball bearing to be clamped and the push rod 8. When the spinning arm 6 is pressed down to a certain position, the outer ring of the ball bearing to be clamped will produce a certain elastic deformation, and the steel ball will be installed. After installation, the spinning arm 6 is lifted up, the pressure applied to the outer diameter of the ball to be clamped by the push rod 9 is released, the assembled bearing is taken out, and the above actions are repeated to process the next set of bearings.
