Description

Technical Field

[0001] The utility model relates to the technical field of bearing fixtures, in particular to a fixture for machining automobile bearings. Background Technique

[0002] A bearing seat fixture is a production tool specifically used to ensure the quality of bearing seat products, which can make the production process of bearing seats more convenient. Different bearing seat fixtures will vary according to their different structures, forms, working conditions, and design principles. Therefore, the types and styles of bearing seat fixtures are diverse, accounting for a large proportion both in terms of quantity and style.

[0003] Currently, the fixtures used for bearing machining usually use a circular cone to expand and support the inner ring of the bearing to play a role in clamping and supporting. Although the fixing effect of such fixtures is good, when multiple bearings need to be continuously machined, it is inconvenient to disassemble and move the bearings, resulting in low efficiency when multiple bearings are machined simultaneously. Therefore, a fixture for machining automobile bearings is proposed to solve the above problems. Content of the Utility Model

[0004] To solve the technical problems in the background technique, the utility model proposes a fixture for machining automobile bearings, which has good clamping effect, continuous machining of multiple bearings, convenient movement of bearings, and improved bearing machining efficiency.

[0005] The utility model provides a fixture for machining automobile bearings, including a support table. Both long edges of the support table are fixedly provided with flank support plates. A left bottom plate is connected between the left sides of the two flank support plates, and a right L-shaped plate is connected between the right sides of the two flank support plates. Multiple groups of clamping plates are arranged on the top of the support table. Multiple groups of limiting holes are opened on the top of the support table. Bearings are arranged between multiple groups of clamping plates. Multiple bidirectional threaded rods are further arranged between the two flank support plates. Worms are arranged in the middle of multiple bidirectional threaded rods. A motor is arranged on the top of the left bottom plate. The right L-shaped plate and the left bottom plate are rotatably connected by a bearing with a worm, and one end of the worm is connected to the motor. Two sliding blocks are further arranged on the outer surfaces of multiple bidirectional threaded rods. The tops of multiple sliding blocks penetrate through multiple groups of limiting holes and are fixedly connected to the bottoms of multiple groups of clamping plates.

[0006] Preferably, a V-shaped groove is opened on one side surface of each group of clamping plates facing each other. The V-shaped groove opened in each group of clamping plates can clamp the bearing between the two clamping plates for fixation.

[0007] Preferably, fixing parts are fixedly installed at the four corners of the two flank support plates.

[0008] Preferably, the threads of the bidirectional threaded rod are divided into two ends, and the turning directions of the threads at both ends are opposite.

[0009] Preferably, a threaded through-hole for the bidirectional threaded rod to pass through is provided on the sliding block, and the threaded through-hole is threadedly connected to the bidirectional threaded rod. The sliding block is composed of a T-shaped block at the bottom and two sliding thin plates at the top. The two sliding thin plates of the sliding block penetrate each group of limiting holes and are fixedly connected to the clamping plate.

[0010] Compared with the prior art, the above technical solution of the present utility model has the following beneficial technical effects:

[0011] The automobile bearing processing fixture realizes the clamping and fixing of multiple bearings simultaneously through multiple groups of clamping plates, and realizes a stable fixing effect through the V-shaped grooves of multiple groups of clamping plates. At the same time, the Geneva mechanism is used to drive the movement of the bearings between multiple clamping plates, so as to conveniently move the bearings and improve the bearing processing efficiency.

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the drawings. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.

[0018] In the description of the utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] In the description of the utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, such as welding, riveting, bonding, etc., or a detachable connection, such as threaded connection, key connection, pin connection, etc., or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0020] As Figures 1-4 shown, a car bearing processing fixture proposed by the present utility model includes a support table 1. Flanking support plates 11 are fixed to the edges of the two longer sides of the support table 1. A left bottom plate 3 is connected between the left sides of the two flanking support plates 11. A right L-shaped plate 4 is connected between the right sides of the two flanking support plates 11. A plurality of clamping plates 8 are arranged on the top of the support table 1. A plurality of limiting holes 13 are formed in the top of the support table 1. Bearings 2 are arranged between the plurality of clamping plates 8. A plurality of bidirectional threaded rods 5 are further arranged between the two flanking support plates 11. Worms 7 are arranged in the middle of the plurality of bidirectional threaded rods 5. A motor 9 is arranged on the top of the left bottom plate 3. The right L-shaped plate 4 and the left bottom plate 3 are rotatably connected by a bearing with a worm 6, and one end of the worm 6 is connected to the motor 9. Two sliding blocks 12 are further arranged on the outer surfaces of the plurality of bidirectional threaded rods 5. The tops of the plurality of sliding blocks 12 penetrate through the plurality of limiting holes 13 and are fixedly connected to the bottoms of the plurality of clamping plates 8.

[0021] It should be noted that a strip-shaped hole is formed in the middle of the support table 1. A moving device for driving the plurality of bearings 2 to translate at equal intervals is arranged at the bottom of the strip-shaped hole to realize the continuity during the processing of the plurality of bearings 2. The moving device can refer to the Geneva mechanical structure to realize the translation of the bearings 2. The Geneva structure is a known public technology in the prior art and will not be further elaborated in detail herein.

[0022] In an alternative embodiment, a V-shaped groove is formed on each opposite side surface of the multiple sets of clamping plates 8. The V-shaped groove formed in each set of clamping plates 8 can clamp the bearing 2 between the two clamping plates 8 for fixation, and the V-shaped groove between the two clamping plates 8 can effectively limit the position of the bearing 2.

[0023] It should be noted that a protective layer can be added to the surface of the V-shaped groove between each set of clamping plates 8 to protect the surface of the bearing 2 from damage.

[0024] In an alternative embodiment, fixing members 10 are fixedly installed at the four corners of the two wing support plates 11. The fixing members 10 are used for fixing on the bearing processing tabletop.

[0025] In an alternative embodiment, the threads of the bidirectional threaded rod 5 are divided into two ends, and the turning directions of the threads at both ends are opposite, which can make the two sliding blocks 12 on the bidirectional threaded rod 5 move relative to each other.

[0026] In an alternative embodiment, a threaded through hole through which the bidirectional threaded rod 5 can pass is formed in the sliding block 12, and the threaded through hole is threadedly connected to the bidirectional threaded rod 5. The sliding block 12 is composed of a T-shaped block at the bottom and two sliding thin plates at the top. The two sliding thin plates of the sliding block 12 penetrate through each set of limiting holes 13 and are fixedly connected to the clamping plates 8.

[0027] It should be noted that the two sliding thin plates on the sliding block 12 are slidably arranged in each set of limiting holes 13.

[0028] Specifically, when it is necessary to use the fixture to fix the bearing 2, the motor 9 can be driven to rotate the worm 6, so that the worm 6 drives multiple worm wheels 7 to rotate, and further makes the bidirectional threaded rod 5 fixed to the worm wheel 7 rotate. Also, since multiple sets of sliding blocks 12 are threadedly connected to the bidirectional threaded rod 5, multiple sets of sliding blocks 12 drive the clamping plates 8 to move relatively in the limiting holes 13. When each set of clamping plates 8 moves relatively, the bearing 2 is limited and fixed through the V-shaped groove between the two clamping plates 8, so as to achieve the clamping effect.

[0029] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples falling within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
