Description

Technical Field

[0001] The utility model relates to the technical field of copper alloy bearings, and particularly relates to a clamping jig for processing copper alloy bearings. Background Technique

[0002] Bearings are important components in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. According to the different friction properties of the moving elements, bearings can be divided into two major categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibration and noise are larger, and the price is also higher. A rolling bearing generally consists of four parts: an outer ring, an inner ring, rolling elements and a cage. According to the shape of the rolling elements, rolling bearings are divided into two major categories: ball bearings and roller bearings.

[0003] However, the existing clamping jigs for processing copper alloy bearings have the following problems in the process of use: when the traditional copper alloy bearings are drilled, different diameters are required for clamping copper alloy bearings of different diameters, resulting in low practicability and inability to meet the diversified market demands. In addition, for clamping copper alloy bearings of different shapes, different-shaped clamping frames are required, which increases the production cost and is very inconvenient to adjust. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clamping jig for processing copper alloy bearings to solve the related problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A clamping jig for processing copper alloy bearings, including a processing base, a fixed housing and a motor. The top of the processing base is provided with a fixed housing, and a motor is arranged inside the fixed housing. The output end of a cylinder is installed at the top of the processing base and is provided with a fixed block. The output ends of the fixed block and the motor are both provided with fixed shafts through bearings, and a conical positioning block is arranged on the outer wall of the fixed shaft. A rubber block is arranged on the outer wall of the conical positioning block, and a copper alloy bearing workpiece is arranged between the outer walls of the rubber blocks. An installation mechanism for fixing the position of the conical positioning block is installed on one side of the fixed shaft.

[0006] The clamping jig for processing copper alloy bearings provided by this technical solution, the installation mechanism includes a cross-shaped positioning groove and a cross-shaped positioning block. A cross-shaped positioning groove is opened on the inner wall of the conical positioning block, and a cross-shaped positioning block is installed on one side of the fixed shaft, and the outer wall of the cross-shaped positioning block is in contact with the inner wall of the cross-shaped positioning groove.

[0007] A clamping fixture for processing copper alloy bearings provided by this technical solution, threaded grooves penetrating through a cross-shaped positioning groove are provided at both ends of the conical positioning block, and a positioning screw is arranged inside the threaded grooves, and the outer wall of the positioning screw meshes with the inner wall of the threaded groove.

[0008] A clamping fixture for processing copper alloy bearings provided by this technical solution, anti-slip threads are arranged on the outer wall of the positioning screw.

[0009] A clamping fixture for processing copper alloy bearings provided by this technical solution, the output end of the motor is connected to one side of the fixed shaft through a coupling.

[0010] Compared with the prior art, the present utility model provides a clamping fixture for processing copper alloy bearings, which has the following beneficial effects:

[0011] 1. By starting the cylinder to push the conical positioning block at the position of the fixed block into the outer wall of the copper alloy bearing workpiece, since the shapes of the two conical positioning blocks can fix copper alloy bearing workpieces of different diameters, the clamping range is improved and the practicability is increased.

[0012] 2. The fixed shaft drives the cross-shaped positioning block to insert into the inner wall of the cross-shaped positioning groove, and then the positioning screw is rotated to mesh with the inner wall of the threaded groove, so that the position between the positioning screw and the conical positioning block is fixed. This structure facilitates the fixation between the conical positioning block and the fixed shaft, and facilitates the replacement of the conical positioning block for clamping copper alloy bearings of different shapes.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1, as Figure 1-2 shown, the present invention provides a technical solution: a clamping fixture for processing copper alloy bearings, including a processing base 1, a fixed housing 2 and a motor 3. The top of the processing base 1 is provided with a fixed housing 2, and a motor 3 is arranged inside the fixed housing 2. The output end of a cylinder 7 is installed at the top of the processing base 1, and a fixed block 8 is installed at the output end of the cylinder 7. Fixed shafts 4 are arranged at the output ends of the fixed block 8 and the motor 3 through bearings. A tapered positioning block 5 is arranged on the outer wall of the fixed shaft 4. A rubber block 10 is arranged on the outer wall of the tapered positioning block 5, and a copper alloy bearing workpiece 6 is arranged between the outer walls of the rubber blocks 10. The output end of the motor 3 is connected to one side of the fixed shaft 4 through a coupling. By inserting the copper alloy bearing workpiece 6 into the position on the outer wall of the tapered positioning block 5, the tapered positioning block 5 is attached to the copper alloy bearing workpiece 6 through the rubber block 10. Then, start the cylinder 7 to push the tapered positioning block 5 at the position of the fixed block 8 into the outer wall of the copper alloy bearing workpiece 6. Since the shapes of the two tapered positioning blocks 5 can fix copper alloy bearing workpieces 6 of different diameters, the clamping range is improved, and the operation is simple and convenient to use.

[0020] Embodiment 2, as Figure 1-4 shown, the present invention provides a technical solution: a clamping fixture for processing copper alloy bearings, including an installation mechanism installed on one side of the fixed shaft 4 for fixing the position of the tapered positioning block 5. The installation mechanism includes a cross-shaped positioning groove 9 and a cross-shaped positioning block 13. A cross-shaped positioning groove 9 is opened on the inner wall of the tapered positioning block 5. A cross-shaped positioning block 13 is installed on one side of the fixed shaft 4, and the outer wall of the cross-shaped positioning block 13 is in contact with the inner wall of the cross-shaped positioning groove 9. Threaded grooves 11 penetrating the cross-shaped positioning groove 9 are opened at both ends of the tapered positioning block 5, and a positioning screw 12 is arranged inside the threaded groove 11. The outer wall of the positioning screw 12 is meshed with the inner wall of the threaded groove 11. The outer wall of the positioning screw 12 is provided with anti-slip lines. By driving the cross-shaped positioning block 13 by the fixed shaft 4 to insert into the inner wall of the cross-shaped positioning groove 9, and then rotating the positioning screw 12 to be meshed with the inner wall of the threaded groove 11, the positioning screw 12 is fixed in the tapered positioning block 5. This structure is convenient for installing between the tapered positioning block 5 and the fixed shaft 4, and is convenient for removal, so as to clamp copper alloy bearing workpieces 6 of different shapes.

[0021] Working principle: First, connect the external power supply. The operator can drive the cross-shaped positioning block 13 to insert into the inner wall of the cross-shaped positioning groove 9 through the fixed shaft 4. Then, rotate the positioning screw 12 to engage with the inner wall of the thread groove 11, so that the positioning screw 12 is fixed in the position of the conical positioning block 5. Then, the operator inserts the copper alloy bearing workpiece 6 into the position on the outer wall of the conical positioning block 5, so that the conical positioning block 5 is attached to the copper alloy bearing workpiece 6 through the rubber block 10. Next, start the cylinder 7 to push the conical positioning block 5 at the position of the fixed block 8 to insert into the outer wall of the copper alloy bearing workpiece 6. Since the shapes of the two groups of conical positioning blocks 5 can fix copper alloy bearing workpieces 6 with different diameters, at this time, start the motor 3 to drive the fixed shaft 4 to rotate, and then the conical positioning block 5 at the fixed shaft 4 drives the copper alloy bearing workpiece 6 to rotate, which is convenient for 360-degree rotary processing.
