Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for machining spherical metal parts. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for processing or inspection. Also known as a clamp, broadly speaking, any device used to quickly, conveniently, and safely install a workpiece in any step of the manufacturing process can be called a fixture. When processing and inspecting spherical metal parts, a spherical metal part fixture is needed to achieve the desired fixation. However, existing spherical metal part fixtures have limitations in practical use. Because the surface of the spherical metal part is curved, and the traditional fixture holds it on a flat surface, the contact area is small. Furthermore, the very smooth surface of the fixture results in low friction between the fixture and the spherical metal part, potentially causing it to fall during clamping. This leads to poor stability during use. Therefore, we propose a fixture for processing spherical metal parts. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a fixture for machining spherical metal parts. This utility model solves the problem that existing fixtures for spherical metal parts suffer from drawbacks in practical use. Because the surface of the spherical metal part is arc-shaped, and the traditional fixture holds it on a flat surface, the contact area of ​​the fixture is small during machining. Furthermore, due to the very smooth surface of the fixture, the friction between the fixture and the spherical metal part is low, which may cause it to fall during clamping, resulting in poor stability during use.

[0004] This utility model discloses a jig for processing spherical metal parts, including a base plate. Fixed plates are provided on both sides of the base plate, and a threaded rod is provided between the two fixed plates. A housing is provided on the side of one fixed plate away from the base plate. A shaft is inserted into the middle of the upper end of the housing. A first bevel gear is provided at one end of the shaft inside the housing. A second bevel gear meshing with the first bevel gear is provided on the threaded rod. A movable block is provided on the threaded rod, and a movable plate is fixedly connected above the movable block. Two symmetrical first support plates are provided above the movable plate, and a movable annular clamping plate is fixedly connected above the two first support plates. An mounting plate is provided above the fixed plate on the side away from the housing, and two second support plates are provided on the mounting plate. A fixed annular clamping plate is fixedly connected above the two second support plates.

[0005] In the above scheme, the movable plate is fixedly connected to the support base above the first support plate, and an avoidance groove is provided in the middle of the upper part of the support base.

[0006] In the above scheme, the first support plate and the movable plate, as well as the second support plate and the mounting plate, are fixedly connected by reinforcing plates.

[0007] In the above scheme, rubber gaskets are provided on the side of the moving annular clamping plate and the fixed annular clamping plate that are close to each other.

[0008] In the above scheme, the base plate is located between the two fixed plates and is provided with guide rails, and the movable plate is provided with a slider that matches the guide rails.

[0009] In the above scheme, mounting holes are provided at all four corners of the base plate.

[0010] In the above scheme, the shaft is fixedly connected to the rotating disk, and a rotating handle is provided on the top of the rotating disk.

[0011] The advantages and beneficial effects of this utility model are as follows: This utility model provides a fixture for processing spherical metal parts, which is equipped with a threaded rod, a bevel gear transmission mechanism, a movable block, and a movable plate. The operator only needs to turn the handle to drive the first bevel gear to rotate through the shaft. The first bevel gear drives the second bevel gear meshing with it to rotate, thereby causing the threaded rod to rotate. The movable block moves on the threaded rod and drives the movable plate and the moving annular clamping plate to move closer to or away from the fixed annular clamping plate, realizing the clamping and loosening of the spherical metal parts. The adjustment is convenient and quick, and the adaptability is strong. Rubber gaskets are set on the inner side of the moving annular clamping plate and the fixed annular clamping plate, which can play a buffering and protective role on the surface of the spherical metal parts during the clamping process, avoiding scratches or extrusion deformation of the workpiece surface, and effectively ensuring the processing quality of the spherical metal parts. This fixture has a simple structure, is easy to operate, has good clamping stability, avoids the phenomenon of spherical metal falling off, and ensures the processing quality of spherical metal parts.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figure 1-2 As shown, this utility model is a jig for processing spherical metal parts, including a base plate 1. Fixed plates 2 are provided on both sides of the base plate 1. A threaded rod 3 is provided between the two fixed plates 2, with both ends of the threaded rod 3 movably connected to the fixed plates 2. A housing 4 is provided on the side of one of the fixed plates 2 away from the base plate 1. A shaft 5 is inserted into the middle of the upper end of the housing 4, and the shaft 5 is movably connected to the housing 4. A first bevel gear 6 is provided at one end of the shaft 5 inside the housing 4. A second bevel gear 7 meshing with the first bevel gear 6 is provided on the threaded rod 3. A movable block 8 is provided on the threaded rod 3, and the upper part of the movable block 8 is fixedly connected to a movable plate 9. When the shaft 5 is rotated, the shaft 5 drives the first bevel gear 6 to rotate. The second bevel gear 7, meshing with the first bevel gear 6, begins to rotate under the drive of the first bevel gear 6. Through the transmission of the second bevel gear 7, the... The threaded rod 3 also rotates. When the threaded rod 3 rotates, the movable block 8 can reciprocate horizontally on the movable plate 9. The movable plate 9 moves accordingly through the transmission of the movable block 8. Two symmetrical first support plates 10 are provided above the movable plate 9. The two first support plates 10 are fixedly connected to the movable annular clamping plate 11. A mounting plate 12 is provided above the fixed plate 2 on the side away from the box body 4. Two second support plates 13 are provided on the mounting plate 12. The two second support plates 13 are fixedly connected to the fixed annular clamping plate 14. When the movable plate 9 moves, the movable annular clamping plate 11 moves accordingly through the transmission of the first support plates 10. When the movable annular clamping plate 11 and the fixed annular clamping plate 14 approach each other, the spherical metal parts can be clamped through the mutual cooperation between the movable annular clamping plate 11 and the fixed annular clamping plate 14.

[0017] The movable plate 9 is fixedly connected to the support base 15 above the first support plate 10. The support base 15 has an avoidance groove 16 in the middle of its upper part. The avoidance groove 16 can avoid the bottom or part of the protruding structure of the spherical metal part, so as to avoid interference between the support base 15 and the processing tool or the processing part of the spherical metal part during the processing. At the same time, it can also provide more stable support for the spherical metal part.

[0018] The first support plate 10 and the movable plate 9, as well as the second support plate 13 and the mounting plate 12, are fixedly connected by a reinforcing plate 17. The reinforcing plate 17 effectively enhances the connection strength between the first support plate 10 and the movable plate 9, and between the second support plate 13 and the mounting plate 12, preventing the support plate from bending or breaking during clamping and processing, and improving the overall structural stability and service life of the fixture.

[0019] Both the moving annular clamping plate 11 and the fixed annular clamping plate 14 are provided with rubber washers 18 on their adjacent sides. The rubber washers 18 have good elasticity and wear resistance. On the one hand, they can increase the friction between the annular clamping plate and the surface of the spherical metal part, prevent the spherical metal part from sliding during processing, and ensure the stability of clamping. On the other hand, during clamping, the rubber washers 18 can play a buffering role, avoiding direct rigid contact between the annular clamping plate and the surface of the spherical metal part, thereby effectively preventing the surface of the spherical metal part from being scratched or deformed by squeezing, and protecting the processing quality of the workpiece.

[0020] The base plate 1 is provided with guide rails 20 between the two fixed plates 2. The movable plate 9 is provided with a slider 21 that matches the guide rails 20. The slider 21 is slidably connected to the guide rails 20. The cooperation between the guide rails 20 and the slider 21 can provide guidance for the movement of the movable plate 9, ensuring that the movable plate 9 moves smoothly along a straight line under the drive of the threaded rod 3, and preventing the movable plate 9 from deviating.

[0021] The base plate 1 has mounting holes 19 at each of its four corners. The entire fixture can be fixedly installed on the machine tool using bolts or other fasteners through the mounting holes 19, preventing the fixture from moving as a whole during the processing and ensuring the stability and safety of the processing.

[0022] The shaft 5 is fixedly connected to the rotating disk 22. The rotating disk 22 is provided with a rotating handle 23. The rotating handle 23 makes it convenient for the operator to rotate the shaft 5. By rotating the handle 23, the rotating disk 22 and the shaft 5 are driven to rotate, thereby driving the first bevel gear 6 and the second bevel gear 7 to transmit power.

[0023] Specifically, in this utility model, when the rotating handle 23 is rotated, the rotating handle 23 drives the rotating disk 22 and the shaft 5 to rotate. The shaft 5 drives the first bevel gear 6 to rotate. The second bevel gear 7, which meshes with the first bevel gear 6, begins to rotate under the drive of the first bevel gear 6. Through the transmission of the second bevel gear 7, the threaded rod 3 also rotates. When the threaded rod 3 rotates, the movable block 8 can reciprocate horizontally on the movable plate 9. Through the transmission of the movable block 8, the movable plate 9 also moves. When the movable plate 9 moves, through the transmission of the first support plate 10, the moving annular clamping plate 11 also moves. When the moving annular clamping plate 11 and the fixed annular clamping plate 14 approach each other, through the mutual interaction between the moving annular clamping plate 11 and the fixed annular clamping plate 14... The combination allows for clamping of spherical metal parts. The clearance groove 16 can avoid the bottom or some protruding structures of the spherical metal parts, preventing interference between the support seat 15 and the processing tool or the processing part of the spherical metal parts during processing. At the same time, it can also provide more stable support for the spherical metal parts. The rubber gasket 18 has good elasticity and wear resistance. On the one hand, it can increase the friction between the annular clamping plate and the surface of the spherical metal parts, preventing the spherical metal parts from sliding during processing and ensuring the stability of clamping. On the other hand, during the clamping process, the rubber gasket 18 can play a buffering role, avoiding direct rigid contact between the annular clamping plate and the surface of the spherical metal parts, thereby effectively preventing the surface of the spherical metal parts from being scratched or deformed by squeezing, and protecting the processing quality of the workpiece.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
