Description

Technical Field

[0001] This application relates to the field of dual-purpose fixture technology, and in particular to double-sided dual-purpose clamping fixtures. Background Technology

[0002] In the gear forming process, the inner hole of the gear needs to be ground. Grinding optimizes the inner hole to improve the gear's operating efficiency and performance. The principle behind this is to use a grinding rod to process the inner hole, increasing its precision and smoothness, thus avoiding problems such as poor gear matching and noise during operation caused by low inner hole precision.

[0003] In existing technologies, gear-specific fixtures can only clamp one gear at a time, which affects the efficiency of grinding the inner hole of the gear.

[0004] Therefore, it is necessary to propose a double-sided, dual-purpose clamping fixture to improve the efficiency of gear inner hole grinding, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a double-sided, dual-purpose clamping fixture, which aims to solve the problem that in the prior art, gear-specific clamps can only clamp one gear at a time, affecting the efficiency of grinding the inner hole of the gear.

[0006] To achieve the above objectives, this application proposes a double-sided dual-purpose clamping fixture, comprising: a mounting base; an annular seat disposed on the mounting base; a first fixed clamping plate disposed on one side of the annular seat; a second fixed clamping plate disposed on the other side of the annular seat; a second movable plate disposed on the second fixed clamping plate, forming a clamping space between the second fixed clamping plate; and round holes, wherein the annular seat, the first fixed clamping plate, the second fixed clamping plate, and the second movable plate are all provided with round holes.

[0007] In some embodiments, the device further includes: a first countersunk hole, wherein the first countersunk hole is provided on the first fixing plate; and a second countersunk hole, wherein the second countersunk hole is provided on the second fixing plate, and the annular seat is provided with a through hole adapted to the first countersunk hole and the second countersunk hole.

[0008] In some embodiments, the device further includes threaded holes, with both the second fixed clamping plate and the second movable plate having threaded holes.

[0009] In some embodiments, it further includes a ring edge disposed on the first fixing plate.

[0010] In some embodiments, it further includes: a connecting portion, one end of which is connected to an annular seat, and the other end of which is connected to a mounting base.

[0011] In some embodiments, the mounting base is further provided with mounting holes.

[0012] This application proposes a double-sided, dual-purpose clamping fixture, comprising: a mounting base; an annular seat disposed on the mounting base; a first fixed clamping plate disposed on one side of the annular seat; a second fixed clamping plate disposed on the other side of the annular seat; a second movable plate disposed on the second fixed clamping plate, forming a clamping space between the two fixed clamping plates; and circular holes provided in the annular seat, the first fixed clamping plate, the second fixed clamping plate, and the second movable plate. Two different gear inner hole grinding fixtures are located on either side of the annular seat. The first fixed clamping plate and the first movable plate cooperate to clamp one gear, while the second fixed clamping plate and the second movable plate cooperate to clamp the other gear, allowing simultaneous clamping of two gears and grinding of their inner holes. This improves the grinding efficiency of gear inner holes, and the fact that the two gear inner hole grinding fixtures share a single mounting base and annular seat helps reduce the manufacturing cost of the fixture.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application proposes a double-sided dual-purpose clamping fixture, including: a mounting base 1; an annular seat 3, the annular seat 3 being disposed on the mounting base 1; a first fixing clamp 4, the first fixing clamp 4 being disposed on one side of the annular seat 3; a second fixing clamp 2, the second fixing clamp 2 being disposed on the other side of the annular seat 3; a second movable plate 8, the second movable plate 8 being disposed on the second fixing clamp 2, and a clamping space being formed between the second fixing clamp 2 and the second fixing clamp 2; and round holes, the annular seat 3, the first fixing clamp 4, the second fixing clamp 2 and the second movable plate 8 are all provided with round holes.

[0024] The mounting base 1 is the structural foundation of the double-sided dual-purpose clamping fixture, and all other structures on the double-sided dual-purpose clamping fixture are directly or indirectly connected to the mounting base 1. The two sides of the annular seat 3 are two different gear inner hole grinding jigs, which can clamp two gears at the same time and grind the gear inner holes.

[0025] The gear inner hole grinding and clamping fixture on one side includes a first fixed clamping plate 4 and a first movable plate 10. The first fixed clamping plate 4 is fixed on the annular seat 3. The grinding rod 9 for grinding the gear inner hole is inserted into the round hole of the first fixed clamping plate 4. At this time, the first gear 11 is placed on the first fixed clamping plate 4 and the grinding rod 9 passes through the inner hole of the first gear 11. The first movable plate 10 moves toward the first fixed clamping plate 4. The first movable plate 10 is provided with a clearance hole to avoid the grinding rod 9. The first gear 11 is fixed between the first movable plate 10 and the first fixed clamping plate 4, thus completing the clamping of the first gear 11.

[0026] In this embodiment, the inner diameter of the circular hole is slightly larger than the outer diameter of the grinding rod 9. The first moving plate 10 moves under the drive of a linear power source such as a cylinder.

[0027] The gear inner hole grinding and clamping fixture on the other side includes a second fixed clamping plate 2 and a second movable plate 8. During the gear clamping process, the second gear 7 is placed on the second fixed clamping plate 2, and the positioning rod 13 is passed through the round hole of the second fixed clamping plate 2 and the inner hole of the second gear 7 to ensure that the second gear 7 and the round hole are coaxial. Then, the second movable plate 8 is installed on the second fixed clamping plate 2 to fix the second gear 7 in the clamping space. Then, the grinding rod 9 is brought into contact with the inner holes of the first gear 11 and the second gear 7. The grinding rod 9 is rotated under the drive of the machine tool, so that the grinding of the inner holes of the two gears can be completed at the same time.

[0028] In this embodiment, the mounting base 1 can move circumferentially along the annular seat 3 under the action of an external drive to improve the polishing effect.

[0029] Specifically, the two sides of the annular seat 3 are two different gear inner hole grinding fixtures. The first fixed clamping plate 4 cooperates with the first moving plate 10 to clamp the first gear 11, and the second fixed clamping plate 2 and the second moving plate 8 cooperate to clamp the second gear 7. Both gears can be clamped simultaneously for grinding their inner holes. This improves the grinding efficiency of the gear inner holes, and the fact that the two gear inner hole grinding fixtures share a single mounting base 1 and annular seat 3 helps reduce the manufacturing cost of the fixtures.

[0030] See Figure 3 and Figure 4As shown, in some embodiments, it further includes: a first countersunk hole 15, which is provided on the first fixing plate 4; a second countersunk hole 14, which is provided on the second fixing plate 2; and an annular seat 3, which is provided with a through hole adapted to the first countersunk hole 15 and the second countersunk hole 14. The screw is partially located in the first countersunk hole 15 and partially located in the second countersunk hole 14. The diameter of the through hole on the annular seat 3 is larger than the outer diameter of the screw. A locking nut is screwed to each end of the screw. One locking nut abuts against the first fixing plate 4, and the other locking nut abuts against the second fixing plate 2, thereby realizing the connection between the first fixing plate 4 and the second fixing plate 2 and the annular seat 3.

[0031] In this embodiment, the inner diameter of the large hole of the second countersunk hole 14 is larger than the outer diameter of the locking nut, and the depth of the large hole of the second countersunk hole 14 is greater than the thickness of the locking nut. The first countersunk hole 15, the second countersunk hole 14, and the through hole are all arranged at intervals along the circumference.

[0032] See Figure 1 and Figure 2 As shown, in some embodiments, it further includes: threaded holes 16, both the second fixed clamping plate 2 and the second movable plate 8 are provided with threaded holes 16. The second gear 7 is provided with matching mounting holes, and screws are provided on the second fixed clamping plate 2 and the second movable plate 8. By rotating the screws, the second movable plate 8 can be moved towards the second fixed clamping plate 2 to complete the fixation of the second gear 7.

[0033] In this embodiment, since the grinding rod 9 and the driving mechanism of the grinding rod 9 are located on the other side of the annular seat 3, it is difficult to deploy the driving structure on the second moving plate 8 due to space constraints. The structural design of the threaded hole 16 and the screw can effectively fix the second gear 7.

[0034] The first fixed clamping plate 4, the second fixed clamping plate 2, and the second movable plate 8 are all detachably connected to the ring seat 3. In actual use, the first fixed clamping plate 4, the second fixed clamping plate 2, and the second movable plate 8 of different specifications can be replaced according to the specifications of the gear to enhance the practicality of the double-sided dual-purpose clamping fixture.

[0035] The diameter of the circular hole on the annular seat 3 can be larger than the diameter of the circular holes on the first fixed clamping plate 4, the second fixed clamping plate 2, and the second movable plate 8, so that the annular seat 3 can accommodate more specifications of the first fixed clamping plate 4, the second fixed clamping plate 2, and the second movable plate 8.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, it further includes a ring edge 12, which is disposed on the first fixed clamping plate 4. The ring edge 12 is convenient for temporarily supporting the first gear 11, facilitating the clamping of the first gear 11, and also helps to maintain the coaxiality of the first gear 11 and the circular hole of the first fixed clamping plate 4. The thickness of the ring edge 12 is less than the thickness of the first gear 11, so as to avoid interference between the ring edge 12 and the first moving plate 10.

[0037] See Figure 1 and Figure 2 As shown, in some embodiments, it further includes a connecting portion 5, one end of which is connected to the annular seat 3, and the other end of which is connected to the mounting base 1. The connecting portion 5 is integrally formed with the annular seat 3, and the connecting portion 5 is welded to the mounting base 1. Along the direction away from the annular seat 3, the cross-sectional area of ​​the connecting portion 5 gradually increases.

[0038] See Figure 1 and Figure 2 As shown, in some embodiments, it further includes: a mounting hole 6, which is provided on the mounting base 1. The mounting hole 6 is used to mount the mounting base 1 onto the machine tool.

All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
