[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-6 A positioning fixture for bearing processing includes a base 1 and two clamping and positioning components 4. A support column 2 is installed on the top of one end of the base 1, and the clamping and positioning components 4 are installed on the top of the support column 2. A cylinder 3 is installed on one end of the base 1, and the cylinder 3 drives the clamping and positioning components 4 to be installed.
[0025] The clamping and positioning assembly 4 includes a concave mounting block 41, a first clamping plate 42, a second clamping plate 43, a connecting rod 44, and an adjusting plate 45. One end of the concave mounting block 41 is provided with a first connecting post 411, and one end of the first clamping plate 42 is provided with a first rotating sleeve 421, which is rotatably fitted onto the first connecting post 411. One end of the second clamping plate 43 is provided with two second rotating sleeves 431, which are rotatably fitted onto the first connecting post 411. A support plate 8 is installed on the inner bottom of the first clamping plate 42 and the second clamping plate 43.
[0026] Meanwhile, two mounting blocks 6 are installed on the outer sides of clamping plate 1 42 and clamping plate 2 43, and a connecting post 3 7 is set between the two mounting blocks 6. Connecting post 2 441 and connecting sleeve 1 442 are respectively set at both ends of connecting rod 44. Connecting sleeve 1 442 is rotatably sleeved on connecting post 3 7. When connecting rod 44 is pulled, the angle between clamping plate 1 42 and clamping plate 2 43 can be adjusted because connecting sleeve 1 442 and connecting post 3 7 are rotatably connected.
[0027] Meanwhile, one end of the adjusting plate 45 is provided with two connecting sleeves 452. The two connecting sleeves 452 are respectively rotatably sleeved on both ends of the connecting post 441. When the adjusting plate 45 is pulled, the clamping plate 42 or the clamping plate 43 can be driven to rotate around the connecting post 411 as the axis, thereby realizing the adjustment of the angle between the clamping plate 42 and the clamping plate 43.
[0028] Furthermore, the adjusting plate 45 is provided with several limiting holes 451, and the concave mounting block 41 has two threaded holes 412 on both sides. A bolt 5 is inserted into the threaded hole 412 after passing through the limiting hole 451, thereby limiting the position of the adjusting plate 45 so that the included angle between the clamping plate 42 and the clamping plate 43 will not change.
[0029] Furthermore, two through slots 11 are provided at one end of the base 1. When the adjusting cylinder 3 drives the clamping and positioning assembly 4 to drive the clamping plate 42 and the clamping plate 43, the adjusting plate 45 can pass through the through slots 11 without interference, which facilitates adjustment.
[0030] In this embodiment, the bearing to be processed is first placed on the clamping and positioning assembly 4 on the support column 2, and the bottom of the bearing contacts the two support plates 8. Then, the cylinder 3 is started, and the cylinder 3 drives another clamping and positioning assembly 4 to move, thereby positioning and clamping the bearing between the two clamping and positioning assemblies 4.
[0031] When it is necessary to position and clamp a bearing of a different size, adjust the included angle between the two clamping and positioning components 4, clamp plate 1 42 and clamp plate 2 43. First, loosen bolt 5 and remove it from the threaded hole 412 and the limiting hole 451. Then, pull the adjusting plate 45. Under the connection of the connecting rod 44, clamp plate 1 42 will rotate around the connecting column 1 411 as the axis. Since the adjusting plate 45 and the connecting rod 44 are rotatably connected, they will not interfere with each other. When clamp plate 1 42 rotates to the appropriate angle, the limiting hole 451 is aligned with the threaded hole 412. After passing bolt 5 through the limiting hole 451, it is threaded into the threaded hole 412, thus completing the adjustment of the angle of clamp plate 1 42. Similarly, the angle adjustment method of clamp plate 2 43 is the same as that of clamp plate 1 42, and the degree of rotation of clamp plate 1 42 and clamp plate 2 43 must be the same. After completing the adjustment of the included angle between the two clamping and positioning components 4, clamp plate 1 42 and clamp plate 2 43, bearings of different sizes can be clamped and positioned.
[0032] In this invention, by changing the included angle between clamping plate 42 and clamping plate 43, bearings of different sizes can be adapted, and bearings of different sizes can be positioned and clamped without changing the positioning and clamping mold, which is extremely convenient.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
