Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a precision machining fixture supported by multiple bearings. Background Technology

[0002] Tooling, also known as processing equipment, is a general term for the devices used in the processing of equipment components. When bearings are used, they need to be assembled and fixed by a support seat. Depending on the diameter of the bearing, different specifications of bearing support seats are often required. In order to reduce the replacement and use costs of bearing seats, existing technologies will set a detachable assembly ring at the bearing mounting position of the bearing seat. When bearings of different diameters need to be used, only the appropriate assembly ring needs to be selected to complete the use of multiple specifications of bearing seats, which has a wide range of applications.

[0003] Because bearings need to maintain relatively precise axial rotation during use, bearing support seats often require precision machining of themselves and the inner ring of the assembly ring during processing. During the processing, operators often need to stand by and wait. After one bearing support seat is processed, another bearing support seat to be processed is clamped and fixed, and the alignment is maintained. The operation is cumbersome, inconvenient, and affects the processing efficiency. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1-10 This application provides the following three preferred embodiments.

[0034] Example 1

[0035] A precision machining fixture supported by bearings has two symmetrically arranged feeding racks 2 on both sides of the upper end of the machining base 1. A material feeding area is provided between the two feeding racks 2. A narrow conveyor belt 5 is horizontally arranged on one side of the feeding rack 2 within the material feeding area. A bearing support seat 6 is horizontally placed on the upper end of the two narrow conveyor belts 5. A lifting control cavity 7 is vertically opened at the lower end of the side of the machining base 1 located in the material feeding area. The lifting control component is horizontally arranged in the lifting control cavity 7 and includes a lifting seat plate 9. A positioning component is located on the upper end of the lifting seat plate 9 and includes four arc-shaped positioning plates 14. A fixing component is vertically and movably inserted into the side of the feeding rack 2 near the lifting control cavity 7 and includes a fixing pull plate 21. Water is installed inside the lifting control cavity 7. The system is equipped with a traction assembly, which includes a traction plate 16. Two traction arms 20 are horizontally symmetrically arranged on both sides of the traction plate 16. One side of each of the four traction arms 20 passes through both sides of the processing base 1 and is movably inserted into one side of each of the two fixed traction plates 21. Lifting control cavity 7 has vertically symmetrically arranged lifting guide grooves on both sides. Lifting screws 8 are vertically arranged in each lifting guide groove. Lifting seat plate 9 is horizontally inserted into two lifting guide grooves on both sides and movably sleeved with two lifting screws 8. The cross-section of the lifting seat plate 9 is smaller than the cross-section of the lifting control cavity 7. A collection groove 32 is arranged around the upper end of the lifting seat plate 9 to control the up and down movement of the lifting seat plate 9. The driving power can be a servo motor commonly used in the prior art.

[0036] The upper end of the lifting seat plate 9 is provided with four pin seats 13 arranged in a circular array. The lower ends of four arc-shaped positioning plates 14 are movably sleeved with the four pin seats 13 respectively. Each side of the arc-shaped positioning plate 14 sleeved with the pin seats 13 is provided with a torsion spring 15. The four arc-shaped positioning plates 14 are combined to form a conical structure. An auxiliary through rod 10 is vertically and movably inserted into the center of the lifting seat plate 9. A sealing seat 11 is horizontally provided at the lower end of the auxiliary through rod 10. A tension spring 12 is sleeved between the sealing seat 11 and the lifting seat plate 9 on the auxiliary through rod 10. The upper end of the auxiliary through rod 10 is... In its natural state, the bearing support seat 6 is inserted into the conical structure composed of four arc-shaped positioning plates 14. When the bearing support seat 6 is transported to the top of the lifting control cavity 7 by two narrow conveyor belts 5, it is identified by the positioning sensor. At this time, the lifting screw 8 is driven to rotate by the motor, and the lifting seat plate 9 rises horizontally under the control of the lifting screw 8. During the rise, the conical structure composed of arc-shaped positioning plates 14 is driven to insert into the inner ring of the bearing support seat 6. Then, under the action of the characteristics of the conical structure, the bearing support seat 6 is aligned and positioned.

[0037] Both feeding racks 2 have vertical slots extending through their sides near the lifting control cavity 7. Two fixed pull plates 21 are vertically and movably inserted into the two slots. A pressure plate is horizontally positioned at the upper end of each fixed pull plate 21, extending through the feeding rack 2. When the fixed pull plate 21 descends to its maximum extent, the pressure plate presses against the upper end of the bearing support seat 6. Several reset guide rods 17 are vertically and symmetrically positioned at the lower end of the lifting control cavity 7. A traction plate 16 is horizontally positioned within the lifting control cavity 7 and movably sleeved with several reset guide rods 17. Each reset guide rod 17 is sleeved with a first spring 18 at the lower end of the traction plate 16. Two first strip slots 19 are symmetrically extended through both sides of the lifting control cavity 7. Four traction arms 20 are horizontally and movably positioned through the four first strip slots 19. The fixed pull plates 21 have... Two second strip-shaped grooves 22 are symmetrically provided. Each second strip-shaped groove 22 is vertically provided with a spring rod 23. Four pulling arms 20 pass through one side of the first strip-shaped groove 19 and are respectively inserted into the four second strip-shaped grooves 22 and movably sleeved with the spring rods 23. The spring rods 23 are all sleeved with second springs 24 at the lower end of the pulling arms 20. The length of the first strip-shaped groove 19 is greater than the length of the second strip-shaped groove 22. The lifting seat plate 9 is controlled to descend. When the lower end of the lifting seat plate 9 contacts the upper end of the pulling plate 16, the arc-shaped positioning plate 14 has completely disengaged from the bearing support seat 6. The lifting seat plate 9 continues to descend. The pulling plate 16 pulls the fixed pull plate 21 downward along the first strip-shaped groove 19 through the four pulling arms 20, so that the pressure plate of the fixed pull plate 21 presses and fixes the upper side of the bearing support seat 6.

[0038] The lifting seat plate 9 is provided with corresponding holes directly above the reset guide rod 17. When the lifting seat plate 9 descends, the reset guide rod 17 passes through the corresponding holes and does not affect the normal descent of the lifting seat plate 9.

[0039] Neither the pressure plate of the fixed pull plate 21 nor the narrow conveyor belt 5 obstructs the inner ring of the bearing support seat 6 to be precision machined. A precision machining equipment is set directly above the arc-shaped positioning plate 14. At this time, the machining equipment is vertically lowered, and the inner ring of the bearing support seat 6 can be precision machined (including turning, grinding and polishing).

[0040] The precision machining fixture with multi-purpose bearing support disclosed in Embodiment 2 of this invention has a structure that is basically the same as that in Embodiment 1, except that: a clearance hole is provided through the center of the pull plate 16; a top seat is provided at the center of the lower end of the lifting control cavity 7; a release rod 25 is vertically provided at the upper end of the top seat; a piston groove is provided at the center of the sealing seat 11; a docking hole 30 is provided at the center of the lower end of the piston groove; the docking hole 30 is correspondingly provided with the release rod 25; and an alignment groove 26 is provided through the center of the upper end of the auxiliary rod 10, which is connected to the piston groove. A connecting groove 28 is provided. A sealing piston 27 is horizontally provided at the lower end of the piston groove. A piston spring 29 is provided at the upper end of the sealing piston 27. When the sealing seat 11 is lowered to the maximum extent, the release rod 25 passes through the docking hole 30 and pushes the lower end of the sealing piston 27. An auxiliary pipe joint 31 is provided on one side of the piston groove, passing through the sealing seat 11. In the natural state, the sealing piston 27 blocks the connecting groove 28 and the auxiliary pipe joint 31. When the upper end of the release rod 25 is fully inserted into the piston groove, the sealing piston 27 moves away from the connecting groove 28 and the auxiliary pipe joint 31.

[0041] When the lifting seat plate 9 drives the pulling plate 16 and the fixed pulling plate 21 to descend until the pressure plate of the fixed pulling plate 21 contacts the upper end of the bearing support seat 6, the lifting seat plate 9 continues to move downward horizontally. The upper end of the release rod 25 is inserted into the piston groove of the sealing seat 11, and the auxiliary pipe joint 31 is connected to the connecting groove 28 and the alignment groove 26. The lifting seat plate 9 continues to descend further, and the lifting seat plate 9 compresses the tension spring 12. The upper end of the auxiliary through rod 10 rises relative to the lifting seat plate 9, pushing the four arc-shaped positioning plates 14 to open to the four sides. At this time, when the auxiliary pipe joint 31 is connected to the coolant, cooling gas or negative pressure dust suction system, multi-functional auxiliary processing for precision machining can be realized.

[0042] The precision machining fixture for multi-purpose bearing support disclosed in Embodiment 3 of this invention has a structure that is basically the same as that in Embodiment 2. The difference is that: both sides of the upper end of the machining base 1 are provided with rail grooves 4, and the lower ends of the two feeding racks 2 near the rail grooves 4 are provided with counters 3. The counters 3 are horizontally inserted into the rail grooves 4. The machining base 1 is horizontally provided with an adjustment control box between the two counters 3. A servo control motor can be installed in the adjustment control box. A double-ended lead screw is horizontally inserted into one side of the adjustment control box. The two sides of the double-ended lead screw pass through the counters 3 of the two feeding racks 2 through lead screw sleeves. When the bearing support seat 6 to be processed has different sizes, the width of the material feeding area can be adjusted by adjusting the position of the feeding rack 2 to keep the narrow conveyor belt 5 in contact with the lower end of the bearing support seat 6 without affecting the precision machining of the inner ring. It has a wide range of applications, is simple and convenient to operate, and is worry-free to operate.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
