Description

Technical Field

[0001] The invention relates to a numerical control machining auxiliary fixing device, in particular to a bearing upper support fixing device. Background Art

[0002] The bearing support is an important component of agricultural machinery vehicles, used in steering mechanisms or load mechanisms to fix and support shaft workpieces, such as Figure 1 The figure shows a schematic diagram of the structure of the support on the bearing, which includes a workpiece body 10-1 and a workpiece double-ear seat 10-2, wherein the workpiece body 10-1 includes fixing parts at both ends and a recessed plane, and there are many processing surfaces. In the prior art, the processing of the support on the bearing requires multiple clamping processes, and each clamping means a decrease in efficiency.

[0003] In addition, although some existing technologies attempt to improve processing efficiency by reducing the clamping process, it is difficult to ensure the clamping effect due to the irregular shape of the main part of the support on the bearing, and any looseness will lead to a decrease in processing accuracy. Summary of the invention

[0004] The purpose of the present invention is to provide a bearing upper support fixing device, which positions the support bearing upper support by designing a front fork wedge and a reference frame, and is clamped in combination with a rotating pressure plate. Since the clamping and positioning are concentrated on the double-ear seats of the workpiece, most of the surface of the workpiece body is not blocked, so that more processing surfaces can be exposed, thereby achieving the effect of reducing the clamping process during the processing and ensuring the fixing effect.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A bearing upper support fixing device comprises a bottom plate and two connecting plates respectively arranged on both sides of the bottom plate, a front fork wedge, a reference square frame, a rotating pressure plate, a clamping pad, and a clamping bolt.

[0007] The front fork wedge block, the reference square frame and the clamping pad are all arranged on the bottom plate. The front fork wedge block is located near a connecting plate and is connected to the connecting plate by a stud screw. The reference square frame is arranged near another connecting plate and is used to support one side of the workpiece body of the upper support of the bearing. The front fork wedge block is provided with a wedge head on the side facing the reference square frame for inserting into the center of the workpiece double-ear seat supporting the upper support of the bearing. The width of the projection area of ​​the wedge head on the bottom plate gradually increases from one end near the reference square frame to the other end.

[0008] The rotating pressure plate includes a pressure plate root and a pressure plate body. The pressure plate root is rotatably connected to the clamping pad through a rotating shaft bolt. One end of the pressure plate body is fixed to the pressure plate root, and the other end is inserted into the workpiece double-ear seat and locked to the base plate by the clamping bolt.

[0009] The front fork wedge is symmetrical with respect to the mid-vertical plane of the bottom plate, wherein the mid-vertical plane of the bottom plate is a plane perpendicular to the bottom plate and passing through the axes of the two connecting plates.

[0010] The reference frame is symmetrical with respect to the vertical plane of the base plate.

[0011] A sliding groove for sliding the rotating shaft bolt is arranged on the root of the pressing plate. The rotating shaft bolt is arranged parallel to the bottom plate and passes through the sliding groove and moves along the sliding groove to approach or move away from the front fork wedge.

[0012] The movement direction of the rotating shaft bolt is parallel to the bottom plate.

[0013] The pressing plate body is provided with a sliding groove for sliding the clamping bolt, the sliding groove is parallel to the bottom plate and perpendicular to the connecting plate, and one end of the sliding groove extends to the edge of the pressing plate body.

[0014] The length of the slide groove is equal to the width of the slide groove along the length direction of the slide groove.

[0015] A hollow groove is arranged on the root of the pressing plate.

[0016] The threads at both ends of the stud screw are arranged in opposite directions.

[0017] The device also includes a sliding gasket. A sliding block is provided at the bottom of the front fork wedge. A sliding rail for the sliding block is provided on the bottom plate. The bottom surface of the sliding block passes through the sliding rail to the other side of the bottom plate and is connected to the sliding gasket through connecting bolts. The sliding block is set tightly against the bottom plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The support on the support bearing is positioned by designing the front fork wedge and the reference square frame, and is clamped in combination with the rotating pressure plate. Since the clamping and positioning are concentrated on the double-ear seat of the workpiece, most of the surface of the workpiece body is not blocked, so that more processing surfaces can be exposed, thereby reducing the clamping process during the processing and ensuring the fixing effect.

[0020] 2. The front fork wedge is symmetrical with respect to the vertical plane of the bottom plate, which improves stability during rotation.

[0021] 3. The reference frame is symmetrical with respect to the vertical plane of the base plate, which improves stability during rotation.

[0022] 4. The setting of the sliding groove can realize the position adjustment of the rotating pressure plate, thereby improving the efficiency of taking and placing the support on the support bearing.

[0023] 5. The movement direction of the pivot bolt is parallel to the base plate, which can reduce space occupation while improving stability.

[0024] 6. The threads at both ends of the stud screw are set in reverse to reduce space occupation.

DETAILED DESCRIPTION

[0034] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0035] A bearing upper support fixing device, such as Figure 2 and Figure 3 As shown, it includes a base plate 1 and two connecting plates 5 respectively arranged on both sides of the base plate 1, and also includes a front fork wedge 6, a reference square frame 3, a rotating pressure plate 9, a clamping pad 4, and a clamping bolt 11.

[0036] The front fork wedge block 6, the reference frame 3 and the clamping pad 4 are all arranged on the bottom plate 1. The front fork wedge block 6 is located near a connecting plate 5 and is connected to the connecting plate by a stud screw 7. The reference frame 3 is arranged near another connecting plate 5 and is used to support one side of the workpiece body 10-1 of the bearing upper support 10. The front fork wedge block 6 is provided with a wedge head on the side facing the reference frame 3 for inserting into the center of the workpiece double-ear seat 10-2 supporting the bearing upper support 10. The width of the projection area of ​​the wedge head on the bottom plate 1 gradually increases from one end near the reference frame 3 to the other end.

[0037] like Figure 6 As shown, the rotating pressure plate 9 includes a pressure plate root 9-1 and a pressure plate body 9-2. The pressure plate root 9-1 is rotatably connected to the clamping pad 4 through the shaft bolt 8. One end of the pressure plate body 9-2 is fixed to the pressure plate root 9-1, and the other end is inserted into the workpiece double-ear seat 10-2 and then locked on the base plate 1 by the clamping bolt 11.

[0038] The support bearing upper support 10 is positioned by designing the front fork wedge 6 and the reference frame 3, and is clamped in combination with the rotating pressure plate 9. Since the clamping and positioning are concentrated on the workpiece double-ear seat 10-2, most of the surface of the workpiece body 10-1 is not blocked, so that more processing surfaces can be exposed, thereby achieving the effect of reducing the clamping process during the processing and ensuring the fixing effect.

[0039] In most embodiments, the front fork wedge 6 is symmetrical with respect to the vertical plane in the bottom plate 1, wherein the vertical plane in the bottom plate 1 is a plane perpendicular to the bottom plate 1 and passing through the axes of the two connecting plates 5, thereby improving stability during rotation.

[0040] Similarly, in most embodiments, the reference frame 3 is symmetrical with respect to the vertical plane of the base plate 1 to improve stability during the rotation process.

[0041] In most embodiments, a sliding groove 9-1-1 for sliding of the pivot bolt 8 is provided on the root 9-1 of the pressure plate. The pivot bolt 8 is arranged parallel to the base plate 1, passes through the sliding groove 9-1-1, and moves along the sliding groove 9-1-1 to approach or move away from the front fork wedge 6. The setting of the sliding groove 9-1-1 can realize the position adjustment of the rotating pressure plate 9, thereby improving the efficiency of taking and placing the support 10 on the support bearing.

[0042] In addition, in some embodiments, the movement direction of the rotating shaft bolt 8 is parallel to the base plate 1, which can reduce the space occupied and improve stability.

[0043] In some embodiments, a slide groove 9-2-1 for the clamping bolt 11 to slide is provided on the pressure plate body 9-2. The slide groove 9-2-1 is parallel to the bottom plate 1 and perpendicular to the connecting plate 5, and one end of the slide groove 9-2-1 extends to the edge of the pressure plate body 9-2. In this embodiment, the length of the slide groove 9-2-1 is equal to the width of the slide groove 9-1-1 along the length direction of the slide groove 9-2-1. In this way, the occupied space can be reduced. Of course, in other embodiments, other methods can also be used, such as the length of the slide groove 9-2-1 is slightly shorter. In this design, there is a step of sliding the clamping bolt 11 into the slide groove 9-2-1 during the clamping process.

[0044] In addition, in most embodiments, a hollow groove 9-1-2 is provided on the root 9-1 of the pressure plate, thereby reducing weight and saving energy.

[0045] In this embodiment, the threads at both ends of the stud screw 7 are arranged in opposite directions, which can reduce the space occupied. Of course, in some embodiments, other methods can also be used. For example, the threads at both ends of the stud screw 7 are in the same direction, but the threads in the front fork wedge 6 and the connecting plate 5 are in opposite directions, which can also achieve a similar effect.

[0046] In this embodiment, if Figure 4 As shown, the device also includes a sliding gasket 2, such as Figure 7 As shown, a slider 6-1 is provided at the bottom of the front fork wedge 6. Figure 5 As shown, a slide rail 1-1 for sliding a slider 6-1 is provided on the base plate 1. The bottom surface of the slider 6-1 passes through the slide rail 1-1 to the other side of the base plate 1 and is connected to the sliding gasket 2 through a connecting bolt 12. The slider 6-1 is arranged tightly on the base plate 1. By designing the sliding gasket 2 and the slider 6-1, the supporting force of the base plate 1 on the sliding gasket 2 can be used to offset the rotational torque generated by the pushing force of the stud screw 7 pushing the front fork wedge 6.

[0047] When the device of the present application is used, first, the front fork wedge 6 and the rotating pressure plate 9 are in a floating state, and the workpiece, that is, the support bearing upper support 10 is placed on the bottom plate 1, so that its side is flush with the reference frame 3, and the stud screw 7 is turned to move the front fork wedge 6 along the slide rail 1-1 of the bottom plate 1, and contact between the two ears of the workpiece double ear seat 10-2 to complete the centering positioning. Then the rotating pressure plate 9 is translated, rotated and pressed on the workpiece, and the rotating pressure plate 9 is moved forward to cooperate with the clamping bolt 11, and the clamping bolt 11 is locked. The workpiece is clamped by force, and the processing starts after the fixation is completed. The milling, drilling, boring and other processes are completed.
