Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing tools, in particular to a grinding fixture for indexable blades. Background Art

[0002] With the rapid development of advanced manufacturing technology, the performance and precision requirements of cutting tools, as one of the key factors in cutting processing technology, are constantly improving.

[0003] The existing side pressure fixtures are similar in design, showing certain similarities in terms of overall structure and basic functions, but they generally have a key defect: the blade can only be positioned by the side pressure head and the positioning piece, which directly limits the scope of application of the fixture and the ability of grinding processing. Specifically, these side pressure fixtures can only rely on the side pressure head and the V-shaped positioning piece on the positioning piece when positioning the blade. Although this positioning method can achieve the initial positioning of the blade to a certain extent, its limitations are also very obvious. Many types of blades cannot be ground out, especially blades with a back angle on the periphery. What is more serious is that the accuracy of the ground blades is often not high, or even unstable. For those blades that require high-precision grinding, the positioning accuracy of the side pressure head and the V-shaped positioning piece often cannot meet the requirements, which will cause positioning deviations during the grinding process, thereby affecting the grinding accuracy. Obviously, using these fixtures and grinding processes to process blades, the types and grinding accuracy of blades are limited. Blades with back angles on the peripheral surfaces cannot be ground out in large quantities, which cannot meet the needs of modern development that strives for excellence.

[0034] The present invention will be further illustrated and described below in conjunction with the accompanying drawings and embodiments.

[0035] Embodiment 1

[0036] like Figures 1 to 7 As shown, this embodiment provides an indexable insert grinding fixture, including a fixture body component 1, an automatic rotating shaft base 2, a jig-like part 3, a pressed product component 4, a blowing component 5 and a rear positioning component 6.

[0037] The clamp body component 1 includes an output cylinder 11, a floating joint 12, a wedge clamping block 13, a clamp body 14, a compression spring fixing part 15, a compression spring 16, a roller follower 17, a rotating shaft output rod 18, a rotating shaft 110 and a positioning plate adjustment part 19; the top of the clamp body component 1 is used to place, position and clamp the blade 8.

[0038] The clamp body 14 is the main part of the clamp body component 1. The output cylinder 11 and the wedge clamping block 13 are arranged opposite to each other and are installed inside the clamp body component 1. The output cylinder 11 can provide a clamping power source. The wedge clamping block 13 is connected to the output shaft of the output cylinder 11 through the floating joint 12; the output rod 18 is arranged on the clamp body 14 through the horizontal rotating shaft 110, the lower end of the compression spring 16 is abutted against the end of the output rod 18, and the positioning piece adjustment member 19 is arranged on the top of the clamp body 14.

[0039] The roller follower 17 is arranged on the output rod 18 and is located below the end of the output rod 18; below the roller follower 17 is the wedge-shaped inclined surface of the wedge-shaped clamping block 13, and the wedge-shaped inclined surface of the wedge-shaped clamping block 13 contacts the roller follower 17. The compression spring fixing piece 15 is opened downward and is arranged on the top of the clamp body 14, and the compression spring 16 is arranged inside the compression spring fixing piece 15. The output rod 18 is rotatably connected to the clamp body 14 through the rotating shaft 110.

[0040] After the output cylinder 11 starts working, the output shaft can drive the floating joint 12 to push forward and retract, and the wedge-shaped clamping block 13 moves forward and backward accordingly, and the stressed output rod 18 can rotate around the rotating shaft 110.

[0041] The automatic rotating shaft base 2 includes a fixture mounting plate 21, a pressed product component mounting piece 22, a rotating A-axis 23 and a rotating B-axis 24; the rotating B-axis 24 is arranged horizontally, the rotating A-axis 23 is arranged vertically and installed on the rotating B-axis 24, and the fixture mounting plate 21 is installed horizontally on the top of the rotating A-axis 23; the fixture body component 1 is installed on the top of the fixture mounting plate 21, and the pressed product component mounting piece 22 is arranged on the rear side of the rotating B-axis 24.

[0042] The rotating A-axis 23 can rotate 360 ​​degrees in the horizontal direction, that is, the rotating A-axis 23 controls the horizontal rotation movement of the fixture mounting plate 21 .

[0043] The central axis of the rotating B axis is horizontal and transverse, and the rotating B axis 24 can only rotate around its central axis in the vertical direction at a certain angle, and the pressed product component mounting part 22 thereon tilts accordingly, that is, the rotating B axis 24 controls the tilting movement of this embodiment.

[0044] Since the clamp body component 1 is installed on the clamp mounting plate 21, and the clamp mounting plate 21 is installed on the rotating A-axis 23, and the rotating A-axis 23 is installed on the rotating B-axis 24, the clamp body component 1 can rotate 360 ​​degrees in the horizontal direction with the rotating A-axis 23, and can also tilt with the rotating B-axis 24.

[0045] The specific working process of the clamp body component 1 is as follows: when the output cylinder 11 outputs power, the output shaft moves forward and drives the floating joint 12 to move forward together. Since the dynamic floating joint 12 is connected to the wedge clamping block 13, the wedge clamping block 13 is pushed forward accordingly, and the inclined surface on the wedge clamping block 13 that moves forward will push the roller follower 17 upward, and the roller follower 17 is set on the output rod 18, so the output rod 18 rotates upward around the rotating shaft 110. When the output shaft of the output cylinder 11 retracts, the floating joint 12 retracts backward accordingly, and the wedge clamping block 13 also retracts backward, that is, the inclined surface of the wedge clamping block 13 moves backward, and the compression spring 16 pushes the output rod 18 downward to rotate reversely and return to the initial state.

[0046] The pressed product component 4 is mounted on the pressed product component mounting piece 22 . An arc-shaped adjusting groove 25 is formed on the top of the pressed product component mounting piece 22 . The bottom of the pressed product component 4 is slidably connected to the adjusting groove 25 .

[0047] The pressing product component 4 includes a force cylinder 41, a cylinder mounting plate 42, a second floating joint 43, a second wedge clamping block 44, a pressing body 45, a rotating cylinder 46, a fisheye bearing 47, a second roller follower 48, a second rotating shaft 410 and a second output rod 49.

[0048] The rotating cylinder 46 is arranged horizontally, and the output shaft of the rotating cylinder 46 is fixedly connected to the fisheye bearing 47. The output rod 49 is installed on the pressing body 45 through the rotating shaft 410, and the fisheye bearing 47 is connected to the top of the output rod 49; a roller follower 48 is provided at the inner end of the output rod 49, and the cylinder mounting plate 42 is vertically installed on the bottom inner wall of the pressing body 45, and the force cylinder 41 is fixedly installed on the outer wall of the cylinder mounting plate 42.

[0049] The rotating cylinder 46 is hinged on the pressing body 45; the output shaft of the forcing cylinder 41 is arranged horizontally inward, and the output shaft of the forcing cylinder 41 is fixedly connected with a floating joint 43, and the other end of the floating joint 43 is fixedly connected with a wedge clamping block 44; the wedge clamping block 44 is arranged inside the pressing body 45, and the inclined surface of the wedge clamping block 44 can contact with the roller follower 48 when subjected to thrust, and the two are separated and do not contact each other when not subjected to thrust.

[0050] The fixture parts 3 include a side pressure head 7, a positioning piece 9 and an upper pressure head 10; the side pressure head 7 is installed on the output rod 18, the positioning piece 9 is installed on the upper top surface of the fixture body 14, the positioning piece adjustment part 19 is fixed on the periphery of the positioning piece 9, and the upper pressure head 10 is installed on the outer arm of the output rod 2 49.

[0051] The positioning piece 9 is installed on the fixture body 14, and is used to place the blade 8 and provide a positioning surface for the blade 8. The side pressure head 7 is installed on the output rod 18 of the fixture body part 1, which can provide a clamping force to the blade 8 from the side, which can provide a lateral thrust to make the blade 8 close to the positioning piece 9, and can also clamp the blade 8 from the side. That is, the fixture body part 1 can not only be used to fix the jig parts 3 and place the blade 8, but also be used to provide clamping action and clamping force, so that the blade 8 can be positioned and clamped on the fixture body part 1. Because the fixture body part 1 can rotate with the rotating A axis 23 and the rotating B axis 24, the blade 8 fixed to the fixture body part 1 can also rotate with the rotating A axis 23 and the rotating B axis 24.

[0052] The positioning piece 9 can be designed as an integrated structure or a split structure according to actual conditions. The positioning piece 9 in this embodiment is designed as an integrated structure.

[0053] The upper pressing head 10 is installed on the output rod 2 49 of the pressed product component 4, and is used to pre-clamp, clamp or release the blade 8. By setting the pressed product component 4, the rotary cylinder 46 can control the output rod 2 49 to rotate, thereby driving the upper pressing head 10 to pre-clamp or release the blade 8, and the force cylinder 41 can push the wedge-shaped clamping block 2 44, and output the clamping force to the upper pressing head 10 through the output rod 2 49, thereby clamping the blade 8.

[0054] When the output cylinder 11 of the clamp body 1 outputs power, the output shaft is pushed forward, and the wedge clamping block 13 is pushed forward accordingly. The inclined surface of the wedge clamping block 13 can make the output rod 18 rotate upward around the rotating shaft 110. The output rod 18 rotating upward can provide a pressing force for the side pressure head 7, so the side pressure head 7 clamps the blade 8. When the output shaft of the output cylinder 11 retracts, the compression spring 16 presses on the end of the output rod 18. At this time, the output rod 18 is subjected to the downward elastic force of the compression spring 16, and the output rod 18 rotates back and returns to the initial state. This set of actions realizes the side push and opening of the blade 8, thereby positioning and clamping the blade 8 laterally.

[0055] The output shaft of the rotary cylinder 46 in the pressed product component 4 is connected to a fisheye bearing 47, and the fisheye bearing 47 is connected to the top of the output rod 2 (49), that is, the telescopic movement of the output shaft of the rotary cylinder 46 will affect the movement of the output rod 2 (49), so when the output shaft of the rotary cylinder 46 performs a telescopic movement, the output rod 2 49 can rotate around the rotating shaft 2 410, thereby controlling the upper pressing head 10 to press or release the blade 8. On the other hand, since the output shaft of the booster cylinder 41 is fixedly connected to a floating joint 43, the other end of the floating joint 43 is connected to a wedge-shaped clamping block 44, the wedge-shaped clamping block 44 can move forward and backward with the extension and retraction of the output shaft of the booster cylinder 41, and the inclined surface of the wedge-shaped clamping block 44 is in contact with a roller follower 48, and the roller follower 48 is connected to the inner end of the output rod 49. Therefore, the booster cylinder 41 can also control the upper pressure head 10 through the output rod 49, and can control the upper pressure head 10 to apply a strong pressure to the blade 8 to press the blade 8.

[0056] The pressed product component 4 is mounted on the pressed product component mounting member 22, and the pressed product component 4 can slide in the arc-shaped adjustment groove 25 on the pressed product component mounting member 22, that is, the pressed product component 4 can be adjusted in an arc-shaped position. In addition, since the pressed product component mounting member 22 can make an inclined movement with the rotating B axis 24, the pressed product component 4 can also make an inclined movement with the rotating B axis 24, but cannot rotate with the rotating A axis 23. When the clamp body component 1 and the blade 8 rotate with the rotating A axis 23, the pressed product component 4 does not move, and the upper press head 10 needs to release the blade 8.

[0057] The rotation A axis 23 and the rotation B axis 24 control the rotation movement and the tilt movement, respectively.

[0058] The A-axis 23 can rotate 360 ​​degrees in the horizontal direction, that is, rotating the A-axis 23 can provide a sufficient rotation range for the fixture body component 1 and the blade 8, thereby ensuring comprehensive grinding.

[0059] That is, through the cooperation of rotating A-axis 23 and rotating B-axis 24, precise control of the rotation and tilt of this embodiment can be achieved. The automatic rotating axis base 2 can control the angular rotation of the blade 8 in two different directions, thereby ensuring that the blade 8 can be ground with high quality at various positions, greatly improving the flexibility and accuracy of grinding.

[0060] The tilting of the rotating B-axis 24 can not only drive the fixture body part 1 to tilt, but also drive the pressed product part 4 to tilt. The pressed product part 4 itself can make arc position adjustments, which can not only provide more angle ranges for grinding, but also make the clamping positioning meet more usage scenarios, and the positioning of the blade 8 is more stable. The pressed product part 4 provides a downward positioning function, and can make corresponding adjustments according to the position changes of the blade 8. The downward positioning function provided at any time greatly improves the grinding accuracy of the blade. In the past, the accuracy was difficult to stabilize within ±0.05mm, while the accuracy of the blade produced in this embodiment can be stabilized within the range of ±0.01mm. The addition of the positioning function provides assistance for the stable clamping of the blade 8, so that this embodiment can produce more types of blades; such blades with back angles are positioned and clamped, and then they can be processed to produce high-precision blades with back angles on the periphery.

[0061] In this embodiment, the coordination of the fixture body part 1, the automatic rotating shaft base 2, the jig parts 3 and the pressed product parts 4 provides great convenience for material placement, positioning and clamping, detection and various grinding operations. Whether it is a complex blade 8 shape or a high-precision processing requirement, it can be met through precise angle adjustment.

[0062] like Figure 1 As shown, the rear positioning component 6 is installed at a specific position of the equipment, and the rear positioning component 6 can apply a thrust to the blade 8 from the front to the back. For different equipment, the installation position of the rear positioning component 6 will be different, and a reasonable position can be selected to install the rear positioning component 6 according to the actual situation. As long as the function of rear positioning can be implemented and interference can be avoided, there is no limitation. The design form of the rear positioning component 6 is not fixed, and it can be designed as a cylinder, or it can be designed as a mechanical arm and the like. As long as a thrust force can be output, there is no limitation on the design form. Whether to use the rear positioning component 6 is determined according to the positioning requirements of the blade 8. The grinding of some blades 8 requires the rear positioning component 6 to assist in positioning, and the grinding of some blades 8 does not require the rear positioning component 6 to assist in positioning.

[0063] In this embodiment, a rear positioning component 6 is provided, and the rear positioning component 6 is designed as a cylinder.

[0064] The air blowing component 5 is an independent unit, and the air blowing component 5 is slidably connected to the adjusting groove 25 . The air blowing component 5 can slide on the adjusting groove 25 to adjust its position.

[0065] The air blowing component 5 is used to blow air toward the blade 8, so as to blow away the attached liquid and impurities. The air blowing component 5 may be used or not according to the actual product processing needs.

[0066] The working principle and use process of this embodiment:

[0067] Install this embodiment in place, ensure that all parts are firmly connected, install the rear positioning component 6 at a certain part of the equipment to provide a pushing force from front to back for the blade 8, place the blade 8 on the top of the clamp body component 1, and use the positioning piece 9 to position the blade 8 to ensure the repeatable positioning accuracy of the blade 8.

[0068] The angle of the fixture body component 1 can be adjusted by rotating the A-axis 23 and the B-axis 24 to meet the needs of different grinding positions. The output cylinder 11 is started to push the floating joint 12 and the wedge-shaped clamping block 13 to move forward. The inclined surface of the wedge-shaped clamping block 13 drives the output rod 18 to rotate around the rotating shaft 110, thereby driving the side pressure head 7 to clamp the blade 8; at the same time, the force cylinder 41 of the pressed product component 4 pushes the floating joint 2 43 and the wedge-shaped clamping block 2 44 to output the clamping force to the upper pressure head 10, and the rotating cylinder 46 can also apply force to the upper pressure head 10, thereby clamping the blade 8 from above. According to needs, the angles of the fixture and the blade 8 can be adjusted by rotating the A-axis 23 and the B-axis 24 to achieve grinding at different positions.

[0069] During the grinding process, the blowing component 5 can blow air toward the blade 8 to blow away the attached liquid and impurities to ensure the grinding quality. After the grinding is completed, the output cylinder 11 is released, and the compression spring 16 pushes the output rod back to its original position. The side pressure head 7 releases the blade 8, the force cylinder 41 and the rotating cylinder 46 are also released, and the upper pressure head 10 releases the blade 8. The angle of the fixture is adjusted by rotating the A axis 23 and the rotating B axis 24 to facilitate the removal of the ground blade 8. Repeat the above steps to perform the next round of blade 8 grinding operation.

[0072] Embodiment 3
