Description

Technical Field

[0001] This utility model relates to the field of grinding fixture technology, and in particular to an adjustable pressure grinding fixture. Background Technology

[0002] Adjustable pressure grinding fixtures are flexible and adaptable tools widely used in the production, processing, and testing fields of industries such as machinery manufacturing, electronics, mold making, and aerospace. By adjusting the pressure of the fixture, efficient and precise grinding processing can be achieved on workpieces of different sizes and shapes.

[0003] Chinese Patent Publication No. CN220718942U discloses a FA end face grinding fixture, including a fixed base, a clamping mechanism, and an adjusting component. The fixed base has multiple side walls; each side wall is connected to a clamping mechanism, and a clamping space for clamping a target workpiece is formed between each clamping mechanism and its corresponding side wall. The adjusting component is connected to the clamping mechanism and is used to adjust the clamping space. By setting multiple clamping spaces in the FA end face grinding fixture, the FA end face grinding fixture can grind multiple FAs simultaneously in one go, thereby improving the grinding efficiency of FAs.

[0004] Although the equipment described in the above literature can clamp the workpiece during grinding, it cannot adjust the height and angle of the workpiece. During the grinding process, the relative position between the workpiece and the grinding surface may not reach the optimal state, which may result in an uneven surface of the workpiece after grinding, or over-grinding or under-grinding in some areas, thereby reducing the grinding accuracy. Utility Model Content

[0005] The main purpose of this invention is to provide an adjustable pressure grinding fixture, which can effectively solve the problem of not being able to adjust the height and angle of the workpiece.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-3 As shown, an adjustable pressure grinding fixture includes a base plate 1. Adjustment components 2 are fixedly connected to both sides of the upper end of the base plate 1. The upper ends of the two adjustment components 2 are fixedly connected to a housing 3. A cross slide groove 4 is opened on the upper side of the housing 3. A clamping component 5 is rotatably connected to the inner surface of the housing 3.

A lifting part 23 is rotatably connected to the upper side of the sliding groove 22. A housing 24 is provided on the outer side of the housing 21. Sliding blocks 25 are fixedly connected to the lower part of both side walls of the inner surface of the housing 24. Both sliding blocks 25 are slidably connected to the sliding groove 22.

[0027] like Figure 3 and Figure 5 As shown, the lifting part 23 includes a threaded rod 231 rotatably connected to the upper side of the housing 21. A fixing plate 232 is fixedly connected to the upper side of the outer surface of the threaded rod 231. A bevel gear 233 is fixedly connected to the upper end of the threaded rod 231. A bevel gear 234 is meshed on the upper side of the bevel gear 233. A rotating rod 235 is fixedly connected to the middle of the bevel gear 234. The fixing plate 232 is located on the lower side of the bevel gear 233 and is fixedly connected to the inner surface of the housing 24.

[0028] One end of the rotating rod 235 is rotatably connected to the inner surface of the housing 24, and the other end of the rotating rod 235 passes through the housing 24 and extends to the outside of the housing 24.

[0029] In actual use of the device, when it is necessary to adjust the height of the workpiece, the rotating rod 235 can be rotated. The rotating rod 235 drives the bevel gear 234 and bevel gear 233 to rotate, which in turn drives the threaded rod 231 to rotate and move in the vertical direction. When the threaded rod 231 moves, it drives the housing 24 and the box 3 to move through the fixed plate 232, thereby realizing the adjustment of the workpiece height.

[0030] like Figure 4 As shown, the clamping assembly 5 includes a base 51 disposed on the inner surface of the housing 3. Support plates 52 are fixedly connected to the four corners of the upper end of the base 51. Rotating plates 53 are rotatably connected to the upper sides of the four support plates 52. Connecting members 54 are rotatably connected to the upper sides of the four rotating plates 53. The four connecting members 54 are all L-shaped. Clamping plates 55 are fixedly connected to the upper ends of the four connecting members 54. A sliding part 56 is fixedly connected to the top wall of the inner surface of the housing 3.

[0031] All four clamping plates 55 are slidably connected within the cross groove 4.

[0032] like Figure 4As shown, the sliding part 56 includes a second box 561 fixedly connected to the top wall of the inner surface of the first box 3. Slide rails 562 are fixedly connected to all four sides of the upper end of the second box 561. Sliding sliders 563 are slidably connected to all four sides of the four slide rails 562. A threaded rod 565 is rotatably connected to the lower side of the second box 561. A motor 564 is fixedly connected to the bottom wall of the inner surface of the second box 561. The output end of the motor 564 is fixedly connected to the threaded rod 565 via a coupling. All four sliders 563 are fixedly connected to a connecting piece 54 that is close to each other.

[0033] The lower end of the threaded rod 565 passes through the base 51 and extends to the bottom wall of the inner surface of the housing 3. The threaded rod 565 is rotatably connected to the bottom wall of the inner surface of the housing 3.

[0034] In actual use of the device, the workpiece to be ground is placed in the middle of the upper part of the housing 3. The motor 564 drives the threaded rod 565 to rotate, thereby moving the base 51 upward. The upward movement of the base 51 causes the rotating plate 53 to rotate. The rotating plate 53 pushes the connecting piece 54 upward, and then the connecting piece 54 pushes the clamping plate 55 and the slider 563 to slide on the four sides of the slide rail 562, causing the four clamping plates 55 to move towards the workpiece, clamping and fixing the workpiece, and then subsequent grinding can be carried out.

[0035] It should be noted that the specific installation method, circuit connection method, and control method of the motor 564 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0036] The working principle of this utility model is as follows: First, the workpiece to be ground is placed in the middle of the upper end of the housing 3. The motor 564 drives the threaded rod 565 to rotate, thereby driving the base 51 to move upward. The upward movement of the base 51 drives the rotating plate 53 to rotate. The rotating plate 53 pushes the connecting piece 54 to move upward. Then, the connecting piece 54 pushes the clamping plate 55 and the slider 563 to slide on the four sides of the slide rail 562, driving the four clamping plates 55 to move towards the workpiece, clamping the workpiece and fixing it, and then subsequent grinding can be carried out.

[0037] When it is necessary to adjust the height of the workpiece, the rotating rod 235 can be rotated. The rotating rod 235 drives the bevel gear 234 and bevel gear 233 to rotate, which in turn drives the threaded rod 231 to rotate and move in the vertical direction. When the threaded rod 231 moves, it drives the housing 24 and the box 3 to move through the fixing plate 232, thereby realizing the adjustment of the workpiece height.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
