[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Example
[0025] See also Figure 1-4 The utility model provides the following technical solutions: an inductive metallographic grinding machine fixture, comprising an adjusting seat 1 and a base 6 fixed to one side of the adjusting seat 1, a movable clamping seat 2 is provided at the bottom of the adjusting seat 1, a clamping member 3 in multiple directions is provided on the clamping seat 2, the clamping seat 2 clamps the inductor through the clamping member 3, an adjusting member 4 for adjusting the distance between the clamping seat 2 and the adjusting seat 1 is provided between the adjusting seat 1 and the clamping seat 2, and a vernier caliper 5 for obtaining the adjustment distance of the adjusting member 4 is also provided between the adjusting member 4 and the adjusting seat 1.
[0026] Specifically, a nut 33 is fixed at one end of the screw rod 32, and a polygonal hole 35 is provided inside the polygonal sleeve 34 for the nut 33 to be inserted and slided. A through hole is also provided on the polygonal sleeve 34 for the screw rod 32 to pass through. In this embodiment, the locking drive is achieved by the elastic force of the locking spring 36, which has the advantages of simple structure and easy adjustment.
[0027] Specifically, the clamping component 3 includes an internal threaded sleeve 31 penetrating through the clamping seat 2 and a screw 32 threadedly connected to the internal threaded sleeve 31, and a polygonal sleeve 34 rotatably arranged on the outside of the clamping seat 2. The screw 32 can move in the polygonal sleeve 34. A locking spring 36 is provided between the outside of the clamping seat 2 and the polygonal sleeve 34. The locking spring 36 is fixedly installed with the clamping seat 2 and is rotatably connected to the polygonal sleeve 34. In this embodiment, the rotation between the locking spring 36 and the polygonal sleeve 34 is used to consume the rotational force between the polygonal sleeve 34 and the clamping seat 2, which can not only ensure the rotation of the polygonal sleeve 34, but also does not affect the plug-in locking of the tooth seat 37 and the toothed disc 38.
[0028] Specifically, a tooth seat 37 is fixedly provided on the outside of the clamping seat 2, and a toothed disc 38 is fixedly provided on the polygonal sleeve 34. The tooth seat 37 and the toothed disc 38 are connected by plugging together through a locking spring 36. In this embodiment, the rotation of the screw 32 can be limited by plugging together the tooth seat 37 and the toothed disc 38, thereby ensuring the reliability of the screw 32 in clamping the inductor.
[0029] Specifically, the adjusting component 4 includes a rectangular slider 41 fixed to the upper end of the clamping base 2 and sliding in the adjusting base 1, a threaded hole 42 opened in the adjusting base 1, an adjusting screw 43 threadedly connected to the threaded hole 42, and a handwheel 44 fixed on the top of the adjusting screw 43. In this embodiment, the adjusting component can be precisely adjusted according to the position and matching relationship between the inductor and the grinding surface, so as to better ensure the grinding accuracy.
[0030] Specifically, the bottom of the adjusting screw 43 rotates on the upper end of the rectangular slider 41, and the rectangular slider 41 and the clamping seat 2 are spirally displaced with the adjusting screw 43 through the threaded hole 42. In this embodiment, the driving of the adjusting screw 43 can also be driven by a servo motor, etc.
[0031] Specifically, the vernier caliper 5 includes an extension rod 51 vertically fixed on the top of the rectangular slider 41 and a pointer 52 fixed on the extension rod 51, as well as a movable groove 53 opened on the adjustment seat 1 and used for the pointer 52 to slide, and a scale 54 arranged on the outside of the adjustment seat 1 near the side of the movable groove 53. In this embodiment, the vernier caliper 5 can intuitively and accurately know the adjustment distance of the clamping seat 2 and the inductor, thereby improving the grinding accuracy.
[0032] The working principle and usage process of the present invention are as follows: the device is installed on the metallographic grinding machine through the base 6, the inductor to be clamped is placed on the lower part of the clamping seat 2, the polygonal sleeve 34 is pulled outward, the locking spring 36 is stretched, the toothed disc 38 and the tooth seat 37 are disengaged, and the polygonal sleeve 34 is rotated at this time. The polygonal sleeve 34 drives the screw rod 32 to rotate through the cooperation of the internal polygonal hole 35 and the nut 33. The screw rod 32 presses the inductor by the moving force generated by the spiral with the internal threaded sleeve 31. During the adjustment process, the nut 33 will also move inside the polygonal hole 35. After the inductor is clamped, the polygonal sleeve 34 is loosened, and the toothed disc 38 is engaged with the tooth seat 37 under the action of the locking spring 36. At this time, the polygonal sleeve 34 and the screw rod 32 are axially limited, and the screw rod 32 cannot rotate, thereby ensuring the stability of the screw rod 32 clamping the inductor.
[0033] To adjust the position, the hand wheel 44 is used to rotate the adjusting screw 43, and the rectangular slider 41, the clamping seat 2 and the clamped inductor are driven to move by the spiral between the adjusting screw 43 and the threaded hole 42. During the movement of the rectangular slider 41, the extension rod 51 drives the pointer 52 to slide in the movable groove 53, and the indicated position of the pointer 52 moves on the scale 54 until it is adjusted to the appropriate position.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
