For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Example

[0032] See also Figures 1 to 9 In the embodiment of the present invention, a hardness detection device for casting and forging processing includes an inspection seat 1, a support frame 2 is symmetrically installed on the upper end of the inspection seat 1, a connecting frame 5 is symmetrically installed on the upper end of the support frame 2, a connecting shaft 34 is rotatably installed between the lower ends of the connecting frame 5, a connecting cylinder 33 is fixedly installed in a direction perpendicular to the connecting shaft 34, a control frame 32 is rotatably installed inside the connecting cylinder 33, a detection mechanism is installed on the control frame 32, a fixing frame 6 is installed on the upper end of the support frame 2, and a control mechanism for controlling the angle of the control frame 32 is provided on the fixing frame 6. The control mechanism is used to change the inspection angle of the inspection mechanism in real time, which meets the hardness inspection needs at different angles and further improves the hardness inspection accuracy.

[0033] In order to perform real-time position change control on the inspection mechanism, in this embodiment, the control mechanism includes a rotating shaft 37 rotatably mounted on a fixed frame 6, a rotating frame 35 is symmetrically fixed perpendicular to the outer wall direction of the rotating shaft 37, rotating cylinders 36 are respectively mounted on both sides of the bottom of the rotating frame 35, and an active frame 31 is rotatably mounted inside the rotating cylinder 36. The control mechanism also includes a control component.

[0034] The control assembly includes a passive frame 30 vertically fixedly mounted on a control frame 32, control balls 40 are fixedly mounted at both ends of the active frame 31 and the passive frame 30, a control shell 39 is sleeved on the outer side of the control ball 40, and a control rod 29 is fixedly mounted between the control shells 39 in the vertical direction.

[0035] In addition, in order to further facilitate the staff to operate the control mechanism, in this embodiment, a control handle 38 is fixedly installed at a position perpendicular to the side wall of the active frame 31.

[0036] The working principle of the above control mechanism is: Figure 1 When it is necessary to change the front and rear tilt angle position of the control frame 32, the staff holds the control handle 38 to swing the front and rear position. At this time, under the rotation limit action of the rotating shaft 37, the rotating frame 35 will drive the active frame 31 to change the angle synchronously. Then, under the action of the control rod 29, the control ball 40 and the control shell 39, the control frame 32 changes the angle synchronously under the limiting action of the connecting tube 33, and finally realizes the front and rear position change of the entire inspection mechanism; when it is necessary to change the left and right tilt angle position of the control frame 32, the staff swings the upper and lower positions of the control handle 38, and then under the action of the rotating tube 36, the active frame 31 swings left and right synchronously. Then, under the action of the control rod 29, the control ball 40 and the control shell 39, the passive frame 30 drives the control frame 32 to change the same position under the limiting action of the connecting shaft 34 and the connecting tube 33. In addition, regardless of whether the front and rear tilt angle position of the inspection mechanism is changed or the left and right tilt angle position is changed, the magnitude of the change in the control handle 38 is proportionally replicated on the control frame 32, that is, the more obvious the position change of the control handle 38 is, the more obvious the change in the tilt angle position of the inspection mechanism installed on the control frame 32 is.

[0037] In one case of this embodiment, the inspection mechanism includes an inspection box 7 fixedly mounted on a control frame 32, a driving inclined column 23 is rotatably mounted on the upper end of the inspection box 7, an inspection inclined column 24 is provided at the bottom of the driving inclined column 23 in contact with an inclined surface 25, an inspection shaft 20 is fixedly mounted at the bottom of the inspection inclined column 24, and the bottom of the inspection shaft 20 passes through the inspection box 7 and is connected to an inspection instrument 21, and the inspection mechanism also includes a locking assembly.

[0038] Among them, the locking assembly includes a locking groove 26 arranged on the side wall of the inspection inclined column 24 and a locking strip 27 fixed on the inner side wall of the inspection box 7. The locking strip 27 is internally slidably arranged inside the locking groove 26, and an inspection spring 28 is also installed on the outside of the inspection shaft 20 between the bottom of the inspection inclined column 24 and the bottom side of the inspection box 7.

[0039] Furthermore, in order to effectively drive the inspection mechanism to work, an inspection motor 41 is also installed at the upper end of the inspection box 7 , and the output end of the inspection motor 41 is connected to the driving shaft 22 fixed to the upper end of the driving inclined column 23 .

[0040] The working principle of the above-mentioned inspection mechanism is: start the inspection motor 41, so that the driving shaft 22 drives the driving inclined column 23 to rotate synchronously. Since the inclined surface 25 is arranged on the common contact surface of the driving inclined column 23 and the inspection inclined column 24, and the movement direction of the inspection inclined column 24 is also limited by the positioning strip 27, the inspection inclined column 24 will only drive the inspection shaft 20 to move linearly up and down. Finally, under the resetting action of the inspection spring 28, the inspection instrument 21 moves up and down on the upper surface of the forging, thereby achieving the purpose of hardness detection. Example

[0041] Since the motion range of the tester 21 corresponding to the hardness test of castings and forgings of different thicknesses is different, the present invention also provides another embodiment, which is different from the above embodiment in that adjustment columns 3 are fixedly installed at the four corners of the upper end of the test seat 1, and an adjustment table 4 is fixedly installed on the adjustment column 3. An adjustment groove 11 is arranged inside the adjustment table 4, and an inspection table 8 is arranged inside the adjustment groove 11. An inspection groove 10 is arranged on the inspection table 8, and an adjustment mechanism for changing the upper and lower positions of the inspection table 8 is arranged on the adjustment table 4.

[0042] Among them, the adjustment mechanism includes a plurality of adjustment seats 13 fixedly installed at the upper edge position of the adjustment platform 4, a rotating shaft 14 is rotatably installed on the adjustment seat 13, a rotating disk 16 is fixedly installed at one end of the rotating shaft 14 close to the inspection slot 10, a rotating column 18 is fixedly installed at a non-center position of the end of the rotating disk 16, a rotating connecting rod 19 is hingedly installed on the rotating column 18, and the rotating connecting rod 19 is hingedly installed at the outer edge position of the inspection platform 8 at one end away from the rotating column 18. The adjustment mechanism also includes an adjustment component for driving the plurality of rotating shafts 14 to rotate synchronously.

[0043] In addition, the adjustment component includes an adjustment gear ring 12 rotatably installed at the upper edge of the adjustment platform 4, and the upper end of the adjustment gear ring 12 is meshed with multiple adjustment gears 15 fixed at one end of the outer side of the rotating shaft 14. The adjustment platform 4 is also equipped with a motor frame 17, and the motor frame 17 is equipped with an adjustment motor 9, and the output end of the adjustment motor 9 is connected to one of the rotating shafts 14.

[0044] The working principle of the above-mentioned adjustment mechanism is: start the adjustment motor 9, so that the rotating shaft 14 at the corresponding position rotates synchronously, and then drives the adjustment gear 15 at this position to rotate as well. Since the adjustment gear ring 12 rotates synchronously with multiple adjustment gears 15, the adjustment gears 15 at other positions will also rotate, and finally drive the rotating shaft 14 at other positions to rotate, and then make multiple rotating disks 16 rotate synchronously, and then with the cooperation of the rotating column 18 and the rotating connecting rod 19, the upper and lower positions of the inspection table 8 are quickly changed.

[0045] To sum up, in the hardness test process of castings and forgings, the castings and forgings are first placed inside the test slot 10 of the test table 8, and the adjustment motor 9 is started to adjust the position between the test table 8 and the tester 21. After the position adjustment is completed, the test motor 41 is started, and then under the action of the test mechanism, the tester 21 moves up and down and makes surface contact with the castings and forgings to obtain the corresponding hardness data. During this process, the staff can operate the control handle 38, and then under the action of the control mechanism, the contact inclination position of the tester 21 and the castings and forgings is changed in real time, thereby obtaining more accurate castings and forgings hardness data. The entire test process is quick and convenient.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
