Description

Technical Field

[0001] This utility model relates to the field of alloy sample preparation technology, specifically to an end cap clamping and positioning device for alloy sample vibration. Background Technology

[0002] Alloys are substances with metallic properties formed by mixing two or more chemical substances (at least one of which is a metal). In the process of alloy sample preparation, a pulverizer is required. This is a machine that crushes large solid raw materials to the required size. It achieves the crushing purpose by high-speed impact and uses wind power to form powder in one step, eliminating the need for traditional screening procedures.

[0003] During the crushing process, a clamping mechanism is needed to press and limit the sealing cover to improve the stability of the connection between the sealing cover and the crushing chamber. This is a mechanical device that relies on the change in radius of an eccentric wheel during rotation to generate clamping force, directly or indirectly fixing the workpiece through the eccentric wheel or eccentric shaft. However, the crushing process generates significant vibrations, which can lead to the eccentric wheel loosening, thus affecting the stability of the sealing cover and posing a significant safety hazard. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides an end cap clamping and positioning device for alloy sample vibration, including a top plate 2 and a rotating shaft 6 rotatably connected to the top of the top plate 2. The rotating shaft 6 is connected to two eccentric wheels 13, which are distributed opposite to each other. A rotating rod 7 for driving the rotating shaft 6 is connected to the rotating shaft 6. An anti-slip sleeve is provided at the end of the rotating rod 7 to increase the friction with the hand and facilitate operation. A limiting mechanism for limiting the rotation rod 7 is connected to the top plate 2. An L-shaped plate 3 is connected to one side of the top of the top plate 2, and a pressing mechanism is connected to the L-shaped plate 3. An eccentric wheel 12 matching the pressing mechanism is connected at the midpoint of the rotating shaft 6.

[0024] After the sealing cover 1 is placed, the rotating rod 7 drives the rotating shaft 6 to rotate, which in turn drives the eccentric wheel 12 and the two eccentric wheels 13 to rotate. The eccentric wheel 12 drives the lifting plate 11 to descend, causing the two pressing blocks 20 to descend. When the rotating rod 7 is connected to the limiting mechanism, the rotating rod 7 is limited, improving the stability of the eccentric wheel 12 and the two eccentric wheels 13. The eccentric wheel 12 presses against the lifting plate 11, and the two pressing blocks 20 and the two eccentric wheels 13 press against the sealing cover 1, improving the stability of the sealing cover 1 and making the sealing cover 1 firmly and tightly connected to the crushing chamber.

[0025] The limiting mechanism includes a limiting seat 8, a baffle 16, a limiting groove 17, a pulling head 21, a connecting rod 22, a U-shaped frame 23, multiple springs 24, and a moving plate 25. The limiting seat 8 is connected to the top of the top plate 2. The limiting groove 17 is provided in the limiting seat 8 and matches the rotating rod 7. The baffle 16 is movably connected to the limiting seat 8. The U-shaped frame 23 is fixed to the side of the limiting seat 8. The moving plate 25 is movably connected to the U-shaped frame 23 and connected to the baffle 16. The two ends of the connecting rod 22 are connected to the pulling head 21 and the moving plate 25. The springs 24 are used to drive the moving plate 25 to move closer to the baffle 16.

[0026] During the rotation of the rotating rod 7, the rotating rod 7 slides relative to the baffle 16, causing the baffle 16 to move closer to the pulling head 21, simultaneously driving the moving plate 25, connecting rod 22, and pulling head 21 to move. At this time, the second spring 24 is gradually compressed. When the rotating rod 7 is connected to the limiting groove 17, the compressed second spring 24 drives the moving plate 25 and baffle 16 to return to their original positions. At this time, the bottom of the baffle 16 is connected to the rotating rod 7, thereby limiting the rotation rod 7 and preventing the eccentric wheel 12 and the two eccentric wheels 13 from becoming loose.

[0027] When loosening the rotating rod 7, a pulling force is applied to the pulling head 21, which in turn pulls the connecting rod 22, the moving plate 25, and the baffle 16 to move until the baffle 16 separates from the rotating rod 7, thus loosening the rotating rod 7. Finally, rotating the rotating rod 7 drives the rotating shaft 6 to rotate, simultaneously rotating the eccentric wheel 12 and the two eccentric wheels 13, facilitating the loosening of the sealing cover 1.

[0028] Spring 24 is fitted onto U-shaped frame 23 and connecting rod 22, and both ends of spring 24 are connected to moving plate 25 and U-shaped frame 23.

[0029] The top of the top plate 2 is connected to two guide seats 15. The rotating shaft 6 is rotatably connected to the guide seats 15 to improve the stability of the rotation of the rotating shaft 6. That is, the eccentric wheel 12 and the two eccentric wheels 13 rotate steadily. The end of the rotating rod 7 is connected to the rotating shaft 6.

[0030] The pressing mechanism includes a lifting plate 11, two guide pillars 18, two springs 19, and two pressing blocks 20. The guide pillars 18 guide the lifting plate 11, and the pressing blocks 20 are connected to the bottom of the lifting plate 11. The springs 19 are sleeved on the guide pillars 18, and both ends of the springs 19 are connected to the L-shaped plate 3 and the lifting plate 11. When the eccentric wheel 12 rotates, it drives the lifting plate 11 to descend, simultaneously driving the two guide pillars 18 to descend, providing good guidance for the lifting plate 11 and improving the stability of the movement of the two pressing blocks 20. At the same time, the springs 19 are gradually stretched. When the eccentric wheel 12 rotates a certain angle, the two pressing blocks 20 press against the sealing cover 1, improving the stability of the sealing cover 1.

[0031] When the eccentric wheel 12 rotates, the stretched spring 19 pulls the lifting plate 11 upward, which in turn drives the two pressing blocks 20 upward, causing the pressing blocks 20 to separate from the sealing cover 1, thereby loosening the sealing cover 1.

[0032] The guide post 18 is slidably connected to the L-shaped plate 3, and the bottom of the guide post 18 is connected to the lifting plate 11. A groove is provided at the top center of the lifting plate 11, and the groove is connected to the eccentric wheel 12. The groove has a curved surface structure, which increases the contact area with the sealing cover 1, thereby changing the harmful line contact into surface contact.

[0033] The inner side of the L-shaped plate 3 is connected to a limiting block 4. The bottom of the limiting block 4 is fixedly connected to the top plate 2, and the inner side of the limiting block 4 is provided with an arc-shaped surface 5, which is connected to the sealing cover 1. The side of the sealing cover 1 is connected to a handle 9. When installing the sealing cover 1, the handle 9 usually pushes the sealing cover 1 to the top of the crushing chamber until the sealing cover 1 is connected to the arc-shaped surface 5, which can achieve initial limiting of the sealing cover 1, so that the sealing cover 1 is in a suitable position and can completely cover the top of the crushing chamber.

[0034] When the sealing cap 1 is in the loosened state, apply a pulling force to the handle 9 to facilitate opening the sealing cap 1.

[0035] The top of the sealing cover 1 is connected to two connecting surfaces 14, which are connected to the eccentric wheel 13. The connecting surfaces 14 are also curved, thus changing the harmful line contact into surface contact.

[0036] Working principle: After the sealing cover 1 is placed, the rotating rod 7 drives the rotating shaft 6 to rotate, thereby rotating the eccentric wheel 12 and the two eccentric wheels 13. The eccentric wheel 12 drives the lifting plate 11 and the two pressing blocks 20 to move downwards, and the spring 19 is gradually stretched. The rotating rod 7 slides relative to the baffle 16, causing the baffle 16 to move closer to the pulling head 21, and the spring 24 is gradually compressed. Until the rotating rod 7 is connected to the limiting groove 17, the compressed spring 24 drives the baffle 16 to return to its original position. The bottom of the baffle 16 is connected to the rotating rod 7, thereby limiting the rotation shaft 6, the eccentric wheel 12, and the two eccentric wheels 13. At this time, the eccentric wheels 13 press against the sealing cover 1, and the two pressing blocks 20 also press against the sealing cover 1, improving the stability and tightness of the connection between the sealing cover 1 and the crushing chamber. When the sealing cover 1 needs to be opened, pull the pull head 21 to move the baffle 16, so that the baffle 16 is separated from the rotating rod 7. Then rotate the rotating rod 7 to drive the rotating shaft 6 to rotate, so that the eccentric wheel 12 and the two eccentric wheels 13 rotate. The eccentric wheels 13 are separated from the sealing cover 1. The stretched spring 19 pulls the lifting plate 11 and the two pressing blocks 20 to move upward. The pressing blocks 20 are separated from the sealing cover 1, so that the sealing cover 1 can be loosened and opened easily. The operation is simple and convenient.

[0037] The springs mentioned above are made of chromium-silicon steel, which has higher strength and resistance to tempering, and excellent fatigue resistance.
