Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for centerless grinders, and in particular to a connection mechanism based on a centerless grinder. Background Technology

[0002] The existing centerless grinding process includes three actions: feeding, grinding, and unloading. Generally speaking, the bar stock needs to go through multiple grinding processes on the centerless grinding machine to gradually reach the final requirements. In other words, the bar stock needs to be processed by multiple centerless grinding machines.

[0003] A search revealed Chinese Patent Publication No. CN221603971U, which discloses a connection mechanism for a centerless grinder. The mechanism includes a fixed base plate with an adjustable lifting assembly at its bottom and a material-guiding protective assembly at its top. The lifting assembly includes a supporting base plate at the bottom of the fixed base plate, with a slidable sliding structure at its top. The protective assembly includes an arc-shaped guard plate at the top of the fixed base plate, with a protective structure on its outer wall. This technical solution, in use, only adjusts the vertical height of the conveying mechanism through the lifting assembly, making it unsuitable for interfaces between two grinders with different heights. It also fails to adapt to complex connection scenarios caused by uneven workshop floors or mixed grinder models, resulting in poor practical application flexibility. Therefore, a connection mechanism based on a centerless grinder is provided to solve these problems. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0028] Reference Figures 1 to 5 In this embodiment of the utility model, a connecting mechanism based on a centerless grinder includes:

[0029] Angle adjustment mechanism 1 is used to adjust the overall height and tilt angle of the connecting mechanism. Angle adjustment mechanism 1 includes a support base plate 11. Four sets of movable universal wheels 12 are fixedly connected to the bottom of the support base plate 11. Two sets of first rotating seats 13 and guide fixed seats 14 are symmetrically fixedly connected to the top of the support base plate 11.

[0030] Auxiliary support mechanism 2 is provided above the angle adjustment mechanism 1. Auxiliary support mechanism 2 is used to reinforce the stability of the connecting mechanism after it is tilted by the angle adjustment mechanism 1.

[0031] Grinding machine connecting mechanism 3 is set above angle adjustment mechanism 1. Grinding machine connecting mechanism 3 is used for material transfer between centerless grinder and other mechanisms.

[0032] A long threaded rod 15 is rotatably connected to the inner side of the guide fixing seat 14, and a hand crank 16 is rotatably connected to the outer side of the guide fixing seat 14. An upper slider 17 is provided above the guide fixing seat 14. The rotating shaft end of the hand crank 16 passes through the guide fixing seat 14 and is fixedly connected to the long threaded rod 15. A slot adapted to the upper part of the guide fixing seat 14 is provided below the upper slider 17. The upper slider 17 is slidably connected above the guide fixing seat 14. A threaded hole adapted to the hand crank 16 is opened on the inner side of the upper slider 17. A first rotating arm 18 is rotatably connected to the inner side of the first rotating seat 13. A second rotating arm 19 is rotatably connected to the outer side of the upper slider 17. The two ends of the second rotating arm 19 are rotatably connected to the second rotating seat 110 and the outer side of the upper slider 17, respectively. The inner side of the second rotating arm 19 is rotatably connected to one end of the first rotating arm 18. A second rotating seat 110 is rotatably connected above the second rotating arm 19.

[0033] Using the above scheme: rotating the hand crank 16 drives the long threaded rod 15 to rotate, which engages with the threaded hole of the upper slider 17 to drive the upper slider 17 to move horizontally along the slot of the guide fixed seat 14. The upper slider 17 pushes the second rotating arm 19, which in turn drives the first rotating arm 18 to rotate around the first rotating seat 13, thereby driving the second rotating seat 110 to rise and fall, and finally adjusting the height and tilt angle of the support platform 31.

[0034] The auxiliary support mechanism 2 includes a third rotating seat 21. An upper hollow tube 22 is rotatably connected to the lower part of the third rotating seat 21. Several sets of trapezoidal external threaded blocks 23 are fixedly connected in a ring at equal intervals below the upper hollow tube 22. An internal threaded ring 24 is provided on the outer side of the trapezoidal external threaded block 23. The inner side of the trapezoidal external threaded block 23 gradually thickens from top to bottom. An internal thread is provided on the inner side of the internal threaded ring 24. An external thread that matches the internal threaded ring 24 is provided on the outer side of the trapezoidal external threaded block 23. A stop block is fixedly connected to the outer side of the internal threaded ring 24 for easy turning. An adjusting rod 25 is slidably connected to the inner cavity of the upper hollow tube 22. A fourth rotating seat 26 is rotatably connected below the adjusting rod 25.

[0035] Using the above scheme: Rotate the internal threaded ring 24, and through its internal thread engaging with the external thread of the trapezoidal external threaded block 23, the internal threaded ring 24 moves downward along the conical surface of the trapezoidal external threaded block 23, squeezing the trapezoidal external threaded block 23 to radially contract and clamp the adjusting rod 25. When the internal threaded ring 24 is released, the trapezoidal external threaded block 23 elastically recovers and releases the locking force. The adjusting rod 25 can slide and extend within the upper hollow tube 22. The fourth rotating seat 26 is grounded and supported, forming a rigid support with adjustable height.

[0036] The grinding machine connection mechanism 3 includes a support platform 31, a conveyor belt 32 is provided on the inner side of the support platform 31, and a feeding baffle 33 is fixedly connected at equal intervals on the belt surface on the outer side of the conveyor belt 32. The second rotating seat 110 and the third rotating seat 21 are both fixedly connected below the support platform 31, and the first rotating seat 13 and the fourth rotating seat 26 are both fixedly connected above the support base plate 11.

[0037] The above scheme is adopted: the support platform 31 is hinged to the angle adjustment mechanism 1 through the second rotating seat 110 to realize the tilt angle adjustment, and the support force is transmitted through the third rotating seat 21 hinged to the auxiliary support mechanism 2. When the conveyor belt 32 is running, the equidistantly distributed feeding baffles 33 can push the workpiece to move in an directional manner along the surface of the support platform 31, and can also prevent the material from shifting or stacking when the conveyor belt 32 has a certain tilt angle. The fourth rotating seat 26 fixes the grounding end of the auxiliary support mechanism 2, and the first rotating seat 13 fixes the rotation fulcrum of the angle adjustment mechanism 1.

[0038] The working principle of this utility model is as follows: First, the external thread of the trapezoidal external thread block 23 and the external spiral opening angle of the long thread rod 15 are 20 degrees, and the thread self-locking condition satisfies the following formula: self-locking condition = friction coefficient * tan (spiral angle) ≥ 1. The entire connecting mechanism is moved and positioned between the two centerless grinding machines to be connected by the four sets of movable universal wheels 12 under the support base plate 11. The hand cranks 16 on both sides are rotated to drive the long thread rod 15 fixedly connected to them to rotate. Through the meshing transmission with the threaded hole opened on the inner side of the upper slider 17, the upper slider 17 moves horizontally along the slot above the guide fixed seat 14. The upper slider 17 pushes the second rotating arm 19 rotatably connected to it, and at the same time, it links the first rotating arm 18 rotatably connected to the first rotating seat 13, thereby driving the second rotating seat 110 fixed above the second rotating arm 19 to perform lifting and lowering movements. Finally, the initial height of both ends of the support table 31 is adjusted to be close to the level of the interface of the two grinding machines, ensuring that the surface of the conveyor belt 32 can smoothly connect the discharge port of the front grinding machine and the feed port of the rear grinding machine.

[0039] At the same time, the adjusting rod 25 of the auxiliary support mechanism 2 slides out synchronously in the cavity of the upper hollow tube 22. After the two ends of the support table 31 are close to the horizontal of the two sets of grinding machine interfaces, the internal thread ring 24 is rotated. By using its internal thread to mesh with the external thread on the outside of the trapezoidal external thread block 23, the internal thread ring 24 is driven to move downward along the tapered surface that gradually thickens on the inside of the trapezoidal external thread block 23, thereby radially squeezing the trapezoidal external thread block 23 to make it shrink, hugging and locking the internal adjusting rod 25, forming a rigid auxiliary support, and reinforcing the stability requirements caused by the tilt of the support table 31.

[0040] Then, the conveyor belt 32 of the grinding machine connecting mechanism 3 is started. The feeding baffles 33, which are fixed at equal intervals on the outer belt surface of the conveyor belt 32, circulate in a cycle. After the workpiece is output from the previous centerless grinding machine, it falls into the support table 31 and is then pushed by the continuously moving feeding baffles 33 on the conveyor belt 32. It slides and is transported in a direction along the surface of the support table 31, which has a certain inclination angle. During this process, the feeding baffles 33 not only push the workpiece forward, but also effectively prevent the workpiece from shifting or stacking on the inclined conveyor belt 32, ensuring that the workpiece is transported to the feed port of the subsequent centerless grinding machine in an orderly and stable manner, thus completing the automated material transfer between the two grinding machines.

[0041] When it is necessary to adjust the position or retract the equipment, rotate the internal threaded ring 24 in the opposite direction to release its squeezing effect on the trapezoidal external threaded block 23, so that the trapezoidal external threaded block 23 can elastically recover and thus loosen the adjusting rod 25. At this time, the adjusting rod 25 can slide freely back into the upper hollow tube 22. Then, rotate the hand crank 16 in the opposite direction to drive the support platform 31 to return to the horizontal state through the four-bar linkage mechanism. Finally, use the movable universal wheel 12 to move the entire connecting mechanism away from the current work position or store it.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
