[0002] A centerless grinder is a type of grinder that does not require workpiece axis positioning for grinding. It mainly consists of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. The grinding wheel is responsible for the actual grinding work, the adjusting wheel controls the rotation of the workpiece and the feed rate, and the workpiece support supports the workpiece during grinding. These three components can be combined in several ways, except when grinding is stopped, but the principle is the same.

[0003] Chinese Patent Publication No. CN222243911U discloses an automatic feeding and discharging centerless grinding machine, relating to the field of centerless grinding machine technology. The machine includes a grinding machine body, an internal discharge assembly, a mounting plate fixed to the side wall of the grinding machine body, a feeding assembly above the mounting plate, and a conveying frame. The feeding assembly includes a conveying frame, an internal first conveying wheel, a first conveyor belt sleeved on the outer wall of the first conveying wheel, a pusher fixed to the outer wall of the first conveyor belt, and a first motor on one side of the conveying frame.

[0004] However, the inventor of the above device believes that there are certain defects. The above device uses push blocks on the conveyor belt to push the workpiece to be transported between the grinding wheel and the adjusting wheel. Due to the lack of a directional mechanism, the end of the workpiece is prone to deviate and directly contact the grinding wheel or the adjusting wheel during the feeding process, which can easily cause damage to the end of the workpiece. Therefore, this utility model provides a directional clamping mechanism for feeding CNC grinding machines. Utility Model Content

The fixed seat is provided with a first adjustment mechanism for adjusting the included angle between the two directional plates. The clamping mechanism includes a support frame fixed to the grinding machine frame. An mounting frame is mounted on the inner top wall of the support frame. A pressure plate is fixedly connected inside the mounting frame, positioned between the grinding wheel and the adjusting wheel. The support frame is provided with a second adjustment mechanism for adjusting the mounting height of the mounting frame.

[0009] Preferably, the first adjustment mechanism includes first sliders mounted on both sides of the fixed base, with connecting rods rotatably connected to the first sliders. The other end of the connecting rod is hinged to one side of the directional plate. By controlling the two first sliders to move closer or further apart, the angle between the two directional plates is adjusted under the action of the connecting rod.

[0010] Preferably, the first adjustment mechanism further includes a first bidirectional screw rotatably connected to the fixed base, and the first slider is threadedly connected to the outer surface of the first bidirectional screw. Rotating the first slider drives the two first sliders to move closer to or further away from each other.

[0011] Preferably, the top of the fixed base is provided with multiple placement slots, and each of the multiple placement slots is rotatably connected with a roller. The rollers reduce the friction between the material and the top of the fixed base, so as to facilitate the feeding of the material between the grinding wheel and the adjusting wheel.

[0012] Preferably, the second adjustment mechanism includes a second slider that slides on the support frame, one end of the second slider is fixedly connected to a pressing rod, a fixing plate is fixedly connected to the top of the mounting frame, the fixing plate has an inclined groove, and the two ends of the pressing rod slide inside the two inclined grooves respectively.

[0015] This utility model provides a directional clamping mechanism for feeding CNC grinding machines, which has the following beneficial effects:

[0016] 1. This device uses two directional plates to quickly limit the workpiece to be ground, so that the workpiece is quickly and accurately fed between the grinding wheel and the adjusting wheel for grinding, reducing the damage to the end of the workpiece. The second adjustment mechanism places one end of the pressure plate on the top of the workpiece to prevent the workpiece from jumping to different degrees during the grinding process, which would affect the grinding quality of the workpiece.

[0017] 2. The device adjusts the angle between the two guide plates by means of the first bidirectional screw, the first slider and the connecting rod, so as to guide and limit workpieces of different sizes, and reduces the friction between the workpiece and the top of the fixed seat by means of the roller.

The entire device is a centerless grinding machine. A centerless grinding machine is a type of grinding machine that does not require workpiece axis positioning for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. The grinding wheel 11, the adjusting wheel 12, and the workpiece support 13 are existing technologies, and their working principles will not be described in detail in this application.

[0027] Please refer to it again. Figure 1 and Figure 2 The top of the grinding machine frame 1 is provided with an orientation mechanism 2 and a clamping mechanism 4. The orientation mechanism 2 includes a fixed seat 21 fixed to the feed end of the top of the grinding machine frame 1.

The top of the fixed seat 21 is provided with multiple placement slots. Rollers 22 are rotatably connected inside the multiple placement slots. The two orientation plates 3 are used to limit the workpiece to the left and right, so that the workpiece can be fed parallel between the grinding wheel 11 and the adjusting wheel 12, preventing the workpiece from being misaligned during feeding and causing damage to its end.

[0028] Please refer to it again. Figure 1 and Figure 3 The clamping mechanism 4 includes a support frame 41 fixed on the grinding machine frame 1. An mounting frame 51 is installed on the inner top wall of the support frame 41. A pressure plate 5 is fixedly connected inside the mounting frame 51. The pressure plate 5 is located between the grinding wheel 11 and the adjusting wheel 12. The bottom of the pressure plate 5 is placed on top of the workpiece to prevent the workpiece from jumping to different degrees during the grinding process.

[0029] Example 2;

[0030] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixed base 21 is provided with a first adjustment mechanism for adjusting the included angle between the two guide plates 3. The first adjustment mechanism includes a first slider 32 installed on both sides of the fixed base 21. A connecting rod 33 is rotatably connected to the first slider 32.

The first slider 32 is threaded to the outer surface of the first bidirectional screw 31. The first bidirectional screw 31 is a screw with two external threads. The threads of the two external threads are in opposite directions. By rotating the first bidirectional screw 31, the two first sliders 32 are controlled to move closer or further apart. Under the action of the connecting rod 33, the included angle between the two guide plates 3 is adjusted, thereby guiding workpieces of different sizes.

[0031] Example 3;

[0032] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The support frame 41 is provided with a second adjustment mechanism for adjusting the installation height of the mounting frame 51. The second adjustment mechanism includes a second slider 43 that slides on the support frame 41. One end of the second slider 43 is fixedly connected to a pressing rod 44. A fixed plate 52 is fixedly connected to the top of the mounting frame 51. An inclined groove 53 is provided on the fixed plate 52. The two ends of the pressing rod 44 slide inside the two inclined grooves 53 respectively. By driving the two second sliders 43 to move closer to each other, the pressing rod 44 at one end of the second slider 43 presses the inclined groove 53 on the fixed plate 52, thereby pushing the mounting frame 51 to descend and adjusting the height of the pressure plate 5. Conversely, the two second sliders 43 move away from each other, causing the mounting frame 51 to rise. The two sets of inclined grooves 53 are arranged in a V-shape.

[0033] Please refer to it again. Figure 1 , Figure 3 and Figure 4 The top of the support frame 41 is provided with a through groove, and a second bidirectional screw 42 is rotatably connected inside the through groove. Two second sliders 43 are threadedly connected to the second bidirectional screw 42 and slide inside the through groove. A handwheel is fixedly connected to one end of the second bidirectional screw 42, and plugs are fixedly connected to both ends of each extrusion rod 44. The second bidirectional screw 42 is a screw with two external threads, and the threads of the two external threads are opposite in direction. By rotating the handwheel at one end of the second bidirectional screw 42, it is easy to control the two second sliders 43 to slide closer to or further away from each other.

[0034] Working principle: The device is installed in a suitable position. According to the size of the workpiece, the first bidirectional screw 31 is rotated to move the two first sliders 32 closer or further apart. Under the action of the connecting rod 33, the included angle between the two guide plates 3 is adjusted. Then, the handwheel at one end of the second bidirectional screw 42 is rotated to control the two second sliders 43 to move closer or further apart. Under the action of the pressing rod 44 pressing the inclined groove 53, the mounting frame 51 is adjusted to rise and fall, thereby adjusting the installation height of the pressure plate 5. After adjustment, one end of the workpiece is placed on the top of the fixed seat 21. The two guide plates 3 quickly limit the workpiece to be ground, and under the action of the roller 22, the workpiece is quickly and accurately fed between the grinding wheel 11 and the adjusting wheel 12 for grinding. During the grinding process, one end of the pressure plate 5 is placed on the top of the workpiece to prevent the workpiece from jumping to different degrees during the grinding process.
