The CNC machine tool gripper can be installed more conveniently, can protect the parts to be gripped, and has a dustproof function that makes it easier to clean the device.

[0004] In response to the above-mentioned content, the inventor believes that the following technical defects exist: when using a CNC machine tool gripper to clamp parts with a relatively smooth surface and a round shape, the clamping stability is poor, and the parts will slip out of the clamping mouth of the CNC machine tool gripper, causing the parts to collide with the ground and cause damage to the surface of the parts. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art in that when clamping parts with relatively smooth and round surfaces, the clamping stability is poor, the parts may slip out of the clamping mouth of the CNC machine tool gripper, thereby causing the parts to collide with the ground and cause damage to the surface of the parts.

[0006] In order to solve the above technical problems, the utility model provides a CNC machine tool gripper, comprising: a clamp, a power device is installed on the inner wall of the clamp, and adjustment devices are provided on both sides of the clamp, and the adjustment device includes two fixed plates, and the two fixed plates are respectively fixedly connected to the two ends of the side of the clamp, and the two ends of the side surfaces away from each other are provided with adjustment grooves, and the inner wall of the adjusting groove is slidably connected to a connecting block, and the inner wall thread of the connecting block is threaded with a screw, and the screw is threadedly connected to the fixing plate, and the side of the screw connecting block away from the fixing plate is fixedly connected to a fixing rod, and the four fixing rods are fixedly connected to the same connecting block at one end close to the clamp.

[0007] The above-mentioned component achieves the effect that the part can be clamped by using the clamping opening, but when clamping the part with a smooth surface and in a circular shape, the stability of clamping is poor, the part can slip out of the clamping opening, resulting in the part colliding with the ground and causing damage to the part. The screw rod is connected with the connecting block, and then the screw rod is rotated to connect the screw rod with the fixed plate, so that the connecting block can be fixed in the adjusting groove. The connecting block is fixed, and the connecting block can be fixed on the clamping opening through the fixed rod. The connecting block can be used to clamp the part with a smooth surface, thereby improving the stability of clamping the part.

[0008] Preferably, the two abutment blocks are fixedly connected with connecting pads on the side close to each other, and the connecting pads are matched in size with the abutment blocks.

[0009] The above-mentioned component achieves the effect that when the abutment block is in contact with the part, the connecting pad installed on the abutment block can avoid the abutment block from causing extrusion damage to the surface of the part when the abutment block is in contact with the part, and the connecting pad can protect the surface of the part.

[0012] Preferably, the fixed rod is a titanium alloy rod.

[0013] The above-mentioned component achieves the effect that the titanium alloy rod has a relatively hard rod surface, and the surface of the fixed rod is less likely to deform after long-term use, thereby having a long service life.

[0015] The effect achieved by the above component is that workers are prone to get more grease liquid on fingers when working, and the rod of the power device is relatively short in design, and the hands are prone to slip between the power device when rotating the power device to drive the clamping opening to clamp the part, which makes the process of rotating the power device more difficult, and the instability of the clamping opening clamping the part is caused by the power device not rotating to the position, the connecting sleeve is connected with the fixed block, and then the adjusting block is used to rotate the adjusting plate, and the adjusting plate is connected with the limiting rod by rotation, so that the connecting sleeve is used to move the power device, thereby improving the effect of rotating the power device.

[0016] Preferably, the circular arc surface of the connecting sleeve is provided with a plurality of anti-skid grooves, and the plurality of anti-skid grooves are uniformly distributed on the circular arc surface of the connecting sleeve.

[0017] The effect achieved by the above component is that the anti-skid grooves provided on the connecting sleeve can improve the friction between the connecting sleeve and the hands, and improve the speed of rotating the connecting sleeve.

[0018] Preferably, the side of the fixed block away from the power device is fixedly connected with an auxiliary block, and the auxiliary block is in sliding connection with the connecting sleeve.

[0019] The effect achieved by the above component is that when the fixed block is connected with the connecting sleeve, the auxiliary block installed on the fixed block can improve the speed of connecting the connecting sleeve with the fixed block, and improve the efficiency of connecting the two.

[0020] Compared with the related art, the numerical control machine tool grabber has the following beneficial effects:

[0035] The working principle of the CNC machine tool gripper provided by the present invention is as follows: the clamping jaw 1 can be used to clamp the part, but when clamping a part with a relatively smooth surface and a round shape, the clamping stability is poor, and the part will slip out of the clamping jaw 1, causing the part to collide with the ground and cause damage to the part. The screw rod 24 is connected to the connecting block 22, and then the screw 24 is rotated to connect the screw 24 to the fixing plate 21, so that the connecting block 22 can be fixed in the adjusting groove 23. After the connecting block 22 is fixed, the connecting block 26 can be fixed to the clamping jaw 1 through the fixing rod 25, and the smooth surface part can be clamped by the connecting block 26.

The surface of the fixing rod 25 made of titanium alloy is relatively hard. After long-term use, the surface of the fixing rod 25 is also less likely to deform, and the service life is longer.

[0036] When workers are working, their fingers are easily contaminated with more grease and oil, and the rod of the power device 4 is designed to be short. When the power device 4 is rotated to drive the clamp 1 to clamp the parts, the hand and the power device 4 are easily slipped, which makes the process of rotating the power device 4 more difficult. If the power device 4 is not rotated in place, it will affect the stability of the clamp 1 in clamping the parts. Connect the connecting sleeve 32 with the fixed block 31, and then rotate the adjusting plate 34 through the adjusting block 33. When the rod 35 is connected, the power device 4 can be moved through the connecting sleeve 32, thereby improving the effect of rotating the power device 4. When the connecting sleeve 32 is rotated, the anti-slip groove 37 provided on the connecting sleeve 32 can increase the friction between the connecting sleeve 32 and the hand, thereby increasing the speed of rotating the connecting sleeve 32. When the fixing block 31 is used to connect with the connecting sleeve 32, the auxiliary block 36 installed on the fixing block 31 can increase the speed when the connecting sleeve 32 is connected to the fixing block 31, thereby improving the efficiency of the connection between the two.
