[0002] With the continuous development of society, CNC machining has been widely used. Various CNC equipment is involved in the CNC machining process, among which the gripper is an auxiliary device. The function of the gripper is typically to place the part to be machined or the already machined part onto the machining table or to remove it from the machining table.

[0003] The shortcomings of existing technology:

[0004] Most CNC machine tool grippers are currently installed using bolts or screws, which usually require tools (such as wrenches, screwdrivers, etc.) for tightening. This process is relatively cumbersome, especially when the machine tool space is small, making operation even more difficult. Utility Model Content

[0005] The purpose of this invention is to provide a CNC machine tool gripper to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool gripper, comprising a gripping fixture and two quick-release mechanisms for rapid assembly and disassembly. Anti-detachment mechanisms are fixedly connected to both sides of the bottom of the gripping fixture. The two quick-release mechanisms include:

[0007] Two telescopic plates are welded to the top sides of the material gripping fixture;

[0008] Multiple telescopic rods are respectively installed inside two telescopic plates;

[0009] Multiple springs, each spring being sleeved on the surface of a multiple telescopic rod, are used to reset the telescopic plate;

[0010] Two control levers are respectively located on the front of the telescopic plate;

[0011] Two limiting blocks are respectively inserted into the two telescopic plates on the side away from the central axis of the material gripper to limit and fix the material gripper.

[0012] Preferably, the two anti-detachment mechanisms include:

[0013] Two clamping plates are provided on both sides of the bottom of the material gripping fixture;

[0014] Two airbags are fixedly connected to the side of the clamping plate near the central axis of the material gripper;

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This CNC machine tool gripper has two quick-release mechanisms, including a telescopic plate, a telescopic rod, springs, a control rod, and a limit block. Pulling the control rod shortens the telescopic plate, aligning one side of the telescopic plate with the slot in the limit block. Releasing the control rod causes the telescopic plate to reset and engage with the limit block under the reverse squeezing force provided by multiple springs, thus fixing the gripper. This facilitates quick and easy installation and removal of the gripper without the need for any tools, improving its practicality.

[0024] 2. This CNC machine tool gripper has two anti-slip mechanisms, including clamping plates, air bladders, silicone sleeves, and anti-slip blocks. After the gripper is activated, the two anti-slip mechanisms move closer to the central axis of the gripper. The two anti-slip blocks in the gripper ensure that the material does not slip during the gripping process. The two air bladders provide gas cushioning to prevent excessive impact or sudden intense pressure when the gripper clamps the material. The two silicone sleeves, as part of the gripper, further enhance the anti-slip performance between the gripper and the material, ensuring that the material is not easily displaced during processing, reducing processing errors caused by unstable clamping, and improving processing accuracy.

[0034] Example 1

[0035] Please see Figure 1-4 As shown, the CNC machine tool gripper technical solution provided by this utility model includes a gripping fixture 1 and two quick-release mechanisms 2 for rapid assembly and disassembly. Anti-detachment mechanisms 3 are fixedly connected to both sides of the bottom of the gripping fixture 1. The two quick-release mechanisms 2 include: two telescopic plates 201 welded to the top sides of the gripping fixture 1; multiple telescopic rods 202 respectively disposed inside the two telescopic plates 201; multiple springs 203 respectively sleeved on the surface of the multiple telescopic rods 202 for resetting the telescopic plates 201; two control rods 204 respectively disposed on the front of the telescopic plates 201; and two limiting blocks. 205. Two limiting blocks 205 are respectively inserted into the two telescopic plates 201 on the side away from the central axis of the gripping clamp 1 to limit and fix the gripping clamp 1. Pulling the control rod 204 shortens the telescopic plate 201, thereby aligning one side of the telescopic plate 201 with the slot opened in the limiting block 205. Releasing the control rod 204, under the reverse squeezing force provided by multiple springs 203, causes the telescopic plate 201 to reset and engage with the limiting block 205, thus fixing the gripping clamp 1. When disassembly is required, pulling the control rod 204 shortens the telescopic plate 201 and separates it from the limiting block 205, so that the gripping clamp 1 can be disassembled. This facilitates quick installation and disassembly of the gripping clamp 1 without the need for any tools, improving its practicality.

[0036] The two anti-slip mechanisms 3 include: two clamping plates 301, which are disposed on both sides of the bottom of the material gripping fixture 1; two airbags 302, which are fixedly connected to the clamping plates 301 on the side near the central axis of the material gripping fixture 1; two silicone sleeves 303, which are respectively fixedly connected to the surfaces of the two airbags 302 to increase anti-slip performance; and two anti-slip blocks 304, which are disposed on the side of the silicone sleeves 303 near the central axis of the material gripping fixture 1. The function of the two anti-slip blocks 304 in the material gripping fixture 1 is to ensure that the material does not slip during the gripping process. The function of the two airbags 302 is to provide gas cushioning to ensure that when the material gripping fixture 1 clamps the material, it will not cause excessive impact force or instantaneous violent pressure. The two silicone sleeves 303, as part of the two silicone sleeves 303, can further enhance the anti-slip performance between the material gripping fixture 1 and the material, making it easier to ensure that the material is not easily displaced during processing, reducing processing errors caused by unstable gripping, and improving processing accuracy.

[0037] Both silicone sleeves 303 have connecting blocks 4 fixedly connected to their front sides. Both connecting blocks 4 have quick-release bolts 5 threadedly connected to their surfaces. By rotating the quick-release bolts 5 until they pass through the connecting blocks 4 and into the threaded holes 6, the anti-detachment mechanism 3 can be fixed. This allows for selective installation of the anti-detachment mechanism 3 according to the material conditions.

[0038] Both clamping plates 301 have threaded holes 6 on their front sides. The threaded holes 6 are coated with epoxy resin anti-rust paint, which gives them excellent adhesion, corrosion resistance and wear resistance.

[0039] The top of each of the two limit blocks 205 is fixedly connected to a receiving block 7, and the surfaces of the two receiving blocks 7 are threaded with screws 8. The iron plate 9 is clamped to the quick-installation and disassembly mechanism 2 by the screws 8, which increases the stability of the quick-installation and disassembly mechanism 2.

[0040] Iron sheets 9 are fixedly connected to the front of the material gripper 1 on all four sides. Magnets 10 are magnetically connected to the front of the iron sheets 9. The back of the magnets 10 is attached to the front of the iron sheets 9 to generate magnetic properties and fix the storage plate 11 to the front of the material gripper 1 for use.

[0041] A storage plate 11 is provided on the front of multiple magnets 10. An acrylic transparent plate 12 is provided on the front of the storage plate 11. Safety reminders are placed inside the storage plate 11 and viewed through the acrylic transparent plate 12, which helps to reduce errors by inexperienced operators.

[0042] In this device, rotating the quick-release bolt 5 until it passes through the connecting block 4 and enters the threaded hole 6 will fix the anti-detachment mechanism 3. Then, pulling the control lever 204 will shorten the telescopic plate 201, aligning one side of the telescopic plate 201 with the slot in the limiting block 205. Releasing the control lever 204, under the reverse compressive force provided by multiple springs 203, will reset the telescopic plate 201 and engage with the limiting block 205, fixing the material gripper 1. This facilitates quick and easy installation and removal of the material gripper 1 without the need for any tools, improving practicality. Furthermore, after activating the material gripper 1, the two anti-detachment mechanisms... The structure 3 moves closer to the central axis of the gripping fixture 1. The two anti-slip blocks 304 in the gripping fixture 1 ensure that the material does not slip during the gripping process. The two airbags 302 provide gas cushioning to ensure that when the gripping fixture 1 clamps the material, it will not cause excessive impact or instantaneous violent pressure. The two silicone sleeves 303, as part of the two silicone sleeves 303, can further enhance the anti-slip performance between the gripping fixture 1 and the material, making it easier to ensure that the material is not easily displaced during processing, reducing processing errors caused by unstable clamping, and improving processing accuracy.
