Description

Technical Field

[0001] This invention relates to the field of clamping devices, and particularly to a multifunctional CNC cutting machine clamp. Background Technology

[0002] A gripper is a device that holds and manipulates an object. It can grip and release an object while performing certain actions. Motion devices often mimic human movement; in the case of a gripper, it mimics the movement of the fingers. The "fingers" themselves are not part of the gripper; they are simply specialized, custom-made tools used to hold objects.

[0003] Existing clamps can hold and fix CNC cutting heads, but their use is limited. Sometimes, when CNC cutting requires cutting inclined surfaces, using a vertical method will affect the cutting quality and efficiency. It is necessary to rotate and fix the angle of the clamp. Therefore, a multi-functional CNC cutting machine clamp is needed. Summary of the Invention

[0004] The purpose of this application is to provide a multifunctional CNC cutting machine holder to solve the problem mentioned in the background art that the existing holders can only hold and fix the CNC cutting head, and their use is limited. Sometimes, when CNC cutting needs to cut inclined surfaces, if the vertical method is still used, it will affect the cutting quality and efficiency, and it is necessary to rotate and fix the angle.

[0005] To achieve the above objectives, this application provides the following technical solution: a multifunctional CNC cutting machine holder, comprising an upper connecting cylinder, a lower cutting cylinder disposed below the upper connecting cylinder, a cutting head threadedly connected to the bottom end of the lower cutting cylinder, an installation ring disposed on the surface of the cutting head, anti-slip pads disposed on the surfaces of both the upper connecting cylinder and the lower cutting cylinder, a positioning plate disposed at the rear of the upper connecting cylinder, an angle gauge disposed on the front of the positioning plate, and an angle adjustment mechanism disposed at the bottom end of the upper connecting cylinder.

[0006] The above structure, with the upper connecting cylinder and lower cutting cylinder, maintains the overall connection of the equipment. The installation ring facilitates the application of torque to the cutting head. When the cutting head is removed, anti-slip pads increase friction and prevent slippage on the surface. An angle instrument measures the rotation angle. A positioning plate fixes the device to an external object, ensuring stability. An angle adjustment mechanism provides a reference and positioning for the rotation angle, while preventing the cutting head from falling and impacting the object to be processed, thus preventing damage.

[0007] The angle adjustment mechanism includes a movable slide groove at the bottom of the upper connecting cylinder. A telescopic rod is mounted on the inner top wall of the movable slide groove. The bottom end of the telescopic rod is fixedly connected to the top end of the lower cutting cylinder. The surface of the lower cutting cylinder is slidably connected to the inner wall of the movable slide groove. A first return spring is sleeved on the surface of the telescopic rod. The top end of the first return spring is fixedly connected to the inner top wall of the movable slide groove, and the bottom end of the first return spring is fixedly connected to the top end of the lower cutting cylinder. By providing the movable slide groove, space is provided for the lower cutting cylinder to move and avoid impacts, preventing the cutting head from hitting the object being processed at a large depth and causing the lower cutting cylinder to bend and become unusable. By providing the telescopic rod, severe deformation of the first return spring is prevented. The first return spring helps the lower cutting cylinder return to its stable position.

[0008] Preferably, the inner wall of the positioning plate is rotatably connected to a connecting shaft, and one end of the connecting shaft is provided with a rotating disk.

[0009] Preferably, the surface of the rotating disk has a through hole, and the inner wall of the through hole is rotatably connected to a positive and negative lead screw.

[0010] Furthermore, by setting a connecting shaft, stable support for the rotating disk is maintained, and by setting a through hole, the installation of the positive and negative lead screws is avoided.

[0011] Preferably, one end of the positive and negative lead screw is provided with an operating knob, and the surface of the positive and negative lead screw is threaded with an arc-shaped clamp.

[0013] Furthermore, by setting an operating knob, the operator can rotate the operating knob to move the two arc-shaped clamps on the left and right closer or further apart. By setting the arc-shaped clamps, the surface of the lower cutting cylinder is clamped and fixed. By setting a positioning ring, the clamping position of the arc-shaped clamps is positioned.

[0014] Preferably, the surface of the connecting shaft is provided with an observation pointer, the surface of the connecting shaft is provided with multiple connecting strips, and the back of the positioning plate is provided with multiple guide positioning rods.

[0015] Furthermore, by setting an observation pointer, the angle instrument can easily determine the angle of rotation; by setting a connecting bar, the rotation of the connecting shaft drives the rotation of the connecting bar; and by setting a guide positioning rod, the movement of the moving block is guided and supported.

[0016] Preferably, a protective plate is provided at one end of the guide positioning rod, and a moving block is slidably connected to the surface of the guide positioning rod.

[0017] Preferably, the opposite surfaces of the two moving blocks are provided with the same sliding plate.

[0018] Furthermore, by setting up a protective plate, the moving block is prevented from sliding off the guide positioning rod, and by setting up the moving block, the connection and support of the sliding plate are maintained.

[0019] Preferably, a second return spring is sleeved on the surface of the guide positioning rod, one end of the second return spring is fixedly connected to the front of the moving block, and the other end of the second return spring is fixedly connected to the back of the positioning plate.

[0020] Furthermore, by setting a second reset spring, the moving block is driven to slide and reset, thereby causing the position of the sliding plate to change.

[0021] Preferably, the front of the sliding plate is provided with a plurality of fixing blocks, and two adjacent fixing blocks are adapted to the connecting strip, and the back of the sliding plate is provided with a connecting pull plate.

[0022] Furthermore, by setting a fixing block that cooperates with the connecting strip, the connecting strip is prevented from rotating, thereby fixing the connecting shaft in place.

[0023] In summary, the technical effects and advantages of this invention are as follows:

[0024] In this invention, by setting an installation ring, it is easy to apply torque to the cutting head and remove the cutting head. By setting an anti-slip pad, friction is increased to prevent slippage when in contact with its surface. By setting an angle instrument, the rotation angle is measured in degrees. By setting a positioning plate, it is fixed to an external object to maintain the stability of the device on the positioning plate. By setting a moving slide, space is provided for the lower cutting cylinder to move and avoid collisions with the external object to be processed when the cutting head cuts to a large depth, which would cause the lower cutting cylinder to bend and be scrapped.

[0025] In this invention, a telescopic rod is installed to prevent severe deformation of the first return spring. The first return spring drives the lower cutting cylinder to return to its stable position. A connecting shaft is installed to maintain stable support for the rotating disk.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example: Reference Figure 1-6 The present invention relates to a multifunctional CNC cutting machine holder, comprising an upper connecting cylinder 1, a lower cutting cylinder 2 disposed below the upper connecting cylinder 1, a cutting head 3 threadedly connected to the bottom end of the lower cutting cylinder 2, an installation ring 4 disposed on the surface of the cutting head 3, anti-slip pads 5 disposed on the surfaces of both the upper connecting cylinder 1 and the lower cutting cylinder 2, a positioning plate 7 disposed at the rear of the upper connecting cylinder 1, an angle gauge 6 disposed on the front of the positioning plate 7, and an angle adjustment mechanism 8 disposed at the bottom end of the upper connecting cylinder 1.

[0037] The above structure, with the upper connecting cylinder 1 and the lower cutting cylinder 2, maintains the overall connection of the equipment. The installation ring 4 facilitates the application of torque to the cutting head 3. When the cutting head 3 is removed, the anti-slip pad 5 increases friction and prevents slippage when in contact with its surface. The angle instrument 6 measures the rotation angle. The positioning plate 7 is fixed to an external object to maintain the stability of the device on the positioning plate 7. The angle adjustment mechanism 8 provides a reference and positioning for the rotation angle, while preventing the cutting head 3 from falling and hitting the external object to be processed, thus preventing damage.

[0038] As an excellent implementation method in this embodiment, the angle adjustment mechanism 8 includes a movable slide groove 818 formed at the bottom end of the upper connecting cylinder 1. A telescopic rod 801 is mounted on the inner top wall of the movable slide groove 818. The bottom end of the telescopic rod 801 is fixedly connected to the top end of the lower cutting cylinder 2. The surface of the lower cutting cylinder 2 is slidably connected to the inner wall of the movable slide groove 818. A first return spring 807 is sleeved on the surface of the telescopic rod 801. The top end of the first return spring 807 is fixedly connected to the inner top wall of the movable slide groove 818, and the bottom end of the first return spring 807 is fixedly connected to the top end of the lower cutting cylinder 2. By setting the movable slide groove 818, space is provided for the lower cutting cylinder 2 to move and avoid impacts, preventing the cutting head 3 from hitting the object to be processed at a large depth, thus causing the lower cutting cylinder 2 to bend and become unusable. By setting the telescopic rod 801, severe deformation of the first return spring 807 is prevented. By setting the first return spring 807, the lower cutting cylinder 2 is driven to return to its original position and remain stable.

[0039] As an excellent implementation method in this embodiment, a connecting shaft 809 is rotatably connected to the inner wall of the positioning plate 7. A rotating disk 803 is provided at one end of the connecting shaft 809. A through hole is opened on the surface of the rotating disk 803, and a positive and negative lead screw 804 is rotatably connected to the inner wall of the through hole. By setting the connecting shaft 809, stable support for the rotating disk 803 is maintained, and by setting the through hole, the installation of the positive and negative lead screw 804 is avoided.

[0040] In this embodiment, an operating knob 802 is provided at one end of the positive and negative lead screw 804. An arc-shaped clamping plate 805 is threaded onto the surface of the positive and negative lead screw 804. The inner walls of the two arc-shaped clamping plates 805 are adapted to the surface of the lower cutting cylinder 2. A positioning ring 806 is provided on the surface of the lower cutting cylinder 2. By rotating the operating knob 802, the operator moves the two arc-shaped clamping plates 805 closer together or further apart. The arc-shaped clamping plates 805 clamp and fix the surface of the lower cutting cylinder 2, and the positioning ring 806 positions the clamping position of the arc-shaped clamping plates 805.

[0041] In this embodiment, an observation pointer 808 is provided on the surface of the connecting shaft 809, and multiple connecting strips 816 are provided on the surface of the connecting shaft 809. Multiple guide positioning rods 812 are provided on the back of the positioning plate 7. By providing the observation pointer 808, the reference angle instrument 6 can easily know the angle of rotation. By providing the connecting strips 816, the rotation of the connecting shaft 809 drives the rotation of the connecting strips 816. By providing the guide positioning rods 812, the movement of the moving block 814 is guided and supported.

[0042] In this embodiment, a protective plate 817 is provided at one end of the guide positioning rod 812, and a moving block 814 is slidably connected to the surface of the guide positioning rod 812. The opposite surfaces of the two moving blocks 814 are provided with the same sliding plate 811. By providing the protective plate 817, the moving block 814 is prevented from sliding off the guide positioning rod 812. By providing the moving block 814, the connection and support of the sliding plate 811 are maintained.

[0043] In this embodiment, a second return spring 813 is sleeved on the surface of the guide positioning rod 812. One end of the second return spring 813 is fixedly connected to the front of the moving block 814, and the other end is fixedly connected to the back of the positioning plate 7. By setting the second return spring 813, the moving block 814 is driven to slide and reset, thereby causing the position of the sliding plate 811 to change.

[0044] In this embodiment, the front of the sliding plate 811 is provided with a plurality of fixing blocks 815, and two adjacent fixing blocks 815 are adapted to the connecting strip 816. The back of the sliding plate 811 is provided with a connecting pull plate 810. By setting the fixing blocks 815 to cooperate with the connecting strip 816, the connecting strip 816 is prevented from rotating, thereby positioning and fixing the connecting shaft 809.

[0045] The working principle of this invention is as follows: A multifunctional CNC cutting machine clamp. When using it, the user first installs and fixes the positioning plate 7 on the external equipment. In the initial state, the pointer 808 is observed to be in the middle position of the angle instrument 6. At this time, the positioning plate 7 is perpendicular to the external reference plane. The upper connecting cylinder 1 and the lower cutting cylinder 2 are brought close to the arc-shaped clamping plate 805. The operator then rotates the operating knob 802, which causes the two arc-shaped clamping plates 805 to move closer together, clamping and fixing the surface of the lower cutting cylinder 2. The positioning ring 806 assists in positioning the clamping position of the arc-shaped clamping plate 805. When it is necessary to rotate the cutting head 3 to cut at an angle, the connecting pull plate 810 is pulled back. The movement of the connecting pull plate 810 causes the sliding plate 811 and the moving block 814 to slide along the surface of the guide positioning rod 812. This causes the second return spring 813 to stretch and lengthen, causing the fixing block 815 to move away from the connecting strip 816 and release the locking state of the connecting strip 816. Adjust the rotation of the lower cutting cylinder 2 so that the rotating disk 803 rotates around the connecting shaft 809. The rotation of the connecting shaft 809 drives the observation pointer 808 to rotate. By observing the angle reading on the angle instrument 6 through the rotation of the observation pointer 808, the tilt cutting angle of the cutting head 3 can be understood. At this time, the connecting pull plate 810 can be released, so that the moving block 814 drives the sliding plate 811 to reset under the action of the second reset spring 813, so that the fixing block 815 is locked in the connecting strip 816 to prevent the connecting shaft 809 from continuing to rotate. When the cutting head 3 drops a large height due to operational errors, the space of the moving slide 818 can also be used for safety protection to prevent the cutting head 3 from hitting the external object to be processed when it drops too deep, causing the lower cutting cylinder 2 to bend and be scrapped. When the equipment is in use, the first reset spring 807 drives the lower cutting cylinder 2 to reset and maintain stability. With the above structure, the rotation angle is referenced and positioned, and the cutting head 3 is prevented from falling and hitting the external object to be processed, causing damage.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
