Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to an automatic loading and unloading gripper mechanism for CNC machining. Background Technology

[0002] CNC machining centers, also known as numerical control milling machines, are a new type of machining mode based on computer programming technology to control machining programs, and have the advantage of high machining accuracy.

[0003] When machining small parts, existing CNC machining centers require CNC operators to manually load and unload the parts. Since the machining process requires the use of pure industrial oils, operators frequently come into contact with the oils when manually loading and unloading, which can affect their health. Furthermore, due to the small size of the parts, they are prone to falling or colliding when being picked up or placed, which can lead to damage. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic loading and unloading gripper mechanism for CNC machining, in order to solve the problem mentioned in the background art that when machining small parts, the existing CNC machining center requires CNC operators to manually load and unload the parts. Since pure industrial oil is used in the machining process, the operators will frequently come into contact with the oil when manually loading and unloading the parts, which will affect the health of the employees. In addition, since the parts are small in size, they are prone to falling or colliding when picking up and placing them, which will cause damage to the parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic loading and unloading gripper mechanism for CNC machining, including a contour gripper, a gripper cylinder is provided above the contour gripper, the contour gripper and the output end of the gripper cylinder are slidably connected, an air inlet connector is fixedly connected to the input end of the gripper cylinder, a fixed connecting block is fixedly installed on the upper surface of the gripper cylinder, a buffer mechanism is provided on the upper surface of the fixed connecting block, and a T-shaped block for connecting the machine tool is fixedly installed on the upper surface of the buffer mechanism.

[0006] The T-block is used for fixed connection with the CNC machine tool, so that the gripper mechanism is fixedly installed on the CNC machine tool. The buffer mechanism enables the gripper mechanism to flexibly grasp the parts and avoid damage to the parts. The external air source is connected through the air inlet connector, and then the gripper cylinder is controlled to make the contour gripper move in parallel to realize the clamping and releasing action, thereby grasping or putting down the parts.

[0007] Preferably, the shape of the contour gripper is designed according to the product's outline. This allows the contour gripper to hold the part more stably.

[0008] Preferably, the buffer mechanism includes equal-height bolts, springs, and equal-height bolt fixing blocks. Each of the four corners of the upper surface of the equal-height bolt fixing block has through holes matching the equal-height bolts. Four equal-height bolts are provided, each passing through a corresponding through hole. Four springs are provided, each sleeved on the outside of a corresponding equal-height bolt. Through the cooperation of the equal-height bolts, springs, and equal-height bolt fixing blocks, the gripper mechanism can simulate the manual handling and placement of materials by a worker, preventing damage to parts from gripping.

[0009] Preferably, the fixing block has matching threaded holes at the positions of the equalizing bolts, and the equalizing bolts and the fixing block are threaded together. This threaded connection allows the equalizing bolt fixing block to slide along the equalizing bolts above the fixing block.

[0010] Preferably, the fixed connecting block has a first limiting through hole in the middle, the equal height bolt fixing block has a second limiting through hole in the middle corresponding to the first limiting through hole, and the bottom of the T-block has a limiting groove corresponding to the second limiting through hole.

[0011] Preferably, a limiting rod is fixedly installed inside the first limiting through hole. The end of the limiting rod away from the first limiting through hole passes upward through the second limiting through hole and extends into the limiting groove. The limiting rod is slidably connected to the equal-height bolt fixing block and the T-block, respectively. When the buffer mechanism is running, the mutual cooperation of the limiting rod, the first limiting through hole, the second limiting through hole, and the limiting groove ensures that the fixed connecting block, the equal-height bolt fixing block, and the T-block are always on the same axis, preventing displacement.

[0012] Preferably, a waist hole is provided on the upper surface of the T-shaped block near both ends.

[0013] Preferably, a fixing screw is movably inserted into the waist hole. The clamping mechanism can be fixedly mounted on the machine tool through the cooperation of the fixing screw and the waist hole.

[0014] Preferably, a connector fixing block is fixedly installed on the lower side of the T-block, and an air blowing connector is fixedly installed on the connector fixing block. The air blowing connector connects to an external air source to clean the machine.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] This invention enables small-batch automated processing by using a gripper mechanism in conjunction with a CNC machine tool, replacing manual material handling, reducing labor costs, avoiding health risks to workers due to prolonged exposure to oil, and preventing damage from parts falling or colliding.
