Description

Technical Field

[0001] This utility model belongs to the technical field of impact test specimen processing equipment, specifically relating to an automated gripping device for an impact test specimen processing center. Background Technology

[0002] Testing the physical properties of metallic materials requires a large number of impact test specimens. To ensure the accuracy of the test results, the various properties of the impact test specimens themselves should be kept consistent.

[0003] Currently, fully automated impact test specimen machining centers can directly process blanks into standard impact test specimens through multiple machining processes on the same machine, including face milling, side milling, bottom milling, V-cut milling, marking, deburring milling, and cutting. For example, Chinese utility model patent document CN201436138U discloses a CNC machining center for impact test specimens. However, when cutting the impact test specimens, the lack of specimen fixation allows them to easily fly off with the high-speed rotating cutter after cutting, affecting the cutting quality, posing safety hazards, and making it inconvenient to collect the cut impact test specimens.

[0004] Therefore, it is necessary to design an automated gripping device for impact specimen processing centers that can clamp and fix impact specimens, ensure specimen cutting quality, and facilitate collection to solve the current technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automated gripping device for impact sample processing centers that can clamp and fix impact samples, ensure sample cutting quality, and facilitate collection.

[0006] The technical solution of this utility model is as follows: an automated gripping device for an impact sample processing center, including a pneumatic finger, one end of which has two fingers and a gripper on each finger; the other end of which is provided with a translation drive component for extending or resetting in the horizontal direction; the top of the translation drive component is provided with a lifting drive component for descending or resetting in the vertical direction; a three-position four-way solenoid valve is connected to the translation drive component for controlling the switching of the translation drive component between an extended state, a reset state, and a floating state.

[0007] Furthermore, the translation drive component is a three-axis cylinder, and the three-position four-way solenoid valve is a Y-type three-position four-way solenoid valve; the rodless chamber of the translation drive component is connected to port A of the three-position four-way solenoid valve, the rod chamber of the translation drive component is connected to port B of the three-position four-way solenoid valve, and port P of the three-position four-way solenoid valve is connected to the air source.

[0008] Furthermore, the gripper has a clamping plate, and a mounting block is fixedly provided at one end of the clamping plate. The mounting block is detachably and fixedly connected to the finger.

[0009] Furthermore, the top of the mounting block has a slot that matches the finger, the finger is installed inside the slot, and the mounting block and the finger are detachably fixedly connected by bolts.

[0010] Furthermore, the top of the clamping plate is provided with a limiting block that matches the top of the impact specimen, and the limiting blocks on the top of the two clamping plates are staggered.

[0011] Furthermore, the lifting drive component is a three-axis cylinder, and a mounting housing is fitted on the outer side of the lifting drive component. A mounting bracket is provided on one side of the lifting drive component, and the mounting bracket is assembled inside the mounting housing.

[0012] Furthermore, a protective cover is provided at the bottom of the mounting housing.

[0013] Furthermore, a marking machine bracket is fixedly installed on one side of the mounting housing, and a marking machine is installed inside the lower end of the marking machine bracket.

[0014] The beneficial effects of this utility model are: (1) In this utility model, before cutting, the lifting drive component drives the jaws to descend to the height corresponding to the impact sample, and then the translation drive component drives the jaws to extend to the position corresponding to the impact sample. At this time, the pneumatic fingers drive the jaws to clamp on both sides of the impact sample. Then the translation drive component switches to the floating state, and the milling head device can move and cut relative to the impact sample while keeping the jaws clamped on the impact sample to ensure the quality of sample cutting. (2) After the impact sample is cut, the translation drive component switches to the reset state and moves with the milling head device to a fixed position to collect the impact sample, which facilitates the collection of the impact sample.

[0018] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are not intended to limit the present invention or its application or use in any way. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete, and to fully express the scope of the present invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0019] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] like Figures 1 to 3 As shown, the automated gripping device for the impact sample processing center includes a pneumatic finger 3. One end of the pneumatic finger 3 has two fingers 31, each with a gripper 4. The other end of the pneumatic finger 3 is equipped with a translation drive component 2 that drives it to extend or retract horizontally. The top of the translation drive component 2 is equipped with a lifting drive component 1 that drives it to descend or retract vertically. A three-position four-way solenoid valve 5 is connected to the translation drive component 2 to control its switching between extended, retracted, and floating states. In this embodiment, the lifting drive component 1 of the automated gripping device for the impact sample processing center is fixedly installed outside the milling head housing, and the translation drive component 2 drives the gripper... The jaw 4 extends or resets in the same direction as the cutting movement. Before cutting, the lifting drive component 1 drives the jaw 4 to descend to the height corresponding to the impact sample. Then, the translation drive component 2 drives the jaw 4 to extend to the position corresponding to the impact sample. At this time, the pneumatic fingers 3 drive the jaw 4 to clamp the impact sample on both sides. Then, the translation drive component 2 switches to the floating state, and the X-axis slide system drives the impact sample to move. The milling head device can move and cut relative to the impact sample while keeping the jaw 4 clamping the impact sample to ensure the quality of sample cutting. After the impact sample is cut, the translation drive component 2 switches to the reset state and moves with the milling head device to a fixed position to collect the impact sample, which is convenient for collecting the impact sample.

[0021] In some embodiments, the translation drive component 2 is a three-axis cylinder. The piston rod of the three-axis cylinder is extended in its extended state, and retracted in its reset state. The piston rod of the three-axis cylinder is free to move under external force in a floating state. The three-position four-way solenoid valve 5 is a Y-type three-position four-way solenoid valve. The rodless chamber of the translation drive component 2 is connected to port A of the three-position four-way solenoid valve 5, the rod chamber of the translation drive component is connected to port B of the three-position four-way solenoid valve 5, and port P of the three-position four-way solenoid valve 5 is connected to the air source 6. Figure 2 As shown, when the left coil of the three-position four-way solenoid valve 5 is energized, the air source 6 supplies air to the rodless chamber of the three-axis cylinder, and the piston rod of the three-axis cylinder extends, which is its extended state; when the right coil of the three-position four-way solenoid valve 5 is energized, the air source 6 supplies air to the rod chamber of the three-axis cylinder, and the piston rod of the three-axis cylinder retracts, which is its reset state; when the three-position four-way solenoid valve 5 is in the neutral position, the piston rod of the three-axis cylinder can move freely under the action of external force, which is its floating state.

[0022] In some embodiments, the gripper 4 has a clamping plate 41, and a mounting block 43 is fixedly provided at one end of the clamping plate 41. The mounting block 43 is detachably and fixedly connected to the finger 31. The thickness of the clamping plate 41 in the vertical direction is less than that of the impact specimen. When the two clamping plates 41 clamp the two sides of the impact specimen, a space is reserved below the clamping plates 41 for the tool to cut the impact specimen.

[0023] In some embodiments, the top of the mounting block 43 is provided with a slot 44 that matches the finger 31. The finger 31 is installed inside the slot 44, which improves the stability of the connection between the finger 31 and the mounting block 43. The mounting block 43 and the finger 31 are detachably fixedly connected by bolts; the gripper 4 can be disassembled and replaced.

[0024] In some embodiments, the top of the clamping plate 41 is provided with a limiting block 42 that matches the top of the impact sample. The limiting blocks 42 on the top of the two clamping plates 41 are staggered. The limiting blocks 42 increase the contact area between the gripper 4 and the impact sample, ensuring the stability of the clamping.

[0025] In some embodiments, the lifting drive component 1 is a three-axis cylinder, and a mounting housing 7 is fitted on the outer side of the lifting drive component 1. A mounting bracket 11 is provided on one side of the lifting drive component 1, and the mounting bracket 11 is assembled inside the mounting housing 7.

[0026] In some embodiments, a protective cover 8 is provided at the bottom of the mounting housing 7. In the idle state, the translation drive component 2, the pneumatic finger 3 and the gripper 4, which are in the reset state, are located inside the protective cover 8. Before the impact sample needs to be gripped, the lifting drive component 1 drives the translation drive component 2 to move downward from inside the protective cover 8.

[0027] In some embodiments, a marking machine bracket 91 is fixedly provided on one side of the mounting housing 7, and a marking machine 9 is provided inside the lower end of the marking machine bracket 91; the marking machine 9 is used to mark one side of the impact sample before the impact sample is cut.
