Description

Technical Field

[0001] This utility model relates to the field of non-standard automated auxiliary equipment, and in particular to a movable magnetic height-sensing mechanism. Background Technology

[0002] In the field of non-standard automated equipment, detecting the height of the workpiece surface (i.e., "height detection") is a common and critical function. Before processing or inspection, the position of the workpiece surface must be determined quickly and accurately so that the equipment can locate the focal point or tool starting point and ensure the consistency of processing quality.

[0003] Current height-probing structures are all fixed installations, which are complex and inconvenient to move and adjust. Therefore, there is an urgent need to develop a height-probing mechanism that is easy to install and can be moved quickly. Utility Model Content

[0004] The purpose of this invention is to provide a movable magnetic height detection mechanism that simplifies the installation structure, facilitates position adjustment, and can be quickly deployed in different positions of non-standard automated equipment to achieve workpiece height detection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a movable magnetic height detection mechanism, including a base, at least two linear bearings are provided on the base, each linear bearing is equipped with a linear guide post, the ends of all linear guide posts away from the base are connected to a height detection plate, and a compression spring is provided between the height detection plate and the base. The base includes two mounting blocks for installation, the mounting blocks and the main body of the base form a concave shape, the mounting base has an installation opening, a magnet is installed in the installation opening, and the base is installed on the equipment by the magnetism of the magnet.

[0006] Preferably, the magnet is completely inside the mounting opening, and the magnet's adsorption surface is 0.5-2mm lower than the surface of the mounting block, with two magnets mounted on each mounting block.

[0007] Preferably, a photoelectric sensor is provided on the side of the base away from the linear bearing, the linear guide post passes through the base, and a sensing mounting block is installed on the part of one of the linear guide posts that passes through the base, the sensing mounting block cooperating with the photoelectric sensor.

[0008] Preferably, the photoelectric sensor is a U-shaped slot photoelectric switch, which is mounted on the main body of the base by a bracket, and the U-shaped slot corresponds to the horizontal section of the sensing mounting block. When the sensing mounting block moves up and down with the linear guide post, it can block or disconnect the light path of the photoelectric sensor, thereby generating an electrical signal.

[0009] Preferably, the sensing mounting block is mounted on the linear guide post by sensing mounting bolts, and a contact sensor is embedded in the sensing mounting block at a position that is close to and extends beyond the linear guide post. The contact sensor contacts the base to generate a contact sensing signal. When no external force is applied, the sensing mounting block adheres to the base and generates a contact sensing signal under the action of the compression spring.

[0010] The technical effects of this utility model are as follows: It simplifies the installation structure and facilitates position adjustment, enabling rapid deployment in different locations on non-standard automated equipment to achieve workpiece height detection.

[0011] The design of the magnet being 0.5-2mm below the surface of the mounting block ensures good magnetic attraction for installation without affecting the movement and installation of the mounting block.

[0012] The design of the contact sensor can determine whether the compression spring is damaged in the initial stage by the sensing signal it generates. When the compression spring is damaged, its elasticity is insufficient to support the weight of the height probe, and no contact sensing signal will be generated. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0018] like Figure 1 and Figure 2As shown, this utility model is a movable magnetic height detection mechanism, including a base 11. At least two linear bearings 13 are mounted on the base 11, and each linear bearing 13 is equipped with a linear guide post 15. All the ends of the linear guide posts 15 away from the base 11 are connected to a height detection plate 18, and a compression spring 14 is provided between the height detection plate 18 and the base 11. The base 11 includes two mounting blocks for installation. The mounting blocks form a concave shape with the main body of the base 11. The mounting blocks have mounting openings, and magnets 12 are installed inside the mounting openings. The base 11 is installed onto the equipment by the magnets. The magnets 12 are completely inside the mounting openings, and the adsorption surface of the magnets 12 is 0.5-2mm lower than the surface of the mounting blocks. Each mounting block is equipped with... The base 11 is equipped with two magnets 12. A photoelectric sensor 17 is provided on the side of the main body away from the linear bearing 13. A linear guide post 15 passes through the main body of the base 11, and a sensing mounting block 16 is installed on the part of one of the linear guide posts 15 that passes through the base 11. The sensing mounting block 16 cooperates with the photoelectric sensor 17. The sensing mounting block 16 is L-shaped, and the horizontal section of the sensing mounting block 16 extends into the detection area of ​​the photoelectric sensor 17. The photoelectric sensor 17 is a U-shaped slot photoelectric switch, which is mounted on the main body of the base 11 by a bracket, and the U-shaped slot corresponds to the horizontal section of the sensing mounting block 16. When the sensing mounting block 16 moves up and down with the linear guide post 15, it can block or separate from the light path of the photoelectric sensor 17, thereby generating an electrical signal.

[0019] The specific uses of this utility model are as follows: Mechanism installation and position adjustment (this mechanism can probe height with the probe plate pointing downwards or upwards). The following shows the downward probe method. Specifically, the probe mechanism is placed on the metal workbench of an external non-standard automated equipment. The magnet 12 installed on the mounting block of the base 11 is used to achieve initial adsorption and fixation. According to the probe height position requirements of the workpiece to be inspected, the base 11 is pushed so that the probe plate 18 is moved directly above the workpiece to be inspected. After confirming the position, it is released, and the magnet 12 can stably adsorb the mechanism to complete the positioning.

[0020] Height detection process: When the external equipment moves the workpiece toward the height detection plate 18 (or the height detection mechanism moves with the equipment to above the workpiece and moves downward toward the workpiece), the surface of the workpiece contacts the bottom detection surface of the height detection plate 18. As the workpiece continues to move upward (or the mechanism continues to move downward), the workpiece generates an upward thrust on the height detection plate 18, pushing the height detection plate 18 to drive the linear guide post 15 to slide upward along the linear bearing 13. At this time, the compression spring 14 sleeved on the outside of the linear guide post 15 is compressed by the base 11 and the height detection plate 18 and contracts. At the same time, the sensing mounting block 16 on the linear guide post 15 moves upward and gradually disengages from the U-shaped slot of the photoelectric sensor 17. The optical path of the photoelectric sensor 17 is restored to conduction, generating an "in position" electrical signal and transmitting it to the external equipment control system.

[0021] Reset and Cyclic Detection: After a height detection is completed, the external equipment drives the workpiece to reset downwards (or the height detection mechanism resets upwards). The pushing force of the workpiece on the height detection plate 18 disappears, and the compression spring 14 returns to its natural state under the action of elastic force, pushing the height detection plate 18 and the linear guide post 15 downwards to the initial position. The sensing mounting block 16 re-enters the U-shaped slot of the photoelectric sensor 17 and blocks the light path. The photoelectric sensor 17 generates a "reset" electrical signal, and the mechanism returns to the detection state, ready for the next height detection operation.

[0022] like Figure 3 As shown, the sensing mounting block 16 is mounted on the linear guide post 15 by sensing mounting bolt 19, and a contact sensor 20 is embedded in the sensing mounting block 16 at a position that is close to and extends beyond the linear guide post 15. The contact sensor 20 contacts the base 11 to generate a contact sensing signal. When no external force is applied, the sensing mounting block 16 adheres to the base 11 and generates a contact sensing signal under the action of the compression spring 14.

[0023] In the initial state, the mechanism is placed in a square position, with the height probe 18 at the top. Without external force, the force generated by the compression spring 14 will support the height probe 18, causing the sensing mounting block 16 to adhere to the base 11 and the contact sensor 20 to generate a sensing signal. If the contact sensor 20 fails to generate a sensing signal in the initial state, it indicates that the compression spring 14 is damaged and needs to be replaced.
