Description

Technical Field

[0001] This utility model relates to the field of abrasive wheel mesh processing, and in particular to a picking mechanism for abrasive wheel mesh. Background Technology

[0002] Grinding wheel mesh is used to enhance the tensile strength of grinding wheels. It is formed by stamping a stack of whole sheets of mesh on a mesh forming press. The stamped rows of mesh need to be picked up and collected to facilitate subsequent processes. Traditionally, grinding wheel mesh is picked up manually, and can only be collected one stack at a time, not one row at a time, which is labor-intensive and inefficient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a grinding wheel mesh picking mechanism that facilitates the picking of grinding wheel mesh and improves picking efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a picking mechanism for abrasive wheel mesh, the innovation of which is: including A pickup base is provided, on which three pickup seats are installed in a triangular arrangement. Each pickup seat is also equipped with a pickup gripper. The three pickup seats are driven by a linear driver to move closer or further apart from each other, thereby causing the three pickup grippers to move closer or further apart from each other, thus enabling the gripping of the abrasive wheel mesh. A positioning component is provided on a pickup base. The positioning component includes a positioning rod that is vertically mounted on the pickup base. One side of the positioning rod extends out of the pickup base, and a positioning groove is provided on the positioning rod to cooperate with three pickup claws.

[0005] Furthermore, the picking gripper includes a gripping column and a gripper head disposed on the side of the gripping column away from the picking base. The gripping column has two sides distributed in a V-shape near the central axis of the picking base. The gripper head is composed of a guide section and a limiting section, and the size of the limiting section is larger than the size of the guide section and the size of the gripping column. The end face of the guide section away from the limiting section is a horizontal plane, and the size of the guide section gradually decreases from the connection side of the guide section and the limiting section. The positioning rod has a positioning section on the side extending out of the pickup seat. The positioning section has positioning grooves that cooperate with the three pickup claws. Each positioning groove fits into the two V-shaped sides of the clamping column, so that the cross-section of the positioning section is trident-shaped.

[0006] Furthermore, the pickup base, clamping post, and clamping head are all provided with an arc-shaped groove near the central axis of the pickup base.

[0007] Furthermore, the outer wall of the guide section of the clamp is an arc-shaped surface, and the three clamps are joined together to form a frustum structure.

[0008] Furthermore, the positioning rod is fixed to the pickup base by a spline connection.

[0009] The advantages of this utility model are as follows: The picking mechanism in this utility model, through the cooperation of the picking base, the picking seat, and the picking claw, can pick up the grinding wheel screen by moving the picking claw closer or further away, so as to pass through the through hole in the center of the grinding wheel screen. It is very convenient and no longer requires manual picking.

[0010] The arc-shaped groove design is intended to create a certain gap between the pickup base, clamp, chuck, and positioning section of the positioning rod when the three pickup bases approach each other. This allows the pickup base, clamp, and chuck to smoothly fit into the positioning groove of the positioning section, preventing the edges of the pickup base, clamp, and chuck from not fitting properly with the edges of the positioning groove, which would affect the positioning of the three chucks by the positioning section. At the same time, the existence of this gap also prevents the pickup base, clamp, and chuck from fitting too tightly into the positioning section of the positioning rod, which could cause jamming when the pickup base, clamp, and chuck separate from the positioning rod, thus making separation difficult.

[0011] The design of the frustum structure formed by the three grippers allows the picking jaws to pass more smoothly through the through hole in the center of the grinding wheel mesh. At the same time, the inclined surface of the frustum structure can guide and correct the relative position between the picking jaws 3 and the grinding wheel mesh, providing a good foundation for the subsequent gripping of the grinding wheel mesh by the picking jaws 3.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] like Figures 1-5 The illustrated picking mechanism for abrasive wheel mesh includes: A pickup base 1 is provided, on which three pickup seats 2 are mounted in a triangular arrangement. Each pickup seat 2 is also equipped with a pickup gripper 3. The three pickup seats 2 are driven by a linear actuator to move closer or further apart, thereby causing the three pickup grippers 3 to move closer or further apart, thus gripping the abrasive wheel mesh. The linear actuator is a cylinder. In this invention, the coordination between the pickup base 1 and the pickup seats 2 is the same as the structure and operating principle of the existing pneumatic three-jaw chuck, and will not be described in detail in this embodiment.

[0019] A positioning component is provided on the pickup base 1. The positioning component includes a positioning rod 4 vertically provided on the pickup base 1. The positioning rod 4 is fixed to the pickup base 1 by spline engagement. A through hole is opened at the center of the pickup base 1 to allow the positioning rod 4 to pass through and be installed vertically. One side of the positioning rod 4 extends out of the pickup base 2. A positioning groove 411 is opened on the positioning rod 4 to engage with three pickup claws 3.

[0020] Specifically, such as Figure 2 As shown in the schematic diagram, the pickup gripper 3 includes a gripper post 31 and a gripper head 32 disposed on the side of the gripper post 31 away from the pickup base. The gripper post 31 has two sides distributed in a V-shape near the central axis of the pickup base 1. The gripper head 32 is composed of a guide section 322 and a limiting section 321. The size of the limiting section 321 is larger than the size of the guide section 322 and the size of the gripper post 31. The end face of the guide section 322 away from the limiting section 321 is a horizontal plane. The size of the guide section 322 gradually decreases from the connection side of the guide section 322 and the limiting section 321.

[0021] The outer wall of the guide section 322 of the chuck 32 is an arc-shaped surface, and the cooperation of the three chucks 2 allows the three guide sections 322 to be spliced ​​together into a frustum structure when they are closed. Through this frustum structure design, the picking jaws 3 can pass through the through hole in the center of the grinding wheel mesh more smoothly. At the same time, the inclined surface of the frustum structure can be used to guide and correct the relative position between the picking jaws 3 and the grinding wheel mesh, providing a good foundation for the subsequent gripping of the grinding wheel mesh by the picking jaws 3.

[0022] When the three chucks 32 close together under the action of the pickup seat 2, the overall size of the three limiting sections 321 after the three chucks 32 close together is smaller than the size of the through hole in the center of the grinding wheel screen. This allows the three chucks 32 to pass smoothly through the through hole in the center of the grinding wheel screen. When the three chucks 32 separate together under the action of the pickup seat 2, the overall size of the three limiting sections 321 after the three chucks 32 separate is larger than the size of the through hole in the center of the grinding wheel screen, and the overall size of the three clamping posts 31 is smaller than the size of the through hole in the center of the grinding wheel screen. This allows for good pickup of the grinding wheel screen without causing cracking or tearing of the through hole in the center of the grinding wheel screen, thus avoiding damage to the grinding wheel screen during the pickup process.

[0023] like Figure 4 , Figure 5 As shown in the schematic diagram, the positioning rod 4 has a positioning section 41 on the side extending out of the pickup seat. The positioning section 41 has positioning grooves 411 that cooperate with the three pickup claws 3. Each positioning groove 411 fits into the two sides of the clamping column that are connected in a V-shape, so that the cross section of the positioning section 41 is similar to the three-pointed star shape of the Mercedes-Benz logo.

[0024] An arc-shaped groove 5 is also formed near the central axis of the pickup base 1 on the pickup seat 2, the clamping column 31, and the chuck 32. The arc-shaped groove 5 is designed to leave a certain gap between the pickup seat 2, the clamping column 31, the chuck 32 and the positioning section 41 of the positioning rod 4 when the three pickup seats 2 are close to each other. This allows the pickup seat 2, the clamping column 31, and the chuck 32 to fit smoothly into the positioning groove 411 of the positioning section 41. This avoids the corners of the pickup seat 2, the clamping column 31, and the chuck 32 not fitting into the corners of the positioning groove 411, which would affect the positioning of the three chucks 32 by the positioning section 41. At the same time, the existence of this gap also prevents the pickup seat 2, the clamping column 31, and the chuck 32 from fitting too tightly into the positioning section 41 of the positioning rod 4, which would cause jamming when the pickup seat 2, the clamping column 31, and the chuck 32 separate from the positioning rod 4, thus making separation difficult.

[0025] Working principle: When picking up the abrasive wheel screen, firstly, the picking mechanism is installed on the corresponding three-axis actuator. The three-axis actuator drives the entire picking mechanism to move above the abrasive wheel screen to be picked up. Then, the three-axis actuator drives the entire picking mechanism to descend. At this time, the three chucks 32 of the picking mechanism are in a closed state. As the picking mechanism descends, the three chucks 32 will pass through the through hole in the center of the abrasive wheel screen. After the chucks 32 pass through the through hole, the picking mechanism stops descending. Then, the linear actuator drives the three picking seats 2 to move away from each other, so that the overall size of the three limiting sections 321 is larger than the size of the through hole in the center of the abrasive wheel screen. Then, the three-axis actuator drives the entire picking mechanism to ascend, thereby driving the abrasive wheel screen to ascend and realizing the picking up of the abrasive wheel screen.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
