Description

Technical Field

[0001] This utility model relates to the field of air compressor housing processing, and in particular to a positioning device for air compressor housing processing. Background Technology

[0002] Chinese Patent No. CN217647967U discloses an auxiliary positioning device for processing air compressor housings, including a processing table and a support plate disposed above the processing table. A slot is formed on the upper surface of the processing table, and a slot seat is disposed in the slot. The support plate is disposed on the top surface of the slot seat. Positioning grooves are symmetrically arranged on the two side walls of the slot seat. Positioning pins are slidably disposed at both ends of the processing table and are inserted into the positioning grooves when the slot seat is installed in the slot. Clamping plates are respectively disposed at both ends of the top surface of the processing table, which can be close to each other to clamp the air compressor housing mounted on the support plate or far apart to release the air compressor housing.

[0003] Air compressor housings typically have mating grooves or installation spaces for mounting support plates. When the mating grooves and installation spaces at the bottom of the air compressor housing change, the positioning pins on both sides of the processing table can be disengaged from the positioning grooves to remove the mounting bracket and the support plate on top of the mounting bracket from the processing table. Subsequently, mounting brackets with support plates of other sizes can be installed on the processing table to replace the support plate. However, when replacing the support plate, since the support plate is located on top of the mounting bracket, the mounting bracket will also be replaced. Only the support plate needs to be replaced. Replacing the mounting bracket along with the support plate will result in material waste and increase the space required to store the support plate and mounting bracket. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies, which require replacing the support plate along with the card holder, leading to material waste, increased costs, and increased space requirements for stacking and storage. It provides a positioning device for processing air compressor housings with a detachable positioning plate.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A positioning device for processing an air compressor housing includes a worktable, a positioning plate disposed on the worktable for positioning and placing a workpiece, and a clamping component disposed on the worktable for fixing the workpiece placed on the positioning plate. A detachable component is provided between the positioning plate and the worktable to enable disassembly and assembly between the two. The detachable component includes an "L"-shaped limiting plate symmetrically disposed at the bottom of the positioning plate and two "L"-shaped limiting arc grooves disposed on the top surface of the worktable. One end of the limiting arc groove is provided with an opening for the limiting plate to be inserted into the limiting arc groove. A limiting component is provided between the worktable and the positioning plate to limit the position of the limiting plate when the limiting plate is located at the end of the limiting arc groove away from the opening. The limiting plate is telescopically disposed at the bottom of the positioning plate, and when the limiting plate is retracted into the positioning plate, its bottom surface is flush with the bottom surface of the positioning plate.

[0006] Using the above solution, the limiting plate located at the bottom of the positioning plate can be inserted into the limiting arc groove from the opening when the positioning plate is installed on the top surface of the worktable. When the limiting plate is inserted into the limiting arc groove and moves to the end of the limiting arc groove away from the opening, the position of the limiting plate can be limited by the limiting component, thereby realizing the installation between the positioning plate and the worktable. The disassembly of the positioning plate and the worktable is similar. The positioning plate and the worktable can be connected by the assembly between the limiting plate and the limiting arc groove and the limiting component limiting the movement of the limiting plate in the limiting arc groove, thereby reducing the cost required for the disassembly and assembly of the positioning plate. At the same time, by setting the limiting plate telescopically at the bottom of the positioning plate, the space required for the positioning plate to be stacked and stored can be reduced.

[0007] Preferably, the limiting plate includes a vertically arranged insert block and a limiting block with a horizontal protrusion on the side wall of the insert block, and the limiting arc groove includes a slot recessed on the top surface of the workbench and a limiting groove provided on the side wall of the slot near the bottom.

[0008] Preferably, the limiting component includes a limiting hole on the limiting block, a first insertion hole on the top surface of the workbench that communicates with the limiting groove, a second insertion hole on the positioning plate that is opposite to the first insertion hole, and a limiting pin that is simultaneously inserted into the first insertion hole, the second insertion hole, and the limiting hole.

[0009] Using the above solution, when the positioning plate is installed on the top surface of the workbench and the bottom of the positioning plate moves to the end of the limiting arc groove away from the opening of the limiting arc groove, the limiting pin can pass through the first through hole and the second insertion hole and engage with the limiting hole on the limiting block, thereby preventing the limiting block from moving in the limiting groove and limiting the position of the limiting plate, thus preventing the positioning plate from deflecting after it is installed on the top surface of the workbench.

[0010] Preferably, after the limiting pin is inserted into the limiting hole, its top surface is flush with the top surface of the positioning plate, and an operating component is provided on the top surface of the positioning plate to facilitate the operator to remove the limiting pin.

[0011] Preferably, the operating component includes an operating groove on the top surface of the positioning plate that communicates with the second insertion hole.

[0012] Using the above solution, the operating groove on the top surface of the positioning plate allows the operator to easily disengage the limiting pin from the limiting hole on the limiting block, thereby releasing the limitation on the movement of the limiting block and allowing the limiting block to move within the limiting arc groove, thus realizing the disassembly of the positioning plate from the worktable.

[0013] Preferably, the bottom of the positioning plate is symmetrically provided with two storage slots, and the two limiting plates are respectively telescopically installed in their corresponding storage slots. When the limiting plates are retracted into the storage slots, their bottom surfaces are flush with the bottom surfaces of the positioning plate. An anti-detachment component is provided between the storage slot for storing the plug and the side wall of the plug to prevent the plug from completely detaching from the storage slot.

[0014] Preferably, the anti-detachment component includes elastic hooks respectively provided on the four side walls of the insertion block and snap-fit ​​grooves respectively provided on the four side walls of the storage groove for storing the insertion block, for inserting the elastic hooks and for engaging with the ends of the elastic hooks. The four side walls of the insertion block are respectively provided with clearance grooves for the elastic hooks to deform, and the elastic hooks are vertically provided in the clearance grooves near the side walls of the insertion block.

[0015] Using the above solution, the elastic hook can move within the locking groove as the limiting plate moves within the storage groove. When the end of the elastic hook engages with the end of the locking groove, the limiting plate can be prevented from coming out of the storage groove. The limiting plate is telescopically set at the bottom of the positioning plate, so that when the positioning plates are stacked elsewhere, the limiting plate can retract into the positioning plate, thereby reducing the space required for stacking the positioning plates.

[0016] Preferably, the clamping component includes two clamping plates symmetrically arranged on the top surface of the worktable and a driving component for driving the two clamping plates closer to or further apart from each other.

[0017] Preferably, the driving component includes a drive motor mounted on the worktable, a bidirectional screw mounted on the output shaft of the drive motor, and sliders mounted on the two threaded sections of the bidirectional screw that move with the rotation of the bidirectional screw. The clamping plate is mounted on the sliders, and the worktable has a guide groove for guiding the sliders to slide within it.

[0018] With the above solution, the two clamping plates set on the worktable can move closer or further apart simultaneously under the drive of the drive motor, and the two clamping plates can be moved simultaneously by a bidirectional screw, which makes the overall control molding simpler and reduces the cost required to drive the clamping plates to move.

[0019] This utility model, by adopting the above technical solution, has significant technical effects: the limiting plate set at the bottom of the positioning plate can be inserted into the limiting arc groove from the opening of the limiting arc groove when the positioning plate is installed on the top surface of the worktable. When the limiting plate is inserted into the limiting arc groove and moves to the end of the limiting arc groove away from the opening, the position of the limiting plate can be limited by the limiting component, thereby realizing the installation between the positioning plate and the worktable. The disassembly of the positioning plate and the worktable is similar. The positioning plate and the worktable can be connected by the assembly between the limiting plate and the limiting arc groove and the limiting component limiting the movement of the limiting plate in the limiting arc groove, thereby reducing the cost required for the disassembly and assembly of the positioning plate. At the same time, by setting the limiting plate telescopically at the bottom of the positioning plate, the space required for the positioning plate to be stacked and stored can be reduced.
