Description

Technical Field

[0001] This utility model relates to the field of auxiliary accessories for machining equipment, specifically to a feeding device. Background Technology

[0002] In existing CNC lathes (horizontal), loading and unloading are generally done manually or by using multi-axis robotic arms. However, the installation cost of multi-axis robotic arms is high. Therefore, many modification manufacturers often install loading robotic claws on the lathe's pallet, which can easily affect tool installation and interfere with toolpaths. Furthermore, the increased loading cycle time exacerbates the wear of the lathe guideways. The space occupied by the increased number of attachments on the pallet directly affects the effective machining stroke of the lathe tool post. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a feeding device that can be adapted to CNC lathes and can effectively avoid obstructing the operating space.

[0004] To address the above problems, the following technical solution is provided: A feeding device, comprising a first sliding device and a second sliding device, and a connecting base. The connecting base has an upwardly inclined fixed base surface at its rear end in the longitudinal direction, and a rightwardly extending transverse support is mounted on the fixed base surface. The first sliding device includes a transverse slide rail fixed to the transverse support and a transverse slider adapted to slide therewith. The transverse slider has a connecting plate, a transverse motor located on the side of the transverse support facing the connecting base, and a lead screw connected to it. The connecting plate is fixed with a lead screw nut adapted to the thread of the lead screw. The second sliding device includes a longitudinal slider fixedly connected to the connecting plate and a longitudinal slide rail slidably engaged therewith. The longitudinal slide rail has a longitudinal support and a longitudinal pusher fixedly connected thereto. The push rod of the longitudinal pusher is connected to the connecting plate through a connecting frame. The longitudinal support has a clamp mounting position. The surface of the connecting plate is parallel to the fixed base surface, and the sliding direction of the longitudinal slide rail and the sliding direction of the transverse slider intersect at a 90-degree angle when projected onto the fixed base surface.

[0005] In the above structure, the connecting base is fixed above the lathe headstock, and its fixed base surface is located at the rear side of the lathe headstock, allowing the transverse support located above and behind the lathe headstock to extend towards the lathe tailstock. The transverse slide rail, transverse slider, transverse motor, lead screw, and lead screw nut enable the transverse movement of the connecting plate. Then, the longitudinal slider, longitudinal slide rail, longitudinal pusher, and connecting frame enable the sliding of the longitudinal support. The sliding direction of the longitudinal support is the same as the tilt direction of the fixed base surface, allowing it to intrude into the lathe axis position during loading and tilt backward and upward after loading to provide sufficient machining space for the lathe. Simultaneously, the longitudinal slider is fixed to the connecting plate, and using the longitudinal slide rail as the sliding object avoids the longitudinal slide rail occupying machining space while maintaining a constant sliding stroke.

[0006] The present invention is further configured such that the transverse slide rails are two parallel and spaced apart from each other; each transverse slide rail is provided with two transverse sliders.

[0007] The above structure can effectively improve the stability of the connecting plate.

[0008] The present invention is further configured such that the lead screw is located between two transverse slide rails; the transverse support is provided with a first clearance groove in the direction of movement of the lead screw nut.

[0009] In the above structure, the opening of the first clearance groove allows the axis of the lead screw nut to be closer to the surface of the transverse support, which can reduce the height on the one hand and improve the overall rigidity on the other.

[0010] The present invention is further configured such that the connecting plate is provided with a nut mounting groove, the lead screw nut is mounted on a nut bracket, the nut bracket passes through the nut mounting groove from the front of the connecting plate so that the lead screw nut reaches the back of the connecting plate, and the nut bracket is connected to the front of the connecting plate by screws.

[0011] In the above structure, the nut bracket is T-shaped and passes through the nut mounting slot, which allows the axis of the lead screw nut to be closer to the back of the connecting plate. This reduces the height and improves the overall rigidity.

[0012] The present invention is further configured such that a buffer bracket is provided at the end of the transverse support away from the connecting base, and a buffer block is provided on the buffer bracket; when the connecting plate moves to the right to the limit position, it abuts against the buffer block.

[0013] The above structure is used to provide buffer protection during overtravel.

[0014] The present invention is further configured such that the longitudinal slide rail is matched with two longitudinal sliders.

[0015] The above structure improves the stability between the longitudinal slider and the longitudinal slide rail.

[0016] The present invention is further configured such that the push rod of the longitudinal pusher is inclined upward in the outward direction.

[0017] In the above structure, when the push rod of the longitudinal pusher extends outward, the longitudinal pusher tilts downward to lower the center of gravity and improve stability.

[0018] The present invention is further provided that the connecting base is provided with mounting holes.

[0019] In the above structure, the mounting hole is used to connect to the lathe headstock.

[0020] The present invention is further configured such that the longitudinal pusher is a cylinder.

[0021] The above structure has the advantages of being lightweight, having a sensitive response, and having overload protection.

[0022] The present invention is further configured such that a clamp is installed at the clamp mounting position.

[0023] In the above structure, the clamp is a mechanical claw or a suction cup.

[0024] The beneficial effects of this utility model are as follows: The connecting base is fixed above the headstock of the lathe, and its fixed base surface is located at the rear side of the headstock, allowing the transverse support located above the rear of the lathe headstock to extend towards the tailstock. The transverse slide rail, transverse slider, transverse motor, lead screw, and lead screw nut enable the transverse movement of the connecting plate. Then, the longitudinal slider, longitudinal slide rail, longitudinal pusher, and connecting frame enable the sliding of the longitudinal support. The sliding direction of the longitudinal support is the same as the tilt direction of the fixed base surface, thus allowing it to intrude into the lathe axis position during loading and tilt backward and upward after loading, providing ample machining space for the lathe. Simultaneously, the longitudinal slider is fixed to the connecting plate, and using the longitudinal slide rail as the sliding object avoids the longitudinal slide rail occupying machining space while maintaining a constant sliding stroke.

[0037] In the above structure, the nut bracket 32 ​​is T-shaped and passes through the nut mounting groove 231, which can make the axis of the lead screw nut 26 closer to the back of the connecting plate 23. On the one hand, it can reduce the height, and on the other hand, it can improve the overall rigidity.
