Description

Technical Field

[0001] This utility model relates to the field of sawing equipment technology, and more specifically, to a differential feed aluminum casting sawing equipment. Background Technology

[0002] Aluminum casting sawing equipment is a precision machine specifically designed for cutting and processing aluminum alloy castings. It uses a high-speed rotating saw blade to precisely cut the castings, removing risers, burrs, and flash, or dividing them into finished products of the required size. This equipment is widely used in the production of aluminum castings in the automotive, aerospace, photovoltaic, and construction industries, and is a key piece of equipment for improving processing efficiency and ensuring product quality.

[0003] Currently, after aluminum castings are poured, excess material such as risers and gates remains at the connection point of the mold pouring gate. To remove this excess material, aluminum casting sawing equipment is required. The commonly used aluminum casting sawing equipment is a multi-axis saw, with a multi-axis linear moving mechanism inside to adjust the sawing angle of the aluminum casting. Before sawing, a robotic arm needs to grab the aluminum casting and place it on the fixed platform of the multi-axis linear moving mechanism inside the multi-axis saw. However, to ensure processing safety, the multi-axis saw is generally a closed structure with only one door for the aluminum casting to enter and exit. This means that when sawing irregularly shaped aluminum castings, the robotic arm can easily interfere with the main structure of the multi-axis saw when grabbing the irregularly shaped aluminum casting and placing it on the fixed platform, thus affecting the sawing efficiency of the aluminum casting. In view of this, we propose a differential feed aluminum casting sawing equipment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a differential feed aluminum casting sawing device to solve the technical problem that the existing robotic arm is prone to interference with the main structure of the multi-axis saw when it grabs irregular aluminum castings and puts them into a fixed platform.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a differential feed aluminum casting sawing equipment, including a multi-axis saw; The multi-axis saw includes a saw base, and a mounting groove is provided on one side of the upper end face of the saw base. A mounting plate is symmetrically fixed inside the mounting groove, and a feeding assembly is detachably installed on the mounting plate. The feeding assembly includes a linear moving mechanism, which includes symmetrically arranged side plates and symmetrically fixed connecting frames between the side plates. A linear reciprocating mechanism is arranged between the connecting frames. A ball bearing seat is movably engaged on the linear reciprocating mechanism. A fixing component is fixedly connected to the bottom end of the ball bearing seat. The fixing component is detachably installed on the mounting plate. A sprocket is symmetrically and rotatably mounted on one side of the connecting frame. A transmission chain is connected between the sprockets on the same side. The transmission chain is detachably connected to the fixing component. A feeding component is slidably mounted on the top of the connecting frame. The bottom of the feeding component is detachably connected to the transmission chain.

[0006] Preferably, the linear reciprocating mechanism includes a motor detachably mounted on one side of the side plate, the motor being connected via a motor shaft to a lead screw rotatably mounted between the side plates, and the ball bearing seat being movably engaged with the lead screw.

[0007] Preferably, the fixing component includes a fixing plate that is detachably mounted on the mounting plate, and a connecting seat is symmetrically and detachably mounted on both sides of the upper end surface of the fixing plate, and the top of the connecting seat is detachably connected to the transmission chain.

[0008] Preferably, the bottom sides of the feeding component are symmetrically and detachably equipped with connecting seats II, the bottom ends of the connecting seats II are detachably connected to the transmission chain, and the bottom sides of the feeding component are also symmetrically and detachably equipped with positioning sliders II.

[0009] Preferably, positioning sliders are symmetrically arranged on both sides of the upper end face of the fixing plate, and the positioning sliders are detachably installed on the fixing plate.

[0010] Preferably, both the upper and lower surfaces of the connecting frame are detachably equipped with positioning slide rails, the second positioning slider is slidably mounted on the positioning slide rail located at the top of the connecting frame, and the first positioning slider is slidably mounted on the positioning slide rail located at the bottom of the connecting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a linear reciprocating mechanism, a ball bearing seat, a fixed plate, a connecting seat, a sprocket, a transmission chain, and a feeding assembly. The linear reciprocating mechanism drives the ball bearing seat to move. Since the ball bearing seat is fixed on the fixed plate, and the fixed plate is fixed on the mounting plate, the linear reciprocating mechanism itself moves under the interaction of forces. Because the connecting seat is detachably connected to the transmission chain, it pulls the transmission chain during the movement of the linear reciprocating mechanism. Furthermore, the feeding assembly is detachably connected to the transmission chain, so the transmission chain also drives the feeding assembly itself to move. Therefore, the movable design of the linear reciprocating mechanism facilitates its extension from inside the multi-axis saw, making it convenient for the robotic arm to grasp and place aluminum castings. This helps reduce interference between the aluminum castings and the multi-axis saw during the loading process, solving the problem of interference between the existing robotic arm and the main structure of the multi-axis saw when grasping irregularly shaped aluminum castings and placing them on the fixed platform.

[0012] 2. This utility model also designs different mechanical drive methods for the linear reciprocating mechanism and the feed assembly. The linear reciprocating mechanism is driven by the meshing of the lead screw and the ball bearing seat, while the feed assembly is driven by the pull of the transmission chain. That is, the two drive methods have different feed speeds, realizing differential feed in the same direction. This is beneficial for the feed assembly to obtain a longer travel stroke, and it is also beneficial for keeping the feed assembly further away from the multi-axis sawing machine, further reducing the interference between the aluminum casting and the multi-axis sawing machine during the loading process. In addition, the two drive methods use the same set of motors as the drive source to achieve synchronous operation, which helps to reduce the feeding steps in the processing process and reduce maintenance costs.

[0015] like Figures 1-6 As shown, this utility model relates to a differential feed aluminum casting sawing equipment, including a multi-axis saw 1; The multi-axis saw 1 includes a saw base 101. A mounting groove 102 is provided on one side of the upper end face of the saw base 101. A mounting plate 103 is symmetrically fixed inside the mounting groove 102. A feeding assembly 2 is detachably installed on the mounting plate 103. The feeding assembly 2 includes a linear moving mechanism 3. The linear moving mechanism 3 includes symmetrically arranged side plates 301 and symmetrically fixed connecting frames 302 between the side plates 301. A linear reciprocating mechanism is arranged between the connecting frames 302. A ball seat 7 is movably engaged on the linear reciprocating mechanism. A fixing component is fixedly connected to the bottom end of the ball seat 7. The fixing component is detachably installed on the mounting plate 103. A sprocket 306 is symmetrically and rotatably mounted on one side of the connecting frame 302. A transmission chain 307 is connected between the sprockets 306 on the same side. The transmission chain 307 is detachably connected to the fixing component. A feed component 4 is slidably mounted on the top of the connecting frame 302. The bottom of the feed component 4 is detachably connected to the transmission chain 307.

[0016] By designing a linear reciprocating mechanism, a ball bearing seat 7, a fixed plate 5, a connecting seat 6, a sprocket 306, a transmission chain 307, and a feed assembly 4, the ball bearing seat 7 is driven to move by the linear reciprocating mechanism. Since the ball bearing seat 7 is fixed on the fixed plate 5, and the fixed plate 5 is fixed on the mounting plate 103, the linear reciprocating mechanism itself moves under the interaction of forces. Since the connecting seat 6 is detachably connected to the transmission chain 307, the connecting seat 6 pulls the transmission chain 307 to run during the movement of the linear reciprocating mechanism. Furthermore, the feed assembly 4 is detachably connected to the transmission chain 307, so the operation of the transmission chain 307 will also drive the feed assembly 4 itself to move. Therefore, the movable setting of the linear reciprocating mechanism is conducive to extending out from inside the multi-axis sawing machine 1, thereby facilitating the robotic arm to grab and place the aluminum castings, and helping to reduce the interference between the aluminum castings and the multi-axis sawing machine 1 during the feeding process.

[0017] In an embodiment of the present invention, the linear reciprocating mechanism includes a motor 304 detachably disposed on one side of the side plate 301. The motor 304 is connected to a lead screw 305 rotatably mounted between the side plates 301 via a motor shaft. The ball bearing seat 7 is movably engaged with the lead screw 305.

[0018] In an embodiment of the present invention, the fixing component includes a fixing plate 5 detachably mounted on the mounting plate 103. Both sides of the upper end face of the fixing plate 5 are symmetrically and detachably mounted with connecting seats 6. The top end of the connecting seats 6 is detachably connected to the transmission chain 307.

[0019] In an embodiment of the present invention, the bottom sides of the feed assembly 4 are symmetrically and detachably equipped with connecting seats 2 10, the bottom end of the connecting seats 2 10 is detachably connected to the transmission chain 307, and the bottom sides of the feed assembly 4 are also symmetrically and detachably equipped with positioning sliders 2 9.

[0020] By designing different mechanical drive methods for the linear reciprocating mechanism and the feed assembly 4, the linear reciprocating mechanism is driven by the meshing of the lead screw 305 and the ball bearing seat 7, while the feed assembly 4 is driven by the pull of the transmission chain 307. That is, the two drive methods have different feed speeds, realizing differential feed in the same direction. This is beneficial for the feed assembly 4 to obtain a longer travel stroke, and it is also beneficial for the feed assembly 4 to be further away from the multi-axis sawing machine 1, further reducing the interference between the aluminum casting and the multi-axis sawing machine 1 during the loading process. In addition, the two drive methods use the same set of motors 304 as the drive source to achieve synchronous operation, which helps to reduce the feeding steps in the processing process and reduce maintenance costs.

[0021] In an embodiment of the present invention, positioning sliders 8 are symmetrically arranged on both sides of the upper end face of the fixing plate 5, and the positioning sliders 8 are detachably installed on the fixing plate 5.

[0022] In an embodiment of the present invention, positioning slide rails 303 can be detachably installed on both the upper and lower ends of the connecting frame 302. Positioning slider 2 9 is slidably installed on the positioning slide rail 303 located at the top of the connecting frame 302, and positioning slider 1 8 is slidably installed on the positioning slide rail 303 located at the bottom of the connecting frame 302.

[0023] The sliding cooperation between positioning slider 2 9 and positioning slider 1 8 and positioning slide rail 303 helps to improve the smoothness and stability of the linear reciprocating mechanism and the feed assembly 4 during the movement process.

[0024] Working Principle: This embodiment provides a differential feed aluminum casting sawing equipment. In use, the motor 304 is started first, and the motor shaft of the motor 304 drives the lead screw 305 to rotate. Since the ball bearing seat 7 is fixed on the fixed plate 5, and the fixed plate 5 is fixed on the mounting plate 103, the linear reciprocating mechanism itself moves under the interaction of forces. Since the connecting seat 1 6 is detachably connected to the transmission chain 307, the connecting seat 1 6 pulls the transmission chain 307 to run during the movement of the linear reciprocating mechanism. The connecting seat 2 10 is detachably connected to the transmission chain 307. Therefore, during the operation of the transmission chain 307, the feeding component 4 will be moved through the connecting seat 2 10, so that both the linear reciprocating mechanism and the feeding component 4 extend from the multi-axis saw 1, which makes it convenient for the robot arm to grab and place the aluminum casting. After placement, the motor 304 is started in reverse to realize the feeding of the aluminum casting.
