Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically to a trimming device for aluminum alloy casting production. Background Technology

[0002] During the production of aluminum alloy castings, the closing of the mold and the injection of molten metal often result in excess burrs and flash at the edges of the castings. These excess parts not only affect the appearance quality of the castings but may also affect their dimensional accuracy and subsequent machining performance. Therefore, specialized trimming equipment is needed to remove these excess parts.

[0003] A search revealed a utility model patent with Chinese patent publication number CN215787071U, which discloses a cutting device for aluminum alloy casting production, comprising a machine body, a crossbeam, connecting blocks, and a collection box. A gantry frame is fixed to the rear end of the upper surface of the machine body, and fixing blocks are fixed to both sides of the front of the gantry frame. Lead screws are fixed to the front ends of the two fixing blocks, and lead screw nuts movably installed inside the two lead screws are fixed to both ends of the crossbeam. A track is embedded in the front of the crossbeam.

[0004] After the above-mentioned device completes the cutting work, the finished product needs to be removed from the top of the workbench before a new casting can be placed. If the casting is large in size and mass, the removal process will be time-consuming, which is not conducive to improving processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a trimming device for aluminum alloy casting production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trimming device for aluminum alloy casting production, comprising an installation table, a receiving component installed inside the installation table, the receiving component including an installation groove on the top outer wall of the installation table, a horizontally arranged receiving plate hinged inside the installation groove, two sliding grooves on one side of the top outer wall of the installation table, and a support seat placed at the bottom of each sliding groove, both support seats being trapezoidal in shape, and an extension portion on one side of each support seat, an extension column fixedly connected to the outer walls of both ends of the receiving plate, the two extension columns respectively contacting the two support seats, and a through groove on one side of the bottom inner wall of the installation table, the through groove being located at the bottom of the movable end of the receiving plate.

[0007] As a further preferred embodiment of this technical solution, two telescopic rods are fixedly connected to the other side of the two support seats. One end of each of the two telescopic rods is fixedly connected to the inner wall of the slide groove, and a spring is sleeved on the outside of each of the four telescopic rods.

[0008] As a further preferred embodiment of this technical solution, two support frames are fixedly connected to the top outer wall of the mounting table. A linear motor is fixedly installed on the top inner wall of each of the two support frames. A cutting assembly is installed at the bottom of the two linear motors. The cutting assembly includes the same mounting frame to which the two linear motor actuators are fixedly connected. Two push plates are fixedly connected to the outer wall of one side of the mounting frame. The positions of the two push plates are respectively opposite to the positions of the two support seats.

[0009] After the aluminum alloy casting has been trimmed, the receiving plate can be tilted to achieve automatic material discharge, saving time and improving work efficiency. When the mounting frame moves to the end of the mounting slot, the external push plate contacts the extension of the support base. The spring connected to the support base is compressed and shortened, and the bottom of the extension column loses support. Under the action of gravity, the extension column will move down along the slope of the support base. Then the tilt angle of the receiving plate gradually increases, and the casting on it will slide off to the outside. Only a receiving device needs to be placed outside. When the push plate moves away from the support base, the spring will drive the support base back to its original position, facilitating the next operation.

[0010] As a further preferred embodiment of this technical solution, a horizontally arranged bidirectional lead screw is rotatably connected inside the mounting frame. A vertically arranged cutting machine is threaded to both ends of the bidirectional lead screw, and the two cutting machines are respectively located at both ends of the receiving plate. Two horizontally arranged limiting rods are fixedly connected inside the mounting frame, and the two cutting machines are slidably sleeved on the outside of the two limiting rods.

[0011] The linear motor inside the support frame is started. The mover of the linear motor drives the mounting frame to move. When the cutting machine at the bottom of the mounting frame moves over the casting, the edge of the casting will be cut off. If the required cutting size changes, the turntable drives the bidirectional lead screw to rotate. The cutting machine, which is restricted by the limit rod, will be driven to move in opposite directions by the bidirectional lead screw, and the size of the processed part will gradually change, making it more adaptable.

[0012] As a further preferred embodiment of this technical solution, a second support frame is fixedly connected to one side of the outer wall of the top of the mounting table, and a vertically arranged hydraulic cylinder is fixedly installed inside the second support frame, with a pressure plate provided at the output end of the hydraulic cylinder.

[0013] As a further preferred embodiment of this technical solution, the bottom wall of the mounting table is set as an inclined surface, and a horizontally arranged chip discharge port is opened on the outside of the mounting table, the chip discharge port corresponding to the bottom position of the inclined surface.

[0014] As a further preferred embodiment of this technical solution, the thread helix angle at both ends of the bidirectional lead screw is less than the equivalent friction angle.

[0015] This utility model provides a trimming device for aluminum alloy casting production, which has the following advantages:

[0016] (1) By setting up a receiving component, this utility model can make the receiving plate in an inclined state after the aluminum alloy casting has completed the edge cutting work, so that the automatic material discharge can be realized, making the operation more time-saving and improving work efficiency. When the mounting frame moves to the end of the mounting groove, its external push plate contacts the extension part of the support seat, the spring connected to the support seat is compressed and shortened, the bottom of the extension column loses support, and under the action of gravity, the extension column will move down along the inclined surface of the support seat. Then the inclination angle of the receiving plate gradually increases, and the casting on it will slide to the outside by itself. As long as the receiving equipment is placed outside, when the push plate moves away from the support seat, the spring will drive the support seat back to its original position, which is convenient for the next work.

[0017] (2) By setting up a cutting component, the linear motor inside the support frame is started. The moving part of the linear motor drives the mounting frame to move. When the cutting machine at the bottom of the mounting frame moves past the casting, the edge of the casting will be cut off. If the required cutting size changes, the double screw is driven to rotate by the turntable. The cutting machine, which is limited by the limit rod, will be driven to move in opposite directions by the double screw, and the size processed will gradually change, making it more adaptable.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 , Figure 2 As shown in Figure 4, in this embodiment, a trimming device for aluminum alloy casting production includes a mounting table 1. A receiving component 7 is installed inside the mounting table 1. The receiving component 7 includes a mounting groove 701 opened on the top outer wall of the mounting table 1. A horizontally arranged receiving plate 702 is hinged inside the mounting groove 701. Two sliding grooves are provided on one side of the top outer wall of the mounting table 1, and a support seat 705 is placed at the bottom of each of the two sliding grooves. Both support seats 705 are trapezoidal in shape, and an extension portion is provided on one side of each support seat 705. An extension column 703 is fixedly connected to the outer walls of both ends of the receiving plate 702. The two extension columns 703 are in contact with the two support seats 705 respectively. A through groove is provided on one side of the bottom inner wall of the mounting table 1, and the through groove is located at the bottom of the movable end of the receiving plate 702.

[0025] Two telescopic rods 704 are fixedly connected to the other side of the two support seats 705. One end of each telescopic rod 704 is fixedly connected to the inner wall of the slide groove, and a spring 706 is sleeved on the outside of each of the four telescopic rods 704.

[0026] like Figure 1 As shown, two support frames 3 are fixedly connected to the top outer wall of the mounting table 1. A linear motor 4 is fixedly installed on the top inner wall of each of the two support frames 3. A cutting assembly 8 is installed at the bottom of the two linear motors 4. The cutting assembly 8 includes the same mounting frame 801 with the movers of the two linear motors 4 fixedly connected. Two push plates 707 are fixedly connected to one side outer wall of the mounting frame 801. The positions of the two push plates 707 are respectively opposite to the positions of the two support seats 705.

[0027] When the mounting frame 801 moves to the end of the mounting slot 701, the push plate 707 on its outside contacts the extension of the support base 705. The spring 706 connected to the support base 705 is compressed and shortened by the force, and the bottom of the extension column 703 loses support. Under the action of gravity, the extension column 703 will move down along the inclined surface of the support base 705. Then the tilt angle of the receiving plate 702 gradually increases, and the casting on it will slide down to the outside by itself. It is only necessary to place a receiving device outside. When the push plate 707 moves away from the support base 705, the spring 706 will drive the support base 705 back to its original position, which is convenient for the next operation.

[0028] like Figure 1 and Figure 3As shown, a horizontally arranged bidirectional lead screw 802 is rotatably connected inside the mounting frame 801. A vertically arranged cutting machine 804 is threaded to both ends of the bidirectional lead screw 802. The two cutting machines 804 are located at both ends of the receiving plate 702. Two horizontally arranged limiting rods 803 are fixedly connected inside the mounting frame 801. The two cutting machines 804 are slidably sleeved on the outside of the two limiting rods 803.

[0029] The linear motor 4 inside the support frame 3 is started. The mover of the linear motor 4 drives the mounting frame 801 to move. When the cutting machine 804 at the bottom of the mounting frame 801 moves past the casting, the edge of the casting will be cut off. If the required cutting size changes, the double-acting screw 802 is rotated by the turntable. The cutting machine 804, which is limited by the limit rod 803, will be driven to move in the opposite direction by the double-acting screw 802, and the size processed will gradually change, making it more adaptable.

[0030] like Figure 2 As shown, a support frame 2 5 is fixedly connected to one side of the top outer wall of the mounting table 1. A vertically arranged hydraulic cylinder 6 is fixedly installed inside the support frame 2 5. A pressure plate is provided at the output end of the hydraulic cylinder 6. When the hydraulic cylinder 6 inside the support frame 2 5 is activated, the output end of the hydraulic cylinder 6 drives the pressure plate to press against the top of the casting. With the cooperation of the receiving plate 702, the casting can be fixed and its displacement during processing can be prevented.

[0031] like Figure 1 As shown in Figure 2, the bottom wall of the mounting table 1 is set as an inclined surface, and a horizontally set chip discharge port 2 is opened on the outside of the mounting table 1. The chip discharge port 2 corresponds to the bottom position of the inclined surface. The chips generated during the cutting process are driven and ejected into the interior of the mounting table 1. Since the bottom wall of the mounting table 1 is inclined, the chips will slide down along the inclined bottom wall to the bottom and finally slide out of the chip discharge port 2 to the outside.

[0032] like Figure 3 As shown, the thread helix angle at both ends of the bidirectional lead screw 802 is less than the equivalent friction angle, which enables it to have a self-locking property, thereby ensuring that the position of the cutting machine 804 connected to it will not change arbitrarily after the adjustment is completed.

[0033] This utility model provides a trimming device for aluminum alloy casting production, the specific working principle of which is as follows:

[0034] When the device is working, the hydraulic cylinder 6 inside the support frame 2 5 is activated. The output end of the hydraulic cylinder 6 drives the pressure plate to press against the top of the casting. Together with the receiving plate 702, the casting can be fixed to prevent displacement during processing. The linear motor 4 inside the support frame 1 3 is activated. The mover of the linear motor 4 drives the mounting frame 801 to move. When the cutting machine 804 at the bottom of the mounting frame 801 moves past the casting, the edge of the casting will be cut off. If the required cutting size changes, the double-acting screw 802 is rotated by the turntable. The cutting machine 804, which is limited by the limit rod 803, will be driven by the double-acting screw 802 to move in opposite directions, and the processed size will gradually change, making it more adaptable. When the mounting frame 801 moves to the end of the mounting groove 701, its outer... The push plate 707 of the part contacts the extension of the support base 705. The spring 706 connected to the support base 705 is compressed and shortened by force. The bottom of the extension column 703 loses support. Under the action of gravity, the extension column 703 will move down along the inclined surface of the support base 705. Then the tilt angle of the receiving plate 702 gradually increases, and the casting on it will slide down to the outside by itself. It is only necessary to place a receiving device outside. When the push plate 707 moves away from the support base 705, the spring 706 will drive the support base 705 back to its original position, which is convenient for the next operation. In addition, the chips generated during the cutting process are driven and ejected into the interior of the mounting table 1. Since the bottom wall of the mounting table 1 is inclined, the chips will slide down along the inclined bottom wall to the bottom and finally slide down to the outside from the chip discharge port 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
