[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Please see Figure 1 - Figure 8 A deburring fixture for die-cast parts includes a frame 1 and a vibrating feeder 2, the vibrating feeder 2 being mounted on the frame 1, and further includes: The grinding mechanism 3 is installed inside the frame 1; The feeding channel 4 is set on the frame 1, and the vibrating feeder 2 vibrates and feeds the material block into the feeding channel 4; The moving channel 5 is set on the frame 1, and the moving channel 5 is equipped with a clamping mechanism 6. The material block is moved to the moving channel 5 through the feeding channel 4. The material block transfer mechanism 7 is installed on the frame 1. The material block transfer mechanism 7 includes a fork 71 and a drive component 72. The fork 71 is provided with a number of slots 73. The drive component 72 drives the fork 71 to reciprocate inside the frame 1 so that the fork 71 can be inserted into the material block. The material block is then moved to the clamping mechanism 6 by the fork 71 and polished by the polishing mechanism 3.

[0020] Specifically, the vibrating feeder 2 is a conventional feeding device in the prior art. It feeds the material blocks by vibration. The specific working principle and structure of the vibrating feeder 2 will not be described in detail here.

[0021] It should be noted that the hopper inside the vibrating feeder 2 is specially designed to ensure the vibrating conveying direction of the material blocks, so as to facilitate subsequent processing. The vibrating feeder 2 can control the direction of material conveying through vibration, which is existing technology, and its principle will not be elaborated here.

[0022] As an embodiment provided by this utility model, such as Figure 1 As shown, one end of the feeding channel 4 is connected to the vibrating feeder 2. The vibrating feeder 2 vibrates the material blocks in the hopper and feeds them into the feeding channel 4.

[0023] Inside the frame 1, there is also a moving channel 5, which is connected to the feeding channel 4. The material block is vibrated and fed into the feeding channel 4 by the vibrating feeder 2, and then transferred to the moving channel 5 through the feeding channel 4.

[0024] As an embodiment provided by this utility model, such as Figure 1 As shown, a material block transfer mechanism 7 is provided inside the frame 1. Specifically, the material block transfer mechanism 7 includes a shift fork 71 and a drive component 72. The drive component 72 is mounted on the frame 1, and the shift fork 71 is connected to the output end of the drive component 72. The drive component 72 can drive the shift fork 71 to move inside the frame 1. Several slots 73 are provided on the shift fork 71. The shape of the slots 73 is adapted to the shape of the material block. The drive component 72 drives the shift fork 71 to move inside the frame 1, pushing the material block to move inside the moving channel 5. There are several slots 73, which are arranged in a linear array on the shift fork 71 so as to drive multiple material blocks to move simultaneously.

[0025] A clamping mechanism 6 is provided on the moving channel 5. The material block can be clamped in the moving channel 5 by the clamping mechanism 6, and then the burrs on specific edges of the material block are removed by the grinding mechanism 3.

[0026] This utility model uses a vibrating feeder 2 to vibrate the material block into the feeding channel 4 and then transport it to the moving channel 5. The drive component 72 of the material block transfer mechanism 7 drives the shift fork 71 to transfer the material block to the clamping mechanism 6, where it is clamped. Finally, the grinding mechanism 3 removes the burrs from the material block. This invention enables automatic loading and unloading of material blocks and automatic grinding, greatly improving the efficiency of burr removal, increasing economic benefits, and reducing manual labor intensity.

[0027] As an embodiment provided by this utility model, such as Figure 8As shown, the clamping mechanism 6 includes a clamping cylinder 61 and a clamping block 62.

[0028] As an embodiment of the present invention, there are two clamping mechanisms 6, which are arranged in a linear array inside the frame 1.

[0029] As an embodiment provided by this utility model, such as Figure 7 As shown, a positioning mechanism 51 is provided on the moving channel 5. The position and number of positioning mechanisms 51 are adapted to the clamping mechanism 6. The positioning mechanism 51 includes a positioning block 511, which clamps the material block in the moving channel 5 through the positioning block 511 and the clamping mechanism 6.

[0030] Furthermore, the positioning mechanism 51 also includes a limiting block 512 and an elastic unit 513. A groove is provided on the outer wall of the moving channel 5. The positioning block 511 is slidably connected in the groove. The limiting block 512 is fixedly installed on the outer wall of the moving channel 5.

The positioning block 511 is slidably connected to the limiting block 512. The elastic unit 513 can drive the positioning block 511 to move into the moving channel 5 and abut against the material block.

[0031] During processing, the shift fork 71 pushes the material block between the clamping mechanism 6 and the positioning mechanism 51. The clamping cylinder 61 drives the clamping block 62 to move toward the material block, and the clamping inclined surface 63 on the clamping block 62 abuts against the arc surface on the material block, thereby clamping the material block. When the clamping block 62 abuts against the arc surface, the movable positioning block 511 can abut against the material block and push the positioning block 511 to slide outward to adapt to the edge defects of the material block itself. Finally, it can move past the limit block 512 to limit the position, so as to ensure that the material block can be fully clamped.

[0032] As a further embodiment provided by this utility model, such as Figure 6As shown, the drive component 72 includes a longitudinal drive unit 721, a longitudinal slider 722, and a longitudinal slide rail 723.

The longitudinal drive unit 721 can drive the longitudinal slider 722 to move along the longitudinal slide rail 723, thereby driving the shift fork 71 to move inside the frame 1.

[0033] As a further embodiment provided by this utility model, such as Figure 3 As shown, a transverse drive assembly 74 is provided on the longitudinal slider 722. The transverse drive assembly 74 includes a transverse drive unit 741 and a transverse slider 742. The transverse drive unit 741 is fixedly connected to the longitudinal slider 722.

The transverse slider 742 is connected to the shift fork 71. The shift fork 71 is slidably connected to the longitudinal slider 722. The transverse drive unit 741 can drive the transverse slider 742 to move toward the moving channel 5, thereby driving the shift fork 71 to move toward the moving channel 5, so that the slot 73 on the shift fork 71 can abut against the material blocks at different positions in the moving channel 5.

[0034] As an embodiment provided by this utility model, such as Figure 4 and Figure 5 As shown, the grinding mechanism 3 includes a reciprocating motion mechanism 31 and a lifting motion mechanism 32. The reciprocating motion mechanism 31 includes a reciprocating drive unit 311 and a reciprocating slider 312. Specifically, the reciprocating drive unit 311 is a stepper motor. The reciprocating drive unit 311 is mounted on the frame 1, and the reciprocating slider 312 is slidably connected to the frame 1. The output end of the reciprocating drive unit 311 is connected to the reciprocating slider 312. The reciprocating drive unit 311 can drive the reciprocating slider 312 to maintain reciprocating motion on the frame 1. Preferably, the reciprocating motion mechanism 31 also includes a transverse base 313 and a threaded block. 3 is fixedly connected to the frame 1. The reciprocating slider 312 is slidably connected to the transverse base 313. That is, the reciprocating slider 312 is slidably connected to the frame 1 through the transverse base 313. The reciprocating drive unit 311 is fixedly connected to the transverse base 313. The reciprocating drive unit 311 is fixedly connected to the frame 1 through the transverse base 313. A screw is connected to the output end of the reciprocating drive unit 311. The threaded block is fixedly connected to the reciprocating slider 312. The reciprocating drive unit 311 drives the screw to keep rotating and pushes the threaded block to move, so as to achieve the purpose of driving the reciprocating slider 312 to keep reciprocating on the frame 1.

[0035] Furthermore, the lifting motion mechanism 32 is disposed on the reciprocating slider 312, and a vertical support 314 is fixedly installed on the reciprocating slider 312. The lifting motion mechanism 32 is connected to the reciprocating slider 312 through the vertical support 314. Specifically, the lifting motion mechanism 32 includes a lifting drive unit 321, a lifting base 322, and a lifting slider 323. The lifting base 322 is fixedly connected to the vertical support 314, and the lifting drive unit 321 is fixedly installed on the lifting base 322. The lifting drive unit 321 is a stepper motor. A screw is connected to the output end of the lifting drive unit 321, and a threaded block is fixedly connected to the lifting slider 323. The screw meshes with the threaded block. The output end of the lifting drive unit 321 drives the screw to rotate, thereby driving the lifting slider 323 to move up and down on the lifting base 322. The grinding motor 33 is fixedly connected to the lifting slider 323. Specifically, there are two grinding motors 33, and one of the grinding motors 33 can be connected to the lifting slider 323 through a pad to ensure that different parts of the material block can be ground.

[0036] As an embodiment provided by this utility model, such as Figure 6 and Figure 4 As shown, a pushing mechanism 41 is provided at the end of the feeding channel 4. Specifically, the pushing mechanism 41 includes an ejector block 411, a pushing drive unit 412 fixedly mounted on the frame 1, and a positioning seat 413. The pushing drive unit 412 is specifically a cylinder. The ejector block 411 is slidably connected to the positioning seat 413. A positioning groove 414 is provided inside the positioning seat 413. One end of the positioning groove 414 is connected to the moving channel 5, and the other end is connected to the feeding channel 4. The output end of the pushing drive unit 412 is connected to the ejector block 411.

[0037] Working principle: When in use, first start the vibrating feeder 2. The material block in the hopper inside the vibrating feeder 2 is vibrated and fed into the feeding channel 4. A vertical vibrator 11 is also installed on the frame 1 to drive the material block in the feeding channel 4. Then the material block enters the feeding channel 4. The material block moves into the positioning groove 414 of the positioning seat 413 of the pushing mechanism 41 under the action of the vertical vibrator 11, and then the push drive unit 412 drives the ejector block 411 to eject the material block into the moving channel 5.

[0038] At this time, the longitudinal drive unit 721 is activated. The output end of the longitudinal drive unit 721 pushes the longitudinal slider 722 to move along the longitudinal slide rail 723, thereby driving the shift fork 71 to move inside the frame 1. After the shift fork 71 moves into place, the transverse drive unit 741 is activated to drive the shift fork 71 to move toward the moving channel 5, so that the slot 73 on it abuts against the material block. Then the longitudinal drive unit 721 drives the longitudinal slider 722 to reset, and pushes the material block to move inside the moving channel 5 through the slot 73.

[0039] When the material block is pushed between the clamping mechanism 6 and the positioning mechanism 51, the transverse drive unit 741 resets and drives the shift fork 71 to reset. After the shift fork 71 resets, under the drive of the longitudinal drive unit 721, one of the slots 73 is repositioned at the push mechanism 41. At the same time, the clamping cylinder 61 is activated. The output end of the clamping cylinder 61 pushes the clamping block 62 to move towards the material block. The clamping inclined surface 63 on the clamping block 62 abuts against the arc surface on the material block, clamping the material block. At this time, the movable positioning block 511 can abut against the material block and push the positioning block 511 to slide outward to adapt to the edge defects of the material block itself. Finally, the limiting block 512 limits the position, ensuring that the material block can be completely clamped.

[0040] Then, the reciprocating motion mechanism 31 and the lifting motion mechanism 32 are started, and the position of the grinding motor 33 is adjusted. The grinding motor 33 grinds the material block to remove burrs. After grinding is completed, the clamping cylinder 61 is reset, which resets the clamping block 62. Then, the shift fork 71, driven by the transverse drive unit 741, re-clamps the material block inside the moving channel 5. Since the shift fork 71 is provided with multiple slots 73, it can simultaneously drive multiple material blocks to move in the moving channel 5 for the next process.

[0041] The drive unit 412 is activated, causing the ejector block 411 to slide inside the positioning seat 413, pushing the next material block to be processed in the feeding channel 3 into the moving channel 5, where it awaits the push of the shift fork 71. When the shift fork 71 pushes, the processed material block is discharged through the discharge port set on the frame 1. This cycle is repeated, realizing automated deburring of die-cast parts, improving processing efficiency and processing quality.

[0042] The compression spring mentioned in this article has an elastic coefficient that meets the technical requirements of this utility model.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
