Description

Technical Field

[0001] This utility model relates to the technical field of pre-compression devices, and in particular to a toothed pre-compression device. Background Technology

[0002] In machining processes, fixtures are often used to grip workpieces. However, existing fixtures are prone to slippage and instability during subsequent machining as the applied force increases, leading to reduced machining accuracy and lower yield. To improve this, pre-pressed tooth marks can be made on the workpiece, and corresponding teeth can be added to the fixture. The teeth on the fixture cooperate with the tooth marks on the workpiece to increase the gripping friction of the fixture, thereby improving the stability of the workpiece during machining.

[0003] Most existing pre-compression devices can only pre-compress workpieces with small mass and low hardness. Large workpieces are larger than small workpieces in both mass and hardness. Also, the forces exerted on large workpieces during processing are much greater than those on small workpieces. Therefore, in the absence of appropriate pre-compression equipment, large workpieces are often pre-compressed by manual labor in conjunction with machines. This is cumbersome, has low pre-compression accuracy, and is prone to errors, resulting in mismatch between the tooth marks and the bite teeth on the workpiece. Therefore, improvements are needed.

[0022] like Figures 1 to 2As shown, a pre-compression device for toothed teeth includes a pre-compression machine platform 10. The pre-compression machine platform 10 is provided with a first pre-compression tooth mold 20, a second pre-compression tooth mold 30, and a pre-compression drive member 40. The pre-compression machine platform 10 is provided with a pre-compression space, and a pre-compression slide rail 11 is provided in the pre-compression space. The first pre-compression tooth mold 20 and the second pre-compression tooth mold 30 are respectively disposed opposite to each other at both ends of the pre-compression slide rail 11. The pre-compression drive member 40 is connected to the first pre-compression tooth mold 20 and / or the second pre-compression tooth mold 30 in a transmission connection, and the pre-compression drive member 40 drives the first pre-compression tooth mold 20 and / or the second pre-compression tooth mold 30 to move closer to or further away from each other. By setting a fixed first pre-compression toothed mold 20 and a movable second pre-compression toothed mold 30 on the machine base, when performing pre-compression operation on the workpiece, the workpiece to be pre-compressed is first placed on the processing station of the pre-compression machine base 10. The second pre-compression toothed mold 30 is pushed by the pre-compression drive 40. The workpiece is pre-compressed by the interlocking movement of the first pre-compression toothed mold 20 and the second pre-compression toothed mold 30, which facilitates efficient pre-compression of large workpieces and facilitates subsequent processing of the workpiece. After the pre-compression is completed, the second pre-compression toothed mold 30 is reset by the pre-compression drive 40, which facilitates the removal of the workpiece.

[0023] The first pre-compression toothed mold 20 is fixedly mounted on the pre-compression machine base 10, and the second pre-compression toothed mold 30 is movably mounted on the pre-compression machine base 10. The pre-compression drive component 40 is connected to the second pre-compression toothed mold 30 via a transmission connection. In this embodiment, the first pre-compression toothed mold 20 is fixedly connected to the pre-compression machine base 10, and the second pre-compression toothed mold 30 is movably connected to the pre-compression machine base 10 via a pre-compression slide rail 11. The pre-compression drive component 40 drives the second pre-compression toothed mold 30 to move closer to or further away from the first pre-compression toothed mold 20, thereby facilitating the pre-compression of the workpiece or facilitating the separation of the workpiece from the pre-compression machine base 10 after pre-compression.

[0024] The first pre-compression die 20 includes a fixed die block 21. A fixed die mounting groove is provided at the end of the pre-compression slide rail 11 on the pre-compression machine platform 10.

A first pre-compression block 22 is provided on the side of the fixed die block 21 facing the second pre-compression die 30, and the first pre-compression block 22 is fixedly connected to the fixed die block 21. In this embodiment, by providing a fixed die mounting groove on the pre-compression machine platform 10 and an assembly protrusion on the fixed die block 21, the fixed die block 21 is fixedly connected to the pre-compression machine platform 10 through the engagement of the assembly protrusion with the fixed die mounting groove. This also facilitates quick identification of the assembly position of the fixed die block 21 during assembly, improving installation efficiency. The first pre-compression block 22 on the fixed die block 21 facilitates pre-compression of the workpiece by the teeth.

[0025] A workpiece limiter 23 is provided on the fixed mold block 21, and the workpiece limiter 23 is located on the side adjacent to the first pre-compression block 22.

[0026] A safety baffle 24 is provided at the upper end of the fixed mold block 21. In this embodiment, a safety baffle 24 is provided on the fixed mold block 21. The safety baffle 24 is used to safely block the workpiece during the processing and prevent the workpiece from flying out of the pre-pressing machine 10 during the biting pre-pressing process. The safety baffle 24 is used to avoid risks and improve the safety of the pre-pressing device.

[0027] The second pre-compression die 30 includes a movable die stop 31, a pre-compression slider slidably disposed on the pre-compression slide rail 11, the movable die stop 31 being connected to the pre-compression slider, and a second pre-compression block 32 disposed on the side of the movable die stop 31 opposite to the first pre-compression die 20. A pre-compression drive 40 is drively connected to the movable die stop 31. In this embodiment, by slidably disposing of the pre-compression slider on the pre-compression slide rail 11, and connecting the movable die stop 31 to the pre-compression slider, in conjunction with the pre-compression drive 40, the movable die stop 31 is controlled and connected, thereby facilitating the movement of the second pre-compression block 32 toward the first pre-compression block 22 to perform pre-compression teeth on the workpiece.

[0028] A fine-tuning component 41 is provided on the pre-pressure drive component 40, and an assembly end is provided on the second pre-pressure block 32. The second pre-pressure block 32 is connected to the fine-tuning component 41 on the pre-pressure drive component 40 via the assembly end. In this embodiment, the fine-tuning component 41 is used to adjust the initial relative position of the second pre-pressure block 32 and the first pre-pressure block 22, thereby facilitating adjustment according to parameters such as the size and material of the workpiece and the depth of the pre-pressure teeth, and improving the compatibility of the teeth pre-pressure device.

[0029] The pre-compression drive component 40 includes a drive module 42 and a fixing module 43. The fixing module 43 is fixedly mounted on the pre-compression machine base 10.

A hydraulic drive component is provided on the fixing module 43, and a hydraulic drive space is provided on the fixing module 43. One end of the drive module 42 is located in the hydraulic drive space. In this embodiment, by cooperating with an external hydraulic device, the drive module 42 is driven to move within the hydraulic drive space, thereby driving the movable mold stop 31 to move on the pre-compression slide rail 11, thereby realizing the pre-compression engagement or release and removal of the workpiece.

[0030] A reset space is provided between the drive module 42 and the fixed module 43, and a reset spring 44 is provided within the reset space. The two ends of the reset spring 44 are respectively attached to the drive module 42 and the fixed module 43.

[0031] The fixed module 43 is provided with an air exchange channel 45, which is connected to the reset space. In this embodiment, the fixed module 43 is provided with an air exchange channel 45 to facilitate the connection between the reset space and the outside air, thereby improving the reset accuracy of the reset spring 44.
