Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to a special clamp for trimming the tail of fasteners. Background Technology

[0002] In the field of precision equipment manufacturing, fasteners, as key structural connectors, directly affect assembly reliability and service life due to the geometric accuracy (form and position tolerance ≤ 0.05 mm) and surface integrity (roughness Ra ≤ 0.8 μm) of their tail (also known as the shank). Especially in high-end applications such as aerospace and precision instruments, irregularly shaped fasteners (such as stepped shafts and asymmetric threaded parts) account for more than 32% (according to GB / T16823.3-2019 statistics), and traditional clamping processes face dual technical bottlenecks. Because high-end fasteners are used in applications with high requirements for dimensions and surface quality, tail recesses and burrs need to be treated. Therefore, a special fixture is used to clamp them before processing or finishing.

[0003] Currently used traditional clamping mechanisms often lack position adjustment at the clamping end, making it difficult to clamp irregularly shaped fasteners and causing unstable fixation. Furthermore, metal shavings from the trimming process are usually difficult to clean. Therefore, a special clamp for fastener tail trimming is proposed to facilitate clamping both ends of fasteners of different lengths and sizes, further improving stability, preventing slippage, and collecting metal shavings in real time for easy worker cleanup. Utility Model Content

[0004] This invention addresses the challenges of dynamic clamping stability and chip management in the processing of irregularly shaped fastener tails. It proposes a composite clamping system with bidirectional adjustment function and an integrated chip handling device to facilitate clamping both ends of fasteners of different lengths and sizes, further improving stability, preventing slippage, and collecting iron filings in real time for easy worker cleaning.

[0005] The technical solution adopted by this utility model to solve its technical problem is a special clamp for fastener tail trimming, including a workbench, a support frame, a clamp and a storage box. The top two sides of the workbench are respectively provided with positive and negative lead screws and slide rails. The top two ends of the positive and negative lead screws and slide rails are respectively provided with support frames. The bottom of the workbench is fixed with support columns by bolts around the perimeter.

[0006] The top of the support frame is provided with a support column and a fixed column, and a clamp is provided on one side of the fixed column. The bottom of the workbench is provided with a storage box and an industrial vacuum cleaner.

[0007] Specifically, mounting slots are provided on both sides of the top of the workbench. A motor is provided on one side of the workbench, and the motor drive end is connected to the positive and negative lead screws through a rotating shaft. Both ends of the positive and negative lead screws are connected to the support frame through sliding sleeves. The bottom of the other end of the support frame is slidably connected to the slide rail through a slider.

[0008] Specifically, a connecting column is fitted onto the top of the fixing column through a pre-reserved opening, and a tightening bolt is inserted through a pre-reserved threaded hole on one side of the top of the fixing column corresponding to the bottom of the connecting column.

[0009] Specifically, an electric rotating disk is provided on one side of the connecting column, and one end of the electric rotating disk is connected to a dual-axis cylinder through a rotating shaft. The two drive ends of the dual-axis cylinder are connected to the clamp through screws.

[0010] Specifically, a buffer pad and an anti-slip pad are respectively attached to one side of the dual-axis cylinder and the other side of the clamp.

[0011] Specifically, a material unloading trough is provided between the fixtures on the top of the workbench, and a mesh is provided on the surface of the material unloading trough. A storage box is connected to the bottom of the workbench corresponding to the bottom of the material unloading trough through pipes and bolts. An industrial vacuum cleaner is installed on one side of the storage box through a reserved opening and screws.

[0012] The beneficial effects of this utility model are:

[0013] (1) The fastener tail trimming fixture described in this utility model is driven by a motor to rotate the positive and negative lead screws, thereby moving the support frames and fixtures at both ends to the sides. At the same time, the dual-axis cylinder drives the fixtures to move to the sides, which is convenient for clamping fasteners of different lengths and sizes. The dual-axis cylinder can drive the two sets of fixtures and fasteners to rotate and adjust the angle, saving workers from repeating the fixing process, processing and trimming different angles, and further improving stability and preventing fasteners from slipping.

[0014] (2) The fastener tail trimming fixture described in this utility model allows the use of an industrial vacuum cleaner to draw iron filings generated during the processing and trimming of the fastener tail into a collection box through the mesh holes on the surface of the feed trough, so that they can be collected and cleaned in a concentrated manner.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] To facilitate clamping both ends of fasteners of different lengths and sizes, further improve stability, prevent slippage, and collect metal shavings in real time for easy worker cleanup, such as... Figures 1-3 As shown, the fastener tail trimming fixture of this utility model includes a workbench 1, a support frame 6, a clamp 14 and a storage box 17. The top two sides of the workbench 1 are respectively provided with positive and negative lead screws 3 and slide rails 4. The top two ends of the positive and negative lead screws 3 and slide rails 4 are respectively provided with support frames 6. The bottom of the workbench 1 is fixed with support columns 7 by bolts around the perimeter.

[0022] The top of the support frame 6 is provided with a support column 7 and a fixing column 8, and a clamp 14 is provided on one side of the fixing column 8. The bottom of the workbench 1 is provided with a storage box 17 and an industrial vacuum cleaner 18.

[0023] In use, by adjusting the height of the fixed column 8 and the connecting column 9, the tightening bolt 10 is rotated to squeeze and fix, so as to facilitate the adjustment of the distance between the fastener and the external trimming equipment;

[0024] The motor 5 is turned on to drive the positive and negative lead screws 3 to rotate, thereby moving the support frames 6 at both ends and the clamps 14 to both sides, clamping the ends of fasteners of different lengths, further improving stability and preventing the fasteners from slipping off.

[0025] After the dual-axis cylinder 12 drives the clamp 14 to move to both sides to adjust the clamping of fasteners of different sizes, the dual-axis cylinder 12 can drive the two sets of clamps 14 and the fasteners to rotate and adjust the angle, saving workers from repeating the fixing process and processing and trimming different angles.

[0026] When the clamp 14 clamps and fixes the fastener, the buffer pad 13 and the anti-slip pad 15 are pressed against both sides, increasing the friction of the contact surface and preventing slippage during processing, thus preventing the fastener from falling out of the clamp 14.

[0027] Then turn on the industrial vacuum cleaner 18 and suck the iron filings generated when processing and trimming the tail of the fastener into the collection box 17 through the mesh on the surface of the feed trough 16, so that they can be collected and cleaned up.

[0028] To increase the clamping force, for example, such as Figure 1 , Figure 2 As shown, this utility model also includes mounting slots 2 on both sides of the top of the workbench 1, a motor 5 on one side of the workbench 1, and the driving end of the motor 5 is connected to the positive and negative lead screws 3 through a rotating shaft. The top two ends of the positive and negative lead screws 3 are connected to the support frame 6 through sliding sleeves, and the bottom of the other end of the support frame 6 is slidably connected to the slide rail 4 through a slider.

[0029] In use, the motor 5 drives the positive and negative lead screws 3 to rotate, thereby moving the support frames 6 at both ends and the clamps 14 to clamp the ends of fasteners of different lengths, ensuring stability.

[0030] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes a connecting column 9 sleeved on the top of the fixing column 8 through a reserved opening, and a tightening bolt 10 passing through a reserved threaded hole on one side of the top of the fixing column 8 corresponding to the bottom of the connecting column 9.

[0031] During use, the height of the fixed column 8 and the connecting column 9 are adjusted, and the tightening bolt 10 is rotated to squeeze and fix them, so as to facilitate the adjustment of the distance between the fastener and the external trimming equipment.

[0032] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes an electric rotating disk 11 on one side of the connecting column 9, one end of the electric rotating disk 11 being connected to a dual-axis cylinder 12 via a rotating shaft, and the two driving ends of the dual-axis cylinder 12 being connected to the clamp 14 via screws.

[0033] In use, the dual-axis cylinder 12 drives the clamps 14 to move relative to each other, so as to facilitate the clamping of fasteners of different sizes. Then, the dual-axis cylinder 12 can drive the two sets of clamps 14 and the fasteners to rotate and adjust the angle, saving workers from repeating the fixing process and processing and trimming different angles.

[0034] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes a buffer pad 13 and an anti-slip pad 15 respectively adhered to one side of the dual-axis cylinder 12 and the other side of the clamp 14.

[0035] When the clamp 14 clamps and fixes the fastener, the buffer pad 13 and the anti-slip pad 15 are pressed against the sides, increasing the friction of the contact surface and preventing slippage during processing, thus preventing the fastener from falling out of the clamp 14.

[0036] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a material unloading groove 16 opened between the top of the workbench 1 and the clamp 14, the surface of the material unloading groove 16 being provided with mesh holes, and the bottom of the workbench 1 corresponding to the bottom of the material unloading groove 16 being connected to a storage box 17 via pipes and bolts, and an industrial vacuum cleaner 18 being installed on one side of the storage box 17 via a reserved opening and screws.

[0037] When in use, the industrial vacuum cleaner 18 is turned on and sucks the iron filings generated when processing and trimming the tail of the fastener into the collection box 17 through the mesh on the surface of the feed trough 16 via the pipe, so that they can be collected and cleaned up.

[0038] In use, this utility model allows for easy adjustment of the distance between the fasteners and the external trimming equipment by adjusting the height of the fixed column 8 and the connecting column 9, and by rotating and tightening the bolt 10 to compress and fix them.

[0039] The motor 5 is turned on to drive the positive and negative lead screws 3 to rotate, thereby moving the support frames 6 at both ends and the clamps 14 to both sides, clamping the ends of fasteners of different lengths, further improving stability and preventing the fasteners from slipping off.

[0040] After the dual-axis cylinder 12 drives the clamp 14 to move to both sides to adjust the clamping of fasteners of different sizes, the dual-axis cylinder 12 can drive the two sets of clamps 14 and the fasteners to rotate and adjust the angle, saving workers from repeating the fixing process and processing and trimming different angles.

[0041] When the clamp 14 clamps and fixes the fastener, the buffer pad 13 and the anti-slip pad 15 are pressed against both sides, increasing the friction of the contact surface and preventing slippage during processing, thus preventing the fastener from falling out of the clamp 14.

[0042] Then turn on the industrial vacuum cleaner 18 and suck the iron filings generated when processing and trimming the tail of the fastener into the collection box 17 through the mesh on the surface of the feed trough 16, so that they can be collected and cleaned up.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
