Description

Technical Field

[0001] This new type belongs to a processing device, and specifically relates to a clamping device for processing the slotted heads of a batch of screws. Background Art

[0002] Hexagon socket head cap screws are commonly used parts in the mechanical field. The end faces of commercially available hexagon socket head cap screws do not have slotted heads. However, in some special fields, it is necessary to open slotted heads on the end faces of hexagon socket head cap screws. Under normal circumstances, the slotted heads can be processed one by one by mechanical processing methods. However, if the number of slotted heads to be processed is large and the screws are small, the processing efficiency is low, and the threads are easily damaged.

[0003] Therefore, a device that can process slotted heads in batches is needed. Summary of the Utility Model

[0004] Aiming at the defects of the prior art, this new type provides a clamping device for processing the slotted heads of a batch of screws.

[0005] This new type is realized as follows: A clamping device for processing the slotted heads of a batch of screws, which includes a flat tooling. A number of holes are opened on the flat tooling, and a sizing tube is arranged in each hole.

[0006] In the clamping device for processing the slotted heads of a batch of screws as described above, all the sizing tubes are arranged on the same side of the flat tooling.

[0007] In the clamping device for processing the slotted heads of a batch of screws as described above, the lengths of all the sizing tubes match the lengths of the hexagon socket head cap screws, so that the end faces of the hexagon socket head cap screws protrude from the flat tooling.

[0008] In the clamping device for processing the slotted heads of a batch of screws as described above, the inner wall of the sizing tube is provided with threads, and the threads match the threads of the hexagon socket head cap screws.

[0009] In the clamping device for processing the slotted heads of a batch of screws as described above, all the sizing tubes are arranged in a row, which is convenient for processing the end faces of multiple hexagon socket head cap screws at one time.

[0010] The remarkable effect of this new type is that the design is simple, reasonable, compact and easy to install. Through the screwing clamping force of the screws in the threaded holes of the flat tooling, a batch of screws are clamped into the flat tooling. Through actual processing and verification of the processed workpieces, this clamping device meets the usage requirements. Description of the Drawings

[0017] In the figure: 1. Flat tool, 2. Fixed-distance tube, 3. Allen screw. Specific implementation method

[0018] A clamping device for processing the slotted heads of a batch of screws. Using the thread of the Allen screw 3, a fixed-length fixed-distance tube 2 is sleeved at the screw thread, and then the screw is screwed into the threaded hole of the tool. The screw is tightened to the tool with an Allen wrench, so that the screw tightly presses the sleeve to increase the axial force after the screw thread and the threaded hole thread of the tool are engaged, preventing the screw from rotating. At the same time, the end of the screw thread extends a certain length out of the outlet end of the tool to ensure that the subsequent processing of the slotted head of the screw with a 2mm thick saw blade does not interfere. The specific structure and working principle of the clamping device are as follows:

[0019] a. The clamping device consists of a flat tool 1 and a fixed-distance tube, as shown in Figures 2a - 2c .

[0020] b. The flat tool 1 is processed with a certain number of threaded holes that are the same as the screw thread at the same horizontal height and the same column pitch for screwing in a batch of screws.

[0021] c. The length of the fixed-distance tube 2 needs to meet the requirement that after the screw is screwed into the threaded hole of the flat tool 1, it extends a sufficient distance to meet the processing of the slotted head of the screw thread end.

[0022] d. The fixed-distance tube 2 is sleeved onto the screw, and the screw with the fixed-distance tube 2 is screwed into the threaded hole of the flat tool 1, and the screw is tightened with an Allen wrench. After completion, other screws are screwed in one by one according to the above steps.

[0023] e. After completion, the flat tool 1 tooling with the screw is clamped to the vertical milling machine with a vise, and a 2mm thick saw blade is used to start processing the slotted head of the screw thread end.

[0024] The usage process of this device is roughly as follows:

[0025] 1. First, sleeve the fixed-distance tube 2 onto the lower Allen screw 3.

[0026] 2. Screw the screw with the fixed-distance tube 2 into the threaded hole of the flat tool 1 and tighten it.

[0027] 3. Screw the other screws into the flat tooling 1 one by one according to the above steps and pre-tighten them.

[0028] 4. Clamp the flat tooling 1 with screws into the vise.

[0029] 5. Use a 2-mm back saw blade to saw the one-word slots at the threaded ends of the screws in sequence.

[0030] 6. Use an Allen wrench to unscrew the processed screws, and repeat steps 1 to 5 to process the one-word slots of the remaining screws.
