Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a cutting auxiliary calibration device for processing plunger blanks. Background Technology

[0002] A plunger blank is the raw material of a plunger that has not undergone any processing. Cutting a plunger blank requires a cutting device.

[0003] Currently, some cutting devices on the market, such as the utility model patent with authorization announcement number CN221018874U, disclose a cutting device for processing stainless steel round bars. This device, through the setting of the drive component, first inserts one end of the bar into the interior of the telescopic barrel, then slides the extrusion cylinder on the outside of the telescopic barrel, and the extrusion cylinder simultaneously extrudes the circumference of the moving block. The moving block contacts and extrudes the outside of the bar, and then the extrusion head moves to clamp the end face of the bar. Finally, the bar is cut by the cutting machine. However, during use, this device only supports and clamps the two ends of the workpiece. When the cutting position is far from the clamping position, the workpiece is prone to large-scale vibration during the cutting process due to the lack of support and clamping at the cutting position. This leads to reduced cutting accuracy and uneven cutting edges, which not only affects the cutting quality but may also shorten the service life of the cutting blade equipment.

[0004] Therefore, we propose a cutting auxiliary calibration device for processing plunger blanks to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problem that some current cutting devices only support and clamp the two ends of the workpiece during use. When the cutting position is far from the clamping position, the workpiece is prone to large-scale vibration during the cutting process due to the lack of support and clamping at the cutting position. This leads to reduced cutting accuracy and uneven cutting edges, which not only affects the cutting quality but may also shorten the service life of the cutting blade equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cutting auxiliary calibration device for processing plunger blanks, comprising: a device box, wherein limit frames are symmetrically arranged on the device box, and a limit rod is arranged between the two limit frames;

[0007] An auxiliary mechanism is provided on the limiting rod. The auxiliary mechanism includes two mechanism frames, and a connecting plate is connected between the two mechanism frames. A limiting hole is provided on the mechanism frame to slide and connect with the limiting rod.

[0008] A clamping mechanism is provided on the mechanism frame, and the clamping mechanism includes a first triangular clamping plate and a second triangular clamping plate;

[0009] A control mechanism is provided on the limit frame and the mechanism frame, and the first triangular clamp and the second triangular clamp move under the action of the control mechanism;

[0010] A fixing mechanism is provided on the limiting frame, and the auxiliary mechanism is fixed to the limiting rod by the fixing mechanism.

[0011] Furthermore, a cutting machine is movably mounted on the back of the device box.

[0012] Furthermore, the control mechanism includes two screws, each with a sprocket at its top end, and a transmission chain between the two sprockets. One of the screws has a rotating rod at its top end. The screws are symmetrically provided with a first external thread and a second external thread, which are opposite in direction. The first triangular clamp has a first threaded hole that is threadedly connected to the second external thread, and the second triangular clamp has a second threaded hole that is threadedly connected to the first external thread. The second triangular clamp also has a first through-plate groove that is slidably connected to the first triangular clamp.

[0013] Furthermore, the mechanism frame is symmetrically provided with spring compression chambers, and a rotating chamber is provided between the two spring compression chambers. A wire hole is provided between the spring compression chamber and the rotating chamber. The fixing mechanism includes a rotating column, a baffle, and a compression spring. The rotating column is rotatably connected in the rotating chamber, and a rotating plate is connected to one end of the rotating column. The baffle and the compression spring are arranged in the spring compression chamber. A locking post is connected to one side of the baffle, and a pull line is connected between the other side of the baffle and the rotating column. A knob is connected to the other end of the rotating column. Multiple evenly distributed locking holes are provided on the limiting rod, and the locking holes are adapted to the locking posts.

[0014] Furthermore, the limiting frame is provided with a limiting mechanism, which includes a first triangular limiting plate and a second triangular limiting plate. The first triangular limiting plate has a third threaded hole that is threadedly connected to the second external thread, and the second triangular limiting plate has a fourth threaded hole that is threadedly connected to the first external thread. The second triangular limiting plate also has a second through-plate groove that is slidably connected to the first triangular limiting plate. Both the first and second triangular limiting plates are provided with ball bearings.
