Description

Technical Field

[0001] The utility model relates to a straight - line burr removal tool, belonging to the technical field of connector workpiece processing, and is applicable to removing burrs and redundant materials with straight - line structures on a bench drill. Background Technique

[0002] In the field of CNC precision gang - tool lathe processing, for workpieces that cannot be directly processed with straight lines, the straight lines of the workpiece are usually processed separately first, and then the workpiece is turned. During the turning process, the burrs at both ends of the straight line turn into the middle of the workpiece, forming hard - edge burrs, redundant materials, etc. on the end face of the workpiece. The traditional method for removing straight - line burrs is to hold a triangular scraper by hand and remove the burrs one by one at the location with straight - line burrs. Manual operation is not only time - consuming and labor - intensive, with a large labor fatigue intensity, low production efficiency, and poor consistency of the processed workpieces. The processing efficiency and qualification rate of the workpieces are low. Content of the Utility Model

[0003] The purpose of the utility model is to provide a straight - line burr removal tool. Starting from a mechanical device, it overcomes the bottleneck problem of traditional manual straight - line burr removal. The workpiece is placed in a flower die. On the premise that the spindle of the drill press does not rotate, the hand - held rotating handle is pressed down, so that the teeth of the flower die slide along the surface of the straight line, achieving the effect of removing straight - line burrs and surface redundant materials.

[0004] The purpose of the utility model is realized by adopting the following technical solutions:[[]]

[0005] A straight - line burr removal tool is composed of two parts: a punch and a flower die; a punch end - cover is installed at the bottom of the punch; the flower die itself has a taper with an angle of 6°; the material of the punch end - cover is a circular polyether ether ketone rod; the material of the punch is stainless steel.

[0006] The beneficial effects of adopting the above - mentioned technical solutions are:[[]]

[0007] Compared with the prior art, the fixture provided by the utility model is simple to assemble, can remove all straight - line burrs of one workpiece at a time, and avoids the problem that the traditional hand - held triangular scraper removes burrs one by one at the location with straight - line burrs. Manual operation is not only time - consuming and labor - intensive, but also has a large labor fatigue intensity. To a great extent, it improves the processing efficiency of the workpiece and the qualification rate of the workpiece. Description of the Drawings

[0014] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] A straight-line burr removal tool is composed of two parts: a punch 1 and a die 3; a punch end cover 2 is installed at the bottom of the punch 1. When the punch 1 contacts the workpiece, the punch end cover 2 plays a buffering role to avoid hard contact between the punch 1 and the end face of the workpiece 4, thereby preventing the occurrence of bruising phenomena, and ultimately ensuring the quality of the workpiece end face. The punch 1 mainly enables the workpiece 4 to pass through the die 3 smoothly, so as to achieve the effect of removing the redundant substances in the straight lines of the workpiece; the die 3 itself has a taper of 6°, which plays a role in guiding the workpiece when the workpiece 4 is placed in the die 3 to ensure that the workpiece can be placed normally.

[0016] Material selection: Since the punch 1 needs to be in direct contact with the workpiece 4, a plastic punch end cover 2 needs to be added to the end face of the punch 1 to avoid hard contact between the workpieces 4 and prevent bruising of the end face of the workpiece 4. Therefore, the material of the punch end cover 2 can be selected as a round polyether ether ketone rod (PEEK), and the punch 1 can be made of stainless steel material with relatively high hardness.

[0017] Structural design: The die 3 is used for placing the straight-line workpiece 4; a bench drill is used to press down the workpiece punch to ensure that the workpiece 4 can pass through the die 3 smoothly and effectively remove the straight-line burrs; the punch end cover 2 is used to contact the components to avoid bruising caused by hard contact.

[0018] A method for using a straight-line burr removal tool includes the following steps:

[0019] a) According to the workpiece to be processed, select a die with the same straight-line specification. After adjusting the center of the die, fix it to the workbench of the bench drill;

[0020] b) Place the workpiece in the die fixture, manually press the handle of the bench press, and use the features of the die (inner ring teeth) to remove the burrs and surface redundant substances on the straight lines of the workpiece.

[0021] Embodiment:

[0022] Before processing the knurling, the outer diameter is φ4mm, the module of the straight knurl is m0.2, and the pitch of the straight knurl is P = 0.628. Place the workpiece in the knurling die fixture that has been adjusted and qualified. After locking the spindle of the bench drill, rotate the handle of the bench drill to make the workpiece pass through the knurling die fixture, so that the workpiece is subjected to secondary precision drawing to remove the excess material and hard-edge burrs on the straight knurl of the workpiece, etc.

Claims
