Technical Field

[0001] The utility model belongs to the technical field of bar processing, and particularly relates to a puller for bar processing and equipment using the puller. Background Art

[0002] When using bar material for processing, it is usually necessary to perform rough processing on the bar material. Using a three-jaw chuck to clamp the bar material is slow and inefficient, and is not suitable for batch rough processing of bar material.

[0003] Prior art, such as the one disclosed in Chinese Patent Publication No. CN 205342593 U, discloses a non-perfectly round bar turning fixture. This fixture maintains stable contact between the outer protrusions of the bar clamp and the fixture sleeve, while the inner protrusions maintain contact with the bar, making it particularly suitable for clamping non-perfectly round bars. However, this prior art is primarily suitable for clamping non-perfectly round bars, making it difficult to clamp round bars and incapable of automated rough machining of bars. Utility Model Content

[0011] Preferably, the chamfer angle ranges from 10° to 30°.

[0012] Preferably, the separation grooves are provided in a plurality and are evenly distributed along the circumference of the clamping portion. After the separation grooves are provided, when the bar is inserted into the clamping hole, due to the interference fit between the bar and the clamping hole, the clamping portion slightly expands and deforms outwards to clamp the bar.

[0013] Also provided is a bar processing device using the above-mentioned puller, comprising a main body, a first guide rail, a spindle box, a chuck, a tailstock, a tool holder, a second guide rail, and a robotic arm, wherein the guide rail is fixedly mounted on the main body, the spindle box is mounted at one end of the guide rail, the tailstock is mounted on the guide rail opposite the spindle box, the chuck is mounted on the spindle box, the tool holder is mounted on the main body via the second guide rail, a turning tool is provided on the tool holder, the robotic arm is disposed at the top of the main body, and the puller is fixed in the chuck.

[0017] 2. Existing clamping fixtures are suitable for turning non-perfectly round bars, and their clamping force for round bars is limited. The present invention utilizes a cylindrical clamping portion with clamping grooves evenly distributed along its circumference. With the separation grooves, when the bar is inserted into the clamping hole, the clamping portion slightly expands and deforms due to the interference fit between the bar and the clamping hole, clamping the bar. This eliminates the need for adjusting the chuck or other structures, resulting in fast clamping speed and high processing efficiency.

[0018] 3. In the present invention, a chamfer is provided at one end of the clamping hole away from the fixing portion, and the chamfer serves as a transition to facilitate the insertion of the rod.

[0019] 4. In the bar processing equipment of the present invention, the bar can be inserted into and pulled out of the positioning hole due to the setting of the puller. There is no need to adjust the chuck, and the position of the positioning hole remains unchanged. The robotic arm can accurately insert the bar into the positioning hole of the puller, which is convenient for automatic rough processing of the bar. BRIEF DESCRIPTION OF THE DRAWINGS
