[0002] During machining, after workpieces (such as metal parts, injection molded parts, etc.) are cut, stamped or laser cut, burrs are easily generated on the edges. It is necessary to position the workpiece and then repair it with a burr removal tool. When the tool is close to the workpiece for processing, it is necessary to use a positioning pressure head to squeeze and position the product to ensure stability during the repair process.

[0003] In existing deburring machines, the positioning pressure head and the deburring tool are mounted together on the lifting mechanism during the workpiece repair process. The pressure head has a telescopic function, and its position is slightly lower than the tool. It can first squeeze the workpiece for positioning to ensure the stability of the workpiece before cleaning. During the pressing process, the pressure head and the workpiece are rigidly squeezed. Combined with the vibration generated during the repair process, this may cause wear on the surface of the workpiece, affecting the workpiece processing quality. This needs to be optimized and improved. Utility Model Content

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a positioning pressure head for a deburring machine, including: a support frame 1, a lifting frame 2 is provided at the front end of the support frame 1, a mounting base 3 is connected to the front end of the lifting frame 2, and a deburring knife 4 is connected to the bottom end of the mounting base 3.

[0025] The front end of the mounting base 3 is provided with a compression replacement component, which includes a cylinder 6, and the bottom end of the cylinder 6 is provided with a connecting seat 9. The inner side of the connecting seat 9 is provided with a snap-fit ​​seat 12, and the bottom end of the snap-fit ​​seat 12 is provided with a buffer pad 15. The compression replacement component is used for contact protection of the workpiece.

[0026] Specifically, such as Figure 4 As shown, cylinder 6 is connected to the inner side of mounting bracket 18, and the inner side of cylinder 6 is connected to air control pipe 7, which is connected to an external air pump to facilitate control of the extension and retraction of cylinder 6.

[0027] Specifically, such as Figure 2 As shown, the bottom end of the cylinder 6 is connected to a connector 8, and a connector 9 is connected to the bottom end of the connector 8. The fixed connection between the connector 8 and the connector 9 facilitates the extension and retraction adjustment of the connector 9.

[0028] Specifically, such as Figure 3As shown, the inner side of the connector 9 is provided with a snap-fit ​​groove 10, and the inner side of the snap-fit ​​groove 10 is provided with a positioning hole 11. After the snap-fit ​​seat 12 is inserted into the top of the snap-fit ​​groove 10, it is rotated 90 degrees and then snapped into the bottom of the snap-fit ​​groove 10, so that the snap-fit ​​pin on the inner side of the snap-fit ​​seat 12 is locked in the positioning hole 11 for limitation.

[0029] Specifically, such as Figure 3 As shown, the top of the snap-fit ​​seat 12 is connected to a rotating shaft 13. The rotating shaft 13 is set to fit against the elastic compression plate 14 inside the connector seat 9, so that the smooth rotation of the snap-fit ​​seat 12 is not affected after contact.

[0030] Specifically, such as Figure 3 As shown, an elastic compression plate 14 is connected to the inner bottom end of the connecting seat 9. The elastic compression plate 14 presses downward, causing the snap-fit ​​seat 12 to snap into the inner bottom end of the snap-fit ​​groove 10.

[0031] The mounting base 3 is provided with a mounting adjustment component on its outer side. The mounting adjustment component includes a connecting block 5, and a rotating positioning plate 17 is provided at the front end of the connecting block 5. A mounting bracket 18 is provided on the outer side of the rotating positioning plate 17. The mounting adjustment component is used to adjust the positioning position.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, the connecting block 5 is located on the outside of the mounting base 3, and the front end of the connecting block 5 is connected to the sliding limit plate 16. The rotating positioning plate 17 is connected to the front end of the sliding limit plate 16. The rotating positioning plate 17 can be rotated and adjusted at the front end of the sliding limit plate 16 so that the hole on the rotating positioning plate 17 corresponds to the fixing hole 20.

[0033] Specifically, such as Figure 4 As shown, the inner side of the mounting bracket 18 is provided with an adjustment groove 19, and the upper and lower sides of the adjustment groove 19 are provided with fixing holes 20. The sliding limit plate 16 can be slidably adjusted inside the adjustment groove 19, so that the rotating positioning plate 17 can be installed on the fixing holes 20 at different positions.

[0034] In this embodiment: the workpiece is pre-positioned by setting a removable snap-fit ​​seat 12, which improves the stability of the workpiece when repairing burrs. A buffer pad 15 is set to reduce the friction between the snap-fit ​​seat 12 and the workpiece, thereby reducing wear on the workpiece. The buffer pad 15 can also be removed by the snap-fit ​​method between the snap-fit ​​seat 12 and the connecting seat 9, which improves the protection of the pressure head for workpiece processing positioning. In order to facilitate the positioning adjustment between different workpieces, the installation and adjustment of different positions can be carried out by sliding between the sliding limit plate 16 and the mounting bracket 18, so that the position of the snap-fit ​​seat 12 used to press the workpiece can also be adjusted accordingly.

[0035] Specifically, this solution involves repairing burrs on a workpiece by controlling the position of the trimming knife 4 via the mounting base 3. Before processing the workpiece, pre-positioning adjustment is required. The cylinder 6 drives the connector 8 and connector 9 to rise and fall, thereby causing the bottom locking seat 12 to contact the workpiece for compression and positioning. The contact point between the locking seat 12 and the workpiece is protected by a buffer pad 15 to reduce wear on the workpiece surface. The buffer pad 15 can be replaced if used for an extended period. At this point, the positioning hole 11 is pressed upwards, and the elastic pressing plate 14 is compressed, causing the inner locking post of the locking seat 12 to disengage from the positioning. By rotating the locking seat 12 90 degrees through hole 11, the locking seat 12 can be moved downwards to connect the buffer pad 15. Conversely, the locking seat 12 can be moved downwards to perform the locking installation. When positioning different workpieces, the pressing position of the locking seat 12 may need to be adjusted. At this time, the screws inside the rotating positioning plate 17 can be removed, and then the sliding limit plate 16 can be slid in the adjusting groove 19 inside the mounting bracket 18 to adjust its position. After reaching the appropriate position, the mounting hole on the rotating positioning plate 17 can be aligned with the fixing hole 20 for adjustment and installation. This facilitates stable positioning of different workpieces when repairing burrs, ensuring the repair effect.

[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
