DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The embodiment of the present application provides a bed workpiece positioning device, such as Figure 1 As shown, the device includes: a positioning mechanism 1, a fixing mechanism 2, and a scraping mechanism 3.

[0024] The positioning mechanism 1 includes a mounting plate 11 and a mounting frame 12 perpendicular to the mounting plate 11. A positioning rod 13 is perpendicularly mounted on the mounting frame 12. The positioning rod 13 is movable along the length of the mounting frame 12 and along its own axis. The fixing mechanism 2 is used to fix the mounting plate 11 to the mounting slot 5 on the workbench. The fixing mechanism 2 includes a locking block 21 arranged parallel to the bottom of the mounting plate 11 and facing the length of the workbench. The locking block 21 is perpendicularly provided with a pair of screws 22 passing through the mounting plate 11. The screws 22 are used to screw into nuts 23. The scraping mechanism 3 is provided at one end of the locking block 21 and is used to scrape off chips at the joint between the locking block 21 and the workbench. When used, the bed workpiece is generally a thick plate-like structure with plate frames for positioning on both side end faces. When positioning the bed workpiece, the bed workpiece is usually placed along the length of the workbench, and then multiple positioning devices are installed on the workbench mounting slots 5 on both sides of the bed workpiece to position the bed workpiece. The mounting groove 5 serves as the mounting base of the device, and the width of its groove is smaller than the width of the groove bottom. During installation, first align one end of the locking block 21 provided with the scraping mechanism 3 with the end of the mounting groove 5 to be installed, and push the locking block 21 into the mounting groove 5 along the length direction of the workbench. While pushing, the scraping mechanism 3 scrapes off the chips at the bottom end of the groove of the mounting groove 5; after pushing to the appropriate position, tighten the nut 23. Under the action of the nut 23, the locking block 21 gradually approaches the mounting plate 11 until the locking block 21 and the mounting plate 11 clamp the groove of the mounting groove 5, thereby completing the installation of the device; after the installation is completed, the positioning rod 13 is directed toward the corresponding plate frame, and at the same time, the positioning rod 13 is moved along the length direction of the mounting frame 12 to adjust its height, and then the positioning rod 13 is moved along its own axis so that it can abut against the side of the bed workpiece and be located on the bottom frame of the plate frame, thereby realizing the positioning of the bed workpiece. Through the structural design of the positioning rod 13 and the mounting frame 12, the adjustment of the positioning rod 13 is more flexible and can be applied to bed workpieces of various sizes, thereby improving the applicability of the device. At the same time, under the action of the scraping mechanism 3, the chips remaining at the bottom of the notch of the mounting groove 5 are scraped away, so that when the nut 23 is tightened, there are no chips between the locking block 21 and the bottom of the notch of the mounting groove 5, which not only improves the stability of the installation, but also improves the installation accuracy of the device, thereby ensuring the positioning accuracy of the device.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, the positioning rod 13 is coaxially inserted into a mounting seat 14, one end of the mounting seat 14 is sleeved on the mounting frame 12 and is movable along the length direction of the mounting frame 12, and a strip hole 131 is opened on the positioning rod 13 along the length direction of the mounting frame 12, and first matching holes 132 are opened on both sides of the strip hole 131 and are evenly arranged along the length direction of the positioning rod 13; a vertical plate 15 adapted to the strip hole 131 is vertically provided on the mounting plate 11, and one end of the vertical plate 15 is inserted into the strip hole 131, and second matching holes 151 are opened on the side of the vertical plate 15 and are evenly arranged along the length direction and matched with the first matching hole 132, and the first matching hole 132 and the second matching hole 151 are used to insert the locking pin 16. During use, the height of the positioning rod 13 can be adjusted by moving the mounting base 14 along the length of the mounting frame 12. The positioning rod 13 can be pulled out of the mounting base 14 to adjust its length. After the positioning rod 13 is fully mated with the panel frame, the latch 16 is inserted into the first mating hole 132 and the second mating hole 151 to secure the positioning rod 13. The latch 16, in conjunction with the first mating hole 132 and the second mating hole 151, not only secures the positioning rod 13 but also provides support for the positioning rod 13, thereby improving the reliability of the device.

[0026] Specifically, such as Figure 3 As shown, the scraping mechanism 3 includes a rotating seat 31 and a scraper 32 arranged on both sides of one end of the locking block 21. A rotating shaft 321 is formed at one end of the scraper 32. The rotating shaft 321 is engaged with the rotating seat 31. A torsion spring 322 is sleeved on the rotating shaft 321. When the locking block 21 is pushed into the placement groove 21, under the action of the torsion spring 322, the other end of the scraper 32 can always abut against the bottom of the slot 21, thereby improving the scraping effect of the scraping mechanism 3 and ensuring the installation accuracy of the device.

[0027] When installing the bed workpiece, it is also necessary to set a pad on the workbench and pad the bed workpiece above the workbench, which makes the installation process of the bed workpiece more complicated. Figure 1 and Figure 2 As shown, a supporting platform 4 can be connected to one end of the mounting plate 11, and the plane where the supporting platform 4 is located is arranged parallel to the mounting plate 11 and is spaced a predetermined distance from the mounting plate 11. One end of the supporting platform 4 is connected to a support plate 41 which is arranged coplanar with the mounting plate 11. With the cooperation of the supporting platform 4, the mounting plate 11 and the support plate 41, the bed workpiece can be supported parallel to the workbench, which not only optimizes the structure of the device, so that the device can not only position the bed workpiece, but also support it, but also simplifies the installation process of the bed workpiece and improves production efficiency.

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
