[0035] The utility model embodiment provides a kind of polishing positioning tool, can effectively position workpiece, prevent workpiece deformation, facilitate polishing operation.

[0036] The technical scheme provided by the utility model is described in more detail below. Figure 1-Figure 5 The technical scheme provided by the utility model is described in more detail below.

[0037] As shown in Figure 1-Figure 5 The utility model provides a kind of polishing positioning tool, including rack 1, sliding seat 2, adjusting block 3 and grinding head 4, wherein: rack 1 has workbench, sliding seat 2 is fixed on workbench, sliding seat 2 has sliding slot 21, the bottom wall of sliding slot 21 is compared with the inclined setting of the table top of workbench;Adjusting block 3 is located in sliding slot 21, adjusting block 3 can be moved along sliding slot 21 under the external force push, to be positioned at different heights in sliding slot 21;As shown in Figure 5 Adjusting block 3 is provided with slot 31, slot 31 is used to insert at least part of workpiece 100 therein, to position workpiece 100;Grinding head 4 is fixed on rack 1, for polishing the surface of workpiece 100.

[0038] The slide 2 can be fixed to the workbench of the frame 1 by means of a locking member 8 such as a screw. The adjusting block 3 is clamped in the chute 21 by the side wall of the chute 21 and requires a certain external force to push or pull it to move in the chute 21. Since the bottom wall of the chute 21 is an inclined plane, when the adjusting block 3 is pulled or pushed, the vertical height of the adjusting block 3 changes, thereby adjusting the thickness of the workpiece 100 to be ground off.

[0039] In the grinding and positioning tool of this embodiment, the adjusting block 3 moves along the slide groove 21 under the push of external force, so as to be positioned at different heights in the slide groove 21. When a part of the workpiece 100 is inserted into the slot 31, it can be positioned in the slot 31, which is convenient for the grinding head 4 to grind the positioned workpiece 100, and the way in which the slot 31 positions the workpiece 100 can prevent the workpiece 100 from deforming; by positioning the adjusting block 3 at different heights of the slide groove 21, the thickness of the workpiece 100 ground off can be adjusted, which is convenient to use.

[0040] As an alternative embodiment, see Figure 2 As shown, the bottom surface of the adjustment block 3 is an inclined surface 33, which fits the bottom wall of the chute 21 and can move along the bottom wall of the chute 21 under the action of external force.

[0041] The inclined surface 33 of the adjusting block 3 fits with the bottom wall of the slide groove 21. When the adjusting block 3 is pulled or pushed, the inclined surface 33 moves along the bottom wall of the slide groove 21, and the vertical height of the adjusting block 3 changes, thereby adjusting the grinding thickness of the workpiece 100.

[0042] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the grinding and positioning tool also includes a positioning screw 11, wherein: Figure 2 As shown, the upper end of the slide 21 is provided with a closed side 211 , and the closed side 211 is provided with a threaded hole. The positioning screw 11 passes through the threaded hole to abut against the end of the adjustment block 3 to position the adjustment block 3 in the slide 21 .

[0043] Since the positioning screw 11 is threadedly connected to the closed side 211 of the chute 21, the length of the positioning screw 11 extending into the chute 21 can be adjusted by twisting the positioning screw 11. When the adjustment block 3 abuts against the end of the positioning screw 11, as shown in FIG. Figure 2 As shown, the adjustment block 3 can be positioned within the chute 21 to determine the target grinding thickness of the workpiece 100. When different degrees of grinding are required on the workpiece 100, that is, when the grinding thickness of the workpiece 100 is different, the adjustment block 3 can be positioned at different positions within the chute 21 in the above manner to adjust the grinding thickness of the workpiece 100. During the grinding process, the end of the adjustment block 3 always abuts against the positioning screw 11, thereby positioning the workpiece 100.

[0044] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the chute 21 extends along the length direction of the adjustment block 3, and an opening 212 is provided at the lower end of the chute 21. The adjustment block 3 can be slid out or assembled from the opening 212, which is convenient for maintenance of the adjustment block 3.

[0045] As an alternative embodiment, see Figure 5 As shown, a handle 32 is fixed to the lower end of the adjusting block 3. The handle 32 is a U-shaped structure for hand-holding.

[0046] The user can hold the handle 32 to pull or push the adjusting block 3, thereby changing the position of the adjusting block 3 in the sliding groove 21, which is convenient to use.

[0047] As an alternative embodiment, see Figure 5 As shown, the grinding and positioning tooling also includes a lever 9, which is rotatably connected to the adjustment block 3. The lever 9 includes a prying end 92 and a pressing end 91, wherein: at least the prying end 92 is located in the slot 31. When the workpiece 100 is inserted into the slot 31, the prying end 92 rests against the bottom of the workpiece 100. By pressing the pressing end 91 downward, the lever 9 can rotate and lift the prying end 92, thereby pushing the workpiece 100 out of the slot 31.

[0048] For details, see Figure 5 As shown, the lever 9 is rotatably connected to the opposite side walls of the slide groove 21 through the pin 10. When the pressing end 91 is pressed downward, the lever 9 rotates around the pin 10 as the axis, and the prying end 92 is tilted, thereby pushing the workpiece 100 out of the slot 31, making it easier to remove the workpiece 100.

[0049] As an optional embodiment, a pressing plate 93 is fixed to the pressing end 91 to increase the hand action area and facilitate the pressing operation.

[0050] As an alternative embodiment, see Figure 1-Figure 3 As shown, the grinding and positioning tooling also includes a main support frame 5, a fixed seat 6 and an adjustment rod 7, wherein: the main support frame 5 is fixed to the frame 1, the fixed seat 6 is fixed to the main support frame 5, and the fixed seat 6 is provided with a receiving cavity running through its upper and lower ends. The grinding head 4 includes a fixedly connected base 41 and a polishing disc 42, the base 41 is placed in the receiving cavity, and the polishing disc 42 is used to grind the surface of the workpiece 100; the adjustment rod 7 is rotatably connected to the fixed seat 6, and the adjustment rod 7 is transmission-connected to the grinding head 4 for adjusting the vertical height of the grinding head 4. Figure 3 As shown, a gear portion 71 is fixed on the adjusting rod 7, and the gear portion 71 is located in the accommodating cavity. A rack 411 is provided on the base 41, and the rack 411 is vertically arranged. The gear portion 71 is engaged with the rack 411, and the vertical height of the grinding head 4 can be adjusted by rotating the adjusting rod 7.

[0051] When the adjusting rod 7 is manually rotated, the gear on the adjusting rod 7 engages with the rack 411 on the grinding head 4, and the grinding head 4 moves in the vertical direction, thereby adjusting the vertical position of the polishing disk 42 so that the polishing disk 42 contacts the surface to be polished of the workpiece 100.

[0052] As an alternative embodiment, see Figure 5 As shown, the grinding positioning tool also includes a locking piece 8, a threaded hole is opened on the side wall of the fixing seat 6, and the locking piece 8 is threadedly connected to the fixing seat 6 through the threaded hole; a guide groove 412 is provided on the base 41, and the guide groove 412 is vertically arranged. The end of the locking piece 8 extends into the guide groove 412, and rotating the locking piece 8 can lock the grinding head 4.

[0053] The locking member 8 can be a locking bolt. By turning the locking member 8, the length of the locking member 8 extending into the guide groove 412 can be adjusted. When the locking member 8 and the guide groove 412 are not in contact, the adjusting rod 7 is rotated to allow the grinding head 4 to move vertically. The guide groove 412 cooperates with the locking member 8 to provide vertical guidance. When the locking member 8 and the guide groove 412 are in contact with each other, the locking member 8 can lock the grinding head 4.
