[0034] During mechanical processing, the workpiece generally needs to be placed on a positioning device. However, the existing positioning devices have low accuracy in position adjustment and cannot meet the requirements of high-precision parts processing.

[0035] For this reason, Figure 1 and Figure 2As shown, the high-precision positioning device proposed by the utility model includes a base 100, a first sliding adjustment assembly 200, a second sliding adjustment assembly 300 and a positioning block 500 connected in sequence, wherein the first sliding adjustment assembly 200 is connected to the second sliding adjustment assembly 300, and the first sliding adjustment assembly 200 and the second sliding adjustment assembly 300 are both used to adjust the horizontal position of the positioning block 500. Specifically, the first sliding adjustment assembly 200 includes a first micrometer 210, a first mounting block 230, a first adjustment block 220 and a first fixing screw, wherein the first adjustment block 220 and the first mounting block 230 are both slidably connected to the base 100 along the first horizontal direction, the first micrometer 210 is mounted on the base 100, and the driving shaft of the first micrometer 210 abuts against the groove wall of the first adjustment block 220, and is used to drive the first adjustment block 220 to move along the first horizontal direction. After the first micrometer 210 is adjusted, the first fixing screw connects and drives the first mounting block 230 and the first adjustment block 220 to move in opposite directions, and drives the first mounting block 230 to be pressed and fixed against the base 100. Similarly, the second sliding adjustment assembly 300 includes a second micrometer 310, a second mounting block 330, a second adjustment block 320, and a second fixing screw, wherein the second adjustment block 320 and the second mounting block 330 are both slidably connected with the first adjustment block 220 along the second horizontal direction, the second micrometer 310 is mounted on the first adjustment block 220, and the driving shaft of the second micrometer 310 abuts against the groove wall of the second adjustment block 320, and is used to drive the second adjustment block 320 to move in the second horizontal direction. After the second micrometer 310 is adjusted, the second fixing screw connects and drives the second mounting block 330 and the second adjustment block 320 to move in opposite directions, and drives the second mounting block 330 to be pressed and fixed against the first adjustment block 220. Furthermore, the positioning block 500 is installed on the second adjustment block 320, and the positioning block 500 is used to position the workpiece 600. For example, the workpiece 600 is a tee joint of a faucet, and the positioning block 500 is provided with a positioning groove for positioning the tee joint of the faucet. It should be noted that the first micrometer 210 can adjust the first horizontal position of the first adjustment block 220 with high precision, and the second micrometer 310 can adjust the second horizontal position of the second adjustment block 320 with high precision, thereby adjusting the horizontal position of the workpiece 600 located on the positioning block 500 with high precision to meet the high-precision processing requirements of the workpiece 600.

[0036] In some embodiments, the first horizontal direction and the second horizontal direction are arranged obliquely (not shown in the figure), and the first horizontal direction and the second horizontal direction can form a horizontal coordinate system to meet the adjustment of the entire horizontal position of the workpiece 600. Figure 1 As shown, the first horizontal direction is perpendicular to the second horizontal direction, the arrangement is reasonable, and the structure is simple.

Since the dovetail groove has an inclined surface for cooperation, the first mounting block 230 and the first adjustment block 220 both have a small amount of adjustment travel, so that when the first fixing screw drives the first mounting block 230 and the first adjustment block 220 to move in opposite directions, the first mounting block 230 can be better pressed and fixed against the groove wall of the dovetail groove. Specifically, the first mounting block 230 is provided with a first screw 420 clearance hole 231, the first adjusting block 220 is provided with a first threaded hole 2203 matching the first screw 420 clearance hole 231, the first fixing screw is passed through the first screw 420 clearance hole 231 and is threadedly connected to the first threaded hole 2203, so as to drive the first mounting block 230 and the first adjusting block 220 to move in opposite directions. Similarly, the first adjusting block 220 is provided with a third dovetail groove 2201 and a fourth dovetail groove 2202, the third dovetail groove 2201 and the fourth dovetail groove 2202 are symmetrically arranged, the second mounting block 330 partially extends into the third dovetail groove 2201 and slides with the third dovetail groove 2201, and the second adjusting block 320 partially extends into the fourth dovetail groove 2202 and slides with the fourth dovetail groove 2202. Similarly, since the dovetail groove has an inclined surface for matching, the second mounting block 330 and the second adjustment block 320 both have a small amount of adjustment travel, so that when the second fixing screw drives the second mounting block 330 and the second adjustment block 320 to move in opposite directions, the second mounting block 330 can be well pressed and fixed against the groove wall of the dovetail groove. Specifically, the second mounting block 330 is provided with a second screw clearance hole 331, and the second adjustment block 320 is provided with a second threaded hole 3201 matching the second screw clearance hole 331.

[0037] In some embodiments of the present invention, in addition to using the driving shaft of the first micrometer 210 to push the first adjustment block 220 outward, such as Figure 1 and Figure 2As shown, the base 100 is installed with a first pulling assembly 400, and the first pulling assembly 400 is connected to and drives the first adjustment block 220 to move along the first horizontal direction, and can pull the first adjustment block 220 back. Specifically, the first pulling assembly 400 includes a first fixing seat 410 and a first screw 420, and the first fixing seat 410 is relatively fixed to the base 100.

In some embodiments, the first adjustment block 220 is installed with a second pulling assembly, and the second pulling assembly is connected to and drives the second adjustment block 320 to move along a second horizontal direction (not shown in the figure). It is easy to understand that the connection structure between the second pulling assembly and the second adjustment block 320 can refer to the connection structure between the first pulling assembly 400 and the first adjustment block 220, and will not be described in detail here.

[0038] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a guide structure is provided between the positioning block 500 and the second adjustment block 320 and fixed by a third fixing screw, the connection precision is high, and the positioning block 500 can be easily replaced according to different workpieces 600.
