It has a simple structure and is easy to operate, and can realize rapid alignment of workpieces, with fast alignment and adjustment speed, saving time and effort.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model provides a alignment device, such as Figure 1-5 As shown, it includes an L-shaped positioning block 2 and a aligner 1 placed on the L-shaped positioning block 2. The L-shaped positioning block 2 can be placed on the machine tool workbench and located around the workpiece 4. The height of the L-shaped positioning block 2 matches the workpiece 4. Figure 6 As shown, the L-shaped positioning block 2 includes a first positioning surface 21 and a second positioning surface 22, the first positioning surface 21 is perpendicular to the second positioning surface 22, and the first positioning surface 21 is parallel to the horizontal plane. Figure 7-8As shown, the aligner 1 includes an aligning head 11 and an aligning seat 12. The aligning seat 12 is a rectangular parallelepiped. One end of the aligning head 11 is fixedly connected to the aligning seat 12. The end of the aligning head 11 away from the aligning seat 12 is a pointed head. The aligning head 11 has a horizontal surface coplanar with the top surface of the aligning seat 12. When the bottom surface of the aligning seat 12 fits with the first positioning surface 21 and the pointed head points to the workpiece 4, the aligner 1 is used to align the center line of the workpiece in the Z direction. When the top surface of the aligning seat 12 fits with the second positioning surface 22 and the pointed head points to the workpiece 4, the aligner 1 is used to align the center line of the workpiece in the X direction or Y direction. A plurality of L-shaped positioning blocks of a height matching the workpiece 4 are placed around the workpiece 4 on the machine tool worktable in advance. When the plurality of aligners 1 are placed on the L-shaped positioning block in a first placement posture, that is, the bottom surface of the alignment seat 12 is in contact with the first positioning surface 21 of the L-shaped positioning block, and the pointed tip is directed to the workpiece 4, the top surface of the aligner 1 is parallel to the first positioning surface 21 and the Z-direction line of the workpiece, and is used for Z-direction alignment of the workpiece. By adjusting the position of the workpiece 4 in the Z direction, the plurality of pointed tips are aligned with the Z-direction line of the workpiece, so as to realize the positioning of the workpiece 4 in the Z direction. When the plurality of aligners 1 are placed on the L-shaped positioning block in a second placement posture, even if the aligner 1 in the first placement posture is rotated 90°, the top surface of the alignment seat 12 is parallel to the first positioning surface 21 and the Z-direction line of the workpiece. The top surface is in contact with the second positioning surface 22. When the tip points to the workpiece 4, the top surface of the aligner 1 is parallel to the second positioning surface 22 and the marking line of the workpiece in the X direction or Y direction. It is used for aligning the workpiece in the X direction or Y direction. By adjusting the position of the workpiece 4 in the X direction or Y direction, multiple tips are aligned with the marking line of the workpiece in the X direction or Y direction, thereby achieving alignment of the workpiece in the X direction or Y direction. The L-shaped positioning block is fixed on the machine tool worktable. By only adjusting the placement posture of the aligner 1 on the L-shaped positioning block, the workpiece 4 can be quickly aligned in three directions. The structure is simple and the operation is convenient. When aligning different workpieces 4 on the machine tool, the problem of establishing a machine tool coordinate system each time is avoided, thereby improving work efficiency.

[0031] It is further preferred in the embodiment of the utility model that the alignment head 11 and the alignment seat 12 are integrally formed to facilitate manufacturing.

[0032] It is further preferred in the embodiments of the present invention that Fig.10 As shown, the cross section of the alignment seat 12 is an I-shaped cross section.

The I-shaped cross section is not only strong but also light. The two sides of the alignment seat 12 are hollow, which is convenient for the operator to grasp. Since the top surface of the alignment seat 12 fits with the second positioning surface 22 during alignment, and the bottom surface of the alignment seat 12 fits with the first positioning surface 21 during alignment, in order to avoid the small gravel on the second positioning surface 22 or the first positioning surface 21 affecting the degree of fit, the first groove 13 or the second groove 14 can accommodate small gravel to improve the accuracy of fit. Furthermore, the first groove 13 can extend to the top surface of the alignment head 11.

[0033] It is further preferred in the embodiments of the present invention that Figure 11-12 As shown, the alignment device further includes an inspection piece 3, which includes an inspection portion 32 and a storage portion 31. The aligner 1 can be fixedly connected to the storage portion 31, and the aligner 1 can detect the horizontal accuracy of the aligner 1 and the distance from the top surface to the bottom surface of the alignment seat 12 in the inspection portion 32. The aligner 1 is fixed to the storage portion 31, which is convenient for the storage and transportation of the aligner 1; before the aligner 1 is used, the aligner 1 needs to be placed in the inspection portion 32 to detect the height dimension from the top surface to the bottom surface of each aligner 1 and the horizontal accuracy of the top surface and the bottom surface of each aligner 1, so as to ensure the normal use of the aligner 1.

[0034] It is further preferred in the embodiment of the utility model that the inspection part 32 includes an inspection platform 321, an inspection boss 322 protruding from the inspection platform 321 and an inspection groove 323 opened on the inspection platform 321, the top surface of the inspection boss 322 is parallel to the top surface of the inspection platform 321, and the distance from the top surface of the inspection boss 322 to the top surface of the inspection platform 321 is equal to the distance from the top surface to the bottom surface of the alignment seat 12, the length direction of the inspection groove 323 is parallel to the width direction of the inspection platform 321, and the width of the inspection groove 323 is smaller than the distance from the tip to the alignment seat 12.
