Description

Technical Field

[0001] This utility model relates to the field of automobile wheel hub manufacturing, and in particular to a laser scanning and engraving device for automobile wheel hubs. Background Technology

[0002] After the car wheel rims are finished, an additional process is laser engraving or barcode scanning. Depending on the customer's needs, laser engraving or identification codes are applied to different locations on the wheel rim. This engraving operation is performed by an engraving machine. The process involves placing the car wheel rim on the engraving machine's worktable, measuring the laser distance, determining the position, and then starting the engraving.

[0003] In existing technologies, the worktable of engraving machines lacks fixtures for positioning automotive wheel hub products, resulting in the need for re-measurement and positioning for each engraving, leading to low efficiency and cumbersome operation. Furthermore, some products have engraving positions that are not on a horizontal plane. Due to the limitations of the engraving machine's mechanical hardware, engraving on such non-horizontal surfaces yields even worse results compared to engraving on a horizontal plane.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] One embodiment of this application, such as Figures 1 to 4 As shown, a laser marking and engraving device for automobile wheel hubs 50 includes: a laser marking machine, a tooling fixture 20, and a frame 11; the laser marking machine includes: a processing spindle 12, an X-axis slide rail 13, a Z-axis slide rail 14, a vertical sliding plate 15, a horizontal sliding plate 16, and a drive device; the horizontal sliding plate 16 is slidably disposed on the bottom of the X-axis slide rail 13; the Z-axis slide rail 14 is vertically connected to the bottom of the horizontal sliding plate 16; the processing spindle 12 is mounted on the bottom of the vertical sliding plate 15; one side of the vertical sliding plate 15 is slidably mounted on the Z-axis slide rail 14; such that the processing spindle 12 can move along the X-axis slide rail 13 or the Z-axis slide rail 14 under the drive of the drive device.

[0023] The top surface of the frame 11 is provided with a working plane; the tooling fixture 20 includes: a base 21, an adjusting block 22, clamping bolts, and an adjusting mechanism; a rotating shaft 24 is horizontally provided on the left side of the base 21, and the inner and outer ends of the rotating shaft 24 are respectively rotatably installed in the rotating shaft holes 25 provided on the inner and right sides of the base 21; a hinge hole is provided on the left side of the adjusting block 22, and the hinge hole is sleeved on the outside of the rotating shaft 24, so that the left side of the adjusting block 22 is rotatably hinged to the left side of the base 21; the top surface of the adjusting block 22 is provided with a clamping surface, and the clamping surface is provided with a clamping screw hole, the position of which is aligned with the position of the clamped automobile wheel hub 50. The pre-set screw hole at the center of the rim corresponds to the clamping bolt passing through the clamping screw hole and the pre-set screw hole in sequence, so that the clamping surface is fitted to the center position of the back of the rim of the clamped car wheel hub 50; the adjustment mechanism is supported between the right side of the adjustment block 22 and the right side of the base 21. The adjustment mechanism can adjust its own structure according to the processing needs, so that the right side of the adjustment block 22 can be rotated to a designated position relative to the right side of the base 21 around the rotating shaft 24; the laser engraving machine and the tooling fixture 20 are installed on the working plane, so that the tooling fixture 20 is located directly below the processing spindle 12 of the laser engraving machine.

[0024] Preferably, the tooling fixture 20 further includes a support block 26, the bottom surface of which is fitted against the top surface of the adjusting block 22, and a locking bolt 23 passes through the middle of the support block 26 and the adjusting block 22, so that the support block 26 and the adjusting block 22 are connected into a detachable integrated structure. Because different car wheel hubs 50 have different structures, especially the rim shape, and the laser scanning and engraving device requires a structure that is close to the back of the rim to position the car wheel hub 50, in actual operation, it is necessary to manufacture support blocks 26 with different clamping surface structures according to the different structures of the car wheel hubs 50 to be clamped. In subsequent processing, the locking bolt 23 can be loosened and the support block 26 replaced to achieve quick clamping of different car wheel hubs 50.

[0025] Preferably, the top surface of the adjusting block 22 is recessed downwards and has a positioning hole 27; the bottom surface of the support block 26 has a positioning post 28; the positioning hole 27 and the positioning post 28 have the same cross-section, both being regular polygons. This allows the car wheel hub 50 to be rotated and adjusted around the locking bolt 23 after it is fitted and installed with the support block 26, by rotating the positioning post 28 and the positioning hole 27, making the clamping of the car wheel hub 50 more flexible and convenient.

[0026] Specifically, the cross-sections of the positioning hole 27 and the positioning post 28 are regular hexagons, regular octagons, or regular dodecagons.

[0027] Preferably, the adjustment mechanism includes: a pin strip 31 and a pin rod 34; the pin strip 31 has a plurality of pin holes 32 evenly distributed along its extension direction; the base 21 has a through hole 33 on its right side; the upper end of the pin strip 31 is rotatably hinged to the right side of the adjustment block 22; any pin hole 32 on the pin strip 31 is directly opposite the through hole 33, and when the pin rod 34 is inserted into the pin hole 32 and the through hole 33, the position between the adjustment block 22 and the base 21 is fixed. When the adjustment mechanism adopts the above-mentioned adjustable pin structure, the corresponding pin hole 32 and through hole 33 can be selected according to the plane position where the lettering needs to be engraved on the car wheel hub 50, and then the car wheel hub 50 can be flipped and positioned for clamping. The advantages of this adjustable pin structure are simple structure, convenient adjustment operation, and larger adjustable range. However, the disadvantage is that the car wheel hub 50 needs to be removed during adjustment to save effort, and the adjustable positioning angle is a fixed number of values, not linear.

[0028] Preferably, the pin bar 31 has seven pin holes 32. When the uppermost pin hole 32 of the pin bar 31 is aligned with the through hole 33, the adjusting block 22 is in a horizontal position. When the lowermost pin hole 32 of the pin bar 31 is aligned with the through hole 33, the adjusting block 22 is rotated 90 degrees relative to the base 21. This allows the seven pin holes 32 to adjust the rotation range of the adjusting block 22 from 0 to 90 degrees, with an adjustment angle of 15 degrees between any two adjacent through holes 33. This parameter setting ensures that in most scenarios where lettering is required on the surface of the car wheel hub 50, the surface to be engraved can be horizontally positioned by rotating the car wheel hub 50, making processing more precise and convenient.

[0029] Another embodiment of this application differs from the above embodiments in that the structural scheme of the adjustment mechanism is different, such as... Figure 5 As shown, the adjusting mechanism includes: an upper threaded rod 41, a lower threaded rod 42, and a threaded sleeve 43; both the upper threaded rod 41 and the lower threaded rod 42 are provided with external threads, and the thread directions are opposite; the threaded sleeve 43 is provided with an internal thread wound in a single direction; the upper end of the upper threaded rod 41 is hinged to the right side of the adjusting block 22, and the lower end of the upper threaded rod 41 is threaded to the upper end of the threaded sleeve 43; the lower end of the lower threaded rod 42 is hinged to the right side of the base 21, and the upper end of the lower threaded rod 42 is threaded to the lower end of the threaded sleeve 43; so that when the threaded sleeve 43 rotates, the upper threaded rod 41 and the lower threaded rod 42 move towards each other or away from each other. When the adjustment mechanism is the above-mentioned threaded adjustment telescopic structure, its characteristic is that when adjusting the flip angle of the adjustment block 22, only the threaded sleeve 43 needs to be rotated, which is convenient and labor-saving, and the adjustment angle is linear; however, compared with the above-mentioned pin-type structure, the disadvantage of the threaded adjustment telescopic structure is that the adjustment range is relatively small, and the adjustment efficiency is relatively low when the adjustment range is too large.
