Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, and more specifically, to a marking fixture with fixed-angle error prevention. Background Technology

[0002] When marking products, the marking area is specific to the product, so this area must be identified manually when placing the product. In practice, the operator first roughly positions the product to the approximate marking location, then activates the laser marking machine's focusing function. The operator visually inspects the laser marking machine's cursor point and manually adjusts and moves the product multiple times. The center of the workpiece's marking position is roughly aligned with the laser marking machine's focusing cursor point before the machine is started to print the mark. This process generally ensures the mark roughly falls within the required marking area, but it cannot completely guarantee that the mark will not exceed the specified marking area, leading to defective products.

[0003] The current processing method is manual visual orientation:

[0004] Manual visual positioning relies entirely on manual judgment to determine whether the product is placed in the correct position. This method requires high technical skills to correct the product position, often resulting in incorrect marking positions during actual processing. Furthermore, this method is labor-intensive, inefficient, and cannot guarantee the quality of marking.

[0005] Defect 1: Manual positioning and finding of the corner positions is labor-intensive and has low marking efficiency;

[0006] Defect 2: It is impossible to intuitively judge whether the marking position is adjusted properly. It can only be identified after processing whether the marking position meets the requirements, which affects processing efficiency and product quality. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a marking fixture with fixed angular direction error prevention, which can effectively center the product through the centering block, and accurately position the product angularly through the fixing device, thus greatly improving the marking quality and efficiency; the structure is simple and the practicality is strong.

[0008] The solution adopted by this utility model to solve the technical problem is:

[0009] A marking fixture with fixed-angle error prevention, used in conjunction with a marking device, includes a base, a centering block mounted on the base and having a V-groove, and a fixing device mounted on the centering block for fixing the product.

[0010] In some possible implementations, the fixing device includes a support rod mounted on a centering block and arranged vertically, a support plate mounted on the support rod and rotatably engaged with the support rod about the vertical direction, and a directional pin mounted on the support plate and slidably engaged with the support plate vertically.

[0011] In some possible implementations, the support rod includes a main rod detachably mounted on the centering block and arranged vertically, and a secondary rod disposed at the end of the main rod away from the centering block; the support plate is fitted onto the outside of the secondary rod; the outer diameter of the secondary rod is smaller than the outer diameter of the main rod and cooperates with the main rod to form a support surface for supporting the support plate.

[0012] In some possible implementations, the support plate is provided with a through hole for use with a secondary rod, which is fitted into the through hole.

[0013] In some possible implementations, the fixing device further includes a locking element for securing the support plate and the auxiliary rod.

[0014] In some possible implementations, the locking element includes a screw rod disposed on the side of the auxiliary rod away from the main rod, a locking nut that cooperates with the screw rod, and a locking bolt mounted on the support plate with one end passing through the support plate and abutting against the auxiliary rod; the screw rod, auxiliary rod, and main rod are coaxially arranged.

[0015] In some possible implementations, the directional pin includes a pin body that mates with the product insert, a threaded rod mounted on the pin body and slidingly engaging with a support plate, and a limiting nut fitted around the outside of the threaded rod and engaging with it; the threaded rod is arranged vertically.

[0016] In some possible implementations, a vertical hole is provided on the support plate, and the threaded rod is fitted into the vertical hole with a small clearance fit.

[0017] In some possible implementations, the included angle formed by the two sides of the V-groove is 90°.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention achieves accurate centering of the product during marking by ensuring that the two sides of the V-groove are in close contact with the outer surface of the product, thus limiting product deviation.

[0020] This utility model uses a directional pin that matches the product and is inserted into one of the sets of pin holes evenly distributed around the circumference of the product. This not only prevents angular deviation during product marking and avoids errors, but also ensures that the marking requirements are met. Furthermore, after marking is completed, the directional pin can be quickly removed from the product pin hole, enabling continuous processing.

[0021] This utility model has a simple structure and is highly practical. Attached Figure Description

[0026] The present invention will now be described in detail.

[0027] like Figures 1-2 As shown:

[0028] A marking fixture with fixed-angle error prevention, used in conjunction with a marking device, includes a base 6, a centering block 1 mounted on the base 6 and having a V-groove 11, and a fixing device mounted on the centering block 1 for fixing the product 5.

[0029] In use, first push product 5 so that the outer circle of product 5 fits against the two sides of V-groove 11; then fix product 5 with a fixing device; then use a marking device to mark. When marking, you only need to control the cursor point to coincide with the center of the marking position on product 5; there is no need to adjust the position of product 5; thus greatly improving the marking efficiency.

[0030] In some possible implementations, in order to effectively achieve accurate orientation and fixation of product 5 by means of a fixing device, the fixing device includes a support rod 2 mounted on the centering block 1 and arranged vertically, a support plate 3 mounted on the support rod 2 and rotatably engaged with the support rod 2 about the vertical direction, and a directional pin 4 mounted on the support plate 3 and slidably engaged with the support plate 3 in the vertical direction.

[0031] The support plate 3 and the support rod 2 rotate vertically to cooperate, which will effectively prevent interference with the product 5 when it is pushed. In use, by rotating the support plate 3 to the side away from the V-groove 11, interference can be effectively avoided, thereby achieving efficient and rapid accurate centering of the product 5.

[0032] After product 5 is installed in place, the support plate 3 is rotated and the directional pin 4 is controlled to move vertically and insert into the pin hole set on product 5. The cooperation between the directional pin 4 and the pin hole can not only effectively control the angular position of product 5 and avoid angular offset, but also effectively prevent the marking position from not meeting the requirements of product 5.

[0033] In some possible implementations, in order to effectively achieve the support and rotational cooperation between the support rod 2 and the support plate 3, the support rod 2 includes a main rod 21 that is detachably mounted on the centering block 1 and arranged vertically, and a secondary rod 22 disposed at the end of the main rod 21 away from the centering block 1; the support plate 3 is fitted on the outside of the secondary rod 22; the outer diameter of the secondary rod 22 is smaller than the outer diameter of the main rod 21 and cooperates with the main rod 21 to form a support surface for supporting the support plate 3.

[0034] The main rod 21 is a round rod that is set vertically and detachably connected to the base 6. The auxiliary rod 22 is also a round rod and is coaxially connected to the main rod 21, so that the side of the main rod 21 away from the base 6 will form a support surface to support the support plate 3. The auxiliary rod 22 is fitted into the support plate 3 to achieve rotational engagement around the vertical direction.

[0035] In some possible implementations, the support plate 3 is provided with a through hole for use with a secondary rod 22, which is fitted into the through hole.

[0036] In some possible implementations, in order to effectively achieve the rotation of the support plate 3 to the designated position, the support plate 3 and the auxiliary rod 22 are fixed to restrict the rotation of the support plate 3; the fixing device also includes a locking member 7 for fixing the support plate 3 and the auxiliary rod 22.

[0037] In some possible implementations, the locking member 7 includes a screw 71 disposed on the side of the auxiliary rod 22 away from the main rod 21, a locking nut 72 that cooperates with the screw 71 and is located above the support plate 3, and a locking bolt 73 that is mounted on the support plate 3 and has one end that passes through the support plate 3 and abuts against the auxiliary rod 22; the screw 71, the auxiliary rod 22, and the main rod 21 are coaxially arranged.

[0038] After the support plate 3 is rotated to the designated position, the locking nut 72 is tightened to move it closer to and fit against the support plate 3. At the same time, the locking bolt 73 is tightened so that the end of the locking bolt 73 near the auxiliary rod 22 fits against the auxiliary rod 22, thereby achieving locking and fixing of the support plate 3 in both the vertical and horizontal directions.

[0039] In some possible implementations, the directional pin 4 includes a pin body 41 that inserts into the product 5, a threaded rod 42 mounted on the pin body 41 and slidingly engaged with the support plate 3, and a limiting nut 43 fitted on the outside of the threaded rod 42 and used in conjunction with the threaded rod 42; the threaded rod 42 is arranged vertically; the threaded rod 42 is detachably connected to the pin body 41, and different pin bodies 41 can be used for different products 5;

[0040] The directional pin 4 and the support plate 3 slide vertically together, so that the directional pin 4 can be effectively inserted into the pin hole of the product 5 to fix the product 5.

[0041] In use, by controlling the vertical movement of the limit nut 43, the threaded rod 42 is driven to slide vertically, thereby enabling the pin body 41 to be inserted or pulled out; the limit nut 43 will prevent the threaded rod 42 from falling off the support plate 3.

[0042] It should be noted that: Product 5 is a synchronizer, and the pin hole is a hole that the synchronizer itself has. The holes are evenly spaced along the circumference of Product 5. The diameter of the pin hole is different on different synchronizers. Through the cooperation between the pin body 41 and the pin hole, error prevention is effectively achieved.

[0043] In some possible implementations, in order to effectively achieve vertical sliding between the threaded rod 42 and the support plate 3, a vertical hole is provided on the support plate 3, and the threaded rod 42 is fitted into the vertical hole with a small clearance.

[0044] In some possible implementations, the included angle formed by the two sides of the V-groove 11 is 90°, thereby effectively centering the product 5 by fitting the two sides against the outer circle of the product 5, achieving accuracy in the marking center position, and limiting the product 5 from shifting during marking.

[0045] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
