Abstract
Description
Technical Field
[0001] This utility model relates to the field of die casting processing equipment, and in particular to a pin-type engraving machine for marking die castings. Background Technology
[0002] In the die-casting production process, to facilitate product traceability, management, and identification, it is usually necessary to engrave marking information on the surface of the die-cast parts, such as product model, production batch, and production date. Currently, the two most common marking methods for die-cast parts are laser marking and pin engraving. Pin engraving machines have also found some application in the field of die-cast part marking due to their lower cost and ease of maintenance.
[0003] However, the existing pin-type engraving machine's fixing structure can only fix die-cast parts with a single shape (straight or curved), and cannot simultaneously meet the needs of fixing die-cast parts with different shapes (straight or curved), thus its applicability is not high.
[0004] To address the aforementioned technical deficiencies, a solution is proposed that allows for the simultaneous use of two different sides of the fixing plate to fix die-cast parts of different shapes (straight or curved), thus offering high applicability. Utility Model Content
[0005] The purpose of this invention is to provide a needle-type engraving machine for marking die-cast parts, in order to solve the problems mentioned above.
[0006] The objective of this utility model can be achieved through the following technical solution: a pin-type engraving machine for marking die-cast parts, comprising: A needle-type engraving machine assembly includes a platform, a first linear motor symmetrically mounted on the top of the platform, a support bar installed inside the first linear motor, a second linear motor installed on the top of the support bar, a mounting plate installed inside the second linear motor, an electric telescopic rod installed at the bottom of the mounting plate, and a needle-type engraving head installed at the bottom of the electric telescopic rod. The fixing assembly includes a connecting groove formed on the top of the platform, a drive motor mounted on the outer wall of the platform, a bidirectional lead screw fixed to the output end of the drive motor and movably passing through the outer wall of the platform and movably disposed inside the connecting groove, two sets of lead screw nuts mounted on the bidirectional lead screw, two sets of connecting strips correspondingly fixed to the outer walls of the two sets of lead screw nuts, and two sets of fixing plates correspondingly disposed on the top of the two sets of connecting strips.
[0007] Preferably, the top of the connecting strip has a movable hole, and the bottom of the fixing plate has a movable component that is movably disposed inside the movable hole; The two sides of the fixing plate are respectively straight and curved. The two sets of lead screw nuts are installed in two different threaded areas of the bidirectional lead screw.
[0008] Preferably, the top of the connecting strip has a first locking hole and a second locking hole, and the top of the fixing plate has a threaded hole, with a threaded rod that engages inside the second locking hole being threaded into the threaded hole.
[0009] Preferably, a knob is fixed to the top of the threaded rod.
[0010] Preferably, it also includes a cushioning component, which includes a slot formed at the top of the platform, a connecting plate disposed at the bottom of the platform, and a cushioning sponge installed on top of the connecting plate and located inside the slot.
[0011] Preferably, the outer wall of the connecting plate is fixed with a connecting lug, the top of the connecting lug is fixed with a fixed telescopic rod, the top of the fixed telescopic rod is fixed to the bottom of the platform, and the outer wall of the fixed telescopic rod is provided with a spring.
[0012] Preferably, the two ends of the spring are fixed to the top of the connecting ear and the bottom of the platform, respectively.
[0013] The beneficial effects of this utility model are: 1. Since the two sides of the fixing plate are respectively straight and curved, and the fixing plate is movably set in the movable hole of the connecting strip using a movable part, the fixing plate can be rotated to adjust the two different sides of the fixing plate. Then, the threaded locking rod is driven to move downward using a knob. When the threaded locking rod is engaged in the second locking hole, the curved side of the fixing plate will face the die-casting part. Therefore, the fixing plate can be used to fix die-casting parts with a curved shape. If the threaded locking rod is engaged in the first locking hole, the straight side of the fixing plate will face the die-casting part. Therefore, the fixing plate can be used to fix die-casting parts with a straight shape. Compared with the existing ones, this utility model can simultaneously meet the needs of fixing die-casting parts with different shapes (straight or curved) by switching the two different sides of the fixing plate, and has high applicability.
[0014] 2. During the processing of die-cast parts, the telescopic rod will retract under the action of the spring. When the telescopic rod retracts, it will cause the buffer sponge to come into contact with the bottom of the die-cast part. The buffer sponge can absorb the vibration generated during the processing of the die-cast part, thereby reducing the noise during the processing of the die-cast part and helping to improve the processing environment of the die-cast part.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1: The application background of this utility model is that the fixing structure of the existing needle-type engraving machine can only fix die-cast parts with a single shape (straight or curved), and cannot simultaneously meet the fixing needs of die-cast parts with different shapes (straight or curved), so its applicability is not high; the technical solution of this utility model is to solve the problem of how to simultaneously meet the fixing needs of die-cast parts with different shapes (straight or curved); Please see Figures 1-3As shown, this embodiment is a pin-type engraving machine for marking die-cast parts, including: a pin-type engraving machine assembly 100, including a platform 101, a first linear motor 102 symmetrically mounted on the top of the platform 101, a support bar 103 mounted inside the first linear motor 102, a second linear motor 104 mounted on the top of the support bar 103, a mounting plate 105 mounted inside the second linear motor 104, an electric telescopic rod 106 mounted at the bottom of the mounting plate 105, and a pin-type engraving head 107 mounted at the bottom of the electric telescopic rod 106; and a fixing assembly 200, including a connecting groove 201 formed on the top of the platform 101, a drive motor 202 mounted on the outer wall of the platform 101, and a bidirectional lead screw 203 fixed to the output end of the drive motor 202, movably passing through the outer wall of the platform 101, and movably disposed inside the connecting groove 201. Two sets of screw nuts 204 are installed on the bidirectional screw 203; two sets of connecting strips 205 are fixed to the outer walls of the two sets of screw nuts 204; and two sets of fixing plates 206 are set on the top of the two sets of connecting strips 205. The top of the connecting strips 205 has a movable hole 207, and the bottom of the fixing plate 206 has a movable part 208 that is movably set inside the movable hole 207. The two sides of the fixing plate 206 are respectively straight and curved. The two sets of screw nuts 204 are installed on two different threaded areas of the bidirectional screw 203. The top of the connecting strips 205 has a first locking hole 209 and a second locking hole 210. The top of the fixing plate 206 has a threaded hole 211. The threaded hole 211 is threadedly connected to a threaded rod 212 that engages inside the second locking hole 210. The top of the threaded rod 212 is fixed with a knob 213. Since the two sides of the fixing plate 206 are respectively straight and curved, and the fixing plate 206 is movably set in the movable hole 207 of the connecting strip 205 by the movable part 208, the fixing plate 206 can be rotated to adjust the two different sides of the fixing plate 206. Then, the screw rod 212 is driven to move downward by the knob 213. When the screw rod 212 is engaged in the second locking hole 210, the curved side of the fixing plate 206 will face the die casting. Therefore, the fixing plate 206 can be used to fix the die casting with a curved shape. If the screw rod 212 is engaged in the first locking hole 209, the straight side of the fixing plate 206 will face the die casting. Therefore, the fixing plate 206 can be used to fix the die casting with a straight shape. Compared with the existing ones, this utility model can simultaneously meet the needs of fixing die castings with different shapes (straight or curved) by switching the two different sides of the fixing plate 206, and has high applicability.
[0019] Example 2: Please refer to Figure 1 , Figure 2 , Figure 4As shown, this embodiment is a pin-type engraving machine for marking die-cast parts, and also includes a buffer assembly 300. The buffer assembly 300 includes a slot 301 opened on the top of the platform 101, a connecting plate 302 set at the bottom of the platform 101, and a buffer sponge 303 installed on the top of the connecting plate 302 and located inside the slot 301. A connecting ear 304 is fixed on the outer wall of the connecting plate 302, and a fixed telescopic rod 305 is fixed on the top of the connecting ear 304. The top of the fixed telescopic rod 305 is fixed to the bottom of the platform 101. A spring 306 is provided on the outer wall of the fixed telescopic rod 305, and the two ends of the spring 306 are fixed to the top of the connecting ear 304 and the bottom of the platform 101 respectively. When processing the die casting, the telescopic rod is driven to retract under the action of the spring 306. When the telescopic rod retracts, it drives the buffer sponge 303 to abut against the bottom of the die casting. The buffer sponge 303 can absorb the vibration generated during the processing of the die casting, thereby reducing the noise during the processing of the die casting and helping to improve the processing environment of the die casting.
[0020] In summary, please refer to the following: Figures 1-4 Before processing the die-cast part, the fixing plate 206 is adjusted according to the shape of the die-cast part. Since the two sides of the fixing plate 206 are respectively straight and curved, and the fixing plate 206 is movably set in the movable hole 207 of the connecting strip 205 using the movable part 208, the fixing plate 206 can be rotated to adjust the two different sides of the fixing plate 206. Then, the threaded locking rod 212 is driven to move downward using the knob 213. When the threaded locking rod 212 is engaged in the second locking hole 210, the curved side of the fixing plate 206 will face the die-cast part, so the fixing plate 206 can be used to fix the die-cast part with a curved shape. If the threaded locking rod 212 is engaged in the first locking hole 209, the straight side of the fixing plate 206 will face the die-cast part. Therefore, the fixing plate 206 can be used to fix the die-cast part with a straight surface shape. After the fixing plate 206 is adjusted, the die-cast part is placed on the top of the platform 101 and the drive motor 202 is started. The drive motor 202 drives the bidirectional lead screw 203 to work. Under the drive of the bidirectional lead screw 203, the two lead screw nuts 204 drive the two fixing plates 206 to move in opposite directions. When the two fixing plates 206 abut against the die-cast part, the die-cast part can be fixed. Then, the first linear motor 102, the second linear motor 104, the electric telescopic rod 106, and the needle-type engraving head 107 are started. The first linear motor 102, the second linear motor 104, and the electric telescopic rod 106 can adjust the position of the needle-type engraving head 107, and then work with the needle-type engraving head 107 to engrave the die-cast part.
[0021] As can be seen from Embodiments 1 and 2, on the one hand, by switching the two different sides of the fixing plate 206, it is possible to simultaneously meet the needs of fixing die-cast parts with different shapes (straight or curved), thus having high applicability; on the other hand, when processing the die-cast part, the telescopic rod will be driven to retract under the action of the spring 306. When the telescopic rod retracts, it will drive the buffer sponge 303 to abut against the bottom of the die-cast part. The buffer sponge 303 can absorb the vibration generated during the processing of the die-cast part, thereby reducing the noise during the processing of the die-cast part and helping to improve the processing environment of the die-cast part.
[0022] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
