For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.

[0029] See also Figures 1 to 5 The utility model discloses a part engraving positioning fixture, which comprises:

[0030] Base 1;

[0031] A tank body 2, wherein the tank body 2 is formed by an inward depression of one end surface of the base 1;

[0032] A magnetic adsorption platform 3, the magnetic adsorption platform 3 is embedded in the tank body 2, and the side of the magnetic adsorption platform 3 facing away from the bottom wall of the tank body 2 is used to place parts. An electromagnet is provided in the magnetic adsorption platform 3, and a knob 4 for adjusting the current in the electromagnet is also provided on the side wall thereof;

[0033] A positioning block 5 is slidably connected to a side wall of the slot body 2 along the length direction of the slot body 2 .

[0034] With the above structure, before the part is engraved, it is only necessary to place the part on the magnetic adsorption platform and slide the positioning block 5 along the length direction of the groove body 2 so that the surface facing the part abuts against the part and limits the part from the side; the positioning block 5 is arranged in a sliding connection with the side wall of the groove body 2, which also ensures that the fixture can be used for side positioning of parts of different specifications; after the positioning block 5 abuts against the part, the current in the electromagnet can be adjusted by the knob 4, so as to realize the rapid adjustment of the magnetic force of the electromagnet in the magnetic adsorption platform, so that the magnetic attraction force is suitable for parts of different specifications, stably adsorbs the parts, and ensures that the parts are stably limited during the engraving process.

[0035] See also Figures 1 to 5 Specifically, in this embodiment, the base 1 is generally rectangular, and its upper end surface is an inclined surface that gradually decreases from the back to the front, and its upper end surface is recessed downward to form a groove 2, and the groove 2 has the same length as the base 1 in the left and right direction. The lower part of the magnetic adsorption table 3 is rectangular, and its table top is "V" shaped to carry parts. Of course, in other embodiments, the table top of the magnetic adsorption table 3 can also be set to other shapes according to the shape of the part to be engraved.

[0036] See also Figure 1 , Figure 2 as well as Figure 4 Specifically, in the present embodiment, the magnetic adsorption platform 3 and the positioning block 5 are both detachably connected to the trough body 2. The purpose of adopting the detachable connection method is to enable the magnetic adsorption platform to be replaced in time when a magnetic adsorption failure occurs and the positioning block 5 is worn, thereby reducing the maintenance difficulty of the entire part engraving positioning fixture. For example, after the magnetic adsorption platform 3 is embedded in the trough body 2, two groups of 4 screws are used to fasten the magnetic adsorption platform 3 from the front and back sides of the base 1. At the same time, bolts can be used to pass through the rear side wall of the base 1 from the back to the front and fasten it to the positioning block 5. Of course, in other embodiments, the magnetic adsorption platform 3 and the positioning block 5 can also be connected to the trough body 2 in other detachable ways.

[0037] See also Figures 1 to 3Specifically, in the present embodiment, in the vertical direction, the magnetic adsorption platform 3 is located between the positioning block 5 and the bottom wall of the trough body 2. In other words, the positioning block 5 is arranged on the portion of the rear side wall of the trough body 2 which is higher than the table surface of the magnetic adsorption platform 3, so that when it slides relative to the trough body 2 in the left and right directions, the magnetic adsorption platform 3 will not interfere with it.

More specifically, in the left-right direction, the right end of the magnetic adsorption platform 3 is located in the slot body 2, so that a certain accommodating space is formed between the right end of the magnetic adsorption platform 3 and the slot body 2, so that the parts placed on the magnetic adsorption platform 3, if there is a downward extending part at its right end, can be stably limited, that is, the left side of the downward extending part of the part can be against the right end face of the magnetic adsorption platform 3, and the sliding positioning block 5 can be against the upper right end face of the part, so that the right side of the magnetic adsorption platform and the left side of the positioning block 5 cooperate with each other to limit the part in the left-right direction. Further, the magnetic force of the electromagnet can be adjusted by the knob 4, and the part can be stably adsorbed on the magnetic adsorption platform 3 for the engraving operation.

[0039] Please continue reading Figures 1 to 5 Specifically, in this embodiment, the knob 4 is arranged on the left end side wall of the magnetic adsorption platform 3, so that no extra avoidance portion is required on the base 1, the processing shape is simpler, and the overall forming and assembly of the part engraving positioning fixture is more convenient.
