Description

Technical Field

[0001] The utility model relates to the field of automobile mold grinding, and relates to a surface grinding device for automobile molds with an angle adjustment function. Background Technique

[0002] Automobile mold grinding is one of the very important technological steps in manufacturing automobile parts. It directly affects the quality and precision of the final product. Automobile mold grinding requires high precision, high efficiency and stability;

[0003] It is found that the publication (announcement) number: CN216179297U discloses a surface grinding device for automobile molds with an angle adjustment function. In this technology, "a frame and a mold fixture are disclosed. The mold fixture is installed at the inner bottom of the frame. A first telescopic push rod is fixedly installed at the inner top of the frame. The piston rod of the first telescopic push rod is fixedly connected to a substrate. The bottom of the substrate is fixedly installed with symmetrically arranged first electric sliding rails. The substrate is slidably installed with a rotating base through the first electric sliding rails and other technical solutions, which have the function of adapting the position of the automobile mold clamped on the mold fixture for subsequent multi-angle grinding processes. Through the settings of structures such as an air pump, a second electric sliding rail, a corrugated pipe and an adjustment motor, under the movement adjustment of the second electric sliding rail and the angle adjustment of the adjustment motor, the spraying position of the spraying head can be adjusted, so as to blow air at the position of the residual grinding debris after the mold is ground, so that the debris does not accumulate at the grinding position and affect the grinding effect of the mold" and other technical effects;

[0004] However, in the above-mentioned comparative document, the cooperation of a second telescopic push rod and a damping telescopic rod is used to adjust the angle of the grinder. However, when adjusting the grinder, only a single-angle adjustment of the grinder can be performed, and an over-angle adjustment cannot be performed. When encountering a relatively complex automobile mold, a single-angle adjustment may affect the grinding effect of the automobile mold. At the same time, during the long-term use of the grinder, in the above-mentioned comparative document, when the angle of the grinder deviates, it is impossible to visually observe it, which may affect the grinding effect. Moreover, during grinding, the clamping part of the mold by the clamping plate may not be ground, so that the staff needs to adjust the position of the mold, and the adjustment of the mold will affect the grinding efficiency;

[0005] To solve the above problems, a surface grinding device for automobile molds with an angle adjustment function is proposed in the utility model. Content of the Utility Model

[0006] The utility model aims at the technical problems existing in the prior art and provides a surface grinding device for automobile molds with an angle adjustment function.

A spring is fixedly connected inside the fixing sleeve. One end of the spring is fixedly connected to a positioning rod. By setting the clamping structure, the clamping and positioning of the mold are realized, thereby avoiding the displacement of the mold, and further avoiding the shaking of the mold during grinding, which affects the grinding accuracy.

[0009] The placement table is slidably connected with a telescopic plate through the groove. The telescopic end of the telescopic plate is fixedly connected to the outer wall of the positioning rod. By setting the telescopic plate, the protection of the groove is realized, thereby avoiding the powder from falling into and affecting the movement of the flat linear motor, and further avoiding the damage of the flat linear motor.

[0010] A second electric telescopic rod is fixedly connected to the inner wall of the support frame. A positioning plate is fixedly connected to the telescopic end of the second electric telescopic rod. By setting the second electric telescopic rod and the positioning plate, the positioning of the mold is realized, thereby avoiding affecting the grinding effect of the mold.

[0011] A protective pad is fixedly connected to the side of the positioning plate away from the second electric telescopic rod. Anti-slip grooves are opened on the side of the protective pad away from the positioning plate, realizing the protection of the mold, thereby avoiding the waste of resources.

[0012] Bolts are arranged on the connecting sleeve. The bolts penetrate through the connecting sleeve. One end of the bolts penetrating through the connecting sleeve is threadedly connected with nuts. By setting the bolts and nuts, the disassembly and maintenance of the connecting sleeve are realized, thereby avoiding the difficulty of replacing the grinding device when the grinding device is damaged, which affects the work efficiency.

[0014] Through the mutual cooperation of the support frame, cylinder, clamping structure, connecting plate, first electric telescopic rod, connecting frame, servo motor, round rod, connecting sleeve, fixing plate and grinder, multi-angle adjustment of the grinder is realized. The telescopic of the first electric telescopic rod is used to adjust the angle of the grinder back and forth.

At the same time, with the cooperation of the angle rod and the angle disk, it is convenient for the staff to observe and adjust the position of the grinder after long-term use, so as to avoid affecting the grinding effect of the grinder.

One end of the bolt 18 passing through the connecting sleeve 9 is threadedly connected to a nut 19. The mutual cooperation of the bolt 18 and the nut 19 can realize the disassembly and repair of the connecting sleeve 9, thus preventing the grinder 11 from being difficult to replace and affecting the working efficiency when the grinder 11 is damaged.

[0033] Working principle:

[0034] For the automotive mold surface grinding device with an angle adjustment function, the staff places the mold on the placement table 301. The second electric telescopic rod 14 drives the positioning plate 15 and the protective pad 16 to move, and the mold is clamped and positioned through the protective pad 16. The flat linear motor 303 starts to drive the fixed sleeve 304 and the positioning rod 306 to move. The positioning rod 306 fits against the inner wall of the mold during movement, thereby positioning and fixing the mold. After the mold is fixed, the second electric telescopic rod 14 returns to its original position to avoid affecting the grinding of the mold surface. The air cylinder 2 drives the connecting plate 4 to move, making the grinder 11 approach the surface of the mold. When angle adjustment is required during grinding, the first electric telescopic rod 5 starts, causing the connecting frame 6 to tilt at an angle, thereby driving the grinder 11 to adjust the angle. At the same time, the rotation of the round rod 8 can also be driven by the rotating shaft of the servo motor 7. The rotation of the round rod 8 drives the movement of the connecting sleeve 9 and the grinder 11, thereby enabling the grinder 11 to perform multi-directional angle adjustment, and thus facilitating multi-directional angle grinding of the mold.
