Description

Technical Field

[0001] This utility model relates to the field of mechanical polishing, and in particular to a mechanical polishing fixture for through-hole inner holes. Background Technology

[0002] After drilling the part, it needs to be polished. When the worker places the part in the polishing area, the limit device needs to be manually switched on and off. During long-term operation, the worker may fail to close the limit device for various reasons. This poses a certain safety hazard and may also result in defects. Therefore, based on this technical problem, we designed a mechanical polishing fixture for through holes. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a mechanical polishing fixture for through holes, including a polishing table, a part groove, and a polishing wheel. The polishing table has a part groove on its upper side, and a through hole is provided at the position corresponding to the through hole of the part. A polishing motor is provided above the part groove, and a polishing wheel is provided below the polishing motor. The polishing motor is driven to move up and down by a power device. A telescopic groove is provided on one side of the part groove, and a retractable limiting plate is provided in the telescopic groove. The limiting plate extends into the upper part groove to limit the part.

[0004] The power unit includes a slide groove, a slider, a lead screw, and a lead screw motor; a slide groove is vertically arranged on one side of the polishing table, and a slider that can slide up and down is arranged in the slide groove. One side of the slider is connected to the polishing motor. A lead screw is vertically arranged in the slide groove, passes through the slider and is threaded to it, and the top of the lead screw is connected to the lead screw motor.

[0005] The polishing motor is connected to a "7"-shaped linkage plate on one side. One side of the linkage plate is connected to the slider. When the limiting plate is not extended into the part slot, the other side of the limiting plate extends into the movement path below the linkage plate. An auxiliary pushing block in the shape of a right triangle is provided above the side of the limiting plate near the linkage plate. The limiting plate is pushed into the part slot by the downward movement of the linkage plate.

[0006] The lower side of the linkage plate pushes the auxiliary push block with rounded corners.

[0007] A vertical plate is provided above the part slot on the side of the telescopic groove. Two telescopic rods are horizontally and symmetrically arranged on the side of the auxiliary push block facing the vertical plate. Movable holes are provided at the corresponding positions of the vertical plate and the telescopic rods. The telescopic rods always move back and forth through the movable holes. A spring is sleeved on the outer ring of the telescopic rod between the vertical plate and the auxiliary push block. The two ends of the spring are connected to the vertical plate and the auxiliary push block respectively. Under the action of the spring force, when the linkage plate is lifted upward, the limiting plate does not limit the part.

[0008] The beneficial effects of this utility model are as follows: When the polishing motor is driven by the lead screw motor to grind the parts, it also drives the linkage plate, which in turn drives the limit plate to push out and limit the parts. This eliminates the need for workers to open and close the limit device separately when grinding the parts. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments: See Figs. 1-2 .

[0012] This utility model discloses a mechanical polishing fixture for through-hole inner holes, including a polishing table 1, a part groove 2, and a polishing wheel 3. The polishing table has a part groove on its upper side, and a through hole 4 is provided at the position corresponding to the through hole of the part. A polishing motor 5 is provided above the part groove, and a polishing wheel is provided below the polishing motor. The polishing motor is driven to move up and down by a power device. A telescopic groove 6 is provided on one side of the part groove, and a retractable limiting plate 7 is provided in the telescopic groove. The limiting plate extends into the upper part groove to limit the part.

[0013] The power unit includes a slide groove 8, a slider 9, a lead screw 10, and a lead screw motor 11; a slide groove is vertically arranged on one side of the polishing table, and a slider that can slide up and down is arranged in the slide groove. One side of the slider is connected to the polishing motor. A lead screw is vertically arranged in the slide groove, and the lead screw passes through the slider and is threaded to it. The top of the lead screw is connected to the lead screw motor.

[0014] The polishing motor is connected to a "7"-shaped linkage plate 12 on one side. One side of the linkage plate is connected to the slider. When the limiting plate does not extend into the part slot, the other side of the limiting plate extends into the movement path below the linkage plate. An auxiliary pushing block 13 in the shape of a right triangle is provided above the side of the limiting plate near the linkage plate. The limiting plate is pushed into the part slot by the downward movement of the linkage plate.

[0015] The lower side of the linkage plate pushing the auxiliary push block is rounded by 14.

[0016] A vertical plate 15 is provided above the part slot on the side of the telescopic groove. Two telescopic rods 16 are horizontally and symmetrically arranged on the side of the auxiliary push block facing the vertical plate. Movable holes are provided at the corresponding positions of the vertical plate and the telescopic rods. The telescopic rods always move back and forth through the movable holes. A spring 17 is sleeved on the outer ring of the telescopic rod between the vertical plate and the auxiliary push block. The two ends of the spring are connected to the vertical plate and the auxiliary push block respectively. Under the action of the spring force, when the linkage plate is lifted upward, the limiting plate does not limit the part.

[0017] Specific operations First, place the part to be polished in the part slot 2, start the polishing motor 5 and the lead screw motor 11. The lead screw motor 11 drives the polishing motor 5 to move downward. At the same time, the linkage plate 12 pushes the auxiliary push block 13 to push the limit plate 7 forward to limit the part. After the drilling is completed, the lead screw motor 11 drives upward. Under the action of the spring, the limit plate 7 retracts.
