Description

Technical Field

[0001] The utility model belongs to the technical field of top hammer processing, and in particular relates to a top hammer inclined surface grinding device. Background Art

[0002] The top hammer includes 4 large bevels and 4 small bevels, and the large and small bevels of the top hammer are usually processed by surface grinding.

[0003] For example, Chinese patent application number 202311039465.3 discloses an auxiliary device for grinding the bevel of a top hammer, and Chinese patent application number 202021472339.9 discloses a fixed fixture for grinding a top hammer. In both patents, a V-shaped groove is provided on a fixed seat, and the V-shaped groove of the fixed seat is in contact with the positioning sleeve, so that the top hammer in the positioning sleeve is tilted, so that the large and small bevels of the top hammer are processed by the grinding mechanism.

[0004] In the above two solutions, after completing the processing of one large bevel or small bevel, the entire positioning sleeve needs to be turned over to realize the processing of another large bevel or small bevel. However, some top hammers are heavy, ranging from 50kg to 100kg. If the eight bevels of the top hammer are to be processed, the operator needs to adjust the inclination angle of the positioning sleeve twice and turn the positioning sleeve eight times, resulting in a high labor intensity for the operator. Utility Model Content

[0005] The utility model aims to provide a top hammer inclined surface grinding device which can reduce the labor intensity of operators.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a top hammer bevel grinding device, including a positioning mechanism and a grinding mechanism located on one side of the positioning mechanism, the positioning mechanism including a horizontally arranged workbench, the workbench is flip-connected with a flip plate, a flip drive is provided on the side of the flip plate deviating from the flip connection, the flip drive is arranged on the workbench and controls the angle between the flip plate and the workbench by lifting the flip plate, the flip plate is provided with a positioning sleeve with an axis perpendicular to the flip plate and used to place the top hammer workpiece, the positioning sleeve is rotatably connected to the flip plate.

[0007] In actual operation, the operator puts the top hammer into the positioning sleeve and adjusts the rotation angle of the positioning sleeve, then turns the driver to lift the flip plate, so that an angle is formed between the flip plate and the workbench, so that the top hammer is tilted, and then it is polished through the grinding mechanism. After completing the processing and grinding of a small bevel (or a large bevel) of the top hammer; the operator rotates the positioning sleeve 90° to realize the processing and grinding of another small bevel (or a large bevel), and repeats the above operation to complete the processing and grinding of 4 small bevels (or large bevels). The operator adjusts the stroke of the flip driver to change the tilt angle of the top hammer, and then repeats the above operation to complete the processing and grinding of the large bevel (or a small bevel) of the top hammer.

[0008] The angle between the positioning sleeve and the flip plate can be fixed by setting 4 screw holes between the positioning sleeve and the flip plate, and the positioning sleeve can be locked with screws every 90° rotation, or the positioning sleeve can be rotated by a dividing plate, etc. The grinding mechanism is any existing grinding mechanism that can perform surface grinding on the top hammer.

[0009] This solution controls the angle between the flip plate and the workbench through the flip driver to achieve the processing and positioning of the large and small bevels of the top hammer, and the four bevels of the top hammer can be processed through the rotation connection between the positioning sleeve and the flip plate. Compared with the comparative document, this solution does not require the operator to flip and carry the positioning sleeve, and the operation is simple, reducing the labor intensity of the operator.

[0010] Preferably, the flip driver is an electric push rod, a fixed end of the electric push rod is rotationally connected to the workbench, and an output end of the electric push rod is rotationally connected to the flip plate.

[0011] The electric push rod can control the extension length of the electric push rod through the signal of motor rotation, so as to facilitate the calculation of the angle between the flip plate and the workbench; the fixed end of the electric push rod is rotatably connected to the workbench, and the output end of the electric push rod is rotatably connected to the flip plate, so that the flip plate will not be stuck with the electric push rod when flipping.

[0012] Preferably, a support block is provided between the flip plate and the workbench, the lower end of the support block is detachably fixed to the workbench, and the upper end of the support block is in contact with the flip plate.

[0013] The support block can support the flip plate after flipping, thereby reducing the load of the flip driver. At the same time, the support block can be detachably fixed, and different support blocks can be used for support according to different flipping angles.

[0014] Preferably, an inclined surface is provided at the upper end of the support block, the inclined surface is in contact with the end surface of the flip plate, and the inclination angle of the inclined surface is the same as the included angle between the flip plate and the workbench.

[0015] The angle of the inclined surface is the same as the included angle between the turning plate and the workbench, and the contact between the inclined surface and the end surface of the turning plate can increase the positioning effect.

[0016] Preferably, a threaded locking hole and a locking piece are provided between the upper end flip plates of the support block.

[0017] The locking between the support block and the flip plate is achieved through the cooperation of the locking piece and the locking hole, thereby increasing the positioning effect.

[0018] Preferably, a dividing plate is provided on the flip plate, and the positioning sleeve is provided on the dividing plate.

[0019] The rotation of the positioning sleeve is achieved through the indexing plate, which makes it easy for the operator to control the rotation of the positioning sleeve; the indexing plate can control the rotation angle through a servo motor.

[0020] Preferably, the circumferential outer edge of the positioning sleeve is rectangular in shape, and the upper end of the positioning sleeve is provided with four avoidance cone surfaces corresponding one to one with the inclined surfaces of the top hammer.

[0021] The grinding wheel of the grinding mechanism can be given way by avoiding the conical surface to avoid contact between the grinding wheel and the positioning sleeve.

[0022] The utility model has the advantage of reducing the labor intensity of operators. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end of the support block 6 is a plane and is detachably fixed to the workbench 2 by bolts. The upper end of the support block 6 is provided with an inclined surface. The inclined surface of the support block 6 contacts and cooperates with the lower end surface of the flip plate 3, and the inclination angle of the inclined surface of the support block 6 is the same as the angle between the flip plate 3 and the workbench 2. A locking hole (not shown in the figure) is provided at the upper end of the support block 6. The locking hole has an internal thread structure. The extension direction of the locking hole is perpendicular to the upper end inclined surface of the support block 6. The flip plate 3 is provided with a through hole. The locking member (not shown in the figure) passes through the through hole and is threadedly matched with the locking hole. Among them, the locking member is also a bolt.
