Description

Technical Field

[0001] The utility model belongs to the technical field of forming equipment, and specifically relates to an adjustable broaching plate of a broaching forming machine. Background Art

[0002] The broaching forming machine, abbreviated as the broaching machine, is a mechanical device for processing the shapes of gears and racks. It uses the relative movement between the workpiece and the broaching plate to engrave the tooth shape of the broaching plate onto the workpiece, thereby forming the required tooth shape. Therefore, the broaching plate is one of the keys to the tooth forming of the workpiece. When the workpiece is processed into the required tooth shape, the upper and lower two broaching plates moving towards each other roll the workpiece in the middle, so that the surface of the workpiece is extruded with a broaching plate of a suitable specification.

[0003] A Chinese patent with the publication number CN214349339U discloses a broaching plate for a broaching machine, which consists of a mounting seat and a plate body. When in use, the plate body is directly fixed on the mounting seat, and then the mounting seat together with the plate body is mounted on the broaching machine, so that the two plate bodies are arranged in central symmetry. Finally, the broaching machine is used to drive the two plate bodies to move towards each other, and the tooth shape can be rolled out on the central shaft body.

[0004] However, in the technical solution of the above patent, the broaching plate needs to be replaced when processing tooth shapes of different specifications for the workpiece. It is impossible to use the same broaching plate to process tooth shapes of different specifications for the workpiece according to the processing requirements, and it cannot meet more processing requirements, having certain limitations. Summary of the Utility Model

[0005] In order to solve the technical problem that in the prior art, it is impossible to use the same broaching plate to process tooth shapes of different specifications for the workpiece according to the processing requirements, and it cannot meet more processing requirements, having certain limitations, the utility model provides an adjustable broaching plate of a broaching forming machine.

[0006] The purpose of the utility model can be realized by the following technical solutions:

[0007] An adjustable broaching plate of a broaching forming machine includes a fixed seat, which presents a structure with both ends protruding and an upper opening; a horizontal moving block is arranged inside the fixed seat; a vertical moving block is arranged above the horizontal moving block; teeth are provided above the vertical moving block; inclined surfaces are provided on the mutually approaching surfaces of the vertical moving block and the horizontal moving block, and the vertical moving block and the horizontal moving block are mutually attached.

[0008] The length of the horizontal moving block is less than that of the vertical moving block; symmetrically arranged threaded holes are provided at both ends of the fixed seat corresponding to the position of the horizontal moving block; set screws are arranged in the threaded holes.

[0009] Further, the horizontal moving block moves horizontally inside the fixed seat, and the moving distance is 0 - 0.7 cm. The vertical moving block moves vertically inside the fixed seat.

[0010] Further, a dovetail groove is formed on the upper surface of the horizontal moving block; a slider is fixedly connected to the lower surface of the vertical moving block, and the slider is slidably connected inside the dovetail groove.

[0011] Further, limiting blocks are fixedly arranged on both sides of the horizontal moving block; chutes are formed at positions of the fixed seat corresponding to the limiting blocks, and the limiting blocks are slidably arranged inside the chutes.

[0012] Further, fixing grooves are formed on both sides of the horizontal moving block; the limiting blocks are fixedly connected inside the fixing grooves through screws.

[0013] Further, retaining grooves are formed at positions of the chutes corresponding to both ends of the limiting blocks, and the retaining grooves are used for the screws fixing the limiting blocks to move inside them.

[0014] Further, three groups of the threaded holes and the setscrews are provided corresponding to both ends of the fixed seat.

[0015] Advantages of the utility model:

[0016] By using the cooperation of the setscrew and the threaded hole, the operator can freely adjust the protruding length of the setscrew. The position of the horizontal moving block inside the fixed seat can be fixed through the setscrew. When the horizontal moving block moves, since the contact surface between the horizontal moving block and the vertical moving block is an inclined plane, the vertical moving block can be forced to move upward inside the fixed seat. Furthermore, the distance between the upper and lower vertical moving blocks in the gear hobbing machine can be adjusted, and thus the purpose of processing different specifications of tooth profiles with the same gear hobbing plate can be achieved to meet different processing requirements.

[0017] The utility model uses the cooperation of the chute and the limiting block to restrict the horizontal moving block, so that the horizontal moving block cannot be taken out from inside the fixed seat. The cooperation of the horizontal moving block and the fixed seat is used to restrict the vertical moving block, and the vertical moving block cannot be taken out because the horizontal moving block cannot be taken out, realizing the assembly of the horizontal moving block and the vertical moving block. After the teeth on the vertical moving block are damaged, the operator can replace them through the quick-release structure without discarding all of them. At the same time, the vertical moving block with different specifications of teeth can be replaced to meet the processing requirements for different workpieces. Description of the drawings
