Description

Technical Field

[0001] The utility model relates to the technical field of gear punching devices, in particular to a punching device for gear blank processing. Background Technique

[0002] Gears are the most commonly used mechanical transmission parts, and gears are used in almost any mechanical equipment. The center holes of most existing gears are round holes. When punching gears, the punching operation that does not require positioning is generally carried out before tooth cutting, and the punching groove that requires positioning is generally carried out after tooth cutting. This makes it necessary to determine the tooth gap position when punching the disk gear blank. Currently, when determining the tooth gap position, it is generally only marked with a marker pen, and the corresponding position of the marker pen is clamped during punching. This makes it impossible to effectively determine the clamping position, and during punching, the gear blank may shift under external force, affecting the accuracy of the subsequent punching position. For this reason, we propose a punching device for gear blank processing. Content of the Utility Model

A connecting rod that can move in all directions is arranged on the side of the movable rod away from the detection block. A clamping block that can rotate is arranged on the side of the connecting rod.

[0006] Preferably, the clamping component includes a clamping disk arranged on the side of the main frame, and a "T"-shaped frame is sleeved and installed on the side of the main frame and is rotatably connected to the clamping disk. Three clamping blocks are arranged on the upper side of the clamping disk, and the three clamping blocks are fixedly installed on the side position of the clamping disk through screws. The clamping blocks are "L"-shaped blocks, and one side of the clamping block is arc-shaped.

[0007] Preferably, the detection device includes a mounting groove formed on the side surface of the clamping block. The movable block is movably installed inside the mounting groove and can slide inside the mounting groove. An activity groove is formed on the side surface of the movable block. The activity rod is movably installed inside the activity groove. The warning module is fixedly installed on the side surface of the activity rod. The detection block is fixedly installed on the inner wall of the activity groove. The support cylinder is fixedly connected between the side surfaces of the activity rod and the detection block.

[0008] Preferably, the activity groove is a cylindrical groove with a cross-shaped cross-section, the activity rod is a cylindrical rod with a cross-shaped cross-section, and the support cylinder is a cylindrical tube made of spring steel with a continuous "W" - shaped cross-section.

[0009] Preferably, the detection device further includes restraint grooves formed on both sides of the inner wall of the mounting groove. A restraint block is movably installed inside the restraint grooves. A first screw is provided on the upper side of the clamping block. The clamping block is arranged at a position corresponding to the mounting groove on the side surface of the movable block.

[0010] Preferably, the detection device further includes a connection groove formed on the side surface of the clamping block. The connecting rod is movably installed inside the connection groove. A second screw is provided on the side surface of the clamping block. Connecting blocks are respectively and staggeredly fixedly installed on the side surfaces of the connecting rod and the activity rod close to each other. A restraint rod is arranged between the connecting blocks. A limit block is fixedly sleeved on the side surface of the restraint rod.

[0012] The utility model provides a drilling device for gear blank processing, which has the following beneficial effects:

[0013] (1) For the drilling device for gear blank processing, by setting up a detection device, the un - toothed disk gear blank is clamped. The support cylinder exerts extrusion on the detection block. The detection block can detect the magnitude of the force and feedback it to an external controller, and set this value as the original data. When the disk gear blank generates displacement vibration, the clamping block will drive the activity rod to slide in the activity groove. When the detection block detects that the pressure change on the side surface of the support cylinder exceeds the preset value, the controller controls the warning light to turn on and alarm through the remote receiver of the warning module. In this way, it can detect the drilling process of the clamped gear blank.

[0014] The disk gear blank for clamping the machined gear is first pre-clamped by moving the clamping block through the clamping disk. The connecting rod rotates inside the connecting groove to adjust the rotation direction of the clamping block. The constraint rod constrains the connecting block to form a universal joint structure, enabling the connecting rod to freely adjust the angle for cooperation. In this way, the clamping block is completely clamped between the tooth gaps to restrict and position the gear blank. When the constraint block slides inside the constraint groove and the supporting cylinder presses against the side of the detection block with a force within an appropriate range, the first screw is tightened to fix the constraint block. The same applies when the disk gear blank generates displacement and vibration. This can not only strengthen the constraint on the gear after positioning but also play a role in detecting during the drilling process of the gear blank, ensuring the accuracy of the drilling of the gear blank and being suitable for use with pure gear blanks and machined gear blanks.

[0029] The working principle of the present invention:

[0030] When in use, hold the un-toothed disc gear blank. Drive the internal gear through the screw of the clamping disc 4 to drive its own slider to move. The slider drives the clamping block 5 to adjust the size for clamping the gear. At the same time, pull the warning module 14 so that the movable rod 13 slides inside the movable groove 12 to squeeze and deform the support cylinder 15. The support cylinder 15 also squeezes the detection block 16 at the same time. The detection block 16 can detect the magnitude of the force and feedback it to the external controller, and set the value at this time as the original data. At this time, the second screw 19 screws and fixes the connecting rod 18, and the first screw 10 screws and fixes the constraint block 9. The fastening block 23 is threadedly squeezed against the side of the connection block 20 to be in a fixed state. In this way, when the drill bit 3 drills holes in the disc gear blank, when the disc gear blank generates displacement vibration, the clamping block 11 will drive the movable rod 13 to slide in the movable groove 12. When the detection block 16 detects that the pressure change on the side of the support cylinder 15 exceeds the preset value, the controller controls the warning light to turn on and alarm through the remote receiver of the warning module 14;

[0031] Hold the toothed disc gear blank. First, move the clamping block 5 through the clamping disc 4 to pre-clamp the disc gear blank. At this time, loosen the second screw 19, the fastening block 23 and the first screw 10. Rotate the connecting rod 18 inside the connecting groove 17 to adjust the rotation direction of the clamping block 11. The constraint rod 21 constrains the connection block 20 to form a universal joint structure, so that the connecting rod 18 can freely adjust the angle to cooperate. In this way, the clamping block 11 is completely clamped between the tooth gaps to constrain and limit the gear blank. At this time, then completely clamp the clamping block 5 through the clamping disc 4. When the support cylinder 15 is squeezed against the side of the detection block 16 with a force within a suitable range by sliding the constraint block 9 inside the constraint groove 8, the first screw 10 screws and fixes the constraint block 9. When drilling holes, the displacement vibration of the disc gear blank is detected as above.
