Description

Technical Field

[0001] The utility model relates to a clamping device for a grinding wheel gear grinding machine, belonging to the technical field of gear grinding machine clamping equipment. Background Art

[0002] A grinding wheel gear grinder is a gear processing machine that uses a grinding wheel as a grinding tool to process cylindrical gears or certain gears (such as helical gears and bevel gears in the transmission assembly of new energy vehicles) and the tooth surface of the tool. During the gear processing process, a grinding wheel gear grinder is needed to grind the gear teeth.

[0003] According to the announcement number CN220347377U, a universal clamping device for a CNC formed grinding wheel gear grinding machine is disclosed, which consists of a jig assembly and a three-jaw self-centering chuck. The jig assembly is used to fix to the machine tool worktable with bolts. Since the three-jaw self-centering chuck is provided, the device can be used for workpieces of various specifications, with strong versatility, and solves the problems of various diameter specifications of parts, poor versatility, long procurement cycle, and high cost. In addition, when clamping the gear, the above-mentioned device needs to rotate the adjustment screw several times, which makes the loading and unloading of the gear inconvenient. At the same time, after the gear is clamped, the bottom surface of the gear conflicts with the device. Therefore, when grinding the gear, it is easy for the grinding wheel in some positions to be inconvenient to grind the gear, resulting in low grinding efficiency of the device. Utility Model Content

[0004] The purpose of the utility model is to provide a clamping device for a grinding wheel gear grinder, which can facilitate the clamping of gears and the grinding of the clamped gear teeth, thereby improving the grinding efficiency of the device and effectively improving the practicability of the device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grinding wheel gear grinding machine clamping device, comprising a fixed seat, a support is fixedly provided on the top of the fixed seat, a slide groove is opened in the upper part of the support, a plurality of through grooves are opened in the annular array at the top of the support and the bottom ends of the through grooves are communicated with the internal space of the slide groove, a plurality of support rods are symmetrically and slidably embedded in the inner wall of the bottom end of the slide groove, the top of the support rods is fixedly connected to a movable seat, a plurality of bottom columns are slidably provided in the annular array at the top of the movable seat, a fixed plate is fixedly provided on the top of the bottom column, a nut is fixedly provided on the fixed plate, an adjusting screw is threadedly rotatably provided in the nut, and a clamping block is rotatably connected to the other end of the adjusting screw.

[0006] As a further optimization, fixing holes are symmetrically opened through the top ends of both sides of the fixing seat.

[0007] As a further optimization, a second chute is opened inside the lower part of the fixed seat. A first motor is fixedly arranged on the inner wall of the bottom end of the second chute. The output end of the first motor is fixedly connected with a first lead screw. A slide plate is sleeved on the first lead screw in a threaded manner. The bottom ends of the support rods all extend into the second chute and are fixedly connected with the top end of the slide plate.

[0008] As a further optimization, the cross sections of the slide plate and the second chute are both rectangular structures. A threaded sleeve matching the first lead screw is fixedly embedded through the slide plate.

[0009] As a further optimization, a plurality of third chutes are annularly and arrayedly opened at the top end of the moving seat. Second lead screws are rotatably arranged in the third chutes. Slide blocks are sleeved on the second lead screws in a threaded manner. The top ends of the slide blocks are fixedly connected with the bottom ends of the adjacent bottom columns. Threaded sleeves matching the second lead screws are fixedly embedded through the slide blocks.

[0010] As a further optimization, a second motor is fixedly embedded in the moving seat. The output end of the second motor is fixedly connected with a first bevel gear. One end of each second lead screw close to the first bevel gear is fixedly connected with a second bevel gear. The second bevel gears are all in gear engagement with the first bevel gear.

[0011] As a further optimization, anti-slip pads are fixedly arranged on the sides of the clamping blocks away from the fixing plate, which can improve the anti-slip performance.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: By arranging the second motor, the moving seat, the adjusting screw rod and the clamping blocks, during use, by rotating the adjusting screw rod, the adjusting screw rod pushes the clamping blocks to move to appropriate positions through nuts.

At the same time, the clamping blocks are all located inside the inner circle of the gear. Then, the second motor drives the first bevel gear to rotate. The first bevel gear drives the second lead screws to rotate through the second bevel gears. The second lead screws will drive the slide blocks to move in the third chutes. The bottom columns can be driven to move away from each other through the slide blocks. Thus, the gear can be squeezed and fixed through the clamping blocks. At this time, the first motor drives the first lead screw to rotate. The first lead screw drives the slide plate to move in the second chute. The slide plate drives the moving seat to move upward through the support rods. Thus, the moving seat drives the bottom column to move upward to an appropriate height. The gear can be supported by the bottom column. At the same time, the teeth of the gear are all located outside the bottom column. Thus, the teeth can be suspended. Furthermore, it is convenient for the grinding wheel to grind the teeth of the gear.

[0022] Fixing holes are symmetrically penetrated through the top ends on both sides of the fixed seat 1. By providing the fixing holes, the device can be fixed at a suitable position using bolts.

[0023] A chute two 11 is provided inside the lower part of the fixed seat 1. A motor one 12 is fixedly provided on the inner wall of the bottom end of the chute two 11. The output end of the motor one 12 is fixedly connected with a lead screw one 13. A slide plate 14 is sleeved on the lead screw one 13 in a threaded manner. The bottom ends of the support rods 4 all extend into the chute two 11 and are fixedly connected with the top end of the slide plate 14.

[0025] Embodiment 2

[0026] The difference between this embodiment and Embodiment 1 is that anti-slip pads are fixedly provided on the sides of the clamping blocks 10 away from the fixing plate 7. By providing the anti-slip pads, the friction between the clamping blocks 10 and the inner wall of the gear ring can be increased.

[0027] Working principle of the utility model: When in use, by rotating the adjusting screw rod 9, the adjusting screw rod 9 drives the clamping block 10 to move to a suitable position through the nut 8. Place the gear on the support 2. At this time, the bottom end of the gear abuts against the top end of the bottom column 6, and at the same time, the clamping blocks 10 are all located inside the inner circle of the gear. Then, drive the bevel gear 19 to rotate through the second motor 18. The bevel gear 19 drives the second lead screw 16 to rotate through the bevel gear 20. The second lead screw 16 will drive the slider 17 to move in the third chute 15. The slider 17 can drive the bottom column 6 to move backward. The bottom column 6 will drive the fixing plate 7 and the clamping block 10 to move. Thus, the gear can be squeezed and fixed by the clamping block 10. At this time, drive the first lead screw 13 to rotate through the first motor 12. The first lead screw 13 drives the sliding plate 14 to move in the second chute 11. The sliding plate 14 will drive the moving seat 5 to move upward through the support rod 4. Thus, the moving seat 5 drives the bottom column 6 to move upward to a suitable height. The bottom column 6 can support the gear, and at the same time, the teeth of the gear are all outside the bottom column 6. Thus, the teeth can be suspended, which is convenient for the grinding wheel to grind the teeth of the gear.
