Description

Technical Field

[0001] The utility model relates to the field of automobile differentials, in particular to automobile differential housing processing equipment. Background Art

[0002] The automobile differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. In order to facilitate the distribution of various components inside the automobile differential housing, it is necessary to ensure that the inner wall of the automobile differential housing has the actual required shape. In order to facilitate the processing of the automobile differential housing, the automobile differential housing is divided into two and set into a combined structure. In this case, no matter which part of the automobile differential housing is in a semi-open state, the interior can be directly exposed to the outside world. However, since there are output holes at both ends of the automobile differential, the diameter of the output hole is much smaller than the internal space of the automobile differential housing. Therefore, if the processing tool is axially through If the output hole is not passed, it is difficult to process the inner wall of the automobile differential housing. If special-shaped tools are used, special-shaped tools with larger width angles cannot pass through the output hole at all. Therefore, it is necessary to set processing devices with multiple angles on the processing equipment, so that multiple tools are distributed in multiple positions in the three-dimensional space. However, this processing method will cause the processing equipment to become extremely complicated, and the more parts, the greater the error rate of the processing equipment, and the cost of use will be seriously increased. At the same time, when the processing equipment is installed with multiple processing devices, the size of the processing equipment will become larger, which is not only not conducive to transportation, but also takes up a lot of space when it is actually used.

[0028] The tool holder 701 is provided with a thickened seat 713 that fits against the outer wall of the tool holder turntable 708; the thickened seat 713 and the tool holder turntable 708 are fixed by a number of evenly distributed screws.

[0029] A waste trough 10 is provided on the front right side of the upper surface of the fuselage 1 ; the width of the upper slot of the waste trough 10 gradually decreases downward; a cleaning port 12 is provided on the right side wall of the fuselage 1 that is connected to the bottom of the waste trough 10 .

[0030] The inclination angles of the inclined surface 5 and the inclined slide plate 601 are both 30 degrees.

[0031] The method of using the utility model is as follows:

[0032] When the spindle fixture 3 clamps the automobile differential housing 11 , the tool mounted on the tool holder 701 can be driven to shift. At this time, the tool is located on the right side of the spindle fixture 3 .

[0033] When the tool needs to be shifted, the first motor 805, the second motor 607 and the rotating motor 706 can be started. When the first motor 805 is started, the motor shaft of the first motor 805 will drive the first screw rod 803 to rotate. Since the first slider 807 on the lower surface of the sliding plate 806 matches the first slide rail 801, the first slide rail 801 can play a role in limiting guidance. When the first screw rod 803 is threadedly connected to the first screw seat provided at the center of the lower surface of the sliding plate 806, when the first screw rod 803 rotates, the sliding plate 806 can convert the rotational force into its own translational force. At this time, the sliding plate 806 follows the trajectory of the first slide rail 801 to the left and approaches the automobile differential housing 11 of the spindle clamp 3.

[0034] When the second motor 607 is started, the motor shaft of the second motor 607 will drive the second screw rod 605 to rotate. At this time, the second slider 608 on the lower surface of the inclined slide 601 matches the second slide rail 603, and the second slide rail 603 can limit and guide the inclined slide 601. Since the second screw seat in the center of the lower surface of the inclined slide 601 is threadedly connected to the second screw rod 605, when the second screw rod 605 rotates, the inclined slide 601 will convert the rotational force into a force that moves along the trajectory of the second slide rail 603, thereby facilitating the tool holder turntable 708 to move forward and downward through the inclined slide 601.

[0035] When the rotary motor 706 is started, the motor shaft of the rotary motor 706 drives the driving gear 707 to rotate, and the driving gear 707 is meshed with the toothed disc 710 through the driven gear 712. Therefore, when the driving gear 707 rotates, the driven gear 712 and the toothed disc 710 rotate synchronously, thereby realizing the rotation of the tool holder turntable 708. When the tool holder turntable 708 rotates, the tool holder 701 drives the tool 702 to rotate synchronously. As the tool 702 moves to the actual required position on the left and right moving device and the front and back moving device, the rotating tool holder 701 can The special-shaped tool used to process the inner wall of the automobile differential housing 11 can be rotated into the automobile differential housing 11. At this time, the thinner handle of the tool 702 is in the output hole 1101 of the automobile differential housing 11, and the wider processing end of the tool 702 is located inside the automobile differential housing 11. After the processing of one inner wall is completed, the handle of the tool 702 can be moved left and right in the output hole 1101 through the left and right moving device, thereby moving the processing end of the tool 702, so that the tool 702 can process the inner wall of different positions of the automobile differential housing 11.

[0036] From the above, it can be seen that the utility model can make the rotating device in an inclined state through the inclined surface 5. When the rotating device is tilted, the tool can be moved into the automobile differential housing by moving left and right, moving forward and backward along the inclination angle of the inclined surface, and rotating, effectively avoiding the limitation of the output hole 1101 of the automobile differential housing 11, and the tool holder 701 is circumferentially arranged on the tool holder turntable 708 of the rotating device, and a large number of tools 702 are integrated on the tool holder turntable 708, so there is no need to set up a special processing device for installing different tools on the fuselage 1, effectively simplifying the overall structure and reducing the cost of use. As the number of parts is reduced, the error rate of the equipment is reduced accordingly. At the same time, the volume of the equipment can be effectively reduced and the space occupied by the equipment can be reduced. This tool shifting method can more effectively ensure the tool shifting efficiency and the processing efficiency.

[0037] The first shaft seat 802 is provided with a first shaft hole 808 coaxial with the first screw rod 803, and the first shaft hole 808 is provided with a first bearing 809 matching the first screw rod 803. The existence of the first bearing 809 can effectively ensure the smooth rotation of the first screw rod 803, thereby ensuring the smooth movement of the sliding plate 806 along the trajectory of the first slide rail 801.

[0038] The second shaft seat 604 is provided with a second shaft hole 609 coaxial with the second screw rod 605, and the second shaft hole 609 is provided with a second bearing 610 matching the second screw rod 605. The existence of the second bearing 610 can effectively ensure the smooth rotation of the second screw rod 605, thereby ensuring the smoothness of the inclined slide 601 when it tilts and moves along the trajectory of the second slide rail 603.

[0039] There is a protective cover 9 on the upper end of the tool holder turntable 708. The existence of the protective cover 9 can effectively protect the driving gear 707, the driven gear 712 and the gear plate 710, and prevent external dust or debris from entering between the three and causing jamming. The protective cover 9 and the tool holder turntable 708 can be fixed by screws.

[0040] The tool holder 701 is provided with a thickened seat 713 that fits with the outer wall of the tool holder turntable 708. The existence of the thickened seat 713 can effectively improve the rigidity of the tool holder 701, which is more conducive to the processing of the tool 702. The thickened seat 713 and the tool holder turntable 708 are fixed by a number of evenly distributed screws. This fixing method facilitates the disassembly and assembly between the tool holder 701 and the tool holder turntable 708. Corresponding holes 714 can be set at the installation position of the tool holder 701 on the outer wall of the tool holder turntable 708, so as to facilitate the setting of corresponding transmission mechanisms such as gear sets in the tool holder turntable 708, and transmit force to the tool 702 on the tool holder 701, thereby realizing the driving of the tool 702. This tool driving method belongs to the existing driving method and the structure is very easy to set.

[0041] A waste trough 10 is provided on the front right side of the upper surface of the fuselage 1, and the width of the upper slot of the waste trough 10 gradually decreases downward. A cleaning port 12 is provided on the right side wall of the fuselage 1, which is connected to the bottom of the waste trough 10. This structural design facilitates the rapid collection and processing of waste processed by the tool 702 from the automobile differential housing 11.

[0042] The inclined surface 5 and the inclined plate 601 both have an inclination angle of 30 degrees. Under this inclination angle, the tool 702 can accurately enter the automobile differential housing 11 for processing.
