[0002] In the field of machining, fixtures are crucial process equipment used to hold and position workpieces, ensuring their correct position during machining. They play a key role in guaranteeing machining accuracy, improving production efficiency, and reducing labor intensity. In the drilling of bearing housings, traditional fixtures typically employ a fixed installation method, providing only simple clamping and fixation of the bearing housing. This type of fixture has significant drawbacks. When drilling multiple screw holes on the end face of the bearing housing, the operator needs to constantly manually move the bearing housing or the entire fixture to adjust its position. This not only involves a huge workload but also frequently causes positioning deviations in the bearing housing, affecting drilling accuracy and reducing product quality. Simultaneously, the high-load operation increases operator fatigue and reduces comfort, further impacting work efficiency and failing to meet the high-efficiency and precise production demands of modern machining. Therefore, there is an urgent need for a bearing housing drilling fixture that can flexibly adjust its position, improving machining convenience and accuracy. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a bearing housing drilling fixture, which can reduce the workload of operators and improve work comfort and efficiency.

[0023] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Depend on Figure 1-5The bearing housing drilling fixture shown includes a vise 2 for clamping the bearing housing 1 and a translation fixture. The translation fixture includes a table 3, the top surface of which is screwed to the vise 2. A transmission assembly is fixedly connected to one end of the bottom surface of the table 3. A base plate 4 is slidably contacted to the bottom surface of the transmission assembly. A guide plate 5 is fixedly connected to one end of the top surface of the base plate 4, and a mounting plate 6 is fixedly connected to the other end of the top surface of the base plate 4. The guide plate 5 and the mounting plate 6 are arranged opposite each other. The guide plate 5 is slidably connected to the transmission assembly. A drive assembly is detachably connected to the transmission assembly. A support column 7 is fixedly connected to the center of the base plate 4. The top surface of the support column 7 is slidably in contact with the table 3. A groove 20 is formed on the bottom surface of the table 3. The groove 20 is parallel to the rack 9. A drive block 21 is provided at the bottom end of the table 3. The groove 20 is slidably in contact with the top end of the drive block 21. Furthermore, the supporting surface area of ​​the top surface of the drive block 21 is more than three times the area of ​​the bottom surface, which improves the supporting stability of the table 3. The bottom surface of the drive block 21 is in sliding contact with the base plate 4; one end of the drive assembly is rotatably connected to the support column 7, and the drive assembly is screwed to the drive block 21.

[0025] Further optimizing the design, the transmission component includes a bracket 8. The bottom end of the bracket 8 slides in contact with the top surface of the base plate 4. Two feet are provided at both ends of the bracket 8, and racks 9 are fixedly connected between the two feet. A gear 10 meshes with the rack 9. A rotating shaft 11 is fixedly connected to the center of the gear 10. A fixing block is rotatably connected to one end of the rotating shaft 11, and the fixing block is fixedly connected to the top surface of the guide plate 5. Several equally spaced insertion holes 12 are provided on the end face of the gear 10. The gear 10 is detachably connected to the drive component through the insertion holes 12. The drive component and the gear 10 are connected to the insertion rod 17 through the insertion holes 12, enabling the drive component to drive the gear 10, which in turn drives the rack 9. The rack 9 drives the bracket 8, ultimately achieving horizontal position adjustment of the platform 3 in one direction.

[0026] Further optimizing the design, the drive assembly includes a connector. A drive shaft 13 is fixedly connected to the center of one end of the connector. Several teeth 14 are fixedly connected at equal intervals to the outer side of the drive shaft 13 near the connector. A screw cylinder 15 is sleeved on and rotatably connected to the outer side of the drive shaft 13. One end of the screw cylinder 15 passes through a support column 7 and is rotatably connected to it. The screw cylinder 15 passes through a drive block 21 and is screwed to it. One end of the drive shaft 13 is slidably connected to the mounting plate 6. Several grooves are formed on the inner wall of the screw cylinder 15. The teeth 14 correspond one-to-one with the grooves and are detachably inserted. By inserting the teeth 14 into the grooves, rotating the drive shaft 13 drives the screw cylinder 15 to rotate. The rotation of the screw cylinder 15 drives the drive block 21 to move horizontally and longitudinally. The sliding fit between the top of the drive block 21 and the sliding groove 20 enables the horizontal and longitudinal movement of the drive platform 3, thereby adjusting the horizontal position of the vise 2 in another direction.

[0027] Furthermore, the number of teeth 14 and holes 12 is preferably greater than 4. Increasing the number of teeth 14 and holes 12 can improve the insertion efficiency of the rod 17 and the holes 12, and the teeth 14 and the slots.

[0028] A further optimized design includes a connecting block 16. One side of the connecting block 16 is fixedly connected to the other end of the drive shaft 13. A plurality of insert rods 17 are fixedly connected at equal intervals on the side of the connecting block 16 away from the drive shaft 13. Each insert rod 17 corresponds to a corresponding insertion hole 12, and the insert rods 17 are inserted into the insertion holes 12. The length of the teeth 14 is less than the distance from the end face of the screw barrel 15 to the end face of the insert rod 17. The connection between the insert rods 17 and the insertion holes 12 enables the power connection between the drive assembly and the gear 10. By disengaging the insert rods 17 from the insertion holes 12 and simultaneously sliding the teeth 14 into the grooves, the power connection between the drive assembly and the gear 10 can be interrupted, while the power connection with the screw barrel 15 can be established.

[0029] In a further optimized design, a dial 18 is fixedly connected to one end of the drive shaft 13, and a crank handle 19 is rotatably connected to the end face edge of the dial 18. The dial 18 increases the rotational torque of the drive shaft 13, reducing the workload of operating this fixture.

[0030] The working process of this embodiment is as follows:

[0031] When using this bearing housing drilling fixture, first place the bearing housing 1 in the vise 2 and clamp it. The vise 2 is used to ensure the stability of the bearing housing 1 during the machining process. The vise 2 is fixedly mounted on the table 3, and a transmission component is connected to one end of the bottom surface of the table 3.

[0032] When it is necessary to adjust the horizontal position of the vise 2, insert the drive assembly rod 17 into the gear 10's insertion hole 12, and rotate the crank handle 19 to drive the dial 18, thereby causing the drive shaft 13 to rotate. The rod 17 on the drive shaft 13 drives the gear 10 to rotate, and the gear 10 meshes with the rack 9, driving the rack 9 to move the support 8, thereby realizing the horizontal movement of the bench plate 3 and the vise 2 fixed on it.

[0033] To adjust the horizontal and longitudinal position of the vise 2, pull the insert rod 17 out of the insertion hole 12, so that the pawl 14 engages with the groove on the inner wall of the screw barrel 15. Turn the crank handle 19 to drive the drive shaft 13, which in turn drives the screw barrel 15 to rotate through the engagement of the pawl 14 and the groove. Since the screw barrel 15 is screwed to the drive block 21, when the screw barrel 15 rotates, it drives the drive block 21 to move horizontally and longitudinally on the base plate 4. The top of the drive block 21 slides and adapts to the sliding groove 20 of the table plate 3, thereby driving the table plate 3 and the vise 2 to move horizontally and longitudinally.

[0034] A support column 7 is fixedly connected to the center of the base plate 4. The top surface of the support column 7 slides in contact with the bottom surface of the table plate 3, providing support for the movement of the table plate 3. A guide plate 5 is fixedly connected to one end of the top surface of the base plate 4, and a mounting plate 6 is fixedly connected to the other end. The guide plate 5 is slidably connected to the bracket 8 in the transmission assembly. Through the above operations, the vise 2 can be moved freely within a certain range on the horizontal plane, facilitating the drilling of several screw holes on the end face of the bearing seat 1, reducing the workload of the operator, and improving work comfort and efficiency.

[0035] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
