Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixtures, and more specifically to a bearing cover plate boring and tapping fixture. Background Technology
[0002] As attached Figure 4 The bearing cover plate shown needs to be bored and tapped during machining. In order to ensure the quality of the bearing cover plate, it needs to be fixed during boring and tapping. However, the existing fixtures cannot quickly clamp and fix it. Therefore, a boring and tapping fixture that can quickly clamp and fix the bearing cover plate is needed. Utility Model Content
[0003] This utility model provides a bearing cover plate boring and tapping fixture, which can quickly clamp and fix the bearing cover plate.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A bearing cover plate boring and tapping fixture includes a fixing plate on the upper end face for placing the bearing cover plate. Two pressure plate seats are symmetrically arranged on the fixing plate, and a pressure plate is rotatably mounted on each of the two pressure plate seats. A pressure block is provided on each of the two pressure plates near the end of the bearing cover plate.
[0005] The lower end of the pressure block is arc-shaped.
[0006] It also includes a base plate, on which multiple support columns are fixed. A fixing plate is fixed above the multiple support columns. Two thin cylinders I are installed on the fixing plate. The two thin cylinders I are equipped with push rods. The two push rods can respectively press the outer end of the pressure plate.
[0007] A torsion spring is provided between the pressure plate and the pressure plate seat to make the pressure plate press against the top rod.
[0008] The upper end of the top rod has a semi-circular structure.
[0009] The fixing plate is provided with multiple stop pins to limit the bearing cover plate in the circumferential direction.
[0010] It also includes a stop pin fixing plate, which slides on multiple support columns, and the lower ends of multiple stop pins are fixed on the stop pin fixing plate.
[0011] A thin cylinder II is provided between the stop pin fixing plate and the base plate.
[0012] A gasket is fitted onto the stop pin.
[0013] The upper ends of all the retaining pins are rounded.
[0014] The beneficial effects of this utility model are as follows: By rotating two pressure plates on two pressure plate seats, the two pressure blocks can quickly clamp and fix the bearing cover plate to the fixed plate, thereby achieving rapid clamping and fixing of the bearing cover plate; by controlling multiple stop pins to slide out from the pressure plates, the periphery of the bearing cover plate is blocked, forming a circumferential limit on the bearing cover plate, further improving the stability of the bearing cover plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] The following is combined with Figure 1-4 A detailed description of a boring and tapping fixture for bearing cover plates is provided: A bearing cover plate boring and tapping fixture includes a fixing plate 5 on the upper end face for placing the bearing cover plate. Two pressure plate seats 7 are symmetrically arranged on the fixing plate 5. Pressure plates 8 are rotatably mounted on both pressure plate seats 7. Pressure blocks 9 are provided on both pressure plates 8 near the end of the bearing cover plate.
[0019] When in use, place the bearing cover plate flat on the fixed plate 5 between the two pressure plate seats 7, and then push the outer ends of the two pressure plates 8 upward to make the pressure plates 8 rotate on the pressure plate seats 7, thereby making the pressure block 9 press on the bearing cover plate, thus quickly clamping the bearing cover plate on the fixed plate 5. A horizontal shaft runs through the pressure plate base 7 and the pressure plate 8, enabling the pressure plate 8 to rotate on the pressure plate base 7.
[0020] Further: By making the lower end of the pressure block 9 arc-shaped, the arc surface contacts the bearing cover plate, thus preventing damage to the surface of the bearing cover plate when the pressure block 9 descends to clamp the bearing cover plate.
[0021] Further: It also includes a base plate 1, on which multiple support columns 2 are fixed. A fixing plate 5 is fixed above the multiple support columns 2. Two thin cylinders I10 are installed on the fixing plate 5. The two thin cylinders I10 are equipped with push rods 6. The two push rods 6 can respectively press against the outer end of the pressure plate 8.
[0022] The base plate 1 supports the fixed plate 5 through multiple support columns 2. At the same time, it is used to install two thin cylinders I10. When the two thin cylinders I10 are extended and push the two push rods 6 to rise, the two push rods 6 will contact the outer ends of the two pressure plates 8, and then push the outer ends of the two pressure plates 8 to rotate upward, thereby realizing the automatic and rapid clamping and fixing of the bearing cover plate.
[0023] Further: By providing a torsion spring between the pressure plate 8 and the pressure plate seat 7, the pressure plate 8 can rotate automatically on the pressure plate seat 7, thereby driving the pressure block 9 to rise and causing the outer end of the pressure plate 8 to automatically descend and press against the top rod 6. As a result, when the two thin cylinders I10 retract, the two pressure blocks 9 can automatically separate from the bearing cover plate, making it easier to remove the bearing cover plate and replace it with a new bearing cover plate to be processed, thus improving processing efficiency.
[0024] Further: The upper end of the push rod 6 is a semi-circular structure, which allows the upper semi-circular surface of the push rod 6 to contact the pressure plate 8. As the pressure plate 8 rotates, the contact and sliding between the push rod 6 and the pressure plate 8 becomes smoother.
[0025] Further: Multiple stop pins 11 are provided through the fixed plate 5 to limit the bearing cover plate in the circumferential direction.
[0026] It also includes a stop pin fixing plate 3, which slides on multiple support columns 2, and the lower ends of multiple stop pins 11 are all fixed on the stop pin fixing plate 3.
[0027] A thin cylinder II 12 is provided between the stop pin fixing plate 3 and the base plate 1.
[0028] After the bearing cover is placed on the fixed plate 5, the thin cylinder II 12 is extended, thereby pushing the stop pin fixing plate 3 to slide upward on multiple support columns 2, and then driving multiple stop pins 11 to slide out from the fixed plate 5, thereby limiting the periphery of the bearing cover, achieving the purpose of circumferentially limiting the bearing cover and further improving the stability of the bearing cover. When replacing the bearing cover, the thin cylinder II12 is retracted to retract the stop pin 11 into the fixed plate 5, thereby restoring the upper surface of the fixed plate 3 to a flat state, making it easier to place the bearing cover on the fixed plate 3. It should be noted that the fixing plate 3 has three hollow holes corresponding to the boring and tapping of the bearing cover plate, which ensures the smooth boring and tapping. At the same time, when placing the bearing cover plate, the bearing cover plate can be initially aligned with the three hollow holes, and then the stop pin 11 is extended to achieve precise positioning of the bearing cover plate. Furthermore, the upper end of the stop pin 11 is set with a round head structure, so that when the stop pin 11 rises and lifts the edge of the bearing cover plate, the bearing cover plate can automatically slide down for automatic alignment.
[0029] Further: By fitting a shim 4 onto the stop pin 11, a gap can be formed between the stop pin fixing plate 3 and the fixing plate 5, preventing the stop pin fixing plate 3 and the fixing plate 5 from being completely fitted together, while adjusting the extension height of the stop pin 11.
[0030] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
