Description

Technical Field

[0001] The utility model relates to the technical field of aluminum processing, in particular to a clamping table for tapping the oil change holes of a reducer housing. Background Art

[0002] A reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine. It plays a role in matching speeds and transmitting torques between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] During the use of the reducer, in order to play roles such as lubrication, cooling, and cleaning, lubricating oil needs to be added to its interior. After the lubricating oil is used for a period of time, due to the reduction of its various performances and the increase of impurities, it needs to be replaced in time. Therefore, an oil drain hole and an oil injection hole are provided on one side of the bottom shell of the reducer. Generally, the oil drain hole is horizontally arranged, while the oil injection hole is inclined downward. The means to avoid oil leakage is to connect a sealing screw through threads in the hole, which requires tapping the oil injection hole and the oil drain hole. The existing tapping clamping tools cannot quickly switch the angle of the clamped housing, and the threads of the oil injection hole and the oil drain hole need to be processed in multiple processes. Therefore, a clamping table that can quickly switch the clamping angle and facilitate tapping processing is needed. Summary of the Utility Model

[0010] In the erected state, the mounting plate is clamped inside the vertical support seat, so that the clamped machine shell is in a vertical state, which is convenient for the thread processing at the oil drain hole. When the bottom of the mounting plate is clamped inside the inclined support seat, the oil injection hole is in a vertical state, which is convenient for the thread processing inside the oil injection hole.

[0011] In a preferred embodiment of the present utility model, a clamping groove matching the first screw is formed at the top of the vertical support seat, and a clamping groove matching the second screw and the wing nut is formed at the top of the inclined support seat;

[0012] After the first screw is clamped into the clamping groove at the top of the vertical support seat, it is clamped and fixed through the locking knob to ensure that the machine shell is in a vertical state. When the second screw is clamped into the clamping groove at the top of the inclined support seat, the wing nut is tightened to make the machine shell in a fixed state.

[0013] In a preferred embodiment of the present utility model, one end of the guide rod observes and extends outside one side of the clamping seat, and a guide hole matching the guide rod is formed on the surface of the clamping seat;

[0014] The guide rod ensures that when the rotary clamping knob is rotated, the pressing block will not rotate, so as to ensure the pressing effect of the pressing block on the machine shell.

[0015] In a preferred embodiment of the present utility model, a support plate is arranged between the back of the inclined support seat and the base.

[0016] The beneficial effects of the present utility model are:

[0022] The following describes in detail the preferred embodiments of the present utility model with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. The directional terms mentioned in the present utility model, such as "up", "down", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions in the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0023] As Figures 1 - 3 shown, a clamping table for tapping the oil change hole of a reducer housing includes a base 1, a vertical seat 2, an inclined seat 3, a clamping shaft 4, a clamping assembly 5 and a housing 6. The vertical seat 2 and the inclined seat 3 are fixedly arranged on the upper surface of the base 1. The clamping shaft 4 is arranged inside the bottom of the inclined seat 3. The clamping assembly 5 is arranged between the vertical seat 2 and the inclined seat 3. The housing 6 is clamped inside the clamping assembly 5. The clamping assembly 5 includes a mounting plate 51, a clamping seat 52, a compression knob 53, a compression block 54, a guide rod 55, a limit seat 56, a first screw 57, a locking knob 58, a second screw 59 and a wing nut 510. The clamping seat 52 is fixedly arranged on the outside of the mounting plate 51. The compression knob 53 is threadedly connected to the clamping seat 52. The compression block 54 is movably connected to the end of the compression knob 53. The guide rod 55 is fixedly arranged on the back of the compression block 54. The limit seat 56 is fixedly arranged on the outside of the mounting plate 51. The first screw 57 is fixedly arranged on the outside of the bottom of the mounting plate 51. The locking knob 58 is threadedly connected to the first screw 57. The second screw 59 is fixedly arranged on the back of the mounting plate 51. The wing nut 510 is threadedly connected to the second screw 59.

[0024] Specifically, the casing 6 is clamped within the clamping seat 52, the pressing block 54 is clamped outside the casing 6, the bottom of the casing 6 contacts the top of the limit seat 56, the limit seat 56 is located outside the bottom of the clamping seat 52, the bottom of the mounting plate 51 is sleeved outside the clamping shaft 4, the vertical support seat 2 and the inner side of the inclined support seat 3 are provided with clamping grooves matching the width of the mounting plate 51, the top of the vertical support seat 2 is provided with a clamping groove matching the first screw rod 57, and the top of the inclined support seat 3 is provided with clamping grooves matching the second screw rod 59 and the wing nut 510. One end of the guide rod 55 observes and extends outside one side of the clamping seat 52, and the surface of the clamping seat 52 is provided with a guide hole matching the guide rod 55. A support plate is arranged between the back of the inclined support seat 3 and the base 1.

Then, turn one end of the oil drain hole and the oil filling hole of the casing 6 upward, and clamp the casing 6 between the mounting plate 51 and the pressing block 54. The bottom of the casing 6 will contact the top of the limit seat 56. Since there are reinforcing rib plates during the casting of the bottom of the casing 6, and the top of the limit seat 56 is provided with a clamping groove matching it, the installation position of the casing 6 can be limited to a certain extent. Then, tighten the pressing knob 53 to fix the casing 6 by the pressing block 54.

Flip the mounting plate 51 so that its bottom rotates around the clamping shaft 4 until the outside of the bottom of the mounting plate 51 is clamped in the inner clamping groove of the vertical support seat 2, and tighten the locking knob 58 on the surface of the first screw rod 57 to vertically fix the fixed casing 6, which is convenient for tapping the oil drain hole. After the processing is completed, loosen the locking knob 58 and make the mounting plate 51 tilt downward until its bottom is clamped in the inner clamping groove of the inclined support seat 3. At this time, the second screw rod 59 and the wing nut 510 on the back of the mounting plate 51 are inserted into the back of the inclined support seat 3 from the top clamping groove of the inclined support seat 3, and rotate the wing nut 510 to lock the mounting plate 51. At this time, the oil filling hole is vertically arranged, which is convenient for the threading processing work in the oil filling hole.
