Description

Technical Field

[0001] This utility model belongs to the field of aerospace shaft parts processing technology, and specifically relates to a clamping device for processing aerospace shaft parts. Background Technology

[0002] Machining shaft-type aerospace components is one of the core technologies in the aerospace manufacturing field. These components are typically used in critical parts such as rocket engines, satellite attitude control systems, and spacecraft transmission mechanisms, and have extremely stringent requirements for precision, reliability, lightweight design, and resistance to extreme environments.

[0003] Existing clamping devices for machining shaft-type aerospace parts use a combination of a tapered sleeve and an elastic sleeve, with hydraulic / pneumatic drive for radial contraction clamping to clamp and fix the shaft-type aerospace parts for subsequent machining. However, in actual use, the high concentricity and repeatability accuracy required for clamping and fixing shaft-type aerospace parts means that it takes a considerable amount of time for machining personnel to install and position different models and specifications of shaft-type aerospace parts to ensure they are clamped and fixed in the appropriate position, making them rather cumbersome to use. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a clamping device for processing shaft-type aerospace parts. By adjusting the horizontal position and height of clamping roller two and the vertical position of clamping roller one, clamping roller two and clamping roller one can quickly and stably clamp and fix shaft-type aerospace parts at appropriate positions and angles.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a clamping device for processing shaft-type aerospace parts, including a worktable, a clamping platform is provided in the middle of the upper surface of the worktable, multiple slide rails are provided on the upper surface of the worktable, and sliding seats are slidably arranged between adjacent slide rails. Each sliding seat has a U-shaped seat II provided on its upper side through an adjustment mechanism. A clamping roller II is rotatably arranged inside the U-shaped seat II. The adjustment mechanism is used to adjust the clamping position of the clamping roller II. Multiple support legs are provided on the lower surface of the worktable, and rubber pads are glued and fixed to the lower surface of each support leg.

[0006] As a further improvement of this utility model, the adjusting mechanism includes a rotating seat fixedly mounted on the upper surface of each sliding seat. Each rotating seat has symmetrically distributed rotating frames rotatably mounted on a rotating shaft. A sliding cylinder is fixedly mounted on the upper side of each rotating frame, and a sliding arm is slidably mounted on the upper side of each sliding cylinder. A U-shaped seat is fixedly mounted on the top of the sliding arm. An electric push rod is provided at the bottom of the inner side of each sliding cylinder. The telescopic end of the electric push rod is connected and fixed to the adjacent sliding arm. A worm gear is fixedly mounted on the outer arc surface of each rotating shaft. A worm is rotatably mounted inside each rotating seat. The worms are meshed with the adjacent worm gears. A dual-axis motor is provided in the middle of each rotating seat. The output shaft of the dual-axis motor is fixed to the adjacent worms through a coupling.

[0007] As a further improvement of this utility model, a lifting seat is slidably provided on the upper side of the clamping table, and a U-shaped seat is fixedly provided on the upper side of the lifting seat. A clamping roller is symmetrically distributed inside the U-shaped seat. An electric push rod is provided inside the clamping table, and the telescopic end of the electric push rod is connected and fixed to the lifting seat.

[0008] As a further improvement of this utility model, the upper surface of the workbench is provided with symmetrically distributed electric push rods three, and the telescopic ends of the electric push rods three are respectively connected and fixed to the adjacent sliding seats.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] First, the shaft-type aerospace parts to be processed are placed between clamping rollers one. Then, by controlling the operation of electric push rod three, the rotating seat drives clamping roller two to move horizontally, thereby adjusting the horizontal position of clamping roller two.

[0011] Secondly, the sliding arm connected to the electric push rod moves through the telescopic end, causing the sliding arm to slide between the sliding arm and the sliding cylinder. This causes the sliding arm to move the clamping roller 2 up or down, adjusting the vertical position of the clamping roller 2 and thus adjusting the clamping position of the clamping roller 2.

[0012] Third, control the operation of the dual-axis motor so that the output shaft of the dual-axis motor drives the worm gear connected to it to rotate. Then, through the meshing relationship between the worm gears, the rotating shaft where the worm gear is located is driven to rotate, causing the clamping roller two to rotate around the rotating shaft towards the side closer to the shaft-type aerospace parts, so as to quickly and stably clamp and fix the shaft-type aerospace parts.

[0013] Fourth, by adjusting the horizontal position and height of clamping roller two and the vertical position of clamping roller one, clamping roller two and clamping roller one can quickly and stably clamp and fix shaft-type aerospace parts at appropriate positions and angles.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the device includes a worktable 101, a clamping platform 103 is provided in the middle of the upper surface of the worktable 101, and multiple slide rails 201 are provided on the upper surface of the worktable 101. Sliding seats 202 are slidably arranged between adjacent slide rails 201. Each sliding seat 202 has a U-shaped seat 207 on its upper side through an adjustment mechanism. A clamping roller 208 is rotatably arranged inside the U-shaped seat 207. The adjustment mechanism is used to adjust the clamping position of the clamping roller 208.

[0022] like Figure 3 , 4As shown, the adjustment mechanism includes a rotating seat 203 fixedly mounted on the upper surface of each sliding seat 202. Each rotating seat 203 is rotatably mounted with symmetrically distributed rotating frames 204 via a rotating shaft. A sliding cylinder 205 is fixedly mounted on the upper side of each rotating frame 204, and a sliding arm 206 is slidably mounted on the upper side of each sliding cylinder 205. A U-shaped seat 207 is fixedly mounted on the top of the sliding arm 206. An electric push rod is provided at the bottom of the inner side of each sliding cylinder 205, and the telescopic end of the electric push rod is connected and fixed to the adjacent sliding arm 206. A worm gear 209 is fixedly sleeved on the outer arc surface of each rotating shaft. A worm 210 is rotatably mounted inside each rotating seat 203, and the worm 210 is meshed with the adjacent worm gear 209. A dual-axis motor 211 is provided in the middle of each rotating seat 203, and the output shaft of the dual-axis motor 211 is fixed to the adjacent worm 210 via a coupling.

[0023] like Figure 1 , 2 As shown, a lifting seat 104 is slidably arranged on the upper side of the clamping table 103, and a U-shaped seat 105 is fixedly arranged on the upper side of the lifting seat 104. A clamping roller 106 is symmetrically distributed inside the U-shaped seat 105. An electric push rod 2 is arranged inside the clamping table 103, and the telescopic end of the electric push rod 2 is connected and fixed to the lifting seat 104.

[0024] like Figure 1 , 2 As shown, the upper surface of the worktable 101 is provided with symmetrically distributed electric push rods three, and the telescopic ends of the electric push rods three are respectively connected and fixed to the adjacent sliding seats 202.

[0025] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the lower surface of the workbench 101 is provided with multiple legs 102, and the lower surface of each leg 102 is glued and fixed with a rubber pad.

[0026] In use, the shaft-type aerospace parts to be processed are placed between the clamping rollers 106. Then, by controlling the operation of the electric push rod 3, the telescopic end of the electric push rod 3 drives the sliding seat 202 connected to it to slide between the slide rails 201. This causes the rotating seats 203 on both sides to move towards each other or away from each other, so that the rotating seats 203 drive the clamping roller 208 to move horizontally, thereby adjusting the horizontal position of the clamping roller 208.

[0027] Then, the extension end of the electric push rod 2 drives the lifting seat 104 to slide between the clamping table 103, so that the lifting seat 104 drives the clamping roller 106 and the shaft-type aerospace parts placed between the clamping roller 106 to rise or fall, thereby adjusting the height at which the shaft-type aerospace parts are clamped and fixed.

[0028] The sliding arm 206 connected to the electric push rod 1 is moved by the telescopic end of the electric push rod 206, which in turn causes the sliding arm 206 to slide with the sliding cylinder 205. This causes the sliding arm 206 to drive the clamping roller 208 to rise or fall, thereby adjusting the vertical position of the clamping roller 208 and thus adjusting the clamping position of the clamping roller 208.

[0029] Then, the dual-axis motor 211 is controlled to run, so that the output shaft of the dual-axis motor 211 drives the worm gear 210 connected to it to rotate. Then, through the meshing relationship between the worm gears 210, the rotating shaft where the worm gear 210 is located is driven to rotate, so that the rotating shaft drives the rotating frame 204 to rotate, so that the rotating frame 204 rotates towards the vertical center of the worktable 101, and drives the clamping roller 208 to rotate around the rotating shaft towards the side closer to the shaft-type aerospace parts, so as to quickly and stably clamp and fix the shaft-type aerospace parts.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
