DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] See also Figures 1 to 6 The embodiment of the present invention provides a special tooling for a drive frame product, which is used for Figure 1 The drive frame 01 shown in the figure, the special tooling includes a base plate 1, a limit plate 2, a thrust cylinder 3, an x-axis positioning shaft 6, a y-axis positioning bolt 8 and a rotary clamping oil cylinder 9, four pairs of limit plates 2 are vertically arranged at the four corners of the top surface of the base plate 1, and each pair of limit plates 2 is open toward the y-axis and z-axis. The thrust cylinder 3 is arranged on the top surface of the base plate 1 through a cylinder bracket 4, and the movable end of the thrust cylinder 3 is connected to a z-axis positioning plate 5, and the z-axis positioning plate 5 moves along the x-axis on the top surface of the limit plate 2. The x-axis positioning shaft 6 is arranged on the top surface of the base plate 1 through a positioning seat 7, and the positioning seat 7 is arranged close to the limit plate 2. A threaded hole is opened on one side of the limit plate 2, and the y-axis positioning bolt 8 is threadedly connected to the threaded hole. The rotary clamping oil cylinder 9 is arranged on the top surface of the base plate 1 through a cylinder base 10, and the cylinder base 10 is arranged close to the limit plate 2.

[0023] The limit plates 2 are used to roughly locate the position of the web 02. The ends of the webs 02 on both sides are placed between the four pairs of limit plates 2. The thrust cylinder 3 is used to push the z-axis positioning plate 5 in or out of the roller plate 04, and the z-axis positioning plate 5 is used to limit the position of the drive frame 01 in the z-axis direction. The x-axis positioning shaft 6 is used to be inserted into the mounting hole 05, and the x-axis positioning shaft 6 is used to limit the position of the drive frame 01 in the x-axis direction. The y-axis positioning bolt 8 is screwed into the threaded hole on the limit plate 2 and presses the web 02 against the inner wall of the limit plate 2, thereby limiting the position of the drive frame 01 in the y-axis direction. The movable end of the rotary clamping cylinder 9 is rotated to the top of the wing plate 03 and pressed downward, thus completing the limit and fixation of the drive frame 01 in the xyz directions, avoiding displacement during processing and ensuring processing accuracy. In addition, using this special tooling, the entire processing process of the drive frame 01 can be completed in a single clamping, without the need for multiple disassembly and adjustment of the position, which is conducive to improving processing efficiency.

[0024] In addition, in another embodiment of the present invention, a limiting groove is provided on the top surface of each pair of limiting plates 2 along the x-axis, and the z-axis positioning plate 5 slides in the limiting groove. The limiting groove is used to limit the movement of the z-axis positioning plate 5 to ensure accuracy. The movable end of the thrust cylinder 3 is threadedly connected to the z-axis positioning plate 5, and the movable end of the thrust cylinder 3 is also threadedly connected to an adjusting nut. The connection length between the movable end of the thrust cylinder 3 and the z-axis positioning plate 5 is adjustable, which is convenient for adjustment according to actual needs. The adjusting nut is used to adjust the relative position of the movable end of the thrust cylinder 3 and the z-axis positioning plate 5 after the adjustment. The base plate 1 is a rectangular structure, and the distance between the two pairs of limiting plates 2 and one side of the base plate 1 is greater than the distance between the other two limiting plates 2 and the other side of the base plate 1. The side of the drive frame 01 with the ear plate is larger in size, and this side is placed on the side with the larger distance between the two pairs of limiting plates 2 and one side of the base plate 1, so that the base plate 1 can better support the drive frame 01. The spacing between each pair of limit plates 2 is greater than the width of the wing plates 03 of the drive frame 01, making it easier to place the web 02 and wing plates 03 of the drive frame 01 between the limit plates 2 by hoisting, thereby improving the efficiency of rough positioning. A plurality of pads 11 are fixedly provided on the top surface of the bottom plate 1 between the two pairs of limit plates 2. The pads 11 are used to temporarily support the drive frame 01, transition to subsequent position adjustments, and act as a buffer. After the drive frame 01 is fixed, the pads 11 do not contact the drive frame 01. The z-axis positioning plate 5 is provided with a vertical through hole 12, which is aligned with the opening on the roller plate 04. The diameter of the through hole 12 is larger than the designed diameter of the opening on the roller plate 04, making room for the drill bit when boring the roller plate 04.

[0025] In summary, when the dedicated tooling for the drive frame product provided by the embodiment of the present invention is in use, the thrust cylinder 3 pulls back the z-axis positioning plate 5 so that the space between the limit plates 2 is unobstructed, the rotary clamping cylinder 9 is rotated to a safe position, and the drive frame 01 to be processed is transported to the top of the tooling by the crane, and the web 02 of the drive frame 01 is aligned with the limit plate 2 and placed in, and the hoisting state is maintained, so that the gap between the roller plates 04 is aligned with the limit groove on the limit plate 2, and the thrust cylinder 3 is controlled to push the z-axis positioning plate 5 into the gap between the roller plates 04, and then the position of the drive frame 01 in the x-axis and y-axis directions is fine-tuned so that the x-axis positioning shaft 6 slides along the positioning seat 7 and Insert it into the mounting hole 05 on the drive frame 01, rotate the y-axis positioning bolt 8 to clamp the web 02 between the limit plate 2 and the y-axis positioning bolt 8, rotate the movable end of the rotary clamping cylinder 9 to above the wing plate 03 and then drop it, use the rotary clamping cylinder 9 to clamp the drive frame 01 to complete the overall limiting and fixation of the drive frame 01. After the processing is completed, release the rotary clamping cylinder 9 and rotate it to a safe position. The thrust cylinder 3 retreats and pulls the z-axis positioning plate 5 out of the roller plate 04. Loosen the y-axis positioning bolt 8, use the crane to lift out the processed drive frame 01, take out the x-axis positioning shaft 6, prepare for the next drive frame, and cycle the processing.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
