DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] See also Figure 1-Figure 5 The present application provides a replaceable special-shaped multi-station fixture, including a base 1 and a tooling body 2.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The base 1 is provided with two cylindrical positioning holes 11, and the bottom of the tooling body 2 is fixedly connected with two positioning columns 9, and the two positioning columns 9 are inserted into the two cylindrical positioning holes 11. The tooling body 2 is provided with four countersunk holes 12, and a positioning bolt 5 is arranged inside each countersunk hole 12. Each positioning bolt 5 is connected to the base 1, and grooves 21 are provided on both sides of the tooling body 2. Two groups of card grooves 22 are provided on the tooling body 2 at both ends of each groove 21. A limited fixing part 3 is connected to the side of the tooling body 2 at each group of card grooves 22, and a workpiece 4 is clamped inside the card groove 22. Each limited fixing part 3 limits each group of workpieces 4. Among them, when processing the workpiece 4, first place the workpiece 4 in each group of slots 22, then fix the workpiece 4 through the limit fixing member 3, then lift the tool body 2 to align the two positioning columns 9 with the two cylindrical positioning holes 11, so that the tool body 2 is located on the base 1, and then screw the positioning bolts 5 into the countersunk holes 12 to fix the tool body 2 and the base 1. When processing the workpiece 4, the tooling personnel can take another tool body 2 to clamp the workpiece 4. When the workpiece 4 on the previous tool body 2 is fully processed, loosen the positioning bolts 5, remove the tool body 2 from the base 1, and then install another tool body 2 on the base 1. Through the cooperation of the positioning columns 9 and the positioning bolts 5, the tool body 2 can be quickly replaced, so the workpiece 4 can be installed on the tool body 2 in advance, and the tool body 2 can be directly replaced each time, which can greatly reduce the clamping time and improve the processing efficiency.

[0026] In this example, two of each group of slots 22 are provided, so that one limiting fixture 3 can limit two workpieces 4 at the same time. Each limiting fixture 3 includes a limiting plate 31 and a connecting bolt 32. The connecting bolt 32 is screwed on the limiting plate 31 and screwed on the side of the tooling body 2, so that the limiting plate 31 limits the two workpieces 4 at the same time. When the workpiece 4 is clamped in the slot 22, the connecting bolt 32 is aligned with the threaded hole provided on the side of the tooling body 2, and then rotated so that the limiting plate 31 is in close contact with the outer side of the workpiece 4 to achieve the limiting fixation of the workpiece 4. By setting four groups of slots 22, eight workpieces 4 can be installed at the same time. The side uses a one-to-two method, and the limiting plate 31 is used to fix the workpiece 4 on the tooling body 2. This structure can effectively avoid the cylindrical workpiece 4 from rotating and loosening due to uneven force during the processing.

[0027] In this embodiment, the bottom of the base 1 is connected with a rotating member 7, and the rotating member 7 drives the base 1 to rotate. It also includes a mounting plate 6, on which the rotating member 7 is mounted, and the driving end of the rotating member 7 is connected to the base 1. The driving end of the rotating member 7 is fixedly connected with a rotating shaft 8, and the rotating shaft 8 is fixedly connected to the bottom of the base 1. The rotating member 7 includes a motor 71, which is mounted on the mounting plate 6, and the driving end of the motor 71 is fixedly connected with a driving shaft 72. A driven shaft 73 is fixedly sleeved on the rotating shaft 8, and a transmission belt 74 is connected to the outer sides of the driving shaft 72 and the driven shaft 73. The bottom end of the rotating shaft 8 is rotatably connected to the mounting plate 6. Among them, when the workpiece 4 needs to be rotated in the processing direction, the motor 71 is driven to rotate the driving shaft 72, and then under the action of the transmission belt 74, the driven shaft 73 is rotated, and then the rotating shaft 8 is rotated. When the rotating shaft 8 rotates, the base 1 is rotated, and then the workpiece 4 is rotated, which is convenient for processing each workpiece 4.

[0028] The working principle of the replaceable special-shaped multi-station fixture is as follows: when processing the workpiece 4, first place the workpiece 4 in each group of the slots 22, then fix the workpiece 4 through the limit fixing member 3, then lift the tool body 2 to align the two positioning columns 9 with the two cylindrical positioning holes 11, so that the tool body 2 is located on the base 1, and then screw the positioning bolts 5 into the countersunk holes 12 to fix the tool body 2 and the base 1. When processing the workpiece 4, the tooling personnel can take another tool body 2 to clamp the workpiece 4. When the workpiece 4 on the previous tool body 2 is fully processed, loosen the positioning bolts 5, remove the tool body 2 from the base 1, and then install another tool body 2 on the base 1. Through the cooperation of the positioning columns 9 and the positioning bolts 5, the tool body 2 can be quickly replaced, so the workpiece 4 can be installed on the tool body 2 in advance, and the tool body 2 can be directly replaced each time, which can greatly reduce the clamping time and improve the processing efficiency.
