[0036] Example

[0037] like Figure 1 As shown, a T-slot type screw thruster comprises a T-slot type pull key 1, a worktable side groove fixing key 2, a thruster fixing plate 3, a screw thrust shaft 4, a screw thrust fixing shaft 5, a screw fixing plate gasket 6, a screw thruster wrench 7, a fixing pin 8, and a handle 9. The T-slot type pull key 1 is connected to the thruster fixing plate 3 with both ends extending out. The front end of the T-slot type pull key 1 is used to install in the T-slot of the worktable, and the rear end of the T-slot type pull key 1 is limited to the thruster fixing plate 3 by the fixing pin 8. The outer contour of the worktable side groove fixing key 2 matches the U-shaped groove 12 of the worktable and... The workbench side groove fixing key 2 is used to install in the keyway at the front end of the T-slot type tension key 1; the spiral fixing plate gasket 6 is connected to the T-slot type tension key 1, and the spiral fixing plate gasket 6 is located between the side of the workbench and the thruster fixing plate 3; the spiral thrust shaft 4 and the spiral thrust fixing shaft 5 are respectively threaded onto the thruster fixing plate 3, the front end of the spiral thrust shaft 4 is used to abut against the workpiece, and the front end of the spiral thrust fixing shaft 5 abuts against the spiral fixing plate gasket 6; the spiral thruster wrench 7 is connected to the spiral thrust shaft 4 or the spiral thrust fixing shaft 5 as needed; the handle 9 is fixed to the top of the thruster fixing plate 3.

[0038] This device consists of 9 parts, and its functions are as follows:

[0039] like Figure 4As shown, the T-slot type pull key 1 has an overall T-shaped structure. The outer contour T-shaped shape of the T-slot type pull key 1 matches the shape of the T-slot 11 of the worktable. It is fixed in the T-slot 11 of the worktable. The main functions of the T-slot type pull key 1 are to fix the entire device and transmit the pull force.

[0040] The T-slot pull key 1 has a chamfer at the front end, which is used for guiding the overall assembly of the T-slot pull key 1, such as the T-slot 11 on the workbench.

[0041] The top surface of the T-slot type pull key 1 has a U-shaped or trapezoidal keyway for connecting to the workbench side groove fixing key 2, which serves to fix the pull force. The keyway has a slight positive front angle or a right angle.

[0042] There is a plane at point E that meets the tolerance requirements, forming a right angle with point D. It has a clearance with part 2. There is a clearance at the rear end of the T-slot type tension key that has a tension limit pin that fits with part 8 to fix the entire device.

[0043] The T-slot type pull key 1 has a pin hole at its rear end, which is used to connect with the fixing pin through an interference fit, thereby limiting the position of the thruster fixing plate 3 and the spiral fixing plate gasket 6.

[0044] like Figure 5 As shown, the workbench side groove fixing key 2 has an overall trapezoidal structure and is connected to the keyway of the T-slot type tension key 1. Its main functions are to fix the entire device, transmit tension, and fix it.

[0045] The width and height of the workbench side groove fixing key 2 are matched with the workbench U-shaped groove 12.

[0046] like Figure 6 As shown, the thruster mounting plate 3 is used to connect the helical thrust shaft 4, the T-slot pull key 1 and the helical thrust fixing shaft 5, and plays the role of thrust transmission. It is required to have a certain thickness, rigidity and toughness.

[0047] The thruster mounting plate 3 is provided with a fixed threaded hole, a thrust threaded hole, a spiral fixed shaft threaded hole and a T-shaped sliding groove, all of which are through holes.

[0048] The thrust threaded hole cooperates with the spiral thrust shaft 4 to transmit thrust to the workpiece 13, thereby displacing the workpiece.

[0049] The T-shaped sliding groove cooperates with the T-shaped groove pull key 1 to fix and transmit the pull force;

[0050] The threaded hole of the spiral fixing shaft cooperates with the spiral thrust fixing shaft 5. The clamping force between the spiral fixing plate shim 6 and the side of the worktable is adjusted by the spiral thrust fixing shaft 5 to ensure the mechanical performance of the device.

[0051] The fixed threaded hole is a standard threaded hole, and the gap between the thruster mounting plate 3 and the spiral fixing plate shim 6 can be adjusted by using bolts to fit the fixed threaded hole.

[0052] like Figure 7 As shown, the spiral thrust shaft 4 is threadedly connected to the thruster mounting plate 3, and its rear end can be connected to the rotary thruster wrench 7. The main function of the spiral thrust shaft 4 is to generate rotational thrust using the rotary thruster wrench 7 to push the workpiece to produce displacement.

[0053] The front end of the spiral thrust shaft 4 is spherical, mainly to reduce the contact area and reduce the rotational thrust of the rotary thruster wrench 7, so that it can push against the side of the workpiece to exert thrust.

[0054] The rear end of the spiral thrust shaft 4 is provided with an external hexagonal structure section for connecting with the rotary thruster wrench 7.

[0055] like Figure 8 As shown, the spiral thrust fixing shaft 5 mainly functions to generate rotational thrust using the rotary thruster wrench 7 to adjust the fitting gap between the spiral fixing plate shim 6 and the worktable surface.

[0056] The front end of the spiral thrust fixing shaft 5 is flat, mainly to increase the contact area, increase the bending deformation of the spiral fixing plate 6, and push the spiral fixing plate 6 to exert thrust.

[0057] The rear end of the spiral thrust fixing shaft 5 is provided with an external hexagonal structure section, which is used to connect with the rotary thruster wrench 7 to transmit thrust.

[0058] like Figure 9 As shown, the spiral fixing plate gasket 6 is installed between the side of the machine tool worktable and the thruster fixing plate 3 to play the role of thrust transmission. It is required to have a certain thickness, rigidity and toughness.

[0059] The spiral fixing plate 6 is provided with a T-shaped sliding groove for connecting the T-shaped groove pull key 1. The bottom of the spiral fixing plate 6 is chamfered, mainly to prevent the thrust generated by the spiral thrust fixing shaft 5 from wearing the side of the worktable.

[0060] like Figure 10 As shown, the screw thruster wrench 7 can be connected to the screw thrust shaft 4 or the screw thrust fixed shaft 5 as needed.

[0061] like Figure 11 As shown, the standard part with the fixed pin at position 8 has the main function of fixing the position of the thruster fixing plate 3 and the T-slot type tension key 1, generating thrust to cause the workpiece to move.

[0062] The assembly and usage methods of this embodiment are described below:

[0063] I. Assembly Method:

[0064] First, insert the fixing pin 8 into the positioning pin at the rear end of the workbench side groove fixing key 2. Then, insert the thruster fixing plate 3 and the spiral fixing plate washer 6 into the workbench side groove fixing key 2 in sequence. Next, screw the spiral thrust shaft 4 and the spiral thrust fixing shaft 5 into the thruster fixing plate 3 respectively. Then, according to the actual use on site, install standard screws on the fixing threaded holes of the thruster fixing plate 3 as needed, adjust the fixing clearance of the spiral thruster wrench 7, and assemble the entire device for use.

[0065] II. Instructions for use:

[0066] like Figure 2 , Figure 3 As shown, before the workpiece 13 is placed on the worktable, the worktable side groove fixing key 2 is placed in the worktable U-shaped groove 12, with the center position of the worktable side groove fixing key 2 at the intersection of the worktable U-shaped groove 12 and the worktable T-shaped groove 11; then the large mold workpiece 13 is placed on the worktable, as shown. Figure 2 As shown; unscrew the worktable side groove fixing key 2 to its end, insert the T-slot type pull key 1 into the T-slot 11 of the worktable using the lifting handle 9, and pull the handle 9 upwards to align the fixing groove at the front end of the T-slot type pull key 1 with the worktable side groove fixing key 2. Then rotate the spiral thrust fixing shaft 5 to fix the entire device to the side of the worktable using the spiral thrust wrench 7. Rotate the spiral thrust shaft 4 to push its front end against the workpiece 13, and continue to rotate the spiral thrust fixing shaft 5 using the spiral thrust wrench 7 to transmit the thrust of the spiral thrust wrench 7 to the workpiece 13, thereby achieving the function of workpiece displacement.
